Bia go Halainn  

Digital Repository Infrastructure Vision for European Research (DRIVER)

I love food, I eat it everyday, and I think that is reason enough to be interested in it enough to write about it. I support the work of local restaurants, and am in charge of marketing at what I consider to be one of the finest gastronomic gafs in the west of Ireland, plainly because I love everything that is Ard Bia – It is the most idyllic culinary hub situated in one of the most iconic buildings in Galway. Ard Bia and Richie McCarthy are passionate about the same principles, excel...

Use of electrocardiogram (ECG) electrodes for Bioelectrical Impedance Analysis (BIA)  

International Nuclear Information System (INIS)

BIA is a safe, noninvasive, portable and relatively inexpensive method of estimating body composition that is practical and suitable for individual use and large-scale studies. However, the cost of the electrodes recommended by some BIA manufacturers is too high for developing countries; where very often the long and complicated process of importation reduces the time they can be used. The purpose of this study was to evaluate the use of two types of ECG electrodes (2290 and 2228 by 3M®) in BIA measurements to decrease the costs of the test. The results showed that the 2228 ECG electrodes can be used in BIA measurements for adult's body composition assessment. These electrodes are available in the domestic market and their costs are 92% lower than the electrodes recommended by manufacturer. The results show a new cost-benefit relation for BIA method and make this a more accessible tool for individual tests, large-scale researches and studies in the community.

In Vivo and In Vitro Evidence that TtgV Is the Specific Regulator of the TtgGHI Multidrug and Solvent Efflux Pump of Pseudomonas putida  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The TtgGHI efflux pump of Pseudomonas putida DOT-T1E plays a key role in the innate and induced tolerance of this strain to aromatic hydrocarbons and antibiotics. The ttgGHI operon is expressed constitutively from two overlapping promoters in the absence of solvents and at a higher level in their presence, but not in response to antibiotics. Adjacent to the ttgGHI operon is the divergently transcribed ttgVW operon. In TtgV-deficient backgrounds, although not in a TtgW-deficient background, ex...

Q-site occupancy defines heme heterogeneity in Escherichia coli nitrate reductase A (NarGHI).  

Science.gov (United States)

The membrane subunit (NarI) of Escherichia coli nitrate reductase A (NarGHI) contains two b-type hemes, both of which are the highly anisotropic low-spin type. Heme bD is distal to NarGH and constitutes part of the quinone binding and oxidation site (Q-site) through the axially coordinating histidine-66 residue and one of the heme bD propionate groups. Bound quinone participates in hydrogen bonds with both the imidazole of His66 and the heme propionate, rendering the EPR spectrum of the heme bD sensitive to Q-site occupancy. As such, we hypothesize that the heterogeneity in the heme bD EPR signal arises from the differential occupancy of the Q-site. In agreement with this, the heterogeneity is dependent upon growth conditions but is still apparent when NarGHI is expressed in a strain lacking cardiolipin. Furthermore, this heterogeneity is sensitive to Q-site variants, NarI-G65A and NarI-K86A, and is collapsible by the binding of inhibitors. We found that the two main gz components of heme bD exhibit differences in reduction potential and pH dependence, which we posit is due to differential Q-site occupancy. Specifically, in a quinone-bound state, heme bD exhibits an Em,8 of -35 mV and a pH dependence of -40 mV pH(-1). In the quinone-free state, however, heme bD titrates with an Em,8 of +25 mV and a pH dependence of -59 mV pH(-1). We hypothesize that quinone binding modulates the electrochemical properties of heme bD as well as its EPR properties. PMID:24592999

Preliminary bioelectrical impedance analysis (BIA) equation for body composition assessment in young females from Colombia  

International Nuclear Information System (INIS)

A previous study showed that reported BIA equations for body composition are not suitable for Colombian population. The purpose of this study was to develop and validate a preliminary BIA equation for body composition assessment in young females from Colombia, using hydrodensitometry as reference method. A sample of 30 young females was evaluated. Inclusion and exclusion criteria were defined to minimize the variability of BIA. Height, weight, BIA, residual lung volume (RV) and underwater weight (UWW) were measured. A preliminary BIA equation was developed (r2 = 0.72, SEE = 2.48 kg) by stepwise multiple regression with fat-free mass (FFM) as dependent variable and weight, height and impedance measurements as independent variables. The quality of regression was evaluated and a cross-validation against 50% of sample confirmed that results obtained with the preliminary BIA equation is interchangeable with results obtained with hydrodensitometry (r2 = 0.84, SEE = 2.62 kg). The preliminary BIA equation can be used for body composition assessment in young females from Colombia until a definitive equation is developed. The next step will be increasing the sample, including a second reference method, as deuterium oxide dilution (D2O), and using multi-frequency BIA (MF-BIA). It would also be desirable to develop equations for males and other ethnic groups in Colombia.

Bioelectrical impedance analysis (BIA) equations validation against hydrodensitometry in a Colombian population  

International Nuclear Information System (INIS)

Several studies have shown that the accuracy of BIA results depends of ethnicity, age, gender, hormonal and genetic variations and, so far, there are not specific equations for Colombian population. The purpose was to evaluate reported BIA equations to determine their usefulness in body composition assessment in young females from Colombia using hydrodensitometry as the reference method. A sample of 30 young females was evaluated. Inclusion and exclusion criteria were defined to minimize the variability of BIA. Height, weight, multi-frequency BIA, residual lung volume (RV) and underwater weight (UWW) were measured. Five BIA equations met the inclusion criteria of this study. Three equations overestimated and two equations underestimated body fat (BF). Paired Student t-test and Bland and Altman analysis (p<0.05) showed significant differences in four BIA equations. However, all standard error of estimate (SEE) to BF was greater than 2.7 kg. This study showed that the five selected BIA equations are not valid for estimation of body composition in young females from Colombia. It is recommended to develop BIA equations to improve BF fat assessment in our population.

Forecasting DNI and GHI based on the WRF model. An evaluation study in Andalusia (Southern Spain)  

Energy Technology Data Exchange (ETDEWEB)

In this work, we evaluate the reliability of GHI and DNI forecast based on the WRF mesoscale atmospheric model in Andalusia (Southern Spain). Particularly, the role of the spatial resolution of the model set up and the use of a spatial-averaging post-processing step was analyzed. To this end, a set of two-days-ahead one-year-length integrations, with different spatial resolutions (1, 3, 9 and 27 km) were evaluated. Results showed, firstly, that an increment in the spatial resolution does not enhance the reliability of the model forecasts, except under clear sky conditions. Secondly, that, in general, an spatial averaging of the solar forecasts corresponding to the grid points surrounding the location of interest provides a notable improvement in the forecasting skills. The most significant improvement is found when forecasts corresponding to an area of about 100 by 100 km are averaged. The role of the WRF model cloud representation in the former results is discussed. (orig.)

Alterations in Growth Related Genes (GH-I, IGF-I and IGF-II Expression with Acute Copper Exposure in Rainbow Trout  

Directory of Open Access Journals (Sweden)

Full Text Available In this study, the acute effects of copper (CuSO4.5H2O on the expression of Growth Hormone-I (GH-I and Insulin like Growth Factors I and II (IGF-I and IGF-II were investigated in rainbow trout (Oncorhynchus mykiss muscle tissue. For this purpose, rainbow trout were exposed to 100 ?g L-1 (Sublethal concentration copper sulfate in moderately hard freshwater. After 6, 12, 24 and 48 h of treatment, expression of white muscle GH-I, IGF-I and IGF-II mRNAs were measured by means of quantitative real-time PCR. During the exposure experiments, no mortalities occurred. All mRNA levels significantly decreased after copper administration (p<0.05. The results indicate that short term copper exposure suppresses the mRNA expression levels of GH-I, IGF-I and IGF-II in rainbow trout muscles.

TtgV Bound to a Complex Operator Site Represses Transcription of the Promoter for the Multidrug and Solvent Extrusion TtgGHI Pump  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The TtgGHI efflux pump of Pseudomonas putida extrudes a variety of antibiotics and solvents. We show that the ttgGHI operon is transcribed in vitro and in vivo from a single promoter and not from two overlapping promoters as previously proposed. The expression of this promoter is controlled by the TtgV repressor, whose operator expands through four helical turns that overlap the ?10 region of the promoter. We also show that TtgV is released from its operator on binding of effectors such as ...

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents descriptions of some interesting species of the Laboulbeniales collected by the author in the Bia?owie?a Forest and its foreland (NE Poland in the period 1994-1998. Among them are 18 determined species new for Poland, four new for science (Corethromyces bialowiezensis sp.n. on Tachyporus solutus, Cryptandromyces bryaxidis sp.n. on Bryaxis bulbifer, Euphoriomyces unilateralis sp.n. on Agathidium atrum, and Phaulomyces ptilii sp.n. on Ptilium affine, and two or three species new for Europe (Peyritschiella geminata Thaxter, Zodiomyces subseriatus Thaxter and perhaps Laboulbenia epithricis Thaxter. Four species are probably new for science but the collected material is too scanty to describe them. Additionally, details concerning morphology or systematic position of some species known already from Poland are supplemented. These data essentially complemented a recent description of Polish species of the group (Majewski 1994.

Synthesis, microsome-mediated metabolism, and identification of major metabolites of environmental pollutant naphtho(8,1,2-ghi)chrysene  

Energy Technology Data Exchange (ETDEWEB)

Naphtho(8,1,2-ghi)chrysene, commonly known as naphtho(1,2-e)pyrene (N(1,2-e)P) is a widespread environmental pollutant, identified in coal tar extract, air borne particulate matter, marine sediment, cigarette smoke condensate, and vehicle exhaust. Herein, we determined the ability of rat liver microsomes to metabolize N(1,2-e)P and an unequivocal assignment of the metabolites by comparing them with independently,synthesized standards. We developed the synthesis of both the fjord region and the K-region dihydrodiols and various phenolic derivatives for metabolite identification. In summary, N(1,2-e)P trans-11, 12-dihydrodiol was the major metabolite formed along with N(1,2-e)P 4,5-trtins-dihydrodiol and 12-OH-N(1,2-e)P on exposure of rat liver microsomes to N(1,2-e)P. The presence of N(1,2-e)P in the environment and formation of fjord region dihydrodiol 14 as a major metabolite in in vitro metabolism studies strongly suggest the role of N(1,2-e)P as a potential health hazard.

A protein-dependent riboswitch controlling ptsGHI operon expression in Bacillus subtilis: RNA structure rather than sequence provides interaction specificity.  

Science.gov (United States)

The Gram-positive soil bacterium Bacillus subtilis transports glucose by the phosphotransferase system. The genes for this system are encoded in the ptsGHI operon. The expression of this operon is controlled at the level of transcript elongation by a protein-dependent riboswitch. In the absence of glucose a transcriptional terminator prevents elongation into the structural genes. In the presence of glucose, the GlcT protein is activated and binds and stabilizes an alternative RNA structure that overlaps the terminator and prevents termination. In this work, we have studied the structural and sequence requirements for the two mutually exclusive RNA structures, the terminator and the RNA antiterminator (the RAT sequence). In both cases, the structure seems to be more important than the actual sequence. The number of paired and unpaired bases in the RAT sequence is essential for recognition by the antiterminator protein GlcT. In contrast, mutations of individual bases are well tolerated as long as the general structure of the RAT is not impaired. The introduction of one additional base in the RAT changed its structure and resulted in complete loss of interaction with GlcT. In contrast, this mutant RAT was efficiently recognized by a different B.subtilis antitermination protein, LicT. PMID:15155854

Molecular Dynamics of Spin Crossover: the (P,T) phase diagram of [Fe(PM-BIA)2(NCS)2  

CERN Document Server

The spin crossover properties and the domains of existence of the different phases for the [Fe(PM-BIA)2(NCS)2] complex are obtained from combining DFT and classical molecular dynamics (MD). The potential energy surfaces expressed in the Morse form for Fe-N interactions are deduced from molecular DFT calculations and they allow producing Infra Red and Raman frequencies. These Fe-N potentials inserted in a classical force field lead from MD calculations to the relative energies of the high spin and low spin configurations of the orthorhombic structure. The MD investigations have also allowed assessing the experimental (P, T) phase diagram by showing the monoclinic polymorph in its two spin- states, and generating two triple points.

The occurrence of parasitic arthropods in two groups of European bison in the Bia?owieza primeval forest.  

Science.gov (United States)

Within 1992-2000, a total of 181 Bia?owieza Forest bison were examined from two winter herds. Twelf parasitic arthropod species were observed, a high infestation being typical of Demodex bisonianius, Chorioptes bovis, Ixodes ricinus, Dermacentor reticulatus, and Bisonicola sedecimdecembrii. The infestation in section 422 herd being higher for B. sedecimdecembrii, I. ricinus, D. reticulatus, Ch. bovis. D. bisonianus was slightly more prevalent in the section 391 herd, the intensity being, however, lower than that in the other herd. Among the remaining arthropods found in the Bialowieza Forest European bison, some Lipoptena cervi occurred in both herds, Demodex sp. and Sarcoptes scabiei were recorded only in the section 422 herd, Ixodes persulcatus was present only in the section 391 bison and those kept in the reservation, while D. bovis, Psoroptes ovis, and Melophagus ovinus were found in the reserve bison only. In the present study, the largest differences in the extent of infestation involved the hair-dwelling arthropods (B. sedecimdecembrii, I. rixinus). PMID:16886430

Enantioselective HPLC-UV method for determination of eslicarbazepine acetate (BIA 2-093) and its metabolites in human plasma.  

Science.gov (United States)

Eslicarbazepine acetate (BIA 2-093) is a novel central nervous system drug undergoing clinical phase III trials for epilepsy and phase II trials for bipolar disorder. A simple and reliable chiral reversed-phase HPLC-UV method was developed and validated for the simultaneous determination of eslicarbazepine acetate, oxcarbazepine, S-licarbazepine and R-licarbazepine in human plasma. The analytes and internal standard were extracted from plasma by a solid-phase extraction using Waters Oasis HLB cartridges. Chromatographic separation was achieved by isocratic elution with water-methanol (88:12, v/v), at a flow rate of 0.7 mL/min, on a LichroCART 250-4 ChiraDex (beta-cyclodextrin, 5 microm) column at 30 degrees C. All compounds were detected at 225 nm. Calibration curves were linear over the range 0.4-8 microg/mL for eslicarbazepine acetate and oxcarbazepine, and 0.4-80 microg/mL for each licarbazepine enantiomer. The overall intra- and interday precision and accuracy did not exceed 15%. Mean relative recoveries varied from 94.00 to 102.23% and the limit of quantification of the assay was 0.4 microg/mL for all compounds. This method seems to be a useful tool for clinical research and therapeutic drug monitoring of eslicarbazepine acetate and its metabolites S-licarbazepine, R-licarbazepine and oxcarbazepine.

Automated ground-based remote sensing measurements of greenhouse gases at the Bia?ystok site in comparison with collocated in situ measurements and model data  

Science.gov (United States)

The in situ boundary layer measurement site in Bia?ystok (Poland) has been upgraded with a fully automated observatory for total greenhouse gas column measurements. The automated Fourier Transform Spectrometer (FTS) complements the on-site in situ facilities and FTS solar absorption measurements have been recorded nearly continuously in clear and partially cloudy conditions since March 2009. Here, the FTS measurements are compared with the collocated tall tower data. Additionally, simulations of the Jena CO2 inversion model are evaluated with the Bia?ystok measurement facilities. The simulated seasonal CO2 cycle is slightly overestimated by a mean difference of 1.2 ppm ± 0.9 ppm (1?) in comparison with the FTS measurements. CO2 concentrations at the surface, measured at the tall tower (5 m, 90 m, 300 m), are slightly underestimated by -1.5 ppm, -1.6 ppm, and -0.7 ppm respectively during the day and by -9.1 ppm, -5.9 ppm, and -1.3 ppm during the night. The comparison of the simulated CO2 profiles with low aircraft profiles shows a slight overestimation of the lower troposphere (by up to 1 ppm) and an underestimation in near-surface heights until 800 m (by up to 2.5 ppm). In an appendix the automated FTS observatory, including the hardware components and the automation software, is described in its basics.

Participation and Protected Areas Governance: the Impact of Changing Influence of Local Authorities on the Conservation of the Bia?owie?a Primeval Forest, Poland  

Directory of Open Access Journals (Sweden)

Full Text Available According to the new conservation paradigm, protected areas should contribute to the socioeconomic development of host communities, and the latter ought to be included in participatory decision making concerning these areas. However, the understanding of participation is ambiguous and there are at least three major approaches, which may have different impacts on the governance of protected areas. We examine the case of the Bia?owie?a Primeval Forest in order to trace the effectiveness of changing modes of participation as well as to discuss the limitations and problems of public participation. Between 1918 and 2010, the role of local authorities changed from no influence to limited control over decision making regarding designation and enlargement of the Bia?owie?a National Park (BNP. As a result of these changes, attempts to enlarge the BNP over the whole forest were undermined. The evidence shows that power relations and instrumental reasons constituted the main drivers of the changing participation pattern with deliberative rationale lacking. As a result, the conservation goals were only partially achieved. We argue that when interests are clearly conflicting and win–win solutions are difficult to reach, room for constructive participation may be limited. In these circumstances, public involvement may turn into yet another venue for a power play between actors with vested interests, without bringing gains in legitimacy or new policy options. This is especially the case for countries with a relatively short democratic record where the government lacks the consistency and capacity to steer the process over the longer term.

A temporal-omic study of Propionibacterium freudenreichii CIRM-BIA1 adaptation strategies in conditions mimicking cheese ripening in the cold.  

Science.gov (United States)

Propionibacterium freudenreichii is used as a ripening culture in Swiss cheese manufacture. It grows when cheeses are ripened in a warm room (about 24°C). Cheeses with an acceptable eye formation level are transferred to a cold room (about 4°C), inducing a marked slowdown of propionic fermentation, but P. freudenreichii remains active in the cold. To investigate the P. freudenreichii strategies of adaptation and survival in the cold, we performed the first global gene expression profile for this species. The time-course transcriptomic response of P. freudenreichii CIRM-BIA1(T) strain was analyzed at five times of incubation, during growth at 30°C then for 9 days at 4°C, under conditions preventing nutrient starvation. Gene expression was also confirmed by RT-qPCR for 28 genes. In addition, proteomic experiments were carried out and the main metabolites were quantified. Microarray analysis revealed that 565 genes (25% of the protein-coding sequences of P. freudenreichii genome) were differentially expressed during transition from 30°C to 4°C (P1). At 4°C, a general slowing down was observed for genes implicated in the cell machinery. On the contrary, P. freudenreichii CIRM-BIA1(T) strain over-expressed genes involved in lactate, alanine and serine conversion to pyruvate, in gluconeogenesis, and in glycogen synthesis. Interestingly, the expression of different genes involved in the formation of important cheese flavor compounds, remained unchanged at 4°C. This could explain the contribution of P. freudenreichii to cheese ripening even in the cold. In conclusion, P. freudenreichii remains metabolically active at 4°C and induces pathways to maintain its long-term survival. PMID:22253706

The role of land-use visions for protection of forest landscapes: the Bia?owie?a Forest (Poland) / El rol de las visiones del uso del suelo en la protección de los paisajes forestales: el bosque de Bialowieza (Polonia)  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish Esta investigación estudió las relaciones entre el uso y protección del bosque Bia?owie?a, Polonia, durante el último siglo, particularmente en las décadas de la post-guerra. Debido a los extraordinarios valores naturales, esta área necesita una protección muy especial. Sin embargo, se han observado [...] diversos impactos negativos sobre el paisaje. Los cambios implicaron perforación y fragmentación del bosque causados por la continua tala de árboles, debido a la expansión urbana asociada al desarrollo turístico. El objetivo de esta investigación fue identificar los forzantes subyacentes de tendencia negativa y los obstáculos para el progreso de la conservación de la naturaleza en la zona. Comparación de puntos de vista, visiones de uso del suelo y manejo del bosque, evidenciaron importantes diferencias en actitudes, perspectivas y expectativas aplicadas al bosque de Bia?owie?a. El estudio reveló la importancia de la dimensión socio-cultural en el estado actual de evolución del paisaje. Esta influencia está relacionada con una presión constante sobre la explotación maderera, por lo menos parcialmente, desde una fuerte posición de la administración forestal en esta área y desde visiones específicas de uso de suelo que enfatizan los servicios económicos de los bosques. Cabe destacar, que acciones realizadas en todo el país y los numerosos esfuerzos para ampliar las áreas de protección no han tenido éxito hasta el momento. Se argumenta que la subestimación de los valores naturales expresada por las comunidades locales, además de las debilidades de la legislación ambiental del Estado, pueden traer serias amenazas para el paisaje analizado y afectar a todo el sistema de conservación de la naturaleza en Polonia. Abstract in english The work concentrated on relations between the issues of use and protection that developed in the Polish part of the Bia?owie?a Forest last century, particularly during the post-war decades. Owing to extraordinary natural values, the area deserves very careful protection, however, negative impacts o [...] n the landscape have been widely observed. The changes involving perforation and fragmentation of forest cover caused by continuous logging are accompanied by spatial disorder in built areas and their vicinities resulting from tourism development. The aim of the research was to identify the underlying forces of negative tendencies and simultaneously, obstacles to progress in nature conservation of the area. Comparison of views and visions of land-use and management of the Forest showed that great differences in attitudes, applied perspectives and expectations to the Bia?owie?a Forest exist. The study revealed the importance of a socio-cultural dimension for a current stage of landscape evolution. This influence is connected with a steady pressure on wood exploitation and results, at least partially, from a strong position of forest administration in this area and from specific land-use visions emphasizing economic services of the forest. Noteworthy, actions undertaken across the country and numerous efforts to extend protection of the area have not succeeded so far. It is argued that underestimation of natural values expressed by local communities in addition to weaknesses of the state’s environmental law may bring serious hazards to the analysed landscape and affect the whole system of nature conservation in Poland.

Generalized GHY term for f(R) Gravity  

CERN Document Server

A generalization to the Gibbons-Hawking-York boundary term for metric $f(R)$ gravity theories is introduced. A redefinition of the Gibbons-Hawking-York term is proposed. The proposed new definition is used to derive a consistent set of field equations and is extended to metric $f(R)$ gravity theories. The surface terms in the action are gathered into a total variation of some quantity. A total divergence term is added to the action to cancel these terms. Finally, the new definition is proven to demand no restrictions on the value of ${\\delta g}_{ab}$ or ${\\partial}_{c}{\\delta g}_{ab}$ on the boundary.

The experimental use of a statistical algorithm and GIS for detecting the spatial reach of the impact of a dam reservoir on the development of a river channel. The case of the Dunajec and the Bia?ka rivers, the Polish Carpathians  

Science.gov (United States)

The determination of the spatial reach of the impact of dam reservoirs on the development of river channels is a key issue in fluvial geomorphology, river engineering and ecology. Until now the impact of dam reservoirs on river channels above these structures has been poorly explored. In particular, there has been no answer to the question: What is the spatial reach of changes in a river channel above a dam reservoir? and Is the reach of these changes broader than the reach of the backwater itself? To answer these questions, a statistical algorithm searching for channel sections homogeneous with respect to a given parameter and the threshold values between them was experimentally used in this paper. The study was conducted on the example of the channels of two rivers (the Dunajec and the Bia?ka) flowing into the Czorszty?ski Reservoir (CR) (Polish Carpathians) built in 1997. Information on the width, the average annual migration rate of a channel and the erosion and lateral accumulation in the river channel was used as input parameters. This information was collected using GIS software from 5 sets of orthophoto maps and georectified aerial photographs taken before (1977, 1982, 1994) and after (2003, 2009) the construction of the CR in the channel sections of the Dunajec and the Bia?ka, of 4700 m and 1900 m in length above the CR. The spatial-temporal pattern of changes in the structure and dynamics of the channel identified by the statistical algorithm shows that the changes interpreted as the impact of the reservoir (change in the channel width, lateral erosion, lateral acumulation and migration rate) had a reach in the river channel of about 1000 m broader than the reach of the reservoir's backwater. Sections of changed structure (width) coincided spatially with sections of changed dynamics (migration rate). The paper shows that statistical algorithms may be useful in the detection of sections of channels transformed by the impact of hydrotechnical developments.

Carbamazepine (CBZ) has been extensively used in the treatment of epilepsy, as well as in the treatment of neuropathic pain and affective disorders. However, the mechanisms of action of this drug are not completely elucidated and are still a matter of debate. Since CBZ is not very effective in some epileptic patients and may cause several adverse effects, several antiepileptic drugs have been developed by structural variation of CBZ, such as oxcarbazepine (OXC), which is used in the treatment...

Full Text Available Introduction. Acute myeloid leukaemia is a malignant neoplastic diseaseof white blood cells. About 80% of acute leukaemias in adult arediagnosed as myeloid leukaemias. The presence of transformed cellclones in bone marrow and blood, which originate from very earlystages of myelopoiesis, is characteristic. Beside systemic symptoms(anaemia, thrombocytopenia there are infiltrations in other organs,including skin. Skin lesions are most frequently non-specific (pruritus,skin spots, erythema multiforme, bullous pemphigoid but can be alsospecific (skin tumours. Cases of diffuse xanthomatoses and myeloidsarcoma have also been found in patients with acute myeloidleukaemia. Skin lesions are present more often in lymphocytic thanmyeloid leukaemias. They may precede the disease or its relapse, occurconcomitantly or after systemic symptoms, and sometimes may be ofprognostic value.Objective. To present the case of a patient in whom skin lesions werethe cause of detailed examinations, which revealed acute myeloidleukaemia.Case report. We present a case of a 61-year old patient with purplebrownnodular lesions 1-3 cm in diameter on the face, scalp skin, trunk,limbs and the oral cavity’s mucous membranes with coexistent intensepruritus and generalized lymphadenopathy. The first skin lesionsoccurred three months earlier. During hospitalization in the Departmentof Dermatology the renewal of blasts in the circulatory blood wasobserved and skin biopsy revealed a large amount of mononuclearcells. The patient was directed to the haematological ward, where thediagnosis of acute myeloid leukaemia was established.Conclusions. Our case indicates that the presence of skin lesions andthorough diagnostic procedures may contribute to the diagnosis ofmalignant neoplastic diseases of white blood cells.

International Nuclear Information System (INIS)

Coupling both thermography and bio-Impedance, some biophysical acupuncture mechanisms are statically studied on a small population of 18 subjects. Results show that a possible way of understanding acupuncture, in an electrical way, should be to consider ionic flux redistribution between vascular and extra cell compartments. This is a two steps mechanism. The first one is starting with needles insertion and the second one is lasting with more intensity after removing them from skin.

[Porencephalia vera in autopsy specimens from the Department of Pathological Anatomy, Medical Academy, in Bia?ystok 1976-1985].  

