Abstract
BACKGROUND Although there is ample evidence in the literature supporting a significant positive association between key periodontal pathogens and established inflammatory markers of periodontitis and coronary artery disease (CAD), their exact role remain unclear. Especially, the role of viruses in the etiology and specific biomarkers have not been validated. Thus, the current study aims to evaluate the role of periodontal viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), and herpes simplex virus (HSV), as well as the inflammatory marker pentraxin-3 (PTX3), and to analyze their association with CAD. METHODS The study included 240 patients divided into four groups of 60 patients each: nonperiodontitis + noncardiac (NP+NC) group, periodontitis + noncardiac patients (P+NC) group, nonperiodontitis + cardiac patients (NP+C) group, and periodontitis + cardiac (P+C) group. The cardiac surgery group (C-S) was a subgroup of NP+C and P+C. It consisted of 60 patients from the abovementioned two cardiac groups in whom coronary artery bypass graft (CABG) was indicated. Demographic variables, cardiac parameters, and periodontal parameters were recorded. The viruses (EBV, CMV, and HSV) and the inflammatory marker PTX3 were evaluated in the subgingival plaque samples of all the four groups and atheromatous plaque samples of the C-S using reverse transcriptase-polymerase chain reaction (RT-PCR) and quantitative polymerase chain reaction (qPCR), respectively, and were compared between the groups. The results were obtained and statistically analyzed. RESULTS The demographic variables did not differ significantly between the groups, except for age. Systolic blood pressure, diastolic blood pressure, low-density lipoprotein, and random blood sugar were significantly higher in NP+C and P+C, whereas high-density lipoprotein was significantly lower (p ≤ 0.05) in the same. Plaque index (PI), probing pocket depth (PPD), and clinical attachment level (CAL) were significantly higher (p ≤ 0.05) in P+NC and P+C. PTX were significantly elevated in P+C among the four groups. On evaluating the subgingival plaque samples, EBV and CMV were significantly higher in the two periodontitis groups P+NC and P+C (p = 0.000). HSV was significantly higher in the two cardiac groups (NP+C and P+C) (p ≤ 0.05). Cardiac EBV and CMV were significantly elevated in the P+C group with a p value of 0.004 and 0.033, respectively. Cardiac HSV was found in the NP+C group with statistical insignificance (p = 0.410) between the groups. On correlation, oral PTX were significantly associated with bleeding index (BI), PPD, and CAL (p = 0.000). Similarly, cardiac PTX showed significant association with PI, BI, PPD, and CAL (p = 0.000). Oral and cardiac PTX also showed significant correlation with each other. Multiple logistic regression analysis revealed a significant association between CAL and oral EBV (p ≤ 0.05). Similarly, cardiac EBV showed a significant association with CAL and oral EBV (p ≤ 0.05). Multiple logistic regression analysis also revealed that both cardiac and oral PTX showed a significant association only with oral EBV, CMV, and HSV. CONCLUSION The results of the current study suggest that the clinical severity of periodontitis (CAL), etiology of periodontitis (EBV and CMV), and inflammatory marker of periodontitis (PTX3) were found to be significantly elevated in CAD. These findings suggests that periodontal diseases may be a risk factor that could influence the progression of CAD.

Abstract
Objectives Pentraxin 3 (PTX3) is a biomarker, associated with the pathogenesis of Periodontitis and coronary artery disease (CAD) individually, but their role in patients with both diseases remains unclear. The current study aims to evaluate the association of PTX in patients with concomitant periodontitis and CAD. Materials and Methods In a case-control study, 240 participants were selected and divided into four groups. Nonperiodontitis + noncardiac = 60 patients, periodontitis + noncardiac (P + NC) = 60 patients, nonperiodontitis + cardiac (NP + C) = 60 patients, periodontitis + cardiac (P + C) = 60 patients. Demographic variables, cardiac and periodontal parameters were recorded. PTX was evaluated in the subgingival plaque and atheromatous plaque samples using real-time quantitative polymerase chain reaction and compared between the groups. The results were statistically analyzed. Results Among the demographic variables, age showed a significant difference between the groups. Systolic and diastolic blood pressure, low-density lipoprotein, and random blood sugar were significantly higher in NP + C and P + C groups (P ≤ 0.05). The plaque index, probing pocket depth, and clinical attachment loss were significantly higher in P + NC and P + C groups (P ≤ 0.05). PTX was significantly elevated in P + C group (P = 0.000). Pearson's correlation revealed a significant correlation between the periodontal parameters and PTX in both the cardiac and oral samples. Conclusion PTX3 levels were elevated in CAD patients with periodontitis suggesting the influence of periodontal inflammation in the progression of CAD. PTX3 may serve as a diagnostic and prognostic tool for both periodontitis and CAD. This study could provide an understanding and awareness about the potential role of PTX3 in both periodontitis and CAD.

