In the Australian scene, Alex was the Chairman of the first meeting that established the Australian Society for Biophysics as an entity separate from the Australian Institute of Physics in 1975, and served as its President in 1978–1979. Alex produced over 115 major publications, with many in high-profile journals, such as Nature, Science, and the Biophysical Journal. However, he made a special effort to publish in Australian journals, his rational being that if enough good papers were published in them, the journals would attract international attention. Alex was an unassuming man. He read widely, and his thinking was frequently solidly based. He was precise in the use of words, and

I marvelled at the concise way he wrote. He is fondly remembered for his sharp insight, remarkable technical know-how, quick wit and, above all, his infectious passion for science largely driven by a curiosity about electrical events in plant cells. Acknowledgments I am very

“Background The α-proteobacterium Rhodobacter capsulatus is one of several known species of prokaryotes that produces a gene transfer agent [1], or GTA. GTAs are phage-like particles that contain small fragments of the producing cells’ genomes [2] that can then be transferred to other cells in a process similar to generalized transduction. Production of the R. capsulatus GTA, RcGTA, is regulated through multiple E7080 cellular signal transduction systems. These include the GtaRI quorum sensing system [3, 4] and the phosphorelay proteins CtrA and CckA [5, 6] and ChpT [6].

After being annealed on a hot plate at 150°C for 10

After being annealed on a hot plate at 150°C for 10 Adavosertib cost min in order to remove moisture, the samples were spin-coated by a mixed solution of P3HT:PCBM with concentrations of 15 and 12 mg⋅ml-1 in dichlorobenzene at 2,000 r/m for 40 s. Then, the samples were annealed on a hot plate at 150°C for 20 min to remove dichlorobenzene. The whole process was completed in a nitrogen glove box. Finally, Al thin films with a thickness of 150 nm as the cathodes were deposited onto the above layers by magnetron sputtering method through a shadow mask, resulting in active device areas of 7 mm2. The completed photovoltaic structure of ITO/PEDOT:PSS/P3HT:PCBM/Al was annealed

at 150°C for 30 min in the nitrogen glove box. The preparation process of the

CIGS-based polymer solar cells with the structure of ITO/CIGS/P3HT:PCBM/Al (shown in Figure 1a) was similar with that of the conventional polymer solar cell except that the ITO-glass substrates were covered by the layers of the CIGS nanoparticles deposited by PLD replacing the conventional PEDOT:PSS layers. The experimental setup of PLD consists of a Nd:YAG laser with a wavelength of 532 nm, a pulse duration of 5 ns, a deposition chamber with a rotating multi-target, and a base pressure of 1 × 10-6 Torr. The laser GDC-0068 research buy beam was arranged to be incident at 45° on a target this website surface through a quartz window. The laser energy and repetition rate were 50 mJ and 10 Hz, respectively. The CIGS nanoparticles were deposited using a hot-pressed CuIn0.8Ga0.2Se2 target at a substrate temperature of 400°C for 3 min. Figure 1 Layout of a CIGS-based hybrid solar cell and its schematic energy level diagram. (a) Layout of the CIGS-based hybrid solar cell with the structure of ITO/CIGS/P3HT:PCBM/Al. (b) Schematic energy level diagram for the above structure (with energy levels in electron voltage relative to vacuum). The surface and cross-sectional morphology of the CIGS layers and CIGS/P3HT:PCBM bilayer was characterized by scanning electron microscopy (SEM) (XL30FEG, Philips, Amsterdam, Netherlands). The composition

of the CIGS nanoparticles was analyzed by energy dispersive spectroscopy (EDS) fitted on the SEM. The crystallinity of the CIGS layers was examined by X-ray diffraction (XRD) (D/MAX-IIA, Rigaku, Tokyo, Japan) using the Cu Kα radiation. The UV-vis absorption spectroscopy Staurosporine manufacturer of the P3HT:PCBM blend monolayer and CIGS/P3HT:PCBM bilayer was detected by an ultraviolet-visible spectrophotometer (U-3000, Hitachi, Tokyo, Japan). The current density-voltage (J-V) characteristics of the unencapsulated samples were tested in air by using a Keithley 2400 SourceMeter (Cleveland, Ohio, USA) under air mass (AM) 1.5 global solar condition at 100 mW/cm2. The photoluminescence (PL) of the P3HT:PCBM blend monolayer and CIGS/P3HT:PCBM bilayer was measured at room temperature using a 325-nm He-Cd laser as the exciting light source.

