Discrete 2D Material Programming for 3D Shaping and Morphogenesis‐Inspired 4D Bioprinting

open access: yesAdvanced Science, EarlyView.
Cell‐compatible discrete 2D material programming enables 2‐to‐3D shape transformation and morphogenesis‐inspired 4D bioprinting. By patterning cell‐supportive microdomains within a responsive hydrogel, the approach programs in‐plane growth to encode target metrics.

Phase Separation of TRIM21 Modulates PTPN14 Stability to Drive Flow‐Dependent Endothelial Activation and Atherogenesis

open access: yesAdvanced Science, EarlyView.
Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

A direct neurokinin B projection from the arcuate nucleus regulates magnocellular vasopressin cells of the supraoptic nucleus [PDF]

open access: yes, 2015
Central administration of neurokinin B (NKB) agonists stimulates immediate early gene expression in the hypothalamus and increases secretion of vasopressin from the posterior pituitary through a mechanism that depends on the activation of neurokinin ...

Minimal Transport Units Govern Oxygen‐Defect Stabilization and Transport for Lightweight Solid Electrolytes

open access: yesAdvanced Science, EarlyView.
Lightweight borate chemistry combined with minimal transport units provides a new pathway for designing lightweight oxide‐ion solid electrolytes. ABSTRACT Solid electrolytes are central to electrochemical energy technologies, including fuel cells, sensors, catalysis, membrane separation, and electrolyser.

Angiotensin II AT1A receptor mRNA expression is induced by estrogen–progesterone in dopaminergic neurons of the female rat arcuate nucleus

open access: yes, 1997
Brain angiotensin II (Ang II) inhibits pituitary prolactin release by an indirect mechanism requiring stimulation of dopamine formation and release. We report that [125I]Sar1-Ang II binding to AT1 receptors and AT1A receptor mRNA expression increase ...

Trithorax dependent changes in chromatin landscape at enhancer and promoter regions drive female puberty

open access: yesNature Communications, 2018
Before the onset of puberty, Polycomb proteins repress the expression of Kiss1 in KNDy neurons of the arcuate nucleus. Here, by CRISPR-Cas9-directed epigenome editing and RNAi, the authors show that coordinated action of Mll proteins at the Kiss1 ...

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries

open access: yesAdvanced Science, EarlyView.
A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving

Novel ontogenetic patterns of sexual differentiation in arcuate nucleus GHRH neurons revealed in GHRH-enhanced green fluorescent protein transgenic mice

open access: yes, 2010
GH secretion and growth rates are developmentally regulated and sexually dimorphic, but the neuroregulatory mechanisms between birth and puberty are unclear.

Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

open access: yesAdvanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Do tyrosine hydroxylase-immunoreactive neurons in the ventrolateral arcuate nucleus produce dopamine or only L-dopa?

open access: yes, 1988
Dopamine (DA) was early demonstrated in the arcuate nucleus by means of the formaldehyde-induced histofluorescence method. In the present study we have investigated the distribution of cell bodies in the arcuate nucleus with antisera against tyrosine ...
