1. Generation of a triple-fluorescent mouse strain allows a dynamic and spatial visualization of different liver phagocytes in vivo
ABSTRACT Resident and circulating immune cells have been extensively studied due to their almost ubiquitous role in cell biology. Despite their classification under the “immune cell department”, it is becoming increasingly clear that these cells are involved in many different non-immune related phenomena, including fetus development, vascular formation,

2. Expression of CD90 and P75NTR stem cell markers in ameloblastomas: a possible role in their biological behavior
Abstract Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evalu

3. Differential expression of hypoxia-inducible factor 1α in non-small cell lung cancer and small cell lung cancer
OBJECTIVES: The aim of this study was to compare the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor in small cell lung cancer and subtypes of non-small cell lung cancer and examine their relationships with clinicopathologic factors, response to treatment and survival. METHODS: We examined samples obtained by bronchial endos

4. Estudo imunohistoquímico da composição estrômato-vascular dos pólipos tonsilares / Immunohistochemical study of the stromal and vascular components of the tonsillar polyps
Tonsillar polyps are nonneoplastic lesions usually composed of a variable amounts of lymphoid, vascular and connective tissues. All are generally assumed to be hamartomatous proliferations but the profile of vascular and connective components has yet to be explored. The vascular system of the tonsils is complex and includes highly specialized structures (i.e

5. Estudo populacional e do potencial invasor da espécie exótica Leucaena leucocephala (Lam.) de Wit em floresta estacional semidecidual
Leucaena leucocephala (Lam.) de Wit is one of the more than 100 species of exotic invasive vascular flora currently registered in Brazil. Planted as hedge at the edge of the semideciduous forest remnant in the IbiporA Forest Park about 25 year ago, it occupieds part of the edge of the remnant, raising the hypothesis that it might invade areas of native fores

6. Diurnal variation of vascular diameter and reactivity in healthy young men
The higher incidence of cardiovascular events in the morning is accompanied by an increased vascular tone. However, there are few published studies designed to evaluate the diurnal variation of vascular and endothelial parameters in healthy subjects. In the present investigation, we evaluated the diurnal variation in brachial artery diameter (BAD), flow-medi

7. Resposta molecular do endotélio pulmonar à exposição aguda de material particulado fino / Molecular response of pulmonary endothelial cells to acute exposure to fine particulate matter
Epidemiological studies establish a clear association between air pollution and increased cardiovascular and respiratory morbidity and mortality. However, the molecular mechanisms underlying the effect of fine particulate matter (PM2,5) are still poorly understood. The aim of this study was to characterize the impact of exposure to PM2,5 on the biology of pu

8. Biossistematica das especies do complexo Anemopaegma arvense (Vell.) Stellf. ex de Souza (Bignoniaceae, Bignonieae) : aspectos anatomicos, citologicos, moleculares, morfologicos e reprodutivos / Biossystematics of the Anemopaegma arvense (Vell.) Stellf. ex de Souza complex (Bignoniaceae, Bignonieae) : anatomical, cytological, molecular, morphological and reproductive aspects
Anemopaegma arvense complex is constituted by species and varieties of difficult delimiting. Taxonomists opinions based upon morphologic features are controversial as to considering them either an only highly polymorphic species or separating them into different taxa. In order to help with the circumscription of such taxa, a biosystematic study was conducted

9. Moraceae Gaudich. de Viçosa, Minas Gerais, Brasil: florística e anatomia foliar de Ficus mexiae Standl / Moraceae Gaudich. of Viçosa, Minas Gerais, Brazil: floristic and leaf anatomy of Ficus mexiae Standl
The present work consists of the floristic study of Moraceae species in Viçosa, of the leaf anatomy, and the histochemical characterization of Ficus mexiae Standl., comparing with the anatomic data in the literature about F. enormis (Miq.) Miq., a species that is similar to F. mexiae. Viçosa is located in the southeastern Brazil, in the state of Minas Gera

10. Relação entre a Síndrome Metabólica, teor de gordura intramiocelular e os níveis plasmáticos da Adiponectina: papel da Rosiglitazona / Relationship between the Metabolic Syndrome, intramyocellular fat and plasma Adiponectin: role of Rosiglitazone
Insulin resistance (IR) is associated with intramyocellular lipid (IMCL) content and low serum adiponectin (ADP) levels. ADP is also involved in muscle fat oxidation but the relationship between them is still controversial. We aimed to further explore the relationship between ADP and IMCL content in non-diabetic adults and the role of rosiglitazone (RSG) in

11. Identificação e caracterização de proteínas modificadas em enxertos de veias safenas humanas arterializadas no modelo ex vivo / Identification and characterization of modified proteins in arterialized human saphenous vein using an ex vivo system
A revascularização cardíaca utilizando a ponte de safena é um procedimento bastante utilizado para restabelecer o fluxo coronariano. Apesar do sucesso deste procedimento, a patência deste enxerto pode chegar a menos de 50% em 10 anos. Atribui-se parte deste insucesso a variações no processo adaptativo à nova condição hemodinâmica, onde o shear str

12. Marcadores de coagulação intravascular disseminada em pacientes graves internados em unidade de terapia intensiva.
Disseminated intravascular coagulation (DIC) is a syndrome caused by systemic activation of clotting factors and it is frequently associated with several diseases such as sepsis, trauma, shock, cancer, and immune and vascular disorders. Sepsis is the main clinical condition associated to DIC. In some cases, the clinical outcome is very fast and severe, and a
