Influence of Seasonal Hazards on Water, Sanitation, and Hygiene-Related Behavior and Implications for Cholera Transmission in Bangladesh.

Most cholera outbreaks in Bangladesh are seasonal, peaking in the dry and post-monsoon periods. Therefore, we investigated whether changes in water, sanitation, and hygiene (WASH) behavior in three populations in Bangladesh during the year could help explain why these two periods are particular to cholera transmission. The study used a mixed-method design, including a repeated cross-sectional study, focus group discussions, and key informant interviews.

Alkyne modified purines for assessment of activation of Plasmodium vivax hypnozoites and growth of pre-erythrocytic and erythrocytic stages in Plasmodium spp.

Malaria is a major global health problem which predominantly afflicts developing countries. Although many antimalarial therapies are currently available, the protozoan parasite causing this disease, Plasmodium spp., continues to evade eradication efforts.

Iron pill pneumonitis with reactive lymph nodes.

Iron pill pneumonitis can result from accidental aspiration. It usually presents as a triad of airway inflammation, aspiration, and hemosiderin deposition. We report a case of an elderly woman with chronic cough, infiltrates, and lymphadenopathy on imaging alongside nonnecrotizing granulomas on biopsy diagnosed with iron pill pneumonitis.

Enantioselective Total Synthesis of Cannabinoids-A Route for Analogue Development.

A practical synthetic approach to Δ-tetrahydrocannabinol (1) and cannabidiol (2) that provides scalable access to these natural products and should enable the generation of novel synthetic analogues is reported.
