Review of Pharmacological Properties and Chemical Constituents of <i>Pimpinella anisum</i> (2012)

Pimpinella anisum (anise), belonging to Umbelliferae family, is an aromatic plant which has been used In Iranian traditional medicine (especially its fruits) as carminative, aromatic, disinfectant, and galactagogue. Because the wide traditional usage of Pimpinella anisum for treatment of diseases, in this review published scientific reports about the composition and pharmacological properties of this plant were collected with electronic literature search of GoogleScholar, PubMed, Sciencedirect, Scopus, and SID from 1970 to 2011. So far, different studies were performed on aniseeds and various properties such as antimicrobial, antifungal, antiviral, antioxidant, muscle relaxant, analgesic and anticonvulsant activity as well as different effects on gastrointestinal system have been reported of aniseeds. It can also reduce morphine dependence and has beneficial effects on dysmenorrhea and menopausal hot flashes in women. In diabetic patients, aniseeds showed hypoglycemic and hypolipidemic effect and reduce lipid peroxidation. The most important compounds of aniseeds essential oil were trans-anetole, estragole, γ-hymachalen, para-anisaldehyde and methyl cavicol. Due to broad spectrum of pharmacological effects, and very few clinical studies of Pimpinella anisum, more clinical trials are recommended to evaluate the beneficial effects of this plant in human models and synthesis of new drugs from the active ingredients of this plant in future.
Fast and Selective Room-Temperature Ammonia Sensors Using Silver Nanocrystal-Functionalized Carbon Nanotubes (2012)

We report a selective, room-temperature NH(3) gas-sensing platform with enhanced sensitivity, superfast response and recovery, and good stability, using Ag nanocrystal-functionalized multiwalled carbon nanotubes (Ag NC-MWCNTs). Ag NCs were synthesized by a simple mini-arc plasma method and directly assembled on MWCNTs using an electrostatic force-directed assembly process. The nanotubes were assembled onto gold electrodes with both ends in Ohmic contact. The addition of Ag NCs on MWCNTs resulted in dramatically improved sensitivity toward NH(3). Upon exposure to 1% NH(3) at room temperature, Ag NC-MWCNTs showed enhanced sensitivity (~9%), very fast response (~7 s), and full recovery within several minutes in air. Through density functional theory calculations, we found that the fully oxidized Ag surface plays a critical role in the sensor response. Ammonia molecules are adsorbed at Ag hollow sites on the AgO surface with H pointing toward Ag. A net charge transfer from NH(3) to the Ag NC-MWCNTs hybrid leads to the conductance change in the hybrid.
Scan more with memory scan test (2009)

Almost all manufacturing memory test programs use the time-efficient Scan test to screen the defective chips in an early stage. Usually, Scan is used to screen out the easy-to-detect hard faults like stuck-at-faults. In this paper we will show how Scan can be modified to increase the fault coverage and detect unique faults. It will be shown that many additional faults are detectable using Scan if appropriate read-write sequence, an appropriate data-background and appropriate addressing method are used. Such additional faults consist not only of static/traditional faults, but also of dynamic and time-related faults which are of increasing importance with the technology scaling. Examples of such faults are dynamic faults in the peripheral circuits (e.g., sense amplifiers, pre-recharge circuits, etc) and in the address decoders. Industrial results are presented to validate the proposed approach.
A novel color mapping method for preferred color reproduction (2007)

We propose a novel color mapping method that generates smooth color transition and can accommodate the color preference. The method consists of two stages; rough calibration and black generation. The rough calibration process generates a three dimensional (3-D) Look-Up-Table converting input RGB data to printable CMY values. When the 3-D LUT is created, a new intent for color mapping, target color is internally used. The target color is predefined from a reference color book based on the color preferences of testers involved in the target definition phase. All of the input data of the 3-D LUT are mapped to the printable values in a printer based on the target color, and then simply converted to CMYK values. We evaluated the proposed algorithm comparing with a commercial printer profiler and found that the proposed algorithm makes better printing quality.
GS52 Ecto-Apyrase Plays a Critical Role during Soybean Nodulation   (2008)

