Selenium and silicon delta-doping properties of GaAs by atmospheric pressure metalorganic chemical vapor deposition (1990)

We investigate selenium and silicon delta-doping characteristics for GaAs layers grown by atmospheric pressure metalorganic chemical vapor deposition. Broadened capacitance-voltage (C-V) profiles and low doping activities are found in case of Se delta doping. In contrast, excellent delta-doping characteristics result for silicon. The obtained C-V full width at half maximum are in the range of 44–49 Å for samples even with substrate temperatures of 700–750 °C, which are relatively high compared with the molecular-beam epitaxy (MBE) substrate temperature. Hall mobility measurements show the mobility enhancement due to a screening of impurity charges. Also, Shubnikov–de Haas oscillations demonstrate the two-dimensional nature of electrons confined in the delta-doped layers. Therefore, our delta-doped layers show no substantial differences in quality with MBE-grown delta-doped layers. In addition, preliminary delta field-effect transistors having a gate length of 1.5 μm and a gate width of 300 μm are fabricated.

Synthesis and Characterization of Thiophene-Containing Naphthalene Diimide n-Type Copolymers for OFET Applications (2010)

Naphthalene diimide (NDI) copolymers are attractive n-type materials for use in organic electronic devices. Four highly soluble NDI polymers are presented—each differing only in the thiophene content comprising the material. Electron mobilities as high as 0.076 cm2 V−1 s−1 for the novel material PNDI-3Th are reported. Polymer crystallinity and general macromolecular order are shown to effectively improve by increasing the number of thiophene units within the polymer backbone. The structure−property relationship of NDI−thiophene copolymers is presented and discussed as it pertains to organic field effect transistor (OFET) performance.
Nanopatterning of Recombinant Proteins Using Block Copolymer Templates (2006)

Exploiting the microphase separation of block copolymers is a facile method of synthesizing nanometer-sized structures. The interactions of recombinant proteins with block copolymer surfaces displaying nanoscale order could be used to investigate intercellular signaling and for creating arrays of nanoreactors for lab-on-a-chip applications. A block copolymer of norbornene and norbornenedicarboxylic acid (NOR/NORCOOH) was synthesized and its hydrophilic block loaded with metal ions. Protein binding ability was examined by exposing the metal-loaded copolymer film to histidine-tagged green fluorescent protein (hisGFP), washing with detergent to remove nonspecifically bound protein, and measuring the surface fluorescence. Results showed that nickel ions on the copolymer surface had superior hisGFP binding ability to copper and iron. Further investigation comparing the binding of hisGFP and GFP lacking the histidine tag showed that the nickel templated block copolymer was binding only hisGFP. It was concluded that the chelation between nickel on the polymer surface and histidine groups on the protein is the only significant binding force in the hisGFP−copolymer system.

The expression of GIPR in vasculature endothelial cell in transplanted islets (2010)

Objective:To investigate the expression of GIPR in vasculature endothelial cells in transplanted islets.Methods:Pancreas of SD rat were digested by collagenase V after the common bile ductal injection of collagenase V.Islets were purified by Ficoll discontinuous density gradient-centrifugation.Then the high-quality islets were immediately transplanted intraportally into the liver of recipient SD rats with streptozotocin-induced diabetes.The recipient rats were randomly devided into 4 groups based on time points that recipients were killed:group A(7 days)、group B(14 days)、group C(40 days),and group D(60 days).The immunosuppressive tacrolimus(FK506)and mycophenolate mofeti(lMMF)were administered to recipients by intragastric administration aftertransplantation.Concentrations of blood glucose in recipient were determined with monitor .The groups were respectively killed at different time points,then islet grafts and the expression of GIPR in vasculature endothelial cells were observed morphologically.Results:GIPR was found to be expressed in parts of the microvascular endothelial cells,Conclusion:GIPR-positive endothelial cells take part in microvascular reconstruction in islet grafts.The neogenetic islet endothelial cells might acquire some common characteristics with those of liver.
Development and Validation of a Nonisotopic Immunoassay for the Detection of LSD in Human Urine (1996)

