Transcriptome Analysis of a Phenol-Producing Pseudomonas putida S12 Construct: Genetic and Physiological Basis for Improved Production (2007)

The unknown genetic basis for improved phenol production by a recombinant Pseudomonas putida S12 derivative bearing the tpl (tyrosine-phenol lyase) gene was investigated via comparative transcriptomics, nucleotide sequence analysis, and targeted gene disruption. We show upregulation of tyrosine biosynthetic genes and possibly decreased biosynthesis of tryptophan caused by a mutation in the trpE gene as the genetic basis for the enhanced phenol production. In addition, several genes in degradation routes connected to the tyrosine biosynthetic pathway were upregulated. This either may be a side effect that negatively affects phenol production or may point to intracellular accumulation of tyrosine or its intermediates. A number of genes identified by the transcriptome analysis were selected for targeted disruption in P. putida S12TPL3. Physiological and biochemical examination of P. putida S12TPL3 and these mutants led to the conclusion that the metabolic flux toward tyrosine in P. putida S12TPL3 was improved to such an extent that the heterologous tyrosine-phenol lyase enzyme had become the rate-limiting step in phenol biosynthesis.
Whitepaper of NEWS 2015 Shared Task on Machine Transliteration (2015)

Transliteration is defined as phonetic translation of names across languages. Transliteration of Named Entities (NEs) is necessary in many applications, such as machine translation, corpus alignment, cross-language IR, information extraction and automatic lexicon acquisition. All such systems call for high-performance transliteration, which is the focus of shared task in the NEWS 2015 workshop. The objective of the shared task is to promote machine transliteration research by providing a common benchmarking platform for the community to evaluate the state-of-the-art technologies.
Novel predictive assay for contact allergens using human skin explant cultures. (1996)

Contact allergens sensitize the immune system by the binding to and subsequent activation of Langerhans cells (LCs), the antigen-presenting cells of the skin. At present, new chemicals are usually tested for their contact allergenicity in animal models. To develop an animal-replacing predictive in vivo assay for the identification of potential contact allergens, we compared the effects of epicutaneous application of six known contact allergens, five known irritants and two dermatologically inactive chemicals on LCs in skin biopsy cultures from seven healthy donors. Immunohistochemical analysis of cryostat sections of all the biopsies treated with contact allergens showed 1) a large reduction in the number of LCs in epidermis, as evaluated by a decrease in human leukocyte antigens (HLA)-DR-expressing cells, and CD1a-expressing cells and 2) accumulation of the remaining LCs at the epidermal-dermal junction. In contrast, the irritants, inactive chemicals, and solvents did not induce these changes. Morphometrical analysis indicated that the contact allergen-induced reduction in the number of HLA-DR+ and CD1a+ LCs per millimeter of epidermis was significant and was dependent on the concentration of the contact allergens. Flow cytometric analysis of isolated epidermal cells confirmed the immunohistochemical findings. In combination, these results suggest that the culture of ex vivo human skin explants provides a promising model to predict potential allergenicity of newly produced chemical compounds and can therefore replace current animal models.
Three N-terminal domains of beta-1,3-glucanase A1 are involved in binding to insoluble beta-1,3-glucan (1992)

Limited proteolysis of beta-1,3-glucanase A1 by three different proteases, trypsin, chymotrypsin, and papain, gave three major active fragments. The sizes of the three major fragments generated by each protease treatment were identical to those of beta-1,3-glucanase A2, A3, and A4 detected in both the culture supernatant of Bacillus circulans WL-12 and the periplasmic space of Escherichia coli carrying a cloned glcA gene. These results indicate a four-domain structure for the enzyme. At the N terminus of the glucanase, duplicated segments of approximately 100 amino acids were observed. N-terminal amino acid sequence analysis revealed that the active fragments with sizes corresponding to those of A2 and A3 lack the first segment (domain) and both duplicated segments (domains), respectively. The fragment corresponding to A4 lacks both duplicated segments and the following ca. 120-amino-acid region. By losing the first, second, and third (corresponding to the segment of 120 amino acids) domains, beta-1,3-glucanase progressively lost the ability to bind to pachyman, beta-1,3-glucan. An active fragment which did not have the three N-terminal domains did not show significant binding to pachyman. Thus, all three N-terminal domains contribute to binding to beta-1,3-glucan, and the presence of three domains confers the highest binding activity on the glucanase. The loss of these binding domains remarkably decreased pachyman-hydrolyzing activity, indicating that the binding activity is essential for the efficient hydrolysis of insoluble beta-1,3-glucan.
Cloning and expression of the gene for the vitamin B12 receptor protein in the outer membrane of Escherichia coli (1985)

