Understanding the interactions between transition metal atoms and molecules is important for the study of various related chemical and physical processes. In this study, we have investigated collisions between iron (Fe), iridium (Ir), and platinum (Pt) and the small molecules CH, O, and CO using a crossed-beam and time-sliced ion velocity map imaging technique. Elastic collisions were observed in all cases, except for collisions of Pt with O and CO.

Background: Neuroblastoma (NB) is a highly heterogeneous and common pediatric malignancy with a poor prognosis. Ferroptosis, an iron-dependent cell death pathway, may play a crucial role in NB tumor progression and immune response. This study aimed to investigate ferroptosis in NB to identify potential therapeutic targets and develop predictive models for prognosis and recurrence.

Department of Health Promotion, Education, and Behavior, University of South Carolina, Columbia, SC, USA.
Background: Reducing inequalities in women's nutrition and health care can accelerate progress towards Sustainable Development Goals for maternal and child health. Nutrition interventions for women are delivered through maternal health services such as antenatal care and institutional deliveries, but whether they reach and protect the disadvantaged against malnutrition is not well documented.
Objective: To assess the similarities in socioeconomic disparities and inequalities in the nutritional status and health care of women.
Combined Toxicity Assessment of Deoxynivalenol and Pb on HK-2 Cells Involved in Excessive ROS-Induced Ferroptosis.

Institute for Agro-food Standards and Testing Technology, Shanghai Academy of Agricultural Sciences, 1000 Jingqi Road, Shanghai 201403, China.
The cocontamination of food by several mycotoxins and heavy metals poses significant health risks, and their combined toxic effects remain poorly understood. Particularly, specific studies exploring their combined impact on ferroptosis remain limited. In this work, we investigated the combined toxic effects of a mycotoxin, called deoxynivalenol (DON), and a heavy metal, called plumbum (Pb), and explored the potential mechanisms of DON and Pb co-occurrence via excessive ROS-induced ferroptosis in HK-2 cells.

-Armchair graphene nanoribbons (nAGNRs) are promising components for next-generation nanoelectronics due to their controllable band gap, which depends on their width and edge structure. Using non-metal surfaces for fabricating nAGNRs gives access to reliable information on their electronic properties. We investigated the influence of light and iron adatoms on the debromination of 4,4''-dibromo--terphenyl precursors affording poly(-phenylene) (PPP as the narrowest GNR) wires through the Ullmann coupling reaction on a rutile TiO(110) surface, which we studied by scanning tunneling microscopy and X-ray photoemission spectroscopy.
