Injectable polymeric hydrogels for the delivery of therapeutic agents: A review

Since drug delivery systems have become one of the most promising areas of human health related research, the applications of biomaterials such as hydrogels have been widely investigated. Possessing unique hydrophilic, biocompatible network structures and the ability to form solid-like gel states once administered, injectable hydrogels facilitate the encapsulation and release of therapeutic agents, including drugs, proteins, genes and cells, in a controllable manner. A wide and diverse range of techniques have been used to generate hydrogels, from chemical cross-linking, such as photo-polymerization, click chemistry, enzyme-catalyzed reactions, Schiff’s base reactions, and thiol-based Michael reactions, to physical cross-linking induced by temperature, pH, ionic interaction, guest– host inclusion, stereo-complexation or complementary binding. This review covers the utilization of various injectable hydrogel systems for the delivery of therapeutic agents from the viewpoint of cross-linking methods.

Anticancer effects of saponin and saponin–phospholipid complex of Panax notoginseng grown in Vietnam

Title:  Anticancer effects of saponin and saponin–phospholipid complex of Panax notoginseng grown in Vietnam Authors:  Dang Kim, T. Nguyen Thanh, H. Nguyen Thuy, D., (...) Boonsiri, P. Bui Thanh, T. Keywords:  Antitumor;Breast cancer;Panax notoginseng;Saponin;Saponin–phospholipid complex Issue Date:  2016 Publisher:  Hainan Medical University Citation:  Scopus Abstract:  Objective To evaluate the antitumor activity both in vitro and in vivo of saponin–phospholipid complex of Panax notoginseng. Methods The in vitro cytotoxic effect of saponins extract and saponin–phospholipid complex against human lung cancer NCI-H460 and breast cancer cell lines BT474 was examined using MTS assay. For in vivo evaluation of antitumor potential, saponin and saponin–phospholipid complex were administered orally in rats induced mammary carcinogenesis by 7,12-dimethylbenz(a)anthracene, for 30 days. Results Our data showed that saponin–phospholipid complex ha...

The Contribution of Owners’ Human and Social Capital to Firm Performance in Vietnamese Small and Medium Enterprises

Small and medium enterprises (SMEs) have held an increasingly important position in Vietnam’s economy, contributing significantly to the economic growth of the country. Despite that vital role, research on this subject is very limited, scarce in quantity, and questionable in quality, particularly on owners’ human and social capital as a significant input forSME performance. Therefore, this article aims at testing the relationship between owners’ human and social capital resources and firms’ financial performance, using the survey of 2,739 SMEs in Vietnam in 2004 conducted by Vietnam’s Institute of Labor Studies and Social Affairs (ILSSA) and The Faculty of Economics- Copenhagen University. The study then shows some significant results and opens future research directions.
