    Abstract The +1169A allele of the A/T single nucleotide polymorphism (SNP; rs2665802), located within intron 4 of the human growth hormone I (GHI) gene, has been associated with reduced levels of circulating GH and insulin-like growth factor I, a reduced risk of colorectal cancer and a predisposition to osteoporosis.

    There is limited and sometimes contradictory information about the genotoxicity of the polycyclic aromatic hydrocarbon benzo[ghi]perylene (B[ghi]P). Using recently developed metabolic toxicity screening arrays and a biocolloid reactor-LC-MS/MS approach, both featuring films of DNA and human metabolic enzymes, we demonstrated the relatively low reactivity of metabolically activated B[ghi]P toward DNA. Electro-optical toxicity screening arrays showed that B[ghi]P metabolites damage DNA at a 3-fold lower rate than benzo[a]pyrene (B[a]P), whose metabolites have a strong and well-understood propensity for DNA damage. Metabolic studies using magnetic bead biocolloid reactors coated with microsomal enzymes in 96-well plates showed that cyt P450s 1A1 and 1B1 provide high activity for B[ghi]P and B[a]P conversion. Consistent with published results, the major metabolism of B[ghi]P involved oxidations at 3,4 and 11,12 positions, leading to the formation of B[ghi]P 3,4-oxide and B[ghi]P 3,4,11,12-bisoxide. B[ghi]P 3,4-oxide was synthesized and reacted with deoxyadenosine at N6 and N7 positions and with deoxyguanosine at the N2 position. B[ghi]P 3,4-oxide is hydrolytically unstable and transforms into the 3,4-diol or converts to 3- or 4-hydroxy B[ghi]P. LC-MS/MS of reaction products from the magnetic biocolloid reactor particles coated with DNA and human enzymes revealed for the first time that a major DNA adduct results from the reaction between B[ghi]P 3,4,11,12-bisoxide and deoxyguanosine. Results also demonstrated 5-fold lower formation rates of the major DNA adduct for B[ghi]P metabolites compared to B[a]P. Overall, results from both the electro-optical array and biocolloid reactor-LC-MS/MS consistently suggest a lower human genotoxicity profile of B[ghi]P than B[a]P. PMID:23879290

  5. Characterisation of a functional intronic polymorphism in the human growth hormone (GHI gene

    2010-06-01

    Full Text Available Abstract The +1169A allele of the A/T single nucleotide polymorphism (SNP; rs2665802, located within intron 4 of the human growth hormone I (GHI gene, has been associated with reduced levels of circulating GH and insulin-like growth factor I, a reduced risk of colorectal cancer and a predisposition to osteoporosis. Whether this intronic SNP is itself the functional polymorphism responsible for exerting a direct effect on GHI gene expression, however, or whether it is instead in linkage disequilibrium with the functional SNP, has been an open question. The evolutionary conservation of the +1169T allele (and the surrounding intronic sequence in the bovine genome, as well as in primate genomes, is, however, suggestive of its functionality. Although a potential alternative splice site spans the location of the +1169 SNP, polymerase chain reaction-based assays failed to yield any evidence for alternative splicing associated with either allele. To determine whether the +1169 SNP, in different allelic combinations with SNPs at -278 (G/T, -57 (T/G and +2103 (C/T, exerts a direct effect on gene expression and/or GH secretion, we performed a series of transfections of various GHI haplotype-expressing constructs into rat GC (somatotroph cells. The results obtained provided evidence to support the contention that the +1169A allele contributes directly to the observed reduction in both GHI gene expression and GH secretion. Part of the apparent influence of the +1169A-bearing allele on GHI gene expression and GH secretion may still, however, be attributable to alleles of additional SNPs in cis to +1169A and located within either the promoter or the 3'-flanking region.

    2011-07-01

    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.)

  10. Resistivity and phase in localized BIA

    Science.gov (United States)

    Shiffman, C. A.; Aaron, R.; Amoss, V.; Therrien, J.; Coomler, K.

    1999-10-01

    We describe a system for highly reproducible non-invasive rf impedance measurements as a function of position along body segments such as the thigh. Results are reported for mainly healthy male and female subjects ranging in age from 19 to 65 and in body-mass index from 15 to 40. A principal conclusion is that the phase of the impedance falls monotonically with increasing distance from the knee, with average values substantially above what is found using standard, whole-body bioelectrical impedance analysis (BIA). To compensate for thigh shape, the data are further analysed using an anatomical model based on reasonable approximations for the distributions of muscle, fat and bone, yielding values of the effective resistivity for current flow parallel to the muscle fibres. The phase and resistivity results are discussed with reference to the whole-body BIA study of maintenance haemodialysis patients by Chertow et al, and in regard to possible physiological correlations observed in this work.

  11. 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.

    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.

    A series of new benzo[ghi]perylenetriimide (BPTI) derivatives has been synthesized and characterized. These remarkably soluble BPTI derivatives show strong optical absorption in the range of ?=300-500?nm and have a high triplet-state energy of 1.67?eV. A cyanophenyl substituent renders BPTI such a strong electron acceptor (Ered =-0.11?V vs. the normal hydrogen electrode) that electron-trapping reactions with O2 and H2 O do not occur. The BPTI radical anion on a fluorine-doped tin oxide|TiO2 electrode is persistent up to tens of seconds (t1/2 =39?s) in air-saturated buffer solution. As a result of favorable packing, theoretical electron mobilities (10(-2) ?10(-1) ?cm(2) ?V(-1) ?s(-1) ) are high and similar to the experimental values observed for perylene diimide and C60 derivatives. Our studies show the potential of the cyanophenyl-modified BPTI compounds as electron acceptors in devices for artificial photosynthesis in water splitting that are also very promising nonfullerene electron-transport materials for organic solar cells.

    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 th...

    One-dimensional supramolecular columnar phases composed of porphyrins (electron donor: D) and benzo[ghi]perylenetriimides (electron acceptor: A) through triple hydrogen bonds have been successfully constructed to perform sequential light-harvesting and electron-transfer processes. A series of benzo[ghi]peryleneimide derivatives have been synthesized to examine the substituent effects such as imide and nitrile groups on the spectroscopic and electrochemical properties. Then, formation of the 1:1 supramolecular complex between zinc porphyrin and benzo[ghi]perylenetriimide derivatives through triple hydrogen bonds was confirmed by Job's plot of (1) H?NMR titration. Next, the one-dimensional supramolecular nanoarrays were successfully prepared in a mixed solvent. X-ray diffraction (XRD) measurement suggested that these nanoarrays contained one-dimensional columnar phases composed of stacked donor and acceptor layers. Finally, femtosecond transient absorption and electron spin resonance (ESR) measurements clearly indicated that photoinduced electron transfer occurred via the singlet excited states in the supramolecular columns.

    2010-01-01

    We have used site-directed mutagenesis, EPR spectroscopy, redox potentiometry, and protein crystallography to monitor assembly of the FS0 [4Fe-4S] cluster and molybdo-bis(pyranopterin guanine dinucleotide) cofactor (Mo-bisPGD) of the Escherichia coli nitrate reductase A (NarGHI) catalytic subunit (NarG). Cys and Ser mutants of NarG-His49 both lack catalytic activity, with only the former assembling FS0 and Mo-bisPGD. Importantly, both prosthetic groups are absent in the NarG-H49S mutant. EPR spectroscopy of the Cys mutant reveals that the Em value of the FS0 cluster is decreased by at least 500 mV, preventing its participation in electron transfer to the Mo-bisPGD cofactor. To demonstrate that decreasing the FS0 cluster Em results in decreased enzyme activity, we mutated a critical Arg residue (NarG-Arg94) in the vicinity of FS0 to a Ser residue. In this case, the Em of FS0 is decreased by 115 mV, with a concomitant decrease in enzyme turnover to ?30% of the wild type. Analysis of the structure of the NarG-H49S mutant reveals two important aspects of NarGHI maturation: (i) apomolybdo-NarGHI is able to bind GDP moieties at their respective P and Q sites in the absence of the Mo-bisPGD cofactor, and (ii) a critical segment of residues in NarG, 49HGVNCTG55, must be correctly positioned to ensure holoenzyme maturation.

    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.

    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.

    Full Text Available Belarusian literature in Poland after 1989. About the necessity of developing a literature databaseSpeaking about Belarusian literature in Poland we focus on fiction, its translation into Polish and the study of literature. The existence of the Belarusian literature in Poland in the post-war period is indicated by the following bibliographies: a bibliography of translations for the period 1945–1994 (G. Charytoniuk, Literatura bia?oruska w Polsce. Bibliografia przek?adów za lata 1945–1994, Bia?ystok 1996 and a subject bibliography for the period 1945–1998 (G. Charytoniuk, Polskie bia?orutenika literackie. Bibliografia przedmiotowa 1945–1998, Bia?ystok 1998. The new political, economical and social conditions in Poland after 1989 have had an influence on the situation of the Belarusian literature. In addition to the existing departments some new university departments and scientific branches have been organized. Their aim is to realize new scientific projects connected with the Belarusian literature in Poland and Belarus. A lot of nongovernment organizations (funds, partnerships, associations have been organized not only in Bialystok region, but also in the other parts of the country. A new publishing market has been established which has focused on the modern literature of Central and Eastern Europe including Belarusian literature. The Internet also plays an important role in popularization of the Belarusian literature. That literature has been included in the database of the National library (Przewodnik Bibliograficzny, Bibliografia Zawarto?ci Czasopism, regional libraries (Bibliografia województwa podlaskiego and the digital library (Polska Bibliografia Literacka. The information is searched by institutional scientific depositories and digital libraries. The considerable part of the information has not been registered in the bibliographic database. In this situation it is necessary to develop an integral literature bibliographic database of the Belarusian literature in Poland. Literatura bia?oruska w Polsce po roku 1989.

    Full Text Available Neste artigo são descritos os aspectos clínicos, laboratoriais e genéticos da investigação da baixa estatura, dando ênfase para o diagnóstico da insensibilidade ao hormônio de crescimento (IGH). O paciente apresentado possuía características clínicas típicas de pacientes com IGH e em idade pré-púber [...] e seus achados laboratoriais eram compatíveis com este diagnóstico (IGF-1 e IGFBP3 baixos, GH basal e pós-estímulo elevados). No entanto, quando avaliado durante a puberdade, as dosagens de IGF-1 e IGFBP-3 foram normais, dificultando o diagnóstico. O estudo molecular identificou mutação no exon 7 do gene do receptor do hormônio de crescimento (S226I). Discutiram-se os passos realizados para identificar a mutação e demonstrar que ela é responsável pelo fenótipo observado no paciente. Também será feita revisão dos casos de IGH descritos no Brasil e dos novos defeitos moleculares descritos nesta doença. Abstract in english It is reported in this study the clinical, laboratory and genetic aspects of short stature investigation with emphasis to the diagnostic approach of growth hormone insensitivity (GHI). This patient in case presented typical clinical features of GHI and his laboratory findings at prepubertal age were [...] typical of those observed in GHI patients (low IGF-1 and IGFBP-3 levels, with high basal and stimulated GH levels). However, during the puberty, he presented normal IGFBP-3 and IGF-1 levels that hindered the diagnosis. The molecular study disclosed a mutation in exon 7 of growth hormone receptor gene (S226I). The steps that demonstrated the causative effect of this mutation are shown here, and also a review of Brazilian GHI cases is given and new molecular defects in this field are discussed as well.

    2015-03-01

    Full Text Available Bia?owieza Forest is the natural habitat of many rare species of green plants, animals and fungi. For centuries, it has been a unique place for developing environmental processes. The water ponds are the wildlife habitat for many organisms, whose lives depend on aquatic environments. Protected species of green plants and animals also live in the water ponds. The aim of this research was to determine the species and quantity of plankton which are present in Bia?owieza Forest’s water ponds. The presence of different species of plankton proved the presence of minimal organic pollution. It was noticed that the primary producers dominated over the other organisms, which confirmed high mineralisation. The water ponds should continue to be monitored, as they are responsible for biodiversity within the Bia?owieza Forest area and they are the best place to settle for many species which are characteristic for swamps and small sources of water.

    Full Text Available Abstract Background Body composition analysis using phase angle (PA, determined by bioelectrical impedance analysis (BIA, reflects tissue electrical properties and has prognostic value in liver cirrhosis. Objective of this prospective study was to investigate clinical use and prognostic value of BIA-derived phase angle and alterations in body composition for hepatitis C infection (HCV following antiviral therapy. Methods 37 consecutive patients with HCV infection were enrolled, BIA was performed, and PA was calculated from each pair of measurements. 22 HCV genotype 3 patients treated for 24 weeks and 15 genotype 1 patients treated for 48 weeks, were examined before and after antiviral treatment and compared to 10 untreated HCV patients at 0, 24, and 48 weeks. Basic laboratory data were correlated to body composition alterations. Results Significant reduction in body fat (BF: 24.2 ± 6.7 kg vs. 19.9 ± 6.6 kg, genotype1; 15.4 ± 10.9 kg vs. 13.2 ± 12.1 kg, genotype 3 and body cell mass (BCM: 27.3 ± 6.8 kg vs. 24.3 ± 7.2 kg, genotype1; 27.7 ± 8.8 kg vs. 24.6 ± 7.6 kg, genotype 3 was found following treatment. PA in genotype 3 patients was significantly lowered after antiviral treatment compared to initial measurements (5.9 ± 0.7° vs. 5.4 ± 0.8°. Total body water (TBW was significantly decreased in treated patients with genotype 1 (41.4 ± 7.9 l vs. 40.8 ± 9.5 l. PA reduction was accompanied by flu-like syndromes, whereas TBW decline was more frequently associated with fatigue and cephalgia. Discussion BIA offers a sophisticated analysis of body composition including BF, BCM, and TBW for HCV patients following antiviral regimens. PA reduction was associated with increased adverse effects of the antiviral therapy allowing a more dynamic therapy application.

    Full Text Available The Bia?a Tarnowska River is a right-bank tributary of Dunajec. It flows from the Low Beskid Mountains, flowing on the border of Ci??kowickie and Ro?nowskie foothills and then flows into the Dunajec on the territory of Vistula Lowland (Nizina Nadwi?la?ska. The aim of this work was to investigate the diatoms diversity at the individual sites and attempt to evaluate pollution of the river with the use diatoms as water quality indicators. The waters of Bia?a Tarnowska River were characterized by alkaline or circumneutral pH. Values of nitrates concentration indicated II water quality class, only at the last site (5 corresponded to the standards for the I class. At the studied sites located along river course 205 diatom taxa were identified. The riches in species were genera: Nitzschia (29, Navicula (21 and Gomphonema (15. The most popular dominant was Achnanthidium pyrenaicum (Hust. Kobayasi. Very numerous communities were created by Navicula lanceolata (Agardh Kütz, at the lower current of river, on two last sites. In order to determine the ecological status of Bia?a Tarnowska River the analysis of the diatom assemblages structure was performed. The results of the analysis were shown by the selected diatomaceous indices. According to IPS index Bia?a Tarnowska has a good ecological status (II class at the most of study sites. Values of TDI index were the worst and indicated poor and bad water quality (IV and V class especially in middle and lower current.

    Propionibacterium freudenreichii belongs to the class Actinobacteria (Gram positive with a high GC content). This "Generally Recognized As Safe" (GRAS) species is traditionally used as (i) a starter for Swiss-type cheeses where it is responsible for holes and aroma production, (ii) a vitamin B12 and propionic acid producer in white biotechnologies, and (iii) a probiotic for use in humans and animals because of its bifidogenic and anti-inflammatory properties. Until now, only strain CIRM-BIA1T had been sequenced, annotated and become publicly available. Strain CIRM-BIA129 (commercially available as ITG P20) has considerable anti-inflammatory potential. Its gene content was compared to that of CIRM-BIA1 T. This strain contains 2384 genes including 1 ribosomal operon, 45 tRNA and 30 pseudogenes. PMID:26779303

    Alkaloids are diverse group of secondary metabolites generally found in plants. Opium poppy (Papaver somniferum L.), the only commercial source of morphinan alkaloids, has been used as a medicinal plant since ancient times. It produces benzylisoquinoline alkaloids (BIA) including the narcotic analgesic morphine, the muscle relaxant papaverine, and the anti-cancer agent noscapine. Though BIAs play crucial roles in many biological mechanisms their steps in biosynthesis and the responsible genes remain to be revealed. In this study, expressions of 3-hydroxy-N-methylcoclaurine 4'-methyltransferase (4'OMT) and reticuline 7-O-methyltransferase (7OMT) genes were subjected to manipulation to functionally characterize their roles in BIA biosynthesis. Measurements of alkaloid accumulation were performed in leaf, stem, and capsule tissues accordingly. Suppression of 4'OMT expression caused reduction in the total alkaloid content in stem tissue whereas total alkaloid content was significantly induced in the capsule. Silencing of the 7OMT gene also caused repression in total alkaloid content in the stem. On the other hand, over-expression of 4'OMT and 7OMT resulted in higher morphine accumulation in the stem but suppressed amount in the capsule. Moreover, differential expression in several BIA synthesis genes (CNMT, TYDC, 6OMT, SAT, COR, 4'OMT, and 7OMT) were observed upon manipulation of 4'OMT and 7OMT expression. Upon silencing and overexpression applications, tissue specific effects of these genes were identified. Manipulation of 4'OMT and 7OMT genes caused differentiated accumulation of BIAs including morphine and noscapine in capsule and stem tissues. PMID:26909086

    A comprehensive radon survey has been carried out in B?i?a radon-prone area, Transylvania, Romania, in 4 localities (B?i?a, Nucet, Fîna?e, and Cîmpani) situated in the vicinity of former Romanian uranium mines. Indoor radon concentrations have been measured in 1128 ground floor rooms and cellars of 303 family houses by using CR-39 diffusion type radon detectors. The annual average of indoor radon concentration for B?i?a area was found to be 241±178 Bq m(-3), which is about two times higher than the average value of 126 Bq m(-3), computed for Romania. About 28% of investigated houses exceed the reference level of radon gas in dwellings of 300 Bq m(-3). The indoor radon measurements on each house have been carried out in several rooms simultaneously with the aim of obtaining a more detailed picture on the exposure to radon in the studied area. An analysis on the variability of radon levels among floors (floor-to-floor variation) and rooms (room-to-room variation) and also the influence of factors like the presence of cellar or the age of the building is presented. The coefficient of variation (CV) within ground floor rooms of the same house (room-to-room variation) ranged between 0.9 and 120.8%, with an arithmetic mean of 46.2%, a large variability among rooms within surveyed dwellings being clearly identified. The mean radon concentration in bedrooms without cellar was higher than in bedrooms above the cellar, the difference being statistically significant (t test, one tail, p0.05). PMID:22664541

  20. Business English in the Eyes of Economics and Management Students at the University of Bia?ystok

    Full Text Available According to the regulations of the Polish Ministry of Science and Higher Education, university graduates should have to know a foreign language at B2 level, as described in The Common European Framework of Reference, and they should know its specialized variety. These are the only recommendations concerning general language courses and their specialized varieties. It is up to schools of foreign languages or other institutions providing language courses for institutions of higher education to determine requirements concerning language for specific purposes. However, students are rarely asked to contribute to the development of curricula and syllabi. This article presents the results of a survey conducted among students of Economics and Management at the University of Bia?ystok. The survey was devoted to students’ perceptions of Business English in English courses conducted by the School of Foreign Languages at the University of Bia?ystok. The aim of the survey was to answer the following questions:

  1. Baltic Sea coastal erosion; a case study from the Jastrz?bia Góra region

    Science.gov (United States)

    U?cinowicz, Grzegorz; Kramarska, Regina; Kaulbarsz, Dorota; Jurys, Leszek; Frydel, Jerzy; Przezdziecki, Piotr; Jegli?ski, Wojciech

    The coastline in the Jastrz?bia Góra area can be divided into three major zones of general importance: a beach and barrier section, a cliff section, and a section protected by a heavy hydrotechnical construction. These areas are characterised by a diverse geology and origin, and hence different vulnerability to erosion. In addition, observations have demonstrated a different pace of erosion within each zone. Based on the results obtained by remote sensing methods (analysis of aerial photographs and maps), it has been determined that the coastline in the barrier area, i.e., to the west of Jastrz?bia Góra, moved landwards by about 130 m, in a period of 100 years, and 80 m over about 50 years. A smaller displacement of the shoreline could be observed within the cliff. Between the middle of the twentieth and the start of the twenty-first centuries the shore retreated by about 25 m. However, in recent years, an active landslide has led to the displacement of the uppermost part of the cliff locally up to 25 m. Another issue is, functioning since 2000, a heavy hydrotechnical construction which has been built in order to protect the most active part of the cliff. The construction is not stable and its western part, over a distance of 50 m, has moved almost 2 m vertically downwards and c. 2.5 m horizontally towards the sea in the past two years. This illustrates that the erosional factor does not comprise only marine abrasion, but also involves land-based processes determined by geology and hydrogeology. Changes in the shoreline at the beach and barrier part are constantly conditioned by rising sea levels, the slightly sloping profile of the sea floor and low elevation values of the backshore and dune areas. Cliffs are destroyed by mass wasting and repetitive storm surges that are responsible for the removal of the colluvium which protects the coast from adverse wave effects. Presumably, mass movements combined with groundwater outflow from the cliff, plus sea abrasion cause destabilisation of the cliff protection construction.

