Follicular fluid (FFl), obtained from 24 women treated with clomiphene/hCG in an in vitro fertilization program, was characterized with respect to steroid hormone levels and oocyte maturation inhibitor (OMI) activity. Three FFl samples apparently were derived from cystic follicles and contained low steroid levels and no OMI activity in an in vitro rat oocyte assay. The remaining 21 follicles contained normal preovulatory steroid levels and mature and generally fertilizable oocytes. In 7 of these follicles the FFl (at 50% concentration) significantly inhibited rat oocyte meiosis, while 14 exerted no OMI activity. The results confirm earlier work on porcine and human FFl, suggesting that the putative OMI activity declines with follicular maturation.

Objective: The orthodontic mini-implant (OMI) failure often occurs due to the accumulation of peri-implantitis bacteria surrounding it, which results in a stable, resistant form of absolute skeletal anchorage during orthodontic treatment. Administering doxycycline may be the solution, but long-term side effects result in antibiotic resistance. Roselle flowers (Hibiscus sabdariffa) possess beneficial active phytochemical substances, which may have potential as an OMI peri-implantitis alternative therapy.

The traditional management of acute coronary syndrome has relied on the identification of ST-segment elevation myocardial infarction (STEMI) as a proxy of acute coronary occlusion. This conflation of STEMI with acute coronary occlusion has historically overshadowed non-ST-segment elevation myocardial infarction (NSTEMI), despite evidence suggesting 25% to 34% of NSTEMI cases may also include acute coronary occlusion. Current limitations in the STEMI/NSTEMI binary framework underscore the need for a revised approach to chest pain and acute coronary syndrome management.

Lysophosphatidylethanolamine (LPE) is a bioactive lipid mediator involved in diverse cellular functions. In this study, we investigated the effects of three LPE species, 1-palmitoyl LPE (16:0 LPE), 1-stearoyl LPE (18:0 LPE), and 1-oleoyl LPE (18:1 LPE) on pre-osteoblast MC3T3-E1 cells. All LPE species stimulated cell proliferation and activated the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) 1/2.

Introduction: Victims of interpersonal violence in sports show various mental health concerns. However, no studies have quantitatively examined their primary complaints, considering psychological symptoms such as denial of self-concept and interpersonal challenges not captured by conventional post-traumatic stress disorder (PTSD). Recently, an association between interpersonal violence victimization and complex PTSD (CPTSD) has been noted in Japanese sports coaching situations, specifically for extracurricular sports activities.
