Previous studies have shown that hyperthermia is an effective modulator of cis-diamminedichloroplatinum(II) (CDDP) cytotoxicity. We have examined the potential of inhibitors of the arachidonic acid metabolism to increase the antitumor activity of CDDP and hyperthermia. Sulindac and diflunisal are
Aedes aegypti mosquitoes are the vector for transmission of Dengue, Zika and chikungunya viruses. These mosquitos feed exclusively on human hosts for a blood meal. Previous studies have established that Dengue virus infection of the mosquito results in increased expression of the odorant binding
Changes in the production of proaggregatory (thromboxane A2 and prostaglandin E2) and antiaggregatory (prostacyclin) prostaglandins by blood platelets, macrophages and endothelial cells during acute African swine fever caused by both a highly virulent virus and a less virulent virus were studied. No
The fatty acid compositions of Malpighian tubules from adult females of the mosquito Aedes aegypti were determined for total lipids, phospholipids, triacylglycerols and three phospholipid fractions, namely phosphatidylcholine (PC), phosphatidylethanolamine (PE) and

Washed platelets of patients with familial Mediterranean fever (FMF) were incubated with I-14C arachidonic acid (AA). Only 10% of AA were transformed into thromboxane A2, 12(S)-12-hydroxy-5Z,8Z,10E,14Z-eicosatetraenoic acid (12-HETE) and 12(S)-12-hydroxy-5Z,8Z,10E-heptadecatrienoic acid (HHT), which
In conditions of acute hypoxia in the presence of hyperthermia drugs were shown to exhibit various degrees of protective activity. Antihypoxic action coupled with thermoprotective activity is manifested by beneficial affect on the course of the pathological process. It is quercitrol that proved to
Activation of the arachidonic acid cascade is an essential step for the development of fever during brain inflammation. We investigated the brain sites where this activation takes place by use of a rat model of brain inflammation. Intracerebroventricular administration of lipopolysaccharide but not
Prostaglandins (PG) E2, F2 alpha (30 ng/kg . min-1) and arachidonic acid (150 and 300 ng/kg . min-1) were infused for 30 min into the lateral cerebral ventricle of conscious hydrated and non-hydrated goats. Like previously shown as concerns PGE1 PGE2 was found to inhibit the water diuresis and cause
The effects of centrally injected prostaglandins (PGE1 and PGF2 alpha), arachidonic acid and lysine acetylsalicylate were examined on the seizure activity and temperature changes produced by pentylentetrazole (PTZ) and also on maximal electroshock (MES) seizures. PGE1 antagonised both PTZ and MES
Cyclooxygenase inhibitors such as ibuprofen have been used for decades to control fever through reducing the levels of the pyrogenic lipid transmitter prostaglandin E2 (PGE2). Historically, phospholipases have been considered to be the primary generator of the arachidonic acid (AA) precursor pool
Metabolites of cytochrome P-450 are produced in cells when arachidonic acid cascade is activated. Fever genesis depends largely on the cyclooxygenase branch of arachidonic acid cascade, which is caused by many stimuli, such as interleukin (IL)-1, IL-6, and interferon-alpha. To assess the
Increased chromosome breakage is observed in patients with familial mediterranean fever (FMF). Their plasma contains clastogenic material inducing chromosome damage in cells from healthy persons. It is proposed that increased oxyradical generation by activated polymorphonuclear cells in blood and
Halothane, in a dose-dependent manner, induced the release of intracellular Ca2+ in hepatocytes prepared from swine. The magnitude of the release induced by halothane was greater for hepatocytes prepared from animals susceptible to malignant hyperthermia (MH) than for those from normal swine. Two
