(1999)1. Fenoldopam mesylate, a benzazepine derivative, is a D1 receptor agonist that lowers blood pressure through vasodilation of renal, mesenteric, coronary and cerebral vascular beds. 2. Experiments were performed in rats, ...
-
(Springer New York LLC, 2018)© 2018 American Association of Pharmaceutical Scientists The buccal mucosa appears as a promissory route for biologic drug administration, and pharmaceutical films are flexible dosage forms that can be used in the buccal ...
-
(1968)The free radicals induced by gamma radiation in deaerated aqueous solutions of 2′‐3′ uridylic acid at 77°K have been studied by electron spin resonance techniques. The annealing at 193°K of the OH radical trapped at 77°K ...
-
(Elsevier, 2017)We studied the effect of gold nanoparticle (AuNP) size, surface charge, concentration and morphology on the integrity of the blood–brain barrier (BBB) in a well-established in vitro model set-up. We focused on the effect ...
-
(Royal Soc. Chemistry, 2018-05)In Latin America many mine sites are located more than 2000 m above sea level, and some over 4000 m above sea level. Portable X-ray ray fluorescence (pXRF) is becoming a routine method for collecting chemical data at ...
-
(ELSEVIER SCIENCE BV, 2002-05-09)Eighty-two amino acid sequences of the catalytic domains of mature endoxylanases belonging to family 11 have been aligned using the programs MATCHBOX and CLUSTAL. The sequences range in length from 175 to 233 residues. The ...
-
(Nature Publishing Group, 2017)Knots are natural topologies of chains. Yet, little is known about spontaneous knot formation in a polypeptide chain-an event that can potentially impair its folding-and about the effect of a knot on the stability and ...

-
(Academic Press Inc., 1998)We have analyzed the role of mesoderm in the induction of the neural crest in Xenopus using expression of neural plate (Xsox-2) and neural crest (Xslug and ADAM). Conjugation experiments using different kinds of mesoderm ...
-
(2005)Changes in pH, total volatile basic nitrogen (TVB-N) and K-value were determined in golden kingclip species (Genypterus blacodes) frozen and stored at -18°C and -30°C for 6 months and golden kingclip canned fish in two ...
-
(Dovepress, 2021)The physicochemical and optical properties of silver nanoparticles (SNPs) and gold nanoparticles (GNPs) have allowed them to be employed for various biomedical applications, including delivery, therapy, imaging, and as ...
-
(1995)This work reports a comparative study of the catalytic behaviour for a series of metallocenes derived from Ti, Zr, Hf and Nb, which after activation with methylaluminoxane can polymerize ethylene. Results show that the Zr ...
-
(1987)A complete description of the rotational isomerism of monothioformic acid is presented. Ab initio results concerning the barrier heights and the energy difference between the stable isomers are in good agreement with the ...

-
(2013)In the structure of the title compound, {[Cu-2(C10H2O8)-(H2O)(6)]center dot 4H(2)O}(n), the benzene-1,2,4,5-tetracarboxylate ligand, (btec)(4-), is located on a crystallographic inversion centre in a 4-coordination mode. ...
-
(1992)A protein isolated and purified from the outer membrane of the acidophilic, chemolithotrophic bacterium, Thiobacillus ferrooxidans with an oligomeric molecular weight of 90 000 Da (p9O) was incorporated into phosphatidyl ...
-
(MDPI, 2018)The microencapsulation of maqui juice by spray-drying and freeze-drying was studied as a strategy to protect anthocyanins in new food formulations in order to improve the anthocyanin retention before consumption and the ...
-
(2012)Shigella flexneri causes bacillary dysentery in humans. Essential to the establishment of the disease is the invasion of the colonic epithelial cells. Here we investigated the role of the lipopolysaccharide (LPS) O antigen ...
