Plants experience different abiotic/biotic stresses,which trigger their molecular machinery to cope with them. Besides general mechanisms prompted by many stresses, specific mechanisms have been introduced to optimize the response to individual threats. however, these key mechanisms are difficult to identify. here, we introduce an in-depth species-specific transcriptomic analysis and conduct an extensive meta-analysis of the responses to related species to gain more knowledge about plant responses. The spider mite Tetranychus urticae was used as the individual species, several arthropod herbivores as the related species for meta-analysis, and Arabidopsis thaliana plants as the common host. The analysis of the transcriptomic data showed typical common responses to herbivory, such as jasmonate signaling or glucosinolate biosynthesis. Also, a specific set of genes likely involved in the particularities of the Arabidopsis-spider mite interaction was discovered. The new findings have determined a prominent role in this interaction of the jasmonateinduced pathways leading to the biosynthesis of anthocyanins and tocopherols. Therefore, tandem individual/general transcriptomic profiling has been revealed as an effective method to identify novel relevant processes and specificities in the plant response to environmental stresses.

Chemical absorption is a crucial step for several chemical processes such as ammonia production, coal gasification, methane reforming,ethylene oxide manufacturing and treatment of associated gas streams [1]. It is considered one of the main processes to eliminate CO_2 emissions from power plants by *** of new solvents are of high interest in chemical absorption for carbon capture. For the design of the absorption and desorption columns it is essential to know the vapour-liquid equilibrium(VLE), heat of absorption and densities. N,N-diethylethanolamine(DEEA) appeared as one of the amines with the lowest amount of energy needed for its regeneration [2], which would directly decrease the operation costs. DEEA has a high CO_2 loading of 1 mol/mol of amine compared to the traditional mEA solvent(0.5 mol/mol amine) and is obtained from renewable sources[1]. The main weakness is its low absorption rate and consequently the use of promoters is *** this work, a thermodynamic model based on the electrolyte non-random two-liquid theory(eNRTL) was created and fitted to correlate and predict the partial and total pressures of the unloaded and loaded aqueous DEEA solutions. New interaction parameters were obtained for the binary and tertiary system. This model represents the vapour pressures of the pure components, DEEA and h_2 O, with AARD of 1.9% and 1.73%respectively. Furthermore, the fitted model predicts the total pressure above the binary system, h_2O-DEEA, with AARD of 0.05%. The excess of enthalpy and densities are predicted with AARD of 5.63% and 1.38% respectively. The tertiary system, h_2O-DEEA-CO_2, is fitted for 2 m and5 m DEEA solutions with loading between 0.042 and 0.9 mol CO_2/mol amine up to 80 ℃. Results of CO_2 partial pressures and total pressures are reproduced, with AARD of 19.45% and 16.18% respectively. Densities are predicted with an AARD of 1.52%.

Ag2S nano dots have already bee n dem onstrated as promisi ng n ear-i nfrared (NIR-II, 1.0-1.45 pm) emitting nan oprobes with low toxicity, high penetration and high resolution for in vivo imaging of, for example, tumors and vasculature. In this work, we have systematically investigated the pote ntial applicati on of function alized Ag2S nano dots for accurate imaging of damaged myocardium tissues after a myocardial in farction in duced by either partial or global ischemia. Ag2S nano dots surface-function alized with the an giote nsin II peptide (ATI I) have show n over 10-fold enhanced binding efficiency to damaged tissues than non-specifically (PEG) functionalized Ag2S nanodots due to their interaction with the upregulated angiotensin II receptor type I (AT1R). It is demonstrated how the NIR-II images generated by ATII-functionalized Ag2S nanodots contain valuable information about the location and extension of damaged tissue in the myocardium allowing for a proper identification of the occluded artery as well as an in direct evaluati on of the damage level. The pote ntial applicati on of Ag2S nano dots in the n ear future for in vivo imaging of myocardial infarction was also corroborated by performing proof of concept whole body imaging experiments.

Background: Associative data and some controlled studies suggest that the inflammatory cytokine tumor necrosis factor(TNF) α can induce fatty liver in dairy cattle. however, research demonstrating that TNFα is a necessary component in the etiology of bovine fatty liver is lacking. The aim of this work was to evaluate whether blocking TNFα signaling with a synthetic cyclic peptide(TNF receptor loop peptide; TRLP) would improve liver metabolic function and reduce triglyceride accumulation during feed ***: Capability of TRLP to inhibit TNFα signaling was confirmed on primary bovine hepatocytes treated with recombinant bovine TNFα and 4 doses of TRLP(0, 1, 10, 50 μmol/L) over 24 h. Next, 4 lactating holstein cows(parity 1.4 ± 0.5, 433 ± 131 d in milk) in an incomplete Latin rectangle design(3 × 2) were subcutaneously administered with different TRLP doses(0, 1.5, 3.0 mg/kg BW) every 4 h for 24 h, followed by an intravenous injection of TNFα(5 μg/kg BW). Before and for 2 h after TNFα injection, TRLP decreased plasma non-esterified fatty acid(NEFA)concentration(P ≤ 0.05), suggesting an altered metabolic response to inflammation. Finally, 10 non-pregnant, nonlactating holstein cows(3.9 ± 1.1 yr of age) were randomly assigned to treatments: control(carrier: 57% DmSO in PBS)or TRLP(1.75 mg TRLP/kg BW per day). Treatments were administrated every 4 h for 7 d by subcutaneous injection to feed-restricted cows fed 30% of maintenance energy requirements. Daily blood samples were analyzed for glucose,insulin, β-hydroxybutyrate, NEFA, and haptoglobin concentrations, with no treatment effects detected. On d 7, cows completed a glucose tolerance test(GTT) by i.v. administration of a dextrose bolus(300 mg glucose/kg BW). Glucose,insulin, and NEFA responses failed to demonstrate any significant effect of treatment during the GTT. however, plasma and liver analyses were not indicative of dramatic lipolysis or hepatic lipidosis, suggesting that the feed restriction protoc

水生-陆地系统补贴形成的联结作用在构建群落和调节生态系统功能方面发挥重要作用。在营养贫瘠的生态系统中(例如密歇根湖周围的淡水沙丘),水生-陆生系统补贴显得尤为重要。春季成年螺在密歇根湖涌出,成群交配,然后死亡。蠓尸体在植物的基部形成土丘状,通过输入营养提高植物的生产力。然而,水生-陆地系统补贴对植物生产力的影响可能取决于其他生物的交互作用,特别是土壤微生物可能通过促进养分转化为植物可利用的形式或与植物竞争养分而发挥关键作用。在温室实验中,我们检验了湖生蠓(Chironomidae)的尸体和土壤微生物如何独立和相互影响一种常见沙丘草(沙拂子茅,Calamovilfa longifolia)的生长表现。为确定蠓是否影响土壤非生物特性,我们检验了添加蠓如何影响土壤养分和土壤湿度。研究结果显示,煖极大地增加了植物生物量,但其效应的大小受土壤微生物的影响。在没有土壤微生物的情况下,添加壕的植物生物量比没有添加的高7倍,而在有土壤微生物的情况下,植物生物量提高了3倍。蠓对植物生长的促进作用可能由于它们向土壤中输入养分所导致,因为与沙丘土壤相比,蠓的氮、磷、钾含量分别高100倍、10倍和150倍。我们的研究结果表明,土壤微生物可能与植物竞争这些养分。总之,我们发现蠓是重要的水生-陆地系统补贴,对密歇根湖沿岸植物生产力产生强烈和正向的影响,但水生-陆地系统补贴作用必须在生态群落内发生的复杂相互作用的背景下考虑。
