Skp2 is a member of the F-box family of substrate-recognition subunits of SCF ubiquitin-protein ligase complexes that has been implicated in the ubiquitin-mediated degradation of several key regulators of mammalian G(1) progression, including the cyclin-dependent kinase inhibitor p27, a dosage-dependent tumor suppressor protein. In this study, we examined Skp2 and p27 protein expression by immu...

384 cholecystectomy specimens were examined during a period of one year from Oct 2005 to Oct 2006, in the department of Pathology, ASCOMS, Sidhra. Jammu, for studying the histological patterns of chronic cholecystitis, the frequency of associated mucosal changes, the age related incidence and the relationship of carcinoma with various mucosal changes. Majority of patients presented in the fourt...

Until now, the classification system of oral epithelial dysplasia is still based on the architectural and cytological changes, which relies on the observation of pathologists and is relatively subjective. The purpose of present research was to discriminate the oral dysplasia by the near-infrared Raman spectroscope, in order to evaluate the classification system. We collected Raman spectra of no...

Sum mary Ectodermal dysplasia is a group of symptoms affecting tissues and organs of ectodermal origin. In this study, conjunctival impression cytology technique which is a non-invasive method was performed in patients with ectodermal dysplasia to evaluate the effects on the conjunctiva. Six eyes of three patients with ectodermal dysplasia who were followed up by the Ophthalmology Clinic of Dic...

Introduction and objectives: The diagnosis of malignant and potentially malignant epithelial lesions of the oral mucosa cannot be based solely on clinical findings. Therefore, histologic evaluation of a representative biopsy specimen is necessary. However, the site for the biopsy is always a subjective choice that sometimes raises doubts about its representativeness. Colposcopy, a well-known gy...

Glucose transporters, such as GLUT-1, mediate the important mechanisms involved in cellular glucose influx, allowing cells to proliferate and survive. The significance of GLUT-1 expression in oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC) has been less explored, and no study has investigated it in relation to verrucous carcinoma (VC). We evaluated 30 cases each of OED, ...

FGFR3 mutations cause wide spectrum of disorders ranging from skeletal dysplasias (hypochondroplasia, achondroplasia, and thanatophoric dysplasia), benign skin tumors (epidermal nevi, seborrhaeic keratosis, and acanthosis nigricans), and epithelial malignancies (multiple myeloma and prostate and bladder carcinoma). Hypochondroplasia is the most common type of short-limb dwarfism in children res...

OBJECTIVES To investigate whether sputum cytology can be used to monitor epithelial cell changes in groups at high risk of lung cancer from exposure to radiation. METHODS Dysplasia of bronchial cells was investigated by means of sputum cytology in a group of 434 underground miners. 100 of them were not exposed, and 334 were exposed to 222Rn progeny at cumulative exposures < 450 working level ...

We report a case of adamantinoma of the tibia resembling fibrous dysplasia. The patient was a 55-year-old male, and complained of pain in the right lower leg. Roentgenographs showed a well demarcated osteolytic lesion with small foci of calcification and septation within the diaphysis of the distal tibia. The cortex was partially disrupted. Histologically, initial biopsy specimen showed fibrous...

We collected a series of 136 lung/bronchial and 56 matched lung parenchyma tissue samples from patients who underwent lung/bronchial biopsies and presented invasive carcinoma after lung surgery. The lung/bronchial samples included basal cell hyperplasia, squamous metaplasia, moderate dysplasia, adenomatous hyperplasia, severe dysplasia, squamous cell carcinoma and adenocarcinoma. Matched lung p...
