Resource Segmentation: A New Dimension of the Segmentation Hypothesis in Drought Adaptive Strategies and Its Links to Tree Growth Performance.

The segmentation hypothesis, a framework for understanding plant drought adaptive strategy, has long been based on hydraulic resistance and vulnerability. Storage of water and carbohydrate resources is another critical function and shapes plant drought adaption and fitness together with hydraulic efficiency and vulnerability. However, patterns and implications of the interdependency of stored water and carbohydrate resources in the context of the segmentation hypothesis are poorly understood.

TLR7/8/9 agonists and low-dose cisplatin synergistically promotes tertiary lymphatic structure formation and antitumor immunity.

In situ vaccination (ISV) triggers antitumor immune responses using the patient's own cancer antigens, yet limited neoantigen release hampers its efficacy. Our novel combination therapy involves low-dose local cisplatin followed by ISV with a TLR7/8/9 agonist formulation (CR108), in which CR108 boosts and sustains the antitumor responses induced by the cisplatin-released neoantigens. In mouse models, the cisplatin+CR108 combination significantly outperformed cisplatin or CR108 alone in abrogating established 4T1 and B16 tumors.

Purpose To assess the response of parathyroid hormone (PTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels to US-guided parathyroid MWA and RFA and the safety of these treatments in participants with SHPT. Materials and Methods This prospective multicenter cohort study, conducted from September 2017 to March 2022, included participants with SHPT.

Improving electron injection of organic light-emitting transistors interface layer design.

Ambipolar transport is crucial for constructing high performance organic light-emitting transistors (OLETs), but the ambipolar feature is usually not exhibited due to ineffective electron injection especially in symmetric device geometry. Herein, we show that electron injection could be greatly enhanced through the judicious design of an organic interface layer of 3,7-di(2-naphthyl)dibenzothiophene ,-dioxide (DNaDBSO) which shows an interfacial dipole effect upon contact with a metal electrode, especially an Au electrode. When incorporating a DNaDBSO film beneath Au electrodes, the electron injection and mobility were significantly enhanced in 2,6-diphenylanthracene-based OLETs, and thus ambipolar transport (maxh: 2.

Macrophage LRRK2 hyperactivity impairs autophagy and induces Paneth cell dysfunction.

polymorphisms (G2019S/N2081D) that increase susceptibility to Parkinson's disease and Crohn's disease (CD) lead to LRRK2 kinase hyperactivity and suppress autophagy. This connection suggests that LRRK2 kinase inhibition, a therapeutic strategy being explored for Parkinson's disease, may also benefit patients with CD. Paneth cell homeostasis is tightly regulated by autophagy, and their dysfunction is a precursor to gut inflammation in CD.

Sodium Hydrosulfide Protects Rats from Hypobaric-Hypoxia-Induced Acute Lung Injury.

Hydrogen sulfide (HS), as a key gas signaling molecule, plays an important role in regulating various diseases, with appropriate concentrations providing antioxidative, anti-inflammatory, and anti-apoptotic effects. The specific role of HS in acute hypoxic injury remains to be clarified. This study focuses on the HS donor sodium hydrosulfide (NaHS) and explores its protective effects and mechanisms against acute hypoxic lung injury.

Toward a CRISPR-based mouse model of -deficient clear cell kidney cancer: Initial experience and lessons learned.

CRISPR is revolutionizing the ability to do somatic gene editing in mice for the purpose of creating new cancer models. Inactivation of the tumor suppressor gene is the signature initiating event in the most common form of kidney cancer, clear cell renal cell carcinoma (ccRCC). Such tumors are usually driven by the excessive HIF2 activity that arises when the gene product, pVHL, is defective.

The Vaginal Microbiome: Patient- versus Physician-Collected Microbial Swab: A Pilot Study.

The composition of the vaginal microbiota prior to an IVF/IVF-ICSI treatment can predict the chance of achieving a pregnancy. To improve clinical applicability and be more patient-friendly, the self-collection of vaginal samples would be preferable. However, the reliability of patient-collected samples compared to physician-collected samples remains unclear.

Preparation and in vitro evaluation of pH and glutathione dual-responsive drug delivery system based on sodium carboxymethyl cellulose.

Stimuli-responsive drug delivery systems based on sodium carboxymethyl cellulose (NaCMC) for drug release encounter inherent challenges. In this research, a novel pH and glutathione (GSH) dual-responsive system, CPT-S-S-NaCMC@ZIF-8/SP-PEG, was constructed. Firstly, the prodrug CPT-S-S-OH was synthesized and combined with NaCMC to form GSH-responsive micelles CPT-S-S-NaCMC, significantly enhancing the drug loading and grafting rates to 63.

Solidification/stabilization pre-treatment coupled with landfill disposal of heavy metals in MSWI fly ash in China: A systematic review.