  2. Density, degeneracy, delocalization-based index of aromaticity (D3BIA)

    Full Text Available A aromaticidade tem sido exaustivamente discutida e continua sendo um tema misterioso. Nesse trabalho é proposto um novo índice de aromaticidade chamado índice baseado na densidade-degenerescência-deslocalização ou, simplesmente, D3BIA, numa tentativa de lançar nova introspecção sobre esse tema. Ess [...] e índice é baseado na teoria de átomos em moléculas (AIM) e, de certa forma, é suportado pela teoria dos spins acoplandos (SC). A aromaticidade diminui com o número de heteroátomos na molécula aromática, pois a degenerescência diminui, e diminui com o aumento do tamanho do anel do composto aromático porque desfavorece a sobreposição dos estados monoeletrônicos. A relação entre planaridade do anel, sua densidade eletrônica e aromaticidade é também observada. A interação atrativa da ressonância de 6 elétrons pi no diânion ciclobutadieno compensa sua interação repulsiva carbono-carbono enquanto no seu parente dicatiônico a ressonância de 2 elétrons pi é insuficiente para contrabalancear sua interação repulsiva e adota uma estrutura não-plana. Abstract in english Aromaticity has been exhaustedly discussed for several years and it remains as a misterious issue. In this work it is proposed a new index of aromaticity named density, degeneracy and delocalization-based index of aromaticity or simply D3BIA in an attempt to cast new insight and perspective over thi [...] s theme. This index is based on AIM (atoms in molecules) theory and it is somewhat supported by SC (spin-coupled) theory. Aromaticity decreases as the number of heteroatoms in the aromatic molecule increases since degeneracy decreases and it decreases as the ring size of an aromatic compound increases because it disfavors overlap of single-electron states. The relation between planar structures, electron density and aromaticity is also observed. The attractive interaction of 6pi-electron resonance in cyclobutadiene dianion compensate its carbon-to-carbon repulsive interaction while in its dicationic parent the 2pi-electron resonance is insufficient to counterbalance its carbon-to-carbon repulsive interaction and it adopts a puckered structure.

  3. Bioelectrical impedance analysis (BIA) for sarcopenic obesity (SO) diagnosis in young female subjects

    International Nuclear Information System (INIS)

    Sarcopenia is defined as a loss of muscle mass depending of ageing and affecting physical function (definition A). A new definition considers excluding mass reduction criterion (definition B). Obesity is pandemic and occurs at all ages. Sarcopenic obesity (SO) implies both processes. The purpose of this study was to compare the results obtained after applying these 2 definitions in 66 aged 22 ± 2.8 years overweight or obese young college women. Percentage body fat (%BF) and skeletal mass index (SMI) were estimated by BIA, muscle function by handgrip strength test (HGS) and physical performance by Harvard step test (HST). There were 9.1% and 90.9% overweight or obese subjects. Twenty nine subjects (43.9%) had decreased HGS and 22 (33.3%) had impaired physical performance. One obese subject (1.5%) met the criteria for sarcopenic obesity by definition A and 9 (13.6%) by definition B. Although a linear regression (? 2 = 0.094, 0.037 and 0.275 respectively) it was observed a tendency for HGS, HST and SMI deterioration when %BF increases. However, other confounding factors must be investigated. Probably as the population gets more obese, the problematic of SO will be found earlier in life.

    Full Text Available The aim of the study was to analyze the species composition of the dendroflora near four main roads in the city of Bia?ystok, taking into regard their geographical and historical origin. The wildlife inventory was conducted in the vegetation season of 2011. The inventory revealed presence of a total of 837 trees and bushes representing 36 species and 18 families. The most abundant trees were those from the family Aceraceae (63.8%, while the most abundant bushes were those representing Rosaceae (48.9%. The contribution of native species (65.7% was found to be about twice as high as that of alien ones (34.3%. The dominant species among the native trees was Acer platanoides L., while the principal bush species was Crataegus monogyna Jacq. The alien tree species were most commonly represented by Acer negundo L., and bushes - by Ligustrum vulgare L. Spontaneously settled trees and bushes were clearly dominant (59.9% over those originating from plantations (40.1%. Among the native species of local origin, the prevailing species were synanthropic spontaneophytes (52%, including Acer platanoides and Tilia cordata Mill. Anthropophytes were more abundantly represented by diaphytes (22.7%, followed by kenophytes (10.4%. The most abundant species among diaphytes was Ligustrum vulgare, and among kenophytes - Acer negundo.

    The Bureau of Indian Affairs (BIA) is responsible for the natural resource management of approximately 52 million acres of Trust lands in the contiguous United States. The lands are distributed in a "patchwork" fashion throughout the country. Management responsibilities on these areas include: minerals, range, timber, fish and wildlife, agricultural, cultural, and archaeological resources. In an age of decreasing natural resources and increasing natural resource values, effective multiple resource management is critical. BIA has adopted a "systems approach" to natural resource management which utilizes Geographic Information System (GIS) technology. The GIS encompasses a continuum of spatial and relational data elements, and included functional capabilities such as: data collection, data entry, data base development, data analysis, data base management, display, and report generalization. In support of database development activities, BIA and BLM/TGS conducted a cooperative effort to investigate the potential of 1:100,000 scale Thematic Mapper (TM) False Color Composites (FCCs) for providing vegetation information suitable for input to the GIS and to later be incorporated as a generalized Bureau wide land cover map. Land cover information is critical as the majority of reservations currently have no land cover information in either map or digital form. This poster outlines an approach which includes the manual interpretation of land cover using TM FCCs, the digitizing of interpreted polygons, and the editing of digital data, used upon ground truthing exercises. An efficient and cost-effective methodology for generating large area land cover information is illustrated for the Mineral Strip area on the San Carlos Indian Reservation in Arizona. Techniques which capitalize on the knowledge of the local natural resources professionals, while minimizing machine processing requirements, are suggested.

  7. The ancestral conservative tillage of silver fir in the ‘Tisovik’ reserve of the Bia?owie?a Primeval Forest

    Full Text Available The ‘Tisovik’reserve, located in the Belarusian part of the Bia?owie?a Forest, holds an isolated relic stand of silver fir, situated 120 km to the north-east of the main forest. In order to preserve this relic fir stand, a ancestral conservative tillage consisting of the Jd 92 trial (plot I and the Jd 94 trial (plots II and III was established between 1992 and 1994 in the Polish part of the Bia?owie?a Forest on the territory of the Hajnówka Forest District. The growth and development of the progeny of 20 firs were characterized by means of long-term observations made in these trials. In 2000 (at the age of 18, the firs in the Jd 92 trial (plot I reached an average height of 394.86 cm with a mean diameter at breast height of 42.42 mm and the average rate of survival amounted to 75%. In the Jd 94 trial, the rate of fir survival on plot II was 70% (at the age of 15 with an average height of 277.08 cm and a diameter at breast height of 36.62 mm, while on plot III only 50 trees with an average height of 198.6 cm and a diameter at breast height of 24.49 mm survived. The results of this study show that the fir progeny in the ‘Tisovik’ reserve is of high breeding value. Therefore, the silver fir seed stock of the ‘Tisovik’ reserve is suitable for the establishment of new plantations in the Polish part of the Bia?owie?a Forest and the Mazury-Podlasie Region.

  8. Forms of Physical Activity of Bia?a Podlaska Preschool Children

    2014-09-01

    Full Text Available Introduction. Physical activity is fundamental to children's all-round development in the first six years of their life. It is particularly significant in preschool age, when the need for movement is predominant. Psychomotor development, conditioned by children's innate abilities and their own activity, depends upon the influence of external surroundings as well as parental upbringing and preschool education. The aim of the study was to obtain data regarding physical activity (both structured and unstructured of children during their stay in a kindergarten. Material and methods. The study was conducted in five state kindergartens situated in four main housing estates of Bia³a Podlaska. It included 11 groups of older preschool children. It was a diagnostic study. A diagnostic poll method employed in the study included interviews with teachers, lesson observations (during one day and document analyses (programmes and class registers. Results. During their stay in a kindergarten children take part in physical activities for 1.5 hours a day. During this period they participate in obligatory forms of physical activity such as morning gymnastics, movement plays, outdoor activities and gymnastic exercises. Furthermore, optional movement activities are organised in kindergartens (different forms in different kindergartens. Such extra classes enable children to be physically active for over two more hours per week. Conclusions. In terms of caring about health and motor development of children, not all elements of preschool education programmes are fully realised. Training sessions, workshops and lectures showing diverse forms of physical activity for children ought to be organised for preschool teachers.

  9. Movements of European bison (Bison bonasus) beyond the Bia?owie?a Forest (NE Poland): range expansion or partial migrations?

    The European bison is the largest terrestrial mammal in Europe. After extinction in the wild at the beginning of the twentieth century, it was re-introduced to Bia?owie?a Forest and other woodlands in Eastern Europe. In this paper, we analysed the movements of European bison beyond the continuous woodlands of the Bia?owie?a Forest (NE Poland) between 1964 and 2010. In total, 1,117 direct observations of bison were collected. The number of males moving out of the forest fluctuated during the study period, whilst the number of females steadily increased. The number of male observations outside of the forest per annum was dependent on the population size and snow depth, whilst the number of cows in mixed groups moving outside of the forest was correlated with the population size only. Males were observed mainly alone (50 % of observations) or in small groups of two to three individuals (25 %); however, distribution of group size differed from those observed in the population. There was a significant difference between the direction of movement of males and females out of the forest-males moved mainly west and southwest, whilst females moved to the north. This was also significantly different from the expected movement direction. The mean distance of bison observations from the forest border was 1.8?±?0.13 km and did not differ significantly between sexes. After 1990, males were observed significantly farther away from the forest (2.2 km) than in the previous years (0.9 km). Most observations (94 % of bulls and 93 % of cows) were up to 5 km from the forest edge. The range of bison in the vicinity of the Bia?owie?a Forest was strictly seasonal. Most observations (78 % in males and 88 % in females) were recorded from November to April. Increasing utilisation of areas beyond the forest habitats may be driven by different factors but most probably it is related to range expansion and the bison's preference for open habitats. The strong seasonal pattern of bison movements indicate that the partial seasonal migrations were initiated in the Bia?owie?a population. PMID:24244043

    Full Text Available The process of pigs producer groups formation in Poland is quite dynamic. Currently on the pork market 181 groups operate, which includes about 4000 swine producers. The aim of this study was to characterize the activities of the Agricultural Producers Association in Bia?a District. The research tool was a personal questionnaire and the research sample consisted of 30 farmers. It has been shown that after joining the producers group, the investigated households reported an increase in sales volume and improved the flock production parameters. Majority of the respondents were not satisfied with the cooperation with meat processing companies.

    Matuszkiewicz Jan Marek

    2014-09-01

    Full Text Available During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia, rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Bia?owie?a National Park (NE-Poland indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

    Full Text Available Information on elephant ranges and numbers is vital for effective conservation and management, especially in western Africa where elephant populations are small and scattered.  The Bia Conservation Area (BCA in southwestern Ghana is a priority site for the conservation of Forest Elephants in western Africa.  A dung count was conducted using a systematic segmented track line design to determine the density and distribution of the BCA elephant population.  The mean density of dung-piles was 452.15 per sq.km. and mean dung survival time was estimated to be 54.64 days (SD 2 days, leading to an estimate of 146 elephants (95% confidence interval 98-172 with a density of 0.48/km2 for the BCA. This estimate probably makes the Bia forest elephant population the largest in Ghana.  Records of BCA elephant activities were also made.  This study augments the Regional African Elephant Database and should facilitate strategic planning and management programmes.

    One hundred fecal samples were collected during research on Eurasian lynx ecology and food habits in the Polish part of the Bia?owieza Primeval Forest (BPF) from 2001 to 2006. Seventy-three percent of samples contained eggs or larvae of helminths. A total of 10 species of helminths was identified, including 3 Cestoda (Diphyllobothrium latum, Spirometra janickii, and unidentified species of Taeniidae), 1 Trematoda (Alaria alata), and 6 Nematoda (Aelurostrongylus abstrusus, Ancylostoma tubaeforme, Eucoleus aerophilus, Metastrongylus sp., Nematodirus sp., and Toxocara cati). Alaria alata has not been reported previously in lynx. A statistical comparison of the 2 techniques used to isolate eggs, i.e., flotation and sedimentation, indicates that sedimentation was more effective. PMID:18576790

    We analyzed habitat requirements of Boros schneideri (Panzer, 1796) (Coleoptera: Boridae) in the natural forests of the continental biogeographical region, using data collected in the Bia?owie?a Forest. This species has been found on the six host trees, but it preferred dead, standing pine trees, characterized by large diameter, moderately moist and moist phloem but avoided trees in sunny locations. It occurred mostly in mesic and wet coniferous forests. This species demonstrated preferences for old tree stands (over 140-yr old), and its occurrence in younger tree-stand age classes (minimum 31-40-yr old) was not significantly different from random distribution. B. schneideri occupied more frequently locations distant from the forest edge, which were less affected by logging. Considering habitat requirements, character of occurrence, and decreasing number of occupied locations in the whole range of distribution, this species can be treated as relict of primeval forests.

    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.

If the seed-producing silver-fir stands really originated from the Cisovka population, then they are a very valuable part of the declining population and an easy accessible seed source. However, if these populations were introduced to the Bia?owie?a Primeval Forest, then they are a potential source of dangerous genetic pollution of the Cisovka population. The relationship of the genetic structure of the Cisovka population to man-made silver-fir-stands in Bia?owie?a Forest was investigated with the help of 17 loci of 1 1 enzyme systems. Genetic diversity of Cisovka population is characterized by the smallest mean number of alleles per locus (Mal= 1.353, includes all loci studied and per polimorphic locus Malp = 2.00. In Cisovka population there is very low-grade of polimorphic loci (Pp = 11.765 with the mean 37.255 for all studied populations. Expected heterozygosity, He = 0.079 revealed very low-grade of genetic diversity in the population. The observed heterozygosity (Ho = 0.123 was similar to this characterictic in other populations. A dendrogram based on Neis genetic distance coefficient (D among 9 silver-fir populations was constructed. Cisovka in the UPGMA dendrogram is a distinct population separated from other ones by a very great genetic distance (D = 0.06. Also two man-made silver-fir (B I and 132 stands are separated from others. Only populations B3 and B4 are combined into one subgroup linked to the population Tomaszów Lubelski. Basing on the received results one should decide that all the four studied artificial stands were introduced to Bia?owie?a Primeval Forest from beyond of this geographical regions. There is some reason to assume (on the GDH2 allele frequency that man-made silver-stands in compartments 453Aa and 498Cg are of eastern provenance. It is rather certain that these stands are not of offspring of Cisovka populations.

    Full Text Available Elements of the Belarusian language in the Russian dialect used by the Old Believers living in the Suwa?ki-Augustów regionThe article deals with the Belarusian elements in the Russian dialect of the Old Believers living in Poland. The Old Believers arrived in Poland in the second half of the 18th century. At present they live in the Suwa?ki-Augustów region in the north-eastern Poland. They inhabit mostly two villages in the county of Suwa?ki, namely Gabowe Gr?dy and Bór, which are very close to each other, and three towns: Augustów, Suwa?ki and Sejny. The dialect used by the Polish Old Believers represents the western Central Great Russian dialects characterized by akanie, the so-called Pskov group. They share features which are typical of Pskov. The dialect was also influenced by other north-eastern Belarusian dialects, that is, the ones which were closest to the areas originally inhabited by Old Believers, who migrated in phases. After each phase, their dialect came to reflect some new linguistic influences. A large number of lexemes directly borrowed from Polish, or via the Belarusian language, are found in this dialect, which is also characterized by other features common in Belarusian dialects or the Bulgarian language. By way of illustration, they include the following features: the prosthetic j-, prosthetic v-, the occurrence of the endings –im and –ym in the case of singular masculine adjectives in the locative, promotion of the endings –i and –y in the case of the plural masculine and neutral nouns in the nominative, and the occurrence of lexemes borrowed from the Belarusian language. Bia?oruskie elementy j?zykowe w rosyjskiej gwarze staroobrz?dowców mieszkaj?cych w regionie suwalsko-augustowskimArtyku? po?wi?cony jest problematyce bia?oruskich elementów j?zykowych w rosyjskiej gwarze staroobrz?dowców mieszkaj?cych w Polsce.