Science.gov (United States)

Morphological and statistical analysis of true porencephaly based on 2793 autopsies of children aged up to 18 years showed 12 cases of porencephaly, accounting for 0.43% of the autopsy material, and 5.2% of all anomalies of the central nervous system in this age group. The greatest number of porencephaly cases (6) was in the age group 3-18 years. The anomaly was twice as frequent in boys (8 cases) than girls (4 cases). Nine cases of porencephaly showed coexistence of other developmental anomalies (75%) mainly with those of central nervous system, especially microecephaly, congenital hydrocephalus, which could indicate a genetic determination of the anomaly. The most frequent associated neurological singn in porencephaly was psychomotor underdevelopment. PMID:3226475

Enhancing the Efficiency of SnS Solar Cells bia Band-Offset Engineering with a Zinc Oxysulfide Buffer Layer  

Digital Repository Infrastructure Vision for European Research (DRIVER)

SnS is a promising earth-abundant material for photovoltaic applications. Heterojuction solar cells were made by vapor deposition of p-type tin(II) sulfide, SnS, and n-type zinc oxysulfide, Zn(O,S), using a device structure of soda-lime glass/Mo/SnS/Zn(O,S)/ZnO/ITO. A record efficiency was achieved for SnS-based thin-film solar cells by varying the oxygen-to-sulfur ratio in Zn(O,S). Increasing the sulfur content in Zn(O,S) raises the conduction band offset between Zn(O,S) and SnS to an opti...

Science.gov (United States)

In patients with allergic changes hospitalized in the years 1984-1988 in the Department a careful history was obtained for detection of correlations between the appearance of skin lesions and contact with plants. In patients with a positive history patch tests were done with a panel of routine allergens and leaves and/or flowers of certain plants. Positive tests with various plants were obtained in 14 cases. In 6 patients reporting contact with primrose positive tests were obtained with flowers and leaves of this plant, four of five tobacco planters tested who had eczematous lesions of the hands, aave also positive results of the test with tobacco leaves, and in three children reporting contact with butter-cup changes were observed resembling dermatitis pratensis bullosa. In one case allergy to parsnip was demonstrated. It is stressed that plants may give rise to contact dermatitis as well as to allergic-toxic changes. PMID:2148400

Variability of the soil seed banks in the natural deciduous forest in the Bia?owie?a National Park  

Directory of Open Access Journals (Sweden)

Full Text Available Using the germination method, the species diversity, density of the soil seed bank and its relation to cover vegetation in a natural deciduous forest with primary and secondary tree stand were compared. It was found that the mean density and species composition of the soil seed bank in the forest with secondary tree stand that has spontaneously been overgrown over the last 90 years after clear-cutting does not differ from the soil seed bank derived from primeval forest (3167M-2 vs. 3827m-2. In both stands there were 46 species altogether and 36 were common and seed banks were dominated by herbs. The most abundant in this group were: Urtica dioica, Chrysosplenium alternifolium, Geranium robertianum, Oxalis acetosella. In both cases it was found that the species structure of the herb layer was similar to that of the seed bank in about 70%. The seed banks of species absent from the herb layer or present there only sporadically were much more abundant. The seedlings of these species constituted more than one third of all seedlings that emerged in the samples from the secondary tree stand and only 5% those from the primary one. The analysis of seed bank in heavily rooted places under primary and secondary tree stands showed that in places with a totally distroyed herb layer the density of the soil seed bank in primeval forest was three times lower than in places with fully developed herb layer structure (102.60±22.61 vs. 307.0±206.5 per sample. This difference under secondary tree stand turned out to be much lower (415.8±137.8 vs. 358.2±126.0 per sample.

Spatial Estimation of Sub-Hour Global Horizontal Irradiance Based on Official Observations and Remote Sensors  

Directory of Open Access Journals (Sweden)

Full Text Available This study was motivated by the need to improve densification of Global Horizontal Irradiance (GHI observations, increasing the number of surface weather stations that observe it, using sensors with a sub-hour periodicity and examining the methods of spatial GHI estimation (by interpolation with that periodicity in other locations. The aim of the present research project is to analyze the goodness of 15-minute GHI spatial estimations for five methods in the territory of Spain (three geo-statistical interpolation methods, one deterministic method and the HelioSat2 method, which is based on satellite images. The research concludes that, when the work area has adequate station density, the best method for estimating GHI every 15 min is Regression Kriging interpolation using GHI estimated from satellite images as one of the input variables. On the contrary, when station density is low, the best method is estimating GHI directly from satellite images. A comparison between the GHI observed by volunteer stations and the estimation model applied concludes that 67% of the volunteer stations analyzed present values within the margin of error (average of ±2 standard deviations.

Comparisons of body-composition prediction accuracy: a study of 2 bioelectric impedance consumer devices in healthy Chinese persons using DXA and MRI as criteria methods.  

Science.gov (United States)

We compared the accuracy of body-composition estimation for 2 commercial single-frequency bioelectric impedance analysis (BIA) devices in 200 healthy Chinese adults using magnetic resonance imaging (MRI) and dual-energy X-ray absorptiometry (DXA) as criterion methods. We evaluated the fat mass percentage (%FM), skeletal muscle mass percentage (%SM), or total-body bone-free lean mass percentage (%TBBLM), and level of visceral fat mass (VF(level)) using the Omron HBF-359 (SF-BIA8) and Tanita BC-532 (SF-BIA4) BIA devices, MRI, and DXA. Both devices showed a similarly high correlation with DXA for %FM prediction (r=0.89 for SF-BIA8 and 0.90 for SF-BIA4) and with MRI and DXA for %SM and %TBBLM prediction (r=0.85 for SF-BIA8 and 0.89 for SF-BIA4). There were small but significant biases in all body-composition parameter evaluations except for %SM assessed by the SF-BIA8. Both the SF-BIA8 and SF-BIA4 provided small, insignificant mean biases but wide limits of agreement with MRI for VF(level) assessments. Both BIA devices can relatively accurately predict %FM and %SM in healthy Chinese adults. The SF-BIA8 is suitable for individual prediction of %SM, whereas the SF-BIA8 is required to eliminate systematic errors in this population by improving population-specific prediction equations from height, weight, and age to increase estimation accuracy.

[STAT5B deficiency: a new growth hormone insensitivity syndrome associated to immunological dysfunction].  

Science.gov (United States)

A new presentation of growth hormone insensitivity (GHI) caused by homozygous mutations in STAT5B (signal transducer and activator of transcription 5B) gene has been characterized in the last years. Its particularity is the association with severe immune dysfunction, especially with lymphocytic interstitial pneumonitis. This may mislead physicians into considering short stature as secondary to chronic immunological disease and consequently into underdiagnosing this form of GHI. The objective of this review is to propagate current knowledge about this rare pathology, facilitating the diagnosis of patients with GHI due to STAT5B mutations in endocrinology and other specialties clinics.

No apparent progress in bioelectrical impedance accuracy: validation against metabolic risk and DXA.  

Science.gov (United States)

Bioelectrical impedance (BIA) is quick, easy, and safe when quantifying fat and lean tissue. New BIA models (Tanita BC-418 MA, abbreviated BIA(8)) can perform segmental body composition analysis, e.g., estimate %trunkal fatness (%TF). It is not known, however, whether new BIA models can detect metabolic risk factors (MRFs) better than older models (Tanita TBF-300, abbreviated BIA(4)). We therefore tested the correlation between MRF and percentage whole-body fat (%BF) from BIA(4) and BIA(8) and compared these with the correlation between MRF and dual-energy X-ray absorptiometry (DXA, used as gold standard), BMI and waist circumference (WC). The sample consisted of 136 abdominally obese (WC >or= 88 cm), middle-aged (30-60 years) women. MRF included fasting blood glucose and insulin; high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides; high sensitive C-reactive protein, plasminogen activator inhibitor-1 (PAI-1), and fibrinogen; and alanine transaminase (ALT) liver enzyme. We found that similar to DXA, but in contrast to BMI, neither %BF BIA(4) nor %BF BIA(8) correlated with blood lipids or ALT. In the segmental analysis of %TF, BIA(8) only correlated with inflammatory markers, but not insulin, blood lipids, or ALT liver enzyme (in contrast to WC and %TF DXA). %TF DXA was associated with homeostatic model assessment insulin resistance (HOMA-IR) independently of WC (P = 0.03), whereas %TF BIA(8) was not (P = 0.53). Receiver-operating characteristic (ROC) curves confirmed that %TF BIA(8) did not differ from chance in the detection of insulin resistance (P = 0.26). BIA estimates of fatness were, at best, weakly correlated with obesity-related risk factors in abdominally obese women, even the new eight-electrode model. Our data support the continued use of WC and BMI. PMID:18997678

IgA antibodies against fusion protein containing modified nonapeptide of gliadin in dermatitis herpetiformis. Przeciwcia?a IgA przeciwko bia?ku fuzyjnemu zawieraj?cemu zmodyfikowany nonapeptyd gliadyny w opryszczkowatym zapaleniu skóry.  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Dermatitis herpetiformis (DH is a chronic, intensely itchy, blistering skin manifestation of gluten sensitive enteropathy, commonly known as celiac disease. Epidermal transglutaminase and closely related tissue transglutaminase are considered to be autoantigens in DH. Direct immunofluorescence test (DIF of nonlesional skin remains definitive laboratory test for diagnosing this disease. Aim of the study: The aim of this work was to assess the level of serum IgA antibodies to fusion modified protein containing nonapeptide of gliadin in patients with DH and evaluate usefulness of ELISA measuring those antibodies in dealing with DH patients. Material and methods: Sera from 26 patients with DH were examined. All patients had typical IgA deposits detected with DIF. IgA antibodies against fusion protein containing modified nonapeptide of gliadin were detected using ELISA. Epicutaneous patch tests were also performed in 9 of 26 DH patients. Results: IgA antibodies against fusion protein containing nonapeptide of gliadin were found in 85% of DH sera. At blood taking 92% of patients had cutaneous lesions, 32% had intestinal symptoms, 9% had been on a gluten-free diet, and 14% were treated with dapsone. The male to female ratio was 1.36:1. None of tested patients was allergic to nickel. Conclusions: Our data suggests that testing for IgA antibodies to fusion protein containing modified nonapeptide of gliadin is a useful adjunct in diagnosing DH.

Voltammetric characterisation of the aerobic energy dissipating nitrate reductase of Paracoccus pantotrophus: exploring the activity of a redox balancing enzyme as a function of electrochemical potential  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Abstract Paracoccus pantotrophus expresses two nitrate reductases associated with respiratory electron transport, NapABC and NarGHI. Both enzymes derive electrons from ubiquinol to reduce nitrate to nitrite. However, while NarGHI harnesses the energy of the quinol/nitrate couple to generate a transmembrane proton gradient, NapABC dissipates the energy associated with these reducing equivalents. Here we explore the nitrate reductase activity of purified NapAB as a function of electr...

Validation of bioelectrical-impedance analysis as a measurement of change in body composition in obesity  

International Nuclear Information System (INIS)

The bioelectrical-impedance-analysis (BIA) method accurately measures body composition in weight-stable subjects. This study validates the use of BIA to measure change in body composition. Twelve obese females underwent weight loss at a mean rate of 1.16 kg/wk. Body composition was measured by deuterium oxide dilution (D2O), BIA, and skinfold anthropometry (SFA) at baseline and at 5% decrements in weight. Highly significant correlations were obtained between D2O and BIA (r = 0.971) and between D2O and SFA (r = 0.932). Overall, BIA predicted change in fat-free mass with greater accuracy (to 0.4 kg) and precision (+/- 1.28 kg) than did anthropometry (to 0.8 kg and +/- 2.58 kg, respectively). We conclude that BIA is a useful clinical method for measuring change in body composition

Full Text Available Objective: The application of body mass index (BMI for obesity classification in all population studies has been questioned by the scientific community. It has been found that the bioelectrical impedance analysis (BIA is an accurate method for screening obesity. This study was conducted to evaluate the accuracies of BMI, skinfold thickness (SFT, leptin and BIA measurements in obesity classification and to find correlations between BIA and the other indicators for obesity. Materials and Methods: This case-control study included 178 children of whom 90 were in the obese group and 88 in the control group. The study measured BMI, SFT, leptin level and BIA-mediated body fat percentage (BIA BFP in each child. Results: The BMIs, leptin levels, SFTs and BIA BFPs of children in the obese group were found to be higher than those in the control group (p<0.001. The measurement of BIA BFP strongly correlated with BMI, SFT and waist circumference, whereas BIA BFP measurement showed weak-moderate correlation with leptin level. Conclusion: Bioelectrical impedance analysis was found to be an accurate measure of BFP in obesity. In addition, BIA may prevent the incorrect diagnosis of obesity as determined by BMI alone, especially in boys during the pubertal period.

Estimation of confidence intervals of global horizontal irradiance obtained from a weather prediction model  

Science.gov (United States)

Many photovoltaic (PV) systems have been installed in Japan after the introduction of the Feed-in-Tariff. For an energy management of electric power systems included many PV systems, the forecast of the PV power production are useful technology. Recently numerical weather predictions have been applied to forecast the PV power production while the forecasted values invariably have forecast errors for each modeling system. So, we must use the forecast data considering its error. In this study, we attempted to estimate confidence intervals for hourly forecasts of global horizontal irradiance (GHI) values obtained from a mesoscale model (MSM) de-veloped by the Japan Meteorological Agency. In the recent study, we found that the forecasted values of the GHI of the MSM have two systematical forecast errors; the first is that forecast values of the GHI are depended on the clearness indices, which are defined as the GHI values divided by the extraterrestrial solar irradiance. The second is that forecast errors have the seasonal variations; the overestimation of the GHI forecasts is found in winter while the underestimation of those is found in summer. The information of the errors of the hourly GHI forecasts, that is, confidence intervals of the forecasts, is of great significance for planning the energy management included a lot of PV systems by an electric company. On the PV systems, confidence intervals of the GHI forecasts are required for a pinpoint area or for a relatively large area control-ling the power system. For the relatively large area, a spatial-smoothing method of the GHI values is performed for both the observations and forecasts. The spatial-smoothing method caused the decline of confidence intervals of the hourly GHI forecasts on an extreme event of the GHI forecast (a case of large forecast error) over the relatively large area of the Tokyo electric company (approximately 68 % than for a pinpoint forecast). For more credible estimation of the confidence intervals, it is required to consider the location of the installed PV systems or its capacity over the region.

A Comparison Between Heliosat-2 and Artificial Neural Network Methods for Global Horizontal Irradiance Retrievals over Desert Environments  

Science.gov (United States)

Global horizontal irradiance (GHI) retrievals at the surface of any given location could be used for preliminary solar resource assessments. More accurately, the direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI) are also required to estimate the global tilt irradiance, mainly used for fixed flat plate collectors. Two different satellite-based models for solar irradiance retrievals have been applied over the desert environment of the United Arab Emirates (UAE). Both models employ channels of the SEVIRI instrument, onboard the geostationary satellite Meteosat Second Generation, as their main inputs. The satellite images used in this study have a temporal resolution of 15-min and a spatial resolution of 3-km. The objective of this study is to compare between the GHI retrieved using the Heliosat-2 method and an artificial neural network (ANN) ensemble method over the UAE. The high-resolution visible channel of SEVIRI is used in the Heliosat-2 method to derive the cloud index. The cloud index is then used to compute the cloud transmission, while the cloud-free GHI is computed from the Linke turbidity factor. The product of the cloud transmission and the cloud-free GHI denotes the estimated GHI. A constant underestimation is observed in the estimated GHI over the dataset available in the UAE. Therefore, the cloud-free DHI equation in the model was recalibrated to fix the bias. After recalibration, results over the UAE show a root mean square error (RMSE) value of 10.1% and a mean bias error (MBE) of -0.5%. As for the ANN approach, six thermal channels of SEVIRI were used to estimate the DHI and the total optical depth of the atmosphere (?). An ensemble approach is employed to obtain a better generalizability of the results, as opposed to using one single weak network. The DNI is then computed from the estimated ? using the Beer-Bouguer-Lambert law. The GHI is computed from the DNI and DHI estimates. The RMSE for the estimated GHI obtained over an independent dataset over the UAE is 7.2% and the MBE is +1.9%. The results obtained by the two methods have shown that both the recalibrated Heliosat-2 and the ANN ensemble methods estimate the GHI at a 15-min resolution with high accuracy. The advantage of the ANN ensemble approach is that it derives the GHI from accurate DNI and DHI estimates. The DNI and DHI estimates are valuable when computing the global tilt irradiance. Also, accurate DNI estimates are beneficial for preliminary site selection for concentrating solar powered plants.

Practical issues in handling data input and uncertainty in a budget impact analysis.  

Science.gov (United States)

The objective of this paper was to address the importance of dealing systematically and comprehensively with uncertainty in a budget impact analysis (BIA) in more detail. The handling of uncertainty in health economics was used as a point of reference for addressing the uncertainty in a BIA. This overview shows that standard methods of sensitivity analysis, which are used for standard data set in a health economic model (clinical probabilities, treatment patterns, resource utilisation and prices/tariffs), cannot always be used for the input data for the BIA model beyond the health economic data set for various reasons. Whereas in a health economic model, only limited data may come from a Delphi panel, a BIA model often relies on a majority of data taken from a Delphi panel. In addition, the dataset in a BIA model also includes forecasts (e.g. annual growth, uptakes curves, substitution effects, changes in prescription restrictions and guidelines, future distribution of the available treatment modalities, off-label use). As a consequence, the use of standard sensitivity analyses for BIA data set might be limited because of the lack of appropriate distributions as data sources are limited, or because of the need for forecasting. Therefore, scenario analyses might be more appropriate to capture the uncertainty in the BIA data set in the overall BIA model. PMID:20364289

Bioelectrical impedance analysis. What does it measure?  

Science.gov (United States)

Bioelectrical impedance analysis (BIA) has been proposed for measuring fat-free mass, total body water, percent fat, body cell mass, intracellular water, and extracellular water: a veritable laboratory in a box. Although it is unlikely that BIA is quite this versatile, correlations have been demonstrated between BIA and all of these body compartments. At the same time, it is known that all of the compartments are correlated among themselves. Because of this, it is difficult to determine whether BIA is specific for any or all of these compartments. To investigate this question, we induced acute changes in total body water and its compartments over a 3-h period. Using this approach, we demonstrated that multifrequency BIA, using the Cole-Cole model to calculate the zero frequency and infinite frequency resistance, measures extracellular and intracellular water.

Full Text Available SciELO Brazil | Language: English Abstract in portuguese INTRODUÇÃO: Até o momento, aproximadamente 60 diferentes mutações envolvendo o gene do receptor do GH (GHR) foram descritas em pacientes com a síndrome de insensibilidade ao GH (GHI). Neste artigo, descrevemos uma nova mutação nonsense do GHR. MÉTODOS: O paciente foi avaliado aos 6 anos de idade par [...] a baixa estatura associada ao fenótipo clínico da GHI. Níveis de GH, IGF-1 e GHBP foram determinados. Os produtos de PCR dos éxons 2-10 foram seqüenciados. RESULTADOS: O paciente apresentou níveis elevados de GH (26 µg/L), baixos de IGF-1 (22.5 ng/ml) e indetectáveis de GHBP. O seqüenciamento do éxon 5 do GHR revelou uma duplicação da adenina no nucleotídeo 338 da sequência de codificação do GHR (c.338dupA) em homozigose. CONCLUSÃO: Descrevemos uma nova mutação que causa um GHR truncado e uma perda da função do receptor devido à perda de aminoácidos compreendendo as regiões transmembrana e intracelular do receptor, levando a GHI. Abstract in english BACKGROUND: To date, about sixty different mutations within GH receptor (GHR) gene have been described in patients with GH insensitivity syndrome (GHI). In this report, we described a novel nonsense mutation of GHR. METHODS: The patient was evaluated at the age of 6 yr, for short stature associated [...] to clinical phenotype of GHI. GH, IGF-1, and GHBP levels were determined. The PCR products from exons 2-10 were sequenced. RESULTS: The patient had high GH (26 µg/L), low IGF-1 (22.5 ng/ml) and undetectable GHBP levels. The sequencing of GHR exon 5 disclosed adenine duplication at nucleotide 338 of GHR coding sequence (c.338dupA) in homozygous state. CONCLUSION: We described a novel mutation that causes a truncated GHR and a loss of receptor function due to the lack of amino acids comprising the transmembrane and intracellular regions of GHR protein, leading to GHI.

The use of bioelectrical impedance analysis for body composition in epidemiological studies  

DEFF Research Database (Denmark)

BACKGROUND/OBJECTIVES: Bioelectrical impedance analysis (BIA) is a relatively simple, inexpensive and non-invasive technique to measure body composition and is therefore suitable in field studies and larger surveys. SUBJECTS/METHODS: We performed an overview of BIA-derived body fat percentages (BF%) from 55 published studies of healthy populations aged 6-80 years. In addition, the relationship between body mass index (BMI) and body composition is documented in the context of BIA as a good alternative to closely differentiate which composition of the body better relates to the risk of cardiovascular diseases (CVDs)and all-cause mortality. RESULTS AND CONCLUSIONS: BIA-estimated percentage of BF varies greatly with population and age. BIA-estimated BF% is directly and closely related to various health outcomes such as CVDs, which is in contrast to BMI where both high and low BMIs are associated with increased risk of developing chronic diseases. Studies, among others using BIA, suggest that low BMI may reflectlow muscle and high BMI fat mass (FM). BIA-derived lean and FM is directly associated with morbidity and mortality. To the contrary, BMI is rather of limited use for measuring BF% in epidemiological studies.

Multiple frequency bioimpedance is an adequate tool to assess total and regional fat mass in HIV-positive patients but not to diagnose HIV-associated lipoatrophy: a pilot study  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: HIV-associated lipodystrophy syndrome causes systemic metabolic alterations and psychological distress that worsen the quality of life of these patients. An early detection should be considered to efficiently treat it. Objective criteria or reference indices are needed for an early diagnosis. Bioelectrical Impedance Analysis (BIA is an operator-independent, repeatable and non-invasive method of body composition evaluation that is less expensive than dual-energy X-ray absorptiometry (DXA and/or CT scans. The aims of this pilot study were to validate the data obtained by BIA to measure fat mass in HIV-positive patients with/without lipoatrophy and to determine if BIA correctly diagnoses lipoatrophy in HIV-positive patients. Methods: Thirty-nine participants were included in this preliminary study. Fourteen were HIV-negative (eight men whereas 25 were HIV-positive patients (17 men. Eleven of the HIV-positive patients were classified as lipoatrophic according to subjective evaluation by the physicians. Total and regional body composition was measured in basal conditions by DXA and by BIA. To obtain abdominal CT scan fat values, transverse slices with 6-mm thickness were acquired at the L4-L5 intervertebral space. Results: BIA measurements of total and regional body fat were significantly correlated with those obtained by DXA (p < 0.05 to <0.01 in HIV-positive patients. However, agreement between methods was poor as not very high ICC (intraclass correlation coefficient values were observed. BIA and DXA showed higher ICC values in lipoatrophic patients. The visceral index obtained by BIA was correlated with total and visceral fat in L4 measured by CT scan (r = 0.607 and r = 0.617, respectively, p < 0.01 in HIV-positive patients. The Fat Mass Ratio (FMR calculated by BIA did not correlate or agree with DXA values. Conclusions: Multi-frequency BIA could be an effective method to evaluate the evolution of total and regional fat composition in HIV-positive patients with/without lipoatrophy. The correlations between BIA and DXA improved in lipoatrophic patients and in men, suggesting that its efficacy depends on fat mass, gender and probably other factors. The visceral index obtained by BIA seems to be a reliable indicator of abdominal obesity. However, BIA did not fulfil the need for easy quantitative diagnostic tools for lipoatrophy, and it did not provide sufficient diagnostic cut-off values for this syndrome.

Full Text Available Introduction: Basal cell carcinoma (BCC is the most common type of skin cancer and its incidence appears to be increasing. Objective: Reasons to undertake the study of desmoglein 3 protein (DSG3 expression in BCC were twofold: (i DSG3-linked pemphigus vulgaris (PV, a life-threatening autoimmune blistering dermatosis, can coexist with malignancy, (ii hair follicles, which physiologically express DSG3, apparently are involved in both PV pathogenesis (mature follicular cells and BCC pathogenesis (stem cells of the bulge region of hair follicle. Material and methods: DSG3 expression was evaluated in BCC-affected areas in patients with BCC (22 specimens; BCC tumor, in non-BCC-affected epidermis in patients with BCC (21 specimens; control 1 and in more benign tumors than BCC (12 seborrheic keratosis specimens and 10 keratosis senilis specimens; control 2. The immunohistochemical staining on frozen sections was performed using monoclonal murine anti-DSG3 antibody. The digital microscopic image analysis with quantitative morphometric software was then used to measure the intensity of positive immunostaining signals of the DSG3 in the area of interest (tumor-affected, tumor-free. Results: There was significantly lower expression of DSG3 in BCC tumor compared to both control 1 and control 2. There was no significant difference of DSG3 expression in control 1 and control 2. Conclusions: Thus, it seems that DSG3 might have some role in BCC pathogenesis as its decreased expression in BCC-affected epidermis might reflect just locally invasive behavior of that tumor. Apparently, factors independent from DSG3 are capable to keep BCC cells in clusters, but are incapable to do the same as far as keratinocytes in PV are concerned.

Science.gov (United States)

This paper presents the results of studies on gas sorption performed by means of the gravimetric method. The tests were performed on two coal samples of different metamorphism degrees, came from two regions of Upper Silesian Coal Basin, Poland. The changes in sorption capacity of coals were measured in the pressure range from 0.1 MPa to 17 MPa and in temperatures ranging from 291K to 333K. Coal of a lower coalification degree was a better methane sorbent. Changes in sorption capacity of tested coals were linearly dependent on the temperature. The increase in temperature of 10K reduces the Langmuir sorption of about 0.7-0.8 [cm3/g]. Such increase of temperature causes a nonlinear increase of the Langmuir pressure (b-1). These results showed that the rise of rock temperature, caused by geothermal gradient, can induce a significant increase of equilibrium pressure of methane in coal seam. An increase of coal seam temperature may cause an increase of gas and coal outburst risk in a coal mine.

Earthquake risk mitigation projects in central asia and india  

Science.gov (United States)

In the fall of 2002, GeoHazards International (GHI), a California-based nonprofit organization, launched two 3-year projects, each funded by the U.S. Agency for International Development, to improve the earthquake risk management of 23 cities in Central Asia and India. The objectives of these projects are to: * Assess the earthquake risk of each city, * Identify the most effective risk mitigation options for each city, * Raise awareness of that risk and those mitigation options, and * Initiate mitigation activities in some of these cities. A critical characteristic of these projects is that leaders of each local community will be deeply involved in realizing all four objectives. GHI will work with, in addition to local authorities, national government, academic and non-governmental organizations. In India, GHI’s partners are the Disaster Management Planning Hyogo Office, United Nations Centre for Regional Development (UNCRD) of Kobe, Japan, and the Sustainable Environment and Ecological Development Society (SEEDS), of Delhi, India. In India, we will work in 20 cities that were chosen, in a February 1, 2002 workshop (sponsored by Munich Reinsurance Company) in Delhi; the cities were selected by Indian earthquake professionals on the basis of the cities’ population, hazard, and economic, cultural and political significance. In Central Asia, we will focus on Tashkent, Uzbekistan; Dushanbe, Tadzhikistan; and Almaty, Kazakstan. GHI and its partners are looking for other organizations that would like to collaborate on these projects.

