Human Endometrial Endothelial Cells: Isolation, Characterization, and Inflammatory-Mediated Expression of Tissue Factor and Type 1 Plasminogen Activator Inhibitor1 (2000)

Binding of Ulex europaeus lectin to microvessels was used to isolate endothelial cells from cycling human endometrium. Cultured human endometrial endothelial cells (HEECs) exhibited endothelial cell-specific characteristics such as tube formation on a basement membrane matrix and sequestration of acetylated low-density lipoprotein. Markers for potentially contaminating epithelial, stromal, smooth muscle, and bone marrow-derived cells were not detected in the HEEC cultures. Basal and proinflammatory-stimulated immunostaining profiles for endothelial cell-specific adhesion markers, as exemplified by Von Willebrand's factor and E-selectin, were similar for cultured HEECs and human umbilical venous cord endothelial cells (HUVECs). However, HUVECs expressed several extracellular matrix proteins that were absent from cultured HEECs. In the latter, the protein kinase C agonist phorbol myristate acetate transiently enhanced tissue factor (TF) mRNA levels and elicited a more prolonged elevation in TF protein levels, but did not affect plasminogen activator inhibitor-1 (PAI-1) mRNA and protein levels. Inappropriate expression of TF, which initiates hemostasis by generating thrombin, and of PAI-1, which regulates hemostasis by acting as the primary inhibitor of fibrinolysis, can each lead to thrombosis. The differential regulation of TF and PAI-1 expression revealed in the current study emphasizes the importance of using HEECs to evaluate mechanisms regulating the hemostatic/thrombotic balance in human endometrium.
Genetic analysis of early- versus late-stage ovarian tumors. (2001)

In the United States, ovarian cancer is the fourth most common cause of cancer-related deaths among women. The most important prognostic factor for this cancer is tumor stage, or extent of disease at diagnosis. Although women with low-stage tumors have a relatively good prognosis, most women diagnosed with late-stage disease eventually succumb to their cancer. In an attempt to understand early events in ovarian carcinogenesis, and to explore steps in its progression, we have applied multiple molecular genetic techniques to the analysis of 21 early-stage (stage I/II) and 17 advanced-stage (stage III/IV) ovarian tumors. These techniques included expression profiling with cDNA microarrays containing approximately 18,000 expressed sequences, and comparative genomic hybridization to address the chromosomal locations of copy number gains as well as losses. Results from the analysis indicate that early-stage ovarian cancers exhibit profound alterations in gene expression, many of which are similar to those identified in late-stage tumors. However, differences observed at the genomic level suggest differences between the early- and late-stage tumors and provide support for a progression model for ovarian cancer development.
On the alignment of thermotropic nematic and smectic liquid crystals on lecithin coated surfaces (1994)

Abstract The orientation of thermotropic nematic and smectic liquid crystals at monomolecular films of lecithin on glass as well as germanium substrates has been studied by polarizing microscopy and FTIR spectroscopy. Nematic liquid crystals with only a weak tendency to form smectic phases exhibit a dependence of their orientation on the temperature and the packing density of the monolayer which can be explained by a sterical model. Liquid crystals in the smectic A phase as well as nematics with a strong tendency to build up smectic layers, however, align homeotropically, independent on the packing density of the lecithin film and the temperature. This can be understood as a screening of the lecithin film properties by the smectic‐like boundary layers of the nematic liquid crystal.
CLINICAL PRACTICE GYNAECOLOGY COMMITTEE MEMBERS (2001)

Objective: It is estimated that nine to 30 percent of reproductive age women suffer from menorrhagia. The prevalence increases with age, peaking just prior to menopause. Menorrhagia and uterine fibroids account for up to 75 percent of all hysterectomies performed worldwide. This guideline provides recommendations to gynaecologists and other health care providers in the diagnosis and management of abnormal uterine bleeding, incorporating the current evidence. Options: Diagnostic tools and medical and surgical alternatives to management are reviewed and current evidence is presented. Evidence: Medline, Embase, and the Cochrane database were
Rapid, Nondestructive Estimation of Surface Polymer Layer Thickness Using Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) Spectroscopy and Synthetic Spectra Derived from Optical Principles (2012)