    1.?The disposition etamicastat was evaluated in the Cynomolgus monkey after intravenous and oral administration of [(14)C]-etamicastat. The pharmacokinetics of etamicastat and its N-acetylated metabolite BIA 5-961 were also evaluated in monkeys and dogs. 2.?In the monkey, 7 days after intravenous and oral administration of [(14)C]-etamicastat, 76.6-91.1% of the etamicastat-related radioactivity had been excreted mainly in urine. The radioactivity peaked in plasma between 4- and 8-h post-dosing followed by a quick decline and a slow terminal phase (half-life of 68.7?h). The calculated oral bioavailability for etamicastat was 46.1%. Etamicastat was quickly absorbed in monkeys and dogs with a half-life ranging from 5.2 to 9.9?h in monkeys and 6.9 to 11.4?h in dogs over. 3.?The N-acetylated metabolite of etamicastat, represented 4-7% of the extent of exposure of etamicastat in the monkey, but was not found detectable in dogs. Gender did not influence etamicastat exposure and the concentration versus time curves fitted a dose-dependent pharmacokinetics in the dog, but not in the monkey. 4.?In conclusion, etamicastat is rapidly absorbed and primarily excreted via urine in monkeys. Similarly, to humans, monkeys, unlike dogs, N-acetylate etamicastat and evidence that etamicastat pharmacokinetics is less than dose proportional. PMID:25869244

    Highlights: • [Fe(PM-BIA){sub 2}(NCS){sub 2}] is identified in high and low spin states, showing spin crossover. • DFT studies provide charges and Morse potentials used in MD for orthorhombic phase. • DFT and MD simulations reproduce thermodynamics leading to enthalpy variation. • Spin crossover T{sub 1/2} calculated within range of experiment from enthalpies and structure. • Calculated (P, T) phase diagram shows monoclinic polymorph in two spin states. - Abstract: The spin crossover properties and the domains of existence of the different phases for the [Fe(PM-BIA){sub 2}(NCS){sub 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 aim of the study was the analysis of pregnancy outcome, newborn status, metabolic control and obstetric failure in 365 pregnant diabetic patients treated in Bia?ystok Diabetic-Obstetric Center. Abortions occurred in 1.64% of pregnancies, intrauterine deaths--in 1.1%, and newborns deaths--in 2.47% cases. Macrosomia was observed in 14.8% of children (from 12% in type 1--up to 25% in gestational diabetes class G2). Congenital malformations were seen in 16 newborns of type 1 diabetic women (9.6%), 2 newborns of type 2 diabetics (22.2%), 6 children of mothers with gestational diabetes class G1 (4.2%) and 4 (8.3%)--class G2. The discussion underlines the role of a long duration of the disease as a key factor increasing the risk of complications and the importance of a good metabolic control before and shortly after conception.

    Full Text Available The study presents the analysis of the findings of 234 post-mortem examinations on free-ranging and captive European bison selectively culled or having fallen between 2008 and 2013 in Białowieża Primeval Forest. Pneumonia, emphysema, nephritis, bodily traumas, and intestinal lesions were observed in 106 (45.3%, 77 (32.9%, 82 (35.0%, 68 (29.1%, and 56 (23.9% animals respectively and were the most common pathological changes. Almost half of all males (66 out of 140; 47.1% tested showed some pathological changes of prepuce and penis, described as posthitis or balanoposthitis. Infection with liver fluke (Fasciola hepatica and lungworm (Dictyocaulus viviparus was observed macroscopically in 114 (48.7% and 80 (32.9% bison respectively. F. hepatica prevalence was associated with the emergence of other liver changes such as hepatitis and cirrhosis (P < 0.001. Similarly, the prevalence of D. viviparus coincided with pneumonia (P = 0.001, changes in the upper respiratory tract (P = 0.04, and emphysema (P < 0.001. Hepatitis, infection with F. hepatica, and pathological lesions in the male and female reproductive tracts were associated with the animals’ age. Mechanical injuries, caused by other bison or less commonly by traffic accidents, were the most common cause of death of bison below six months of age. Most pathological changes were significantly more frequent in the selectively culled animals in comparison with the ones having fallen, which confirms the desirability of elimination as a tool to improve the health and welfare of the bison population and limit the number of reservoirs of invasive and possibly infectious diseases.

  7. Molecular mechanisms of xylose utilization by Pseudomonas fluorescens: overlapping genetic responses to xylose, xylulose, ribose and mannitol.

    Bacterial degradation of xylose is sequentially mediated by two enzymes - an isomerase (XutA) and a xylulokinase (XutB) - with xylulose as an intermediate. Pseudomonas fluorescens?SBW25, though capable of growth on xylose as a sole carbon source, encodes only one degradative enzyme XutA at the xylose utilization (xut) locus. Here, using site-directed mutagenesis and transcriptional assays, we have identified two functional xylulokinase-encoding genes (xutB1 and xutB2) and further show that expression of xutB1 is specifically induced by xylose. Surprisingly, xylose-induced xutB1 expression is mediated by the mannitol-responsive regulator MtlR, using xylulose rather than xylose as the direct inducer. In contrast, expression of the xutA operon is regulated by XutR - a transcriptional activator of the AraC family - in a xylose-, xylulose- and ribose-dependent manner. Detailed genetic and biochemical analyses of XutR, including DNase I footprinting assays, suggest an unconventional model of XutR regulation that does not involve DNA-looping, a mechanism typically found for AraC-type regulators from enteric bacteria. XutR functions as a dimer and recognizes two inverted repeat sequences, but binding to one half site is weak thus requiring an inducer molecule such as xylose for activation. PMID:26194109

  8. The origin of the Avram Iancu U-Ni-Co-Bi-As mineralization, B?i?a (Bihor) metallogenic district, Bihor Mts., Romania

    The B?i?a metallogenic district in the Bihor Mountains is a historically important mining area in Romania. Uranium mining took place between 1952 and 1998 from various deposits, but very little is known about the geology and mineralogy of these deposits. In this paper, we describe geology and mineralogy of uranium mineralization of the Avram Iancu uranium mine from waste dump samples collected before complete remediation of the site. Texturally and mineralogically complex assemblages of nickeline, cobaltite-gersdorffite solid solution, native Bi, Bi-sulfosalts, molybdenite, and pyrite-chalcopyrite-sphalerite occur with uraninite, "pitchblende," and brannerite in most of the ore samples. The association of nickel, cobalt, and arsenic with uranium is reminiscent of five-element association of vein type U-Ni-Co-Bi-As deposits; however, the Avram Iancu ores appear to be more replacement-type stratiform/stratabound. Avram Iancu ore samples contain multistage complex, skarn, uranium sulfide, arsenide assemblages that can be interpreted to have been formed in the retrograde cooling stages of the skarn hydrothermal system. This mineralizing system may have built-up along Upper Cretaceous-Paleogene "Banatite" intrusions of diorite-to-granite composition. The intrusions crosscut the underlying uraniferous Permian formations in the stacked NW-verging Biharia Nappe System. The mineralization forms stacked, multilayer replacement horizons, along carbonate-rich lithologies within the metavolcanic (tuffaceous) Muncel Series. Mineral paragenesis and some mineral chemistry suggest moderate-to-high <450, i.e., 350-310 °C, formation temperatures for the uranium sulfide stage along stratigraphically controlled replacement zones and minor veins. Uranium minerals formed abundantly in this early stage and include botryoidal, sooty and euhedral uraninite, brannerite, and coffinite. Later and/or lower-temperature mineral assemblages include heterogeneous, complexly zoned arsenide-sulfarsenide solid solutions associated with minute but abundant uranium minerals. Within the later arsenide-sulfarsenide mineral assemblage, there is great variation in Ni, Co, and S content with generally increasing arsenic content. Uranium minerals in this late-stage assemblage include very fine euhedral uraninite and brannerite inclusions in arsenide-sulfarsenide minerals. Native bismuth and Bi-sulfosalt krupkaite are observed in this As-S-rich assemblage strongly associated with cobaltite.

Objetivo. Describir la composición corporal, el agua corporal total y el peso seco de pacientes con enfermedad renal en Hemodiálisis Materiales y Métodos. Se realizó un estudio descriptivo transversal en seis fases, desde el año 2001 al 2010. Con el método de BIA-1 Y BIA-4 (bioimpedancia de unifrecuencia y tetrapolar) y la ecuación Ramírez-Almanza. Para la determinación del peso seco se utilizaron los valores de normovolemia e hipervolemia y se utilizó un nuevo instrumento para diagnóstico nutricional VGS-MIS. Resultados. El 50% de los pacientes estudiados tenían un diagnóstico de Diabetes e Hipertensión, el 87% con riesgo leve de desnutrición, solo el 3% sin riesgo de desnutrición. El punto de cohorte de la Resistencia dada por la bioimpedancia de 550 permite determinar que pacientes con valores por debajo de éste son sintomáticos con una alta sensibilidad 73% y una especificidad de 50%. Para el agua total corporal es posible utilizar la ecuación Ramirez-Almanza pues tiene una buena correlacion mediana (0.76)con el índice de impedancia de Kushner. La VGS-MIS es el mejor método de valoración encontrada hasta ahora para paciente renal porque involucra diferentes parámetros físicos, nutricionales, clìnicos y bioquímicos. Conclusión.

    Full Text Available 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.

The following crops were used for silage production: triticale (X. Triticosecale Wittimack, triticale intercropped with forage pea (Pisum arvense and triticale intercropped with oats (Avena strigosa Schreb, forage pea and vetch (Vicia sativa. The dry matter content and its recovery did not differ among the silages. Buffer capacity was higher for tricale silage intercropped with oats, forage pea and vetch(88.67 m eq. NaOH/100 g DM followed by triticale intercropped with forage pea (80.80 m eq. NaOH/100 g DM. Electric conductivity values were higher in the intercropped triticale silages. Triticale silage presented the lowest temperatures observed in the silos, and the silages of intercropped triticale silages presented higher heat retention and higher pH values. Silage of triticale intercropped with oats and legumes presented lower aerobic stability but it did not reduce the aerobic stability of the total feed. Dry matter recovery during storage and in stability evaluations in aerobiosis is similar among the silages.O objetivo neste trabalho foi avaliar a estabilidade aeróbia e as perdas durante o processo de fermentação de silagens de triticale em cultivo exclusivo ou em misturas com aveia e/ou leguminosas.

    I will describe the methodology used to develop and deploy operationally a comprehensive solar forecasting system for both concentrated and non-concentrated solar technologies. This operational forecasting system ingests data from local telemetry, remote sensing and Numerical Weather Prediction (NWP) models, processes all the diferent types of data (time series, sky images, satellite images, gridded data, etc.) to produce concatenated solar forecasts from 5 minutes out to 72 hours into the future. Each forecast is optimized with stochastic learning techniques that include input selection, model topology optimization, model output statistics, metric fitness optimization and machine learning. These forecasts are used by solar generators (plant managers), utilities and independent system operators for operations, scheduling, dispatching and market participation.

Para isso, foram estudados 11 mesatenistas com tempo mínimo de treinamento de dois anos. Foram aplicados os testes de: 1 lactato mínimo em duas ocasiões para análise da reprodutibilidade (LACmin1 e LACmin2; 2 teste de freqüência crítica (fcrit; 3 teste incremental para determinação do limiar anaeróbio através da concentração fixa de lactato de 3,5mM (LAn esp3,5 e regressão linear bissegmentada (LAnBI, todos em procedimentos específicos para o tênis de mesa; e 4 o limiar anaeróbio em corrida aplicado em esteira rolante (LAn est determinado pela concentração fixa de lactato de 3,5mM. Nos procedimentos específicos foi utilizado um lançador de bolas mecânico como ergômetro e os participantes realizaram golpes apenas de forehand. Como procedimentos estatísticos foram utilizados os testes de Bland-Altman, correlação produto-momento e ANOVA one way, com nível de significância de 5%. As intensidades de LACmin (59,40 ± 4,06 e 61,56 ± 8,97 bolas.min-1 apresentaram boa concordância (teste de Bland-Altman e foram significativamente correlacionadas (0,61. A fcrit, o LAn esp3,5 e o LAnBI foram correspondentes a 56,50 ± 6,84 bolas.min-1; 66,74 ± 5,03 bolas.min-1; e 62,67 ± 7,25 bolas.min-1, respectivamente. Foi verificada apenas diferença significativa entre as intensidades de LAn esp3,5 e de fcrit. Foram encontradas correlações significativas entre LACmin1 e LACmin2 (0,61, LACmin1 e fcrit (0,61, LACmin2 e fcrit (0,69, LAn esp3,5 e LAnBI (0,70, enquanto que o LAn est (9,11 ± 1,94km.h-1 foi apenas correlacionado com a intensidade de fcrit (0,73. Desse modo, pode-se concluir que o teste de LACmin específico é reprodutível e que esse procedimento, assim como o teste de fcrit, pode ser aplicado para avaliar a transição aeróbia-anaeróbia no tênis de mesa e que o LAn est deve ser utilizado com cautela na avaliação de mesatenistas.The aims of the present study were to adapt the lactate minimum, critical power model and anaerobic threshold tests for assessment of the aerobic-anaerobic transition in specific test for table tennis; to verify the reproducibility of the lactate minimum test and to verify the relationship between these specific procedures with the anaerobic threshold determined in running on treadmill (AnT TR. Eleven male table tennis players participated in the study. The participants performed four tests (three specific tests and a conventional test performed on a treadmill: 1 lactate minimum test (LACmin (applied twice for reproducibility analyses - LACmim1 and LACmin2; 2 critical frequency test (critf; 3 incremental test for anaerobic threshold determination by 3.5 mM steady lactate concentration (AnT3.5 and bi-segmented linear regression (AnT BI methods, all in specific protocol; and 4 anaerobic threshold on running (AnT TR. Specific tests were applied by using a mechanical ball thrower to control the intensity of the exercise. The Bland-Altman plot, product-moment correlation and One-way ANOVA tests were used as statistical procedure, with significance level at 5%. The LACmin intensities (59.40 ± 4.06 balls.min-1 and 61.56 ± 8.97 balls.min-1 presented significant correlation (r = 0.61 and moderate concordance verified by Bland-Altman plot. The critf, AnT3.5 and AnT BI intensities corresponded to 56.50 ± 6.84 balls.min-1, 66.74 ± 5.03 balls.min-1 and 62.67 ± 7.25 balls.min-1, respectively, and only AnT3.5 and critf were different. Significant correlations were obtained amongst LACmin1 and critf (r = 0.61, LACmin2 and critf (r = 0.69, and AnT3.5 and AnT BI (r = 0.70. Anaerobic threshold determined in running (9.11 ± 1.94 Km.h-1 was only correlated with the critf (r = 0.73. Thus, in conclusion, the lactate minimum test specific for table tennis is a reproducible procedure, as well as the critf test can be applied for evaluating aerobic-anaerobic transition. Neverhteless, the anaerobic threshold applied in running on a treadmill must be used with care in table tennis.

    Full Text Available Polish language in the Republic of Belarus The situation of the Polish minority in Belarus was always difficult because the politics of Belarusian authorities was focused on destruction of anything connected with Polish culture or possessing Polish roots: intelligentsia, school, theatres, press. The reestablishing of Polish education in late 80-ties of the last century started from scratch therefore and the biggest amount of learners studied Polish in late 90-ties of the XX century. Recently the amount of students has decreased which is explained by the current demographical and political situation. The most significant influence on forming national consciousness is possesses by family. Unfortunately nowadays it is being observed that most of Polish families has not performed that function anymore and using of Polish language by members of Polish families is decreasing. The leading role of Polish language in a Catholic liturgy is changing as well: the word “Catholic” does not mean “Pole”. According to surveys 66% of Catholics would prefer Polish as the language of liturgy, 20% – Belarusian, 10% – Russian and Polish, 4% – another language. This situation creates the possibility of disappearing of Polish language from liturgy and catechism. Consequently the role of Polish schools and organizations in education of children and teenagers has increased. Language acquisition begins in kindergartens during extra lessons or within Polish groups. The forms of language acquisition at school vary a lot. Most of the students learn Polish languages after-hours, some of them attends required Polish classes at school. Moreover there are two Polish schools of Grodno region. There is an opportunity of studying Polish language in high educational establishments in Belarus, e.g. in Grodno State University Polish language department has existed since 1989 and it prepares its students to teaching Polish language. Farther development of Polish education in Belarus depends on both factors the Poles attitude and current political situation in the country. ???????? ???? ? ?????????? ????????????????? ????????? ????????????? ??????????? ? ?? ?????? ???? ???????, ??? ??? ???????? ??????? ???? ?????????? ?? ??????????? ?????, ??? ????? ???????? ????? ? ???? ??????? ? ???????? ?????????: ?????????????, ????, ???????, ?????. ? ????? ? ???? ??????????? ??????????? ?? ???????? ????? ? ????? 80-??? ????? ???????? ???????? ?????????? ? ???????? ?????? ? ?????????? ?????????? ???????? ??????? ???????? ???? ? ????? 90-??? ?????

    Full Text Available CONTEXTUALIZAÇÃO: Recursos eletrofísicos, como o ultrassom (US e a terapia laser de baixa potência (LLLT, vêm sendo cada vez mais utilizados na prática fisioterapêutica. Estudos sugerem que esses recursos são capazes de estimular a proliferação de osteoblastos e a osteogênese no local da fratura, promovendo maior deposição de massa óssea e acelerando o processo de consolidação. OBJETIVO: Analisar os efeitos do US e da LLLT no processo de consolidação óssea por meio das análises biomecânica e histológica do calo ósseo. MÉTODOS: Foram utilizados 30 ratos machos, distribuídos aleatoriamente em três grupos: grupo controle fratura, sem tratamento (GC; grupo fratura tratado com US pulsado com burst de 1,5 MHz, 200us, 1KHz, 30 mW/cm² (GUS e grupo fratura tratado com laser 830nm, 100mW, 120J/cm² (GL. Foram realizados defeitos ósseos circulares com broca de 2 mm de diâmetro nas tíbias dos animais. Os tratamentos foram realizados a cada 48 horas, totalizando sete aplicações e, no 14º dia, os animais foram sacrificados. A tíbia direita foi designada para análise biomecânica, enquanto a esquerda, para análise histológica. RESULTADOS: A análise biomecânica não mostrou diferença estatisticamente significativa entre as propriedades biomecânicas do GC, GL e GUS. Na análise morfométrica, tanto GUS quanto GL apresentaram área de osso neoformado estatisticamente maior em relação ao GC. No entanto, quando as duas modalidades de tratamento foram comparadas, não foram encontradas diferenças estatísticas entre elas. CONCLUSÃO: Ambos os recursos utilizados neste estudo foram capazes de acelerar o processo de reparo ósseo em ratos.BACKGROUND: Electrophysical agents such as Ultrasound (US and low-level laser therapy (LLLT have been increasingly used in physical therapy practice. Studies suggest that these devices are able to stimulate osteoblast proliferation and osteogenesis at the fracture site, resulting in a greater deposition of bone mass and speeding up the consolidation process. OBJECTIVE: The aim of this study was to analyze the effects of US and LLLT on the bone healing process, through biomechanical and histological analysis of the bone callus. METHODS: A total of 30 rats were randomly allocated into three groups: control group fracture without treatment (GC; fracture group treated with pulsed US, burst 1.5 MHz, 200us, 1KHz, 30 mW/cm² (GUS and fracture group treated with laser 830nm, 100mW, 120J/cm² (GL. Bone defects were performed with a circular drill of 2mm in diameter in the animal's tibias. The treatments were carried out after surgery consisting of 7 applications every 48 hours. After 14 days the animals were sacrificed and the tibias were removed to perform the analysis, being the right tibia designated for biomechanical analysis, while the left tibia for histological analysis. RESULTS: The biomechanical analysis showed no statistically significant difference between biomechanical properties of the CG, CL and GUS. In morphometric analysis, both GUS and GL showed a significantly higher woven bone tissue area compared to the control group. However, when the two treatment modalities were compared, there were no statistical differences between them. CONCLUSION: Both devices used in this study were able to accelerate the bone healing process in rats.

