The aim of the present study was to determine the relationship among body weight (BW), body condition score (BCS) and rump fat thickness (RFAT) measured by ultrasonography, and validate the relationship between BCS and RFAT over the time. Two hundred sixty and six Nelore cows had their BW, BCS and RFAT evaluated at five different moments during the production cycle: M1) weaning: M2) parturition, M3) 42 days post-partum; M4) 82 days postpartum and M5) 112 days post-partum. A BCS value was attributed for each cow following a I to 5 points scale. Ultrasonographic images for RFAT measurement were obtained using a 3.5 MHz linear transducer. Images were immediately analyzed as soon as they were formed and frozen. Body condition scores and ultrasound measurements were collected on the same day by a single trained technician. The relationship between BCS and RFAT values was investigated by regression models. The analysis of similarity among the five obtained models was performed using the proc MIXED from SAS and the correlations among variables were analyzed with proc CORR from SAS. The BCS was able to predict RFAT in Nelore cows in all different moments evaluated. Also, it was shown that BCS presented high correlation (r=0.82 to 0.93) and relationship (R(2) = 0.73 to 0.92) with RFAT. However...

This study aims to evaluate the thickness of the femoral quadriceps and biceps brachii and brachialis muscles bilaterally and the adjacent subcutaneous fat in patients undergoing gastric bypass Roux-en-Y before and after surgery, using ultrasound as the diagnostic method of choice. We studied 12 patients undergoing this surgical method preoperatively and during the first, third, and sixth postoperative months. During these periods, patients were evaluated by ultrasound to determine the thickness of subcutaneous adipose tissue and muscle of the upper and lower limbs. Postoperatively, these patients showed a reduction in the thickness of the upper and lower extremities muscle and adipose tissue as compared to their preoperative values. There was a significant difference in the loss of muscle thickness in all postoperative months and in the thickness of fatty tissue in the sixth month after surgery, compared to the preoperative muscle and fatty tissue thickness. Ultrasound can be considered as the diagnostic method of choice when assessment of the fat and lean body mass is required in morbidly obese patients before and after bariatric surgery.

Introdução: O aumento alarmante da obesidade em todo mundo é um fator independente para o aumento da prevalência de doenças crônicas, como diabetes, hipertensão arterial e doença hepática gordurosa não alcoólica (DHGNA). A DHGNA engloba um amplo espectro de doença desde esteatose simples sem sinais inflamatórios, evoluindo para esteatohepatite (ENA) e até cirrose. Por ser uma patologia multifatorial sua patogênese e terapêutica ainda apresentam pontos obscuros. A resistência à insulina é um dos fatores que já foram determinados como importantes na fisiopatogênese da DHGNA e, está diretamente relacionado ao estilo de vida e hábitos alimentares. Objetivo: Avaliar a correlação entre a presença da gordura visceral e subcutânea à resistência insulínica, síndrome metabólica, medidas antropométricas e hábitos alimentares em pacientes portadores DHGNA. Resultados: Sessenta por cento dos pacientes com DHGNA apresentavam Síndrome Plurimetabólica de acordo com os critérios do ATP III. Dentre os critérios mais prevalentes da síndrome metabólica, níveis baixos HDL e circunferência de cintura (CC) aumentada ocorreram em 56%. Ao dividirmos os pacientes em grupos, os critérios se modificaram. Nos pacientes portadores de esteatose simples...

In Northeast Portugal donkeys usually face seasonal food shortage and often their basic requirements are not properly met. Body condition score (BCS) may be used to assess a donkey’s welfare and nutritional status, but the procedure is highly subjective. For several domestic species the relationships between the ultrasound subcutaneous fat depth, the body condition score and the body subcutaneous fat distribution have already been establish. Interspecies differences on the most relevant site for ultrasound collection of data have been demonstrated, in particular between equids and ruminants, which are related with anatomic features. In donkeys no available information exists on the relationship between ultrasonographic fat amount and its pattern of deposition and the BCS, and a preliminary study was developed using 16 adult jennets of the Asinina de Miranda breed, in a total of 33 examinations for BCS and real time ultrasound (RTU). RTU images were acquired to determine the subcutaneous fat depth (SF), measured at the neck; loin; rump and tail-head, and tissue depth (TD) measured at ribs. SF distribution was analysed and the correlations between BCS and RTU measurements were assessed. The largest variations in SF deposition were found along the thoracolumbar axis...

