The increasing life-span and epidemic of civilisation-related diseases, combined with the ever decreasing quality of the environment cumulates the exposure risks and potential for cancer development. Currently, cancer-related deaths may for the first time in history become the major cause of death in the developed countries. Furthermore, current diagnostic and therapeutic strategies are inadequate, as they are commonly failing to detect small tumours, metastases and eradicate them.</span></p> <p style="text-align: justify;"> <span style="font-size: 14px;">Exponentially growing field for research in the nanomaterials prompts an enormous potential of possible applications of nanoparticles in medicine. We focused on the applications of biocompatible, high-k oxide, nanoparticles (NPs) in the field of cancer diagnosis and therapy. This work was focused on the potential development of multimodal detection-therapeutic system with dopant-dependent contrasting properties in the magnetic and fluorescent resonance.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">Mice received suspension of hydrothermally created nanoparticles (10 mg/ml, 0.3 ml/mouse) via gastric gavage. All protocols were according to the EU guidelines and approved by 2/2012 and 13/2015 LEC agreements. Following oral administration, nanoparticles were passively targeted to all tumour tissues most probably by enhanced permeation and retention (EPR) effect. In the lungs NPs were targeted specifically to the areas of metastases making them a highly specific diagnostic tool for cancer in this tissue.</span></p> </p> </div> </div> </div> </section> </article> <article class="scientific-prog clearfix"> <section> <div class="callout"> <h4>Keynote Forum</h4> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/hanene-ali-boucetta-university-of-birmingham-uk" title="Hanene Ali-Boucetta">Hanene Ali-Boucetta</a></h4> <p>University of Birmingham, UK</p> <h6>Keynote: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/carbon-based-nanomedicines-as-anticancer-torjan-horses" title="Carbon-based nanomedicines as anticancer torjan horses">Carbon-based nanomedicines as anticancer torjan horses</a></h6> <p>Time : <b>10:40-11:20</b></p> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Hanene-Ali-Boucetta-6329-24791.jpg" alt="" title="Arpad Ambrus" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5><strong>Biography:</strong></h5> <p><p style="text-align: justify;"> <span style="font-size:14px;">Hanene Ali-Boucetta has completed her Master of Pharmacy degree from UCL School of Pharmacy.

Functionalised carbon nanotubes (&fnof;CNTs) in particular have shown their ability to deliver therapeutic molecules ranging from small anticancer molecules to macromolecules as they are uptaken by cells via an energy independent mechanism.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">While chemotherapy is still the main therapeutic modality in the treatment of cancer, there is always the issue of side effects and relapse after treatment. &fnof;CNTs can be engineered to specifically target cancer cells, increase the drug payload inside them and reduce multidrug resistance. Carbon nanotubes can therefore act as anticancer Trojan horses.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">Herein we will discuss the state of the art of &fnof;CNTs as cancer therapeutics and their potential for the delivery of cancer therapeutics in 2D cell monolayers, 3D tumour spheroids and in vivo models. We will further highlight the gaps in the field which needs to be addressed before the translational move of these nanomaterials into the clinic.</span></p> </p> </div> </div> </div> </section> </article> <article class="scientific-prog clearfix"> <section> <div class="callout"> <h4>Keynote Forum</h4> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/alain-l-fymat-international-institute-of-medicine-science-usa-1527875559" title="Alain L.

