The Diabetogenic Activity of Fragments of Human Growth Hormone in Obese (<i>ob/ob</i>) Mice (1978)

The genetically obese (ob/ob) mouse was used to investigate the effects of highly purified human growth hormone (hGH), reduced and S-carbamidomethylated hGH (RCAM-hGH), plasmin-digested RCAM-hGH (PD-RCAM-hGH), and peptide fragments isolated from the plasmin digests of RCAM-hGH on fasting blood glucose concentration and glucose tolerance. Mice treated for three days with hGH exhibited both increased fasting blood glucose concentrations and aggravated intolerance to administered glucose. Similar changes in the fasting blood glucose concentration and glucose tolerance were observed after treatment of mice with RCAM-hGH and PD-RCAM-hGH. Moreover, two noncovalent complexes of peptides of RCAM-hGH, one consisting of residues 1-134 bound to 141-191 (Dal) and the other consisting of almost equal amounts of 1-134 and 42-134 bound to 141-191 (Dc2), appeared to retain the full activity of the native hormone in that they increased fasting blood glucose concentrations and aggravated glucose intolerance in the ob/ob mice. A peptide consisting of residues 95-134 of RCAM-hGH appeared to retain some diabetogenic activity, while a peptide consisting of residues 20-41 was devoid of activity. Tolerance tests performed six hours after a single injection of either hGH or fraction Dal indicated that this time interval was not sufficient to elicit the diabetogenic response. Thus, these studies indicate that neither intact disulfide bridges nor intact primary amino acid sequence of the hGH molecule are required for the expression of its diabetogenic activity.
Mean field approximation using compound Gauss-Markov random field for edge detection and image restoration (2002)

A composed Gauss-Markov random field (CGMRF) model is used with mean field approximation for edge detection and image restoration. A set of iterative equations is presented for the mean values of the intensity field and both horizontal and vertical line processes. It is shown that if the CGMRF is isotropic, the same equations as those of Geiger and Girosi (1989) are obtained. How the proposed method is related to the graduated nonconvexity technique using CGMRF is shown. From an implementation point of view, the emphasis is on the use of an optimal step-descent method to get a robust algorithm. Edge detection and image restoration results from a noisy image are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Metabolism of phenylalanine and biosynthesis of styrene in <i>Penicillium camemberti</i> (2007)

The occurrence of styrene in food may be an important aroma defect (celluloid odour), even at very low concentrations (Miltz et al. 1980) causing consumer rejection and is therefore a problem for the food industry. We examined the biosynthetic pathway leading to styrene formation by Penicillium camemberti using labelled compounds. As styrene is strongly hydrophobic and volatile, we first had to develop a continuous extraction process. Using resins XAD2 it was reasonable to suspect phenylalanine (Phe) as the precursor. The addition of Phe marked with 13C on the ring provokes the accumulation of labelled styrene. The enzyme activities involved were also tentatively measured. Styrene appears to be synthesized from phenylalanine by phenylalanine ammonia-lyase activity followed by a decarboxylation catalysed by a cinnamic acid decarboxylase.
High‐Affinity Transport of γ‐Aminobutyric Acid, Glycine, Taurine, L‐Aspartic Acid, and L‐Glutamic Acid in Synaptosomal (P<sub>2</sub>) Tissue: A Kinetic and Substrate Specificity Analysis (1987)

