Deep eutectic solvents (DES) are a new class of green solvents that have shown unique properties in several process applications. This study evaluates nonionic DES containing phenolic alcohols as solvents for carbon dioxide (CO) capture applications. Potential phenolic alcohols and the molar ratio between DES constituents were preselected for experimental investigations based on the conductor-like screening model for realistic solvation (COSMO-RS). CO solubility was experimentally determined in two different DES, namely, L-menthol/thymol in 1:2 molar ratio and thymol/2,6-xylenol in 1:1 molar ratio, at various temperatures and pressures. CO solubility in the studied systems was higher than that reported in the literature for ionic DES and ionic liquids. This study demonstrates that nonionic DES containing phenolic alcohols can be excellent, inexpensive, and simple solvents for CO capture.

Context: Dopamine -monooxygenase (D M) is an essential enzyme in the organism that regioselectively converts dopamine into R-norepinephrine, the key step of the reaction, studied in this paper, is a hydrogen atom transfer (HAT) from dopamine to a superoxo complex on D M, forming a hydroperoxo intermediate and dopamine radical. It was found that the formation of a hydrogen bond between dopamine and the D M catalyst strengthens the substrate-enzyme interaction and facilitates the HAT which takes place selectively to give the desired enantiomeric form of the product. Six reactions leading to the hydroperoxo intermediate were analyzed in detail using theoretical and computational tools in order to identify the most probable reaction mechanism.

Importantly, the LC is the main noradrenergic nucleus in the brain and source of NE in the forebrain, and dysregulation of the neurotransmitter norepinephrine (NE) is associated with AD symptoms, as its release in the forebrain regulates attention, arousal, stress response, and learning and memory. Moreover, the LC may transmit pathogenic tau to the forebrain via its extensive projections.

Early detection and intervention are vital for effective management. Recent research has identified the Locus Corelulus (LC) as one of the initial sites of pathology in AD, characterized by the degeneration of norepinephrine (NE) producing cells, resulting in cognitive and mood disturbances.

Background: Early stages of Alzheimer's disease (AD) are characterized by neuropsychiatric symptoms such as anxiety, apathy, compulsivity, and sleep disturbances, which manifest years before cognitive deficits. It has been hypothesized that dysregulation of the locus coeruleus-norepinephrine (LC-NE) system contributes to these symptoms because (1) the LC is the first site where hyperphosphorylated 'pretangle' tau can be detected in the human brain and (2) NE influences physiological processes such as mood, stress responses, and arousal. To investigate causal relationships between LC tau pathology and neuropsychiatric symptoms, we developed a translationally-relevant model where pathogenic tau is exclusively expressed in mouse LC to recapitulate the 'LC-first' phenomenon.
