Lupus Research Institute increases funding for innovative research

... the kidneys, heart, lungs, brain, blood and skin spurs the LRI to reach out to such specialties as cardiology, nephrology, neurology and dermatology and to urge investigators in these areas to bring their best thinking to lupus. This scientific strategy, endorsed by leading immunologists and rheumatologi...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

... brain markers of the immune response. Because it spurs an immune response without live bacteria, LPS helps to reveal how the immune system works on its own, without the complication of side effects. The team found that E. coli-infected pups later injected with LPS had significantly lower concentrations o...

Brain region learns to anticipate risk, provides early warnings. suggests new study in Science

...on a subconscious level." Computer model of brain spurs new discoveries In addition to its findings, the study is significant within scientific circles because of its use of sophisticated computer models to accurately predict the patterns of brain activation that would be sparked by the experiment, patt...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...the level of MYC expression. Excess MYC expression spurs the cells to proliferate. This abnormal behavior then triggers p53 to instruct these overzealous cells to undergo apoptosis. However, such rogue cells can still become fully cancerous if they succeed in eliminating p53 activity, in effect silencing ...

In a randomized, double-blinded human clinical trial, Kenneth Pace of the University of Toronto ( Kenneth.pace@utoronto.ca ) discovered that breaking up kidney stones was more effectively achieved by ad...

Scientists identify novel gene driving the growth and survival of melanoma cells

...cytes. It appears the extra dosage of MITF protein spurs the melanocytes into malignant growth and maintains the tumor's survival. "We might be able to treat these metastatic melanomas by targeting the MITF gene or protein, alone or in combination with drugs that block BRAF," says Sellers. "We know that wh...

Beyond genes: Lipid helps cell wall protein fold into proper shape

...holesterol cousins, include a phosphate group that spurs them to form a bilayer with water-friendly outer layers sandwiching an impermeable water-unfriendly inner layer that defines the outer surface of cells. Transport of nutrients and waste material across the cell membrane is then governed by the specif...

Two designer drugs hit same lung cancer target, but only one is effective

...the overexpressed, or overactive, EGFR signal that spurs growth in several types of cancer. In some forms of the disease, including lung cancer of the non-small-cell type, and colorectal cancer, the abnormal signals are generated by a normal EGFR molecule. In a small percentage of patients with non-small-c...

Lupus Research Institute awards $4.5 million to advance new science in lupus

...hers in many specialties, Shlomchik added, the LRI spurs novel approaches and collaborations not previously applied to lupus. A remarkable number--nearly half--of the 2005 grant recipients are bringing their scientific talents to the study of lupus for the first time. A Proven Formula for Success "The LR...

It's not just teaching them about fish anatomy or physiology, it's teaching them about magnetic resonance imaging, computation and visualization." Education modules within the Digital Dis...

Equivalent of 2-4 drinks daily fuels blood vessel growth, encourages cancer tumors in mice

...st-ever mammalian model of how alcohol consumption spurs tumor growth, showing that even moderate drinking resulted in larger and more robust tumors. The research provides the first mammalian model of the links between alcohol, VEGF, and tumor growth, said Wei Tan, the study's lead author. The study increa...

Plague agent helps UT Southwestern researchers find novel signaling system in cells

...er enzyme, a process called phosphorylation, which spurs that enzyme to add a phosphate group to yet another enzyme, and so on. These "cascading" events trigger an appropriate immune response. Yersinia, however, has the ability to prevent its host from mounting the response, enabling the bacteria to surviv...

UAB researchers find two surgical interventions for preemies have same effectiveness

However, therapeutic strategies for direct interference with the invasion process are lacking. In a study appearing in the June issue o...

Scientists aim to thwart use of flu as bioweapon

Doherty's technical talk on the roles of specific types of T-cells in influenza will be at 1:30 p.m. Friday, June 23, at the Rochester Marriott Airport Hotel on West Ridge Road. The lecture is...

Drug combo may reduce protease inhibitor-related hardening of the arteries

...t infections by consuming unwanted materials. CD36 spurs macrophages to eat cholesterol: The more CD36 the body produces, the more cholesterol the macrophages consume. The problem occurs when cholesterol-laden macrophages get stuck in artery walls. Over time, they accumulate, block the arteries and can r...

Scientists identify switch for brain's natural anti-oxidant defense

...pts the cell to produce more PGC-1a, which in turn spurs the anti-oxidant defenses into action. "With this mechanism, the body can speed up mitochondrial formation and at the same time suppress the creation of reactive oxygen species, which are known to be terribly damaging to the cell," explains Spiegelm...
