1. Root canal dressings for revascularization influence in vitro mineralization of apical papilla cells
Abstract Endodontic revascularization is based on cell recruitment into the necrotic root canal of immature teeth after chemical disinfection. The clinical outcome depends on the ability of surviving cells from the apical tissue to differentiate and promote hard tissue deposition inside the dentinal walls. Objective To investigate the effect of calcium hyd

2. Porcine circovirus 2 (PCV2) increases the expression of endothelial adhesion/junction molecules
Abstract Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus disease, a complex multisystem syndrome in domestic pigs. Despite the significant economic losses caused by porcine circovirus disease, the mechanisms of pathogenesis underlying the clinical findings remain largely unclear. As various reports have highlighted the p

3. Sexual transmission of human T-cell lymphotropic virus type 1
Human T-cell lymphotropic virus type 1 (HTLV-1) is endemic in many parts of the world and is primarily transmitted through sexual intercourse or from mother to child. Sexual transmission occurs more efficiently from men to women than women to men and might be enhanced by sexually transmitted diseases that cause ulcers and result in mucosal ruptures, such as

4. The putative role of ovary removal and progesterone when considering the effect of formaldehyde exposure on lung inflammation induced by ovalbumin
OBJECTIVE: Formaldehyde exposure during the menstrual cycle is known to affect the course of allergic lung inflammation. Because our previous data demonstrated that formaldehyde combined with an ovariectomy reduced allergic lung inflammation, we investigated the putative role of ovary removal and progesterone treatment when considering the effect of formald

5. Chemokines and chemokine receptors expression in the lesions of patients with American cutaneous leishmaniasis
American cutaneous leishmaniasis (ACL) presents distinct active clinical forms with different grades of severity, known as localised (LCL), intermediate (ICL) and diffuse (DCL) cutaneous leishmaniasis. LCL and DCL are associated with a polarised T-helper (Th)1 and Th2 immune response, respectively, whereas ICL, or chronic cutaneous leishmaniasis, is associat

6. Papel dos leucócitos na fisiopatologia da anemia falciforme / Role of leukocytes in sickle cell anemia pathophysiology
Sickle Cell Disease (SCD) is a disorder of hemoglobin synthesis, caused by a point mutation, and resulting in the production of abnormal sickle hemoglobin, HbS. The consequence of low oxygen levels is HbS polymerization, which is responsible for the vaso-occlusive phenomenon that is the hallmark of the disease. SCD is a chronic inflammatory disease character

7. Efeito de ExoU na ativação de NF-κB e na secreção de IL-8 por células humanas infectadas por Pseudomonas aeruginosa / Effect of Exou on the activation of the NF-κB and the secretion of the IL-8 in human cells infected with Pseudomonas
ExoU, a cytotoxin produced by the opportunistic pathogen Pseudomonas aeruginosa that is translocated into host cell cytosol by the type three secretory system, has been associated with severity of acute infections. We have previously described the potent ExoU proinflammatory activity, which accounts for a market recruitment of neutrophils to infected tissues

8. Participação das selectinas nas interações entre células angiogênicas da medula óssea e endotélio de músculos isquêmicos de membros inferiores em modelo murino.
The stimulation of vascular growth by angiogenic stem cells transplantation is a promising alternative for the treatment of PAD. Adhesive mechanisms governing progenitor/stem cell trafficking through the microcirculation of ischemic muscles are broadly unknown. The aim of this work was to evaluate the involvement of selectins on interactions between transpla

9. Dermatan sulfate reduces monocyte chemoattractant protein 1 and TGF-β production, as well as macrophage recruitment and myofibroblast accumulation in mice with unilateral ureteral obstruction
Selectins play an essential role in most inflammatory reactions, mediating the initial leukocyte-rolling event on activated endothelium. Heparin and dermatan sulfate (DS) bind and block P- and L-selectin function in vitro. Recently, we reported that subcutaneous administration of DS inhibits colon inflammation in rats by reducing macrophage and T-cell recrui

10. Short-term exposure of mice to cigarette smoke and/or residual oil fly ash produces proximal airspace enlargements and airway epithelium remodeling
Chronic obstructive pulmonary disease (COPD) is associated with inflammatory cell reactions, tissue destruction and lung remodeling. Many signaling pathways for these phenomena are still to be identified. We developed a mouse model of COPD to evaluate some pathophysiological mechanisms acting during the initial stage of the disease. Forty-seven 6- to 8-week-

11. Evidence for eosinophil recruitment, leukotriene B4 production and mast cell hyperplasia following Toxocara canis infection in rats
It is well known that eosinophilia is a key pathogenetic component of toxocariasis. The objective of the present study was to determine if there is an association between peritoneal and blood eosinophil influx, mast cell hyperplasia and leukotriene B4 (LTB4) production after Toxocara canis infection. Oral inoculation of 56-day-old Wistar rats (N = 5-7 per gr

12. Regulation of protein synthesis and the role of eIF3 in cancer
Maintenance of cell homeostasis and regulation of cell proliferation depend importantly on regulating the process of protein synthesis. Many disease states arise when disregulation of protein synthesis occurs. This review focuses on mechanisms of translational control and how disregulation results in cell malignancy. Most translational controls occur during
