Searching for the right pharmaceutical agent: survival as the indicator

Tumor cells divide fast. They thus require a high supply of components for their DNA, like purines. The biosynthesis of purines could now be a new point of attack for chemotherapy. However, without a natural model, the search for an inhibitor for a cellular process is like the proverbial search for a needle in a haystack. An American research team has developed a clever way to quickly conjure the desired "needle" out of the hay, presenting several candidates to act as starting points for the design of a purine synthesis inhibitor.

Short segments of sugar chains useful in search for new drugs for Alzheimer's

Heparansulfate, which is needed for normal fetal development among other things, is also important for the build-up of amyloid, morbid protein deposits that appear in several serious diseases. This is shown by Uppsala scientists in an article published in the Proceedings of the National Academy of Science.

Survey finds four in ten seniors do not take medications as prescribed

Four in 10 seniors told researchers in a recent national survey that they haven’t taken all the drugs their doctors prescribed for them in the past year – either because the costs were too high, because they didn’t think the drugs were helping them, or because they didn’t think they needed them.

Dramatic difference between breast cancers in US and Africa

A study comparing, for the first time, breast cancers from Nigeria, Senegal and North America has found that women of African ancestry are more likely to be diagnosed with a more virulent form of the disease than women of European ancestry.

Drugs targeted at muscle cells can be of use in the treatment of diabetes patients with insulin resistance

Type 2 diabetes is a clinical disease characterised by disruption to the metabolism of glucose and lipids as well as to the production of and physiological reactions to insulin.

Compound derived from cottonseed oil could help improve the effectiveness of chemotherapy at treating head and neck cancer

The findings, which will be presented Tuesday, April 19, at the American Association for Cancer Research annual meeting, could lead to a treatment that provides an effective option to surgically removing the cancer, helping patients preserve vital organs involved in speech and swallowing.

Herbal remedies and arthritis drugs can be a potentially dangerous mix

Herbal remedies and arthritis drugs can be a potentially dangerous mix, but it's not only patients who are ill informed about the risks, healthcare professionals are too, suggests a survey, reported in the Annals of the Rheumatic Diseases.

Rimonabant appears to reduce risk factors for heart disease in obese people

A new drug could substantially reduce the bodyweight, waist circumference, and risk factors for heart disease in obese people, according to results of a randomised trial published in this week’s issue of The Lancet.

Prisoners executed by lethal injection in the US may have experienced awareness and unnecessary suffering because they were not properly sedated

Lethal injection is the most common way people are legally put to death in the USA. It has eclipsed all other methods of execution because of public perception that the process is relatively humane and does not violate the US Constitution’s Eight Amendment prohibiting cruel and unusual punishment.

Statins help cut risk for advanced prostate cancer

In a 10-year study of more than 30,000 health professionals, researchers at Johns Hopkins and Harvard found that the longer men take cholesterol-lowering drugs such as statins, the far less likely they are to develop advanced prostate cancer.

Cost-effectiveness of drugs may vary across borders

A study published in the journal Value in Health reviews variations in estimates of cost-effectiveness of pharmaceuticals from country to country. Data showed that the results seen in one country are not necessarily applicable in another and that decision makers need to interpret data from other countries very carefully.

Plastic surgeons caution against unknown dangers of mesotherapy

The allure of shedding unwanted pockets of fat with a series of simple injections, known as mesotherapy, sounds too good to be true - and it just might be. According to an ASPS Device & Technique Assessment (DATA) Committee report published in the April 15 issue of Plastic and Reconstructive Surgery® (PRS), the official medical journal of the American Society of Plastic Surgeons (ASPS), patients should be wary of mesotherapy until the safety and effectiveness of the procedure are confirmed.

Researchers determine structure of binding site of colon-cancer drug Erbitux and its protein target

Researchers at the University of Pennsylvania School of Medicine have determined the precise molecular details of how Erbitux, a recently approved colorectal cancer drug, binds to its target on cancer cells. Knowing this chemical configuration will lead to better drug design for this family of cancer medications.

Scientists have discovered the mechanism that enables some CD4 T cells - the main target of HIV - to thwart the virus

The discovery, reported on April 13 in the online version of Nature, could open the door to an entirely new strategy for preventing the spread of HIV infection in the body's cells, according to the senior author of the study, Gladstone Institute of Virology and Immunology Director Warner C. Greene, MD, PhD.

Neurologists may have foot in the door to preventing Alzheimer’s before it starts

A study led by Mayo Clinic shows for the first time that a drug appears to have a slowing effect -- though limited -- on the progression from mild cognitive impairment to Alzheimer's disease. The findings will be published online in the New England Journal of Medicine on April 14.
