CCl4-induced toxic damage to the liver in rats and rabbits is accompanied by inhibition of detoxifying functions of the liver and a decrease in plasma alpha1-antitrypsin content and core body temperature. Injection of pyrogenal stimulated detoxifying functions of the liver, elevated
The P-gp/MDR1 multidrug transporter mediates detoxification of numerous drugs, including colchicine, and CYP3A4 is key to the biotransformation of colchicine. We investigated the effects of CYP3A4 and P-gp/MDR1 polymorphisms on bioavailability of colchicine in patients with Familial Mediterranean
The incidence of mosquito-borne disease poses a significant threat to human and animal health throughout the world, with effective chemical control interventions limited by widespread insecticide resistance. Recent evidence suggests that gut bacteria of mosquitoes, known to be essential in
In conscious unrestrained rats, at an ambient temperature of 22 degrees C, oesophageal temperature was measured and temperature effect of single and repeated intravenous injection of E. coli endotoxin was examined. The first injection of endotoxin in a dose of 10.0 mug/rat did not change the rat
Multidrug resistance is a major obstacle for the successful use of chemotherapy. The multidrug resistance phenotype is often attributed to overexpression of P-glycoprotein, which is an energy-dependent drug efflux pump. We investigated a new strategy to overcome multidrug resistance, using purified
Our previous findings [Hazelton & Lang (1978) Fed. Proc. Fed. Am. Soc. Exp. Biol. 37(6), 2378 (abstr.)] demonstrated aging-specific changes in glutathione concentrations in the yellow-fever mosquito [Aedes aegypti (Louisville)]. A possible mechanism could be increased utilization via glutathione
Aedes aegypti (L.) is the vector responsible for transmitting dengue, chikungunya, yellow fever, and Zika viruses, as well as other pathogens. Microbial larvicides based on Bacillus thuringiensis Berliner israelensis (Bti) and Saccharopolyspora spinosa Mertz and Yao, such as VectoBac 12AS and
Mosquitoes serve as vector for transmitting diseases. Among mosquitoes, Culex quinquefasciatus transmits lymphatic filariasis, yellow fever Japanese encephalitis etc. Application of chemical insecticides is still the best option for vector control programmes. Continuous use of these chemicals on
BACKGROUND
Haemaphysalis longicornis is a tick of importance to health, as it serves as a vector of several pathogens, including Theileria orientalis, Babesia ovata, Rickettsia japonica and the severe fever with thrombocytopenia syndrome virus (SFTSV). Presently, the major method of control for this
Hyperthermia results in protein unfolding that, if not properly chaperoned by Heat Shock Proteins (HSP), can lead to irreversible and toxic protein aggregates. Elevating HSP prior to heating makes cells thermotolerant. Hyperthermia also can enhance the sensitivity of cells to radiation and drugs.
The levels of resistance to two organophosphate acaricides, coumaphos and diazinon, in several Mexican strains of Boophilus microplus (Canestrini) were evaluated using the FAO larval packet test. Regression analysis of LC50 data revealed a significant cross-resistance pattern between those two
The mosquito Aedes aegypti is the main vector of Dengue and Yellow Fever flaviviruses. The organophosphate insecticide temephos is a larvicide that is used globally to control Ae. aegypti populations; many of which have in turn evolved resistance. Target site alteration in the acetylcholine esterase
The larvae and adults of Aedes aegypti were tested for the potential to develop resistance to the synthetic pyrethroid, deltamethrin, alone or a combination of deltamethrin with the synergist, piperonyl butoxide (PBO). Although continuous larval selection for 40 generations resulted in 703-fold
The development of tumor cell drug resistance is a major obstacle which often leads to failure of cancer chemotherapy. Therefore, reversing the cell drug resistance would have important implications in cancer treatment. We have developed a cisplatin-resistant mouse tumor cell line from the radiation
