Background: In actinic keratosis (AK), field cancerization describes areas of skin where multiple visible AK lesions are surrounded by healthy looking skin containing non-visible (subclinical) lesions. As all AK lesions have a risk of progression to cutaneous squamous cell carcinoma, experts advise field-directed treatment. Photodynamic therapy (PDT) is an effective field-directed treatment option for AK; however, long-term efficacy data are still scarce.

This study aimed to analyze the influence of biomechanical loading on DRAM1 expression in periodontal cells and tissues.
Methods: Human periodontal ligament (PDL) fibroblasts were stimulated with different pressure protocols, physiological load and overload, in the presence and absence of autophagy inhibitor 3-methyladenine (3-MA) and compared with untreated cells.
Introduction: Tamoxifen may adversely affect cognitive function by interfering with estrogen action in the brain. Despite growing evidence for a relationship between tamoxifen and cognitive problems, findings remain inconclusive. While some tamoxifen-related side effects seem exposure-dependent with concentrations of tamoxifen or its main metabolite, endoxifen, this has never been investigated for cognitive function.

It is suggested to play an important role in the development of psychiatric disorders like post-traumatic stress disorder (PTSD). Individuals with PTSD usually show decreased BDNF levels in serum.
