[Immunobiological properties and therapeutic effectiveness of preparations from Klebsiella bacteriophages]. (1992)

The purified preparations of Klebsiella bacteriophages, viz. the monovalent preparation of K. pneumoniae bacteriophage and the polyvalent bacteriophage preparation for the treatment of infections caused by K. ozaenae, K. rhinoscleromatis scleromatis and K. pneumoniae sensu lato, have been obtained. The bacteriophage preparations have proved to be nontoxic and safe for laboratory animals after the intraperitoneal injection of these preparations followed by the pathomorphological study of the internal organs of the animals. The clinical study of the newly developed bacteriophage preparations in the course of the treatment of purulent inflammatory diseases in 109 patients has revealed that the preparations are not reactogenic and exhibit sufficient effectiveness in the therapy of ozena, rhinoscleroma and Klebsiella infections with different localization of the infectious process.
Documents classification by using ontology reasoning and similarity measure (2010)

Ontology-based documents classification method is introduced to solve the problem of classifier training and not considering semantic relations between words in traditional Machine Learning algorithms. However, previous work on ontology-based documents classification have some drawbacks on precision and run-time performance. In order to solve these problems, this paper proposes a novel ontology-based documents classification method by using ontology reasoning and similarity measure. Firstly, weighted terms set are extracted from documents, and categories are represented by ontologies; then the lowest concepts for each ontology is computed by using ontology reasoning techniques; next similarity score between documents and ontology is computed by using Google Distance measure; finally, web documents are assigned to categories according to the similarity score. Experimental results show our method is effective when comparing with the current ontology-based classification method, especially in the delicate classification evaluation, and the run-time performance is also better.
Cancer Vaccines Targeting Carbohydrate Antigens (2006)

Cancer carbohydrate antigens have been surprisingly potent targets for immune recognition and attack by antibodies, both because of their abundance at the cell surface and their immunogenicity. Antibodies are ideally suited for eradicating pathogens from the bloodstream and from early tissue invasion. Passively administered and vaccine induced antibodies have accomplished this, eliminating circulating tumor cells and systemic or intraperitoneal micrometastases in a variety of preclinical models. A series of carbohydrate cancer cell-surface differentiation antigens have now been identified and synthesized. Antibodies against each can be induced in the majority of vaccinated patients using KLH conjugate vaccines with a potent saponin immunological adjuvant. Polyvalent vaccines will probably be required due to tumor cell heterogeneity, heterogeneity of the human immune response and the correlation between overall antibody titer against tumor cells and antibody effector mechanisms. Trials testing the clinical impact of these polyvalent vaccines in the adjuvant setting are planned for the near future.
Analysis of Antioxidant Activities of Common Vegetables Employing Oxygen Radical Absorbance Capacity (ORAC) and Ferric Reducing Antioxidant Power (FRAP) Assays:  A Comparative Study (2002)

A total of 927 freeze-dried vegetable samples, including 111 white cabbages, 59 carrots, 51 snap beans, 57 cauliflower, 33 white onions, 48 purple onions, 130 broccoli, 169 tomatoes, 25 beets, 88 peas, 88 spinach, 18 red peppers, and 50 green peppers, were analyzed using the oxygen radical absorption capacity (ORAC) and ferric reducing antioxidant capacity (FRAP) methods. The data show that the ORAC and FRAP values of vegetable are not only dependent on species, but also highly dependent on geographical origin and harvest time. The two antioxidant assay methods, ORAC and FRAP, also give different antioxidant activity trends. The discrepancy is extensively discussed based on the chemistry principles upon which these methods are built, and it is concluded that the ORAC method is chemically more relevant to chain-breaking antioxidants activity, while the FRAP has some drawbacks such as interference, reaction kinetics, and quantitation methods. On the basis of the ORAC results, green pepper, spinach, purple onion, broccoli, beet, and cauliflower are the leading sources of antioxidant activities against the peroxyl radicals.
Using topic models for Twitter hashtag recommendation (2013)

Since the introduction of microblogging services, there has been a continuous growth of short-text social networking on the Internet. With the generation of large amounts of microposts, there is a need for effective categorization and search of the data. Twitter, one of the largest microblogging sites, allows users to make use of hashtags to categorize their posts. However, the majority of tweets do not contain tags, which hinders the quality of the search results. In this paper, we propose a novel method for unsupervised and content-based hashtag recommendation for tweets. Our approach relies on Latent Dirichlet Allocation (LDA) to model the underlying topic assignment of language classified tweets. The advantage of our approach is the use of a topic distribution to recommend general hashtags.

