DA1 receptors modulation in rat isolated trachea.
Cabezas, Gloria A; Velasco, Manuel
2010-01-01
We have previously demonstrated that low dose of inhaled dopamine (0.5-2 microg kg(-1) min(-1)) induces broncodilatacion in patients with acute asthma attack, suggesting that this dopamine effect is mediated by dopaminergic rather than by adrenergic receptors. To understand better these dopamine effect, rat tracheal smooth muscle was used as a model to evaluate the responses of beta2-, alpha1-, alpha2-adrenergic and DA1 and DA2 dopaminergic antagonists. Tracheal rings from male Sprague-Dawley rats (n = 90) were excised and placed in an organ bath containing modified Krebs-Ringer bicarbonate buffer at 37 degrees C, and gassed with O2 (95%) and CO2 (5%). Contractile responses were recorded with an isometric transducer in a polygraph (Letica, Spain). Contraction was induced by accumulative doses of acetylcholine (0.1, 0.3, 1, 3, 10 mM) or by electric field stimulation (10 Hz at 2 milliseconds), and accumulative doses of dopamine were added to the bath. Low concentration (0.1-0.3 mM) elicited a small initial contraction, followed by a marked relaxation. Cholinergic contraction was completely reversed at 6 mM of dopamine. This biphasic dopaminergic response was not blocked by incubation with beta2-adrenergic antagonist propranolol (0.1 microM), alpha1-antagonist, terazosin (0.1 mM), alpha2-antagonist, yohimbine (0.1 mM), or by DA2 antagonist metoclopramide (1-8 mM); DA1 antagonist SCH23390 (0.1 microM) produced a sustained increase of basal tone but did not block initial dopaminergic contraction and partially inhibited bronchodilator effect of dopamine. Dopaminergic relaxation in rat trachea is mediated by DA1 rather than by DA2 receptors; and adrenergic receptors are not involved in such dopamine-induced response. Finally, DA1 antagonist SCH23390 exerts intrinsic contractile activity on airway smooth muscle that deserves further research.

Full Text Available The present study emphasizes the biosurfactant mediated anthracene degradation by a marine alkaliphile Bacillus licheniformis (MTCC 5514. The isolate, MTCC 5514 degraded >95% of 300 ppm anthracene in an aqueous medium within 22 days and the degradation percentage reduced significantly when the concentration of anthracene increased to above 500 ppm. Naphthalene, naphthalene 2-methyl, phthalic acid and benzene acetic acid are the products of degradation identified based on thin layer chromatography, high performance liquid chromatography, gas chromatography and mass analyses. It has been observed that the degradation is initiated by the biosurfactant of the isolate for solubilization through micellation and then the alkali pH and intra/extra cellular degradative enzymes accomplish the degradation process. Encoding of genes responsible for biosurfactant production (licA3 as well as catabolic reactions (C23O made with suitable primers designed. The study concludes in situ production of biosurfactant mediates the degradation of anthracene by B. licheniformis.

Full Text Available CONTEXT: Diabetes mellitus is a disease characterized by hyperglycemia that, when allowed to progress long-term untreated, develops vascular and neurological complications, which are responsible for the development of alterations in the enteric nervous system in diabetic patients. In the gastrointestinal tract, diabetes mellitus promotes motor and sensory changes, and in the reflex function of this system, causing gastroparesis, diarrhea, constipation, megacolon, slow gastrointestinal transit, gastric stasis and dilation with decreased or increased peristaltic contractions. Several studies have shown that oxidative stress is the main responsible for the vascular and neurological complications affecting the enteric nervous system of diabetics. OBJECTIVE: The effects of 0.1% and 2% vitamin E on myosin-V- and nNOS-immunoreactive neurons in the jejunum of diabetic rats were investigated. METHODS: Thirty rats were divided into the groups: normoglycemic, normoglycemic treated with 0.1% vitamin E, normoglycemic treated with 2% vitamin E, diabetic, diabetic treated with 0.1% vitamin E, and diabetic treated with 2% vitamin E. The neuronal density and areas of neuron cell bodies were determined. RESULTS: Diabetes (diabetic group significantly reduced the number of myosin-V-immunoreactive neurons compared with the normoglycemic group. The diabetic treated with 0.1% vitamin E and diabetic treated with 2% vitamin E groups did not exhibit a greater density than the D group (P>0.05. Nitrergic density did not change with diabetes (P>0.05. The areas of myosin-V- and nNOS-immunoreactive neurons significantly increased in the normoglycemic treated with 2% vitamin E and diabetic groups compared with the normoglycemic group. CONCLUSION: Supplementation with 2% vitamin E had a neurotrophic effect only in the area of myosin-V-immunoreactive neurons compared with the diabetic group.CONTEXTO: O diabetes mellitus (DM é uma doença caracterizada pela hiperglicemia que a

Microstructural evolution of nanostructured Ti0.9Al0.1N prepared by reactive ball-milling
International Nuclear Information System (INIS)
Bhaskar, U.K.; Bid, S.; Pradhan, S.K.
2011-01-01
Research highlights: → Nanocrystalline stoichiometric Ti 0.9 Al 0.1 N powder has been prepared by ball-milling the 0.9 mol fraction of α-Ti (hcp) and 0.1 mol fraction of aluminum (fcc) powders under N 2 at room temperature. Initially, α-Ti phase partially transformed to the transient β-Ti phase and Ti 0.9 Al 0.1 N (fcc) phase is noticed to form after 3 h of milling. Nanocrystalline stoichiometric Ti 0.9 Al 0.1 N phase is formed after 7 h of milling. The main features which are observed in the present study are stated below: 1.During ball-milling of α-Ti, the α-Ti phase partially converted to transient cubic β-Ti phase within 1 h of milling. 2.Ti 0.9 Al 0.1 N (fcc) phase is noticed to form after 3 h of milling. Complete formation of Ti 0.9 Al 0.1 N (fcc) is obtained at 7 h of milling which is lesser than complete formation time (9 h) of TiN. Doping Al atoms accelerates the formation of (TiAl)N phase. 3.The particle size of Ti 0.9 Al 0.1 N decrease rapidly up to 3 h and then increase slightly due to agglomeration effect. 4.The particle size of Ti 0.9 Al 0.1 N estimated from X-ray is in good agreement with that measured from HRTEM. - Abstract: Nanocrystalline stoichiometric Ti 0.9 Al 0.1 N powder has been prepared by ball-milling the α-Ti (hcp) and aluminum (fcc) powders under N 2 at room temperature. Initially, α-Ti phase partially transformed to the transient cubic β-Ti phase and Ti 0.9 Al 0.1 N (fcc) phase is noticed to form after 3 h of milling. Nanocrystalline stoichiometric Ti 0.9 Al 0.1 N phase is formed after 7 h of milling. After 1 h of milling, all Al atoms are diffused into the α-Ti matrix. The transient β-Ti phase is noticed to form after 1 h of milling and disappears completely after 7 h of milling. Microstructure characterization of unmilled and ball-milled powders by analyzing XRD patterns employing the Rietveld structure refinement reveals the inclusion of Al and nitrogen atoms into the Ti lattice on the way to formation of Ti 0.9 Al 0.1 N

The heavy metal in-taken by plants from contaminated soils is usually assessed by extraction with 0.1N HCl. This study characterized the chemical form of lead in the solid residue of 0.1N HCl-extracted Pb-contaminated kaolin. The results indicate that most lead in the 0.1N HCl-extracted residue of the Pb(NO 3 ) 2 -contaminated kaolin dried at 105 deg C is mainly in form of PbCl 2 . For other lead-containing kaolin sample heated at 900 deg C, the XAS analysis also shows that majority of the lead compound was converted into PbCl 2 precipitate that remained in the solid residue during the 0.1N HCl extraction. Because PbCl 2 is only slightly soluble in dilute acids or water, it is suggested that using 0.1N HCl liquid as an extracting reagent to represent the heavy metal uptake by plants might actually underestimate the uptake

Izmest'ev, A.A.; Pogosyan, G.S.; Sisakyan, A.N.; Winternitz, P.
1998-01-01
Inonu-Wigner contractions from the rotation group O (n + 1) to the Euclidean group E (n) are used to relate the separation of variables in Laplace-Beltrami operators on n-dimensional spheres and Euclidean spaces. We consider all subgroup type coordinates corresponding to different chains of subgroups of O (n + 1) and E (n). In particular, the contractions relate the graphical formalism of 'trees' on spheres to the 'clusters' on Euclidean spaces (introduced in this article). The contractions are considered analytically on several levels: the vector fields realizing the Lie algebras, the complete sets of commuting operators characterizing separable coordinate systems, the coordinate systems themselves and the separated eigenfunctions

O objetivo deste estudo é analisar a cobertura da gripe A(H1N1 2009 pelo Fantástico, conjugando uma análise de conteúdo com uma análise qualitativa sobre a forma como o programa apresentou a doença. Encontramos 16 matérias sobre o tema, veiculadas entre 26 de abril e 16 de agosto de 2009. A maioria teve como frame principal o alastramento da doença, mostrando dados epidemiológicos na forma de numeradores sem denominadores e falando em "alarde", "pânico" e "preocupação". As fontes mais frequentes foram representantes de governo e as vozes mais ouvidas foram cidadãos comuns. Medidas de contenção da gripe foram mencionadas com alta frequencia, com destaque para o uso de máscaras e a higienização das mãos. Também foram frequentes recomendações feitas por médicos e cerca de metade das matérias abordou os sintomas. Nossos resultados indicam que a cobertura do Fantástico optou por manter um tom de preocupação por meio das narrativas compostas e das imagens que acompanharam as matérias feitas sobre a gripe A(H1N1 2009.

Full Text Available We synthesized Mn3Zn0.9Cu0.1N by solid state reaction, and magnetic as well as electrical transport properties were investigated. It is found that Mn3Zn0.9Cu0.1N exhibits a first-order antiferromagnetism (AFM to paramagnetic (PM transition with the Néel temperature TN ~163 K, and substitution of Cu for Zn would favor ferromagnetism (FM state and weaken AFM ground state, leading to a convex curvature character of M(T curve. With high external fields 10 kOe–50 kOe, magnetic transition remains a robust AFM-PM feature while FM phase is completely suppressed. Thermal hysteresis of M(T under 500 Oe is also suppressed when the magnetic field exceeds 10 kOe. Mn3Zn0.9Cu0.1N exhibits a good metallic behavior except for a slope change around TN, which is closely related to AFM-PM magnetic transition. Compared with the first differential of resistivity with respect to temperature for (dρ/dTMn3ZnN in transition temperature range, the absolute value of (dρ/dTMn3Zn0.9Cu0.1N is much lower which is close to zero.
O vírus Influenza H1N1 e os trabalhadores da suinocultura: uma revisão

Neidimila Aparecida Silveira Oliveira
Full Text Available Considerando-se o grande impacto midiático e populacional da recente epidemia pelo vírus Influenza H1N1, em função do seu risco potencial de alta letalidade, decidimos realizar esta revisão, de forma a melhor compreender as relações entre a exposição aos suínos e a possível contaminação laboral. A influenza, também conhecida como gripe, é uma doença viral adquirida através do contato humano com animais domesticados. Os suínos são importantes hospedeiros do vírus Influenza H1N1 (swine-like Influenza A e susceptíveis às infecções por vírus Influenza de origem aviária e humana. Os suínos possuem importante papel na transmissão viral entre espécies e na epidemiologia da influenza humana. A epidemia por Influenza A H1N1/2009 representou um grande desafio para as autoridades públicas e setores privados da saúde, no que se refere às medidas de planejamento e execução de ações de prevenção e tratamento. Estima-se que 89 milhões de pessoas tenham sido contaminadas por este vírus, com até 403 mil casos de hospitalização e 18.300 óbitos até abril de 2010. Embora estejamos em período pós-pandemia, acredita-se que o vírus H1N1 tenha atualmente um comportamento semelhante ao vírus de gripe sazonal, causando focos infecciosos localizados e com níveis ainda significativos de transmissão. Destaca-se a preocupação com a saúde dos trabalhadores diretamente ligados à suinocultura, já que essa atividade produtiva apresenta uma situação de risco aos trabalhadores envolvidos e também à comunidade.

Para minimizar tais casos é importante, dentre outras medidas, a qualificação do trabalhador de saúde. Nesse sentido, o objetivo foi descrever o nível de informação dos profissionais de Enfermagem, de um hospital do interior baiano, sobre a transmissão do vírus da H1N1, sintomatologia e quais os EPIs são necessários na assistência aos pacientes com suspeita ou confirmação diagnóstica. Métodos: Trata-se de um relato de experiência vivenciado por acadêmicos de Enfermagem da Universidade do Estado da Bahia, que desenvolveram atividades do componente curricular Processo do Cuidar: Fundamentação e Prática em um hospital público na Bahia. Os dados do relato são provenientes de coleta realizada junto aos enfermeiros, abordando aspectos da sintomatologia, transmissão e equipamentos de proteção individual. Cada profissional de Enfermagem respondeu espontaneamente as perguntas e ao final foi discutido cada item visando sanar dúvidas, promovendo, desse modo, uma atividade educativa baseada nos conhecimentos dos profissionais. Resultados: Embora a maioria dos participantes reconhecesse os equipamentos de proteção individual e a sintomatologia da doença viral, alguns ainda desconhecem as vias de transmissão. A maioria não recebeu nenhuma capacitação sobre a temática. Conclusão: É necessário implantar um Núcleo de Educação Permanente para sanar dúvidas sobre esta e outras temáticas, mas que não se limitem a ações pontuais e que busquem parcerias com as instituições de ensino superior. DESCRITORES: Educação continuada. Educação em Enfermagem. Transmissão de doença infecciosa. Controle de doenças transmissíveis.

The aim of this study was to assess the results of curative surgery with and without radiotherapy in patients with T 1-2 N 0-1 oral tongue squamous cell carcinoma (OSCC) and to evaluate survival and prognostic factors. Retrospective analysis of 86 patients with T 1-2 N 0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3%) received postoperative radiotherapy (PORT). Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. The median follow-up was 45 months. The five-year overall survival (OS) and disease-free survival (DFS) rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth). In the risk group, there was no local failure in patients with postoperative radiotherapy. In T 1-2 N 0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features

2014-09-15
Optical materials composed of La{sub 1−m−n}Er{sub m}Yb{sub n}OCl (m=0.001–0.2, n=0–0.1) solid solution were prepared via a solid-state reaction using excess NH{sub 4}Cl flux at 950 °C for 30 min. X-ray diffraction patterns of La{sub 1−m}Er{sub m}OCl were compared upon altering the molar ratios of the flux to the La{sup 3+} (Er{sup 3+}, Yb{sup 3+}) ions. By means of photoluminescence spectra, the dependence of the luminescence intensity as a function of the Er{sup 3+} content and the color CIE coordinates of the Er{sup 3+}-doped layered LaOCl compounds were also investigated under excitation by near-ultraviolet (NUV) and visible light. The spectral conversion properties of Er{sup 3+} and Er{sup 3+}–Yb{sup 3+} ions doped into LaOCl phosphors were elucidated under diode-laser irradiation of 980 nm in wavelength. The desired up-conversion of the emitting light, passing throughout the green, orange, and red regions of the spectrum, was achieved by appropriate Er{sup 3+} and/or Yb{sup 3+} concentrations in the LaOCl host structure under 980-nm-excitation light, while its mechanism in the phosphors was described by an energy-level schematic. Up-conversion emission spectra and the dependence of the emission intensity on pump power in the La{sub 0.89}Er{sub 0.1}Yb{sub 0.01}OCl phosphor were investigated under diode-laser irradiation of both wavelengths, 980 and 1550 nm. - Highlights: • Flux-assisted La{sub 1−m−n}Er{sub m}Yb{sub n}OCl (m=0.001–0.2, n=0–0.1) phosphors were prepared. • Distinctive photoluminescence properties of Er{sup 3+}-doped LaOCl were investigated. • Spectral converting properties of Er{sup 3+} and Yb{sup 3+} in LaOCl phosphors were elucidated. • Up-conversion mechanisms are proposed on the basis of an energy-level diagram. • Dependence of the emission intensity on pump power in the phosphor was investigated.

This study investigated if prior eccentric contractions, and thus mechanical strain and muscle damage, exert an effect on the muscle membrane phospholipid fatty acid composition in rats, and whether a possible effect could be attenuated by dietary supplements. Twenty-three rats were randomised...... muscle, was excised from both legs. In the muscles stimulated to contract eccentrically, compared to the control muscles, the proportion of arachidonic acid, C20:4,n-6 (17.7 +/- 0.6; 16.4 +/- 0.4% of total fatty acids, respectively) and docosapentanoeic acid, C22:5,n-3 (2.9 +/- 0.1 and 2.7 +/- 0.......1% of total fatty acids, respectively) was uniformly higher across groups (P fatty acids) compared to the control leg (38.2 +/- 0...

In skeletal muscle, the actin cytoskeleton-regulating GTPase, Rac1, is necessary for insulin-dependent GLUT4 translocation. Muscle contraction increases glucose transport and represents an alternative signaling pathway to insulin. Whether Rac1 is activated by muscle contraction and regulates contraction-induced glucose uptake is unknown. Therefore, we studied the effects of in vivo exercise and ex vivo muscle contractions on Rac1 signaling and its regulatory role in glucose uptake in mice and humans. Muscle Rac1-GTP binding was increased after exercise in mice (~60-100%) and humans (~40%), and this activation was AMP-activated protein kinase independent. Rac1 inhibition reduced contraction-stimulated glucose uptake in mouse muscle by 55% in soleus and by 20-58% in extensor digitorum longus (EDL; P contraction-stimulated increment in glucose uptake was decreased by 27% (P = 0.1) and 40% (P muscles, respectively, of muscle-specific inducible Rac1 knockout mice. Furthermore, depolymerization of the actin cytoskeleton decreased contraction-stimulated glucose uptake by 100% and 62% (P muscles, respectively. These are the first data to show that Rac1 is activated during muscle contraction in murine and human skeletal muscle and suggest that Rac1 and possibly the actin cytoskeleton are novel regulators of contraction-stimulated glucose uptake.

nth roots of normal contractions
International Nuclear Information System (INIS)
Duggal, B.P.
1992-07-01
Given a complex separable Hilbert space H and a contraction A on H such that A n , n≥2 some integer, is normal it is shown that if the defect operator D A = (1 - A * A) 1/2 is of the Hilbert-Schmidt class, then A is similar to a normal contraction, either A or A 2 is normal, and if A 2 is normal (but A is not) then there is a normal contraction N and a positive definite contraction P of trace class such that parallel to A - N parallel to 1 = 1/2 parallel to P + P parallel to 1 (where parallel to · parallel to 1 denotes the trace norm). If T is a compact contraction such that its characteristics function admits a scalar factor, if T = A n for some integer n≥2 and contraction A with simple eigen-values, and if both T and A satisfy a ''reductive property'', then A is a compact normal contraction.

