Refined localization of twenty-one genes in subregion p13.1 of human chromosome 1.

In this report, we describe a refinement of the human transcript map of chromosome 1p13.1, a subregion undergoing many aberrations in various types of human cancers. Publicly available genetic linkage, radiation hybrid and physical maps, as well as cytogenetic and sequence data were used to establish the relative order and orientation of ten known intragenic markers. The complete sequence of genomic clones of the region, available at the Sanger Centre, provided the tool for further studies performed by BLAST analysis against all cDNA sequences registered in the Genexpress Index2. This allowed us to assign to subband 1p13.1 nine of the ten known genes, an additional member of the gene family of one of these genes and eleven new transcripts. The remaining known gene and one additional new transcript map at the 1p13.1 and 1p13.2 boundary. The corresponding genes may be responsible for disorders related to this region. The resulting transcript map of 1p13.1 is presented in the printed article with additional data available on a dedicated Web site at the address http://idefix.upr420.vjf.cnrs.fr/CARTO.

[Present problems in x-ray diagnostics--introductory review (author's transl)].

Introductory article for a series on problems about appropriate applications in x-ray diagnostics; the following questions are dealt with:--Did the development of clinical x-ray diagnostics keep up with the technological development?--Are the costs arising in x-ray diagnostics still tolerable compared with the benefits?--Is it possible to reduce the somatic and genetic population exposure by means of appropriate measures or is it only possible to "simply" accept it?

The longest illness. Effects of nuclear war in children.

The destruction of civilization that would follow a nuclear war would render any disaster ever recorded insignificant. Millions of people would perish during the first few hours, and many more would die in the months to come. Survival would exist only in the strictest sense of the word, since societal disorganization, famine, drought, darkness, and nuclear winter would envelope the earth. The comparative frailty of children and their dependence on adults would render them most susceptible to the acute effects of a nuclear holocaust. Furthermore, studies of the Hiroshima and Nagasaki, Japan bombings showed a disproportionate propensity for children to experience leukemias and other cancers years after the bombings. There were also great increases in perinatal deaths and cases of microcephaly and retardation in children exposed in utero to the bombs. In the event that there are future generations after a nuclear war, the issue of heritable genetic effects will become important. Suggestions of permanent genetic damage are emerging from the Hiroshima and Nagasaki studies. By comparison, the genetic effects of modern weaponry will be incalculable.
