  4. Millerism - an historical enigma?

    Directory of Open Access Journals (Sweden)

    1975-01-01

    Full Text Available It is a wellknown fact in history that strong bias in the writers and a wishful thinking radically prevent the analysis of any event or religious activity. For this reason Catholic ecclesiastical writers of the old school distorted the role of Martin Luther and his movement; likewise the Radical Reformation fared badly in old handbooks, whether they were composed by Catholics or Lutherans. Again the same principle applies to many of the modern "sects" in America and in Europe. Millerism is an excellent case for illustrating this unfelicitious type of writing. The layman-evangelist William Miller (1782-1849 claimed that the world would never be converted; only the second coming of Christ could usher in the millennium. In order to obtain a better understanding of Millerism, the movement should be divided into three main periods, which differed in character. At first, Miller's own development needs to be ascertained. Though he lacked any thorough intellectual training and remained an autodidact, he nevertheless belonged to the wide range of middle class Yankees. To be sure, Miller lived not too far from the famous frontier in his youth, but despite preconceived ideas in some writers, Miller had his cultural roots in the built-up areas of a New England society. The second important stratum in his personality was the warm Baptist revivalism, which prevailed in his home. Deism and revivalism thus contended for the supremacy of his soul; admitting the later dominance of evangelical revivalism, reason and order continued to hold a place in his mental set-up.

    Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    Full Text Available The tropical fruits are sensitive to low storage temperatures, so optimal parameters have been searched for storage and transport for the purpose of maintaining its overall quality as long as possible to the consumer. The effect of different storage temperatures (6, 10, 15, 21 and 27 ºC and storage durations (0 to 20 d on total phenolics and enzymatic activity of peroxidase (POD, catalase (CAT, and polyphenol oxidase (PPO on sapodilla (Achras sapota L. fruit was investigated. The extraction and quantitation of protein and phenols from fruit was performed, then the enzymatic activity of PPO, POD and CAT was determined. The concentration of total phenolics decreased in the control fruit. POD activity was 3268.7 ± 1.4 U g-1 in ripening and senescence of sapodilla stored at 27 °C. CAT activity reached a peak of 34.0 ± 0.25 U g-1 in senescence in control fruit. PPO activity remained unchanged in the ripening stage and until consumption. The best storage temperatures to prolong the post-harvest life of the sapodilla fruit were 6 °C and 10 °C when storage was at low temperatures. POD activity was inactivated during sapodilla storage at low temperatures (6 and 10 °C and after being transferred to 27 °C the activity was reactivated. Likewise of fruits stored at 21 °C after being transferred to 27 °C the POD activity was reactive with a maximum value of 46.3 ± 0.012 U g-1. Enzyme activity decreased at low temperatures, which contributed to the preservation of the fruit, showing that the cold retards the maturation processes.

    Artocarpus altilis (Parkinson) Fosberg has traditionally been used in Indonesia for the treatment of liver cirrhosis, hypertension, and diabetes. In many other countries, it is used for the treatment of malaria, yellow fever, and dengue fever. It has been reported that A. altilis extracts have antiatherosclerotic and cytoprotective effects, but its molecular targets in tumor cells are not yet fully understood. The A. altilis extracts and the partially purified fraction have been shown to inhibit STAT3 activity and the phosphorylation of STAT3 in a dose-dependent manner. To identify the active components, a bioassay-guided isolation of the partially purified fraction resulted in the identification of a geranyl dihydrochalcone, CG901. Its chemical structure was established on the basis of spectroscopic evidence and comparison with published data. The partially purified fraction and the isolated a geranyl dihydrochalcone, CG901, down-regulated the expression of STAT3 target genes, induced apoptosis in DU145 prostate cancer cells via caspase-3 and PARP degradation, and inhibited tumor growth in human prostate tumor (DU145) xenograft initiation model. These results suggest that A. altilis could be a good natural source and that the isolated compound will be a potential lead molecule for developing novel therapeutics against STAT3-related diseases, including cancer and inflammation.

    Comparative anatomy of twoArtocarpus species was carried out to identify and describe anatomical characters in search of distinctive characters that could possibly be used to delimit the two taxa. Transverse, tangential and radial longitudinal sections and macerated samples of the stem and root wood were prepared onto microscopic slides. Epidermal peels and cleared leaves of the two species were made. Characteristic similarity disparity in the tissues arrangement as well as cell inclusions were noted for description and delimitation. The twoArtocarpus species studied had essentially the same an-atomical features; however, there were characters that seem to be taxon specific. The study revealed that at the transverse plane of the root,A. communis(J. R. & G. Forster) have predominantly solitary vessel, whereas pore multiple was pre-dominant inA. altilis(Parkinson) Fosberg. Tyloses in vessels of the root were more frequent inA. communis than inA. altilis.In the cleared leaves, venation pattern also revealed some differences in the two species. The veins ofA. communis were more or less straight and that ofA. altilis were undulating especially in the secondary veins. Prismatic crystals were found in the cortex of the petiole inA. communis but not inA. altilis. Similarly, tannins were found in the root bark ofA. communis but not inA. altilis. Trichomes and scales were more abundant inA. communis than inA. altilis. In the transverse section of the leaves, abaxial and adaxial epidermis were uniseriate inA. communis but only the abaxial epidermis was uniseriate inA. altilis, the adaxial epidermis was made up of 2 to 3 layers of cells. The epidermal cells inA. communis were predominantly short cylindrical shaped cells but were not so inA. altilis.

    In 1953, Stanley Miller reported the production of biomolecules from simple gaseous starting materials, using apparatus constructed to simulate the primordial Earth's atmosphere-ocean system. Miller introduced 200 ml of water, 100 mmHg of H2, 200mmHg of CH4, and 200mmHg of NH3 into the apparatus, then subjected this mixture, under reflux, to an electric discharge for a week, while the water was simultaneously heated. The purpose of this manuscript is to provide the reader with a general experimental protocol that can be used to conduct a Miller-Urey type spark discharge experiment, using a simplified 3 L reaction flask. Since the experiment involves exposing inflammable gases to a high voltage discharge, it is worth highlighting important steps that reduce the risk of explosion. The general procedures described in this work can be extrapolated to design and conduct a wide variety of electric discharge experiments simulating primitive planetary environments.

  18. A critical evaluation of the Miller and Miller similar media theory for application to natural soils

    Sadeghi, Morteza; Ghahraman, Bijan; Warrick, Arthur W.; Tuller, Markus; Jones, Scott B.

    2016-05-01

    The Miller-Miller similar media theory is widely applied to characterize the spatial variability of soil hydraulic properties. For a group of soils, a distinct scaling factor is commonly assigned to each individual soil to coalesce the soil water characteristic and hydraulic conductivity functions to single curves. It is generally assumed that the Miller-Miller theory is valid as long as soils are "similar" either with regard to their microscopic pore space geometry or the closely related macroscopic soil hydraulic functions. In this paper, it is illustrated that similarity is not the sole required condition for validity of the Miller-Miller theory. In addition, the interrelation between the soil water characteristic and the hydraulic conductivity functions considered for scaling need to be comparable. The interrelation is dependent not only on the pore space geometry, but also on solid-liquid interactions. Hence similar interrelation cannot be concluded from similarity of microscopic pore space geometry. A dimensionless parameter termed the "joint scaling factor" was defined and applied to evaluate the soundness of the interrelation condition for 26 soils from the UNSODA database that were grouped into six classes of similar soils. Obtained results clearly reveal the crucial importance of the interrelation condition for the Miller-Miller scaling theory, which has been hidden behind the "similarity" requirement, and contradict the general belief that Miller-Miller scaling is valid as long as soils are "similar."

    Presents an obituary for George A. Miller (1920-2012). Miller ranks among the most important psychologists of the 20th century. In addition to writing one of the best known papers in the history of psychology ("The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information," published in Psychological Review in 1956), Miller also fomented the cognitive revolution, invented psycholinguistics and cognitive psychology, imported powerful ideas from the theories of information, communication, grammar, semantics, and artificial intelligence, and left us a sparkling oeuvre that proves that a rigorous scientist needn't write in soggy prose. Honors rained down on Miller. APA gave him the Award for Distinguished Scientific Contributions (1963), the American Psychological Foundation Gold Medal Award for Life Achievement in Psychological Science (1990), the William James Book Award (1992, for The Science of Words), and the Award for Lifetime Contributions to Psychology (2003), and named a prize after him, as did the Cognitive Neuroscience Society. Miller was also honored by the Association for Psychological Science and the American Speech and Hearing Association. In 2000, he won the John P. McGovern Award in the Behavioral Sciences from the American Association for the Advancement of Science, and in 1991, the National Medal of Science, the country's highest scientific honor.

  1. Fighting desires: Henry Miller's Queer Tropic.

    2002-01-01

    "Fighting Desires: Henry Miller's Queer Tropic" is an investigation of Tropic of Cancer that investigates the deeply repressed homoerotic desire that periodically surfaces. This reading is dependent upon an interpretation of Eve Sedgwick that proposes male sexuality as a continuum. By looking at the nature of the male-male relationships, as well as the lack of emotion and presence in the male-female relationships, I will show that the most intimate relationships are between men, and that these relationships are expressed through the telling of stories about (heterosexual) sex; this is the function of women within the novel: one has sex with a woman, not for the pleasure that the act brings, but for the pleasure that the recounting of the story to other men brings. Furthermore, I will look at Miller's use of puns within the novel and how they also contribute to a homoerotic reading. None of this is to argue that Miller was not homophobic and sexist--Miller very clearly was--the purpose of this essay is to show the complex nature of sexuality, even within a protagonist who asserts a very defined heterosexuality.

    The most promising venues for the synthesis of prebiotic molecules by Miller-Urey type processes may be found near the centres of galaxies. Explosions of supermassive stars would produce the basic chemical elements necessary to make molecules in high-density mass flows that are then acted upon by ionizing radiation, thus simulating the conditions needed for Miller-Urey type processing.

A significant antibacterial activity, as determined with the agar diffusion method, was shown by C. sativum essential oil whereas a much reduced effect was observed for F. vulgare var. vulgare oil. C. sativum and F. vulgare var. vulgare essential oils may be useful natural bactericides for the control of bacterial diseases of plants and for seed treatment, in particular, in organic agriculture. The significant antibacterial activity of essential oils to the bacterial pathogens of mushrooms appears promising.

    C. Miller Fisher MD, one of the great neurologists in the 20th century, died in April 2012. Born in Canada, he studied medicine at the University of Toronto. As a Canadian Navy medical doctor he participated in World War II and was a war prisoner from 1941 to 1944. He did a residency in neurology at the Montreal Neurological Institute between 1946 and 1948, and later on was a Fellow in Neurology and Neuropathology at the Boston City Hospital. In 1954 he entered the Massachusetts General Hospital as a neurologist and neuropathologist, where he remained until his retirement, in 2005. His academic career ended as Professor Emeritus at Harvard University. His area of special interest in neurology was cerebrovascular disease (CVD). In 1954 he created the first Vascular Neurology service in the world and trained many leading neurologists on this field. His scientific contributions are present in more than 250 publications, as journal articles and book chapters. Many of his articles, certainly not restricted to CVD, were seminal in neurology. Several concepts and terms that he coined are currently used in daily clinical practice. The chapters on CVD, in seven consecutive editions of Harrison's Internal Medicine textbook, are among his highlights. His death was deeply felt by the neurological community.

    The Miller Range ice fields have been amongst the most prolific for lunar meteorites that ANSMET has searched [1-3]. Six different stones have been recovered during the 2005, 2007, and 2009 field seasons: MIL 05035 (142 g), MIL 07006 (1.4 g), MIL 090034 (196 g), MIL 090036 (245 g), MIL 090070 (137 g), and MIL 090075 (144 g). Of these, the five stones collected during the 2007 and 2009 seasons are feldspathic breccias. Previous work on the Miller Range feldspathic lunar meteorites (FLMs) has suggested that they are not all paired with each other [4-5]. Here we examine the pairing relationships among the Miller Range FLMs using petrography in concert with traceand major-element compositions.

  13. The numerical thermodynamic analysis of Otto-Miller Cycle (OMC

    2016-01-01

    Full Text Available This paper presents a thermodynamic analysis for an irreversible Otto-Miller Cycle (OMC by taking into consideration heat transfer effects and internal irreversibilities resulting from compression and expansion processes. In the analyses, the influences of the miller cycle ratio, combustion and heat loss constants and inlet temperature have been investigated relations with efficiency in dimensionless form. The dimensionless power output and power density and thermal efficiency relations have been computationally obtained versus the engine design parameters with respect to combustion and heat transfer constants. The results demonstrate that the heat transfer and combustion constants have considerable effects on the cycle thermodynamic performance. This situation theoretically verified for OMC.

    Following the discovery of an archived set of samples from Stanley Miller's early experiments, analyses were undertaken to better understand the diversity of compounds produced from electric discharges acting on reducing gas mixtures. The paper chromatography methods that Miller used in the 1950s were only capable of detecting a few amino acids and were unable to provide substantial quantitative data relative to today's techniques. Current analytical techniques are much more sensitive and selective, and are capable of precisely quantifying a much larger range of amino acids and their enantiomeric abundances. In one study, preserved dried samples produced by Miller using a lesser-known volcanic apparatus which differed from Miller's classic apparatus in that it utilized an aspirator that injected steam into the electric discharge chamber, simulating a volcanic eruption. The volcanic apparatus produced a wider variety of amino acids than the classic configuration. Prebiotic compounds synthesized in these environments may have locally accumulated where they could have undergone further processing. An additional preserved set of samples from an experiment conducted in 1958 were also found in Miller's archived collection. These samples which had been generated using a mixture of CH4, NH3, H2S and CO2 were collected, catalogued, and stored by Miller, but for unknown reasons were never studied. In our analyses a total of 23 amino acids and 4 amines, including 7 organosulfur compounds, were detected in these samples. The major amino acids with chiral centers are racemic within the accuracy of the measurements, indicating that they are not contaminants introduced during sample storage. This experiment marks the first synthesis of sulfur amino acids from spark discharge experiments designed to imitate primordial environments. The relative yield of some amino acids, in particular the isomers of amino butyric acid, are the highest ever found in a spark discharge experiment

    The purpose of this study was to analyze previously reported airway risk factors in the performance of Miller laryngoscopy and orotracheal intubation. Prospective, observational study. Operating rooms. A total of 978 American Society of Anesthesiologists I-III adults requiring general orotracheal anesthesia for elective surgery. None. Nine previously reported airway risk factors used in predicting difficult laryngoscopy, modified McCormack-Lehane views observed during initial unaided Miller blade laryngoscopy, and number of attempts or need for alternate airway tools to facilitate orotracheal intubation. Orotracheal intubation occurred in 941 of 978 (96.2%) patients with the Miller blade, although 8 patients required 3 attempts, with the remaining 37 patients requiring alternate airway tools. There were no failed orotracheal intubations. Multivariable analysis revealed that modified Mallampati class, thyromental distance, and ability to prognath were associated with progressively inferior modified Cormack-Lehane views, whereas modified Mallampati class, height, and head and neck extension were associated with progressive difficulty with orotracheal intubation. The Miller blade is highly successful in the performance of direct laryngoscopy for orotracheal intubation. These findings suggest that different sets of airway risk factors affect the process of laryngoscopy and orotracheal intubation. Copyright © 2016 Elsevier Inc. All rights reserved.

    McDonald, A D; Case, B W; Churg, A; Dufresne, A; Gibbs, G W; Sébastien, P; McDonald, J C

    1997-12-01

    In a cohort of some 11,000 men born 1891-1920 and employed in the Quebec chrysotile production industry, including a small asbestos products factory, of 9780 men who survived into 1936, 8009 are known to have died before 1993, 38 probably from mesothelioma--33 in miners and millers and five in factory workers. Among the 5041 miners and millers at Thetford Mines, there had been 4125 deaths from all causes, including 25 (0.61%) from mesothelioma, a rate of 33.7 per 100,000 subject-years; the corresponding figures for the 4031 men at Asbestos were eight out of 3331 (0.24%, or 13.2 per 100,000 subject-years). At the factory in Asbestos, where all 708 employees were potentially exposed to crocidolite and/or amosite, there were 553 deaths, of which five (0.90%) were due to mesothelioma; the rate of 46.2 per 100,000 subject-years was 3.5 times higher than among the local miners and millers. Six of the 33 cases in miners and millers were in men employed from 2 to 5 years and who might have been exposed to asbestos elsewhere; otherwise, the 22 cases at Thetford were in men employed 20 years or more and the five at Asbestos for at least 30 years. The cases at Thetford were more common in miners than in millers, whereas those at. Asbestos were all in millers. Within Thetford Mines, case-referent analyses showed a substantially increased risk associated with years of employment in a circumscribed group of five mines (Area A), but not in a peripherally distributed group of ten mines (Area B); nor was the risk related to years employed at Asbestos, either at the mine and mill or at the factory. There was no indication that risks were affected by the level of dust exposure. A similar pattern in the prevalence of pleural calcification had been observed at Thetford Mines in the 1970s. These geographical differences, both within the Thetford region and between it and Asbestos, suggest that the explanation is mineralogical. Lung tissue analyses showed that the concentration of

    51-year-old female who presented with progressive paresthesia, numbness of the lower extremities, double vision, and trouble walking. Physical exam was remarkable for areflexia, and ptosis. Her initial EKG showed nonspecific ST segment changes and her Troponin T was elevated to 0.41ng/mL which peaked at 0.66ng/mL. Echocardiogram showed a depressed left ventricular ejection fraction to 35% with severely hypokinetic anterior wall and left ventricular apex was severely hypokinetic. EMG nerve conduction study showed severely decreased conduction velocity and prolonged distal latency in all nerves consistent with demyelinating disease. She was treated with 5days of intravenous immunoglobulin therapy to which she showed significant improvement in strength in her lower extremities. Echocardiogram repeated 4days later showing an improved left ventricular ejection fraction of 55% and no left ventricular wall motion abnormalities. Takotsubo cardiomyopathy is a rare complication of Miller-Fisher syndrome and literature review did not reveal any cases. Miller-Fisher syndrome is an autoimmune process that affects the peripheral nervous system causing autonomic dysfunction which may involve the heart. Due to significant autonomic dysfunction in Miller-Fisher syndrome, it could lead to arrhythmias, blood pressure changes, acute coronary syndrome and myocarditis, Takotsubo cardiomyopathy can be difficult to distinguish. The treatment of Takotsubo cardiomyopathy is supportive with beta-blockers and angiotensin-converting enzyme inhibitors are recommended until left ventricle ejection fraction improvement. Takotsubo cardiomyopathy is a rare complication during the acute phase of Miller-Fisher syndrome and must be distinguished from autonomic dysfunction as both diagnoses have different approaches to treatment.

  9. On the Attraction of Matter by the Ponderomotive Miller Force

    CERN Document Server

    Lundin, Rickard

    2010-01-01

    Wave induced attraction of matter is a unique aspect of ponderomotive forcing by electromagnetic (e/m) waves in plasmas. The Miller force, sometimes denoted the gradient force, is of particular interest, because the direction as well as magnitude of the Miller force on a plasma depends on the wave frequency. While plasma is usually considered in its gaseous form, solid bodies can also be treated as plasma, denoted solid-state plasma. The first experimental proof of wave effects in magnetized solid-state plasmas (Lundqvist, 1949, Herlofson, 1950) came after the suggestion by Alfv\\'en (1942) on the possible existence of magneto-hydrodynamic (MHD) waves. However, most of our knowledge basis on MHD/Alfv\\'en waves have since then emerged from space- and laboratory (gaseous) plasmas. It is therefore timely to investigate further the applicability of e/m wave ponderomotive forcing on solid-state plasma. In this report we discuss the applicability of the ponderomotive Miller force on solid-state plasmas. At this stag...

  10. Hybrid Automotive Engine Using Ethanol-Burning Miller Cycle

    Science.gov (United States)

    Weinstein, Leonard

    2004-01-01

    A proposed hybrid (internal-combustion/ electric) automotive engine system would include as its internal-combustion subsystem, a modified Miller-cycle engine with regenerative air preheating and with autoignition like that of a Diesel engine. The fuel would be ethanol and would be burned lean to ensure complete combustion. Although the proposed engine would have a relatively low power-to-weight ratio compared to most present engines, this would not be the problem encountered if this engine were used in a non-hybrid system since hybrid systems require significantly lower power and thus smaller engines than purely internal-combustion-engine-driven vehicles. The disadvantage would be offset by the advantages of high fuel efficiency, low emission of nitrogen oxides and particulate pollutants, and the fact that ethanol is a renewable fuel. The original Miller-cycle engine, named after its inventor, was patented in the 1940s and is the basis of engines used in some modern automobiles, but is not widely known. In somewhat oversimplified terms, the main difference between a Miller-cycle engine and a common (Otto-cycle) automobile engine is that the Miller-cycle engine has a longer expansion stroke while retaining the shorter compression stroke. This is accomplished by leaving the intake valve open for part of the compression stroke, whereas in the Otto cycle engine, the intake valve is kept closed during the entire compression stroke. This greater expansion ratio makes it possible to extract more energy from the combustion process without expending more energy for compression. The net result is greater efficiency. In the proposed engine, the regenerative preheating would be effected by running the intake air through a heat exchanger connected to the engine block. The regenerative preheating would offer two advantages: It would ensure reliable autoignition during operation at low ambient temperature and would help to cool the engine, thereby reducing the remainder of the

    Transmission through a potential barrier, and the related issue of particle production from a parametric resonance, are topics of considerable general interest in quantum physics. The authors have developed a rather general bound on quantum transmission probabilities, and recently applied it to bounding the greybody factors of a Schwarzschild black hole. In the current article we take a different tack -- we use the Miller-Good transformation (which maps an initial Schrodinger equation to a final Schrodinger equation for a different potential) to significantly generalize the previous bound.

  18. Amending Miller's Pyramid to Include Professional Identity Formation.

    Science.gov (United States)

    Cruess, Richard L; Cruess, Sylvia R; Steinert, Yvonne

    2016-02-01

    In 1990, George Miller published an article entitled "The Assessment of Clinical Skills/Competence/Performance" that had an immediate and lasting impact on medical education. In his classic article, he stated that no single method of assessment could encompass the intricacies and complexities of medical practice. To provide a structured approach to the assessment of medical competence, he proposed a pyramidal structure with four levels, each of which required specific methods of assessment. As is well known, the layers are "Knows," "Knows How," "Shows How," and "Does." Miller's pyramid has guided assessment since its introduction; it has also been used to assist in the assessment of professionalism.The recent emphasis on professional identity formation has raised questions about the appropriateness of "Does" as the highest level of aspiration. It is believed that a more reliable indicator of professional behavior is the incorporation of the values and attitudes of the professional into the identity of the aspiring physician. It is therefore proposed that a fifth level be added at the apex of the pyramid. This level, reflecting the presence of a professional identity, should be "Is," and methods of assessing progress toward a professional identity and the nature of the identity in formation should be guided by currently available methods.

    The Miller-Urey experiments pioneered modern research on the molecular origins of life, but their actual relevance in this field was later questioned because the gas mixture used in their research is considered too reducing with respect to the most accepted hypotheses for the conditions on primordial Earth. In particular, the production of only amino acids has been taken as evidence of the limited relevance of the results. Here, we report an experimental work, combined with state-of-the-art computational methods, in which both electric discharge and laser-driven plasma impact simulations were carried out in a reducing atmosphere containing NH3 + CO. We show that RNA nucleobases are synthesized in these experiments, strongly supporting the possibility of the emergence of biologically relevant molecules in a reducing atmosphere. The reconstructed synthetic pathways indicate that small radicals and formamide play a crucial role, in agreement with a number of recent experimental and theoretical results.

    Eruca sativa Miller is a worldwide common alimentary plant (rocket leaves). The aim of this study was to correlate the potential in vitro scavenging activity of the E. sativa hydroalcoholic extract (HAE) with its in vivo hypoglycaemic effect. In DDPH free radical (DFR) and ferric-reducing antioxidant power assays, HAE in a concentration dependent manner (25-100 μg/mL) displayed a strong scavenging activity with maximum effect of 88% and 75% at 100 μg/mL, respectively. Daily administration of HAE (50 mg/kg; p.o.) in the in vivo model of alloxan-induced diabetic rabbits for 28 days showed significant reduction in glycaemia, also supported by recovery of body weight. In conclusion, our results give preliminary information on the potential use of this plant as a nutraceutical, useful to control and/or prevent a hyperglycaemic status.

  7. Karp-Miller Trees for a Branching Extension of VASS

    Full Text Available We study BVASS (Branching VASS which extend VASS (Vector Addition Systems with States by allowing addition transitions that merge two configurations. Runs in BVASS are tree-like structures instead of linear ones as for VASS. We show that the construction of Karp-Miller trees for VASS can be extended to BVASS. This entails that the coverability set for BVASS is computable. This allows us to obtain decidability results for certain classes of equational tree automata with an associative-commutative symbol. Recent independent work by de Groote et al. implies that decidability of reachability in BVASS is equivalent to decidability of provability in MELL (multiplicative exponential linear logic, which is still an open problem. Hence our results are also a step towards answering this question in the affirmative.

