Searching for effective therapeutic agents‏‎ to ‎‏prevent‏ ‏neurodegeneration ‎is a challenging task due ‎to ‎the growing list of neurodegenerative disorders associated with a multitude of inter-related pathways.‎ The induction and inhibition of several different signaling pathways has been shown to slow down and/or attenuate ‎neurodegeneration and decline in cognition and locomotor function. Among these signaling pathways, a new class of enzymes known as sirtuins or silent information regulators of gene transcription has been shown to play important regulatory roles in the ageing process...

Gyrification index (GI) is an appropriate measure to quantify the complexity of the cerebral cortex. There is, however, no universal agreement on the notion of surface complexity and there are various methods in literature that evaluate different aspects of cortical folding. In this paper, we give two intuitive interpretations on folding quantification based on the magnitude and variation of the mean curvature of the cortical surface. We then present a local spectral analysis of the mean curvature to introduce two local gyrification indices that satisfy our interpretations...

For the last thirty years, ongoing efforts have revolutionized the antiretroviral therapy, which changed human immunodeficiency virus (HIV) infections from terrifying lethal diseases to chronic conditions. However, many challenges, like emergence of drug resistance, limited the scope of activity of currently existing anti-HIV agents. Quite often severe side effects and lifelong dependency are the major concerns of present era. All these issues have compelled the scientists to reconsider and refine the current therapies and also contemplate the pivotal priorities for the developments of novel therapeutic paradigms...

BACKGROUND AND OBJECTIVE: Venetoclax is a selective, B-cell lymphoma-2 inhibitor that has demonstrated clinical efficacy in a variety of hematological malignancies. In vitro data indicated weak cytochrome P450 (CYP) 2C9 inhibition by venetoclax; however, it is not predicted to cause clinically relevant inhibition due to high plasma protein binding. A Phase 1 study was conducted in healthy volunteers to evaluate the effect of venetoclax on warfarin pharmacokinetics. METHODS: Subjects received a single oral dose of 5 mg warfarin on day 1 of both periods 1 and 2, separated by a 14 days washout...

Many neuropsychiatric symptoms that follow traumatic brain injury (TBI), including mood disorders, sleep disturbance, chronic pain, and posttraumatic epilepsy (PTE) are attributable to compromised cortical inhibition. However, the temporal trajectory of cortical inhibition loss and its underlying mechanisms are not known. Using paired-pulse transcranial magnetic stimulation (ppTMS) and immunohistochemistry, we tracked functional and cellular changes of cortical inhibitory network elements after fluid-percussion injury (FPI) in rats...

Skill acquisition capabilities vary substantially from one individual to another. Volumetric brain studies have demonstrated that global volume of several subcortical structures predicts variations in learning outcome in young adults (YA) and older adults (OA). In this study, for the first time, we utilized shape analysis, which offers a more sensitive detection of subregional brain anatomical deformations, to investigate whether subregional anatomy of subcortical structures is associated with training-induced performance improvement on a bimanual task in YA and OA, and whether this association is age-dependent...
