Dual‐Responsive Dynamic Covalent Bond‐Based Assembly of Lipid‐Nanozyme Systems via Multi‐Target Synergy and Efficient Target Enrichment for Ischemic Stroke Therapy

open access: yesAdvanced Science, EarlyView.
This system adopts a biomimetic phospholipid structure, covalently binding iNOS inhibitors, neuroprotective agent PCA and vitamin E derivatives through pH/ROS dual‐responsive bonds, and assembles them with Prussian blue nanozyme to form PBB@AHA. It can efficiently penetrate the blood‐brain barrier and simultaneously release multiple active components ...

The Generation of a Testicular Peritubular Cell Line from Giant Pandas (Ailuropoda melanoleuca)

open access: yes
Giant pandas (Ailuropoda melanoleuca), a flagship endangered species under priority preservation in China, remain poorly understood in terms of their testicular physiology and the mechanisms underlying spermatogenesis. Testicular peritubular cells (TPTCs)

Coexpression of cytokeratin and vimentin in mice trophoblastic giant cells

open access: yes, 2001
Trophoblastic giant cells reach their maximum size and exhibit a conspicuous synthetic and invasive activity during mouse placentation, the cytoskeleton, given the complex functions of the cells, shows a well-developed network of intermediate filament ...

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Transfer cells and nematode induced giant cells in Helianthemum

open access: yes, 1976
The morphology of wall ingrowths in xylem and phloem transfer cells inHelianthemum is different. It is possible to use nematode infection to induce the formation of giant cells which abut both xylem and phloem elements to test whether ingrowth morphology

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

open access: yesAdvanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Cherubism and Central Giant-Cell Granuloma: A Diagnostic Predicament

open access: yesJournal of Orofacial Sciences
Cherubism and central giant cell granuloma (CGCG) present a diagnostic puzzle. Both are uncommon, benign jaw lesions harboring giant cells. Their overlapping features make them difficult to distinguish and require correlation of clinical presentation ...
