Spindle apparatus uncoupling in endo-tetraploid asymmetric division of stem and non-stem cells

open access: yesCell Cycle, 2009
3234 Cell Cycle Volume 8 issue 19 cause is indicated in a three-dimensional study in which BrdU labeling (new DNA) of the structurally complex, heterochromatic centromere area occurred “at the periphery of the domain”. In Figure 1 the copying restriction

Monolithic Desktop Digital Fabrication of Autonomous Walking Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft, monolithic, air‐powered walking robot is designed for autonomous operation. Fabricated in a single step using a desktop (FFF) fused filament fabrication 3D printer, the robot requires no manual postassembly and becomes immediately operational with a constant‐pressure air supply.

Superhydrophobic Solution Blow Spinning PTFE–SiO2 Composite Membranes for Enhanced Liquid–Liquid Extraction

open access: yesJournal of Applied Polymer Science, EarlyView.
Solution blow spinning PTFE‐SiO2 membrane for membrane assisted solvent extraction. ABSTRACT An ultrafine‐fibrous polytetrafluoroethylene (PTFE)–SiO2 membrane was successfully fabricated using the solution blow spinning (SBS) method. This membrane demonstrated superhydrophobicity (water contact angle > 150°) and oleophilicity (ethyl acetate contact ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Dynamic Plasma Membrane Topography Linked With Arp2/3 Actin Network Induction During Cell Shape Change

open access: yesBioEssays, EarlyView.
Cell shape changes underlie animal development, physiology, and disease. The cell surface is mechanosensitive to the microenvironment and cytoskeleton activities, which generate plasma membrane topographies recognized and affected by Arp2/3 actin network induction pathways to remodel cell shape during immune cell migration, neural progenitor cell ...

Neural electrodes for brain‐computer interface system: From rigid to soft

open access: yesBMEMat, EarlyView.
Here, we review the development trends of neural electrodes in BCI. This paper highlights the critical role of electrodes in BCI systems, analyzes the limitations of rigid electrodes, and introduces various flexible electrodes. Furthermore, we discuss application scenarios and prospects of BCI electrode technology, aiming to provide valuable references

Role of Glutamate Excitotoxicity in Glioblastoma Growth and Its Implications in Treatment

open access: yesCell Biology International, EarlyView.
ABSTRACT Glioblastoma is a highly malignant and invasive type of primary brain tumor that originates from astrocytes. Glutamate, a neurotransmitter in the brain plays a crucial role in excitotoxic cell death. Excessive glutamate triggers a pathological process known as glutamate excitotoxicity, leading to neuronal damage.

A two‐dimensional morphospace for cyanobacteria and microalgae: Morphological diversity, evolutionary relatedness, and size constraints

open access: yesFreshwater Biology, Volume 68, Issue 1, Page 115-126, January 2023., 2023
Abstract Body metrics are considered as master traits that regulate physiological, behavioural and life history features of planktic cyanobacteria and microalgae. Although the distribution of their morphological traits reflects the various trade‐offs and strategies needed for survival in pelagic habitats, previous methods for quantifying phytoplankton ...