A drug may block a particular signaling pathway but within a matter of days (minutes in some cases), cancer cells begin to rely on alternate pathways to promote their survival. The simultaneous use of several drugs (“rational combination therapy”)  is meant to attack both the primary and alternate pathways to preemptively block the cancer cells' escape route. Unfortunately, the efficacy of many combination therapies has been limited because drugs have very different chemical properties, which cause them to travel to different parts of the body and enter cancer cells at different rates. The situation is considerably more complicated for brain cancer (glioblastoma multiform or octopus tumor) because the cancer cells extend their tendrils into the surrounding tissue, which is virtually inoperable, resistant to therapies, and always fatal. A major obstacle to treatment is the blood brain barrier or network of blood vessels that allows essential nutrients to enter the brain but block the passage of other substances. I will describe novel nanotechnology approaches for delivering drugs across and around the brain protective barriers.</span></p> <p>  </p> </p> </div> </div> </div> </section> </article> <article class="scientific-prog clearfix"> <section> <div class="callout"> <h4>Keynote Forum</h4> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/ziyad-s-haidar-ciib-universidad-de-los-andes-santiago-chile" title="Ziyad S.

This becomes more apparent when the amount and quality of saliva are reduced, often due to medications, Sjögren’s syndrome and especially ionizing radiation therapy for tumors of the head and neck, during which the salivary glands are included within the radiation zone. While temporarily alleviated via “intensive” regimens of palliative home and professional care, many Head and Neck Cancer patients are unable to maintain the diligence required to be effective. More considerably, those affected by irreversible salivary gland dysfunction (and/or using amifostine, I.V.) often choose to terminate their radiotherapy course pre-maturely as they become severely malnourished and experience a significant deterioration in their QoL, mainly owing to hyposalivation.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Aims: </span></b><span new="" times="">Evaluate the radioprotective effect of core-shell nanocapsules designed for sequential/timely protein(s) release, following a single local injection into murine submandibular salivary glands pre-irradiation.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Materials and Methods: </span></b><span new="" times="">Loaded core-shell nanocapsules with the protein(s) were directly administered into the salivary glands of the experimental group 24 hours before radiation and PBS was injected into the glands, likewise, for the controls. Salivary flow rates and salivary protein excretion/content were evaluated using ELISA over a 3mons. period post-treatment. Histological evaluation of structures and analysis of apoptosis/proliferation were performed. Timely bio-distribution assays followed.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Findings: </span></b><span new="" times="">Experimental animals demonstrated increased salivary flow rates compared to controls. Protein content was comparable to that of pre-radiation level. Histological evaluation revealed acinar cells with less vacuoles and nuclear aberrance in experimental group compared to controls and the amount of mucin stained by alcian blue was larger, in the latter. Protein therapy resulted in less apoptotic activities detected by TUNEL assay and similar proliferative indices as in controls.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Conclusion & Significance: </span></b><span new="" times="">Biocompatible, stable, reproducible and <i>customizable </i>core-shell nanoparticulate layer-by-layer self-assembled delivery system is presented. Our findings suggest that the local sequential release of a protein cocktail (in specific dosage and order) into murine salivary gland highly prevents radiation-induced damage via reducing apoptosis.

He received his Ph.D. degree in Biochemistry from Coimbra University in 2005. The main focus of his research is the development of lipid- and polymeric-based nanosystems for gene and drug delivery into target cells and the generation of new antitumor strategies, involving different gene therapy approaches either per se or in combination with chemotherapeutic agents. Henrique Faneca is author of more than 45 scientific papers corresponding to over 1500 citations and to an h-index of 19.</span></span></p> </p> <h5><strong>Abstract:</strong></h5> <p><p style="text-align: justify;"> <span style="font-size:14px;">Cancer is one of the major causes of death, since conventional available treatments, in most of the cases, do not allow a cure of the disease. Despite the ongoing efforts, current treatment options are associated to multiple limitations, including reduced therapeutic efficacy and high side effects.

