The devastating effects of drought on agriculture, water resources, and other socioeconomic activities have severe consequences food security resource management. Understanding the mechanism that drives predicting its variability is important for enhancing early warning disaster risk In this study, meteorological droughts over six coastal synoptic stations were investigated using three-month St...
The fragment ablation rate plays significant roles in the mitigation efficiency of Shattered Pellet Injection (SPI) as a Disruption Mitigation System (DMS). Current mainstream 3D MHD codes modelling SPIs mostly assume instantaneous thermalization between previously hot ambient electrons and newly released cold electrons, which results underestimation if electron time is comparable or even longe...
BACKGROUND Surgeries are inevitable for treating primary congenital glaucoma (PCG) and risk factors of surgical failure play a key role in surgical decision making. The aim of this study was to investigate the influence of delay of surgery and preoperative speed of progression (SP) on the surgical outcomes in these patients. METHODS Medical records of 83 eyes of 51 PCG patients with trabeculo...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a deadly pneumonia caused by an enveloped, single-stranded positive-sense RNA (+ssRNA), 29.881 kb betacoronavirus, belonging to the coronaviridae 2B lineage.1 Clinically, about 80% of patients with Covid-19 develop asymptomatic or mild illness, usually within 12 days, whereas 15-30% progress severe disease distress (ARDS), hypoxaem...
BACKGROUND Salmonella enterica serotype Paratyphi A is a human-restricted cause of paratyphoid fever, accounting for up to a fifth of all cases of enteric fever in Asia. METHODOLOGY/PRINCIPAL FINDINGS In this work, we applied an RNA analysis method, Selective Capture of Transcribed Sequences (SCOTS), and cDNA hybridization-microarray technology to identify S. Paratyphi A transcripts expressed...
This paper presents an analysis of imperative formation in Norwegian. The analysis occasions discussion of variation as reranking in OT, as well as providing a novel example of a grammar in which 'null' is the optimal candidate. The Norwegian imperative is in most cases identical to the verb stem (cf. Faarlund, Lie & Vannebo 1997:477). For verbs having the familiar disyllabic structure with a f...
Salmonella enterica infections result in diverse clinical manifestations. Typhoid fever, caused by S. enterica serovar Typhi (S. Typhi) and S. Paratyphi A, is a bacteremic illness but whose clinical features differ from other Gram-negative bacteremias. Non-typhoidal Salmonella (NTS) serovars cause self-limiting diarrhea with occasional secondary bacteremia. Primary NTS bacteremia can occur in t...
Serine protease inhibitors (SPIs) are a superfamily of structurally related but functionally diverse proteins found in almost all organisms ranging from viruses to humans. Some of them play important roles in host defense. A recently identified SPI from the eastern oyster (Crassostrea virginica), cvSI-1, has been shown to inhibit the proliferation of the Dermo pathogen Perkinsus marinus in vitr...
The type VI secretion system (T6SS) is a virulence factor for many Gram-negative bacteria. Salmonella genus harbors five phylogenetically distinct T6SS loci encoded in Salmonella Pathogenicity Islands (SPIs) SPI-6, SPI-19, SPI-20, SPI-21 and SPI-22, which are differentially distributed among serotypes. The T6SSs encoded in SPI-6 and SPI-19 contribute to pathogenesis of serotypes Typhimurium and...
Objective: To investigate prevalence of acute diarrhea in Shanghai and analyze virulence associated-genes and antibiotic resistance of major enteropathogens using combination of conventional and molecular epidemiology methods. Method: The 412 stool specimens were obtained by systematic sampling from diarrhea patients throughout entire year 2016. Bacterial and viral pathogens were identified and...
