Half of sildenafil samples purchased on the internet were fake

Around half of the Viagra samples purchased on the Internet were counterfeit, according to researchers who are today announcing a new technique that detects counterfeit medicines at the British Pharmaceutical Conference.

Amyloid growth can occur independently of oligomers

Improperly folded proteins are normally destroyed. But in a wide range of diseases, including prion (from proteinaceous and infectious) diseases and neurodegenerative diseases like Parkinson disease and Alzheimer disease, amyloid fibrils, or plaques--misshapen proteins that aggregate into characteristic ropelike configurations--accumulate in tissue.

Microdebrider better than CO2 laser for removal of most pediatric airway lesions

Citing improved safety and effectiveness at lower cost, a major medical center has adopted the microdebrider to replace the CO2 laser for removal of most pediatric airway lesions, including stenoses, granulation tissue, and cysts.

Protein that causes juvenile Batten disease also plays a key role in normal cell function

The aberrant protein that causes juvenile Batten disease, a fatal neurodegenerative disorder of childhood, also plays a key role in normal cell function, Duke University Medical Center researchers have found.

Researchers have discovered a possible way to distinguish lethal from localized prostate cancers

If future studies show their test -- measuring the level of activity of a signaling pathway called Hedgehog -- can predict which prostate cancers will spread, the results could revolutionize decision making processes for prostate cancer patients, the researchers say.

Study provides insight on how DNA code is turned into instructions for protein construction

A team of scientists from the Hebrew University of Jerusalem and the Weizmann Institute of Science has revealed the structure of a cellular editor that “cuts and pastes” the first draft of RNA straight after it is formed from its DNA template.

International research sheds light on Escherichia coli

An unprecedented picture of how bacteria latch on to human cells has been published by UK, French and US scientists. They have produced a finely detailed model of one of the tools used by some of the nastiest varieties of the stomach bug, Escherichia coli, to stick to and gain entry to host cells.

Ultra-sensitive measurement technique shows how biomolecular motors carry out essential tasks

In the human body, hundreds of different types of biomolecular motors help carry out such essential tasks as muscle contraction, moving chromosomes during cell division, and reloading nerve cells so they can repeatedly fire.

High-resolution images reveal the molecular rearrangements that rotavirus uses to break into cells

High-resolution images constructed by researchers at Children's Hospital Boston and Harvard Medical School reveal the molecular rearrangements that rotavirus – the most common cause of severe, dehydrating diarrhea and vomiting in children worldwide – uses to break into cells.

Drug developers should take a different approach to snake venom and heart medications

With the help of snake venom and sophisticated laboratory testing, scientists believe they've uncovered the reason why a group of new heart medications were doing some patients more harm than good.

Researchers map structure of anti-cancer molecule and open the door to the creation of more effective cancer treatments

Scientists at Emory University, in collaboration with researchers at three national laboratories, have solved the structural puzzle of how an emerging class of promising cancer drugs works to halt cell division. The discovery potentially opens the door to the creation of more effective cancer treatments.

What is Telomere crisis?

Telomere crisis is an important early event in the development of breast cancer, and its occurrence can be identified with precision, according to recent findings by a team of scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at San Francisco.

Advances in biomedical imaging could lead to more sensitive screening tests for cancer-fighting drugs

Advances in biomedical imaging are allowing UC Davis researchers to use mice more effectively to study cancers comparable to human disease. The system can distinguish different stages of cancer and could lead to more sensitive screening tests for cancer-fighting drugs.
