During the period between 1999 and 2006, wood-feeding cockroaches in the Cryptocercus punctulatus Scudder species complex were collected throughout Great Smoky Mountains National Park, USA. The chromosome numbers of insects from 59 sites were determined, and phylogenetic analyses were performed based on mitochondrial COII and nuclear ITS2 DNA. The distribution of the three male karyotypes found...

Single-strand conformation polymorphisms at 16S2 and COII mitochondrial genes were surveyed in 111 housefly samples from North, Central, and South America, Europe, Asia, Africa, and the Western Pacific. Forty-eight phenotypes were detected, of which none were ubiquitous, and 21 (44%) were confined to a single zoogeographical region. Nei's gene diversity index (H(S)) was 0.27 and was heterogeneo...

At the ends of bacteriophage P2 DNA, the S’-terminated strands are 19 nucleotides longer than the 3’-terminated strands. The complete nucleotide sequence of the two cohesive ends of P2 DNA has been determined. This was accomplished by repair synthesis, using Escherichia coIi DNA polymerase and labeled deoxyribonucleoside triphosphates with or without a ribonucleoside triphosphate, followed by p...

A leucyl, phenylalanyl transfer RNA-protein transferase has been purified nearly 300-fold from the 105,000 X g supernatant fraction of Escherichia coIi. The procedure consists of extraction of the precipitate formed with protamine sulfate, gel filtration on Sephadex G-100 and Sephadex G-75, and chromatography on diethylaminoethyl cellulose. The enzyme preparation specifically catalyzes the tran...

VT transition from the high-spin CoII to low-spin CoIII state was observed for complex (N-cyclo-hexyl-2-iminopyridine)(3,6-di-tert-butyl-o-benzosemiquinonato)(3,6-di-tert-butyl-catecholato)cobalt in both solid and liquid form. For first time we demonstrate a low-temperature nanosecond pump-probe XANES experiment revealing valence tautomeric solution of Co complex. Reversible induced under tempe...

We synthesized and characterized (IR, Raman, UV, SXRD) hexaamminecobalt(III) dichloride permanganate, [Co(NH3)6]Cl2(MnO4) (compound 1) as the precursor of Co–Mn–spinel composites with atomic ratios Co:Mn = 1:1 1:3. The 3D?hydrogen bond network includes N–HO–Mn N–HCl interactions responsible for solid-phase redox reactions between permanganate anions ammonia ligands. temperature-limited thermal ...
