Ghi?? Ionescu, Communism in Romania. A book to be reread  

Directory of Open Access Journals (Sweden)

Full Text Available The present paper advocates a contemporany reading of the volum of Ghi?? Ionescu, „Comunismul în România“. Being a relevant picture of the communist regime, the volume guides the discussion towards the theory of „communist legacy“,a general formula designating the genetic explanation of post-communism. This is, therefore, the theoretical perspective under which we propose to (rereading this book.

Rheology and BIA  

International Nuclear Information System (INIS)

Is it possible to link erythrosedimentation to a global monofrequency of 50KHz bio impedance analysis parameters? Two populations, Control (N=20, average age of 38 ± 18 years, 55% female predominance) versus neopathology undergoing chemotherapy treatment (N=10, average age of 51 ± 10 years, 70% female predominance) were exposed to two simple tests: Blood composition and erythrosedimentation and global Bio Impedance mono frequency (50 KHz) assessment analysis. The Results of simple statistical tests (average, anova) show that the two populations were significantly different (1%), using both biological bood tests or BIA. Only the neopathological group showed a significant correlation between the erythrosedimentation the bio impedance parameters such as Phase angle or Xc (ratio ? 0.93 and ? 0.93)

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

Directory of Open Access Journals (Sweden)

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.

Resistivity and phase in localized BIA  

Science.gov (United States)

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.

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.

On the Balmer discontinuity of BIa supergiants  

Science.gov (United States)

Observed Balmer discontinuities of BIa supergiants, obtained in the Barbier-Chalonge-Divan system using 13-color photometry, are compared with those predicted using classical models of stellar atmospheres. The differences noted between observations and theory for beta = 1 are shown to be a function of the effective temperature. Radii of the supergiants are usually higher when the spectral type is later, suggesting that models of extended atmospheres may explain both the Balmer discontinuities of the supergiants and their far-UV flux distributions.

Die Bedeutung der bioelektrischen Impedanzanalyse (BIA im geriatrischen Bereich  

Directory of Open Access Journals (Sweden)

Full Text Available Die bioelektrische Impedanzanalyse (BIA wird seit ca. 20 Jahren als schnelle und nichtinvasive Methode zur Bestimmung der Körperzusammensetzung eingesetzt. Nach Anlegen von je zwei Meßelektroden an Hand und Fuß des Probanden werden im hochfrequenten Wechselstromfeld (meist 50 kHz bei konstanter Stromstärke die Widerstände Resistanz (Rz, Ohmscher Widerstand und Reaktanz (Xc, kapazitiver Widerstand gemessen. Die physikalischen Grundlagen zur Auswertung der Meßergebnisse sind seit langem bekannt und folgen dem Ohmschen Gesetz. Der menschliche Körper wird modellhaft als System elektrischer Leiter betrachtet, wobei parallel und seriell verknüpfte Gewebe die Leiterbahnen darstellen. Für die Auswertung ist entscheidend, daß verschiedene Gewebe- und Zellarten den Strom unterschiedlich gut leiten. Das Skelett und die Fettmasse leiten den Strom so schlecht, daß sie bei der Widerstandsmessung mittels BIA nicht erfaßt werden. Das Muskelgewebe und die Extrazellulärräume leiten den Strom wesentlich besser und machen den Hauptanteil der Widerstandsmessung mit BIA aus.

Characterization of a new efflux pump, MexGHI-OpmD, from Pseudomonas aeruginosa that confers resistance to vanadium.  

Science.gov (United States)

Vanadium has an antibacterial activity against Pseudomonas aeruginosa, especially under conditions of iron limitation. Some degree of resistance to V is inducible by prior exposure to the metal. One mutant (VS1) with a higher sensitivity to V was obtained by transposon mutagenesis of P. aeruginosa PA 59.20, a clinical isolate. This mutant had an insertion in a non-coding region, upstream of a cluster of four genes. Three of them show similarities to genes corresponding to known P. aeruginosa antibiotic efflux systems, including an efflux protein, a membrane fusion protein and an outer-membrane porin. This cluster was named mexGHI-opmD. By allelic exchange, three mutants, ncr (for non-coding region), mexI and opmD were constructed in P. aeruginosa PAO1. Next to V sensitivity, the ncr, mexI and opmD mutants also showed reduced production of elastase, rhamnolipids, pyocyanine, pyoverdine and had reduced swarming motility, phenotypes that are known to be regulated by quorum sensing. All wild-type phenotypes, including growth in the presence of V, were restored by complementation with the complete cluster. The production of N-acyl-homoserine lactones (AHLs) was detected using the Chromobacter violaceum bioassay. Total extracts from the three mutants failed to induce the production of violacein by C. violaceum, although AHLs were detected by TLC and C. violaceum overlay. Violacein production was restored by complementation with mexGHI-opmD. The opmD mutant grew very slowly in LB or CAA medium, indicating that OpmD has an important physiological function for the cell. In conclusion, it is believed that the MexGHI-OpmD pump is probably involved in AHL homeostasis in P. aeruginosa. PMID:12177331

Product ion studies of diastereomeric benzo[ghi]fluoranthene-2'-deoxynucleoside adducts by electrospray ionization and quadrupole ion trap mass spectrometry  

International Nuclear Information System (INIS)

The product ion formation characteristics of the protonated molecule ions generated from 10 different deoxynucleoside adducts of benzo[ghi]fluoranthene (B[ghi]F) have been studied using electrospray ionization (ESI) and quadrupole ion trap mass spectrometry to gain a better understanding of the fragmentation mechanisms that govern structure-specific fragmentation. The reaction of the syn- and anti-diastereomers of trans-3,4-dihydroxy-5,5a-tetrahydrobenzo[ghi]fluoranthene with DNA produce four deoxyguanosine, four deoxyadenosine, and two deoxycytidine adducts whose structures differ based on the cis/trans arrangement of the hydroxyl groups and nucleic acids bound to B[ghi]F. Those adducts that have structures where the nucleic acid and 3'-hydroxyl group of B[ghi]F are cis with respect to each other undergo extensive water loss whereas those isomers where the nucleic acid and 3'-hydroxyl group are trans do not. These results are consistent with a mechanism of water loss initiated by a hydrogen-bonding interaction between the charge-bearing proton on a heterocyclic nitrogen atom on the nucleic acid and the 3'-hydroxyl oxygen on the PAH. The dG and dC adducts are observed to undergo more extensive water loss than the dA adducts. Molecular modeling indicates that the larger relative abundances of the product ions formed by water loss for the dG and dC relative to dA are due to stronger hydrogen-bonding interactions prior to fragmentation and the greater stability of the carbocations formed at the C3' carbon after fragmentation

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

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

Bioelectrical impedance analysis (BIA): a proposal for standardization of the classical method in adults  

International Nuclear Information System (INIS)

The accuracy of BIA measurements is limited by different sources of error such as physical model, cross sectional area, ethnicity, body hydration, age and level of body fat among other variables. Equation for each population is required as they can produce overestimation when manufacturer's equations are used. The classical measurements hand to foot has shown better correlation against hydrodensitometry than foot to foot or hand to hand. However there is a lack for an accepted standard of BIA procedures. This is compounded when there is not a good report of the BIA study's methodology; hence the comparability between the results is poor and reduces the reliability of the method. Perhaps, standardization of methods would be the first step for BIA studies to move forward and subsequently improve its accuracy. Standardized procedures could also minimize the impact of these variables on studies results. The aim of this study was to propose a protocol as a checklist to standardize BIA procedures and produce comparable results from future studies performed with the classic hand-foot configuration in adults.

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese 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.

International Nuclear Information System (INIS)

A bioimpedance device (BIA) for evaluation of sarcopenia – age related muscle mass loss – is designed, developed and evaluated. The requirements were based on lightweight design, flexible and user enabled incorporation of measurement protocols and WiFi protocol for remote device control, full internet integration and fast development and usage of measurement protocols. The current design is based on usage of a microcontroller with integrated AD/DA converters. The prototype system was assembled and the operation and connectivity to different handheld devices and laptop computers was successfully tested. The designed BIA device can be accessed using TCP sockets and once the connection is established the data transfer runs successfully at the specified speed. The accuracy of currently developed prototype is about 5% for the impedance modulus and 5 deg. for the phase for the frequencies below 20 kHz with an unfiltered excitation signal and no additional amplifiers employed.

Bioelectrical impedance analysis in clinical practice: implications for hepatitis C therapy BIA and hepatitis C  

Directory of Open Access Journals (Sweden)

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 Thailand is a one of the nation in Southeast Asia, covered by numerous mangrove areas approximately 244,000 hectares. Phetchaburi province is the one of the province in Thailand where the mangrove area has been increasing continually since King’s Royally Initiated Laem Phak Bia Environmental Research and Development Project has been set up. The mangrove ecosystems functions are vital to the livelihood of the surrounding community. Laem Phak Bia community is one that has been served from mangrove ecosystem services. This study assessed the economic value of Laem Phak Bia mangrove ecosystem services in an area approximately 237.44 hectares using Participatory Economic Valuation (PEV by the villagers ranking and rating the importance of mangrove ecosystem services with a valuable thing for living that is the rice value. The results showed that this mangrove area was worth a total economic value about 100 million Baht per year or 424 thousand Baht per hectares per year. It could be divided into the value of regulation functions, production functions, habitat functions and information functions, which were about 38, 8, 25, and 29 million Baht per year, respectively.

Coproscopical investigations of the European otter (Lutra lutra) from Bia?owieza Primeval Forest.  

Science.gov (United States)

The parasitofauna of the European otter (Lutra lutra) remains poorly known in Poland. In the presented study 106 fecal samples from otters living in the Bia?owieza Primeval Forest were examined, using standard flotation and sedimentation methods. We found that the overall prevalence of parasitic infections was 30.1%. Eggs of Alaria alata (0.9%), Opistorchis or Metorchis sp. (5.7%), Diphyllobothrium latum (1.9%) and Aonchotheca putori (1.9%) were identified, but in other cases the species of parasite could not be reliably determined. Parasitological dissections should give better results in future studies. PMID:20707304

Thorough investigations on indoor radon in B?i?a radon-prone area (Romania)  

International Nuclear Information System (INIS)

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 differencethe cellar, the difference being statistically significant (t test, one tail, p 0.05). - Highlights: ? The annual average of indoor radon concentration for B?i?a area was 241 ± 178 Bq m?3. ? A large variability among rooms within surveyed dwellings was clearly evidenced. ? The radon concentrations in bedrooms without cellar were higher than above the cellar. ? The ratio between radon concentration at ground floor and cellar was calculated. ? A wide variation range between ground floor rooms and cellar was reported.

Evaluation of bioelectrical impedance analysis (BIA) to measure condition and energy allocated to reproduction in marine fishes  

Science.gov (United States)

Reliable estimates of fish energy density at specific times prior to spawning may provide suitable proxies for egg production, and thereby help to explain some of the observed annual variation in recruits per spawner. Our goal is to develop and test modifications of BIA technology to measure energy allocation to reproduction for a variety of marine fishes. To date, a newly developed measuring board and probe system stabilized readings, which was demonstrated by a significant reduction in the coefficients of variation for impedance measures. Total body water, wet and dry weights could be predicted with very good precision (r2 = 0.92-0.99) using BIA measures of reactance or resistance for a number of finfish species. While constituent relationships (e.g. body water- body mass functions) did not differ seasonally, we did find that BIA measures are sensitive to body composition changes related to the seasonal spawning cycle. In an examination of monthly samples of tilefish, phase angle decreased below 15° in post-spawning (regressed) females. Such a monthly trend, which suggests available energy had decreased following the spawning season, was not evident from other, more traditional measures of condition including body-muscle water content, Fulton's K or ordinal measures of fat deposition (such as mesenteric fat). These preliminary results show that BIA technology is a promising application for tracking and efficiently predicting energetic condition of marine fishes.

The use of bio-electrical impedance analysis (BIA) to guide fluid management, resuscitation and deresuscitation in critically ill patients: a bench-to-bedside review.  

