Plagioclasites from chromite-bearing ultramafic rocks of the Rai-Iz massif

Литосфера, 2016
The corundum-bearing and without-corundum plagioclasites from chromite-bearing ultramafic rocks of Rai-Iz massif were studied. Chemical composition of the rock-forming minerals and rock geochemical characteristics was determined.

Alluvial to lacustrine sedimentation in an endorheic basin during the Mio-Pliocene: The Toro Negro Formation, Central Andes of Argentina [PDF]

, 2018
A 2400 m-thick sedimentary column belonging to the Toro Negro Formation was recorded along the Quebrada del Yeso, Sierra de Los Colorados (Vinchina Basin), La Rioja province, NW Argentina. The Vinchina basin is a good example of a closed basin surrounded

Age and genetic interrelation of ultramafic rocks, rodingites and chlorite-carbonate rocks of the Karabash massif (South Urals)

Литосфера, 2016
The age of ulramafic rocks of the Karabash massif (1720-1740 Ma), the minimum age of their protolith (1830 Ma), and the age of formation of rodingites (438.5 ± 15 Ma) and chlorite-carbonate rocks (404.4 ± 8.8 Ma) were determined on the basis of the ...

Hf isotopes from Palawan Continental Terrane, Philippines-clues to the evolution of sediment sources

Terrestrial, Atmospheric and Oceanic Sciences, 2018
The age spectra of detrital zircons in meta-sediments from Palawan Island, Mindoro Island, Tablas, and the Buruanga Peninsula of Panay Island in the Central Philippines provide evidence for the provenance of these zircons in the northern part of the ...

Neutrophil‐Driven Cascade‐Targeted Nanocarriers Restore Mitochondrial Homeostasis to Ameliorate Renal Ischemia–Reperfusion Injury

Advanced Science, EarlyView.
A neutrophil‐mediated dual‐targeting liposome (NKN‐LNP) is developed to treat renal ischemia–reperfusion injury. The system enables spatiotemporally controlled delivery of NMN to injured tubules via MMP‐2/9 activation and KIM1 recognition, restoring mitochondrial function through NAD+‐SIRT3 signaling and preventing the transition from acute kidney ...

Metabolic Imbalance Triggers Adaptive Remodeling to Accelerate Diploidization in Murine Haploid Embryonic Stem Cells

Advanced Science, EarlyView.
In this article, Shuai and colleagues demonstrate that metabolic remodeling drives self‐diploidization in murine haploid ESCs (haESCs). Mitochondrial dysfunction and imbalanced pyruvate metabolism underlie this process. Genome‐wide screening using haESCs identifies key mitochondrial quality‐control related genes, enabling a metabolism‐based medium that

Provenance and Paleogeography of the 25-17 Ma Rainbow Gardens Formation: Evidence for Tectonic Activity at Ca. 19 Ma and Internal Drainage rather than Throughgoing Paleorivers on the Southwestern Colorado Plateau [PDF]

, 2018
The paleogeographic evolution of the Lake Mead region of southern Nevada and northwest Arizona is crucial to understanding the geologic history of the U.S. Southwest, including the evolution of the Colorado Plateau and formation of the Grand Canyon.
