Article Abstract
A catalog of common, intermediate and well-documented (CIWD) HLA-A, -B, -C, -DRB1, -DRB3, -DRB4, -DRB5, -DQB1 and -DPB1 alleles has been compiled from over 8 million individuals using data from 20 unrelated hematopoietic stem cell volunteer donor registries. Individuals are divided into seven geographic/ancestral/ethnic groups and data are summarized for each group and for the total population. P (two-field) and G group assignments are divided into one of four frequency categories: common (≥1 in 10 000), intermediate (≥1 in 100 000), well-documented (≥5 occurrences) or not-CIWD. Overall 26% of alleles in IPD-IMGT/HLA version 3.31.0 at P group resolution fall into the three CIWD categories. The two-field catalog includes 18% (n = 545) common, 17% (n = 513) intermediate, and 65% (n = 1997) well-documented alleles. Full-field allele frequency data are provided but are limited in value by the variations in resolution used by the registries. A recommended CIWD list is based on the most frequent category in the total or any of the seven geographic/ancestral/ethnic groups. Data are also provided so users can compile a catalog specific to the population groups that they serve. Comparisons are made to three previous CWD reports representing more limited population groups. This catalog, CIWD version 3.0.0, is a step closer to the collection of global HLA frequencies and to a clearer view of HLA diversity in the human population as a whole.

Minimizing Ionic Interference: An APCI-MS Strategy for Real-Time Reaction Monitoring in Ionic Liquids.
J Mass Spectrom

Department of Chemistry and Technology of Drugs, "Sapienza" University of Rome, Rome, Italy.
Ionic liquids (ILs) are a class of organic salts with melting points below 100°C. Owing to their unique chemical and physical properties, they are used as solvents and catalysts in various chemical transformations, progressively replacing common volatile organic solvents (VOCs) in green synthetic applications. However, their intrinsic ionic nature can restrict the use of mass spectrometric techniques to monitor the time progress of a reaction occurring in an IL medium, thus preventing one from following the formation of the reaction products or intercepting the reaction intermediates.

Background: Risk stratification in posterior circulation ischemic stroke (PCIS) is challenging. Although the Posterior Circulation Ischemic Stroke Outcome Score (PCISOS) was developed to address this, its utility in minor PCIS and in identifying homogeneous populations for clinical trials or treatment-responsive subgroups remains uncertain.
Methods: CHANCE-2 (Clopidogrel in High-Risk Patients With Acute Non-disabling Cerebrovascular Events-II) was a multicenter, randomized trial that enrolled patients with minor stroke or high-risk transient ischemic attack who carried CYP2C19 loss-of-function alleles.
Synthesis of Allylic Sulfones via Generation of Metal Π-Allyl Complexes in Metal-Catalyzed Sulfonylation.

Allyl sulfones are common motifs in many drugs and natural products, exhibiting a wide range of biological activities such as anticancer and antibacterial properties, etc. An overview is provided on the synthesis of allylic sulfones via generation of metal π-allyl complexes in metal-catalyzed sulfonylation over the period from 2020 to the present. The generation process of metal π-allyl complexes is introduced from the perspective of reaction mechanism and the reaction processes such as nucleophilic substitution, insertion of SO, and reductive elimination involving metal π-allyl complexes is discussed.

Ambroxol (AMB), a common expectorant, enters aquatic environments via wastewater, yet its ecological risks remain unclear. Under UV exposure (15 mJ·cm, λ = 185-400 nm), AMB undergoes photolysis, among the photoproducts, 4-((2-amino-3-bromobenzyl)amino) cyclohexanol (P1) and 2-amino-3,5-dibromobenzaldehyde (DBA) are major species, comprising over 50% of the total photoproduct peak area at the photolytic plateau. Acute toxicity tests with AMB, P1, and DBA in four aquatic species at different trophic levels revealed: the highest sensitivity in (LC = 0.

Background: Rhabdomyosarcoma (RMS) typically responds well to a combination of treatments with favorable prognosis in children 1 to 9 years old. However, infants may fare worse due to receiving less aggressive local therapy for concerns about long-term effects of surgery/radiation. This study investigates the clinical characteristics, treatment approach, and survival outcomes of RMS in children under 2.
