Cotton Cultivar Response to Mepiquat Chloride1 (1983)

Abstract The effects of mepiquat chloride (1,1‐dimethylpiperidinium chloride) on cotton ( Gossypium hirsutum L.) growth and yield have been widely studied but few studies have investigated cultivar response to this plant growth regulator. Since the response to a pesticide or a plant growth regulator may vary among cultivars, a knowledge of cultivar response to that chemical is an important consideration when developing recommendations for its use. A 3‐year study was conducted in eight environments to determine if 14 cultivars respond differently to mepiquat chloride. Cultivars evaluated were ‘Coker 304’, ‘Coker 310’, ‘Coker 315’, ‘Coker 420’, ‘Deltapine 41’, ‘Deltapine 55’, ‘Deltapine 70’, ‘McNair 220’, ‘McNair 235’, ‘Rex 713’, ‘SC 1’, ‘Stoneville 213’, ‘Stoneville 506’, and ‘Stoneville 825’. Mepiquat chloride at a rate of 49 g/ha increased lint yield 10 to 28% in three environments and decreased yield 5% in one environment. Earlier maturity was usually observed. Plant height was reduced 11 to 26%, and reductions in plant height were closely correlated with final height of the untreated cotton. Mepiquat chloride increased both boll weight and seed weight 3 to 10%, and slightly increased fiber length. The effect on micronaire was variable, but in most environments there was a small reduction. There was little to no effect on number of seed per boll, fiber strength, and fiber length uniformity. Lint percent was decreased 0.4 to 0.8% in most environments as a result of the increased seed weight. There were no mepiquat chloride by cultivar interactions for lint percent, fiber length, boll weight, seed weight, number of seed per boll, number of bolls produced, plant height, or maturity. Cultivar by mepiquat chloride interactions for yield, micronaire, fiber strength, and fiber length uniformity were observed in only one environment. All observed mepiquat chloride by cultivar interactions were small and, considering the infrequency of occurrence, were probably not of practical significance. This study indicated that cultivar selection should not be a consideration in deciding whether to apply mepiquat chloride.
Mammalian Secreted Phospholipases A2 and Their Pathophysiolo-gical Significance in Inflammatory Diseases (2001)

Phospholipases A2 (PLA2s) represent a growing family of enzymes that catalyze the hydrolysis of phospholipids at the sn-2 position leading to the generation of free fatty acids and lysophospholipids. Mammalian PLA2s are divided into two major classes according to their molecular mass and location: intracellular PLA2 and secreted PLA2 (sPLA2). Type-IIA sPLA2 (sPLA2-IIA), the best studied enzyme of sPLA2, plays a role in the pathogenesis of various inflammatory diseases. Conversely, sPLA2-IIA can exert beneficial action in the context of infectious diseases since recent studies have shown that this enzyme exhibits potent bactericidal effects. Induction of the synthesis of sPLA2-IIA is generally initiated by endotoxin and a limited number of cytokines via paracrine and/or autocrine processes. If the mechanisms involved in the regulation of sPLA2-IIA gene expression have been relatively clarified, little is known on the mechanisms that regulate the expression of other sPLA2. There have been substantial progresses in understanding the transcriptional regulation of sPLA2-IIA expression. Recently, transcription factors including NF-kappaB, PPAR, C/EBP have been identified to play a prominent role in the regulation of sPLA2-IIA gene expression. The activation of these transcription factors is under the control of distinct signaling pathways (PKC, cAMP ...). Accumulating evidences in the literature suggest that cytosolic PLA2 together with two sPLA2 isozymes (sPLA2-IIA and sPLA2-V) are functionally coupled with cyclooxygenase-1 and 2 pathways, respectively, for immediate and delayed PG biosynthesis. This spatio-temporal coupling of cyclooxygenase enzymes with PLA2s may represent a key mechanism in the propagation of inflammatory reaction. Unraveling the mechanisms involved in the regulation of the expression of sPLA2s is important for understanding their pathophysiological roles in inflammatory diseases.
PILOT: Practical Privacy-Preserving Indoor Localization Using OuTsourcing (2019)