OBJECTIVE: To verify the influence of visceral and subcutaneous fat, as well adipokines in bone mineral density (BMD) in obese adolescents. SUBJECTS AND METHODS: The study involved 125 postpubertal obese adolescents (45 boys and 80 girls). Anthropometric measurements, body composition, visceral and subcutaneous fat, and BMD were determined. Leptin, adiponectin, and insulin levels also analyzed. RESULTS: Data demonstrated a negative relationship between BMD with insulin resistance, visceral fat and leptin concentration; and bone mineral content with visceral/subcutaneous ratio. Positive association between BMD and subcutaneous fat was observed. CONCLUSIONS: Visceral fat and insulin resistance, as well as visceral/subcutaneous ratio and leptin concentration, were negative predictors of BMD in boys and girls, respectively. However, subcutaneous fat had a protective influence in BMD only in boys.

Context The mesenteric fat is drained by the portal system, being related to the metabolic syndrome which is an impor­tant risk factor for non-alcoholic fatty liver disease (NAFLD). Objectives Graduate of visceral fat thickness and correlate with the NAFLD degree through ultrasonography method. Methods We studied 352 subjects for age, gender, measures of subcutaneous fat thickness and visceral fat thickness as well as the presence and degree of liver fatty. Was analyzed the independent relationship between visceral fat thickness and NAFLD, and linear regression analysis was used in order to predict the visceral fat thickness from subcutaneous fat thickness. Results The mean age of 225 women (63.9%) and 127 men (36.1%) was 47.5 ± 14.0 (18-77) years, 255 subjects had normal examinations, 97 had NAFLD thus distributed, 37 grade 1, 32 grade 2, and 28 grade 3. The subcutaneous fat thickness ranged from 0.26 to 3.50 cm with a mean of 1.3 ± 0.6 cm and visceral fat thickness ranged from 0.83 to 8.86 cm with a mean of 3.6 ± 1.7 cm. Linear regression showed that for every increase of 1 cm in subcutaneous fat thickness the visceral fat thickness will increase 0.9 cm. Conclusions The visceral fat thickness measured by ultrasonography is a useful and seems to be able to help estimate the risk of NAFLD.

Subcutaneous fat necrosis of the newborn is an unusual form of panniculitis, with few cases described in medical literature. The disease affects newborns at term or post-term, with normal general health. We describe two cases of newborns affected by the disease. One of them already had lesions since birth. Also, we discuss the use of puncture for diagnostic assistance.

Women entering pregnancy with a high body weight and fat mass have babies who are at increased risk of becoming overweight or obese in later life. We investigated whether maternal overnutrition in the periconceptional period results in an increased fat mass and expression of adipogenic and lipogenic genes in offspring and whether dietary restriction can reverse these changes. Nonpregnant donor ewes (n = 23) were assigned to one of four groups: control-control fed at 100% maintenance energy requirements (MER) for at least 5 months, control-restricted fed 100% MER for 4 months and 70% MER for 1 month, high-high (HH) fed ad libitum (170–190% MER) for 5 months, or high-restricted (HR) fed ad libitum for 4 months and 70% MER for 1 month. Single embryos were transferred to nonobese recipient ewes, and lamb fat depots were weighed at 4 months. Peroxisome proliferator-activated receptor-{gamma}, glyceraldehyde-3-phosphate dehydrogenase, lipoprotein lipase, leptin, and adiponectin mRNA expression was measured in the lamb fat depots. Total fat mass was higher in female lambs in the HH but not HR group than controls. There was a relationship between donor ewe weight and total fat mass and G3PDH mRNA expression in perirenal fat in female lambs. There was no effect of periconceptional nutritional treatment on peroxisome proliferator-activated receptor-{gamma}...

Body fat distribution, particularly centralized obesity, is associated with metabolic risk above and beyond total adiposity. We performed genome-wide association of abdominal adipose depots quantified using computed tomography (CT) to uncover novel loci for body fat distribution among participants of European ancestry. Subcutaneous and visceral fat were quantified in 5,560 women and 4,997 men from 4 population-based studies. Genome-wide genotyping was performed using standard arrays and imputed to ~2.5 million Hapmap SNPs. Each study performed a genome-wide association analysis of subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), VAT adjusted for body mass index, and VAT/SAT ratio (a metric of the propensity to store fat viscerally as compared to subcutaneously) in the overall sample and in women and men separately. A weighted z-score meta-analysis was conducted. For the VAT/SAT ratio, our most significant p-value was rs11118316 at LYPLAL1 gene (p = 3.1×10E-09), previously identified in association with waist–hip ratio. For SAT, the most significant SNP was in the FTO gene (p = 5.9×10E-08). Given the known gender differences in body fat distribution, we performed sex-specific analyses. Our most significant finding was for VAT in women...

