Methane to Methanol Transformation on Cu2+/H-ZSM-5 Zeolite. Characterization of Copper State and Mechanism of the Reaction.

Cu-modified zeolites provide methane conversion to methanol with high selectivity under mild conditions. The activity of different possible Cu-sites for methane transformation is still under discussion. Herein, ZSM-5 zeolite has been loaded with Cu2+ cations (1.

Novel Anthraquinone Derivatives and Their Complexes with Metal Ions with Anticancer Activity: Structure/Redox and Chelation Activity Correlations.

Some specific anthraquinone derivatives (AQs) are known to be used widely as effective chemotherapeutic agents in the treatment of cancer. However, their fundamental shortcoming is the high rate of cardiotoxicity observed in treated patients, which is thought to be caused by the increase in production of reactive oxygen species (ROS) catalyzed by iron and copper. The development of improved AQs and other anticancer drugs with enhanced efficacy but reduced toxicity remains a high priority.

The Impact of Marriage on Breastfeeding Duration: Examining the Disproportionate Effect of COVID-19 Pandemic on Low-Income Communities.

Marriage promotes breastfeeding duration through economic and social supports. The COVID-19 pandemic disproportionately affected marginalized communities and impacted women's employment and interpersonal dynamics. This study examined how marital status affects breastfeeding duration across socioeconomic and racially minoritized groups during COVID-19, aiming to inform social support strategies for vulnerable families in public health crises.

The impact of marriage on breastfeeding duration: examining the disproportionate effect of COVID-19 pandemic on marginalized communities.

Background: Marriage promotes breastfeeding duration through economic and social supports. The COVID-19 pandemic disproportionately affected marginalized communities and impacted women's employment and interpersonal dynamics. This study examined how marriage affects breastfeeding duration across socioeconomic and racially minoritized groups during COVID-19, aiming to inform social support strategies for vulnerable families in public health crises.

Ultrastructural Remodeling of Cardiomyocytes in Postinfarction Myocardium of Rats in the Late Stages of the Disease.

Identifying factors that contribute to the transition to the dilated phase in cardiac ischemia is a critical challenge in heart failure treatment. Currently, no effective therapies exist for this ischemic complication, and the mechanisms driving left ventricular dilatation during chronic post-infarction remodeling remain poorly understood. One potential pathological process leading to ventricular dilatation involves specific compensatory rearrangements in the border zone adjacent to the infarct, which isolates the intact myocardium from inflammation at the scar edge.
