Functionalization of zeolite-encapsulated Cu clusters as visible-light photoactive sub-nanomaterials.

The unique structural properties of zeolites make them ideal environments for encapsulating subnanometric metal clusters on their microporous channels and cavities, showing an enhanced catalytic performance. As a first step towards the functionalization of these clusters as photocatalysts as well, this work addresses the optical properties of zeolite-encapsulated Cu-TiO nanoparticles as well as their application in the photo-induced activation of CO by sunlight. Model density functional theory (DFT) calculations indicate the stability of the Cu cluster adsorbed on the TiO nanoparticles filling the pores of a model zeolite structure.

Greater and Earlier Exposure of Mother's Own Milk Compared to Donor Human Milk Moderates Risk and Severity of Bronchopulmonary Dysplasia.

Bronchopulmonary dysplasia (BPD) is a common complication of preterm very low birth weight (VLBW) infants. Mother's own milk (MOM) may mitigate the severity of BPD. Pasteurized donor human milk (PDHM) is often used as an alternative when MOM is unavailable with limited information on the influence of PDHM on BPD risk and severity.

Nurse Faculty Perceptions of Anxiety in Nursing Students.

Anxiety in nursing students can interfere with the development of the knowledge, skills, and clinical judgment necessary to practice in a complex health care environment. Thirteen faculty from nursing programs across one state were interviewed to explore faculty perceptions of anxiety among prelicensure baccalaureate nursing students. Data analysis from this qualitative study showed that faculty recognized anxiety in students and its contributing factors.

Breast cancer metastasis progression is associated with elevated activity of kynurenine monooxygenase and kynureninase.

Introduction: Metastasis remains the major cause of death in breast cancer (BrCa) and lacks specific treatment strategies. The kynurenine pathway (KP) has been suggested as a key mechanism facilitating progression of BrCa. While KP activity has been explored in primary BrCa, its role in metastasis remains unclear.
