Down‐regulation of Shh in the hair follicles of mice during chemotherapy‐induced hair loss is mediated by the JAK/STAT1 signaling pathway

FEBS Open Bio, EarlyView.
We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Sustainable bioplastics manufacturing from renewable sources

FEBS Open Bio, EarlyView.
Bioplastics are manufactured by using polymers from different bio‐based sources. These novel materials not only offer biodegradability but also possess various functional properties that make them suitable for diverse applications. Recent developments in the preparation of bioplastics are reported, highlighting the distinct properties of each type of ...

3D Face Modeling Using the Multi-Deformable Method

Sensors, 2012
In this paper, we focus on the problem of the accuracy performance of 3D face modeling techniques using corresponding features in multiple views, which is quite sensitive to feature extraction errors.

3D Reassessment of the Classical Garvin's Problem

Communications in Applied and Industrial Mathematics, 2011
The exact analytical solution for surface displacements due to a volumetric linesource disturbance buried in an elastic homogeneous and isotropic half-space is arguably due to W. W. Garvin. In this work we present a generalization in the three-dimensional space of the algorithm of Garvin’s problem presented by Sanchez-Sesma and Viveros in 2006 for a ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Quasisolution of the Inverse 3D Aerohydrodynamics Problem [PDF]

Applied Mechanics and Materials, 2014
In the article we generalize the quasisolution approach to the planar aerohydrodynamics problems to 3D case. We search for solution in the form of the spline.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

3D Imaging of Dielectric Objects Buried under a Rough Surface by Using CSI

International Journal of Antennas and Propagation, 2015
A 3D scalar electromagnetic imaging of dielectric objects buried under a rough surface is presented. The problem has been treated as a 3D scalar problem for computational simplicity as a first step to the 3D vector problem.
