13. Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland
ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativ

14. MODELOS ANIMAIS DE CARCINOGÊNESE COLORRETAL
RESUMO Introdução: O câncer de cólon e reto é bastante frequente na população e com elevado índice de mortalidade. Ele se desenvolve a partir da associação de fatores genéticos e ambientais e está relacionado a múltiplas vias de sinalização celular. Para o estudo da doença são utilizados cultivos celulares e modelos animais, que sejam capaz

15. Study of major genetic factors involved in pituitary tumorigenesis and their impact on clinical and biological characteristics of sporadic somatotropinomas and non-functioning pituitary adenomas
Genetic and functional aberrations of guanine nucleotide-binding protein, alpha stimulating (GNAS), aryl hydrocarbon receptor interacting protein (AIP), and pituitary tumor transforming gene (PTTG) are among the most prominent events in pituitary tumorigenesis. A cohort of Brazilian patients with somatotropinomas (n=41) and non-functioning pituitary adenomas

16. Biofilm production by clinical isolates of Pseudomonas aeruginosa and structural changes in LasR protein of isolates non biofilm-producing
ABSTRACT Introduction: Biofilm production is an important mechanism for the survival of Pseudomonas aeruginosa and its relationship with antimicrobial resistance represents a challenge for patient therapeutics. P. aeruginosa is an opportunistic pathogen frequently associated to nosocomial infections, especially in imunocompromised hosts. Objectives: Analyz

17. Avaliação da expressão do gene WWOX por avaliação imunohistoquímica, sua associação com marcador de angiogênese, expressão do p53, proliferação celular e parâmetros clinicopatológicos no câncer de colo uterino
Resumo Objetivo O presente estudo avaliou a expressão do WWOX, sua associação com características clinicopatológicas e com a expressão do p53, ki-67 (proliferação celular) e CD31 (angiogênese) em pacientes com carcinoma invasivo de células escamosas do colo uterino, ou simplesmente câncer do colo uterino (CCE). Métodos Foram avaliadas prospec

18. Homozygous sequence variants in the WNT10B gene underlie split hand/foot malformation
Abstract Split-hand/split-foot malformation (SHFM), also known as ectrodactyly is a rare genetic disorder. It is a clinically and genetically heterogeneous group of limb malformations characterized by absence/hypoplasia and/or median cleft of hands and/or feet. To date, seven genes underlying SHFM have been identified. This study described four consanguineou

19. Expressão de inibidores do ciclo celular na próstata canina com atrofia inflamatória proliferativa e carcinoma
RESUMO A expressão gênica de CDKN1A, CDKN1B e TP53, assim como imunomarcação de p21, p27 e p53 foram realizadas a fim de verificar o papel desses inibidores do ciclo celular na próstata canina com atrofia inflamatória proliferativa (PIA) e carcinoma prostático (PC). Foram obtidas70 amostras de próstata canina, sendo 15 de tecido normal, 30 de PIA e 2

20. Expression of E-cadherin, Slug and NCAM and its relationship to tumor invasiveness in patients with acromegaly
Pituitary adenomas account for 10–15% of primary intracranial tumors. Growth hormone (GH)-secreting adenomas account for 13% of all pituitary adenomas and cause acromegaly. These tumors can be aggressive, invade surrounding structures and are highly recurrent. The objective of this study was to evaluate E-cadherin, Slug and neural cell adhesion molecule (N

21. Radiotherapy modulates expression of EGFR, ERCC1 and p53 in cervical cancer
Cervical cancer is a public health problem and the molecular mechanisms underlying radioresistance are still poorly understood. Here, we evaluated the modulation of key molecules involved in cell proliferation, cell cycle and DNA repair in cervical cancer cell lines (CASKI and C33A) and in malignant tissues biopsied from 10 patients before and after radiothe

22. Polimorfismo da Enzima Conversora da Angiotensina (ECA D/I) em Pacientes com Insuficiência Cardíaca de Etiologia Chagásica
Resumo Fundamento: Alterações no gene da Enzima Conversora de Angiotensina (ECA) podem contribuir para o aumento da pressão arterial e consequentemente para o surgimento de insuficiência cardíaca (IC). O papel do polimorfismo ainda é bastante controverso, sendo necessária sua identificação em pacientes com IC de etiologia chagásica na população

23. β-lactamase-producing Gram-negative bacteria in an intensive care unit in southern Brazil
ABSTRACT The present study evaluated the antimicrobial susceptibility profile, β-lactamase production, and genetic diversity of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. using phenotypic identification, antimicrobial susceptibility testing, and β-lactamase phenotypic detection. Isolates were obtained from patients in an intensive c

24. A SNP in 5′ untranslated region of CD40 gene is associated with an increased risk of ischemic stroke in a Chinese population: a case-control study
Abstract Cluster of differentiation 40 (CD40), the receptor for CD154, is a member of the tumor necrosis factor (TNF) receptor superfamily. Several studies have been conducted to investigate the effect of the CD40 rs1883832 polymorphism on atherosclerotic disease in different population; however, inconsistent results were obtained. In this study, we investig
