Synergistic complex from plants Solanaceae exhibits cytotoxicity for the human hepatocellular carcinoma cell line HepG2.

Background: It had been demonstrated that sugars from various plants can act as potent agents, which induce apoptosis of cancer cells.

Methods: Using HPLC, we fractionated a mixture of two plant extracts from the plant family Solanaceae, namely Capsicum chinense and the plant family Amaryllidaceae namely Allium sativum. We evaluated the effect of different fractions on apoptosis of HepG2 cell line.

Can biofeedback training of psychophysiological responses enhance athletes' sport performance? A practitioner's perspective.

Background: In recent years, biofeedback has become increasingly popular for its proven success in peak performance training - the psychophysiological preparation of athletes for high-stakes sport competitions, such as the Olympic games. The aim of this research was to test whether an 8-week period of exposure to biofeedback training could improve the psychophysiological control over competitive anxiety and enhance athletic performance in participating subjects.
