Nutritional Dermatology: Optimizing Dietary Choices for Skin Health.

Background/objectives: Youthful, smooth skin is highly desired in modern society. Individuals invest in cosmetics, plastic surgeons, and dermatologists in pursuit of perfect skin. However, many do not seek out dietary changes to improve skin health.

High-Valent Cobalt-Difluoride in Oxidative Fluorination of Saturated Hydrocarbons.

The heme paradigm where Fe=O acts as the C-H oxidant and Fe-OH rebounds with the formed carbon-centered radical guides the design of the prototypical synthetic hydroxylation catalyst. We are exploring methods to evolve beyond the metal-oxo oxidant and hydroxide rebound, to incorporate a wider array of functional group. We have demonstrated the application of Co(OTf) (10 mol% catalyst; OTf=trimfluoromethanesulfonate) in combination with polydentate N-donor ligands (e.

Osteosarcopenic adiposity and its relation to cancer and chronic diseases: Implications for research to delineate mechanisms and improve clinical outcomes.

This is the third review in our series examining the connection between osteosarcopenic adiposity/obesity (OSA/OSO) syndrome and health impairments. The objective here was to examine whether there is a causal and/or bidirectional relationship between OSA and some chronic diseases. The search (in PubMed, Scopus, and WoS), screened for articles from their inception to the end of February 2024.

Biodiversity impacts of the 2019-2020 Australian megafires.

With large wildfires becoming more frequent, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented 2019-2020 Australian megafires burnt more than 10 million hectares, prompting major investment in biodiversity monitoring.

A Structural and Functional Mimic of P680.

One or multiple chlorophyll a molecules are employed in the reaction center of photosystem II's main electron donor (defined as P680). We have a poor understanding of how the reaction center facilitates water oxidation in photosystem II and the roles that mono- and/or multimeric chlorophyll groups play when P680 oxidizes a neighboring tyrosine in order to drive water oxidation at the oxygen evolving complex. We have prepared a dimeric Mg-porphyrin complex [Mg(BTPP)] (1, H-BTPP=1,2-bis-(10,15,20-triphenylporphyrin-5-yl)-benzene) as a structural and functional mimic of the dimeric core of P680.
