MANAGEMENT OF PLANT VIRAL DISEASES THROUGH CHEMICAL CONTROL OF INSECT VECTORS (1999)

In this article we consider the role of epidemiological factors and transmission processes of insect-vectored viruses on the effectiveness of insecticides in a disease management program. We also discuss the use of insecticides within the broader framework of the chemical environment surrounding vectors, and how chemical-induced alterations in the behavior of vectors can influence transmission. Our analysis confirms the belief of Heathcote, who stated in 1973, that "no one method of control is likely to keep crops entirely free from virus infection and as many preventative measures should be taken as are economically justified."
Partial Characterization of Bifidobacterium breve C50 Cell-free Whey Compounds Inducing Modifications to the Intestinal Microflora (2002)

Cell-free whey obtained from milk fermented with Bifidobacterium breve C50 (Bb C50) has been shown to modify the intestinal flora in humans and mice. Previous work showed that no antibiotic-like or barrier effect due to overgrowing bifidobacteria was implied in the microbial modifications. The present study was focused on characterizing the compounds and mechanisms involved. Protein, sugar, and enzymatic profiles of Bb C50 whey were therefore determined and compared to those of a whey unable to modify the intestinal flora of humans and mice. No remarkable difference was noted except for a higher lactosidase activity in Bb C50 whey. Various physical treatments were then applied to fractions of Bb C50 whey. Activity was assessed in C3H mice by analyzing changes in the intestinal flora balance throughout a 15-d administration of each treated whey. Heating at 80 degrees C and aerobic storage for 2 wk completely abolished Bb C50 whey activities. In contrast, the addition of a reducing agent (cysteine hydrochloride), either at the beginning of a 15-d aerobic storage or prior to administration, as well as preserved these activities. Susceptibility to heating and oxidation suggested that an enzyme might play a role in the induced microbial changes. Since the Bb C50 lactosidase was partly inactivated by the oxidative treatment, it could support the in vivo activity. The enzyme might reach the intestinal lumen and partly degrade substrates, such as mucins, usually used by the intestinal flora. The released molecules might then favor the development of a new microbial balance.
Highly Selective SiO<sub>2</sub> Etch Employing Inductively Coupled Hydro-Fluorocarbon Plasma Chemistry for Self Aligned Contact Etch (1997)

An inductively coupled plasma chemistry including hydro-fluorocarbon gas ( CHF 3 , CH 2 F 2 or CH 3 F) in addition to C 4 F 8 and Ar was developed for the self aligned contact process of LSI. The additional gases effectively reduces the etch rate of the nitride stopper in the contact hole resulting an increased selective ratio. The effect becomes more marked with higher H numbers. The optical emission signals of both F radical and carbon, including radicals such as C 2 , CF and CF 2 , were decreased by the addition of CH 3 F. The improved selectivity is considered to be due to the increased concentration of radicals with C–H bonding. The effect of C–H including radicals was explained by the enthalpy of reaction with oxygen and nitrogen atoms to form CO or CN bonding, and an improved step coverage of the polymerized film protecting the nitride surface.
Mössbauer and magnetization studies of nickel ferrites (1993)

Nickel ferrites have been produced by the rf plasma deposition technique for the first time. This technique has promise for large scale fine particle production of ferrites. Powder x-ray diffraction linewidth measurements show an average particle size of about 55 nm. Mossbauer measurements show the presence of both the nickel ferrite and the nickel zinc ferrite with Fe3O4 created in each ferrite production process as an impurity. Magnetization and Mössbauer measurements show evidence that the aerosol prepared samples have small particle characteristics as compared to solid state reacted bulk materials.
<title>Moire interferometric alignment and overlay techniques</title> (1994)

Moire alignment and overlay measurement techniques with nm-scale precision are demonstrated. Using 0.47-micrometers pitch gratings, a 1-nm alignment resolution is demonstrated. A novel double-period moire grating is used to provide both coarse (approximately 10 micrometers ) and fine (approximately 1 micrometers ) capture ranges for integration with existing stage positioning systems. A new diffraction-order interferometry technique for nm-precision remote overlay readout, with potential application to latent image structures immediately after exposure, is demonstrated.
Alpinia: the gold mine of future therapeutics (2012)

Since prehistoric era, plant-derived drugs were much preferred due to their less side effects than drugs of synthetic origin. Bioassay-guided selection of active fraction of a plant extract and further isolation and characterization of the pure bioactive compounds are in practice in both academic and industrial research. Zingiberaceae, a medicinally important, ornamental, monocotyledonous family has potential members in the tribe Alpinieae, among which the genus Alpinia is studied under this current review due to its wide range of biomedical applications. The members in the genus possess many bioactive compounds against harmful microbes to deadly diseases like cancer by regulating the different signalling pathway systems. Several compounds have been discovered and found to deliver diversified biological efficacy either in vitro or in vivo against a range of diseases. The chemical profiling of the genus and investigation of crude essential oils and individual bioactive compounds towards the therapeutic importance in various disciplines have been documented in the current review.

