Evidence of ostarine excretion in oral fluid after a single controlled oral administration.

The presence of ostarine, a selective androgen receptor modulator (SARM) in an athlete's urine specimen constitutes one of the most frequent anti-doping rules violation as the drug is listed as a member of the S1.2 class "other anabolic agents" of the World Anti-doping Agency Prohibited List, forbidden in- and out-competition. It is possible to challenge this violation but it is at the charge of the athlete to prove innocence.

del(8p) and TNFRSF10B loss are associated with a poor prognosis and resistance to fludarabine in chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is a heterogeneous disease, the prognosis of which varies according to the cytogenetic group. We characterized a rare chromosomal abnormality (del(8p), deletion of the short arm of chromosome 8) in the context of CLL. By comparing the largest cohort of del(8p) CLL to date (n = 57) with a non-del(8p) cohort (n = 155), del(8p) was significantly associated with a poor prognosis, a shorter time to first treatment, worse overall survival (OS), and a higher risk of Richter transformation.

Corynebacterium ramonii sp. nov., a novel toxigenic member of the Corynebacterium diphtheriae species complex.

The Corynebacterium diphtheriae species complex comprises seven bacterial species, including Corynebacterium ulcerans, a zoonotic pathogen from multiple animal species. In this work, we characterise phenotypically and genotypically isolates belonging to two C. ulcerans lineages.

Case report of a fatal 3-hydroxyphencyclidine intoxication, including blood and hair results.

3-Hydroxyphencyclidine (3-OH-PCP) is a hydroxy derivative of phencyclidine, synthesized in 1978 to investigate the structure-activity relationship of phencyclidine derivates. In vitro studies have shown that 3-OH-PCP, like phencyclidine, acts on the N-methyl-D-aspartate receptor and has a higher affinity for this receptor than phencyclidine. The authors report the case of a 38-year-old man, known for drug addiction, found dead at home with two plastic bags of powders found near his body.
