conclusions nitroglycerine may be a safe and effective adjuvant therapeutic for pain reduction in patients under propofol injection. hence, its use for reduction of propofol injection-induced pain is recommended. results the pain severity in nitroglycerine group was significantly lower compared with the placebo group (p < 0.0001). moreover, the local adverse reactions were observed only in thre...

We compared the retrieval efficiency of single- (direct follicular aspiration) and double-lumen-needle (attained with follicular flushing) procedures in normal-responder IVF-intracytoplasmic sperm injection cycles. This prospective randomized study did not demonstrate a beneficial effect of double-lumen needle retrieval compared with single-needle retrieval in normal-responder IVF-intracytoplas...

Purpose. The aim of the present work was to test the feasibility of the time-resolved MR-angiography (TWIST-MRA) of cervical arteries using double bolus injection. Material and Methods. TWIST-MRA with a temporal resolution of 8.4 seconds for each frame and a spatial resolution with a voxel size of 0.61 × 0.58 × 0.8 mm(3) was performed in 24 patients. A biphasic bolus injection protocol was used...

If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...

We present a design of an IEEE oating-point multiplier capable of performing either a double-precision multiplication or a single-precision multiplication. In single-precision the la-tency is two clock cycles and in double-precision the latency is three clock cycles, where each pipeline stage contains roughly fteen logic levels. A single-precision multiplication can be followed immediately by a...

RNA interference has been used to study insects' gene function and regulation. Glycogen synthase (GS) and glycogen phosphorylase (GP) are two key enzymes in carbohydrates' conversion in insects. Glycogen content and GP and GS gene expression in several tissues and developmental stages of the Brown planthopper Nilaparvata lugens Stål (Hemiptera: Delphacidae) were analyzed in the present study, u...

The aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. Three groups of male adult rats were used in this study. The first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. The second group received double doses of busulfan with 21 days interval and their te...

Geological carbon sequestration involves large-scale injection of carbon dioxide into underground geologic formations and is considered as a potential approach for mitigating global warming. Changes in reservoir properties resulting from the CO2 injection and migration can be characterized using waveform inversions of time-lapse seismic data. The conventional approach for analysis using wavefor...
