Evidence that abnormally short telomeres play a role in the early development of cancer

Scientists at the Johns Hopkins Kimmel Cancer Center say they have evidence that abnormally short telomeres - the end-caps on chromosomes that normally preserve genetic integrity -appear to play a role in the early development of many types of cancer.

Men with low prostate specific antigen levels on screening tests can still have prostate cancer

Men with low PSA (prostate specific antigen) levels on screening tests can still have prostate cancer, according to a study* released today by scientists from the National Cancer Institute (NCI).

Research may lead to elimination of surface-induced thrombus formation

A University of Missouri-Rolla researcher’s investigation into how proteins adhere to surfaces may lead the elimination of surface-induced thrombus formation, a phenomenon known to cause blood clots in artificial arteries, valves and veins.

Cultured nanoparticles from filtered homogenates of diseased calcified human cardiovascular tissue

Researchers at the Mayo Clinic found they could isolate and culture nanoparticles from filtered homogenates of diseased calcified human cardiovascular tissue. These cultured nano-sized particles were recognized by a DNA-specific dye, incorporated radiolabeled uridine, and after decalcification, appeared via electron microscopy to contain cell walls.

Scientists may have figured out how to use stem cells to regenerate lost or injured tissue

In experiments with fruit flies, Johns Hopkins scientists have restored the insect's sperm-making stem cells by triggering cells on the way to becoming sperm to reverse course. The unexpected findings are described in the May 13 issue of Science.

Multimillion-dollar electron microscope unveils shapes of viruses and proteins

With a multimillion-dollar electron microscope and computer programs that can pick out the shapes of structures only six atoms wide, Dr. Wah Chiu and his colleagues at Baylor College of Medicine in Houston are attempting to explain the intricate structures of viruses and proteins.

Technique to visualize changes in nerve connections when flies learn may help to understand how memories form

For the first time, researchers have used a technique called optical imaging to visualize changes in nerve connections when flies learn. These changes may be the beginning of a complex chain of events that leads to formation of lasting memories.

WHO reports on treating tuberculosis in Ukraine

Multidrug-resistant TB (MDR-TB) is the disease caused by TB bacilli that are resistant to at least isoniazid and rifampicin – the two most powerful anti-TB drugs. It results from inconsistent or partial treatment of TB, and develops when public health programmes fail to deliver regular and reliable treatment to TB patients.

Telemedicine focus of symposium "Future Directions for Telemedicine"

A pediatric patient in Marquette, Michigan is being examined by a doctor— but the doctor is 365 miles away in Ann Arbor. Elsewhere in Michigan, a mental health patient, his family and psychiatrist are participating in a commitment hearing in the safe, secure environment of a psychiatric unit— but the judge is actually on the other side of town.

Overview of West Nile virus before season starts

West Nile virus is a newly emergent virus of the family Flaviviridae, found in both tropical and temperate regions. It mainly infects birds, but is also the cause of a number of conditions in humans, horses, and some other mammals. It is transmitted by bites of infected mosquitoes.

Scientist discovers why skin turns leathery

“The reason our skin becomes more leathery and thick as we age might be due to a loss of elasticity in the cells,” says Igor Sokolov of Clarkson University, who presented his latest research findings during a session on bio-imaging techniques at the Annual American Physical Society (APS) March meeting in Montreal.

Using mass spectrometry to diagnose cancers and non-cancerous diseases

Using mass spectrometry, Emory University scientists have identified specific protein fingerprints in the cerebrospinal fluid (CSF) of humans that enable them to differentiate between cancers, both primary and metastatic, and non-cancerous diseases of the central nervous system (CNS).
