    Full Text Available Taeyeumjoweetang (TYJWT is a herbal medication that was mentioned in Jema Lee's Donguisusebowon, which is a book about Sasang constitutional medicine. Tae-eumnis, one of the four constitutions, tend to suffer from metabolic diseases such as obesity and diabetes. It is widely used to treat the digestive problems and obesity of Tae-eumins. We divided mice that were fed a normal diet for 48 days into control, TYJWT 250 mg kg-1 and TYJWT 500 mg kg-1 groups. After carrying out the experiments, the serum levels of leptin, adiponectin, ghrelin and resistin were measured. The results showed that TYJWT significantly reduced the weights of mice that were fed a normal diet, and that this was due to a decrease in food intake. Also, the two TYJWT groups had lower serum levels of leptin compared to the control group, and the ghrelin levels were proportionately increased by the dosage of TYJWT given. These results show that TYJWT has obesity-suppressing effects similar to those previously reported using high fat diets. In addition, these results also provide evidence that TYJWT has anti-obesity effects.

    Although obesity is associated with osteoarthritis, it is unclear whether body weight (BW) independently affects articular cartilage catabolism (i.e., independent from physiological factors that also accompany obesity). The primary purpose of this study was to evaluate the independent effect of BW on articular cartilage catabolism associated with walking. A secondary purpose was to determine how decreased BW influenced cardiovascular response due to walking. Twelve able-bodied subjects walked for 30 minutes on a lower-body positive pressure treadmill during three sessions: control (unadjusted BW), +40%BW, and -40%BW. Serum cartilage oligomeric matrix protein (COMP) was measured immediately before (baseline) and after, and 15 and 30 minutes after the walk. Heart rate (HR) and rate of perceived exertion (RPE) were measured every three minutes during the walk. Relative to baseline, average serum COMP concentration was 13% and 5% greater immediately after and 15 minutes after the walk. Immediately after the walk, serum COMP concentration was 14% greater for the +40%BW session than for the -40%BW session. HR and RPE were greater for the +40%BW session than for the other two sessions, but did not differ between the control and -40%BW sessions. BW independently influences acute articular cartilage catabolism and cardiovascular response due to walking: as BW increases, so does acute articular cartilage catabolism and cardiovascular response. These results indicate that lower-body positive pressure walking may benefit certain individuals by reducing acute articular cartilage catabolism, due to walking, while maintaining cardiovascular response. Key pointsWalking for 30 minutes with adjustments in body weight (normal body weight, +40% and -40% body weight) significantly influences articular cartilage catabolism, measured via serum COMP concentration.Compared to baseline levels, walking with +40% body weight and normal body weight both elicited significant increases in

    Hatchery-reared salmonids often contain proportionally greater amounts of body lipid (storage fat) and proportionally lesser amounts of body protein (muscle) and ash (bone) than do their wild counterparts of equal size. The effect of body composition on postrelease survival and subsequent return of mature adults is presently unknown. High lipid deposits may benefit the fish by providing reserve energy during adaptation to the wild, or may hinder the fish by delaying

  6. Does affective touch influence the virtual reality full body illusion?

    The sense of how we experience our physical body as our own represents a fundamental component of human self-awareness. Body ownership can be studied with bodily illusions which are generated by inducing a visuo-tactile conflict where individuals experience illusionary ownership over a fake body or body part, such as a rubber hand. Previous studies showed that different types of touch modulate the strength of experienced ownership over a rubber hand. Specifically, participants experienced more ownership after the rubber hand illusion was induced through affective touch vs non-affective touch. It is, however, unclear whether this effect would also occur for an entire fake body. The aim of this study was, therefore, to investigate whether affective touch modulates the strength of ownership in a virtual reality full body illusion. To elicit this illusion, we used slow (3 cm/s; affective touch) and fast (30 cm/s; non-affective touch) stroking velocities on the participants' abdomen. Both stroking velocities were performed either synchronous or asynchronous (control condition), while participants viewed a virtual body from a first-person-perspective. In our first study, we found that participants experienced more subjective ownership over a virtual body in the affective touch condition, compared to the non-affective touch condition. In our second study, we found higher levels of subjective ownership for synchronous stimulation, compared to asynchronous, for both touch conditions, but failed to replicate the findings from study 1 that show a difference between affective and non-affective touch. We, therefore, cannot conclude unequivocally that affective touch enhances the full-body illusion. Future research is required to study the effects of affective touch on body ownership.

Inspired by a study from Japan, we introduce culture as a variable in the experiment and discuss the difficulties...... of cross-cultural comparisons. The results show that there are certain age-related differences in the perception of affective body movements, but not as strong as in the original study.

    Previous research has revealed affect-congruity effects for the recognition of affects from faces. Little is known about the impact of affect on the perception of body language. The aim of the present study was to investigate the relationship of implicit (versus explicit) affectivity with the recognition of briefly presented affective body expressions. Implicit affectivity, which can be measured using indirect assessment methods, has been found to be more predictive of spontaneous physiological reactions than explicit (self-reported) affect. Thirty-four healthy women had to label the expression of body postures (angry, fearful, happy, or neutral) presented for 66 ms and masked by a neutral body posture in a forced-choice format while undergoing functional magnetic resonance imaging (fMRI). Participants' implicit affectivity was assessed using the Implicit Positive and Negative Affect Test. Measures of explicit state and trait affectivity were also administered. Analysis of the fMRI data was focused on a subcortical network involved in the rapid perception of affective body expressions. Only implicit negative affect (but not explicit affect) was correlated with correct labeling performance for angry body posture. As expected, implicit negative affect was positively associated with activation of the subcortical network in response to fearful and angry expression (compared to neutral expression). Responses of the caudate nucleus to affective body expression were especially associated with its recognition. It appears that processes of rapid recognition of affects from body postures could be facilitated by an individual's implicit negative affect. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    We propose that women regularly anticipate and receive messages from others that trivialize the severity of their body image concerns. Moreover, we suggest that these minimizing messages can heighten women's negative affective reactions to body image threats, particularly if they internalize them. Two studies provided support for these ideas. In…

    Most research on emotion recognition focuses on facial expressions. However, people communicate emotional information through bodily cues as well. Prior research on facial expressions has demonstrated that emotion recognition is modulated by top-down processes. Here, we tested whether this top-down modulation generalizes to the recognition of emotions from body postures. We report three studies demonstrating that stereotypes and prejudice about men and women may affect how fast people classify various emotional body postures. Our results suggest that gender cues activate gender associations, which affect the recognition of emotions from body postures in a top-down fashion.

    The study of body image-related problems in non-Western countries is still very limited. Thus, this study aims to identify the main influential sources and show how they affect the body image perceptions of Bangkok adolescents. The researcher recruited 400 Thai male and female adolescents in Bangkok, attending high school to freshmen level, ranging from 16-19 years, to participate in this study. Survey questionnaires were distributed to every student and follow-up interviews conducted with 40 students. The findings showed that there are eight main influential sources respectively ranked from the most influential to the least influential: magazines, television, peer group, familial, fashion trend, the opposite gender, self-realization and health knowledge. Similar to those studies conducted in Western countries, more than half of the total percentage was the influence of mass media and peer groups. Bangkok adolescents also internalized Western ideal beauty through these mass media channels. Alike studies conducted in the West, there was similarities in the process of how these influential sources affect Bangkok adolescent body image perception, with the exception of familial source. In conclusion, taking the approach of identifying the main influential sources and understanding how they affect adolescent body image perceptions can help prevent adolescents from having unhealthy views and taking risky measures toward their bodies. More studies conducted in non-Western countries are needed in order to build a cultural sensitive program, catered to the body image problems occurring in adolescents within that particular society.

  12. Mirror Box Training in Hemiplegic Stroke Patients Affects Body Representation

    The brain integrates multisensory inputs coming from the body (i.e., proprioception, tactile sensations) and the world that surrounds it (e.g., visual information). In this way, it is possible to build supra-modal and coherent mental representations of our own body, in order to process sensory events and to plan movements and actions in space. Post-stroke acquired motor deficits affect the ability to move body parts and to interact with objects. This may, in turn, impair the brain representation of the affected body part, resulting in a further increase of disability and motor impairment. To the aim of improving any putative derangements of body representation induced by the motor deficit, here we used the Mirror Box (MB). MB is a rehabilitative tool aimed at restoring several pathological conditions where body representation is affected, including post-stroke motor impairments. In this setting, observing the reflection of the intact limb in the mirror, while the affected one is hidden behind the mirror, can exert a positive influence upon different clinical conditions from chronic pain to motor deficits. Such results are thought to be mediated by a process of embodiment of the mirror reflection, which would be integrated into the representation of the affected limb. A group of 45 post-stroke patients was tested before and after performing a MB motor training in two conditions, one with the mirror between the hands and one without it, so that patients could see their impaired limb directly. A forearm bisection task, specifically designed to measure the metric representation of the body (i.e., size), was used as dependent variable. Results showed that, at baseline, the forearm bisection is shifted proximally, compatibly with a shrink of the metric representation of the affected arm towards the shoulder. However, following the MB session bisection scores shifted distally, compatibly with a partial correction of the metric representation of that arm. The effects

    Cognitive behavioural models postulate that individuals with BDD engage in negative appearance-related appraisals and affect. External representations of one's appearance are thought to activate a specific mode of processing characterized by increased self-focused attention and an activation of negative appraisals and affect. The present study used a think-aloud approach including an in vivo body exposure to examine body-related cognitions and affect in individuals with BDD (n = 30), as compared to individuals with major depression (n = 30) and healthy controls (n = 30). Participants were instructed to think aloud during baseline, exposure and follow-up trials. Individuals with BDD verbalized more body-related and more negative body-related cognitions during all trials and reported higher degrees of negative affect than both control groups. A weaker increase of positive body-related cognitions during exposure, a stronger increase of sadness and anger after exposure and higher levels of post-event processing, were specific processes in individuals with BDD. Individuals with major depression were not excluded from the BDD group. This is associated with a reduction of internal validity, as the two clinical groups are somewhat interwoven. Key findings need to be replicated. The findings indicate that outcomes such as negative appearance-related cognitions and affect are specific to individuals with BDD. An external representation of one's appearance activates a specific mode of processing in BDD, manifesting itself in the absence of positive body-related cognitions, increased anger and sadness, and high levels of post-event processing. These specific processes may contribute toward maintenance of BDD psychopathology. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Heat shock factor 1 (HSF1) is a ubiquitous heat-sensitive transcription factor that mediates heat shock protein transcription in response to cellular stress, such as increased temperature, in order to protect the organism against misfolded proteins. In this study, we analysed the effect of HSF1 deficiency on core body temperature regulation. Body temperature, locomotor activity, and food consumption of wild-type mice and HSF1-deficient mice were recorded. Prolactin and thyroid-stimulating hormone levels were measured by ELISA. Gene expression in brown adipose tissue was analysed by quantitative real-time PCR. Hypothalamic HSF1 and its co-localisation with tyrosine hydroxylase was analysed using confocal laser scanning microscopy. HSF1-deficient mice showed an increase in core body temperature (hyperthermia), decreased overall locomotor activity, and decreased levels of prolactin in pituitary and blood plasma reminiscent of cold adaptation. HSF1 could be detected in various hypothalamic regions involved in temperature regulation, suggesting a potential role of HSF1 in hypothalamic thermoregulation. Moreover, HSF1 co-localises with tyrosine hydroxylase, the rate-limiting enzyme in dopamine synthesis, suggesting a potential role of HSF1 in the hypothalamic control of prolactin release. In brown adipose tissue, levels of prolactin receptor and uncoupled protein 1 were increased in HSF1-deficient mice, consistent with an up-regulation of heat production. Our data suggest a role of HSF1 in systemic thermoregulation. © 2015 S. Karger AG, Basel.

  6. Do air-gaps behind soft body armour affect protection?

    Science.gov (United States)

    Tilsley, Lee; Carr, D J; Lankester, C; Malbon, C

    2018-02-01

    Body armour typically comprises a fabric garment covering the torso combined with hard armour (ceramic/composite). Some users wear only soft armour which provides protection from sharp weapons and pistol ammunition. It is usually recommended that body armour is worn against the body with no air-gaps being present between the wearer and the armour. However, air-gaps can occur in certain situations such as females around the breasts, in badly fitting armour and where manufacturers have incorporated an air-gap claiming improvements in thermophysiological burden. The effect of an air-gap on the ballistic protection and the back face signature (BFS) as a result of a non-perforating ballistic impact was determined. Armour panels representative of typical police armour (400x400 mm) were mounted on calibrated Roma Plastilina No 1 and impacted with 9 mm Luger FMJ (9×19 mm; full metal jacket; Dynamit Nobel DM11A1B2) ammunition at 365±10 m/s with a range of air-gaps (0-15 mm). Whether or not the ammunition perforated the armour was noted, the BFS was measured and the incidence of pencilling (a severe, deep and narrow BFS) was identified. For 0° impacts, a critical air-gap size of 10 mm is detrimental to armour performance for the armour/ammunition combination assessed in this work. Specifically, the incidences of pencilling were more common with a 10 mm air-gap and resulted in BFS depth:volume ratios ≥1.0. For impacts at 30° the armour was susceptible to perforation irrespective of air-gap. This work suggested that an air-gap behind police body armour might result in an increased likelihood of injury. It is recommended that body armour is worn with no air-gap underneath. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

  7. Does smoking affect body weight and obesity in China?

    Science.gov (United States)

    Fang, Hai; Ali, Mir M; Rizzo, John A

    2009-12-01

    An inverse relationship between smoking and body weight has been documented in the medical literature, but the effect of cigarette smoking on obesity remains inconclusive. In addition, the evidence is mixed on whether rising obesity rates are an unintended consequence of successful anti-smoking policies. This study re-examines these relationships using data from China, the largest consumer and manufacturer of tobacco in the world that is also experiencing a steady rise in obesity rates. We focus on the impact of the total number of cigarettes smoked per day on individuals' body mass index (BMI) and on the likelihood of being overweight and obese. Instrumental variables estimation is used to correct for the endogeneity of cigarette smoking. We find a moderate negative and significant relationship between cigarette smoking and BMI. Smoking is also negatively related to being overweight and obese, but the marginal effects are small and statistically insignificant for being obese. Quantile regression analyses reveal that the association between smoking and BMI is quite weak among subjects whose BMIs are at the high end of the distribution but are considerably stronger among subjects in the healthy weight range. Ordered probit regression analyses also confirm these findings. Our results thus reconcile an inverse average effect of smoking on body weight with the absence of any significant effect on obesity. From a policy perspective these findings suggest that, while smoking cessation may lead to moderate weight gain among subjects of healthy weight, the effects on obese subjects are modest and should not be expected to lead to a large increase in obesity prevalence rates.

We found that drum-breaks with medium degrees of syncopation were associated with the same amount of acceleration and synchronisation as low degrees of syncopation. Participants who enjoyed dancing made more complex movements than those who did not enjoy dancing. While for all participants hand movements accelerated more and were more complex, torso movements were more synchronised to the beat. Overall, movements were mostly synchronised to the main beat and half-beat level, depending on the body-part. We demonstrate that while people do not move or synchronise much to rhythms with high syncopation when dancing spontaneously to music, the relationship between rhythmic complexity and synchronisation is less linear than in simple finger-tapping studies.

    Full Text Available For K-12 students, obesity has been linked to student educational achievements. The study objective was to determine whether academic performance in university students is correlated with BMI. Students from two consecutive academic years (Jan–May 2013 and Jan–May 2014 were given an optional class survey in May, as extra credit. Of the 452 students that completed the survey, 204 females and 75 males (N = 279; 73% female and 27% male consented to participate in the study. The number of correct answers to problem-solving questions (PSQs and the overall final grade for the class were compared to the calculated BMI using linear regression with a Pearson's R correlation and unpaired t-tests. BMI was significantly negatively correlated with student's final grades (P = 0.001 Pearson's r = −0.190 and PSQs were positively correlated with final grades (P < 0.001; Pearson's r = 0.357. Our findings show a correlation between healthy body weight and improved academic performance. Further, the data suggest that future research in the area of body weight, diet, and exercise and any correlations of these with academic performance in college students are warranted.

    Many caterpillars have conspicuous eye-like markings, called eyespots. Despite recent work demonstrating the efficacy of eyespots in deterring predator attack, a fundamental question remains: Given their protective benefits, why have eyespots not evolved in more caterpillars? Using a phylogenetically controlled analysis of hawkmoth caterpillars, we show that eyespots are associated with large body size. This relationship could arise because (i) large prey are innately conspicuous; (ii) large prey are more profitable, and thus face stronger selection to evolve such defenses; and/or (iii) eyespots are more effective on large-bodied prey. To evaluate these hypotheses, we exposed small and large caterpillar models with and without eyespots in a 2 × 2 factorial design to avian predators in the field. Overall, eyespots increased prey mortality, but the effect was particularly marked in small prey, and eyespots decreased mortality of large prey in some microhabitats. We then exposed artificial prey to naïve domestic chicks in a laboratory setting following a 2 × 3 design (small or large size × no, small, or large eyespots). Predators attacked small prey with eyespots more quickly, but were more wary of large caterpillars with large eyespots than those without eyespots or with small eyespots. Taken together, these data suggest that eyespots are effective deterrents only when both prey and eyespots are large, and that innate aversion toward eyespots is conditional. We conclude that the distribution of eyespots in nature likely results from selection against eyespots in small caterpillars and selection for eyespots in large caterpillars (at least in some microhabitats).

