Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Theoretical Determination of Forming Limit Stress Diagram for Steel 1021 Sheet

open access: yesTikrit Journal of Engineering Sciences, 2013
Forming limit stress diagram represent the maximum acceptable limits of  principal stresses in sheet metal forming. This diagram show the limits of major and minor true stresses for different strain paths (uniaxial tension, plane strain and equibiaxial ...

Development of an in-plane biaxial test for forming limit curve (FLC) characterization of metallic sheets

open access: yes, 2010
International audienceThe main objective of this work is to propose a new experimental device able to give for a single specimen a good prediction of rheological parameters and formability under static and dynamic conditions (for intermediate strain ...

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

open access: yesFEBS 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 ...

Détermination de l'influence du trajet de déformation sur la courbe limite de formage

open access: yesVietnam Journal of Mechanics, 1996
The aim of this study is to predict the strain path influence on the forming limit diagram, from the limit stress curve. We consider two types of path, composed of two straight segments corresponding to stretching-tension and tension-stretching ...

Modeling the Near-Infrared Luminosity Functions of Young Stellar Clusters [PDF]

open access: yes, 1999
We present the results of numerical experiments designed to evaluate the usefulness of near-infrared luminosity functions for constraining the Initial Mass Function (IMF) of young stellar populations.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Prediction of forming limit diagrams using machine learning

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract Measuring forming limit diagrams (FLDs) is a time consuming and expensive process. Data-driven and artificial intelligence approaches have been used to facilitate finding relationships between alloy composition, and manufacturing processing conditions with mechanical properties of materials.

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

open access: yesFEBS 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.
