In this study a 3-factor, 3-level Box-Behnken design was used to prepare optimized docetaxel (DTX) loaded pegylated poly lactide-co-glycolide (PEG-PLGA) NPs with polymer concentration (X1), drug concentration (X2) and ratio of the organic to aqueous solvent (X3) as the independent variables and particle size (Y1), poly dispersity index (PDI) (Y2) and drug loading (Y3) as the responses. The cyto...
Introduction Modified gene activities (transcription alterations) are known to precede phenotypic changes that are associated with normal (developmental) and pathophysiological (disease) processes in all biological systems especially in the brain. Procedures to evaluate gene activity in the brain are not routinely performed because the techniques used rely on biopsy or autopsy samples. As the r...

PURPOSE Nano dense-silica (dSiO2) has many advantages such as adjustable core-shell structure, multiple drug delivery, and controllable release behavior. Improving the gastric tumor-specific targeting efficiency based on the development of various strategies is crucial for anti-cancer drug delivery systems. METHODS Superparamagnetic iron oxide nanoparticles (SPION) were coated with dSiO2 as c...
Brown and beige adipocytes are potent therapeutic agents to increase energy expenditure and reduce risks of obesity and its affiliated metabolic symptoms. One strategy to increase beige adipocyte content is through inhibition of the evolutionarily conserved Notch signaling pathway. However, systemic delivery of Notch inhibitors is associated with off-target effects and multiple dosages of appli...
Current cancer chemotherapy is frequently associated with short- and long-term side effects, affecting the quality of life of cancer survivors. Because malignant cells are known to overexpress specific surface antigens, including receptors, targeted drug delivery is often utilized to reduce or overcome side effects. The current study involves a novel targeting approach using specifically design...

Superparamagnetic nanoparticles (SPION) were prepared by alkaline co-precipitation of ferric and ferrous chlorides in aqueous solution. The obtained particles were mixed at various ratios with different polymer solutions to obtain either SPION coated with polyvinyl alcohol (Mowiol 383), (PVA-SPION) or SPION coated with PVA modified by functional groups (amino-SPION, carboxy-SPION, and thiol-SPI...
PLGA microspheres are widely studied for controlled release drug delivery applications, and many models have been proposed to describe PLGA degradation and erosion and drug release from the bulk polymer. Autocatalysis is known to have a complex role in the dynamics of PLGA erosion and drug transport and can lead to size-dependent heterogeneities in otherwise uniformly bulk-eroding polymer micro...
context biocompatible polymers are potentially effective for dental infections as delivery carriers of disinfectants or antibiotics into the root canal system (rcs). this study aimed to review polymeric microspheres enabling a controlled release of endodontic medicaments. evidence acquisition a literature search was carried out in the pubmed database (may 2013) using the following keywords: “po...
