The book consists of fourteen chapters with an appendix and an index. Chapters 1 to 10 and 13 deals with experiments on carbohydrates, lipids, proteins, en?ymes, saliva, milk, gastric digestion, pancreatic digestion, bile, blood and urine. Chapter II deals with colorimetry and chapter 12 deals with estimations of various constituents of blood. The book will be very useful to students of biochem...

We compared thiobarbituric acid colorimetry and boronate chromatography for measuring glycation of serum proteins. With 14C-glycated human albumin as a test material, both methods were acceptably linear and precise. However, comparable estimates (mmol/L) of albumin glycation ranged from 0.22 for thiobarbituric acid to 0.05 for boronate, representing yields relative to [14C]glycosylprotein of 42...

In this nonenzymatic colorimetric method, dichlorobenzoquinone chloroimine is used as a color reagent to measure uric acid in urine. This method is less subject to the interferences that make enzymatic methods unreliable and is inexpensive, simple, and fast.

This article is the second in a series of review articles discussing the applications of color science in the clinical practice of dentistry. This installment discusses the colorimetry, which is the science and technology used to quantify and describe physically the human color perception. Theories of color space and clinically portable colorimetric devices developed for determining tooth shade...

Hemoglobin in plasma can be determined by the color-developing action of 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid), which is oxidized to a colored form by a peroxidase-like effect of hemoglobin in the presence of hydrogen peroxide. Sensitivity, precision, and accuracy are discussed. The calibration curve is linear for hemoglobin concentrations up to 1 g/L; the minimum detectable conc...

We demonstrate a method for seamless transfer from a parent flat substrate of basically any lithographic top-down or bottom-up pattern onto essentially any kind of surface. The nano- or microscale patterns, spanning macroscopic surface areas, can be transferred with high conformity onto a large variety of surfaces when such patterns are produced on a thin carbon film, grown on top of a sacrific...
