In the crystal structure of the title compound, C(6)H(10)N(3) (+)·C(7)H(2)I(3)O(2) (-)·C(7)H(3)I(3)O(2), two R(2) (2)(8) motifs are observed. One is generated by the inter-action of the 2-amino-4,6-dimethyl-pyrimidin-1-ium cation with the carboxyl-ate group of the 2,3,5-triiodo-benzoate anion via N-H⋯O hydrogen bonds. The other R(2) (2)(8) motif is formed by the inter-action of two centrosymmentrically related pyrimidine moieties through N-H⋯N hydrogen bonds. The two motifs combine to form a linear heterotetra-meric unit. Heterotetra-meric units are linked by a carbox-yl-carboxyl-ate O-H⋯O hydrogen bond (involving the O-H group of neutral 2,3,5-triiodo-benzoic acid and an O atom of the anion), forming a supra-molecular chain along the a axis. In addition, components are held by weak I⋯O interactions in the range 3.023 (5) to 3.382 (5) Å and I⋯I inter-actions in the range 3.6327 (7) to 4.0025 (8) Å.

The identification of neoantigens is crucial for advancing vaccines, diagnostics, and immunotherapies. Despite this importance, a fundamental question remains: how to model the presentation of neoantigens by major histocompatibility complex class I molecules and the recognition of the peptide-MHC-I (pMHC-I) complex by T cell receptors (TCRs). Accurate prediction of pMHC-I binding and TCR recognition remains a significant computational challenge in immunology due to intricate binding motifs and the long-tail distribution of known binding pairs in public databases.

Cuproptosis exhibits enormous application prospects in treatment. However, cuproptosis-based therapy is impeded by the limited intracellular copper ions, the nonspecific delivery, uncontrollable release, and chelation of endogenous overproduced glutathione (GSH). In this work, an ultrasound-triggered nanosonosensitizer (p-TiO-Cu(I)) was constructed for Cu(I) delivery, on-demand release, GSH consumption, and deeper tissue response.

Infertility poses a global challenge that impacts a significant proportion of the populace. Presently, there is a substantial emphasis on investigating the potential of probiotics and their derivatives, called postbiotics, as an alternative therapeutic strategy for addressing infertility. The term of "postbiotics" refers to compounds including peptides, enzymes, teichoic acids, and muropeptides derived from peptidoglycans, polysaccharides, proteins, and organic acids that are excreted by living bacteria or released after bacterial lysis.

Bile acids, synthesized in the liver and modified by the gut microbiota, play vital roles in various physiological processes. The dysregulation of bile acids has been extensively documented in patients with neurodegenerative diseases. However, limited attention has been given to the protein targets associated with microbiota-derived bile acids in neurological diseases.

This study investigates the production of high-purity cellulose pulp from peach (Prunus persica) fruit wastes generated during the processing of a Greek compote and juice production industry. A three-step chemical process is used, including alkaline treatment with NaOH, organic acid (acetic and formic) treatment, and hydrogen peroxide treatment, with the goal of cellulose extraction and purification. A fractional factorial design optimized reagent levels, revealing the strong influence of NaOH concentration on α-cellulose content and degree of polymerization.
