Abstract Our recent paper (Nishiyama et al. in Earth Planets Space 73:126, 2021) suggested that the sealing time of a crack-seal event recorded quartz-filled shear veins Makimine mélange may temporally increase or decrease. Nishiyama (Earth describes optical estimates vapor–liquid ratio primary two-phase fluid inclusions between solid inclusion bands veins. The variation was used as an indicato...

One of the fundamental tools in radiation biology is a formalism describing time-dose relationships. For example, there is a need for reliable predictions of radiotherapeutic isoeffect doses when the temporal exposure pattern is changed. The most commonly used tool is now the linear-quadratic (LQ) formalism, which describes fractionation and dose-protraction effects through a particular functio...

Since the first laboratory experiments of M. Carey Lea and the original definition by F. W. Ostwald at the end of the 19th century, mechanochemistry, a field treating chemical changes induced in substances as a result of applied mechanical stress, has been evolved as an important area of chemistry from the viewpoint of both the fundamental research and applications (Takacs, 2004; Boldyrev & Tka...

In this study, it has been determined whether the arbuscular mycorrhizal (AM) symbiosis is able to alter the pattern of dehydrin (LEA D-11 group) transcript accumulation under drought stress, and whether such a possible alteration functions in the protection of the host plants against drought. Two dehydrin-encoding genes have been cloned from Glycine max (gmlea 8 and gmlea 10) and one from Lact...

PURPOSE To review current opinion on the production and temporal evolution of low-LET radiobiological damage. METHODS Standard cell survival models which model repair/misrepair kinetics in order to quantify dose-response relations and dose-protraction effects are reviewed and interrelated. Extensions of the models to endpoints other than cell survival, to multiple or compound damage processin...

Vitiligo is a relatively common, acquired depigmenting disease caused by the loss of epidermal melanocytes. Oxidative stress known to participate in initiation vitiligo triggering autoimmunity. In this study, we tried identify factors serving as bridge between oxidative and autoimmunity vitiligo. According RNA sequencing analysis on H2O2-treated melanocytes, interferon-stimulated gene 15 (ISG15...