    Full Text Available Os objetivos deste estudo foram avaliar a translação anterior da tíbia (TAT, pico de torque isométrico e atividade eletromiográfica de indivíduos com lesão do ligamento cruzado anterior (LCA realizando contrações isométricas em cadeia cinética aberta no ângulo de 30º de flexão do joelho. Foram avaliados 20 voluntários do sexo masculino (31.1 ± 7.45 anos com ruptura completa do LCA e 20 indivíduos controle (22.2 ± 3.15 anos. Eletromiografia de superfície, artrômetro KT 1000 e um Dinamômetro isocinético foram utilizados para avaliar a atividade EMG do Quadríceps e Isquiotibiais, TAT passiva e ativa e pico de torque isométrico respectivamente durante três contrações isométricas voluntária máxima a 30 º de flexão do joelho. Os resultados demonstraram que a TAT passiva e ativa é significativamente maior em joelhos com lesão do LCA comparado ao joelho contralateral, lado dominante e não dominante do grupo controle, porém os valores da TAT ativa foram menores do que a passiva. Não houve diferenças estatisticamente significativas entre os grupos na atividade EMG do quadríceps e isquiotibiais e no pico de torque isométrico produzido durante o tarefa motora requisitada. Os resultados deste estudo demonstram que indivíduos com lesão do LCA e indivíduos controle se comportam de maneira similar em relação a pico de torque isométrico e controle motor embora a artrocinemática da articulação tibiofemural mostrou-se diferente em joelhos lesados.The aim of this study was to evaluated the anterior tibial translation (ATT, isometric peak torque and EMG activity in individuals with acl rupture performing isometric contraction in open kinetic chain in angle that provoke substantial ATT. It was evaluated 20 male subjects (31.1± 7.45 years with acl total rupture and 20 control subjects (22.2 ± 3.15 years. Electromyography, arthrometric kt 1000 and isokinetic dynamometry was used to evaluate the quadriceps and hamstrings EMG activity, passive and active ATT and isometric peak torque respectively during three maximum isometric voluntary contractions at 30 degrees of knee flexion. The results demonstrated that the passive and active ATT is significant greater in knees with acl rupture compared with the contralateral knees, dominant and non dominant knees of the control group. However the active ATT values were greater than the passive ATT. There is no statistic significant differences between groups concerning quadriceps and hamstring EMG activity and in the peak torque produced during the motor task requested. The results of this study demonstrated that individuals with acl rupture had similar behavior compared with normal knees in relation to isometric peak torque and motor control despite the different arthrokinematics of the tibiofemural joint observed in injured knees.

    Full Text Available Observations on the Polish lexis in Lithuania on the borderland of Lithuania, Latvia and BelarusThe paper comments on the lexicon of Polish on the borderland of Lithuania, Latvia and Belarus (in the Zarasai district and the Ignalina district in Lithuania. The remarks, illustrated with selected examples, have been formulated on the basis of data gathered during field research in 2000–2001 and 2010–2011. The paper aims primarily at discussing the extent to which the collected material contributes to the state-of-the-art knowledge on the vocabulary of the North-Eastern Borderlands; the author analyzes the types of words present in the collected material in order to specify whether they are generally attested and well documented, or conversely – less known and only occasionally considered in literature.A large part of the collected material consists of vocabulary well known in Lithuania, and often in the whole area of the North-Eastern Borderlands. These include old expressions of various origin typical of the Eastern Borderlands, richly documented in works devoted to the Polish language of the North-Eastern Borderlands; loans from Lithuanian and Belorussian; or Polish archaic forms, e.g. asystentka ‘maid of honour’, budni ‘usual, ordinary’, fest ‘church fair’, gadzina ‘viper’, hurba ‘snowbank’, karszun ‘hawk’. Another numerous group are newer loanwords from Russian and Lithuanian, popularised in the post-war period, as well as in the recent years along with the changing role of the Lithuanian language, e.g. elektra ‘electric light, electri­city’, awto?awka ‘travelling shop’, balnica ‘hospital’.A small, yet extremely interesting for researchers, part of the lexis is composed of vocabulary not so well known in the North-Eastern Borderlands or in Lithuania, regionally bound (exhibited solely in the examined areas or in two former tightly-knit Polish-speaking areas, with limited frequency (rare words, appearing in various regions, yet seldom recognized, or restricted as far as the chronology is concerned (not attested presently, until now known only from older, pre-war sources, mainly from the works of Halina Turska, e.g. bracienik ‘cousin’, ciuszka ‘blowhole’, czelad? ‘children, offspring’, lun ‘marsh, swamp’, babaczka ‘bow tie’, murawiejnik ‘anthill’, cie?uszutka ‘heiferdim’, ?wiatle? ‘to shine’.A separate group encompasses words previously undocumented in literature, e.g. wieczuruszkowa? ‘to go to soirees, parties in the evening’, including the unknown word-formation variants, e.g. walaniantówka ‘epilepsy’ vs. walentaczka/walantaczka, or the regionally-bound diminutive forms with typical suffixes, today rare, e.g. buteleniatka ‘bottledim’, chustalutka ‘handkerchiefdim’.It is worth emphasizing that certain parts of the described vocabulary might still be commonly used, however the scarcity of extensive lexical research, as well as the lack of a full dictionary of Polish of the North-Eastern Borderlands render it impossible to resolve this question. ??????? ? ??????? ????????? ????? ? ????? ?? ????????-????????-??????????? ??????????? ?????? ???????? ??????? ? ??????? ????????? ?????, ???????????????? ? ????? ?? ????????-????????-??????????? ??????????

    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.

  17. Coupling IR Thermography and BIA to analyse body reaction after one acupuncture session

    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.

    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.

    Cássio Moraes Schambeck

    2015-06-01

    Full Text Available A influência do biodiesel de soja na biodegradação dos hidrocarbonetos monoaromáticos benzeno e tolueno foi estudada sob condições anaeróbias em dois microcosmos montados com água subterrânea sintética, inóculo metanogênico, benzeno, tolueno e biodiesel. Na presença de biodiesel não foi observada biodegradação do benzeno e do tolueno. Com a biodegradação do biodiesel ocorreu a formação de acetato e metano, uso do sulfato e um aumento de 45 vezes no número de bactérias sulfato-redutoras. Esses resultados mostraram que, na mistura com benzeno e tolueno, o biodiesel foi biodegradado tanto sob condições de sulfato-redução quanto metanogênicas e que sua presença estimulou o crescimento da biomassa.

    This paper is devoted to the solution of the bi-fractional differential equation ({sup C}D{sup {alpha}}{sub t}u)(t, x) = {lambda}({sup L}D{sup {beta}}{sub x}u)(t, x) (t>0, -{infinity} 0 and {lambda} {ne} 0, with the initial conditions lim{sub x{yields}}{sub {+-}}{sub {infinity}} u(t,x) = 0 u(0+,x)=g(x). Here ({sup C}D{sup {alpha}}{sub t}u)(t, x) is the partial derivative coinciding with the Caputo fractional derivative for 0 < {alpha} < 1 and with the usual derivative for {alpha} = 1, while ({sup L}D{sup {beta}}{sub x}u)(t, x)) is the Liouville partial fractional derivative ({sup L}D{sup {beta}}{sub t}u)(t, x)) of order {beta} > 0.

  1. Single- and multi-frequency bioelectrical impedance analyses to analyse body composition in maintenance haemodialysis patients: comparison with dual-energy x-ray absorptiometry

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the adequacy of single-frequency (sf-BIA) and multi-frequency bioelectrical impedance analyses (mf-BIA), in comparison with dual-energy x-ray absorptiometry (DXA), to evaluate body composition in maintenance haemodialysis (MHD) patients. Body composition of 27 adult MHD patients (9 f, 18 m), BMI 17.5–34.4 kg m?2, was examined with DXA and BIA, with two different sf-BIA and 1 mf-BIA analysers. Biochemical markers of nutritional status and adequacy of dialytic treatment were also determined. Fat mass (FM) estimated by the different BIA analysers was found to be slightly but significantly higher than FM measured by DXA. In contrast, fat-free mass (FFM) obtained with BIA was found to be slightly but significantly lower than FFM DXA. No significant differences were found between LBM-DXA (that is FFM-DXA minus bone mass) and the different FFM BIA. The lowest mean prediction error versus DXA values was found with sf1BIA. In any case, a close correlation was found between all BIA values and DXA values, particularly for FFM. Furthermore, FFM and LBM results were significantly correlated with serum creatinine, which in MHD patients is an indicator of muscle mass. These results indicate that BIA can be used to evaluate body composition in MHD patients

Foram coletadas, no ano de 2007, amostras cloacais de 51 aves de dez espécies diferentes de cracídeos mantidos em cativeiros no Estado do Rio Grande do Sul. A partir dos swabs, colhidos assepticamente, foi realizado o isolamento e a caracterização bacteriana e o teste de susceptibilidade antimicrobiana dos isolados. Foram identificadas 93 cepas de bactérias. As bactérias mais frequentemente isoladas foram Escherichia coli, Staphylococcus spp. e Streptococcus spp. Todas as amostras foram negativas para o isolamento de Salmonella spp. O resultado do teste de sensibilidade mostrou que dentre as 93 cepas isoladas, todas foram sensíveis apenas ao imipinem. Adicionalmente, os menores percentuais de resistência foram observados frente ao cloranfenicol e ciprofloxacina. Os gêneros e espécies bacterianas com maior percentual de resistência a diferentes antibióticos testados foram Escherichia coli, Serratia marcescens, Staphylococcus aureus e Streptococcus spp. Com os resultados obtidos no presente trabalho, concluí-se, que a população de cracídeos estudada apresenta sua microbiota cloacal composta por vários gêneros e espécies bacterianas e que a multirresistencia pode ser um problema no futuro, uma vez que algumas cepas isoladas mostraram percentuais elevados de resistência a diferente antimicrobianos.Cracids are wildlife Galliformes which inhabits the America's tropical forests. Fifty one cloacal swabs were collected from 10 different species of captive cracids from the Rio Grande do Sul State during 2007. The cloacal swab samples were submitted to bacterial isolation, identification and, subsequently; antimicrobial susceptibility testing. Ninety three bacterial isolates were obtained from the cracid population examined. The most prevalent among the isolates were Escherichia coli, and bacteria from the Staphylococcus and Streptococcus genera. All samples tested in this study were negative for Salmonella spp. The antimicrobial susceptibility tests showed that none of the 93 strains presented resistance to the antimicrobial imipinem. In addition, the lower percentages of resistance were observed against cloranfenicol and ciprofloxacine. The bacteria genus and species with the highest percentage of resistance to the different antimicrobials examined were E. coli, Serratia marcescens, Staphylococcus spp. and Streptococcus spp. In conclusion, the data presented in this article demonstrate that the cloacal microbiota of the reported cracid population is composed of several bacterial genera and species and multi-drug resistance may be a problem for the future, since some strains showed elevated percentage of resistance against several different antimicrobials.

  7. 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 Business intelligence and analytics (BIA initiatives are costly, complex and experience high failure rates. Organizations require effective approaches to evaluate their BIA capabilities in order to develop strategies for their evolution. In this paper, we employ a design science paradigm to develop a comprehensive BIA effectiveness diagnostic (BIAED framework that can be easily operationalized. We propose that a useful BIAED framework must assess the correct factors, should be deployed in the proper process context and acquire the appropriate input from different constituencies within an organization. Drawing on the BIAED framework, we further develop an online diagnostic toolkit that includes a comprehensive survey instrument. We subsequently deploy the diagnostic mechanism within three large organizations in North America (involving over 1500 participants and use the results to inform BIA strategy formulation. Feedback from participating organizations indicates that BIA diagnostic toolkit provides insights that are essential inputs to strategy development. This work addresses a significant research gap in the area of BIA effectiveness assessment.

    Bioimpedance analysis (BIA) is a well-known and tested method for body mass and muscular health assessment. Multi-frequency BIA (mfBIA) equipment now makes it possible to assess a particular muscle as a whole, as well as looking at a muscle at the fiber level. The aim of this study was to test the hypothesis that mfBIA can be used to assess the anatomical, physiological, and metabolic state of skeletal muscles. mfBIA measurements focusing on impedance, resistance, reactance, phase angle, center frequency, membrane capacitance, and both extracellular and intracellular resistance were carried out. Eight healthy human control subjects and three selected cases were examined to demonstrate the extent to which this method may be used clinically, and in relation to training in sport. The electrode setup is shown to affect the mfBIA parameters recorded. Our recommendation is the use of noble metal electrodes in connection with a conductance paste to accommodate the typical BIA frequencies, and to facilitate accurate impedance and resistance measurements. The use of mfBIA parameters, often in conjunction with each other, can be used to reveal indications of contralateral muscle loss, extracellular fluid differences, contracted state, and cell transport/metabolic activity, which relate to muscle performance. Our findings indicate that mfBIA provides a noninvasive, easily measurable and very precise momentary assessment of skeletal muscles.

    2015-10-01

    Clouds are the dominant source of variability in surface solar radiation and uncertainty in its prediction. However, the increasing share of solar energy in the world-wide electric power supply increases the need for accurate solar radiation forecasts. In this work, we present results of a shortest-term global horizontal irradiance (GHI) forecast experiment based on hemispheric sky images. A two month dataset with images from one sky imager and high resolutive GHI measurements from 99 pyranometers distributed over 10 km by 12 km is used for validation. We developed a multi-step model and processed GHI forecasts up to 25 min with an update interval of 15 s. A cloud type classification is used to separate the time series in different cloud scenarios. Overall, the sky imager based forecasts do not outperform the reference persistence forecasts. Nevertheless, we find that analysis and forecast performance depend strongly on the predominant cloud conditions. Especially convective type clouds lead to high temporal and spatial GHI variability. For cumulus cloud conditions, the analysis error is found to be lower than that introduced by a single pyranometer if it is used representatively for the whole area in distances from the camera larger than 1-2 km. Moreover, forecast skill is much higher for these conditions compared to overcast or clear sky situations causing low GHI variability which is easier to predict by persistence. In order to generalize the cloud-induced forecast error, we identify a variability threshold indicating conditions with positive forecast skill.

    High penetration renewable integration studies need high quality solar power data with spatial-temporal correlations that are representative of a real system. This paper will summarize the research relating sequential point-source sub-hour global horizontal irradiance (GHI) values to static, spatially distributed GHI values. This research led to the development of an algorithm for generating coherent sub-hour datasets that span distances ranging from 10 km to 4,000 km. The algorithm, in brief, generates synthetic GHI values at an interval of one-minute, for a specific location, using SUNY/Clean Power Research, satellite-derived, hourly irradiance values for the nearest grid cell to that location and grid cells within 40 km.

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.

  10. Multi-frequency bioimpedance in equine muscle assessment

    DEFF Research Database (Denmark)

    2015-01-01

    Multi-frequency BIA (mfBIA) equipment has been shown to be a non-invasive and reliable method to assess a muscle as a whole or at fibre level. In the equine world this may be the future method of assessment of training condition or of muscle injury. The aim of this study was to test if mfBIA reliably can be used to assess the condition of a horse's muscles in connection with health assessment, injury and both training and re-training. mfBIA measurements was carried out on 10 'hobby' horses and 5 selected cases with known anamnesis. Impedance, resistance, reactance, phase angle, centre frequency, membrane capacitance and both extracellular and intracellular resistance were measured. Platinum electrodes in connection with a conductance paste were used to accommodate the typical BIA frequencies and to facilitate accurate measurements. Use of mfBIA data to look into the effects of myofascial release treatment was also demonstrated. Our findings indicate that mfBIA provides a non-invasive, easily measurable and very precise assessment of the state of muscles in horses. This study also shows the potential of mfBIA as a diagnostic tool as well as a tool to monitor effects of treatment e.g. myofascial release therapy and metabolic diseases, respectively.

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

    Science.gov (United States)

    Nuijten, M J C; Mittendorf, T; Persson, U

    2011-06-01

    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

    Yehia Eissa

    2015-07-01

    Full Text Available HelioClim-3 (HC3 is a database providing time series of the surface downwelling solar irradiance that are computed from images of the Meteosat satellites. This paper presents the validation results of the hourly global horizontal irradiance (GHI and direct normal irradiance (DNI, i.e., beam irradiance at normal incidence, of versions four and five of HC3 at seven Egyptian sites. The validation is performed for all-sky conditions, as well as cloud-free conditions. Both versions of HC3 provide similar performances whatever the conditions. Another comparison is made with the estimates provided by the McClear database that is restricted to cloud-free conditions. All databases capture well the temporal variability of the GHI in all conditions, McClear being superior for cloud-free cases. In cloud-free conditions for the GHI, the relative root mean square error (RMSE are fairly similar, ranging from 6% to 15%; both HC3 databases exhibit a smaller bias than McClear. McClear offers an overall better performance for the cloud-free DNI estimates. For all-sky conditions, the relative RMSE for GHI ranges from 10% to 22%, except one station, while, for the DNI, the results are not so good for the two stations with DNI measurements.

    2008-12-01

    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.

  8. The value of bioelectrical impedance analysis and phase angle in the evaluation of malnutrition and quality of life in cancer patients-a comprehensive review.

    Science.gov (United States)

    Grundmann, O; Yoon, S L; Williams, J J

    2015-12-01

    Bioelectrical impedance analysis (BIA) and especially its derived parameter phase angle have been widely used in different populations. The variability of BIA measures has often been cited as a major limitation for its clinical use in evaluating nutritional status and overall health of patients. Cancer patients often present with malnourishment and cachexia, which complicate the course of treatment and affect outcomes. PubMed, CINAHL, EBSCO and Cochrane Library have been searched for relevant publications in English for BIA in cancer patients. Out of 197 total results, 27 original research articles related to BIA measures in cancer patients were included in this review. Studies indicate that the use of BIA and phase angle measures can benefit in the clinical management of cancer patients in multiple ways: in the prevention; diagnosis; prognosis; and outcomes related to treatments that affect nutritional and overall health status. Phase angle and fat-free mass measures were most commonly evaluated and correlated with nutritional status and survival rate. One limitation of BIA measures is the high interpatient variability which requires careful interpretation of results in the context of the individual patient rather than comparison with population data. The BIA and phase angle provide practitioners for the evaluation of nutritional and overall health status in cancer patients with a convenient and non-invasive technique and should be encouraged.

    2013-01-01

    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.

    DEFF Research Database (Denmark)

    Kyle, Ursula G; Bosaeus, Ingvar

    2004-01-01

    The use of bioelectrical impedance analysis (BIA) is widespread both in healthy subjects and patients, but suffers from a lack of standardized method and quality control procedures. BIA allows the determination of the fat-free mass (FFM) and total body water (TBW) in subjects without significant fluid and electrolyte abnormalities, when using appropriate population, age or pathology-specific BIA equations and established procedures. Published BIA equations validated against a reference method in a sufficiently large number of subjects are presented and ranked according to the standard error of the estimate. The determination of changes in body cell mass (BCM), extra cellular (ECW) and intra cellular water (ICW) requires further research using a valid model that guarantees that ECW changes do not corrupt the ICW. The use of segmental-BIA, multifrequency BIA, or bioelectrical spectroscopy in altered hydration states also requires further research. ESPEN guidelines for the clinical use of BIA measurements are described in a paper to appear soon in Clinical Nutrition.

