We report an automated classifier to detect the presence of basal cell carcinoma in images of mouse skin tissue samples acquired by polarization-sensitive optical coherence tomography (PS-OCT). The sensitivity and specificity of the classifier based on combined information of the scattering intensity and birefringence properties of the samples are significantly higher than when intensity or birefringence information are used alone. The combined information offers a sensitivity of 94.4% and specificity of 92.5%, compared to 78.2% and 82.2% for intensity-only information and 85.5% and 87.9% for birefringence-only information. These results demonstrate that analysis of the combination of complementary optical information obtained by PS-OCT has great potential for accurate skin cancer diagnosis.

Trichoblastic carcinoma, trichoblastoma, trichoepithelioma, and basal cell carcinoma are histologically characterised by basaloid cell proliferation. In this report, we describe the case of a 76-year-old man who presented with trichoblastic carcinoma admixed with histological features of trichoblastoma, trichoepithelioma, and basal cell carcinoma. These tumours may not be situated separately but must be related to each other in terms of tumorigenesis.

The colonial system of integration (CSI) provides intracolonial nutrient supply in many gymnolaemate bryozoans. In Ctenostomata, its presence is known for species with stolonal colonies, for example, vesicularioideans, but its structure is almost unexplored. The CSI is thought to be absent in alcyonidioideans and other ctenostomes.

The cornea, the anterior meniscus-shaped transparent and refractive structure of the eyeball, is the first mechanical barrier of the eye. Its functionality heavily relies on the health of its endothelium, its most posterior layer. The treatment of corneal endothelial cells (CECs) deficiency is allogeneic corneal graft using stored donor corneas.

The phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway is frequently hyperactivated in triple-negative breast cancers (TNBCs) associated with poor prognosis and is a therapeutic target in breast cancer management. Here, we describe the effects of repression of mTOR-containing complex 1 (mTORC1) through knockdown of several key mTORC1 components or with mTOR inhibitors used in cancer therapy. mTORC1 repression results in an ∼10-fold increase in extracellular matrix proteolytic degradation.

The salinization of the water environment worldwide is increasing, which has brought great challenges to the sustainability of fish farming of aquatic animals. Three NaHCO concentration groups (0 mmol/L, 20 mmol/L, and 60 mmol/L) were set up in this study to investigate growth and metabolic differences between diploid and triploid crucian carp under saline-alkaline stresses. This study utilized UPLC-QTOF/MS metabolomics to analyze significant metabolites and metabolic pathways in the serum of diploid and triploid crucian carp, exposing them to different NaHCO concentrations in saline-alkaline habitats, elucidating the mechanism of their metabolic differences.
