Over the last several months,a global pandemic has developed due to the emergence of the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which is capable of infecting *** lack of preexisting immunity to SARSCoV-2 in humans has prompted the scientific community to strive to understand the mechanisms underlying SARS-CoV-2 pathogenesis and to test new therapeutic agents and vaccines for the clinical management of coronavirus disease 2019(COVID-19).In these efforts,the development of appropriate animal models of the disease is one of the most valuable strategies.

Cancer stem cells(CSCs),also known as tumor initiating cells,are a minority subpopulation of undifferentiated cancerous cells within the entire tumor that hold self-renewal capacity and differentiation *** are critical for tumor progression,heterogeneity and metastasis and play a major role in chemo-and radiation-resistance and tumor recurrence[1].Although the molecular mechanisms underlying the ability of CSCs to give rise to new tumors and promote resistance to many cancer therapies are not completely understood,increasing knowledge suggests potential roles for these cells in the evasion of immune surveillance[2,3].

AIM: To address endoscopic outcomes of post-Orthotopic liver transplantation (OLT) patients diagnosed with a "redundant bile duct" (RBD). METHODS: Medical records of patients who underwent OLT at the Liver Transplant Center, University Texas Health Science Center at San Antonio Texas were retrospectively analyzed. Patients with suspected biliary tract complications (BTC) underwent endoscopic retrograde cholangiopancreatography (ERCP). All ERCP were performed by experienced biliary endoscopist. RBD was defined as a looped, sigmoid-shaped bile duct on cholangiogram with associated cholestatic liver biomarkers. Patients with biliary T-tube placement, biliary anastomotic strictures, bile leaks, bile-duct stonessludge and suspected sphincter of oddi dysfunction were excluded. Therapy included single or multiple biliary stents with or without sphincterotomy. The incidence of RBD, the number of ERCP corrective sessions, and the type of endoscopic interventions were recorded. Successful response to endoscopic therapy was defined as resolution of RBD with normalization of associated cholestasis. Laboratory data and pertinent radiographic imaging noted included the pre-ERCP period and a follow up period of 6-12 mo after the last ERCP intervention. RESULTS: One thousand two hundred and eighty-two patient records who received OLT from 1992 through 2011 were reviewed. Two hundred and twenty-four patients underwent ERCP for suspected BTC. RBD was reported in each of the initial cholangiograms. Twentyone out of 1282 (1.6%) were identified as having RBD. There were 12 men and 9 women, average age of 59.6 years. Primary indication for ERCP was cholestatic pattern of liver associated biomarkers. Nineteen out of 21 patients underwent endoscopic therapy and 2/21 required immediate surgical intervention. In the endoscopically managed group: 65 ERCP procedures were performed with an average of 3.4 per patient and 1.1 stent per session. Fifteen out of 19 (78.9%) patients were successfully

The Sendai Framework for Disaster Risk Reduction 2015–2030 recommends several actions for early warning systems(EWSs). However, there is a lack of information about their means of implementation. This article used institutional ethnography to analyze the 2012–2018 implementation of a national warning system in Brazil. The challenges related to daily activities, and the interdisciplinary works in the four axes of EWSs towards multi-hazard and people-centered approaches are discussed. This national experience is then discussed in the light of the global challenges of EWSs considering two main issues:(1) experiences of implementation and barriers related to people-centered warning systems;and(2)types of national/regional warning systems and hazards/threats that are being monitored as an important input for multi-hazard approaches. There are few multi-hazard warning systems in place and EWSs are focused on hydrometeorological hazards, mainly related to floods. The Sendai Framework needs to improve access to data and information, identify views from the frontline, consider political threats and vulnerabilities, and find ways to talk about disaster risk creation processes at a larger scale.

Chloroplasts and mitochondria genomes contain a few dozen genes required for gene expression, photosynthesis, and the electron transport chain. However, proteomic and bioinformatic studies suggest that approximately 2000 and 2600 proteins are located in plant mitochondria and chloroplasts, respectively; most of them are encoded by nuclear genes, synthesized in the cytoplasm, and targeted to organelles. Despite the simplicity of organelle genomes, their transcriptional regulation is complex and can only be partially explained by currently known transcriptional machinery components, suggesting that additional unidentified regulatory factors exist （Liere et al., 2011）.