Validating an operational physical method to compute surface radiation from geostationary satellites  

Science.gov (United States)

Models to compute global horizontal irradiance (GHI) and direct normal irradiance (DNI) have been in development over the last three decades. These models can be classified as empirical or physical based on the approach. Empirical models relate ground-based observations with satellite measurements and use these relations to compute surface radiation. Physical models consider the physics behind the radiation received at the satellite and create retrievals to estimate surface radiation. While empirical methods have been traditionally used for computing surface radiation for the solar energy industry, the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is a physical model that computes DNI and GHI using the visible and infrared channel measurements from a weather satellite. GSIP uses a two-stage scheme that first retrieves cloud properties and uses those properties in a radiative transfer model to calculate GHI and DNI. Developed for polar orbiting satellites, GSIP has been adapted to NOAA's Geostationary Operation Environmental Satellite series and can run operationally at high spatial resolutions. This method holds the possibility of creating high quality datasets of GHI and DNI for use by the solar energy industry. We present an outline of the methodology and results from running the model as well as a validation study using ground-based instruments.

The Estimation of the Fat Free Mass Index in Athletes.  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: The purpose of this investigation was to compare a practical measurement of fat free mass index (FFMI from bioelectrical impedance analysis (BIA to the dual energy X-ray absorptiometry (DEXA value in collegiate athletes.Methods: Thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. Subjects visited the laboratory once and had their measurements taken in the following order: weight, height, DEXA, and Omron HBF-500.Results: The BIA device investigated was not a valid estimate of FFMI when compared to the DEXA. The TE was 0.93 kg/ m2 for males and 0.78 kg/ m2 for females. There were also significant mean differences between the BIA prediction and the DEXA value for males (BIA=20.6 kg/m2 vs. DEXA=21.1 kg/m2, P=0.007 and females (BIA=16.2 kg/m2 vs. DEXA=17.5 kg/m2, P=0.001.Conclusions: The BIA device investigated in this study did not provide a valid estimate of FFMI in male and female collegiate athletes. Although there was a general tendency for the BIA to underestimate FFMI compared to DEXA, 98% of the estimates were within plus or minus 2 kg/ m2. Therefore, while slightly biased, BIA may provide a reasonable (± 2 kg/ m2 estimate of nutritional status for practitioners who are unable able to afford more expensive equipment.

Genetic Evidence for the Reduction of Brassinosteroid Levels by a BAHD Acyltransferase-Like Protein in Arabidopsis1[W][OA  

Science.gov (United States)

Brassinosteroids (BRs) are a group of steroidal hormones involved in plant development. Although the BR biosynthesis pathways are well characterized, the BR inactivation process, which contributes to BR homeostasis, is less understood. Here, we show that a member of the BAHD (for benzylalcohol O-acetyltransferase, anthocyanin O-hydroxycinnamoyltransferase, anthranilate N-hydroxycinnamoyl/benzoyltransferase, and deacetylvindoline 4-O-acetyltransferase) acyltransferase family may play a role in BR homeostasis in Arabidopsis (Arabidopsis thaliana). We isolated two gain-of-function mutants, brassinosteroid inactivator1-1Dominant (bia1-1D) and bia1-2D, in which a novel BAHD acyltransferase-like protein was transcriptionally activated. Both mutants exhibited dwarfism, reduced male fertility, and deetiolation in darkness, which are typical phenotypes of plants defective in BR biosynthesis. Exogenous BR treatment rescued the phenotypes of the bia1-1D mutant. Endogenous levels of BRs were reduced in the bia1-1D mutant, demonstrating that BIA1 regulates endogenous BR levels. When grown in darkness, the bia1 loss-of-function mutant showed a longer hypocotyl phenotype and was more responsive to exogenous BR treatment than the wild-type plant. BIA1 expression was predominantly observed in the root, where low levels of BRs were detected. These results indicate that the BAHD acyltransferase family member encoded by BIA1 plays a role in controlling BR levels, particularly in the root and hypocotyl in darkness. Taken together, our study provides new insights into a mechanism that maintains BR homeostasis in Arabidopsis, likely via acyl conjugation of BRs. PMID:22544867

Evaluation of two foot-to-foot bioelectrical impedance analysers to assess body composition in overweight and obese adolescents.  

Science.gov (United States)

The objective of the present study was to determine the accuracy of two foot-to-foot (FF) bioelectrical impedance analysers (BIA) to assess body composition in overweight and obese adolescents, compared with dual-energy X-ray absorptiometry (DXA) and hand-to-foot (HF) BIA. Body composition was assessed in fifty-three overweight or obese adolescents (BMI 27.9 (SD 4.1) kg/m2; aged 13-16 years) by DXA (Hologic QDR-4500; Hologic Inc., Bedford, MA, USA) and BIA (HF (BIA 101, RJL System, Detroit, IL, USA) and FF (Body Fat Monitor Scale BF-625, Tanita Corporation of America Inc., Arlington Heights, IL, USA; Téfal Bodymaster Vision, Téfal, Rumilly, France)). Bland-Altman tests showed that, compared with DXA, FF-Tanita and FF-Téfal underestimated (PTanita or FF-Téfal were much greater than those obtained with HF-BIA (-7.7 and +4.3, - 12.0 and +10.6 v. -2.1 and +6.7 kg respectively). The differences between FM assessed using the FF-Tanita or the FF-Téfal analyser and DXA increased with the waist:hip ratio, and were higher in boys than in girls. The major limiting factor of FF-BIA was the inter-individual variability in FM estimates. In conclusion, FF-BIA and DXA are not interchangeable methods. FF-BIA could be acceptable to assess body composition in large groups of overweight or obese adolescents, but cannot be recommended for body composition assessment in obese subjects because of the large errors in individual estimates.

Initiatives to Reduce Earthquake Risk of Developing Countries  

Science.gov (United States)

The seventeen-year-and-counting history of the Palo Alto-based nonprofit organization GeoHazards International (GHI) is the story of many initiatives within a larger initiative to increase the societal impact of geophysics and civil engineering. GHI's mission is to reduce death and suffering due to earthquakes and other natural hazards in the world's most vulnerable communities through preparedness, mitigation and advocacy. GHI works by raising awareness in these communities about their risk and about affordable methods to manage it, identifying and strengthening institutions in these communities to manage their risk, and advocating improvement in natural disaster management. Some of GHI's successful initiatives include: (1) creating an earthquake scenario for Quito, Ecuador that describes in lay terms the consequences for that city of a probable earthquake; (2) improving the curricula of Pakistani university courses about seismic retrofitting; (3) training employees of the Public Works Department of Delhi, India on assessing the seismic vulnerability of critical facilities such as a school, a hospital, a police headquarters, and city hall; (4) assessing the vulnerability of the Library of Tibetan Works and Archives in Dharamsala, India; (5) developing a seismic hazard reduction plan for a nonprofit organization in Kathmandu, Nepal that works to manage Nepal's seismic risk; and (6) assisting in the formulation of a resolution by the Council of the Organization for Economic Cooperation and Development (OECD) to promote school earthquake safety among OECD member countries. GHI's most important resource, in addition to its staff and Board of Trustees, is its members and volunteer advisors, who include some of the world's leading earth scientists, earthquake engineers, urban planners and architects, from the academic, public, private and nonprofit sectors. GHI is planning several exciting initiatives in the near future. One would oversee the design and construction of an earthquake- and tsunami-resistant structure in Sumatra to house a tsunami museum, a community training center, and offices of a local NGO that is preparing Padang for the next tsunami. This facility would be designed and built by a team of US and Indonesian academics, architects, engineers and students. Another initiative would launch a collaborative research program on school earthquake safety with the scientists and engineers from the US and the ten Islamic countries that comprise the Economic Cooperation Organization. Finally, GHI hopes to develop internet and satellite communication techniques that will allow earthquake risk managers in the US to interact with masons, government officials, engineers and architects in remote communities of vulnerable developing countries, closing the science and engineering divide.

Objective: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. Subjects and methods: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. Results: VF areas {>=} 130 cm{sup 2} were more prevalent among the elderly and among men. Adult females showed a stronger correlation between GV and %TBF-BIA. The other groups showed similar results and statistically significant correlations. Correlations between GV and phase angle were weak and not statistically significant. ROC Curves analyzes showed the following %TBF-BIA, which identified excess VF: for male subjects: 21.5% (adults) and 24.25% (elderly); for female subjects: 35.05% (adults) and 38.45% (elderly) with sensitivity of 78.6%, 82.1%, 83.3%, and 66.7%, and specificity of 70.6%, 62.5%, 79.1%, and 69%, respectively. Conclusion: BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction. (author)

Bioimpedance analysis: evaluation of leg-to-leg system based on pressure contact footpad electrodes.  

Science.gov (United States)

Conventional single frequency bioimpedance analysis (BIA) systems require technician placement of arm and leg gel electrodes, a suitable location for recumbent measurements, and a separate measurement of body weight. The aim of this study was to evaluate a new single frequency 50 KHz leg-to-leg bioimpedance analysis (BIA) system combined with a digital scale that employs stainless steel pressure-contact foot pad electrodes for standing impedance and body weight measurements. Healthy adults were evaluated for 1) electrode validity and 2) potential for body component estimation. Pressure-contact foot-pad electrode measured impedance was highly correlated with (N = 9, r = 0.99, P H2/Z) measured by the new system and two body composition components (total body water by 3H2O dilution (N = 144); and fat-free body mass, by underwater weighing and dual x-ray absorptiometry (N = 231)) was modeled using multiple regression analysis. Correlation coefficients for H2/Z alone versus body composition components were lower for leg-to-leg BIA than for arm-to-leg BIA; correlation coefficients and SEEs became similar for the leg-to-leg and arm-to-leg BIA systems with addition of three covariates (age, gender, and waist/hip circumference ratio) to regression models. The leg-to-leg pressure contact electrode BIA system has overall performance characteristics for impedance measurement and body composition analysis similar to conventional arm-to-leg gel electrode BIA and offers the advantage of increased speed and ease of measurement.

Agreement of Single- and Multi-Frequency Bioimpedance Measurements in Hemodialysis Patients: An Ancillary Study of the Frequent Hemodialysis Network Daily Trial.  

Science.gov (United States)

Background: Bioimpedance analysis (BIA) is well established to assess body composition. Agreements between single- and multi-frequency bioimpedance (SF-BIA, MF-BIS) measurements in subjects undergoing 6 or 3 times/week hemodialysis (HD) were analyzed. Methods: Total body water (TBW) and intra- and extracellular fluid (ICF, ECF) of subjects enrolled in the Frequent Hemodialysis Network (FHN) Daily Trial (www.clinicaltrials.gov No. NCT00264758) were measured with a Hydra 4200 at baseline (BL) and at 5 months (M5). Volumes were computed using SF (at 50 kHz) and MF approaches. Agreement was assessed by means of linear regression and Bland-Altman analysis and treatment effects by t test. Results: 35 subjects (17 on the more frequent regimen, 26 males, 20 African-American, 48 ± 9 years, pre-HD weight 84 ± 19 kg) were studied. Assessments with SF-BIA and MF-BIS correlated significantly at BL and M5 in both arms. No proportional errors, but systematic biases over the entire range of values were found at BL and M5. Agreement did not differ between subjects randomized to either HD treatment arm at both time points. MF-BIS appears to have better precision than SF-BIA allowing the observation of a significant treatment effect by the intervention [-1.5 (95% CI -2.5 to -0.5) l] on ECF, not found for ECF SF-BIA. Precision also affected the statistical power of the SF-BIA data in the current analysis. Conclusion: Both methods showed agreement without significant proportional errors regardless of HD frequency and can be used for longitudinal analyses. SF-BIA has lower precision which needs thorough consideration in the design of future trials with similar outcomes. © 2014 S. Karger AG, Basel. PMID:25402657

Agreement between different methods and predictive equations for resting energy expenditure in overweight and obese Brazilian men.  

Science.gov (United States)

Predictive equations and methods tend to overestimate or underestimate resting energy expenditure (REE) compared with indirect calorimetry (IC). This cross-sectional study aimed to evaluate the agreement between methods and equations for REE estimation of overweight and obese Brazilian men. Data from 48 healthy volunteers, ages 20 to 43 years and with body mass index ranging from 26.4 to 35.2, were collected between October 2008 and October 2009. REE was measured by IC, using Deltatrac (IC1) and KORR-MetaCheck (IC2) devices. It was estimated by bioelectrical impedance analysis (BIA) using tetrapolar (BIA1) and bipolar (BIA2) devices, and by the equations of Mifflin, World Health Organization/Food and Agriculture Organization/United Nations University, Fleisch, Horie-Waitzberg and Gonzalez, and Ireton-Jones. The association and agreement among the methods and equations were assessed by the interclass correlation coefficient, Bland-Altman analysis, and by the percentage of the difference between values obtained from the standard method and alternative methods and equations. Most methods showed high agreement with IC1. The highest agreements were found for Mifflin (-2.14%), Fleisch (-3.05%), Horie-Waitzberg and Gonzalez (4.41%), and BIA2 (5.25%). Similar results were shown by the Bland-Altman analyses. BIA2, followed by BIA1, Ireton-Jones, Mifflin, and Fleisch, showed the highest association with IC1. Thus, the Mifflin, Fleisch, Horie-Waitzberg and Gonzalez equations, and BIA2, were the most accurate methods for REE estimation in this study. However, because those equations have shown considerable variability, they should be used cautiously. In addition, the IC2 was not found to be an accurate method for REE estimation in overweight and obese men included in this study. PMID:22939443

Estimation of Body Composition Depends on Applied Device in Patients Undergoing Major Abdominal Surgery.  

Science.gov (United States)

Background: Bioelectrical impedance analysis (BIA) is a method used to estimate body compartments such as fat-free mass (FFM) and fat mass (FM). Two BIA devices, a single-frequency BIA (SF-BIA) device and a bioimpedance spectroscopy (BIS) approach, were compared to evaluate their reliability and to study whether their estimations resulted in similar classifications of body composition. Materials and Methods: In a prospective observational study, body composition was estimated by SF-BIA and BIS in 123 adult patients scheduled for major abdominal surgery. Measurement agreement for the continuous variables FFM and FM were analyzed by using the intraclass correlation coefficient (ICC), the mean differences, and their limits of agreement. Measurement differences were also visualized by Bland-Altman plots. For the dichotomized FFM index (FFMI) and FM index (FMI), interobserver agreement was calculated using Cohen ? statistics; the McNemar test was performed to compare the paired proportions. Results: Agreement for the continuous variables was almost perfect for FM (.86; 95% confidence interval [CI], .80-.90) and substantial for FFM (.78; 95% CI, .70-.84). For the dichotomous variables, the agreement was substantial for FMI (.67; 95% CI, .51-.83) and slight for FFMI (.19; 95% CI, .01-.37). BIS classified a larger proportion having a low FFMI and a high FMI. Conclusion: There were good ICCs between SF-BIA and BIS for FFM and FM. However, the mean differences were substantial, whereas the classification of body composition based on FFMI and FMI was influenced by the device. Therefore, BIA devices are not interchangeable.

Single- and multifrequency models for bioelectrical impedance analysis of body water compartments.  

Science.gov (United States)

The 1994 National Institutes of Health Technology Conference on bioelectrical impedance analysis (BIA) did not support the use of BIA under conditions that alter the normal relationship between the extracellular (ECW) and intracellular water (ICW) compartments. To extend applications of BIA to these populations, we investigated the accuracy and precision of seven previously published BIA models for the measurement of change in body water compartmentalization among individuals infused with lactated Ringer solution or administered a diuretic agent. Results were compared with dilution by using deuterium oxide and bromide combined with short-term changes of body weight. BIA, with use of proximal, tetrapolar electrodes, was measured from 5 to 500 kHz, including 50 kHz. Single-frequency, 50-kHz models did not accurately predict change in total body water, but the 50-kHz parallel model did accurately measure changes in ICW. The only model that accurately predicted change in ECW, ICW, and total body water was the 0/infinity-kHz parallel (Cole-Cole) multifrequency model. Use of the Hanai correction for mixing was less accurate. We conclude that the multifrequency Cole-Cole model is superior under conditions in which body water compartmentalization is altered from the normal state. PMID:10484581

Evaluating Solar Resource Data Obtained from Multiple Radiometers Deployed at the National Renewable Energy Laboratory: Preprint  

Energy Technology Data Exchange (ETDEWEB)

Solar radiation resource measurements from radiometers are used to predict and evaluate the performance of photovoltaic and concentrating solar power systems, validate satellite-based models for estimating solar resources, and advance research in solar forecasting and climate change. This study analyzes the performance of various commercially available radiometers used for measuring global horizontal irradiances (GHI) and direct normal irradiances (DNI). These include pyranometers, pyrheliometers, rotating shadowband irradiometers, and a pyranometer with a shading ring deployed at the National Renewable Energy Laboratory's Solar Radiation Research Laboratory (SRRL). The radiometers in this study were deployed for one year (from April 1, 2011, through March 31, 2012) and compared to measurements from radiometers with the lowest values of estimated measurement uncertainties for producing reference GHI and DNI.

Toward a visible light mediated photocyclization: Cu-based sensitizers for the synthesis of [5]helicene.  

Science.gov (United States)

A photochemical synthesis of [5]helicene employing a copper-based sensitizer 7 has been developed that avoids the disadvantages associated with the traditional UV light mediated method. The visible light mediated synthesis uses common glassware and a simple household light bulb without the competing formation of [2 + 2] cycloadducts, regioisomers, or the overoxidation product benzo[ghi]perylene 3. Preliminary results show that the reaction time can be significantly reduced through the use of a continuous flow strategy. PMID:22642645

The respiratory molybdoenzyme nitrate reductase (NarGHI) from Escherichia coli has been studied by protein film voltammetry, with the enzyme adsorbed on a rotating disk pyrolytic graphite edge (PGE) electrode. Catalytic voltammograms for nitrate reduction show a complex wave consisting of two components that vary with pH, nitrate concentration, and the presence of inhibitors. At micromolar levels of nitrate, the activity reaches a maximum value at approximately -25 mV and then decreases as th...

Nitrogen and Oxygen Regulation of Bacillus subtilis nasDEF Encoding NADH-Dependent Nitrite Reductase by TnrA and ResDE  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The nitrate and nitrite reductases of Bacillus subtilis have two different physiological functions. Under conditions of nitrogen limitation, these enzymes catalyze the reduction of nitrate via nitrite to ammonia for the anabolic incorporation of nitrogen into biomolecules. They also function catabolically in anaerobic respiration, which involves the use of nitrate and nitrite as terminal electron acceptors. Two distinct nitrate reductases, encoded by narGHI and nasBC, function in anabolic and...

The multidrug efflux regulator TtgV recognizes a wide range of structurally different effectors in solution and complexed with target DNA: evidence from isothermal titration calorimetry  

Digital Repository Infrastructure Vision for European Research (DRIVER)

TtgV modulates the expression of the ttgGHI operon, which encodes an efflux pump that extrudes a wide variety of chemicals including mono- and binuclear aromatic hydrocarbons, aliphatic alcohols, and antibiotics of dissimilar chemical structure. Using a 'lacZ fusion to the ttgG promoter, we show that the most efficient in vivo inducers were 1-naphthol, 2,3-dihydroxynaphthalene, 4-nitrotoluene, benzonitrile, and indole. The thermodynamic parameters for the binding of different effector molecul...

Non-magnetic semiconductor spin transistor  

CERN Document Server

We propose a spin transistor using only non-magnetic materials that exploits the characteristics of bulk inversion asymmetry (BIA) in (110) symmetric quantum wells. We show that extremely large spin splittings due to BIA are possible in (110) InAs/GaSb/AlSb heterostructures, which together with the enhanced spin decay times in (110) quantum wells demonstrates the potential for exploitation of BIA effects in semiconductor spintronics devices. Spin injection and detection is achieved using spin-dependent resonant interband tunneling and spin transistor action is realized through control of the electron spin lifetime in an InAs lateral transport channel using an applied electric field (Rashba effect). This device may also be used as a spin valve, or a magnetic field sensor. The electronic structure and spin relaxation times for the spin transistor proposed here are calculated using a nonperturbative 14-band k.p nanostructure model.

Prediction of fatness by standing 8-electrode bioimpedance: a multiethnic adolescent population.  

Science.gov (United States)

The objective of this study was to validate an 8-electrode bioimpedance analysis (BIA(8)) device (BC-418; Tanita, Tokyo, Japan) for use in populations of European, Maori, Pacific Island, and Asian adolescents. Healthy adolescents (215 M, 216 F; 129 Pacific Island, 120 Asian, 91 Maori, and 91 European; age range 12-19 years) were recruited by purposive sampling of high schools in Auckland, New Zealand. Weight, height, sitting height, leg length, waist circumference, and whole-body impedance were measured. Fat mass (FM) and fat-free mass (FFM) derived from the BIA(8) manufacturer's equations were compared with measurements by dual-energy X-ray absorptiometry (DXA). DXA-measured FFM was used as the reference to develop prediction equations based on impedance. A double cross-validation technique was applied. BIA(8) underestimated FM by 2.06 kg (P body fat (%BF) by 2.84% (P body composition in adolescents is ethnicity dependent. PMID:19498351

Ichthyometry and electrical bioimpedance analysis to estimate the body composition of tambatinga / Ictiometria e bioimpedância elétrica para estimativa da composição corporal do tambatinga  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Analisar composição corporal é relevante para caracterizar necessidades nutricionais e fase de terminação de peixes. Objetivou-se estudar a relação entre variáveis ictiométricas (peso, comprimentos total e padrão, densidade e rendimentos), bromatológicas (gordura, proteína, cinza e umidade) e aquela [...] s da análise por bioimpedância ou BIA (resistência, reatância, ângulo de fase e índices de composição), no híbrido tambatinga (Colossoma macropomum x Piaractus brachypomus). Em um viveiro não fertilizado, 520 juvenis foram cultivados com ração comercial. Com idade de 136 dias após a eclosão dos ovos, 37,69 g de peso, 12,96 cm de comprimento total, 15 peixes, colhidos ao acaso, foram anestesiados (eugenol) e submetidos à primeira de quatorze avaliações quinzenais (BIA e biometria). Após eutanásia foram dissecados e pesados: carcaça inteira com cabeça, filé e pele (CICFP), filé com pele (FCP) e resto da carcaça com cabeça (CCC). Juntos, FCP e CCC foram moídos e homogeneizados para análise bromatológica. Estimativas da composição corporal e de rendimentos do tambatinga, com modelos incluindo variáveis ictiométricas e da BIA, apresentaram coeficientes de correlação entre 0,81 (para o rendimento do FCP) e 1,00 (para cinzas totais). Analogamente, modelos com a inclusão apenas de variáveis da BIA mostram coeficientes de correlação entre 0,81 (rendimento do FCP e do CCC) e 0,98 (para cinzas totais). Portanto, no tambatinga, a técnica da BIA possibilita a estimativa do rendimento de filé com pele e composição corporal (umidade, gordura, cinza e proteína). Os melhores modelos agregam variáveis ictiométricas e da BIA. Abstract in english Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content [...] ) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of fourteen fortnightly assessments (BIA and biometry). After euthanasia, the following parts were weighed: whole carcass with the head, fillet, and skin (WC); fillet with skin (FS); and the remainder of the carcass with the head (CH). Together, FS and CH were ground and homogenized for the bromatological analyses. Estimates of the body composition and yields of tambatinga, with models including ichthyometric and BIA variables, showed correlation coefficients ranging from 0.81 (for the FS yield) to 1,00 (for the total ash). Similarly, models that included only BIA variables had correlation coefficients ranging from 0.81 (FS and CH yields) to 0.98 (for the total ash). Therefore, in tambatinga, the BIA technique allows the estimation of the yield of the fillet with skin and the body composition (water content, fat, ash, and protein). The best models combine ichthyometric and BIA variables.

Physiologic consequences of glucose transport and phosphoenolpyruvate node modifications in Bacillus subtilis 168.  

Science.gov (United States)

The phosphoenolpyruvate (PEP) node is an important carbon distribution point in the central metabolic networks; therefore, its modification is a common strategy employed for developing microbial production strains. In this study, mutants of Bacillus subtilis 168 were generated with deletions of pykA (which encodes pyruvate kinase), ptsG (which encodes the glucose-specific IICBA(Glc) component) or the ptsGHI operon [which encodes IICBA(Glc), HPr protein and enzyme I from the PEP:sugar phosphotransferase system (PTS)]. These modifications caused a reduction in the initial rate of [(14)C]-glucose import, corresponding to 10.99, 2.83 and 0.50% of that found in B. subtilis 168 for strains with inactive pykA, ptsG or ptsGHI genes, respectively. Characterization of derivative strains lacking 3-dehydroquinate synthase activity showed that inactivation of pykA leads to an 8-fold increase in carbon flow to the common aromatic pathway. Quantitative real-time PCR analyses of 76 genes from several functional classes revealed a carbon starvation transcriptional pattern that includes a partial gluconeogenic response and overexpression of genes encoding non-PTS glucose importers in the strains lacking functional pykA, ptsG or ptsGHI genes. A transcriptional response consistent with pyruvate limitation was also detected, which includes upregulation of genes encoding malic enzymes that generate pyruvate from malate. PMID:22846916

Models of the Compact Jet in GRS 1915+105  

CERN Document Server

In this article, models are constructed of the compact jet in GRS 1915+105 during an epoch of optimal data capture. On April 02, 2003, the object was observed in the hard X-ray/soft gamma ray band (INTEGRAL), hard X-ray band (RXTE), near IR (ESO/New Technology Telescope) and the VLBA (8.3 GHz and 15 GHz). The source was in a so-called "high plateau state." The large radio flux provides high signal to noise ratios in the radio images. Thus, one can image the jet out to large distances ($ > 10^{15}$ cm). This combined with the broadband coverage make this epoch the best suited for modeling the jet. The parametric method developed in the papers \\cite{ghi85,ghi89,ghi96,sam97} that has been successfully utilized in the realm of extragalactic radio jets is implemented. The basic model is one where external inverse Compton (EIC) scattering of accretion disk photons by jet plasma provides the hard X-ray powerlaw. Unlike AGN jets, it is found that the radio jet must be highly stratified in the transverse direction in ...

Modeling the Cumulative Effects of Social Exposures on Health: Moving beyond Disease-Specific Models  

Directory of Open Access Journals (Sweden)

Full Text Available The traditional explanatory models used in epidemiology are “disease specific”, identifying risk factors for specific health conditions. Yet social exposures lead to a generalized, cumulative health impact which may not be specific to one illness. Disease-specific models may therefore misestimate social factors’ effects on health. Using data from the Canadian Community Health Survey and Canada 2001 Census we construct and compare “disease-specific” and “generalized health impact” (GHI models to gauge the negative health effects of one social exposure: socioeconomic position (SEP. We use logistic and multinomial multilevel modeling with neighbourhood-level material deprivation, individual-level education and household income to compare and contrast the two approaches. In disease-specific models, the social determinants under study were each associated with the health conditions of interest. However, larger effect sizes were apparent when outcomes were modeled as compound health problems (0, 1, 2, or 3+ conditions using the GHI approach. To more accurately estimate social exposures’ impacts on population health, researchers should consider a GHI framework.

