Leveraging selective knockdown of gene by polyethyleneimine-siRNA-chitosan reduced gold nanoparticles to promote osteogenesis in MC3T3-E1 & MEF cells.

Osteoporosis is a systemic skeletal disorder characterized by reduced osteoblast differentiation, predominantly by overexpression of the gene. A layer-by-layer approach enabled encapsulation of siRNA to enhance the short half-life and poor transfection capacity of siRNA. Polyethyleneimine and siRNA on chitosan-coated gold nanoparticles (PEI/siRNA/Cs-AuNPs) were engineered using chitosan-reduced gold nanoparticles.

Hyaluronate-functionalized hydroxyapatite nanoparticles laden with methotrexate and teriflunomide for the treatment of rheumatoid arthritis.

Rheumatoid arthritis (RA), an autoimmune inflammatory disorder is currently incurable. Methotrexate and Teriflunomide are routinely prescribed drugs but their uses are limited due to severe hepatotoxicity. Hyaluronic acid (HYA) is a targeting ligand for CD44 receptors overexpressed on inflamed macrophages.

Facile functionalization of Teriflunomide-loaded nanoliposomes with Chondroitin sulphate for the treatment of Rheumatoid arthritis.

This research aims to coat Teriflunomide (TEF) loaded conventional nanoliposomes (CON-TEF-LIPO) with Chondroitin sulphate (CS) to produce CS-TEF-LIPO for the effective treatment of Rheumatoid arthritis (RA). Both CON-TEF-LIPO and CS-TEF-LIPO were produced, characterized and evaluated for their active targeting potential towards CD44 receptors. Cell cytotoxicity, cell viability and intracellular uptake study on differentiated U937 and MG-63 cells demonstrated the active targeting of CS-TEF-LIPO towards CD44 receptors.

Prevalence and associations of moderately increased albuminuria in patients with type 2 diabetes in United Arab Emirates.

Background And Aims: Our study sought to investigate the prevalence of moderately increased albuminuria in United Arab Emirates (UAE) nationals with type 2 diabetes, and to identify the associated factors.

Methods: This prospective cross-sectional study was conducted in two hundred and seven UAE nationals with type 2 diabetes mellitus attending the internal medicine department of a secondary care hospital. Moderately increased albuminuria was estimated in random spot urine samples and was defined as urinary albumin-to-creatinine ratio (UACR) of 3-30 mg/mmoL.

Biocompatible Nanovesicular Drug Delivery Systems with Targeting Potential for Autoimmune Diseases.

Autoimmune diseases are collectively addressed as chronic conditions initiated by the loss of one's immunological tolerance, where the body treats its own cells as foreigners or self-antigens. These hay-wired antibodies or immunologically capable cells lead to a variety of disorders like rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, multiple sclerosis and recently included neurodegenerative diseases like Alzheimer's, Parkinsonism and testicular cancer triggered T-cells induced autoimmune response in testes and brain. Conventional treatments for autoimmune diseases possess several downsides due to unfavourable pharmacokinetic behaviour of drug, reflected by low bioavailability, rapid clearance, offsite toxicity, restricted targeting ability and poor therapeutic outcomes.

Design and development of bioinspired calcium phosphate nanoparticles of MTX: pharmacodynamic and pharmacokinetic evaluation.

The aim of this investigation is the management of rheumatoid arthritis (RA) by developing methotrexate-loaded calcium phosphate nanoparticles (MTX-CAP-NP) and to evaluate pharmacokinetic and pharmacodynamic behavior in adjuvant induced arthritis model. The nanoparticles were synthesized by wet precipitation method and optimized by Box-Behnken experimental design. MTX-CAP-NPs were characterized by TEM, FTIR, DSC and XRD studies.

Development and validation of stability indicating reversed-phase liquid chromatographic method for simultaneous quantification of methotrexate and teriflunomide in nanoparticles and marketed formulation.

Methotrexate (MTX) and teriflunomide (TEF) are the two most effective disease-modifying antirheumatic drugs used as combination therapy for rheumatoid arthritis and no robust high-performance liquid chromatography (HPLC) method is available for their simultaneous estimation to date. Therefore, we have developed and validated an isocratic reversed-phase HPLC method for simultaneous analysis of MTX and TEF spiked in the form of active pharmaceutical ingredients, tablets and nanoformulations. The best separation was achieved on a BDS, C , 4.

Emerging Role of CD44 Receptor as a Potential Target in Disease Diagnosis: A Patent Review.

Background: The CD44 receptor is a cell surface glycoprotein, which mediates many physiological and pathological activities. Its key role is to provide defence against inflammatory reactions by cellular transmigration and cell signalling. In pathological conditions, it gives destructive outcomes by mediating migration of pathogenic cells to vital organs resulting in tissue and organ damage.

Transungual Delivery of Ketoconazole Nanoemulgel for the Effective Management of Onychomycosis.

Ketoconazole (KCZ) nanoemulgel containing permeation enhancer was formulated as a vehicle for transungual drug delivery, and its efficacy to inhibit the growth of onychomycotic dermatophytes was investigated in vitro. Different components of oil-in-water nanoemulsions were moderately agitated by classical titration method and passed through a high-pressure homogenizer to formulate various nanoemulsions, which were further identified by constructing pseudo-ternary phase diagrams. Stress-stability testing was carried out for the nanoemulsions, and those that passed these tests were characterized for mean droplet size, zeta potential, morphology, pH, refractive index, viscosity and transmittance.
