Men and women drinking equal amounts of alcohol have unequal risks for liver damage

...in male rats were also regulated by androgens (the generic term for the predominating male hormone) While in female rats, genes affected by alcohol were also changed by the female hormone, estrogen. Other genes changed in both genders but in opposite ways. For example, expression of several genes coding fo...

Ritalin may cause long-lasting changes in brain-cell function, UB researchers find

...falo have shown that the drug methylphenidate, the generic form of Ritalin, which physicians have considered to have only short-term effects, appears to initiate changes in brain function that remain after the therapeutic effects have dissipated. The changes appear to be similar to those that occur with oth...

...irds of the yeast genome. And we were looking at a generic sort of yeast cell; as the cell goes through particular parts of its life-cycle, or experiences dramatic environmental changes, it undoubtedly makes use of different machines. Additionally, some machines are probably put together and taken apart so ...

DNA arrays give clues to better vaccines

.... While the activation program seemed to trigger a generic alarm, which called on other antibacterial defenses of the immune system, the majority of changes triggered in the macrophage involved cell surface proteins and signaling molecules. Such changes generate new functions in the macrophage, suggesting a ...

Sounding the alarm for infections: EMBL researchers discover rapid-response, interferon-producing cells

...e response. Whereas interferon acts as a sort of a generic weapon that will attack nearly any type of virus, the body has a backup system recognizing antigens, the unique molecular fingerprints of pathogens like viruses and bacteria. Dendritic cells acquire these unique markers, activate immune cells, and th...

Experimental therapy stops allergic reactions in mice

...g molecule. As it is constructed now, GE2 contains generic active parts that indiscriminately block reactions to any allergen, Dr. Saxon says. However, a fusion protein like GE2 could be designed to contain a specific allergen such as a peanut protein and thereby block only allergic reactions to peanut. Th...

University of Louisville leads project to customize ethics training for genetic researchers

...ey. However, most such training available today is generic and does not relate directly to a scientists particular area, Rothstein said. The goal of EDGE is to develop a training program that will allow genetic researchers to apply ethical training directly to their area of work. As a first step, the project...

Research into rare disease leads to discovery of six new breast cancer-susceptibility genes

... be more effective than therapies that take a more generic approach. The discovery of the new cancer-susceptibility genes grew out of more than 10 years of research by D'Andrea into Fanconi anemia, a condition known to affect only 500 families in the United States. Children born with the condition usually d...

Scientists identify 'genetic signature' of stem cells

.... "We wanted to know if there is such a thing as a generic stem cell molecular signature," said Lemischka. "In large part, we think there is, and that is what this paper shows." The other paper, published Sept. 11 in the online edition of the Proceedings of the National Academy of Sciences, focused on the ce...

Genes, neurons, and the Internet found to have some identical organizing principles

...nd genetic systems could be classified in the same generic category if they have many motifs in common). This would function as more than just an organizing principle: "One might be able to learn about the neural system by studying the genetic system, which is usually more accessible," says Alon. The team s...

Better understanding of proteins involved in the initiation and control of inflammation could help scientists find...

Researchers determine fundamental mechanisms involved in immune response

...plain the genetic line dance by which an otherwise generic immunoglobulin (Ig), or antibody, molecule acquires the genetic components that encode for the structural characteristics it needs to activate appropriate pathways to eliminate specific types of invaders, or antigens. The appropriate class of Ig can ...

Technique brings immune-based therapies closer to reality

...in Germany. Both aAPCs and dendritic cells convert generic immune cells in the blood into targeted CTLs. The aAPCs were made using a protein called HLA-Ig, which in 1998 Schneck showed could mimic the antigen-waving ability of dendritic cells. In the latest research, Oelke turned tiny magnetic beads into a...
