Dietary lignans: physiology and potential for cardiovascular disease risk reduction (2010)

The present review of the literature on lignan physiology and lignan intervention and epidemiological studies was conducted to determine if lignans decrease the risks of cardiovascular disease in Western populations. Five intervention studies using flaxseed lignan supplements indicated beneficial associations with C-reactive protein, and a meta-analysis that included these studies also suggested lignans have a lowering effect on plasma total and low-density lipoprotein cholesterol. Three intervention studies using sesamin supplements indicated possible lipid- and blood pressure-lowering associations. Eleven human observational epidemiological studies examined dietary intakes of lignans in relation to cardiovascular disease risk. Five showed decreased risk with either increasing dietary intakes of lignans or increased levels of serum enterolactone (an enterolignan used as a biomarker of lignan intake), five studies were of borderline significance, and one was null. The associations between lignans and decreased risk of cardiovascular disease are promising, but they are yet not well established, perhaps due to low lignan intakes in habitual Western diets. At the higher doses used in intervention studies, associations were more evident.
Gyrotron beam coupling method into corrugated waveguide (2009)

A coupling method of a gyrotron beam into a corrugated waveguide is proposed to achieve high HE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> mode purity in ITER's ECH&CD transmission line. A matching optical unit (MOU) with two phase correcting mirrors is used. Each mirror is mounted on a goniometer stage for angle control. The mode content in the waveguide is measured for several sets of mirror angles to maximize the mode purity. The mode content is deduced using RF field profiles radiated from the waveguide outlet. A demonstrative procedure of the beam coupling achieved 93% of HE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> mode in the transmission power.
Phosphonium-Functionalized Polyethylene: A New Class of Base-Stable Alkaline Anion Exchange Membranes (2012)

A tetrakis(dialkylamino)phosphonium cation was evaluated as a functional group for alkaline anion exchange membranes (AAEMs). The base stability of [P(N(Me)Cy)(4)](+) was directly compared to that of [BnNMe(3)](+) in 1 M NaOD/CD(3)OD. The high base stability of [P(N(Me)Cy)(4)](+) relative to [BnNMe(3)](+) inspired the preparation of AAEM materials composed of phosphonium units attached to polyethylene. The AAEMs (hydroxide conductivity of 22 ± 1 mS cm(-1) at 22 °C) were prepared using ring-opening metathesis polymerization, and their stabilities were evaluated in 15 M KOH at 22 °C and in 1 M KOH at 80 °C.
Plasmon Resonance in Individual Nanogap Electrodes Studied Using Graphene Nanoconstrictions as Photodetectors (2011)

We achieve direct electrical readout of the wavelength and polarization dependence of the plasmon resonance in individual gold nanogap antennas by positioning a graphene nanoconstriction within the gap as a localized photodetector. The polarization sensitivities can be as large as 99%, while the plasmon-induced photocurrent enhancement is 2-100. The plasmon peak frequency, polarization sensitivity, and photocurrent enhancement all vary between devices, indicating the degree to which the plasmon resonance is sensitive to nanometer-scale irregularities.
Productivity of a Horizontal Well (1989)

Summary An equation for calculating the pseudosteady-state flow—i.e., the productivity—of a horizontal well is presented that is easy to use and identical in form to the well-known productivity equation for a vertical well. The equation was extracted from a very complex general solution. Application of the equation requires the determination of two parameters: (1) a geometric factor that accounts for the effect of permeability anisotropy, well location, and the relative dimensions of the drainage volume and (2) the skin caused by restricted entry, which accounts for the effect of well length. The paper gives simple equations for calculating these two parameters. The equation is used to study the effects on well productivity of well length, location, and degree of penetration; vertical and horizontal permeabilities; and the horizontal dimensions of the drainage volume. It is concluded that, though each of these variables has a significant effect, the well length and degree of penetration have the strongest.
Nutritive value of some indigenous plant rhizomes resembling Ginger. (2009)

