We investigated whether Aluminum (Al) doping tunes band gap energy level as well as selective cytotoxicity of ZnO nanoparticles in human breast cancer cells (MCF-7). Pure and Al-doped ZnO nanoparticles were prepared by a simple sol-gel method....
Nanotechnology based therapeutics can offer an alternative platform in a wide variety of biomedical applications. Here we report novel cytotoxicity preventive potential of molybdenum nanoparticles (Mo NPs) in human breast (MCF-7) and fibrosarcoma (...
Recent evidences indicate potential Escherichia coli involvement in colorectal cancer etiology. Colorectal cancer cells are exclusively colonized by enteroinvasive E. coli, which regulates several factors that can affect colorectal cancer...
titative determination of gatifloxacin in tablets, solid lipid nanoparticles (SLNs) and eye-drops using a very simple and rapid chromatographic technique was validated and developed. Formulations were analyzed using a reverse phase SUPELCO® 516 C-18...
The purpose of this research was to investigate the use of biodegradable poly(D,L-lactic-co-glycolic acid) nanoparticles (PLGA-NP) as a vaccine delivery system to codeliver antigen, ovalbumin (OVA) along with monophosphoryl lipid A (MPLA) as...
Poly(ethylene oxide)-block-poly(epsilon-caprolactone) (PEO-b-PCL) and newly developed poly(ethylene oxide)-block-poly(alpha-benzyl carboxylate epsilon-caprolactone) (PEO-b-PBCL) micelles were evaluated for the solubilization and delivery of...
The purpose of this study was to evaluate the efficacy of poly(lactic-co-glycolic acid) (PLGA)-based vaccines in breaking immunotolerance to cancer-associated self-antigens. Vaccination of mice bearing melanoma B16 tumors with PLGA nanoparticles (NP...
This study was conducted to formulate a nonviral delivery system for the delivery of small interfering RNA (siRNA) to B16 melanoma cells in vitro. For this purpose, oleic and stearic acid modified derivatives of branched polyethylenimine (PEI) were...
Persistent activation of signal transducer and activator of transcription 3 (STAT3) has been shown to impart several oncogenic features in many solid and blood tumors. In this study, we investigated the potential of nanoparticles based on...
PURPOSE:
Tumors can escape immune eradication by harnessing dendritic cell (DC) maturation. However, DC types used as in vitro models to study tumor-mediated immunosuppression possess fundamental variability that could influence research outcomes....
In dendritic cells (DCs), the induction of signal transducer and activator of transcription 3 (STAT3) by tumor-derived factors (TDFs) renders DCs tolerogenic and suppresses their antitumor activity. Therefore, silencing STAT3 in DCs is beneficial...
We have previously developed micelles of methoxy poly(ethylene oxide)-b-poly(ε-caprolactone) as vehicles for the solubilization and delivery of cyclosporine A (CsA). These micelles were able to reduce the renal uptake and nephrotoxicity of CsA. The...
Persistent activation of STAT3 plays a major role in cancer progression and immune escape. Therefore, targeting STAT3 in tumors is essential to enhance/reactivate antitumor immune response. In our previous studies, we demonstrated the efficacy of...
One scenario by which tumors escape immune recognition is the constitutive activation of signal transducer and activator of transcription 3 (STAT3). This transcription factor mediates the production of tumor-derived factors that negatively influence...
Thymocytes are subjected to processes of selection during their life in the thymus; negative selection for autoreactive thymocytes and positive selection for self-MHC restricted self-tolerant cells. Interestingly, signals for positive or negative...
Although local colonic delivery is achievable through several strategies, colon cancer is still considered one of the leading causes of death worldwide. Failure of chemotherapeutics to exhibit efficient anticancer activity might be attributed to the...
This study describes corneal permeation of gatifloxacin from solid lipid nanoparticle (SLN) through the cornea and its effect on corneal hydration level. The aqueous humor levels of gatifloxacin after single topical instillation in Gate(®) Eyedrops...
This study aims to improve gatifloxacin bioavailability to the eye using solid-lipid nanoparticles (SLN). Cationic SLNs were prepared by o/w-microemulsion method using stearylamine. The generated formulations were optimized by three-factor, three-...
The microbiome is a collection of all microbial species that coexist with an individual. These organisms influence several aspects of individual body functions. Probiotic organisms are generally beneficial components of microflora and confer normal...
Cucurbitacin I is a hydrophobic molecule that exerts a degree of polarity, which is expected to complicate its loading in PLGA nanoparticles by the classical emulsion solvent evaporation technique. In the current study, variants of emulsion solvent...