In the last decade, we observed a constantly growing number of Location-Based Services (LBSs) used in indoor environments, such as for targeted advertising in shopping malls or finding nearby friends. Although privacy-preserving LBSs were addressed in the literature, there was a lack of attention to the problem of enhancing privacy of indoor localization, i.e., the process of obtaining the users' locations indoors and, thus, a prerequisite for any indoor LBS. In this work we present PILOT, the first practically efficient solution for Privacy-Preserving Indoor Localization (PPIL) that was obtained by a synergy of the research areas indoor localization and applied cryptography. We design, implement, and evaluate protocols for Wi-Fi fingerprint-based PPIL that rely on 4 different distance metrics. To save energy and network bandwidth for the mobile end devices in PPIL, we securely outsource the computations to two non-colluding semi-honest parties. Our solution mixes different secure two-party computation protocols and we design size-and depth-optimized circuits for PPIL. We construct efficient circuit building blocks that are of independent interest: Single Instruction Multiple Data (SIMD) capable oblivious access to an array with low circuit depth and selection of the k-Nearest Neighbors with small circuit size. Additionally, we reduce Received Signal Strength (RSS) values from 8 bits to 4 bits without any significant accuracy reduction. Our most efficient PPIL protocol is 553x faster than that of Li et al. (INFOCOM'14) and 500× faster than that of Ziegeldorf et al. (WiSec'14). Our implementation on commodity hardware has practical run-times of less than 1 second even for the most accurate distance metrics that we consider, and it can process more than half a million PPIL queries per day.
CSSX Radiolytic H2 Generation ("Thermolysis") -- Final Report (2009)

The purpose of this work was to determine the radiolytic hydrogen gas yield of irradiated CSSX solvent at several temperatures. The active ingredient of this solvent is calix[4]arene-bis-(t-octylbenzo) crown-6, a calixarene crown ether used for cesium complexation. The solvent also contains 1-(2,2,3,3-tetrafluoropropoxy)-3-(4-sec-butylphenoxy)-2-propanol, a fluorinated alcoholic solvent modifer used to improve the solubility of the calixarene and its cesium complex in the Isopar L diluent. Isopar L is a branch-chain alkane and comprises most of the mixture. Samples of this solution were irradiated to various absorbed ?-ray doses in gas-tight sample containers, which were then sampled for hydrogen gas content. The methods are described below.
Inferring local surface orientation from motion fields (1982)

The problem of inferring local surface orientation from changing images is studied computationally by deriving conditions under which the motion information is sufficient for an information processing system, biological or otherwise, to infer unique descriptions of the local surface orientation. The analysis is based on shape-from-motion proposition, which states, that given the first spatial derivatives of the orthographically projected velocity and acceleration fields of a rigidly rotating regular surface, then the angular velocity and the surface normal at each visible point on that surface are uniquely determined up to a reflection. The proof proceeds in two steps. First it is shown that surface tilt and one component of the angular velocity are uniquely determined by the first spatial derivatives of the velocity field. Then it is shown that surface slant and the remaining two components of the angular velocity are uniquely determined if the first spatial derivatives of the acceleration field are also available.
Large-scale use of polymerase chain reaction for detection of Mycobacterium tuberculosis in a routine mycobacteriology laboratory (1993)

