Sleeping problems as a risk factor for subsequent musculoskeletal pain and the role of job strain: results from a one-year follow-up of the Malmö Shoulder Neck Study Cohort.

BACKGROUND: The role of sleeping problems in the causal pathway between job strain and musculoskeletal pain is not clear. Purpose: To investigate the impact of sleeping problems and job strain on the one-year risk for neck, shoulder, and lumbar pain. METHOD: A prospective study, using self-administered questionnaires, of a healthy cohort of 4,140 vocationally active persons ages 45-64, residing in

Fourier series for analysis of temporal sequences of satellite sensor imagery

Fourier Series and the derivative were used in this study for analysing time series of remotely-sensed data. The technique allows fundamental characteristics of time series data to be quantified. In Fourier analysis a function in space or time is broken down into sinusoidal components, or harmonics. The first and second harmonics are a function of the mono or bi-modality of the curve, demonstrated

Area-efficient configurable high-throughput signal detector supporting multiple MIMO modes

Abstract in UndeterminedThis paper presents a low-complexity, highthroughput,and configurable multiple-input multiple-output(MIMO) signal detector design solution targeting the emergingLong-Term-Evolution-Advanced (LTE-A) downlink. The detectorsupports signal detection of multiple MIMO modes, whichare spatial-multiplexing (SM), spatial-diversity (SD), and spacedivision-multiple-access (SDMA). Area

Platelet transcriptional profile and protein expression in patients with systemic lupus erythematosus: up-regulation of the type I interferon system is strongly associated with vascular disease.

Patients with systemic lupus erythematosus (SLE) have a markedly increased risk to develop cardiovascular disease, and traditional cardiovascular risk factors fail to account for this increased risk. We used microarray to probe the platelet transcriptome in individuals with SLE and healthy controls, and the gene and protein expression of a subset of differentially expressed genes was further inves

Tumefactive demyelinating disease treated with decompressive craniectomy.

Background: Tumefactive demyelinating disease (TDD) is a rare primary demyelinating disease with diagnostic and therapeutic challenges. Methods and results: We report a 50-year old woman with TDD successfully treated with decompressive craniectomy and corticosteroids. The patient presented with seizures, subacute progressive hemispheric syndrome, and a tumourlike abnormality on MRI. Demyelinating

The effects of achieving hypothermia early in a heterogeneous population of patients with cardiac arrest.

In a recent article Wolff et al. (2009) [1] present highly interesting results bearing on how timing of therapeutic hypothermia might affect outcome. However, some of their analyses are unadjusted for heterogeneities in the patient population, while others indicate a statistical model break-down. Moreover, the time from cardiac arrest to return of spontaneous circulation is recorded but not includ

Unilateral axonal or terminal injection of 6-hydroxydopamine causes rapid-onset nigrostriatal degeneration and contralateral motor impairments in the rat.

Unilateral injection of the catecholamine neurotoxin 6-hydroxydopamine into the axons or terminals of the nigrostriatal pathway is commonly used to model Parkinson's disease in experimental animals. Although the terminal lesion paradigm is considered to induce a more progressive lesion when compared to the axonal lesion, few studies have directly compared the early time-course for lesion developme

Visions and open challenges for a knowledge-based culturomics

The concept of culturomics was born out of the availability of massive amounts of textual data and the interest to make sense of cultural and language phenomena over time. Thus far however, culturomics has only made use of, and shown the great potential of, statistical methods. In this paper, we present a vision for a knowledge-based culturomics that complements traditional culturomics. We discuss

Human Retinal Development in an in situ Whole Eye Culture System.

Phenotypic characterization of human retinogenesis may be facilitated by use of the tissue culture system paradigm. Traditionally, most culture protocols involve isolation of retinal tissue and/or cells, imposing various degrees of trauma, which in many cases leads to abnormal development. In this paper, we present a novel culture technique using whole embryonic eyes to investigate whether the ret

Efficacy of mobile telephone contact for follow-up in injecting heroin users.

Background: Prospective follow-up of heroin users is known to be difficult due to their unstable lifestyle, and high follow-up rates have usually demanded major tracking efforts. In Sweden, mobile telephones are commonly used by heavy drug users for drug trading. Objectives: This methodology study aims to examine the efficacy of mobile telephone contact for prospective follow-up interviews with in

Trust and health: testing the reverse causality hypothesis.

Social capital research has consistently shown positive associations between generalised trust and health outcomes over 2 decades. Longitudinal studies attempting to test causal relationships further support the theory that trust is an independent predictor of health. However, as the reverse causality hypothesis has yet to be empirically tested, a knowledge gap remains. The aim of this study, ther

Generation of neutralizing antibodies and divergence of SIVmac239 in cynomolgus macaques following short-term early antiretroviral therapy.

Neutralizing antibodies (NAb) able to react to heterologous viruses are generated during natural HIV-1 infection in some individuals. Further knowledge is required in order to understand the factors contributing to induction of cross-reactive NAb responses. Here a well-established model of experimental pathogenic infection in cynomolgus macaques, which reproduces long-lasting HIV-1 infection, was

Cell Type Differentiation Dynamics in the Developing Porcine Retina.

The dynamics of retinal embryogenesis have been well characterized previously in terms of cell proliferation, genesis and migration, whereas overall cell type differentiation within the retinal layers has been less thoroughly explored. In the present study, phenotypical differentiation of all 7 major retinal cell types was examined in the developing porcine retina using one cell-specific immunohis

Dietary Shifts and Human Health: Cancer and Cardiovascular Disease in a Sustainable World.

INTRODUCTION: Increasing evidence suggests that optimal food choice is critical for sizable prevention of western diseases such as cardiovascular disease and cancer. The Mediterranean diet is an important step in this direction. Moreover, substantially lower rates of Western disease, even compared to Mediterranean countries, have been observed among hunter-gatherers and other non-western populatio

Changes in encoding of path of motion after acquisition of a second language

Languages vary typologically in their lexicalization of Path of motion (Talmy 1991). Furthermore, lexicalization patterns are argued to affect syntactic packaging at the level of the clause (e.g. Slobin 1996b) and tend to transfer from a first (L1) to a second language (L2) in second language acquisition (e.g. Cadierno 2004). From this crosslinguistic and developmental evidence, typological prefer

Genome-Wide Association Studies of the PR Interval in African Americans.

The PR interval on the electrocardiogram reflects atrial and atrioventricular nodal conduction time. The PR interval is heritable, provides important information about arrhythmia risk, and has been suggested to differ among human races. Genome-wide association (GWA) studies have identified common genetic determinants of the PR interval in individuals of European and Asian ancestry, but there is a

Superficial blood flow following photodynamic therapy of malignant non-melanoma skin tumours measured by laser Doppler perfusion imaging

Laser Doppler perfusion imaging offers a new modality for in vivo monitoring of the superficial blood perfusion in biological tissue, In this study, the superficial blood perfusion of malignant nonmelanoma skin tumours and the surrounding normal skin was measured in conjunction with photodynamic therapy (PDT) using topical delta-aminolaevulinic acid (ALA)-induced protoporphyrin IX as a photosensit
