Highlights: •We succeeded to control the proteasome localization by the anchor-away technique. •Nuclear proteasome-depleted cells showed a lethal phenotype. •Cytoplasmic proteasomes are not indispensable for cell growth in dividing cells. -- Abstract: The 26S proteasome is an essential protease complex responsible for the degradation of ubiquitinated proteins in eukaryotic cells. In rapidly proliferating yeast cells, proteasomes are mainly localized in the nucleus, but the biological significance of the proteasome localization is still unclear. In this study, we investigated the relationship between the proteasome localization and the functions by the anchor-away technique, a ligand-dependent sequestration of a target protein into specificmore » compartment(s). Anchoring of the proteasome to the plasma membrane or the ribosome resulted in conditional depletion of the nuclear proteasomes, whereas anchoring to histone resulted in the proteasome sequestration into the nucleus. We observed that the accumulation of ubiquitinated proteins in all the proteasome-targeted cells, suggesting that both the nuclear and cytoplasmic proteasomes have proteolytic functions and that the ubiquitinated proteins are produced and degraded in each compartment. Consistent with previous studies, the nuclear proteasome-depleted cells exhibited a lethal phenotype. In contrast, the nuclear sequestration of the proteasome resulted only in a mild growth defect, suggesting that the cytoplasmic proteasomes are not basically indispensable for cell growth in rapidly growing yeast cells.« less

Phosphorus of plant-based feedstuffs for monogastric animals is mainly in the form of phytic P, which has a very low bioavailability. The nondigested phytic P may contribute to P pollution. Furthermore, phytic acid may reduce digestibility of other minerals and protein. This study evaluated effects of the microbial 6-phytase RONOZYME HiPhos on apparent ileal digestibility of P, phytic acid, Ca, CP, energy, and AA in six 60-d-old ileorectal anastomosed pigs. In a duplicated 3 × 3 Latin square design, pigs had free access to alternatively a corn (Zea mays)-soybean (Glycine max) meal-barley (Hordeum vulgare)-based diet or this diet supplemented with RONOZYME HiPhos at either 500 units/kg (RH500) or 1000 units/kg (RH1000). Pigs fed diets supplemented with RH500 or RH1000 increased (P < 0.05) digestibility of P, Ca, and Lys. Pigs fed diet RH1000 increased (P < 0.05) digestibility of CP, total AA, indispensable AA, Glu + Gln, His, Gly, Ala, Tyr, Leu, Phe, and Met. Similar to growth trials with increased total tract digestibility of P and Ca, phytase increased apparent ileal digestibility of these indispensable minerals and phytate. The phytase increased digestibility of CP and indispensable AA indicating a better availability of plant-based proteins.

2000-12-01

A good olfactory sense is indispensable for any professional chef because it is not only an essential means of establishing the quality and state of conservation of the ingredients they buy, but is also one of the most effective ways of following the progress of their cooking. Chefs are therefore also faced with the challenge of refining this capacity in such a way as to ensure that aromas and flavours are combined in a pleasing and appealing manner. By following the typical everyday activities of a professional chef, it is possible to discover how important a "trained" olfactory sense is in ensuring that a customer entering a restaurant is duly satisfied. The aim of this paper is to offer some insights into the language, practice and use of olfaction in the culinary field.

A norm knockout method on indirect reciprocity to reveal indispensable norms

2017-01-01

Although various norms for reciprocity-based cooperation have been suggested that are evolutionarily stable against invasion from free riders, the process of alternation of norms and the role of diversified norms remain unclear in the evolution of cooperation. We clarify the co-evolutionary dynamics of norms and cooperation in indirect reciprocity and also identify the indispensable norms for the evolution of cooperation. Inspired by the gene knockout method, a genetic engineering technique, we developed the norm knockout method and clarified the norms necessary for the establishment of cooperation. The results of numerical investigations revealed that the majority of norms gradually transitioned to tolerant norms after defectors are eliminated by strict norms. Furthermore, no cooperation emerges when specific norms that are intolerant to defectors are knocked out. PMID:28276485

La estimación de los desplazamientos al rojo (redshift) de las galaxias, derivados mediante fotometría multi-banda, se conoce con el nombre de photometric redshifts (photo-z). Es bien sabido que la precisión alcanzable por estas técnicas puede verse incrementada si se dispone de una muestra espectroscópica de galaxias (cuyos redshifts (spec-z) sean conocidos) con la que re-calibrar los puntos cero fotométricos. (Coe et al. 2006, Ilbert et al. 2008, Molino et al. 2012 in prep). ALHAMBRA-survey, que es un cartografiado extragaláctico (de ˜4 grados cuadrados) dedicado a la realización de un estudio de la evolución de las propiedades y contenido del Universo (Moles et al. 2005, 2008), presenta solapamientos parciales con otros cartografiados espectroscópicos ya existentes con el objetivo de validar y mejorar la precisión de sus photo-z. Sin embargo, dada la variabilidad fotométrica entre sus campos, resulta ineficiente extrapolar las correcciones de punto cero, introduciendo sesgos de inhomogeneidad en la precisión de los resultados. En este trabajo se presenta una nueva metodología que permite mejorar la calibración de los puntos cero fotométricos mediante la utilización de la información estadística proporcionada por los propios photo-z. Mediante esta técnica resulta posible no sólo mejorar la precisión de las estimaciones sino, además, soslayar la necesidad de obtener grandes muestras espectroscópicas.

Introducción. La leishmaniasis cutánea es una enfermedad causada por parásitos del género Leishmania que tiene gran incidencia en Colombia. El diagnóstico y la identificación de la especie infecciosa son factores críticos en el momento de escoger e iniciar el tratamiento. Actualmente, los métodos de diagnóstico y tipificación requieren procedimientos complejos, por lo que es necesario validar nuevos marcadores moleculares y métodos que simplifiquen el proceso.Objetivo. Desarrollar una herramienta basada en la reacción en cadena de la polimerasa (PCR) con curvas de fusión (High Resolution Melting; PCR-HRM) para el diagnóstico y tipificación de las tres especies de Leishmania de importancia epidemiológica en casos de leishmaniasis cutánea en Colombia.Materiales y métodos. Los genomas de Leishmania panamensis, L. braziliensis y L. guyanensis se compararon mediante métodos bioinformáticos. Las regiones específicas de especie identificadas se validaron mediante PCR. Para los marcadores seleccionados se diseñó una PCR-HRM y se estimaron algunos parámetros de validez y seguridad usando aislamientos de pacientes colombianos caracterizados previamente mediante PCR y análisis de polimorfismos en la longitud de los fragmentos de restricción (Restriction Fragment Length Polymorphism - RFLP; PCR-RFLP) del gen hsp70.Resultados. El análisis genómico comparativo mostró 24 regiones específicas de especie. Sin embargo, la validación mediante PCR solo identificó un marcador específico para cada especie de Leishmania. Los otros marcadores mostraron amplificación cruzada. El límite de detección para los tres marcadores seleccionados fue de un parásito, mientras que la sensibilidad, la especificidad, el valor predictivo positivo y el negativo fueron de 91,4, 100, 100 y 75 %, respectivamente.Conclusiones. Las tres regiones seleccionadas pueden emplearse como marcadores moleculares en el diagnóstico y tipificación de las especies causantes de la leishmaniasis cutánea en Colombia.

Quantifying Users' Interconnectedness in Online Social Networks - An Indispensible Step for Economic Valuation

NASA Astrophysics Data System (ADS)

Gneiser, Martin; Heidemann, Julia; Klier, Mathias; Landherr, Andrea; Probst, Florian

Online social networks have been gaining increasing economic importance in light of the rising number of their users. Numerous recent acquisitions priced at enormous amounts have illustrated this development and revealed the need for adequate business valuation models. The value of an online social network is largely determined by the value of its users, the relationships between these users, and the resulting network effects. Therefore, the interconnectedness of a user within the network has to be considered explicitly to get a reasonable estimate for the economic value. Established standard business valuation models, however, do not sufficiently take these aspects into account. Thus, we propose a measure based on the PageRank-algorithm to quantify users’ interconnectedness in an online social network. This is a first but indispensible step towards an adequate economic valuation of online social networks.

Succesful Lean Manufacturing Implementation: Internal Key Influencing Factors

NASA Astrophysics Data System (ADS)

Virginia, Iuga; Claudiu, Kifor

2015-09-01

Manufacturing sectors and companies all over the world are successfully implementing lean principles within their processes. Nowadays, lean has become an indispensable part of global players. Companies worldwide need to be aware of multiple factors which weigh heavily on the success or failure of lean implementation. This paper focuses on giving a brief and structured overview over the fundamental organizational factors which play a substantial role for the lean manufacturing (LM) implementation process. The study below focuses on internal factors which are indispensable for a successful LM implementation within organizations. It is imperative that these internal factors are known, recognized and taken into consideration during the whole LM implementation process. Ignoring their influence on the process's implementation may lead to endangering the expected results or to making the process more difficult which could result in much higher human resource consumption.