    Background Body composition prediction equations using skinfolds are useful alternatives to advanced techniques, but their utility across diverse pediatric populations is unknown. Aim To evaluate published and new prediction equations across diverse samples of children with health conditions affecting growth and body composition. Subjects and Methods Anthropometric and dual-energy x-ray absorptiometry (DXA) body composition measures were obtained in children with Down syndrome (n=59), Crohn disease (n=128), steroid-sensitive nephrotic syndrome (n=67), and a healthy reference group (n=835). Published body composition equations were evaluated. New equations were developed for ages 3 to 21y using the healthy reference sample and validated in other groups and national survey data. Results Fat mass [FM], fat-free mass [FFM] and percent body fat [%BF]) from published equations were highly correlated with DXA-derived measures (r=0.71 to 0.98), but with poor agreement (mean difference: 2.4kg, −1.9kg, and 6.3% for FM, FFM and %BF). New equations produced similar correlations (r=0.85 to 1.0) with improved agreement for the reference group (0.2kg, 0.4kg, and 0.0% for FM, FFM and %BF, respectively), and in sub-groups. Conclusions New body composition prediction equations show excellent agreement with DXA, and improve body composition estimation in healthy children and those with selected conditions affecting growth.

    Webb, Jennifer B; Butler-Ajibade, Phoebe; Robinson, Seronda A

    2014-09-01

    The present study provided an initial evaluation of an affect regulation model describing the association between body dissatisfaction and two contemporary measures of positive body image among 247 Black college-bound older adolescent females. We further tested whether possessing a higher body mass index (BMI) would strengthen these associations. Self-reported height and weight were used to calculate BMI. Respondents also completed a culturally-sensitive figure rating scale along with assessments of body appreciation and body image flexibility. Results indicated a robust positive association between the two measures of positive body image; BMI was the strongest predictor of both body appreciation and body image flexibility with body size discrepancy (current minus ideal) contributing incremental variance to both models tested. Implications for improving our understanding of the association between positive and negative body image and bolstering positive body image to promote health-protective behaviors among Black young women at this developmental juncture are discussed.

    Many bariatric surgery candidates report body image concerns before surgery. Research has reported post-surgical improvements in body satisfaction, which may be associated with weight loss. However, research has failed to comprehensively examine changes in affective, behavioral, and cognitive body image. This research examined (1) short-term changes in affective, behavioral, and cognitive components of body image from pre-surgery to 1- and 6-months after bariatric surgery, and (2) the association between percent weight loss and these changes. Participants were recruited from a private hospital in the midwestern United States. Eighty-eight females (original N = 123; lost to follow-up: n = 15 at 1-month and n = 20 at 6-months post-surgery) completed a questionnaire battery, including the Body Attitudes Questionnaire, Body Checking Questionnaire, Body Image Avoidance Questionnaire, and Body Shape Questionnaire, and weights were obtained from patients' medical records before and at 1- and 6-months post-surgery. Results indicated significant decreases in body dissatisfaction, feelings of fatness, and body image avoidance at 1- and 6-months after bariatric surgery, with the greatest magnitude of change occurring for body image avoidance. Change in feelings of fatness was significantly correlated with percent weight loss at 6-months, but not 1-month, post-surgery. These findings highlight the importance of examining short-term changes in body image from a multidimensional perspective in the effort to improve postsurgical outcomes. Unique contributions include the findings regarding the behavioral component of body image, as body image avoidance emerges as a particularly salient concern that changes over time among bariatric surgery candidates.

    2009-06-01

    A recent experimental study found that activation of negative body image cognitions produced urges to smoke in young women (E. N. Lopez, D. J. Drobes, J. K. Thompson, & T. H. Brandon, 2008). This study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N=133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and postmanipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation and that this effect occurs, at least in part, through increases in negative affect. Theoretical and applied implications are discussed. Copyright (c) 2009 APA, all rights reserved.

  16. The Differential Effects of Mindfulness and Distraction on Affect and Body Satisfaction Following Food Consumption

    Full Text Available This study investigated whether engaging in mindfulness following food consumption produced changes in affect and body satisfaction, as compared to a control distraction task. The moderating effects of eating pathology and neuroticism were also examined. A total of 110 female university students consumed food and water before engaging in either a mindfulness induction or a control distraction task. Participants completed trait measures of eating pathology and neuroticism at baseline, and measures of state affect and body satisfaction before and after food consumption, and after the induction. Results revealed that consuming food and water reduced positive affect. Unexpectedly, both the mindfulness group and distraction control group experienced similar improvements in negative affect and body satisfaction following the induction. Eating pathology and neuroticism did not moderate the observed changes. These findings suggest that both mindfulness and distraction may contribute to the effectiveness of treatments for disordered eating that incorporate both of these techniques, such as Dialectical Behavior Therapy.

    The brain integrates multiple sensory inputs, including somatosensory and visual inputs, to produce a representation of the body. Spinal cord injury (SCI) interrupts the communication between brain and body and the effects of this deafferentation on body representation are poorly understood. We investigated whether the relative weight of somatosensory and visual frames of reference for body representation is altered in individuals with incomplete or complete SCI (affecting lower limbs' somatosensation), with respect to controls. To study the influence of afferent somatosensory information on body representation, participants verbally judged the laterality of rotated images of feet, hands, and whole-bodies (mental rotation task) in two different postures (participants' body parts were hidden from view). We found that (i) complete SCI disrupts the influence of postural changes on the representation of the deafferented body parts (feet, but not hands) and (ii) regardless of posture, whole-body representation progressively deteriorates proportionally to SCI completeness. These results demonstrate that the cortical representation of the body is dynamic, responsive, and adaptable to contingent conditions, in that the role of somatosensation is altered and partially compensated with a change in the relative weight of somatosensory versus visual bodily representations.

    Leptin has a significant role in body weight regulation and energy balance. We examined the effect of tibolone on the body weight and serum leptin levels in postmenopausal women. Twenty women (aged 43-60 years) participated in this prospective study. All women in this study protocol received 2.5 mg/day of tibolone. Absolute and body mass index (BMI)-corrected serum leptin concentrations and BMI values were measured at baseline, after 3 months, and after 6 months of the tibolone therapy. Tibolone did not affect absolute and BMI-corrected serum leptin levels, and BMI values during the treatment. A significant linear correlation between BMI values and serum leptin levels was observed (p<0.05, r=0.67). Tibolone seems not to affect serum leptin levels, body weight and BMI values of postmenopausal women. There is a significant correlation between serum leptin levels and BMI values.

    In vitro and animal data suggest that quercetin affects adipogenesis and basal metabolism; however, whether this metabolic effect translates to reductions in body mass or improvement in body composition in humans is unknown. This study investigated 12-week supplementation of 2 different doses of quercetin, combined with vitamin C and niacin, on body mass and composition in a large, heterogeneous group of adults (n = 941; 60% female, 40% male; 18-85 years of age; 45% normal body mass index, 30% overweight, 25% obese). Subjects were randomized into 3 groups, with supplements administered in double-blind fashion: Q500 = 500 mg quercetin·day(-1), Q1000 = 1000 mg quercetin·day(-1), and placebo. Quercetin supplements were consumed twice daily over a 12-week period, and pre- and poststudy body mass and composition measurements were taken in an overnight fasted state. A general linear model was used to predict change in body mass and composition across groups with adjustment for demographic and lifestyle factors. Plasma quercetin increased in a dose-responsive manner in both Q500 and Q1000 groups relative to placebo. After adjustment for confounders, no significant differences in body mass (males interaction p value = 0.721, females p = 0.366) or body composition (males p = 0.650, females p = 0.639) were found between Q500 or Q1000 groups compared with placebo. No group differences in body mass or body composition were found in a subgroup of overweight and obese subjects. High-dose quercetin supplementation (500 and 1000 mg·day(-1)) for 12 weeks in a large, heterogeneous group of adults did not affect body mass or composition.

    Previous body image research suggests that first, exposure to body stimuli can negatively affect men's body satisfaction and second, body concerns are associated with dysfunctional gaze behavior. To date, however, the effects of self- vs. other-referential body stimuli and of gaze behavior on body image in men under exposure conditions have not been investigated. Therefore, 49 weight-trained men were presented with pictures of their own and other bodies of different builds (i.e., normal, muscular, hyper-muscular) while being eye-tracked. Participants completed pre- and post-exposure measures of body image and affect. Results indicated that one's own and the muscular body negatively affected men's body image to a comparable degree. Exposure to one's own body also led to increased negative affect. Increased attention toward disliked own body parts was associated with a more negative post-exposure body image and affect. These results suggest a crucial role of critical self-examination in maintaining body dissatisfaction. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The present study shows how motor expertise increases individuals' sensitivity to others' affective body movement. This enhanced sensitivity is evident in the experts' behavior and physiology. Nineteen affective movement experts (professional ballet dancers) and 24 controls watched 96 video clips of emotionally expressive body movements while they performed an affect rating task (subjective response), and their galvanic skin response was recorded (physiological response). The movements in the clips were either sad or happy, and in half of the trials, movements were played in the order in which they are learned (forward presentation), and in the other half, movements were played backward (control condition). Results showed that motor expertise in affective body movement specifically modulated both behavioral and physiological sensitivity to others' affective body movement, and that this sensitivity is particularly strong when movements are shown in the way they are learnt (forward presentation). The evidence is discussed within current theories of proprioceptive arousal feedback and motor simulation accounts. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Full Text Available Large-bodied reef fishes represent an economically and ecologically important segment of the coral reef fish assemblage. Many of these individuals supply the bulk of the reproductive output for their population and have a disproportionate effect on their environment (e.g. as apex predators or bioeroding herbivores. Large-bodied reef fishes also tend to be at greatest risk of overfishing, and their loss can result in a myriad of either cascading (direct or indirect trophic and other effects. While many studies have investigated habitat characteristics affecting populations of small-bodied reef fishes, few have explored the relationship between large-bodied species and their environment. Here, we describe the distribution of the large-bodied reef fishes in the Mariana Archipelago with an emphasis on the environmental factors associated with their distribution. Of the factors considered in this study, a negative association with human population density showed the highest relative influence on the distribution of large-bodied reef fishes; however, depth, water temperature, and distance to deep water also were important. These findings provide new information on the ecology of large-bodied reef fishes can inform discussions concerning essential fish habitat and ecosystem-based management for these species and highlight important knowledge gaps worthy of additional research.

    Alpha-ketoglutarate (AKG), a precursor of glutamate and a critical intermediate in the tricarboxylic acid cycle, shows beneficial effects on intestinal function. However, the influence of AKG on the intestinal innate immune system and intestinal microbiota is unknown. This study explores the effect of oral AKG administration in drinking water (10 g/L) on intestinal innate immunity and intestinal microbiota in a mouse model. Mouse water intake, feed intake and body weight were recorded throughout the entire experiment. The ileum was collected for detecting the expression of intestinal proinflammatory cytokines and innate immune factors by Real-time Polymerase Chain Reaction. Additionally, the ileal luminal contents and feces were collected for 16S rDNA sequencing to analyze the microbial composition. The intestinal microbiota in mice was disrupted with an antibiotic cocktail. The results revealed that AKG supplementation lowered body weight, promoted ileal expression of mammalian defensins of the alpha subfamily (such as cryptdins-1, cryptdins-4, and cryptdins-5) while influencing the intestinal microbial composition (i.e., lowering the Firmicutes to Bacteroidetes ratio). In the antibiotic-treated mouse model, AKG supplementation failed to affect mouse body weight and inhibited the expression of cryptdins-1 and cryptdins-5 in the ileum. We concluded that AKG might affect body weight and intestinal innate immunity through influencing intestinal microbiota.

    Full Text Available Abstract Oesophageal foreign bodies are common in dogs. Endoscopic removal is a viable treatment option but few studies have assessed the clinical and radiographic features that would be useful in decision-making and prognosis. Dogs (n = 44 with oesophageal foreign bodies presented to the University Veterinary Hospital were assessed. Terriers and West Highland White Terriers were significantly overrepresented (p Group 1 (n = 30 included animals where endoscopic removal was successful and Group 2 (n = 14 animals where it was unsuccessful or not attempted because of evidence of oesophageal rupture. There was no statistically significant difference in age, sex, body weight, type, location and size of foreign body, recovery rate, short-term complications and long-term outcome between the two groups. Duration of signs prior to presentation and time to spontaneous oral feeding were significantly longer (p Terriers appear predisposed to oesophageal foreign bodies. Success of endoscopic removal is adversely affected by duration of signs prior to presentation. Surgical removal negatively influences time to recovery. Stricture formation appears to be a relatively common complication and alternate measures for its prevention should be sought.

    Limited research has been conducted that elucidates the growth and body composition of preterm infants. It is known that these infants do not necessarily achieve extra-utero growth rates and body composition similar to those of their term counterparts. Preterm infants, who have difficulty in achieving these growth rates, could suffer from growth failure. These infants display an increased intra-abdominal adiposity and abnormal body composition when they achieve catch-up growth. These factors affect the quality of weight gain, as these infants are not only shorter and lighter than term infants, they also have more fat mass (FM) and less fat-free mass (FFM), resulting in a higher total fat percentage. This could cause metabolic syndrome and cardiovascular problems to develop later in a preterm infant's life. The methods used to determine body composition in preterm infants should be simple, quick, non-invasive and inexpensive. Available literature was reviewed and the Dauncey anthropometric model, which includes skinfold thickness at two primary sites and nine body dimensions, is considered in this review the best method to accurately determine body composition in preterm infants, especially in resource-poor countries. It is imperative to accurately assess the quality of growth and body composition of this fragile population in order to determine whether currently prescribed nutritional interventions are beneficial to the overall nutritional status and quality of life-in the short- and long-term-of the preterm infant, and to enable timely implementation of appropriate interventions, if required.

We sought to determine whether acute dietary changes could induce or rescue wake impairments independent of body weight. Design: We implemented a novel feeding paradigm that generates two groups of mice with equal body weight but opposing energetic balance. Two subsets of mice consuming either regular chow (RC) or high-fat diet (HFD) for 8 w were switched to the opposite diet for 1 w. Sleep recordings were conducted at Week 0 (baseline), Week 8 (pre-diet switch), and Week 9 (post-diet switch) for all groups. Sleep homeostasis was measured at Week 8 and Week 9. Participants: Young adult, male C57BL/6J mice. Measurements and Results: Differences in total wake, nonrapid eye movement (NREM), and rapid eye movement (REM) time were quantified, in addition to changes in bout fragmentation/consolidation. At Week 9, the two diet switch groups had similar body weight. However, animals switched to HFD (and thus gaining weight) had decreased wake time, increased NREM sleep time, and worsened sleep/wake fragmentation compared to mice switched to RC (which were in weight loss). These effects were driven by significant sleep/wake changes induced by acute dietary manipulations (Week 8 → Week 9). Sleep homeostasis, as measured by delta power increase following sleep deprivation, was unaffected by our feeding paradigm. Conclusions: Acute dietary manipulations are sufficient to alter sleep and wakefulness independent of body weight and without effects on sleep homeostasis. Citation: Perron IJ, Pack AI, Veasey S.

    Successful restoration of wetland ecosystems requires knowledge of wetland hydrologic patterns and an understanding of how those patterns affect wetland plant and animal populations.Within the Everglades, Florida, USA restoration, an applied science strategy including conceptual ecological models linking drivers to indicators is being used to organize current scientific understanding to support restoration efforts. A key driver of the ecosystem affecting the distribution and abundance of organisms is the timing, distribution, and volume of water flows that result in water depth patterns across the landscape. American alligators (Alligator mississippiensis) are one of the ecological indicators being used to assess Everglades restoration because they are a keystone species and integrate biological impacts of hydrological operations through all life stages. Alligator body condition (the relative fatness of an animal) is one of the metrics being used and targets have been set to allow us to track progress. We examined trends in alligator body condition using Fulton’s K over a 15 year period (2000–2014) at seven different wetland areas within the Everglades ecosystem, assessed patterns and trends relative to restoration targets, and related those trends to hydrologic variables. We developed a series of 17 a priori hypotheses that we tested with an information theoretic approach to identify which hydrologic factors affect alligator body condition. Alligator body condition was highest throughout the Everglades during the early 2000s and is approximately 5–10% lower now (2014). Values have varied by year, area, and hydrology. Body condition was positively correlated with range in water depth and fall water depth. Our top model was the “Current” model and included variables that describe current year hydrology (spring depth, fall depth, hydroperiod, range, interaction of range and fall depth, interaction of range and hydroperiod). Across all models, interaction

    We compared food intake, body mass and body composition of male and female black ducks (Anas rubripes) during winter (January-March). Birds were fed the same complete diet ad libitum on consecutive days each week without fasting (control; nine male; nine female) or with either short fasts (2 day.week-1; nine male; nine female), or long fasts (4 day.week-1; eleven male; twelve female). We continued treatments through spring (March-May) to measure the effect of intermittent fasts on body mass and egg production. Daily food intake of fasted birds was up to four times that of unfasted birds. Weekly food intake of males was similar among treatments (364 g.kg-1.week-1) but fasted females consumed more than unfasted females in January (363 g.kg-1.week-1 vs. 225 g.kg-1.week-1). Although both sexes lost 10-14% body mass, fasted females lost less mass and lipid than unfasted females during winter. Total body nitrogen was conserved over winter in both sexes even though the heart and spleen lost mass while the reproductive tract and liver gained mass. Intermittent fasting increased liver, intestinal tissue and digesta mass of females but not of males. Fasting delayed egg production in spring but did not affect size, fertility or hatching of the clutch. Females on long fasts were still heavier than controls after laying eggs. Thus black ducks combine flexibility of food intake with plasticity of digestive tract, liver and adipose tissue when food supply is interrupted during winter. Females modulate body mass for survival and defer reproduction when food supply is interrupted in spring.

