Drought is one of the abiotic stresses limiting the production of soybean(Glycine max).Elucidation of the genetic and molecular basis of the slow-wilting(SW)trait of this crop offers the prospect of its genetic improvement.A panel of 188 accessions and a set of recombinant inbred lines produced from a cross between cultivars Liaodou 14 and Liaodou 21 were used to identify quantitative-trait loci(QTL)associated with SW.Plants were genotyped by Specific-locus amplified fragment sequencing and seedling leaf wilting was assessed under three water-stress treatments.A genome-wide association study identified 26 SW-associated single-nucleotide polymorphisms(SNPs),including three located in a 248-kb linkage-disequilibrium(LD)block on chromosome 2.Linkage mapping revealed a major-effect QTL,qSW2,associated with all three treatments and adjacent to the LD block.Fine mapping in a BC_(2)F_(3) population derived from a backcross between Liaodou 21 and R26 confined qSW2 to a 60-kb interval.Gene expression and sequence variation analysis identified the gene Glyma.02 g218100,encoding an auxin transcription factor,as a candidate gene for qSW2.Our results will contribute significantly to improving drought-resistant soybean cultivars by providing genetic information and resources.

Background and purpose Guidelines recommend dysphagia screening to identify those at high risk of pneumonia.However,little is known about the prevalence and predictors of dysphagia screening and pneumonia among patients with acute ischaemic stroke in China.Methods Using data from the Chinese Stroke Center Alliance,which is a multicentre,prospective,consecutive patient enrolment programme,univariate and multivariate analyses were conducted to identify patient and hospital characteristics associated with dysphagia screening and pneumonia during acute hospitalisation.Results Of 790811 patients admitted to 1476 hospitals,622718(78.7%)underwent dysphagia screening,and 64398(8.1%)developed pneumonia.Patients in stroke units were more likely to be screened for dysphagia than those not in stroke units(OR 1.50;95%CI 1.48 to 1.52),while patients with a past history of stroke were less likely to be screened(OR 0.87;95%CI 0.86 to 0.88).Dysphagia screening(OR 1.46;95%CI 1.30 to 1.65),dysphagia(OR 7.31;95%CI 7.15 to 7.46),and admission to stroke units(OR 1.17;95%CI 1.14 to 1.19)were significantly associated with a greater risk of pneumonia.Conclusions Dysphagia was a critical factor in the development of pneumonia.Nearly one in five patients with acute ischaemic stroke in the Chinese Stroke Center Alliance were not screened for dysphagia.Pneumonia prevention during acute hospitalisation is dependent not only on dysphagia screening but also on the effectiveness of subsequent dysphagia management interventions.Further studies are needed to elucidate the relationship between dysphagia screening,stroke unit care and pneumonia in patients with acute ischaemic stroke.

Lithium-metal anodes(LMAs)have been recognized as the ultimate anodes for next-generation batteries with high energy density,but stringent assembly-environment conditions derived from the poor moisture stability dramatically hinder the transformation of LMAs from laboratory to industry.Herein,an in situ formed cross-linked polymer layer on LMAs is designed and constructed by a facile thiol-acrylate click chemistry reaction between poly(ethylene glycol)diacrylate(PEGDA)and the crosslinker containing multi thiol groups under UV irradiation.Owing to the hydrophobic nature of the layer,the treated LMAs demonstrate remarkable humid stability for more than 3 h in ambient air(70%relative humidity).The coating humid-resistant protective layer also possesses a dual-functional characterization as solid polymer electrolytes by introducing lithium bis(trifluoromethanesulfonyl)imide in the system in advance.The intimate contact between the polymer layer and LMAs reduces interfacial resistance in the assembled Li/LiFePO_(4)or Li/LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)full cell effectively,and endows the cell with an outstanding cycle performance.