Identification of critical regulatory genes in cancer signaling network using controllability analysis

NASA Astrophysics Data System (ADS)

Ravindran, Vandana; Sunitha, V.; Bagler, Ganesh

2017-05-01

Cancer is characterized by a complex web of regulatory mechanisms which makes it difficult to identify features that are central to its control. Molecular integrative models of cancer, generated with the help of data from experimental assays, facilitate use of control theory to probe for ways of controlling the state of such a complex dynamic network. We modeled the human cancer signaling network as a directed graph and analyzed it for its controllability, identification of driver nodes and their characterization. We identified the driver nodes using the maximum matching algorithm and classified them as backbone, peripheral and ordinary based on their role in regulatory interactions and control of the network. We found that the backbone driver nodes were key to driving the regulatory network into cancer phenotype (via mutations) as well as for steering into healthy phenotype (as drug targets). This implies that while backbone genes could lead to cancer by virtue of mutations, they are also therapeutic targets of cancer. Further, based on their impact on the size of the set of driver nodes, genes were characterized as indispensable, dispensable and neutral. Indispensable nodes within backbone of the network emerged as central to regulatory mechanisms of control of cancer. In addition to probing the cancer signaling network from the perspective of control, our findings suggest that indispensable backbone driver nodes could be potentially leveraged as therapeutic targets. This study also illustrates the application of structural controllability for studying the mechanisms underlying the regulation of complex diseases.

Objetivo: El objetivo principal del presente estudio consistió en determinar la prevalencia de los cambios en la interfase vitreomacular (IVM) mediante tomografía de coherencia óptica (OCT) en la población general. En segundo lugar, se describieron otros cambios de la OCT. Métodos: Las anomalías en la IVM se diagnosticaron mediante OCT y se distribuyeron de acuerdo con la clasificación del grupo International Vitreomacular Traction Study (estudio internacional de tracción vitreomacular, IVTS, por sus siglas en inglés) y se dividieron en 3 grados según John et al. [Retina 2014;34:442-446]. Resultados: La prevalencia calculada de anomalías vitreomaculares en la población belga de ≥50 años fue del 1,17% [intervalo de confianza (IC 0,38-3,62)] en el caso de tracción vitreomacular (TVM) focal de grado 1; del 0,39% (IC 0,05-2,76) en el caso de TVM focal de grado 2; del 8,17% (IC 5,33-12,53) en el caso de adhesión vitreomacular focal; y del 17,9% (IC 13,41-23,9) en el caso de adhesión vitreomacular difusa. Conclusiones: Se presentó la prevalencia de anomalías vitreomaculares en un estudio de cohortes belga. Estos resultados concuerdan en gran medida con los datos presentados previamente sobre la prevalencia de la TVM. Un conocimiento correcto sobre la epidemiología de las alteraciones en la IVM y un diagnóstico temprano permitirán una intervención satisfactoria. © 2017 S. Karger AG, Basel.

The aim of this study was to establish the validity and reliability of an instrument (Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería) used to assess the dependency level in acutely hospitalised patients. This instrument is novel, and it is based on the Nursing Outcomes Classification. Multiple existing instruments for needs assessment have been poorly validated and based predominately on interventions. Standardised Nursing Languages offer an ideal framework to develop nursing sensitive instruments. A cross-sectional validation study in two acute care hospitals in Spain. This study was implemented in two phases. First, the research team developed the instrument to be validated. In the second phase, the validation process was performed by experts, and the data analysis was conducted to establish the psychometric properties of the instrument. Seven hundred and sixty-one patient ratings performed by nurses were collected during the course of the research study. Data analysis yielded a Cronbach's alpha of 0·91. An exploratory factorial analysis identified three factors (Physiological, Instrumental and Cognitive-behavioural), which explained 74% of the variance. Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería was demonstrated to be a valid and reliable instrument based on its use in acutely hospitalised patients to assess the level of dependency. Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería can be used as an assessment tool in hospitalised patients during the nursing process throughout the entire hospitalisation period. It contributes information to support decisions on nursing diagnoses, interventions and outcomes. It also enables data codification in large databases. © 2014 John Wiley & Sons Ltd.

Irimia, Daniel; Ellett, Felix

2016-01-01

Inflammation is an indispensable component of the immune response, and leukocytes provide the first line of defense against infection. Although the major stereotypic leukocyte behaviors in response to infection are well known, the complexities and idiosyncrasies of these phenotypes in conditions of disease are still emerging. Novel tools are indispensable for gaining insights into leukocyte behavior, and in the past decade, microfluidic technologies have emerged as an exciting development in the field. Microfluidic devices are readily customizable, provide tight control of experimental conditions, enable high precision of ex vivo measurements of individual as well as integrated leukocyte functions, and have facilitated the discovery of novel leukocyte phenotypes. Here, we review some of the most interesting insights resulting from the application of microfluidic approaches to the study of the inflammatory response. The aim is to encourage leukocyte biologists to integrate these new tools into increasingly more sophisticated experimental designs for probing complex leukocyte functions. PMID:27194799

Since September 2009 the handling of living wills has been regulated by law. Even though a medical consultation is not imperative for the drawing up of a living will, first surveys have shown that medical information about clinical pictures and treatment options lead to an important specification of living wills. For the first time in Germany, a questionnaire has been developed to investigate the impact of medical consultations on the content of living wills. It revealed that nearly all the people surveyed who had already drawn up a living will wished to change the content of their completed will after attending the seminar because the previous version was no longer in accordance with their wishes. In the light of the frequent difficulties in hospitals concerning how to apply a living will to an actual clinical situation, we believe structured medical consultations to be indispensable. © Georg Thieme Verlag KG Stuttgart · New York.

Applicability, Indispensability, and Underdetermination: Puzzling Over Wigner's `Unreasonable Effectiveness of Mathematics'

NASA Astrophysics Data System (ADS)

Gelfert, Axel

2014-05-01

In his influential 1960 paper `The Unreasonable Effectiveness of Mathematics in the Natural Sciences', Eugene P. Wigner raises the question of why something that was developed without concern for empirical facts—mathematics—should turn out to be so powerful in explaining facts about the natural world. Recent philosophy of science has developed `Wigner's puzzle' in two different directions: First, in relation to the supposed indispensability of mathematical facts to particular scientific explanations and, secondly, in connection with the idea that aesthetic criteria track theoretical desiderata such as empirical success. An important aspect of Wigner's article has, however, been overlooked in these debates: his worries about the underdetermination of physical theories by mathematical frameworks. The present paper argues that, by restoring this aspect of Wigner's argument to its proper place, Wigner's puzzle may become an instructive case study for the teaching of core issues in the philosophy of science and its history.

Our results may be briefly summarized: 1. Blood, when defibrinated, soon loses its power to maintain the activity of the higher nervous centers, and its nutritive properties for all tissues quickly diminish. 2. Artificial fluids, as a substitute for blood, are not satisfactory. 3. The proper oxygenation of the blood is an indispensable adjunct in the resuscitation of an animal. 4. The heart usually continues to beat for some minutes after it ceases to affect a mercury manometer, and resuscitation of it within this period by extra-thoracic massage and artificial respiration is sometimes successful. 5. Resuscitation of the heart by direct massage is the most certain method at our command. 6. A proper blood-pressure is an indispensable condition for the continued normal activity of the heart. 7. Anæsthetics, hemorrhage and induced currents applied to the heart render resuscitation more difficult than asphyxia alone. PMID:19867138

Craniofacial sutures govern the shape of the craniofacial skeleton during postnatal development. The differentiation of suture mesenchymal cells to osteoblasts is precisely regulated in part by signaling through cell surface receptors that interact with extracellular proteins. Here we report that fibulin-5, a key extracellular matrix protein, is important for craniofacial skeletal development in mice. Fibulin-5 is deposited as a fibrous matrix in cranial neural crest-derived mesenchymal tissues, including craniofacial sutures. Fibulin-5-null mice show decreased premaxillary bone outgrowth during postnatal stages. While premaxillo-maxillary suture mesenchymal cells in fibulin-5-null mice were capable of differentiating into osteoblasts, suture cells in mutant mice weremore » less proliferative. Our study provides the first evidence that fibulin-5 is indispensable for the regulation of facial suture mesenchymal cell proliferation required for craniofacial skeletal morphogenesis. - Highlights: • Fibulin-5 is deposited in cranial neural crest-derived mesenchymal tissues. • Fibulin-5-null mice show decreased premaxillary bone growth during postnatal stage. • Fibulin-5 is indispensable for facial suture mesenchymal cell proliferation.« less

Aquaporins in the kidney: emerging new aspects.

PubMed

Yamamoto, T; Sasaki, S

1998-10-01

Since 1992 and the discovery of an MIP (major intrinsic protein of lens fiber cell) homologue protein that selectively permeates water, aquaporin (AQP), there has been an explosion of research in this field. Early research speculated that aquaporins played indispensible physiological roles in bacteria and plants, as well as in mammalian organs such as red blood cells, kidney, eye, brain and lung, where water transport rapidly takes place. Yet human subjects were identified who lacked AQP1 and yet had no apparent phenotypical changes clinically. To date 10 aquaporins have been discovered and a plethora of MIP members, and their prevalance in almost all organisms is a testament to their indispensible roles in the body, possibly as water and small neutral solute transporting channels. The recent localization of many different aquaporins in the same organ indicates that they may work cooperatively, which may partially explain the mystery of their physiological mechanism. Because the physiological roles of most aquaporins are currently only speculation, more extensive research is necessary to understand the exact function of each aquaporin.

Measuring the electron affinity of organic solids: an indispensable new tool for organic electronics.