Dysfunctional endothelium is associated with impaired generation of nitric oxide (•NO) and overproduction of superoxide (O2•¯). This work describes the study of the relationship between the degree of endothelial dysfunction and the lifespan of the cardiovascular system. Ames dwarf, transgenic giant (Tg), hypertensive (SHR) and normal mice were used for these studies. The dwarf mice appear to outlive their normal siblings by an average of at least one year. However, the Tg mice have an over-expressed growth hormone that stimulates the growth of their bodies. One of the most important features of these mice is their reduced life expectancy.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">An array of •NO, O2•¯ and peroxynitrite (ONOO¯) electrochemical nanosensors was used for the <em>in vitro </em>measurements. The balance between •NO, O2•¯ and ONOO¯ formations in Ames, giant and normal mice as well as SHR rats were investigated in their cardiovascular systems.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">More favorable kinetics of •NO production with a concurrent quenched O2•¯ release was revealed in Ames compared to normal mice. The •NO/O2•¯ peak ratio was found to be 3.0 ± 0.29 times higher for Ames dwarf than their normal siblings. The case of transgenic mice was reversed, where the •NO/O2•¯ ratio was 2.8 ± 0.22 times less than that of controls from same Tg line. The ONOO¯ release was also determined in all species.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">The rate of •NO production decreased from 1.2 + 0.1 μmol s-1 in WKY to 0.46 + 0.04 μmol s-1 in the SHR rats. Also, maximum •NO concentration in SHR was found to be much lower than that in WKY. On the other hand, the O2•¯ and ONOO¯ concentrations dramatically increased in SHR compared to WKY. Therefore, the change in dynamics of •NO release in the dysfunctional endothelium can be attributed to the increase in generation of O2•¯ as well as that of ONOO¯. Our data indicated that the reduced lifespan in Tg mice with dysfunctional endothelium is associated with high concentrations of O2•¯ and ONOO¯ that most likely leads to accumulation of tissue oxidative damage.</span></p> </p> </div> </div> </div> </section> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/henrique-faneca-university-of-coimbra-portugal">Henrique Faneca</a></h4> <p>University of Coimbra, Portugal</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/development-of-novel-nanosystems-to-mediate-combined-and-multi-target-antitumor-therapeutic-strategies">Development of novel nanosystems to mediate combined and multi-target antitumor therapeutic strategies</a></h6> <p>Time : <b>14:30-15:00</b></p> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Henrique-Faneca-59289-2760.jpg" alt="Speaker" title="Henrique Faneca" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p><p style="margin-left: 10.65pt; text-align: justify;"> <span style="color: rgb(51, 51, 51); font-family: Lato, sans-serif; font-size: 14px; text-align: justify; background-color: rgb(255, 255, 255);">Henrique Faneca is principal investigator at Centre for Neuroscience and Cell Biology, and invited assistant professor at University of Coimbra.

This study is focused on the presentation a is a novel multifunctional biocompatible nanocomposite NC-2A with intercalating and encapsulated coreshell morphology structures consisting of positively charged, non-randomly distributed AgNPs with a large contact area and low diameters (average size 8 nm). We have found that aqueous blend of intercalated polysaccharide Nanocomposites (NC) with a reactively functionalized copolymer is sensitive towards a visible light source- white Light Emitted Diode (wLED). AgNPs with a diameter in the range between 2-16 nm has been obtained by the influence of visible light source -wLED during the extremely short time around 10-12 minutes. The unique sizes of these functionalized AgNPs can be controlled by the volume ratio of a biomatrix, organic clay and partner copolymer. We observed this compound exhibits cytotoxicity in vitro against two human cancer cell linesprostate MIA PaCaII and brain U-87. The anticancer properties of this NC can be explained by the following structural factors: NC- 2A contains a combination of active chains of the protonated hydroxyl, carboxyl and amine groups, Ag+ cations and ODA-MMT. We suggest this nanocomposite be further explored for anti-cancer testing as novel biomaterial with anticancer and drug delivery potential for targeted cancer therapy in a localized use. Moreover, wLED based activation is an effective and ecofriendly route to obtain AgNPs and this application takes just 10-12 minutes after applying on the local tumor area. </div> </p> </div> </div> </div> </section> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/azita-haddadi-university-of-saskatchewan-canada">Azita Haddadi</a></h4> <p>University of Saskatchewan, Canada</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/tailored-nanoparticles-for-pharmaceutical-applications">Tailored nanoparticles for pharmaceutical applications</a></h6> <p>Time : <b>15:30-16:00</b></p> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Azita-Haddadi-59281-2746.jpg" alt="Speaker" title="Azita Haddadi" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p><div style="text-align: justify;"> Azita Haddadi is currently working as an Associate Professor in the Division of Pharmacy at University of Saskatchewan.

