Early 20th C Russian painting? Raman identification of modern pigments on a pastel supposedly Painted by the renowned artist Natalia Goncharova [PDF]

, 2014
A pastel painting considered to have been painted by renowned Russian artist Natalia Goncharova in c. 1913 has been shown by Raman microscopy of the pigments to have been painted after 1952, with the identification of dioxazine violet.

Studying pigments on painted plaster in Minoan, Roman and Early Byzantine Crete. A multi-analytical technique approach [PDF]

, 2011
Wall paintings spanning two millennia of Cretan painting history and technology were analysed in an effort to determine similarities and evolutions of painting materials and technology. A multi-technique approach was employed that combined the use of (a)

Partial quantification of pigments extracted from the zooxanthellate octocoral Sinularia flexibilis at varying irradiances

, 2010
Chlorophyll-a (chl-a) and carotenoid pigments of the zooxanthellate octocoral Sinularia flexibilis were analyzed using high performance liquid chromatography following exposure to three light intensities for over 30 days. From the coral fragments located

Photochemical colour change for traditional watercolour pigments in low oxygen levels

, 2015
An investigation for light exposure on pigments in low-oxygen environments (in the range 0–5% oxygen) was conducted using a purpose-built automated microfadometer for a large sample set including multiple samples of traditional watercolour pigments from ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Clay-assisted dispersion of organic pigments in water

, 2014
We reported a new method for dispersing insoluble organic pigments (OPs) in water by simply pulverizing with the selected clay. The smectite clay of synthetic fluorinated mica (Mica) enabled to homogenize the pigments due to its inherent colloidal ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
