The Effects of Ligand Substituents on the Character of Zn-Coordination in Zeolitic Imidazolate Frameworks [PDF]
arXiv, 2023 Due to their favorable properties and high porosity, zeolitic imidazolate frameworks (ZIFs) have recently received much limelight for key technologies such as energy storage, optoelectronics, sensorics, and catalysis. Despite the widespread interest in these materials, fundamental questions regarding the zinc coordination environment remain poorly ...

Colonic Fluid and Electrolyte Transport 2022: An Update
Cells, 2022 Colonic epithelial cells are responsible for maintaining a delicate balance between luminal secretion and the absorption of fluids and ions. This review aims to discuss and update the model of colonic electrolyte secretion and absorption via the cystic ...

Intestinal gluconeogenesis and glucose transport according to body fuel availability in rats [PDF]
J Physiol 566 (15/07/2005) 575-86, 2007 Intestinal hexose absorption and gluconeogenesis have been studied in relation to refeeding after two different fasting phases: a long period of protein sparing during which energy expenditure is derived from lipid oxidation (phase II), and a later phase characterized by a rise in plasma corticosterone triggering protein catabolism (phase III).

A Systemic Receptor Network Triggered by Human cytomegalovirus Entry [PDF]
Advances in Virology Volume 2011 (2011), Article ID 262080, 11
pages, 2010 Virus entry is a multistep process that triggers a variety of cellular pathways interconnecting into a complex network, yet the molecular complexity of this network remains largely unsolved. Here, by employing systems biology approach, we reveal a systemic virus-entry network initiated by human cytomegalovirus (HCMV), a widespread opportunistic ...

Advanced Science, EarlyView.CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced

Sites of Regulated Phosphorylation that Control K-Cl Cotransporter Activity [PDF]
Cell, 2009 Modulation of intracellular chloride concentration ([Cl(-)](i)) plays a fundamental role in cell volume regulation and neuronal response to GABA. Cl(-) exit via K-Cl cotransporters (KCCs) is a major determinant of [Cl(-)](I); however, mechanisms governing KCC activities are poorly understood.

Advanced Science, EarlyView.New research reveals that oxytocin signaling during the early postnatal period is critical for regulating brain development and social behavior. Selectively suppressing oxytocin neurons by chemogenetic method shows that early—but not late—disruption leads to autism‐like behaviors.

Distinct magnetic regimes through site-selective atom substitution in the frustrated quantum antiferromagnet Cs$_2$CuCl$_{4-x}$Br$_x$ [PDF]
, 2010 We report on a systematic study of the magnetic properties on single crystals of the solid solution Cs$_2$CuCl$_{4-x}$Br$_x$ (0 $\leq$ x $\leq$ 4), which include the two known end-member compounds Cs$_2$CuCl$_4$ and Cs$_2$CuBr$_4$, classified as quasi-two-dimensional quantum antiferromagnets with different degrees of magnetic frustration.
