Relatively little is known about fatal motor vehicle accidents (FMVA) involving drivers with psychiatric disorders. In this study of all drivers killed in FMVAs in Finland between 1990 and 2011, we aimed to study drivers' death rate trends in FMVAs, with special focus on drivers with a history of psychiatric disorders. Prevalence of drivers' hospital treated psychiatric disorders, and characteristics of drivers with psychiatric disorders were also studied. For the purpose of this study, three national registers were accessed...

Adipocytokines play an important role in adipose tissue homeostasis, especially in obesity-associated disorders such as non-alcoholic fatty liver and their complications including hepatocellular carcinoma (HCC). Although visfatin is an adipocytokine highly expressed in visceral fat that has been demonstrated to play a critical role in the progression of human malignancies, little is known about the role of visfatin in HCC associated with chronic hepatitis C virus (HCV) and hepatitis B virus (HBV) infection...

BACKGROUND: Alcohol contributes to approximately 30% of all serious crashes. While the majority of drivers acknowledge the risks associated with drink-driving, a significant proportion of the population continue to engage in this behaviour. Attitudes towards drink-driving as well as personal alcohol consumption patterns are likely to underpin a driver's decision to drink-drive. These associations were explored in the current study. METHODS: A large (N=2994) cross-sectional online survey of a representative sample of drivers in Australia was conducted...

The visible-light-promoted diastereodivergent intramolecular oxyamination of alkenes and amination of unactivated C(Sp3)-H bonds is described to construct oxazolindinones, pyrrolidinones and imidazolidones via mild generation of primary amidyl radicals from functionalized hydroxylamines. A unique phenomenon on highly diastereoselective ring-opening of aziridines controlled by electron sacrifices was observed. High diastereoselective amino alcohols derivatives were obtained efficiently through this protocol in gram scales...

The ability to sense phenylthiocarbamide (PTC) bitterness represents a well-known and convenient genetic marker for human populations and biomedical studies. Two basic phenotypes can be dichotomized by PTC sensitivity: PTC-sensitive or "tester" and PTC-insensitive or "non-tester". The majority of the population (approximately 70%) belong to the PTC-sensitive phenotype, while the remaining 30% are PTC-insensitive. The distribution of PTC sensitivities varies by consumption of alcohol, bitter coffee and cigarettes...

Phospholipid vesicle (liposome) offers an aqueous compartment surrounded by lipid bilayer membranes. Various enzyme molecules have been reported to be encapsulated in liposomes. The liposomal enzyme shows peculiar catalytic activity and selectivity to the substrate in the bulk liquid, which are predominantly derived from the substrate permeation resistance through the membrane. We reported that the quaternary structure of bovine liver catalase and alcohol dehydrogenase was stabilized in liposomes through their interaction with lipid membranes...

Compared to most other alcoholic beverages, the shelf life of beer is much more limited due to its instability in the bottle. That instability is most likely to appear as turbidity (haze), even sedimentation, during storage. The haze in beer is mostly caused by colloidal particles formed by interactions between proteins and polyphenols within the beer. Therefore, beers are usually stabilized by removing at least one of these components. We developed and constructed a Saccharomyces cerevisiae strain with a proline-rich QPF peptide attached to the cell wall, using the C-terminal anchoring domain of α-agglutinin...

PURPOSE: Fusobacterium nucleatum (F. nucleatum) is a component of the human microbiome that primarily inhabits the oral cavity. It causes periodontal disease and has also been implicated in the development of human cancers. Although there are several reports of the relationship between F. nucleatum and the clinical outcome in human cancers, its prognostic significance in esophageal cancer remains unclear. EXPERIMENTAL DESIGN: We quantified F. nucleatum DNA in 325 resected esophageal cancer specimens by qPCR...

Harmful use of alcohol is one of the world's leading health risks. A positive association between certain characteristics of the urban environment and individual alcohol consumption has been documented in previous research. When developing a tool characterising the urban environment of alcohol in the cities of Barcelona and Madrid we observed that alcohol is ever present in our cities. Urban residents are constantly exposed to a wide variety of alcohol products, marketing and promotion and signs of alcohol consumption...

This study investigated the effects and mechanism of esculetin (6,7-dihydroxycoumarin) on non-alcoholic fatty liver in diabetic mice fed high-fat diet (HFD). The diabetic mice model was induced by injection of streptozotocin, after which they were fed HFD diet with or without esculetin for 11 weeks. Non-diabetic mice were provided a normal diet. Diabetes induced hepatic hypertrophy, lipid accumulation and droplets; however, esculetin reversed these changes. Esculetin treatment in diabetic mice fed HFD significantly down-regulated expression of lipid synthesis genes (Fasn, Dgat2 and Pap) and inflammation genes (Tlr4, Myd88, Nfkb, Tnfα and Il6)...

A high-speed handpiece is used in several dental procedures and the official recommendation for safe decontamination consists of rinsing with water, washing with detergent, mechanical friction, and sterilization; however, many professionals only apply 70% w/v alcohol without also cleaning the tool between patients. We performed an analysis of high-speed handpieces reprocessed only with 70% w/v alcohol and found that the methods used in clinical practice are not safe.

A highly sensitive fluorimetric assay has been developed for the evaluation of glutathione reductase (GR) activity and the screening of its inhibitors by using carbon quantum dots (CQDs) as the signal reporter. The detection mechanism is based on the following facts: (1) the fluorescence of CQDs can be quenched by Hg(II) through the strong CQDs-Hg(II) coordination; (2) GR can catalyze the reduction of oxidized glutathione (GSSG) into reduced glutathione (GSH), so that the fluorescence recovery of CQDs would take place resulting from the strong GSH-Hg(II) interaction; (3) GR can lose its catalytic reduction of GSSG in the presence of its inhibitors, which will inhibit the recovery of the quenched fluorescence of CQDs...

A high temperature diaphragm valve-based two-dimensional (2D) gas chromatography (GC×GC) with time-of-flight mass spectrometry (TOFMS) instrument, with the valve mounted directly in the GC oven, is demonstrated with separations up to 325°C. Use of the diaphragm valve allowed for the use of uncoupled carrier gas flows for (1)D (first column dimension) and (2)D (second column dimension), with a (1)D flow rate of 1ml/min, and a (2)D flow rate 3ml/min. The 3ml/min flow rate on (2)D was selected to ensure compatibility with most TOFMS detectors...

A novel polyvinyl chloride membrane chlorate (ClO3(-)) selective electrode based on modified smectite was developed for the direct determination of chlorate ions and the potentiometric performance characteristics of its were examined. The best selectivity and sensitivity for chlorate ions were obtained for the electrode membrane containing ionophore/polyvinylchloride/o-nitrophenyloctylether in composition of 12/28/60 (w/w%). The proposed electrode showed a Nernstian response toward chlorate ions at pH=7 in the concentration range of 1×10(-7)-1×10(-1)M and the limit of detection was calculated as 9×10(-8)M from the constructed response plot...