The sequence encoding the first 165 amino acids of RecU was subse

The sequence encoding the first 165 amino acids of RecU was subsequently deleted from the native chromosomal locus using plasmid pMADrecUKO as described above. To clone recU into the spa locus, the entire recU coding sequence and the RBS was amplified by PCR using primers recUp8 and recUp9. The PCR product was digested with XmaI and XhoI restriction enzymes and cloned into pBCB13 generating the plasmid

Givinostat in vivo pBCB13recUspaL. The insert was sequenced, the plasmid was introduced into RN4220 by electroporation and subsequently transduced into NCTC8325-4. Integration and excision of the plasmid in the chromosome was performed as previously described [24] and the resulting strain, which contains two copies of recU in the chromosome, one in the native locus and another in the spa locus, was named 8325-4recUspaL. In order to delete recU from its normal locus in the background of strain 8325-4recUspaL, the pMADrecUKO plasmid was transduced into this strain and deletion of the recU gene was performed

and verified as described in the previous paragraph, but in the presence of IPTG, resulting in the strain BCBRP001. In order to ensure tight regulation of the expression of recU from the P spac promoter [30] we transduced the pMGPII plasmid, which encodes the see more lacI gene [26], into BCBRP001 and the resulting strain was named 8325-4recUi. SpoIIIE-YFP localization To study SpoIIIE localization in BCBHV008 [23] and 8325-4recUi strains, derivatives of these strains expressing a C-terminal SpoIIIE-YFP fusion from its native locus were constructed. For that Blasticidin S purpose, a DNA fragment encompassing a copy of the spoIIIE gene without

its STOP codon and encoding a five amino acid linker was cloned, in frame with the yfp gene, in the pMUTINYFPKan plasmid [27]. This fragment was amplified from NCTC8325-4 genomic DNA using primers spoIIIEp1 and spoIIIEp2, digested with KpnI and cloned Methocarbamol into pMUTINYFPKan, giving rise to pBCBHV007. The insert in pBCBHV007 was sequenced and this plasmid was used as a template to amplify a DNA fragment containing the 3’ end of the spoIIIE gene (1065 bp) connected to the linker and the yfp gene, using primers spoIIIEp3 and spoIIIEp4. This fragment was digested and cloned into the BamHI and XmaI restriction sites of the pMAD vector [24], generating plasmid pMADspoIIIEyfp. A second PCR product, encompassing the last 64 bp of spoIIIE (containing the Shine-Dalgarno sequence of the downstream gene) and the 1 Kb region downstream of spoIIIE, was amplified from NCTC8325-4 genomic DNA using primers spoIIIEp5 and spoIIIEp6. The PCR product was digested with XmaI and NcoI and subsequently cloned into pMADspoIIIEyfp generating the plasmid pBCBHV008.

Out of 64 pairs isolated we retrieved 19 sets of clones in which

Out of 64 pairs isolated we retrieved 19 sets of clones in which both

sides of the separated cells continued to grow. They were then cultured in 1× SPP containing 1 μg/mL CdCl2. Because the expression of HA-Cre1p severely inhibits the growth of Tetrahymena, one side of the clones in each set was expected to grow slowly in the presence of CdCl2. Indeed, in 13 out of the 19 sets of the clones studied, severe growth suppression was detected in one side of Barasertib purchase the clones. In the other 6 sets, both sides of cells grew at equal speed. These are likely to represent progeny cells and were not analyzed further. Figure 4 N-terminal EGFP-tagging of ITF2357 TWI1 using Cre/loxP system. (A) A scheme of induction of Cre-mediated loxP recombination and selection of loxP-EGFP-TWI1 cells. See text for details. (B) loxP excision analysis by PCR. Total genomic DNA was extracted from 13 presumptive loxP-EGFP-TWI1 strains and analyzed by PCR using the primers shown in Fig. 3A. The products corresponding to the non-excised loxP-neo4-loxP-EGFP-TWI1 locus (+neo4) and the excised loxP-EGFP-TWI1 locus (-neo4) are marked by arrows. We expected that the clones growing poorly in the presence of CdCl2 were derived from the CRE556 strain, while the normally growing clones originated from the loxP-neo4-loxP-EGFP-TWI1

