Control of the single atom/nanoparticle ratio allows preparation highly active Pd/C hydrogenation catalysts integrating ultra-rational use Pd.

This study investigated the relationship between fear of falling (FOF) and qualitative and quantitative postural control in Parkinson's disease (PD). Fifty-eight nondemented PD patients were studied along with age-matched healthy controls. The degree of FOF was estimated using the Activities-specific Balance Confidence scale. Qualitative postural control was evaluated using a component of the U...

background and aims. a combination of guided tissue regeneration (gtr), bovine porous bone mineral (bpbm), and platelet rich plasma has been already applied for the regeneration of intrabony defects. the aim of this study was to determine the role of plasma rich in growth factor (prgf) alone in the periodontal regeneration of intrabony defects in humans as compared with bpbm/gtr technique. mate...

In order to improve the speed and accuracy of the trajectory tracking control for 3R plane robot, a PD iterative self-learning control algorithm is proposed based on the PD iterative control algorithm. The error of target value and the actual value of this iteration is introduced into the PD learning gain to make the PD learning gain becomes a function of the error and to achieve the effect of ...

This paper constructs a relationship between attitude and translational movement of a quadrotor, and presents a PD logic tracking control design algorithm capable of not only stabilizing attitude but also tracking a desired trajectory accurately. In contrast to conventional flight control systems, the artificial inner/outer-loop structure is eliminated via using a third-order time optimal track...

In this paper, analytical structures of TITO (two-input two-output) Mamdani fuzzy PI/PD controllers are investigated with respect to conventional PI/PD control and variable gain control. Components of the fuzzy controllers include two input fuzzy sets for each input variable, five singleton output fuzzy sets for each output variable, 16 fuzzy rules, product AND fuzzy logic operator, the Mamdani...

Recent genome-wide association studies identified 11 risk loci in different populations of familial and sporadic Parkinson's disease (PD) patients. Few loci have been verified in different European and Asian populations. We also validated 2 new single-nucleotide polymorphisms, rs947211 and rs823144, in PARK16 to explore their association with susceptibility to PD in the Xinjiang Uygur and Han p...

STUDY OBJECTIVES Aspiration pneumonia, a leading cause of death in patients with Parkinson disease (PD), usually occurs at the advanced stages of the disease. We investigated both motor and sensory components of cough and induced-sputum substance P (SP) concentrations in patients with early and advanced stages of PD to assess whether cough efficacy is impaired in PD. SUBJECTS Fifteen female p...

Parkinson's disease (PD) includes motorial and non-motorial features, both negatively influencing patients’ life quality. While motor symptoms are well recognized and described, non motor symptoms are becoming a more recent focus of interest and research. This review aims to give an updated information about non-motor symptoms in PD. It comprehends three sections: 1) cognitive dysfunctions, 2) ...
