regarded as beneficial in the therapy of central obesity-associated metabolic abnormalities. However, in the traditional diet of the Central European countries, food items with positive nutritional profiles (rye bread, oats, buckwheat, herrings, linseed and rapeseed oil, berries, apples, plums, root vegetables etc.) are also used. We hypothesized that the Central European Diet (CED) may be comparatively effective in reducing symptoms of central obesity as MED. We tested the health effects of the CED, which is an environmentally friendly regional diet and the traditional MED diet in a group of postmenopausal centrally obese women. A total 58 with a mean age of 60 y (50-70y), body mass index (in kg/m(2)) of 33.4 (22.6-47.3), and waist circumference of 105 cm (87.5-137 cm) were randomly assigned to receive either the diet based on food items commonly used in Central Europe (the CED group; n = 29) or the Mediterranean diet (the MED group; n = 29) for 15 weeks. Body mass and body composition were measured with a Bod Pod (Cosmed, Italy). A non-elastic flexible measuring tape was used to measure waist circumference. Additionally, blood pressure, plasma lipid and glucose levels were assessed with the use of a biochemical analyzer. A total of 50 subjects [86% (CED 83%; MED 90%)] completed the intervention. A high dietary compliance for both described diets was achieved. The mean (±SEM) weight and waist circumference changes were -7.4 ± 0.7 kg; -8.3 ± 0.7 cm and -8.1 ± 0.5 kg; -7.1 ± 0.6 cm for the CED and MED groups, respectively. Moreover, there were no differences between the effectiveness of the diets used in terms of the influence on fat mass, blood pressure, and biochemical parameters. The preliminary data suggest that both described diets may be successfully used for improving central obesity-associated metabolic abnormalities.

Lower 2D:4D is linked with greater physical ability, strength, and better sporting performance. Second-to-fourth digit lengths ratio (2D:4D) is an indicator of PT exposure. Lower 2D:4D indicates higher PT exposure and vice versa. Methods: The objectives of this paper were to investigate the relationship of 2D:4D with physical fitness in men and women. The study compared 137 female and 174 male students from Wrocław. Besides calculating 2D:4D for each hand, height and weight were also recorded. Assessment of physical fitness and endurance were performed through Eurofit tests. Handgrip strength was measured by a standardized isometric dynamometer. Results: Male participants had significantly lower 2D:4D than females on each hand. A weak relationship between 2D:4D and the results of strength tests was found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D%3A4D" title="2D:4D">2D:4D</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20fitness" title=" physical fitness"> physical fitness</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20testosterone" title=" prenatal testosterone"> prenatal testosterone</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20dimorphism" title=" sexual dimorphism"> sexual dimorphism</a> </p> <a href="https://publications.waset.org/abstracts/151606/the-ratio-of-second-to-fourth-digit-length-2d4d-and-the-physical-ability-in-men-and-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151606.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">125</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">7</span> Improve of Biomass Properties through Torrefaction Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malgorzata%20Walkowiak">Malgorzata Walkowiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Witczak"> Magdalena Witczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Cichy"> Wojciech Cichy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomass is an important renewable energy source in Poland. As a biofuel, it has many advantages like renewable in noticeable time and relatively high energy potential. But disadvantages of biomass like high moisture content and hygroscopic nature causes that gaining, transport, storage and preparation for combustion become troublesome and uneconomic. Thermal modification of biomass can improve hydrophobic properties, increase its calorific value and natural resistance. This form of thermal processing is known as torrefaction. The aim of the study was to investigate the effect of the pre-heat treatment of wood and plant lignocellulosic raw materials on the properties of solid biofuels. The preliminary studies included pine, beech and willow wood and other lignocellulosic raw materials: mustard, hemp, grass stems, tobacco stalks, sunflower husks, Miscanthus straw, rape straw, cereal straw, Virginia Mallow straw, rapeseed meal. Torrefaction was carried out using variable temperatures and time of the process, depending on the material used. It was specified the weight loss and the ash content and calorific value was determined. It was found that the thermal treatment of the tested lignocellulosic raw materials is able to provide solid biofuel with improved properties. In the woody materials, the increase of the lower heating value was in the range of 0,3 MJ/kg (pine and beech) to 1,1 MJ/kg (willow), in non-woody materials – from 0,5 MJ/kg (tobacco stalks, Miscanthus) to 3,5 MJ/kg (rapeseed meal). The obtained results indicate for further research needs, particularly in terms of conditions of the torrefaction process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20materials" title=" lignocellulosic materials"> lignocellulosic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20biofuels" title=" solid biofuels"> solid biofuels</a>, <a href="https://publications.waset.org/abstracts/search?q=torrefaction" title=" torrefaction"> torrefaction</a> </p> <a href="https://publications.waset.org/abstracts/53382/improve-of-biomass-properties-through-torrefaction-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53382.