to determine graft patency, limb salvage, and patient survival following infrainguinal bypass grafting in patients with end-stage renal disease (ESRD).studies published from 1987 through 2000 were identified from the PUBMED database and pertinent original articles. Sixteen studies were found that used survival analysis to report the outcomes of interest. Two investigators independently extracted the data from standard life-tables, survival curves and texts. A new method was developed for meta-analysis ...

Although bioresorbable vascular stents (BVS) have emerged as a promising alternative to overcome complications of metallic stents, adverse outcomes of BVS demand further improvements. The development of photocrosslinkable polyesters, such as methacrylated poly(dodecanediol citrate) (mPDC) for use in light-assisted 3D printing technologies, brought new perspectives for the fabrication of BVS. In line with this approach, the knowledge of the pro-endothelial and anti-thrombotic actions of nitric oxide ( ...

This study evaluated the influence of Tanzania-grass sward height (30, 50, 70 and 90 cm) on the morphological characteristics of the canopy, grazing behavior and forage intake by adult Anglo Nubian female goats. A completely randomized experimental design was employed, with two replicates in space and two replicates in time. Six animals were used to assess the grazing behavior, and four, the ingestion process. The rise in sward height increased the forage and leaf mass, the percentages of stem and ...

Background Pleural tuberculosis (PlTB) is the most common extrapulmonary manifestation of this infectious disease which still presents high mortality rates worldwide. Conventional diagnostic tests for PlTB register multiple limitations, including the lack of sensitivity of microbiological methods on pleural specimens and the need of invasive procedures such as pleural biopsy performance. In this scenario, the search for biological markers on pleural fluid (PF) has been the target of several studies ...

A method for direct in situ thickness measurements of ultra-thin soft polymer films is presented in which an atomic force microscope (AFM) tip is used to create a furrow in the film, whereby the thickness is determined by scanning the sample across the furrow with the AFM. The sample does not need to be moved since the scratching and the measurements are performed with the same apparatus. This `furrow method' is applied to layer-by-layer polymer/polyelectrolyte ultra-thin films onto hydrophilic glass ...

The application of thin films as coating on several surfaces has been one of the major factors responsible for technological advances. Additive Manufacturing is used to define a set of technologies that have the building of 3D physic prototypes as a common characteristic. In this work we have studied the properties of Polyamide 12 samples obtained by rapid prototyping after coating with different metal transitions by sol–gel methodology. The sols were prepared with silicon, vanadium, titanium, or ...

The induction motor plays a key role in many industrial sectors, primarily due to its robustness and low cost. When the load coupled to the motor axis requires speed control, some of the drive and control strategies are based on the estimated axis speed of the motor. The direct measurement of this quantity reduces its robustness and increases the driver implementation cost. This paper proposes an alternative methodology for estimating the speed of a three phase induction motor driven by a voltage ...

It is well-known that performance of photovoltaic (PV) systems can be severely deteriorated when PV arrays are subjected to partial shading conditions, once the traditional techniques used for maximum power point tracking (MPPT) could not operate in the global maximum power point (GMPP). Thus, to overcome this problem and achieve the GMPP, four MPPT techniques bio-inspired in the grey wolf optimisation (GWO) are presented. These MPPT techniques, which are named as GWO, GWO-Beta, GWO-IC (Incremental Conductance), ...

The samples were obtained using p-phenylenediamine and urea (N–CdotR), and citric acid and ammonium hydroxide (N–CdotB) as precursors, respectively. The structural and morphological properties of the N-Cdots were investigated using TEM, Raman spectroscopy and FTIR. The nanoparticles of both samples exhibited a large number of hydrophilic surface groups. ...

Insect pollination services substantially enhance global major crops in terms of fruit quantity and potentially quality. Even Citrus crops, which have been supported by broad breeding programs and well-established agrotechniques, depend on pollinators to achieve high yields. In this study, the effects of pollination services on the production of 'Lee' and 'Nova' tangelos were experimentally assessed in north-eastern Brazil. The associated flower visitors were surveyed and the visitation pattern on ...

Land-use and land-cover (LULC) changes are major drivers of biodiversity loss in semi-arid regions, such as the Caatinga biome located in the Northeast of Brazil. We investigated landscape dynamics and fragmentation in an area of the São Francisco Valley in the Brazilian Caatinga biome and measured the effect of these dynamics on ecological, functional and structural connectivity over a 33-year period (1985–2018). We calculated landscape connectivity indices based on graph theory to quantify the effect ...

Leprosy reactions are responsible for incapacities in leprosy and represent the major cause of permanent neuropathy. The identification of biomarkers able to identify patients more prone to develop reaction could contribute to adequate clinical management and the prevention of incapacities.
