UHF frequency selective limiters (2002)

A frequency selective limiter, based on magnetostatic surface wave propagation in a GaScYIG film, is described. Small signal insertion loss was 10 dB and the threshold power level was -25 dBm over the 400 MHz to 800 MHz frequency range. Small signal attenuation and intermodulation products, resulting from the interaction between two signals, are only significant if the signals are less than 10 MHz apart. Similar devices are expected to be used to extend the dynamic range of broadband receivers.
A diploid wheat TILLING resource for wheat functional genomics (2012)

The mutation frequency of a diploid wheat TILLING population was found to be higher than that reported for other diploid grasses. The rate, however, is lower than tetraploid and hexaploid wheat TILLING populations because of the higher tolerance of polyploids to mutations. Unlike polyploid wheat, most mutants in diploid wheat have a phenotype amenable to forward and reverse genetic analysis and establish diploid wheat as an attractive model to study gene function in wheat. We estimate that a TILLING population of 5, 520 will be needed to get a non-sense mutation for every wheat gene of interest with 95% probability.
Synthesis of 5-Nitro-2-furancarbohydrazides and Their cis-Diamminedichloroplatinum Complexes as Bitopic and Irreversible Human Thioredoxin Reductase Inhibitors (2005)

The human selenoprotein thioredoxin reductase is involved in antioxidant defense and DNA synthesis. As increased thioredoxin reductase levels are associated with drug sensitivity to cisplatin and drug resistance in tumor cells, this enzyme represents a promising target for the development of cytostatic agents. To optimize the potential of the widely used cisplatin to inhibit the human thioredoxin reductase and therefore to overcome cisplatin resistance, we developed and synthesized four cis-diamminedichloroplatinum complexes of the lead 5-nitro-2-furancarbohydrazide 8 selected from high-throughput screening. Detailed kinetics revealed that the isolated fragments, 5-nitro-2-furancarbohydrazide and cisplatin itself, bind with micromolar affinities at two different subsites of the human enzyme. By tethering both fragments four nitrofuran-based cis-diamminedichloroplatinum complexes 13a-c and 20 were synthesized and identified as bi-ligand irreversible inhibitors of the human enzyme with nanomolar affinities. Studies with mutant enzymes clearly demonstrate the penultimate selenocysteine residue as the prime target of the synthesized cis-diamminedichloroplatinum complexes.
Epidemiology of hyperuricemia and gout. (2005)

Gout is an increasingly common medical problem. The traditional risk factors of male sex and high red meat or alcohol consumption have been joined by a wave of newer risk factors, such as increased longevity, the metabolic syndrome (hypertension, diabetes, dyslipidemia, truncal obesity, increased cardiovascular disease risk), use of diuretics, low-dose aspirin, or cyclosporine, and end-stage renal disease. Atypical presentations of gout in the elderly can mimic osteoarthritis and rheumatoid arthritis. There is a resurgence of interest in hyperuricemia as an independent and potentially modifiable cardiovascular risk factor. The pharmacologic management of gout in general practice suffers from a number of quality-control issues. This article reviews these and other new epidemiologic data on this ancient disease.

Pharmacology of vertigo/nystagmus/oscillopsia (2005)

There have been several new developments in the treatment of nystagmus and vertigo over the last 2 years. These include potassium channel blockers for the treatment of downbeat nystagmus, early cortisone treatment to improve recovery of the labyrinth function in vestibular neuritis, and intratympanic gentamicin treatment for Meniere's disease. Other pharmacological treatment options are baclofen for periodic alternating nystagmus, gabapentin and memantine for acquired pendular nystagmus, and carbamazepine for superior oblique myokymia.

