interleukin-1β (il-1β) is one of the most important cytokines which seems to have an important role in the inflammatory process in gingival and peri-implant tissues. the aim of this split-mouth study was to investigate the relationship between the concentration of il-1β in gingival crevicular fluid (gcf) and peri-implant crevicular fluid (picf) and clinical parameters such as plaque index (pi),...

The limitations of conventional model-based control mechanisms for flexible manipulator systems have stimulated the development of intelligent control mechanisms incorporating fuzzy logic and neural networks. Problems have been encountered in applying the traditional PD-, PI-, and PID-type fuzzy controllers to flexible-link manipulators. A PD-PI-type fuzzy controller has been developed where th...

It is meaningful for researching on monitoring and forecasting technology of slope stability to prevent landslide disasters, especially in the water system fields. Based on the mechanical principle of interaction among sliding mass, sliding bed and monitoring cable, a new type of energy absorbing cable (called Large Deformation Cable with Constant Resistance) which can have 2000mm deformation w...

Abstract: In this paper, PD-like visual servoing is modified in two ways: a sliding-mode observer is applied to estimate the joint velocities, and a RBF neural network is used to compensate the unknown gravity and friction. Based on Lyapunov method and input--to-state stability theory, we prove that PD-like visual servoing with the sliding mode observer and the neuro compensator is robust stabl...

 Abstract Introduction: Periodontitis is a chronic inflammatory disease with the destruction of tooth supporting structures. The aim of this study was to evaluate the effect of green tea mouthwash compared to chlorohexidine (CHX) mouthwash, as adjuncts to scaling and root planning (SRP), on clinical parameters of subjects with chronic periodontitis.Materials and Methods:A double-blinded rand...

We examined the movement of an actin filament sliding on a mixture of normal and genetically modified myosin molecules that were attached to a glass surface. For this purpose, we used a Dictyostelium G680V mutant myosin II whose release rates of Pi and ADP were highly suppressed relative to normal myosin, leading to a significantly extended life-time of the strongly bound state with actin and v...

In this study, we demonstrated a Monte Carlo simulation to model finger structure and calculate the intensity of photons passing through tissues, in order determine optimal angular separation between photodetector (PD) light-emitting diode (LED), detect SpO2. Furthermore, our was used suggest mirror-coated ring-type pulse oximeter improve sensitivity by up 80% power consumption 65% compared mir...

We investigated the negative effect of type I IFN (IFN-I) on the priming of specific CD8 T cell immunity. Priming of murine CD8 T cells is down-modulated if Ag is codelivered with IFN-I-inducing polyinosinic:polycytidylic acid (pI/C) that induces (NK cell- and T/B cell-independent) acute changes in the composition and surface phenotype of dendritic cells (DC). In wild-type but not IFN-I recepto...

The vertebrate adenohypophysis forms as a placode at the anterior margin of the neural plate, requiring both hedgehog (Hh) and fibroblast growth factor (Fgf) mediated cell-cell signaling for induction and survival of endocrine cell types. Using small molecule inhibitors to modulate signaling levels during zebrafish development we show that graded Hh and Fgf signaling independently help establis...
