Inborn errors of metabolism (IEM) lead to the physical and mental disability and death of infants, which can be prevented if treated early. Hence it is imperative in diagnosing these disorders at the earliest. The study is planned to differentiate suspected IEM by quantifying the lactate-pyruvate ratio (L/P ratio), Amino acid profiling by HPLC in addition to blood ammonia using the basic methodology in comparison to globally accepted mass spectroscopy technique and specific enzyme activity assays. The objective of this study is not to compete with the existing gold standard methodology rather makes the best of basic diagnostic modalities available. Five cases out of 100 referred cases of IEM suspicion showed the altered pattern of Aminogram correlating with high L/P ratio and Hyperammonemia, which were positive cases, as confirmed by the clinician who referred. Hence study parameters could be used as preliminary protocol to investigate and screen the IEM.

Selenium promotes plant growth and improves nutritional quality, and the role of nano-selenium in alfalfa in regulating nutritional quality is unknown. In this study, using the N labeling method, it was found that nano-selenium could promote plant nitrogen metabolism and photosynthesis by increasing the light energy capture capacity and the activities of key enzymes of the nitrogen metabolism process, leading to an increase in alfalfa nitrogen accumulation and dry matter content. The transcriptome and metabolome revealed that nano-selenium mainly affected the pathways of 'biosynthesis of amino acids', 'starch and sucrose metabolism', 'pentose and glucuronate interconversions', 'pentose phosphate pathway', and 'flavonoid biosynthesis'.

Background: Despite numerous genetic studies on Infectious Bronchitis Virus (IBV), many strains from the Middle East remain misclassified or unclassified. Genotype 1 (GI-1) is found globally, while genotype 23 (GI-23) has emerged as the predominant genotype in the Middle East region, evolving continuously through inter- and intra-genotypic recombination. The GI-23 genotype is now enzootic in Europe and Asia.

The extensive presence of per-/polyfluoroalkyl substances (PFASs) in the environment and their adverse effects on organisms have garnered increasing concern. With the shift of industrial development from legacy to emerging PFASs, expanding the understanding of molecular responses to legacy and emerging PFASs is essential to accurately assess their risks to organisms. Compared with traditional toxicological approaches, omics technologies including transcriptomics, proteomics, metabolomics/lipidomics, and microbiomics allow comprehensive analysis of the molecular changes that occur in organisms after PFAS exposure.
