e. MMV1 (HK, 284.1 Da) and MMV2 (GQCC, 410.1 Da). The data suggested that the MMV2 peptide have maximum activity and was found to be stable at high temperatures. The MMV2 peptide demonstrated abrupt localization throughout the adult zebrafish body and successfully downregulated the mRNA levels of inflammation-related genes in LPS-induced adult zebrafish. This study indicates that the peptide MMV2 possesses anti-inflammatory activity by suppressing the induced inflammation and can be a strong competitor against non-steroidal anti-inflammatory drugs (NSAIDs).RNA virus infection activates the RIG-I-like Receptor (RLR) signaling pathway to produce type I interferons (IFNs), the key components of the antiviral immune response. Forkhead box O1 (FoxO1) is a host transcription factor that participates in multiple biological processes. In this study, FoxO1 was identified as a critical negative regulator of RIG-I-triggered signaling. Molidustat FoxO1 promoted Sendai virus (SeV) replication and downregulated type I IFN production. Upon SeV infection, FoxO1 suppressed K63-linked ubiquitination of TRAF3 and the interaction between TRAF3 and TBK1, after which the production of type I IFNs via the interferon regulatory transcription factor 3 (IRF3) pathways was reduced. In addition, FoxO1 destabilized IRF3 by facilitating E3 ligase TRIM22- or TRIM21-mediated K48-linked ubiquitination of IRF3. Moreover, the inhibitory effect of FoxO1 was found to depend on its DNA binding domain (DBD). Thus, our findings highlight novel important roles of FoxO1 in controlling RLR-mediated antiviral innate immunity.Metastasis commonly occurs in colorectal cancer (CRC) patients and confers a poor prognosis. B7-H4, an immune checkpoint molecule, has been found to be expressed in numerous tumor tissues and play critical roles in tumor progression. However, B7-H4 expression and its prognostic significance in different metastases from CRC remain unclear. In the present study, we screened a novel mouse anti-human B7-H4 monoclonal antibody (mAb) which exhibited a higher degree of recognition and sensitivity than the commercial reagent in immunohistochemistry (IHC). Using this antibody, overall 110 metastatic and paired primary lesions of CRC were analyzed for their expression of B7-H4, CD8 and CD68. Our results showed that expression of B7-H4 and CD68 in metastastic lesions was significantly higher than that in matched primary lesions (P = 0.0016, P less then 0.0001). We also found a significant increase of CD68-positive immune cell infiltration in the B7-H4 high expressing metastases (P = 0.041). Moreover, upregulated B7-H4 in metastatic lesions was correlated with poor prognosis of patients (P = 0.014), while in primary lesions, B7-H4 combined with CD8 was associated with the overall survival (OS) (P = 0.043). Further, B7-H4 expression in metastatic lesions was significantly correlated with hazard ratio (HR) both in univariate and multivariate analysis. Altogether, B7-H4 in metastatic lesions is promising to be a potential prognostic indicator of CRC, and may promote tumor progression and metastasis of this cancer.

The purpose of this study was to identify in the EPIRMEX cohort the correlations between MRI brain metrics, including diffuse excessive high signal intensities (DEHSI) obtained with an automated quantitative method and neurodevelopmental outcomes at 2 years.

A total of 390 very preterm infants (gestational age at birth≤32 weeks) who underwent brain MRI at term equivalent age at 1.5T (n=338) or 3T (n=52) were prospectively included. Using a validated algorithm, automated metrics of the main brain surfaces (cortical and deep gray matter, white matter, cerebrospinal fluid) and DEHSI with three thresholds were obtained. Linear adjust regressions were performed to assess the correlation between brain metrics with the ages and stages questionnaire (ASQ) score at 2 years.

Basal ganglia and thalami, cortex and white matter surfaces positively and significantly correlated with the global ASQ score. For all ASQ sub-domains, basal ganglia and thalami surfaces significantly correlated with the scores. DEHSI was present in 289 premature newborns (74%) without any correlation with the ASQ score. Metrics of DEHSI were greater at 3T than at 1.5T.

Brain MRI metrics obtained in our multicentric cohort correlate with the neurodevelopmental outcome at 2 years of age. The quantitative detection of DEHSI is not predictive of adverse outcomes. Our automated algorithm might easily provide useful predictive information in daily practice.

During the coronavirus disease 2019 (COVID-19) pandemic, providers and patients must engage in shared decision making to ensure that the benefit of early intervention for muscle-invasive bladder cancer exceeds the risk of contracting COVID-19 in the clinical setting. It is unknown whether treatment delays for patients eligible for curative chemoradiation (CRT) compromise long-term outcomes.

We used the National Cancer Data Base to investigate whether there is an association between a≥ 90-day delay from transurethral resection of bladder tumor (TURBT) in initiating CRT and overall survival. We included patients with cT2-4N0M0 muscle-invasive bladder cancer from 2004 to 2015 who underwent TURBT and curative-intent concurrent CRT. Patients were grouped on the basis of timing of CRT≤ 89 days after TURBT (earlier) vs.≥ 90 and< 180 days after TURBT (delayed).

A total of 1387 (87.5%) received earlier CRT (median, 45 days after TURBT; interquartile range, 34-59 days), and 197 (12.5%) received delayed CRT (median, 111 days after TURBT; interquartile range, 98-130 days). Median overall survival was 29.0 months (95% CI, 26.0-32.0) versus 27.0 months (95% CI, 19.75-34.24) for earlier and delayed CRT (P= .94). On multivariable analysis, delayed CRT was not associated with an overall survival difference (hazard ratio, 1.05; 95% CI, 0.87-1.27; P= .60).

Although these results are limited and require validation, short, strategic treatment delays during a pandemic can be considered on the basis of clinician judgment.
