The biosynthetic genes for clavulanic acid and cephamycin production occur as a âsuper-clusterâ in three<i>Streptomyces</i> (1993)

The cosmid cloning vector pHC79 has been used to clone fragments of chromosomal DNA from the Streptomyces: S. clavuligerus, S. jumonjinensis and S. katsurahamanus. These strains all produce both the beta-lactam antibiotic, cephamycin and the beta-lactamase inhibitor, clavulanic acid. Although structurally related these two beta-lactams are known to be derived from different biosynthetic precursors. Hybridisation studies and restriction mapping have shown that the gene clusters encoding the two biosynthetic pathways are chromosomally adjacent in these strains, thus creating a 'super-cluster' of genes involved in both the production and enhancement of activity of a beta-lactam antibiotic.
Online sequential ELM based transfer learning for transportation mode recognition (2013)

Transportation mode recognition plays an important role in discovering life patterns from people's physical behavior. Learning knowledge from mobile sensing data enables transportation mode recognition on mobile phone. However, existing transportation mode recognition methods are mostly based on fixed recognition models, which do not consider the diversities in different users and their transportation context. In this paper, an online sequential extreme learning machine based transfer learning method (TransELM) is proposed to recognize various transportation modes. TransELM is mainly comprised of three steps: firstly, an initial ELM classifier is trained on the labeled training data from the source domain; secondly, the mean and standard deviation are calculated as multi-class trustable intervals in source domain, and then the partially trustable samples are effectively extracted from the target domain; thirdly, the trustable samples are integrated, where an incremental OSELM method is employed to update the original ELM classifier. Experimental results show that TransELM obtains higher accuracy than the traditional ELM classifier in real world transportation mode recognition problems.
New <i>rfp</i> - and pES213-Derived Tools for Analyzing Symbiotic <i>Vibrio fischeri</i> Reveal Patterns of Infection and <i>lux</i> Expression In Situ (2006)

Genetically altered or tagged Vibrio fischeri strains can be observed in association with their mutualistic host Euprymna scolopes, providing powerful experimental approaches for studying this symbiosis. Two limitations to such in situ analyses are the lack of suitably stable plasmids and the need for a fluorescent tag that can be used in tandem with green fluorescent protein (GFP). Vectors previously used in V. fischeri contain the p15A replication origin; however, we found that this replicon is not stable during growth in the host and is retained by fewer than 20% of symbionts within a day after infection. In contrast, derivatives of V. fischeri plasmid pES213 were retained by approximately 99% of symbionts even 3 days after infection. We therefore constructed pES213-derived shuttle vectors with a variety of selectable and visual markers. To include a visual tag that can be used in conjunction with GFP, we compared seven variants of the DsRed2 red fluorescent protein (RFP): mRFP1, tdimer2(12), DsRed.T3, DsRed.T4, DsRed.M1, DsRed.T3_S4T, and DsRed.T3(DNT). The last variant was brightest, displaying >20-fold more fluorescence than DsRed2 in V. fischeri. RFP expression did not detectably affect the fitness of V. fischeri, and cells were readily visualized in combination with GFP-expressing cells in mixed infections. Interestingly, even when inocula were dense enough that most E. scolopes hatchlings were infected by two strains, there was little mixing of the strains in the light organ crypts. We also used constitutive RFP in combination with the luxICDABEG promoter driving expression of GFP to visualize the spatial and temporal induction of this bioluminescence operon during symbiotic infection. Our results demonstrate the utility of pES213-based vectors and RFP for in situ experimental approaches in studies of the V. fischeri-E. scolopes symbiosis.
Electroluminescence from isolated CdSe∕ZnS quantum dots in multilayered light-emitting diodes (2004)

Electro- and photoluminescence spectra of the CdSe∕ZnS core-shell quantum dots (QDs) covered by various organic ligands and incorporated into multilayered light-emitting diodes (LEDs) were recorded by a confocal optical microscope. The QDs were dispersed in a hole transporting material, N,N’-Diphenyl-N,N’-bis(3-methylphenyl)-1,1’-biphenyl-4,4’-diamine (TPD), to investigate the LED performance at different QD concentrations and the effect of different surface modifications on the isolated QDs. No wavelength shift was observed in the electroluminescence spectra from the QD LEDs with or without the TPD. The peak energies of the electro- and photoluminescence showed only small spectral shifts (several nanometer) for the diluted QDs and no dependence on the QD-concentration, surface ligands, or conductive polymers that were used. This suggests that the relative peak shifts are related to the different filling processes in the CdSe QDs under photo excitation and electric injection, rather than to the “chemical” effects on the surface of the CdSe∕ZnS QDs.
A Web-based Environment for Medical Collaboration in a Regional Healthcare Network * (1997)

