The devil is in the details: identifying aspects of temperature variation that underlie sex determination in species with TSD.

Most organisms experience thermal variability in their environment; however, our understanding of how organisms cope with this variation is under-developed. For example, in organisms with temperature-dependent sex determination (TSD), an inability to predict sex ratios under fluctuating incubation temperatures in the field hinders predictions of how species with TSD will fare in a changing climate. To better understand how sex determination is affected by thermal variation, we incubated Trachemys scripta eg...

Barriers to Kidney Transplant-The Devil Is in the Details.

Individual and temporal variation in pathogen load predicts long-term impacts of an emerging infectious disease.

Emerging infectious diseases increasingly threaten wildlife populations. Most studies focus on managing short-term epidemic properties, such as controlling early outbreaks. Predicting long-term endemic characteristics with limited retrospective data is more challenging. We used individual-based modelling informed by individual variation in pathogen load and transmissibility to predict long-term impacts of a lethal, transmissible cancer on Tasmanian devil (Sarcophilus harrisii) populations. For this, we empl...

The Devil Is in the Microbial Genetic Details.

The work of Zeevi et al. (2019) in a recent issue of Nature shows that variations in gene content and organization between different strains of the same microbial species are widespread in the human gut microbiota and could be linked to many measures of health.

Structural and dynamical aspects of PEG/LiClO in solvent-mixtures via NMR spectroscopy.

Motivated by the potential usefulness of PEG/Li salt mixtures in several industrial applications, the structure and dynamics of PEG/LiClO mixtures has been investigated in D O and its mixtures with CD CN and DMSO-D6, in a series of PEG-based polymers with a wide variation in their molecular weights. H NMR chemical shifts, T /T relaxation rates, pulsed field gradient (PFG) NMR diffusion experiments, and 2D-HOESY NMR studies have been performed to understand the structural and dynamical aspects of these mixt...

Acclimation and adaptation components of the temperature dependence of plant photosynthesis at the global scale.

The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models (GVMs). The response may vary geographically, due to genetic adaptation to climate, and temporally, due to acclimation to changes in ambient temperature. Our goal was to develop a robust quantitative global model representing acclimation and adaptation of photosynthetic temperature responses. We quantified and modelled key mechanisms responsible for photosynthetic tempe...

United States State-Level Variation in the Use of Neuraxial Analgesia During Labor for Pregnant Women.

Neuraxial labor analgesia is recognized as the most effective method of providing pain relief during labor. Little is known about variation in the rates of neuraxial analgesia across US states. Identifying the presence and extent of variation may provide insights into practice variation and may indicate where access to neuraxial analgesia is inadequate.

Daily temperature variation magnifies the toxicity of a mixture consisting of a chemical pesticide and a biopesticide in a vector mosquito.

While many studies on the toxicity of pesticides looked at the effects of a higher mean temperature, effects of the realistic scenario of daily temperature variation are understudied. Moreover, despite the increasing interest for the toxicity of pesticide mixtures how this is influenced by temperature has been largely ignored. We tested whether daily temperature variation (DTV) magnifies the toxicity of two pesticides with a different mode of action, the organophosphate pesticide chlorpyrifos (CPF) and the ...

Capacity for survival in global warming: Adaptation of mesophiles to the temperature upper limit.

The Intergovernmental Panel on Climate Change recommends keeping the increase in temperature to less than a two-degree increase by the end of the century, but the direct impact of global warming on ecosystems including microbes has not been investigated. Here we performed thermal adaptation of two species and three strains of mesophilic microbes for improvement of the survival upper limit of temperature, and the improvement was evaluated by a newly developed method. To understand the limitation and variatio...

Seasonal and interpopulational phenotypic variation in morphology and sexual signals of Podarcis liolepis lizards.

Widespread species often show extensive phenotypic variation due to the contrasting abiotic and biotic factors that shape selective pressures in different environments. In this context, the gradual and predictable patterns of variation in climatic and environmental conditions found in mountain areas offer a great opportunity to explore intraspecific phenotypic variation. For instance, temperature is negatively correlated with altitude and virtually all aspects of the behavior and physiology of ectotherms ar...

Repeated exposure to temperature variation exacerbates airway inflammation through TRPA1 in a mouse model of asthma.

Studies from epidemiology suggest that ambient temperature is one of the underlying triggers and potential causes of asthma. The aim of this study was to examine the impact and the molecular mechanism of temperature-invoked airway inflammation using an experimental model of asthma in BALB/c mice.

Effects of temperature on amoebic gill disease development: Does it play a role?

A relationship between increasing water temperature and amoebic gill disease (AGD) prevalence in Atlantic salmon (Salmo salar) has been noted at fish farms in numerous countries. In Scotland (UK), temperatures above 12°C are considered to be an important risk factor for AGD outbreaks. Thus, the purpose of this study was to test for the presence of an association between temperature and variation in the severity of AGD in Atlantic salmon at 10 and 15°C. The results showed an association between temperature...