We investigated the use of DNA amplification by the polymerase chain reaction reaction (PCR) for detection of Mycobacterium tuberculosis from clinical specimens. Two-thirds of each sample was processed for smear and culture by standard methods, and one-third was submitted for DNA extraction, amplification of a 317-bp segment within the insertion element IS6110, and detection by agarose gel electrophoresis, hybridization, or both. DNA was prepared from over 5,000 samples, with 623 samples being culture positive for acid-fast bacilli. Of 218 specimens that were identified as M. tuberculosis, 181 (85%) were positive by PCR. In the M. tuberculosis culture-positive group, PCR was positive for 136 of 145 (94%) and 45 of 73 (62%) of the fluorochrome smear-positive and -negative specimens, respectively. Of 948 specimens that were either culture positive for mycobacteria other than M. tuberculosis or culture negative, 937 specimens were negative by PCR and 11 (1%) specimens initially appeared to be false positive for M. tuberculosis. The reason for discrepant results varied; some errors were traced to the presence of an inhibitor in the specimen (7.3% in unselected specimens), nucleic acid contamination, low numbers of organisms in the specimen antituberculosis therapy, and possible low-level nonspecific hybridization. In comparison with culture, the sensitivity, specificity, and positive predictive value were 83.5, 99.0, and 94.2%, respectively, for PCR. When PCR was corrected for DNA contamination, the presence of inhibitor, and culture-negative disease, the values became 86.1, 99.7, and 98.4%, respectively. If the results for multiple specimens submitted from the same patient are considered, no patient who had three of more sputum specimens tested would have been misdiagnosed.

Abstract Objective: To analyze the in-hospital outcome of elderlypatients aged 70 years and older who underwent off-pumpcoronary artery bypass graft surgery with an intraluminalshunt in urgent, emergent, and elective coronaryrevascularizations. Methods: From July 1989 to July 2005, we analyzed 87patients ranging in age from 70 to 92 years. Of the 87 patientsenrolled, 50 (57.5%) patients had unstable angina, with three(3.4%) acute myocardial infarction; thirty-one (35.6%)patients underwent urgent and emergent surgery; thirteen(14.9%) patients had myocardial infarction in less than 30days, and 34 (39.1%) in more than 30 days. Results: The main postoperative complications were: atrialfibrillation (32.2%), heart failure (12.6%), pneumonia(10.3%), septicemia (3.4%), acute myocardial infarction(2.3%), mediastinitis (1.1%) transient ischemic attack(1.1%), and pneumothorax (1.1%). The mean extubationtime was 18.50±19.09 hours, the length of stay in theintensive care unit was 2.92±2.03 days, and hospital lengthof stay was 10.55±7.16 days. Packed red cells were given tonine (10.34%) patients and none of them was operated dueto bleeding. The in-hospital mortality was 4,6%.
Increase in free radicals on UHMWPE hip prostheses components due to inflamed synovial cell products (2001)

Oxidative degradation of artificial UHMWPE joint implants caused by gamma-ray sterilization is thought to be responsible for the production of wear debris resulting in adverse tissue responses. On the other hand, it is well known that inflammation is associated with generation, by inflammatory cells, of free radicals (H(2)O(2) and NO) and destructive proteolytic enzymes (collagenases), which creates a strong oxidative environment. We hypothesized that when an UHMWPE implantation was performed in an inflammatory joint environment, the oxidative substances produced by inflamed synoviocytes could increase oxidative degradation of the polyethylene insert. We measured the amount of free radicals on conventional and on Duration-treated polyethylene samples by the electron spin resonance (ESR) technique before and after exposure of the samples to (1) inflamed synovial cell cultures; (2) normal synovial cell cultures; and (3) medium alone. We observed an increase in the number of free radicals on polyethylene samples after their immersion in cell cultures. Furthermore, it was observed that the increase of free radicals on polyethylene correlated with the degree of inflammation of synovial cells in culture.
Basic : Cytochrome P450 epoxygenase 2C9 inhibitor sensitizes cancer stem cell apoptosis under hypoxia (초) (2011)

-S117 mouse albumin promoter and mouse alpha-feptoprotein enhancer are integrated. Methods: The pLive vector was cloned with SV40 T antigen gene, and then the plasmid was microinjected into pronuclearstage zygotes from C57/B6 mice. The incorporation of the transgene among progenies was evaluated using PCR, and the SV40T gene positive animals were continuously crossed with normal mice. Histological confirmation of HCC was carried out in 24 weeks old transgenic mice. Results: Multiple large tumor nodules were shown on the liver surface of the transgenic mice. In timorous tissues, poorly differentiated HCC were observed in H&E stains, AFP and Ki-67 were overexpressed in immunohistochemistry, suggesting HCC was successfully induced by SV40T antigen under organ specific promoter. Conclusion: Our study demonstrated the establishment of transgenic mouse model of HCC using SV40T gene and pLive vector system and this model could be applied to evaluate the anti-tumor efficacy of several anti-cancer drugs or target therapy in HCC.

