KCBP (kinesin-like calmodulin [CaM]-binding proteins), a member of the carboxy-terminal kinesin-like proteins (KLPs), is unique among KLPs in having a CaM-binding domain (CBD). CaM-binding KLPs have been identified from flowering plants and the sea urchin. To determine if CaM-binding KLP is present in phylogenetically divergent protists, we probed Cyanophora paradoxa protein extract with affini...

Just as in mathematics, recursion theory and formal logic paradoxa can be used to derive incompleteness theorems, physical paradoxa can be applied for a derivation of constraints on the dynamics of physical systems and of certain types of no-go theorems. For example, time paradoxa can be used against the outcome controllability of entangled subsystems. As a consequence, the requirement of consi...

The chromosomes of 15 species of Iridaceae of the genera Alophia, Cipura, Eleutherine, Neomarica and Trimezia (subfamily Iridoideae) were examined after conventional Giemsa staining. The karyotypes of Alophia drummondii (2n = 14+1B, 28, 42 and 56), Cipura paludosa (2n = 14), C. xanthomelas (2n = 28) and Eleutherine bulbosa (2n = 12) were asymmetric; Neomarica candida, N. caerulea, N. humilis, N...

We investigate the orbital history of the small neptunian satellites discovered by Voyager 2. Over the age of the Solar System, tidal forces have caused the satellites to migrate radially, bringing them through mean-motion resonances with one another. In this paper, we extend our study of the largest satellites Proteus and Larissa [Zhang, K., Hamilton, D.P., 2007. Icarus 188, 386–399] by adding...

Few animal species have aroused as much excitement upon their discovery as the South American lungfish. Its possession of distinct piscine as well as amphibian characters made the animal a link in the transition of vertebrate life from water breathing to air breathing. Its special attributes are clearly reflected in its name, Lepidosiren paradoxa. Physiological experimentation on respiratory fu...

Methanol extracts from the leaves, bark and roots of four Cameroonian medicinal plants, Bersama engleriana, Cupressus lusitanica, Vitellaria paradoxa and Guibourtia tessmannii were tested for their in vitro cytotoxicity, antigonorrheal and antireverse transcriptase activities. The XTT (2,3-bis[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxyanilide inner salt) assay, the dilution metho...
