A prospective study was conducted to evaluate the efficacy and safety of two-portal endoscopic carpal tunnel release. Two hundred and fifty-five consecutive hands (204 patients) were operated on by one surgeon using general or regional anaesthesia in the first 48 hands and local anaesthesia in the following 207 hands. The patients were evaluated preoperatively and 3 and 6 months postoperatively by
The growth of suitable protein crystals is an essential step in the structure determination of a protein by X-ray crystallography. At present, crystals are mostly grown using trial-and-error procedures, and protocols that rapidly screen for the crystal nucleation step are rare. Presented here is an approach to minimize the consumption of precious protein material while searching for the nucleation
The interaction between localized and extended vibrational modes in solids is of central importance in understanding how local vibrational modes decay into phonons. Interstitial oxygen (O-i) in silicon is a model system for studying such interactions. Using hydrostatic pressure, we have brought the antisymmetric stretch mode of O-18(i) in silicon into resonance with the second harmonic of the O-18
Introduction In a cross between two mouse strains, the susceptible B10.RIII (H-2r) and resistant RIIIS/J (H-2r) strains, a locus on mouse chromosome 5 (Eae39) was previously shown to control experimental autoimmune encephalomyelitis (EAE). Recently, quantitative trait loci (QTL), linked to disease in different experimental arthritis models, were mapped to this region. The aim of the present study
OBJECTIVE: To compare the differences in standing balance and gait performance between two populations, correlated with age and physical activities of daily living. DESIGN: A cross-sectional study. SETTINGS: Malmo, the third largest city in Sweden, and Sjobo, a typical agricultural community 60 km east of Malmo. PARTICIPANTS: Participants were 570 men and women from the urban community (urban) and
Objective: To compare long-term patient outcome in a prospective randomized controlled trial between unilateral and bilateral neck exploration for primary hyperparathyroidism (pHPT). Summary Background Data: Minimal invasive and/or focused parathyroidectomy has challenged the traditional bilateral neck exploration for pHPT. Between 1997 and 2001, we conducted the first unselected randomized contro
PURPOSE: EUROCARE collected data from population-based cancer registries in 20 European countries. We used this data to compare childhood cancer survival time trends in Europe. PATIENTS AND METHODS: Survival in 44,129 children diagnosed under the age of 15 years during 1983 to 1994 was analyzed. Sex- and age-adjusted 5-year survival trends for 10 common cancers and for all cancers combined were es
This article discusses an emergent indigenous counter-discourse. on Lakota (Sioux) Indian history. This discourse challenges the widely accepted narrative of Lakota history that sets their date of arrival in the-Black Hills of South Dakota in the 18th century. Modern Lakota historians maintain that the Lakotas have always been in the sacred Black Hills and that the conventional narrative of the La
Multicolor karyotyping technologies, such as spectral karyotyping (SKY) (Schrock et al.1996; Liyanage et al. 1996) and multiplex (M-) FISH (Speicher et al. 1996), have proved to be extremely useful in prenatal, postnatal, and cancer cytogenetics. However, these technologies have inherent limitations that, in certain situations, may result in chromosomal misclassification. In this report, we presen
Pattern recognition is an integral part of the innate immune system. The human contact system has been shown to interact with the surface of many bacterial and fungal pathogens, and once activated leads to the generation of antimicrobial peptides and the proinflammatory mediator bradykinin. Here we show that apart from these surfaces also neutrophil extracellular traps (NETs) provide a surface tha
A combined paleomagnetic and Ar-40/Ar-39 study was carried out along eight stratigraphically overlapping sections in the Oligocene Afro-Arabian flood volcanic province in Yemen (73 sites). The composite section covers the entire volcanic stratigraphy in the sampling region and represents five polarity zones that are correlated to the geomagnetic polarity time scale based on Ar-40/Ar-39 ages from t
A recently introduced silicon microextraction chip (SMEC), used for on-line proteomic sample preparation, has proved to facilitate the process of protein identification by sample clean up and enrichment of peptides. It is demonstrated that a novel grid-SMEC design improves the operating characteristics for solid-phase microextraction, by reducing dispersion effects and thereby improving the sample
Deep brain stimulation (DBS) is associated with significant improvement of motor complications in patients with severe Parkinson's disease after some 6-12 months of treatment. Long-term results in a large number of patients have been reported only from a single study centre. We report 69 Parkinson's disease patients treated with bilateral DBS of the subthalamic nucleus (STN, n = 49) or globus pall
Radiopaque cement containing barium sulfate causes significantly more bone resorption in vivo and in vitro than radiolucent cement. The aim of this study was to investigate the osteolytic potential of an alternative radiopaque agent, triphenyl bismuth (TPB). Bone cement particles containing various concentration of TPB (15 and 25 wt%) prepared by two methods, blending and dissolution, were added t
In recent years, systematic searches of both prokaryote and eukaryote genomes have identified a staggering number of small RNAs, the biological functions of which remain unknown. Small RNA-based regulators are well known from bacterial plasmids. They act on target RNAs by sequence complementarity; that is, they are antisense RNAs. Recent findings suggest that many of the novel orphan RNAs encoded
We present a result on the global existence of classical solutions for quasilinear parabolic systems with homogeneous Dirichlet boundary conditions in bounded domains with a smooth boundary. Our method relies on the use of Lyapunov functions.
The fecal microbiota of two healthy Swedish infants was monitored over time by terminal restriction fragment length polymorphism (T-RFLP) analysis of amplified 16S rRNA genes. Principal component analysis (PCA) of the T-RFLP profiles revealed that the fecal flora in both infants was quite stable during breast-feeding and a major change occurred after weaning. The two infants had different sets of
This paper investigates efficiency properties of profit-maximizing non-linear outlay schedules. It demonstrates that some well-known efficiency characteristics of the profit-maximizing non-linear outlay schedule may not continue to hold when the single-crossing condition is relaxed.
