Faba bean (Vicia faba L.) offers a rich nutritional profile with high protein content and abundant vitamins and minerals. Processing of faba beans for freezing requires blanching, yielding liluva (legume processing water), possibly containing leached macronutrients, with potential for upcycling.

New derivatives of the -decaborate anion [BH-O(CH)O(CH)C(O)-L-OCH] (An) (: L = Trp; : L = His; : L = Met; : L = Ala(2-oxopyrrolidin-3-yl) (Pld) were synthesized and isolated as tetraphenylphosphonium salts (PhP)An. Anions ; ; , and contain a pendant functional group from the L-tryptophan methyl ester, L-histidine methyl ester, L-methionine methyl ester, or methyl 2-amino-3-(2-oxopyrrolidin-3-yl)propanoate (-Trp-OCH, -His-OCH, -Met-OCH, or -Pld-OCH) residue, respectively, bonded with the boron cluster anion through the oxybis[(ethane-2,1-diyl)oxy] spacer. This pacer is formed as a result of the nucleophilic opening of the attached dioxane molecule in the [BHO(CH)O] starting derivative.

The aim of this study was to analyze the association between circulating amino acids and central and peripheral body temperature in subjects with and without fibromyalgia syndrome (FMS). A total of 47 patients with FMS and 59 healthy subjects were included in the study. The concentration of amino acids was determined in serum samples using a fluorimeter coupled with a high-performance liquid chromatography system.

Article Synopsis
- FRET (Förster resonance energy transfer) is a technique used in gas-phase structural biology to analyze the structures of biological molecules like peptides and proteins by using donor and acceptor dyes.
- The study investigates how different amino acid (AA) methyl esters connected to a rhodamine dye affect energy transfer, employing cryogenic ion fluorescence spectroscopy for analysis.
- Results reveal that the variation in spectral outputs stems from the conformations of the dye, which are influenced by the AA side chains, and specific angles between two aromatic components that impact energy transfer efficiency.

The development of targeted therapies that correct the effect of mutations in patients with cystic fibrosis (CF) and the relevant heterogeneity of the clinical expression of the disease require biomarkers correlated to the severity of the disease useful for monitoring the therapeutic effects. We applied a targeted metabolomic approach by LC-MS/MS on saliva samples from 70 adult CF patients and 63 age/sex-matched controls to investigate alterations in metabolic pathways related to pancreatic insufficiency (PI), Pseudomonas aeruginosa (PA) colonization, CF liver disease (CFLD), and CF related diabetes (CFRD). Sixty salivary metabolites were differentially expressed, with 11 being less abundant and 49 more abundant in CF patients.
