Researchers discovered that abnormal signals scattered across brain images, like a fireworks display, occur in patients who lose consciousness during seizures. In contrast, patients who don't lose consciousness have localized increases confined to the temporal lobe.
The US Pentagon is using cutting-edge sensors and software tests to protect against airborne hazards, including chemical and biological attacks. The system includes a multiscale weather forecast model, lidars, and other sensors to monitor air flow and turbulence around the building.
The NIST virtual surface calibration Web site provides free two-dimensional surface texture analysis software and a database of 10 different types of surface profiles. Manufacturers can validate software measurements and upload their own surface profiles to gain confidence in the accuracy of their software.
A 24-month study found that everolimus reduced intimal thickening and cardiovascular events, while sirolimus showed plaque regression. The results suggest that intravascular ultrasound measurements can be used as a valid surrogate for therapeutic intervention.
A study found that 73% of Canadian doctors can't estimate treatment costs within 25% of actual costs. They tend to underestimate expensive treatments and overestimate cheap ones, which can lead to unnecessary prescribing. The pharmaceutical industry's reluctance to provide cost information further hampers this process.
NIST's new portable 'rainbow' source enables precise color calibration across the entire visible light spectrum, addressing uncertainty in instruments measuring ocean and atmospheric properties. The highly portable source has been ordered by NOAA to reduce uncertainties in satellite calibrations.
Researchers developed a multi-gene molecular expression assay test to identify the quiescent state after heart transplantation and predict future occurrence of rejection. The test can help manage transplant patients' immunosuppression regimens and reduce discomfort during constant monitoring.
Scientists recommend overhaul of college introductory science courses to implement inquiry-based and active-learning strategies. This approach has proven to spark student interest in science, improve learning outcomes, especially among women and underrepresented minorities.
Researchers found that using an escrow settlement model settles cases more quickly and reduces litigation costs by 37%. The study, published in the Journal of Economic Behavior and Organization, showed that 69% of cases were settled out of court using this method.
Researchers at Yale University have discovered that curcumin, a compound found in turmeric, can correct the defective chloride channel responsible for cystic fibrosis. In tissue culture and mouse model systems, curcumin restored normal function to the nasal and rectal epithelia of CFTR mice.
A Temple University study found that patients with diseased aortic valves before receiving an LVAD have significantly lower survival to transplant rates. Conversely, those with normal aortic valves have higher survival rates, suggesting the importance of valve repair or upgrade in heart transplant optimization.
The study found that CellCept significantly reduced the risk of malignancy in patients following heart transplantation, with a 27% lower relative risk compared to azathioprine (AZA). The use of CellCept was also associated with a reduced risk of certain rare cancers, particularly skin cancer.
The NIST-developed standards provide guidelines for capturing, storing, and interpreting images of the eye to aid in diagnosing diabetic retinopathy. This approach allows healthcare professionals flexibility in choosing equipment, while ensuring quality image capture.
Luna Innovations plans to manufacture Trimetaspheres, soccerball-shaped molecules with enhanced MRI imaging capabilities. The company's ATP project enabled cost-effective production of nanomaterials with potential uses in consumer and military products.
A Mayo Clinic study found that most children with juvenile dermatomyositis (JDM) carry a particular gene from their mother, triggering an immune response. The research suggests that maternal cells may play a role in the development of JDM, a rare condition that causes inflammation and muscle damage.
Researchers investigate protein regulators of inflammation and hypertension, aiming to find direct cause-and-effect relationship between the two. The study could lead to new targets for treating high blood pressure, a major risk factor for heart disease.
Researchers found that RSV can remain dormant in lung tissue for over 100 days after initial symptoms disappear, suggesting a possible link to recurring wheezing and childhood asthma in infected children.
Researchers at Yale University developed an imaging test that identifies patients with schizophrenia with 97 percent accuracy. The test targets abnormalities in the auditory cortex and has potential as a powerful clinical tool for assessing schizophrenia.
Researchers found that the ultimate speed of magnetic switching is at least 1,000 times slower than previously expected. The experiment's results have significant implications for future hard disk computer drive technologies.
Researchers found fossils of green sulfur bacteria and oxygen-breathing sea reptiles coexisting in Oxford Clay sediment, challenging the standard interpretation of the fossil record. The team's discovery suggests that environmental conditions were dynamic during deposition, possibly due to climatic changes.
A randomized, prospective study found that tacrolimus + mycophenolate mofetil and steroids significantly reduce incidence of treated rejection and improve graft function compared to other regimens. The combination therapy also showed better lipid profiles and reduced risk of certain infections.
Researchers found that everolimus, when combined with cyclosporine and steroids, prevents transplant rejection and lowers risk of infection and complications more effectively than traditional anti-rejection therapy. A two-year study demonstrated the drug's improved safety and efficacy in preventing heart transplant rejection.
