A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Dualsteric and dual‐acting modulation of muscarinic receptors by antagonist KH‐5

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and purpose Muscarinic acetylcholine receptors are key therapeutic targets, and ligands engaging both orthosteric and allosteric sites may offer improved selectivity and efficacy. Here, we investigated whether the muscarinic antagonist KH‐5 acts as a dualsteric antagonist and defined its mode of interaction with muscarinic receptors.

NRF2/xCT‐Mediated Antioxidant Adaptation Attenuates Apoptosis Induced by ASCT2 Inhibition in Prostate Cancer

open access: yesCancer Science, EarlyView.
ASCT2 inhibition induces ROS accumulation and activates NRF2‐dependent xCT upregulation in prostate cancer. This adaptive response partially supports residual cystine acquisition and glutathione synthesis, whereas combined ASCT2 and xCT inhibition disrupts redox compensation and predominantly promotes apoptotic cell death.

Auxin response and PIN‐mediated transport in chlorophyte algae

open access: yesJournal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

“Why?”: C. Wright Mills on the Spirit of the Classical Sociological Tradition and Positivist Versus Critical Sociology

open access: yesSociology Lens, EarlyView.
ABSTRACT Despite their very diverse interests, the classical sociological thinkers were concerned with analyzing the dramatic social transformations in the wake of colonialism, slavery, and modern industrial capitalism as well as the multiple revolutions, particularly in relation to the new forms of social inequalities and power disparities.

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

open access: yesNew Phytologist, EarlyView.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Development of SiPM-based scintillator tile detectors for a multi-layer fast neutron tracker

open access: yesEPJ Web of Conferences, 2012
We are developing thin tile scintillator detectors with silicon photomultiplier (SiPM) readout for use in a multi-layer fast-neutron tracker. The tracker is based on interleaved Timepix and plastic scintillator layers.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, EarlyView.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Disruption of starch biosynthesis and triacylglycerol degradation impairs growth but improves photosynthesis in Arabidopsis

open access: yesNew Phytologist, EarlyView.
Proposed model for altered carbon partitioning in wild‐type (a) and tgd1 sdp1 adg1‐1 Arabidopsis triple mutant (b). Summary Enhancing lipid accumulation by redirecting carbon from starch to triacylglycerol (TAG) in vegetative tissues is a promising strategy for developing high‐energy‐density crops for bioenergy production. However, our understanding of
