The antibiotics roseoflavin and 8-demethyl-8-amino-riboflavin from Streptomyces davawensis are metabolized by human flavokinase and human FAD synthetase
(Pergamon-Elsevier B.V. Ltd, 2011-12-15)
The non-pathogenic Gram-positive soil bacterium Streptomyces davawensis synthesizes the riboflavin (vitamin B(2)) analogs roseoflavin (RoF) and 8-demethyl-8-amino-riboflavin (AF). Both compounds are antibiotics. Notably, ...
Morphometry and histochemistry of the semitendinosus muscle of tufted capuchin monkeys (Cebus apella Linnaeus, 1758)
(Blackwell Verlag Gmbh, 2003-08-01)
Considering monkeys are animals closely related to the human, and semitendinosus muscle has been used in many postural research experiments, we have decided to study its histochemical characteristics. Samples were removed ...
Morphometric and histochemical study of the human vocal muscle
(Annals Publ Co, 2000-01-01)
The present study was conducted on vocal muscles removed at autopsy Rom adult individuals (10 men and 8 women, aes ranging from 48 to 78 years) with no laryngeal disease. Histologic analysis was performed with hematoxylin ...
Molecular model of cyclin-dependent kinase 5 complexed with roscovitine
(Elsevier B.V., 2002-10-11)
Here is described a structural model for the binary complex CDK5-roscovitine. Roscovitine has been shown to potently inhibit cyclin-dependent kinases 1, 2 and 5 (CDK1, 2, and 5), and the structure of CDK2 complexed with ...
Angiotensin II chronic infusion induces B1 receptor expression in aorta of rats
(Lippincott Williams & Wilkins, 2007-10-01)
We investigated whether angiotensin II infusion modulates in vivo the kinin B1 receptor expression and the mechanisms involved in this process. We also evaluated the role of the B1 receptor activation in aorta. Wistar rats ...
Evaluation of the interactions of DNA with the textile dyes Disperse Orange 1 and Disperse Red 1 and their electrolysis products using an electrochemical biosensor
(2013-02-11)
A disposable pencil graphite electrode modified with dsDNA was used in combination with square wave voltammetry in order to evaluate the interaction of DNA with the textile dyes Disperse Orange 1 (DO1) and Disperse Red 1 ...
Role of nitric oxide in the remodelling of extracellular matrix in myxomatous mitral valve degeneration of dogs and pigs
(2011-11-01)
Myxomatous mitral valve degeneration (MMVD) or endocardiosis is a heart valve disease that occurs in many mammalian species, especially in humans, dogs and pigs. Nitric oxide (NO) plays an important role in the MMVD ...
Kinetic aspects of rat (Rattus-norvegicus albinus) submandibular glands lactic-dehydrogenase
(Inst Tecnologia Parana, 1994-01-01)
Submandibular glands of male rats were homogenized with 33 mM sodium potassium phosphate buffer, pH 6.5, containing 1 mM MgCl2 and 0.1 mM DTT and purified with ammonium sulphate, phosphocellulose chromatography, eluted ...