    Quinine is a natural molecule commonly used as a flavouring agent in tonic water. Diet supplementation with quinine leads to decreased body weight and food intake in rats. Quinine is an in vitro inhibitor of Trpm5, a cation channel expressed in taste bud cells, the gastrointestinal tract and pancreas. The objective of this work is to determine the effect of diet supplementation with quinine on body weight and body composition in male mice, to investigate its mechanism of action, and whether the effect is mediated through Trpm5. Compared with mice consuming AIN, a regular balanced diet, mice consuming AIN diet supplemented with 0.1% quinine gained less weight (2.89 ± 0.30 g vs 5.39 ± 0.50 g) and less fat mass (2.22 ± 0.26 g vs 4.33 ± 0.43 g) after 13 weeks of diet, and had lower blood glucose and plasma triglycerides. There was no difference in food intake between the mice consuming quinine supplemented diet and those consuming control diet. Trpm5 knockout mice gained less fat mass than wild-type mice. There was a trend for a diet-genotype interaction for body weight and body weight gain, with the effect of quinine less pronounced in the Trpm5 KO than in the WT background. Faecal weight, energy and lipid contents were higher in quinine fed mice compared to regular AIN fed mice and in Trpm5 KO mice compared to wild type mice. Quinine contributes to weight control in male C57BL6 mice without affecting food intake. A partial contribution of Trpm5 to quinine dependent body weight control is suggested.

    Calcium intake is a potential factor influencing weight gain and may reduce body weight, but the evidence for this in children is conflicting. The aim of this study was to use data from randomized controlled trials to determine whether calcium supplementation in healthy children affects weight or body composition. This study is a systematic review. We identified potential studies by searching the following electronic bibliographic databases: CENTRAL, MEDLINE, EMBASE, CINAHL, AMED, MANTIS, ISI Web of Science, Food Science and Technology Abstracts, and Human Nutrition up until April 1, 2005 and hand-searched relevant conference abstracts. Studies were included if they were placebo-controlled randomized controlled trials of calcium supplementation, with at least 3 months of supplementation, in healthy children and with outcome measures including weight. Meta-analyses were performed using fixed effects models and weighted mean differences for weight and height and standardized mean differences (SMDs) for body composition measures. There were no statistically significant effects of calcium supplementation on weight [+0.14 kg; 95% confidence interval (CI), -0.28, +0.57 kg], height (+0.22 cm; 95% CI, -0.30, +0.74 cm), body fat (SMD, +0.04; 95% CI, -0.08, +0.15), or lean mass (SMD, +0.14; 95% CI, -0.03, +0.31). There is no evidence to support the use of calcium supplementation as a public health intervention to reduce weight gain or body fat in healthy children. Although our results do not rule out an effect of dietary supplementation with dairy products on weight gain or body composition, there is little evidence to support this hypothesis.

    Full Text Available The prediction of object stability on earth requires the establishment of a perceptual frame of reference based on the direction of gravity. Across three experiments, we measured the critical angle (CA at which an object appeared equally likely to fall over or right itself. We investigated whether the internal representation of the gravity direction, biased by either simulated tilt (rotating visual surround or real body tilt situations, influences in a similar fashion the judgment of stability. In the simulated tilt condition, the estimated CA and the perceived gravity are both deviated in the same direction. In the real tilt condition, the orientation of the body affects the perception of gravity direction but has no effect on the estimated CA. Results suggest that people differently weigh gravity direction information provided by visual motion and by visual polarity cues for estimating the stability of objects.

    Full Text Available Patients with conversion disorder generally suffer from a severe neurological deficit which cannot be attributed to a structural neurological damage. In two patients with acute conversion paraplegia, investigation with functional magnetic resonance imaging (fMRI showed that the insular cortex, a limbic-related cortex involved in body-representation and subjective emotional experience, was activated not only during attempt to move the paralytic body-parts, but also during mental imagery of their movements. In addition, mental rotation of affected body-parts was found to be disturbed, as compared to unaffected body parts or external objects. fMRI during mental rotation of the paralytic body-part showed an activation of another limbic related region, the anterior cingulate cortex. These data suggest that conversion paraplegia is associated with pathological activity in limbic structures involved in body representation and a deficit in mental processing of the affected body-parts.

    Postural sway during quiet standing reduces when somatosensorial information is provided by an active or passive "light touch" of different body parts with a surface. The contact of the safety harness with the body could induce a similar effect, leading to an undesirable side effect in the balance evaluation. This study investigated if a safety harness system, commonly used in balance studies, affects body sway during the balance evaluation. Healthy adults stood as quietly as possible for 60s in a comfortable position on a force plate. First, we performed an experiment on the light-touch effect with 10 subjects to determine the necessary sample size for the main investigation. Then, 60 subjects completed four tasks where the use of the safety harness and the visual information were manipulated. Area, root-mean square, speed, and frequency of the center of pressure displacement were analyzed. A light touch decreased postural sway on both visual conditions but there was no effect of the use of a safety harness on sway when quietly standing, independent of the visual information. Postural sway increased on both somatosensorial conditions when the visual information was not provided. This result shows that the safety harness does not interfere with the evaluation what is of major importance to methodological aspects of balance evaluation.

  5. Matrix Intensification Affects Body and Physiological Condition of Tropical Forest-Dependent Passerines.

    Full Text Available Matrix land-use intensification is a relatively recent and novel landscape change that can have important influences on the biota within adjacent habitat patches. While there are immediate local changes that it brings about, the influences on individual animals occupying adjacent habitats may be less evident initially. High-intensity land use could induce chronic stress in individuals in nearby remnants, leading ultimately to population declines. We investigated how physiological indicators and body condition measures of tropical forest-dependent birds differ between forest adjacent to surface mining sites and that near farmlands at two distances from remnant edge in southwest Ghana. We used mixed effects models of several condition indices including residual body mass and heterophil to lymphocyte (H/L ratios (an indicator of elevated chronic stress to explore the effect of matrix intensity on forest-dependent passerines classed as either sedentary area-sensitive habitat specialists or nomadic generalists. Individual birds occupying tropical forest remnants near surface mining sites were in poorer condition, as indicated by lower residual body mass and elevated chronic stress, compared to those in remnants near agricultural lands. The condition of the sedentary forest habitat specialists white-tailed alethe, Alethe diademata and western olive sunbird, Cyanomitra obscura was most negatively affected by high-intensity surface mining land-use adjacent to remnants, whereas generalist species were not affected. Land use intensification may set in train a new trajectory of faunal relaxation beyond that expected based on habitat loss alone. Patterns of individual condition may be useful in identifying habitats where species population declines may occur before faunal relaxation has concluded.

    Many studies show high prevalence of affective disorders in obese patients. Affective temperament is a subclinical manifestation of such conditions. The 5-HTT gene encoding the serotonin transporter may be involved in both mood and eating dysregulation. The aim of this study was to investigate the influence of a polymorphism in the 5-HTT gene on affective temperament types, depressive symptoms and Body Mass Index (BMI) in obese patients. This study involved 390 patients (237 females, and 153 males) with obesity. The TEMPS-A questionnaire, Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) were used to evaluate affective temperaments and prevalence of depression. DNA was obtained for serotonin transporter gene-linked polymorphism (5-HTTLPR) genotyping. In obese patients S/S genotype was associated with depressive and L/L with cyclothymic temperament. Subjects with L/L genotype presented significantly higher BMI and greater intensity of depressive symptoms in BDI and HDRS. Females scored higher in anxious and depressive, while males in hyperthymic, cyclothymic and irritable temperaments. Females scored higher in BDI (subjective depression) while males in HDRS (objective depression). TEMPS-A, BDI and HDRS are frequently used in studies on affective disorders. However, these methods do not examine all dimensions of mood and personality. In obese patients S allele of 5-HTTLPR was associated with development of depressive temperament while L allele corresponded with greater obesity and prevalence of depression. Different mechanisms may be involved in manifestation of depression in males and females with obesity. Copyright © 2015 Elsevier B.V. All rights reserved.

    Pro-anorexia websites portray an extreme form of thin-ideal. This between-subjects experiment examined the effects of viewing such a website on body satisfaction, affect, and appearance self-efficacy compared to viewing control websites (fashion, home decoration, automutilation). The sample consisted of 124 normal weight, young adult, Dutch women (mean age 21.2, mean body mass index 21.4). Participants did not differ on affect and appearance self-efficacy. One body satisfaction measure showed that pro-anorexia viewers were more satisfied with their bodies than home decoration viewers. Our findings suggest that viewing a pro-anorexia website might not have detrimental effects on body satisfaction and affect among normal weight young women.

One's initiation as a clown - as it is practiced at Lume: Interdisciplinary Centre for Theatrical Research at Unicamp - becomes an experience of 'becoming someone else', inventing other kinds of affection, involving an attitude of listening to the world with the whole body, in an alert state and, at the same time, of great dedication and availability. It is related to the resonances of encounters, of something that occurs between a clown and another person. The ethical, political, aesthetic and philosophical dimensions are imbricated in this aspect of affirmation of life, and in the construction of other modes of existence.

  10. The roles of the amygdala in the affective regulation of body, brain, and behaviour

    2010-09-01

    Despite the great amount of knowledge produced by the neuroscientific literature on affective phenomena, current models tackling non-cognitive aspects of behaviour are often bio-inspired but rarely bio-constrained. This paper presents a theoretical account of affective systems centred on the amygdala (Amg). This account aims to furnish a general framework and specific pathways to implement models that are more closely related to biological evidence. The Amg, which receives input from brain areas encoding internal states, innately relevant stimuli, and innately neutral stimuli, plays a fundamental role in the motivational and emotional processes of organisms. This role is based on the fact that Amg implements the two associative processes at the core of Pavlovian learning (conditioned stimulus (CS)-unconditioned stimulus (US) and CS-unconditioned response (UR) associations), and that it has the capacity of modulating these associations on the basis of internal states. These functionalities allow the Amg to play an important role in the regulation of the three fundamental classes of affective responses (namely, the regulation of body states, the regulation of brain states via neuromodulators, and the triggering of a number of basic behaviours fundamental for adaptation) and in the regulation of three high-level cognitive processes (namely, the affective labelling of memories, the production of goal-directed behaviours, and the performance of planning and complex decision-making). Our analysis is conducted within a methodological approach that stresses the importance of understanding the brain within an evolutionary/adaptive framework and with the aim of isolating general principles that can potentially account for the wider possible empirical evidence in a coherent fashion.

    'Theory of Mind' refers to the ability to attribute mental states, thoughts (cognitive component) or feelings (affective component), to others. This function has been studied in many neurodegenerative diseases; however, to our knowledge no studies investigating theory of mind in dementia with Lewy Bodies (DLB) have been published. The aim of our study was to search theory of mind deficits in patients with DLB. Seven patients with DLB (DLB group), at the stage of mild dementia or mild cognitive impairments, and seven healthy elderly adults (control group) were included in the study. After a global cognitive assessment, we used the Faux Pas Recognition test to assess the cognitive component of theory of mind, and the Reading the Mind in the Eyes test for the assessment of affective component. We found a significant difference between the two groups for the Faux Pas test with an average score of 35.6 for the DLB group and 48.3 for the control group (P=0.04). Scores were particularly low in the DLB group for the last question of the test concerning empathy (42.9% versus 85%, P=0.01). There was not a significant difference between the two groups for the Reading the Mind in the Eyes test (P=0.077). This preliminary study showed early impairments of theory of mind in the DLB. The cognitive component seems more affected than the affective component in this pathology. This pattern is consistent with the pattern found in Parkinson's disease, but differs from other neurodegenerative diseases as Alzheimer's disease or frontotemporal lobe dementia. These patterns may help to differentiate DLB from these diseases. Further study is needed to confirm these results and to compare with other dementias. Copyright © 2015 Elsevier Masson SAS.

    Understanding how animals react to human-induced changes in their environment is a key question in conservation biology. Owing to their potential correlation with fitness, several physiological parameters are commonly used to assess the effect of habitat disturbance on animals' general health status. Here, we studied how two lemur species, the fat-tailed dwarf lemur (Cheirogaleus medius) and the grey mouse lemur (Microcebus murinus), respond to changing environmental conditions by comparing their stress levels (measured as hair cortisol concentration), parasitism and general body condition across four habitats ordered along a gradient of human disturbance at Kirindy Forest, Western Madagascar. These two species previously revealed contrasting responses to human disturbance; whereas M. murinus is known as a resilient species, C. medius is rarely encountered in highly disturbed habitats. However, neither hair cortisol concentrations nor parasitism patterns (prevalence, parasite species richness and rate of multiple infections) and body condition varied across the gradient of anthropogenic disturbance. Our results indicate that the effect of anthropogenic activities at Kirindy Forest is not reflected in the general health status of both species, which may have developed a range of behavioural adaptations to deal with suboptimal conditions. Nonetheless, a difference in relative density among sites suggests that the carrying capacity of disturbed habitat is lower, and both species respond differently to environmental changes, with C. medius being more negatively affected. Thus, even for behaviourally flexible species, extended habitat deterioration could hamper long-term viability of populations.

    Weight gain and body fat increase the risk of cardiometabolic disease. Cross-sex hormone therapy in transgender persons leads to changes in body weight and body composition, but it is unclear to what extent. We performed a meta-analysis to investigate the changes in body weight, body fat and lean body mass during cross-sex hormone therapy in transgender persons. We searched the PubMed database for eligible studies until November 2015. Ten studies reporting changes in body weight, body fat or lean mass in hormone naive transgender persons were included, examining 171 male-to-female and 354 female-to-male transgender people. Pooled effect estimates in the male-to-female group were +1.8 kg (95% CI: 0.2;3.4) for body weight, +3.0 kg (2.0;3.9) for body fat and -2.4 kg (-2.8; -2.1) for lean body mass. In the female-to-male group, body weight changed with +1.7 kg (0.7;2.7), body fat with -2.6 kg (-3.9; -1.4) and lean body mass with +3.9 kg (3.2;4.5). Cross-sex hormone therapy increases body weight in both sexes. In the male-to-female group, a gain in body fat and a decline in lean body mass are observed, while the opposite effects are seen in the female-to-male group. Possibly, these changes increase the risk of cardiometabolic disease in the male-to-female group. © 2016 Blackwell Verlag GmbH.

    The purposes of this study were to identify correlations between body mass index, body image, and self-esteem in patients with schizophrenia and to analyse the specific factors affecting self-esteem. This study had a descriptive design, utilising a cross-sectional survey. Participants were patients with schizophrenia who were admitted to a mental health facility in South Korea. A total of 180 questionnaires were distributed, and an appropriate total sample size of 167 valid questionnaires was analysed. Self-esteem was significantly correlated with body image, the subscale of appearance orientation, and body areas satisfaction. However, body mass index exhibited no significant correlation with any variable. The variables found to have a significant explanatory power of 21.4% were appearance orientation and body areas satisfaction. The explanatory power of all factors was 33.6%. The self-esteem of patients with schizophrenia was influenced by body mass index and body image. The positive symptoms of schizophrenia can be controlled by medication, whereas negative symptoms can be improved through education and nursing care with medication. Thus, psychiatric nurses should develop education and care programs that contribute to the positive body image and self-esteem of patients with schizophrenia. Copyright © 2017 Elsevier Inc.

  16. The Performative Force of Bodies: Affective Realism in Contemporary Brazilian Cinema

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2015v68n3p161 This paper traces the emergence of a younger generation of Brazilian filmmakers whose works bypass traditional themes in Brazilian cinema such as urban violence and historical revisionism to engage in post-identity politics avoiding narratives of nation, class and gender. One of the most prominent features in these recent works is a questioning of the status of the image, which vacillates between fiction and documentary without a point of resolution. This vacillation can be understood in terms of the performative nature of films like The Monsters, The Residents, The Earth Giveth, The Earth Taketh and Avenida Brasilia Formosa. Such films are centered around improvisations that open up the image to the real. Therefore, these films produce a space between fiction and documentary, between reality and artifice that is productive and politically charged. This proposal aims at discussing this “Brand New” Brazilian Cinema (Novísssimo Cinema Brasileiro and the performative force of bodies in its affective realism. No longer a referent for a sociological truth about Brazilian society, realism is taken as something that the image does, i. e., as an affect that challenges the viewer's response-ability.

