Impact of multi-micronutrient supplementation on lipidemia of children and adolescents

Background: Micronutrient supplementation has been extensively explored as a strategy to improve health and reduce risk of chronic diseases. Fat-soluble vitamins like A and E with their antioxidant properties and mechanistic interactions with lipoproteins, ...

Discovery and validation of temporal patterns involved in human brain ketometabolism in cerebral microdialysis fluids of traumatic brain injury patients

Sarah Catherine Sonnay, Anirikh Chakrabarti, Nicolas Christinat, Mojgan Masoodi

Background: Traumatic brain injury (TBI) is recognized as a metabolic disease, characterized by acute cerebral glucose hypo-metabolism. Adaptive metabolic responses to TBI involve the utilization of alternative energy substrates, such as ketone bodies. Cer ...

Nutritional Ketosis Increases NAD+/NADH Ratio in Healthy Human Brain: An in Vivo Study by 31P-MRS

Rolf Gruetter, Lijing Xin, Özlem Ipek, Mojgan Masoodi, Nicolas Christinat, Maya Shevlyakova

Ketones represent an important alternative fuel for the brain under glucose hypo-metabolic conditions induced by neurological diseases or aging, however their metabolic consequences in healthy brains remain unclear. Here we report that ketones can increase ...

Self-assembly of boron-based supramolecular structures

Nicolas Christinat

This work describes the synthesis and characterization of boronic acid-based supramolecular structures. Macrocycles, dendritic structures, polymers, rotaxanes, and cages were assembled using four types of reversible reactions. The key point of the strategy ...

Formation of Boronate Ester Polymers with Efficient Intrastrand Charge Transfer Transitions by Three-Component Reactions

Rosario Scopelliti, Ursula Röthlisberger, Kay Severin, Michele Cascella, Nicolas Christinat, Emmanuel Croisier

The three-component reaction of aryl boronic acids with 1,2,4,5-tetrahydroxybenzene and 1,2-bis(4-pyridyl)ethylene or 4,4-bipyridine leads to the formation of dark-purple boronate ester polymers. Crystallographic analyses show that the polymer strands have ...

A new method for the synthesis of boronate macrocycles

Rosario Scopelliti, Kay Severin, Nicolas Christinat

The condensation of aryl boronic acids with 2,3-dihydroxypyridine gives boronates, which self-assemble to form tetrameric macrocycles as evidenced by X-ray crystallographic analyses. ...
