(Sociedad Chilena de Quimica, 2010)D-Glucose derivatives 1,2:5,6-di-O-isopropyline-a-D-glucofuranose (1) and 1,2-O-isopropyline-a-D-glucofuranose (2) with Ti(IV) are chiral catalysts in the addition of diethylzinc to benzaldehyde. The Ti(IV)-carbohydrate ...
-
(SOC BRASILEIRA QUIMICA, 2009)A derivative of D-xylose, 1,2-O-isopropylidene-alpha-D-xylofuranose (1), with Ti((OPr)-Pr-i)(4) was used as a chiral catalyst in the asymmetric alkylation of benzaldehyde with diethylzinc (Et2Zn) for the high-yield production ...
-
(WILEY-V C H VERLAG GMBH, 2006-01-30)The development of a new method for the diamination of alkenes is reported. It is based on a reaction in the presence of stoichiometric or catalytic amounts of chiral auxiliaries, which permits the direct synthesis of ...
-
(MDPI, 2015)During the last decade, many berry-type fruits have been recognised as good sources of anthocyanins. Nevertheless, the use of anthocyanins in the development of food colourants and healthy and/or functional ingredients ...
-
(MDPI, 2018-05)Here we report the incorporation of gold nanostructures (nanospheres or nanorods, functionalized with carboxylate-end PEG) and curcumin oil-in-water (O/W) nanoemulsions (CurNem) into alginate microgels using the dripping ...
-
(2010)Pomegranate (Punica granatum) bioactive compounds (polyphenols and anthocyanins) of juice (PJ) and ethanolic extracts (PE) were encapsulated with maltodextrin (MD) or soybean protein isolates (SPI) by spray drying using a ...
-
(Elsevier, 2015)Cactus pear (Opuntia ficus-indica) pulp (CP) was encapsulated with a soybean protein isolate (SPI) and an SPI blend with maltodextrin (MD) or inulin (I). A 22 statistical factorial design for each system (CP-SPI, CP-(SPI ...
-
(American Physiological Society, 2013)Ferritin, a food constituent of animal and vegetal origin, is a source of dietary iron. Its hollow central cavity has the capacity to store up to 4,500 atoms of iron, so its potential as an iron donor is advantageous to ...
-
(SpringerNature, 2021)Subcellular organelles communicate with each other to regulate function and coordinate responses to changing cellular conditions. The physical-functional coupling of the endoplasmic reticulum (ER) with mitochondria allows ...
-
(Elsevier, 2012)Endoplasmic reticulum (ER) stress activates an adaptive unfolded protein response (UPR) that facilitates cellular repair, however, under prolonged ER stress, the UPR can ultimately trigger apoptosis thereby terminating damaged ...
-
(2002)Objetives: To compare endothelium-dependent vasomotor response in healthy younger and older subjects without classic cardiovascular risk factors, with high and normal fasting homocysteine (tHcy) levels. Design: We compared ...
-
(Elsevier Ireland Ltd, 2019)The endothelin-1 (ET-1) axis contributes to the pathophysiology of several cancers by promoting tumor development and progression. This peptide is activated from its precursor, big ET-1, by endothelin-converting enzyme-1 ...
-
(2012)It was examined the efficacy of Monascus purpureus standardized extract (Mp) on the endothelial dysfunction (ED) of rat aortic rings caused by oxidative stress as a consequence of their exposition to a high glucose ...

(Universidad de Chile, 1987)
-
(MDPI, 2021)Gold nanoparticles (AuNP) capped with biocompatible layers have functional optical, chemical, and biological properties as theranostic agents in biomedicine. The ferritin protein containing in situ synthesized AuNPs has ...
-
(Wiley & Sons, 2015)The incorporation of carbon nanotubes to a Nafion/tetraruthenated cobalt porphyrin/glassy carbon electrode (GC/Nf/CoTRP vs GC/Nf/CNTCoTRP) enhanced the amperometric determination of hydrogen peroxide. Both electrodes ...
-
(2005)We have investigated the riboflavin (RF)-sensitized inactivation of glucose 6-phosphate dehydrogenase (G6PD) in the presence and absence of trans-urocanic acid (UCA). The inactivation of the enzyme results from its direct ...
-
(Colegio Químico Farmacéutico de Chile, 2000)¿Se ha detenido a pensar la cantidad de tecnología computacional que nos ha invadido los últimos años? Posiblemente ya haya escuchado hablar de electrodomésticos que se conectan a la Internet, y del refrigerador que tiene ...
-
(1993)A differential pulse polarographic method for the identification and quantitative determination of enoxacin is described. The method is based on the electrochemical reduction of the drug at the dropping mercury electrode. ...
