The authors analysed morphological changes and provided morphological assessment of the parenchyma, stroma, vessels and necrosis in the squamous cell lung carcinoma tissue of 40 patients without preliminary irradiation, 40 patients after gamma-beam therapy and 49 patients after radiotherapy combined with induced hyperglycemia (IH). The total focal dosage was 20 Gy (5 fractions during a week). In 25 patients IH was followed by irradiation and in 24 patients it followed irradiation. Operation was performed on the 7-8th day after therapy was initiated. It was concluded that preoperative gamma-beam therapy followed by IH produced the most noticeable damaging effect on squamous cell lung carcinoma.

Understanding how epithelial cells in the female reproductive tract (FRT) differentiate is crucial for reproductive health, yet the underlying mechanisms remain poorly defined. At birth, FRT epithelium is highly malleable, allowing differentiation into various epithelial types, but the regulatory pathways guiding these early cell fate decisions are unclear. Here, we use neonatal mouse endometrial organoids and assembloid coculture models to investigate how innate cellular plasticity and external mesenchymal signals influence epithelial differentiation.

Potential trend of regenerative treatment for type I diabetes has been introduced for more than a decade. However, the technologies regarding insulin-producing cell (IPC) production and transplantation are still being developed. Here, we propose the potential IPC production protocol employing mouse gingival fibroblast-derived induced pluripotent stem cells (mGF-iPSCs) as a resource and the pre-clinical approved subcutaneous IPC transplantation platform for further clinical confirmation study.

Aflatoxin B1 (AFB1) is a class 1 carcinogen and mycotoxin known to contribute to the development of hepatocellular carcinoma (HCC), growth impairment, altered immune system modulation, and malnutrition. AFB1 is synthesized by Aspergillus flavus and is known to widely contaminate foodstuffs, particularly maize, wheat, and groundnuts. The mechanism in which AFB1 causes genetic mutations has been well studied, however its metabolomic effects remained largely unknown.
