Since bone is regenerating dynamic living tissue, it will undergo healing process naturally, it cannot recover from major bone injuries, diseases and defects. In order to overcome them, bone grafting technique was introduced. Gold standard was the best method for bone grafting for the past decades. Due to limitations of gold standard, alternative methods have been implemented. Apart from them artificial bone substitutes and bone tissue engineering have become the emerging methods with technology for bone grafting. Many bone diseases and defects will be healed permanently with these promising techniques in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20grafting" title="bone grafting">bone grafting</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20standard" title=" gold standard"> gold standard</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20substitutes" title=" bone substitutes"> bone substitutes</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title=" bone tissue engineering"> bone tissue engineering</a> </p> <a href="https://publications.waset.org/abstracts/79771/a-review-on-bone-grafting-artificial-bone-substitutes-and-bone-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">869</span> Induced Bone Tissue Temperature in Drilling Procedures: A Comparative Laboratory Study with and without Lubrication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Roseiro">L.

With this type of procedure the generated friction leads to a localized increase in temperature, which may lead to the bone necrosis. Recognizing the importance of studying this phenomenon, an experimental evaluation of the temperatures developed during the procedure of drilling bone has been done. Additionally the influence of the use of the procedure with / without additional lubrication during drilling of bone has also been done. The obtained results are presented and discussed and suggests an advantage in using additional lubrication as a way to minimize the appearance of bone tissue necrosis during bone drilling procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20necrosis" title="bone necrosis">bone necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20drilling" title=" bone drilling"> bone drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=thermography" title=" thermography"> thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/16605/induced-bone-tissue-temperature-in-drilling-procedures-a-comparative-laboratory-study-with-and-without-lubrication" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">599</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">868</span> Effect of Aerobic Exercise on Estrogen Hormone and Bone Mineral Density in Osteoporotic Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noha%20Mohamed%20Abdelhafez%20Dahy">Noha Mohamed Abdelhafez Dahy</a>, <a href="https://publications.waset.org/abstracts/search?q=Azza%20Abd%20El-Aziz"> Azza Abd El-Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Ahmed"> Eman Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20El-Sayed"> Marwa El-Sayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoporosis is a metabolic bone disease characterized by low bone mass, deterioration of bone tissue, and disruption of bone microarchitecture, which leads to compromised bone strength and an increased risk of fracture, commonly it occurs in women 10-15 years after menopause, the mean age of menopause is 51 years. Menopause is natural physiological changes primary because of decline of ovaries function with age which leads to decrease of estrogen hormone production which is the main hormone for bone continuous remodeling for bone density maintenance. Exercise increase stimulation of bone growth to keep bone mass by the effect of the mechanical stimulation, antigravity loading and stress exerted on musculoskeletal muscles.

