Microstructure Evolution and Work Hardening Behavior of Hot-Rolled DP780 Ferrite/Bainite Dual-Phase Steel

Advances in Materials Science and Engineering, 2023
In this article, by optimizing the alloy composition, the DP780 grade hot-rolled duplex steel was obtained by TMCP (thermo-mechanical control process) combined with medium temperature coiling procedure.

Umbilical Coiling Index, A Predictor of Perinatal Outcome

International Journal of Research in Pharmaceutical Sciences, 2020
Umbilical cord (UC) represents the “life source”, or the “entry and exit” point of humans which is the only source of energy. It is essential for the development, well-being, and survival of the nourishing baby. The characteristic of the coiling of the umbilical cord makes the cord a structure that is  both flexible and strong and provides resistance to

Measurement of a Broadband Negative Index with Space-Coiling Acoustic Metamaterials

Physical Review Letters, 2013
We report the experimental demonstration of broadband negative refractive index obtained in a labyrinthine acoustic metamaterial structure. Two different approaches were employed to prove the metamaterial negative index nature: one-dimensional extractions of effective parameters from reflection and transmission measurements, and two-dimensional prism ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Umbilical cord coiling index as a marker of perinatal outcome

Indian Journal of Obstetrics and Gynecology Research, 2021
The umbilical cord is very important for the well-being and survival of the fetus, however this is susceptible to compressions, kinking, traction and torsion which may influence the perinatal outcome and an abnormal umbilical coiling index has been related to adverse fetal and pregnancy outcomes.

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.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Modulation of water surface waves with a coiling-up-space metasurface

AIP Advances, 2016
We have designed a gradient-index (GRIN) metasurface to modulate water surface waves (WSWs). The metasurface is composed of an array of coiling-up-space units with a deep sub-wavelength scale, and can focus/scatter WSWs when the units are arranged ...
