The Perme scale score as a predictor of functional status and complications after discharge from the intensive care unit in patients undergoing liver transplantation.

Objective: To assess the Perme mobility scale score as a predictor of functional status and complications in the postoperative period in patients undergoing liver transplantation.

Methods: The sample consisted of 30 patients who underwent liver transplantation. The patients were evaluated at two time points to determine their perception of pain, degree of dyspnea, peripheral muscle strength, and functional status according to the Perme scale.

Increased VEGFR2 and MMP9 protein levels are associated with epithelial dysplasia grading.

The present study aimed to compare levels of VEGFR2 and MMP-9 among control, epithelial dysplasia (ED) and oral squamous cell carcinoma (OSCC) groups. We analyzed 48 patients with oral leukoplakia (OL), 20 patients with OSCC and 21 patients without OL and OSCC. Immunohistochemistry of VEGFR2 and MMP9 were performed and compared among groups.

High expression of S100A4 and endoglin is associated with metastatic disease in head and neck squamous cell carcinoma.

The presence of cervical metastasis is responsible for high morbidity and mortality rates in individuals with head and neck squamous cell carcinoma (HNSCC). S100A4, a pleiotropic EF-hand calcium-binding protein, is expressed in various normal and cancer cell types. During cancer progression, molecular disturbances in S100A4 can modulate the activity and expression of pre-metastatic and metastatic genes.

Leptin receptor polymorphism Gln223Arg (rs1137101) in oral squamous cell carcinoma and potentially malignant oral lesions.

The purpose of this study was to assess the LEPR gene Gln223Arg polymorphism (rs1137101) in oral squamous cell carcinoma (OSCC) and in potentially malignant oral lesions (PMOL) in comparison to normal oral mucosa in a Brazilian population. Smokers (n = 89) were selected from a representative sample of 471 individuals from the general population of Montes Claros, Brazil. Participants were age and gender matched to patients with OSCC (n = 25) and oral epithelial dysplasia (n = 25).

Low expression of MSH2 DNA repair protein is associated with poor prognosis in head and neck squamous cell carcinoma.

Objective: This study aimed to investigate the expression of the MSH2 DNA repair protein in head and neck squamous cell carcinoma (HNSCC) in order to analyze its association with clinicopathologic factors and overall survival of patients.

Material And Methods: Clinical data and primary lesions of HNSSC were collected from 55 patients who underwent surgical resection with postoperative radiotherapy in Montes Claros, state of Minas Gerais, Brazil, between 2000 and 2008. Immunohistochemical reactions were performed to analyze MSH2 protein expression.

Th1 and Th2-like protein balance in human inflammatory radicular cysts and periapical granulomas.

Introduction: Chronic dental periapical lesions result from chronic inflammation of periapical tissues caused by continuous antigenic stimulation from infected root canals. Recent findings have suggested that T helper (Th) 1 and Th2-like cytokines are important in the pathogenesis of chronic periapical inflammatory diseases. However, the mechanisms regulating these immunoinflammatory pathways have not been fully elucidated.

Impact of the epithelial dysplasia grading and Ki67 proliferation index in the adjacent non-malignant mucosa on recurrence and survival in head and neck squamous cell carcinoma.

This study aimed to evaluate the association between several different aspects of disease in head and neck squamous cell carcinoma (HNSCC): morphological grading, Ki67 proliferation index (PI), invasive front, adjacent non-malignant mucosa (ANMM), recurrence and overall survival of the patients. Sixty-four fully reviewed and followed-up patients with primary HNSCC were matched according to recurrence of the lesion and placed in one of two groups of 32 cases. Chi-square and Fisher's exact tests were used to analyze the clinicopathological parameters between both groups of patients.

Increased circulating angiotensin-(1-7) protects white adipose tissue against development of a proinflammatory state stimulated by a high-fat diet.

Introduction: The aim of the present study was to evaluate the effect of a transgenic-induced chronic increase of Ang-(1-7) on the expression of inflammatory markers in adipose tissue and the metabolic profile in rats treated with high-fat diet.

Research Design And Methods: Transgenic rats expressing an Ang-(1-7)-producing fusion protein (TGR L-3292) and Sprague Dawley (SD) control rats 4 weeks old were treated for 8 weeks with a high-fat diet. Food intake and body weight were measured once a week.

DNA repair gene excision repair cross complementing-group 1 (ERCC1) in head and neck squamous cell carcinoma: analysis of methylation and polymorphism (G19007A), protein expression and association with epidemiological and clinicopathological factors.

Aims: To evaluate the associations of excision repair cross complementing-group 1 (ERCC1) (DNA repair protein) (G19007A) polymorphism, methylation and immunohistochemical expression with epidemiological and clinicopathological factors and with overall survival in head and neck squamous cell carcinoma (HNSCC) patients.

Methods And Results: The study group comprised 84 patients with HNSCC who underwent surgery and adjuvant radiotherapy without chemotherapy. Bivariate and multivariate analyses were used.