The transport of cyanocobalamin (vitamin B12) in cells of Escherichia coli is dependent on a receptor protein (BtuB protein) located in the outer membrane. A 9.1-kilobase pair BamHI fragment carrying the btuB gene was cloned from a specialized transducing phage into multicopy plasmids. Insertions of transposon Tn1000 which prevented production of the receptor localized btuB to a 2-kilobase pair region. Further subcloning allowed isolation of this region as a 2.3-kilobase pair Sau3A fragment. The BtuB+ plasmids were shown by maxicell analysis to encode a polypeptide with a molecular weight of 66,000 in the outer membrane. This polypeptide was missing in cells with Tn1000 insertions in btuB and was reduced in amount upon growth of plasmid-bearing cells in repressing concentrations of vitamin B12. Several Tn1000 insertions outside the 5' end of the coding region exhibited reduced production of receptor. A deletion at the 3' end of btuB resulted in formation of an altered receptor. Amplified production of this polypeptide was associated with increased levels of binding of the receptor's ligands (vitamin B12 and phage BF23), increased rates of vitamin B12 uptake, and altered susceptibility to the group E colicins. Deficiency in various major outer membrane proteins did not affect production of the btuB product, and the amplified levels of this protein partially reversed the tolerance to E colicins seen in these mutants.
Radiographic evidence of disease progression in methotrexate treated and nonmethotrexate disease modifying antirheumatic drug treated rheumatoid arthritis patients: a meta-analysis. (1992)

Methotrexate (MTX) has proven to be efficacious in the treatment of rheumatoid (RA), but it remains to be proven whether it can slow disease progression, as determined radiographically, in comparison with other disease modifying antirheumatic drugs (DMARD). We performed a meta-analysis of the available data to answer this question. A literature search, including abstracts, was conducted and inclusion criteria developed (description of patients, accountability of patients, inclusion of a control group of patients, specified radiographic endpoint, and appropriate reading of the radiographs). Publications were scored on a scale of 0 to 5 with a score > or = 3 required for inclusion in the study. For abstracts selected, additional data were obtained directly from the investigators. Data for 353 MTX treated and 205 non-MTX-DMARD treated patients with RA were gathered. Not all publications used the same scoring system, so some assumptions were required to analyze the combined data. Only the erosion score was included since not all publications included a reading of the joint space. All scores were transformed into Sharp scores (Arthritis Rheum 1985;28:1449), including the important contributions of 3 Larsen scored publications. Finally a monthly rate of disease progression was computed. Several comparisons were made. Overall, the rates of disease progression were similar for MTX and non-MTX-DMARD treated patients with RA. The non-MTX-DMARD treated patients with RA were separated into a group treated with gold salts (oral or parenteral) and a group treated with azathioprine with each group compared to the MTX treated patients. MTX had slower rates of disease progression than azathioprine, (rates 0.004 vs 0.012) but not slower rates than gold salts (0.008 vs 0.008). Despite its efficacy, the possible role of MTX in slowing disease progression more than other DMARD, as determined radiographically, appears to be evident only when compared to azathioprine.
Strategyproof Mechanisms for Ad Hoc Network Formation (2003)

Agents in a peer-to-peer system typically have incentives to influence its network structure, either to reduce their costs or increase their ability to capture value. The problem is compounded when agents can join and leave the system dynamically. This paper proposes three economic mechanisms that offset the incentives for strategic behavior and facilitate the formation of networks with desirable global properties.
Monolithic Integration of GaAs/InGaAs Lasers on Virtual Ge Substrates via Aspect-Ratio Trapping (2009)

