High doses of COX-2 inhibitors and other NSAIDs are associated with a higher risk of death, according to the study. Patients taking high doses of celecoxib or rofecoxib were found to be at a strikingly higher risk of death compared to those not taking NSAIDs.
Researchers have identified a key role for dendritic cells in the development of childhood autoimmune disease, offering a new strategy for designing more effective treatments. The study found that dendritic cells mature and migrate to muscle tissue in response to an unknown trigger, highlighting a potential target for intervention.
A Johns Hopkins team found that aged rats with preserved cognitive abilities have a different mechanism for storing memories, relying on a different neurochemical device. This discovery could lead to the development of new preventive treatments and therapies based on what healthy older brains are doing.
New PCI guidelines address 'door-to-balloon time' of 90 minutes or less, emphasizing the importance of drug-eluting stents and anti-clotting medications. The guidelines also provide strategies for ensuring best possible patient outcomes and monitoring quality of care.
A Phase III clinical trial led by Duke University researchers found that edifoligide, a drug designed to prevent vein clogging in coronary bypass surgery, was no more effective than a placebo. The study showed that edifoligide had no significant impact on preventing neointimal hyperplasia, the process that causes veins to narrow and fail.
Scientists at Stanford University have developed a new microscope that allows them to track the real-time motion of a single protein down to its individual atoms. The device uses infrared light to trap and control forces on a functional protein, enabling researchers to monitor its every move in real time.
Researchers identified six gene variants associated with post-operative myocardial infarction following cardiac surgery. Collectively, these variants can explain 75% of the variability in heart damage, allowing physicians to identify high-risk patients and take precautions during and after surgery.
Researchers at Johns Hopkins Medicine successfully used a 3D map of the heart to perform cardiac ablation, eliminating the need for radiation exposure and improving patient safety. The technique used sensor-guided catheter and electro-anatomic mapping to precisely target diseased heart tissue.
Researchers at EMBL and universities in Heidelberg and Ulm found that blocking a specific signal within brain cells may help prevent cell death after a stroke. The study suggests new therapies could be developed by controlling a molecule involved in passing the signal.
Lorraine Iacovitti and her team have created a quicker method using defined additives from human origin to differentiate human embryonic stem cells into dopamine-producing neurons in three weeks. This new approach aims to reduce the risk of immune rejection by eliminating animal-derived substances.
A recent study found that pretreating vein grafts with edifoligide did not prevent graft failure in coronary artery bypass surgery, despite its potential to inhibit neointimal hyperplasia. The study included 3,014 patients and demonstrated the effectiveness of targeted drug delivery to specific tissues or organs.
A Brg1 mutation in mice reveals the importance of SWI/SNF complexes in beta-globin regulation and erythropoiesis. This study may provide insight into common ailments such as beta thalassemia and anemia. The findings highlight the significance of chromatin-remodeling complexes in development and physiology.
