Association Between Changes in Habitual Physical Activity and Changes in Bone Density, Muscle Strength, and Functional Performance in Elderly Men and Women

To investigate the long-term effects of habitual physical activity on changes in musculoskeletal health, functional performance, and fracture risk in elderly men and women. Ten-year prospective population-based study. Malmo-Sjobo Prospective Study, Sweden. Participants were 152 men and 206 women aged 50, 60, 70, and 80 who were followed for 10 years. Distal radius bone mineral density (BMD) (singl

Molecular phylogeny of the speciose vole genus Microtus (Arvicolinae, Rodentia) inferred from mitochondrial DNA sequences

Voles of the genus Microtus represent one of the most speciose mammalian genera in the Holarctic. We established a molecular phylogeny for Microtus to resolve contentious issues of systematic relationships and evolutionary history in this genus. A total of 81 specimens representing ten Microtus species endemic to Europe as well as eight Eurasian, six Asian and one Holarctic species were sequenced

Evaluation of the Incredible Years Series - An open study of its effects when first introduced in Sweden

Behaviour management problems (BMP) are common among children (4-12%) and the prevalence seems to be rising. Persistent antisocial behaviour often leads to poor long-term psychosocial adjustment. Structured parent-training programmes have proven to be the most effective way of treating BMP in young children. The Incredible Years Series (IYS), which is a manual-based programme, was introduced in Sw

Estimating the number of components with defects post-release that showed no defects in testing

Components that have defects after release, but not during testing, are very undesirable as they point to 'holes' in the testing process. Either new components were not tested enough, or old ones were broken during enhancements and defects slipped through testing undetected. The latter is particularly pernicious, since customers are less forgiving when existing functionality is no longer working t

Identification of collagen-induced arthritis loci in aged multiparous female mice.

Collagen-induced arthritis in mice is one of the most commonly used autoimmune experimental models, with many similarities to rheumatoid arthritis. Since collagen-induced arthritis is a complex polygenic disease there is a need for identification of several major disease-controlling genes. Because rheumatoid arthritis particularly affects aged women, we have in the present study identified new gen

Integrative analysis for finding genes and networks involved in diabetes and other complex diseases

We have developed an integrative analysis method combining genetic interactions, identified using type l diabetes genome scan data, and a high-confidence human protein interaction network. Resulting networks were ranked by the significance of the enrichment of proteins from interacting regions. We identified a number of new protein network modules and novel candidate genes/ proteins for type 1 dia

Pressure autoregulation, intracranial pressure, and brain tissue oxygenation in children with severe traumatic brain injury

Object. Cerebral pressure autoregulation is an important neuroprotective mechanism that stabilizes cerebral blood flow when blood pressure (BP) changes In this study the authors examined the association between autoregulation and clinical factors. BR. intracranial pressure (ICP), brain tissue oxygen tension (PbtO(2)), and outcome after pediatric severe traumatic brain injury (TBI). In particular w

Financial assurance and mine closure: Stakeholder expectations and effects on operating decisions

Financial assurance is increasingly seen as a means to ensure orderly, clean and lasting closure of mines. Broadly interpreted, "closure" requires leaving viable ecosystems on mining lands that are compatible with a healthy environment and with human activities, that have low hazard, and that encompass measures to prevent ongoing pollution from the site in the long-term. Financial assurance encomp

Serum S100B and hypothermic circulatory arrest in adults

BACKGROUND: Cerebral injury is the most important complication of cardiac operations with cardiopulmonary bypass. Prolonged total circulatory arrest (TCA) can expose patients to an even greater risk of cerebral injury. We sought to detect the degree of cerebral injury in adults who had thoracic aortic operations with TCA by measuring S100B protein, which is released into the circulation after cere

Red supergiants as potential Type IIn supernova progenitors: Spatially Resolved 4.6 Mum CO Emission Around VY CMa and Betelgeuse

We present high-resolution 4.6 mu m CO spectra of the circumstellar environments of two red supergiants (RSGs) that are potential supernova (SN) progenitors: Betelgeuse and VY Canis Majoris (VY CMa). Around Betelgeuse, (CO)-C-12 emission within +/-3 '' (+/-12 km s(-1)) follows a mildly clumpy but otherwise spherical shell, smaller than its similar to 55 '' shell in KI lambda 7699. In stark contras

On the role of the axial ligand in heme proteins: a theoretical study

We present a systematic investigation of how the axial ligand in heme proteins influences the geometry, electronic structure, and spin states of the active site, and the energies of the reaction cycles. Using the density functional B3LYP method and medium-sized basis sets, we have compared models with His, His+Asp, Cys, Tyr, and Tyr+Arg as found in myoglobin and hemoglobin, peroxidases, cytochrome

FDG PET studies during treatment: Prediction of therapy outcome in head and neck squamous cell carcinoma.

BACKGROUND: Positron emission tomography (PET) provides metabolic information of tissues in vivo. The purpose of this study was to assess the value of PET with 2-[(18) F] fluoro-2-deoxy-D-glucose (FDG) in prediction of therapy outcome (tumor response, survival, and locoregional control) in locally advanced HNSCC. METHODS: Between 1993 and 1999 47 patients underwent PET before (PET(1)) and after (P

An extract of Uncaria tomentosa inhibiting cell division and NF-kappaB activity without inducing cell death.

Previous reports have demonstrated that extracts of the plant Uncaria tomentosa inhibit tumor cell proliferation and inflammatory responses. We have confirmed that C-Med 100®, a hot water extract of this plant, inhibits tumor cell proliferation albeit with variable efficiency. We extend these findings by showing that this extract also inhibits proliferation of normal mouse T and B lymphocytes and

Decreased UCP2 mRNA expression in rat stomach following vagotomy: novel role for UCP2 as free radical scavenger in the stomach?

Uncoupling protein 2 (UCP2) is a protein, located in the inner mitochondrial membrane, which dissipates the proton gradient of this membrane and uncouples respiration from oxidative phosphorylation. We found, by in situ hybridisation, UCP2 mRNA to be located in the proliferating zone of the mucous neck cells in the fundus part of the rat stomach. We also found that UCP2 expression in fundus was si

Divalent metal transporter 1 is involved in amyloid precursor protein processing and A{beta} generation.

The amyloid-beta precursor protein (APP) and its pathogenic byproduct beta-amyloid peptide (Abeta) play central roles in the pathogenesis of Alzheimer's disease (AD). Reduction in levels of the potentially toxic Abeta is one of the most important therapeutic goals in AD. Recent studies have shown that bivalent metals such as iron, copper, and zinc are involved in APP expression, Abeta deposition,