    Full Text Available Chronic lymphocytic leukemia (CLL is a frequent hematological malignancy, with meningeal or peripheral nerve infiltrations being the most commonly encountered neurological complications. In this report, we describe a CLL patient with Miller-Fisher syndrome (MFS who responded to immune modulation with plasmapheresis. A 47-year-old man diagnosed as B-cell CLL admitted with neutropenic fever. He complained of diplopia and numbness of both arms. Neurological examination revealed a bilateral external ophthalmoplegia, dysphagia, dysarthria, mild shoulder girdle muscle weakness and gait ataxia, accompanied by absent tendon reflexes. Nerve conduction studies were indicative of a predominantly axonal sensori-motor peripheral neuropathy. This association of CLL with MFS had not been previously reported in the literature.

  9. George A. Miller, language, and the computer metaphor of mind.

    Science.gov (United States)

    Crowther-Heyck, H

    1999-02-01

    This article asks why the analogy between humans and computers was understood by cognitive psychologists to mean that "minds exist and that it is our job as psychologists to study them". Earlier psychologists, such as Clark Hull, used analogies between humans and complex machines such as telephone switchboards to defend a rigorous behaviorism. How, then, did the computer metaphor of mind come to be seen as the root concept underlying a paradigm shift from behaviorism to cognitivism? To answer this question, this article examines the life and work of George A. Miller, one of the most prominent of a generation of psychologists who began their careers as "good behaviorists" but later came to embrace cognitivism.

    The pollen morphology of six taxa of the genus Acinos Miller has been examined under scanning electron microscopy(SEM) and a description of each taxon has been given. Acinos pollen is stephanocolpate (hexacolpate). Two main exine sculpturing types, foveolate-reticulate (only in subspecies of A. troodi) and reticulate have been defined. The dimension for the polar length ranges between 25.8-47.4 μm, equatorial width 24.5-34.4 μm, colpus length 20.0-40.5 μm and colpus width 1.2-2.5 μm. The shape is mostly subprolate to prolate, seldomly prolate-spheroidal. The results reveal rather uniform morphological features, however fine details are characteristic to differentiate the pollen taxa. Acinos pollen also share some common morphological features with the other Lamiaceae pollen.

    We report on a patient prenatally diagnosed with omphalocele, mild cerebral ventriculomegaly, nuchal fold thickening, and cystic changes in the umbilical cord who was found postnatally to have lissencephaly type I. Prenatal chromosome analysis showed a normal male karyotype; however, postnatal high resolution banding and FISH analysis, using a probe for locus D17S379 in chromosome region 17p13.3, demonstrated a deletion at 17p13.3 consistent with Miller-Dieker syndrome (MDS). A review documented four more cases with MDS/isolated lissencephaly/17p-, with omphalocele. Because MDS is a contiguous gene disorder, we speculate that a gene or genes in this region have a major role in the closure of the lateral folds or the return of the midgut from the body stalk to the abdomen at 5-11 weeks of gestation. Prenatal diagnosis of omphalocele with mild ventriculomegaly should prompt FISH analysis for a deletion in 17p13.3. 44 refs., 7 figs., 1 tab.

    2013-06-01

    Long-term rupture data for 79 types of heat-resistant steels including carbon steel, low-alloy steel, high-alloy steel, austenitic stainless steel, and superalloy were analyzed, and a constant for the Larson-Miller (LM) parameter was obtained in the current study for each material. The calculated LM constant, C, is approximately 20 for heat-resistant steels and alloys except for high-alloy martensitic steels with high creep resistance, for which C ≈ 30 . The apparent activation energy was also calculated, and the LM constant was found to be proportional to the apparent activation energy with a high correlation coefficient, which suggests that the LM constant is a material constant possessing intrinsic physical meaning. The contribution of the entropy change to the LM constant is not small, especially for several martensitic steels with large values of C. Deformation of such martensitic steels should accompany a large entropy change of 10 times the gas constant at least, besides the entropy change due to self-diffusion.

  14. Adaptation: a contemporary view, revisiting Crichton-Miller's 1925 paper.

    Science.gov (United States)

    Music, Graham

    2016-03-01

    In this paper I discuss a contemporary 'take' on the concept of adaptation in light of Crichton-Miller's original 1926 paper. I look briefly at some of the ways that contemporary thinking is both similar to and different from ideas of 90 years ago. In particular I think about how recent neurobiological findings, epigenetic research and attachment theory have cast new light on our understanding of the ways humans adapt to social and emotional environments. It looks at how psychiatric presentations which are seen as maladaptive might well have an adaptive origin in early life. In this account I emphasise how a more modern version of evolutionary theory can be developed, particularly one influenced by life history theory, and suggest that such ideas have powerful explanatory power as well as being based solidly in good research.

    The dry leaves of Aloe barbadensis Miller irrigated with seawater were dissolved in nitric acid and then oxygenated by perchloric acid. Nine kinds of trace elements in the samples were determined by atomic absorption spectrophotometry, including calcium, potassium, magnesium, sodium, manganese, zinc, iron, copper and lead, with added lanthanum chloride as releaser to eliminate the interference of co-existent ions. The recoveries were 96.58%-104.31%, and the relative standard deviations of sample determination (10 times) were less than 2%. This method is simple, sensitive and rapid with satisfactory results and good reproducibility. The results indicated that there were rich Ca, Mg, K and Na, and moderate Mn, Zn and Fe elements in the Aloe barbadensis Miller irrigated with seawater. However, the concentrations of Cu and Pb were low. Therefore, Aloe barbadensis Miller irrigated with seawater has officinal and economic values. These results provide data for further research on Aloe barbadensis Miller irrigated with seawater.

    One of the major alternatives of the Otto cycle has been examined to determine its potential for increased efficiency and net work power in the spark ignited internal combustion engine is to shorten the compression process relative to the expansion process by early close or late of intake valve. The modified Otto cycle is called Miller cycle. This paper deals with the analysis of a supercharged Otto engine adopted for Miller cycle operation. The Miller cycle shows no efficiency advantage and suffers a penalty in power output in the normally aspirated version. In the supercharged Otto engine adopted for Miller cycle version, it has no efficiency advantage but does provide increased net work output with reduced propensity to engine knock problem. Sensitivity analysis of cycle efficiency versus early close of intake valve and that of cycle net work versus early close of intake valve are performed. Optimization on the cycle efficiency is obtained. (author)

    Miller Fisher syndrome (MFS) has been considered as a variant of Guillain-Barre syndrome (GBS), a type of acute immune neuropathies involving peripheral nerve system. Unlike GBS, presence of cerebellar type ataxia and supranuclear ophthalmioplesia in MFS suggests additional involvement of the central nervous system. To determine involvement of the central nervous system in MFS, we investigated the cerebral metabolic abnormalities in patients with MFS using FDG PET. Nine patients who were diagnosed as MFS based on acute ophthalmoplegia, ataxia, and areflexia without other identifiable causes participated in this study. In six patients, serum antibodies possibly related with symptom of MFS (anti- GQ1b or anti-GM1) were detected at the time of the study. With the interval of 25 26 days (range: 3-83 days) from the symptom on set, brain FDG PET were underwent in patients and compared with those from healthy controls. In group analysis comparing with healthy controls, FDG PET of patients revealed increased metabolism in the bilateral cerebellar hemispheres and vermis, and the thalamus. In contrast, the occipital cortex showed decreased metabolism. Individual analyses disclosed hypermetabolism in the cerebellar vermis or hemispheres in 5, and in the pontine tegmentum in 2 of the 9 patients. We also found that the cerebellar vermian hypermetabolism was inversely correlated with the interval between from the symptom on set to PET study. Moreover, follow-up PET of a patient demonstrated that cerebellar hypermetabolism decreased markedly with an improvement of the ophthalmoplegia and ataxia. These findings indicate an involvement of the central nervous system in MFS and suggest an antibody-associated acute inflammatory process as a mechanism of this disorder.

    Continuous professional development relies on the link between performance and an educational process aimed at improving knowledge and skill. One of the most broadly used frameworks for assessing skills is Miller's Pyramid. This Pyramid has a series of levels of achievement beginning with knowledge (at the base) and ending with routine application in the clinical setting. The purpose of this study was to determine the degree of convergence of two measurement methods, one based on Miller's framework, the second using the Accreditation Council for Graduate Medical Education/American Board of Medical Specialties (ACGME/ABMS) Core Competency framework. The data were gathered from the faculty of a large, Midwestern regional health care provider and hospital system. Data from 264 respondents were studied. The 360° data were from raters of physicians holding supervisory roles in the organization. The scale items were taken from an instrument that has been validated for both structure and known group prediction. The Miller scale was purposely built for this application. The questions were designed to describe each level of the model. The Miller scale was reduced to a single dimension. This result was then regressed on the items from the 360° item ratings. Results of a multivariate analysis of variance isolated a significant relationship between the Miller's Pyramid score and the competency items (P core competencies. Equally important is the finding that while they are related they are not identical. These findings have implications for continuous professional development programing design.

    The objective of this study was to determine if there was a difference in the amount, type, and location of backside wear in the Miller-Galante I and Insall-Burstein II PE tibial inserts. A secondary objective was to determine if backside wear damage in these two designs was a function of clinical factors (patient height, weight, gender, age, and length of time of implantation), shelf life of the PE tibial insert, and tibial component thickness. Backside wear damage was assessed on 24 Miller-Galante I and 11 Insall-Burstein II tibial inserts (implantation time, 0.5-12.4 years). For both groups combined, implantation time was positively correlated to wear damage and to PE peg height into screw holes. The Miller-Galante I group had significantly larger PE pegs than the Insall-Burstein II group. The Miller-Galante I group had significantly more burnishing and larger PE pegs posteriorly than anteriorly. There was no correlation between insert shelf life before initial surgery and backside wear. The thinner the component, the larger the total damage scores in the Miller-Galante I group. This study supports the hypothesis that backside wear of PE tibial inserts may be influenced by design and component thickness and by clinical factors.

    Sixty years after the seminal Miller-Urey experiment that abiotically produced a mixture of racemized amino acids, we provide a definite proof that this primordial soup, when properly cooked, was edible for primitive organisms. Direct admixture of even small amounts of Miller-Urey mixture strongly inhibits E. coli bacteria growth due to the toxicity of abundant components, such as cyanides. However, these toxic compounds are both volatile and extremely reactive, while bacteria are highly capable of adaptation. Consequently, after bacterial adaptation to a mixture of the two most abundant abiotic amino acids, glycine and racemized alanine, dried and reconstituted MU soup was found to support bacterial growth and even accelerate it compared to a simple mixture of the two amino acids. Therefore, primordial Miller-Urey soup was perfectly suitable as a growth media for early life forms.

  10. New insights into prebiotic chemistry from Stanley Miller's spark discharge experiments.

    2013-03-07

    1953 was a banner year for biological chemistry: The double helix structure of DNA was published by Watson and Crick, Sanger's group announced the first amino acid sequence of a protein (insulin) and the synthesis of key biomolecules using simulated primordial Earth conditions has demonstrated by Miller. Miller's studies in particular transformed the study of the origin of life into a respectable field of inquiry and established the basis of prebiotic chemistry, a field of research that investigates how the components of life as we know it can be formed in a variety of cosmogeochemical environments. In this review, I cover the continued advances in prebiotic syntheses that Miller's pioneering work has inspired. The main focus is on recent state-of-the-art analyses carried out on archived samples of Miller's original experiments, some of which had never before been analyzed, discovered in his laboratory material just before his death in May 2007. One experiment utilized a reducing gas mixture and an apparatus configuration (referred to here as the "volcanic" apparatus) that could represent a water-rich volcanic eruption accompanied by lightning. Another included H(2)S as a component of the reducing gas mixture. Compared to the limited number of amino acids Miller identified, these new analyses have found that over 40 different amino acids and amines were synthesized, demonstrating the potential robust formation of important biologic compounds under possible cosmogeochemical conditions. These experiments are suggested to simulate long-lived volcanic island arc systems, an environment that could have provided a stable environment for some of the processes thought to be involved in chemical evolution and the origin of life. Some of the alternatives to the Miller-based prebiotic synthesis and the "primordial soup" paradigm are evaluated in the context of their relevance under plausible planetary conditions.

    Miller Fisher syndrome (MFS) is a localized variant of Guillain-Barré syndrome (GBS), characterized by ophthalmoplegia, areflexia, and ataxia. Recent neurophysiological studies have suggested that abnormal terminal axon dysfunction occurs in some cases of Miller Fisher syndrome and Guillain-Barrd syndrome. We present a rare case report of recurrent MFS with abnormal terminal axon dysfunction. To the best of our knowledge, this is the first case report of recurrent MFS with terminal axon dysfunction that persisted up to nine months after the initial presentation of the second attack with positive antiganglioside antibodies and full clinical recovery.

    2016-01-01

    We identify a fundamental space-time invariance principle by combining the thesis of the conventionality of simultaneity with the Hugyens-Fresnel-Miller model of wave propagation. By following the standard gauge prescription, we show that the classical electromagnetic potentials influence the one-way speed of light.

    1979-01-01

    Nitrogen isotope fractionations have been measured in Fischer-Tropsch and Miller-Urey reactions in order to determine whether these processes can account for the large N-15/N-14 ratios found in organic matter in carbonaceous chondrites. Polymeric material formed in the Fischer-Tropsch reaction was enriched in N-15 by only 3 per mil relative to the starting material (NH3). The N-15 enrichment in polymers from the Miller-Urey reaction was 10-12 per mil. Both of these fractionations are small compared to the 80-90 per mil differences observed between enstatite chondrites and carbonaceous chondrites. These large differences are apparently due to temporal or spatial variations in the isotopic composition of nitrogen in the solar nebula, rather than to fractionation during the production of organic compounds.

    Cydonia oblonga Miller (quince) is regarded as a potent libido invigorator in Tib-e-Nabvi and Unani System of Medicine. This study was carried out to evaluate the aphrodisiac activity of the hydroalcoholic extract of the fruits of Cydonia oblonga Miller (quince) in Wistar rats. The extract was administered orally by gavage in the dose of 500 mg/kg and 800 mg/kg body weight per day as a single dose for 28 days. The observed parameters were mounting frequency, assessment of mating performance, and orientation activities towards females, towards the environment, and towards self. The results showed that after administration of the extract mounting frequency and the mating performance of the rats increased highly significantly (P < 0.01). The extract also influenced the behaviour of treated animals in comparison to nontreated rats in a remarkable manner, making them more attracted to females. These effects were observed in sexually active male Wistar rats.

    The mechanism of motor weakness in patients with Miller-Fisher syndrome (MFS) remains to be fully elucidated. We performed stimulated single fibre electromyography (sSFEMG) in a clinically weak frontalis muscle in a patient with MFS. Stimulate single fiber EMG revealed increased jitter in over 50% of the apparent single fibre action potentials from the frontalis muscle in addition to increased mean jitter. The findings in the present study suggest dysfunction of neuromuscular transmission in patients with MFS.

    In a famous experiment Stanley Miller showed that a large number of organic substances can emerge from sparking a mixture of methane, ammonia and hydrogen in the presence of water (Miller, Science 117:528-529, 1953). Among these substances Miller identified different amino acids, and he concluded that prebiotic events may well have produced many of Life's molecular building blocks. There have been many variants of the original experiment since, including different gas mixtures (Miller, J Am Chem Soc 77:2351-2361, 1955; Oró Nature 197:862-867, 1963; Schlesinger and Miller, J Mol Evol 19:376-382, 1983; Miyakawa et al., Proc Natl Acad Sci 99:14,628-14,631, 2002). Recently some of Miller's remaining original samples were analyzed with modern equipment (Johnson et al. Science 322:404-404, 2008; Parker et al. Proc Natl Acad Sci 108:5526-5531, 2011) and a total of 23 racemic amino acids were identified. To give an overview of the chemical variety of a possible prebiotic broth, here we analyze a "Miller type" experiment using state of the art mass spectrometry and NMR spectroscopy. We identify substances of a wide range of saturation, which can be hydrophilic, hydrophobic or amphiphilic in nature. Often the molecules contain heteroatoms, with amines and amides being prominent classes of molecule. In some samples we detect ethylene glycol based polymers. Their formation in water requires the presence of a catalyst. Contrary to expectations, we cannot identify any preferred reaction product. The capacity to spontaneously produce this extremely high degree of molecular variety in a very simple experiment is a remarkable feature of organic chemistry and possibly prerequisite for Life to emerge. It remains a future task to uncover how dedicated, organized chemical reaction pathways may have arisen from this degree of complexity.

    Background: The aims of the present study were to (i) Find the percentage of recession cases that could be classified by application of Miller's and/or Kumar and Masamatti's classification of gingival recession, and (ii) compare the percentage of clinical applicability of Miller's criteria and Kumar and Masamatti's criteria to the total recessions present. Materials and Methods: A total of 104 patients (1089 recession cases) were included in the study wherein they were classified using both Miller's and Kumar and Masamatti's classification systems of gingival recession. Percentage comparison of the application of both classification systems was done. Results: Data analysis showed that though all the cases of the recession were classified by Kumar and Masamatti's classification, only 34.61% cases were classified by Miller's classification. 19.10% cases were completely (having only labial/buccal recession) classified. In 15.51% (out of 34.61%) cases, only buccal recession was classified according to Miller's criteria and included in this category, although these cases had both buccal and lingual/palatal recessions. Furthermore, 29.75% cases of recession with interdental loss and marginal tissue loss coronal to mucogingival junction (MGJ) remained uncategorized by Miller's classification; categorization of palatal/lingual recession was possible with Kumar and Masamatti's classification. Conclusion: The elaborative evaluation of both buccal and palatal/lingual recession by the Kumar and Masamatti's classification system can be used to overcome the limitations of Miller's classification system, especially the cases with interdental loss and having marginal tissue loss coronal to MGJ.

    If one is going to argue that objective morality depends on an Archimedean point outside the natural world, then it would seem to imply that this source is necessarily supernatural. Thus, Christian Miller begins by defining precisely who he thinks this supernatural moral law giver is: the omniscient, omnipotent, and omnibenevolent creator of the universe who is still actively involved with human affairs-Elohim, Jehovah, Yahweh, or Allah-aka God. Already I'm skeptical. © 2016 New York Academy of Sciences.

    Full Text Available A former model and fashion photographer turned war photographer, Lee Miller visited Romania twice, in 1938 and 1946 respectively. After her second visit she published her impressions and pictures, under the title of Roumania, in Vogue magazine. Besides the published material there are her manuscripts from The Lee Miller Achives at Farley Farm House, East Sussex, England, on which this paper is based. She crossed the border coming from Hungary in early February 1946. Heading for Sibiu her car, a Chevrolet Sedan, slipping on the ice-covered road, stopped on a snowbank far off in the ditch. While looking for help in the nearby village she and her companions left the car unguarded to discover it plundered of everything, wheels included.On a Sunday afternoon she had the privilege of being received by King Mihai I and Queen Mother Elena with whom she talked exstensively. She also took magnificent pictures with the Royal Family in the imposing Peleş Castle. At Sinaia, „the summer capital of Roumania” she had also the opportunity to portray Dinu Brătianu and Iuliu Maniu, the two elderly statesmen. Maniu was surrounded by friends and party members, among whom was young Corneliu Coposu, his private secretary.Moving to Bucharest, she met old friends such as Harri Brauner and his wife, Lena Constante, with whom she wandered through the country eight years ago. Lena and Elena Pătrășcanu, wife of Lucrețiu Pătrășcanu, Minister of Justice, have started a successful marionette theatre where Lee took nice pictures. Other were taken on the streets, with peasants, street vendors and their customers. Harri took her to a bistro where they met Maria Lătărețu, the celebrating folk singer whom Brauner recorded many times. They enjoyed her songs. Suffering from fibrositis, Lee Miller undertook a peculiar treatment in a gypsy village where the inhabitants were dancing bears trainers.

    2012-03-01

    Full Text Available The heroic defence of the Greeks at the battle of Thermopylae in 480 BC, in particularly the 300 Spartans who stood to the last man against the much larger Persian force, prompted comic book writer and illustrator Frank Miller to retell this story from a purely Spartan perspective. This version was retold once again when director Zack Snyder created a filmed version of the graphic novel named 300. Despite the film’s achievements at the box office, it was attacked for being, amongst others, historically incorrect and ideologically biased. In the graphic novel Frank Miller tells the tale of the battle at Thermopylae through the eyes of a Spartan warrior who bore the responsibility of spreading their tale so that the Spartans’ sacrifice might compel other Greek city-states to stand together against the Persians. Therefore the graphic novel and especially the film are drenched with Spartan superiority and Persian inferiority. Despite the inaccuracies and ideological bias, there are a few moments in the graphic novel and film that are notably historically correct.

    Full Text Available The North American writer Henry Miller was marginalized by literary critics since the first publications of his works in the 40s. Accused of being a pornographic text, the book Tropic of Cancer (1934 was forbidden in many countries. This article aims to analyze the obscene in Henry Miller’s work to prove that, beyond the erotic intention, Miller’s books are an expression of freedom and rejection of moral standards. In order to achieve our goal, we will use as theoretical basis the articles Criticismo e sexualidade: uma leitura de Tropico of Capricorn de Henry Miller, by Flávia Andréa Rodrigues Benfatt, and Literatura marginal americana: do épico confessional ao niilismo erótico, by Lainister de Oliveira. The texts mentioned above grant us the argumentation necessary to the analysis of pornographic discourse in Henry Miller’s literary works as the author’s aesthetics choice of taking himself as a transgressor in a decadent society.

    This paper describes an integrated circuit design for a modified charge-sensitive amplifier (CSA) that compensates for the effect of capacitance presented by nuclear radiation detectors and other sensors. For applications that require large area semiconductor detectors or for those semiconductor sensors derived from high permittivity materials such as PbSe, the detector capacitance can degrade the system gain and bandwidth of a front-end preamplifier, resulting in extended rise times and attenuated output voltage signals during pulse formation. In order to suppress the effect of sensor capacitance, we applied a bootstrap technique into a traditional CSA. The technique exploits the Miller effect by reducing the effective voltage difference between the two sides of a radiation detector which minimizes the capacitance presented to the differential common-source amplifier. This new configuration is successfully designed to produce effective gain even at high detector capacitance. The entire circuit, including a core CSA with feedback components and a bootstrap amplifier, are implemented in a 0.18 μm CMOS process with a 3.3 V supply voltage. - Highlights: • A modified CSA was implemented for detector capacitance compensation. • Increasing detector capacitance degrades gain and rise time. • A bootstrap amplifier exploiting the Miller effect is described. • It allows using large area radiation sensors for high radiation-interaction rates. • Intensive noise analyses show that SNR is much better with the technique.

    Arthur Miller, one of the most admirable of Americans to come out of the ″American century″, died in 2005, aged 89. In the UK, at least, his work has undergone a revival and the themes of his great plays remain resonant, even though, in many respects, they are historically specific. The relationship between literature and history - whether conceived as a symbolist or allegorical relationship - together with an instance of the past invading the present, are brought out in a compelling episode in Miller's autobiography, Timebends, and offer a way of talking about those inter-connections in The Crucible.

    Henry James’s first novella Daisy Miller brought him popularity and literary reputation after its publication. Through the application of reader theory and a close reading of the text, this article analyzes Daisy’s strong personality and her misfortunes during her trip to Europe, and reveals how the novella highlights the conflict between American frankness and innocence and Eu-ropean sophistication. Besides, this article also elaborates on James’unique artistic skills-central consciousness and psychological analysis through his choice of narrative point of view, which contribute to the theme and the artistic charm of Daisy Miller.

    2015-01-01

    Modified coronally advanced tunnel (MCAT) technique with connective tissue graft (CTG) was used in treating multiple adjacent Miller Class III gingival recessions in nine patients. Clinical evaluations were recorded at baseline and 12 months after surgery. The results showed that 50% of complete root coverage and 78% of mean root coverage were attained 1 year after surgery and interdental space fill was 73% at 12 months. The study demonstrated that CTG using the MCAT technique may be an efficient way to treat multiple adjacent Miller Class III gingival recessions, especially when aiming for interdental space fill. Success, however, seems to be related to the amount of tissue present initially.

  15. Miller-Fisher Syndrome: Are Anti-GAD Antibodies Implicated in Its Pathophysiology?

    Full Text Available Miller-Fisher syndrome (MFS is considered as a variant of the Guillain-Barre syndrome (GBS and its characteristic clinical features are ophthalmoplegia, ataxia, and areflexia. Typically, it is associated with anti-GQ1b antibodies; however, a significant percentage (>10% of these patients are seronegative. Here, we report a 67-year-old female patient who presented with the typical clinical features of MFS. Workup revealed antibodies against glutamic acid decarboxylase (GAD in relatively high titers while GQ1b antibodies were negative. Neurological improvement was observed after intravenous gamma globulin and follow-up examinations showed a continuous clinical amelioration with simultaneous decline of anti-GAD levels which finally returned to normal values. This case indicates that anti-GAD antibodies may be associated with a broader clinical spectrum and future studies in GQ1b-seronegative patients could determine ultimately their clinical and pathogenetic significance in this syndrome.

    This paper, by one of the legends of hematology, William Dameshek, and his colleague Edward Miller, is from the inaugural issue of Blood. By studying bone marrow specimens from controls, patients with acute or chronic immune thrombocytopenia, or patients with other thrombocytopenic disorders, the authors concluded that, in idiopathic thrombocytopenic purpura (ITP), production of platelets from megakaryocytes is defective, even while marrow megakaryocytes are greatly increased in number. This defect resolved after splenectomy. The authors appropriately credit E. Frank with having proposed defective platelet production from megakaryocytes in ITP in 1915. The idea that platelet production was defective in ITP was superseded or ignored for decades, but it has now been validated by the therapeutic effectiveness of the thrombopoietin mimetics in ITP.