A 3GPP 4G Evolved Packet Core-based system architecture for QoS-enabled mobile video surveillance applications (2012)

Mobile video surveillance applications have become ubiquitous and are used in both civilian and military settings. They enable the capture, storage and transmission of video images over the Internet or other networks. This paper proposes a novel system architecture for mobile video surveillance applications. We leverage the 3GPP 4G Evolved Packet Core (EPC) to enable features such as guaranteed quality of service (QoS), which is not possible with the Internet, and even differentiated QoS, which is not possible with the other networks currently used in mobile video applications. The key components of our proposed architecture are the service development platform (SDP) and the machine to machine (M2M) gateway. The SDP enables the development and management of QoS-enabled mobile video surveillance applications. The M2M gateway enables interactions with the M2M devices, such as motion detectors and cameras. We have built a prototype with the Fraunhofer Fokus OpenEPC as 3GPP 4G EPC infrastructure and three AXIS network cameras as M2M devices. The architecture is presented along with the prototype. Related work is also reviewed.
Differential Calorimeter of the Tian-Calvet Type (1958)

A differential microcalorimeter of the Tian-Calvet type has been designed and constructed. The galvanometers previously employed have been replaced by a dc amplifier, which materially simplified the construction and operation of the instrument. In addition, this allows an electrical analog integrator to be used which gives directly the heat of reaction. Sensitivity of the instrument in the range from 0.01 to 2 cal is such that measurements can be made with a precision of 1% or better. Measurements have been made, under ideal conditions, of 0.002 cal with a standard deviation of 0.1%.
Competing Endogenous RNA of Snail and Zeb1 UTR in Therapeutic Resistance of Colorectal Cancer (2021)

The epithelial-mesenchymal transition (EMT) comprises an important biological mechanism not only for cancer progression but also in the therapeutic resistance of cancer cells. While the importance of the protein abundance of EMT-inducers, such as Snail (SNAI1) and Zeb1 (ZEB1), during EMT progression is clear, the reciprocal interactions between the untranslated regions (UTRs) of EMT-inducers via a competing endogenous RNA (ceRNA) network have received little attention. In this study, we found a synchronized transcript abundance of Snail and Zeb1 mediated by a non-coding RNA network in colorectal cancer (CRC). Importantly, the <i>trans</i>-regulatory ceRNA network in the UTRs of EMT inducers is mediated by competition between tumor suppressive miRNA-34 (miR-34) and miRNA-200 (miR-200). Furthermore, the ceRNA network consisting of the UTRs of EMT inducers and tumor suppressive miRs is functional in the EMT phenotype and therapeutic resistance of colon cancer. In The Cancer Genome Atlas (TCGA) samples, we also found genome-wide ceRNA gene sets regulated by miR-34a and miR-200 in colorectal cancer. These results indicate that the ceRNA networks regulated by the reciprocal interaction between EMT gene UTRs and tumor suppressive miRs are functional in CRC progression and therapeutic resistance.
Synthesis and properties of thermoplastic expandable microspheres: The relation between crosslinking density and expandable property (2004)

Abstract A set of thermoplastic expandable microspheres was investigated with respect to their crosslinking density and expandable property. The crosslinking efficiencies of dipentaerythritol hexaacrylate in a set of thermoplastic expandable microspheres were measured. As expandable properties, expansion curves were measured by using a thermomechanical analyzer, and they also were shown by measuring the change of thickness of the coated compound consisting of ethylene–vinyl acetate copolymer resin emulsion and CaCO 3 with thermoplastic microspheres on paper. In view of the expansion ratio and heat resistance, as crosslinking density, a swelling ratio of about 20–25 is needed to achieve optimum expansion without collapse and rupture of microspheres. © 2004 Wiley Periodicals, Inc.

