Abstract:
... The prevalence of artificial lights not only improves the lighting conditions for modern society, but also poses kinds of health threats to human health. Although there are regulations and standards concerning light pollution, few of them are based on the potential contribution of improper lighting to diseases. Therefore, a better understanding of the health threats induced by light pollution may ...

Abstract:
... Light rare earth elements (LREEs) have been long used in agriculture (i.e., mainly via aerially applied LREE fertilizers) based on the fact that low-dose LREEs promote plant growth. Meanwhile, the toxic effects of low-dose LREEs on organisms have also been found. However, the cellular and molecular mechanism of low-dose LREEs acting on organisms remain unclear. Plants are at the beginning of food ...

Abstract:
... The efficiency of reactive oxygen species (ROS)-based photodynamic therapy (PDT) is far from satisfactory, because cancer cells can adapt to PDT by upregulating glutathione (GSH) levels. The GSH levels in tumor cells are determined based on glutamine availability via alanine-serine-cysteine transporter 2 (ASCT2)-mediated entry into cells. Herein, we develop co-assembled nanoparticles (PPa/V-9302 N ...

Abstract:
... NAC transcription factors (TFs) play an important role in the plant resistant response to biotic and abiotic stresses. However, the functions of the most NAC TFs are still unknown, especially in tomato. Here, we identified and functionally characterized an NAC TFs, SlNAP1, in tomato, and found that SlNAP1 was significantly induced by salt stress. Under 150 mM NaCl treatments, morphological indexes ...

Abstract:
... Currently, graphene quantum dots (GQDs) are widely used as antibacterial agents, and their effects are dependent on the reactive oxygen species (ROS) generated by photodynamic and peroxidase activities. Nevertheless, the supply of substrates or light greatly limits GQDs application. Besides, due to compensatory mechanisms in bacteria, comprehensive analysis of the molecular mechanism underlying th ...
... Iron (Fe) is a micronutrient for plant development, as constituent of several photosynthesis- and respiration-related proteins and enzymes. Consequently, Fe deficiency leads to chlorosis in leaves and plant growth impairment. It has become increasingly evident that light signals coordinate iron homeostasis in plants. To further address new insights into how light is a fundamental part of Fe defici ...
... Intestinal tissue functions in innate immunity to prevent the entry of harmful substances, and to maintain homeostasis through the constant proliferation of intestinal stem cells (ISC). To understand the mechanisms which regulate ISC in response to gut damage, we identified 81 differentially expressed genes (DEGs) through RNA-seq analysis after oral administration of three intestinal-damaging subs ...
... In our previous study, two crude polysaccharides from red kidney bean and small black soybean (RK, SB) have shown the alleviative effect on type 2 diabetic mice. Meanwhile, hepatic dysfunction usually accompanied with type 2 diabetes mellitus (T2DM), and closely related to glucose and lipid homeostasis. Therefore, this time we further investigated the protective effect on hepatic dysfunction of RK ...

Abstract:
... Phthalate esters (PAEs) are ubiquitous environmental contaminants, arising growing public concern. Nevertheless, information on the exposure and risks of PAEs in wildlife remains limited. Here, we conducted the first investigation of the occurrences, spatiotemporal trends, and potential risks of twelve metabolites of PAEs (mPAEs) in 74 humpback dolphins from the northern South China Sea during 200 ...

Abstract:
... Many per- and polyfluoralkyl substances (PFASs) may disrupt maternal thyroid hormone homeostasis in pregnancy. Concerns should be raised regarding the PFASs exposure in pregnant women because thyroid hormones are involved in the early development of the fetus. In this study, we measured the concentrations of 13 PFASs, including five novel short-chain PFASs, in serum from 123 pregnant women in Beij ...
... Transcriptional regulator PRD1-BF-1-RIZ1 homology (PR) domain containing protein-16 (PRDM16) has a fundamental function in maintaining energy homeostasis and regulating glucose and lipid metabolism, which are responsible for the development of type 2 diabetes (T2D). However, the impact of genetic variation of PRDM16 gene on T2D risk remains to be investigated. Thus, we evaluated the possible assoc ...
... Nanotechnology has revealed profound possibilities for the applications in applied sciences. The nanotechnology works based on nanoparticles. Among nanoparticles, silver nanoparticles largely introduced into aquatic environments during fabrication. Which cause severe contamination in the environment specially in freshwater fish. Therefore, the current study was a pioneer attempt to use the animal ...

Abstract:
... The cardiometabolic effects of air pollution in the context of mixtures and the underlying mechanisms remain not fully understood. This study aims to investigate the joint effect of air pollutant mixtures on a broad range of cardiometabolic parameters, examine the susceptibility of obese individuals, and determine the role of circulating fatty acids. In this panel study, metabolically healthy norm ...

Abstract:
... Soil Cd pollution seriously threatens environment and human health. Due to its ability to absorb and accumulate Cd in mycelia, Stropharia rugosoannulata could be a potential candidate for bioremediation of Cd-contaminated soils; however, the response mechanism of mycelia to Cd stress is still unclear. In this study, the physiologic and proteomic differences of S. rugosoannulata mycelia under 0.2 m ...
... Evidence from in vitro and rodent studies suggests that organophosphate esters (OPEs) may disrupt sex steroid hormone homeostasis, but no human studies, to date, have examined the effects of in utero exposure to OPEs on offspring reproductive development. Anogenital distance (AGD) is a sensitive biomarker of fetal hormonal milieu and has been used to assess reproductive toxicity. We evaluated the ...

Abstract:
... As a conserved protein degradation system, autophagy plays important roles in removing or degrading misfolded and denatured proteins to maintain the homeostasis in cells. As a core member of autophagy, the involvement of ATG8 in plant tolerance to abiotic stress is paid more attention. In this study, by the SMART online tool, the Atg8 conserved domain was detected in CaATG8e, and by the MEGA11 sof ...

Abstract:
... The rapid expansion of aquaculture has led to increased demand for protein sources for feed production. Lipids and carbohydrates can serve as energy sources and induce a “protein-sparing” effect. However, excessive dietary lipids and carbohydrates may cause lipid accumulation in the liver, impair immune and antioxidant capacities, thus hidering the growth and meat quality of farmed fish. Bile acid ...

Abstract:
... Global climate warming has drawn worldwide attention. However, the health impact of heat exposure is still controversial. This study aimed to explore the exact effects and sex differential vulnerability under intermittent heat exposure (IHE) patterns and tried to elucidate the potential mechanisms by which IHE modulated hepatic lipid and glucose homeostasis. Both female and male C57BL/6 N mice wer ...

Abstract:
... Cypermethrin (CYP), a prototypical synthetic pyrethroid, reportedly causes metabolic disruption, while its stereoselective impact remains elusive. This study initially revealed that only α-CYP caused significant weight loss at 8.5 mg/(kg•day) in rats. All three CYP isomers caused the accumulation of hepatic glycogen, and hyperlipemia phenotype as the increment of total triglyceride. Rats treated w ...
... Decabromodiphenyl ethane (DBDPE), a new brominated flame retardant, could negatively affect neurobehavior and pose health risks to humans. Humans are also exposed to widely used nanomaterials. This study investigated the combined toxic effects and action types of DBDPE and Zinc oxide nanoparticles (ZnO NPs) on human neuroblastoma SK-N-SH cells and the toxicity mechanisms. DBDPE inhibited the viabi ...
