Assessment of demand for male contraceptives: A multi-country study.

Background: As of 2019, high unmet contraceptive needs in low- and middle-income countries result in nearly half of all pregnancies being unintended. Additional male contraceptive options could help, but gaps remain in assessing demand for them. As the development of novel male contraceptives progresses, addressing these gaps would help inform policy and scientific direction.

Island biogeography and human practices drive ecological connectivity in mosquito species richness in the Lakshadweep Archipelago.

Mosquitoes are globally distributed and adapted to a broad range of environmental conditions. As obligatory hosts of many infectious pathogens, mosquito abundance and distribution are primarily determined by the presence and quality of larval habitats. To understand the dynamics and productivity of larval habitats in changing island environments, we conducted a four-month mosquito survey across ten inhabited islands in the Lakshadweep archipelago.

Synthesis of PHB by recombinant E. coli harboring an approximately 5 kb genomic DNA fragment from Streptomyces aureofaciens NRRL 2209.

An approximately 5.0 kb Sau3A I genomic DNA fragment from Streptomyces aureofaciens NRRL 2209 was cloned in a plasmid vector and introduced into Escherichia coli. The recombinant E.
