Efficacy of <I>Beauveria bassiana</I> for Red Flour Beetle When Applied with Plant Essential Oils or in Mineral Oil and Organosilicone Carriers (2005)

The carriers mineral oil and Silwet L-77 and the botanical insecticides Neemix 4.5 and Hexacide were evaluated for their impacts on the efficacy of Beauveria bassiana (Balsamo) Vuillemin conidia against red flour beetle, Tribolium castaneum (Herbst), larvae. The dosages of liquid treatments were quantified by both conidia concentration in the spray volume and conidia deposition on the target surface. The latter approach allowed comparison with dry, unformulated conidia. The median lethal concentrations of B. bassiana in 0.05% Silwet L-77 solution or without a carrier were approximately double that for conidia in mineral oil. Carriers had highly significant effects on the efficacy of B. bassiana. The lower efficacy of conidia in aqueous Silwet L-77 may have been the result of conidia loss from the larval surface because of the siloxane's spreading properties. Neemix 4.5 (4.5% azadirachtin) delayed pupation and did not reduce the germination rate of B. bassiana conidia, but it significantly reduced T. castaneum mortality at two of four tested fungus doses. Hexacide (5% rosemary oil) caused significant mortality when applied without B. bassiana, but it did not affect pupation, the germination rate of conidia, or T. castaneum mortality when used in combination with the fungus.
Frozen shoulder and other shoulder disturbances in Parkinson's disease. (1989)

The frequency of shoulder disturbances, particularly frozen shoulder, has not been assessed previously in Parkinson's disease. In a survey of 150 patients compared with 60 matched control subjects a significantly higher incidence of both a history of shoulder complaints (43% vs. 23%) and frozen shoulder (12.7% vs. 1.7%) was found in the Parkinson's disease population. Those developing a frozen shoulder had initial disease symptoms indicative of akinesia twice as frequently as tremor while the ratio was reversed in those without frozen shoulder. In at least 8% of the patients frozen shoulder was the first symptom of disease, occurring 0-2 years prior to the onset of more commonly recognised features. Parkinson's disease should be added to the list of causes of frozen shoulder, and clinicians must be aware that the latter is often the presenting symptom of Parkinson's disease.
School-to-work transition and newcomer socialisation: The role of job-related education (2011)

Abstract This study investigated the interactive effects of on-the-job training (OJT), co-worker support (CWS), and supervisor support (SS) with newcomer job-related education (JRE), on newcomer adjustment. Given that socialisation is a learning process, an important factor in socialisation is job-related knowledge. Although many studies on organisational socialisation drew on new graduates making the school-to-work transition, they have not considered the role of JRE and associated job-related knowledge for socialisation. It was hypothesised that JRE and newcomer information-seeking will moderate the effects of OJT, CWS, and SS on role clarity, role conflict, and role orientation. The study was conducted with a sample 244 business and engineering graduates of an Asian university. Results provide some support for the moderating effects of JRE on role clarity and conflict. It was also found that SS was positively related to newcomer innovative role orientation. Implications for theory and practice are discussed.
Functional Star‐Like Polystyrenes as Organic Supports of MeDIP(2,6‐iPrPh)<sub>2</sub>FeCl<sub>2</sub> Catalyst Toward Ethylene Polymerization (2007)

Abstract Star‐like polystyrenes composed of a microgel core with functionalized arms have been designed and used as organic supports for a tridentate bis(imino)pyridinyl iron catalyst toward ethylene polymerization. In a first approach, star‐like polystyrenes bearing a few number of ethylene oxide units at the periphery of each arm have been prepared to immobilize, through nucleophilic interactions, common aluminum‐based activators [methylaluminoxane or trimethylaluminum (TMA)]. A second strategy is based on the synthesis of star‐like PS with arms ended either by a benzophenone or a benzoic acid function. Indeed, the reaction of TMA with these functional microgels leads to the in situ formation of alkoxide aluminum‐based species at the periphery of the star‐like microgels. All these functional PS microgels have been used as supports to immobilize and activate the MeDIP(2,6‐iPrPh) 2 FeCl 2 catalyst toward ethylene polymerization. High catalytic activities and polyethylene beads of spherical morphology, constituted of polyethylene chains of monomodal molar mass distribution have been obtained, thanks to the organic support. magnified image
Silicone Injection in Retinal Detachment (1970)