We present a statistical survey of the energy spectrum of solar wind suprathermal (∼0.1–1.5 keV) electrons measured by the WIND 3DP instrument at 1 AU during quiet times at the minimum and maximum of solar cycles 23 and 24. After separating (beaming) strahl electrons from (isotropic) halo electrons according to their different behaviors in the angular distribution, we fit the observed energy spectrum of both strahl and halo electrons at ∼0.1–1.5 keV to a Kappa distribution function with an index κ and effective temperature T{sub eff}. We also calculate the number density n and average energy E{sub avg} of strahl and halo electrons by integrating the electron measurements between ∼0.1 and 1.5 keV. We find a strong positive correlation between κ and T{sub eff} for both strahl and halo electrons, and a strong positive correlation between the strahl n and halo n, likely reflecting the nature of the generation of these suprathermal electrons. In both solar cycles, κ is larger at solar minimum than at solar maximum for both strahl and halo electrons. The halo κ is generally smaller than the strahl κ (except during the solar minimum of cycle 23). The strahl n is larger at solar maximum, but the halo n shows no difference between solar minimum and maximum. Both the strahl n and halo n have no clear association with the solar wind core population, but the density ratio between the strahl and halo roughly anti-correlates (correlates) with the solar wind density (velocity)

Complex numbers in n dimensions
Olariu, Silviu
2002-01-01
Two distinct systems of hypercomplex numbers in n dimensions are introduced in this book, for which the multiplication is associative and commutative, and which are rich enough in properties such that exponential and trigonometric forms exist and the concepts of analytic n-complex function, contour integration and residue can be defined. The first type of hypercomplex numbers, called polar hypercomplex numbers, is characterized by the presence in an even number of dimensions greater or equal to 4 of two polar axes, and by the presence in an odd number of dimensions of one polar axis. The other type of hypercomplex numbers exists as a distinct entity only when the number of dimensions n of the space is even, and since the position of a point is specified with the aid of n/2-1 planar angles, these numbers have been called planar hypercomplex numbers. The development of the concept of analytic functions of hypercomplex variables was rendered possible by the existence of an exponential form of the n-complex numbe...

A projective geometry argument is also presented with disclosure of the occurrence a group contraction mechanism as a geometric consequence of spontaneous breakdown of symmetry. It is also shown that a contraction of the conformal group gives account of the number of degrees of freedom of an n-pseudoparticle system in an Euclidean SU(2) gauge invariant Yang-Mills theory, in agreement with the result obtained by algebraic geometry methods. Low-energy theorems and ordered states symmetry patterns are observable manifestations of group contractions. These results seem to support the conjecture that the transition from quantum to classical physics involves a group contraction mechanism. (author)

1 / n Expansion for the Number of Matchings on Regular Graphs and Monomer-Dimer Entropy
Pernici, Mario
2017-08-01
Using a 1 / n expansion, that is an expansion in descending powers of n, for the number of matchings in regular graphs with 2 n vertices, we study the monomer-dimer entropy for two classes of graphs. We study the difference between the extensive monomer-dimer entropy of a random r-regular graph G (bipartite or not) with 2 n vertices and the average extensive entropy of r-regular graphs with 2 n vertices, in the limit n → ∞. We find a series expansion for it in the numbers of cycles; with probability 1 it converges for dimer density p diverges as |ln(1-p)| for p → 1. In the case of regular lattices, we similarly expand the difference between the specific monomer-dimer entropy on a lattice and the one on the Bethe lattice; we write down its Taylor expansion in powers of p through the order 10, expressed in terms of the number of totally reducible walks which are not tree-like. We prove through order 6 that its expansion coefficients in powers of p are non-negative.

Full Text Available BACKGROUND: In postmenopausal women there is a rapid destruction of dermal collagen, resulting in accelerated skin ageing, which is manifested by cutaneous atrophy, increased number and depth of wrinkles and sagging. This accelerated catabolism of the collagen is due to estrogen deficiency and increased synthesis of the metalloproteinase-1 enzyme, which degrades the dermal collagen. OBJECTIVES: To assess whether the use of topical estradiol 0.05% cream on photo exposed skin can inhibit the expression of the metalloproteinase-1 enzyme on the dermis and subsequently the rapid loss of collagen in women after menopause. METHODS: We included 40 postmenopausal women without hormone replacement therapy. Information about lifestyle, lipid profile, blood glucose level, thyroid hormones, mammography, Pap smear and transvaginal ultrasound were obtained to rule out associated diseases. Skin biopsy of the right preauricular region was performed before and after treatment with topical estradiol 0.05% for 30 days. The biopsy specimens were subjected to immunohistochemistry to identify the expression of the metalloproteinase-1 enzyme. RESULTS: There was no statistically significant difference on the expression of the metalloproteinase-1 enzyme in keratinocytes, fibroblasts and endothelial cells before and after treatment with topical estradiol for 30 days. CONCLUSION: Treatment with estradiol 0.05% cream, in photo exposed skin for 30 days, does not inhibit the production of metalloproteinase-1.FUNDAMENTOS: Na pós-menopausa, ocorre rápida destruição do colágeno dérmico, com consequente envelhecimento acelerado da pele, que se expressa com atrofia cutânea, aumento do número e da profundidade das rugas e flacidez. Esse catabolismo acelerado do colágeno ocorre por deficiência estrogênica e aumento na síntese da enzima metaloproteinase-1, que degrada o colágeno dérmico. OBJETIVOS: Avaliar se o uso de estradiol tópico a 0,05% em creme na pele

We evaluated the prognostic accuracy of LN variables (N0/N1), numbers of positive lymph nodes (PLN), and lymph node ratio (LNR) in the context of the total number of examined lymph nodes (ELN). Patients from SEER and a single institution (MGH) were reviewed and survival analyses performed in subgroups based on numbers of ELN to calculate excess risk of death (hazard ratio, HR). In SEER and MGH, higher numbers of ELN improved the overall survival for N0 patients. The prognostic significance (N0/N1) and PLN were too variable as the importance of a single PLN depended on the total number of LN dissected. LNR consistently correlated with survival once a certain number of lymph nodes were dissected (≥13 in SEER and ≥17 in the MGH dataset). Better survival for N0 patients with increasing ELN likely represents improved staging. PLN have some predictive value but the ELN strongly influence their impact on survival, suggesting the need for a ratio-based classification. LNR strongly correlates with outcome provided that a certain number of lymph nodes is evaluated, suggesting that the prognostic accuracy of any LN variable depends on the total number of ELN.

Full Text Available RESUMOO mercado de milho possui importante participação no cenário agropecuário nacional, pela relevância dentro da indústria de carnes. Destacam-se as estratégias de comercialização do grão, em especial as relacionadas à mitigação do risco de preço com o uso de contratos futuros. Objetiva-se identificar e interpretar os efeitos causados pela modificação no contrato futuro do milho negociado na BM&F-Bovespa, que em setembro de 2008 passou de entrega física para liquidação financeira, sobre o desempenho do mercado futuro do grão comercializado. Avaliam-se a liquidez dos contratos, a volatilidade dos preços futuro e físico do milho, bem como a convergência da base. Identificaram-se como possíveis efeitos da alteração contratual o aumento da liquidez do contrato futuro de milho e a redução da volatilidade dos preços, além da melhoria na convergência da base. Os resultados alinham-se com a teoria e evidenciam impacto positivo da implementação da liquidação financeira no contrato futuro de milho.ABSTRACTThe corn market plays an important role in the national agricultural scenario, given its relevance in the meat industry, where grain marketing strategies are outstanding, especially those related to price risk mitigation using futures contracts. This article aims to identify and interpret the effects of the changes of the corn futures contract traded at the BM&F-Bovespa, which shifted in September 2008 from physical delivery to cash settlement, on the grain futures market performance. We evaluated contract liquidity, volatility of future and physical corn prices, and base convergence. The possible effects of the contract amendment include the increase in liquidity of the corn futures contract, reduction of the price volatility and improved base convergence. The results are in line with the theory and highlight the positive impact of implementing cash settlement for corn futures.RESUMENEl mercado del maíz tiene un

We present a generalization of the standard Inoenue-Wigner contraction by rescaling not only the generators of a Lie superalgebra but also the arbitrary constants appearing in the components of the invariant tensor. The procedure presented here allows one to obtain explicitly the Chern-Simons supergravity action of a contracted superalgebra. In particular we show that the Poincare limit can be performed to a D = 2 + 1 (p,q) AdS Chern-Simons supergravity in presence of the exotic form. We also construct a new three-dimensional (2,0) Maxwell Chern-Simons supergravity theory as a particular limit of (2,0) AdS-Lorentz supergravity theory. The generalization for N = p + q gravitinos is also considered. (orig.)

We compared changes in markers of muscle damage and systemic inflammation after submaximal and maximal lengthening muscle contractions of the elbow flexors. Using a cross-over design, 10 healthy young men not involved in resistance training completed a submaximal trial (10 sets of 60 lengthening contractions at 10% maximum isometric strength, 1 min rest between sets), followed by a maximal trial (10 sets of three lengthening contractions at 100% maximum isometric strength, 3 min rest between sets). Lengthening contractions were performed on an isokinetic dynamometer. Opposite arms were used for the submaximal and maximal trials, and the trials were separated by a minimum of two weeks. Blood was sampled before, immediately after, 1 h, 3 h, and 1-4 d after each trial. Total leukocyte and neutrophil numbers, and the serum concentration of soluble tumor necrosis factor-alpha receptor 1 were elevated after both trials (P < 0.01), but there were no differences between the trials. Serum IL-6 concentration was elevated 3 h after the submaximal contractions (P < 0.01). The concentrations of serum tumor necrosis factor-alpha, IL-1 receptor antagonist, IL-10, granulocyte-colony stimulating factor and plasma C-reactive protein remained unchanged following both trials. Maximum isometric strength and range of motion decreased significantly (P < 0.001) after both trials, and were lower from 1-4 days after the maximal contractions compared to the submaximal contractions. Plasma myoglobin concentration and creatine kinase activity, muscle soreness and upper arm circumference all increased after both trials (P < 0.01), but were not significantly different between the trials. Therefore, there were no differences in markers of systemic inflammation, despite evidence of greater muscle damage following maximal versus submaximal lengthening contractions of the elbow flexors.

Full Text Available A infecção causada pelo vírus Influenza A (IAV é endêmica em suínos no mundo inteiro. O surgimento da pandemia de influenza humana pelo vírus A/H1N1 (pH1N1 em 2009 levantou dúvidas sobre a ocorrência deste vírus em suínos no Brasil. Durante o desenvolvimento de um projeto de pesquisa do vírus de influenza suína em 2009-2010, na Embrapa Suínos e Aves (CNPSA, foi detectado em um rebanho de suínos em Santa Catarina, Brasil, um surto de influenza altamente transmissível causado pelo subtipo viral H1N1. Este vírus causou uma doença leve em suínos em crescimento e em fêmeas adultas, sem mortalidade. Tres leitões clinicamente afetados foram eutanasiados. As lesões macroscópicas incluiam consolidação leve a moderada das áreas cranioventrais do pulmão. Microscopicamente, as lesões foram caracterizadas por bronquiolite necrosante obliterativa e pneumonia broncointersticial. A imunohistoquímica, utilizando um anticorpo monoclonal contra a nucleoproteína do vírus influenza A, revelou marcação positiva no núcleo das células epiteliais bronquiolares. O tecido pulmonar de três leitões e os suabes nasais de cinco fêmeas e quatro leitões foram positivos para influenza A pela RT-PCR. O vírus influenza foi isolado de um pulmão, mais tarde sendo confirmado pelo teste de hemaglutinação (título HA 1:128 e por RT-PCR. A análise das seqüências de nucleotídeos dos genes da hemaglutinina (HA e proteína da matriz (M revelou que o vírus isolado foi consistente com o vírus pandêmico A/H1N1/2009 que circulou em humanos no mesmo período. Este é o primeiro relato de um surto de influenza causado pelo vírus pandêmico A/H1N1 em suínos no Brasil.

Full Text Available A utilização de leguminosas é um método visado para a recuperação de fertilidade dos solos, visto que além de fornecerem matéria orgânica também fixam nitrogênio ao solo. Por isso, mostram-se relevantes pesquisas acerca da capacidade das leguminosas para utilização em solos salinos com o intuito de se auxiliar a recuperação destes. Dessa forma, este trabalho teve como objetivo avaliar a influência da salinidade na germinação, no desenvolvimento e no isolamento de microrganismos endofíticos da leguminosa mucuna preta (Mucuna aterrima. O experimento foi realizado com tratamentos de NaCl, em delineamento inteiramente casualizado (5x3 com cinco tratamentos (0,0; 0,025; 0,05; 0,1; 0,2 mol NaCl/L e três repetições. Foram analisados a porcentagem de germinação, a massa seca da raiz, caule e folhas e efetuada a contagem de bactérias e fungos endofíticos. Como resultado, verificou-se uma redução da porcentagem da taxa de germinação com o aumento da salinidade. Apesar de não ser observada interferência na riqueza de microrganismos, verificou-se maior resistência das bactérias à salinidade. Dessa forma, este estudo indica que a mucuna preta não é indicada para plantio em solos com concentrações salinas maiores que 0,1 mol NaCL/L, pois essa concentração apresenta toxicidade para a planta e não favorece sua germinação.

Tests have been made in the Langley 4- by 4-foot supersonic pressure tunnel at Mach numbers of 1.41, 1.61, and 2.01 to determine the static longitudinal stability and control characteristics of various arrangements of the Grumman F11F-1 airplane. Tests were made of the complete model and various combinations of its component parts and, in addition, the effects of various body modifications, a revised vertical tail, and wing fences on the longitudinal characteristics were determined. The results indicate that for a horizontal-tail incidence of -10 deg the trim lift coefficient varied from 0.29 at a Mach number of 1.61 to 0.23 at a Mach number of 2.01 with a corresponding decrease in lift-drag trim from 3.72 to 3.15. Stick-position instability was indicated in the low-supersonic-speed range. A photographic-type nose modification resulted in slightly higher values of minimum drag coefficient but did not significantly affect the static stability or lift-curve slope. The minimum drag coefficient for the complete model with the production nose remained essentially constant at 0.047 throughout the Mach number range investigated.

The effects of continuous but asynchronous nerve activity induced by ciguatoxin (CTX-1) on the membrane potential and contraction of smooth muscle cells have been investigated in rat proximal tail arteries isolated in vitro. These effects have been compared with those produced by the continuous application of phenylephrine (PE).CTX-1 (0.4 nM) and PE (10 μM) produced a maintained depolarization of the arterial smooth muscle that was almost completely blocked by α-adrenoceptor blockade. In both cases, the depolarization was more sensitive to the selective α2-adrenoceptor antagonist, idazoxan (0.1 μM), than to the selective α1-adrenoceptor antagonist, prazosin (0.01 μM).In contrast, the maintained contraction of the tail artery induced by CTX-1 (0.2 nM) and PE (2 and 10 μM) was more sensitive to prazosin (0.01) μM, than to idazoxan (0.01 μM). In combination, these antagonists almost completely inhibited contraction to both agents.Application of the calcium channel antagonist, nifedipine (1 μM), had no effect on the depolarization induced by either CTX-1 or PE but maximally reduced the force of the maintained contraction to both agents by about 50%.We conclude that the constriction of the tail artery induced by CTX-1, which mimics the natural discharge of postganglionic perivascular axons, is due almost entirely to α-adrenoceptor activation. The results indicate that neuronally released noradrenaline activates more than one α-adrenoceptor subtype. The depolarization is dependent primarily on α2-adrenoceptor activation whereas the contraction is dependent primarily on α1-adrenoceptor activation. The links between α-adrenoceptor activation and the voltage-dependent and voltage-independent mechanisms that deliver Ca2+ to the contractile apparatus appear to be complex. PMID:9113373

Resistance training with eccentric contraction has been shown to augment muscle hypertrophy more than other contraction modes do (i.e., concentric and isometric contraction). However, the molecular mechanisms involved remain unclear. The purpose of this study was to investigate the effect of muscle contraction mode on mammalian target of rapamycin complex 1 (mTORC1) signaling using a standardized force-time integral (load (weight) × contraction time). Male Sprague-Dawley rats were randomly assigned to three groups: eccentric contraction, concentric contraction, and isometric contraction. The right gastrocnemius muscle was exercised via percutaneous electrical stimulation-induced maximal contraction. In experiment 1, different modes of muscle contraction were exerted using the same number of reps in all groups, while in experiment 2, muscle contractions were exerted using a standardized force-time integral. Muscle samples were obtained immediately and 3 h after exercise. Phosphorylation of molecules associated with mTORC1 activity was assessed using western blot analysis. In experiment 1, the force-time integral was significantly different among contraction modes with a higher force-time integral for eccentric contraction compared to that for other contraction modes (P contraction compared to that for isometric contraction (P contraction than for other modes of contraction (P contraction was higher than isometric contraction (P contraction modes 3 h after exercise. Our results suggest that mTORC1 activity is not determined by differences in muscle contraction mode itself. Instead, mTORC1 activity is determined by differences in the force-time integral during muscle contraction. © 2016 The Authors.

