Their structures were determined by using H-1 NMR spectroscopy, and their sizes were evaluated by using a series of pulsed-field gradient NMR experiments. The effect of anion has been studied, and the cation selectivities have been investigated by a series of competition experiments.},

	abstract = {Thiolate ligand oxygenation is believed to activate cytotoxic half-sandwich [(eta(6)-arene)Ru(en)(SR)](+) complexes toward DNA binding. We have made detailed comparisons of the nature of the Ru-S bond in the parent thiolato complexes and mono- (sulfenato) and bis- (sulfinato) oxygenated species including the influence of substituents on the sulfur and arene. Sulfur K-edge XAS indicates that S(3p) donation into the Ru(4d) manifold depends strongly on the oxidation state of the sulfur atom, whereas Ru K-edge data suggest little change at the metal center. DFT results are in agreement with the experimental data and allow a more detailed analysis of the electronic contributions to the Ru-S bond. Overall, the total ligand charge donation to the metal center remains essentially unchanged upon ligand oxygenation, but the origin of the donation differs markedly. In sulfenato complexes, the terminal oxo group makes a large contribution to charge donation and even small electronic changes in the thiolato complexes are amplified upon ligand oxygenation, an observation which carries direct implications for the biological activity of this family of complexes. Details of Ru-S bonding in the mono-oxygenated complexes suggest that these should be most susceptible to ligand exchange, yet only if protonation of the terminal oxo group can occur. The potential consequences of these results for biological activation are discussed.},

Multivalent cationic sites are added to these polymers by a post-amination and quarternization reactions. Blood compatibility studies using these polymers at different concentrations showed insignificant effects on complement activation, platelet activation, coagulation, erythrocyte aggregation and hemolysis compared to branched cationic polyethyleneimine (PEI). The degree of quarternization does not have large influence on the blood compatibility of the new polymers. Cytotoxicity of these polymers is significantly lower than that of PEI and is a function of quarternized nitrogen present in the polymer. Also, these polymers bind DNA in the nanomolar range and are able to condense DNA to highly compact, stable, water soluble nanoparticles in the range of 60-80 nm. Gel electrophoresis studies showed that they form electroneutral complexes with DNA around N/P ratio 1 irrespective of the percentage of quarternization under the conditions studied.

	abstract = {The arsC gene is responsible for the first step in arsenate biotransformation encoding the enzyme arsenate reductase. The quantitative real-time PCR method was developed to quantify the abundance of the arsC genes in environmental samples contaminated with arsenic. Two sets of primers that showed high specificity for the target arsC gene were designed based on consensus sequences from 13 bacterial species. The arsC gene was used as an external standard instead of total DNA in the calibration curve for real-time PCR, which was linear over six orders of magnitude and the detection limit was estimated to be about three copies of the gene. Soil samples from arsenic contaminated sites were screened for arsC genes by using PCR and showed the presence of this gene. The copy numbers of the gene ranging from 0.88 x 10(4) to 1.56 x 10(5) per ng total DNA were found in eight arsenic contaminated samples. Soil samples from a bioreactor containing pulp mill biomass and high concentration of arsenate showed a tenfold higher count of arsC gene copies than soil samples collected underground from an arsenic-rich gold mine.

The deduced amino acid sequences of the intracellular and secreted versions of equine gelsolin infer polypeptides of 731 and 755 residues with apparent molecular masses of 80.7 kDa and 83.2 kDa, respectively. Multiple sequence alignment analysis of equine, human, porcine, and murine orthologs of gelsolin demonstrates prominent similarities among all of these proteins, with the horse and human molecules exhibiting the largest degree of likeness with respect to polypeptide length and overall sequence composition. Both horse and human plasma gelsolins are comprised of 755 amino acids with 94\% of the residues identical, while the degree of sequence identity in the shorter (731 residues) cytoplasmic gelsolins is 95 \%. Analysis of the sequences and structures of the six related domains that comprise gelsolin emphasizes the strong correlation that exists between primary structural conservation among mammalian gelsolins and maintenance of the three-dimensional domain fold characteristic of members of this protein family.},

Binding is driven by an increase in entropy, with little or no enthalpic contribution.

The hemagglutinin is different from two other mannose-resistant hemagglutinins in this strain, K99 and F41. The agglutinin, named heat-resistant agglutinin 1 (HRA1) since heating to 70 degrees C does not destroy its aggregative properties, strongly agglutinates human, pig, and dog erythrocytes, shows little or no affinity towards cow and chicken erythrocytes, but agglutinates human colon adenocarcinoma 201 (COLO 201) cells. The hra1 gene present on the recombinant plasmid pETE1 was localized by subcloning, and its nucleotide sequence was determined. The gene consists of a 792-bp open reading frame coding for a putative protein of 29 kDa with a predicted N-terminal secretory signal sequence. HRA1 shares no significant identity with data base protein sequences. HRA1 is strongly associated with the bacterial membrane, resisting sonication and isolation attempts based upon standard adhesin purification techniques. N-terminal sequencing of a unique 25-kDa band present in polyacrylamide gels of outer membrane preparations of bacteria harboring pETE1 correlated with the predicted N-terminal amino acid sequence of HRA1 after cleavage of the signal peptide. A viscometric agglutination assay sensitive to the strength of bacterial adhesion shows that the agglutination mediated by bacteria expressing HRA1 is weaker than that of bacteria bearing the F41 adhesin, probably because of the high-molecular-weight, multivalent nature of the latter adhesin. Our observations suggest that HRA1 is a monomeric outer membrane agglutinin.},

Twelve anionic sulfonated and seven cationic methylpyridinium porphyrins, usually containing other functional groups (phenyl, pyridyl, nitro- and amino-phenyl), are reported on. Twelve of these porphyrins are new, and all nineteen porphyrins are characterized by H-1 NMR. UV-VIS data are presented for the isolated porphyrins, while mass spectral data are noted for selected compounds. Partition coefficients of the porphyrins in octanol-water, and the accumulation of the porphyrins in HT-29 cells of a human-cancer tumor, were measured and both were inversely related to the charges of the porphyrins. The 11 porphyrins soluble in biological buffer solutions are basically nontoxic to Chinese hamster ovary (CHO) cells in oxic or hypoxic conditions or to aerobic HT-29 cells at the 100 mu M concentration used (which is sometimes limited by solubility). No significant X-ray radiosensitization was observed for selected porphyrins toward CHO cells at the 100 mu M concentrations used, but some photosensitized cell kill (using 630 nm light) was observed using the disodium salt of 5,10-bis(4-pyridyl)-15,20-bis(4-sulfonatophenyl)porphyrin (24).},
