Lycopene slows human prostate tumour growth in mice and combined with vitamin E is even better

..., one low and one high dose of synthetic vitamin E alone and a combination of low dose synthetic lycopene and vitamin E or a placebo. The researchers injected human tumour cells into the prostate of mice to see what effect the lycopene and vitamin supplements would have on the tumour growth and PSA (prosta...

Unicellular organisms contribute more nitrogen to ocean that reported earlier

Embryonic stem cell therapy shows steady benefits in rebuilding infarcted heart

...schemic heart and related cerebrovascular diseases alone caused an estimated 17 million or 23.2% of deaths globally in 2000, WHO reported. A contributing cause of what some have called a pandemic is that in contrast to many other organs in the body, the heart has only a minimal capability for self-renewa...

Hopkins scientists use blood proteins to detect ovarian cancer

...andards. The new test plus CA125 as well as CA125 alone detected 83 percent (19 of 23) of the cancers. In addition, the new test plus CA125 correctly identified healthy samples 94 percent of the time (59 of 63) as compared to 52 percent (33 of 63) for CA125 alone. To verify that the candidate markers wer...

Alcohol-use and depression among pregnant and postpartum women

Future research may also target treatment strategies that address both these issues, instead of treating them separately and in isolation from each other. They may be causally linked. That is, women may en...

Protective gene may enhance vaccine responses

...," Ashton-Rickardt said. "Increasing Spi2A levels alone can increase the survival of memory T cells from the standard 5 to 10 percent up to about 40 percent. His lab has already begun to test small molecules that mimic the effects of Spi2A and could be given along with a vaccine. This finding may also...

Marijuana ingredient inhibits VEGF pathway required for brain tumor blood vessels

However, the main tumor often evades total destruction, surviving and growing again, eventually killing the patient. For this reason, researchers are actively seeking other therapeutic strategies, some of which mi...

Activated signaling pathway may predict lung cancer patients' response to gefitinib

...ier studies have found that the expression of EGFR alone does not predict whether a patient will respond to gefitinib, there are many signaling pathways that are dependent on EGFR expression. To determine whether two such pathways--called Akt and MAPK--may be involved in a patient's response to gefitinib,...

Save the rainforest - eat a tree

"But we showed that if it wasn't for their insect enemies, it's possible the same kind of plants would grow on both soil types. The inse...

Epilepsy: Signals 'brake' in brain impaired

...bilities. Epilepsy is a common disease: in Germany alone there are 600,000 people whose nerve cells in the brain occasionally switch from healthy chaos to common mode. The result of the uncontrolled mass discharge of neurons is loss of consciousness and spastic convulsions of the muscles, during which thos...

Casanova or caveman: Scientists isolate nerve cells that choreograph male fly's courtship behavior

Scientists suggest framework for epigenetics in common disease