Rhizomes of certain Ginger like species, viz. Alpinia officinarum Hance, A. galanga Willd., A. zerumbet (Pers.) Burtt & R M Smith (syn. A. speciosa K. Schum.), A. calcarata Rosc. and Kaempferia galanga Linn. have high medicinal value belonging to family Zingiberaceae. These rhizomes have a good nutritive value also (350.9 Cal per 100 g) and are quite rich in protein and carbohydrate, but low in fat. Rhizomes of A. officinarum, A. zerumbet and A. calcarata have high iron content with a moderate and balanced content of carbohydrate, protein, fat and crude fibre. Rhizomes of A. galanga are lowest in fat content but richest in carbohydrate. A. calcarata is lowest in Mn, Ni and K but richest in Ca and Na. Study shows the biologically important metals Cr, Mn, Cu, Zn, Ca and Na to be sufficient in rhizomes of K. galanga. All these studied materials have a moderate to good antimicrobial activity.
Mining Ontological Knowledge from Domain-Specific Text Documents (2006)

Traditional text mining systems employ shallow parsing techniques and focus on concept extraction and taxonomic relation extraction. This paper presents a novel system called CRCTOL for mining rich semantic knowledge in the form of ontology from domain-specific text documents. By using a full text parsing technique and incorporating both statistical and lexico-syntactic methods, the knowledge extracted by our system is more concise and contains a richer semantics compared with alternative systems. We conduct a case study wherein CRCTOL extracts ontological knowledge, specifically key concepts and semantic relations, from a terrorism domain text collection. Quantitative evaluation, by comparing with a state-of-the-art ontology learning system known as text-to-onto, has shown that CRCTOL produces much better precision and recall for both concept and relation extraction, especially from sentences with complex structures.
Liquid Corrosion and High‐Temperature Oxidation Effects on Silicon Carbide/Titanium Diboride Composites (1988)

A silicon carbide composite containing titanium diboride particulate reinforcement was subjected to room‐temperature acidic corrosion in aqua regia solutions for 200 h, and 50% NaOH+50% H 2 O and 10% HF+57% HNO 3 +33% H 2 O solutions for up to 500 h. A small increase in room‐temperature strength was observed after the aqua regia exposure. Separately, this ceramic was oxidized at 1400°C for 24 h and then tested for strength retention at room temperature. Contrary to the observations reported in the literature on similar material, there was no significant room‐temperature strength decrease in this particular composite.
Pressure Curves from the Right Auricle and the Right Ventricle in Chronic Constrictive Pericarditis (1951)

Characteristic patterns of the pressure curves from the right auricle and the right ventricle have been found in chronic constrictive pericarditis by various investigators. It has been uncertain, however, whether or not the findings were pathognomonic, and whether they were reliable pictures of the pressure conditions or artefacts. Consequently the views upon the underlying mechanism have been different too. It is concluded from the studies here presented that the pressure curves are pathognomonic when in their most pronounced form, and that they are not artefacts and thus furnish a proper basis for inferences as to the hemodynamics in chronic constrictive pericarditis.
Reactions of diaminoalkanes with bismaleimides: Synthesis of some unusual polyimides (1984)

Abstract Michael additions of the secondary diamines N , N ′‐dimethyl‐1,6‐hexanediamine ( 14 ) or piperazine to the electrophilic carbon–carbon double bonds of N , N ′‐bismaleimido‐4,4′‐diphenylmethane ( 2 ) or N , N ′‐bismaleimido‐1,8‐octane ( 4 ) afford four unusual, high‐molecular‐weight (η inh = 0.49–2.16 dL/g) polyimides ( 10 – 13 ). The most interesting of these, polymer 12 (the product of 4 and 14 ), is a tough elastomeric resin with a glass transition temperature ( T g ) near 0°C; in contrast, 10, 11, and 13 exhibit T g >86°C. Freshly prepared 12 is soluble and thermoplastic ( 12 is readily compression molded at 110°C), but the bulk polymer crosslinks slowly under ambient laboratory conditions and eventually (48 days) becomes insoluble, while 10, 11, and 13 remain soluble indefinitely. Along with further comparisons of the properties of 10 – 13 , details of the synthesis and characterization of these new polyimides are described. Also discussed are reactions of bismaleimide 2 with 1,6‐diaminohexane, which unlike the formation of linear 10 – 13 , generate crosslinked, insoluble products.
BER of optical communication system using fiber source (2002)

