Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

open access: yesAdvanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Associations Between Parent-Child Relationship Quality, Parent Feeding Practices, and Child Weight Status in Preadolescent Children

open access: yes, 2017
The present study evaluated associations between parent-child connectedness and communication, parent perceptions of child weight, parent feeding behaviors (restriction, pressure to eat, and monitoring), and child body mass index percentile among a ...

Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

open access: yesAdvanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

Introducing the child and its parent(s): Child-teacher-parent relationship-building during preschool transition [PDF]

open access: yes
Current child developmental research encourages a more systemic understanding of attachment-related relationship-building. As many young children spend a substantial part of their daily life in professional childcare, e.g., “preschool”, interactions with

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

open access: yesAdvanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

NICE: A Two‐Step Non‐Invasive Framework for Embryo cfDNA Read Enrichment and Quality Assessment

open access: yesAdvanced Science, EarlyView.
The non‐invasive NICE framework, built on an ensemble stacking machine learning model, prioritizes embryos by analyzing cell‐free DNA from spent culture medium. By integrating multimodal signals, including genomic and epigenetic profiles, this automated approach standardizes morphological assessment without human bias, paving the way for more precise ...

The Influence of Parent-Child Playtime on the Parent-Child Relationship Among Malaysian Families

open access: yes
Behavioral problems including mental health issues among young children have become increasingly alarming in recent years. According to the data, a poor parent-child relationship has been a significant contributing factor to its prevalence.
