River Blindness Becoming Drug Resistant

... worms that cause river blindness. Ivermectin only acts to kill young worms, so any adult worms in patients would still be present, even after treatment. In four of the 10 communities, people were shown carrying a higher number of immature worms - the opposite result expected from the drug - suggesting ...

Research Studies on Molecular Switches of Gene

...genes in response to a molecule called cAMP, which acts as a messenger for a variety of stimuli including hormones and nerve-signaling molecules called neurotransmitters. The St. Jude team showed that each gene that responds to CREB chooses which co-factors, or helper molecules, CREB uses to activate th...

Fishes Use Threat of Punishment in Mating Process

... have shown the threat of expulsion from the group acts as a powerful deterrent to keep subordinate fish from challenging those more dominant than themselves. In fact the subordinate fish deliberately diet - or starve themselves - in order to remain smaller than their superiors and so present no threat ...

British Scientists Discover New Protein to Treat Epilepsy and Schizophrenia

... protein that could do the trick. The SUMO protein acts to damp down the amount of information transmitted to cells. And so boosting the level of the protein in the brain could the key to tackling diseases such as epilepsy and schizophrenia, the Bristol scientists think. There are 100 million nerve ce...

Slowing the Racing Heart

...May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline. A single cell in the upper right chamber is responsible for setting the pace of the beating heart, triggering its neighbor cells to beat. In...

Making Change: The Cost of Being Transgender

...ransgender people also must regularly contend with acts of violence. The young people interviewed by ABCNEWS.com all said they had been verbally harassed and some had been physically assaulted. "For the last decade or two, about one trans person is murdered every month," said Mara Keisling, the executiv...

Now a Green Agenda for Mental Health

... (NE), or dopamine (DA). Specifically, serotonin acts as a chemical messenger in the brain. Its job is to pass signals from one nerve ending to the next. Once it delivers its signal or message, serotonin is taken up by the nerve tissue and broken down for the brain and body to reuse. If serotonin levels...

Researchers Identify Immune Dysfunction in Melanoma Patients

...in response to interferon. "Interferon normally acts as a critical signal in activating immune cells," said Critchley-Thorne. Without the ability to respond to interferon, those cells might detect the cancer but won't activate properly. This type of experiment only shows that certain genes are turned...

Tony Abbott Confident Of Australias Vote For Performance Not Promise

... sickness to promoting wellness also and yet Labor acts as if they have just discovered this, well where have they been for the last few years?" On the other side of the fence, Ms Roxon says Mr. Abbott is concentrating his attack on individuals instead of being accountable for his own policies. "It's ...

Lipoic Acid may Help to Live Long, Free of Degenerative Disease

...tion compound, to those of a young animal. It also acts as a strong anti-inflammatory agent, which is relevant to many degenerative diseases," he added. The researchers say that lipoic acid seems to be one of the most promising micronutrients that may be implicated in the ageing or degenerative disease...

Anti-inflammatory Drugs Interact With Hormone Replacement Therapy

...s a role in preventing blood clotting. As estrogen acts to increase production of prostacyclin; it is possible that the effect of hormone replacement therapy on the heart is counteracted by these NSAIDs. The authors conclude that these observations, based on small numbers, are provocative rather than co...

Using Drugs as Weapons can Never Be 'non Lethal', Say Doctors

...rol the amount of a drug delivered or to ensure it acts without producing toxic effects or causing death. It is disingenuous of governments to describe drugs as non-lethal there is no difference between a drug and a poison except the dose. Using drugs as a method of law enforcement may constitute a vio...

Emory Participates in Study to Slow Progression of Parkinson's Disease

...t motor symptoms, says Dr. Juncos. Creatine also acts as an antioxidant to prevent damage from compounds that are harmful to cells in the brain. In mouse model studies of PD, creatine was able to prevent the loss of the dopamine cells in the brain, the same cells that are also affected in PD. "This st...

Mutant Parasites, Unable to Infect Hosts, Highlight Virulence Genes

...om one mutant, Knoll's team pinpointed a gene that acts as a nuclear traffic cop, directing molecular traffic in and out of the parasite's nucleus, where the DNA resides. Mutations in the gene, called RCC1 (Regulator of Chromosome Condensation 1), disrupt the flow of molecules, causing a trafficking break...

New Findings in Fragile X Mental Retardation Protein

...raction. We found that FMRP, together with NXF2, acts to down-regulate the expression of its target, the messenger RNA that encodes NXF1, which is an essential protein needed to transport most mRNAs from the nucleus to the cytoplasm of cells, said Huang. Our findings explain why the NXF1 protein level i...
