Multichannel highly secure wireless communication system with information camouflage capability.

Information metasurface has shown great potential in wireless communications owing to its ability to flexibly control electromagnetic waves. However, it is still a big challenge to achieve high-security and large-channel capacity wireless communications by a simple system. Here, we propose a space-polarization-division multiplexing secure wireless communication system with information camouflage capability based on the information metasurface, which can realize multichannel encrypted wireless communications with different polarization coding strategies independently and simultaneously.

Computer-Vision Based Gesture-Metasurface Interaction System for Beam Manipulation and Wireless Communication.

Hand gesture plays an important role in many circumstances, which is one of the most common interactive methods in daily life, especially for disabled people. Human-machine interaction is another popular research topic to realize direct and efficient control, making machines intelligent and maneuverable. Here, a special human-machine interaction system is proposed and namedas computer-vision (CV) based gesture-metasurface interaction (GMI) system, which can be used for both direct beam manipulations and real-time wireless communications.

Biological activity of EXf, a peptide analogue of exendin-4.

Exendin-4 is an incretin mimetic that has been developed for the treatment of patients with type 2 diabetes. EXf is an available carboxy-terminal truncated fragment of exendin-4 with two amino acid substitutions. The purpose of these studies was to evaluate the biological activity of EXf.

The PPARalpha/gamma dual agonist chiglitazar improves insulin resistance and dyslipidemia in MSG obese rats.

1. The aim of this study was to investigate the capacity of chiglitazar to improve insulin resistance and dyslipidemia in monosodium L-glutamate (MSG) obese rats and to determine whether its lipid-lowering effect is mediated through its activation of PPARalpha. 2.

Pioglitazone can ameliorate insulin resistance in low-dose streptozotocin and high sucrose-fat diet induced obese rats.

Aim: To investigate the effect of the peroxisome proliferator-activator receptor (PPAR)-gamma agonist, pioglitazone, on insulin resistance in low-dose streptozotocin and high sucrose-fat diet induced obese rats.

Methods: Normal female Wistar rats were injected intraperitoneally with low-dose streptozotocin (STZ, 30 mg/kg) and fed with a high sucrose-fat diet for 8 weeks. Pioglitazone (20 mg/kg) was administered orally to the obese and insulin-resistant rats for 28 d.

[Ameliorations of pioglitazone on insulin resistance in spontaneous IGT-OLETF rats].

Aim: To investigate the ameliorations of pioglitazone, a member of the thiazolidinedione group of antidiabetic agents, on insulin resistance in spontaneous OLETF rats with impaired glucose tolerance (IGT-OLETF).

Methods: One group of IGT-OLETF rats was orally administered pioglitazone at the dose of 20 mg x kg(-1) (qd) for 2 weeks. Another group was given the same volume of solvent as control.

[Effects of conjugated linoleic acid on obese MSG mice with insulin resistance].

Aim: To study the effect of conjugated linoleic acid (CLA) on obese MSG mice with insulin resistance.

Methods: About four months old, obese MSG mice with insulin resistance were divided into control, CLA and rosiglitazone groups and drugs were administrated ig once a day. Body weights were recorded regularly, insulin and glucose tolerance were tested.