PAX has an anti-angiogenic activity through inhibiting vascular endothelial cell proliferation, motility and cord formation, at extremely low concentrations. Yet, side effects including hypersensitivity reactions, neurotoxicity, cardiotoxicity, and nephrotoxicity, are common, and are carrier-related/(CrEL). Multi-drug resistance (MDR) resulting in</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">chemotherapeutic failure has been reported. Cost is an issue as well. Hence, it is necessary to develop an alternative formulation fit for controlled PAX delivery. SLN (solid lipid nanoparticles) as potential anticancer drug delivery nanocarriers, exhibit a great superiority to modulate drug release, improve anti-cancer activity and overcome MDR. We developed a novel natural polymer-lipid hybrid formulation consisting of SLN as core and chitosan-hyaluronic acid (CH-HA) as a shell, with HA as the outmost layer; to enhance selectivity towards HA receptors in MCF-7 cells.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;"><strong>Aims: </strong>To investigate the potential of modified SLN for the delivery of PAX.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;"><strong>Materials and Methods: </strong>SLN loaded with PAX were prepared via high-pressure hot homogenization. Formulation parameters were optimized to obtain a high-quality delivery system. Selectivity towards HA receptors was tested in a breast cancer cell line.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;"><strong>Findings: </strong>Stable, reproducible and positively-charged nanoparticles</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">resulted. Findings reveal that CH-HA-coated SLN facilitated the targeting, cellular uptake and the time-/dose-controlled</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">delivery/release of PAX, enhancing intrinsic chemotherapeutic activities. CH exhibits an increased uptake efficiency by negatively-charged cancer cell membranes due to electrostatic interactions. HA is a bioadhesive compound capable of binding with high affinity to cell surface and intracellular receptors.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;"><strong>Conclusion & Significance: </strong>SLN are suitable carrier candidates for nanoncology given their localized, and potent cytotoxic potential overcoming MDR cancer cells. CD44, an HA receptor, is overexpressed in cancer stem cells, therefore, targeting CD44 using HA seems as a fine strategy to eliminate cells accountable for treatment failure and cancer recurrence</span></p> <p style="text-align: justify;">  </p> </p> </div> </div> </div> </section> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/rania-mustafa-sudan">Rania mustafa</a></h4> <p>Sudan</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/dendrimer-functionalized-laponite-nanodisks-loaded-with-gadolinium-for-t1-weighted-mr-imaging-applications">Dendrimer-functionalized LAPONITE脗庐 nanodisks loaded with gadolinium for T1-weighted MR imaging applications</a></h6> <p>Time : <b>15:50-16:20</b></p> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Rania-mustafa-59286-9249.png" alt="Speaker" title="Rania mustafa" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p></p> <h5>Abstract:</h5> <p><p style="text-align: justify;"> <span style="font-size:14px;">In this report, we present a facile approach to forming dendrimer-functionalized LAPONITE® (LAP) nanodisks loaded with gadolinium (Gd) for in vitro and in vivo T1-weighted MR imaging applications.

