The main danger of cold stress to animals in cold regions is systemic metabolic changes and protein synthesis inhibition. RBM3, an exceptional cold shock protein, is rapidly upregulated in response to hypothermia to resist the adverse effects of cold stress. However, the mechanism of the protective effect and the rapid upregulation of RBM3 remains unclear.

Methods: The information of 26,293 Asian-American patients diagnosed with PCa between 2004 and 2015 were extracted from the SEER 18 database. Subjects were divided into three groups: died of PCa, died of other causes, survival based on the outcomes at the end of 155 months' follow-up.
Newborn poultry in cold regions often suffer from cold stress, causing a series of changes in their physiology and metabolism, leading to slow growth and decreased production performance. However, a single anti-stress substance cannot completely or maximally eliminate or alleviate the various effects of cold stress on animals. Therefore, the effects of the supplemented glutamine and L-carnitine on broilers under low temperature were evaluated in this study.

Cold exposure can easily lead to cold stress, slow growth and even death of newborn animals. O-GlcNAcylation modification can act as type of "stress receptor" and"nutrition sensor" in a variety of stress responses, however, it is not clear how O-GlcNAcylation can regulate glucose metabolism in the liver of piglets under cold stress.

O-GlcNAcylation is an atypical, reversible, and dynamic glycosylation that plays a critical role in maintaining the normal physiological functions of cells by regulating various biological processes such as signal transduction, proteasome activity, apoptosis, autophagy, transcription, and translation. It can also respond to environmental changes and physiological signals to play the role of "stress receptor" and "nutrition sensor" in a variety of stress responses and biological processes. Even, a homeostatic disorder of O-GlcNAcylation may cause many diseases.

The present study aimed to investigate the possible effects of CIRP-mediated regulation of glucose metabolism in the liver following acute cold exposure. The livers and serum of male C57BL/6 mice were collected following cold exposure at 4 °C for 0 h, 2 h, 4 h, and 6 h.

In this study, the expression of heat shock protein 70 (HSP70), Toll-like receptor 4 (TLR4), bone marrow differentiation factor 88 (MYD88), and phosphorylated nuclear factor-κB (NF-κB) was consistent with fluctuations in insulin in fasted cold-exposed mice. We also found up-regulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) in acute cold exposure with a decrease in core body temperature.

To further understand the effects of prenatal cold stress on offspring, we investigated the behavior change; the expression of glucocorticoid receptor (GR), mineralocorticoid receptor (MR), brain-derived neurotrophic factor (BDNF), insulin-like growth factor 1 receptor (IGF1R), neuronal nuclei (NEUN), glial fibrillary acidic protein (GFAP), corticotropin-releasing hormone receptor 1 (CRHR1), Gamma-aminobutyric acid B receptor, 2 (GABAB2) proteins in hippocampus; the ratio of CD4/CD8 lymphocyte subsets and the level of norepinephrine (NE), dopamine (DA) in the peripheral blood of weaned offspring rats using behavioral tests and biology analysis methods. The results showed that prenatal cold stress affected offspring HPA axis activity, inhibited the expression of MR, BDNF and IGF1R in the hippocampus of male offspring, and lowered the expression of GR in female offspring.

Protein -linked β--acetylglucosamine glycosylation (-GlcNAcylation) regulates many biological processes. Studies have shown that -GlcNAc modification levels can increase during acute stress and suggested that this may contribute to the survival of the cell. This study investigated the possible effects of -GlcNAcylation that regulate glucose metabolism, apoptosis, and autophagy in the liver after acute cold stress.

In this study, we report a new bacteria-detection strategy that can recognize bacteria quickly and directly by surface-enhanced Raman scattering (SERS) with the formation of well-defined bacteria-aptamer@AgNPs. SERS signals generated by bacteria-aptamer@AgNPs exhibited a linear dependence on bacteria (R = 0.
