Effect of water content in soil samples on the γ detection efficiency for HPGe γ spectrometer (2005)

The air drying soil samples which are sampled to survey environmental radioactivity may contain more or less water in them .In order to investigate the effect of water content on the γ detection efficiency for HPGe γ spectrometer, the Monte Carlo code MCNP4B is used to calculate the γ detection efficiency for the soil samples containing different extent of water and for different energy γ rays respectively. The relationship between the detection efficiency of γ rays charactering natural radioactive nuclides ()~(238)U,()~(232)Th,()~(226)Ra,()~(40)K and water content is presented in this paper.
Vascular NADH/NADPH Oxidase Is Involved in Enhanced Superoxide Production in Spontaneously Hypertensive Rats (2000)

This study was designed to test the hypothesis that stimulation of nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phosphate (NADH/NADPH) oxidase is involved in increased vascular superoxide anion (*O(2)(-)) production in spontaneously hypertensive rats (SHR). The study was performed in 16-week-old and 30-week-old normotensive Wistar-Kyoto rats (WKY(16) and WKY(30), respectively) and in 16-week-old and 30-week-old SHR (SHR(16) and SHR(30), respectively). In addition, 16-week-old SHR were treated with oral irbesartan (average dose 20 mg/kg per day) for 14 weeks (SHR(30)-I). Aortic NADH/NADPH oxidase activity was determined by use of chemiluminescence with lucigenin. The expression of p22phox messenger RNA was assessed by competitive reverse transcription-polymerase chain reaction. Vascular responses to acetylcholine were determined by isometric tension studies. Aortic wall structure was studied, determining the media thickness and the cross-sectional area by morphometric analysis. Whereas systolic blood pressure was significantly increased in the 2 groups of hypertensive animals compared with their normotensive controls, no differences were observed in systolic blood pressure between SHR(30) and SHR(16). No other differences in the parameters measured were found between WKY(16) and SHR(16). In SHR(30) compared with WKY(30), we found significantly greater p22phox mRNA level, NADH/NADPH-driven *O(2)(-) production, media thickness, and cross-sectional area and an impaired vasodilation in response to acetylcholine. Treated SHR had similar NADH/NADPH oxidase activity and p22phox expression as the WKY(30) group. The vascular functional and morphological parameters were improved in SHR(30)-I. These findings suggest that an association exists between p22phox gene overexpression and NADH/NADPH overactivity in the aortas of adult SHR. Enhanced NADH/NADPH oxidase-dependent *O(2)(-) production may contribute to endothelial dysfunction and vascular hypertrophy in this genetic model of hypertension.

Imaging with obscured pupils (1977)

It is shown that diffraction-limited imaging systems with symmetric pupils and a noncentral obscuration yield a higher concentration of energy near the center of an image of a point object than those with central obscuration.
Experimental osteomyelitis (1983)

A variety of new antimicrobial agents has been introduced, but evaluation of the value of these agents in infections of the musculoskeletal system has relied almost exclusively on clinical trials. Preclinical trials in an animal model could permit earlier detection of promising agents and proper dosage schedules. Newer surgical procedures utilized in the treatment of osteomyelitis, such as local muscle flaps and free vascularized flaps, could also be evaluated to determine how they influence the local blood supply and microbial persistence. In addition, the animal model might aid in the evaluation of newer and non-invasive diagnostic scanning techniques used in the study of infection.

Identification of a putative RNA helicase in<i>E.coli</i> (1990)

The human p68 protein, an SV40 large T related antigen, is an RNA dependent ATPase and RNA helicase. It belongs to a new large and highly conserved gene family, the DEAD box proteins, whose members are involved in a variety of processes requiring manipulation of RNA secondary structure such as translation and splicing. Multiple DEAD box genes are present in S.cerevisiae, but only one has previously been described in E.coli. Low stringency screening of an E.coli genomic library with a p68 cDNA probe led to the identification of dbpA, a new E.coli DEAD box gene located at 29.6 minutes on the W3110 chromosome. We report here the nucleotide and deduced amino acid sequences of the gene. We have overexpressed dbpA from its own promoter on a high copy number plasmid and identified the gene product as a approximately 50 kD protein by immunoblotting with an anti-DEAD antibody.
Contribution to the Interpretation of Phase Diagrams by Ceramists (1951)

