New compound protects against liver cancer

...nt led to an 85 percent reduction in pre-cancerous lesions at the lowest dose of 50 micrograms per rat and a 99 percent reduction at the highest dose of 5 milligrams. Like other compounds derived from oleanolic acid, CDDO-Im also has strong anti-inflammatory properties, which the researchers say makes it id...

Attention shoppers: Researchers find neurons that encode the value of different goods

... Previous work in other laboratories showed that lesions to the OFC can result in choice deficits such as eating disorders, compulsive gambling, and abnormal social behavior. Moreover, the OFC is part of brain circuitry implicated in drug abuse, which can also be thought of as a choice deficit. Padoa-Schio...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

Making medicine 'smarter'

... to the improved diagnosis of indeterminate breast lesions by non-invasive imaging," Meyer-Baese said. "We will deliver a flexible and reusable software system in MR mammography." Meyer-Baese said she was "thrilled" to hear that she had been chosen for an NIH Career Award. "I was very excited, because I ca...

Prostate cancer uses Wnt signaling proteins to promote growth of bone tumors

...ekeeping in bone tissue and produce the dense bony lesions characteristic of prostate cancer. Now, new research by scientists at the University of Michigan's Comprehensive Cancer Center suggests that prostate cancer manipulates an important group of signaling proteins called Wnts (pronounced "wints") to est...

Building a better mouse model of lung cancer: FHIT counts

...rowth are released, allowing potentially cancerous lesions to become malignant. Studies show that very early in the development of lung cancer, the FHIT gene loses its ability to produce a specific protein (called Fhit). This same loss has been linked to head and neck, esophageal, colorectal, breast and cer...

Study hints at role of stem cell genes in testicular, breast cancers

... capacity of cells to specialize, causes dysplatic lesions in the intestines, skin and stomach. "It would be useful to look at NANOG in those places where we know over expression of OCT 4 results in tumor progression," she says. "It may be playing a role there, too." Other co-authors of the study were Uche ...

Vaccine targets tumors where they live

...to established melanoma lesions. 2 of the injected lesions showed a partial response and 3 were stable. One patient remained alive without disease recurrence for 59 months after vaccination without any other therapy. This approach may be useful for altering the tumor environment in order to induce anti-tumor...

How cell suicide protects plants from infection

...er of cells that later die and form discrete brown lesions on the leaves. When the gene is inactivated, the plant can no longer regulate PCD, leading to cell death throughout the leaf and plant. PCD has been described in virtually all cell types, both plant and animal. It is an important aspect of many biol...

A probe, not an echo

...t should allow clinicians to distinguish malignant lesions from benign growths in a non-invasive and highly r.... This promises to allow non-invasive detection of lesions in clinical diagnosis, which represents the "holy grail" of medical imaging. The team found it poss...

Scientists identify genes responsible for 'black rot' disease in vegetables

...heir leaves yellow and black, and causing V-shaped lesions along the margins of the leaves. All vegetables in the crucifer family, including broccoli, Brussels sprouts, cabbage, cauliflower, kale, mustard, radish, rutabaga, and turnip, are potential hosts for Xcc. The model plant Arabidopsis thaliana is also...

Master gene controls healing of skin in fruit flies and mammals

... in the healing of insect cuticle when she noticed lesions in the cuticle of certain fruit fly mutants. She suspected that the lesions were scar tissue resulting from the failure of the body surface barrier to develop properly. Confirm...

Brain May Be Less Plastic Than Hoped

...pret,?he said. “But in the macaque, you can design lesions and test pharmaceuticals to sort out what kind of reorganization the brain is capable of after, say, a stroke. It's a powerful way to stimulate and study reorganization that may turn out to be beneficial in the future.?/p>...

Grasping metaphors: UC San Diego research ties brain area to figures of speech

...-matched control subjects, on the other hand, with lesions in other areas of the brain, performed normally both with proverbs and the booba/kiki test. Disproportionately larger in hominids than other primates, the angular gyrus, given its strategic location at the crossroads of areas specialized for process...

Brain-injury rehabilitation depends on acetylcholine circuitry

...rchers then used electrical probes to create small lesions in the rats' brain region responsible for controlling limb movement. They then gave the rats rehabilitation training. The control group of rats recovered about 55% of the deficit in their reaching ability, while the rats lacking a cholinergic system...

Pulsating ultrasound enhances gene therapy for tumors

...asers and electric current, are limited to surface lesions or require needles to be inserted in the body. Pulsed-HIFU is non-invasive and can treat any area of the body accessible by ultrasound, the exceptions being the lungs and bones. Additional advantages of pulsed-HIFU include no scarring, limited blood ...