The Center for Medical Informatics and Health Telematics Applications (CTI-HTA) at the Institute of Computer Science, FO.R.T.H. is actively involved in the creation and evolution of the regional healthcare network of Crete. In this context, a web-based environment that allows healthcare personnel to collaborate with their peers regardless of their actual geographic location has been developed. Healthcare related collaboration will be facilitated through a number of integrated web-based services such as electronic mail, ICnet postings, annotations, and on-line collaboration.
In-building wideband multipath characteristics at 2.5 and 60 GHz (2003)

This paper contains measured data for 2.5 and 60 GHz in-building partition loss. Path loss measurements were recorded using a broadband sliding correlator channel sounder which recorded over 39000 power delay profiles (PDP) in 22 separate locations in a modern office building. Transmitters and receivers were separated by distances ranging from 3.5 to 27.4 meters, and were separated by a variety of obstructions, in order to emulate future single-cell-per-room wireless networks. These measurements may aid in the development of future in-building wireless networks in the unlicensed 2.4 GHz and 60 GHz bands.
Non‐vacuum deposition of Cu(In,Ga)Se<sub>2</sub> absorber layers from binder free, alcohol solutions (2012)

ABSTRACT Non‐vacuum methods for Cu(In,Ga)Se 2 (CIGS) absorber deposition have gained wide interest because of their inherent cost and energy saving potential. Here, a solution‐based processing route for CIGS absorber layers is presented that employs binder‐free solutions of metal salts in non‐toxic, alcohol solvents. Despite the low‐boiling‐point nature of the employed solvents, a residual carbon‐rich layer is observed between the CIGS and metal back contact. Based on comprehensive investigations by scanning electron microscopy, energy‐/wavelength dispersive X‐ray spectroscopy, X‐ray fluorescence, X‐ray diffraction, thermogravimetric analysis, differential thermal analysis, and extended X‐ray absorption fine structure spectroscopy, a formation reaction mechanism through intermediate metal–organic complexes is proposed. In this route, the CIGS layer is formed in selenium atmosphere via a gradual decomposition of the carbon‐rich layer comprising carboxylic chelate complexes of metals. A compositional gradient occurs in the CIGS absorber, whereas a significant amount of metals remains in the carbon‐rich layer. The incorporation of Ga into CIGS is affected by the initial salt concentration and the selenization temperature. Fabricated solar cells exhibit active area efficiencies of up to 7.7% on 0.3 cm 2 area without anti‐reflection coating, which is among the highest reported efficiencies for solar cells from a solution process with non‐explosive gases or solvents.

The Emergence of Veterinary Oaths: Social, Historical, and Ethical Considerations (2012)

Abstract Veterinary oaths are public declarations sworn by veterinarians, usually when they enter the profession. As such, they may reflect professional and social concerns. Analysis of contemporary veterinary oaths may therefore reveal their ethical foundations. The objective of this article is to contextualize the ethical content of contemporary oaths, in terms of the origin and development of veterinary medicine and wider societal changes such as the intensification of farming and the rise of animal welfare. This informs a comparison of oaths from the United States, Canada, the United Kingdom, and Brazil. This analysis suggests some ways in which the oaths might be developed to better reflect contemporary societal values.
Local and Systemic Protection by Synthetic Polyanionic Interferon Inducers in mice against Intranasal Vesicular Stomatitis Virus (1969)

SUMMARY The effects of the synthetic polyanionic interferon inducers maleic acid/divinyl ether copolymer (MA/DVE) and polyinosinic/polycytidylic acid (polyrI/polyrC) were studied in mice challenged intranasally with vesicular stomatitis virus. Young (14-day or 24-day) animals were used. Either local (intranasal) or systemic (intraperitoneal) treatment protected significantly against virus infection. Optimal local protection was given by 40 μg. of polyrI/polyrC instilled 4 hr before virus challenge. Intraperitoneal MA/DVE exerted a more durable effect lasting for at least 10 days, and polyrI/polyrC proved to be active when applied several days after inoculation of virus. PolyrI/polyrC treatment started after virus in the brain had reached maximum concentration retarded progression of the disease, but when delayed until clinical signs of illness occurred, polyrI/polyrC treatment was not effective. The protective activity of MA/DVE and polyrI/polyrC injected intraperitoneally against virus infection at a distant site suggested the mediation by a systemic antivirus state, presumably due to interferon production.

