Recent geophysical data shows Mauna Loa's summit caldera swelling at a rate of 2-2.5 inches per year, indicating magma accumulation. Scientists warn that this could be a precursor to an eruption, which would be the first time imaged with precise clarity.
Researchers investigated the physiological roles of VEGF isoforms in embryonic vascular development, finding that different isoforms have distinct functions and are necessary for normal vessel branching frequency and width. The study uses transgenic mice to explore the role of soluble and heparin-binding VEGF isoforms in vessel growth.
A large-scale clinical trial found that patients treated with the two-drug regimen had a much higher rate of major liver injury compared to those taking isoniazid. The study confirms CDC recommendations for frequent monitoring of patients, highlighting the importance of laboratory testing to detect early liver injury.
Researchers found that ICAD-deficient flies lack apoptotic DNA fragmentation due to impaired CAD protein expression. Meanwhile, DNase II-deficient flies accumulate fragmented DNA and trigger an immune response. This study reveals a crucial role for innate immunity in apoptotic DNA degradation.
Researchers discovered Foxd3 as a crucial gene regulating embryonic stem cell fate and pluripotency. The gene is required for normal embryonic development, including the formation of inner cell mass and extraembryonic tissues.
A national clinical trial with 80 Parkinson's patients showed that high-dose coenzyme Q10 slowed functional decline by 44%, particularly in everyday activities. The therapy needs to be tested in a larger trial before it can be recommended.
Researchers create DOAS system that separates fresh air supply from cooling and heating functions, reducing carryover of recirculated air and eliminating damp spots. This approach could save $2 per square foot in new construction and reduce operating costs by up to 60-70%.
Researchers at the Norwegian Cancer Society have discovered that certain types of fish fat contain compounds with anti-cancer properties. The study suggests that these compounds may be used to develop new treatments for various types of cancer.
Researchers have developed a new surgical procedure for Parkinson's disease, bilateral subthalamotomy, which has shown promising results in improving motor symptoms and activities of daily living. After two years of follow-up, patients exhibited approximately 50% improvement in motor symptoms and significant reduction in medication doses.
Methadone treatment is being expanded to office-based practices for patients with addiction, aiming to make it more accessible. Hair analysis has been found to be a significant advance in assessing exposure to antiretroviral therapies and monitoring patient response to indinavir, an anti-HIV drug.
Researchers found that treating people with early-stage glaucoma immediately can delay disease progression and slow vision loss. The study followed 255 patients with early stage glaucoma in at least one eye, finding that treatment led to a slower rate of disease progression.
A landmark study shows that high doses of coenzyme Q10 can slow the progression of Parkinson's disease, measured by movement difficulty or disability. The study found significant reductions in motor disabilities, mental function, and mood among participants taking the nutrient.
A phase II study found that coenzyme Q10 can slow the rate of functional decline in Parkinson's disease by improving mitochondrial function and energy-producing reactions. The study showed that higher doses of coenzyme Q10, up to 1,200 mg/day, were safe and more effective than lower doses.
Researchers collected sprite data during a balloon campaign to study the electromagnetic signature of lightning strokes that produce sprites. The results indicate that negative cloud to ground strokes produce sprite halos seven times more often than positive strokes, suggesting an energy imbalance in the mesosphere.
The new center combines multiple research areas, including molecular devices, nanofabrication, and selective chemistry. Regular seminars feature the researchers of the Center for Nanoscale Science.
Physicians must consider ethical obligations when treating patients using alternative medicine, including risks and benefits of therapies. A list of factors to aid risk-benefit analysis has been provided by authors, emphasizing the need for thorough investigation and in-depth discussions with patients.
A new theory suggests that the Earth's surface features can be explained by rapid changes in crustal plate direction due to convection in the mantle. The research uses powerful computer systems to model the Earth's interior in three dimensions, revealing dynamic processes that shape our planet.
A study published by University of Pennsylvania School of Medicine reveals the Foxd3 gene plays a vital role in maintaining stem cells' pluripotency. The findings suggest that Foxd3 is essential for embryonic development and has diagnostic significance for human embryonic stem cells.
A recent survey of 968 women aged 15-59 found that nearly 60% were told their pain is normal by their Ob/Gyn or a friend/family member. Chronic pelvic pain affects many lives, but often takes years to receive an accurate diagnosis.
The study provides strongest support for mutation accumulation (MA) theory, proposing that aging results from accumulated mutations of genes kept in check early in life. This theory suggests that genes associated with diseases like Huntington's and cancer have noticeable effects late in life.
Scientists are exploring how molecular genetics can improve classical biological control by finding natural enemies well adapted to target invasive pests. Genetically modified crops with toxins like Bt may also be compatible with natural enemies, offering a new approach to controlling unwanted insect pests.
A new study published by the American Heart Association found that MRI stress tests can predict fatal and nonfatal heart attacks in patients with certain conditions. The study used MRI stress tests on 279 men and women referred for further testing after initial ultrasound screenings were inconclusive.
The city has attracted significant investment from big companies in various sectors, but the lack of co-ordinated planning and strategic vision has hindered regional development. Despite this, the core urban area has experienced a significant turn-round with population growth and new housing developments.
A study of 45 male identical twin pairs found no difference in disc degeneration between occupational drivers and their non-driving twin brothers. The researchers suggest shifting attention from degenerative changes to other explanations for the link between driving and back problems.
