Four fractions obtained from chloroform extracts of neem (Azadirachta indica) oil by column chromatography were investigated for acaricidal activity against Sarcoptes scabiei var. cuniculi larvae in vitro. Octadecanoic acid-tetrahydrofuran-3,4-diyl ester was isolated from an active fraction of the chloroform extract and its toxicity against S. scabiei(More)
OBJECTIVE The purpose of this study is to discuss the effect of pelvic floor muscle training on fecal incontinence. METHODS A retrospective study was performed on patients who received pelvic floor muscle training from March 2002 to April 2007. There were 55 patients with fecal incontinence (male, 32 cases; female, 23 cases; mean age, 9.4 years old from 6(More)
To get insights into the principles of gene expression changes during cardiac hypertrophy, three rat cardiac hypertrophy models were prepared, i.e., suprarenal abdominal aortic stenosis (SRS), arterial-vein fistula (AVF) and continuous jugular vein infusion of norepinephrine (NEi). The cardiac function and structure were analyzed by echocardiograph as well(More)
OBJECTIVE To study the development of pelvic floor muscle, morphology and location of rectum and anal canal as well as morphology of spinal cord and sacrum based on pelvic magnetic resonance imaging(MRI) of children with fecal incontinence after anoplasty for anorectal malformation and to provide information on management of fecal incontinence. METHODS(More)
OBJECTIVE To evaluate the effects of combined Rex-bypass shunt and pericardial devascularization on prehepatic portal hypertension secondary to cavernomatous transformation of portal vein (CTPV). METHODS Forty-two patients aged from 3 years to 49 years (divided into 3 groups), 26 cases male and 16 female, with prehepatic vascular hepertention were treated(More)
Using nonequilibrium Green's function techniques, we investigate Andreev reflection and Aharonov-Bohm oscillations through a parallel-coupled double quantum dot connected with a ferromagnetic lead and a superconductor lead. The possibility of controlling Andreev reflection and Aharonov-Bohm oscillations of the system is explored by tuning the interdot(More)
Wistar rats of 8, 10 and 12-week-old were chosen for study of the relationship between cardiac growth and its gene expression profile changes during maturation. The ultrasonic parameters of rat hearts were recorded before sacrifice, then total RNA of left ventricle were extracted and gene expression profiles were analyzed by cDNA microarray. During growth(More)