In this project, the failure that needs to take into consideration is the bone resorption on the dental implant. Human bone has its ability to remodel after the implantation. As the dental implant is installed into the bone, the bone will detect and change the bone structure to achieve new biomechanical environment. This phenomenon is known as bone remodeling. The objective of the project is to improve the performance of dental implant by using different types of design. These designs are used to analyze and predict the failure of the dental implant by using finite element analysis (FEA) namely ANSYS. The bone is assumed to be fully attached to the implant or cement. Hence, results are then compared with other researchers. The results were presented in the form of Von Mises stress, normal stress, shear stress analysis, and displacement. The selected design will be analyzed further based on a theoretical calculation of bone remodeling on the dental implant. The results have shown that the design constructed passed the failure analysis. Therefore, the selected design is proven to have a stable performance at the recovery stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20implant" title="dental implant">dental implant</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20remodeling" title=" bone remodeling"> bone remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a> </p> <a href="https://publications.waset.org/abstracts/19662/design-improvement-of-dental-implant-based-on-bone-remodelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19662.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">501</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">866</span> Assessment of the Radiation Absorbed Dose Produced by Lu-177, Ra-223, AC-225 for Metastatic Prostate Cancer in a Bone Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Tajadod">Maryam Tajadod</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The treatment of cancer is one of the main challenges of nuclear medicine; while cancer begins in an organ, such as the breast or prostate, it spreads to the bone, resulting in metastatic bone. In the treatment of cancer with radiotherapy, the determination of the involved tissues’ dose is one of the important steps in the treatment protocol. Comparing absorbed doses for Lu-177 and Ra-223 and Ac-225 in the bone marrow and soft tissue of bone phantom with evaluating energetic emitted particles of these radionuclides is the important aim of this research. By the use of MCNPX computer code, a model for bone phantom was designed and the values of absorbed dose for Ra-223 and Ac-225, which are Alpha emitters & Lu-177, which is a beta emitter, were calculated. As a result of research, in comparing gamma radiation for three radionuclides, Lu-177 released the highest dose in the bone marrow and Ra-223 achieved the lowest level. On the other hand, the result showed that although the figures of absorbed dose for Ra and Ac in the bone marrow are near to each other, Ra spread more energy in cortical bone. Moreover, The alpha component of the Ra-223 and Ac-225 have very little effect on bone marrow and soft tissue than a beta component of the lu-177 and it leaves the highest absorbed dose in the bone where the source is located. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20metastases" title="bone metastases">bone metastases</a>, <a href="https://publications.waset.org/abstracts/search?q=lutetium-177" title=" lutetium-177"> lutetium-177</a>, <a href="https://publications.waset.org/abstracts/search?q=radium-223" title=" radium-223"> radium-223</a>, <a href="https://publications.waset.org/abstracts/search?q=actinium-225" title=" actinium-225"> actinium-225</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbed%20dose" title=" absorbed dose"> absorbed dose</a> </p> <a href="https://publications.waset.org/abstracts/149268/assessment-of-the-radiation-absorbed-dose-produced-by-lu-177-ra-223-ac-225-for-metastatic-prostate-cancer-in-a-bone-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">865</span> Identification of the Orthotropic Parameters of Cortical Bone under Nanoindentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Remache">D.

Berkovich nanoindentation tests were performed on the human cortical bone to extract its orthotropic parameters. The nanoindentation experiments were then simulated by the finite element method. Different configurations of interactions between the tip indenter and the bone were simulated. The orthotropic parameters of the material were identified by the inverse method for each configuration.

In this work, the absorbed dose of 153Sm-TTHMP and 153Sm-PDTMP to each human organ was evaluated based on biodistribution studies in rats by radiation dose assessment resource (RADAR) method. The highest absorbed dose for 153Sm-TTHMP and 153Sm-PDTMP is observed in trabecular bone with 1.844 and 3.167 mGy/MBq, respectively. Bone/red marrow dose ratio, as the target/critical organ dose ratio, for 153Sm-PDTMP is greater than 153Sm-TTHMP and is compatible with 153Sm-EDTMP. The results showed that these bone-seeking agents, specially 153Sm-PDTMP, have considerable characteristics compared to the most clinically used bone pain palliative radiopharmaceutical, and therefore, can be good candidates for bone pain palliation in patients with bone metastasis; however, further biological studies in other mammals are still needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20dosimetry" title="internal dosimetry">internal dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=PDTMP" title=" PDTMP"> PDTMP</a>, <a href="https://publications.waset.org/abstracts/search?q=153Sm" title=" 153Sm"> 153Sm</a>, <a href="https://publications.waset.org/abstracts/search?q=TTHMP" title=" TTHMP"> TTHMP</a> </p> <a href="https://publications.waset.org/abstracts/18061/preliminary-dosimetric-evaluation-of-two-new-153sm-bone-pain-palliative-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">548</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">863</span> Characterization of Fish Bone Catalyst for Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarina%20Sulaiman">Sarina Sulaiman</a>, <a href="https://publications.waset.org/abstracts/search?q=N.Khairudin"> N.Khairudin </a>, <a href="https://publications.waset.org/abstracts/search?q=P.Jamal"> P.Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Z.%20Alam"> M.Z.

Similar to minerals, the inner eggshell membrane consists of carbohydrates, lipids, proteins with the high pH, high calcium absorptive capacity and with faster bone fracture repair ability. In the present radiographic survey, eggshell-derived bone graft substitutes were used for bone defect repair in 8 dog tibia, measuring bone density on the day of implant placement and 30 and 60 days after placement. In fact, the result of this study shows the difference in bone growth and misshapen bones between treatment and control sites. Cell growth was adequate in treatment sites and misshapen bones were less frequent here than in control sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20repair" title="bone repair">bone repair</a>, <a href="https://publications.waset.org/abstracts/search?q=eggshell%20powder" title=" eggshell powder"> eggshell powder</a>, <a href="https://publications.waset.org/abstracts/search?q=implant" title=" implant"> implant</a>, <a href="https://publications.waset.org/abstracts/search?q=radiography" title=" radiography"> radiography</a> </p> <a href="https://publications.waset.org/abstracts/34008/a-radiographic-survey-of-eggshell-powder-effect-on-tibial-bone-defect-repair-tested-in-dog" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">861</span> Ultrasonic Densitometry of Bone Tissue of Jaws and Phalanges of Fingers in Patients after Orthodontic Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarita%20Belousova">Margarita Belousova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ultrasonic densitometry (RU patent № 2541038) was used to assess the density of the bone tissue in the jaws of patients after orthodontic treatment.

