Pulmonary fibrosis is one of the most common and serious types of lung disease. Now researchers have developed an in vitro lung tissue-on-a-chip system that mimics lung fibrosis, offering rapid testing of potential new anti-fibrotic treatments.
Tissue-engineering technique based on a novel cylindrical scaffolding design seeded with collagen-secreting cells yields grafts for articular cartilage repair with superior mechanical strength and durability.
Yarn weaved from carbon nanotubes monitors brain control of organ functions in rats, paves way for disease diagnosis and treatment at single nerve level.
NIH researchers have devised a biochemically formulated patch of dissolvable microneedles for the treatment of type 2 diabetes. The biochemical formula of mineralized compounds in the patch responds to blood chemistry to manage glucose automatically. In a proof-of-concept study performed with mice, the researchers showed that the chemicals interact in the bloodstream to regulate blood sugar for days at a time.
Hari Shroff, Ph.D., chief of the National Institute of Biomedical Imaging and Bioengineering’s lab section on High Resolution Optical Imaging (HROI), and his team have spent the last few years developing optical microscopes that produce high resolution images at very high speed. After his lab develops these new microscopes, they release the plans and software for free, so any researcher can replicate the advances made at NIH. This latest microscope builds on previous improvements that Shroff’s l…