The amount and distribution of adipose tissue is important to cattle production. Fat influences the animal’s reproductive efficiency and determines its carcass value. As a cow’s reproductive efficiency is associated with a level of overall fatness, not just a particular fat depot, being able to re-partition fat to a more valuable depot while reducing fat in less valuable depots would be advantageous. Most previous research involving fat deposition in cattle focussed on subcutaneous and intramuscular fat, and usually evaluated these in relation to total fat or carcass weight rather than the relationship between individual fat depots. The hypothesis that there is a genetic basis for variation in fat distribution in cattle and a weak relationship between fat depots independent of anatomical site was tested. The principal aim of this research was to gain a better understanding of the mechanisms controlling fat deposition in cattle, including any relationship between fat depots. Marbling features (e.g. shape and orientation) and seam (intermuscular) fat area were quantified using image analysis. The seam fat area and other carcass fat measurements were used to examine the relationship between fat depots. Candidate genes for fat deposition traits were identified and sequenced in Jersey – Limousin mapping sires to find single nucleotide polymorphisms (SNPs). In all...

beta, beta-carotene-9', 10'-dioxygenase (BCO2) plays a role in cleaving beta-carotene eccentrically, and may be involved in the control of adipose and milk colour in cattle. The bovine BCO2 gene was sequenced as a potential candidate gene for a beef fat colour QTL on chromosome (BTA) 15. A single nucleotide base change located in exon 3 causes the substitution of a stop codon (encoded by the A allele) for tryptophan(80) (encoded by the G allele) (c. 240G>A, p.Trp80stop, referred to herein as SNP W80X). Association analysis showed significant differences in subcutaneous fat colour and beta-carotene concentration amongst cattle with different BCO2 genotypes. Animals with the BCO2 AA genotype had more yellow beef fat and a higher beta-carotene concentration in adipose tissues than those with the GA or GG genotype. QTL mapping analysis with the BCO2 SNP W80X fitted as a fixed effect confirmed that this SNP is likely to represent the quantitative trait nucleotide (QTN) for the fat colour-related traits on BTA 15. Moreover, animals with the AA genotype had yellower milk colour and a higher concentration of beta-carotene in the milk.; R. Tian, W. S. Pitchford, C. A. Morris, N. G. Cullen and C. D. K. Bottema

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 < 0.005) with the dependent variables (FM and LM) were BW (body weight), TC (thoracic circumference), PC (pelvic circumference), R (resistance) and SFLT (subcutaneous fat layer thickness).

Introduction: Thermography records the skin temperature, which can be influenced by: muscle mass and subcutaneous fat layer. Thus, the aim of this study was to investigate the influence of subcutaneous fat layer in the skin temperature variation rate, during exercise. Methods This is a short-longitudinal study that involved 17 healthy male trained volunteers. Volunteers were divided in two groups. The first called GP1 with nine volunteers (biceps brachii skinfold thickness < 4 mm) and the second called GP2 with eight volunteers (biceps brachii skinfold thickness from 4 to 8 mm). Both groups performed three sets with 16 repetitions of unilateral biceps brachii bi-set exercise with dominant arm (eight repetitions of biceps curls and another eight of biceps hammer curls, with dumbbells), and with load of 70% of 1RM. The rest time between sets was 90s. Results The skin temperature variation rate (variation of temperature / time) was 3.59 × 10-3 ± 1.47 × 10-3 °C/s for GP1 and 0.66 × 10-3 ± 4.83 × 10-3 °C/s for GP2 (p = 0.138) considering all moments. For the period after set 1 until the end of set 3, skin temperature variation rate was 5.11 × 10-3 ± 2.57 × 10-3 °C/s for GP1 and 1.88 × 10-3 ± 3.60 × 10-3 °C/s for GP2 (p = 0.048). Subcutaneous fat layer also influences the skin temperature at resting (p = 0.044). Conclusion Subjects with lower subcutaneous fat layer have a higher skin temperature variation rate during exercise than those with higher subcutaneous fat layer.

12 pages, 6 figures.-- PMID: 19203289 [PubMed].-- Article in press.; Obesity is increasing exponentially in developed countries and constitutes a public health problem by enhancing the risk for metabolic disorder and cardiovascular disease. Differences in gene expression profiles and in metabolic and biochemical properties have been well-described between omental and subcutaneous adipose tissue in humans. Because omental adipose tissue has been strongly associated with the development of insulin resistance, type 2 diabetes and cardiovascular disease, we searched for proteins differentially expressed in these two fat depots using two-dimensional fluorescence difference gel electrophoresis (2D-DIGE) and mass spectrometry (MS). In this analysis, we found 43 proteins, several of which were validated by immunoblotting and immunostaining analyses. Results demonstrated tissue-specific molecular differences in the protein makeup of the two analyzed fat depots mainly related to metabolic processes such as glucose and lipid metabolism, lipid transport, protein synthesis, protein folding, response to stress and inflammation. This suggests higher metabolic activity as well as increased cell stress in the omental compared to the subcutaneous fat. These findings provide some insights into the role of omental fat in abdominal obesity-associated co-morbidities.; This work was supported by Grant SAF-2006-02354 and Grant SAF-2008-02073 from the Ministerio de Educación y Ciencia...

