Objectives To compare endoscopic and open carpal tunnel release surgery among employed patients with carpal tunnel syndrome. Design and setting Randomised controlled trial at a single orthopaedic department. Participants 128 employed patients aged 25-60 years with clinically diagnosed and electrophysiologically confirmed idiopathic carpal tunnel syndrome. Main outcome measures The primary outcome

This report presents the addition of camber to a previously published semi-empirical tire model by the same authors. The model combines empirical models for pure braking, cornering and cambering to a model for simultaneous braking, cornering and cambering. It is based on brush-model tire mechanics and aims to offer an easy-to-use accurate model for vehicle handling-simulations. The proposed model

The effect of kinship on growth and use of space by individually PIT-tagged 1+ brown trout was studied for 11 weeks in eight stream enclosures. Each enclosure consisted of two sections, separated by a region containing PIT-detecting antennae, which enabled us to measure use of sections by all individuals. Two types of sibling groups were tested, a single sibling group, F1, consisting of four indiv

The proton structure function F-2(x, Q(2)) is measured in inelastic QED Compton scattering using data collected with the H1 detector at HERA. QED Compton events are used to access the kinematic range of very low virtualities of the exchanged photon, Q(2), down to 0.5 GeV2, and Bjorken x up to similar to 0.06, a region which has not been covered previously by inclusive measurements at HERA. The res

Using recently developed algorithms based on Cholesky decomposition of two-electron integrals to compute response properties at the correlated level, the static and dynamic (at 589 nm) polarizabilities of [4n + 2]-annulenes (n = 1, 2, 3, 4) have been calculated. The results show that the perpendicular component increases along the series linearly with the number of double bonds. The in-plane stati

During the last few years several genetic markers have been discovered that contribute to an increased risk of venous thrombosis. Patients who have several genetic markers are at a considerably higher risk of being affected than patients with only one marker. Recommendations are made as to which patients should be investigated, with appropriate laboratory analyses, when an increased risk of venous

This study deals with technological capability building of local auto parts firms in Malaysia and Thailand during the period 1960-2000. Malaysia introduced a national car programme in 1985 while Thailand has maintained its liberal economic policy and relies on foreign multinational automakers to operate in the country. The study focuses on an empirical survey of 41 and 42 local auto parts firms in

Concentrations of PCB congeners were determined in precipitation and the annual and seasonal depositional fluxes were calculated for 16 (mostly rural) stations around the Baltic Sea during 1990-1993. The concentrations of individual congeners in precipitation were found to be influenced by atmospheric concentrations of PCBs, ambient temperature, precipitation volume and physico-chemical properties

We announce the detection of two fully resolved hyperfine components of the intercombination line of Tl II (Z = 81) at 1908.6 Angstrom in the ultraviolet spectrum of the sharp-lined, nonmagnetic, chemically peculiar star chi Lupi (BB.5pHgMn + A2 Vm). The wavelengths and profiles of these absorption lines strongly suggest that they arise from the heaviest isotope, Tl-205. The echelle observations w

Breeding success in birds may be determined by the availability of food that parents can provide to growing nestlings. A standard method for testing the occurrence of food limitation is to provide supplemental food during different parts of the breeding period. If there is spatial variation in the strength of food limitation, the effect of such an experiment should also vary spatially. We investig

The perforated patch whole-cell configuration of the patch-clamp technique was applied to superficial glucagon-secreting alpha-cells in intact mouse pancreatic islets. alpha-cells were distinguished from the beta- and delta-cells by the presence of a large TTX-blockable Na+ current, a TEA-resistant transient K+ current sensitive to 4-AP (A-current) and the presence of two kinetically separable Ca2

The production of tau leptons in ep collisions is investigated using data recorded by the H1 detector at HERA in the period 1994-2000. Tau leptons are identified by detecting their decay products, using leptonic and hadronic decay modes. The cross section for the production of tau lepton pairs is measured for the first time at HERA. Furthermore, a search for events with an energetic isolated tau l

OBJECTIVES: Long-term, low-dose macrolide therapy is effective in the treatment of chronic rhinosinusitis. The mechanism of its anti-inflammatory effect and how this differs from corticosteroids remains unclear. The effect of clarithromycin and prednisolone on interleukin-5, interleukin-8, and granulocyte-macrophage colony-stimulating factor production by cultured chronic sinusitis nasal mucosa wa

In order to give adequate support to risk managers, new risk assessment methods should be developed that are (1) scientifically sound, (2) simplified, and (3) suited for precautionary risk management. In this Perspective we propose that the notion of a precautionary default can be a useful tool in the development of such methods. A precautionary default is a cautious or pessimistic assumption that