Amplification of the uvrA gene product of Escherichia coli to 7% of cellular protein by linkage to the p/sub L/ promoter of pKC30  

International Nuclear Information System (INIS)

Researchers have constructed a hybrid pKC30-uvrA plasmid (pGHY5003) in which transcription of the uvrA gene can be induced under p/sub L/ control to amplify the uvrA gene product to 7% of cellular protein. To construct pGHY5003, researchers developed a genetic selection using the basal level of expression (300C) from p/sub L/ in thermosensitive cI857 lysogens to isolate appropriately tailored repair genes inserted at the Hpa I site of pKC30 from recombinant DNA mixtures with a variety of products. In addition, a post-uv-irradiation radiolabeling method was adapted to screen inserts for temperature-inducible polypeptide synthesis directed by transcription under p/sub L/ control rapidly. This should prove generally useful for isolating genes inserted at the Hpa I site of plasmid pKC30 with the following characteristics: (1) genetically functional hybrid plasmids selected from a large population of exonucleolytically tailored fragments ligated into Hpa I of pKC30 and (2) production of high-level amplification for the gene product of interest by screening for post-uv-irradiation temperature inducibility of polypeptides synthesized from hybrid plasmids. The level of amplification obtained for the uvrA gene product from pGHY5003 is approximately 10,000-fold higher than estimates of the level of uvrA protein in logarithmic phase Escherichia coli

Estimating Solar Irradiance using a Geostationary Satellite  

Science.gov (United States)

A method to estimate global horizontal irradiance (GHI) at the surface using a geostationary satellite is presented. The spatial variation of ground and cloud albedo of California is characterized in the 0.55-0.75 im wavelength spectral region by analyzing a series of images from the visible channel on the GOES West satellite. Using these two characteristic albedo maps a cloud index is generated for each pixel in subsequent images as an estimate of the cloud fraction in that pixel. The cloud index is converted into a clear sky index which is then coupled with the modeled GHI under a clear sky to generate estimates of the GHI under the current cloud conditions. The model was applied to 914 images over 65 days and validated with ground truth measurements in California. The mean bias difference from 119 stations in the California Irrigation Management Information System was 6.7 W/m 2 (3.2%) and the root mean square difference was 78.6 W/m2 (21.9%) which is consistent with previously reported results for satellite algorithms. A Matlab-Java code to execute the model is documented.

Solar variability of four sites across the state of Colorado  

Energy Technology Data Exchange (ETDEWEB)

Solar Global Horizontal Irradiance (GHI) fluctuates on both short (seconds to hours) and long (days to months) timescales leading to variability of power produced by solar photovoltaic (PV) systems. Under a high PV penetration scenario, fluctuations on short time scales may require a supplementary spinning power source that can be ramped quickly, adding significant external cost to PV operation. In order to examine the smoothing effect of geographically distributed PV sites, GHI timeseries at 5 min resolution at four sites across the state of Colorado were analyzed. GHI at the four sites was found to be correlated due to synchronous changes in the solar zenith angle. However, coherence analysis showed that the sites became uncorrelated on time scales shorter than 3 h, resulting in smoother average output at short time scales. Likewise, extreme ramp rates were eliminated and the spread in ramp rate magnitude was significantly reduced when all four sites were averaged. Nevertheless, even for the averaged output, high frequency fluctuations in PV power output are relatively larger in magnitude than fluctuations expected from wind turbines. Our results allow estimation of the ancillary services required to operate distributed PV sites. (author)

Surface Radiation from GOES: A Physical Approach; Preprint  

Energy Technology Data Exchange (ETDEWEB)

Models to compute Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) have been in development over the last 3 decades. These models can be classified as empirical or physical, based on the approach. Empirical models relate ground based observations with satellite measurements and use these relations to compute surface radiation. Physical models consider the radiation received from the earth at the satellite and create retrievals to estimate surface radiation. While empirical methods have been traditionally used for computing surface radiation for the solar energy industry the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is an operational physical model from NOAA that computes GHI using the visible and infrared channel measurements from the GOES satellites. GSIP uses a two-stage scheme that first retrieves cloud properties and uses those properties in a radiative transfer model to calculate surface radiation. NREL, University of Wisconsin and NOAA have recently collaborated to adapt GSIP to create a 4 km GHI and DNI product every 30 minutes. This paper presents an outline of the methodology and a comprehensive validation using high quality ground based solar data from the National Oceanic and Atmospheric Administration (NOAA) Surface Radiation (SURFRAD) (http://www.srrb.noaa.gov/surfrad/sitepage.html) and Integrated Surface Insolation Study (ISIS) http://www.srrb.noaa.gov/isis/isissites.html), the Solar Radiation Research Laboratory (SRRL) at National Renewable Energy Laboratory (NREL), and Sun Spot One (SS1) stations.

Breast Implant–associated Anaplastic Large Cell Lymphoma: Updated Results from a Structured Expert Consultation Process  

Science.gov (United States)

Background: Despite increased cases published on breast implant–associated anaplastic large cell lymphoma (BIA-ALCL), important clinical issues remain unanswered. We conducted a second structured expert consultation process to rate statements related to the diagnosis, management, and surveillance of this disease, based on their interpretation of published evidence. Methods: A multidisciplinary panel of 12 experts was selected based on nominations from national specialty societies, academic department heads, and recognized researchers in the United States. Results: Panelists agreed that (1) this disease should be called “BIA-ALCL”; (2) late seromas occurring >1 year after breast implantation should be evaluated via ultrasound, and if a seroma is present, the fluid should be aspirated and sent for culture, cytology, flow cytometry, and cell block to an experienced hematopathologist; (3) surgical removal of the affected implant and capsule (as completely as possible) should occur, which is sufficient to eradicate capsule-confined BIA-ALCL; (4) surveillance should consist of clinical follow-up at least every 6 months for at least 5 years and breast ultrasound yearly for at least 2 years; and (5) BIA-ALCL is generally a biologically indolent disease with a good prognosis, unless it extends beyond the capsule and/or presents as a mass. They firmly disagreed with statements that chemotherapy and radiation therapy should be given to all patients with BIA-ALCL. Conclusions: Our assessment yielded consistent results on a number of key, incompletely addressed issues regarding BIA-ALCL, but additional research is needed to support these statement ratings and enhance our understanding of the biology, treatment, and outcomes associated with this disease.

Breast implant-associated ALK-negative anaplastic large cell lymphoma: a case report and discussion of possible pathogenesis.  

Science.gov (United States)

Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is a recently recognized clinical entity, with only 39 well-documented cases reported worldwide, including 3 fatalities. Because of its rarity, the clinical and pathologic features of this malignancy have yet to be fully defined. Moreover, the pathogenesis of ALCL in association with textured silicone gel breast implants is poorly understood. Here we report a case of BIA-ALCL arising in a 67-year-old woman with a mastectomy due to breast cancer followed by implantation of textured silicone gel breast prosthesis. The patient presented with breast enlargement and tenderness 8 years following reconstructive surgery. MRI revealed a fluid collection surrounding the affected breast implant. Pathologic examination confirmed the presence of malignant ALCL T cells that were CD30+, CD8+, CD15+, HLA-DR+, CD25+ ALK- and p53. A diagnosis of indolent BIA-ALCL was made since tumor cells were not found outside of the capsule. Interestingly, an extensive mixed lymphocytic infiltrate and ectopic lymphoid tissue (lymphoid neogenesis) adjacent to the fibrous implant capsule were present. The patient was treated with capsulectomy and implantation of new breast prostheses. Six months later, the patient was found to have BIA-ALCL involvement of an axillary lymph node with cytogenetic evolution of the tumor. To our knowledge, this is the sixth reported case of aggressive BIA-ALCL. Unique features of this case include the association with lymphoid neogenesis and the in vivo cytogenetic progression of the tumor. This case provides insight into the potential role of chronic inflammation and genetic instability in the pathogenesis of BIA-ALCL. PMID:23923082

Comparison of body composition by bioelectrical impedance analysis and dual-energy X-ray absorptiometry in Hispanic diabetics.  

Science.gov (United States)

OBJECTIVE: The purpose of this study was to compare Tanita tetrapolar foot-to-foot bioelectrical impedance analysis (Model TBF-310, Tanita Corporation of America, Inc, Arlington Heights, IL; Tanita-BIA) and fan beam dual-energy X-ray absorptiometry (Hologic Discovery A v12.6, Waltham, MA; DXA) in diabetic patients. METHODS: Seventy Hispanic diabetic participants (23 male, 47 female; mean age: 53.03 ± 10.32 yrs; mean weight: 81.45 ± 17.65 kg; and mean body mass index: 31.40 ± 6.80 kg/m(2)) were selected from the Loma Linda University En Balance culturally-sensitive Spanish diabetes education program using the baseline data. RESULTS: DXA vs Tanita-BIA fat mass (FM), percent fat mass (%FM), and fat-free mass (FFM) were compared using Pearson's (FM: 0.96, %FM: 0.91, and FFM: 0.95), and Spearman's rank (FM: 0.94, %FM: 0.91, and FFM: 0.93) correlation coefficients. Bland-Altman analyses were also used to compare the difference (DXA - BIA) vs average of DXA and BIA results and showed general agreement between the two methods. When Tanita-BIA was regressed onto DXA, the adjusted R(2) was: FM=0.91; %FM=0.83; FFM=0.90. Gender combined concordance correlations with 95% confidence intervals were calculated using a bootstrap re-sampling of the data and found high associations [FM: 0.93 (95% CI: 0.89, 0.96)], [%FM: 0.86 (95% CI: 0.79, 0.90)], and [FFM: 0.93 (95% CI: 0.89, 0.96)]. CONCLUSION: Tanita-BIA may provide valid measures of fat, percent body fat and fat-free mass in Hispanic diabetics, and could be a convenient and practical approach for assessment in community-based research.

Regression analysis, Bland-Altman plot analysis and intra-class correlation coefficient (ICC) were used to compare methods. RESULTS: Absolute agreement between DXA and BIA-man was poor for all measures of body composition (BF% -6.8% ± 3.7%, FM -3.1 ± 3.6 kg, FFM 5.7 ± 2.8 kg). BIA-Segal equation showed good absolute agreement with DXA for BF% (1.5% ± 1.5%), FM (1.0 ± 3.2 kg) and FFM (1.5 ± 2.6 kg), albeit the limits of agreement were wide. BIA-Gray equation showed good absolute agreement with DXA for FM (2.3 ± 4.1 kg), and smaller biases for BF% (0.05% ± 4.4%) and FFM (0.2 ± 2.9 kg), although wide limits of agreement. BIA-Gray and DXA showed the highest ICC among the pairs of methods. A good absolute agreement was observed between DXA and SKF for BF% (-2.3% ± 5.8%), FM (0.09 ± 4.7 kg), and FFM (2.4 ± 4.4 kg), although limits of agreement were wider and ICC between DXA and SKF for BF% indicated poor degree of reproducibility. CONCLUSION: These findings show that both BIA-Segal and BIA-Gray equations are suitable for BF%, FM and FFM estimations in overweight and obese women.

Comparison of two bioelectrical impedance analysis instruments for determining body composition in adolescent girls  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The purpose of this study was to compare fat-free mass (FFM) and percent body fat determined by two bio-electrical impedance analysis (BIA) instruments against criterion estimates determined by dual-energy x-ray absorptiometry (DXA) in a multi-racial/ethnic sample of adolescent girls. BIA was assessed in 151 girls (n=51 African-American; n=45 Hispanic; n=55 Caucasian; age 12.2 ± 1.2 yr) using the RJL Quantum II and the American Weights and Measures Body-Comp Scale (BCS). Percent body fat det...

Phase sensitive spectral domain interferometry for label free biomolecular interaction analysis and biosensing applications  

Science.gov (United States)

Biomolecular interaction analysis (BIA) plays vital role in wide variety of fields, which include biomedical research, pharmaceutical industry, medical diagnostics, and biotechnology industry. Study and quantification of interactions between natural biomolecules (proteins, enzymes, DNA) and artificially synthesized molecules (drugs) is routinely done using various labeled and label-free BIA techniques. Labeled BIA (Chemiluminescence, Fluorescence, Radioactive) techniques suffer from steric hindrance of labels on interaction site, difficulty of attaching labels to molecules, higher cost and time of assay development. Label free techniques with real time detection capabilities have demonstrated advantages over traditional labeled techniques. The gold standard for label free BIA is surface Plasmon resonance (SPR) that detects and quantifies the changes in refractive index of the ligand-analyte complex molecule with high sensitivity. Although SPR is a highly sensitive BIA technique, it requires custom-made sensor chips and is not well suited for highly multiplexed BIA required in high throughput applications. Moreover implementation of SPR on various biosensing platforms is limited. In this research work spectral domain phase sensitive interferometry (SD-PSI) has been developed for label-free BIA and biosensing applications to address limitations of SPR and other label free techniques. One distinct advantage of SD-PSI compared to other label-free techniques is that it does not require use of custom fabricated biosensor substrates. Laboratory grade, off-the-shelf glass or plastic substrates of suitable thickness with proper surface functionalization are used as biosensor chips. SD-PSI is tested on four separate BIA and biosensing platforms, which include multi-well plate, flow cell, fiber probe with integrated optics and fiber tip biosensor. Sensitivity of 33 ng/ml for anti-IgG is achieved using multi-well platform. Principle of coherence multiplexing for multi-channel label-free biosensing applications is introduced. Simultaneous interrogation of multiple biosensors is achievable with a single spectral domain phase sensitive interferometer by coding the individual sensograms in coherence-multiplexed channels. Experimental results demonstrating multiplexed quantitative biomolecular interaction analysis of antibodies binding to antigen coated functionalized biosensor chip surfaces on different platforms are presented.

Biosíntesis de alcaloides bencilisoquinolínicos  

Directory of Open Access Journals (Sweden)

Full Text Available Benzylisoquinoline alkaloid biosynthesis. The benzylisoquinoline alkaloids (BIA are specialized metabolites with an ancient phylogeneticdistribution, but still preserved in modern clades. Some of them, such as morphine, sanguinerine or berberine, are important for modernmedicine. This review discusses the highlights of the current state of the biosynthesis of BIA. There have been studies that show thebiosynthesis of 22 of these nitrogenous metabolites. In their formation there are 43 enzymes grouped into oxidoreductases, transferasesand lyases, which in some cases represent atypical examples of the manner in which the secondary metabolism diversification wasoriginated. Two of these examples are the cytochrome proteins P450 (P450, with catalytic activities for ABI route, or the norcoclaurinesynthase enzyme (NCS, which share substantial identity with defense allergenic proteins. Likewise, there are genetic advances thathave produced the characterization of 30 enzymes, allowing knowledge of regulatory processes. Another interesting aspect is thecompartmentation of the biosynthesis sites and accumulation of BIA, since in several cases they are spatially separated and in differentspecies, or in the same species several types of cells may be involved. This has suggested intra and intercellular transport of alkaloids,precursors and enzymes, and it has been documented berberine transport between the cytoplasm and the vacuoles of storage. The picturefor the biosynthesis of BIA has been constructed with exemplary studies of alkaloids with pharmacological importance.

Paleoecological interpretation of a Holocene sand body in the coastal area of Phetchaburi, Gulf of Thailand  

Directory of Open Access Journals (Sweden)

Full Text Available Faunal examination is made of 4 samples, 2 from the Recent Ban Laem Phak Bia sand spit, and 2 from the Holocene sand body of Ban Bang Ket. Fossil and modern assemblages are compared on the basis of overall composition, taxa abundances, and of autoecological investigation on life habit, substrate preference, feeding type, depth range and ecological meaning of the identified species. The Holocene assemblage of Ban Bang Ket, compared to the Recent one of Ban Laem Phak Bia, 1 exhibits generally similar overall composition and ecological structure, 2 contains much of the dominant species characterizing the modern assemblage, and 3includes all taxa that are members of the living molluscan community. On this basis, the molluscan assemblage of Ban Bang Ket results to be the Holocene counterpart of the modern one of Ban Laem Phak Bia, and reflects the same environmental conditions recorded for the latter. Thus, the sand body near Ban Bang Ket is interpreted as a Holocene equivalent of the sand spit of Ban Laem Phak Bia.

Applications of bioelectrical impedance analysis for body composition to epidemiologic studies.  

Science.gov (United States)

Bioelectrical impedance analysis (BIA) is a promising tool in the evaluation of body composition in large population studies because it is fast, is inexpensive, and does not require extensive operator training or cross-validation. The empiric nature of the relation between resistance and reactance measured by BIA and body composition has led to the development of equations that translate the raw data into liters of body water or kilograms of fat-free mass (FFM) or fat mass. These equations may not be easily transferred from one population to another if the populations differ significantly in important determinants of body composition such as age, obesity, and illness. I review two recent studies from the Framingham Heart Study in which BIA was first compared with dual-energy X-ray absorptiometry (DXA) as a validation technique, and then compared with the body mass index (BMI, in kg/m2) as an alternative estimate of body fat. BIA was a good predictor of DXA-derived FFM (r = 0.85-0.88, P < 0.001) and was superior to BMI as an estimator of body fat. PMID:8780363

Percent body fat estimations in college women using field and laboratory methods: a three-compartment model approach  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Methods used to estimate percent body fat can be classified as a laboratory or field technique. However, the validity of these methods compared to multiple-compartment models has not been fully established. This investigation sought to determine the validity of field and laboratory methods for estimating percent fat (%fat in healthy college-age women compared to the Siri three-compartment model (3C. Methods Thirty Caucasian women (21.1 ± 1.5 yrs; 164.8 ± 4.7 cm; 61.2 ± 6.8 kg had their %fat estimated by BIA using the BodyGram™ computer program (BIA-AK and population-specific equation (BIA-Lohman, NIR (Futrex® 6100/XL, a quadratic (SF3JPW and linear (SF3WB skinfold equation, air-displacement plethysmography (BP, and hydrostatic weighing (HW. Results All methods produced acceptable total error (TE values compared to the 3C model. Both laboratory methods produced similar TE values (HW, TE = 2.4%fat; BP, TE = 2.3%fat when compared to the 3C model, though a significant constant error (CE was detected for HW (1.5%fat, p ? 0.006. The field methods produced acceptable TE values ranging from 1.8 – 3.8 %fat. BIA-AK (TE = 1.8%fat yielded the lowest TE among the field methods, while BIA-Lohman (TE = 2.1%fat and NIR (TE = 2.7%fat produced lower TE values than both skinfold equations (TE > 2.7%fat compared to the 3C model. Additionally, the SF3JPW %fat estimation equation resulted in a significant CE (2.6%fat, p ? 0.007. Conclusion Data suggest that the BP and HW are valid laboratory methods when compared to the 3C model to estimate %fat in college-age Caucasian women. When the use of a laboratory method is not feasible, NIR, BIA-AK, BIA-Lohman, SF3JPW, and SF3WB are acceptable field methods to estimate %fat in this population.

A randomized controlled trial of long term effect of BCM guided fluid management in MHD patients (BOCOMO study: rationales and study design  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Bioimpedance analysis (BIA has been reported as helpful in identifying hypervolemia. Observation data showed that hypervolemic maintenance hemodialysis (MHD patients identified using BIA methods have higher mortality risk. However, it is not known if BIA-guided fluid management can improve MHD patients’ survival. The objectives of the BOCOMO study are to evaluate the outcome of BIA guided fluid management compared with standard care. Methods This is a multicenter, prospective, randomized, controlled trial. More than 1300 participants from 16 clinical sites will be included in the study. The enrolment period will last 6 months, and minimum length of follow-up will be 36 months. MHD patients aged between 18 years and 80 years who have been on MHD for at least 3 months and meet eligibility criteria will be invited to participate in the study. Participants will be randomized to BIA arm or control arm in a 1:1 ratio. A portable whole body bioimpedance spectroscopy device (BCM—Fresenius Medical Care D GmbH will be used for BIA measurement at baseline for both arms of the study. In the BIA arm, additional BCM measurements will be performed every 2 months. The primary intent-to-treat analysis will compare outcomes for a composite endpoint of death, acute myocardial infarction, stroke or incident peripheral arterial occlusive disease between groups. Secondary endpoints will include left ventricular wall thickness, blood pressure, medications, and incidence and length of hospitalization. Discussions Previous results regarding the benefit of strict fluid control are conflicting due to small sample sizes and unstable dry weight estimating methods. To our knowledge this is the first large-scale, multicentre, prospective, randomized controlled trial to assess whether BIS-guided volume management improves outcomes of MHD patients. The endpoints of the BOCOMO study are of utmost importance to health care providers. In order to obtain that aim, the study was designed with very careful important considerations related to the endpoints, sample size, inclusion criteria, exclusion criteria and so on. For example, annual mortality of Beijing MHD patients was around 10%. To reach statistical significance, the sample size will be very large. By using composite endpoint, the sample size becomes reasonable and feasible. Limiting inclusion to patients with urine volume less than 800 ml/day the day before dialysis session will limit confounding due to residual renal function effects on the measured parameters. Patients who had received BIS measurement within 3 months prior to enrolment are excluded as data from such measurements might lead to protocol violation. Although not all patients enrolled will be incident patients, we will record the vintage of dialysis in the multivariable analysis. Trial registration Current Controlled Trials NCT01509937

Measures of body fat in South Asian adults  

Science.gov (United States)

Background: South Asian people who originate from the Indian subcontinent have greater percent body fat (%BF) for the same body mass index (BMI) compared with white Caucasians. This has been implicated in their increased risk of type 2 diabetes and cardiovascular disease. There is limited information comparing different measures of body fat in this ethnic group. Objectives: The objectives of this study were: (1) to investigate the correlation of %BF measured by a foot-to-foot bioelectrical impedance analysis (FF-BIA) against the BOD POD, a method of air-displacement plethysmography, and (2) to determine the correlations of simple anthropometric measures, (that is, BMI, body adiposity index (BAI), waist circumference (WC), hip circumference (HC) and waist-to-hip ratio (WHR)) against the BOD POD measure of body fat. Methods: Eighty apparently healthy South Asian men and women were recruited from the community, and measurements of height, weight, WC, HC and body composition using Tanita FF-BIA and BOD POD were taken. Results: The mean±s.d. age of participants was 27.78±10.49 years, 42.5% were women, and the mean BMI was 22.68±3.51?kg?m?2. The mean body fat (%BF) calculated by FF-BIA and BOD POD was 21.94±7.88% and 26.20±8.47%, respectively. The %BF calculated by FF-BIA was highly correlated with the BOD POD (Pearson's r=0.83, P21?kg?m?2 than those with a BMI ?21?kg?m?2. Conclusion: The FF-BIA and BAI estimates of %BF are highly correlated with that of BOD POD among people of South Asian origin, although both methods somewhat underestimate % BF. Furthermore, their correlations with % BF from BOD POD are significantly weakened among men and women with a BMI ?21?kg?m?2. PMID:23712281

Different Techniques For Body Composition Assessment  

Directory of Open Access Journals (Sweden)

Full Text Available The inter-relationships and alter nativity of body composition variables derived from simple anthropometry [BMI and Skin Folds (SFs prediction equations] and Bioelectrical Impedance Analysis (BIA with dual energy x-ray (DXA of healthy sixty nine children (37 boys and 32 girls aged 9.24±1.73 years old were evaluated. The children recruited from public schools in Giza governorate. All of them had BMI ranged between 15th and 85th percentile and were assessed for body composition [percentage body fat (%BF, fat free mass (FFM; kilograms and body fat mass (BFM; kilograms] using Slaughter Skin Folds (SFs prediction equations, BIA and DXA. Repeated ANOVA showed significant differences among the three methods used for the studied variables (p<0.001. In general, Slaughter and BIA are significantly underestimated measured %BF. There is a high correlation between the BMI and both the estimated %BF and BFM (r = 0.67-0.91 for boys and r = 0.87 to 0.97 for the girls. Partial correlation among the estimated % BF derived from the three different methods in both genders revealed a high significant correlations between the estimated %BF derived from DXA and Slaughter equations (r = 0.76 for boys and 0.97 for girls. While the correlation between the estimated %BF derived from DXA and BIA was 0.77 for boys in contrast to girls where it is low significant correlation (r = 0.387. Results suggest that BIA has limited utility in estimating body composition, where as BMI and SFs seem to be more useful in estimating body composition. In conclusion all methods are significantly under estimated body fatness as determined by DXA and the various methods are not interchangeable.

Analysis and Prediction of Energy Production in Concentrating Photovoltaic (CPV Installations  

Directory of Open Access Journals (Sweden)

Full Text Available A method for the prediction of Energy Production (EP in Concentrating Photovoltaic (CPV installations is examined in this study. It presents a new method that predicts EP by using Global Horizontal Irradiation (GHI and the Photovoltaic Geographical Information System (PVGIS database, instead of Direct Normal Irradiation (DNI data, which are rarely recorded at most locations. EP at four Spanish CPV installations is analyzed: two are based on silicon solar cells and the other two on multi-junction III-V solar cells. The real EP is compared with the predicted EP. Two methods for EP prediction are presented. In the first preliminary method, a monthly Performance Ratio (PR is used as an arbitrary constant value (75% and an estimation of the DNI. The DNI estimation is obtained from GHI measurements and the PVGIS database. In the second method, a lineal model is proposed for the first time in this paper to obtain the predicted EP from the estimated DNI. This lineal model is the regression line that correlates the real monthly EP and the estimated DNI in 2009. This new method implies that the monthly PR is variable. Using the new method, the difference between the predicted and the real EP values is less than 2% for the annual EP and is in the range of 5.6%–16.1% for the monthly EP. The method that uses the variable monthly PR allows the prediction of the EP with reasonable accuracy. It is therefore possible to predict the CPV EP for any location, using only widely available GHI data and the PVGIS database.

Soil mobility of surface applied polyaromatic hydrocarbons in response to simulated rainfall.  

Science.gov (United States)

Polyaromatic hydrocarbons (PAHs) are emitted from a variety of sources and can accumulate on and within surface soil layers. To investigate the level of potential risk posed by surface contaminated soils, vertical soil column experiments were conducted to assess the mobility, when leached with simulated rainwater, of six selected PAHs (naphthalene, phenanthrene, fluoranthene, pyrene, benzo(e)pyrene and benzo(ghi)perylene) with contrasting hydrophobic characteristics and molecular weights/sizes. The only PAH found in the leachate within the experimental period of 26 days was naphthalene. The lack of migration of the other applied PAHs was consistent with their low mobilities within the soil columns which generally paralleled their log K oc values. Thus, only 2.3 % of fluoranthene, 1.8 % of pyrene, 0.2 % of benzo(e)pyrene and 0.4 % of benzo(ghi)perylene were translocated below the surface layer. The PAH distributions in the soil columns followed decreasing power relationships with 90 % reductions in the starting levels being shown to occur within a maximum average depth of 0.94 cm compared to an average starting depth of 0.5 cm. A simple predictive model identifies the extensive time periods, in excess of 10 years, required to mobilise 50 % of the benzo(e)pyrene and benzo(ghi)perylene from the surface soil layer. Although this reduces to between 2 and 7 years for fluoranthene and pyrene, it is concluded that the possibility of surface-applied PAHs reaching and contaminating a groundwater aquifer is unlikely.

Preferential sorption of planar contaminants in sediments from Lake Ketelmeer, The Netherlands  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Organic carbon normalized sediment-water distribution coefficients (KOC) of a series of in situ and (mass-labeled) added chlorobenzenes, PCBs, and PAHs were determined in an aged and a more recently deposited sediment layer from Lake Ketelmeer, The Netherlands, using the cosolvent method. The resulting log KOC's for both in situ and added compounds are rather high compared to literature data (up to 9.3 for benzo[ghi]perylene), with the ones in the recently deposited layer being generally high...

