Fluid inclusions in rocks of the Archean high-grade Varpaisjärvi-Lapinlahti area, central Finland [PDF]
Bulletin of the Geological Society of Finland, 1992 Fluid inclusions both in matrix quartz of metamorphic rocks and in quartz veins from five samples from the Archean high-grade Varpaisjärvi-Lapinlahti area were examined with microthermometric methods. Two types of fluid inclusions were observed: CO2-rich

Late Precambrian U-Pb titanite age for peak regional metamorphism and deformation (Knoydartian orogeny) in the western Moine, Scotland [PDF]
, 2003 There has been controversy over the number and timing of orogenies in the Precambrian Moine block in the Scottish Caledonides since the earliest radiometric dating in the 1960s. This work challenges a recent hypothesis, that this sector of the Laurentian

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease
Arthritis &Rheumatology, EarlyView.Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of
