Active modeling for pneumatic artificial muscle
, 2016 In this paper, an active modeling approach for a pneumatic artificial muscle (PAM) is being considered. The PAM's nonlinearity, hysteresis and time-varying characteristics cause difficulties in modeling its behavior and designing high-performance ...

Shape-Memory Polymeric Artificial Muscles: Mechanisms, Applications and Challenges
Molecules, 2020 Shape-memory materials are smart materials that can remember an original shape and return to their unique state from a deformed secondary shape in the presence of an appropriate stimulus.

Molecular Oncology, EarlyView.A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Mixed phase activated artificial muscle
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 This article presents the mixed phase as the pressure medium of hydraulic artificial muscles, which has rarely been mentioned before. Then a novel mixed phase activated artificial muscle is designed.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Characterization and Analysis of Extensile Fluidic Artificial Muscles
Actuators, 2021 Extensile fluidic artificial muscles (EFAMs) are soft actuators known for their large ranges of extension, low weight, and blocked forces comparable to those of pneumatic cylinders.

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Artificial neural network inference analysis identified novel genes and gene interactions associated with skeletal muscle aging [PDF]
Background: Sarcopenia is an age-related muscle disease that increases the risk of falls, disabilities, and death. It is associated with increased muscle protein degradation driven by molecular signalling pathways including Akt and FOXO1. This study aims
