We have identified, using composite interval mapping, quantitative trait loci (QTL) affecting a variety of life history traits (LHTs) in the nematode Caenorhabditis elegans. Using recombinant inbred strains assayed on the surface of agar plates, we found QTL for survival, early fertility, age of onset of sexual maturity, and population growth rate. There was no overall correlation between survi...

susceptibility of two wild strains of an. stepliens, collected from kazeroun (st-k.az and bandar-abbas (st-ban), south of iran was compared to fenthion, malathion, temephos , pirimiphos, methyk, deltamethrth, ddt dimilin and etopenprox as larvicides in the laboratory. susceptibility test on the st-kaz strain indicated that this strain is susceptible to the named insecticides i.e. the resistance...

We hypothesize that when a broad spectrum of bone strain is considered, strain history is similar for different bones in different species. Using a data collection protocol with a fine resolution, mid-diaphyseal strains were measured in vivo for both weightbearing and non-weightbearing bones in three species: dog, sheep, and turkey, with strain information collected continuously while the anima...

OBJECTIVE To assess whether a history of lumbar stress fracture in pace bowlers in cricket is a risk factor for lower limb muscle strains. METHODS This was a prospective cohort risk factor study, conducted using injury data from contracted first class pace bowlers in Australia during seasons 1998-1999 to 2008-2009 inclusive. There were 205 pace bowlers, 33 of whom suffered a lumbar stress fra...
