In severe cases of coronavirus disease 2019 (COVID-19), viral pneumonia progresses to respiratory failure. Neutrophil extracellular traps (NETs) are extracellular webs of chromatin, microbicidal proteins, and oxidant enzymes that are released by neutrophils to contain infections. However, when not properly regulated, NETs have potential to propagate inflammation and microvascular thrombosis - including in the lungs of patients with acute respiratory distress syndrome. While elevated levels of blood neutrophils predict worse outcomes in COVID-19, the role of NETs has not been investigated. We now report that sera from patients with COVID-19 (n = 50 patients, n = 84 samples) have elevated levels of cell-free DNA, myeloperoxidase(MPO)-DNA, and citrullinated histone H3 (Cit-H3); the latter two are highly specific markers of NETs. Highlighting the potential clinical relevance of these findings, cell-free DNA strongly correlated with acute phase reactants including C-reactive protein, D-dimer, and lactate dehydrogenase, as well as absolute neutrophil count. MPO-DNA associated with both cell-free DNA and absolute neutrophil count, while Cit-H3 correlated with platelet levels. Importantly, both cell-free DNA and MPO-DNA were higher in hospitalized patients receiving mechanical ventilation as compared with hospitalized patients breathing room air. Finally, sera from individuals with COVID-19 triggered NET release from control neutrophils in vitro. In summary, these data reveal high levels of NETs in many patients with COVID-19, where they may contribute to cytokine release and respiratory failure. Future studies should investigate the predictive power of circulating NETs in longitudinal cohorts, and determine the extent to which NETs may be novel therapeutic targets in severe COVID-19.Objective. Microelectronic retinal prostheses are a promising solution for sight restoration in cases of blindness caused by outer retinal degenerative diseases. Despite immense technological advances, the best visual acuity restored by microelectronic prostheses remains limited, implying poor understanding of the physiological underpinnings of retinal implants.Approach. In this perspective, we discuss the neurophysiological and medical issues that must be considered to substantially improve prosthetic performance.Main results. The eventual goal for retinal prostheses is to faithfully replicate neural signaling patterns arising in retinal ganglion cells (RGCs) during natural viewing. Two major challenges for microelectronic prostheses are 1) to reproduce intrinsically heterogeneous population codes of RGCs that originate from the remarkable diversity of retinal neurons and 2) to selectively activate specific RGC types to mimic the exclusive firing of ON and OFF channels. These fundamental challenges should be addressed to obtain high-quality artificial vision. To further develop prosthetic devices that are successful for long-term use, we discuss animal models for developing new surgical techniques and device testing. As an economic/ethical alternative to genetic modification, animal models of drug-induced outer retinal degeneration are discussed.Significance. Combined, the presenting perspective highlights the crucial issues for more successful retinal implants.

Kaplan-Meier survival curves showed that overall survival (OS) and disease-free survival (DFS) rates were significantly associated with two ATM SNPs, rs664143 and rs189037. Patients with the rs664143 GA or AA genotype had poorer DFS (hazard ratio (HR) = 1.40, 95% confidence interval (CI) = 1.05-1.86, P = 0.021) and OS (HR = 1.28, 95%CI = 1.12-1.78, P = 0.040) than those with the rs664143 GG phenotype. Patients with the rs189037 AG/GG genotypes had poorer prognoses than those with the rs189037 AA genotype (AG/GG vs. AA DFS, HR = 1.44, 95%CI = 1.06-1.95, P=0.019; OS, HR = 1.16, 95%CI = 1.16-1.17-2.21, P=0.004). These results were confirmed by subgroup analysis based on clinical factors such as smoking, histology, tumor stage, treatment, and radiation dose, all of which were significantly associated with DFS and OS rates in NSCLC patients. These findings show that ATM rs664143 and rs189037 variants determine prognosis in NSCLC patients that have undergone radiation or chemoradiation therapies.Background Albizia zygia (DC.) J.F. Macbr. (Leguminosae) has been used to treat mental disorders in traditional African medicine. Nonetheless, there is limited scientific evidence to justify its present use. The aim of this study was to evaluate the antidepressant activity of the hydroethanolic extract of A. zygia roots (AZE) in murine models. Methods AZE was evaluated in the tail suspension test, forced swim test, and the repeated open-space swim test of depression. In order to elucidate the mechanisms of action, the activity of AZE was re-evaluated after treating mice with selective inhibitors of monoamine biosynthesis. MNU chemical in vitro The potential of AZE to influence spontaneous locomotion was also examined. Results AZE (100-1000 mg/kg, p.o.) reduced the immobility time of mice in the tail suspension and forced swim tests (at least p less then 0.05). In the repeated open-space swim test, AZE reduced the immobility time (at least p less then 0.05) while concomitantly increasing the distance swam by mice (p less then 0.01). However, the antidepressant-like activity of AZE was attenuated by α-methyl-para-tyrosine and reserpine (p less then 0.0001) but not para-chlorophenylalanine. Conclusions The results of this study indicate that AZE possesses antidepressant-like properties and support the traditional use of AZE for the treatment of depression.To date, a large number of synthetic drugs have been developed for the treatment and prevention of different disorders, such