PubMed

Yoshida, Hiroyuki

2014-04-01

Electron affinity is a fundamental energy parameter of materials. In organic semiconductors, the electron affinity is closely related to electron conduction. It is not only important to understand fundamental electronic processes in organic solids, but it is also indispensable for research and development of organic semiconductor devices such as organic light-emitting diodes and organic photovoltaic cells. However, there has been no experimental technique for examining the electron affinity of organic materials that meets the requirements of such research. Recently, a new method, called low-energy inverse-photoemission spectroscopy, has been developed. A beam of low-energy electrons is focused onto the sample surface, and photons emitted owing to the radiative transition to unoccupied states are then detected. From the onset of the spectral intensity, the electron affinity is determined within an uncertainty of 0.1 eV. Unlike in conventional inverse-photoemission spectroscopy, sample damage is negligible and the resolution is improved by a factor of 2. The principle of the method and several applications are reported.

Is Ammonium Peroxydisulate Indispensable for Preparation of Aniline-Derived Iron-Nitrogen-Carbon Electrocatalysts?

PubMed

Xie, Nan-Hong; Yan, Xiang-Hui; Xu, Bo-Qing

2016-09-08

Iron and nitrogen co-doped carbon (Fe-N-C) materials are among the most active non-precious metal catalysts that could replace Pt-based electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells and metal-air batteries. The synthesis of the Fe-N-C catalysts often involves the use of aniline as the precursor for both N and C and ammonium peroxydisulfate (APS) as an indispensable oxidative initiator for aniline polymerization. Herein, a detailed structure and catalytic ORR performance comparison of aniline-derived Fe-N-C catalysts synthesized with and without the use of APS is reported. The APS-free preparation, which uses Fe(III) ions as the Fe source as well as the aniline polymerization initiator, results in a simple Fe-N-C catalyst with a high activity for the ORR. We show that APS is not necessary for the preparation and even detrimental to the performance of the catalyst. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Robustness of the Rotary Catalysis Mechanism of F1-ATPase*

PubMed Central

Watanabe, Rikiya; Matsukage, Yuki; Yukawa, Ayako; Tabata, Kazuhito V.; Noji, Hiroyuki

2014-01-01

F1-ATPase (F1) is the rotary motor protein fueled by ATP hydrolysis. Previous studies have suggested that three charged residues are indispensable for catalysis of F1 as follows: the P-loop lysine in the phosphate-binding loop, GXXXXGK(T/S); a glutamic acid that activates water molecules for nucleophilic attack on the γ-phosphate of ATP (general base); and an arginine directly contacting the γ-phosphate (arginine finger). These residues are well conserved among P-loop NTPases. In this study, we investigated the role of these charged residues in catalysis and torque generation by analyzing alanine-substituted mutants in the single-molecule rotation assay. Surprisingly, all mutants continuously drove rotary motion, even though the rotational velocity was at least 100,000 times slower than that of wild type. Thus, although these charged residues contribute to highly efficient catalysis, they are not indispensable to chemo-mechanical energy coupling, and the rotary catalysis mechanism of F1 is far more robust than previously thought.

Introducción: existen alteraciones frecuentes en la alimentación de la población infantil femenina, y especialmente en atletas de deportes estéticos por la presión ejercida para mantener un cuerpo.Objetivos: evaluar los aspectos nutricionales, antropométricos y la percepción del peso de niñas que realizan gimnasia rítmica frente a un grupo control.Métodos: estudio descriptivo comparativo. Se compararon 25 niñas gimnastas con 25 niñas no gimnastas (control). Se realizó una valoración antropométrica, mediante protocolo ISAK, y nutricional, mediante un registro dietético de siete días; así como una valoración cuantitativa y cualitativa de la ingesta alimentaria, mediante el software DIAL. Se rellenó un cuestionario de hábitos y sobre la percepción de su peso corporal.Resultados: los datos antropométricos no presentaron diferencias significativas entre ambos grupos, excepto en los pliegues cutáneos y el porcentaje de grasa, el cual era estadísticamente inferior en gimnastas. La ingesta energética (1.413 ± 283 Kcal/día) de las gimnastas era inferior a la recomendada por la Food and Nutrition Board de acuerdo a su edad. La distribución de los macronutrientes cumplía con los valores normales establecidos (10-30% proteínas, 45-65% hidratos, 20-35% grasas). El 32% de las gimnastas y el 36,4% de las niñas control consideraron que les gustaría pesar menos.Conclusión: teniendo en cuenta la intensa actividad de las gimnastas, sus requerimientos energéticos deberían ajustarse a ello, ya que esto contribuirá a su desarrollo y crecimiento y a una mejor ejecución del ejercicio. En la muestra estudiada, el consumo de alimentos de las gimnastas se aleja de una alimentación equilibrada. No se observaron comportamientos diferentes en la percepción del peso entre ambos grupos.

2016-08-01

A wide variety of animal protein-based ingredients is commonly used in the pet food products. The raw ingredients and processing procedures used may greatly affect protein quality. Testing the quality of alternative protein sources is necessary and contributes to the sustainability of pet foods. The objective of this study was to test the chemical composition of 8 protein sources intended for use in dog and cat foods (calamari meal, pork peptone, alligator meal, lamb meal, venison meal, chicken meal, and 2 duck meals), and evaluate their true nutrient digestibility and nitrogen-corrected true ME (TMEn) using the precision-fed cecectomized rooster assay. Calamari meal and pork peptone had lower ash (4.4 and 3.6% of DM, respectively) but greater CP (88.1 and 80.5% of DM, respectively) and either greater or similar GE (5.6 and 5.3 kcal/g of DM, respectively) compared with alligator, lamb, venison, chicken, and duck meals (11.8 to 24.5% ash, 58.7 to 65.9% CP, and 4.6 to 5.3 kcal GE/g). Acid-hydrolyzed fat (AHF) was lower in calamari meal (8.7% of DM) compared with the other proteins tested (15.5-22.1% of DM). True nutrient digestibility was variable among the protein sources (52 to 79% of DM, 60 to 83% of OM, 78 to 92% of AHF, and 70 to 89% of GE) with pork peptone having the highest DM, AHF, and GE digestibility and calamari meal having the highest OM digestibility. True indispensable AA digestibility was highest for calamari meal, with all AA having a digestibility greater than 90%. Except for histidine, all indispensable AA had a digestibility over 85% for pork peptone. In contrast, true indispensable AA digestibility was lowest for lamb meal, with histidine having digestibility less than 70% and the other entire indispensable AA having digestibility between 72 and 88%. The TMEn of calamari meal (4.82 kcal/g DM and 86.9% of GE) was greater ( < 0.05) than the other protein sources. The lamb meal had the lowest TMEn value (3.12 kcal/g DM and 66.9% of GE), with others being intermediate (3.46-4.09 kcal/g DM and 71.2-77.9% of GE). This study demonstrates the considerable variability that exists not only in the chemical composition but also in the true nutrient digestibility among protein sources intended for use in dog and cat foods and justifies further in vivo testing of novel protein sources.

Niobium and tantalum: indispensable twins

USGS Publications Warehouse

Schulz, Klaus; Papp, John

2014-01-01

Niobium and tantalum are transition metals almost always paired together in nature. These “twins” are difficult to separate because of their shared physical and chemical properties. In 1801, English chemist Charles Hatchett uncovered an unknown element in a mineral sample of columbite; John Winthrop found the sample in a Massachusetts mine and sent it to the British Museum in London in 1734. The name columbium, which Hatchet named the new element, came from the poetic name for North America—Columbia—and was used interchangeably for niobium until 1949, when the name niobium became official. Swedish scientist Anders Ekberg discovered tantalum in 1802, but it was confused with niobium, because of their twinned properties, until 1864, when it was recognized as a separate element. Niobium is a lustrous, gray, ductile metal with a high melting point, relatively low density, and superconductor properties. Tantalum is a dark blue-gray, dense, ductile, very hard, and easily fabricated metal. It is highly conductive to heat and electricity and renowned for its resistance to acidic corrosion. These special properties determine their primary uses and make niobium and tantalum indispensable.

Insights into the Structure of Dimeric RNA Helicase CsdA and Indispensable Role of Its C-Terminal Regions

DOE PAGES

Xu, Ling; Wang, Lijun; Peng, Junhui; ...

2017-12-05

CsdA has been proposed to be essential for the biogenesis of ribosome and gene regulation after cold shock. However, the structure of CsdA and the function of its long C-terminal regions are still unclear. For this study, we solved all of the domain structures of CsdA and found two previously uncharacterized auxiliary domains: a dimerization domain (DD) and an RNA-binding domain (RBD). Small-angle X-ray scattering experiments helped to track the conformational flexibilities of the helicase core domains and C-terminal regions. Biochemical assays revealed that DD is indispensable for stabilizing the CsdA dimeric structure. We also demonstrate for the first timemore » that CsdA functions as a stable dimer at low temperature. The C-terminal regions are critical for RNA binding and efficient enzymatic activities. CsdA_RBD could specifically bind to the regions with a preference for single-stranded G-rich RNA, which may help to bring the helicase core to unwind the adjacent duplex.« less

Axl is not an indispensable factor for Zika virus infection in mice.

