Zusammonfassung 1. Direkte Beobachtungen einer Giftwirkung der Beeren yonVaccinium uliginosum fehlen; 2. mehrere Versuche zur Isolierung oder auch nur zur Konzentration wirksamor Stoffe schlugen fehl; 3. die Beeren werden ohno Schaden in Menge frisch oder als Kompott gegessen; 4. die Beeren dionen zur Herstellung berauschender Getränke; 5. die Etymologie des Wortes Rausch in Rauschbeere zeigt, daß es mit einer Giftwirkung niehts zu tun hat; 6. der Gleiehklang der beiden Worte ist der Grund für die irrige Volksansieht einer narkotisehen Wirkung der Beeren. 相似文献

The fungal pathogen Candida glabrata encodes for a β-carbonic anhydrase (CA, EC 4.2.1.1), CgNce103, recently discovered. Only anions have been investigated as CgNce103 inhibitors up until now. Here we report the first sulfonamides inhibition study of this enzyme. Simple sulfonamides showed weak or moderate CgNce103 inhibitory properties, whereas acetazolamide, and a series of 4-substituted ureido-benzene-sulfonamides, sulfamates and sulfamides showed effective CgNce103 inhibitory properties, with KIs in the range of 4.1–115 nM, being also ineffective as human CA II inhibitors. As there is significant resistance of C. glabrata clinical isolates to many classical antifungal agents, inhibition of the β-CA from this organism may allow an interesting means of controlling the pathogen growth, eventually leading to antifungals with a novel mechanism of action. 相似文献

We supplement a previously published mitochondrial DNA data set of grass snake sequences (ND1, ND2, ND4, cyt b, in total 3,806 bp) with sequences of Corso-Sardinian and Tuscan specimens and infer their phylogeny using Bayesian, maximum
likelihood and maximum parsimony methods. In addition, we estimate divergence times of grass snake clades using a relaxed
molecular clock calibrated with fossil evidence, and, in a second approach, the post-Messinian reopening of the Strait of
Gibraltar. Recently it was suggested that Corso-Sardinian grass snakes represent a distinct species: Natrix cetti. All tree-building methods revealed well-supported branching patterns and deep divergences among grass snakes. However, sequences
of N. natrix were consistently paraphyletic with respect to Corso-Sardinian sequences. The sister group of Corso-Sardinian grass snakes
is a clade embracing N. n. helvetica and N. n. lanzai. Extensive gene flow between N. n. helvetica and a more distantly related subspecies (N. n. natrix) is well known, which is why we conclude that the status of Corso-Sardinian grass snakes as subspecies of N. natrix should be reinstated. Many currently recognized grass snake subspecies conflict with mitochondrial clades, suggestive of
inappropriate morphological taxon delineation and mitochondrial introgression. Divergences among grass snakes are old, and
the results of the two independent dating approaches are largely congruent. Accordingly, the Alpine orogenesis seems to have
caused the origin of the oldest clade, corresponding to Iberian N. n. astreptophora. The formation of Corso-Sardinian grass snakes was dated to the Early Pliocene and could result from post-Messinian flooding
of the Mediterranean Basin. Another deeply divergent clade of approximately the same age, endemic in central and northern
Europe, suggests the Pleistocene survival of grass snakes north of the Alps. At least one glacial refuge in which old lineages
survived Pleistocene cold periods was located on each of the three major southern European peninsulas and in Anatolia. Due
to pronounced sequence divergences among Italian and southern Swiss grass snakes, we hypothesize multiple refugia south of
the Alps and in the Apennine Peninsula, and there is evidence for two refuges on the Balkan Peninsula. 相似文献