A microplate enzyme immunoassay (EIA) for the detection of lysergic acid diethylamide (LSD) in human urine was developed. The assay kit is designed around an LSD derivative coated on the wall of microplate wells with preservatives and stabilizers. Sample and rabbit anti-LSD are added to the microplate well. The immobilized LSD and LSD present in specimens compete for the opportunity to bind to the anti-LSD antibodies. An anti-rabbit antibody labeled with horseradish peroxidase is used to provide the assay signal, which is inversely proportional to the concentration of LSD in the sample. The assay requires a 25-microL urine sample and three consecutive incubation periods of 60, 30, and 30 min at room temperature. The assay was tested with a variety of drugs, including ergot alkaloids spiked into drug-free urine at up to 100,000 ng/mL without cross-reaction. Nor-LSD was shown to cross-react between 16% and 28%, depending on its concentration. Of the other compounds tested, only ergonovine demonstrated slight cross-reactivity at approximately 0.0008%. The assay is designed to be used with a qualitative cutoff of 0.5 ng/mL. Precision testing at 0.5 ng/mL gave a coefficient of variation (CV) of 6% based on 20 replicates. The CV at 0.375 ng/mL (cutoff, -25%) was 5.2% and at 0.625 ng/mL was 6.6%. Precision at other concentrations within the range of the calibration curve gave similar results both intra- and interassay. Clinical performance of the assay was compared with that of a commercial radioimmunoassay (RIA). Comparable performance was observed with both methods, each screening a total of 458 samples as negative and 17 samples as positive relative to a 0.5 ng/mL cutoff. The EIA found an additional three positive samples that were negative by RIA. The EIA is suitable for the screening of urine samples for the presence of LSD. Preliminary indications are that the assay is also suitable for use with whole blood specimens. The assay can be performed manually or be fully automated and without the need for radioactivity; it can be used in any laboratory.

Immunological (1969)

The rejection of primary allografts is classically thought to depend on a form of cellular immunity which resembles delayed hypersensitivity. The site and mechanism of sensitization of effector cells varies with the type of graft. Recent studies suggest that humoral antibodies also play a role in rejection of certain primary allografts such as in patients who have had transfusions or multiple pregnancies.
Co‐operative action of calcium ions in transmitter release at the neuromuscular junction (1967)

1. The quantitative dependence of transmitter release on external calcium concentration has been studied at the frog neuromuscular junction, using intracellular recording and taking the amplitude of the end-plate potential (e.p.p.) as an index of the number of packets released.2. The relation between [Ca] and the e.p.p. is highly non-linear. The initial part of this relation on double logarithmic co-ordinates gives a straight line with a slope of nearly four (mean 3.78 +/- 0.2 S.D. in 28 experiments). Addition of a constant amount of Mg reduces the e.p.p. without altering the slope of the log e.p.p./log Ca relation.3. The slope of this logarithmic relation diminishes as [Ca] is raised towards the normal level.4. The results are explained quantitatively on the hypothesis that Ca ions combine with a specific site X on the nerve terminal forming CaX, and that the number of packets of acetylcholine released is proportional to the fourth power of [CaX].5. The analysis suggests that a co-operative action of about four calcium ions is necessary for the release of each quantal packet of transmitter by the nerve impulse.
A new approach for measurement of the torque-speed characteristics of induction motors (1989)

The authors present a new measurement technique for the determination of the torque-speed characteristics of induction motors. This technique is in compliance with the IEEE standard test procedure for polyphase induction motors and generators. The basic principle of this new approach consists of three main steps. The first is dynamic measurement of the speed as a function of time. The second is digital filtering of the raw speed data. Finally, the speed signal is numerically differentiated to obtain the acceleration from which the torque of the machine can be found. Experimental tests using two 20 HP induction motors confirmed that this approach is more advantageous than other methods. Also, the method produces accurate results over the full speed range of the machine in contrast to some other methods.
Development of Photocatalytic Active TiO<sub>2</sub> Surfaces by Thermal Spraying of Nanopowders (2008)

