BISERICA ORTODOXĂ DIN BASARABIA ȘI EDIFICAREA MONUMENTULUI ȚARULUI ALEXANDRU I

open access: yesAnalele Universităţii "Dunărea de Jos" din Galaţi. Fascicula XIX, Istorie
The present article, in fact, continues one of the previously presented communications regarding the involvement of the Orthodox Church in the "jubilee mania" process, triggered by the tsarist authorities, especially in the second decade of the 20th ...

Abyssal fauna of the UK-1 polymetallic nodule exploration area, Clarion-Clipperton Zone, central Pacific Ocean: Mollusca

open access: yesZooKeys, 2017
We present the first DNA taxonomy publication on abyssal Mollusca from the Clarion-Clipperton Zone (CCZ), central Pacific ocean, using material collected as part of the Abyssal Baseline (ABYSSLINE) environmental survey cruise ‘AB01’ to the UK Seabed ...

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Age and body size of Rana amurensis from northeastern China

open access: yesCurrent Zoology, 2011
Age and body size are two important demographic traits that determine the life history strategies of populations and species. We measured these two parameters of Rana amurensis, at a 900 m and a 500 m altitude site in northeastern China. At the two sites,

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Ruling the Commons. Introducing a new methodology for the analysis of historical commons

open access: yesInternational Journal of the Commons, 2016
Despite significant progress in recent years, the evolution of commons over the long run remains an under-explored area within commons studies. During the last years an international team of historians have worked under the umbrella of the 'Common Rules '

History of History of Physics

open access: yesActa Baltica Historiae et Philosophiae Scientiarum, 2016
The twelve decades of modern academic history of physics have provided enough material for the study of the history of history of physics, the focus of which is the development of the opinions and methods of historians of physics. The achievements of historians of physics are compared with the achievements of their objects of research, the physicists ...

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).