We analyze the bit-error rate (BER) of an optical communication system using the superfluorescent fiber source (SFS). The counting statistics of thermal light give improved performance relative to the Gaussian statistics that predict a BER floor. We consider a spectrum-sliced wavelength-division multiple access (WDMA) system that employs the SFS.
<i>FLT3</i>tyrosine kinase inhibitors in acute myeloid leukemia: clinical implications and limitations (2013)

Internal tandem duplications of the FMS-like tyrosine kinase 3 (FLT3) gene are one of the most frequent gene mutations in acute myeloid leukemia (AML) and are associated with poor clinical outcome. The remission rate is high with intensive chemotherapy, but most patients eventually relapse. During the last decade, FLT3 mutations have emerged as an attractive target for a molecularly specific treatment strategy. Targeting FLT3 receptor tyrosine kinases in AML has shown encouraging results in the treatment of FLT3 mutated AML, but in most patients responses are incomplete and not sustained. Newer, more specific compounds seem to have a higher potency and selectivity against FLT3. During therapy with FLT3 tyrosine kinase inhibitors (TKIs) the induction of acquired resistance has emerged as a clinical problem. Therefore, optimization of the targeted therapy and potential treatment options to overcome resistance is currently the focus of clinical research. In this review we discuss the use and limitations of TKIs as a therapeutic strategy for the treatment of FLT3 mutated AML, including mechanisms of resistance to TKIs as well as possible novel strategies to improve FLT3 inhibitor therapy.
Theoretical Implications of the Spacing Effect 1 (2024)

Interest in the effects on memory of the temporal distribution of study trials goes back to some of the very first memory experiments. Jost (1897) noted a facilitative effect of the spacing of learning trials in Ebbinghaus’s data, and set out to study it systematically. More than sixty years later, Underwood (1961) was compelled by a large body of experimental evidence to conclude that “Facilitation by distributed practice in verbal learning occurs only under a highly specific set of conditions, and the magnitude of the effect when it does occur is relatively small [p. 230] .” Today, with interest focused more on the learning of individual items than on the acquisition of multi-item lists, and with study and test trials for a particular to-be-remembered item routinely separated, the conclusion is quite different. The effect on retention of the spacing of repetitions is large, and the number of different conditions under which it occurs is truly remarkable.
Novel roles for KLF1 in erythropoiesis revealed by mRNA-seq (2012)

KLF1 (formerly known as EKLF) regulates the development of erythroid cells from bi-potent progenitor cells via the transcriptional activation of a diverse set of genes. Mice lacking Klf1 die in utero prior to E15 from severe anemia due to the inadequate expression of genes controlling hemoglobin production, cell membrane and cytoskeletal integrity, and the cell cycle. We have recently described the full repertoire of KLF1 binding sites in vivo by performing KLF1 ChIP-seq in primary erythroid tissue (E14.5 fetal liver). Here we describe the KLF1-dependent erythroid transcriptome by comparing mRNA-seq from Klf1(+/+) and Klf1(-/-) erythroid tissue. This has revealed novel target genes not previously obtainable by traditional microarray technology, and provided novel insights into the function of KLF1 as a transcriptional activator. We define a cis-regulatory module bound by KLF1, GATA1, TAL1, and EP300 that coordinates a core set of erythroid genes. We also describe a novel set of erythroid-specific promoters that drive high-level expression of otherwise ubiquitously expressed genes in erythroid cells. Our study has identified two novel lncRNAs that are dynamically expressed during erythroid differentiation, and discovered a role for KLF1 in directing apoptotic gene expression to drive the terminal stages of erythroid maturation.
Acoustic propagation in the ocean with a porous bottom (1982)

