95 gestion that viruses, from the type which appears to be of molecular proportions to those which are essentially microorganisms in the bacterial sense-have one (at least) distinguishing characteristic in common,-parasitism. From this he deduces: "We would suppose that the larger viruses were organisms which had lost the power to synthesise some factor or factors essential for their growth and...

Summa ry The growth of our knowledge of normal and pathological histology has been accelerated by two periods of spectacular technical developments. The first, a t the end of the nineteenth century, produced most of the dye staining methods for sections that are now in use. The second, dating from the 1950's to the present time, has seen the application of electron microscopy, histochemistry an...

In this paper we prove that the extended triplicate graph (ETG) of finite paths admits product E-cordial, total product E-cordial labelings. We show that ETG of finite paths of length n where n ∉ {4m-3|m∈N} admits E-Cordial, total E-cordial labelings and also we prove the existence of Z3 – magic labeling for the modified Extended Triplicate graph.

background primary small round blue cell tumors (srbct) in sinonasal comprise histogenetically diverse entities with overlapping morphologic features. because of the limited initial biopsy tissue materials, differential diagnostic difficulties may arise, and as they have different management, exact diagnosis and classification are very important. conclusions the results of our study indicate th...

BACKGROUND In recent years, there is an increasing tendency to use diced cartilage grafts in rhinoplasty surgery for improving dorsum contour irregularities. This study was designed to compare graft resorption between three techniques of diced cartilage using surgical blade, electrical grinder and grater in rabbit model. METHODS Thirteen New Zealand rabbits were divided into three groups. Thr...

9 Abstract Many of the time-honored methods for histopathological analysis of tissue sections have been superseded by new histological techniques, immunohistochemistry, or other diagnostic tests. Some of the dyes that were used for generations are no longer available, and chemicals used in some older methods are now considered hazardous. Additionally, the histotechnologists and pathologists fam...
