Variable Upper Mantle Geochemical Processes Constrained From Independent Component Analysis of the Fizh Massif, Northern Oman Ophiolite

Geochemistry, Geophysics, Geosystems
We statistically analyzed the whole‐rock compositions of peridotites in the Oman ophiolite using a multivariate statistical technique called independent component analysis (ICA) to better understand the processes within the ophiolitic mantle section that

Evolution of the volcanic mechanism in the central part of the Urumieh-Dokhtar magmatic arc

Journal of Economic Geology, 2021
Introduction Cenozoic volcanic activities in the Urumieh-Dokhtar Magmatic Arc (UDMA) have occurred in three main pulses of Eocene, upper Oligocene-Pliocene, and Pio-Quaternary (Dilek et al., 2010, Sayari, 2015).

"Early partial melting" in annealed natural cordierites

European Journal of Mineralogy, 2002
Natural cordierite crystals with a range of Mg:Fe ratios have been annealed at a range of temperatures between 1200 and 1430°C (under controlled f o2 ), after previously being annealed at 900 °C to drive off any volatiles contained within their channels. Complex microstructures were observed in these samples by transmission electron microscopy.

PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

Molecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

The 1.79 Ga Särkilahti leucogranite – a horizontal magma layer below granulite-grade migmatites in SE Finland [PDF]

Bulletin of the Geological Society of Finland, 2019
The heterogeneous, peraluminous Särkilahti garnet-cordierite leucogranite occupies ~ 75 km2 area in Svecofennian granulite-grade terrain of SE Finland. Country rocks are metasedimentary garnet-cordierite-biotite migmatites with some orthopyroxenegarnet ...

Recrystallization and Melting of Partially Melted Stark Rubber

Rubber Chemistry and Technology, 1967
Abstract Two specimens from a piece of stark rubber which had a melting temperature originally at 41° C were partially melted at 38° C and allowed to stand for 11 years, one at about 25° C, the other at 38° C. The first showed a continuous slow decrease in specific volume, while the second increased slowly in volume for 5 months and remained ...

Spontaneous small‐scale melt segregation in partial melts undergoing deformation [PDF]

Geophysical Research Letters, 1989
A partial melt undergoing large scale deformation is shown to be unstable with respect to small scale redistribution of melt, provided the shear viscosity of the matrix depends on melt fraction. In the physically realistic case where melt “softens” the matrix, melt migrates along the direction parallel to the axis of minimum compressive stress and ...

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...
