Photoactivation‐Enabled Tunable Room‐Temperature Phosphorescence and Thermally Activated Delayed Fluorescence in Crystalline Materials

Advanced Science, EarlyView.
This work is the first to demonstrate the regulation of photoactivated room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) in crystalline materials without any pretreatment. Furthermore, we reveal the underlying mechanisms by uncovering the role of host‐guest energy level alignment, exciton lifetime, crystallinity,

Single‐Molecule Imaging of Endogenous RNA Using a Miniaturized and Circularly Permuted CRISPR‐Cas13 Degron‐Masking System CDegSR

Advanced Science, EarlyView.
CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

Estimating the change in pleural pressure using the change in central venous pressure in various clinical scenarios: a pig model study

Intensive Care Medicine Experimental
Background We have previously reported a simple correction method for estimating pleural pressure (Ppl) using central venous pressure (CVP). However, it remains unclear whether this method is applicable to patients with varying levels of intravascular ...

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

Advanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Spatial variability of compound-specific δD at the field scale: A case study from miliacin in broomcorn millet (Panicum miliaceum). [PDF]

, 2011
International audienceThe hydrogen isotopic composition (δD) of individual compounds preserved in lake sediments has been proposed as a proxy of the hydrological conditions that prevailed at time of their synthesis. Numerous parameters are susceptible of

亚热带典型植物水分利用来源变化的水稳定同位素分析

Shuitu Baochi Xuebao, 2020
旨在揭示亚热带湿润地区不同植物水分利用来源和了解区域森林系统水文循环过程，以长沙地区典型常绿植物樟树、刺杉和野茶花为研究对象，利用稳定同位素技术及Iso-source混合模型定量分析不同植物水分利用特征及其对降水的响应。结果表明：在2018年9月至2019年2月的观测期内，0—10 cm土壤水中δD与降水中δD的变化趋势基本-致，均随时间变化逐渐偏正。随深度的增加，土壤水中δD受降水影响的程度逐渐减小并趋于稳定。在9—11月，3种植物对降水响应程度低，植物茎杆水中δD并未随降水中δD表现出明显偏正的趋势，

Glucocorticoid Receptor Signaling in Myeloid Cells Orchestrates Inflammation Resolution and Muscle Repair

Advanced Science, EarlyView.
Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...

Ground State Solutions for General Choquard Equation With the Riesz Fractional Laplacian

Advances in Mathematical Physics
In this work, we study the existence of a nonzero solution for the following nonlinear general Choquard equation (CE): −Δν+ν=−ΔD−α2 ∗ Fνfν,in ℝN, where N≥3, F represents the primitive function of f,  f∈CR;R is a function that fulfils the general ...

Beyond Biomimetics: Pathology‐Informed Engineering Rescues Reconstituted HDL From Inflammatory Dysfunction for Sepsis Immunotherapy

Advanced Science, EarlyView.
A pathology‐informed engineering strategy rescues reconstituted HDL from inflammatory dysfunction in sepsis. By integrating a ceria nanozyme‐celastrol coordination complex, the platform preserves HDL structure and endotoxin handling, sustains hierarchical intracellular delivery, and enhances immunoregulation across pathological models, translating ...
