Prevalence of quitting decision and the impact of increased cigarette prices on the smoking behaviours among the male garment workers in Bangladesh.

Objectives: The prevalence of tobacco use is high in Bangladesh, with a cigarette being the most consumed tobacco product. Taxing tobacco is highly effective for tobacco control, raising costs and encouraging smokers to quit or reduce cigarette consumption. Garment workers are the major group of low-wage earners in Bangladesh.

T-cell engagers: model interrogation as a tool to quantify the interplay of relative affinity and target expression on trimer formation.

T-cell engagers (TCEs) represent a promising therapeutic strategy for various cancers and autoimmune disorders. These bispecific antibodies act as bridges, connecting T-cell receptors (TCRs) to target cells (either malignant or autoreactive) via interactions with specific tumour-associated antigens (TAAs) or autoantigens to form trimeric synapses, or trimers, that co-localise T-cells with target cells and stimulate their cytotoxic function. Bispecific TCEs are expected to exhibit a bell-shaped dose-response curve, with a defined optimal TCE exposure for maximizing trimer formation.

Tungsten-Doped ZnO as an Electron Transport Layer for Perovskite Solar Cells: Enhancing Efficiency and Stability.

This study delves into enhancing the efficiency and stability of perovskite solar cells (PSCs) by optimizing the surface morphologies and optoelectronic properties of the electron transport layer (ETL) using tungsten (W) doping in zinc oxide (ZnO). Through a unique green synthesis process and spin-coating technique, W-doped ZnO films were prepared, exhibiting improved electrical conductivity and reduced interface defects between the ETL and perovskite layers, thus facilitating efficient electron transfer at the interface. High-quality PSCs with superior ETL demonstrated a substantial 30% increase in power conversion efficiency (PCE) compared to those employing pristine ZnO ETL.

Depression and anxiety status among informal caregivers of patients with cancer treated at selected tertiary hospitals in Nepal.

Objective: Cancer is a major cause of death globally, and places a substantial burden on both patients and their caregivers. Frequent stress among caregivers often affects their mental well-being. This study was aimed at assessing anxiety and depression levels among informal caregivers of patients with cancer treated at selected tertiary hospitals in Nepal.

Effect of Reaction Parameters on CO Absorption from Biogas Using CaO Sorbent Prepared from Waste Chicken Eggshell.

This study provides an efficient and straightforward approach to eliminate carbon dioxide (CO) by absorption using a calcium oxide (CaO) sorbent derived from chicken eggshells. The sorbent concentration, stirring speed, and contact time were varied. The optimal condition for CO removal was a 10% calcium hydroxide (Ca(OH)) suspension at 600 rpm with 20 min interaction.