    2005-01-01

    The Miller Assessment for Preschoolers (MAP) is a standardized test purported to identify preschool-aged children at risk for later learning difficulties. We evaluated the predictive validity of the MAP Total Score, relative to later cognitive performance and across a range of possible cut-points, in 37 preschool-aged children with prenatal drug exposure. Criterion measures were the Wechsler Preschool & Primary Scale of Intelligence-Revised (WPPSI-R), Test of Early Reading Ability-2, Peabody Picture Vocabulary Test-Revised, and Developmental Test of Visual Motor Integration. The highest predictive accuracy was demonstrated when the WPPSI-R was the criterion measure. The 14th percentile cutoff point demonstrated the highest predictive accuracy across all measures.

    Full Text Available This report describes the case of a 39-year-old male patient who presented to the emergency room with complaints of impaired balance, diplopia, and nasal voice. The patient had a history of upper respiratory tract infection. The initial physical examination revealed ataxia, ophthalmoplegia, and areflexia, which are consistent with the classic triad of Miller Fisher syndrome, considered a benign variant of Guillain-Barré syndrome. The patient developed peripheral facial paralysis during hospitalization. He underwent a treatment with immunoglobulin for five days, resulting in near complete resolution of the ataxia. However, the ophthalmoplegia and areflexia persisted. He was discharged to outpatient follow-up.

  1. Acetylcholine causes rooting in leaf explants of in vitro raised tomato (Lycopersicon esculentum Miller) seedlings.

    Bamel, Kiran; Gupta, Shrish Chandra; Gupta, Rajendra

    2007-05-30

    The animal neurotransmitter acetylcholine (ACh) induces rooting and promotes secondary root formation in leaf explants of tomato (Lycopersicon esculentum Miller var. Pusa Ruby), cultured in vitro on Murashige and Skoog's medium. The roots originate from the midrib of leaf explants and resemble taproot. ACh at 10(-5) M was found to be the optimum over a wide range of effective concentrations between 10(-7) and 10(-3) M. The breakdown products, choline and acetate were ineffective even at 10(-3) M concentration. ACh appears to have a natural role in tomato rhizogenesis because exogenous application of neostigmine, an inhibitor of ACh hydrolysis, could mimic the effect of ACh. Neostigmine, if applied in combination with ACh, potentiated the ACh effect.

    The few psychological assessment measures commercially available for the assessment of Spanish-speaking populations lack strong empirical foundation. This is concerning given the rising numbers of Spanish speakers entering the forensic and correctional systems for whom valid assessment is difficult without linguistically and culturally appropriate measures. In this study, we translated and adapted the Miller Forensic Assessment of Symptoms Test (M-FAST) into Spanish. The general purpose of this study was to investigate the psychometric, linguistic, and conceptual equivalence of the English- and Spanish-language versions of the M-FAST in a sample of 102 bilingual Hispanic incarcerated males. Participants were randomly assigned to one of three feigning conditions (honest, uncoached, or coached) and completed the M-FAST in both English and Spanish on two separate occasions. Both language versions were psychometrically, linguistically, and conceptually equivalent.

    Full Text Available Numerous reports indicate that fir woods in central and northern Europe have recently been damaged by increasing pollution. It has been demonstrated that fungi can be good bioindicators of forest health status. In polluted areas the production of fruit bodies generally declines and the fungal biodiversity, especially of symbiotic species, is reduced. Here we report the results of a survey of the fungal and plant communities in woods of Abies alba Miller in central-southern Tuscany, already studied in the past. Certain changes were observed in the study areas, but they seem more likely to be due to other factors than pollution, such as the weather conditions, the age and natural evolution of the forests towards their climax.

    Full Text Available Background: Miller-Fisher syndrome (MFS is characterized by gait ataxia, external ophtalmoplegia and areflexia and thought as an uncommon variant of Guillain Barre syndrome. Miller-Fisher syndrome is observed in about 5-8% of all Guillain Barre syndrome (GBS cases. In MFS patients, spontaneous improvement was observed in the first 3 months and these improvements were started by the 2nd week. Methods: This case was referred to physiotherapy and rehabilitation program at the 4th week since the appropriate medical treatments were unsuccessful after the attack. The patient was evaluated generally before physiotherapy program, and muscle length, strength loss, deep tendon reflexes, postural impairments and daily difficult activities and positions were assessed. Besides, the desired daily activities were identified by The Canadian Occupational Performance Measure (COPM. Treatment program was adjusted according to the patient and changes during treatment period were observed. Physiotherapy program included classical physiotherapy methods: posture correction, correction of short muscles, muscle strengthening, flexibility increase, balance/coordination, sitting and standing functions and walking improvement and climbing up stairs. Results: After the treatment, lower extremity muscle shortness decreased and muscle strength, standing on one foot duration, independent walk speed increased in time. Before treatment, he could not climbing upstairs, but it was achieved 1 year after the treatment. Berg balance score increased in time and his most desired activities by COPM (10/10 were could be performed after the treatment. Conclusion: The case improved with physiotherapy and rehabilitation program gradually with years.In the treatment of MFS patients, physiotherapy and rehabilitation being part of the treatment will be useful.

    Addressing the recent criticisms of Kvinikhidze and Miller, we prove that the spectator wave functions and currents based on ``fixed-axis'' polarization states (previously introduced by us) are Lorentz covariant, and find an explicit connection between them and conventional direction-dependent polarization states. The discussion shows explicitly how it is possible to construct pure $S$-wave models of the nucleon.

    Introduction: The main objective of adhesive dentistry is to create an effective, durable union between the tooth structure and restorative material. However, degradation of adhesive dentine interface remains largely responsible for the relatively short lifetime of tooth colored resin restoration. Aim: The aim of the study is to compare the dentin collagen stabilization property of Chlorhexidine (CHX) and Aloe barbadensis Miller using shear bond strength testing. Materials and Methods: Occlusal reduction was done in sixty extracted human mandibular molars to expose the mid coronal dentin and divided into three groups n = 20. Following the surface pretreatment (Group 1 = control, Group 2 = CHX, Group 3 = Aloevera), dentine bonding agent and composite resin were applied and cured. The specimens were then subjected to shear bond strength testing. Results: From the results analyzed, it was noted that there was statistically significant difference between the groups Control and CHX and Control and A. barbadensis Miller (P 0.05). Hence, the following result for the shear bond strengths to dentin was obtained: Control < CHX ≈ A. barbadensis Miller. Conclusion: CHX and A. barbadensis Miller, as pretreatment agents of acid demineralized dentin collagen, has no adverse effect on the immediate shear bond strength of a two-step etch and rinse adhesive to dentin.

    Ureilite meteorites are partially melted asteroidal-peridotite residues, or more rarely, cumulates that can contain greater than three weight percent carbon. Here we describe an exceptional C-rich lithology, composed of 34 modal % large (up to 0.8 mm long) crystalline graphite grains, in the Antarctic ureilite meteorite Miller Range (MIL) 091004. This C-rich lithology is embedded within a silicate region composed dominantly of granular olivine with lesser quantities of low-Ca pyroxene, and minor FeNi metal, high-Ca pyroxene, spinel, schreibersite and troilite. Petrological evidence indicates that the graphite was added after formation of the silicate region and melt depletion. Associated with graphite is localized reduction of host olivine (Fo88-89) to nearly pure forsterite (Fo99), which is associated with FeNi metal grains containing up to 11 wt.% Si. The main silicate region is typical of ureilite composition, with highly siderophile element (HSE) abundances ∼0.3 × chondrite, 187Os/188Os of 0.1260-0.1262 and Δ17O of -0.81 ± 0.16‰. Mineral trace-element analyses reveal that the rare earth elements (REE) and the HSE are controlled by pyroxene and FeNi metal phases in the meteorite, respectively. Modeling of bulk-rock REE and HSE abundances indicates that the main silicate region experienced ∼6% silicate and >50% sulfide melt extraction, which is at the lower end of partial melt removal estimated for ureilites. Miller Range 091004 demonstrates heterogeneous distribution of carbon at centimeter scales and a limited range in Mg/(Mg + Fe) compositions of silicate grain cores, despite significant quantities of carbon. These observations demonstrate that silicate rim reduction was a rapid disequilibrium process, and came after silicate and sulfide melt removal in MIL 091004. The petrography and mineral chemistry of MIL 091004 is permissive of the graphite representing late-stage C-rich melt that pervaded silicates, or carbon that acted as a lubricant during

    Full Text Available Abstract Background Home visiting programs comprising intensive and sustained visits by professionals (usually nurses over the first two years of life show promise in promoting child health and family functioning, and ameliorating disadvantage. Australian evidence of the effectiveness of sustained nurse home visiting in early childhood is limited. This paper describes the method and cohort characteristics of the first Australian study of sustained home visiting commencing antenatally and continuing to child-age two years for at-risk mothers in a disadvantaged community (the Miller Early Childhood Sustained Home-visiting trial. Methods and design Mothers reporting risks for poorer parenting outcomes residing in an area of socioeconomic disadvantage were recruited between February 2003 and March 2005. Mothers randomised to the intervention group received a standardised program of nurse home visiting. Interviews and observations covering child, maternal, family and environmental issues were undertaken with mothers antenatally and at 1, 12 and 24 months postpartum. Standardised tests of child development and maternal-child interaction were undertaken at 18 and 30 months postpartum. Information from hospital and community heath records was also obtained. Discussion A total of 338 women were identified and invited to participate, and 208 were recruited to the study. Rates of active follow-up were 86% at 12 months, 74% at 24 months and 63% at 30 months postpartum. Participation in particular data points ranged from 66% at 1 month to 51% at 24 months postpartum. Rates of active follow-up and data point participation were not significantly different for the intervention or comparison group at any data point. Mothers who presented for antenatal care prior to 20 weeks pregnant, those with household income from full-time employment and those who reported being abused themselves as a child were more likely to be retained in the study.

    Abstract Karyological investigations were carried out on four species of Bellevalia Lapeyrouse, 1808 and Muscari Miller, 1758 (Asparagaceae) sampled in contrasting bioclimatic conditions of Algeria. The endemic Bellevalia mauritanica Pomel, 1874 was found to have a tetraploid cytotype 2n = 4x = 16 and an octoploid 2n = 8x = 32 which is a new report. The chromosome number 2n = 2x = 18 in Muscari comosum (Linnaeus, 1753) Miller, 1768 and Muscari maritimum Desfontaines, 1798 was in conformity with earlier reports. The latter species reveals a lesser bimodality of the karyotype. Within Muscari neglectum Gussone ex Tenore, 1842 pentaploid (2n = 5x = 45), hexaploid (2n = 6x = 54) and very rare octoploid cytotype (2n = 8x = 72) have been reported in Algeria. Principal component analysis performed on basis of karyotype parameters, showed a segregation of the different cytotypes. This study provides new karyological information, which is discussed in a taxonomic context. PMID:27186346

    Full Text Available The carnauba (Copernicia prunifera (Miller HE Moore is a native fruit species to the north- east of Brazil and its exploration is based mainly on the extract of wax powder from leaves. The objective of this study was to evaluate the effect of different management strategies of cutting leaves, developmental stages and leaf age on leaf traits and physical-chemical attributes of carnauba wax in a natural population of carnauba palm located at the Cajazeira Farm, municipality of União, Piauí state, Brazil. The selected plants were identi- fied and classified in two developmental stages: capoteiro and adult palm. The management strategies cutting leaves were: one cut in August; two cuts, the first in August and the second in December; and one cut in De- cember. The leaves were separated according to age into new and old leaf. It was performed the individual analysis of variance of leaf number (LN, wax powder production (WP, ratio WP/LN, moisture content, impu- rities content and wax yield for each management systems as well as the analysis of the different managements. Leaf age presented as the attribute of greater relevance in the commercial use of carnauba. The best manage- ment strategy for cutting leaves of carnauba consists of a single annual cut in December.

  20. On the Miller-Tucker-Zemlin Based Formulations for the Distance Constrained Vehicle Routing Problems

    Vehicle Routing Problem (VRP), is an extension of the well known Traveling Salesman Problem (TSP) and has many practical applications in the fields of distribution and logistics. When the VRP consists of distance based constraints it is called Distance Constrained Vehicle Routing Problem (DVRP). However, the literature addressing on the DVRP is scarce. In this paper, existing two-indexed integer programming formulations, having Miller-Tucker-Zemlin based subtour elimination constraints, are reviewed. Existing formulations are simplified and obtained formulation is presented as formulation F1. It is shown that, the distance bounding constraints of the formulation F1, may not generate the distance traveled up to the related node. To do this, we redefine the auxiliary variables of the formulation and propose second formulation F2 with new and easy to use distance bounding constraints. Adaptation of the second formulation to the cases where new restrictions such as minimal distance traveled by each vehicle or other objectives such as minimizing the longest distance traveled is discussed.

    Various analogues of Titan haze particles (termed ‘tholins’) have been made in the laboratory. In certain geologic environments on Titan, these haze particles may come into contact with aqueous ammonia (NH3) solutions, hydrolyzing them into molecules of astrobiological interest. A Titan tholin analogue hydrolyzed in aqueous NH3 at room temperature for 2.5 years was analyzed for amino acids using highly sensitive ultra-high performance liquid chromatography coupled with fluorescence detection and time-of-flight mass spectrometry (UHPLC-FD/ToF-MS) analysis after derivatization with a fluorescent tag. We compare here the amino acids produced from this reaction sequence with those generated from room temperature Miller-Urey (MU) type electric discharge reactions. We find that most of the amino acids detected in low temperature MU CH4/N2/H2O electric discharge reactions are generated in Titan simulation reactions, as well as in previous simulations of Triton chemistry. This argues that many processes provide very similar mixtures of amino acids, and possibly other types of organic compounds, in disparate environments, regardless of the order of hydration. Although it is unknown how life began, it is likely that given reducing conditions, similar materials were available throughout the early Solar System and throughout the universe to facilitate chemical evolution.

    We designed and conducted a series of primordial-soup Miller-Urey style experiments with deuterated gases and reagents to compare the spark-discharge products of a "deuterated world" with the standard reaction in the "hydrogenated world". While the deuteration of the system has little effect on the distribution of amino acid products, significant differences are seen in other regions of the product-space. Not only do we observe about 120 new species, we also see significant differences in their distribution if the two hydrogen isotope worlds are compared. Several isotopologue matches can be identified in both, but a large proportion of products have no equivalent in the corresponding isotope world with ca. 43 new species in the D world and ca. 39 new species in the H world. This shows that isotopic exchange (the addition of only one neutron) may lead to significant additional complexity in chemical space under otherwise identical reaction conditions. © 2017 The Authors.

    Endophytic fungi were isolated from healthy leaves of Indigofera suffruticosa Miller, a medicinal plant found in Brazil which is used in folk medicine to treat various diseases. Among 65 endophytic fungi isolated, 18 fungi showed activity against at least one tested microorganism in preliminary screening, and the best results were obtained with Nigrospora sphaerica (URM-6060) and Pestalotiopsis maculans (URM-6061). After fermentation in liquid media and in semisolid media, only N. sphaerica demonstrated antibacterial activity (in Potato Dextrose Broth-PDB and in semisolid rice culture medium). In the next step, a methanolic extract from rice culture medium (NsME) and an ethyl acetate extract (NsEAE) from the supernatant of PDB were prepared and both exhibited antimicrobial activity against Gram-negative and Gram-positive bacteria. The best result was observed against Staphylococcus aureus, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 1.56 mg/mL and 6.25 mg/mL, respectively, for NsME and MIC and MBC values of 0.39 mg/mL and 3.12 mg/mL, respectively, for NsEAE. This study is the first report about the antimicrobial activity of endophytic fungi residing in I. suffruticosa leaves, in which the fungus N. sphaerica demonstrated the ability to produce bioactive agents with pharmaceutical potential, and may provide a new lead in the pursuit of new biological sources of drug candidates.

    Stanley Miller's 1958 H2S-containing experiment, which included a simulated prebiotic atmosphere of methane (CH4), ammonia (NH3), carbon dioxide (CO2), and hydrogen sulfide (H2S) produced several alkyl amino acids, including the alpha-, beta-, and gamma-isomers of aminobutyric acid (ABA) in greater relative yields than had previously been reported from his spark discharge experiments. In the presence of H2S, aspariic and glutamic acids could yield alkyl amino acids via the formation of thioimide intermediates. Radical chemistry initiated by passing H2S through a spark discharge could have also enhanced alkyl amino acid synthesis by generating alkyl radicals that can help form the aldehyde and ketone precursors to these amino acids. We propose mechanisms that may have influenced the synthesis of certain amino acids in localized environments rich in H2S and lightning discharges, similar to conditions near volcanic systems on the early Earth, thus contributing to the prebiotic chemical inventory of the primordial Earth.

    Miners and millers of talc ore, free from asbestos and silica, were examined for respiratory effects. A study of 116 subjects included the modified British Medical Research Council respiratory symptom questionnaire, simple spirometry, chest radiography, and limited examination of the chest. A one-year follow-up evaluation was performed on 103 subjects. Of the 12 subjects whose chest radiographs showed small round or irregular opacities (perfusion 1/0 or greater), five had never smoked cigarettes. Pulmonary function values at the time of the initial study were less than predicted and the rates of loss of FEV1 and FVC greater than expected. These differences were in part attributed to cigarette smoking but were greater than predicted from that source alone. There was evidence of an exposure effect after adjusting for cigarette smoking and we conclude that these workers have been affected by their exposures. No clear interaction between smoking and exposure could be identified. Populations such as this will need to be studied for longer periods to determine what current dust levels are safe.

    Miller Fisher Syndrome (MFS) is a rare variant of Guillain-Barré Syndrome (GBS) that has a geographically variable incidence. It is largely a clinical diagnosis based on the cardinal clinical features of ataxia, areflexia, and opthalmoplegia, however, other neurological signs and symptoms may also be present. Serological confirmation with the anti-GQ1b antibody is available and allows for greater diagnostic certainty in the face of confounding symptoms. A self-limiting course is typical of MFS. The following case report is that of a patient who presented with generalized weakness, somatic pain, inability to walk, and diplopia following an upper respiratory illness. The patient exhibited the classic triad of ataxia, areflexia, and opthalmoplegia characteristic of MFS, but also had less typical signs and symptoms making for a more challenging diagnostic workup. Our suspected diagnosis of MFS was serologically confirmed with positive anti-GQ1b antibody titer and the patient was successfully treated with Intravenous immune globulin (IVIG).

    Two Warsaw medical students, Jerzy Konorski and Stefan Miller, having read I.P. Pavlov's works on conditional reflexes, informed him in a 1928 letter that they had discovered a new type of conditioning. A previously neutral stimulus preceded the passive lifting of a dog's paw which then was followed by feeding; this stimulus then evoked the spontaneous raising of that paw. Pavlov responded informing them that their conditioning of motor responses expanded his theory of higher nervous activity, but that their conditioning paradigm-that they named CRII-did not differ fundamentally from the Pavlovian conditioning paradigm. The replication of the Warsaw experiment in Pavlov's laboratory failed to provide unequivocal results. From 1931 to 1933, Konorski, working in Pavlov's Leningrad laboratory, further explored the parameters of CRII. Pavlov insisted that the conditioning of motor movements differs from the conditioning of other sensory analyzers only in that, on the neural level, the motor analyzer is both afferent, that is, perceptive, and efferent, that is, responsive. Konorski was not convinced, and he subsequently maintained that the two conditioning paradigms were fundamentally different.

    The geometric and electronic structure of catalytically relevant molybdenum carbide phases (cubic δ-MoC, hexagonal α-MoC, and orthorhombic β-Mo2C) and their low Miller-index surfaces have been investigated by means of periodic density functional theory (DFT) based calculations with the Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. Comparison to available experimental data indicates that this functional is particularly well suited to study these materials. The calculations reveal that β-Mo2C has a stronger metallic character than the other two polymorphs, both β-Mo2C and δ-MoC have a large ionic contribution, and δ- and α-MoC exhibit the strongest covalent character. Among the various surfaces explored, the calculations reveal the high stability of the δ-MoC(001) nonpolar surface, Mo- and C-terminated (001) polar surfaces of α-MoC, and the nonpolar (011) surface of β-Mo2C. A substantially low work function of only 3.4 eV is predicted for β-Mo2C(011), suggesting that this system is particularly well suited for (electro)catalytic processes where surface → adsorbate electron transfer is essential. The overall implications for heterogeneously catalysed reactions by these molybdenum carbide nanoparticles are also discussed.

    The effect of topical application of Aloe Vera (Aloe barbadensis Miller) extract was assessed on the healing of rat oral wounds in an in vivo model using 72 male Wistar rats divided into three groups (n = 24): control, placebo and Aloe Vera (0.5% extract hydroalcoholic). Traumatic ulcers were caused in the dorsum of the tongue using a 3-mm punch tool. The Aloe Vera and placebo group received two daily applications. The animals were sacrificed after 1, 5, 10 and 14 days. Clinical analysis (ulcer area and percentage of repair) and histopathological analysis (degree of re-epithelialization and inflammation) were performed. The comparison of the differences between scores based on group and experimental period, both in quantitative and semi-quantitative analyses, was performed using the Kruskal-Wallis test. The significance level was 5%. On day 1, all groups showed predominantly acute inflammatory infiltrate. On day 5, there was partial epithelialization and chronic inflammatory infiltrate. On the days 10 and 14 total repair of ulcers was observed. There was no significant difference between groups in the repair of mouth ulcers. It is concluded that treatment using Aloe Vera as an herbal formulation did not accelerate oral wound healing in rats.

    There is a singular unifying reality underlying every biologic interaction on our planet. In immunology, that which does not kill you makes you different. -William B. Miller, Jr. We are experiencing a revolution in our understanding of inner space on a par with our exponentially increasing understanding of outer space. In biology, we are learning that the genetic and epigenetic complexity within organisms is far deeper than suspected. This is a key theme in William B. Miller Jr.'s book, The Microcosm Within: Evolution and Extinction in the Hologenome. We are learning also that a focus on the human genome alone is misleading when it comes to who we really are as biological entities, and in terms of how we and other creatures have evolved. Rather than being defined by the human genome alone, we are instead defined by the "hologenome," the sum of the human genome and the far larger genetic endowment of the microbiome and symbiotic communities that reside within and around us. Miller is a medical doctor previously in private practice in Pennsylvania and Phoenix, Arizona. This book is his first foray into evolutionary theory. His book could have been titled "The Origin of Variation" because this is his primary focus. He accepts that natural selection plays a role in evolution, but he demotes this mechanism to a less important role than the Modern Synthesis suggests. His main gripe, however, concerns random variation. He argues that random variation is unable to explain the origin and evolution of biological forms that we see in the world around us and in the historical record. Miller suggests that, rather than random variation as the engine of novelty, there is a creative impulse at the heart of cellular life, and even at the level of the genetic aggregate, that generates novelty on a regular basis. I probe this assertion in the interview below. He also highlights the strong role of "exogenous genetic assault" in variation and in his immunological model of evolution.

    Full Text Available Patients with diseased teeth, or those who are difficult to intubate, have a higher risk of dental injury during laryngoscopy. We report 3 cases of smooth endotracheal intubation using a paraglossal technique with a straight Miller blade in patients with poor dentition. Three patients with poor dentition were scheduled to undergo surgery under general anesthesia. All patients presented with extremely loose upper central incisors and had lost the other right upper teeth, while micrognathia and prominent, loose upper incisors were noted in 1 case. We elected to use a straight Miller blade using a paraglossal approach. A nasopharyngeal airway was inserted after induction of general anesthesia to facilitate mask ventilation and prevent air leakage from the mask. The Miller blade was then inserted from the right corner of the mouth, avoiding contact with the vulnerable incisors, and advanced along the groove between the tongue and tonsil. The endotracheal tube was subsequently smoothly inserted after obtaining a grade 1 Cormack and Lehane view without dental trauma in all 3 cases. Direct laryngoscopy using the paraglossal straight blade technique avoids dental damage in patients with mobile upper incisors and no right maxillary molars. It is a practical alternative method that differs from the traditional Macintosh laryngoscope in patients with a high risk of dental injury during the procedure. This technique, which provides an improved view of the larynx, might also be helpful with patients in whom intubation is difficult.

    Primitive carbonaceous chondrites contain a wide variety of organic material, ranging from soluble discrete molecules to insoluble, unstructured kerogen-like components, as well as structured nano-globules of macromolecular carbon. The relationship between the soluble organic molecules, macromolecular organic material, and host minerals are poorly understood. Due to the differences in extractability of soluble and insoluble organic materials, the analysis methods for each differ and are often performed independently. The combination of soluble and insoluble analyses, when performed concurrently, can provide a wider understanding of spatial distribution, and elemental, structural and isotopic composition of organic material in primitive meteorites. Using macroscale extraction and analysis techniques in combination with in situ microscale observation, we have been studying both insoluble and soluble organic material in the primitive CR2 chondrite Miller Range (MIL) 090657. In accompanying abstracts (Cao et al. and Messenger et al.) we discuss insoluble organic material in the samples. By performing the consortium studies, we aim to improve our understanding of the relationship between the meteorite minerals and the soluble and insoluble organic phases and to delineate which species formed within the meteorite and those that formed in nebular or presolar environments. In this abstract, we present the results of amino acid analyses of MIL 090657 by ultra performance liquid chromatography with fluorescence detection and quadrupole-time of flight mass spectrometry. Amino acids are of interest because they are essential to life on Earth, and because they are present in sufficient structural, enantiomeric and isotopic diversity to allow insights into early solar system chemical processes. Furthermore, these are among the most isotopically anomalous species, yet at least some fraction are thought to have formed by aqueously-mediated processes during parent body alteration.

