In this paper, we deal with two important issues in relation to modular recon gurable manipulators, namely, the determination of the modular assembly con guration optimally suited to perform a speci c task and the synthesis of fault tolerant systems. We present a numerical approach yielding an assembly con guration that satis es four kinematic task requirements: reachability, joint limits, obst...

Celiac disease (CD) is a common autoimmune disorder characterized by an immune response to ingested gluten and has a strong HLA association with HLA-DQ2 and HLA-DQ8 molecules, but human HLA-DQ risk factors do not explain the entire genetic susceptibility to gluten intolerance. CD is caused by the lack of immune tolerance (oral tolerance) to wheat gluten. In this sense, the expression of soluble...

OBJECTIVE To investigate the modulatory effects that dynamic hyperinflation (DH), defined as a reduction in inspiratory capacity (IC), has on exercise tolerance after bronchodilator in patients with COPD. METHODS An experimental, randomized study involving 30 COPD patients without severe hypoxemia. At baseline, the patients underwent clinical assessment, spirometry, and incremental cardiopulm...

Thirty three patients with definite ankylosing spondylitis (AS) were examined to establish the relation between restriction of chest expansion, limitation of lung function, and working capacity or exercise tolerance. As in previous studies there was a significant association between chest expansion and lung vital capacity. There was also a significant association between vital capacity and exer...

Although evidences indicate that C-reactive protein (CRP) levels are independent predictors of type 2 diabetes (DM), some studies either did not support this association or examine it extensively throughout the stages of glucose tolerance. In a cross-sectional population-based survey, we investigated the relation between CRP and the risk of newly diagnosed impaired glucose tolerance (IGT), and ...

The pre-absorptive cephalic phase of insulin secretion is elicited during the first ten min of a meal and before glucose levels rise. Its importance for insulin release during the post-absorptive phase has been well documented in animals but its presence or importance in man has become increasingly controversial. We here examined the presence of an early cephalic phase of insulin release in 31 ...

We isolated and characterized As-resistant endophytic bacteria (AEB) from two arsenic hyperaccumulators. Their plant growth promoting traits and the relation between As tolerance and transformation were evaluated. A total of 41 and 33 AEB were isolated from Pteris vittata (PV) and Pteris multifida (PM) respectively. PV AEB represented 2genera while PM AEB comprised of 12 genera, with Bacillus s...

In this paper, on the basis of studying the limitations of the basic rough set model, we present Tolerance Information Systems, which is based on a family set of tolerance relations between objects when given a set of tolerance relations. The model inherits most of the characteristics of the basic model of rough set; and they also have a better effect of approximation classification. Based on t...

Objective: To ascertain the prevalence of abnormal glucose metabolism in patients with coronary artery disease (CAD) but no previous diagnosis of diabetes mellitus (DM) and to examine the relation between the severity of CAD and responses of glucose and insulin to the glucose tolerance test. Methods and results: Abnormalities of glucose metabolism and insulin response were analysed in 144 patie...

The aim of this study was to investigate a possible relation between EPS production and resistance to bile salts and tolerance to low pH. Eight strains which produced the highest and lowest amount of EPS (16211mg/l) were selected among 54 bacteria isolated from yogurt. Additionally, they were tested for resistance to bile salts (0.15, 0.3 %) and tolerance to low pH (2.0-3.0). After treatment wi...
