Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

open access: yesAdvanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Unraveling the role of cAMP signaling in Giardia: insights into PKA-mediated regulation of encystation and subcellular interactions

open access: yesmSphere
cAMP plays an important role as a second messenger in the stage transition of various protozoan parasites. This signaling pathway relies on multiple effectors, such as protein kinase A (PKA), exchange protein activated by cAMP, and cAMP-response element ...

Fabrication of a Stable, Low‐Cost, Patient‐Specific, Brain Phantom with Ventricles for Ultrasound Imaging

open access: yesAdvanced Engineering Materials, EarlyView.
Patient‐specific brain phantoms can replace animal trials, aid presurgical training, and enable in silico disease research on cerebrospinal fluid and ventricles. This study presents a method to create ventricular brain phantoms from three‐dimensional magnetic resonance images brain scans, resulting in durable, tunable, reproducible models that mimic ...

Cyclic AMP modulation of ion transport across frog retinal pigment epithelium. Measurements in the short-circuit state. [PDF]

open access: yes, 1984
In the frog retinal pigment epithelium (RPE), the cellular levels of cyclic AMP (cAMP) were measured in control conditions and after treatment with substances that are known to inhibit phosphodiesterase (PDE) activity (isobutyl-1-methylxanthine, SQ65442)
