SMART: On-Site Rapid Detection of Nucleic Acid from Plants, Animals, and Microorganisms in under 25 Minutes.

The rapid on-site nucleic acid detection method is urgently required in many fields. In this study, we report a portable and highly integrated device for DNA detection that combines ultrafast DNA adsorption and rapid DNA amplification. The device, known as silicon film mediated recombinase polymerase amplification (RPA) for nucleic acid detection (SMART), can detect target DNA in less than 25 min from plants, animals, and microbes.

Effect of the Dispersion States of Azone in Hydroalcoholic Gels on Its Transdermal Permeation Enhancement Efficacy.

The objective of this study was to investigate the effect of dispersion states of azone in gels on the transdermal permeation of levamisole hydrochloride (LH). LH hydroalcoholic gels containing azone of different dispersion states were prepared by varying the contents of azone and Tween 80, and the in vitro transdermal permeation of LH across excised rat skin was evaluated. Depending on the content of azone, mixed solvents, and solubilizer used, azone presented as dissolved molecules, solubilized in micelles, and fine or coarse emulsion droplets in gels.

KCC2 expression changes in Diazepam-treated neonatal rats with hypoxia-ischaemia brain damage.

Hypoxia-ischaemia brain damage (HIBD) is a major type of perinatal brain injury in newborns. In this study, we investigate the short- and long-term neuroprotective effects of Diazepam on neonatal rats with HIBD and the potential mechanisms underlying its protective effects. Seven-day-old Sprague-Dawley rats were subjected to left carotid artery ligation followed by a 2-h exposure to 8% oxygen and 92% nitrogen.

Establishment and characterization of a paclitaxel‑resistant human esophageal carcinoma cell line.

The aim of this study was to establish a new paclitaxel (PTX)-resistant human esophageal squamous carcinoma (ESCC) cell line and investigate its biological characteristics. The resistant cell line (EC109/Taxol) was developed in vitro by intermittent exposure of the human ESCC cell line EC109 to a high concentration of PTX with time-stepwise increment over a period of 6 months. The MTT assay was performed to test the drug resistance of EC109 and EC109/Taxol cells.