  11. Modeling of global horizontal irradiance in the United Arab Emirates with artificial neural networks

    International Nuclear Information System (INIS)

    This paper employs ANN (Artificial Neural Network) models to estimate GHI (global horizontal irradiance) for three major cities in the UAE (United Arab Emirates), namely Abu Dhabi, Dubai and Al-Ain. City data are then used to develop a comprehensive global GHI model for other nearby locations in the UAE. The ANN models use MLP (Multi-Layer Perceptron) and RBF (Radial Basis Function) techniques with comprehensive training algorithms, architectures, and different combinations of inputs. The UAE models are tested and validated against individual city models and data available from the UAE Solar Atlas with good agreement as attested by the computed statistical error parameters. The optimal ANN model is MLP-based and requires four mean daily weather parameters; namely, maximum temperature, wind speed, sunshine hours, and relative humidity. The computed statistical error parameters for the optimal MLP-ANN model in relation to the measured three-cities mean data (referred to as UAE data) are MBE (mean bias error) = −0.0003 kWh/m2, RMSE = 0.179 kWh/m2, R2 = 99%, NSE (Nash-Sutcliffe model Efficiency coefficient) = 99%, and t-statistic = 0.005 at 5% significance level. Results prove the suitability of the ANN models for estimating the monthly mean daily GHI in different locations of the UAE. - Highlights: • ANN prediction models for the GHI (global horizontal irradiance) in the UAE. • Models used to estimate the potential of global solar radiation for UAE cities. • Data from the UAE Solar Atlas are used to validate developed ANN models. • ANN models are more efficient than regression models in predicting GHI

    Saputri, Azizah Anugrahwati; Noviyanti, Lienda; Soleh, Achmad Zanbar

    2015-12-01

    Operational risk is inherent in bank activities. To cover this risk a bank reserves a fund called as capital. Often a bank uses Basic Indicator approach (BIA), Standardized Approach (SA), or Advanced Measurement Approach (AMA) for estimating the capital amount. BIA and SA are less-objective in comparison to AMA, since BIA and SA use non-actual loss data while AMA use the actual one. In this research, we define the capital as an OpVaR (i.e. the worst loss at a given confidence level) which will be estimated by Peak Over Threshold Method.

    2015-09-29

    This study aimed at comparing BIA and DXA results in assessing body composition in young adults depending on their physical activity level. Eighty healthy 19-30 years old subjects were enrolled and their body composition (Fat Mass and Fat-Free Mass) was assessed by dual-energy X-ray absorptiometry (DXA) and by a newly developed Bioelectrical Impedance Analyzer (BIA - Tanita MC780). A seven-day physical activity level was assessed using a 3-axial accelerometer. DXA-FM% and BIA-FM% were correlated (pFFM and BIA FFM were correlated (pFFM were highly correlated in both boys and girls regardless of the physical activity level. Compared with DXA scans, newly developed bioelectrical impedance analyzers provide satisfactory fat mass and lean mass measures in healthy young women and men, despite their physical activity level.

  10. The Estimation of the Fat Free Mass Index in Athletes.

    Directory of Open Access Journals (Sweden)

    Thomas J. Pujol,

    2012-09-01

    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.

  11. Changes in body composition during weight loss in obese subjects in the NUGENOB study: Comparison of bioelectrical impedance vs. dual-energy X-ray absorptiometry

    DEFF Research Database (Denmark)

    Verdich, Camilla; Barbe, P

    2011-01-01

    AIM: We studied the accuracy of bioelectrical impedance analysis (BIA) to assess changes in body composition during moderate weight loss in obese subjects. METHODS: Estimates of changes in fat mass (FM) and fat-free mass (FFM) by BIA were compared with those by dual-energy X-ray absorptiometry (DXA) as the reference method during a 10-week standardized weight-loss intervention. In obese women (age: 20-50years, mean BMI: 33.8kg/m(2)) participating in a European multicentre trial (nutrient-gene interactions in human obesity [NUGENOB]), body composition was assessed by BIA (Bodystat QuadScan 4000) and DXA (Lunar DPX-IQ at two centres, Hologic QDR 2000 at another centre) at baseline (n=131) and at week 10 (n=105) after a mean weight loss of -5.7kg. RESULTS: At baseline, BIA significantly overestimated FFM and underestimated FM (by 1-3kg on average) compared with DXA, and the limits of agreement were wide (mean±7-8.5kg). For body-composition changes, although biases were generally non-significant, the limits of agreement were also wide (mean±3.7-4.6kg). An FFM prediction equation for BIA data was developed in subjects scanned with Lunar instruments and cross-validated in an independent sample of 31 obese women undergoing similar weight loss. However, no major improvement in limits of agreement was found. CONCLUSION: During moderate diet-induced weight loss, the use of BIA leads to estimates of changes in body composition at the individual level that can differ substantially from those assessed by DXA, indicating that BIA and DXA cannot be used interchangeably. However, BIA in this context may be used for assessing changes in body composition at group level.

    2015-09-01

    Full Text Available Current bioelectric impedance analysis (BIA systems are often large, cumbersome devices which require strict electrode placement on the user, thus inhibiting mobile capabilities. In this work, we developed a handheld BIA device that measures impedance from multiple frequencies (5 kHz~200 kHz with four contact electrodes and evaluated the BIA device against standard body composition analysis systems: a dual-energy X-ray absorptiometry (DXA system (GE Lunar Prodigy, GE Healthcare, Buckinghamshire, UK and a whole-body BIA system (InBody S10, InBody, Co. Ltd, Seoul, Korea. In the study, 568 healthy participants, varying widely in body mass index, age, and gender, were recruited at two research centers: the Samsung Medical Center (SMC in South Korea and the Pennington Biomedical Research Center (PBRC in the United States. From the measured impedance data, we analyzed individual body fat and skeletal muscle mass by applying linear regression analysis against target reference data. Results indicated strong correlations of impedance measurements between the prototype pathways and corresponding InBody S10 electrical pathways (R = 0.93, p < 0.0001. Additionally, body fat estimates from DXA did not yield significant differences (p > 0.728 (paired t-test, DXA mean body fat 29.45 ± 10.77 kg, estimated body fat 29.52 ± 12.53 kg. Thus, this portable BIA system shows a promising ability to estimate an individual’s body composition that is comparable to large stationary BIA systems.

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)

    Full Text Available Two hundred and fifty seven male Caucasian ultraendurance athletes were recruited, pre-race, before different swimming, cycling, running and triathlon races. Fat mass and skeletal muscle mass were estimated using bioelectrical impedance analysis (BIA and anthropometric methods in order to investigate whether the use of BIA or anthropometry would be useful under field conditions. Total body fat estimated using BIA was significantly high (P Se reclutaron a 257 hombres caucasianos que eran atletas de alto rendimiento, antes de competir en diferentes pruebas triatlón de natación, ciclismo y carrera. Se estimaron la masa grasa y la masa de músculo esquelético utilizando un análisis de impedancia bioeléctrica (BIA y métodos antropométricos con el fin de investigar si el uso de BIA o de la antropometría sería útil en tales condiciones de campo. La grasa corporal total estimada por BIA fue significativamente mayor en comparación con la antropometría (P < 0,001. Cuando se compararon los resultados entre BIA y antropometría, se encontraron niveles de concordancia bajos a moderados.

    Full Text Available Abstract Background Shortages of health workers are obstacles to utilising global health initiative (GHI funds effectively in Africa. This paper reports and analyses two countries' health workforce responses during a period of large increases in GHI funds. Methods Health facility record reviews were conducted in 52 facilities in Malawi and 39 facilities in Zambia in 2006/07 and 2008; quarterly totals from the last quarter of 2005 to the first quarter of 2008 inclusive in Malawi; and annual totals for 2004 to 2007 inclusive in Zambia. Topic-guided interviews were conducted with facility and district managers in both countries, and with health workers in Malawi. Results Facility data confirm significant scale-up in HIV/AIDS service delivery in both countries. In Malawi, this was supported by a large increase in lower trained cadres and only a modest increase in clinical staff numbers. Routine outpatient workload fell in urban facilities, in rural health centres and in facilities not providing antiretroviral treatment (ART, while it increased at district hospitals and in facilities providing ART. In Zambia, total staff and clinical staff numbers stagnated between 2004 and 2007. In rural areas, outpatient workload, which was higher than at urban facilities, increased further. Key informants described the effects of increased workloads in both countries and attributed staff migration from public health facilities to non-government facilities in Zambia to PEPFAR. Conclusions Malawi, which received large levels of GHI funding from only the Global Fund, managed to increase facility staff across all levels of the health system: urban, district and rural health facilities, supported by task-shifting to lower trained staff. The more complex GHI arena in Zambia, where both Global Fund and PEPFAR provided large levels of support, may have undermined a coordinated national workforce response to addressing health worker shortages, leading to a less effective response in rural areas.

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

    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.

Twenty-two portion control practices were rated in terms of their frequency of use from ‘never’ to ‘very often’ by a representative sample of 1012 consumers from the island of Ireland. Three factors were extracted and named: measurement-strategy scale, eating-strategy scale, and purchasing-strategy scale. The eating-strategy scale score was the highest, while the measurement-strategy scale carried the lowest frequency score. For each strategy scale score, the strongest predictor was GHI, followed by gender. Having higher GHI and being female were independently associated with more frequent portion control. Both the eating-strategy scale score and the purchasing-strategy scale score were negatively associated with pizza portion size consumption estimates. In conclusion, while this study demonstrates that the reported use of portion control practices is low, the findings provide preliminary evidence for their validity. Further studies are needed to explore how portion control practices are used in different kinds of portion size decisions and what their contribution is to the intake of food over an extended period of time

  11. Surface Radiation from GOES: A Physical Approach; Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Habte, A.; Sengupta, M.; Wilcox, S.

    2012-09-01

    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.

  15. V-dotO2max prediction from multi-frequency bioelectrical impedance analysis

    International Nuclear Information System (INIS)

    Bioelectrical impedance analysis (BIA) has been shown to be highly related to skeletal muscle mass and blood volume, both of which are important determinants of maximal oxygen uptake (V-dotO2max). The aim of the present study was therefore to investigate the ability of whole-body and segmental multi-frequency BIA to improve current nonexercise V-dotO2max prediction models. Data for V-dotO2max (mL min?1), anthropometry, self-reported physical activity (PA-R) and BIA were collected in 115 men and women. Multiple linear regression analysis (MLR) was used to develop the most parsimonious prediction model. Segmental BIA was not superior to whole-body measurements. Correlation coefficients between V-dotO2max and resistance indices were significantly higher at 500 kHz compared to 50 kHz (p 2max (r = 0.89). After adjusting for age, gender and PA-R, MLR revealed that the inclusion of intracellular resistance index was slightly, but significantly (p 2max (?1). In short, whole-body BIA marginally improves the accuracy of nonexercise V-dotO2max prediction models and its advantage is most pronounced in individuals with particularly low V-dotO2max

    There are a number of differences between the body composition of children and adults. Body composition measurements in children are inherently challenging, because of the rapid growth-related changes in height, weight, fat-free mass (FFM) and fat mass (FM), but they are fundamental for the quality of the clinical follow-up. All body composition measurements for clinical use are 'indirect' methods based on assumptions that do not hold true in all situations or subjects. The clinician must primarily rely on two-compartment models (that is, FM and FFM) for routine determination of body composition of children. Bioelectrical impedance analysis (BIA) is promising as a bedside method, because of its low cost and ease of use. This paper gives an overview of the differences in body composition between adults and children in order to understand and appreciate the difference in body composition during growth. It further discusses the use and limitations of BIA/bioelectrical spectroscopy (BIA/BIS) in children. Single-frequency and multi-frequency BIA equations must be refined to better reflect the body composition of children of specific ethnicities and ages but will require development and cross-validation. In conclusion, recent studies suggest that BIA-derived body composition and phase angle measurements are valuable to assess nutritional status and growth in children, and may be useful to determine baseline measurements at hospital admission, and to monitor progress of nutrition treatment or change in nutritional status during hospitalization.

    This paper describes a model for predicting hemoglobin (Hb) by using bioelectrical impedance analysis (BIA) in dengue patients in the Hospital Universiti Kebangsaan Malaysia (HUKM). Bioelectrical impedance measurements were conducted on 83 (47 males and 36 females) serologically confirmed dengue fever (DF) and dengue hemorrhagic fever (DHF) patients during their hospitalization. The predictive equation for Hb was derived using multivariate analysis. We investigated all the parameters in BIA, patients' symptom and demographic data. In this developed model, four predictors (reactance (XC), sex, weight and vomiting) were found to be the best predictive factors for modeling Hb in dengue patients. However, the model can only explain approximately 42% of the variation in Hb status, thus single frequency bio-impedance stand-alone technique is insufficient to monitor Hb for the DF and DHF patients. Further investigation using multi-frequency BIA is recommended in modeling Hb to achieve the most parsimonious model. PMID:15253113

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.

    Full Text Available We evaluated the concordance between visceral fat area (VFA estimated by bioelectrical impedance analysis (BIA or computed tomography (CT in Korean subjects with a wide range in age and body mass index (BMI. In 1006 individuals (mean age 55.2 ± 11.8 (19–87 years, mean BMI 26.0 ± 3.5 (17–46 kg/m2, 48.9% men, VFA quantified by CT was compared with VFA using multifrequency BIA machines within 15 days. Concordance rates were compared by age or BMI using correlation analysis, Bland-Altman plots, and intraclass correlation coefficient (ICC. Using BIA data, we established a regression formula to reflect CT-VFA. The mean VFAs by CT and BIA were 131.9 ± 57.3 cm2 and 110.5 ± 33.9 cm2, respectively (r = 0.605, p < 0.001. The mean difference was 21.4 ± 45.6 cm2, tending to increase with BMI. In women with BMI <25 kg/m2 or age <50 years, the VFAs by BIA were similar to those by CT (ICC = 0.496 in BMI <25 kg/m2 and ICC = 0.638 in age <50 years. However, the difference was greater in men with BMI ?25 kg/m2 or age ?50 years. Applying our formula, the difference between estimations decreased to 0.2 ± 38.2cm2. VFA estimated by BIA correlated well with that by CT, but a more accurate formula is needed to match CT data, particularly in older men or subjects with a high BMI.

    We aimed to assess the agreement of a commercially available bioelectrical impedance analysis (BIA) device in measuring changes in fat, lean and bone mass over a 10-week lifestyle intervention, with dual energy X-ray absorptiometry (DXA) as reference. A sample of 136 volunteers (18-66 years) underwent a physical activity intervention to enhance lean mass and reduce fat mass. BIA (Tanita BC545) and DXA (Hologic Explorer) measures of whole-body composition were taken at baseline and at the end of the intervention. After an average of 74 ± 18 days intervention, DXA showed significant changes in 2 of 3 outcome variables: reduced fat mass of 0.802 ± 1.092 kg (P < 0.001), increased lean mass of 0.477 ± 0.966 kg (P < 0.001); minor non-significant increase of 0.007 ± 0.041 kg of bone mass (P = 0.052). The respective changes in BIA measures were a significant reduction of 0.486 ± 1.539 kg fat (P < 0.001), but non-significant increases of 0.084 ± 1.201 kg lean mass (P = 0.425), and 0.014 ± 0.091 kg bone (P = 0.074). Significant, but moderately weak, correlations were seen in absolute mass changes between DXA and BIA: 0.511 (fat), 0.362 (lean) and 0.172 (bone). Compared to DXA, BIA demonstrated mediocre agreement to changes in fat mass, but poor agreement to lean mass changes. BIA significantly underestimated the magnitude of changes in fat and lean mass compared to DXA. PMID:26451461

    Benzylisoquinoline alkaloids (BIAs) are a family of ?2500 alkaloids with both potential and realized pharmaceutical value, including most notably the opiates such as codeine and morphine. Only a few BIAs accumulate readily in plants, which limits the pharmaceutical potential of the family. Shifting BIA production to microbial sources could provide a scalable and flexible source of these compounds in the future. This review details the current status of microbial BIA synthesis and derivatization, including rapid developments in the past 6 months culminating in the synthesis of opioids from glucose in a microbial host.

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

    Science.gov (United States)

    Chirvi, Sajal

    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.

    Biotinyl-m-[125I]iodoanilide (BIA) was synthesized by coupling biotin to m-[125I]iodoaniline via a mixed anhydride reaction. m-[125I]Iodoaniline was produced from the tin precursor, which was prepared using a palladium catalyzed reaction of hexabutylditin with m-bromoaniline. The radioiodinated BIA derivative is characterized by a stable amide and/or intact ureido group on the biotin molecule, it may thus be a useful carrier for targeting radionuclides to avidin-conjugated antibodies previously localized on tumors.

    Full Text Available O trabalho teve, como objetivo principal, verificar se a antropometria (ANT) e a impedância bioelétrica (BIA) fornecem resultados concordantes com os obtidos pela absortiometria de raios-X de dupla energia (DXA), quanto à massa (MG) e à porcentagem de gordura (%GC), à massa livre de gordura corporal [...] (MLG) e ao índice de MLG (IMLG= MLG/estatura²), em indivíduos adultos (³ 50 anos), do sexo masculino, sadios (n=23) e em pacientes com doença pulmonar obstrutiva crônica (DPOC) (n=24). As comparações entre as técnicas de composição do corpo foram feitas utilizando ANOVA por medidas repetidas; para análise de concordância, utilizou-se o procedimento de Bland & Altman. Resultados e Conclusões: 1) valores obtidos no grupo sadio foram significantemente diferentes dos observados no grupo com DPOC; 2) não foram observadas diferenças significantes, nos indivíduos sadios, entre DXA ´ BIA e entre DXA ´ ANT; em DPOC, a comparação entre DXA ´ BIA revelou, para BIA, valores estatisticamente maiores para MG e %GC e menores para MLG e IMLG; na comparação DXA ´ ANT, não houve diferenças significantes entre as variáveis; 3) a aplicação do teste de Bland & Altman, em ambos os grupos, mostrou falta de concordância na comparação da BIA com DXA e, também, da ANT com DXA; verificou-se, também, superestimação da gordura corporal e subestimação da MLG pela BIA, em relação à DXA. Abstract in english Comparative analysis of body composition assessment methods in healthy men and in chronic obstructive pulmonary disease patients: anthropometry, bioelectrical impedance and dual-energy X-ray absorptiometry. The aim of this study was to examine the agreement between the results of body fat (BF and BF [...] %), fat-free mass (FFM) and FFM index (FFMI= FFM/height²) as estimated by skinfold anthropometry (ANT), bioelectrical impedance (BIA) and dual-energy X-ray absorptiometry (DXA) in two groups of men (³ 50 y), one comprising healthy individuals (n=23) and the other, patients with chronic obstructive pulmonary disease (COPD) (n=24). Comparisons between body composition techniques were done by repeated measures ANOVA; the Bland & Altman procedure was used to analyse agreement. Results and Conclusions: 1) comparison between healthy and COPD groups showed significant differences between all studied variables; 2) in the healthy group, values for BF, BF% , FFM and FFMI were not significantly different when BIA or ANT was compared to DXA; however, in COPD, values for BF and BF% were significantly higher and for FFM and FFMI significantly lower when BIA was compared to DXA; in contrast, no differences were shown between values for these variables when ANT was compared with DXA; 3) Bland & Altman test, in both groups, showed no agreement between BIA and DXA and between ANT and DXA; it was also shown that body fat was overestimated and fat free mass underestimated by BIA in relation to DXA.

