Chromosome movement in lysed mitotic cells is inhibited by vanadate. [PDF]

open access: yes, 1978
Mitotic PtK1 cells, lysed at anaphase into a carbowax 20 M Brij 58 solution, continue to move chromosomes toward the spindle poles and to move the spindle poles apart at 50% in vivo rates for 10 min.

Transcutaneous vagus nerve stimulation does not affect verbal memory performance in healthy volunteers [PDF]

open access: yes, 2020
Introduction: Invasive vagus nerve stimulation (VNS) improves word recognition memory in patients with epilepsy. Recent studies with transcutaneous VNS (tVNS) have also shown positive effects on various subdomains of cognitive functioning in healthy ...

Dual‐Selective Terahertz‐Nanodisc Metasurfaces for Exploring Neurotransmitter Dynamics beyond Spectral Limitations

open access: yesAdvanced Materials, EarlyView.
Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

Structure and Electrochemical Properties of ReS2‐LaFeO3 Nanocomposite for Dopamine Sensing

open access: yesAdvanced Sensor Research, EarlyView.
A novel ReS2‐LaFeO3 nanocomposite is developed for sensitive and reliable detection of dopamine (DA), an important neurotransmitter. The material performs well even in complex biological samples, demonstrating strong selectivity and accuracy. These findings highlight its potential for future applications in medical diagnostics and neuroscience research.

Norepinephrine is required to promote wakefulness and for hypocretin-induced arousal in zebrafish

open access: yeseLife, 2015
Pharmacological studies in mammals suggest that norepinephrine (NE) plays an important role in promoting arousal. However, the role of endogenous NE is unclear, with contradicting reports concerning the sleep phenotypes of mice lacking NE due to mutation

Selepressin, a novel selective vasopressin V1A agonist, is an effective substitute for norepinephrine in a phase IIa randomized, placebo-controlled trial in septic shock patients

open access: yesCritical Care, 2017
BackgroundVasopressin is widely used for vasopressor support in septic shock patients, but experimental evidence suggests that selective V1A agonists are superior.
