Activated synovial macrophages play a key role in Rheumatoid Arthritis (RA). Recent studies have shown that folate receptor beta (FRβ) is specifically expressed by activated macrophages. Therefore a folate-based nanodevice would provide the possibility of delivering therapeutic agents to activated macrophages without affecting normal cells and tissues. This study shows for the first time the so...
Background and objective: Resulting in the accumulation of somatic mutations in cancer cells caused. Breast cancer is the most commonly diagnosed cancer among women worldwide. The use of nanoscale drug delivery systems is important for effective treatment. The main aim of this study was to determine effects of chitosan conjugated to docetaxel nanoparticles in treatment of breast cancer. Methods...
The aim of the present study was to develop a transdermal system for controlled delivery of melatonin combining three strategies: nanoencapsulation of melatonin, drying of melatonin-loaded nanocapsules, and incorporation of nanocapsules in a hydrophilic gel. Nanocapsules were prepared by interfacial deposition of the polymer and were spray-dried using water-soluble excipients. In vitro drug rel...
Aim To study the in vitro and in vivo anticandidal activity of nanocapsulated bovine lactoferrin. Materials & methods In vitro and in vivo antimicrobial activities were conducted to study the anticandidal activities of nanocapsules (NCs). Results The NCs showed good anticandidal activities. The disruption of cell wall and cell membrane was noted via microscopy studies. The NCs changed the n...
The use of nanoparticles may be particularly advantageous in treating bacterial infections due to their multiple simultaneous mechanisms of action. Nanoencapsulation is particularly useful for lipophilic drugs. In this scenario, triclosan is considered a good candidate due to its lipophilicity, broad-spectrum activity, and safety. In the present study, we have developed and characterized an ant...
Poly(ε-caprolactone) (PCL) nanocapsules have been previously developed as a carrier system for atrazine. However, the efficacy of this nanoformulation against weeds commonly found in crop cultures has not been tested yet. Here, we evaluated the post-emergence herbicidal activity of PCL nanocapsules containing atrazine against Amaranthus viridis (slender amaranth) and Bidens pilosa (hairy beggar...
The interaction between cells and biopolymers is the evaluation indicator of the biocompatibility of materials. The purpose of this work was to examine the responses of retinal pigment epithelial (RPE) cells to genipin (GP) or glutaraldehyde (GTA) cross-linked chitosan by means of cell viability assays, cytokine expression analyses, and apoptosis assays. Evaluations of non-cross-linked chitosan...
Background: Biological molecules such as therapeutic proteins and peptides have provided ample opportunities for further improvements in health wellbeing. However, biomacromolecules face stability challenges regarding premature processing digestion, whenever any enteric delivery route is considered. Hence, oral guar films entrapping peptide-containing chitosan microparticles been developed a ne...
cancer is one of the main cause of mortality in the world which appears by the effect of enviromental physico-chemical mutagen and carcinogen agents. the identification of new cytotoxic drug with low sid effects on immune system has developed as important area in new studies of immunopharmacology. curcumin is a natural polyphenol with anti-oxidative, anti-inflammatory and anti-cancer properties...
