(2013)We report for the first time the use of double stranded calf-thymus DNA (dsDNA) to successfully disperse bamboo-like multi-walled carbon nanotubes (bCNT). The dispersion and the modified electrodes were studied by different ...
-
(Dustri-Verlag Dr. Karl Feistle, 1987)Dibekacin pharmacokinetics was studied in ten healthy volunteers and six patients with renal failure presenting Clcr<10ml.min-1 per 1.73m2 of body surface, given as a low intravenous bolus to the volunteers and as 30-minute ...

(Dustri-Verlag Dr Karl Feistle, 1995-11)Dibekacin pharmcokinetics was studied in 3 healthy volunteers, 5 patients with renal failure presenting Cl-cr, between 4.0 and 67 ml min (-1) per 1.73 m(2) of body surface and 5 anephric patients given as a 30 minute ...
-
(Elsevier Science Publishers B. V., 1990)The ribosomal protein S4 from Escherichia coli is essential for initiation of assembly of 30S ribosomal subunits. We have undertaken the identification of specific features required in the 16S rRNA for S4 recognition by ...

Dissolution kinetics evaluation of controlled-release tablets containing propranolol hydrochloride (Marcel Dekker Inc., 1999)In the present research, controlled-release propranolol hydrochloride tablets were prepared for twice-daily administration, allowing more uniform plasmatic levels of the drug. Pharmaceutical formulations were prepared with ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2003-02-01)The contribution of distinct Ca2+-sensitive protein kinases to the regulation of the expression of the synaptosomal-associated protein SNAP-25 was examined in bovine chromaffin cells. Prolonged incubation with high K+ (38 ...
-
(1979)Mössbauer spectroscopy as a function of temperature of Fe(II)(N,N′-dicyclohexyl-thiourea)6(ClO4)2(FeDCTU) shows the existence of two isomeric forms A and B which coexist in the temperature range 200 < T < 300 K. The relative ...
-
(Sociedad Chilena de la Ciencia del Suelo, 2000)Universalmente se hace necesario y urgente implementar políticas de uso de residuos orgánicos en los suelos, tanto por la necesidad de disponer de estos residuos, como también por la necesidad apremiante de recuperar el ...
-
(ELSEVIER, 2008-01-30)The distribution of urocanic acid (UCA) isomers between aqueous solutions and n-octanol, egg yolk phosphatidylcholine (eggPC) liposomes or bovine serum albumin (BSA) has been evaluated. Regarding its partitioning between ...

(2013)Background: Paper mulberry has been used for thousands of years in Asia and Oceania for making paper and bark-cloth, respectively. Museums around the world hold valuable collections of Polynesian bark-cloth. Genetic ...
-
(Kluwr Academic Publisher, 1999)Traditional identification of peach and nectarine varieties relies on the assessment of agronomic traits of the adult plant. This leads to a significant delay of time, constraints to breeders in the surveillance of germplasm ...
-
(Journal of Visualized Experiments, 2018)DNA staining methods are very important for biomedical research. We designed a simple method that allows DNA visualization to the naked eye by the formation of a colored precipitate. It works by soaking the acrylamide or ...
-
(PLoS ONE 8(11): e79499, 2013)The constant emergence of antibiotic multi-resistant pathogens is a concern worldwide. An alternative for bacterial treatment using nM concentrations of tellurite was recently proposed to boost antibiotic-toxicity and a ...
