Article Synopsis
- Covalent semiconductors from the carbon nitride family show potential in artificial photosynthesis, using sunlight to split water and convert CO into useful chemicals.
- The study employs in-situ spectroscopic techniques to observe how surface interactions in carbon nitride change under conditions mimicking artificial photosynthesis.
- Findings indicate that water adsorption and light exposure alter surface electron density, facilitating photocatalysis through a specific mechanism known as proton-coupled electron transfer, which is crucial for developing more efficient photocatalysts.
Purpose: The purpose of this study was to report the management of chemoimmunotherapy-resistant ocular surface squamous neoplasia (OSSN) with iodine-125 (I-125) brachytherapy.
Methods: A 36-year-old man presented to the clinic with biopsy-proven OSSN that covered ∼70% of the corneal surface and extended to the 6 o'clock position of the inferior limbus of the OS. The visual acuity was 20/20 in the OD and 20/40 in the affected OS.

Article Synopsis
- - The incorporation of tetrakis(4-carboxyphenyl)porphyrin (HTCPP) into partially exchanged Zn poly(heptazine imide) (PHI) enhances light absorption without changing the structure of PHI, achieving optimal performance at a 20 wt % loading.
- - Under visible light irradiation, the resulting photosensitized system (TCPP20%@(Zn/K)-PHI) produced significant amounts of hydrogen gas, demonstrating an apparent quantum yield of 5.5% at 400 nm and 2% at 700 nm, highlighting its efficiency compared to other referenced photocatalysts.
- - Findings from transient absorption spectroscopy and photocurrent measurements indicate effective charge separation and electron transfer processes,
Protein S (PROS1) has recently been identified as a ligand for the TAM receptor MERTK, influencing immune response and cell survival. The PROS1-MERTK interaction plays a role in cancer progression, promoting immune evasion and metastasis in multiple cancers by fostering a tumor-supportive microenvironment. Despite its importance, limited structural insights into this interaction underscore the need for computational studies to explore their binding dynamics, potentially guiding targeted therapies.
