Humeral Head Resurfacing in the Rheumatoid Shoulder

Summary: The rheumatoid shoulder and elbow should be assessed in an early stage concerning the possibility of surgical intervention. The cause of the shoulder pain can be localized elsewhere in the shoulder girdle or in the neck. In patients with glenohumeral pain, resurfacing of the humeral head with a cup seems to be a good alternative to conventional stemmed prostheses. It diminishes the risk o

Microwave detection at 110 GHz by nanowires with broken symmetry

By using arrays of nanowires with intentionally broken symmetry, we were able to detect microwaves up to 110 GHz at room temperature. This is, to the best of our knowledge, the highest speed that has been demonstrated in different types of novel electronic nanostructures to date. Our experiments showed a rather stable detection sensitivity over a broad frequency range from 100 MHz to 110 GHz. The

High soil carbon efflux rates in several ecosystems in southern Sweden

Soil C effluxes were measured at five forest stands with different vegetation and a meadow in southeastern Sweden (57¡5«N, 16¡7«E). Exponential regressions of soil respiration against air and soil temperatures were used to model soil respiration at forests stands. For the meadow, a light response curve with gross primary production (GPP) against PAR and a cubic regression with GPP against air temp

Mycophenolate mofetil, azathioprine and cyclophosphamide enhanced efficacy combined with cyclosporine in rat cardiac transplantation

Anti-proliferative drugs have been used for immunosuppression since the introduction of clinical transplantation. Most transplant centres include azathioprine (Aza) and cyclosporine (CyA) in their standard regimens, despite several controlled studies having failed to confirm the benefit of this combination. Aza is still. the most commonly used anti-proliferative drug, although no major differences

Molecular analysis of Philadelphia-positive childhood chronic myeloid leukemia.

The breakpoints in chromosome 22 were determined in five children with Philadelphia-positive chronic myeloid leukemia. All had rearrangements within the major breakpoint cluster region (M-bcr). Four patients had breakpoints in the 5' region of M-bcr (zones 1-3), whereas one had a rearrangement in the 3' region (zone 4). The patient with the 3' rearrangement was the only one to develop a lymphoid b

Carotenoids from tomatoes inhibit heterocyclic amine formation

Tomatoes are a rich source of antioxidants; and they are commonly used for meat cooking in Mediterranean countries. The effects of tomato antioxidants on the formation of carcinogenic/mutagenic heterocyclic amines were investigated. A liquid model system containing as precursors creatinine, glucose and glycine in molar concentrations comparable to those present in bovine meat (chemical model syste

Habitual Physical Activity and Vascular Aging in a Young to Middle-Age Population at Low Cardiovascular Risk.

Background and Purpose - Regular endurance exercise has been shown to reduce the age-related increase in arterial stiffness that is thought to contribute to cardiovascular risk. The aim of this study was to evaluate the influence of age and habitual physical activity on carotid artery wall thickness and stiffness in a population of young to middle-age subjects at low cardiovascular risk. Methods -

ULTRASOUND STUDIES ON PELVIC FLOOR PHYSIOLOGY AND OBSTETRIC PERINEAL TEARS

Despite repair such tears may result in anal and urinary incontinence and prolapses of the pelvic floor, problems in need of surgical repair later in life. Descriptions of the structures injured during vaginal delivery and their topographic relations in the perineum are missing in most textbooks. Trans

Growth of ectomycorrhizal mycelia and composition of soil microbial communities in oak forest soils along a nitrogen deposition gradient

Deciduous forests may respond differently from coniferous forests to the anthropogenic deposition of nitrogen (N). Since fungi, especially ectomycorrhizal (EM) fungi, are known to be negatively affected by N deposition, the effects of N deposition on the soil microbial community, total fungal biomass and mycelial growth of EM fungi were studied in oak-dominated deciduous forests along a nitrogen d

Management of bile duct calculi : a study with special reference to long-term outcome

Popular Abstract in Swedish Mellan 15 och 20 % av de patienter som kommer för behandling av gallstenssjukdomen (stenar i gallblåsan) har samtidigt stenar i de djupa gallvägarna (förbindelsegången mellan lever-gallblåsa och tolvfingertarmen). Hos yngre patienter är andelen endast 7-8 %, medan den i äldre patientgrupper kan vara 50 % eller mer. Traditionellt har stenarna i gallgången avlägsnats samtOpen surgical versus endoscopic treatment of CBD stones in 80 elderly not cholecystectomized patients revealed a similar efficacy of stone clearance and early major complication rates, as well as total complication rates and hospitalization time in the two groups during 5 to 9 years follow-up. However, more patients in the endoscopically treated group died from heart disease, suggesting surgery to

On speed stability

Distributed energy resources, such as wind turbine generators, often employ induction generators. When such a generator is subjected to a nearby fault, its rotor may accelerate and reach high steady-state speed far from that corresponding to the frequency of the system. This is the generator counterpart to induction motor stalling, which is classified as voltage stability. The phenomenon is a matt

Exploring the impacts of the tropical Pacific SST on the precipitation patterns over South America during ENSO periods

Summary Previous studies on precipitation over South America that strongly support the existence of links between precipitation and SST anomalies in the Pacific Ocean have identified specific regions where the ENSO signal is particularly stronger. Northeast of Brazil and some parts of southern South America are examples of these regions. However, the same attention was not taken to identify which

Interaction of recombinant human cystatin C with the cysteine proteinases papain and actinidin

The interaction between recombinant human cystatin C and the cysteine proteinases papain and actinidin was studied by spectroscopic, kinetic and equilibrium methods. The absorption, near-u.v.c.d. and fluorescence-emission difference spectra for the cystatin C-proteinase interactions were all found to be similar to the corresponding spectra for chicken cystatin. The kinetics of binding of cystatin

CD46 in meningococcal disease

The human-specific bacterial pathogen Neisseria meningitidis is a major cause of sepsis and/or meningitis. The pili of N. meningitidis interact with CD46, a human cell-surface protein involved in regulation of complement activation. Transgenic mice expressing human CD46 were susceptible to meningococcal disease, because bacteria crossed the blood-brain barrier in these mice. Development of disease
