Direct support professionals (DSPs) are instrumental to the daily operations of organizations that support people with intellectual and developmental disabilities (IDD). With extensive responsibilities, DSPs often experience high levels of stress and burnout that can result in turnover and vacant positions. Self-care is the practice of behaviors that promote well-being, counter work-related stress, and foster resilience. The current study explored self-care and resilience, and their relationship with professional quality of life (i.e., satisfaction, burnout, and secondary traumatic stress) among DSPs. Using a convenient sample, 153 DSPs (71% female) completed an online survey comprised of multiple measures. Results indicated that DSPs often engaged in self-care behaviors across physical, psychological, emotional, spiritual, relational, and workplace domains, however, less than 40% engaged in self-care behaviors directly related to work. On average, DSPs reported high levels of resilience. Collectively, self-care and resilience accounted for 12% to 28% of variance in DSPs' professional quality of life. Given the contribution of self-care to resilience and professional quality of life, an active approach by IDD organizations to foster self-care among DSPs may help promote their longevity and retention.In late December 2019, an ongoing outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that was termed Coronavirus Disease 2019 (COVID-19), was reported in Wuhan, China (Zhu, et al 2020).Aims To investigate the association of several single nucleotide polymorphisms (SNPs) within alpha-synuclein (SNCA) gene, and additional gene- environment interaction with Parkinson's disease (PD) risk. Methods Hardy-Weinberg equilibrium (HWE) is tested for controls using SNPstats (http//bioinfo.iconcologia.net/SNPstats). Logistic regression is used to calculate the ORs (95% CI) for relations between the four SNPs and PD risk. The generalized multifactor dimensionality reduction (GMDR) model is used to evaluate the synergy between gene and environment. Results A total of 1161 people were included in this study, including 386 cases of PD and 775 normal controls. In this study, the genotype frequency of the control group was consistent with HWE distribution. Rs356219-G allele frequency was 30.0% in patients and 19.8% in control group. The rs356221-T allele frequency was 29.7% in the patients and 20.8% in the control group. Rs356219-G and rs356221-T alleles were associated with increased PD risk, with adjusted ORs (95% CI) of 1.92 (1.28-2.52) and 1.52 (1.05-2.02), respectively. We also found no significant correlation between rs2301134 and rs2301135 and susceptibility to PD. The best gene-environment interaction models were determined by GMDR analysis, which shown a significant gene- T2DM interaction combinations, but the gene- alcohol drinking interaction combinations were all not significant. We also conducted stratified analysis for interaction effect using logistic regression. We found that T2DM patients with rs356221- AT/ TT genotype have the highest PD risk, compared to subjects with rs356219- AA genotype, OR (95%CI) =2.67 (1.83 -3.46). Conclusions The rs356219- G and rs356221- T, gene- environment interaction between rs356221 and T2DM were all associated with increased PD risk.About 60-85% of total phosphorus (P) in cereal crops is finally allocated to the seeds, which is required for seed development, germination, and early growth. However, little is known on the molecular mechanisms underlying P allocation to the seeds. Here, we found that two members (OsPHO1;1 and OsPHO1;2) belonging to PHO1 gene family, are involved in the distribution of P to the seeds in rice. Both OsPHO1;1 and OsPHO1;2 were localized to the plasma membrane and showed influx transport activities for inorganic phosphate. At the reproductive stage, both OsPHO1;1 and OsPHO1;2 showed higher expression in the node I, the uppermost node connecting to panicle. OsPHO1;1 was mainly localized at the phloem region of diffuse vascular bundles of node I, while OsPHO1;2 was expressed in the xylem parenchyma cells of the enlarged vascular bundles. In addition, they were also expressed in the ovular vascular trace, the outer layer of the inner integument (OsPHO1;1) and the nucellar epidermis (OsPHO1;2) of caryopsis. Knockout of OsPHO1;2 as well as OsPHO1;1 with less extent decreased the distribution of P to the seed, resulting in decreased seed size and delayed germination. Taken together, OsPHO1;2 expressed in node I is responsible for unloading of P from the xylem of enlarged vascular bundles, while OsPHO1;1 is involved in reloading P into phloem of diffuse vascular bundles for subsequent allocation of P to the seeds. Furthermore, OsPHO1;1 and OsPHO1;2 expressed in the caryopsis are important for delivering of P from the maternal tissues to the filial tissues for seed development.The relationships between impaired cortical development and consequent malformations in neurodevelopmental disorders, as well as the genes implicated in these processes, are not fully elucidated to date. In this study, we report six novel cases of patients affected by BBSOAS (Boonstra-Bosch-Schaff optic atrophy syndrome), a newly emerging rare neurodevelopmental disorder, caused by loss-of-function mutations of the transcriptional regulator NR2F1. Young patients with NR2F1 haploinsufficiency display mild to moderate intellectual disability and show reproducible polymicrogyria-like brain malformations in the parietal and occipital cortex. Using a recently established BBSOAS mouse model, we found that