EMA revealed that the MT group also showed more positive affective valence than the WC group across the 10 days. Notably, the WC group reported more negative affective valence following COVID-19 news exposure, whereas the MT group was not impacted. Taken together, our study indicates brief sessions of guided mindfulness meditation during COVID-19 may boost positive affect and serve as a protective buffer against the negative impact of exposure to COVID-19-related news on affective well-being. These findings highlight the utility of mindfulness meditation as an accessible and cost-effective technique to elevate positive affect amidst the COVID-19 pandemic.Strain SN6T is a non-motile and non-spore-forming gram-negative bacterium which was isolated from the stool sample of an Amazonian patient. The optimum growth was observed at 37 °C, pH 7, and 0-5 g/l of NaCl. Based on the 16S rRNA gene sequence similarity, the strain SN6T exhibited 97.5% identity with Vitreoscilla stercoraria strain ATCC_15218 (L06174), the phylogenetically closest species with standing in nomenclature. The predominant fatty acid was hexadecenoic acid (31%). The genomic DNA G + C content of the strain SN6T was 49.4 mol %. After analysis of taxonogenomic data, phenotypic and biochemical characteristics, we concluded that strain SN6T represents a new species of the genus Vitreoscilla for which the name Vitreoscilla massiliensis sp.nov is proposed. The type strain is SN6T (=CSUR P2036 = LN870312 = DSM 100958).Following recent Newcastle disease virus (NDV) outbreaks in Iranian poultry farms which were mostly associated with lesions of the avian gastrointestinal tract, it was speculated that the scale of the outbreaks could be attributed in part to co-circulating infectious agents or a new NDV genotype/subgenotype. This speculation was due to the isolation of a few 5th panzootic subgenotype VII.2 viruses from Iranian poultry farms in 2017. Samples from different species of commercial and domestic birds were collected from different provinces of Iran, 19 of which were selected for the current study. Phylogenetic analyses showed that the recent outbreaks have been caused by only one agent, i.e. the distinctive NDV subgenotype VII.1.1 (previously known VIIl) viruses that seem to be circulating predominantly in Iran, but have also been sporadically reported from Iraq among neighbouring countries. At most, 96.3-96.7% BLAST identity to non-Iranian VII.1.1 isolates was observed. Genetic distance values of  less then 1% were indicative of high similarity between the isolates, but the values were approaximately 2% when the current isolates were compared to the earliest recorded Iranian VII.1.1 viruses isolated in 2010. Using Bayesian analysis, annual mutation rates of 1.7156E-3 (strict) and 1.9902E-3 (relaxed) over 11 years were obtained. In addition, we report that our laboratories have not detected any genotype XIII strains since 2011. Following up on previous reports, we concluded that currently, and except in Columbiforms, subgenotype VII.1.1 may likely be the predominant subgenotype in many bird species in Iran despite the subgenotype VII.2 being predominant in neighbouring countries.CD47 is a widely expressed cell-surface protein that regulates phagocytosis mediated by cells of the innate immune system, such as macrophages and dendritic cells. CD47 serves as the ligand for a receptor on these innate immune cells, signal regulatory protein (SIRP)-α, which in turn inhibits phagocytosis. Several targeted CD47 therapeutic antibodies have been investigated clinically; however, how to improve its therapeutic efficacy remains unclear. Herein, we developed a CD47 blocking antibody, named IBI188, that could specifically block the CD47-SIRP-α axis, which transduces the "don't eat me" signal to macrophages. In vitro phagocytosis assays demonstrated the pro-phagocytosis ability of IBI188. Furthermore, several in vivo models were chosen to evaluate the anti-tumor efficacy of IBI188. IBI188 treatment upregulated cell movement- and inflammation-related genes in macrophages. CurcuminanalogC1 Synergism was observed when combined with an anti-CD20 therapeutic antibody, whose function depends on antibody-dependent cellular cytotoxicity/phagocytosis (ADCC/ADCP). CD47 expression was evaluated following azacytidine (AZA) treatment, a standard-of-care for patients with multiple myeloma; enhanced anti-tumor efficacy was observed in the combination group in AML xenograft models. Notably, IBI188 treatment increased vascular endothelial growth factor-A (VEGF-A) levels in a solid tumor model, and combined treatment with an anti-VEGF-A antibody and IBI188 resulted in an enhanced anti-tumor effect. These data indicate that IBI188 is a therapeutic anti-CD47 antibody with anti-tumor potency, which can be enhanced when used in combination with standard-of-care drugs for cancer treatment.

Tolerance to cannabinoids could limit their therapeutic potential. Male mice expressing a desensitization-resistant form (S426A/S430A) of the type-1 cannabinoid receptor (CB

R) show delayed tolerance to delta-9-tetrahydrocannabinol (∆

-THC) but not CP55,940. With more women than men using medical cannabis for pain relief, it is essential to understand sex differences in cannabinoid antinociception, hypothermia, and resultant tolerance.

Our objective was to determine whether female mice rely on the same molecular mechanisms for tolerance to the antinociceptive and/or hypothermic effects of cannabinoids that we have previously reported in males. We determined whether the S426A/S430A mutation differentially disrupts antinociceptive and/or hypothermic tolerance to CP55,940 and/or Δ

-THC in male and female S426A/S430A mutant and wild-type littermates.

The S426A/S430A mutation conferred an enhanced antinociceptive response for ∆

-THC and CP55,940 in both male and female mice. While the S426A/S430A mutatioessing the therapeutic potential and dependence liability of cannabinoids.To re-analyse the clinical outcomes and interferon (IFN) activity data from the JOQUER trial, a phase III trial investigating hydroxychloroquine (HCQ) in patients with primary Sjögren's syndrome (pSS), after stratifying patients into putative pathobiological subgroups utilizing the Newcastle Sjögren's Stratification Tool (NSST) based on patient-reported symptoms of dryness, pain, fatigue, anxiety and depression. 107 patients were assigned to one of four subgroups using NSST at baseline-the high symptom burden (HSB), pain dominant with fatigue (PDF), dryness dominant with fatigue (DDF) and low symptom burden (LSB). Endpoints were re-analysed after stratification, testing for treatment differences within subgroups and adjusting for baseline differences using a repeated measures covariate model. The HSB subgroup (n = 32) showed a relative improvement in ESSPRI of 1.49 points (95% CI 0.54-2.43; p = 0.002) within 12 weeks in patients taking HCQ compared to placebo, with no further changes after 24 weeks. For the LSB subgroup (n = 14), the ESSPRI worsened in the placebo but not the HCQ arm after 12 weeks (mean difference 1.