Science.gov (United States)

The impact of a positive fluid balance on morbidity and mortality has been well established. However, little is known about how to monitor fluid status and fluid overload. This narrative review summarises the recent literature and discusses the different parameters related to bio-electrical impedance analysis (BIA) and how they might be used to guide fluid management in critically ill patients. Definitions are listed for the different parameters that can be obtained with BIA; these include among others total body water (TBW), intracellular water (ICW), extracellular water (ECW), ECW/ICW ratio and volume excess (VE). BIA allows calculation of body composition and volumes by means of a current going through the body considered as a cylinder. Reproducible measurements can be obtained with tetrapolar electrodes with two current and two detection electrodes placed on hands and feet. Modern devices also apply multiple frequencies, further improving the accuracy and reproducibility of the results. Some pitfalls and conditions are discussed that need to be taken into account for correct BIA interpretation. Although BIA is a simple, noninvasive, rapid, portable, reproducible, and convenient method of measuring body composition and fluid distribution with fewer physical demands than other techniques, it is still unclear whether it is sufficiently accurate for clinical use in critically ill patients. However, the potential clinical applications are numerous. An overview regarding the use of BIA parameters in critically ill patients is given, based on the available literature. BIA seems a promising tool if performed correctly. It is non-invasive and relatively inexpensive and can be performed at bedside, and it does not expose to ionising radiation. Modern devices have very limited between-observer variations, but BIA parameters are population-specific and one must be aware of clinical situations that may interfere with the measurement such as visible oedema, nutritional status, or fluid and salt administration. BIA can help guide fluid management, resuscitation and de-resuscitation. The latter is especially important in patients not progressing spontaneously from the Ebb to the Flow phase of shock. More research is needed in critically ill patients before widespread use of BIA can be suggested in this patient population. PMID:25432557

Hymenoscyphus subcarneus, a little known bryicolous discomycete found in the Bia?owie?a National Park  

Directory of Open Access Journals (Sweden)

Full Text Available he discomycete Hymenoscyphus subcarneus was found to grow parasitic on the liverwort Cephalozia catenulata in the Bia?owie?a National Park (Poland, and is described and illustrated from the fresh collection. Two characters, the ascus apical ring structure of the Calycina type and the contents of the living paraphyses (multiguttulate by low-refractive vacuolar bodies, have not been reported previously. In addition, a dried collection on Pohlia gracilis from Switzerland, Grimsel area, was studied. The relationship, taxonomy and infraspecific variation of the fungus are discussed. A new genus, Roseodiscus, is established to accomodate this bryicolous fungus together with two very similar equiseticolous species, Hymenoscyphus rhodoleucus and H. equisetinus. The three species are macroscopically characterized in the fresh state by a pale rosaceous-lilaceous hymenium and a mostly slender, concolorous or whitish stipe. Roseodiscus resembles Hymenoscyphus in various respects, but sharply deviates in the apical ring type which appears to indicate a more close relationship with genera like Calycina or Stamnaria. Rhizoscyphus ericae which forms a mycorrhiza with roots of Ericaceae, is compared with Roseodiscus. Based on vital observations of R. ericae this species is believed to be congeneric with the type of Pezoloma, P. griseum.

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.

Digital Repository Infrastructure Vision for European Research (DRIVER)

The paper presents the results of the 4-year studies on the influence of mowing on sedge communities structure in the near-edge zone and in the riverbed-adjacent zone of the Chwiszczej River valley (Bia?owie?a Forest). It was assumed that various habitat conditions in different parts of the valley could modify effects of mowing. The floristic richness of sedge dominated patches increases under the influence of mowing in both zones of the valley, mainly as a result of growing number of meado...

Post-fire macrofungi in the burnt area in the Jelonka reserve (Bia?owie?a region, NE Poland  

Directory of Open Access Journals (Sweden)

Full Text Available In the burnt area of the Jelonka nature reserve near Bia?owie?a Primeval Forest mycological studies were carried out in the years 1994-1999. Carpophores of all macrofungi were identified and counted on 7 permanent observation plots repesenting different successional stages before the fire. Altogether 250 species of macromycetes were found, among them 16 species of post-fire fungi. Pholiota carbonaria and Tephrocybe anthracophila were the most abundant and frequent species occurring in the first years after the fire. It has be~ revealed that the presence of carbonised substrate is a limiting factor for the occurrence of post-fire Basidiomycetes.

Coprological study on helminth fauna in Eurasian lynx (Lynx lynx) from the Bia?owieza Primeval Forest in eastern Poland.  

Science.gov (United States)

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

Body fluid volumes measurements by impedance: A review of bioimpedance spectroscopy (BIS) and bioimpedance analysis (BIA) methods.  

Science.gov (United States)

This paper reviews various bioimpedance methods permitting to measure non-invasively, extracellular, intracellular and total body water (TBW) and compares BIA methods based on empirical equations of the wrist-ankle resistance or impedance at 50 kHz, height and weight with BIS methods which rely on an electrical model of tissues and resistances measured at zero and infinite frequencies. In order to compare these methods, impedance measurements were made with a multifrequency Xitron 4200 impedance meter on 57 healthy subjects which had undergone simultaneously a Dual X-ray absorptiometry examination (DXA), in order to estimate their TBW from their fat-free-mass. Extracellular (ECW) and TBW volumes were calculated for these subjects using the original BIS method and modifications of Matthie[Matthie JR. Second generation mixture theory equation for estimating intracellular water using bioimpedance spectroscopy. J Appl Physiol 2005;99:780-1], Jaffrin et al.

For ECW, a good agreement was found between various BIS methods and that of Sergi while Hannan's values were higher. Both Matthie's and Moissl's methods gave mean TBW resistivities and volumes lower than those of Jaffrin's and DXA methods. Kushner et al. method gave values of TBW not significantly different from those of Jaffrin et al. and DXA, as Hannan's method in men, but Lukaski and Deurenberg methods led to an underestimation.

The Complete Genome of Propionibacterium freudenreichii CIRM-BIA1T, a Hardy Actinobacterium with Food and Probiotic Applications  

Science.gov (United States)

Background Propionibacterium freudenreichii is essential as a ripening culture in Swiss-type cheeses and is also considered for its probiotic use [1]. This species exhibits slow growth, low nutritional requirements, and hardiness in many habitats. It belongs to the taxonomic group of dairy propionibacteria, in contrast to the cutaneous species P. acnes. The genome of the type strain, P. freudenreichii subsp. shermanii CIRM-BIA1 (CIP 103027T), was sequenced with an 11-fold coverage. Methodology/Principal Findings The circular chromosome of 2.7 Mb of the CIRM-BIA1 strain has a GC-content of 67% and contains 22 different insertion sequences (3.5% of the genome in base pairs). Using a proteomic approach, 490 of the 2439 predicted proteins were confirmed. The annotation revealed the genetic basis for the hardiness of P. freudenreichii, as the bacterium possesses a complete enzymatic arsenal for de novo biosynthesis of aminoacids and vitamins (except panthotenate and biotin) as well as sequences involved in metabolism of various carbon sources, immunity against phages, duplicated chaperone genes and, interestingly, genes involved in the management of polyphosphate, glycogen and trehalose storage. The complete biosynthesis pathway for a bifidogenic compound is described, as well as a high number of surface proteins involved in interactions with the host and present in other probiotic bacteria. By comparative genomics, no pathogenicity factors found in P. acnes or in other pathogenic microbial species were identified in P. freudenreichii, which is consistent with the Generally Recognized As Safe and Qualified Presumption of Safety status of P. freudenreichii. Various pathways for formation of cheese flavor compounds were identified: the Wood-Werkman cycle for propionic acid formation, amino acid degradation pathways resulting in the formation of volatile branched chain fatty acids, and esterases involved in the formation of free fatty acids and esters. Conclusions/Significance With the exception of its ability to degrade lactose, P. freudenreichii seems poorly adapted to dairy niches. This genome annotation opens up new prospects for the understanding of the P. freudenreichii probiotic activity. PMID:20668525

The potential health hazard due to elevated radioactivity in old uranium mines in Dolina Bia?ego, Tatra Mountains, Poland.  

Science.gov (United States)

Natural radioactivity is one of the essential components of the environment. Unlike the Sudety mountains area in Poland, the Tatra Mountains were not the subject of wide survey as regards the levels of natural radioactivity. Especially, the concentrations of radon (natural radioactive gas) have not been investigated there in terms of their possible negative health impact. Within the frame of bilateral cooperation between the Institute of Nuclear Physics in Kraków, Poland, and the Jožef Stefan Institute in Ljubljana, Slovenia, the measurements of natural radioactive elements in old uranium mines in the Tatra National Park were performed in June 2010. The investigated sites were located in Dolina Bia?ego (The Valley of the White). One of the mines is situated near the tourist path. The paper presents the results of complex measurements of natural radioactivity in both uranium drifts. The concentration of radon gas inside the mining drifts exceeded 28,000 Bq m(-3). Also, very high gamma dose rates were observed (up to 5600 nSv h(-1)). The maximum concentrations of natural radioactive elements (potassium (40)K, radium (226)Ra, thorium (232)Th) in rock samples amounted to 535, 2137, and 18 Bq kg(-1), respectively. The effective dose rates due to radon and thoron inhalation have been assessed as 0.013 mSv h(-1) (for the lowest concentration) and 0.121 mSv h(-1) (for the highest concentration). PMID:23639059

Identification of operational clues to dry weight prescription in hemodialysis using bioimpedance vector analysis. The Italian Hemodialysis-Bioelectrical Impedance Analysis (HD-BIA) Study Group.  

Science.gov (United States)

In patients undergoing hemodialysis (HD) cyclic body fluid changes are estimated by body weight variations, which may be misleading. Conventional bioelectrical impedance analysis (BIA) produces biased estimates of fluids in HD due to the assumption of constant tissue hydration. We used an assumption-free assessment of hydration based on direct measurements of the impedance vector. The impedance vector (standard BIA at 50 kHz frequency) was measured in 1367 HD patients, ages 16 to 89 years with BMI 17 to 31 kg/m2, 1116 asymptomatic (680 M and 436 F), and 251 with recurrent HD hypotension (118 M and 133 F) before and after two HD sessions (thrice weekly bicarbonate dialysis, 210 to 240 min) removing 2.7 kg fluid. The vector distribution of HD patients was compared to 726 healthy subjects with the same age and BMI range. Individual vector measurements (resistance and reactance components) were plotted on the gender specific 50th, 75th and 95th percentiles of the vector distribution in the healthy population (reference tolerance ellipses) as a resistance-reactance graph (RXc graph). The wet-dry weight cycling of HD patients was represented on the resistance-reactance plane with a definite, cyclical, backward-forward displacement of the impedance vector. The vectors of patients with HD hypotension were less steep and more often shifted to the right, out of the reference 75% tolerance ellipse, than asymptomatic patients. A wet-dry weight prescription, based on BIA indications, would bring the vectors of patients back into the 75% reference ellipse, where tissue electrical conductivity is restored. Whether HD patients with vector cycling within the normal third quartile ellipse have better outcome awaits confirmation by longitudinal evaluation. PMID:9551415

Occurrence of fungi and fungus-like organisms in the Horodnianka River in the vicinity of Bia?ystok, Poland.  

Science.gov (United States)

Studies of fungi and fungus- like organisms in the northeastern Poland have mainly concentrated on running waters in the vicinity of Bia?ystok, including the Horodnianka River. The main objective was to investigate biodiversity of fungi and fungus-like organisms which take part in decomposition of organic matter commonly found in inland waters. To obtain a complete picture of species composition of fungi and fungus-like organisms in running waters we decided to explore representative sites of the Horodnianka River such as Olmonty, Hryniewicze and Horodniany with close localization of landfill. Fungal species were isolated using baiting technique. Baits of onion skin (Alium cepa), hemp-seeds (Cannabis sativa), impregnated cellophane and snake skin (Natrix natrix) were applied to isolate fungi from water of the Horodnianka River. The fungal community consists of 26 species, 10 species of fungi belonging to class Chytridiomycetes (3), anamorphic fungi (6), and Zygomycetes (1). 16 species belong to fungus-like organisms from class Oomycetes. Most of the recognized species have already been found in other running waters. From all the examined habitats the fungi belonging to 26 species of 18 genera Achlya, Alternaria, Aphanomyces, Aspergillus, Catenophlyctis, Dictyuchus, Fusarium, Karlingia, Lagenidium, Leptomitus, Olpidiopsis, Penicillium, Phlyctochytrium, Pythium, Saprolegnia, Scoliognia, Thraustotheca and Zoophagus were obtained. Certain fungal species like Aphanomyces laevis, Fusarium aqueductum, F. moniliforme, F. oxysporum, Leptomitus lacteus, Saprolegnia feax and S. parasitica were found at all the study sites. Among fungi potentially pathogenic and allergogenic for humans the genera Alternaria, Aspergillus, Fusarium, Lagenidium and Penicillium have already been described. However, the species Lagenidium giganteum and Achlya androgyna are new in the fungal biota of Poland. The greatest number of fungal species occurred in Olmonty (24), the smallest in Horodniany (13). Presence of fungi such as Leptomitus lacteus, Fusarium aqueductum in the water of the Horodnianka River offers the possibility of using them as indicators of water quality. PMID:22165737

Molecular dynamics of spin crossover: The (P, T) phase diagram of [Fe(PM-BIA){sub 2}(NCS){sub 2}  

Energy Technology Data Exchange (ETDEWEB)

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.

