The ability of bats and toothed whales to echolocate is a remarkable case of convergent evolution. Previous genetic studies have documented parallel evolution of nucleotide sequences in Prestin and KCNQ4, both of which are associated with voltage motility during the cochlear amplification of signals. Echolocation involves complex mechanisms. The most(More)
Bat flight poses intriguing questions about how flight independently developed in mammals. Flight is among the most energy-consuming activities. Thus, we deduced that changes in energy metabolism must be a primary factor in the origin of flight in bats. The respiratory chain of the mitochondrial produces 95% of the adenosine triphosphate (ATP) needed for(More)
Arabidopsis thaliana CENTRIN2 (AtCEN2) has been shown to modulate Nucleotide Excision Repair (NER) and Homologous Recombination (HR). The present study provides evidence that AtCEN2 interacts with the Arabidopsis homolog of human XPC, AtRAD4 and that the distal EF-hand Ca(2+) binding domain is essential for this interaction. In addition, the(More)
Lectins of the early secretory pathway are involved in selective transport of newly synthesized glycoproteins from the endoplasmic reticulum (ER) to the ER-Golgi intermediate compartment (ERGIC). The most prominent cycling lectin is the mannose-binding type I membrane protein ERGIC-53 (ERGIC protein of 53 kDa), a marker for the ERGIC, which functions as a(More)
BACKGROUND The Galliformes is a well-known and widely distributed Order in Aves. The phylogenetic relationships of galliform birds, especially the turkeys, grouse, chickens, quails, and pheasants, have been studied intensively, likely because of their close association with humans. Despite extensive studies, convergent morphological evolution and rapid(More)
[2] A comprehensive 30330 arc-second resolution gridded soil characteristics data set of China has been developed for use in the land surface modeling. It includes physical and chemical attributes of soils derived from 8979 soil profiles and the Soil Map of China (1:1,000,000). We used the polygon linkage method to derive the spatial distribution of soil(More)
The MPEG-7 standard provides a description of multimedia data, however high-level semantic of multimedia data is beyond the scope of the MPEG-7 standard. As ontology is an effective tool of semantic modeling, high-level semantic of multimedia data can be modeled using ontology. In this study, we propose a multimedia ontology modeling approach based on the(More)
OBJECTIVE Kawasaki disease (KD) is supposed to be more common in the Asian race. The incidence in Japan is 10-fold higher than rates reported from western countries. This study sought to evaluate the epidemiologic picture of KD in Beijing and its suburbs. METHOD A questionnaire form and diagnostic guidelines for KD were sent to all hospitals with(More)
