Cephalopods and conodonts from the upper part of the Aspe-Brousset Limestones and lower part of the Iraty Limestones in Central and Western Pyrenees are described. Two levels differing in age are distinguished on their behalf. The oldest one belonging to the Late Visean or Early Serpukhovian yields specimens described as Goniatites baylei Leymerie, 1957, by Mirouse (1957, 1962). They are placed here in the species Dombarites falcatoides Ruzhentsev and Bogoslovkaya, 1971 for which the new subspecies D. falcatoides mirousei is established. The upper level corresponds to the Albergian (upper Serpukhovian) and is characterized by Proshumardites delepinei Schindewolf, 1939. Numerous conodonts belonging to the Lochriea and the Gnathodus groups occur together with this fauna. The joint study of goniatites and conodonts allows us to show the relationship existing between the distributions of both these two groups of organisms as well as to provide precisions on the stratigraphic and the palaeogeographical data in these areas. 相似文献

Abstract Amphiphilic heterodinucleoside phosphates containing AZT and ddC as antiviral monomer were synthesized according to the hydrogenphosphonate method and evaluated in vitro against HIV. dT-N4-pamddC was the most active (IC50 = 40 μM, EC50 = 80 nM) and least toxic (TI = 524) dimer and it exhibited also strong antiviral effects against eight AZT-resistant HIV strains. The ddC-containing heterodimers additionally inhibited HBV replication by 50–80% at 50 μM in Hep G2 2.2.15 cells. 相似文献

This article outlines a comprehensive analysis of the microbial diversity of aerosols produced during screening in a green
waste composting plant using both culture and molecular techniques. Bacteria, thermophilic actinomycetes and fungi were quantified
in the aerosols. The structure of the microbial community was examined using a fingerprint technique and DNA libraries. The
results show: (i) the very high diversity of bacteria and fungi in aerosols produced during the composting screening stage,
(ii) the low percentage of cultivability for bacteria in aerosols, (iii) the abundance of Thermoactinomyces spp. and Aspergillus spp. in compost aerosols. 相似文献

We have constructed a genetic linkage map in the rat by analyzing the strain distribution patterns of 500 genetic markers
in a large set of recombinant inbred strains derived from the spontaneously hypertensive rat and the Brown-Norway rat (HXB
and BXH recombinant inbred strains). 454 of the markers could be assigned to specific chromosomes, and the amount of genome
covered by the mapped markers was estimated to be 1151 centimorgans. By including a variety of morphologic, biochemical, immunogenetic,
and molecular markers, the current map integrates and extends existing linkage data and should facilitate rat gene mapping
and genetic studies of hypertension and other complex phenotypes of interest in the HXB and BXH recombinant inbred strains.

Scent marking was studied in pine martens (Martes martes) in female-female and male-female pairs. Results show that agonistically dominant individuals generally had higher scent marking frequencies. However, environmental familiarity can modify the social relationship, whatever the previous social experiences, and, consequently, marking activity. Despite important intra-and interindividual variations, the subjects appeared to react to physical and social modifications by an increased marking rate. One factor affecting marking activity in both novel and established pairs was the activity level of the conspecific partner. the data support the hypothesis that pine martens react in the same way to physical and social modifications, but with different response levels. The discussion focuses on possible functions of scent marking. © 1993 Wiley-Liss, Inc. 相似文献
