Aging is accompanied by T‐cell stiffening and reduced interstitial migration through dysfunctional nuclear organization

open access: yesImmunology, Volume 167, Issue 4, Page 622-639, December 2022., 2022
Proposed biophysical model. Abstract Age‐associated changes in T‐cell function play a central role in immunosenescence. The role of aging in the decreased T‐cell repertoire, primarily because of thymic involution, has been extensively studied. However, increasing evidence indicates that aging also modulates the mechanical properties of cells and the ...

A novel fluorescence and DNA combination for versatile, long‐term marking of mosquitoes

open access: yesMethods in Ecology and Evolution, Volume 12, Issue 6, Page 1008-1016, June 2021., 2021
Abstract Current mark–release–recapture methodologies are limited in their ability to address complex problems in vector biology, such as studying multiple groups overlapping in space and time. Additionally, limited mark retention, reduced post‐marking survival and the large effort in marking, collection and recapture all complicate effective insect ...

Intraoperative imaging for remnant viability assessment in bilateral posterior retroperitoneoscopic partial adrenalectomy in an experimental model

open access: yesBJS (British Journal of Surgery), Volume 107, Issue 13, Page 1780-1790, December 2020., 2020
Currently, the minimal functional adrenal remnant size, and the impact of intraoperative imaging technologies on remnant function after partial adrenalectomy, is unknown. In the present experimental study, intraoperative perfusion assessment, using quantitative fluorescence imaging, confocal laser endomicroscopy and contrast‐enhanced CT, enabled ...

Role of circulating fibrocytes in the diagnosis of acute appendicitis

open access: yesBJS Open, Volume 4, Issue 6, Page 1256-1265, December 2020., 2020
The circulating fibrocyte percentage is increased in patients with acute appendicitis. This may improve diagnostics, and reduce unnecessary radiation exposure and surgical operations. Circulating fibrocyte percentage may help in diagnosis of acute appendicitis. Background Improved diagnostic biomarkers are required for acute appendicitis.
