Tinnitus :: Low-pitch treatment alleviates ringing sound of tinnitus
For those who pumped up the volume one too many times, UC Irvine researchers may have found a treatment for the hearing damage loud music can cause.

DNA :: Disposable sensor uses DNA to detect hazardous uranium ions
Researchers at the University of Illinois at Urbana-Champaign have developed a simple, disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments.
Breast Cancer :: Gene expression test reveals ER and HER-2 status of breast tumors
Two critical characteristics of breast cancer that are important to treatment can be identified by measuring gene expression in the tumor, a research team led by scientists at the University of Texas M. D. Anderson Cancer Center reports in Lancet Oncology online.
Leukemia :: First antisense drug provides benefit to subset of chronic lymphocytic leukemia patients
The first “antisense” drug to be tested in chronic lymphocytic leukemia (CLL) shows benefit in a phase III clinical trial for a specific subset of patients – those who are still sensitive to a chemotherapy drug often used to treat this cancer.
Liver :: Liver an excellent target for cancer gene therapy using viral vectors
A featured paper in the Feb. 14 issue of Nature Cancer Gene Therapy demonstrates that cancer cells in the liver are excellent targets for gene therapy using adenoviral vectors, based upon a fundamental new understanding of the differences between cancerous and normal liver cells. The findings signal a new way to treat cancers that have spread to the liver, such as metastatic cancers of the colon and breast.
Heart Disease :: Living in poor neighborhoods raises risks for heart disease and stroke
According to a new study from the Stanford University School of Medicine, the incidence of heart disease and associated fatalities are higher for people who live in poor neighborhoods verses those who live in more affluent areas.
Diabetes :: Study of diabetes and race reveals the imperfect science of defining ethnic groups
While previous biomedical research studies have found that genetics and race increase risk for some diseases, a new look into how researchers study genetic triggers of type 2 diabetes suggests that defining race remains an inexact science, with social and historic facts mixing with biology throughout the research process.
Heart :: Call made for changes in women’s heart disease risk-factor list
Johns Hopkins cardiologists are calling for an expansion of the criteria widely used by physicians to detect and assess a postmenopausal woman’s chances of developing cardiovascular disease, the leading cause of death among women in the United States.
Fertility :: Plastics in common household items may cause fertility defects
The contaminant bisphenol-A (BPA) — widely used to make many plastics found in food storage containers and dental products — can have long-term effects in female development, according to a recent study by Yale School of Medicine researchers.
DNA :: DNA Ends – Common Tool, Different Job
Every time a cell repairs or replicates its DNA, the resulting single strand is wrapped up by a dedicated protein complex. In eukaryotes or organisms whose cells have a nucleus, this job is handled by a tripartite complex called replication protein A (RPA).
