Genes and Mechanisms Involved in the Generation and Amplification of Basal Radial Glial Cells

Frontiers in Cellular Neuroscience, 2019
The development of the cerebral cortex relies on different types of progenitor cell. Among them, the recently described basal radial glial cell (bRG) is suggested to be of critical importance for the development of the brain in gyrencephalic species ...

Molecular Crowding and Diffusion-Capture in Synapses

iScience, 2020
Summary: Cell membranes often contain domains with important physiological functions. A typical example are neuronal synapses, whose capacity to capture receptors for neurotransmitters is central to neuronal functions.

Consequences of Medium‐Pore Zeolite Constraints for Alkene Cracking—The Case of n‐Pentene

Angewandte Chemie, EarlyView.
Alkene cracking in medium‐pore zeolites is governed by a balance of enthalpic and entropic effects. Intrinsic barriers are quantified and shown to be lower than for alkanes due to stabilization of carbenium‐ion‐like transition states. Confinement and extra‐framework aluminum modulate reactivity by tuning transition‐state energetics, providing a ...

What is the degree of segregation between striatonigral and striatopallidal projections?

Frontiers in Neuroanatomy, 2010
In contrast to most other brain regions, in the striatum the output neurons (the medium-sized spiny neurons, MSNs) are GABAergic and act by inhibiting their targets.

NKCC1 and KCC2 Chloride Transporters Have Different Membrane Dynamics on the Surface of Hippocampal Neurons

Cells, 2023
Na-K-2Cl cotransporter 1 (NKCC1) regulates chloride influx in neurons and thereby GABAA receptor activity in normal and pathological conditions. Here, we characterized in hippocampal neurons the membrane expression, distribution and dynamics of exogenous

Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

Advanced Materials Technologies, EarlyView.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

Implications of Flavor Dynamics for Fermion Triplet Leptogenesis [PDF]

, 2010
We analyze the importance of flavor effects in models in which leptogenesis proceeds via the decay of Majorana electroweak triplets. We find that depending on the relative strengths of gauge and Yukawa reactions the $B-L$ asymmetry can be sizably ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,