In a cortical P2 fraction, [14C]gamma-aminobutyric acid ([14C]GABA), [14C]glycine, [14C]taurine, and [14C]glutamic and [14C]aspartic acids are transported by four separate high-affinity transport systems with L-glutamic acid and L-aspartic acid transported by a common system. GABA transport in cortical synaptosomal tissue occurs by one high-affinity system, with no second, low-affinity, transport system detectable. Only one high-affinity system is observed for the transport of aspartic/glutamic acids; as with GABA transport, no low-affinity transport is detectable. In the uptake of taurine and glycine (cerebral cortex and pons-medulla-spinal cord) both high- and low-affinity transport processes could be detected. The high-affinity GABA and high-affinity taurine transport classes exhibit some overlap, with the GABA transport system being more specific and having a much higher Vmax value. High-affinity GABA transport exhibits no overlap with either the high-affinity glycine or the high-affinity aspartic/glutamic acid transport class, and in fact they demonstrate somewhat negative correlations in inhibition profiles. The inhibition profiles of high-affinity cortical glycine transport and those of high-affinity cortical taurine and aspartic/glutamic acid transport also show no significant positive relationship. The inhibition profiles of high-affinity glycine transport in the cerebral cortex and in the pons-medulla-spinal cord show a significant positive correlation with each other; however, high-affinity glycine uptake in the pons-medulla-spinal cord is more specific than that in the cerebral cortex. The inhibition profile of high-affinity taurine transport exhibits a nonsignificant negative correlation with that of the aspartic/glutamic acid transport class.
<title>Class of smooth block transforms and applications in image compression</title> (1994)

In this paper, we present the results of image compression using smooth block transforms. It is shown that such smooth block transforms solve the blocking effect problem very well, especially for high compression ratio. We also discuss the quasi-optimal smooth block transform, but it leaves an open question--computation complexity.
Micro–arc Oxidation and Sol–Gel Composite Coatings on Magnesium Alloy (2011)

Protective composite coatings were obtained on a magnesium alloy by micro-arc oxidation (MAO) and sol-gel technique.The cross-section morphologies and composition of the MAO coating and composite coatings were analyzed by scanning electron microscopy(SEM) and energy dispersive X-rays (EDX).The phase structure of the composite coatings was analyzed by X-ray diffractometer(XRD).The corrosion resistance of MAO coating and composite coatings in a 3.5%(mass fraction) NaCI solution was evaluated by potentiodynamic polarisation measures.The results show that SiO_2-ZrO_2 sol can effectively seal the micropores in the MAO coating,and the composite coatings are more compact and have good adhesion.The composite coatings are composed of MgO,MgAl_2O_4,SiO_2 and ZrO_2.The corrosion resistance of the sample with composite coatings is enhanced significantly.
First-Hop Router Selection by Hosts in a Multi-Prefix Network (2016)

This document describes expected IPv6 host behavior in a scenario that has more than one prefix, each allocated by an upstream network that is assumed to implement BCP 38 ingress filtering, when the host has multiple routers to choose from. It also applies to other scenarios such as the usage of stateful firewalls that effectively act as address-based filters. Host behavior in choosing a first-hop router may interact with source address selection in a given implementation. However, the selection of the source address for a packet is done before the first-hop router for that packet is chosen. Given that the network or host is, or appears to be, multihomed with multiple provider-allocated addresses, that the host has elected to use a source address in a given prefix, and that some but not all neighboring routers are advertising that prefix in their Router Advertisement Prefix Information Options, this document specifies to which router a host should present its transmission. It updates RFC 4861.

<title>Optoelectronic integration of quantum well intersubband photodetectors for two-dimensional array fabrication</title> (1996)

We propose and demonstrate the integration of a quantum well intersubband photodetector (QWIP) and a light emitting diode (LED) for making large two-dimensional focal plane arrays for thermal imaging applications. We combine the newly developed long wavelength infrared QWIP technology with the well-established near infrared LED technology both based on GaAs and related epitaxially grown alloys, such as AlGaAs and InGaAs.
Peptones stimulate both the secretion of the incretin hormone glucagon-like peptide 1 and the transcription of the proglucagon gene. (1998)

