The superiority trial of Baduanjin training on patients chronic low back pain: a study protocol for a randomized controlled trial.

Background: CNSLBP accounts for 85% of all LBP cases and impairs physical health, quality of life, and work productivity, posing a significant health and economic burden. Baduanjin (BDJ) exercises are traditional Chinese Qi Gong mind-body exercises that have been practiced for over 1,000 years. However, the standard BDJ protocol established by the State Sports General Administration does not stimulate core muscles, limiting the effectiveness of low back pain rehabilitation.

Fe@CN exhibited a synergy between adsorption-degradation processes due to the co-existence of FeC and FeN active sites.

LiCoO cathode surface modification with optimally structured LiPO for outstanding high-voltage cycling performance.

While researchers often adopt a higher operating voltage to further enlarge the actual specific capacity of LCO to expand its application scope and market share, this triggers some more intractable issues in that the capacity decays obviously and causes the attendant problem of safety. LiPO shows the advantage of increasing the energy density of lithium-ion batteries due to its characteristic ionic conduction when coated onto an LCO cathode. Enhancing the conductivity of cathode materials is the key factor in the success of raising their operating voltage to meet emerging market demands.

[Development of a Portable Chronic Non-specific Low Back Pain Measurement System].

We developed a portable non-specific low back pain measurement system EasiLBP and evaluated its performance in collecting EMG signals:during the wearer's movement without the assistance of a doctor, the collection of EMG signals by portable devices met problems such as large noise interference, difficulty in accurately calibrating the start and end points of the action interval, and imbalanced samples for feature recognition, et al.

Portable device and a medical EMG acquisition equipment Thought Technology FlexComp Infiniti 10 were used to perform EMG measurements on 15 patients with non-specific low back pain and 15 normal people.

Sequence-Controlled Polymers with Furan-Protected Maleimide as a Latent Monomer.

Herein, a novel methodology for preparing sequence-controlled polymers is illustrated by using a latent monomer, furan protected maleimide (FMI). At 110 °C, FMI is deprotected by retro Diels-Alder (rDA) reaction, and the released MI is immediately involved in the cross-polymerization with styrene (St) to deliver heterosegments. At 40 °C the rDA reaction does not proceed, therefore homo-poly(styrene) segments are produced.

Water-soluble and biocompatible MnO@PVP nanoparticles for MR imaging in vitro and in vivo.

The uniform-sized manganese oxide nanoparticles (the oleic-capped MnO NPs) were synthesized by the thermal decomposition of Mn-oleate complex and were transferred into water with the help of cationic surfactant of cetyltrimethyl ammonium bromide (CTAB), then the poly(vinylpyrrolidone) (PVP) membrane was further coated on to them with the aid of anionic dispersant of poly(styrenesulfonate) (PSS) by layer-by-layer electrostatic assembly to render them water soluble and biocompatible.
