Effect of Non-Surgical Periodontal Treatment on Clinical and Biochemical Risk Markers of Cardiovascular Disease: A Randomized Trial

Abstract: Background: Various studies have shown periodontal disease is one of the risk factors for coronary heart disease (CHD), and periodontal treatment of patients with CHD has also been correlated with reduction in systemic markers of CHD. The aim of this study is to evaluate the effect of non-surgical periodontal treatment (NSPT) on the cardiovascular clinical and biochemical status of patients with CHD.Methods: Seventy known patients with CHD were allocated randomly to either a control group (C; no periodontal therapy) (n = 35) or an experimental group (E; NSPT in the form of scaling and root planing [SRP]) (n = 35). Cardiovascular status was assessed using clinical parameters such as pulse, respiratory rate, blood pressure (BP), and biochemical parameters, such as high-sensitivity C-reactive protein (hsCRP), lipid profile, and white blood cell (WBC) count, at baseline and 1, 3, and 6 months. Intergroup and intragroup comparisons were performed using Student t test, and P <0.05 was considered statistically s...

Bioinspired fluorescence carbon quantum dots extracted from natural honey: Efficient material for photonic and antibacterial applications

Abstract: Fluorescent carbon quantum dots were extracted from natural honey using the hydrothermal approach. The XRD and HRTEM investigations confirm the morphology of the carbon quantum dots (CQDs) are spherical shape with a diameter of 8.29 nm. The FTIR and XPS analysis indicate the effective incorporation of nitrogen and sulfuratoms into the CQDs. The sample demonstrated the blue fluorescence by the UV-light illumination ( λ ex = 365 nm ). When excited at 350 nm, the quantum yield of honey CQDs was found to be ∼ 4.192 % at the emission wavelength (431 nm). Crucially for the first time, the existing honey CQDs generates a strong nonlinear optical response relative to some semiconductor QDs. The non-linear optical characterization was investigated utilizing the Z-Scan method. These CQDs exhibit self-defocusing nonlinearity and strong nonlinear performance in the absorption. Also, the agar well diffusion method used to investigate the antimicrobial efficacy of the CQDs against the foodborne pathogens. It is inferred from the existing observations that honey CQDs have been used as effective optoelectronic devices and antimicrobial agents.

Micellar Nematic Phase in a Binary Mixture of Two Nonmesogenic Compounds

Abstract: We report the results of our studies on the optical and thermal properties of two nonmesogenic compounds, namely, tetradecyl trimethyl ammonium bromide (TTAB) and glacial acetic acid (GAA). The mixture exhibits very interesting schilieren texture of micellar nematic lyophase, smectic A (SmA), and SmG phases for all concentrations of TTAB sequentially when the specimen is cooled from its isotropic phase. The order parameter (S) of the micellar nematic phase is estimated with the help of temperature dependence of optical anisotropy from the measured refractive index and density data. The temperature variation of order parameter of the experimental curve is very well fitted with the Mayer–Saupe theoretical curve. The temperature variation of electrical conductivity is also discussed. The formation of above phases has been confirmed by optical X-ray and differential scanning calorimetry studies.
