OBJECTIVE To explore the effects of gene transfer of insulin like growth factor-1 (IGF-1) on the penis of senile rats and the altered levels of mRNA and protein of endothelial nitric oxide synthase (eNOS). METHODS Ten young (4 months) and 20 senile (24 months) Sprague-Dawley male rats were selected. The senile rats were divided into 2 groups: phosphate(More)
OBJECTIVE To study the expression of the mRNAs of transient receptor potential (TRP) gene subfamily TRPV and TRPM in rat testes. METHODS Normal SD rat testes were collected and the expression of TRPV and TRPM mRNAs were detected by routine RT-PCR. RESULTS The TRPV4, TRPV5, TRPV6, TRPM3, TRPM4 and TRPM8 mRNAs were detected in the rat testes, but the(More)
OBJECTIVE To compare the surgical effect of three-dimensional (3D) versus 2D laparoscopic surgery in ureter lithotomy. METHODS From January 2014 to 2015 May, 45 patients with ureteral calculi were randomly allocated into 2 groups to undergo ureter lithotomy under 3D laparoscopy (25 cases) and 2D laparoscopy (20 cases). The time used for each surgical(More)
INTRODUCTION Previous studies have confirmed the gene transfer of insulin-like growth factor-1 (IGF-1) and the IGF-1 protein can improve the erectile function in aging rats. IGF binding protein (BP)-3 can regulates the availability of IGF-I. The higher expression of IGFBP-3 may play an important role in erectile dysfunction (ED). AIM The study aimed to(More)
OBJECTIVE To compare the safety, feasibility and efficacy of transperitoneal and retroperitoneal laparoscopic partial nephrectomy (LPN) in the treatment of renal tumors with R. E. N. A. L score more than 7. METHODS The clinical data were collected from 62 patients undergoing transperitoneal LPN (32 cases) and retroperitoneal LPN (30 cases) for a complex(More)
Metal-organic frameworks (MOFs) are entities with a repertoire of dynamic functions. With a simple touch of salts, smooth crystals of MOFs can be turned into hairy ones, dramatically enhancing chemisorption of large molecules, i.e., by 120 times. When this process is followed by another round of etching, sequential binding of different proteins is possible.
We present simple, self-assembled, and robust fabrication of ultrahigh density cobalt nanowire arrays. The binary Co-Al and Co-Si systems phase-separate during physical vapor deposition, resulting in Co nanowire arrays with average diameter as small as 4.9 nm and nanowire density on the order of 10(16)/m(2). The nanowire diameters were controlled by(More)
OBJECTIVE The aim of this study was determine whether intracavernosal injection (ICI) of insulin-like growth factor-1 (IGF-1) protein can improve corpus cavernosal smooth muscle relaxation in aging rats. MATERIALS AND METHODS Ten young (4-month-old) and 30 old (24-month-old) Sprague-Dawley male rats were enrolled in the study. The old rats were divided(More)
