Tai Chi versus conventional exercise for improving cognitive function in older adults: a pilot randomized controlled trial.

Studies have shown that Tai Chi and conventional exercise can modify the brain through distinct mechanisms, resulting in different brain adaptations. Therefore, it is conceivable to speculate that these two exercise modalities may have different effects on improving cognitive function. This study was a parallel group, assessor-blinded, pilot randomized controlled trial comparing the effects of Tai Chi and conventional exercise on improving cognitive function in older persons with mild cognitive impairment (MCI).

Microplastics (MPs) pollution is increasingly appreciated as a significant environmental issue, however, the large-scale pattern of MPs in farmland soils and its associated environmental impacts are unknown. This study investigated a national-scale distribution of micro(meso)plastics (MMPs) in the soil of 30 farmlands across China. The abundance of MMPs in soils was 25.

The impact of gliadin and glutenin on the formation and structure of starch-lipid complexes.

This study evaluated the influence of the main gluten fractions (gliadin and glutenin) on the physicochemical properties of binary wheat starch-Lauric acid (WS-LA) complexes during heat processing to explore the complex structure and digestion of WS-LA in the presence of gluten. Ternary WS-LA-glutenin complexes were prepared at different pH (5.2 and 7), whereas WS-LA-gliadin was prepared using ethanol, and their physicochemical properties were analyzed.

Effects of Tai Chi or Exercise on Sleep in Older Adults With Insomnia: A Randomized Clinical Trial.

Importance: Previous studies that have shown tai chi to improve sleep were mainly based on subjective assessments, which might have produced results confounded by self-reporting bias.

Objective: To compare the effectiveness of tai chi for improving sleep in older adults with insomnia with conventional exercise and a passive control group using actigraphy-based objective measurements.

Design, Setting, And Participants: This randomized, 3-arm, parallel group, assessor-masked clinical trial was conducted at a single research unit in Hong Kong between August 2014 and August 2018.

[Regulation mechanism of plant hormones on secondary metabolites].

Plant hormones participate in the regulation of plant growth, and have significant physiological activities. Secondary metabolites are important raw materials of pharmaceutical and chemical industry, which have attracted extensive attention due to their economic and medicinal value. With the development of biotechnology, plant hormones have played an important role in regulating the synthesis of secondary metabolites.

Regional variations in geographic access to inpatient hospices and Place of death: A Population-based study in England, UK.

Background: There is much variation in hospice use with respect to geographic factors such as area-based deprivation, location of patient's residence and proximity to services location. However, little is known about how the association between geographic access to inpatient hospice and hospice deaths varies by patients' region of settlement.

Study Aim: To examine regional differences in the association between geographic access to inpatient hospice and hospice deaths.

Solvothermal Synthesis of Novel Magnetic Nickel Based Iron Oxide Nanocomposites for Selective Capture of Global- and Mono-Phosphopeptides.

A facile solvothermal method was developed for synthesis of magnetic nickel-based iron oxide nanocomposites (MNFOs) with different ratios of Ni to Fe for different reaction time. Two factors including dosage of Ni source and length of reaction were investigated for influence on the morphology and composition of MNFOs, as well as their distinct selectivity for different phosphopeptides. After thorough characterization, the possible formation mechanism of MNFOs was proposed.

Effect of artesunate and relation with TGF-β1 and SMAD3 signaling on experimental hypertrophic scar model in rabbit ear.

Artesunate (ART) is the derivative of artemisinin isolated from the traditional Chinese medicine qinghao. Although several studies reported the efficiency of artesunate in the treatment of malaria, inhibiting fibroblasts and collagen synthesis, the association between artesunate and scar formation is unclear. The research was designed to study the significance of artesunate (ART) on the expression of transforming growth factor (TGF-β1) and small mother against decapentaplegic (SMAD3) in rabbit's ear hypertrophic scar model.

Joint Machine Learning and Game Theory for Rate Control in High Efficiency Video Coding.

In this paper, a joint machine learning and game theory modeling (MLGT) framework is proposed for inter frame coding tree unit (CTU) level bit allocation and rate control (RC) optimization in high efficiency video coding (HEVC). First, a support vector machine-based multi-classification scheme is proposed to improve the prediction accuracy of CTU-level rate-distortion (R-D) model. The legacy "chicken-and-egg" dilemma in video coding is proposed to be overcome by the learning-based R-D model.

Medical Image Fusion Based on Feature Extraction and Sparse Representation.

As a novel multiscale geometric analysis tool, sparse representation has shown many advantages over the conventional image representation methods. However, the standard sparse representation does not take intrinsic structure and its time complexity into consideration. In this paper, a new fusion mechanism for multimodal medical images based on sparse representation and decision map is proposed to deal with these problems simultaneously.
