Tyrosine phosphorylation of lactate dehydrogenase A is important for NADH/NAD(+) redox homeostasis in cancer cells.The Warburg effect describes an increase in aerobic glycolysis and enhanced lactate production in cancer cells. Lactate dehydrogenase A (LDH-A) regulates the last step of glycolysis that generates lactate and permits the regeneration of NAD(+). LDH-A gene expression is believed to be upregulated by both HIF and Myc in cancer cells to achieve increased lactate production. However, how oncogenic signals activate LDH-A to regulate cancer cell metabolism remains unclear. We found that the oncogenic ...201121969607
antibody response against trichinella spiralis in experimentally infected rats is dose dependent.abstract: domestic pigs are the main representatives of the domestic cycle of trichinella spiralis that play a role in transmission to humans. in europe, backyard pigs of small household farms are the most important risks for humans to obtain trichinellosis. rats might play a role in the transmission of trichinella spiralis from domestic to sylvatic animals and vice versa. in order to be able to investigate the role of wild rats in the epidemiology of t. spiralis in the netherlands, we studied t ...201122129040
clinically plausible hyperventilation does not exert adverse hemodynamic effects during cpr but markedly reduces end-tidal pco(2).aims: ventilation at high respiratory rates is considered detrimental during cpr because it may increase intrathoracic pressure limiting venous return and forward blood flow generation. we examined whether ventilation at high, yet clinically plausible, tidal volumes could also be detrimental, and further examined effects on end-tidal pco(2) (p(et)co(2)). methods: sixteen domestic pigs were randomized to one of four ventilatory patterns representing two levels of respiratory rate (min(-1)) and tw ...201121854734
improving microcirculation with therapeutic intrathoracic pressure regulation in a porcine model of hemorrhage.intrathoracic pressure regulation (ipr) has been used to treat hypotension and states of hypoperfusion by providing positive pressure ventilation during inspiration followed by augmentation of negative intrathoracic pressure during expiration. this therapy augments cardiac output and lowers intracranial pressure, thereby providing greater circulation to the heart and brain. the effects of ipr on microcirculation remain unknown.201122208172

Temperature-controlled two-wavelength laser soldering of tissues.Laser tissue soldering is a method for bonding of incisions in tissues. A biological solder is spread over the cut, laser radiation heats the solder and the underlying cut edges and the incision is bonded. This method offers many advantages over conventional techniques (e.g., sutures). Past researches have shown that laser soldering, using a single laser, does not provide sufficient strength for bonding of cuts in thick (>1?mm) tissues. This study introduces a novel method for laser soldering of ...201122006733
The evolutionary importance of cell ratio between notochordal and nucleus pulposus cells: an experimental 3-D co-culture study.INTRODUCTION: Notochordal cells and nucleus pulposus cells are co-existing in the intervertebral disc at various ratios among different mammalians. This fact rises the question about the interactions and the evolutionary relevance of this phenomenon. It has been described that these relatively large notochordal cells are mainly dominant in early lifetime of all vertebrates and then differences occur with ageing. Human, cattle, sheep, and goat lose the cells with age, wherea ...201121953383
