Healthy plasma lipidomic signatures depend on sex, age, body mass index, and contraceptives but not perceived stress.

Perceived stress is thought to contribute to the pathogenesis of metabolic, vascular, mental, and immune diseases, with different susceptibilities in women and men. The present study investigated if and how perceived stress and/or demographic variables, including sex, age, body mass index, regular prescription drugs, occasional analgesics, or dietary supplements, manifested in plasma lipidomic profiles obtained by targeted and untargeted mass spectrometry analyses. The study included 217 healthy women and 108 healthy men, aged 18-68 yr, who were recruited in a 2:1 female:male ratio to account for women with/without contraceptives.

Calcific tendinitis of gluteus maximus insertion.

Calcific tendinitis, classified as enthesopathy, is a self-limiting disease that rarely involves the tendons of the gluteus maximus. We discuss a 52-year-old woman with a 1-year history of localized, reproducible posterolateral pain of her left hip, which was previously treated with steroid injection to her left greater trochanteric bursa without significant pain relief. Plain radiography and magnetic resonance imaging of the left hip revealed abnormal edema and calcifications at the insertion of the gluteus maximus tendon to the gluteal tuberosity, corresponding to the area of maximal tenderness on examination.

Phylogenomic analysis reveals five independently evolved African forage grass clades in the genus Urochloa.

Background And Aims: The grass genus Urochloa (Brachiaria) sensu lato includes forage crops that are important for beef and dairy industries in tropical and sub-tropical Africa, South America and Oceania/Australia. Economically important species include U. brizantha, U.
