The content and the isotopic composition of lead (Pb) were studied in a peat deposit on the ridge of the Brdy Hills, in the vicinity of the Príbram metallurgical works, in the Czech Republic. Quadrupole ICP MS was employed to determine the elemental composition and (206)Pb/(207)Pb and (208)Pb/(206)Pb isotope ratios. The individual layers were dated using alpha spectrometric measurement of the (...

A mutant, USDA 206C, of Rhizobium fredii USDA 206 was obtained by passage on acridine plates. This mutant was cured of its 197-megadalton Sym plasmid but retained its symbiotic effectiveness. Multiple plasmid and chromosomally borne nif gene copies have previously been shown in R. fredii USDA 206. HindIII and EcoRI restriction enzyme digests of plasmid and total DNA showed that at least two nif...

Lung cancer is a deadly disease that ends numerous lives around the world. MicroRNAs (miRNAs) are a group of non-coding RNAs involved in a variety of biological processes, such as cell growth, organ development, and tumorigenesis. The miR-206/133b cluster is located on the human chromosome 6p12.2, which is essential for growth and rebuilding of skeletal muscle. The miR-206/133b cluster has been...

The complexities of cellular regulations seem to never end. RNA, in particular, appears to exert ever-new regulatory functions in an astonishing variety of ways. miRNAs are especially wondrous, in that they can modulate hundreds of targets at once. Dissecting the cellular effects of myriad such multiplex regulations will probably keep biologists busy for many years to come. in this issue of Cel...

Ninety-one strains of Pseudomonas pseudomallei were tested in the API 20E system and in equivalent conventional tests. Except for utilisation of citrate there was good correlation between API and conventional tests. Seven-digit profiles were constructed from each strain after 48 hours' incubation, and numerical codes 2 006 727, 2 206 706, 2 206 707, and 2 206 727 accounted for 77% of strains te...
