A Culinary Computational Creativity System (2014)

Compared to artifacts in expressive or performance domains, work products resulting from scientific creativity (including culinary recipes) seem much more conducive to data-driven assessment. If such products are viewed as an assembly of constituents that follow certain association principles, one could apply computationally intensive techniques to generate many possible combinations and use automated assessors to evaluate each of them. Assembly work plans for the selected novel products could subsequently be inferred from existing records. In this chapter, we report on our efforts to build a computational creativity system for culinary recipes. After gathering data and creating a knowledge base of recipes and ingredients, the system generates ingredient combinations that satisfy user inputs such as the choice of key ingredient, desired dish, and cuisine. Once a combination has been selected with the help of novelty and quality evaluators, the system further recommends ingredient proportions using a distributional conformance method and generates recipe steps using a subgraph composition algorithm. The time durations or efforts of atomic steps are estimated by solving an inverse problem from data on complete recipes. The example of culinary recipes could be generalized and applied to other scientific domains; manufacturing products and business processes could potentially follow a similar recipe for success.
Reactions of K2PtCl4 with pyridine derivatives in dimethylformamide and synthesis of potassium trichloro(pyridine)platinum(II) (1978)

The reactions of K 2 PtCl 4 with pyridine derivatives L (L = py = pyridine, pic = picoline, and lut = lutidine) were studied in dimethylformamide (DMF).[Formula: see text]The complexes (1) were isolated and the yield decreased with the order, 2,4-lut = 2-pic &gt; 2,6-lut &gt; 4-pic = py, which can be correlated to the steric hindrance of the ortho methyl groups. The compounds (2) can be converted to the compounds (3), the free ligand acting as catalyst and (3) is the final product of the above reactions. The compounds (3) can also be obtained from a DMF solution of [Pt(L) 4 ]Cl 2 (L = py) at room temperature. A comparison of the above reactions in water and in DMF was also made.
Apolipoprotein E-Deficient Mice Have Increased Susceptibility To Focal Cerebral Ischemia (1997)

Recent evidence suggests that apolipoprotein E (ApoE) plays a role in neurologic disease. This experiment compared the neurologic and histologic outcome of ApoE-deficient mutant and wild-type mice subjected to a 60- or 90-minute episode of middle cerebral artery filament occlusion and a recovery interval of 24 hours. With 60 minutes of ischemia, there was no mortality. Apolipoprotein E-deficient mice had larger infarcts (cortex: ApoE deficient = 20 mm3 +/- 12, wild-type = 9 +/- 7 mm3, P = 0.03; subcortex: ApoE deficient = 22 +/- 7 mm3, wild-type = 16 +/- 7 mm3, P = 0.07). Hemiparesis was less severe in wild-type animals (P = 0.02). After 90 minutes of ischemia, mortality in ApoE-deficient mice (n = 10) was 40% versus 0% in wild-type mice (n = 10; P = 0.09). Intraparenchymal hemorrhage was found in 3 of the 4 dead mice. No difference in cortical (ApoE deficient = 37 +/- 8 mm3; wild-type = 31 +/- 18 mm3; P = 0.49) or subcortical (ApoE deficient = 30 +/- 11 mm3; wild-type = 32 +/- 18 mm3; P = 0.78) infarct volumes was present among survivors. ApoE-deficient mice had a prolonged activated partial thromboplastin time and increased fibrinogen concentration. This data supports the hypothesis that apolipoprotein E plays a role in the pathophysiology of ischemic brain damage.
Synchronized Firing in Coupled Inhomogeneous Excitable Neurons (2002)

We study the firing synchronization behavior of the inhomogeneous excitable media. Phase synchronizationof neuron firings is observed with increasing the coupling, while the phases of neurons are different (out-of-phase synchronization). We found the synchronization of bursts can be greatly enhanced by applying an external forcing (in-phasesynchronization). The external forcing can be either a periodic or just homogeneous thermal noise. The mechanismresponsible for this enhancement is discussed.PACS numbers: 05.45.-a, 87.10.+e
The relationship between osteoclastogenic and anti-osteoclastogenic pro-inflammatory cytokines differs in human osteoporotic and osteoarthritic bone tissues (2012)