An attempt is made to eliminate some of the difficulties which hamper the proper use of phase diagrams by ceramists. It is contended that equilibrium is more nearly approached in ceramic bodies than is generally realized. Accordingly, phase diagrams are believed to be capable of more general application than has been previously recognized. The significance of primary fields is discussed, and the harmful results of the overemphasis of these features of phase diagrams are illustrated with examples from the literature. The useful role of the much‐neglected compatibility triangles in the ceramic application of the diagrams is emphasized. The relation of invariant points, melting intervals, and courses of melting to the firing behavior of ceramic bodies is indicated. It is believed that the conclusions drawn largely from the consideration of the MgO–Al 2 O 3 –SiO 2 diagram are of general application, except possibly in the case of the alkalialumina–silica systems.
DEVELOPMENT OF EXPERIMENTALLY BASED STRUCTURAL/ACOUSTIC AUTOMOBILE TIRE NOISE MODELS (1994)

At the present time, analytical methods cannot be used to accurately predict tire noise over the entire structural-acoustic frequency range. Therefore, efforts have focused on the development of experimentally based tire noise models. In this paper, results from a tire noise model developed for a mid-sized domestic automobile are presented. Issues regarding the number of forces and discrete pressure locations required to characterize the source are discussed. In addition, the appropriate experimental boundary conditions and measurement methodology are addressed.
The Relationship between Liver Function Tests and Alcohol Intake in Patients Admitted to an Alcoholism Unit (1984)

Values of various blood plasma tests have been determined in heavy drinkers admitted to an Alcoholism Unit and in a reference group of occasional social drinkers. These tests were total protein, albumin, bilirubin, alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), aspartate amino transferase (AST) and amylase. The aim of this study was to assess the reliability and validity of GGT and AST as indices of alcohol intake in heavy drinkers entering an Alcoholism Unit. The data indicate that in the patients group intra-personal variance and analytical variances are relatively small compared with the between-person variance. The data also indicate, however, that in the patients group GGT and AST are not valid group indices of alcohol intake since the between-person variation is large and the correlation with alcohol intake is weak due to large differences in the dose-response relationship between individuals. AST and GGT are poor indicators of alcohol intake in admissions to an Alcoholism Unit.

Synthesis and antitumor activity of 2-.beta.-D-ribofuranosyloxazole-4-carboxamide (oxazofurin) (1990)

Condensation of 3,4,6-tri-O-benzoyl-2,5-anhydro-D-allonyl chloride (4) with ethyl 2-amino-2-cyanoacetate (5) provided 2-[(3',4',6'-tri-O-benzoyl-2',5'-anhydroallonyl)amino]-2-cyanoa cetate (6). Compound 6 was treated with hydrogen chloride gas to give ethyl 5-amino-2-(2',3',5'-tri-O-benzoyl-beta-D- ribofuranosyl)oxazole-4-carboxylate (8). Reductive dediazotization of blocked nucleoside 8 provided ethyl 2-(2',3',5'-tri-O- benzoyl-beta-D-ribofuranosyl)oxazole-4-carboxylate (10), which after deblocking with sodium methoxide and ammonolysis was converted to 2-beta-D-ribofuranosyl-oxazole-4-carboxamide (oxazofurin, 3), an analogue of the antitumor and antiviral C-nucleoside tiazofurin (1). Oxazofurin (3) was found to be cytotoxic toward B16 murine melanoma cells in culture but inactive against murine leukemia P388 and L1210.
Three-junction solar cells comprised of a thin-film GaInP/GaAs tandem cell mechanically stacked on a Si cell (2002)

Three-junction tandem solar cells were fabricated by mechanical stacking of a thin-film GaInP/GaAs monolithic tandem cell and a Si cell. The epitaxial lift-off (ELO) technique was used for the thinning of GaInP/GaAs tandem cells. Both spectral responses of the GaInP top cell and the GaAs middle cell in the thin-film GaInP/GaAs monolithic tandem cell were conserved. The Si cell performance has been improved by reducing the absorption loss in the GaAs substrate.
Using <i>Galleria mellonella</i>–<i>Candida albicans</i> Infection Model to Evaluate Antifungal Agents (2013)

