Genetic diversity and population structure studies of West African sweetpotato [Ipomoea batatas (L.) Lam] collection using DArTseq.

Background: Sweetpotato is a vegetatively propagated crop cultivated worldwide, predominantly in developing countries, valued for its adaptability, short growth cycle, and high productivity per unit land area. In most sub-Saharan African (SSA) countries, it is widely grown by smallholder farmers. Niger, Nigeria, and Benin have a huge diversity of sweetpotato accessions whose potential has not fully been explored to date.

Aflatoxin B1 Contamination Association with the Seed Coat Biochemical Marker Polyphenol in Peanuts Under Intermittent Drought.

Aflatoxin B1 (AFB1) contamination (AC) increases as the severity of drought stress increases in peanuts. Identifying drought-tolerant (DT) genotypes with resistance to colonization and/or infection may aid in developing peanuts resistant to aflatoxin contamination in the semi-arid tropics. The goal of this study is to identify DT genotypes with seed coat biochemical resistance to infestation and aflatoxin contamination.

Appendiceal mucocele as an exceptional cause of ileocecocolic intussusception in adults: a case report.

Background: Intussusception is a rare condition in adults, accounting for 5% of intestinal intussusception and being responsible for approximately 1% of all adult bowel obstructions. Neoplastic origin is the most common etiology of intestinal intussusception in adults, unlike pediatric intussusception, which is usually idiopathic. Intussusception due to the appendiceal mucocele is exceptional, and only a few cases have been reported in the medical literature.