Full Text Available Objetivou-se, neste trabalho, estudar o efeito do beneficiamento sobre o conteúdo de impurezas, pó e o número de neps na pluma, em 12 algodoeiras do Estado de Mato Grosso. O experimento consistiu de uma combinação fatorial de cinco etapas de beneficiamento do algodão em 12 algodoeiras em delineamento inteiramente casualizado com quatro repetições. Amostras de algodão foram coletadas nas seguintes etapas: a no desmanche do fardão; b antes do descaroçamento; c logo após o descaroçamento; d na bica, sem o uso do limpador tipo serrilha; e na bica, após a limpeza da pluma, utilizando-se o limpador tipo serrilha. Em todas as etapas se retiraram quatro amostras padrão de pluma com massa de 350 g a fim de serem analisadas mediante o instrumento AFIS (Advanced Fiber Information System para determinação do conteúdo de impurezas e poeira e o número de neps da fibra. Os resultados indicam que os processos de prelimpeza do algodão em caroço e limpeza da pluma reduzem o conteúdo de impurezas e da poeira do algodão enquanto, juntamente com o descaroçamento, esses processos aumentaram o número de neps da fibra do algodão. A utilização do limpador de pluma tipo serrilha com manta contínua aumenta a eficiência de limpeza da pluma, porém ocasiona incrementos significativos no número de neps.The purpose of this work was to study the ginning effect on the amount of cotton contaminants, dust and neps in cotton fiber, in 12 industries in the Mato Grosso State.

Full Text Available O Syzygium cumini, também conhecido como Jambolão é amplamente utilizado na medicina popular para o tratamento da diabetes melito. Este estudo verificou a eficiência do extrato da casca de Syzygium cumini sobre os níveis glicêmicos e estresse oxidativo de ratos normais e diabéticos induzidos por aloxano. Os animais foram divididos em grupo controle (C, controle tratado (CT, diabético controle (DC e diabético tratado (DT. A administração oral do extrato aquoso da casca de Jambolão, na dose de 1g/kg de peso vivo, por um período de trinta dias, não resultou em uma redução significativa na glicemia e nos níveis de hemoglobina glicosilada. Neste estudo, o tratamento com o extrato demonstrou um aumento dos níveis de substâncias reativas ao ácido tiobarbitúrico (TBA-RS no plasma dos ratos do grupo DT (P<0,05, comparado com o C. A atividade da catalase nos rins dos ratos do grupo DC diminuiu significativamente (P<0,01 e no fígado houve uma elevação significativa dessa enzima no grupo DC (P<0,01. Estes resultados indicam que o extrato da casca do Jambolão não possui efeito hipoglicemiante em ratos diabéticos induzidos pelo aloxano. O efeito antioxidante desta planta não foi suficiente para diminuir significativamente a produção de TBA-RS. A diminuição da atividade da catalase nos rins pode ser devida à exaustão ou inibição desta enzima e seu aumento, no fígado, devido ao estresse oxidativo, ocasionado pelo estado diabético.

Understanding why the quit rate among smokers of menthol cigarettes is lower than non-menthol smokers requires identifying the neurons that are altered by nicotine, menthol, and acetylcholine. Dopaminergic (DA) neurons in the ventral tegmental area (VTA) mediate the positive reinforcing effects of nicotine. Using mouse models, we show that menthol enhances nicotine-induced changes in nicotinic acetylcholine receptors (nAChRs) expressed on midbrain DA neurons. Menthol plus nicotine upregulates nAChR number and function on midbrain DA neurons more than nicotine alone. Menthol also enhances nicotine-induced changes in DA neuron excitability. In a conditioned place preference (CPP) assay, we observed that menthol plus nicotine produces greater reward-related behavior than nicotine alone. Our results connect changes in midbrain DA neurons to menthol-induced enhancements of nicotine reward-related behavior and may help explain how smokers of menthol cigarettes exhibit reduced cessation rates.

Conclui-se, portanto, que se os resultados obtidos forem decorrentes de alterações provocadas pelo rápido metabolismo da catarata diabética e pela cronicidade da catarata hipermadura sugere-se que o comprometimento da estrutura capsular seja de intensidade equivalente e, por consequência, que isto também possa prejudicar o metabolismo das células do epitélio anterior da lente, diminuindo assim a incidência da opacidade da cápsula posterior de cães com catarata diabética e hipermadura submetidos à facoemulsificação.

We present a projected [ 1 H, 15 N]-HMQC-[ 1 H, 1 H]-NOESY experiment for observation of NOE interactions between amide protons with degenerate 15 N chemical shifts in large molecular systems. The projection is achieved by simultaneous evolution of the multiple quantum coherence of the nitrogen spin and the attached proton spin. In this way NOE signals can be separated from direct-correlation peaks also in spectra with low resolution by fully exploiting both 1 H and 15 N frequency differences, such that sensitivity can be increased by using short maximum evolution times. The sensitivity of the experiment is not dependent on the projection angle for projections up to 45 deg. and no additional pulses or delays are required as compared to the conventional 2D [ 1 H, 15 N]-HMQC-NOESY. The experiment provides two distinct 2D spectra corresponding to the positive and negative angle projections, respectively. With a linear combination of 1D cross-sections from the two projections the unavoidable sensitivity loss in projection spectra can be compensated for each particular NOE interaction. We demonstrate the application of the novel projection experiment for the observation of an NOE interaction between two sequential glycines with degenerate 15 N chemical shifts in a 121.3 kDa complex of the linker H1 histone protein with a 152 bp linear DNA

Full Text Available Algumas publicações relatam que o adensamento populacional dos bananais reduz a severidade da sigatoka-negra (Mycosphaerella fijiensis. Instalou-se um ensaio com cinco tratamentos e quatro repetições. Os tratamentos 1.600, 2.000, 2.400, 2.800 e 3.200 plantas.ha-1 da cultivar D'Angola foram instalados em parcelas agrupadas de 2.000 m² cada. O tamanho das parcelas foi fixo e o número de plantas por parcela variou conforme o espaçamento adotado para cada população. A área de 2.000 m² foi dividida em quatro subáreas de 500 m², considerando-as como parcelas. Em cada subárea selecionaram-se 15 plantas centrais para serem avaliadas. Na época do florescimento registraram-se a severidade da doença na folha n.°10 e o número de folhas viáveis. Na colheita, a altura e o diâmetro do pseudocaule e o peso dos cachos, das pencas e dos frutos. A análise conjunta dos dados indica que todos os tratamentos foram semelhantes entre si e que o adensamento das plantas não controlou a sigatoka-negra.Many publications show that plantations of high density of bananas decrease the severity of black-sigatoka (Mycosphaerella fijiensis. To test this hypothesis it was instaled an experiment with five treatments and four repetitions. The treatments were density plant of 1.600, 2.000, 2.400, 2.800 e 3.200 plant.ha-1. The cultivar planted was D'Angola and each plot had fixed 2.000 m², the number of plants in each plot changed in accordance with the treatment tested. The plots were divided in four subplots of 500 m² where 15 plants located in the center were measured. The evaluation of severity was carried out in the leaf number ten during the flowering period. It was also evaluated the numbers of viable leaves, height, diameter and weight of production (banch, bunches and fruits. The analyses did not show effect of high density in the parameter measured and it was conclued that the treatments tested had not control black-sigatoka.

Os parâmetros envolveram o índice de fêmeas (IF obtido na avaliação de 176 linhagens F6 de soja quanto à resistência ao NCS. Avaliaram-se os genótipos quanto à resposta ao NCS em casa de vegetação e calcularam-se as médias dos IF dos genótipos avaliados. Posteriormente, foram realizadas a distribuição de freqüência e a análise de variância e, então, estimado o número de locos segregantes envolvidos na resistência das linhagens ao NCS (raça 1. Estimou-se o progresso de seleção (i = -2,154 entre as linhagens avaliadas (com diferentes números de repetições, bem como a herdabilidade em nível de média (h². Assim conclui-se que: a A distribuição de normalidade das médias dos IF, bem como a estimativa da herdabilidade e a estimativa do número de locos segregantes indicam que a resposta das linhagens ao NCS (raça 1 tem caráter de herança poligênica; b Foram encontradas linhagens promissoras para resistência ao NCS, porém, como este é de difícil avaliação recomenda-se utilizar maior número de linhagens F6 na avaliação fenotípica e maior número de repetições para avaliação da reação ao NCS; c A necessidade de se fazer correção para efeitos macroambientais aumentou o erro das estimativas.This study aimed at verify the behavior of Recombinant Inbreed Lines, resulting of a cross between Hartwig (resistant parental and EMGOPA-316 (susceptible parental to NCS soybean nematode (race 1 and to estimate genetic parameters and those of selection progress.

Métodos: estudo prospectivo de 19 olhos de 13 pacientes, de 12 a 50 anos (média de 33,77 ± 11,43, submetidos à Tro-Trec e seguidos por 21,6 ± 7,2 (5,1 a 29,7 meses. Resultados: A pressão intraocular, (PIO média inicial de 32,03 ± 10,01 mmHg (variando de 12 a 50, foi reduzida para 9,42 mmHg ± 3,50 (2 e 16, com redução da medicação tópica de 1,47 ± 1,54 (0 a 4 para 0,16 ± 0,37 (0 a 1 medicamentos. A PIO alvo foi atingida em 15 (78,94% olhos. Houve acentuada redução da PIO mesmo em olhos sem bolhas significativas. O procedimento resultou em hipotonia persistente em três olhos. Conclusão: A cirurgia proposta foi eficaz. A acentuada redução da PIO em olhos sem bolhas significativas sugere que, na faixa etária analisada, a trabeculotomia isolada pode ser suficiente para controle da PIO em alguns pacientes. A incidência de hipotonia foi significativa, porém não superior à relacionada à trabeculectomia isolada, para a mesma faixa etária.Purpose: To evaluate the results of the trabeculotomy-trabeculectomy combined procedure in 12 to 50 years old patients with moderate and advanced glaucoma. Methods: Nineteen eyes of thirteen patients underwent a trabeculotomy-trabeculectomy procedure and were prospectively analyzed and followed up for 21,6 ± 7,2 (5,1 a 29,7 months.

This was a community-based study with a random cluster area sample of the inhabitants from the city of Salvador, capital of the State of Bahia. The study population included all individuals from 18 to 65 years of age who reported having a paid job (n = 2,947. Data were obtained through individual household interviews. The overall estimated annual incidence rate was 5.80%, with a non-statistically significant

Celiac disease is associated with the HLA-DR3-DQA1*05:01-DQB1*02:01 and DR4-DQA1*03:01-DQB1*03:02 haplotypes. In addition, there are currently over 40 non-HLA loci associated with celiac disease. This study extends previous analyses on different HLA haplotypes in celiac disease using next generation targeted sequencing. Included were 143 patients with celiac disease and 135 non-celiac disease controls investigated at median 9.8 years (1.4-18.3 years). PCR-based amplification of HLA and sequencing with Illumina MiSeq technology were used for extended sequencing of the HLA class II haplotypes HLA-DRB1, DRB3, DRB4, DRB5, DQA1 and DQB1, respectively. Odds ratios were computed marginally for every allele and haplotype as the ratio of allelic frequency in patients and controls as ratio of exposure rates (RR), when comparing a null reference with equal exposure rates in cases and controls. Among the extended HLA haplotypes, the strongest risk haplotype for celiac disease was shown for DRB3*01:01:02 in linkage with DQA1*05:01-DQB1*02:01 (RR = 6.34; P-value celiac disease among non-Scandinavians (RR = 7.94; P = .011). The data also revealed 2 distinct celiac disease risk DR3-DQA1*05:01-DQB*02:01 haplotypes distinguished by either the DRB3*01:01:02 or DRB3*02:02:01 alleles, indicating that different DRB1*03:01-DQB1*02:01 haplotypes confer different risk for celiac disease. The associated risk of celiac disease for DR3-DRB3*01:01:02-DQA1*05:01-DQB1*02:01 is predominant among patients of Scandinavian ethnicity. © 2017 John Wiley & Sons A/S.

Full Text Available Em 2009, o aparecimento de casos da gripe A(H1N1 - a chamada gripe suína - em 207 países indicou o registro da primeira pandemia do século XXI, como já previam os informes dos órgãos sanitários há alguns anos. No Brasil, foram confirmados 27.850 casos de suína, dos quais 1.632 evoluíram a óbito, representando 18,6% das mortes mundiais e 27,7% no continente americano, segundo dados do Ministério da Saúde (2009. Os meios de comunicação brasileiros bem como os de outros países vincularam o surgimento da gripe suína como uma "reedição" diferenciada da gripe espanhola, devido à identificação de um novo subtipo de vírus da gripe que podia ser tão letal quanto a antiga. Um temor semelhante havia sido vivenciado também com a gripe aviária, em 1997, que levou autoridades a permanecerem em estado de alerta. Este artigo tem por objetivo avaliar a produção das notícias sobre a gripe A(H1N1 nas três principais revistas de circulação nacional do Brasil. Para tanto, escolhemos as oito capas de Veja, IstoÉ e Época em que a doença foi destaque nos primeiros meses da pandemia, em 2009. Tomando como base noções ligadas à Análise do Discurso e às Teorias do Jornalismo, as análises indicam que o noticiário se divide em duas fases, enfatizando, inicialmente, o alarme provocado pelo medo diante do novo vírus e das mortes registradas e, em seguida, o controle pela constatação de que a moléstia representava menos risco do que se imaginava, além das ações para combatê-la.In 2009, the emergence of cases of influenza A(H1N1 - the popular flu - in 207 countries indicated the registration of the first pandemic of the XXI century, as predicted in reports from health authorities some years ago.

Full Text Available In commercial plantations of soybean in both the Southern and the Cerrado regions, contributions from biological nitrogen fixation (BNF are generally proportionately high. When using the 15N natural abundance technique to quantify BNF inputs, it is essential to determine, with accuracy, the 15N abundance of the N derived from BNF (the 'B' value. This study aimed to determine the effect of four recommended strains of Bradyrhizobium spp. (two B. japonicum and two B. elkanii on the 'B' value of soybean grown in pots in an open field using an equation based on the determination of δ15N natural abundance in a non-labelled soil, and estimate of the contribution of BNF derived from the use of 15N-isotope dilution in soils enriched with 15N. To evaluate N2 fixation by soybean, three non-N2-fixing reference crops were grown under the same conditions. Regardless of Bradyrhizobium strain, no differences were observed in dry matter, nodule weight and total N between labelled and non-labelled soil. The N2 fixation of the soybeans grown in the two soil conditions were similar. The mean 'B' values of the soybeans inoculated with the B. japonicum strains were -1.84 ‰ and -0.50 ‰, while those inoculated with B. elkanii were -3.67 ‰ and -1.0 ‰, for the shoot tissue and the whole plant, respectively. Finally, the 'B' value for the soybean crop varied considerably in function of the inoculated Bradyrhizobium strain, being most important when only the shoot tissue was utilised to estimate the proportion of N in the plant derived from N2 fixation.Em plantações comerciais de soja na região Sul e do Cerrado, as contribuições da fixação biológica de Nitrogênio (FBN são geralmente elevadas.

Full Text Available O objetivo deste experimento foi avaliar a influência da variação do nível de energia metabolizável na dieta de frangos de corte, associada a uma variação proporcional da densidade nutricional da ração, sobre o desempenho das aves e sobre a composição da fração lipídica da carne. Foram avaliados separadamente machos e fêmeas da linhagem Cobb 500. Para análise de desempenho, foi utilizado um delineamento inteiramente casualizado em esquema fatorial 6x3, sendo seis níveis de energia metabolizável na ração (2.800, 2.900, 3.000, 3.100, 3.200 e 3.300kcal kg-1 e três idades ao abate (42, 49 e 56 dias. Foi utilizada a metodologia de superfície de resposta para estabelecer um modelo matemático, explicando o comportamento do peso vivo, do consumo de ração e da conversão alimentar. Para a avaliação da composição da fração lipídica da carne, determinou-se o teor de lipídeos totais e de colesterol na carne do peito, na coxa com pele e na coxa sem pele, seguindo um delineamento inteiramente casualizado em esquema fatorial 3x3x2, sendo três níveis de energia metabolizável na ração (2.800, 3.000 e 3.300kcal kg-1 de ração, três idades ao abate (42, 49 e 56 dias e dois sexos. A redução da energia metabolizável da ração até valores próximos de 3.000kcal kg-1 não afetou o peso vivo, mas, reduzindo a energia da ração abaixo desse valor, o peso vivo diminui. O consumo de ração foi menor quando o nível energético da ração foi mais alto. A conversão alimentar melhorou de forma proporcional ao aumento do nível energético da ração. O desempenho de todas as aves ficou dentro da faixa considerada adequada para a linhagem. A carne de peito apresentou menos lipídeos totais e colesterol que a carne da coxa. O teor de lipídeos totais da coxa com pele foi mais que o dobro da coxa sem pele, mas o teor de colesterol não diferiu com a retirada da pele, demonstrando que o colesterol não está associado à gordura

Helichrysum plicatum (Turkish Helichrysum) has been used in folk medicine for the treatment of gastric and hepatic disorders. The aim of the present study was to examine the relaxant activity of an extract of H. plicatum flowers on isolated rat ileum. Segments of ileum of rats were suspended in an organ bath. Cumulative concentrations of H. plicatum ethanol extract induced a relaxant effect on spontaneous rat ileum contractions. H. plicatum extract caused a mean contractile response of 81.68 +/- 6.17% (at a dose of 0.01 mg/mL) and 30.08 +/- 9.07% (at a dose of 1 mg/mL). A similar effect was observed with papaverine (0.01-3 microg/mL). H. plicatum extract (0.01-1 mg/mL) relaxed high K+ (80 mM) precontractions, an effect similar to that caused by papaverine (0.01-3 microg/mL). The plant extract (0.03-0.3 mg/mL) also induced a significant depression of the cumulative concentration response curve for acetylcholine (5-1500 nM) (p Helichrysum plicatum flowers on the isolated rat intestine Extract of H. plicatum can inhibit the spontaneous ileum contractions and contractions induced by acetylcholine, histamine, barium and potassium ions.

Following a review of contract classification, they are differentiated according to the nature of the co-contracting parties, the purpose of the contract itself, the procedure for drawing up the contracts, and payment. The operations prior to the contract vary in that they may include a call for tenders, an option for delays or a letter of intent. (NEA) [fr

The Lasserre/Sum-of-Squares (SoS) hierarchy is a systematic procedure for constructing a sequence of increasingly tight semidefinite relaxations. It is known that the hierarchy converges to the 0/1 polytope in n levels and captures the convex relaxations used in the best available approximation algorithms for a wide variety of optimization problems.

