IFN-αω is an emergent subtype of type I IFNs which has been primarily characterized in domestic pigs. In this study, the PoIFN-αω cDNA was cloned from Chinese Bama miniature pigs by RT-PCR, and its tissue expression profile was analyzed by real-time RT-PCR. The cDNA was expressed in Escherichia coli as a His-tagged protein and purified by nickel affinity chromatography. The antiviral activities of recombinant PoIFN-αω (rPoIFN-αω) against four different pig viruses were measured using cytopathic effect (CPE) inhibition assay. Although the PoIFN-αω sequence of Bama miniature pigs was identical to that of domestic pigs, the tissue expression profiles differed significantly between the two pig species. The rPoIFN-αω showed dose-dependent pre-infection antiviral activities against porcine pseudorabies virus, vesicular stomatitis virus and porcine reproductive and respiratory syndrome virus, but not against porcine circovirus type 2. When used as treatment post infection with the three viruses, rPoIFN-αω showed the efficacy in decreasing CPE in the infected cells in a time-dependent manner. Therefore, the expressed rPoIFN-αω could be used as an antiviral agent against pig virus infections.Ischemic stroke is one of the leading causes of death and disability worldwide. Although miR-149-5p downregulation is observed in rats after ischemia/reperfusion (I/R) injury, its function and role in ischemic stroke remain unclear. This study aimed to investigate the roles of miR-149-5p in I/R injury. The results showed that miR-149-5p was significantly downregulated in brain tissues of rats subjected to middle cerebral artery occlusion (MCAO) and primary cortical neurons subject to oxygen and glucose deprivation (OGD). MiR-149-5p overexpression effectively reduced MCAO/R-induced infarct volume, neurological score, and brain water content as well as OGD/R-induced cortical neurons apoptosis and OGD/R-induced expression of TNF-α, IL-4, IL-6, IL-1β, and COX-2. Moreover, Notch2 was identified as a target of miR-149-5p and Notch2 overexpression significantly attenuated the inhibitory effects of miR-149-5p mimics on inflammation and apoptosis. Taken together, our study revealed that miR-149-5p overexpression protects the rat brain against I/R injury by regulating Notch2-mediated inflammation and apoptosis pathway.

Racial disparities in colorectal surgery outcomes have been studied extensively in the USA, and access to healthcare resources may contribute to these differences. The Veterans Health Administration (VHA) is the largest integrated healthcare network in the USA with the potential for equal access care to veterans. The objective of this study is to evaluate the VHA for the presence of racial disparities in 30-day outcomes of patients that underwent colorectal resection.

Colon and rectal resections from 2008 to 2019 were reviewed retrospectively using the Veterans Affairs Surgical Quality Improvement Program database. Patients were categorized by race and ethnicity. Multivariable analysis was used to compare 30-day outcomes. Cases with "unknown/other/declined to answer" race/ethnicity were excluded.

Thirty-six-thousand-nine-hundred-sixty-nine cases met inclusion criteria 27,907 (75.5%) Caucasian, 6718 (18.2%) African American, 2047 (5.5%) Hispanic, and 290 (0.8%) Native American patients. There were no stae racial disparities in clinical outcomes still persisted in this analysis. Further efforts beyond healthcare access are needed to mitigate disparities in colorectal surgery.

The global spread of COVID-19 has brought immense psychological distress and sleep problems to those affected. This study examined the mediating role of rumination in the direct association between COVID-19 stressors and poor sleep quality and the moderating roles of emotion regulation strategies.

A cross-sectional online survey study was conducted in China during the early outbreak of the pandemic. A total of 1106 Chinese college students (M

 = 19.58, SD = 1.61) completed measures of COVID-19 stressors, rumination, emotion regulation strategies (i.e., cognitive reappraisal and expressive suppression), and poor sleep quality.

COVID-19 stressors were positively associated with poor sleep quality (β = .431, p < .001), and rumination partially mediated this association. The mediation effect accounted for 70.93% of the total effect of COVID-19 stressors on poor sleep quality. Moreover, cognitive reappraisal moderated the relation between COVID-19 stressors and rumination, and expressive suppression moderated the association between rumination and poor sleep quality.

Rumination could be a mechanism by which COVID-19 stressors are linked with poor sleep quality. Cognitive reappraisal might provide desired benefits to improving sleep quality while expressive suppression may do the opposite. Implications for future steps and health interventions are discussed.

