Comparison of Microalbuminuria Status in Type 2 Diabetes Mellitus Patients With Chronic Periodontitis: A Cross-Sectional Study.

Background Diabetes has increased the risk for various other ailments in various organs of the body. This can be contributing to periodontitis also as it is the sixth complication related to diabetes mellitus. There is a bidirectional relationship between both. Given the high global prevalence of type-2 diabetes mellitus (T2DM) with periodontitis, it is of great importance to determine the link between periodontitis and microalbuminuria in T2DM patients, which shows early renal disease. Methodology In the present study, a total of 500 patients having T2DM were assessed for periodontitis using Community Periodontal Index (CPI). Anthropometric and biochemical measurements were obtained. Blood samples were estimated for glycemic control tests such as fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), and lipid profile. The subjects who participated in the study were categorized into three groups depending on the albuminuria level. The data were tabulated and analyzed using SPSS Statistics software (IBM Corp., Armonk, USA). Results Out of 500 T2DM subjects, 342 subjects had periodontitis. A statistically significant difference was found in FPG, HbA1c, total cholesterol (TC), triglycerides, and low-density lipoprotein (LDL) between subjects with periodontitis and without periodontitis using a t-test (p = <0.001). The prevalence of normoalbuminuria, micro-, and macroalbuminuria among periodontitis patients was 24.6%, 72.8%, and 2.6% respectively, and the Chi-square analysis revealed that was highly significant. In terms of albuminuria, one-way analysis of variance (ANOVA) revealed statistically significant differences among the periodontitis subjects for the following variables: inputs such as the number of teeth, diabetes mellitus (DM) duration, the level of LDL, and also the depth of the pocket. Intergroup comparison of variables among subjects with albuminuria using the statistical test of Tukey Post Hoc found that there is a significant difference between normoalbuminuria and microalbuminuria. CPI score, tooth mobility, smoking, education level, family income, tooth brushing duration, along with the use of other dental hygiene aids was also found to be statistically significant among subjects with periodontitis. Conclusion The study concluded that T2DM patients had a higher incidence of microalbuminuria among individuals with periodontitis. These subjects also had significantly higher HbA1c and FPG levels than subjects with normoalbuminuria. In addition, subjects with periodontitis exhibited a significant reduction in the total teeth numbers present in the case of albuminuria. The longitudinal correlation between DM, microalbuminuria, and periodontitis could be further investigated in detail to explore possible pathways.

Targeting Ovarian Solid Tumors by Elastin-Like Polypeptide Drug Conjugates: Current Trends and Future Prospectives.

BACKGROUND: Ovarian cancer is one of the leading causes of death worldwide. Polymers have low cytotoxicity and high functionalizability and are hence used for drug delivery systems, tissue engineering, and polymer therapeutics. In drug delivery systems, polymer-drug conjugates have shown considerable promise, especially in anticancer chemotherapy. OBJECTIVE: Anticancer Drug Delivery Systems (DDS) deliver drugs to the tumor site leading to reduced exposure of the drugs to healthy cells and hence reduced side effects. Efforts have been made in the past to develop effective DDS using stimuli-responsive polymers like thermosensitive and pH-sensitive polymers. CONCLUSION: Elastin-like Polypeptides (ELP), one of the thermoresponsive polymers, have been identified as drug carriers in anticancer therapy. ELP-drug conjugates have the potential and can be used effectively in combination with hyperthermia for targeting drugs to solid tumors. This review reports on the use of ELPs in cancer therapy, its biomedical applications, and recent developments to target drugs to ovarian solid tumors.

Potential Role of In Vitro-In Vivo Correlations (IVIVC) for the Development of Plant-Derived Anticancer Drugs.

BACKGROUND: Conventional medicines, along with herbal formulations of Chinese, serve as the primary source and hub of active new drugs where the initial research concentrates on the extraction and isolation of bioactive lead compound(s) to treat several diseases largely for cancer. Plant-derived natural products and their analogs reveal a significant source of several clinically useful anticancer agents. Herbs and herbal derived active compounds play an unavoidable role in the treatment, drug discovery and delivery for decades, as evidenced by numerous existing marked drugs and various cancer-related molecular targets in clinical development. OBJECTIVE: Solubility, resistance and metabolic limitations of the drug can be overcome by suitable molecular modifications. Due to enhancements in tumor targeting technology, some agents who failed in earlier clinical studies are also stimulating renewed interest. In this connection, In Vitro-In Vivo Correlation (IVIVC) plays an important role in the development of dosage forms in the field of pharmaceutical technology. CONCLUSION: IVIVC tool fastens and improves the drug development process and product quality, which is also utilized in internal control for scale-up to improve formulations and alternative production processes. Most importantly, this IVIVC tool lessens the number of human studies during new pharmaceuticals developments. In this review, we would like to grab the attention of readers to the importance and significance of IVIVC for natural products of anticancer drugs examples such as Docetaxel, Etoposide phosphate, 6-Gingerol, Capsaicin, etc.

The red cell distribution width as a sensitive biomarker for assessing the pulmonary function in automobile welders- a cross sectional study.

CONTEXT: Welding fumes are considered as a risk factor for pulmonary diseases and a periodic spirometry is essential to evaluate the lung function of the welders. The Red Cell Distribution Width (RDW) is a red cell measurement which is provided by automated haematology analyzers. It reflects the range of the red cell sizes which are measured within a sample. Few studies have shown a relationship between the RDW values and the changes in the spirometry. AIMS: This study was aimed at correlating the RDW% and the spirometry FEV1/FVC ratio (%) among automobile welders (cases). Further, we have analyzed the effect of smoking on the FEV1/FVC ratio% and the RDW% in the cases. SETTINGS AND DESIGN: A cross sectional study was done on 50 welders and 50 non-welding office workers (controls) who were working in an automobile industry on the outskirts of Chennai, india. All the cases were arc welders and the controls were from the same production unit, who had never worked as welders. This study was conducted during the period from March 2012 to May 2012. METHODS AND MATERIAL: The demographic data, smoking habits, work history and the respiratory symptoms were gathered by using a standard self -administered questionnaire. A complete haemogram study was done and pulmonary function tests were performed for both the cases and the controls. All the cases and the controls were examined in the hospital outpatients room and subsequently, their blood samples were collected. The pulmonary function tests were conducted in the spirometry room in the hospital. The statistical analysis was done using the SPSS, version 15.0. RESULTS: A statistically significant inverse correlation was found between the RDW% and the FEV1/FVC ratio% in the cases. CONCLUSIONS: RDW can be used as a biomarker to identify the pulmonary compromise in automobile welders.

Spectroscopic characterization studies of 1-methyl indole with benzene derivatives.

The NMR and fluorescence quenching of benzene, chlorobenzene and methoxybenzene in acetonitril and 2-propanol solvents have been carried out with a view to understand the quenching mechanisms. The quenching is found to be appreciable and shows positive derivation in the stern-volmer plots. UV absorbance is used to measure the excitation wavelength. Lifetime measurements are carried out and the quenching rate constant kq is also calculated. Molar extinction co-efficient, stoke's shift are also calculated. The NMR study is used to conform if there is any complex formation between 1-methylindole with the benzene derivatives.
