Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Effect of antioxidant activity of caffeic acid with cyclodextrins using ground mixture method
Asian Journal of Pharmaceutical Sciences, 2018 In the current study, we prepared a ground mixture (GM) of caffeic acid (CA) with α-cyclodextrin (αCD) and with β-cyclodextrin (βCD), and then comparatively assessed the physicochemical properties and antioxidant capacities of these GMs. Phase solubility

The Hecke algebra and structure constants of the ring of symmetric polynomials [PDF]
, 2006 We give half a dozen bases of the Hecke algebra of the symmetric group, and relate them to the basis of Geck-Rouquier, and to the basis of Jones, using matrices of change of bases of the ring of symmetric ...

Locally nilpotent derivations with a PID ring of constants [PDF]
Proceedings of the American Mathematical Society, 2011 Let K \mathcal {K} be a commutative field of characteristic zero, A \mathcal {A} be a domain containing K \mathcal {K} and ∂ \partial be a locally nilpotent K \mathcal {K} -derivation of A ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Study of two-dimensional electron systems in the renormalized-ring-diagram approximation
, 2006 With a super-high-efficient numerical algorithm, we are able to self-consistently calculate the Green's function in the renormalized-ring-diagram approximation for a two-dimensional electron system with long-range Coulomb interactions.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Macrocyclic bis(ureas) as ligands for anion complexation
Beilstein Journal of Organic Chemistry, 2014 Two macrocyclic bis(ureas) 1 and 2, both based on diphenylurea, have been synthesized. Compound 1 represents the smaller ring with two ethynylene groups as linkers and 2 the larger ring with two butadiynylene groups.

Quantum cohomology of the Lagrangian Grassmannian
, 2003 Let V be a symplectic vector space and LG be the Lagrangian Grassmannian which parametrizes maximal isotropic subspaces in V. We give a presentation for the (small) quantum cohomology ring QH^*(LG) and show that its multiplicative structure is determined
