The Effects of Salvia officinalis Gel as an Adjunct to Scaling and Root Planning in Patients with Periodontitis (Clinical and Immunological Study)

Background: Phytotherapy is the usage of herbal species with medicinal properties for the management of various diseases. Gingivitis and periodontitis are diseases that involve the role of both the bacteria and the host immune response. Over the years, various researches have shown the importance of herbal products in the management of periodontal diseases. Aims of the study: To evaluate the efficacy of locally applied Salvia officinalis gel as adjunctive in the treatment of chronic periodontitis. Subjects and methods: Fourteen patients (10 males and 4 females) with chronic periodontitis were enrolled in the present study with total number of twenty-eight periodontal pockets utilizing a split mouth design, the pockets were divided into two groups, the test group which was treated with scaling and root planning procedure and the application of the S. officinalis gel, and the control group that treated with scaling and root planning only. Plaque index (PI) and gingival index (GI) were recorded for each site. Gingival crevicular fluid (GCF) was collected from each site by using PerioCol paper strips. The concentration of the transforming growth factor beta-1 in the gingival crevicular fluid was quantified by a high sensitivity enzyme-linked immunosorbent assay. Results: The test group demonstrated a significant reduction in GI at 1-week and 1-month after the treatment comparing to baseline (1.14 vs. 1.64, p = 0.003, and 1.21 vs. 1.64, p = 0.028, respectively), while no significant reduction in the PI at recall visits comparing to baseline. The control group demonstrated no significant reduction in PI and GI at recall visits, comparing to baseline. Both the test and control groups demonstrated no significant reduction in the transforming growth factor-beta 1 concentration in the gingival crevicular fluid at one week after the treatment comparing to baseline, while at one month after the treatment only the test group demonstrated a significant reduction comparing to baseline (3.91 vs. 9.62, p = 0.044). Conclusion: The findings of the present study indicated that the S. officinalis gel has a potential anti-inflammatory role in the treatment of chronic periodontitis by monitoring both the clinical and immunological parameters.

A Digital-Based Optimal AVR Design of Synchronous Generator Exciter Using LQR Technique

In this paper a new structure for the AVR of the power system exciter is proposed and designed using digital-based LQR. With two weighting matrices R and Q,  this method produces an optimal regulator that is used to generate the feedback control law. These matrices are called state and control weighting matrices and are used to balance between the relative importance of the input and the states in the cost function that is being optimized. A sample power system composed of single machine connected to an infinite- bus bar (SMIB) with both a conventional and a proposed Digital AVR (DAVR) is simulated. Evaluation results show that the DAVR damps well the oscillations of the terminal voltage and presents a faster respo

Design of a PID-Lead Compensator for a Twin Rotor Aerodynamic System (TRAS)

This paper deals with a Twin Rotor Aerodynamic System (TRAS). It is a Multi-Input Multi-Output (MIMO) system with high crosscoupling between its two channels. It proposes a hybrid design procedure that combines frequency response and root locus approaches. The proposed controller is designated as PID-Lead Compensator (PIDLC); the PID controller was designed in previous work using frequency response design specifications, while the lead compensator is proposed in this paper and is designed using the root locus method. A general explicit formula for angle computations in any of the four quadrants is also given. The lead compensator is designed by shifting the dominant closed-loop poles slightly to the left in the

Tuning of PID Controllers for Quadcopter System using Cultural Exchange Imperialist Competitive Algorithm

Quadrotors are coming up as an attractive platform for unmanned aerial vehicle (UAV) research, due to the simplicity of their structure and maintenance, their ability to hover, and their vertical take-off and landing (VTOL) capability. With the vast advancements in small-size sensors, actuators, and processors, researchers are now focusing on developing mini UAV’s to be used in both research and commercial applications. This work presents a detailed mathematical nonlinear dynamic model of the quadrotor which is formulated using the Newton-Euler method. Although the quadrotor is a 6 DOF under-actuated system, the derived rotational subsystem is fully actuated, while the translational subsystem is under-actuated. The der