The presence of bromide salts in seawater may result in increased levels of bromine and brominated byproducts in drinking water. The State of Qatar offers a unique setting to study these pollutants and their impacts on consumers as the country is 100% dependent on seawater desalination to supply municipal tap water and locally produced bottled water. Tap water (n=115) and bottled water (n=62) samples were collected throughout the State of Qatar and analyzed for a suite of inorganic and organic compounds, including 54 volatile organic compounds (VOCs), with an emphasis on brominated byproducts. All VOC identification and quantification was completed using a Bruker Scion GCMSMS with static headspace technologies. A risk survey tool was used to collect information regarding local consumption habits, health outcomes and perception of water sources for adults and children. This study is the first of its kind in the country. Dibromomethane, bromoform, and bromobenzene were detected in 61%, 88% and 2%, of the drinking water samples analyzed. The levels of dibromomethane ranged from approximately 100-500 ng/L and the concentrations of bromoform ranged from approximately 5-50 µg/L. Additionally, bromobenzene concentrations were 60 ng/L. The presence of brominated compounds in drinking water is a public health concern specific to populations using seawater as a feed water source and may pose unique risks that have not been previously studied. Risk assessments are ongoing to quantify the risks associated with prolonged consumption of disinfection byproducts; specifically the risks of brominated trihalomethanes as the levels of bromoform found in Qatar’s drinking water reach more than 60% of the US EPA’s Maximum Contaminant Level of all THMs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brominated%20byproducts" title="brominated byproducts">brominated byproducts</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=trihalomethanes" title=" trihalomethanes"> trihalomethanes</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a> </p> <a href="https://publications.waset.org/abstracts/23417/alternative-water-resources-and-brominated-byproducts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23417.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">857</span> A Comparison of Implant Stability between Implant Placed without Bone Graft versus with Bone Graft Using Guided Bone Regeneration (GBR) Technique: A Resonance Frequency Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Janyaphadungpong">R.

Pimkhaokham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This prospective clinical study determined the insertion torque (IT) value and monitored the changes in implant stability quotient (ISQ) values during the 12 weeks healing period from implant placement without bone graft (control group) and with bone graft using the guided bone regeneration (GBR) technique (study group). The relationship between the IT and ISQ values of the implants was also assessed. The control and study groups each consisted of 6 patients with 8 implants per group. The ASTRA TECH Implant System™ EV 4.2 mm in diameter was placed in the posterior mandibular region. In the control group, implants were placed in bone without bone graft, whereas in the study group implants were placed simultaneously with the GBR technique at favorable bone defect. IT (Ncm) of each implant was recorded when fully inserted. ISQ values were obtained from the Osstell® ISQ at the time of implant placement, and at 2, 4, 8, and 12 weeks. No difference in IT was found between groups (P = 0.320). The ISQ values in the control group were significantly higher than in the study group at the time of implant placement and at 4 weeks. There was no significant association between IT and ISQ values either at baseline or after the 12 weeks. At 12 weeks of healing, the control and study groups displayed different trends. Mean ISQ values for the control group decreased over the first 2 weeks and then started to increase. ISQ value increases were statistically significant at 8 weeks and later, whereas mean ISQ values in the study group decreased over the first 4 weeks and then started to increase, with statistical significance after 12 weeks. At 12 weeks, all implants achieved osseointegration with mean ISQ values over the threshold value (ISQ>70). These results indicated that implants, in which guided bone regeneration technique was performed during implant placement for treating favorable bone defects, were as predictable as implants placed without bone graft. However, loading in implants placed with the GBR technique for correcting favorable bone defects should be performed after 12 weeks of healing to ensure implant stability and osseointegration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20implant" title="dental implant">dental implant</a>, <a href="https://publications.waset.org/abstracts/search?q=favorable%20bone%20defect" title=" favorable bone defect"> favorable bone defect</a>, <a href="https://publications.waset.org/abstracts/search?q=guided%20bone%20regeneration%20technique" title=" guided bone regeneration technique"> guided bone regeneration technique</a>, <a href="https://publications.waset.org/abstracts/search?q=implant%20stability" title=" implant stability"> implant stability</a> </p> <a href="https://publications.waset.org/abstracts/62198/a-comparison-of-implant-stability-between-implant-placed-without-bone-graft-versus-with-bone-graft-using-guided-bone-regeneration-gbr-technique-a-resonance-frequency-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62198.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">856</span> Mechanical Cortical Bone Characterization with the Finite Element Method Based Inverse Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Remache">Djamel Remache</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Semaan"> Marie Semaan</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9cile%20Baron"> Cécile Baron</a>, <a href="https://publications.waset.org/abstracts/search?q=Martine%20Pithioux"> Martine Pithioux</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Chabrand"> Patrick Chabrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Marie%20Rossi"> Jean-Marie Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Louis%20Milan"> Jean-Louis Milan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cortical bone is a complex multi-scale structure.

