The frequency of first-trimester vaginal bleeding among 670 women with chromosomally normal fetal losses and 219 women with chromosomally abnormal losses was compared with that among 3089 women delivered at term. Vaginal bleeding early in gestation was predictive of pregnancy outcome in that moderate or heavy bleeding was associated with a fourfold risk of the loss of either chromosomally normal or abnormal conceptions. Spotting or slight bleeding was associated with a 2.7-fold risk of the loss of a chromosomally normal conception but was not associated with the loss of chromosomally abnormal conceptions when all abnormalities were categorized together.

Karyotype instability in the germline leads to infertility. Unlike the female germline, the male germline continuously produces fertile sperm throughout life. Here we present a molecular network responsible for maintaining karyotype stability in the male mouse germline.

Richter syndrome (RS), characterized by aggressive lymphoma arising from chronic lymphocytic leukaemia (CLL), presents a poor response to treatment and grim prognosis. To elucidate RS mechanisms, paired samples from a patient with DLBCL-RS were subjected to single-cell RNA sequencing (scRNA-seq) and high-throughput chromosome conformation capture (Hi-C) sequencing. Over 10,000 cells were profiled via scRNA-seq, revealing the comprehensive B cell transformation in RS.

Creation and long-term in vitro maintenance of valuable genotype collection is one of the modern approach to conservation of valuable gene pool of woody plants. However, during prolonged cultivation, genetic variability of cells and tissues may accumulate and lead to the loss of valuable characteristics of parental plants. It is therefore important to assess the genetic (including cytogenetic) stability of collection clones.

The black bream () is an economically important species widely distributed in China, with its geographic populations potentially having undergone differentiations and local adaptations. In this study, we presented a chromosome-level genome assembly of this species and investigated genetic differentiations of its populations that are allopatric (the northern one) and sympatric (the Poyang Lake) to its kin species, the blunt-snout bream (), using whole genome resequencing analysis. The results showed that the genome size of black bream was 1.
