Various cytochrome P450 enzymes (CYPs) that contribute to drug metabolism are expressed in the skin. However, variation among individuals in CYP expression profiles is not well-understood.To investigate CYPs related to the metabolism of transdermal preparations in Japan, multiple skin tissue specimens of individuals of Japanese descent were prepared, and the mRNA expression levels of , , and were measured.

Endoscopic mastectomy followed by immediate breast reconstruction with fat grafting for breast cancer.

Background: Although endoscopic mastectomy has been associated with good tolerance and enhanced patient satisfaction, limitations such as the implant or flap size for reconstruction with small incisions remain unresolved. Fat grafting (FG) can expand tissue volume with pinhole skin incisions. Herein, we evaluated the safety and efficacy of endoscopic mastectomy followed by immediate FG.

The RNA-binding protein Msi2 regulates autophagy during myogenic differentiation.

Skeletal muscle development is a highly ordered process orchestrated transcriptionally by the myogenic regulatory factors. However, the downstream molecular mechanisms of myogenic regulatory factor functions in myogenesis are not fully understood. Here, we identified the RNA-binding protein Musashi2 (Msi2) as a myogenin target gene and a post-transcriptional regulator of myoblast differentiation.

Benralizumab treatment in an elderly patient with eosinophilic esophagitis resulted in remission: a case report.

Background: Interleukin-5 (IL-5) has recently been shown to play a crucial role in eosinophil-mediated diseases, implying that an IL-5 receptor alpha chain (IL-5Rα) antibody (benralizumab) can be effective against eosinophilic esophagitis (EoE). Here, we present a case in which benralizumab significantly improved the symptoms and signs of an elderly Asian woman with EoE who had inadequate response to existing treatments. Case presentation A 73-year-old woman with an 8-year history of bronchial asthma (BA) and a 7-year history of dysphagia presented to our hospital with worsening dysphagia, vomiting, chest pain, and difficulty in eating.
