Purpose: To compare the microstructure of the corneal endothelial transition zone in different laboratory animals.
Methods: Flat-mount corneas of rabbits, rats, and mice were stained with Alizarin Red S (ARS) and observed using scanning electron microscopy (SEM). The progenitor cell markers p75 neurotrophin receptor (p75NTR), SRY-box transcription factor 9 (SOX9), leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5), telomerase reverse transcriptase (TERT), and proliferation marker K-67 were examined in the flat-mounted corneas of three laboratory animals using immunofluorescence microscopy.
Article Synopsis
- The study focused on how the austenite (γ) phase in high chromium cast irons (HCCIs) dissolves when immersed in a specific acidic solution, revealing that primary and eutectic γ phases dissolve at different voltage levels.
- Results showed that the primary γ phase predominantly dissolved within the first hour of immersion, while both primary and eutectic γ phases dissolved thereafter, but carbide phases remained unaffected.
- The research found that increasing carbon content in the HCCIs led to a higher corrosion rate, attributed to changes in the electrochemical potential differences between γ and carbide phases caused by the addition of carbon.
Article Synopsis
- The study examined how the precipitation-hardened UNS N07718 alloy is passivated in a solution of 5 wt% NaCl and 0.5 wt% CHCOOH.
- Cyclic potentiodynamic polarisation showed that the alloy maintained a stable passive state without switching to a different behavior during testing, and the passive film improved in electrical resistivity over time.
- Analysis revealed that the passive film consisted of layers rich in chromium and iron, and changes in the film's composition were linked to the alloy's corrosion resistance in harsh conditions.
The effect of adding C on the passivity of hypoeutectic high chromium cast iron (HCCI) was investigated in a pH 8.4 boric-borate buffer solution. The microstructure of HCCI is composed of austenite and carbide phases, whose fractions and chemical compositions are influenced by the amount of C added.

Inflammation is an essential immune response to exogenous stimuli such as infection and injury. Although inflammation is a necessary host-defense mechanism, chronic inflammation is associated with the continuous local or systemic release of inflammatory mediators, non-cytokine mediators, such as ROS and NO, and inflammatory cytokines are strongly implicated in the pathogenesis of various inflammatory disorders.

The WO-Ni film library was deposited by thermal coevaporation on an indium tin oxide (ITO)-coated glass substrate in an atomic Ni concentration range from 2.

Long non-coding RNAs (lncRNAs) are frequently and aberrantly expressed in various human cancers and are known to play a role in cancer pathogenesis. The aim of this study was to analyze the expression of lncRNA-ATB in HCC and investigate the implications for prognoses.
