Deep ultraviolet Raman spectroscopic analysis of antihistamine drugs in oral fluid for forensic purposes.

Owing to its inherent nondestructive nature, rapid analysis and simplicity, Raman spectroscopy has emerged as a promising tool for forensic analysis of different bodily fluids, particularly oral fluid (OF). Accurate drug identification and quantification are essential for understanding the circumstances surrounding a case, such as whether it involves an overdose fatality, substance abuse, or drug trafficking. This study aims to evaluate the potential of using deep ultraviolet Raman spectroscopy (DUVRS) to detect the antihistamine cetirizine (CTZ) in liquid and solid OF samples.

Emergency contraceptive pill awareness in Bangladesh: missed opportunities in antenatal care and family welfare assistant visits.

Background: Despite high coverage of antenatal care (ANC) and family welfare assistant (FWA) visits, emergency contraceptive pill (ECP) awareness is critically low in Bangladesh. We aim to investigate the missed opportunities in generating ECP awareness through ANC and FWA visit programs; and assess the missed opportunities and sociodemographic discrimination in receiving family planning (FP) counseling during ANC.

Methods: We used data from the nationwide Bangladesh Demographic and Health Survey 2017-18.

Education of household head and maternal healthcare utilization: the case of Bangladesh.

Background: The high maternal mortality ratio in South Asian countries could be attributed to poor maternal healthcare (MHC) utilization. Here household heads (HHs) are the main decision-makers of the households and thus can be key stakeholders in women's MHC uptake. We aim to investigate the role of HHs' education in MHC utilization and explore the educational status of male adolescents who will eventually replace today's HHs in the future.

Coinfection and Clinical Impact of Enterotoxigenic Escherichia coli Harboring Diverse Toxin Variants and Colonization Factors: 2017-2022.

Objectives: The severity of the diarrhea disease is exacerbated by co-infections that involve Enterotoxigenic Escherichia coli (ETEC) and other enteric pathogens, which complicate the diagnosis and treatment. This study explores the prevalence, clinical manifestations, and risk factors of ETEC and its co-infections in Dhaka, Bangladesh.

Methods: The study used data from the Diarrheal Disease Surveillance System at Dhaka Hospital, involving 16,276 patients from 2017-2022.

An analysis of the structural changes of the oxygen evolving complex of Photosystem II in the S and S states revealed by serial femtosecond crystallography.

Photosystem II (PSII) is a unique natural catalyst that converts solar energy into chemical energy using earth abundant elements in water at physiological pH. Understanding the reaction mechanism will aid the design of biomimetic artificial catalysts for efficient solar energy conversion. The MnOCa cluster cycles through five increasingly oxidized intermediates before oxidizing two water molecules into O and releasing protons to the lumen and electrons to drive PSII reactions.
