The lysyl oxidase (LOX) gene family encodes for a group of copper-dependent enzymes that play a crucial role in the cross-linking of collagen and elastin fibers in the extracellular matrix (ECM). Dysregulation of LOX gene expression has been implicated in various pathological conditions, including cancer. Several studies have shown that the LOX gene family is involved in cancer progression and metastasis.

Article Synopsis
  • The study examined the creep properties of ZK60 alloy and its composite with SiC at temperatures of 200 °C and 250 °C under varying stress levels (10-80 MPa) following KOBO extrusion and precipitation hardening.
  • Both the unreinforced alloy and the SiC composite exhibited true stress exponents between 1.6 and 2.3, and their activation energies suggested that grain boundary sliding (GBS) was a significant mechanism.
  • Microstructural analysis revealed that at 200 °C, low-stress conditions led to the formation of twins and shear bands, while at 250 °C, slip bands developed, indicating mechanisms delaying GBS; failure was primarily attributed to cavity nucle

One of the materials that has recently been used to remove environmental pollution from industrial effluents with photocatalytic technology is cobalt chromate (CoCrO) nanoparticles. An effective way to improve the photocatalytic properties of materials is to composite them with other photocatalysts to prevent recombination of electron-holes and accelerate the transfer of oxidation/reduction agents. Graphitic carbon nitride (g-CN) is an excellent choice due to its unique properties.

Aim: Ferroptosis is increasingly becoming to be considered as an important mechanism of pathological cell death during stroke, and specific exogenous ferroptosis inhibitors have the ability to reverse cerebral ischemia/reperfusion injury. However, research on Srs11-92 (AA9), a ferrostatin-1 (Fer-1) analog, in preclinical studies is limited.

Methods: In the middle cerebral artery occlusion-reperfusion (MCAO/R) mice model or oxygen-glucose deprivation/reperfusion (OGD/R) cell model, Fer-1, AA9, and/or ML385 were administered, and brain infarct size, neurological deficits, neuronal damage, oxidative stress, and neuroinflammation were determined after the damage, in vitro and in vivo.

One of the most important methods of controlling the properties of concrete and cement-based materials is to control the rate and kinetics of cement hydration. In the present study, novel flexible polyurethane-decorated MgO nanohybrids were synthesized using a simple chemical method, added to cement paste in different amounts, and utilized as an effective mechanical performance-enhancing factor for cement paste. It was observed that by adding 3 wt% synthesized PU-MgO nanohybrids to cement paste, its mechanical properties were improved and its compressive strength and flexural strength were increased by up to 13% and 15%, respectively, compared to the plain cement, after 45 days.