Wang, Zhao-Yang; Wang, Zai; Zhen, Zi-Da; Feng, Kai-Hao; Guo, Jing; Gao, Na; Fan, Dong-Ying; Han, Dai-Shu; Wang, Pei-Gang; An, Jing

2017-08-01

Recently, Zika virus (ZIKV) outbreak has been associated with a sharp increase in cases of Guillain-Barré syndrome and severe fetal abnormalities. However, the mechanism underlying the interaction of ZIKV with host cells is not yet clear. Axl, a receptor tyrosine kinase, is postulated as a receptor for ZIKV entry; however, its in vivo role during ZIKV infection and its impact on the outcome of the disease have not been fully characterized and evaluated. Moreover, there are contradictory results on its involvement in ZIKV infection. Here we utilized Axl-deficient mice (Axl-/-) and their littermates (Axl+/-) to study the in vivo role of Axl in ZIKV infection. Our results showed that both Axl+/- and Axl-/- suckling mice supported the replication of ZIKV and presented clinical manifestations. No significant difference has been found between Axl-deficient mice and their littermates in terms of the survival rate, clinical manifestations, viral load, ZIKV distribution and histopathological changes in major organs. These results therefore indicate that Axl is not an indispensable factor for ZIKV infection in mice.

Colour thresholding and objective quantification in bioimaging

NASA Technical Reports Server (NTRS)

Fermin, C. D.; Gerber, M. A.; Torre-Bueno, J. R.

1992-01-01

Computer imaging is rapidly becoming an indispensable tool for the quantification of variables in research and medicine. Whilst its use in medicine has largely been limited to qualitative observations, imaging in applied basic sciences, medical research and biotechnology demands objective quantification of the variables in question. In black and white densitometry (0-256 levels of intensity) the separation of subtle differences between closely related hues from stains is sometimes very difficult. True-colour and real-time video microscopy analysis offer choices not previously available with monochrome systems. In this paper we demonstrate the usefulness of colour thresholding, which has so far proven indispensable for proper objective quantification of the products of histochemical reactions and/or subtle differences in tissue and cells. In addition, we provide interested, but untrained readers with basic information that may assist decisions regarding the most suitable set-up for a project under consideration. Data from projects in progress at Tulane are shown to illustrate the advantage of colour thresholding over monochrome densitometry and for objective quantification of subtle colour differences between experimental and control samples.

Introducción. La sífilis es una enfermedad producida por Treponema pallidum subespecie pallidum cuya incidencia mundial es de 12 millones de casos por año, aproximadamente; de estos, más de dos millones se presentan en mujeres gestantes, siendo la sífilis congénita la complicación más grave de esta infección en el embarazo.Objetivo. Detectar la presencia de T. pallidum subespecie pallidum en muestras clínicas para el diagnóstico de sífilis congénita mediante reacción en cadena de la polimerasa (PCR) anidada y determinar su concordancia con las pruebas serológicas.Materiales y métodos. Mediante PCR convencional y anidada, se amplificaron tres genes diana (polA, 16S ADNr y TpN47) y se confirmaron los productos de amplificación de los genes TpN47 y polA por secuenciación. Las pruebas serológicas empleadas fueron la VDRL (Venereal Disease Research Laboratory), la de reagina plasmática rápida (Rapid Plasma Reagin, RPR) y la de aglutinación de partículas para Treponema pallidum (Treponema pallidum Particle Agglutination Assay, TPPA).Resultados. La sensibilidad para la PCR convencional fue de 52 pg y, para la PCR anidada, de 0,52 pg. La especificidad con los iniciadores TpN47 y polA fue de 100 %; los resultados de la secuenciación mostraron una identidad de 97 % con T. pallidum. En 70 % de las muestras, los resultados de las pruebas serológicas y la PCR anidada concordaron.Conclusión. El gen TpN47 resultó ser el mejor blanco molecular para la identificación de T. pallidum. La PCR anidada se presenta como una alternativa de diagnóstico molecular promisoria para el diagnóstico de sífilis congénita.

Biogenesis of cytosolic ribosomes requires the essential iron–sulphur protein Rli1p and mitochondria

2005-01-01

Mitochondria perform a central function in the biogenesis of cellular iron–sulphur (Fe/S) proteins. It is unknown to date why this biosynthetic pathway is indispensable for life, the more so as no essential mitochondrial Fe/S proteins are known. Here, we show that the soluble ATP-binding cassette (ABC) protein Rli1p carries N-terminal Fe/S clusters that require the mitochondrial and cytosolic Fe/S protein biogenesis machineries for assembly. Mutations in critical cysteine residues of Rli1p abolish association with Fe/S clusters and lead to loss of cell viability. Hence, the essential character of Fe/S clusters in Rli1p explains the indispensable character of mitochondria in eukaryotes. We further report that Rli1p is associated with ribosomes and with Hcr1p, a protein involved in rRNA processing and translation initiation. Depletion of Rli1p causes a nuclear export defect of the small and large ribosomal subunits and subsequently a translational arrest. Thus, ribosome biogenesis and function are intimately linked to the crucial role of mitochondria in the maturation of the essential Fe/S protein Rli1p. PMID:15660134

Japan Fulbright Memorial Fund Program Opens New Avenues for Effective Technology Integration into Education

NASA Astrophysics Data System (ADS)

Paoletti, Franco; Carlucci, Lisa Marie

2006-04-01

Technology is increasingly playing a major role in today's education often integrated into instruction to become one of the teacher's most effective and often indispensable tools used in the classroom. It can be said that the use of technology at the beginning of this new millennium is affecting the instructional process and it is changing some of its basic connotations. The presented work analyzes the impact of various technologies on education emphasizing the advantages provided by a successful integration, the obstacles encountered along the way, and the methodologies currently used in the process. ``Educational exchange can turn nations into people, contributing as no other form of communication can to the humanizing of international relations'' (Senator J.M. Fulbright). Technology of this modern era is providing the indispensable tool to achieve this superior level of communication overcoming historical, cultural, and language barriers. In the context of the Japan Fulbright Memorial Fund (JFMF) Teacher Program, we analyze the impact of technology on educational cross-cultural exchanges to raise awareness and interest of the scientific/educational community on the need of establishing stronger international relations promoting world peace and global prosperity.

Nutritive and Bioactive Proteins in Breastmilk.

PubMed

Haschke, Ferdinand; Haiden, Nadja; Thakkar, Sagar K

2016-01-01

Protein ingested with breast milk provides indispensable amino acids which are necessary for new protein synthesis for growth and replacement of losses via urine, feces, and the skin. Protein gain in the body of an infant is highest during the first months when protein concentrations in breast milk are higher than during later stages of lactation. Low-birth-weight infants have higher protein needs than term infants and need protein supplements during feeding with breastmilk. Based on our better understanding of protein evolution in breastmilk during the stages of lactation, new infant formulas with lower protein concentration but better protein quality have been created, successfully tested, and are now available in many countries. Besides providing indispensable amino acids, bioactive protein in breast milk can be broadly classified into 4 major functions, that is, providing protection from microbial insults and immune protection, aiding in digestive functions, gut development, and being carriers for other nutrients. Individual proteins and their proposed bioactivities are summarized in this paper in brief. Indeed, some proteins like lactoferrin and sIgA have been extensively studied for their biological functions, whereas others may require more data in support to further validate their proposed functions. © 2017 S.

Validation of maternal cardiac output assessed by transthoracic echocardiography against pulmonary artery catheterization in severely ill pregnant women: prospective comparative study and systematic review.

Most severe pregnancy complications are characterized by profound hemodynamic disturbances, thus there is a need for validated hemodynamic monitoring systems for pregnant women. Pulmonary artery catheterization (PAC) using thermodilution is the clinical gold standard for the measurement of cardiac output (CO), however this reference method is rarely performed owing to its invasive nature. Transthoracic echocardiography (TTE) allows non-invasive determination of CO. We aimed to validate TTE against PAC for the determination of CO in severely ill pregnant women. This study consisted of a meta-analysis combining data from a prospective study and a systematic review. The prospective arm was conducted in Pretoria, South Africa, in 2003. Women with severe pregnancy complications requiring invasive monitoring with PAC according to contemporary guidelines were included. TTE was performed within 15 min of PAC and the investigator was blinded to the PAC measurements. Comparative measurements were extracted from similar studies retrieved from a systematic review of the literature and added to a database. Simultaneous CO measurements by TTE and PAC were compared. Agreement between methods was assessed using Bland-Altman statistics and intraclass correlation coefficients (ICC). Thirty-four comparative measurements were included in the meta-analysis. Mean CO values obtained by PAC and TTE were 7.39 L/min and 7.18 L/min, respectively. The bias was 0.21 L/min with lower and upper limits of agreement of -1.18 L/min and 1.60 L/min, percentage error was 19.1%, and ICC between the two methods was 0.94. CO measurements by TTE show excellent agreement with those obtained by PAC in pregnant women. Given its non-invasive nature and availability, TTE could be considered as a reference for the validation of other CO techniques in pregnant women. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd. Las complicaciones del embarazo más graves se caracterizan por trastornos hemodinámicos serios, debido a los cuales existe la necesidad de sistemas validados de monitorización hemodinámica para mujeres embarazadas. Aunque la cateterización de la arteria pulmonar (CAP) mediante termodilución es el patrón de referencia clínico para la medición del gasto cardíaco (GC), este método se usa con poca frecuencia debido a su naturaleza invasiva. La ecocardiografía transtorácica (ETT) permite la determinación no invasiva del GC. El objetivo de este estudio fue validar la ETT frente al CAP para determinar el GC en mujeres embarazadas gravemente enfermas. MÉTODOS: Este estudio consistió en un metaanálisis que combinó datos de un estudio prospectivo y una revisión sistemática. El estudio prospectivo se llevó a cabo en Pretoria (Sudáfrica) en 2003. Se incluyeron mujeres con complicaciones graves en el embarazo que requerían una monitorización invasiva mediante CAP según las directrices de ese momento. Se realizó una ETT en un plazo de 15 minutos de haber realizado el CAP y el investigador no tuvo acceso a las mediciones del CAP. Las mediciones comparativas se extrajeron de estudios similares obtenidos a partir de una revisión sistemática de la literatura y se añadieron a una base de datos. Se compararon las mediciones simultáneas del GC mediante ETT y CAP. La concordancia entre métodos se evaluó a través del método estadístico de Bland-Altman y de coeficientes de correlación intraclase (CCI). Se incluyeron treinta y cuatro mediciones comparativas en el metaanálisis. Los valores medios del GC obtenidos mediante CAP y ETT fueron de 7,39 l/min y 7.18 l/min, respectivamente. El sesgo fue de 0,21 l/min, siendo los límites inferior y superior de la concordancia de -1,18 l/min y 1.60 l/min; el error porcentual fue del 19,1%, y el CCI entre ambos métodos fue de 0,94. Las mediciones del GC en mujeres embarazadas mediante ETT muestran una excelente concordancia con las obtenidas mediante CAP. Dada su naturaleza no invasiva y su disponibilidad, la ETT podría considerarse como referencia para la validación de otras técnicas relacionadas con el GC en mujeres embarazadas. : ,。(pulmonary artery catheterization,PAC)(cardiac output,CO),,。(transthoracic echocardiography,TTE)CO。PACTTECO。 : meta。2003。PAC。PAC 15 minTTE,PAC。,。TTEPACCO。Bland-Altman(intraclass correlation coefficients,ICC)。 : meta34。PACTTECO7.39 L/min7.18 L/min。-1.18 L/min、1.60 L/min0.21 L/min,19.1%,ICC0.94。 : TTECOPACCO。,TTECO。.