Nr2f1 regionally controls long-term self-renewal of neural progenitor cells via modulation of cell cycle genes and key cortical development master genes, such as Pax6. In the human fetal cortex, distinct NR2F1 expression levels encompass gyri and sulci and correlate with local degrees of neurogenic activity. In addition, reduced NR2F1 levels in cerebral organoids affect neurogenesis and PAX6 expression. We propose NR2F1 as an area-specific regulator of mouse and human brain morphology and a novel causative gene of abnormal gyrification.An understanding of the molecular mechanisms that underlie plant salt tolerance is important for both economic and scientific interests. Genome-wide Association Study (GWAS) is a promising approach to pinpoint genes that confer plant salt tolerance. With the advancement of supporting technology and methodology, GWAS has enabled the discovery of genes that play central roles in regulating plant salt tolerance in the past decade. Here I highlight recent successful GWAS work in unveiling the molecular factors underlying plant salt tolerance, and discuss the concerns and opportunities in conducting such experiments. It is anticipated that GWAS will be increasingly successful in the identification of key genes that are useful for crop improvement.Patients with coronavirus disease 2019 (COVID-19) have elevated D-dimer levels. Early reports describe high venous thromboembolism (VTE) and disseminated intravascular coagulation (DIC) rates, but data are limited. This multicenter, retrospective study described the rate and severity of hemostatic and thrombotic complications of 400 hospital-admitted COVID-19 patients (144 critically ill) primarily receiving standard-dose prophylactic anticoagulation. Coagulation and inflammatory parameters were compared between patients with and without coagulation-associated complications. Multivariable logistic models examined the utility of these markers in predicting coagulation-associated complications, critical illness, and death. The radiographically-confirmed VTE rate was 4.8% (95% CI, 2.9-7.3%) and the overall thrombotic complication rate was 9.5% (6.8-12.8%). The overall and major bleeding rates were 4.8% (2.9-7.3%) and 2.3% (1.0-4.2%). In the critically ill, radiographically-confirmed VTE and major bleeding rates 9 patients.Nowadays, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which caused novel coronavirus disease (COVID-19) pandemic, is the worldwide challenge. The virus is highly contagious, and clinical consequences were very divers. It is estimated that if no effective action is taken, COVID-19 could plague 90% of the world's population and kill over 40 million people. So, it is essential to understand the virus pathogenicity and follow the preventive methods to control the high morbidity and mortality rates. Meanwhile our current knowledge of COVID-19 is still limited, despite hard efforts of scientists and clinicians during last few months. In this review article, we have collected the latest data about characteristics, pathogenesis, clinical manifestations, and diagnostic methods of SARS-CoV-2. This article is protected by copyright.

The world-wide response to the COVID-19 pandemic has been unprecedented with government, academic, and private partnerships working together to rapidly develop vaccine and antibody countermeasures. Many of the technologies being used are derived from prior government-academic partnerships for response to other emerging infections.Early detection and effective treatment of severe COVID-19 patients remain major challenges. Here, we performed proteomic and metabolomic profiling of sera from 46 COVID-19 and 53 control individuals. We then trained a machine learning model using proteomic and metabolomic measurements from a training cohort of 18 non-severe and 13 severe patients. The model was validated using 10 independent patients, 7 of which were correctly classified. Targeted proteomics and metabolomics assays were employed to further validate this molecular classifier in a second test cohort of 19 COVID-19 patients, leading to 16 correct assignments. We identified molecular changes in the sera of COVID-19 patients compared to other groups implicating dysregulation of macrophage, platelet degranulation, complement system pathways, and massive metabolic suppression. This study revealed characteristic protein and metabolite changes in the sera of severe COVID-19 patients, which might be used in selection of potential blood biomarkers for severity evaluation.The spike glycoprotein on the virion surface docking onto the angiotensin-converting enzyme (ACE) 2 dimer is an essential step in the process of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in human cells-involves downregulation of ACE2 expression with systemic renin-angiotensin system (RAS) imbalance and promotion of multi-organ damage. In general, the RAS induces vasoconstriction, hypertension, inflammation, fibrosis, and proliferation via the ACE/Ang II/Ang II type 1 receptor (AT1R) axis and induces the opposite effects via the ACE2/Ang (1-7)/Mas axis. The RAS may be activated by chronic inflammation in hypertension, diabetes, obesity, and cancer. Ponatinib research buy SARS-CoV-2 induces the ACE2 internalization and shedding, leading to the inactivation of the ACE2/Ang (1-7)/Mas axis. Therefore, we hypothesize that two hits to the RAS drives COVID-19 progression. In brief, the first hit originates from chronic inflammation activating the ACE/Ang II/AT1R axis, and the second originates from the COVID-19 infection inactivating the ACE2/Ang (1-7)/Mas axis.
