Presidential Address: English Landed Society in the Twentieth Century: II, New Poor and New Rich. (1991)

The notion that the great leviathans of wealth, who had for so long been accustomed to taking first place in a nation of snobs which contrived simultaneously to accept, admire, envy, and criticise their opulence, might actually become impoverished first began to gain some currency in the 1890s. True, this had been anticipated by a few specially pessimistic and debt–ridden landowners in the immediate anxieties aroused by the Repeal of the Corn Laws. Lord Monson, who had inherited from a cousin estates liberally furnished with dowagers and other inescapable expenses, and who was in despair at the tendency of income to fall while outgoings remained fixed, exploded to his son in 1851: ‘What an infernal bore is landed property. No certain income can be reckoned upon. I hope your future wife will have Consols or some such ballast, I think it is worth half as much again as land’. A similar but more sober banker's view had been put by Evelyn Denison, a classic gentlemanly capitalist, in 1847 when he announced his intention to sell much of his land ‘not because I am of the class of encumbered landlords, for I have luckily extricated myself from that, but because I do not think it worth while to keep a security paying 2 per cent, when I can get an equally good one paying ’.
The Role of NUP98 Gene Fusions in Hematologic Malignancy (2004)

Chromosomal aberrations occur with great frequency and some specificity in leukemia and other hematologic malignancies. The most common outcome of these rearrangements is the formation of a fusion gene, comprising portions of 2 genes normally present in the cell. These fusion proteins are presumed to be oncogenic; in many cases, animal models have proven them to be oncogenic. One of the most promiscuous fusion partner genes is the newly identified NUP98 gene, located on chromosome 11p15.5, which to date has been observed fused to 15 different fusion partners. NUP98 encodes a 98 kD protein that is an important component of the nuclear pore complex, which mediates nucleo-cytoplasmic transport of protein and RNA. The fusion partners of NUP98 form 2 distinct groups: homeobox genes and non-homeobox genes. All NUP98 fusions join the N-terminal GLFG repeats of NUP98 to the C-terminal portion of the partner gene, which, in the case of the homeobox gene partners, includes the homeodomain. Clinical findings are reviewed here, along with the findings of several in vivo and in vitro models have been employed to investigate the mechanisms by which NUP98 fusion genes contribute to the pathogenesis of leukemia.
Association Between Telomere Length, Specific Causes of Death, and Years of Healthy Life in Health, Aging, and Body Composition, a Population-Based Cohort Study (2009)

Although telomere length (TL) is known to play a critical role in cellular senescence, the relationship of TL to aging and longevity in humans is not well understood. In a large biracial population-based cohort, we tested the hypotheses that elderly persons with shorter TL in peripheral white blood cells have poorer survival, shorter life span, and fewer years of healthy life (YHL). Associations were evaluated using Cox proportional hazard models and linear regression analyses where appropriate. TL (in kilo base pairs) was not associated with overall survival (hazard ratio 1.0; 95% confidence interval 0.9-1.1) or death from any specific underlying cause including infectious diseases, cancer, or cardiac and cerebrovascular diseases. TL, however, was positively associated with more YHL (beta = 0.08 +/- 0.04, p = .03). Findings suggest that TL may not be a strong biomarker of survival in older individuals, but it may be an informative biomarker of healthy aging.
Using the Rotaxane Mechanical Bond to Enhance Chemical Reactivity (2010)

Rates of cycloreversion for squaraine rotaxane mono(endoperoxides) were enhanced by structural modifications that increased cross-component steric destabilization of the inward directed 9,10-anthracene endoperoxide group. The largest rate enhancements were obtained when the surrounding macrocycle contained two 2,6-pyridine dicarboxamide bridging units, which induced a cavity contraction effect. The precursor fluorescent, near-IR, squaraine rotaxanes are effectively photostable because the mono(endoperoxide) products, formed by reaction with photogenerated singlet oxygen, rapidly cyclorevert back to the original squaraine rotaxane.
Earnings Management through Affiliated Transactions (2004)

