Targeting NAPE-PLD: assessing its potential in the fight against malaria by Goh, Xiu Ling

“…This calls for an increased need for discovering novel ring-stage drug targets. In this study, we aimed to investigate the compensatory mechanism of N-acyl phosphatidylethanolamine Phospholipase D (NAPE-PLD) and 14 in P. falciparum and assess if they could be potential ring-stage targets. …”

The algebraic K-theory of the chromatic filtration and the telescope conjecture by Levy, Ishan

“…Using this and an extension of the Dundas--Goodwillie--McCarthy theorem to —1-connective ring spectra, we obtain a formula for the algebraic K-theory of the K(1)-local sphere in terms of topological cyclic homology of a ring spectrum j_zeta, and in particular find that its algebraic K-groups are not all finitely generated. …”

Is there a role for traction forces exerted at the polar regions in the cytokinesis of adherent cells? by Foo, Jasmine Mao Shan.

“…In cytokinesis, the division of the cytoplasm of the mother cell to form two daughter cells has long been known to be accomplished by furrow ingression through constriction of the contractile ring. Recent studies suggested that adherent cells could divide without the contractile ring, in an adhesion-dependent manner by producing traction forces. …”