    Full Text Available O presente estudo tem como objetivos: a verificar a concordância entre os métodos da impedância bioelétrica (BIA e da absortometria radiológica de dupla energia (DXA para a estimativa da massa muscular esquelética (MME; e b analisar o poder preditivo de variáveis antropométricas e da BIA para a predição da MME em idosas. Foram avaliadas 120 mulheres (60 a 81 anos, residentes na região Sul do Brasil. Mensuraram-se as variáveis antropométricas (massa corporal e estatura; a resistência e hidratação dos tecidos livres de gordura foram medidas pela técnica da BIA tetrapolar (Biodinamics - BF-310, e pela DXA de corpo inteiro (Lunar Prodigy DF + 14319 Radiation e software 7.52.002 DPX-L. A diferença entre os métodos foi verificada pelo teste t pareado, análise dos resíduos e o coeficiente de correlação. O valor preditivo das variáveis antropométricas e de BIA foi verificado pela regressão linear múltipla, adotando nível de significância de p 0,01. Observou-se que a BIA subestimou em média 0,8kg (IC95%: -3,7; 2,0kg a MME, quando comparada com a DXA. Foi observada alta correlação entre os métodos (r² = 0,75; p The objectives of the present study were: a to determine the agreement between bioelectrical impedance analysis (BIA and dual-energy X-ray absorptiometry (DXA for the estimation of skeletal muscle mass (SMM, and b to analyze the predictive power of anthropometric variables and BIA for the prediction of SMM in elderly women. A total of 120 women (60 to 81 years, living in the southern region of Brazil, were studied. Anthropometric variables (body weight and height were measured. Resistance and hydration of fat-free tissues were measured by tetrapolar BIA (Biodynamics, BF-310 and by whole-body DXA (Lunar Prodigy DF + 14319 Radiation and DPX-L software, version 7.52.002. Differences between methods were determined using the paired t-test, analysis of residuals and correlation coefficient. The predictive value of the anthropometric variables and BIA was evaluated by multiple linear regression, adopting a level of significance of p < 0.05. No significant difference in the estimation of SMM was observed between methods (p < 0.01. BIA underestimated SMM in mean of 0.8 kg (95%CI: -3.7; 2.0 kg when compared to DXA. Correlation between methods was high (r² = 0.75; p < 0.01. Regression analysis demonstrated that the ratio between the square of height and resistance (HEIGHT²/R explained 80% of the variation in SMM when adjusted to body weight and age, regardless of body fat, lean tissue hydration or body mass index. Thus, the BIA equation tested here is a valid tool for the estimation of SMM in elderly women and its value is best predicted by the regression model including HEIGHT²/R adjusted to body weight and age.

  14. Source apportionment of elevated wintertime PAHs by compound-specific radiocarbon analysis

    Full Text Available Natural abundance radiocarbon analysis facilitates distinct source apportionment between contemporary biomass/biofuel (14C "alive" versus fossil fuel (14C "dead" combustion. Here, the first compound-specific radiocarbon analysis (CSRA of atmospheric polycylic aromatic hydrocarbons (PAHs was demonstrated for a set of samples collected in Lycksele, Sweden a small town with frequent episodes of severe atmospheric pollution in the winter. Renewed interest in residential wood combustion means than this type of seasonal pollution is of increasing concern in many areas. Five individual/paired PAH isolates from three pooled fortnight-long filter collections were analyzed by CSRA: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene plus benzo[ghi]perylene; phenanthrene was the only compound also analyzed in the gas phase. The measured ?14C for PAHs spanned from ?138.3‰ to 58.0‰. A simple isotopic mass balance model was applied to estimate the fraction biomass (fbiomass contribution that was constrained to a range of 71% for indeno[cd]pyrene+benzo[ghi]perylene to 87% for the gas phase phenanthrene and particulate fluoranthene, respectively. Indeno[cd]pyrene plus benzo[ghi]perylene, known to be enhanced in gasoline-powered motor vehicle exhaust compared to diesel exhaust, had the lowest contribution of biomass combustion of the measured PAHs by 9%. The total organic carbon (TOC, defined as carbon remaining after removal of inorganic carbon fbiomass was estimated to be 77%, which falls within the range for PAHs. This CSRA data of atmospheric PAHs demonstrate the non-uniformity of biomass combustion contribution to different PAHs even in a location with limited local emission sources and illustrates that regulatory efforts would not evenly reduce all PAHs.

  15. Developing and testing solar irradiance forecasting techniques in the Hawaiian Islands region

    2014-12-01

    Irradiance variability, primarily driven by cloud formation and advection, can be problematic in the state of Hawaíi, because of the high penetration of distributed solar and the small scale of the island electrical grids. The Hawaíi Natural Energy Institute (HNEI) is developing an operational system in order to research and test new techniques to generate solar forecasts for the Hawaiian Islands. The operational system comprises the following three components.(i) A ground-observation-based advection model, using sky imagers and a ceilometer located at the University of Hawaíi at M?noa. Every 10 minutes (during daylight hours), this component generates a high-resolution 1 hour Global Horizontal Irradiance (GHI) prediction for a region that is within ~15 km of the instrumentation. (ii) A satellite-image-based advection model, using Geostationary Operational Environmental Satellite (GOES) imagery and the Heliosat-II method. Every 30 minutes (during daylight hours), this component generates a 1 km resolution, 6 hour GHI prediction for the entire Hawaiian Archipelago. (iii) A coupled ocean-atmosphere model, using the Regional Ocean Modeling System (ROMS) model and the Weather Research and Forecasting (WRF) model, including newly available microphysics, shallow convection parameterization, and radiative transfer model options. Nightly, this component generates 48 hour GHI, Direct Normal Irradiance (DNI), and Diffuse Horizontal Irradiance (DHI) predictions for (a) a 10 km resolution domain covering the full Hawaiian Archipelago and (b) a nested 2 km resolution domain covering the islands of Maui, Óahu, and Hawaíi. We discuss the development and validation of the system, and the scales of forecasting accuracy for each component. We also examine the impact of the coupled model on the simulations of surface flux processeses and ocean-atmosphere feedbacks, both of which influence the prediction of regional cloud properties.

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

    Directory of Open Access Journals (Sweden)

    Allen Barnett

    2012-03-01

    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.

    Recent healthcare reform in Turkey aims at achieving universal coverage with the introduction of General Health Insurance (GHI). As part of GHI, the state assumes the provision of health insurance coverage to those unable to afford the public health insurance premiums conditional on a means-testing procedure where the official threshold is set as one-third of the gross minimum wage. This article aims at exploring in Turkey the prevalence of non-take up of means-tested health insurance for the poor and the consequent financial burdens for those poor segments outside the coverage. Based upon Statistics of Income and Living Conditions micro data, the non-take-up rate is estimated to be around 44%, where the prevalence of non-take-up is lower yet still high, i.e. around 30%, for households with very low incomes as well as those with elderly or ill members. The results from a separate health expenditure survey on urban poor, which is specifically designed and implemented by the authors, reveal that poor households without health insurance coverage are faced with significant out-of-pocket expenditures. About 5% of those households without coverage were found to have inpatient expenditures that exceeded 20% of their annual disposable household income. Also, among the households without coverage but with at least one inpatient visit over the last two years, the median expenditure was reported as high as 8% of the annual household income as opposed to 0% median value for those with GHI. The results highlight that a large proportion of poor population still lacks public health insurance despite the overarching aim of universal coverage. PMID:25689667

  18. Artificial neural network based daily local forecasting for global solar radiation

    International Nuclear Information System (INIS)

    Highlights: • A new method for local forecasting of daily global solar radiation is proposed. • The model combines the artificial neural networks and the special modelling. • The model exploits weather forecasts provided by specialized agency. • The model’s forecasts were compared to measured data for two locations. • The developed model estimates daily solar radiation with satisfactory accuracy. - Abstract: When a part of the power is generated by grid connected photovoltaic installations, an effective global solar irradiation (GSI) forecasting tool becomes a must to ensure the quality and the security of the electrical grid. GSI forecasts allow the quantification of generated photovoltaic (PV) power and helps electrical grid operators anticipate problems related to the nature of PV power and the planning for adequate solutions and decisions. In this study, a new methodology for local forecasting of daily global horizontal irradiance (GHI) is proposed. This methodology is a combination of spatial modelling and artificial neural networks (ANNs) techniques. An ANN based model is developed to predict the local GHI based on daily weather forecasts provided by the US National Oceanic and Atmospheric Administration (NOAA) for four neighbouring locations. The methodology was tested for two locations; Le Bourget du Lac (45°38′44″N, 5°51′33″E), which is located in the French Alps and Cadarache (43°42′28″N, 05°46′31″E), which is located in the south of France. The model’s forecasts were compared to measured data for the two locations and validation results indicate that the ANN-based method presented in this study can estimate daily GHI with satisfactory accuracy

    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.

    2012-08-01

    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.

  9. Change in fat-free mass assessed by bioelectrical impedance, total body potassium and dual energy X-ray absorptiometry during prolonged weight loss

    DEFF Research Database (Denmark)

    Hendel, H W; Gotfredsen, A; Højgaard, L; Andersen, T; Hilsted, Jannik

    1996-01-01

    A total of 16 obese women (body mass index (BMI) 30-43 kg m(-2)) participated in a weight reduction study. Before and after a weight loss of 11.7 +/- 7.4 kg (mean +/- SD), body composition was assessed by dual energy X-ray absorptiometry (DXA), and total body potassium counting (TBK). These...... measurements were compared with bioimpedance analysis (BIA) by applying 11 predictive BIA equations published in the literature. Predictive equations for the present study population were developed, with the use of fat-free mass (FFM) as assessed by TBK and DXA as references in multiple regression analysis....... The results of the BIA equations varied widely; FFM was generally overestimated by BIA as compared with DXA and TBK before and after weight loss. During weight loss, the FFM did not change, as estimated by DXA (1.3 +/- 2.3 kg, p > 0.05) and TBK (0.9 +/- 2.9 kg, p > 0.05). The recorded change in...

    2014-07-01

    Full Text Available Hematopoietic stem cell transplantation (HSCT is widely used in the treatment of malignant and autoimmune diseases. Various complications often develop during the post-transplantation period that can significantly impair the clinical outcomes, so the ability to predict therisk of severe complications is of great practical importance. Predictive value of some anthropometric indices and bioimpedance analysis(BIA measured before conditioning to assess the risks of serious complications and graft hypofunction in the early post-transplant period(100 days were analyzed. Anthropometry and BIA used in a comprehensive assessment of nutritional status in order to optimize the nutritional support of these patients. 101 patients were examined before conditioning and at different times during the early post-transplant period: 50 children (5–17 years of age were examined using BIA and anthropometry, 61 children (6 months – 4 years of age – using only anthropometry without BIA due to age restrictions. The prognostic value of the phase angle (FA, ratio of the active cell mass to lean body mass (ACM/LBM and shoulder muscle circumference (SMC was shown. Thus, in patients with FA ? 4, ACM/LBM < 0.45 and SMC ? 10th percentile before conditioning risk of severe complications during early post-transplant period was significantly higher (p < 0.05. Also, in patients with FA ? 4 and ACM/LBM < 0.45 a significantly higher risk of graft hypofunction developing was observed (p < 0.05.

  19. 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)

    Liu Li

    2012-09-01

    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

  20. Validity of leg-to-leg bioelectrical impedance measurement in highly active women.

    Civar, Selma; Aktop, Abdurrahman; Tercan, Evren; Ozdol, Yeliz; Ozer, Kamil

    2006-05-01

    The aim of this study was to compare the validity of the leg-to-leg bioelectrical impedance analysis (BIA) method with that of anthropometry using hydrostatic weighing (HW) as the criterion test. A secondary objective was to cross-validate previously developed anthropometric regression equations as well as to develop a new regression equation formula based on the anthropometric data collected in this study. Three methods for assessing body composition (HW, BIA, and anthropometric) were applied to 60 women university athletes. The means and standard deviations of age, weight, height, and body mass index (BMI) of athletes were as follows: age, 20.70 +/- 1.43; weight, 56.19 +/- 7.83 kg; height, 163.33 +/- 6.11 cm; BMI, 21.01 +/- 2.63 kg x m(-2). Leg-to-leg BIA (11.82 +/- 2.39) has shown no statistical difference between percentage body fat determined by HW (11.63 +/- 2.42%) in highly active women (p > 0.05). This result suggests that the leg-to-leg BIA and HW methods were somewhat interchangeable in highly active women (R = 0.667; standard error of estimate [SEE] = 1.81). As a result of all cross-validation analyses, anthropometric and BIA plus anthropometric results have generally produced lower regression coefficients and higher SEEs for highly active women between the ages of 18 and 25 years. The regression coefficients (0.903, 0.926) and SEE (1.08, 0.96) for the new regression formulas developed from this study were better than the all the other formulas used in this study.

    2015-05-01

    In the fall of 2010, a multiyear pilot energy efficiency retrofit project was undertaken by Greenbelt Homes, Inc, (GHI) a 1,566 home cooperative of circa 1930 and 1940 homes in Greenbelt, Maryland. GHI established this pilot project to serve as a basis for decision making for the rollout of a decade-long community-wide upgrade program that will incorporate energy efficiency improvements to the building envelope and mechanical equipment. It presents a unique opportunity to evaluate and prioritize the wide-range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project. Addressing the complex interactions between benefits, trade-offs, construction methods, project management implications, realistic upfront costs, financing, and other considerations, serves as a case study for energy retrofit projects to include high-performance technologies based on the long-term value to the homeowner. The pilot project focused on identifying the added costs and energy savings benefits of improvements.

  2. Nitrate reduction associated with respiration in Sinorhizobium meliloti 2011 is performed by a membrane-bound molybdoenzyme.

    2011-10-01

    The purification and biochemical characterization of the respiratory membrane-bound nitrate reductase from Sinorhizobium meliloti 2011 (Sm NR) is reported together with the optimal conditions for cell growth and enzyme production. The best biomass yield was obtained under aerobic conditions in a fed-batch system using Luria-Bertani medium with glucose as carbon source. The highest level of Sm NR production was achieved using microaerobic conditions with the medium supplemented with both nitrate and nitrite. Sm NR is a mononuclear Mo-protein belonging to the DMSO reductase family isolated as a heterodimeric enzyme containing two subunits of 118 and 45 kDa. Protein characterization by mass spectrometry showed homology with respiratory nitrate reductases. UV-Vis spectra of as-isolated and dithionite reduced Sm NR showed characteristic absorption bands of iron-sulfur and heme centers. Kinetic studies indicate that Sm NR follows a Michaelis-Menten mechanism (K (m) = 97 ± 11 ?M, V = 9.4 ± 0.5 ?M min(-1), and k (cat) = 12.1 ± 0.6 s(-1)) and is inhibited by azide, chlorate, and cyanide with mixed inhibition patterns. Physiological and kinetic studies indicate that molybdenum is essential for NR activity and that replacement of this metal for tungsten inhibits the enzyme. Although no narGHI gene cluster has been annotated in the genome of rhizobia, the biochemical characterization indicates that Sm NR is a Mo-containing NR enzyme with molecular organization similar to NarGHI.

    The Polycyclic aromatic hydrocarbons PAHs (naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene and benzo(ghi)perylene) concentrations in fine (PM 2.5) and coarse (PM 2.5-10) atmospheric particulate matter were measured at São Paulo city, Brazil. The dominant PAH compounds were indeno(1,2,3-cd)pyrene, benzo(ghi)perylene and benzo(b)fluoranthene for both the fractions. The calculated ratios of some specific PAHs were in close agreement with those attributed to direct emissions of car exhaust. The factor analysis for PM 2.5 produced four factors: Factor 1 was attributed to diesel emissions, Factor 2 was attributed to stationary combustion source, Factor 3 was attributed to vehicular emissions and Factor 4 to natural gas combustion and biomass burning. For PM 2.5-10, Factor 1 was attributed to vehicular emissions and Factor 2 was attributed to a mixture of combustion sources such as natural gas combustion, incineration emissions and oil combustion. Also, vehicular emissions were assumed to be the major source of PAHs in the São Paulo city atmosphere.

    The occurrence of polycyclic aromatic hydrocarbons (PAHs) in smoked fish as a consequence of cold smoking was studied. Raw fillets of Salmo salar from Norway or the Irish Sea were sampled in a modern smokehouse and examined for PAH content. The same fillets, labeled with an identification number, were sampled immediately after the smoking process and analyzed. Among the investigated compounds, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, and benzo[ghi]perylene were detected in both raw and smoked fillets. No significant difference (P smoked samples in the concentrations of six PAHs, but significant differences were found for fluorene, anthracene, fluoranthene, benz[a]anthracene, and benzo[ghi]perylene. Results confirm that PAHs concentrations in smoked fish are the product of both sea pollution and the smoking process. A modern smoking plant with an external smoke generator and a mild treatment as described here will not add significantly to the concentration of PAHs, except for some compounds. PMID:16715815

    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.

  6. 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.

    In the fall of 2010, a multiyear pilot energy efficiency retrofit project was undertaken by Greenbelt Homes, Inc, (GHI) a 1,566 home cooperative of circa 1930 and 1940 homes in Greenbelt, Maryland. GHI established this pilot project to serve as a basis for decision making for the rollout of a decade-long community-wide upgrade program that will incorporate energy efficiency improvements to the building envelope and mechanical equipment. With the community upgrade fully funded by the cooperative through their membership without outside subsidies, this project presents a unique opportunity to evaluate and prioritize the wide-range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project. Addressing the complex interactions between benefits, trade-offs, construction methods, project management implications, realistic upfront costs, financing, and other considerations, serves as a case study for energy retrofit projects to include high-performance technologies based on the long-term value to the homeowner. The pilot project focused on identifying the added costs and energy savings benefits of improvements. Phase 1: baseline evaluation for a representative set of 28 homes sited in seven buildings; Phase 2: installation of the building envelope improvements and continued monitoring of the energy consumption for the heating season and energy simulations supporting recommendations for HVAC and water heating upgrades to be implemented in Phase 3.

    One hundred and twenty undergraduate women students reported their height and weight and completed the Eating Disorder Questionnaire (EDQ), the Eysenck Personality Inventory (EPI), the Beck Depression Inventory (BDI), the Family Assessment Device (FAD), the Body Shape Questionnaire (BSQ), the Body Image Assessment (BIA), and measures of peer and media influence. Family functioning was shown to be a poor predictor of bulimic behavior, whereas peer influence was a significant predictor. Media influence interacted with body dysphoria to increase the likelihood of bulimic behavior. The BSQ was a better predictor of bulimic behavior than the BIA, suggesting that students' responses to a measure that asks questions about specific areas of the body may reflect their feelings of body dysphoria more accurately than a measure that relies on a generalized silhouette.

