Improved BM3D image denoising using SSIM-optimized Wiener filter

Image denoising is considered a salient pre-processing step in sophisticated imaging applications. Over the decades, numerous studies have been conducted in denoising. Recently proposed Block matching and 3D (BM3D) filtering added a new dimension to the study of denoising. BM3D is the current state-of-the-art of denoising and is capable of achieving better denoising as compared...

Circulatory white spot syndrome virus in South-West region of Bangladesh from 2014 to 2017: molecular characterization and genetic variation

White Spot Syndrome Virus (WSSV), the etiological agent of White Spot Disease (WSD) is a major impediment for shrimp aquaculture in the worldwide. A critical threshold level of WSSV load in infected shrimp is an important trait for disease manifestation and WSSV transmission in cultured shrimp and subsequently make outbreaks. The present study investigated 120 naturally infected...

The Effect of Zinc Supplementation During Pregnancy on Immune Response to Hib and BCG Vaccines in Bangladesh

An essential role for zinc in development of the fetal immune system has been documented. However, the effect of antenatal zinc supplementation on infants’ postnatal immune response to vaccinations is unknown. The objective of this study was to evaluate the effect of zinc supplementation during pregnancy on immune response to the Bacillus Calmette-Guerin (BCG) vaccine and the...

Hepatitis e virus infection in fulminant hepatitis patients and an apparently healthy population in Bangladesh.

This is the first study comparing hepatitis E virus (HEV) infection in Bangladesh in fulminant hepatitis (FH) patients presumed to have a viral cause and in the apparently healthy population. Sera from 22 FH patients were analyzed for antibodies to hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C and D viruses, and HEV and for hepatitis B surface antigen (HBsAg...
