Turning the Web Into a Computer (1996)

The explosive growth of the World Wide Web, along with the evolution of the HTTP, HTML, and CGI standards, has enabled many applications which would not have been feasible just a few years ago. We believe that this evolution will eventually lead to support for general-purpose distributed computing over the Web. Such computation minimally requires transparent access to: i) local and remote files, ii) private and public data, and iii) local and remote computation. In this paper, we demonstrate that these requirements can be met by integrating simple protocols from existing distributed systems into the Web. In turn, we show that adding these capabilities can qualitatively improve the utility of the Web by enabling a whole new class of distributed applications. 1 Introduction Widespread adoption of the World Wide Web&amp;apos;s standards has radically changed the use of the Internet, and this impact is increasing as the Web evolves. To date, Web access has undergone at least three stages of evolu...
Distributed Object Management in Thor. (1992)

Thor is a new object-oriented database management system (OODBMS), intended to be used in heterogeneous distributed systems to allow programs written in different programming languages to share objects in a convenient manner. Thor objects are persistent in spite of failures, are highly likely to be accessible whenever they are needed, and can be structured to reflect the kinds of information of interest to users. Thor combines the advantages of the object-oriented approach with those of database systems: users can store and manipulate objects that capture the semantics of their applications, and can also access objects via queries. Thor is an ongoing project, and this paper is a snapshot: we describe our first design and a partial implementation of that design. This design is primarily concerned with issues related to the implementation of an OODBMS as a distributed system. 1 INTRODUCTION Distributed systems contain different kinds of computers, and users write programs in different...
Sodium Bicarbonate Attenuates Pain on Skin Infiltration with Lidocaine, with or without Epinephrine (1987)

Anesthetics produce pain on skin infiltration (1,2). The relation of this local anesthetic-induced pain to pH of the local anesthetic solution has, however, not been evaluated. Commercial preparations of local anesthetics are prepared as acidic solutions of the salts to promote solubility and stability. Further increases of acidity in local anesthetic solutions containing epinephrine are avoided by the addition of epinephrine to plain lidocaine (3); sodium bicarbonate can also be used to increase pH. Such increases in pH, by increasing the ratio of nonionized to ionized local anesthetic, alter the pharmacologic properties of local anesthetics. For example, addition of sodium bicarbonate to preparations of local anesthetics increases spread and duration of sensory blockade and lessens the time to onset of anesthesia (4,5). The present double-blind, randomized study was designed to determine the relation between pH of anesthetic solutions and production of pain associated with infracutaneous injection of the local anesthetic, lidocaine.
Trial Assessing Individualized Options for Treatment for Breast Cancer: The TAILORx Trial (2008)

Novel genetic profiling tests of breast cancer tissue have been shown to be prognostic for overall survival and predictive of local and distant rates of recurrence in breast cancer patients. One of these tests, Oncotype DXtrade mark, is a diagnostic test comprised of a 21-gene assay applied to paraffin-embedded breast cancer tissue, which allows physicians to predict subgroups of hormone-receptor-positive, node-negative patients who may benefit from hormonal therapy alone or require adjuvant chemotherapy to attain the best survival outcome. The results of the assay are converted to a recurrence score (0-100) that has been found to be predictive of 10- and 15-year local and distant recurrence in node-negative, estrogen-receptor-positive breast cancer patients. Previous studies have shown that patients with high recurrence scores benefit from adjuvant chemotherapy, whereas patients with low recurrence scores do not. To evaluate the ability to guide treatment decisions in the group with a mid-range recurrence score, the North American Cooperative Groups developed the Trial Assessing IndiviuaLized Options for Treatment for breast cancer, a randomized trial of chemotherapy followed by hormonal therapy versus hormonal therapy alone on invasive disease-free survival-ductal carcinoma in situ (IDFS-DCIS) survival in women with node-negative, estrogen-receptor-positive breast cancer with a recurrence score of 11-25. The study was initiated in May 2006 and approximately 4500 patients will be randomized. This article describes the rationale, methodology, statistical ana-lysis and implications of the results on clinical practice.
Detection of Trace Water Vapor Using SiO<i><sub>x</sub></i>-Coated Ball SAW Sensor (2014)

