Spherical implantable collamer lens with postoperative adjunctive LASIK in the treatment of high compound hyperopic astigmatism.

Objective: To assess refractive and visual outcomes of a spherical Implantable Collamer Lens (ICL) followed by planned postoperative adjunctive laser-assisted in situ keratomileusis (LASIK) in the treatment of high compound hyperopic astigmatism.

Methods: In this prospective, multi-center, multi-surgeon, single-arm trial, eyes with ≥ 3.50 D hyperopia and ≥ 2.

Functional heterogeneity of mesenchymal stem cells and their therapeutic potential in the K18-hACE2 mouse model of SARS-CoV-2 infection.

Background: Despite many years of investigation into mesenchymal stem cells (MSCs) and their potential for treating inflammatory conditions such as COVID-19, clinical outcomes remain variable due to factors like donor variability, different tissue sources, and diversity within MSC populations. Variations in MSCs' secretory and proliferation profiles, and their proteomic and transcriptional characteristics significantly influence their therapeutic potency, highlighting the need for enhanced characterization methods to better predict their efficacy. This study aimed to evaluate the biological characteristics of MSCs from different tissue origins, selecting the most promising line for further validation in a K18-hACE2 mouse model of SARS-CoV-2 infection.

Structural Insights and Potential Inhibitor Identification Based on the Benzothiazole Core for Targeting Pteridine Reductase 1.

Leishmaniasis is reported as the second most common protozoonosis, with the highest prevalence and mortality rate. Among the Leishmania drug targets, Pteridine Reductase 1 of (PTR1) proved to be promising because Leishmania is auxotrophic for folates. Thus, this study employed a combination of ligand- and structure-based approaches to screen new benzothiazole compounds as PTR1 inhibitor candidates.

Suspect screening and quantitative analysis of 165 contaminants of emerging concern in water, sediments, and biota using LC-MS/MS: Ecotoxicological and human health risk assessment.

This study aimed to implement a targeted multiple reaction monitoring (MRM) screening strategy using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) for the initial detection of 165 compounds of emerging concern (CECs) in water, sediment, and fish samples. Following the screening, confirmatory and quantitative analyses were conducted using analytical standards for the detected compounds. Qualitative results were confirmed using high-resolution mass spectrometry (HRMS) for those CECs without available standards.

Harnessing the synergy of Urochloa brizantha and Amazonian Dark Earth microbiomes for enhanced pasture recovery.

Amazonian Dark Earths (ADEs) are fertile soils from the Amazon rainforest that harbor microorganisms with biotechnological potential. This study aimed to investigate the individual and potential synergistic effects of a 2% portion of ADEs and Urochloa brizantha cv. Marandu roots (Brazil's most common grass species used for pastures) on soil prokaryotic communities and overall soil attributes in degraded soil.
