Bayesian probit regression model for the diagnosis of pulmonary fibrosis: proof-of-principle (2011)

This study represents the first use of BPR on whole lung tissue; previously, BPR was primarily used to develop predictive models for cancer. This also represents the first report of an independently validated IPF gene expression signature. In summary, BPR is a promising tool for the development of gene expression signatures from non-neoplastic lung tissue. In the future, BPR might be used to develop definitive diagnostic gene signatures for IPF, prognostic gene signatures for IPF or gene signatures for other non-neoplastic lung disorders such as bronchiolitis obliterans.
Purified high-dose anthocyanoside oligomer administration improves nocturnal vision and clinical symptoms in myopia subjects (2005)

The aim of the present study was to determine the effect of purified high-dose anthocyanoside oligomer administration on nocturnal visual function and clinical symptoms in low-to-moderate myopia subjects. The study was a randomized, double-blind, placebo-controlled trial and involved sixty subjects with asthenopia and refractive errors between -1.00 and -8.00 diopters in both eyes. Thirty subjects were administered a purified high-dose anthocyanoside oligomer (100 mg tablet comprising 85 % anthocyanoside oligomer), and thirty were given a placebo in tablet form twice daily for 4 weeks. Prior to the treatment, the placebo and anthocyanoside groups were similar in terms of age and contrast sensitivity. Before and after treatment, subjects completed a questionnaire to determine their clinical symptoms and were also assessed for nocturnal visual function using contrast sensitivity testing. Questionnaire data analysis showed that, following treatment, twenty-two (73.3 %) anthocyanoside subjects showed improved symptoms, whereas only one placebo subject showed an improvement (Fisher's exact test, P<0.0001). Contrast sensitivity levels according to each cycle per degree significantly improved in the anthocyanoside group and remained stable in the placebo group. The mean contrast sensitivity change in the anthocyanoside group was 2.41 (SD) 1.91, compared with -0.66 (SD) 2.66 dB for the placebo group (unpaired Student's t test, P<0.0001). At all cycle per degree levels, contrast sensitivity changes in the anthocyanoside group were better than in the placebo group (unpaired Student's t test, P<0.05). The present data show that the administration of anthocyanoside oligomer appears to improve subjective symptoms and objective contrast sensitivity in myopia subjects with asthenopia.
A Monosaccharide Residue Is Sufficient to Maintain Mouse and Human IgG Subclass Activity and Directs IgG Effector Functions to Cellular Fc Receptors (2015)

Immunoglobulin G (IgG) glycosylation modulates antibody activity and represents a major source of heterogeneity within antibody preparations. Depending on their glycosylation pattern, individual IgG glycovariants present in recombinant antibody preparations may trigger effects ranging from enhanced pro-inflammatory activity to increased anti-inflammatory activity. In contrast, reduction of IgG glycosylation beyond the central mannose core is generally believed to result in impaired IgG activity. However, this study reveals that a mono- or disaccharide structure consisting of one N-acetylglucosamine with or without a branching fucose residue is sufficient to retain the activity of the most active human and mouse IgG subclasses in vivo and further directs antibody activity to cellular Fcγ receptors. Notably, the activity of minimally glycosylated antibodies is not predicted by in vitro assays based on a monomeric antibody-Fcγ-receptor interaction analysis, whereas in vitro assay systems using immune complexes are more suitable to predict IgG activity in vivo.
Expression of M‐twist during postimplantation development of the mouse (1995)

The murine homologue of the Drosophila twist gene has been shown to be essential for head mesenchyme formation and to act as an inhibitor of muscle differentiation. This paper presents a detailed analysis of M-twist expression patterns from day 7 post coitum (p.c.) to day 18 p.c., indicating a more general function of the M-twist gene. At day 7 p.c., M-twist is expressed in the mesoderm outside the primitive streak. Later M-twist message is predominantly found in the somites, the head mesenchyme, the branchial arches, the limbs, and in the mesenchyme underneath the epidermis. Beginning at day 8 p.c., M-twist is mainly expressed in undifferentiated cells committed to muscle and cartilage development: this expression is consistent with a suggested role of M-twist in inhibiting overt muscle and cartilage differentiation. However, during organogenesis, M-twist is expressed in several areas of mesenchyme-epithelia interactions, suggesting additional tissue specific functions.
Simulation of Metal–Ligand Self-Assembly into Spherical Complex M6L8 (2012)

