Laser method for recording displacement of the heart and chest wall (1984)

Several non-invasive methods are in use for recording mechanocardiograms. In this paper a new laser technique will be presented to measure heart motion, chest wall displacement and other displacement curves of cardiovascular structures. Principles of the laser displacement technique are described. The measurement range within which displacement is sensed, is 32 mm with a detector to object distance of 25 cm and a resolution of 8 micron (digital output) or 16 micron (analogue output). The specific surface of which motion is sensed is 1 mm2. The sensitivity of the system is 156 mV/mm at a frequency bandwidth of 0-2 kHz. Assessment of the laser displacement technique was carried out during 6 dog experiments on the closed chest, on the exposed heart, on blood vessels and also on the chest wall of 5 normal subjects. Displacement of the chest wall at the apical site ranges between 0.3-0.8 mm and of the exposed heart between 3-10 mm.
Rotation Invariant Real-time Face Detection and Recognition System (2001)

In this report, a face recognition system that is capable of detecting and recognizing frontal and rotated faces was developed. Two face recognition methods focusing on the aspect of pose invariance are presented and evaluated - the whole face approach and the component-based approach. The main challenge of this project is to develop a system that is able to identify faces under different viewing angles in realtime. The development of such a system will enhance the capability and robustness of current face recognition technology. The whole-face approach recognizes faces by classifying a single feature vector consisting of the gray values of the whole face image. The component-based approach first locates the facial components and extracts them. These components are normalized and combined into a single feature vector for classification. The Support Vector Machine (SVM) is used as the classifier for both approaches. Extensive tests with respect to the robustness against pose changes are performed on a database that includes faces rotated up to about 40 degrees in depth. The component-based approach clearly outperforms the whole-face approach on all tests. Although this approach isproven to be more reliable, it is still too slow for real-time applications. That is the reason why a real-time face recognition system using the whole-face approach is implemented to recognize people in color video sequences.

An Improved Periodic Acid Fuchsin Sulfite Staining Method for Evaluation of Glycoproteins (1958)

Abstract Modification of the Köiw and Grönwall procedure for the staining of glycoproteins separated by paper electrophoresis has adapted this method to papers of the Whatman 3MM class, with achievement of results comparable to those reported by direct chemical determination of hexose in the individual protein fractions. Preliminary concentration of specimen fluids was achieved by ultrafiltration through collodion sacks. A preliminary wash of the oven-dried paper strips with 95 per cent ethanol was found essential to clear the paper of buffer salts and insure that the pH in the oxidation procedure remained in the 3.0-3.5 range. Close control of the reagent composition and timing of each step were found necessary. Inclusion of 40 per cent ethanol in the oxidation bath and immersion of dry strips were required to insure rapid penetration of the periodic acid. Control of the oxidation procedure at 20 ± 0.5° for 12 minutes was of prime necessity to maintain a low background color. Also, the concentrations of hydrochloric acid in the dye bath and in the wash solutions were found to affect the quality of the final stain. The ethanol wash served to remove residual sulfite and hydrochloric acid and stabilize the color. The new method has been applied to the analysis of several body fluids of normal persons and patients with certain disease entities, and satisfactory glycoprotein distribution patterns have been obtained.
Using RepeatMasker to Identify Repetitive Elements in Genomic Sequences (2009)

RepeatMasker is a popular software tool widely used in computational genomics to identify, classify, and mask repetitive elements, including low-complexity sequences and interspersed repeats. RepeatMasker searches for repetitive sequence by aligning the input genome sequence against a library of known repeats, such as Repbase. Here, we describe two Basic Protocols that provide detailed guidelines on how to use RepeatMasker, either via the Web interface or command-line Unix/Linux system, to analyze repetitive elements in genomic sequences. Sequence comparisons in RepeatMasker are usually performed by the alignment program cross_match, which requires significant processing time for larger sequences. An Alternate Protocol describes how to reduce the processing time using an alternative alignment program, such as WU-BLAST. Further, the advantages, limitations, and known bugs of the software are discussed. Finally, guidelines for understanding the results are provided.
Comparison shopping for a gradient-corrected density functional (1996)