We have developed a rapid, nondestructive analytical method that estimates the thickness of a surface polymer layer with high precision but unknown accuracy using a single attenuated total reflection Fourier transform infrared (ATR FT-IR) measurement. Because the method is rapid, nondestructive, and requires no sample preparation, it is ideal as a process analytical technique. Prior to implementation, the ATR FT-IR spectrum of the substrate layer pure component and the ATR FT-IR and real refractive index spectra of the surface layer pure component must be known. From these three input spectra a synthetic mid-infrared spectral matrix of surface layers 0 nm to 10,000 nm thick on substrate is created de novo. A minimum statistical distance match between a process sample's ATR FT-IR spectrum and the synthetic spectral matrix provides the thickness of that sample. We show that this method can be used to successfully estimate the thickness of polysulfobetaine surface modification, a hydrated polymeric surface layer covalently bonded onto a polyetherurethane substrate. A database of 1850 sample spectra was examined. Spectrochemical matrix-effect unknowns, such as the nonuniform and molecularly novel polysulfobetaine-polyetherurethane interface, were found to be minimal. A partial least squares regression analysis of the database spectra versus their thicknesses as calculated by the method described yielded an estimate of precision of ±52 nm.
Single amino acid substitution altering antigen-binding specificity. (1982)

S107, a phosphocholine-binding myeloma protein, has been cloned in soft agar, and an antigen-binding variant has been isolated and characterized. The variant does not bind phosphocholine attached to carrier or as free hapten in solution but does retain antigenic determinants (idiotypes) of the parent. Chain recombination experiments suggest that the defect in binding is entirely in the heavy chain. Amino acid sequence analysis showed a single substitution--glutamic acid to alanine at position 35--in the first hypervariable or complementarity-determining region. In terms of the three-dimensional model of the phosphocholine-binding site, glutamic acid-35 provides a hydrogen bond to tyrosine-94 of the light chain that appears to be critical for stability of this portion of the binding site. The removal of this bond and the presence of the smaller alanine side chain is thus consistent with the loss in binding activity. These results suggest that small numbers of substitutions in antibodies, such as those presumably introduced by somatic mutation, may in some situations be effective in altering antigen-binding specificity.

A linkage map of mouse chromosome 12: localization of Igh and effects of sex and interference on recombination. (1988)

Inheritance of restriction fragment length polymorphisms associated with four anonymous DNA markers (D12Nyu1, 2, 3 and 4), the Fos proto-oncogene, the Mtv-9 viral integration site, and the alpha 1-antitrypsin (Aat-1) and immunoglobulin heavy chain (Igh) gene families in the mouse has been followed in a backcross experiment. A Bayesian multilocus map-building strategy yielded the map: centromere-D12Nyu2-10 cM-D12Nyu1-2 cM-D12Nyu3-15 cM-Fos-1 cM-D12Nyu4-2 cM-Mtv-9-8 cM-Aat-1-17 cM-Igh-C. A map constructed from male meiotic data was substantially shorter than one constructed from female meiotic data. Significant interference was observed for the linkage group. Two groups of markers studied in recombinant inbred strains of mice could be interpolated into the map: Es-25, D12Nyu10, D12Nyu7 and Apob form a cluster proximal to D12Nyu2, and Ly-18, Ah, and D12Nyu5 form a cluster between D12Nyu2 and D12Nyu1. These data establish an unambiguously ordered linkage group including Igh and Aat-1 that spans most of chromosome 12.
Rising PSA in nonmetastatic prostate cancer. (2007)

Rising prostate-specific antigen (PSA) in nonmetastatic prostate cancer occurs in two main clinical settings: (1) rising PSA to signal failed initial local therapy and (2) rising PSA in the setting of early hormone-refractory prostate cancer prior to documented clinical metastases. Most urologists and radiation oncologists are very familiar with the initial very common clinical scenario, commonly called "biochemical recurrence." In fact, up to 70,000 men each year will have a PSA-only recurrence after failed definitive therapy. The ideal salvage therapy for these men is not clear and includes salvage local therapies and systemic approaches, of which the mainstay is hormonal therapy. Treatment needs to be individualized based upon the patient's risk of progression and the likelihood of success and the risks involved with the therapy. It is unknown how many men per year progress with rising PSA while on hormonal therapy without documented metastases. This rising PSA disease state is sometimes called, "PSA-only hormone-refractory prostate cancer." As in the setting of initial biochemical recurrence, evidence-based treatment options are limited, and taking a risk-stratified approach is justified. In this article, we will explore these prostate cancer disease states with an emphasis on practical, clinically applicable approaches.
Eliminating periodic packet losses in the 4.3-Tahoe BSD TCP congestion control algorithm (1992)

