Engineering Extracellular Vesicle Production Through Magnetic Ion Channel Activation for Bone Regeneration

Advanced Healthcare Materials, EarlyView.
Magnetic Ion Channel Activation (MICA) enables remote stimulation of mechanosensitive ion channels using functionalised magnetic nanoparticles, enhancing extracellular vesicle (EV) biogenesis is pre‐osteoblasts. MICA desrived EVs exhibit typical nano‐vesicular characteristics but display superior pro‐osteogeneic activity, promoting mesenchymal stem ...

ON THE OSCILLATION OF A THIRD ORDER NONLINEAR DIFFERENTIAL EQUATIONS WITH NEUTRAL TYPE

Ural Mathematical Journal, 2017
In this article, we investigate that oscillation behavior of the solutions of the third-order nonlinear differential equation with neural type of the form $$ \Big(a_{1}(t)\big(a_{2}(t)Z^{\prime}(t)\big)^{\prime}\Big)^{\prime} + q(t) f\big(x(\sigma(t ...

The multidimensional relationship between alpha oscillations and cognition

Imaging Neuroscience
Abstract Alpha oscillations are a robust neurophysiological phenomenon associated with cortical suppression and synaptic input gating, functionally interpreted as a mechanism of selective attention. Here, we highlight known dissociations between alpha oscillations and selective attention that question the specificity of this ...

Three‐Dimensional Ovary Model to Improve and Study Murine Follicle Growth

Advanced Healthcare Materials, EarlyView.
To develop new methods for fertility preservation in women, novel culture systems for small follicles need to be established. In this work, a poly(ethylene glycol) based scaffold, with appropriate mechanical and bioactive features to support mouse follicle and ovary cell growth is developed, and the formed cell‐follicle interactions are visualized ...

Abnormal resting-state EEG neural oscillations and functional connectivity in mild cognitive impairment

Frontiers in Aging Neuroscience
BackgroundMild cognitive impairment (MCI) exhibits abnormal resting-state EEG oscillations in delta (1–4 Hz), theta (4–7 Hz), and alpha (8–13 Hz) bands, though findings remain inconsistent.

Oscillation theorems for nonlinear differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2000
We establish new oscillation theorems for the nonlinear differential equation $$[a(t)\psi(x(t))|x'(t)|^{\alpha-1}x'(t)]'+q(t)f(x(t))=0, \alpha>0$$ where $a,q:[t0,\infty)\rightarrow R, \psi,f:R\rightarrow R$ are continuous, $a(t)>0$ and $\psi(x)>0$, $xf(x)

Modulation of alpha oscillations is required for the suppression of semantic interference

Neurobiology of Learning and Memory, 2017
Recent findings on alpha band oscillations suggest their important role in memory consolidation and suppression of external distractors such as environmental noise. However, less attention was given to the phenomenon of internal distracting information being solely inherent to the stimuli content.
