Male fruit flies touch females during courtship. A new study finds that pheromone input received through the male's foreleg allows him to generate the courtship song appealing to female flies. This activity involves sexually dimorphic fruitless-expressing neurons in the brain.

the purpose of this study was to examine the effect of indomethacin on biochemical, functional and external symptoms of delayed onset muscle soreness (doms) following eccentric exercise. for this purpose, 20 untrained, healthy male volunteers (age 25.8+6.9 years and fat 15.9+9.3 %) were selected and randomly divided into experimental (n=10) and placebo (n=10) groups. in a double blind study, su...

Besistance to blood flow through the small vessels of the dog foreleg decreased following local elevation of serum sodium and magnesium concentrations. Small vessel resistance increased following elevation of calcium concentration. Associated with the former changes was decreased responsiveness to levarterenol and methacholine. These changes likely result from effects of the cations upon the sm...

Some of the important mosquito species are generally sympatric in terms of their geographical distributions, and are difficult to identify based solely on examination of adult females using the available morphological keys. In this study, adult mosquitoes were collected indoors in Abeokuta in south-western Nigeria between August 2005 and July 2006 using Center for Disease Control light traps. T...

We present a 24-year-old female referred with non-healing wound of a few days duration on anterior aspect of her right foreleg. Biopsy of the wound was reported to be pyoderma gangrenosum on pathologic report. Further work up of the patient for high grade fever and occasional leukopenias revealed the diagnosis of cyclic neutropenia. Treatment with granulocyte colony-stimulating factor (G-CSF) r...

Direct resistance measurements in the foreleg of the anesthetized dog show that the rise in total resistance following reduction of air temperature is due predominately to small vessel constriction and is based upon at least three different mechanisms. The large arteries and veins also constrict and evidence is presented which suggests that the venous and possibly the arterial resistance respon...

In the dog foreleg acute increase and decrease of hydrogen ion concentration is associated with active small vessel dilatation and constriction, respectively, through some direct effect upon vascular smooth muscle. These small vessel resistance changes do not affect total resistance in the intact leg because of directionally opposite active changes in artery resistance. The latter response appe...

Sir,.?Two officers of this station had gone out shooting ono afternoon with three dogs. One dog which was walking ahead was bitten on the upper part of his foreleg by a very big Russell's Viper (Daboia Russellii). The officers saw the snake biting the dog which had some difficulty in getting himself released. The other two dogs when they saw what had happened, ran and caught hold of the snake; ...

BUltTON and colleagues' suggested recently that stretching the venous wall in limbs elicits a local reflex resulting in constriction of local arteriols. They felt that this "veni-vasomotor" reflex supplemented the central buffer reflexes in controlling blood flow through extremities during change in posture. Utilizing methods permitting direct measurement of small and large vessel resistance in...
