Notch-dependent epithelial fold determines boundary formation between developmental fields in the Drosophila antenna. [PDF]

PLoS Genetics, 2017
Compartment boundary formation plays an important role in development by separating adjacent developmental fields. Drosophila imaginal discs have proven valuable for studying the mechanisms of boundary formation.

Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement

Advanced Science, EarlyView.
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

Folic acid modifies the shape of epithelial cells during morphogenesis via a Folr1 and MLCK dependent mechanism

Biology Open, 2019
Folic acid supplementation can prevent neural tube defects, but the specific molecular mechanisms by which it does have not been elucidated. During neural plate morphogenesis, epithelial cell apical constriction cooperates with other events to drive ...

Neuromorphic Devices and Computing for Sensing, Memory, and Control

Advanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Evaluation of Root Canal Morphology and Root Apex Anatomy of Mandibular Premolars in an Iranian Population: an ex-vivo study

Journal of Dental School, 2019
Objectives Adequate knowledge about canal anatomy is necessary for clinicians to prevent any damage to the periodontium. The aim of this study was to evaluate the canal and apical complexities of the mandibular first and second premolars in an Iranian ...

A Trio-RhoA-Shroom3 pathway is required for apical constriction and epithelial invagination [PDF]

Development, 2011
Epithelial invagination is a common feature of embryogenesis. An example of invagination morphogenesis occurs during development of the early eye when the lens placode forms the lens pit. This morphogenesis is accompanied by a columnar-to-conical cell shape change (apical constriction or AC) and is known to be dependent on the cytoskeletal protein ...

Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts

Advanced Science, EarlyView.
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

Advanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.

Basal constriction during midbrain–hindbrain boundary morphogenesis is mediated by Wnt5b and focal adhesion kinase

Biology Open, 2018
Basal constriction occurs at the zebrafish midbrain–hindbrain boundary constriction (MHBC) and is likely a widespread morphogenetic mechanism. 3D reconstruction demonstrates that MHBC cells are wedge-shaped, and initially constrict basally, with ...

Nuclear IDH3A Drives Transcriptional Programs in Melanoma via the YBX1–JUN/FOS Axis

Advanced Science, EarlyView.
Genomic amplification drives aberrant nuclear localization of IDH3A in melanoma. Independent of its canonical metabolic activity, nuclear IDH3A cooperates with YBX1 to activate the c‐JUN/c‐FOS transcriptional program, while NONO facilitates its nuclear localization.