    Full Text Available Aloe barbadensis Miller (Aloe vera has a Crassulaceae acid metabolism which grants the plant great tolerance to water restrictions. Carbohydrates such as acemannans and fructans are among the molecules responsible for tolerating water deficit in other plant species. Nevertheless, fructans, which are prebiotic compounds, have not been described nor studied in Aloe vera, whose leaf gel is known to possess beneficial pharmaceutical, nutritional and cosmetic properties. As Aloe vera is frequently cultivated in semi-arid conditions, like those found in northern Chile, we investigated the effect of water deficit on fructan composition and structure. For this, plants were subjected to different irrigation regimes of 100%, 75%, 50% and 25% field capacity (FC. There was a significant increase in the total sugars, soluble sugars and oligo and polyfructans in plants subjected to water deficit, compared to the control condition (100% FC in both leaf tips and bases. The amounts of fructans were also greater in the bases compared to the leaf tips in all water treatments. Fructans also increase in degree of polymerization with increasing water deficit. Glycosidic linkage analyses by GC-MS, led to the conclusion that there are structural differences between the fructans present in the leaves of control plants with respect to plants irrigated with 50% and 25% FC. Therefore, in non-stressed plants, the inulin, neo-inulin and neo-levan type of fructans predominate, while in the most stressful conditions for the plant, Aloe vera also synthesizes fructans with a more branched structure, the neofructans. To our knowledge, the synthesis and the protective role of neo-fructans under extreme water deficit has not been previously reported.

    Using an approximate evaluation of Miller's golden rule formula to calculate autoionization widths which allows for the consideration only of L/sup 2/ functions, the positions and lifetimes of the lowest /sup 1/,/sup 3/P autoionizing states of He have been obtained to reasonable accuracy. This method has been extended to molecular problems, and the ab initio configuration interaction potential energy and width surfaces for the He(2/sup 3/S) + H/sub 2/ system have been obtained. Quantum mechanical close-coupling calculations of ionization cross sections using the complex V* - (i/2) GAMMA-potential have yielded rate constants in good agreement with the experimental results of Lindinger, et al. The potential energy surface of the He(2/sup 1/S) + H/sub 2/ system has also been obtained and exhibits not only a high degree of anisotropy, but also contains a relative maximum for a perpendicular (C/sub 2//sub v/) approach which appears to arise from s-p hybridization of the outer He orbital. However, similar ab initio calculations on the He(2/sup 1/S) + Ar system do not show such anomalous structure. In addition, the complex poles of the S-matrix (Siegert eigenvalues) were calculated for several autoionizing states of He and H/sup -/, with encouraging results even for quite modest basis sets. This method was extended to molecular problems, and results obtained for the He(2/sup 3/S) + H and He(2/sup 1/S) + H systems. 75 references.

  6. On the adiabatic representation of Meyer-Miller electronic-nuclear dynamics.

    The Meyer-Miller (MM) classical vibronic (electronic + nuclear) Hamiltonian for electronically non-adiabatic dynamics-as used, for example, with the recently developed symmetrical quasiclassical (SQC) windowing model-can be written in either a diabatic or an adiabatic representation of the electronic degrees of freedom, the two being a canonical transformation of each other, thus giving the same dynamics. Although most recent applications of this SQC/MM approach have been carried out in the diabatic representation-because most of the benchmark model problems that have exact quantum results available for comparison are typically defined in a diabatic representation-it will typically be much more convenient to work in the adiabatic representation, e.g., when using Born-Oppenheimer potential energy surfaces (PESs) and derivative couplings that come from electronic structure calculations. The canonical equations of motion (EOMs) (i.e., Hamilton's equations) that come from the adiabatic MM Hamiltonian, however, in addition to the common first-derivative couplings, also involve second-derivative non-adiabatic coupling terms (as does the quantum Schrödinger equation), and the latter are considerably more difficult to calculate. This paper thus revisits the adiabatic version of the MM Hamiltonian and describes a modification of the classical adiabatic EOMs that are entirely equivalent to Hamilton's equations but that do not involve the second-derivative couplings. The second-derivative coupling terms have not been neglected; they simply do not appear in these modified adiabatic EOMs. This means that SQC/MM calculations can be carried out in the adiabatic representation, without approximation, needing only the PESs and the first-derivative coupling elements. The results of example SQC/MM calculations are presented, which illustrate this point, and also the fact that simply neglecting the second-derivative couplings in Hamilton's equations (and presumably also in the Schr

    2014-07-01

    Full Text Available Background: A rare clinical variant of Guillain-Barre syndrome, known as Miller Fisher syndrome (MFS, is an immunemediated neuropathy classically characterized by a triad consisting of ophthalmoplegia, ataxia, and areflexia.1,2 Although MFS is thought to be a disease of immunological basis, other pathological entities may give rise to the syndrome as well. The diagnosis of MFS relies upon clinical signs, a combination of lab tests including antibody serum, cerebrospinal fluid, and electrophysiological findings. Understanding the clinical course of MFS and its ocular components can aid in the rehabilitation and co-management of these patients. Case Report: A 79-year-old white male presented with a four day onset of double vision and an inability to walk unassisted. An examination revealed a pupil-sparing third-nerve palsy with a left eye ptosis. Due to the patient being in moderate pain throughout his entire body and presenting with an acute onset of symptoms, the patient was sent to the emergency room in the same hospital building. The patient was immediately admitted for evaluation and testing which revealed the diagnosis of MFS. Conclusions: Although a complaint of diplopia can lead to an array of diagnoses, when accompanied by an acute inability to walk, MFS should be on the list of possible causes. Although mostly a self-limiting disease, there is the possibility of progressing to respiratory failure. Knowledge of the syndrome, its clinical course, and prognosis, along with an appropriate evaluation with current laboratory testing, will lead to the proper diagnosis, treatment, and management.

    Sideritis italica (Miller) Greuter et Burdet is a widespread Lamiacea in the Mediterranean region used in traditional medicine. Essential oils were antibacterial against nine ATCC and as many clinically isolated Gram-positive and Gram-negative bacterial strains. Antibacterial activity was also found against Helicobacter pylori: a dose-dependant inhibition was shown between 5 and 25 microg/ml. The antibacterial activity of the oils was expressed as MICs (minimum inhibitory concentrations) and MBCs (minimum bactericidal concentrations). At a concentration between 3.9 and 250 microg/ml the oils showed a significant antibacterial effect against both Gram-negative and Gram-positive bacteria. In particular the ATCC strains Pseudomonas aeruginosa (MIC=3.9 microg/ml and 7.8 for flowerheads and leaves, respectively), Proteus mirabilis (MIC=15.6 and 7.8 microg/ml), Salmonella typhi (MIC=7.8 microg/ml) and Proteus vulgaris (MIC=15.6 microg/ml) were the most inhibited. Only Pseudomonas aeruginosa showed MBC at a concentration between 62.6 and 125 microg/ml. The antioxidant activity of the essential oils was evaluated by two cell free colorimetric methods: ABTS and DMPD; leaf oil is more active (4.29 +/- 0.02 trolox equivalents and 4.53 +/- 0.67 ascorbic acid equivalents by ABTS and DMPD, respectively). Finally the antioxidant activity of the essential oils was also evaluated by their effects on human whole blood leukocytes (WB) and on isolated polymorphonucleate (PMN) chemiluminescence. Comparing the effects of the oils from leaves and flowerheads on both PMN and WB chemiluminescence emission, we found no significant differences. Essential oils showed a dose-dependent and linear inhibitory activity on isolated PMN as well as on WB CL emission when PMA-stimulated. On the contrary, the inhibitory activity on resting cells was nonlinear. Our data represent an answer to the continual demand for new antibiotics and antioxidants for the continuous emergence of antibiotic

    The Miller-Urey Experiment in space (MUE) investigates the formation of potential prebiotic organic compounds in the early solar system environment. The MUE experiment will be sent to and retrieved from the International Space Station (ISS), where it will be performed inside the Microgravity Science Glovebox (MSG). The goal of this space experiment is to understand prebiotic reactions in microgravity by simulating environments of the early solar nebula. The dynamic environment of the solar nebula with the simultaneous presence of gas, particles, and energetic processes, including shock waves, lightning, and radiation may trigger a rich organic chemistry leading to organic molecules. These environments will be simulated in six fabricated vials containing various gas mixtures as well as solid particles. Two gas mixture compositions will be tested and subjected to continuous spark discharges for 48, 96, and 192 hours. Silicate particles will serve as surfaces on which thin water ice mantles can accrete. The particles will move repeatedly through a high-voltage spark discharge in microgravity, enabling chemical re-actions analogous to the original Miller-Urey experiment. The experiment will be performed at low temperatures (-5 C), slowing hydrolysis and improving chances of detection of interme-diates, initial products, and their distributions. Executing the Miller-Urey experiment in the space environment (microgravity) allows us to simulate conditions that could have prevailed in the energetic early solar nebula and provides insights into the chemical pathways that may occur in forming planetary systems. Analysis will be performed post-flight using chemical analytical methods. The anticipated results will provide information about chemical reaction pathways to form organic compounds in space environment, emphasizing abiotic chemical pathways and mechanisms that could have been crucial in the formation of biologically relevant compounds such as amino acids and

    2013-05-01

    The synthesis of amino acids in the Miller-Urey spark-discharge experiments in the early 1950s inspired a strong interest in experimental studies of prebiotic organic chemistry that continues today. Over the years, many of the basic building blocks of life as we know it have been synthesized in the laboratory from simple ingredients, including amino acids, sugars, nucleobases, and membrane-forming lipids. Questions remain, however, concerning whether the conditions that allow synthesis of these compounds in the laboratory accurately simulate those that might have been present on the early Earth, and a closer convergence between plausible prebiotic conditions and laboratory simulations remains a challenge for experimentalists.

    Archived samples from a previously unreported 1958 Stanley Miller electric discharge experiment containing hydrogen sulfide (H2S) were recently discovered and analyzed using high-performance liquid chromatography and time-of-flight mass spectrometry. We report here the detection and quantification of primary amine-containing compounds in the original sample residues, which were produced via spark discharge using a gaseous mixture of H2S, CH4, NH3, and CO2. A total of 23 amino acids and 4 amines, including 7 organosulfur compounds, were detected in these samples. The major amino acids with chiral centers are racemic within the accuracy of the measurements, indicating that they are not contaminants introduced during sample storage. This experiment marks the first synthesis of sulfur amino acids from spark discharge experiments designed to imitate primordia! environments. The relative yield of some amino acids, in particular the isomers of aminobutyric acid, are the highest ever found in a spark discharge experiment. The simulated primordial conditions used by Miller may serve as a model for early volcanic plume chemistry and provide insight to the possible roles such plumes may have played in abiotic organic synthesis. Additionally, the overall abundances of the synthesized amino acids in the presence of H2S are very similar to the abundances found in some carbonaceous meteorites, suggesting that H2S may have played an important role in prebiotic reactions in early solar system environments.

  20. Counterpoint to “What Is an Epileptic Seizure?” By D’Ambrosio and Miller

    Science.gov (United States)

    Dudek, F Edward; Bertram, Edward H

    2010-01-01

    D’Ambrosio and Miller argue that brief (i.e., one to a few seconds), rhythmic electrographic events accompanied by behavioral arrest, which they have observed in rats after lateral fluid percussion (i.e., in an animal model of traumatic brain injury), should be considered seizures in this model of posttraumatic epilepsy (1). A counter argument is that these events are not characteristic of the seizures seen clinically in posttraumatic epilepsy or in other forms of acquired epilepsy. Furthermore, several types of brief, rhythmic activity can be recorded in the electroencephalogram (EEG) of animals and humans without epilepsy. One cannot exclude the possibility that such events represent normal electrical activity, which may (or even may not) occur more often after brain injury. Thus, caution is required. In this counterpoint to “What Is an Epileptic Seizure?” by D’Ambrosio and Miller, the assertion is made that experimental studies on animal models of acquired epilepsy that claim electrographic events to be seizures, when the possibility exists that they may not be seizures characteristic of human acquired epilepsy, could be counterproductive, since research resources could be focused on animal models that may not actually demonstrate acquired epilepsy.

  3. The effects of discontinuities in the Betts Miller cumulus convection scheme on four-dimensional variational data assimilation

    1993-10-01

    A tangent linear and an adjoint of the large-scale precipitation and the cumulus convection processes in the National Meteorological Center's NMC/ETA regional forecast model are developed. The effects of discontinuities in the Betts Miller cumulus convection scheme are examined and applicability of derivative minimization methods in four-dimensional variational (4D VAR) data assimilation is considered. It is demonstrated that discontinuities present in the control Betts Miller cumulus convection scheme increase linearization errors to a large extent and have adverse effects on 4D VAR data assimilation. In the experiments performed, discontinuities in the cumulus convection scheme have the most serious effect in low layers. These problems can be reduced by modifying the scheme to make it more continuous in low layers. Positive effects of inclusion of cumulus convection in 4D VAR data assimilation are found in upper layers, especially in humidity fields. The "observations" used are optimal interpolation analyses of temperature, surface pressure, wind and specific humidity. By inclusion of other data, more closely related to the convective processes, such as precipitation and clouds, more benefits should be expected. Even with the difficulties caused by discontinuities, derivative minimization techniques appear to work for the data assimilation problems. In order to get more general conclusions, more experiments are needed with different synoptic situations. The inclusion of other important physical processes such as radiation, surface friction and turbulence in the forecast and the corresponding adjoint models could alter the results since they may reinforce the effects of discontinuities.

  4. Schwann cells are activated by ATP released from neurons in an in vitro cellular model of Miller Fisher syndrome

    Full Text Available The neuromuscular junction is exposed to different types of insult, including mechanical trauma, toxins and autoimmune antibodies and, accordingly, has retained through evolution a remarkable ability to regenerate. Regeneration is driven by multiple signals that are exchanged among the cellular components of the junction. These signals are largely unknown. Miller Fisher syndrome is a variant of Guillain–Barré syndrome caused by autoimmune antibodies specific for epitopes of peripheral axon terminals. Using an animal model of Miller Fisher syndrome, we recently reported that a monoclonal anti-polysialoganglioside GQ1b antibody plus complement damages nerve terminals with production of mitochondrial hydrogen peroxide, which activates Schwann cells. Several additional signaling molecules are likely to be involved in the activation of the regeneration program in these cells. Using an in vitro cellular model consisting of co-cultured primary neurons and Schwann cells, we found that ATP is released by neurons injured by the anti-GQ1b antibody plus complement. Neuron-derived ATP acts as an alarm messenger for Schwann cells, where it induces the activation of intracellular pathways, including calcium signaling, cAMP and CREB, which, in turn, produce signals that promote nerve regeneration. These results contribute to defining the cross-talk taking place at the neuromuscular junction when it is attacked by anti-gangliosides autoantibodies plus complement, which is crucial for nerve regeneration and is also likely to be important in other peripheral neuropathies.

    2014-01-01

    Daisy Miller, among Henry James’masterpieces, is the novella which won him international fame. As some critics have analyzed, Daisy is a victim of the values of the Old World. In the author’s opinion, Daisy’s tragedy should be partly attrib-uted to prejudice, which impedes the international communication between the newly wealthy Americans and the Europeanized Americans. In this sense, this paper focuses on an analysis of three forms of prejudice in Daisy Miller and tries to interpret Daisy’s tragic destiny from the perspective of intercultural communication.

    In this study, the essential oil and the phenolic composition along with the antioxidant activity of R. officinalis L. and S. fruticosa Miller, collected in Zakynthos island (Ionian Sea, Greece), were investigated. The essential oil composition of the plants was characterized by the presence of 1,8-cineole. Mean values of the antioxidant activities of rosemary and sage essential oils indicated slight differences. The antioxidant activity of sage oil was correlated with the oxygenated sesquiterpenes and diterpenes concentrations. Concerning the methanolic extracts, a close relationship between the phenolic content and the development stage during vegetative cycle of these plants was observed. The identified flavonoids, except rutin, seemed to increase with the advancement of developmental stages, while phenolic acids followed an opposite pattern. The antioxidant activity was correlated with the amount of total phenolic content.

    Nicotine promotes rooting in leaf explants of tomato (Lycopersicon esculentum Miller var. Pusa Ruby). Nicotine at 10(-9) to 10(-3) M concentrations was added to the MS basal medium. The optimum response (three-fold increase in rooting) was obtained at 10(-7) M nicotine-enriched MS medium. At the same level i.e. 10(-7) M Nicotine induced dramatic increase (11-fold) in the number of secondary roots per root. We have shown earlier that exogenous acetylcholine induces a similar response in tomato leaves. Since nicotine is an agonist of one of the two acetylcholine receptors in animals, its ability to simulate ACh action in a plant system suggests the presence of the same molecular mechanism operative in both, animal and plant cells.

  14. Accounting for Non-Represented Heterogeneity in Soil Water Flow by Estimating Miller Scaling Fields with Ensemble Kalman Filter

    Science.gov (United States)

    Bauser, H. H.; Jaumann, S.; Roth, K.

    2015-12-01

    The Ensemble Kalman Filter (EnKF) is a widely used data assimilation method in soil hydrology to estimate states and parameters, incorporating uncertainties in measurements and all model components.Of these components not only states and parameters, but also the representation of small scale heterogeneities of different soil layers suffers from large uncertainties. This is particularly severe when measuring soil water content, which reflects the soil's local texture and is typically discontinuous across heterogeneity boundaries. To address this challenge we enhance the EnKF to simultaneously also estimate a Miller scaling field for each soil layer.The enhanced EnKF is tested with a one-dimensional water content data set based on time domain reflectometry (TDR) measurements and leads to an improved consistency of model and measurements.

  15. Understanding the Larson-Miller parameter. [for extrapolating stress rupture and creep properties of steels and superalloys

    Furillo, F. T.; Purushothaman, S.; Tien, J. K.

    1977-01-01

    The Larson-Miller (L-M) method of extrapolating stress rupture and creep results is based on the contention that the absolute temperature-compensated time function should have a unique value for a given material. This value should depend only on the applied stress level. The L-M method has been found satisfactory in the case of many steels and superalloys. The derivation of the L-M relation is discussed, taking into account a power law creep relationship considered by Dorn (1965) and Barrett et al. (1964), a correlation expression reported by Garofalo et al. (1961), and relations concerning the constant C. Attention is given to a verification of the validity of the considered derivation with the aid of suitable materials.

    2003-01-01

    The aim of this study was to investigate the accuracy and transferability of near-infrared (NIR) calibrations for estimating the content and composition of the volatile fraction in fennel fruits (Foeniculum vulgare Miller) as an example of medicinal and spice plants. A master calibration with spectra obtained on a scanning monochromator was generated using 345 samples from three different harvests (1997-1999). A subset of 70 samples from 1999 was also measured on a dispersive grating and a scanning diode array system to gain an insight into the influence of sample presentation and scanning techniques. For all instruments, calibrations with standard errors in the range of the reference method were achieved. Furthermore the influence of storage on NIR spectra and, additionally, the potential of transferring spectra between both scanning monochromators was studied.

  17. Risk and efficacy of human-enabled interspecific hybridization for climate-change adaptation: Response to Hamilton and Miller (2016)

    Kovach, Ryan P.; Luikart, Gordon; Lowe, Winsor H.; Boyer, Matthew C.; Muhlfeld, Clint C.

    2016-01-01

    Hamilton and Miller (2016) provide an interesting and provocative discussion of how hybridization and introgression can promote evolutionary potential in the face of climate change. They argue that hybridization—mating between individuals from genetically distinct populations—can alleviate inbreeding depression and promote adaptive introgression and evolutionary rescue. We agree that deliberate intraspecific hybridization (mating between individuals of the same species) is an underused management tool for increasing fitness in inbred populations (i.e., genetic rescue; Frankham 2015; Whiteley et al. 2015). The potential risks and benefits of assisted gene flow have been discussed in the literature, and an emerging consensus suggests that mating between populations isolated for approximately 50–100 generations can benefit fitness, often with a minor risk of outbreeding depression (Frankham et al. 2011; Aitken & Whitlock 2013; Allendorf et al. 2013).

    Full Text Available Gingival recession is a complex phenomenon that may present numerous therapeutic challenges to the clinician. The laterally positioned flap is commonly used to cover isolated, denuded roots that have adequate donor tissue laterally and vestibular depth. Various modifications in laterally sliding flap have been proposed in order to avoid the reported undesirable results on the donor teeth. Recently, use of growth factors has been proposed in combination with surgical techniques. This article highlights the use of laterally positioned pedicle flap-revised technique as a modification of laterally sliding flap technique along with autologous suspension of growth factors, platelet rich fibrin membrane (PRF for the management of localized Miller class-II gingival recession. After 6 months of follow-up, the clinical condition was stable with 80% root coverage and satisfactory gingival tissue healing at both donor and recipient site with no signs of inflammation. An excellent esthetical outcome was achieved and the patient was satisfied with case resolution.

    In order to match our ability to conceive of and construct cells with enhanced function, we must concomitantly develop facile, real-time methods for elucidating performance. With these, new designs can be tested in silico and steps in construction incrementally validated. Electrochemical monitoring offers the above advantages largely because signal transduction stems from direct electron transfer, allowing for potentially quicker and more integrated measurements. One of the most common genetic reporters, β-galactosidase, can be measured both spectrophotometrically (Miller assay) and electrochemically. However, since the relationship between the two is not well understood, the electrochemical methods have not yet garnered the attention of biologists. With the aim of demonstrating the utility of an electrochemical measurement to the synthetic biology community, we created a genetic construct that interprets and reports (with β-galactosidase) on the concentration of the bacterial quorum sensing molecule autoinducer-2. In this work, we provide a correlation between electrochemical measurements and Miller Units. We show that the electrochemical assay works with both lysed and whole cells, allowing for the prediction of one from the other, and for continuous monitoring of cell response. We further present a conceptually simple and generalized mathematical model for cell-based β-galactosidase reporter systems that could aid in building and predicting a variety of synthetic biology constructs. This first-ever in-depth comparison and analysis aims to facilitate the use of electrochemical real-time monitoring in the field of synthetic biology as well as to facilitate the creation of constructs that can more easily communicate information to electronic systems.

  1. A case study into the measurement of ship emissions from plume intercepts of the NOAA Ship Miller Freeman

    Directory of Open Access Journals (Sweden)

    C. D. Cappa

    2013-09-01

    Full Text Available Emissions factors (EFs for gas and sub-micron particle-phase species were measured in intercepted plumes as a function of vessel speed from an underway research vessel, the NOAA Ship Miller Freeman, operating a medium-speed diesel engine on low-sulfur marine gas oil. For many of the particle-phase species, EFs were determined using multiple measurement methodologies, allowing for an assessment of how well EFs from different techniques agree. The total sub-micron PM (PM1 was dominated by particulate black carbon (BC and particulate organic matter (POM, with an average POM / BC ratio of 1.3. Consideration of the POM / BC ratios observed here with literature studies suggests that laboratory and in-stack measurement methods may over-estimate primary POM EFs relative to those observed in emitted plumes. Comparison of four different methods for black carbon measurement indicates that careful attention must be paid to instrument limitations and biases when assessing EFBC. Particulate sulfate (SO42− EFs were extremely small and the particles emitted by Miller Freeman were inefficient as cloud condensation nuclei (CCN, even at high super saturations, consistent with the use of very low sulfur fuel and the overall small emitted particle sizes. All measurement methodologies consistently demonstrate that the measured EFs (fuel mass basis for PM1 mass, BC and POM decreased as the ship slowed. Particle number EFs were approximately constant across the speed change, with a shift towards smaller particles being emitted at slower speeds. Emissions factors for gas-phase CO and formaldehyde (HCHO both increased as the vessel slowed, while EFs for NOx decreased and SO2 EFs were approximately constant.

    Based on the analysis and processing on relative empirical formula and data, C-values in Larson-Miller (P) expression, P = T(C + lg t), have determined for pearlitic heat resistant steel 12Cr1Mo V and 15CrMo(20.62 and 20. 30). The simulation experiments of high temperature aging, heated from 1.5 to 873 hours, have been designed and performed for its verification. And in combination with published information and the present nearly quantitative works, it has further been verified that both the degradations of microstructures and mechanical properties show a good accuracy and practicability using the Larson-Miller parameter with the present determined C-values. Finally, the effects of carbon content on C-value are analyzed by the empirical electron theory of solids and molecules (EET).

    Anti-GQ1b antibodies were assayed by an enzyme-linked immunosorbent assay in sera from patients with non-neurological disorders (N = 20), and with various neurological disorders (N = 59), including nine cases of Miller Fisher syndrome, 16 cases of Guillain-Barré syndrome and one case of acute post-infectious ophthalmoparesis. Such antibodies were found in most cases (8 out of 9) of Miller Fisher syndrome, and at very high titres, in one case of Guillain-Barré syndrome characterised by an initial ophthalmoparesis, and in the case of isolated post-infectious ophthalmoparesis. The latter was characterised by a long-lasting occurrence of these antibodies. Anti-GQ1b antibodies are specific for an immune-mediated neuropathy of the cranial, especially oculomotor, nerves.