In manufacturing process of semiconductor, blue light emitting diode (LED), and lithium ion battery, detection and monitoring of trace water vapor (<1 µmol/mol) are significantly important techniques. We have been researching about detection of trace water vapor with high speed and sensitivity by using ball surface acoustic wave (SAW) sensor.In this paper, we tried to detect trace water vapor by coating silicon oxide (SiOx) on ball SAW sensor using sol–gel method. It was confirmed that SiOx-coated ball SAW sensor could detect water vapor in a wide range from −95 to 0°C in frost point (0.035–6.0 × 103 µmol/mol in concentration) and its response time to frost point change from −70 to −60°C was one half of that of a chilled-mirror hygrometer.
Preparation and catalytic properties of NR‐stabilized palladium colloids (1994)

Abstract Palladium colloids revealing narrow particle size distributions can be obtained by chemical reduction using tetra–alkylammonium hydrotriorganoborates. Combining the stabilizing agent [NR ] with the reducing agent [BEt 3 H − ] provides a high concentration of the protecting group at the reduction centre. Alternatively, NR 4 X (X = halogen) may be coupled to the metal salt prior to the reduction step: addition of N(octyl) 4 Br to Pd(ac) 2 in THF, for example, evokes an active interaction between the stabilizing agent and the metal salt. Reduction of NR ‐stabilized palladium salts with simple reducing agents such as hydrogen at room temperature yields stable palladium organosols which may be isolated in the form of redispersible powders. The anion of the palladium salt is crucial for the success of the colloid synthesis. Electron microscopy shows that the mean particle size ranges between 1.8 and 4.0 nm. An X–ray–photoelectron spectrscopic examination demonstrated the presence of zerovalent palladium. These palladium colloids may serve as both homogeneous and heterogeneous hydrogenation catalysts. Adsorption of the colloids onto industrially important supports can be achieved without agglomeration of palladium particles. The standard activity of a charcoal catalyst containing 5% of colloidal palladium determined through the cinnamic acid standard test was found to exceed considerably the activity of the conventional technical catalysts. In addition, the lifespan of the catalyst containing a palladium colloid, isolated from the reduction of [N(octyl) 4 ] 2 PdCl 2 Br 2 with hydrogen, is superior to conventionally prepared palladium/charcoal (Pd/C) catalysts. For example, the activity of a conventional Pd/C catalyst is completely suppressed after 38×10 3 catalytic cycles per Pd atom, whereas the colloidal Pd/C catalyst shows activity even after 96times;10 3 catalytic cycles.
Optimal Medical Therapy with or without PCI for Stable Coronary Disease (2007)

As an initial management strategy in patients with stable coronary artery disease, PCI did not reduce the risk of death, myocardial infarction, or other major cardiovascular events when added to optimal medical therapy. (ClinicalTrials.gov number, NCT00007657 [ClinicalTrials.gov].).
P‐glycoprotein is an independent prognostic factor predicting relapse in childhood acute lymphoblastic leukaemia: results of a 6‐year prospective study (1999)

P-glycoprotein (P-gp), a cellular drug-efflux pump, is thought to be one of the major causes of multidrug resistance (MDR) in malignancies. Since therapeutic strategies are being developed to circumvent drug resistance by inhibiting P-gp function, large prospective studies evaluating the clinical relevance of P-gp in childhood acute lymphoblastic leukaemia (ALL) are warranted. P-gp expression was evaluated over a period of 6 years in 102 consecutive patients with de novo childhood ALL and in 35 children with relapse of ALL. Bone marrow and blood smears were studied immunocytochemically with two monoclonal antibodies at initial diagnosis and at relapse. P-gp expression was found in 14 (14%) patients at initial diagnosis. After induction treatment, complete remission was achieved in 100/102 patients (98%), of whom 19 relapsed. Cumulative event-free survival was significantly higher in the P-gp-negative group compared with the P-gp-positive population (Logrank P = 0.02). Multivariate analysis showed the results to be independent of age, WBC count and karyotype, and concomitantly underlined the importance of MDR1 phenotype detection in childhood ALL. P-gp expression was more frequently found at relapse (34%) than at primary diagnosis (P = 0.01). In the relapsed patient group, P-gp-positive patients had a 2-fold greater risk for adverse clinical outcome than the P-gp-negative relapsed patients. P-gp expression was not induced by exposure to previous chemotherapy since the majority of P-gp-negative patients remained negative at relapse. P-glycoprotein expression in newly diagnosed childhood ALL is an independent adverse prognostic parameter with a predictive value for relapse.
The Yin and Yang of cell cycle progression and differentiation in the oligodendroglial lineage (2006)

