Houmard, Joseph A., Christopher D. Shaw, Matthew S. Hickey, and Charles J. Tanner. Effect of short-term exercise training on insulin-stimulated PI 3-kinase activity in human skeletal muscle. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E1055–E1060, 1999.—The purpose of this study was to determine if the improvement in insulin sensitivity with exercise training is associated with enhanced phosph...

BACKGROUND The accumulation of mutations after long-lasting exposure to a failing combination antiretroviral therapy (cART) is problematic and severely reduces the options for further successful treatments. METHODS We studied patients from the Swiss HIV Cohort Study who failed cART with nucleoside reverse transcriptase inhibitors (NRTIs) and either a ritonavir-boosted PI (PI/r) or a non-nucle...

We developed a new enzymatic method for the assay of inorganic phosphate (Pi) by using sucrose phosphorylase (SP; EC 2.4.1.7) and phosphoglucomutase (PGM; EC 5.4.2.2). Pi is transferred to sucrose by SP, producing alpha-D-glucose 1-phosphate (G1P) and alpha-D-fructose. G1P is transphosphorylated by PGM in the presence of alpha-D-glucose 1,6-bisphosphate to form alpha-D-glucose 6-phosphate, whic...

Sparganosis is a tissue invading helminthiasis infecting intermediate hosts, including humans. Strong immune responses are expected to occur in early phases of infection. Thus, we investigated cytokine expressions in splenic dendritic cells and in sera after experimental infection of mice. In splenic dendritic cells, TNF-α and IL-1β expression peaked at week 1 and week 3 post-infection (PI), re...

The photoinduced hydrogen (or deuterium) detachment reaction of thiophenol (C(6)H(5)SH) or thiophenol-d(1) (C(6)H(5)SD) pumped at 243 nm has been investigated using the H (D) ion velocity map imaging technique. Photodissociation products, corresponding to the two distinct and anisotropic rings observed in the H (or D) ion images, are identified as the two lowest electronic states of phenylthiyl...

AIMS Randomized trial to assess change in left ventricle ejection fraction (LVEF) and myocardial perfusion in patients with acute myocardial infarction (AMI) of anterior wall treated with bone marrow stem cells (BMSCs), compared with control group-from baseline in the acute phase up to 12 months of follow-up. METHODS AND RESULTS Forty-five patients were randomized 2:1 to BMSC group (n= 31) or...

Human proteinase inhibitor 9 (PI-9/serpinB9) and the murine ortholog, serine proteinase inhibitor 6 (SPI-6/serpinb9) are members of a family of intracellular serine proteinase inhibitors (serpins). PI-9 and SPI-6 expression in immune-privileged cells, APCs, and CTLs protects these cells against the actions of granzyme B, and when expressed in tumor cells or virally infected hepatocytes, confers...

A new and very efficient one-pot synthesis, in water, of 6 pi + 6 pi electron zwitterionic benzoquinonemonoimines involves the first examples of transamination reactions in quinonoid chemistry and allows the introduction of functionalities to, and the fine-tuning of the properties of, a large family of molecules with interesting potential, both in supramolecular chemistry and as multidentate li...