The congestion control algorithm embedded in the 4.3-Tahoe BSD TCP implementation has dramatically improved congestion control over the Internet. However, several recent simulation studies on the dynamics of this algorithm has revealed that the algorithm exhibits clear oscillatory patterns in sending window size, round trip delay and bottleneck queue length. In this paper, we present a new congestion signal scheme and a dual traffic adjustment strategy. Simulation results show that our modifications can eliminate the periodic packet losses and substantially reduce the traffic oscillation.
Existence of ternary complexes of procarboxypeptidase A in the pancreas of some ruminant species (1985)

The existence of procarboxypeptidase A, in the form of a non-covalent ternary complex containing the apparently inactive serine protease (subunit III), has so far been observed only in the ox pancreas. Evidence, obtained in the present study, shows that a ternary complex of procarboxypeptidase A, with a subunit III highly homologous with that of the bovine complex, is also present in two other ruminant species, sheep and goat. The biological significance of these complex forms of procarboxypeptidase A and the consistently high biosynthesis level of the apparently inactive subunit III in all three ruminant species is still unknown. Yet the synthesis of subunit III is not related to the animal diet since in the horse, which is a non-ruminant herbivorous animal, the procarboxypeptidase A is monomeric. Reassociation assays between either bovine subunits II or III and monomeric as well as binary forms of procarboxypeptidase A from various species show that, unlike subunit II, the recognition site for subunit III is highly conserved in all the procarboxypeptidases A and that bovine subunit II is different from porcine chymotrypsinogen C with regard to association.
Efficient Synthesis of Aryl Fluorides (2009)

Creating CF bonds: A novel electrophilic fluorination of aryl and heteroaryl Grignard reagents has been discovered and was used for the efficient synthesis of various aryl fluoride derivatives (see picture; THF=tetrahydrofuran).
Quasi-Phase-Matched Interactions In Lithium Niobate (1990)

Phase-matching nonlinear interactions by periodic variations in the nonlinear susceptibility, quasi-phase-matching, offers advantages in accessible tuning range and in choice of nonlinear coefficients over the conventional birefringent technique. Periodically reversed ferroelectric domains can be used to create monolithic structures with the necessary high-spatial-frequency variations in the nonlinear susceptibility. We present two techniques for the fabrication of periodically-poled lithium niobate crystals, and results for bulk and guided-wave second harmonic generation of blue and green light.
Particle Focusing in Curved Microfluidic Channels (2013)

The decoupled effects of Reynolds and Dean numbers are examined in inertial focusing flows. In doing so, a complex set of inertial focusing behavioral regimes is discovered within curved microfluidic channels over a range of channel Reynolds numbers, curvature ratios and particle confinement ratios. These regimes are characterized by particle migration either towards or away from the center of curvature as the channel Reynolds number is increased. The transition between these two regimes is shown to be a set of conditions where single-point equilibrium position focusing of particles of different sizes is achieved. A mechanism describing the observed motion of particles in such flows is hypothesized incorporating the redistribution of the main flow velocities caused by Dean flow and its effect on the balance forces on suspended particles.
The antibody response in BALB/c mice to the Plasmodium falciparum circumsporozoite repetitive epitope covalently coupled to synthetic lipopeptide adjuvant. (1991)

The repetitive epitope of Plasmodium falciparum circumsporozoite protein (Asn-Ala-Asn-Pro)3 [(NANP)3] was coupled to tripalmitoyl-S-glyceryl-cysteine (P3C) and tripalmitoyl-S-glyceryl-cysteinyl-serine (P3CS). The lipopeptide P3CS is a potent B-cell and macrophage activator. The resulting immunogenic lipopeptides were used for immunization of the low responder mouse strain BALB/c. These low molecular weight conjugates induced specific anti-(NANP)3 IgG and IgM levels without any carrier proteins or admixed adjuvants after a single administration.
Cloning and Characterization of a Gene Cluster Involved in Cyclopentanol Metabolism in Comamonas sp. Strain NCIMB 9872 and Biotransformations Effected by Escherichia coli -Expressed Cyclopentanone 1,2-Monooxygenase (2002)

