Fluorescence imaging of light absorption for axial-beam geometry in capillary electrophoresis

A new method for investigation of axial-beam absorption detection for improved detection limits in microcolumn separations is reported. The method is based on fluorescence imaging of light absorption along a separation capillary. The probing UV light is introduced at one end of the capillary and shows an exponential fall-off along the capillary. As the UV light propagates through the sample peaks,

Fast or fair? A study of response times

This paper uses a modified dictator game to investigate the relationship between response times and social preferences. We find that faster subjects more often chose the option with the highest payoff for themselves. Moreover, our within-analysis reveals that, for a given individual, payoff maximizing choices are reached quicker than choices expressing social preferences

Outcome in a Prospective Phase II Trial of Medically Inoperable Stage I Non-Small-Cell Lung Cancer Patients Treated With Stereotactic Body Radiotherapy.

PURPOSE: The impact of stereotactic body radiotherapy (SBRT) on 3-year progression-free survival of medically inoperable patients with stage I non-small-cell lung cancer (NSCLC) was analyzed in a prospective phase II study. PATIENTS AND METHODS: Fifty seven patients with T1NOMO (70%) and T2N0M0 (30%) were included between August 2003 and September 2005 at seven different centers in Sweden, Norway,

Surviving Overwhelming Challenges: Family Caregivers' Lived Experience of Caring for a Child Diagnosed with HIV and Enrolled in Antiretroviral Treatment in Ethiopia.

Family caregivers play a critical role in caring for children living with HIV, however, there is little knowledge about their experiences. The aim of this study was to illuminate the family caregivers' lived experiences of caring for a child when he or she has been diagnosed with HIV and enrolled to antiretroviral treatment. Qualitative interviews with 21 family caregivers of 21 children diagnosed

Impact of a short home-based yoga programme on blood pressure in patients with hypertension: a randomized controlled trial in primary care.

The present study was designed to evaluate yoga's impact on blood pressure (BP) and quality of life (QOL) and on stress, depression and anxiety in patients with hypertension in a primary care setting. We conducted a multi-centre randomized controlled trial with follow-up after 12-week intervention completion. Adult primary care patients diagnosed with hypertension were randomly allocated to yoga o

Global H3K27 trimethylation and EZH2 abundance in breast tumor subtypes.

Polycomb repressive complex 2 (PRC2) and its core member enhancer of zeste homolog 2 (EZH2) mediate the epigenetic gene silencing mark: trimethylation of lysine 27 on histone 3 (H3K27me3). H3K27me3 is characteristic of the chromatin at genes involved in developmental regulation in undifferentiated cells. Overexpression of EZH2 has been found in several cancer types such as breast, prostate, melano

The Intensive Care Delirium Screening Checklist: translation and reliability testing in a Swedish ICU.

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

Characteristics of primary amphetamine users in Sweden: a criminal justice population examined with the Addiction Severity Index.

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

Pollen donor identity affects timing of stigma receptivity in Collinsia heterophylla (Plantaginaceae): a sexual conflict during pollen competition?

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

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
