We consider cosmological implications of the formula for the dark energy density derived by Gurzadyan and Xue [1] which predicts a value fitting the obervational one. Cosmological models with varying by time physical constants, namely, speed of light and gravitational constant and/or their combinations, are considered. In one of the models, for example, vacuum energy density induces effective n...

Garcinia lanceifolia Roxb. is an important and endemic medicinal plant of Assam which has been used by various ethnic communities of Northeast India to treat various disorders like dysentery, dyspepsia, and biliousness. The plant is considered to be containing much medicinal value and is also eaten raw or made into pickles by the local people. Our present study has been focused on the evaluatio...

The paper addresses the effect of ionosphere on ELF and lower frequency waves excited in Earthionosphere waveguide by a controlled source. experiment carried out Kola Peninsula is described results measurements range 0.4--95 Hz are presented. Non-monotonic behavior magnetic field with time revealed. It shown that variations related to state depend geomagnetic activity. importance topside struct...

The endothelial cells’ dysfunction linked to the development of atherosclerosis plays an important role in regulation inflammatory responses. Previous studies demonstrated antiatherogenic effects Garcinia kola seed extracts based on their lipid lowering effects. Our recent showed vitro antioxidant and anti-inflammatory activities ethanolic extract stem barks (EE). For more insight effect EE, we...

A detailed chemical study on the stem bark of Garcinia nitida has led to the isolation of five xanthones. They are 1,6-dihydroxy-5-methoxy-6,6-dimethylpyrano[2',3':2,3]-xanthone (1), inophyllin B (2), osajaxanthone (3), 3-isomangostin (4) and rubraxanthone (5). The structures of these compounds were established using mainly 1-D and 2-D NMR spectroscopy ((1)H, (13)C, DEPT, COSY, HMBC and HMQC) w...

Garcinia has some 260 species and is often regarded as a genus with a difficult taxonomy. No recent treatment is available for the botanically rich Lower Guinea phytogeographical region. This study aims at partly filling this gap. First, several taxonomic problems are solved. Garcinia chromocarpa is reduced to a variety of Garcinia quadrifaria. Garcinia gnetoides and Garcinia granulata are both...
