pH News and Research

RSS

pH comes from the term “power of Hydrogen”, or the hydrogen ion concentration present in a given solution. It helps to measure the acidity or alkalinity of a substance.

Variation in gene caspase-8 may help protect against breast cancer

A large-scale analysis of data on breast cancer risk has concluded that a common variation in the gene caspase-8 (CASP8) is associated with a somewhat lower risk of the disease. Variants are small changes that occur in a gene sequence.

Vitamin D 'tops' for cancer prevention

Two new vitamin D studies using a sophisticated form of analysis called meta-analysis, in which data from multiple reports is combined, have revealed new prescriptions for possibly preventing up to half of the cases of breast cancer and two-thirds of the cases of colorectal cancer in the United States.

Heat and pH-sensitive nanoparticles target tumors

Using a novel polymer that becomes unstable under the pH conditions inside tumor cells, investigators at Singapore's Institute of Bioengineering and Nanotechnology have developed a core-shell nanoparticle targeted to deliver drugs to tumors.

Virtual human metabolic network for medical science

Bioengineering researchers at UC San Diego have painstakingly assembled a virtual human metabolic network that will give researchers a new way to hunt for better treatments for hundreds of human metabolic disorders, from diabetes to high levels of cholesterol in the blood.

Food can have an impact in preventing cancer

With cancer, researchers don't believe "you are what you eat"; that disease is always a direct result of what is, or what isn't, on your dinner plate.

A single dose of doxorubicin-functionalized bow-tie dendrimer cures mice bearing C-26 colon carcinomas

In a dramatic demonstration of the power of nanotechnology, a team of investigators has designed a nanoscale, polymeric drug delivery vehicle that when loaded with a widely used anticancer agent cures colon cancer in mice with a single dose.

Self-assembling nanoparticle releases drug into cell cytoplasm

A growing body of research leaves no doubt that nanoparticles can transport drugs into cancer cells, but what is less clear is that the drug payload can exit the tiny endosomes that pull nanoparticles into cells.

Teenage birth rate in Alabama continues to decline

The number of births among teenage girls in Alabama declined in 2005 from the previous year, continuing a downward trend in the teen pregnancy rate over the last 10 years, according to a new report from the Alabama Department of Public Health's Center for Health Statistics, the Birmingham News reports.

Smart nanoscale bioreactors for drug delivery

In a powerful demonstration of how to build a multifunctional, smart nanoscale drug delivery system, researchers at the University of Basel have created a drug-loaded nanocontainer that targets specific cells and releases its payload when receiving a specific physiological signal.

Televised movie trailers expose youth to images of tobacco use

Despite a ban on tobacco advertising on television, nearly all U.S. children age 12 to 17 years may have been exposed to tobacco use through movie advertisements televised in 2001 to 2002, according to an article in the September issue of Archives of Pediatrics & Adolescent Medicine.

How the body controls brain temperature: the temperature shielding effect of cerebral blood flow

Attempts to cool the brain to reduce injury from stroke and other head trauma may face a significant obstacle: current cooling devices can't penetrate very deeply into the brain.

Feeding solid foods to infants before 6 months of age can increase the risk of allergies

Exclusive breastfeeding for at least 6 months may prevent the onset of allergic symptoms later in life

How does the immune system isolate and destroy intruders?

Dendritic cells are the body's "watchdogs". They recognize and then degrade pathogens, isolating characteristic fragments that are recognized by the immune system thus triggering targeted responses.

Women who harbor multiple HPV type infections are at higher risk for cervical lesions

The risk for developing the tissue abnormalities, or lesions, that typically precede cervical cancer is much higher for women infected with multiple genotypes of the human papillomavirus (HPV) than previously reported.

New wireless reflux disease technology more comfortable, not more effective

A wireless device that measures the acidity of stomach contents backwashed into the esophagus allows patients to avoid some of the nose pain and throat discomfort associated with the conventional wired monitor used to manage hard-to-treat gastroesophageal reflux disease.

Don't smoke and eat fish to keep your sight later in life

New research from Australia and the U.S. into Age-related Macular Degeneration, has found that cigarette smoking increases the risk but eating fish protects against it, and hormone replacement therapy makes no difference whatsoever.