In white matter disorders such as leukodystrophies (LD), periventricular leucomalacia (PVL), or multiple sclerosis (MS), the hypomyelination or the remyelination failure by oligodendrocyte progenitor cells involves errors in the sequence of events that normally occur during development when progenitors proliferate, migrate through the white matter, contact the axon, and differentiate into myelin-forming oligodendrocytes. Multiple mechanisms underlie the eventual progressive deterioration that typifies the natural history of developmental demyelination in LD and PVL and of adult-onset demyelination in MS. Over the past few years, pathophysiological studies have mostly focused on seeking abnormalities that impede oligodendroglial maturation at the level of migration, myelination, and survival. In contrast, there has been a strikingly lower interest for early proliferative and differentiation events that are likely to be equally critical for white matter development and myelin repair. This review highlights the Yin and Yang principles of interactions between intrinsic factors that coordinately regulate progenitor cell division and the onset of differentiation, i.e. the initial steps of oligodendrocyte lineage progression that are obviously crucial in health and diseases.
Immunological Characteristics of Amniotic Epithelium (2006)

We review recent experimental evidence of the immunosuppressive and immunogenic potential of amniotic epithelial cells. Since cryopreserved amniotic membrane (AM) has been used in clinical applications, much research has focused on the beneficial effects of amniotic stromal matrix rather than on the function of viable amniotic cells. However, viable human amniotic epithelial cells (HAECs) have been shown to elicit beneficial effects on secretion of anti-inflammatory factors. Topical application of culture supernatant from HAECs leads to profound suppression of suture-induced neovascularization in cornea and fewer major histocompatibility complex (MHC) class II antigen-presenting cells (APCs) in inflamed cornea after thermal cautery. Furthermore, expression of interleukin (IL)-1beta mRNA was suppressed in cauterized cornea. These results suggest that HAECs are a source of soluble anti-inflammatory factors that suppress corneal inflammation. However, viable amniotic epithelial cells display antigenicity and immunogenicity as allografts. Fresh allogeneic amniotic epithelium (AE) expresses MHC class I antigens and sensitizes recipients when placed in the eye, although long-term memory of allo-specific delayed hypersensitivity (DH) was not acquired. Allogeneic AE was clearly vulnerable to acute immune rejection in specifically sensitized recipients and recipients of repeated AE transplantation. We therefore suggest that immunogenicity of AE should not be ignored, and use of AM from different donor placentas should be emphasized when repeated AM transplantation is required in patients clinically.
Identification of proteins encoded by the L1 and L2 open reading frames of human papillomavirus 1a (1987)

The human papillomavirus 1 (HPV-1) virion is composed of two virally encoded proteins: a 57,000-molecular-weight polypeptide (57K polypeptide), which is the product of the L1 open reading frame (ORF), and a 78K polypeptide, which is derived from the L2 ORF. The 57K (L1) product, which represents the major structural component, appears to be disulfide cross-linked in virus particles. The 78K (L2) protein is a minor component of the virion and does not appear to be disulfide linked either to the L1 gene product or to itself. Analysis of virus particles banding at different buoyant densities revealed differences in the L2 content of heavy-full and light-full virions. Antiserum prepared against a bacterially expressed fragment of the L1 ORF was found by immunofluorescence to cross-react with HPV-2 and bovine papillomavirus 1 virions in wart sections. No cross-reactivity was observed with antisera prepared against either the N- or C-terminal halves of the L2-encoded protein. Similarly, antisera prepared against purified virus particles (disrupted and nondisrupted) reacted only with an expressed fragment of the L1 ORF and not with either L2-encoded polypeptides or proteins derived from the E1, E2, E4, E6, or E7 ORFs. This indicates that the L1 protein contains the papillomavirus common antigens.

