Reversible Thermochromic Organosilicon Fibers Based on TiO@AgI Composites: Preparation, Properties, and Potential Applications.

The application of reversible thermochromic fibers (RTFs) is expanding from the smart wearable field toward industrial temperature detection and safety warning; however, most RTFs suffer from low color change temperature thresholds and poor thermal stability, which restrict their applications in medium and high-temperature places (>100 °C). Currently, overheating of equipment is a key factor that causes safety accidents, and the development of reliable visualized temperature warning materials is of great practical significance for accident prevention. To address these issues, TiO@AgI is blended with a ternary organosilicon oil spinning solution via a high-temperature air-induced crosslinking method to obtain a reversible thermochromic organosilicon fiber (TSiF) suitable for use in medium and high-temperature environments owing to its thermal stability.

Improved Salt Tolerance in L. Overexpressing a Synthetic Stress-Resistant Module DICW.

Salt stress adversely impacts plant physiology by causing ionic, osmotic, and oxidative stress, ultimately hindering growth and yield. The genus contains unique stress resistance genes, and previous studies have shown that proteins such as IrrE, Csp, and WHy enhance stress tolerance in plants and microbial cells. However, their role in L.

Twenty years of ocean observations with China Argo.

The international Argo program, a global observational array of nearly 4 000 autonomous profiling floats initiated in the late 1990s, which measures the water temperature and salinity of the upper 2 000 m of the global ocean, has revolutionized oceanography. It has been recognized one of the most successful ocean observation systems in the world. Today, the proposed decade action "OneArgo" for building an integrated global, full-depth, and multidisciplinary ocean observing array for beyond 2020 has been endorsed.

Protocol to access unknown flanking DNA sequences using Wristwatch-PCR for genome-walking.

Here we describe a protocol for wristwatch PCR, an approach based on wristwatch-like structure formed between walking primers to obtain unknown flanks. We specify the criteria for designing wristwatch primers and gene-specific primers. We detail how to set wristwatch primer permutations to obtain personalized walking outcomes and improve walking efficiency.

DAR-PCR: a new tool for efficient retrieval of unknown flanking genomic DNA.

Various PCR-based genome-walking methods have been developed to acquire unknown flanking DNA sequences. However, the specificity and efficacy levels, and the operational processes, of the available methods are unsatisfactory. This work proposes a novel walking approach, termed differential annealing-mediated racket PCR (DAR-PCR).

Wristwatch PCR: A Versatile and Efficient Genome Walking Strategy.

Genome walking is a method used to retrieve unknown flanking DNA. Here, we reported wristwatch (WW) PCR, an efficient genome walking technique mediated by WW primers (WWPs). WWPs feature 5'- and 3'-overlap and a heterologous interval.

Deoxyribonucleic Acid 5-Hydroxymethylation in Cell-Free Deoxyribonucleic Acid, a Novel Cancer Biomarker in the Era of Precision Medicine.

Aberrant methylation has been regarded as a hallmark of cancer. 5-hydroxymethylcytosine (5hmC) is recently identified as the ten-eleven translocase (ten-eleven translocase)-mediated oxidized form of 5-methylcytosine, which plays a substantial role in DNA demethylation. Cell-free DNA has been introduced as a promising tool in the liquid biopsy of cancer.

Spatial variations and long-term trends of potential evaporation in Canada.

Assessing the status and trend of potential evaporation (PE) is essential for investigating the climate change impact on the terrestrial water cycle. Despite recent advances, evaluating climate change impacts on PE using pan evaporation (E) data in cold regions is hindered by the unavailability of E measurements in cold seasons due to the freezing of water and sparse spatial distribution of sites. This study generated long-term PE datasets in Canada for 1979-2016 by integrating the dynamic evolutions of water-ice-snow processes into estimation in the Ecological Assimilation of Land and Climate Observations (EALCO) model.

Contributions of climate change to the terrestrial carbon stock of the arid region of China: A multi-dataset analysis.

Dryland ecosystems have been threatened in recent decades by rapid climate change. However, the effects of climate change and rising CO levels on the terrestrial carbon stock of the arid region of China remain unclear. In this study, we used three climate reanalysis datasets to drive an arid ecosystem model (AEM), which we used to assess uncertainties in spatial climate datasets.

Depression and anxiety mediate perceived social support to predict health-related quality of life in pregnant women living with HIV.

Pregnant women living with HIV represent one of the most high-priority groups for HIV treatment and health assessment. Although social support has been shown to be a protective factor for improved health-related quality of life (HRQoL), and depression and anxiety have been identified as two major causes of psychological distress among people living with HIV, it is still unclear how social support, anxiety, and depression interact to influence HRQoL. The objective of our study was to demonstrate the nature of predictors, direct effects and mediator effects among social support, anxiety, depression symptoms and HRQoL in pregnant women living with HIV.

Metabolic profiling of Gegenqinlian decoction in rat plasma, urine, bile and feces after oral administration by ultra high performance liquid chromatography coupled with Fourier transform ion cyclotron resonance mass spectrometry.

Gegenqinlian decoction (GQLD) as a traditional Chinese medical (TCM) prescription is made from four Chinese herbs and has been used for centuries to treat pyrexia and diarrhea. In this work, an ultra-high performance liquid chromatography coupled with Fourier transform ion cyclotron resonance mass spectrometry (UHPLC-FT-ICR-MS) method was established to profile the metabolic fate of GQLD in rat plasma, urine, bile and feces. The analysis was performed on a Waters Acquity UPLC HSS T3 column (2.

A plasma metabonomic analysis on potential biomarker in pyrexia induced by three methods using ultra high performance liquid chromatography coupled with Fourier transform ion cyclotron resonance mass spectrometry.

Pyrexia usually is a systemic pathological process that can lead to metabolic disorders. Metabonomics as a powerful tool not only can reveal the pathological mechanisms, but also can give insight into the progression of pyrexia from another angle. Thus, an ultra high performance liquid chromatography combined with Fourier transform ion cyclotron resonance mass spectrometry (UHPLC-FT-ICR-MS) metabonomic approach was employed for the first time to investigate the plasma biochemical characteristics of pyrexia induced by three methods and to reveal subtle metabolic changes under the condition of pyrexia so as to explore its mechanism.

Remote sensing of ecosystem health: opportunities, challenges, and future perspectives.

Maintaining a healthy ecosystem is essential for maximizing sustainable ecological services of the best quality to human beings. Ecological and conservation research has provided a strong scientific background on identifying ecological health indicators and correspondingly making effective conservation plans. At the same time, ecologists have asserted a strong need for spatially explicit and temporally effective ecosystem health assessments based on remote sensing data.

Comparison of laboratory and field remote sensing methods to measure forage quality.

Recent research in range ecology has emphasized the importance of forage quality as a key indicator of rangeland condition. However, we lack tools to evaluate forage quality at scales appropriate for management. Using canopy reflectance data to measure forage quality has been conducted at both laboratory and field levels separately, but little work has been conducted to evaluate these methods simultaneously.
