Pigment composition and processing of blue-grained wheat (1998)

Wheat grain colours range from white, yellow, light-red to dark-red, depending on pigment type and concentration, which are used to distinguish the major market classes of wheat.The pigmentation intensity in a particular wheat species is determined by genetic and environmental factors.Despite the small concentration of pigments in wheat, they have a great influence on the characteristics of its products.These pigments could be desirable or not depending on wheat species and its end-use.Unique genotypes of wheat with blue and purple grains have also been developed for the production of specialty wheat products.The purple pigment is located in the grain pericarp, while blue pigment is found in the aleurone layer (Zeven 1991).Early studies on anthocyanin pigmentation in wheat were conducted by Nillson-Ehle during the second decade of this century.While much information is available on xanthophylls, carotenoids and flavones in wheat, little has been reported on anthocyanins.Anthocyanins are glycosides of polyhydroxy and polymethoxy derivatives of 2phenylbenzopyrylium or flavylium salts.They are widespread in the plant kingdom and impart attractive red and blue colours.The major anthocyanins in the pericarp of purple-grained wheat were found to be cyanidin 3-glucoside and peonidin 3-glucoside with trace amounts of the corresponding rutinosides (Dedio et al. 1972).The present study was carried out to determine pigment composition and end-use quality of blue-grained spring wheat which is adapted to Saskatchewan growing conditions.Blue wheat was also evaluated for its potential in milling, baking and extrusion processes to produce specialty food ingredients and/or products. Wheat GrainsA composite sample of spring blue wheat "Purendo 38" was obtained from selected locations in central Saskatchewan.Konini purple wheat and Katepwa, a common hard red spring wheat, were grown side by side as controls.The grains were ground to pass a 1 mm screen on a Udy Cyclone sample mill (Udy Co., Fort Collins, CO) to produce whole wheat flour (meal).For milling into flour, the grain samples were tempered over an 18-hr period to 14.5% moisture for blue and purple wheats and 15.5% for common wheat.The tempered grain samples were milled
Effects of Short- and Long-Term Soy Protein Feeding on Hepatic Cytochrome P450 Expression in Obese Nonalcoholic Fatty Liver Disease Rat Model (2021)

Obesity can lead to chronic health complications such as nonalcoholic fatty liver disease (NAFLD). NAFLD is characterized by lipid aggregation in the hepatocytes and inflammation of the liver tissue as a consequence that can contribute to the development of cirrhosis and hepatocellular carcinoma (HCC). Previously, we reported that feeding obese Zucker rats with soy protein isolate (SPI) can reduce liver steatosis when compared with a casein (CAS) diet as a control. However, the effects of SPI on cytochrome P450 (CYP) in an obese rat model are less known. In addition, there is a lack of information concerning the consumption of soy protein in adolescents and its effect in reducing the early onset of NAFLD in this group. Our main goal was to understand if the SPI diet had any impact on the hepatic CYP gene expression when compared with the CAS diet. For this purpose, we used the transcriptomic data obtained in a previous study in which liver samples were collected from obese rats after short-term (eight-week) and long-term (16-week) feeding of SPI (<i>n</i> = 8 per group). To analyze this RNAseq data, we used Ingenuity Pathway Analysis (IPA) software. Comparing short- vs long-term feeding revealed an increase in the number of downregulated CYP genes from three at 8 weeks of SPI diet to five at 16 weeks of the same diet (<i>P</i> ≤ 0.05). On the other hand, upregulated CYP gene numbers showed a small increase in the long-term SPI diet compared to the short-term SPI diet, from 14 genes at 8 weeks to 17 genes at 16 weeks (<i>P</i> ≤ 0.05). The observed changes may have an important role in the attenuation of liver steatosis.
Tissue and species distribution of the glutathione pathway transcriptome (2006)

