BACKGROUND Roux-en-Y gastric bypass (RYGBP) is the most common procedure for weight loss surgery but has multiple complications. This study evaluates the use of reinforced circular staplers (RCS) and their effects on reducing gastrojejunal anastomotic complications. METHODS We conducted a retrospective chart review from January 2007 to November 2008. Laparoscopic RYGBP were performed in 287 p...

Interstitial retinol-binding protein (IRBP) is a soluble glycoprotein in the interphotoreceptor matrix of bovine, human, monkey, and rat eyes. It may transport retinol between the retinal pigment epithelium and the neural retina. In light-reared Royal College of Surgeons (RCS) and RCS retinal dystrophy gene (rdy)+ rats, the amount of IRBP in the interphotoreceptor matrix increased in correspond...

In this paper, a new hybrid automatic repeat request (ARQ) scheme is proposed for data transmission in a powercontrolled direct sequence (DS) code division multiple access (CDMA) system cellular system. Data frame is composed of interleaved Reed-Solomon codes. The depth of interleaving is determined by a power-control interval. After decoding each codeword with algebraic decoding, the post-deco...

The objective was to evaluate lymphoid organ size in chickens from a series of 13 recombinant congenic strains (RCS) and their highly inbred parental lines (6(3) and 7(2)). The parental line 6(3) was selected for resistance to tumors induced by Marek's disease virus and avian leukosis viruses, whereas line 7(2) was selected for susceptibility to these tumors. Each RCS on the average contains a ...

A full-size aircraft engine-duct mock-up experimental apparatus has been built to collect cavity radar cross section (RCS) data on aircraft engine inlets. The engine-duct structure is made up of a cylindrical duct with a single fan stage consisting of 30 generic straight fan blades. Experimental results indicate that the azimuthal RCS patterns from the engine-duct are quite complex. Numerical c...

liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

By combining a transmission line system (TLS) and reverberation chamber (RC), hybrid electromagnetic compatibility (EMC) testing facility is designed constructed. Generally, the lowest usable frequency (LUF) of an RC limited by its dimension, which limits application RCs for EMC at low frequencies. Therefore, to improve field uniformity (FU) frequencies lower than LUF, TLS integrated into RC. A...

PURPOSE The authors investigated photopic electroretinographic changes during degeneration in the Royal College of Surgeons (RCS) and transgenic P23H rhodopsin rat models, including the cellular origins of a large corneal-negative component that persists in the RCS rat. METHODS Photopic and scotopic electroretinograms (ERGs) were recorded from dystrophic RCS (RCS-p(+)/Lav) rats (4-18 weeks ol...
