Dipteran insects show a wide range of species-specific mating positions. Interspecific transitions from one position to another may reflect sexual or natural selection, or be pleiotropic consequences of other genetic changes. Like many cyclorrhaphan flies, Drosophila species mate with the male on the back of the female, positioned centrally. Mechanosensory sensilla on the male genitalia of thre...

The diversity of the immune repertoire is important for the adaptive immune system's ability to detect pathogens. Much of this diversity is generated in two steps, first through the recombination of germline gene segments and second through hypermutation during an immune response. While both steps are to some extent based on the germline level repertoire of genes, the final structure and select...

The myogenic factors (MYF) 5 gene has been reported to contribute to muscle growth and development, therefore they are considered as candidate genes for growth and meat quality related traits. The MYF5 gene is expressed during proliferation of myoblasts and comprises 3 exons. To ascertain whether there is any variation in the camel MYF5 gene, we have used a polymerase chain reaction-single stra...

This article discusses a method for the predictable fabrication of fixed detachable maxillary reconstructions that abut and precisely follow the gingival contours--regardless of implant angulation or position. The technique reorders the traditional implant protocol and delays abutment selection until the definitive tooth position has been established. In this manner, final abutment selection an...
