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.

Radiation for breast cancer not likely to increase heart attack risk

In 1973, two researchers published an article in the journal Lab Investigation saying that radiation to the breast area might damage the capillaries and restrict blood flow to the heart.

FDA issues "Critical Path Opportunities for Generic Drugs"

The U.S. Food and Drug Administration (FDA) today issued the "Critical Path Opportunities for Generic Drugs" report identifying many of the unanswered scientific questions that impede the development of generic versions of commonly used drugs.

New way to target and potentially treat tumors

Research teams at Yale University and the University of Rhode Island have demonstrated a new way to target and potentially treat tumors using a short piece of protein that acts like a nanosyringe to deliver tags or therapy to cells, according to a report in the Proceedings of the National Academy of Sciences.

Researchers use bacterium to obtain biopreservatives from food

The research group "Estudio de sustancias antagonistas producidas por microorganismos" (Antagonistic substances produced by microorganisms), part of the Microbiology Department of the University of Granada, has succeeded in isolating enterocin AS-48, which could have a medium-term use as food biopreservative.

Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.

Bacteria barge inside guard cells and initiate a powerful immune response

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought.

Scientists tackle cancer with different approaches

Studies presented at the 2007 meeting of the American Association for Cancer Research show how researchers are using the new, as well as the natural, to help design and test new drugs to treat cancer.

Eating cured meats increases the odds of developing chronic obstructive pulmonary disease

Frequent consumption of cured meats results in lower lung function test scores and increases the odds of developing chronic obstructive pulmonary disease (COPD), according to a large cross-sectional survey of adults in the U.S.

Use of computer-assisted drug design in drug discovery

Metabasis Therapeutics has announced that on March 27, 2007 at the American Chemical Society 233rd National Meeting and Exposition in Chicago, Dr. M. Rami Reddy presented, "Use of Computer-Assisted Drug Design in Drug Discovery: Limitations and Advantages of Available Computational Methods."

New, updated guidelines for esophageal reflux testing

Developed and approved by the American College of Gastroenterology, these guidelines summarize advances in gastroesophageal reflux disease (GERD) diagnostic testing and how they have modified the clinical management of esophageal disorders.

Bacteria can barge inside immune cells

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate a powerful immune response.

Researchers discover enzyme that is a natural tumor suppressor

Building on their 2005 discovery of an enzyme that is a natural tumor suppressor, researchers at the University of California, San Diego (UCSD) School of Medicine have now identified two variants of that enzyme which could provide new targets for therapies to treat diabetes, heart and neurological disease.

New regulatory mechanism for critical protein signaling domain

The study is being published in Science Express, an advanced online edition of the journal Science, on April 5. It will appear in the print version of Science later this spring.

National Public Health Week to focus on tobacco, public health threats

Tobacco remains the number one cause of preventable death, claiming more than 400,000 American lives annually.

Bioengineering heart parts

Some day, heart attack survivors might have a patch of laboratory-grown muscle placed in their heart, to replace areas that died during their attack.

Tiny injected gel particles to help chronic lower back pain

Scientists at The University of Manchester believe injections of tiny sponge-like particles could provide an alternative to major surgery in the treatment of chronic lower back pain.

Obesity at the time of prostate-cancer diagnosis dramatically increases the risk of dying from the disease

Obese men who are diagnosed with prostate cancer have more than two-and-a-half times the risk of dying from the disease as compared to men of normal weight at the time of diagnosis, according to a study by researchers at Fred Hutchinson Cancer Research Center.

Scientists alter electrical properties of cells inducing regeneration

Scientists at Forsyth may have moved one step closer to regenerating human spinal cord tissue by artificially inducing a frog tadpole to re-grow its tail at a stage in its development when it is normally impossible. Using a variety of methods including a kind of gene therapy, the scientists altered the electrical properties of cells thus inducing regeneration.

Primary targets of HIV-1 infection in human vagina identified

The primary targets of HIV-1 infection in the human vagina have been definitively identified in a new study published in the February 2007 issue of the journal Immunity. The findings are likely to guide development of new strategies that will prevent HIV-1 transmission.

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.
