Sb-Doped Steel Halide Nanocrystals: Any 0D vs . 3D Evaluation.
These results suggest that Eda has a protective effect on the mitochondrial fusion disruption induced by MPP+ in PC12 cells. The mechanism may be related to the up-regulation of OPA1/MFN2 and down-regulation of DRP1.Androgen plays an important role in singing of songbirds. Recent studies have shown that androgen levels in vivo not only affect the external morphology of songbirds, but also affect their singing behavior. Androgens (including derivatives) affect singing behavior and singing system in many ways. Based mainly on the results from our research group in the zebra finch, this review summarizes the effects of androgen on singing behavior, excitability and synaptic transmission of projection neurons of singing system, and the interaction of androgen with other neurotransmitter receptors in the brain of songbirds.Gliomas are malignant tumors with strong invasiveness. The current treatment strategy is surgical treatment assisted by a variety of radiotherapies, chemotherapies and immunotherapies. However, the curative efficacy is limited. Adrenergic receptor (AR) is an important stress hormone receptor, which is highly involved in the regulation of the tumorigenesis and progression of various tumors by activating different downstream signal transduction pathways. Recent studies have shown that AR is dysregulated in glioma cells and tissues, and plays an important role in a series of biological behaviors such as tumorigenesis, invasion and metastasis of glioma. This article reviews the research progress of AR in the field of glioma in recent years, which provides a theoretical basis for the prevention and treatment of glioma targeting the AR.Adrenergic receptor (AR), one of the key receptors for nervous system, plays an important role in the immune microenvironment and the progression of many diseases. In recent years, the regulation of ARs and its signal on macrophages has become a research hotspot. Researchers found that ARs could exert different regulatory functions on macrophages in different microenvironments, which in turn affects occurrence and development of diseases such as tumor, heart failure, obesity, acute injury, infection and pregnancy-related diseases. This review summarizes the expression and functional regulation of ARs on macrophages, and the role of ARs in microenvironment of related diseases, which might provide new ideas for the treatments.Synaptic cell adhesion molecules (CAMs) are a type of membrane surface glycoproteins that mediate the structural and functional interactions between pre- and post-synaptic sites. Synaptic CAMs dynamically regulate synaptic activity and plasticity, and their expression and function are modulated by environmental factors. Synaptic CAMs are also important effector molecules of stress response, and mediate the adverse impact of stress on cognition and emotion. In this review, we will summarize the recent progress on the role of synaptic CAMs in stress, and aim to provide insight into the molecular mechanisms and drug development of stress-related disorders.The mitochondrial respiratory chain supercomplex (mitoSC) is a complex super-assembly formed by free complexes on the mitochondrial inner membrane respiratory chain through the interaction between their subunits, mainly including mitoSCI1+III2+IV1-4, mitoSCI1+III2, mitoSCIII2+IV1-2, high molecular weight mitoSC (HMW mitoSC) and mitochondrial metacomplex (mitoMC). mitoSC has been shown to improve the efficiency of electron transport in the respiratory chain and reduce the production of reactive oxygen species. The species and content of mitoSC change in different tissues in aging and many mitochondria-related diseases. By summarizing the structure and function of mitoSC in different tissues of human and mammals, and the changes of mitoSC under conditions of aging, heart disease, type 2 diabetes, cancer and genetic defects, this review focuses on the effects of exercise on mitoSC and its related regulation mechanisms in order to offer an insight for exercise interventions in mitochondria-related diseases.Endoplasmic reticulum (ER) is an important organelle for protein folding, post-transcriptional modification and transport, which plays an important role in maintaining cell homeostasis. A variety of internal and external environmental stimuli can cause the accumulation of misfolded or unfolded proteins in the endoplasmic reticulum, and then result in ER stress. ER stress activates the unfolded protein response (UPR) and initiates a cluster of downstream signals to maintain ER homeostasis. However, severe and persistent ER stress activates UPR, which eventually leads to apoptosis and diseases. In recent years, a lot of researches suggest that ER stress plays an important role in the pathogenesis of various cardiovascular diseases (CVD), including ischemic heart disease, diabetic cardiomyopathy, heart failure, atherosclerosis and vascular calcification, high blood pressure and aortic aneurysm. ER stress might be one of the important targets for treatment of multiple CVD. Herein, the regulation mechanism of ER stress by activating UPR pathways in various common CVD and the new research advances in relationship of ER stress and CVD are briefly reviewed.Long-term exposure to high altitude affects spatial working memory. Previous studies have focused on the analysis of electroencephalogram (EEG) components in time domain rather than in frequency domain. Amenamevir To explore the influence of long-term high altitude exposure on time dynamic characteristics and neural oscillation process of the spatial working memory, n-back task combined with the technology of event related potential recording was performed on 20 young migrants who grew at low altitude before the age of 18 and moved to high altitude more than three years ago, and 21 young people who had never been to the high altitude. EEG data were recorded, and the time domain and frequency domain analyses were performed. The results showed that the response time was longer and the accuracy rate was lower under the 2-back condition in the high altitude group compared with those in low altitude group. The late positive potential (LPP) amplitude was more negative, P2 amplitude was more positive in the 2-back condition, and the power value of early delta frequency band (1-4 Hz, 160-300 ms) was larger, while the power values of late delta frequency band (1-4 Hz, 450-650 ms) and theta frequency band (4-8 Hz, 450-650 ms) were smaller in the high altitude group compared with those in low altitude group.