The goal of this study was to compare and contrast the basal gene expression levels of the various enzymes involved in glutathione metabolism among tissues and genders of the rat, mouse and canine. The approach taken was to use Affymetrix GeneChip microarray data for rat, mouse and canine tissues, comparing intensity levels for individual probes between tissues and genders. As was hypothesized, the relative expression in liver, lung, heart, kidney and testis varied from gene to gene, with differences of expression between tissues sometimes greater than a 1000-fold. The pattern of differential expression was usually similar between male and female animals, but varied greatly between the three species. Gstp1 appears to be expressed at high levels in male mouse liver, reasonable levels in canine liver, but very low levels in male rat liver. In all species examined, Gstp1 expression was below detectable levels in testis. Gsta3/Yc2 expression appeared high in rodent liver and female canine liver, but not male canine liver. Finally, Mgst1 and Gpx3 expression appeared to be lower in canine heart and testis than seen in rodents. Given the critical role of the glutathione pathway in the detoxification of many drugs and xenobiotics, the observed differences in basal tissue distribution among mouse, rat and canine has far-reaching implications in comparing responses of these species in safety testing.
Cheaper Private Set Intersection via Differentially Private Leakage (2019)

Abstract In this work we demonstrate that allowing differentially private leakage can significantly improve the concrete performance of secure 2-party computation (2PC) protocols. Specifically, we focus on the private set intersection (PSI) protocol of Rindal and Rosulek (CCS 2017), which is the fastest PSI protocol with security against malicious participants. We show that if differentially private leakage is allowed, the cost of the protocol can be reduced by up to 63%, depending on the desired level of differential privacy. On the technical side, we introduce a security model for differentially-private leakage in malicious-secure 2PC. We also introduce two new and improved mechanisms for “differentially private histogram overestimates,” the main technical challenge for differentially-private PSI.
DELAY OF GERMINATION 1 mediates a conserved coat-dormancy mechanism for the temperature- and gibberellin-dependent control of seed germination (2014)

Seed germination is an important life-cycle transition because it determines subsequent plant survival and reproductive success. To detect optimal spatiotemporal conditions for germination, seeds act as sophisticated environmental sensors integrating information such as ambient temperature. Here we show that the delay of germination 1 (DOG1) gene, known for providing dormancy adaptation to distinct environments, determines the optimal temperature for seed germination. By reciprocal gene-swapping experiments between Brassicaceae species we show that the DOG1-mediated dormancy mechanism is conserved. Biomechanical analyses show that this mechanism regulates the material properties of the endosperm, a seed tissue layer acting as germination barrier to control coat dormancy. We found that DOG1 inhibits the expression of gibberellin (GA)-regulated genes encoding cell-wall remodeling proteins in a temperature-dependent manner. Furthermore we demonstrate that DOG1 causes temperature-dependent alterations in the seed GA metabolism. These alterations in hormone metabolism are brought about by the temperature-dependent differential expression of genes encoding key enzymes of the GA biosynthetic pathway. These effects of DOG1 lead to a temperature-dependent control of endosperm weakening and determine the optimal temperature for germination. The conserved DOG1-mediated coat-dormancy mechanism provides a highly adaptable temperature-sensing mechanism to control the timing of germination.

Transient Absorption Spectroscopy of TlBr Crystals Using Pulsed Electron Beams (2020)

We analyzed the transient absorption properties of TlBr crystals using pulsed electron beams as excitation sources. We observed transient absorption spectra and temporal profiles on the pico-and nanosecond scales and compared the results obtained for TIBr crystals that are empirically appropriate with those that are inappropriate for semiconductor detectors. The results showed negligible differences in properties between the two types of crystal, which indicates that their trap center concentrations were similar. A transient absorption band was observed at approximately 1160 nm on the nanosecond scale, while its short-wavelength tail was observed on the picosecond scale. The absorption band is attributed to the localized holes at Tl + that are stabilized by some defects. In contrast, no absorption band attributable to localized electron centers was observed, indicating that while hole transport is hindered by defects, electron transport is not.
Integrated and differential fiducial cross-section measurements for the vector boson fusion production of the Higgs boson in the H→WW*→eνμν decay channel at 13 TeV with the ATLAS detector (2023)

