A recent study published in the New England Journal of Medicine found that nearly 50% of severely obese youth develop metabolic syndrome. The condition is associated with worsening body mass index and insulin resistance, increasing risk for type 2 diabetes and cardiovascular disease.
Researchers have identified a protein called RIP140 that blocks the expression of UCP1, leading to increased energy expenditure and reduced fat accumulation. This discovery could lead to novel obesity treatments by increasing the activity of UCP1.
Experts argue that a new Global Environmental Organization (GEO) is needed to consolidate and coordinate environmental policy research, technology databases, and information clearing-houses. The UN Environment Programme is also overstretched and recommends focusing on science and co-ordination of scientific activities.
Scientists at Yale University used X-ray crystallography to image the self-splicing group-I intron and its associations with metal ions. This discovery reveals an evolutionarily ancient mechanism for RNA splicing, previously thought only possible in proteins.
Chalmers University and Konarka Technologies partner on third-generation photovoltaic products, enabling commercialization of flexible plastic-based solar technologies. This collaboration strengthens Konarka's intellectual property portfolio and enhances Chalmers' research capabilities.
Perfusion CT scans can reveal how much blood is present in the brain and how quickly it's moving, helping doctors decide on treatments such as surgery or clotbuster drugs. The technique has shown promise in assessing patients with stroke or carotid artery issues, potentially improving treatment outcomes.
Researchers have found that adding butyrate to an intravenous nutrition solution can cause the intestine to grow back and become more functional. This breakthrough offers hope for preterm infants and patients with Crohn's disease who rely on IV feeding due to surgically removed intestines.
Research suggests that filaments in the Galactic center are connected to areas of intense star formation, providing a link between thermal and non-thermal radio emission. The discovery sheds light on the phenomenon behind these striking features.
A new study will evaluate the effectiveness of a face-to-face support group for older adults with depression and HIV/AIDS. The intervention aims to improve coping mechanisms, quality of life, and social support.
Researchers found a shift in burden of disease as economic growth expands, with poorer women more affected. Obesity risk increases for those in lower-middle income countries above $2,995 per capita income.
CU researchers report consistent pattern in deuterium abundance, suggesting smaller amount of chemical evolution and higher infall of near primordial gas to the Milky Way galaxy. The findings provide a better understanding of galactic chemical evolution and its impact on the formation of stars, planets, and life.
A Temple virologist has received a grant to investigate the role of macrophages in HIV dementia complex. The researcher aims to understand how these cells contribute to the development of the condition, which affects 10% of AIDS patients, and explore potential therapies to target them.
Researchers studying lanthanum barium copper oxygen (LBCO) found that adding barium creates electron holes, which are necessary for superconductivity. The study suggests that fluid stripes may be essential for high-temperature superconductivity in these materials.
Researchers at UNC have identified a crucial role for a segment of Focal Adhesion Kinase (FAK) in activating the enzyme, which promotes cancer cell growth and metastasis. By making subtle changes to this region, they created a mutant protein that blocks FAK activity, suggesting potential therapeutic applications.
The FDA-approved Avastin increases patient survival by almost five months when combined with chemotherapy, showing a 10.6-month progression-free survival rate compared to 6.2 months in the control group.
A study found that doctors' initial diagnoses of uterine cancer were incorrect in over 25% of cases, with a significant number being misclassified as benign. The findings highlight the need for improved classification guidelines to prevent unnecessary surgeries and ensure accurate diagnosis.
Researchers found a new regulatory gene, SRG1, which blocks the expression of adjacent genes by physically preventing transcription factors from binding. This discovery provides evidence that junk DNA may have hidden functions and could be a common mechanism for regulating gene expression.
A new partnership between researchers and federal agencies has created a powerful tool to manage fire risk, with maps showing the extent of wildland/urban interfaces across the US. The analysis highlights the need for ecological principles in land-use planning, particularly in high-risk areas.
Researchers found three to four times more antibodies in Alzheimer's patients than healthy individuals, indicating a possible autoimmunity component to the disease. This discovery may lead to an early diagnostic test and more targeted treatments.
Scientists discovered that the Sirt1 mammalian gene promotes fat mobilization in mice, revealing a potential molecular link between calorie restriction and longevity. The study suggests that mimicking this effect with a drug could lead to health benefits without dieting.
A UCSD study uncovers how neurons in the brain sort information from electrical impulses, enabling coherent perception. Different neurons specialize in processing specific portions of the information, mimicking a musician reading their part in an orchestra.
Researchers at SLU have identified the first gene regulating programmed cell death in plant embryos, revealing a previously unknown mechanism. This discovery has significant implications for plant breeding and forestry, as it may help increase production and bolster resistance in plants.
Researchers found that combining Avastin with chemotherapy improves median survival, reduces risk of death and increases response rates in patients with advanced colorectal cancer. The study showed a nearly five-month improvement in patient survival, demonstrating the potential of targeting tumor blood supply as a viable treatment option.
Researchers found that COX-2 inhibitors significantly reduced postoperative pain, nausea and vomiting, and allowed patients to return home sooner. The study showed a 21% reduction in opiate use and improved patient satisfaction with minimally invasive surgery.
Researchers at UCSD find that altering neural activity can change the type of neurotransmitter produced by nerve cells, raising hope for treating disorders caused by problems with neurotransmitters. This discovery could provide flexibility for the growth and operation of the nervous system.
Airborne viruses were detected in 32% of office building air filters, with higher carbon dioxide levels linked to increased exposure risk. Researchers also found that healthcare workers treating SARS patients were at high risk of developing the disease due to endotracheal intubation.
A study of 60 Korean women with breast cancer found a high rate of genetic mutations in BRCA1 and BRCA2 genes. The average age of diagnosis was 40-50 years old, which is younger than in the US population. The study suggests different genetic and environmental factors may be at play for Korean patients diagnosed at a young age.
