Human alpha 1-acid glycoprotein (AGP), also known as orosomucoid, is a major acute-phase plasma protein. The amino acid sequence of AGP, which was determined by sequencing from protein isolated from pooled plasma, contained amino acid substitutions in 21 different positions. Genomic and cDNA clones which correspond to one of the possible amino acid sequences have been previously reported. In this paper we present the complete nucleotide sequence of a second gene, AGP2 which is located approx. 3.3 kb downstream from AGP1. The derived amino acid sequence of AGP2 contains 19 of the possible alternative amino acid substitutions as well as two additional differences. It is clear from the results presented here that the AGP in human plasma is the product of two separate gene loci.

In metabolomic studies, sample collection and analysis are typically performed at separate locations, necessitating the transport and storage of samples. However, sample transport and storage conditions are often constrained by the available facilities. Specifically, metabolite levels in biological and food samples can fluctuate due to the activity of endogenous enzymes, depending on the transport and storage conditions.

Background And Aims: To assess the associations between serum concentrations of branched-chain amino acids (BCAAs)-valine, leucine, and isoleucine-and different anthropometric markers, including leptin and adiponectin levels, as well as body composition.
Methods And Results: This cross-sectional study used data from the CoLaus|PsyCoLaus and the OsteoLaus studies in Lausanne, Switzerland. Anthropometric markers included the conicity index (CI), body roundness index (BRI), a body shape index (ABSI), body mass index (BMI), and waist circumference, among others.

Huangjiu, a traditional alcoholic beverage, presents a complex fermentation ecosystem primarily influenced by specific fungal species. This study utilized a culture-dependent approach and amplicon sequencing to explore fungal community succession during Huangjiu fermentation. Key fungi identified include Saccharomyces cerevisiae, Aspergillus species (flavus, oryzae, niger), Saccharomycopsis fibuligera, Thermomyces lanuginosus, Rhizopus arrhizus, Issatchenkia orientalis, Wickerhamomyces anomalus, and Diutina rugosa.