3-Acetylpyridine Produces Age-Dependent Excitotoxic Lesions in Rat Striatum (1994)

The effects of 3-acetylpyridine (3-AP) were studied in rat striatum. Striatal injections of 3-AP produced dose-dependent lesions. The lesion size was significantly increased in 4- and 12-month-old rats compared to 1-month-old rats. Coinjection of the competitive N-methyl-D-aspartate (NMDA) antagonist 2-amino-5-phosphonovaleric acid (APV) or systemic administration of the noncompetitive NMDA antagonist MK-801, the competitive NMDA antagonist LY274614, or the glutamate release inhibitor lamotrigine partially but significantly attenuated striatal lesion volume. Consistent with an NMDA receptor-mediated excitotoxic effect, histologic studies showed that 3-AP lesions result in relative sparing of NADPH-diaphorase neurons. Using freeze clamp, 3-AP resulted in a marked depletion of ATP. Two-dimensional water-suppressed proton chemical shift magnetic resonance imaging showed a striatal depletion of the neuronal marker N-acetylaspartate but no focal increase in lactate during the first 3 h after intrastriatal 3-AP injections. Pretreatment with fructose-1,6-biphosphate attenuated the lesion volume significantly, which may be due to its ability to serve as a substrate for glycolytic metabolism, with resulting ATP production. The results of the present studies support the hypothesis that 3-AP produces an impairment of energy metabolism due to its substitution for niacinamide in the formation of NAD(P). Furthermore, 3-AP toxicity may involve a secondary excitotoxic mechanism mediated by NMDA receptors.

ÉTICA, SOCIEDAD Y EDUCACIÓN (PAG. 61-70) (2016)

El ensayo propone algunas reflexiones sobre la relacion organica y contingente entre el desenvolvimiento moral de la sociedad, la sociedad misma y la educacion; en cierto modo como un reflejo teorico reactivo de lo que viene sucediendo facticamente en la sociedad peruana convulsionada por hechos de corrupcion y de diferente factura etico-moral que estan colocando contra las cuerdas a la politica y la gobernabilidad del pais. En esta relacion se parte de establecer las caracteristicas mas sobresalientes de lo que denominados como problematica moral y “crisis moral”, para luego establecer su articulacion compleja con la formacion social vigente y desprender de ello las posibilidades moralmente regeneratorias que tendria la educacion y cuales serian las condiciones globales y sistemicas para ello; apelando a una interpretacion critica y problematizadora de la tematica.Palabras clave: Etica, moral, crisis de valores, sociedad fragmentada, educacion.
Atelier Hands-On Training (2021)

This hands-on workshop explores the tool Atelier that was developed to support feedback in programming tutorials. Our teaching philosophy for programming is based on a tinkering approach, that is characterised by playful exploration, driven by curiosity. Students define from the start their own assignments, given only a set of ingredients to use. The role of a teacher is to provide starting points, explain the first steps to take, and to get students unstuck when necessary. This approach puts students in a very active position but is also very feedback intensive.To support giving feedback and to reduce inconsistencies in feedback given by teaching assistants (TAs), we developed a tool, Atelier, that allows to give comments on code and share this with the respective student, and also with TAs and teachers.The hands-on activity will start with an introduction, followed by an online tutorial lecture with some simple programming assignments. Participants will take the role of students as well as TAs and use Atelier to give and receive feedback. After two rounds of programming exercises, we will evaluate the tool with the participants and discuss its use and place in programming education.
Impaired Increase of Plasma Abscisic Acid in Response to Oral Glucose Load in Type 2 Diabetes and in Gestational Diabetes (2015)

The plant hormone abscisic acid (ABA) is present and active in humans, regulating glucose homeostasis. In normal glucose tolerant (NGT) human subjects, plasma ABA (ABAp) increases 5-fold after an oral glucose load. The aim of this study was to assess the effect of an oral glucose load on ABAp in type 2 diabetes (T2D) subjects. We chose two sub-groups of patients who underwent an oral glucose load for diagnostic purposes: i) 9 treatment-naive T2D subjects, and ii) 9 pregnant women with gestational diabetes (GDM), who underwent the glucose load before and 8-12 weeks after childbirth. Each group was compared with matched NGT controls. The increase of ABAp in response to glucose was found to be abrogated in T2D patients compared to NGT controls. A similar result was observed in the women with GDM compared to pregnant NGT controls; 8-12 weeks after childbirth, however, fasting ABAp and ABAp response to glucose were restored to normal in the GDM subjects, along with glucose tolerance. We also retrospectively compared fasting ABAp before and after bilio-pancreatic diversion (BPD) in obese, but not diabetic subjects, and in obese T2D patients, in which BPD resulted in the resolution of diabetes. Compared to pre-BPD values, basal ABAp significantly increased 1 month after BPD in T2D as well as in NGT subjects, in parallel with a reduction of fasting plasma glucose. These results indicate an impaired hyperglycemia-induced ABAp increase in T2D and in GDM and suggest a beneficial effect of elevated ABAp on glycemic control.
Making the Most of Parameter Estimation: Terpolymerization Troubleshooting Tips (2019)

