anal cytology and behavioral data from 1,262 HIV-negative men ages 18 to 89 in four U.S. cities: Boston, Denver, New York, and San Francisco. The prevalence of low-grade and high-grade precancerous lesions was 15% and 5%, respectively, and did not ch...
Exposure to sunlight may decrease risk of prostate cancer
...f prostate cancer," they said. The scientists also obtained
a sun exposure history from each participant so they could track outdoor activity. "Reduced risk of advanced prostate cancer was associated with high sun exposure determined by reflectometry and high occupational outdoor activity," they said. "Furt...
Silenced gene suggests greater risk, possible marker for African-Americans with prostate cancer

from Shimane University Hospital in Izumo, Japan; all Caucasian and African-American samples were obtained
at SFVAMC. From each sample, the researchers took DNA, amplified it using polymerase chain reaction ...
Self-correcting embryos could be an ethically acceptable source of embryonic stem cells
...1." Good quality, normal embryonic stem cells were obtained
initially from one of the normalised cultures, and more are being developed. So far no stem cells from completely abnormal embryos have been developed. Although the mechanism by which the embryos self-corrected their abnormalities was not clear, Dr M...
New method of obtaining embryonic stem cells could reduce embryo wastage
... line. From a control group of 51 blastocysts, she obtained
nine ESC lines. Dr Takeuchi, also from the Center for Reproductive Medicine and Infertility, told the conference: "This showed that it was possible to isolate and culture blastomeres that were capable of developing into any type of cell, including st...

from the process are at an early stage of development," Dr Lacham-Kaplan said. "Further studies are required to explore whether they're normal and able to mature and participate in fertilisation and embryo development." Dr Lacham-Kaplan's ultimate go...
Imprinting disorders and ART world's largest study results are reassuring
...K who were in support groups for the disorders and obtained
family histories and details of whether or not they had had ART, and if so, which kind. Out of 82 replies from families who had had a child with BWS, 10 had used ART in order to conceive (12%). Families with children with TND, AS, and PWS were al...

were astonishing," Warrick said. They showed that because of the limitations of its wing structure, a hummingbird develops only 25 percent of its weight support during the upstroke, while producing the remaining 75 percent during downstroke. While n...
Study finds parking lot sealcoat may be major source of PAHs
