The Prevalence of Vitamin D Deficiency and Associated Factors Among Subfertile Women: An Initial Experience From Northern Sri Lanka.

Subfertility is a global burden. Low vitamin D status has been associated with an increased risk for subfertility. Even though the prevalence of vitamin D deficiency is very high among women in Sri Lanka, not much importance is given to addressing the issue, especially among subfertile women.

Review of Transition Metal Chalcogenides and Halides as Electrode Materials for Thermal Batteries and Secondary Energy Storage Systems.

Transition metal chalcogenides and halides (TMCs and TMHs) have been extensively used and reported as electrode materials in diverse primary and secondary batteries. This review summarizes the suitability of TMCs and TMHs as electrode materials focusing on thermal batteries (utilized for defense applications) and energy storage systems like mono- and multivalent rechargeable batteries. The report also identifies the specific physicochemical properties that need to be achieved for the same materials to be employed as cathode materials in thermal batteries and anode materials in monovalent rechargeable systems.

Synthesis and antibacterial activity of 2-benzylidene-3-oxobutanamide derivatives against resistant pathogens.

Antibiotic resistance evolves naturally through random mutation. Resistance to antimicrobials is an urgent public health crisis that requires coordinated global action. The ESKAPE bacteria (, , , , , and species) are primarily responsible for the rise in resistant pathogens.
