Climate change impact assessments are plagued with uncertainties from many sources, such as climate projections or the inadequacies in structure and parameters of the impact model. Previous studies tried to account for the uncertainty from one or two of these. Here, we developed a triple-ensemble probabilistic assessment using seven crop models, multiple sets of model parameters, and eight contrasting climate projections together to comprehensively account for uncertainties from these three important sources...

OBJECTIVE: Immune dysfunction is an important component of the disease process underlying Systemic Sclerosis (SSc), but the mechanisms contributing to altered immune cell function in SSc remain poorly defined. Here, we measured the expression and function of the co-inhibitory receptors (co-IRs) PD-1, TIGIT, TIM-3, and LAG-3 in lymphocyte subsets from the peripheral blood of SSc patients. METHODS: Co-IR expression levels on immune cell subsets were analyzed using a 16-color flow cytometry panel...

Simulation of blood flows in the pulmonary artery provides some insight into certain diseases by examining the relationship between some continuum metrics, e.g. the wall shear stress acting on the vascular endothelium, which responds to flow-induced mechanical forces by releasing vasodilators/constrictors. In [?kheyfets2015patient], V. Kheyfets studies numerically a patient-specific pulmonary circulation to show that decreasing wall shear stress is correlated with increasing pulmonary vascular impedance. In this paper, we develop a scalable parallel algorithm based on domain decomposition methods to investigate an unsteady model with patient specific pulsatile waveforms as the inlet boundary condition...

Rheumatoid arthritis (RA) is a chronic inflammatory disorder characterized by infiltration of the joint synovium by activated inflammatory cells. CD4+ T cells form a large proportion of the inflammatory cells invading the synovial tissue, and are involved in the RA pathological process. In general, CD4+ T cells differentiate into various T helper (Th) cell subsets and acquire the functional characterization to respond to specific pathogens, and also mediated some autoimmune disorders such as RA. Because the differentiation of Th cell subsets is determined by the expression of specific transcription factors in response to cytokine environment, these transcription factors is considered to have a role in pathology of RA...

Microplastics (plastics < 5 mm, including nanoplastics which are < 0.1 μm) originate from the fragmentation of large plastic litter or from direct environmental emission. Their potential impacts in terrestrial ecosystems remain largely unexplored despite numerous reported effects on marine organisms. Most plastics arriving in the oceans were produced, used, and often disposed on land. Hence, it is within terrestrial systems that microplastics might first interact with biota eliciting ecologically relevant impacts...

Climate warming is substantially shifting the leaf phenological events of plants, and thereby impacting on their individual fitness and also on the structure and functioning of ecosystems. Previous studies have largely focused on the climate impact on spring phenology, and to date the processes underlying leaf senescence and their associated environmental drivers remain poorly understood. In this study, experiments with temperature gradients imposed during the summer and autumn were conducted on saplings of European beech to explore the temperature responses of leaf senescence...

We read with great interest the recent paper by Cohen et al regarding the early morphological and functional changes induced by intrauterine growth restriction on the heart and detected during echocardiography(1). In particular, the authors found increases in left ventricular sphericity and posterior and relative wall thicknesses. They also noted that the diastolic function, measured with tissue Doppler imaging, dropped. This article is protected by copyright. All rights reserved.

Background Results of epidemiologic studies are often reported in the media because they are of vital interest for many people. Using the example of meat consumption and colorectal cancer, we investigated whether results of epidemiologic studies are reported in an understandable and correct manner in German newspapers and magazines. Methods We gathered all articles published in 13 selected German newspapers and magazines that referred to a press release on meat consumption and colorectal cancer issued by the International Agency for Research on Cancer (IARC) on October 26th 2015...

Goals Despite numerous reported deficits and an increasingly tense working environment in German hospitals, employees themselves often assess their job satisfaction as being high to very high. Hence, the board of directors does not have important arguments for sustainable improvement of working conditions. This discrepancy between working conditions and subjective satisfaction was the motivation for this work. Methods Data were acquired via an attitude survey at the University Hospital for Children and Adolescents Leipzig, with employees sub-divided into medical, nursing and administrative/technical staff...