We believe that our patient had an MFS-AMSAN-BBE overlap syndrome. This is supported by his glycolipid antibody profile with high titres of anti-GQ1b IgG antibody and anti-GD1a IgG antibody. Anti-GQ1b antibodies are frequently found in both MFS and BBE and the anti-GD1a antibody is associated with axonal forms of GBS. Overlapping cases of MFS and BBE are well described, and because the same antibody is often found in both conditions, it is thought that they share a common autoimmune mechanism. BBE has also been previously reported in association with GBS lending support that it also lies on the same spectrum. This overlapping case of ASMAN variant of GBS, MFS, and BBE provides further support that these conditions are part of the same spectrum.

    The hepatoprotective activities of Lycium chinense Miller (LC) fruit extract and its component betaine were investigated under carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. The treatment of LC fruit extract significantly suppressed the increase of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the sera of CCl4 injured rats, and restored the decreased levels of anti-oxidant enzymes such as total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) and suppressed the expression of inflammatory mediators including inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-1 and -2. To visualize the potential activity of betaine, a component of LC fruit, betaine was substituted for LC extract in CCl4 injured rats. The biochemical profile in CCl4 injured rats co-treated with betaine matched those of LC fruit treated CCl4 injured rats. The ameliorative effects of LC extract, as well as betaine, were also confirmed by histopathological examination. Collectively, the present findings imply that LC fruit, via its component betaine, mitigate CCl4-induced hepatic injury by increasing antioxidative activity and decreasing inflammatory mediators including iNOS and COX-1/COX-2.

    The effect of intake valve closure (IVC) timing by utilizing Miller cycle and start of injection (SOI) on particulate matter (PM), particle number and nitrogen oxide (NOx) emissions was studied with a hydrotreated vegetable oil (HVO)-fueled nonroad diesel engine. HVO-fueled engine emissions, including aldehyde and polyaromatic hydrocarbon (PAH) emissions, were also compared with those emitted with fossil EN590 diesel fuel. At the engine standard settings, particle number and NOx emissions decreased at all the studied load points (50%, 75%, and 100%) when the fuel was changed from EN590 to HVO. Adjusting IVC timing enabled a substantial decrease in NOx emission and combined with SOI timing adjustment somewhat smaller decrease in both NOx and particle emissions at IVC -50 and -70 degrees CA points. The HVO fuel decreased PAH emissions mainly due to the absence of aromatics. Aldehyde emissions were lower with the HVO fuel with medium (50%) load. At higher loads (75% and 100%), aldehyde emissions were slightly higher with the HVO fuel. However, the aldehyde emission levels were quite low, so no clear conclusions on the effect of fuel can be made. Overall, the study indicates that paraffinic HVO fuels are suitable for emission reduction with valve and injection timing adjustment and thus provide possibilities for engine manufacturers to meet the strictening emission limits.

    From anthesis to mature seed formation, burrs from cross-pollinated adult Castanea sativa Miller trees were characterized and seven developmental stages defined based on macro and micromorphological traits. In order to get an insight into the involvement of epigenetic mechanisms in sexual embryogenesis and to define somatic embryogenesis induction capability, global DNA methylation and the somatic embryogenic competence were quantified. On cross-pollinated trees once fertilization takes place, at least one ovule per ovary becomes dominant, and transient DNA demethylation occurs coinciding with the start of the sexual embryogenic programme. Unfertilized ovules from the same cluster, which maintain their prior size, increase their methylation level and undergo degeneration. These results were validated using non-cross-pollinated trees and the asynchrony of flower receptivity. When testing in vitro somatic embryogenesis response of isolated dominant ovules and axes from zygotic embryos under cross-pollinated conditions, the highest competence was found for reaching seed maturity. Thus, a "developmental window" of somatic embryogenesis in chestnut has been characterized. It includes from fertilization to embryo maturity, and a transient decrease in methylation is necessary after fertilization for the development of the somatic embryogenesis response.

    UV radiations are principal causes of skin cancer and aging. Suntan creams were developed to protect epidermis and derma layers against photodegradation and photooxidation. The addition of antioxidant plant extracts (i.e. essential oil) to sunscreens is habitually performed, to increase their UV protective effects and to contrast pro-radical and cytotoxic compounds present in these solutions. According to these observations, in the present work, the alteration of chemical composition and bioactive properties of Lavandula angustifolia Miller essential oil, exposed to UV light, was investigated. UV induced a significant deterioration of lavender oil biochemical profile. Moreover, the antioxidant activity of this solution, in in vitro tests and directly on B16-F10 melanoma cells, greatly decreased after UV treatment. Our results also showed that essential oil was shielded from UV stress by propolis addition. Even after UV treatment, bee glue highly protected lavender oil secondary metabolites from degradation and also preserved their antiradical properties, both in in vitro antioxidant assays and in cell oxidative damage evaluations. This research proposed propolis as highly efficient UV protective and antiradical additive for sunscreens, cosmetics and alimentary or pharmaceutical products containing plant extracts.

    Inhibition of osteoclast differentiation and bone resorption is considered an effective therapeutic approach to the treatment of postmenopausal bone loss. To find natural compounds that may inhibit osteoclastogenesis, we screened herbal extracts on bone marrow cultures. In this study, we found that an aqueous extract of Foeniculum vulgare Miller seed (FvMs) at low concentration, which has traditionally been used as a treatment for a variety of ailments, inhibits the osteoclast differentiation and bone resorptive activity of mature osteoclasts. We further investigated the effects of FvMs on ovariectomy (OVX)-induced bone loss using microcomputed tomography, biomechanical tests and serum marker assays for bone remodeling. Oral administration of FvMs (30 mg or 100 mg/kg/day) for 6 weeks had an intermediary effect on the prevention of femoral bone mineral density (BMD), bone mineral content (BMC), and other parameters compared to OVX controls. In addition, FvMs slightly decreased bone turnover markers that were accelerated by OVX. The bone-protective effects of FvMs may be due to suppression of an OVX-induced increase in bone turnover. Collectively, our findings indicate that FvMs have potential in preventing bone loss in postmenopausal osteoporosis by reducing both osteoclast differentiation and function.

    Full Text Available Para caracterizar la resistencia a la penetración de hojas de aloe vera, variedad Barbadenses Miller, se diseñó una máquina y se establecieron los protocolos de medición para desplazamiento y fuerza necesarios para medir la resistencia a la penetración en tres puntos diferentes de las hojas. Los resultados mostraron que no existe una relación lineal entre el desplazamiento del indentador en la hoja y la fuerza de penetración. Por otro lado, se encontró que no existen diferencias en los valores de la fuerza de penetración al evaluar ésta en distintos puntos para una misma hoja. Se hallaron diferencias en los valores obtenidos entre hojas diferentes, lo que permite suponer que existe influencia de las características dimensionales de las hojas en el valor de la fuerza de penetración. Los valores máximos obtenidos para la fuerza de penetración variaron entre 22 y 27 N, para una velocidad de avance de la herramienta de 2.6 mm/s.

    In the present study, the antioxidant activity of the polysaccharides from aloe vera (Aloe barbadensis Miller) gel was evaluated, in vitro by five established methods, 1,1-diphenyl-2-picrylhydrazyl (DPPH(-)) radical scavenging, nitric oxide (NO) scavenging, hydrogen peroxide scavenging, superoxide radical (O(-2)) scavenging and reducing power assay, and in vivo against doxorubicin (DOX)-induced myocardial oxidative stress (OS) in albino wistar rats. The polysaccharides exhibited significant inhibitory activity against DPPH(-), superoxide, NO and hydrogen peroxide scavenging assay with significant reducing activity at all concentrations used. DOX-induced (7.5 mg/kg, intravenously) cardiotoxicity manifested biochemically by a significant decrease in blood and tissue glutathione (GSH) along with elevated levels of serum lactate dehydrogenase and creatine phosphokinase. In addition, cardiotoxicity was further confirmed by the significant increase in lipid peroxidation expressed as thiobarbituric acid reactive substances (TBARS), catalase (CAT) and superoxide dismutase (SOD). Administration of aloe vera polysaccharides for 14 days produced a marked protection against cardiotoxicity induced by DOX evidenced by significant reductions in serum lactate dehydrogenase, serum creatine phosphokinase, cardiac TBARS, CAT and SOD along with increased levels of blood and tissue GSH in a dose-dependent manner. The present investigation is the first to establish the antioxidant potency of the polysaccharides from aloe vera against DOX-induced myocardial OS.

  12. Interpersonal sensitivity, social inhibition, and type D personality: how and when are they associated with health? Comment on Marin and Miller (2013).

    2013-09-01

    Marin and Miller (2013) proposed interpersonal sensitivity (IS), characterized by ongoing concerns about social threats, as a new model to integrate research on interpersonal traits and health. They concluded that IS is associated with infectious and cardiovascular disease but not cancer or all-cause mortality and discussed a clear agenda for future research. However, the evidence on IS and health is mixed, and there still is much to be learned about the pathways that underpin these associations and moderators that reveal at what age and in what subgroups such associations hold. Marin and Miller noted that a toxic core of IS could be social inhibition, a related but distinct trait that refers to inhibited behavior during social interaction. On the basis of their proposition, I suggest an alternative model that points to social inhibition as an underlying trait that paves the way to IS. Social inhibition is a major determinant of chronic social stress in children and nonhuman primates. Yet, it remains uncertain whether social inhibition and its interaction with negative affectivity in Type D personality, is also related to health outcomes in adults. Many other challenges remain, but this important work of Marin and Miller highlights the need for more research on IS, social inhibition, and health. (c) 2013 APA, all rights reserved.

    Cydonia oblonga Miller (Quince) from Rosaceae family is a fruit tree cultivated in many countries mainly in Iran. This study was carried out to investigate the effect of quince juice (QJ) and quince hydroalcoholic extract (QHE) on ulcerative colitis (UC) induced by TNBS (trinitrobenzene sulfonic acid) in rats. Rats were grouped (n=6) and fasted for 36 h before colitis induction. TNBS was instilled into the colon with a hydroalcoholic carrier and then treatments were made for 5 days starting 6 h after colitis induction with different doses of QJ (200, 400, 800 mg/kg), QHE (200, 500 & 800 mg/kg) orally, QJ (400 mg/kg) and QHE (200 and 500 mg/kg) intraperitoneally. The colon tissue was removed and tissue damages were scored after macroscopic and histopathologic assessments. Albeit the examined doses of QJ and QHE were apparently effective to reduce the extent of UC lesions, only the greatest doses (500 and 800 mg/kg) resulted in significant alleviation. Weight/Length ratio as an illustrative of tissue inflammation and extravasation was also diminished with quince treatments while the results correlated with macroscopic and histopathologic evaluations. These data suggest that QJ and QHE were effective to diminish inflammation and ulcer indices in this murine model of acute colitis. Although QHE with different doses was effective in induced colitis, the dose and/or route of administration dependency was not confirmed. So quince fractions could be considered as a suitable anticolitic alternative, however further studies are needed to support this hypothesis for clinical setting.

    Background: Annona cherimola Miller (Annonaceae) is a medicinal plant frequently recommended in Mexican traditional medicine for the treatment of gastrointestinal disorders such as diarrhea and dysentery. Objective: This work was undertaken to obtain information that support the traditional use of A. cherimola, on pharmacological basis using in vitro and computational experiments. Material and Methods: Bioassay-guided fractionation of the ethanol extract of the leaves of A. cherimola afforded five phenolic compounds: caffeic acid, quercetin, kaempferol, nicotinflorin, and rutin. Results: The in vitro antiprotozoal assay showed that kaempferol was the most potent antiamoebic and antigiardial compound with IC50 values of 7.9 μg/mL for Entamoeba histolytica and 8.7 μg/mL for Giardia lamblia. Computational molecular docking study showed that kaempferol interacted in a region different than metronidazole in the enzyme pyruvate: ferredoxin oxidoreductase (PFOR). Conclusion: Considering that PFOR is a target of metronidazole; kaempferol may be a lead compound for the development of novel antiprotozoal agent. Also, these findings give support to the use of A. cherimola in the traditional medicine from México for the treatment of diarrhea and dysentery. SUMMARY Bioassay-guided fractionation of the ethanol extract of the leaves of Annona cherimola afforded five phenolic compounds: caffeic acid, quercetin, kaempferol, nicotinflorin and rutin.

    In various studies, Cydonia oblonga Miller (quince) has been reported to have many properties such as antioxidant and anti-ulcerative effects. This study has aimed to investigate the protective effects of quince aqueous extract (QAE) and quince hydroalcoholic extract (QHE) on gastric ulcer caused by indomethacin and the relevant macroscopic, histopathology, and biochemical factors in rats. Ten groups of male Wistar rats, six in each, were used in this study. These groups included: normal (distilled water), control (distilled water + indomethacin), reference (ranitidine or sucralfate + indomethacin), and test groups (QAE or QHE + indomethacin) treated with three increasing doses (200, 500, and 800 mg/kg). Extracts and drugs were given orally to rats 1 h before injecting the indomethacin (25 mg/kg, intraperitoneally). Six hours later, the abdomen of rats was exposed, its pylorus was legated, gastric acid content was extracted, and its pH and the amount of pepsin secreted were measured by Anson method. Then, histopathology indices, ulcer area, ulcer index, and myeloperoxidase (MPO) activity were measured in gastric mucus. Both extracts of quince were effective to reduce the acidity of stomach and pepsin activity. Compared to control group, the average of enzyme activity of MPO was significantly declined in all treated groups. Control group had the highest level of gastric ulcer indices including severity, area, and index while the evaluated parameters had decreased in all extract treated groups although it seems that QAE was somewhat more effective. Protective effect of QAE and QHE on gastric ulcer was done by undermining offensive factors including decreasing the secretion of gastric acid and pepsin activity and by strengthening the protective factors of gastric mucus including antioxidant capacity.

    This report provides the results of a detailed Level II analysis of scour potential at structure STOWTH00430036 on Town Highway 43 crossing the Miller Brook, Stowe, Vermont (figures 1–8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S. Department of Transportation, 1993). Results of a Level I scour investigation also are included in Appendix E of this report. A Level I investigation provides a qualitative geomorphic characterization of the study site. Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the Green Mountain section of the New England physiographic province in north central Vermont. The 5.5-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is predominantly forested. In the study area, the Miller Brook has an incised, sinuous channel with a slope of approximately 0.03 ft/ft, an average channel top width of 43 ft and an average bank height of 7 ft. The channel bed material ranges from gravel to boulder with a median grain size (D50) of 70.4 mm (0.231 ft). The geomorphic assessment at the time of the Level I and Level II site visit on July 15, 1996, indicated that the reach was stable. The Town Highway 43 crossing of the Miller Brook is a 24-ft-long, two-lane bridge consisting of one 21-foot steel-beam span (Vermont Agency of Transportation, written communication, October 13, 1995). The opening length of the structure parallel to the bridge face is 21.5 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel is skewed approximately 10 degrees to the opening and the computed opening-skew-to-roadway is also 10 degrees. The footing on the left abutment was exposed 2.5 ft and the footing on the right abutment was exposed 3.0 ft during

Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the White Mountain section of the New England physiographic province in northeastern Vermont. The 16.2-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is grass upstream and downstream of the bridge while the immediate banks have dense woody vegetation. In the study area, Millers Run has an incised, straight channel with a slope of approximately 0.01 ft/ft, an average channel top width of 50 ft and an average bank height of 6 ft. The channel bed material ranges from sand to boulder with a median grain size (D50) of 50.9 mm (0.167 ft). The geomorphic assessment at the time of the Level I and Level II site visit on August 1, 1995, indicated that the reach was laterally unstable, which is evident in the moderate to severe fluvial erosion in the upstream reach. The Town Highway 41 crossing of the Millers Run is a 30-ft-long, one-lane bridge consisting of a 28-foot steel-stringer span (Vermont Agency of Transportation, written communication, March 28, 1995). The opening length of the structure parallel to the bridge face is 22.2 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel is skewed approximately 20 degrees to the opening. The computed

    A low-power three-stage amplifier for driving large capacitive load is proposed. The feedback path formed by the active-feedback Miller capacitor leads to a high frequency complex-pole but a highQ-value, which significantly deteriorates the stability of the amplifier. The serial RC stage introduced as the second stage output load can optimize the resistorRz and the capacitorCz under fixed power and small compensation capacitorCa, which brings about a suitableQ-value of the complex-pole and the gain-bandwidth product extension of the ampli-fier. The amplifiers were designed and implemented in a standard 65 nm CMOS process with capacitive loads of 500 pF and 2 nF, respectively. The post-layout simulation results show that the amplifier driving the 500 pF capaci-tive load can achieve a gain of 113 dB, a phase margin of 50.6° and a gain-bandwidth product of 5.22 MHz while consuming 24 µW from a 1.2 V supply. For the 2 nF capacitive load, the amplifier has a gain of 102 dB, a phase margin of 52.8°, a gain-bandwidth product of 4.41 MHz and a power of 43 µW. The total compensation capacitors are equal to 1.13 pF and 1.03 pF. The better figures-of-merits are 108 750 and 205 113(MHz×pF/mW). The lay-out areas are 0.064 mm×0.026 mm and 0.063 mm×0.027 mm. Compared with the CFCC scheme, the gain-bandwidth product is extended by 1.6 times atCL=500 pF andCa=1.1 pF.

    The conflicts happened among those American expatriates in Europe is the main plot in Daisy Miller and also the main reason for Daisy' s death. The archetypal analysis on the conflicts shows that those American expatriates, who are constantly in the paradoxical and conflicting mental state between home culture and European culture ,are much more eager to assert their identity, and thus Daisy, who behaves inconsistently with the European standard, becomes inevitably their target. Persona works a lot in those American expatriates and either their too much use of it or Daisy' s too little use of it mainly account for the tragic ending of the novella.

    The analysis of Bulgarian and Turkish Rosa damascena Miller essential oils was performed by flow-modulated comprehensive two-dimensional gas chromatography using simultaneous detection of the second column effluent by flame ionization and quadrupole mass spectrometric detection. Enantioselective separations were obtained by running the samples on 2,3-di-O-ethyl-6-O-tert-butyldimethylsilyl-β-cyclodextrin column as the first column and on polyethylene glycol as the second column. The determination of enantiomeric or diastereomeric excess of some terpenoic solutes is a possible route for quality or authenticity control as well as for the elucidation of the country of origin.

    We have analyzed the chemical variety obtained by Miller-Urey-type experiments using nuclear magnetic resonance (NMR) spectroscopy and coherent anti-Stokes Raman scattering (CARS) spectroscopy, gas chromatography followed by mass spectrometry (GC/MS) and two-dimensional gas chromatography followed by mass spectrometry (GCxGC/MS). In the course of a running Miller-Urey-type experiment, a hydrophobic organic layer emerged besides the hydrophilic aqueous phase and the gaseous phase that were initially present. The gas phase mainly consisted of aromatic compounds and molecules containing C≡C or C≡N triple bonds. The hydrophilic phase contained at least a few thousands of different molecules, primarily distributed in a range of 50 and 500 Da. The hydrophobic phase is characterized by carbon-rich, oil-like compounds and their amphiphilic derivatives containing oxygen with tensioactive properties. The presence of a wide range of oxidized molecules hints to the availability of oxygen radicals. We suggest that they intervene in the formation of alkylated polyethylene glycol (PEG) in the oil/water interface. CARS spectroscopy revealed distinct vibrational molecular signatures. In particular, characteristic spectral bands for cyanide compounds were observed if the broth was prepared with electric discharges in the gaseous phase. The characteristic spectral bands were absent if discharges were released onto the water surface. NMR spectroscopy on the same set of samples independently confirmed the observation. In addition, NMR spectroscopy revealed overall high chemical variability that suggests strong non-linearities due to interdependent, sequential reaction steps.

    Full Text Available Although throughout the middle-ages Jews used to live in urban environment more than non-Jews, urbanization process in the 19th century was as critical to Jewish modern history as in other cases. Modernization, in all aspects, had a deep impact on Jewish demography, socio-economic life and self understanding. On the same time Jews were immigrating by the millions to the “new world” (mainly to the United States, a small current of Jews was heading to Palestine (Eretz Israel if to use their specific term. As opposed to a common understanding of Zionism, the future city and the neo-urbanization of the Jews – and not only the new villages (Moshavot, Kibbutzim, Moshavim – was a main Zionist goal. This article describes one of the first comprehensive observations of these issues, as seen from the eyes of Louis Miller, himself a Jewish immigrant that settled in the outmost city of the modern world: New York. In 1911 he paid a visit to the one-year-old Tel Aviv, and managed to see in this new modest garden-city the cradle of the Zionist revolution. Not less important: Miller understood as early as 1911, the crucial role Jewish settlements in Palestine would have in the crystallization of modern Jewish peoplehood. Tel Aviv took major part in this development. It still does.

    Full Text Available Introduction: Plants are usually exposed to different environmental stresses which limit their growth and productivity as well as cause considerable loss of worldwide agricultural production. One of the most important factors affecting plant and production of secondary metabolites is the salt stress. Salinity of soil or water is one of major stress, obstacles to increase production in plant growing areas throughout the world and especially in arid and semi-arid regions it can severely limit plant production. Iran is among the world's arid and semi-arid land, and faces water resources shortage and saline lands. According to the concept of sustainable development and role of Agriculture, using saline water and soil resources seems mandatory. Recently, medicinal and aromatic plants have received much attention in several fields such as agroalimentary, perfumes, pharmaceutical industries and natural cosmetic products. Although, secondary metabolites in the medicinal and aromatic plants were fundamentally produced by genetic processing, but, their biosynthesis are strongly influenced by environmental factors. It means that biotic and abiotic environmental factors affect growth parameter, essential oil yield and constituents. Abiotic environmental stresses, especially salinity and drought have the most effect on medicinal plant. Medicinal plants cultivation is one of ways to exploit these resources. Essential oils help to easier adapt to the environmental stress conditions. Also, essential oils are not constantly in the quantitative and qualitative terms. They are changing continuously, due to the requirements of the environment, and to individual survival. The different results were dedicated from the effect of salinity stress on the quantitative and qualitative parameters. Lavender (Lavandula angustifulia Miller is a perennial woody medicinal plant that cultivated for its an essential oil in leafs and flowers. Major parts of Lavender produces

    Miller Range 07273 is a chondritic melt breccia that contains clasts of equilibrated ordinary chondrite set in a fine-grained (pressure, a sudden pressure drop, and a slower drop in temperature. Olivine and orthopyroxene in chondrule clasts were the least melted and the most deformed, whereas matrix and troilite melted completely and crystallized to nearly strain-free minerals. Coarse metal was largely but incompletely liquefied, and matrix silicates formed by the breakdown during melting of albitic feldspar and some olivine to form pyroxene at high pressure (>3 GPa, possibly to 15-19 GPa) and temperature (>1350 °C, possibly to ≥2000 °C). The higher pressures and temperatures would have involved back-reaction of high-pressure polymorphs to pyroxene and olivine upon cooling. Silicates outside of melt matrix have compositions that were relatively unchanged owing to brief heating duration.

    When studies examine true effects, they generate right-skewed p-curves, distributions of statistically significant results with more low (.01 s) than high (.04 s) p values. What else can cause a right-skewed p-curve? First, we consider the possibility that researchers report only the smallest significant p value (as conjectured by Ulrich & Miller, 2015), concluding that it is a very uncommon problem. We then consider more common problems, including (a) p-curvers selecting the wrong p values, (b) fake data, (c) honest errors, and (d) ambitiously p-hacked (beyond p < .05) results. We evaluate the impact of these common problems on the validity of p-curve analysis, and provide practical solutions that substantially increase its robustness.

    Full Text Available The solar (S and lunar (L variations of geomagnetic fields at the horizontal (H, declination (D, and the downward vertical component data (Z are modeled by the Chap man-Miller method with four order harmonics. In this paper, we compare S and L variations of the geomagnetic total intensity field using a consistent method with 3-component data for seasonal variations (summer, winter, and equinox for three distinct phases during the years 1988 - 2007. The results show that consistency in the S and L variations for geomagnetic total intensity indicates normal stations and discrepancies are occurred due to data quality. In application, consistent results also prove that the function of the magnetometers at TW was normal and that large anomalies were certainly in existence during the Chia-Yi earthquake.

    Models of three representative higher Miller index interfaces, Si(310):SiO{sub 2}, Si(410):SiO{sub 2}, and Si(331):SiO{sub 2}, have been built by an ab-initio molecular dynamics method. We show that each interface can be made as a fully bonded network without any defects and has a reasonable electronic structure for use in fin field effect transistors or gate-all-around nanowire devices. The differences in numbers of oxygen bridges are attributed to the intermediate sub-oxide components and the atomic step structure. The interface bonding schemes to passivate different densities of dangling bonds on different facets are also analyzed.

