BACKGROUND: Neonatal infections annually claim lives of 1.4 million neonates worldwide. Until now, there is no ideal diagnostic test for detecting sepsis and thus management of possible sepsis cases often depends on clinical algorithm leading to empirical treatment. This often results in unnecessary...

In this study, the cost of working electrode was reduced greatly by replacing glassy carbon electrode (GCE) with 2B pencil. The pencil lead was modified with carbon nanotubes (CNTs) for simultaneous and quantitative detection of hydroquinone (HQ) and catechol (CT). The surface morphology of CNT-modi...

Ce-doped ZnO/CNT composite thin film was fabricated successfully on soda-lime-silica glass substrate by sol-gel drop coating method. The structure and morphology of nanocrystalline Ce-doped ZnO/CNT thin film were characterized by X-ray Diffraction (XRD), X-ray photo-electron spectroscopy (XPS), Fiel...

The aim of this study was to investigate the effects of dietary Spirulina platensis supplementation on the growth and immunity of Mystus cavasius. Fish were fed on the experimental diets, where the fish meal was replaced with S. platensis meal at 0%, 2.5%, 5.0%, 7.5%, and 10% levels, respectively. T...

ABSTRACT Group B streptococcus (GBS) infection is a leading cause of death among newborns in developed countries. Data on the burden of GBS in Asian countries are lacking. This study aimed to understand (i) the rate of maternal rectovaginal GBS carriage, (ii) the rate of vertical transmission of GBS...

OBJECTIVE: To estimate the risk of early-onset neonatal sepsis among newborns of mothers with chorioamnionitis and/or bacterial colonisation in Dhaka. METHODS: We conducted a cohort study at a maternity centre following 600 mother-newborn pairs. Women with a positive bacterial vaginal culture or pos...

Objectives Some Asian countries have been reluctant to adopt Haemophilus influenzae type b (Hib) conjugate vaccination because of uncertainty over disease burden. We assessed the impact of introduction of Hib conjugate vaccine into the Expanded Program on Immunization in Bangladesh on purulent and l...

A 10-week indoor culture study was done to evaluate the effects of varying C/N ratios on growth performance, body composition, immunity, and haematology of stinging catfish Heteropneustes fossilis cultured in zero-water exchange culture tanks. Biofloc-based tanks with four levels of C/N ratio (12, 1...

Hydrogen bonding in polyurethane (PU) is imposed by molecular parameters. In this study, the effect of structural isomerism of certain monomers on hydrogen bonding of waterborne polyurethane (WBPU) was studied theoretically and experimentally. Two dihydroxybenzene (DHB)-based structural isomers such...

In this study, we have investigated the binding mechanism of two FDA-approved drugs (ivermectin and levosalbutamol) with the spike protein of SARs-CoV-2 using three different computational modeling techniques. Molecular docking results predict that ivermectin shows a large binding affinity for spike...

Detection of pneumococcal carriage by multiple co-colonizing serotypes is important in assessing the benefits of pneumococcal conjugate vaccine (PCV). Various methods differing in sensitivity, cost and technical complexity have been employed to detect multiple serotypes of pneumococcus in respirator...

BACKGROUND: The Aetiology of Neonatal Infection in South Asia (ANISA) study aims to determine the etiology of neonatal infections in 5 population-based sites in Bangladesh, India and Pakistan. METHODS: The main laboratory challenges in ANISA were selection and consistent implementation of laboratory...

BACKGROUND: Group B Streptococcus (GBS) is a predominant cause of early-onset neonatal sepsis globally; however, the impact of this organism on the health of newborns in South Asia is debated, due in part to a paucity of community-based assessments. We estimated the prevalence and serotypes of GBS c...

Objective To estimate the prevalence of maternal colonizers in South Asia and their potential to colonize the umbilicus, an important precondition causing neonatal sepsis. Study design We conducted a cross-sectional study at a maternity center in Dhaka with 1219 pregnant women and a subset of 152 ne...

Direct-write lithography, where a nanoscale tip or a stamp serves as a molecular source, is used widely to fabricate self-assembled monolayers (SAMs), nanometers in size. The spatially narrow deposition of molecules creates a droplet, which then spreads to form an ordered SAM. Currently, the dynamic...

A robust, flexible, and uniform layer of solid-electrolyte interphase (SEI) is known to regulate the dendritic growth of a lithium metal anode during electrodeposition. The underlying mechanism and extent of such regulation are largely unknown. The present Brownian dynamics simulation elucidates the...
