ribonucleic acid/fever

Protein and ribonucleic acid (RNA) syntheses increase in the liver during Q fever, coincident with progressive increments in cortisol levels. Cell-free protein-synthesizing systems indicate that the pH 5 enzyme fraction was chiefly responsible for enhanced activity. Although the polysome profiles

Liver glycogen is depleted in guinea pigs infected with Coxiella burneti. Syntheses of the glycogen precursors uridine triphosphate and uridine diphosphate glucose are unaffected during Q fever, but glycogen synthetase activity is inhibited. Exogenous cortisol relieves this inhibition in infected

Experimental studies undertaken to ascertain the dynamics of yellow fever virus replication in an introduced strain (Houston) of the Asian mosquito, Aedes albopictus (Skuse), indicate that this species is an efficient vector of yellow fever virus. Replication of virus in Ae. albopictus could be

OBJECTIVE To provide a comprehensive review of dengue, with an emphasis on clinical syndromes, classification, diagnosis, and management, and to outline relevant aspects of epidemiology, immunopathogenesis, and prevention strategies. Dengue, a leading cause of childhood mortality in Asia and South

A rapid, simple diagnostic polymerase chain reaction (PCR) method for the diagnosis of dengue fever was developed using a pair of consensus oligonucleotide primers and validated with laboratory-derived strains of dengue serotypes 1-4 and other common flaviviruses. A cluster of 13 patients with

Experiments were performed to characterize the pyrogenic principle of ribonucleic acid (RNA) from the yeast Candida utilis. It was shown that ribonuclease hydrolysis of the RNA does not lead to inactivation of the pyrogenicity. Pyrogenicity was, however, destroyed by treatment with sodium

Leucocyte migration inhibition (LMI) tests have been performed with leucocytes obtained from patients with acute rheumatic carditis, established rheumatic valvular disease with and without rheumatic reactivation, post-streptococcal glomerulonephritis and healthy volunteers, using human heart valve

Analyses of the viral ribonucleic acids and structural polypeptides of 17-22 of the 119 accepted or proposed members of the Bunyavirus genus of arboviruses (family Bunyaviridae), have shown that from the standpoint of their structural components these viruses are highly comparable to each other. The

Ticks are reservoir hosts of pathogenic Rickettsia in humans and domestic animals. Most pathogenic Rickettsia species belong to the spotted fever group (SFG). The present study aimed to determine the tick species infected with Rickettsia based on the genus-specific 23S ribosomal ribonucleic acid
