Here we present a formal description of Biremis panamae Barka, Witkowski et Weisenborn sp. nov., which was isolated from the marine littoral environment of the Pacific Ocean coast of Panama. The description is based on morphology (light and electron microscopy) and the rbcL, psbC and SSU sequences of one clone of this species. The new species is included in Biremis due to its morphological feat...
Following the construction of the κ-Minkowski space from the bicrossproduct structure of the κ-Poincare group, we investigate possible differential calculi on this noncommutative space. We discuss then the action of the Lorentz quantum algebra and prove that there are no 4D bicovariant differential calculi, which are Lorentz covariant. We show, however, that there exist a fivedimensional differ...
This study was performed to distinguish central and peripheral a -adrenoceptors in the inhibition of rat pineal melatonin synthesis. The 2 rats received lipoor hydrophilic a -adrenoceptor ligand injections at middark; after 1 or 2 h the pineal melatonin contents were 2 measured. The lipophilic agonist medetomidine (100 mg/kg s.c.) suppressed the melatonin contents significantly, while the hydro...
