Global budgets of atmospheric trace gases are increasingly being constrained by means of stable isotope measurements. Published analytical techniques for studying the parallel stable isotopic composition of methane (d 13 C and d D) require prohibitively large quantities of methane for analysis, maki
The photosensitizingicytotoxic effects of four porphyrin compounds derived from hematoporphyrin were compared using two human tumor cell lines with a soft-agar colony-forming assay. Reproducible dose-and timedependent increases in reproductive cell death were observed for each porphyrin tested. Two
Owing to the presence of outliers, an estimated 3.5% in the ridge breadth data and 1.7% in the height data, the effect of fragile X on height and ridge breadth was examined using robust statistical techniques for data collected from 54 families afflicted with this disorder. It is shown that fragile
