Estudo Prospectivo Referente aos Principais Factores de Risco de Patologia Card...

Introdução: é actualmente consensualmente reconhecido que a aterosclerose tem a sua origem na idade pediátrica ainda que as expressões clínicas da doença cardio-cérebro-vascular se manifestem apenas na idade adulta. Entre os seus principais factores de risco apontam-se entre outros, a obesidade, a hipertensão e um perfil lipídico sérico adverso. Tais factores de risco evidenciam uma notória estabilidade relativ...

Cianose no pequeno lactente – desafio diagnóstico

Human adipose stem cells cell sheet constructs impact epidermal morphogenesis i...

Among the wide range of strategies to target skin repair/regeneration, tissue engineering (TE) with stem cells at the forefront, remains as the most promising route. Cell sheet (CS) engineering is herein proposed, taking advantage of particular cell-cell and cell-extracellular matrix (ECM) interactions and subsequent cellular milieu, to create 3D TE constructs to promote full-thickness skin wound regeneration. ...

Development of a quasi-dry electrode for EEG recording

The present work reports on the development of a novel polymer-based electrode prototype for electroencephalography (EEG). The new electrode concept lies between the classic “wet” and “dry” electrodes, allowing addressing most of their drawbacks, while keeping the advantages of both. A localized skin hydration effect at the electrode/scalp contact point is achieved by the release of a small amount of a moisturi...

Persistent primary hyperparathyroidism: an uncommon location for an ectopic gla...

Primary hyperparathyroidism (PHPT) is a common endocrine disorder that mainly affects middle-aged women. Patients are usually asymptomatic. The disease might be ascribable to hyperplasia, carcinoma, and single or multiple adenomas. PHPT may be sporadic or familial, the latter comprising multiple endocrine neoplasia type 1 or 2A, familial benign hypocalciuria hypercalcemia, and hyperparathyroidism-jaw tumor synd...

Influence of tool shoulder geometry on properties of friction stir welds in thi...

The aim of this work is to study the influence of the shoulder geometry on friction stir welding of 1 mm-thick copper-DHP plates. The welds were produced using three different shoulder geometries, flat, conical and scrolled, and varying the rotation and traverse speeds of the tool. The flat shoulder tool proved to be inadequate for performing welds, because many defects were produced for all welding conditions....

Influence of L-cysteine, oxygen and relative humidity upon survival throughout ...

The survival rates of Lactobacilus acidophilus Ki, Lactobacillus paracasei L26 and Bifidobacterium animalis BB-12 were studied after whey protein microencapsulation via spray-drying, with or without L-cysteine- HCl, and storage up to 6 months at 5 C and 22 C, with variation in relative air humidity and oxygen levels. Lb. paracasei L26 was the least susceptible to storage conditions: above 106 cfu g 1 were rec...

Cardiac gene expression and systemic cytokine profile are complementary in a mu...

After myocardial infarction (MI), activation of the immune system and inflammatory mechanisms, among others, can lead to ventricular remodeling and heart failure (HF). The interaction between these systemic alterations and corresponding changes in the heart has not been extensively examined in the setting of chronic ischemia. The main purpose of this study was to investigate alterations in cardiac gene and syst...
