Antioxidative and Cytotoxic Effect of the Extract from Camellia nitidissima Chi. (2011)

Introduction: Camellia nitidissima Chi. leaves or yellow camellia is a traditional Chinese herb called “Jin Hua Cha” in Chinese medicine. It is commonly used for the treatment of liver diseases, faucitis, diarrhea, edema, hypertension, and tumor. This study aimed to investigate the antioxidative and cytotoxic effects of the extracts from Camellia nitidissima Chi. leaves. Materials and Method: Dried Camellia nitidissima Chi. leaves were extracted with 70% ethanol (F1), then further extracted with 40-60% petroleum ether (F2), ethyl acetate (F3), n-Butanol (F4) and water (F5) individually to obtain 5 fractions. The plant extracts were determined for antioxidative activity by DPPH assay, and cytotoxicity effect to HepG2 hepatoma cell line by MTT assay. Results: The results demonstrated the different potency of action among the different extracts. The F5 (water fraction) had notable anti-oxidative potential with EC50 of 63.31 ppm. Based on the lowest IC50 at 184.0 µg/ml of F4 (n -butanol fraction) this fraction should be further studied for anti-cancer activity. Conclusion: The antioxidant properties and cytotoxicity to a HepG2 hepatoma cell line of Camellia nitidissima Chi. leave extracts were studied. However, further studies should consider identifying related mechanisms, effcacy of action, and safety for use.
Effects of chemical surface treatments on the generation of AC surface photovoltages in p-type silicon wafers (1990)

The AC surface photovoltage (SPV) is generated in p-type silicon wafers treated by aqueous hydrofluoric acid (HF) dipping and an alkaline rinse. Very soon after the HF dipping, the wafer surface is found to be strongly inverted due to a large positive charge. The observed AC SPVS in the HF dipped p-type Si wafer decrease as the time of exposure to air increases, showing a reverse S-shaped curve and inflection points which correspond to the layer by layer growth of the native oxide. The alkaline rinse generates relatively low AC SPVS, implying small positive charge on the p-type Si wafer. The AC SPVS in both cases decrease because positive fixed oxide charge decreases as the native oxide grows after the HF dipping and negative charge possibly neutralises the positive fixed oxide charge after the alkaline rinse.
Equivalent design representations and transformations for interactive scheduling (1992)

High-level synthesis (HLS) requires more designer interaction to better meet the needs of experienced designers. However, attempts to create a highly interactive synthesis process are hampered by incompatibility of various representations used during synthesis. To overcome this problem, equivalent representations are needed, as well as equivalence-preserving synthesis transformations. We present the Structured Finite State Machine (SFSM) design model for scheduled behavior, show its equivalence to the Control/Data Flow Graph (CDFG) model, and define primitive behavior-preserving transformations for scheduling. We have integrated this model and these transjormations into the BIF interactive environment to enable manual rescheduling of a design.
Use of Ultraviolet Energy to Degrade Aflatoxin M1 in Raw or Heated Milk with and Without Added Peroxide (1986)

Raw whole milk was artificially contaminated to contain 1 ppb aflatoxin M1. A thin layer of milk (.1 cm) was irradiated with ultraviolet energy. In the first experiment, milk was held at 90 degrees C for 10 min, cooled to 20 degrees C, and irradiated for 30 min. Amount of aflatoxin M1 decreased equally (56.2 vs. 53.9%) in raw or preheated milk, suggesting no involvement of milk enzymes in degrading aflatoxin M1 by ultraviolet energy. Data obtained when raw milk containing aflatoxin M1 was exposed to ultraviolet energy for 15 to 60 min suggest first order kinetics for the degradation reaction. In another experiment, milk was held at 5, 25, or 65 degrees C while it was being irradiated. Aflatoxin M1 was degraded at all temperatures. Amount of toxin decreased nonlinearly when temperature at which milk was held was increased. Presence in milk of benzoyl peroxide at .002% did not change the extent to which aflatoxin M1 was degraded by irradiation. Amount of toxin, however, decreased by 89.1% in milk containing .05% H2O2 as compared with 60.7% for H2O2-free milk when both were exposed to ultraviolet irradiation for 20 min at 25 degrees C.
Degradation of Human Factor X by Human Polymorphonuclear Leucocyte Cathepsin G and Elastase (1991)