9 pages, 4 tables, 3 figures.-- Research article.; [EN] The n-Alkene content in samples of subcutaneous fat corresponding to 755 castrated male Iberian pigs has been determined by an off-line combination of HPLC and GC method. The samples corresponded to three groups based on the type of feeding during the finish fattening period (“Montanera”, fed on acorns and pasture; “Recebo”, fed on acorns, feed and pasture; and “Cebo”, fed on feed and pasture). By using the n-alkenes as chemical descriptors, multivariate statistical techniques were applied to differentiate between the three fattening diet types for Iberian pigs. The most differentiating variables were n-C16:1, n-C18:1, n-C22:1 and n-C24:1. However, a clear classification of the samples was not achieved. The level of classification was improved when the data corresponding to the animals fed with the “Recebo” fattening diet was removed from the analysis. A relationship between n-C14:1, n-C16:1 and n-C18:1 levels and the slaughter period was found to be very low for the animals fed with the “Cebo” fattening diet when the animals had not been closely managed and pasture had not been included in their fattening diet.; [ES] El contenido de n-alquenos de la grasa subcutánea de 755 muestras procedentes de cerdos ibéricos machos...

10 pages, 3 figures, 4 tables.-- Review article of V World Congress of dry-cured Ham.; [EN] Fatty acid and triacylglycerol compositions of 200 samples of subcutaneous fat from two different anatomical locations (rump and adipose tissue covering the Biceps femoris muscle) of Iberian purebred pigs reared on “Montanera” were determined. Significant differences were found for the majority fatty acids and for some triacylglycerol species (PPS, PLPo + MLO, PLO, PLL + PoLO, SOS, SOL, OLL) among the two anatomical locations, being the rump location less saturated. The activity level of the key enzyme involved in lipogenesis differed (p 0.0001) significantly between both tissues. The effect of campaign on the fatty acid and triacylglycerol composition was also explored. An increase on the ratio oleic/stearic has been found in campaigns with low resources. This indicates an increase on the activity of Stearoyl-CoA desaturase. Besides, the differences found between both subcutaneous fats during the fattening period indicates that the unsaturation of the subcutaneous fat covering a muscle with high oxidative metabolism, as Biceps femoris, increases faster than that of the subcutaneous fat covering a muscle with low oxidative metabolism...

The aim of this experiment was to evaluate the productive and economic performance and quantitative traits of crossbreds half Dorper half Santa Inês (½ D-SI) lambs carcasses and purebreds Santa Inês (SI) slaughtered with different subcutaneous fat thicknesses. Thirty-four lambs were used, sixteen were SI and eighteen were ½ D-SI. The lambs were kept confined and received a diet to provide an average daily weight gain of 0.300 kg. Weekly weightings and admeasurements of subcutaneous fat thicknesses through ultrasonography (between the 12ª and 13ª ribs) were made, and the lambs were killed as the predetermined fat thicknesses (2.0; 3.0 and 4.0 mm) were reached. There wasn’t breed effect on the productive performance. Concerning to subcutaneous fat thicknesses, it was noticed an advantage on the animals final weight when these were killed with 4.0 mm. This advantage was of 7.86 and 3.81 kg more compared to those animals that were killed with 2.0 and 3.0 mm respectively. There was differences on food ingestion between all the fat thicknesses. Furthermore, the lambs killed with subcutaneous fat thicknesses of 2.0 and 3.0 mm had a better feed conversion rate (FCR) when compared to the ones killed with 4.0 mm. The economical evaluation expressed in absolute values provided an increased net income as the subcutaneous fat thickness would increase. The commercial and biological returns were affected by fat thicknesses at slaughter and both variables were bigger on thicknesses of 4.0 mm followed by 3.0 and finally 2.0 mm. About meat cuts...

Peak growth velocity, especially of height (PHV), is the most used indicator of somatic maturity in longitudinal studies of adolescents. The objectives of this study were: a) to describe the time and magnitude of the peak height velocity (PHV), the peak weight velocity (PWV), and the peak subcutaneous fat velocity (PSFV) of a group of boys and girls followed from 10 to 14 years of age, b) to compare these variables between sexes, and c) to relate the time and magnitude of the three peaks with each other. The study sample was made up of 70 schoolchildren (35 boys and 35 girls) who were followed from age 10 to age 14. The results demonstrated that the peak growth velocity of the three variables occurred at 12 to 13 years old among the boys, and two years earlier among the girls. Only the magnitude of PSFV exhibited signifi cant difference, with the girls having higher values. The periods during which PHV, PWV, and PSFV occurred, did not present any significant correlations with each other. Nevertheless, the individual analyses indicated that, in a large proportion of the subjects, peak velocities occurred at the same time, or PSFV occurred one year later than PHV. Based on these results, we conclude that PHV, PWV, and PSFV occur about two years earlier among girls...