    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

    Full Text Available Antecedentes y objetivos: La obesidad infantil está aumentando alarmantemente en las últimas décadas. Para evaluar la utilidad del índice de masa corporal (IMC), el grosor del pliegue cutáneo (GPC), la circunferencia de la cintura (CC), y la impedancia bioeléctrica pie-a-pie (BIA-PP) para el cribado [...] de la obesidad en poblaciones con diversidad de razas utilizando una técnica de impedancia bioeléctrica tetrapolar (BIA-T) como el método de referencia. 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. Para los niños prepúberes, el BF-GPC-D fue el mejor método de evaluación de la grasa corporal. Conclusión: Los resultados sugieren que la BIA-PP y el IMC son los métodos de elección para el cribado de la obesidad en poblaciones mixtas y que el método de elección para el cribado de la grasa corporal debe realizarse de acuerdo con la madurez sexual de los chicos y chicas. Este estudio demuestra la necesidad de realizar estudios en poblaciones mixtas más amplias para determinar los parámetros antropológicos y examinar la capacidad predictiva de los métodos y los puntos de corte obtenidos aquí en el desarrollo de la obesidad. Abstract in english Background and aims: Childhood obesity is increasing dramatically in last decades. To evaluate the usefulness of body mass index (BMI), skinfold thickness (ST), waist circumference (WC), and foot-to-foot bioelectrical impedance (BIA-FF) for screening for obesity in mixed-race popu lation, using the [...] tetrapolar bioelectrical impedance (BIA-T) technique as reference method. 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.

    We propose a mechanism for spin polarized photocurrent generation in quantum wires. The effect is due to the combined effect of Rashba spin-orbit interaction, external magnetic field and microwave radiation. The time-independent interactions in the wire give rise to a spectrum asymmetry in k-space. The microwave radiation induces transitions between spin-splitted subbands, and, due to the peculiar energy dispersion relation, charge and spin currents are generated at zero bia...

Indeed, the BIA model has played an enormous role in showing us how bilingual visual word recognition can be achieved without recurrence to the intuitively appealing – but wrong – ideas of separate, language-specific lexicons and language-selective access. As in many other research areas, a working computational model has been much more influ...

    2015-01-01

    Nonalcoholic fatty liver disease (NAFLD) is the commonest chronic liver disease and includes simple steatosis and nonalcoholic steatohepatitis (NASH). Since NASH progresses to cirrhosis more frequently and increases liver-related and cardiovascular disease risk substantially more than simple steatosis, there is a great need to differentiate the two entities. Liver biopsy is the gold standard for the diagnosis of NAFLD but its disadvantages, including the risk of complications and sampling bia...

    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.

    Full Text Available Abstract Background Few equations have been developed in veterinary medicine compared to human medicine to predict body composition. The present study was done to evaluate the influence of weight loss on biometry (BIO, bioimpedance analysis (BIA and ultrasonography (US in cats, proposing equations to estimate fat (FM and lean (LM body mass, as compared to dual energy x-ray absorptiometry (DXA as the referenced method. For this were used 16 gonadectomized obese cats (8 males and 8 females in a weight loss program. DXA, BIO, BIA and US were performed in the obese state (T0; obese animals, after 10% of weight loss (T1 and after 20% of weight loss (T2. Stepwise regression was used to analyze the relationship between the dependent variables (FM, LM determined by DXA and the independent variables obtained by BIO, BIA and US. The better models chosen were evaluated by a simple regression analysis and means predicted vs. determined by DXA were compared to verify the accuracy of the equations. Results The independent variables determined by BIO, BIA and US that best correlated (p?r2, 19 equations were selected (12 for FM, 7 for LM; however, only 7 equations accurately predicted FM and one LM of cats. Conclusions The equations with two variables are better to use because they are effective and will be an alternative method to estimate body composition in the clinical routine. 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.

    2015-04-01

    Opium poppy (Papaver somniferum) is an important medicinal plant producing benzylisoquinoline alkaloids (BIA). MicroRNAs (miRNAs) are endogenous small RNAs (sRNAs) of approximately 21 nucleotides. They are noncoding, but regulate gene expression in eukaryotes. Although many studies have been conducted on the identification and functions of plant miRNA, scarce researches on miRNA regulation of alkaloid biosynthesis have been reported. In this study, a total of 316 conserved and 11 novel miRNAs were identified in opium poppy using second-generation sequencing and direct cloning. Tissue-specific regulation of miRNA expression was comparatively analysed by miRNA microarray assays. A total of 232 miRNAs were found to be differentially expressed among four tissues. Likewise, 1469 target transcripts were detected using in silico and experimental approaches. The Kyoto Encyclopedia of Genes and Genomes pathway analyses indicated that miRNA putatively regulates carbohydrate metabolism and genetic-information processing. Additionally, miRNA target transcripts were mostly involved in response to stress against various factors and secondary-metabolite biosynthesis processes. Target transcript identification analyses revealed that some of the miRNAs might be involved in BIA biosynthesis, such as pso-miR13, pso-miR2161 and pso-miR408. Additionally, three putatively mature miRNA sequences were predicted to be targeting BIA-biosynthesis genes. PMID:25735537

  8. U.S. grants political asylum to woman who fled female genital mutilation.

    Science.gov (United States)

    1996-06-28

    Fauziya Kasinga fled to the US from Togo in 1994 at the age of 17 years after an aunt forced her to marry a 45-year-old man with three wives. From the time of her arrival to the US in December 1994 to April 24, 1996, Kasinga was detained at two correctional facilities awaiting a decision by the US Board of Immigration Appeals (BIA) on her request for political asylum. That asylum was granted in a 11-1 decision issued on June 13 on the grounds of Kasinga's fear of being forced to undergo female genital mutilation (FGM) if sent back to Togo. This is the first time that the BIA has ruled that FGM can be grounds for asylum. 50% of women in Togo are estimated to have undergone FGM. The BIA decided that the young woman met the criteria for receiving refuge because she is a member of a particular social group, the unmutilated women of the Tchamba-Kunsuntu tribe who face but oppose FGM, which has a well-founded fear of persecution which is country wide. Moreover, Kasinga's husband has influence with the police in Togo, a rather small country. This decision not only sets precedent with regard to FGM, but also is the first gender-based asylum claim to be considered since the Immigration and Naturalization Service revised its guidelines in May 1995 to cover such persecution.

    To assess the impact of air travel on swelling of the 'at risk' arm of women treated for breast cancer. Women treated for breast cancer from Canada (n = 60) and from within Australia (n = 12) attending a dragon boat regatta in Queensland, Australia participated. Women were measured within 2 weeks prior to their flight, on arrival in Queensland and, for 40 women travelling from Canada, measured again 6 weeks following return to Canada. Changes to extracellular fluid were measured using a single-frequency bioimpedance device (BIA). Each arm was measured separately using a standardized protocol to obtain the inter-limb impedance ratio. An increase in the ratio indicates accumulated fluid. Information regarding medical management of participants' breast cancer, use of compression garment and history of exercise were also obtained. For most women (95%), air travel did not adversely affect the impedance ratio. The BIA ratio of long-haul travellers was 1.007 +/- 0.065 prior to the flight and 1.006 +/- 0.087 following the flight. The ratio of short-haul travellers was 0.994 +/- 0.033 and following the flight was 1.001 +/- 0.038. Air travel did not cause significant change in BIA ratio in the 'at-risk' arm for the majority of breast cancer survivors who participated in dragon boat racing. Further research is required to determine whether these findings are generalizable to the population of women who have been treated for breast cancer. PMID:20180016

    Background and Aims Bioelectrical impedance analysis (BIA) is a widely used technique to assess body composition and nutritional status. While bioelectrical values are affected by diverse variables, there has been little research on validation of BIA in acute illness, especially to understand prognostic significance. Here we report the use of BIA in acute febrile states induced by influenza. Methods Bioimpedance studies were conducted during an H1N1 influenza A outbreak in Venezuelan Amerindian villages from the Amazonas. Measurements were performed on 52 subjects between 1 and 40 years of age, and 7 children were re-examined after starting Oseltamivir treatment. Bioelectrical Impedance Vector Analysis (BIVA) and permutation tests were applied. Results For the entire sample, febrile individuals showed a tendency toward greater reactance (p=0.058) and phase angle (p=0.037) than afebrile individuals, while resistance and impedance were similar in the two groups. Individuals with repeated measurements showed significant differences in bioimpedance values associated with fever, including increased reactance (p<0.001) and phase angle (p=0.007), and decreased resistance (p=0.007) and impedance (p<0.001). Conclusions There are bioelectrical variations induced by influenza that can be related to dehydration, with lower extracellular to intracellular water ratio in febrile individuals, or a direct thermal effect. Caution is recommended when interpreting bioimpedance results in febrile states. PMID:25915945

    Two manually guided brief interventions were evaluated with a randomized, controlled trial. Adolescents (aged 13-17 years) suspected of abusing alcohol and other drugs and their parent were randomly assigned to receive either a 2-session adolescent only (BI-A), 2-session adolescent and additional parent session (BI-AP), or assessment only control condition (CON). Adolescents were identified in a school setting, and the intervention was delivered by trained counselors. Outcome analyses (N = 284; 90% of those enrolled) of relative change (from intake to 12 months) and absolute status (at 12 months) revealed a general pattern of reductions in drug use behaviors, particularly with the cannabis outcome measures, in both active conditions (BI-A and BI-AP). Students in the control condition showed worse outcome compared with the BI-A and BI-AP groups. Among the 4 mediating variables measured at 6 months, use of additional services, motivation to change, and parenting practices had significant influences on 12-month outcome; problem-solving skills approached significance as a mediator. The potential value of a brief intervention for drug abusing adolescents is discussed. PMID:24955669

    Introduction: Bioelectrical impedance analysis (BIA) is a useful tool to asses human body composition and nutrition status; multi-frequency BIA has a higher accuracy than single-frequency BIA. In our study a difference of impedance values (Z) at 5, 100 and 200 kHz and Z200/Z5 index between professional athletes and control group were determined. Methods: In this research 105 people were tested, divided into control group (72 people: 35 males and 37 females) and professional athletes (33 people: 16 males and 17 females). Impedance was measured at three frequency values - 5, 100 and 200 kHz; with received values the Z200/Z5 index was calculated. Results: In most compared subgroups impedance values showed significantly lower values in athletes than in control group (5 kHz - males: p=0.136, females: p=0.001, 100 kHz - males: p=0.039, females: pnutrition status and general health condition of athletes than in control group.

    2012-01-01

    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.

    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.

    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.)

  3. Quantification of polynuclear aromatic hydrocarbons in industrial waste water using temperature programmed capillary gas chromatography

    International Nuclear Information System (INIS)

    Polynuclear aromatic hydrocarbons PAHs have been quantified in waste water of industrialized area of Kalashahkaku (Lahore, Pakistan). The PAHs were isolated from waste water by solvent extraction using dichloromethane (DCM) as extractant. After sample clean-up step and volume reduction under vacuum, the separation of PAHs concentrate into individual constituents is achieved by gas chromatography using flame ionization detector (FID). Mostly high molecular weight PAHs namely pyrene, benzo (a) anthracene, chrysene, benzo (K) fluoranthene, benzo (a) pyrene, benzo (ghi) perylene, indeno (1,2,3 cd) pyrene and coronene have been detected ranging from 41.1 g/l for benzo (a) anthracene to 85.0 g/l for benzo (K) fluoranthene.

    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.

    Samples of seaweed which are used for human consumption were collected along the Galician coast (NW Spain), in order to determine the level of contamination from polycyclic aromatic hydrocarbons, by supercritical fluid extraction and liquid chromatographic analysis. No detection was made of benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene, benzo[ghi]perylene and dibenzo[ah]anthracene. PAHs were found and quantified in only two samples. The PAHs found were the following: anthracene, chrysene, fluoranthene, fluorene and pyrene. The levels found were below maximum limits established by the Spanish Food Safety authority (<200 mg/kg dry weight). Here we show that no relevant effects were detected in terms of PAHs contamination in seaweed. PMID:18654728

Here, the first compound-specific radiocarbon analysis (CSRA of atmospheric polycyclic aromatic hydrocarbons (PAHs was demonstrated for a set of samples collected in Lycksele, Sweden a small town with frequent episodes of severe atmospheric pollution in the winter. Renewed interest in using residential wood combustion (RWC means that this type of seasonal pollution is of increasing concern in many areas. Five individual/paired PAH isolates from three pooled fortnight-long filter collections were analyzed by CSRA: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene plus benzo[ghi]perylene; phenanthrene was the only compound also analyzed in the gas phase. The measured ?14C for PAHs spanned from ?138.3‰ to 58.0‰. A simple isotopic mass balance model was applied to estimate the fraction biomass (fbiomass contribution, which was constrained to 71–87% for the individual PAHs. Indeno[cd]pyrene plus benzo[ghi]perylene had an fbiomass of 71%, while fluoranthene and phenanthrene (gas phase had the highest biomass contribution at 87%. The total organic carbon (TOC, defined as carbon remaining after removal of inorganic carbon fbiomass was estimated to be 77%, which falls within the range for PAHs. This CSRA data of atmospheric PAHs established that RWC is the dominating source of atmospheric PAHs to this region of the boreal zone with some variations among RWC contributions to specific PAHs.

    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.

    Providing publicly accessible high-quality and long-term satellite based solar resource datasets for the US reduces barriers to solar grid penetration. There are two widely used approaches to derive solar resource from satellites (a) an empirical approach that relates ground based observations with satellite measurements and (b) a physics based approach that considers the radiation received at the satellite and create retrievals to estimate clouds and surface radiation. While empirical methods have been traditionally used for computing surface radiation 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 the Satellite Algorithm for Surface Radiation Budget (SASRAB) model to calculate surface radiation. NREL, University of Wisconsin and NOAA have recently collaborated to adapt GSIP to create a high temporal and spatial resolution dataset. The product initially generates the cloud properties through applying the AVHRR Pathfinder Atmospheres-Extended (PATMOS-x) algorithms on GOES data while the global horizontal radiation (GHI) and diffuse horizontal radiation (DHI) are calculated using SASRAB. Comparison with ground sites resulted in the finding that the satellite based surface radiation suffered from a significant low-bias. The most significant bias occurred in clear-sky situation. To remove this clear-sky bias we tested three new radiative transfer algorithms that required aerosol optical depth and precipitable water vapor as inputs. These experiments showed significant improvement in the clear sky radiation (Figure 1). We will present an outline of the development of this new version of the NSRDB, a validation of the product and future plans for enhancement and improvement.

    Full Text Available En el presente trabajo se expone el monitoreo de termokarts glaciarios y su relación e interacción con los eventos surges ocurridos en el glaciar cubierto Horcones Inferior (GHI. Este glaciar se encuentra ubicado a los 32º 41'S y 69º 57'W, al pie de la pared sur del C° Aconcagua, Parque Provincial Aconcagua, en la Provincia de Mendoza, Argentina. El estudio fue llevado a cabo a través de la implementación de métodos indirectos de detección utilizando imágenes de los sensores Landsat y Aster durante el período 1997-2006. En el Glaciar Horcones Inferior "GHI", la superficie ocupada por los termokarst alcanza valores que varían entre el 4.3% y el 0% de la superficie total del glaciar, al finalizar un evento de surge. Las velocidades registradas en la superficie del glaciar cubierto arrojaron valores promedios entre 0.4 y 12 m/día. La metodología aplicada, con imágenes satelitales históricas, representa una herramienta fundamental para separar períodos de flujo glaciario catastróficos y no catastróficos.This work analyses the temporal evolution of thermokarst and their relationship to the surges in a reconstituted debris covered glacier. The glacier Horcones Inferior is located at Lat 32º 41' S and Long 69º 57' W in the Provincial Park Aconcagua, Mendoza, Argentina, on the foot of the Aconcagua massif. The study and monitoring of the thermokarst was carried out applying indirect methods using Landsat and Aster images from 1997-2006. Detected percentages of thermokarst, in relation to the total glacial area, showed that they varied between 4.3% to 0% at the end of the surge event. The registered speeds of the glacier -on the glacial surface- reached averages of between 0.4 and 12 m/d. This methodology, with historical images from archives, represents a fundamental tool to separate catastrophic and non-catastrophic glacial flow periods.

    Full Text Available 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.

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.

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.

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.

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.

    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.

Até o momento, não havia recomendações específicas para o desenvolvimento de AIO no Brasil. O presente trabalho apresenta uma revisão dos métodos usados nas AIO de tecnologias da saúde e propõe recomendações para seu uso nos âmbitos do SUS e do sistema de saúde suplementar. As recomendações principais são: analisar pela perspectiva do gestor; empregar horizonte temporal de um a cinco anos; comparar cenários de referência e alternativos; considerar taxa de incorporação da tecnologia; delimitar a população de interesse pela abordagem epidemiológica ou por demanda aferida; considerar restrições para acesso ou fatores indutores de demanda; considerar custos diretos incorridos e evitados; não ajustar para inflação ou descontos; integrar as informações em planilha eletrônica; calcular o impacto orçamentário diferencial entre cenários; sintetizar as informações em um relatório de impacto orçamentário.Budget impact analysis (BIA provides operational financial forecasts to implement new technologies in healthcare systems. There were no previous specific recommendations to conduct such analyses in Brazil. This paper reviews BIA methods for health technologies and proposes BIA guidelines for the public and private Brazilian healthcare system. The following recommendations were made: adopt the budget administrator's perspective; use a timeframe of 1 to 5 years; compare reference and alternative scenarios; consider the technology's rate of incorporation; estimate the target population by either an epidemiological approach or measured demand; consider restrictions on technologies' indication or factors that increase the demand for them; consider direct and averted costs; do not adjust for inflation or discounts; preferably, integrate information on a spreadsheet; calculate the incremental budget impact between scenarios; and summarize information in a budget impact report.

We aimed to fi nd out if body position has an effect on the BIA results. MATERIAL and METHODS: Personal characteristics including age, gender, height, weight and blood pressure were recorded. Hydration and nutritional status measured by body composition monitor in supine and standing positions consequently for each individual. RESULTS: Two hundred and one populations from various region in Turkey, 61% (n: 123 male, mean age was 46.3±12 years (18-76 of age, participated in this crossectional study. From supine to standing positions overhydration and extracellular water (ECW were increased from 0.04±1.08 and 17.69±2.92 to 0.46±1.05 L and 17.84±2.90 L while intracellular water (ICW decreased from 22.55±4.35 to 22.04±4.28 L signifi cantly. Systolic and diastolic blood pressures were 131.3±18.1 and 75.1±12 decreased to 127.0±16.0 and 72.2±9.0 mmHg in supine to standing positions (p> 0.05. CONCLUSION: Supine and standing positions could affect the volume parameters of BIA due to shift of ECW and ICW by gravity but nutritional parameters also changes signifi cantly. Protocols should be re evaluated in order to get more accurate results in bioimpedance measurements.