Effect of platelet-activating factor antagonist and leukotriene antagonist on endotoxin shock in the rat: role of the leukocyte. (1992)

The effects of platelet-activating factor (PAF) antagonist (CV-3988) and leukotrienes (LTs) antagonist (ONO-1078) on endotoxin-induced sequelae in the rat were assessed. Pretreatment with either CV-3988 (6 mg/kg, i.v.) or ONO-1078 (150 mg/kg, p.o.) did not improve survival rate following the administration of Escherichia coli lipopolysaccharide (LPS) compared with that of control rats pretreated with solvents of the drugs. Rats pretreated with both CV-3988 and ONO-1078 exhibited significantly (P less than 0.01) enhanced survival following lipopolysaccharide (LPS) administration. Percentage survivals 48 hr after the administration of LPS were 20%, 32%, 24%, and 68% in the pretreatment with solvents, CV-3988, ONO-1078, and CV-3988 combined with ONO-1078 groups, respectively. Pretreatment with CV-3988 combined with ONO-1078 inhibited the change of plasma transaminase 3 hr after LPS administration. The neutropenia, due to the administration of vinblastine (1 mg/kg, i.v.), increased the survival rate following the administration of LPS without pretreatment with PAF and LT antagonists. Antishock action of CV-3988 and ONO-1078 could not be seen in neutropenic rats. These data suggest that combined pretreatment with PAF antagonist and LT antagonist inhibited leukocyte-mediated tissue injury in LPS-induced endotoxemia.
Surgical Treatment of Atrial Fibrillation Using Argon-Based Cryoablation During Concomitant Cardiac Procedures (2005)

Cryoablation using this flexible argon-based device for the treatment of AF during concomitant cardiac procedures was safe and effective, with 88.5% of patients free from AF at 12 months.
Recent advances in chemiluminescence detection coupled with capillary electrophoresis and microchip capillary electrophoresis (2015)

CE is an ideal analytical method for extremely volume-limited biological microenvironments. However, the small injection volume makes it a challenge to achieve highly sensitive detection. Chemiluminescence (CL) detection is characterized by providing low background with excellent sensitivity because of requiring no light source. The coupling of CL with CE and MCE has become a powerful analytical method. So far, this method has been widely applied to chemical analysis, bioassay, drug analysis, and environment analysis. In this review, we first introduce some developments for CE-CL and MCE-CL systems, and then put the emphasis on the applications in the last 10 years. Finally, we discuss the future prospects.
Declarative reasoning about the structure of object-oriented systems (2002)

The structure of object-oriented systems typically forms a complicated tangled web of interdependent classes. Understanding this implicit and hidden structure poses severe problems to developers and maintainers who want to use, extend or adapt those systems. This paper advocates the use of a logic meta-language to express and extract structural relationships in class-based object-oriented systems. As validation the logic meta-language SOUL was implemented and used to construct a declarative framework that allows reasoning about the structure of Smalltalk programs. The declarative framework's usefulness is illustrated by expressing different high-level structural relationships such as those described by design patterns.
The feasibility of three-dimensional displays of the thorax for preoperative planning in the surgical treatment of lung cancer (2007)

It is feasible to use 3D displays of the thorax for preoperative planning in treating lung cancer. Using 3D displays in surgical treatment of lung cancer has potential benefits, once the technique is perfected.
Data transformation for neural network models in water resources applications (2003)

