The SsWRKY1 transcription factor of Saccharum spontaneum enhances drought tolerance in transgenic Arabidopsis thaliana and interacts with 21 potential proteins to regulate drought tolerance in S. spontaneum.

In this study, we characterized a WRKY family member gene, SsWRKY1, which is located in the nucleus and contains multiple stress-related cis-acting elements. In addition, constructed SsWRKY1-overexpressing Arabidopsis thaliana had higher antioxidant enzyme activity and proline content under drought stress conditions, with lower malondialdehyde content and reactive oxygen species (ROS) accumulation, and the expression levels of six stress-related genes were significantly upregulated. This indicates that the overexpression of SsWRKY1 in Arabidopsis thaliana improves resistance to drought stress.

Evaluation of genome size and phylogenetic relationships of the complex species.

Unlabelled: " complex" is a hypothetical group of species, which is supposed to be involved in the origin of modern sugarcane, and displays large genomes and complex chromosomal alterations. The utilization of restricted parents in breeding programs of modern cultivated sugarcane has resulted in a genetic blockage, which controlled its improvement because of the limited genetic diversity. The use of wild relatives is an effective way to broaden the genetic composition of cultivated sugarcane.

The Gene Coexpression Analysis Identifies Functional Modules Dynamically Changed After Traumatic Brain Injury.

Traumatic brain injury (TBI) is a major cause of morbidity and mortality, both in adult and pediatric populations. However, the dynamic changes of gene expression profiles following TBI have not been fully understood. In this study, we identified the differentially expressed genes (DEGs) following TBI.

Effectiveness and safety of 3 different traditional Chinese therapies for asthma in minors: A protocol for systematic review and network meta-analysis.

Introduction: Traditional Chinese medicine has been widely used in the treatment of asthma, but currently there has been no comprehensive evaluation on the efficacy and safety of different traditional Chinese medicine therapies, based on network meta-analysis (NMA).

Methods And Analysis: The retrieval strategy was strictly followed in the English databases PubMed, Embase, Cochrane Library, and Chinese databases: CNKI and Wanfang. The retrieval time was limited from the beginning of each database construction to September 12, 2020.

Design and implementation of a virtual capacitor based DC current suppression method for grid-connected inverters.

Integration of renewable energy (RE) sources, such as wind energy and photo voltaic (PV) energy, to a power network (grid) is usually achieved through an intermediate power electronic inverter. Ideally, the inverter is not expected to inject any form of DC component into the grid. However, this is not the case in practice as DC component are invariably generated and, subsequently, injected into the grid by the power converter, impacting on the overall power quality.

A dimensionally stable and fast-discharging graphite-silicon composite Li-ion battery anode enabled by electrostatically self-assembled multifunctional polymer-blend coating.

A high-performance graphite-Si composite anode for Li-ion batteries containing Si nanoparticles (NPs) attached onto graphite microparticles was synthesized by adopting a polymer-blend of poly(diallyl dimethyl-ammonium chloride) and poly(sodium 4-styrenesulfonate). The polymer-blend enabled uniform distribution of Si NPs during synthesis and served as a robust artificial solid-electrolyte interphase that substantially enhanced the cycle stability and rate performance of the composite electrode. The electrode exhibited a specific capacity of 450 mA h g(-1), 96% capacity retention at a 10 C-rate, 95% retention after 200 cycles, and the same electrode expansion behavior as a pristine graphite electrode.

A mechanically robust and highly ion-conductive polymer-blend coating for high-power and long-life lithium-ion battery anodes.

A mechanically robust and ion-conductive polymeric coating containing two polymers, polyethylene glycol tert-octylphenyl ether and poly(allyl amine), with four tailored functional groups is developed for graphite and graphite-Si composite anodes. The coating, acting as an artificial solid electrolyte interphase, leads to remarkable enhancement in capacity reversibility and cycling stability, as well as a high-rate performance of the studied anodes.

[Biodegradation mechanisms of 17beta-estradiol (E2) by lake sediment].

Batch experiments using lake sediment mud liquors spiked with E2 were performed under aerobic and anaerobic conditions. The catabolic mechanisms of E2 were also induced. The results indicate that under aerobic condition, 99% of E2 can be removed from aqueous phase after as short as 24 h.

[Effects of organic pollutants in drinking water on the removal of dimethyl phthalate by advanced oxidation processes].

Humic acids were used to simulate natural organic compounds in water for the investigation of DMP oxidation by three different AOPs (advanced oxidation processes) of UV-H2O2, O3 and UV-O3. The results showed that pseudo-first-order reaction equation could describe the oxidation of DMP by UV-H2O2 perfectly, which was strongly affected humic acids in water. The relationship between pseudo-first-order reaction rate and TOC value could be expressed as K = 0.

Improved coreceptor usage prediction and genotypic monitoring of R5-to-X4 transition by motif analysis of human immunodeficiency virus type 1 env V3 loop sequences.

Early in infection, human immunodeficiency virus type 1 (HIV-1) generally uses the CCR5 chemokine receptor (along with CD4) for cellular entry. In many HIV-1-infected individuals, viral genotypic changes arise that allow the virus to use CXCR4 (either in addition to CCR5 or alone) as an entry coreceptor. This switch has been associated with an acceleration of both CD3(+) T-cell decline and progression to AIDS.
