The main goal of the study is to produce eco-friendly furniture dyes by using bio-colorants and determine color stability these in outdoor conditions. In this regard, dye extracts obtained from red beet (Beta vulgaris), safflower (Carthamus tinctorius L.), purple cabbage (Brassica oleracea), as a bio-colorant source, were applied MDF test panels mixing with water-based synthetic lacquer coating...

Melanin is a recognized virulence factor in Cryptococcus neoformans; several pathogenetic mechanisms have been suggested. We studied melanin as an antifungal resistance factor. The growth of laccase-active strains of C. neoformans and C. albidus in L-DOPA resulted in the production of black pigment. The formal minimal inhibitory concentrations (MICs) of amphotericin B and fluconazole were not c...

conclusions religiosity has been used as a coping mechanism among blacks. religiosity may also be related to stress regulation among black youth. future studies need to test complex associations between race, sex, religiosity, chronic stress, coping, and function of hypothalamo-pituitary-adrenal (hpa). it is not known whether male black youth who are and those who are not religious differently ...

Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

The photocatalytic degradation of Diamond green B, a triarylmethane dye, has been investigated in aqueous heterogeneous solutions containing TiO2 nano- particles as photocatalysts. The factors effective on the degradation of Diamond green B, such as the amount of catalyst, the original concentration of dye, the effect of pH and illumination time were investigated under 400 W high pressure mercu...

BACKGROUND Thoracic epidural anesthesia (TEA) is frequently used to maintain intraoperative analgesia. After injecting the initial bolus dose of epidural local anesthetics (LA), intermittent injection of LA through an epidural catheter is required to maintain the intraoperative analgesia. For intermittent epidural administration, usually 2 - 5 mL of LA has been used. However, no studies have su...
