OBJECTIVE: To perform a systematic review and meta-analysis of randomized, placebo-controlled trials to assess the effect of vitamin K supplementation on insulin sensitivity. DATA SOURCES: MEDLINE, the Cochrane Library, CINAHL, Web of Science, Scopus, clinicaltrials.gov, and clinicaltrialresults.org were searched up to January 2017. Reference lists of related papers were also scanned. STUDY SELECTION: Randomized controlled trials were selected if they compared vitamin K supplementation with placebo or no treatment and reported homeostasis model assessment of insulin resistance, fasting plasma glucose, fasting plasma insulin, C-reactive protein, adiponectin, leptin, or interleukin-6 levels...

A Gram-stain-positive, rod-shaped, endospore-forming, aerobic bacterial strain, designated ISSFR-015T, was isolated from a high-efficiency particulate arrestance filter in the International Space Station and was characterized by polyphasic taxonomy. A comparative analysis of the 16S rRNA gene sequence (1494 bp) of strain ISSFR-015T showed highest similarity to Solibacillus isronensis B3W22T (98.9 %), followed by Solibacillus silvestris HR3-23T (98.6 %) and Bacillus cecembensis PN5T (96.7 %). DNA-DNA hybridization analysis revealed that the DNA relatedness values of strain ISSFR-015T with other closely related species were in the range of 41-47 % [S...

BACKGROUND: Vascular calcification is a major contributing factor to mortality in end stage renal disease (ESRD). Despite the efficacy of phosphate binders to improve hyperphosphatemia, data on vascular calcification are less clear. There seems to be a difference in attenuation or delay in progression between different binders. In this in vitro experiment we tested whether phosphate binders could limit bioavailability of vitamin K2 by undesired binding. Vitamin K-deficiency limits activation of the vascular tissue mineralization inhibitor matrix γ-carboxyglutamate (Gla) protein (MGP) thereby exacerbating vascular calcification...

Bacillus natto is commonly used in industrial production of menaquinone-7, an important vitamin which plays a crucial role for blood clotting and may contribute to prevention of cardiovascular disease and osteoporosis. This study determined the optimal combination of key nutrients and established an effective use of surfactant in a coupling medium to enhance the yield of extracellular MK-7. MK-7 yield of 31.18 mg/L was achieved under optimal conditions containing 53.6 g/L glycerol, 100 g/L soy peptone, and 10 g/L K2HPO4...

A novel Gram-negative and rod-shaped bacterial strain, designated as 16F6E(T), was isolated from a water sample. Cells were yellowish in color and catalase- and oxidase-positive. The strain grew at 10-37°C (optimum at 25°C) but not at 4 and 42°C, and pH 5-7 (optimum at pH 7). It showed moderate resistance to gamma-ray irradiation. Comparative phylogenetic analysis showed that strain 16F6E(T) belonged to the family Cytophagaceae of the class Cytophagia.
