The aim of the present study was to evaluate effect different staining techniques on applicability and accuracy tooth cementum annulation (TCA) method. Nine decalcination techniques, 8 dehydration protocols were applied in 3 teeth from persons a known age. Black white, color images histological sections captured. An x- ray taken each they photographed. Researchers asked observe both black/white...

background and aims. mineral trioxide aggregate and calcium hydroxide are considered the gold standard pulp-capping materials. recently, portland cement has been introduced with properties similar to those of mineral trioxide aggregate. histopathological effects of direct pulp capping using mineral trioxide aggregate and portland cements on dog dental pulp tissue were evaluated in the present 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...

This review aimed to highlight the historical perspectives focused on histological stains and their application in teaching research. While early histologists used indigenous substances like alizarin, carmine, saffron stain tissues, modern utilize techniques that study cellular organelles within tissues. Despite advent of new staining techniques, modification old ones, decrease use natural dyes...

this study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especiallyin brachial enlargement. sixteen adult female rats were divided into two groups. diabetes was induced in one group by alloxan agent. both groups became pregnant by natural matting. on days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offsprin...

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...

AIMS In the present study, the efficacy of multi-scale photoacoustic microscopy (PAM) was investigated to detect, map, and quantify trace amounts [nanograms (ng) to micrograms (µg)] of SWCNTs in a variety of histological tissue specimens consisting of cancer and benign tissue biopsies (histological specimens from implanted tissue engineering scaffolds). MATERIALS AND METHODS Optical-resolutio...

Brain mapping research in most neuroanatomical laboratories relies on conventional processing techniques, which often introduce histological artifacts such as tissue tears and tissue loss. In this paper we present techniques and algorithms for automatic registration and 3D reconstruction of conventionally produced mouse brain slices in a standardized atlas space. This is achieved first by const...