Thioredoxins Play a Crucial Role in Dynamic Acclimation of Photosynthesis in Fluctuating Light.

Sunlight represents the energy source for photosynthesis and plant growth. When growing in the field, plant photosynthesis has to manage strong fluctuations in light intensities. Regulation based on the thioredoxin (Trx) system is believed to ensure light-responsive control of photosynthetic reactions in the chloroplast. However, direct evidence for a role of this system in regulating dynamic acclimation of photosynthesis in fluctuating conditions is largely lacking. In this report we show that the ferredoxin-dependent Trxs m1 and m2 as well as the NADPH-dependent NTRC are both indispensable for photosynthetic acclimation in fluctuating light intensities. Arabidopsis mutants with combined deficiency in Trxs m1 and m2 show wild-type growth and photosynthesis under constant light condition, while photosynthetic parameters are strongly modified in rapidly alternating high and low light. Two independent trxm1m2 mutants show lower photosynthetic efficiency in high light, but surprisingly significantly higher photosynthetic efficiency in low light. Our data suggest that a main target of Trx m1 and m2 is the NADP-malate dehydrogenase involved in export of excess reductive power from the chloroplast. The decreased photosynthetic efficiency in the high-light peaks may thus be explained by a reduced capacity of the trxm1m2 mutants in the rapid light activation of this enzyme. In the ntrc mutant, dynamic responses of non-photochemical quenching of excitation energy and plastoquinone reduction state both were strongly attenuated in fluctuating light intensities, leading to a massive decrease in PSII quantum efficiency and a specific decrease in plant growth under these conditions. This is likely due to the decreased ability of the ntrc mutant to control the stromal NADP(H) redox poise. Taken together, our results indicate that NTRC is indispensable in ensuring the full range of dynamic responses of photosynthesis to optimize photosynthesis and maintain growth in fluctuating light, while Trxs m1 and m2 are indispensable for full activation of photosynthesis in the high-light periods but negatively affect photosynthetic efficiency in the low-light periods of fluctuating light.

Estudio teórico de la distribución catiónica en la capa octaédrica de silicatos laminares

NASA Astrophysics Data System (ADS)

Hernández-Laguna, A.

Los silicatos laminares son unos minerales de gran extensión en la corteza de nuestro y otros planetas, y se ha detectado su presencia en masas de partículas de polvo interplanatario. Están formados por láminas estructuradas en una capa tetraedros de sílice y una de octaédros de oxihidroxido de aluminio. Según el número de capas y la disposición aparecen distintos minerales. Además, también pueden aparecer distintos minerales como consecuencia de la substitución isomórfica de cationes en la capas, en particular, Al(III) por Si en la capa tetraédrica y Fe(III) y/o Mg(II) por Al(III) en la octaédrica. Cuando el catión substituyente presenta un estado de oxidación más bajo que al que substituye genera carga negativa que tiene que neutralizarse con cationes que se disponen en el espacio interlaminar. En este trabajo vamos a estudiar, mediante distintos métodos computacionales, las distribuciones de dichos cationes de substitución en la capa octaédrica de silicatos laminares 2:1 (dos capas tetraédricas y en medio una octaédrica), en particular, en los minerales esmectitas e ilitas. En primer lugar, estudiaremos la distribución de dichos cationes en la capa octaédrica en un modelo de gas reticular por el método de Monte Carlo, minimizando el número de pares de cationes Al, Fe y Mg de nuestro modelo con respecto a los procedentes de resultados espectroscópicos de muestras de minerales. Posteriormente, y mediante un modelo de potenciales empíricos, estudiamos la energética de las distribuciones binarias en dichos minerales, generando unos potenciales de interacción intercambio a dos y tres cationes (extrapolables a cualquier filosilicato) que son la base para una investigación Monte Carlo-"simulated-annealing" en la que se encuentran las transiciones de fase y las estructuras ordenadas, dependiendo dichas estructuras y la temperatura de cambio de fase de la de la naturaleza y concentración de los cationes de substitución. También se han investigado dichas distribuciones mediante métodos mecano-cuánticos DFT.

2000-05-01

Periodic orbits are the central ingredients of modern semiclassical theories and corrections to these are generally nonclassical in origin. We show here that, for the class of generic polygonal billiards, the corrections are predominantly classical in origin owing to the contributions from closed almost-periodic (CAP) orbit families. Furthermore, CAP orbit families outnumber periodic families but have comparable weights. They are hence indispensable for semiclassical quantization.

2007-09-01

Chick imprinting behavior is a good model for the study of learning and memory. Imprinting object is recognized and processed in the visual wulst, and the memory is stored in the intermediate medial mesopallium in the dorsal pallium of the telencephalon. We identified chicken cholecystokinin (CCK)-expressing cells localized in these area. The number of CCK mRNA-positive cells increased in chicks underwent imprinting training, and these cells expressed nuclear Fos immunoreactivity at high frequency in these regions. Most of these CCK-positive cells were glutamatergic and negative for parvalbumin immunoreactivity. Semi-quantitative PCR analysis revealed that the CCK mRNA levels were significantly increased in the trained chicks compared with untrained chicks. In contrast, the increase in CCK- and c-Fos-double-positive cells associated with the training was not observed after closure of the critical period. These results indicate that CCK cells in the dorsal pallium are activated acutely by visual training that can elicit imprinting. In addition, the CCK receptor antagonist significantly suppressed the acquisition of memory. These results suggest that the activation of CCK cells in the visual wulst as well as in the intermediate medial mesopallium by visual stimuli is indispensable for the acquisition of visual imprinting.

Missense suppression in Coprinus lagopus associated wtih a chromosome duplication.

PubMed

Lewis, D; Casselton, L A

1975-05-01

Amongst some 70 recessive suppressors of a met-I mutation in Coprinus lagopus, one unstable suppressor was identified. The unstable suppressor, designated sup-6plus, could be maintained on minimal medium, but was lost within 24h on minimal medium containing more than 1-7 p.p.m. DL-methionine or 0-75 p.p.m. L-methionine. Isolation of hyphal tips from the monokaryotic strain carrying sup-6plus yielded three types of colony: the unstable parental type, the stable met-I auxotroph and a stable prototroph which was slow-growing and inhibited by methionine in the growth medium. This stable sup-6plus type was recovered with difficulty by resolving dikaryons formed between the unstable sup-6plus strain and strains carring the wild-type allele of the suppressor gene. From sexual crosses, neither the unstable nor stable sup-6plus type segregated, only the met-I auxotrophic revertant. The unstable sup-6plus strain is thought to have an extra chromosome carrying the sup-6plus mutation. For vigorous growth the wild-type allele, sup-6, is indispensable and would be carried on the homologous chromosome. The selective pressures on different media account for loss of the duplicated chromosomes. The results are interpreted as missense suppression by a mutant of an indispensable tRNA.

The formation of citizens: the pediatrician's role.

Campos Júnior, Dioclécio

2016-01-01

This review article aims to define the fundamental role of the pediatrician in the formation of citizens in the 21st century. Significant bibliographical contributions produced by neuroscience, ecology, and epigenetics in the early childhood scenario. Many diseases that impair the lives of adults result from severe and often uncontrollable disorders that occur in early childhood, an irreplaceable period for the safe construction of the human brain, personality, and intelligence. There is noteworthy scientific evidence that has become unquestionable, according to which abuse and neglect and other forms of violence to which children are exposed during the course of their lives, are the genesis of many physical ailments and other mental diseases, including depressive morbidity and schizophrenia. Conversely, it is also emphasized that healthy practices such as reading and listening to/playing music are able to intensively contribute to the exercise of cognitive capacity inherent to this period of life, as a prerequisite for the acquisition of learning indispensable to the high educational performance during the schooling period. In the light of the disclosed scientific evidence, the pediatrician emerges as the most differentiated professional to provide preventive and curative care indispensable to the skilled formation of a healthy citizen.