Improving the performance of colloidal quantum-dot-sensitized solar cells (2009)

Solar cells based on a mesoporous structure of TiO2 and the polysulfide redox electrolyte were prepared by direct adsorption of colloidal CdSe quantum dot light absorbers onto the oxide without any particular linker. Several factors cooperate to improve the performance of quantum-dot-sensitized solar cells: an open structure of the wide bandgap electron collector, which facilitates a higher covering of the internal surface with the sensitizer, a surface passivation of TiO2 to reduce recombination and improved counter electrode materials. As a result, solar cells of 1.83% efficiency under full 1 sun illumination intensity have been obtained. Despite a relatively large short circuit current (J(sc) = 7.13 mA cm(-2)) and open circuit voltage (V(oc) = 0.53 V), the colloidal quantum dot solar cell performance is still limited by a low fill factor of 0.50, which is believed to arise from charge transfer of photogenerated electrons to the aqueous electrolyte.
Packet Switched vs. Time Multiplexed FPGA Overlay Networks (2006)

Dedicated, spatially configured FPGA interconnect is efficient for applications that require high throughput connections between processing elements (PEs) but with a limited degree of PE interconnectivity (e.g. wiring up gates and datapaths). Applications which virtualize PEs may require a large number of distinct PE-to-PE connections (e.g. using one PE to simulate 100s of operators, each requiring input data from thousands of other operators), but with each connection having low throughput compared with the PE's operating cycle time. In these highly interconnected conditions, dedicating spatial interconnect resources for all possible connections is costly and inefficient. Alternatively, we can time share physical network resources by virtualizing interconnect links, either by statically scheduling the sharing of resources prior to runtime or by dynamically negotiating resources at runtime. We explore the tradeoffs (e.g. area, route latency, route quality) between time-multiplexed and packet-switched networks overlayed on top of commodity FPGAs. We demonstrate modular and scalable networks which operate on a Xilinx XC2V6000-4 at 166MHz. For our applications, time-multiplexed, offline scheduling offers up to a 63% performance increase over online, packet-switched scheduling for equivalent topologies. When applying designs to equivalent area, packet-switching is up to 2times faster for small area designs while time-multiplexing is up to 5times faster for larger area designs. When limited to the capacity of a XC2V6000, if all communication is known, time-multiplexed routing outperforms packet-switching; however when the active set of links drops below 40% of the potential links, packet-switched routing can outperform time-multiplexing
Molecular and biochemical characterization of the human trk proto-oncogene. (1989)

Molecular analysis of the human trk oncogene, a transforming gene isolated from a colon carcinoma biopsy, revealed the existence of a novel member of the tyrosine kinase gene family. This locus, which we now designate the trk proto-oncogene, codes for a protein of 790 amino acid residues that has several features characteristic of cell surface receptors. They include (i) a 32-amino-acid-long putative signal peptide, (ii) an amino-terminal moiety (residues 33 to 407) rich in consensus sites for N-glycosylation, (iii) a transmembrane domain, (iv) a kinase catalytic region highly related to that of other tyrosine kinases, and (v) a very short (15 residue) carboxy-terminal tail. Residues 1 to 392 were absent in the trk oncogene, as they were replaced by tropomyosin sequences. However, no other differences were found between the transforming and nontransforming trk alleles (residues 392 to 790), suggesting that no additional mutations are required to activate the transforming potential of this gene. The human trk proto-oncogene codes for a 140,000-dalton glycoprotein, designated gp140proto-trk. However, its primary translational product is a 110,000-dalton glycoprotein which becomes immediately glycosylated, presumably during its translocation into the endoplasmic reticulum. This molecule, designated gp110proto-trk, is further glycosylated to yield the mature form, gp140proto-trk. Both gp110proto-trk and gp140proto-trk proteins possess in vitro kinase activity specific for tyrosine residues. Finally, iodination of intact NIH 3T3 cells expressing trk proto-oncogene products indicated that only the mature form, gp140proto-trk, cross the plasma membrane, becoming exposed to the outside of the cell. These results indicate that the product of the human trk locus is a novel tyrosine kinase cell surface receptor for an as yet unknown ligand.
Filterability and bank blood conservation media (1981)

A study was made of storage lesions of packed red cells stored in different preservative media: CPD, CPD-adenine, CPD-SAG, and CPD-pentoxifylline. The following chemical and physical parameters were studied: filterability, viscosity, ATP, 2-3,DPG pH, osmotic fragility, scanning electron microscopy pattern, blood gas levels. Tests were performed on days 0, 2, 4, 8, 16 and 24. The number and intensity of storage lesions in vitro give an indication of changes in oxygen-delivery capacity and flow characteristics of erythrocytes over a period of storage at 4 degrees C in different preservative media. CPD was found to maintain pertinent RBC properties up to Day 15. Adding adenine made little difference, whereas adding SAG gave better results. Pentoxifylline did not show appreciable effects in the initial concentrations used, which were close to those employed in medical practice. A preservative mixture ensuring maintenance of normal blood values during storage at 4 degrees C has yet to be found. Continued study of pentoxifylline should be conducted using higher concentrations of this additive.
Facile One Pot Microwave Induced Solvent-Free Synthesis and Antifungal, Antitubercular Screening of Spiro [1,5]-Benzothiazepin-2,3'[3'H]indol-2[1'H]-ones (2003)

