Activation of protein kinase C (PKC) and elevation of intracellular calcium ion concentration ([Ca++]i) result from phosphatidylinositol biphosphate (PIP2) breakdown. We previously demonstrated that PKC activation inhibits arginine vasopressin (AVP)-induced osmotic water flow in rabbit cortical collecting tubule (CCT) perfused in vitro at 37 degrees C. To estimate the potential significance of ...

European legislation demands that slaughter animals, including poultry, be rendered immediately unconscious and insensible until death occurs through blood loss at slaughter. This study addressed requirements for stunner settings (i.e., voltage, wave oscillation frequency) and response parameters (i.e., applied current, behavior) affecting effective water bath stunning. An inventory of current ...

Studies were designed to examine whether the thin ascending limb of Henle (tALH) decreases its luminal solute concentration by an active or a passive transport process. In all experiments isolated segments of rabbit tALH were perfused in vitro. When tubules were perfused with solutions identical to the bath, active transport of NaCl was excluded by the following: (a) osmolality of the collected...

Manipulating Ag nanowire (AgNW) assembly to tailor the opto-electrical properties and surface morphology could improve the performance of next-generation transparent conductive electrodes. In this paper, we demonstrated a water-bath assisted convective assembly process at the temporary water/alcohol interface for fabricating hierarchical aligned AgNW electrodes. The convection flow plays an imp...

This project is based on the self-tuning fuzzy logic controller, for the design of a temperature control process , the performance of the system should be reliable. The proposed control system combines the advantages of Self Tuning and Fuzzy Logic Control schemes. In order to evaluate the performance of the proposed control system methods, results from simulation of the process are presented. T...

It was suggested that these excluded infants constitute ...

the physician role as a base. There might be perceived sexual gain or exploitation involved (about two-thirds of boundary cases have been such). But it might also involve perceived personal or ªnancial exploitation. (In the cases of boundary violations, we carefully use the word perceived because this is so often contended.) The second range of ethical misconduct is self-serving ªnancial gain o...

Spider silk has exceptional mechanical and biocompatibility properties. The goal of this study was optimization of the mechanical properties of synthetic spider silk thin films made from synthetic forms of MaSp1 and MaSp2, which compose the dragline silk of Nephila clavipes. We increased the mechanical stress of MaSp1 and 2 films solubilized in both HFIP and water by adding glutaraldehyde and t...
