A new study found that clot-busting drugs can save legs as effectively as invasive surgery, reducing the need for open surgical procedures by over 30%. The experimental drug, recombinant urokinase, showed no significant difference in death or amputation rates between surgical and non-surgical patients.
Scientists have discovered that Helicobacter pylori resistance to metronidazole is caused by mutation in the rdxA gene. This gene codes for an enzyme that converts metronidazole into hydroxylamine, a mutagen and cancer-causing chemical.
A new study found no benefit to earlier steroid treatment for premature infants, but raises concerns about potential harm. The study enrolled 371 very-low-birth-weight infants and found higher infection rates, slower growth, and smaller head size in those treated with dexamethasone.
Researchers have found that paraoxonase, an enzyme present in the blood, can prevent the oxidation of LDL cholesterol and reduce atherosclerosis. The discovery opens a possible new route to prevention of heart diseases.
The SOAR telescope, a state-of-the-art facility in Chile, will enable researchers to study the universe like never before. It will collect 3,400 times more light than the original telescope, allowing for observations of dimmer objects and stars at greater distances.
The UNC-CH physics and astronomy department has launched a new program called SOLAR, which allows North Carolina public school teachers and students to use and remotely control the Morehead Observatory telescope. The program offers students access to real scientific data and the opportunity to capture their own images of the universe.
A new study by University at Buffalo researchers found that smoking during pregnancy increases the risk of pre-term birth, low-birth weight babies, and small-for-gestational-age infants. Despite taking prenatal vitamins, these risks remain higher for smokers compared to non-smokers.
Researchers found that annual mammograms and clinical breast exams can lead to high false-positive rates, causing unnecessary anxiety and costly follow-up tests. The study suggests that up to 16 million US women may experience a false-positive result after 10 years of screening.
Researchers have successfully replicated human bone disorder McCune-Albright syndrome in mice using a novel animal model. The model utilizes a combination of normal and mutant stromal cells, which are mixed together before transplantation into immune-compromised mice.