strain. Genomic DNA was extracted from the latter clones and excision of the neo4 cassette was observed by PCR. As shown in Fig. 4B, the PCR product corresponding PIK3C2G to the neo4-excised loxP-EGFP-TWI1 locus was observed in 10 out of 13 clones studied. This result indicated that they indeed were derived from the loxP-neo4-loxP-EGFP-TWI1 find protocol strain and Cre-recombinase expressed in the CRE556 side of the pair was transported to the loxP-neo4-loxP-EGFP-TWI1 side and efficiently

induced neo4 excision. Only one clone failed to produce any PCR products. This clone could be either derived from the CRE556 strain or from progeny cells that we could not correctly identify by the growth assay in the presence of CdCl2. Therefore, the method we established here can efficiently identify parental cells derived from a loxP-possessing strain. To assess the correct excision of the neo4 cassette in these clones, they were crossed with the wild-type strain CU428 and EGFP-Twi1p expression was observed. In all 3 clones (#1, #11 and #13 in Fig. 4B) analyzed, EGFP-Twi1p was exclusively expressed during conjugation and was localized to the macronucleus. EGFP-Twi1p localization of clone #1 is shown in Fig. 5. The expression of EGFP indicated that neo4 was most likely excised precisely at the two loxP sites because imprecise excision might cause a frame-shift that abolishes EGFP-Twi1p expression.

Discussion Pulsed Electric Fields in Tumor Electrical Treatment R

Discussion Pulsed Electric Fields in Tumor Electrical Treatment Recent advance in biomedical engineering has Selinexor clinical trial enabled great progress in pulsed electric fields. Microsecond electric pulse with weak intensity can create reversible membrane electroporation to enhance drug-uptake such as chemotherapeutic drugs, antibody and exogenous macromolecule substance which are impermeable under normal conditions. Reversible electroporation can be used in electrochemotherapy

to sensitize cancer cells to anticancer drugs or learn more in transcutaneous drug delivery [3]. An European project (European Standard Operating Procedures of Electrochemotherapy, ESOPE) had proven electrochemotherapy to be an easy, highly effective, safe and cost-effective

approach for the treatment of cutaneous and subcutaneous tumors of different malignancies [21, 22]. Furthermore, Microsecond electric pulses with intensive energy often induce irreversible membrane Entospletinib datasheet electroporation which can be used to implement tumor ablation directly without any drugs [5]. On the other hand, when shorten the duration of the pulse from microsecond to nanosecond, nanosecond electric pulse can penetrate the intact plasma membrane to impose electric force on multiple subcellular structures and induce multiple biophysical effects known as intracellular electromanipulation, which can be used in cancer treatment, gene therapy and wound healing [7]. The application of microsecond or nanosecond electric pulse in caner treatment has been the focus and was widely accepted by researchers. However, to our knowledge, few researchers have investigated the biophysical effects regarding the combined application of microsecond and nanosecond duration electric pulse in cancer treatment. Rho Recently, according to an “”online release”" appeared on the official website of the Frank Reidy Research Center for Bioelectrics in Old Dominion University, a dual pulsing system combining long pulses, which open pores in the outer cell membrane, and short

pulses, that affect intracellular structures and molecular transport, to enhance gene delivery to the nucleus, was under development [23]. For the first time, we reported the use of both types of electric pulse in this study. We were convinced that the application of this new technology would be of great value in clinical medicine. SPEF was a kind of electric energy transmission method which was unique from existing micro- or nano-second electric pulse. It was designed to combine micro- and nano-second electric pulse into one integral exponential decayed pulses simultaneously. SPEF had a fast rise-time at nanosecond level, containing a large spectrum of high electromagnetic frequencies, and a long queue at microsecond level with low electromagnetic frequencies.