Molecular cytogenetics: an indispensable tool for cancer diagnosis.

PubMed

Wan, Thomas Sk; Ma, Edmond Sk

2012-01-01

Cytogenetic aberrations may escape detection or recognition in traditional karyotyping. The past decade has seen an explosion of methodological advances in molecular cytogenetics technology. These cytogenetics techniques add color to the black and white world of conventional banding. Fluorescence in-situ hybridization (FISH) study has emerged as an indispensable tool for both basic and clinical research, as well as diagnostics, in leukemia and cancers. FISH can be used to identify chromosomal abnormalities through fluorescent labeled DNA probes that target specific DNA sequences. Subsequently, FISH-based tests such as multicolor karyotyping, comparative genomic hybridization (CGH) and array CGH have been used in emerging clinical applications as they enable resolution of complex karyotypic aberrations and whole global scanning of genomic imbalances. More recently, crossspecies array CGH analysis has also been employed in cancer gene identification. The clinical impact of FISH is pivotal, especially in the diagnosis, prognosis and treatment decisions for hematological diseases, all of which facilitate the practice of personalized medicine. This review summarizes the methodology and current utilization of these FISH techniques in unraveling chromosomal changes and highlights how the field is moving away from conventional methods towards molecular cytogenetics approaches. In addition, the potential of the more recently developed FISH tests in contributing information to genetic abnormalities is illustrated.

Bioinformatics: indispensable, yet hidden in plain sight?

PubMed

Bartlett, Andrew; Penders, Bart; Lewis, Jamie

2017-06-21

Bioinformatics has multitudinous identities, organisational alignments and disciplinary links. This variety allows bioinformaticians and bioinformatic work to contribute to much (if not most) of life science research in profound ways. The multitude of bioinformatic work also translates into a multitude of credit-distribution arrangements, apparently dismissing that work. We report on the epistemic and social arrangements that characterise the relationship between bioinformatics and life science. We describe, in sociological terms, the character, power and future of bioinformatic work. The character of bioinformatic work is such that its cultural, institutional and technical structures allow for it to be black-boxed easily. The result is that bioinformatic expertise and contributions travel easily and quickly, yet remain largely uncredited. The power of bioinformatic work is shaped by its dependency on life science work, which combined with the black-boxed character of bioinformatic expertise further contributes to situating bioinformatics on the periphery of the life sciences. Finally, the imagined futures of bioinformatic work suggest that bioinformatics will become ever more indispensable without necessarily becoming more visible, forcing bioinformaticians into difficult professional and career choices. Bioinformatic expertise and labour is epistemically central but often institutionally peripheral. In part, this is a result of the ways in which the character, power distribution and potential futures of bioinformatics are constituted. However, alternative paths can be imagined.

Analyzing the sensitivity of a flood risk assessment model towards its input data

2016-11-01

The Small Island Developing States are characterized by an unstable economy and low-lying, densely populated cities, resulting in a high vulnerability to natural hazards. Flooding affects more people than any other hazard. To limit the consequences of these hazards, adequate risk assessments are indispensable. Satisfactory input data for these assessments are hard to acquire, especially in developing countries. Therefore, in this study, a methodology was developed and evaluated to test the sensitivity of a flood model towards its input data in order to determine a minimum set of indispensable data. In a first step, a flood damage assessment model was created for the case study of Annotto Bay, Jamaica. This model generates a damage map for the region based on the flood extent map of the 2001 inundations caused by Tropical Storm Michelle. Three damages were taken into account: building, road and crop damage. Twelve scenarios were generated, each with a different combination of input data, testing one of the three damage calculations for its sensitivity. One main conclusion was that population density, in combination with an average number of people per household, is a good parameter in determining the building damage when exact building locations are unknown. Furthermore, the importance of roads for an accurate visual result was demonstrated.

Transgenic animals have been indispensable in elucidating and deciphering mechanisms underlying various biological phenomena. In regeneration, transgenic animals expressing fluorescent protein genes have been crucial for identifying the source cells for regeneration and the mechanism of blastema formation. Animals are usually generated by manipulating their genome using various techniques at/in one cell embryo/fertilized egg stage. Here, we describe the generation of germline transgenic axolotls (Ambystoma mexicanum) using the I-SceI meganuclease and Tol2 transposase.

Radioisotopes can be produced by reactors and accelerators. For certain isotopes there could be an advantage to a certain production method. However, nowadays many reports suggest, that useful isotopes needed in medicine, industry and research could be produced efficiently and dependence on reactors using enriched U-235 may be eliminated. In my view reactors and accelerators will continue to play their role side by side in the supply of suitable and economical sources of isotopes.

Cervical length screening by transvaginal sonography (TVS) has been shown to be a good predictive test for spontaneous preterm birth (PTB) in symptomatic singleton pregnancy with threatened preterm labor (PTL). The aim of this review and meta-analysis of individual participant data was to evaluate the effect of knowledge of the TVS cervical length (CL) in preventing PTB in singleton pregnancies presenting with threatened PTL. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register and the Cochrane Complementary Medicine Field's Trials Register (May 2016) and reference lists of retrieved studies. Selection criteria included randomized controlled trials of singleton gestations with threatened PTL randomized to management based mainly on CL screening (intervention group), or CL screening with no knowledge of results or no CL screening (control group). Participants included women with singleton gestations at 23 + 0 to 36 + 6 weeks with threatened PTL. We contacted corresponding authors of included trials to request access to the data and perform a meta-analysis of individual participant data. Data provided by the investigators were merged into a master database constructed specifically for the review. The primary outcome was PTB < 37 weeks. Summary measures were reported as relative risk (RR) or as mean difference (MD) with 95% CI. Three trials including a total of 287 singleton gestations with threatened PTL between 24 + 0 and 35 + 6 weeks were included in the meta-analysis, of which 145 were randomized to CL screening with knowledge of results and 142 to no knowledge of CL. Compared with the control group, women who were randomized to the known CL group had a significantly lower rate of PTB < 37 weeks (22.1% vs 34.5%; RR, 0.64 (95% CI, 0.44-0.94); three trials; 287 participants) and a later gestational age at delivery (MD, 0.64 (95% CI, 0.03-1.25) weeks; MD, 4.48 (95% CI, 1.18-8.98) days; three trials; 287 participants). All other outcomes for which there were available data were similar in the two groups. There is a significant association between knowledge of TVS CL and lower incidence of PTB and later gestational age at delivery in symptomatic singleton gestations with threatened PTL. Given that in the meta-analysis we found a significant 36% reduction in the primary outcome, but other outcomes were mostly statistically similar, further study needs to be undertaken to understand better whether the predictive characteristics of CL screening by TVS can be translated into better clinical management and therefore better outcomes and under what circumstances.

CRIBADO MEDIANTE LA LONGITUD CERVICAL PARA LA PREVENCIÓN DEL PARTO PRETÉRMINO EN EMBARAZOS CON FETO ÚNICO Y RIESGO DE PARTO PREMATURO: REVISIÓN SISTEMÁTICA Y METAANÁLISIS DE ENSAYOS CONTROLADOS ALEATORIZADOS HACIENDO USO DE LOS DATOS INDIVIDUALES DE LAS PACIENTES: RESUMEN OBJETIVO: El cribado mediante la longitud cervical obtenida con ecografía transvaginal (ETV) ha demostrado ser una buena prueba para la predicción del parto pretérmino espontáneo (PPTE) en embarazos con feto único sintomáticos debido a la amenaza de parto pretérmino (PPT). El objetivo de esta revisión y metaanálisis de los datos de participantes individuales fue evaluar el efecto de medir la longitud cervical (LC) mediante ETV con el fin de prevenir el parto prematuro en embarazos únicos con amenaza de PPT. MÉTODOS: Se realizaron búsquedas en los ficheros de ensayos de Cochrane Pregnancy and Childbirth Group y Complementary Medicine Field (mayo de 2016), y en las listas de referencias de los estudios encontrados. Los criterios de selección incluyeron ensayos controlados aleatorizados de embarazos con feto único y riesgo de PPT con aleatorización de la paciente basada principalmente en el cribado mediante la LC (grupo de intervención), el cribado mediante la LC sin conocimiento de los resultados, o sin cribado de LC (grupo de control). Las participantes fueron mujeres embarazadas con feto único desde las 23 + 0 hasta las 36 + 6 semanas y con riesgo de PPT. Se estableció contacto con los autores de los ensayos incluidos para solicitar el acceso a los datos y llevar a cabo un metaanálisis de los datos de las participantes individualmente. Los datos proporcionados por los investigadores se agregaron a una base de datos maestra creada específicamente para esta revisión. El resultado primario fue el PPTE < 37 semanas. Las medidas resumen se reportaron como riesgo relativo (RR) o como diferencia de medias (DM) con IC del 95%. En el metaanálisis se incluyeron tres ensayos con un total de 287 embarazos con feto único y riesgo de PPT entre 24 + 0 y 35 + 6 semanas, de los cuales 145 fueron asignados al azar a un cribado mediante la LC con conocimiento de los resultados y 142 a aquellos para los que se desconocía la LC. En comparación con el grupo control, las mujeres que fueron asignadas aleatoriamente al grupo en el que se conocía la LC tuvieron una tasa de parto prematuro a < 37 semanas significativamente menor (22,1% vs. 34,5%; RR 0,64 (IC 95%, 0,44-0,94); 3 ensayos; 287 participantes ) y una edad gestacional al momento del parto más tardía (DM 0,64 (IC 95%, 0.03-1.25) semanas; DM 4,48 (IC 95%, 1,18-8,98) días; 3 ensayos; 287 participantes). El resto de los resultados para los cuales había datos disponibles fueron similares en ambos grupos. Existe una asociación significativa entre el conocimiento de la LC obtenida mediante ETV y una menor incidencia de PPTE y edad gestacional más tardía en el momento del parto en embarazos con feto único sintomáticos debido al riesgo de parto pretérmino (PPT). Teniendo en cuenta que en el metaanálisis se encontró una reducción significativa del 36% en el resultado primario, pero que los otros resultados fueron estadísticamente similares en su mayoría, serán necesarios más estudios para entender mejor si las propiedades predictivas del cribado mediante la LC obtenida con ETV se pueden traducir en una mejor atención clínica y por lo tanto mejores resultados dependiendo de las circunstancias. :META: : ,(preterm labor,PTL),(transvaginal sonography,TVS)(spontaneous preterm birth,PTB)。metaPTL,TVS(cervical length,CL)PTB。 : CochraneCochrane(20165)。PTL,CL()CLCL()。23 + 036+6PTL。,,meta。。37PTB。(relative risk,RR)95%CI(mean difference,MD)。 : meta3,28724 + 035+6PTL,145CL,142CL。,CL37PTB[22.1%34.5%;RR,0.64(95% CI,0.44 ~ 0.94);3;287],[MD,0.64(95% CI,0.03 ~ 1.25);MD,4.48(95% CI,1.18 ~ 8.98);3;287]。2,。 : PTL,TVS CLPTB。meta36%,,,TVSCL,。.

