Article Synopsis
  • The study assesses the effects of Japan's 2021 Ordinance revision on radiation safety practices, particularly in hospitals and the role of radiology technologists.
  • A two-phase web-based survey was conducted among hospitals to gather data on radiation worker management and facility resources.
  • Results showed an increase in use of lens-specific dosimeters but only minor improvements in protective eyewear availability and consistent involvement of technologists, with larger hospitals generally following better safety protocols.

Article Synopsis
  • Caveolin-1 (CAV-1) is a protein that inhibits various kinases and regulates inflammation, and its downregulation in psoriatic skin cells increases inflammation and cell growth.
  • A study found that a peptide derived from CAV-1, called sB, was more effective than other modified peptides at reducing symptoms in a psoriasis model, improving skin condition and reducing immune cell infiltration.
  • sB not only suppressed signaling pathways associated with inflammation but also inhibited new blood vessel formation, making it a promising therapeutic option for treating psoriasis.

Nearly forty years have passed since the Chornobyl Nuclear Power Plant accident, which resulted in childhood and adolescent thyroid cancers increasing due to internal exposure to iodine-131. Therefore, the Fukushima Daiichi Nuclear Power Station accident, in 2011, raised serious anxiety about potential risks of thyroid cancers. Considering the causal relationship between thyroid cancer and the Chornobyl accident, radiation dose to the thyroid due to this accident should be considered carefully.

Systemic sclerosis (SSc) is characterized by dermal fibrosis with a female predominance, suggesting a hormonal influence. Patients with SSc have elevated interleukin (IL)-6 levels, and post-menopausal women and older men also have high estradiol (E2) levels. In the skin, IL-6 increases the enzymatic activity of aromatase, thereby amplifying the conversion of testosterone to E2.

Background: The maxilla comprises horizontal and vertical buttresses, each with specific functions, supporting various organs, such as the eyes, nose, and oral cavity. Notably, they combine to form a three-dimensional structure, which enables the buttresses to provide their inherent support strength. However, reconstructing the maxilla after maxillectomy by assembling new buttresses is challenging.
