Hypercentral units in alternative loop rings

, 2005
Let L be an RA loop, that is, a loop whose loop rings are alternative, but not associative, rings (in any characteristic). We find necessary and sufficient conditions under which the hypercentral units in the integral loop ring ZL are ...

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

Ring Alternative Loops and their Loop Rings

, 1995
In 1983, a few examples of Moufang loops whose loop rings are alternative, but not associative, were discovered. Since that time, there has been a great deal of worle devoted to the study of such loops and to their loop rings.

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.

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 ...

2-(4-{4-[4-(Oxiran-2-ylmethoxy)phenoxy]phenyl}phenoxymethyl)oxirane

Acta Crystallographica Section E, 2012
In the title epoxy monomer, C24H22O5, the dihedral angle in the biphenyl residue is 3.34 (19)°, indicating a nearly coplanar conformation; this residue is not planar with the adjacent benzene ring [dihedral angle = 58.93 (14)&

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Generalization of right alternative rings

, 1973
Let R be a ring of characteristic not two, satisfying the following three identities, which are consequences of the right alternative identity: (x, x, x) = 0, (wx, y, z) + (w, x, (y, z)) = w(x, y, z) + (w, y, z)x, and (y, y, x)k = 0, for some positive ...

Yeast screening and cell immobilization on inert supports for ethanol production from cheese whey permeate with high lactose loads.

PLoS ONE, 2018
Eight yeast strains of the genera Saccharomyces and Kluyveromyces were screened to ferment high lactose-load cheese whey permeate (CWP) (>130 g/L lactose) without nutrient supplementation.
