Lignin is Nature’s major source of aromatic chemistry and by many seen as the green entry-point alternative to fossil-based chemical industry. Due its chemically recalcitrant structure, utilization lignin challenging, wherein enzymes might be key overcome this challenge. Here, we focus on characterization dye-decolorizing peroxidases from Streptomyces coelicolor A3(2) (ScDyPs) in context enzyma...

Fluorescent nucleic acid hybridization probes traditionally have been generated by enzymatic incorporation of dye-labeled nucleotides, even though incorporation efficiency is low and variable from dye to dye. Alternatively, 5-(3-aminoallyl)-2'-deoxyuridine 5'-triphosphate (aa-dUTP) is enzymatically incorporated to generate amine-modified DNA, which is then chemically labeled with an amine-react...

introduction: basal cell carcinoma (bcc) is the most common cutaneous malignancy. proffered treatment for these lesions is surgery. based on patient’s age, drug allergies, and place of lesions, surgery may not be the best option, and alternative treatments should be considered. pulsed dye laser (pdl) may be a good alternative therapy. the aim of the present study was to determine the effectiven...

In this work, new coumarin based dyes for dye sensitized solar cells (DSSC) have been designed by introducing several substituent groups in different positions of the NKX-2311 structure. Two types of substitutions have been considered: the introduction of three electron-donating groups (-OH, -NH(2), and -OCH(3)) and two different substituents with steric effect: -CH(2)-CH(2)-CH(2)- and -CH(2)-H...

Dye-sensitized solar cells (DSSCs) are considered a promising future source of low-cost solar power. At present, however, the most efficient DSSC designs utilize iodide-based electrolytes, which are highly corrosive and absorb strongly in some regions of the visible spectrum. We have been able to generate significant efficiency increases in DSSCs employing a novel sulfide/thiolate redox couple ...

Concentration-related dye leakage produced by intracutaneous injections of irritants was measured in rats by an Evans blue technique. 2 In rats pretreated with a total dose of 50 mg capasaicin over 4 days, the response to capsaicin, formalin, HCl, KCl, prostaglandin E1, bradykinin and bradykinin with prostglandin E1 (10(-6) M) were greatly reduced, the responses to histamine and 5-hydroxytrypta...
