Elevated Senescence Markers in Developing Trisomy 21 Human Lungs.

Human chromosomal anomalies, notably trisomies, disrupt gene expression, leading to diverse cellular and organ phenotypes. Increased cellular senescence (SEN) and oxidative stress in trisomies have gained recent attention. We assessed SEN, senescence-associated secretory phenotype (SASP) and oxidative stress on trisomy 13, 18, and 21 (T13, T18, T21) human fetal lung tissues and isolated primary human fetal lung fibroblasts.

Unraveling the catalase dynamics: Biophysical and computational insights into co-solutes driven stabilization under extreme pH conditions.

Catalase plays a vital role in eliminating toxic peroxides from the human body and the environment. The versatile applications of this enzyme extend across biotechnological industries and innovative bioremediation approaches. Nonetheless, ensuring enzyme stability is a challenging task.

CFTR mutation is associated with bone differentiation abnormalities in cystic fibrosis.

Background: Cystic Fibrosis-related Bone Disease is an emerging challenge faced by 50 % of adult people with cystic fibrosis (CF). The multifactorial causes of this comorbidity remain elusive. However, congenital bone defects have been observed in animal models with CFTR mutations, suggesting its importance.

Validation of the Working Ability, Location, Intensity, Days of Pain and Dysmenorrhea (WaLIDD) Scale in Arabic-Speaking Young Female Adults.

Background: Dysmenorrhea, characterized by painful menstrual cramps, significantly impacts the well-being of women globally. Despite its prevalence and adverse effects, dysmenorrhea is often underdiagnosed and inadequately treated. This study aims to validate the Arabic version of the Working ability, Location, Intensity, Days of pain, and Dysmenorrhea (WaLIDD) scale among Lebanese female university students aged 18-45.

Knowledge, attitude, and practices related to lead pollution among adolescents and caregivers of young children living near Used Lead Acid Battery (ULAB) recycling sites in Bangladesh: a cross-sectional study.

Background: Lead, a potent neurotoxin, causes irreversible damage to the nervous system, and low- and middle-income countries face huge health and economic productivity losses due to childhood lead exposure. In Bangladesh, informal Used Lead Acid Battery (ULAB) recycling sites are an important source of lead pollution. Little is known about lead awareness among communities exposed to ULAB recycling.
