USP announces two new standards related to elemental impurities

As part of its ongoing efforts to help ensure the quality of medicines, the U.S. Pharmacopeial Convention (USP) has announced two new standards related to elemental impurities: General Chapters <232> Elemental Impurities-Limits and <233> Elemental Impurities-Procedures. The new standards provide procedures for the detection of selected impurities in drug products based on modern analytical methods, as well as acceptable limits for their presence based on toxicity data and exposure levels.

Polarization Gating Spectroscopy may detect pancreatic cancer

By simply shining a tiny light within the small intestine, close to that organ's junction with the pancreas, physicians at Mayo Clinic's campus in Florida have been able to detect pancreatic cancer 100 percent of the time in a small study.

Scientists decipher structure of bacterial injection needles at atomic resolution

The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response.

Non-invasive imaging technique measures specific brain chemical changes

Alzheimer's disease (AD) is a major neurodegenerative disorder that affects millions of people worldwide. New and accurate techniques for early diagnosis are critical. Pravat K. Mandal, PhD, and his colleagues have developed a completely non-invasive brain imaging technique to measure specific brain chemical changes. This provides a signature of the early stages of AD from the hippocampal region of the brain.

High blood sugar in combination with high insulin levels causes fatty deposits in the heart

The impaired substrate metabolism of diabetes patients is often expressed in an increase in fatty deposits in the cells of the heart muscle. Until now, the exact cause of this was unknown. Now, researchers at the MedUni Vienna in the Division of Endocrinology and Metabolism of MedUni Vienna in cooperation with the MR Centre of Excellence Vienna have shown that high blood sugar in combination with high levels of insulin - not an influx of fats - results in such deposits within a few hours.

ACS symposium focuses on biomimetics

Combining the secrets that enable water striders to walk on water and give wood its lightness and great strength has yielded an amazing new material so buoyant that, in everyday terms, a boat made from 1 pound of the substance could carry five kitchen refrigerators, about 1,000 pounds.

Breast implant materials may deter cancer cells from dwelling and thriving

One in eight women in the United States will develop breast cancer. Of those, many will undergo surgery to remove the tumor and will require some kind of breast reconstruction afterward, often involving implants. Cancer is an elusive target, though, and malignant cells return for as many as one-fifth of women originally diagnosed, according to the American Cancer Society.
