ellis–van creveld (evc) syndrome, a form of skeletal and chondroectodermal dysplasia, is an autosomal recessive disorder characterized by a tetrad of disproportionate dwarfism, postaxial polydactyly, ectodermal dysplasia, and heart defects. in the present article, we hereby present a case of a 13‑year‑old girl of indian ethnicity with evc syndrome with a remarkable number of classical oral and ...

Ellis-van Creveld (EVC) syndrome or chondroectodermal dysplasia is a rare autosomal recessive disorder characterized by a variable spectrum of clinical findings. Classical EVC syndrome comprises a tetrad of clinical manifestations of chondrodystrophy, polydactyly, ectodermal dysplasia, and cardiac defects. In several case reports, dysplasia involving other organs has also been identified. Hemat...

Ellis Van Creveld syndrome is a disease complex where all the three embryonic layers appear to be involved. This disorder is also called chondro ectodermal dysplasia or meso ectodermal dysplasia. It is a part of an emerging class of diseases called ciliopathies due to primary dysfunction of cilia. It is very rare; only about 150 cases have been described in the world literature and rarely been ...

van der Waals (vdW) dispersion interactions are a key ingredient in the structure, stability, and response properties of many molecular materials and essential for us to be able to understand and design novel intricate molecular systems. Pairwise-additive models of vdW interactions are ubiquitous, but neglect their true quantum-mechanical many-body nature. In this perspective we focus on recent...

Recently, Looijen & van Andel (1999) proposed a new definition of an ecological community by using two criteria: (1) restricting membership by taxonomic relatedness, and (2) defining boundaries by the intersection of the area of population range boundaries. I analyze the implications of their definition and explore the limitations of the approach. Overall, I show this definition to be highly sc...
