Does Life resist desynchronisation?

Does resistin resist insulin?

Diabetes remains one of the oldest diseases all over the world and is the major cause of morbidity and mortality in human populations. The pathology is a consequence of a lack of insulin or resistance to insulin, resulting in an increase in blood glucose levels. Resistance to insulin is an important risk factor in the industrial world and is often associated with obesity. Taking the proportions...

Phosphonated polyurethanes that resist calcification.

Cardiovascular implant mineralization involving bioprosthetic materials, such as glutaraldehyde cross linked porcine aortic valves or synthetic materials such as polyurethanes, is an important problem that frequently leads to clinical failure of bioprosthetic heart valves, and complicates long-term experimental artificial heart device implants. Novel, proprietary, calcification resistant polyet...

Nanometer-Scale Patterning on PMMA Resist by Force Microscopy Lithography

Nanoscale science and technology has today mainly focused on the fabrication of nano devices. In this paper, we study the use of lithography process to build the desired nanostructures directly. Nanolithography on polymethylmethacrylate (PMMA) surface is carried out by using Atomic Force Microscope (AFM) equipped with silicon tip, in contact mode. The analysis of the results shows that the ...

Metallic resist for phase-change lithography

Currently, the most widely used photoresists in optical lithography are organic-based resists. The major limitations of such resists include the photon accumulation severely affects the quality of photolithography patterns and the size of the pattern is constrained by the diffraction limit. Phase-change lithography, which uses semiconductor-based resists such as chalcogenide Ge₂Sb₂Te₅ films, wa...
