A new ultrafast energy funneling material harvests three times more diffusive solar energy for GaInP photovoltaics.

Willich MM, Wegener L, Vornweg J, Hohgardt M, Nowak J, Wolter M, Jacob CR, Walla PJ.
PMID: 33318220
Proc Natl Acad Sci U S A. 2020 Dec 29;117(52):32929-32938. doi: 10.1073/pnas.2019198117. Epub 2020 Dec 14.

There is no theoretical limit in using molecular networks to harvest diffusive sun photons on large areas and funnel them onto much smaller areas of highly efficient but also precious energy-converting materials. The most effective concept reported so far...

Tissue processing and optimal visualization of cerebral infarcts following sub-acute focal ischemia in rats.

Journal of chemical neuroanatomy

Bay V, Iversen NK, Shiadeh SMJ, Tasker RA, Wegener G, Ardalan M.
PMID: 34592321
J Chem Neuroanat. 2021 Dec;118:102034. doi: 10.1016/j.jchemneu.2021.102034. Epub 2021 Sep 27.

Transient cerebral ischemia followed by reperfusion in an infarcted brain comes with predictable acute and chronic morphological alterations in neuronal and non-neuronal cells. An accurate delineation of the cerebral infarct is not a simple task due to the complex...

Faecal microbiota transplantation from patients with depression or healthy individuals into rats modulates mood-related behaviour.

Scientific reports

Knudsen JK, Michaelsen TY, Bundgaard-Nielsen C, Nielsen RE, Hjerrild S, Leutscher P, Wegener G, Sørensen S.
PMID: 34750433
Sci Rep. 2021 Nov 08;11(1):21869. doi: 10.1038/s41598-021-01248-9.

Differences in gut microbiota composition have been observed in patients with major depressive disorder (MDD) compared to healthy individuals. Here, we investigated if faecal microbiota transplantation (FMT) from patients with MDD into rats could induce a depressive-like phenotype. We...

Roton-like acoustical dispersion relations in 3D metamaterials.

Nature communications

Chen Y, Kadic M, Wegener M.
PMID: 34078904
Nat Commun. 2021 Jun 02;12(1):3278. doi: 10.1038/s41467-021-23574-2.

Roton dispersion relations have been restricted to correlated quantum systems at low temperatures, such as liquid Helium-4, thin films of Helium-3, and Bose-Einstein condensates. This unusual kind of dispersion relation provides broadband acoustical backward waves, connected to energy flow...

Short-term physical exercise impacts on the human holobiont obtained by a randomised intervention study.

BMC microbiology

Moitinho-Silva L, Wegener M, May S, Schrinner F, Akhtar A, Boysen TJ, Schaeffer E, Hansen C, Schmidt T, Rühlemann MC, Hübenthal M, Rausch P, Kondakci MT, Maetzler W, Weidinger S, Laudes M, Süß P, Schulte D, Junker R, Sommer F, Weisser B, Bang C, Franke A.
PMID: 34078289
BMC Microbiol. 2021 Jun 02;21(1):162. doi: 10.1186/s12866-021-02214-1.

BACKGROUND: Human well-being has been linked to the composition and functional capacity of the intestinal microbiota. As regular exercise is known to improve human health, it is not surprising that exercise was previously described to positively modulate the gut...

Lower beta-1,3-D-glucan testing cut-offs increase sensitivity for non-albicans Candida species blood stream infections.

Mycoses

Forster J, Dichtl K, Wagener J.
PMID: 35020235
Mycoses. 2022 Jan 12; doi: 10.1111/myc.13421. Epub 2022 Jan 12.

PURPOSE: Fungal biomarkers support early diagnosis of invasive fungal infections. In this study, we evaluated the impact of a recent update to the manufacturer-recommended cut-off for beta-1,3-D-glucan (BDG) testing (Fujifilm Wako BDG assay) on sensitivity and specificity for the...

Physical activity, well-being, and priorities of older women during the COVID-19 pandemic: a survey of Women's Health Initiative Strong and Healthy (WHISH) intervention participants.

Translational behavioral medicine

Wegner L, Mendoza-Vasconez AS, Mackey S, McGuire V, To C, White B, King AC, Stefanick ML.
PMID: 34633465
Transl Behav Med. 2021 Dec 14;11(12):2155-2163. doi: 10.1093/tbm/ibab122.

Sheltering-in-place, social distancing, and other strategies to minimize COVID-19 transmission may impact physical activity (PA) and well-being in older adults. To assess self-reported PA changes, well-being, and priorities of older women across the USA early in the COVID-19 pandemic....

Targeting 2-arachidonoylglycerol signalling in the neurobiology and treatment of depression.

Basic & clinical pharmacology & toxicology

Silveira KM, Wegener G, Joca SRL.
PMID: 33905617
Basic Clin Pharmacol Toxicol. 2021 Jul;129(1):3-14. doi: 10.1111/bcpt.13595. Epub 2021 May 17.

The endocannabinoid 2-arachidonoylglycerol (2-AG) is an atypical neurotransmitter synthesized on demand in response to a wide range of stimuli, including exposure to stress. Through the activation of cannabinoid receptors, 2-AG can interfere with excitatory and inhibitory neurotransmission in different...

On the probability of lymph node negativity in pN0-staged prostate cancer-a theoretically derived rule of thumb for adjuvant needs.

PURPOSE: The extent of lymphadenectomy and clinical features influence the risk of occult nodes in node-negative prostate cancer. We derived a simple estimation model for the negative predictive value (npv) of histopathologically node-negative prostate cancer patients (pN0) to guide...
