Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Ketone Administration for Seizure Disorders: History and Rationale for Ketone Esters and Metabolic Alternatives

open access: yesFrontiers in Neuroscience, 2019
The ketogenic diet (KD) is a high-fat, low-carbohydrate treatment for medically intractable epilepsy. One of the hallmark features of the KD is the production of ketone bodies which have long been believed, but not yet proven, to exert direct anti ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Safety Evaluation of Repeated Application of Polymeric Microarray Patches in Miniature Pigs

open access: yesAdvanced Healthcare Materials, EarlyView.
This study demonstrates the safety of repeated application of three types of microarray patches (MAPs), hydrogelforming, dissolving, and implantable, over four weeks in miniature pigs. No adverse skin or systemic effects were observed, supporting the clinical potential of MAPs as safe and effective drug delivery platforms.

Facile Palladium-Mediated Conversion of Ethanethiol Esters to Aldehydes and Ketones

open access: yesJournal of the Brazilian Chemical Society, 1998
Treatment of ethanethiol esters with triethylsilane and palladium on carbon at ambient temperature furnished aldehydes. In addition, a variety of ketones have been prepared by a palladium-catalyzed reaction of ethanethiol esters with organozinc reagents.

In pursuit of β-amino α-nitro β-trifluoromethyl ketones: nitro-Mannich vs Mannich-type reactions [PDF]

open access: yes, 2017
The reactivity of alfa-nitro ketones with trifluoromethyl aldimines is studied for the first time. While under nitro-Mannich conditions only the facial stereoselectivity can be controlled, organocatalysed Mannich-type reactions allowed a complete control

A Ketone Ester Drink Lowers Human Ghrelin and Appetite

open access: yesObesity, 2017
The ketones d‐β‐hydroxybutyrate (BHB) and acetoacetate are elevated during prolonged fasting or during a “ketogenic” diet. Although weight loss on a ketogenic diet may be associated with decreased appetite and altered gut hormone levels, it is unknown ...