Silicone injection was used to treat 100 cases of retinal detachment: 68 eyes with massive preretinal retraction (MPR); 25 with a giant retinal break and MPR; and 7 with a giant retinal break, without MPR, whose posterior retinal flap could not be unrolled. Anatomically successful reattachment of the retina was obtained in six (9%) of the 68 eyes, two (8%) of the 25, and three (43%) of the 7. Improvement of visual function in these successes was equivocal. Preoperative examination, surgical techniques, and postoperative appearance of silicone are described. Recurrent retinal detachment, proliferation, and opacification of preretinal membranes around the silicone bubble, cataract formation, and corneal opacification were frequent late complications.
A Bast-like valve in the pigeon? (2009)

The first description of the presence of a utriculo-endolymphatic valve in human fetuses was given by Bast in 1928. Since then this valve-like structure is called Bast's valve. Its exact function has not yet been established. The general opinion is that it has a protective function by having the possibility to separate the superior endolymphatic compartments of the labyrinth from the inferior compartment. Phylogenetically seen birds are the first vertebrates with a cochlear duct and a distinct inferior and superior part of the labyrinth. A structure in the pigeon inner ear, resembling Bast's valve in mammals, is described.
The <i>in‐vitro</i> synthesized tomato shikimate kinase precursor is enzymatically active and is imported and processed to the mature enzyme by chloroplasts (1992)

Full-length cDNA clones encoding shikimate kinase (EC 2.7.1.71), an enzyme of the central section of the shikimate pathway, have been isolated from tomato (Lycopersicon esculentum L., cv. UC82b). The open reading frame has the capacity to encode a peptide of 300 amino acids. The in-vitro synthesized peptide catalysed the phosphorylation of shikimate thus confirming the identity of the isolated cDNA clones. The N-terminal portion of the deduced amino acid sequence resembles known chloroplast-specific transit peptides. The existence of such a transit peptide was proven by the uptake of the in-vitro synthesized peptide as well as its processing by isolated chloroplasts. Multiple sites of polyadenylation were observed in shikimate kinase mRNAs. The results of Northern and Southern blot analyses are consistent with the existence of only one shikimate kinase gene per haploid genome in tomato. These results are discussed with respect to the dual pathway hypothesis of the shikimate pathway in higher plants.
Low-temperature scanning tunneling microscope for use on artificially fabricated nanostructures (1994)

A scanning tunneling microscope (STM) has been developed, dedicated for use on artificially fabricated nanostructures at low temperatures. With this STM mesoscopic phenomena can be studied, combining the unique possibilities of scanning tunneling microscopy and artificially fabricated nanostructures for investigating the physics in this regime. The STM is vibration insensitive, has reliable coarse approach mechanisms in three dimensions, and operates at low temperatures. In order to be able to position the tip above the structure of interest, also a searching strategy has been developed. In this article we describe design and operation of the STM and demonstrate searching.
Light‐regulated promoters from <i>Synechocystis</i> PCC6803 share a consensus motif involved in photoregulation (1994)

A library of Synechocystis PCC6803 (S.6803) DNA cloned in front of the promoterless cat reporter gene of the plasmid pFF11 was used to transform S.6803 to high light-dependent resistance to chloramphenicol. In five clones harbouring a stably replicating pFF11-derived plasmid, this phenotype occurred independently of the photosystem II electron transport and resulted from the correlated increase of CAT activity level and cat mRNA accumulation. The five promoter inserts contained no Escherichia coli sigma 70 promoter element, in agreement with their lack of activity in this organism, but shared two conserved motifs. Two secondary mutations, which restored light-regulated promoter activity to an inactive mutant of the smallest insert, mapped within one of the common motifs, emphasizing the probable involvement of this element in photoregulation.
Implication of the Lymphocyte-Specific Nuclear Body Protein Sp140 in an Innate Response to Human Immunodeficiency Virus Type 1 (2002)

