The prolonging effect of Japanese kelp (kombu) on life span was investigated in mice fed a diet containing the carcinogen benzo[a]pyrene (BaP). Three groups of six mice each were fed a normal diet with 0, 2 and 5%, kombu powder, while another three groups were fed those diets with 4 ppm BaP loading. The 2 and 5% kombu diets did not affect life span compared to the control group given 0%, kombu....

Differential cholinergic modulation of Ca transients evoked by backpropagating action potentials in apical and basal dendrites of cortical pyramidal neurons. J Neurophysiol 99: 2833–2843, 2008. First published April 16, 2008; doi:10.1152/jn.00063.2008. The effect of the cholinergic agonist carbachol (CCh) on backpropagatin...

Glycine N-methyltransferase (GNMT) affects genetic stability by (a) regulating the ratio of S-adenosylmethionine to S-adenosylhomocystine and (b) binding to folate. Based on the identification of GNMT as a 4 S polyaromatic hydrocarbon-binding protein, we used liver cancer cell lines that expressed GNMT either transiently or stably in cDNA transfections to analyze the role of GNMT in the benzo(a...

A protocol was developed for callus induction and regeneration in tomato (Lycopersicon esculentum) var. Moneymaker. Hypocotyl and leaf disc explants of tomato were used as a starting material for callus induction. Explants were cultured on MS medium having different concentrations of hormones. Maximum callogenesis from hypocotyls was obtained on MS medium supplemented with IAA (2 mg/l), NAA (2 ...

MPEG-4 Body Animation Parameters (BAPs) are used for animation of MPEG-4 compliant virtual human-like characters. Distributed virtual reality applications and networked games on mobile computers require access to locally stored or streamed compressed BAP data. Existing MPEG-4 BAP compression techniques are inefficient for streaming, or storing, BAP data on mobile computers, because (a) MPEG-4 c...

NMR-based metabolic profiling of polar extracts somatic embryogenic and organogenic cultures the medicinal plant Cymbopogon schoenanthus subsp. proximus were studied. Regeneration through embryogenesis was done on media containing 2,4-D BAP while organogenesis achieved NAA BAP. Fifty-two metabolites identified in calli (EC), (OC), regenerated shoots (ES), (OS). Chemometrics cluster analysis use...

The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA and 2, 4-D (auxins). MS media proved b...