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

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

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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

The decomposition of plant litter fall in an oak-linden-hornbeam forest and an oak-pine mixed forest of the Bia?owie?a National Park  

Directory of Open Access Journals (Sweden)

Full Text Available The decomposition of hornbeam, linden and oak leaves in an oak-linden-hornbeam ,(Tilio-Carpinetum forst and of pine and spruce needles in an oak-pine mixed forest (Pino-Quercetum typicum of the Bia?owie?a National Park were studied. The decay of the hornbeam and linden leaves progressed at the same rates, while that of oak leaves was slower. During the first year in the oak-pine mixed forest, the decay of pine needles was more intense than that of spruce needles, then during later periods, the rate of decomposition of spruce needles exceeded that of pine. The initial rates of decomposition were determined by the C/N ratio and the content of easily soluble components in the starting materials. The decomposition rate coefficients were: 1.06 for hornbeam leaves, 0.91 for linden leaves, 0.63 for oak leaves, 0.21 for pine needles and 0.30 for spruce needles; the time necessary for 95%;, of the initial material to decay was from 3 to 5 years for the oak-linden-hornbeam forest and from 10 to 14 years in the oak-pine mixed forest. Elements can be arranged in the following orders on the basis of their rates of release: K> Mg > P> > Ca > N or K> Mg > Ca > P> N. A decisive role is played by microbiological processes in the release of nitrogen, phosphorus and calcium, while potassium and magnesium are released mainly by leaching.

Platinum, palladium and rhodium content in road dust, tunnel dust and common grass in Bia?ystok area (Poland): a pilot study.  

Science.gov (United States)

Automobile traffic is the main source of Pt, Pd and Rh, i.e. platinum-group elements (PGEs), contamination in urban areas and there is growing concern about the effects of these emerging contaminants for people living in these areas. PGE contents were determined in samples of road dust, tunnel dust and common grass as well as pine needles collected from the residential areas of Bia?ystok, northeast Poland. High resolution (HR) and quadrupole inductively coupled plasma mass spectrometry (ICP-MS) were compared for their adequacy in the environmental analysis of Pt and Rh. Palladium was determined by total X-ray fluorescence (TXRF) and HR-ICP-MS after matrix separation by reductive co-precipitation with Hg. The highest PGEs concentration was found in road dust samples. Platinum content in road dust varied from 34.2 to 110.9 ng g(-1), while that of Rh from 6.0 to 19.7 ng g(-1). The mean concentration of Pd in this matrix was 32.8 ng g(-1) as determined by TXRF analysis and 42.2 ng g(-1) by HR-ICP-MS. The highest Pt concentration in tunnel dust was found in the size fraction below 75 microm (22.3-23.3 ng g(-1)). The mean concentrations of PGEs in grass were 8.63 ng g(-1) for Pt, 0.65 ng g(-1) for Rh and 3.2 ng g(-1) for Pd. The concentration of PGEs in pine needles was below the limits of detection of the methods used. PMID:15050388

Generalized GHY term for f(R) Gravity  

CERN Document Server

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

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

Scientific Electronic Library Online (English)

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

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

Science.gov (United States)

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

Full Text Available Introduction: Ovarian cancer takes fourth place as a cause of death from all cancers and first place fromgynaecological malignancies in Poland. Recent investigations have noted the prognostic significance of proteinslinked with proliferation (Ki-67 and apoptosis (CAS – cellular apoptosis susceptibility protein.The aim of the study was to evaluate the immunoexpression of CAS and Ki-67 proteins in metastatic andnon-metastatic serous ovarian tumours, as well as to find possible relationships between this immunoexpressionand tumour proliferation activity. Material and methods: The analysis comprised 43 women diagnosed and treated for malignant epithelialovarian tumours. The immunoexpression of CAS protein was assessed semiquantitatively, whereas immunoexpressionof Ki-67 was performed using a computer image analysis system. Results: The immunoexpression of both CAS and Ki-67 proteins was significantly increased in the metastaticgroup as compared with patients without metastases. Also, a positive correlation was found between immunoexpressionof Ki-67 and CAS protein, but this correlation was not significant. Conclusions: In conclusion, our data suggest that increased immunoexpression of CAS and Ki-67 proteins inserous ovarian tumours may be helpful in identifying cases of higher metastatic potential.

Science.gov (United States)

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

Functional survey for heterologous sugar transport proteins, using Saccharomyces cerevisiae as a host.  

Science.gov (United States)

Molecular transport is a key process in cellular metabolism. This step is often limiting when using a nonnative carbon source, as exemplified by xylose catabolism in Saccharomyces cerevisiae. As a step toward addressing this limitation, this study seeks to characterize monosaccharide transport preference and efficiency. A group of 26 known and putative monosaccharide transport proteins was expressed in a recombinant Saccharomyces cerevisiae host unable to transport several monosaccharides. A growth-based assay was used to detect transport capacity across six different carbon sources (glucose, xylose, galactose, fructose, mannose, and ribose). A mixed glucose-and-xylose cofermentation was performed to determine substrate preference. These experiments identified 10 transporter proteins that function as transporters of one or more of these sugars. Most of these proteins exhibited broad substrate ranges, and glucose was preferred in all cases. The broadest transporters confer the highest growth rates and strongly prefer glucose. This study reports the first molecular characterization of the annotated XUT genes of Scheffersomyces stipitis and open reading frames from the yeasts Yarrowia lipolytica and Debaryomyces hansenii. Finally, a phylogenetic analysis demonstrates that transporter function clusters into three distinct groups. One particular group comprised of D. hansenii XylHP and S. stipitis XUT1 and XUT3 demonstrated moderate transport efficiency and higher xylose preferences. PMID:21421781

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

Science.gov (United States)

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

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

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

Science.gov (United States)

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

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

Energy Technology Data Exchange (ETDEWEB)

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.

Agreement of bioelectric impedance analysis and dual-energy X-ray absorptiometry for body composition evaluation in adults with cystic fibrosis.  

Science.gov (United States)

Malnutrition in cystic fibrosis (CF) is associated with increased mortality and can lead to fat-free (FFM) and fat mass (FM) loss. Dual-energy X-ray absorptiometry (DXA) is used and validated to measure FFM and FM. DXA's high cost has led to the utilization of less costly techniques such as bioelectrical impedance analysis (BIA). The aim of this study was to determine the agreement of FFM, FM and %FM measurements taken with DXA and BIA in adults with CF. We measured FFM, FM and %FM in 34 adults with CF with a leg-to-leg BIA and an iDXA and determined agreement using Bland-Altman analysis. While DXA and BIA measurements were well correlated (r > 0.8), mean biases between both methods were between 8 and 11%. BIA underestimated FM and %FM and overestimated FFM. In a clinical research setting where these measurements are used to phenotype patients, BIA cannot replace DXA. PMID:24522087

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

Guidelines for conducting pharmaceutical budget impact analyses for submission to public drug plans in Canada.  

Science.gov (United States)

Until now, there has been no standardized method of performing and presenting budget impact analyses (BIAs) in Canada. Nevertheless, most drug plan managers have been requiring this economic data to inform drug reimbursement decisions. This paper describes the process used to develop the Canadian BIA Guidelines; describes the Guidelines themselves, including the model template; and compares this guidance with other guidance on BIAs. The intended audience includes those who develop, submit or use BIA models, and drug plan managers who evaluate BIA submissions. The Patented Medicine Prices Review Board (PMPRB) initiated the development of the Canadian BIA Guidelines on behalf of the National Prescription Drug Utilisation Information System (NPDUIS). The findings and recommendations from a needs assessment with respect to BIA submissions were reviewed to inform guideline development. In addition, a literature review was performed to identify existing BIA guidance. The detailed guidance was developed on this basis, and with the input of the NPDUIS Advisory Committee, including drug plan managers from multiple provinces in Canada and a representative from the Canadian Agency for Drugs and Technologies in Health. A Microsoft Excel-based interactive model template was designed to support BIA model development. Input regarding the guidelines and model template was sought from each NPDUIS Advisory Committee member to ensure compatibility with existing drug plan needs. Decisions were made by consensus through multiple rounds of review and discussion. Finally, BIA guidance in Canadian provinces and other countries were compared on the basis of multiple criteria. The BIA guidelines consist of three major sections: Analytic Framework, Inputs and Data Sources, and Reporting Format. The Analytic Framework section contains a discussion of nine general issues surrounding BIAs (model design, analytic perspective, time horizon, target population, costing, scenarios to be compared, the characterisation of uncertainty, discounting, and validation methods). The Inputs and Data Sources section addresses methods for market size estimation, comparator selection, scenario forecasting and drug price estimation. The Reporting Format section describes methods for BIA reporting. The new Canadian BIA Guidelines represent a significant departure from the limited guidance that was previously available from some of the provinces, because they include specific details of the methods of performing BIAs. The Canadian BIA Guidelines differ from the Principles of Good Research Practice for BIAs developed by the International Society for Pharmacoeconomic and Outcomes Research (ISPOR), which provide more general guidance. The Canadian BIA Guidelines and template build upon existing guidance to address the specific requirements of each of the participating drug plans in Canada. Both have been endorsed by the NPDUIS Steering Committee and the PMPRB for the standardization of BIA submissions. PMID:18489199

Nutritional and hydration status in elderly subjects: clinical rating versus bioimpedance analysis.  

Science.gov (United States)

Malnutrition and dehydration are common in elderly. A simple, reliable instrument to assess nutritional and hydration status would be very helpful. Bioelectrical impedance analysis (BIA) has been promising in this context, but data of elderly persons and geriatric in-hospital patients are rare. Therefore, we first compared BIA measurements (resistance, reactance, phase angle and a resulting vectorgraph) with a clinical assessment in 31 community-dwelling women and 30 female nursing-home residents. The results of the BIA measurement correlated well to weight, hand grip strength, and calf circumference. We then compared BIA measurements with clinical judgement of hydration status in 103 acute geriatric hospital in-patients. Concordance between the results of clinical judgement and BIA measurements was only 43.7%. In assessing geriatric in-patients, there is little concordance between the clinical and the bioelectrical evaluation of the hydration status. PMID:19616321

Bioelectrical impedance analysis. What does it measure?  

Science.gov (United States)

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

The Bland-Altman plot showed no agreement for FFM, FM or TBW between data provided by BIA and DDM. The linear regression models proposed in our study with respect to FFM, FM, and TBW were well adjusted. FFM obtained by DDM = 0.842 x FFM obtained by BIA. FM obtained by DDM = 0.855 x FM obtained by BIA + 0.152 x weight (kg. TBW obtained by DDM = 0.813 x TBW obtained by BIA. The body composition results of obese adolescents determined by DDM can be predicted by using the measures provided by BIA through a regression equation.

Earthquake risk mitigation projects in central asia and india  

Science.gov (United States)

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

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

DEFF Research Database (Denmark)

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

Validity of bioelectrical impedance measurement in predicting fat-free mass of chinese children and adolescents.  

Science.gov (United States)

Background The current study aimed to examine the validity of various published bioelectrical impedance analysis (BIA) equations in estimating FFM among Chinese children and adolescents and to develop BIA equations for the estimation of fat-free mass (FFM) appropriate for Chinese children and adolescents. Material and Methods A total of 255 healthy Chinese children and adolescents aged 9 to 19 years old (127 males and 128 females) from Tianjin, China, participated in the BIA measurement at 50 kHz between the hand and the foot. The criterion measure of FFM was also employed using dual-energy X-ray absorptiometry (DEXA). FFM estimated from 24 published BIA equations was cross-validated against the criterion measure from DEXA. Multiple linear regression was conducted to examine alternative BIA equation for the studied population. Results FFM estimated from the 24 published BIA equations yielded high correlations with the directly measured FFM from DEXA. However, none of the 24 equations was statistically equivalent with the DEXA-measured FFM. Using multiple linear regression and cross-validation against DEXA measurement, an alternative prediction equation was determined as follows: FFM (kg)=1.613+0.742×height (cm)2/impedance (?)+0.151×body weight (kg); R^2=0.95; SEE=2.45kg; CV=6.5, 93.7% of the residuals of all the participants fell within the 95% limits of agreement. Conclusions BIA was highly correlated with FFM in Chinese children and adolescents. When the new developed BIA equations are applied, BIA can provide a practical and valid measurement of body composition in Chinese children and adolescents. PMID:25398209

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

Directory of Open Access Journals (Sweden)

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

As análises da Curva ROC indicaram os seguintes %GCT-BIA que identificaram excesso de GV: homens: 21,5% (adultos, 24,25% (idosos; mulheres: 35,05% (adultas, 38,45% (idosas, com sensibilidade de 78,6%, 82,1%, 83,3%, 66,7% e especificidade de 70,6%, 62,5%, 79,1%, 69%, respectivamente. CONCLUSÃO: BIA apresentou satisfatória sensibilidade e especificidade para predizer GV, entretanto, outros aparelhos e técnicas devem ser investigados para melhorar essa predição.OBJECTIVE: To evaluate the association between electrical bioimpedance analysis (BIA and visceral fat (VF in adult and elderly patients. SUBJECTS AND METHODS: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly stratified by sex, age and body mass. Computerized tomography (VF area and BIA (percentage of total body fat (%TBF-BIA, phase angle, reactance and resistance data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. RESULTS: VF areas > 130 cm² 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.

Agreement of bioelectrical impedance with dual-energy X-ray absorptiometry and MRI to estimate changes in body fat, skeletal muscle and visceral fat during a 12-month weight loss intervention.  

