Other risk factors included prior claims or lawsuits, male surgeon gender, advertising, time spent with patients, and co-management with optometrists.
Women with BRCA1 mutations have a poorer prognosis for breast cancer compared to those without the mutation. However, chemotherapy may improve survival rates for these patients. The study suggests that physicians should consider BRCA1 mutation status when making treatment decisions.
Research in the Journal of Industrial Ecology reveals that seemingly small e-commerce decisions can have significant environmental impacts, often shifting from positive to negative effects. Positive IT effects are typically limited to 5-20% reductions in pollution or energy use.
A new study provides reliable estimates of tropical sea surface temperature changes during the Paleocene-Eocene Thermal Maximum, fitting existing climate models. The findings support greenhouse climate theory and back global warming predictions, with significant implications for understanding current climate trends.
Researchers found that adding clay to fatty acid micelles greatly accelerated vesicle formation, and even demonstrated growth and division in these physical-chemical systems. This discovery offers a possible pathway for the evolution of living cells, with implications for understanding the origins of life on Earth.
The contest aims to honor biology experiments that are considered aesthetically pleasing, with a panel of experts screening nominations. The journal's goal is to encourage creative thinking among biologists about both famous and obscure experiments.
A study highlights the rise of vitamin D deficiency and rickets in children and pregnant women, particularly in immigrant groups in more temperate regions. Experts recommend extra dietary vitamin D supplementation for these populations to prevent deficiencies.
A landmark study provides accurate lifetime risk estimates for BRCA1 and BRCA2 gene mutations, with women carrying the BRCA1 gene facing a 54% risk of ovarian cancer. The study also highlights the negative impact of obesity and lack of exercise on breast cancer development in women with the mutation.
AstraZeneca's rosuvastatin has an inferior evidence base supporting its safe use compared to competitors. The company is facing unusually acute commercial pressure to force the drug into the market.
Researchers at Rockefeller University have discovered a new pathway, LRG-47, that can disarm TB and prevent its replication in mice. Strengthening this defense could lead to new treatments for latent TB infections, which affect an estimated 10 to 15 million people in the US.
Researchers at Lawrence Berkeley National Laboratory and NASA have developed a process to convert inedible wheat grass into activated carbon, absorbing nitrogen oxides and producing fertilizer. This technology could support a crew of six astronauts on a three-year Mars mission by recycling waste and conserving materials.
Lei Wang, a post-doctoral researcher, developed a method to insert an extra amino acid into proteins in live cells, expanding the genetic code. This breakthrough has opened new research horizons and could lead to highly specific genetic engineering.
Cumbre Inc. and University of Wisconsin-Madison researchers have published data on a new class of bacterial RNA polymerase inhibitors with major breakthrough potential, offering a powerful tool to study gene expression mechanisms and developing new antibiotics against bacterial pathogens.
Economic assessments of government R&D programs should be designed to measure productivity, quality, and reliability impacts on production and commercialization. A study's timing is critical, conducted within three to 10 years after a technology's significant marketplace impact.
A new class of compounds called CBR703 series inhibit RNA polymerase, a key enzyme in gene expression, and hinder the ability of bacteria to perform crucial catalytic functions. The compounds render RNA polymerase useless by binding to a specific place on the enzyme.
A new study published in The Lancet found that pulse-dye laser therapy (PDL) was effective in reducing acne symptoms by half at three months. PDL treatment was also well-tolerated and showed the largest effect within four weeks, suggesting it could be a promising alternative to daily conventional pharmacological treatments.
The Mayo Clinic research reveals a molecular mechanism involved in cell cycle regulation of the BRCA1 tumor suppressor gene. The team found that phosphorylation is required at certain stages to activate proteins associated with the BRCA1 gene.
The WIISARD project aims to provide emergency personnel with medical data on victims' conditions, track chemical or radioactive attacks, and ensure communication safety. The system utilizes radio-frequency tags, hand-held devices with location-based access to patient data, and a disaster database.
Researchers aim to enroll 75 men and women at three sites over three years to assess nicotine's effect on memory loss. The study, funded by a $1.5 million grant, will provide insights into potential treatments for mild cognitive impairment.
NIST is working on redundant elevator power systems and waterproof components to maintain safe operation during fires. The institute will use virtual reality simulation to test emergency evacuation procedures and collaborate with global experts to establish standards.
The USGS has discovered a vast area of green mineral olivine on Mars, suggesting that the planet's surface has been dry and free from recent water activity. This finding is significant as it implies that the Martian surface has not experienced significant chemical weathering due to liquid water.
A study found that nearly 50% of Parkinson's patients on levodopa therapy experience 'wearing off' within one to two years, causing symptoms to re-emerge before the next dose. This phenomenon is associated with motor and non-motor symptoms, as well as autonomic nervous system dysfunction.
A recent study found that the Arctic warmed significantly over the last decade, with the largest temperature increases occurring in North America. The study's results have direct connections to other NASA-funded research on declining sea ice extent, which could lead to positive feedbacks and further climate change.
The American Association for the Advancement of Science conducted a survey to identify top biopharma employers, with Genentech Inc. and Johnson & Johnson taking the first two spots. The survey analyzed responses from 910 Science readers and assigned scores based on specific characteristics.
Researchers identified a mutation in the human serotonin transporter gene, hSERT, associated with OCD, which may result from a genetic double hit increasing serotonin transport and leading to treatment resistance. The study provides insights into transporter function and potential tests for identifying and treating mental illness.
Researchers at the US Army Medical Research Institute of Infectious Diseases have developed a hantavirus vaccine that elicited a potent neutralizing antibody response in rhesus macaques. The vaccine, which uses a naked DNA approach, also provided protection against hamster infection when administered after exposure.