Growth of L sakei strains

Growth of L. sakei strains learn more on glucose and click here ribose The ten strains investigated showed faster growth rates when utilizing glucose as the sole carbon source (DMLG; glucose 0.5%) compared with ribose (DMLR; ribose 0.5%), a finding in agreement with previous observations [16–18, 30], confirming that glucose is the preferred carbon source in L. sakei. Preliminary 2-DE analysis of strains 23K, MF1053 and LS 25 resulted in gels with large differences in protein spot resolution (results not shown). Gels of samples issued from bacteria grown on ribose as the sole carbon source were of poor quality. Cell proteolysis due to slow growth and prolonged incubation

time may result in protein degradation and solubilization defect, as has previously been proposed [44]. Previous studies suggested a regulation of ribose utilization by the PTS and co-metabolism of these two sugars that are present in meat [17, 19, 21]. Since the addition of small amounts of glucose has been described to enhance growth on ribose [45], we used DMLRg (ribose 0.5%, glucose 0.02%) for further experiments. This indeed resulted in faster growth rates DMXAA purchase and a better spot

resolution of the resulting 2-DE gels that were comparable to the gels from bacterial samples grown in DMLG (results not shown). Thus further experiments were performed by growing bacteria in DMLG and DMLRg to study the glucose and ribose metabolisms, respectively. Protein patterns of the ten L. sakei strains After growth on glucose (in DMLG) and ribose (in DMLRg) an average of approximately 400 spots was observed after 2-DE in the pI range investigated. A variation of about 20% in the number of spots was detected

between the strains, as previously observed within the species [29, 35]. The overall protein expression pattern was similar for the different why strains grown on both carbon sources (data not shown), though distinct differences in the 40-kDa region of the 2-DE gels were observed (Figure 1). These differences were identified as resulting from two different migration profiles of four isoforms (different pI) of the glyceraldehyde-3-phosphate dehydrogenase (GapA) protein. The isoforms displayed a size variation, previously described by Chaillou et al. [29] to differentiate two L. sakei subgroups. Grouping of our ten strains based on the GapA isoforms migration profile was identical to the two genetic clusters previously obtained from rapidly amplified polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP), and microarray-based comparative genome hybridization (CGH) analyses [30]. If those grouping methods reflect the subspecies division of L. sakei, eight of our strains including the sequenced strain 23K and the type strain CCUG 31331 belong to L. sakei subsp. carnosus, while the type strain DSM 20017 and the commercial starter culture strain LS 25 belong to L. sakei subsp. sakei.

Results Phenotypic features and clonal relatedness of CF

Results Phenotypic features and clonal relatedness of CF strains A total of 9 out of 25 P. aeruginosa strains tested showed mucoid phenotype on MHA, while 3 exhibited SCV phenotype. Among 15 S. aureus Eltanexor check details isolates tested, 7 were methicillin-resistant. PFGE analysis showed 8, 21, and 12 different pulsotypes among S. aureus, S. maltophilia, and P. aeruginosa isolates, respectively. Among S. aureus isolates, only the PFGE type 1 was shared by multiple

strains, which comprised 8 isolates and 7 PFGE subtypes. Among S. maltophilia isolates, 2 multiple-strains PFGE types were observed: PFGE type 23 (5 isolates, 2 PFGE subtypes), and PFGE type 73 (2 isolates with identical PFGE profile). Among P. aeruginosa isolates, 5 multiple-strains PFGE types were observed: PFGE type 5 (6 isolates, 2 PFGE subtypes), PFGE type 1 (4 isolates with indistinguishable PFGE profile), PFGE types 9 and 11 (3 isolates each, with identical PFGE pattern), and PFGE type 8 (2 isolates, one PFGE subtype) (data not shown). In vitro activity of AMPs and Tobramycin against planktonic cells: MIC, MBC In order to determine the efficacy of AMPs, the antimicrobial activity was measured against 67 CF clinical isolates, and results CDK inhibitor are summarized in Table 1. Overall, BMAP-28 showed the widest activity spectrum among AMPs tested, as suggested

