U-M scientists discover identifying markers for primitive blood-forming stem cells
...0 to 12 of the best classical markers combined. It reduces the skill and time required to pick out a hematopoietic stem cell and makes the process simpler and less labor intensive." "Many of the current markers we use to purify HSCs are expressed as a gradient from high to low across the hematopoietic cell ...Method slashes quantum dot costs by 80 percent
...h the heat-transfer fluid Dowtherm A, for example, reduces the overall materials cost of making quantum dots by about 80 percent. Quantum dots are tiny crystals of semiconducting materials - cadmium selenide or CdSe is the most popular flavor - that measure just a few nanometers in diameter.

This signal essentially puts the plant on alert, but staying on alert too long can be harmful: If not reduced quickly, the toxic superoxide will kil...... an alcohol-based hand sanitizer gel significantly reduces the spread of gastrointestinal infections in the h...first randomized trial to show that hand sanitizer reduces the spread of germs in the home," says Dr. Thomas J.

...of certain key genes gave rise to the archaea that reduces sulfate, but do not make methane. "But it is equally possible that the sulfite reduction system was developed in another organism and the methanogens acquired the sulfite reduction gene via horizontal transfer from that entity," Mukhopadhyay said. ...How Fruitflies Know It's Time for Lunch
...g. Behavioral studies confirmed that too much hug reduces food intake and leads to stunted growth, while too little stimulates eating. Melcher and Pankratz selected a group of flies and blocked the synapses of their hug neurons to inhibit the neurons' activity. In contrast to control flies, which start feed......e, which is shared by the pulling motors, strongly reduces the cargo velocity and leads to a highly nonlinear force-velocity relationship (PNAS, Advanced Online Publication, November 14-18, 2005).

...tal for immunocompromised patients. HAART not only reduces the viral load of HIV, but it also often helps to keep other infections such as TB under control. In fact, previous studies indicate that HAART can reduce the risk of TB in HIV patients by 70 to 90 percent. Although HIV-infected people living in indu...Seal rookeries could provide a reliable food source for endangered California condors, study finds

"Crucially, IMRT reduces the side-effects patients often suffer from radiotherapy and improves accuracy of dose delivery, and these are the most important impacts in the treatment of cancer." ...Access to existing medical treatments could save more lives than spending to improve the treatments
... 100,000 lives a year. If a drug is available that reduces the mortality rate from that disease by 20 percent, it has the potential to save 20,000 lives each year. But if only 60 percent of eligible patients receive the drug, only 12,000 deaths will be averted.

...Research has shown that HIV testing and counseling reduces high-risk sexual behavior and prevents HIV transmission, Thielman said. Testing also gives people access to services such as antiretroviral therapy, treatment for sexually-transmitted diseases and prevention of mother-to-child HIV transmission. ...Newly identified mechanism helps explain why people of African descent are more vulnerable to TB