Region of Herpes Simplex Virus Type 1 Latency-Associated Transcript Sufficient for Wild-Type Spontaneous Reactivation Promotes Cell Survival in Tissue Culture  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The latency-associated transcript (LAT) is the only abundant herpes simplex virus type 1 (HSV-1) transcript expressed during latency. In the rabbit eye model, LAT null mutants do not reactivate efficiently from latency. We recently demonstrated that the LAT null mutant dLAT2903 induces increased levels of apoptosis in trigeminal ganglia of infected rabbits compared to LAT+ strains (G.-C. Perng, C. Jones, J.

TtgV Represses Two Different Promoters by Recognizing Different Sequences?  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Expression of the multidrug efflux pump ttgDEF and ttgGHI operons is modulated in vivo mainly by the TtgV repressor. TtgV is a multidrug recognition repressor that exhibits a DNA binding domain with a long interaction helix comprising residues 47 to 64. The pattern of expression of the two pumps is different in Pseudomonas putida: in the absence of effectors, the promoter for the ttgD gene is silent, whereas the ttgG gene is expressed at a high basal level. This correlates with the fact that ...

Identification of New Residues Involved in Intramolecular Signal Transmission in a Prokaryotic Transcriptional Repressor  

Digital Repository Infrastructure Vision for European Research (DRIVER)

TtgV is a member of the IclR family of transcriptional regulators. This regulator controls its own expression and that of the ttgGHI operon, which encodes an RND efflux pump. TtgV has two domains: a GAF-like domain harboring the effector-binding pocket and a helix-turn-helix (HTH) DNA-binding domain, which are linked by a long extended helix. When TtgV is bound to DNA, a kink at residue 86 in the extended helix gives rise to 2 helices. TtgV contacts DNA mainly through a canonical recognition ...

Solar Radiometric Data Quality Assessment of SIRS, SKYRAD and GNDRAD Measurements (Poster)  

Energy Technology Data Exchange (ETDEWEB)

Solar radiation is the driving force for the earth's weather and climate. Understanding the elements of this dynamic energy balance requires accurate measurements of broadband solar irradiance. Since the mid-1990's the ARM Program has deployed pyrheliometers and pyranometers for the measurement of direct normal irradiance (DNI), global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI), and upwelling shortwave (US) radiation at permanent and mobile field research sites. This poster summarizes the basis for assessing the broadband solar radiation data available from the SIRS, SKYRAD, and GNDRAD measurement systems and provides examples of data inspections.

Quantitative detection for plant virus's RNA-loading by dot-blot  

International Nuclear Information System (INIS)

A new method, RNA dot blot combined with direct determination of the radioactivity by BIO-Imaging Analyzer (dRH-dBIA) was used for detecting RNA of plant virus in infected plant tissue. This method was used for the influence of RNA-loading level of tobacco mosaic virus (TMV) in tobacco leave tissues after treatment of a plant hormone relatives (n-Propyl dihydro-jasmonate, PDJ) in the concentration range of 0.001-10 ppm. The results indicate that after PDJ application onto tobacco leaves for 3 days all PDJ treatments cause increase of TMV RNA-loading level except 0.001 ppm treatment, and the higher the concentration, the more obvious increase was observed. This phenomenon was confirmed with semi-leaf lesion spot on Nicotiana glutinosa as a local lesion host. The dRH-dBIA method is applicable in quantitative determination of RNA without obvious artificial influence

Ten best resources for conducting financing and benefit incidence analysis in resource-poor settings.  

Science.gov (United States)

Many low- and middle-income countries are seeking to reform their health financing systems to move towards universal coverage. This typically means that financing is based on people's ability to pay while, for service use, benefits are based on the need for health care. Financing incidence analysis (FIA) and benefit incidence analysis (BIA) are two popular tools used to assess equity in health systems financing and service use. FIA studies examine who pays for the health sector and how these contributions are distributed according to socioeconomic status (SES). BIA determines who benefits from health care spending, with recipients ranked by their relative SES. In this article, we identify 10 resources to assist researchers and policy makers seeking to undertake or interpret findings from financing and benefit incidence analyses in the health sector. The article pays particular attention to the data requirements, computations, methodological challenges and country level experiences with these types of analyses. PMID:25255919

Pharmaceutical applications of the benzylisoquinoline alkaloids from Argemone mexicana L.  

Science.gov (United States)

Argemone mexicana L. (Papaveraceae), accumulates benzylisoquinoline alkaloids, (BIA) derived from tyrosine. Although it was originated in the western region of the USA-Mexico border, it has spread to tropical and subtropical areas around the world. Today, it is used to treat different ailments, given to its antimicrobial, antiparasitic, antimalarial, pesticide, cytotoxic and neurological properties. These effects are related to the presence of different types of BIA's, such as benzophenanthridines (sanguinarine, chelerythrine), protoberberines (berberine) and protopines (protopine, allocryptopine). This review covers the historical medicinal uses of A. mexicana, as well as its current applications. The chemical bases of such effects are discussed in relation to the occurrence of the different types of alkaloids. The biochemical process involved in the synthesis of these types of alkaloids is also described. PMID:23978133

The aim of the current study was to assess phase angle (PA) and bioelectrical impedance vectors (BIVA) in adolescent (n = 105, 12-19 y) and adult (n = 90, 20-50 y) male athletes practicing varied sports modalities. Bioelectrical impedance analysis (BIA) was performed with a single-frequency tetrapolar impedance analyzer after the athletes had fasted overnight for 8 h. PA and BIVA were determined from BIA data. PA presented correlations (P basketball players. The BIVA confidence ellipses of adult and adolescent athletes were different (P basketball players who showed indications of decreased water retention and body cell mass and of increased water retention, respectively. PA and BIVA ellipses showed that the intense training routine of the athletes changed functional and hydration parameters and that the magnitude of these changes in adolescents may depend on the sport modality practiced.

Métodos y resultados: se realizó un estudio transversal poblacional in la ciudad de Ouro Preto, Brasil, en el 2006. Se distribuyó al azar a escolares de 6-15 años (n = 788), que se seleccionaron en función de la edad y el sexo, estratificados por la proporción de estudiantes en cada colegio de la ciudad. Se utilizó un análisis no paramétrico de curvas ROC para definir la sensibilidad y la especificidad para cada método estudiado empleando el método tetrapolar como referencia. El IMC y la BIA-PP fueron los más idóneos para el cribado de la obesidad en las etapas prepuberales y puberales puesto que presentan un equilibrio mejor entre la sensibilidad y la especificidad y un menor fallo de clasificación.

Abstract in english Background and aims: Childhood obesity is increasing dramatically in last decades.

Methods and results: A cross-sectional-based population study was performed in the city of Ouro Preto, Brazil, in 2006. Schoolchildren aged 6-15 years (n = 788) was randomly selected according to age and sex stratified by the proportion of students in each schools of the city. Nonparametric receiver operating characteristic (ROC) analysis was used to define the sensitivity and specificity for each method studied using the tetrapolar method as reference. The BMI and the BIA-FF were the most suitable for adiposity screening in pre-pubertal and pubertal stages because they present a better balance between sensitivity and specificity, and smaller misclassification. For post-pubertal boys, the BF-ST-D was the best body fat assessment method. Conclusion: The results suggest that BIA-FF and BMI are choice methods for obesity screening in mixed population and that the method choice for body fat screening must be done according to sexual maturity of boys and girls. The present study demonstrates the need to perform studies in wider mixed-race population to determine anthropometric parameters and to examine the predictive ability of methods and cut-offs here elucidated in the development of obesity.

Global horizontal irradiance clear sky models : implementation and analysis.  

Energy Technology Data Exchange (ETDEWEB)

Clear sky models estimate the terrestrial solar radiation under a cloudless sky as a function of the solar elevation angle, site altitude, aerosol concentration, water vapor, and various atmospheric conditions. This report provides an overview of a number of global horizontal irradiance (GHI) clear sky models from very simple to complex. Validation of clear-sky models requires comparison of model results to measured irradiance during clear-sky periods. To facilitate validation, we present a new algorithm for automatically identifying clear-sky periods in a time series of GHI measurements. We evaluate the performance of selected clear-sky models using measured data from 30 different sites, totaling about 300 site-years of data. We analyze the variation of these errors across time and location. In terms of error averaged over all locations and times, we found that complex models that correctly account for all the atmospheric parameters are slightly more accurate than other models, but, primarily at low elevations, comparable accuracy can be obtained from some simpler models. However, simpler models often exhibit errors that vary with time of day and season, whereas the errors for complex models vary less over time.

Pre- and syn-Ross orogenic granitoids at Drake Head and Kartografov Island, Oates Coast, northern Victoria Land, East Antarctica  

International Nuclear Information System (INIS)

The majority of the Oates Coast, northern Victoria Land granitoids, typified by those at Drake Head and Kartografov Island (Harald Bay), are monzogranites with lesser granodiorites and minor quartz-monzodiorite and syenogranite. All are plagioclase-K-feldspar-biotite granitoids with additional muscovite, garnet and/or hornblende, and are subalkaline and peraluminous. Berg Granite typifies the early Ordovician, Granite Harbour Instrusive (GHI) suite of the Ross Orogen at the Oates Coast. Granitoids from Kartografov Island have higher amounts of Fe+Mg+Ti and an ambiguous Rb-Sr geochronology: they could be either pre-Ross Orogeny in age, or syn-Ross Orogeny and representing a lower structural level of GHI. The Drake Head granite gneiss has a fractionated leuco-granite composition similar to Berg Granite, and is intruded by granite and granodiorite. Rb-Sr ages indicate that all are Neoproterozoic, although the granite gneiss result is probably an errorchron age, reflecting its less uniform nature (granodiorite:649 ± 30 Ma, initial ratio 0.7065 +/- 6; granite gneiss: 682 ± 140 Ma, initial ratio 0.7107 ± 50). These late Neoproterozoic granitoids provide a source for distinctive detrital zircon age components in extensive early Paleozoic turbidites of Australia-New Zealand-Antarctica.

Infrared Spectroscopy of Matrix-Isolated Polycyclic Aromatic Hydrocarbon Cations. Part 2; The Members of the Thermodynamically Most Favorable Series through Coronene  

Science.gov (United States)

Gaseous, ionized polycyclic aromatic hydrocarbons (PAHS) are thought to be responsible for a very common family of interstellar infrared emission bands. Here the near- and mid-infrared spectra of the cations of the five most thermodynamically favored PAHs up to coronene: phenanthrene, pyrene, benzo[e]pyrene, benzo-[ghi]perylene, and coronene, are presented to test this hypothesis. For those molecules that have been studied previously (pyrene, pyrene-d(sub 10), and coronene), band positions and relative intensities are in agreement. In all of these cases we report additional features. Absolute integrated absorbance values are given for the phenanthrene, perdeuteriophenanthrene, pyrene, benzo[ghi]perylene, and coronene cations. With the exception of coronene, the cation bands corresponding to the CC modes are typically 2-5 times more intense than those of the CH out-of-plane bending vibrations. For the cations, the CC stretching and CH in-plane bending modes give rise to bands that are an order of magnitude stronger than those of the neutral species, and the CH out-of-plane bends produce bands that are 5-20 times weaker than those of the neutral species. This behavior is similar to that found in most other PAH cations studied to date. The astronomical implications of these PAH cation spectra are also discussed.

Imperfect information and labor market bias against small and medium-sized enterprises: a Korean case  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We examine the labor market’s bias against small and medium-sized enterprises focusing on the Seoul Digital Industrial Complex case. We adopt Heckman’s approach to control selection bias, and use primary data from questionnaire surveys conducted at both firm and employee levels. We find that conventional firm-specific factors, such as wages, fringe benefits, and weekly work hours, primarily explain the labor market bias, but imperfect information is also positively associated with the bia...

Phenotypic variation of Epipactis helleborine x E. atrorubens hybrids in anthropogenic conditions  

Directory of Open Access Journals (Sweden)

Full Text Available Hybrid index has revealed the hybrid nature of helleborine populations growing on disturbed habitats in Bia?owie?a Forest and its western foreland. An analysis of eight traits has revealed that hybrids are morphologically more similar to E. helleborine. Hybrids differ from the typical E. helleborine first of all by: a very pubescent inflorescence axis, a considerable length of the subinflorescence internode. Also the range of phenotypical variation in these populations is shown.

For estimated lean mass the equations using body weight associated with biometrics measures can be proposed. For estimated fat mass the equations using body weight associated with bioimpedance analysis can be proposed.

Body composition and body fat distribution in relation to later risk of acute myocardial infarction: a Danish follow-up study  

DEFF Research Database (Denmark)

Introduction:Obesity is a modifiable risk factor for acute myocardial infarction (MI), but lean body mass (LBM) may also be an important factor. Low LBM may increase the risk of MI and LBM may modify the effect of obesity on MI. Thus, the inability of the classical anthropometric measures to evaluate LBM may lead to misclassification of MI risk in both lean and obese persons. We investigated the associations between incident MI and bioelectrical impedance analyses (BIA) derived measures of body composition in combination with body mass index (BMI) and anthropometric measures of body fat distribution.Methods and results:From 1993 to 1997, 27¿148 men and 29¿863 women, aged 50 to 64 year, were recruited into the Danish prospective study Diet, Cancer and Health. During 11.9 years of follow-up we identified 2028 cases of incident MI (1487 men and 541 women). BMI, waist circumference (WC), hip circumference and BIA of body composition including body fat mass (BFM), body fat percentage and LBM were measured at baseline. We used Cox proportional hazard models with age as time axis and performed extensive control for confounding. Weight, BMI, classical estimates of abdominal obesity and BIA estimates of obesity showed significant positive associations with incident MI. However, BFM adjusted for WC showed no association. Low LBM was associated with a higher risk of incident MI in both genders, and high LBM was associated with a higher risk in men.Conclusion:Obesity was positively associated with MI. Estimates of obesity achieved by BIA seemed not to add additional information to classical anthropometric measures regarding MI risk. Both high and low LBM may be positively associated with MI.International Journal of Obesity advance online publication, 1 February 2011; doi:10.1038/ijo.2010.278.

Body composition in heavy smokers: comparison of segmental bioelectrical impedance analysis and dual-energy x-ray absorptiometry.  

Science.gov (United States)

Smokers tend to have lower body mass index, on one hand, and increased abdominal obesity, on the other hand. Also, low levels of lean mass (LM) and bone mineral content (BMC) were found among older smokers compared with non-smokers. This altered body composition and its consequences raise the need for simple and reliable methods for assessment of body composition in smokers. This study aimed to compare body composition assessment by segmental bioelectrical impedance analysis (sBIA) with the reference method, dual energy X-ray absorptiometry (DEXA). Body composition was measured by sBIA (Tanita BC-545) and DEXA (Hologic) in 49 heavy smokers (>15 cigarettes/day, mean age 43.8?±?12.0). The comparison included correlations and differences between measurements obtained using the two methods as well as the Blande-Altman analysis. Whole-body fat mass (FM) and LM measured by the two methods were found to be highly correlated (r?>?0.9, p?Bland-Altman analysis revealed a good agreement for whole-body FM and LM, but a poor agreement for BMC. The segmental FM percentage and LM were also highly correlated (r?>?0.9, p?BIA significantly overestimated LM of the trunk and legs and underestimated the appendicular FM percentage. Verified by DEXA, sBIA provides reliable measures of whole-body LM, FM, and trunk FM in heavy smokers. A lesser degree of agreement was found for BMC, appendicular LM, and FM. PMID:25315614

The Secreted Esterase of Propionibacterium freudenreichii Has a Major Role in Cheese Lipolysis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Free fatty acids are important flavor compounds in cheese. Propionibacterium freudenreichii is the main agent of their release through lipolysis in Swiss cheese. Our aim was to identify the esterase(s) involved in lipolysis by P. freudenreichii. We targeted two previously identified esterases: one secreted esterase, PF#279, and one putative cell wall-anchored esterase, PF#774. To evaluate their role in lipolysis, we constructed overexpression and knockout mutants of P. freudenreichii CIRM-BIA...

Molecular Markers of Injury in Kidney Biopsy Specimens of Patients with Lupus Nephritis  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Prediction of prognosis in patients who have lupus nephritis is inadequate, limiting individualization of potentially toxic therapy. Advances in tissue molecular techniques offer new approaches to study mechanisms underlying kidney injury, and add to prognostic information gleaned from biopsy specimens. Analysis of mRNA expression in formalin-fixed, paraffin-embedded renal biopsy specimens is limited by both quantity and quality of RNA, requiring RNA pre-amplification, which can introduce bia...

On the Blind Interference Alignment over Homogeneous Block Fading Channels  

CERN Document Server

Staggered fading pattern between different users is crucial to interference alignment without CSIT, or so-called blind interference alignment (BIA). This special fading structure naturally arises from heterogeneous block fading setting, in which different users experience independent block fading with different coherent times. Jafar et al. prove that BIA can be applied in some special heterogeneous block fading channels, which are formed naturally or constructed artificially. In this paper, we show that in the context of a 2-user 2x1 broadcasting (BC) channel, staggered fading pattern can also be found in homogeneous block fading setting, in which both users experience independent fading with the same coherent time; and we propose a scheme to achieve the optimal 4/3 DoF for the homogenous setting by using BIA. Applying the proposed scheme, we further study a 2x1 BC network with K users undergoing homogeneous block fading. When K>=4, we show it is almost guaranteed that the transmitter can find two users among...

Defining "Acceptable Risk" for Earthquakes Worldwide  

Science.gov (United States)

The greatest and most rapidly growing earthquake risk for mortality is in developing countries. Further, earthquake risk management actions of the last 50 years have reduced the average lethality of earthquakes in earthquake-threatened industrialized countries. (This is separate from the trend of the increasing fiscal cost of earthquakes there.) Despite these clear trends, every new earthquake in developing countries is described in the media as a "wake up" call, announcing the risk these countries face. GeoHazards International (GHI) works at both the community and the policy levels to try to reduce earthquake risk. GHI reduces death and injury by helping vulnerable communities recognize their risk and the methods to manage it, by raising awareness of its risk, building local institutions to manage that risk, and strengthening schools to protect and train the community's future generations. At the policy level, GHI, in collaboration with research partners, is examining whether "acceptance" of these large risks by people in these countries and by international aid and development organizations explains the lack of activity in reducing these risks. The goal of this pilot project - The Global Earthquake Safety Initiative (GESI) - is to develop and evaluate a means of measuring the risk and the effectiveness of risk mitigation actions in the world's largest, most vulnerable cities: in short, to develop an earthquake risk index. One application of this index is to compare the risk and the risk mitigation effort of "comparable" cities. By this means, Lima, for example, can compare the risk of its citizens dying due to earthquakes with the risk of citizens in Santiago and Guayaquil. The authorities of Delhi and Islamabad can compare the relative risk from earthquakes of their school children. This index can be used to measure the effectiveness of alternate mitigation projects, to set goals for mitigation projects, and to plot progress meeting those goals. The preliminary results suggest that the comparisons of the participating cities are easily understood, and defensible. The evaluation of the sources of El Salvador's risk, made before the January 13th earthquake, pointed to the vulnerability made visible by the earthquake: earthquake-induced landslides, and difficulties with emergency response.

Size distribution of particle-phase molecular markers during a severe winter pollution episode.  

Science.gov (United States)

Airborne particulate matter was collected using filter samplers and cascade impactors in six size fractions below 1.8 microm during a severe winter air pollution event at three sites in the Central Valley of California. The smallest size fraction analyzed was 0.056 0.8) for retene, benzo[ghi]flouranthene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[e]pyrene, benzo[a]pyrene, perylene, indeno[1,2,3-cd]pyrene, benzo[ghi]perylene, coronene, MW302 polycyclic aromatic hydrocarbon (PAHs), 17beta(H)-21alpha(H)-30-norhopane, 17alpha(H)-21beta(H)-hopane, alphabetabeta-20R-C29-ethylcholestane, levoglucosan, and cholesterol. Of these compounds, levoglucosan was present in the highest concentration (60-2080 ng m(-3)) followed by cholesterol (6-35 ng m(-3)), PAHs (2-38 ng m(-3)), and hopanes and steranes (0-2 ng m(-3)). Nighttime concentrations were higher than daytime concentrations in all cases. Organic compound size distributions were generally similar to the total carbon size distributions during the nighttime but showed greater variability during the daytime. This may reflect the dominance of fresh emission in the stagnant surface layer during the evening hours and the presence of aged organic aerosol at the surface during the daytime when the atmosphere is better mixed. All of the measured organic compound particle size distributions had a single mode that peaked somewhere between 0.18 and 0.56 microm, but the width of each distribution varied by compound. Cholesterol generally had the broadest particle size distribution, while benzo[ghi]perylene and 17alpha(H)-21beta(H)-29-norhopane generally had sharper peaks. The difference between the size distributions of the various particle-phase organic compounds reflects the fact that these compounds exist in particles emitted from different sources. The results of the current study will prove useful for size-resolved source apportionment exercises. PMID:18800516

A comparison of approximation techniques for variance-based sensitivity analysis of biochemical reaction systems  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Sensitivity analysis is an indispensable tool for the analysis of complex systems. In a recent paper, we have introduced a thermodynamically consistent variance-based sensitivity analysis approach for studying the robustness and fragility properties of biochemical reaction systems under uncertainty in the standard chemical potentials of the activated complexes of the reactions and the standard chemical potentials of the molecular species. In that approach, key sensitivity indices were estimated by Monte Carlo sampling, which is computationally very demanding and impractical for large biochemical reaction systems. Computationally efficient algorithms are needed to make variance-based sensitivity analysis applicable to realistic cellular networks, modeled by biochemical reaction systems that consist of a large number of reactions and molecular species. Results We present four techniques, derivative approximation (DA, polynomial approximation (PA, Gauss-Hermite integration (GHI, and orthonormal Hermite approximation (OHA, for analytically approximating the variance-based sensitivity indices associated with a biochemical reaction system. By using a well-known model of the mitogen-activated protein kinase signaling cascade as a case study, we numerically compare the approximation quality of these techniques against traditional Monte Carlo sampling. Our results indicate that, although DA is computationally the most attractive technique, special care should be exercised when using it for sensitivity analysis, since it may only be accurate at low levels of uncertainty. On the other hand, PA, GHI, and OHA are computationally more demanding than DA but can work well at high levels of uncertainty. GHI results in a slightly better accuracy than PA, but it is more difficult to implement. OHA produces the most accurate approximation results and can be implemented in a straightforward manner. It turns out that the computational cost of the four approximation techniques considered in this paper is orders of magnitude smaller than traditional Monte Carlo estimation. Software, coded in MATLAB®, which implements all sensitivity analysis techniques discussed in this paper, is available free of charge. Conclusions Estimating variance-based sensitivity indices of a large biochemical reaction system is a computationally challenging task that can only be addressed via approximations. Among the methods presented in this paper, a technique based on orthonormal Hermite polynomials seems to be an acceptable candidate for the job, producing very good approximation results for a wide range of uncertainty levels in a fraction of the time required by traditional Monte Carlo sampling.

THE COST OF FOOD SECURITY VS. THE COST OF 'NO FOOD SECURITY’  

Directory of Open Access Journals (Sweden)

Full Text Available Widespread Hunger and Malnutrition is highly prevalent in India. It should be a subject of shame for every Indian. The cost benefit analysis of National Food Security Bill has been attempted in this paper. Is this a necessity for the economy like India where widespread Hunger and malnutrition is a major problem? According to GHI India's rank is 63rd out of 78 countries. Different cost estimates of Food Security Bill and the cost of 'no food security' have been compared.FSB is the need of the hour but it will dwindle our Fiscal deficit. Research is needed to be done so as to minimize the cost of FSB. History proves that when the people are secure and have enough to feed themselves, they are the useful productive members of the economy. Even the rich countries also spends on the basic needs of their people.

Supercritical fluid extraction of polycyclic aromatic hydrocarbons from liver samples and determination by HPLC-FL  

Energy Technology Data Exchange (ETDEWEB)

An extraction/clean-up procedure by SFE was developed for isolating PAHs from liver samples for subsequent HPLC-FL determination of ten PAHs in the enriched extract. Recoveries (90-115%) and RSD % ({<=} 7.7) were satisfactory. When applied to 11 samples of bird of prey (Tyto alba) protected species and classified of special interest, from the Galicia (Northwest to Spain), benzo[ghi]perylene and indeno[1,2,3-cd]pyrene were undetectable; chrysene and benzo[a]pyrene are only detected in one sample; benzo[a]anthracene and benzo[k]fluoranthene are only quantified in one sample and benzo[b]fluoranthene in two samples. The other PAHs, anthracene, fluoranthene and pyrene are present in almost all the samples. (orig.)

A Bayesian Model Committee Approach to Forecasting Global Solar Radiation  

CERN Document Server

This paper proposes to use a rather new modelling approach in the realm of solar radiation forecasting. In this work, two forecasting models: Autoregressive Moving Average (ARMA) and Neural Network (NN) models are combined to form a model committee. The Bayesian inference is used to affect a probability to each model in the committee. Hence, each model's predictions are weighted by their respective probability. The models are fitted to one year of hourly Global Horizontal Irradiance (GHI) measurements. Another year (the test set) is used for making genuine one hour ahead (h+1) out-of-sample forecast comparisons. The proposed approach is benchmarked against the persistence model. The very first results show an improvement brought by this approach.

Determination of polycyclic aromatic hydrocarbons from buzzards (Buteo buteo) and tawny owl (Strix aluco) by liquid chromatography with fluorescence detection.  

Science.gov (United States)

Supercritical fluid extraction was applied to the determination of naturally contaminated polycyclic aromatic hydrocarbons (PAHs) in bird tissue by liquid chromatography with fluorescence detection (LC-FL). Recoveries (> 90%) and relative standard deviations (< or = 7.7%) were satisfactory. The levels of 10 PAHs were analyzed in 6 classes of tissues (heart, liver, intestine, muscle, lung, and kidney) of 10 buzzards and 2 tawny owls, predatory birds from the Galicia (northwest Spain). The PAHs found most abundantly were pyrene, fluoranthene, benzo[a]anthracene, and anthracene. Chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene were not detected. Intestine, kidney, and lung were more polluted than other tissues.

Polycyclic aromatic hydrocarbons in farmed rainbow trout (Oncorhynchus mykiss) processed by traditional flue gas smoking and by liquid smoke flavourings.  

Science.gov (United States)

Polycyclic aromatic hydrocarbons (PAHs) were determined by high performance liquid chromatography (HPLC) method with fluorescence detection in rainbow trout fillets processed by traditional flue gas smoking and by liquid smoke flavourings, at low temperature (25 degrees C for 3h). Raw fillets were also investigated as control group. The following compounds, anthracene, fluoranthene, pyrene, benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene and benzo(ghi)perylene were detected in all samples and no significant difference (p>0.05) was found neither between fresh and processed samples nor between the two different smoking techniques, except for chrysene and benzo(b)fluoranthene. The results show that PAHs found in rainbow trout fillets could be considered as a consequence of environmental pollution and the mild smoking process described in the present study did not affect their concentrations.