Abstract
OBJECTIVES The current study aims in evaluating the prevalence of Epstein-barr virus (EBV), Cytomegalovirus (CMV) and Herpes simplex virus (HSV) in periodontitis and/or Coronary artery disease (CAD) patients to compare with their healthy controls and insist their significance in the same. METHODOLOGY Two hundred and forty patients were divided into 4 groups. Non-periodontitis+non-cardiac (NP+NC) =60 patients, periodontitis+non-cardiac patients (P+NC)=60 patients, non-periodontitis+cardiac patients (NP+C)=60 patients and periodontitis+cardiac (P+C)=60 patients. Demographic variables, cardiac and periodontal parameters were recorded. EBV, CMV and HSV were evaluated in the sub- gingival plaque samples using RT-PCR (Real time polymerase chain reaction) and compared between the groups. The results were statistically analysed using Students t test, Pearson's chi square, Turkey post hoc analysis and multiple logistic regression analysis. RESULTS The demographic variables did not differ significantly between the groups, except for age. Systolic blood pressure, Diastolic blood pressure, Low density lipoprotein, Random blood sugar were significantly higher in NP+C and P+C (p≤0.05). The Plaque Index, Probing Pocket Depth and Clinical Attachment Loss (p≤0.05) were significantly higher in P+NC and P+C. EBV and CMV was significantly higher in the two periodontitis groups P+NC and P+C (p-value=0.000). HSV was significantly higher in the two cardiac groups (NP+C and P+C) (p≤0.05). Multiple logistic regression analysis revealed a significant association between EBV and CAL (p≤0.05). CONCLUSION The study concluded that higher prevalence of EBV and CMV were found in groups with periodontitis patients. This indicates the significant role of the viruses in periodontitis as confirmed by association of EBV and CAL. The viruses were said to be highest in periodontitis patients with CAD. This could pave a new link in the risk of CAD in periodontitis patients.

Abstract
Periodontitis is an inflammatory disease of the periodontium, which is a reflection of the overgrowth of oral commensals. This alteration in the oral microbiota initiates inflammation of the gingiva, which when left untreated, terminates with the resorption of the alveolar bone that may lead to a poor and hopeless prognosis. With upcoming trends in modulating the host's immunity, the role of regulatory T-cells has gained importance. These T-cells defend against inflammation and autoimmunity as they suppress both. However, in both the conditions, the regulatory cells are invariably reduced in number. Novel methods to enhance the function of Tregs have made their way in dentistry, as a promising approach to cure periodontitis. This article discusses various significant tests and trials of Tregs in the recent years.

Abstract
BACKGROUND Viruses are considered to be a newer family associated with inflammatory diseases. Yet the role of periodontal viruses in coronary artery diseases (CAD) remains unclear. Thus, the current study aims to evaluate the prevalence of periodontal viruses and compare the same in cardiac samples of CAD patients with and without periodontitis. METHODS A total of 60 patients with CAD indicated for coronary artery bypass graft surgery (CABG) were included. These were grouped into 36 patients with healthy periodontium (CAD only) and 24 patients with periodontitis (CAD + P). The demographic variables, cardiac parameters and periodontal parameters were recorded. Cardiac tissue samples were collected during the CABG surgery and were analyzed by reverse transcriptase polymerase chain reaction for periodontal viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV) and Herpes simplex virus. All the parameters were statistically analyzed. RESULTS Among the demographic variables, age was statistically significant between the groups. Plaque index, bleeding index, probing depth, and clinical attachment level (CAL) were significantly higher in CAD+P group (P ˂0.05). Periodontal viruses such as EBV and CMV were significantly higher (62.5% and 75% respectively, P ˂0.05) in the cardiac samples of the CAD+P than CAD only (25% and 47.2%, respectively). A significant association between EBV and CAL was revealed by multiple logistic regression analysis. (B = 0.374, P = 0.046) CONCLUSIONS: The results revealed a higher prevalence of periodontal viruses such as EBV and CMV in CAD patients with periodontitis suggesting it as one of the risk factors for CAD. This is supported by the fact that severity of periodontal disease (CAL) is associated with the presence of EBV in coronary artery plaque samples in the current study.

Abstract
INTRODUCTION Periodontal disease is the major cause of adult tooth loss and is commonly characterized by a chronic inflammation caused by infection due to oral bacteria. Members of Toll-Like Receptor (TLR) family recognize conserved microbial structures, such as bacterial lipopolysaccharides and activate signalling pathways that result in immune responses against microbial infections. AIM The aim of the present study was to assess the mRNA expression of Toll-Like Receptor 2 and 4 in tissues with or without chronic periodontitis. MATERIALS AND METHODS Gingival tissue samples were collected from controls (30 subjects with healthy periodontal tissues) and experimental group (30 subjects with chronic periodontitis). Total RNA was extracted and RT-PCR was done for evaluation of TLR-2 and TLR-4. Mann Whitney U-test, Pearson Chi-square Test was used for statistics. RESULTS The results showed that there is a significant (p-value= 0.004) association between TLR-4 and the experimental group comprising of chronic periodontitis patients in comparison to the insignificant (p-value= 0.085) TLR-2 expression. CONCLUSION This study concludes that TLR-2 and TLR-4 expressed in the gingival tissues recognize different bacterial cell wall components thus helping us to associate its potential in diagnosing periodontal disease. Hence, in the future, these scientific findings can pave the way in using TLR as a diagnostic biomarker for periodontal disease.

Abstract
In this paper, we analyze dark soliton propagation in nonlinear optical fibers with higher-order effects such as third order dispersion, self-steepening, and stimulated Raman scattering. We consider the Hirota equation and the higher-order nonlinear Schrödinger equation, and identify conditions for dark soliton propagation through Painlevé analysis. We also construct an explicit Lax pair, and Hirota bilinear form is used to generate one and two dark solitons.
