Nanoparticle Drug Delivery The encapsulation of nanoparticles in hydroxypropyl methyl cellulose is key to treat colorectal cancer through oral administration. In article 2202672 by Ilaria Rea, Hélder A. Santos, and co-workers, gelatin-coated diatomite loaded with galunisertib are functionalized an anti-L1-CAM antibody that targets metastatic colon cells. These then encapsulated a gastro-resista...

Although percutaneous titanium implants have become one of the best choices as retainers in the facial defects, peri-implantitis still occurs at a significant rate. This unwanted complication occurs due to adhesion of bacteria and subsequent biofilm formation. To solve this problem, we have developed a novel antibiotic nanodelivery system based on self-decomposable silica nanoparticles. In this...

There has been a great interest in application of nanoparticles as biomaterials for delivery of therapeutic molecules such as drugs and genes, and for tissue engineering. In particular, biopolymers are suitable materials as nanoparticles for clinical application due to their versatile traits, including biocompatibility, biodegradability and low immunogenicity. Biopolymers are polymers that are ...

Biodegradable poly(lactide-co-glycolide) (PLGA) nanoparticles, containing human parathyroid hormone (PTH (1-34)), prepared by a modified double emulsion-solvent diffusion-evaporation method, were incorporated in porous freeze-dried chitosan-gelatin (CH-G) scaffolds. The PTH-loaded nanoparticles (NPTH) were characterised in terms of morphology, size, protein loading, release kinetics and in vitr...

Background: Progress in the field of biology and biochemistry has led to the discovery of numerous bioactive peptides and proteins in the last few decades. Delivery of therapeutic proteins/peptides has received a considerable amount of attention in recent years. Methods: In this study, a two-step desolvation method was used to produce biodegradable hydrophilic gelatin nanoparticles (GNP) as a d...

Glycosaminoglycans, the most abundant heteropolysaccharides, have an inevitable role in tissue hydration, cell adhesion, regulation of cell growth and proliferation. Glycosaminoglycanchitosan-gelatin (GCG) scaffold incorporated with Hemigraphis colorata silver nanoparticles was prepared. The study confirmed the physical cross linking of the scaffold using scanning electron microscopy (SEM) and ...

This paper proposes a novel type of multifunctional envelope-type mesoporous silica nanoparticle (MSN) to achieve cancer cell targeting and drug-controlled release. In this system, MSNs were first modified by active targeting moiety hyaluronic acid (HA) for breast cancer cell targeting and hyaluronidases (Hyal)-induced intracellular drug release. Then gelatin, a proteinaceous biopolymer, was gr...

More than 32,000 patients are diagnosed with pancreatic cancer in the United States per year and the disease is associated with very high mortality (1). Urgent need exists to develop novel clinically-translatable therapeutic strategies that can improve on the dismal survival statistics of pancreatic cancer patients. Although gene therapy in cancer has shown a tremendous promise, the major chall...

the aim of this study was to investigate the influence of various treatments with filter-aids on pomegranate juice quality. the pomegranate used in this study was malas variety. different treatments in cold clarification method attempted were pectolitic enzyme, pectolitic enzyme-gelatin-bentonit, pectolitic enzyme-gelatin-silica sol, pectolitic enzyme-gelatin-bentonit-silica sol, gelatin-benton...

Nanofiber scaffolds and bio-ceramic nanoparticles have been widely used in bone tissue engineering. The use of human induced pluripotent stem cells (hiPSCs) on this scaffold can be considered as a new approach in the differentiation of bone tissue. In the present study, a polyaniline-gelatin-polycaprolactone (PANi-GEL-PCL) composite nanoscaffold was made by electrospinning and modified superfic...
