Properties of surface layers of duplex stainless steel after burnishing processes
PublikacjaStress corrosion cracking resistance of cold worked layers of 25 Cr duplex stainless steel grade UR52N+ has been investigated. The surface layers were performed through burnishing treatment. The residual stresses at surface layers were determined using grazing angle incidence X-ray diffraction method (g-sin2 Ψ). Corrosion tests were performed with the use of Slow Strain Rate Test technique in boiling 35% MgCl2 solution. It has...

Rhodotorulic Acid and its Derivatives: Synthesis, Properties, and Applications
PublikacjaSiderophores are low molecular weight compounds produced by microorganisms to scavenge iron in iron-deficient environments. Rhodotorulic acid, a natural hydroxamate siderophore, plays a vital role in iron acquisition for fungi and bacteria. As the simplest natural hydroxamate siderophore, it exhibits a high affinity for ferric ions, enabling it to form stable complexes that facilitate iron uptake and transport within microorganisms....

Modulation of cellular response to anticancer treatment by caffeine:inhibition of cell cycle checkpoints, DNA repair and more
PublikacjaKofeina i inne metyloksantyny wywołują bardzo różne efekty fizjologiczne w organizmie człowieka. W pracy przedstawiamy, które z tych efektów mogą wpływać na skuteczność terapii przeciwnowotworowych. Kofeina może bezpośrednio wpływać na transport oraz aktywację metaboliczną cząsteczek leków do komórki, poprzez tworzenie kompleksów z lekami zawierającymi układy poliaromatyczne. Kofeina hamuje aktywność kinaz ATM/ATR co prowadzi do...
