Researchers uncover new mechanism of tumor suppressor

... effects, will appear in two reports in the May 21 advanced online version of the journal Nature. The studies, led by Tatiana Kutateladze, PhD, an assistant professor in the UCDHSC Department of Pharmacology, and Or Gozani, MD, PhD, an assistant professor in the Department of Biological Sciences at Stanford ...

The molecular mechanism of a diabetes vaccine revealed

...ffectiveness of the vaccine, which is currently in advanced stages of clinical trials. Type 1 diabetes is an autoimmune disorder in which the immune system mistakenly attacks the body's own insulin-producing pancreatic cells, reducing and ultimately eliminating the production of insulin ?a hormone needed to c...

Virtual realities against pain

...te with the signals of the harmful stimuli. The advanced distraction techniques (ADTs) recently developed use 3D images combined with dynamic audio stimuli, making the techniques more likely to meet the requirements of an ideal distractor than the traditional distraction methods such as watching a film or ...

NASA technology helping injured US troops

...es and modified the cable-compliant system into an advanced walker with a flexible harness that embraces the lower torso. "We felt SAM would be an ideal fit for Walter Reed because it makes the rehabilitation process less taxing on both the patient and the medical staff," said Enduro's president Ken Messier. ...

First 'encyclopedia' of nuclear receptors reveals organisms' focus on sex, food

...e poster will be a tool for researchers engaged in advanced investigation of the biological role of each receptor individually and as a superfamily. The paper and poster also are available online as part of the Nuclear Receptor Signaling Atlas ( www.NURSA.org ), a consortium of scientists working in the field...

Researchers add crucial information on how the body's T cells react to parasitic diseases

Everything in its place: Researchers identify brain cells used to categorize images

... where such memories are found. They report in the advanced online Nature that they have identified neurons that assist in categorizing visual stimuli. They found that the activity of neurons in a part of the brain called the parietal cortex encode the category, or meaning, of familiar visual images and that ...

Malignant melanoma cells secrete protein required for embryo formation

...escribing this research was published today in the advanced online issue of the journal Nature Medicine. The researchers identified the potent and highly unstable embryonic growth factor by injecting aggressive melanoma cells into developing zebrafish embryos, which were used as "biosensors" for tumor cell-de...

Epidemic of unneeded amputations

...ths, respectively, after the first amputation. In advanced stages of peripheral vascular disease (PVD), common in diabetics, plaque blocks arteries, resulting in rest pain, development of foot ulcers and onset of limb loss. The CLiRpath procedure, using a "cool" excimer laser and catheter system developed by...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

... has been in use for generations. But particularly advanced and powerful multi-photon microscopes using infrared beams to image fluorescent cells in living tissues became commercially available in the late 1990s. That prompted von Andrian to embark on a project to use the technology to study the immune syste...

Anti-inflammatory drug's potentially deadly side effect found to be rare

... speech disturbances, loss of coordination and, in advanced phases, paralysis and coma. "It leaves the brain short-circuited," Clifford says. "It's a very bad disease that normally progresses to death within a few months unless we can reverse the immune suppression." MS is an autoimmune disease believed to...

In earlier research, Belcher and colleagues learned they could exploit the abilities of microbes to recognize the correct molecules and assemble them where they belong. A new means of inducing this order comes from self-ass...

Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

However, according to Farrell, these current agents have limited activity against many common human cancers, and they are susceptible to acquired drug resistance. He ...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

...lleagues found in an examination of 85 dancers and advanced dancing students in Israel variants of two genes that provide the code for the serotonin transporter and arginine vasopressin receptor 1a. Both genes are involved in the transmission of information between nerve cells. The serotonin transporter reg...

Aging cells, aging body: Fresh evidence for a connection

...tive senescence. The new research, published in an advanced online edition of Science, is the first to quantify the presence of replicatively senescent cells in any species. "For 40 years, we've known about replicative senescence," said John Sedivy, a Brown professor of medical science and the senior scienti...
