background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...

objective: lumbar spinal canal stenosis (lscs) has prominent position in spinal disorders of the elderly. ligamentum flavum hypertrophy plays a dominant role in narrowing of the lscs. there are some clues that ligamentum flavum hypertrophy is associated with diabetes mellitus. our objective was comparison of histological properties of ligamentum flavum in lumbar spinal canal stenosis patients w...

In a recent publication we described a microscopical technique called Ultramicroscopy, combined with a histological procedure that makes biological samples transparent. With this combination we can gather three-dimensional image data of large biological samples. Here we present the theoretical analysis of the z-resolution. By analyzing the cross-section of the illuminating sheet of light we der...

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.

The aim of our work was to study the expression of apoptosis in the cephalic region in human embryonic and fetal material. Twelve human embryos and fetuses were processed by routine histological technique and then studied using the Boehringer-Mannheim Company kit for TUNNEL technique. Rich appearance of apoptotic cells was typical for mesenchyme and for tissues of the mesenchymal origin. Disper...

background and objectives:rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry.methods: four to five mm thick paired...

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...

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...