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">237</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">6</span> Study on Carbon Nanostructures Influence on Changes in Static Friction Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafa%C5%82%20Urbaniak">Rafał Urbaniak</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20K%C5%82osowiak"> Robert Kłosowiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Micha%C5%82%20Cia%C5%82kowski"> Michał Ciałkowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Bartoszewicz"> Jarosław Bartoszewicz </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Chair of Thermal Engineering at Poznan University of Technology has been conducted research works on the possibilities of using carbon nanostructures in energy and mechanics applications for a couple of years. Those studies have provided results in a form of co-operation with foreign research centres, numerous publications and patent applications. Authors of this paper have studied the influence of multi-walled carbon nanostructures on changes in static friction arising when steel surfaces were moved. Tests were made using the original test stand consisting of automatically controlled inclined plane driven by precise stepper motors. Computer program created in the LabView environment was responsible for monitoring of the stand operation, accuracy of measurements and archiving the obtained results. Such a solution enabled to obtain high accuracy and repeatability of all conducted experiments. Tests and analysis of the obtained results allowed us to determine how additional layers of carbon nanostructures influenced on changes of static friction coefficients. At the same time, we analyzed the potential possibilities of applying nanostructures under consideration in mechanics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title="carbon nanotubes">carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20friction" title=" static friction"> static friction</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20friction" title=" dynamic friction"> dynamic friction</a> </p> <a href="https://publications.waset.org/abstracts/26601/study-on-carbon-nanostructures-influence-on-changes-in-static-friction-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26601.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">314</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">5</span> Cryogenic Separation of CO2 from Molten Carbonate Fuel Cell Anode Outlet—Experimental Guidelines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%C2%A0Milewski">Jarosław Milewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafa%C5%82%C2%A0Bernat"> Rafał Bernat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analysis of using cryogenic separation unit for recovering fuel from anode off gas of molten carbonate fuel cells (MCFCs) in order to upgrade the efficiently of the unit. In the proposed solution, the CSU is used for condensing water and carbon dioxide from anode off gas, and re-cycling the rest of the stream to the anode, saving certain amount of fuel (at least 30%). The resulting system efficiency is increased considerably. CSU, virtually consumes power, thus this solution has energy penalty as well, on the other hand, MCFC generates large amount of heat at elevated temperature, thus part of the CSU can be based on absorption chiller. In all cases, a high amount of fuel is obtained after condensation of water and carbon dioxide and re-cycled to the anode inlet. Based on mathematical modeling done previously, the concept and guidelines for forthcoming experimental investigations are presented in this paper. During planned experiments, an existing single cell laboratory stand will be equipped with re-cycle device (a fan, a peristaltic pump, etc.). Parallel, a mixture of anode off gas will be cooled down for determining the proper temperature for the separation of water and carbon dioxide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryogenic%20separation" title="cryogenic separation">cryogenic separation</a>, <a href="https://publications.waset.org/abstracts/search?q=experiments" title=" experiments"> experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cells" title=" fuel cells"> fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20carbonate%20fuel%20cells" title=" molten carbonate fuel cells"> molten carbonate fuel cells</a> </p> <a href="https://publications.waset.org/abstracts/41874/cryogenic-separation-of-co2-from-molten-carbonate-fuel-cell-anode-outlet-experimental-guidelines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41874.