Cereb Cortex. 2021 Sep 14; doi: 10.1093/cercor/bhab295. Epub 2021 Sep 14.

Theta-gamma coupling (TGC) is a neurophysiologic mechanism that supports working memory (WM). TGC is associated with N-back performance, a WM task. Similar to TGC, theta and alpha event-related synchronization (ERS) and desynchronization (ERD) are also associated with WM. Few...

Visible-Light Removable Photocaging Groups Accepted by MjMAT Variant: Structural Basis and Compatibility with DNA and RNA Methyltransferases.

Peters A, Herrmann E, Cornelissen NV, Klöcker N, Kümmel D, Rentmeister A.
PMID: 34606675
Chembiochem. 2021 Oct 04; doi: 10.1002/cbic.202100437. Epub 2021 Oct 04.

Methylation and demethylation of DNA, RNA and proteins constitutes a major regulatory mechanism in epigenetic processes. Investigations would benefit from the ability to install photo-cleavable groups at methyltransferase target sites that block interactions with reader proteins until removed by...

People with type 2 diabetes mellitus (T2DM) are at increased risk of mild cognitive impairment and dementia. Systemic inflammation has been proposed as a common risk factor. This study aimed to summarize the clinical data pertaining to peripheral blood...

Potential impact of the COVID-19 pandemic on the national and regional incidence, epidemiology and diagnostic testing of chlamydia and gonorrhoea in Sweden, 2020.

APMIS : acta pathologica, microbiologica, et immunologica Scandinavica

APMIS. 2022 Jan;130(1):34-42. doi: 10.1111/apm.13191. Epub 2021 Nov 25.

The COVID-19 pandemic has challenged the societies and health care systems globally, and resulted in many social and physical distancing restrictions to limit the spread of SARS-CoV-2. These restrictions have also likely affected the frequency of intimate contacts and...

Two-fluid confined flow in a cylinder driven by a rotating end wall.

Physical review. E, Statistical, nonlinear, and soft matter physics

Brady PT, Herrmann M, Lopez JM.
PMID: 22400659
Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Jan;85(1):016308. doi: 10.1103/PhysRevE.85.016308. Epub 2012 Jan 12.

The flow of two immiscible fluids completely filling an enclosed cylinder and driven by the rotation of the bottom end wall is studied numerically. The simulations are in parameter regimes where there is significant advection of angular momentum, i.e.,...
