Green Analytical Chemistry, Год журнала: 2022, Номер 3, С. 100036 - 100036

Опубликована: Окт. 1, 2022

The global concern about the fate of plastic particles, including microplastics (MPs) and nanoplastics (NPs), in aquatic ecosystems has undoubtedly grown as million tons polymeric fragments are released oceans an annual basis. ability these items being transferred into several combination with their to absorb organic or inorganic pollutants onto surface, raises need for a sufficient monitoring MPs/NPs complex environmental matrices. In frame these, microscopic techniques considered ideal tools critically assist other analytical due fast-screening character even complete detailed analysis particles some cases. light above, present review discusses group used isolated from samples most likely be important future actions, emphasizing on operating fundamentals, merits limitations. Moreover, highlighted green particles/fragments minimum reagents, solvents, energy required implementation such kind analysis. Finally, effective spectroscopic ones also presented.

One of the main aims green analytical chemistry (GAC) is reduction solvents and chemicals consumed. Recycling mobile phase in chromatographic techniques provides an efficient way to implement GAC principles. However, this not easy job, particularly case gradient mode. Analysis multi-pharmaceuticals for same manufacturer using one system dramatically reduces consumed solvents, time, cost pharmaceuticals analysis quality control laboratories. This work attempt reduce effort needed several dosage forms produced by manufacturer. Our novel RP-HPLC method able separate quantify a tertiary mixture piracetam, ketoprofen omeprazole manufacturers. The analyst can easily three drugs run elution mode methanol water (from 50% 85% ten minutes) with flow rate 1.5 mL min-1 on non-polar C18 column. Suitable dilutions were done working solution mixed pharmaceutical formulations prior analysis. procedure will save time money during calibration ranges are (5-25), (5-25) (3-20) μg mL-1 studied drugs. International Council Harmonization (ICH) procedures followed validation process results evaluated comparison official HPLC methods, where no noteworthy differences found. profile pictograms AGREE Green Analytical Procedure Index (GAPI) approaches proved eco-friendly character simultaneous quantitative Stimulan® Hyposec® capsules, Ketolgin® tablets from Amoun Pharmaceutical Company, Egypt, be accomplished via method. Also, Memoral® ampoules, Topfam® tablets, Gastroloc® capsules Sigma Industries, could analyzed simultaneously. Omez® Ketogesic® Pharaonia Pharmaceuticals, determined simultaneously too.

Recent Developments and Application of Mass Spectrometry Imaging in N-Glycosylation Studies: An Overview

Mass Spectrometry, Год журнала: 2024, Номер 13(1), С. A0142 - A0142

Опубликована: Фев. 9, 2024

Among the most typical posttranslational modifications is glycosylation, which often involves covalent binding of an oligosaccharide (glycan) to either asparagine (N-linked) or a serine/threonine (O-linked) residue. Studies imply that N-glycan portion glycoprotein could serve as particular disease biomarker rather than protein itself because N-linked glycans have been widely recognized evolve with advancement tumors and other diseases. N-glycans found on sites especially significant. Since play clearly defined functions in folding proteins, cellular transport, transmission signals, them linked several illnesses. However, these N-glycans' production not template driven, they substantial morphological range, rendering it difficult distinguish species are relevant biology medicine using standard techniques. Mass spectrometry (MS) techniques emerged effective analytical tools for investigating role glycosylation health illness. This due developments MS equipment, data collection, sample handling By recording spatial dimension glycan's distribution
