Space technology harnessed to search out TB

... diagnosing TB in resource-poor settings relies mainly on the use of smear microscopy of sputum samples, a very labour-intensive process with low ... a GC-MS capable of detecting TB in sputum with greater sensitivity than smear microscopy and significantly quicker than the alternative culture methods. ...

'Normal' cells far from cancer give nanosignals of trouble

... once optimized, could be used to detect cell abnormalities early and help physicians assess who might be at risk for developing cancer. Like a pap smear of the cervix, a simple brushing of cells is all that is needed to get the specimen required for testing. Using PWS, the researchers made another ...

NCI grant launches clinical trials for colon cancer screening

... test are negative in order to correlate the screening results with the colonoscopy results. "Our hope is that similar to how the routine pap smear drastically reduced deaths from cervical cancer, this new technology could do the same when it comes to colon cancer," said Backman. Backman's ...

Squirrels use snake scent

... California ground squirrels and rock squirrels chew up rattlesnake skin and smear it on their fur to mask their scent from predators, according to a new study by researchers at UC Davis. Barbara Clucas, a graduate student in ...

American Chemical Society's Weekly PressPac - Oct. 10, 2007

... per cell a level corresponding to very early infection. The technique, called single-molecule spectroscopy, could be easily integrated into the Pap smear method. It can become a good clinical screening or quantification method for viral DNA in cells, opening the door to improved screening tests for ...

New test for most virulent HPV strains under study

... older and the other is as a triage test when women have an abnormal Pap smear result.? An HPV test typically follows an ASC-US Pap smear which at best, is about 80 percent accurate, he says. However, the ...

Warts vaccine -- 1 of many in pipeline

... the product under trial be effective, it also gives them the chance to be amongst the first to benefit." A vaccine would complement both the pap smear program and currently available vaccines to prevent infections. Genital warts are transmitted by skin contact and the 2003 Australian Study of ...

High HPV concentrations combined with smoking significantly raise risks of cervical cancer

... disease. Gunnell's study, in fact, suggests that both may create a biochemical synergy that propels the disease. The researchers looked at "Pap" smear examination data from 105,760 Swedish women and identified 499 women with cervical cancer in situ, along with 499 cancer-free women as controls. For ...

Higher risk for cervical cancer seen among women infected with multiple HPV types

... HPV types and a woman's risk for developing pre-cancerous abnormalities in her cervix. During each of the 16,000 patient visits, both the pap smear and HPV tests were administered. The mean follow-up time of the study participants was over three years. When Franco, Trottier and their ...

Study of genomic DNA leads to new advances in cancer diagnostics

... cancer? Because the investigators utilized several practical methods in their study, potential exists for future diagnostic applications. The cell smear assay, which is similar to methods commonly used in diagnostics laboratories (such as Pap smears), could be applied to such a purpose. The authors ...
