The current treatment of the disease is not efficient or adequate. Therefore, more efficient interventions are required to diminish the substantial burden of the disease. The present study aimed to assess the potential therapeutic value of bone marrow-derived mesenchymal stem cells (BMSCs) and/or taurine supplementation in CP-induced, using intraperitoneal injection of L-arginine. Forty-five rats were randomly divided into five groups (9 rats each): 1) control group, 2) CP group, 3) CP+BMSCs, 4) CP+Taurine, and 5) CP+BMSCs+Taurine. At the end of the experimental period, the pancreatic tissues were collected, weighed, and prepared for light, electron, and immunohistochemical (α-SMA) microscopic examination. The CP group showed destruction of the pancreatic tissues including fatty degeneration, minimal zymogen granules, and focal degranulation of the rER. Some of the islets degenerated with intense immunoreactivity of α-SMA in the stroma. The groups treated with BMSCs or taurine alone showed improvement of the pancreatic architecture with the presence of some cytoplasmic vacuolation, fewer zymogen granules than the control group, and minimal inflammatory cell infiltrate. The CP+BMSCs+Taurine group showed apparently normal architecture. The combined therapy of both BMSCs and taurine could ameliorate CP progression by suppressing inflammation and fibrosis.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76583569","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}

In the case reported here, the hypoglossal branch of the neuromeningeal trunk of the ascending pharyngeal artery communicated with the posterior inferior cerebellar artery (“type 2 persistent hypoglossal artery variant” of Uchino’s classification), but with a preserved junction with the vertebral artery, which is not hypoplastic (“ascending pharyngeal artery - vertebral artery anastomosis” of Lasjaunias’ description). A review of the literature was performed on the “type 1-2 persistent hypoglossal artery variant” (11 cases) and schematic representations of the different anatomic variants are illustrated.

Costus pictus D Don, belonging to the family Costaceae, commonly called Insulin plant/spiral ginger, is preferred by many in recent days. The current study was carried out to determine the effect of methanolic leaf extract of Costus pictus D Don on the pancreas of diabetic-induced albino Wistar rats. Methanolic extract from C.pictus was prepared by soxhalation. The effect of this extract at the dose of 100 mg and 200 mg/kg bw was studied biochemically on blood glucose and blood insulin levels. Histological and histo-morphological observations were studied on the pancreas after 21 days of treatment. The parameters were compared with diabetic and normal rats. Glucose-lowering effect of the plant extract was observed biochemically in diabetic animals treated with both doses of the extracts. It was observed that the effect was more pronounced with 200 mg/kg BW of the extract. The presence of hyperchromic islet cells, granulated beta cells, increase in diameter of islets and number of beta cells as observed by histological examination and histo-morphometric analysis revealed the pancreatic beta cell regenerative property of Costus pictus D Don.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79016879","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}

In this study, we explored the attitudes, perceptions and preferred learning approaches of undergraduate and postgraduate medical students toward the teaching, facilitation, learning and assessment of neuroanatomy, as well as their perceptions on its relevance in the South African medical curriculum. A total of 299 undergraduate and five postgraduate students from the University of Pretoria participated in this study. We used a multi-method approach in which the undergraduate students completed an anonymous quantitative questionnaire, while the postgraduate students participated in a qualitative focus- group discussion. Undergraduate medical students preferred lecture notes to study from above any other type of literature and mainly used laptop computers as preferred electronic devices in preparation for their assessments. The favourite topic was cranial nerves, and the least popular was histology of the nervous system. Postgraduate students shared their undergraduate neuroanatomy experiences and provided constructive feedback and suggestions to undergraduate students and lecturing staff. Ineffective teaching methods and limited contact time remain factors that contribute to neurophobia in South Africa. Students perceive neuroanatomy as an interesting and important subject in their medical degree. However, changes are needed to modernize neuroanatomy and make it more accessible and student-friendly. The challenge then remains: how do we, as lecturers, modernize neuroanatomy in the medical curriculum to make it contemporary and clinically applicable?","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90374425","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}

Regarding the first point, although the SynDaver® synthetic cadaver is offered as a highfidelity model, there is no proof of this material’s effectiveness in gross anatomy teaching, considering its expensive cost. The letter’s authors stated that students perform better on final exams when they dissect these types of material compared to 3D models and anatomical drawings, but there are no systematic studies about its effectiveness or comparison with other teaching resources. Supporting the synthetic cadaver effectiveness, the authors reference the work of Richardson et al. (2020), who explore this material’s utility and student perception in an undergraduate human anatomy course. Using a systematic study, the authors demonstrated its utility by improving student grades by comparing synthetic cadavers and models with only models, but not with other teaching resources. Another referenced author exposes the tool as a new technologic resource to the study of anatomy with clinical orientation, considering that it is adequate to study larger anatomical structures, different organs, and topography, but they omit the proof of their efficacy (Hecht and Larrazabal, 2018).","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82257554","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}

We study here the association between these grooves and an external index of cross-sectional circularity of the tibia, a biomechanical variable related to mobility. Three Iberian skeletal samples were selected for study, representing the Chalcolithic, Early Modern and Contemporary periods, a time span where a significant decrease in ambulatory activity has been documented in European samples. For each tibia, the circularity index and the presence of vascular grooves were recorded. The Chalcolithic sample presented a higher circularity index compared with the other two samples, indicating higher levels of ambulatory physical activity. It also presented a higher frequency of vascular grooves. The association between the circularity index and the presence of vascular grooves was significant, but considerable overlapping in the index was observed between tibiae with few and several grooves. These grooves are associated to the tibialis anterior muscle, which is activated during the gait cycle but also in what has been called “active rest” postures, and possibly in other nonambulatory activities involving foot hyperdorsiflexion. The age- and sex-related changes in the vascular system could be also important in the interpretation of these grooves. These grooves might be partially related to levels of ambulatory activity, but we conclude that its presence cannot be used alone as a qualitative marker of mobility. Its use as a general indicator of overall lower limb muscle activity should be explored.","PeriodicalId":11978,"journal":{"name":"European journal of anatomy","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80482658","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}

We studied differences on karyometric indices of pinealocytes of the peripheral (cortical) and central (medullary) layers of pineal gland in order to analyze the circadian and seasonal modifications, and establish whether these are indicative of functional differences between proximal, intermediate, and distal portions. Results showed that the total karyometric values of the distal area are clearly higher than those of the other two areas, and in turn those of the intermediate area are also significantly higher than those of the pars proximalis; and also, that there are significant differences between the peripheral and central karyometric indices of all the pineal regions analyzed.
