Biophysical responses of lymphocytes to environmental stress
… to fully determine cellular responses to environmental perturbations, and describe a situation in which changes to density and size promote survival under conditions of limited nutrient availability. We first investigate the relationship between cell density, volume, buoyant mass, and …

Heat shock proteins as indicators of environmental stress
… proteins (HSP) can be used as indicators of environmental stress in the mammalian organism Peromyscus leucopus, three doses of each of two chemical stresses, cadmium chloride and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), were given intraperitoneally for 14 days. Proteins extracted from …

How does a butterfly embryo cope with environmental stress?
… downwards trend. This thesis focusses on environmental stress directed at butterfly eggs, using the model systems Pararge aegeria and Bicyclus anynana. Eggs are a vulnerable life stage in which environmental stressors can have a major impact on both survival and development. The majority …

Changes in LDH Activity in Cryptobranchus Due to Imposed Environmental Stress
Lactate deydrogenase (LDH), is the enzyme responsible for the conversion of pyruvate to lactic acid. Its activity in the aquatic salamander, Cryptobranchus alleganiensis alleganiensis was studied. Water oxygen saturation was decreased from 100 to 25 to 10% to produce a state of hypoxia, thereby …

Regulation of Progression through Unperturbed Mitosis and in the Presence of Environmental Stress
… progression through mitosis in the presence of environmental stress like anoxia and hypothermia. So far, the interaction of environmental stress with mitotic regulation has been largely neglected. However, oxygen deprivation leads to a rapid and reversible mitotic arrest. Here, anoxia is shown …
