RESUMO
This study investigated the effect of pummelo extract (Citrus maxima) on biochemical, inflammatory, antioxidant and histological changes in NAFLD rats. Forty male Wistar rats divided into four groups were used: (1) control group; (2) fructose associated with high-fat diet - DHF; (3) normal diet + pummelo extract (50 mg/kg); and (4) FHD + pummelo extract. This was administered at dose of 50 mg/kg of the animal's weight, by gavage, for 45 days. Significant improvement in lipid profile, liver and kidney function, inflammation, oxidative stress markers was identified in group 4 compared to group 2. Regarding TNF-α and IL-1ß, group 2 showed higher values (respectively 142, 5 ± 0.7 and 560.5 ± 2.7 pg/mg protein) compared to group 4 (respectively 91.4 ± 0.9 and 402.1.4 ± 0.9 pg/mg protein), p < 0.05. Significant increases were found in SOD and CAT activities, respectively 0.10 ± 0.06 and 8.62 ± 1.67 U/mg protein for group 2 and respectively 0.28 ± 0.08 and 21.52 ± 2.28 U/mg of protein for group 4. Decreases in triglycerides, hepatic cholesterol and fat droplets in hepatic tissue were observed in group 4 compared to group 2. Results highlight that pummelo extract may be useful for prevent the development of NAFLD.

Cervical cancer is one of the most frequent cancers among Brazilian women and its relationship with the human papillomavirus (HPV) is well established. Objective: To analyze the presence of DNA/HPV using Hybrid Capture method for women in the city of Uruguaiana (RS). Methods: During the period of January to December 2015, 51 cervicovaginal samples were collected from patients who sought care at Basic Health Units in the city. After the collection, conventional and liquid-based cytological analysis was performed. Results: The results of the study indicate the prevalence of genital HPV infection in 5.9% of the samples; low-risk DNA/HPV was detected in 3.9% of patients of reproductive age (PIR); and 2.0% of PIR presented highrisk DNA/HPV. By stratifying the prevalence of HPV in age, we found positivity between 16 and 31 years. Conclusion: Conventional cytology is often inconclusive and, in such cases, using molecular biology methods that detect the DNA/HPV presence would be very useful.
O câncer de colo de útero é um dos mais frequentes entre as mulheres brasileiras e a sua relação com o Papilomavírus Humano (HPV) é bem estabelecida. Objetivo: Analisar a presença de DNA/HPV por meio do método de captura híbrida em mulheres no município de Uruguaiana (RS). Métodos: No período compreendido entre janeiro e dezembro de 2015, foram coletadas 51 amostras cervicovaginais de pacientes que buscaram atendimento nas Unidades Básicas de Saúde do município. Após a coleta, foi realizada a análise citológica convencional e em base líquida. Resultados: Os resultados encontrados no estudo indicam a prevalência de infecção genital por HPV em 5,9% das amostras analisadas, sendo DNA/HPV de baixo risco em 3,9% e DNA/HPV de alto risco em 2,0% das infecções. Ao estratificar a prevalência de HPV por faixa etária, observou-se positividade entre 16 e 31 anos. Conclusão: A citologia convencional pode ser, muitas vezes, inconclusiva e, nesses casos, utilizar uma metodologia de biologia molecular que detecte a presença do DNA/HPV seria muito útil.
