使用CRISPR/CAS9技术对SLMAPK6进行针对性编辑，以促进番茄植物中腋芽的发展
有丝分裂原激活的蛋白激酶（MAPK）级联信号系统在整个真核生物的演化过程中相对保守，并参与了生长，发育和代谢的调节。在这项研究中，矮番茄植物被用作研究材料。首先，通过定量RT-PCR在野生型植物中测量SLMAPK6的组织特异性表达。结果表明，Slmapk6在茎，叶和花的组织中高度表达，但在根，萼片和水果的组织中以低水平表达。第二，Slmapk6-敲除线CRISPR-3和CRISPR-7是通过CRISPR-CAS9技术和农业介导的转换获得的。与野生型相比，突变线CRISPR-3和CRISPR-7显示出显着的表型特征，例如腋窝芽和真实叶子数量增加，茎增厚和更长的传单。In addition, to explore the molecular mechanism by which MAPK regulates axillary bud growth, we also showed that SlMAPK6 positively regulates the strigolactone synthesis genes SlCCD7 and SlCCD8 and the gibberellin (GA) synthesis genes GA20ox3 and GA3ox1 and negatively regulates the axillary bud development-related genes Ls , BL and BRC1b / TCP8和GA合成抑制基因GAI。因此，Slmapk6似乎调节了strigolactone和ga的合成，以诱导番茄腋芽的生长和发育。
评估热电发电厂燃烧发动机中的NOx排放：R和屏幕视图程序的方法
在巴西电基质（2022年为8％）和全球（2021年的61.5％）中存在热电厂。燃烧发动机用于在大多数热电厂中驱动发电机，作为大气发射的主要来源。本研究旨在提出一个模型，允许预先选择这些发动机，并确定最适合获得环境许可的建议标准的模型。使用十二个发动机模型的数据用于评估研究的替代方案。通过R计划利用了计算资源来对数据进行统计分析。与屏幕视图软件的模拟可以调查大气分散场景。研究表明，分散与以下变量具有显着相关性：发射速率，显着性为0.60，烟囱高度为-0.57。It was possible to con- clude that for wind speeds equal to or greater than the local annual average of 2.1 m/s, a distance of 1800 meters to the community (location of the thermal power plant), a flue gas exit speed of 35 m/s, and the analyzed engine standards and design, engines with a NOx emission rate of up to 3.0 g/kWh showed good dispersion values, below 200 mg/Nm 3 of NOx, the standard required by巴西环境立法。因此，只有四个引擎模型符合此条件。
开发与磷酸氧化物部分芳族聚酰胺的阻燃溶液
由于其出色的热稳定性而部分芳香的聚酰胺被广泛用于高温应用中，但是，就像其脂肪族对应物一样，它们很容易易燃且更具挑战性的处理。在这项工作中，合成了几种有机磷的阻燃剂并与部分芳香的聚酰胺合成并复杂化，并评估其可加工性，热和火行为。The compounds containing a commercial flame retardant, Exolit ® OP 1230 (EX), and two new flame retardants, namely 1,4-phe nylenebis(diphenylphosphine oxide) (MP) and (1,1 ′ -biphenyl]-4,4 ′ -diylbis(diphenylphosphine oxide) (BP), showed self-extinguishing与原始PAP相对于原始PAP，功能（即UL94 V0类）具有4 wt％磷（P）的载荷，以及PHRR的实质性降低（最高47％）使用扩展时间尺度上的流变学测量来评估部分芳香族聚酰胺化合物的熔体稳定性。聚合物基质中MP和BP的存在不会触发任何过度的降解现象，例如链条分支，分支或交联反应，从而允许与原始芳族芳族聚酰胺样品相似的稳定加工性。最后，对热分解过程中进化气体的分析表明，在分解过程的早期，MP和BP在很早的早期就发挥着火焰抑制作用。

Fax: 585-276-2576 23 24 Abstract 25 Septin expressions are altered in cancer cells and exhibit poor prognoses in malignancies. As the 26 first approach to develop a septin filament targeting agent, we optimized the structure of 27 Forchlorfenuron (FCF), a known plant cytokinin to generate UR214-9, which contrary to FCF, 28 causes septin-2/9 filamental structural catastrophe in cancer cells without altering cellular septin 29 protein levels. In-silico docking using septin-2/septin-2 dimer complex showed that UR214-9 30 displaced the guanine carbonyl oxygen from the GDP binding domain and showed increased 31 binding energy than FCF(-8.59vs-7.21). UR214-9 reduced cancer cell growth, downregulated 32 HER2/STAT-3 axis and controlled growth of HER2+ pancreatic, breast and ovarian cancer 33 xenografts in NSG mice and enhanced response of Herceptin against HER2+breast cancer 34 xenograft. Transcriptome analysis of UR214-9 exposed cells demonstrated significant 35 perturbation of <20 genes compared to afatinib which impacted >1200 genes in JIMT-1 breast 36 cancer cells indicating target specificity and non-transcriptional functions of UR214-9. In summary, 37 disrupting septins via UR214-9 is a new approach to control the growth of HER2+ malignancies. 38 39 Introduction 40 41 Septins are a family of GTP-binding cytoskeletal proteins that participate in cytokinesis, 42 cell migration, chromosomal dynamics and protein secretion. Septins hetero-oligomerize to 43 generate scaffolding filaments, bundles, and rings within cells 1-11 . Additionally, septins are a 44 critical cytoskeletal component that regulate the function of tubulin and actin. Altered septin 45