The vector-boson production cross section for the Higgs boson decay in the H→WW∗→eνμν channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well as integrated in a fiducial phase space. The analysis is performed using the proton-proton collision data collected by the ATLAS detector in Run 2 of the LHC at √s=13 TeV center-of-mass energy, corresponding to an integrated luminosity of 139 fb−1. The different flavor final state is studied by selecting an electron and a muon originating from a pair of W bosons and compatible with the Higgs boson decay. The data are corrected for the effects of detector inefficiency and resolution, and the measurements are compared with different state-of-the-art theoretical predictions. The differential cross sections are used to constrain anomalous interactions described by dimension-six operators in an effective field theory.
Structure of the putative thioesterase protein TTHA1846 fromThermus thermophilusHB8 complexed with coenzyme A and a zinc ion (2009)

TTHA1846 is a conserved hypothetical protein from Thermus thermophilus HB8 with a molecular mass of 15.1 kDa that belongs to the thioesterase superfamily (Pfam 03061). Here, the 1.9 A resolution crystal structure of TTHA1846 from T. thermophilus is reported. The crystal structure is a dimer of dimers. Each subunit adopts the so-called hot-dog fold composed of five antiparallel beta-strands flanked on one side by a rather long alpha-helix and shares structural similarity to a number of thioesterases. Unexpectedly, TTHA1846 binds one metal ion and one ligand per subunit. The ligand density was modelled as coenzyme A (CoA). Its structure was confirmed by MALDI-TOF mass spectrometry and electron-density mapping. X-ray absorption fine-structure (XAFS) measurement of the crystal unambiguously characterized the metal ion as zinc. The zinc ion is tetrahedrally coordinated by the side chains of Asp18, His22 and Glu50 and the CoA thiol group. This is the first structural report of the interaction of CoA with a zinc ion. From structural and database analyses, it was speculated that the zinc ion may play an inhibitory role in the enzymatic activity.
Retinal Toxicity of Intravitreal Melphalan in Albino Rabbits (2018)

Background: Intravitreal melphalan injections have been used for treating retinoblastoma with vitreous seeds. The aim of this study was to evaluate the safety margins for intravitreal melphalan, using clinical observations, electrophysiological testing and morphological observations. Methods: In this experimental study, 18 albino rabbits, were treated with intravitreal injection of 0.1 ml melphalan solution to the right, experimental eye, and were divided into 4 dose groups: 5 μg (N=4); 15 μg (N=4); 30 μg (N=5); 60 μg (N=5). The left, control eye, of each rabbit was injected with 0.1 ml saline. Clinical examination, electroretinography (ERG) and visual evoked potentials (VEP) were conducted at baseline and periodically throughout the 4-week follow-up. The eyes were then enucleated and the retinas were prepared for histology and glial fibrillary acidic protein (GFAP) immunocytochemistry. Results: No clinical, ERG, or histologic damage were found in rabbits treated with 5 μg melphalan. However, expression of glial fibrillary acidic protein was detected in retinal Muller cells of the experimental eyes and not in the control eyes. With all other doses of melphalan, dose-dependent funduscopic changes, ERG amplitude, histological damage and GFAP expression were found. VEP responses were similar between the experimental eyes and control eyes of all rabbits regardless of melphalan dose injected into the eye, indicating no change in retinal output. Conclusions: These findings indicate that intravitreal melphalan dose of 5 μg in rabbits, approximately equivalent to 10 μg in human, appears to be safe, but induce a mild stress to the retina. However, higher doses are toxic, and their utilization should be executed with caution, particularly if visual potential exists.
α-Synuclein Membrane Interactions and Lipid Specificity (2000)

With the discovery of missense mutations (A53T and A30P) in alpha-synuclein (alpha-Syn) in several families with early onset familial Parkinson's disease, alpha-Syn aggregation and fibril formation have been thought to play a role in the pathogenesis of alpha-synucleinopathies, such as Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. As previous reports have suggested that alpha-Syn plays a role in lipid transport and synaptic membrane biogenesis, we investigated whether alpha-Syn binds to a specific lipid ligand using thin layer chromatography overlay and examined the changes in its secondary structure using circular dichroism spectroscopy. alpha-Syn was found to bind to acidic phospholipid vesicles and this binding was significantly augmented by the presence of phosphatidylethanolamine, a neutral phospholipid. We further examined the interaction of alpha-Syn with lipids by in situ atomic force microscopy. The association of soluble wild-type alpha-Syn with planar lipid bilayers resulted in extensive bilayer disruption and the formation of amorphous aggregates and small fibrils. The A53T mutant alpha-Syn disrupted the lipid bilayers in a similar fashion but at a slower rate. These results suggest that alpha-Syn membrane interactions are physiologically important and the lipid composition of the cellular membranes may affect these interactions in vivo.
Machining Phenomena in EDM of Insulating Ceramics with Powder Mixed Oil. (2002)

