The limited mass transfer of CO and the competitive hydrogen evolution reaction (HER) during photoelectrochemical (PEC) CO reduction usually result in low CO reduction activity. Here, we constructed a CuO/Sn/PTFE photocathode with a hydrophobic surface based on CuO by physical vapor deposition and a dipping method. The CO faradaic efficiency (FE) increased from 34.5% (CuO) to 95.1% (CuO/Sn/PTFE) at -0.7 V RHE, and the FE decreased from 27.9% (CuO) to 3.8% (CuO/Sn/PTFE). The introduction of the hydrophobic layer enhances the local CO concentration on the electrode surface and effectively isolates H from the aqueous electrolyte, thereby enhancing the CO reduction activity.

Farnesol (FAR) belongs to terpenes group and is a sesquiterpene alcohol and a hydrophobic compound, which can be extracted from natural sources or obtained by organic chemical or biological synthesis. Recent advances in the field of nanotechnology allow the drawbacks of low drug solubility, which can improve the drug therapeutic index. Therefore, this study aimed to prepare the FAR inclusion complexes with β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) through freeze-drying method, proposing their physicochemical characterization, comparing their toxicity, and evaluating their in vitro antibacterial activity.

5-Fluorouracil (5-FU) is a chemotherapeutic that is used to treat solid tumors. However, 5-FU is associated with several side effects, including cardiotoxicity. Considering the importance of the intrinsic cardiac nervous system (ICNS) for the heart and that little is known about effects of 5-FU on this nervous system plexus, the purpose of the present study was to evaluate effects 5-FU at a low dose on the ICNS and oxidative and inflammatory effects in the heart in Wistar rats.

Background: SHEN26 (ATV014) is an oral RNA-dependent RNA polymerase (RdRp) inhibitor with potential anti-SARS-CoV-2 activity. Safety, tolerability, and pharmacokinetic characteristics were verified in a Phase I study. This phase II study aimed to verify the efficacy and safety of SHEN26 in COVID-19 patients.

Background: The World Health Organization conditionally recommends reactive drug administration to reduce malaria transmission in settings approaching elimination. However, few studies have evaluated the impact of reactive focal drug administration (rFDA) in sub-Saharan Africa, and none have evaluated it under programmatic conditions. In 2016, Senegal's national malaria control programme introduced rFDA, the presumptive treatment of compound members of a person with confirmed malaria, and reactive mass focal drug administration (rMFDA), an expanded effort including neighbouring compounds during an outbreak, in 10 low transmission districts in the north of the country.

As the earliest measure of social communication in rodents, ultrasonic vocalizations (USVs) in response to maternal separation are critical in preclinical research on neurodevelopmental disorders (NDDs). While sex differences in both USV production and behavioral outcomes are reported, many studies overlook sex as a biological variable in preclinical NDD models. We aimed to evaluate sex differences in USV call parameters and determine if USVs are differently impacted based on sex in the preclinical maternal immune activation (MIA) model.
