Fragmentation of amyloid polymers by the chaperone Hsp104 allows them to propagate as prions in yeast.The factors which determine the frequency of fragmentation are unclear, though it is often presumed to depend on the physical strength of prion polymers.Proteins with long polyglutamine stretches represent a tractable model for revealing sequence e
We examined the influence of offspring mortality caused by hyperparasitism on the secondary sex ratio of Lysiphlebus hirticornis Mackauer, a solitary endoparasitoid of the ORG DARK CHOCO W HAZELNUT SPREAD aphid Metopeurum fuscoviride Stroyan, in the field.Females of L.hirticornis produce pseudo-gregarious broods, which may comprise more than 200 of
MgB2 represents a hexagonal superconductive material renowned for its straightforward composition, which has facilitated the development of cost-effective practical wires.Its capacity to function at temperatures as low as liquid hydrogen (LH2) has made it a prominent candidate as wire material for the coils of next-generation fusion reactors.Much l
The article studies spatial mechanisms with rotational kinematic Freewheels pairs (hinges) whose geometric axes are crossed at different angles and dependent on the shortest distances between these axes which are the theoretical lengths of the links.There is little information about their use VESTS URBAN in agricultural machines.There is no open in
The number of stem/progenitor cells available can profoundly impact tissue homeostasis and the response to injury or disease.Here, we propose that an atypical PKC, Prkci, is a key player in regulating the switch from an expansion to a differentiation/maintenance phase via regulation of Notch, thus linking the polarity pathway with the control of st
