Directional DBS has the potential to minimize stimulation-induced side effects and maximize clinical benefits. Many new directional leads, stimulation patterns and programming strategies have been developed in recent years.

Defects vibrations engineering for enhancing interfacial thermal transport in polymer composites.

To push upper boundaries of thermal conductivity in polymer composites, understanding of thermal transport mechanisms is crucial. Despite extensive simulations, systematic experimental investigation on thermal transport in polymer composites is limited. To better understand thermal transport processes, we design polymer composites with perfect fillers (graphite) and defective fillers (graphite oxide), using polyvinyl alcohol (PVA) as a matrix model.

Histone deacetylase SlHDA7 impacts fruit ripening and shelf life in tomato.

Fruit ripening depends on the accurate control of ripening-related genes expression, with histone deacetylases (HDACs) playing crucial roles in transcriptional regulation. However, the functions of HDACs in fruit maturation remain largely unexplored. Here, we show that SlHDA7 acts as a suppressor of fruit ripening and functions as an H4ac HDAC in tomato.

LINC00461 promotes bladder cancer cells EMT through miR-518b/HNRNPUL1 axis.

Bladder cancer (BC) is a prevalent type of tumor in the urinary system, and it has been discovered that long non-coding RNA (lncRNA) plays a significant role in its occurrence and development. However, thus far, no reports have been published on the involvement of LINC00461 in BC. Here, we found that LINC00461 levels were upregulated in BC tissues and cell lines.

Mesoporous metal-organic framework NH-MIL-101(Cr) as an efficient photocatalyst for the epoxidation of styrene.

Oxidation of styrene is a key reaction in the synthesis of pharmaceuticals and fine chemicals, and therefore oxidizing styrene with selective, efficient, and recyclable heterogeneous catalysts is significant from an environmental and economic standpoint. In this study, we report the transition Cr-based metal-organic framework [NH-MIL-101(Cr)] as a heterogeneous photocatalyst, which efficiently promotes styrene epoxidation using HO as a green oxidant, achieving high conversion efficiency (98%) and excellent selectivity (82%) under ambient conditions. Radical detection and quenching experiments reveal that the superoxide radical anion (O˙) acts as an active oxygen species, selectively promoting the oxidation of styrene to its oxidized form.

On the Application of Artificial Intelligence/Machine Learning (AI/ML) in Late-Stage Clinical Development.

Enhancing the high-temperature energy storage properties of PEI dielectrics by constructing trap-rich covalently cross-linked networks POSS-functionalized BNNS.

Polymer films are ideal dielectric materials for energy storage capacitors due to their light weight and flexibility, but lower energy density and poor heat resistance greatly limit their application in high-temperature energy storage. Unlike the traditional method of solely adding wide-bandgap inorganic fillers to enhance energy density, in this study we constructed trap-rich hybrid covalently cross-linked networks in polyetherimide (PEI) reactive polyhedral oligomeric silsesquioxane (POSS)-functionalized boron nitride nanosheets (BNNS@POSS), which not only serve as interfacial layers for dielectric transitions and insulating barriers but also create deeper traps and higher energy barriers in the region of cross-linked chains. This strategy based on the co-modulation of interfaces and traps achieved the compatibility of high polarization and high breakdown strength and improved energy storage performance.

Squalene epoxidase promotes the chemoresistance of colorectal cancer via (S)-2,3-epoxysqualene-activated NF-κB.

Background: While de novo cholesterol biosynthesis plays a crucial role in chemotherapy resistance of colorectal cancer (CRC), the underlying molecular mechanism remains poorly understood.

Methods: We conducted cell proliferation assays on CRC cells with or without depletion of squalene epoxidase (SQLE), with or without 5-fluorouracil (5-FU) treatment. Additionally, a xenograft mouse model was utilized to explore the impact of SQLE on the chemosensitivity of CRC to 5-FU.

NET-targeted nanoparticles for antithrombotic therapy in pregnancy.

