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.

On the Capacity and Performance of Generalized Spatial Modulation
, 2015 Generalized spatial modulation (GSM) uses $N$ antenna elements but fewer radio frequency (RF) chains ($R$) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with $R=1$ and $R=N$, respectively.

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.

Low complexity detection algorithm applied to spatial modulation system
Dianzi Jishu Yingyong, 2019 The paper proposes a low-complexity detection algorithm for spatial modulation. The proposed algorithm reduces the total complexity by reordering the receiving antennas. The algorithm combines the existing A-Star algorithm to layer and sort the receiving

Law for the distance between successive earthquakes
, 2003 Discovery of a new law for three dimensional spatial distance between the foci of successive earthquakes is reported. Analyzing the seismic data taken between 1984 and 2001 in southern California, it is found that the cumulative distribution of the ...

COG complexes form spatial landmarks for distinct SNARE complexes [PDF]
Nature Communications, 2013 Vesicular tethers and SNAREs (soluble N-ethylmalemide-sensitive fusion attachment protein receptors) are two key protein components of the intracellular membrane-trafficking machinery. The conserved oligomeric Golgi (COG) complex has been implicated in the tethering of retrograde intra-Golgi vesicles.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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

Hume and the Perception of Spatial Magnitude [PDF]
, 2004 This paper investigates Hume's theory of the perception of spatial magnitude or size as developed in the _Treatise\u3cD\u3e, as well as its relation to his concepts of space and geometry.

Gutzwiller Monte Carlo approach for a critical dissipative spin model
, 2017 We use the Gutzwiller Monte Carlo approach to simulate the dissipative XYZ-model in the vicinity of a dissipative phase transition. This approach captures classical spatial correlations together with the full on-site quantum behavior, while neglecting ...