The study aims to evaluate the immunomodulatory gene expression on HT-29 cell line using Bacillus licheniformis MCC 2514 and Bifidobacterium breve NCIM 5671 as a single culture and in combination. Upon inflammation induced by LPS, the combination of bacteria downregulated the pro-inflammatory cytokines IL-1α (13.4), IL-12 (14.6), IL-8 (2.6), and IL-6 (1.9), and in contrast, TNF-α (21.2) folds has upregulated. However, anti-inflammatory genes such as IL-4 (0.6), IL-10 (2.9), TGF-2 (92.2), and TGF-3 (85.8) folds were upregulated. The combination of bacteria against oxidative stress downregulated the pro-inflammatory cytokines such as IL-1α & β, IL-6, IL-8, IL-12, and IL-18, and upregulated the anti-inflammatory cytokines IL-10, IL-4, TGF-2, and TGF-3. On the introduction of Kocuria rhizophila, the pro-inflammatory cytokines were upregulated. On supplementation of B. licheniformis and B. breve, the upregulated pro-inflammatory cytokines were decreased, and anti-inflammatory cytokines such as IL-4 (6.2), IL-10 (23.5), TGF-2 (166), and TGF-3(28.4) folds were increased. However, gene expression of toll-like receptor-2 was found high (26 folds) upon introducing probiotic bacteria. ELISA results of Interferon-γ found that the expression was higher (7.19 ng/mL) on the introduction of both the bacteria in combination. The higher anti-inflammatory activity was observed when potential probiotic bacteria were used in combination compared to a single culture. Overall study indicates that the combination of aerobic B. licheniformis and anaerobic B. breve has an anti-inflammatory activity that can sustain an excellent gastrointestinal environment during pathogen invasion and inflammation.IEGs play a critical functional role of in molecular, cellular, and behavioral alterations induced by psychostimulants. IEGs appear to have specific chromatin structures that may contribute to the rapid activation of their transcription. HDAC enzymes regulate reversible acetylation of lysine residues of histones and non-histone proteins. Dysregulation of HDACs has been proposed to modulate the establishment and maintenance of aberrant transcriptional programs and behaviors associated with cognitive dysfunctions and drug addiction. In this mini-review we focus our attention on recent discoveries concerning networks of protein-protein interactions for the two classes of HDAC protein family members that are highly expressed in neurons, class I and IIa HDACs. Because dynamic histone acetylation appears to be critical to IEG expression in the brain, we discuss the role of these epigenetic regulators on IEG expression induced by cocaine and methamphetamine intake.

Polyvinylpyrrolidone-iodine (PVP-I) demonstrates broad-spectrum anti-infective activity and is available in different formulations for oral rinse and topical use in medical and personal care settings. The novel severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) has underscored the need to supplement available preventive strategies.

We assessed virucidal activity of PVP-I formulations, including 0.5% (w/v) solution, 5.0% (w/v) solution, 7.5% (w/v) scrub, and 10.0% (w/v) solution, versus placebos when challenged with coronaviruses in two in vitro studies. Murine coronavirus strain A59 (American Type Culture Collection [ATCC]

VR-764™), human coronavirus strain OC43 (ZeptoMetrix Corp. #0810024CF), human coronavirus strain NL63 (ZeptoMetrix Corp. #0810228CF), and human coronavirus strain 229E (ATCC

VR-740™) were used as surrogates for SARS-CoV-2. Both studies used the American Society for Testing and Materials in vitro time-kill method.

All active PVP-I formulations in study1 demonstrated virucidal activity at 15s, with mean log

reduction of greater than 4.56 or greater than 99.99% inactivation; a cytotoxic effect against the National Collection of Type Cultures clone 1469 host cells was observed with 5.0% (w/v) solution, 7.5% (w/v) scrub, and 10.0% (w/v) solution. Active PVP-I formulations in study2 demonstrated effective virucidal activity against coronaviruses in less than 15s; log

reduction in viral titer for each coronavirus strain was consistently higher for 10.0% (w/v) solution and 0.5% (w/v) solution versus 7.5% (w/v) scrub.

Both studies demonstrated in vitro virucidal activity of PVP-I formulations when challenged with SARS-CoV-2 surrogate coronaviruses. Although promising, further investigations are needed to evaluate SARS-CoV-2 inactivation.

A cross-sectional study was conducted to assess HPV infection and associated risks knowledge level among learners attending high schools in the Eastern Cape Province of South Africa. Learners (females and males) attending five selected schools in the Eastern Cape Province of South Africa participated. The intervention included knowledge pre-assessment, education through structured lecture, and post-education assessment. Self-administered questionnaires were used in both pre and post-intervention assessments. There were 2652 learners, who participated, with a median age of 18 years (IQR 16-19). Female participants constituted 53.58% (1421/2652), and male participants were 46.42% (1231/2652). Before education intervention, only 4.08% (107/2623) of learners ever heard about HPV and 3.31% (87/2626) about HPV vaccination. Only 9.36% (247/2638) and 9.
