Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations
FEBS Open Bio, EarlyView.We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...

Mapping Hsp104 interactions using cross‐linking mass spectrometry
FEBS Open Bio, EarlyView.This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

Clinical utility of cerebrospinal fluid biomarkers measured by LUMIPULSE® system
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1898-1909, December 2022., 2022 Abstract Objectives Cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) are well‐established in research settings, but their use in routine clinical practice remains a largely unexploited potential. Here, we examined the relationship between CSF biomarkers, measured by a fully automated immunoassay platform, and brain β‐amyloid (Aβ ...

Neretin groups admit no non-trivial invariant random subgroups [PDF]
arXiv, 2019 We show that Neretin groups have no non-trivial invariant random subgroups. These groups provide first examples of non-discrete, compactly generated, locally compact groups with this property.

Hydrogen sulfide repairs testicular damage induced by heat stress in rats
FEBS Open Bio, EarlyView.Heat stress can cause testicular damage and affect fertility. We investigated the potential protective role of hydrogen sulfide (H2S) against heat stress‐induced testicular injury and observed that H2S donor NaHS can effectively restore testicular damage in rats by inhibiting inflammation and oxidative stress. Our results suggest that H2S might be used

Vascular endothelial‐cadherin as a marker of endothelial injury in preclinical Alzheimer disease
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1926-1940, December 2022., 2022 Abstract Objective Endothelial dysfunction is an early and prevalent pathology in Alzheimer disease (AD). We here investigate the value of vascular endothelial‐cadherin (VEC) as a cerebrospinal fluid (CSF) marker of endothelial injury in preclinical AD.

Local cyclic homology of group Banach algebras I: Hyperbolic groups [PDF]
arXiv, 2016 We calculate the bivariant local cyclic cohomology of the Banach convolution algebra of summable functions on a word-hyperbolic group. Our result implies that the Banach algebraic assembly map in local cyclic homology is an isomorphism for such a group.
