The Experiences of Implementing a Near-Peer Teaching Scheme Into an Undergraduate Dental Hygiene and Dental Therapy Programme at the University of Sheffield in the United Kingdom.

Objectives: To assess the learning and relationship-building potential of a near-peer teaching scheme that is low in faculty financial and time input.

Methods: This longitudinal study collects data via pre- and post-programme questionnaires completed by near-peer tutors and learners following a six-week scheme schedule. Qualitative data are analysed using a descriptive analysis model to assess the perceived value of the scheme.

Morphological Entanglement in Living Systems.

Many organisms exhibit branching morphologies that twist around each other and become entangled. Entanglement occurs when different objects interlock with each other, creating complex and often irreversible configurations. This physical phenomenon is well studied in nonliving materials, such as granular matter, polymers, and wires, where it has been shown that entanglement is highly sensitive to the geometry of the component parts.

Evolution of cell differentiation: Maintenance emerges from speedy models and simple rules.

Can simple groups of cells maintain reproductive division of labor? Or will stochastic fracturing produce groups with a single cell type? A new study uses models and experiments to show that simple biophysical traits can maintain reproductive division of labor.

Metabolically-driven flows enable exponential growth in macroscopic multicellular yeast.

The ecological and evolutionary success of multicellular lineages is due in no small part to their increased size relative to unicellular ancestors. However, large size also poses biophysical challenges, especially regarding the transport of nutrients to all cells; these constraints are typically overcome through multicellular innovations (e.g.

Impact of mastectomy flap necrosis on prepectoral reconstructive outcomes.

Introduction: As reconstructive surgeons have increasingly transitioned to the prepectoral plane for prosthetic breast reconstruction, the implications of mastectomy skin flap necrosis have become more concerning. Our goal was to evaluate the effect of skin flap necrosis on reconstructive outcomes in patients undergoing immediate prepectoral breast reconstruction.

Methods: A retrospective review was conducted of patients undergoing immediate two-stage prepectoral reconstruction at a single center with at least 3 months follow-up.
