The 2020 global outbreak of the novel coronavirus (SARS-CoV-2 or COVID-19) is a serious threat to international health, and thus, there is an urgent need for discovery of novel therapies or use of repurposed drugs that can make a significant impact on slowing the spread of the virus. Type 1 interferons (IFN-I) are a family cytokines of the early innate immune response to viruses that are being tested against SARS-CoV-2. However, coronaviruses similar to SARS-CoV-2 can suppress host IFN-I antiviral responses. Retinoids are a family molecules related to vitamin A that possess robust immune-modulating properties, including the ability to increase and potentiate the actions of IFN-I. Therefore, adjuvants such as retinoids, capable of increasing IFN-I-mediated antiviral responses, should be tested in combinations of IFN-I and antiviral drugs in pre-clinical studies of SARS-CoV-2.Traumatic brain injury (TBI) is one of the most significant health care problems worldwide, causing disability and death especially among young individuals. Although a large range of agents and therapies have been proved beneficial to lesions post-TBI to some extent, effective treatments have not been translated to the clinic. As a newly discovered form of iron-dependent regulated cell death, ferroptosis has been implicated in TBI. In this review, we update the current state of knowledge related to second injuries post-TBI, including ferroptosis, oxidative stress, mitochondrial dysfunction, neuroinflammation and so on, which often lead to chronic symptoms and long-term disability. This review systematically summarizes the latest progress in the pathophysiological mechanisms of TBI, with a focus on providing references for proposing new multi-molecular targets for comprehensive therapeutic strategies based on ferroptosis-relevant mechanisms. In addition, biomarkers are essential diagnostic and prognostic tools in TBI. Several biomarkers associated with the outcome of TBI have been listed in this article, such as Pde10a, MDA, UCH-L1, S100A9, S100B, ALDOC, ACSL4, MBP and F2-Isoprostane. Therefore, the understating of ferroptosis-relevant mechanisms and biomarkers may contribute to development of promising therapies for TBI clinical trials.Introduction Upper gastrointestinal bleeding (UGIB) is a leading cause of morbidity and associated with a 2-17% mortality in the United Kingdom (UK) and USA [1]. Peptic ulcers account for 50% of UGIB's. Endoscopic intervention in a timely manner can improve outcomes. Hemospray (Cook Medical, North Carolina, USA) is an endoscopic haemostatic powder for GI bleeding. This multicentre registry was created to collect data prospectively on the immediate Endoscopic haemostasis of GI bleeding in patients with peptic ulcer disease when Hemospray is applied as endoscopic monotherapy, dual therapy or rescue therapy. Methods Data were collected prospectively (January 2016 - March 2019) from 14 centres in the (UK, France, Germany and the USA). The application of Hemospray was decided upon at the endoscopist's discretion. Results 202 patients with UGIB secondary to peptic ulcers were recruited. Immediate haemostasis was achieved in 178/202 (88%) of patients, 26/154 (17%) had a re-bleed, 21/175 (12%) died within 7 days, 38/175 (22%) died within 30 days (all-cause mortality). Hemospray combination therapy with other endoscopic modalities had an associated lower 30-day mortality (16%, P less then 0.05) relative to Hemospray monotherapy or rescue therapy. There were high immediate haemostasis rates across all PUD Forrest classifications. Conclusions This is the largest case series of outcomes of peptic ulcer bleeds treated with Hemospray. There were high immediate haemostasis rates with Hemospray in oesophageal and peptic ulcer bleeds.Background and Aims Water filling during colonoscopy improves several colonoscopy outcomes. We evaluated an anecdotal observation that room temperature water filling during colonoscope insertion results in mucus production in the left colon, which may impair mucosal visualization during withdrawal. Methods We performed 55 colonoscopies with either water or saline filling during insertion, and video recorded the examinations. Three blinded observers scored the amount of mucus visible on the video recordings. Results Twenty-nine patients had water filling and 26 patients had saline filling during insertion. Demographic features, procedure indications, volume of infused fluid, and insertion time to the cecum were similar in both groups. All 3 blinded observers rated the mucus as greater after water filling compared to saline (median 3 out of 5 vs. 1 out of 5, p less then 0.001). Kappa value for interobserver agreement was 0.364 (p less then 0.001). Conclusion Room temperature water filling is associated with mucus production by the rectosigmoid colon, requiring additional cleansing during withdrawal.Background Endoscopic removal of foreign bodies, coagulated blood or necrotic debris is sometimes challenging and time consuming, also due to inadequate endoscopic instruments. selleck products Therefore, new devices are needed to overcome current limitations. Methods The OTSG is a new grasping tool that can be attached to any standard gastroscope. It has been developed for endoscopic removal of larger particles. We present retrospective data of five patients treated with the device for various indications (necrosectomy. bolus impaction, removal of blood clots). Results In two patients the OTSG was used for direct endoscopic necrosectomy after severe pancreatitis through a lumen-apposing metal stent. The other patients had a massive blood clot in the esophagus after endoscopic submucosal dissection, or aphagia due to large meat chunks clogging the esophagus, respectively. The OTSG has been used in all cases with technical success and without any procedure associated complications. Conclusion The OTSG appears to be a useful device for endoscopic removal of larger particles, blood clots or necrotic debris. Preliminary experience shows that the device is effective and easy to apply.The recently identified pathogenic Porcine circovirus type 3 (PCV3) may threaten to reduce the pig population dramatically worldwide. In our previous study, a PCV3-specific monoclonal antibody (mAb-1H11) was successfully applied in immune-histochemistry staining and ELISA, which specifically recognize PCV3 capsid protein in PCV3-positive pig tissues. In the present study, we expressed and purified the soluble sole capsid protein of PCV3. The purified capsid protein was capable of self-assembly into virus-like-particles (VLPs), which is validated by transmission electron microscopy and dynamic light scattering assays. Moreover, the epitope of mAb-1H11 was identified in the CD-loop region (a.a. 72-79) on the VLP surface, which is confirmed by PCV2-PCV3 epitope swapping assay. For the first time, we determined the cryo-EM structure of PCV3-VLP at 8.5 Å resolution that reveals the detailed structural information of PCV3-VLP. In our cryo-EM structure, PCV3-VLP is composed of 60 capsid protein subunits assembled with T = 1 icosahedral symmetry.
