BACKGROUND: Trials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to show if daily oral fluoxetine for 6 months after stroke improves functional outcome in an ethnically diverse population.

METHODS: AFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial done in 43 hospital stroke units in Australia (n=29), New Zealand (four), and Vietnam (ten). Eligible patients were ...

Structural protein 4.1, which has crucial interactions within the spectrin-actin lattice of the human red cell membrane skeleton, also is widely distributed at diverse intracellular sites in nucleated cells. We previously showed that 4.1 is essential for assembly of functional nuclei in vitro and that the capacity of 4.1 to bind actin is required. Here we report that 4.1 and actin colocalize in mammalian cell nuclei using fluorescence microscopy and, by higher-resolution ...

PURPOSE. This study seeks to characterize corneal functions and complications in a streptozocin (STZ)-induced rat model of type I diabetes mellitus (DM) and to understand the pathogenesis of diabetic keratopathy. METHODS. DM was induced via STZ injection in Sprague-Dawley rats. Body weight, length, and corneal size were measured and compared with the age-matched normal controls. Corneal morphology and histology were evaluated with slit lamp, digital confocal microscopy and hematoxylin ...

AIM: The present study aimed to assess the benefits of two-stent techniques for patients with DEFINITION criteria-defined complex coronary bifurcation lesions.

METHODS AND RESULTS: In total, 653 patients with complex bifurcation lesions at 49 international centres were randomly assigned to undergo the systematic two-stent technique (two-stent group) or provisional stenting (provisional group). The primary endpoint was the composite of target lesion failure (TLF) at the 1-year follow-up, ...

BACKGROUND: Prostate cancer is the most commonly diagnosed malignancy in men in Sweden and Geneva, and the third most common in men in Singapore. This population-based study describes trends in the incidence and mortality rates of prostate cancer in Singapore, Sweden and Geneva (Switzerland) from 1973 to 2006 and explores possible explanations for these different trends.

METHODS: Data from patients diagnosed with prostate cancer were extracted from national cancer registries in Singapore ...

BACKGROUND: We previously described a t(2;11)(p21;q23) chromosomal translocation found in patients with myelodysplasia or acute myeloid leukemia that leads to over-expression of the microRNA miR-125b, and we showed that transplantation of mice with murine stem/progenitor cells overexpressing miR-125b is able to induce leukemia. In this study, we investigated the mechanism of myeloid transformation by miR-125b.

DESIGN AND METHODS: To investigate the consequences of miR-125b ...

This study investigates the sensitivity of on-street parking demand using the automatic transaction data from parking pay stations obtained before and after a parking rate change that was implemented in Seattle in early 2011. The parking rate implementation is based on performance-based pricing where rates are increased, decreased, or not changed in neighborhoods with occupancy levels higher than, lower than, or within the desired level. We calculated the price elasticity of on-street ...

Children with neurodevelopmental disorders are at increased risk for sleep issues, which affect quality of life, cognitive function, and behavior. To determine the prevalence of sleep problems in children with the common neurodevelopmental disorder neurofibromatosis type 1, a cross-sectional study was performed on 129 affected subjects and 89 unaffected siblings, age 2 to 17 years, using the Sleep Disturbance Scale for Children questionnaire. Children with neurofibromatosis type 1 were ...

BACKGROUND: Early rehospitalization after kidney transplantation (KTx) is common and is considered a quality metric. Recipient and donor risk factors for early readmission after KTx are well studied. Little data exist on discharge-level factors associated with readmission.

METHODS: We performed a single-center, retrospective cohort study between 2011 and 2015 of adult KTx recipients to examine readmission indication, risk factors, and opportunities for reduction.

RESULTS: Of 462 KTxs, ...

This study examines the connection between the built environment, perceived safety from crime and walking behaviour by conducting a travel survey in King County, Washington State, U.S. and employing a two-stage least squares model. We seek to answer two research questions: how does the built environment affect perceived safety from crime and walking behaviour; and how does one’s perception of safety from crime affect his/her walking behaviour. Our results show that the built environment ...

Currently, traditional immunochemistry technologies such as enzyme-linked immunosorbent assays (ELISA) are the predominant analytical tool used to measure levels of recombinant proteins expressed in genetically engineered (GE) plants. Recent advances in agricultural biotechnology have created a need to develop methods capable of selectively detecting and quantifying multiple proteins in complex matrices because of increasing numbers of transgenic proteins being coexpressed or "stacked" ...

The Middle Paleozoic Maksyutov Complex is an important component of the Eurasian collisional orogeny. It consists of dominant mica-rich garnet schist and mica-poor quartzofeldspathic gneiss enclosing minor mafic eclogite boudins (unit no. 1). Employing Raman spectroscopy, we identified three cuboidal microdiamond inclusions (~2-3 micrometers in diameter) in garnet hosts from two different mica-poor gneissic samples. Broad spectral bands and high magnification SEM images suggest that the ...

Ambient assisted living (AAL) technologies can provide assistance and support to persons with dementia. They might allow them the possibility of living at home for longer whilst maintaining their comfort and security as well as offering a way towards reducing the huge economic and personal costs forecast as the incidence of dementia increases worldwide over coming decades. However, the development, introduction and use of AAL technologies also trigger serious ethical issues. This paper ...

The idea of using transit-oriented development (TOD) in reducing automobile dependency and improving the sustainability of transportation activities has gained wider support in recent years. Research findings have shown that residents living in TOD neighborhood used transit more frequently than people having similar socio-economic characteristics but living elsewhere. Most of the existing studies on TOD and transit ridership used recently developed sites or suburban neighborhoods as case ...

Objectives: We aim to determine the prevalence of vision impairment (VI) and its cumulative impact on multimorbidity, frailty, physical and cognitive function, and quality of life. Method: In all, 780 community-dwelling older adults were interviewed for demographic data and a one-off physical activity screening. Covariate measurements include vision via Snellen chart, multimorbidity, five-item FRAIL (Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight) scale and Mini-Mental ...
