August 2013 in “The Journal of Cell Biology” This study found that Wnt secretion is important for skin homeostasis in mice, as Evi-deficient mice developed skin lesions resembling psoriasis and showed immune cell imbalance.
October 2021 in “Journal of Investigative Dermatology” This study found no significant epidemiological association between male androgenetic alopecia and severe Covid-19, but suggests a potential shared biological basis in specific pathways.
May 2007 in “Proceedings of the National Academy of Sciences of the United States of America” Alexander the Great's engineers built a causeway using a natural sand bridge, some tiger moths avoid bats by mimicking toxic relatives' sounds, early metabolism and RNA enzymes support the ancient RNA world theory, and vitamin D is crucial for hair growth and its absence can cause baldness.
October 2024 in “Current Issues in Molecular Biology” In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.
