The determination of reducing sugars by titration of ferricyanide.

THE use of ferricyanide for the quantitative estimation of sugar was introduced by Hagedorn and Jensen [1923]. Their method has been extended to other sugars by Hanes [1929] and Hulme and Narain [1931]. These methods involve a preliminary heating for 15 minutes and a subsequent back titration. The fact that ferricyanide is only slightly coloured would seem to make it valueless for a direct titr...

Permanganate—A New Fixative for Electron Microscopy

During the early phases of tissue sectioning for electron microscopy, virtually all of the standard cytological fixatives were tried. Of these, osmium tetroxide appeared to give the best preservation, and this was further improved by buffering the fixative solution at a slightly alkaline pH (Palade (1)). A variant developed by Dalton (2) contains Os04 in a chromate-dichromate system. Formalin h...

Evaluation of Streck tissue fixative, a nonformalin fixative for preservation of stool samples and subsequent parasitologic examination.

We undertook a study to evaluate Streck tissue fixative (STF) as a substitute for formalin and polyvinyl alcohol (PVA) in fecal preservation. A comparison of formalin, PVA, (mercuric chloride based), and STF was done by aliquoting fecal samples into each fixative. Stool specimens were collected in Haiti, and parasites included Cyclospora cayetanensis, Giardia intestinalis, Entamoeba coli, Iodam...

A cell shrinkage artefact in growth plate chondrocytes with common fixative solutions: importance of fixative osmolarity for maintaining morphology.

The remarkable increase in chondrocyte volume is a major determinant in the longitudinal growth of mammalian bones. To permit a detailed morphological study of hypertrophic chondrocytes using standard histological techniques, the preservation of normal chondrocyte morphology is essential. We noticed that during fixation of growth plates with conventional fixative solutions, there was a marked m...

A Preconditioning Method for Thin High Contrast

We present a method to precondition the discretized Lippmann-Schwinger in4 tegral equations which model time-harmonic scalar waves in the presence of a thin 5 inhomogeneous scatterer of high contrast. The preconditioner is based on asymptotic 6 results as the thickness of the third component direction goes to zero and requires 7 solving a two dimensional limiting formulation of the problem at t...
