Background: The view of delirium has changed considerably over the last decade, and delirium is now a very topical issue within the intensive care unit (ICU) setting. Delirium has proved to be common in critically ill patients and is manifested as acute changes in mental status with reduced cognitive ability, incoherent thought patterns, impaired consciousness, agitation and acute confusion. In or

BACKGROUND/AIMS: Characteristics of primary amphetamine, heroin and cocaine users were compared in a criminal justice population. METHODS: 7,085 clients with suspected or reported substance use were studied using the Addiction Severity Index. Variables separating amphetamine, heroin and cocaine users were analyzed in stepwise logistic regression. RESULTS: There were considerably more primary amphe

Theory predicts that, during pollen competition, selection may favor a pollen trait that increases donor competitive ability at the expense of the female reproductive function. One such pollen trait could be manipulation of the onset of stigma receptivity. We evaluated the potential occurrence of this kind of sexual conflict by testing female control of the timing of stigma receptivity in the self

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 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

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

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

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

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

For a long time, reactive oxygen species (ROS) produced by the phagocyte NADPH oxidase (NOX2) complex have been considered harmful mediators of inflammation owing to their highly reactive nature. However, there are an increasing number of findings suggesting that ROS produced by the NOX2 complex are anti-inflammatory and prevent autoimmune responses, thus challenging existing dogma. ROS might not

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

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

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

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

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

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