GaAs/InGaAs quantum-well lasers have been demonstrated by metallorganic chemical vapor deposition on virtual Ge substrates on Si via aspect-ratio trapping (ART) and epitaxial lateral overgrowth (ELO). Laser-structure growth is achieved in two steps: The first step is growing uncoalesced defect-free Ge stripes on a trench-patterned silicon substrate via ART, whereby the misfit defects originating from the Ge/Si interface are trapped by laterally confining sidewalls. Defects arising from above the film are reduced by using an optimized ELO process followed by chemical mechanical polishing to provide a planar Ge surface. The second step is overgrowing a GaAs/InGaAs laser structure on the virtual Ge substrate. A number of GaAs/Ge integration issues, including Ge autodoping and antiphase domain defects in GaAs, have been overcome. Despite unoptimized laser structures with high series resistance and large threshold current densities, pulsed room-temperature lasing at a wavelength of 980 nm has been demonstrated using a combination of ART and ELO. This technique is very promising for the achievement of reliable GaAs-based optoelectronic devices on Si.
Immobilization of immunoglobulins onto surface-treated and untreated polystyrene beads for radioimmunoassays. (1990)

The immunoreactivity of anti-triiodothyronine (anti-T3) IgG, pretreated at acidic pH and adsorbed onto polystyrene beads, was significantly greater than that determined for native anti-T3 IgG immobilized at optimum pH 3.5. Acidic-pH-pretreated IgG, adsorbed at pH 7.0 onto ethanol-treated beads, had less immunoreactivity than that on untreated beads and gave values similar to those of native IgG adsorbed onto activated beads at pH 9.6. The rate of immobilization onto treated beads was significantly greater than onto untreated ones, and the binding was reproducible (intra- and inter-batch coating CV, 3.7-4.6% and 7.2%, respectively) and very resistant to successive washings. A post-washing incubation in 10 mg/L bovine serum albumin solution was required to eliminate the decreased immobilized immunoreactivity caused by some washing reagents. For solid-phase radioimmunoassays of T3, 40% less antibody was needed when acidic-pH-pretreated IgG was adsorbed onto untreated beads or when native IgG was adsorbed onto ethanol-treated beads, in comparison with native IgG adsorbed onto untreated beads. Results and assay characteristics with such beads were comparable with results for solid-phase and liquid-phase polyethylene glycol assay of T3.
AAV2 Gene Therapy Readministration in Three Adults with Congenital Blindness (2012)

Demonstration of safe and stable reversal of blindness after a single unilateral subretinal injection of a recombinant adeno-associated virus (AAV) carrying the RPE65 gene (AAV2-hRPE65v2) prompted us to determine whether it was possible to obtain additional benefit through a second administration of the AAV vector to the contralateral eye. Readministration of vector to the second eye was carried out in three adults with Leber congenital amaurosis due to mutations in the RPE65 gene 1.7 to 3.3 years after they had received their initial subretinal injection of AAV2-hRPE65v2. Results (through 6 months) including evaluations of immune response, retinal and visual function testing, and functional magnetic resonance imaging indicate that readministration is both safe and efficacious after previous exposure to AAV2-hRPE65v2.
Effects and Mechanism of Atmospheric-Pressure Dielectric Barrier Discharge Cold Plasmaon Lactate Dehydrogenase (LDH) Enzyme (2015)

Proteins are carriers of biological functions and the effects of atmospheric-pressure non-thermal plasmas on proteins are important to applications such as sterilization and plasma-induced apoptosis of cancer cells. Herein, we report our detailed investigation of the effects of helium-oxygen non-thermal dielectric barrier discharge (DBD) plasmas on the inactivation of lactate dehydrogenase (LDH) enzyme solutions. Circular dichroism (CD) and dynamic light scattering (DLS) indicate that the loss of activity stems from plasma-induced modification of the secondary molecular structure as well as polymerization of the peptide chains. Raising the treatment intensity leads to a reduced alpha-helix content, increase in the percentage of the beta-sheet regions and random sequence, as well as gradually decreasing LDH activity. However, the structure of the LDH plasma-treated for 300 seconds exhibits a recovery trend after storage for 24 h and its activity also increases slightly. By comparing direct and indirect plasma treatments, plasma-induced LDH inactivation can be attributed to reactive species (RS) in the plasma, especially ones with a long lifetime including hydrogen peroxide, ozone, and nitrate ion which play the major role in the alteration of the macromolecular structure and molecular diameter in lieu of heat, UV radiation, and charged particles.
Modulation of Polyketide Synthase Activity by Accessory Proteins During Lovastatin Biosynthesis (1999)