The viral infectivity factor (Vif) of human immunodeficiency virus type 1 (HIV-1) neutralizes an unidentified antiviral pathway that occurs only in nonpermissive (NP) cells. Using a yeast two-hybrid screen of a human lymphocyte cDNA library, we identified several potential Vif partners. One, the nuclear body protein Sp140, was found specifically in all NP cells (n = 12 cell lines tested; P < or = 0.001), and HIV-1 infection induced its partial dispersal from nuclear bodies into cytosolic colocalization with Vif. Our results implicate Sp140 in a response to HIV-1 that may be related to or coordinated with the pathway that inactivates HIV-1 lacking vif.
Reduced filaggrin expression is accompanied by increased <i>Staphylococcus aureus</i> colonization of epidermal skin models (2014)

This study shows that NEMs, with FLG-KD and/or cultured in the presence of IL-31, mimic the skin of patients with atopic dermatitis in several aspects, including enhanced bacterial colonization, increased inflammatory and reduced protective responses.
Effect of Heat Treatment on Shape Memory Behavior of Ti-rich Ti&ndash;Ni Thin Films (1995)

Thin films of Ti-rich Ti–Ni were prepared by sputtering. The sputter-deposited films were annealed at three different temperatures of 773, 873 and 973 K for three different times of 1, 10 and 100 h in order to crystallize them. After the heat treatment, the shape memory behavior was examined with a thermomechanical tester. The shape memory behavior was found to be very sensitive to the annealing conditions, being different from that in bulk specimens. The martensitic and reverse martensitic transformation temperatures increased with increasing annealing temperature and time. The film annealed at 973 K for 100 h showed a single-stage shape change associated with the martensitic transformation, while the other annealed films showed a two-stage shape change associated with both the martensitic and R-phase transformations. It was found from transmission electron microscopy that the difference in the shape memory behavior between thin films and bulk specimens comes from a difference in the distribution of Ti2Ni particles. That is, fine Ti2Ni particles distribute inside the TiNi grain in the annealed films except the one annealed at 973 K for 100 h. On the other hand, the structure of the film annealed at 973 K for 100 h is similar to that normally observed in bulk specimens, where Ti2Ni particles distribute along the grain boundaries.
Characterization of Insulin, Insulin-Like Growth Factors I and II, and Growth Hormone Receptors on Human Leukemic Lymphoblasts* (1986)

Receptors for insulin, insulin-like growth factors I and II (IGF-I and IGF-II), and human GH were studied in 6 T- and 12 B-lymphoblast cell lines isolated from patients with lymphoid malignancies. These cell lines have been maintained in continuous culture with stable chromosome, immunophenotype, and enzyme characteristics for an 8- to 21-month period. Four of 6 T-cell lines expressed IGF-I, but not insulin, receptors. One T-cell line bound only insulin, and 1 T-cell line bound both hormones. Conversely, 9 of 12 B-cell lines had insulin, but not IGF-I, receptors. Two of these lines bound both hormones, and 1 line did not bind either hormone. IGF-II binding was less than 1.5%/10 million cells for all lines and was less than 1% for 13 of the 18 lines. Specific binding of GH was undetectable in all cell lines. Time, temperature, and pH dependence of peptide binding were characterized for the T-cell IGF-I receptor and the B-cell insulin receptor and were consistent with previously described models for these receptors. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the cross-linked receptors revealed an apparent mol wt greater than 300K unreduced and a 130K binding subunit after dithiothreitol reduction for both the T-cell IGF-I and the B-cell insulin receptor. These cell lines thus provided a unique opportunity for the study of growth factor receptors in fully characterized clonal populations of human lymphoblasts. We conclude that specific receptors for IGF-I and insulin are present on T- and B-lymphoblasts; divergence of these receptors appears to be a characteristic of lymphoblasts, since T-cells preferentially expressed IGF-I receptors and B-cells expressed insulin receptors; and IGF-II binding was relatively low, while specific GH binding was undetectable on both T- and B-lymphoblasts. These results suggest that insulin and IGF-I may play a role in lymphocyte differentiation and metabolism.
An ELLAM Scheme for Multidimensional Advection-Reaction Equations and Its Optimal-Order Error Estimate (2001)

