Four strains (SS, BS, A and B) of Aedes aegypti collected from different sites in Bangkok and at different times were examined for their pyrethroid susceptibility. Mosquito coils containing dl, d-T80-allethrin, d, d-T-prallethrin and methoxymethyl-tetrafluorobenzyl tetramethyl-cyclopropanecarboxylate (K-3050) with or without a synergist were tested by the 25 m3 semi-field test method. One strai...

background : insecticide resistance is one of the serious problems for german cockroach control program. this study was conducted to determine the bendiocarb and carbaryl resistance mechanisms in german cockroaches using the piperonyl butoxide (pbo). methods : bioassay tests were conducted with 4 to 6 different concentrations of both insecticides with four replicates of 10 susceptible strain co...

[Purpose] This study aims to analyze the effect that moderate to severe chronic obstructive pulmonary disease (COPD) has on the respiratory synergist muscles. The results will provide basic data that can be used in the clinical management of COPD. [Subjects and Methods] The subjects in the study were 47 male patients with COPD between 55 and 70 years old who were treated in a medical institutio...

[Purpose] It is well-known that the muscles of spinal stability also play roles in respiration. The spinal stability muscles are divided into two subgroups, the local muscle group and the global muscle group. Appropriately coordinated activation of muscle groups are recommended for more efficient spinal stability. The indirect method of measuring coordination of muscle groups is the synergist r...

After nerve-repair grafting of medial gastrocnemius muscle, there is incomplete recovery of specific force and sustainable power, perhaps due to overcompensation by synergistic muscles. We hypothesized that increased workload due to synergist ablation would enhance graft recovery. Contractile and metabolic properties of control and nerve-repair grafted muscles, with and without synergist ablati...

We investigated the mechanisms conferring resistance to methyl-parathion (44-fold) and to methomyl (8-fold) in Tetranychus urticae from Greece by studying the effect of synergists on the resistance and the kinetic characteristics of various enzymes in a resistant strain (RLAB) and a susceptible reference strain (SAMB). It is shown that S,S,S-tributyl phosphorotrithioate, a synergist that inhibi...

During an investigation of the serotonin content of normal and schizophrenic blood sera, it was observed that many sera from severely schizophrenic patients contained a substance which augmented the response (contraction) of the isolated rat uterus to serotonin. Doses of serotonin which were too small to cause a contraction of the uterus by themselves did so when dilutions of these sera were ad...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

The purpose of the study was to examine the effect of prolonged tonic vibration applied to a single synergist muscle on maximal voluntary contraction (MVC) and maximal rate of force development (dF/dt(max)). The knee extension MVC force and surface electromyogram (EMG) from the rectus femoris (RF), vastus lateralis (VL), and vastus medialis (VM) during MVC were recorded before and after vibrati...
