Effects of Sublethal Irradiation on Patterns of Engraftment after Murine Bone Marrow Transplantation
Evaluating ecological safety and conducting pest risk analysis for transgenic crops are vitally important before their commercial planting. The beet armyworm, Spodoptera exigua, a long-distance migratory insect pest, is not a direct target of transgenic Cry1Ac-expressing cotton in China, but nevertheless it has recently become an important pest. Migrants leaving their natal field arrive in othe...
Generation of new cardiomyocytes is critical for cardiac repair following myocardial injury, but which kind of stimuli is most important for cardiomyocyte regeneration is still unclear. Here we explore if apoptotic stimuli, manifested through caspase activation, influences cardiac progenitor up-regulation and cardiomyocyte differentiation. Using mouse embryonic stem cells as a cellular model, w...
the purpose of this study was to investigate the therapeutic effects of propolis on biochemical and microbiological parameters in muscle tissues of carp (cyprinus carpio, linnaeus 1758) exposed to arsenic. a sublethal concentration of arsenic (0.01 ppm) and/or 0.01 ppm propolis were administered to fish for seven days. biochemical parameters [ph, lactic acid, total volatile basic nitrogen (tvb-...
The accuracy and consistency of the delivery of ethanol to cultured cells is important to determine effects on morphologic, biochemical and physiologic alterations. Open and closed chamber systems were evaluated to determine cytotoxic vs sublethal, potentially teratogenic effects on neonatal rat cardiac myocytes. The open system employed a variety of cell culture vessels. Cardiac cells were exp...
Pesticides and other chemicals often have detrimental effects at environmental concentrations. Many amphibian species are particularly threatened because of their susceptibility but also because wetlands are often polluted. Behavioral assessments of toxicity have the advantage of showing sublethal effects but quantitative measures at varied scales of integrations are rarely considered together....