Intensive clinic follow-up for outpatients with CHF in HF clinic can improve evidence-based treatment, reduce the readmission and death rate, improve quality of life and save hospital cost.
Detection of the bcr/abl gene in bone marrow macrophages in CML and alterations during interferon therapy—a fluorescencein situ hybridization study on trephine biopsies (1998)

A fluorescence in situ hybridization (FISH) study was performed on trephine biopsies of the bone marrow in chronic myelogenous leukaemia (CML) to evaluate the bcr/abl translocation in macrophages before and during interferon (IFN) therapy. Mature macrophages and osteoclasts were identified by the monoclonal antibody PG-M1, which recognizes a fixative-resistant epitope of the CD68 molecule. In contrast to a control group, in 145 of 479 (30 per cent) macrophages of the CML bone marrow, a positive fusion signal was found, together with corresponding translocation sites in the surrounding myeloid cells. In patients following IFN treatment for approximately 12 months and with haematological/cytogenetic remission by clinical standards, this number was reduced to 10 of 136 (9 per cent) macrophages. In addition, the few multinucleated osteoclasts of the untreated CML bone marrow displayed positive translocation spots. This finding supports the hypothesis that stromal macrophages and osteoclasts are of haematogenic stem cell origin. Moreover, clinical remission and reduction of bcr/abl-positive macrophages under IFN therapy lend support to the hypothesis that the presence of malignant stromal macrophages may contribute to the selective expansion of leukaemic precursors and the suppression of normal haematopoiesis in CML.
Cross-Coupling Reaction of Alkyl- or Arylboronic Acid Esters with Organic Halides Induced by Thallium(I) Salts and Palladium-Catalyst (1989)

Abstract The cross-coupling reaction of alkylboronic acid esters with 1-alkenyl- or aryl halides is successfully catalyzed by PdCl2(dppf) or Pd(PPh3)4 in the presence of thallium(I) hydroxide or carbonate to give the corresponding alkenes or arenes in good yields. The coupling reaction of arylboronic acid esters with aryl halides under similar conditions to provide biaryls is also described.
Biochemical Perspectives in Tissue Culture for Crop Improvement (2024)

In modern agriculture only about 150 plant species are extensively cultivated. During the last 40 years major improvements in the world food situation has been achieved, due in large part to expanded production and enhanced yields. 1 , 2 The growth in agricultural production has been broad based, increasing at a compound annual rate of 2.8% between 1950 and 1980. 3 Thus more people today have a reasonably adequate food supply than at any time in history. Nevertheless, there are serious food problems today, particularly in sub-Saharan Africa, and a combination of positive and negative trends has created great uncertainty over the future of the world food economy. 4 However, it is clear that benefits will accrue through technological improvements in production, processing, and distribution of food crops. 1 , 2
Tuning Oxygen Reduction Reaction Activity via Controllable Dealloying: A Model Study of Ordered Cu<sub>3</sub>Pt/C Intermetallic Nanocatalysts (2012)

A promising electrocatalyst prototype of low Pt mole fraction, intermetallic nanoparticles of Cu(3)Pt, has been prepared using a simple impregnation-reduction method, followed by a post heat-treatment. Two dealloying methods (electrochemical and chemical) were implemented to control the atomic-level morphology and improve performance for the oxygen reduction reaction (ORR). The morphology and elemental composition of the dealloyed nanoparticles were characterized at angstrom resolution using an aberration-corrected scanning transmission electron microscope equipped with an electron energy loss spectrometer. We found that the electrochemical dealloying method led to the formation of a thin Pt skin of ca. 1 nm in thickness with an ordered Cu(3)Pt core structure, while chemical leaching gave rise to a "spongy" structure with no ordered structure being preserved. A three-dimensional tomographic reconstruction indicated that numerous voids were formed in the chemically dealloyed nanoparticles. Both dealloying methods yielded enhanced specific and mass activities toward the ORR and higher stability relative to Pt/C. The spongy nanoparticles exhibited better mass activity with a slightly lower specific activity than the electrochemically dealloyed nanoparticles after 50 potential cycles. In both cases, the mass activity was still enhanced after 5000 potential cycles.
Breast cancer cell lines: friend or foe? (2003)

The majority of breast cancer research is conducted using established breast cancer cell lines as in vitro models. An alternative is to use cultures established from primary breast tumours. Here, we discuss the pros and cons of using both of these models in translational breast cancer research.

Three novel antibiotic marker cassettes for gene disruption and marker switching inSchizosaccharomyces pombe (2005)

The ease of construction of multiple mutant strains in Schizosaccharomyces pombe is limited by the number of available genetic markers. We describe here three new cassettes for PCR-mediated gene disruption that can be used in combination with commonly used fission yeast markers to make multiple gene deletions. The natMX6, hphMX6 and bleMX6 markers give rise to resistance towards the antibiotics nourseothricin (NAT), hygromycin B and phleomycin, respectively. The cassettes are composed of exogenous sequences to increase the frequency of integration at targeted loci, and have a structure similar to the commonly used pFA6a-kanMX6 modular plasmid system. This allows a simple exchange of the kanMX6 marker in existing strains with any of the three new cassettes. Alternatively, oligonucleotide primers designed for the modular kanMX6 cassettes can be used to make the transforming PCR fragments for gene disruption. We illustrate the construction of a mutant strain with six independent gene disruptions, using the novel antibiotic cassettes in combination with existing genetic markers.
Drilling Stuck Pipe Prediction in Iranian Oil Fields: An Artificial Neural Network Approach (2010)

