Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Strain Sensing in Cantilever Beams Using a Tapered PMF with Embedded Optical Modulation Region

Photonics
This paper presents the design of a strain-sensitive, dual ball-shaped tunable zone (DBT) taper structure for light intensity modulation. Unlike conventional tapered optical fibers, the DBT incorporates a central light field modulation zone within the ...

Texture evaluation in warm deformation of an extruded Mg–6Al–3Zn alloy

Journal of Magnesium and Alloys, 2016
To assess the effect of strain and strain rate on texture evolution of an extruded Mg–6Al–3Zn alloy, compression tests were carried out. Samples were prepared in the extrusion direction (ED) and normal direction (ND). The compression tests were performed

Transverse Load Discrimination in Long-Period Fiber Grating via Artificial Neural Network

Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2020
We present a general investigation of a Long-Period Grating (LPG) for transverse strain measurement. The transverse strain sensing characteristics, for instance, the load intensity and azimuthal angle, are analyzed with the data set generated by the LPG ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Investigating the effect of Texture Intensity on the Forming Limit Diagram of Magnesium Microtubes used in Stents using Crystal Plasticity Finite Element Modeling [PDF]

مهندسی مکانیک شریف
Metal microtubes are usually made using the extrusion method, eventually creating a special texture in the tube. The way tissue is created in the microtube has a significant effect on its mechanical properties, which is very effective in the quality of ...

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.

Light-Irradiation Wavelength and Intensity Changes Influence Aflatoxin Synthesis in Fungi

Toxins, 2018
Fungi respond to light irradiation by forming conidia and occasionally synthesizing mycotoxins. Several light wavelengths, such as blue and red, affect the latter.
