Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Examining the Einstein-Bergson Controversy about Time Considering the Time-Energy Uncertainty Principle [PDF]

Journal of Philosophical Investigations
This paper revisits the famous 1922 debate between Einstein and Bergson on the nature of time, outlining its central philosophical and scientific points of contention and re-evaluating them in light of developments in quantum physics.

Relativity theory between structural and dynamical explanations [PDF]

, 2006
In this review article I discuss Harvey Brown’s recent book Physical Relativity (OUP, 2005) by presenting and criticizing some of his main arguments in favour of a dynamical underpinning of rods contractions and clocks dilations. The problem about how we

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Relative and Pseudo-Relative Clauses in Slovene [PDF]

Slovene Linguistic Studies, 2007
 The author explores the various types of relative clauses in Slovene, focusing on a construction that has traditionally been assumed to be a special type of relative clause in which there seems to be a mismatch between the number feature of the clitic pronoun and that of the relative head, e.g., Najboljši iskalec si, [RC kar smo jih imeli.]1 best-Nom ...

Konštruktivizmus, realizmus a obrat k jazyku

Filosofický časopis, 2021
This paper focuses primarily on the realism-constructivism debate. Firstly, I clarify Goodman’s three main arguments for constructivism, and then I deal with the critical response to this doctrine by proponents of Devittian common-sense realism and ...

Coordinates, observables and symmetry in relativity [PDF]

, 2007
We investigate the interplay and connections between symmetry properties of equations, the interpretation of coordinates, the construction of observables, and the existence of physical relativity principles in spacetime theories. Using the refined notion

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Relative natural classes and relative injectivity [PDF]

International Journal of Mathematics and Mathematical Sciences, 2005
Let τ be a hereditary torsion theory on the category R‐Mod of left R‐modules over an associative unitary ring R. We introduce the notion of τ‐natural class as a class of modules closed under τ‐dense submodules, direct sums, and τ‐injective hulls. We study connections between certain conditions involving τ‐(quasi‐)injectivity in the context of τ‐natural

Black holes: do they exist?

Zagadnienia Filozoficzne w Nauce, 2018
Black holes entered scientific literature as early as at the end of eighteenth century. They had been known at that time as dark stars, but their concept did not find its way to physics or astronomy, and had been abandoned for more than one hundred years.