Determination of the solubility of polycyclic aromatic hydrocarbons (PAH) from light heating oil in water; Bestimmung der Loeslichkeit von polycyclischen aromatischen Kohlenwasserstoffen aus Heizoel EL in Wasser  

Energy Technology Data Exchange (ETDEWEB)

The classification of mineral oil products according to their water-pollution potential (WGK) by the Commission for Classification of Water Hazardous Materials (KBwS) requires the availability of an appropriate data base. The solubility of PAHs of light heating oil in water was determined by a test method, which has already been described in the DGMK research report 556 ''Water Pollution Potential of Mineral Oils with High Content of Polycyclic Aromatic Hydrocarbons (Heavy Fuel Oil and Neutral Oil Extracts)''. This method was used to determine the solubility in the water phase of five PAHs in samples of light heating oil according to the German drinking water ordinance (Trinkwasser-Verordnung, TVO): benzo[a]pyrene, benzo[b]fluoroanthene, benzo[k]fluoroanthene, Indeno[1,2,3-cd]pyrene, benzo[ghi]perylene. The light heating oil samples were provided by two German refineries. (orig.)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Este artigo apresenta os resultados da determinação de 12 hidrocarbonetos policíclicos aromáticos (HPAs) em material particulado atmosférico (MPA) coletado na cidade de Niterói, RJ, Brasil. Amostras quinzenais de MPA foram coletadas durante 24 h, entre junho/2005 e maio/2006, no Campus da Universida [...] de Federal Fluminense, localizado em uma área residencial e comercial no Centro de Niterói. Um amostrador de grandes volumes e filtros de fibra de vidro foram usados na coleta de MPA. A concentração média de MPA foi 87 µg m-3. HPAs foram determinados por cromatografia líquida de alta eficiência e detecção por fluorescência após extração em banho de ultra-som. Os limites de detecção e de quantificação foram suficientemente baixos para permitir a detecção dos HPAs nas faixas de concentração observadas. Boas recuperações foram obtidas pela análise do material certificado SRM 1649a (NIST, USA). Fenantreno, benzo[a]antraceno, benzo[b]fluoranteno e benzo[ghi]perileno foram os HPAs predominantes. As concentrações dos HPAs individuais variaram entre 0,001 (antraceno) e 0,357 (fenantreno) ng m-3. As concentrações totais de HPAs variaram entre 0,141 e 1,235 ng m-3. As concentrações individuais e totais de HPAs não apresentaram correlação significativa com a temperatura, umidade relativa e a velocidade do vento. As razões fluoranteno/(fluoranteno + pireno) e benzo[ghi]perileno/indeno[1,2,3-cd]pireno indicaram que a principal fonte de HPAs na área estudada é a emissão veicular. Abstract in english This paper reports the determination of twelve polycyclic aromatic hydrocarbons (PAHs) in total suspended particulate (TSP) collected in Niterói City, RJ, Brazil. Bimonthly 24 h TSP samples were collected between June/2005 and May/2006 in the Campus of Federal Fluminense University that is located i [...] n a mixed residential and commercial neighbourhood in Niterói City Center, Rio de Janeiro State, Brazil. A high volume sampler and glass fibber filters were used to TSP sampling. A mean TSP concentration of 87 µg m-3 was found. PAHs were determined by high-performance liquid chromatography with fluorescence detection following ultrasonic extraction. Limits of detection and of quantification were sufficiently low to accomplish PAH determination in the observed concentration ranges. Good PAH recoveries were obtained by analysis of SRM 1649a (NIST, USA). Phenanthrene, benzo[a]anthracene, benzo[b]fluoranthene and benzo[ghi]perylene were the predominating PAHs. Individual PAH concentrations varied between 0.001 (anthracene) and 0.357 (phenanthrene) ng m-3. Total PAH concentrations varied between 0.141 and 1.235 ng m-3. Individual and total PAH concentrations were not correlated with temperature, relative humidity or wind velocity. The ratios fluoranthene/(fluoranthene + pyrene) and benzo[ghi]perylene/indene[1,2,3-cd]pyrene indicated the main source of PAHs in the studied area was vehicular emission.

Selective clean-up for polynuclear aromatic compounds in airborne particles and soil  

International Nuclear Information System (INIS)

Urban air particulate matter, internal combustion engine particulate emissions, gas turbine particulate emissions and soil were analysed for polynuclear aromatic compounds. Polynuclear aromatic compounds were isolated by adsorption chromatography on XAD-2. Polynuclear aromatic hydrocarbons (PAHs), polynuclear aromatic ketones and nitro-PAHs were obtained together in the aromatic fraction, while interfering compounds were absent. Glass capillary gas chromatography with the stationary phases OV-1, SE-54, Dexsil 300 and OV-25 was performed, and benzo(a)pyrene, 7-H-benz(de)anthracene-7-one and related compounds were identified. Differences between PAH profiles are discussed. It is concluded that cyclopenta(cd)pyrene and benzo(ghi)fluoranthene are rapidly decomposed in the atmosphere. 7-H-Benz(de)anthracene-7-one and 6-H-benzo(cd)pyrene-6-one are degraded during atmospheric exposure at a similar rate to benzo(a)pyrene, and nitro-derivatives are not formed in substantial amounts

Evaluation of errors made in solar irradiance estimation due to averaging the Angstrom turbidity coefficient  

Science.gov (United States)

Even though the monitoring of solar radiation experienced a vast progress in the recent years both in terms of expanding the measurement networks and increasing the data quality, the number of stations is still too small to achieve accurate global coverage. Alternatively, various models for estimating solar radiation are exploited in many applications. Choosing a model is often limited by the availability of the meteorological parameters required for its running. In many cases the current values of the parameters are replaced with daily, monthly or even yearly average values. This paper deals with the evaluation of the error made in estimating global solar irradiance by using an average value of the Angstrom turbidity coefficient instead of its current value. A simple equation relating the relative variation of the global solar irradiance and the relative variation of the Angstrom turbidity coefficient is established. The theoretical result is complemented by a quantitative assessment of the errors made when hourly, daily, monthly or yearly average values of the Angstrom turbidity coefficient are used at the entry of a parametric solar irradiance model. The study was conducted with data recorded in 2012 at two AERONET stations in Romania. It is shown that the relative errors in estimating global solar irradiance (GHI) due to inadequate consideration of Angstrom turbidity coefficient may be very high, even exceeding 20%. However, when an hourly or a daily average value is used instead of the current value of the Angstrom turbidity coefficient, the relative errors are acceptably small, in general less than 5%. All results prove that in order to correctly reproduce GHI for various particular aerosol loadings of the atmosphere, the parametric models should rely on hourly or daily Angstrom turbidity coefficient values rather than on the more usual monthly or yearly average data, if currently measured data is not available.

Using AERONET to complement irradiance networks on the validation of satellite-based estimations  

Science.gov (United States)

Long-term measurements of surface solar irradiance (SSI) are essential for predicting the production of solar energy conversion systems. Ground-based SSIs are also needed for validation and calibration of models which convert satellite images into down-welling irradiances. Unfortunately, well-controlled data are publicly available for only a limited number of locations, especially when it comes to beam normal irradiance (BNI). In the Middle East particularly, there is only one publicly available research-class station: the Sede Boqer station, monitored by the BSRN (Baseline Surface Radiation Network). Thus, estimations of SSIs have been so far difficult to validate in this region. Besides irradiance networks, AERONET (Aerosol Robotic network) program provides long-term and public accessible sun photometer measurements. Its main goal is to provide validation data for satellite retrievals of aerosol optical properties. Various atmospheric properties are measured: aerosol optical depth at several wavelengths, water vapor amount, Angstrom coefficients. These data can be utilized for computation of SSI in cloudless sky by means of a radiative transfer model (RTM). The appropriate conversion of AERONET atmospheric properties into irradiances would provide additional in-situ irradiance data. In this work, we select the AERONET data which are relevant for irradiance calculation, compute the direct and global irradiances using the RTM LibRadTran and validate the outcomes with nearest actual irradiance measurements. The comparisons are made in the Middle East region. At Sede Boqer where AERONET and BSRN measurements are simultaneously available, the standard-deviation obtained is only 6% for BNI and 5% for GHI (global horizontal irradiance) between the computed and the measured hourly mean irradiances (see the attached figure). When the AERONET and BSRN stations considered are 100 km away, the standard-deviation between actually measured and AERONET-derived irradiances amounts to 9% for GHI and 20% for BNI.

Oxygen isotope geochemistry of the Granite Harbour Intrusives, Wilson Terrane, Northern Victoria Land, Antarctica  

International Nuclear Information System (INIS)

The oxygen and strontium isotope compositions of the Cambro-Ordovician granitoids cropping out in the Wilson Terrane (Granite Harbour Intrusives-GHI) constrain the petrological evolution of the magmatism in Antarctica, related to the Ross Orogeny. The measured ?18OWR values of three intrusives define three different compositional groups: the metaluminous rocks (MAG), with ?18OWR ranging from 6.9 (olivine gabbro) to 11.4 %o (monzogranite); the unaltered peraluminous granites (PAG), having ?18OWR values ranging from 10.6 to 13.2 %o, and the foliated peraluminous leucogranites (SKG), characterized by ?18OWR values above 14 %o. The analysis of equilibrium mineral assemblages indicates that the high ?18OWR values are magmatic and unaffected by low-temperature processes. A few peraluminous granites sampled in the vicinity of Cenozoic intrusions show anomalously low ?18OWR, due to meteoric-hydrothermal alteration. The isotopic data indicate that the coeval and spatially related metaluminous mafic and felsic intrusives forming the GHI were not comagmatic: the mafic and intermediate rocks were likely derived from lower crustal contamination of a pristine basaltic magma; their ?18OWR values were also increased during emplacement, due to the interaction with the adjacent 18O-rich hydrous felsic magmas (mixing)rich hydrous felsic magmas (mixing). Oxygen isotope data indicate that the crustal sources producing the granite harbor intrusives were not homogeneous: the felsic metaluminous intrusives were produced by partial melting of fertile rock with possible igneous origin, whereas partial melting of a metapelitic source rock is claimed for the genesis of the peraluminous granites.

Direct evidence for nitrogen ligation to the high stability semiquinone intermediate in Escherichia coli nitrate reductase A.  

Science.gov (United States)

The membrane-bound heterotrimeric nitrate reductase A (NarGHI) catalyzes the oxidation of quinols in the cytoplasmic membrane of Escherichia coli and reduces nitrate to nitrite in the cytoplasm. The enzyme strongly stabilizes a menasemiquinone intermediate at a quinol oxidation site (Q(D)) located in the vicinity of the distal heme b(D). Here molecular details of the interaction between the semiquinone radical and the protein environment have been provided using advanced multifrequency pulsed EPR methods. (14)N and (15)N ESEEM and HYSCORE measurements carried out at X-band ( approximately 9.7 GHz) on the wild-type enzyme or the enzyme uniformly labeled with (15)N nuclei reveal an interaction between the semiquinone and a single nitrogen nucleus. The isotropic hyperfine coupling constant A(iso)((14)N) approximately 0.8 MHz shows that it occurs via an H-bond to one of the quinone carbonyl group. Using (14)N ESEEM and HYSCORE spectroscopies at a lower frequency (S-band, approximately 3.4 GHz), the (14)N nuclear quadrupolar parameters of the interacting nitrogen nucleus (kappa = 0.49, eta = 0.50) were determined and correspond to those of a histidine N(delta), assigned to the heme b(D) ligand His-66 residue. Moreover S-band (15)N ESEEM spectra enabled us to directly measure the anisotropic part of the nitrogen hyperfine interaction (T((15)N) = 0.16 MHz). A distance of approximately 2.2 Abetween the carbonyl oxygen and the nitrogen could then be calculated. Mechanistic implications of these results are discussed in the context of the peculiar properties of the menasemiquinone intermediate stabilized at the Q(D) site of NarGHI. PMID:19892705

Impact of aerosols on the forecast accuracy of solar irradiance calculated by a numerical weather prediction model  

Science.gov (United States)

The impact of aerosols on the forecast accuracy of solar irradiance calculated by a fine-scale, one day-ahead, and operational numerical weather prediction model (NWP) is investigated in this study. In order to investigate the impact of aerosols only, the clear sky period is chosen, which is defined as when there are no clouds in the observation data and in the forecast data at the same time. The evaluation of the forecast accuracy of the solar irradiance is done at a single observation point that is sometimes affected by aerosol events. The analysis period is one year from April 2010 to March 2011. During the clear sky period, the root mean square errors (RMSE) of the global horizontal irradiance (GHI), direct normal irradiance (DNI), and diffuse horizontal irradiance (DHI) are 40.0 W m-2, 84.0 Wm-2, and 47.9 W m-2, respectively. During one extreme event, the RMSEs of the GHI, DNI, and DHI are 70.1 W m-2, 211.6 W m-2, and 141.7 W m-2, respectively. It is revealed that the extreme events were caused by aerosols such as dust or haze. In order to investigate the impact of the aerosols, the sensitivity experiments of the aerosol optical depth (AOD) for the extreme events are executed. The best result is obtained by changing the AOD to 2.5 times the original AOD. This changed AOD is consistent with the satellite observation. Thus, it is our conclusion that an accurate aerosol forecast is important for the forecast accuracy of the solar irradiance.

A transfer function for the prediction of gas hydrate inventories in marine sediments  

Directory of Open Access Journals (Sweden)

Full Text Available A simple prognostic tool for gas hydrate (GH quantification in marine sediments is presented based on a diagenetic transport-reaction model approach. One of the most crucial factors for the application of diagenetic models is the accurate formulation of microbial degradation rates of particulate organic carbon (POC and the coupled biogenic CH4 formation. Wallmann et al. (2006 suggested a kinetic formulation considering the ageing effects of POC and accumulation of reaction products (CH4, CO2 in the pore water. This model is applied to data sets of several ODP sites in order to test its general validity. Based on a thorough parameter analysis considering a wide range of environmental conditions, the POC accumulation rate (POCar in g/cm2/yr and the thickness of the gas hydrate stability zone (GHSZ in m were identified as the most important and independent controls for biogenic GH formation. Hence, depth-integrated GH inventories in marine sediments (GHI in g of CH4 per cm2 seafloor area can be estimated as:

GHI = a · POCar · GHSZb · exp (?GHSZc/POCar/d + e

with a = 0.00214, b = 1.234, c = ?3.339, d = 0.3148, e = ?10.265.

Several tests indicate that the transfer function gives a realistic approximation of the minimum potential GH inventory of low gas flux (LGF systems. The overall advantage of the presented function is its simplicity compared to complex numerical models: only two easily accessible parameters are needed.

This methodology, with historical images from archives, represents a fundamental tool to separate catastrophic and non-catastrophic glacial flow periods.

Efecto de la realimentación en la composición corporal de mujeres con anorexia nerviosa restrictiva: antropometría frente a impedancia bioeléctrica / Effect of refeeding on the body composition of females with restrictive anorexia nervosa: anthropometry versus bioelectrical impedance  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivo: Evaluar la composición corporal en un grupo de pacientes desnutridas con anorexia nerviosa, respecto de controles sanas, antes y después del soporte nutricional, mediante antropometría y bioimpedancia. Métodos: Estudio observacional prospectivo. Se realizó una antropometría completa y un a [...] nálisis de bioimpedancia a 12 mujeres con anorexia nerviosa restrictiva (24,5 años) al ingreso hospitalario y semanalmente durante la realimentación. El grupo control estuvo formado por 24 mujeres sanas (21 años). Se aplicaron los test t-Student, U-Mann-Whitney, t-Student para medidas repetidas o Wilcoxon. La concordancia entre antropometría y BIA se analizó mediante el coeficiente de correlación intraclase y Bland-Altman. Resultados: Las pacientes mejoraron significativamente todos los índices de composición corporal a lo largo de la estancia hospitalaria, aunque sus valores al alta siguieron siendo menores que los de las controles. La media de peso ganado fue 5,22 kg (DE: 1,42), de los que el 51,4% fueron masa grasa, con distribución central preferentemente. En las controles la ecuación de BIA que mejor concuerda con antropometría es la de Sun (CCI = 0,896); en las pacientes la concordancia fue más débil, al ingreso y al alta. Conclusiones: La realimentación produce una ganancia ponderal, fundamentalmente a expensas de masa grasa, con distribución central; no se consigue restablecer el estado nutricional. La concordancia entre antropometría y bioimpedancia para el estudio de la composición corporal es aceptable, especialmente en sujetos sanos. Se recomienda emplear antropometría, si no se dispone de BIA vectorial o algún método gold estandard para el análisis de la composición corporal, en casos de alteraciones importantes en la composición corporal y/o el balance hídrico. Abstract in english Objective: To assess the body composition in a group of malnourished patients with anorexia nervosa as compared to healthy controls, before and after nutritional support, by means of anthropometry and bioimpedance. Methods: Prospective observational study. Complete anthropometry was performed as wel [...] l as bioimpedance analysis in 12 women (24.5 years) with restrictive anorexia nervosa at hospital admission and weekly thereafter during re-feeding. The control group was formed by 24 healthy women (21 years). The Student's t test, the Mann-Whitney U test, the Student's t test for repeated measurements, and the Wilcoxon's test were applied. The level of agreement between anthropometry and BIA was calculated by the interclass correlation coefficient and the Bland-Altman s test. Results: The patients had significant improvements in all indexes of body composition throughout their hospital staying although their values at discharge still were lower than those of the control subjects. The average weight gain was 5.22 kg (SD: 1.42), of which 51.4% was fat mass, preferentially centrally distributed. In the control subjects, the BIA equation that correlated the best with anthropometrics was Sun s equation (CCI = 0.896); in the patients, the level of agreement was weaker, both at hospital admission and at hospital discharge. Conclusions: Re-feeding produces weight gain, essentially at the expense of fat mass, which is centrally distributed; the nutritional status is not reestablished. The level of agreement between anthropometry and bioimpedance for studying body composition is acceptable, especially in healthy subjects. In those cases with severe changes in body composition and/or water balance, anthropometry is recommended when vectorial BIA or some other gold standard method are not available for the analysis of body composition.

En el caso de deportistas, además, permitiría optimizar su rendimiento deportivo. Por consiguiente, el presente estudio s [...] e planteó como primer objetivo comparar diferentes métodos de estudio del porcentaje de masa grasa de deportistas con LMC. Y como objetivo secundario, identificar alguna ecuación que permita predecir los niveles de masa grasa de manera más económica, sencilla, rápida y no invasiva. Se diseño un estudio observacional y transversal en el que participaron voluntariamente 8 deportistas varones con LMC a nivel o por debajo de T5 que compiten a nivel nacional. El porcentaje de masa grasa corporal de los participantes se determinó mediante tres metodologías: densitometría (DEXA), antropometría convencional (Ecuación de Siri) e impedancia bioeléctrica (BIA). Este protocolo fue aprobado por un Comité de Ética Institucional. El porcentaje de masa grasa presentado por jugadores de baloncesto en silla de ruedas tras someterse al método de referencia (DEXA) fue del 28,76±9,16%. El análisis de concordancia de Bland-Altman entre métodos sugiere que tanto la antropometría convencional como la BIA subestiman el porcentaje de masa grasa de deportistas con LMC. la ecuación de predicción obtenida fue: Masa Grasa (%)= 1,9197 (pliegue tríceps (mm)) + 6,5063. Tanto las técnicas antropométricas convencionales como la propia BIA subestiman la masa grasa en deportistas con LMC. Asimismo se ha identificado una ecuación de regresión para la predicción del porcentaje de masa grasa de bajo coste y aplicable en cualquier entorno. Abstract in english The assessment of fat mass (FM) is of great interest for people with chronic spinal cord injury (SCI) given that morbidity and mortality from cardiovascular disease are greater and occur earlier in this group. Furthermore, it may play a key role improving physical performance in athletes with SCI. F [...] or the reasons already mentioned, the current study was designed to compare different methods for assessing FM in athletes with SCI. A secondary objective was to identify a predictive equation for FM in this group that is easily reproducible elsewhere. A total of 8 male athletes with complete SCI at or below the 5th thoracic level (T5) competing in a national league volunteered for this study. The percentage of FM was assessed by three different methods: conventional anthropometry (Siri equation), bioelectrical impedance analysis (BIA) and densitometry (DEXA). This research was conducted in full accordance with ethical principles, including the World Medical Association Declaration of Helsinki (version, 2002). Furthermore, the present protocol was approved by an Institutional Ethics Committee. Mean percentage of FM assessed by DXA was 28.76±9.16%. Moreover, Bland-Altman plots suggested conventional anthropometry and BIA underestimated fat mass percentage in this group. Lastly, a predictive equation for fat mass was established as follows: FM (%)=1.9197 (triceps skinfold thickness (mm))+6.5063. It was concluded that both conventional anthropometry and BIA underestimated fat mass in athletes with chronic SCI. Furthermore, a predictive equation of fat mass was recommended for this group due to its low cost and wide availability in any clinical setting.

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese OBJETIVO: Comparar o ultrassom (US) portátil e a bioimpedância elétrica (BIA) com as dobras cutâneas (DC) para estimar o percentual de gordura corporal em adultos. MÉTODOS: Foram avaliadas 195 militares, sexo masculino, sendo coletados: peso, estatura, percentual de gordura por bioimpedância, dobras [...] cutâneas e ultrassom (US) em nove pontos (tríceps, subescapular, bíceps, peitoral, médio axilar, abdominal, suprailíaca, coxa e panturrilha). Além da estatística descritiva, foram utilizados gráficos de dispersão, o teste Kolmogorov-Smirnov, coeficiente de correlação ? (rho) de Spearman, o Wilcoxon Signed Ranks Test e a regressão linear para a elaboração de uma nova equação para a estimativa do percentual de gordura corporal em adultos jovens (do sexo masculino). RESULTADOS: O grupo apresentou idade média de 23,07 ± 7,55 anos, para peso e estatura os valores da média e desvio padrão foram: 72,65 ± 10,40 kg; 1,74 ± 0,06 metros, respectivamente. Comparando os resultados entre US e DC, verificaram-se correlações significativas para todos os pontos avaliados, sendo a prega da coxa a com maior correlação, seguida pelo peitoral. Comparando-se os três métodos, o US apresentou melhor correlação com a BIA do que com as DC. Pode-se propor uma nova equação de estimativa do percentual de gordura por US, que apresentou uma melhor correlação com o método das DC do que aquela utilizada pelo próprio equipamento.

Abstract in english INTRODUCTIONS E OBJECTIVE: To compare portable ultrasound (US) and bioimpedance analysis (BIA) with skinfolds (SF) to estimate body fat percentage in adults. METHODS: 195 military men were assessed and they had their weight, height, body fat by bioimpedance, skinfold in 9 points and ultrasound (US) [...] collected. Linear Regression was used for the development of a new equation for body fat percentage estimation in young adults (males). RESULTS: The group had mean age of 23.07 ± 7.55 years and height and weight with mean and standard deviation of 72.65 ± 10.40 kg, 1.74 ± 0.06 meters, respectively. Comparing the results between the US and SF, there was significant correlation for all points evaluated, with the thigh skinfold presenting the highest correlation, followed by the chest one. When the three methods are compared, the US presented better correlation with the BIA than with SF. A new equation for estimation of fat percentage by US can hence be proposed. CONCLUSIONS: It was noticed that in the studied population, US and BIA can estimate the body fat percentage with good correlations with the SF method.

A two-phase population study: relationships between overweight, body composition and risk of eating disorders Estudio a doble fase: relación entre el sobrepeso, la composición corporal y el riesgo de trastorno de la conducta alimentaria  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Overweight and eating disorder (ED are major public health problems in adolescents. Aims: To assess the association of overweight, body composition and anthropometric characteristics with the probability being at risk of ED. Methods: A two-phase study was used. 329 girls and 96 boys (aged 12-18 years from an initial sample of 2967 adolescents were studied. The BMI, percentage of fat mass estimated by bioimpedance (FM(BIA, waist circumference, waist-to-height ratio, and waist-to-hip ratio (WHipr were calculated. The Eating Attitudes Test, Youth's Inventory-4 and a questionnaire to evaluate social influences were administered. Results: A total of 34.7% of girls and 53.6% of boys at risk of ED were overweight (including obesity. For girls, overweight frequency was significantly higher in risk ED group than in control group. Increases of one point in the BMI or FM(BIA increased the probability of being at risk of ED by 12% (3.0-19.0 and 4% (0.0-8.0, respectively. An increase in Whipr was negatively associated with ED risk. Smoking and symptoms of dysthymia and the genralized anxiety disorder also increase the probability of being at risk of ED in adolescent girls. In adolescent boys, these relations were not observed. Conclusions: The higher BMI and the percentage of FM(BIA are associated with greater risk of ED in adolescent girls, when psychological factors are present. Increases in the WHipr, characteristic of childhood body is negatively associated with that risk.Introducción: El sobrepeso y los Trastornos de la Conducta Alimentaria (TCA son problemas importantes de salud pública entre los adolescentes.

Métodos: Se realizó un estudio con un diseño en doble fase. Se estudiaron 329 chicas y 96 chicos (de 12-18 años procedentes de una muestra inicial de 2967 adolescentes. Se calcularon el índice de masa corporal (IMC, el porcentaje de masa grasa (% MG(BIA, la circunferencia de la cintura, los cocientes cintura-talla y cintura-cadera. Se administraron el Eating Attitudes Test, el Youth's Inventory-4 y un cuestionario para evaluar influencia sociocultural. Resultados: El 34,7% de las chicas y el 53,6% de los chicos con riesgo de TCA presentan sobrepeso (incluyendo obesidad. La frecuencia de sobrepeso es significativamente más alta en las chicas del grupo de riesgo de TCA que las del grupo control. En las adolescentes, el aumento de un punto en el IMC o en el % MG(BIA incrementa el riesgo de estar en riesgo de TCA en 12% (3,0-19,0 y 4% (0,0-8,0, respectivamente; un incremento en el cociente cintura-cadera se asocia negativamente con el riesgo de TCA. Fumar, presentar síntomas de distimia y de trastornos de ansiedad generalizada también se asociaron con la probabilidad de estar en riesgo de TCA, en las adolescentes. En los varones, no se han observado esas relaciones. Conclusiones: El mayor IMC y de % MG(BIA se asocian con mayor riesgo de TCA en las adolescentes cuando los factores psicológicos están presentes. Un aumento en el cociente cintura-cadera, característico de un cuerpo infantil, se asocia negativamente con el riesgo de TCA.

The relationship between bioelectrical impedance phase angle and subjective global assessment in advanced colorectal cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Bioelectrical Impedance (BIA derived phase angle is increasingly being used as an objective indicator of nutritional status in advanced cancer. Subjective Global Assessment (SGA is a subjective method of nutritional status. The objective of this study was to investigate the association between BIA derived phase angle and SGA in advanced colorectal cancer. Methods We evaluated a case series of 73 stages III and IV colorectal cancer patients. Patients were classified as either well-nourished or malnourished using the SGA. BIA was conducted on all patients and phase angle was calculated. The correlation between phase angle and SGA was studied using Spearman correlation coefficient. Receiver Operating Characteristic curves were estimated using the non-parametric method to determine the optimal cut-off levels of phase angle. Results Well-nourished patients had a statistically significantly higher (p = 0.005 median phase angle score (6.12 as compared to those who were malnourished (5.18. The Spearman rank correlation coefficient between phase angle and SGA was found to be 0.33 (p = 0.004, suggesting better nutritional status with higher phase angle scores. A phase angle cut-off of 5.2 was 51.7% sensitive and 79.5% specific whereas a cut-off of 6.0 was 82.8% sensitive and 54.5% specific in detecting malnutrition. Interestingly, a phase angle cut-off of 5.9 demonstrated high diagnostic accuracy in males who had failed primary treatment for advanced colorectal cancer. Conclusion Our study suggests that bioimpedance phase angle is a potential nutritional indicator in advanced colorectal cancer. Further research is needed to elucidate the optimal cut-off levels of phase angle that can be incorporated into the oncology clinic for better nutritional evaluation and management.

