High-resolution structure of a Kazal-type serine protease inhibitor from the dengue vector Aedes aegypti
(Int Union Crystallography, 2017)
Blood-feeding exoparasites are rich sources of protease inhibitors, and the mosquito Aedes aegypti, which is a vector of Dengue virus, Yellow fever virus, Chikungunya virus and Zika virus, is no exception. AaTI is a ...
Influence of age on the febrile response to E. coli and S. typhimurium endotoxins in growing pullets.
(1992-09-01)
1. The effect of bacterial endotoxin injection was studied in growing pullets of different ages. Commercial chicks were divided into 5 groups according to age. Bacterial endotoxins (E. coli and S. typhimurium) were injected ...
Reação metabólica à infecção no hospedeiro.
(1992-05-01)
At the site of local reaction to infection the interleukin-1 (1L-1) is released signaling to distant tissues the presence of infection and attempting to strengthen the host's defenses and inhibit the bacterial growth. This ...
EFFECTS OF ENDOTOXIN, INTERLEUKIN-1-BETA AND PROSTAGLANDIN INJECTIONS ON FEVER RESPONSE IN BROILERS
(Carfax Publ Co, 1993-12-01)
1. The effect of endotoxin, interleukin-1 beta and prostaglandin on fever response was studied in 80 broilers (Hubbard strain). Endotoxin (E. coli, LPS) was injected iv (1.5 mu g/kg) and icv (1.5 mu g/bird); interleukin-1 ...
Hepatocyte lesions and cellular immune response in yellow fever infection
(Elsevier B.V., 2007-02-01)
The study of the in-situ cellular immune response is very important for the understanding of different liver infections. In the present study, 53 liver samples obtained by viscerotomy from patients who died during the ...
RNA interference inhibits yellow fever virus replication in vitro and in vivo
(Springer, 2009-04-01)
RNA interference (RNAi) is a process that is induced by double stranded RNA and involves the degradation of specific sequences of mRNA in the cytoplasm of the eukaryotic cells. It has been used as an antiviral tool against ...

Fever response induced by intravenous and intracerebrovascular injection of pyrogen in thyroidectomised and protein-calorie malnourished rabbits
(1990-02-14)
The development of a fever in response to intravenous (IV, 1.5 μg/kg body mass) and intracerebroventricular (ICV, 1.5 μg/animal) injections of Escherichia coli lipopolysaccharide (LPS) was studied in control, thyroidectomised ...
Observations on the development of the febrile response to pyrogen in newborn pigs
(1985-12-01)
The febrile response of newborn pigs to exogenous pyrogen injection was investigated. Lipopolysacharides (LPS, E coli) were injected intravenously into the superior vena cava of 1-30-day-old piglets. All the experiments ...
