This study determined the profiles, gross tissue and microbial integrity of cadavers used in South-western Uganda (SWU) medical schools. A cross-sectional study was carried out for three months in anatomy and microbiology laboratories of SWU medical teaching institutions. Ethical approval was obtained, cadavers were proportionately selected and examined grossly, and surface swabs taken for microbial analysis. Data collected was entered into Microsoft Excel, cleaned, and exported to Stata version 17 for analysis. Majority of cadavers were male (68%), adult (96%), blacks (100%), unknown cause of death (96%), obtained as unclaimed bodies (100%) and with no cadaver record tag (96%). Nearly a half (48%) cadavers had disrupted dentition, 68% had poor muscle integrity and 80% with abnormal fat. About 27% cadavers had poor surface microbial integrity among which 62.5% had a mixture of both bacteria and fungi, 25.0% had only fungi while 12.5% had only bacteria. A high number of cadavers had micro-organisms on their surfaces with majority having a mixture of bacteria and fungi. Majority of cadavers had poor gross tissue integrity. Better cadaver preservation methods should be adopted. To advocate for the establishment of cadaver donation policy and programs through which good quality cadavers can be obtained.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"99-111"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This comparative study aimed to examine the differences in PMs morphology between the right and left ventricles, focusing on their number, location, and shape. A total of 38 grossly normal hearts from donated bodies were dissected, and the number, location, and shape of PMs in both ventricles were observed. In this study, the left ventricle predominantly exhibited a single PM with 71.05% on the sternocostal surface and 57.89% on the diaphragmatic surface. The right ventricle showed a higher prevalence of single PM, at 89.47% on the sternocostal surface and 63.16% on the diaphragmatic surface. Broad-based shape of the PM emerged as the predominant variant, constituting 55.26% and 44.73% on the sternocostal and diaphragmatic surfaces of the left ventricle, respectively. In contrast, conical-shaped PM predominated in the right ventricle. Unique findings included \"H\" and \"b\" shaped muscles, conjoint PMs were observed exclusively in the left ventricle, and small papillary projections with direct tendinous cord attachment in the right ventricle. A distinct webbed shaped configuration of PM was exclusively observed in the right ventricle in only one specimen. No significant difference (P=0.84) was noted in muscle bellies between ventricular surfaces. This study emphasizes the complexity and variability in PM morphology, highlighting the importance of a thorough understanding of these structures for cardiothoracic surgeons, radiologists, and cardiologists to enhance interventional techniques.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"44-53"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933809/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-seven male rats (3 baseline, 15 experimental, 9 control) aged three months were recruited with the intervention group receiving 0.5 mg/kg of letrozole daily for 50 days by oral gavage while the control group received normal saline. Their cerebella were harvested for histological processing on days 20, 35, and 50. Photomicrographs were taken and analysed using Fiji ImageJ software. The dendritic spine densities and Purkinje linear densities were coded and analyzed using IBM SPSS Statistics version 25.0. A P-value of ≤0.05 was considered significant. A temporal decline in the Purkinje linear density as well as pyknosis and cytoplasmic eosinophilia was noted in the intervention group (P=0.165). Further, the dendritic spine density of the Purkinje neurons in the intervention group was markedly reduced (P=0.01). The reduction in the linear cell density and the dendritic spine density of the Purkinje cells following letrozole administration may provide an anatomical basis for the functional cerebellar deficits seen in chronic aromatase inhibitor use.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"76-85"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933817/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142543204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The logistical challenge of transporting physical bones complicates the process. The increasing use of image processing techniques in the medical field provides a more efficient and convenient alternative. This study used image processing methods to analyze area ratios and percent porosity of the acetabulum and femoral head, with a statistical evaluation of the relationship between these parameters and age at a 90% confidence level (α=0.10). The dataset comprised images from 167 skeletons including 59 females aged 30 to 88 and 108 males aged 28 to 97. The analysis revealed a significant relationship between percent porosity and age in males, both in the acetabulum and femoral head, with P-values below 0.10 but this relationship was not observed in females. A significant relationship between area ratio and age was found in the femoral head region for both genders but not in the acetabulum.

This review aimed to review the surgical anatomy of the EF, including their embryology and radiology. Although the frontoethmoidal sutures mostly have two foramina passing through them, there are reports of single foramen or multiple, up to six foramina. These foramina provide a passage for the ethmoidal arteries and nerves, branches of ophthalmic arteries and nerves. The surgical guideline \"24-12-6\" is based on the approximate distance between the anterior lacrimal crest, the anterior and posterior ethmoidal arteries, and the optic canal, commonly used to navigate this area. However, some studies from various populations defined different ratios. Embryologically, the EF were formed by the union of intramembranous ossified frontal bones and endochondral ossified ethmoid bones. EF and neurovascular structures can be identified in computed tomography even in the 3 mm sectional intervals. A comprehensive anatomical understanding of EF will help clinicians improve surgical guidelines and ultimately reduce the risk of complications.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"1-7"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933806/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142765578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the accuracy of sex estimation using the nuchal crest is lower than that using other anatomical regions. Furthermore, because of the protruding processes and structurally challenging features characterized by uneven and rough surfaces, there is a lack of metric methods for sex estimation, making quantification challenging. In this study, we aimed to validate a derived metric method for sex estimation by reconstructing the nuchal crest region in three-dimensional (3D) images obtained from computed tomography scans of cranial bones and compare its accuracy with that of the nonmetric method. A total of 648 images were collected, with 100 randomly selected for use in the nonmetric method. We applied our metric method to the remaining 548 images. Our findings showed that the surface area of the nuchal crests was greater in male individuals than in female individuals. The nuchal crest surface area quantified by the metric method increased the accuracy of sex estimation by 48% compared with that by the nonmetric method. Our metric method for sex estimation, which quantifies the nuchal crest surface area using 3D images of the skull, led to a high sex estimation accuracy of 93%. Future studies should focus on proposing and quantifying new measurement methods for areas showing sexual characteristics in the skull that are difficult to measure, thereby enhancing the accuracy and reliability of sex estimation in human skeletal identification across various fields.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"535-542"},"PeriodicalIF":1.4,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11663520/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142456266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta-analysis was done for dimensions of MCA, shapes, patterns and MCA anomalies. Newcastle-Ottawa Scale was used for assessment of literature. Statistical analysis was done using R software using meta package. Thirteen research were combined to determine the proportion of MCA length and pooled proportion was 16.53 cm (15.33 to 17.72 cm); I2=98%; P-value<0.01. Nine studies were combined to determine proportion of MCA diameter and pooled proportion was 2.85 cm (2.52 to 3.17 cm); I2=100%; P-value<0.05. M1 segment mean length is more on left side as compared to right side. Mean length in males (16.57±1.40 cm) is more than females (15.9±1.32 cm). Mean diameter of M1 segment is similar on both sides. Mean diameter in males (3.20±0.09 cm) is higher than females (3.14±0.18 cm). Different branching patterns observed were single trunk, early bifurcation, bifurcation, trifurcation, quadrifurcation and multiple trunks. The most typical MCA branching pattern is bifurcation. The shapes of MCA like straight shaped, U shaped, C shaped, inverted U shaped and S-shaped of M1 segment have been described. Straight MCA is the most common shape. The MCA measurements and branching pattern will assist surgeons in limiting errors in the treatment of cerebral aneurysms and infarcts and providing the best possible result for the patients.
