Exposure to carcinogens not proportionally decreased by reduction in smoking
...so measured the level of the compound anatabine to biochemically verify the patients' self reports of cigarette consumption. Patients were offered nicotine replacement therapy to assist their smoking reduction efforts. Overall, there was a reduction in NNAL and NNAL-Gluc levels at nearly all of the intervals as th...Physicians offer new solution for blood transfusions
... stop. Instead of a blood transfusion, they used a biochemically manufactured solution that contains hemoglobin but does not contain red blood cells. The solution has been used in adults but never for a child in this kind of situation, Kavanagh says. While more study needs to be done with pediatric patients, Kavan...Platelet molecule regulates blood coagulation, study finds
...ggers catalysis and makes sure that prothrombinase biochemically "cuts" prothrombin properly, thereby allowing conversion to an effective thrombin molecule, not a dead-end bi-product. In addition, Lentz and co-authors Drs. Rinku Majumder, Gabriel Weinreb and Xin Zhai suggest that platelet membrane PS can be thoug...Researchers gain insight into function of memory enhancing drugs
...lar and Molecular Neurophysiology, the researchers biochemically isolated one part of the glutamate receptor and determined its structure at the atomic level. They then designed altered, or mutant, receptors and determined their atomic structures as well. By observing how the drugs interacted with both mutant an...Glow-in-the-dark zebrafish helping Jefferson scientists uncover cholesterol genes

... might serve aschemical sensors for large complex, biochemically active substances, or evenspecific microorganisms. But the most exciting prospects revolve around the possibility of actuallyinterfacing a chip with living brain cells.

"They feellike they have the flu," says McGahan. And if the treatment damages nerves nearthe liver's surface, patients may feel chest...... weight and stress. "Menopause is characterized biochemically by high levels of two hormones, luteinizing hormone (LH) and follicle stimulating hormone (FSH) and low levels of estrogen," says Holman. "Amenorrhea is characterized by low levels of LH and FSH but may have normal levels of estrogen." Holman i...