Prior research has investigated earnings management primarily through the use of discretionary accruals. We examine whether, in addition to discretionary accruals, firms further engage in earnings management using transactions with affiliated companies. When a parent company has a dominant relation over affiliated companies, the parent company can structure transactions between itself and affiliates in a way that allows it to achieve income-reporting objectives beyond the use of discretionary accruals. We address this research issue in Japan because Japanese firms issue both parent and consolidated financial statements. In addition to earnings management techniques that can be used to manage consolidated earnings, parent earnings can also be managed using transactions with affiliates. We find earnings management behavior for both parent and consolidated earnings around three earnings thresholds: avoiding losses, avoiding earnings declines, and avoiding negative forecast errors. Consistent with additional earnings management through affiliated transactions, parent earnings show stronger evidence of earnings management than consolidated earnings at each of these three earnings thresholds. Further tests indicate that the increased management of parent earnings around these three earnings thresholds is related to the firm's ability to use affiliated transactions, while the management of consolidated earnings is unrelated to the firm's ability to use affiliated transactions.
Procoagulant activity in glomeruli and urine of rabbits with nephrotoxic nephritis. (1985)

A telescoped model of nephrotoxic nephritis in the rabbit, using guinea pig antiglomerular basement membrane IgG in rabbits preimmunized with guinea pig IgG, reproducibly induced crescentic nephritis. Procoagulant activity (PCA) was measured in sieve-isolated glomeruli that had been either sonicated or cultured for 48 hours. In both sonicated and cultured glomeruli PCA peaked on days 5 and 6. The time course for appearance of PCA corresponded precisely with the appearance of proteinaceous material containing fibrin in Bowman's space as measured by a light microscopic histologic scoring system and confirmed by immunofluorescence and electron microscopy. Glomerular PCA returned to baseline by days 9 and 10 in spite of progression of glomerular injury. PCA also appeared in urine. Urine PCA peaked on day 8 and persisted through day 12 when glomerular PCA had returned to baseline. Glomerular and urine PCA were characterized using human coagulation factor-deficient plasmas and antithromboplastin IgG. Both glomerular PCA and urine PCA were inhibited by antithromboplastin IgG, showing that thromboplastin (tissue factor) contributed to PCA. The PCA in glomerular sonicates was dependent on factor X, but independent of factor VII or Hageman factor, suggesting that factor VII was present. Following glomerular culture for 48 hours the PCA had changed and in some cases was dependent on Hageman factor, factor IX, and factor VII for full PCA expression. Urine PCA was uniformly Hageman factor dependent and sometimes independent of factors VII and X. No active thrombin was present. The forms of glomerular and urine PCA were, therefore, complex. They seemed to be primarily driven by thromboplastin but also appeared to require the presence of the intrinsic coagulation pathway for full expression of PCA.
Functional studies of E7 proteins from different HPV types. (1994)

We have performed comparative studies on the E7 proteins from malignant and non-malignant Human Papillomavirus types HPV 1, 6, 11, 16, 18, 33). GST/E7 fusion proteins from all these HPV types associate with Rb1, p107 and the cyclin A/CDK2 complex. As has been shown for Rb1, the association with p107 and Cyclin A was weaker for the 'low risk' HPV6 and 11 E7 proteins as compared to 'high risk' HPV16, 18 and 33 E7 proteins. In contrast the E7 protein of the benign type HPV1 bound Rb1, p107 and cyclin A with the same affinity as the 'high risk' E7 proteins. The affinities of the E7/Rb1 interaction have been confirmed in vivo by the 'two hybrid' method in the yeast Saccharomyces cerevisiae. Although HPV1 E7 showed the same affinity in vitro and in vivo for Rb1 as the high risk HPV E7s, it did not have the ability to activate the E2F-1 transcription factor inhibited by Rb1, nor did it have any transforming activity when coexpressed with activated ras in primary rodent cells.
Synthesis of 2-Alkyl-3-hydroxy-4-pyridinone-ribonucleosides, Potential Oral Iron Chelators (1995)

Abstract Several ribonucleosides, named 2-alkyl-3-hydroxy-1-(β-D-ribofuranosyl or pyranosyl)-4-pyridinones, were synthesized in good yield. The method provides a useful means to obtain α-ketohydroxypyridin derivatives with different sugar moieties that, if used as drugs, might enhance their absorption from the intestine and certain other desirable pharmacological properties.
A retrospective on the Dorado, a high-performance personal computer (1983)

