Arbuscular mycorrhizal type increases the negative feedback of soil microbial biomass to nitrogen deposition.

Soil microbes are crucial for ecosystem health and functioning, playing key roles in decomposing organic matter, nutrient cycling, and carbon sequestration. Mycorrhizal fungi, a vital group of soil microbes, establish symbiotic relationships with plant roots, enhancing plant nutrient uptake and improving soil structure. Globally nitrogen (N) enrichment is recognized as a significant regulator of soil microbial communities.

Mycorrhizal types determined the response of yield of woody bioenergy crops to environmental factors.

Meeting the demand for energy solely through fossil fuels has posed challenges. To mitigate the risk of energy shortage, woody bioenergy crops as a renewable energy feedstock have been the subject of many researchers. Also, mycorrhizas play an important role in crop productivity and inevitably affect the biomass yield of woody bioenergy crops.

Mycorrhizal status regulates plant phenological mismatch caused by warming.

Mycorrhiza is an important functional feature of plants, which plays a vital role in regulating plant phenology in response to environmental changes. However, the effect of mycorrhiza on plant phenological asymmetry in response to climate changes is still rarely reported. Based on a global database of mycorrhizal statuses (obligately mycorrhizal, OM and facultatively mycorrhizal, FM) and phenology, we demonstrated that mycorrhizas reduce the phenological mismatches between above- and below-ground plant responses to climate warming under OM status.

Diagnostic outcomes of radial endobronchial ultrasound bronchoscopy guided by manual navigation in the evaluation of peripheral pulmonary lesions: An observational study.

Background And Aims: Manual navigation (MN), drawing a bronchoscopic road map simply by looking at the consecutive computed tomography (CT), is feasible and economical. However, scant data about the use of MN in radial endobronchial ultrasound (r-EBUS) bronchoscopy have been documented till now. We aimed to evaluate the diagnostic performance of r-EBUS bronchoscopy guided by MN for diagnosing peripheral pulmonary lesions (PPLs) and to determine clinical factors affecting the diagnostic yield.

Iodine-125 seed brachytherapy combined with pembrolizumab for advanced non-small-cell lung cancer after failure of first-line chemotherapy: A report of two cases and literature review.

Although immunotherapy regimens for advanced non-small-cell lung cancer (NSCLC) improve survival in selected sub-populations, their efficacy remains far from ideal due to underlying resistance; therefore, multimodal combination strategies are needed to optimize their efficacy. In our report, two patients with advanced NSCLC with negative targetable mutations, who had failed first-line chemotherapy were treated with combined therapy of computed tomography (CT)-guided percutaneous iodine-125 seed implantation and pembrolizumab. After combination treatment, both patients achieved partial response (PR), and sustained a long progression-free survival (PFS) without obvious therapy-related adverse reactions.

The Variations of Leaf δC and Its Response to Environmental Changes of Arbuscular and Ectomycorrhizal Plants Depend on Life Forms.

Arbuscular mycorrhiza (AM) and ectomycorrhiza (ECM) are the two most common mycorrhizal types and are paid the most attention to, playing a vital common but differentiated function in terrestrial ecosystems. The leaf carbon isotope ratio (δC) is an important factor in understanding the relationship between plants and the environment. In this study, a new database was established on leaf δC between AM and ECM plants based on the published data set of leaf δC in China's C terrestrial plants, which involved 1163 observations.

Solution anode glow discharge optical emission spectrometry: Volatile hydride introduction from the gas jet nozzle cathode for ultrasensitive determination of lead.

An ultrasensitive method for the determination of Pb was developed by coupling solution anode glow discharge-optical emission spectrometry (SAGD-OES) with hydride generation (HG). Compared to solution cathode glow discharge, the introduction of analytes yielded via HG from the discharge cathode into the microplasma was demonstrated to be easily performed by SAGD in which the gas jet nozzle served as cathode and further enhanced sensitivity for Pb determination was achieved. The susceptibility of SAGD-OES to the matrix-induced interferences in the analysis of real samples was significantly improved owing to the coupling of HG.

MitoK channels promote the proliferation of hypoxic human pulmonary artery smooth muscle cells via the ROS/HIF/miR-210/ISCU signaling pathway.

Previous results have indicated that mitochondrial ATP-sensitive potassium (mitoK) channels are associated with the hypoxic proliferation of pulmonary artery smooth muscle cells (PASMCs). However, the mechanism underlying the promotive effects of mitoK channels on cell proliferation in response to hypoxia remains unknown. mitoK channel opening results in a collapse of mitochondrial membrane potential and generation of mitochondrial reactive oxygen species (ROS).

A case of tracheobronchitis in a patient with chronic obstructive pulmonary disease.

Aspergillus tracheobronchitis (AT) is a unique form of invasive pulmonary aspergillosis, which is commonly found in patients with impaired immunity. Early-stage AT presents in a nonspecific way, both clinically and radiographically, thereby delaying diagnosis and resulting in a high mortality. Owing to impaired mucociliary clearance, previous nonfungal infections, and administration of corticosteroids, among other aspects, patients with chronic obstructive pulmonary disease (COPD) are predisposed to AT, although they are mostly immunocompetent.

MitoKATP regulating HIF/miR210/ISCU signaling axis and formation of a positive feedback loop in chronic hypoxia-induced PAH rat model.

In the present study, we studied the mechanism of mitochondrial ATP-sensitive potassium (mitoKATP) channels regulating hypoxia-inducible factor (HIF)-1α/microRNA (miR)-210/mitochondrial iron-sulfur protein integrin (ISCU) signaling axis and forming a positive feedback loop in chronic hypoxia-induced pulmonary arterial hypertension (PAH) by using animal model. Two hundred healthy adult SPF Sprague-Dawley rats were randomly divided into five groups: Control, a mimic miR-210 agent (mimic-210) intervention, a miR-210 inhibitor (anti-210) intervention, a chronic PAH and an anti-210 intervention PAH groups, with 40 rats in each group. After the chronic PAH rat model was successfully established, the rats were intervened with mimic-210 and anti-210.