Our results demonstrate that the relationship between osteoclastogenic and anti-osteoclastogenic pro-inflammatory cytokines differs in human OP and OA bone and could present an important factor for characteristics of OP and OA bone phenotypes.
Chimeric plant calcium/calmodulin-dependent protein kinase gene with a neural visinin-like calcium-binding domain. (1995)

Calcium, a universal second messenger, regulates diverse cellular processes in eukaryotes. Ca2+ and Ca2+/calmodulin-regulated protein phosphorylation play a pivotal role in amplifying and diversifying the action of Ca(2+)-binding domain was cloned and characterized from lily. The cDNA clone contains an open reading frame coding for a protein of 520 amino acids. The predicted structure of CCaMK contains a catalytic domain followed by two regulatory domains, a calmodulin-binding domain and a visinin-like Ca(2+)-binding domain. The amino-terminal region of CCaMK contains all 11 conserved subdomains characteristic of serine/threonine protein kinases. The calmodulin-binding region of CCaMK has high homology (79%) to alpha subunit of mammalian Ca2+/calmodulin-dependent protein kinase. The calmodulin-binding region is fused to a neural visinin-like domain that contains three Ca(2+)-binding EF-hand motifs and a biotin-binding site. The Escherichia coli-expressed protein (approximately 56 kDa) binds calmodulin in a Ca(2+)-dependent manner. Furthermore, 45Ca-binding assays revealed that CCaMK directly binds Ca2+. The CCaMK gene is preferentially expressed in developing anthers. Southern blot analysis revealed that CCaMK is encoded by a single gene. The structural features of the gene suggest that it has multiple regulatory controls and could play a unique role in Ca2+ signaling in plants.
Hydroxyapatite-Coated Femoral Stem Survivorship at 10 Years (2005)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Controlled Sedation with Alphaxalone-Alphadolone (1974)

Alphaxalone-alphadolone (Althesin), diluted and administered as a controlled infusion, was used as a sedative for 30 patients in an intensive therapy unit. This technique allowed rapid and accurate control of the level of sedation. It had three particularly useful applications: it provided "light sleep," allowed rapid variation in the level of sedation, and enabled repeated assessment of the central nervous system.Sedation was satisfactory for 86% of the total time, and no serious complications were attributed to the use of the drug. Furthermore, though alphaxalone-alphadolone was given for periods up to 20 days there was no evidence of tachyphylaxis or delay in recovery time.
Covalent association of the traI gene product of plasmid RP4 with the 5'-terminal nucleotide at the relaxation nick site. (1990)

Formation of relaxosomes is the first step in the initiation of transfer DNA replication during bacterial conjugation. This nucleoprotein complex contains all components capable of introducing a site- and strand-specific nick at a cognate transfer origin (oriT) on supercoiled plasmid DNA, thus providing the substrate for generation of the strand to be transferred. Characterization of the terminal nucleotides at the oriT nick site revealed that relaxation occurs by hydrolysis of a single phosphodiester bond between a 2'-deoxyguanosyl and a 2'-deoxycytidyl residue. The relaxation nick site and a 19-base pair invert repeat sequence that is recognized by asymmetric binding of the RP4 TraJ protein are interspaced by 8 base pairs. The nicking reaction results in covalent attachment of the RP4 TraI protein to the 5'-terminal 2'-deoxycytidyl residue of the cleaved strand. The arrangement of the TraJ binding site and the relaxation nick site on the same side of the DNA double helix suggests that protein-protein interactions between TraJ and TraI are a prerequisite for oriT specific nicking. In accordance with the current model of transfer DNA replication, the 3' end remains accessible for primer extension by DNA polymerase I, enabling replacement strand synthesis in the donor cell by a rolling circle-type mechanism.
Exosomal microRNA signatures in multiple sclerosis reflect disease status (2017)

