The FEBS Journal, EarlyView.Enteroendocrine L cells function as chemosensors in the intestine. Using the L‐cell line GLUTag, we show that distinct nutrients trigger different combinations of co‐secretion of GLP‐1 and neurotransmitters: D‐glucose evokes GLP‐1, glutamate, and ATP; L‐glutamine evokes GLP‐1 and glutamate; sucralose and butyrate evoke only GLP‐1.

La terra dove nulla scompare per sempre [PDF]
Kaiak, 2015 The traditional cultures of Native American tribes and populations have been humbled for a very long time by the WASP dominant vision of the US destiny. Through particular laws like the sadly well-known Indian Removal Act (1830), the

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

An Experimental Study of Temperature-Gradient Metamorphism
, 1980 The present study was carried out with a view to quantifying the effects of the main parameters ot temperature-gradient metamorphism. Cold-room simulation tests showed crystal growth to be an increasing function of the temperature-gradient modulus with a

Ophiolite Metamorphism and Ocean-Floor Metamorphism.
Journal of Geography (Chigaku Zasshi), 1995 Ophiolites of primary igneous origin have been more or less modified by later metamorphic processes, and there are several types of ophiolite metamorphism such as (1) the low-pressure type as recognized in ophiolites of the Mediterranean, Alps, Oman, Newfoundland, Chile, Taiwan, Borneo, California Coast Range, Hidaka Western Zone, and Horokanai, (2 ...

P‐T Uncertainty in Subsolidus Metamorphic Systems: Sources, Patterns and Controls
Journal of Metamorphic Geology, EarlyView.ABSTRACT Phase equilibrium modelling of metamorphic rocks is subject to multiple, superimposed sources of uncertainty that affect pressure–temperature (P$$ P $$‐T$$ T $$) estimates, making it difficult to independently distinguish and evaluate the contribution of each source.

Olivine-chrome-spinel equilibrium in chromitites and ultramafites of Rai-Iz massif, Polar Urals
Литосфера, 2016 Olivine and chrome-spinel compositions from chromitites and ore-bearing metamorphosed ultramafic rocks of Rai-Iz massif were compared. It was established that olivine and spinel ferruginosity are directly proportional and increase monotonically from ...

Testing for the presence of a terrane boundary within Neoproterozoic (Dalradian) to Cambrian siliceous turbidites at Callander, Perthshire, Scotland [PDF]
, 1999 The Southern Highland Group (Dalradian) and Keltie Water Grit Formation, which includes the Lower Cambrian Leny Limestone, form an inverted, 1.4 km thick, largely arenaceous, sequence at Callander.
