We studied the effects on sinus rate and atrioventricular (AV) conduction of electrical stimulation from a 12-polar electrode catheter advanced into the right pulmonary artery of 21 anesthetized dogs. In each experiment, the distal tip of the electrode catheter was positioned at a standard fluoroscopic site, and a sequence of bipolar electrograms was recorded during sinus rhythm from the 11 adj...

Abstract In enhanced geothermal systems (EGS), the natural permeability of deep rocks is normally not high enough and needs to be increased. Permeability increase can achieved through various stimulation methods, such as hydraulic, chemical, thermal stimulation. Among these, hydraulic most commonly used technique both reservoir specific area for heat exchange. A comprehensive understanding unde...

SUMMARY We investigated the induced seismicity, source mechanisms and mechanical responses of a decametre-scale hydraulic stimulation pre-existing shear zone in crystalline rock, at Grimsel Test Site, Switzerland. The analysis reveals metre-scale complexity stimulation, which remains hidden reservoir-scale. High earthquake location accuracy allowed separation four distinct clusters, three were ...

background: based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (fsh) and luteinizing hormone (lh) put on their main effects on the granulosa and theca cells. lh is essential for androgens production. androgens are used for estradiol production by granulosa cells. profound suppression of lh concentrations in some normogonadotropic patients can cau...

Brief, noxious, electrical or mechanical stimulation of the skin of Aplysia produces enhancement of defensive reflexes triggered at the same site for at least a week after the noxious stimulation. This site-specific behavioral sensitization can be expressed as an increase in duration of the siphon-withdrawal reflex and as an increase in magnitude of the tail-withdrawal reflex. It is unlikely th...

we report a case of nicolau syndrome in a 15 months old girl following of an intramuscular injection of penicillin 6.3.3 in her left buttock. this case is unique because she developed compartment syndrome in her left calf far from her injection site. her toe’s tips gangrened in the course of her ailment. we hypothesized that the compartment syndrome might be produced by a probable intra-arteria...

background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...
