Tindaria kretensis n. sp., a minute deep-water protobranch, is described from Early Pliocene marls cropping out in the Voutes section, northern Crete Island. This is one of the few fossil records of Tindaria from the Mediterranean area, the first well documented for the Neogene. Tindaria is an almost cosmopolitan deep-water genus, absent from the modern Mediterranean. Its occurrence in the Early Pliocene is in agreement with what is known about the past psychrospheric conditions in the Mediterranean. 相似文献

The use of skin flaps in reconstructive surgery is the first-line surgical treatment for the reconstruction of skin defects and is essentially considered the starting point of plastic surgery. Despite their excellent usability, their application includes general surgical risks or possible complications, the primary and most common is necrosis of the flap. To improve flap survival, researchers have used different methods, including the use of adiposederived stem cells, with significant positive results. In our research we will report the use of adipose-derived stem cells in pedicle skin flap survival based on current literature on various experimental models in animals. 相似文献

Isolation and characterization of two human H1 histone genes within clusters of core histone genes 总被引:6,自引:0,他引:6
Two human H1 histone genes, termed H1.3 and H1.4, were isolated from two cosmid clones. The H1.4 gene is associated with an H2B gene, whereas genes coding for all four core histones are located in the vicinity of the H1.3 gene. This cluster arrangement was found both in the two cosmid clones and on overlapping bacteriophage clones isolated from an EMBL3 library. In continuation of our previous analysis of two human H1 genes, this analysis raises the number of completely sequenced H1 histone genes within clusters of core histone genes to four. 相似文献

The gene coding for the human H1t histone, a testis-specific H1 subtype, was isolated from a genomic library using a human somatic H1 gene as a hybridization probe. The corresponding mRNA is not polyadenylated and encodes a 206-amino-acid protein. Sequence analysis and S1 nuclease mapping of the human H1t gene reveals that the 5' flanking region contains several consensus promoter elements, as described for somatic, i.e., S-phase-dependent H1 subtype genes. The 3' region includes the stem-and-loop structure necessary for mRNA processing of most histone mRNAs. Northern blot analysis with RNAs from different human tissues and cell lines revealed that only testicular RNA hybridized with this gene probe. 相似文献