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">247</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">4</span> Adaptation to Repeated Eccentric Exercise Assessed by Double to Single Twitch Ratio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damian%20Janecki">Damian Janecki</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Jask%C3%B3lska"> Anna Jaskólska</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Marusiak"> Jarosław Marusiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20Jask%C3%B3lski"> Artur Jaskólski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to assess double to single twitch ratio after two bouts of eccentric exercise of the elbow flexors. Maximal isometric torque, single and double twitch responses and low-frequency fatigue were assessed on the elbow flexors in 19 untrained male volunteers before, immediately after, 24 and 48 hours following two bouts of eccentric exercise consisted of 30 repetitions of lowering a dumbbell adjusted to ~75% of each individual's maximal isometric torque. Maximal isometric torque and electrically evoked responses decreased significantly in all measurements after the first bout of eccentric exercise (P<0.05). In measurements performed at 24 and 48 hours after the second bout both maximal voluntary isometric torque and electrically evoked contractions were significantly higher than in measurements performed after the fist bout (P<0.05). Although low-frequency fatigue significantly increased up to 48 hours after each bout of eccentric exercise, its values at 24 and 48 hours after the second bout were significantly lower than at respective time points after the first bout (P<0.05). Smaller changes in double to single twitch ratio at 24 and 48 hours after the second bout of eccentric exercise reflects repeated bout effect that confers protection against subsequent exercise-induced muscle damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biceps%20brachii" title="biceps brachii">biceps brachii</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=lenghtening%20contractions" title=" lenghtening contractions"> lenghtening contractions</a>, <a href="https://publications.waset.org/abstracts/search?q=repeated%20bout%20effect" title=" repeated bout effect "> repeated bout effect </a> </p> <a href="https://publications.waset.org/abstracts/49190/adaptation-to-repeated-eccentric-exercise-assessed-by-double-to-single-twitch-ratio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49190.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">320</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">3</span> Biomechanical Assessment of Esophageal Elongation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Kozu%C5%84">Marta Kozuń</a>, <a href="https://publications.waset.org/abstracts/search?q=Krystian%20Toczewski"> Krystian Toczewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylwester%20Gerus"> Sylwester Gerus</a>, <a href="https://publications.waset.org/abstracts/search?q=Justyna%20Wolicka"> Justyna Wolicka</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Boberek"> Kamila Boberek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Filipiak"> Jarosław Filipiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Patkowski"> Dariusz Patkowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long gap esophageal atresia is a congenital defect and is a challenge for pediatric surgeons all over the world. There are different surgical techniques in use to treat atresia. One of them is esophageal elongation but the optimal suture placement technique to achieve maximum elongation with low-risk complications is still unknown. The aim of the study was to characterize the process of esophageal elongation from the biomechanical point of view. Esophagi of white Pekin Duck was used as a model based on the size of this animal which is similar to a newborn (2.5-4kg). The specimens were divided into two groups: the control group (CG) and the group with sutures (SG). The esophagi of the control group were mounted in the grips of the MTS Tytron 250 testing machine and tensile test until rupture was performed. The loading speed during the test was 10mm/min. Then the SG group was tested. Each esophagus was cut into two equal parts and that were fused together using surgical sutures. The distance between both esophagus parts was 20mm. Ten both ends were mounted on the same testing machine and the tensile test with the same parameters was conducted. For all specimens, force and elongation were recorded. The biomechanical properties, i.e., the maximal force and maximal elongation, were determined on the basis of force-elongation curves. The maximal elongation was determined at the point of maximal force. The force achieved with the suture group was 10.1N±1.9N and 50.3N±11.6N for the control group. The highest elongation was also obtained for the control group: 18mm±3mm vs. 13.5mm ±2.4mm for the suture group. The presented study expands the knowledge of elongation of esophagi. It is worth emphasizing that the duck esophagus differs from the esophagus of a newborn, i.e., its wall lacks striated muscle cells. This is why the parts of animal esophagi used in the research are may characterized by different biomechanical properties in comparison with newborn tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=long%20gap%20atresia%20treatment" title="long gap atresia treatment">long gap atresia treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=esophageal%20elongation" title=" esophageal elongation"> esophageal elongation</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanical%20properties" title=" biomechanical properties"> biomechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20tissue" title=" soft tissue"> soft tissue</a> </p> <a href="https://publications.waset.org/abstracts/148119/biomechanical-assessment-of-esophageal-elongation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148119.