Visceral leishmaniasis related secondary haemophagocytic syndrome: A case report.

Visceral leishmaniasis (VL) is a parasitic disease that can trigger haemophagocytic syndrome (HPS), making its prompt diagnosis crucial. The application of metagenome next-generation sequencing (mNGS) provides a rapid diagnostic approach, particularly for patients with negative bone marrow aspiration results. We present here, a case of a male patient in his early 50s who presented with fever and abdominal pain.

Influence of C18 long chain fatty acids on hydrogen metabolism.

During anaerobic treatment, several microorganisms mediate a series of reactions to convert reduced compounds (electron donors) into methane. Inhibitors such as long chain fatty acids (LCFAs) can affect several anaerobic microbial populations and decrease the treatment efficiency. The effects of three C18 LCFAs on hydrogenotrophic methanogens in a flocculated mixed anaerobic culture were assessed in this study.

Human gastrointestinal sulfotransferases: identification and distribution.

Sulfotransferases (STs) catalyze the sulfation of many structurally diverse molecules. Enzymatic assays and Western blots have been used to identify and characterize STs in the human gastrointestinal tract. Sulfation activities for 2-naphthol, dopamine, estradiol, and dehydroepiandrosterone (DHEA) from 23 donors were measured in cytosol prepared from stomach, duodenum, segments of small intestine, and colon and were compared to levels in human liver cytosol.
