Although different nanosized materials, including quantum dots (QDs), are intended to be used for biomedical applications, their interactions with microvessels and their inflammatory potential are largely unknown. In this in vivo study we report that leukocyte recruitment is modulated in the presence of quantum dots. We found that the surface chemistry of(More)
UNLABELLED Oral squamous cell carcinoma (OSCC) is one of the most common malignances. In epithelial-mesenchymal transition (EMT), epithelial cells switch to mesenchymal-like cells exhibiting high mobility. This migratory phenotype is significant during tumor invasion and metastasis. OBJECTIVE The aim of this study is to evaluate the expression of the EMT(More)
Physical activity evokes well-known adaptations in the cardiovascular system. Although exercise training induces cardiac remodeling, whether multipotent stem cells play a functional role in the hypertrophic process remains unknown. To evaluate this possibility, C57BL/6 mice were subjected to swimming training aimed at achieving cardiac hypertrophy, which(More)
The behavior of quantum dots (QDs) in the microvasculature and their impact on inflammatory reactions under pathophysiological conditions are still largely unknown. Therefore, we designed this study to investigate the fate and effects of surface-modified QDs in postischemic skeletal and heart muscle. Under these pathophysiological conditions, amine-modified(More)
The aim of the present study was to assess the effects of an anticholinesterase agent, pyridostigmine bromide (Pyrido), on experimental chronic Chagas heart disease in mice. To this end, male C57BL/6J mice noninfected (control:Con) or chronically infected (5 months) with Trypanosoma cruzi (chagasic:Chg) were treated or not (NT) with Pyrido for one month. At(More)
The last decade has brought a comprehensive change in our view of cardiac remodeling processes under both physiological and pathological conditions, and cardiac stem cells have become important new players in the general mainframe of cardiac homeostasis. Different types of cardiac stem cells show different capacities for differentiation into the three major(More)
BACKGROUND Oral squamous cell carcinoma (OSCC) is one of the most prevalent cancers worldwide. Laminin-5 gamma 2 chain (laminin-5 γ2) is a protein associated to a migratory phenotype in epithelial neoplastic cells. Stromal myofibroblasts also play a significant role in tumor invasion, due to its ability to modify the extracellular matrix. Tumor budding is a(More)
Mucosal leishmaniasis is a chronic infection that affects the upper respiratory tract and/or the oral mucosa caused by Leishmania protozoan parasites. We present two cases of oral leishmaniasis and discuss the different diagnostic strategies and treatment. In both cases, the patients were male, 60 and 94 years of age, and presented with lesions on the soft(More)
To explore information available in the literature about the possible benefits resulting from physical activity (PA) in non-risky pregnant women, repercussion on maternal organism, fetal development, and on long-term offspring health. Critical narrative review using online databases. Through critical discussion of studies focused on PA practiced during(More)
