Background The assessment of malignant potential oral submucous fibrosis grades vis-à-vis their progression towards malignancy is associated with expression possible multiple molecular markers. Aims To analyse p63, E-cadherin and CD105 in this premalignant pathosis a view to unravel understand the these molecules as Methods mucosal biopsies (normal, without dysplasia) were studied routine H&E, by immunohistochemistry for expression. p63 was assessed percentage positive nuclei. estimated...

Antibacterial activity of nanoparticles (NPs) and nanocomposites (NCs) has received wide spread attention in biomedical applications. In this direction, the authors prepared zinc oxide (ZnO), iron (Fe3O4), their composite including reduced graphene (rGO) by hydrothermal method. The structural microstructural properties synthesised NPs NCs were investigated XRD, FT-IR, UV-Vis, TGA, TEM analysis. PEG-coated ZnO Fe3O4 form hexagonal wurtzite inverse spinel structures, respectively. forms...

Multiple emulsions are thermodynamically stable systems that mark applications in various fields including drug delivery systems. They allow enhanced availability of drugs, greater absorption, and present reduced toxicity, among other desirable properties. In this work, we aimed to formulate a unique double emulsion (O1/W + W1/O2/W/W) with three bioactive components viz. Ocimum tenuiflorum oil, Cocos nucifera oil crystalline Cinnamomum camphora. Three surfactants different HLB values...

Background: Oral submucous fibrosis (OSF) is a pre-cancerous condition with features of chronic, inflammatory and progressive sub-epithelial fibrotic disorder the buccal mucosa. In this study, malignant potentiality OSF has been assessed by quantification immunohistochemical expression epithelial prime regulator-p63 molecule in correlation to its (oral squamous cell carcinoma [OSCC] normal counterpart [normal oral mucosa [NOM]). Attributes spatial extent distribution p63+ epithelium have...

Abstract Prostaglandin analogues (PG), beta‐blockers (BB) or their combination (PG+BB) are used primarily to reduce the intraocular pressure (IOP) pathologically associated with glaucoma. Since, fibrosis of trabecular meshwork (TM) is a major aetiological factor in glaucoma, we studied effect these drugs on fibrosis‐associated gene expression TM primary glaucoma patients. In present study, and iris open‐angle (n = 32) angle‐closure 37) patients were obtained surgically during trabeculectomy...

Direct noninvasive visualization of wound bed with depth information is important to understand the tissue repair. We correlate skin swept-source-optical coherence tomography (OCT) histopathological and immunohistochemical evaluation on traumatic lower limb wounds under honey dressing compare assess repair features acquired noninvasively invasively. Analysis optical biopsy identifies an uppermost brighter band for stratum corneum region specific thickness (p < 0.0001) gray-level intensity...

Oral squamous cell carcinoma (OSCC) is a highly invasive and pervasive human oral neoplasia, accounting for approximately 90% of all cavity carcinomas worldwide. Despite technological advancements, tumor spread consequent relapse result in meagre 5- year survival rates less than 60%. Metastasis the culmination multiphase transition, characterized as epithelial-to-mesenchymal transition (EMT), which stipulates gradual acquisition migratory phenotype epithelial cells. Physiologically, EMT...

Honey is recognized traditionally for its medicinal properties and also appreciated as a topical healing agent infected noninfected wounds. This study evaluates impact of honey-based occlusive dressing on nonhealing (nonresponding to conventional antibiotics) traumatic lower limb wounds (n = 34) through clinicopathological immunohistochemical (e.g., expression p63, E-cadherin, Collagen I III) evaluations enrich the scientific validation. Clinical findings noted nonadherence honey with...
