Type 2 diabetes mellitus (DM) is characterized by insulin resistance and pancreatic beta cell dysfunction. In high-risk subjects, the earliest detectable abnormality is insulin resistance in skeletal muscle. Impaired insulin-mediated signaling, gene expression, glycogen synthesis, and accumulation of intramyocellular triglycerides have all been linked with insulin resistance, but no specific de...

High doses of the antioxidant vitamin C prevent the increases in skeletal muscle mitochondrial biogenesis after exercise training. Since exercise training effects rely on the acute stimulus of each exercise bout, we examined whether vitamin C supplementation also attenuates the increases in skeletal muscle metabolic signaling and mitochondrial biogenesis in response to an acute exercise bout. M...

Background The objective of this study was to validate a simple predictive model for survival of patients with advanced cancer. Methods Previous studies with training and validation datasets developed a model predicting survival of patients referred for palliative radiotherapy using three readily available factors: primary cancer site, site of metastases and Karnofsky performance score (KPS)....

l cd in binding (concanavalin A, biotinv lated ricinus communis agglutinin, and biotinylated siiccinylated wheat germ agglutinin (B-SWGA)) was used to detect the glycosylated proteins associated with a residual protein fraction [insoluble in 4% sodium dodecyl sulfate and termed the nuclear residual fraction (NRF)] or with nuclear matrix preparations from normal rat liver, azo dye (3'-MeDAB)-ind...

Heme oxygenase (HO)-1 is a protective antioxidant enzyme that prevents cardiomyocyte apoptosis, for instance, during progressive cardiomyopathy. Here we identify a fundamental aspect of the HO-1 protection mechanism by demonstrating that HO-1 activity in mouse heart stimulates the bigenomic mitochondrial biogenesis program via induction of NF-E2–related factor (Nrf)2 gene expression and nuclear...

To examine the role of three cortical eye fields during internally guided decision-making processes, we recorded neuronal activities in the frontal eye field (FEF), supplementary eye field (SEF), and lateral intraparietal cortex (LIP) using a free-choice delayed saccade task with two synchronized targets. Although the monkeys must perform the task in a time-locked manner, they were free to choo...

The dopaminergic neuron degeneration and loss that occurs in Parkinson's disease (PD) has been tightly linked to mitochondrial dysfunction. Although the aged-related cause of the mitochondrial defect observed in PD patients remains unclear, nuclear genes are of potential importance to mitochondrial function. Human peroxisome proliferator-activated receptor γ coactivator-1alpha (PGC-1α) is a mul...

Introduction The General Clause Theorem Prover (GCTP) was designed as a test bed for semantic search control strategies in theorem proving. It is the unique combination of the Graph Construction (GC) procedure of [Shostak 1976] (which is known to out-perform many (all?) linear format systems), embedding the axioms of equality by the use of the Resolution by Unification and Equality (RUE) and Ne...

Tributyltin (TBT), which has been widely used as an antifouling agent in paints, is a common environmental pollutant. Although the toxicity of high-dose TBT has been extensively reported, the effects of low concentrations of TBT are relatively less well studied. We have previously reported that low-concentration TBT decreases α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type glut...

Lectin binding [concanavalin A, biotinylated ricinus communis agglutinin, and biotinylated succinylated wheat germ agglutinin (B-SWGA)] was used to detect the glycosylated proteins associated with a residual protein fraction [insoluble in 4% sodium dodecyl sulfate and termed the nuclear residual fraction (NRF)] or with nuclear matrix preparations from normal rat liver, azo dye (3'-MeDAB)-induce...