Candida albicans is the most common fungal pathogen. Galleria mellonella is widely used as an infection model host. Nevertheless, the G. mellonella-C. albicans infection model had not been optimized for drug evaluation before this study. In this work, we revealed that 5 × 10(5) colony forming unit (CFU)/larva was a suitable inoculum to optimize the G. mellonella-C. albicans infection model in order to evaluate antifungal agents. Using our optimized model, the antifungal effect of fluconazole, amphotericin B and flucytosine, and the synergy between amphotericin B and flucytosine were successfully verified. Thus, this study provides a rapid, inexpensive and reliable way to evaluate antifungals in vivo.
Impact of ionic liquid pretreated plant biomass on Saccharomyces cerevisiae growth and biofuel production (2011)

Inhibitory compounds generated by the pretreament of lignocellulose processes can have negative impacts on downstream microbial growth and biofuel production. As such they present a significant barrier to the commercialization of biofuels produced using renewable carbon sources. Inhibitors are derived from the transformation of monosaccharides into toxic compounds and can also be an intrinsic component of the pretreatment reagents or biomass. Ionic liquid (IL) pretreatment has recently received attention as a potential alternative to established pretreatment techniques, but there are no published studies on its impact on downstream processes. In this study, sugars produced through the enzymatic hydrolysis of biomass pretreated with the IL 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) were used to assess the impact of IL pretreatment on cell growth and production of ethanol by Saccharomyces cerevisiae. Residual 1-ethyl-3-methylimidazolium ion ([C2mim]+) in hydrolysates was found to be the primary source of inhibition on downstream microbial growth and ethanol production.
[High level secretion expression of PoIFNalpha in Pichia pastoris]. (2005)

The porcine alpha interferon gene was inserted into the Pichia pastoris expression vector of pPICZalphaA which contains AOX I promoter and alpha-factor signal sequence. The recombinant plasmid was transformed into host cell E.coli JM109 and then was extracted for analysis of restriction enzymes. It was confirmed that heterogeneous gene spliced into vector pPICZalphaA was IFNalpha gene. The recombinant plasmid of pPICZalphaA-IFNalpha was linearnized by Sac I and transformed into KM71 by electroporation. SDS-PAGE and Western blot analysis showed that IFNalpha product was observed in the supernants with a little larger molecular weight size than the natural IFNalpha. The rIFN gene has the same antigenicity as natural one. The expressed rIFN accumulated up to about 0.45mg/mL. The cytokine activity of the supernantants was vertified by WISH/VSV system,which is about 2.1x10(4)IU/mL.
IL-3-dependent growth of basophil-like cells and mastlike cells from human bone marrow. (1989)

Human bone marrow cultured in the presence of human rIL-3 has been reported to give rise to basophils. In contrast, mouse bone marrow, cultured in the presence of mouse IL-3, leads to the growth of mast cells. To determine if human rIL-3 might also stimulate the growth of human mast cells, we cultured human bone marrow in the presence of human rIL-3 in suspension cultures, methylcellulose, and in "interphase" cultures where cells are layered over agar. The presence of mast cells was determined using a variety of histochemical techniques. In agreement with previous reports, basophil-like cells were identified in all culture systems. Mastlike cells were identified only in interphase cultures. By 3 wk, such cultures consisted of basophil-like cells (20 to 50%) and mastlike cells (1 to 5%). Cultures supplemented with rIL-4 showed no additional increase in basophil-like and mastlike cells. Both basophil-like and mastlike cells fluoresced with o-phthaldialdehyde and exhibited IgE receptors. Unlike basophil-like cells, mastlike cells were chloroacetate esterase, amidase, and human mast cell tryptase positive. We conclude that human rIL-3 can support the growth of human mastlike cells under selected culture conditions.