    Sleep duration has emerged as a crucial factor affecting body weight and feeding behaviour. The aim of our study was to explore the relationship among sleep duration, body composition, dietary intake, and quality of life (QoL) in obese subjects. Body composition was assessed by DXA. "Sensewear Armband" was used to evaluate sleep duration. SF-36 questionnaire was used to evaluate quality of life (QoL). A 3-day dietary record was administered. Subjects were divided into 2 groups: sleep duration > and ≤300 min/day. 137 subjects (105 women and 32 men), age: 49.8 ± 12.4 years, BMI: 38.6 ± 6.7 kg/m(2), were enrolled. Sleep duration was ≤300 min in 30.6 % of subjects. Absolute and relative fat mass (FM) (40.5 ± 9 vs. 36.5 ± 9.1 kg; 40.2 ± 4.7 vs. 36.9 ± 5.6 %), and truncal fat mass (19.2 ± 6.1 vs. 16.6 ± 5 kg; 38.6 ± 5.3 vs. 35.2 ± 5.5 %) were higher in subjects sleeping ≤300 min when compared to their counterparts (all p sleeping ≤300 min reported a higher carbohydrate consumption per day (51.8 ± 5.1 vs. 48.4 ± 9.2 %, p = 0.038). SF-36 total score was lower in subjects sleeping ≤300 min (34.2 ± 17.8 vs. 41.4 ± 12.9, p = 0.025). Sleep duration was negatively associated with FM (r = -0.25, p = 0.01) and SF-36 total score (r = -0.31, p sleep duration and SF-36 total score was confirmed by the regression analysis after adjustment for BMI and fat mass (R = 0.43, R (2) = 0.19, p = 0.012). Reduced sleep duration negatively influences body composition, macronutrient intake, and QoL in obese subjects.

    Osteoporosis is one of the complications for patients with rheumatoid arthritis (RA). Rheumatoid cachexia, the loss of lean body mass, is another. However, the relationship between decreased lean body mass and reduced bone mineral density (BMD) in patients with RA has not been well studied. This study included 413 participants, comprising 208 patients with RA and 205 age- and sex-matched healthy volunteers. Clinical data, BMD, bone metabolic markers (BMM) and body composition, such as lean body mass and percent fat, were collected. Risk factors for osteoporosis in patients with RA including the relationship BMD and body composition were analyzed. Patients with RA showed low BMD and high BMM compared with controls. Moreover, lean body mass was lower and percent fat was higher in patients with RA. Lean body mass correlated positively and percent fat negatively with BMD. Lean body mass was a positive and disease duration was a negative independent factor for BMD in multivariate statistical analysis. BMD and lean body mass were significantly lower in patients with RA compared to healthy controls. Lean body mass correlated positively with BMD and decreased lean body mass and disease duration affected low BMD in patients with RA.

    Ethanol occurs in fleshy fruit as a result of sugar fermentation by both microorganisms and the plant itself; its concentration [EtOH] increases as fruit ripens. At low concentrations, ethanol is a nutrient, whereas at high concentrations, it is toxic. We hypothesized that the effects of ethanol on the foraging behavior of frugivorous vertebrates depend on its concentration in food and the body condition of the forager. We predicted that ethanol stimulates food consumption when its concentration is similar to that found in ripe fruit, whereas [EtOH] below or above that of ripe fruit has either no effect, or else deters foragers, respectively. Moreover, we expected that the amount of food ingested on a particular day of feeding influences the toxic effects of ethanol on a forager, and consequently shapes its feeding decisions on the following day. We therefore predicted that for a food-restricted forager, ethanol-rich food is of lower value than ethanol-free food. We used Egyptian fruit bats (Rousettus aegyptiacus) as a model to test our hypotheses, and found that ethanol did not increase the value of food for the bats. High [EtOH] reduced the value of food for well-fed bats. However, for food-restricted bats, there was no difference between the value of ethanol-rich and ethanol-free food. Thus, microorganisms, via their production of ethanol, may affect the patterns of feeding of seed-dispersing frugivores. However, these patterns could be modified by the body condition of the animals because they might trade-off the costs of intoxication against the value of nutrients acquired.

    2011-03-01

    The aim of this study was to examine whether ground kinetic asymmetries significantly affected measures of bar end power output during bilateral lower-body resistance exercise. Vertical ground reaction forces (GRFs) from both feet and power outputs from both ends of the bar were recorded using force platforms and high-speed cameras simultaneously during the back squat performance of 10 experienced male volunteers with 30, 60, and 90% of their 1 repetition maximum. Side dominance was determined according to perceived left- and right-side handedness, dominant left- and right-side GRFs, and barbell power output side dominance. The dominant and nondominant side average concentric phase GRFs and barbell end power outputs were compared at each loading condition using 2-way analysis of variance. Pearson product-moment correlations were also performed to assess the relationship between average GRF and bar end differences. The results showed that although differences between the dominant and nondominant side GRFs reached 21% in some cases, there were no significant differences between the left- and right-side bar end power outputs, which did not exceed 3.4%. There were no consistent correlations between the dominant and nondominant side average GRFs and average bar end power differences. In addition to this, progressive loading did not significantly affect differences between the dominant and nondominant side GRFs or bar end power output differences. It was concluded that although apparently healthy individuals demonstrate considerable side dominance at the foot-floor interface, these tend not to be reflected in the symmetry of bar end power output.

    Changes in body fatness may impact the accuracy of dual energy X-ray absorptiometry (DXA) measures of bone mineral content (BMC) and bone mineral density (BMD). The aim of this study was to determine if DXA can accurately assess BMC and BMD with changes in exogenous fat (lard) placed to simulate weight change. Whole body (WB), lumbar spine (LS), and proximal femur (PF) DXA scans (Hologic QDR 4500A) were performed on 30 elderly (52-83 yr) and 60 young (18-40 yr) individuals (i.e., 45 females and 45 males) of varying body mass index (mean+/-standard deviation: 26.1+/-4.9 kg/m2). When scans were repeated with lard packets (2.54 cm thick, 25.4x17.8 cm, 1 kg), WB BMD decreased 1.1% and 1.6% after chest and thigh packet placement, respectively (p=0.001), PF BMD increased 0.7% (p=0.02) and LS BMD decreased 1.6% (p=0.001) primarily due to a 2.2% reduction in LS BMC (p<0.001). Initial LS BMC and trunk mass were related to error in LS BMC measures due to lard-loading (r=0.64 and 0.45, respectively, p<0.001). We conclude that on average simulated weight change minimally impacts PF bone measures and moderately impacts WB and LS bone measures; however, individual variability in measurement error was noteworthy and may be impacted by body thickness.

  2. Action during body perception: processing time affects self-other correspondences.

    The accurate perception of other people and their postures is essential for functioning in a social world. Our own bodies organize information from others to help us respond appropriately by creating self-other mappings between bodies. In this study, we investigated mechanisms involved in the processing of self-other correspondences. Reed and Farah (1995) showed that a multimodal, articulated body representation containing the spatial relations among parts of the human body was accessed by both viewing another's body and moving one's own. Use of one part of the body representation facilitated the perception of homologous areas of other people's bodies, suggesting that inputs from both the self and other activated the shared body representation. Here we investigated whether this self-other correspondence produced rapid facilitation or required additional processing time to resolve competing inputs for a shared body representation. Using a modified Reed and Farah dual-task paradigm, we found that processing time influenced body-position memory: an interaction between body-part moved and body-part attended revealed a relative facilitation effect at the 5 s ISI, but interference at the 2 s ISI. Our results suggest that effective visual-motor integration from the self and other requires time to activate shared portions of the spatial body representation.

    2015-01-01

    The theory of Participatory Discrepancies (or PDs) claims that minute temporal asynchronies (microtiming) in music performance are crucial for prompting bodily entrainment in listeners, which is a fundamental effect of the “groove” experience. Previous research has failed to find evidence to support this theory. The present study tested the influence of varying PD magnitudes on the beat-related body movement behavior of music listeners. 160 participants (79 music experts, 81 non-experts) listened to 12 music clips in either Funk or Swing style. These stimuli were based on two audio recordings (one in each style) of expert drum and bass duo performances. In one series of six clips, the PDs were downscaled from their originally performed magnitude to complete quantization in steps of 20%. In another series of six clips, the PDs were upscaled from their original magnitude to double magnitude in steps of 20%. The intensity of the listeners' beat-related head movement was measured using video-based motion capture technology and Fourier analysis. A mixed-design Four-Factor ANOVA showed that the PD manipulations had a significant effect on the expert listeners' entrainment behavior. The experts moved more when listening to stimuli with PDs that were downscaled by 60% compared to completely quantized stimuli. This finding offers partial support for PD theory: PDs of a certain magnitude do augment entrainment in listeners. But the effect was found to be small to moderately sized, and it affected music expert listeners only. PMID:26347694

    Full Text Available An estimated 230 million children live surrounded by armed conflicts, and approximately 5 million children have been forced to leave their homes for reasons connected with the ongoing conflicts worldwide. Some of these children are “only” observers of war despair or live their childhood as refugees or displaced persons; others become active participants as soldiers. Both categories are deeply sensible and vulnerable, as many negative factors can influence their psychophysical and social development. The activities of the UN main bodies (General Assembly, Security Council, Secretary-General, but also of some others, established only for the purpose to protect a child affected by armed conflict (e.g. Special Representative of the Secretary-General for Children and Armed Conflict are being known in this field since the beginning of last decade of the 20th century. However, despite earlier efforts, their more efficient cooperation and coordination in reporting and monitoring mechanism enforcement has being recognized in last ten years.

    Body image disturbances play a significant role in the development of eating disorders. Since body image can vary in diverse contexts, the aim of the present experiment was to investigate whether it is affected by recent food intake. Fifty-seven females without clinically relevant eating disorders were randomly assigned to an experimental group (EG, n=28) that consumed a milkshake while watching a neutral film and a control group (CG, n=29) that only viewed the movie. Before and after the tasks, participants filled in the "Body Image States Scale" and the "Mood Questionnaire" and indicated their own "actual", "felt" and "ideal" body dimensions with a digital distortion technique based on a photograph of themselves. It was shown that after milkshake consumption, state body dissatisfaction as well as the discrepancy between "actual-ideal" and "felt-ideal" body size estimations was higher in the EG than in the CG. Judgements of the "actual", "felt" and "ideal" body dimensions and of mood were not affected. Further analyses revealed that the effect of milkshake consumption on body image and mood was higher the more the participants displayed restrained eating or eating, weight and shape concerns in general. Clinical implications are discussed.

    Optimal levels of the thiopurine metabolite, 6-thioguanine nucleotides [6-TGN] correlate with remission of inflammatory bowel disease [IBD]. Apart from variations in the thiopurine methyl transferase [TPMT] gene, little is known about other predictors of 6-TGN levels. Obesity adversely affects response to infliximab and adalimumab and clinical course in IBD, but little is known about the interaction of thiopurines and obesity. We investigated the relationship between body mass index [BMI] and 6-TGN levels and sought to examine other predictors of 6-TGN levels. This retrospective cohort study included patients with concurrent measurements of 6-TGN and BMI. The association between 6-TGN and clinical variables including BMI was estimated using a multivariable linear regression model. Of 132 observations, 77 [58%] had Crohn's disease and 55 [42%] ulcerative colitis. BMI, smoking, and TPMT levels were associated with 6-TGN levels in multivariable analysis. Every 5kg/m(2) increase in BMI was associated with an 8% decrease in 6-TGN (0.92; 95% confidence interval [CI] 0.87-0.98; p = 0.009). Smokers had higher 6-TGN levels in comparison with non-/ex-smokers [1.43; 95% CI 1.02-2.02; p = 0.041]. Patients with intermediate TPMT had higher 6-TGN compared to those with normal levels [2.13; 95% CI 1.62-2.80; p smoking and intermediate TPMT values were associated with higher 6-TGN levels but increasing BMI resulted in lower 6-TGN and higher MMPN levels. This may explain the worse outcome that has been reported previously in obese IBD subjects. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press.

  7. Body Mass Index and Sex Affect Diverse Microbial Niches within the Gut

    Full Text Available Gut microbiota is considered a separate organ with endocrine capabilities, actively contributing to tissue homeostasis. It consists of at least two separate microbial populations, the lumen-associated (LAM and the mucosa-associated microbiota (MAM. In the present study, we compared LAM and MAM, by collecting stools and sigmoid brush samples of forty adults without large-bowel symptoms, and through a 16S rRNA gene next-generation sequencing (NGS approach. MAM sample analysis revealed enrichment in aerotolerant Proteobacteria, probably selected by a gradient of oxygen that decreases from tissue to lumen, and in Streptococcus and Clostridium spp., highly fermenting bacteria. On the other hand, LAM microbiota showed an increased abundance in Bacteroides, Prevotella, and Oscillospira, genera able to digest and to degrade biopolymers in the large intestine. Predicted metagenomic analysis showed LAM to be enriched in genes encoding enzymes mostly involved in energy extraction from carbohydrates and lipids, whereas MAM in amino acid and vitamin metabolism. Moreover, LAM and MAM communities seemed to be influenced by different host factors, such as diet and sex. LAM is affected by body mass index (BMI status. Indeed, BMI negatively correlates with Faecalibacterium prausnitzii and Flavonifractor plautii abundance, putative biomarkers of healthy status. In contrast, MAM microbial population showed a significant grouping according to sex. Female MAM was enriched in Actinobacteria (with an increased trend of the genus Bifidobacterium, and a significant depletion in Veillonellaceae. Interestingly, we found the species Gemmiger formicilis to be associated with male and Bifidobacterium adolescentis, with female MAM samples. In conclusion, our results suggest that gut harbors microbial niches that differ in both composition and host factor susceptibility, and their richness and diversity may be overlooked evaluating only fecal samples.

  8. Oral factors affecting titanium elution and corrosion: an in vitro study using simulated body fluid.

    Full Text Available OBJECTIVES: Ti, which is biocompatible and resistant to corrosion, is widely used for dental implants, particularly in patients allergic to other materials. However, numerous studies have reported on Ti allergy and the in vitro corrosion of Ti. This study investigated the conditions that promote the elution of Ti ions from Ti implants. METHODS: Specimens of commercially pure Ti, pure nickel, a magnetic alloy, and a gold alloy were tested. Each specimen was immersed in a simulated body fluid (SBF whose pH value was controlled (2.0, 3.0, 5.0, 7.4, and 9.0 using either hydrochloric or lactic acid. The parameters investigated were the following: duration of immersion, pH of the SBF, contact with a dissimilar metal, and mechanical stimulus. The amounts of Ti ions eluted were measured using a polarized Zeeman atomic absorption spectrophotometer. RESULTS: Eluted Ti ions were detected after 24 h (pH of 2.0 and 3.0 and after 48 h (pH of 9.0. However, even after 4 weeks, eluted Ti ions were not detected in SBF solutions with pH values of 5.0 and 7.4. Ti elution was affected by immersion time, pH, acid type, mechanical stimulus, and contact with a dissimilar metal. Elution of Ti ions in a Candida albicans culture medium was observed after 72 h. SIGNIFICANCE: Elution of Ti ions in the SBF was influenced by its pH and by crevice corrosion. The results of this study elucidate the conditions that lead to the elution of Ti ions in humans, which results in implant corrosion and Ti allergy.

    It has been shown that vagal nerve stimulation (VNS) can affect body mass. The aim of this study was to evaluate effect of VNS on body mass, body composition, metabolic rate, and plasma leptin and IGF-I levels. Eight female pigs were included in the study. Under general anesthesia, a bipolar electrode was implanted on the anterior vagal nerve by laparoscopy. Group A was treated by VNS, and group B was the control. After 4 weeks, stimulation was discontinued in group A and started in group B. The following parameters were evaluated: body mass, body composition, metabolic rate, plasma leptin and IGF-1 levels and intramuscular fat content (IMF). VNS attenuated body weight gain (2.28 +/- 3.47 kg vs 14.04 +/- 6.75 kg; P = .0112, for stimulation and nonstimulation periods, respectively), backfat gain (0.04 +/- 0.26 mm vs 2.31 +/- 1.12 mm) and IMF gain (-3.76 +/- 6.06 mg/g MS vs 7.24 +/- 12.90 mg/g MS; P = .0281). VNS resulted in lower backfat depth/loin muscle area ratio (0.33 +/- 0.017 vs 0.38 +/- 0.35; P = .0476). Lower plasma IGF-I concentration was found after VNS (-3.67 +/- -11.55 ng/mL vs 9.86 +/- 10.74 ng/mL; P = .0312). No significant changes in other parameters were observed. VNS affects body weight mainly at the expense of body fat resources; however, metabolic rate is not affected.

  10. Clear signals or mixed messages: inter-individual emotion congruency modulates brain activity underlying affective body perception

    2016-01-01

    The neural basis of emotion perception has mostly been investigated with single face or body stimuli. However, in daily life one may also encounter affective expressions by groups, e.g. an angry mob or an exhilarated concert crowd. In what way is brain activity modulated when several individuals express similar rather than different emotions? We investigated this question using an experimental design in which we presented two stimuli simultaneously, with same or different emotional expressions. We hypothesized that, in the case of two same-emotion stimuli, brain activity would be enhanced, while in the case of two different emotions, one emotion would interfere with the effect of the other. The results showed that the simultaneous perception of different affective body expressions leads to a deactivation of the amygdala and a reduction of cortical activity. It was revealed that the processing of fearful bodies, compared with different-emotion bodies, relied more strongly on saliency and action triggering regions in inferior parietal lobe and insula, while happy bodies drove the occipito-temporal cortex more strongly. We showed that this design could be used to uncover important differences between brain networks underlying fearful and happy emotions. The enhancement of brain activity for unambiguous affective signals expressed by several people simultaneously supports adaptive behaviour in critical situations. PMID:27025242

    , inter-individual variance in the responsiveness to DPP-4 inhibitors was reported. Thus, we asked whether genetic variation in the DPP4 gene affects incretin levels, insulin secretion, and glucose tolerance in participants of the TÜbingen Family study for type-2 diabetes (TÜF). RESEARCH DESIGN...... determined. RESULTS: We identified a variant, i.e., SNP rs6741949, in intron 2 of the DPP4 gene that, after correction for multiple comparisons and appropriate adjustment, revealed a significant genotype-body fat interaction effect on glucose-stimulated plasma GLP-1 levels (p = 0.0021). Notably, no genotype......-BMI interaction effects were detected (p = 0.8). After stratification for body fat content, the SNP negatively affected glucose-stimulated GLP-1 levels (p = 0.0229), insulin secretion (p = 0.0061), and glucose tolerance (p = 0.0208) in subjects with high body fat content only. CONCLUSIONS: A common variant, i...