In this paper we describe the machining characteristics of insulating Si3N4 ceramics by using several kinds of powder mixed oil. With powder mixed oil, the removal rate was improved due to discharge dispersion. However, contrary to expectations, the surface roughness was not sufficiently improved by using only the powder mixed oil, since a long pulse discharge that exceeded the settled pulse duration was generated. This phenomenon is often observed in the case of EDM of a high-resistivity material. In order to obtain a smooth surface, the machining was carried out under limited pulse duration with powder mixed oil so that the long pulse could not be generated. Tests revealed that the removal rate in drilling Si3N4 by EDM was almost the same as that by the grinding process and the surface roughness was reduced to 4μmRy.
Insights on Inter-metal Reliability Assessment of High Voltage Interconnects (2022)

Reliability qualification of HV interconnects is more complicated due to the additional inter-metal impact under high voltage operation. Typically, this is less critical under nominal voltage operation. Unlike intra-metal structure, the film stack, and the bottom physical profile of the inter-metal structure are uneven. This explains the reliability response showing the dependence on metal line width and bias polarity. We show that the E-field distribution is not uniform, with the highest E-field density observed at the bottom corners of the metal line. This corresponds to the uneven bottom metal profile with sharp corners. Hence, for a complete inter-metal TDDB reliability qualification, the impacts from test structure design, process variation, and testing methodology need to be considered.
Electrophysiological evidence for different release mechanism of ATP and NO as inhibitory NANC transmitters in guinea‐pig colon (1994)

1. The effect of the P2-purinoceptor antagonist, suramin, the specific N-type voltage-dependent calcium channel blocker, omega-conotoxin GVIA (omega-CgTx) and the delta-opioid receptor agonist [D-Pen2,D-Pen5] enkephalin (DPDPE) on the apamin-sensitive and apamin-resistant inhibitory junction potentials (i.j.ps) produced by electrical field stimulation (EFS) were investigated by means of a sucrose-gap technique in the circular muscle of the guinea-pig colon. 2. After incubation of muscle strips in either atropine (1 microM), guanethidine (3 microM) and NG-nitro-L-arginine (L-NOARG, 30 microM) or atropine, guanethidine and apamin (0.3 microM), the addition of the NK1 receptor antagonist, SR 140,333 (1 microM) abolished the non-adrenergic, non-cholinergic (NANC) excitatory junction potential (e.j.p.) and unmasked a pure apamin-sensitive i.j.p. (in the presence of L-NOARG) or a pure apamin-resistant i.j.p. (in the presence of apamin). Both types of i.j.p. were abolished by tetrodotoxin. 3. Suramin (30-300 microM) concentration-dependently inhibited the apamin-sensitive i.j.p., while the apamin-resistant i.j.p. was not significantly affected by suramin (up to 300 microM). L-NOARG (30 microM) markedly reduced the apamin-resistant i.j.p. 4. The delta-opioid receptor agonist, DPDPE (0.03-3 microM) concentration-dependently reduced the apamin-sensitive i.j.p., while leaving the apamin-resistant i.j.p. unaffected. Naloxone (1 microM) prevented the i.j.p. inhibition evoked by DPDPE (0.3 microM). 5. omega-CgTx (0.3 microM) markedly reduced the apamin-sensitive but not the apamin-resistant i.j.p. The application of DPDPE (3 MicroM), after development of a steady state inhibitory effect by omega-CgTx, evoked further inhibition of the apamin-sensitive ij.p., similar to the effect produced by DPDPE alone. The L-type calcium channel blocker, nifedipine (1 MicroM) did not significantly affect either the apamin-sensitive or the apamin-resistant ij.ps.6. These findings support the purinergic origin of the fast, apamin-sensitive ij.p. produced by EFS in the circular muscle of the guinea-pig colon and strongly suggest that the apamin-sensitive and the apamin-resistant components of the evoked ij.p. utilize different mechanisms for the secretion of theNANC transmitters, ATP and NO, respectively.
THE CIRCULAR PATH OF THE PATELLA AROUND THE TROCHLEAR AXIS (2011)