as neurodegenerative diseases, diabetes mellitus, and cancer. However, these drugs suffer from a variety of drawbacks including side effects and low efficacy. In response to this problem, researchers have focused on the plant-derived natural products due to their valuable biological activities and low side effects. Flavonoids consist of a wide range of naturally occurring compounds exclusively found in fruits and vegetables and demonstrate a number of pharmacological and therapeutic effects. Tangeretin (TGN) is a key member of flavonoids that is extensively found in citrus peels. It has different favorable biological activities such as antioxidant, anti-inflammatory, antitumor, hepatoprotective, and neuroprotective effects. In the present review, we discuss the various pharmacological and therapeutic effects of TGN and then, demonstrate how this naturally occurring compound affects signaling pathways to exert its impacts.The standard nature of the procedures and tools of sampling and data collection cannot guarantee the stability of data reliability and validity because non-sampling errors are highly sensitive to social conditions. The present study provides a post-hoc attempt to estimate and manage the changing methodological parameters of self-report surveys of addictive behaviours (being highly subjected to changes in social conditions) to make data interpretation easier. The analysis is based on the data of two national Hungarian representative surveys assessing addiction problems in 2007 and 2015 (National Survey on Addiction Problems in Hungary [NSAPH]). Both surveys were conducted using a Hungarian nationwide representative sample aged 18-64 years applying similar procedures in data collection and -processing. Regarding data concerning substance use, both surveys included variables to estimate non-sampling errors in line with current international practices. The methodological parameters of NSAPH2015 showed an increase in non-sampling errors regarding substance use behaviour compared to NSAPH2007. The present paper elaborates an estimation procedure based on the assumption that when following a population, the proportion of people who have ever engaged in a specific type of addictive behaviour cannot be reduced in the given population over time. This also applies to cohorts followed by cross-sectional surveys among national representative samples, as far as lifetime prevalence and data on the age of first use/activity is available. To identify valid trends in different behaviours in epidemiological research assessing addictive behaviours or other sensitive data, researchers should provide the required conditions for controlling or correcting data by cohort analysis.BACKGROUND A couple of studies suggest that sunshine duration and ambient temperature contribute to suicide. Few studies have happened in East-Central European area. OBJECTIVE We scrutinized the daily suicide rates and other measured meteorological parameters spanning from 1971 to 2013 in the region of Hungary exhibiting the highest suicide rate. METHODS The meteorological parameters measured in the area signified the independent variables of the statistical model, while the observed suicide rate connoted the dependent variable. link2 Dynamic Regression, a time series analytical method was employed for creating the model. RESULTS Three meteorological parameters displayed a weak, yet statistically significant relationship with suicide rates. 1/ Daily sunshine duration has shown an immediate, significant positive correlation, 2/ daily changes in temperature at ground level also exhibited a significant relationship, albeit it followed a complex transient profile overarching three days. Tropopause height was also significant in the model an immediate positive effect was followed by a negative effect six days later. CONCLUSIONS We estimated consistent and immediate positive associations between daily suicide and daily change of elevated ambient temperature and duration of sunshine in a high rated area of Hungary.BACKGROUND Depression is a common mental health disorder which has become a global public health issue. It constitutes around 35 to 45% of mental health problems in Iran and covers 8% to 20% of population of Iran. Therefore, the present study aimed to determine the prevalence of depression among the Iranian patients through systematic review and meta-analysis. link3 METHOD For the present study information were searched in Web of Science, Scopus, PubMed, Google Scholar, and in Iranian databases including Iran Medex, SID, MedLib, Scientific Information Database, MagIran, using the following keywords "depression", "prevalence" and Iran. The data from these databases were analyzed through meta-analysis (random effects model). Heterogeneity among the results of the studies was examined by I2 index. Beck Depression Inventory (BDI), Depression Anxiety and Stress Scale-21 (DASS-21), General Health Questionnaire-28 (GHQ-28), and Geriatric Depression Scale (GDS) were used in this study, and statistical analyses were performed using STATA Ver.16. RESULTS A total of 46 studies conducted in Iran based on a sample size of 2960 individuals was found during the time period of 2010 and 2018. Prevalence of depression among Iranian patients was estimated to be 34.26 (95% CI, 24.12% - 44.10%). Thus, the findings indicated that there exists a moderate prevalence of depression which is continuously growing. CONCLUSION The prevalence of depression in Iran is moderate and growing which is alarming as it may turn out to be a massive increase in incidence rate of depression in coming years. This indicates a greater risk for Iranian population and calls for effective measures to be taken to control the mental health problems among Iranian patients.
