The purpose of the paper is to achieve a constrained estimation of process state variables using the anisochronic state observer tuned by the dominant root locus technique. The anisochronic state observer is based on the state-space time delay model of the process. Moreover the process model is identified not only as delayed but also as non-linear. This model is developed to describe a material flow process. The root locus technique combined with the magnitude optimum method is utilized to investigate the estimation process...

INTRODUCTION: Magnesium is an essential cation playing a crucial role in many physiological functions and its imbalance is associated with greater number of pathological situations. Oxidative stress is usually increased due to decreased essential nutrients. Hence, any imbalance of essential nutrients like serum magnesium can significantly play a role in the pathobiology of periodontitis in the presence of diabetes, as diabetes and chronic periodontitis are two chronic diseases that have been biologically linked...

In this paper, we demonstrate a miniature magnetic-force-based, three-axis, AC magnetic sensor with piezoelectric/vibrational energy-harvesting functions. For magnetic sensing, the sensor employs a magnetic-mechanical-piezoelectric configuration (which uses magnetic force and torque, a compact, single, mechanical mechanism, and the piezoelectric effect) to convert x-axis and y-axis in-plane and z-axis magnetic fields into piezoelectric voltage outputs. Under the x-axis magnetic field (sine-wave, 100 Hz, 0.2-3...

The rich bacterial flora of oral cavity is controlled by innate immune response, including antibacterial peptides and among them human neutrophil peptides 1-3 (HNP1-3). The knowledge of the involvement of HNPs in innate and acquired immunity of the periodontium is fragmentary. The aim of the study was to assess alterations in HNP1-3 levels in the gingival crevicular fluid (GCF) of chronic periodontitis patients before and after nonsurgical periodontal therapy. Nineteen patients with chronic periodontitis were qualified to the study...

The bicuspid aortic valve (BAV) is a major risk factor for secondary aortopathy such as aortic dilation. The heterogeneous BAV morphotypes [left-right-coronary cusp fusion (LR), right-non-coronary cusp fusion (RN), and left-non-coronary cusp fusion (LN)] are associated with different dilation patterns, suggesting a role for hemodynamics in BAV aortopathogenesis. However, assessment of this theory is still hampered by the limited knowledge of the hemodynamic abnormalities generated by the distinct BAV morphotypes...

Simvastatin (SMV) is a specific competitive inhibitor of 3-hydroxy-2-methylglutaryl coenzyme A reductase that promotes bone formation. The present clinical trial was designed to investigate the effectiveness of 1.2 mg SMV as a local drug delivery system and as an adjunct to scaling and root planing (SRP) in the treatment of aggressive periodontitis (AgP). A total of 68 intrabony defects from 24 patients with AgP were treated either with 1.2 mg SMV gel or placebo gel. The subjects were randomly assigned to SRP + placebo (group 1; n = 12) or SRP + SMV (group 2; n = 12)...

The location of the heart within the thorax varies significantly between individuals. The resultant diversity of the anatomical cardiac long axis, however, and its determinants, have yet to be systematically investigated. We enrolled 100 consecutive patients undergoing coronary arterial computed tomographic angiography, decomposing the vector of the anatomical cardiac long axis by projecting it to horizontal, frontal, and sagittal planes. The projected vectors on each plane were then converted into three rotation angles using coordinate transformation...

Soft chewable dosage forms are a new approach to improve the compliance of medication for special patient populations. Based on their texture, they are chewed several times before they get swallowed. A suitable dissolution method based on in vivo chewing data was developed. The method covers parts of dissolution within the oral cavity (simulation of chewing) as well as the dissolution of the swallowed bolus within the gastrointestinal tract. Chewing was simulated by the help of a steel tooth assembled to a texture analyzer and wedge gliding on an inclined plane, imitating the occlusal glide...

BACKGROUND: Current technological advances have allowed application of different study designs and techniques for investigation of dental anatomy. Some clinical studies have provided evidence that Cone Beam computed tomography (CBCT) scanning is an important resource in assessment of root canal systems notably to identify MB2 canals in maxillary molars as CBCT scans allow in vivo dental investigation in axial, sagittal and coronal planes simultaneously. The current study was undertaken to detect and evaluate filled/unfilled MB2 canals in endodontically treated, asymptomatic maxillary molars utilizing cone beam computed tomography (CBCT)...

BACKGROUND: Very little data exist on the impact of sex on aortic and arterial anatomy as relevant for transcatheter aortic valve implantation (TAVI). OBJECTIVE: To investigate whether patients with severe aortic stenosis (AS) referred for TAVI display sex-specific differences in aortic root and ilio-femoral artery size. METHODS: In 506 patients referred for pre-procedural CT evaluation before TAVI we performed a detailed assessment of aortic root anatomy: size of the annulus and the sinus of Valsalva (SoV), diameter of the sino-tubular junction (STJ), and distance of the coronary artery ostia to the aortic annulus plane; we also determined the dimensions of aorta, subclavian, and ilio-femoral arteries...

Vertical root fractures (VRFs) usually develop slowly, unnoticed by the patient until clinical signs and symptoms become apparent. In endodontically treated teeth, a VRF is a typical cause for extraction. The objective of the present study was the histologic analysis of VRFs in extracted, endodontically treated premolars and molars. In addition, clinical and radiographic findings of these VRF-affected teeth were retrospectively evaluated. Thirty extracted teeth with a clinically diagnosed VRF were embedded in methylmethacrylate...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has been associated with periodontal disease (PD), and periodontal treatment (PT) has been connected to reduction of lung disease exacerbations. Bronchiectasis has many clinical similarities with COPD but, although it is also a chronic lung disease, to date it has not been studied with relation to PD. The aim of this study is to evaluate whether PT associated with photodynamic therapy (PDT) reduces the number of exacerbations, improves pulmonary function, periodontal clinical parameters and quality of life after 1 year of periodontal treatment follow-up...