The meromictic Lake Cadagno is characterized by a compact chemocline with high concentrations of anoxygenic phototrophic purple sulfur bacteria (PSB) and green sulfur bacteria (GSB). The co-occurrence of phylogenetically distant bacterial groups such as PSB and GSB in the same ecological niche, makes the chemocline of Lake Cadagno an ideal system for studying the conditions and consequences of coexistence of photosynthetic bacteria populations. In this study, we applied flow cytometry (FCM) as a fast tool to identify metabolic changes due to the production and consumption of inclusion bodies such as sulfur globules (SGBs), and follow population dynamics of closely related anoxygenic photosynthetic sulfur bacteria in their natural environment...

Aptamers are molecules that reveal highly complex and refined molecular recognition properties. These molecules are capable of binding with high affinity and selectivity to targets, ranging from small molecules to whole living cells. Several aptamers have been selected for targeting cellular proteins and they have also used in developing therapeutics and diagnostic strategies. Epithelial cell adhesion molecule (EpCAM) is considered as a cancer stem cell (CSC) biomarker and one of the most promising targets for aptamer selection against CSCs...

Arsenic (As) remediation in contaminated water using nanoparticles is promising. However, the fate and transport of As associated with nano-adsorbents in natural environment is poorly understood. To investigate the fate of adsorbed As on nano-TiO2 in changed redox condition from oxic to anoxic, we added the As(V)-TiO2 suspension in groundwater to an autoclaved soil column which inoculated a sulfate-reducing bacterium, Desulfovibrio vulgaris DP4. The dissolved As(V) in effluent increased to 798 μg/L for the biotic column and to 1510 μg/L for the abiotic control, and dissolved As(III) was observed only in biotic column...

Chemicals in consumer products have become the focus of recent regulatory developments including California's Safer Consumer Products Act. However, quantifying the amount of chemicals released during the use and post-use phases of consumer products is challenging, limiting the ability to understand their impacts. Here we present a comprehensive framework, OrganoRelease, for estimating the release of organic chemicals from the use and post-use of consumer products given limited information. First, a novel Chemical Functional Use Classifier estimates functional uses based on chemical structure...

We engineered an automated biomechatronics system, MyoRobot, for robust objective and versatile assessment of muscle or polymer materials (bio-)mechanics. It covers multiple levels of muscle biosensor assessment, e.g. membrane voltage or contractile apparatus Ca2+ ion responses (force resolution 1µN, 0-10mN for the given sensor; [Ca2+] range ~ 100nM-25µM). It replaces previously tedious manual protocols to obtain exhaustive information on active/passive biomechanical properties across various morphological tissue levels...

This systematic review assessed the current state of the literature on sexually exploited boys internationally. We aimed to describe what is known about sexual exploitation of boys, identify gaps in the literature, provide implications for practice, and make recommendations for future research. Multiple database searches were conducted using a combination of controlled vocabulary and keywords to capture child and adolescent sexual exploitation. Our search identified 11,099 unique references and excluded studies that did not include male participants less than 18 years old or disaggregate results by relevant age groups and/or by sex...

Reactive oxygen species (ROS) are byproducts generated during normal cellular metabolism, and redox states have been shown to influence stem cell self-renewal and lineage commitment across phyla. However, the downstream effectors of ROS signaling that control stem cell behavior remain largely unexplored. Here, we used the Drosophila testis as an in vivo model to identify ROS-induced effectors that are involved in the differentiation process of germline stem cells (GSCs). In the Affymetrix microarray analysis, 152 genes were either upregulated or downregulated during GSC differentiation induced by elevated levels of ROS, and a follow-up validation of the gene expression by qRT-PCR showed a Spearman's rho of 0...
