Structural antitumoral activity relationships of synthetic chalcones
(2009)
Relationships between the structural characteristic of synthetic chalcones and their antitumoral activity were studied. Treatment of HepG2 cells for 24 h with synthetic 2'-hydroxychalcones resulted in apoptosis induction ...
Cardiovascular remodeling induced by passive smoking
(2009-12-01)
Coronary heart disease (CHD) is the most common cause of death in many developed countries. The major risk factors for CHD are smoking, high blood pressure, diabetes, high cholesterol levels, and lack of physical activity. ...
The relationship between physical activity intensity and domains with cardiac autonomic modulation in adults: An observational protocol study
(2019-10-01)
Introduction:Cardiac autonomic modulation is an important marker of cardiovascular health and the practice of physical activity is a fundamental tool for good maintenance or increments in this marker. However, it is not ...
Long-term facilitation of expiratory and sympathetic activities following acute intermittent hypoxia in rats
(2016-07-01)
Aim: Acute intermittent hypoxia (AIH) promotes persistent increases in ventilation and sympathetic activity, referred as long-term facilitation (LTF). Augmented inspiratory activity is suggested as a major component of ...
Effects of physical activity on the P300 component in elderly people: a systematic review
(Wiley-Blackwell, 2017-11-01)
The effects of physical activity on brain function can be assessed through event-related potentials (P300) that reflect cortical activities related to cognitive functions. P300 latency represents the information processing ...
Studies on quinones. Part 43: Synthesis and cytotoxic evaluation of polyoxyethylene-containing 1,4-naphthoquinones
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A series of naphthoquinones 2,3-disubstituted with chlorine and oxyethylene groups have been prepared from 2,3-dichloro- and 2,3-dimethoxy-1,4-naphthoquinone. The members of these series were tested on normal human. broblasts ...
Structure-antioxidant activity relationships of flavonoids isolated from the resinous exudate of Heliotropium sinuatum
(Pergamon-Elsevier Science Ltd., 2005)
Effect of light-curing on the antibacterial activity of dentin bonding agents
(2009)
Aim: This study evaluated the effect of light-activation on the antibacterial activity of dentin bonding systems. Methods: Inocula of Streptococcus mutans and Lactobacillus casei cultures were spread on the surface of BHI ...
Resveratrol isoforms and conjugates: A review from biosynthesis in plants to elimination from the human body
(2020-01-01)
The natural isomers of resveratrol, cis- and trans-resveratrol, are natural phenolic substances synthetized via the shikimate pathway and found in many sources, including grapes, peanuts, blackberries, pistachios, cacao, ...
