background: sodium valproate (sv) has been approved for migraine prophylaxis and its intravenous form is used to treat acute migraine attacks. we compared the efficacy and safety of intravenous sv and subcutaneous sumatriptan in managing acute migraine attacks. methods: this double-blind randomized clinical trial divided 90 patients into two groups: one group received 400 mg of intravenous sv a...

VIBR~,TION~.L directions of direct shear waves from a number of small local earthquakes in southern California, recorded at Pasadena and Riverside, are determined and related to corresponding faulting at the source. A theoretical relationship between wave vibrational directions and fault displacements is proposed. Directions of SV and SIt motions from various fault types are adduced from this r...

Background: Sodium valproate (SV) has been approved for migraine prophylaxis and its intravenous form is used to treat acute migraine attacks. We compared the efficacy and safety of intravenous SV and subcutaneous Sumatriptan in managing acute migraine attacks.

In view of the insufficient analysis coupled joint seismic response intake tower–reservoir water–foundation boundary under oblique incidence SV wave space, a three-dimensional dynamic equation space is established in this paper. The external input method viscoelastic artificial combined with equivalent load and acoustic medium theory are used to simulate action reservoir water, angle change rea...

F our-component ocean-bottom-cable (4-COBC) seismic data acquired in deep water across the Gulf of Mexico were used to study near-sea-floor geologic characteristics of fluid-gas expulsion systems. Although these 4-C OBC data were acquired to evaluate oil and gas prospects far below the sea floor, the data have great value for studying near-sea-floor geology. The research results summarized here...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

Waveform patterns of P, ST and T vector functions of Frank-lead rest and exercise vectorcardiograms (VCG) of 375 ostensibly normal males, aged 50-70 years, were evaluated by waveform vector analysis (WVA). This procedure suitably quantified waveform information, providing a stable reduced data base comprising mean vector (MV), gradient vector (GV), convex vector (CV), sigmoid vector (SV), and q...

BACKGROUND Few studies have examined parental perceptions of their child's screen-viewing (SV) within the context of parental SV time. This study qualitatively examined parents' perceptions of their 5-6-year-old child's SV within the context of their own quantitatively measured SV. METHODS A mixed-methods design employed semi-structured telephone interviews, demographic and SV questionnaires,...

PURPOSE To study by ultrasounds cardiac morphology and function early after breath-hold diving in deep water in elite athletes. METHODS Fifteen healthy male divers (age 28 +/- 3 years) were studied using Doppler-echocardiography, immediately before (basal condition, BC) and two minutes after breath-hold diving (40 meters, acute post-apnea condition, APAC). Each subject performed a series of t...
