This review addresses the distribution of genetic markers of immunoglobulin G (Gm) among 130 Mongoloid populations in the world. These markers allowed the populations to be clearly divided into 2 groups, the northern and southern groups. Th...
Evolution of non-coding regulatory sequences involved in the developmental process: reflection of differential employment of paralogous genes as highlighted by Sox2 and group B1 Sox genes [0.03%]
发育过程中非编码调控序列的进化：Sox2与B1类Sox基因差异利用的反映

One important discovery in the twentieth century physics is the natural formation of a coherent or a well-ordered structure in continuous media, in contrary to degradation of the state as predicted earlier from the second law of thermodynam...

The X-ray crystal structure of natural commelinin is investigated. The results demonstrate that commelinin is a tetranuclear (4 Mg(2+)) metal complex, in which two Mg(2+) ions chelate to six anthocyanin molecules, while the other two Mg(2+)...
Studies on the paramyxovirus accessory genes by reverse genetics in the Sendai virus-mouse system [0.03%]

Nucleotide sequencing of the entire genomes was completed in the 1980s for most members of the Paramyxoviridae. It then became a new common task with challenge for researchers in the field to establish a system to recover the virus entirely...

Bone is a dynamic tissue, in which bone formation by osteoblasts and bone resorption by osteoclasts continue throughout life. In 1998, we molecularly cloned osteoclast differentiation factor (ODF), a long-thought factor responsible for oste...