Science.gov (United States)

The aim of the present study was to analyse the agreement of bioelectrical impedance analysis (BIA) compared with dual-energy X-ray absorptiometry (DXA) and MRI in estimating body fat, skeletal muscle and visceral fat during a 12-month weight loss intervention. A total of nineteen obese adults (twelve females, seven males) aged 20·2-48·6 years, mean BMI 34·6 (SE 0·6) kg/m², participated in the study. Body fat, skeletal muscle and visceral fat index were measured by BIA (Omron BF-500; Omron Medizintechnik) and compared with DXA (body fat and skeletal muscle) at baseline, 5 and 12 months, and with MRI (visceral fat) at baseline and 5 months. The subjects lost 8·9 (SE 1·8) kg (9·0 (SE 1·7) %) of body weight during the 12-month intervention. BIA, as compared to DXA, accurately assessed loss of fat (7·0 (SE 1·5) v. 7·0 (SE 1·4) kg, P= 0·94) and muscle (1·0 (SE 0·2) v. 1·4 (SE 0·3) kg, P= 0·18). While body fat was similar by the two methods, skeletal muscle was underestimated by 1-2 kg using BIA at each time point. Compared to MRI, BIA overestimated visceral fat, especially in males. BIA and DXA showed high correlations for kg fat, both cross-sectionally and longitudinally (r 0·91-0·99). BIA, compared with DXA and MRI, detected kg muscle and visceral fat more accurately cross-sectionally (r 0·77-0·87 and r 0·40-0·78, respectively) than their changes longitudinally (r 0·24-0·61 and r 0·46, respectively). BIA is at its best when assessing the amount or changes in fat mass. It is a useful method for measuring skeletal muscle, but limited in its ability to measure visceral fat. PMID:22935366

We describe the case of an obese patient presenting leg oedema, progressive oliguria, orthopnoea and mild increased B-type natriuretic peptide (BNP) levels. Bioimpedance analysis (BIA) provided additional data for the interpretation of the plasma BNP values, contributing to the diagnosis of heart failure and the appropriate management of the patient. In our mind, BIA could represent a useful tool for integrating the plasma BNP assay in both diagnosis and management of heart failure. PMID:16869461

A Comparison Study of Portable Foot-to-Foot Bioelectrical Impedance Scale to Measure Body Fat Percentage in Asian Adults and Children  

Science.gov (United States)

Objective. To compare the measurements of body fat percentage (BF%) using the foot-to-foot bioelectrical impedance analysis (FTF-BIA) with the direct segmental multifrequency BIA (DSM-BIA). Methods. There were 36 men and 52 women (37.1 ± 14.3 years) with 57% Malays, 30% Chinese, and 13% Indian. For children, there were 45 boys and 26 girls (11.5 ± 2.5 years) with 52% Malay, 15% Chinese, and 33% Indian. Results. Mean height for men was 168.4?cm, 11?cm taller than women. Men were 10?kg heavier than women at 70?kg. BF% in women was 32% and 33% whereas BF% in men was 23% and 25% when measured using FTF-BIA and DSM-BIA, respectively. In children, BF% measured with FTF-BIA and DSM-BIA was 49% and 46%, respectively. The correlations were significant for men (r = 0.92, SEE = 2.80), women (r = 0.91, SEE = 3.31), boys (r = 0.95, SEE = 5.44), and girls (r = 0.96, SEE = 5.27). The BF% in underweight/normal (r = 0.92, SEE = 2.47) and that in overweight/obese adults (r = 0.89, SEE = 3.61) were strongly correlated. The correlations were significant in normal/underweight (r = 0.94, SEE = 3.78) and obese/overweight children (r = 0.83, SEE = 6.49). All ethnic groups showed significant correlation with BF%. Malay adults (r = 0.92, SEE = 3.27) and children (r = 0.94, SEE = 0.88) showed significant mean differences in BF%. Conclusion. The FTF-BIA showed higher accuracy for all normal/underweight and Chinese group with acceptable overestimation in children and underestimation in adults. Caution should be taken when interpreting BF% depending on gender, BMI, and ethnicity. PMID:25258711

Is bioelectrical impedance accurate for use in large epidemiological studies?  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Percentage of body fat is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. Bioelectrical impedance analysis (BIA is a relatively simple, quick and non-invasive technique, to measure body composition. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. In large epidemiologic studies simpler surrogate techniques such as body mass index (BMI, waist circumference, and waist-hip ratio are frequently used instead of BIA to measure body fatness. We reviewed the rationale, theory, and technique of recently developed systems such as foot (or hand-to-foot BIA measurement, and the elements that could influence its results in large epidemiologic studies. BIA results are influenced by factors such as the environment, ethnicity, phase of menstrual cycle, and underlying medical conditions. We concluded that BIA measurements validated for specific ethnic groups, populations and conditions can accurately measure body fat in those populations, but not others and suggest that for large epdiemiological studies with diverse populations BIA may not be the appropriate choice for body composition measurement unless specific calibration equations are developed for different groups participating in the study.

Bioelectrical impedance and visceral fat: a comparison with computed tomography in adults and elderly  

International Nuclear Information System (INIS)

Objective: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. Subjects and methods: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. Results: VF areas ? 130 cm2 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)

Seasonal and geographical variation of Linke turbidity factor and its effect on global horizontal irradiance estimation: UAE case study  

Science.gov (United States)

In a clear-sky condition, solar radiation travelling through the Earth's atmosphere encounters atmospheric attenuation caused by several factors. Scattering of solar radiation is mainly caused by air molecules, water vapor, water droplets and dust. On the other hand, the absorption of solar radiation is usually related to the presence of O3, water vapor and CO2 layers in the upper atmosphere. Linke turbidity factor (TL) is commonly used to model the attenuation of solar radiation in the atmosphere. TL is the key parameter used in the Heliosat model, which is developed to estimate the global horizontal irradiance (GHI) at the surface of the earth. TL is calculated by the following equation: T_L=?/?_R where ? is the optical thickness of the whole atmosphere, and ?R is the optical thickness of the Rayleigh atmosphere, i.e. the clear and dry atmosphere. The problem with TL is its dependence on the air mass (m). Therefore, TL is normalized to an air mass of 2 in order to reduce the daily variance. In this study, the monthly TL(m=2) is computed over 7 ground-based stations available in the UAE (figure 1). Spatial and temporal analysis was performed to assess the seasonal and the geographical distribution of TL over the UAE. The computed TL(m=2) values are then applied in the Heliosat model to compare between the measured and modeled GHI values. The model treats the atmospheric and cloud transmittances separately. First, clear-sky direct normal irradiance (DNI) and diffused horizontal irradiance (DHI) values are computed using TL(m=2), solar zenith angle, air mass, sun-earth distance correction, solar constant and the Rayleigh optical depth, from that the clear-sky GHI is determined. Next, the cloud index is derived from the HRV channel available from the SEVIRI instrument, and from that the cloud transmission is computed. The product of the cloud transmission and the clear-sky GHI produces the modeled GHI. The comparison between TL calculated over the seven stations show higher turbidity for the 4 inland stations (stations 4-7) in the summer compared to coastal and near-coastal stations (stations 1-3). This difference could be explained by the high dust generation in desert areas surrounding inland stations, in summer dry and hot weather. A preliminary comparison has been performed between the modeled and the measured GHI values over four inland stations (stations 4-7). The obtained results show RMSE and r2 values ranging between 16.7-18% and 0.95-0.96, respectively.

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

Energy Technology Data Exchange (ETDEWEB)

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

Health workforce responses to global health initiatives funding: a comparison of Malawi and Zambia  

Directory of Open Access Journals (Sweden)

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.

Development of bioelectrical impedance analysis-based equations for estimation of body composition in postpartum rural Bangladeshi women.  

Science.gov (United States)

Equations for predicting body composition from bioelectrical impedance analysis (BIA) parameters are age-, sex- and population-specific. Currently there are no equations applicable to women of reproductive age in rural South Asia. Hence, we developed equations for estimating total body water (TBW), fat-free mass (FFM) and fat mass in rural Bangladeshi women using BIA, with ²H?O dilution as the criterion method. Women of reproductive age, participating in a community-based placebo-controlled trial of vitamin A or ?-carotene supplementation, were enrolled at 19·7 (SD 9·3) weeks postpartum in a study to measure body composition by ²H?O dilution and impedance at 50 kHz using multi-frequency BIA (n 147), and resistance at 50 kHz using single-frequency BIA (n 82). TBW (kg) by ²H2O dilution was used to derive prediction equations for body composition from BIA measures. The prediction equation was applied to resistance measures obtained at 13 weeks postpartum in a larger population of postpartum women (n 1020). TBW, FFM and fat were 22·6 (SD 2·7), 30·9 (SD 3·7) and 10·2 (SD 3·8) kg by ²H?O dilution. Height²/impedance or height²/resistance and weight provided the best estimate of TBW, with adjusted R² 0·78 and 0·76, and with paired absolute differences in TBW of 0·02 (SD 1·33) and 0·00 (SD 1·28) kg, respectively, between BIA and ²H?O. In the larger sample, values for TBW, FFM and fat were 23·8, 32·5 and 10·3 kg, respectively. BIA can be an important tool for assessing body composition in women of reproductive age in rural South Asia where poor maternal nutrition is common. PMID:22716500

Comparison of two field methods for estimating body fat in different spanish dance disciplines.  

Science.gov (United States)

The purpose of the present study was to investigate percentage body fat (%BF) differences in three Spanish dance disciplines and to compare skinfold and bioelectrical impedance predictions of body fat percentage in the same sample. Seventy-six female dancers, divided into three groups, Classical (n=23), Spanish (n=29) and Flamenco (n=24), were measured using skinfold measurements at four sites: triceps, subscapular, biceps and iliac crest, and whole body multi-frequency bioelectrical impedance (BIA). The skinfold measures were used to predict body fat percentage via Durnin and Womersley's and Segal, Sun and Yannakoulia equations by BIA. Differences in percent fat mass between groups (Classical, Spanish and Flamenco) were tested by using repeated measures analysis (ANOVA). Also, Pearson's product-moment correlations were performed on the body fat percentage values obtained using both methods. In addition, Bland-Altman plots were used to assess agreement, between anthropometric and BIA methods. Repeated measures analysis of variance did not found differences in %BF between modalities (panalysis revealed differences between BIA Yannakoulia as a reference method with BIA Segal (-0.35 ± 2.32%, 95%CI: -0.89to 0.18, p=0.38), with BIA Sun (-0.73 ± 2.3%, 95%CI: -1.27 to -0.20, p=0.014) and Durnin-Womersley (-2.65 ± 2,48%, 95%CI: -3.22 to -2.07, p<0.0001). It was concluded that body fat percentage estimates by BIA compared with skinfold method were systematically different in young adult female ballet dancers, having a tendency to produce underestimations as %BF increased with Segal and Durnin-Womersley equations compared to Yannakoulia, concluding that these methods are not interchangeable.

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

Science.gov (United States)

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

Yet, paralogs of GH in suckers are more than 90% conserved in nucleotide (nt and amino acid (aa sequence. Within paralogs across species, variation in nt and aa sequence averages 3.33% and 4.46% for GHI, and 3.22% and 2.43% for GHII, respectively. Selection tests suggest that the two GH paralogs are under strong purifying selection. Consensus trees from phylogenetic analysis of GH coding region data for 23 species of suckers, other cypriniform fishes and outgroups resolved cypriniform relationships and relationships among GHI sequences of suckers more or less consistently with analyses based on other molecular data. However, the analysis failed to resolve all sucker GHI and GHII sequences as monophyletic sister groups. This unexpected topology did not differ significantly from topologies constrained to make all GH sequences monophyletic. We attribute this result either to limitations in our GHII data set or convergent adaptive changes in GHII of tribe Catostomini.

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Uma nova apresentação da insensibilidade ao hormônio de crescimento (IGH), causada por mutações em homozigose no gene STAT5B (transdutor de sinal e ativador de transcrição tipo 5B), foi caracterizada nos últimos anos. Sua particularidade é a associação com quadros de disfunção imunológica grave, sen [...] do o mais característico a pneumonite intersticial linfocítica. A presença concomitante de doenças crônicas imunológicas pode fazer com que a baixa estatura seja erroneamente considerada uma consequência do quadro clínico, levando ao subdiagnóstico dessa forma de IGH. O objetivo desta revisão é divulgar o conhecimento atual sobre essa rara patologia, facilitando o reconhecimento de pacientes com IGH secundária a mutações no gene STAT5B em ambulatórios de endocrinologia e de outras especialidades. Abstract in english A new presentation of growth hormone insensitivity (GHI) caused by homozygous mutations in STAT5B (signal transducer and activator of transcription 5B) gene has been characterized in the last years. Its particularity is the association with severe immune dysfunction, especially with lymphocytic inte [...] rstitial pneumonitis. This may mislead physicians into considering short stature as secondary to chronic immunological disease and consequently into underdiagnosing this form of GHI. The objective of this review is to propagate current knowledge about this rare pathology, facilitating the diagnosis of patients with GHI due to STAT5B mutations in endocrinology and other specialties clinics.

