Physiological and transcriptomic analysis dissects the molecular mechanism governing meat quality during postmortem aging in Hu sheep ().

Introduction: Hu sheep, known for its high quality and productivity, lack fundamental scientific research in China.

Methods: This study focused on the effects of 24 h postmortem aging on the meat physiological and transcriptomic alteration in Hu sheep.

Results: The results showed that the 24 h aging process exerts a substantial influence on the mutton color, texture, and water content as compared to untreated group.

Up-Conversion Luminescence and Temperature Sensing of Er/Yb Codoped YLuO Solid Solution.

In this paper, Er/Yb codoped YLuO solid solution was prepared through the sol-gel method, and the substitution of Y by Lu ions in YO was confirmed by X-ray diffraction data. The up-conversion emissions of samples under 980 nm excitation and the relative up-conversion processes are investigated. The emission shapes do not vary with the change in doping concentration due to the unaltered cubic phase.

Age-related habitat selection by brown forest skinks (Sphenomorphus indicus).

In reptiles, habitat selection is the process whereby suitable habitat is selected that optimizes physiological functions and behavioral performance. Here, we used the brown forest skink (Sphenomorphus indicus) as a model animal and examined whether the frequency of active individuals, environmental temperature, illumination of activity area, and habitat type vary with different age classes. We surveyed the number of active individuals and measured environmental variables at Baiyunshan Mountain in Lishui, Zhejiang, China.