Titanium dioxide is a very useful photocatalyst for the decomposition and diminution of environmental water and air pollutants. In such applications, it can be used as slurry or as immobilized coating obtained by different deposition methods. The studies performed in the last years showed that thermal spraying could be employed to elaborate TiO 2 coatings with high performance for the decomposition of organic compounds. This manuscript presents a comparative study on the microstructure and photocatalytic performance of titania coatings obtained by different thermal spray techniques: atmospheric plasma spraying (APS), suspension plasma spraying (SPS) and high‐velocity oxygen fuel spray process (HVOF). Different titania powders and suspensions were used to study the influence of the feedstock materials on the coating characteristics. The deposits were mainly characterised by SEM and X‐ray diffraction. The photocatalytic performance was evaluated from the removal of nitrogen oxides. The experimental results showed that a drastic reduction of the pollutant concentration was obtained in presence of coatings elaborated by suspension plasma spraying. TiO 2 coatings resulting from the spraying of agglomerated powder presentd less efficiency. That was mainly explained by the significant phase transformation from anatase to rutile that occurred in the enthalpic source during the spray processes.
Prophylactic intravenous immunoglobulin in HIV-infected children with CD4+ counts of 0.20 x 10(9)/L or more. Effect on viral, opportunistic, and bacterial infections. The National Institute of Child Health and Human Development Intravenous Immunoglobulin Clinical Trial Study Group (1992)

Beneficial effect of IVIG was seen across multiple infectious outcome measures, with reductions in serious and minor viral and bacterial infections observed in children with entry CD4+ counts of at least 0.20 x 10(9)/L.
Presurgical evaluation for partial epilepsy (1990)

One hundred fifty-three patients with medically refractory partial epilepsy underwent chronic stereotactic depth-electrode EEG (SEEG) evaluations after being studied by positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) and scalp-sphenoidal EEG telemetry. We carried out retrospective standardized reviews of local cerebral metabolism and scalp-sphenoidal ictal onsets to determine when SEEG recordings revealed additional useful information. FDG-PET localization was misleading in only 3 patients with temporal lobe SEEG ictal onsets for whom extratemporal or contralateral hypometabolism could be attributed to obvious nonepileptic structural defects. Two patients with predominantly temporal hypometabolism may have had frontal epileptogenic regions, but ultimate localization remains uncertain. Scalp-sphenoidal ictal onsets were misleading in 5 patients. For 37 patients with congruent focal scalp-sphenoidal ictal onsets and temporal hypometabolic zones, SEEG recordings never demonstrated extratemporal or contralateral epileptogenic regions; however, 3 of these patients had nondiagnostic SEEG evaluations. The results of subsequent subdural grid recordings indicated that at least 1 of these patients may have been denied beneficial surgery as a result of an equivocal SEEG evaluation. Weighing risks and benefits, it is concluded that anterior temporal lobectomy is justified without chronic intracranial recording when specific criteria for focal scalp-sphenoidal ictal EEG onsets are met, localized hypometabolism predominantly involves the same temporal lobe, and no other conflicting information has been obtained from additional tests of focal functional deficit, structural imaging, or seizure semiology.
Shortest path by approximation in logic programs (1992)

An approximation paradigm is proposed for logic programming as a simple modification to a complete evaluation strategy. The motivational example illustrates how a straigthforward transformation of a declarative specification of the distance between two vertices in a directed graph leads to sophisticated algorithms for computing shortest paths. The goal of the work presented in this paper is not to provide a more efficient computation of shortest paths but to investigate how the intermediate tables, known as extension tables, generated by the complete evaluation strategy might be used in approximation algorithms. We present the ET distance algorithm in perspective, its execution is compared to those of Dijkstra's single-source and Floyd's all-pairs shortest path algorithms.
Highly Specific and Convenient Color Reaction for Methylenedioxymethamphetamine and Related Drugs Using Chromotropic Acid. Application as a Drug Screening Test (1999)

The color reaction of various drugs with chromotropic acid and sulfuric acid was examined. Methylenedioxymethamphetamine (MDMA) exhibited a red-violet color on treatment of an aqueous solution with sulfuric acid and chromotropic acid. The specificity of the reaction was examined using 65 drugs. The results showed that while related drugs with a methylenedioxyphenyl moiety, such as methylenedioxy-amphetamine and -N-ethylamphetamine, were all positive, 51 drugs including amphetamine, methamphetamine, opiates, cocaine, and phencyclidine were negative. The drugs exhibiting a positive reaction include tetrahydrocannabinol and related drugs, sulfur-containing drugs such as phenothiazine tranquilizers, and diphenhydramine. These results indicate that the present method is highly specific for MDMA and related drugs although its specificity is not absolute. The detection of MDMA in urine was investigated, and found to be possible using this method.
The Eukaryotic-Like Ser/Thr Kinase PrkC Regulates the Essential WalRK Two-Component System in Bacillus subtilis (2015)

