The roles of transforming growth factor-β, Wnt, Notch and hypoxia on liver progenitor cells in primary liver tumours [PDF]

open access: yes, 2014
Primary liver tumours have a high incidence and mortality. The most important forms are hepatocellular carcinoma and intrahepatic cholangiocarcinoma, both can occur together in the mixed phenotype hepatocellular-cholangiocarcinoma. Liver progenitor cells

Failure Prediction of AISI 420 Martensitic Stainless Steel Using the Theory of Critical Distances [PDF]

open access: yesMaterials Research, 2021
This work aims to evaluate the capability of the theory of critical distances (TCD) to predict the static failure of U-notched AISI 420 martensitic stainless steel specimens with different geometric features under pure bending loading.

Focal adhesion kinase: Insight into molecular roles and functions in hepatocellular carcinoma [PDF]

open access: yes, 2017
Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Due to the high incidence of post-operative recurrence after current treatments, the identification of new and more effective drugs is required.

Determination of fracture mechanics parameters on a base of local displacement measurements [PDF]

open access: yes, 2013
New experimental technique for a determination of the stress intensity factor (SIF) and T-stressvalues is developed and verified. The approach assumes combining the crack compliance method and opticalinterferometric measurements of local deformation ...

Local lung hypoxia determines epithelial fate decisions during alveolar regeneration. [PDF]

open access: yes, 2017
After influenza infection, lineage-negative epithelial progenitors (LNEPs) exhibit a binary response to reconstitute epithelial barriers: activating a Notch-dependent ΔNp63/cytokeratin 5 (Krt5) remodelling program or differentiating into alveolar type II

Morphological Variations of Distal End of Femur: A Cross-sectional Study

open access: yesInternational Journal of Anatomy Radiology and Surgery, 2022
Introduction: Apart from intercondylar notch and trochlear groove, the intercondylar line also contributes to knee joint instability. Knowledge of morphological variations of these anatomical landmarks can help in diagnosis as well as planning the ...

Strain rate concentration factor in comparison with stress concentration factor of a circumferential notch in a round bar specimen

open access: yesNihon Kikai Gakkai ronbunshu, 2017
High-speed tensile testing is now being recognized as a standard testing method for evaluating the impact strength of engineering materials. The impact speeds of Izod and Charpy tests cannot be controlled and therefore do not correspond to the real ...

An Elliptical-Shaped Dual-Band UWB Notch Antenna for Wireless Applications

open access: yesApplied Sciences, 2023
This paper discusses an elliptical ultrawideband (UWB) antenna and a dual-band UWB notch antenna. To achieve a UWB bandwidth, two corner cuts are etched into the rectangular slot on the partial ground plane.
