There is a strong correlation of stature with hand dimensions and if either of the measurements is known, the other can be calculated. With this objective, the present study was designed to correlate the hand dimensions with stature of an individual and to record the standard deviation in the estimation of stature.\u0000\u0000Methodology\u0000This cross-sectional study was conducted amongst 1000 participants (500 male and 500 female) of ESIC Institute Gulbarga over a period of 14 months. Hand dimensions along with stature and weight were measured. Linear regression coefficient was calculated.\u0000\u0000Results\u0000Mean stature was 161.88 cm. Mean hand length was 18.11 cm on right side and 18.10 cm on left side. Mean hand breadth was 9.91 cm on right side and 9.83 cm on left side.\u0000\u0000Conclusion\u0000Highly significant difference in right and left side mean hand length and breadth measurements was observed. Also observed was a strong positive statistically significant correlation between height and hand dimensions. This data might be useful for forensic, epidemiological and anthropometric studies where stature determination is of utmost importance.","PeriodicalId":331883,"journal":{"name":"International Journal of Human Anatomy","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128217435","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}

Oligodendrocyte proliferation and differentiation is regulated by Wnt signaling pathway, at various stages. However, different study groups have described controversial conclusions about the effect of Wnt on oligodendrocytes precursor cells (OPCs) development. Initially it has been proposed that Wnt pathway negatively regulates the OPCs proliferation and differentiation but recently some studies have described that Wnt promotes the differentiation of OPCs. After carefully reviewing the literature, we believe that Wnt play multiple roles in OPCs differentiation and its function is time (stage) and dose sensitive. Low to moderate activation of Wnt promotes OPC development, while too much or too low is inhibitory. Current evidences also suggested that in early developmental stages, Wnt inhibits the OPCs formation from neural progenitors and differentiation into immature oligodendrocytes. But in late stages Wnt plays promoting role in differentiation and maturation of oligodendrocytes. This review summarized the updated information regarding the critical role of Wnt signaling cascade in proliferation and differentiation of OPCs.","PeriodicalId":331883,"journal":{"name":"International Journal of Human Anatomy","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125839843","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}

Abdelfattah","doi":"10.14302/ISSN.2577-2279.IJHA-18-2384","DOIUrl":"https://doi.org/10.14302/ISSN.2577-2279.IJHA-18-2384","url":null,"abstract":"Background: Oral ingestion of zinc oxide nanoparticles (ZnONPs) may lead to serious liver injury. Vitamin E (VE) is an important antioxidant factor that can reduce such damage. Aim: This study aimed to evaluate the possible changes that could take place in the liver of adult male albino rats after oral ingestion of ZnONPs and elucidate the potential protective role of VE against such damage. Material and Methods: Forty eight male albino rats were divided into four groups of 12 animals each. Group (1) served as control group and received normal saline. Group (2) “VE-treated” received 100 mg/kg/day of VE dissolved in normal saline by oral gavage for 21 days. Group (3) “ZnONPs-treated” received a daily dose of ZnONPs dispersed in the fresh sterilized physiological saline solution 1mg/kg for 5 constitutive days. Group (4) “concomitant ZnONPs and VE-treated” was pretreated with VE 100 mg/kg/day for 14 days followed by the same dose of ZnONPs as in group (3) for 5 days. The extent of hepatic damage was evaluated by histological and immunohistochemical examination of liver samples and serological analysis of liver enzymes. Results: Body weights and liver weights showed very highly significant decrease (P <0.001) in the ZnONPs-treated group. The histological results in ZnONPs-treated group revealed congested dilated central veins and blood sinusoids, loss of normal arrangement of hepatocytes and most of hepatocytes showed marked vacuolated cytoplasm with darkly stained nuclei. Portal area affection was in the form of congested dilated portal veins with bile duct hyperplasia and cellular infiltration. There was an increase in the mount of blue stained collagen fibers around central veins together with strong positive reaction for Caspase 3 in ZnONPs-treated group. Similarly biochemical analysis indicated that the levels of serum aminotransferase (AST &ALT) significantly increased in ZnONPs-treated group when compared with other groups. Rats pretreated with VE showed improvement of the histological findings and biochemical parameters. Conclusion: Ingestion of ZnONPs could be associated with serious liver affection and pretreatment with VE is suggested to induce some improvement of such deleterious changes.","PeriodicalId":331883,"journal":{"name":"International Journal of Human Anatomy","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115783336","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}

Its structure differs in newborns than in adults in some aspects. Such differences should be clear for both health and family members. Moreover, the anatomy and embryology of fetal skull take a little attention in the previous literature and textbooks. Therefore, this short review aimed to clarify some aspects of anatomy and clinical importance of cranial vault features in newborns. The newborn vault is formed of multiple separate flat bones connected by fibrous tissues with wide soft gaps called fontanelles. Development of bones of skull vault is closely correlated with the expanding growth of the underlying brain. Such brain shouldn't be struggled by continuous tightening of the newborns' vault. Also, the newborn skull could be affected even by a fixed sleeping position.","PeriodicalId":331883,"journal":{"name":"International Journal of Human Anatomy","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134109322","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}