The PEG hydrogel sealant provides a safe and effective watertight closure when used as an adjunct to sutured dural repair during cranial surgery.
Identification of the Substrate Specificity-conferring Amino Acid Residues of 4-Coumarate:Coenzyme A Ligase Allows the Rational Design of Mutant Enzymes with New Catalytic Properties (2001)

4-Coumarate:coenzyme A ligases (4CLs) generally use, in addition to coumarate, caffeate and ferulate as their main substrates. However, the recently cloned Arabidopsis thaliana isoform At4CL2 is exceptional because it has no appreciable activity with ferulate. On the basis of information obtained from the crystal structure of the phenylalanine-activating domain of gramicidin S-synthetase, 10 amino acid residues were identified that may form the substrate binding pocket of 4CL. Among these amino acids, representing the putative "substrate specificity motif," only one residue, Met(293), was not conserved in At4CL2, compared with At4CL1 and At4CL3, two isoforms using ferulate. Substitution of Met(293) or Lys(320), another residue of the putative substrate specificity motif, which in the predicted three-dimensional structure is located in close proximity to Met(293), by smaller amino acids converted At4CL2 to an enzyme capable of using ferulate. The activity with caffeate was not or only moderately affected. Conversely, substitution of Met(293) by bulky aromatic amino acids increased the apparent affinity (K(m)) for caffeate up to 10-fold, whereas single substitutions of Val(294) did not affect substrate use. The results support our structural assumptions and suggest that the amino acid residues 293 and 320 of At4CL2 directly interact with the 3-methoxy group of the phenolic substrate and therefore allow a first insight into the structural principles determining substrate specificity of 4CL.
A Viral Nanoparticle with Dual Function as an Anthrax Antitoxin and Vaccine (2007)

The recent use of Bacillus anthracis as a bioweapon has stimulated the search for novel antitoxins and vaccines that act rapidly and with minimal adverse effects. B. anthracis produces an AB-type toxin composed of the receptor-binding moiety protective antigen (PA) and the enzymatic moieties edema factor and lethal factor. PA is a key target for both antitoxin and vaccine development. We used the icosahedral insect virus Flock House virus as a platform to display 180 copies of the high affinity, PA-binding von Willebrand A domain of the ANTXR2 cellular receptor. The chimeric virus-like particles (VLPs) correctly displayed the receptor von Willebrand A domain on their surface and inhibited lethal toxin action in in vitro and in vivo models of anthrax intoxication. Moreover, VLPs complexed with PA elicited a potent toxin-neutralizing antibody response that protected rats from anthrax lethal toxin challenge after a single immunization without adjuvant. This recombinant VLP platform represents a novel and highly effective, dually-acting reagent for treatment and protection against anthrax.
<title>Surgical planning for radical prostatectomies using three-dimensional visualization and a virtual reality display system</title> (1995)

Thousands of radical prostatectomies for prostate cancer are performed each year. Radical prostatectomy is a challenging procedure due to anatomical variability and the adjacency of critical structures, including the external urinary sphincter and neurovascular bundles that subserve erectile function. Because of this, there are significant risks of urinary incontinence and impotence following this procedure. Preoperative interaction with three-dimensional visualization of the important anatomical structures might allow the surgeon to understand important individual anatomical relationships of patients. Such understanding might decrease the rate of morbidities, especially for surgeons in training. Patient specific anatomic data can be obtained from preoperative 3D MRI diagnostic imaging examinations of the prostate gland utilizing endorectal coils and phased array multicoils. The volumes of the important structures can then be segmented using interactive image editing tools and then displayed using 3-D surface rendering algorithms on standard work stations. Anatomic relationships can be visualized using surface displays and 3-D colorwash and transparency to allow internal visualization of hidden structures. Preoperatively a surgeon and radiologist can interactively manipulate the 3-D visualizations. Important anatomical relationships can better be visualized and used to plan the surgery. Postoperatively the 3-D displays can be compared to actual surgical experience and pathologic data. Patients can then be followed to assess the incidence of morbidities. More advanced approaches to visualize these anatomical structures in support of surgical planning will be implemented on virtual reality (VR) display systems. Such realistic displays are `immersive,' and allow surgeons to simultaneously see and manipulate the anatomy, to plan the procedure and to rehearse it in a realistic way. Ultimately the VR systems will be implemented in the operating room (OR) to assist the surgeon in conducting the surgery. Such an implementation will bring to the OR all of the pre-surgical planning data and rehearsal experience in synchrony with the actual patient and operation to optimize the effectiveness and outcome of the procedure.
Endoglin forms a heteromeric complex with the signaling receptors for transforming growth factor-beta. (1994)

