To assess the utility of a single stain for both mast cell count and bacillary index (BI), 50 skin-biopsie patients were stained with Fite-Faraco (FF) stain, viewed under oil immersion and BI calculated using the Ridley's logarithmic scale, and mast cells counted as the number of cells per mm2. Mean mast cell count per mm2 at the tuberculoid pole was lowest in TT 7.9 and highest in BT 14.23. At...

Although classification of astrocytic tumors is standardized by the WHO grading system, which is mainly based on microscopy-derived, histomorphological features, there is great interobserver variability. The main causes are thought to be the complexity of morphological details varying from tumor to tumor and from patient to patient, variations in the technical histopathological procedures like ...

Currently, histopathological tissue examination by a pathologist represents the gold standard for breast lesion diagnostics. Automated classification of histopathological whole-slide images (WSIs) is challenging owing to the wide range of appearances of benign lesions and the visual similarity of ductal carcinoma in-situ (DCIS) to invasive lesions at the cellular level. Consequently, analysis o...

A 40-year-old woman presented with an itchy erythematosquamous change of a café-au-lait spot in her face. The onset of this change occurred just after her relocation. The café-au-lait spot had been irradiated by laser approximately 20 years ago. Clinically, there was a coin-sized erythema with a slight scale on the pigmented lesion in the left lateral orbital region. Histopathologically, the le...

Colon cancer classification has a significant guidance value in clinical diagnoses and medical prognoses. The classification of colon cancers with high accuracy is the premise of efficient treatment. Our task is to build a system for colon cancer detection and classification based on slide histopathological images. Some former researches focus on single label classification. Through analyzing l...

Background: Sirtuin1 (Sirt1) is a member of highly conserved proteins and has been implicated as a tumor promoter as well as a tumor suppressor. One of the mechanisms involves deacetylation of retinoblastoma protein, thereby inhibiting the tumor suppressor function. No study has been reported on the expression of Sirt1 in retinoblastoma. Methods: We assessed the expression of Sirt1 in sections ...

Providing an improved technique which can assist pathologists in correctly classifying meningioma tumours with a significant accuracy is our main objective. The proposed technique, which is based on optimum texture measure combination, inspects the separability of the RGB colour channels and selects the channel which best segments the cell nuclei of the histopathological images. The morphologic...

Objectives: To assess histopathological characteristics of oral leukoplakia among snuff users and non-users. Material methods: The descriptive cross-sectional study was conducted at different hospitals in Khyber Pakhtunkhwa. consisted 60 cases which 30 were non-users features assessed both groups. SPSS 20 used for the evaluation analysis data. Results: observed mean age 50.3 years. In users, 56...

Changes in kidney homeostasis due to diabetes can cause oxidative stress which then caused tissue damage that leads diabetic nephropathy. Clinacanthus nutans extract is known contain antioxidants are reported play an important role the body’s defense system against minimize damage. This study aims know effect of leaf administration on histopathological features rats model. A total 35 were induc...

Avian colibacillosis is a high-prevalence chicken farm disease caused by avian pathogen-ic Escherichia coli (APEC). It necessary to identify and look up the bacterial activity stave off decline in performance. This study aimed determine pathogenetic of APEC within broiler chickens on duodenum, jejunum, ileum histopathology comparison. The samples were collected from total 40 broilers, obtained ...