Microwave activation coupled with dry media technique as a green chemistry procedure has been applied to synthesis of a series of some new title compounds. They have been obtained by the reaction of in situ synthesized 1,3-dihydro-3-[2-(phenyl/4-fluorophenyl)-2-oxoethylidene)-indol-2(1H)-one (4a, b) with substituted aminobenzenethiols (5a-d). The key intermediates 4a, b were also prepared in one step by this improved technique by reacting isatin and substituted acetophenones (2a, b). The results obtained under microwave irradiation when compared with that following conventional method demonstrate the versatility of the process. The title compounds 7a-e have also been screened for their antifungal and antitubercular activity, 7a and 7e showing maximum inhibition of growth of Alternaria alternata and Fusarium oxysporium and 7b, c, e revealing significant antitubercular activity.
Alkylthio Unit as an α-Pyrrole Protecting Group for Use in Dipyrromethane Synthesis (2006)

The synthesis of porphyrin precursors requires the successive introduction of substituents at the pyrrole alpha- and alpha'-positions (2- and 5-, respectively). An alpha-pyrrole substituent that serves as a temporary masking agent and is not deactivating would greatly facilitate such syntheses, particularly for beta-(3,4)-unsubstituted pyrroles, but has heretofore not been available. A series of alpha-RS groups (R = Me, Et, n-decyl, Ph) have been investigated in this regard, including the determination of the kinetics of substitution at the pyrrolic 3-, 4-, and 5-positions and the application to dipyrromethane formation. The RS group was readily introduced into the pyrrole alpha-position by the reaction of 2-thiocyanatopyrrole (prepared from pyrrole, ammonium thiocyanate, and iodine) and the corresponding Grignard reagent RMgBr. Each 2-alkylthio group activated the pyrrole ring toward deuteration at the 3- or 5- (vs 4-) position. The dipyrromethane synthesis was carried out using a 2:1 ratio of 2-(RS)pyrrole/benzaldehyde with a catalytic amount of InCl3 at room temperature in the absence of any solvent. The alpha-RS group was removed by hydrodesulfurization using Raney nickel or nickel complexes. This stoichiometric synthesis using the alpha-RS-protected pyrrole is in contrast to the traditional synthesis that employs an aldehyde and 25-100 mol equiv of pyrrole. Six meso-substituted dipyrromethanes were prepared by the reaction of 2-(n-decylthio)pyrrole/aldehyde/InCl3 (2.2:1:0.2 ratio) followed by hydrodesulfurization. Other reactions of the 1,9-bis(RS)dipyrromethane include oxidation to give (i) the 1,9-bis(RS)dipyrrin or (ii) the 1,9-bis(RSO2)dipyrromethane, which underwent subsequent complexation with dibutyltin dichloride. In summary, under mild reaction conditions, the 2-alkylthio group is readily introduced to the pyrrole nucleus, directs electrophilic substitution to the 5-position, and is readily removed as required for elaboration of porphyrinic precursors.
Recursively Scalable Fat-Trees as Interconnection Networks (2005)

We introduce orthogonal fat-trees as a type of interconnection network for parallel computers, and show how they can be used to maximize the number of processors in a massively parallel computer when the degree of the internal nodes and the diameter of the network are physically constrained. The basic building block of these orthogonal fat-trees is a two-level fat-tree that is obtained from a complete set of mutually orthogonal Latin Squares. As a practical application of orthogonal fat-trees, we propose a new interconnection network for a massively parallel computer based on the QROOOl Data Stream Controller Interface, an integrated circuit produced by National Semiconductor, which can sustain a throughput of up to 180 MBytes/sec. The network consists of multiple interconnected rings and is constrained to have at most 16 nodes per ring and a maximum diameter of four. Our solution yields a maximum of 51,984 processors.
Apicularens A and B, New Cytostatic Macrolides from Chondromyces Species (Myxobacteria): Production, Physico-chemical and Biological Properties. (1998)

