(Elsevier Science Ltd., 2002-01-29)Abstract—A set of structurally related compounds incorporating a carbonyl group in the ortho position withregard to a phenol function were tested against the TA3 mouse carcinoma cell line and its multidrug-resistant variant ...
-
(1980)The effects of low concentrations of 4-aminopyridine (4-AP) were studied on the frog sinus venosus by means of intracellular microelectrodes. 4-AP depressed spontaneous automaticity. This effect was not reversed by atropine. ...

(1989)1. 1. In spontaneously beating preparations of sinus venosus of the chilean frog Caudiverbera caudiverbera, the electrophysiological effects of 7-O-demethylisothalicberine (7-O-DI) on transitional pacemaker cells were ...
-
(Elsevier Ltd., 2006-02-28)A series of tricyclic hydroquinones, incorporating a carbonyl group in the ortho position relative to the phenol function, were tested as inhibitors of oxygen uptake against the TA3 mouse carcinoma cell line and its ...

-
(1994)Over the last decade, a greater decrease in the ozone level has occurred in the Southern Hemisphere. For each 1% decrease in this level, a 2% increase in biologically effective radiation occurs. Aiming to evaluate the ...
-
(Springer, 2016)In order to determine the effect of a dam on metal concentrations in riverine fish species, we studied fish inhabiting the influent (Cachapoal River) and effluent (Rapel River) of the Rapel Reservoir in central Chile. Heavy ...
-
(Routledge, 2020)The aim was to assess dual- versus single-task training for motor performance and cognitive performance in adolescents. Two experiments were performed. In the first, 30 adolescents were randomized to three groups to determine ...
-
(MDPI, 2022)The Old Limachino Tomato is a valuable fruit with exceptional nutritional values and organoleptic sensory properties. However, it suffers from a short shelf-life, compromising post-harvest behavior. As an attempt to improve ...
-
(Elsevier, 2020)Chile is one of several countries that recently implemented a fiscal policy to reduce soft drink (SD) intake and obesity. In 2014 the government increased the existing ad-valorem tax on high-sugar SD by 5% and decreased ...
-
(Oxford Univ. Press Inc., 2016)Abdominal wall weakness is a consequence of rectus abdominis diastasis and flaccidity of the myofascial component. A degree of plicature of the rectus abdominis generates an increase of intra-abdominal pressure (IAP), which ...

(Springer, 2014)Epidemiological studies have reported an association between high iron (Fe) levels and elevated risk of developing type 2 diabetes mellitus (T2D). It is believed that the formation of Fe-catalyzed hydroxyl radicals may ...
-
(Springer-Verlag, 1965)1. The effects on brain weight and histological appearance of adrenalectomy, of a stereotactic cerebral lesion and of sodium chloride in drinking water were studied in 120 rats. 2. Brain edema is measured by means of ...
-
(HUMANA PRESS INC, 1999-04)A 3-wk period of stress promotes the development of ovarian cysts in rats apparently mediated by increased sympathetic nerve activity and ovarian steroid secretion. After 11 wk of stress, these parameters are indistinguishable ...
-
(Elsevier, 2015)Research on discrepancies between the actual self and ideal self has examined self-discrepancies in knowledge, skills and stature but age-based self-discrepancies have only recently received attention and so we studied ...
-
(Elsevier, 2012)We studied the effects of afforestation on soil respiration (Rs) in an arid shrubland in northern Chile. We sampled Rs monthly for three years in two adjacent plots, one left as control in natural condition, and one afforested ...
-
(1987)The effect of daily doses of 80 mg/kg (intraperitoneal) of alphamethylparatyrosine, AMPT (inhibitor of tyrosine hydroxylase) on the voluntary consumption of ethanol, water, and solid food was studied in rats of both sexes ...
