ON GOLD CHLORIDE AS A STAINING AGENT FOR NERVE TISSUES

Investigation of acoustic properties of silica coated gold nanoparticle as contrast agent for Ultrasonography

Interoduction: Ultrasound images have often low contrast due to small differences in acoustic impedance between different tissues. Air or gas microbubbles that surrounded by membrane are most of the contrast agents in ultrasound imaging. Problems such as instability in sound pressure and inability in penetrating from the blood vessel into body tissues limited the use of microbubbles into the in...

Radioiodine as a possible triggering agent for pemphigus foliaceus

Pemphigus foliaceus (PF) is an autoimmune blistering disease presenting in endemic and sporadic forms. The typical presentation is recurrent shallow erosions in a seborrheic distribution. PF has also been found in association with autoimmune diseases such as autoimmune thyroid disease (e.g. toxic nodular goiter and Hashimoto’s thyroiditis). In some patients, PF appears to be triggered by radioi...

Introducing a combined Leishman-Giemsa stain as a new staining technique for avian blood smears

Background: The use of conventional stains including Giemsa, Wright and Leishman have become an essential tool for differential diagnosis of cells in peripheral blood. Aims: The aim of the study was to develop a new combination of Leishman-Giemsa (L&G;) stain for avian blood smears and to compare its efficacy with conventional staining methods. Methods:<...

NeuroproteCtioN as a treatmeNt for Nerve ageNt survivors

Fluorescent staining for proteins on polyacrylamide gels with 5-dimethylamino-1-naphthalenesulfonyl chloride (dansyl chloride).

A simple and sensitive post electrophoresis fluorescent staining technique for proteins on polyacrylamide gels using 5-dimethylamino-1-naphthalene sulfonyl chloride (dansyl chloride) has been developed. Dansyl chloride staining increases the sensitivity, 0.125 micrograms protein per band can be visualised by this technique. The staining method appears to be applicable to all types of proteins i...
