â  background treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. in this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. me t hod s a total of 150 patients with symptomatic grades ii or iii internal hemorrhoids were randomly assigned to three grou...

conclusions bosworth screw and tension band wiring are both useful procedures in patients with acj dislocation, but each should be used in the selected patients with special indications. both methods had good results during follow-up period. there was not statistically meaningful difference in the articular stability, range of motion, oss score and vast score between the two groups (p > 0.05). ...

A simple and compact high gain Dielectric Resonator Antenna (DRA) for Ku band frequency operation is proposed in this paper. Ku band is a microwave band having frequency range 12 to 18 GHz. Proposed DRA is based on the principal of the dual resonance and defected ground structure (DGS) having rectangular slot. DRA design resonates at frequency 15.2 GHz and 18 GHz in Ku band frequency operation....

PURPOSE The aim of this study was to compare the efficacy and safety of band ligation and injection sclerotherapy in the endoscopic treatment of children with variceal bleeding. METHODS The study population included 55 children, all of whom were treated at the time of endoscopic diagnosis of esophageal varices at Asan Medical Center, Seoul, Korea, between January 1994 and January 2011. The pr...

Transparent conductors are neither 100% optically transparent nor metallically conductive. From the band structure point of view, the combination of the two properties in the same material is contradictory: a transparent material is an insulator which possesses completely filled valence and empty conduction bands; whereas metallic conductivity appears when the Fermi level lies within a band wit...

OBJECTIVES To study the incidence of band erosion in patients who have undergone vertical banded gastroplasty and to describe the reparative techniques used. DESIGN A retrospective review case series. SETTING A university hospital-based tertiary referral center. PATIENTS Two hundred fifty consecutive morbidly obese patients who underwent vertical banded gastroplasty between 1987 and 1995....

Introduction: Serpentines are 1:1 trioctahedral phyllosilicates with general formula (Fe,Mg)6Si4O10(OH)8 and form during metamorphism, hydrothermal activity, or weathering of ultramafic rocks. Serpentine is an expected aqueous alteration product on Mars, given the mafic to ultramafic crust and prevalence of olivine. Serpentinziation reactions produce H2, which can serve as an important energy s...

The functional significance of resting state networks and their abnormal manifestations in psychiatric disorders are firmly established, as is the importance of the cortical rhythms in mediating these networks. Resting state networks are known to undergo substantial reorganization from childhood to adulthood, but whether distinct cortical rhythms, which are generated by separable neural mechani...

Nonthermal X-rays and very high-energy (VHE) γ-rays have been detected from the supernova remnant (SNR) RX J1713.7-3946, and especially the recent observations with the Suzaku satellite clearly reveal a spectral cutoff in the X-ray spectrum, which directly relates to the cutoff of the energy spectrum of the parent electrons. However, whether the origin of the VHE γ-rays from the SNR is hadronic...

doscopic variceal ligation. The Stieg− mann±Goff ligator works by pulling a string to deploy the band [1], but requires an overtube for multiple ligations. Saeed’s multishooter has the advantage of single insertion, pulling a single band at a time and is able to shoot six bands [2]. Most multishooters use a double thread, however, which hampers the en− doscopic view. Our single−thread system ha...
