High intraocular pressure (HIOP) and high glucose levels are associated with oxidative stress. Although physical exercise protects against oxidative damage, its specific impact on eye health remains unclear. Thus, this study aimed to assess the impact of physical exercise on the oxidative status of whole eyes in male Swiss mice subjected to HIOP model and cafeteria diet (CD).

The frequency and intensity of wildfires have been increasing in many parts of the world, which may result in biodiversity loss. Wildfires can devastate plant communities, generating toxic ash that pollutes watercourses through runoff. However, our understanding of the effects of ash exposure on aquatic biodiversity is still limited.

This study investigates the effect of chloride levels on the mode of action of palladium complexes for the activation of propargyl- and allene-protected fluorophores and chemotherapeutic drugs through uncaging reactions. Four Pd(II) complexes were synthesized and characterized using various spectroscopic techniques to confirm their structure and electronic properties. Kinetic studies and density functional theory calculations revealed that chloride ions in phosphate buffered saline (PBS) significantly enhance catalytic efficiency, particularly for allenyl-protected substrates compared to propargylic counterparts.

Some native Chilean berries, including murtilla, have gained attention for their high phenolic content which renders them attractive for the beverage industry. However, phenolic-rich by-products are generated during the production of murtilla juice (murtilla pomace), and there has been no scientific consideration of this by-product as a source of different forms of phenolic compounds. The aim of this study was thus to obtain phenolic extracts from the soluble fraction (free, esterified, and etherified) of murtilla pomace as well from the counterpart that contains insoluble-bound compounds, and evaluate their antioxidant properties.

We propose a novel solution to streamline the migration of existing Transport Layer Security (TLS) protocol implementations to a post-quantum Key Encapsulation Mechanism for Transport Layer Security (KEMTLS). By leveraging Identity-Based Encryption (IBE), our solution minimizes the necessary modifications to the surrounding infrastructure, enabling the reuse of existing keys and certificates. We provide a proof-of-concept implementation and performance analysis, demonstrating the practical feasibility and effectiveness of our proposed approach.

This manuscript evaluated the performance of silanes in cementitious matrices in the partial replacement of superplasticizers by silanes. For this, pastes with a water/cement ratio of 0.186 were produced and the superplasticizer admixture based on polycarboxylate esters was partially substituted by three types of silanes-vinyltriethoxysilane silanes (VTES), n-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS), and methacryloxypropyltrimethox-ysilane (MCPTMS)-in two substitutions levels (20% and 40%), and then tested in Portland cement pastes.

The jaboticaba is a fruit with a highly promising chemical profile for producing fermented products with biological activity. In this context, evaluating pre-fermentative maceration techniques in jaboticaba fermentations is essential to optimize the extraction of phenolic compounds and other metabolites of interest, imparting antioxidant characteristics to the product and offering potential health benefits. This study evaluated the impact of two pre-fermentative maceration techniques on the phenolic composition, bioaccessibility, and biological activities (α-amylase, α-glucosidase, and ACE inhibition) of alcoholic and acetic fermented products from jaboticaba.

Piezoresistive pressure sensors have been prepared by the electrospinning of poly(vinylidene fluoride) (PVDF) containing graphene nanoplatelets (GNP) functionalized using 1-butyl-3-methylimidazolium trifluoromethanesulfonate (BMIM(OTf)) ionic liquid (IL). Optical microscopy demonstrated that the functionalized GNP powder presented particles with a smaller lateral size. The obtained mats were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, differential scanning calorimetry, electrical resistivity using two and four probes, and electromechanical testing with up to 32 load-unload cycles.

In the pursuit of advancing sustainable wastewater treatment solutions in the industry, this study investigates the effect of chemical and thermal modifications on adsorbent geopolymer (GP) structure. Optimal conditions of sulfuric acid treatment and calcination temperature were determined to enhance the adsorption of the direct red dye 28 (DR28). Functional groups (FTIR), mineralogical composition (DRX), morphology (SEM-EDS), and physical properties (BET/BJH) were employed to study the effect of attack with HSO and calcination on GP characteristics.

Methods: The search for scientific articles was carried out by 2 independent researchers in electronic databases. Meta-analysis was performed by constructing summary risk measures for each vitamin or antioxidant, combining the risk ratios or adjusted odds ratios (OR) for the various variables observed in the highest categories of vitamin or antioxidant consumption.

Vascular hamartoma is an abnormal development of endothelial tissue that rarely affects horses. Histopathological examination remains the gold standard for definitive diagnosis, yet the presence of abnormal vascular structures must be carefully differentiated from other vascular anomalies and neoplasms. This report describes two cases of vascular proliferation affecting the skin on the lateral side over the left tarsus and the dorsolateral region over the fetlock joint of two fillies.

The purpose of this study was to investigate the influence of the color of positioning guides on the CIEL*a*b* color coordinates of ceramic, resin composite and bovine tooth surfaces measured by a clinical spectrophotometer. Positioning guides (n=10) in different colors (translucent, purple, yellow, green and, blue) were made for each surface (ceramic, resin composite and bovine tooth). The CIEL*a*b* color coordinates were measured with the positioning guides and with no positioning guide (control group).
