An efficient and cost-effective method for disrupting genes in RAW264.7 macrophages using CRISPR-Cas9.

The clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein 9 (Cas9) are widely used for genome editing in cultured cell lines. However, the implementation of genome editing is still challenging due to the complex and often costly multi-step process associated with this technique. Moreover, the efficiency of genome editing varies across cell types, often limiting utility.

Salinity intrusion both in surface and groundwater caused a crisis for safe drinking water in coastal Bangladesh. The situation is even worse for children especially at school. However, information on water services in coastal schools is limited.

Emotion Detection Based on Bangladeshi People's Social Media Response on COVID-19.

The COVID-19 pandemic is still active on a global scale while the virus was first identified in December 2019 in Wuhan, China. As the pandemic continues to affect millions of lives, several countries including Bangladesh have gone into complete lockdown for a second time. During the lockdown periods, people have expressed their experiences, curiosities, and ideas regarding the problems caused by the pandemic in terms of health and socioeconomic issues.

Use of risk scores for predicting new atrial fibrillation after ischemic stroke or transient ischemic attack-A systematic review.

Background: Newly detected atrial fibrillation (NDAF) following an ischemic stroke or transient ischemic attack is often paroxysmal in nature. While challenging to detect, extended electrocardiographic (ECG) monitoring is often used to identify NDAF which has resource implications. Prognostic risk scores have been derived which may stratify the risk of NDAF and inform patient selection for ECG monitoring approaches after ischemic stroke/transient ischemic attack.

Modified Hexagonal Split Ring Resonator Based on an Epsilon-Negative Metamaterial for Triple-Band Satellite Communication.

A triple-band epsilon-negative (ENG) metamaterial based on a split ring resonator (SSR) with a modified hexagonal-shaped metal strip proposed in this study is a new combination of a single slit square resonator and a modified hexagonal-shaped metal strip. The desired unit cell FR-4 (lossy) that was selected as the substrate was 1.6 mm thick.

Impact of community-based first responder development for the management of drowning casualties in rural areas of Bangladesh.

Background: Drowning is the leading cause of childhood death in Bangladesh. In order to minimize the number of casualties Centre for Injury Prevention and Research, Bangladesh (CIPRB) incorporated a 'first responder' program which includes Cardio Pulmonary Resuscitation (CPR), in community based drowning prevention program, . Along with swimming lessons, swimming instructors provide first responder services in the community.

Medical care-seeking behaviours among drowning casualties: Results from a national survey conducted in Bangladesh.

Objective: Despite the high magnitude of drowning, medical care-seeking behaviours among drowning casualties remain unexplored in Bangladesh. This study aimed to explore this behaviour among drowning casualties in Bangladesh.

Methods: A population-based cross-sectional study was conducted using a multi-stage cluster sampling method.

Investigation of sequential outbreaks of Burkholderia cepacia and multidrug-resistant extended spectrum β-lactamase producing Klebsiella species in a West African tertiary hospital neonatal unit: a retrospective genomic analysis.

Background: Sick newborns admitted to neonatal units in low-resource settings are at an increased risk of developing hospital-acquired infections due to poor clinical care practices. Clusters of infection, due to the same species, with a consistent antibiotic resistance profile, and in the same ward over a short period of time might be indicative of an outbreak. We used whole-genome sequencing (WGS) to define the transmission pathways and characterise two distinct outbreaks of neonatal bacteraemia in a west African neonatal unit.

Structure of the capsule and lipopolysaccharide O-antigen from the channel catfish pathogen, Aeromonas hydrophila.

A hypervirulent A. hydrophila (vAh) pathotype has been identified as the etiologic agent responsible for disease outbreaks in farmed carp species and channel catfish (Ictalurus punctatus) in China and the Southeastern United States, respectively. The possible route of infection has previously been unknown; however, virulence is believed to be multifactorial, involving the production/secretion of several virulence factors, including a high molecular weight group 4 capsular polysaccharide.

Settings: The survey was conducted in 39 subdistricts of all 6 districts of the Barisal division, Southern Bangladesh.

Participants: All residents (for a minimum 6 months prior to survey) of the Barisal division, Southern Bangladesh.

Perfect metamaterial absorber with high fractional bandwidth for solar energy harvesting.

A new perfect metamaterial absorber (PMA) with high fractional bandwidth (FBW) is examined and verified for solar energy harvesting. Solar cells based on perfect metamaterial give a chance to increase the efficiency of the system by intensifying the solar electromagnetic wave that incident on the device. The designed structure is mostly offered in the visible frequency range so as to exploit the solar's energy efficiently.

Identification of Subsets of Enteroaggregative Associated with Diarrheal Disease among Under 5 Years of Age Children from Rural Gambia.

Enteroaggregative (EAEC) cause acute and persistent diarrhea, mostly in children worldwide. Outbreaks of diarrhea caused by EAEC have been described, including a large outbreak caused by a Shiga toxin expressing strain. This study investigated the association of EAEC virulence factors with diarrhea in children less than 5 years.

Epidemiology of adulthood drowning deaths in Bangladesh: Findings from a nationwide health and injury survey.

Annual global death due to drowning accounts for 372,000 lives, 90% of which occur in low and middle income countries. Life in Bangladesh exposes adults and children to may water bodies for daily household needs, and as a result drowning is common. In Bangladesh, due to lack of systemic data collection, drowning among adults is unknown; most research is focused on childhood drowning.

Classification of a Hypervirulent Pathotype Responsible for Epidemic Outbreaks in Warm-Water Fishes.

Lineages of hypervirulent (vAh) are the cause of persistent outbreaks of motile septicemia in warm-water fishes worldwide. Over the last decade, this virulent lineage of has resulted in annual losses of millions of tons of farmed carp and catfish in the People's Republic of China and the United States (US). Multiple lines of evidence indicate US catfish and Asian carp isolates of affiliated with sequence type 251 (ST251) share a recent common ancestor.

A sample cell for in situ electric-field-dependent structural characterization and macroscopic strain measurements.

When studying electro-mechanical materials, observing the structural changes during the actuation process is necessary for gaining a complete picture of the structure-property relationship as certain mechanisms may be meta-stable during actuation. In situ diffraction methods offer a powerful and direct means of quantifying the structural contributions to the macroscopic strain of these materials. Here, a sample cell is demonstrated capable of measuring the structural variations of electro-mechanical materials under applied electric potentials up to 10 kV.

Comparative behavior of root pathogens in stems and roots of southeastern Pinus species.

Root diseases are expected to become a greater threat to trees in the future due to accidental pathogen introductions and predicted climate changes, thus there is a need for accurate and efficient pathogenicity tests. For many root pathogens, these tests have been conducted in stems instead of roots. It, however, remains unclear whether stem and root inoculations are comparable for most fungal species.

Complete genome of Staphylococcus aureus Tager 104 provides evidence of its relation to modern systemic hospital-acquired strains.

Background: Staphylococcus aureus (S. aureus) infections range in severity due to expression of certain virulence factors encoded on mobile genetic elements (MGE). As such, characterization of these MGE, as well as single nucleotide polymorphisms, is of high clinical and microbiological importance.
