Tissue refractive index as marker of disease.
The gold standard in histopathology relies on manual investigation of stained tissue biopsies. A sensitive and quantitative method for in situ tissue specimen inspection is highly desirable, as it would allow early disease diagnosis and automatic screening. Here we demonstrate that quantitative phase imaging of entire unstained biopsies has the potential to fulfill this requirement. Our data in...
متن کاملProtein Body Composition in Cuburbita maxima Cotyledons as Determined by Energy Dispersive X-Ray Analysis.
Energy dispersive x-ray analysis was used to study the composition of certain protein body components in Cucurbita maxima cotyledons. The globoid crystal was rich in phosphorus, potassium, and magnesium. This elemental composition provides further evidence that the globoid crystal in squash cotyledon protein bodies is composed of phytin, a myoinositol hexaphosphoric acid salt of potassium and m...
متن کاملSize and conformation of Ficoll as determined by size-exclusion chromatography followed by multiangle light scattering.
The characteristics of the glomerular filtration barrier (GFB) are challenging to measure, as macromolecular solutes in blood may be metabolized or transported by various cells in the kidney. Urinary solute concentrations generally reflect the cumulative influence of multiple transport processes rather than the intrinsic behavior of the GFB alone. Synthetic tracer molecules which are not secret...
متن کاملProtein dynamics determined by backbone conformation and atom packing.
To study the factors determining the collective motions in thermal, conformational fluctuations of a globular protein, molecular dynamics simulations were performed with a backbone model and an atomic-level model. In the backbone model, only the C alpha atoms were explicitly treated with two types of pairwise interactions assigned between the C alpha atoms; atom-packing interactions to take int...
متن کاملRefractive Index Compensation in Over-Determined Interferometric Systems
We present an interferometric technique based on a differential interferometry setup for measurement under atmospheric conditions. The key limiting factor in any interferometric dimensional measurement are fluctuations of the refractive index of air representing a dominating source of uncertainty when evaluated indirectly from the physical parameters of the atmosphere. Our proposal is based on ...
