The role of UV-induced cutaneous matrix metalloproteinases and mi-RNAs in the pathogenesis of lupus erythematosus.

Cutaneous (CLE) and systemic lupus erythematosus (SLE) are autoimmune diseases with a multifactorial pathogenesis. Ultraviolet radiation (UVR) is the most important trigger of CLE; however, the degree of photosensitivity varies between the clinical subtypes. The expression of matrix metalloproteinases (MMPs)-important enzymes involved in skin turnover and homeostasis-is modulated by UVR.

Using the Radial Distribution Function to Analyze Atomic Force Microscopy Images of Colloidal Systems.

Biomacromolecules generally exist and function in aqueous media. Is it possible to estimate the state and properties of molecules in an initial three-dimensional colloidal solution based on the structure properties of biomolecules adsorbed on the two-dimensional surface? Using atomic force microscopy to study nanosized objects requires their immobilization on a surface. Particles undergoing Brownian motion in a solution significantly reduce their velocity near the surface and become completely immobilized upon drying.

Antimicrobial and Oxidative Activities of Different Levels of Silver-Exchanged Zeolites X and ZSM-5 and Their Ecotoxicity.

Objectives: The antimicrobial, oxidative activities, and ecotoxicity of synthesized silver-loaded zeolites (X and ZSM-5(MFI), Si-to-Al ratios 12 and 25) were studied, linking antimicrobial properties to material structure and released active silver species.

Methods: The materials were characterized by SEM, EDX, TEM, and XRPD. All materials, with a silver content of 1-3%wt for the Ss and about 35%wt for the X-zeolites, were tested against and .

Automatic and strategic components of bilingual lexical alignment.

Second-language speakers are more likely to strategically reuse the words of their conversation partners (Zhang & Nicol, 2022). This study investigates if this is also the case for lower-proficiency bilinguals from a bilingual community, who use language more implicitly, and if there is more alignment with lower than with higher proficiency, provided the words to be aligned to are all highly familiar. In two experiments, Spanish-English bilinguals took turns with a confederate to name and match pictures in Spanish.

Passive acoustic monitoring for seabed bubble flows: Case of shallow methane seeps at Laspi Bay (Black Sea).

This research quantifies the gas release rate from a natural shallow methane seep site in the Laspi Bay (Black Sea), whose origin is thermocatalytic. An adaptive single bubble identification technique was applied to analyze gas volume and release rates from passive acoustic data. Gas from the seafloor was emitted by single bubbles that occurred in clusters.
