Soil microbial community composition and nitrogen enrichment responses to the operation of electric power substation.

The surge in global energy demand mandates a significant expansion of electric power substations. Nevertheless, the ecological consequences of electric power substation operation, particularly concerning the electromagnetic field, on soil microbial communities and nitrogen enrichment remain unexplored. In this study, we collected soil samples from six distinct sites at varying distances from an electric power substation in Xintang village, southeastern China, and investigated the impacts of electromagnetic field on the microbial diversity and community structures employing metagenomic sequencing technique.

Metallic Copper-Based Dual-Enzyme Biomimetic Nanoplatform for Mild Photothermal Enhancement of Anticancer Catalytic Activity.

Chemodynamic therapy (CDT) is recognized as a promising cancer treatment. Recently, copper sulfide nanostructures have been extensively employed as Fenton-like reagents that catalyze the formation of acutely toxic hydroxyl radicals (·OH) from hydrogen peroxide (HO). However, CDT therapeutic potency is restricted by the tumor microenvironment (TME), such as insufficient amounts of hydrogen peroxide, excessive glutathione levels, etc.

Laser-activated nanoparticles for ultrasound/photoacoustic imaging-guided prostate cancer treatment.

Prostate cancer (PCa) is the most common malignant tumor in men. Prostate-specific membrane antigen (PSMA), which is overexpressed on the surface of Prostate cancer cells, may serve as a potential therapeutic target. Recently, image-guided and targeted therapy for prostate cancers has attracted much attention by using Prostate-specific membrane antigen targeting nanoparticle.

Sonosensitive Phase-Changeable Nanoparticle Mediated Enhanced Chemotherapy in Prostate Cancer by Low-Intensity Focused Ultrasound.

Prostate cancer (PCa) is one of the most common cancer types. Early detection of PC offers the best chance of successful treatment. A noninvasive, image-guided therapy mediated by targeted nanoparticles (NPs) has the potential to improve the efficacy and safety of cancer therapies.

Clinical efficacy of turtle shell decocted pills for endometriosis and their influence on cellular immunity.

Objective: To explore the therapeutic efficacy of the levonorgestrel-releasing intrauterine system combined with turtle shell decocted pills for endometriosis and their effect on cellular immune function.

Methods: Clinical data of 118 patients with endometriosis admitted to Taizhou First People's Hospital from January 2019 to January 2020 were retrospectively analyzed. The patients were assigned into a single-drug group (n=68) and a combined traditional Chinese medicine group (n=50) according to treatment methods.

Over-immunity mediated abnormal deposition of lignin arrests the normal enlargement of the root tubers of Rehmannia glutinosa under consecutive monoculture stress.

The rapid accumulation of lignin in the cell wall is one of important immune defense mechanism in response to adversity stress in plants. In this study, we found that the enlargement of the root tubers of Rehmannia glutinosa (R. glutinosa) is arrested under consecutive monoculture stress, and this process is accompanied by abnormal accumulation of lignin.

Integrated Analysis of Transcriptomic and Proteomics Data Reveals the Induction Effects of Rotenoid Biosynthesis of Caused by UV-B Radiation.

(Edgew.) Heimerl is one of the most important genuine medicinal plants in Tibet, in which the special plateau habitat has been associated with its excellent medicinal quality and efficacy. However, the mechanisms by which environmental factors affect biosynthesis of secondary metabolic components remain unclear in this species.

Determination of dihydralazine based on chemiluminescence resonance energy transfer of hollow carbon nanodots.

The famous weak chemiluminescence (CL) system of potassium permanganate and sodium bisulfite (KMnO-HSO) was enhanced by the hollow fluorescent carbon nanodots (HCNs). The investigation of mechanism revealed that the enhanced CL was induced by the excited-state HCNs (HCNs), which could be produced from the electron-transfer annihilation of positively charged HCNs (HCNs) and negatively charged HCNs (HCNs) as well as by CL resonance energy transfer (CRET) from excited SO (SO)/O to HCNs. The dihydralazine sulfate (DHZS) had a diminishing effect on the CL of HCNs-KMnO-HSO system due to the competitive consumption of O.

Covalently Connected Polymer-Protein Nanostructures Fabricated by a Reactive Self-Assembly Approach.

The synthesis of polymer-protein nanostructures opens up a new avenue for the development of new biomaterials. In this research, covalently connected polymer-protein nanostructures were fabricated through a reactive self-assembly approach. Poly(tert-butyl methacrylate-co-pyridyl disulfide methacrylamide) (PtBMA-co-PPDSMA) was synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization.

Protein-Cross-Linked Triple-Responsive Polymer Networks Based on Molecular Recognition.

Hydrogels containing protein components are a type of promising biomaterial. In this paper, we designed triple-responsive polymer-protein networks based on molecular recognition. Reduced bovine serum albumin (BSA) was modified with multiple β-cyclodextrin (βCD) by thiol-disulfide exchange reaction.

[Sinonasal teratocarcinosarcoma: a clinical, radiologic and pathologic study of 5 cases].

Objective: To study the clinical, radiologic and pathologic features, as well as differential diagnosis of teratocarcinosarcoma in nasal cavity and paranasal sinuses.

Methods: Light microscopic examination and immunohistochemical study was performed in 5 cases of sinonasal teratocarcinosarcoma. The clinical, radiologic and pathologic features were analyzed and the literature was reviewed.
