Adding Radiation Therapy To Chemotherapy Improves Survival In Patients With High-risk Breast Cancer

...on therapy in breast cancer patients and note that fewer clinicians accept its use in moderate-risk patients. "Because uncertainties continue about the effectiveness of locoregional radiation therapy after mastectomy in moderate-risk patients, we strongly urge that a randomized controlled trial be mounted ...

Novel Asthma Study Shows Multiple Genetic Input Required; Single-gene Solution Shot Down

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...treat that primary tumor at lower doses, too, with fewer side effects for the patient," Dr. Huang said. Until now, agents that specifically target metastatic cells have remained elusive. However, a new avenue of research opened up when Dr. Huang's team noticed that the Streptomyces bacterium -- the bug th...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...ong deficiency of growth hormone had substantially fewer tumors ?63 percent ?and the percent of tumors that were fatal was reduced from 57 percent to 31 percent. The same pattern occurred for kidney disease, which was found in 74 percent of the normal male animals at the time of their deaths. None of the ...

Circles Of DNA Might Help Predict Success Of Stem Cell Transplantation

...ransplantation were more likely than patients with fewer copies to experience successful reconstitutions of their T cell populations. In patients with fewer than 1,200 copies per milliliter, the transplantation was likely either to fail or be significantly ...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...e effectively treat diseases while also generating fewer side-effects. "We're basically now able to open the hood of yeast, worm, and fly cells and look at the protein interactions inside," said Trey Ideker, a bioengineering professor at the University of California, San Diego and one of the nine co-autho...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

... genes we have in our genome—more than a fruitfly, fewer than a rice plant—a more fundamental genetic truth... the genome. Instead, they are bunched together in fewer than 200 clusters, most of them in close proximity to genes implicated in transcriptional regulation...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...ction of the time of traditional chemotherapy with fewer side effects caused tumors to shrink in 95 percent of patients, a new study by researchers at the University of Michigan Comprehensive Cancer Center found. Patients with advanced-stage follicular lymphoma ?a cancer generally considered incurable ?wh...

Antibiotic might fight HIV-induced neurological problems

...ressive, so we can get meaningful data by studying fewer animals," says Zink, who was on the team that developed the model about six years ago. "It's a really demanding test of a potential treatment for HIV." The animal model has already helped improve understanding of how HIV might affect the brain, and ...

Artifical cornea lets woman blind 20 years see

...al blindness is a major problem due to infections, fewer physicians and problems with hygiene," says Afshari. The major hurdle right now, according to Dohlman, is the cost of the procedure. "The healthcare system in poor countries cannot afford such devices right now, but in a few decades that situation m...

Genetically modified rice in China benefits farmers' health, study finds

Results of the study will appear in the April 29 issue of the journal Science. "This paper studies tw...

Use of Insecticides Linked to Lasting Neurological Problems for Farmers

...ical symptoms compared to those using insecticides fewer than 50 days. The researchers found no significant association between neurological symptoms and other chemicals, including herbicides or fungicides, and only a weak association between fumigant exposure and neurological symptoms. Some of the insect...

Surprising findings reported about iron overload

... study found that primary care physicians provided fewer than 70 percent correct responses about screening at-risk populations for hemochromatosis, iron overload, and associated abnormalities. As the HEIRS Study shows, iron overload was mistakenly believed to be a disorder that is limited to Caucasians, s...

Variation in women's X chromosomes may explain differences among individuals, between sexes

...ver evolutionary time, leaving the chromosome with fewer than 100 functional genes. In contrast, the X chromosome -- present in at least one copy in both sexes -- encodes more than 1,000. More than 45 years ago, researchers discovered that genes on one copy of the female's X chromosome are switched off, a...

Polymers with copper show promise for implanted sensors

... an improvement in the accuracy of the sensors and fewer clots on the sensor surfaces when we use nitric oxide-releasing polymeric coatings," said Meyerhoff. However, those materials have some characteristics that may limit their usefulness. "In some instances, the chemistry in the polymer is sensitive to...

A human parasite with a streamlined mitochondrion

...oeba mitosome means that it must be able to do far fewer jobs than our own mitochondria. Further experiments performed by the team reveal that the Entamoeba carrier can only transport ADP and ATP, suggesting that it could fuel energy-requiring reactions within the mitosome but might not perform other funct...

New winter hulless barley has high protein

For example, producers would obtain higher yields of a safer and higher quality grain that is resistant to Fusarium head blight, commonly referred to as scab. Scab problems have occurred on an annual basis during the past decade, and...

Multi-purpose protein regulates new protein synthesis and immune cell development

Zhang transplanted hematopoietic stem cells from IRE1 knock-out embryos into mice whose bone marrow had been destroyed by ...
