Elevated susceptibility to exogenous seizure triggers and impaired interneuron excitability in a mouse model of Leigh syndrome epilepsy.

Mutations in the NADH dehydrogenase (ubiquinone reductase) iron‑sulfur protein 4 (NDUFS4) gene, which encodes for a key structural subunit of the OXFOS complex I (CI), lead to the most common form of mitochondrial disease in children known as Leigh syndrome (LS). As in other mitochondrial diseases, epileptic seizures constitute one of the most significant clinical features of LS. These seizures are often very difficult to treat and are a sign of poor disease prognosis.

Influences of glycine supplementation during vitrification on the developmental potential of vitrified/warmed immature dromedary camel oocytes.

Oocytes experience detrimental osmotic stress during vitrification and warming procedures because of the osmolality imbalance between the vitrification-warming fluids and the intracellular environment. Cellular osmotic homeostasis can be preserved by glycine, a powerful osmolyte with antioxidant properties. We aimed to examine the influences of supplementing glycine to the vitrification solutions (VS) on the developmental potential of vitrified/warmed immature dromedary camel oocytes following IVM/IVF and in vitro embryo culture (IVC).

The ROX index as a predictor of standard oxygen therapy outcomes in thoracic trauma.

Background: Thoracic trauma is commonplace and accounts for 50-70% of the injuries found in severe trauma. Little information is available in the literature as to timing of endotracheal intubation. The main objective of this study was to assess the accuracy of the ROX index in predicting successful standard oxygen (SO) therapy outcomes, and in pre-empting intubation.