Pulmonary embolism caused by deep vein thrombosis (DVT) is a major contributor to maternal morbidity and mortality. There is still an unmet need for safe and effective treatment options for DVT during pregnancy. Recent research has shown that neutrophil extracellular trap (NET) formation plays a very vital role in thrombosis.

Platelet membrane encapsulated curcumin nanomaterial-mediated specific thrombolysis and anti-thrombotic treatment among pregnant women.

The current treatment for venous thrombosis during pregnancy is ineffective, primarily, due to the unique physiology of pregnant women. Most clinical medications have fetal side effects when they circulate in the body. We first synthesized nanomaterials (Cur-PFP@PC) using poly lactic-co-glycolic acid (PLGA) as the base material, with curcumin (Cur) and perfluoropentane (PFP) as core components.

Natural products, originating from traditional medicine, represent a significant therapeutic avenue and primary source for new drug development.

Histone H3K27 demethylase SlJMJ3 modulates fruit ripening in tomato.

The histone lysine (K) demethylase 4 (KDM4/JHDM3) subfamily of jumonji domain-containing demethylases (JMJs) has been implicated in various aspects of plant development. However, their involvement in regulating the ripening of fleshy fruits remains unclear. In this study, we identified SlJMJ3, a member of the KDM4/JHDM3 family, as an H3K27me3 demethylase in tomato (Solanum lycopersicum) that plays an important role in fruit ripening regulation.

Enabling Rapid and Stable Sodium Storage via a P2-Type Layered Cathode with High-Voltage Zero-Phase Transition Behavior.

Currently, a major target in the development of Na-ion batteries is the concurrent attainment of high-rate capacity and long cycling stability. Herein, an advanced Na-ion battery with high-rate capability and long cycle stability based on Li/Ti co-doped P2-type NaMnNiO, a host material with high-voltage zero-phase transition behavior and fast Na migration/conductivity during dynamic de-embedding process, is constructed. Experimental results and theoretical calculations reveal that the two-element doping strategy promotes a mutually reinforcing effect, which greatly facilitates the transfer capability of Na.

ATP homeostasis and signaling in plants.

ATP is the primary form of energy for plants, and a shortage of cellular ATP is generally acknowledged to pose a threat to plant growth and development, stress resistance, and crop quality. The overall metabolic processes that contribute to the ATP pool, from production, dissipation, and transport to elimination, have been studied extensively. Considerable evidence has revealed that in addition to its role in energy supply, ATP also acts as a regulatory signaling molecule to activate global metabolic responses.

In Vivo Transcranial Acoustoelectric Brain Imaging of Different Deep Brain Stimulation Currents.

Deep brain stimulation (DBS) is an effective treatment for neurologic disease and its clinical effect is highly dependent on the DBS leads localization and current stimulating state. However, standard human brain imaging modalities could not provide direct feedback on DBS currents spatial distribution and dynamic changes. Acoustoelectric brain imaging (AEBI) is an emerging neuroimaging method that can directly map current density distribution.

Marginal versus conditional rate estimation for count and recurrent event data with an estimand framework.

Count and recurrent event endpoints are common key efficacy endpoints in clinical research. For example, in clinical research of pulmonary diseases such as chronic obstructive pulmonary disease (COPD) or asthma, the reduction of the occurrence of a recurrent event, pulmonary exacerbation (PEx) caused by acute respiratory symptoms, is often used to measure the treatment effect. The occurrence of PEx is often analyzed with nonlinear models, such as Poisson regression or Negative Binomial regression.

We recruited 1607 fertile men and their partners from 2014 to 2016 and collected semen samples to detect sperm DNA methylation.

WUSCHEL-related homeobox transcription factor SlWOX13 regulates tomato fruit ripening.

Fruit ripening is a complex, genetically programmed process involving the action of critical transcription factors (TFs). Despite the established importance of WUSCHEL-related homeobox (WOX) TFs in plant development, the involvement of WOX and its underlying mechanism in the regulation of fruit ripening remain unclear. Here, we demonstrate that SlWOX13 regulates fruit ripening in tomato (Solanum lycopersicum).
