Lack of Z-DNA Conformation in Mitomycin-Modified Polynucleotides Having Inverted Circular Dichroism [PDF]
, 1983 Poly(dG-dC)· poly(dG-dC) and Micrococcus lysodeikticus DNA were modified by exposure to reductively activated mitomycin C, an antitumor antibiotic. The resulting covalent drug-polynucleotide complexes displayed varying degrees of CD inversions, which are

Topographical variations in the skin barrier and their role in disease pathogenesis
Journal of the European Academy of Dermatology and Venereology, EarlyView.Unlike the gut, the skin appears uniform at first glance. However, histological and molecular biological research has revealed significant regional variations in the composition and function of its main barrier elements. In this review, we describe the topographical differences of four barrier elements in healthy skin: microbiome, chemical, physical ...

Particle aggregation by positive dielectrophoresis [PDF]
arXiv, 2013 Particle aggregates are formed with viable yeast cells (Saccharomyces cerevisiae) and bacterial cells (Escherichia coli and Micrococcus luteus), and are assembled in an interdigitated-castelled microelectrode using positive dielectrophoresis with an alternating current sinusoidal voltage of 2-20 V peak-peak at 1 MHz. The height of S.

Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field [PDF]
, 2019 Plant-microbe associations are thought to be beneficial for plant growth and resistance against biotic or abiotic stresses, but for natural ecosystems, the ecological analysis of microbiome function remains in its infancy.

Fungal dysbiosis following antibacterial monotherapy in canine otitis externa
Journal of Small Animal Practice, Volume 66, Issue 3, Page 149-157, March 2025.Objectives To evaluate evidence of Malassezia overgrowth following successful topical antibacterial monotherapy of refractory canine bacterial otitis using semi‐quantitative cultures. Materials and Methods Twenty‐nine dogs with bacterial otitis were treated topically with either fluoro‐quinolone [0.5% enrofloxacin (18 dogs, 19 treatment events, 25 ears)

Enantiomer-specific isotope analysis of D- and L-alanine: Nitrogen isotopic hetero- and homogeneity in microbial and chemical processes [PDF]
Earth, Life, and Isotopes (Kyoto University Press), pp. 387-402
(2010), 2013 Nitrogen isotopic hetero- and homogeneity of D-{\alpha}-alanine and L-{\alpha}-alanine were investigated in microbial processes in the domain Bacteria and in chemical processes in symmetric organic synthesis. D-alanine is an enantiomer that is physiologically essential for microbial growth and metabolic maintenance.

Influences of plant maternal effects, chemotype, and environment on the leaf bacterial community
Plant Biology, EarlyView.Plant maternal effects and growth environment, rather than terpenoid chemotype, determine the leaf microbial community of Tanacetum vulgare, but specific terpenoids are correlated with the abundance of certain bacteria. Abstract Plant individuals within a species can differ markedly in their leaf chemical composition, forming so‐called chemotypes ...