In late 1975, members of the Xerox Palo Alto Research Center embarked on the specification of a high•performance successor to the Alto personal minicomputer, in use since 1973.After four years, the resulting machine, called the Dorado, was in use within the research community at PARCo This paper begins with an overview of the design goals, architecture, and implementation of the Dorado and then provides a retrospective view and critique of the Dorado project as a whole.The major machine architectural features are evaluated, other project aspects such as design automation and management structures are explained, a chronological history with milestones is included, and a variety of accomplish• ments, red herrings, and shortfalls is discussed.The paper concludes with some speculations on what the project might have done differently and what might be done differently today instead of in the late 1970s.Although more than a dozen scientists and technicians contributed to the project, the evaluative and speculative parts of this paper are the sole responsibility of the author.
The somatostatin analogue SMS 201-995 in long-term treatment of vipoma. Case report. (1989)

In a 60-year-old woman with an inoperable vipoma, satisfactory improvement of severe watery diarrhea was obtained over a 12-month period by subcutaneous administration of the somatostatin analogue SMS 201-995. It is suggested that SMS 201-995 may be useful in such inoperable cases, or when surgery would carry a high risk.
Decreased cGMP Level Contributes to Increased Contraction in Arteries From Hypertensive Rats (2011)

Recent evidence suggests that angiotensin II (Ang II) upregulates phosphodiesterase (PDE) 1A expression. We hypothesized that Ang II augmented PDE1 activation, decreasing the bioavailability of cyclic guanosine 3' 5'-monophosphate (cGMP), and contributing to increased vascular contractility. Male Sprague-Dawley rats received mini-osmotic pumps with Ang II (60 ng·min(-1)) or saline for 14 days. Phenylephrine (PE)-induced contractions were increased in aorta (E(max)168% ± 8% vs 136% ± 4%) and small mesenteric arteries (SMA; E(max)170% ± 6% vs 143% ± 3%) from Ang II-infused rats compared to control. PDE1 inhibition with vinpocetine (10 μmol/L) reduced PE-induced contraction in aortas from Ang II rats (E(max)94% ± 12%) but not in controls (154% ± 7%). Vinpocetine decreased the sensitivity to PE in SMA from Ang II rats compared to vehicle (-log of half maximal effective concentration 5.1 ± 0.1 vs 5.9 ± 0.06), but not in controls (6.0 ± 0.03 vs 6.1 ± 0.04). Sildenafil (10 μmol/L), a PDE5 inhibitor, reduced PE-induced maximal contraction similarly in Ang II and control rats. Arteries were contracted with PE (1 μmol/L), and concentration-dependent relaxation to vinpocetine and sildenafil was evaluated. Aortas from Ang II rats displayed increased relaxation to vinpocetine compared to control (E(max)82% ± 12% vs 445 ± 5%). SMA from Ang II rats showed greater sensitivity during vinpocetine-induced relaxation compared to control (-log of half maximal effective concentration 6.1 ± 0.3 vs 5.3 ± 0.1). No differences in sildenafil-induced relaxation were observed. PDE1A and PDE1C expressions in aorta and PDE1A expression in SMA were increased in Ang II rats. cGMP production, which is decreased in arteries from Ang II rats, was restored after PDE1 blockade. We conclude that PDE1 activation reduces cGMP bioavailability in arteries from Ang II, contributing to increased contractile responsiveness.

Technological and economic potential of poly(lactic acid) and lactic acid derivatives (1995)

