The main advantages of Telemedicine in Tailored Protection against Heart diseases (CVD): A Systematic Assessment.
The data reassumed in this work are very useful for interdisciplinary researchers that work in a team to find the basic available information about all the aspects connected with this pandemic (from virus diffusion mechanism to health information, from economic and social impacts to measures to reduce the pandemic spread), with great attention to social acceptance of restriction measures and of vaccines (that currently results to be insufficient to achieve community immunity). Then, this review paper highlights the fundamental role of the trans-multi-disciplinary research that is devoted not only to understand the basics of the pandemic to propose solutions but has also the commitment to find strategies to increase population resilience. For this aim, the authors strongly suggest the establishment of an international health-care trans-multi-disciplinary workforce devoted to investigate, mitigate, and control also future viral events.With climate change, understanding and assessing the impact of climate variations on non-stationary changes of streamflow is of importance in the hydrologic and atmospheric sciences. In this study, tempo-spatial and scaling effects in the impacts of 18 climate variations on nonstationary streamflow for 279 watersheds across Canada are explored. Specifically, the change point and trends of streamflow are examined through Pettitt's test and Mann-Kendall test. Spatial patterns of correlations between the climate variations and flow rates over Canada, especially their non-stationarity, are investigated at seasonal and decadal scales. The patterns are also quantified by seven spatial classification algorithms under method uncertainty. A series of findings regarding the impacts are revealed. For instance, nonstationary changes of streamflow exist for approximately 9% of Canadian watersheds and most of them are located in Prairie Provinces and the eastern coast. The Atlantic Multidecadal Oscillation, Niño 12, Niño 3, Niño 4, and Niño 3.4 pose significant impacts on Canadian streamflow, which vary with watersheds and seasons. The impacts are closely associated with human activities, e.g., significant impacts of climate variations on populated-area streamflow over Canada. check details Different climatic variations have different time-varying effects on streamflow. All watersheds have obvious clustering characteristics and four spatial patterns are identified, which is insensitive with classification algorithm. These findings are conducive to understanding the hydrological impacts of atmospheric circulation and enhancing the reliability of hydrological prediction.Status epilepticus (SE) is a neurological emergency. The pathological hallmark of neuronal damage after epileptic seizures could be the chain reaction of oxygen free radicals. Hydroxylated fullerenes (HFs) are novel and effective free radical scavengers, which play an important role in various neurological diseases. However, whether they have a protective effect against epileptic seizures remains elusive. Our study explores the effect of pretreatment with HFs in different doses (0.5, 5, and 10 mg/kg) on SEmodels induced by pilocarpine (PILO). The results suggest that HFs have a protective effect on SE in a dose-dependent manner. HFs significantly reduce the incidence of SE, prolong the latency to SE, reduce the malondialdehyde (MDA) levels, and increase the glutathione (GSH) and superoxide dismutase (SOD) levels. In addition, HFs significantly raise the expression of B-cell lymphoma-2 (Bcl-2) and reduce the expression of Bcl-2-associated X protein (Bax). We found that expressions of nuclear NF-E2-related factor 2 (nNrf2), heme oxygenase-1 (HO-1) and NADPH quinone oxidoreductase-1 (NQO1) were upregulated 24 h after the onset of SE, but the increase was not enough to combat oxidative stress damage, nor to attenuate lipid peroxidation and apoptosis. The expressions of these proteins in HFs pretreatment groups increased more significantly than those in the epilepsy (EP) group, which effectively reduced lipid peroxidation and apoptosis in the hippocampus. In summary, these findings highlight that HFs pretreatment has a protective effect against PILO-induced SE in rats. It may relieve oxidative stress damage by activating the Nrf2-ARE signaling pathway. It provides evidence that fullerene derivatives may have therapeutic potential for epileptic seizures.Excitation-inhibition imbalance of GABAergic interneurons is predisposed to develop chronic temporal lobe epilepsy (TLE). We have previously shown that virtually every neuronal nitric oxide synthase (nNOS)-positive cell is a GABAergic inhibitory interneuron in the denate gyrus. The present study was designed to quantify the number of nNOS-containing hilar interneurons using stereology in pilocapine- and kainic acid (KA)-exposed transgenic adult mice that expressed GFP under the nNOS promoter. In addition, we studied the properties of miniature excitatory postsynaptic current (mEPSC) and paired-pulse response ratio (PPR) of evoked EPSC in nNOS interneurons using whole cell recording techniques. Results showed that there were fewer nNOS-immunoreactive interneurons of chronically epileptic animals. Importantly, patch-clamp recordings revealed reduction in mEPSC frequency, indicating diminished global excitatory input. In contrast, PPR of evoked EPSC following the granule cell layer stimulation was increased in epileptic animals suggesting reduced neurotransmitter release from granule cell input. In summary, we propose that impaired excitatory drive onto hippocampal nNOS interneurons may be implicated in the development of refractory epilepsy.
The vascular component of the hand-arm-vibration syndrome (HAVS) is often characterized by vibration-induced white fingers (VWF). Active substances secreted by the vascular endothelial cells (VEC) maintain a dynamic balance but damage to the blood vessels may occur when the equilibrium is altered, thus forming an important pathological basis for VWF. This study was aimed at investigating vascular damage indicators as a basis for an early detection of disorders caused by vibration, using the rat tail model.

Experiments were conducted using a control group of rats not exposed to vibration while two exposed groups having different exposure durations of 7 and 14days were randomly formed. Following exposure, the structural changes of tail tissue samples in anesthetized rats were observed. Enzyme-linked immunosorbent assay (ELISA) was used for analyzing four vascular damage indicators myosin regulatory light chain (MLC2), endothelin-1 (ET-1), vinculin (VCL) and 5-hydroxytryptamine (5-HT) in tail blood samples. We found that both vascular smooth muscle and endothelial cells displayed changes in morphology characterized by vacuolization and swelling in the vibration-exposed group.
