Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum
ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.

ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

A Unified Deep Learning Framework for Instance Segmentation Across Diverse Cytological Stains
Transformer‐based unified cytology segmentation across Papanicolaou, Feulgen and AgNOR achieves stain‐invariant performance. Mask2Former maximises boundary precision (AP75) on the combined dataset, enabling one model to replace multiple stain‐specific deployments without accuracy loss while simplifying clinical integration.

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...
