COMPONENTS OF ANTARCTIC PLANTS WHICH INHIBIT SEED GERMINATION (Twelfth Symposium on Polar Biology)

The inhibitions of seed germination and microbe growth by extracts of antarctic plants were examined. Assays for non-specific toxin activity of the extracts were also carried out using soybean leaves. Three kinds of mosses, three kinds of lichens and five kinds of algae were extracted with methanol. The methanol extracts were evaporated, and the residues were extracted with chloroform. The chloroform layers and the aqueous layers were subjected to assays. Among them, chloroform extracts of two lichens inhibited seed germination and microbe growth. Purification of these extracts, and structure elucidation of the active components were discussed

Why not de-intensification for uterine cervical cancer?

The majority of uterine cervical cancer is known to be related to human papillomavirus (HPV), and HPV-related tumors are known to be radio-sensitive. In the management of HPV-related oropharyngeal cancer, de-intensification of treatment has been attempted; however, no such attempt is performed in the management of cervical cancer. The aim of this study was to identify a group of patients who can safely be treated by de-escalated treatment intensity