Polyketides, the ubiquitous products of secondary metabolism in microorganisms, are made by a process resembling fatty acid biosynthesis that allows the suppression of reduction or dehydration reactions at specific biosynthetic steps, giving rise to a wide range of often medically useful products. The lovastatin biosynthesis cluster contains two type I polyketide synthase genes. Synthesis of the main nonaketide-derived skeleton was found to require the previously known iterative lovastatin nonaketide synthase (LNKS), plus at least one additional protein (LovC) that interacts with LNKS and is necessary for the correct processing of the growing polyketide chain and production of dihydromonacolin L. The noniterative lovastatin diketide synthase (LDKS) enzyme specifies formation of 2-methylbutyrate and interacts closely with an additional transesterase (LovD) responsible for assembling lovastatin from this polyketide and monacolin J.
Aberrant expression of VEGF-C is related to grade of cervical intraepithelial neoplasia (CIN) and high risk HPV, but does not predict virus clearance after treatment of CIN or prognosis of cervical cancer (2006)

VEGF-C is an early marker of cervical carcinogenesis, with linearly increasing expression starting from low grade CIN. VEGF-C expression is closely related to HR-HPV in cervical lesions, probably because of its p53 independent upregulation by the E6 oncoprotein of HR-HPV.
Analysis of antibodies and other large glycoproteins in the mass range of 150,000-200,000 daltons by electrospray ionization mass spectrometry (1992)

The analytical applicability of electrospray ionization mass spectrometry (ESIMS) to large glycoproteins in the molecular weight (MW) range of 150,000-200,000 was demonstrated. Multiply charged ions (charge state as high as 150+) of several typical macrosized glycoproteins of immunological significance were generated by pneumatically-assisted electrospray (ionspray) and their masses measured on a quadrupole mass spectrometer having a mass-to-charge (m/z) range of 2400. The resolution of the quadrupole instrument was insufficient to resolve the glycocomposition microheterogeneities in the MW range studied. Nevertheless, the average MWs of three immunoglobulin G (IgG) class murine monoclonal antibodies, anti-(human alpha 1-antitrypsin) (148,484 +/- 4), anti-(human alpha 1-acid glycoprotein) (149,599 +/- 12) and anti-(beta-galactosidase) (component I, 150,544 +/- 10, and component II, 151,496 +/- 17), and human alpha 2-macroglobulin monomer (186,100 +/- 100), and human complement component C4 (196,863 +/- 29) were still determined from the fused peak profiles of their constituent glyco components (the errors given reflect the measurement precisions of the simultaneous multichannel MW determinations). The difference between the measured average MW and the unmodified sequence MW was used to assess the degree of post-transitional modification in human alpha 2-macroglobulin (13.6%) and human complement component C4 (5.3%). For the large glycoproteins studied here, glycosylation did not appear to seriously affect the effectiveness of the electrospray ionization; up to 70% of their full charge-retaining capacities were fulfilled under the usual experimental conditions. These results show that ESIMS is capable of providing analytically useful information for macrosized proteins.
PIK3CA-activating mutations and chemotherapy sensitivity in stage II–III breast cancer (2008)

PIK3CA mutations are not associated with altered sensitivity to preoperative anthracycline-based or taxane-based chemotherapies in ER-positive and ER-negative breast tumors. In this study, PIK3CA mutation was associated with a decreased rate of node-positive disease, particularly among ER-positive tumors.
Biomarkers: A Definite Plus in Pneumonia (2009)

During the past few years, biomarkers have emerged as an indispensible tool in the diagnosis of pneumonia. To find an ideal diagnostic biomarker for pneumonia is not an easy task. Not only should it allow an early diagnosis of the condition, but it should also allow differential diagnosis from other noninfectious conditions. Ongoing research is being done in this field so as to put an array of biomarkers at the disposal of doctors to improve the diagnosis of pneumonia when patients present to them with cough or nonspecific symptoms which could easily be misinterpreted as symptoms of other conditions. Procalcitonin and soluble triggering receptor expressed on myeloid cells-1 have emerged as reliable diagnostic markers in pneumonia, and are better when compared to other markers, namely, C-reactive protein, leukocyte count, and proinflammatory cytokines. Many other biomarkers are being studied for their probable use in diagnosing pneumonia but have yet to prove their benefit.
Efficient Functionalization of Carbon Nanotubes with Porphyrin Dendrons via Click Chemistry (2009)

