Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Optogenetic methods to stimulate gamma motor neuron axons ex vivo
Abstract It is challenging to stimulate gamma motor neurons, which are important regulators of muscle spindle afferent function, without also recruiting alpha motor neurons. Here, we test the feasibility of stimulating gamma motor neuron axons using optogenetics in two transgenic mouse lines. We used an ex vivo muscle–nerve preparation in adult mice to

GbaSM-4 cells, vascular smooth muscle cells (VSMCs) derived from brain basilar arteries, were shown to migrate toward d-nicotine by augmenting the actin cytoskeleton in their cell bodies and lamellipodia, and expression of nicotinic acetylcholine ...

Abstract figure legend Schematic illustration of the bidirectional causative link between cerebral amyloid‐beta (Aβ) angiopathy and cardiovascular disease in Alzheimer's disease (AD). Common cardiovascular risk factors like microvascular thrombosis, diabetes, atrial fibrillation, hypertension and atherosclerosis lead to cerebral hypoperfusion and ...

The mysterious middlemen making your vision pop: understanding the function of amacrine cells
Abstract figure legend This review aims to illustrate the diversity and function of amacrine cells in the retina. The diversity of amacrine cell subtypes is depicted based on morphology, stratification and neurotransmitter expression, along with their synaptic connectivity with bipolar and ganglion cells, emphasizing inhibitory and modulatory roles ...

ABSTRACT Obstructive sleep apnea (OSA), characterized by repetitive upper airway obstruction, leads to chronic intermittent hypoxia (cIH) and induces cognitive and neuronal network disruptions similar to those observed in Alzheimer's disease (AD). These pathologies are often presented together in the elderly and share some pathophysiological mechanisms.

CreoPep: A Universal Deep Learning Framework for Target-Specific Peptide Design and Optimization [PDF]
Target-specific peptides, such as conotoxins, exhibit exceptional binding affinity and selectivity toward ion channels and receptors. However, their therapeutic potential remains underutilized due to the limited diversity of natural variants and the labor-intensive nature of traditional optimization strategies. Here, we present CreoPep, a deep learning-