Apyrases are non-energy-coupled nucleotide phosphohydrolases that hydrolyze nucleoside triphosphates and nucleoside diphosphates to nucleoside monophosphates and orthophosphates. GS52, a soybean (Glycine soja) ecto-apyrase, was previously shown to be induced very early in response to inoculation with the symbiotic bacterium Bradyrhizobium japonicum. Overexpression of the GS52 ecto-apyrase in Lotus japonicus increased the level of rhizobial infection and enhanced nodulation. These data suggest a critical role for the GS52 ecto-apyrase during nodulation. To further investigate the role of GS52 during nodulation, we used RNA interference to silence GS52 expression in soybean (Glycine max) roots using Agrobacterium rhizogenes-mediated root transformation. Transcript levels of GS52 were significantly reduced in GS52 silenced roots and these roots exhibited reduced numbers of mature nodules. Development of the nodule primordium and subsequent nodule maturation was significantly suppressed in GS52 silenced roots. Transmission electron micrographs of GS52 silenced root nodules showed that early senescence and infected cortical cells were devoid of symbiosome-containing bacteroids. Application of exogenous adenosine diphosphate to silenced GS52 roots restored nodule development. Restored nodules contained bacteroids, thus indicating that extracellular adenosine diphosphate is important during nodulation. These results clearly suggest that GS52 ecto-apyrase catalytic activity is critical for the early B. japonicum infection process, initiation of nodule primordium development, and subsequent nodule organogenesis in soybean.
Multigrating quasi-phase-matched optical parametric oscillator in periodically poled LiNbO_3 (1996)

We report a widely tunable quasi-phase-matched optical parametric oscillator that uses periodically poled LiNbO(3)with a multigrating structure. The device is tuned by translation of the crystal through the resonator and pump beam, with no realignment needed. With a 1.064-microm acousto-optically Q-switched Nd:YAG pumplaser, we produced noncritically phase-matched tunable IR output from 1.36 to 4.83 microm. The threshold was 6 microJ for a 26-mm interaction length. The extraordinary polarization of LiNbO(3) has better IR transmission than does the ordinary polarization, permitting operation at longer wavelengths with d(33) quasi-phase matching than with conventional Type I birefringent phase matching.
GlycoVis: Visualizing glycan distribution in the protein <i>N</i>‐glycosylation pathway in mammalian cells (2006)

Glycosylation has profound effects on the quality of recombinant proteins produced in mammalian cells. The biosynthetic pathways of N-linked glycans on glycoproteins involves a relatively small number of enzymes and nucleotide sugars. Many of these glycoconjugate enzymes can utilize multiple N-glycans as substrates, thus generating a large number of glycan intermediates, and making the biosynthetic pathway resemble a network with diverging and converging paths. The N-glycans on secreted glycoprotein molecules include not only terminal glycans, but also pathway intermediates. To better assess the glycan distribution and the potential route of their synthesis, we created GlycoVis, a visualization program that displays the distribution and the potential reaction paths leading to each N-glycan on the reaction network. The substrate specificities of the enzymes involved were organized into a relationship matrix. With the input of glycan distribution data, the program outputs a reaction pathway map which labels the relative abundance levels of different glycans with different colors. The program also traces all possible reaction paths leading to each glycan and identifies each pathway on the map. Glycoform distribution of Chinese Hamster Ovary cell-derived tissue plasminogen activator (TPA), and human and mouse IgG were used as illustrations for the application of GlycoVis. In addition, the intracellular and secreted IgG from an NS0 producer cell line were isolated, and their glycoform profiles were displayed using GlycoVis for comparison. This visualization tool facilitates the analysis of potential reaction paths utilized under different physiological or culture conditions, and may provide insight on the potential targets for metabolic engineering.
Constitutive and repressivle enzymes of the common pathway of aromatic biosynthesis in Escherichia coli K-12: regulation of enzyme synthesis at different growth rates (1976)

Synthesis of five of the enzymes of the common pathway of aromatic biosynthesis has been shown to be unaffected by either the aromatic amino acids--the product of the first reaction (3-deoxy-D-arabinoheptulosonic acid-7-phosphate) or the product of the last reaction (chorismate)--or by the state of regulator gene loci tyrR. On the other hand, the rate of synthesis of these enzymes, and of several other enzymes for which repression control was inactive because of mutations in relevant regulator genes, was found to change with growth rate. These changes were found to correlate at faster growth rates than those observed in glucose minimal medium with the alterations in the relative frequencies of the corresponding structural genes which occur at these growth rates. It was found that when wild-type cells were grown at these faster growth rates in medium lacking the aromatic amino acids, complete derepression of the tyrosine-inhibitable 3-deoxy-D-arabinoheptulosonic acid-7-phosphate synthetase occurred, in strong contrast to the situation when wild-type cells are grown in glucose minimal medium.
Napsin A, a New Marker for Lung Adenocarcinoma, Is Complementary and More Sensitive and Specific Than Thyroid Transcription Factor 1 in the Differential Diagnosis of Primary Pulmonary Carcinoma: Evaluation of 1674 Cases by Tissue Microarray (2012)