Gravitational lens produces an odd number of images
International Nuclear Information System (INIS)
McKenzie, R.H.
1985-01-01
Rigorous results are given to the effect that a transparent gravitational lens produces an odd number of images. Suppose that p is an event and T the history of a light source in a globally hyperbolic space-time (M,g). Uhlenbeck's Morse theory of null geodesics is used to show under quite general conditions that if there are at most a finite number n of future-directed null geodesics from T to p, then M is contractible to a point. Moreover, n is odd and 1/2 (n-1) of the images of the source seen by an observer at p have the opposite orientation to the source. An analogous result is noted for Riemannian manifolds with positive definite metric

The use of radioactive indicators for the determination of the distribution coefficients of 46 elements on SnO 2 in 0.1N HNO 3 -acetone media is described. The determination has been carried out in static conditions: labelled element solution has been agitated with SnO 2 for two hours; the elements have been labelled with radioisotopes generally obtained by (n, γ) reaction, by irradiating a part of the used salt in EL 3 or OSIRIS reactor in the C.E.N. Saclay (France). Results show that the elements may be classified into several groups, according to their oxidation state. (T.I.)

Galilean contractions of W-algebras
Directory of Open Access Journals (Sweden)
Jørgen Rasmussen
2017-09-01
Full Text Available Infinite-dimensional Galilean conformal algebras can be constructed by contracting pairs of symmetry algebras in conformal field theory, such as W-algebras. Known examples include contractions of pairs of the Virasoro algebra, its N=1 superconformal extension, or the W3 algebra. Here, we introduce a contraction prescription of the corresponding operator-product algebras, or equivalently, a prescription for contracting tensor products of vertex algebras. With this, we work out the Galilean conformal algebras arising from contractions of N=2 and N=4 superconformal algebras as well as of the W-algebras W(2,4, W(2,6, W4, and W5. The latter results provide evidence for the existence of a whole new class of W-algebras which we call Galilean W-algebras. We also apply the contraction prescription to affine Lie algebras and find that the ensuing Galilean affine algebras admit a Sugawara construction. The corresponding central charge is level-independent and given by twice the dimension of the underlying finite-dimensional Lie algebra. Finally, applications of our results to the characterisation of structure constants in W-algebras are proposed.

The W(sl(N+3), sl(3)) algebra and their contractions to W3
International Nuclear Information System (INIS)
Bellucci, S.
1996-09-01
The authors construct the nonlinear W(sl(N+3), sl(3)) algebras and find the spectrum of values of the central charge that gives rise, by contracting the W(sl(N+3), sl(3)) algebras, to a W 3 algebra belonging to the coset W((sl(N+3), sl(3)/(u(1) x sl(N)). Using the tool of embedding the W(sl(N+3), sl(3)) algebras into linearizing algebras, the authors construct new realization of W 3 modulo null fields. The possibility to reproduce, within the conformal linearization framework, the central charge spectrum for minimal models of the nonlinear W(sl(N+3), sl(3)) algebras is discussed at the end

NMR investigations of larger macromolecules (>20 kDa) are severely hindered by rapid 1H and 13C transverse relaxation. Replacement of non-exchangeable protons with deuterium removes many efficient 1H-1H and 1H-13C relaxation pathways. The main disadvantage of deuteration is that many of the protons which would normally be the source of NOE-based distance restraints are removed. We report the development of a novel labeling strategy which is based on specific protonation and 14N-labeling of the residues phenylalanine, tyrosine, threonine, isoleucine and valine in a fully deuterated, 15N-labeled background. This allows the application of heteronuclear half-filters, 15N-editing and 1H-TOCSY experiments to select for particular magnetization transfer pathways. Results from investigations of a 47 kDa dimeric protein labeled in this way demonstrated that the method provides useful information for the structure determination of large proteins

TBC1D1 (tre-2/USP6, BUB2, cdc16 domain family member 1) is a Rab-GAP (GTPase-activating protein) that is highly expressed in skeletal muscle, but little is known about TBC1D1 regulation and function. We studied TBC1D1 phosphorylation on three predicted AMPK (AMP-activated protein kinase) phosphorylation sites (Ser231, Ser660 and Ser700) and one predicted Akt phosphorylation site (Thr590) in control mice, AMPKα2 inactive transgenic mice (AMPKα2i TG) and Akt2-knockout mice (Akt2 KO). Muscle contraction significantly increased TBC1D1 phosphorylation on Ser231 and Ser660, tended to increase Ser700 phosphorylation, but had no effect on Thr590. AICAR (5-aminoimidazole-4-carboxyamide ribonucleoside) also increased phosphorylation on Ser231, Ser660 and Ser700, but not Thr590, whereas insulin only increased Thr590 phosphorylation. Basal and contraction-stimulated TBC1D1 Ser231, Ser660 and Ser700 phosphorylation were greatly reduced in AMPKα2i TG mice, although contraction still elicited a small increase in phosphorylation. Akt2 KO mice had blunted insulin-stimulated TBC1D1 Thr590 phosphorylation. Contraction-stimulated TBC1D1 Ser231 and Ser660 phosphorylation were normal in high-fat-fed mice. Glucose uptake in vivo was significantly decreased in tibialis anterior muscles overexpressing TBC1D1 mutated on four predicted AMPK phosphorylation sites. In conclusion, contraction causes site-specific phosphorylation of TBC1D1 in skeletal muscle, and TBC1D1 phosphorylation on AMPK sites regulates contraction-stimulated glucose uptake. AMPK and Akt regulate TBC1D1 phosphorylation, but there must be additional upstream kinases that mediate TBC1D1 phosphorylation in skeletal muscle.

The DA transporter (DAT), a phosphoprotein, controls extracellular dopamine (DA) levels in the central nervous system through transport or reverse transport (efflux). Multiple lines of evidence support the claim that PKC significantly contributes to amphetamine-induced DA efflux. Other signaling pathways, involving CaMKII and ERK, have also been shown to regulate DAT mediated efflux. Here we assessed the contribution of putative PKC residues (S4, S7, S13) in the N-terminal of the DAT to amphetamine-induced DA efflux by transfecting DATs containing different serine to alanine (S-A) point mutations into DA pre-loaded HEK-293 cells and incubating these cells in amphetamine (2μM). The effects of a S-A mutation at the non-PKC residue S12 and a threonine to alanine (T-A) mutation at the ERK T53 residue were also assessed for comparison. WT-DATs were used as controls. In an initial experiment, we confirmed that inhibiting PKC with Go6976 (130nM) significantly reduced amphetamine-induced DA efflux. In subsequent experiments, cells transfected with the S4A, S12A, S13A, T53A and S4,7,13A mutants showed a reduction in amphetamine-induced DA efflux similar to that observed with Go6976. Interestingly, cells transfected with the S7A mutant, identified by some as a PKC-PKA residue, showed unperturbed WT-DAT levels of amphetamine-induced DA efflux. These results indicate that phosphorylation by PKC of select residues in the DAT N-terminal can regulate amphetamine-induced efflux. PKC can act either independently or in concert with other kinases such as ERK to produce this effect. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Os experimentos foram desenvolvidos em Adamantina, na Estação Experimental de Agronomia da Alta Paulista do Instituto Agronômico (IAC, nos anos agrícolas 1989/90, 1990/91 e 1991/92. O delineamento estatístico adotado foi o de blocos ao acaso com quatro repetições e oito tratamentos. Os tratamentos consistiram em faixas com 0,0; 0,5; 1,0; 1,5; 2,0; 2,5 e 3,0 m de largura capinadas ao longo da linha de plantio e mantidas sempre livres de plantas daninhas; além dessas, mateve-se uma faixa de 1,0 m de largura e mesmo procedimento, na qual a comunidade infestante das entrelinhas era roçada manual- mente sempre que a altura média de 0,3 m era atingida. Concluiu-se que faixas de capina menores do que 1,0 m aplicadas sobre a linha de plantio da cultura diminuíram a produção de grãos, o número de racemos e a altura da mamoneira.Three experiments were carried out in Adamantina at the Experimental Station of Agronomy of Alta Paulista, Instituto Agronômico (IAC, State of São Paulo, Brazil, on a Dark Red Latosol during 1989-1992, in order to study the effects of different row widths covered by weeds on the yield, height and number of racemes of IAC-80 castor bean cultivar.

Full Text Available Neste trabalho propusemo-nos a avaliar a fundibilidade de uma liga de cobalto-cromo (VERA-PDI em função da utilização de três revestimentos: Knebel (aglutinado por sílica, Termocast e Wirovest (aglutinados por fosfato e duas temperaturas de aquecimento para o molde (900°C e 950°C. Para a execução do teste foi utilizado o método descrito por HINMAN et al.9 (1985. O método de fundição foi o de cera perdida sob chama de gás-oxigênio. Os dados obtidos foram submetidos a análise estatística e demonstraram não haver diferença estatisticamente significante para os revestimentos Knebel e Wirovest, e diferença estatisticamente significante ao nível de 0,1% para o revestimento Termocast quando da variação da temperatura de aquecimento do molde. Quando analisamos os revestimentos sob temperatura do molde de 900°C verificamos diferença estatisticamente significante entre Knebel e Termocast e Knebel e Wirovest ao nível de 0,1%, e diferença entre Termocast e Wirovest ao nível de 5%. Para a temperatura de 950°C houve diferença estatisticamente significante ao nível de 0,1% entre todos os revestimentos. Dentro dos parâmetros utilizados neste estudo pudemos concluir que, para a liga VERA-PDI, a utilização do revestimento Knebel e temperatura de aquecimento do molde de 950°C proporcionaram melhores resultados quanto à fundibilidade.

The classical human leukocyte antigen (HLA)-DRB1*03:01 and HLA-DRB1*04:01 alleles are established autoimmune hepatitis (AIH) risk alleles. To study the immune-modifying effect of these alleles, we imputed the genotypes from genome-wide association data in 649 Dutch AIH type-1 patients. We therefore compared the international AIH group (IAIHG) diagnostic scores as well as the underlying clinical characteristics between patients positive and negative for these HLA alleles. Seventy-five percent of the AIH patients were HLA-DRB1*03:01/HLA-DRB1*04:01 positive. HLA-DRB1*03:01/HLA-DRB1*04:01-positive patients had a higher median IAIHG score than HLA-DRB1*03:01/HLA-DRB1*04:01-negative patients (P<0.001). We did not observe associations between HLA alleles and alanine transaminase levels (HLA-DRB1*03:01: P=0.2; HLA-DRB1*04:01; P=0.5); however, HLA-DRB1*03:01 was independently associated with higher immunoglobulin G levels (P=0.04). The HLA-DRB1*04:01 allele was independently associated with presentation at older age (P=0.03) and a female predominance (P=0.04). HLA-DRB1*03:01-positive patients received immunosuppressive medication and liver transplantation. In conclusion, the HLA-DRB1*03:01 and HLA-DRB1*04:01 alleles are both independently associated with the aggregate diagnostic IAIHG score in type-1 AIH patients, but are not essential for AIH development.

Acne vulgaris is a multifactorial disorder which is ideally treated with combination therapy with topical retinoids and antibiotics. The present study was conducted to compare the efficacy and safety of tazarotene plus clindamycin against adapalene plus clindamycin in facial acne vulgaris. This study is a randomized, open-label, parallel design clinical trial conducted on 60 patients with facial acne at the outpatient dermatology department in a tertiary healthcare center. The main outcome measures were change in the acne lesion count, Investigator's Static Global Assessment (ISGA) score, Global Acne Grading System (GAGS) score, and Acne-Specific Quality of Life Questionnaire (Acne-QoL) at the end of 4 weeks of therapy. After randomization one group (n = 30) received tazarotene 0.1% plus clindamycin 1% gel and another group (n = 30) received adapalene 0.1% plus clindamycin 1% gel for 1 month. At follow-up, all the parameter were reassessed. In both treatment regimens the total number of facial acne lesions decreased significantly. The difference in the change in the total count between the two combination regimens was also significant [6.51, 95% confidence interval (CI) 1.91-11.09, p = 0.007]. A ≥50% reduction in the total lesion count from the baseline levels was achieved by 71% of patients in the tazarotene plus clindamycin group and 22% of patients in the adapalene plus clindamycin group (p = 0.0012). The difference in the change of inflammatory (p = 0.017) and non-inflammatory (p = 0.039) lesion counts in the tazarotene plus clindamycin group were significantly higher than the adapalene plus clindamycin group. The difference in change of the GAGS score was also significantly higher in the tazarotene plus clindamycin group (p = 0.003). The ISGA score improved in 17 patients in the tazarotene plus clindamycin group versusnine patients in the adapalene plus clindamycin group (p = 0.04). The change of total quality-of-life score was found to be

The aim of this study was to analyze the neuromuscular mechanisms involved in the torque decrease induced by submaximal electromyostimulation (EMS) of the quadriceps muscle. It was hypothesized that torque decrease after EMS would reflect the fatigability of the activated motor units (MUs), but also a reduction in the number of MUs recruited as a result of changes in axonal excitability threshold. Two experiments were performed on 20 men to analyze 1) the supramaximal twitch superimposed and evoked at rest during EMS (Experiment 1, n = 9) and 2) the twitch response and torque-frequency relation of the MUs activated by EMS (Experiment 2, n = 11). Torque loss was assessed by 15 EMS-evoked contractions (50 Hz; 6 s on/6 s off), elicited at a constant intensity that evoked 20% of the maximal voluntary contraction (MVC) torque. The same stimulation intensity delivered over the muscles was used to induce the torque-frequency relation and the single electrical pulse evoked after each EMS contraction (Experiment 2). In Experiment 1, supramaximal twitch was induced by femoral nerve stimulation. Torque decreased by ~60% during EMS-evoked contractions and by only ~18% during MVCs. This was accompanied by a rightward shift of the torque-frequency relation of MUs activated and an increase of the ratio between the superimposed and posttetanic maximal twitch evoked during EMS contraction. These findings suggest that the torque decrease observed during submaximal EMS-evoked contractions involved muscular mechanisms but also a reduction in the number of MUs recruited due to changes in axonal excitability.

Our recent studies have shown that the difference in basal pain sensitivity to mechanical and thermal stimulation between Dark-Agouti (DA) rats and a novel congenic DA.1U rats is major histocompatibility complex (MHC) genes dependent. In the present study, we further used DA and DA.1U rats to investigate the role of MHC genes in formalin-induced pain model by behavioral, electrophysiological and immunohistochemical methods. Behavioral results showed biphasic nociceptive behaviors increased significantly following the intraplantar injection of formalin in the hindpaw of DA and DA.1U rats. The main nociceptive behaviors were lifting and licking, especially in DA rats (PDA rats were significantly higher than those in DA.1U rats in both phases of the formalin test (PDA rats was significantly higher than that of DA.1U rats (PDA was greater than that in DA.1U rats (PDA rats was significantly higher than that in DA.1U rats in the respective experimental group (PDA and DA.1U rats exhibited nociceptive responses in formalin-induced pain model and DA rats were more sensitive to noxious chemical stimulus than DA.1U rats, indicating that MHC genes might contribute to the difference in pain sensitivity.

There exist families of field theories with symmetry group SO(N) (or SU(N)) that become simpler as N becomes larger. More precisely, the solutions to these theories possess an expansion in powers of 1/N. This expansion is the subject of these lectures. The 1/N expansion can be used to analyze model field theories. The 1/N expansion is developed for phi 4 theory and applied to two two-dimensional models with similar combinatoric structures, the Gross-Neveu model and the CP/sup N-1/ model. These models display (in the leading 1/N approximation) such interesting phenomena as asymptotic freedom, dynamical symmetry breaking, dimensional transmutation, and non-perturbative confinement. It is possible that the 1/N expansion, with N the number of colors, might fruitfully be applied to quantum chromodynamics. Unfortunately, it is not possible to make a decisive test of the approximation, because no one knows how to compute even the first term in the expansion in closed form. However, it is possible to argue that this first term, whatever its detailed form, has many properties that are also shared by the real world, and which are otherwise underived from field theory. These include the saturation of scattering amplitudes by an infinite number of narrow resonances, the essential feature of dual-resonance models

Full Text Available Este trabalho avalia os retornos e os riscos de estratégias de hedge para as dez principais regiões produtoras de soja do Brasil em relação aos contratos futuros de soja da Chicago Board of Trade (CBOT. Verificou-se que as bases apresentaram padrão bem definido: fortalecimento entre maio e novembro, seguido por enfraquecimento nos seis meses subsequentes. Os hedgers de compra possuem oportunidades de obter retornos brutos maiores, mas os riscos envolvidos nas estratégias de hedge de compra também são maiores. Conclui-se que os contratos de soja em grão da CBOT apresentam diferentes possibilidades de retornos brutos em função do tipo de hedge, do período hedgeado e do contrato utilizado. Logo, as informações disponibilizadas neste trabalho se apresentam como importante subsídio ao processo de tomada de decisão por parte dos agentes da cadeia agroindustrial da soja.This paper analyzes the return and risks of hedging strategies of the major ten soybean producing regions in Brazil concerning Chicago Board of Trade (CBOT future contracts. It was verified that the bases presented a well defined pattern characterized by strengthening from May to November and weakening in the remaining months. Long hedging had larger returns and larger risks comparing with short hedging. The conclusion of this study is that the CBOT soybean contracts present different returns depending on the type of hedging, on the period of hedging, and on the contract used. Therefore, the information presented in this paper is very important to support the decision making process in the Brazilian soybean agricultural system.

To quantify plasma concentrations and determine adverse ocular, renal, or hepatic effects associated with repeated topical ophthalmic application of 0.1% diclofenac to healthy cats. 8 healthy sexually intact male cats. A randomized, placebo-controlled crossover study was conducted. A topical formulation of 0.1% diclofenac was administered 4 times/d for 7 days to 4 cats, and artificial tear (control) solution was administered to the other 4 cats. After a 12-day washout period, cats received the other treatment. Ophthalmic examinations were performed daily. Plasma samples were obtained on days 1 and 7 for pharmacokinetic analysis. A CBC, serum biochemical analysis, urinalysis, determination of urine protein-to-creatinine ratio, and determination of glomerular filtration rate were performed before the start of the study and after each 7-day treatment period. Mild conjunctival hyperemia was the only adverse ocular effect detected. Maximal drug concentration and area under the curve were significantly higher on day 7 than on day 1. Diclofenac-treated cats had a significantly lower glomerular filtration rate than did control-treated cats after the second but not after the first treatment period, presumably associated with iatrogenic hypovolemia. Topical ophthalmic administration of 0.1% diclofenac was well tolerated in healthy cats, with only mild signs of ocular irritation. Detectable systemic concentrations of diclofenac were achieved with accumulation over 7 days. Systemic absorption of diclofenac may be associated with reduced glomerular filtration rate, particularly in volume-contracted animals. Topical ophthalmic 0.1% diclofenac should be used with caution in volume-contracted or systemically ill cats.

