ObjectiveTo prevent the occurrence of CV events such as MI and stroke among professional drivers in Korea, bus drivers were compared to other occupations through the Framingham risk scoring system (FRS) or metabolic syndrome (MS) of cardiovascular disease (CVD) risk assessment methods.MethodsIn October 2012, a health examination survey was conducted for 443 male bus drivers in a big city. Their CVD risk factors were compared to those of a ‘total employed’ (A group) and ‘crafts and machine operators’ (B group) extracted from Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2010) data by using FRS and MS. We calculated proportions of the CVD risk factors distribution between bus drivers and the A, B groups by the bootstrapping method. The Odds ratio (OR) between CV event risk combining MS with CHD equivalent risk of FRS and occupational factors like shift patterns and professional driving duration/age ratios (PDAR) of bus drivers was calculated through multinominal logistic regression.ResultsThe proportion of BMI ≥ 25 kg/m2 was 53.9% and waist circumference ≥ 90cm was 40.9% among bus drivers. Hypertension and MS prevalence of bus drivers was 53.3%, 49.9% which is higher than 17.6%, 22.6% in the A group and 19.7%, 23.8% in the B group respectively. OR of high CV event risk in alternate shift was 2.58 (95% CI 1.33~5.00) in comparison with double shift pattern and OR in PDAR ≥ 0.5 was 2.18 (95% CI 1.15~4.14).ConclusionMiddle aged male drivers in a big city of Korea stand a higher chance of developing CV event than other professions of the same age.

Oxidation of alcohols is an essential organic reaction, affording versatile carbonyl groups. To provide a sustainable solution for environmentally harmful traditional oxidation methods, the transition-metal catalyzed acceptor-free dehydrogenation of alcohols has attracted much attention. The widely used catalysts for the dehydrogenation reaction are based on precious metals, which are not economical and environmentally benign. We developed an operationally simple, economical, and environmentally benign acceptorless Fecatalyzed dehydrogenation of various secondary benzylic alcohols to afford the corresponding ketones and H 2 . A simple in situ mixture of readily available Fe(III) acetylacetonate, 1,10-phenanthroline, and K 2 CO 3 was identified as an active catalyst for this transformation.

The Transmissible Gastroenteritis Virus (TGEV) causes severe diarrhea and other symptoms which end up in death in young piglets. We have studied the protective effects of the probiotic Lactobacillus plantarum strain N4(Lp) which metabolic products were added to the swine testis (ST) cells with three different orders using MTT cell proliferation assay and CPE analysis. Metabolic products led to dose-dependent rescue of viability of infected cells in a certain order: pre-treatment, post-infection, co-incubation. Pre-treatment of cells with probiotic metabolic products reduced viral proliferation up to 78% at non-cytotoxic concentration 1/4 dilution. The viral yields in pretreatment groups were reduced by over three log10 units. Quantitative real-time PCR revealed the optimal inhibition of TGEV RNA replication was 24 h apply pretreatment way that up to 71% of N gene. Analysised the composition of metabolic products by GC-MS revealed the major component is sugars. Then Exopolysaccharides (EPS) was extracted and showed inhibition effect that co-incubation with TGEV.
