The compression efficiency of a rolling piston type rotary compressor for room airconditioners was analyzed, Suction passage loss is one of the detracting factors in compression efficiency and we studied its main cause, i.e. the pressure pulsation generated in the suction line, and clarified the relation between suction line specification and suction passage loss. A method of evaluating the suc...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...

BACKGROUND We aimed to evaluate an approach to induced abortions during early pregnancies that controls the suction pressure and restricts the duration of the procedure. METHODS Three hundred patients programmed for induced early pregnancy abortions, hospitalized in the Shandong Provincial Maternity & Child-care Hospital from October 2013 to October 2015, were enrolled. Patients were randomly...

BACKGROUND Recent evidence suggests that endoscopically obtained cultures from the middle meatus give comparable results to antral puncture for acute sinusitis. The best method for obtaining middle meatal cultures remains somewhat controversial because it has been theorized that specimens obtained with a swab are contaminated easily. This study compares endoscopic culture results from two diffe...

ObjectiveTo describe the etiology of arteriovenous malformations (AVM) and enhanced myometrial vascularity (EMV), review updates in management for patients with retained products conception (RPOC) associated EMV through a case presentation.DesignA 6-minute narrated video discusses recent distinction between AVM. The etiology, symptoms, imaging findings/interpretation, based on symptoms are revi...

BACKGROUND The incidence of molar pregnancy has demonstrated marked geographic and ethnic differences. The reported data in Nepal is inconsistent with minimal published literature. Thus, we designed a study to determine prevalence of molar pregnancies and demonstrate clinical and epidemiological characteristics of the patients attending a tertiary care center in eastern Nepal. METHODS A retro...

BACKGROUND Misoprostol is widely used in obstetrics and gynaecology for medical abortion, cervical priming and induction of labour. To aid the design of effective and safe regimens, we have investigated the pharmacokinetic parameters after the vaginal or sublingual administration of repeated doses of 400 microg of misoprostol. METHODS Women undergoing termination of pregnancy by suction evacu...

Purpose:Overexpression of the oncogen Stathmin has been linked to aggressive endometrial carcinoma and a potential for PI3Kinase inhibitors in this disease. We wanted to validate the prognostic value of Stathmin expression in a large prospective multicenter setting. As lymph node sampling is part of current surgical staging, we also aimed to test if Stathmin expression in endometrial curettage ...

UNLABELLED Objective : There is an increasing rate of ectopic pregnancy with the use of assisted reproductive techniques. There is currently no serum test to differentiate ectopic pregnancy from miscarriage. Early and accurate detection of ectopic pregnancy may prevent the development of complications. The aim of this study was whether the ratio of serum/curettage material hCG could provide us ...

OBJECTIVES To examined the diagnostic value of  dilatation and curettage (D and C) in patients with abnormal uterine bleeding (AUB) by conducting a histopathological examination of endometrial tissues by D and C and hysterectomy. Methods: In this retrospective study, the medical records of 163 women who had been hospitalized  in the Obstetrics and Gynecology Ward, Amir-al-Momenin Hospital, Semn...