Insulin-like growth factor I (IGF-I) has been positively correlated with cognitive ability. Cognitive decline in minimal hepatic encephalopathy (MHE) was shown to be induced by elevated intracranial dopamine (DA). The beneficial effect of IGF-I signaling in MHE remains unknown. In this study, we found that IGF-I content was reduced in MHE rats and that IGF-I administration mitigated cognitive decline of MHE rats. A protective effect of IGF-I on the DA-induced interaction between postsynaptic density protein 95 (PSD95) and neuronal nitric oxide synthase (nNOS) was found in neurons. Ribosomal S6 protein kinase (RSK) phosphorylated nNOS in response to IGF-I by recruiting extracellular signal-regulated kinase (ERK1/2). In turn, DA inactivated the ERK1/2/RSK pathway and stimulated the PSD95-nNOS interaction by downregulating IGF-I. Inhibition of the interaction between PSD95 and nNOS ameliorated DA-induced memory impairment. As DA induced deficits in the ERK1/2/RSK pathway and the interaction between PSD95 and nNOS in MHE brains, IGF-I administration exerted a protective effect via interruption of the interaction between PSD95 and nNOS. These results suggest that IGF-I antagonizes DA-induced cognitive loss by disrupting PSD95-nNOS interactions in MHE.

Torsional oscillations of increasing frequencies with constant torsional strain amplitude, {theta}, of 3.1 x 10{sup -4} were superimposed on wires of Al-1 wt% Si and Al-1 wt% Si-0.1 wt% Zr-0.1 wt% Ti alloys, while being crept under constant stress (52.3 MPa) and different testing temperatures. It was found that increasing the frequency of oscillations resulted in an increase of both transient and steady state creep. In the transient stage, while the exponent n is increasing with frequency v, the parameter {beta} decreases. Zirconium and titanium addition generally reduced the rate of creep. A value of 20 kJ/mol was found for the activation energy of the mechanism operating in the transient and steady state stages which was ascribed as being due to dislocation intersection. (orig.)

Following discussion at TREF and on the recommendation of the Finance Committee, Council approved a new staff contract policy, which became effective on 1 January 2006. Its application is covered by a new Administrative Circular No. 2 (Rev. 3) 'Recruitment, appointment and possible developments regarding the contractual position of staff members'. The revised circular replaces the previous Circulars No. 9 (Rev. 3) 'Staff contracts' and No. 2 (Rev. 2) 'Guidelines and procedures concerning recruitment and probation period for staff members'. The main features of the new contract policy are as follows: The new policy provides chances for long-term employment for all staff recruits staying for four years without distinguishing between those assigned to long-term or short-term activities when joining CERN. In addition, it presents a number of simplifications for the award of ICs. There are henceforth only 2 types of contract: Limited Duration (LD) contracts for all recruitment and Indefinite Contracts (IC) for...

Full Text Available Several models have been developed to evaluate reproductive status of cows through concentration of progesterone in milk, the effect of sex selection in the commercial production of herds and bioeconomic performance of the multiple ovulation and embryo transfer system in select herds. However, models describing the production of embryos in superovulated females have yet to be developed. A probability density function of the number of embryos collected by donors of the Nelore breed was determined. Records of 61,928 embryo collections from 26,767 donors from 1991 to 2005 were analyzed. Data were provided by the Brazilian Association of Creators of Zebu and Controlmax Consultoria e Sistemas Ltda. The probability density function of the number of viable embryos was modeled using exponential and gamma distributions. Parameter fitting was carried out for maximum likelihood using a non-linear gradient method. Both distributions presented similar level of precision: root mean square error (RMSE = 0.0072 and 0.0071 for the exponential and gamma distributions, respectively; both distributions are thus deemed suitable for representing the probability density function of embryo production by Nelore females.Diversos modelos têm sido desenvolvidos para avaliar o estado reprodutivo de vacas por meio da concentração de progesterona no leite, o efeito da seleção do sexo na produção comercial de rebanhos e o desempenho bioeconômico da ovulação múltipla e transferência de embriões em rebanhos selecionados.

Full Text Available Infection with Helicobacter pylori is a major risk factor for development of gastric disease, including gastric cancer. Patients infected with H. pylori strains that express CagA are at even greater risk of gastric carcinoma. Given the importance of CagA, this report describes a new molecular mechanism by which the cagA copy number dynamically expands and contracts in H. pylori. Analysis of strain PMSS1 revealed a heterogeneous population in terms of numbers of cagA copies; strains carried from zero to four copies of cagA that were arranged as direct repeats within the chromosome. Each of the multiple copies of cagA was expressed and encoded functional CagA; strains with more cagA repeats exhibited higher levels of CagA expression and increased levels of delivery and phosphorylation of CagA within host cells. This concomitantly resulted in more virulent phenotypes as measured by cell elongation and interleukin-8 (IL-8 induction. Sequence analysis of the repeat region revealed three cagA homologous areas (CHAs within the cagA repeats. Of these, CHA-ud flanked each of the cagA copies and is likely important for the dynamic variation of cagA copy numbers. Analysis of a large panel of clinical isolates showed that 7.5% of H. pylori strains isolated in the United States harbored multiple cagA repeats, while none of the tested Korean isolates carried more than one copy of cagA. Finally, H. pylori strains carrying multiple cagA copies were differentially associated with gastric disease. Thus, the dynamic expansion and contraction of cagA copy numbers may serve as a novel mechanism by which H. pylori modulates gastric disease development.

Highlights: • Patients with H1N1 pneumonia demonstrated more opacified zones on chest x-ray than patients with non-H1N1 pneumonias. • A particular ‘phenotype’ of chest x-ray changes was identified in H1N1 patients. • This H1N1 ‘phenotype’ was the same for the two evaluated ‘flu seasons, during both pandemic and post pandemic stages. - Abstract: Aims: To review, phenotype and assess potential prognostic value of initial chest X-ray findings in patients with H1N1 influenza during seasonal outbreaks of 2009 and 2010, in comparison with non-H1N1, community acquired pneumonia (CAP). Methods: We retrospectively identified 72 patients admitted to hospital with pneumonia during the seasons of 2009 and 2010. H1N1 cases were confirmed by virology PCR. Presenting chest X-rays were jointly read by 2 radiologists, who were ‘blinded’ to further patient details and divided into 6 zones. Total number of opacified zones, the pattern and distribution of changes and length of hospital stay were recorded. Results: Patients with H1N1 demonstrated more opacified zones (mean of 2.9 compared with 2.0; p = 0.006), which were bilateral in two-thirds compared with a quarter of those with non-H1N1 CAP (p = 0.001). H1N1 radiographs were more likely to be ‘patchy’ versus ‘confluent’ changes of non-H1N1 CAP (p = 0.03) and more often demonstrated peripheral distribution (p = 0.01). H1N1 patients tended to stay in hospital longer (not significant; p = 0.08). A positive correlation existed between number of affected zones and length of inpatient stay, which was statistically significant for the cohorts combined (p = 0.02). The findings were the same for the two evaluated seasons. Conclusion: H1N1 patients demonstrated more extensive disease, which was more likely bilateral, ‘patchy’, and peripheral in distribution. With increasing global cases of H1N1, knowledge of the typical findings of the H1N1 presenting chest X-ray may assist with early triage of patients

Results: A total of 55.7% of hospitals contracted-out at least one of the generic services. The services most frequently contracted-out were housekeeping and maintenance and security(45.1 and 32.5%, respectively. In contrast, the services (94.3% and 80.1%, respectively. Hospital size (economies of scale, measured by the number of beds, was one of the most important factors influencing make or buy decisions. Conclusions: We find evidence that economies of scale are related to a higher level of vertical integration, while specialization and for-profit objectives favor the decision to contract-out. The choice of organizational model for laundry services presents a different pattern from that of the other three services. Empirical results show that some asset specificity could be present in laundry services.

We study molecular conductivity for a one-electron, bath-molecule-bath model Hamiltonian. The primary quantum-mechanical variable is the one-electron reduced density matrix (1-RDM). By identifying similarities between the steady-state Liouville equation and the anti-Hermitian contracted Schrödinger equation (ACSE) [D. A. Mazziotti, Phys. Rev. A 75, 022505 (2007)], we develop a way of enforcing nonequilibrium, steady-state behavior in a time-independent theory. Our results illustrate the relationship between current and voltage in molecular junctions assuming that the total number of electrons under consideration can be fixed across all driving potentials. The impetus for this work is a recent study by Subotnik et al. that also uses the 1-RDM to study molecular conductivity under different assumptions regarding the total number of electrons [J. E. Subotnik et al., J. Chem. Phys. 130, 144105 (2009)]. Unlike calculations in the previous study, our calculations result in 1-RDMs that are fully N-representable. The present work maintains N-representability through a bath-bath mixing that is related to a time-independent relaxation of the baths in the absence of the molecule, as governed by the ACSE. A lack of N-representability can be important since it corresponds to occupying energy states in the molecule or baths with more than one electron or hole (the absence of an electron) in violation of the Pauli principle. For this reason the present work may serve as an important, albeit preliminary, step in designing a 2-RDM/ACSE method for studying steady-state molecular conductivity with an explicit treatment of electron correlation.
Rac1 modulates G-protein-coupled receptor-induced bronchial smooth muscle contraction.

Increasing evidence suggests a functional role of RhoA/Rho-kinase signalling as a mechanism for smooth muscle contraction; however, little is known regarding the roles of Rac1 and other members of the Rho protein family. This study aimed to examine whether Rac1 modulates bronchial smooth muscle contraction. Ring preparations of bronchi isolated from rats were suspended in an organ bath, and isometric contraction of circular smooth muscle was measured. Immunoblotting was used to examine myosin light chain phosphorylation in bronchial smooth muscle. Our results demonstrated that muscle contractions induced by carbachol (CCh) and endothelin-1 (ET-1) were inhibited by EHT1864, a selective Rac1 inhibitor, and NSC23766, a selective inhibitor of Rac1-specific guanine nucleotide exchange factors. Similarly, myosin light chain and myosin phosphatase target subunit 1 (MYPT1) at Thr853 phosphorylation induced by contractile agonist were inhibited with Rac1 inhibition. However, contractions induced by high K + , calyculin A (a potent protein phosphatase inhibitor) and K + /PDBu were not inhibited by these Rac1 inhibitors. Interestingly, NaF (a G-protein activator)-induced contractions were inhibited by EHT1864 but not by NSC23766. We next examined the effects of a trans-acting activator of transcription protein transduction domain (PTD) fusion protein with Rac1 (PTD-Rac1) on muscle contraction. The constitutively active form of PTD-Rac1 directly induced force development and contractions were abolished by EHT1864. These results suggest that Rac1, activated by G protein-coupled receptor agonists, such as CCh and ET-1, may induce myosin light chain and MYPT phosphorylation and modulate the contraction of bronchial smooth muscle.

Upon titration of n-hexanol/cyclohexane mixtures of different molar compositions with water, water/n-hexanol clusters are formed in cyclohexane. Here, we develop a new method to estimate the water and n-hexanol aggregation numbers in the clusters that combines integration analysis in one-dimensional 1 H NMR spectra, diffusion coefficients calculated by diffusion-ordered NMR spectroscopy, and further application of the Stokes-Einstein equation to calculate the hydrodynamic volume of the clusters. Aggregation numbers of 5-15 molecules of n-hexanol per cluster in the absence of water were observed in the whole range of n-hexanol/cyclohexane molar fractions studied. After saturation with water, aggregation numbers of 6-13 n-hexanol and 0.5-5 water molecules per cluster were found. O-H and O-O atom distances related to hydrogen bonds between donor/acceptor molecules were theoretically calculated using density functional theory. The results show that at low n-hexanol molar fractions, where a robust hydrogen-bond network is held between n-hexanol molecules, addition of water makes the intermolecular O-O atom distance shorter, reinforcing molecular association in the clusters, whereas at high n-hexanol molar fractions, where dipole-dipole interactions dominate, addition of water makes the intermolecular O-O atom distance longer, weakening the cluster structure. This correlates with experimental NMR results, which show an increase in the size and aggregation number in the clusters upon addition of water at low n-hexanol molar fractions, and a decrease of these magnitudes at high n-hexanol molar fractions. In addition, water produces an increase in the proton exchange rate between donor/acceptor molecules at all n-hexanol molar fractions.
The effects of hospitals' governance on optimal contracts: bargaining vs. contracting.
Galizzi, Matteo M; Miraldo, Marisa
2011-03-01
We propose a two-stage model to study the impact of different hospitals' governance frameworks on the optimal contracts designed by third-party payers when patients' disease severity is the private information of the hospital. In the second stage, doctors and managers interact within either a bargaining or a contracting scenario. In the contracting scenario, managers offer a contract that determines the payment to doctors, and doctors decide how many patients to treat. In the bargaining scenario, doctors and managers strategically negotiate on both the payment to doctors and the number of patients to treat. We derive the equilibrium doctors' payments and number of treated patients under both scenarios. We then derive the optimal contract offered by the government to the hospital in the first stage. Results show that when the cost of capital is sufficiently low, the informational rent is lower, and the social welfare is higher, in the contracting scenario. Copyright © 2010 Elsevier B.V.

To investigate the pathophysiology of human spleen, splenic contraction following subcutaneous injection of epinephrine was measured in 45 patients with various disorders using single photon emission computed tomography (SPECT). The splenic contraction rates and percent decreases in splenic counts (ejection rates) in 5 controls were 34.5 +- 10.0 percent (mean +- SD) and 16.4 +- 6.9 percent respectively. With regard to non-Hodgkin lymphoma, the splenic contraction and ejection rates in 8 patients with no splenic involvement diagnosed by CT and/or /sup 67/Ga scintigraphy were 27.3 +- 7.0 percent and 9.4 +- 7.0 percent respectively, while these values in 6 patients with splenic involvement diagnosed by presence of splenomegaly, CT and/or /sup 67/Ga scintigraphy were 12.8 +- 5.8 percent and 2.5 +- 1.6 percent respectively. Both the values in the patients with splenic involvement were low (p < 0.01, p < 0.1) compared with those in the patients without splenic involvement. The splenic contraction and ejection rates in 7 patients with splenomegaly due to portal hypertension were averaged 33.5 +- 6.7 percent and 13.8 +- 4.5 percent respectively. These values were comparable to those in controls. All 3 patients with leukemia and splenomegaly showed exceedingly low values of the splenic contraction and ejection rates. The values were also remarkably low in a patient with splenic metastasis of unknown origin.

Purpose: The objective of our study was to demonstrate differences in relapse rates, total survival times, and complication rates between inguinofemoral radiation and its absence in cases of invasive vulvar carcinoma without lymph node involvement (FIGO Stages T1, N0-1). Methods and Materials: From 1974 to 1990, 135 patients with invasive vulvar carcinoma in Stage T1 without clinical evidence of inguinal lymph node involvement underwent simple vulvectomy performed by hot-knife resection without lymphadenectomy. Although 65 patients (Group 1) received postoperative inguinofemoral radiation therapy, 70 patients (Group 2) did not, and none received local vulva irradiation. Results: The 5-year survival rates were 93.7% in Group 1 and 91.4% in Group 2 (p = NS). Although clitoris involvement was significantly more prevalent in the irradiation group (p = 0.04), inguinal relapse was found less frequently in Group 1 (4.6% or 3 out of 65 patients) than in group 2 (10% or 7 out of 70 patients) (p = 0.32). The complication rates were, 7.7% in Group 1 and 2.9% in Group 2, 2.7% for vaginal stenosis (two patients in each group), 1.5% for inguinal pain (one patient in Group 1), 1.5% for recto vaginal fistula (one patient in Group 1), 1.5% for vulvar infection (one patient in Group 1). Conclusion: No statistically significant differences in the relapse rates and survival times were found. Risk factors were equally distributed in both study groups except for clitoris involvement. The 5-year survival rates in both groups were similar to those reported in the literature for radical vulvectomy and inguinal lymph-node dissection (83-96%). Morbidity in our study was low. Although our data showed similar results in both groups, we are not recommending at this time to omit groin radiation in general, but it may be justified in low-risk cases

2012-12-01
Full Text Available La tipología de los perjuicios a lo largo de la historia ha oscilado entre el reconocimiento y la negación de determinadas categorías; en este desarrollo, las categorías que conforman el daño material –lucro cesante y daño emergente– parecen haberse asentado; otra es la suerte de los perjuicios inmateriales, pues es cierto que el daño moral en alguna medida tiene una estabilidad similar a la que ostentan los daños materiales, pero del segundo rubro no puede afirmarse lo mismo, en particular cuando se trata de lesiones sobre la integridad personal. La jurisprudencia nacional fue, en principio, reticente a reconocer una categoría distinta a la del daño moral, al punto de que la Corte Suprema solo reconoció otro perjuicio en 2008, pero una vez aceptado el reconocimiento de otro rubro, el cambio ha sido constante: ha cambiado de nombre y contenido, de perjuicio fisiológico a daño a la vida de relación, luego a alteración grave de las condiciones de existencia y, por último, al daño a la salud. Daño este último que se aborda con las vicisitudes históricas que rodearon a sus antecesores y con la necesaria referencia del principio de reparación integral, arbitrio del juez e igualdad para los administrados, al tiempo que se le enmarca en la constitucionalización del derecho de daños. El análisis que del mismo se hace no se reduce a su conceptualización o a un análisis teórico, sino que el texto arroja las herramientas para la aplicación, tasación y reconocimiento de este perjuicio, con lo cual facilita la labor de los operadores jurídicos al momento de identificar la tipología de los perjuicios, de solicitar o reconocer los mismos de manera adecuada.
Vagally mediated effects of brain stem dopamine on gastric tone and phasic contractions of the rat.
Anselmi, L; Toti, L; Bove, C; Travagli, R A
2017-11-01
Dopamine (DA)-containing fibers and neurons are embedded within the brain stem dorsal vagal complex (DVC); we have shown previously that DA modulates the membrane properties of neurons of the dorsal motor nucleus of the vagus (DMV) via DA1 and DA2 receptors. The vagally dependent modulation of gastric tone and phasic contractions, i.e., motility, by DA, however, has not been characterized. With the use of microinjections of DA in the DVC while recording gastric tone and motility, the aims of the present study were 1 ) assess the gastric effects of brain stem DA application, 2 ) identify the DA receptor subtype, and, 3 ) identify the postganglionic pathway(s) activated. Dopamine microinjection in the DVC decreased gastric tone and motility in both corpus and antrum in 29 of 34 rats, and the effects were abolished by ipsilateral vagotomy and fourth ventricular treatment with the selective DA2 receptor antagonist L741,626 but not by application of the selective DA1 receptor antagonist SCH 23390. Systemic administration of the cholinergic antagonist atropine attenuated the inhibition of corpus and antrum tone in response to DA microinjection in the DVC. Conversely, systemic administration of the nitric oxide synthase inhibitor nitro-l-arginine methyl ester did not alter the DA-induced decrease in gastric tone and motility. Our data provide evidence of a dopaminergic modulation of a brain stem vagal neurocircuit that controls gastric tone and motility. NEW & NOTEWORTHY Dopamine administration in the brain stem decreases gastric tone and phasic contractions. The gastric effects of dopamine are mediated via dopamine 2 receptors on neurons of the dorsal motor nucleus of the vagus. The inhibitory effects of dopamine are mediated via inhibition of the postganglionic cholinergic pathway. Copyright © 2017 the American Physiological Society.

