摘要:
A method and a corresponding system for obtaining a serum mid-infrared spectroscopic profile using Fourier-transform infrared spectroscopy (FTIR) are described. The method comprises acquiring FTIR spectra for dried sera and preprocessing the FTIR spectra of sera by differentiation and smoothing to enhance weak spectral features and to remove baseline variations. The preprocessed FTIR spectra are normalized to a common intensity range, the normalization being performed in a spectral sub-region defined by strongest infrared (IR) absorption for a protein to obtain the serum spectroscopic profile. The serum spectroscopic profiles provide a basis to diagnose immunoglobulin disorders or to quantify serum immunoglobulin levels.
摘要:
A mesh sponge is formed as a batting of multiple layers of a tubular mesh material defining a pocket. The pocket may house a cleaning aid article, for example, a bar of soap or a structural form. Liquid soap may be used in conjunction with the mesh sponge and structural form, which provides a solid feel to the user. The pocket in the mesh sponge may house a bladder that is filled with liquid soap. The bladder may be porous or contain one or more valved openings to facilitate the excretion or dispensing of the liquid soap upon squeezing of the bladder by a user.

摘要:
The discovery that apolipoprotein B exhibits spectral features in the mid IR spectrum that make it identifiable within blood serum leads to the invented use of a statistical correlation between a concentration of apolipoprotein-B (apoB) in a sample of blood serum and infrared spectral features of the blood serum sample to produce a test for apoB. A method for providing such a test, and tests produced by the method are taught.
摘要:
A number of reagent-free infrared spectroscopic diagnostic and analytical methods have been established previously, making use of dry biofluid films. For example, this approach has successfully measured high concentration analytes of serum and urine. However, a number of low concentration diagnostically relevant analytes presently elude detection by infrared spectroscopy. This is due in part to their relatively low concentration and in part to spectral interference by other strongly absorbing constituents. The applicability of the technique would be broadened substantially if it were possible to separate and concentrate, lower concentration analytes, e.g. serum creatinine and urine proteins, from the obscuring presence of relatively high concentration compounds. The invention disclosed achieves this is through microfluidic sample preconditioning based upon laminar fluid diffusion interfaces. Preferential separation of certain low concentration serum and urine analytes of clinical interest that presently lie just below the threshold of detection by infrared spectroscopy is provided.
