摘要:镰刀菌疫病(FHB)和镰刀冠腐烂(FCR)由咪唑杀真菌剂的应用管理,如欧洲绿色交易所述,这些杀菌剂将在2030年受到严格限制。在这里,通过遵循循环经济的原理,提出了一种新颖和生态可持续的纳米结构颗粒制剂(NPF)。纤维素纳米晶体(CNC)和抗性淀粉是从高淀粉(HA)面包小麦的麸皮中获得的,并用作载体和赋形剂,而壳聚糖和长石酸则作为抗真菌和抗真菌和INICITOTITRITITITOR主动原理功能化。NPF抑制了分生孢子发芽和菌丝体的生长,并与分生孢子机械相互作用。NPF在易感面包小麦基因型中最佳降低了FHB和FCR症状,同时在植物上具有生物相容性。The expression level of 21 genes involved in the induction of innate immunity was investigated in Sumai3 (FHB resistant) Cadenza (susceptible) and Cadenza SBEIIa (a mutant characterized by high-amylose starch content) and most of them were up-regulated in Cadenza SBEIIa spikes treated with the NPF, indicating that this genotype may possess an interesting genomic background particularly对诱导剂样分子的反应。量化表明NPF控制的FHB扩散,而Cadenza Sbeiia对FCR真菌扩散具有抗性。目前的研究工作强调,NPF是FHB可持续管理的强大武器,而Cadenza Sbeiia的基因组应深入研究,因为对类似Esicor的分子和对FCR真菌差的耐药性特别敏感。
Therapy resistance has long been considered to occur through the selection of pre-existing clones equipped to survive and quickly regrow, or through the acquisition of mutations during chemotherapy. Here we show that following in vitro treatment by chemotherapy, epithelial breast cancer cells adopt a transient drug tolerant phenotype characterized by cell cycle arrest, epithelial-to-mesenchymal transition (EMT) and the reversible upregulation of the multidrug resistance (MDR) efflux transporter P-glycoprotein (P-gp). The drug tolerant persister (DTP) state is reversible, as cells eventually resume proliferation, giving rise to a cell population resembling the initial, drug-naïve cell lines. However, recovery after doxorubicin treatment is almost completely eliminated when DTP cells are cultured in the presence of the P-gp inhibitor Tariquidar. Mechanistically, P-gp contributes to the survival of DTP cells by removing reactive oxygen species-induced lipid peroxidation products resulting from doxorubicin exposure. In vivo, prolonged administration of Tariquidar during doxorubicin treatment holidays resulted in a significant increase of the overall survival of Brca1 − / − ;p53 − / − mammary tumor bearing mice. These results indicate that prolonged administration of a P-gp inhibitor during drug holidays would likely benefit patients without the risk of aggravated side effects related to the concomitantly adminis tered toxic chemotherapy. Effective targeting of DTPs through the inhibition of P-glycoprotein may result in a paradigm shift, changing the focus from countering drug resistance mechanisms to preventing or delaying therapy resistance.
亚硝酸盐氧化细菌(NOB)是重要的硝酸盐,其活性调节了亚硝酸盐的可用性,并决定了生态系统中氮损失的幅度。In oxic marine sediments, ammonia- oxidizing archaea (AOA) and NOB together catalyze the oxidation of ammonium to nitrate, but the abundance ratios of AOA to canonical NOB in some cores are signi fi cantly higher than the theoretical ratio range predicted from physiological traits of AOA and NOB characterized under realistic ocean conditions, indicating that some NOBs are yet to be发现。在这里,我们报告了硝基氨叶甲状腺素的细菌门,其成员比规范的NOB更丰富,并且在整个全球寡营养沉积物中广泛存在。ca。硝基氨基甲酸糖构件具有氧化亚硝酸盐的功能潜力,此外还具有其他辅助功能,例如尿素水解和硫代硫酸盐还原。虽然一个回收的物种(Ca。硝基氨基甲磷酸菌)通常在塞毒区内构建,另一个(Ca。硝基氨基甲状腺素)还出现在缺氧的沉积物中。计数CA。 硝酸二氨基糖作为亚硝酸盐氧化剂有助于解决氧化海洋沉积物中AOA和NOB之间明显的丰度失衡,因此其活性可能对亚硝酸盐预算施加控制。计数CA。硝酸二氨基糖作为亚硝酸盐氧化剂有助于解决氧化海洋沉积物中AOA和NOB之间明显的丰度失衡,因此其活性可能对亚硝酸盐预算施加控制。
