A study by USC researchers has identified two competing proteins, DSP and DPP, that influence the strength of tooth enamel. Over-expression of DSP increases enamel hardness, while over-expression of DPP creates pitted and chalky enamel prone to fracture and wear.
A rapid assessment survey found a type of sea squirt, Didemnum sp., in Cobscook Bay that can damage ocean floor habitats and commercial species. The bay is an important source of seafood, but further research and monitoring are needed to determine the extent of the threat.
Half of high blood pressure patients reporting no medical care or guidance, despite 50 million adults affected. Guidelines for ER evaluation and management needed to address this issue.
Scientists discover a new connection between macrophages and lymph vessels in the eyes, which could lead to new therapies for eye diseases like diabetic retinopathy. The study also suggests that this link may be universal and involved in spreading cancer.
Researchers propose that human TSE-contaminated material was the cause of BSE, transmitted via animal feed, and originated from the Indian subcontinent. The study calls for global cooperation between public health, agriculture, and industry organizations to thoroughly investigate the sources of animal by-products.
Researchers found that pomegranate fruit extracts inhibit the overproduction of MMP enzymes in human cartilage cells, slowing cartilage degradation in osteoarthritis. The findings suggest a potential therapeutic effect for consuming pomegranate fruit extract to protect cartilage.
Researchers discovered that CD11b-positive macrophages play a crucial role in the development of lymphangiogenesis in the cornea during inflammatory conditions. These macrophages transform into endothelial cells or stimulate the division of existing lymphatic cells, leading to the formation of new lymph vessels.
A study found that the BRCA2 gene mutation significantly increases cancer risk in men, with higher rates of prostate, pancreatic, pharyngeal and bone cancers. The mutation is associated with an increased risk of developing these cancers, particularly among younger men.
A study published in The Lancet found that minimally invasive coil treatment is more effective than neurosurgical clipping for ruptured brain aneurysms, resulting in a 24% reduction in mortality and disability. Long-term follow-up data showed that the early survival advantage was maintained up to 7 years.
Researchers at Virginia Tech created a new type of composite material that can be molded into bipolar plates with high electrical conductivity, good mechanical properties, and ease of manufacture. The material's properties exceed industry standards and will enable faster and more efficient production of fuel cell stacks.
