Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Heat Exchange and Flow Resistance in a Heat Exchanger Based on a Minimal Surface of the Gyroid Type—Results of Experimental Studies

Energies
The gyroid minimal surface is one type of triply periodic minimal surface (TPMS). TPMS is a minimal surface replicated in the three main directions of the Cartesian coordinate system.

Microfluidic electro‐viscoelastic manipulation of extracellular vesicles

FEBS Open Bio, EarlyView.
The electro‐viscoelastic manipulation as a potential method for separation of particles based on size. The particles introduced as a sheath flow migrate to the channel center under the influence of simultaneously applied electric field and pressure driven flow.

Classification of weak del Pezzo pairs for surfaces

Mathematics Open
A weak del Pezzo surface is a smooth projective surface whose anticanonical divisor [Formula: see text] is nef and big. We generalize this concept to weak del Pezzo pairs for surfaces and classify those with minimal and non-minimal properties.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Validation of material-invariant mechanical models for triply periodic minimal surface structures

Results in Materials
Their dual functionality makes triply periodic minimal surface (TPMS) sheet networks an ideal candidate for permeable, load-bearing cellular structures. The present study investigates Gyroid and Primitive structures in quasi-static compression.

Lactoferrin treatment activates acetylcholinesterase, decreasing acetylcholine levels in non‐small cell lung cancer (NSCLC) cell culture supernatants, inhibiting cell survival

FEBS Open Bio, EarlyView.
Representation of the suggested mode of action of lactoferrin (Lf) in nonsmall cell lung cancer (NSCLC) A549 cells. Lf induces activation of caspase‐3 by activating p53 and AChE leading to decreased ACh concentrations. In turn, ACh signaling leads to activation of VEGF and AKT and blocking of caspase‐3.

Topological interface modes in 3D-printed triply periodic minimal surface phononic crystals

Materials & Design
Triply periodic minimal surface (TPMS)-based continuous structures have recently attracted increased attention due to their remarkable mechanical properties, such as high strength-to-weight ratio, impact resistance, and energy absorption capabilities. In