Differing descriptions of patellar motion relative to the femur have resulted from many in-vitro and in-vivo studies. The aim of this study was to examine the tracking behaviour of the patella. We hypothesized that patellar kinematics would correlate to the trochlear geometry and that differing previous descriptions could be reconciled by accounting for differing alignments of measurement axes.

Seven normal fresh-frozen knees were CT scanned and their kinematics with quadriceps loading was measured by an optical tracker system and calculated in relation to the previously-established femoral axes. CT scans were used to reliably define frames of reference for the femur, tibia and the patella. A novel trochlear axis was defined, between the centres of best-fit medial and lateral trochlear articular surfaces spheres.

The path of the centre of the patella was circular and uniplanar (RMS error 0.3mm) above 16°±3° knee flexion. The distal end of the median ridge of the patella entered the groove at 6° knee flexion, and the midpoint at 22°. This circle was aligned 6.4° ± 1.6° (mean± SD) from the femoral anatomical axis, 91.2°±3.4° from the epicondylar axis, and 88.3°±3° from the trochlear axis, in the coronal plane. In the transverse plane it was 91.2°±3.4° and 88.3°±3° from the epicondylar and trochlear axes. Manipulation of the data to different axis alignments showed that differing previously-published data could be reconciled. When the anatomic axis of the femur was used to align the coordinates, there was an initial medial and then a lateral translation. Comparing this with the uniplanar and circular path of the center of the patella, it shows that the orientation of the femoral coordinate system affects the description of the patellar medial-lateral translation.

This study has shown the effect of using different coordinate systems on reporting the patellar translation. Choosing a femoral reference that is more in line with the plane of the circular path of motion and the trochlear groove in the coronal plane diminishes the reported subsequent lateral translation of the patella. Once the frame of reference had been aligned to the trochlear axis, there was minimum medial-lateral translation of the patella.
Simultaneous two-color snapshot view on ultrafast charge and spin dynamics in a Fe-Cu-Ni tri-layer (2020)

<strong>Ultrafast phenomena on a femtosecond timescale are commonly examined by pump-probe experiments. This implies multiple measurements where the sample under investigation is pumped with a short light pulse and has to be probed with a second pulse at various time delays to follow its dynamics. Recently, the principle of streaking extreme ultraviolet (XUV) pulses in the temporal domain has enabled recording the dynamics of system within a single pulse. However, separate pump-probe experiments at different absorption edges lack a unified timing, when comparing the dynamics in complex systems. Here we report on an experiment using a dedicated optical element and the two-color emission of the FERMI XUV free-electron laser to follow the charge and spin dynamics in composite materials at two distinct absorption edges, simultaneously. The sample, consisting of ferromagnetic Fe and Ni layers, is pumped by an infrared laser and probed by a two-color XUV pulse with photon energies tuned to the M-shell resonances of these two transition metals. The experiment geometry intrinsically avoids any timing uncertainty between the two elements and unambiguously reveals an approximately 100 fs delay of the magnetic response with respect to the electronic excitation for both Fe and Ni. This delay shows that the electronic and spin degrees of freedom are decoupled during the demagnetization process. We furthermore observe that the electronic dynamics of Ni and Fe show pronounced differences for the two probed photon energies while the demagnetization dynamics are similar. These observations underline the importance of simultaneous investigation of the temporal response of both charge and spin in multi-component materials. In a more general scenario, the experimental approach can be extended to continuous energy ranges, promising the development of jitter-free transient absorption spectroscopy in the XUV and soft X-ray regimes.</strong>
