Comparative Evaluation of the Apical Sealability of AH Plus and RealSeal SE Using 5.25% Sodium Hypochlorite with 17% EDTA and 10% Citric Acid as Irrigants-An Study.

Background: Apical microleakage is considered to be a common reason for the clinical failure of endodontic therapy. Three dimensional sealing of the root canal is one of the main goals of endodontic treatment and is essential for preventing reinfection of the canal and for preserving the health of the periapical tissues, Recently Epoxy resin sealers have been used because of their reduced solubility apical seal and micro-retention to root dentine.

Aim And Objective: This in vitro study was done to evaluate and compare the apical sealability of AH Plus and RealSeal SE using 5.

Effect of Metformin on systemic chemokine responses during anti-tuberculosis chemotherapy.

Background: Metformin (MET), by boosting immunity, has been suggested as a host-adjunctive therapy to anti-tuberculosis treatment (ATT).

Evaluation of HLA-G 14bp Ins/Del and +3142 C/G Polymorphisms in Type 1 Diabetes among South Indian Population.

Background: Type 1 diabetes (T1D) is a multifactorial autoimmune disease, involving strong genetic components with familial predisposition. Human leukocyte antigen-G (HLA-G) is a non-classical HLA-class I molecule having several immunomodulatory functions. Polymorphisms in are associated with several autoimmune diseases including T1D.

Association of Vitamin D Deficiency and Vitamin D Receptor Gene Polymorphisms with Type 1 Diabetes Risk: A South Indian Familial Study.

Objective: Vitamin D is a potent immune modulator and is associated with autoimmune diseases, including type 1 diabetes (T1D). The vitamin D levels and its receptor gene polymorphisms together in T1D are not yet investigated in the South Indian population. The present study focused on exploring the significance of vitamin D levels and vitamin D receptor (VDR) gene polymorphisms with the risk of developing T1D in the South Indian population.

A Case of Posttransplant Fibrillary Glomerulonephritis.

Fibrillary glomerulonephritis (FGN) is a rare form of glomerulonephritis, usually occurring in concurrence with other conditions such as hepatitis C, dysproteinemia, autoimmune conditions, diabetes mellitus, and malignancy. The diagnosis is made by the presence of randomly oriented fibrillar deposits with a mean diameter of 20 nm, which stain positive for IgG and C3 and are negative for congo red and thioflavin T stains. Staining for DNAJB9 (DnaJ homolog subfamily B member 9) is a recently discovered mode of diagnosis of FGN without electron microscopy.

The microbiome and rheumatic heart disease: current knowledge and future perspectives.

Rheumatic heart disease (RHD) is a cardiovascular disease caused by an autoimmune response to group A Streptococcus (GAS) infection resulting in the damage of heart valves. RHD is the most commonly acquired heart disease among children and young adults with a global burden of over 40 million cases accounting for 306,000 deaths annually. Inflammation in the heart valves caused due to molecular mimicry between the GAS antigens and host cardiac proteins is facilitated by cytokines, cross-reactive antibodies and CD4 T cells.

A Prospective Multi-Institutional Observational Study on ER, PR, HER2/NEU, and Ki-67 Expression and Discordance Pattern in Primary and Metastatic and Recurrent Carcinoma Breast and Its Therapeutic Implications and Prognostic Outcome.

Only few studies reported in literature that has elucidated in detail the implications of molecular typing in metastatic and recurrent breast cancer. In this prospective study, we have analysed in depth the pattern of expression, discordances of molecular markers in various metastatic sites, and recurrent cases and their response to chemotherapy/targeted agents and the prognostic outcome. The primary aim of the study was to determine ER, PR, HER2/NEU, and Ki-67 from recurrent and metastatic carcinoma breast to study the expression pattern and discordance and also to study the degree of discordance in relation to the site of metastasis and pattern of metastasis (synchronous vs metachronous) and discordance pattern with the response to chemotherapy and median overall survival rates in months in available subset of patients.
