Rapid Diagnostic Tests Inspired By Nature
Date: Oct-02-2012By mimicking nature's own sensing mechanisms, bioengineers at UC Santa Barbara and University of Rome Tor Vergata have designed inexpensive medical diagnostic tests that take only a few minutes to perform. Their findings may aid efforts to build point-of-care devices for quick medical diagnosis of sexually transmitted diseases (STDs), allergies, autoimmune diseases, and a number of other diseases. The new technology could dramatically impact world health, according to the research team...
Scientists Identify Simple Formula That Allows Bacteria To Engulf Food In Waves
Date: Oct-02-2012Move forward. High-five your neighbor. Turn around. Repeat. That's the winning formula of one of the world's smallest predators, the soil bacteria Myxococcus xanthus, and a new study by scientists at Rice University and the University of Texas Health Science Center at Houston (UTHealth) Medical School shows how Myxococcus xanthus uses the formula to spread, engulf and devour other bacteria...
New Maryland Law Enables Consumers To Select Qualified Physicians
Date: Oct-02-2012A new Maryland law effective today requires physicians who publicize board certification to announce their certifying board as well as their speciality. Additionally, the law states the only acceptable, certifying boards, are the 24 members of the American Board of Medical Specialities (ABMS), the authoritative speciality board for all U.S. physicians. Dr...
Novel, Biocompatible Nanoparticles Glow Through 3 Centimeters Of Biological Tissue
Date: Oct-02-2012An international research team has created unique photoluminescent nanoparticles that shine clearly through more than 3 centimeters of biological tissue -- a depth that makes them a promising tool for deep-tissue optical bioimaging. Though optical imaging is a robust and inexpensive technique commonly used in biomedical applications, current technologies lack the ability to look deep into tissue, the researchers said...
Attention Study Gives New Insight Into Boredom
Date: Oct-02-2012Although boredom is often perceived as having no significance, being only temporary and quickly fixed by a simple changed in the environment, it can also be a chronic and prevalent stressor that may severely impact people's health. The state of boredom can be triggered very easily, for example, listening to a long and uninteresting school lecture, driving a long distance alone in the car, or waiting, what seems like forever, for a doctor's appointment...
Landmark Survey Reveals Governments Failing To Address Pandemic Of 'Global Untreated Cancer Pain'
Date: Oct-02-2012Governments around the world are leaving hundreds of millions of cancer patients to suffer needlessly because of their failure to ensure adequate access to pain-relieving drugs, an unprecedented new international survey reveals. The new data, released to the public during the ESMO 2012 Congress of the European Society for Medical Oncology in Vienna, paints a shocking picture of unnecessary pain on a global scale, said Prof Nathan Cherny, lead author of the report from Shaare Zedek Medical Center, Jerusalem, Israel, Chair of the ESMO Palliative Care Working Group...
Resistance In Melanoma Patients Delayed By Combination Of Targeted Treatment Drugs
Date: Oct-02-2012Combined treatment with two drugs targeting different points in the same growth-factor pathway delayed the development of treatment resistance in patients with BRAF-positive metastatic malignant melanoma. The results of a phase I/II study of treatment with the kinase inhibitors dabrafenib and trametinib were published in the New England Journal of Medicine and released online to coincide with a presentation at the European Society for Medical Oncology meeting in Vienna...
Teenagers Who Are Sleep-Deprived Are At Increased Risk Of Insulin Resistance
Date: Oct-02-2012A new study suggests that increasing the amount of sleep that teenagers get could improve their insulin resistance and prevent the future onset of diabetes. "High levels of insulin resistance can lead to the development of diabetes," said lead author Karen Matthews, PhD, of the University of Pittsburgh Department of Psychiatry. "We found that if teens that normally get six hours of sleep per night get one extra hour of sleep, they would improve insulin resistance by 9 percent...
Breast-Conserving Treatments Are Available But Are They Being Offered To Enough Women?
Date: Oct-02-2012Two new studies presented at the ESMO 2012 Congress in Vienna, Austria show how improvements in breast cancer treatments are making it possible for more women to conserve their breasts following therapy, but raise concerns about whether enough women are being offered these approaches. Prof Michael Gnant, a surgical oncologist from Vienna's Medical University, who was not involved in the studies, commented: "Clearly, advances in interdisciplinary preoperative approaches have contributed to the revolution in breast surgery that has provided huge benefits to women in the last three decades...
The Challenges Of Cancer Prevention: Myths And Misunderstandings Hamper Prevention Efforts
Date: Oct-02-2012New insights on the global fight to prevent cancers were presented during the ESMO 2012 Congress of the European Society for Medical Oncology in Vienna. The studies highlight the challenges of overcoming misunderstandings about how important lifestyle factors are in reducing cancer risk. "These studies highlight the fact that a large proportion of the European population does not particularly like the idea of 'self-responsibility' for personal cancer prevention - that is, changing their habits and lifestyle accordingly...
