The Gallyas method is a silver impregnation technique that is essential in the field of neuropathology because of its high sensitivity for the detection of argentophilic inclusion bodies in the central nervous system. In Japan, the Gallyas method has improved and is widely used as the "modified Gallyas method". However, this method is not popularly used in general pathology laboratories because...

The present invention provides a method of analyzing for a specific material in a sample using a sensor including a resonating member having resonating properties. The resonating member has a probe and a known material is disposed on or forms the probe. The method includes the steps of positioning the sensor proximate to the sample, detecting a force dependent change in the resonance properties...

In the assay of liver extract preparations, whether on pernicious anaemia cases or in laboratory animals, reticulocytosis has always been taken to be the index of therapeutic activity. When working with laboratory animals such as guinea-pigs or rabbits, it is essential that a rapid at the same time accurate method should be adopted for the counting of the reticulocytes. Usually workers have use...

We modify the J-matrix technique for scattering so that problems with long-range interactions are easily solved. This is done by introducing additional terms in the asymptotic three-term recurrence relation that take into account asymptotic effects of the potential. The solutions of this modified recurrence relation are a very good approximation of the exact scattering solution. Only a small nu...

We describe a modified colorimetric method for determining procainamide in plasma by use of a diazotization and coupling reaction with N-(1-naphthyl)-ethylenediamine dihydrochloride (Marshall's reagent). The sensitivity of the assay is increased twofold over the originally reported colorimetric method, and the lower limit of detection for the assay of a 1.0-ml plasma sample has been decreased t...

To overcome this, a simple modification can be made so that even in illuminated rooms this instrument can That strongyloidiasis should be excluded before initiating immunosuppressive therapy is widely known. In Indian leprosy manuals, strongyloidiasis is mentioned as a contraindication for steroid therapy in patients of leprosy. However, the fact that strongyloidiasis should be treated before i...

Visual cryptography encodes a secret image into n shares which are distributed to n participants. Pixel Sieve method was proposed recently to encode an image into shares, but the encryption quality is poor. In this paper an modified version of pixel sieve method is proposed to achieve more security than existing pixel sieve method. Based on key shifting scheme, the proposed method generates qui...