Truncated glucagon-like peptide (GLP)-1 is a potent incretin. Its synthesis and secretion are modulated by food, but the influence of individual nutrients remains to be established. The hypothesis that protein hydrolysates (peptones) can directly regulate both GLP-1 secretion and proglucagon (PG) gene transcription was tested in this study, ex vivo in the isolated vascularly perfused rat intestine and in vitro in the murine enteroendocrine cell line STC-1. Peptones were albumin egg hydrolysate (AEH) and meat hydrolysate (MH). We demonstrate in these two models that peptones dose-dependently stimulate GLP-1 release, whereas isocaloric quantities of bovine serum albumin or of an amino acid mixture had no stimulatory effect. A strong and rapid increase of PG RNA level was observed in STC-1 cells treated with peptones (14-fold and 7-fold increase after 4 h of incubation with 3% wt/vol MH and AEH, respectively). Peptones also increased the PG RNA level in the colonic PG-expressing cell line GLUTag. In contrast, peptones did not modify the PG RNA level in two pancreatic glucagon-producing cell lines, namely, the RINm5F and INR1G9 cells. The peptone effect in STC-1 cells was completely abolished by blocking transcription before MH treatment. The stability of proglugacon transcripts was not modified by MH treatment, but nascent transcripts were more abundant in STC-1 cells preincubated with MH. Finally, MH treatment strongly stimulated (15-fold stimulation) the transcriptional activity of two PG gene promoter fragments (-1100 and -350 base pair) linked to the CAT reporter gene transiently transfected in STC-1 cells. Overall, peptones evoke an as yet undescribed release of GLP-1 when brought into contact with native intestinal L-cells or with STC-1 enteroendocrine cells. The increased transcription of the glucagon gene in the latter system suggests an important role of protein hydrolysates in the control of not only the secretion but also the synthesis of the incretin hormone.
Investigation of the Use of Mobile Phones While Driving (1999)

The number of mobile phone users in the U.S. has grown from 500,000 in 1985 to 63 million in 1998. This rapid growth has occurred largely without consideration of the mobile phone's suitability for usage while driving. The objective of this report is to summarize existing information on the subject of mobile phone use while driving, in order to provide a concise summary of the issues for the public, researchers, and legislators alike. The report discusses the benefits of mobile phone usage while driving, such as driver safety and time use efficiency, and negative aspects such as its potential for driver distraction resulting in accidents. The report contains information on the demographics of mobile phone use in the U.S., focusing on user demographics and frequency of usage while driving. Findings from literature on the subject of mobile phone use and driving performance are highly variable. In general, it was found that mobile phone use does have an adverse affect on driving performance, but the significance of the distraction is difficult to quantify. Reports found that people that used a mobile phone while driving were anywhere from 34% to 300% more likely to have an accident. With mobile phone use likely to continue to increase in the future, the safety of driving while using a mobile phone will become a very important safety issue. Therefore, it is important to begin to collect better data on the risks associated with using a mobile phone while driving.

Effects of dehydroepiandrosterone in amphetamine-induced schizophrenia models in mice. (2014)

We observed that DHEA reduced locomotor activity and increased catalepsy at both doses, while it had no effect on climbing behavior. We suggest that DHEA displays typical neuroleptic-like effects, and may be used in the treatment of schizophrenia.

Effect of compound D-600 (methoxyverapamil) on gluconeogenesis and on acceleration of the process by α-adrenergic stimuli in rat kidney tubules (1980)

1. Tubule fragments were isolated from renal cortex of fed rats and glucose formation was measured after incubation with 5 mM-sodium lactate. 20 Compound D-600 (10-100 microM) decreased gluconeogenesis from lactate. This inhibition of the process by compound D-600 increased with increasing extracellular Ca2+ concentration, was overridden by noradrenaline and diminished by starvation for 24 h. 3. Inhibition of lactate-supported gluconeogenesis by compound D-600 was not prevented by the alpha 1-adrenoceptor antagonist thymoxamine. 4. Compound D-600 had little effect on gluconeogenesis from 2-oxoglutarate and increased gluconeogenesis from succinate. 5. Compound D-600 opposed stimulation of gluconeogenesis by noradrenaline or oxymetazoline (a selective alpha-adrenoceptor agonist) in a manner suggesting that compound D-600 is an alpha-adrenoceptor blocker. Oxymetazoline was more sensitive than noradrenaline to blockade by both compound D-600 and by the conventional alpha-adrenoceptor antagonist phentolamine. Noradrenaline became more sensitive to blockade by compound D-600 when extracellular Ca2+ was decreased. 6. Compound D-600 did not block stimulation of gluconeogenesis by angiotensin or cyclic AMP.