    We present experimental evidence to show that acetylcholine (ACh) causes decrease in shoot formation in leaf explants of tomato (Lycopersicon esculentum Miller var Pusa Ruby) when cultured on shoot regeneration medium. The optimum response was obtained at 10(-4) M ACh-enriched medium. ACh also causes decrease in percentage of cultures forming callus and reduces the callus mass. Inhibitors of enzymatic hydrolysis of ACh, neostigmine and physostigmine, also suppresses callogenesis and caulogenesis. On the other hand, the breakdown products of Ach, choline and acetate, do not alter the morphogenic response induced on the shoot regeneration medium. Neostigmine showed optimal reduction in shoot formation at 10(-5) M. The explants cultured on neostigmine augmented medium showed decline in the activity of ACh hydrolyzing enzyme acetylcholinesterase. ACh and neostigmine added together showed marked reduction in callus mass. These results strongly support the role of ACh as a natural regulator of morphogenesis in tomato plants.

    Submicroscopic duplications in the Miller-Dieker critical region have been recently described as new genomic disorders. To date, only a few cases have been reported with overlapping 17p13.3 duplications in this region. Also, small deletions that affect chromosome region 10p14→pter are rarely described in the literature. In this study, we describe, to our knowledge for the first time, a 5-year-old female patient with intellectual disability who has an unbalanced 10;17 translocation inherited from the father. The girl was diagnosed by subtelomeric FISH and array-CGH, showing a 4.43-Mb heterozygous deletion on chromosome 10p that involved 14 genes and a 3.22-Mb single-copy gain on chromosome 17p, which includes the critical region of the Miller-Dieker syndrome and 61 genes. The patient's karyotype was established as 46,XX.arr 10p15.3p15.1(138,206–4,574,436)x1,17p13.3(87,009–3,312,600)x3. Because our patient exhibits a combination of 2 imbalances, she has phenotypic features of both chromosome abnormalities, which have been reported separately. Interestingly, the majority of patients who carry the deletion 10p have visual and auditory deficiencies that are attributed to loss of the GATA3 gene. However, our patient also presents severe hearing and visual problems even though GATA3 is present, suggesting the involvement of different genes that affect the development of the visual and auditory systems.

    Tissue trauma caused by traumatic toothbrushing is considered to be a dominating causative factor for the development of recessions, particularly in young individuals. Recessions resulting from improver toothbrushing techniques are often found at sites with clinically healthy gingiva and where the exposed root has a wedgeshaped defect, the surface of which is clean, smooth and polished. Free connective tissue graft combined with a double papilla flap surgery and semi-lunar coronally repositioned flap methods leads to a significantly favorable clinical improvement of treatment of deep Class II Miller gingival recession defects

    A public hearing was held at the request of the Quebec Minister of the Environment to examine the environmental and socio-economic impacts of a proposed wind farm project at Mount Copper and Mount Miller in Murdochville, Quebec. The first phase of the project involves the construction of a wind turbine array with a capacity of 9 megawatts (MW), followed by a second phase expansion to 45 MW for 2004. The final wind turbine array includes 36 turbines for a total capacity of 54 megawatts (MW). The region is well suited for wind energy projects. Energie Eolienne du Mont Miller Inc. and Northland Power Inc. intend to develop the wind farm at a cost of approximately $90 million. Hydro Quebec has agreed to purchase the electricity. The various impacts of the proposed project were examined, both from an environmental and a socio-economic perspective. The Commission determined that the wind farm would not have significant impacts and that the project is desirable. Certain conditions must be met to ensure sustainable development. In terms of ecology, the Commission would like to have a complete inventory of the bird species and a description of the corridors of migration. It would also like to see the promoters show leadership in minimizing the impacts of the project on the ecotourism activities offered in the area. 17 refs., 1 tab., 1 fig., 2 appendices.

    Effectiveness in visualization of the vocal cord during orotracheal intubation with McCoy (McC) compared with Macintosh (Min) and Miller (Mil) blades were investigated. After an institutional review board approval, 117 patients for elective surgery under general anesthesia requiring tracheal intubation were investigated. Five board certified anesthesiologists tried to visualize the vocal cord of a patient three times with the three different types of laryngoscope. Total of 351 intubation attempts were studied. The view obtained at laryngoscopy with each of the three blades was recorded as follows. Grade 1. If most of the glottis is visible. Grade 2. If only the posterior extremity of the glottis is visible. Grade 3. If no part of the glottis can be seen. Grade 4. If not even the epiglottis can be exposed. Eight-two Grade 1 views were obtained with McC, 72 with Mil and 47 with Min, respectively. Thirty-three Grade 2 views were obtained with McC, 36 with Min and 24 with Mil. Two Grade 3 views with McC, 34 with Min and 14 with Mil were obtained. Seven Grade 4 views were obtained with Mil. The grades of laryngeal visualization with McC were significantly lower than those with Min and Mil.

  5. Prebiotic Synthesis of Methionine and Other Sulfur-Containing Organic Compounds on the Primitive Earth: A Contemporary Reassessment Based on an Unpublished 1958 Stanley Miller Experiment

    Original extracts from an unpublished 1958 experiment conducted by the late Stanley L. Miller were recently found and analyzed using modern state-of-the-art analytical methods. The extracts were produced by the action of an electric discharge on a mixture of methane (CH4), hydrogen sulfide (H2S), ammonia (NH3), and carbon dioxide (CO2). Racemic methionine was farmed in significant yields, together with other sulfur-bearing organic compounds. The formation of methionine and other compounds from a model prebiotic atmosphere that contained H2S suggests that this type of synthesis is robust under reducing conditions, which may have existed either in the global primitive atmosphere or in localized volcanic environments on the early Earth. The presence of a wide array of sulfur-containing organic compounds produced by the decomposition of methionine and cysteine indicates that in addition to abiotic synthetic processes, degradation of organic compounds on the primordial Earth could have been important in diversifying the inventory of molecules of biochemical significance not readily formed from other abiotic reactions, or derived from extraterrestrial delivery.

  6. The Ar-Ar age and petrology of Miller Range 05029: Evidence for a large impact in the very early solar system

    Miller Range (MIL) 05029 is a slowly cooled melt rock with metal/sulfide depletion and an Ar-Ar age of 4517 ± 11 Ma. Oxygen isotopes and mineral composition indicate that it is an L chondrite impact melt, and a well-equilibrated igneous rock texture with a lack of clasts favors a melt pool over a melt dike as its probable depositional setting. A metallographic cooling rate of approximately 14 °C Ma-1 indicates that the impact occurred at least approximately 20 Ma before the Ar-Ar closure age of 4517 Ma, possibly even shortly after accretion of its parent body. A metal grain with a Widmanstätten-like pattern further substantiates slow cooling. The formation age of MIL 05029 is at least as old as the Ar-Ar age of unshocked L and H chondrites, indicating that endogenous metamorphism on the parent asteroid was still ongoing at the time of impact. Its metallographic cooling rate of approximately 14 °C Ma-1 is similar to that typical for L6 chondrites, suggesting a collisional event on the L chondrite asteroid that produced impact melt at a minimum depth of 5-12 km. The inferred minimum crater diameter of 25-60 km may have shattered the 100-200 km diameter L chondrite asteroid. Therefore, MIL 05029 could record the timing and petrogenetic setting for the observed lack of correlation of cooling rates with metamorphic grades in many L chondrites.

    In the late 1930s, the Institute of Human Relations of Yale University developed a research program on conflict and anxiety as an outcome of Clark Hull's informal seminar on the integration of Freud's and Pavlov's theories. The program was launched at the 1937 Annual Meeting of the APA in a session chaired by Clark L. Hull, and the experiments continued through 1941, when the United States entered the Second World War. In an effort to apply the findings from animal experiments to the war situation, John Dollard and Neal E. Miller decided to study soldiers' fear reactions in combat. As a first step, they arranged interviews with a few veterans of the Abraham Lincoln Brigade. Taking these interviews as a point of departure, Dollard devised a questionnaire to which 300 former Lincoln brigaders responded. The present paper analyzes the main outcomes of the questionnaire, together with the war experiences reported in the interview transcripts. Our purpose was to evaluate a project which was initially investigated by the FBI because of the communists among the Lincoln ranks, but eventually supported by the American Army, and which exerted great influence on the military psychology of the time.

    The strigeid digenean species Australapatemon burti (Miller, 1923) (Trematoda: Digenea: Strigeidae) was originally described from North America, but recorded in the Neotropical region (Drago et al. 2007; Hernández-Mena et al. 2014; Blasco-Costa et al. 2016) and in Central Europe (Faltýnková et al. 2007). In Europe, this species is rare, and there is not much information about its range (Faltýnková et al. 2007; Soldánová et al. 2012). Australapatemon burti has a complex life cycle with three larval stages, two of which (sporocyst and cercaria) use several species of freshwater snails, and the third stage (metacercaria) use non-specific host hirudineans (Dubois 1968; Davies & Ostrowski de Núñez 2012; Blasco-Costa et al. 2016). Adult flukes are parasitic in the intenstines of various waterfowl species, such as ducks and swans (Drago et al. 2007; Hernández-Mena et al. 2014). Currently, the molecular data on this parasite species includes only nucleotide sequences of four adult specimens from Mexico (Hernández-Mena et al. 2014). Their hosts were Mexican duck, Anas diazi Ridgway, American Wigeon, Anas americana Gmelin, Cinnamon Teal, Anas cyanoptera Vieillot, and Ruddy Duck, Oxyura jamaicensis (Gmelin) (Anserformes: Anatidae).

    Full Text Available Aim: The aim of this study is to see the different functional gradings of Eustachian tube ventilatory function as assessed by Bortnick-Miller (B-M apparatus in chronically diseased middle ears (dry cases planned to undergo tympanoplasty and to correlate the results with the past experiences. Materials and Methods: This study consisted of 29 cases of chronic suppurative otitis media, inactive stage having central perforation. Tubal function was evaluated by B-M apparatus based on ability of tube assimilating the applied positive and negative pressure. Tubal opening pressure was noted after applying positive pressure while residual intratympanic pressure after 10 swallows was recorded after applying negative pressure. Results: This study revealed that results of tubal manometry in diseased ears cover a wide spectrum of normal function to partial/non-function. 51.72% of cases were able to equalize applied negative pressure, 41.39% partially equalizing, while 6.89% of cases were completely unable to equalize applied negative pressure. Conclusion: Our results of aspiration method with the help of BM apparatus explicitly suggest that tubal function in chronically diseased ears deviates from that of normal ears. It perpetually reflects that varied results of middle ear reconstructive surgeries could be anticipated in accordance with different tubal function gradings.

    The Miller-Dieker syndrome (MDS), composed of characteristic facial abnormalities and a severe neuronal migration disorder affecting the cerebral cortex, is caused by visible or submicroscopic deletions of chromosome band 17p13. Twelve anonymous DNA markers were tested against a panel of somatic cell hybrids containing 17p deletions from seven MDS patients. All patients, including three with normal karyotypes, are deleted for a variable set of 5-12 markers. Two highly polymorphic VNTR (variable number of tandem repeats) probes, YNZ22 and YNH37, are codeleted in all patients tested and make molecular diagnosis for this disorder feasible. By pulsed-field gel electrophoresis, YNZ22 and YNH37 were shown to be within 30 kilobases (kb) of each other. Cosmid clones containing both VNTR sequences were identified, and restriction mapping showed them to be <15 kb apart. Three overlapping cosmids spanning >100 kb were completely deleted in all patients, providing a minimum estimate of the size of the MDS critical region. A hypomethylated island and evolutionarily conserved sequences were identified within this 100-kb region, indications of the presence of one or more expressed sequences potentially involved in the pathophysiology of this disorder. The conserved sequences were mapped to mouse chromosome 11 by using mouse-rat somatic cell hybrids, extending the remarkable homology between human chromosome 17 and mouse chromosome 11 by 30 centimorgans, into the 17p telomere region.

    Full Text Available Abstract Background Bickerstaff’s brainstem encephalitis (BBE, together with Miller Fisher syndrome (MFS and Guillain-Barré syndrome (GBS were considered to form a continuous clinical spectrum. An anti-GQ1b antibody syndrome has been proposed to underlie the common pathophysiology for the three disorders; however, other studies have found a positive anti-GM1 instead of anti-GQ1b antibody. Case presentation Here we report a 20-year-old male patient with overlapping BBE, MFS and GBS. The patient had a positive family history of bronchial asthma and had suffered from the condition for over 15 years. He developed BBE symptoms nine days after an asthma exacerbation. During the course of illness, he had significantly elevated IgE levels in both serum and cerebrospinal fluid. Serologic analysis of antibodies against ganglioside complexes (anti-GDIa, anti-GDIb, anti-GM1, anti-GM2, anti-GM3, anti-GQIb and anti-GTIb antibodies showed negative results. Conclusions Since asthma has recently been related to autoimmune disease, our case supports an autoimmune mechanism underlying the clinical spectrum composed of BBE, MFS and GBS. However, contrary to a proposed anti-GQ1b antibody syndrome, we would suggest that pathogenesis of this clinical spectrum is not limited to anti-ganglioside antibodies.

  12. Bioassay-Guided Chemical Study of the Anti-Inflammatory Effect of Senna villosa (Miller H.S. Irwin & Barneby (Leguminosae in TPA-Induced Ear Edema

    Full Text Available Senna villosa (Miller is a plant that grows in México. In traditional Mexican medicine, it is used topically to treat skin infections, pustules and eruptions and to heal wounds by scar formation. However, studies of its potential anti-inflammatory effects have not been performed. The aim of the present study was to determine the anti-inflammatory effect of extracts from the leaves of Senna villosa and to perform a bioassay-guided chemical study of the extract with major activity in a model of ear edema induced by 12-O-tetradecanoylphorbol 13-acetate (TPA. The results reveal that the chloroform extract from Senna villosa leaves has anti-inflammatory and anti-proliferative properties. Nine fractions were obtained from the bioassay-guided chemical study, including a white precipitate from fractions 2 and 3. Although none of the nine fractions presented anti-inflammatory activity, the white precipitate exhibited pharmacological activity. It was chemically characterized using mass spectrometry and infrared and nuclear magnetic resonance spectroscopy, resulting in a mixture of three aliphatic esters, which were identified as the principal constituents: hexyl tetradecanoate (C20H40O2, heptyl tetradecanoate (C21H42O2 and octyl tetradecanoate (C22H44O2. This research provides, for the first time, evidence of the anti-inflammatory and anti-proliferative properties of compounds isolated from Senna villosa.

    Background: The aim of this study was to compare the clinical efficacy of coronally advanced flap (CAF) alone and in combination with autologous platelet rich fibrin membrane (PRF) in Miller's class I and II gingival recessions. Materials and Method: Thirty isolated Miller class I or II sites in 26 subjects were randomly divided into test (15 sites- CAF+PRF) and control (15 sites- CAF alone). Parameters probing pocket depth (PPD), Recession depth (RD), Clinical attachment loss (CAL), Keratinised tissue width (KTW) and Gingival tissue thickness (GTH) were evaluated at baseline, 3 months and 6 months postoperatively. Data was subjected to statistical analysis. P< 0.05 was considered statistically significant. Results: Mean percentage root coverage was 91.00±19.98% and 86.60±23.83% for test and control group respectively. Difference between the groups in all parameters at baseline, 3 months and 6 months was non significant. Complete root coverage was obtained in 12 (80%) and 11 (73.3%) subjects in test and control group respectively. The difference was found to be non-significant. Both groups showed significant differences in all parameters at 3 and 6 months respectively except difference in gingival tissue thickness which was non-significant in control group at 3 months. Conclusion: Combination of PRF to CAF procedure did not provide any added advantage in term of recession coverage in Miller class I and II recessions. Long term trials with more sample size are needed to validate these findings. PMID:26097347

    Sapota fruits are highly perishable due to their climacteric nature. The rapid softening of fruits is primarily due to high activity of many oxidative enzymes and liberation of ethylene. Harvest maturity plays a crucial role in deciding the marketability of climacteric fruits in general. Attempt has been made to evaluate the response of ethylene absorbent on variable maturity groups of harvested Sapota cv. Kallipatti with the objective to delay the ripening during transit and extend its marketability during storage at ambient condition (27-32 °C & 65-75% R.H.). Harvested fruits having three different degree of ripeness (as maturity indices viz. mature, half-ripe and ripe) were packed with or without ethylene absorbent sachets (Bioconservación, France) in 10 kg CFB boxes and transported from Dahnu to Delhi covering a distant of approximately 2500 KM by truck on road along with conventional packaging as control. The fruits were evaluated immediately on arrival at Delhi and subsequently during storage for various physical, physiological, biochemical and decay parameters. Mature fruits with ethylene absorbent exhibited maximum delay in ripening, low ethylene liberation, weight loss and high fruit firmness. The response of ethylene absorbent to extend the marketability of ripe fruit was not significant.

  16. Hydrology of the North Fork of the Right Fork of Miller Creek, Carbon County, Utah, before, during, and after underground coal mining

    From 1988-92 the U.S. Geological Survey, in cooperation with the Utah Division of Oil, Gas, and Mining, studied the effects of underground coal mining and the resulting subsidence on the hydrologic system near the North Fork of the Right Fork of Miller Creek, Carbon County, Utah. The subsidence caused open fractures at land surface, debris slides, and rockfalls in the canyon above the mined area. Land surface subsided and moved several feet horizontally. The perennial stream and a tributary upstream from the mined area were diverted below the ground by surface fractures where the overburden thickness above the Wattis coal seam is 300 to 500 feet. The reach downstream was dry but flow resumed where the channel traversed the Star Point Sandstone, which forms the aquifer below the coal seams where ground-water discharge provides new base flow. Concentrations of dissolved constituents in the stream water sampled just downstream from the mined area increased from about 300 mg/L (milligrams per liter) to more than 1,500 mg/L, and the water changed from primarily a magnesium calcium bicarbonate to primarily a magnesium sulfate type. Monitored water levels in two wells completed in the perched aquifer(s) above the mine indicate that fractures from subsidence- related deformation drained the perched aquifer in the Blackhawk Formation. The deformation also could have contributed to the decrease in discharge of three springs above the mined area, but discharge from other springs in the area did not change ubstantially; thus, the relation between subsidence and spring discharge, if any, is not clear. No significant changes in the chemical character of water discharging from springs were detected, but the dissolved-solids concentration in water collected from a perched sandstone aquifer overlying the mined coal seams increased during mining activity.

  17. Clear Evidence of Carcinogenic Activity by a Whole-Leaf Extract of Aloe barbadensis Miller (Aloe vera) in F344/N Rats

    Aloe barbadensis Miller (Aloe vera) is an herbal remedy promoted to treat a variety of illnesses; however, only limited data are available on the safety of this dietary supplement. Drinking water exposure of F344/N rats and B6C3F1 mice to an Aloe vera whole-leaf extract (1, 2, and 3%) for 13 weeks resulted in goblet cell hyperplasia of the large intestine in both species. Based upon this observation, 2-year drinking water studies were conducted to assess the carcinogenic potential of an Aloe vera whole-leaf extract when administered to F344/N rats (48 per sex per group) at 0.5, 1, and 1.5%, and B6C3F1 mice (48 per sex per group) at 1, 2, and 3%. Compared with controls, survival was decreased in the 1.5% dose group of female rats. Treatment-related neoplasms and nonneoplastic lesions in both species were confined primarily to the large intestine. Incidences of adenomas and/or carcinomas of the ileo-cecal and cecal-colic junction, cecum, and ascending and transverse colon were significantly higher than controls in male and female rats in the 1 and 1.5% dose groups. There were no neoplasms of the large intestine in mice or in the 0 or 0.5% dose groups of rats. Increased incidences of mucosa hyperplasia of the large intestine were observed in F344/N rats, and increased incidences of goblet cell hyperplasia of the large intestine occurred in B6C3F1 mice. These results indicate that Aloe vera whole-leaf extract is an intestinal irritant in F344/N rats and B6C3F1 mice and a carcinogen of the large intestine in F344/N rats. PMID:22968693

  19. Likelihood of obtaining Structured Interview of Reported Symptoms (SIRS) and SIRS-2 elevations among forensic psychiatric inpatients with screening elevations on the Miller Forensic Assessment of Symptoms Test.

    The Miller Forensic Assessment of Symptoms Test (M-FAST) was designed as a screening measure for feigned psychiatric symptoms. When M-FAST Total Scores are elevated (raw score ≥6), the test manual recommends follow-up with a more comprehensive measure of feigning, such as the widely used and researched Structured Interview of Reported Symptoms (SIRS) or the revised version of the test (SIRS-2). The purpose of the current study was to evaluate how often M-FAST screening elevations are associated with subsequent elevations on the SIRS or SIRS-2. The sample included archival data from 100 forensic psychiatric inpatients who obtained M-FAST Total Score elevations ≥6 during screening and were subsequently administered the SIRS (that was also rescored using SIRS-2 criteria). Among examinees who elevated the M-FAST over the recommended cutoff, 66.0% met standard SIRS feigning criteria, 42% met SIRS-2 criteria for feigning, and 81.0% obtained at least 1 SIRS/SIRS-2 elevation in the Probable Feigning range or higher. These results are consistent with the M-FAST manual guidelines, which support the use of the ≥6 M-FAST cutoff score to screen for potential feigning (but not as an independent marker of feigning). A higher M-FAST cutoff score of ≥16 was associated with subsequently meeting full SIRS criteria for feigning in 100.0% of protocols. Because the SIRS criteria were designed to have very low false positive rates, these findings indicate that more confident assertions about feigning can be made when elevations reach this level on the MFAST.

    KEY MESSAGE : The study determined the tolerance of Aloe vera to high temperature, focusing on the expression of hsp70 , hsp100 and ubiquitin genes. These were highly expressed in plants acclimated at 35 °C prior to a heat shock of 45 °C. Aloe barbadensis Miller (Aloe vera), a CAM plant, was introduced into Chile in the semiarid IV and III Regions, which has summer diurnal temperature fluctuations of 25 to 40 °C and annual precipitation of 40 mm (dry years) to 170 mm (rainy years). The aim of this study was to investigate how Aloe vera responds to water and heat stress, focusing on the expression of heat shock genes (hsp70, hsp100) and ubiquitin, which not studied before in Aloe vera. The LT(50) of Aloe vera was determined as 53.2 °C. To study gene expression by semi-quantitative RT-PCR, primers were designed against conserved regions of these genes. Sequencing the cDNA fragments for hsp70 and ubiquitin showed a high identity, over 95 %, with the genes from cereals. The protein sequence of hsp70 deduced from the sequence of the cDNA encloses partial domains for binding ATP and the substrate. The protein sequence of ubiquitin deduced from the cDNA encloses a domain for interaction with the enzymes E2, UCH and CUE. The expression increased with temperature and water deficit. Hsp70 expression at 40-45 °C increased 50 % over the controls, while the expression increased by 150 % over the controls under a water deficit of 50 % FC. The expression of all three genes was also studied under 2 h of acclimation at 35 or 40 °C prior to a heat shock at 45 °C. Under these conditions, the plants showed greater expression of all genes than when they were subjected to direct heat stress.

    Highlights: Black-Right-Pointing-Pointer Quince peel polyphenols inhibit LPS-induced secretion of TNF-{alpha} and IL-8. Black-Right-Pointing-Pointer Quince peel polyphenols augment LPS-induced secretion of IL-10 and IL-6. Black-Right-Pointing-Pointer Quince peel polyphenols-mediated inhibition of LPS-induced secretion of TNF-{alpha} is partially mediated by IL-6. Black-Right-Pointing-Pointer The anti-inflammatory effects of quince polyphenols pass through NF-{kappa}B, p38MAPK and Akt inhibition. -- Abstract: Chronic inflammation is a hallmark of several pathologies, such as rheumatoid arthritis, gastritis, inflammatory bowel disease, atherosclerosis and cancer. A wide range of anti-inflammatory chemicals have been used to treat such diseases while presenting high toxicity and numerous side effects. Here, we report the anti-inflammatory effect of a non-toxic, cost-effective natural agent, polyphenolic extract from the Tunisian quince Cydonia oblonga Miller. Lipopolysaccharide (LPS) treatment of human THP-1-derived macrophages induced the secretion of high levels of the pro-inflammatory cytokine TNF-{alpha} and the chemokine IL-8, which was inhibited by quince peel polyphenolic extract in a dose-dependent manner. Concomitantly, quince polyphenols enhanced the level of the anti-inflammatory cytokine IL-10 secreted by LPS-treated macrophages. We further demonstrated that the unexpected increase in IL-6 secretion that occurred when quince polyphenols were associated with LPS treatment was partially responsible for the polyphenols-mediated inhibition of TNF-{alpha} secretion. Biochemical analysis showed that quince polyphenols extract inhibited the LPS-mediated activation of three major cellular pro-inflammatory effectors, nuclear factor-kappa B (NF-{kappa}B), p38MAPK and Akt. Overall, our data indicate that quince peel polyphenolic extract induces a potent anti-inflammatory effect that may prove useful for the treatment of inflammatory diseases and that a quince

    Dried male inflorescences of breadfruit ( Artocarpus altilis , Moraceae) are burned in communities throughout Oceania to repel flying insects, including mosquitoes. This study was conducted to identify chemicals responsible for mosquito deterrence. Various crude extracts were evaluated, and the most active, the hydrodistillate, was used for bioassay-guided fractionation. The hydrodistillate and all fractions displayed significant deterrent activity. Exploratory GC-MS analysis revealed more than 100 distinctive peaks, and more than 30 compounds were putatively identified, including a mixture of terpenes, aldehydes, fatty acids, and aromatics. A systematic bioassay-directed study using adult Aedes aegypti females identified capric, undecanoic, and lauric acid as primary deterrent constituents. A synthetic mixture of fatty acids present in the most active fraction and individual fatty acids were all significantly more active than N,N-diethyl-m-toluamide (DEET). These results provide support for this traditional practice and indicate the potential of male breadfruit flowers and fatty acids as mosquito repellents.

