introduction: formocresol is widely used in primary teeth pulpotomies; however it is known to have several side effects. the purpose of this study was to assess pulpal changes of primary teeth pulps after pulpotomy with sodium hypochlorite and formocresol. materials and methods: in this randomized clinical trial, 22 teeth were selected. these teeth were randomly divided into 2 groups (formocres...

unilateral orchidectomy (uo) is required when further breeding potential is important. it is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. in this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. results of the study showed that each of the surgica...

PREMISE OF THE STUDY A novel preparation technique was developed to examine fruits and seeds of plants with exceptionally hard or brittle tissues that are very difficult to prepare using standard histological techniques. METHODS AND RESULTS The method introduced here was modified from a technique employed on fossil material and has been adapted for use on fruits and seeds of extant plants. A ...

Learning objectives Gliomas, the most frequent tumours occurring in the CNS, are defined and graded on the basis of histological features to predict prognosis and management. Owing to biological heterogeneity, the histological diagnosis and expected clinical outcome do not match in a significant number of patients. The combination of imaging and gene expression, referred to as “radiogenomics,” ...

Background: Traditional techniques for preparation of teeth for histological analysis include: 1) Ground section of non-decalcified tooth and view by polarized light. 2) Decalcify the tooth and then section and stain as per soft tissue. 3) Cryomicrotomy -non-decalcified tooth is immersed rapidly in liquid nitrogen and sectioned with a cryostat using a heavy-duty freezing microtome. Objectives: ...

Abstract: A technique is described which enables quantitative histological data to be recovered from conventional digital images. Methodology is developed around the concept of image ratios, which are shown to be invariant to scene geometry and illumination intensity. Key to the success of this technique, is a function which maps uniquely from a vector if image ratios to the corresponding vecto...

Breast cancer is the most common cancer in women in Western countries after skin tumors. Successful treatment depends on many factors, relies on clinical examination, diagnostic procedures, pathologic evaluation, and good therapy decision. The Pathologic diagnosis should be the determining factor in the decision on therapeutic approach. There are several methods of obtaining tissue samples. The...

Objective measurements of tissue area during histological examination of carcinoma can yield valuable prognostic information. However, such measurements are not made routinely because the current manual approach is time consuming and subject to large statistical sampling error. In this paper, a semi-automated image analysis method for measuring tissue area in histological samples is applied to ...
