Cellular mechanisms of hereditary photoreceptor degeneration – Focus on cGMP

The cellular mechanisms underlying hereditary photoreceptor degeneration are still poorly understood, a problem that is exacerbated by the enormous genetic heterogeneity of this disease group. However, the last decade has yielded a wealth of new knowledge on degenerative pathways and their diversity. Notably, a central role of cGMP-signalling has surfaced for photoreceptor cell death triggered by

Occurrence and habitat use of European eel (Anguilla anguilla) in running waters : lessons for improved monitoring, habitat restoration and stocking

To improve the management of the European eel (Anguilla anguilla) in freshwater, it is essential to define important lotic habitats. Electrofishing data from 289 wadeable, hard-bottom sites in 69 Swedish coastal rivers and streams, originally surveyed for salmonid monitoring, were used to evaluate the effects of sampling- and habitat-related factors on eel occurrence. Probability of eel occurrence

An fMRI-study on single-sided deafness : Spectral-temporal properties and side of stimulation modulates hemispheric dominance

Objective: Our main aim was to investigate the blood oxygenation level dependent (BOLD) response to monaural and binaural speech- and non-speech stimuli as measured with fMRI in subjects with single-sided deafness and in normal hearing controls. We hypothesised that the response to monaural stimulation in both normal hearing subjects and persons with single-sided deafness would vary with the compl

SinoPedia—A Linked Data Services platform for decentralized knowledge base

Knowledge bases are largely developed and utilized in academic and industrial fields, such as DBPedia, VIAF, LoC, Getty, and which are published in the Linked Data format. However, if you want to view different resources on these knowledge bases, you have to switch between different web pages from these resources. Therefore, we proposed a decentralized data hub named SinoPedia, which consists of s

Temporal hierarchies with autocorrelation for load forecasting

We propose four different estimators that take into account the autocorrelation structure when reconciling forecasts in a temporal hierarchy. Combining forecasts from multiple temporal aggregation levels exploits information differences and mitigates model uncertainty, while reconciliation ensures a unified prediction that supports aligned decisions at different horizons. In previous studies, weig

Why Low Levels of Democracy Promote Corruption and High Levels Diminish It

Theory predicts democracy should reduce corruption. Yet, scholars have found that while corruption is low at high levels of democracy, it is high at modest levels, as well as low when democracy is absent. A weakness of studies that aim to explain this inverted curvilinear relationship is that they do not disaggregate the complex concepts of democracy and corruption. By contrast, this paper disaggr

Features of urine S100B and its ability to rule out intracranial hemorrhage in patients with head trauma : a prospective trial

Purpose: Traumatic brain injury causes morbidity and mortality worldwide. S100B is the most documented emergency brain biomarker and its urine-assay might be advantageous because of easier sampling. The primary aim was to evaluate urine S100B’s ability to rule out intracranial hemorrhage. Secondary aims included S100B temporal pattern for 48 h post-trauma and chemical properties of urine that affe

Explaining the measurement and evaluation stasis : A thought experiment and a note on functional stupidity

Purpose: The purpose of this paper is to explain the “evaluation deadlock” or “stasis” diagnosed by many authors. The explanation relies on a thought experiment. Design/methodology/approach: The paper is conceptual and builds on a thought experiment inspired by qualitative research such as interviews with communication consultants in Sweden. It makes use of principal–agent theory and Akerlof’s the

Intimate partner violence and maternal depression during pregnancy : A community-based cross-sectional study in Ethiopia

Introduction Intimate partner violence (IPV) is regarded an important public health and human rights issue, characterized by physical, sexual or emotional abuse. Globally more than one in three women report physical or sexual violence by their intimate partners. Though the association between IPV and depression is known, we found no study investigating depression as a risk factor for IPV and very

Water Resources Management Through Flood Spreading Project Suitability Mapping Using Frequency Ratio, k-nearest Neighbours, and Random Forest Algorithms

