Background And Aim: In the light of the abundance of various analgesic methods available for analgesia following modified radical mastectomy (MRM) (pharmacological or interventional), we aimed to try a very simple technique using a drug combination (ketamine-bupivacaine) through wound instillation and to compare it to the reputable PECS-II block using the same drug combination. We hypothesized that, with this drug combination, local instillation may achieve a comparable, long lasting, analgesia for almost 48 hours, with less costly, and simple method.

Patients And Methods: Sixty women scheduled to undergo MRM participated in this study.

In recent years, the catalytic activity of scandium triflate Sc(OTf) has attracted significant attention due to its robust Lewis acidity and the oxophilicity of Sc. These features have led to impressive progress in developing diverse organic reactions, including C-C bond formation. The Sc also facilitates single electron transfer in photoinduced reactions either by coordination to an organophotoredox catalyst, which modifies its redox reactivity, or by the formation of a scandium-superoxide anion complex after electron transfer from a light-absorbing redox-active compound.

Sleep disorders and stroke are intricately linked through a complex, bidirectional relationship. Sleep disturbances such as obstructive sleep apnea (OSA), insomnia, and restless legs syndrome (RLS) not only increase the risk of stroke but also frequently emerge as consequences of cerebrovascular events. OSA, in particular, is associated with a two- to three-fold increased risk of incident stroke, primarily through mechanisms involving intermittent hypoxia, systemic inflammation, endothelial dysfunction, and autonomic dysregulation.

National Eye Institute (NEI)-funded randomized controlled trials (RCTs) have significantly shaped the modern landscape of keratoplasty for endothelial disorders. Unlike retrospective studies, RCTs have offered the highest level of clinical evidence and have addressed critical questions related to histocompatibility matching, donor and donor tissue characteristics, donor tissue storage, and operative and postoperative factors supporting postoperative endothelial cell health. These RCTs have in turn directly influenced eye banking and keratoplasty practices.

Background: Transvaginal progesterone is used to aid throughout the luteal phase. Administering a dose of gonadotrophin-releasing-hormone analogues (GnRHa) six days following OPU in GnRH antagonist cycles might cause rise in pituitary gonadotropins (luteinizing hormone (LH) and follicle-stimulating hormone (FSH)), leading to rise in steroid synthesis (estradiol (E2) and progesterone (P)) by the corpora lutea (CL). This work aimed to contrast the effect of lipopolysaccharides (LPS) with adding GnRHa to progesterone P, at day six after ovum pickup versus P alone, on the clinical pregnancy rate.
