Temperature as a driver for the expansion of the microalga Gonyostomum semen in Swedish lakes

Gonyostomum semen (Ehrenb) Diesing is a bloom-forming and noxious phytoplankton species, that usually occurs in brown-water lakes and which is often referred to as an invasive species. The aim of our study was to analyze changes over time in the occurrence and distribution of blooms, and to find possible drivers of this change. We also performed spatial analyses to identify environmental factors c

Transcriptional regulation of lineage commitment - a stochastic model of cell fate decisions.

Molecular mechanisms employed by individual multipotent cells at the point of lineage commitment remain largely uncharacterized. Current paradigms span from instructive to noise-driven mechanisms. Of considerable interest is also whether commitment involves a limited set of genes or the entire transcriptional program, and to what extent gene expression configures multiple trajectories into commitm

On a TiNiSi-Type Superstructure: Synthesis, Crystal and Electronic Structures of CaAgGe and Its Mn-Substituted Derivative

The compound CaAgGe and its Mn-substituted derivative CaMn0.07Ag0.93Ge were synthesized by reaction of the element mixtures at high temperature. Their structures were refined from single-crystal X-ray diffraction data. CaAgGe crystallizes in the isomorphic (i(3)) superstructure of the TiNiSi type (CaCuGe type). The LMTO band structure calculations predicted the CaAgGe phase to be metallic. In addi

Quantifying the Semantic Representations of Adolescents' Memories of Positive and Negative Life Events

We quantified the semantic content in adolescents’ descriptions of positive and negative life events and studied how these descriptions are related to the assessment Subjective Well-Being (SWB) at two points in time. The semantic content of the descriptions was quantified by Latent Semantic Analysis (LSA). LSA is a computational method based on algorithms stemming from computational linguistics, w

Healthcare matching - Conditions for developing a New Service System in Healthcare’

Purpose The purpose is to outline the conditions for a new service system in healthcare, which will be able to match the available capacity in and between healthcare units in order to match the need of care for the patients. Methodology By drawing on statements from patients, experiences from similar services (a literature review), empirical research into the effects of the reforms on free choice

Clinical issues in inhibitors

Anamestic inhibitors represent the major complication of haemophilia therapy now that clotting factor concentrates are virtually free of pathogen-transmission risk. Conventional clotting factor replacement is usually insufficient to prevent or treat bleeding in a haemophilia patient with a high responding inhibitor so that alternative treatment with bypassing agents is required. Despite their rela

Toluene diisocyanate: Induction of the autotaxin-lysophosphatidic acid axis and its association with airways symptoms.

Diisocyanates are industrial chemicals which have a wide range of applications in developed and developing countries. They are notorious lung toxicants and respiratory sensitizers. However, the mechanisms behind their adverse effects are not adequately characterized. Autotaxin (ATX) is an enzyme producing lysophosphatidic acid (LPA), and the ATX-LPA axis has been implicated in lung related inflamm

The transcription factors E2A and HEB act in concert to induce the expression of FOXO1 in the common lymphoid progenitor

Recent studies have identified a number of transcriptional regulators, including E proteins, EBF1, FOXO1, and PAX5, that act together to orchestrate the B-cell fate. However, it still remains unclear as to how they are linked at the earliest stages of B-cell development. Here, we show that lymphocyte development in HEB-ablated mice exhibits a partial developmental arrest, whereas B-cell developmen

Detecting region transitions for human augmented mapping

In this paper, we describe a concise method for the feature-based representation of regions in an indoor environment and show how it can also be applied for door-passage-independent detection of transitions between regions to improve communication with a human user.

Forest water use and water use efficiency at elevated CO2: a model-data intercomparison at two contrasting temperate forest FACE sites

Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed

Prevalence of stenoses and occlusions of brain-supplying arteries in young stroke patients.

OBJECTIVE: Atherosclerosis is believed to be a minor cause of TIA and stroke in younger and middle-aged patients. However, data from large cohorts are limited. This study investigates the prevalence of extracranial and intracranial atherosclerosis in stroke and TIA patients aged 18-55 years in the multinational sifap1 study. METHODS: From the sifap1 cohort (n = 5,023), we analyzed a subset of pati

Patatin-like phospholipase domain-containing 3 (PNPLA3) I148M (rs738409) affects hepatic VLDL secretion in humans and in vitro

Background & Aims: The robust association between non-alcoholic fatty liver disease (NAFLD) and the genetic variant I148M (rs738409) in PNPLA3 has been widely replicated. The aim of this study was to investigate the effect of the PNPLA3 I148M mutation on: (1) hepatic secretion of very low density lipoproteins (VLDL) in humans; and (2) secretion of apolipoprotein B (apoB) from McA-RH 7777 cells

Note on off-shell relations in nonlinear sigma model

In this note, we investigate relations between tree-level off-shell currents in nonlinear sigma model. Under Cayley parametrization, all odd-point currents vanish. We propose and prove a generalized U(1) identity for even-point currents. The off-shell U(1) identity given in [1] is a special case of the generalized identity studied in this note. The on-shell limit of this identity is equivalent wit

Evidence for altered inflammatory and repair responses in symptomatic carotid plaques from elderly patients.

Most acute cardiovascular events are caused by rupture of an atherosclerotic plaque. The incidence of cardiovascular events increases with age and inflammation is generally considered to be the main cause of increased plaque vulnerability. However, the relationship between age and plaque inflammation has not yet been fully clarified. The aim of our study was to determine if age-dependent plaque vu

Wideband SAW-Less Receiver Front-End with Harmonic Rejection Mixer in 65-nm CMOS

A wideband direct-conversion receiver front-end featuring a new harmonic rejection technique is demonstrated in 65-nm CMOS. The circuit consists of a two-stage low-noise amplifier, the first stage with capacitive feedback, a harmonic rejection mixer using 25% and 50% duty cycle local oscillator signals, and a third-order channel-select filter with configurable bandwidth. The receiver front-end is

Fertility Defects in Mice Expressing the L68Q Variant of Human Cystatin C A ROLE FOR AMYLOID IN MALE INFERTILITY

Background: The L68Q variant of cystatin C is highly amyloidogenic forming aggregates in individuals with HCCAA. Results: Spermatozoa from mice expressing human L68Q cystatin C exhibit fertility defects and increased levels of amyloid. Conclusion: L68Q epididymal fluid containing cystatin C amyloid is harmful for sperm function. Significance: Amyloid in the reproductive tract may contribute to mal
