to answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. in the present paper, controlled metal based drug (pd(ii) complex) release manner of β‑lactoglobulin (β-lg) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...

Most infectious diseases are caused by pathogenic infiltrations from the mucosal tract. Nowadays, the use of vaccines has been widely investigated for the prevention of different infectious diseases, infertility, immune disorders, malignancies, and allergies. Broad-spectrum adjuvant substances have been studied for immune system stimulation with a greater efficiency against specific antigens. V...

nanoparticles have been at the center of research focus as a new promising material for the treatment of cancer in recent years. although many chemotherapy drugs for cancer treatment are available, their potential toxicity is the main point of concern. on the other hand, the conventional chemotherapeutic approach has not been found to be very efficient in colorectal cancer (crc) as the drug mol...

background: several multiphase flow analyses have been developed to predict the fate of particles used in inhalation drug delivery; however, the collapse of droplets during their passage through respiratory tract has not been investigated. objective: to assess the probability of droplet collapse in the upper respiratory tract. methods: a 3d model of mouth-to-second generation airway after the t...

conclusions it was shown that combination of pectin and eudragits can relatively control drug release in the upper gi. on the other hand, pectin degraded in the presence of pectinase and formulations were susceptible to the colonic media. results it was shown that in the presence of pectin, formulations without erl had a relative resistance to drug release in sgf. pellets containing pectin and ...

the field of vaccinology provides excellent promises to control different infectious and non-infectious diseases. genetic immunization as a new tool in this area by using naked dna has been shown to induce humoral as well as cellular immune responses with high efficiency. this demonstrates the enormous potential of this strategy for vaccination purposes. dna vaccines have been widely used to de...

The in vivo application of cytolytic peptides for cancer therapeutics is hampered by toxicity, nonspecificity, and degradation. We previously developed a specific strategy to synthesize a nanoscale delivery vehicle for cytolytic peptides by incorporating the nonspecific amphipathic cytolytic peptide melittin into the outer lipid monolayer of a perfluorocarbon nanoparticle. Here, we have demonst...
