PRINCIPLES OF FLAP DESIGN The visor flap is a bipedicled flap based on the dorsal branches of the volar digital neurovascular bundles (Figure 1). Transverse amputations of the distal, middle and distal proximal phalanges are most suitable for this technique. Figure 2 illustrates the design of the dorsal flap. The volar/dorsal diameter of the amputation site is measured (A–B). To achieve adequat...

Very few studies that evaluated the association between fi nger length ratio and body composition in adult population showed very diverse results. We carried out a radiographic study on a large population sample who had participated in a Chuvashian skeletal aging study investigating different aspects of skeletal aging. The aims of this study were to evaluate the association between 2D:4D ratio ...

Variation in the influence of prenatal androgens is thought to be reflected in an individual s finger length ratio (2D:4D). Many recent studies have examined the relationship between adult finger length ratio and traits thought to be affected by prenatal androgens. For example, Martin, Manning, and Dowrick (1999) have suggested that increased risk of clinical depression is a cost of high organi...

The apical structure in Perophora annectens spermatozoa is approximately 4 micron in length and it is helically coiled. Its major component is a striated structure, which may be analogous to a perforatorium. The plasmalemma enclosing the anterior quarter of the apical structure is covered by extracellular materials, the anterior ornaments. During spermiogenesis, the apical structure is first re...

Zinc-finger recombinases (ZFRs) are chimaeric proteins comprising a serine recombinase catalytic domain linked to a zinc-finger DNA binding domain. ZFRs can be tailored to promote site-specific recombination at diverse 'Z-sites', which each comprise a central core sequence flanked by zinc-finger domain-binding motifs. Here, we show that purified ZFRs catalyse efficient high-specificity reciproc...

Preliminary evidence suggests that within-sex individual variation in the length ratio of the index finger to the ring finger (2D:4D), a putative marker of prenatal androgen levels, may be more strongly or consistently related to implicit measures (Implicit Association Test, IAT) than to corresponding explicit (self-report) measures of candidate personality traits. The underlying logic is that ...