Nap-A is superior to TTF-1 in distinguishing primary lung ACA from other carcinomas (except kidney), particularly primary lung small cell carcinoma, and primary thyroid carcinoma. A combination of Nap-A and TTF-1 is useful in the distinction of primary lung ACA (Nap-A(+), TTF-1(+)) from primary lung squamous cell carcinoma (Nap-A(-), TTF-1(-)) and primary lung small cell carcinoma (Nap-A(-), TTF-1(+)).
4—METHODS OF TEST FOR THE FLAMMABILITY OF TEXTILE FABRICS (1968)

Three methods for the determination of the flammability of textile fabrics are presented. The methods are intended to replace two existing British Standards. The first method is applicable to textile fabrics generally (with the exception of floor-coverings), and the second method is intended as a confirmatory test for fabrics that do not bum when tested by the first method because they melt, shrink, or curl away from the flame; these fabrics include these manufactured predominantly from thermoplastic fibres. The third method is broadly suitable for pile fabrics and simulated-fur fabrics (except floor-coverings) and is intended solely for determining whether the pile of these fabrics will promote the rapid spread of a flame with which it is in transient contact; the total flammability is determined by using one of the other methods, as appropriate.
In vitro analysis of the rat liver-type arginase promoter (1991)

Genes for urea cycle enzymes including liver-type arginase are expressed mainly in the liver and are regulated developmentally, nutritionally, and hormonally in a coordinated manner. The promoter region of the rat arginase gene was investigated with an in vitro transcription system using nuclear extracts prepared from rat tissues. Accurate initiation of the transcription in liver nuclear extracts was confirmed by runoff analysis and S1 nuclease mapping. The arginase promoter was transcribed more efficiently in liver nuclear extracts than in brain extracts, reproducing the in vivo tissue specificity qualitatively. Analysis of deletion mutants of the 5'-flanking region in liver nuclear extracts revealed a positive regulatory region spanning nucleotides -90 to -51 relative to the transcription start site. Overlapping this region, two protected areas were detected by DNase I footprinting. Competition analysis with synthetic oligonucleotides showed that the more downstream protected area was occupied, in a mutually exclusive manner, by two factors each related to CTF/NF-1 and Sp1. The other more upstream protected area was recognized by a factor related to the liver-enriched transcription factor C/EBP, which was recently shown to interact with regulatory regions of two other urea cycle enzyme genes.

Transcatheter Arterial Chemoembolization of Hepatocellular Carcinoma: Prevalence and Causative Factors of Extrahepatic Collateral Arteries in 479 Patients (2006)

The presence of ExCAs supplying HCC is rather common, and the tumor size is a significant causative factor for the development of these collateral arteries.
The Repertoire of Killer Cell Ig-Like Receptor and CD94:NKG2A Receptors in T Cells: Clones Sharing Identical αβ TCR Rearrangement Express Highly Diverse Killer Cell Ig-Like Receptor Patterns (2001)

Killer cell Ig-like receptor (KIR) and CD94:NKG2A molecules were first defined as human NK cell receptors (NKR), but now are known to be expressed and to function on subpopulations of T cells. Here the repertoires of KIR and CD94:NKG2A expression by T cells from two donors were examined and compared with their previously defined NK cell repertoires. T cell clones generated from peripheral blood of both donors expressed multiple NKR in different combinations and used the range of receptors expressed by NK cells. In both donors alpha beta T cells less frequently expressed the inhibitory receptors CD94:NKG2A and KIR2DL1 than either gamma delta T cells or NK cells. In contrast to NK cells, not all NKR(+) T cells expressed an inhibitory receptor for autologous HLA class I. This lack of specific inhibitory NKR was especially apparent on alpha beta T cells of one donor. Overall, alpha beta T cells exhibited a distinct pattern of NKR expression different from that of gamma delta T and NK cells, which expressed highly similar NKR repertoires. In one donor, analysis of TCR rearrangement revealed a dominant subset of NKR(+) T cells sharing identical TCR alpha- and beta-chains. Remarkably, among 55 T cell clones sharing the same TCR alpha beta rearrangement 18 different KIR phenotypes were seen, suggesting that KIR expression was initiated subsequently to TCR rearrangement.
Identification of Glycosaminoglycans in Age-Related Macular Deposits (1996)

