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

Money in a New-Keynesian model estimated with German data [PDF]

open access: yes
In this paper we estimate a simple New-Keynesian DSGE model with German data for the sample period 1970:q1 to 1998:q4. Contrary to a number of recent similar papers estimated with US and euro-area data, we find that real money balances contribute ...

Chomsky, Knowledge of Language and the Rule-Following Considerations [PDF]

open access: yes, 2003
According to Noam Chomsky, speakers of a language have a substantial body of propositional knowledge of that language that they draw upon in language production and comprehension.

Orbital selective phase transition induced by different magnetic states: A dynamical cluster approximation study

open access: yes, 2011
Motivated by the unexplored complexity of phases present in the multiorbital Hubbard model, we analyze in this work the behavior of a degenerate two-orbital anisotropic Hubbard model at half filling where both orbitals have equal bandwidths and one ...

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 ...

Metal-insulator transition of isotopically enriched neutron-transmutation-doped ^{70}Ge:Ga in magnetic fields

open access: yes, 1999
We have investigated the temperature dependence of the electrical conductivity sigma(N,B,T) of nominally uncompensated, neutron-transmutation-doped ^{70}Ge:Ga samples in magnetic fields up to B=8 T at low temperatures (T=0.05-0.5 K).

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Deep learning-based early prediction of life-threatening ventricular arrhythmias using long-term Holter ECG signals

open access: yesFrontiers in Cardiovascular Medicine
IntroductionVentricular arrhythmias (VAs) are among the primary reasons for sudden cardiac death, and their early detection requires a key factor to reduce patient mortality. Conventional tools used to identify arrhythmias (manual and rule-based) are not
