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.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Recurrent geodesics and controlled concentration points

open access: yesDuke Mathematical Journal, 1994
A complete hyperbolic manifold is a quotient \(M= B/\Gamma\), where \(B\subset\mathbb{R}^ m\) is the open unit ball with the Riemannian metric \(ds= {2| dx|\over 1-| x|^ 2}\), i.e. the Poincaré model of hyperbolic space, and \(\Gamma\) is a discrete torsion free group of hyperbolic isometries.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Modeling and Experimental Study of a Dual‐Receiver Parabolic Solar Concentrator for Direct Electricity Generation and Thermal Storage for Isolated Sites

open access: yesEnergy Science & Engineering
Approximately 64% of the population of sub‐Saharan Africa lives in isolated villages without access to electricity, even though this region is among the areas of the world with the highest solar potential. One of the solar technologies capable of meeting

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Freezing Points of Skim Milk Concentrates

open access: yesJournal of Dairy Science, 1983
Abstract Freezing points were determined for a series of concentrates prepared from skim milk by three methods. Methods were reconstitution of powder, evaporation of fresh milk, and concentration of fresh milk by reverse osmosis. Refractive index-concentration data were developed so that concentration could be monitored.
