(1995)Bromination of 2,4,6-tri-O-benzoyl-3-deoxy-d-erytro-hex-2-enono-1,5-lactone (1) took place diastereoselectively to afford a single product: 2,4,6-tri-O-benzoyl-2,3-dibromo-3-deoxy-d-altrono-1,5-lactone (2). The configuration ...
-
(MDPI, 2021)Currently, most vaccines available on the market are for parental use; however, this may not be the best option on several occasions. Mucosal routes of administration such as intranasal, sublingual, and buccal generate ...

Buccal delivery of small molecules and biologics: of mucoadhesive polymers, films, and nanoparticles (Elsevier, 2017)Buccal delivery of macromolecules (biologics) sets a great challenge for researchers. Although several niche small molecule products have been approved as simple sprays, tablets and oral films, it is not simply a case of ...
-
(Springer New York LLC, 2017)© 2016, American Association of Pharmaceutical Scientists. The development of an appropriate dosage form for pediatric patients needs to take into account several aspects, since adult drug biodistribution differs from that ...
-
(Universidad de Chile, 1997)Cuando Platón regresó a Atenas en el año 387 a.C., se estableció una escuela de filosofía en un jardín, a poco más de 1 Km. de distancia de la ciudad, con olivos, estatuas y templos, denominado Academos, en honor a su ...
-
(ELSEVIER, 2010)Substantial progress has been made throughout the last decades in the elucidation of the key players and mechanisms responsible for Ca2+ signal generation in both excitable and non-excitable cells. Importantly, these ...
-
(SPRINGER VERLAG, 1998-01)Heavy metals participate in complex biogeochemical cycles whose final destination (except on a geological scale)is the bottom of oceans and lakes. This implies that to reach the bottom the metals of the sediment have to ...
-
(Universita degli Studi di Pisa, Istituto di Chimica Agraria, 1992)Wasterwastes of municipal and industrial origin used to irrigate farmlands contain heavy metals which are sorbed on the surfaces of soil particles. Among those metals are cadmium (Cd) and copper(Cu). The degree to which ...
-
(Elsevier, 2013)Ceramides are important intermediates in the biosynthesis and degradation of sphingolipids that regulatenumerous cellular processes, including cell cycle progression, cell growth, differentiation and death. In ...
-
(1997)In toad olfactory neurons, a putrid odorant mixture inducing inhibitory responses increases Ca2+-activated K+ conductance, developing a hyperpolarizing receptor potential. Removal of extracellular Ca2+ or exposure to ...
-
(Wiley, 2017-04)Calcium (Ca2+) is a key player in the regulation of many cell functions. Just like Ca2+, mitochondria are ubiquitous, versatile, and dynamic players in determining both cell survival and death decisions. Given their ...
-
(Sociedad Chilena de Nutrición, Bromatología y Tecnología, 1982)The evaluation of the sensorial quality of tea was developed in order to complement the information obtained from physico-chemical analysis performed on different types of tea. The work was carried on with 12 samples, ...
-
(ELSEVIER SCIENCE BV, 2010-03)Type-2 ryanodine receptors (RyR2) - the calcium release channels of cardiac sarcoplasmic reticulum - have a central role in cardiac excitation-contraction coupling. In the heart, ischemia/reperfusion causes a rapid and ...

Capillary electrophoretic determination of ions in soils / determinación de iones en suelos por ... (SOCIEDAD CHILENA DE QUIMICA, 1997-12)The applicability, sensitivity and repetitivity, as well as general aspects of the Capillary Zone Electrophoresis (CZE) technique was studied as applied in the identification and quantification of Cl-, NO3-, HCO3-, SO42-, ...
-
(ELSEVIER SCI LTD, 2002-03)Capillary zone electrophoresis (CZE) was used to study the effect of frozen storage on the electrophoretic patterns of sarcoplasmic proteins (SAR) extracted from fillets of golden kinglip (Genypterus blacodes) species using ...
-
(Springer, 2016)Highly fluorescent nanoparticles, or quantum dots, have multiple applications in biology and biomedicine; however, in most cases, it is necessary to functionalize them to enhance their biocompatibility and selectivity. ...
