KAPOPORT, STANLEY I., AND JEANNETTE M. BIDINGER. Eject of stretch on contractility and ionic contents of the sartorius muscle of Rana pipiens. Am. J. Physiol. 226(Z) : 452-457’ 1974.-When sartorius muscles of frogs are soaked in Ringer at room temperature, they gain Na, lose K, and lose contractility with time. These changes are retarded by stretching the muscles to ZO-30Y0 of their rest length...

Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...

The advent of neuroimaging in dental research provides exciting opportunities for relating excitation of trigeminal neurons to human somatosensory perceptions. Cold air sensitivity is one of the most frequent causes of dental discomfort or pain. Up to date, devices capable of delivering controlled cold air in an MR-environment are unavailable for quantitative sensory testing. This study therefo...

this study compared diet and regular coca-cola on enamel erosion in cold and room temperatures.seventy five enamel specimens were prepared and divided into 5 equal groups (n=15) as follows: group 1: regular beverage at room temperature, group 2: regular beverage at refri-gerator temperature, group 3: diet beverage at room and group 4: diet beverage at refrige-rator temperature. the specimens we...