ABSTRACT Background: Delayed diagnosis and inadequate treatment caused by limited biomarkers are associated with the outcomes of COVID-19 patients.有必要确定其他有希望的生物标志物和候选靶标，以定义失调的炎症状态。Methods: The triggering receptors expressed on myeloid cell (TREM)-1 and TREM-2 expression from hospitalized COVID-19 patients were characterized using ELISA and flow cytometry, respectively.评估了它们与疾病严重程度的相关性，并与主要的临床指标进行了对比。结果：与对照组相比，发现Covid-19患者血浆中可溶性TREM-1和TREM-2的表达增加。Moreover, membrane-bound TREM-1 and TREM-2 expression was upregulated on the cell surface of circulating blood T cells from COVID-19 patients.Correlation analysis showed that sTREM-2 levels were negatively correlated with PaO 2 /FiO 2 , but positively correlated with C-reactive protein (CRP), procalcitonin (PCT) and interleukin (IL)-6 levels.Receiver operating characteristic curve analysis indicated that the predictive efficacy of sTREM-1 and sTREM-2 was equivalent to CRP and IL-6, and a little better than absolute leukocyte or neutrophil count and PCT in distinguishing disease severity.Conclusion: TREM-2 and TREM-1 are critical host immune factors that response to SARS-COV-2 infection and could serve as potential diagnostic biomarkers and therapeutic targets for COVID-19.
研究Maillard产品对病原体微生物的抗菌作用
我们的发现表明，使用的氨基酸类型，具体取决于其离子结构，序列和氨基酸组成，分子修饰和分子相互作用，会影响Maillard产物的抗菌群特性[27]。这些产物由不同的组合（黑色素素）制成，并且具有不同的能力以抑制致病性微生物的生长。是黑色素蛋白的抗虫骨质特性变化的潜在原因之一。的确，Mela Noidin的抗菌活性可能与其结构相关。黑色素素是一种复杂的聚合物，具有未知确切的结构，但是与细菌膜损伤相关的金属螯合可能是其抗菌活性背后的机制。我们假设用来制造Mela Noidin的氨基酸类型会影响其螯合物的能力。金属离子和聚二烯在螯合期间建立坐标，其中一些循环分组的原子三明治金属原子在其中形成螯合络合物。The hemolytic effect of the different concentration of three combination of the Maillard products (Gly-Glu), (Val-Glu) and (Try-Glu) (Figure 4) showed that these all products present a very weak toxic effect on isolated erythrocytes, with a rate of hemolysis that does not exceed 12.09 % at a hight concentration of MRPs tested of 390 mg/ml compared to the total hemolysis.of positive 控制。它们可能是治疗和药理的非常重要的来源。

低价锰原子在陶瓷上稳定为一氧化二氮合成
心肌和心律不齐的纤维化变化代表系统性硬化症（SSC）的致命并发症，但是基本机制仍然难以捉摸。小鼠过度表达转录因子FOSL-2（FOSL-2 TG）代表SSC的动物模型。Fosl-2 tg mice showed interstitial cardiac fi brosis, disorganized connexin-43/40 in intercalated discs and deregulated expression of genes controlling conduction system, and developed higher heart rate (HR), prolonged QT intervals, arrhythmias with prevalence of premature ventricular contractions, ventricular tachycardias, II-degree atrio-ventricular blocks并降低了人力资源变异性。用异丙肾上腺素FOSL-2 TG小鼠刺激后，HR反应受损。与FOSL-2 TG相比，免疫dim dim rag2 - / - fosl-2 tg小鼠受到增强的心肌纤维化和ECG异常的保护。转录组学分析表明，FOSL-2-ERVERSESS是造成心脏纤维细胞的纤维性特征的原因，而FOSL-2 TG小鼠中的炎症成分激活了它们的纤维性和心律失常的作用表型。在人类心脏纤维细胞中，FOSL-2超过表达增强了肌纤维细胞的签名，在proinmotal或pro粘连刺激下。这些结果表明，在免疫性条件下，转录因子FOSL-2夸大了肌纤维纤维肌，心律不齐和对压力的异常反应。

对机器人技术的认识、态度和知识......
The aim of this study was to assess the awareness, attitude, and knowledge of Robotic technologies used in neurorehabilitation among Physiotherapy interns and Professionals across Maharashtra. A cross-sectional study was conducted in tertiary care hospitals and colleges in Maharashtra, India, using a self-made questionnaire. The results showed that 63% of the individuals are moderately aware, 67% have a positive outlook on the implementation of such advances but only 7.5% have accurate knowledge of the technology and its uses. Most of the participants also believe that Robotic Rehabilitation can be very time effective and reduce the load of the therapist as well as play a very important role in aiding neuroplasticity after rehabilitation. The study demonstrated that a higher degree of understanding and a more positive attitude regarding the application of Robotic Rehabilitation follow from heightened awareness of this field. Enhanced training programs, better integration of technology into rehabilitation practices, addressing time constraints and workload prioritization, and most importantly, overcoming economic barriers will ensure the effective implementation of Robotic therapies for the benefit of the patient and society as a whole. This will revolutionize the field of Physiotherapy and rehabilitation, offering new avenues for improving treatment outcomes and advances in clinical practice. The study concluded that, it is important to generate or enhance awareness towards the most-advancing fields and the uses of Robotic technology in neurological conditions in clinical practice which empowers Physiotherapy to adapt to the changing landscape of healthcare and deliver high-quality, patient-centered care.
