Comparative Study of Cutaneous Squamous Cell Carcinogenesis in Different Hairless Murine Models.

: In recent decades, a significant global increase in the incidence of non-melanoma skin cancer has been observed. To explore the pathogenesis of and potential therapeutic approaches for squamous cell carcinoma, various in vivo studies using mouse models have been conducted. However, investigations comparing different hairless mouse models, with or without melanin, as well as models with hypercholesterolemia and immunosuppression, in terms of their ability to induce squamous cell carcinoma have yet to be undertaken.

Stimulation of fracture mineralization by salt-inducible kinase inhibitors.

Introduction: Over 6.8 million fractures occur annually in the US, with 10% experiencing delayed- or non-union. Anabolic therapeutics like PTH analogs stimulate fracture repair, and small molecule salt inducible kinase (SIK) inhibitors mimic PTH action.

Collaborating with non-radiological clinical colleagues.

Paediatric radiology is a challenging and intriguing subspecialty, dealing with children, guardians and non-radiological clinical colleagues. Paediatric radiologists are routinely in contact with numerous paediatric and surgical subspecialties, all having different needs, perceptions, prioritisations and expectations. Moreover, the radiologist is part of the team of radiographers, sonographers, nurses and secretaries, assisted by appropriate equipment and electronic tools.

Magnetic resonance imaging of fetal vascular malformations.

Vascular anomalies develop during fetal life and can be detected on prenatal ultrasonography and fetal magnetic resonance imaging. Diagnosis of lymphatic, venous, and arteriovenous malformations, as well as congenital hemangiomas and other congenital vascular tumors, may be challenging. The benign vascular anomalies may be difficult to differentiate from malignancies with a similar appearance.

Regulation of intracellular cAMP levels in osteocytes by mechano-sensitive focal adhesion kinase via PDE8A.

Osteocytes are the primary mechano-sensitive cell type in bone. Mechanical loading is sensed across the dendritic projections of osteocytes leading to transient reductions in focal adhesion kinase (FAK) activity. Knowledge regarding the signaling pathways downstream of FAK in osteocytes is incomplete.
