Persistent activation of the zeta isoform of protein kinase C in the maintenance of long-term potentiation

TL;DR: The transition from translocation of PKC to formation of PKM may help to explain the molecular mechanisms of induction and maintenance of long-term potentiation.
Journal ArticleDOI

Evidence for a new, high-molecular weight isoform of protein kinase C in rat hippocampus

TL;DR: A new form of protein kinase C (PKC) is described with a molecular weight of 97 kDa, higher than the known forms of vertebrate PKC, and is localized primarily in brain, in contrast to PKC eta, which is found predominantly in lung and skin.

SARS-CoV-2 Slows Brain Rhythms with more Severe Effects in Younger Individuals

TL;DR: Quantitative analysis of EEG showed distinct slowing of brain rhythms in C19 patients compared to control, and machine learning algorithms showed consistently higher accuracy in the binary classification of patients as C19 versus control using EEG power for subjects below age 70 compared to older ones, providing further evidence for the more severe impact of SARS-CoV-2 on brain rhythm in younger individuals.
Journal ArticleDOI

SARS-CoV-2 alters neural synchronies in the brain with more severe effects in younger individuals

TL;DR: In this article , the authors developed a computational pipeline for the automated, rapid, high-throughput and objective analysis of electroencephalography (EEG) rhythms, and used this pipeline to define the quantitative EEG changes in patients with a PCR-positive diagnosis of CoV-2 (COVID19 or C19) in the intensive care unit (ICU) of Cleveland Clinic, compared to a group of age-matched PCR-negative (n = 38) control patients in the same ICU setting.