This is done via reconstruction of bone and appropriate biological joint with bone tissues of damaged areas. In this study the condition of biodegradable bed Nanofibrous PHBV and USSC cells were used to accelerate bone repair of damaged area. Hollow nanofabrication scaffold of damageable life was designed as PHBV by electrospinning and via determining the best factors such as the kind and amount of solvent, specific volume and rate. The separation of osseous tissue infiltration and evaluating its nature by flow cytometrocical analysis was done. Animal test including USSC as well as PHBV condition in the damaged bone was done in the rat. After 8 weeks the implanted area was analyzed using CT scan and was sent to histopathology ward. Finally, the rate and quality of reconstruction were determined after H and E coloring. Histomorphic analysis indicated a statistically significant difference between the experimental group of PHBV, USSC+PHBV and control group. Besides, the histopathologic analysis showed that bone reconstruction rate was high in the area containing USSC and PHBV, compared with area having PHBV and control group and consequently the reconstruction quality of bones and the relationship between the new bone tissues and surrounding bone tissues were high too. Using PHBR scaffold and USSC together could be useful in the amending of wide range of bone lesion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20lesion" title="bone lesion">bone lesion</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibrous%20PHBV" title=" nanofibrous PHBV"> nanofibrous PHBV</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20cord%20blood" title=" umbilical cord blood"> umbilical cord blood</a> </p> <a href="https://publications.waset.org/abstracts/21192/reconstructing-calvarial-bone-lesions-using-phbv-scaffolds-and-cord-blood-mesenchymal-stem-cells-in-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21192.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">851</span> Stress-Strain Relation for Human Trabecular Bone Based on Nanoindentation Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marek%20Pawlikowski">Marek Pawlikowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Jankowski"> Krzysztof Jankowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstanty%20Skalski"> Konstanty Skalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Makuch"> Anna Makuch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanoindentation or depth-sensing indentation (DSI) technique has proven to be very useful to measure mechanical properties of various tissues at a micro-scale. Bone tissue, both trabecular and cortical one, is one of the most commonly tested tissues by means of DSI. Most often such tests on bone samples are carried out to compare the mechanical properties of lamellar and interlamellar bone, osteonal bone as well as compact and cancellous bone. In the paper, a relation between stress and strain for human trabecular bone is presented. The relation is based on the results of nanoindentation tests. The formulation of a constitutive model for human trabecular bone is based on nanoindentation tests. In the study, the approach proposed by Olivier-Pharr is adapted. The tests were carried out on samples of trabecular tissue extracted from human femoral heads. The heads were harvested during surgeries of artificial hip joint implantation. Before samples preparation, the heads were kept in 95% alcohol in temperature 4 Celsius degrees. The cubic samples cut out of the heads were stored in the same conditions. The dimensions of the specimens were 25 mm x 25 mm x 20 mm. The number of 20 samples have been tested. The age range of donors was between 56 and 83 years old. The tests were conducted with the indenter spherical tip of the diameter 0.200 mm. The maximum load was P = 500 mN and the loading rate 500 mN/min. The data obtained from the DSI tests allows one only to determine bone behoviour in terms of nanoindentation force vs. nanoindentation depth. However, it is more interesting and useful to know the characteristics of trabecular bone in the stress-strain domain. This allows one to simulate trabecular bone behaviour in a more realistic way. The stress-strain curves obtained in the study show relation between the age and the mechanical behaviour of trabecular bone. It was also observed that the bone matrix of trabecular tissue indicates an ability of energy absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constitutive%20model" title="constitutive model">constitutive model</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behaviour" title=" mechanical behaviour"> mechanical behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title=" nanoindentation"> nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=trabecular%20bone" title=" trabecular bone"> trabecular bone</a> </p> <a href="https://publications.waset.org/abstracts/74950/stress-strain-relation-for-human-trabecular-bone-based-on-nanoindentation-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74950.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">850</span> Benign Osteoblastoma of the Mandible Resection and Replacement of the Defects with Decellularized Cattle Bone Scaffold with Mesenchymal Bone Marrow Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Mardaleishvili">K.

