A simple and environment-friendly electrochemical method using activated glassy carbon electrodes (aGCE) for monitoring the residues of tetracycline in pork samples was developed. A two-step pretreatment procedure was established for activating the glassy carbon electrode surface, including mechanical polishing and electrochemical pretreatment. In the supporting electrolyte solution of 0.2 M sodium sulfate (at pH 2.5), the electrochemical response of TC was characterized by two irreversible oxidation peaks at +0.95 V and +1.05 V vs. saturated calomel electrode.

Exosomes are promising tools for improving cancer care, but conversely may also contribute to tumor progression. Here, we highlight recently discovered roles of exosomes in modulating immune responses in cancer, with emphasis on exosomal surface proteins and on RNA and DNA content. We also discuss how exosomes could be exploited as biomarkers and delivery vehicles in cancer therapy.

This paper aims to design the multi-cell cross-sectional thin-walled columns with two crashworthiness criteria. An explicit finite element analysis (FEA) is used to derive higher-order response surfaces for these two objectives. In the process of multiobjective crashworthiness optimization, Deb and Gupta method was utilized to find out the knee points from the Pareto solutions space.

Tetrodotoxin analogues (TTXs) have been broadly applied in many fields. Viscera of pufferfish from Viet Nam was reported to contain a high level of TTXs, indicating a promising source for isolation of TTXs. In this work, critical factors affecting TTX recovery yield from pufferfish viscera collected from fishermen in the Can Gio coast of Viet Nam were optimized using response surface methodology (RSM).

Ebook "Measuring biological impacts of nanomaterials" reviews several aspects of the biological response to nanoscale particles on a molecular and cellular level. Nanoscale materials and nanoscale particles in particular have interesting properties and beneficial applications. While they thus have entered our daily lifes on many different levels (from electronics, over textiles, packaging or surface modifications, to biomedical applications), general rules describing their interaction with biological structures and biological matter are still difficult to derive.
