Elevated Peripheral CD161+ Treg Cells and Their Clinical Significance in Behçet Syndrome

ACR Open Rheumatology, Volume 8, Issue 3, March 2026.
Objective Behçet syndrome (BS) is a systemic autoimmune vasculitis characterized by immune dysregulation involving multiple immune cell subsets. CD161+ Treg cells exhibit proinflammatory properties and impair immune regulation during inflammation. This study aimed to investigate the alterations in CD161+ Treg cells in BS and their clinical relevance ...

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Algorithm for Automatic Peak Detection and Quantification for GC-IMS Spectra

, 2020
Ion Mobility Spectrometry with a coupled Gas Chromatography (GC-IMS) pre-separation is an analytical technique suitable for detection of volatile organic compounds (VOCs) in complex sample matrices (indoor & outdoor air, breath samples, food, beverages, microbial cultures, etc.). Its outstanding sensitivity allows in-situ analysis of a very large range

Predation Risk Does Not Delay Breeding but Reduces Nest Survival in High‐Arctic Shorebirds

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We assessed the impact of arctic foxes' predation pressure on two sympatric sandpiper species. Fox activity influenced the breeding ecology of both sandpipers, with earlier nest initiations and lower nest survival rates in areas of high fox activity. ABSTRACT Understanding predator–prey interactions is crucial for correctly answering many fundamental ...

Computational methods for metabolomic data analysis of ion mobility spectrometry data-reviewing the state of the art [PDF]

, 2012
Ion mobility spectrometry combined with multi-capillary columns (MCC/IMS) is a well known technology for detecting volatile organic compounds (VOCs). We may utilize MCC/IMS for scanning human exhaled air, bacterial colonies or cell lines, for example ...

Diagnosis of COVID-19 by analysis of breath with gas chromatography-ion mobility spectrometry - a feasibility study [PDF]

, 2020
Background There is an urgent need to rapidly distinguish COVID-19 from other respiratory conditions, including influenza, at first-presentation. Point-of-care tests not requiring laboratory- support will speed diagnosis and protect health-care staff. We

Ginseng Volatile Oil Alleviates Loperamide‐Induced Constipation in Mice by Regulating the Microbiota/Metabolism/Neural Network

Food Frontiers, Volume 7, Issue 2, March 2026.
GVO relieves constipation mechanisms. GVO decreased the abundance of Firmicutes and increased that of Bacteroidota, thereby ameliorating Lop‐induced gut microbial imbalances. Then the level of 8,9‐DiHETrE was raised, whereas the level of 15(S)‐HpETE was lowered.