Gradient corrections to the local spin density (LSD) approximation for the exchange-correlation energy are making density functional theory as useful in quantum chemistry as it is in solid-state physics. But which of the many gradient-corrected density functionals should be preferred a priori? We make a graphical comparison of the gradient dependencies of some popular approximations, discussing the exact formal conditions which each obeys and identifying which conditions seem most important. For the exchange energy, there is little formal or practical reason to choose among the Perdew-Wang 86, Becke 88, or Perdew-Wang 91 functionals. But, for the correlation energy, the best formal properties are displayed by the nonempirical PW91 correlation functional. Furthermore, the real-space foundation of PW91 yields an insight into the character of the gradient expansion which suggests that PW91 should work especially well for solids. Indeed, while improving dissociation energies over LSD, PW91 remains the most “local” of the gradient-corrected exchange-correlation functionals and, thus, the least likely to overcorrect the subtle errors of LSD for solids. To show that our analysis of spin-unpolarized functionals is sufficient, we also compute spin-polarization energies for atoms, finding PW91 values only slightly more negative than LSD values. © 1996 John Wiley & Sons, Inc.

A Magnetic Resonance Imaging Study of Planum Temporale Asymmetry in Men With Developmental Dyslexia (1997)

These results challenge the notion that anomalous asymmetry of the PT is strongly associated with developmental dyslexia. Given the heterogeneity of the dyslexic population, some subgroup of dyslexic individuals (i.e., those with developmental language disorders) may show unusual symmetry or reversed asymmetry in this region. However, anomalous asymmetry of the planum did not contribute to functional abnormalities demonstrated in these patients by positron emission tomography.
Measurement of the Noise Spectrum Using a Multiple-Pulse Sequence (2011)

A method is proposed for obtaining the spectrum for noise that causes the phase decoherence of a qubit directly from experimentally available data. The method is based on a simple relationship between the spectrum and the coherence time of the qubit in the presence of a π pulse sequence. The relationship is found to hold for every system of a qubit interacting with the classical-noise, bosonic, and spin baths.
An automated system for rapid evaluation of high-density electrode arrays in neural prostheses (2011)

The success of high-density electrode arrays for use in neural prostheses depends on efficient impedance monitoring and fault detection. Conventional methods of impedance testing and fault detection are time consuming and not always suited for in vivo assessment of high-density electrode arrays. Additionally, the ability to evaluate impedances and faults such as open and short circuits, both in vitro and in vivo, are important to ensure safe and effective stimulation. In this work we describe an automated system for the rapid evaluation of high-density electrode arrays. The system uses a current pulse similar to that used to stimulate neural tissue and measures the voltage across the electrode in order to calculate the impedance. The switching of the system was validated by emulating a high-density electrode array using light-emitting diodes and a resistor-capacitor network. The system was tested in vitro and in vivo using a range of commercially available and in-house developed electrode arrays. The system accurately identified faults in an 84-electrode array in less than 20 s and reliably measured impedances up to 110 kΩ using a 200 µA, 250 µs per phase current pulse. This system has direct application for screening high-density electrode arrays in both clinical and experimental settings.

Multiple myeloma related cells in patients undergoing autologous peripheral blood stem cell transplantation (1999)

A high incidence of oligoclonal serum M-components is observed in multiple myeloma (MM) patients treated with autologous stem cell transplantation (ASCT). To determine whether these M-components are produced by myeloma clonally related cells or caused by an aberrant B-cell regeneration we analysed by semi-nested ASO-RT-PCR and DNA sequencing the immunoglobulin (Ig) variable genes (VH) obtained from bone marrow samples obtained before and after transplantation and peripheral blood stem cell (PBSC) samples from seven patients. Myeloma clonally related cells are identifiable by the expression of variant Ig heavy chain isotypes and were detected in two patients at presentation. No myeloma clonally related cells were found in post-transplantation samples (n = 7) in spite of the appearance of new serum M-components. However, in two cases we amplified sequences from post-transplantation bone marrow cells that were able to bind to the B-cell clone-specific CDR3 oligonucleotides but showed no further similarity regarding the VDJ rearrangement. These data indicate that serum oligoclonality post-transplantation is not caused by myeloma clonally related B cells but rather by the regenerating B-cell compartment.
Elastic and thermoelastic constants of nepheline (1975)