  19. Spatial Cognition, Body Representation and Affective Processes: The Role of Vestibular Information beyond Ocular Reflexes and Control of Posture

    Full Text Available A growing number of studies in humans demonstrate the involvement of vestibular information in tasks that are seemingly remote from well-known functions such as space constancy or postural control. In this review article we point out three emerging streams of research highlighting the importance of vestibular input: 1 Spatial Cognition: Modulation of vestibular signals can induce specific changes in spatial cognitive tasks like mental imagery and the processing of numbers. This has been shown in studies manipulating body orientation (changing the input from the otoliths, body rotation (changing the input from the semicircular canals, in clinical findings with vestibular patients, and in studies carried out in microgravity. There is also an effect in the reverse direction; top-down processes can affect perception of vestibular stimuli. 2 Body Representation: Numerous studies demonstrate that vestibular stimulation changes the representation of body parts, and sensitivity to tactile input or pain. Thus, the vestibular system plays an integral role in multisensory coordination of body representation. 3 Affective Processes and Disorders: Studies in psychiatric patients and patients with a vestibular disorder report a high comorbidity of vestibular dysfunctions and psychiatric symptoms. Recent studies investigated the beneficial effect of vestibular stimulation on psychiatric disorders, and how vestibular input can change mood and affect. These three emerging streams of research in vestibular science are – at least in part – associated with different neuronal core mechanisms. Spatial transformations draw on parietal areas, body representation is associated with somatosensory areas, and affective processes involve insular and cingulate cortices, all of which receive vestibular input. Even though a wide range of different vestibular cortical projection areas has been ascertained, their functionality still is scarcely understood.

    Initial offspring size is a fundamental component of absolute growth rate, where large offspring will reach a given adult body size faster than smaller offspring. Yet, our knowledge regarding the coevolution between offspring and adult size is limited. In time-constrained environments, organisms need to reproduce at a high rate and reach a reproductive size quickly. To rapidly attain a large adult body size, we hypothesize that, in seasonal habitats, large species are bound to having a large initial size, and consequently, the evolution of egg size will be tightly matched to that of body size, compared to less time-limited systems. We tested this hypothesis in killifishes, and found a significantly steeper allometric relationship between egg and body sizes in annual, compared to nonannual species. We also found higher rates of evolution of egg and body size in annual compared to nonannual species. Our results suggest that time-constrained environments impose strong selection on rapidly reaching a species-specific body size, and reproduce at a high rate, which in turn imposes constraints on the evolution of egg sizes. In combination, these distinct selection pressures result in different relationships between egg and body size among species in time-constrained versus permanent habitats. © 2017 The Author(s).

    Predictors of the ketogenic diet's success in treating pediatric intractable epilepsy are not well understood. The aim of this study was to determine whether initial body mass index and weight percentile impact early efficacy of the traditional ketogenic diet in children initiating therapy for intractable epilepsy. This retrospective study included all children initiating the ketogenic diet at Mayo Clinic, Rochester from January 2001 to December 2010 who had body mass index (children ≥2 years of age) or weight percentile (those diet initiation and seizure frequency recorded at diet initiation and one month. Responders were defined as achieving a >50% seizure reduction from baseline. Our cohort consisted of 48 patients (20 male) with a median age of 3.1 years. There was no significant correlation between initial body mass index or weight percentile and seizure frequency reduction at one month (P = 0.72, r = 0.26 and P = 0.91, r = 0.03). There was no significant association between body mass index or weight percentile quartile and responder rates (P = 0.21 and P = 0.57). Children considered overweight or obese at diet initiation (body mass index or weight percentile ≥85) did not have lower responder rates than those with body mass index or weight percentiles ketogenic diet.

    Full Text Available Factors such as temperature, habitat, larval density, food availability and food quality substantially affect organismal development. In addition, risk of predation has a complex impact on the behavioural and morphological life history responses of prey. Responses to predation risk seem to be mediated by physiological stress, which is an adaptation for maintaining homeostasis and improving survivorship during life-threatening situations. We tested whether predator exposure during the larval phase of development has any influence on body elemental composition, energy reserves, body size, climbing speed and survival ability of adult Drosophila melanogaster. Fruit fly larvae were exposed to predation by jumping spiders (Phidippus apacheanus, and the percentage of carbon (C and nitrogen (N content, extracted lipids, escape response and survival were measured from predator-exposed and control adult flies. The results revealed predation as an important determinant of adult phenotype formation and survival ability. D. melanogaster reared together with spiders had a higher concentration of body N (but equal body C, a lower body mass and lipid reserves, a higher climbing speed and improved adult survival ability. The results suggest that the potential of predators to affect the development and the adult phenotype of D. melanogaster is high enough to use predators as a more natural stimulus in laboratory experiments when testing, for example, fruit fly memory and learning ability, or when comparing natural populations living under different predation pressures.

    Background Pulsed radiofrequency (RF) magnetic fields, required to produce magnetic resonance imaging (MRI) signals from tissue during the MRI procedure have been shown to heat tissues. Objectives To investigate the relationship between body temperature rise and the RF power deposited during routine clinical MRI procedures, and to determine the correlation between this effect and the body’s physiological response. Patients and Methods We investigated 69 patients from the Korean national cancer center to identify the main factors that contribute to an increase in body temperature (external factors and the body’s response) during a clinical brain MRI. A routine protocol sequence of MRI scans (1.5 T and 3.0 T) was performed. The patient’s tympanic temperature was recorded before and immediately after the MRI procedure and compared with changes in variables related to the body’s physiological response to heat. Results Our investigation of the physiological response to RF heating indicated a link between increasing age and body temperature. A higher increase in body temperature was observed in older patients after a 3.0-T MRI (r = 0.07, P = 0.29 for 1.5-T MRI; r = 0.45, P = 0.002 for 3.0-T MRI). The relationship between age and body heat was related to the heart rate (HR) and changes in HR during the MRI procedure; a higher RF power combined with a reduction in HR resulted in an increase in body temperature. Conclusion A higher magnetic field strength and a decrease in the HR resulted in an increase in body temperature during the MRI procedure. PMID:27895872

    The human body is both the physical form inhabited by an individual “self” and the medium through which an individual engages with society. Hence the body both shapes and is shaped by an individual’s social roles. In contrast to the cognate fields of archaeology, anthropology, and classics, there has been little explicit discussion or theorization of the body in Egyptology. Some recent works, discussed here, constitute an exception to this trend, but there is much more scope for exploring anc...

    Daily torpor is a physiological adaptation in mammals and birds characterized by a controlled reduction of metabolic rate and body temperature during the resting phase of circadian rhythms. In laboratory mice, daily torpor is induced by dietary caloric restriction. However, it is not known which nutrients are related to daily torpor expression. To determine whether dietary protein is a key factor in inducing daily torpor in mice, we fed mice a protein-restricted (PR) diet that included only one-quarter of the amount of protein but the same caloric level as a control (C) diet. We assigned six non-pregnant female ICR mice to each group and recorded their body weights and core body temperatures for 4 weeks. Body weights in the C group increased, but those in the PR group remained steady or decreased. Mice in both groups did not show daily torpor, but most mice in a food-restricted group (n=6) supplied with 80% of the calories given to the C group exhibited decreased body weights and frequently displayed daily torpor. This suggests that protein restriction is not a trigger of daily torpor; torpid animals can conserve their internal energy, but torpor may not play a significant role in conserving internal protein. Thus, opportunistic daily torpor in mice may function in energy conservation rather than protein saving.

  8. Sexual selection in cane toads Rhinella marina: A male’s body size affects his success and his tactics

    Full Text Available Male body size can play an important role in the mating systems of anuran amphibians. We conducted laboratory-based trials with cane toads Rhinella (Bufo marina from an invasive population in the wet-dry tropics of northern Australia, to clarify the effects of a male's body size on his reproductive success and behavior (mate choice. Males were stimulated with a synthetic hormone to induce reproductive readiness. Larger body size enhanced a male toad's ability to displace a smaller rival from amplexus, apparently because of physical strength: more force was required to dislodge a larger than a smaller amplectant male. A male’s body size also affected his mate-choice criteria. Males of all body sizes were as likely to attempt amplexus with another male as with a female of the same size, and preferred larger rather than smaller sexual targets. However, this size preference was stronger in larger males and hence, amplexus was size-assortative. This pattern broke down when males were given access to already-amplectant male-female pairs: males of all body sizes readily attempted amplexus with the pair, with no size discrimination. An amplectant pair provides a larger visual stimulus, and prolonged amplexus provides a strong cue for sex identification (one of the individuals involved is almost certainly a female. Thus, a male cane toad’s body size affects both his ability to defeat rivals in physical struggles over females, and the criteria he uses when selecting potential mates, but the impacts of that selectivity depend upon the context in which mating occurs [Current Zoology 59 (6: 747–753, 2013].

    The primary objective was to investigate whether dosing glucose by body weight results in spurious effects on measures of glucose tolerance in obese cats because volume of distribution does not increase linearly with body weight. Healthy research cats (n = 16; 6 castrated males, 10 spayed females) were used. A retrospective study was performed using glucose concentration data from glucose tolerance and insulin sensitivity tests before and after cats were fed ad libitum for 9 to 12 mo to promote weight gain. The higher dose of glucose (0.5 vs 0.3 g/kg body weight) in the glucose tolerance tests increased 2-min glucose concentrations (P glucose (r = 0.65, P = 0.006). Two-min (P = 0.016 and 0.019, respectively), and 2-h (P = 0.057 and 0.003, respectively) glucose concentrations, and glucose half-life (T1/2; P = 0.034 and Glucose dose should be decreased by 0.05 g for every kg above ideal body weight. Alternatively, for every unit of body condition score above 5 on a 9-point scale, observed 2-h glucose concentration should be adjusted down by 0.1 mmol/L. Dosing glucose based on body weight spuriously increases glucose concentrations at 2 h in obese cats and could lead to cats being incorrectly classified as having impaired glucose tolerance. This has important implications for clinical studies assessing the effect of interventions on glucose tolerance when lean and obese cats are compared. Copyright © 2016 Elsevier Inc.

    Since waterborne minerals appear in ionic form and are readily absorbed by the gastrointestinal tract, drinking water could be a crucial source of mineral intake. However, no comprehensive research has yet determined how trace elements in drinking water relate to body composition. We aimed to assess the relationship between clinically important trace elements in public drinking water and body composition in average, overweight and obese individuals in Turkey. The study's population consisted of 423 participants: 143 overweight, 138 obese and 142 healthy control individuals, grouped according to clinical cutoff points of body mass index (BMI). We measured levels of lithium (Li), nickel (Ni), lead (Pb), silicon (Si), tin (Sn), strontium (Sr), boron (B), aluminium (Al), barium (Ba) and rubidium (Rb) in samples from wells of municipal water by using inductively coupled plasma mass spectrometry. We gauged all the participants' body composition measurements with a BC-418 body composition analyser. In all the participants, body weight values showed significant positive correlations with Ni levels in drinking water, as did BMI values with Al levels and percentage of obesity with Ni, Si and B levels. In particular, Ni levels showed significant positive correlations with the basal metabolic rate, activity calories, and total activity of participants. Giving findings showing correlations between obesity-related parameters and Al, Si, B and Ni content in drinking water, we hope that these associations will be clarified with further studies including cellular, experimental and clinical studies. Hence, medical practitioners must be aware of trace element levels in drinking water for overweight and obese patients.

    We report the results of a preliminary study testing the effect of participants' mood rating on visual motor performance using a haptic device to manipulate a cartoonish human body. Our results suggest that moods involving high arousal (e.g. happiness) produce larger movements whereas mood involving low arousal (e.g. sadness) produce slower speed of performance. Our results are used for the development of a new haptic virtual reality application that we briefly present here. This application is intended to create a more interactive and motivational environment to treat body image issues and for emotional communication.

    To evaluate the influence of self-esteem on levels of body dissatisfaction among adolescent females. A group of 397 adolescents aged 12 to 17 years were enrolled in the study. The Body Shape Questionnaire (BSQ) was applied to assess body dissatisfaction. The Rosenberg Self-Esteem Scale was used to assess self-esteem. Weight, height, and skinfold thickness were also measured. These anthropometric data were controlled in the statistical analyses. The multiple regression model indicated influence of "positive self-esteem" (R(2)=0.16; p=0.001) and "negative self-esteem" (R(2)=0.23; p=0.001) subscales on the BSQ scores. Univariate analysis of covariance demonstrated differences in BSQ scores (p=0.001) according to groups of self-esteem. It was concluded that self-esteem influenced body dissatisfaction in adolescent girls from Juiz de Fora, MG. Copyright © 2014 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    Full Text Available The objective of this research was to determine the effect of breed, feed type and sex, on the final body weight in New Zealand white and Blanc de Termonde rabbits. The experiment was conducted on a farm in the Małopolska Province in the south of Poland. Rabbits of both breeds were kept in identical conditions up to the age of 90 days. However, they were fed using two different methods – with commercial balanced (granulated feed (9.75 MJ, 155 g protein and farm-made feed (9.54 MJ, 157 g protein. Among New Zealand White rabbits, commercial balanced feed was given to 38 males and 42 females, whereas farm-made feed to 37 males and 38 females. Among Blanc de Termonde rabbits, commercial balanced feed was given to 65 males and 68 females, and farm-made feed to 54 males and 60 females. Daily gains were determined for both examined breeds divided into sexes. Then, we calculated interactions between breed and feed type, between breed and sex, as well as between feed type and sex. The mean body weights on the 90th day of fattening differed for both sexes and feed types. For both rabbit breeds, the higher mean final body weight was observed in case of feeding with the commercial balanced feed, whereas the highest body weight (2515.13 g was registered for the females of Blanc de Termonde rabbits.

    To investigate the possible effects of dietary, patient and stone related factors on the clinical course of the stone disease as well as the body and renal growth status of the infants. A total of 50 children with an history of stone disease during infancy period were studied. Patient (anatomical abnormalities, urinary tract infection - UTI, associated morbidities), stone (obstruction, UTI and required interventions) and lastly dietary (duration of sole breast feeding, formula feeding) related factors which may affect the clinical course of the disease were all evaluated for their effects on the body and renal growth during long-term follow-up. Mean age of the children was 2.40 ± 2.65 years. Our findings demonstrated that infants receiving longer period of breast feeding without formula addition seemed to have a higher rate of normal growth percentile values when compared with the other children. Again, higher frequency of UTI and stone attacks affected the growth status of the infants in a remarkable manner than the other cases. Our findings also demonstrated that thorough a close follow-up and appropriately taken measures; the possible growth retardation as well as renal growth problems could be avoided in children beginning to suffer from stone disease during infancy period. Duration of breast feeding, frequency of UTI, number of stone attacks and stone removal procedures are crucial factors for the clinical course of stone disease in infants that may affect the body as well as kidney growth during long-term follow-up.

    Thorium workers with thorium body burdens (primarily thoracic) above 0.7 nCi 224 Ra equivalent are shown to exhale about 15% of thoron produced in vivo, compared to 5% exhaled by subjects with body burdens in the range of 0.4 to 0.7 nCi 224 Ra. There was a false negative correlation between average adult daily cigarettes smoked and thoron exhalation. White blood cell counts that were about 85% of expected were observed in seven subjects exhaling greater than or equal to 100 pCi of thoron above predicted; no other variable examined showed a clear pattern of association. These differences in fractional thoron exhalation, and their consequences, are discussed. 3 references, 4 figures, 8 tables

    Full Text Available We examined 24 maternal half-sib families of gilthead seabream to identify quantitative trait loci (QTL associated with body weight at four time points during a production cycle. 57 brooders and 637 offspring were genotyped for 14 informative microsatellite markers, spanning linkage groups 1 and 21. The QTL detection method was based on half-sib interval mapping analysis through a linear regression approach. One QTL was found significant at all time points in linkage group 1, with its effect having different profile across time, and one QTL in linkage group 21 that seems to impact body weight at a later growth stage of the species. Current results verified previously published QTL for growth in the above linkage groups, using a different genetic background of seabream. These QTL can be considered as valuable candidates for use in marker-assisted selective breeding programs, aiming at high rates of genetic improvement for growth in S. aurata.

