Magnetohydrodynamic bioconvective flow of Williamson nanofluid containing gyrotactic microorganisms subjected to thermal radiation and Newtonian conditions.

Magnetohydrodynamic (MHD) bioconvective flow of Williamson nanomaterial in frame of gyrotactic microorganisms is addressed. Nanomaterial characterizes gyrotactic microorganism. Bioconvection is generated by buoyancy forces in the communication of nanoparticles and motile microorganisms.

Regional Influences on Nutritional Iodine Status of Pregnant Women in Pakistan.

Background: Pregnant women are particularly vulnerable to iodine deficiency. Considering the rural-urban disparities in nutritional status in Pakistan, this study aimed to assess regional influences on nutritional iodine status of pregnant women in Pakistan.

Methods: Data were collected from 1246 pregnant women in all trimesters of pregnancy who visited antenatal clinics for routine checkups in five Khyber Pakhtunkhwa province districts.