In this research study, we have synthesized the bio-capped ZnO/g-C_(3)N_(4) nanocomposites by employing lemon juice(Citrus limon) as a stabilizer and mediator. Fruitfully, lemon juice which contains various acidic functional groups and citric acid has the capability to block the surface of g-C_(3)N_(4) from chemical reactivity and activated the surface of g-C_(3)N_(4) for various reactions. Consequently, the agglomeration behavior and controlled shape of g-C_(3)N_(4) has also been achieved. Our experimental results i.e. XRD,TEM, HRTEM, PL, FS, XPS, and PEC have confirmed that the lemon juice mediated and green g-C_(3)N_(4)(L-CN) have good performances and remarkable visible light photocatalytic activities as compared to the chemically synthesized g-C_(3)N_(4)(CN). Furthermore, the small surface area and low charge separation of g-C_(3)N_(4) is upgraded by coupling with Zn O nanoparticles. It is proved that the coupling of Zn O worked as a facilitator and photoelectron modulator to enhance the charge separation of g-C_(3)N_(4). Compared to pristine lemon-mediated green g-C_(3)N_(4)(L-CN), the most active sample 5Zn O/L-CN showed ~ 5-fold improvement in activities for ciprofloxacin(CIP) and methylene blue(MB) degradation. More specifically,the mineralization process and degradation pathways, and the mineralization process of ciprofloxacin(CIP) and methylene blue(MB) are suggested. Finally, our present novel research work will provide new access to synthesize the eco-friendly and bio-caped green g-C_(3)N_(4)nanomaterials and their employment for pollutants degradation and environmental purification.

Background It remains unclear if intensive antiplatelet and statin treatments begun within 24-72 hours of cerebral ischaemic events from intracranial or extracranial atherosclerosis is effective or safe.Methods The Intensive Statin and Antiplatelet Therapy for High-risk Intracranial or Extracranial Atherosclerosis(INSPIRES)trial is a randomised,double-blind,placebo-controlled,multicentre and 2×2 factorial trial.6100 individuals between the ages of 35 and 80 who have experienced a mild ischaemic stroke or high-risk transient ischaemic attack(TIA)within the previous 72 hours that is attributed to≥50%atherosclerotic stenosis of a major intracranial or extracranial artery or multiple infarctions of atherosclerotic origin will be enrolled in the trial.Eligible subjects will be randomised 1:1:1:1 to one of four groups:(1)intensive antiplatelet therapy(combined clopidogrel and aspirin for days 1-21,then aspirin placebo and clopidogrel for days 22-90)plus immediate intensive statin therapy(atorvastatin at a dose of 80 mg daily for the first 21 days,then 40 mg daily for days 22-90);(2)intensive antiplatelet therapy plus delayed intensive statin therapy(atorvastatin placebo for days 1-3,followed by 40 mg per day of atorvastatin for days 4-90);(3)standard antiplatelet therapy(combination of clopidogrel placebo with aspirin for 90 days)plus immediate intensive statin therapy and(4)standard antiplatelet therapy plus delayed intensive statin therapy.The primary efficacy endpoint is any new stroke(ischaemic or haemorrhagic)within 90 days after randomisation.The primary safety endpoint is moderate to severe bleeding at 90 days.Conclusion The INSPIRES trial will assess the efficacy and safety of intensive antiplatelet therapy and immediate intensive statin therapy begun within 72 hours of onset in decreasing the recurrent stroke at 90 days in patients with acute mild ischaemic stroke or high-risk TIA of intracranial or extracranial atherosclerosis origin.

This study aimed to explore the optimal invisible orthodontic force system during the en-mass distalization of two maxillary molars to minimize the side effect of anchorage loss by changing the direction of the application of the orthodontic force system.A high bio-fidelity 3D finite element model including maxilla,periodontal ligament,dentition,clear aligner,3D anchorage attachment and mini-implant was established.Different lengths of lateral hooks of 3D-printed anchorage attachments and mini-implant positions into the palatal alveolus were considered.A 200 g distal force was applied to the lateral hooks of different horizontal lengths(3.26 mm,6.52 mm and 9.78 mm)with the mini-implant as the application point.Using ABAQUS software,orthodontic tooth movements under 12 different clinical treatment designs were analyzed and calculated.The 3D anchorage attachment enhanced the anchorage of anterior teeth and alleviated the tipping/extrusion of premolars.In contrast to without clear aligners,length of the lateral hook had a negligible effect on both mesial tipping and buccal tipping with clear aligners,which could then be ignored.The change in mesial tipping was less and nearly remained constant despite of the different heights of the mini-implant.The 3D anchorage attachment assisted clear aligner can avoid the side effects of anterior tooth proclination caused by insufficient anchorage.The length of the lateral hook,and height of the mini-implant in this invisible orthodontic force system hardly affects the tooth movement of anchorage units.Clear aligners can effectively control the rotation and tipping of anchorage units caused by 3D anchorage attachment.