A novel macrolide, apicularen A, was produced by several species of the genus Chondromyces. Initially it was discovered by bioassay-guided RP-HPLC-fractionation of culture extracts of Chondromyces robustus, strain Cm a13. Apicularen A showed no antimicrobial activity, but was highly cytotoxic for cultivated human and animal cells, with IC50 values ranging between 0.1 and 3 ng/ml. A cometabolite of apicularen A, the N-acetylglucosamine glycoside apicularen B, was distinctly less cytotoxic with IC50 values between 0.2 and 1.2 microg/ml, and showed weak activity against a few Gram-positive bacteria. Apicularen A is chemically closely related to the salicylihalamides A and B from the marine sponge Haliclona sp.
Electromyostimulation Training Effects on Neural Drive and Muscle Architecture (2005)

We concluded that the voluntary torque gains obtained after EMS training could be attributed to both muscular and neural adaptations. Both changes selectively involved the monoarticular vastii muscles.
Piezo-, pyro- and ferroelectrets: soft transducer materials for electromechanical energy conversion (2006)

Cellular space charge polymer electrets significantly enlarge the basis of pyro- and piezoelectric as well as ferroic materials. Since the first review of the field has been published in this journal (R. Gerhard-Multhaupt, Less can be more: Holes in polymers lead to a new paradigm of piezoelectric materials for electret transducers, IEEE Trans. Dielectr. Electr. Insul. Vol.9, pp.850-859, 2002), progress has been achieved in the understanding, preparation and characterization of cellular space charge electrets. Advanced applications arise in stacked microphones, artificial sonar systems, and in the combination of piezo- and ferroelectrets with flexible electronics. In the present survey an update of the developments since 2002 is provided
A systematic approach to the analysis of noise in mixers (1993)

A theory for the analysis of noise performance in active mixers is presented. An implementation of this theory using current simulation tools, as well as a more numerically efficient and accurate method, is included. The theory is used to analyze the noise figure of a 1-GHz monolithic mixer and agrees well with measured values.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Whooping cough due to Bordetella parapertussis: an unresolved problem (2004)

Bordetella parapertussis is one of the bacteria that causes whooping cough. However, little attention has been paid to this bacterium because it causes a milder illness than Bordetella pertussis and the rate of detection is low, even though research suggests that pertussis vaccines have limited efficacy against B. parapertussis infection. However, recent studies have revealed high rates of detection in patients with whooping cough in some field studies. In this review, the relevant studies of B. parapertussis are summarized and it is demonstrated that it is now necessary to pay greater attention to infections by this bacterium.
X11 Interaction with β-Amyloid Precursor Protein Modulates Its Cellular Stabilization and Reduces Amyloid β-Protein Secretion (1998)

The protein interaction domain of the neuronal protein X11 binds to the YENPTY motif within the cytoplasmic domain of beta-amyloid precursor protein (betaAPP). Amyloid-beta protein (Abeta), the major constituent of the amyloid deposited in brain of Alzheimer's disease patients, is generated by proteolytic processing of betaAPP, which occurs in part following betaAPP internalization. Because the YENPTY motif has a role in the internalization of betaAPP, the effect of X11 binding on betaAPP processing was studied in mouse neuroblastoma N2a, human embryonic kidney 293, monkey kidney COS-1, and human glial U251 cell lines transfected with wild type or mutated betaAPP cDNAs. Secretion of soluble betaAPP via alpha-secretase activity increased significantly in cells transfected with betaAPP variants containing mutations that impair interaction with X11 when compared with cells transfected with wild type cDNA. Cotransfection of betaAPP and X11 caused retention of cellular betaAPP, decreased secretion of sbetaAPPalpha, and decreased Abeta secretion. Thus, betaAPP interaction with the protein interaction domain of X11 stabilizes cellular betaAPP and thereby participates in the regulation of betaAPP processing pathways.
Temporally-independent functional modes of spontaneous brain activity (2012)

Resting-state functional magnetic resonance imaging has become a powerful tool for the study of functional networks in the brain. Even "at rest," the brain's different functional networks spontaneously fluctuate in their activity level; each network's spatial extent can therefore be mapped by finding temporal correlations between its different subregions. Current correlation-based approaches measure the average functional connectivity between regions, but this average is less meaningful for regions that are part of multiple networks; one ideally wants a network model that explicitly allows overlap, for example, allowing a region's activity pattern to reflect one network's activity some of the time, and another network's activity at other times. However, even those approaches that do allow overlap have often maximized mutual spatial independence, which may be suboptimal if distinct networks have significant overlap. In this work, we identify functionally distinct networks by virtue of their temporal independence, taking advantage of the additional temporal richness available via improvements in functional magnetic resonance imaging sampling rate. We identify multiple "temporal functional modes," including several that subdivide the default-mode network (and the regions anticorrelated with it) into several functionally distinct, spatially overlapping, networks, each with its own pattern of correlations and anticorrelations. These functionally distinct modes of spontaneous brain activity are, in general, quite different from resting-state networks previously reported, and may have greater biological interpretability.
