in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

OBJECTIVE To compare sonographic endometrial characteristics in in-vitro fertilization (IVF) cycles between women who conceive and those who do not. METHODS Thirty-five women undergoing IVF treatment participated in the study. Using three-dimensional (3D) power Doppler ultrasound, we assessed endometrial patterns, volume and vascularization, after follicle stimulating hormone (FSH) stimulatio...

The present study aims at investigating effectiveness of the quadruple (early-pilot-main-after [epMa]) injection strategy over three different triple [early-main-after (eMa), early-pilot-main (epM) and pilot-main-after (pMa)] scheduling in terms emissions, performance [brake specific fuel consumption (BSFC), torque, brake thermal efficiency (BTE) economy] noise. experimentation was carried out ...

A major challenge in breast cancer therapy is the lack of an effective therapeutic option for a particularly aggressive subtype of breast cancer, triple-negative breast cancer. Here we provide the first preclinical evidence that a second-generation selenium compound, methylseleninic acid, significantly enhances the anticancer efficacy of paclitaxel in triple-negative breast cancer. Through comb...

Augmentation of specific chemoimmunotherapy by daily, intrasplenic injection of interleukin-2 (IL-2) was assessed in a methylcholanthrene (MCA)-induced fibrosarcoma model in C3H/HeJ mice. Daily access to the spleen was achieved by relocating the organ into the subcutis while leaving its blood supply intact. Following intrasplenic injection of 80 units of human IL-2 into MCA-F tumor-bearing mice...

aim and background:   pain management is very important in tonsillectomy in order to reduce the suffering and restlessness in children. the aim of this study was to investigate the effect of peritonsillar injection of lidocaine and placebo preoperatively on postoperative pain relief. methods and materials:   this randomized triple blind clinical trial conducted on sixty 3-12- year-old children ...

BACKGROUND AND PURPOSES New strategies have been developed to improve the sensitivity of contrast-enhanced MR imaging in quantifying disease activity in patients with multiple sclerosis (MS). The goal of the present study was to evaluate the sensitivity of T1-weighted images after injection of a triple dose of contrast material and application of a magnetization transfer (MT) pulse in the detec...

OBJECTIVES To evaluate whether a triple dose of gadolinium-DTPA (Gd-DTPA) or delayed MRI increase the number, size, and conspicuousness of enhancing lesions in patients with benign multiple sclerosis. METHODS T1 weighted brain MRI was carried out on 20 patients with benign multiple sclerosis (expanded disability status scale < 3 with a disease duration > 10 years) in two sessions. In the firs...
