abstract background: exercise could change the immune system. it is illustrated that abnormal environments are the primary source of physiological stresses which can disarrange the function of immune system. the purpose of this study was to investigate the effects of high volume exercise (hve) in hypoxia and normoxia conduction on the immune system response in selected inactive men. materials a...

BACKGROUND The mouse is increasingly used in biomedical research, notably in behavioral neurosciences for the development of tests or models of pain. Our goal was to provide the scientific community with an outstanding tool that allows the determination of psychophysical descriptors of a nociceptive reaction, which are inaccessible with conventional methods: namely the true threshold, true late...

Dilute alloys of rare earths have played a vital role in understanding magnetic phenomena. Here, we model the ground state dilute 4f rare-earth impurities light metals. When subshells are open (but not half-filled), spin-orbit coupling imprints rotational charge current conduction electrons around atoms. The sign and amplitude oscillate similar to RKKY spin polarization. We compute observable e...

Atrial, His bundle (H), and ventricular electrograms were recorded by an electrode catheter in unanesthetized man. Conduction time through the atrioventricular (A-V) conduction system was subdivided into A-V nodal (A-H interval) and ventricular specialized conduction system (H-V interval). The right atrium was driven at a constant rate and the pattern of A-V conduction of premature atrial test ...

Patterns of ventriculoatrial conduction have been used to distinguish retrograde conduction over an accessory atrioventricular pathway from that over the normal atrioventricular conduction system. Ventriculoatrial conduction at a constant interval during incremental ventricular pacing and during progressive prematurity of ventricular extrastimuli has been considered characteristic of conduction...

Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...

The deterioration of the performance of a cross flow heat exchanger with condensation due to the longitudinal conduction was investigated. For a relatively small change of wall temperature along the flow directions which was shown to be common in many applications, the energy equations were solved numerically. An iterative method was used to solve the resulting equations of the finite differenc...
