The RTS=CTS reservation scheme in IEEE 802.11a Wireless LANs (WLANs) is employed to improve performance as it shortens packet collision duration and addresses the hidden station problem. An investigation has been conducted into how effective the RTS=CTS handshake is in reducing collision duration for 54 Mbit=s by extending an existing mathematical model for the particular packet overheads and d...

The nature of intestinal absorption of most herbal medicine is unknown. Cryptotanshinone (CTS) is the principal active constituent of the widely used cardiovascular herb Salvia miltiorrhiza (Danshen). We investigated the oral bioavailability of CTS in rats and the mechanism for its intestinal absorption using several in vitro and in vivo models: 1) Caco-2 cell monolayers; 2) monolayers of MDCKI...

The delicate tuning of digit forces to object properties can be disrupted by a number of neurological and musculoskeletal diseases. One such condition is Carpal Tunnel Syndrome (CTS), a compression neuropathy of the median nerve that causes sensory and motor deficits in a subset of digits in the hand. Whereas the effects of CTS on median nerve physiology are well understood, the extent to which...

OBJECTIVES Traditionally, nerve conduction study (NCS) are used to diagnose carpal tunnel syndrome (CTS). However, no NCS has the sufficient sensitivity or specificity values to diagnose CTS by itself. Median terminal latency index (mTLI) and median residual latency (mRL) are parameters that calculated to identify abnormalities in distal segments of the median motor nerve. There are few studies...

OBJECTIVE To evaluate each digital branch of the median sensory nerve and motor nerves to abductor pollicis brevis (APB) and 2nd lumbrical (2L) according to the severity of carpal tunnel syndrome (CTS). METHODS A prospective study was performed in 67 hands of 41 patients with CTS consisting of mild, 23; moderate, 27; and severe cases, 17. Compound muscle action potentials (CMAPs) were obtaine...

BACKGROUND Carpal tunnel syndrome (CTS) is known as a repetitive motion disorder, but the role of other diseases in the development or prognosis of CTS is uncertain. We reviewed the literature to determine whether there is evidence for an increased prevalence of specific conditions in CTS patients and whether this evidence would support laboratory screening for these conditions. METHODS Medli...

RATIONALE AND OBJECTIVES Discrepancy rates for interpretations produced in a call situation are one metric to evaluate residents during training. Current benchmarks, reported in previous studies, do not consider the effects of practice pattern variability among attending radiologists. This study aims to investigate the impact of attending variability on resident discrepancy rates to determine i...

The effects of condensed tannins (CTs) extracted from pine bark on egg hatching, larval development and the viability of infective L3 larvae of Trichostrongylus colubriformis (Giles, 1892) and Teladorsagia circumcincta (Stadelmann, 1894) (syn. Ostertagia circumcincta) were evaluated using in vitro bioassays. Significant inhibitory effects of CTs were obtained on the viability of the infective l...

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy of the median nerve characterized by paresthesias and pain in the first through fourth digits. We hypothesize that aberrant afferent input from CTS will lead to maladaptive cortical plasticity, which may be corrected by appropriate therapy. Functional MRI (fMRI) scanning and clinical testing was performed on CTS patients at baseline...

BACKGROUND A critical aspect of clinical and translational science (CTS) is interdisciplinary and collaborative research, which increasingly requires a wide range of computational and human resources. However, few studies have systematically analyzed such resource needs of CTS researchers. OBJECTIVE To improve our understanding of CTS researchers' needs for computational and human resources i...