Purinergic stimulation of ciliary activity (2000)

The mucociliary system is responsible for maintaining the airways clean of inhaled particles and pathogens. This task is performed by ciliated cells that transport the mucus from the lungs to the upper airways. The energy transferred by the cilium to the mucus blanket is proportional to the square of the ciliary beat frequency (CBF), hence CBF has a profound effect on the efficiency of mucociliary clearance and impairment of ciliary activity may lead to severe pathological conditions by jeopardizing mucociliary clearance. Extracellular ATP is one of the most potent activators of ciliary beating. It acts through purinergic receptors located on the cell surface. Ciliary stimulation is achieved by means of elevation in intracellular calcium concentration and activation of protein kinases. This article outlines the mechanism of purinergic ciliary stimulation revealed to date. Drug Dev. Res. 50:550–554, 2000. © 2000 Wiley-Liss, Inc.
AUTOMATIC CONTROL OF ULTRASONIC RAIL-INSPECTION TRANSDUCERS (1979)

In a recent program at Battelle, supported by the Transportation Systems Center and the Federal Railroad Administration, technology was developed for automatically controlling the lateral position of the ultrasonic transducers used in rail-flaw inspection equipment. Several concepts were evaluated, two of which are described in this paper. One of these was a trial and control technique in which an automatic control system would move the transducer a small amount, determine if the change in positions produces an increase or decrease in the signal level, and then move the transducers in the direction that increases the signal level from the ultrasonic transducer. The second concept evaluated was one where two additional receiver-only transducers are added on each side of an existing transducer. This measures an ultrasonic signal that has been transmitted through the web of the rail. The difference in signal levels at these receiver transducers is a continuous indication of the lateral position error of the transducers and is used as the control signal in a feedback control system to position the transducer laterally over the rail. Evaluation of the concepts consisted of experimental measurements and calculations to determine the desired transducers configuration and other system parameters. The continuous type system was selected as being better for the application and several systems were constructed and are currently operating on both government- and railroad-owned vehicles. The preferred concept can be adapted, with minimal design modification, to most rail-inspection systems in use today.
Multifrequency device for measurement of the complex electrical bio-impedance-design and application (2002)

A multifrequency device for measurement of the modulus and phase shift of complex electrical impedance of the biological tissue has been designed. Impedance measurement is based on the tetrapolar current method with the current amplitude of 1 mA. Phase is obtained using of the modified "zero-crossing" method. The device operates in the frequency range from 2 kHz to 200 kHz (in two sub-ranges) with manual and automatic frequency control. The impedance device was used for the measurement of the modulus |Z/sub 0/| and phase shift /spl phi/ of the transthoracic impedance by Kubicek's method in the frequency range of 2 to 200 kHz the mean values of |Z/sub 0/| changes from 30.7 to 20.2 /spl Omega/ and /spl phi/ respectively from 4.9 to 10.4/spl deg/. In the narrower range usually used in impedance cardiography (20-100 kHz) the change of /spl phi/ is 4/spl deg/. This indicates a necessity to establish a standard for the transthoracic impedance measurement in impedance cardiography method and to use only one chosen frequency. The device can be used for bioimpedance spectroscopic measurements, determination of the extracellular fluids, examination of /spl Delta/Z and /spl Delta//spl phi/ due to ventilation or motion of the heart.
Temperature stability of thin film narrow bandpass filters produced by ion-assisted deposition (1994)

Four types of single-cavity thin-film narrow bandpass filters whose FWHM range from 0.5 to 1.1 nm are produced by ion-assisted deposition of alternating TiO2/SiO2 or Ta2O5/SiO2 layers onto eight substrates having differing coefficients of linear expansion, and the temperature stability of their center wavelengths are examined in the 1540-nm wavelength region. For the eight substrates, whose coefficients of linear expansion range from 0 to 142 X 10<SUP>-7</SUP>/ degree(s)C, the temperature stability of the filters ranges from +0.018 to -0.005 nm/ degree(s)C. Calculations based on a newly developed elastic strain model reveal the main reason temperature stability of the center wavelengths exhibits substrate dependency is due to a reduction in film packing density brought about by volumetric distortion of the film, which is caused by stress induced from the substrate.