Molecular dynamics simulations were performed to study the self-assembly of a spherical complex through metal-ligand coordination interactions. M(6)L(8), a nanosphere with six palladium ions and eight pyridine-capped tridentate ligands, was selected as a target system. We successfully observed the spontaneous formation of spherical shaped M(6)L(8) cages over the course of our simulations, starting from random initial placement of the metals and ligands. To simulate spontaneous coordination bond formations and breaks, the cationic dummy atom method was employed to model nonbonded metal-ligand interactions. A coarse-grained solvent model was used to fill the gap between the time scale of the supramolecular self-assembly and that accessible by common molecular dynamics simulation. The simulated formation process occurred in the distinct three-stage (assembly, evolution, fixation) process that is well correlated with the experimental results. We found that the difference of the lifetime (or the ligand exchange rate) between the smaller-sized incomplete clusters and the completed M(6)L(8) nanospheres is crucially important in their supramolecular self-assembly.
Suppressive Effects of Eugenol and Ginger Oil on Arthritic Rats (1994)

This study examined the effect of eugenol and ginger oil on severe chronic adjuvant arthritis in rats. Severe arthritis was induced in the right knee and right paw of male Sprague-Dawley rats by injecting 0.05 ml of a fine suspension of dead Mycobacterium tuberculosis bacilli in liquid paraffin (5 mg/ml). Eugenol (33 mg/kg) and ginger oil (33 mg/kg), given orally for 26 days, caused a significant suppression of both paw and joint swelling. These findings suggest that eugenol and ginger oil have potent antiinflammatory and/or antirheumatic properties.
A short course on computer viruses (1991)

From the Publisher:
Here is an outstanding opportunity to learn about viruses from the internationally acclaimed pioneer in the field who actually coined the phrase computer virus. This new edition of Cohen's classic work has been updated and expanded to nearly double its original size and now includes entirely new chapters on LAN viruses, international viruses, and good viruses (including code). As entertaining as it is thorough, the text is enlivened by Cohen's down-to-earth wit and his many fascinating anecdotes and heretofore unpublished historical facts about viruses. Both broad in its coverage and deep in its consideration, it includes dozens of lucid explanations and examples that amicably guide the reader through the complex, often convoluted subject matter. Hailed as a tour de force, Cohen's discussion of defensive strategies reveals many of the stumbling blocks that often trip readers up. Among the breakthroughs and exciting new developments you'll find only in this book are a new analysis of the epidemiology of viruses; new forms of virus evolution that will render most current defenses useless; new strategies and tactics in virus defenses; and new analyses of synergistic effects in attack and defense.
The Disease Model of Addiction (2011)

The disease model of addiction describes an addiction as a lifelong disease involving biologic and environmental sources of origin. The traditional medical model of disease requires only that an abnormal condition be present that causes discomfort, dysfunction, or distress to the individual afflicted. The contemporary medical model attributes addiction, in part, to changes in the brain's mesolimbic pathway. The medical model also takes into consideration that such disease may be the result of other biologic, psychologic, or sociologic entities despite an incomplete understanding of the mechanisms of these entities.
Bradykinin receptor number and sensitivity to ligand stimulation of mitogenesis is increased by expression of a mutant ras oncogene (1989)

Bradykinin is a nine amino acid peptide of the kinin family believed to play a role in pain mediation and in the regulation of blood pressure, fluid balance and smooth muscle contraction. Here we demonstrate that bradykinin is also a potent mitogen for a mutant Ha-ras-transfected cell line, Rat 13. The Rat 13 cells display two binding sites for bradykinin: a moderate number (52,000) of high affinity sites (Kd = 4.9 nM) co-exist with a much smaller number (1100) of very high-affinity sites (Kd = 2.7 pM). Ligand binding stimulates mitogenesis through the lower affinity receptors, which are classified as B2. These receptors are down-regulated in response to ligand. In contrast, Rat 1 cells (the cell line from which Rat 13 was derived) have only 4000 receptors per cell in total and respond weakly to bradykinin as a mitogen. Thus, expression of a mutant ras protein in Rat 13 cells increases their expression of the bradykinin receptor and their sensitivity to ligand stimulation of mitogenesis. Additional binding studies demonstrate that human A431 epithelial cells and Swiss mouse 3T3 fibroblasts also possess high-affinity sites for bradykinin.
Megakaryocytes promote murine osteoblastic HSC niche expansion and stem cell engraftment after radioablative conditioning (2013)

Successful hematopoietic stem cell (HSC) transplantation requires donor HSC engraftment within specialized bone marrow microenvironments known as HSC niches. We have previously reported a profound remodeling of the endosteal osteoblastic HSC niche after total body irradiation (TBI), defined as relocalization of surviving megakaryocytes to the niche site and marked expansion of endosteal osteoblasts. We now demonstrate that host megakaryocytes function critically in expansion of the endosteal niche after preparative radioablation and in the engraftment of donor HSC. We show that TBI-induced migration of megakaryocytes to the endosteal niche depends on thrombopoietin signaling through the c-MPL receptor on megakaryocytes, as well as CD41 integrin-mediated adhesion. Moreover, niche osteoblast proliferation post-TBI required megakaryocyte-secreted platelet-derived growth factor-BB. Furthermore, blockade of c-MPL-dependent megakaryocyte migration and function after TBI resulted in a significant decrease in donor HSC engraftment in primary and competitive secondary transplantation assays. Finally, we administered thrombopoietin to mice beginning 5 days before marrow radioablation and ending 24 hours before transplant to enhance megakaryocyte function post-TBI, and found that this strategy significantly enhanced donor HSC engraftment, providing a rationale for improving hematopoietic recovery and perhaps overall outcome after clinical HSC transplantation.

