PP2Acα regulates epidermal cell proliferation via the EGFR/AKT/mTOR pathway in psoriasis‐like skin lesions caused by PPP2CA deficiency

Experimental Dermatology, 2022
Psoriasis, a common skin disease, endangers human physiological and mental health; however, its pathogenesis remains unclear. Keratinocyte proliferation is a typical pathological characteristic of psoriasis. Serine/threonine protein phosphatase 2A (PP2A)

Hand Skin Temperature after Local Cold Test: Thermal Imaging Observation and Mathematical Computation

2021 Ural Symposium on Biomedical Engineering, Radioelectronics and Information Technology (USBEREIT), 2021
A thermographic study of the body's reaction to a cold test (immersion of the arm's hand in cold water for 1 min) of 48 volunteers was carried out. The process of recovering the temperature of the cooled hand had an oscillatory character. Fluctuations in