Multi-component polymers can provide many advantages over their homopolymer counterparts. Terpolymers are formed from the combination of three unique monomers, thus creating a new material that will exhibit desirable properties based on all three of the original comonomers. To ensure that all three comonomers are incorporated (and to understand and/or predict the degree of incorporation of each comonomer), accurate reactivity ratios are vital. In this study, five terpolymerization studies from the literature are revisited and the ‘ternary’ reactivity ratios are re-estimated. Some recent studies have shown that binary reactivity ratios (that is, from the related copolymer systems) do not always apply to ternary systems. In other reports, binary reactivity ratios are in good agreement with terpolymer data. This investigation allows for the comparison between previously determined binary reactivity ratios and newly estimated ‘ternary’ reactivity ratios for several systems. In some of the case studies presented herein, reactivity ratio estimation directly from terpolymerization data is limited by composition restrictions or ill-conditioned systems. In other cases, we observe similar or improved prediction performance (for ternary systems) when ‘ternary’ reactivity ratios are estimated directly from terpolymerization data (compared to the traditionally used binary reactivity ratios). In order to demonstrate the advantages and challenges associated with ‘ternary’ reactivity ratio estimation, five case studies are presented (with examples and counter-examples) and troubleshooting suggestions are provided to inform future work.

Treatment of myasthenia gravis with anti‐CD4 antibody (1994)

We treated a patient with severe myasthenia gravis with a chimeric (murine/human) anti-CD4 monoclonal antibody (cM-T412) for 7 days and followed the therapeutic effect by standardized muscle function tests, single-fiber electromyography, and immunologic examinations of disease-specific B- and T-cell functions. Clinical and electrophysiologic improvement began within 4 days, lasted for 3 months, and was maximal between days 16 and 58. The CD4+ lymphocytes decreased to a minimum of 80 cells per microliters of peripheral blood, recovered slowly during the first year of follow-up, and did not correlate with changes in disease severity. T-cell stimulation by human acetylcholine receptor was abolished by the treatment but became detectable at the time of worsening of symptoms. The concentration of acetylcholine receptor antibodies in serum was not decreased by the treatment. The results suggest that anti-CD4 antibody administration could be effective in the treatment of severe myasthenia gravis and indicate that acetylcholine receptor-specific T lymphocytes might contribute to the disturbed neuromuscular transmission in the disease.
Pseudoxanthoma elasticum with prominent arterial calcifications evoking CD73 deficiency (2019)

Pseudoxanthoma elasticum (PXE) is a rare disorder characterized by skin, eye, and cardiovascular lesions due to ectopic mineralization and fragmentation of elastic fibers of connective tissues. We present an atypical case of PXE with diffuse vascular calcification and negligible skin and eye lesions. The patient was a 37-year-old man suffering from severe bilateral arterial calcifications in superficial femoral and posterior tibial arteries. Eye fundoscopy and skin examination were first considered normal. This phenotype suggested first the diagnosis of Arterial Calcification due to Deficiency of CD73 (ACDC) characterized by mutations in <i>NT5E</i> gene. However, we found two variants in <i>ABCC6</i> gene, and no variant in NT5E. Skin reexamination revealed few lateral skin papules confined to the scalp. Phenotypic overlap was described in vascular calcification disorders, between GACI and PXE phenotypes, and we discuss here expansion of this overlap, including ACDC phenotype. Identification of these expanding and overlapping phenotypes was enabled by genetic screening of the corresponding genes, in a systematic approach. We propose to create a calcification next generation sequencing (NGS) panel with <i>NT5E, GGCX, ENPP1</i>, and <i>ABCC6</i> genes to improve the molecular diagnosis of vascular calcification.

