1. MUSCLE DEPLETED OBESITY IN INDIVIDUALS SCREENED FOR COLORECTAL CÂNCER
RESUMO Contexto: O câncer colorretal (CCR) é o terceiro câncer mais incidente no mundo e a segunda principal causa de morte por câncer. Diminuições significativas da incidência e mortalidade podem ser alcançadas a partir da redução de fatores de risco e adesão às recomendações de estilo de vida saudável, bem como rastreamento da doença.

2. Watch and Wait, Worth It?
Abstract Background The surgery with total mesorectal excision recommended by R. J. Heald in 1982 is the gold standard. Rectal cancer (RC) surgery has a morbidity rate ranging from 6 to 35%, and it can cause functional issues such as sexual, urinary, and bowel dysfunction in the long term. Neoadjuvant chemoradiotherapy (CRT) has been gaining ground in patie

3. A functional interaction between the CCR5 and CD34 molecules expressed in hematopoietic cells can support (or even promote) the development of cancer
Abstract Inflammation and angiogenesis are linked to the development of cancer since both can support the establishment of a tumor-prone microenvironment. The CCR5 is a major regulatory molecule involved in inflammation. The CD34 molecule is commonly described as a hematopoietic stem cell marker, and CD34+ cells are involved in the regulation of distinct phy

4. Expressão não equilibrada do receptor de hidrocarboneto arílico nos linfócitos T CCR6+ CD4+ e CD4+ CD25+ do sangue periférico na artrite reumatoide
RESUMO Objetivo: Analisar o papel do receptor de hidrocarboneto arílico (AhR) nos linfócitos T CCR6+ CD4+ e CD4+ CD25+ no sangue periférico de pacientes com artrite reumatoide (AR). Métodos: Foi aplicada citometria de fluxo para determinar a proporção de células AhR positivas em linfócitos CCR6+ CD4+ e CD4+ CD25+ do sangue periférico e células mo

5. Association of NR1I2 gene polymorphisms and time of progression to AIDS
BACKGROUND The time of progression towards AIDS can vary greatly among seropositive patients, and may be associated with host genetic variation. The NR1I2 (PXR) gene, a ligand-activated transcription factor, regulates the transcription immune pathway genes and can therefore be targets of viral replication mechanisms influencing time of progression to AIDS.

6. CCR2 and CCR5 genes polymorphisms in women with cervical lesions from Pernambuco, Northeast Region of Brazil: a case-control study
Polymorphisms in chemokine receptors play an important role in the progression of cervical intraepithelial neoplasia (CIN) to cervical cancer (CC). Our study examined the association of CCR2-64I (rs1799864) andCCR5-Δ32 (rs333) polymorphisms with susceptibility to develop cervical lesion (CIN and CC) in a Brazilian population. The genotyping of 139 women wit

7. Genetic diversity and prevalence of CCR2-CCR5 gene polymorphisms in the Omani population
Polymorphisms in the regulatory region of the CCR5 gene affect protein expression and modulate the progress of HIV-1 disease. Because of this prominent role, variations in this gene have been under differential pressure and their frequencies vary among human populations. The CCR2V64I mutation is tightly linked to certain polymorphisms in the CCR5 gene. The c

8. Riscos e benefícios da colonoscopia após os 80 anos de idade: trabalhos prospectivo
OBJETIVO: avaliar riscos em colonoscopia após 80 anos de idade. PACIENTES E MÉTODOS: entre agosto de 2011 e janeiro de 2012 realizamos colonoscopias em 533 pacientes. Grupo A: idade entre 50 e 79 e Grupo B > de 80 anos. PARÂMETROS ANALISADOS: ASA, comorbidades, achados endoscópicos, tempo de chegada ao ceco, número de exames completos, dificuldade e co

9. Distribution of the CCR5delta32 allele (gene variant CCR5) in Rondônia, Western Amazonian region, Brazil
Since around 1723, on the occasion of its initial colonization by Europeans, Rondonia has received successive waves of immigrants. This has been further swelled by individuals from northeastern Brazil, who began entering at the beginning of the twentieth century. The ethnic composition varies across the state according to the various sites of settlement of e

10. Avaliação de polimorfismos em genes envolvidos na resposta imune inata de pacientes infectados com HIV-1 e sua influência na progressão à AIDS
Variações em genes de resposta imune têm sido associadas com a progressão à AIDS. Após a infecção pelo HIV a proteína sérica MBL é capaz de reconhecer N-glicanos presentes na glicoproteína viral gp120. Além disso, TLRs reconhecem diferentes moléculas antigênicas do vírus presentes no interior da célula, como o ssRNA viral reconhecido pelo TL

11. Influência do polimorfismo do gene do CCR-5 na transmissão materno-infantil do HIV-1 / The influence of polymorphism of the CCR-5 gene in the maternal-infant transmission of HIV-1
The main via of infection by Human Imunodeficiency Virus (HIV-1) in children is the maternal-infant transmission (MIT). Several factors can be associated to MIT of HIV- 1. It\ s believed that the homozygote individual to the allele CCR5-?32 are resistant to the infection of HIV-1. Considering that the role of the mechanisms involved are still controversial,

12. The effect of combined polymorphisms in chemokines and chemokine receptors on the clinical course of HIV-1 infection in a Brazilian population
Polymorphisms in genes that encode chemokines or their receptors can modulate susceptibility to human immunodeficiency virus (HIV) infection and disease progression. The objective of this study was to assess the frequency of polymorphisms CCR5-Δ32, CCR2-64I, CCR5-59029A and SDF1-3'A and their role in the course of HIV infection in a Southern Brazilian popul