by MIC90 and MBC90 values (16 μg/ml, for both), although all of them exhibited a species-specific Axenfeld syndrome activity. In fact, although AMPs showed comparable activity against P. aeruginosa, BMAP-28 was found to be more active than P19(9/B) against S. maltophilia, and resulted the best active AMP against S. aureus (MIC90: 32 μg/ml; MBC90: 32 μg/ml). Compared

to AMPs, Tobramycin exhibited a lower activity (MIC90 and MBC90: >64 μg/ml) regardless of the species considered. Killing quotient values, calculated as MBC/MIC ratio, were < 4 for all AMPs, as well as for Tobramycin, clearly suggesting a bactericidal activity. No differences in susceptibility levels to AMPs were found with regard to phenotype (mucoid, SCV, MRSA), pulsotype, or susceptibility to Tobramycin (data not shown).

The scuttle fly species, with a known biology, accounted for 43 2

The scuttle fly species, with a known biology, accounted for 43.2 % (S = 79) of the compared species. The losers of the transformation after disturbances, were the species with mycophagous (S = 21)

and zoophagous (S = 19) larvae. Among the species of fungus-feeding/fungus-breeding larvae (twenty species of the genus Megaselia and Triphleba minuta) inhabiting Pine Forests (BF, TF, BPF and PF), only six were found in clear-cuts and four in left- and logged-windthrow plots. In clear-cut plots I have found five zoophagous species (Megaselia ciliata, M. major, M. mallochi, Phalacrotophora fasciata and Triphleba lugubris). Also, in the left-windthrow plots in PF I have found five species with zoophagous larvae (M. ciliata, M. elongata, M. flavicoxa, Phora holosericea selleck kinase inhibitor and Pseudacteon fennicus), and in the logged-windthrow plots, the same zoophagous species, except M. flavicoxa. In the old-growth stands, I have found nearly three times more (S = 17) species with zoophagous

larvae, compared to disturbed habitats. Among the species with polyphagous larvae (S = 3), M. giraudii-complex reached very high abundance in the MK-8931 chemical structure old-growths plots of all compared forest complexes (BF, TF Epigenetics inhibitor and BPF) (Table 1). Similarity of the scuttle fly communities Within-locality similarity of the scuttle fly communities was much higher for the Pisz Forest (Sørensen index between left- and logged-windthrow plots amounts to 0.76) Resminostat than for the three remaining forest complexes (0.41, 0.39 and 0.39 for old-growths vs. clear-cuts in BF, TF, and BPF, respectively). In general, the communities recorded in the same habitat type-clear-cuts or old-growths stands—in different forest complexes (up to 300 km apart) were found to display greater similarity than those recorded on adjacent plots

in a given forest complex (c.a. 1 km apart), but covering different habitats. As a result, data from old-growth and clear-cut plots constituted separated clusters. The scuttle fly communities recorded in Pisz Forest (both left- and logged-windthrow plots) show greater similarity to those from clear-cut stands than that from old-growth stands (indices of similarity: Sørensen, Baroni-Urbani and Morisita-Horn) (Table 1; Fig. 2). Fig. 2 a, b, c Claster analyses, using the indices of similarity (presence/absence species), showed that young pine plantations (BPF clear-cuts, BF clear-cuts and TF clear-cuts) and post-windstorm habitats (PF left-windthrow and PF logged-windthrow) shared similar scuttle fly communities, while intact forest stands (BPF old-growths, BF old-growths and TF old-growths) composed a second group (unpublished material) Diversity of the scuttle fly communities The scuttle fly communities found in clear-cut plots appeared to be distinctly less diverse in terms of the number of species for a given number of sampled individuals, relative to old-growth habitats (data for the three localities pooled).