Equity in the allocation of public sector financial resources in low- and middle-income countries: a systematic literature review.  

Science.gov (United States)

This review aims to identify, assess and analyse the evidence on equity in the distribution of public health sector expenditure in low- and middle-income countries. Four bibliographic databases and five websites were searched to identify quantitative studies examining equity in the distribution of public health funding in individual countries or groups of countries. Two different types of studies were identified: benefit incidence analysis (BIA) and resource allocation comparison (RAC) studies. Quality appraisal and data synthesis were tailored to each study type to reflect differences in the methods used and in the information provided. We identified 39 studies focusing on African, Asian and Latin American countries. Of these, 31 were BIA studies that described the distribution, typically across socio-economic status, of individual monetary benefit derived from service utilization. The remaining eight were RAC studies that compared the actual expenditure across geographic areas to an ideal need-based distribution. Overall, the quality of the evidence from both types of study was relatively weak. Looking across studies, the evidence confirms that resource allocation formulae can enhance equity in resource allocation across geographic areas and that the poor benefits proportionally more from primary health care than from hospital expenditure. The lack of information on the distribution of benefit from utilization in RAC studies and on the countries' approaches to resource allocation in BIA studies prevents further policy analysis. Additional research that relates the type of resource allocation mechanism to service provision and to the benefit distribution is required for a better understanding of equity-enhancing resource allocation policies.

Effect of the ethinylestradiol/norelgestromin contraceptive patch on body composition. Results of bioelectrical impedance analysis in a population of Italian women  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background As weight gain is one of the most frequently cited reasons for not using and for discontinuing hormonal contraceptives, in an open-label, single-arm, multicentre clinical study we evaluated the effect of the ethinylestradiol/norelgestromin contraceptive patch (EVRA, Janssen-Cilag International, Belgium on body composition using bioelectrical impedance analysis (BIA. Methods Body weight and impedance vector components (resistance (R and reactance (Xc, at 50 kHz frequency, Akern-RJL Systems analyzer were recorded before entry, after 1, 3 and 6 months in 182 Italian healthy women aged 29 yr (18 to 45, and with BMI 21.8 kg/m2 (16 to 31. Total body water (TBW was estimated with a BIA regression equation. Vector BIA was performed with the RXc mean graph method and the Hotelling's T2 test for paired and unpaired data. Results After 6 months body weight increased by 0.64 kg (1.1% and TBW increased by 0.51 L (1.7%. The pattern of impedance vector displacement indicated a small increase in soft tissue hydration (interstitial gel fluid. Body composition changes did not significantly differ among groups of previous contraceptive methods. Arterial blood pressure did not significantly change over time. Conclusion After 6 months of treatment with the ethinylestradiol/norelgestromin contraceptive patch we found a minimal, clinically not relevant, increase in body weight less than 1 kg that could be attributed to an adaptive interstitial gel hydration. This fluctuation is physiological as confirmed by the lack of any effect on blood pressure. This could be useful in increasing women's choice, acceptability and compliance of the ethinylestradiol/norelgestromin contraceptive patch.

Phase angle is a prognostic factor for survival in amyotrophic lateral sclerosis.  

Science.gov (United States)

Malnutrition is a well-known independent survival factor in ALS patients. Total body impedance analysis (BIA) has been validated for the measurement of fat-free mass. Another physical value obtained by BIA is phase angle (PA) that has been proposed to be an index of malnutrition or a survival prognostic factor in several diseases. We measured PA in a sample of 168 ALS patients and analysed the relationships between PA and neurological, respiratory and nutritional status, and determined whether PA is an independent prognostic factor for survival in ALS. BIA was performed using an Analycor3 instrument with surface electrodes at 50 kHz and 800 microA. PA was obtained using the formula: PA =arctan (Xc/R) (in degrees) where Xc is the body reactance and R the bioelectric resistance. Relationships between quantitative variables were assessed by linear correlation coefficients and through univariate and multivariate linear regression analyses. To assess the prognostic role of PA on survival of patients, we performed survival analyses based on the Kaplan-Meier method using the log rank test, and on univariate and multivariate Cox proportional hazard model. Baseline time was time from multidisciplinary visit (T1) to death or censoring time. PA was always significantly lower in ALS patients than in healthy control subjects published in the literature. PA was lower in our ALS malnourished patients than in non-malnourished patients (3.3+/-1.1 degrees versus 2.5+/-0.6 degrees , p =0.003). In multivariate linear regression analysis, manual muscle testing (pfree mass (pform, age and sex. Patients with a PA 2.5 degrees . We concluded that in ALS patients, PA is greatly decreased. It is related to the nutritional status of patients, and is also an independent prognostic factor of survival. PMID:18720089

Validity of dual X-ray absorptiometry scanning for determination of body composition in IDDM patients.  

DEFF Research Database (Denmark)

Data on body composition in patients with insulin-dependent diabetes mellitus (IDDM) are scarce. Dual X-ray absorptiometry (DXA) scanning has proved useful for this purpose in other groups of patients. We tested the validity of the DXA scanner for the determination of fat-free mass (FFM) and fat mass in IDDM patients and control subjects, as compared to other reference methods, i.e. total body potassium by 40K whole body counting (TBK), total body water by tritiated water (TBW), bioelectrical impedance analysis (BIA) and 24-h urinary creatinine excretion (Ucrea). A total of 13 healthy controls, 5 males and 8 females, aged 34.2 years +/- SD 10.4, and 11 IDDM patients, 5 males, 6 females, aged 28.1 years +/- 7.3, diabetes duration 4.2 +/- 2.9 (1.0-9.9), were examined. The patients had no long-term diabetic complications and they had normal ophthalmoscopy and urine albumin excretion. The agreement between FFM estimated by DXA and the other methods, expressed as mean difference +/- 2 SD was; for DXA vs. TBK, 0.09 +/- 6.26 and 0.50 +/- 5.26 kg for controls and IDDM patients respectively; DXA vs. TBW, -2.07 +/- 2.56 and -1.07 +/- 4.58 kg; DXA vs. Ucrea, -2.62 +/- 8.02 and 2.00 +/- 10.0 kg; DXA vs. BIA, -7.90 +/- 8.92 and -7.85 +/- 2.32 kg. The results obtained with BIA were significantly different from the other methods for both control subjects and IDDM patients. In conclusion, DXA scanning is a precise and valid method for estimation of fat-free mass in IDDM patients.

Contribution of DNA polymerase eta to immunoglobulin gene hypermutation in the mouse.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The mutation pattern of immunoglobulin genes was studied in mice deficient for DNA polymerase eta, a translesional polymerase whose inactivation is responsible for the xeroderma pigmentosum variant (XP-V) syndrome in humans. Mutations show an 85% G/C biased pattern, similar to that reported for XP-V patients. Breeding these mice with animals harboring the stop codon mutation of the 129/Olain background in their DNA polymerase iota gene did not alter this pattern further. Although this G/C bia...

Methods: in a cross-sectional analyses, body composition was measured by bioelectrical impedance analysis (BIA), skinfold thickness (SF) and dual-energy x-ray absorptiometry (DXA) in 10 subjects from HIV+LIPO+ group; 22 subjects from HIV+LIPO- group and 12 from Control group. Results: There were no differences in age and body mass index (BMI) between groups. The fat mass (FM) (%) estimated by SF did not correlate with DXA in HIV+LIPO+ group (r = 0,46/ p > 0,05) and had fair agreement in both HIV groups (HIV+LIPO+ =0,35/ HIV+ LIPO- = 0,40).

Charge and spin transport in spin valves with anisotropic spin relaxation  

CERN Document Server

We investigate effects of spin-orbit splitting on electronic transport in a spin valve consisting of a large quantum dot defined on a two-dimensional electron gas with two ferromagnetic contacts. In the presence of both structure inversion asymmetry (SIA) and bulk inversion asymmetry (BIA) a giant anisotropy in the spin-relaxation times has been predicted. We show how such an anisotropy affects the electronic transport properties such as the angular magnetoresistance and the spin-transfer torque. Counterintuitively, anisotropic spin-relaxation processes sometimes enhance the spin accumulation.

Fast simultaneous determination of BHA and TBHQ antioxidants in biodiesel by batch injection analysis using pulsed-amperometric detection.  

Science.gov (United States)

We report the first amperometric method for the simultaneous determination of butylated hydroxyanisole (BHA) and tert-butylhydroquinone (TBHQ) in biodiesel using batch-injection analysis (BIA) coupled to pulsed-amperometry. A sequence of potential pulses was selected in order to detect TBHQ and BHA separately in a single injection step at a glassy-carbon electrode. Samples were diluted in 50% v/v hydroethanolic solution with 0.1 mol L(-1) HClO(4) (supporting electrolyte) before injection using an electronic pipette. The method is highly precise (RSDTBHQ, respectively), and can be easily adapted for on-site determinations. PMID:22967589

What´s cheapest, intravenous iron sucrose- or intravenous iron carboxymaltose treatment in IBD patients? : It dependent on the economic evaluation perspective!  

DEFF Research Database (Denmark)

  What´s cheapest, intravenous iron sucrose- or intravenous iron carboxymaltose treatment in IBD patients? It dependent on the economic evaluation perspective!   Aim: To evaluate the health care cost for intravenous iron sucrose (Venofer®, Vifor) and intravenous iron carboxymaltose (Ferinject®, Vifor) treatment to IBD patients in an outpatient setting.   Background: Intravenous iron sucrose can be given as a maximum of 200 mg Fe++ per infusion vs. intravenous iron carboxymaltose that can be given as a maximum of 1000 mg Fe++ in a single infusion leading to fewer infusions and visits. The drug-cost per mg iron is for iron carboxymaltose approximately double the cost of iron sucrose.   Patients and Methods: Data related to 111 IBD-patients treated with intravenous iron at Aarhus University Hospital from August 2005 until October 2009 was used for the economic evaluation. Analysis included a Budget Impact Analysis (BIA) from a hospital perspective, a Cost Effective Analysis (CEA) from a patient perspective and a Cost Benefit Analysis (CBA) consecutively including 20 IBD patients' willingness-to-pay' (WTP) assessment. BIA and CEA analysis were based on total infusion-doses from 500 mg Fe++ till 1600 mg Fe++. The WTP analysis was based on a total infusion-dose at 1400 mg Fe++. The evaluations are analysed assuming that the effect parameter (quantity of iron delivered) is comparable regardless of the iron formulation given intravenously.   Results: The BIA including price for drug, utensils and ½ hour spend by a nurse per visit; showed approximately 150€ extra cost per 1000 mg Fe++ administrated, if iron carboxymaltose was chosen. In contrast the CEA including both BIA-values and patient-related costs (transportation and lost income) showed iron carboxymaltose to be more cost-effective than iron sucrose, due to fewer outpatient setting visits. As IBD-patients could have less income as the average of the background population due to disease activity, sensitivity analysis using a 50% income level weredone, showing the same tendency but less significant. The average patients WTP for a total of iron-dose was to 233€ to reduce the numbers of infusion from 7 till 2.    Conclusion: The cost of choosing iron carboxymaltose rather than iron sucrose in treatment of iron deficiency in IBD differs depending of the economic perspective chosen. Only the Budget Impact Analysis showed iron sucrose to be the cheapest. If the patients' perspective is included in the economic evaluation iron carboxymaltose is the most cost-effective.

The Biases of Optical Line-Ratio Selection for Active Galactic Nuclei, and the Intrinsic Relationship between Black Hole Accretion and Galaxy Star Formation  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We use 317,000 emission-line galaxies from the Sloan Digital Sky Survey to investigate line-ratio selection of active galactic nuclei (AGNs). In particular, we demonstrate that "star formation dilution" by HII regions causes a significant bias against AGN selection in low-mass, blue, star-forming, disk-dominated galaxies. This bias is responsible for the observed preference of AGNs among high-mass, green, moderately star-forming, bulge-dominated hosts. We account for the bia...

Asbestos in road surfaces. Forgotten or hidden?; Asbest in Strassenbelaegen. Vergessen oder verheimlicht?  

Energy Technology Data Exchange (ETDEWEB)

The problem of asbestos in road surfaces is handled differently in the individual Federal States of Germany. Currently, only in Lower Saxony and partly in Hamburg and Schleswig-Holstein the road surfaces were analysed according to the existence of asbestos with respect to the regulation TRGS 517/BIA 7487. The remaining Federal States assume fundamentally that asphalt may contain asbestos. Protective measures such as milling of road surfaces are applied. Te most Federal States do not supply information on the handling of TRGD 517 when building roads.

We classify up to conjugacy all subgroups of certain types in the full, affine and special affine Cremona groups and prove that the normalizers of these subgroups are algebraic. As an application, we obtain new results on the linearization problem by generalizing Bia?ynicki-Birula's results of 1966-67 to disconnected groups. We prove fusion theorems for n-dimensional tori in the affine and special affine Cremona groups of rank n, and introduce and discuss the notions of Jordan decomposition and torsion primes for the Cremona groups.

Development of a dispersively accurate conservative level set scheme for capturing interface in two-phase flows  

Science.gov (United States)

A two-step interface capturing scheme, implemented within the framework of conservative level set method, is developed in this study to simulate the gas/water two-phase fluid flow. In addition to solving the pure advection equation, which is used to advect the level set function for tracking interface, both nonlinear and stabilized features are taken into account for the level set function so that a sharply varying interface can be stably predicted. To preserve the conservative property, the mapping given by ??=x?-u?t is performed between two coordinates x? and ?? for the advection-diffusion equation in a flow field with velocity u. To capture the interface, the flux term capable of compressing the level set contours is also adopted in the construction of linear inviscid Burgers' equation, which is indispensable in the level set method. To resolve the physically sharp interface without incurring contact discontinuity oscillations, a damping term which is nonlinear in terms of the level set function and can render an adequate artificial diffusion to stabilize the contact surface is added into the reinitialization step in the modified level set method. For accurately predicting the level set function, the advection scheme for solving the linear inviscid Burgers' equation in the advection step of the modified level set method is developed to accommodate the true dispersion relation. The solution computed from the resulting two-dimensional dispersion-relation-preserving advection scheme can minimize the phase error. Less artificial damping is needed to damp the oscillations in the vicinity of contact surface and the interface can be less numerically smeared. For the sake of programming simplicity, the incompressible two-phase flow will be discretized in non-staggered grids without incurring checkerboard oscillations by the developed explicit compact scheme for the approximation of pressure gradient terms. For the verification of the proposed two-dimensional dispersion-relation-preserving scheme and the non-staggered incompressible flow solver, three benchmark problems have been chosen in this study. The proposed conservative level set method for capturing the interface in incompressible fluid flows is also verified by solving the dam-break, bubble rising in water, droplet falling in water and Rayleigh-Taylor instability problems. Good agreements with the referenced solutions are demonstrated for all the four investigated problems.

Impact of hemodialysis on dual X-ray absorptiometry, bioelectrical impedance measurements, and anthropometry  

DEFF Research Database (Denmark)

Dual X-ray absorptiometry (DXA) performs noninvasive assessment of bone and soft tissue with high precision. However, soft tissue algorithms assume that 73.2% of the lean body mass is water, a potential source of error in fluid retention. We evaluated DXA (model QDR-2000; Hologic Inc, Waltham, MA), bioelectrical impedance analysis (BIA), and simple anthropometry in 19 patients (9 women and 10 men, mean age 46 y) before and after hemodialysis, removing 0.9-4.3 L (x: 2.8L) of ultrafiltrate. The reduction in fat-free mass (FFM) measured by DXA was highly correlated with the ultrafiltrate, as determined by the reduction in gravimetric weight (r = 0.975, P <0.0001; SEE: 233 g), whereas BIA was considerably less accurate in assessing FFM reductions (r = 0.66, P <0.01; SEE: 757 g). Lumbar bone mineral density (BMD) was unaffected by dialysis, as were whole-body fat and BMD. Whole-body bone mineral content, however, was estimated to be 0.6% lower after dialysis. None of the simple anthropometric measurements correlated significantly with the reduction in FFM. In an unmodified clinical setting, DXA appears to be superior to other simple noninvasive methods for determining body composition, particularly when the emphasis is on repeated measurements.

Prediction of fat-free body mass from bioelectrical impedance and anthropometry among 3-year-old children using DXA  

DEFF Research Database (Denmark)

For 3-year-old children suitable methods to estimate body composition are sparse. We aimed to develop predictive equations for estimating fat-free mass (FFM) from bioelectrical impedance (BIA) and anthropometry using dual-energy X-ray absorptiometry (DXA) as reference method using data from 99 healthy 3-year-old Danish children. Predictive equations were derived from two multiple linear regression models, a comprehensive model (height(2)/resistance (RI), six anthropometric measurements) and a simple model (RI, height, weight). Their uncertainty was quantified by means of 10-fold cross-validation approach. Prediction error of FFM was 3.0% for both equations (root mean square error: 360 and 356 g, respectively). The derived equations produced BIA-based prediction of FFM and FM near DXA scan results. We suggest that the predictive equations can be applied in similar population samples aged 2-4 years. The derived equations may prove useful for studies linking body composition to early risk factors and early onsetof obesity.

Neutral sphingomyelinase 2 is a key factor for PorB-dependent invasion of Neisseria gonorrhoeae.  

Science.gov (United States)

Disseminated gonococcal infection (DGI) is a rare but serious complication caused by the spread of Neisseria gonorrhoeae in the human host. Gonococci associated with DGI mainly express the outer membrane protein PorBIA that binds to the scavenger receptor expressed on endothelial cells (SREC-I) and mediates bacterial uptake. We recently demonstrated that this interaction relies on intact membrane rafts that acquire SREC-I upon attachment of gonococci and initiates the signalling cascade that finally leads to the uptake of gonococci in epithelial cells. In this study, we analysed the role of sphingomyelinases and their breakdown product ceramide. Gonococcal infection induced increased levels of ceramide that was enriched at bacterial attachment sites. Interestingly, neutral but not acid sphingomyelinase was mandatory for PorBIA -mediated invasion into host cells. Neutral sphingomyelinase was required to recruit the PI3 kinase to caveolin and thereby activates the PI3 kinase-dependent downstream signalling leading to bacterial uptake. Thus, this study elucidates the initial signalling processes of bacterial invasion during DGI and demonstrates a novel role for neutral sphingomyelinase in the course of bacterial infections.

Estimation of total body water by bioelectrical impedance analysis  

International Nuclear Information System (INIS)

Total body water (TBW) measured by bioelectrical impedance analysis (BIA) was directly compared with deuterium-isotope dilution in a total of 58 subjects. First, sex-specific and group equations were developed by multiple regression analysis in (10 each) obese and nonobese men and women. Height/resistive impedance was the most significant variable used to predict deuterium-dilution space (D2O-TBW) and, combined with weight, yielded R = 0.99 and SE of estimate = 1.75 L. Equations predicted D2O-TBW equally well for obese and nonobese subjects. Second, the equations were prospectively tested in a heterogeneous group of 6 males and 12 females. Sex-specific equations predicted D2O-TBW with good correlation coefficients (0.96 and 0.93), total error (2.34 and 2.89 L), and a small difference between mean predicted and measured D2O-TBW (-1.4 +/- 2.05 and -0.48 +/- 2.83 L). BIA predicts D2O-TBW more accurately than weight, height, and/or age. A larger population is required to validate the applicability of our equations

Los resultados de los sistemas BIA fueron 7,4 ± 3 kg; 5,6 ± 2,2 kg; 5,7 ± 2,5 kg y 7,4 ± 3 kg para los aparatos Biospace Inbody 720, Tanita BC400, Tanita TBF521 y Omron BF300 respectivamente. En las mujeres los resultados fueron 10,4 ± 2,7 kg de masa grasa mediante el método antropométrico y 10,3 ± 2,9 kg; 11 ± 3,3 kg; 11,5 ± 3,0 kg; 10 ± 2,9 kg para los aparatos Biospace Inbody 720, Tanita BC400, Tanita TBF521 y Omron BF300 respectivamente. Conclusiones: En el grupo masculino la concordancia entre la antropometría y los aparatos BIA fue moderadabaja, en cambio en las mujeres se halló una buena concordancia entre las dos técnicas para la estimación de la grasa corporal cuando fueron utilizados los aparatos Biospace Inbody 720 y Tanita BC400. Abstract in english Objective: To assess the level of agreement between the anthropometrical method and several bioimpedance (BIA) devices to estimate the fat mass in a group of physically active young people. Subjects: 55 students of Physical Activity Sciences and Sports of the INEFC of Barcelona; 29 men (age: 24.7 ± [...] 4.7 years; BMI: 23.4 ± 1.8) and 26 women (age: 22.9 ± 3.5; BMI: 21.5 ± 1.9). All of them voluntarily gave their informed consent. Materials and method: Anthropometrical assessment was done according to the International Society for the Advancement Kinanthropometry (ISAK) protocol, the fat % was calculated by the Siri's equation and was compared with that obtained by 4 different BIA devices: Biospace Inbody 720, Tanita BC400, Tanita TBF-521, and Omron BF-300. To assess the level of agreement of the results, the interclass correlation coefficient and the Bland Aldman method were used. Results: The estimated fat mass, in men, by the anthropometrical method was 7 ± 2.2 kg. The results by the BIA systems were: 7.4 ± 3 kg; 5.6 ± 2.2 kg; 5.7 ± 2.5 kg, and 7.4 ± 3 kg for Biospace Inbody 720, Tanita BC400, Tanita TBF521, and Omron BF300, respectively. In women, the results were 10.4 ± 2.7 kg of fat mass by means of the anthropometrical method and 10.3 ± 2.9 kg, 11 ± 3.3 kg, 11.5 ± 3.0 kg, and 10 ± 2.9 kg for Biospace Inbody 720, Tanita BC400, Tanita TBF521, and Omron BF300, respectively. Conclusions: In the male group, the level of agreement between anthropometrics and BIA devices was moderate-poor, whereas in women there was a good correlation between both techniques for estimating the body fat when the Biospace Inbody 720 and Tanita BC400 devices were used.

Caucasian children's fat mass: routine anthropometry v. air-displacement plethysmography.  

Science.gov (United States)

The present paper will use fat mass percentage (FM%) obtained via BOD POD® air-displacement plethysmography (FMADP%) to examine the relative validity of (1) anthropometric measurements/indices and (2) of FM% assessed with equations (FMeq%) based on skinfold thickness and bioelectrical impedance (BIA). In 480 Belgian children (aged 5-11 years) weight, height, skinfold thickness (triceps and subscapular), body circumferences (mid-upper arm, waist and hip), foot-to-foot BIA (Tanita®) and FMADP% were measured. Anthropometric measurements and calculated indices were compared with FMADP%. Next, published equations were used to calculate FMeq% using impedance (equations of Tanita®, Tyrrell, Shaefer and Deurenberg) or skinfold thickness (equations of Slaughter, Goran, Dezenberg and Deurenberg). Both indices and equations performed better in girls than in boys. For both sexes, the sum of skinfold thicknesses resulted in the highest correlation with FMADP%, followed by triceps skinfold, arm fat area and subscapular skinfold. In general, comparing FMeq% with FMADP% indicated mostly an age and sex effect, and an increasing underestimation but less dispersion with increasing FM%. The Tanita® impedance equation and the Deurenberg skinfold equation performed the best, although none of the used equations were interchangeable with FMADP%. In conclusion, the sum of triceps and subscapular skinfold thickness is recommended as marker of FM% in the absence of specialised technologies. Nevertheless, the higher workload, cost and survey management of an immobile device like the BOD POD® remains justified. PMID:23057848

Formulación de una ecuación para predecir la masa grasa corporal a partir de bioimpedanciometría en adultos en un amplio rango de edad e índice de masa corporal Formulation of an equation to predict fat mass using bioelectrical impedance in adults in a wide range of ages and body mass index  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Bioelectrical impedance (BIA has a good correlation and agreement with reference techniques, such as dual energy X-ray absorptiometry (DEXA, to assess body composition. Aim: To develop and assess the concordance of an equation to predict body fat mass derived from anthropometric data, gender, age and resistance obtained from bioelectrical impedance in adults, using DEXA as the reference method. Patients and Methods: Cross-sectional study of 62 women and 59 men aged 18 to 64 years with a body mass index ranging from 18.5 to 34.8 kg/ m². The equation was constructed using a predictive statistical model, considering sex, age, weight, resistance index (height²(cm/ resistance (ohms, as independent variables, and fat mass as the dependent variable. Results: The R² of the regression model was 0.96, and the standard error of estimation was 2.58 kg (p 0.05 and - 4.5 ± 8,9% (p < 0.05 in both genders and in women, respectively. Conclusions: The concordance between estimation of fat mass by the formula developed in this work and by DEXA was better than the estimation obtained using the formula proposed by the manufacturer of the BIA equipment.

Screening for sarcopenia in obesity  

Science.gov (United States)

Sarcopenia is a progressive and generalized loss of skeletal muscle mass (SM) and function which can also be found in obese adults. The aim of the study was to evaluate the prevalence of sarcopenia in 1 245 obese women (18 - 67 years, weight 114.7±24.5 kg; BMI 44.1±9.2 fat mass 49.0±6.2%) from Southern Italy. Body composition was evaluated by bioimpedance analysis (BIA) and SM calculated by using Janssen's equation; therefore the sex-specific cut-off points of percentage skeletal muscle index were used. The whole population was divided in two age groups: A (18-40 years; n. 808; weight 115.4±23.5 kg; BMI 43.8±8.8 kg/m2) and B (41-67 years; n. 438; weight 113.4±26.3 kg; BMI 44.8±9.9 kg/m2). In all the sample there was 2.7% moderate and 0.6% severe sarcopenia; in group A, 1.9% moderate and 0.6% severe sarcopenia whilst in group B 4.3% moderate and 0.7% severe sarcopenia. The results of our study suggest that, based on a screening examination by BIA, moderate/severe sarcopenia can be detected in an unselected middle-aged obese population. Further studies are required to clarify the diagnosis with functional tests.

Relationship Between History of Smoking, Metabolic and Inflammatory Markers, Parameters of Body Composition and Muscle Strength.  

Science.gov (United States)

The objective of this study was to investigate the relationship between smoking history expressed by pack-years, metabolic and inflammatory markers, parameters of body composition (BC) and muscle strength among heavy smokers. A detailed smoking history was obtained from 49 heavy smokers (age?=?44?±?12, pack-years?=?31?±?23). Blood samples were analyzed for levels of glucose, lipids, liver enzymes and C-reactive protein (CRP). Anthropometric measurements included waist circumference and assessment of BC by dual energy X-ray absorptiometry (DEXA) and bioelectrical impedance analysis (BIA). Muscle strength was assessed by handgrip dynamometry and predicted one-repetition maximum (p1RM) tests. We found positive correlations between pack-years of smoking, fasting glucose, alkaline phosphatase and CRP levels. Pack-years were also positively correlated with waist circumference, body mass index (BMI), whole-body and trunk fat mass measured by both DEXA and BIA. Negative correlation was found between pack-years of smoking and muscle strength measured by p1RM for the leg press exercise. After adjustment for age, sex and BMI, a positive correlation remained between pack-years of smoking and CRP levels. We conclude that after controlling for possible confounders, smoking history was found to be positively associated with CRP levels among heavy smokers. PMID:25468009

Total mercury of selected fish species from Laguna de Bay  

International Nuclear Information System (INIS)

Dalag Ophicephalus striatus Block, kanduli Arius thalassinus Ruppell, bia Amblygobius phalaena Cuvier et Valenciennes and tilapia Tilapia nilotica Linnnaeus collected from Laguna de Bay between Taguig and Binangonan area in August 1989 to July 1990 were analyzed for total mercury by atomic absorption spectrometry. The highest metal concentration in soft muscle tissue was observed in Dalag followed by kanduli, less in bia and least in tilapia with mean values of 0.021, 0.020, 0.013, and 0.008 ug/g, respectively. Analysis using two-way ANOVA showed a significant difference in the mean total mercury in ug/g in the difference fish samples, among the different months and the interaction between these two variables. Mean total mercury of the four fish samples were significantly higher in April than in October. The results show that the levels of total mercury in the fish samples are below the World Health Organization maximum tolerable consumption of mercury in food of 300 ug or 0.03 mg of total mercury per week.

