Advances in the diagnosis and management of post-percutaneous coronary intervention coronary microvascular dysfunction: Insights into pathophysiology and metabolic risk interactions.

Percutaneous coronary intervention (PCI), as an essential treatment for coronary artery disease, has significantly improved the prognosis of patients with large coronary artery lesions. However, some patients continue to experience myocardial ischemic symptoms post-procedure, largely due to coronary microvascular dysfunction (CMD). The pathophysiological mechanisms of CMD are complex and involve endothelial dysfunction, microvascular remodeling, reperfusion injury, and metabolic abnormalities.

Differential responses of root and leaf-associated microbiota to continuous monocultures.

Continuous monocultures alter the composition and function of root-associated microbiota, and thus compromise crop health and productivity. In comparison, little is known about how leaf-associated microbiota respond to continuous monocultures. Here, we profiled root and leaf-associated microbiota of peanut plants under monocropping and rotation conditions.

Apolipoprotein E dysfunction in Alzheimer's disease: a study on miRNA regulation, glial markers, and amyloid pathology.

Introduction: Apolipoprotein E (ApoE) plays a crucial role in lipid homeostasis, predominantly expressed in astrocytes and to a lesser extent in microglia within the central nervous system (CNS). While the allele is the strongest genetic risk factor for late-onset Alzheimer's disease (AD), its precise role in AD pathogenesis remains elusive. -knockout (-ko) mice, mice expressing human , and human carriers exhibit similar deficits in lipid metabolism, cognitive and behavioral functions, and neurodegeneration.

3-Dimensional morphological characterization of neuroretinal microglia in Alzheimer's disease via machine learning.

Alzheimer's Disease (AD) is a debilitating neurodegenerative disease that affects 47.5 million people worldwide. AD is characterised by the formation of plaques containing extracellular amyloid-β (Aβ) and neurofibrillary tangles composed of hyper-phosphorylated tau proteins (pTau).

Highly electroactive mixed-valence-MoO as an electrochemical sensing for effective detection of p-nitrophenol based on the synergistic effect of valence change and oxygen vacancy.

Transition metal oxides (TMOs) can effectively improve the performance of electrochemical detection due to their unique electronic structure and redox properties. However, the lack of reproducibility and the electrical activity of TMOs prepared from conventional preparation methods limit their further development. In this work, amorphous MoO with reductive Mo(V) was successfully synthesized by one-step electrodeposition, and it has excellent detection performance for p-nitrophenol (PNP).

Sensitive detection of Hg(II) on MoS/NiS based on interfacial engineering to accelerate the Ni/Ni cycle: Identification the role of atomic-level heterojunction-induced electron transfer in electroanalysis.

The valence change of transition metal ions in nanomaterials can highly enhance the electrochemical detection performance toward heavy metal ions (HMIs), and how to further promote the valence change calls enormous concerns in electroanalysis. In this work, an interfacial engineering that combing the MoS and NiS together to form the MoS/NiS complex is proposed. The density functional theory (DFT) results reveals that the novel atomic-level heterojunction between MoS and NiS will build an internal electric field (IEF), which leads to an enhanced conductivity and valence change behavior of Ni atoms in MoS/NiS complex, resulting in a superior detection performance.

Chemical Synthesis, Herbicidal Activity, Crop Safety, and Molecular Basis of -Fluoroalkoxy Substituted Sulfonylureas as Novel Acetohydroxyacid Synthase Inhibitors.

Root Endophyte-Manipulated Alteration in Rhizodeposits Stimulates in the Rhizosphere to Enhance Drought Resistance in Peanut.

Drought dramatically affects plant growth and yield. A previous study indicated that endophytic fungus can improve the drought resistance of peanuts, which is related with the root arbuscular mycorrhizal fungi (AMF) community; however, how root endophytes mediate AMF assembly to affect plant drought resistance remains unclear. Here, we explored the mechanism by which endophytic fungus recruits AMF symbiotic partners via rhizodeposits to improve host drought resistance.

