Buas-Buas(Premna serratifolia)从浸润,渗透和净化中叶提取物已被证明是α-葡萄糖苷酶抑制剂。由于尚未进行α-葡萄糖苷酶抑制剂的植物化学成分的努力,因此需要进行一项研究,以确定已在体外和硅中证明的活性的负责任化合物。利用柱色谱法和半程释放性高性能液相色谱法(HPLC)的乙酸乙酯馏分分离活性化合物具有最佳的抑制作用。 通过超高的液相色谱 - Q精确杂交四极杆 - 轨道高分辨率高分辨率质谱法(UHPLC-Q-Q-orbitrap HRMS)研究了分离株的化合物。 通过使用N末端麦芽糖酶 - 葡萄糖氨基酶的分子对接[蛋白质数据库(PDB)代码:2QMJ],C-末端麦尔氨酸酶 - 糖 - 葡萄糖酶(PDB代码:PDB代码:3top)和Isomaltase(Pdbb code)(pDABB代码),研究了α-葡萄糖苷和活性化合物的相互作用。 Analyzed by UHPLC-Q-Orbitrap HRMS, nine flavonoids were detected, which are centaureidin, chrysin, pectolinaringenin, glycitein, kaempferide, syringetin, tricin, casticin, and 3,5,4ʹ-trimethoxy- 6,7-methylenedioxyflavone (estimated to be a new 化合物)。 casticin – 2qmJ,Tricin – 3top和Centaureidin – 3A4A复合物的结合能较低,为-5.29,-6.77,和-8.02 kcal/mol和-8.02 kcal/mol和抑制常数(Ki),为131.54、10.89、10.89,和0.34、10.89,和0.34 µmmm,perequentimal sequentimal µmmm,sequentially。利用柱色谱法和半程释放性高性能液相色谱法(HPLC)的乙酸乙酯馏分分离活性化合物具有最佳的抑制作用。通过超高的液相色谱 - Q精确杂交四极杆 - 轨道高分辨率高分辨率质谱法(UHPLC-Q-Q-orbitrap HRMS)研究了分离株的化合物。通过使用N末端麦芽糖酶 - 葡萄糖氨基酶的分子对接[蛋白质数据库(PDB)代码:2QMJ],C-末端麦尔氨酸酶 - 糖 - 葡萄糖酶(PDB代码:PDB代码:3top)和Isomaltase(Pdbb code)(pDABB代码),研究了α-葡萄糖苷和活性化合物的相互作用。Analyzed by UHPLC-Q-Orbitrap HRMS, nine flavonoids were detected, which are centaureidin, chrysin, pectolinaringenin, glycitein, kaempferide, syringetin, tricin, casticin, and 3,5,4ʹ-trimethoxy- 6,7-methylenedioxyflavone (estimated to be a new 化合物)。casticin – 2qmJ,Tricin – 3top和Centaureidin – 3A4A复合物的结合能较低,为-5.29,-6.77,和-8.02 kcal/mol和-8.02 kcal/mol和抑制常数(Ki),为131.54、10.89、10.89,和0.34、10.89,和0.34 µmmm,perequentimal sequentimal µmmm,sequentially。
ycoplasma pneumoniae is a common etiologic agent of community-acquired pneumonia (CAP) among children. Although M. pneumoniae infection often causes a mild and self-limiting dis- ease, pneumonia develops in ≈ 10%–20% of pediatric patients ( 1 ). First-line therapies for M. pneumoniae infection are based on macrolides, a group of anti- microbial drugs widely used in outpatient settings because of their high oral bioavailability. However, overuse and indiscriminate use of macrolides have contributed to the emergence of macrolide-resistant M. pneumoniae (MRMP). Point mutations in the V region of the M. pneumoniae 23S rRNA gene have been associated with macrolide resistance ( 2 ). In recent years, prevalence of MRMP has increased and is very high in Asia (13.6%–100%) ( 2 – 4 ). Dur- ing spring/summer 2023, hundreds of children with CAP were admitted daily to each of the major hospi- tals in Hanoi, Vietnam. M. pneumoniae has emerged as the major pathogen detected in approximately one third of patients with CAP (5). We analyzed the mutations in the 23S rRNA gene of M. pneumoniae isolated from nasopharyngeal samples of pediatric CAP patients during the 2023 outbreak in Vinmec Times City Hospital, Hanoi.

摘要Siddha系统是印度南部的传统系统,尤其是在泰米尔纳德邦。thylam(药油)是32种内部药物之一。karunkozhi thylam(KKT)用于治疗vatha病(退化性疾病)。定性和定量分析可确保药物的质量和安全性,并最大程度地减少污染和掺假风险。Weight/ml, refractive index (RI), density, iodine value (IV), acid value (AV) were analyzed as standardization parameter and GC-MS were employed to identify the active compound and test for heavy metals (lead, cadmium, mercury, arsenic), microbial contamination, test for specific pathogen (E.coli, Salmonella spp., Staphylococcus aureus,铜绿假单胞菌),农药残留(有机氯,有机磷,拟除虫菊酯),黄曲霉毒素的测试(B1,B2,G1,G1)用作安全措施。结果表明RI为1.457,密度为1.213g/cm 3,IV为108.12g I/100g,AV为0.86mg KOH/g。安全参数在可接受的限制之内。GC-MS显示具有抗炎活性的油酸和N-六核酸的存在。本研究为KKT建立了标准化协议,以确保质量,安全性和功效。这些发现对法规合规性具有重要意义,并提出了进一步研究的领域。
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。