Biot's theory was directly incorporated with the normal mode analysis of acoustic propagation in the ocean with a porous elastic bottom. The complex dispersion relations was obtained in a closed form for the case of a homogeneous ocean with a poro-elastic half-space. The attenuation data from the shallow water experiments in the Mediterranean Sea were compared with the theoretical calculations. The 100-m water/sandy bottom data showed an optional transmission frequency of about 250 Hz. The theoretical analysis using the sediment data revealed that the attenuation of the high-frequency components are mainly due to the seepage of pore water through the sand (the slow compressional wave effect) and the attenuation of the low-frequency components are owing to the energy dissipation of the shear waves by the Coulomb friction in the consolidated sand. As a result, the intermediate frequency components have minimum overall attenuations and result into the optimal transmission frequencies. The agreements between the theory and the experiments are good. [Work supported by NSF.]
Environmental Estrogens Induce Mast Cell Degranulation and Enhance IgE-Mediated Release of Allergic Mediators (2006)

Our findings suggest that estrogenic environmental pollutants might promote allergic diseases by inducing and enhancing mast cell degranulation by physiologic estrogens and exposure to allergens.
Experimental evaluation of phase noise compensation for 60-GHz single carrier systems (2010)

This paper introduces a 60-GHz millimeter-wave experimental system for single-carrier (SC) transmission, and verifies an effectiveness of a SC receiver employing decision-directed phase noise compensation (DD-PNC) by the experimental system. A relatively large phase noise occurs in 60-GHz transceivers based on the silicon technology, and significantly degrades transmission performances in the multi-level QAM. In order to alleviate the performance degradation, the receivers employing DD-PNC for OFDM and SC systems have been proposed, and evaluated only by computer simulations. This paper presents the 60-GHz wireless experimental system which consists of a 60-GHz radio frequency circuit and a baseband signal processing circuit. In addition, the 60-GHz experimental system demonstrates that the SC receiver employing DD-PNC can effectively remove the phase noise, and that the receiver with three iterations can achieve PER = 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−2</sup> at the received SNR = 11.3 dB, when 16QAM with the coding rate of 1/2 is employed and the phase noise is −77 dBc/Hz at 1 MHz offset.
Generating Oocytes and Sperm from Embryonic Stem Cells (2005)

Embryonic stem (ES) cells, derivatives of cells of early mammalian embryos, have turned out to be one of the most powerful tools in developmental and stem cell biology. When injected into embryos, ES cells can contribute to tissues derived from all three germ layers and to the germline. Amazingly, ES cells in culture are able to recapitulate features of embryonic development spontaneously. In addition to previous successes in deriving somatic cell types, recent studies have shown that both mouse and human ES cells can also give rise to primordial germ cells (PGCs) in culture. These mouse germ cells appear to be capable of undergoing meiosis and forming both male and female gametes. Although the full function of these ES-derived germ cells and gametes remains to be demonstrated, these findings open the door for undertaking new types of reproductive studies and novel approaches in regenerative medicine.
Review: research on chronic illness has shifted towards viewing the individual as empowered and a partner in the health management process (1999)

Management of 3-Aminopyridine-2-Carboxaldehyde Thiosemicarbazone-Induced Methemoglobinemia (2012)

The anticancer agent 3-aminopyridine-2-carboxaldehyde thiosemicarbazone is a ribonucleotide reductase inhibitor. It inactivates ribonucleotide reductase by disrupting an iron-stabilized radical in ribonucleotide reductase's small subunits, M2 and M2b (p53R2). Unfortunately, 3-aminopyridine-2-carboxaldehyde thiosemicarbazone also alters iron II (Fe(2+)) in hemoglobin. This creates Fe(3+) methemoglobin that does not deliver oxygen. Fe(2+) in hemoglobin normally auto-oxidizes to inactive Fe(3+) methemoglobin at a rate of nearly 3% per day and this is counterbalanced by a reductase system that normally limits methemoglobin concentrations to less than 1% of hemoglobin. This balance may be perturbed by symptomatic toxicity levels during 3-aminopyridine-2-carboxaldehyde thiosemicarbazone therapy. Indications of 3-aminopyridine-2-carboxaldehyde thiosemicarbazone sequelae attributable to methemoglobinemia include resting dyspnea, headaches and altered cognition. Management of methemoglobinemia includes supplemental oxygen, ascorbate and, most importantly, intravenously administered methylene blue as a therapeutic antidote.
