Comparison of immunohistochemical expression of vascular endothelial growth factor and CD105 in oral squamous cell carcinoma: Its correlation with prognosis.

Objectives: Compare and correlate immunoexpression of vascular endothelial growth factor (VEGF) and CD105 in oral squamous cell carcinoma (OSCC), and correlate its expression with the prognosis of the patient.

Materials And Methods: A retrospective study was carried out on total of 49 cases of OSCC. Detailed demographic and clinical data were obtained, and tissue sections were stained with hematoxylin and eosin to grade the tumor.

Multiplex polymerase chain reaction detection of selected bacterial species from symptomatic and asymptomatic non-vital teeth with primary endodontic infections.

Aim: The aim of the present study was to investigate the presence of selective anaerobic microorganisms in primary root canal infections of symptomatic and asymptomatic non-vital teeth with periapical pathosis using multiplex polymerase chain reaction.

Methods: A total of 100 root canal samples (50 from symptomatic and 50 from asymptomatic teeth) were obtained from patients with primary endodontic infections. DNA extracted from the samples was amplified by using specific primers for the 16S rRNA gene of each bacterium, and semiquantification was done to analyze the prevalence of microorganisms and their correlation to clinical features.

Culture-based identification of pigmented Porphyromonas and Prevotella species in primary endodontic infections.

Background. The most common species isolated from primary endodontic infections are black-pigmented bacteria. These species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature.

Do the presence of Barr bodies in male jail inmates indicates criminality: A pilot study.

Background: Cytogenetic studies from past decades have shown that interphase cells of female cats contain a densely stained chromatin mass in their nuclei called as Barr bodies (BBs) named after the scientist Murray Barr. BBs are unique chromatin structures formed due to the condensation of the X-chromosome. Many psychopathic disorders originate from defective genes including the multiple X syndromes.

A histochemical comparison of methyl green-pyronin, and hematoxylin and eosin for detecting apoptotic cells in oral squamous cell carcinoma, oral leukoplakia, oral submucous fibrosis and normal oral mucosa.

Analysis of apoptotic cells in oral pathological states could be useful for determining the rates of tissue turnover, which would help determine prognosis. The use of histochemical stains such as hematoxylin and eosin (H & E) and methyl green-pyronin (MGP) can provide a simple and cost-effective method for detecting apoptotic cells. We compared the efficacy of MGP and H & E for detecting apoptotic cells in oral squamous cell carcinoma (OSCC), oral leukoplakia (OL), oral submucous fibrosis (OSMF) and normal oral mucosa (NOM).
