Prevalence of Avian Pathogenic Escherichia coli (APEC) Clone Harboring sfa Gene in Brazil
(Hindawi Publishing Corporation, 2012-01-01)
Escherichia coli sfa+ strains isolated from poultry were serotyped and characterized by polymerase chain reaction (PCR) and amplified fragment length polymorphism (AFLP). Isolates collected from 12 Brazilian poultry farms ...
Correlations between peripheral parasite load and common clinical and laboratory alterations in dogs with visceral leishmaniasis
(2016-09-15)
Intensity of peripheral parasite infection has an important role in the transmission of Leishmania spp. from one host to another. As parasite load quantification is still an expensive procedure to be used routinely in ...
Molecular and phenotypic characterisation of Mycobacterium tuberculosis resistant to anti-tuberculosis drugs
(International Union Against Tuberculosis and Lung Disease, 2013-08)
SETTING: Dr Cetrángolo Hospital, Buenos Aires, Argentina. OBJECTIVES: To characterise drug-resistant (DR), multidrug-resistant (MDR-) and extensively drug-resistant (XDR-) Mycobacterium tuberculosis isolates, and identify ...
Annexin A1 subcellular expression in laryngeal squamous cell carcinoma
(Wiley-Blackwell Publishing, Inc, 2008-12-01)
Annexin A1 (ANXA1) is a soluble cytoplasmic protein, moving to membranes when calcium levels are elevated. ANXA1 has also been shown to move to the nucleus or outside the cells, depending on tyrosine-kinase signalling, ...
The BENEFIT trial: testing the hypothesis that trypanocidal therapy is beneficial for patients with chronic Chagas heart disease
(Instituto Oswaldo Cruz, Ministério da Saúde, 2009)
Among the pathophysiological derangements operating in the chronic phase of Chagas disease, parasite persistence is likely to constitute the main mechanism of myocardial injury in patients with chronic chagasic cardiomyopathy. ...
Polymorphisms and Haplotypes in the Interleukin-4 Gene are Associated With Chronic Periodontitis in a Brazilian Population
(Amer Acad Periodontology, 2010-03-01)
Background: Some haplotypes in the interleukin-4 (IL4) gene were reported to influence IL-4 cytokine production and were associated with inflammatory diseases. Association studies focusing on IL4 gene polymorphisms and ...

(MARY ANN LIEBERT INC, 2011)
During 2010, 15 adult ticks, identified as Amblyomma cajennense, were collected from horses in Cahuita and Turrialba districts, whereas 7 fleas, identified as Ctenocephalides felis, were collected from a dog in San Jose ...
High Iodine Concentration Attenuates RET/PTC3 Oncogene Activation in Thyroid Follicular Cells
(MARY ANN LIEBERT INC, 2009)
Background: Papillary thyroid carcinoma (PTC) is frequently associated with a RET gene rearrangement that generates a RET/PTC oncogene. RET/PTC is a fusion of the tyrosine kinase domain of RET to the 50 portion of a different ...
Fluoxetine Inhibits Inflammatory Response and Bone Loss in a Rat Model of Ligature-Induced Periodontitis
(Amer Acad Periodontology, 2012-05-01)
Background: Fluoxetine, a selective serotonin reuptake inhibitor, has been found recently to possess anti-inflammatory properties. The present study investigates the effects of fluoxetine on inflammatory tissue destruction ...
