Biocompatibility testing for a new implant material is necessary before clinical use. The materials bone scaffolding must also go through biocompatibility tests both in vitro and vivo. purpose of this study was to compare different staining methods histological preparations assess the tissues. Twenty Wistar rats (n= 20), aged 4 months, males, weighing about 250-350 g were divided into 2 researc...

The aim of this study was evaluation an organic germicide (Aquagerm) histological affects on Rainbow trout (Oncorhynchus mykiss) vital tissues. This new disinfectant is an aquatic antiseptic and mixed-oxidant disinfectant which is produced for the first time in Iran. This new product mechanism is based on oxidant properties of pro-sulphate which attack crucial structures of pathogens. In this s...

there is an impression that basal cell carcinomas (bcc) occurring in younger population may be of more invasive behavior in comparison to those arising in older patients. the purpose of this study was to investigate this hypothesis by comparing the histological types of bcc in a large cohort of young and old patients. a total of 287 histological reports and clinical records were evaluated. a co...

background many industrial devices have an excessive vibration which can affect human body systems. the effect of vibration on cochlear histology has been as a debatable problem in occupational health and medicine. objectives due to limitation present in human studies, the research was conducted to survey the influence of vibration on cochlear histology in an animal model. materials and methods...

BACKGROUND Magnetic resonance imaging (MRI) is increasingly used for research in hand osteoarthritis, but imaging the thin cartilage layers in the hand joints remains challenging. We therefore assessed the accuracy of MRI in detecting cartilage loss in patients with symptomatic osteoarthritis of the first carpometacarpal (CMC1) joint. METHODS Twelve patients scheduled for trapeziectomy to tre...

BACKGROUND Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is an accurate technique for sampling intraintestinal and extraintestinal lesions. However, cytology possesses certain limitations, which may be overcome if histological specimens are provided to the pathologist. AIM The aim of the study was to evaluate the accuracy of a newly developed 19G histology needle. METHODS ...

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...

BACKGROUND Accurate evaluation of immunostained histological images is required for reproducible research in many different areas and forms the basis of many clinical decisions. The quality and efficiency of histopathological evaluation is limited by the information content of a histological image, which is primarily encoded as perceivable contrast differences between objects in the image. Howe...

BACKGROUND DNA cytometry is a technique that allows densitometric analysis of nuclear DNA of cells and in this way the evaluation of DNA ploidy. OBJECTIVE The purpose of the present study was the evaluation of DNA ploidy in oral leukoplakia and oral lichen planus and correlation with histological dysplasia. METHODS We analyzed oral incisional biopsies from a group of 40 patients with oral l...
