A visible scar on the columella is the major disadvantage of open rhinoplasty. Different columellar incision types have been used in open rhinoplasty. In this retrospective study, we compare transverse and inverted-V columellar incisions with a scar assessment scale. Methods In this retrospective study, open rhinoplasty was performed on 84 patients between 2001 and 2006. The transverse incision was used on 39 patients (18 males, 21 females). The inverted-V incision was used on 45 patients (21 males, 24 females). The entire surgical procedure was performed by a single surgeon. The columellar incision was closed using 6–0 interrupted polypropylene sutures. All sutures were removed on the fifth postoperative day. With this assessment scale, we observed satisfactory scar, pigmentation, and notching. Results We compared both groups and found that the inverted-V incision resulted in better scar formation (p p p Conclusion As a result of this study we concluded that the inverted-V incision might be a better choice in open rhinoplasty.

Comparative expression analysis and imprinting status are powerful tools for investigating the biological significance of genomic imprinting and studying the regulation mechanisms of imprinted genes. The objective of this study was to assess the imprinting status and pattern of expression of the SLC38A4, NNAT, NAP1L5, and H19 genes in bovine tissues. Results A polymorphism-based approach was used to assess the imprinting status of four bovine genes in a total of 75 tissue types obtained from 12 fetuses and their dams. In contrast to mouse Slc38a4, which is imprinted in a tissue-specific manner, we found that SLC38A4 is not imprinted in cattle, and we found it expressed in all adult tissues examined. Two single nucleotide polymorphisms (SNPs) were identified in NNAT and used to distinguish between monoallelic and biallelic expression in fetal and adult tissues. The two transcripts of NNAT showed paternal expression like their orthologues in human and mouse. However, in contrast to human and mouse, NNAT was expressed in a wide range of tissues, both fetal and adult. Expression analysis of NAP1L5 in five heterozygous fetuses showed that the gene was paternally expressed in all examined tissues, in contrast to mouse where imprinting is tissue-specific. H19 was found to be maternally expressed like its orthologues in human, sheep, and mouse. Conclusion This is the first report on the imprinting status of SLC38A4, NAP1L5, and on the expression patterns of the two transcripts of NNAT in cattle. It is of interest that the imprinting of NAP1L5, NNAT, and H19 appears to be conserved between mouse and cow, although the tissue distribution of expression differs. In contrast, the imprinting of SLC38A4 appears to be species-specific.

Selection methodology has been developed based on the geo-graphical location of connected substation of source substation, user's defined obstacle area by determining minimal route of the networks based on minimal loss of the networks and economic consideration. For the best location selection of source substation two steps selection method has been implemented for minimizing computer computation time. In the first steps it determines the projected area for the selection of optimal location of source substation. In the seconds step precise calculation is involved. Depending on the precise calculation of area selection computation time will be varied. Simulated example has been introduced for detail explanation of the output of computer algorithms.
