Objective: To identify the origin of Flos Chrysanthemi.
Methods: FTIR (Fourier transform infrared spectroscopy) and SIMCA (sofe independent modeling of class analogy).
Results: The correctness of every classification was higher than 60%.
Conclusion: This approach was proved to be a reliable and practicable method for the discrimination of geographical origin of Chrysanthemum.

Delving into knowing the blackfly (Diptera: Simuliidae) species composition of Spain and their ecological requirements is crucial, due to their instrumental role in natural food webs as intermediaries in the flow of energy in aquatic ecosystems, and because of the haematophagic behaviour displayed by females of several species. The present study has analysed the abundance and distribution of the larvae and pupae of blackfly species in 105 sampling stations located in lotic water bodies of the provinces of Ávila, Salamanca, and Zamora of the Tormes River basin. The study has allowed to identify 24 species: 17 from Ávila, 13 from Salamanca, and seven from Zamora, classified in three genera (Metacnephia, Prosimulium, and Simulium), and five subgenera (Boophthora, Eusimulium, Nevermannia, Simulium, Wilhelmia).

Burkholderia pseudomallei, a soil-borne bacterium that causes melioidosis, endemic in South and Southeast Asia and northern Australia, is now emerging in new regions. Since the 1990s, cases have been reported in French overseas departments, including Martinique and Guadeloupe in the Caribbean, and Reunion Island and Mayotte in the Indian Ocean, suggesting a local presence of the bacterium. Our phylogenetic analysis of 111 B.

Introduction: Modifiable Areal Unit Problems are a major source of spatial uncertainty, but their impact on infectious diseases and epidemic detection is unknown.
Methods: CMS claims (2016-2019) which included infectious disease codes learned through Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) were extracted and analysed at two different units of geography; states and 'home to work commute extent' mega regions. Analysis was per member per month.

Rationale: The analysis of natural abundance isotopes in biogenic NO molecules provides valuable insights into the nature of their precursors and their role in biogeochemical cycles. However, current methodologies (for example, the isotopocule map approach) face limitations, as they only enable the estimation of combined contributions from multiple processes at once rather than discriminating individual sources. This study aimed to overcome this challenge by developing a novel methodology for the partitioning of NO sources in soil, combining natural abundance isotopes and the use of a N tracer (N Gas Flux method) in parallel incubations.

In this study, a robust and validated UHPLC-QqQ-MS/MS method was developed to quantify anserine and carnosine levels and their ratios to distinguish the geographical origin of red seabream (Pagrus major) from Japan and Korea. Comprehensive optimization of column types, mobile phase pH, organic solvent ratios, and internal standards identified the optimal conditions: an HILIC column at pH 5 with 75 % acetonitrile and PEH as the internal standard. The method exhibited excellent sensitivity, linearity, accuracy, and precision, establishing anserine as the most reliable biomarker for origin discrimination.
