From heart failure and kidney dysfunction to cardiorenal syndrome: TMAO may be a bridge.

The study of trimethylamine oxide (TMAO), a metabolite of gut microbiota, and heart failure and chronic kidney disease has made preliminary achievements and been summarized by many researchers, but its research in the field of cardiorenal syndrome is just beginning. TMAO is derived from the trimethylamine (TMA) that is produced by the gut microbiota after consumption of carnitine and choline and is then transformed by flavin-containing monooxygenase (FMO) in the liver. Numerous research results have shown that TMAO not only participates in the pathophysiological progression of heart and renal diseases but also significantly affects outcomes in chronic heart failure (CHF) and chronic kidney disease (CKD), besides influencing the general health of populations.

Suppressing TRAP1 sensitizes glioblastoma multiforme cells to temozolomide.

Glioma is a common malignant tumor of the central nervous system, accounting for ~50% of intracranial tumors. The current standard therapy for glioma is surgical resection followed by postoperative adjuvant radiotherapy and temozolomide (TMZ) chemotherapy. However, resistance to TMZ is one of the factors affecting prognosis.

Adaptive Changes Allow Targeting of Ferroptosis for Glioma Treatment.

Ferroptosis is a type of regulated cell death that plays an essential role in various brain diseases, including cranial trauma, neuronal diseases, and brain tumors. It has been reported that cancer cells rely on their robust antioxidant capacity to escape ferroptosis. Therefore, ferroptosis exploitation could be an effective strategy to prevent tumor proliferation and invasion.

PINK1: The guard of mitochondria.

PTEN-induced putative kinase 1 (PINK1) performs many important functions in cells and has been highlighted for its role in early-onset Parkinson's disease. In recent years, an increasing number of studies have revealed the involvement of PINK1 in regulation of a variety of cell physiological and pathophysiological processes, of which regulation of mitochondrial function remains the most prominent. As the "energy factory" of cells, mitochondria provide energy support for various cellular activities.

Misdiagnosis Analysis of Cervical Minimal Deviation Adenocarcinoma: a Report of Three Rare Cases and Literature Review.

Cervical minimal deviation adenocarcinoma (MDA) is a rare variant of cervical adenocarcinoma that is difficult to diagnose due to the deep location, endogenous growth pattern, deceptively benign appearance of tumor cells, and lack of connection to human papillomavirus (HPV). Cytological evaluation and biopsies offer suboptimal detection and transvaginal sonography or Magnetic Resonance Imaging (MRI) only reveal multiple lesions that mimic multiple benign nabothian cysts. Besides, standard screening, diagnostic tools, and treatments are not established.

Maghemite nanoparticles on electrospun CNFs template as prospective lithium-ion battery anode.

In this work, maghemite (γ-Fe2O3) nanoparticles were uniformly coated on carbon nanofibers (CNFs) by a hybrid synthesis procedure combining an electrospinning technique and hydrothermal method. Polyacrylonitrile nanofibers fabricated by the electrospinning technique serve as a robust support for iron oxide precursors during the hydrothermal process and successfully limit the aggregation of nanoparticles at the following carbonization step. The best materials were optimized under a carbonization condition of 600 °C for 12 h.

We report the use of highly porous, dense, and anisotropic TiO(2) derived from electrospun TiO(2)-SiO(2) nanostructures through titanate route in dye-sensitized solar cells. The titanate-derived TiO(2) of high surface areas exhibited superior photovoltaic parameters (efficiency > 7%) in comparison to the respective electrospun TiO(2) nanomaterials and commercially available P-25.

The review presented below summarizes the up-to-date research efforts in using one-dimensional TiO(2) nanomaterials in dye-sensitized solar cells. A brief account of the methods of synthesis of the anisotropic nanomaterials as well as their photovoltaic performance in DSCs was summarily presented. The usefulness of the materials as scattering layer in DSCs was also surveyed.

Facile solution deposition of ZnIn2S4 nanosheet films on FTO substrates for photoelectric application.

In this paper, ZnIn(2)S(4) perpendicular nanosheet films have been directly deposited on FTO substrates by a facile hydrothermal method and investigated as the electrode materials for solar cells. The crystal structure, morphology, and optical properties of the obtained ZnIn(2)S(4) films were characterized by measurements such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), energy dispersive spectrum (EDS), X-ray photoelectron spectrum (XPS) and UV-vis spectra. The results revealed a uniform perpendicular ZnIn(2)S(4) film with thickness of 4 μm and with an average nanosheet thickness of about 30 nm on FTO substrate, along with the band gap of 2.

Rice grain-shaped TiO2 mesostructures by electrospinning for dye-sensitized solar cells.

Nanofibers, produced by electrospinning a solution containing titanium tetra(IV) isopropoxide, polyvinyl acetate and acetic acid in N,N-dimethyl acetamide, upon sintering at 500 °C produce rice grain-shaped TiO(2) mesostructures. Each rice grain-shaped TiO(2) has a mixed crystal structure and high porosity and the mesostructures are found to have applications in dye-sensitized solar cells.
