Fluorescence spectral characteristics of DOM and its effects on the bacterial community structure in Bosten Lake, China

Journal of Freshwater Ecology
Bosten Lake is a typical inland lake in the arid and semiarid region of northwestern China. However, the influence of the dissolved organic matter (DOM) source composition on the bacterial community structure and diversity across various functional zones,

Radicalization and deradicalization: A qualitative analysis of parallels in relevant risk factors and trigger factors.

Peace and Conflict: Journal of Peace Psychology, 2020
We analysed five narrative interviews with individuals who disengaged from Islamist extremist and Salafist ideologies in an early stage of radicalization (Study 1) and seven semi-structured expert interviews with employees of German deradicalization-programmes (Study 2) to explore which root factors are common to both radicaliza-tion and ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

A novel time–frequency–space method with parallel factor theory for big data analysis in condition monitoring of complex system

International Journal of Advanced Robotic Systems, 2020
The spatial information of the signal is neglected by the conventional frequency/time decompositions such as the fast Fourier transformation, principal component analysis, and independent component analysis. Framing of the data being as a three-way array

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Factor structure of the depression anxiety stress Scale-21 (DASS-21): Unidimensionality of the Arabic version among Egyptian drug users

Substance Abuse Treatment, Prevention, and Policy, 2019
Background Emotional distress is common among illicit drug users, and it can negatively affect treatment outcomes and increase the risk of relapse. Nonetheless, instruments that properly measure emotional distress are lacking.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Passive Localization of 3D Near-Field Cyclostationary Sources Using Parallel Factor Analysis

International Journal of Antennas and Propagation, 2013
By exploiting favorable characteristics of a uniform cross-array, a passive localization algorithm of narrowband cyclostationary sources in the spherical coordinates (azimuth, elevation, and range) is proposed.