2005-01-01
We present experimentally obtained results of the piezoresistive effect in p-type silicon and strained Si0.9Ge0.1. Today, strained Si1-xGex is used for high speed electronic devices. This paper investigates if this area of use can be expanded to also cover piezoresistive micro electro mechanical...... systems (MEMS) devices. The measurements are performed on microfabricated test chips where resistors are defined in layers grown by molecular beam epitaxy on (0 0 1) silicon substrates. A uniaxial stress along the [1 1 0] direction is applied to the chip, with the use of a four point bending fixture....... The investigation covers materials with doping levels of N-A = 10(18) cm(-3) and NA = 1019 cm(-3), respectively. The results show that the pi(66) piezoresistive coefficient in strained Si0.9Ge0.1 is approximately 30% larger than the comparable pi(44) piezoresistive coefficient in silicon at a doping level of N...

An agent-based model is constructed in which a demand aggregator sells both uniform-price and real-time price (RTP) contracts to households as means for adding price elasticity in residential power use sectors, particularly during peak-price hours of the day. Simulations suggest that RTP contracts help a demand aggregator (1) shift its long-term contracts toward off-peak hours, thereby reducing its cost of power and (2) increase its short-run profits if it is one of the first aggregators to have large numbers of RTP contracts; but (3) create susceptibilities to short-term market demand and price volatilities.

The mechanism of action of endothelin-1 as compared with other agonists in vascular smooth muscle

1989-01-01
The effects of endothelin-1 (ET-1) on tension and membrane potential in rat isolated mesenteric resistance vessels (MRVs) and on 45Ca influx, 45Ca efflux, inositol-1,4,5-triphosphate (IP3) production, and cytoplasmic Ca2+ concentration ([Ca2+]1) in cultured aortic smooth muscle cells were compared with those of other agonists. ET-1 induced contractions of the MRVs, which were slow in onset, but reached a similar maximum amplitude (at 10 nM ET-1) as that seen with norepinephrine (NE, 10 microM) or [arg8]vasopressin (AVP, 0.1 microM). The EC50 for ET-1 was 1.3 +/- 0.1 nM. Removal of extracellular Ca2+ reduced ET-1-induced contractions to 11 +/- 3% of those in Ca2+-containing medium. With NE, the same procedure reduced contractions to 47 +/- 7% of those in Ca2+-containing medium, while with AVP, the reduction was similar in magnitude to that induced by ET-1 (11 +/- 5% of those in Ca2+-containing medium). Relaxation of ET-1-induced and NE-induced contractions by diltiazem was not complete (maximal at 58 +/- 6% with 10 microM diltiazem after 6 nM ET-1, and at 70 +/- 3% after 0.1 microM NE), in contrast to that of 80 mM K+-induced contractions, which were potently (IC50 = 0.2 microM) and completely reversed (100% relaxation at 10 microM diltiazem). ET-1 (6 nM) caused a small but significant depolarization of the MRVs (approximately 7 mV), the magnitude of which was only about one-third of that induced by equieffective contractile concentrations of NE and AVP. The voltage-sensitive Ca2+ channel agonist Bay K 8644 (1 microM), in contrast to ET-1, NE, and AVP, produced a small contraction (30 +/- 2% of the maximum response to NE), but no further depolarization when added in the presence of 15 mM K+ (which elicited approximately 12 mV depolarization but no contraction)

Full Text Available A hanseníase é uma doença infecciosa de evolução crônica causada pelo Mycobacterium leprae que acomete com maior frequência a mucosa nasal. Esse acometimento independe da forma clínica da doença e pode ocorrer mesmo antes do aparecimento de lesões na pele ou em outras partes do corpo. Faz-se necessário a vigilância epidemiológica dos contatos de casos novos de hanseníase para o diagnóstico precoce da doença. OBJETIVOS: Identificar lesões específicas e precoces de hanseníase por meio de exame endoscópico, baciloscópico, histopatológico e da reação em cadeia da polimerase em Tempo Real da mucosa das cavidades nasais dos contatos domiciliares e peridomiciliares com sorologia positiva para o antígeno glicolipídio fenólico. MATERIAL E MÉTODOS: Estudo prospectivo transversal em 31 contatos de pacientes de hanseníase com sorologia positiva (PGL-1, 05 controles negativos e 01 positivo no período de 2003 a 2006. RESULTADOS: Entre os contatos soropositivos a PCR-RT foi positiva para a presença de DNA de M. leprae em 06 (19,35% destes e o maior número de cópias do genoma do bacilo foi encontrado no contato que adoeceu. CONCLUSÃO: Isoladamente os exames da mucosa nasal não permitiram o diagnóstico precoce da hanseníase, mas com a combinação de vários métodos, o exame dos contatos pôde ajudar na identificação da infecção subclínica e monitoramento daqueles que poderiam ter papel importante na transmissão da doença.Leprosy is a chronic infectious disease caused by Mycobacterium leprae.

Exploratory hole UE20n number-sign 1 was drilled 305 m down hydraulic gradient of the Cheshire event (U20n) as part of the Radionuclide Migration Program at the Nevada Test Site. The hole was designed to investigate the possibility of groundwater transport of radionuclides from the U20n cavity region. Drilling reached a total depth of 1005.8 m. Composite static water levels in the borehole were measured at approximately 620 m below ground surface. The borehole penetrated about 386 m of saturated zone, which was comprised primarily of rhyolite lava flows of the Upper Rhyolite Lavas, Tuffs, and Rhyolites of Area 20. Evidence from UE20n number-sign 1 suggests the presence of a relatively more permeable zone in the 730 to 750-m depth interval. The neutron log suggests that greater quantities of water were present at depths between 729 and 747 m. Core collected over three depth intervals showed the highest fracture density in a reddish-grey rhyolite lava flow in the 733.8 to 738.1-m core interval. Groundwater flow away from U20n through this permeable zone is suggested by the UE20n number-sign 1 borehole temperature logs. Elevated 3 H activities were observed with the highest activities found near 732 m. The 3 H activities observed in the 732 to 802-m interval in UE20n number-sign 1 were of similar magnitude to those found in the cavity region in the U20n post-shot hole. The activities of 125 Sb and 85 Kr, which are known to be mobile in groundwater, were of similar magnitude to those found near the cavity region, while 137 Cs, which is thought to be adsorbed during transport, was found in activities two to three orders of magnitude lower than near the cavity. These temperature and radioisotope data suggest that radionuclide migration via groundwater flow may be occurring laterally from the U20n rubble chimney through the permeable zone located at the 730 to 750-m depth. 25 refs., 18 figs., 15 tabs
Why radiologists lose their hospital contracts: is your contract secure?
Muroff, Lawrence R
2010-03-01
Previously, a hospital contract meant tenure for the incumbent group of radiologists; however, those days are long gone. Exclusive contracts have morphed into exclusive contracts with carve-outs. Turf erosion has become a fact of life for radiology practices. Now radiologists are losing their hospital contracts in record numbers. Group size, though helpful for a variety of reasons, does not ensure that a practice will be secure in its hospital setting. The reasons that groups lose their hospital contracts are varied, and in this paper, the author discusses the most common ones. Suggestions to help practices avoid this unfortunate fate are presented.

Volume transmission results in phasic and tonic modulatory signals. The actions of tonic dopamine (DA) at type 1 DA receptors (D1Rs) are largely undefined. Here we show that tonic 5nM DA acts at D1Rs to stabilize neuronal output over minutes by enabling activity-dependent regulation of the hyperpolarization activated current (I h). In the presence but not absence of 5nM DA, I h maximal conductance (G max) was adjusted according to changes in slow wave activity in order to maintain spike timing. Our study on the lateral pyloric neuron (LP), which undergoes rhythmic oscillations in membrane potential with depolarized plateaus, demonstrated that incremental, bi-directional changes in plateau duration produced corresponding alterations in LP I hG max when preparations were superfused with saline containing 5nM DA. However, when preparations were superfused with saline alone there was no linear correlation between LP I hGmax and duty cycle. Thus, tonic nM DA modulated the capacity for activity to modulate LP I h G max; this exemplifies metamodulation (modulation of modulation). Pretreatment with the Ca2+-chelator, BAPTA, or the specific PKA inhibitor, PKI, prevented all changes in LP I h in 5nM DA. Calcineurin inhibitors blocked activity-dependent changes enabled by DA and revealed a PKA-mediated, activity-independent enhancement of LP I hG max. These data suggested that tonic 5nM DA produced two simultaneous, PKA-dependent effects: a direct increase in LP I h G max and a priming event that permitted calcineurin regulation of LP I h. The latter produced graded reductions in LP I hG max with increasing duty cycles. We also demonstrated that this metamodulation preserved the timing of LP's first spike when network output was perturbed with bath-applied 4AP. In sum, 5nM DA permits slow wave activity to provide feedback that maintains spike timing, suggesting that one function of low-level, tonic modulation is to stabilize specific features of a dynamic output.

Full Text Available Volume transmission results in phasic and tonic modulatory signals. The actions of tonic dopamine (DA at type 1 DA receptors (D1Rs are largely undefined. Here we show that tonic 5nM DA acts at D1Rs to stabilize neuronal output over minutes by enabling activity-dependent regulation of the hyperpolarization activated current (I h. In the presence but not absence of 5nM DA, I h maximal conductance (G max was adjusted according to changes in slow wave activity in order to maintain spike timing. Our study on the lateral pyloric neuron (LP, which undergoes rhythmic oscillations in membrane potential with depolarized plateaus, demonstrated that incremental, bi-directional changes in plateau duration produced corresponding alterations in LP I hG max when preparations were superfused with saline containing 5nM DA. However, when preparations were superfused with saline alone there was no linear correlation between LP I hGmax and duty cycle. Thus, tonic nM DA modulated the capacity for activity to modulate LP I h G max; this exemplifies metamodulation (modulation of modulation. Pretreatment with the Ca2+-chelator, BAPTA, or the specific PKA inhibitor, PKI, prevented all changes in LP I h in 5nM DA. Calcineurin inhibitors blocked activity-dependent changes enabled by DA and revealed a PKA-mediated, activity-independent enhancement of LP I hG max. These data suggested that tonic 5nM DA produced two simultaneous, PKA-dependent effects: a direct increase in LP I h G max and a priming event that permitted calcineurin regulation of LP I h. The latter produced graded reductions in LP I hG max with increasing duty cycles. We also demonstrated that this metamodulation preserved the timing of LP's first spike when network output was perturbed with bath-applied 4AP. In sum, 5nM DA permits slow wave activity to provide feedback that maintains spike timing, suggesting that one function of low-level, tonic modulation is to stabilize specific features of a dynamic output.

Um láser de CO2, trabalhando no modo contínuo, foi utilizado para produzir um traço refundido sobre a superfície de um ferro fundido branco em intervalos de velocidade de varredura do feixe entre 0,01 e 1,00 cm/s. O registro da temperatura em função do tempo foi realizada por três termopares fixados à superfície inferior da amostra. Verificou-se que cerva de 13 % da radiação incidente sobre a superfície da amostra é absorvida em forma de calor, para um feixe com 0,65 mm de diâmetro, idependentemente da velocidade de varredura do feixe. No caso do feixe com diâmetro de 1,11 mm, a absorção cai para cerca de 11 %.

Light U(1) gauge boson coupled to baryon number
International Nuclear Information System (INIS)
Carone, C.D.; Murayama, Hitoshi
1995-06-01
The authors discuss the phenomenology of a light U(1) gauge boson, γ B , that couples only to baryon number. Gauging baryon number at high energies can prevent dangerous baryon-number violating operators that may be generated by Planck scale physics. However, they assume at low energies that the new U(1) gauge symmetry is spontaneously broken and that the γ B mass m B is smaller than m z . They show for m Υ B z that the γB coupling α B can be as large as ∼ 0.1 without conflicting with the current experimental constraints. The authors argue that α B ∼ 0.1 is large enough to produce visible collider signatures and that evidence for the γ B could be hidden in existing LEP data. They show that there are realistic models in which mixing between the γ B and the electroweak gauge bosons occurs only as a radiative effect and does not lead to conflict with precision electroweak measurements. Such mixing may nevertheless provide a leptonic signal for models of this type at an upgraded Tevatron

In skeletal muscle, the actin cytoskeleton-regulating GTPase, Rac1, is necessary for insulin-dependent GLUT4 translocation. Muscle contraction increases glucose transport and represents an alternative signaling pathway to insulin. Whether Rac1 is activated by muscle contraction and regulates contraction-induced glucose uptake is unknown. Therefore, we studied the effects of in vivo exercise and ex vivo muscle contractions on Rac1 signaling and its regulatory role in glucose uptake in mice and humans. Muscle Rac1-GTP binding was increased after exercise in mice (∼60–100%) and humans (∼40%), and this activation was AMP-activated protein kinase independent. Rac1 inhibition reduced contraction-stimulated glucose uptake in mouse muscle by 55% in soleus and by 20–58% in extensor digitorum longus (EDL; P Rac1 knockout mice. Furthermore, depolymerization of the actin cytoskeleton decreased contraction-stimulated glucose uptake by 100% and 62% (P Rac1 is activated during muscle contraction in murine and human skeletal muscle and suggest that Rac1 and possibly the actin cytoskeleton are novel regulators of contraction-stimulated glucose uptake.

Talmi, Igal
2005-01-01
A recursion formula for the number of states with a given value of total spin J of n identical fermions in a j orbit, N(J,j,n), is derived. That number is expressed in terms of the number of states with some values of J, of n,n-1, and n-2 fermions in a (j-1) orbit. This formula may be used in calculating N(J,j,n). In this paper the formula is used to prove some interesting results that were found empirically by Zhao and Arima

The n-Cu0.9Ag0.1In3Se5 chalcopyrite, electronic as well as ionic conductor
International Nuclear Information System (INIS)
Diaz, R
2008-01-01
A resistance increase with time of the n-Cu 0.9 Ag 0.1 In 3 Se 5 chalcopyrite has been observed. This new effect is analysed in terms of a hypothesis of ion migration and Schottky barrier formation. These results might explain why different solar cell efficiencies are obtained for the chalcopyrites, CuInSe 2 and CuIn x Ga 1-x Se 2 , when an In-rich film is deposited on top of the chalcopyrite. In these solar cells, ion migration can exist and a new effect appears similar to the one observed in our compound. The ions, probably the cations, are moved by the electrical field towards the cathode. A gradient of mobile ions appears across the sample and the positive charge is accumulated near this electrode such that it varies the metal-semiconductor interface. This interface is a Schottky barrier where the contact potential is a function of time due to the arrival of ions. The electrical measurements have been carried out on a solid state device, graphite/n-Cu 0.9 Ag 0.1 In 3 Se 5 /graphite. The current intensity and the potential drop across the sample have been measured with time when a constant electrical potential is applied for 600 s at dark or under ultraviolet illumination and at room temperature. A comparative study in similar electrical conditions is done; the current intensity difference and the potential drop across the difference (under ultraviolet illumination minus at dark) are not constant and both measurements increase with time

Purpose: Four-dimensional computed tomography (4DCT) can be used to evaluate longitudinal changes in pulmonary function. The sensitivity of such measurements to identify function change may be improved with reproducible breathing patterns. The purpose of this study was to determine if inhale was more consistent than exhale, i.e., lung expansion during inhalation compared to lung contraction during exhalation. Methods: Repeat 4DCT image data acquired within a short time interval from 8 patients. Using a tissue volume preserving deformable image registration algorithm, Jacobian ventilation maps in two scanning sessions were computed and compared on the same coordinate for reproducibility analysis. Equivalent lung volumes (ELV) were used for 5 subjects and equivalent title volumes (ETV) for the 3 subjects who experienced a baseline shift between scans. In addition, gamma pass rate was calculated from a modified gamma index evaluation between two ventilation maps, using acceptance criterions of 2mm distance-to-agreement and 5% ventilation difference. The gamma pass rates were then compared using paired t-test to determine if there was a significant difference. Results: Inhalation was more reproducible than exhalation. In the 5 ELV subjects 78.5% of the lung voxels met the gamma criteria for expansion during inhalation when comparing the two scans, while significantly fewer (70.9% of the lung voxels) met the gamma criteria for contraction during exhalation (p = .027). In the 8 total subjects analyzed the average gamma pass rate for expansion during inhalation was 75.2% while for contraction during exhalation it was 70.3%; which trended towards significant (p = .064). Conclusion: This work implies inhalation is more reproducible than exhalation, when equivalent respiratory volumes are considered. The reason for this difference is unknown. Longitudinal investigation of pulmonary function change based on inhalation images appears appropriate for Jacobian-based measure of

Pacta sunt servanda versus the social role of contracts: the case of Brazilian agriculture contracts
Directory of Open Access Journals (Sweden)

Full Text Available This study explores the instability created by contradictory court decisions related with contract breaches. Forward marketing contracts represent an important source of resources to finance Brazilian agriculture, however a large number of contract breaches were observed during a period of marked increase in soy prices. The study analyzed 161 judicial appeal decisions and a survey was carried with 70 farmers. The results show the difference of judges' interpretation and the existence of second order effects. The effects of court decisions were more requirements of guarantees and the reduction in the number of contracts. Those soybean farmers who did not breach their contracts have also been negatively affected by the strategic reactions of trading and processing companies. The concept of "social function of the contract" introduced in Brazilian civil code led to a higher degree of instability in contracts, raising transaction costs and motivating private economic sanctions.

