Ras-related small GTP-binding proteins control a wide range of cellular processes by regulating a variety of effector pathways, including prominent roles in the control of mitogen-activated protein kinase (MAPK) cascades. Although the regulatory role(s) for many Ras family GTPases are well established, the physiological function for the Rit/Rin subfamily(More)
The Rem, Rem2, Rad, and Gem/Kir (RGK) GTPases, comprise a subfamily of small Ras-related GTP-binding proteins, and have been shown to potently inhibit high voltage-activated Ca(2+) channel current following overexpression. Although the molecular mechanisms underlying RGK-mediated Ca(2+) channel regulation remains controversial, recent studies suggest that(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a potent neuropeptide that possesses both neurotrophic and neurodevelopmental effects. Recently, the Rit GTPase was found to be activated by a novel Galpha/cAMP/exchange protein activated by cyclic AMP (Epac)-dependent signaling pathway and required for PACAP-dependent cAMP response(More)

This study describes and applies a random-utility-based multiregional input-output (RUBMZIO) model of production, trade, and travel using Texas data. This model simulates trade patterns of labor and commodities among zones based on different export demands, production technologies, travel modes, and network routing options. The paper also describes the(More)
BACKGROUND Internet interventions for depression have shown less than optimal adherence. This study describes the feasibility trial of a multimodal e-mental health intervention designed to enhance adherence and outcomes for depression. The intervention required frequent brief log-ins for self-monitoring and feedback as well as email and brief telephone(More)
The latency-associated transcript (LAT) is the only herpes simplex virus type 1 (HSV-1) gene that is abundantly transcribed during latency. Plasmids expressing LAT inhibit apoptosis induced by etoposide and ceramide in transiently transfected cells. LAT also inhibits apoptosis in trigeminal ganglia of rabbits and promotes spontaneous reactivation,(More)
alpha-Synuclein has been implicated in the pathogenesis of Parkinson's disease (PD). Previous studies have shown that alpha-synuclein is involved in the regulation of dopamine (DA) metabolism, possibly by down-regulating the expression of tyrosine hydroxylase (TH), the rate-limiting enzyme in DA biosynthesis. In this study, we constructed alpha-synuclein(More)
Computational methods are employed to simulate the interaction of the sea anemone toxin ShK in complex with the voltage-gated potassium channel Kv1.3 from mice. All of the available 20 structures of ShK in the Protein Data Bank were considered for improving the performance of the rigid protein docking of ZDOCK. The traditional and novel binding modes were(More)
The comorbidity of seizures, epilepsy, and attention-deficit-hyperactivity disorder (ADHD) prompted the examination of whether atomoxetine use for ADHD is associated with an increased risk of seizures. Seizures and seizure-related symptoms were reviewed from two independent Eli Lilly and Company databases: the atomoxetine clinical trials database and the(More)