High efficiency Hg(II) electrochemical detection based on the number of defect engineering on MoS: Insight in synergistic action of sulfur vacancies and undercoordinated Mo.

Defects on nanomaterials can effectively enhance the performance of electrochemical detection, but an excessive number of defects may have an adverse effect. In this study, MoS nanosheets were synthesized using a hydrothermal synthesis method. By controlling the calcination temperature, MoS-7H, calcined at 700 °C under H/Ar, exhibited an optimal ratio of "point" defects to "plane" defects, resulting in excellent detection performance for mercury ions (Hg(II)).

Electrochemical stereoselective synthesis of polysubstituted 1,4-dicarbonyl -alkenes three-component coupling of sulfoxonium ylides and alkynes with water.

The first straightforward strategy for the synthesis of 1,4-dicarbonyl -alkenes has been developed an electrochemical cross-coupling reaction of sulfoxonium ylides and alkynes with water. The metal-free protocol showed an easy-to-handle nature, good functional group tolerance, and high -stereoselectivity, which is rare in previous cases. The proposed reaction mechanism was convincingly established by carrying out a series of control experiments, cyclic voltammetry experiments, and density functional theory (DFT) studies.

Depletion of protective microbiota promotes the incidence of fruit disease.

Plant-associated microbiomes play important roles in plant health and productivity. However, despite fruits being directly linked to plant productivity, little is known about the microbiomes of fruits and their potential association with fruit health. Here, by integrating 16S rRNA gene, ITS high-throughput sequencing data, and microbiological culturable approaches, we reported that roots and fruits (pods) of peanut, a typical plant that bears fruits underground, recruit different bacterial and fungal communities independently of cropping conditions and that the incidence of pod disease under monocropping conditions is attributed to the depletion of Bacillus genus and enrichment of Aspergillus genus in geocarposphere.

Excited-Multimer Mediated Supramolecular Upconversion on Multicomponent Lanthanide-Organic Assemblies.

Upconversion (UC) is a fascinating anti-Stokes-like optical process with promising applications in diverse fields. However, known UC mechanisms are mainly based on direct energy transfer between metal ions, which constrains the designability and tunability of the structures and properties. Here, we synthesize two types of LnL-type (Ln for lanthanide ion; L for organic ligand L or L) lanthanide-organic complexes with assembly induced excited-multimer states.

Role of macrophages in pulmonary arterial hypertension.

Pulmonary arterial hypertension (PAH) is a severe cardiopulmonary vascular disease characterized by progressive pulmonary artery pressure elevation, increased pulmonary vascular resistance and ultimately right heart failure. Studies have demonstrated the involvement of multiple immune cells in the development of PAH in patients with PAH and in experimental PAH. Among them, macrophages, as the predominant inflammatory cells infiltrating around PAH lesions, play a crucial role in exacerbating pulmonary vascular remodeling in PAH.

Prediction of OH-Initiated and NO-Initiated Transformation Products of Polycyclic Aromatic Hydrocarbons by Electronic Structure Approaches.

The abiotic reaction products of polycyclic aromatic hydrocarbons (PAHs) with hydroxyl radicals (OH) and nitrate radicals (NO) are nitro-, oxygen-, and hydroxyl-containing PAHs (NPAHs, OPAHs, and OHPAHs). Four methods of the highest occupied molecular orbital (HOMO), Fukui function (FF), dual descriptor (DD), and population of π electrons (PP-π) are selected to predict the chemical reactivity of PAHs attacked by OH and NO in this study. The predicted OH-initiated and NO-initiated transformation products are compared with the main PAH transformation products (PAH-TPs) observed in the laboratory.

A new photodynamic therapy photosensitizer (p1) promotes apoptosis of keloid fibroblasts by targeting caspase-8.

Photodynamic therapy (PDT) is a new therapy for treating cancer with less toxicity, high selectivity, good cooperativity, and repetitive usability.
