Soft drink could enhance effects of an anticancer drug

2010-11-11
(Press-News.org) Experiments with an artificial stomach suggest that a popular lemon-lime soft drink could play an unexpected role in improving the effectiveness of an oral anticancer drug. The experiments produced evidence that patients will absorb more of the unnamed drug, tested in Phase I in clinical trials, when taken with "flat" or degassed Sprite. The study appears in ACS' Molecular Pharmaceutics, a bi-monthly journal.

Faraj Atassi and colleagues note that efforts are underway to develop more anticancer medications that patients can take by mouth. However, biological variations among patients — due to variations in stomach acidity and other factors — can reduce the effectiveness of oral anticancer drugs. Such was the case with the unnamed anticancer drug in the study, identified only as "Compound X." There were wide differences in how the drug was absorbed in the first patients who took it.

The scientists combined Compound X with Captisol, a substance that helps improve the solubility of drug ingredients, and turned to the artificial stomach. That glass-and-plastic device is used to study how drugs and foods dissolve through the GI tract. They showed that Sprite seemed to control stomach acidity in a way likely to allow greater absorption of the drug into the body. Based on the results, the scientists suggest that patients in future clinical trials take the drug with Sprite.

U of A researchers can predict heart transplant patient's health earlier

2010-11-11
Michael Mengel, a pathology researcher with the Faculty of Medicine & Dentistry, has found a new way to analyze biopsies from heart transplant patients by looking at their genes. This allows him to make an early prediction whether the transplant is working. This is extremely important in heart transplant patients because a successful outcome depends completely on doing a biopsy of the heart tissue and prescribing treatments if necessary. In other organs transplants, doctors can use other measurements. It's hoped the new technology and process developed in the Faculty ...

Guardian angels for seeds

2010-11-11
The seeds that you plant in your backyard garden next spring — and farmers sow in their fields — may have a guardian angel that helps them sprout, stay healthy, and grow to yield bountiful harvests. It's a thin coating of chemicals termed a "seed treatment" that can encourage seeds to germinate earlier in the season, resist insects and diseases, and convey other advantages. These new seed defenders are the topic of an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine. C&EN Senior Business Editor Melody Voith describes a boom ...

Stress takes its toll in Parkinson's disease

2010-11-11
CHICAGO --- We all know that living a stressful lifestyle can take its toll, making us age faster and making us more susceptible to the cold going around the office. The same appears to be true of neurons in the brain. According to a new Northwestern Medicine study published Nov. 10 in the journal Nature, dopamine-releasing neurons in a region of the brain called the substantia nigra lead a lifestyle that requires lots of energy, creating stress that could lead to the neurons' premature death. Their death causes Parkinson's disease. "Why this small group of neurons ...

New neuronal circuits which control fear have been identified

2010-11-11
Fear is an adaptive response, essential to the survival of many species. This behavioural adaptation may be innate but can also be a consequence of conditioning, during the course of which an animal learns that a particular stimulus precedes an unpleasant event. There is a large amount of data indicating that the amygdala, a particular structure in the brain, is strongly involved during the learning of "conditioned" fear. However, until now, the underlying neuronal circuits have remained largely unknown. Now, research involving several Swiss and German teams and a researcher ...

Researchers see ethical dilemmas of providing care in drug detention centers

2010-11-11
(Garrison, NY) Organizations that seek to provide health care, food, and other services to people held in drug detention centers in developing countries often face ethical dilemmas: Are they doing more good than harm? Are they helping detainees or legitimizing a corrupt system and ultimately building its capacity to detain and abuse more people? Such dilemmas are explored in an article coauthored by Nancy Berlinger and Michael Gusmano, research scholars at The Hastings Center, along with Roxanne Saucier and Daniel Wolfe of the Open Society Institute, and Nicholas Thomson ...

Circuit regulating anti-diabetic actions of serotonin uncovered by UT Southwestern researchers

2010-11-11
DALLAS – Nov. 11, 2010 – New findings by researchers at UT Southwestern Medical Center suggest that serotonin – a brain chemical known to help regulate emotion, mood and sleep – might also have anti-diabetic properties. The findings, appearing online this week in Nature Neuroscience, also offer a potential explanation for why individuals prescribed certain kinds of anti-psychotic drugs that affect serotonin signaling sometimes have problems with their metabolism, including weight gain and the development of diabetes. "In this paper, we describe a circuit in the brain ...

News tips from a special issue of the International Journal of Plant Sciences

2010-11-11
The November/December issue of the International Journal of Plant Sciences explores the current state of our knowledge of natural selection in plants. "Plants were crucially important to Darwin's development of the theory of natural selection (six of his books were on plants)," writes Jeffrey Conner, a biologist at Michigan State University and guest editor of the issue. "Plants are still crucially important to the study of natural selection in the field." The issue features reviews and original research articles that explore multiple aspects of this complex topic. ...

Caltech scientists describe the delicate balance in the brain that controls fear

2010-11-11
PASADENA, Calif.—The eerie music in the movie theater swells; the roller coaster crests and begins its descent; something goes bump in the night. Suddenly, you're scared: your heart thumps, your stomach clenches, your throat tightens, your muscles freeze you in place. But fear doesn't come from your heart, your stomach, your throat, or your muscles. Fear begins in your brain, and it is there—specifically in an almond-shaped structure called the amygdala—that it is controlled, processed, and let out of the gate to kick off the rest of the fear response. In this week's ...

Research provides new leads in the case against drug-resistant biofilms

2010-11-11
PROVIDENCE, R.I. [Brown University] — When a foreign object such as a catheter enters the body, bacteria may not only invade it but also organize into a slick coating — a biofilm — that is highly resistant to antibiotics. Like sophisticated organized crime rings, biofilms cannot be defeated by a basic approach of conventional means. Instead doctors and drug developers need sophisticated new intelligence that reveals the key players in the network and how they operate. New research led by biologists at Brown University provides exactly that dossier on some key proteins in ...

Growing sorghum for biofuel

2010-11-11
MADISON, WI November 8, 2010 -- Conversion of sorghum grass to ethanol has increased with the interest in renewable fuel sources. Researchers at Iowa State University examined 12 varieties of sorghum grass grown in single and double cropping systems. The experiment was designed to test the efficiency of double cropping sorghum grass to increase its yield for biofuel production. The author of the report, Ben Goff, found that using sorghum from a single-cropping system was more effective for the production of ethanol. Since most of the ethanol currently produced in the ...
