There is an urgent need for vaccines and therapeutics to prevent and treat COVID-19. Rapid SARS-CoV-2 countermeasure development is contingent on the availability of robust, scalable, and readily deployable surrogate viral assays to screen antiviral humoral responses, define correlates of immune protection, and down-select candidate antivirals. Here, we generate a highly infectious recombinant vesicular stomatitis virus (VSV) bearing the SARS-CoV-2 spike glycoprotein S as its sole entry glycoprotein and show that this recombinant virus, rVSV-SARS-CoV-2 S, closely resembles SARS-CoV-2 in its entry-related properties. The neutralizing activities of a large panel of COVID-19 convalescent sera can be assessed in a high-throughput fluorescent reporter assay with rVSV-SARS-CoV-2 S, and neutralization of rVSV-SARS-CoV-2 S and authentic SARS-CoV-2 by spike-specific antibodies in these antisera is highly correlated. Our findings underscore the utility of rVSV-SARS-CoV-2 S for the development of spike-specific therapeutics and for mechanistic studies of viral entry and its inhibition.CD4+Foxp3+ regulatory T (Treg) cells are crucial for maintaining homeostasis and preventing autoimmune diseases. Nonetheless, we and others have previously reported that natural Treg cells are unstable and dysfunctional in the inflamed environment with a high-salt diet, limiting the Treg function in disease control. In this study, we made an innovative observation showing a high degree of heterogeneity within the Treg pool. We identified that CD126, interleukin (IL)-6 receptor alpha chain, contributed to Treg cell instability. Using a series of in vitro and in vivo experimental approaches, we demonstrated that CD126Lo/- Treg cells presented greater function and were more stable than CD126Hi nTreg cells, even in the presence of IL-6 and inflammation. Blockade of programmed death-1 (PD-1) interrupted CD126Lo/- nTreg cell stability. Additionally, CD126Lo/- Treg cells can treat colitis and established collagen-induced arthritis, while the CD126Hi cell population failed to do this. Moreover, we noted that CD126 expression of Treg cells had a positive correlation to rheumatoid arthritis (RA) severity and the stability of Treg cells. Our results strongly suggest that the manipulation of CD126Lo/- nTreg cells could be a novel strategy for the treatment of autoimmune diseases and for other conditions associated with a deficit of Treg cells.The increasing role of copper oxide nanoparticles (CuO NPs) in many industries and their broad range of applications increase its potential toxic effects. Curcumin possesses a wide range of health benefits. This study aimed to evaluate the role of curcumin in attenuating CuO NPs toxicity in rat kidney. Thirty six animals were divided into five groups; control groups (I, II), curcumin group orally received curcumin 200 mg/kg bw, CuO NPs group orally gavaged 250 mg/kg bw CuO NPs and combined group orally gavaged curcumin and CuO NPs. Treatment was given for 3 months. Administration of CuO NPs revealed elevation in serum creatinine and blood urea nitrogen levels, elevated kidney and urine levels of kidney injury molecule-1, decreased catalase, superoxide dismutase activities, total sulfhydryl, reduced glutathione content, increased serum reactive oxygen species, tissue total oxidant status, lipid hydroperoxides, protein carbonyl, malondialdehyde, nitric oxide levels, increased interleukin-1β, tumor necrosis factor-α, nuclear factor (NF-κB), and decreased heme oxygenase-1 (HO-1) and γ-glutamylcysteine synthetase (γ-GCS) genes expression. Moreover, histopathological alteration in kidney structure was detected. Immunohistochemical-stained sections by caspase-3 reaction revealed apoptosis. Pretreatment with curcumin improved most of the adverse effects in rats treated with CuO NPs regarding oxidative stress and inflammatory indices in kidney, and kept histopathological- and immunohistochemical-stained sections near to normal. This study shows that curcumin administration attenuates the toxicity in the kidney of CuO NPs-treated rats through its antioxidant, anti-inflammatory, and antiapoptotic effects.Pulmonary hypertension (PH) is a heterogeneous group of diseases defined by a mean pulmonary arterial pressure greater than 20 mmHg. Clinically, PH is classified into five groups and the group of PH generally defines the cause of PH and the therapeutic options. Etrumadenant Currently, medical therapies that target the prostacyclin, endothelin, and nitric oxide pathways are used in pulmonary arterial hypertension and chronic thromboembolic PH (CTEPH) patients. Moreover, surgery can improve outcomes in PH as pulmonary thromboendarterectomy can be curative for CTEPH and lung transplantation is used for end-stage PH. Despite these diverse treatment options, PH patients continue to have high symptom burden and poor long-term outcomes. However, advances in percutaneous technology are opening new avenues for the management of PH. In this review, we discuss the available data supporting the use of four interventional procedures balloon atrial septostomy, transcatheter Potts shunt, balloon pulmonary angioplasty, and pulmonary artery denervation for the treatment of PH. These procedures provide hemodynamic and functional improvements in PH patients, but they come with their own unique risk profiles. Hopefully, these procedures will continue to be refined and thereby provide a venue for interventional cardiology to safely and effectively improve outcomes for PH moving forward.Eliminating industrially produced trans-fatty acids (TFAs) from the food supply is one of the World Health Organization's (WHO's) priority targets to control and prevent non-communicable diseases. This review paper describes the strategies used to reduce TFA consumption in Thailand based on a situation analysis consisting of an assessment of TFA content in the national food supply, its intake, and stakeholder-based analysis of Strengths, Weaknesses, Opportunities, and Threats (SWOT). The analysis resulted in the drafting of a regulatory approach, which was then considered by stakeholders. link2 Bakery products containing partially hydrogenated oils (PHOs) are the major sources of TFAs in Thailand. Palm and coconut oil as well as blending technology are locally available as PHO replacements. Thailand's Food and Drug Administration has taken legal action to prohibit the production, import, and distribution of PHOs and their products. Post-marketing TFA levels are currently being monitored, ie, TFAs in fat/oil and butter must not exceed 2% and 6% of fat content, respectively. For other food categories, TFAs must not exceed 0.5 g per serving unless the TFAs are from ruminant sources. The key factor to successfully reducing TFAs in Thailand is the partnership between public and private sectors, professional associations, and consumers, based on scientific evidence regarding the negative impact of TFA intake on cardiovascular health.The hydrogenation of furfural (FUR), a typical bio-based furan derivative, is a critical reaction within the roadmap for upgrading lignocellulosic biomass into high value-added chemicals and liquid fuels, the performance of which is strongly correlated with the catalysts' intrinsic peculiarities. Metal catalysts with tailorable sizes, uniform dispersions and robust sintering resistance are generally recognized as a prerequisite for obtaining better hydrogenation activity, selectivity and stability, which has prompted intensive research into metal particle size effects and their regulation strategies. The roles of metal particle sizes and corresponding dispersions of metal catalysts used for FUR hydrogenation have been clearly recognized to be crucial over the past decade. In this regard, this systematic Minireview aims to provide profound insights into particle size effects in the metal-catalyzed hydrogenation of FUR, as well as conditional and structural approaches to regulating these effects. In addition, from the aspect of catalyst stability, the impacts and improvements of the metal particle sintering issue are analyzed. Moreover, several suggestions are proposed in response to the challenges in regulating particle size effects. Furthermore, the viewpoints presented herein would potentially contribute to the rational development of metal hydrogenation catalysts and further help to boost a more sustainable biomass refining system.The emphasis of our study was to determine the physiological function of miR-1224-5p in rectal cancer (RC) and its in-depth mechanism. First, the expression of miR-1224-5p in RC tissues was analyzed using public data from the TCGA database. Then, miR-1224-5p expression in RC cell lines SW480 and SW837 was measured using the qRT-PCR assay. The subsequent CCK-8 assay was executed to assess the function of miR-1224-5p in the viability of the RC cell. Bioinformatics prediction prompted that SLC29A3 may be a potential target gene for miR-1224-5p. Western blotting and dual-luciferase reporter assays were performed to affirm the above forecasting. Kaplan-Meier analysis and Cox multivariate analysis were carried out to assess the relationship between SLC29A3 and prognosis. Finally, CCK-8, colony formation assay, and transwell assay were used for functional analysis of miR-1224-5p/ SLC29A3 axis in vitro. MiR-1224-5p was expressed at low levels in RC tissues and cell lines. link3 Up-regulation of miR-1224-5p inhibited SW480 cell viability, while inhibition of miR-1224-5p enhanced the viability of SW837 cells. What is more, we affirmed that miR-1224-5p could direct target SLC29A3, which was expressed at high levels in RC tissues. In addition, SLC29A3 could be used as an independent predictive factor of prognosis in patients with RC, and the higher SLC29A3 expression, the lower survival rate. Finally, cellular functional experiments evidenced that miR-1224-5p mimic can reduce the cell viability, invasion, and migration, while overexpression of SLC29A3 presented an opposite effect. Importantly, co-transfection experiments indicated that SLC29A3 can reverse miR-1224-5p-mediated inhibition in the malignant progression of RC cells. Our work raised the possibility that miR-1224-5p functioned as a tumor suppressor in RC, which achieved its function via targeting SLC29A3.

Interpersonal problems are one of the most persistent difficulties facing those with personality disorders (PDs) and are linked with dysfunction across numerous social domains. Using an interpersonal model of PDs, we examined the indirect effects of Avoidant PD (AvPD) symptoms and social dysfunction through interpersonal problems, as well as Borderline PD (BPD) symptoms and social dysfunction.

Participants were 226 adults taking part in an outpatient treatment program.

Using cross-sectional data from self-reported measures, we found that cold (b = 0.10, 95% confidence interval (CI) [0.038, 0.176]) and overly nurturant (b = 0.04, 95% CI [0.001, 0.090]) interpersonal problems showed an indirect association between AvPD symptoms and social dysfunction. The only significant indirect association between BPD symptoms and social dysfunction was overly nurturant (b = 0.05, 95% CI [0.001, 0.120]).

Results may aid in the development of more individualized treatments for AvPD and BPD symptoms.
