Allergy

December 2024

Institute and Clinic for Occupational, Social and Environmental Medicine, LMU University Hospital, LMU Munich, Munich, Germany.

Background: Using disinfectants and cleaning products (DCPs) at home and work is known to influence both the onset and course of asthma, but most epidemiological studies did not consider the multiplicity and correlations of exposures to DCPs. We aimed to identify exposure profiles for the long-term weekly use of DCPs by latent class analysis (LCA) and assess their associations with asthma.

Methods: LCA was conducted on data from 1143 young adults initially recruited in the German centers of Phase II of the International Study of Asthma and Allergies in Childhood (ISAAC) and followed up three times.

Pre-emptive kidney transplantation (PKT) has long been considered the optimal treatment for patients with end-stage chronic kidney disease (CKD) seeking the most favourable long-term outcomes. However, the significant growth in transplant procedures over recent decades has led to a notable increase in wait-listed patients and a disproportionate demand for donor organs. This situation necessitates a re-evaluation of transplantation timing and the establishment of rational indications from both societal and clinical perspectives.

During meiosis, programmed DNA double-strand breaks (DSBs) are formed by the topoisomerase-like enzyme, Spo11, activating the DNA damage response (DDR) kinase Mec1ATR via the checkpoint clamp loader, Rad24RAD17. At single loci, loss of Mec1 and Rad24 activity alters DSB formation and recombination outcome, but their genome-wide roles have not been examined in detail. Here, we utilise two strategies-deletion of the mismatch repair protein, Msh2, and control of meiotic prophase length via regulation of the Ndt80 transcription factor-to help characterise the roles Mec1 and Rad24 play in meiotic recombination by enabling genome-wide mapping of meiotic progeny.