Whilst current approaches to treatment are effective, they are accompanied by significant side effects. Gold nanoparticles (AuNP) have been explored for their potential use as chemotherapeutics. AuNP’s induce hyperthermia in response to excitation by near infrared light (NIR), which then can induce apoptosis in a controlled manner. CD59, an 18–22kDa membrane protein responsible for the inhibition of complement, is over expressed in multiple cancer sites, is associated with poor prognosis (Rolland <em>et al</em> 2008) and is a potential target molecule for cancer treatment. Here research is presented relating to the ability to achieve controlled cell viability reduction using anti-human CD59 targeted gold nanoparticles. </span></p> <p style="margin-left: 5pt; text-align: justify;"> <span style="font-size: 14px;">AuNP’s (1.25µg/ml-20µg/ml) were shown to reduce HeLa cell viability in a concentration-dependent manner as assessed using MTT assay. Inclusion of polymer (PEG) coating significantly reduced (p<0.05) the impact on cell viability.  Interestingly, CD59 expression was reduced significantly following exposure to AuNP’s compared to PBS controls when assessed using fluorescent microscopy, this impact being negated by PEGylating the AuNP’s.  Further modification to conjugate an anti-human CD59 monoclonal antibody (AuNP - MaB) resulted in additional reduction in nanoparticle-induced cytotoxicity. HeLa cells treated with a combination of AuNP-MaB’s and NIR light (519/520nm) led to significant reduction in cell viability compared to untreated PBS controls (p<0.01) and untargeted AuNP (p<0.05) controls.

Therefore, DNA separation is mostly coupled with either primer-based amplification or probe based capture methods. Probe based capture method, such as using streptavidin coupled magnetic beads, however, does not increase the DNA capturing efficiency because of high level non-specific interaction. In order to overcome this limitation, we redesign the surface chemistry of capture beads by applying click chemistry. Other than the most commonly used streptavidin-biotin interaction, click chemistry employs Cu[I]-catalyzed azides-alkynes Huisgen cycloadditions (CuAAC) lead to stable and rigid triazole linkages. Along with inert silica surface coverage, triazole linkers could effectively reduce any possible non-specific interaction. Moreover, CuAAC reaction is fast, high-yielding, and highly tolerant of a variety of functional groups. It performs efficiently in aqueous media and generates stable products in the face of heat and denaturation agents. We firstly prepared magnetic nanoparticles (nanoclusters) with silica core-shell and designated super-paramagnetic behavior. In a second step, we introduced azide groups onto the surface of magnetic nanoparticles as the functionalization layer for click chemistry. Finally, we applied CuAAC click reaction for a facial and high efficient cross-linking of oligonucleotides to the silica surface. The physicochemical properties of the particles such as size, morphology, magnetic properties, crystallinity, DNA loading fully characterized by using SEM, TEM, VMS, XRD, XPS, and FT-IR techniques. The characteristic tests and DNA isolation experiments show that a biocompatible nanocluster with a dense monolayer of oligonucleotide were generated with increased the DNA capturing efficiency and decreased the non-specific interaction.</span></p> </p> </div> </div> </div> </section> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/mansur-sa-39-id-yusuf-maitama-sule-university-r-nkano-1764180844">Mansur Sa'id</a></h4> <p>Yusuf Maitama Sule University Kano</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/determination-of-infrared-raman-1h-and-13c-nmr-and-density-of-state-of-nateglinide-oral-antidiabetic-drug">Determination of Infrared, Raman, (1H and 13C)-NMR and Density of State of Nateglinide Oral Antidiabetic Drug</a></h6> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Mansur-Sa39id-59660-5239.jpg" alt="Speaker" title="Mansur Sa'id" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p></p> <h5>Abstract:</h5> <p><p> Diabetes is a defect in the body’s ability to convert excess glucose to glycogen.