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">100</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">2</span> Analysis of Expression of SP and NOS in the Porcine Nodose Ganglion (NG) Sensory Neurons Supplying Prepyloric Stomach Region after Intragastric Hydrochloric Acid Infusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liliana%20Rytel">Liliana Rytel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Ca%C5%82ka"> Jarosław Całka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the diseases that are very common health problem of modern man is the stomach hyperacidity. It is well known that this pathological state, during which gastric glands secrete too much of hydrochloric acid can be caused due to various factors such as stress, eating habits, alcohol, smoking and some, especially anti-inflammatory drugs. Moreover, hyperacidity is recognized as one of factors leading to development of peptic ulcer disease. Therefore, we analyzed expression of substance P (SP) and neuronal isoform of nitric oxide synthase (nNOS) in the porcine nodose ganglion sensory neurons innervating prepyloric stomach region in physiological state and following intragastric infusion of hydrochloric acid. The study was performed on 8 immature gilts of the Large White Polish breed. All animals were injected retrograde marker Fast Blue (FB) into the anterior prepyloric stomach wall. After injections of FB, pigs were divided into two groups: control (group C; n = 4) and experimental (HCL group, n = 4) and after convalescence period of 23 days, animals of HCL group were subjected to renewed anaesthesia. Then, 0.25 M aqueous solution of hydrochloric acid with a dose of 5 ml/kg body weight was administered intragastrically with use of a stomach tube. On 28th day, all control and HCL pigs were euthanized and bilateral reght (rNG) and left (lNG) were collected. Cryostat sections were processed for double immunofluorescence using anibodies against SP and NOS. Immunofluorescence staining in the even-numbered ganglia nodes showed the presence of FB-positive cells expressing SP (45,9 ± 3,38% in rNG and 60,4 ± 1,71% in lNG), and nNOS (34,9 ± 6,83% in rNG and 49,9 ± 9,32% in lNG). In HCL group increased expression of both SP (54,8 ± 5,34% in rNG and 56,9 ± 3,28 % in lNG) as well as nNOS (54,9 ± 4,45% in rNG and 52,5 ± 2,17 % in lNG) in FB+ perikaria was found. The acquired results suggest that SP and nNOS are neurotransmitters and/ or neuromodulators participating in the sensory regulation of the prepyloric region of porcine stomach function as well as their potential role in development of the stomach inflamatory state. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nNOS" title="nNOS">nNOS</a>, <a href="https://publications.waset.org/abstracts/search?q=nodose%20ganglion" title=" nodose ganglion"> nodose ganglion</a>, <a href="https://publications.waset.org/abstracts/search?q=pig" title=" pig"> pig</a>, <a href="https://publications.waset.org/abstracts/search?q=SP" title=" SP"> SP</a> </p> <a href="https://publications.waset.org/abstracts/42933/analysis-of-expression-of-sp-and-nos-in-the-porcine-nodose-ganglion-ng-sensory-neurons-supplying-prepyloric-stomach-region-after-intragastric-hydrochloric-acid-infusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42933.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">303</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">1</span> Changes in Expression of Galanin in the CSMG Neurons Supplying the Prepyloric Area of the Porcine Stomach Induced by Intragastric Infusion of Hydrochloric Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Palus">Katarzyna Palus</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Ca%C5%82ka"> Jarosław Całka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gastrointestinal disorders, especially acid-related diseases, including peptic and duodenal ulcers, gastroesophageal reflux disease, upper GI bleeding or stress-related mucosal disease, are currently serious health issues encountered very frequently in patients worldwide. However, to date, the response of sympathetic neurons to gastric mucosal injury and local inflammation following hyperacidity is unknown. Thus, the present study was designed to determine possible changes in expression of galanin (GAL) in the CSMG neurons supplying the prepyloric area of the porcine stomach in a physiological state and following experimentally-induced hyperacidity by using combined retrograde tracing and double-labelling immunohistochemistry. The choice of the domestic pig as an experimental model in the present study is not accidental and is justified by the high degree of physiological and anatomical similarity to human digestive system functions. In this experiment ten juvenile female pigs of the Large White Polish breed were used. The animals were divided into two groups: control and animals with hydrochloric acid infusion (HCl). The neuronal retrograde marker Fast Blue (FB) was injected into the anterior prepyloric wall of the stomach of all animals. After 23 days, animals of the HCl-group were reintroduced into a state of general anesthesia and intragastrically given 5 ml/kg of body weight of 0.25 M aqueous solution of hydrochloric acid. On the 28th day, all animals were euthanized. The CSMG complexes were then collected and the CSMG cryostat sections were stained immunocytochemically for GAL and TH (tyrosine hydroxylase). Immunohistochemistry revealed that in the control group 8.40 ± 0.53 % out of 200 FB-positive CSMG neurons contained GAL. In HCl group upregulation of the GAL-IR neurons to 22.52 ± 1.18 % were observed. All GAL-IR neurons in both groups showed the simultaneously TH immunoreactivity. Increase in the expression of GAL in FB-positive neurons of the HCL group may suggest its participation in the protective mechanisms of neurons in different pathological processes, such as gastric hyperacidity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coeliac-superior%20mesenteric%20ganglion%20complex" title="coeliac-superior