An Integrated Analysis of Metabolites, Peptides and Inflammation Biomarkers for Assessment of Pre-analytical Variability of Human Plasma.

Discrepancies in blood sample collection and processing could have a significant impact on levels of metabolites, peptides and protein biomarkers of inflammation in the blood, thus sample quality control is critical for successful biomarker identification and validation. In this study, we analyzed the effects of several pre-analytical processing conditions, including different storage times and temperatures for blood or plasma samples and different centrifugation forces, on the levels of metabolites, peptid...

Early-life environment and differences in costs of reproduction in a preindustrial human population.

Reproduction is predicted to trade-off with long-term maternal survival, but the survival costs often vary between individuals, cohorts and populations, limiting our understanding of this trade-off, which is central to life-history theory. One potential factor generating variation in reproductive costs is variation in developmental conditions, but the role of early-life environment in modifying the reproduction-survival trade-off has rarely been investigated. We quantified the effect of early-life environme...

Earliness Per Se by Temperature Interaction on Wheat Development.

Differences in time to heading that remain after photoperiod and vernalisation requirements have been saturated are classified as earliness per se (Eps) effects. It has been commonly assumed that Eps genes are purely constitutive and independent of environment, although the likely effect of temperature on Eps effects in hexaploid wheat has never been tested. We grew four near isogenic lines (NILs) for the Eps gene located in chromosome 1D (Eps-D1) at 6, 9, 12, 15, 18, 21 and 24 °C. In line with expectati...

Individual differences in visual attention and self-regulation: A multimethod longitudinal study from infancy to toddlerhood.

Given the importance of self-regulation for a broad range of developmental outcomes, identifying reliable precursors of self-regulation early in development is important for early prevention of developmental problems. The aim of this study was to examine whether three visual attention measures (fixation duration, variation in fixation duration, and disengagement) in infancy (9.10-11.43 months of age) predicted effortful control and compliance in toddlerhood (26.71-31.80 months). The sample consisted of ...

Simultaneous Observation of the Er- and Fe-Sublattice Magnetization of Ferrimagnetic Er_{3}Fe_{5}O_{12} in High Magnetic Fields Using X-Ray Magnetic Circular Dichroism at the Er L_{2,3} Edges.

X-ray magnetic circular dichroism (XMCD) studies at the Er L_{2,3} edges of Er_{3}Fe_{5}O_{12} exhibit a change of the spectral shape as a function of temperature and magnetic field. Using singular value decomposition, this variation is understood as a linear combination of two components. The dominating component is associated with the Er magnetization, while the second contribution is identified as an induced signal from the Fe sites. XMCD at either of the L edges in Er_{3}Fe_{5}O_{12} provides informatio...

The rheological behavior of microalgae slurry is a significant parameter affecting the performance of hydrothermal pretreatment reactors. Herein, the dynamic rheological behavior of microalgae slurry during hydrothermal pretreatment was investigated for the first time. The results revealed that the insoluble organics released from microalgae cells was the main factor affecting the rheolo...

The ERBB-STAT3 Axis Drives Tasmanian Devil Facial Tumor Disease.

The marsupial Tasmanian devil (Sarcophilus harrisii) faces extinction due to transmissible devil facial tumor disease (DFTD). To unveil the molecular underpinnings of this transmissible cancer, we combined pharmacological screens with an integrated systems-biology characterization. Sensitivity to inhibitors of ERBB tyrosine kinases correlated with their overexpression. Proteomic and DNA methylation analyses revealed tumor-specific signatures linked to the evolutionary conserved oncogenic STAT3. ERBB inhibit...

Impact of spatial variations in water quality and hydrological factors on the food-web structure in urban aquatic environments.

Global aquatic ecosystems are essential to human existence and have deteriorated seriously in recent years. Understanding the influence mechanism of habitat variation on the structure of the food-web allows the effective recovery of the health of degraded ecosystems. Whereas most previous studies focused on the selection of driving habitat factors, the impact of habitat variation on the food-web structure was rarely studied, resulting in the low success rate of ecosystem restoration projects globally. This ...

A metabolomic investigation into the temperature-dependent virulence of Pseudomonas plecoglossicida from large yellow croaker (Pseudosciaena crocea).

Pseudomonas plecoglossicida is associated with multiple fish diseases, and temperature is one of the most important environmental factors related to its outbreak. To elucidate the influence of temperature variation on the pathogen, the global metabolomics of P. plecoglossicida (NZBD9) were analysed at the virulent (18°C) and avirulent (12°C and 28°C) temperatures. The result showed that the levels of Phosphoric acid, Tyrosine, Spermidine and Sucrose were significantly reduced,while Itaconic acid, Gluc...