    The evacuation and disruption in housing caused by the 2011 Great East Japan Earthquake and following nuclear radiation may have influenced child health in many respects. However, studies regarding longitudinal childhood growth are limited. Therefore, in this study we aimed to explore the influence of the earthquake on longitudinal changes in body mass index in preschool children. Participants were children from nursery schools who cooperated with the study in the Iwate, Miyagi and Fukushima prefectures. The exposed group consisted of children who experienced the earthquake during their preschool-age period (4-5 years old). The historical control group included children who were born 2 years earlier than the exposed children in the same prefectures. Trajectories regarding body mass index and prevalence of overweight/obesity were compared between the two groups using multilevel analysis. Differences in the changes in BMI between before and after the earthquake, and proportion of overweight/obesity was compared between the two groups. We also conducted subgroup analysis by defining children with specific personal disaster experiences within the exposed group. A total of 9722 children were included in the study. Children in the exposed group had higher body mass indices and a higher proportion of overweight after the earthquake than the control group. These differences were more obvious when confined to exposed children with specific personal disaster experiences. Children's growth and development-related health issues such as increased BMI after natural disasters should evoke great attention.

    Data were collected prospectively on parameters related to first calving on 18 farms located in Northeastern Pennsylvania. This project was designed to study possible residual effects of calf management practices and events occurring during the first 16 wk of life on age, BW, skeletal growth, and body condition score at first calving. Multiple imputation method for handling missing data was incorporated in these analyses. This method has the advantage over ad hoc single imputations because the appropriate error structure is maintained. Much similarity was found between the multiple imputation method and a traditional mixed model analysis, except that some estimates from the multiple imputation method seemed more logical in their effects on the parameter measured. Factors related to increased age at first calving were increased difficulty of delivery, antibiotic treatment of sick calves, increased amount of milk or milk replacer fed before weaning, reduced quality of forage fed to weaned calves, maximum humidity, mean daily temperature, and maximum ammonia levels in calf housing areas. Body weight at calving tended to increase with parity of the dam, increased amount of grain fed to calves, increased ammonia levels, and increased mean temperature of the calf housing area. Body condition score at calving tended to be positively influenced by delivery score at first calving, dam parity, and milk or milk replacer dry matter intake. Withers height at calving was positively affected by treatment of animals with antibiotics and increased mean temperature in the calf area. This study demonstrated that nutrition, housing, and management factors that affect health and growth of calves have long-term effects on the animal at least through first calving.

  10. Mortality affects adaptive allocation to growth and reproduction: field evidence from a guild of body snatchers.

    The probability of being killed by external factors (extrinsic mortality) should influence how individuals allocate limited resources to the competing processes of growth and reproduction. Increased extrinsic mortality should select for decreased allocation to growth and for increased reproductive effort. This study presents perhaps the first clear cross-species test of this hypothesis, capitalizing on the unique properties offered by a diverse guild of parasitic castrators (body snatchers). I quantify growth, reproductive effort, and expected extrinsic mortality for several species that, despite being different species, use the same species' phenotype for growth and survival. These are eight trematode parasitic castrators-the individuals of which infect and take over the bodies of the same host species-and their uninfected host, the California horn snail. As predicted, across species, growth decreased with increased extrinsic mortality, while reproductive effort increased with increased extrinsic mortality. The trematode parasitic castrator species (operating stolen host bodies) that were more likely to be killed by dominant species allocated less to growth and relatively more to current reproduction than did species with greater life expectancies. Both genders of uninfected snails fit into the patterns observed for the parasitic castrator species, allocating as much to growth and to current reproduction as expected given their probability of reproductive death (castration by trematode parasites). Additionally, species differences appeared to represent species-specific adaptations, not general plastic responses to local mortality risk. Broadly, this research illustrates that parasitic castrator guilds can allow unique comparative tests discerning the forces promoting adaptive evolution. The specific findings of this study support the hypothesis that extrinsic mortality influences species differences in growth and reproduction.

    Beneficial health properties of garlic, as well as its most common adverse effect - distinctive breath odour - are well-known. In contrast, analogous research on the effect of garlic on axillary odour is currently missing. Here, in three studies varying in the amount and nature of garlic provided (raw garlic in study 1 and 2, garlic capsules in study 3), we tested the effect of garlic consumption on the quality of axillary odour. A balanced within-subject experimental design was used. In total, 42 male odour donors were allocated to either a "garlic" or "non-garlic" condition, after which they wore axillary pads for 12 h to collect body odour. One week later, the conditions were reversed. Odour samples were then judged for their pleasantness, attractiveness, masculinity and intensity by 82 women. We found no significant differences in ratings of any characteristics in study 1. However, the odour of donors after an increased garlic dosage was assessed as significantly more pleasant, attractive and less intense (study 2), and more attractive and less intense in study 3. Our results indicate that garlic consumption may have positive effects on perceived body odour hedonicity, perhaps due to its health effects (e.g., antioxidant properties, antimicrobial activity).

    We investigated the effects of adding heavy strength training to a high volume of endurance training on performance and related physiological determinants in junior female cross-country skiers. Sixteen well-trained athletes (17 ± 1 years, 60 ± 6 kg, 169 ± 6 cm, VO2max running: 60 ± 5 mL/kg/min) were assigned either to an intervention group (INT; n = 9) or a control group (CON; n = 7). INT completed two weekly sessions of upper body heavy strength training in a linear periodized fashion for 10 weeks. Both groups continued their normal aerobic endurance and muscular endurance training. One repetition maximum in seated pull-down increased significantly more in INT than in CON, with a group difference of 15 ± 8% (P training increased upper body strength but had trivial effects on performance in a double poling ergometer in junior female cross-country skiers. © 2015 John Wiley & Sons A/S.

    Full Text Available BACKGROUND: In addition to lowering cholesterol, statins are thought to beneficially modulate inflammation. Several chemokines including CXCL1/growth-related oncogene (GRO-α, CXCL8/interleukin (IL-8 and CCL2/monocyte chemoattractant protein (MCP-1 are important in the pathogenesis of atherosclerosis and can be influenced by statin-treatment. Recently, we observed that atorvastatin-treatment alters the intracellular content and subcellular distribution of GRO-α in cultured human umbilical vein endothelial cells (HUVECs. The objective of this study was to investigate the mechanisms involved in this phenomenon. METHODOLOGY/ PRINCIPAL FINDINGS: The effect of atorvastatin on secretion levels and subcellular distribution of GRO-α, IL-8 and MCP-1 in HUVECs activated by interleukin (IL-1β were evaluated by ELISA, confocal microscopy and immunoelectron microscopy. Atorvastatin increased the intracellular contents of GRO-α, IL-8, and MCP-1 and induced colocalization with E-selectin in multivesicular bodies. This effect was prevented by adding the isoprenylation substrate GGPP, but not the cholesterol precursor squalene, indicating that atorvastatin exerts these effects by inhibiting isoprenylation rather than depleting the cells of cholesterol. CONCLUSIONS/ SIGNIFICANCE: Atorvastatin targets inflammatory chemokines to the endocytic pathway and multivesicular bodies and may contribute to explain the anti-inflammatory effect of statins at the level of endothelial cell function.

    Stimulation of Type II taste receptor cells (TRCs) with T1R taste receptors causes sweet or umami taste, whereas T2Rs elicit bitter taste. Type II TRCs contain the calcium channel, calcium homeostasis modulator protein 1 (CALHM1), which releases adenosine triphosphate (ATP) transmitter to taste fibers. We have previously demonstrated with chorda tympani nerve recordings and two-bottle preference (TBP) tests that mice with genetically deleted Calhm1 (knockout [KO]) have severely impaired perception of sweet, bitter, and umami compounds, whereas their sour and salty tasting ability is unaltered. Here, we present data from KO mice of effects on glossopharyngeal (NG) nerve responses, TBP, food intake, body weight, and life span. KO mice have no NG response to sweet and a suppressed response to bitter compared with control (wild-type [WT]) mice. KO mice showed some NG response to umami, suggesting that umami taste involves both CALHM1- and non-CALHM1-modulated signals. NG responses to sour and salty were not significantly different between KO and WT mice. Behavioral data conformed in general with the NG data. Adult KO mice consumed less food, weighed significantly less, and lived almost a year longer than WT mice. Taken together, these data demonstrate that sweet taste majorly influences food intake, body weight, and life span. © The Author 2015. Published by Oxford University Press. All rights reserved.

    This study investigated the effects of two parental socio-economic characteristics, education and income, on growth and risk of obesity in children from birth to 8 years of age. Longitudinal growth data and national register-based information on socio-economic characteristics were available for 3,030 Swedish children. The development of body mass index (BMI) and height was compared in groups dichotomised by parental education and income. Low parental education was associated with a higher BMI from 4 years of age, independent of income, immigrant background, maternal BMI and smoking during pregnancy. Low family income was associated with a lower birthweight, but did not independently predict BMI development. At 8 years of age, children from less educated families had a three times higher risk of obesity, independent of parental income. Children whose parents had fewer years of education but high income had significantly higher height than all other children. Parental education protected against childhood obesity, even after adjusting for income and other important parental characteristics. Income-related differences in height, despite similar BMIs, raise questions about body composition and metabolic risk profiles. The dominant role of education underscores the value of health literacy initiatives for the parents of young children. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

  16. Dietary Resveratrol Does Not Affect Life Span, Body Composition, Stress Response, and Longevity-Related Gene Expression in Drosophila melanogaster

    Full Text Available In this study, we tested the effect of the stilbene resveratrol on life span, body composition, locomotor activity, stress response, and the expression of genes encoding proteins centrally involved in ageing pathways in the model organism Drosophila melanogaster. Male and female w1118 D. melanogaster were fed diets based on sucrose, corn meal, and yeast. Flies either received a control diet or a diet supplemented with 500 µmol/L resveratrol. Dietary resveratrol did not affect mean, median, and maximal life span of male and female flies. Furthermore, body composition remained largely unchanged following the resveratrol supplementation. Locomotor activity, as determined by the climbing index, was not significantly different between control and resveratrol-supplemented flies. Resveratrol-fed flies did not exhibit an improved stress response towards hydrogen peroxide as compared to controls. Resveratrol did not change mRNA steady levels of antioxidant (catalase, glutathione-S-transferase, NADH dehydrogenase, glutathione peroxidase, superoxide dismutase 2 and longevity-related genes, including sirtuin 2, spargel, and I’m Not Dead Yet. Collectively, present data suggest that resveratrol does not affect life span, body composition, locomotor activity, stress response, and longevity-associated gene expression in w1118 D. melanogaster.

    Artificial light at night (ALAN), termed light pollution, is an increasingly important anthropogenic environmental pressure on wildlife. Exposure to unnatural lighting environments may have profound effects on animal physiology, particularly during early life. Here, we experimentally investigated for the first time the impact of ALAN on body mass and oxidative status during development, using nestlings of a free-living songbird, the great tit (Parus major), an important model species. Body mass and blood oxidative status were determined at baseline (=13 days after hatching) and again after a two night exposure to ALAN. Because it is very difficult to generalise the oxidative status from one or two measures we relied on a multi-biomarker approach. We determined multiple metrics of both antioxidant defences and oxidative damage: molecular antioxidants GSH, GSSG; antioxidant enzymes GPX, SOD, CAT; total non-enzymatic antioxidant capacity and damage markers protein carbonyls and TBARS. Light exposed nestlings showed no increase in body mass, in contrast to unexposed individuals. None of the metrics of oxidative status were affected. Nonetheless, our study provides experimental field evidence that ALAN may negatively affect free-living nestlings’ development and hence may have adverse consequences lasting throughout adulthood.

    Positron emission tomography (PET) using 2-deoxy-2-[{sup 18}F]-fluoro-D-glucose (FDG) is very useful for the detection and staging of tumors. However, FDG is also accumulated in the normal tissues in various degrees. This physiological FDG uptake is often seen in intestine, making confusion with malignant tumor. The aim of this study was to identify factors influencing physiological FDG uptake in the stomach. A total of 136 people who underwent cancer screening or staging of tumors except for gastric cancer using FDG whole-body PET was examined (mean age: 55.6 yrs). All subjects fasted for at least 4 hours before the PET study and were administrated with FDG intravenously (mean FDG dose: 308.9 MBq). Emission images were acquired on a whole-body PET scanner and images were reconstructed without attenuation correction. The intensity of gastric uptake of FDG whole-body PET image was visually classified into 3 grades; grade 2 = the intensity of gastric uptake more than pulmonary uptake, grade 1 = the intensity of gastric uptake equal to or less than pulmonary uptake, grade 0 = no contrast between gastric uptake and background. Twenty-eight subjects (20.6%) were classified into grade 2, 42 subjects (30.9%) were grade 1 and 66 subjects (48.5%) were grade 0. Subjects' age, fasting time, FDG dose, serum glucose level, free fatty acid level and insulin level were not significantly correlated with the intensity of gastric uptake. But the subjects with higher gastric uptake tended to have anti-Helicobactor pylori (H. pylori) antibodies. The rate of having anti-H.pylori antibodies in the grade 2 group is significantly higher than the grade 1 group (85.7% vs. 72.5%, p<0.05), and that of the grade 1 group is significantly higher than the grade 0 group (72.5% vs. 42.2%, p<0.01). Gastric uptake was observed in about half of subjects. Especially, approximately 20% of all showed high gastric uptake, which was associated with H.pylori infection. Therefore, most of the subjects

    This cross-sectional analysis evaluated the effect of age and body mass index (BMI) on Three-Factor Eating Questionnaire scores in males. Subjects (n = 60) were recruited according to BMI status. Each completed the 51-item Three-Factor Eating Questionnaire. The group was split at the median age to produce a "younger" and "older" group for statistical analysis. A 2-way between-groups analysis of variance revealed a significant main effect of BMI on disinhibition (P = .003) and hunger (P = .041) with higher levels found in overweight males compared to healthy-weight counterparts. A significant main effect of age on hunger (P = .046) demonstrated older males were less susceptible to hunger than younger males. These insights provide a better understanding of eating behavior across the male life cycle and may assist health professionals to better guide men in weight management in the light of rising overweight/obesity.

    Obesity has become a public health problem and is a cause of some preventable illnesses. Among several methods for treating obesity, the use of food supplements is highly common. A commonly used food supplement is green coffee bean extract. The objective of this study was to evaluate the efficacy of green coffee bean extract combined with an energy-restricted diet on the body composition and serum adipocytokines in obese women. In this randomised clinical trial, 64 obese women aged 20-45 years were selected and divided into two groups: an intervention group (receiving 400 mg green coffee bean extract for 8 weeks) and control group (receiving placebo). All participants were on an energy-restricted diet. The body composition, leptin, adiponectin, lipid profile, free fatty acids (FFAs), and fasting blood sugar were compared between the two groups. We observed significant reductions in the body weight, body mass and fat mass indices, and waist-to-hip circumference ratio in both groups; however, the decrease was higher in the intervention group. Moreover, serum total cholesterol, low-density lipoprotein, leptin, and plasma free fatty acids significantly decreased in the intervention group (pintake. The serum adiponectin concentration significantly increased in the intervention group (p<0.05). Green coffee bean extract combined with an energy-restricted diet affects fat accumulation and lipid metabolism and is thus an inexpensive method for weight control in obese people.

    Full Text Available The objective of the investigation was to identify the geological factors affecting the spatial continuity of the flow during the process of flank water injection in the units operating in the Lower Lagunilla Hydrocarbon Ore Body. This included the evaluation of the recovery factor, the petro-physic properties such as porosity, permeability, water saturation and rock type and quality in each flow unit. it was observed that the rock type of the geologic structure in the ore body is variable. The lowest values for the petro-physic properties were found in the southern area while a high variability of these parameters was observed in the northern and central areas. It was concluded that the northern area has a great potential for the development of new injection projects for petroleum recovery.

    Body dysmorphic disorder (BDD) is characterised by repetitive behaviours and/or mental acts occurring in response to preoccupations with perceived defects or flaws in physical appearance (American Psychiatric Association, 2013). This study aimed to investigate facial affect recognition in BDD using an integrated eye-tracking paradigm. Participants were 21 BDD patients, 19 obsessive-compulsive disorder (OCD) patients and 21 healthy controls (HC), who were age-, sex-, and IQ-matched. Stimuli were from the Pictures of Facial Affect (Ekman & Friesen, 1975), and outcome measures were affect recognition accuracy as well as spatial and temporal scanpath parameters. Relative to OCD and HC groups, BDD patients demonstrated significantly poorer facial affect perception and an angry recognition bias. An atypical scanning strategy encompassing significantly more blinks, fewer fixations of extended mean durations, higher mean saccade amplitudes, and less visual attention devoted to salient facial features was found. Patients with BDD were substantially impaired in the scanning of faces, and unable to extract affect-related information, likely indicating deficits in basic perceptual operations.

    Low levels of heterozygosity can have detrimental effects on life history and growth characteristics of organisms but more subtle effects such as those on trade-offs of expensive tissues and morphological laterality, especially of the brain, have not been explicitly tested. The objective of the current study was to investigate how estimated differences in heterozygosity may potentially affect brain-to-body trade-offs and to explore how these heterozygosity differences may affect differential brain growth, focusing on directional asymmetry in adult Chinook salmon (Oncorhynchus tshawytscha) using the laterality and absolute laterality indices. Level of inbreeding was estimated as mean microsatellite heterozygosity resulting in four ‘inbreeding level groups’ (Very High, High, Medium, Low). A higher inbreeding level corresponded with a decreased brain-to-body ratio, thus a decrease in investment in brain tissue, and also showed a decrease in the laterality index for the cerebellum, where the left hemisphere was larger than the right across all groups. These results begin to show the role that differences in heterozygosity may play in differential tissue investment and in morphological laterality, and may be useful in two ways. Firstly, the results may be valuable for restocking programmes that wish to emphasize brain or body growth when crossing adults to generate individuals for release, as we show that genetic variation does affect these trade-offs. Secondly, this study is one of the first examinations to test the hypothesized relationship between genetic variation and laterality, finding that in Chinook salmon there is potential for an effect of inbreeding on lateralized morphology, but not in the expected direction.

