New miniaturised chip dramatically reduces time taken for DNA analysis
A team of researchers at the Universitat Autònoma de Barcelona has developed new miniature sensors for analysing DNA. The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain. These sensors can be applied to many different tasks, ranging from paternity tests and identifying people to d...Caloric restriction won't dramatically extend life span in humans: UCLA research
Severely restricting calories over decades may add a few years to a human life span, but will not enable humans to live to 125 and beyond, as many have speculated, evolutionary biologists report. "Our message is that suffering years of misery to remain super-skinny is not going to have a big payoff in terms of a longer life," said UCLA evolutionary biologist John Phelan. "I once heard some...Hospitalizations because of chicken pox down dramatically since implementation of vaccine
Since the introduction of the varicella (chicken pox) vaccine in 1995, hospitalizations and doctor visits because of chicken pox have dropped dramatically, according to a study in the August 17 issue of JAMA. Varicella vaccine is recommended for routine immunization of children aged 12 to 18 months and for older susceptible children and adults in the United States, according to background...Simple idea to dramatically improve dengue vaccinations
An innovative new study explains, for the first time, the failure of previous attempts to vaccinate against the four known Dengue viruses, and it suggests a very simple solution ?injecting the four vaccines simultaneously at different locations on the body. A mosquito-born disease, Dengue kills tens of thousands of people per year and sickens 100 million more. Known as "bone-break disease,...Lack of a key enzyme dramatically increases resistance to sepsis
According to the new study, the presence of caspase-12, which appears to modulate inflammation and innate immunity in humans, increases the body's "vulnerability to bacterial infection and septic shock" while a deficiency confers strong resistance to sepsis. This new discovery suggests that caspase-12 antagonists could be a potentially useful in the treatment of sepsis and other inflammatory and...Support Services found to Dramatically Impact Pediatric Health Care
A new study shows providing behavior and development support to existing health care dramatically improves the quality of pediatric health care and parenting practices.// Researchers from the John Hopkins Bloomberg School of Public Health followed nearly 6,000 children from 15 sites which was designed to bridge the gap between families and physicians. It places specialists in the pediat...MRI Technology Dramatically Improves Breast Cancer Diagnosis
Doctors at the University of Kansas Hospital have a new tool in the fight against breast cancer, but it’s the same technology that has been helping doctors// in other areas improve diagnoses for years… magnetic resonance imaging (MRI). For the past several months Dr. William Smith and Dr. Marc Inciardi, dedicated breast radiologists in the hospital’s breast imaging center, have been wo...Obesity Surgeries Have Jumped Dramatically Since 1998
Obesity surgeries for patients between the ages of 55 and 64 in the United States soared from 772 procedures in 1998 to 15,086 surgeries in 2004—a nearly 2,000 percent increase, according to a new report by HHS’ //Agency for Healthcare Research and Quality. The report, the latest of several studies that AHRQ has done on obesity surgery, also found a 726 percent increase in surgeries a...Diabetes Drug Dramatically Boosts Potency of Platinum Chemotherapy
A widely used diabetes drug dramatically boosted the potency of platinum-based cancer drugs when administered together to a variety of cancer cell lines and to mice with tumors, scientists from Dana-Farber Cancer Institute report. Combining a platinum chemotherapy agent and the diabetes drug rosiglitazone halted or shrank mouse tumors as much as three times more effectively than eithe...ProtoKinetix's AAGP Dramatically Increases Recovery Rate of Cryopreserved Stem Cells