A partir da determinação confiável do conteúdo de água no solo na capacidade de campo, pode-se otimizar a produtividade das culturas agrícolas, maximizando a eficiência do uso da água pelas plantas e evitando a contaminação do lençol freático por lixiviação de fertilizantes e agroquímicos. Nesse sentido, o trabalho teve como objetivo avaliar a capacidade de campo (a pelo cálculo da densidade de fluxo da água durante o processo de redistribuição no experimento clássico de determinação desse parâmetro e (b a partir de uma dada tensão da água na curva de retenção, em um Latossolo Vermelho-Amarelo textura média, localizado em área experimental da Escola Superior de Agricultura Luiz de Queiroz, município de Piracicaba, Estado de São Paulo (Brasil.

Thermal expansion and magnetostriction of members of a homologous series of compounds based on the alloy series Pr (n+2)(n+1) Ni n(n-1)+2 Si n(n+1) have been measured. The crystal structures of these compounds are closely interrelated because they form trigonal prismatic columns in which the number of trigonal prisms that form the base of the trigonal columns is determined by the value of n in the chemical formula. Two compositions were investigated, Pr 5 Ni 2 Si 3 and Pr 15 Ni 7 Si 10 , corresponding to n=3 and n=4, respectively. The results were analyzed and used to determine the location of magnetic phase transitions by calculating the magnetic contribution to thermal expansion using the Gruneisen-Debye theory. This allowed more precise determination of the magnetic transition temperatures than could be achieved using the total thermal expansion. The results show two phase transitions in each material, one corresponding to the Curie temperature and the other at a lower temperature exhibiting characteristics of a spin reorientation transition

Full Text Available JUSTIFICATIVA E OBJETIVOS: A potencialização da procainamida sobre o bloqueio neuromuscular produzido pela d-tubocurarina já está comprovada, porém o mecanismo é controverso. O objetivo do estudo foi avaliar a influência da procainamida no bloqueio neuromuscular produzido pelo rocurônio e investigar os mecanismos desta interação. MÉTODO: Foram utilizados 15 ratos (250 a 300 g em preparação descrita por Bülbring. Formaram-se os seguintes grupos (n = 5 cada: procainamida - 20 µg.mL-1 (Grupo I; rocurônio - 4 µg.mL-1 (Grupo II e rocurônio - 4 µg.mL-1 e procainamida - 20 µg.mL-1 (Grupo III. Avaliaram-se: 1 a amplitude das contrações musculares sob estimulação indireta em cada grupo, antes e após a adição dos fármacos; 2 os potenciais de placa terminal em miniatura (PPTM; 3 a eficácia da 4-aminopiridina na reversão do bloqueio neuromuscular. O mecanismo da interação foi estudado em Biventer cervicis (n = 5 e diafragma de rato desnervado (n = 5, observando-se a influência da procainamida na resposta à acetilcolina antes e após a adição da procainamida. RESULTADOS: A procainamida isoladamente não alterou as respostas neuromusculares. O bloqueio produzido com o Grupo III foi de 68,6% ± 7,1%, com diferença significativa (p = 0,0067 em relação ao Grupo II (10,4% ± 4,5%, revertido pela 4-aminopiridina. A procainamida ocasionou aumento na freqüência dos PPTM, seguido de bloqueio revertido pela 4-aminopiridina. Em Biventer cervicis a procainamida aumentou a resposta à ação de contração da acetilcolina, resultado não observado com o diafragma desnervado. CONCLUSÕES: A procainamida potencializou o bloqueio produzido pelo rocurônio. As alterações observadas com PPTM e Biventer cervicis identificaram ação pré-sináptica. O antagonismo da 4-aminopiridina sobre o bloqueio dos PPTM sugeriu dessensibilização dos receptores pela procainamida.JUSTIFICATIVA Y OBJETIVOS: La potenciación de la procainamida sobre
Debt renegotiation with incomplete contract

Full Text Available A debt contract usually does not include a provision about renegotiation. The right to seize the borrower’s asset and the rules of this process are usually stipulated in the contract. Such a promise not to renegotiate is not credible since renegotiation can mitigate the dead-weight loss of liquidating insolvent borrowers. Once the initial contract may not consider the renegotiation procedure and renegotiation may occur, this paper investigates why a complete contract is not offered. It shows that the lender does not need to stipulate the renegotiation procedure on the initial contract because he is indifferent about committing or not to the terms of a contract. This indicates that a complete contract gives the lender the same expected return as an incomplete contract, in which the renegotiation process is determined after the occurrence of default.Um contrato de débito geralmente não inclui uma cláusula sobre renegociação. O direito de liquidar os ativos do tomador e as regras do processo são habitualmente estipuladas no contrato. Tal promessa de não renegociar não é crível, já que a renegociação pode mitigar a perda bruta de se liquidar tomadores insolventes. Uma vez que o contrato inicial pode não considerar os procedimentos de renegociação, e esta pode, de fato, vir a ocorrer, este artigo investiga a razão de um contrato completo não ser ofertado. Mostra-se que o emprestador não precisa estipular os procedimentos de renegociação no contrato inicial porque ele é indiferente entre se comprometer ou não aos termos do contrato. Isto indica que um contrato completo dá ao emprestador o mesmo retorno esperado de um contrato incompleto, no qual os procedimentos de renegociação são determinados após a declaração de default.

This study describes the development of a new questionnaire to measure health-related quality of life (HRQoL) in patients with type 1 diabetes (the ViDa1 questionnaire) and provides information on its psychometric properties. For its development, open interviews with patients took place and topics relevant to patients' HRQoL were identified and items were generated. Qualitative analysis of items, expert review, and refinement of the questionnaire followed. A pilot study (N = 150) was conducted to explore the underlying structure of the 40-item ViDa1 questionnaire. A Principal Component Analysis (PCA) was performed and six of the items that did not load on any of the factors were eliminated. The results supported a four-dimensional structure for ViDa1, the dimensions being Interference of diabetes in everyday life, Self-care, Well-being, and Worry about the disease. Subsequently, the PCA was repeated in a larger sample (N = 578) with the reduced 34-item version of the questionnaire, and a Confirmatory Factor Analysis (CFA) was performed (N = 428). Overall fit indices obtained presented adequate values which supported the four-factor model initially proposed [(χ(df=554)2= 2601.93) (p diabetes and low correlations with other constructs such as self-efficacy, anxiety, and depression were presented. The ViDa1 also discriminated between different aspects of clinical interest such as type of insulin treatment, presence of chronic complications, and glycemic control, temporal stability, and sensitivity to change after an intervention. In conclusion, the ViDa1 questionnaire presents adequate psychometric properties and may represent a good alternative for the evaluation of HRQoL in type 1 diabetes. PMID:28620331

Full Text Available As doenças cardiovasculares constituem uma das principais causas de mortes em todo o mundo. Estudos mostram que a enzima HMG-CoA é considerada uma precursora da via metabólica hipolipidêmica no soro sanguíneo. Na busca por uma nova classe de compostos aptos a inibir esta enzima e consequentemente reduzir os níveis de colesterol, as 2-fenilindano-1,3-dionas apresentam resultados promissores. Uma das maneiras de avaliar o poder farmacológico destes compostos e predizer análogos ainda mais potentes consiste na avaliação da interação entre fármaco (2-fenilindano-1,3-diona e enzima (HMG-CoA, em que se utiliza da técnica de modelagem molecular docking. Neste estudo, o procedimento computacional para obtenção dos resultados de docking foi feito através do software AutoDock 1.5.6. Para avaliar a interação no sítio ativo da HMG-CoA, utilizamos, dentre a série de congêneres, o composto 2-(2-clorofenilindano-1,3-diona. De acordo com os resultados obtidos, foi identificada uma interação hidrofílica importante, do tipo ligação de hidrogênio C=O∙∙∙H–N, a qual apresenta uma distância de 1.62 Å entre os grupos carbonila do anel diona e o aminoácido metionina da HMG-CoA. Outra ligação de hidrogênio p∙∙∙H–N com distância de 3.10 Å formada entre o anel aromático do grupo indano-1,3-diona e o aminoácido glicina também foi identificada.

To evaluate the repeatability of (Motor Unit Number Index) MUNIX under repeatability conditions, specify the origin of variations and provide strategies for quality control. MUNIX calculations were performed on the bicep brachii muscles of eight healthy subjects. Negative effect of suboptimal electrode positions on MUNIX accuracy was eliminated by employing the high-density surface electromyography technique. MUNIX procedures that utilized a variety of surface interferential pattern (SIP) epoch recruitment strategies (including the original MUNIX procedure, two proposed improvement strategies and their combinations) were described. For each MUNIX procedure, ten thousands of different SIP pools were constructed by randomly recruiting necessary SIP epochs from a large SIP epoch pool (3 datasets, 9 independent electromyography recordings at different contraction levels per dataset and 10 SIP epochs per recording) and implemented for MUNIX calculation. The repeatability of each MUNIX procedure was assessed by summarizing the resulting MUNIX distribution and compared to investigate the effect of SIP epoch selection strategy on repeatability performance. SIP epochs selected at lower contraction levels have a stronger influence on the repeatability of MUNIX than those selected at higher contraction levels. MUNIX under repeatability conditions follows a normal distribution and the standard deviation can be significantly reduced by introducing more epochs near the MUNIX definition line. The MUNIX technique shows an inherent variation attributable to SIP epochs at low contraction levels. It is recommended that more epochs should be sampled at these low contraction levels to improve the repeatability. The present study thoroughly documented the inherent variation of MUNIX and the causes, and offered practical solutions to improve the repeatability of MUNIX.

Full Text Available América Latina es actualmente la región con mayor tasa de homicidios a nivel mundial, y gran parte de los asesinatos están vinculados al denominado crimen organizado, especialmente al narcotráfico. El narcotráfico es producto de la ilegalización de ciertas sustancias, la cual -por lo menos en la actualidad- está basada y legitimada en criterios biomédicos que convierten la producción, comercialización y frecuentemente el consumo de ciertas sustancias consideradas adictivas en "delitos contra la salud". En este texto se analizan en forma sucinta las dos políticas formuladas y aplicadas hasta ahora en términos prohibicionistas y de reducción de daños, considerando el fracaso del prohibicionismo, así como las limitaciones de las propuestas de reducción de daños. Respecto del prohibicionismo se señalan sus múltiples y constantes incongruencias y contradicciones, lo cual implica que tomemos con cautela los reiterados señalamientos sobre su "fracaso". El texto propone la aplicación de una política de reducción de riesgos que incluya no solo los comportamientos de sujetos y grupos, sino también la dimensión estructural tanto en términos económico-políticos como culturales.
Rac1--a novel regulator of contraction-stimulated glucose uptake in skeletal muscle.
Sylow, Lykke; Møller, Lisbeth L V; Kleinert, Maximilian; Richter, Erik A; Jensen, Thomas E
2014-12-01
Muscle contraction stimulates muscle glucose uptake by facilitating translocation of glucose transporter 4 from intracellular locations to the cell surface, which allows for diffusion of glucose into the myofibres. The intracellular mechanisms regulating this process are not well understood. The GTPase Rac1 has, until recently, been investigated only with regard to its involvement in insulin-stimulated glucose uptake. However, we recently found that Rac1 is activated during muscle contraction and exercise in mice and humans. Remarkably, Rac1 seems to be necessary for exercise and contraction-stimulated glucose uptake in skeletal muscle, because muscle-specific Rac1 knockout mice display reduced ex vivo contraction- and in vivo exercise-stimulated glucose uptake. The molecular mechanism by which Rac1 regulates glucose uptake is presently unknown. However, recent studies link Rac1 to the actin cytoskeleton, the small GTPase RalA and/or free radical production, which have previously been shown to be regulators of glucose uptake in muscle. We propose a model in which Rac1 is activated by contraction- and exercise-induced mechanical stress signals and that Rac1 in conjunction with other signalling regulates glucose uptake during muscle contraction and exercise. © 2014 The Authors.

The present paper reports the determination of the tri-amine N-(3-aminopropyl)-N-dodecyl-1,3-propanediamine (TA) present in a raw material called LONZABAC used to formulate various, widely used commercial biocides. The active principle, TA, is present in LONZABAC together with other molecules at lower concentration levels. Three independent analytical approaches, namely solution NMR spectroscopy, liquid chromatography coupled to high resolution mass spectrometry (LC/HRMS) and acid-base titration in mixed solvent, were used to overcome the problem of the non-availability of the active principle as high purity standard. NMR analysis of raw material, using a suitable internal standard, evidenced in all analyzed lots the presence of the active principle, the N-dodecyl-1,3-propanediamine (DA) and the n-dodecylamine (MA) and the absence of non-organic, NMR-inactive species. NMR peak integration led to a rough composition of the MA:DA:TA as 1:9:90. The LC/HRMS analysis allowed the accurate determination of DA and MA and confirmed in all samples the presence of the TA, which was estimated by difference: MA=1.4±0.3%, DA=11.1±0.7%, TA=87.5±1.3%. The obtained results were used to setup an easy, rapid and cheap acid-base titration method able to furnish a sufficiently accurate evaluation of the active principle both in the raw material and in diluted commercial products. For the raw material the results were: TA+MA=91.1±0.8% and DA-MA=8.9±0.8%, statistically coherent with LC/MS ones. The LC/MS approach demonstrated also its great potentialities to recognize trace of the biocide components both in environmental samples and in the formulated commercial products.

Ultrasound elastography is used to assess muscle hardness or stiffness; however, no previous studies have validated muscle hardness measures using ultrasound strain elastography (SE). This study investigated the relationship between plantar flexor isometric contraction intensity and gastrocnemius hardness assessed by SE. We hypothesised that the muscle would become harder linearly with an increase in the contraction intensity of the plantar flexors. Fifteen young women (20.1 ± 0.8 years) performed isometric contractions of the ankle plantar flexors at four different intensities (25, 50, 75, 100% of maximal voluntary contraction force: MVC) at 0° plantar flexion. Using SE images, the strain ratio (SR) between the muscle and an acoustic coupler (elastic modulus 22.6 kPa) placed over the skin was calculated (muscle/coupler); pennation angle and muscle thickness were measured for the resting and contracting conditions. SR decreased with increasing contraction intensity from rest (1.28 ± 0.20) to 25% (0.99 ± 0.21), 50% (0.61 ± 0.15), 75% (0.34 ± 0.1) and 100% MVC (0.20 ± 0.05). SR decreased linearly (P < 0.05) with increasing MVC from rest to 75% MVC, but levelled off from 75 and 100% MVC. SR was negatively correlated with pennation angle (r = -0.80, P < 0.01) and muscle thickness ( r= -0.78, P< 0.01). SR appears to represent muscle hardness changes in response to contraction intensity changes, in the assumption that the gastrocnemius muscle contraction intensity is proportional to the plantar flexion intensity. We concluded that gastrocnemius muscle hardness changes could be validly assessed by SR, and the force-hardness relationship was not linear.

Full Text Available RESUMO: O papel da N-acetilcesteína (NAC no tratamento da bronquite crónica não está estabelecido.Dado que vários estudos foram publicados sobre este assunto, os autores propuseram-se fazer uma revisão sistematizada de alguns desses estudos.Efectuaram a revisão de ensaios randomizados comparando a NAC oral com placebo em doentes com doença pulmonar obstrutiva crónica (DPOC. Foram pesquisados artigos publicados em diversas línguas, em Medline, Embase e Cochrane Library.Onze artigos envolvendo 2011 doentes preen-cheram os critérios de selecção.O tratamento com NAC consistia em terapêutica oral de 400 a 600 mg por dia sendo a duração superior a 3 meses na maioria dos estudos. Os factores de risco de exacerbação bem como a caracterização da gravidade da DPOC através do estudo funcional não foram avaliados em todos os estudos.O papel da NAC na redução do número de exacerbações foi avaliado em 9 dos 11 estudos, sendo exacerbação definida como o aumento da tosse, da expectação mucopurulenta e/ou dispneia. Os resultados mostraram que 48,5% dos doentes medicados com NAC (351 de 723 não tiveram exacerbações comparativamente com 31,2% dos doentes sob placebo (229 de 733. O benefício relativo da NAC foi de 1,56.Em 5 estudos foram usadas escalas de auto-avaliação do tratamento, sendo possível seleccionar os doentes que referiam melhoria dos seus sintomas, o que se verificou em 61,4% dos doentes medicados com NAC (286 de 466 comparativamente a 34,6% dos doentes sob placebo (160 de 462. O benefício relativo da NAC foi de 1,78.Em relação aos efeitos adversos, 6 estudos relataram queixas gastrointestinais que se repartiram por 68 em 666 (10,2% dos doentes tratados com NAC, comparativamente a 73 em 671 (10,9% dos doentes medicados com placebo.Alguns estudos analisaram outras variáveis. Num estudo com DPOC grave o FEV1 melhorou significativamente nos doentes tratados com NAC, embora o ensaio decorresse em apenas 4 semanas

Full Text Available This study describes the development of a new questionnaire to measure health-related quality of life (HRQoL in patients with type 1 diabetes (the ViDa1 questionnaire and provides information on its psychometric properties. For its development, open interviews with patients took place and topics relevant to patients' HRQoL were identified and items were generated. Qualitative analysis of items, expert review, and refinement of the questionnaire followed. A pilot study (N = 150 was conducted to explore the underlying structure of the 40-item ViDa1 questionnaire. A Principal Component Analysis (PCA was performed and six of the items that did not load on any of the factors were eliminated. The results supported a four-dimensional structure for ViDa1, the dimensions being Interference of diabetes in everyday life, Self-care, Well-being, and Worry about the disease. Subsequently, the PCA was repeated in a larger sample (N = 578 with the reduced 34-item version of the questionnaire, and a Confirmatory Factor Analysis (CFA was performed (N = 428. Overall fit indices obtained presented adequate values which supported the four-factor model initially proposed [(χ(df=5542= 2601.93 (p < 0.001; Root Mean Square Error of Approximation = 0.060 (CI = 0.056 −0.064]. As regards reliability, the four dimensions of the ViDa1 demonstrated good internal consistency, with Cronbach's alphas ranging between 0.71 and 0.86. Evidence of convergent-discriminant validity in the form of high correlations with another specific HRQoL questionnaire for diabetes and low correlations with other constructs such as self-efficacy, anxiety, and depression were presented. The ViDa1 also discriminated between different aspects of clinical interest such as type of insulin treatment, presence of chronic complications, and glycemic control, temporal stability, and sensitivity to change after an intervention. In conclusion, the ViDa1 questionnaire presents adequate psychometric

Full Text Available Objetivo: avaliar a relação entre alterações das contrações uterinas e parto prematuro. Metodologia: entre fevereiro de 1996 e junho de 1998, 73 gestantes com risco para o parto prematuro foram submetidas à monitorização externa das contrações uterinas, da 24ª à 34ª semana de gestação, duas vezes por semana, durante 60 minutos. O teste foi considerado positivo quando as contrações uterinas apresentavam freqüência maior ou igual a 4 contrações/hora antes da 30ª semana e a 6 contrações/hora após esta data. Resultado: foram excluídas da análise 17 pacientes (23,28% por apresentarem patologias obstétricas ou evolução desfavorável para os resultados finais. Das 56 gestantes restantes, a incidência de partos prematuros espontâneos foi de 23,21% (13/56. A freqüência média das contrações uterinas foi significativamente maior no grupo que evoluiu para o parto prematuro. O método revelou uma sensibilidade de 69,23%, uma especificidade de 86,04% e valores preditivos positivo e negativo de 60% e 90,24%, respectivamente. Conclusão: o teste negativo está associado a baixo risco de nascimento prematuro. Contudo, diante do teste positivo, torna-se necessária a associação com outros marcadores do parto prematuro para melhor identificar pacientes com risco elevado.Purpose: to evaluate the relationship between uterine contractions and premature delivery.