A step that should be considered when developing artificial neural network (ANN) models for water resources applications is the selection of an appropriate transformation of the data. In general, the primary motivations for data transformation are: (1) to scale the data so as to be commensurate with the transfer function in the output layer; (2) to standardise each of the variables; (3) to provide a suitable initialization of the ANN; and (4) to modify the distribution of the input variables to provide a better mapping to the outputs. In this paper, five different transformations are investigated in an attempt to improve the ANN's forecasting ability. These are: linear transformation, logarithmic transformation, histogram equalization, seasonal transformation and a transformation to normality. A case study is presented in which each of the ANN models developed using the different transformation techniques is used to forecast salinity in the River Murray at Murray Bridge (South Australia) 14 days in advance. When tested on a validation set from July 1992 to March 1998, the model developed using the linear transformation resulted in the lowest root mean squared forecasting error. This finding further strengthens the claim that the probability distribution of the data does not need to be known to develop effective ANN models. No improvement in the ANN model's forecasting ability was made using the logarithmic, seasonal and normality transformations. The model developed using histogram equalization produced good results for data within the training domain but was not robust on new patterns outside of the calibration range.
Post-operative atrial fibrillation: a maze of mechanisms (2011)

Post-operative atrial fibrillation (POAF) is one of the most frequent complications of cardiac surgery and an important predictor of patient morbidity as well as of prolonged hospitalization. It significantly increases costs for hospitalization. Insights into the pathophysiological factors causing POAF have been provided by both experimental and clinical investigations and show that POAF is 'multi-factorial'. Facilitating factors in the mechanism of the arrhythmia can be classified as acute factors caused by the surgical intervention and chronic factors related to structural heart disease and ageing of the heart. Furthermore, some proarrhythmic mechanisms specifically occur in the setting of POAF. For example, inflammation and beta-adrenergic activation have been shown to play a prominent role in POAF, while these mechanisms are less important in non-surgical AF. More recently, it has been shown that atrial fibrosis and the presence of an electrophysiological substrate capable of maintaining AF also promote the arrhythmia, indicating that POAF has some proarrhythmic mechanisms in common with other forms of AF. The clinical setting of POAF offers numerous opportunities to study its mechanisms. During cardiac surgery, biopsies can be taken and detailed electrophysiological measurements can be performed. Furthermore, the specific time course of POAF, with the delayed onset and the transient character of the arrhythmia, also provides important insight into its mechanisms. This review discusses the mechanistic interaction between predisposing factors and the electrophysiological mechanisms resulting in POAF and their therapeutic implications.
Human alternative complement pathway: membrane-associated sialic acid regulates the competition between B and beta1 H for cell-bound C3b. (1979)

There is a tension in any ethical evaluation of mobility. On the one side mobility is linked to elements of progress, cosmopolitism, autonomy, and freedom. On the other side increasing mobility causes worries with regard to safety and sustainability. This essay analyzes a suggested technical solution to the worries about safety and sustainability: the increasing usage of persuasive technologies to change individual behavior. Can and should we moralize mobility technologies by way of persuasion?
A new facultative anaerobic xylan-using alkalophile lacking cytochrome, quinone, and catalase. (1987)

A facultative anaerobic xylan-using alkalophile has been isolated from an alkalophilic compost fermented for the screening. The strain was gram-positive in the very early stages of growth, and is a sporeforming rod. The strain having anteiso-, iso-branched, and straight-chain cellular fatty acids, lacked cytochrome, quinone, and catalase. It was a facultative anaerobe, whose μmax of aerobic and anaerobic culture were 0.70 h-1 and 0.82 h-1, respectively. Xylanase activity was higher in anaerobic culture than aerobic culture. In static culture, after sharp consumption of oxygen in the medium, xylanase production started. The main fernjentation products from xylan in anaerobic or static culture were formic acid, ethanol, acetic acid, and pyruvic acid, and were acetic and pyruvic acids in aerobic culture. The strain has new characteristics of production of metabolites and xylanase, and has new intermediate characteristics between the genera Bacillus and Clostridium.
A molecular marker closely lined to the male sterile Ms2 gene in common wheat (Triticum aestivum) (2008)

A male sterile wheat mutant named ‘Taigu’ was found in a wheat field in China in 1972. The male sterility is controlled by a single dominant gene that was referred to as Ms2. Recently this gene was linked to a dwarfing gene through crossing ‘Taigu’ with the short wheat ‘Aibian 1’ carrying the dwarfing gene Rht-D1c. The objective of this study was to develop molecular markers linked to the male sterility Ms2 gene in common wheat. One hundred and twenty two near isogenic lines were developed through backcrossing and sib inter-crossing, and used for the development of molecular markers. In the SSR analysis, after screening 48 pairs of SSR primers, a marker, ms2wmc617, was identified closely linked to the male sterile Ms2 gene and mapped at the distal position of chromosome 4DS. The use of the molecular marker ms2-wmc617 can facilitate recurrent selection in a wheat breeding program. In addition, the marker is at the same locus as the dwarfing gene Rht-D1c. Thus, the identification of the molecular marker, followed by the development of a fine genetic map of chromosome 4DS, could provide a firm foundation for cloning both Ms2 and Rht-D1c genes.