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

International Nuclear Information System (INIS)

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

Cis association of leukocyte Ig-like receptor 1 with MHC class I modulates accessibility to antibodies and HCMV UL18.  

Science.gov (United States)

Leukocyte Ig-like receptor (LIR) 1 (CD85j/ILT2/LILRB1) is an inhibitory receptor with broad specificity for MHC class I (MHC-I) and the human CMV MHC-I homologue UL18. LIR-1 can inhibit NK cells through the conventional interaction with MHC-I expressed on a target cell (in trans) but the nature and the effects of LIR-1 interactions with MHC-I in cis are not well understood. Here we show that MHC-I expressed in cis has an impact on the detection of LIR-1 with various antibodies. We found the cis interaction alters recognition by only one of two antibodies known to block functional trans recognition by LIR-1 on NK cells. Specifically, we observed an enhancement of recognition with GHI/75 in the presence of various MHC-I alleles on 721.221 cells. We found that blocking the LIR-1 contact site with anti-MHC-I antibodies decreased detection of LIR-1 with GHI/75. We also observed a decrease in GHI/75 following acid denaturation of MHC-I. Finally, disruption of LIR-1 cis interactions with MHC-I significantly enhanced UL18-Fc binding to NK92 cells and enhanced the relative inhibition of NK92 cells by HLA-G. These results have implications for LIR-1 function in scenarios such as infection when MHC-I levels on effector cells may be increased by IFNs. PMID:23348966

Surface Radiation from GOES: A Physical Approach; Preprint  

Energy Technology Data Exchange (ETDEWEB)

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

Body composition by bioelectrical impedance analysis in children below 7 years old  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose : Body composition is important to define and manage obesity and undernutrition. Obesity is a significant health problem with medical and psychological consequences for children and adolescents. Body composition analysis (BIA is a simple, rapid, noninvasive, and reproducible technique. However, comparative analysis of body composition has not been done in young children below 7 years old. The aim of this study is to estimate antropometric data and body composition by BIA, and to investigate the correlation between anthropometric data and fat mass or fat percent in young children. Methods : We measured height, weight, body mass index (BMI, fat mass, and fat percent by BIA in 1,376 children aged 3&#8211;6 years of whom 688 were males and 688 were females. Results : Fat mass, fat percent, intracellular fluid, extracellular fluid, protein, and minerals were significantly higher in the obese group. A significant positive correlation exists between fat mass and BMI or weight. A significant positive linear correlation was also noted between fat percent and BMI. Protein, weight, fat mass, and fat percent were significantly different among groups. Conclusion : BIA is an objective, accurate method to estimate body fat in childhood obesity cases. Fat mass and fat percent data acquired by using BIA highly correlated with BMI. However, a large-scale study is needed to diagnose obesity in young children.

Role of the phloem in the biochemistry and ecophysiology of benzylisoquinoline alkaloid metabolism.  

Science.gov (United States)

Benzylisoquinoline alkaloids (BIAs) are a diverse group of biologically active specialized metabolites produced mainly in four plant families. BIA metabolism is likely of monophyletic origin and involves multiple enzymes yielding structurally diverse compounds. Several BIAs possess defensive properties against pathogenic microorganisms and herbivores. Opium poppy (Papaver somniferum: Papaveraceae) has emerged as a model system to investigate the cellular localization of BIA biosynthesis. Although alkaloids accumulate in the laticifer cytoplasm (latex) of opium poppy, corresponding biosynthetic enzymes and gene transcripts are localized to proximal sieve elements and companion cells, respectively. In contrast, BIA metabolism in the non-laticiferous meadow rue (Thalictrum flavum; Ranunculaceae) occurs independent of the phloem. Evidence points toward the adoption of diverse strategies for the biosynthesis and accumulation of alkaloids as defensive compounds. Recruitment of cell types involved in BIA metabolism, both within and external to the phloem, was likely driven by selection pressures unique to different taxa. The biochemistry, cell biology, ecophysiology, and evolution of BIA metabolism are considered in this context. PMID:23781223

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 indis advantage is most pronounced in individuals with particularly low V-dotO2max

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.

Non-magnetic semiconductor spin transistor  

CERN Document Server

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

SUJEITOS E MÉTODOS: Estudo transversal, 191 indivíduos (52% mulheres, 49% idosos), estratificados por sexo, grupo etário e massa corporal. Obtiveram-se dados sobre tomografia computadorizad [...] a (área de GV) e BIA (percentual de gordura corporal total (%GCT-BIA), ângulo de fase, reactância e resistência). Análise estatística: Coeficiente de Correlação de Pearson, Anova, Qui-quadrado de Pearson, Curva ROC. RESULTADOS: Áreas de GV > 130 cm² foram mais observadas em idosos e em homens. Entre as mulheres adultas, mostrou-se correlação mais forte entre GV e %GCT-BIA. Os demais grupos apresentaram resultados semelhantes e correlações estatisticamente significantes. As correlações entre GV e ângulo de fase foram fracas e sem significância estatística. As análises da Curva ROC indicaram os seguintes %GCT-BIA que identificaram excesso de GV: homens: 21,5% (adultos), 24,25% (idosos); mulheres: 35,05% (adultas), 38,45% (idosas), com sensibilidade de 78,6%, 82,1%, 83,3%, 66,7% e especificidade de 70,6%, 62,5%, 79,1%, 69%, respectivamente. CONCLUSÃO: BIA apresentou satisfatória sensibilidade e especificidade para predizer GV, entretanto, outros aparelhos e técnicas devem ser investigados para melhorar essa predição. Abstract in english OBJECTIVE: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. SUBJECTS AND METHODS: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized [...] tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. RESULTS: VF areas > 130 cm² 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.

Body proportions in three Nigerian tribes.  

Science.gov (United States)

Prediction equations of body composition based on measurements of whole-body bioelectrical impedance analysis (BIA) have been found to be population-specific. It was hypothesised that this may be, in part, due to differences in proportional limb lengths between ethnic or racial groups. As a preliminary to a survey of body composition in urban Nigerians using BIA, the relative limb lengths of the three major tribal groups (Hausa, Yoruba and Ibo) were determined. We found small (5-9%) but significantly longer limb lengths in Nigerians compared to a Caucasian population, but no significant differences between tribes. This implies that BIA prediction equations generated in a Caucasian population are inappropriate for use in a Nigerian population. PMID:14618504

Bioelectrical impedance analysis as a laboratory activity: At the interface of physics and the body  

Science.gov (United States)

We present a novel laboratory activity on RC circuits aimed at introductory physics students in life-science majors. The activity teaches principles of RC circuits by connecting ac-circuit concepts to bioelectrical impedance analysis (BIA) using a custom-designed educational BIA device. The activity shows how a BIA device works and how current, voltage, and impedance measurements relate to bioelectrical characteristics of the human body. From this, useful observations can be made including body water, fat-free mass, and body fat percentage. The laboratory is engaging to pre-health and life-science students, as well as engineering students who are given the opportunity to observe electrical components and construction of a commonly used biomedical device. Electrical concepts investigated include alternating current, electrical potential, resistance, capacitance, impedance, frequency, phase shift, device design, and the use of such topics in biomedical analysis.

Twenty-five subjects, divided in homogenous groups according to age (18 to 36 years, sex (men, and race (white participated in the study. BIA measures were taken using the Lukaski et al. standardization (1985,1986. ST was taken by using the equation of 3 and 7 skinfolds (Jackson, Pollock, 1978. The values of %BF and residual volume for the UW were estimated by the Siri (1961 and Goldman and Becklake (1959 equations. Statistical analysis was calculated by: a repeated measures ANOVA followed by the Tukey post-hoc test; b Pearson (r correlation; c standard error of estimate (SEE of the BIA and ST compared to UW. The results indicated that: a there were no significant differences for %BF measures obtained by the BIA devices; b the %BF obtained by the A-310 and BF-906 devices did not match with the UW measures (p < 0.01; c SEE was high for all devices, except for the RJL-101; d the correlation coefficients were low to moderate for all devices, the BF-906 showing the higher values; e The ST showed greater values of r and fewer SEE than the BIA. In conclusion, the findings do not allow to state that a BIA device is better than the others to assess %BF, but the ST seems to be more powerful and reliable than the BIA for %BF estimation. Notwithstanding, the results should be confirmed by more sophisticated experimental designs, with a closer control of sampling bias for type I and II errors.

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

Reliability of non-lethal assessment methods of body composition and energetic status exemplified by applications to eel (Anguilla anguilla) and carp (Cyprinus carpio)  

DEFF Research Database (Denmark)

tNon-lethal assessments of proximate body composition of fish can help unravelling the physiologicaland condition-dependent mechanisms of individual responses to ecological challenges. Common non-lethal methods designed to index nutrient composition in fish include the relative condition factor (Kn),bioelectric impedance-based assessments of body composition (BIA), and microwave-based “fat” meters(FM). Previous studies have revealed mixed findings as to the reliability of each of these. We compared theperformance of Kn, BIA and FM at different temperatures to predict energetic status of the whole bodiesof live eel (Anguilla anguilla) and carp (Cyprinus carpio) and the dorsal white muscle of carp. Homogenizedfish flesh was used for calibration. Relative dry mass was strongly correlated with relative fat content(R2up to 96.7%) and energy density (R2up to 99.1%). Thus, calibrations were only conducted for relativedry mass as an index of energetic status of a fish. FM readings were found to predict relative dry mass ofwhole body in eel (R2= 0.707) and carp (R2= 0.676), and dorsal white muscle of carp (R2= 0.814) well. Bycontrast, BIA measurements and Knwere much less suited to identify variation in relative dry mass. BIA-based models were also temperature-dependent. As a result, a regression model calibrated at 10?C andapplied to BIA measurements at 20?C was found to underestimate energetic status of a fish. By contrast,no effects of temperature on FM calibration results were found. Based on our study, the FM approach isthe most suitable method to non-lethally estimate energetic status in both, carp and eel, whereas BIA is oflimited use for energetic measurements in the same species, in contrast to other reports in the literature

Microcystin assimilation and detoxification by Daphnia spp. in two ecosystems of different cyanotoxin concentrations  

Directory of Open Access Journals (Sweden)

Full Text Available Microcystins (MCs, the main group of cyanotoxins, can induce oxidative stress in the cells of aquatic animals. This study evaluated the sensitivity of daphniids – from two ecosystems characterised by different trophic states and habitat levels of cyanobacteria abundance – to microcystin toxicity by analysing oxidative stress parameters and MC detoxification ability. As a study site, we chose the eutrophic Sulejow reservoir, which has regular annual toxic cyanobacterial blooms, and the mesotrophic lake Bia?e, where low abundances of cyanobacteria have only recently appeared. We found much higher accumulations of MCs in tissues of Daphnia spp. in lake Bia?e, despite low toxin concentrations in this ecosystem compared with the Sulejow reservoir. Simultaneously, high levels of lipid peroxidation (LPO and a significant decrease in glutathione (GSH were observed in daphniid cells in lake Bia?e, while LPO levels were generally lower and GSH concentration more stable in the Sulejow reservoir. Catalase activity, which reflects more efficient oxidative protection, was always significantly higher in the reservoir than in lake Bia?e. These results demonstrate that generations of daphniids from the Sulejow reservoir had more effective antioxidant systems protecting them against the accumulation of cyanobacterial toxins; thereby, they are less susceptible to toxic effects than the daphniids from lake Bia?e. However, the presence of conjugate forms of microcystins (MC-GSH and MC-Cys in tissues of the studied animals indicated the ability for MC detoxification by daphniids from the Sulejow reservoir and lake Bia?e. Nevertheless, the high effectiveness of antioxidant systems in daphniids coexisting with cyanobacteria for a long time in the Sulejow reservoir indicates the importance of a selective pressure exerted by toxic cyanobacterial strains that favours the most resistant daphniid genotypes.

Benzylisoquinoline alkaloid metabolism: a century of discovery and a brave new world.  

Science.gov (United States)

Benzylisoquinoline alkaloids (BIAs) are a structurally diverse group of plant specialized metabolites with a long history of investigation. Although the ecophysiological functions of most BIAs are unknown, the medicinal properties of many compounds have been exploited for centuries. These include the narcotic analgesics codeine and morphine, the antimicrobial agents sanguinarine and berberine, and the antitussive and anticancer drug noscapine. BIA biosynthesis involves a restricted number of enzyme types that catalyze landmark coupling reactions and subsequent functional group modifications. A pathogenesis-related (PR)10/Bet v1 'Pictet-Spenglerase', several O-methyl-, N-methyl- and O-acetyltransferases, cytochromes P450, FAD-dependent oxidases, non-heme dioxygenases and NADPH-dependent reductases have been implicated in the multistep pathways leading to structurally diverse alkaloids. A small number of plant species, including opium poppy (Papaver somniferum) and other members of the Ranunculales, have emerged as model systems to study BIA metabolism. The expansion of resources to include a wider range of plant species is creating an opportunity to investigate previously uncharacterized BIA pathways. Contemporary knowledge of BIA metabolism reflects over a century of research coupled with the development of key innovations such as radioactive tracing, enzyme isolation and molecular cloning, and functional genomics approaches such as virus-induced gene silencing. Recently, the emergence of transcriptomics, proteomics and metabolomics has expedited the discovery of new BIA biosynthetic genes. The growing repository of BIA biosynthetic genes is providing the parts required to apply emerging synthetic biology platforms to the development of production systems in microbes as an alternative to plants as a commecial source of valuable BIAs.

