Purpose: Red blood cells (RBCs) senescence and blood rheology during ultra-endurance running events appear to be impacted differently depending on the race distance. The physiological mechanisms underlying these differences are poorly understood.

Methods: We investigated the effects of three different ultra-trail running races performed in La Reunion Island (Mascareignes, "the 70 km", 70 km/4,000 m D+; Trail Du Bourbon, "the 100 km", 100 km/6,090 m D+; Diagonale des Fous, "the 170 km", 170 km/10,500 m D+) on RBC oxidative stress, RBC senescence and blood rheology in 66 finishers (18 "70 km", 24 "100 km", 24 "170 km").

Food-Drug Interaction (FDI) refers to the phenomenon where food affects the pharmacokinetic or pharmacodynamic characteristics of a drug, significantly altering the drug's absorption rate or absorption extent. These Interactions are considered as a primary determinant in influencing the bioavailability of orally administered drugs within the gastrointestinal tract. The impact of food on drug absorption is complex and multifaceted, potentially involving alterations in gastrointestinal physiology, increases in splanchnic blood flow rates, and shifts in the gut microbiota's composition.

Massive blood loss is the main cause of prehospital trauma-related death, the development of rapid and effective hemostatic materials is imminent. Injectable hydrogels have the advantages of covering irregular bleeding sites and quickly closing the wound. However, its inherent viscosity can easily precipitate tissue adhesion and other complications.

Two newly synthesized ligands, 1-((2-(4-(4-methoxyphenyl)thiazol-2-yl)hydrazono)methyl)naphthalen-2-ol (HL1) and 1-((2-(4-(naphthalen-1-yl)thiazol-2-yl)hydrazono)methyl)naphthalen-2-ol (HL2) were characterized using spectroscopy and single X-ray crystallography. Both belong to triclinic systems with space groups P21/c (HL1) and P-1 (HL2), exhibiting planar structures. Biological assays revealed significant antitumor activity, with HL2 showing significant antitumor activity against HepG2 cells (IC: 3.

Red cell exchange is important to treat acutely ill sickle cell patients, but it is time-consuming. An automated red cell exchange technique using cell separators developed by different manufacturers helps in removal of sickled hemoglobin and improving blood viscosity. The use of these cell separators permits automated red cell exchange to be performed safely and smoothly with the isovolemic hemodilution.
