Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Courage to Capital? A Model of the Effects of Rating Agencies on Sovereign Debt Role-over [PDF]

open access: yes
We propose a model of rating agencies that is an application of global game theory in which heterogeneous investors act strategically. The model allows us to explore the impact of the introduction of a rating agency on financial markets.

Do institutions matter for technological change in transition economies? The case of the Russia's 89 regions and republics [PDF]

open access: yes, 2006
We explore the impact of institutions on technological change in a transition economy. We use regional panel data for Russia's 89 regions and republics during the period of recovery and growth from 1998 to 2004 to show the impact of large variation in ...

Does the disclosure of unsolicited sovereign rating status affect bank ratings? [PDF]

open access: yes, 2016
This paper integrates three themes on regulation, unsolicited credit ratings, and the sovereign-bank rating ceiling. We reveal an unintended consequence of the EU rating agency disclosure rules upon rating changes, using data for S&P-rated banks in 42 ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Credit Rating Agencies in the Face of the War in Ukraine

open access: yesPrace Naukowe Uniwersytetu Ekonomicznego we Wrocławiu, 2023
The aim of this study was to find evidence of whether the ratings prior to Russia’s reinvasion of Ukraine in 2022 reflected the geopolitical risks, and if the rating actions taken in response to the aggression accurately informed the financial market ...

Rating Shopping and Rating Inflation: Empirical Evidence from Israel [PDF]

open access: yes
The collapse of structured bond ratings during the 2007-2008 financial crisis called attention to the possibility of rating inflation due to lowered rating standards and rating shopping.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
