Selenium (Se) has an enzymatic structure that mediates its antioxidant activities. This study aimed to assess the GA3 toxicity on pre and postnatal ovarian development and to investigate the protective effect of Se against GA3 toxicity in albino rats. Two experiments were conducted in this study (n=24 rats for each): the first was performed on pregnant female rats and the second on prepubertal females (4 weeks old). Rats were divided into Group I (controls: Ia, negative and Ib, positive rats received sodium selenite 0.3 mg/kg/body weight); Group II (GA3-treated, the rats received 55 mg/kg, 1/100 of lethal dose 50); and Group III (the rats were cotreated with GA3 plus Se). Treatments in the first experiment began at gestational day 7 until postnatal day 4, while in the second experiment, treatments lasted two weeks. All hormonal levels were decreased in pre and postnatal GA3 rats' exposure. Histological examination of GA3-treated prenatal rats showed disturbance in ovarian development as shown by ovigerous cords with germ cell breakdown. Meanwhile, multiple histopathological and developmental changes occur in all stages of the ovarian follicles in postnatal rats. In both developmental ages, there was collagen deposition with decreased proliferative marker and androgen receptor expressions, which was confirmed by a decrease in the morphometric measures of the ovarian follicles. All biochemical, immunostaining, and histological results were improved after Se co-administration due to its antioxidant activity against GA3 toxicity.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802224","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}

Morphometric analysis of the scapula has been proposed as a tool for preventing injuries to the suprascapular nerve. The present investigation aimed to determine the safe distances for approaching the suprascapular nerve at the level of the scapular notch (SPN) and spinoglenoid notch, in addition to establishing its relationship with the type of SPN and with two scapular dimensions: major longitudinal axis (MLA) and major transverse axis (MTA). For this purpose, a descriptive-correlative, quantitative, non-experimental and transversal study was carried out, in which 82 dry scapulae from adult individuals of Chilean origin were investigated. The main results of this study found that prevalences were highest for SPNs types II (36.2%), I (29.3%), and III (26.0%), with average distances that were considered safe in all types of SPNs. Furthermore, there was a positive correlation, with P<0.05, between the MTA (r=0.526; r=0.634), MLA (r=0.284) and the safe distances for the suprascapular nerve at the level of the SPN and incisura spinoglenoid of the scapulae studied. Scapular dimensions such as the MTA and the MLA could, therefore, be used to predict a safe zone for the suprascapular nerve, potentially contributing to a reduction in the current rate of injury of the suprascapular nerve in surgical procedures involving the deltoid and scapular regions.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"54-60"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933811/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646779","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 focus was on axillary artery branches in relation to the coracoid process and the documentation of anatomical variations in this area. Significant findings include the categorization of thoracoacromial artery variations and the identification of acromial and clavicular branches as variable. A key measurement was mean distance between the thoracoacromial artery and tip of the coracoid process (31.89 mm). These findings offer valuable insight into the spatial relationships of these structures. The study provides important information on the vascular anatomy surrounding the coracoid process. Recognizing these anatomical variations is essential for planning safer and more effective shoulder surgeries, such as coracoclavicular stabilization and subcoracoid decompression.

The iliohypogastric nerve was absent in 2 cases (8.3%). In the type I pattern, in 1 case (4.2%), the common trunk descends anteriorly to the iliac vessels from the iliolumbar vessels. In 4 cases (16.7%), the double ilioinguinal nerve with different branch patterns and retroperitoneal courses was observed. In 1 single nerve case (4.2%), the ilioinguinal nerve descends anterior to the iliac vessels from the iliolumbar vessels.

Also, nanoparticle (NP) drugs can better affect the target tissue in various diseases. Therefore, the aim of this study was surveying the effect of rosuvastatin (RZV) coated by nano-chitosan in an Alzheimer's (Alz) induced model of rats. We examined learning, memory, and hippocampal amyloid plaques and evaluate expression levels of calbindin, doublecortin (DCX), NeuroD1, neuronal nuclei (NeuN), and neurofilament. Forty rats were randomly divided into five various groups. AD was induced by injecting bilaterally with 1 μl of amyloid beta (Aβ) into the hippocampus. After confirmation of AD, RZV, or NP, or RZV+NP were administered gavage orally daily in rats for 30 days. Induction of AD significantly raised Aβ plaques and dead cells compared to the control group. Results of Morris water maze in the test day indicated that Alz+NP+RZV group significantly reduced escape latency and travelled distance, also significantly increased spending time compared to the Alz group (P<0.05). RZV significantly decreased Aβ plaque percentage and the number of apoptotic cells compared to the Alz group (P<0.05). In addition, NeuN and neurofilament protein expression and calbindin, DCX, and NeuroD1 genes expression increased in Alz+RZV and Alz+RZV+NP compared to the Alz group. RZV coated by nano-chitosan has good potential for reducing Aβ plaques and dead cells, increasing brain NeuN and neurofilament proteins and calbindin, DCX, and NeuroD1 genes, and improving learning and memory in Alz rats.","PeriodicalId":7831,"journal":{"name":"Anatomy & Cell Biology","volume":" ","pages":"61-75"},"PeriodicalIF":1.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11933804/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363477","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}
