Type II topoisomerases shape multi-scale 3D chromatin folding in regions of positive supercoils.

Type II topoisomerases (TOP2s) resolve torsional stress accumulated during various cellular processes and are enriched at chromatin loop anchors and topologically associated domain (TAD) boundaries, where, when trapped, can lead to genomic instability promoting the formation of oncogenic fusions. Whether TOP2s relieve topological constraints at these positions and/or participate in 3D chromosome folding remains unclear. Here, we combine 3D genomics, imaging, and GapRUN, a method for the genome-wide profiling of positive supercoiling, to assess the role of TOP2s in shaping chromosome organization in human cells.

Cross-National Comparisons of Internalizing Problems in a Cohort of 8952 Adolescents from Five European Countries: The EU NET ADB Survey.

Various factors such as family relationships, socioeconomic indicators, socio-cultural aspects, mental health problems and demographic variables, have been associated with internalizing problems in adolescence. The purpose of this study was to examine the prevalence of internalizing problems in adolescents from five European countries in comparison with risk factors. Using data from the European Network for Adolescent Behavior (EU NET ADB) survey, a cross-sectional school-based study of adolescents (from 14 to 17.

Psycho-emotional consequences in pregnant women during the COVID-19 pandemic.

Fear of COVID-19, especially in vulnerable groups such as pregnant women, created excessive concern leading to unexpected psycho-emotional consequences and a need to summarize the most recent knowledge about this topic. Therefore, we conducted a narrative review of the relevant literature, synthesizing data from available databases.

The impact of COVID-19 during pregnancy on maternal and neonatal outcomes: a systematic review.

Several months after the onset of the epidemic, COVID-19 remains a global health issue. Scientific data on pregnancy, perinatal outcomes and vertical transmission of SARS-CoV-2 are constantly emerging but are still limited and unclear. The purpose of this systematic review was to summarize current evidence on vertical transmission rates, maternal, perinatal and neonatal outcomes and mode of delivery in pregnancies affected by COVID-19.

Distinguishing activated T regulatory cell and T conventional cells by single-cell technologies.

Resting conventional T cells (Tconv) can be distinguished from T regulatory cells (Treg) by the canonical markers FOXP3, CD25 and CD127. However, the expression of these proteins alters after T-cell activation leading to overlap between Tconv and Treg. The objective of this study was to distinguish resting and antigen-responsive T effector (Tconv) and Treg using single-cell technologies.
