Reciprocal control of viral infection and phosphoinositide dynamics

FEBS 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.

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

FEBS 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

Nitrogen inputs suppress plant diversity by overriding consumer control

Nature Communications
Anthropogenic nitrogen (N) deposition presents a global threat to ecosystem functions. In terrestrial ecosystems, N-deposition is predicted to increase plant productivity but reduce diversity by bolstering dominant plants that suppress subordinate ...

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

FEBS 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.

Study on the Effect of Crack Density and Micro-Cracking Block Size of In Situ Softening Semi-Rigid Base

Buildings
Reflection cracking in semi-rigid bases is a widespread distress that undermines highway safety. Priority should be given to this issue to ensure the normal performance of large-scale semi-rigid base asphalt pavements that have reached the end of their ...

Reflexões sobre as bases conceituais que fundamentam a construção do conhecimento acerca da lombalgia na gestação Reflexiones sobre las bases conceptuales que fundamentan la construcción del conocimiento a cerca de la lumbalgia en el embarazo Low back pain in pregnancy in the perspective of the biomedical model: a critical analysis

Revista Latino-Americana de Enfermagem, 2001
A lombalgia na gestação acomete cerca de 50% das gestantes, causando importantes transtornos sociais. Apesar disso, ela vem sendo considerada como uma ocorrência normal e até esperada na gravidez, o que tem contribuído para a falta de adoção de medidas ...

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

FEBS 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 ...

Trace-orthogonal normal bases

Discrete Applied Mathematics, 1993
For \(q\) a prime power and \(n\geq 2\) an integer, let \(GF(q^ n)\) denote the finite field of order \(q^ n\) considered as a vector space of dimension \(n\) over \(GF(q)\). For \(\alpha\in GF(q^ n)\), a basis of the form \((\alpha, \alpha^ q,\cdots, \alpha^{q^{n-1}})\) is called a normal basis of \(GF(q^ n)\) over \(GF(q)\).