Human endoglin is a dimeric protein that binds transforming growth factor-beta (TGF-beta). A porcine cDNA clone for endoglin was obtained from a porcine uterus cDNA library. The deduced sequence of the primary translated product of endoglin consists of 643 amino acids with a high sequence identity (96%) to human endoglin in the transmembrane and intracellular domains, but with a lower sequence similarity (66%) in the extracellular domain. In contrast to human endoglin, porcine endoglin has no Arg-Gly-Asp tripeptide in its sequence. Antibodies, raised against a peptide corresponding to the intracellular domain of porcine endoglin, immunoprecipitated an 84-kDa protein under reducing condition and a 130-kDa protein under nonreducing condition in porcine aortic endothelial cells. Porcine endoglin bound TGF-beta 1 and -beta 3 efficiently, but TGF-beta 2 less efficiently. Endoglin was found to be coimmunoprecipitated with TGF-beta receptors type I and/or II by the endoglin antibodies or by TGF-beta receptor II antibodies in the presence of ligand. Thus, endoglin and TGF-beta receptors I and/or II most likely formed a heteromeric receptor complex. Endoglin was phosphorylated on serine residue(s), which did not change after stimulation by TGF-beta 1. These results revealed that endoglin is a phosphorylated protein which forms a heteromeric complex with signaling receptors for TGF-beta.
Co‐operative effect of the isoforms of type III antifreeze protein expressed in Notched‐fin eelpout, Zoarces elongatus Kner (2004)

We found that Notched-fin eelpout, which lives off the north east coast of Japan, expresses an antifreeze protein (AFP). The liver of this fish contains DNAs that encode at least 13 type III AFP isoforms (denoted nfeAFPs). The primary sequences of the nfeAFP isoforms were categorized into SP- and QAE-sephadex binding groups, and the latter were further divided into two subgroups, QAE1 and QAE2 groups. Ice crystals observed in HPLC-pure nfeAFP fractions are bipyramidal in shape with different ratios of c and a axes, suggesting that all the isoforms are able to bind ice. We expressed five recombinant isoforms of nfeAFP and analyzed the thermal hysteresis (TH) activity of each as a function of protein concentration. We also examined the change in activity on mixing the isoforms. TH was estimated to be 0.60 degrees C for the QAE1 isoform, 0.11 degrees C for QAE2, and almost zero for the SP isoforms when the concentrations of these isoforms was standardized to 1.0 mm. Significantly, the TH activity of the SP isoforms showed concentration dependence in the presence of 0.2 mm QAE1, indicating that the less active SP isoform becomes 'active' when a small amount of QAE1 is added. In contrast, it does not become active on the addition of another SP isoform. These results suggest that the SP and QAE isoforms of type III AFP have different levels of TH activity, and they accomplish the antifreeze function in a co-operative manner.
Receptor accessory folding helper enzymes: the functional role of peptidyl prolyl cis/trans isomerases (2001)

Receptor accessory peptidyl prolyl cis/trans isomerases (PPIases) of the FKBP and cyclophilin types form receptor heterocomplexes with different stabilities. PPIases have been found to associate with other receptor heterocomplex constituents via either proline-directed active sites or additional domains of the enzymes. The single-domain PPIases FKBP12 and FKBP12.6 are shown to interact with receptor protein kinases and calcium channels at their active sites. In contrast, heterooligomeric nuclear receptors contain multi-domain PPIases like FKBP51, FKBP52 or cyclophilin 40 that directly interact with the chaperone hsp90 via the tetratricopeptide repeat modules of the folding helper enzymes. PPIases play a critical role in the functional arrangement of components within receptor heterocomplexes.