Differential regulation of interleukin 4 and interleukin 5 gene expression: a comparison of T-cell gene induction by anti-CD3 antibody or by exogenous lymphokines. (1990)

Murine T helper type 2 clones were stimulated with immobilized anti-CD3 antibody or with recombinant lymphokines to compare the expression of T-cell activation genes induced by these stimuli. Immobilized anti-CD3 antibody, recombinant interleukin 2 (IL-2), and recombinant interleukin 4 (IL-4) all induced proliferation of the T helper type 2 clones 10-5-17 and D10. Proliferation of these clones induced by anti-CD3 antibody was completely inhibited by cyclosporine A, whereas cyclosporine A had little effect on proliferation induced by recombinant IL-2 or recombinant IL-4. Both immobilized anti-CD3 antibody, and recombinant IL-2 induced the expression of the protooncogenes c-myc and c-myb. Immobilized anti-CD3 antibody also induced expression of the lymphokine genes IL-4, interleukin 5 (IL-5), and granulocyte-macrophage colony-stimulating factor. In contrast, recombinant IL-2 induced IL-5 mRNA expression but did not induce detectable expression of IL-4 or granulocyte-macrophage colony-stimulating factor mRNA. Likewise, recombinant IL-4 induced expression of IL-5 but not IL-4 mRNA. Thus, the IL-4 and IL-5 genes appear to be differentially regulated after stimulation with recombinant lymphokines. Effects of cyclosporine A and the protein synthesis inhibitors cycloheximide and anisomycin on IL-4 and IL-5 gene expression suggest that these genes are activated by different pathways after anti-CD3 stimulation. Cyclosporine A completely inhibited anti-CD3-induced expression of IL-4 mRNA but not of IL-5 mRNA, and protein-synthesis inhibitors completely inhibited induction of IL-5 mRNA but not of IL-4 mRNA. Together, our data show that T-cell receptor-mediated and lymphokine receptor-mediated signals induce different patterns of lymphokine gene expression and provide strong evidence that the IL-4 and IL-5 genes are differently regulated.
Integrated Disposal Facility FY2010 Glass Testing Summary Report (2010)

Pacific Northwest National Laboratory was contracted by Washington River Protection Solutions, LLC to provide the technical basis for estimating radionuclide release from the engineered portion of the disposal facility (e.g., source term). Vitrifying the low-activity waste at Hanford is expected to generate over 1.6 × 105 m3 of glass (Puigh 1999). The volume of immobilized low-activity waste (ILAW) at Hanford is the largest in the DOE complex and is one of the largest inventories (approximately 0.89 × 1018 Bq total activity) of long-lived radionuclides, principally 99Tc (t1/2 = 2.1 × 105), planned for disposal in a low-level waste (LLW) facility. Before the ILAW can be disposed, DOE must conduct a performance assessement (PA) for the Integrated Disposal Facility (IDF) that describes the long-term impacts of the disposal facility on public health and environmental resources. As part of the ILAW glass testing program PNNL is implementing a strategy, consisting of experimentation and modeling, in order to provide the technical basis for estimating radionuclide release from the glass waste form in support of future IDF PAs. The purpose of this report is to summarize the progress made in fiscal year (FY) 2010 toward implementing the strategy with the goal of developing an understanding of the long-term corrosion behavior of low-activity waste glasses. The emphasis in FY2010 was the completing an evaluation of the most sensitive kinetic rate law parameters used to predict glass weathering, documented in Bacon and Pierce (2010), and transitioning from the use of the Subsurface Transport Over Reactive Multi-phases to Subsurface Transport Over Multiple Phases computer code for near-field calculations. The FY2010 activities also consisted of developing a Monte Carlo and Geochemical Modeling framework that links glass composition to alteration phase formation by 1) determining the structure of unreacted and reacted glasses for use as input information into Monte Carlo calculations, 2) compiling the solution data and alteration phases identified from accelerated weathering tests conducted with ILAW glass by PNNL and Viteous State Laboratory/Catholic University of America as well as other literature sources for use in geochemical modeling calculations, and 3) conducting several initial calculations on glasses that contain the four major components of ILAW-Al2O3, B2O3, Na2O, and SiO2.
Peak power reduction of flexible OFDM waveforms for cognitive radio (2011)

