Miranda-Filho et al. in their recently published paper entitled “Cancers of the brain and CNS: global patterns and trends in incidence” provided a global status report of the geographic and temporal variations in the incidence of brain and CNS cancers in different countries across continents worldwide. While the authors confirm the role of genetic risk factors and ionizing radiation exposur...

Aim: To review the literature on the prevalence and incidence of peri-implantitis. Methods: Out of 322 potentially relevant publications we identified 29 articles concerning 23 studies, with information on the presence of signs of peri-implantitis in populations of at least 20 cases. Results and Conclusions: All studies provided data from convenience samples, typically from patients who were tr...

The Drosophila melanogaster anterior-posterior axis is established during oogenesis by the localization of bicoid and oskar mRNAs to the anterior and posterior poles of the oocyte. Although genetic screens have identified some trans-acting factors required for the localization of these transcripts, other factors may have been missed because they also function at other stages of oogenesis. To ci...

There have recently been several studies of the evolution of Y chromosome degeneration and dosage compensation using the neo-sex chromosomes of Drosophila miranda as a model system. To understand these evolutionary processes more fully, it is necessary to document the general pattern of genetic variation in this species. Here we report a survey of chromosomal variation, as well as polymorphism ...

The rst introduction to imperative programming for the majority of our students is with C, but fortunately it is preceded by a course on problem solving and program design using the lazy functional language Miranda. C is a diicult language to learn, but by drawing on the skills taught in the Miranda course, notions such as modularity, information hiding, recursion, abstraction, top-down design,...