Platelet Concentrates (PCs) are autologous blood extracts obtained through centrifugation of whole blood samples. The preparation procedure allows the gathering and concentration of platelets and other therapeutic blood constituents (fibrinogen/fibrin, growth factors, leukocytes and circulating cells), in clinically-usable preparations (surgical adjuvants), which may enhance, accelerate and promote tissue (hard and soft) wound healing and regeneration. Despite promising clinical observations, their overall effectiveness remains debated, to date. Today, it can be safely stated that, in oral and maxillofacial surgery, the Leukocyte and Platelet-rich Fibrin (<b>L</b>-PRF) sub-family is receiving the utmost attention, mainly due to simplicity, user-friendliness, malleability and potential cost-effectiveness, yet with outcome unpredictability.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Aims: </span></b><span new="" times="">Prepare, characterize, and evaluate a novel L-PRF bioscaffold incorporating human gingival mesenchymal stem cells and natural polymer-based nanoparticles capable to induce <i>in situ </i>healing and <i>de novo </i>local bone formation for its potential clinical application as a dental extraction socket preservation alternative strategy, immediately post-exodontia.</span></span><span new="" times=""><o:p></o:p></span></p> <p class="Default" style="text-align: justify;"> <span style="font-size:14px;"><b><span new="" times="">Materials and Methods: </span></b><span new="" times="">The resulting bioscaffold was characterized for its physico-chemico-mechanical and cytocompatibility/osteogenic properties, in vitro, followed by biocompatibility, malleability and efficacy, in vivo, in a challenging critical-sized defect model in the crania of normal WISTAR rats.

Treatment options for advanced ACC are limited. Indeed, radical tumor resection can lead to local or metastatic recurrence, and mitotane (Lysodren(®)), the only recognized adrenolytic drug, offers modest response rates, notably due to some of its physico-chemical and pharmacological properties (i.e. hydrophobicity, low bioavailability). Meantime, high cumulative doses of Lysodren(®) usually cause systemic toxicities. To reduce adverse health effects, the search of safe and efficient mitotane nano-formulations as well as the full characterization and testing of its enantiomers can represent valuable therapeutic options.</p> <p style="text-align: justify;"> Interestingly, solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) could considerably improve the efficacy of mitotane (i.e. enhanced solubility and bioavailability, progressive release of the loaded drug into blood and targeted tissues) as well as its safety (i.e. lower toxicity, higher biocompatibility). These two nano-carriers for mitotane delivery and targeting are of particular interest over other polymeric particles (i.e. low-cost, efficient and simple scaling to an industrial production level following green methods).</p> <p style="text-align: justify;"> We will show that pure and active S-(-)- mitotane is more potent than pure R-(+)-mitotane for ACC treatment, and might offer synergic or additive benefits <em>in vivo</em> when adequately combined to well-prepared and characterized solid lipid-based nanocarriers.</p> <p style="text-align: justify;">  </p> <p style="text-align: justify;"> <strong>Keywords:</strong>  Adreno-Cortical Carcinoma (ACC); solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC); Nanomedicine; Mitotane; Enantiomers; Cancer Therapy.</p> <p>  </p> </p> </div> </div> </div> </section> </article> <div class="speaker-bio-abs"> <div class="modal fade" id="biography" tabindex="-1" role="dialog" aria-labelledby="Speaker Biography"> <div class="modal-dialog" role="document"> <div class="modal-content"> </div> </div> </div> <div class="modal fade" id="abstract" tabindex="-1" role="dialog" aria-labelledby="Speaker abstract"> <div class="modal-dialog" role="document"> <div class="modal-content"> </div> </div> </div> </div>  <div class="content-box tracks"> <ul class="list-group show"> <li class="list-group-item">Impact of Nanomedicine on Health Care | Future Concepts in Nanomedicine | Nanomedicine in Cancer Therapeutics</li> </ul> </div> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4>Session Introduction</h4> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/kristine-e-danielyan-national-academy-of-sciences-of-armenia-armenia">Kristine E Danielyan</a></h4> <p>National Academy of Sciences of Armenia, Armenia</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/natural-biological-based-nano-carriers-are-preferential-for-drug-delivery">Natural, Biological Based Nano Carriers Are Preferential For Drug Delivery</a></h6> <p>Time : <b>10:40-11:10</b></p> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Kristine-E-Danielyan-59287-9846.jpg" alt="Speaker" title="Kristine E Danielyan" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p><p style="text-align: justify;"> <span style="font-size: 14px;">Dr Kristine  E.