Asymmetric Hydrogenation of <i>tert</i>-Alkyl Ketones (2005)

A combined system of RuCl2(tolbinap)(pica) and an alkaline or organic phosphazene base catalyzes asymmetric hydrogenation of sterically congested tert-alkyl ketones (TolBINAP = 2,2'-bis(di-4-tolylphosphino)-1,1'-binaphthyl, PICA = alpha-picolylamine). Hydrogenation with RuH(eta1-BH4)(tolbinap)(pica) does not require any strong base. Alcoholic solvents strongly affect the catalytic efficiency. The reaction proceeds smoothly in ethanol under 1-20 atm of H2 and at room temperature with a substrate to catalyst molar ratio of up to 100 000. Various aliphatic, aromatic, heteroaromatic, and olefinic tert-alkyl ketones are convertible to the corresponding chiral carbinols in high enantiomeric purity. Olefinic and heteroaromatic functions are left intact. Certain cyclic ketones are also usable. The mode of enantioface selection is consistent and predictable.
The Efficiency of Cell Fusion-Based Reprogramming Is Affected by the Somatic Cell Type and the <i>In Vitro</i> Age of Somatic Cells (2011)

Cell fusion is one approach that has been used to demonstrate nuclear reprogramming of somatic cells to a pluripotent-like state and is a useful tool for screening factors involved in reprogramming. Recent cell fusion studies reported that the overexpression of Nanog and SalI could improve the efficiency of reprogramming, whereas AID was shown to be essential for DNA demethylation and initiation of reprogramming. The aim of this study was to investigate factors affecting the reprogramming efficiency following cell fusion. We conducted fusions of mouse embryonic stem cells (ESCs) with somatic cells carrying a GFP transgene under control of the Oct4 promoter (Oct4-GFP), which is normally repressed in nonpluripotent cells. The effect of somatic cell type on the reprogramming efficiency was investigated using Oct4-GFP expression as an indicator. Different somatic cell types were tested including mesenchymal stem cells (MSCs), adipose tissue-derived cells (ADCs), neural stem cells (NSCs), and these were compared with the mouse embryonic fibroblast (mEF) standard. The reprogramming efficiencies differed greatly, with mEFs (0.477 ± 0.003%) and MSCs (0.313 ± 0.003%) showing highest efficiencies while NSCs (0.023 ± 0.014%), and ADCs (0.006 ± 0.006%) had significantly lower reprogramming efficiencies (p < 0.05). The differences in the reprogramming efficiencies observed could be in part explained by the in vitro age of the somatic cells used. We demonstrated that the reprogramming efficiency of early passage mEFs was significantly higher compared with late passage mEFs (0.330 ± 0.166% vs. 0.021 ± 0.011%, p < 0.05), suggesting that senescence can affect reprogramming potential. In summary, this study shows that different somatic cell types do not have equivalent potential to be reprogrammed following fusion with ESCs. Furthermore, the in vitro age of somatic cells can also affect the reprogrammability of somatic cells. These findings constitute an important consideration for reprogramming studies.
Characterization of a baculovirus gene encoding a small conotoxinlike polypeptide (1992)

We identified a gene of Autographa californica nuclear polyhedrosis virus (AcMNPV) that encodes a small cysteine-rich polypeptide which has size and sequence similarity to omega-conotoxins, a class of calcium ion (Ca2+) channel inhibitors, found in the venom of cone snails. Transcriptional analysis indicated that the 159-bp open reading frame, which we named ctl, and a downstream 984-bp open reading frame are transcribed as a single 1.3-kb bicistronic late RNA. The mature ctl gene product was identified as a small secreted protein by high-pressure liquid chromatography fractionation of extracellular fluid. Viruses with a site-specific deletion in ctl appeared normal with regard to the kinetics and virulence of infection, both in vitro and in vivo. Although we studied the behavior of wild-type and mutant virus-infected insects in some detail, a biological role for ctl in AcMNPV infection remains to be established.