    Full Text Available Objective: To investigate the possible effects of dietary, patient and stone related factors on the clinical course of the stone disease as well as the body and renal growth status of the infants. Patients and Methods: A total of 50 children with an history of stone disease during infancy period were studied. Patient (anatomical abnormalities, urinary tract infection - UTI, associated morbidities, stone (obstruction, UTI and required interventions and lastly dietary (duration of sole breast feeding, formula feeding related factors which may affect the clinical course of the disease were all evaluated for their effects on the body and renal growth during long-term follow-up. Results: Mean age of the children was 2.40 ± 2.65 years. Our findings demonstrated that infants receiving longer period of breast feeding without formula addition seemed to have a higher rate of normal growth percentile values when compared with the other children. Again, higher frequency of UTI and stone attacks affected the growth status of the infants in a remarkable manner than the other cases. Our findings also demonstrated that thorough a close follow-up and appropriately taken measures; the possible growth retardation as well as renal growth problems could be avoided in children beginning to suffer from stone disease during infancy period. Conclusions: Duration of breast feeding, frequency of UTI, number of stone attacks and stone removal procedures are crucial factors for the clinical course of stone disease in infants that may affect the body as well as kidney growth during long-term follow-up.

  6. How body mass and lifestyle affect juvenile biomass production in placental mammals.

    2014-02-22

    In mammals, the mass-specific rate of biomass production during gestation and lactation, here called maternal productivity, has been shown to vary with body size and lifestyle. Metabolic theory predicts that post-weaning growth of offspring, here termed juvenile productivity, should be higher than maternal productivity, and juveniles of smaller species should be more productive than those of larger species. Furthermore because juveniles generally have similar lifestyles to their mothers, across species juvenile and maternal productivities should be correlated. We evaluated these predictions with data from 270 species of placental mammals in 14 taxonomic/lifestyle groups. All three predictions were supported. Lagomorphs, perissodactyls and artiodactyls were very productive both as juveniles and as mothers as expected from the abundance and reliability of their foods. Primates and bats were unproductive as juveniles and as mothers, as expected as an indirect consequence of their low predation risk and consequent low mortality. Our results point the way to a mechanistic explanation for the suite of correlated life-history traits that has been called the slow-fast continuum.

  7. Meal patterns and frequencies: do they affect body weight in children and adolescents?

    2010-02-01

    Some previous studies reported a higher meal frequency associated with a lower body weight both in obese and in normal weight adults. We review recent studies addressing the relation between meal frequency and obesity risk in children and adolescents. In a Medline search, we identified 5 observational studies published between 2004 and 2009 that reviewed data on a total of 13,998 children and adolescents from the United States, Germany, and Portugal. Three of the five studies found a significant reduction of obesity risk with increasing number of meals, which persisted after adjustment for confounders, while the two other studies found a non-significant trend in the same direction. Given the consistent association of skipping meals with an increased obesity risk in children, it appears prudent to promote a regular meal pattern with 5 meals per day with adequate composition to children and their families. Prospective controlled trials to assess the protective potential of promoting regular and frequent meals in children and their families are highly desirable to strengthen the evidence base for such preventive approaches, which should explore the feasibility and effects of interventions.

    Outbreaks of Trichophyton tonsurans infection constitute one of the serious problems among combat sports practitioners in Japan. To facilitate the diagnosis of individuals at risk, we undertook a study to determine which body sites are most commonly infected. We reviewed medical data, hairbrush culture results and questionnaire information from patients with T. tonsurans infection who were admitted to the dermatology clinic of Juntendo University hospital from 2000 to 2004. The study included 92 patients (87 males), aged 6-38 years (mean age: 18.4 years old). Eighty-nine patients were judo practitioners and three were wrestlers. Twenty-eight patients (30.4%) were asymptomatic carriers. In 64 patients, 51 patients (55.4%) with tinea corporis, 27 patients (29.3%) with tinea capitis, and/or one patient (1.1%) with tinea manuum were seen. Tinea corporis was observed on the forehead, auricles, nape of the neck, bilateral shoulders, left side of the upper chest, both elbows, back of the left hand to the wrist and both knees. Tinea capitis was most common in the occipitonuchal region at the hairline and in the temporal and frontal regions, at both auricles. Initial screening of these sites might facilitate the identification of the infection especially in judo practitioners. © 2008 The Authors. Journal compilation © 2008 Blackwell Publishing Ltd.

    Full Text Available Aquatic sports keep rising in popularity. Kitesurfing is a high-risk sport that combines aspects of several water sports. The dangers of high-risk sports have been widely studied. Kitesurfing is a relatively new water sport, and the understanding of the injuries due to its practice has not yet been largely investigated. The purpose of this study is to investigate the most common types and causes of injuries among Portuguese kitesurfers. The data was collected using a retrospective 12 months web-based questionnaire. A total of n= 87 kitesurfers, mostly from the North, showed that 75.9% have a kitesurfing initiation course and 57.5% use protective equipment. A total of 60.9% has been injured in the 12 month’s period, being the knee and the lumbar spine the most common body injury. A reasonable number of injuries occurred while performing a landing or a maneuver, being 53.9% of the injuries reported as a new injury. This 12 month’s retrospective study supports earlier studies and provides basis knowledge about the incidence of Portuguese kitesurfers injuries. The data support the benefits of physical fitness (p< 0.05 in injuries prevention.

  10. Psychogenic fever: how psychological stress affects body temperature in the clinical population

    Psychogenic fever is a stress-related, psychosomatic disease especially seen in young women. Some patients develop extremely high core body temperature (Tc) (up to 41°C) when they are exposed to emotional events, whereas others show persistent low-grade high Tc (37–38°C) during situations of chronic stress. The mechanism for psychogenic fever is not yet fully understood. However, clinical case reports demonstrate that psychogenic fever is not attenuated by antipyretic drugs, but by psychotropic drugs that display anxiolytic and sedative properties, or by resolving patients' difficulties via natural means or psychotherapy. Animal studies have demonstrated that psychological stress increases Tc via mechanisms distinct from infectious fever (which requires proinflammatory mediators) and that the sympathetic nervous system, particularly β3-adrenoceptor-mediated non-shivering thermogenesis in brown adipose tissue, plays an important role in the development of psychological stress-induced hyperthermia. Acute psychological stress induces a transient, monophasic increase in Tc. In contrast, repeated stress induces anticipatory hyperthermia, reduces diurnal changes in Tc, or slightly increases Tc throughout the day. Chronically stressed animals also display an enhanced hyperthermic response to a novel stress, while past fearful experiences induce conditioned hyperthermia to the fear context. The high Tc that psychogenic fever patients develop may be a complex of these diverse kinds of hyperthermic responses. PMID:27227051

    The study examined differential effects of preoperative biomarkers (cotisol, C-reactive protein/CRP, and interleukin-6/IL-6) on postoperative symptoms in mental health (depressed mood, anxiety and hostility) 1 month following open-heart surgery, controlling for known predictors. Preoperative and postoperative interviews were conducted on 162 patients. Peripheral venous blood samples were collected between 8 and 10 a.m. prior to surgery. Cardiac indices were obtained from the Society of Thoracic Surgeons' national database. Preoperative anxiety contributed to all outcomes about 1 month postoperatively. Patients with high preoperative plasma IL-6 used more avoidant coping and experienced greater depressed mood. Patients with increased plasma CRP and with hope were less depressed. Elevated plasma cortisol predicted hostility. Finally, medical comorbidities predicted anxiety and hostility. The combination of anxiety and stress-sensitive biomarkers may be one way to predict postoperative symptoms following open-heart surgery. Our findings emphasize the importance of investigating the mind-body interplay to come up with better interventions.

    Full Text Available During adolescence, there is a tendency to sleep late andsleep less because of altered psychosocial and life-stylechanges. Recent studies have demonstrated the link betweensleeping less and gaining weight in children, adolescents, andadults. We studied the effect of late sleeping and sleepingless on body mass index (BMI in medical college freshmen.All participants were adolescents (104 male and 38 femaleadolescents, mean age 17.77±0.79 years. After obtaininginformed consent, they filled out a questionnaire about theirsleeping habits. Height and weight were measured after abrief history taking and clinical examination. BMI increasedsignificantly with decrease in total sleep duration and withdelayed bedtime. Late sleeping individuals (after midnighthad significantly less sleep duration (6.78 hours v 7.74 hours,P<0.001, more day time sleepiness (85.2% v 69.3%,P=0.033 and more gap between dinner time and going tosleep (234.16 min v 155.45 min, P<0.001. Increased BMI inlate sleepers may be explained by low physical activity duringthe day caused by excess sleepiness and increased calorieintake with a gap of 5-6 hours between dinner and sleep.Sleep habits of late sleeping and sleeping less contribute toincrease BMI in adolescents.

    Nup98 is an important component of the nuclear pore complex (NPC) and also a rare but recurrent target for chromosomal translocation in leukaemogenesis. Nup98 contains multiple cohesive Gly-Leu-Phe-Gly (GLFG) repeats that are critical notably for the formation of intranuclear GLFG bodies. Previous studies have reported the existence of GLFG bodies in cells overexpressing exogenous Nup98 or in a HeLa subline (HeLa-C) expressing an unusual elevated amount of endogenous Nup98. Here, we have analysed the presence of Nup98-containing bodies in several human cell lines. We found that HEp-2, another HeLa subline, contains GLFG bodies that are distinct from those identified in HeLa-C. Rapid amplification of cDNA ends (RACE) revealed that HEp-2 cells express additional truncated forms of Nup98 fused to a non-coding region of chromosome 11q22.1. Cytogenetic analyses using FISH and array-CGH further revealed chromosomal rearrangements that were distinct from those observed in leukaemic cells. Indeed, HEp-2 cells feature a massive amplification of juxtaposed NUP98 and 11q22.1 loci on a chromosome marker derived from chromosome 3. Unexpectedly, minor co-amplifications of NUP98 and 11q22.1 loci were also observed in other HeLa sublines, but on rearranged chromosomes 11. Altogether, this study reveals that distinct genomic rearrangements affecting NUP98 are associated with the formation of GLFG bodies in specific HeLa sublines.

    During attacks of vestibular neuritis (VN), patients typically lose postural balance, with resultant postural inclination, gait deviation toward the lesion side, and tendency to fall. In this study, we examined and analyzed static and dynamic postural control during attacks of VN to characterize differences in postural control between right and left VN. Subjects were patients diagnosed with VN at the Department of Otolaryngology, Toho University Sakura Medical Center, and underwent in-patient treatment. Twenty-five patients who had spontaneous nystagmus were assessed within 3days after the onset; all were right-foot dominant. Right VN was detected in nine patients (men: 4, women: 5; mean age: 57.6±17.08years [range: 23-82]) and left VN in 16 patients (men: 10, women: 6; mean age: 58.4±14.08years [range: 23-85 years]); the percentages of canal paresis of right and left VN were 86.88±18.1% and 86.02±15.0%, respectively. Statistical comparisons were conducted using the independent t-test. In stabilometry, with eyes opened, no significant differences were found between patients with right and left VN. However, with eyes closed, the center of horizontal movement significantly shifted ipsilateral (p<0.01). The differences in the lateral and anteroposterior body tracking test (BTT) were statistically significant (p=0.0039 and p=0.0376, respectively), with greater changes in cases with right VN. Thus, the dominant foot might contribute to the postural control mechanism. Copyright © 2017 Elsevier B.V. All rights reserved.

    Obese patients are highly prevalent in the pediatric orthopaedic surgeon's practice and obesity is an increasing issue in the United States. Increased body mass index (BMI) has been associated with increased complications in pediatric orthopaedic patients, but no study has looked specifically at external fixation. The purpose of this study was to determine whether obesity is a risk factor for increased complications in lower-extremity procedures requiring external fixation. A retrospective chart review was conducted of pediatric patients who underwent external fixation as definitive operative treatment for any condition at a tertiary care hospital over a 15-year period. Patients were grouped into normal weight, overweight, and obese based on Centers for Disease Control definitions. All orthopaedic complications were recorded. A total of 208 patients with a mean age of 11.2 years were identified. Ninety-four children were obese at the 95th percentile BMI or higher, 22 were overweight and 93 were normal weight. External fixation was applied to the tibia in 82 cases, to the femur in 77 and to both in 49. Mean duration of fixation was 160 days (range, 31 to 570 d) and patients were followed for a mean of 3.9 years (range, 1.0 to 12.0 y). There was no statistically significant difference in the rate of complications between the 3 groups (P=0.61). In the obese group complications occurred in 68.1% versus 66.7% in the overweight group and 61.3% in normal weight. In the setting of external fixator use for lower-extremity pathology in pediatric patients, there is no association between an increase in complications and obesity as defined by BMI. Complication rates are high when external fixation is utilized for the lower extremity, however, patients and families should not be counseled that increased BMI will add to the burden of orthopaedic complications in this situation.

    The impact of body condition at 110 d of gestation on mammary gland development, mammary gene expression, and hormonal and metabolite status of gilts was studied. Thirty-nine gilts were equally divided into 3 groups based on their backfat thickness at the end of gestation: 1) low backfat (LBF; 12-15 mm), 2) medium backfat (MBF; 17-19 mm), or 3) high backfat (HBF; 21-26 mm). Gilts had similar BW (138.1 ± 8.2 kg) and backfat thicknesses (16.4 ± 1.0 mm) at mating and the 3 groups were achieved via ingestion of varying amounts of feed throughout gestation. Jugular blood samples were obtained from all gilts at mating and at 109 d of gestation to assess hormonal and metabolic statuses, and animals were slaughtered on d 110 to collect mammary glands for compositional analyses and for measure of gene expression. The LBF gilts had less extraparenchymal tissue ( gilts. Mammary parenchyma from LBF gilts also tended to contain less DM ( gilts. None of the 15 genes studied in mammary parenchymal tissue differed in terms of expression level, and the rate of mammary cell proliferation was similar among treatments ( > 0.10). There was a tendency for circulating leptin concentrations on d 109 of gestation to be lower in LBF gilts than in MBF gilts ( gilts did not differ from those of the other treatments ( > 0.10). Current results demonstrate that being too thin at the end of gestation (12-15 mm backfat) has a negative impact on mammary development in gilts, whereas having backfats varying from 17 to 26 mm seems to have no detrimental effects on mammogenesis. Backfat thickness in late pregnancy must therefore be considered to achieve optimal sow lactation performance.

    The effect of body mass index (BMI) reduction following bariatric surgery on subsequent airway management has not been investigated. This study aimed to investigate the association between BMI reduction and airway assessment and management measured by Mallampati class (MC) and laryngoscopy grade (LG). We conducted a retrospective study over 6 years to compare the BMI changes, MC and LG in patients having weight reduction bariatric surgery followed by subsequent surgery. Data was extracted from the anesthesia records of patients undergoing laparoscopic band insertion (LBI) and laparoscopic sleeve gastrectomy (LSG). Difficult airway was defined as Malampati class 3 and 4 on a 1-4 difficulty scale or laryngoscopy grade >2 on a 1-4 difficulty scale and need for unplanned fiberoptic intubation. Changes in these variables were correlated with weight reduction. Statistical analysis included t test, univariante, and multivariant logistic regression. Five hundred forty-six patients underwent LSG and 83 patients had LBI during the study period. Of those patients, 65 patients had subsequent surgical procedures after the bariatric procedure. Of the 65 patients identified, 62 were eligible. BMI decreased by approximately13 kg/m 2 (p = 0.000) which roughly represents a 30 % reduction between the two surgical procedures. Mallampati class decreased significantly (p = 0.000) while laryngoscopy grade did not (p = 0.419). Our study revealed that a significant reduction in BMI was associated with a significant decrease in Mallampati class. There was no significant decrease in laryngoscopy grade, and there was no case of unplanned fiberoptic intubation.

