Despite the long history of experimental trials to combat schistosomiasis, it remains a significant burden due to drug resistance and the effectiveness of the standard treatment only against the mature stage, while skipping other early developmental stages thus leading to severe permanent pathological sequelae. Therefore, repurposing a commonly used well-known safe drug would be a wise alternative. We investigated the potential anti-schistosomal drug activity of Daflon® (DAF) against different schistosomal developmental stages.

Serum anti-phenolic glycolipid-I (PGL-I) IgM antibody level is considered an important diagnostic and prognostic marker for leprosy patients. However, there is limited evidence on the role of anti-PGL-I IgM antibody level as early predictive biomarker of subclinical infection among Egyptian household contacts of leprosy patients.

This study assesses the relationship between CSVD (composite and individual features) and all-cause mortality in a large cohort of geriatric outpatients.
Methods: Data from 1305 geriatric outpatients (mean age 78 ± 7; 51 % female) in the Amsterdam Ageing cohort were analysed.
Postpartum mothers and their healthcare providers often face the challenge of limited data regarding the safety of drug therapies during lactation. Pregnancy can lead to sustained weight gain, and obesity can negatively impact both physical and psychological well-being. The introduction of GLP-1 agonists to augment weight loss has become a topic of interest for many postpartum mothers.

In vitro anticancer activity towards different human cancer cells (HCT116, MDA-MB-231 and A549) was assessed using MTT assay. Among all derivatives, 4C- and 6C-spacer derivatives (7 e and 7 f) had the most potent growth inhibitory activities against HCT116 cells with IC values of 39.

In this regard, we created unique hybrid molecules out of diphenyl ether-linked fused pyrans and other heterocycles. The Michael reaction of 4,4'-oxydibenzaldehyde with malononitrile and various active methylene derivatives, as well as enaminone derivatives, produced the matching bis-fused pyrans and fused pyridines, both connected to a diphenyl ether moiety.