Lactic acid has been an intermediate-volume specialty chemical (world production ∼ 40,000 tons/yr) used in a wide range of food processing and industrial applications. Lactic acid has the potential of becoming a very large volume, commodity-chemical intermediate produced from renewable carbohydrates for use as feedstocks for biodegradable polymers, oxygenated chemicals, plant growth regulators, environmentally friendly ‘green’ solvents, and specialty chemical intermediates. The recent announcements of new development-scale plants for producing lactic acid and polymer intermediates by major U.S. companies, such as Cargill, Ecochem (DuPont/ConAgra), and Archer Daniels Midland, attest to this potential. In the past, efficient and economical technologies for the recovery and purification of lactic acid from crude fermentation broths and the conversion of lactic acid to the chemical or polymer intermediates had been the key technology impediments and main process cost centers. The development and deployment of novel separations technologies, such as electrodialysis (ED) with bipolar membranes, extractive distillations integrated with fermentation, and chemical conversion, can enable low-cost production with continuous processes in large-scale operations. The use of bipolar ED can virtually eliminate the salt or gypsum waste produced in the current lactic acid processes. Thus, the emerging technologies can use environmentally sound processes to produce environmentally useful products from lactic acid. The process economics of some of these processes and products can also be quite attractive. In this paper, the recent technical advances in lactic and polylactic acid processes are discussed. The economic potential and manufacturing cost estimates of several products and process options are presented. The technical accomplishments at Argonne National Laboratory (ANL) and the future directions of this program at ANL are discussed.
Network Anomaly Detection Using One Class Support Vector Machine (2008)

Abstract—Anomaly detection is automatic identification of the abnormal behaviors embedded in a large amount of normal data. This paper presents a method based on one class support vector machine (OCSVM) for detecting network anomalies. The telecommunication network performance data are used for the investigation. Firstly, the raw data are preprocessed in order to produce the vector sets required by the OCSVM algorithm. After preprocessing, the vector set of the training data is used to train the OCSVM detector, which is capable of learning the nominal behaviors of the data. The trained detector is then applied on the test data to detect the anomalies. The detected anomalies are finally categorized into major or minor level by comparing with a threshold. In this paper, experiments on three different types of performance data are presented and the results demonstrate the promising performance of the algorithm. Index Terms—Anomaly detection, one class support vector machine, telecommunication, time series. I.
Genetically Altered Mice with Different Sialyltransferase Deficiencies Show Tissue-specific Alterations in Sialylation and Sialic Acid 9-O-Acetylation (2002)

Glycan chains on glycoconjugates traversing the Golgi apparatus are often terminated by sialic acid residues, which can also be 9-O-acetylated. This process involves competition between multiple Golgi enzymes. Expression levels of Golgi enzyme mRNAs do not always correlate with enzyme activity, which in turn cannot accurately predict glycan sequences found on cell surfaces. Here we examine the cell type-specific expression of terminal glycans in tissues of normal mice in comparison with animals deficient in ST6Gal-I (transfers alpha2-6-linked sialic acid to Galbeta1-4GlcNAc) or ST3Gal-I (transfers alpha2-3-linked sialic acid to Galbeta1-3GalNAc). Tissues of ST6Gal-I null mice showed minimal binding of an alpha2-6-sialic acid-specific lectin, indicating that no other enzyme generates Siaalpha2-6Galbeta1-4GlcNAc and that Siaalpha2-6GalNAc (sialyl-Tn) is rare in mice. However, exposed Galbeta1-4GlcNAc termini were only moderately increased, indicating that these can be partially capped by other enzymes. Indeed, Galalpha1-3Galbeta1-4GlcNAc and Fucalpha1-2Galbeta1-4GlcNAc termini were enhanced in some tissues. Many tissues of ST3Gal-I null animals showed increases in Galbeta1-3GalNAc termini, and some increases in poly-N-acetyllactosamines. However, overall expression of alpha2-3-linked sialic acid was selectively reduced only in a few instances, indicating that other ST3Gal enzymes can generate this linkage in most tissues. Highly selective losses of 9-O-acetylation of sialic acid residues were also observed, with ST6Gal-I deficiency causing loss on endothelium and ST3Gal-I deficiency giving a marked decrease on CD4(+) lymphocytes. These data demonstrate selective regulation of sialylation and 9-O-acetylation, point to cell types with potential physiological defects in null animals, and show in vivo evidence for competition between Golgi enzymes.
Association between HLA-DRB1*15 and secondary Sjögren's syndrome in patients with rheumatoid arthritis. (2000)

Secondary SS is associated with an increased frequency of HLA-DRB1*15 in seropositive patients with RA from northwestern Spain. HLA-DRB1*15 is also associated with RA in SE negative individuals without secondary SS, although the possibility that such patients will later develop SS cannot be ruled out. Further studies are needed to confirm whether the HLA-DRB1*15 association with secondary SS in RA is common to Spanish and other ethnic populations.
Identification and Functional Expression of a New Member of the Mammalian Kex2-Like Processing Endoprotease Family: Its Striking Structural Similarity to PACE41 (1993)