Percent Body Fat Measured by Bioelectrical Impedance is not Associated with Colorectal Adenoma Status  

Directory of Open Access Journals (Sweden)

Full Text Available AIM: Obesity is a risk factor for colorectal neoplasia. Bioelectricalimpedance analysis (BIA is a novel and convenient method tomeasure body fat mass. The correlation between BIA and adenomarisk is unknown. We aimed to conduct a cross-sectional study toevaluate BIA and other measures of obesity as risk factors foradenomas.METHODS: Participants underwent screening colonoscopybetween 2006 and 2008. Waist-hip ratio (WHR and body massindex (BMI were measured. Percent body fat was calculated by BIAusing a proprietary scale. Physical activity and other risk factors wereassessed by telephone interview.RESULTS: 255 patients with adenomas and 679 non-adenomacontrols were included. Increased age, male sex, and decreasedphysical activity were associated with adenoma prevalence. Inmultivariate analysis, WHR and BMI were independently associatedwith adenoma prevalence. Patients in the highest tertile of WHR hadan OR of 2.0 (95% CI 1.2-3.2 compared to the lowest tertile. Obesewhite patients had significantly increased odds of having adenomas[OR 2.0 (95% CI 1.3, 3.2] compared to whites with a normal BMI.Percent body fat measured by BIA was not associated with adenomastatus: patients in the highest tertile of percent body fat had an OR of1.0 (95% CI 0.7-1.6 compared to patients with the lowest tertile.CONCLUSIONS: Percent body fat calculated by BIA was notassociated with adenoma prevalence. Although BIA is a quick andconvenient measure of adiposity, it is not predictive of adenomarisk perhaps because it measures the amount of fat but not thedistribution.

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

Science.gov (United States)

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

Validity of bioelectrical impedance analysis to estimate body composition changes after bariatric surgery in premenopausal morbidly women.  

Science.gov (United States)

In obese patients, subtle variations of the hydration of soft tissues can propagate errors in bioelectrical impedance analysis (BIA) measures of body composition. Bioelectrical impedance vector analysis (BIVA) is a useful method to evaluate tissue hydration. Laparoscopic adjustable gastric banding (LAGB) is a purely restrictive bariatric surgical procedure resulting in lower fat-free mass (FFM) loss than other malabsorptive or mixed intervention. The aim of this study was to evaluate the 6- and 12-month changes in body composition in a homogeneous group of premenopausal morbidly obese women treated by LAGB by comparing the results of conventional BIA and BIVA with dual-energy X-ray absorptiometry (DXA) method. Forty-five consecutive morbidly obese patients (mean age, 35.3 +/- 9.1 years; body mass index, 34.5-48.7 kg/m(2)) were prospectively evaluated at the Endocrinology Unit of the Department of Molecular and Clinical Endocrinology and Oncology. The LAGB device (Lap-Band System; Inamed Health, Santa Barbara, CA, USA) was inserted laparoscopically. Soft tissue hydration was evaluated by BIVA; fat mass (FM) and FFM were evaluated by BIA (BIA 101 RJL, Akern Bioresearch, Firenze, Italy) and by DXA (Hologic QDR 4500A S/N 45622; Hologic Inc., Bedford, MA, USA). Pre- and postoperative BIVA vectors indicated a normal hydration in all patients. Postoperatively, the excess of body weight loss was mainly due to a decrease in FM. The regression analysis of BIA and DXA methods at baseline and at the 6- and 12-month follow-up for FM r (2) values were 0.98, 0.94, and 0.99, respectively (p < 0.001); FM% r (2) values were 0.91, 0.89, and 0.98, respectively (p < 0.001); and FFM r (2) values were 0.87, 0.82, 0.99, respectively (p < 0.001). BIA and DXA measurements of body composition exhibit a high relative agreement in the study group of normo-hydrated obese subjects. BIA tends to overestimate FFM, but this effect is reduced along with the weight loss during the follow-up. Under the stable hydration, the BIA method may be useful as an alternative to DXA in a selected clinical setting when repeated comparisons of body composition are required. PMID:19862582

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese OBJETIVO: Verificar a concordância dos métodos de impedância bioelétrica (BIA) usando três equações diferentes, e medida das pregas cutâneas (PC) com absorciometria de raios-X de dupla energia (DEXA), para análise da composição corporal de mulheres com sobrepeso e obesidade. SUJEITOS E MÉTODOS: Em 3 [...] 4 mulheres (43,8 ± 10.9 anos; índice de massa corporal [IMC] 32,1 ± 4,3 kg/m²) foram avaliados: percentual de gordura total (%GT), massa gorda (MG) e massa magra (MM) por DEXA, PC, BIA-Fab (equação do fabricante), BIA-Segal e BIA-Gray (equações para obesidade). Foram utilizados: análise de regressão, método de Bland-Altman e coeficiente de correlação intraclasse (CCI). RESULTADOS: A concordância absoluta entre DEXA e BIA-Fab foi fraca para todas as medidas (BF% -6,8% ± 3,7%, FM -3,1 ± 3,6 kg, FFM 5,7 ± 2,8 kg). BIA-Segal apresentou boa concordância absoluta com DEXA para %GT (1,5% ± 1,5%), MG (1,0 ± 3,2 kg) e MM (1,5 ± 2,6 kg), mas com amplos limites de concordância. BIA-Gray teve boa concordância absoluta com DEXA para MG (2,3 ± 4,1 kg) e pequenos vieses para %GT (0,05% ± 4,4%) e MM (0,2 ± 2,9 kg), mas com amplos limites de concordância. BIA-Gray e DEXA tiveram maior CCI entre métodos. Houve boa concordância absoluta entre DEXA e PC para %GT (-2,3% ± 5,8%), MG (0,09 ± 4,7 kg) e MM (2,4 ± 4,4 kg), mas com amplos limites de concordância e pouca reprodutibilidade no CCI, entre DEXA e PC para %GT. CONCLUSÃO: A BIA, utilizando equação específica para obesidade, foi o método que melhor concordou com DEXA, para estimar %GT, MG e MM em mulheres com sobrepeso e obesidade. Abstract in english OBJECTIVE: The purpose of this study was to compare skinfold thickness (SKF) and bioelectrical impedance analysis (BIA) of body composition using three different equations against dual-energy X-ray absorptiometry (DXA) in overweight and obese Brazilian women. SUBJECTS AND METHOD: Thirty-four women ( [...] age 43.8 ± 10.9 years; body mass index [BMI] 32.1 ± 4.3 kg/m²) had percentage body fat (BF%), fat mass (FM) and fat-free mass (FFM) estimated by DXA, SKF and BIA (BIA-man: manufacturer's equation; and predictive obesity-specific equations of Segal and of Gray). Regression analysis, Bland-Altman plot analysis and intra-class correlation coefficient (ICC) were used to compare methods. RESULTS: Absolute agreement between DXA and BIA-man was poor for all measures of body composition (BF% -6.8% ± 3.7%, FM -3.1 ± 3.6 kg, FFM 5.7 ± 2.8 kg). BIA-Segal equation showed good absolute agreement with DXA for BF% (1.5% ± 1.5%), FM (1.0 ± 3.2 kg) and FFM (1.5 ± 2.6 kg), albeit the limits of agreement were wide. BIA-Gray equation showed good absolute agreement with DXA for FM (2.3 ± 4.1 kg), and smaller biases for BF% (0.05% ± 4.4%) and FFM (0.2 ± 2.9 kg), although wide limits of agreement. BIA-Gray and DXA showed the highest ICC among the pairs of methods. A good absolute agreement was observed between DXA and SKF for BF% (-2.3% ± 5.8%), FM (0.09 ± 4.7 kg), and FFM (2.4 ± 4.4 kg), although limits of agreement were wider and ICC between DXA and SKF for BF% indicated poor degree of reproducibility. CONCLUSION: These findings show that both BIA-Segal and BIA-Gray equations are suitable for BF%, FM and FFM estimations in overweight and obese women.

m-[125I]iodoaniline: a useful reagent for radiolabeling biotin  

International Nuclear Information System (INIS)

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.

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.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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.

Can abdominal bioelectrical impedance refine the determination of visceral fat from waist circumference?  

International Nuclear Information System (INIS)

Ryo et al (2005 Diabetes Care 28 451–3) reported a new method for measuring the visceral fat area (VFA) by combining abdominal bioelectrical impedance analysis (BIA) with measurement of waist circumference (WC), but very few methodological details were provided. Furthermore, the study did not test the use of WC alone as an indicator of VFA even though others had previously reported a strong correlation. We sought to determine the optimal measurement technique and analysis for measuring VFA by abdominal BIA and WC. 18 volunteers (age 23–64 years) underwent measurement of WC, abdominal impedance (Bodystat 500 four-electrode system) and a single cross-sectional CT scan at the umbilicus. VFA derived using WC3 and measurements of abdominal impedance from electrode pairs sited at the flank predicted the value of VFA measured by CT with correlation r = 0.904 (p 1.9 alone, without involving BIA at all, provided a similar correlation (r = 0.923). Our small preliminary study shows that abdominal BIA is potentially a practicable non-invasive technique for measurement of VFA but casts doubt on whether it adds any value to the use of WC alone. Larger studies are now required to test this finding. (note)

Noninvasive estimation of body composition in small mammals: a comparison of conductive and morphometric techniques.  

Science.gov (United States)

Body fat stores may serve as an index of condition in mammals. Thus, techniques that measure fat content accurately are important for assessing the ecological correlates of condition in mammal populations. We compared the ability of two conductive techniques, bioelectrical impedance analysis (BIA) and total body electrical conductivity (TOBEC), to predict body composition with that of morphometric methods in three small mammal species: red squirrels (n=13), snowshoe hares (n=30), and yellow-bellied marmots (n=4). Animals were livetrapped in northern Idaho; BIA (all subjects) and TOBEC (squirrels only) measurements were taken following chemical immobilization in the field, and morphometric measurements were taken postmortem. Information provided by BIA and TOBEC failed to improve upon the predictive power of morphometric equations for total body water (TBW) and lean body mass (LBM) in squirrels and hares, which do not store substantial amounts of fat (marmots, which accumulate substantial amounts of body fat (>10% body mass), a BIA-based model proved best at estimating TBW, suggesting that the usefulness of conductive techniques may be a function of fat deposition. However, regardless of the technique used to predict body composition, estimates of body fat furnished by our equations failed to approximate actual fat levels accurately in all three test species, probably because these techniques only provide indirect estimates of fat content. These results highlight the limitations inherent in contemporary methods of animal fat estimation and underscore the need for the development of direct and accurate measures of body fat in mammals.

Biosíntesis de alcaloides bencilisoquinolínicos  

Directory of Open Access Journals (Sweden)

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

Comparison of two methods of assessing total body water at sea level and increasing high altitude.  

Science.gov (United States)

Fluid retention is a recognized feature of acute mountain sickness. However, accurate assessment of hydration, including the quantification of body water, has traditionally relied on expensive and non-portable equipment limiting its utility in the field setting. We compared the assessment of total body water (TBW) and their relationship to total body weight using two non-invasive methods using the NICas single-frequency bioimpedance analysis (SF-BIA) system and the BodyStat QuadScan 4000 multifrequency BIA system (MF-BIA). TBW measurements were performed at rest at sea level and at high altitude (HA) at 3833 m postexercise and at rest and thereafter at rest at 4450 m and 5129 m on 47 subjects. The average age was 34·5 ± 9·3 years with an age range of 21-54 years (70·2% male). There were strong correlations between TBW assessment with both methods at sea level (r = 0·90; 95% CI 0·78-0·95: Pr = 0·92; 0·89-0·94: Pr = 0·91; Pr = 0·83; P<0·0001). The overall agreement between the two TBW methods was good, but the 95% confidence intervals around these agreements were relatively wide. We conclude that there was reasonable agreement between the two methods of BIA for TBW, but this agreement was lower at HA. PMID:24797153

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

Directory of Open Access Journals (Sweden)

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

Does impedance measure a functional state of the body fat?  

