Disfunção Plaquetária Induzida pelo Darunavir em Doente com Infeção VIH-1

As plaquetas desempenham um papel importante na hemóstase primária e a sua disfunção pode resultar em manifestações hemorrágicas, principalmente, mucocutâneas. Apesar das manifestações serem, na maioria das vezes, de gravidade ligeira a moderada, os doentes com disfunção plaquetária podem constituir um desafio hemostático, quando submetidos a procedimentos invasivos. As causas podem ser hereditárias ou adquirid...

INR vs Doseamento de Fator X Cromogénico e Fator II: C em Doentes com Síndrome ...

Os fatores dependentes da vitamina K podem estar diminuídos de modo variável, sendo o Fator (F) II e o FX os principais determinantes relativamente ao efeito antitrombótico. A ligação dos anticorpos antifosfolipídicos aos fosfolípidos pode causar um falso prolongamento do tempo de protrombina (TP) em doentes com anticoagulante lúpico. Correlacionámos os resultados da razão normalizada internacional (INR) – usan...

Bearing My Heart: The Role of Extracellular Matrix on Cardiac Development, Home...

The extracellular matrix (ECM) is an essential component of the heart that imparts fundamental cellular processes during organ development and homeostasis. Most cardiovascular diseases involve severe remodeling of the ECM, culminating in the formation of fibrotic tissue that is deleterious to organ function. Treatment schemes effective at managing fibrosis and promoting physiological ECM repair are not yet in r...

Biotechnology Applied to Cosmetics and Aesthetic Medicines

Biotechnology uses microorganisms and/or enzymes to obtain specific products through fermentative processes and/or genetic engineering techniques. Examples of these products are active ingredients, such as hyaluronic acid, kojic acid, resveratrol, and some enzymes, which are used in skin anti-aging products. In addition, certain growth factors, algae, stem cells, and peptides have been included in cosmetics and...

Neonatal Apex Resection Triggers Cardiomyocyte Proliferation, Neovascularizatio...

So far, opposing outcomes have been reported following neonatal apex resection in mice, questioning the validity of this injury model to investigate regenerative mechanisms. We performed a systematic evaluation, up to 180 days after surgery, of the pathophysiological events activated upon apex resection. In response to cardiac injury, we observed increased cardiomyocyte proliferation in remote and apex regions,...

Sudden Cardiac Death in Young Adult

Cardiovascular disease represents one of the most important public health problem in the Western countries, with sudden cardiac death (SCD) being the most common cause of death in adults under 65 years of age. The objective of the present study is to evaluate the leading causes of SCD in young adults who died suddenly in Northern Portugal between 2007 and 2012. This study included 288 cases of 20- to 45-year-ol...
