Ractopamine, as an alternative beta-agonist to clenbuterol, is more and more used as leanness-enhancing agent in the swine industry. This work presents a new molecularly imprinted polymer (MIP) using ractopamine as template for dispersive solid-phase extraction of trace ractopamine and the structural related beta-agonists in animal tissues. The binding(More)
Novel magnetic molecularly imprinted polymer (MIP) beads using ractopamine as template for use in extraction was developed by microwave heating initiated suspension polymerization. Microwave heating, as an alternative heating source, significantly accelerate the polymerization process. By incorporating magnetic iron oxide, superparamagnetic composite MIP(More)
Auxin is a crucial phytohormone for precise control of growth and development of plants. Due to its low concentration in plant tissues which are rich in interfering substances, the accurate determination of auxins remains a challenge. In this paper, a new strategy for isolation and enrichment of auxins from plant tissues was obtained by the magnetic(More)
A novel sample preparation method for auxin analysis in plant samples was developed by vacuum microwave-assisted extraction (VMAE) followed by molecularly imprinted clean-up procedure. The method was based on two steps. In the first one, conventional solvent extraction was replaced by VMAE for extraction of auxins from plant tissues. This step provided(More)
In this paper, an enhanced power-save multi-poll (PSMP) combining conventional PSMP with Downlink Multiuser Multiple Input Multiple Output (MU-MIMO) is proposed to further improve the energy efficiency of wireless local area network (WLAN) communication system, especially for multiuser WLAN system. The energy consumption in PSMP downlink transmission time(More)
Spatial Modulation (SM) is utilized to overcome the negative influences of inter-channel interference (ICI) and enhance the spectral efficiency in multiple-input and multiple-output (MIMO) systems. Bit-interleaved Coded Spatial Modulation (BICSM) is proposed with the aim of improving the Bit Error Rate (BER) performance of SM systems. In our paper, a novel(More)
BACKGROUND Traditional Chinese medicine (TCM) has a long history in the treatment of psoriasis vulgaris. We aimed to evaluate the clinical efficacy and safety of Chinese herbal Pulian ointment in treating psoriasis vulgaris of blood-heat syndrome. METHODS A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Participants with(More)
