Down-Regulation of T Cell Function by Heat Shock-Induced Excretory Factor of Leishmania Major
Background: Despite demonstration of molecular and biochemical changes induced by heat shock on Leishmania, the immunological importance of such changes has not been elucidated. Objective: Studying the effect of two excretory factors prepared under heat shock and ambient temperature from Leishmania major on Balb/c splenocytes function. Methods: The parasites were cultured at 25°C and then sub...
متن کاملTemperature regulation of the sphinx moth, Manduca sexta. I. Flight energetics and body temperature during free and tethered flight.
The sphinx moth, Celerio lineata, is thought to vary the rate of heat production in response to different rates of heat loss (Heath & Adams, 1965, 1967). It was proposed that during flight in cold air the attitude of the wings is changed, resulting in increased 'drag', greater flight effort, and greater rates of heat production (Adams, 1969). However, direct evidence has not been presented to s...
متن کاملThe Expression of Human Granulocyte Macrophage Colony Stimulating Factor by Heat-Induction in Escherichia coli
A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...
متن کامل"From freeze with moths": first discovery of a habitat in Andean salars for noctuid moths.
Noctuid moths flutter in the high Andes nights at 4,000 m. s. n. m. Their larvae feed on aerial or underground parts of succulent plants. Many of these species are new to science. Strategies and adaptations of the moths for survival in the high Andes mountains are: a circulatory system that includes an abdominal thoracic countercurrent heat exchanger, and they are insulated from the environment...
متن کاملAllometry of post-flight cooling rates in moths: a comparison with vertebrate homeotherms.
1. The rates of post-flight cooling in 25 saturniid moths of 8 genera ranging in weight from 81 to 2650 mg were measured and compared with cooling rates in sphingids, birds and mammals. 2. The initial and terminal cooling rates of the saturniids did not differ significantly. 3. Large saturniids have relatively smaller thoraxes than small ones. 4. In saturniids the rate of post-flight cooling is...