The attempt to decorate carbon nanotubes with organic molecules as a powerful means to form new functional materials has attracted broad attention in the scientific community. Here, we report the functionalization of single-walled carbon nanotubes (SWNTs) with zinc porphyrins (ZnP) using very mild conditions to afford a series of SWNTs-ZnP (1 and 2) electron donor-acceptor conjugates. Owing to the presence of either one or two ZnP, introduced via "click chemistry", different absorption cross sections were realized. Important in this context is that the covalent linkages between SWNT and ZnP were corroborated by monitoring the diagnostic signature of the nitrogen atoms as part of the formed triazole ring by X-ray photoelectron spectroscopy (XPS). The resulting SWNTs-ZnP 1 and 2 were fully characterized. This characterization was complemented by a full-fledged investigation of their electrochemical and photophysical properties. In particular, appreciably strong electronic coupling between the photo- and electroactive constituents (i.e., SWNT and ZnP) led to rapid excited-state deactivation of ZnP via charge transfer to the nanotubes. Here, the different absorption cross sections throughout the visible part of the solar spectrum turned out to be valuable in enhancing the overall light-harvesting features. Upon photoexcitation, for both SWNTs-ZnP 1 and 2, radical ion pair states (i.e., reduced SWNT and oxidized ZnP) are formed. The charge-separated states decay to regenerate the singlet ground state with lifetimes of 820 and 200 ps for 1 and 2, respectively.
Plasma A 42 and A 40 as markers of cognitive change in follow-up: a prospective, longitudinal, population-based cohort study (2010)

Low or decreasing plasma Aβ42 during the follow-up is associated with cognitive decline. Serial measurement of plasma Aβ42 may be useful in the detection of the subjects who are at risk for cognitive decline.
Bandwidth extension of narrowband speech for low bit-rate wideband coding (2002)

Wireless telephone speech is usually limited to the 300-3400 Hz band, which reduces its quality. There is thus a growing demand for wideband speech systems that transmit from 50 Hz to 8000 Hz. This paper presents an algorithm to generate wideband speech from narrowband speech using as low as 500 bit/s of side information. The 50-300 Hz band is predicted from the narrowband signal. A source-excitation model is used for the 3400-8000 Hz band, where the excitation is extrapolated at the receiver, and the spectral envelope is transmitted. Though some artifacts are present, the resulting wideband speech has enhanced quality compared to narrowband speech.
The Na<sup>+</sup>/H<sup>+</sup> Exchanger SM-20220 Attenuates Ischemic Injury in in vitro and in vivo Models (2001)

The aim of this study is to clarify whether the activation of a Na(+)/H(+) exchanger (NHE) is tightly concerned with neuronal and glial cell injury induced by ischemia using a selective NHE inhibitor, SM-20220 (N-(aminoiminomethyl)-1-methyl-1H-indole-2-carboxamide methanesulfonate). Two hours of hypoxia followed by 24 h of reoxygenation induced lactate dehydrogenase (LDH) release, a marker of cell membrane damage, in cultured neurons and glia derived from rats. SM-20220 significantly reduced LDH release in both cells in a concentration-dependent manner, and this effect was statistically significant at concentrations of more than 10(-8) mol/l for neurons and 10(-7) mol/l for glia. A standard NHE inhibitor, 5-(N-ethyl-N-isopropyl)-amiloride, also reduced LDH release in neurons at concentrations of more than 10(-7) mol/l. In a rat transient middle cerebral artery occlusion model, intravenous infusion of SM-20220 reduced cerebral infarction when the serum concentration of SM- 20220 was maintained at about 10(-7) mol/l. These results suggest that the activation of the NHE plays an important role in ischemic neuronal and glial cell injury, and NHE inhibitor may have good therapeutic value for the treatment of ischemic stroke.
