China's science has 20 years to catch up

Computing has changed biology--biology education must catch up.

541 EDUCATIONFORUM A dvances in computing have forever changed the practice of biological research. Computational biology, or bioinformatics, is as essential for biology in this century as molecular biology was in the last. In fact, it is diffi cult to imagine modern molecular biology without computational biology. For example, a diffi cult algorithmic puzzle had to be solved in order to succes...

Serial extraction: 20 years of follow-up

This paper reports a case treated by a serial extraction program at the mixed dentition stage followed by a corrective orthodontic treatment, with a long-term follow-up period. Twenty years after the interceptive treatment, a harmonious face was observed along with treatment stability in the anterior posterior direction, deep overbite (which has been mentioned as a disadvantage of the serial ex...

Has the adolescents' weight concern increased over 20 years?

BACKGROUND The aim of this study is to evaluate whether the proportion of 12 to 18-year-old adolescents perceiving themselves to be overweight has increased from the late 1970s to the late 1990s, and to evaluate how self-reported weight is associated with weight concern in the different age groups among girls and boys, and how this association has changed over time. MATERIAL A nationally repr...

Statistics catch-up lecture

Example 1. In a genetic study, n = 2217 patients are recruited, among which 1127 have bladder cancer. After whole genome sequencing, p = 475290 single nucleatide polymorphisms (or SNPs, a possible variation of the DNA sequence at one location) are measured on each patient. We construct a matrix X = (Xij)1≤i≤n,1≤j≤p where Xij = 1 if the ith patient has a mutation at jth location and 0 otherwise....