Stuck pipe is one of the most serious drilling problems, estimated to cost the petroleum industry hundreds of millions of dollars annually. One way to avoid stuck pipe risks is to predict the stuck pipe with the available drilling parameters which can be employed to modify drilling variables. In this work, Artificial Neural Network (ANN) was used for stuck pipe prediction according to the fact that this method is applicable when relationships of parameters are too complicated. Based on the drilling fluid condition from one of the Iranian oil fields, stuck pipe instances were divided into static and dynamic types. The results of this study show more than 90% accuracy for stuck pipe prediction in the investigated oilfield. The methodology presented in this paper enables the Iranian drilling industry to estimate the risk of stuck pipe occurrenc during the well planning procedure.
Diversity and population status of Ursus arctos in Pakistan (2012)

Brown bears (Ursus arctos) are poorly studied in Pakistan and historically, it was found in the entire range of the mountains of northern Pakistan, in a total area of 150,000 km2, but in the past 50 years its population size are declining and have gone extinct from some areas. Brown bears are now distributed over 3 major mountain ranges and 4 intermountain highlands. Bears are legally protected, however, and recently designated as critically endangered in IUCN’s Red List of Mammals of Pakistan. Seven populations probably persist in the Himalaya, Karakoram, and Hindu Kush ranges; the Deosai Plateau in western Himalaya hosts the only stable population. Seven national parks and many wildlife sanctuaries and game reserves, which provide legal protection to bears, have been established in the northern mountains of Pakistan. Growing human population, expanding infrastructure, increasing number of livestock, and increasing dependency on natural resources, particularly alpine pastures, are key threats. Poaching for its commercial parts and for cubs and growing unmanaged tourism also contribute to population decline. The population has become conservation dependent, and actions like effective management of protected areas, better management of natural resources, and environmental education need immediate attention.
Blue Light-Induced Phototropism of Inflorescence Stems and Petioles is Mediated by Phototropin Family Members phot1 and phot2 (2009)

Phototropin family photoreceptors, phot1 and phot2, in Arabidopsis thaliana control the blue light (BL)-mediated phototropic responses of the hypocotyl, chloroplast relocation movement and stomatal opening. Phototropic responses in dark-grown tissues have been well studied but those in de-etiolated green plants are not well understood. Here, we analyzed phototropic responses of inflorescence stems and petioles of wild-type and phototropin mutant plants of A. thaliana. Similar to the results obtained from dark-grown seedlings, inflorescence stems and petioles in wild-type and phot2 mutant plants showed phototropic bending towards low fluence BL, while in phot1 mutant plants, a high fluence rate of BL was required. phot1 phot2 double mutant plants did not show any phototropic responses even under very high fluence rates of BL. We further studied the photoreceptive sites for phototropic responses of stems and petioles by partial tissue irradiation. The whole part of the inflorescence stem is sensitive to BL and shows phototropism, but in the petiole only the irradiated abaxial side is sensitive. Similar to dark-grown etiolated seedlings, phot1 plays a major role in phototropic responses under weak light, but phot2 functions under high fluence rate conditions in green plants.
18S Ribosomal DNA-Based PCR for Diagnosis of <i>Trichomonas vaginalis</i> (2000)

Trichomonas vaginalis remains the most common sexually transmitted parasite in the world and is considered a major risk factor in the transmission of the human immunodeficiency virus. A PCR technique using primers targeting a specific region of the 18S rRNA gene of T. vaginalis was developed. The PCR test was standardized using 15 reference strains, giving a single product of 312 bp in all strains. No amplification was observed when DNA from related organisms or human DNA was used as a target. The test was evaluated on 372 vaginal swab specimens and 361 urine samples from women attending infertility and obstetric clinics at two separate hospitals in Lima, Peru. Compared to T. vaginalis culture, the overall sensitivity and specificity of PCR of vaginal swab samples was 100% and 98%, respectively. The PCR of urine samples was 100% sensitive and 99.7% specific compared to culture of vaginal swab, but the sensitivity drops to 83.3% when compared to PCR of vaginal swabs. All culture-positive samples were found to be positive by PCR in either urine or vaginal secretion. None of the PCR-negative samples were positive by culture. The origin of the amplification was confirmed by digestion of PCR products with HaeIII. This PCR assay, which is easy to perform and has a high sensitivity and specificity, should be useful for routine diagnosis of T. vaginalis infection.