The crushed bones were divided into two, where one part was turned to ash while the other part was pulverized with laboratory ball mill before the two grades were sieved using 75 µm sieve size. Bone ash and bone particle reinforced tensile and flexural composite samples were developed from pre-determined proportions of 2, 4, 6, and 8 %. The samples after curing were stripped from the moulds and were allowed to further cure for 3 weeks before tensile and flexural tests were performed on them. The tensile test result showed that, 8 wt % bone particle reinforced polyester composites has higher tensile properties except for modulus of elasticity where 8 wt % bone ash particle reinforced composites has higher value while for flexural test, bone ash particle reinforced composites demonstrate the best flexural properties. The results show that these materials are structurally compatible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomedical" title="biomedical">biomedical</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20bone" title=" cow bone"> cow bone</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polyester" title=" polyester"> polyester</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement"> reinforcement</a> </p> <a href="https://publications.waset.org/abstracts/47045/influence-of-modified-and-unmodified-cow-bone-on-the-mechanical-properties-of-reinforced-polyester-composites-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47045.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">847</span> Inverse Mode Shape Problem of Hand-Arm Vibration (Humerus Bone) for Bio-Dynamic Response Using Varying Boundary Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajay%20R">Ajay R</a>, <a href="https://publications.waset.org/abstracts/search?q=Rammohan%20B"> Rammohan B</a>, <a href="https://publications.waset.org/abstracts/search?q=Sridhar%20K%20S%20S"> Sridhar K S S</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurusharan%20%20N"> Gurusharan N</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of the work is to develop a numerical method to solve the inverse mode shape problem by determining the cross-sectional area of a structure for the desired mode shape via the vibration response study of the humerus bone, which is in the form of a cantilever beam with anisotropic material properties.