Science.gov (United States)

The aim was to compare methods of body fat measurement in different BMI groups. An additional aim was to discuss differences reflecting the structural and functional changes of fat tissue. The study group included 130 adult Caucasian women stratified by body mass index (BMI): 18-24.99 (n=30), 25-29.99 (n=26), 30-34.99 (n=33), 35-39.99 (n=30), and BMI>/=40 (n=11). Bioelectrical impedance was performed using Tanita TBF 410 GS, Bodystat 1500, and Omron BF 300. A caliper type Best was also applied. Correspondence of four methods with DEXA was assessed using the Bland-Altman and ANOVA analyses. Measurements by BIA were not significantly different from DEXA up to BMI of 30, but DEXA significantly overestimated in the higher BMI subgroup by all three methods. Caliper measurement significantly underestimated DEXA in all BMI subgroups. BIA methods overestimated DEXA for the obese subjects. Tanita did statistically the best. The Caliper test appeared less preferable than the BIA methods, especially in the higher BMI subgroup. DEXA and Caliper measurements seem to be the best estimate of structural (anatomical) fat quantity. We hypothesize that BIA methods could also measure some other physiopathological conditions like inflammation, hydration or cell infiltration of fat. PMID:24908237

Can abdominal bioelectrical impedance refine the determination of visceral fat from waist circumference?  

Science.gov (United States)

Ryo et al (2005 Diabetes Care 28 451-3) reported a new method for measuring the visceral fat area (VFA) by combining abdominal bioelectrical impedance analysis (BIA) with measurement of waist circumference (WC), but very few methodological details were provided. Furthermore, the study did not test the use of WC alone as an indicator of VFA even though others had previously reported a strong correlation. We sought to determine the optimal measurement technique and analysis for measuring VFA by abdominal BIA and WC. 18 volunteers (age 23-64 years) underwent measurement of WC, abdominal impedance (Bodystat 500 four-electrode system) and a single cross-sectional CT scan at the umbilicus. VFA derived using WC(3) and measurements of abdominal impedance from electrode pairs sited at the flank predicted the value of VFA measured by CT with correlation r = 0.904 (p < 0.0001); the optimizing power of WC was 3.3 (r = 0.905). However, the use of WC(1.9) alone, without involving BIA at all, provided a similar correlation (r = 0.923). Our small preliminary study shows that abdominal BIA is potentially a practicable non-invasive technique for measurement of VFA but casts doubt on whether it adds any value to the use of WC alone. Larger studies are now required to test this finding. PMID:19436083

The Influence of Segmental Impedance Analysis in Predicting Validity of Consumer Grade Bioelectrical Impedance Analysis Devices  

Science.gov (United States)

Consumer grade bioelectric impedance analysis (BIA) instruments measure the body's impedance at 50 kHz, and yield a quick estimate of percent body fat. The frequency dependence of the impedance gives more information about the current pathway and the response of different tissues. This study explores the impedance response of human tissue at a range of frequencies from 0.2 - 102 kHz using a four probe method and probe locations standard for segmental BIA research of the arm. The data at 50 kHz, for a 21 year old healthy Caucasian male (resistance of 180?±10 and reactance of 33?±2) is in agreement with previously reported values [1]. The frequency dependence is not consistent with simple circuit models commonly used in evaluating BIA data, and repeatability of measurements is problematic. This research will contribute to a better understanding of the inherent difficulties in estimating body fat using consumer grade BIA devices. [1] Chumlea, William C., Richard N. Baumgartner, and Alex F. Roche. ``Specific resistivity used to estimate fat-free mass from segmental body measures of bioelectrical impedance.'' Am J Clin Nutr 48 (1998): 7-15.

A rapid surface plasmon resonance (SPR) biosensor immunoassay for screening of somatotropins in injection preparations.  

Science.gov (United States)

The use of growth hormones (recombinant somatotropins (rSTs)) is approved in several countries, e.g. the USA, Brazil and Australia to enhance growth or lactating performances of livestock. Their use in the EU is banned, however, due to the widespread application, the illegal use within the EU cannot be excluded. To screen for rSTs in injection preparations, a biosensor immunoassay (BIA) using surface plasmon resonance (SPR) technology was developed. Compared to existing analysis methods for rSTs, like radio immunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA), this technique provides a rapid (7 min) alternative. A direct BIA was compared to an indirect (inhibition) BIA and the performances of several antibodies against (r)STs were compared in the indirect BIA. In the final inhibition assay, using rabbit anti-bovine rST, extracts from several injection preparations were shown to contain bovine rST (rbST). The limit of detection for rbST in the assay is 0.008 microg mL(-1) which is far below the expected concentrations in injection preparations. Although the cross-reactivities for STs of other species were low, screening of injection preparations for porcine, equine and human ST was feasible through the analysis of less diluted extracts. Tryptic digestion followed by nano-electrospray liquid chromatography-ion trap tandem mass spectrometry (nano-LC-MS/MS) was used to identify STs. PMID:17386718

Effect of environmental factors on the biosynthesis of the neuro-excitatory amino acid ?-ODAP (?-N-oxalyl-L-?,?-diaminopropionic acid) in callus tissue of Lathyrus sativus.  

Science.gov (United States)

Habituated callus tissues derived from leaf explants of Lathyrus sativus L. (grass pea) were cultured under different environmental conditions such as drought, salinity and deficiency or oversupply of micronutrients. The biosynthesis of the neuro-excitatory ?-ODAP (?-N-oxalyl-L-?,?-diaminopropionic acid) was induced by feeding the precursor BIA, (?-isoxazolin-5-on-2-yl)-alanine, to those calli habituated under different stress conditions. Conversion of BIA into ?-ODAP was reduced by Zn(2+) at different levels of Fe(2+) supplements while excess of Fe(2+) enhanced it at different Zn(2+) levels in the media. The biosynthesis of ?-ODAP was increased by both oversupply and deficiency of Mn(2+) manganese while B(3+) as well as Co(2+) increased it significantly by oversupply. Al(3+) enhanced the conversion of BIA into ?-ODAP significantly in a concentration-dependent way. Cu(2+) also reduced the formation of ?-ODAP when increased in the media. Mo(6+) had no apparent effect. NaCl decreased the conversion of BIA into ?-ODAP proportionately with the increase in salinity. ?-ODAP was increased with increasing mannitol concentration till -0.23MPa while at this osmotic potential created with PEG-20,000 the formation of ?-ODAP is completely inhibited in low toxin calli. These experiments demonstrate the importance of environmental factors, especially micronutrients and salinity, on the biosynthesis of ?-ODAP. PMID:20654675

Estimation of thigh muscle cross-sectional area by single- and multifrequency segmental bioelectrical impedance analysis in the elderly.  

Science.gov (United States)

Bioelectrical impedance analysis (BIA) has been used to estimate skeletal muscle mass, but its application in the elderly is not optimal. The accuracy of BIA may be influenced by the expansion of extracellular water (ECW) relative to muscle mass with aging. Multifrequency BIA (MFBIA) can evaluate the distribution between ECW and intracellular water (ICW), and thus may be superior to single-frequency BIA (SFBIA) to estimate muscle mass in the elderly. A total of 58 elderly participants aged 65-85 years were recruited. Muscle cross-sectional area (CSA) was obtained from computed tomography scans at the mid-thigh. Segmental SFBIA and MFBIA were measured for the upper legs. An index of the ratio of ECW and ICW was calculated using MFBIA. The correlation between muscle CSA and SFBIA was moderate (r = 0.68), but strong between muscle CSA and MFBIA (r = 0.85). ECW/ICW index was significantly and positively correlated with age (P ECW in the thigh segment (P ECW was observed in older participants. The relative expansion of ECW affects the validity of traditional SFBIA, which is lowered when estimating muscle CSA in the elderly. By contrast, MFBIA was not affected by water distribution in thigh segments, thus rendering the validity of MFBIA for estimating thigh muscle CSA higher than SFBIA in the elderly. PMID:24114698

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

Energy Technology Data Exchange (ETDEWEB)

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

Polycyclic aromatic hydrocarbons in the airborne particulate matter at a location 40 km north of Bangkok, Thailand  

Science.gov (United States)

Total suspended particulate matter in ambient air was sampled by high-volume samplers at four sites at the Asian Institute of Technology campus, west of the Phahonyothin Road, Phathumthani Province, 40 km North of Bangkok, Thailand. The concentrations of 18 polycyclic aromatic hydrocarbons (PAH), were measured by gas chromatography with flame ionisation and/or liquid chromatography with fluorescence detection. The PAH profile with relatively high concentrations of benzo(ghi)perylene and coronene, decreasing with the distance from the road, suggested a substantial contribution from the traffic. The concentrations in the core of the campus were in the same range as those reported for residential areas in the Bangkok Metropolitan.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Gasto energético de adultos brasileños saludables: una comparación de métodos Energy expenditure of healthy brazilian adults: a comparison of methods  

Directory of Open Access Journals (Sweden)

Full Text Available Hay diversos métodos disponibles para medir el consumo de energía en el ser humano. Debido al alto costo y pequeño número de laboratorios capaces de utilizar la calorimetría directa y la técnica del agua doblemente marcada, se ha realizado un número relativamente pequeño de mediciones del gasto energético utilizándose estos métodos. Así, cada día más, los investigadores se atienen en alto grado a los métodos de calorimetría indirecta (CI y bioimpedancia eléctrica (BIA y los clínicos a las ecuaciones de predicción para calcular los requerimientos de energía total en sus estudios y pacientes respectivamente. Objetivo: Evaluar el Gasto Energético Basal (GEB y el Gasto Energético Total (GET de individuos saludables comparando los resultados de CI, BIA y ecuaciones predictivas con los de requerimiento estimado de energía (EER, Fleisch, FAO/WHO/UNU 1985 y 2001. Material y métodos: Se evaluó el gasto energético en 81 individuos de ambos sexos por CI y BIA. De estos, fueron calculados el GEB por las ecuaciones FAO/WHO/UNU 1985 y 2001 y el GET por EER, Fleisch y FAO/WHO/UNU 1985 y 2001. Los datos se analizaron con el programa Sigma Stat for Windows versión 2.03 y se utilizó eltest de Dunn's para la comparación de las medianas obtenidas por los métodos y ecuaciones (p There are many available methods to measure the human energy consumption. Due to the high cost and small number of laboratories able to perform it, the direct calorimetry and doubly labeled water technique are rarely used to measure the energy expenditure. As consequence, there is an increase use of the indirect calorimetry and bioelectrical impedance analysis methods by researchers and predictive equations by physicians to calculate the total energy requirements in research and in clinic. Objective: To evaluate the basal energy expenditure (GEB and total energy expenditure (GET of healthy subjects comparing results of indirect calorimetry (CI, bioelectrical impedance analysis (BIA and predictive equations such as estimated energy requirements (EER, Fleish, FAO/WHO/UNU 1985 and 2001. Material and methods: It was evaluated the energy expenditure in 81 subjects of both gender by CI and BIA. Of these, the GEB by predictive equations FAO/WHO/UNU 1985 and 2001 and the GET by EER, Fleisch and FAO/WHO/UNU 1985 and 2001 were calculated. The data was analyzed with the software Sigma Stat for Windows version 2.03 and Dunn's test was used for comparison of mean obtained with methods and equations (p < 0.05. Results: It was verified that 60.5% of the participants were men. The majority of subjects were eutrofic. BIA showed significant differences between men and women. The differences between the values of GEB, obtained by BIA and CI, were statistically significant only for women (p < 0.05 with an underestimation of the GEB results obtained by BIA in relation to those obtained by CI. Significant difference was found between the predictive equations and CI for both sexes, also demonstrating an underestimation of the equations in relation to CI. It was observed an overestimation of GET with the predictive equations of FAO/WHO/UNU/85 and 2001 in relation to EER and Fleisch for both sexes. Conclusion: The estimation of GEB can be carried out by both BIA and CI, although BIA must be used with criteria since it underestimates in a significant way for women. In relation to the predictive equations, overestimation can develop positive energy balance in populations with risks for overweight and obesity. Thus, it is necessary comparisons to identify the limitations of each method.

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)

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 impedance (R) was also insignificant. Three BIA equations from the literature, which were not specific for the degree of obesity in the present study group, predicted changes in FFM (from 0.5 + 3.6 to 2.4 +/- 4.4kg, p > 0.05) that were comparable with those estimated by the reference methods. Eight equations from the literature, which included equations specific for the degree of obesity in the study group, and the group specific equations developed for the present population predicted significant changes in FFM during weight loss (from 2.3 +/- 3.0 to 5.0 +/- 3.0 kg, p < 0.05). We conclude that in obesity most predictive equations are unable to predict static body composition and are not reproducible for individuals over time. However, a significant or insignificant change in R (without accompanying predictive equations) may be used to indicate whether FFM is lost or preserved in groups of obese subjects.

