Marine Alga Ecklonia cava Extract and Dieckol Attenuate Prostaglandin E₂ Production in HaCaT Keratinocytes Exposed to Airborne Particulate Matter

Antioxidants, 2019
Atmospheric particulate matter (PM) is an important cause of skin damage, and an increasing number of studies have been conducted to discover safe, natural materials that can alleviate the oxidative stress and inflammation caused by PM.

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

Advanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.

Towards topological Hochschild homology of Johnson-Wilson spectra [PDF]

Algebr. Geom. Topol. 20 (2020) 375-393, 2018
We offer a complete description of $THH(E(2))$ under the assumption that the Johnson-Wilson spectrum $E(2)$ at a chosen odd prime carries an $E_\infty$-structure. We also place $THH(E(2))$ in a cofiber sequence $E(2) \rightarrow THH(E(2))\rightarrow \overline{THH}(E(2))$ and describe $\overline{THH}(E(2))$ under the assumption that $E(2)$ is an $E_3 ...

Signal pathways JNK and NF-κB, identified by global gene expression profiling, are involved in regulation of TNFα-induced mPGES-1 and COX-2 expression in gingival fibroblasts

BMC Genomics, 2010
Background Prostaglandin E2 (PGE2) is involved in several chronic inflammatory diseases including periodontitis, which causes loss of the gingival tissue and alveolar bone supporting the teeth. We have previously shown that tumor necrosis factor α (TNFα)

Regulation of renal function by prostaglandin E receptors [PDF]

Kidney International, 1998
Prostaglandin E2 is the major cyclooxygenase product of arachidonic acid metabolism produced along the nephron. This autacoid interacts with four distinct, G-protein-coupled E-prostanoid receptors designated EP1-EP4. The intrarenal distribution of each receptor has been mapped and the consequences of receptor activation examined.

Bee Better: The Role of Honey in Modern Wound Care

Advanced Therapeutics, EarlyView.
The use of honey as a wound care agent is controversial but paradoxically increasingly popular. Honey possesses relevant antimicrobial properties and can modulate the immune system. The wound healing properties of honey likely depend on its composition and varies across wound types.

b-Property of sublattices in vector lattices [PDF]

arXiv, 2021
We study $b$-property of a sublattice (or an order ideal) $F$ of a vector lattice $E$. In particular, $b$-property of $E$ in $E^\delta$, the Dedekind completion of $E$, $b$-property of $E$ in $E^u$, the universal completion of $E$, and $b$-property of $E$ in $\hat{E}(\hat{\tau})$, the completion of $E$.

Prostaglandins and related factors: XIX. Thin-layer chromatography of prostaglandins

Journal of Lipid Research, 1964
Methods are described for separation of all known prostaglandins and some derivatives as free acids and methyl esters by thin-layer chromatography both on analytical and preparative scales. The use of silica gel containing silver nitrate was required for

Accelerated Bone Healing via Electrical Stimulation

Advanced Science, EarlyView.
Electrical stimulation significantly impacts bone healing by enhancing osteoblast proliferation, differentiation, and vascularization through calmodulin/calcineurin/NFAT signaling. It also boosts macrophage function and cell migration, presenting a comprehensive approach to accelerating bone repair.

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production [PDF]

Journal of Neuroimmunology 174(1-2): 39-51 (2006), 2007
In the present study, we show that ascorbic acid dose-dependently inhibited interleukin-1beta (IL-1beta)-mediated PGE2 synthesis in the human neuronal cell line, SK-N-SH. Furthermore, in combination with aspirin, ascorbic acid augmented the inhibitory effect of aspirin on PGE2 synthesis. However, ascorbic acid had no synergistic effect along with other