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS). There is currently no single definitive test for MS. Circulating exosomes represent promising candidate biomarkers for a host of human diseases. Exosomes contain RNA, DNA, and proteins, can cross the blood-brain barrier, and are secreted from almost all cell types including cells of the CNS. We hypothesized that serum exosomal miRNAs could present a useful blood-based assay for MS disease detection and monitoring. Exosome-associated microRNAs in serum samples from MS patients (n = 25) and matched healthy controls (n = 11) were profiled using small RNA next generation sequencing. We identified differentially expressed exosomal miRNAs in both relapsing-remitting MS (RRMS) (miR-15b-5p, miR-451a, miR-30b-5p, miR-342-3p) and progressive MS patient sera (miR-127-3p, miR-370-3p, miR-409-3p, miR-432-5p) in relation to controls. Critically, we identified a group of nine miRNAs (miR-15b-5p, miR-23a-3p, miR-223-3p, miR-374a-5p, miR-30b-5p, miR-433-3p, miR-485-3p, miR-342-3p, miR-432-5p) that distinguished relapsing-remitting from progressive disease. Eight out of nine miRNAs were validated in an independent group (n = 11) of progressive MS cases. This is the first demonstration that microRNAs associated with circulating exosomes are informative biomarkers not only for the diagnosis of MS, but in predicting disease subtype with a high degree of accuracy.
Human placental apurinic/apyrimidinic endonuclease. Its isolation and characterization. (1982)

An endonuclease from human placenta has been purified to apparent homogeneity, which acts specifically on DNA containing either apurinic or apyrimidinic sites. The isolation procedure, which results in a 20,000-fold purification and an overall yield of 15%, employs chromatography on a gel of octyl succinic anhydride coupled to agarose by diaminohexane spacers, isoelectric focusing, Sephadex G-75 chromatography, and DNA agarose affinity chromatography. Under conditions in which proteolysis is minimized, this enzyme appears to be the major species of apurinic/apyrimidinic endonuclease. The endonuclease is a monomeric protein with an apparent Mr = 37,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The enzyme has a pI of 7.4-7.6, requires Mg2+, is partially stimulated by Mn2+, and is inhibited by EDTA. It has no detectable exonuclease or phosphomonoesterase activity.
UV/Vis Spectra of Subporphyrazines and Subphthalocyanines with Aluminum and Gallium: A Time‐Dependent DFT Study (2013)

The UV/Vis spectra of selected substituted subporphyrazines (SubPz) and subphthalocyanines (SubPc) with aluminum and gallium as central atoms are analyzed through time-dependent DFT calculations in chloroform. The results are compared with previous results with boron as the central atom to analyze the photochemical properties of these two families of compounds on varying the metal along the same group. The absorptions of SubPz (Al, Ga) are redshifted or blueshifted with respect to SubPz (B) depending on the nature of the R substituents of the molecule, whereas the absorptions of SubPc (Al, Ga) structures are redshifted and with smaller energy gaps with respect to SubPc (B) for all kinds of R substituents. Looking at their absorption spectra, these systems with aluminum and gallium may also have, as in the case of boron, promising photochemical properties.
Detection and measurement of PCR bias in quantitative methylation analysis of bisulphite-treated DNA (1997)

Methylation analysis of individual cytosines in genomic DNA can be determined quantitatively by bisulphite treatment and PCR amplification of the target DNA sequence, followed by restriction enzyme digestion or sequencing. Methylated and unmethylated molecules, however, have different sequences after bisulphite conversion. For some sequences this can result in bias during the PCR amplification leading to an inaccurate estimate of methylation. PCR bias is sequence dependent and often strand-specific. This study presents a simple method for detection and measurement of PCR bias for any set of primers, and investigates parameters for overcoming PCR bias.
arc-dependent thermal regulation and extragenic suppression of the Escherichia coli cytochrome d operon (1992)

In a screen for Escherichia coli genes whose products are required for high-temperature growth, we identified and characterized a mini-Tn10 insertion that allows the formation of wild-type-size colonies at 30 degrees C but results in microcolony formation at 36 degrees C and above (Ts- phenotype). Mapping, molecular cloning, and DNA sequencing analyses showed that the mini-Tn10 insertion resides in the cydB gene, the distal gene of the cydAB operon (cytochrome d). The Ts- growth phenotype was also shown to be associated with previously described cyd alleles. In addition, all cyd mutants were found to be extremely sensitive to hydrogen peroxide. Northern (RNA) blot analysis showed that cyd-specific mRNA levels accumulate following a shift to high temperature. Interestingly, this heat shock induction of the cyd operon was not affected in an rpoH delta background but was totally absent in an arcA or arcB mutant background. Extragenic suppressors of the Cyd Ts- phenotype are found at approximately 10(-3). Two extragenic suppressors were shown to be null alleles in either arcA or arcB. One interpretation of our results is that in the absence of ArcA or ArcB, which are required for the repression of the cyo operon (cytochrome o), elevated levels of Cyo are produced, thus compensating for the missing cytochrome d function. Consistent with this interpretation, the presence of the cyo gene on a multicopy plasmid suppressed the Ts- and hydrogen peroxide-sensitive phenotypes of cyd mutants.
Mechanistic Investigation on the Formation of Indolizines from 2-Enynylpyridines (2009)