The single-crystal elastic constants, their temperature coefficients, and the thermal expansion coefficients of natrual nepheline, (KAlSiO4)(NaAlSiO4)3, have been measured. The longitudinal modulus c11 and the shear modulus c66 have positive temperature coefficients. Since this implies the existence of a wide range of directions with a zero temperature coefficient of the ultrasonic travel time, nepheline may be a suitable substrate for ultrasonic surface-wave signal processing devices.
Influence of Interleukin-3 and Other Growth Factors on α4β1 Integrin-Mediated Adhesion and Migration of Human Hematopoietic Progenitor Cells (1997)

The mechanisms by which hematopoietic progenitor cells are normally anchored in stromal niches and yet can be mobilized by specific growth factors are poorly understood. It is likely, however, that integrins and their extracellular matrix (ECM) ligands play a key role in this process, and recent evidence suggests that integrin function is modulated by signals originating from activated growth factor receptors. We have now examined this further by studying the role of growth factors on alpha4beta1 integrin-mediated adhesion of human CD34+ hematopoietic progenitor cells to specific recombinant fibronectin fragments coated onto tissue culture dishes. Cells were prepared from cord blood and peripheral blood harvests. During a 30-minute adhesion assay a mean of 74% of CD34 cells attached to the so-called H120 fragment of fibronectin, which contains the strongest alpha4beta1 integrin-binding sequence. The level of cell adhesion was significantly reduced by low concentrations of interleukin-3 (IL-3) (2.5 to 10 ng/mL), whereas stem cell factor (SCF) and granulocyte colony-stimulating factor (G-CSF) at these concentrations did not affect adherence of the cells. Migratory behavior of CD34 cells was examined using fibronectin fragments adsorbed onto a Transwell filter. The H120 fragment supported much higher levels of cell migration than the H0 fragment of fibronectin, which contains a weak alpha4beta1 integrin binding sequence. Over a 16-hour assay, migration of peripheral blood progenitor cells was increased slightly by SCF and by G-CSF. However, a marked stimulation was observed with IL-3, which significantly increased migration. Similar effects were noted with cord blood cells, although a small proportion of cells were able to migrate in the absence of growth factors. These results indicate that there is a highly selective and functional link between the alpha4beta1 integrin and IL-3/IL-3-receptor that could affect the position of stem and progenitor cells in the marrow stroma and influence their growth and development.
Cyclooxygenase-2 inhibitor induces apoptosis and enhances cytotoxicity of various anticancer agents in non-small cell lung cancer cell lines. (2000)

In recent years, a combination of two demographic phenomena, an increase in the number of older people in the population and an increase in the incidence of lung cancer with age, has made it mandatory to develop therapeutic modalities with less toxicity for the treatment of inoperable elderly patients with lung cancer. Our study shows that a cyclooxygenase (COX)-2 inhibitor, nimesulide, can inhibit proliferation of non-small cell lung cancer cell lines in vitro in a dose-dependent manner, in part by inducing apoptosis even at clinically achievable low concentrations. Our observations also suggest that the responsiveness of non-small cell lung cancer to COX-2 inhibitors does not require the presence of wild-type p53, but may be influenced by the degree of COX-2 expression. In addition, we found that nimesulide, when used in combination at clinically achievable concentrations, reduced the IC50 values of various anticancer agents by up to 77%, although the level of reduction varied considerably. Because our previous studies have indicated a significantly increased COX-2 expression in up to 70% of adenocarcinoma cases, the present findings are of great clinical interest. In conjunction with the recent development of next generation, highly selective COX-2 inhibitors, they can be expected to lead to even greater efficacy of their use as adjuncts to various anticancer agents for the treatment of high-risk patients without compromising their quality of life.
Pseudohypoaldosteronism in Eight Families: Different Forms of Inheritance Are Evidence for Various Genetic Defects (1990)