This phenomenon arises from various external stimuli, such as human speech, chewing, and walking, which generate vibrations transmitted through the body to the ear canal walls. The bone-conducted OE occurs due to the pressure build-up inside the occluded ear caused by sound radiating into the ear canal cavity from its walls. In the hearing aid industry, artificial ears are utilized as a tool for developing hearing aids. However, the currently available commercial artificial ears primarily focus on pure acoustics measurements, neglecting the bone-conducted vibration aspect. This research endeavors to develop an artificial ear specifically designed for bone-conducted occlusion measurements. Finite element analysis (FEA) modeling has been employed to gain insights into the behavior of the artificial ear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20ear" title="artificial ear">artificial ear</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20conducted%20vibration" title=" bone conducted vibration"> bone conducted vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=occlusion%20measurement" title=" occlusion measurement"> occlusion measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a> </p> <a href="https://publications.waset.org/abstracts/168626/development-of-an-artificial-ear-for-bone-conducted-objective-occlusion-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168626.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">845</span> Preservation of Phenytoin and Sodium Valproate Induced Bone Loss by Raloxifene through Modulating Serum Estradiol and TGF-β3 Content in Bone of Female Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Divya%20Vohora">Divya Vohora</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.%20Jamir%20Anwar"> Md. Jamir Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antiepileptic drugs (AEDs)-induced adverse consequences on bone are now well recognized. Despite this, there is limited data on the effect of anti-osteoporotic therapies on AEDs-induced bone loss. Both phenytoin (PHT) and sodium valproate (SVP) inhibit human aromatase enzyme and stimulate microsomal catabolism of oestrogens. Estrogen deficiency states are known to reduce the deposition of transforming growth factor-β (TGF-β3), a bone matrix protein, having anti-osteoclastic property. Thus, an attempt was made to investigate the effect of raloxifene, a selective oestrogen receptor modulator, in comparison with CVD supplementation, on PHT and SVP-induced alterations in bone in mice. Further, the effect of raloxifene on seizures and on the antiepileptic efficacy of AEDs was also investigated. Swiss strains of female mice were treated with PHT (35 mg/kg, p.o.) and SVP (300 mg/kg, p.o.) for 120 days to induce bone loss as evidenced by reduced bone mineral density (BMD) and altered bone turnover markers in lumbar bones (alkaline phosphatase, tartarate resistant acid phosphatase, hydroxyproline) and urine (calcium). The bone loss was accompanied by reduced serum estradiol levels and bone TGF-β3 content. Preventive and curative treatment with raloxifene ameliorated bony alterations and was more effective than CVD. Deprived estrogen levels (that in turn reduced lumbar TGF-β3 content) following PHT and SVP, thus, might represent one of the various mechanisms of AEDs-induced bone loss. Raloxifene preserved the bony changes without interfering with their antiepileptic efficacy, and hence raloxifene could be a potential therapeutic option in the management of PHT and SVP-induced bone disease if clinically approved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiepileptic%20drugs" title="antiepileptic drugs">antiepileptic drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis"> osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=raloxifene" title=" raloxifene"> raloxifene</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF-%CE%B23" title=" TGF-β3"> TGF-β3</a> </p> <a href="https://publications.waset.org/abstracts/16217/preservation-of-phenytoin-and-sodium-valproate-induced-bone-loss-by-raloxifene-through-modulating-serum-estradiol-and-tgf-v3-content-in-bone-of-female-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16217.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">844</span> Differentiated Thyroid Cancer Presenting with Solitary Bony Metastases to the Frontal Bone of the Skull</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christy%20M.%20Moen">Christy M.

A literature review found only six cases of thyroid cancer that metastasised to the frontal bone, with two of those involving further bone sites. Case Report: The patient was originally referred to the Oral and Maxillofacial Surgery team with an isolated mass on her forehead. Biopsies were performed, which showed this was likely a metastatic deposit from thyroid cancer. CT-PET scan showed this was an isolated lesion. The patient had a total thyroidectomy, and the forehead lesion was managed with radiotherapy. On interval scanning, the patient’s bony lesion had increased in size and had new lung nodules, which likely represented further metastasis. Conclusion: Isolated bony metastases to the frontal bone are rare. An important clinical principle to remember is that a bony metastasis from an unknown primary is more likely than primary bone cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid" title=" thyroid"> thyroid</a>, <a href="https://publications.waset.org/abstracts/search?q=head%20and%20neck" title=" head and neck"> head and neck</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/138043/differentiated-thyroid-cancer-presenting-with-solitary-bony-metastases-to-the-frontal-bone-of-the-skull" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138043.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">843</span> Bone Mineral Density and Quality, Body Composition of Women in the Postmenopausal Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vladyslav%20Povoroznyuk">Vladyslav Povoroznyuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Oksana%20Ivanyk"> Oksana Ivanyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Nataliia%20Dzerovych"> Nataliia Dzerovych</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the diagnostics of osteoporosis, the gold standard is considered to be bone mineral density; however, X-ray densitometry is not an accurate indicator of osteoporotic fracture risk under all circumstances. In this regard, the search for new methods that could determine the indicators not only of the mineral density, but of the bone tissue quality, is a logical step for diagnostic optimization. One of these methods is the evaluation of trabecular bone quality. The aim of this study was to examine the quality and mineral density of spine bone tissue, femoral neck, and body composition of women depending on the duration of the postmenopausal period, to determine the correlation of body fat with indicators of bone mineral density and quality. The study examined 179 women in premenopausal and postmenopausal periods. The patients were divided into the following groups: Women in the premenopausal period and women in the postmenopausal period at various stages (early, middle, late postmenopause). A general examination and study of the above parameters were conducted with General Electric X-ray densitometer. The results show that bone quality and mineral density probably deteriorate with advancing of postmenopausal period. Total fat and lean mass ratio is not likely to change with age. In the middle and late postmenopausal periods, the bone tissue mineral density of the spine and femoral neck increases along with total fat mass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title="osteoporosis">osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20mineral%20density" title=" bone tissue mineral density"> bone tissue mineral density</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20quality" title=" bone quality"> bone quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fat%20mass" title=" fat mass"> fat mass</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20mass" title=" lean mass"> lean mass</a>, <a href="https://publications.waset.org/abstracts/search?q=postmenopausal%20osteoporosis" title=" postmenopausal osteoporosis"> postmenopausal osteoporosis</a> </p> <a href="https://publications.waset.org/abstracts/66298/bone-mineral-density-and-quality-body-composition-of-women-in-the-postmenopausal-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66298.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">842</span> Stimulation of NCAM1-14.3.3.ζδ-derived Peptide Interaction Fuels Angiogenesis and Osteogenesis in Ageing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taha%20Kadir%20Yesin">Taha Kadir Yesin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanyu%20Liu"> Hanyu Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhangfan%20Ding"> Zhangfan Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Singh"> Amit Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi%20Tian"> Qi Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuheng%20Zhang"> Yuheng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Biswajyoti%20Borah"> Biswajyoti Borah</a>, <a href="https://publications.waset.org/abstracts/search?q=Junyu%20Chen"> Junyu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Anjali%20P.%20Kusumbe"> Anjali P.

