Background Antimicrobial resistance (AMR) is a significant health problem, especially in low- and middle-income countries. This study aimed to investigate the prevalence and trends of antimicrobial resistance (AMR) and multidrug resistance (MDR) in bacterial infections at a tertiary-care hospital in Dhaka, Bangladesh, and the prevalent pathogens and their resistance profiles.

Abstract Organic dyes are major contributors to industrial wastewater pollution, particularly from the textile sector. Approximately 10–15% of synthetic dyes produced globally are released into wastewater, posing significant environmental risks. In this study, a novel 2-hydroxy-3-methoxyphenyl imino-chitosan (HMPI-chitosan) was chemically synthesized and evaluated as a green biosorbent for methyl orange (MO) removal from contaminated water.

Abstract Water contamination by synthetic dyes poses a serious threat to aquatic ecosystems and human health, thus urgently requiring cost-effective and sustainable remediation strategies. In this research work, Cladophora glomerata algae were pyrolyzed at a slow rate (10°C/min) at 350°C for two hours in order to produce high efficiency value-added biochar and were used for the removal of an azo dye called Eriochrome Black T (EBT) from water through adsorption.