Influence of Small Grain Crops on Weeds and Ecofallow Corn (<i>Zea mays</i>) (1995)

Spring small grains were not as competitive with barnyardgrass and witchgrass as winter wheat. Winter wheat grain yields were greater than spring barley or spring wheat in 1986, 1987, and 1988 and oat in 1986 and 1988. Barnyardgrass, stinkgrass, and witchgrass control with glyphosate plus 2,4-D plus atrazine at 0.6 plus 0.8 plus 1.7 kg ha −1 was usually less when the herbicides were applied to stubble of spring small grain versus winter wheat due to the advanced weed growth at treatment Barnyardgrass and witchgrass were more difficult to control than stinkgrass, redroot pigweed, tumble pigweed, kochia, and tumble thistle. No-till corn planted into winter wheat stubble had fewer barnyardgrass and witchgrass than corn planted into spring wheat stubble. The addition of metolachlor plus atrazine at 1.7 plus 0.6 kg ha −1 eliminated differences among small grain cultivars in weed control in corn. Corn grain yields from winter wheat plots were greater than other small grains in 1989 because of better weed control and more crop residue.
Telepathology diagnosis of prostate needle biopsies (1997)

We conducted a prospective analysis of the diagnostic accuracy of a static-image telepathology system (Roche RIAS, Elon College, NC) in the interpretation of needle biopsies of the prostate (NBx). Two hundred consecutive cases received in consultation were included. Each case was examined by one of the researchers (MHW), and images were captured either according to the areas of concern designated by the referring pathologist (set A; 100 cases) or according to the judgment of MHW (set B; 100 cases). The other researcher (JIE) daily rendered diagnoses first on the video images and then by direct microscopy. Accuracy of video diagnosis was categorized as 0 (correct), 1 (minor error), 2 (major error), or 3 (deferred). An average of 5.49 images were captured per case in set A, and 5.28 for set B. Seventy-seven, 9, 9, and 5 cases were categorized as 0, 1, 2, and 3, respectively, for set A, and 78, 17, 1, and 4 cases, respectively, for set B. Video versus direct diagnoses for the type 2 errors were five carcinoma versus markedly atypical, two carcinoma versus atypical, one carcinoma versus nonspecific granulomatous prostatitis, and two benign versus atypical. In these difficult NBx, telepathology allowed an essentially correct diagnosis in almost all of the cases. The number of images required was reasonable, and the images were of excellent quality. However, the accuracy varied from set A to set B, with the fractions of nondeferred cases that were given an essentially correct video diagnosis totaling 91% and 99%, respectively (P < .01). Accuracy of telepathology diagnosis using static images may depend on the person capturing the images, even in the case of small biopsies.
DOES COLCHICINE WORK? THE RESULTS OF THE FIRST CONTROLLED STUDY IN ACUTE GOUT (1987)

We have performed the first controlled study of colchicine in acute gout, to determine its efficacy and toxicity, and to define the natural history of acute gout. Two-thirds of colchicine-treated patients improved after 48 hours, but only one-third of the patients receiving placebo demonstrated similar improvement. The colchicine-treated patients responded earlier; significant differences from placebo were shown after 18-30 hours. All patients given colchicine developed diarrhea after a median time of 24 hours (mean dose of colchicine 6.7 mg). This side effect occurred before relief of pain in most patients.

Handwritten Bangla Compound Character Recognition Using Gradient Feature (2007)

Recognition of handwritten characters of Indian script is difficult because of the presence of many complex shaped compound characters (cluster characters) as well as variability involved in the writing style of different individuals. This paper deals with recognition of off-line Bangla handwritten compound characters using modified quadratic discriminant function (MQDF). The features used for recognition purpose are mainly based on directional information obtained from the arc tangent of the gradient. To get the feature, at first, a 2 times 2 mean filtering is applied 4 times on the gray level image and a non-linear size normalization is done on the image. A Roberts filter is then applied on the normalized image to obtain gradient image. Next, the arc tangent of the gradient (direction of gradient) is initially quantized into 32 directions and the strength of the gradient is accumulated with each of the quantized direction. Finally, the frequencies of these directions are down sampled using Gaussian filter to get 392 dimensional feature vectors. Using 5-fold cross validation technique we obtained 85.90% accuracy from a dataset of Bangla compound characters containing 20,543 samples.