Static and Dynamic Beamforming with Huygens' Metasurface Antennas (2021)

Most antenna applications require certain control of the radiation characteristics, such as the direction of the beam, the directivity and the sidelobe level. It may also be desirable to steer the beam dynamically. Although control of the far-field region of antennas has been traditionally achieved by antenna arrays, the feeding networks of such arrays result in bulky designs and increase power losses. A promising alternative is the use of metasurfaces that transform the fields of a simple source to aperture fields corresponding to prescribed radiation patterns. In this paper, different ways are presented to obtain both static and dynamic beamforming with Huygens' metasurfaces.
Food safety and pharmacokinetic studies which support a zero (0) meat and milk withdrawal time for use of sometribove in dairy cows. (1990)

Sometribove (SB) is a synthetic form of bovine somatotropin (BST) whose amino acid sequence is the same for 190 of the 191 amino acids in BST. Administration of 500 mg of SB to dairy cows every 14 d increases the efficiency of milk production. Regulatory agencies have authorized a zero (0) milk and meat withdrawal time for investigational use of SB. The scientific basis for this authorization is as follows: 1) BST and other non-primate somatotropins are not active in humans, due to differences in the amino acid sequence from human somatotropin, which limits the ability of BST to bind to receptors on human tissues. 2) SB is not orally active, as it is degraded like other proteins when eaten. Administration of 50,000 microgram/kg/d SB to rats for 90 d produced no growth response. 3) Residual levels of SB in meat/milk are very low (ppb) and comparable to endogenous BST levels. 4) Residual levels (ppb) of insulin-like growth factor I (IGF-I) in meat and milk are only marginally increased by SB treatment (somatotropin stimulates local production of IGF-I in tissues to mediate some of its biological effects. 5) IGF-I was not orally active when fed to rats at doses ranging from 200 to 2,000 microgram/kg for 14 d.
Basic Staining Techniques for Cartilage Sections (2003)

Historically, growth plate (physeal) and articular cartilage have received greater attention than bone because they can be processed and sectioned more easily following paraffin and glycol methacrylate embedment and because they contain extracellular matrix (ECM) components whose interest and importance is not only confined to the skeleton.23 Histology has also played a role in defining the cell and matrix degradation that occurs in osteoarthritis and rheumatoid arthritis. Recently, there has been renewed interest in reliable and informative staining methods for articular cartilage, which can be used in the evaluation of tissue-engineered cartilage. The purpose of this chapter is to review the utility of fundamental staining procedures for cartilage specimens.
德国新《产品责任法》(待续) (1992)

1985年7月25日,欧洲共同体部长理事会颁布了《关于协调成员国有关缺陷产品责任的法律规定和行政规定的指令》。1989年11月15日,〔德国〕联邦议会通过了《产品责任法》,将《指令》变为国内法。1990年1月1日,新的《产品责任法》生效。迄今为止,在德国适用的是作为法官法形成的、以《德国民法典》(以下简称《民法典》——译者)第823条及相继条款为根据的产品制造人责任法,该法在新的《产品责任法》生效以后继续适用。新法的适用会在实践中产生一些重大的变化,但这种变化就结果而言并没有人们经常所认为的那样深刻。一、适用范围从《民法典》第823条中发展形成的、以过错为前提的制造人责任,既保护最终消费者的权益,如身体、生命、健康和所有权,同时也保护那些与制造人具有直接合同关系的营业性
Effect of rifampin on the pharmacokinetics, safety and tolerability of navitoclax (ABT-263), a dual inhibitor of Bcl-2 and Bcl-XL, in patients with cancer (2014)

Co-administration navitoclax with rifampin moderately decreased navitoclax AUC, which could be partly due to the induction effect of rifampin on CYP3A4. Further assessment on the mechanism of drug interaction is warranted.
Bell's palsy and intraocular pressure. (1975)

A prospective study was established to test the effect of orbicularis tone on intraocular pressure. Local nerve block of the 7th cranial nerve by either the methods of Van Lint or O'Brien and Atkinson revealed no effect on the measured intraocular pressure.
