Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Monitoring the New Circular Pedestrian Steel Bridge over the São Roque and Botirões Channels with Weldable Fiber-Bragg Grating Sensors

, 2006
To monitor a new circular pedestrian bridge, new strain and temperature sensors based on fiber Bragg gratings were developed to be directly welded to the steel structure, as well as proper protection and installation ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Fiber Optic Sensor Configurations

Proceedings of the 3rd International Conference on Photonics, Optics and Laser Technology, 2015
The main goal of this work is to provide a brief overview of the fiber optic sensor multiplexing configurations and techniques as well as some recent advances and trends of the most important fiber optic sensor configurations. Distributed and point sensors are explained and a number of high performance networks are shown. Finally, the concept of robust

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Fibre grating refractometer sensors for composite process monitoring [PDF]

, 2007
Optimum performance from advanced composites requires careful control of the resin matrix during cure. This is to ensure there are no cure induced voids and to minimise the build up of internal stresses.
