Reflection coefficients of permeant molecules in human red cell suspensions
The Staverman reflection coefficient, sigma for several permeant molecules was determined in human red cell suspensions with a Durrum stopped-flow spectrophotometer. This procedure was first used with dog, cat, and beef red cells and with human red cells. The stopped-flow technique used was similar to the rapid-flow method used by those who originally reported sigma measurements in human red ce...
متن کاملThe Microrheology of Red Blood Cell Suspensions
The general problem of microrheology is to predict the macroscopic flow properties of a material from a detailed description of the behavior of its constituent elements. This approach has been used to study suspensions of human red cells in plasma or Ringer's solution flowing steadily in rigid tubes 8-25 times the red cell diameter by observing individual cell motions under the microscope. The ...
متن کاملCell-Permeant Fluorescent Nanocomposites
Different types of molecular and nanoscale fluorophores are being developed for fluorescent imaging of live cells. Here we present their novel types and novel compositions. The dyes incorporated into nanostructures and their metal coordination complexes as well as carbon nanodots penetrate easily into the cell with the lack of toxicity, forming stable images. They are prospective for further fu...
متن کاملGeneralized Reflection Coefficients
I consider general reflection coefficients for arbitrary one-dimensional whole line differential or difference operators of order 2. These reflection coefficients are semicontinuous functions of the operator: their absolute value can only go down when limits are taken. This implies a corresponding semicontinuity result for the absolutely continuous spectrum, which applies to a very large class ...
متن کاملReflection coefficient and permeability of urea and ethylene glycol in the human red cell membrane
The reflection coefficient (sigma) and permeability (P) of urea and ethylene glycol were determined by fitting the equations of Kedem and Katchalsky (1958) to the change in light scattering produced by adding a permeable solute to a red cell suspension. The measurements incorporated three important modifications: (a) the injection artifact was eliminated by using echinocyte cells; (b) the use o...