Introducción: la infertilidad es un problema global en aumento. Se estima que aproximadamente un 15% de las parejas en edad reproductiva tiene dificultades a la hora de concebir. De estas, alrededor de la mitad presentan uno o varios factores masculinos asociados a infertilidad o subfertilidad, aislados o en combinación con problemas de origen femenino. Durante la última década se ha empezado a estudiar la infertilidad desde una perspectiva multifactorial, considerando las interacciones y conexiones entre diferentes situaciones genéticas, epigenéticas, bioquímicas y fisiológicas del paciente.Objetivo: la presente revisión pretende describir mecanismos epigenéticos que pueden ser modulados mediante aspectos nutricionales y que están relacionados con la etiología de la infertilidad masculina y con la herencia transgeneracional de este fenotipo.Material y métodos: se ha realizado una extensa búsqueda de publicaciones científicas en las principales bases de datos electrónicas especializadas: NBCI, Elsevier, Scielo, Scirus y Science Direct.Resultados y conclusión: varios trabajos que muestran la importancia del estado nutricional en la fertilidad del hombre y, más específicamente, la capacidad de los componentes de la dieta para modificar los perfiles epigenéticos que no únicamente pueden afectar a su fertilidad, sino que también pueden ser transmitidos a la descendencia mediante lo que se ha denominado herencia transgeneracional, ocasionándoles problemas de salud diversos entre los que también se hallan problemas en la fertilidad.

Effect of dietary soybean oil and soybean protein concentration on the concentration of digestible amino acids in soybean products fed to growing pigs.

PubMed

Cervantes-Pahm, S K; Stein, H H

2008-08-01

An experiment was conducted to measure the effect of adding soybean oil to soybean meal (SBM) and soy protein concentrate (SPC) on apparent (AID) and standardized (SID) ileal digestibility of CP and AA by growing pigs. A second objective was to compare AID and SID of AA in a new high-protein variety of full fat soybeans (FFSB) to values obtained in other soybean products. Commercial sources of FFSB (FFSB-CV), SBM, and SPC, and of a new high-protein variety of FFSB (FFSB-HP) were used in the experiment. Four diets were prepared using each soybean product as the sole source of CP and AA in 1 diet. Two additional diets were formulated by adding soybean oil (7.55 and 7.35%, respectively) to the diets containing SBM and SPC. A nitrogen-free diet was also used to measure basal endogenous losses of CP and AA. The 2 sources of FFSB were extruded at 150 degrees C before being used in the experiment. Seven growing barrows (initial BW = 26.2 kg) were prepared with a T-cannula in the distal ileum and allotted to a 7 x 7 Latin square design. Ileal digesta were collected from the pigs on d 6 and 7 of each period. All digesta samples were lyophilized and analyzed for DM, CP, AA, and chromium, and values for AID and SID of CP and AA were calculated. The addition of oil improved (P < 0.05) the SID of most indispensable AA in SBM and SPC.

However, the SID for most AA in FFSB-HP was similar to SBM with oil and SPC, but these values were lower (P < 0.05) than in SPC with oil.

β-casein is a protein which forms micelles in aqueous solvents. The magnitude and the range of the weight-average interactions between the diverse solute particles are infrared from small-angle neutron scattering measurements made on various β-casein solutions. Well above the critical micelle concentration (CMC), these interactions are repulsive. They weaken with decreasing protein concentration, and finally become strongly attractive near the CMC. Although indispensable for micelle formation this fact has never been reported so far.

Genetic diversity within species is highly significant during their adaptation to environmental changes and, consequently, for their long-term survival. The genetic variability of species is also the basis for the evolution of higher levels of biodiversity, the evolution of species, and it might be an indispensible prerequisite for the functioning of our biosphere. Studies which promote understanding of the maintenance and the functional aspects of biodiversity at any level are therefore essential for the future welfare of mankind.

Introduction Since the end of the 1990s, globalization has become a common term, facilitated by the social media of today and the growing public awareness of life-threatening problems common to all people, such as global warming, global security and global divides. Review For the main parameters of health like the burden of disease, life expectancy and healthy life expectancy, extreme discrepancies are observed across the world. Infant mortality, malnutrition and high fertility go hand in hand. Civil society, as an indispensable activator of public health development, mainly represented by non-governmental organisations (NGOs), is characterised by a high degree of fragmentation and lack of public accountability. The World Federation of Public Health Associations is used as an example of an NGO with a global mission and fostering regional cooperation as an indispensable intermediate level. The lack of a globally valid terminology of basic public health functions is prohibitive for coordinated global and regional efforts. Attempts to harmonise essential public health functions, services and operations are under way to facilitate communication and mutual understanding. Recommendations 1) Given the limited effects of the Millennium Development Goal agenda, the Post-2015 Development Goals should focus on integrated regional development. 2) A code of conduct for NGOs should be urgently developed for the health sector, and NGOs should be registered and accredited. 3) The harmonisation of the basic terminology for global public health essentials should be enhanced.

The crystal structures of the Na(+)- and Li(+)-bound NtpK rings of Enterococcus hirae V-ATPase have been obtained. The coupling ion (Na(+) or Li(+)) was surrounded by five oxygen atoms contributed by residues T64, Q65, Q110, E139, and L61, and the hydrogen bonds of the side chains of Q110, Y68, and T64 stabilized the position of the E139 γ carboxylate essential for ion occlusion (PDB accession numbers 2BL2 and 2CYD). We previously indicated that an NtpK mutant strain (E139D) lost tolerance to sodium but not to lithium at alkaline pHs and suggested that the E139 residue is indispensable for the enzymatic activity of E. hirae V-ATPase linked with the sodium tolerance of this bacterium. In this study, we examined the activities of V-ATPase in which these four residues, except for E139, were substituted. The V-ATPase activities of the Q65A and Y68A mutants were slightly retained, but those of the T64A and Q110A mutants were negligible. Among the residues, T64 and Q110 are indispensable for the ion coupling of E. hirae V-ATPase, in addition to the essential residue E139.

Virtual screening is an indispensable tool to cope with the massive amount of data being tossed by the high throughput omics technologies. With the objective of enhancing the automation capability of virtual screening process a robust portal termed MegaMiner has been built using the cloud computing platform wherein the user submits a text query and directly accesses the proposed lead molecules along with their drug-like, lead-like and docking scores. Textual chemical structural data representation is fraught with ambiguity in the absence of a global identifier. We have used a combination of statistical models, chemical dictionary and regular expression for building a disease specific dictionary. To demonstrate the effectiveness of this approach, a case study on malaria has been carried out in the present work. MegaMiner offered superior results compared to other text mining search engines, as established by F score analysis. A single query term 'malaria' in the portlet led to retrieval of related PubMed records, protein classes, drug classes and 8000 scaffolds which were internally processed and filtered to suggest new molecules as potential anti-malarials. The results obtained were validated by docking the virtual molecules into relevant protein targets. It is hoped that MegaMiner will serve as an indispensable tool for not only identifying hidden relationships between various biological and chemical entities but also for building better corpus and ontologies.

Thermodynamic approach to oxygen delivery in vivo by natural and artificial oxygen carriers.