2,3,7-Trisubstituted indolizines were obtained from E- or Z-2-enynyl-4-substituted pyridines. The mechanistic pathway involves a base-catalyzed double-bond isomerization, if the E-isomer is the starting material, followed by a concerted pseudocoarctate cyclization.
Wild type p53 can mediate sequence-specific transactivation of an internal promoter within the mdm2 gene. (1993)

The p53 tumor suppressor gene product can complex with polypeptides encoded by the mdm2 putative protoncogene. In addition, mdm2 mRNA levels have been shown to increase following the activation of wild type (wt) p53. To determine the basis for the effect of wt p53 on mdm2 mRNA, we studied the interaction of the mdm2 gene with p53. We report that wt p53 can bind sequence-specifically to a DNA region residing downstream to exon 1 of the mdm2 gene. This is correlated with a pronounced p53-dependent transcriptional activation. Efficient p53-dependent transactivation can be obtained with an mdm2 genomic DNA fragment lacking the putative mdm2 promoter. These findings suggest that p53 can induce transcription from an internal promoter located within the mdm2 gene. These findings raise the possibility that, in addition to increasing the overall levels of mdm2 mRNA, wt p53 may also modulate the repertoire of mdm2 transcripts present within the cell.
Multichannel ambulatory monitoring of circulation related biosignals (2002)

The Micro-Monitor is a miniaturized data processing system, which was developed for the requirements in the field of ambulatory patient-monitoring. The Micro-Monitor is based on a 8-bit single-chip-microcomputer with RAM, ROM, input/output-ports, timer, and integrated analog-digital conversion (ADC). The system contains a 128 kbyte CMOS-SRAM, a real-time-clock, and an electrocardiogram-amplifier. Via 7 miniature connectors, various transducers can be connected for the combined monitoring of different physiological signals. A nearly unlimited number of operation modes can be defined by software. The 250 mAh rechargeable battery packet powers the microcomputer with its transducers and amplifiers for several days.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Human N-Myristoyltransferase Amino-terminal Domain Involved in Targeting the Enzyme to the Ribosomal Subcellular Fraction (1997)

N-Myristoyltransferase (NMT) catalyzes the cotranslational acylation with myristic acid of the NH2-terminal glycines of a number of cellular and viral proteins. Most of the in vitro NMT activity (60-85%) in isoosmotic cell homogenates of human lymphoblastic leukemia (i.e. CEM and MOLT-4) and cervical carcinoma (i.e. HeLa) cells was shown to be associated with the ribosomal subcellular fractions by differential centrifugation. Also found in the ribosomal fractions was a approximately 60-kDa protein that was specifically immunoblotted with an anti-human NMT (hNMT) peptide antibody. This approximately 60-kDa protein was stable in the presence of proteolytic enzyme inhibitors but was gradually converted into a approximately 46-kDa species when stored in the absence of protease inhibitors. Sucrose density gradient centrifugation of the ribosomal fraction resulted in the hNMT activity sedimenting exactly coincident with the 260 nm absorption profile and exhibiting A260/A280 absorption ratios >1.8, indicating an association of NMT with putative ribosomal particle(s)/subunit(s). The subcellular targeting of hNMT was also examined by immunoblotting subcellular fractions from HeLa cells transfected with plasmids containing FLAG epitope-tagged hNMT inserts corresponding either to the originally assigned hNMT gene or to an alternative open reading frame initiated from an in-frame start site upstream from the assumed hNMT start site. Anti-FLAG immunoblotting of cells transfected with a plasmid containing the larger insert revealed FLAG-NMT primarily in the ribosomal fraction with an apparent molecular mass similar to the approximately 60-kDa native hNMT. In contrast, immunoblotting of cells transfected with a plasmid containing the smaller insert identified a approximately 50-kDa FLAG-NMT predominantly in the cytosolic fraction. An analysis of mixtures of CEM ribosomes and serial dilutions of purified recombinant FLAG-NMTs demonstrated that the approximately 60-kDa FLAG-NMT binds ribosomes with higher affinity than the approximately 50-kDa FLAG-NMT. These in vivo and in vitro subcellular targeting and recombinant expression experiments identify a native hNMT that is 10-12 kDa larger than the enzyme predicted by the originally assigned hNMT gene and which is apparently translated from an alternative up-stream start site. The data also indicate that although the unique NH2-terminal residues encoded by this larger open reading frame are not required for in vitro catalytic activity, they do provide signal(s) involved in targeting hNMT to the ribosomal subcellular fraction where cotranslational N-myristoylation occurs.
Binaural cue coding-part I: psychoacoustic fundamentals and design principles (2003)

