Protease/anti-protease imbalance is the main pathogenic mechanism of emphysema and protease inhibitors have been recognized as potential molecules to treat the disease conditions. In this work the rBmTI-6 first domain (rBmTI-6-D1), a recombinant Kunitz-type serine proteinase inhibitor, was used to verify its effect in prevention or minimization of PPE-induced emphysema in mice. C57BL/6 mice were submitted to a PPE-induced emphysema model and treated with rBmTI-6-D1 before the emphysema development. We showed that the rBmTI-6-D1 treatment was sufficient to avoid the loss of elastic recoil, an effective decrease in alveolar enlargement and in the number of macrophages and lymphocytes in bronchoalveolar lavage fluid...

There have been significant efforts toward the development of more efficient vaccines for animal health. A strategy that may be used to improve vaccine efficacy is the use of probiotics. Bovine herpesvirus 5 (BoHV-5) is an example of an important animal pathogen for which vaccines have provided only limited protection. In this study, we examined the use of the probiotics Bacillus toyonensis and Saccharomyces boulardii as a potential immune modulator to improve vaccine efficiency. Thirty, 5-month-old lambs were randomly grouped in three lots of 10 each and vaccinated at days 0, 21 and 42 of the experiment...

The best hypothesis to explain Sudden Infant Death Syndrome (SIDS) pathogenesis is offered by the "triple risk model", which suggests that an interaction of different variables related to exogenous stressors and infant vulnerability may lead to the syndrome. Environmental factors are triggers that act during a particular sensible period, modulated by intrinsic genetic characteristics. Although literature data show that one of the major SIDS risk factors is smoking exposure, a specific involvement of molecular components has never been highlighted...

Systemic inflammation is emerging as a significant driver of cognitive decline in the aged and vulnerable brain. In sepsis survivors animals low-grade brain inflammation occurs, suggesting that sepsis is able to induce in microglia a primed-like state. The purpose of this study is to analyze the role of sepsis-induced brain inflammation in the progression of the physiological process of brain aging. Wistar rats 2month-old were subjected to sepsis and 60 and 90days after were submitted to the new object recognition test and brain was removed to the determination of cytokines, myeloperoxidase (MPO) activity, amyloid-beta peptide (Aβ) and immunohistochemistry markers of microglial activation...

BACKGROUND: Hereditary hemochromatosis (HH) encompasses a group of autosomal recessive disorders mainly characterized by enhanced intestinal absorption of iron and its accumulation in parenchymal organs. HH diagnosis is based on iron biochemical and magnetic resonance imaging (MRI) assessment, and genetic testing. Questionnaires, such as SF-36 (short form health survey), have been increasingly used to assess the impact of diseases on the patient's quality of life (QL). In addition, different genotypes are identified as results of genetic tests in patients with suspected primary iron overload...

A spectrum of vascular complications can be seen in pediatric liver transplant patients, including occlusion and hemodynamically significant narrowing of the vessels that provide inflow to or outflow from the graft. Intraoperative Doppler ultrasound (US) has the potential benefit of identifying vascular complications in pediatric liver transplant patients prior to abdominal closure. Importantly, intraoperative Doppler US can be used as a problem-solving tool in situations such as position-dependent kinking of the portal or hepatic veins, or in suspected vasospasm of the hepatic artery...