Measuring obesity: results are poles apart obtained by BMI and bio-electrical impedance analysis  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To analyse the use of BMI and bioelectrical impedance analysis (BIA in assessment of adiposity among young and elderly population. Materials and methods: Age, height, weight and percent body fat (PBF of 101 young and 276 elder subjects were recorded. PBF was measured directly by BIA instrument (PBFb and also calculated from BMI (PBFf. The classification of subjects into underweight, normal, overweight and obese was based on the age- and sex-specific BMI cutoff values and PBFb following standard guidelines. Results: The calculated mean BMI values of young and old age groups were statistically same. PBF was significantly high in elder subjects. There was no statistical difference in mean PBFb and PBFf in young subjects but the difference was significant in elder subjects. The PBFf values were highly correlated (r: 0.92 to 0.96 with PBFb values in young age groups unlike elder groups of both males and females. PBFb based categorization of subjects’ presented totally different scenario compared to results obtained by BMI analysis to assess adiposity. Conclusion: The cases such as increasing fatness with aging even when BMI remains constant, the causes of country or ethnic differences in BMI analysis, poor correlation in PBFb and PBFf values in elder age group emphasize on the limitations of BMI based analysis. PBFb within limitations seems to be an improved phenotypic characteristic over BMI.

A study of percentage body fat in children via dual energy X-ray absorptiometry (DEXA)  

International Nuclear Information System (INIS)

Percentage body fat was measured using dual energy X-ray absorptiometry (DEXA), bioelectrical impedance analysis (BIA) and skin fold calipers on 26 children (nine in obesity group, 12 in healthy group and 5 in steroid treated group). Mean percent body fat did not differ significantly between methods in the whole subjects as well as the healthy group and the steroid treated group. However, the mean percent body fat using skin fold caliper was higher for the obesity group than the other two. The measurements of all cases in the obesity group by DEXA were higher than those of BIA. There were high correlations among the percent body fat obtained by each technique. According to the analysis of mean regional percent fat, the percent fat of legs was the highest in the healthy and steroid treated group, while there was no regional difference in the obesity group. It should be possible to classify each case in the obesity group into upper segment and lower segment obesity by DEXA. (author)

Propofol Infusion Associated Metabolic Acidosis in Patients Undergoing Neurosurgical Anesthesia: A Retrospective Study  

Science.gov (United States)

Objective Propofol and volatile anesthesia have been associated with metabolic acidosis induced by increased lactate. This study was designed to evaluate changes in pH, base excess (BE), and lactate in response to different anesthetic agents and to characterize propofol infusion-associated lactic acidosis. Methods The medical records of patients undergoing neurosurgical anesthesia between January 2005 and September 2012 were examined. Patients were divided into 2 groups : those who received propofol (total intravenous anesthesia, TIVA) and those who received sevoflurane (balanced inhalation anesthesia, BIA) anesthesia. Propensity analysis was performed (1 : 1 match, n=47), and the characteristics of the patients who developed severe acidosis were recorded. Results In the matched TIVA and BIA groups, the incidence of metabolic acidosis (11% vs. 13%, p=1) and base excess (p>0.05) were similar. All patients in the TIVA group who developed severe acidosis did so within 4 hours of the initiation of propofol infusion, and these patients improved when propofol was discontinued. Conclusions The incidence of metabolic acidosis was similar during neurosurgical anesthesia with propofol or sevoflurane. In addition, severe acidosis associated with propofol infusion appears to be reversible when propofol is discontinued. PMID:25328651

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese INSTRODUÇÃO: O balão intra-aórtico (BIA) é utilizado há décadas como dispositivo de assistência circulatória, sendo recomendado na maioria das diretrizes, apesar da fraca evidência em relação à redução da mortalidade. O objetivo deste estudo foi avaliar o uso do BIA como ferramenta adjunta na interv [...] enção coronária percutânea (ICP). MÉTODOS: Registro unicêntrico que analisou a evolução hospitalar de 134 pacientes consecutivos que utilizaram BIA durante ICP de alto risco ou na vigência de choque cardiogênico. RESULTADOS: A média de idade foi de 64,7 + 12,5 anos e 67,9% eram do sexo masculino. A população apresentou características de alto risco, com 33,5% de diabéticos, 73,1% tratados na vigência de infarto do miocárdio, 68,6% com padrão triarterial, e fração de ejeção do ventrículo esquerdo de 38,6 + 16,1%. Fluxo TIMI 2/3 foi obtido em 86,4% dos casos, sendo tratada 1,6 + 0,6 lesão/paciente. Ocorreram 18 (13,4%) reinfartos, dos quais 9 (6,7%) por trombose do stent, sendo 2 (1,4%) pacientes encaminhados para cirurgia de revascularização miocárdica e 16 (11,9%), para nova ICP. A mortalidade hospitalar foi de 61,2% e a taxa de eventos cardíacos adversos maiores (ECAM) foi de 67,2%. Por análise multivariada, foram preditores de mortalidade: idade > 65 anos, ICP prévia, necessidade de diálise e padrão triarterial. Os preditores de sobrevida foram: função ventricular normal, fluxo TIMI 2/3 ao final do procedimento e permanência do BIA > 72 horas. CONCLUSÕES: Os pacientes que utilizaram BIA durante ICP apresentaram perfil clínico de risco muito alto, que se refletiu em elevada taxa de óbito. Fatores clínicos, angiográficos e do procedimento podem identificar variáveis que interferem independentemente na mortalidade. Abstract in english BACKGROUND: The intra-aortic balloon pump (IABP) has been used for decades as a circulatory support device, being recommended in most guidelines, despite poor evidence of mortality reduction. The purpose of this study was to evaluate the use of IABP as an adjunct therapy in percutaneous coronary int [...] ervention (PCI). METHODS: Single center registry analyzing in-hospital outcomes of 134 consecutive patients submitted to IABP during high risk PCI or in the presence of cardiogenic shock. RESULTS: Mean age was 64.7 + 12.5 years and 67.9% were males. The population presented high-risk features, with 33.5% of diabetic patients, 73.1% treated in the presence of myocardial infarction, 68.6% with three-vessel disease and left ventricular ejection fraction of 38.6 + 16.1%. TIMI 2/3 flow was obtained in 86.4% of the cases and 1.6 + 0.6 lesion/patient was treated. There were 18 (13.4%) reinfarctions, of which 9 (6.7%) were due to stent thrombosis, 2 (1.4%) patients were referred for CABG and 16 (11.9%) for a new PCI. Hospital mortality was 61.2% and the major adverse cardiac events (MACE) rate was 67.2%. By multivariate analysis, predictors of mortality were: age > 65 years, prior PCI, need of dialysis and three-vessel disease. Predictors of survival were: normal ventricular function, TIMI 2/3 flow at the end of the procedure and IABP utilization > 72 hours. CONCLUSIONS: Patients undergoing PCI with IABP support have a very high risk clinical profile, which led to high mortality rates. Clinical, angiographic and procedure-related factors can identify independent variables for mortality.

Apesar disto, têm sido descritas algumas complicações relacionadas à sua inserção, duração do uso e localização. O objetivo deste estudo foi investigar retrospectivamente a oc [...] orrência de infecções em pacientes críticos que necessitaram do uso do balão intra-aórtico (BIA) após operação cardíaca. Entre janeiro de 1990 e julho de 1992, foram revisados os prontuários de 97 pacientes que necessitaram de BIA no pós-operatório de operação cardíaca, sendo que apenas 55 apresentavam informações completas que permitiram sua inclusão na revisão. Foram obtidas informações a respeito de ocorrência de infecções, resultados de culturas, tipo e tempo de duração das operações, tempo de circulação extracorpórea, duração da cateterização intravascular e evolução clínica. Foram considerados os seguintes locais de infecção: pulmão, urina, corrente sangüínea, ferida operatória e local de inserção do BIA. A média de permanência do BIA foi de 3,9 ± 2,01 dias e os tempos médios de operação e de circulação extracorpórea foram 8h e 2,5h, respectivamente. Observamos uma alta incidência de infecções nestes pacientes, principalmente pneumonia (63,6%). A taxa de infecção no local de inserção do BIA foi de 7% e maior que a taxa geral de infecção da ferida operatória em nossa Instituição (3%). Apesar desta alta incidência de infecções não relacionar-se diretamente com a taxa de mortalidade, sugerimos rigorosa vigilância com relação à ocorrência de infecções e possíveis medidas profiláticas em relação a infecções pulmonares Abstract in english The technological advances of recent years have permitted a wide range of uses for intraaort balloon pumping (IABP) to support acute cardiac failure in many clinical condition. In spite of this, some complications related to its insertion, duration of use and location have been described. The aim of [...] his study was to investigate the incidence of infections in severely compromised postoperative cardiac patients undergoing IABP therapy. Between January 1990 and July 1992, the records of 97 patients that required IABP support after cardiac surgery were reviewed, but only 55 met the criteria to be included. The analysis consited of: incidence of infections, culture results, type and duration of by-pass and surgery duration of intravascular catheterization and clinical outcome. The following sites of infection were considered: lung, urine, blood, surgical incision and IABP catheter insertion. The mean time of procedures were: IABP= 3.9 ± 2.01 days surgery an by-pass equal to 8.0 and 2.5 hours respectively. We observed a high incidence of infection in these patients, mainly pneumonia (63.6%). The IABP insertion infection rate was 7.0% higher than our general postoperative wound infection rate (3.0%). Although this relatively higher incidence of infection may not directly relate to the martality rate, we suggest that these patients must have extremely careful surveillance for ocurrence of infections and possible prophylactic measures regarding pulmonary infections.

Contrapulsação em operação cardíaca: análise retrospectiva da incidência de infecção Intra-aortic balloon pumping: incidense of complications related to its insertion  

Directory of Open Access Journals (Sweden)

Full Text Available Recentes avanços tecnológicos ampliaram o uso do balão intra-aórtico como medida de suporte na insuficiência cardíaca aguda. Apesar disto, têm sido descritas algumas complicações relacionadas à sua inserção, duração do uso e localização. O objetivo deste estudo foi investigar retrospectivamente a ocorrência de infecções em pacientes críticos que necessitaram do uso do balão intra-aórtico (BIA após operação cardíaca. Entre janeiro de 1990 e julho de 1992, foram revisados os prontuários de 97 pacientes que necessitaram de BIA no pós-operatório de operação cardíaca, sendo que apenas 55 apresentavam informações completas que permitiram sua inclusão na revisão. Foram obtidas informações a respeito de ocorrência de infecções, resultados de culturas, tipo e tempo de duração das operações, tempo de circulação extracorpórea, duração da cateterização intravascular e evolução clínica. Foram considerados os seguintes locais de infecção: pulmão, urina, corrente sangüínea, ferida operatória e local de inserção do BIA. A média de permanência do BIA foi de 3,9 ± 2,01 dias e os tempos médios de operação e de circulação extracorpórea foram 8h e 2,5h, respectivamente. Observamos uma alta incidência de infecções nestes pacientes, principalmente pneumonia (63,6%. A taxa de infecção no local de inserção do BIA foi de 7% e maior que a taxa geral de infecção da ferida operatória em nossa Instituição (3%. Apesar desta alta incidência de infecções não relacionar-se diretamente com a taxa de mortalidade, sugerimos rigorosa vigilância com relação à ocorrência de infecções e possíveis medidas profiláticas em relação a infecções pulmonaresThe technological advances of recent years have permitted a wide range of uses for intraaort balloon pumping (IABP to support acute cardiac failure in many clinical condition. In spite of this, some complications related to its insertion, duration of use and location have been described. The aim of his study was to investigate the incidence of infections in severely compromised postoperative cardiac patients undergoing IABP therapy. Between January 1990 and July 1992, the records of 97 patients that required IABP support after cardiac surgery were reviewed, but only 55 met the criteria to be included. The analysis consited of: incidence of infections, culture results, type and duration of by-pass and surgery duration of intravascular catheterization and clinical outcome. The following sites of infection were considered: lung, urine, blood, surgical incision and IABP catheter insertion. The mean time of procedures were: IABP= 3.9 ± 2.01 days surgery an by-pass equal to 8.0 and 2.5 hours respectively. We observed a high incidence of infection in these patients, mainly pneumonia (63.6%. The IABP insertion infection rate was 7.0% higher than our general postoperative wound infection rate (3.0%. Although this relatively higher incidence of infection may not directly relate to the martality rate, we suggest that these patients must have extremely careful surveillance for ocurrence of infections and possible prophylactic measures regarding pulmonary infections.

Impact of Atmospheric Attenuations Time Resolutions in Solar Radiation Derived from Satellite Imagery  

Science.gov (United States)

Accurate knowledge of solar irradiance components at the earth surface is of highly interest in many scientific and technology branches concerning meteorology, climate, agriculture and solar energy applications. In the specific case of solar energy systems the solar resource analysis with accuracy is a first step in every project since it is a required data for design, power output estimations, systems simulations and risk assessments. Solar radiation measurement availability is increasing both in spatial density and in historical archiving. However, it is still quite limited and most of the situations cannot make use of a long term ground database of high quality since solar irradiance is not generally measured where users need data. Satellite-derived solar radiation estimations are a powerful and valuable tool for solar resource assessment studies that have achieved a relatively high maturity due to years of developments and improvements. However, several sources of uncertainty are still present in satellite-derived methods. In particular, the strong influence of atmospheric attenuation information as input to the method is one of the main topics of improvement. Since solar radiation attenuation by atmospheric aerosols, and water vapor in a second place, is, after clouds, the second most important factor determining solar radiation, and particularly direct normal irradiance, the accurate knowledge of aerosol optical depth and water vapor content is relevant in the final output of satellite-derived methods. This present work, two different datasets we are used for extract atmospheric attenuation information. On the one hand the monthly mean values of the Linke turbidity factor from Meteotest database, which are twelve unique values of the Linke turbidity worldwide with a spatial resolution of 1/12º. On the other hand, daily values of AOD (Aerosol Optical Depth) at 550 nm, Angstrom alpha exponent and water vapor column were taken from a gridded database that combines MODIS Terra satellite and Aqua, C005 data collection. The AOD at 550 nm in the C005 collection data of MODIS have been proven to be more accurate than the previous version in assessment studies using AERONET data. The need of daily information of aerosol attenuation parameters has been clearly observed in places where aerosol optical depth variability is high (as the case of India). In addition, the sensitivity to the clear sky model used in the methodology has been also briefly analyzed, but a deeper analysis would require more extensive ground measurement. The sensitivity results show that, as expected, DNI estimations are much more sensible to the atmospheric attenuation input than GHI. The GHI response to the atmospheric aerosol loading is modulated by the positive feedback of the diffuse component and by the angular projection. When comparing the sensitivity of satellite estimations in Spain and India, it is pointed out than the higher aerosol loading and dynamics that normally occurs over India cause higher variability of both GHI and DNI satellite calculations.

Changes in body fluid and energy compartments during prolonged hunger strike / Alterações nos compartimentos hídricos e energéticos do organismo durante a greve de fome  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese A privação total e prolongada de alimentos em adultos não-obesos é raramente vista, e poucos estudos documentaram as modificações da composição corpórea neste contexto.Num grupo de oito casos de greve de fome durante 43 dias, procedeu-se à estimativa dos compartimentos hídricos e energéticos, visand [...] o averiguar a influência sobre os mesmos da desnutrição progressiva.Os métodos incluiram índice de massa corporal (IMC), prega cutânea do tríceps (PCT), circunferência muscular do braço, e determinação através da bioimpedância (BIA) da água, massa gorda, massa magra e resistência corpórea total..A calorimetria indireta foi realizada em uma ocasião apenas.A idade do grupo era de 43,3± 6,2 anos (sete homens, uma mulher), somente água e ocasionais eletrólitos e vitaminas foram ingeridos no jejum, e a perda de peso média foi de 17,9%. Por volta do 43º dia da greve iniciou-se a reposição venosa rápida de fluidos, vitaminas e eletrólitos,antes de se prosseguir com a realimentação.A gordura corporal diminuiu em aproximadamente 60% (BIA e PCT), ao passo que o IMC caiu apenas 18%.A estimativa da gordura total inicial por BIA foi de 52,2± 5,4% do peso corporal, e mesmo no 43º dia do evento o valor calculado era de 19,7± 3,8% do peso.Os valores correspondentes deduzidos da PCT mostraram-se substancialmente inferiores, e mais compatíveis com os demais índices antropométricos. A água corporal revelou-se inicialmente contraída, com resistência elevada,sendo que estes achados se reverteram rapidamente por ocasião da hidratação venosa rápida.Quando do término da greve de fome o IMC (21,5± 2,6 kg/m²) e outras variáveis antropométricas revelavam-se numericamente aceitáveis, sugerindo eficiente conservação de musculatura e energia na fase de dieta zero.Conclui-se que: 1) Todos os compartimentos orgânicos se contrairam na greve de fome, porém o tecido adiposo foi de longe o mais afetado; 2) A água corporal mostrou-se reduzida com elevada resistência total, mas estes achados inverteram-se prontamente mediante hidratação parenteral; 3) O encontro de gordura total excessiva e de aumento da massa magra com o avançar do jejum sugerem que as leituras de BIA são inapropriadas para esta população e fornecem resultados incoerentes; 4) Com base nos parâmetros expostos os doentes não estavam morfologicamente desnutridos ao cabo de 43 dias, todavia não foram aqui avaliados outros transtornos de considerável importância prognóstica.

Measurements included body mass index (BMI), triceps skinfold (TSF), arm muscle circumference (AMC), and bioimpedance (BIA) determinations of water, fat, lean body mass (LBM), and total resistance. Indirect calorimetry was also performed in one occasion. The age of the group was 43.3±6.2 years (seven males, one female). Only water, intermittent vitamins and electrolytes were ingested, and average weight loss reached 17.9%. On the last two days of the fast (43rd-44th day) rapid intravenous fluid, electrolyte, and vitamin replenishment were provided before proceeding with realimentation. Body fat decreased approximately 60% (BIA and TSF), whereas BMI reduced only 18%. Initial fat was estimated by BIA as 52.2±5.4% of body weight, and even on the 43rd day it was still measured as 19.7±3.8% of weight. TSF findings were much lower and commensurate with other anthropometric results. Water was comparatively low with high total resistance, and these findings rapidly reversed upon the intravenous rapid hydration. At the end of the starvation period, BMI (21.5±2.6 kg/m²) and most anthropometric determinations were still acceptable, suggesting effi

Spark ignition vehicle contributions to atmospheric fine elemental carbon concentrations in coastal, rural and urban communities using polycyclic aromatic hydrocarbon tracers in the CMB model modified for reactivity  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Repartimos a parcela do componente de carbono elementar (CE) em PM2,5 atmosférico atribuível à emissões de veículos com ignição por faísca (SI) em amostras coletadas durante dois anos em doze comunidades no Sul da Califórnia, incluindo zonas costeiras, rurais e urbanas usando o Modelo de Balanço de [...] Massa Química (CMB8) modificado para levar em conta a reatividade dos hidrocarbonetos policíclicos aromáticos (HPAs). Foram avaliadas as razões HPA/CE em amostras coletadas no túnel Caldecott para utilização como assinaturas das fontes. A reatividade dos HPAs que ocorre durante o transporte de aerossóis atmosféricos que pode afetar as estimativas de contribuição das fontes (ECF) durante o verão/primavera/outono foi considerada com o uso de constantes de decaimento medidas experimentalmente. Nossos resultados mostram que o benzo[ghi]perylene e o indeno[1,2,3-cd]pireno podem ser utilizados com sucesso como marcadores específicos de CE nas emissões por veículos com SI. A estimativa média da porção de CE atribuído pelo modelo à emissões provenientes de SI nessas comunidades foi de 39, 58 e 62%, respectivamente, durante o verão, primavera/outono, e inverno. Para todas as comunidades costeiras, as atribuições a veículos por SI representam cerca do dobro das estimativas para as áreas rurais e urbanas, antes de dezembro 2003 quando MTBE ainda era usado na California. Abstract in english We apportioned the elemental carbon (EC) component of ambient PM2.5 attributable to emissions from spark ignition (SI) vehicles in samples collected over a three-year period in twelve Southern California communities, including coastal, rural, and urban areas using the chemical mass balance model (CM [...] B8) modified for polycyclic aromatic hydrocarbon (PAH) reactivity. Selected PAH/EC ratios, measured in samples collected in the Caldecott tunnel were evaluated for use as fingerprints. PAH reactivity which occurs during atmospheric transport and affects the source contribution estimates during the summer/fall/spring months was accounted for using experimentally measured decay constants. Results showed that benzo[ghi]perylene and indeno[1,2,3-cd]pyrene can be used successfully as specific tracers of EC contributions from SI vehicles. The average EC portion of PM2.5 attributed by the model to SI emissions at these communities was 39, 58 and 62%, respectively, during the summer, spring/autumn, and winter. For all seasons, coastal community contributions represent about twice those found in the rural and urban inland communities, before December 2003 when MTBE was still in use in California.

Air Temperature estimation from Land Surface temperature and solar Radiation parameters  

Science.gov (United States)

Air Temperature (AirT) is a fundamental parameter in a wide range of applications such as climate change studies, weather forecast, energy balance modeling, efficiency of Photovoltaic (PV) solar cells, etc. Air temperature data are generally obtained through regular measurements from meteorological stations. The distribution of these stations is normally sparse, so the spatial pattern of this parameter cannot be accurately estimated by interpolation methods. This work investigated the relationship between Air Temperature measured at meteorological stations and spatially contiguous measurements derived from Remote Sensing techniques, such as Land Surface Temperature (LST) maps, emissivity maps and shortwave radiation maps with the aim of creating a continuous map of AirT. For LST and emissivity, MSG-SEVIRI LST product from Land Surface Analysis Satellite Applications Facility (LSA-SAF) has been used. For shortwave radiation maps, an Artificial Neural Networks ensemble model has been developed and previously tested to create continuous maps from Global Horizontal Irradiance (GHI) point measurements, utilizing six thermal channels of MSG-SEVIRI. The testing sites corresponded to three meteorological stations located in the United Arab Emirates (UAE), where in situ measurements of Air Temperature were available. From the starting parameters, energy fluxes and net radiation have been calculated, in order to have information on the incoming and outgoing long-wave radiation and the incoming short-wave radiation. The preliminary analysis (day and Night measurements, cloud free) showed a strong negative correlation (0.92) between Outgoing long-wave radiation - GHI and LST- AirT, with a RMSE of 1.84 K in the AirT estimation from the initial parameters. Regression coefficients have been determined and tested on all the ground stations. The analysis also demonstrated the predominant impact of the incoming short-wave radiation in the AirT hourly variation, while the incoming long-wave radiation remains almost constant during the testing period. To conclude, the final AirT maps have been used to calculate continuous maps of Net Radiation, showing an important application of the output of this work for surface energy balance retrieval.

Assessment of the Level-3 MODIS daily aerosol optical depth in the context of surface solar radiation and numerical weather modeling  

Directory of Open Access Journals (Sweden)

Full Text Available The Level-3 MODIS aerosol optical depth (AOD product offers interesting features for surface solar radiation and numerical weather modeling applications. Remarkably, the Collection 5.1 dataset extends over more than a decade, and provides daily values of AOD over a global regular grid of 1°×1° spatial resolution. However, most of the validation efforts so far have focused on Level-2 products (10-km, at original resolution and only rarely on Level-3 (at aggregated spatial resolution of 1°×1°. In this contribution, we compare the Level-3 Collection 5.1 MODIS AOD dataset available since 2000 against observed daily AOD values at 550 nm from more than 500 AERONET ground stations around the globe. One aim of this study is to check the advisability of this MODIS dataset for surface shortwave solar radiation calculations using numerical weather models. Overall, the mean error of the dataset is 0.03 (17%, relative to the mean ground-observed AOD, with a root mean square error of 0.14 (73%, relative to the same, albeit these values are found highly dependent on geographical region. For AOD values below about 0.3 the expected error is found very similar to that of the Level-2 product. However, for larger AOD values, higher errors are found. Consequently, we propose new functions for the expected error of the Level-3 AOD, as well as for both its mean error and its standard deviation. Additionally, we investigate the role of pixel count vis-à-vis the reliability of the AOD estimates. Our results show that a higher pixel count does not necessarily turn into a more reliable AOD estimate. Therefore, we recommend to verify this assumption in the dataset at hand if the pixel count is meant to be used. We also explore to what extent the spatial aggregation from Level-2 to Level-3 influences the total uncertainty in the Level-3 AOD. In particular, we found that, roughly, half of the error might be attributable to Level-3 AOD sub-pixel variability. Finally, we use a~radiative transfer model to investigate how the Level-3 AOD uncertainty propagates into the calculated direct normal (DNI and global horizontal (GHI irradiances. Overall, results indicate that, for Level-3 AODs smaller than 0.5, the induced uncertainty in DNI due to the AOD uncertainty alone is below 15% on average, and below 5% for GHI (for a solar zenith angle of 30°. However, the uncertainty in AOD is highly spatially variable, and so is that in irradiance.

What contributes to the combined effect of a complex mixture?  

Science.gov (United States)

The effect of a mixture of 10 compounds, which have previously been identified in an effect-directed analysis as potentially relevant for a specific contaminated riverine sediment (Brack et al. Arch. Environ. Contam. Toxicol. 1999, 37, 164), were investigated for the underlying joint effect. Components identified in an organic sediment extract included several PAHs (benzo[ghi]fluoranthene, benz[a]anthracene, fluoranthene, pyrene, 2-phenylnaphthalene, anthracene, and phenanthrene) plus prometryn, N-phenyl-2-naphthylamine, and parathion-methyl. Experiments were performed using a one-generation algal bioassay with the unicellular green algae Scenedesmus vacuolatus as well as chlorophyll fluorescence quenching analysis to describe the effects of the components and mixtures thereof. Analysis of the mixture effects based on concentration-response modeling of the effect data reveals that indeed effect contributions of several components can be expected although the mixture ratio is not equitoxic and the individual components vary greatly with respect to biological effect. Comparing predicted and observed mixture effects, the combined effect may not be attributed to a joint narcotic effect of the mixture components. Evidently, some of the components act specifically and dissimilar and may therefore be best described in their combined effect by response addition while for others a similar mode of action seems plausible. Chlorophyll fluorescence quenching analysis supports to discriminate between prometryn, N-phenyl-2-naphthylamine, and PAHs. A joint model for calculating the combined effect using concentration addition for the suspected unspecifically acting components in algae (PAHs and parathion-methyl) and subsequently response addition for this group and the other components clearly