Cyclopentanone 1,2-monooxygenase, a flavoprotein produced by Pseudomonas sp. strain NCIMB 9872 upon induction by cyclopentanol or cyclopentanone (M. Griffin and P. W. Trudgill, Biochem. J. 129:595-603, 1972), has been utilized as a biocatalyst in Baeyer-Villiger oxidations. To further explore this biocatalytic potential and to discover new genes, we have cloned and sequenced a 16-kb chromosomal locus of strain 9872 that is herein reclassified as belonging to the genus COMAMONAS: Sequence analysis revealed a cluster of genes and six potential open reading frames designated and grouped in at least four possible transcriptional units as (orf11-orf10-orf9)-(cpnE-cpnD-orf6-cpnC)-(cpnR-cpnB-cpnA)-(orf3-orf4 [partial 3' end]). The cpnABCDE genes encode enzymes for the five-step conversion of cyclopentanol to glutaric acid catalyzed by cyclopentanol dehydrogenase, cyclopentanone 1,2-monooxygenase, a ring-opening 5-valerolactone hydrolase, 5-hydroxyvalerate dehydrogenase, and 5-oxovalerate dehydrogenase, respectively. Inactivation of cpnB by using a lacZ-Km(r) cassette resulted in a strain that was not capable of growth on cyclopentanol or cyclopentanone as a sole carbon and energy source. The presence of sigma(54)-dependent regulatory elements in front of the divergently transcribed cpnB and cpnC genes supports the notion that cpnR is a regulatory gene of the NtrC type. Knowledge of the nucleotide sequence of the cpn genes was used to construct isopropyl-beta-thio-D-galactoside-inducible clones of Escherichia coli cells that overproduce the five enzymes of the cpn pathway. The substrate specificities of CpnA and CpnB were studied in particular to evaluate the potential of these enzymes and establish the latter recombinant strain as a bioreagent for Baeyer-Villiger oxidations. Although frequently nonenantioselective, cyclopentanone 1,2-monooxygenase was found to exhibit a broader substrate range than the related cyclohexanone 1,2-monooxygenase from Acinetobacter sp. strain NCIMB 9871. However, in a few cases opposite enantioselectivity was observed between the two biocatalysts.
Information Systems in the Living Room: A Case Study of Personalized Interactive TV Design (2001)

The birth of the World Wide Web (WWW) in 1993, particularly its graphical user interface, offered marketers opportunities that were previously unimaginable. The WWW allows advanced marketing activities and more particularly interactive marketing, as the user is actively involved in responding to the vendorâs promotion campaign. Interactive TV, also referred to as iTV, combines the appeal and mass audience of traditional TV with the interactive features such as those currently available on the Web. Although personalisation is a practice used widely on the Internet by many sites, applying personalisation techniques over interactive television presents a number of difficulties. In this paper we focus on the design and testing process of the User Interface (UI) for the Interactive &amp; Personalized Advertisement TV viewer. We argue that there are a lot of challenges involved in the designing of interactive TV applications. These are related with the differences of the medium from the traditional PC based Information Systems in terms of input and output devices, viewing environment, number of users and low level of expertise in PC usage.
Thermodynamic Consequences of Grafting Enhanced Affinity toward the Mutated Antigen onto an Antibody (2000)

