Proteomics Approach to Identify Serum Biomarkers Associated with Gastric Cancer in South Indian Tamils.

Background: Identifying cancer-specific biomarkers is a crucial step in the disease screening process at a very early stage of tumor development. In recent years, Quantitative proteomic approaches have gained importance in identifying novel candidate markers in cancer. Gastric cancer has always been known as a life-threatening medical condition with high mortality rates.

Hyaluronan-based nano-formulation with mesoporous silica enhances the anticancer efficacy of phloroglucinol against gastrointestinal cancers.

Gastrointestinal cancers are one among the most frequently reported cancers where colorectal and gastric cancers ranks third leading cause of cancer related death worldwide. Phloroglucinol, a well-known therapeutic agent for cancer, where its usage has been limited due to its poor water solubility and bioavailability. Hence, our study aims to synthesize and characterize Hyaluronan grafted phloroglucinol loaded Mesoporous silica nanoparticles (MSN-PG-HA).

Potential Use of 3D CORAGRAF-Loaded PDGF-BB in PLGA Microsphere Seeded Mesenchymal Stromal Cells in Enhancing the Repair of Calvaria Critical-Size Bone Defect in Rat Model.

Our previous study evidenced that the 3D CORAGRAF loaded with PLGA microsphere constitutes PDGF-BB can support cell attachment and proliferation and can induce an osteogenic commitment of mesenchymal stromal cells in the in vitro condition. However, how this construct can perform in pathophysiological conditions in terms of repairing critical bone defects is yet to be understood. A study was therefore conducted to investigate the regeneration potential of calvaria critical-size defects using CORAGRAF + PLGA with PDGF-BB + mesenchymal stromal cells (MSCs) in a rat model.

Emerging Promise of Phytochemicals in Ameliorating Neurological Disorders.

Background: The field of medicine and synthetic drug development have advanced rapidly over the past few decades. However, research on alternative medicine such as phytochemicals cannot be ignored. The main reason for prominent curiosity about phytochemicals stems from the belief that usage of natural compounds is safer and has lesser detrimental side effects.

Comparative Proteomic Analysis Reveals Novel Biomarkers for Gastric Cancer in South Indian Tamil Population.

Background: Gastric Cancer (GC) remains a major global health problem due to a poor understanding of its progression at the molecular level and a lack of early detection or diagnosis. Early detection is highly crucial for improving prognosis. The incidence of GC is very high in countries, like India, due to the limitations among the established biomarkers for GC owing to poor sensitivity and specificity.

TLR5 Polymorphisms rs2072493, rs5744174, and rs5744168 Are Not Genetic Risk Factors for Chronic Helicobacter pylori Infection in Indian Tamils.

The incidence of Helicobacter pylori (H. pylori) infection and gastric cancer is on the rise in India, and the genetic factors influencing the increased susceptibility in Indian population remain obscure. Toll-like receptors (TLRs) play a major role in innate immune system and genetic polymorphisms affecting their function were reported to enhance the risk for H.

Genetic variants of TLR4 and TLR9 are risk factors for chronic Helicobacter pylori infection in South Indian Tamils.

Toll like receptors (TLRs) are a class of molecular pattern recognition receptors, elicits a strong inflammatory immune response against pathogens. Helicobacter pylori (H. pylori), a gram negative flagellate colonizes the human stomach, is responsible for the development of chronic gastritis and gastric carcinoma.

Effect of Pithecellobium dulce (Roxb.) Benth. fruit extract on cysteamine induced duodenal ulcer in rats.

The edible fruits of Pithecellobium dulce (Roxb.) Benth. are traditionally used for various gastric complications in India.

Antiulcerogenic activity of hydroalcoholic fruit extract of Pithecellobium dulce in different experimental ulcer models in rats.

Ethnopharmacological Relevance: The ethnopharmacological importance of Pithecellobium dulce is evidenced by its traditional use for gastric complications. The aim of the study is to evaluate the gastroprotective activity and the mechanism of action of hydroalcoholic fruit extract of P. dulce (HAEPD) in rats by using chemical and stress induced ulcer models.

Acute and sub-acute toxicity study of hydroalcoholic fruit extract of Pithecellobium dulce.

This study was carried out to evaluate the acute and sub-acute toxicity profile of the hydroalcoholic fruit extract (HAEPD) of Pithecellobium dulce (Leguminosae). Albino rats were treated orally with 100, 200 and 500 mg kg(-1) bodyweight (BW) of HAEPD for 90 days to assess its sub-acute toxicity. HAEPD at single doses of 100, 500, 1000, 2000 and 4000 mg kg(-1) BW was also administered to rats to assess its acute toxicity.