Source Assessment and Analysis of Polycyclic Aromatic Hydrocarbon (PAH’s in the Oblogo Waste Disposal Sites and Some Water Bodies in and around the Accra Metropolis of Ghana  

Directory of Open Access Journals (Sweden)

Full Text Available The study looked at the levels of polycyclic aromatic hydrocarbons (PAHs in leachates from a solid waste disposal site and an effluent from an oil refinery in some water bodies around Accra. Sixteen (PAHs were extracted simultaneously by solid phase and analysis by gas chromatograph. The results of this study gener-ally demonstrated that there were elevated levels of PAHs in the water sample of the Densu River, Chemu, Korle and Kpeshi Lagoons. The average concentration of PAHs in the water ranged from 0.000 of many of the PAHs to 0.552µg/L, for Acenapththene to 11.399µg/L for Benzo (ghi perylene of the Chemu Lagoon, 0.00µg/L for Benzo (a Pyrene to 8.800µg/L for Benzo (ghi perylene (Korle Lagoon and 0.052µg/L for Pyrene to 4.703ug/L for Acenaphthylene of the Kpeshi Lagoon and 0.00µg/L for pyrene to Acenaphthylene 2.926µg/L of the Weija Dam. Concentrations ranging from below detection level to 14.587µg/L were also recorded at the Oblogo solid waste dump and it’s environ. The Weija dam supply over two million gallons of portable water daily to the people of Accra and the levels of the PAH determined is worrying, as a result, the Oblogoh disposal site ought to be re-located to avert any possible epidemic.

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.

Global horizontal irradiance clear sky models : implementation and analysis.  

Energy Technology Data Exchange (ETDEWEB)

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

A wintertime study of PAHs in fine and coarse aerosols in São Paulo city, Brazil  

Science.gov (United States)

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.

A Guidebook to Help Coastal Sumatran Communities Prepare for Tsunamis  

Science.gov (United States)

One way to save lives in future tsunamis in coastal Sumatran communities - where more than one million people live and where tsunamis can strike less than one half hour after the triggering earthquake - is to help these communities prepare themselves. To this end, GeoHazards International (GHI) has developed, with a team of advisors from the fields of earth science, civil engineering, emergency response management and social science, a tsunami preparedness guidebook that summarizes state-of-the-art research and worldwide experience in community tsunami preparedness. This guidebook (available at no cost on www.geohaz.org) introduces essential information about tsunamis, tsunami risk mapping, evacuation planning, community education, tsunami warning systems, and the reduction of damage that tsunamis can cause. It describes how to plan and conduct effective tsunami safety programs. Particular emphasis is placed on methods to evacuate quickly and safely all areas that could be flooded. Each section of the guidebook points to sources that provide supplementary, detailed information that may be important to particular communities. The guidebook is aimed at any person - a concerned citizen, government official, business leader, or member of a community organization - who is willing to become an advocate for local tsunami safety. Scientific expertise is not needed. GHI now seeks assistance in distributing this guidebook and in working with grassroots and international organizations to help Sumatran coastal communities use it to prepare for the next tsunami.

Polycyclic aromatic hydrocarbon removal from soil by surfactant solubilization and Phanerochaete chrysosporium oxidation.  

Science.gov (United States)

Surfactant soil washing can remove polycyclic aromatic hydrocarbons (PAHs) from contaminated soil, and the white rot fungus, Phanerochaete chrysosporium Burdsall in Burdsall & Eslyn, can oxidize PAHs. The objective of this study was to develop a novel bioremediation technology using a combination of abiological surfactant soil washing followed by PAH biological oxidation in soil washwater using P. chrysosporium in a rotating biological contactor (RBC) reactor. Soil used for experimentation was an 11-month aged contaminated soil spiked with a total of nine PAHs: acenaphthene, fluorene, phenanthrene, fluoranthene, pyrene, chrysene, benzo(a)pyrene, dibenz(a-h)anthracene, and benzo(ghi)perylene. After 11 months of aging, recovery percentages of high molecular weight PAHs [i.e., from chrysene to benzo(ghi)perylene] were greater than 86%, while those of low molecular weight PAHs (i.e., from acenaphthene to pyrene) were less than 19%. Total removal efficiency for any of the nine PAHs was greater than 90% using a combination of surfactant soil washing and P. chrysosporium oxidation of soil washwater in the RBC reactor when used in batch operation, and greater than 76% when used in continuous operation. The treatment of PAH-contaminated soil using a combination of surfactant soil washing and subsequent PAH removal from the resultant washwater in an RBC reactor, in the presence of immobilized P. chrysosporium, permits (i) a rapid abiological cleanup of soil for compliance with relevant soil quality standards and (ii) PAH biological removal in soil washwater for compliance with aqueous discharge standards.

Genetic variation of dry matter and nitrogen accumulation of double haploid wheat lines  

International Nuclear Information System (INIS)

The study considers the genotype peculiarities in the dynamics of dry matter and nitrogen accumulation in plant parts during the different stages of 10 DH wheat lines characterized as initial breeding material of high quality. These were obtained from 2 crosses - 7-P2 - 11 x H-81/32-4 and 7-P2 - 11 x H-81/32-24. Considerable genotype variations were established both between the lines and the parental forms, and in comparison to the standard quality variety Slavyanka-196. Lines 41-191 and 41-344 are of special interest because of their high grain yield and high intensity of biomass accumulation (kg/dka/day) and high intensity of nitrogen uptake (g/dka/day) mainly in the second half of the grain filling period. These fines stand out among the new DH fines with their high protein yields. In line 41-181 the ratio NHI/GHI changes positively with a high degree of certainty in both phases of grain maturity. This line is characterized with the highest value of nitrogen (mg) in vegetation mass per unit mature grain. A positive correlation was established between the NHI/GHI ratio and protein content in grain. Line 41-344 is the most economic one with regard to nitrogen formation per 100 kg grain with the lowest expense for formation of the respective quantity of straw. Refs. 5 (author)

Laboratory systems and services are critical in global health: time to end the neglect?  

Science.gov (United States)

The $63 billion comprehensive global health initiative (GHI) emphasizes health systems strengthening (HSS) to tackle challenges, including child and maternal health, HIV/AIDS, family planning, and neglected tropical diseases. GHI and other initiatives are critical to fighting emerging and reemerging diseases in resource-poor countries. HSS is also an increasing focus of the $49 billion program of the US President's Emergency Plan for AIDS Relief and the Global Fund to Fight AIDS, Tuberculosis and Malaria. Laboratory systems and services are often neglected in resource-poor settings, but the funding offers an opportunity to end the neglect. To sustainably strengthen national laboratory systems in resource-poor countries, the following approaches are needed: (1) developing integrative national laboratory strategic plans and policies and building systems to address multiple diseases; (2) establishing public-private partnerships; (3) ensuring effective leadership, commitment, and coordination by host governments of efforts of donors and partners; (4) establishing and/or strengthening centers of excellence and field epidemiology and laboratory training programs to meet short- and medium-term training and retention goals; and (5) establishing affordable, scalable, and effective laboratory accreditation schemes to ensure quality of laboratory tests and bridge the gap between clinicians and laboratory experts on the use of test results.

Bioelectrical impedance among rural Bangladeshi Women during pregnancy and in the postpartum period.  

Science.gov (United States)

Properties of bioelectrical impedance analysis (BIA) reflect body-composition and may serve as stand-alone indicators of maternal health. Despite these potential roles, BIA properties during pregnancy and lactation in rural South Asian women have not been described previously, although pregnancy and infant health outcomes are often compromised. This paper reports the BIA properties among a large sample of pregnant and postpartum women of rural Bangladesh, aged 12-46 years, participating in a substudy of a community-based, placebo-controlled trial of vitamin A or beta-carotene supplementation. Anthropometry and single frequency (50 kHz) BIA were assessed in 1,435 women during the first trimester (women during the third trimester (32-36 weeks gestation), and in 1,141 women at 12-18 weeks postpartum. Resistance and reactance were recorded, and impedance and phase angle were calculated. Data were examined cross-sectionally to maximize sample-size at each timepoint, and the factors relating to BIA properties were explored. Women were typically young, primiparous and lacking formal education (22.2 +/- 6.3 years old, 42.2% primiparous, and 39.7% unschooled among the first trimester participants). Weight (kg), resistance (omega), and reactance (omega) were 42.1 +/- 5.7, 688 +/- 77, and 73 +/- 12 in the first trimester; 47.7 +/- 5.9, 646 +/- 77, and 64 +/- 12 in the third trimester; and 42.7 +/- 5.6, 699 +/- 79, and 72 +/- 12 postpartum respectively. Resistance declined with age and increased with body mass index. Resistance was higher than that observed in other, non-Asian pregnant populations, likely reflecting considerably smaller body-volume among Bangladeshi women. Resistance and reactance decreased in advanced stage of pregnancy as the rate of gain in weight increased, returning to the first trimester values by the three months postpartum. Normative distributions of BIA properties are presented for rural Bangladeshi women across a reproductive cycle that may be related to pregnancy outcomes and ultimately be used for assessing body-composition in this population.

Phase angle and bioelectrical impedance vectors in adolescent and adult male athletes.  

Science.gov (United States)

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

Cryogenic optical position encoders for mechanisms in the JWST optical telescope element simulator (OSIM)  

Science.gov (United States)

The JWST Optical Telescope Element Simulator (OSIM) is a configurable, cryogenic, optical stimulus for high fidelity ground characterization and calibration of JWST's flight instruments. OSIM and its associated Beam Image Analyzer (BIA) contain several ultra-precise, cryogenic mechanisms that enable OSIM to project point sources into the instruments according to the same optical prescription as the flight telescope will image stars - correct in focal surface position and chief ray angle. OSIM's and BIA's fifteen axes of mechanisms navigate according to redundant, cryogenic, absolute, optical encoders - 32 in all operating at or below 100 K. OSIM's encoder subsystem, the engineering challenges met in its development, and the encoders' sub-micron and sub-arcsecond performance are discussed.

Batch-injection stripping voltammetry (tube-less flow-injection analysis) of trace metals with on-line sample pretreatment.  

Science.gov (United States)

The most essential limitation of batch-injection analysis (BIA) methodology compared to other flow methods (CFA, FIA, SIA) is the lack of possibility of on-line sample processing in the measuring system. Some procedures of on-line sample pretreatment in BIA are possible by changing the plastic tip of the automatic micropipette used for sample injection into a flow-through reactor, e.g. by packing it with a bed of a solid sorbent. This concept is employed in the voltammetric stripping determinations of trace metals using a bed of commercial chelating resin Chelex-100. It was found that, besides the electrochemical preconcentration of analytes in the form of amalgams on the surface of mercury thin film electrodes, an approximately 10-fold additional preconcentration can be achieved on the packed sorbent bed by using different volumes of aspirated sample solution and eluent. This procedure allows also efficient elimination of some matrix effects. PMID:18970335

(R,S)-Tetrahydropapaveroline production by stepwise fermentation using engineered Escherichia coli  

Science.gov (United States)

Tetrahydropapaveroline (THP), a benzylisoquinoline alkaloid (BIA) found in diverse pharmaceutical compounds, is used as a starting material for the production of BIA. THP also has various neurobiological properties but is difficult to synthesize. Therefore, a simple method for THP production is desired. Recent studies have shown that microbes, especially bacteria, can serve as platforms for synthesizing these complex compounds; however, because bacteria lack organelles, the designed synthetic pathway cannot be compartmentalized. Thus, the metabolic flow is frequently inhibited or disrupted by undesirable reactions. Indeed, in the first attempt to synthesize THP using a single strain of engineered Escherichia coli, the yield was quite low (fermentation is useful for the production of reticuline, an important BIAs intermediate. Based on these observations, applying the stepwise fermentation method is discussed. PMID:25331563

Pharmaceutical applications of the benzylisoquinoline alkaloids from Argemone mexicana L.  

Science.gov (United States)

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

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.

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.

The application of bioelectrical impedance analysis in live tropical hair sheep as a predictor of body composition upon slaughter.  

Science.gov (United States)

Animal management for breeding and marketing can be improved by precise measurement of desirable traits. Live animal body composition analysis facilitates the selection of animals that are best suited for the intended purpose. This study was designed to assess the accuracy of bioelectrical impedance analysis (BIA) predicted live body tissue composition, as a proxy for the estimation of carcass quality in Barbados Black Belly lambs. Thirty-four Barbados Black Belly lambs were placed on an 8-week feeding regime and then slaughtered. A randomized experimental design was used to allocate diets to animals, which had been stratified into eight groups by initial live weight. The lambs were fed a basal diet of Brachiaria arrecta fresh forage ad libitum and subjected to one of four diets; NS-non-supplemented diet, TG-Trichantera gigantea-supplemented, C100-concentrate supplemented for maintenance, and C400-concentrate supplemented for growth. Diets NS, TG, C100, and C400 had 7, 9, 11, and 7 animals, respectively. The average age and weight at the time of slaughter were 206 days and 23.7 kg, respectively. A 4-terminal impedance analyzer (RJL Systems®) was used to generate BIA data from live animals immediately before slaughter. The chilled carcasses were then subject to chemical analysis for crude fat, crude protein, and dry matter. Live animal and carcass traits predicted by BIA included fat and fat-free mass, crude fat, crude protein, protein to fat ratio, and tissue distribution. Regression equations were developed from BIA data obtained from the live animal to predict all carcass composition traits measured. Bioelectrical impedance analysis generated favorable results as a practical application to carcass composition evaluation in live tropical hair sheep. PMID:23852279

DXA, bioelectrical impedance, ultrasonography and biometry for the estimation of fat and lean mass in cats during weight loss  

Directory of Open Access Journals (Sweden)

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.
