Protective Effect of Amber Extract on Human Dopaminergic Cells against 6-Hydroxydopamine-Induced Neurotoxicity

open access: yesMolecules, 2022
Parkinson’s disease (PD) is the second most common progressive neurodegenerative disease, after Alzheimer’s disease. In our previous study, we found that amber—a fossilized plant resin—can protect cells from apoptosis by decreasing the generation of ...

New records of mosses from Dominican amber [PDF]

open access: yes, 2001
Hypnum cupressiforme, Entodon macropus, Homalia glabella and Calyptothecium duplicatum are recorded as new from Dominican amber. Earlier records of Neckera spec. have to be transferred to Calyptothecium duplicatum. These records raise the total number of

A new fossil piddock (Bivalvia: Pholadidae) may indicate estuarine to freshwater environments near Cretaceous amber-producing forests in Myanmar

open access: yesScientific Reports, 2021
The lower Cenomanian Kachin amber from Myanmar contains a species-rich assemblage with numerous plant and animal fossils. Terrestrial and, to a lesser degree, freshwater species predominate in this assemblage, while a few taxa with marine affinities were

Archaeal protein containing domain of unknown function 2193 undergoes oligomeric reconfiguration upon iron–sulfur cluster binding

open access: yesFEBS Letters, EarlyView.
This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Fringe tracking performance monitoring: FINITO at VLTI

open access: yes, 2012
Since April 2011, realtime fringe tracking data are recorded simultaneously with data from the VLTI/AMBER interferometric beam combiner. Not only this offers possibilities to post-process AMBER reduced data to obtain more accurate interferometric ...

Are You There, God? It’s Me, the Theist: On the Viability and Virtue of Non-Doxastic Prayer [PDF]

open access: yes, 2022
In this article, I explore the possibility of what I call “non-doxastic theistic prayer”, namely prayer that proceeds without full belief in God – or in the kind of God who could be the recipient of such prayer.

Ethics, law, and politics in palaeontological research: The case of Myanmar amber

open access: yesCommunications Biology, 2021
Fossil material in amber from Myanmar can provide important insights into mid-Cretaceous forest ecosystems. However, Myanmar amber has been receiving increased international attention due to reported links between amber mining and the ongoing ...

TOMM20 as a driver of cancer aggressiveness via oxidative phosphorylation, maintenance of a reduced state, and resistance to apoptosis

open access: yesMolecular Oncology, EarlyView.
TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.