We present an Eulerian--Lagrangian localized adjoint method (ELLAM) scheme for initial-boundary value problems for advection-reaction partial differential equations in multiple space dimensions. The derived numerical scheme is not subject to the Courant--Friedrichs--Lewy condition and generates accurate numerical solutions even if large time steps are used. Moreover, the scheme naturally incorporates boundary conditions into its formulation without any artificial outflow boundary conditions needed, and it conserves mass. An optimal-order error estimate is proved for the scheme. Numerical experiments are performed to verify the theoretical estimate.
Not So Unique in the Crowd: a Simple and Effective Algorithm for Anonymizing Location Data. (2014)

We study the problem of privacy in human mobility data, i.e., the re-identification risk of individuals in a trajectory dataset. We quantify the risk of being re-identified by the metric of uniqueness, the fraction of individuals in the dataset which are uniquely identifiable by a set of spatio-temporal points. We explore a human mobility dataset for more than half a million individuals over a period of one week. The location of an individual is specified every fifteen minutes. The results show that human mobility traces are highly iden-tifiable with only a few spatio-temporal points. We pro-pose a modification-based anonymization approach that is based on shorting the trajectories to reduce the risk of re-identification and information disclosure. Empirical, experi-mental results on the anonymized dataset show the decrease of uniqueness and suggest that anonymization techniques can help to improve the privacy protection and reduce pri-vacy risks, although the anonymized data cannot provide full anonymity so far. 1.
Pesticide exposure and risk for Parkinson's disease (2006)

These data support the hypothesis that exposure to pesticides may increase risk for PD. Future studies should seek to identify the specific chemicals responsible for this association.
Gibberellin Treatment Stimulates Nuclear Factor Binding to the Gibberellin Response Complex in a Barley a-Amylase Promoter (1993)

Automated scenario generation for regression testing of autonomous vehicles (2017)

Autonomous vehicles are technologically feasible and are becoming a reality. However, before they can be launched, thorough testing is necessary. In this paper, we present a novel approach to automatically generate test scenarios for regression testing of autonomous vehicle systems as a black box in a virtual simulation environment. To achieve this we focus on the problem of generating the motion of other traffic participants without loss of generality. We combine the combinatorial interaction testing approach with a simple trajectory planner as a feasibility checker to generate efficient test sets with variable coverage. The underlying constraint satisfaction problem is solved with a simple backtracking algorithm.
Time-domain coherence-gated Shack-Hartmann wavefront sensor (2011)

In the present paper we investigate the possibility of narrowing the depth range of a physical Shack - Hartmann wavefront sensor (SH-WFS) by using coherence gating. We have already demonstrated a low coherence interferometry (LCI) set-up, capable of generating similar spots patterns as a conventional SH-WFS and also capable of eliminating stray reflections. Here, we evaluate the accuracy of wavefront measurements using a coherence-gated (CG)/SH-WFS. This is based on a Mach-Zehnder interferometer combined with a SH-WFS, that implements time-domain (TD)-LCI acquisition. The wavefront measurement errors introduced by the non-uniform distribution of the reference power over the photo-detector array were investigated. The effect on the centroid nodes accuracy due to different numbers of phaseshifting interferometry (PSI) steps applied was also evaluated. This novel technique has the potential of providing depth resolved aberration information, which can guide better correction in adaptive optics assisted OCT and confocal imaging instruments.
Radiofrequency ablation or percutaneous ethanol injection for the treatment of liver tumors (2012)

