Delayed rectifier K currents in NF1 Schwann cells
Neurobiology of Disease, 2003 K+ (K) currents are related to the proliferation of many cell types and have a relationship to second messenger pathways implicated in regulation of the cell cycle in development and certain disease states.

, 2018 We use deep \textit{Hubble Space Telescope} spectroscopy to constrain the metallicities and (\editone{light-weighted}) ages of massive ($\log M_\ast/M_\odot\gtrsim10$) galaxies selected to have quiescent stellar populations at $1 ...

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells
Advanced Science, EarlyView.The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...

Pressurization of cryogens: A review of current technology and its applicability to low-gravity conditions [PDF]
A review of technology, history, and current status for pressurized expulsion of cryogenic tankage is presented. Use of tank pressurization to expel cryogenic fluids will continue to be studied for future spacecraft applications over a range of operating

Advanced Science, EarlyView.In this study, we constructed a nanoparticle that was CD4 antibody‐mediated targeted, Fut7‐expressing plasmid‐loaded cationic liposome, namely CD4‐LDP‐Fut7. Upregulation of Fut7 expression in Tregs by using CD4‐LDP‐Fut7 can increase Treg homing to the intestine, thereby facilitating repair of the intestinal epithelial barrier and inhibiting ...

Gm-Realization of Controlled-Gain Current Follower Transconductance Amplifier
The Scientific World Journal, 2013 This paper describes the conception of the current follower transconductance amplifier (CFTA) with electronically and linearly current tunable. The newly modified element is realized based on the use of transconductance cells (Gms) as core circuits.

In situ structures of the segmented genome and RNA polymerase complex inside a dsRNA virus. [PDF]
, 2015 Viruses in the Reoviridae, like the triple-shelled human rotavirus and the single-shelled insect cytoplasmic polyhedrosis virus (CPV), all package a genome of segmented double-stranded RNAs (dsRNAs) inside the viral capsid and carry out endogenous ...

Advanced Science, EarlyView.By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Advanced Science, EarlyView.Normal bladders exhibit quiescent fibroblasts/macrophages, whereas neurogenic bladders show acute‐phase Itga8⁺ fibroblast expansion driven by Trem2⁺ macrophage‐secreted Fn1, which activates FAK/RhoA/ROCK signaling, promotes cytoskeletal remodeling, and upregulates pro‐fibrotic genes.
