Pulse-field actuation of collinear magnetic single crystals
… the application of a relatively small magnetic field. The large strains exhibited by such materials are a result of the coexistence of several features, including a thermoelastic martensitic transition, and a ferromagnetic martensite (non-equilibrium, low-temperature) phase. The …

Tunable High-Field/ High-Frequency ESR and High-Field Magnetization on Single-Molecule Clusters
… been studied by application of high magnetic fields. The magnetization has been probed with an MPMS as function of temperature and field. The combination with pulse field measurements up to 52\,T allowed determination of the magnetic exchange coupling parameters, and to probing the effective …

Microbial degradation of high molecular weight polycyclic aromatic hydrocarbons
… of the three strains was possible by pulse field gel electrophoresis and DNA:DNA hybridisation methods. The St. maltophilia strains had similar degradative profiles to community five.

ATM-Dependent ERK Signaling in Response to DNA Double Strand Breaks
… equivalent to 0.2 - 20 Gy of IR, as detected by pulse-field gel electrophoresis, accompanied by dose-dependent H2AX phosphorylation at ser-139 and ATM phosphorylation at ser-1981, indicating ATM activation. Furthermore, BrdU photolysis increased phosphorylation of Chk2 (at thr-68) and p53 (at …

The frequency and characterization of streptococci in aerobic vaginitis (AV) and its association with pregnancy outcomes
… predominant serotype, followed by serotype III. Pulse field gel electrophoresis (PFGE) profile analysis for both GBS and E. faecalis yielded a total of 24 restrictions profiles for GBS and 16 for E. faecalis. Multivariable analysis revealed that parity, gravidity, vaginal discharge, urinary tract …

The Microbiome of Cystic Fibrosis Sputum and its Association with Incident Lower Airway Infections
… bacterial bioburden. Strains were typed using pulse-field gel electrophoresis to differentiate strain types and distinguish incident infection episodes. Results from this work showed that the microbial community of pwCF that eventually developed P. aeruginosa, or S. maltophilia incident …

Identification of a chromosomal region possibly involved in O-side chain biosynthesis in Brucella abortus
… parameters such as cell growth stage, pulse field strength and pulse length were optimized. It was determined that using late log phase cells (approximately 70-77 Klett units), 10 ms and 13 KV/cm were the best conditions for achieving transformation by pNW-2 or pNW3. Kanamycin resistant …

Terahertz driven intraband dynamics of excitons in nanorods
… of excitons generated via a short optical pulse. We calculate the energies and wavefunctions for the excitons within the envelope function approximation in the low density limit where there is at most one exciton per nanorod. The linear Terahertz transmittance and absorbance is found for …

The development of tools to allow genetic and genomic analysis of Frankia
… sizes of the three strains were determined by pulse-field gel electrophoresis (PFGE) and estimated to be 5.5Mb for Ccl3, 9.1 Mb for EAN1pec and 8.5Mb for Eul1c. Several members of the actinomycetales have linear chromosomes; however, our experiments on topology show that the Frankia chromosome …

The role of recombinational repair in the mechanism of killing during thymine starvation in Escherichia coli
… during TLD using physical methods, such as pulse-field gel electrophoresis to measure levels of double strand breaks. I next investigated the role of major DNA repair and recombinational repair pathways by studying the effect of their inactivation on survival during thymine starvation. …

Molecular Approaches to the Genetics of Obesity: Mapping and Characterization of the Murine Diabetes (db) Gene
… these flanking markers and genetic resources, pulse-field electrophoresis mapping, and YAC cloning of the region has begun. These studies should facilitate the eventual cloning and characterization of the db gene.</p>

Movement and Stability of the Staphylococcal Cassette Chromosome mec among Staphylococcus aureus
… SCCmec type I to recipient strains of S. aureus. Pulse-field gel electrophoresis and mec-associated dru typing were used to confirm the identity of the transductants. Transfer of mecA via transduction occurred at low frequency and required extended selection times for mecA gene expression as well …

Indagine sulla presenza di Helicobacter pullorum in allevamenti avicoli italiani
… different farms were submitted to genotyping by Pulse-Field Gel Electrophoresis (PFGE). In order to assess the molecular basis of fluorquinolone resistance in H. pullorum, gyrA of H. pullorum CIP 104787T was sequenced and nucleotide sequences of the Quinolone Resistance Determining Region (QRDR) …