    The physiological well-being or condition of fish is most commonly estimated from aspects of individual morphology. However, these metrics may be only weakly correlated with nutritional reserves stored as lipid, the primary form of accumulated energy in fish. We constructed and evaluated bioelectrical impedance analysis (BIA) models as an alternative method of assessing condition in amphidromous Dolly Varden Salvelinus malma collected from nearshore estuarine and lotic habitats of the Alaskan Arctic. Data on electrical resistance and reactance were collected from the lateral and ventral surfaces of 192 fish, and whole-body percent lipid and moisture content were determined using standard laboratory methods. Significant inverse relationships between temperature and resistance and reactance prompted the standardization of these data to a constant temperature using corrective equations developed herein. No significant differences in resistance or reactance were detected among spawning and nonspawning females after accounting for covariates, suggesting that electrical pathways do not intersect the gonads. Best-fit BIA models incorporating electrical variables calculated from the lateral and ventral surfaces produced the strongest associations between observed and model-predicted estimates of proximate content. These models explained between 6% and 20% more of the variability in laboratory-derived estimates of proximate content than models developed from single-surface BIA data and 32% more than models containing only length and weight data. While additional research is required to address the potential effects of methodological variation, bioelectrical impedance analysis shows promise as a way to provide high-quality, minimally invasive estimates of Dolly Varden lipid or moisture content in the field with only small increases in handling time.

    Full Text Available Abstract Background A frequent manifestation of advanced lung cancer is malnutrition, timely identification and treatment of which can lead to improved patient outcomes. Bioelectrical impedance analysis (BIA is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated the prognostic role of BIA-derived phase angle in advanced non-small cell lung cancer (NSCLC. Methods A case series of 165 stages IIIB and IV NSCLC patients treated at our center. The Kaplan Meier method was used to calculate survival. Cox proportional hazard models were constructed to evaluate the prognostic effect of phase angle, independent of stage at diagnosis and prior treatment history. Results 93 were males and 72 females. 61 had stage IIIB disease at diagnosis while 104 had stage IV. The median phase angle was 5.3 degrees (range = 2.9 – 8. Patients with phase angle 5.3 had 12.4 months (95% CI: 10.5 to 18.7; n = 84; (p = 0.02. After adjusting for age, stage at diagnosis and prior treatment history we found that every one degree increase in phase angle was associated with a relative risk of 0.79 (95% CI: 0.64 to 0.97, P = 0.02. Conclusion We found BIA-derived phase angle to be an independent prognostic indicator in patients with stage IIIB and IV NSCLC. Nutritional interventions targeted at improving phase angle could potentially lead to an improved survival in patients with advanced NSCLC.

    Background: Deranged body fat and muscle mass are aftermaths of uncontrolled diabetes. Anthropometric methods like body mass index (BMI) do not give qualitative inferences like total body fat (TBF), visceral fat (VF) or subcutaneous fat (SF) that can be given by bio-electrical impedance analysis (BIA). We studied body composition of type 2 diabetics in comparison to controls matched by age-sex, weight and BMI separately. Methods: Seventy-eight under-treatment type 2 diabetics of either sex with known glycemic and lipidemic control and equal number of controls with three patterns of matching were taken from our city. We derived parameters of body composition in both groups by Omron Karada Scan (Model HBF-510, China), using the principle of tetra poplar BIA and compared them for statistical significance. Results: We found significantly more SF (30.47% ± 7.73%), VF (11.94% ± 4.97%) and TBF (33.96% ± 6.07%) and significantly lesser skeletal muscle mass (23.39% ± 4.49%) in type 2 diabetics as compared to controls, persisting even after matching with weight or BMI. On assessing qualitatively, the risk of high VF, high TBF, low skeletal muscle mass was significantly high in type 2 diabetics, which were 10.41, 3.01, 9.21 respectively for comparable BMI and 6.78, 3.51, 11.93 respectively for comparable weight. Conclusions: BIA reveals that type 2 diabetics have more ectopic fat on the expense of skeletal muscle that persists even after matching by weight or BMI, both quantitatively and qualitatively. Measurement of body composition can be included as a primary care strategy to motivate lifestyle modifications while managing metabolic derangements of type 2 diabetes. PMID:26900436

    Pyronaridine tetraphosphate (1) is a well-known antimalarial drug. However, it required a carefully optimized production process for the manufacture of pyronaridine tetraphosphate. Each step of its manufacturing process was reinvestigated. For the cyclization of 4-chloro-2-(6-methoxy-pyridin-3-yl-amino)-benzoic acid 6 to 7,10-dichloro-2-methoxybenzo[b]-1,5-naphthyridine 5, an improved process was developed to eliminated critical process impurity (BIA). By the redesign of the formation of triphosphate salt, the purity as API grade was increased. Thus, a robust manufacturing process with an acceptable process performance has been developed to produce high quality pyronaridine tetraphosphate.

    There are a number of reports regarding natural infection of Dermacentor reticulatus ticks with TBE virus; however, the transmission mode of TBE virus in this tick population has not been investigated. This study was conducted in Bia?owie?a Primeval Forest, east Poland. Forty fully engorged nymphs of D. reticulatus were sampled from root voles (Microtus oeconomus). Ticks were kept until molting. All ticks were screened for the presence of TBE virus by nested RT-PCR. Three adult ticks were positive for infection with TBE virus. The present study for the first time demonstrates the possibility of transstadial mode of TBEV transmission in D. reticulatus ticks. PMID:26751892

  7. Charge and spin transport in spin valves with anisotropic spin relaxation

    2006-01-01

    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.

  19. Compound-specific radiocarbon analysis of atmospheric PAH from a wood smoke-impacted city in Northern Sweden

    International Nuclear Information System (INIS)

    Full text: Atmospheric polycyclic aromatic hydrocarbons (PAHs) are ubiquitous due to their emission from a variety of combustion sources including motor vehicle exhaust and other fossil fuel combustion and biomass burning. Their potential to detrimentally impact human and ecological health makes it vital to apportion these compounds to emission sources. PAHs also have a wide range in volatility and can be present in both the gas and particulate phase in the atmosphere. However, PAHs present in high concentrations in the atmosphere are not source-specific and can be difficult to trace back to their original emission sources. Natural abundance radiocarbon analysis offers a trusted method for determining the fraction of modern versus fossil carbon and recent advances in micro-scale techniques have opened the door for compound class-specific radiocarbon analysis (CCSRA) of organic compounds at the low levels present in environmental samples. Atmospheric levels of PAHs provide a particular challenge due to difficulties in obtaining a sample with sufficient mass for radiocarbon analysis. Initial studies in Europe and Japan have shown a wide range of biomass burning contribution from 10 % of pooled PAHs for two background sites in south Europe to up to 45 % in Tokyo and 50 % at a background site in Sweden. Compound-specific radiocarbon analysis (CSRA) of atmospheric PAHs would further enhance the understanding of emission source impacts on ambient concentrations and has not been previously reported. In this study, CSRA was applied to a set of atmospheric samples collected in Lycksele, a city in Northern Sweden which has frequent episodes of severe atmospheric pollution in the winter. Previous studies carried out in the city have shown that wood combustion for residential heating has a large impact on atmospheric aerosol followed by motor vehicle emissions. This combination provided an ideal location for CSRA to apportion atmospheric PAHs between fossil fuel combustion and wood smoke. In order to maximize sample collection mass, a high volume total suspended particulate matter (TSP) sampler loaded with quartz fiber filters for PM collection and PUFs (polyurethane foam) for volatile species was used in this study. Five different particulate PAH samples were analyzed by CSRA including: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene+benzo[ghi]perylene whereas phenanthrene was the only compound also analyzed in the gas phase. The percentage wood smoke contribution ranged from 70 % for indeno[cd]pyrene+benzo[ghi]perylene to 87 % for the PUF phenanthrene and particulate pyrene. There was a distinct molecular-weight trend (r2 = 0.68) to the fraction wood smoke contribution with higher contribution for the lower molecular-weight PAHs. (author)

  1. What contributes to the combined effect of a complex mixture?

    Altenburger, Rolf; Walter, Helge; Grote, Matthias

    2004-12-01

    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 improves the description of the observed combined effect. Allocation of effect contributions to specific components using toxic units or effect contributions lead to different judgments. The observed combined effect of a 3-compound mixture of prometryn, N-phenyl-2-naphthylamine, and benzo[ghi]fluoranthene is indistinguishable from the effects of the original 10-compound mixture, demonstrating the need in site-specific assessment of complex contamination to account for the mode of action of contaminants. Implications forthe confirmation step in effect-directed analysis of substances causing effects in complex contaminated samples are discussed. PMID:15597892

Immunostaining was performed by biotin-streptavidin-peroxidase system. Positive ER? immunostaining was observed in nuclei of carcinoma cells, myoepithelial cells and chondrocites. It was determined the percentage of nuclei immunolabeled according to histological type (simple carcinoma: 51%, complex carcinoma: 61%, mixed carcinoma: 63%), histologic grade of malignancy (GHI: 60% and GHII: 61%), the clinical stage (ECI: 68%, ECII: 56%, ECIII: 59%, ECIV: 58% and ECV 58%) and in accordance with survival at 18 months (live: 61% and dead: 60%). These results show higher percentages in groups of better prognosis (although no significant differences were established) in coincidence with the opinions expressed by others, except in reference to the histological grade of malignancy. These conflicting data suggest that further analysis to assess ER? prognostic potential in canine mammary tumors is needed.

    Publicly accessible, high-quality, long-term, satellite-based solar resource data is foundational and critical to solar technologies to quantify system output predictions and deploy solar energy technologies in grid-tied systems. Solar radiation models have been in development for more than three decades. For many years, the National Renewable Energy Laboratory (NREL) developed and/or updated such models through the National Solar Radiation Data Base (NSRDB). There are two widely used approaches to derive solar resource data from models: (a) an empirical approach that relates ground-based observations to satellite measurements and (b) a physics-based approach that considers the radiation received at the satellite and creates retrievals to estimate clouds and surface radiation. Although empirical methods have been traditionally used for computing surface radiation, the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is an operational physical model from the National Oceanic and Atmospheric Administration (NOAA) that computes global horizontal irradiance (GHI) using the visible and infrared channel measurements from the Geostationary Operational Environmental Satellites (GOES) system. GSIP uses a two-stage scheme that first retrieves cloud properties and then uses those properties in the Satellite Algorithm for Surface Radiation Budget (SASRAB) model to calculate surface radiation. NREL, the University of Wisconsin, and NOAA have recently collaborated to adapt GSIP to create a high temporal and spatial resolution data set. The product initially generates the cloud properties using the AVHRR Pathfinder Atmospheres-Extended (PATMOS-x) algorithms [3], whereas the GHI is calculated using SASRAB. Then NREL implements accurate and high-resolution input parameters such as aerosol optical depth (AOD) and precipitable water vapor (PWV) to compute direct normal irradiance (DNI) using the DISC model. The AOD and PWV, temperature, and pressure data are also combined with the MMAC model to simulate solar radiation under clear-sky conditions. The current NSRDB update is based on a 4-km x 4-km resolution at a 30-minute time interval, which has a higher temporal and spatial resolution. This paper demonstrates the evaluation of the data set using ground-measured data and detailed evaluation statistics. The result of the comparison shows a good correlation to the NSRDB data set. Further, an outline of the new version of the NSRDB and future plans for enhancement and improvement are provided.

  4. Consequences of flagellin export through the type III secretion system of Pseudomonas syringae reveal a major difference in the innate immune systems of mammals and the model plant Nicotiana benthamiana.

    Bacterial flagellin is perceived as a microbe (or pathogen)-associated molecular pattern (MAMP or PAMP) by the extracellular pattern recognition receptors, FLS2 and TLR5, of plants and mammals respectively. Flagellin accidently translocated into mammalian cells by pathogen type III secretion systems (T3SSs) is recognized by nucleotide-binding leucine-rich repeat receptor NLRC4 as a pattern of pathogenesis and induces a death-associated immune response. The non-pathogen Pseudomonas fluorescens Pf0-1, expressing a Pseudomonas syringae T3SS, and the plant pathogen P. syringae pv. tomato DC3000 were used to seek evidence of an analogous cytoplasmic recognition system for flagellin in the model plant Nicotiana benthamiana. Flagellin (FliC) was secreted in culture and translocated into plant cells by the T3SS expressed in Pf0-1 and DC3000 and in their ?flgGHI flagellar pathway mutants. ?fliC and ?flgGHI mutants of Pf0-1 and DC3000 were strongly reduced in elicitation of reactive oxygen species production and in immunity induction as indicated by the ability of challenge bacteria inoculated 6 h later to translocate a type III effector-reporter and to elicit effector-triggered cell death. Agrobacterium-mediated transient expression in N. benthamiana of FliC with or without a eukaryotic export signal peptide, coupled with virus-induced gene silencing of FLS2, revealed no immune response that was not FLS2 dependent. Transiently expressed FliC from DC3000 and Pectobacterium carotovorum did notinduce cell death in N. benthamiana, tobacco or tomato leaves. Flagellin is the major Pseudomonas?MAMP perceived by N. benthamiana, and although flagellin secretion through the plant cell wall by the T3SS may partially contribute to FLS2-dependent immunity, flagellin in the cytosol does not elicit immune-associated cell death. We postulate that a death response to translocated MAMPs would produce vulnerability to the many necrotrophic pathogens of plants, such as P.?carotovorum, which differ from P. syringae and other (hemi)biotrophic pathogens in benefitting from death-associated immune responses.

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

    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.

    Acute lung injury (ALI) is a serious clinical syndrome with a high rate of mortality. In this study, the effects of apocynin, a NADPH-oxidase (NOX) inhibitor on lipopolysaccharide (LPS)-induced ALI in rats were investigated. Male Sprague-Dawley rats were treated with apocynin (10mg/kg) intraperitoneally (i.p.) 1h before LPS injection (10mg/kg, i.p.). The results revealed that apocynin attenuated LPS-induced ALI as it decreased total protein content, lactate dehydrogenase (LDH) activity and the accumulation of the inflammatory cells in the bronchoalveolar lavage fluid (BALF), In addition, apocynin significantly increased superoxide dismutase (SOD) and reduced glutathione (GSH) activities with significant decrease in the lung malondialdehyde (MDA) content as compared to LPS group in lung tissue and decreased pulmonary artery contraction induced by LPS. It also upregulated mRNA expression of inhibitory protein kappaB-alpha (NF?Bia) and downregulated mRNA expression of Toll-Like receptor 4 (TLR4) and decreased inflammation observed in lung tissues. Collectively, these results demonstrate the protective effects of apocynin against the LPS-induced ALI in rats through its antioxidant and antiinflammatory effect that may be attributed to the decrease in mRNA expression of TLR4 and increasing that of NF?Bia.

    The objective of the present study was to estimate the advantages of cochlear Baha BIA 400 abutments in the intraoperative and early postoperative periods. A total of 10 implantations of the systems with the use of hydroxyapatite bone cement were performed in 9 patients of different age. Stability of the implants and intensity of skin reactions were evaluated. The data obtained indicate that the use of cochlear Baha BIA 400 abutments significantly simplifies and shortens the surgical stage of rehabilitation producing a good cosmetic result. The use of the Osstell instrument made it possible to estimate stability of the implants intraoperatively and evaluate the effectiveness of osteointegration during the follow-up period. Analysis of the results of the study provided a basis on which to improve the quality and shorten duration of the rehabilitative treatment of the patients presenting with congenital external and middle ear malformations. Moreover, the data obtained can be used to develop practical recommendations for the further work in this area. PMID:24781169

  10. Screening for sarcopenia in obesity

    International Nuclear Information System (INIS)

    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.

    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.

    Full Text Available Prolonged total food deprivation in non-obese adults is rare, and few studies have documented body composition changes in this setting. In a group of eight hunger strikers who refused alimentation for 43 days, water and energy compartments were estimated, aiming to assess the impact of progressive starvation. 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 efficient energy and muscle conservation. Conclusions: 1 All compartments diminished during fasting, but body fat was by far the most affected; 2 Total water was low and total body resistance comparatively elevated, but these findings rapidly reversed upon rehydration; 3 Exaggerated fat percentage estimates from BIA tests and simultaneous increase in lean body mass estimates suggested that this method was inappropriate for assessing energy compartments in the studied population; 4 Patients were not morphologically malnourished after 43 days of fasting; however, the prognostic impact of other impairments was not considered in this analysis.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, visando 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.

    Inflammatory bowel diseases (IBD) are characterised by periods of disease activity and period with disease in remission. In Denmark all patients are seen in hospital settings. The aim of this study was to introduce a nurse-led phone service for stable patients replacing annual visits. The study originated from an outpatient cohort of 1,600 patients with IBD. A research protocol was determined before the intervention was launched, which included surveys among the patients before the intervention, after the intervention, collection of longitudinal data in a three year period, and a clinical audit. Budget impact analysis (BIA) and cost-effectiveness analysis (CEA) were done. Furthermore, the staff evaluated the process. Almost 30% (n = 474) of the total cohort was enrolled in the service. Eighty-seven per cent of the patients welcomed the phone service beforehand. After implementation, 94% of the patients included were pleased with the service. The programme has shortened the waiting time for most other services, but no improvement in the workload was observed. The BIA showed limited savings. The CEA showed an annual saving of 100€ per patient when using the annual phone service over routine visits. In conclusion, changing the method of contact from routine annual visits to annual phone calls from a nurse was feasible and well accepted for stable patients with IBD. The benefits of the service were most marked for the patients.

    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.

  17. 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)

  18. Language control in bilingual language comprehension: evidence from the maze task.

    Most empirical evidence on switch costs is based on bilingual production and interpreted as a result of inhibitory control. It is unclear whether such a top-down control process exists in language switching during comprehension. This study investigates whether a non-lexical switch cost is involved in reading code-switched sentences and its relation to language dominance with cross-script bilingual readers. A maze task is adopted in order to separate top-down inhibitory effects, from lexical effects driven by input. The key findings are: (1) switch costs were observed in both L1-L2 and L2-L1 directions; (2) these effects were driven by two mechanisms: lexical activation and inhibitory control; (3) language dominance modulated the lexical effects, but did not affect the inhibitory effects. These results suggest that a language control mechanism is involved in bilingual reading, even though the control process is not driven by selection as in production. At the theoretical level, these results lend support for the Inhibitory Control model during language switching in comprehension; while the BIA/BIA+ model needs to incorporate a top-down control mechanism to be able to explain the current findings.

    Purpose We determined whether human immunodeficiency virus (HIV) infection affects body cell mass and fat mass wasting among adults with pulmonary tuberculosis (PTB). Methods We screened 967 Ugandan adults for PTB and HIV infection in a cross-sectional study. We compared anthropometric and bioelectric impedance analysis (BIA) body composition parameters among HIV-seropositive and HIV-seronegative men and women with or without PTB using a non-parametric test. Results We found that poor nutritional status associated with TB differed among men and women. Anthropometric and BIA body composition did not differ between HIV-seropositive and HIV-seronegative patients regardless of gender. Average weight group difference in men comprised of body cell mass and fat mass in equal proportions of 43%. In women, average weight group difference comprised predominantly of fat mass of 73% and body cell mass of 13%. Compared to individuals without TB, patients with TB had lower body mass index, weight, body cell mass, and fat mass regardless of gender and HIV status. Conclusions Gender but not HIV status was associated with body composition changes in TB. Tuberculosis appears to be the dominant factor driving the wasting process among co-infected patients.