We investigated the presence and localization of glycosaminoglycans in basal laminar deposit and drusen in age-related maculopathy. Conventional histological staining techniques and monoclonal antibodies specific for several glycosaminoglycans were used on paraffin-embedded human maculae. Furthermore, macular homogenates were analyzed with two-dimensional electrophoresis. Quantitative analysis of glycosaminoglycans was done spectrophotometrically using dimethylmethylene blue. Immunohistochemically, all basal laminar deposit stained positive for chondroitin 4-sulfate and focally positive for heparan sulfate proteoglycan. Drusen were not stained with any of the monoclonal antibodies. With two-dimensional electrophoresis, it was demonstrated that macular extracts with and without age-related maculopathy contained chondroitin sulfate. Heparan sulfate was only expressed in maculae with age-related maculopathy. The total amount of glycosaminoglycans was significantly higher in maculae with basal laminar deposit than in maculae without basal laminar deposit (P = .001). There were significant differences in the amount and composition of glycosaminoglycans between maculae with and without age-related maculopathy.
Lysozyme level in blood serum of newly hatched White Leghorn chickens. (1978)

Ethylene glycol is an organic solvent used in extractive distillation to separate water–ethanol mixtures. An appropriate process description requires accurate physical property data. In this paper, experimental liquid densities and dynamic viscosities of pure ethylene glycol as well as the ternary system water–ethanol–ethylene glycol are presented over a wide temperature range (298.15 K to 328.15 K) at atmospheric pressure. A quadratic mixing rule was used to correlate the ternary liquid densities. The Eyring–Patel–Teja model with two Margules-type mixing rules for polar and aqueous systems is used to correlate the dynamic viscosity data over the measured ternary compositions and temperatures. An excellent agreement with experimental data is obtained. Additionally, the predictive ASOG-VISCO model demonstrated a good representation of the experimental data
Enhanced brain targeting of temozolomide in polysorbate-80 coated polybutylcyanoacrylate nanoparticles (2011)

This study indicates that polysorbate-80 coated PBCA nanoparticles could be a feasible carrier for temozolomide delivery to the brain. It is anticipated that the developed formulation may improve on targeted therapy for malignant brain tumors in the future.
Control of Cell Cycle and Cell Growth by Molecular Chaperones (2007)

Cells adapt their size to both intrinsic and extrinsic demands and, among them, those that stem from growth and proliferation rates are crucial for cell size homeostasis. Here we revisit mechanisms that regulate cell cycle and cell growth in budding yeast. Cyclin Cln3, the most upstream activator of Start, is retained at the endoplasmic reticulum in early G(1) and released by specific chaperones in late G(1) to initiate the cell cycle. On one hand, these chaperones are rate-limiting for release of Cln3 and cell cycle entry and, on the other hand, they are required for key biosynthetic processes. We propose a model whereby the competition for specialized chaperones between growth and cycle machineries could gauge biosynthetic rates and set a critical size threshold at Start.
Orbital Reconstruction and Covalent Bonding at an Oxide Interface (2007)

Orbital reconstructions and covalent bonding must be considered as important factors in the rational design of oxide heterostructures with engineered physical properties. We have investigated the interface between high-temperature superconducting (Y,Ca)Ba(2)Cu3O7 and metallic La(0.67)Ca(0.33)MnO3 by resonant x-ray spectroscopy. A charge of about -0.2 electron is transferred from Mn to Cu ions across the interface and induces a major reconstruction of the orbital occupation and orbital symmetry in the interfacial CuO2 layers. In particular, the Cu d(3z(2)-r(2)) orbital, which is fully occupied and electronically inactive in the bulk, is partially occupied at the interface. Supported by exact-diagonalization calculations, these data indicate the formation of a strong chemical bond between Cu and Mn atoms across the interface. Orbital reconstructions and associated covalent bonding are thus important factors in determining the physical properties of oxide heterostructures.
