Somatic mosaicism of a novel IKBKG mutation in a male patient with incontinentia pigmenti.

Incontinentia pigmenti (IP) is an X-linked, dominant genodermatosis usually fatal in utero in males. In rare circumstances, survival is possible due to abnormal karyotype or somatic mosaicism. In this report, the mechanism and significance of loss of detectable mutation in peripheral blood leukocytes of a somatic mosaic male is discussed and an alternative approach to achieving molecular diagnosis presented.

PLAUR polymorphisms are associated with asthma, PLAUR levels, and lung function decline.

Background: Several studies have suggested that chromosome 19q13.1-3 contains asthma susceptibility genes.

Objective: Linkage and association analyses using 587 United Kingdom and Dutch asthma families (n = 2819 subjects) were used to investigate this region.

Mammalian cell survival and processing in supercritical CO(2).

We demonstrate that mammalian cells can survive for 5 min within high-pressure CO(2)(.) Cell survival was investigated by exposing a range of mammalian cell types to supercritical CO(2) (scCO(2)) (35 degrees C, 74 bar; 1 bar = 100 kPa) for increasing exposure and depressurization times. The myoblastic C2C12 cell line, 3T3 fibroblasts, chondrocytes, and hepatocytes all displayed appreciable but varying metabolic activity with exposure times up to 1 min.