The growth in municipal solid waste incineration (MSWI) has resulted in a substantial rise in the production of fly ash in China. It is anticipated that during the "14th Five-Year Plan", the accumulated amount of fly ash stocked and disposed of at landfills will surpass 100 million tons. With the development of the economy and the implementation of garbage classification relevant policies, the pollution characteristics of heavy metal change in spatiotemporal distribution.

Co-targeting SOS1 enhances the antitumor effects of KRAS inhibitors by addressing intrinsic and acquired resistance.

Combination approaches are needed to strengthen and extend the clinical response to KRAS inhibitors (KRASi). Here, we assessed the antitumor responses of KRAS mutant lung and colorectal cancer models to combination treatment with a SOS1 inhibitor (SOS1i), BI-3406, plus the KRAS inhibitor, adagrasib. We found that responses to BI-3406 plus adagrasib were stronger than to adagrasib alone, comparable to adagrasib with SHP2 (SHP2i) or EGFR inhibitors and correlated with stronger suppression of RAS-MAPK signaling.

Topographic Clinical Insights From Deep Learning-Based Geographic Atrophy Progression Prediction.

Purpose: To explore the contributions of fundus autofluorescence (FAF) topographic imaging features to the performance of convolutional neural network-based deep learning (DL) algorithms in predicting geographic atrophy (GA) growth rate.

Methods: Retrospective study with data from study eyes from three clinical trials (NCT02247479, NCT02247531, NCT02479386) in GA. The algorithm was initially trained with full FAF images, and its performance was considered benchmark.

Combination Nanomedicine Strategy for Preventing High-Risk Corneal Transplantation Rejection.

High-risk (HR) corneal transplantation presents a formidable challenge, with over 50% of grafts experiencing rejection despite intensive postoperative care involving frequent topical eyedrop administration up to every 2 h, gradually tapering over 6-12 months, and ongoing maintenance dosing. While clinical evidence underscores the potential benefits of inhibiting postoperative angiogenesis, effective antiangiogenesis therapy remains elusive in this context. Here, we engineered controlled-release nanomedicine formulations comprising immunosuppressants (nanoparticles) and antiangiogenesis drugs (nanowafer) and demonstrated that these formulations can prevent HR corneal transplantation rejection for at least 6 months in a clinically relevant rat model.

Synergistic solidification and mechanism research of electrolytic manganese residue and coal fly ash based on C-A-S-H gel material.

Electrolytic manganese residue (EMR) is known for high concentrations of Mn, NH, and heavy metals. Failure to undergo benign treatment and landfill disposal would undeniably lead to negative impacts on the quality of the surrounding ecological environment. This study sought to mitigate the latent environmental risks associated with EMR using a cooperative solidification/stabilization (S/S) method involving coal fly ash (CFA).

Introduction: We investigated the effect of perivascular spaces (PVS) volume on speeded executive function (sEF), as mediated by white matter hyperintensities (WMH) volume and plasma glial fibrillary acidic protein (GFAP) in neurodegenerative diseases.

Methods: A mediation analysis was performed to assess the relationship between neuroimaging markers and plasma biomarkers on sEF in 333 participants clinically diagnosed with Alzheimer's disease/mild cognitive impairment, frontotemporal dementia, or cerebrovascular disease from the Ontario Neurodegenerative Disease Research Initiative.

Results: PVS was significantly associated with sEF (c = -0.

Construction and enhancement of built-in electric field for efficient oxygen evolution reaction.

The construction and regulation of built-in electric field (BIEF) are considered effective strategies for enhancing the oxygen evolution reaction (OER) performance of transition metal-based electrocatalysts. Herein, we present a strategy to regulate the electronic structure of nickel-iron layered double hydroxide (NiFe-LDH) by constructing and enhancing the BIEF induced by in-situ heterojunction transformation. This concept is demonstrated through the design and synthesis of AgS@S/NiFe-LDH (p-n heterojunction) and Ag@S/NiFe-LDH (Mott-Schottky heterojunction).

Dynamic Interchain Motion in 1D Tetrathiafulvalene-Based Coordination Polymers for Highly Sensitive Molecular Recognition.

The application of electrically conductive 1D coordination polymers (1D CPs) in nanoelectronic molecular recognition is theoretically promising yet rarely explored due to the challenges in their synthesis and optimization of electrical properties. In this regard, two tetrathiafulvalene-based 1D CPs, namely [Co(m-HTTFTB)(DMF)(HO)] (Co-m-TTFTB), and {[Ni(m-HTTFTB)(CHCHOH)(HO)]·(HO)} (Ni-m-TTFTB) are successfully constructed. The shorter S···S contacts between the [M(solvent)(m-HTTFTB)] chains contribute to a significant improvement in their electrical conductivities.