This direction includes numerous subtypes of drug delivery and one of them is the delivery of medical compounds by means of the biological based compounds or cells: erythrocytes, albumin nano particles, macrophages, antibodies against pathology initiated receptors, their targetable parts or antibodies against circulated in the organism natural carriers of the medicines, including predominantly albumins, globulins as well as red blood cells.</span></p> <p style="margin-left: -18pt; text-align: justify;"> <span style="font-size: 14px;">In our current experiments we examined the circulation time period of another compound – allopurinol, which is known as the inhibitor of Xanthine Oxidoreductase and passed several clinical trials as the antioxidant used for the treatment of ischemic stroke.</span></p> <p style="margin-left: -18pt; text-align: justify;"> <span style="font-size: 14px;">We proposed, allopurinol in experimental settings might serve as the compound, preventing the oxidative stress, whereas the albumin micro particles might preserve oncotic pressure and prevent Blood Brain Barrier (BBB) disruption.   </span></p> <p style="margin-left: -18pt; text-align: justify;"> <span style="font-size: 14px;"><strong>Methods</strong></span></p> <p style="margin-left: -18pt; text-align: justify;"> <span style="font-size: 14px;"> Glutaraldehyde was used for the polymerization of albumin.

Graphite screen-printed electrodes (SPEs) modified with CuS-GR and PPD-GR nanocomposite and applied to advance label-free and non-enzymatice electrochemical immunosensor for quantitative determination of protein biomarker carbohydrate antigen 15-3 (CA15-3) and neuron-specific enolase (NSE), respectively. CuS-GR nanocomposite shows excellent electrocatalytic activity towards catechol as probe, which improve the sensitivity of the immunosensor. Also, It was found that the PPD-GR nanocomposite exhibits excellent electrocatalytic activity towards ascorbic acid (AA) oxidation as analytical signal based on EC′ mechanism. The CuS-GR based immunosensor exhibited a wide linear range of 1.0–150 U mL<sup>-1</sup>, with a low detection limit of 0.3 U mL<sup>-1 </sup>toward CA15-3. In the case of PPD-GR nanocomposite based immunosensor due to the excellent electrocatalytic activity of PPD-GR nanocomposite, determination of NSE antigen was based on its obstruction to the electrocatalytic oxidation of AA after binding to the surface of electrode through interaction with the anti-NSE. The proposed immunosensor exhibited a wide linear range of 1.0–1000 ng mL<sup>-1</sup>, with a low detection limit of 0.3 ng mL<sup>-1 </sup>toward NSE. These developed immunosensor showed good specificity, accuracy, stability and it was successfully applied for the determination of CA15-3 and NSE in real samples.

