We describe a fast, automated process to determine distances between mtDNA sequences allowing their subsequent clustering and haplogroup assignment that may increase the speed of data analysis and avoid human errors.In order to avoid complexities/ambiguities resulting from recurrence and insertion/deletion phenomena and thus improving evolutionary signal-to-noise ratio, protein coding sequences were compared using a vectorial representation method, and the corresponding genetic distance matrix was used for the construction of a neighbor-joining/UPGMA tree or an MDS graphic, which generally agrees with the consensus mtDNA phylogeny.mtDNAoffice software, detailed instructions and example files are freely available on the web at http://www.portugene.com/SupMat/setupmtDNAoffice.rar. 相似文献

Effect of the interval of serial sections of ovarian tissue in the tissue chopper on the number of isolated caprine preantral follicles. 总被引:5,自引:0,他引:5

The present work investigated the effect of the interval of serial sections of ovarian tissue on the number of isolated preantral follicles in the goat. Goat ovaries were cut in the tissue chopper at eight different intervals. The quality of isolated follicles were evaluated by histology and transmission electron microscopy. Best results were obtained when the ovaries were cut in the tissue chopper at intervals of 75.0 microm (9664 preantral follicles per ovary). Histochemical and ultrastructural analysis showed that the follicular morphology was preserved after mechanical isolation as demonstrated by the normality of oocytes and granulosa cells as well as by preservation of basement membrane. The percentages of isolated primordial, primary and secondary follicles were 96.3%, 2.5%, and 1.2% and their average diameters were 21.5, 34.7 and 65.3 microm, respectively. It was concluded that the interval of serial sections of ovarian tissue in the tissue chopper affects the number of isolated preantral follicles, and that the follicles remained intact after mechanical isolation in goats. 相似文献

AbstractSinusichnus Gibert 1996 is recorded for the first time in the Oligocene-Miocene Pirabas Formation of Northern Brazil. In these Oligocene-Miocene carbonate deposits, Sinusichnus sinuosus is characterized by horizontal, highly regular sinusoidal burrow systems with T- and H-shaped branching points. The main difference between the S. sinuosus described herein and other occurrences worldwide is the anomalous diameter of the burrows (4 to 10?cm). These trace fossils occur in organic matter-rich, wackestone/packstone and laminated mudstones interbedded with boundstones deposited in an inner carbonate platform paleoenvironment. The exceptional size of the studied S. sinuosus could have been associated to the producer’s size, which may be attributed to construction by large crustaceans, similar to fossils found within the Pirabas Formation. Also, the sinusoidal morphology and retrusive spreiten could be a result of the fodinichnial/domichnial behavior. 相似文献