Most bacteria contain both eukaryotic-like Ser/Thr kinases (eSTKs) and eukaryotic-like Ser/Thr phosphatases (eSTPs). Their role in bacterial physiology is not currently well understood in large part because the conditions where the eSTKs are active are generally not known. However, all sequenced Gram-positive bacteria have a highly conserved eSTK with extracellular PASTA repeats that bind cell wall derived muropeptides. Here, we report that in the Gram-positive bacterium Bacillus subtilis, the PASTA-containing eSTK PrkC and its cognate eSTP PrpC converge with the essential WalRK two-component system to regulate WalR regulon genes involved in cell wall metabolism. By continuously monitoring gene expression throughout growth, we consistently find a large PrkC-dependent effect on expression of several different WalR regulon genes in early stationary phase, including both those that are activated by WalR (yocH) as well as those that are repressed (iseA, pdaC). We demonstrate that PrkC phosphorylates WalR in vitro and in vivo on a single Thr residue located in the receiver domain. Although the phosphorylated region of the receiver domain is highly conserved among several B. subtilis response regulators, PrkC displays specificity for WalR in vitro. Consistently, strains expressing a nonphosphorylatable WalR point mutant strongly reduce both PrkC dependent activation and repression of yocH, iseA, and pdaC. This suggests a model where the eSTK PrkC regulates the essential WalRK two-component signaling system by direct phosphorylation of WalR Thr101, resulting in the regulation of WalR regulon genes involved in cell wall metabolism in stationary phase. As both the eSTK PrkC and the essential WalRK two-component system are highly conserved in Gram-positive bacteria, these results may be applicable to further understanding the role of eSTKs in Gram-positive physiology and cell wall metabolism.
Comparison Study of Different Perfusion Parameter Maps in the Evaluation of Cerebral Ischemic Lesions (2003)

Objective To compare different parameter maps (AC,area under curve,PT,time to peak,MTT,mean transit time,and RF,relative flow) of CT perfusion imaging of cerebral ischemic lesions. Methods CT perfusion images of 84 cases were analyzed retrospectively,including 18 acute ischemic stroke patients without carotid occlusive disease,21 cases of carotid occlusive disease,12 cases of moyamoya disease,33 cases of ischemic lesions after the intracranial operation. Sensitivity and conspicuity of regular CT images,AC,PT,MTT,RF were compared by two experienced neuroradiologists. Results Regular CT images of 84 patients detected 78 infarctions,and 10 patients with negative finding on regular CT images,while CT perfusion imaging detected more and larger ischemic lesions than regular CT images, P 0.01 with χ 2 test. There was no significant difference among lesion areas of AC,PT,MTT,RF images of 18 acute ischemic stroke patients without carotid occlusive disease and 33 of ischemic lesions with the intracranial operation.In 21 cases of carotid occlusive disease and 12 cases of Moyamoya,8/34 lesions on PT and MTT images were clearer than on RF images, P 0.01. Conclusion Combination of different perfusion parameter maps is useful for more correct analysis of cerebral hemodynamic status.
Role of lymphocytes in heart disease. (1998)

To the Editor: 

Recently, Ommen et al1 published in Circulation a very important observation: that relative lymphocyte concentration could be a prognostic marker in patients with symptomatic heart failure. I would like to add something about the importance of the cellular immune system in cardiovascular disease. I have shown that in acute myocardial infarction (AMI), a low CD4/CD8 ratio and low CD4 cell count on the first day of AMI strongly correlated with low ejection fraction and …
Expression and Androgenic Regulation of Human Prostate‐Specific Kallikreins (1995)

In vitro studies suggest that the protease activity of PSA might play a functional role to facilitate the growth and spreading of cancerous prostatic cells. hK2 may have similar properties. Further investigation to prove their in vivo effects is required. Regulation of PSA and hKLK2 gene expression is mediated not only by androgens, but also by a number of autocrine and paracrine factors, suggesting that the control mechanisms for expression of these genes are complex and multifaceted. Such factors may also be integral for the growth and differentiation of prostate cells. Thus PSA and hKLK2 may serve as useful markers to study the regulation of gene expression during cell growth and differentiation of the prostate.
