Norovirus (NoV) is recognized as the most common cause of foodborne outbreaks. In 2014, an outbreak of acute gastroenteritis occurred on a cruise ship in Brazil, and NoV became the suspected etiology. Here we present the molecular identification of the NoV strains and the use of sequence analysis to determine modes of virus transmission. Food (cream cheese, tuna salad, grilled fish, orange mousse, and vegetables soup) and clinical samples were analyzed by ELISA, conventional RT-PCR, qRT-PCR, and sequencing...

PURPOSE: Active patient engagement is increasingly viewed as essential to ensuring that patient-driven perspectives are considered throughout the research process. However, guidance for patient engagement (PE) in HRQoL research does not exist, the evidence-base for practice is limited, and we know relatively little about underpinning values that can impact on PE practice. This is the first study to explore the values that should underpin PE in contemporary HRQoL research to help inform future good practice guidance...

Venous thromboembolism (VTE) is a multifactorial disease determined by a combination of inherited and acquired factors. Inherited factors include mutations in the genes coding for coagulation factors, some of which seem to exert a differential influence on the risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE). In post-mortem studies of subjects who have died from pulmonary embolism (PE), the analysis of the factors that may have augmented the VTE risk is often limited to acquired factors...

Pulmonary embolism(PE)in the early phase of stroke worsens the prognosis. It is necessary to detect deep venous thrombosis(DVT)to avoid PE. We conducted the D-dimer screening in order to detect DVT at an earlier stage. We retrospectively analyzed the clinical data of patients with hemorrhagic stroke who were admitted to the local stroke center, and investigated the complication rates of DVT, PE, D-dimer values, and risk factors of DVT. From October 2012 to August 2014, 261 patients were included. DVT was detected in 46 patients(17...

Obesity is associated with structural and functional changes in the perivascular adipose tissue (PVAT), favoring the release of reactive oxygen species (ROS), vasoconstrictor and proinflammatory factors. Tumor necrosis factor alpha (TNF-α) induces vascular dysfunction and is produced by the PVAT. We tested the hypothesis that obesity-associated PVAT dysfunction is mediated by augmented mitochondrial ROS (mROS) generation due to increased TNF-α production in this tissue. Aortae from high fat diet (HFD)-fed obese mice displayed increased contractions to phenylephrine (PE) and loss of PVAT anticontractile effect...

A Gram-stain-negative, oxidase-negative, catalase-positive, facultative anaerobe, designated XJ16T, was isolated from a marine solar saltern on the coast of Weihai, China. Cells of the strain XJ16T were long and rod-shaped. The colonies were ochre in color and were able to reduce nitrate to nitrite. Optimal growth occurred at 33-37 °C (range, 20-45 °C) and in the presence of 8-10 % (w/v) NaCl (range, 2-20 %, w/v). The pH range for growth was found to be 6.5-9.5, with optimum growth at pH 7.5-8.0. A phylogenetic analysis based on the 16S rRNA gene sequence demonstrated that strain XJ16T was related to the phylum Proteobacteria...

Background - Preeclampsia (PE) is pregnancy-induced hypertension with proteinuria that typically develops after 20 weeks of gestation. Anti-hypertensives currently used for PE reduce blood pressure of PE mothers, but do not prevent pre-term delivery, and do not alleviate fetal growth restriction (FGR) associated with PE. We have recently shown that the activation of the ET system exacerbates PE. However, ET receptor antagonists are teratogenic and not suitable for pregnant women. A vitamin B3 nicotinamide (Nam) inhibits vasoconstriction by ET, is generally considered safe and harmless to babies...

Using a transgenic cross, we evaluated features of preeclampsia, renal injury and the sFlt1/VEGF changes. Transgenic hAGT and hREN, or wild type (WT) C57Bl/6 mice were cross-bred: ♀hAGT x ♂hREN for preeclampsia (PRE) model and ♀WT x ♂WT for pregnant controls (WTP). Samples were collected for plasma VEGF, sFlt1 and urine albumin. Blood pressures (BP) were monitored by telemetry. Vascular reactivity was investigated by wire myography. Kidneys and placenta were immunostained for sFlt1 and VEGF. Eleven PRE and 9 WTP mice were compared...

BACKGROUND: Mutations in Lipopolysaccharide-induced tumour necrosis factor-α factor (LITAF) cause the autosomal dominant inherited peripheral neuropathy, Charcot-Marie-Tooth disease type 1C (CMT1C). LITAF encodes a 17 kDa protein containing an N-terminal proline-rich region followed by an evolutionarily-conserved C-terminal 'LITAF domain', which contains all reported CMT1C-associated pathogenic mutations. RESULTS: Here, we report the first structural characterisation of LITAF using biochemical, cell biological, biophysical and NMR spectroscopic approaches...

Pharmacokinetic drug-drug interactions are frequently characterized and quantified by an AUC ratio (Rauc). The typical value of the AUC ratio in case of cytochrome-mediated interactions may be predicted by several approaches, based on in vitro or in vivo data. Prediction of the interindividual variability of Rauc would help to anticipate more completely the consequences of a drug-drug interaction. We propose and evaluate a simple approach for predicting the standard deviation (sd) of Ln(Rauc), a metric close to the interindividual coefficient of variation of Rauc...