Angiogenesis in Health and Disease: Insights into Basic Mechanisms and Therapeutic Opportunities (2002)

Angiogenesis, the process that leads to the formation of new blood vessels or neovascularization, continues to be a topic of major scientific and public interest. As knowledge of the molecular mechanisms that regulate neovascularization continues to emerge, there is increasing hope that new discoveries will lead to newer therapies that target angiogenesis as a reliable option for disease therapy. For example, it may be possible to develop strategies that, on the one hand, are designed to limit angiogenesis for the treatment of chronic diseases such as cancer or rheumatoid arthritis and, on the other, to promote angiogenesis in the ischemic heart or diabetic limb. With the emergence of tissue engineering as a discipline, it has become increasingly clear that long-term success in organ and tissue reconstruction will depend on the ability to develop a stable, renewable supply of blood vessels. In this review, I will provide a brief overview of this remarkably versatile biological response and discuss how recent discoveries in the field of angiogenesis have influenced the development of novel therapies, forced a reconsideration of conventional therapies, and revolutionized approaches to organ and tissue reconstruction.
Selective inhibition of synthesis of enzymes for de novo fatty acid biosynthesis by an endotoxin-induced mediator from exudate cells. (1983)

An endotoxin-induced mediator from exudate cells markedly suppresses the activities of the key enzymes for de novo fatty acid biosynthesis--acetyl-CoA carboxylase [acetyl-CoA:carbon dioxide ligase (ADP-forming), EC 6.4.1.2] and fatty acid synthetase--in differentiating 3T3-L1 murine preadipocytes. The loss in activity, at least in part, appears to be due to a specific effect on the synthesis of the enzymes, as determined by a decreased incorporation of [35S]methionine into immunoadsorbable acetyl-CoA carboxylase and fatty acid synthetase when the cells were exposed to the mediator. During this exposure, the radiolabeling of proteins with [35S]methionine in a particulate fraction was decreased by nearly 50% with little change in the soluble protein fraction. Sodium dodecyl sulfate/polyacrylamide gel analysis of the labeled protein indicated no major disturbances of protein synthesis in general; however, the syntheses of specific proteins in both the soluble and particulate fractions were enhanced or depressed. The present study demonstrates that endotoxin promotes the release of a mediator from exudate cells that regulates key anabolic activities in adipose cells.

A Miniaturized, Power-Efficent Stimulator Output Stage Based on the Bridge Rectifier Circuit (2006)

Nerves can be artificially stimulated in people paralyzed after spinal cord injury to restore muscle function. The miniaturization of implantable stimulators is currently limited by the size of the large off-chip blocking capacitors that are used to ensure that no direct current flows between the electrodes in the event of a semiconductor failure. This paper proposes a new stimulator output stage circuit utilizing the principle of high-frequency current switching which allows the blocking capacitors to be integrated on-chip. The new design is based on the bridge rectifier circuit and achieves an increase of about 50% in power efficiency over a previous circuit. The approach has been verified by SPICE simulations in a 1mum SOI-CMOS technology
Neutral Endopeptidase Regulates C-Type Natriuretic Peptide Metabolism But Does Not Potentiate Its Bioactivity In Vivo (1997)

C-type natriuretic peptide (CNP) is a newly described 22-amino acid peptide of endothelial and renal cell origin with selective cardiovascular actions. Recent in vitro studies have reported that CNP is the most susceptible of all natriuretic peptides to enzymatic degradation by neutral endopeptidase 24.11 (NEP). The present study was undertaken to define the role of NEP in total and regional CNP metabolism and the modulatory actions of NEP inhibition on the biological actions of CNP. CNP (10 ng x kg(-1) x min(-1)) followed by candoxatrilat (240 microg x kg(-1) bolus and 8 microg x kg(-1) x min(-1)), a potent and selective NEP inhibitor, was administered intravenously to a group of anesthetized mongrel dogs (group 1) to permit calculation of total metabolic clearance rate (MCR); results were compared with those in a group receiving vehicle infusion followed by candoxatrilat (group 2; both groups, n=7). NEP inhibition increased circulating CNP achieved by exogenous infusion and reduced total MCR in group 1. The regional CNP MCRs increased after CNP administration. While the pulmonary MCR did not change during concomitant candoxatrilat infusion, renal MCR was suppressed. Hemodynamic changes were not different between groups. A mild natriuretic and diuretic effect in association with an increase in circulating and urinary ANP levels was not different between groups. Urinary CNP excretion did not change with CNP infusion but markedly increased after NEP inhibition. We conclude that (1) circulating CNP achieved by exogenous CNP infusion is regulated by NEP in vivo, (2) regional MCRs are heterogeneous with NEP inhibition, (3) NEP inhibition does not potentiate acute cardiovascular actions of CNP, and (4) a mild natriuretic and diuretic effect observed with CNP and NEP inhibition may be ANP dependent.
Metabolic Engineering Plant Seeds with Fish Oil-Like Levels of DHA (2012)