The liver is a common location of both primary and secondary malignancies. For unresectable liver cancer, many local ablative therapies have been developed. These include e.g., percutaneous ethanol injection (PEI), percutaneous acetic acid injection, radiofrequency ablation (RFA), cryoablation, microwave ablation, laser-induced thermotherapy, and high-intensity focused ultrasound. RFA has recently gained interest and is the most widely applied thermoablative technique. RFA allows more effective tumor control in fewer treatment sessions compared with PEI, but with a higher rate of complications. However, there are certain circumstances where PEI therapy represents a better strategy to control liver tumors than RFA, especially in situations where RFA is difficult, for example when large vessels surround the tumor. In the context of hepatocellular carcinoma (HCC), both RFA and PEI are feasible and of benefit in non-operable patients. RFA seems superior to PEI in HCC > 2 cm, and the combination of interventions may be of benefit in selected patients. Liver resection is superior to RFA for patients with HCC meeting the Milan criteria, but RFA can be employed in tumors ≤ 3 cm and where there is an increased expected operative mortality. In addition, some lines of evidence indicate that RFA and PEI can be employed as a bridge to liver transplantation. The use of RFA in colorectal liver metastases is currently limited to unresectable disease and for patients unfit for surgery. The aim of this article is to summarize the current status of RFA in the management of liver tumors and compare it to the cheap and readily available technique of PEI.
Energy Harvesting and Storage with Lithium-Ion Thermogalvanic Cells (2011)

Thermogalvanic cells (electrochemical cells under a temperature gradient) are presented as multifunctional power sources, having capabilities for both energy harvesting and energy storage. A symmetric thermogalvanic cell with lithium-ion electrodes has the ability to be charged under a temperature gradient and then discharged when the temperature gradient is removed. Presented here is the first demonstration of a cycled thermogalvanic energy storage cell. Experimental results for dE/dT (the cell voltage produced per degree temperature difference) are given for symmetric thermogalvanic cells with single-phase LixTiS2 or amorphous LixV2O5 electrodes and alkyl carbonate electrolyte solutions. All cells exhibit dE/dT on the order of 1 mV/K. The thermoelectric Seebeck coefficient of the electrode materials and extent of lithium intercalation (x) have slight or negligible effects on thermogalvanic dE/dT. There are slight dependences of dE/dT on the electrolyte anion (PF6 − vs BF4 −) and electrolyte concentration, and there is no dependence on the electrolyte solvent (EC:DMC vs PC).
Design, Synthesis, and Structure−Activity Relationships of Novel Non-Imidazole Histamine H<sub>3</sub> Receptor Antagonists (2000)

Novel, potent, and selective non-imidazole histamine H(3) receptor antagonists have been prepared based on the low-affinity ligand dimaprit (pK(I) 7.32 +/- 0.12, pK(B) 5.93 +/- 0.17). Detailed structure-activity studies have revealed that N-(4-chlorobenzyl)-N-(6-pyrrolidin-1-ylhexyl)guanidine (pK(I) 8.38 +/- 0.21, pK(B) 8.39 +/- 0.13), 30, and N-(4-chlorobenzyl)-N-(7-pyrrolidin-1-ylheptyl)guanidine (pK(I) 8.78 +/- 0.12, pK(B) 8.38 +/- 0.10), 31, exhibit high affinity for the histamine H(3) receptor. Antagonists 30 and 31 demonstrate significant selectivity over the other histamine, H(1) and H(2), receptor subtypes and a 100-fold selectivity in the sigma(1) binding assay. Compounds 30and 31 are the most potent, selective non-imidazole histamine H(3) receptor antagonists reported in the literature to date.
