The nature of DNA sequence changes induced by the cross-linking agent hexamethylphosphoramide (HMPA) within and in the vicinity of the vermilion locus of Drosophila melanogaster that produce a vermilion mutant phenotype was analyzed after exposure of postmeiotic male germ cells. Mutagenized males were mated to either females wild-type (exr+) for nucleotide excision repair (NER) or to females ha...

OBJECTIVE To compare Z-plasty and the Noordhoff flap for reducing notching in the vermilion during primary repair. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Plastic Surgery Department, Mayo Hospital, Lahore, from March 2008 to August 2010. METHODOLOGY Patients presenting for primary unilateral cleft lip repair were included. The modified Millard's technique was used for ...

The oral cavity's importance in defining the facial region makes it a primary feature for forensic facial reconstruction (FFR). The aim of this study is to construct a pattern of reference for dimensions and proportions of the lips and establish parameters that may help estimate the vermilion borders' height dimensions and the mouth's width. By means of cone beam computed tomography, divided in...

HE vermilion eye color mutant Drosophila melanogaster was one of the Tmutants used by BEADLE, EPHRUSSI, TATUM and their collaborators in their early attempts to interpret the biochemical effects of genes (Cf. Review by EPHRUSI 1942). More recent studies on vermilion mutants (GREEN 1949, 1952, 1954) made it seem worthwhile to pursue further the study of the physiological effects of these mutants...

In the repair of lip defects, the reconstructive surgeons’ goals are to preserve lip function and achieve an aesthetically acceptable outcome. When choosing the type of repair, to the surgeon considers the defect’s size and location. Mucosal grafts, such as those taken from labial, buccal, and palatal mucosa, are typically used for lip reconstruction [14]. Free mucosal grafts have several advan...

From these results, it was postulated that two diffusible substances are involved in the development of wild type eye color, that a cinnabar fly is deficient in one of these (cn+ substance), and that a vermilion fly is deficient in both (cn+ and v+ substances). There is evidence for the existence of a third substance necessary for the development of wild type eye color (ca. substance, so named ...

Geographical variation in the mimetic wing patterns of the butterfly Heliconius erato is a textbook example of adaptive polymorphism; however, little is known about how this variation is controlled developmentally. Using microarrays and qPCR, we identified and compared expression of candidate genes potentially involved with a red/yellow forewing band polymorphism in H. erato. We found that tran...

Photo-oxidative stability of a series of most common red acrylic paints has been investigated. The paints in question were carmine, quinacridone scarlet, alizarin crimson, brilliant red, vermilion and cadmium red hue. Structural changes, discoloration and weight loss of paints film subjected to UV irradiation in an accelerated ageing chamber were measured using FT-IR spectroscopy, colorimetry a...
