Stereospecificity of some invertebrate lactic dehydrogenases
It has been assumed that only among unicellular organisms did nicotinamide adenine dinucleotide (NAD)-linked lactic dehydrogenases occur. All higher animals were thought to possess Lr-specific lactic dehydrogenases. It was ...
An electron microscope study of the endometrium of the rat during delayed implantation
The luminal and glandular epithelia of the uterus of the rat during delayed implantation have been studied with the electron microscope, and the fine structure of these tissues has been described in detail. Light microscope ...
Responses of Littorina irrorata to temperature and salinity variations
Experiments were conducted to determine the survivability of Littorina irrorata and L. lineolata under various conditions of water temperature and salinity, and to determine the sodium and potassium ion concentrations in ...
The chloride cell of Cyprinodon variegatus: cytochemical studies on a cell specialized for electrolyte transport
Cells specialized for high levels of electrolyte transport characteristically possess amplified plasmalemmas which effectively increase the exposure of the cell's surface to extracellular spaces. Of particular interest is ...
Temperature regulation and metabolic rhythms in populations of the house sparrow Passer domesticus
This study was an attempt to correlate the influences of the environmental stresses of high ambient temperatures and high humidities on selected physiological properties related to temperature regula-tion in the house ...
