American Chemical Society's Weekly PressPac -- June 27/July 3, 2007

...lain that LOIS uses a laser beam and ultrasound to detect early-stage cancer. LOIS, they note, has advantages over conventional optical and ultrasound imaging methods in being able to see deep into the body and reveal diseased tissue. Use of LOIS, however, has been limited by lack of a suitable contrast age...

Discovery could help bring down price of DNA sequencing

...e thread going through a needle. The technique can detect individual DNA molecules, but the DNA gallops through so fast that it is impossible to read the individual letters, or bases, and determine the sequence.

Support for chromosomal theory of cancer found in cancers' development of drug resistance

...roscope. "By screening for aneuploidy, you could detect the cancer early and also see what possible drugs to use and whether drugs would even help," Duesberg noted. "Then, you wouldn't have to give a cocktail of drugs that includes all the best poisons, but you could leave out those you could tell wouldn'...

Sentinel lymph node biopsy is associated with breast cancer rates

...d from a tumor. Sentinel lymph node biopsies often detect small numbers of tumor cells that do not necessarily indicate that the cancer has spread. While the use of [sentinel lymph node biopsy] in community practice continues to increase, it is expected that cases with [lymph node] metastases also will co...

...d and analyzed so that an operator can immediately detect changes in the fermentation process. The technology can be automated, runs continuously unattended and can be configured to trigger process controls such as valves and switches. The ultrasound technology is also useful for measuring cell or organis...

Which came first: Primates' ability to see colorful food or see colorful sex?

...them in foraging, specifically by allowing them to detect red/orange food items from green leaf backgrounds. However, the results from several empirical studies have called into question the extent to which trichromacy functions in foraging and if it provides a performance advantage over dichromatic primate...

CU study reveals why starling females cheat

...additional help. As yet, it is unknown how females detect the genetic similarities between themselves and their mates, though other species of birds appear to adopt similar mating strategies. "This is the first study to show that individuals from the same population mate with extra-pair males and gain bot...

Hepatitis B drug can compromise HIV treatment

...ibb using techniques available at the time did not detect such an effect on HIV, said Siliciano. However, Thio, study co-author Robert Hegarty, and Braden Hale of the Naval Medical Center in San Diego recently identified three co-infected patients in whom entecavir treatment did inhibit HIV replication. S...

454 sequencing identifies HIV drug resistance at early stage

...r treatments. The ability to use 454 Sequencing to detect rare viral mutations is a crucial research tool to better understand the early stages of HIV drug resistance. It is estimated that 22 million people have died from AIDS and over 42 million people are living with HIV/AIDS worldwide. In the U.S. alon...

High cholesterol diets modify gene expression in atherosclerosis

...pidly: a 20-day high cholesterol diet is enough to detect atheromatous plaques in their arteries. Experts obtained SMCs from arteries before the formation of the plaques. Ten days after the start of the high cholesterol diet when atheromatous plaques are not still visible using an electron microscopic a...

Study helps preserve Arctic whale, Eskimo subsistence hunt

...w, Alaska, in the spring and fall, researchers did detect an unexpected level of genetic variation but speculate it stems from the whale's unusual age structure, as opposed to unique subpopulations. Bickham said he suspects the high commercial-whaling mortality rates of the 19th and early 20th centuries may...
