Body Temperature Regulation in Domestic Dogs After Agility Trials: The Effects of Season, Training, Body Characteristics, Age, and Genetics.

An animal's body mass is said to be indirectly related to its rate of heat loss; that is, smaller animals with higher surface area to volume tend to lose heat faster than larger animals. Thus, thermoregulation should be related to body size, however, generalizable patterns are still unclear. Domestic dogs are a diverse species of endothermic mammals, including a 44-fold difference in body size.

Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scales are increasingly needed to capture transient, out-of-equilibrium phenomena. We present a novel pump-probe photon-electron method within a scanning transmission electron microscope (STEM) to map temperature dynamics with unprecedented spatial and temporal resolutions.

Introduction: Fibromyalgia has a high female predominance and research work has been focussing mainly on women.
Objectives: We aimed to answer (1) gender differences in pain scores and quality of life, (2) any gender-specific subgroups defined by quantitative sensory testing (QST), and (3) correlations of QST parameters with pain intensity and questionnaire scores.
Methods: We evaluated clinical presentations and QST profiles from 38 male and 38 age-matched female patients.

Low temperatures are one of the critical conditions affecting the performance and distribution of plants. Exposure to cooling results in the reprogramming of gene expression, which in turn would be mediated by epigenetic regulation. Antarctica is known as one of the most severe ecosystems, but several climate models predict an increase in average temperature, which may positively impact the development of Antarctic plants; however, under warmer temperatures, plants' vulnerability to damages from low-temperature events increases.

Emulsions play an important role in food systems by encapsulating and delivering active compounds, but maintaining their stability under various conditions can be challenging. This study explored how the concentrations of Tremella polysaccharides (TPs) (0-0.75 %) affects the structural of whey protein isolate (WPI) and the stability of their emulsions at pH 4.