At the core of osteogenesis and bone formation lies the dynamic process of angiogenesis. In this study, we reveal a potent endogenous anabolic NCAM1-14.3.3. ζδ-derived- Peptide interaction, which stimulates bone angiogenesis and osteogenesis during homeostasis, aging, and age-related bone diseases. Employing high-resolution imaging and inducible cell-specific mouse genetics, our results elucidate the pivotal role of the NCAM1-14.3.3.ζδ-derived-Peptide interaction in driving the expansion of Clec14a+ angiogenic endothelial cells. Notably, Clec14a+ endothelial cells express key osteogenic factors. The NCAM1-14.3.3.ζδ-derived-Peptide interaction in osteoblasts drives osteoblast differentiation, ultimately contributing to the genesis of bone. Moreover, the NCAM1-14.3.3.ζδ-derived-Peptide interaction leads to a reduction in bone resorption. In age-associated vascular and bone loss diseases, stimulating the NCAM1-14.3.3.ζδ-derived-Peptide interaction not only promotes angiogenesis but also reverses bone loss. Consequently, harnessing the endogenous anabolic potential of the NCAM1-14.3.3.ζδ-derived-Peptide interaction emerges as a promising therapeutic modality for managing age-related bone diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endothelial%20cell" title="endothelial cell">endothelial cell</a>, <a href="https://publications.waset.org/abstracts/search?q=NCAM1" title=" NCAM1"> NCAM1</a>, <a href="https://publications.waset.org/abstracts/search?q=Clec14a" title=" Clec14a"> Clec14a</a>, <a href="https://publications.waset.org/abstracts/search?q=14.3.3.%CE%B6%CE%B4" title=" 14.3.3.ζδ"> 14.3.3.ζδ</a> </p> <a href="https://publications.waset.org/abstracts/184055/stimulation-of-ncam1-1433zd-derived-peptide-interaction-fuels-angiogenesis-and-osteogenesis-in-ageing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184055.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">841</span> Production and Quality Control of a Novel 153Sm-Complex for Radiotherapy of Bone-Metastases </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Yousefnia">H.

The aim of this study was the preparation of 153Sm-(4-{[bis-(phosphonomethyl))carbamoyl]methyl}-7,10-bis(carboxymethyl) 1,4,7,10-tetraazacyclododec-1-yl) acetic acid (BPAMD) for bone pain palliation therapy. 153Sm was produced at Tehran research reactor via 152Sm(n,γ)153Sm reaction. 200 µl of 1mg/ml BPAMD solution was added to the vial containing 1 mCi 153Sm and the mixture was heated up to 90 0C for 1 h. The radiochemical purity of the complex was measured by ITLC method. The final solution with radiochemical purity of more than 95% was injected to BALB mice and bio distribution was determined up to 48 h. SPECT images were acquired after 2 and 24 h post injection. While high bone uptake was confirmed by both the bio distribution studies and SPECT imaging, accumulation in other organs was approximately negligible. The results show that 153Sm-BPAMD can be used as an excellent tracer for bone pain palliation therapy. <p class="card-text"><strong>Keywords:</strong> <a
