Heller Madsen, Henrik Dam, Ida Hageman
BACKGROUND: Light plays a crucial role in both the pathogenesis and treatment of seasonal affective disorder (SAD). Consequently decreased retinal sensitivity to light has been suggested to be a risk factor for SAD. In a population of persons with severe visual impairment we recently found a highly increased prevalence of SAD. We now aimed to identify eye disorders or anatomical locations with specific association to seasonality. METHODS: In 912 cases (33%) from our prior seasonal pattern assessment questionnaire (SPAQ) screening study, we retrieved eye diagnoses from the Danish National Patient Registry and analyzed for specific eye disorders or anatomical locations that significantly differentiated SPAQ outcomes (global seasonality score, (GSS) and SPAQ-SAD prevalence)...

Increased ambient concentration of particulate matters are considered as one of major causes for increased prevalence or exacerbation of asthma or asthma like symptoms. Recently, possible temporal variation in risks of PM on mortality has been suggested. We investigated short-term effect of both PM10 and PM2.5 on asthma hospitalization, and assessed temporal variation of PM risks in Seoul, Korea, 2003-2011. Generalized additive model was used to estimate PM risks on asthma hospitalization with consideration by long-term trend, influenza epidemic, day of week, meteorological factors...

The aim of the study was to determine the response of metallicolous and nonmetallicolous Echium vulgare L. populations to chronic multi-metal (Zn, Pb, Cd) and acute Zn (200, 400 μM) and Pb (30, 60 μM) stress. Three populations of E. vulgare, one from uncontaminated and two from metal-contaminated areas, were studied. Two types of experiments were performed - a short-term hydroponic experiment with acute Zn or Pb stress and a long-term manipulative soil experiment with the use of soils from the sites of origin of the three populations...

With an increasing number of large-scale population-based cardiac magnetic resonance (CMR) imaging studies being conducted nowadays, there comes the mammoth task of image annotation and image analysis. Such population-based studies would greatly benefit from automated pipelines, with an efficient CMR image analysis workflow. The purpose of this work is to investigate the feasibility of using a fully-automatic pipeline to segment the left ventricular endocardium and epicardium simultaneously on two orthogonal (vertical and horizontal) long-axis cardiac cine MRI scans...

BACKGROUND: Orofacial clefts (OFCs), including nonsyndromic cleft lip with or without cleft palate (NSCL/P), are common birth defects. NSCL/P is highly heterogeneous with multiple phenotypic presentations. Two common subtypes of NSCL/P are cleft lip (CL) and cleft lip with cleft palate (CLP) which have different population prevalence. Similarly, NSCL/P can be divided into bilateral and unilateral clefts, with unilateral being the most common. Individuals with unilateral NSCL/P are more likely to be affected on the left side of the upper lip, but right side affection also occurs...

The development of a digestive system is an essential feature of bilaterians. Studies of the molecular control of gut formation in arthropods have been studied in detail in the fruit fly Drosophila melanogaster. However, little is known in other arthropods, especially in noninsect arthropods. To better understand the evolution of arthropod alimentary system, we investigate the molecular control of gut development in the spider Parasteatoda tepidariorum (Pt), the primary chelicerate model species for developmental studies...

Due to a large and growing collection of genomic and experimental resources, Brachypodium distachyon has emerged as a powerful experimental model for the grasses. To add to these resources we sequenced 21,165 T-DNA lines, 15,569 of which were produced in this study. This increased the number of unique insertion sites in the T-DNA collection by 21,078 bringing the overall total to 26,112. Thirty seven percent (9,754) of these insertion sites are within genes (including UTRs and introns) and 28% (7,217) are within 500 bp of a gene...

Odorant receptors (ORs) expressed in the antennae of parasitoid wasps are responsible for detection of various lipophilic airborne molecules. In the present study, 107 novel OR genes were identified from Microplitis mediator antennal transcriptome data. Phylogenetic analysis of the set of OR genes from M. mediator and Microplitis demolitor revealed that M. mediator OR (MmedOR) genes can be classified into different subfamilies, and the majority of MmedORs in each subfamily shared high sequence identities and clear orthologous relationships to M...

BACKGROUND: TOR1A has been proposed as an important genetic factor in early-onset isolated dystonia. Variants located in the 3' untranslated region of TOR1A are of particular importance because they may influence gene expression, although related studies are limited. The objectives of the present study focused on variants in the TOR1A 3' untranslated region. METHODS: The last exon of TOR1A was sequenced in 229 cases with isolated dystonia and in 210 controls. In addition, 471 controls were tested to determine the frequency of the variants in the 3' untranslated region...

The use of systemic corticosteroids (SC) for the treatment of psoriasis is not recommended according to textbooks and guidelines. In clinical practise, however, many physicians frequently prescribe SC for patients with psoriasis. To determine the magnitude of SC prescription for outpatients with psoriasis in Korea and identify factors associated with the use of SC, we used the 2010-2014 nationwide claims data of the Health Insurance Review and Assessment Service of Korea. In frequency analysis for the full scale of prescribed SC, oral methylprednisolone was the most frequently prescribed SC, followed by dexamethasone and betamethasone injections...

AIMS: Heart failure (HF) is frequent in type 2 diabetes (T2D) and several glucose-lowering medications may increase HF risk. In the SAVOR-TIMI trial, patients on Saxagliptin experienced a 27% higher risk of hospitalisation for HF (HHF). In a retrospective study on 127,555 patients, we showed that DPP-4i therapy was associated with a lower HHF risk than sulphonylurea (SU) therapy. We herein re-analyzed such data to evaluate intraclass differences among DPP-4i and SU. MATERIALS AND METHODS: We included T2D patients initiating DPP-4i or SU alone or in combination with metformin...

AIMS: Metformin is renally excreted and has been associated with the development of lactic acidosis. Although current advice is to omit metformin during illnesses that may increase risk of acute kidney injury (AKI), the evidence supporting this is lacking. We investigated the relationship between AKI, lactate concentrations and the risk of lactic acidosis in those exposed to metformin. METHODS: We undertook a population-based case-control study of lactic acidosis in 1,746 participants with Type 2 diabetes and 846 individuals without diabetes with clinically measured lactates with and without AKI between 1994-2014...
