非酒精性脂肪肝（NAFLD）是最常见的慢性肝病，是从脂肪堆积到变性炎症，并出现非酒精性脂肪性肝炎（NASH），直至引发肝纤维化、肝硬化甚至肝癌的一系列过程。非酒精性脂肪目前已经是全球感染人群占比最大的肝病且发病率逐年上升。非酒精性脂肪肝是一种新陈代谢紊乱的疾病，但它也涉及多种免疫细胞介导的炎症过程，通过分泌促炎和/或抗炎因子来促进和/或抑制肝细胞炎症，从而影响非酒精性脂肪肝的进程。然而，其潜在的疾病机制及其在免疫细胞中的作用仍在研究之中，留下了许多悬而未决的问题。因此，在这篇综述中，我们介绍了免疫细胞在非酒精性脂肪肝的发病和致病过程中相互作用的最新概念。我们还重点介绍了在非酒精性脂肪肝中表现出具有治疗意义的免疫学特性的特定非免疫细胞，以便更好地了解表现出治疗特性的免疫/非免疫细胞的作用机制，从而在未来设计出治疗非酒精性脂肪肝的创新性和更具特异性的药物。

Validation of a method for Characterization of Ethanol in Water by HS-GC-FID to Serve the Traceability of Halal measurements

引用

Green and Sustainable Chemistry 2024年第2期14卷 17-28页

作者： Adel B. Shehata Abdulrahman R. Al Askar mohammed A. Al rasheed Abdulrahman m. Al Zahrany Fahd A. Al Kharraa Sowailem A. Al Sowailem Chemistry Department/National measurement and Calibration Center (NmCC) Saudi Standards Metrology and Quality Organization (SASO) Riyadh Kingdom of Saudi Arabia

The determination of the ethanol content in food products is of fundamental importance for HALAL certification. In this work, an analytical method for the determination of ethanol in water by headspace gas chromatography with flame ionization detector (HS-GC-FID) has been developed and validated for the use in characterization of ethanol reference materials. The validation study was carried out in the linear calibration range 100 - 1500 mg/kg using the NIST SRm 2900, nominal 95.6%. The studied performance characteristics of the method were the limit of detection, LOD, the limit of quantification LOQ, selectivity, linearity, precision, recovery and bias. The validation results showed that the method is selective, precise, accurate and free from any significant bias. The LOD and LOQ were 1.27 and 3.86 mg/kg respectively and the estimated expanded uncertainty was 2% indicating that the method is fit for the purpose of certification of ethanol in water reference materials.