Binaural Cue Coding (BCC) is a method for multichannel spatial rendering based on one down-mixed audio channel and BCC side information. The BCC side information has a low data rate and it is derived from the multichannel encoder input signal. A natural application of BCC is multichannel audio data rate reduction since only a single down-mixed audio channel needs to be transmitted. An alternative BCC scheme for efficient joint transmission of independent source signals supports flexible spatial rendering at the decoder. This paper (Part I) discusses the most relevant binaural perception phenomena exploited by BCC. Based on that, it presents a psychoacoustically motivated approach for designing a BCC analyzer and synthesizer. This leads to a reference implementation for analysis and synthesis of stereophonic audio signals based on a Cochlear Filter Bank. BCC synthesizer implementations based on the FFT are presented as low-complexity alternatives. A subjective audio quality assessment of these implementations shows the robust performance of BCC for critical speech and audio material. Moreover, the results suggest that the performance given by the reference synthesizer is not significantly compromised when using a low-complexity FFT-based synthesizer. The companion paper (Part II) generalizes BCC analysis and synthesis for multichannel audio and proposes complete BCC schemes including quantization and coding. Part II also describes an alternative BCC scheme with flexible rendering capability at the decoder and proposes several applications for both BCC schemes.
Adaptive-Compi: Enhancing Mpi-Based Applications’ Performance and Scalability by using Adaptive Compression (2010)

This paper presents an optimization of MPI communication, called Adaptive-CoMPI, based on runtime compression of MPI messages exchanged by applications. The technique developed can be used for any application, because its implementation is transparent for the user, and integrates different compression algorithms for both MPI collective and point-to-point primitives. Furthermore, compression is turned on and off and the most appropriate compression algorithms are selected at runtime, depending on the characteristics of each message, the network behavior, and compression algorithm behavior, following a runtime adaptive strategy. Our system can be optimized for a specific application, through a guided strategy, to reduce the runtime strategy overhead. Adaptive-CoMPI has been validated using several MPI benchmarks and real HPC applications. Results show that, in most cases, by using adaptive compression, communication time is reduced, enhancing application performance and scalability.
Lapatinib Combined With Letrozole Versus Letrozole and Placebo As First-Line Therapy for Postmenopausal Hormone Receptor–Positive Metastatic Breast Cancer (2009)

This trial demonstrated that a combined targeted strategy with letrozole and lapatinib significantly enhances PFS and clinical benefit rates in patients with MBC that coexpresses HR and HER2.
Epidemiology and Natural History of Nonalcoholic Fatty Liver Disease (2015)

The epidemic of obesity has resulted in a parallel incremental burden of nonalcoholic fatty liver disease (NAFLD) worldwide. Nonalcoholic fatty liver disease includes a spectrum of liver disease that ranges from simple fat accumulation in the liver to necroinflammation, fibrosis, cirrhosis, and hepatocellular carcinoma, which in essence represent the stages of the natural history of NAFLD. The rising prevalence of NAFLD globally may be accounted for by changes in dietary habits and an increase in sedentary lifestyle. Nonalcoholic steatohepatitis (NASH), the aggressive form of NAFLD, is currently the second leading etiology of liver disease among adults awaiting liver transplantation in the United States. In the current review, the authors discuss the uncertainty around the progression from NAFL (steatosis) to NASH (steatohepatitis), the undisputed progression of NASH to cirrhosis, and the risk factors that predispose to such progression. The published literature on the long-term cardiovascular complications and liver-related mortality of NAFLD is also discussed.