The amount of DHA described in this study exceeds the 12% level at which DHA is generally found in bulk fish oil. This is a breakthrough in the development of sustainable alternative sources of DHA as this technology should be applicable in oilseed crops. One hectare of a Brassica napus crop containing 12% DHA in seed oil would produce as much DHA as approximately 10,000 fish.
Solar neutrinos, SNO and SNOLAB (2006)

The Sudbury Neutrino Observatory is a 1000 tonne heavy water Cherenkov detector situated 2 km underground in INCO's Creighton mine near Sudbury, Ontario, Canada. In the first two phases of the project reported to date, the charged current reaction on deuterium has been used to measure the flux and energy spectrum of solar electron neutrinos and the neutral current reaction has been used to measure the total flux of active neutrinos. Clear evidence of neutrino flavour change has been observed and the total active flux is found to be in agreement with solar model calculations. The experimental third phase with an array of neutron detectors is in progress. The expansion of the underground laboratory to create an international facility known as SNOLAB will be completed in 2007. A number of international experiments for the future detection of lower energy solar neutrinos, geo-neutrinos, dark matter and double beta decay are described.
Silicon bipolar device structures for digital applications: technology trends and future directions (1995)

The double-polysilicon self-aligned bipolar device structure has come a long way since its first inception, but there is still room for further scaling of this structure and continued improvements in performance. An analysis of the current state-of-the-art double-poly structure leads naturally to a discussion of future trends and technologies necessary to continue scaling into the sub-0.25 /spl mu/m regime. In addition, it has become highly desirable to extend bipolar processes in new directions to take advantage of the opportunities offered by emerging materials technologies, such as bonded silicon-on-insulator films and medium or low temperature Si and SiGe epitaxy. Opportunities also exist for high-performance bipolars in BiCMOS technology and in complementary bipolar processes for low-power, high-speed digital applications. These extensions beyond "conventional" bipolar technology will be discussed in terms of their requirements and the device structures that are evolving to match these needs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The Diagnosis of Renovascular Hypertension with Technetium-99m-Ethylenedicysteine Captopril Scintigraphy (1996)

This preliminary study demonstrates that 99mTc-EC has good potential for the diagnosis of renovascular hypertension and that a single diagnostic criteria, specifically a rising renogram curve, seems adequate. However, the authors' initial results should be confirmed in a broader patient population.
Molecular cloning and expression of a cDNA encoding a protein detected by the ki antibody from an ovarian carcinoma (OVCAR‐3) cell line (1994)

MAb KI recognizes a cell-surface glycoprotein (MW approximately 40 kDa) present in ovarian carcinomas, malignant mesotheliomas, squamous-cell carcinomas and normal mesothelial cells. In this study, expression screening was used to isolate cDNA clones encoding an antigen recognized by MAb KI from a cDNA library made from a human ovarian carcinoma cell line (OVCAR-3). Subsequently, other clones were isolated by DNA hybridization using a cDNA probe derived from one of the initial clones. The sequence of all the clones was similar. The longest cDNA contains 2,444 base pairs, and encodes a polypeptide of 263 amino acids with a calculated molecular weight of 30,511 daltons. The nucleotide sequence and deduced amino-acid sequence of the protein show no homology to other sequences in current data bases. In vitro translation of RNA transcripts from the cDNA inserts yielded polypeptides of 29 and 30 kDa. Similar-sized proteins were obtained upon expression of the cDNA in Escherichia coli, and these proteins were reactive with MAb KI. The protein(s) expressed in E. coli were purified and used to make rabbit or mouse antisera. These antisera reacted strongly with a soluble cytosolic protein in OVCAR-3 cells, but not with the membrane-bound antigen. Soluble cytosolic proteins of a similar size, recognized with MAb KI, were found in OVCAR-3 and N87 (gastric cancer) cells but not in 10 other cancer cell lines. These data indicate that the cloned cDNA encodes a cytosolic protein that reacted with MAb KI. This soluble protein is expressed only in cells containing the CAKI surface glycoprotein, suggesting that the 2 proteins could be structurally related.