In the past, she had worked on (European) research projects, related to dosimetry in nuclear medicine, radiobiology - investigation of chromosomal alterations due to radiation, biochemistry of ROS-induced glutathionylation and evaluation of the role of iron ions, development of drug delivery systems and biomaterials, based on hydroxyapatite and chitosan, Monte Carlo Simulation etc. She is also a classical guitarist (BSc) and loves art and travelling</span></p> </p> <h5>Abstract:</h5> <p><p style="text-align: justify;"> <span style="font-size:14px;">The scientific community approaches the multivariate condition of cancer disease in many ways. There are still aspects of the research field of alternative cancer treatments that remains to be discovered, focusing on minimize the undesirable consequences of the conventional treatment methods. It is now well established that when TiO<sub>2</sub> nanoparticles are photo-excited, the photon energy generates pairs of electrons and holes which react with water and oxygen to yield reactive oxygen species (ROS) which can damage cancer cells. Therefore, TiO<sub>2</sub> is a promising photosensitizer against cancer.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">The aim of this study is the development of TiO<sub>2</sub> nanoparticles with the potential to photo-induce anticancer effect via the mechanism of oxidative stress upon irradiation with visible light. Surface modification by doping with metal ions improves TiO<sub>2</sub> photocatalytic activity. This process leads to reduction of electron-hole recombination, resulting in ef茂卢聛cient separation and stronger photocatalytic reactions. Particularly, silver is an important dopant, which up-regulates TiO<sub>2</sub> biological activity.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">Thus, Ag-doping of TiO<sub>2</sub> was undergone, followed by detailed characterization (XRD, micro-Raman, SEM). Cultured MCF-7 and MDA-MB-468 breast cancer epithelial cells were irradiated, using visible light, in the presence of Ag-doped TiO<sub>2</sub> aqueous dispersion. Cell viability was estimated, by MTT colorimetric assay. Western blot analysis of protein expression and characterization, as well as DNA laddering assay were used to investigate the existence of cell apoptosis.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">We demonstrated that Ag-doped TiO<sub>2</sub> nanoparticles induced apoptosis specifically in the highly malignant MDA-MB-468 cancer cells. MCF-7 cells were still unaffected, under the same circumstances. The molecular mechanism of TiO<sub>2</sub> nanoparticles cytotoxicity was associated with increased pro-apoptotic Bax expression and caspase-mediated poly (adenosine diphosphate (ADP)-ribose) polymerase (PARP) activation thus resulting in DNA fragmentation and programmed cell death.</span></p> <p style="text-align: justify;"> <span style="font-size:14px;">Further studies are already in progress, focalizing at the development of visible-light-excited co-doped TiO<sub>2</sub> nanoparticles with silver and nitrogen, for targeted cancer therapy. </span></p> </p> </div> </div> </div> </section> <section> <div class="col-md-12"> <div class="affiliation bs-callout col-md-12"> <h4><a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/speaker/reid-grimes-university-of-oklahoma-r-nlouisiana">Reid Grimes</a></h4> <p>University of Oklahoma Louisiana</p> <h6>Title: <a href="https://nanomedicine-nanotechnology.pulsusconference.com/2018/abstract/bi-functionalized-clay-nanotubes-for-anti-cancer-therapy">Bi-Functionalized Clay Nanotubes for Anti-Cancer Therapy</a></h6> <p>Time : <b>15:10-15:35</b></p> </div> </div> <div class="speaker-bio-abs"> <div class="bio-main"> <img src="https://d2cax41o7ahm5l.cloudfront.net/cme/speaker-photo/Nanomedicine-2018-Reid-Grimes-59337-8568.jpg" alt="Speaker" title="Reid Grimes" class="img-responsive thumbnail pull-left"> <div class="bio"> <h5>Biography:</h5> <p></p> <h5>Abstract:</h5> <p><p style="text-align: justify;"> <span style="font-size:14px;">Systemic toxicity is a significant drawback to a majority of chemotherapeutics currently on the market.The current research regarding multifunctional nanoparticles containing both a diagnostic and therapeutic functionality have demonstrated promise.Halloysite clay nanotubes (HNTs) are naturally forming nanoparticles with documented drug delivery applications.Recently, the synthesis of an HNT nanoparticle with both folic acid (FA) and fluorescein isothiocyanate (FITC) has been reported.The uptake of the functionalized nanoparticle into CT-26 murine colorectal cancer cells was observed through epi-fluorescent and phase contrast microscopy.HNTs have demonstrated the ability to act as a nano-container for pharmaceutical agents.The addition of a therapeutic agent to the system is currently being tested, and this presentation will outline results of the trials.Furthermore, the modification of the outer surface of HNTs with photothermal agents will be discussed.The modified HNT system described in this presentation provides a viable theranostic system for a more effective treatment option.</span></p> <p>  </p> </p> </div> </div> </div> </section>  </div> </div>  <div> </div> </div> </div></div> <!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="https://www.pulsusconference.com/assets/css/custom_style.css"> <style> .list-unstyled { font-size: 16px;