We used the polymerase chain reaction to identify a mouse cDNA which represented a new member of a growing class of mammalian endoproteases homologous to the yeast Kex2 protease involved in the processing of precursor proteins. This cDNA encoded a 915-residue protein, designated as PC6, containing a subtilisin-like catalytic domain closely related to those of other Kex2-like members (furin, PC2, PC1/3, PC4, and PACE4). It exhibited striking sequence similarity to PACE4 and contained similar protein domains, such as the COOH-terminal Cys-rich region. Northern blot analysis revealed that PC6 mRNA, as with furin and PACE4 mRNAs, was expressed in various tissues and cell lines, with the highest level in the intestine. Transfection experiments revealed that PC6 was capable of cleaving precursors at dibasic sites. These observations suggest that PC6 is a candidate for a processing endoprotease responsible for the maturation of gastrointestinal peptides.
A mutation in Arabidopsis cytochrome b5 reductase identified by high‐throughput screening differentially affects hydroxylation and desaturation (2006)

As a model for analyzing the production of novel fatty acids in oilseeds, we used the genetic and molecular techniques available for Arabidopsis to characterize modifying mutations affecting the accumulation of hydroxy fatty acids in the seeds of Arabidopsis plants that express a transgene for the castor bean fatty acid hydroxylase, FAH12. We developed a high-throughput analytical system and used it to identify three complementation classes of mutations with reduced hydroxy fatty acid accumulation from among Arabidopsis M3 seed samples derived from chemical mutagenesis. We identified one of the mutations by positional cloning as a single base pair change in a gene encoding NADH:cytochrome b5 reductase (CBR1, At5g17770). When expressed in yeast, the mutant form of the enzyme was less active and less stable than the wild-type enzyme. Characterization of homozygous mutant lines with and without the FAH12 transgene (FAH12 cbr1-1 and cbr1-1, respectively) indicated that the only detectable consequence of the cbr1-1 mutation was on desaturase and hydroxylase reactions in the developing seed. The leaf and root fatty compositions, as well as the growth, development and seed production of mutant plants were indistinguishable from wild type. Interestingly, while the cbr1-1 mutation reduced the accumulation of hydroxy fatty acids in seeds by 85%, the effects on 18:1 and 18:2 desaturation reactions were much less (<25% and <60%, respectively). These results suggest that there is competition in developing seeds among the several reactions that utilize reduced cytochrome b5.
Locus Ceruleus Activation Suppresses Feedforward Interneurons and Reduces β-γ Electroencephalogram Frequencies While It Enhances θ Frequencies in Rat Dentate Gyrus (2005)

The locus ceruleus is activated by novel stimuli, and its activation promotes learning and memory. Phasic activation of locus ceruleus neurons by glutamate enhances the dentate gyrus population spike amplitude and results in long-term potentiation of synaptic responses recorded after 24 h. Cholinergic activation of locus ceruleus neurons increases hippocampal . At the level of the cellular network, it is not clear how the potentiating effects of norepinephrine are mediated. Previous studies show that exogenous norepinephrine enhances inhibitory interneuron firing in the dentate gyrus. This finding appears at odds with evidence for potentiation. In this study, natural release of norepinephrine was induced by glutamate activation of locus ceruleus while we recorded EEGs and physiologically identified interneurons in the dentate gyrus of urethane-anesthetized rats. Feedforward neurons were inhibited (approximately 1-2 min) by locus ceruleus activation. Feedback interneurons showed both increased and decreased activity, whereas granule cells increased firing as predicted by evoked potential studies. EEG results replicated an increase in power (4-8 Hz) with locus ceruleus activation, but the effect with glutamatergic locus ceruleus activation was transient (approximately 1-2 min). Beta-gamma Frequencies were also transiently suppressed. Together, the data suggest that locus ceruleus activation enhances the throughput of concomitant sensory input by reducing feedforward inhibitory interneuron activity, which may reduce "binding" in existing cell assemblies, and enhances the conditions for synaptic plasticity through disinhibition, promotion of 4-8 Hz , and noradrenergic potentiation to facilitate the building of new representations.
