The following descriptive study aimed to contribute to a better preoperative understanding of hepatic vein anatomy impacting surgeries conducted in South Africa. This research study was conducted on 40 livers from donated bodies of 20 females and 20 males, used for academic purposes in the Department of Human Biology, at the University of Cape Town. The age range was between 33 to 105 years old with an average age of 75. The livers were removed, and the liver tissue was scraped away to expose the hepatic veins from their origin of the inferior vena cava (IVC) to their terminating branching points within the various hepatic segments. All the livers presented all three major hepatic veins, 90.0% of the livers had a common trunk (n = 36), and the remaining 10.0% had no common trunk (n = 4). The major and minor hepatic veins were observed for all the livers. This study found various morphological variations in a South African population that are of clinical significance with a high prevalence of accessory right hepatic veins.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82297291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quadriceps tendon is a commonly used autograft. This study presented, for the first time, the morphometry of the harvestable area of the QT using a simple tracing method. Adult cadavers of South Africans of European Ancestry were carefully dissected to expose the tendon. Then the tendon outline (premarked to enhance visibility) was then traced on a firmly secured wax paper which assumed the curvature of the tendon in situ. The tracing was then scanned (with its inscribed scale bar) and the morphometrics were measured on the digitized images using an imageJ software. The limb length was also measured in order to normalize all the measurements. Despite the observable difference in the surface area of the quadriceps tendon in each individual, there was no significant difference. For the other measurements, there were no side or sex differences except for the straight distal width which is sexually dimorphic. Some paired parameters showed a strong correlation but the correlation between the limb length and other measurements was weak. These data will be useful for pre-operative planning of anterior cruciate ligament reconstruction and will shed more light into the usability of the quadriceps tendon as a graft with respect to healing at the donor site and the return of knee function.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":"57 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81232453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous factors can influence its determination, including the anatomy of the nail apparatus, the structure of the nail plate, and the type and quantity of keratins present. To study the relationship between nail consistency and the expression level of type I keratins, a sample was chosen of 32 individuals in the same age group (49.94 ± 3.38 years), 18 with hard consistency nails and 14 with soft consistency nails, with the same number of individuals for each gender. Two buffers with different concentrations of reducing agent (50mM and 200mM) and two antibodies to various type I keratins were analyzed by immunoblotting. The mean extracted protein concentration at 50mM was significantly higher than the concentration at 200mM (p-value<0.001). The expression level obtained with the AE13 antibody did not vary with gender or nail consistency (p-values≥0.942).

Routine histological procedures were performed on ovarian tissues. Follicle number and diameter of all groups were calculated and evaluated under the light microscope. When primary follicle number and diameters were compared statistically among the groups, there was a remarkably meaningful difference between the EMF group and the control, 20 mg carnosine and EMF+20 mg carnosine groups (p<0.05). There were significant irregularities in the structure of the oocyte and the granulosa cells surrounding the oocyte, especially in the EMF-treated groups. However, the structure of the oocyte and the granulosa cells surrounding the oocyte in the EMF+20 mg carnosine group showed a more regular structure compared to the EMF group. In this study, it can be concluded that the number and diameter of ovarian follicles decreased in rats exposed to electromagnetic field and 20 mg of carnosine may prevent damage caused by EMF.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":"71 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85375287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives were to identify the virtual learning interventions implemented by different medical colleges in India during Covid-19 pandemic periods, and to identify suitable technological intervention for teaching anatomy from the educator’s point of view. A cross sectional study was conducted by convenience sampling method. A differential rating scale questionnaire study was conducted. A hundred participants from the department of anatomy of 100 medical colleges with a minimum of 3 years of experience in teaching in the field were the samples. Faculty other than anatomy department of medical colleges was excluded. Consents were taken from each participant and participant information was shared by email. The teachers were from both from Government and from Private Institutions. For most teachers, the biggest difficulty in implementing online teaching during the initial year of online teaching at 2020 was the unstable online teaching environments, platforms and tools (47%), followed by their unfamiliarity with online teaching techniques, platforms and tools (26%). Further, 17% had problems due to insufficient training and management of online teaching from college.

The study showed that the origins of most internal iliac arteries were located by the lumbar vertebrae 4-5. The mean distance from the origin of the internal iliac artery origin to the sacral promontory was 33.95 ± 3.35 mm (on the left), and 31.70 ± 4.64 mm (on the right). The internal iliac artery always had two big branches – anterior and posterior. A third branch was an ilio-lumbar artery, often seen by 43.33%. The diameters of those internal iliac artery branches were comparable on both sides, and the branches of similar name had a little larger diameter on the left than on the right. The internal iliac artery always has two large anterior and posterior branches; in some cases, it has a third branch called ilio-lumbar artery. The internal iliac artery’s length from its origin to the initial branch division is comparable for both right and left sides. The distance from the internal iliac artery’s origin to the sacral promontory is suggestive for surgeons to find the internal iliac artery after determining the sacral promontory.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":"56 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74456201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alprazolam (Alp) is a member of the BDZs family, commonly prescribed as an antipsychotic and anxiolytic agent. Induction of oxidative stress, impairment of cognitive functions and psychomotor skills, conformational alterations in hemoglobin structure and elevation of liver enzymes are among the side effects reported on the use of alprazolam. Several studies have found that alprazolam could favor hepatotoxicity, whereas other studies contradicted those findings. Bone marrow-derived mesenchymal stem cells (BM-MSCs) have been studied as a novel approach for treatment of liver diseases. The current study was designed to assess the biochemical, histopathological and molecular liver alterations in response to oral administration of alprazolam at a dose of 0.3 mg/kg/day for 4 weeks in adult male albino rats and to evaluate the therapeutic effect of BM-MSCs on the alprazolam- induced alterations. Forty adult male albino rats (Sprague Dawley strain; 170-200 g mean body weight) were used. Liver enzymes were measured, isolation and preparation of BM- MSCs were done, and immunohistochemical staining for alpha smooth muscle actin and FGF2 were assessed. Moreover, histological and ultrastructural liver tissue examination and PCR detection of SOD, TNF-α and mirNA-192 were investigated. Animals exposed to alprazolam developed liver injury characterized by significant increase in TNF-α and significant decrease in SOD and miRNA- 192 expression. Histological findings provided supportive evidence for the biochemical and molecular analyses. Treatment with stem cells caused a significant alleviation of the alprazolam- induced findings. In conclusion, alprazolam was found to induce liver injury and oxidative stress, which were ameliorated by BM-MSCs administration.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":"29 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91268577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
