Given two unidirectionally coupled nonlinear systems, we speak of generalized synchronization when the responder "follows" the driver. Mathematically, this situation is implemented by a map from the driver state space to the responder state space termed the synchronization map. In nonlinear times series analysis, the framework of the present work, the existence of the synchronization map amounts to the invertibility of the so-called cross map, which is a continuous map that exists in the reconstructed state spaces for typical time-delay embeddings.

RNA-directed DNA methylation (RdDM) is a plant-specific de novo methylation pathway that is responsible for maintenance of asymmetric methylation (CHH, H = A, T or G) in euchromatin. Loci with CHH methylation produce 24 nucleotide (nt) short interfering (si) RNAs. These siRNAs direct additional CHH methylation to the locus, maintaining methylation states through DNA replication.

Article Synopsis
  • The study investigates associations between benign prostatic hyperplasia (BPH) and ageing-related factors such as telomere length (TL) and mitochondrial genome copy number (mtDNA CN), focusing on tissue and blood samples from patients and a control group.
  • Findings revealed that BPH patients had longer telomeres and higher mtDNA amounts in prostate tissue compared to blood cells, while healthy controls had shorter telomeres and lower mtDNA CN.
  • No mutations were found in the gene linked to BPH, but unique mutations in mtDNA were identified, suggesting these genetic changes may influence BPH development—further research is needed to confirm these results.

Article Synopsis
  • CTCF motifs act as boundaries in chromatin domains, limiting enhancer activity and affecting gene regulation, but their disruption may only lead to mild dysregulation, making predictions about developmental impact difficult.
  • Researchers targeted a specific chromatin domain in the mouse genome with important developmental genes and found that deleting its boundary cluster caused abnormal interactions with enhancers, resulting in overexpression of FGF genes and severe developmental issues like perinatal lethality and physical malformations.
  • While some chromatin boundary changes led to significant phenotypic effects, not all CTCF clusters displayed the same sensitivity, highlighting the complexity of chromatin structure's influence on gene regulation and the need to consider small sequence variations as potential contributors to developmental and disease-related gene dysreg

Biosynthesis in bioreactors plays a vital role in many applications, but tools for accurate monitoring of the cells are still lacking. By engineering the cells such that their conditions are reported through fluorescence, it is possible to fill in the gap using fluorescence diffuse optical tomography (fDOT). However, the spatial accuracy of the reconstruction can still be limited, due to e.

A large program of research has aimed to ground large-scale cultural phenomena in processes taking place within individual minds. For example, investigating whether individual agents equipped with the right social learning strategies can enable cumulative cultural evolution given long enough time horizons. However, this approach often omits the critical processes that mediate between individual agents and multi-generational societies.

Poor maternal diet and psychosocial stress represent two environmental factors that can significantly impact maternal health during pregnancy. While various mouse models have been developed to study the relationship between maternal and offspring health and behaviour, few incorporate multiple sources of stress that mirror the complexity of human experiences. Maternal high-fat diet (HF) models in rodents are well-established, whereas use of psychosocial stress interventions in female mice are still emerging.

Introduction: Genetic predisposition to autoimmune encephalitis with antibodies against N-methyl-D-aspartate receptor (NMDAR) is poorly understood. Given the diversity of associated environmental factors (tumors, infections), we hypothesized that human leukocyte antigen () and killer-cell immunoglobulin-like receptors (), two extremely polymorphic gene complexes key to the immune system, might be relevant for the genetic predisposition to anti-NMDAR encephalitis. Notably, KIR are chiefly expressed by Natural Killer (NK) cells, recognize distinct HLA class I allotypes and play a major role in anti-tumor and anti-infection responses.

Significance: Frequency-domain diffuse optical tomography (FD-DOT) could enhance clinical breast tumor characterization. However, conventional diffuse optical tomography (DOT) image reconstruction algorithms require case-by-case expert tuning and are too computationally intensive to provide feedback during a scan. Deep learning (DL) algorithms front-load computational and tuning costs, enabling high-speed, high-fidelity FD-DOT.

Article Synopsis
  • HIV-1 integration primarily occurs in actively transcribed genes, influenced by the interaction of the viral integrase with the host chromatin factor LEDGF.
  • LEDGF is found enriched at the transcription start sites of active genes and plays a significant role in recruiting RNA Pol II, indicating its involvement in enhancing transcription.
  • The study suggests a dual role for LEDGF, where it is initially anchored to gene promoters through MLL1 and then facilitates HIV-1 integration across gene bodies, with implications for understanding specific leukemia types related to LEDGF function.

Introduction: The social determinants of health contribute to poorer health outcomes for children with cerebral palsy (CP) and are barriers to families accessing health services. At an individual level, social determinants of health are experienced as unmet social needs, for example, unsafe housing conditions. There is emerging evidence that clinical pathways for the systematic identification and referral to services for unmet social needs can support families to address these needs.
