Advanced Science, EarlyView.Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the

Fuel-Powered Artificial Muscles
Science, 2006 Artificial muscles and electric motors found in autonomous robots and prosthetic limbs are typically battery-powered, which severely restricts the duration of their performance and can necessitate long inactivity during battery recharge. To help solve these problems, we demonstrated two types of artificial muscles that convert the chemical energy of ...

Pressurized artificial muscles
Journal of Intelligent Material Systems and Structures, 2011 Pressurized artificial muscles are reviewed. These actuators consist of stiff reinforcing fibers surrounding an elastomeric bladder and operate using a pressurized internal fluid. The pressurized artificial muscles, known as McKibben actuators or flexible matrix composite actuators, can be applied to a wide array of applications, including prosthetics ...

Transversal Pneumatic Artificial Muscles
2015 10th International Workshop on Robot Motion and Control (RoMoCo), 2015The paper presents an innovative construction of Pneumatic Artificial Muscles. Due to transverse deformation of the muscle, it allows obtaining a linear displacement by changing a diameter of a muscle. The new type of drive, which is represented by this solution, can be used in a robot designed for exploration of a human intestine.

Axial vibration of an artificial muscle
2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE), 2015Significant number of muscles can be assumed to be of longitudinal type where the length is much higher than its cross-section. Usual motion of the longitudinal muscles is axial due to its contraction and dilatation. Our aim is to investigate the axial vibration of such muscles.
