Previous data has shown that patients in the indeterminate form of Chagas disease may present myocardial fibrosis as shown on through magnetic resonance imaging (MRI). However, there is little information available regarding the degree of severity of myocardial fibrosis in these individuals. This variable has the potential to predict the evolution of Chagas' disease into its cardiac form.To describe the frequency and extent of myocardial fibrosis evaluated using an MRI in patients in the indeterminate ...

Poly(lactic acid) (PLA) electrospun membranes were obtained by electrospinning and characterized by scanning electron microscopy (SEM) and thermal analysis. The polymer membranes showed a random fiber distribution with a mean diameter of 1 μm (±300 nm). Differential scanning calorimetry (DSC) experiments showed that the membranes had a glass transition, cold crystallization, and melting temperatures of 54, 90, and 151°C, respectively. The kinetic study of thermal degradation of PLA under a nitrogen atmosphere ...

Chitosan fiber mats were successfully processed by electrospinning. The as-spun fiber mats were neutralized with ethanol and cross-linked with glutaraldehyde. A decrease of the fiber average diameter from 243 ± 43 nm down to 215.53 nm was observed for the neutralized and cross-linking chitosan membrane. It was found that the processing conditions do not alter the initial deacetylation degree of the polymer. Polymer crystallinity index showed a decrease from 61% for the Protasan material down to 17% ...

Hydrolytic degradation of electrospun mats of poly(l-lactic acid), PLLA, as a function of crystallinity and fiber diameter has been studied. The degradation in a saline phosphate buffer solution (PBS) up to 20 weeks produced a slight decrease in the sample mass but a clear decrease of the polymer average molecular weight in the amorphous fibers. This effect decreases as crystallinity increases. It is important for applications that morphological characteristics of the membranes such as average fiber ...

Abstract: Based on a companion publication that introduces the theoretical foundations, this paper describes the implemented architecture for formation control of the upper segment vehicles of the MORPH project. We highlight the necessary modifications and additional elements, mainly in terms of control and estimation, to allow for the implementation in real vehicles. We illustrate the performance of the system with results from sea trials in Lisbon and in the Azores, with a number of heterogeneous ...

There is increasing attention on the complex interactions occurring between schistosome parasites and their hosts. However, little is known about the occurrence, epidemiology, and mechanisms of schistosomiasis-associated infertility. In this article, we argue that an in-depth understanding of the interplay between parasites and the host endocrine system may significantly enhance current knowledge of infertility in infected individuals. We discuss the basic hormonal mechanisms that may lead to the ...

Poly(hydroxybutyrate) (PHB) obtained from sugar cane waste was dissolved in a blend of chloroform and dimethylformamide (DMF) and electrospun at 40°C. By adding DMF to the solution, the electrospinning process for the PHB polymer becomes more stable, allowing complete polymer crystallization during the jet travelling between the tip and the grounded collector. The influence of processing parameters on fiber size and distribution was systematically studied. It was observed that an increase of tip inner ...

Machado–Joseph disease (MJD) is a late-onset neurodegenerative disorder caused by a polyglutamine (polyQ) expansion in the ataxin-3 protein. We generated two transgenic mouse lineages expressing the expanded human ataxin-3 under the control of the CMV promoter: CMVMJD83 and CMVMJD94, carrying Q83 and Q94 stretches, respectively. Behavioral analysis revealed that the CMVMJD94 transgenic mice developed motor uncoordination, intergenerational instability of the CAG repeat and a tissue-specific increase ...

<b><i>Objectives:</i></b> Chagas cardiomyopathy has worse long-term outcomes than other cardiomyopathies. A biomarker strategy to refer subjects for noninvasive cardiac imaging may help in the early identification of cardiac damage in subjects with Chagas disease. Galectin-3 (Gal-3) is a mediator of cardiac fibrosis shown to be upregulated in animal models of decompensated heart failure. Here we assessed the correlation of Gal-3 with myocardial fibrosis in patients with Chagas ...

The incorporation of MWCNT into the composite increased the tensile strength and Young's modulus by up 5 and 2%, respectively. At low temperature, the incorporation of the nanoparticles improved the fatigue strength of the laminates by 15%. The shear strength results obtained ...

Multifunctionalized 2‐pyrrolinones were synthesized from the formal aza‐[3 + 2] cycloaddition reaction of acyclic enaminones and diphenylcyclopropenone. For primary enaminones, solventless reaction under microwave heating was developed. On the other hand, catalysis by Bi 2 O 3 under conventional heating was the more suitable strategy when secondary enaminones were employed. These conditions allowed the synthesis of a set of 2‐pyrrolinones with two vicinal phenyl substituents, which were evaluated ...

One of the most challenging issues of chronic Chagas disease is to provide earlier detection of heart involvement. Two-dimensional speckle tracking (2-D ST) echocardiography, a new imaging modality with useful applications in several cardiac diseases, has been validated for subjects with myocardial infarction against cardiac magnetic resonance (CMR). Here we hypothesize that the longitudinal global strain (LGS) has an incremental value to ejection fraction for predicting myocardial fibrosis in subjects ...
