Guinea pig left atria were suspended in a tissue bath of normal Krebs-Henseleit solution which was aerated with 95% O$\sb2$/5% CO$\sb2$ and maintained at 27$\sp\circ$C. The atria were attached to a force transducer and ...

Two peaks consistently arise near 1.3 ppm in $\sp1$H NMR spectroscopic studies of fatiguing skeletal muscles. They are typically 15-20 Hz apart at 300 MHz. Known resonances in this region include lactate, alanine, threonine, ...

In this study we show that chronic exercise leads to alterations in hemodynamic variables in the rat motor cerebral cortex. To accomplish this, we have performed functional imaging experiments in groups of rats allowed ...

In this thesis, the electron paramagnetic resonance (EPR) methods for simultaneous measurement of intra- and extracellular concentration of oxygen ( (O$\sb2$)) in viable cells have been developed.

The vestibular-ocular reflex (VOR) is a plastic system found in vertebrates which produces eye rotations that compensate for head rotations. Simultaneous motion and vision are thus possible since the reflex keeps vision ...
