The mosquito Aedes aegypti is the principal vector of dengue and yellow fever flaviviruses. Permethrin is an insecticide used to suppress Ae. aegypti adult populations but metabolic and target site resistance to pyrethroids has evolved in many locations worldwide. Quantitative trait loci (QTL) controlling permethrin survival in Ae. aegypti were mapped in an F(3) advanced intercross line. Parent...

Although many studies concerning the sensitivity mechanism of scorpion toxin-potassium channel interactions have been reported, few have explored the biochemical insensitivity mechanisms of potassium channel receptors toward natural scorpion toxin peptides, such as the KCNQ1 channel. Here, by sequence alignment analyses of the human KCNQ1 channel and scorpion potassium channel MmKv2, which is c...

Abstract The mitotic-inhibiting herbicide pronamide controls susceptible annual bluegrass ( Poa annua L.) pre- and postemergence, but in some resistant populations, postemergence activity is compromised, hypothetically due to a target-site mutation, lack of root uptake, or an unknown resistance mechanism. Three suspected pronamide-resistant (LH-R, SC-R, SL-R) two pronamide-susceptible (BS-S HH-...

The complete form of androgen insensitivity syndrome (testicular feminization) occurs in a 46,XY karyotype with a mutant X-linked recessive gene that is responsible for the androgen intracellular receptor [l]. An individual with androgen insensitivity syndrome is a male pseudohermaphrodite. Phenotypic characterizations include scanty or absent axillary and pubic hair, slight vulvar hair, a rudi...
