Extend Cervical Smears to Younger Women, Insist Specialists

... carcinoma in situ ; pre-cancerous tumors that are precursors of cervical cancer. The NHS Cervical Screening Program has reportedly saved thousands of lives, as around 4500 case of cervical cancer are identified per year under this program. According to the scientists , this program of the NHS will be ‘un...

'single–parent' stem cells to replace adult mice organ

...he researchers could then harvest fetal liver cell precursors for transplant. Ultimately, the scientists found that uniparental cells, regardless of parent of origin, were able to functionally replenish the entire blood-producing system of adult mice. The scientists were able to maintain animals for more tha...

Primitive Yeast Yields Secrets Of Human Cholesterol And Drug Metabolism

...t, the altered human cells accumulated cholesterol precursors and died because cholesterol is essential for cell survival. To show that Dap1 directly works with P450s and not through some other biochemical steps, Espenshade’s team tested the ability of human Dap1 protein to bind to four of the 57 known human ...

A New Inexpensive Technology for Multiplexed Detection

...racteristics. As two streams of monomers (liquid precursors loaded with fluorescent dye or molecular probe) flow side by side through a microfluidic device, ultraviolet light repeatedly strikes the streams. A chemical reaction initiated by the light causes the liquid to solidify, forming a single particle wit...

UK to Pull Pseudoephedrine

...it calls the "global problem [of]…the diversion of precursors used in illicit manufacture of methylamphetamine," noting that since the beginning of 2005, 30 cases of attempted diversion have been reported to the board. Source-Bio-Bio Technology SM...

Hot Flashes in Men Treated for Prostate Cancer Reduced by Non-hormonal Drug

...ormones. This class of compounds also includes the precursors to estrogen.) In general, men dont develop hot flashes because their production of steroid hormones gradually tapers off as they age, Dr. Loprinzi says. But the dramatic decrease in testosterone with prostate cancer treatment can cause hot flashes. ...

DNA-damage Test Could Aid Drug Development

...blood cells formed in the bone marrow of mice. The precursors to red blood cells are handy for this because such... last stage of red cell formation, and DNA-damaged precursors generate red blood cells containing an easily detected 'micronucleus' consisting of fragments of nuc...

Saliva Helps to Identify Child Victims of Chronic Bullying

...y as a reliable biomarker for assessing effects of precursors to bullying. This hormone is responsible for regulating various behavioral traits, such as the fight-flight response and immune activity, which are connected to sensory acuity and aspects of learning and memory. 'A lot of kids suffer in silence. W...

Hemangioblasts New Tool Of Stem Cell Technology

...om a cloned human embryo. Embryonic stem cells are precursors to almost every tissue in the body. In the new study, the ACT team reports growing billions of hemangioblasts from eight human embryonic stem cell types. They report using them to treat diabetic rats, as well as damaged blood vessels in mice. ...

Keep a Cool Head on Hot, Humid Days to Avoid Heat Stroke

...erature; and profuse sweating. Any of these can be precursors to a full-blown case of heat stroke. "If you exhibit any of these symptoms," Dr. Heine advises, "get out of the heat, rest, and drink plenty of cool fluids, preferably containing sugar and salt." Heat stroke's symptoms, similar to those mentioned...

Scientists Identify "master Switch" for Brown Fat in Mice

...riments, the researcher inserted PRDM16 genes into precursors of white fat, and implanted the white fat precursors under the skin of the animals. The PRDM16 gene coaxed those cells to generate brown fat cells. "T...

Scientists Identified Obesity Control Switch

...na-Farber investigators inserted PRDM16 genes into precursors of white fat, and implanted the white fat precursors under the skin of the animals. The PRDM16 gene coaxed those cells to generate brown fat cells. "Th...