Cathepsin G and elastase from human polymorphonuclear leucocytes were used in vitro to digest human factor X. Clotting assays showed that both proteinases affected a rapid loss in the coagulant activity of factor X. Calcium ions almost totally protected the coagulant activity of factor X against the action of cathepsin G but not elastase. Polyacrylamide gel electrophoresis (in nonreducing conditions and in the presence of SDS) indicated that the proteolytic action of cathepsin G led to the removal of a peptide of low molecular mass (pX) with the consequent formation of a single stable high molecular mass product (PX). SDS electrophoresis (under reducing conditions and in the presence of SDS) indicated that a pX was derived from the light chain of factor X. The proteolytic action of elastase led to the formation of numerous degradation products. Analysis of the products generated by the action of cathepsin G indicated that cathepsin G cleaved position Phe40:Trp41 in the light chain of factor X. In the presence of citrated plasma, cathepsin G but not elastase, was responsible for a loss in coagulant activity.
Scalable Multicast Key Distribution (1994)

Multicasting is becoming an increasingly important and desired form of communication on the Internet, not surprisingly because its typical applications include audioand video conferencing [4]. Providing security services, such as traffic confidentiality, for multicast communication is particularly problematic, since it involves securely distributing a group key to each of a group&apos;s receivers. Traditionally, the key distribution function has been assigned to a central network entity, or Key Distribution Centre (KDC), but this method does not scale for wide-area multicasting, where group members may be widely-distributed across the internetwork, and a wide-area group may be densely populated. No effective solution to this problem has been proposed to date. This paper addresses the multicast key distribution problem and provides a scalable solution.

Evaluation of Isomeric Sodium Alkenesulfonates via Methylation and Gas Chromatography (1969)

Volatile derivaties have been prepared for isomers of alpha olefin derived sodium alkenesulfonates, and their separation by gas chromatography has been achieved. A nonaqueous cation exchange or a direct acidification step served to convert the sodium salts to sulfonic acids; methylation using diazomethane yielded volatile methyl sulfonate derivatives. The preparation and resolution of vicinal positioned isomers of model type sodium hexadecene-1 sulfonates is presented. Mass spectrometry data confirmed the amenability of these products to undergo methylation.
Designing Microstructural Architectures With Thermally Actuated Properties Using Freedom, Actuation, and Constraint Topologies (2013)

In this paper, we demonstrate how the principles of the freedom, actuation, and constraint topologies (FACT) approach may be applied to the synthesis, analysis, and optimization of microstructural architectures that possess extreme or unusual thermal expansion properties (e.g., zero or large negative-thermal expansion coefficients). FACT provides designers with a comprehensive library of geometric shapes, which may be used to visualize the regions wherein various microstructural elements can be placed for achieving desired bulk material properties. In this way, designers can rapidly consider and compare a multiplicity of microstructural concepts that satisfy the desired design requirements before selecting the final concept. A complementary analytical tool is also provided to help designers rapidly calculate and optimize the desired thermal properties of the microstructural concepts that are generated using FACT. As a case study, this tool is used to calculate the negative-thermal expansion coefficient of a microstructural architecture synthesized using FACT. The result of this calculation is verified using a finite element analysis (FEA) package called ale3d.
Partial purification of a glucocorticoid receptor. (1975)

A simple method for purification of the glucocorticoid receptor from hepatoma tissue culture cells has been developed. The procedure, which requires only about 24 hr, involves biospecific adsorption of the receptor to deoxycorticosterone derivatized agarose, elution with a glucocorticoid, and gel filtration. The receptor-steroid complex is obtained in 35-40% yield and is about 2000-fold purified. It possesses properties similar to those reported in crude extracts, including sedimentation coefficient in glycerol gradients and activation-dependent binding to nuclei.

Surgical Progress (1984)

Myocardial recovery during reperfusion following ischemia is critical to patient survival in a broad spectrum of clinical settings. Myocardial functional recovery following ischemia correlates well with recovery of myocardial adenosine triphosphate (ATP). Adenosine triphosphate recovery is uniformly incomplete during reperfusion following moderate ischemic injury and is therefore subject to manipulation by metabolic intervention. By definition ATP recovery is limited either by (1) energy availability and application in the phosphorylation of adenosine monophosphate (AMP) to ATP or (2) availability of AMP for this conversion. Experimental data suggest that substrate energy and the mechanisms required for its application in the creation of high energy phosphate bonds (AMP conversion to ATP) are more than adequate during reperfusion following moderate ischemic injury. Adenosine monophosphate availability, however, is inadequate following ischemia due to loss of diffusable adenine nucleotide purine metabolites. These purine precursors are necessary to fuel adenine nucleotide salvage pathways. Metabolic interventions that enhance AMP recovery rather than those that improve substrate energy availability during reperfusion are therefore recommended. The mechanisms of various metabolic interventions are discussed in this framework along with the rationale for or against their clinical application.
APPLICATION OF A REAL-TIME CONTROL STRATEGY FOR BAYESIAN BELIEF NETWORKS TO SHIP CLASSIFICATION PROBLEM SOLVING (1993)

