Enantioselective Reductive Alkenylation of α‐CF2H (‐CF3) Amino Halides: Rapid Access to Chiral α‐CF2H (‐CF3) Allylamines

open access: yesAdvanced Science, EarlyView.
Difluoromethyl (CF2H) group, the bioisostere of hydroxyl thiol methyl or amide is privileged in medicinal chemistry due to hydrogen‐binding ability and lipophilic, metabolically stable, and chemical inert nature. However, enatioseleceive CF2H introduction remains challenging.

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

Menthol facilitates the intravenous self-administration of nicotine in rats

open access: yesFrontiers in Behavioral Neuroscience, 2014
Menthol is preferred by approximately 25% of smokers and is the most common flavoring additive in tobacco and electronic cigarettes. Although some clinical studies have suggested that menthol facilitates the initiation of smoking and enhances the ...

Menthol Alone Upregulates Midbrain nAChRs, Alters nAChR Subtype Stoichiometry, Alters Dopamine Neuron Firing Frequency, and Prevents Nicotine Reward [PDF]

open access: yes, 2016
Upregulation of β2 subunit-containing (β2*) nicotinic acetylcholine receptors (nAChRs) is implicated in several aspects of nicotine addiction, and menthol cigarette smokers tend to upregulate β2* nAChRs more than nonmenthol cigarette smokers.

A cross-sectional study on tobacco use and dependence among women: Does menthol matter?

open access: yesTobacco Induced Diseases, 2012
Background The question of whether mentholation of cigarettes enhances tobacco dependence has generated conflicting findings. Potential mediating factors in a putative relationship between menthol use and tobacco dependence may include race and gender ...

The effectiveness of orally applied L-menthol on exercise performance in the heat [PDF]

open access: yes, 2019
During exercise in the heat, increasing thermal load leads to thermo-behavioural adjustments in exercise performance, due to greater perceptual and physiological strain.

The distinctive role of menthol in pain and analgesia: Mechanisms, practices, and advances

open access: yesFrontiers in Molecular Neuroscience, 2022
Menthol is an important flavoring additive that triggers a cooling sensation. Under physiological condition, low to moderate concentrations of menthol activate transient receptor potential cation channel subfamily M member 8 (TRPM8) in the primary ...

The boundary cap: a source of neural crest stem cells that generate multiple sensory neuron subtypes [PDF]

open access: yes, 2005
The boundary cap (BC) is a transient neural crest-derived group of cells located at the dorsal root entry zone (DREZ) that have been shown to differentiate into sensory neurons and glia in vivo.
