Membrane‐Mediated Force Transduction Drives Stick‐Slip Motion of Lipid Vesicles

Advanced Science, EarlyView.
A rotating magnetic field actuates a ferromagnetic particle inside a lipid vesicle, generating internal flows that induce stick‐slip propulsion near a surface. Membrane properties—elasticity, excess area, and phase behavior—modulate this motion by shaping stress dissipation and force transduction.

Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance

Advanced Science, EarlyView.
DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

Resilience to Endoplasmic Reticulum Stress Mitigates Membrane Hyperexcitability Underlying Late Disease Onset in a Murine Model of SCA6

Annals of Neurology, EarlyView.
Objective An enduring puzzle in many inherited neurological disorders is the late onset of symptoms despite expression of function‐impairing mutant protein early in life. We examined the basis for onset of impairment in spinocerebellar ataxia type 6 (SCA6), a canonical late‐onset neurodegenerative ataxia which results from a polyglutamine expansion in ...

Depolarization increases cellular light transmission [PDF]

, 2008
Application of optical methods to human brain tissue in vivo, e.g., measuring oxyhemoglobin and deoxyhemoglobin concentration changes with near-infrared spectroscopy (NIRS), requires the a priori assumption that background optical properties remain ...

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

Biotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.