In order to address the mechanism of enhancement of the affinity of an antibody toward an antigen from a thermodynamic viewpoint, anti-hen lysozyme (HEL) antibody HyHEL-10, which also recognize the mutated antigen turkey lysozyme (TEL) with reduced affinity, was examined. Grafting high affinity toward TEL onto HyHEL-10 was performed by saturation mutagenesis into four residues (Tyr(53), Ser(54), Ser(56), and Tyr(58)) in complementarity-determining region 2 of the heavy chain (CDR-H2) followed by selection with affinity for TEL. Several clones enriched have a Phe residue at site 58. Thermodynamic analyses showed that the clones selected had experienced a greater than 3-fold affinity increase toward TEL in comparison with wild-type Fv, originating from an increase in negative enthalpy change. Substitution of HyHEL-10 HTyr(58) with Phe led to the increase in negative enthalpy change and to almost identical affinity for TEL in comparison with mutants selected, indicating that mutations at other sites decrease the entropy loss despite little contribution to the affinity for TEL. These results suggest that the affinity of an antibody toward the antigen is enhanced by the increase in enthalpy change by some limited mutation, and excess entropy loss due to the mutation is decreased by other energetically neutral mutations.
Functional T lymphocytes infiltrate implanted polyvinyl alcohol foams during surgical wound closure therapy (2001)

Vacuum-assisted closure involving the implantation of polyvinyl alcohol foam is a technique recently developed for the treatment of patients suffering from either wound infection or chronic wounds. This method has been shown to improve and accelerate wound healing. However, little is known about the cell populations that infiltrate the foam, and their potential role in resolving the infection and promoting granulation tissue formation. Our study demonstrates that wound-implanted foams are mainly infiltrated with granulocytes, but that mononuclear cells, including macrophages and minor populations of T, B and natural killer lymphocytes, are also present. We show that foam-infiltrating T cells, especially CD4(+) T cells, constitute a phenotypically and functionally heterogeneous population influenced by wound-infecting bacteria. Thus, T lymphocytes could play a role in wound cleansing. In addition, our data indicate that implanted polyvinyl alcohol foams might be suitable microenvironments for manipulating T cell-mediated immune responses in patients.
Statistical characterisation of the real transaction data gathered from electric vehicle charging stations (2018)

Abstract Despite the many environmental benefits that a massive diffusion of electric vehicles (EVs) could bring to the urban mobility and to society as a whole, numerous are the challenges that this could pose to the electricity distribution grid, particularly to its operation and development. While uncoordinated management of EVs can lead to load imbalances, current or voltage variation excess and steep power requests, properly designed and well-coordinated integration approaches can in contrast provide flexibility, hence value, to the whole electrical system. Such step can be achieved only if real data are available and real drivers' behaviours are identified. This paper is based on a real dataset of 400,000 EV charging transactions. It shows and analyses an important set of key figures (charge time, idle time, connected time, power, and energy) depending on driver's behaviour in the Netherlands. From these figures, it emerges a key role of the uncertainty of the relevant variables due to the drivers' behaviour. This requires a statistical characterisation of these variables, which generally leads to multi-modal probability distributions. Thereby, this paper develops a Beta Mixture Model to represent these multi-modal probability distributions. Based on the emerged statistical facts, a number of results and suggestions are provided, in order to contribute to the important debate on the role of EVs to move to a fully decarbonised society.
Molecular analysis of a serotype 8 human astrovirus genome (2000)

Human astroviruses are an important cause of gastroenteritis. As part of a molecular epidemiological study carried out in Mexico a human astrovirus isolate, Yuc-8, was adapted to grow in CaCo-2 cells, and its entire genome was sequenced. A 15 amino acid deletion in ORF1a, which has been associated with adaptation of astroviruses to grow in cells other than CaCo-2, was present in Yuc-8. Comparative sequence analysis of the Yuc-8 ORF2 with reported human astrovirus sequences revealed that this isolate belongs to genotype (serotype) 8. Two distinct domains in ORF2 were observed: an amino-terminal domain (residues 1 to 415), with identities higher than 81% among the strains analysed, and a carboxy-terminal domain (residues 416 to 782) with identities between 36 and 60%. Two non-superimposable phylogenetic trees were generated by separate analysis of these two domains, suggesting that a differential selective pressure is exerted along the structural polyprotein.
Dextran T-500 improves survival and spreading of chick embryo cells in serum-free medium. (1988)

The supplementation of serum-free Eagle's minimal essential medium (EMEM) with Dextran T-500 significantly improves attachment, spreading and survival of chick embryo cells in primary (myoblasts) and secondary (fibroblasts) cultures. These effects were observed in quiescent cultures incubated at 4 degrees C as well as at 37 degrees C. The results suggest that dextran can be used to simplify conditions for research on factors influencing cell proliferation and differentiation in serum-free media.