Pseudohypoaldosteronism is a rare hereditary disorder presenting in early infancy with renal salt loss leading to hyponatremia and hyperkalemia despite high levels of plasma aldosterone. The patients are insensitive to mineralocorticoids; however, sodium supplementation is able to correct electrolyte abnormalities. Absent or greatly diminished type I aldosterone receptors in peripheral mononuclear leucocytes have been recently demonstrated and explain the lack of response to mineralocorticoids. We have studied the mode of inheritance in eight families with a total of nine patients. There was evidence for an autosomal recessive form of inheritance in four families, while the other four families appeared to have an autosomal dominant mode of transmission. In three families the autosomal recessive form was characterized by normal receptor as well as hormone data in both parents, while in one family receptor levels in both parents were greatly reduced, but hormone levels were normal. In the four families with an autosomal dominant mode of transmission there was always one parent with reduced receptor binding in peripheral mononuclear leucocytes and elevated serum hormone levels. These parents were entirely asymptomatic. In an extended family we were able to study an aunt and her newborn daughter, who were both also biochemically affected but clinically asymptomatic. It, therefore, appears that this dual pattern of genetic transmission may indicate differing genetic defects which cause the same clinical picture of pseudohypoaldosteronism.

Combined inhibition of Notch and JAK/STAT is superior to monotherapies and impairs pancreatic cancer progression (2013)

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease with a high rate of metastasis. Recent studies have indicated that Notch and janus kinase 2 (JAK2)/signal transducers and activators of transcription 3 (STAT3) signaling pathways are both important for the initiation and progression of PDAC. The purpose of this study was to determine the outcome of targeting these two tumor signaling pathways simultaneously both in vitro and in vivo. We assessed the combinational effects of the γ-secretase inhibitor IX (GSI IX) and JAK2 inhibitor (AG-490) on growth and epithelial plasticity of human pancreatic cancer cell lines, and in a genetically engineered mouse model (Pdx1-Cre, LSL-KrasG12D, p53(lox/+)) of PDAC. Dual treatment with GSI IX and AG-490 significantly impaired cell proliferation, migration, invasion, soft agar growth and apoptosis when compared with monotherapies. Most importantly, combinational treatment significantly attenuates tumor progression in vivo and suppresses conversion from acinar-ductal-metaplasia to PDAC. Our results suggest that targeting Notch and JAK2/STAT3 signaling pathways simultaneously is superior to single inhibitions, supporting combined treatment by GSI IX and AG-490 as a potential therapeutic approach for PDAC. However, the study design limits the direct transfer into the clinic and the impact of dual treatment in patients with PDAC remains still to be determined.

LOCKING DOWN LOG FILES: ENHANCING NETWORK SECURITY BY PROTECTING LOG FILES (2006)

Network security is one of the major issues facing IS today. Securing a network from unauthorized intrusion and detecting unauthorized intrusion are vitally important to ensure that information on the network is free from malicious corruption. Preventing unauthorized access to a network is not always possible. Consequently, the ability to detect a network intrusion is of paramount importance. Log files are one of the means used by system administrators to detect intrusions. However, experienced hackers will often erase the log files. While this proves that network security has been penetrated, it leaves no details on how the hacker entered the system or what he accomplished. Even worse, the experienced hacker can replace the log files with a file showing normal network traffic flows. In this case, it is impossible to detect network intrusion using the log files. Therefore, the log files must be protected to be of any use in network security. This paper will discuss the best practices to use to secure the network system logs. The different methods will range from the least secure to the most secure, often depending on the number of safeguards being employed. These safeguards have been taken from academic research, current business implementations, and our own research.
