Dopamine, the dopamine D2 receptor and pituitary tumours [PDF]

Clinical Endocrinology, 1991
Dopamine plays an important role in the hypothalamic-pituitary axis where its major effects are to inhibit pituitary hormone secretion and cell division. Chronic dopamine deficiency has been postulated as a cause of pituitary tumour formation and several lines of evidence exist to suggest that a functional deficiency may develop as a result of ...

Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

Advanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.

Pharmacological Evidence That Dopamine Inhibits the Cardioaccelerator Sympathetic Outflow via D2-Like Receptors in Pithed Rats

Journal of Pharmacological Sciences, 2013
It has been suggested that N,N-di-n-propyl-dopamine (dopamine analogue) decreased heart rate in rats through stimulation of dopamine receptors. Nevertheless, the role of prejunctional dopamine D1/2-like receptors or even α2-adrenoceptors to mediate ...

Dopamine-driven increase in IL-1β in myeloid cells is mediated by differential dopamine receptor expression and exacerbated by HIV

Journal of Neuroinflammation
The catecholamine neurotransmitter dopamine is classically known for regulation of central nervous system (CNS) functions such as reward, movement, and cognition. Increasing evidence also indicates that dopamine regulates critical functions in peripheral

Keratin–Melanin Complexation Enables Robust, Delamination‐Resistant Feather‐Inspired Structural Color Coatings for Flexible and Curved Substrates

Advanced Materials Interfaces, EarlyView.
Providing mechanically robust structural color coating technology inspired by cooperative interactions in nature. The spatial arrangement of melanin particles within the keratin matrix generates angle‐independent structural colors. Diverse functional groups in keratin and melanin contribute to interparticle and substrate adhesion, resulting in the ...