Lack of water resources is a common issue in many countries, especially in the Middle East. Flood spreading project (FSP) is an artificial recharge technique, which is generally suggested for arid and semi-arid areas with two major aims including (1) flood mitigation and (2) artificial recharge of groundwater. This study implemented three state-of-the-art popular models including frequency ratio (

Application of alkylresorcinols in an organic apple orchard for protection against storage diseases

Each year, fungal storage diseases destroy large amounts of apple, especially in organic orchards. In the present study, antifungal activity of a rye bran-based remedy with 5-n-alkylresorcinols (ARs) was investigated. In 2014 and 2015, ‘Amorosa’ apple trees in an organic orchard were sprayed with a 0.025% AR emulsion pre-harvest, once or twice at different points in time. In addition, emulsions wi

Year-round distribution, activity patterns and habitat use of a poorly studied pelagic seabird, the fluttering shearwater Puffinus gavia

We present the first study to examine the year-round distribution, activity patterns, and habitat use of one of New Zealand’s most common seabirds, the fluttering shearwater (Puffinus gavia). Seven adults from Burgess Island, in the Hauraki Gulf, and one individual from Long Island, in the Marlborough Sounds, were successfully tracked with combined light-saltwater immersion loggers for one to thre

Split N and P addition decreases straw mineralization and the priming effect of a paddy soil : a 100-day incubation experiment

The effect of mineral fertilization and its application pattern on microbial activity and the subsequent CO2 and CH4 emissions arising from soil organic matter (SOM) or added substrate remains unclear. We quantified the decomposition of 13C-labeled straw and the priming effect (PE) governed by the N and P fertilizer application pattern during a 100-day experiment in a flooded soil. Straw addition

Driving Neuronal Differentiation through Reversal of an ERK1/2-miR-124-SOX9 Axis Abrogates Glioblastoma Aggressiveness

Identifying cellular programs that drive cancers to be stem-like and treatment resistant is critical to improving outcomes in patients. Here, we demonstrate that constitutive extracellular signal-regulated kinase 1/2 (ERK1/2) activation sustains a stem-like state in glioblastoma (GBM), the most common primary malignant brain tumor. Pharmacological inhibition of ERK1/2 activation restores neurogene

Impact of menstrual function on hormonal response to repeated bouts of intense exercise

Background: Strenous exercise stimulates the hypothalamic-pituitary (HP) axis in order to ensure homeostasis and promote anabolism. Furthermore, exercise stimulates a transient increase in the neurotrophin brain-derived neurotrophic factor (BDNF) suggested to mediate the anxiolytic effects of exercise. Athletes with secondary functional hypothalamic amenorrhea (FHA) have been reported to have lowe

B cell profiling in malaria reveals expansion and remodeling of CD11c+ B cell subsets

Humoral immunity is important in limiting clinical disease in malaria, yet the longitudinal B cell response to infection remains unclear. We performed a 1-year prospective study in patients treated for acute Plasmodium falciparum malaria for the first time or with previous exposure to the disease. Using an unbiased exploratory approach with mass cytometry, followed by targeted flow cytometry, we f

Spectroscopy of kaonic atoms at DAFNE and J-PARC

The interaction of antikaons (K) with nucleons and nuclei in the low-energy regime represents a very active research field in hadron physics. A unique and rather direct experimental access to the antikaon-nucleon scattering lengths is provided by precision X-ray spectroscopy of transitions in low-lying states in the lightest kaonic atoms (i.e. kaonic hydrogen and deuterium). In the SIDDHARTA exper

Evolutionary aspects of Indo-European gender assignment

Gender assignment in languages with a gender system is a complex issue, as this can be influenced by both semantic, morphological, and phonological factors (Corbett, 1991, 2013; Corbett & Fraser, 2000). Many Indo-European languages possess a three-gender system, which distinguishes masculine, feminine, and neuter gender. Whereas this system is preserved in several Indo-European branches, it ha