Many classification problems must be performed in a timely or time constrained manner. For this reason, the generation of control schemes which are capable of responding in real-time are fundamental to many applications. For our problem, that of ship classification, tactical scenarios often dictate the response time required from a system. In this paper, we discuss efficient ways to prioritize and gather evidence within belief networks. We also suggest ways in which we can structure our large problem into a series of small ones. This both pre-defines much of our control strategy into the system structure and also localizes our run-time control issues into much smaller networks. The overall control strategy thus includes the combination of both of these methods. By combining them correctly we can reduce the amount of dynamic computation required during run-time and thus improve the responsiveness of the system.
Reversible Electrochemical Generation of a Rhodium(II) Porphyrin:  Thwarting Disproportionation with Weakly Coordinating Anions (2003)

We report electrochemical generation of a stable Rh(II) porphyrin (Rh(II)(F(28)TPP)) from a four-coordinate Rh(I) precursor [Rh(I)(F(28)TPP)](-) dissolved in weakly coordinating electrolyte solutions. This work provides the first example of an unambiguously reversible one-electron electrochemical oxidation of a Rh(I)(por), and demonstrates that electrochemical oxidation can be performed under conditions that are compatible with alkane activation. These studies begin to classify those media capable of supporting a stable Rh(II)(por), and those that induce disproportionation.
Precision Magnetic Bearing Six Degree of Freedom Stage (1996)

Magnetic bearings are capable of applying force and torque to a suspended object without rigidly constraining any degrees of freedom. Additionally, the resolution of magnetic bearings is limited only by sensors and control, and not by the finish of a bearing surface. For these reasons, magnetic bearings appear to be ideal for precision wafer positioning in lithography systems. To demonstrate this capability a linear magnetic bearing has been constructed which uses variable reluctance actuators to control the motion of a 14.5 kg suspended platen in five degrees of freedom. A Lorentz type linear motor of our own design and construction is used to provide motion and position control in the sixth degree of freedom. The stage performance results verify that the positioning requirements of photolithography can be met with a system of this type. This paper describes the design, control, and performance of the linear magnetic bearing.
Development of a self-fertile ditelosomic line for the long arm of chromosome 4B and its characterization using SSR markers (2013)

The ditelosomic line for the long arm of chromosome 4B (4BL) of Chinese Spring (CS) wheat is not available because it is completely male sterile. Since all deletions in the 4B short arm (4BS) cause male sterility in the homozygous condition, a male-fertility gene should be located in a distal region of 4BS. Among the selfed progeny of a hybrid between a male-sterile 4BS deletion plant (4BS-8) and a Japanese common wheat cultivar Norin 61 (N61), we obtained self-fertile 4BS-8 homozygous deletion plants. We also found fertile nullisomic-4B plants among the selfed progeny of a hybrid between a monosomic line 4B of N61 and CS. This fact suggested that N61 has a novel male-fertility gene on a chromosome other than 4B. We established a self-fertile ditelosomic 4BL line after backcrossing a fertile 4BS-8 plant to CS monotelodisomic 4BL. By cytological observation and PCR analysis using 16 SSR markers, we verified that this ditelosomic line lacked the entire 4BS arm and found that three of the markers were on 4BS. We conducted deletion mapping using three 4BS homozygous deletion lines and three 4BS-specific markers.
The role of extended-release benzodiazepines in the treatment of anxiety: a risk-benefit evaluation with a focus on extended-release alprazolam. (2002)

Immediate-release (IR) benzodiazepines have a short duration of therapeutic effect and are generally less effective for anxiety than selective serotonin reuptake inhibitors in reducing concomitant depressive symptomatology. Common criticisms of benzodiazepines also include the patient's tendency to develop a tolerance to the anxiolytic effect and a dependence on the drug itself. The newer extended-release (XR) benzodiazepine formulation was designed to increase efficacy, duration of therapeutic effect, tolerance, compliance, and ease of discontinuation. The XR benzodiazepine alprazolam has shown efficacy in panic disorder and generalized anxiety disorder comparable to the older benzodiazepine formulations. Pharmacokinetic data show that the XR formulation has a longer therapeutic effect compared with IR formulations, which reduces the potential for breakthrough anxiety symptoms. Data also indicate that the XR formulation has less abuse liability than the IR formulation. This article reviews the efficacy, safety, and discontinuation data from clinical trials of IR and XR benzodiazepines in the treatment of anxiety disorders and provides guidelines to minimize the risk of withdrawal syndrome during benzodiazepine discontinuation.
[Changes in the brain spontaneous bioelectrical activity during transcranial electrical and electromagnetic stimulation]. (2006)

