Background: Up to 25% of diabetic patients will develop a diabetic foot ulcer. Chronic wounds such as diabetic foot ulcers often fail to heal with conventional therapies. In recent years, it has been identified that chronic wounds are usually associated with elevated level of matrix metalloproteinases (MMPs). Doxycycline, a cheap tetracycline antibiotic, has been shown to inhibit MMPs both in vitro and in vivo indepe Read More

Background: The clinical application of cells and the development of new delivery systems have allowed significant advances in the field of cell therapy and encapsulation in recent years. The ability to combine cells and biocompatible matrices in the encapsulation of cells providing long-term delivery has provides new therapeutic alternatives in the development of new therapies. Methods: A structured search of bibliographic d Read More

Background: The indications for Allergen immunotherapy (AIT) in patients suffering from House Dust Mite (HDM)-related allergic diseases are presently based on incomplete data. This is essentially based on the fact that HDM allergy is difficult to evaluate in clinical trials, due to the largely variable allergen exposure and symptoms, and to the long periods of observation needed to assess the effects. In addition, at variance Read More

Background: Aurones are a sub-set of the flavone family that possess a number of biological activities, including anti-cancer, anti-inflammatory, anti-microbial, anti-parasitic and anti-viral. Due to their high availability, simple synthesis, and generally low toxicity, aurones could be attractive candidates for safer cancer drugs. This study aims to evaluate the anti-proliferation and anti-metastasis activity of a series of synthesize Read More

Background: PS916, chitosan derivative with shown activities in atherosclerotic and fatty liver, is being investigated as an anti-atherosclerotic agent in clinical trials in China. Methods: Fluorescein-labeled PS916 (PS916-FTC) was prepared by the reaction with fluorescein isothiocyanate. The pharmacokinetics and bio-disposition of PS916-FTC were studied in rats after oral or intravenous administration. Results: Analysis of the Read More

Background: Enterotoxigenic Escherichia coli (ETEC) is the main cause of fatal diarrhea in piglets during the first week of life and over the time of weaning. Pathogenesis of ETEC-causing diarrhea involves intestinal colonization mediated by fimbriae. Although, both IgY and egg yolk phosvitin (PV) possess antimicrobial activity, their combined activity has not been explored. A combination of IgY specific for ETEC and metal-chel Read More

Background: Microemulsions are attractive delivery systems for therapeutic proteins and peptides due to their ability to enhance bioavailability. Although different proteins and peptides have been successfully delivered through such ternary systems, no information can be found about protein loading and the formulation stability when such microemulsions are prepared with pharmaceuticallyapproved oils and surfactant Read More

Background: Angiogenesis is critical for the growth of tumor by supplying nutrients and oxygen that exacerbates the metastasis and progression of cancer. Noninvasive imaging of angiogenesis during the tumor therapeutic processes may provide novel opportunities for image-guided tumor management. Objective: Here, we want to develop a mouse animal model for assessing cancer progression and angiogenesis in the sa Read More

Background: The renewable feedstock derived biodegradable plastics are important in various industries such as packaging, agricultural, paper coating, garbage bags and biomedical implants. The increasing water and waste pollution due to the available decomposition methods of plastic degradation have led to the emergence of biodegradable plastics and biological degradation with microbial (bacteria and fungi) extracel Read More
