chymotrypsin/fever

Muscle atrophy in a number of acute wasting conditions is associated with an increased activity and expression of the ubiquitin-proteasome proteolytic pathway. Although different initiators are involved, it is possible that the intracellular signalling events leading to upregulation of this pathway

Heat treatment of human erythrocytes led to increased passive cation permeability, followed by haemolysis. K+ leakage was linear up to a loss of about 80% in the temperature range 46-54 degrees C. Kinetic analysis of the results revealed an activation energy of 246 kJ/mol, implicating a transition

Swine fever is conceived as a disorder of the enzyme systems, that are controled by serine proteases. The virus is replicated in the cells of the lymphomycoid complex, whereby the production of a chymotrypsin is induced. In swine fever the lymphatic glands and the lymph flow are increased. Fifteen

After female mosquitoes ingest blood from vertebrate hosts, exopeptidases and endopeptidases are required for digesting blood proteins in the midgut into amino acids, which female mosquitoes use to build yolk proteins. These proteases are not always present in the midgut, and their diverse

Sera from patients with recent streptococcal infection or non-suppurative sequelae exhibit with variable frequency a precipitin reaction in agar gel with a partially purified streptococcal antigen which has been shown previously to be immunologically related to human heart tissue. This precipitin

Further studies on fever production by injection of leukocyte extracts or cell-free supernatant fluids from peritoneal exudates in rabbits are reported. Granulocytes collected from peripheral blood or from pleural exudates contain a heat-labile pyrogenic substance. The material in extracts of

Simian hemorrhagic fever virus (SHFV) causes a severe and almost uniformly fatal viral hemorrhagic fever in Asian macaques but is thought to be nonpathogenic for humans. To date, the SHFV life cycle is almost completely uncharacterized on the molecular level. Here, we describe the first steps of the

Aedes aegypti utilizes blood for energy production, egg maturation and replenishment of maternal reserves. The principle midgut enzymes responsible for bloodmeal digestion are endoproteolytic serine-type proteases within the S1.A subfamily. While there are hundreds of serine protease-like genes in

Salivary gland homogenates and oil-induced saliva of the mosquito Aedes aegypti dilate the rabbit aortic ring and contract the guinea pig ileum. The vasodilatory activity is endothelium-dependent, heat-stable, sensitive to both trypsin and chymotrypsin treatments, and both smooth muscle activities

The effect of temperature on protein metabolism of C2C12 myotubes was investigated in order to estimate the potential effect of fever on muscle catabolism. The half-life of long-lived proteins in C2C12 myotubes was significantly (13%) shorter when incubated at 40 degrees C than at 37 degrees. The

Report on two babies, 5 and 6 months old with severe salt depletion were admitted to our hospital with fever and gastro-enteritis. One of them failed to thrive despite normal nutrition, the other one had a protracted gastro-enteritis. Both of them had a great loss of weight, a strong dehydration and

The blood and urine of mice and rats infected with Babesia rodhaini contain substances which stimulate the isolated guinea-pig ileum and rat duodenum. The amount of active material excreted increases as the infection increases. The active substances are stable to boiling with hydrochloric acid but

BACKGROUND Nowadays, the Aedes aegypti mosquito represents a serious public health issue in view of the large outbreaks of the arboviral diseases zika, dengue, chikungunya and yellow fever. This holometabolous insect has midgut digestive enzymes that are trypsin- and chymotrypsin-like proteins.