PubMed

Bucci, Enrico

2009-06-01

Oxygen is a toxic gas, still indispensable to aerobic life. This paper explores how normal physiology uses the physico-chemical and thermodynamic characteristics of oxygen for transforming a toxic gas into a non toxic indispensable metabolite. Plasma oxygen concentration is in the range of 10(-5) M, insufficient to sustain metabolism. Oxygen carriers, present in blood, release oxygen into plasma, thereby replacing consumed oxygen and buffering PO(2) near their P(50). They are the natural cell-bound carriers, like hemoglobin inside red cells, myoglobin inside myocytes, and artificial cell-free hemoglobin-based oxygen carriers (HBOC) dissolved in plasma. Metabolic oxygen replacement can be defined as cell-bound and cell-free delivery. Cell-bound delivery is retarded by the slow diffusion of oxygen in plasma and interstitial fluids. The 40% hematocrit of normal blood compensates for the delay, coping with the fast oxygen consumption by mitochondria. Facilitated oxygen diffusion by HBOCs corrects for the slow diffusion, making cell-free delivery relatively independent from P(50). At all oxygen affinities, HBOCs produce hyperoxygenations that are compensated by vasoconstrictions. There is a strict direct correlation between the rate of oxygen replacement and hemoglobin content of blood. The free energy loss of the gradient adds a relevant regulation of tissues oxygenation. Oxygen is retained intravascularly by the limited permeability to gases of vessel walls.

Chondroitin sulfate (CS)/chondroitin (Chn) chains are indispensable for embryonic cell division and cytokinesis in the early developmental stages in Caenorhabditis elegans and mice, whereas heparan sulfate (HS) is essential for axon guidance during nervous system development. These data indicate that the fundamental functions of CS and HS are conserved from worms to mammals and that the function of CS/Chn differs from that of HS. Although previous studies have shown that C. elegans produces HS and non-sulfated Chn, whether the organism produces CS remains unclear. Here, we demonstrate that C. elegans produces a small amount of 4-O-sulfated Chn and report the identification of C41C4.1, an orthologue of the human chondroitin 4-O-sulfotransferase gene. Loss of C41C4.1 in C. elegans resulted in a decline in 4-O-sulfation of CS and an increase in the number of sulfated units in HS. C41C4.1 deletion mutants exhibited reduced survival rates after synchronization with sodium hypochlorite. Collectively, these results show for the first time that CS glycans are present in C. elegans and that the Chn 4-O-sulfotransferase responsible for the sulfation plays an important role in protecting nematodes from oxidative stress. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

Eccrine sweat gland development and sweat secretion

PubMed Central

Cui, Chang-Yi; Schlessinger, David

2017-01-01

Eccrine sweat glands help to maintain homoeostasis, primarily by stabilizing body temperature. Derived from embryonic ectoderm, millions of eccrine glands are distributed across human skin and secrete litres of sweat per day. Their easy accessibility has facilitated the start of analyses of their development and function. Mouse genetic models find sweat gland development regulated sequentially by Wnt, Eda and Shh pathways, although precise subpathways and additional regulators require further elucidation. Mature glands have two secretory cell types, clear and dark cells, whose comparative development and functional interactions remain largely unknown. Clear cells have long been known as the major secretory cells, but recent studies suggest that dark cells are also indispensable for sweat secretion. Dark cell-specific Foxa1 expression was shown to regulate a Ca2+-dependent Best2 anion channel that is the candidate driver for the required ion currents. Overall, it was shown that cholinergic impulses trigger sweat secretion in mature glands through second messengers – for example InsP3 and Ca2+ – and downstream ion channels/transporters in the framework of a Na+-K+-Cl− cotransporter model. Notably, the microenvironment surrounding secretory cells, including acid–base balance, was implicated to be important for proper sweat secretion, which requires further clarification. Furthermore, multiple ion channels have been shown to be expressed in clear and dark cells, but the degree to which various ion channels function redundantly or indispensably also remains to be determined.

We constructed nine deletion mutants of NAD+-dependent DNA ligase from Aquifex pyrophilus to characterize the functional domains. All of DNA ligase deletion mutants were analyzed in biochemical assays for NAD+-dependent self-adenylation, DNA binding, and nick-closing activity. Although the mutant lsub1 (91-362) included the active site lysine (KxDG), self-adenylation was not shown. However, the mutants lsub6 (1-362), lsub7 (1-516), and lsub9 (1-635) showed the same adenylation activity as that of wild type. The lsub5 (91-719), which has the C-terminal domain (487-719) as to lsub4 (91-486), showed minimal adenylation activity. These results suggest that the presence of N-terminal 90 residues is essential for the formation of an enzyme-AMP complex, while C-terminal domain (487-719) appears to play a minimal role in adenylation. It was found that the presence of C-terminal domain (487-719) is indispensable for DNA binding activity of lsub5 (91-719). The mutant lsub9 (1-635) showed reduced DNA binding activity compared to that of wild type, suggesting the contribution of the domain (636-719) for the DNA binding activity. Thus, we concluded that the N-terminal 90 residues and C-terminal domain (487-719) of NAD+-dependent DNA ligase from A. pyrophilus are mutually indispensable for binding of DNA substrate.

Potential impact of the digestible indispensable amino acid score as a measure of protein quality on dietary regulations and health

PubMed Central

Marinangeli, Christopher P F; House, James D

2017-01-01

Abstract Regulatory frameworks for protein content claims in Canada and the United States are underpinned by the protein efficiency ratio and protein digestibility-corrected amino acid score (PDCAAS), respectively, which are used to assess the protein quality of a given food. The digestible indispensable amino acid score (DIAAS) is a novel approach to measuring the protein quality of foods and is supported by the Food and Agriculture Organization of the United Nations. Methodological concerns about the PDCAAS are addressed by the DIAAS through introduction of the use of ileal amino acid digestibility coefficients and untruncated protein scores. However, before the DIAAS is widely adopted within regulatory frameworks, a comprehensive assessment is required. Accordingly, this review addresses the potential impact of the DIAAS on regulation, communication, and public health, as well as knowledge gaps, analytical challenges, and cost of implementation. A pragmatic approach to addressing protein quality is advocated by suggesting the use of conservative coefficients of digestibility that are derived from in vitro methods. Before adopting the DIAAS as a framework for supporting protein content claims, updated food-related regulations and policies should also be evaluated through a lens that anticipates the impact on consumer-facing nutrition communication, the adoption of dietary patterns that are nutritionally adequate, and a food value chain that fosters a spirit of food and nutritional innovation.

INTRODUCTION: Parenteral nutrition (PN) formulations are commonly individualized, since their standardization appears inadequate for the pediatric population. This study aimed to evaluate the nutritional state and the reasons for PN individualization in pediatric patients using PN, hospitalized in a tertiary hospital in Campinas, São Paulo. METHODS: This longitudinal study comprised patients using PN followed by up to 67 days. Nutritional status was classified according to the criteria established by the World Health Organization (WHO) (2006) and WHO (2007). The levels of the following elements in blood were analyzed: sodium, potassium, ionized calcium, chloride, magnesium, inorganic phosphorus, and triglycerides (TGL). Among the criteria for individualization, the following were considered undeniable: significant reduction in blood levels of potassium (<3mEq/L), sodium (<125mEq/L), magnesium (<1mEq/L), phosphorus (<1.5mEq/L), ionic calcium (<1mmol), and chloride (<90mEq/L), or any value above the references. RESULTS: Twelve pediatric patients aged 1 month to 15 years were studied (49 individualizations). Most patients were classified as malnourished. It was observed that 74/254 (29.2%) of examinations demanded individualized PN for indubitable reasons. CONCLUSION: The nutritional state of patients was considered critical in most cases. Thus, the individualization performed in the beginning of PN for energy protein adequacy was indispensable. In addition, the individualized PN was indispensable in at least 29.2% of PN for correction of alterations found in biochemical parameters. PMID:25510996

Distinct mechanisms act in concert to mediate cell cycle arrest.

In response to DNA damage, cells arrest at specific stages in the cell cycle. This arrest must fulfill at least 3 requirements: it must be activated promptly; it must be sustained as long as damage is present to prevent loss of genomic information; and after the arrest, cells must re-enter into the appropriate cell cycle phase to ensure proper ploidy. Multiple molecular mechanisms capable of arresting the cell cycle have been identified in mammalian cells; however, it is unknown whether each mechanism meets all 3 requirements or whether they act together to confer specific functions to the arrest. To address this question, we integrated mathematical models describing the cell cycle and the DNA damage signaling networks and tested the contributions of each mechanism to cell cycle arrest and re-entry. Predictions from this model were then tested with quantitative experiments to identify the combined action of arrest mechanisms in irradiated cells. We find that different arrest mechanisms serve indispensable roles in the proper cellular response to DNA damage over time: p53-independent cyclin inactivation confers immediate arrest, whereas p53-dependent cyclin downregulation allows this arrest to be sustained. Additionally, p21-mediated inhibition of cyclin-dependent kinase activity is indispensable for preventing improper cell cycle re-entry and endoreduplication. This work shows that in a complex signaling network, seemingly redundant mechanisms, acting in a concerted fashion, can achieve a specific cellular outcome.

In cells, microtubules (MTs) are nucleated at MT-organizing centers (MTOCs). The centrosome-based MTOCs organize radial MT arrays which are often not optimal for polarized trafficking. A recently discovered subset of non-centrosomal MTs nucleated at the Golgi has proven to be indispensable for the Golgi organization, post-Golgi trafficking and cell polarity. Here, we summarize the history of this discovery, known molecular prerequisites of MT nucleation at the Golgi and unique functions of Golgi-derived MTs. PMID:23821162
