(Dirección de Bibliotecas, Archivos y Museos. Centro Nacional de Conservación y Restauración, 2003)Se desarrolló un protocolo de reconocimiento de barnices empleados en pintura de caballetes utilizando Cromatografía en Placa Fina (TLC). La identificación del barníz se realizó comparando el perfil de elusión cromatográfico ...

(1992)The major heat shock proteins from Thiobacillus ferrooxidans were identified as DnaK and GroEL equivalents by Western blotting and analysis of the N-terminal amino acid sequence of spots isolated from dried 2-D polyacrylamide ...
-
(1992)Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...

(PERGAMON-ELSEVIER SCIENCE LTD, 1992-06)Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
-
(1987)Three types of effector proteins have been isolated from a partially purified protein preparation of potato tuber. One of the proteins is a typical calmodulin which has no effect on apyrase. The two other proteins modulate ...

(1999)Electronic absorption spectra for the complexes [CpFe(dppe)NC-R]PF6 R = CH2-C6H4-ON3P3(OC 6H4t-Bu)5 (1), R = CH2-C6H4-OH (2) and R = CH3 (3) in different solvents have been measured. The two absorption bands at the lowest ...
-
(Universidad Austral de Chile, 2014)This study aimed to demonstrate for the first time the presence of Nosema ceranae in the Valparaiso District. The analised bee samples were obtained in the Valparaiso Region, between 2011 and 2012, from beehives located ...
-
(MDPI, 2018-05)The elder (Sambucus spp.) tree has a number of uses in traditional medicine. Previous studies have demonstrated the antimicrobial properties of elderberry liquid extract against human pathogenic bacteria and also influenza ...
-
(Elsevier Ltd, 2014)© 2014.Propolis is a complex hive product produced by honey bees, Apis mellifera. Its composition and biological activities depend on the vegetation where hives are placed. Propolis is often used as a food supplement. The ...

(Elsevier, 2016)'Hass' avocado is the most important avocado variety cultivated worldwide. In Chile alone, there are nearly 40,000 ha, distributed between the IV and VI regions, with production areas located close to both the coast and ...
-
(Elsevier Inc., 2014)Up to date, attempts to locate the transition state (TS) for the trapping reaction between ̇OH and ̇DMPO have been unsuccessful, and the lack of molecular mechanisms by which ̇OH binds to the spin-trap constitutes a question ...
-
(TAYLOR & FRANCIS LTD, 2003-05)The collagenous extracellular matrix (ECM) forms a stress-tolerant network that is essential for proper function of the vertebrate heart. Profound changes have been detected in the interstitial ECM concurrent with developmental ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-11-04)Hyperosmotic stress stimulates a rapid and pronounced apoptosis in cardiac myocytes which is attenuated by insulin-like growth factor-1 (IGF-1). Because in these cells IGF-1 induces intracellular Ca2+ increase, we assessed ...
-
(ACADEMIC PRESS INC, 2000-04-21)Insulin-like growth factor-1 (IGF-1) is a natural protectant of cardiac myocytes that has been shown to improve cardiac function. The role of IGF-1 in attenuating apoptosis induced by osmotic stress (sorbitol, SOR) or by ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2006)El factor de crecimiento análogo a insulina tipo 1 (IGF-1) es un péptido relacionado estructural y funcionalmente con insulina que posee efectos mitogénicos y citoprotectores. Sus efectos biológicos dependen de la activación ...
-
(Accademia Nazionale dei Lincei, 1971)From the stem bark of Strychnos Romeu Belenii Krukoff & Barneby a Loganiacea of South America, a new indolinic alkaloid has been isolated, to which the structure of II-methoxydiaboline(I) has been assigned on the basis of ...
-
(NATURE PUBLISHING GROUP, 2010-02-03)In response to stress, cells start transcriptional and transcription-independent programs that can lead to adaptation or death. Here, we show that multiple inducers of autophagy, including nutrient depletion, trigger the ...
-
(Taylor and Francis Inc., 2010)Cells respond to stress by activating cytoplasmic mechanisms as well as transcriptional programs that can lead to adaptation or death. Autophagy represents an important cytoprotective response that is regulated by both ...