Full Text Available Introducción En modelos experimentales, la formación de especies reactivas del oxígeno durante la reperfusión posisquémica induce “estrés oxidativo” que afecta al miocardio. Dado que los pacientes sometidos a cardioplejía sufren isquemia-reperfusión, se sugirió que en ellos habría estrés oxidativo. Sin embargo, este fenómeno aún no se ha caracterizado correctamente. Objetivo El propósito del presente trabajo fue correlacionar la liberación de glutatión (el paso inicial de estrés oxidativo con marcadores de progresión del daño oxidativo, como peroxidación de lípidos de membrana y desarrollo de alteraciones ultraestructurales. Material y métodos En 24 pacientes sometidos a cirugía de puente aortocoronario se investigaron cambios en varios marcadores de estrés oxidativo y daño tisular durante la reperfusión posisquémica. Se obtuvieron muestras de sangre y biopsias cardíacas basales y luego de la reperfusión a 40,9 ± 11,9 minutos de la cardioplejía. La liberación de glutatión basal fue insignificante (0,02 ± 0,04 µmol/L, pero aumentó a los 15 minutos de la reperfusión (1,10 ± 0,40 µmol/L; p < 0,05; también disminuyeron los niveles tisulares de ubiquinol, de 144,5 ± 52 a 97,6 ± 82 nmol/g (p < 0,05. Aunque estos cambios documentan el estrés oxidativo cardíaco, no hubo alteraciones bioquímicas indicativas de daño celular, ya que no se produjo un incremento de marcadores de peroxidación lipídica, tanto en sangre del seno coronario como en las biopsias cardíacas. Tampoco se observaron alteraciones ultraestructurales importantes. Conclusiones A pesar de observarse estrés oxidativo en pacientes sometidos a cirugía cardíaca, en las condiciones descriptas, no induce lesiones progresivas de membranas ni daño celular irreversible

Particle Number Dependence of the N-body Simulations of Moon Formation
Sasaki, Takanori; Hosono, Natsuki
2018-04-01
The formation of the Moon from the circumterrestrial disk has been investigated by using N-body simulations with the number N of particles limited from 104 to 105. We develop an N-body simulation code on multiple Pezy-SC processors and deploy Framework for Developing Particle Simulators to deal with large number of particles. We execute several high- and extra-high-resolution N-body simulations of lunar accretion from a circumterrestrial disk of debris generated by a giant impact on Earth. The number of particles is up to 107, in which 1 particle corresponds to a 10 km sized satellitesimal. We find that the spiral structures inside the Roche limit radius differ between low-resolution simulations (N ≤ 105) and high-resolution simulations (N ≥ 106). According to this difference, angular momentum fluxes, which determine the accretion timescale of the Moon also depend on the numerical resolution.

Foram utilizados nove tratamentos decorrentes da combinação dos potenciais mínimos de água no solo de -0,05, -0,20 e -1,50 MPa, com os estádios fenológicos de máximo perfilhamento, florescimento e grão leitoso, permanecendo uniformizados durante o restante do ciclo, entre os potenciais de -0,01 a -0,05 MPa. Os resultados de produção, peso e teor de proteína dos grãos, tamanho de espigas, número total e número de espigas chochas, mostraram que os efeitos de défices hídricos variaram com a intensidade, duração e estádio fenológico da cultura, onde o estádio de florescimento mostrou-se mais sensível ao défice de água. A ocorrência de défice hídrico intenso, em cada um dos estádios, bem como ciclos repetidos de défices moderados ou intensos, levaram à diminuições significativas na produção de grãos, além de ocorrer tendência ao aumento do teor de protema dos grãos. O manejo da irrigação na cultura da cevada, quando se busca a máxima eficiência no uso da água, deve levar em conta os diferentes estádios fenológicos.The experiment was carried out under greenhouse conditions, with the objective of evaluating the effects of water deficits in three phenological phases of barley crop (Hordeum vulgare L..

Full Text Available Na literatura, há controvérsias sobre a importância da massa corporal total (MCT, da massa magra (MM e da massa gorda (MG como determinantes da densidade mineral óssea (DMO em mulheres idosas. OBJETIVOS: Determinar a relação da DMO com a MCT, MM e MG em mulheres idosas. MÉTODOS: Foram estudadas 97 mulheres com idade entre 60-70 anos e média de 66,41 ± 4,82 anos. Nenhuma participante fazia uso de hormônios ou qualquer outro medicamento que pudesse afetar o metabolismo ósseo, assim como não tinham o hábito de fumar ou de ingerir bebidas alcoólicas. A composição corporal e a DMO do colo femoral (CF e da coluna lombar (CL foram medidas através da DXA, um DPX-IQ lunar. As relações entre MCT, MM e MG e a DMO do CF e da CL foram realizadas separadamente, através da análise de regressão linear. A análise de regressão múltipla foi utilizada para determinar a contribuição da MCT, MM e MG sobre a DMO do CF e da CL. RESULTADOS: A MCT mostrou-se fortemente correlacionada com a DMO do CF e da CL (r = 0,54, p = 0,01 e r = 0,37, p = 0,01, respectivamente, do que a MG (r = 0,30, p = 0,01 e r = 0,19, p = 0,06, respectivamente e MM (r = 0,44, p = 0,01 e r = 0,26, p = 0,05, respectivamente. CONCLUSÃO: A MCT e a MM foram os componentes corporais que mantiveram relação significativa com a DMO do CF e da CL. A MG mostrou correlação fraca com a DMO do CF e da CL, não sendo estatisticamente significativa neste último sítio. Assim, a MCT e a MM são, entre as variáveis da composição corporal, as que mais significativamente determinam a DMO em mulheres idosas.En la literatura, hay controversias sobre la importancia de la masa corporal total (MCT, la masa magra (MM, y la masa grasa (MG como decisivas sobre la estimación de la densidad mineral osea (DMO en las mujeres mayores.

Full Text Available We studied the primary and secondary esophageal peristalsis in 36 patients with heartburn and acid regurgitation and in 14 asymptomatic volunteers. Primary peristalsis was elicited by ten swallows of a 5-mL bolus of water and secondary peristalsis was elicited by intra-esophageal infusion of 5, 10, and 15 mL water, 0.1 N hydrochloric acid and air. Esophageal contractions were measured by an 8-lumen manometric catheter assembly incorporating a 6-cm sleeve device. Contractions were registered at 3, 9, and 15 cm from the upper margin of the sleeve and the infusion was done through a side hole located at 12 cm. Twenty patients had normal endoscopic esophageal examination, 10 with normal (group I and 10 with abnormal pH-metric examination (group II, and 16 had esophagitis (group III. The amplitude of contractions after swallows was lower (97.8 ± 10.0 mmHg in the distal esophagus of group III patients than in controls (142.3 ± 14.0 mmHg. Patients of group III had fewer secondary contractions (water: 25% of infusion than patients of the other groups and controls (67% of infusion. Patients of group III also had a lower amplitude of secondary peristalsis in the distal esophagus (water: 70.1 ± 9.6 mmHg than controls (129.2 ± 18.2 mmHg. We conclude that patients with esophagitis have an impairment of primary and secondary peristalsis in the distal esophagus.

Methods : Thirty-two admitted patients with H1N1 pneumonia were enrolled in the study. The clinical profiles, humoral and cell-mediated immune responses of the 16 H1N1 pneumonia patients who were admitted to the pediatric intensive care unit (severe pneumonia group, 16 H1N1 pneumonia patients admitted to the pediatric general ward (moderate pneumonia group and 13 control subjects (control group were measured. Results : Total lymphocyte counts were significantly lower in patients with H1N1 pneumonia than in the control group (P=0.02. The number of CD4+ T lymphocytes was significantly lower in the severe pneumonia group (411.5±253.5/μL than in the moderate pneumonia (644.9±291.1/μL, P=0.04 and control (902.5±461.2/μL, P=0.01 groups. However, the number of CD8+ T lymphocytes was significantly higher in the severe pneumonia group (684.2±420.8/μL than in the moderate pneumonia (319.7±176.6/μL, P=0.02 and control (407.2±309.3/μL, P=0.03 groups. The CD4+/CD8+ T lymphocytes ratio was significantly lower in the severe pneumonia group (0.86±0.24 than in the moderate pneumonia (1.57±0.41, P=0.01 and control (1.61±0.49, P=0.01 groups. The serum levels of immunoglobulin G, immunoglobulin M and immunoglobulin E were significantly higher in the severe pneumonia group than in the 2 other groups. Conclusion : The results of this study suggest that increased humoral immune responses and the differences in the CD4+ and CD8+ T lymphocyte profiles, and imbalance of their ratios may be related to the severity of H1N1 pneumonia in children.

Full Text Available A pesquisa teve a finalidade de determinar o número relativo de radicais livres e a dureza Knoop de três resinas compostas (Z100, Silux Plus e Heliomolar RO. Para o ensaio dos radicais livres, as irradiações foram: 110, 180, 300, 580 mW/cm2, pelos tempos de 10, 20, 30, 40, 50, 60, 80 e 90 segundos. As durezas foram determinadas com as cores claras com irradiação de 110 e 300 mW/cm2, por 20, 40, 60 e 80 segundos, nas faces da frente e do fundo, nas idades de 5 minutos, 1 hora, 1 dia, 1 semana e 1 mês. As conclusões foram: a resina Z100 apresentou cerca de 3 vezes mais radicais livres do que as outras; o número relativo de radicais livres aumenta com a intensidade e tempo de exposição; maior intensidade de luz aumentou a dureza; maior tempo de exposição aumentou as durezas das resinas Silux Plus e Heliomolar, mas não da Z100; a dureza aumentou com a idade até 1 mês; o lado da irradiação apresentou maior dureza do que o do fundo; a resina Z100 foi bem mais dura e sofreu menos a influência da irradiação.The present study had the purpose of determining the relative number of free radicals of three composites with clear and dark colors. Intensities of irradiation were: 110, 180, 300, and 580 mW/cm2, for 10, 20, 30, 40, 50, 60, 80 and 90 seconds. Hardness was determined for the clear colors of the composites, using 110 and 300 mW/cm2 irradiation intensities, for 20, 40, 60, and 80 seconds, on front and deep surfaces, at the ages of 5 minutes, 1 hour, 1 day, 1 week, and 1 month. The conclusions were that: depending on the resin, clear colors present more free radicals; the number of free radicals increases with higher intensity and longer irradiation time; composite Z100 is much richer in free radicals than Silux Plus and Heliomolar RO; higher intensity of irradiation leads to increasing hardness; longer irradiation time increases hardness of Silux Plus and Heliomolar RO, but not that of Z100; hardness increases with age; in depth
Sorting Real Numbers in $O(n\\sqrt{\\log n})$ Time and Linear Space

We present an $O(n\\sqrt{\\log n})$ time and linear space algorithm for sorting real numbers. This breaks the long time illusion that real numbers have to be sorted by comparison sorting and take $\\Omega (n\\log n)$ time to be sorted.

Full Text Available OBJETIVO: Avaliar a eficiência da radiação ionizante por 60CO na eliminação de Vibrio cholerae O1, El Tor Ogawa, não-toxigênico, incorporados laboratorialmente em ostras vivas da espécie Crassostrea brasiliana. MÉTODO: Foram selecionadas amostras de ostras provenientes de Cananéia (litoral sul de São Paulo, Brasil, as quais foram contaminadas com Vibrio cholerae e irradiadas com doses de 0,5 kGy e 1,0 kGy. RESULTADOS: Foram observadas diminuições significativas do número inicial do microrganismo indicado: de 3,4.10(7 para 10³ e 10², respectivamente. Os valores de D10 correspondentes foram de 0,173 a 0,235. CONCLUSÃO: Adotando-se o fator 6 como nível de segurança, conclui-se que a dose de irradiação de 1,41 kGy é necessária para eliminar números elevados de células viáveis de V. cholerae em ostras. Os experimentos foram realizados com os controles respectivos.

The broadly neutralizing antibody (bNAb) VRC01, capable of neutralizing 91% of known human immunodeficiency virus type 1 (HIV-1) isolates in vitro , is a promising candidate microbicide for preventing sexual HIV infection when administered topically to the vagina; however, accessibility to antibody-based prophylactic treatment by target populations in sub-Saharan Africa and other underdeveloped regions may be limited by the high cost of conventionally produced antibodies and the limited capacity to manufacture such antibodies. Intravaginal rings of the pod design (pod-IVRs) delivering Nicotiana -manufactured VRC01 (VRC01-N) over a range of release rates have been developed. The pharmacokinetics and preliminary safety of VRC01-N pod-IVRs were evaluated in a rhesus macaque model. The devices sustained VRC01-N release for up to 21 days at controlled rates, with mean steady-state VRC01-N levels in vaginal fluids in the range of 10 2 to 10 3 μg g -1 being correlated with in vitro release rates. No adverse safety indications were observed. These findings indicate that pod-IVRs are promising devices for the delivery of the candidate topical microbicide VRC01-N against HIV-1 infection and merit further preclinical evaluation.

Full Text Available CONTEXTO: A angiogênese terapêutica é uma modalidade de tratamento para pacientes com insuficiência arterial crônica que não têm indicação para revascularização direta ou angioplastia e que não tiveram uma resposta satisfatória ao tratamento clínico. Entre as drogas utilizadas para essa finalidade está a prostaglandina E1 (PGE1. OBJETIVO: Estudar os aspectos morfológicos na gênese de capilares sanguíneos em músculo esquelético do membro caudal de ratos submetidos à isquemia sob a ação da PGE1, administrada por via intramuscular (IM ou endovenosa (EV. MÉTODOS: Foram utilizados 48 ratos, linhagem Wistar-UEM, distribuídos aleatoriamente em três grupos de 16, redistribuídos igualmente em dois subgrupos, observados no 7º e 14º dias, sendo um grupo controle onde apenas foi provocada a isquemia no membro, outro com a isquemia e a injeção da PGE1 via IM e outro com a isquemia e a injeção da PGE1 EV. Para análise dos resultados, foram realizadas a coloração com hematoxilina e eosina (HE e coloração imuno-histoquímica. RESULTADOS: Constatou-se um aumento estatisticamente significativo no número de capilares nos subgrupos com o uso da PGE1 IM e EV, através da contagem nos cortes corados com HE. A imunomarcação não foi eficiente para a quantificação dos capilares. CONCLUSÕES: A PGE1, administrada por via IM ou EV, promoveu, após 14 dias de observação, um aumento no número de capilares no músculo esquelético de ratos submetido à isquemia, identificáveis histologicamente com a coloração em HE. A imunocoloração não permitiu estabelecer uma correlação com o aumento de vasos encontrados na coloração com HE.BACKGROUND: Therapeutic angiogenesis is a treatment modality for patients with chronic arterial insufficiency who do not have indication for direct reconstruction or angioplasty and who were not successfully submitted to clinical treatment. Prostaglandin E1 (PGE1 is one of the drugs used for this

Rac1- a novel regulator of contraction-stimulated glucose uptake in skeletal muscle
DEFF Research Database (Denmark)

-stimulated glucose uptake in skeletal muscle, since muscle-specific Rac1 knockout mice display reduced ex vivo contraction- and in vivo exercise-stimulated glucose uptake in skeletal muscle. The molecular mechanisms by which Rac1 regulate glucose uptake is presently unknown. However, recent studies link Rac1......Muscle contraction stimulates muscle glucose uptake by facilitating translocation of the glucose transporter 4 from intracellular locations to the cell surface, which allows for diffusion of glucose into the myofibers. However, the intracellular mechanisms regulating this process are not well...... understood. The GTPase, Rac1 has, until recently, only been investigated with regards to its involvement in insulin-stimulated glucose uptake. However, we recently found that Rac1 is activated during muscle contraction and exercise in mice and humans. Remarkably, Rac1 seems to be necessary for exercise/contraction...
