Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Plasma-activated polymer films for mesenchymal stem cell differentiation [PDF]

, 2014
Polyetheretherketone (PEEK) is a biomaterial utilized for spine, orthopedic and trauma implants. Its inertness prevents osseointegration, so that coatings with titanium or hydroxyapatite are required for load-bearing PEEK implants.

Improved Adhesion of Bacterial Cellulose on Plasma-Treated Cotton Fabric for Development of All-Cellulose Biocomposites

Molecules
Cellulose produced by bacteria (BC) is considered a promising material for the textile industry, but the fragile and sensitive nature of BC membranes limits their broad applicability.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Production of Micro Nanofibrillated Cellulose from Prerefined Fiber via a Dry Dielectric Barrier Discharge (DBD) Oxygen Plasma-Treated Powder Precursor

Journal of Natural Fibers
Cellulose is a strong contender for the development of sustainably resourced biodegradable material composites supporting circular economy. Nanofibrillar cellulose-comprising materials are among the most promising lignocellulose derivatives.

Influence of Plasma Treatment on Physical Properties of Thin SnO2 Films Obtained from SnCl4 Solutions with Additions of NH4F and NH4OH

Eurasian Chemico-Technological Journal, 2019
This paper considers the effect of oxygen and hydrogen plasma on SnO2 films synthesized from solutions of tin tetrachloride containing NH4F and NH4OH additives. It was found that the treatment of samples with oxygen plasma for 5 min led to a decrease in

Extracellular vesicle lipidomics liquid biopsy reveals systemic and tumor microenvironment metabolic reprogramming in ovarian cancer

Molecular Oncology, EarlyView.
Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.

Modelling of induction thermal plasma synthesis of iron nanoparticles in oxygen-contaminated gas mixtures [PDF]

, 2017
The synthesis of iron nanoparticles in a radio-frequency induction thermal plasma (RF-ITP) system working in a mixture of argon contaminated with oxygen (10-100 ppm) has been modelled considering the iron oxidation reactions both in gaseous and ...
