Condensation of Diacetyl with Alkyl Amines: Synthesis and Reactivity of p-Iminobenzoquinones and p-Diiminobenzoquinones

open access: yesMolecules, 2015
Condensation reactions between diacetyl and α-branched primary alkylamines under mild and neutral conditions provided a mixture of 2,5-dimethylbenzoquinone(alkylimines), 2,5-dimethylbenzoquinone(bis-alkyldiimines), and N,N′-dialkyl-2,5-dimethylbenzene-1 ...

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

open access: yesSmall, EarlyView.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

Social media use, smoking expectancies, and nicotine experimentation in early adolescents: A prospective cohort study

open access: yesThe American Journal on Addictions, EarlyView.
Abstract Background and Objectives Social media exposure may influence early nicotine experimentation, a behavior linked to later nicotine dependence and health risks. Few studies have examined the role of smoking expectancies (i.e., beliefs about the anticipated positive or negative effects of nicotine) as a pathway underlying this association ...

Higher sensitivity to ouabain‐induced toxicity in human induced pluripotent stem cell‐derived cardiomyocytes than human adult heart tissue despite similar Na+/K+‐ATPase pump current amplitudes

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Human induced pluripotent stem cell‐derived cardiomyocytes (hiPSC‐CM) have gained interest as a pharmacological model but their immaturity leads to uncertainty regarding translation. We studied the key player in maintaining ionic homeostasis, the Na+/K+‐ATPase (NKA), in hiPSC‐CM.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...
