Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Proposal for Hemiplegic Thumb Rehabilitation Device Based on Repetitive Facilitation Exercise

Machines
In this paper, we propose a thumb rehabilitation device based on the concept of Repetitive Facilitation Exercise (RFE) therapy. Our device only uses rapid passive stretching to the extensor muscle to induce a stretch reflex as a facilitative stimulation.

Modeling and Identification of Mechanical and Reflex Properties related to Spasticity in Stroke Patients using Multiple Pendulum Tests

Journal of Biomechanical Science and Engineering, 2011
We propose a method for the comprehensive identification of spastic and intrinsic properties of spastic knee joints using multiple pendulum tests. The stretch reflex system was modeled as a velocity feedback loop where the key component was the muscle ...

Tongue reflex for speech posture control

Scientific Reports
Although there is no doubt from an empirical viewpoint that reflex mechanisms can contribute to tongue motor control in humans, there is limited neurophysiological evidence to support this idea.