In order to study systemic brain reactions on transcranial electrical or electromagnetic medical stimulation and specify the neurophysiological criteria of its efficiency, comparative clinical and experimental examination was performed with the analysis of spontaneous bioelectric activity and behavioral or clinical parameters. We examined 6 patients with prolonged posttraumatic unconsciousness states treated with electrical stimulation and 17 intact Wistar rats subjected to electromagnetic stimulation of the brain. The effect of the transcranial stimulation was shown to depend on the initial level of the intercentral interactions of brain bioelectrical activity, estimated by the EEG coherence. Hypersynchronization of biopotentials as the main element of the brain reactivity can be the most useful for the rehabilitation of patients with cerebral pathology in cases of initially lowered level of the intercentral interactions in the absence of pathologically strengthened functional connections.

Images as mediating texts in annual reports: the case of China Mobile (2012)

Purpose: This study explores the dual ideological influences that the socialist political regime and the globalised market economy have on the visual images in accounting annual reports in the Chinese context. It also investigates how the visual discourse, in turn, constitutes and sustains competing ideological messages.\nDesign/Methodology/approach: Based on the 2010 annual report of China Mobile Limited, A critical discourse analysis is conducted at three levels. At the public discourse level, three areas of interest are drawn in interpreting the connotations of the visual discourse, including (1) Davison's (2010) rhetorical codes (physical, dress, spatial, and interpersonal); (2) two Chinese cultural beliefs (Confucianism and Taoism); and, (3) the socio-political cognition of colour. At the social practice level, the political and financial structure of China Mobile is examined. Finally, the discourse practice analysis investigates the discursive process in which the annual report is produced, distributed and consumed by different reader groups.\nFindings: The study finds that visual discourse in annual reports constitutes and sustains competing ideological messages. The competing connotations are then mediated and naturalised through juxtaposing image with different context in which the annual report is put forward.\nOriginality/value: The application of Critical Discourse Analysis provides a useful framework for future studies of visual images in annual reports. The conflation of Davison's (2010) rhetorical codes, the Chinese cultural beliefs, and the cognition of colour adds to the understanding of the socio-political significance of visual discourse in accounting.
Multi-scale sub-image search (1999)

If an image should be retrieved by its subregions from a large image database, an immense number of possible queries will appear. Therefore, the index which encodes the spatial information of an image, should make only few assumptions about possible queries. In addition, this index has to consider different scales of objects in the image. In this paper, we propose a novel approach using a hierarchical index encoding image regions, gained by a fixed partition.
Biofouling Prevention Technologies for Coastal Sensors/Sensor Platforms (2003)

Hypoglobus following orbital decompression is not a rare complication. Hypoglobus requiring surgery to elevate the globe following orbital decompression is considered clinically significant hypoglobus. A retrospective analysis of 157 consecutive patients who had their orbits expanded by removing the medial wall and floor of the orbit found seven patients (4.5%) who required further surgery to elevate the globe. The seven patients who developed clinically significant hypoglobus following orbital decompression all developed a set of distinct clinical signs. These included a "setting sun" appearance of the globe, eyelid malposition, orbital volume loss, and strabismus. These clinical signs can be explained by the inferior movement of the globe and the orbital contents following the loss of support structures on the orbital floor. A two-wall orbital decompression performed on a cadaver reproduced the physical signs of hypoglobus. The dissection suggested that the periorbita is the most important structure supporting the globe in the orbit.
Quarter-Wavelength Coupled Variable Bandstop and Bandpass Filters Using Varactor Modes (1982)

A quarter-wavelength coupled bandstop filter rising varactor diodes for the 6-GHz band has been proposed and tested. Frequency giving maximum attenuation varies from 4.4 GHz-7 GHz. A quarter-wavelength coupled variable bandpass filter using varactor diodes for the 4-GHz band is also proposed and tested. The passband width varies from 730 MHz-1.22 GHz. The center frequency of the filter can also be changed.