    This work aimed to evaluate the influence of Gamma radiation of Cobalt-60, in the avocado moth Stenoma catenifer Walsingham, 1912 (Lepidoptera: Elachistidae) and its effects on the quality of the fruit Persea americana (Miller) (Lauraceae). For this research, insects were irradiated in ali phases of their life cycle with doses varying from O to 600 Gy and they were maintained at the temperature of 25 +- 2 deg C, humidity of 70 +- 10% and photo phase of 14 h. The species was raised on natural diet, avocado seeds. The cultivar fruits Geada were irradiated with doses that varied from 0 to 150 Gy, maintained for 15 days at room temperature (20 a 35 deg C and humidity of 70 - 80 %) and 30 days at a temperature of 10 deg C, humidity of 40 - 60 %. The chemical-physics and sensorial analyses were carried out. According to the obtained results, it was verified that the lethal dose of gamma radiation to S. catenifer eggs, was of 75 Gy; for caterpillars and pupas was of 300 Gy. The sterile-dose for upcoming adults from irradiated S. catenifer eggs was of 25 Gy; for upcoming adults from irradiated caterpillars, it was of 100 Gy; for adults coming from irradiated pupas was of 150 Gy and for irradiated adults was of 200 Gy. The irradiation in the avocado fruit, maintained at room temperature for 7 days of storage, caused change in the coloration of the fruit (dark spots and yellowish coloration) and more firmness. The sensorial characteristics were kept and the irradiated fruit was the chosen one as favorite for tasting. The irradiated fruits that were kept at 10 deg C, obtained an increase in the storage period, without changing their chemical physics characteristics. The coloration of the fruits was kept, more firmness and a subtle acidity taste increase, being effective in the conservation of the fruits and in the maintenance of their sensorial characteristics. The use of the gamma radiation as treatment quarantine of S. catenifer it was efficient, should be treated them with

Materials and Method: Thirty isolated Miller class I or II sites in 26 subjects were randomly divided into test (15 sites- CAF+PRF and control (15 sites- CAF alone. Parameters probing pocket depth (PPD, Recession depth (RD, Clinical attachment loss (CAL, Keratinised tissue width (KTW and Gingival tissue thickness (GTH were evaluated at baseline, 3 months and 6 months postoperatively. Data was subjected to statistical analysis. P< 0.05 was considered statistically significant. Results: Mean percentage root coverage was 91.00±19.98% and 86.60±23.83% for test and control group respectively. Difference between the groups in all parameters at baseline, 3 months and 6 months was non significant. Complete root coverage was obtained in 12 (80% and 11 (73.3% subjects in test and control group respectively. The difference was found to be non-significant. Both groups showed significant differences in all parameters at 3 and 6 months respectively except difference in gingival tissue thickness which was non-significant in control group at 3 months. Conclusion: Combination of PRF to CAF procedure did not provide any added advantage in term of recession coverage in Miller class I and II recessions. Long term trials with more sample size are needed to validate these findings.

    In this study, we present application of an artificial intelligence (AI) technique model called dynamic evolving neural-fuzzy inference system (DENFIS) based on an evolving clustering method (ECM), for modelling dissolved oxygen concentration in a river. To demonstrate the forecasting capability of DENFIS, a one year period from 1 January 2009 to 30 December 2009, of hourly experimental water quality data collected by the United States Geological Survey (USGS Station No: 420853121505500) station at Klamath River at Miller Island Boat Ramp, OR, USA, were used for model development. Two DENFIS-based models are presented and compared. The two DENFIS systems are: (1) offline-based system named DENFIS-OF, and (2) online-based system, named DENFIS-ON. The input variables used for the two models are water pH, temperature, specific conductance, and sensor depth. The performances of the models are evaluated using root mean square errors (RMSE), mean absolute error (MAE), Willmott index of agreement (d) and correlation coefficient (CC) statistics. The lowest root mean square error and highest correlation coefficient values were obtained with the DENFIS-ON method. The results obtained with DENFIS models are compared with linear (multiple linear regression, MLR) and nonlinear (multi-layer perceptron neural networks, MLPNN) methods. This study demonstrates that DENFIS-ON investigated herein outperforms all the proposed techniques for DO modelling.

  13. Quadratic Sagnac effect — the influence of the gravitational potential of the Coriolis force on the phase difference between the arms of a rotating Michelson interferometer (an explanation of D C Miller's experimental results, 1921 - 1926)

    It is shown that when an equal-arm Michelson interferometer is involved in rotation (for example, Earth's rotation around its axis or around the Sun) and its arms are oriented differently with respect to the plane of rotation, a phase difference arises between the light rays that pass through different arms. This phase difference is due to the fact that the arms experience variously the Newtonian (nonrelativistic) scalar gravitational potential of the Coriolis forces. It is shown that the phase difference is proportional to the length of the interferometer arm, the square of the angular velocity of the rotation, and the square of the distance from the center of rotation — hence, the proposal to call this phenomenon the quadratic Sagnac effect. In the present paper, we consider, as an illustrative example, the results of the once well-known experiments of D C Miller, who claimed to observe the translational motion of Earth relative to the hypothetical ‘luminiferous ether’. It is shown that this claim can actually be explained by the fact that, because of the orbital revolution of Earth, the time dilations in the orthogonal arms of the Michelson interferometer are influenced differently by the scalar gravitational potential of the Coriolis forces.

    Miller Range (MIL) 05035 and LaPaz Icefield (LAP) 02224 are unbrecciated lunar basalt meteorites. In this report, we studied their petrography and mineralogy and made in situ uranogenic Pb/Pb dating of Zr-rich minerals. Petrography and mineralogy of these two lunar meteorites are consistent with previous investigations. The zirconolite Pb/Pb age of MIL 05035 is 3851±8 Ma (2σ), in excellent agreement with previous reports. This age suggests that MIL 05035 could be paired with Asuka 881757, a low-Ti mare basalt meteorite. The magmatic event related to MIL 05035 was probably due to the late heavy impact bom- bardment on the moon around 3.9 Ga. One baddeleyite grain in LAP 02224 shows a large variation of Pb/Pb age, from 3109±29 to 3547±21 Ma (2σ), much older than the whole-rock age of the same meteorite (~3.02±0.03 Ga). The other baddeleyite grain in LAP 02224 has an age of 3005±17 Ma (2σ). The result indicates that the minimum crystallization age of LAP 02224 is ~3.55 Ga and the younger ages could reflect late thermal disturbance on U-Pb system.

    Proline is the important osmotic regulation substances in plants and plays a critical role in improving the stress tolerance of plants. The materials is Lycium chinense Miller, which proline content changes significantly after salt stress. After 1.5% NaCl stress, full length cDNA sequence of a putative Al-pyrroline-5-carboxylate synthase gene( P5CS) was cloned from Lycium chinense Miller leaves using RT-PCR and 3' rapid amplification of cDNA ends ( RACE), named LmP5CS, and construct expression vector pH7m24GW, 3rc -LmP5CS. Sequence analysis showed that the complete open reading frame (ORF) of this gene is 2154 bp, encoding for a protein of 717 amino acids with an isoelectric point of 6.07 and a molecular weight of 77.5 kDa. After 200 mmol / L NaCl stress, protein expression level increased at first and decreased subsequently, proline content changed in accordance with that. The semi-quantitative PCR result suggests that LmP5CS plays an important role in proline content change responses to salt stress.%目的:为进一步研究枸杞抗逆境胁迫的机制,并为转基因育种,提供理论依据.提高农作物的抗逆性提供优质的基因资源.方法:提选取盐胁迫后脯氨酸含量变化较大的耐盐植物枸杞为材料,用1.5% NaCl处理后,提取枸杞叶片总RNA,利用RT-PCR及3′RACE方法克隆获得吡咯啉-5-羧酸合成酶(delta 1-pyrroline-5-carboxylate synthetase,P5CS)基因的全长cDNA,命名为LmP5 CS,构建pH7m24GW,3 rc-LmP5 CS植物表达载体.结果:LmP5 CS基因的ORF长2 154 bp,编码1个等电点为6.07、分子量为77.5kDa、由717个氨基酸组成的蛋白.枸杞在200 mmol/LNaCl盐胁迫下,LmP5CS基因表达量随处理时间,有先升高后降低的趋势,9h基因表达量最高,脯氨酸含量变化与之一致.结论:LmP5 CS基因在盐胁迫下脯氨酸含量的变化中起关键作用.

    Chromones and pyrones are the major secondary metabolites of Aloe barbadensis Miller. As they are minor components of the plant, an efficient purification procedure for them is of great importance for promoting their pharmacological studies. To develop efficient methods for one-step separation and purification of two chromones (5-((S)-2'-oxo-4'-hydroxypentyl)-2-hydroxymethylchromone (1) and 5-((4E)-2'-oxo-pentenyl)-2-hydroxymethylchromone (3)) and one pyrone (aloenin aglycone (2)) from A. barbadensis via reversed-phase flash chromatography (RP-FC) and high-speed counter current chromatography (HSCCC). The RP-FC separation was performed using methanol:water (26:74, v/v) as the mobile phase at a flow rate of 20 mL/min. A solvent system composed of dichloromethane:methanol:water (3:1.5:1, v/v/v) was used for the HSCCC separation, at a flow rate of 2.0 mL/min. A one-step RP-FC operation within 110 min was successfully used for the purification of compounds 1 (27.9 mg, 96.5%), 2 (32.4 mg, 98.2%) and 3 (4.1 mg, 99.0%) from 129 mg of crude sample, and a one-step HSCCC separation within 95 min was successfully implemented for the purification of compounds 1 (31.1 mg, 97.6%), 2 (35.8 mg, 96.7%) and 3 (2.7 mg, 98.1%) from 134 mg of crude sample. The developed procedures were efficient, with low cost and high yield, which would afford sufficient amounts of high-purity compounds for chromatographic purposes and pharmacological activity screening.

    The encoding method proposed by Miller et al. lacks scalability and requires that the number of neurons be fixed in advance. It is a binary-code and uses an adjacency matrix to represent the topology of an ANN but cannot encode weights. All of these restrict its use, so this paper presented a modified Millermatrix encoding scheme, which adopts real-code and can largely reduce the redundance of encoding. This encoding method is used in the proposed evolutionary ANN. The results show that it is effective.%Miller等人提出的矩阵编码方法要求神经元的数目预先固定,且基因数目是神经元数目的平方.另外,它是一种二进制编码,使用矩阵表示的网络结构却无法编码权值,从而限制了它的使用.提出了改进的Miller矩阵编码方法,该方法采用实数编码,可大大减小编码的冗余,能用于神经元数目在一定范围内可变的场合.所设计的进化神经网络经实际应用取得了很好的结果,表明该方法是有效的.

    Extracts from the leaves of the Aloe vera plant (Aloe barbadensis Miller) have long been used as herbal remedies and are also now promoted as a dietary supplement, in liquid tonics, powders or tablets, as a laxative and to prevent a variety of illnesses. We studied the effects of Aloe vera extract on rats and mice to identify potential toxic or cancer-related hazards. We gave solutions of nondecolorized extracts of Aloe vera leaves in the drinking water to groups of rats and mice for 2 years. Groups of 48 rats received solutions containing 0.5%, 1% or 1.5% of Aloe vera extract in the drinking water, and groups of mice received solutions containing 1%, 2%, or 3% of Aloe vera extract. Similar groups of animals were given plain drinking water and served as the control groups. At the end of the study tissues from more than 40 sites were examined for every animal. In all groups of rats and mice receiving the Aloe vera extract, the rates of hyperplasia in the large intestine were markedly increased compared to the control animals. There were also increases in hyperplasia in the small intestine in rats receiving the Aloe vera extract, increases in hyperplasia of the stomach in male and female rats and female mice receiving the Aloe vera extract, and increases in hyperplasia of the mesenteric lymph nodes in male and female rats and male mice receiving the Aloe vera extract. In addition, cancers of the large intestine occurred in male and female rats given the Aloe vera extract, though none had been seen in the control groups of rats for this and other studies at this laboratory. We conclude that nondecolorized Aloe vera caused cancers of the large intestine in male and female rats and also caused hyperplasia of the large intestine, small intestine, stomach, and lymph nodes in male and female rats. Aloe vera extract also caused hyperplasia of the large intestine in male and female mice and hyperplasia of the mesenteric lymph node in male mice and hyperplasia of the stomach

    Two soils from Cauca Department (Colombia were pasteurized; soil analysis showed that they contained 3.0 and 9.0 ppm P, pH 4.8 and 6.2, respectively. They were fertilized with 0, 30 and 60 kg P/ha. Tomato plantlets var. Chonto Santa Cruz were inoculated with 11 VAM isolates of the CIAT VAM fungal germplasm and one VAM native fungi. Plantlets were grown in pots. Fifty two days after plants were harvested and height, dry matter, tissue analysis tor N, P, K, Ca, Mg and B was performed; fungus infection and health were determined. The statistical analysis showed that the major differences in this bioassay were due to a type of soils and their nutritional conditions. Plant dry matter and height increased with the increased levels of fertilizer. Best grow results were obtained with 60 kg P/ha. Dry matter, heigth and nutrient uptake (N, P, K, Ca and B were significantly different between introduced VAM and the native fungi. VAM fungi isolates had different behavior in each soil. This confirmed the soil influence in the symbiosis effectiveness.

    En condiciones de invernadero, en dos suelos del Departamento del Cauca (Colombia, previamente pasteurizados, con contenidos de P de 3.0 y 9.0 ppm y pH de 4.8 y 6.2 respectivamente, sujetos a fertilización con O, 30 y 60 kg de P/ha, se probaron 11 cepas de hongos micorrizógenos provenientes de diferentes regiones del país y con la flora nativa de cada suelo. Las plantas se cosecharon a los 52 días de transplante y se les determinó altura, materia seca, análisis foliar de N, P, K. Ca, Mg y B, infección por hongos micorrizógenos y sanidad del cultivo. Las mayores diferencias en este ensayo se debieron al tipo de suelo y sus condiciones nutricionales. La materia seca y altura de las plantas aumentaron en ambos suelos, al incrementarse la fertilización, los mejores resultados en desarrollo vegetativo y reproductivo ocurrieron con 60 kg de P/ha. En materia seca, altura y absorción de N, P, K, Ca, y B, hubo diferencias altamente significativas entre cepas introducidas y flora nativa. Las cepas variaron en su comportamiento en los 2 suelos, lo cual corrobora la alta influencia de este factor en la efectividad de la simbiosis.

    In the book of On Nationality professor Miller forms perfect-ly the perspective of political theory which is based on the principle of na-tionality.And in his citation and interpretation of Rawls’s theory of justice he lets us know that justice society in Rawls’s theory is of nationality.In the meanwhile he provides a reference for us to understand the international po-litical order view based on Rawls’s theory of the Law of Peoples the refer-ence that is of the international political order view based on the principle of nationality.However there are some problems of Miller ’s interpretation of Rawls’s theory of justice for example he thinks that Rawls’s theory of justice is a kind of specific political theory delt with practical issues;he failes to un-derstand the jump or coherence between Rawls’s dometic theory of justice and Rawls’s international theory of justice and so on.%在《论民族性》中,戴维・米勒教授有力地展现了一种基于民族性原则的政治学理论视镜。在对罗尔斯正义理论的征引和解读中,米勒教授一方面基于其民族性理论视镜让我们有幸获得了他对罗尔斯教授所说之“正义社会的性质是什么”这一问题的个殊性回答,即罗尔斯教授的正义社会具有民族性;进而另一方面,他还为我们理解罗尔斯万民法主导下的国际政治秩序观提供了一个米勒版参照,即基于民族性原则的国际政治秩序观。不过,米勒教授对罗尔斯正义理论的解读也存有一些问题,比如将罗尔斯理论视为一种应对现实问题的具体政治理论、未能理解罗尔斯教授国内和国际正义理论之间的跳跃性或连贯性等。

Kuntze 1891 subsp. hungaricum (Klokov Soó is Pannonian endemic subspecies that inhabits continental halobiomes, while Limonium anfractum (Salmon Salmon 1924 is one of the indicators of halophyte vegetation of marine rocks and its distribution is restricted to the southern parts of Mediterranean Sea coast. In this work, micromorphological and anatomical characters of leaves of these two Limonium taxa were analyzed, in order to examine their adaptations to specific environmental conditions on saline habitats. The results showed that both taxa exhibited strong xeromorphic adaptations that reflected in flat cell walls of epidermal cells, thick cuticle, high palisade/spongy tissue ratio, high index of palisade cells, the presence of sclereid idioblasts in leaf mesophyll and mechanical tissue by phloem and xylem. Both taxa are crynohalophytes and have salt glands on adaxial and abaxial epidermis for excretion of surplus salt. Relatively high dimensions of mesophyll cells, absence of non-glandular hairs and unprotected stomata slightly increased above the level of epidermal cells, are also adaptations to increased salinity.

    Zinc ultrafine powders (UFPs) with the average particle size of 0.175 to 1.24 μm are synthesized via the flow-levitation method. The peculiarities of the formation of zinc UFPs are considered with respect to the carrier gas properties (heat capacity, thermal conductivity, and diffusion coefficient), as well as the gas flow parameters (pressure and flow rate). The obtained zinc particles are studied via scanning electron microscopy and X-ray diffraction. The factors determining the crystal structure of zinc particles and their size distribution are discussed as well. The data on oxidation of zinc stored in unsealed containers under normal conditions are also presented.

  7. Brief Comments on "The Shapiro Conjecture, Prompt or Delayed Collapse ?" by Miller, Suen and Tobias

    CERN Document Server

    Shapiro, S L

    1999-01-01

    Recent numerical simulations address a conjecture by Shapiro that when two neutron stars collide head-on from rest at infinity, sufficient thermal pressure may be generated to support the hot remnant in quasi-static equilibrium against collapse prior to neutrino cooling. The conjecture is meant to apply even when the total remnant mass exceeds the maximum mass of a cold neutron star. One set of simulations seems to corroborate the conjecture, while another, involving higher mass progenitors each very close to the maximum mass, does not. In both cases the total mass of the remnant exceeds the maximum mass. We point out numerical subtleties in performing such simulations when the progenitors are near the maximum mass; they can explain why the simulations might have difficulty assessing the conjecture in such high-mass cases.

    Full Text Available Pereskia aculeata Mill. (Ora-pro-nóbis is a native cactaceae from tropical America, whose leaves have high protein content. In Brazil it is found in all territorial extension between the states of Bahia and Rio Grande do Sul. Most studies have focused on chemical characterization of the leaves of this specie. The objective was to assess the carotenoids profile and the total polyphenols present in the fruits of P. aculeate. Carotenoids were determined by HPLC-PAD (high performance liquid chromatography - photodiode array detector, total polyphenols were determined by Folin-Ciocalteu and vanillin methods. Trans-β-carotene was the main carotenoid, followed by α-carotene, lutein and other minor carotenoids. It was found 64.9 ± 1.1 mg.100g-1 of gallic acid equivalent, 14.8 ± 0.2 mg.100g-1 of catechin equivalent. Carotenoid identification of P. aculeate fruits are presented here by the first time and indicate that these fruits can be researched as source of bioactive substances, especially antioxidant and provitamin A carotenoids.

    Pleural plaques among pumice workers on Lipari Island have been described and the Authors have suggested the hypothesis that such biological effect could be related to the particles' morphology characterized by the presence of elements similar to fibers. Analysis on compact bulk materials and on dust samples from different sites of the Island have been performed to obtain information on the chemical composition of such materials. The Scan Electron Microscopy (SEM) analyses confirm the presence of fibrous particles with a chemical structure similar to the Refractory Ceramic Fibers (RCF) composition. These results could explain the presence of plural plaques among the workers and new clinical and epidemiological evaluations of the potential effects associated to this exposure are needed.

    A content analysis of research published in the Journal of Counseling Psychology (JCP) was conducted for Volumes 46 (1999) through 56 (2009). The analysis involved the placement of 514 articles in 15 substantive content categories. In addition, we identified the most frequently published authors, most frequent institutional affiliations, and several reported demographic characteristics. The principal areas of research activity in the JCP were multiculturalism and/or diversity, research on development and evaluation of tests and measures, personality and adjustment, outcome research, and interpersonal and/or social support and/or attachment, with these categories accounting for 57% of the articles published. Over 40% of the samples reported were college students, with a large number of samples including both genders and indicating the ethnic breakdown. This content analysis revealed that the JCP has remained consistent with its stated mission while incorporating changes in the field in its publications.

  19. A cohort study of uranium millers and miners of Grants, New Mexico, 1979-2005

    A cohort mortality study of workers engaged in uranium milling and mining activities near Grants, New Mexico, during the period from 1955 to 1990 was conducted. Vital status was determined through 2005 and standardised mortality ratio (SMR) analyses were conducted for 2745 men and women alive after 1978 who were employed for at least six months. Overall, mortality from all causes (SMR 1.15; 95% CI 1.07-1.23; n = 818) and all cancers (SMR 1.22; 95% CI 1.07-1.38; n = 246) was greater than expected on the basis of US mortality rates. Increased mortality, however, was seen only among the 1735 underground uranium miners and was due to malignant (SMR 2.17; 95% CI 1.75-2.65; n = 95) and non-malignant (SMR 1.64; 95% CI 1.23-2.13; n = 55) respiratory diseases, cirrhosis of the liver (SMR 1.79; n = 18) and external causes (SMR 1.65; n = 58). The lung cancer excess likely is attributable to the historically high levels of radon in uranium mines of the Colorado Plateau, combined with the heavy use of tobacco products. No statistically significant elevation in any cause of death was seen among the 904 non-miners employed at the Grants uranium mill. Among 718 mill workers with the greatest potential for exposure to uranium ore, no statistically significant increase in any cause of death of a priori interest was seen, i.e., cancers of the lung, kidney, liver, or bone, lymphoma, non-malignant respiratory disease, renal disease or liver disease. Although the population studied was relatively small, the follow-up was long (up to 50 yrs) and complete. In contrast to miners exposed to radon and radon decay products, for uranium mill workers exposed to uranium dusts and mill products there was no clear evidence of uranium-related disease.

    Density functional theory (DFT) calculations combined with surface thermodynamic arguments and the Gibbs-Curie-Wulff equilibrium morphology formalism have been employed to explore the effect of the reaction conditions, temperature (T), and gas-phase partial pressures (PH2 and PH2S) on the stability of nickel sulfide (Ni3S2) surfaces. Furthermore, the strength and nature of chemical bonds for selected Ni3S2 surface cuts were investigated with the quantum theory of atoms in molecules methodology. A particular analysis of the electrostatic potential within this theoretical framework is performed to study the potential activity of nickel sulfide nanoparticles as hydrodesulfurization (HDS) catalysts. The calculated thermodynamic surface stabilities and the resulting equilibrium morphology model suggest that unsupported Ni3S2 nanoparticles mainly expose (111) and (111) type surface faces in HDS conditions. Analysis of the electrostatic potential mapped onto a selected electron density isocontour (0.001 au) on those expose surface reveals a poor potential reactivity toward electron-donating reagents (i.e., low Lewis acidity). Consequently, a very low attraction between coordinatively unsaturated active sites (Lewis sites) exposed at the catalytic particles and the S atoms coming from reagent polluting molecules does inactive these kinds of particles for HDS.

    A first approximation to the inheritance of cotyledon storage proteins was studied in European sweet chestnut (Castanea sativa Mill.) by evaluating the offspring of a controlled cross between two local chestnut varieties (Corriente and Pilonga) from southern Spain. The analysis was carried out in 15 polymorphic bands corresponding to the albumin fraction of the storage proteins. The relationship between bands displayed one case of allelism and four of linkage. These results should be considered as the baseline of the genetics of these proteins and suggest that they could be useful for the evaluation of the genetic variability in chestnut.

    This study has been to analyse the useful nut globulin proteins as a marker of the genetic diversity in Castanea sativa. The evaluated populations were highly polymorphic for the globulins, being detected up to 35 polymorphic bands with a wide distribution among all the evaluated populations. Taken together for populations from all the chestnut regions, about 39.3% of total allelic variation was distributed among the populations. The estimates of genetic similarity between populations were clearly associated with the collecting site. This method of analysis of the nut storage proteins (globulins) could be a useful tool for the evaluation of genetic diversity in this and other species of the Fagaceae.

    Eruca is thought to be an excellent source of antioxidants like phenolic compounds, carotenoids, glucosinolates and their degradation products, such as isothiocyanates. Sulforaphane is one of the most potent indirect antioxidants of Eruca isolated until the date. In this work we investigate: (i) the safety and DNA protective activity of Eruca extracts and sulforaphane (under and without oxidative stress) in Drosophila melanogaster; and (ii) the influence on D. melanogaster life span treated with Eruca extracts and sulforaphane. Our results showed that among the four concentrations of Eruca extracts tested (from 0.625 to 5mg/ml), intermediate concentrations of the Es2 accession (1.25 and 2.5mg/ml) exhibited no genotoxic activity, as well as antigenotoxic activity (inhibition rate of 0.2-0.6) and the lowest concentration of Es2 and Es4 accessions (0.625 mg/ml) also enhanced the health span portion of the live span curves. Sulforaphane presented a high antigenotoxic activity in the SMART test of D. melanogaster and intermediate concentrations of this compound (3.75 μM) enhanced average healthspan. The results of this study indicate the presence of potent antigenotoxic factors in rocket, which are being explored further for their mechanism of action.

