A case report on weak subgroup of A: A.

A end is a weak subgroup of Blood group A, found rarely in general population, not detected by routine forward and reverse blood grouping, detected by Adsorption/Elution technique along with saliva testing for A, B and H antigens. Although it is subgroup of A but it lacks A antigen in saliva and contains only H antigen. A 25y/M was accepted for blood donation and showed weak/mf reaction with anti-A in forward grouping.

A Study of A1 and A2 Subtypes Among Whole-Blood Donors With Blood Groups A and AB at the Blood Center of a Tertiary Care Institute in Chhattisgarh.

Introduction: The ABO blood group shows various subtypes due to the heterogeneity of A and B alleles. The frequency of these subtypes varies in different populations. Studies related to the frequency of subtypes of blood groups A and AB are lacking in this region.

Age and Gender Estimation Using the Osseous Microanatomy: Original Research.

Aim: This study was performed with the idea of assessing age and gender utilizing differences in osseous microanatomy in human jawbones.

Materials And Methods: The study was conducted retrospectively among human jawbone samples. Various morphometric assessments such as trabecular width, marrow space, and their corelation were studied.

Analysis of marine heatwaves over the Bay of Bengal during 1982-2021.

Anomalous increase in sea surface temperature and its impact on natural ecosystems greatly interests the research community. Here we investigate the causes, impacts, and trends of marine heat wave (MHW) events in the Bay of Bengal (BoB) from 1982 to 2021. A total of 107 MHW events have been isolated (> 90th percentile threshold) in this Indian Ocean region, and their variation in intensity, duration, and frequency has been investigated.