High peak-to-average power ratio (PAPR) is one of the major issues in practical orthogonal frequency division multiplexing (OFDM) transmissions. Due to high PAPR and power amplifier nonlinearity, it is typical to observe an increase in the out-of-band (OOB) interference caused by the OFDM transmissions and the bit-error rate at the receiver. The dynamic spectrum access system in this demonstration applies PAPR reduction to frequency-agile and bandwidth-adaptive OFDM transmissions, without sending any side information to the receivers. Partial transmission sequences (PTS) are adopted for PAPR reduction to be compatible with the cyclostationary signatures, embedded into OFDM waveforms for frequency acquisition and bandwidth estimation. In addition, by rotating the signal constellation properly, there is no need to send PTS-related side information to the receivers. The demonstration system is built upon the highly flexible Iris software radio platform, which is capable of providing the runtime reconfigurability needed.
ACUTE PANCREATITIS IN FATAL ANICTERIC LEPTOSPIROSIS (2007)

We report a fatal case of anicteric leptospirosis with pancreatitis (acute hyperglycemia and insulin requirement, elevated lipase and amylase levels), pulmonary infiltrates, and refractory shock. In disease-endemic areas, leptospirosis with pancreatitis should be considered in patients with fever and abdominal pain, and serum pancreatic enzymes, blood glucose, and serum electrolytes should be closely monitored.
T-cell Posttransplant Lymphoproliferative Disorder Occurring in a Pediatric Solid-organ Transplant Patient (2004)

Posttransplantation lymphoproliferative disorder (PTLD) is a serious complication seen in transplant patients as a consequence of immunosuppressant therapy. Most cases are of B-cell origin and are commonly associated with Epstein-Barr virus (EBV) infection. T-cell PTLDs are rare and only 13 pediatric T-cell PTLDs with clinicopathologic correlation have been reported previously. We present the histologic, immunophenotypic, and molecular features of a monomorphic PTLD (T-cell lymphoma) identified in a pediatric patient following orthotopic liver transplantation. The lymphoma was identified in the ileum, rectum, and mesenteric lymph nodes. In situ hybridization revealed numerous EBER-1-positive tumor cells. A current review of the literature is also discussed. Of the 14 cases of pediatric T-cell PTLD reported in the literature, only 3 (21.4%) are described as being EBV positive. Most of the reported PTLDs are monoclonal, with 9 of 11 cases (82%) showing a clonal T-cell population by gene rearrangement studies. T-cell PTLD cases appear to have a poor prognosis (11 of 14 patients died of the disease), although patients with involvement of specific anatomic sites may have a better outcome.
Subcellular localization of branched-chain amino acid aminotransferase and lactate dehydrogenase C4 in rat and mouse spermatozoa (1988)

Spermatozoa isolated from rat and mouse epididymes show a relatively high branched-chain amino acid aminotransferase (leucine aminotransferase, EC 2.6.1.6) activity. There is a significant reduction of leucine aminotransferase and of the isoenzyme C4 of lactate dehydrogenase (EC 1.1.1.27) in the gametes during their epididymal transit. Studies of patterns of liberation of the leucine aminotransferase and of the lactate dehydrogenase C4 from intact spermatozoa, treated with increasing concentrations of digitonin, indicate that both enzymes have the same dual subcellular location, i.e. in the cytosol and in the mitochondria.