  8. Growth characteristics and response to climate change of Larix Miller tree-ring in China

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    As one of the earliest species used in dendrochronological studies, Larix responds sensitively to climate change. In this study, nine larch species and one variety from eleven sites were collected to study the growth characteristics of tree-ring width using dendrochronological methods. Ten residual tree-ring chronologies were developed to analyze their relationships with regional standardized anomaly series by Pearson’s correlation analysis. The results suggest that most of the chronologies had significantly positive correlations with the mean temperature and mean maximum temperature in May. The spring temperature evidently limited the radial growth of the larch species without precipitation control. The largest mean tree-ring width was found in Himalayan Larch in Jilong, whereas Master Larch in Si’er reflected the smallest mean value. Both species presented little climate information in this study. Chinese, Potanin, and Tibetan larches are significantly correlated with climate change, implying a huge potential for climate history reconstruction. The elevation of the sampling sites appears to be an important condition for tree-ring growth of larches responding to climate factors.

    2009-03-01

    We have specifically carried out a greenhouse experiment to assess relationship between samara weight and seed success. Relationship assessed as dispersal potential, germination level, germination rate and early seedling mass for the invasive species Ailanthus altissima. For this purpose, we considered two close stands as seeds source. We found no correlation between samara size and neither germination level, germination rate, nor seedling mass, but a positive correlation with samara projected area. These results suggest that samara weight is not directly related to germination, dispersal and invasion potential neither. Nevertheless, stands differed in the invasion potential of their samaras; one stand presented samaras with higher projected area per weight unit whereas the other one presented samaras that produced heavier seedlings. Whatever the origin, (genetic or environmental) of this differences it should be advantageous for a colonizing invader species such as A. altissima since it could imply a wider range of habitats susceptible to invasion.

    Full Text Available The aim of this study was to extract mucilage from O. cochenillifera (L. cacti and determine its functional and physicochemical properties. The best mucilage yield (31% was obtained by nonthermal extraction with hydration. The mucilage has appreciable carbohydrate and protein contents. The phytochemical analysis shown the presence of alkaloids and terpenes/steroids. The Fourier transformed infrared (FT-IR spectrum of the mucilage exhibits typical bands for carbohydrates as O–H, C–H, and –COO−. The mucilage demonstrated water- and oil-holding capacities of 2.78 g water/g dry mucilage and 1.80 g oil/g dry mucilage, respectively, these properties can have a positive effect on the texture of the products when used as a stabilizer. The mildly acidic pH (4.8–5 contributes to its emulsifying capacity. The presence of electrolytes in the mucilage can be of great value in flocculation processes. The mucilage forms low viscosity solutions in the same manner as gum Arabic. Finally, its potential for use as a textile dye remover was evaluated, achieving a 70% removal rate from aqueous solutions. The prepared mucilage exhibits properties that recommend it as a natural material that can be used as an additive in the chemical, food, pharmaceuticals and cosmetics industries, as well as in decontamination processes.

    Aloe has been widely used in food products, pharmaceuticals, and cosmetics because of its aromatic and therapeutic properties. In the present study, the ethanolic extracts of aloe gel were gamma-irradiated from 10 to 100 kGy. After gamma irradiation, the color of the ethanolic extracts of aloe gel changed to red; this color persisted up to 40 kGy but disappeared above 50 kGy. Liquid chromatography/mass spectrometry analysis demonstrated the production of a new, unknown compound (m/z=132) after gamma irradiation of the ethanolic extracts of aloe gel. The amount of this unknown compound increased with increasing irradiation up to 80 kGy, and it was degraded at 100 kGy. Interestingly, it was found that gamma irradiation significantly increased the antioxidant activity, as measured by the 1,1-diphenyl-2-picrylhydrazyl-radical scavenging capacity. The antioxidant activity of aloe extract was dramatically increased from 53.9% in the non-irradiated sample to 92.8% in the sample irradiated at 40 kGy. This strong antioxidant activity was retained even at 100 kGy. These results indicate that gamma irradiation of aloe extract can enhance its antioxidant activity through the formation of a new compound. Based on these results, increased antioxidant activity of aloe extracts by gamma rays can be applied to various industries, especially cosmetics, foodstuffs, and pharmaceuticals.

The aim of this study was to investigate the influences of two drying methods on the antioxidant activity of the quince. Materiał and methods. Fifty two fresh Iranian ąuinces (Cydonia oblonga were obtained from different parts of Shiraz. Half of the ąuinces were peeled and both peel and flesh immediately frozen at -20°C individually. The remainder was divided in two groups, and dried with sun and oven drying methods. Proximate analysis, caloric, minerał and vitamin C contents were determined in the fresh ąuinces. The total phenolic, DPPH radical scavenging activity and reducing power analysis were done on flesh, peel, sun-dried and ovendried ąuinces. Results. The proximate and nutritional composition of the fresh ąuinces was similar to those reported by other researchers. Oven-dried and ąuince peel contained higher amounts of phenolics than the sun-dried and flesh ąuinces, respectively. Sun-dried and flesh samples showed lower radical scavenging effect and reducing antioxidant capacity than oven-dried and ąuince peel, respectively. Conclusion. Overall, oven drying can better preserve the antioxidative activity of the ąuince.

    The C14:C12 ratio of atmospheric CO2 (expressed as Delta 14C) is the gold standard measurement to derive the portion of observed atmospheric CO2 gradients resulting from combustion of fossil fuels (CO2-ff). This is because fossil fuels are devoid of 14C, unlike all other sources and sinks that impact atmospheric Delta14C. With enough 14C measurements, independent, 'top-down', estimation of US fossil fuel-CO2 emissions should be possible. However, our ability to make carbon-14 measurements is severely constrained by cost, accessibility to accelerator mass spectrometers (AMS) and the volume of air required to make high precision (~0.2 %) measurements of 14CO2 (mixing ratio is ~ 4e-16 mol/mol). Thus, Delta 14C is currently measured in only a small subset of NOAA/ESRL Global Monitoring Division (GMD) tall-tower and aircraft air samples. Here, we present a Projection Pursuit Regression (PPR) model to predict CO2-ff measured at different times and altitudes in terms of surrogate gases that are more widespread and relatively inexpensive to measure. This method would, in effect, allow expansion of Delta 14C measurements by factor of ~3 or 4 throughout North America. To create a proxy for CO2-ff, we take advantage of the observed correlations between (Delta 14C-derrived) CO2-ff and regional-scale enhancements of a wide array of anthropogenic gases, like CO, SF6, and halo- and hydro-carbons. We select the complexity and form of the PPR model by cross validation where validation data prediction error is minimized. In cross validation, the prediction model is based on the training data and not the validation data. We quantify prediction model performance with test data excluded from the model development process. According to cross validation, the PPR model is superior to a simpler linear model. Comparison with test CO2-ff data shows that CO2-ff can be predicted with a root mean square error of 1.1 ppm, only slightly higher than the Delta 14C-precision limit for CO2-ff of 1 ppm. Applying the PPR model to the large NOAA/ESRL/GMD database of surrogate gases, we can create a large set of synthetic CO2-ff data for the US. Finally, we will discuss the application of this large data set of lower-precision CO2-ff to top down determination of US fossil fuel CO2 emissions by presenting results from an Observation System Simulation Experiment (OSSE).

    Full Text Available Identificar o impacto da salinidade no desenvolvimento e crescimento de espécies resistentes a altas concentrações salinas é de fundamental importância para a recuperação de áreas salinizadas do semiárido nordestino brasileiro. Visando contribuir para a resolução desta problemática, o presente trabalho avaliou o efeito de diferentes níveis de salinidade para o desenvolvimento e o crescimento da carnaúba, espécie nativa e de extremo valor econômico para a região. Os níveis analisados foram: 0, 25, 50, 100 mM de NaCl, correspondente a uma condutividade elétrica de 2.0, 4.6, 7.1, 9.6, 12 dS m-1, respectivamente. Utilizou-se o delineamento inteiramente casualisado, com cinco tratamentos e quatro repetições, e se analisaram as variáveis altura da parte aérea, largura da parte aérea da folha, comprimento da raiz principal, peso da matéria seca, razão da matéria seca parte aérea/raiz e taxa de sobrevivência. Os tratamentos com 25 e 50 mM de NaCl não afetaram a sobrevivência inicial da planta. Concentrações maiores ou iguais que 75 mM de NaCl reduziram a produção de biomassa e a taxa de sobrevivência, em quase 50%; portanto, a produção de plantas nesses níveis de sal não é recomendada.To identify the impact of salinity on the development and growth of species resistant to high salt concentration is fundamental for restoration of salty areas in the Northeast brazilian semi-arid region. Seeking to solve this problem this work evaluated the effect of different salt levels on the development and growth of ‘carnauba’, a native species with high economical value to the region. The levels analyzed were: 0, 25, 50, 75 and 100 mM of NaCl, corresponding to an electrical conductivity of 2.0, 4.6, 7.1, 9.6 and 12 dS m-1, respectively. A completely randomized experimental design with five treatments and four replicates was used. The analyzed variables were aerial height, aerial width, main root length, dry weight, aerial/root ratio and survival rate. Treatments with 25 and 50 mM of NaCl did not affect the initial plant survival. Concentration levels greater or equal to 75 mM of NaCl reduced the biomass production and the survival rate in almost 50%. Therefore, plant production at these salt levels is not recommended.

    Primitive carbonaceous chondrites contain a wide variety of organic material, ranging from soluble discrete molecules to insoluble nanoglobules of macro-molecular carbon. The relationship between the soluble organic molecules, macromolecular organic material, and host minerals are poorly understood. Large H, C and N isotopic anomalies suggest some organic components formed in low-T interstellar or outer Solar System environments. The highest isotope anomalies occur in m-scale inclusions in the most primitive materials, such as cometary dust and the least altered carbonaceous chondrites. Often, the hosts of these isotopically anomalous 'hotspots' are discrete organic nanoglobules that probably formed in the outermost reaches of the protosolar disk or cold molecular cloud. Molecular and isotopic studies of meteoritic organic matter are aimed at identifying the chemical properties and formation processes of interstellar organic materials and the subsequent chemical evolutionary pathways in various Solar System environments. The combination of soluble and insoluble analyses with in situ and bulk studies provides powerful constraints on the origin and evolution of organic matter in the Solar System. Using macroscale extraction and analysis techniques as well as microscale in situ observations we have been studying both insoluble and soluble organic material in primitive astromaterial samples. Here, we present results of bulk C and N isotopic measurements and coordinated in situ C and N isotopic imaging and mineralogical and textural studies of carbonaceous materials in a Cr2 carbonaceous chondrite. In accompanying abstracts we discuss the morphology and distribution of carbonaceous components and soluble organic species of this meteorite.

    2009-07-01

    Thirty eight traditional chestnut cultivars, from a contemporary collection, were described using nine characteristics, seven of which are included in the guidelines for carrying out tests of distinctness, homogeneity and stability of chestnut established by the International Union for the Protection of New Varieties of Plants (UPOV). The nine variables were chosen from among 13 characteristics evaluated in the collection with regard to the criteria for distinctness, uniformity and stability. The evaluations were carried out over the years 2003, 2004 and 2005, in two plantations, situated in the northwest of the Iberian Peninsula. Each mean value obtained for each cultivar, plantation and year were assigned a state and numerical number using the UPOV system or proposed new descriptors. No cultivar showed a very late time of leaf bud burst nor a very late time for the start of male and female flowering, nor a strong penetration of the seed coat into embryo. In five variables there was no or few differences among years and between plantations. Consequently they can be evaluated at one site in one year. These characters were: filament length of male flowers, percent of chestnuts with a split pericarp, the degree of penetration of the seed coat into the embryo, fruit shape and the ratio of hilum length to hilum width. Of the remaining four variables, three were phonologic (time of leaf bud burst, time of beginning of male and female flowering) and one related to fruit size (size of fruit hilum). They varied among years and between plantations and consequently need to be evaluated under contrasting site conditions for a minimum number of years. Additional key words: cultivated varieties, descriptor, genetic resources, UPOV. (Author) 27 refs.

    2013-03-01

    Full Text Available The aim of this study was to evaluate the influence of high hydrostatic pressure (150, 250, 350, 450, and 550 MPa, applied for 5 minutes, on antioxidant capacity, total phenolic content, color, firmness, rehydration ratio, and water holding capacity of aloe vera gel stored for 60 days at 4 °C. The analyzed properties of the pressurized gel showed significant changes after the storage period. The highest value of total phenolic content was found at 550 MPa. However, a decrease in the antioxidant capacity was observed for all pressurized gel samples when compared to the control sample (p < 0.05. The smallest changes in product color were observed at pressure levels between 150 and 250 MP. The application of high hydrostatic pressure resulted in lower gel firmness, and the lowest value was found at 150 MPa (p < 0.05. On the other hand, the untreated sample showed a greater decrease in firmness, indicating that high pressure processing preserves this property. The application of high hydrostatic pressure exhibited modifications in the food matrix, which were evaluated in terms of rehydration ratio and water holding capacity.

    Rocket is an important source of essential elements. However, it may also accumulate toxic elements such as metal(oids). The objectives of the present work were (i) to study the uptake of arsenic, lead, cadmium and zinc in rocket grown in contaminated soils, (ii) to establish the genotoxic and cytotoxic activities of this vegetable material, and (iii) to study the modulator role of the glucosinolate and metal contents in the genotoxic/cytotoxic activities. Lead, cadmium and zinc leaf concentrations in our study were over the concentrations allowed by the statutory limit set for metal(oid) contents in vegetables. The accessions were non genotoxic at the different concentrations studied, although one of the accessions showed the highest mutation rates doubling those of negative control. The cytotoxicity assays with HL60 human leukaemia cells showed that the tumouricide activities of rocket leaves decreased with the increasing of metal(oid) concentrations and also with the decreasing of glucosinolate concentrations in their tissues. An interaction between metal(oid)s and glucosinolate degradation products contained in rocket leaves is suggested as the main modulator agents of the biological activity of the plants grown in metal-contaminated soils.

    Background: Annona cherimola, known as “chirimoya” has been reported in Mexican traditional medicine for the treatment of diabetes. Objective: The aims of the present study were to validate and assess the traditional use of A. cherimola as an antidiabetic agent. Materials and Methods: The ethanol extract from A. cherimola (300 mg/kg, EEAc), subsequent fractions (100 mg/kg), and rutin (30 mg/kg) were studied on alloxan-induced type 2 diabetic (AITD) and normoglycemic rats. In addition, oral glucose tolerance test (OGTT) and oral sucrose tolerance test (OSTT) were performed in normoglycemic rats. Molecular docking technique was used to conduct the computational study. Results: Bioassay-guided fractionation of EEAc afforded as major antihyperglycemic compound, rutin. EEAc attenuated postprandial hyperglycemia in acute test using AITD rats (331.5 mg/dL) carrying the glycemic levels to 149.2 mg/dL. Rutin after 2 h, attenuated postprandial hyperglycemia in an acute assay using AITD rats such as EEAc, with maximum effect (150.0 mg/dL) being seen at 4 h. The antihyperglycemic activities of EEAc and rutin were comparable with acarbose (151.3 mg/dL). In the subchronic assay on AITD rats, the EEAc and rutin showed a reduction of the blood glucose levels since the 1st week of treatment, reaching levels similar to normoglycemic state (116.9 mg/kg) that stayed constant for the rest of the assay. OGTT and OSTT showed that EEAc and rutin significantly lowered blood glucose levels in normoglycemic rats at 2 h after a glucose or sucrose load such as acarbose. Computational molecular docking showed that rutin interacted with four amino acids residues in the enzyme α-glucosidase. Conclusion: The results suggest that rutin an α-glucosidase inhibitor was responsible in part of the antihyperglycemic activity of A. cherimola. Its in vivo antihyperglycemic activity is in good agreement with the traditional use of A. cherimola for the treatment of diabetes.

    Callus cultures from cotyledon explants were established and maintained in culture for more than two years. After several months callus cultures were transferred into liquid medium and cultured as cell suspensions. Protoplasts were isolated from these cell suspension cultures and cultured in a liquid medium. After formation of new cell walls the cells were further cultured in liquid medium and afterwards transferred to an agar-solidified medium to give a vigorously growing callus culture. In the case of the cultivar 'Lukullus' shoots were recovered from callus. All efforts to root these shoots failed and this, in addition to variations in appearence, suggests that the shoots are changed genetically possibly due to the prolonged culture period.

    In Colombia, especially in the Atlantic Coast it is produced and marketed the costeño cheese, an indigenous product of the gastronomy of this region, but the prolonged exposure of this product to the environment leads to microbial contamination and non-enzymatic rancidity. For this reason the transmittance of an edible coating based in aloe vera gel and cassava starch to preserve costeño cheese was evaluated using trifurcated optical fibers. The results become a tool for the selection of treatments in making edible films and their subsequent use in coatings for various types of food products.

    Lippia alba (Verbenaceae) is a shrub whose essential oil has important biological, pharmacological, and aromatizing properties. The species has a natural range from Central America to Argentina, being cultivated for its commercial value in Brazil, Argentina and Guatemala, and has been introduced into India and Spain. To reach the economic potential of the plant, the present study was aimed at evaluating L. alba for different chemotypes. The composition of the essential oil from two native populations of L. alba, collected from Argentina and two accessions from Costa Rica, were screened by GC and GC-MS. The results obtained led us to adopt the concept of a biodistribution map, as was proposed previously for the species, representing an approach to the natural biological distribution of the species in America based on the chemotypes described and their geographical distribution. Moreover, the biodiversity reported for the species (seven of eight chemotypes described for L. alba are present in Argentina) suggests the southern region of South America as the centre of distribution for L. alba.

    Full Text Available The present case describes an adult female Zoogoneticus tequila showing a congenital, marked shortening with left deviation of the upper and lower jaws, in association with microphthalmia of the left eye. The fish was normally fed and had a normal reproductive behaviour. After spontaneous death occurred at an advanced age, the fish was submitted for necropsy examination, which revealed the presence of an oval, 1 cm × 0.5 cm × 0.5 cm in size, cystic structure containing clear amber fluid, located in the coelomic cavity, in place of the spleen. Histopathological examination revealed multiple cystic spaces empty or filled with a slightly eosinophilic, homogenous, proteinaceous material, and lined by flattened, vimentin-positive endothelial-like cells. Residual parts of splenic tissue were also admixed with cystic spaces, suggesting a final diagnosis of cystic lymphangiomatosis of the spleen, which has not been previously described in fish. This is the first report of multiple, life-compatible, congenital physical deformities in association with splenic lymphangiomatosis in Zoogoneticus tequila.

    Along with dehydration, the development of insects and microorganisms is the major drawback in chestnut conservation. Irradiation has been regaining interest as an alternative technology to increase food product shelf life. In the present work, the effects of low dose gamma irradiation on the sugar, fatty acid, and tocopherol composition of chestnuts stored at 4 °C for different storage periods (0, 30, and 60 days) was evaluated. The irradiations were performed in a 60Co experimental equipment, for 1 h (0.27±0.04 kGy) and 2 h (0.54±0.04 kGy). Changes in sugars and tocopherols were determined by high performance liquid chromatography coupled to refraction index and fluorescence detections, respectively, while changes in fatty acids were analyzed by gas-chromatography coupled to flame ionization detection. Regarding sugar composition, storage time proved to have a higher effect than irradiation treatment. Fructose and glucose increased after storage, with the corresponding decrease of sucrose. Otherwise, the tocopherol content was lower in nonirradiated samples, without a significant influence of storage. Saturated, monounsaturated, and polyunsaturated fatty acids levels were not affected, either by storage or irradiation. Nevertheless, some individual fatty acid concentrations were influenced by one of two factors, such as the increase of palmitic acid in irradiated samples or the decrease of oleic acid after 60 days of storage. Overall, the assayed irradiation doses seem to be a promising alternative treatment to increase chestnut shelf life, without affecting the profile and composition in important nutrients.

  19. Exsolution of Iron-Titanium Oxides in Magnetite in Miller Range (MIL) 03346 Nakhlite: Evidence for Post Crystallization Reduction in the Nakhlite Cumulate Pile

    2012-01-01

    MIL 03346 is one of the most mesostasis-rich nakhlites [1] and thought to have equilibrated at oxygen fugacities near the fayalite-magnetite-quartz oxygen (FMQ) buffer ([2,3]). Studies of FeTi oxides in nakhlites have led to additional constraints on their equilibration temperatures and fO2s [4,5,6,7]. Comparison of these results to fO2s calculated for shergottites indicates that nakhlites are among the most oxidized samples from the martian meteorite suite [2]. The mesostasis of MIL 03346 contains skeletal titanomagnetite. Several scientists noticed several years ago (e.g. [8]) that this titanomagnetite contains very fine oxidation-driven exsolution lamellae (Figure 1). However, the lamellae are so small that they cannot be characterized by electron microprobe analysis (EMPA). Here we select several areas for focused ion beam (FIB) extraction, prepare transmission electron microscopy (TEM) foils, and identify and analyze the lamellae using TEM at the Johnson Space Center (JSC). The resulting analyses are combined with previous work on nakhlites to interpret the thermal and oxidation history of this meteorite group.

    The storage stability of enrobed goat meat bites (EGMB) incorporated with 3 % crude aloe vera (AV) gel was evaluated under aerobic (T-1; unenrobed control product, T-2; enrobed AV treated product) and modified atmospheric packaging (MAP, 50:50, CO2 and N2) (T-3; unenrobed control product, T-4; enrobed AV treated product) at 4 ± 1 °C for 42 days on the basis of physico-chemical, microbiological and sensory attributes. The pH value was higher, whereas water activity (aW) was lower in enrobed and MAP product. Thiobarbituric acid reacting substances (TBARS) and free fatty acid (FFA) values were significantly (P Standard Plate Count (SPC) was significantly (P < 0.05) lower in MAP products than aerobic packaged products. Results concluded that EGMB treated with AV gel can be successfully stored more than 42 days under MAP conditions without affecting its physico-chemical, textural, microbiological and sensory attributes.

    In this work, we present detailed investigations of methanethiol adsorption on a Cu(4 1 0) surface within the framework of the self-consistent first-principles calculations as implemented in the Vienna ab initio simulation package (VASP). In particular, the adsorption sites, the surface coverage rate and electronic properties have been determined and compared to experimental values. The results indicate that the favorable adsorption site in the case of low coverage rate is a bridge on the step followed by the hollow site on the terrace. The adsorption significantly affects the outermost layer of the surface mainly for a higher coverage rate in a (2 × 2) supercell. The nature of the chemisorption process on the surface is analyzed by means of the density of states which, combined with charge density difference and atomic charge calculations, confirms the ionic character of the S-Cu bond. The specific effect of the presence of steps is highlighted by comparing the adsorption on the (1 0 0) terrace to the adsorption on the extended Cu(1 0 0) surface. Compared to the flat Cu(1 0 0), it is found here that while the stability is almost the same at p(2 × 2) coverage, the CH3S/Cu(4 1 0) becomes more stable than CH3S/Cu(1 0 0) at c(2 × 2) coverage with 0.30 eV per molecule. The mechanism of methanethiol dissociation is explored by the nudged elastic band method and demonstrates that the most favorable path is dissociation followed by migration of hydrogen from the step to its most stable position (hollow on the terrace) with energy barriers less than 0.5 eV.

    The present work illustrates the Microwave-Assisted Drying (MWAD) characteristic of aloe vera gel combined with process optimization and artificial neural network modeling. The influence of microwave power (160-480 W), gel quantity (4-8 g) and drying time (1-9 min) on the moisture ratio was investigated. The drying of aloe gel exhibited typical diffusion-controlled characteristics with a predominant interaction between input power and drying time. Falling rate period was observed for the entire MWAD of aloe gel. Face-centered Central Composite Design (FCCD) developed a regression model to evaluate their effects on moisture ratio. The optimal MWAD conditions were established as microwave power of 227.9 W, sample amount of 4.47 g and 5.78 min drying time corresponding to the moisture ratio of 0.15. A computer-stimulated Artificial Neural Network (ANN) model was generated for mapping between process variables and the desired response. `Levenberg-Marquardt Back Propagation' algorithm with 3-5-1 architect gave the best prediction, and it showed a clear superiority over FCCD.

    In the present investigation, the effect of Aloe vera gel powder on angiotensin-converting enzyme (ACE) inhibitory activity, extent of proteolysis during fermentation and survival of Lactobacillus casei NCDC19 during storage of fermented milk was studied. Among the different cultures screened for ACE inhibitory activity, Lactobacillus casei NCDC 19 exhibited the highest ACE inhibition (approx. 40%) as well as extent of proteolysis (0.37, Abs₃₄₀). In the presence of Aloe vera (0.5% and 1% w/v) an increase in extent of proteolysis (0.460 ± 0.047 and 0.480 ± 0.027) and percent ACE inhibitory activity (44.32 ± 2.83 and 47.52 ± 1.83) was observed in comparison to control. Aloe vera powder addition also led to an increase in viable counts (>11 log cfu mL⁻¹) of L. casei NCDC 19 in fermented milk during storage for 7 days and the counts were maintained in sufficiently higher numbers. The study suggests Aloe vera to be a good functional ingredient which can be further explored for different health attributes. © 2014 Society of Chemical Industry.
