An unusual tumor in the descending colon with human chorionic gonadotropin-beta (HCG-beta) production and histological features of a "glassy cell" carcinoma is presented. Glassy cell carcinoma has been described in the uterus and fallopian tubes as well as the cervix, but in these locations the tumor is not HCG-beta producing. Glassy cell carcinomas have been described in some cases as having glandular and squamous differentiation as well as marked cellular pleomorphism. The tumors are generally associated with a poor prognosis.

Liver cancer is globally the most frequent fatal malignancy, and its identification is critical for making clinical decisions about treatment options. Pathological diagnostics and contemporary imaging technologies provide insufficient information for tumor identification. Hydrogen peroxide (HO), an emerging biomarker is a powerful oxidant found in the tumor microenvironment, and stimulates the invasion, proliferation, and metastasis of liver cancer cells.

Monitoring HO levels in live cells is essential due to its superior stability and possible severity inside the cell. The quest for a superior platform capable of detecting cellular-level hydrogen peroxide (HO) concentrations without necessitating the use of high-cost enzymes is of utmost importance. Here, the quantification of intracellular HO concentrations has been performed using silver metal polymer-based nonenzymatic electrochemical detection.

Solid-state batteries offer significant advantages but present several challenges. Given the complexity of these systems, it is good practice to begin the study with simpler models and progressively advance to more complex configurations, all while maintaining an understanding of the physical principles governing solid-state battery operation. The results presented in this work pertain to cells without traditional electrodes, thus providing a foundation for guiding the development of fully functional solid-state cells.

A Pb-containing PtAu nanoflower electrocatalyst was deposited on the cathode via galvanic replacement reaction in a double-cabin galvanic cell (DCGC) with a Cu plate as the anode, a multiwalled carbon nanotube (MWCNT) modified glassy carbon electrode (GCE) as the cathode, 0.1 M HClO aqueous solution as the anolyte, and Pb-containing Pt salt and Au salt mixed aqueous solution as the catholyte, respectively, and the electrocatalytic performance of the modified electrode toward methanol oxidation in the alkaline medium was investigated. Electrochemical studies reveal that the stripping of bulk Cu can induce underpotential deposition (UPD) of Pb on Pt during the galvanic replacement reaction, which affects the morphology and composition of Pb-containing PtAu nanoparticles.
