Article Abstract
The novel corona virus (SARS CoV-2) was first detected on Wuhan, China. After that it spread worldwide and has caused many deaths till now. This virus is also known as novel corona virus because of being newly discovered. Scientifically it is named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has positive-single stranded RNA and several proteins such as spike (S), envelope (E), membrane (M), nucleocapsid (N) and the other helper proteins. On the basis of phylogenic evidence, it is the new member of beta corona viruses and this group of viruses causes respiratory illness in human. This virus is detected in laboratory by using RT-PCR, by which different target gene such as E gene, S gene, N gene and RdRP (ORF1a-ORF1b) etc. are detected. This study was carried out at Mymensingh Medical College from April 2020 to December 2020. Around 65000 samples (nasopharyngeal swab) were tested during this period by three PCR protocols. By Sansure PCR kit N and ORF1a target genes were detected, Basphore's target genes were E and ORF and by Neoplex PCR kit N and RdRp genes were detected. Most of samples were tested by Sansure kit (62500), 2000 samples were screened by Bosphore kit and 500 samples by Neoplex. Among them, 6876(11.0%) samples were positive by Sansure, 120(6.0%) by Bosphore and 66(13.2%) by Neoplex. Among the positive samples, N gene 6188(90.0%) was mostly found by Sansure kit, whereas ORF was 120(100.0%) mostly found by Bosphore.

Hippocampal injury in the Alzheimer's disease (AD) pathological process is region-specific and magnetic resonance imaging (MRI)-based measures of localized hippocampus (HP) atrophy are known to detect region-specific changes associated with clinical AD, but it is unclear whether these measures provide information that is independent of that already provided by measures of total HP volume. Therefore, this study assessed the strength of association between localized HP atrophy measures and AD-related measures including cerebrospinal fluid (CSF) amyloid beta and tau concentrations, and cognitive performance, in statistical models that also included total HP volume as a covariate. A computational technique termed localized components analysis (LoCA) was used to identify 7 independent patterns of HP atrophy among 390 semiautomatically delineated HP from baseline magnetic resonance imaging of participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI).