    Full Text Available Abstract Background Metabolic syndrome (MetS and body mass index (BMI, kg.m-2 are established independent risk factors in the development of diabetes; we prospectively examined their relative contributions and joint relationship with incident diabetes in a Middle Eastern cohort. Method participants of the ongoing Tehran lipid and glucose study are followed on a triennial basis. Among non-diabetic participants aged≥ 20 years at baseline (8,121 those with at least one follow-up examination (5,250 were included for the current study. Multivariate logistic regression models were used to estimate sex-specific adjusted odd ratios (ORs and 95% confidence intervals (CIs of baseline BMI-MetS categories (normal weight without MetS as reference group for incident diabetes among 2186 men and 3064 women, aged ≥ 20 years, free of diabetes at baseline. Result During follow up (median 6.5 years; there were 369 incident diabetes (147 in men. In women without MetS, the multivariate adjusted ORs (95% CIs for overweight (BMI 25-30 kg/m2 and obese (BMI≥30 participants were 2.3 (1.2-4.3 and 2.2 (1.0-4.7, respectively. The corresponding ORs for men without MetS were 1.6 (0.9-2.9 and 3.6 (1.5-8.4 respectively. As compared to the normal-weight/without MetS, normal-weight women and men with MetS, had a multivariate-adjusted ORs for incident diabetes of 8.8 (3.7-21.2 and 3.1 (1.3-7.0, respectively. The corresponding ORs for overweight and obese women with MetS reached to 7.7 (4.0-14.9 and 12.6 (6.9-23.2 and for men reached to 3.4(2.0-5.8 and 5.7(3.9-9.9, respectively. Conclusion This study highlights the importance of screening for MetS in normal weight individuals. Obesity increases diabetes risk in the absence of MetS, underscores the need for more stringent criteria to define healthy metabolic state among obese individuals. Weight reduction measures, thus, should be encouraged in conjunction with achieving metabolic targets not addressed by current definition of

    Obesity, in the either kidney donor or the recipient, has been related to worse graft function. The aim of this study was to compare long-term graft outcomes of living-related kidney recipients regarding the donor-to-recipient body mass index (BMI) ratio. From November 2002 to November 2010, 62 consecutive living-related kidney transplantations were performed at our center. Donor and recipient BMIs were categorized by Taiwan's national standard using dividing values of 18.5, 24, and 27 kg/m(2) to divide subjects into donor-to-recipient BMI categories. These with the same BMI category as their donors were defined as the same-BMI group (group 0); recipients with a lower BMI category than their donors were defined as the large-to-small group (group 1); and those with a higher BMI category than their donors were defined as the small-to-large group (group 2). Baseline parameters and posttransplantation follow-up data were analyzed according to this grouping. Of the 57 recipients followed regularly at our hospital (mean follow-up 48.9 months), 21 (36.8.1%) were in group 0; 26 (45.6%) in group 1, and 10 (17.6%) in group 2. The baseline parameters were similar among these groups. The overall graft survival rates were 81.0% in group 0, 76.9% in group 1, and 90.0% in group 2. The rejection-free graft survival rates were 81.0%, 65.4%, and 90.0%, respectively. By Kaplan-Meier analysis, group 1 showed worse rejection-free graft survival than group 0 or group 2 (log-rank P = .046). Living-related recipients of kidneys from donors with a higher BMI showed lower long-term graft survival, which might suggest that petite recipients may need time to compensate adequate blood flow for the relative large graft, thus carrying a higher chance of rejection and worse graft outcomes.

    Background: Evidence suggests that stress plays a role in changes in body weight and disordered eating. The present study examined the effect of mood, affect systems (attachment and social rank) and affect regulatory processes (self-criticism, self-reassurance) on the stress process and how this impacts on changes in weight and disordered eating. Methods: A large sample of women participated in a community-based prospective, longitudinal online study in which measures of body mass index (BMI), disordered eating, perceived stress, attachment, social rank, mood and self-criticism/reassurance were measured at 6-monthly intervals over an 18-month period. Results: Latent Growth Curve Modelling showed that BMI increased over 18 months while stress and disordered eating decreased and that these changes were predicted by high baseline levels of these constructs. Independently of this, however, increases in stress predicted a reduction in BMI which was, itself, predicted by baseline levels of self-hatred and unfavourable social comparison. Conclusions: This study adds support to the evidence that stress is important in weight change. In addition, this is the first study to show in a longitudinal design, that social rank and self-criticism (as opposed to self-reassurance) at times of difficulty predict increases in stress and, thus, suggests a role for these constructs in weight regulation.

    The aim of this work has been to assess the effect of diet density [control (CON) or 15% diluted (DIL)] and growth curve [recommended by the genetic line (RBW) or 15% heavier (HBW)] and their interaction on BW uniformity, feeding motivation, behavior, and body composition of broiler breeder pullets. A total of 3,000 one-day-old female breeders Ross 308, distributed in 20 pens, was randomly assigned to each treatment. Feed allowance was weekly adjusted to reach the desired BW. Feed was provided as pelleted (zero to 3 wk) and crumble (4 to 19 wk). Time eating was measured at 7, 11, and 19 weeks. A feeding rate test was performed after 11 weeks. Behavior was observed at 9 and 15 wk, by visual scan. At 6, 13, and 19 wk of age, one bird/pen was slaughtered for weighing different organs and analyzing the composition of empty whole bodies. Treatments did not affect BW uniformity; relative weights of the ovary, oviduct, or gizzard; or protein content of empty BW. Time eating varied with the growth curve at 19 wk (P Behavior was affected by the age and by the time of the d measured, but it did not change with the treatments. Birds spent most time pecking objects (50%), feeding (28%), and drinking (17%). Pullets fed DIL had 8% lower breast yield at different ages and higher empty digestive tracts at 6 weeks. Body composition varied with age; fat content increased from 12.7 to 15.9 to 19.8% for 6, 13, and 19 wk, respectively. The lowest body fat was observed for RBW pullets fed DIL (P = 0.003) at 19 weeks. Feeding DIL diets to HBW pullets could be done to increase the time spent eating and reduce their feeling of hunger without negative effects on body composition. However, its influence on behavior and BW uniformity was not proved. © The Author 2017. Published by Oxford University Press on behalf of Poultry Science Association.

    1. The objective of this study was to evaluate the effect of maternal stress (MS) induced by supplementing the hen's diet with 2 mg/hen/d dietary corticosterone (CORT) on embryonic development, biochemical blood parameters and hatching performance of broiler chicks. 2. A total of 200 Ross broiler breeder hens at 42 weeks of age were randomly divided into two groups: MS or control. Hens in the MS were fed 2 mg/hen/d CORT for 14 d. Eggs (648 and 635 eggs for MS and control, respectively) were collected from d 3 to 14 of dietary CORT supplementation and incubated. Weights of embryo, chicks and organs and body composition were determined during incubation and at hatch. Biochemical blood parameters were measured at internal pipping stage and day of hatch. Hatching performance and embryonic mortalities were recorded. 3. Hens fed a diet supplemented with CORT had lighter body weight and produced less eggs at the end of the 14-d treatment period. Although MS embryos were heavier than control from 12 to 18 d of incubation, chick weight was similar at the day of hatch. Lower relative weights for yolk sac and bursa were observed at 12 d of incubation for MS chicks compared to control. Chicks from both groups had similar body content in spite of higher fat content of MS embryos on d 18 of incubation. 4. MS had no effect on the duration of incubation or hatching performance but increased mortality at the pipping stage. 5. The results suggest that hormone-mediated MS might affect embryonic development during incubation without adverse effect on chick weight and body composition.

    [Purpose] The purpose of the present study was to examine the effects of progressive body weight supported treadmill forward and backward walking training (PBWSTFBWT), progressive body weight supported treadmill forward walking training (PBWSTFWT), progressive body weight supported treadmill backward walking training (PBWSTBWT), on stroke patients' affected side lower extremity's walking ability. [Subjects and Methods] A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the affected side lower extremity's walking ability, step length of the affected side, stance phase of the affected side, swing phase of the affected side, single support of the affected side, and step time of the affected side were measured using optogait and the symmetry index. [Results] In the within group comparisons, all the three groups showed significant differences between before and after the intervention and in the comparison of the three groups, the PBWSTFBWT group showed more significant differences in all of the assessed items than the other two groups. [Conclusion] In the present study progressive body weight supported treadmill training was performed in an environment in which the subjects were actually walked, and PBWSTFBWT was more effective at efficiently training stroke patients' affected side lower extremity's walking ability.

    control are "emotional eating" and "externality", which represent an individual's vulnerability to eat in response to emotional states or external cues, respectively. These questionnaires have been translated into French and validated for the French population. Average data are available for normal weight and obese French men and women. A gender difference is often reported: women, and even young girls, tend to have higher scores than males for most dimensions. These questionnaires have been extensively used in populations without psychiatric disorders, with the only exception of diagnosed eating disorders such as anorexia and bulimia nervosa. The questionnaires have not been used until now in populations with other types of psychiatric disorders, such as schizophrenia or bipolar disease. Their relevance for such populations is now an important question, since last generation pharmaceutical treatments of such psychiatric disorders seem to adversely affect body weight control. It then becomes critical to know whether the psychological dimensions assessed by such questionnaires reflect the action of pharmacological agents that induce weight gain. A research project is now in progress at Sainte-Anne Hospital to investigate many dimensions of the motivation to eat, as assessed by the questionnaires, in psychiatric patients receiving various types of antipsychotic agents. The results of this original study might provide hints about the mechanisms that lead to body weight gain in patients receiving certain types of antipsychotic pharmacological agents and potentially help in preventing or reversing the weight gain associated with such treatments.

    Cordyceps militaris is a highly valued edible and medicinal fungus due to its production of various metabolites, including adenosine, cordycepin, N 6 -(2-hydroxyethyl)-adenosine, and carotenoids. The contents of these metabolites are indicative of the quality of commercially available fruit body of this fungus. In this work, the effects of environmental abiotic factors, including heat and light stresses, on the fruit body growth and metabolite production in C. militaris were evaluated during the late growth stage. The optimal growth temperature of C. militaris was 20 °C. It was found that a heat stress of 25 °C for 5-20 days during the late growth stage significantly promoted cordycepin and carotenoid production without affecting the biological efficiency. Light stress at 6000 lx for 5-20 days during the late growth stage significantly promoted cordycepin production but decreased the carotenoid content. Both heat and light stresses promoted N 6 -(2-hydroxyethyl)-adenosine production. In addition, gene expression analysis showed that there were simultaneous increases in the expression of genes encoding a metal-dependent phosphohydrolase (CCM_04437) and ATP phosphoribosyltransferase (CCM_04438) that are involved in the cordycepin biosynthesis pathway, which was consistent with the accumulation of cordycepin during heat stress for 5-20 days. A positive weak correlation between the cordycepin and adenosine contents was observed with a Pearson correlation coefficient of 0.338 (P < 0.05). The results presented herein provide a new strategy for the production of a superior quality fruit body of C. militaris and contribute to further elucidation of the effects of abiotic stress on metabolite accumulation in fungi.

    Full Text Available It has been empirically established through many controlled studies that one of the most rewarding experiences known to humanity is listening to music, especially because it affects various parts of the brain and causes emotional arousal. The aim of this article is to do a succinct study on music and its effect on, especially, the nervous system, by referring to various empirical studies undertaken on the subject. The article, therefore, has a twofold purpose: (1 to show that throughout history, music has played a special role in various cultures and religions, especially as a healing tool and (2 to demonstrate that sound frequencies and vibrations found in music have the potential to realign the emotions of the nervous system and bring the body back into harmony by reducing stress.Intradisciplinary and/or interdisciplinary implications: The article�s challenge and purpose are to show that science and religion are not in conflict, but rather that together they can benefit both disciplines and make better sense of complicated topics, especially those related to how natural science and religion deal with the human body and health, and its relationship to the mind.

    Cigarette smoking and obesity are two major public health problems. However, factors related to the underlying risk for being overweight are not well established. Certain demographic, smoking, and psychological factors have been linked to overweight/obese body mass. The current study examined a multivariate risk model, stratified by gender, in order to better explicate the nature of overweight body mass among daily smokers. In a sample of treatment-seeking smokers (n = 395), among males and females, (1) older age, (2) stronger expectancies about the weight/appetite control effects of smoking, (3) greater smoking-based inflexibility/avoidance due to smoking-related sensations, and (4) less problematic alcohol use, were associated with being overweight. Additionally, among males, having a tobacco-related medical problem and higher tolerance for physical discomfort aided in the discriminant function model for classifying smokers as overweight. Together, numerous cognitive-affective vulnerabilities and smoking processes may be targetable and potentially inform weight-related prevention programs among smokers.

    The goal of this project was to determine if different body conditions in late gestation that are due to varying body conditions at mating affect mammary development and mammary gene expression of gilts. Gilts that were fed ad libitum in the growing period were selected based on their backfat depths to form 3 groups at mating, namely, low backfat (LBF; 12-15 mm; = 14), medium backfat (MBF; 17-19 mm; = 15), and high backfat (HBF; 22-26 mm; = 16). During gestation, LBF, MBF, and HBF gilts were fed approximately 1.25, 1.43, and 1.63 times maintenance requirements to maintain their differences in body condition. Feed intake was increased by 1 kg in the last 10 d of gestation. Backfat depths of gilts were ultrasonically measured at mating and on d 30, 50, 70, 100, and 109 of gestation. Blood samples were obtained at mating and on d 109 of gestation to measure concentrations of IGF-1, glucose, insulin, estradiol, urea, free fatty acids, leptin, and adiponectin. Gilts were slaughtered on d 110 of gestation to collect mammary glands for compositional analyses. Mammary extraparenchymal tissue weight was lesser in LBF and MBF gilts than in HBF gilts (1,259.3, 1,402.7, and 1,951.5 ± 70.4 g, respectively; 0.10), but its composition was altered. Concentrations of DNA and RNA decreased as backfat depth increased ( gilts than in HBF gilts. On d 109 of gestation, concentrations of insulin ( gilts than in HBF gilts, whereas those of urea were greater ( 0.10) with the exception of , which had a greater expression level in LBF gilts than in MFB or HBF gilts ( gilts than in LBF gilts ( gilts that were present at mating were maintained throughout gestation, it had an impact on mammary development. Extraparenchymal tissue mass was affected and, more importantly, composition of parenchymal tissue was altered, indicating a beneficial effect of gilts being in the thinner treatment groups at mating.

    Purpose: We sought to determine whether the total body irradiation (TBI) schedule affected outcome in patients with acute leukemia in complete remission who received T cell–depleted allogeneic hematopoietic stem cell transplantation from HLA identical siblings. Methods and Materials: The study recruited 55 patients (median age, 48 years; age range, 20-66 years; 30 men and 25 women; 34 with acute myeloid leukemia and 21 with acute lymphoid leukemia). Hyperfractionated TBI (HTBI) (1.2 Gy thrice daily for 4 days [for a total dose of 14.4 Gy] from day −12 to day −9) was administered to 29 patients. Single-dose TBI (STBI) (8 Gy, at a median dose rate of 10.7 cGy/min on day −9) was given to 26 patients. Results: All patients achieved primary, sustained engraftment with full donor-type chimerism. At 10 years, the overall cumulative incidence of transplant-related mortality was 11% (SE, ±0.1%). It was 7% (SE, ±0.2%) after HTBI and 15% (SE, ±0.5%) after STBI (P=.3). The overall cumulative incidence of relapse was 33% (SE, ±0.5). It was 13% (SE, ±0.5%) after HTBI and 46% (SE, ±1%) after STBI (P=.02). The overall probability of disease-free survival (DFS) was 59% (SE, ±7%). It was 67% (SE, ±0.84%) after HTBI and 37% (SE, ±1.4%) after STBI (P=.01). Multivariate analyses showed the TBI schedule was the only risk factor that significantly affected relapse and DFS (P=.01 and P=.03, respectively). Conclusions: In patients with acute leukemia, HTBI is more efficacious than STBI in eradicating minimal residual disease after HLA-matched T cell–depleted hematopoietic stem cell transplantation, thus affecting DFS.

    Some insect species are capable of producing an enhanced immune response after a first pathogenic encounter, a process called immune priming. However, whether and how such ability is driven by particular diet components (protein/carbohydrate) have not been explored. Such questions are sound given that, in general, immune response is dietary dependent. We have used adults of the house cricket Acheta domesticus L. (Orthoptera: Gryllidae) and exposed them to the bacteria Serratia marcescens. We first addressed whether survival rate after priming and nonpriming treatments is dietary dependent based on access/no access to proteins and carbohydrates. Second, we investigated how these dietary components affected fat reserves, muscle mass, and body weight, three key traits in insect fitness. Thus, we exposed adult house crickets to either a protein or a carbohydrate diet and measured the three traits. After being provided with protein, primed animals survived longer compared to the other diet treatments. Interestingly, this effect was also sex dependent with primed males having a higher survival than primed females when protein was supplemented. For the second experiment, protein-fed animals had more fat, muscle mass, and body weight than carbohydrate-fed animals. Although we are not aware of the immune component underlying immune priming, our results suggest that its energetic demand for its functioning and/or consequent survival requires a higher demand of protein with respect to carbohydrate. Thus, protein shortage can impair key survival-related traits related to immune and energetic condition. Further studies varying nutrient ratios should verify our results.

    Along with global warming, drought disasters are occurring more frequently and are seriously affecting normal life and food security in China. Drought risk assessments are necessary to provide support for local governments. This study aimed to establish an integrated drought risk model based on the relation curve of drought joint probabilities and drought losses of multi-hazard-affected bodies. First, drought characteristics, including duration and severity, were classified using the 1953-2010 precipitation anomaly in the Taoerhe Basin based on run theory, and their marginal distributions were identified by exponential and Gamma distributions, respectively. Then, drought duration and severity were related to construct a joint probability distribution based on the copula function. We used the EPIC (Environmental Policy Integrated Climate) model to simulate maize yield and historical data to calculate the loss rates of agriculture, industry, and animal husbandry in the study area. Next, we constructed vulnerability curves. Finally, the spatial distributions of drought risk for 10-, 20-, and 50-year return periods were expressed using inverse distance weighting. Our results indicate that the spatial distributions of the three return periods are consistent. The highest drought risk is in Ulanhot, and the duration and severity there were both highest. This means that higher drought risk corresponds to longer drought duration and larger drought severity, thus providing useful information for drought and water resource management. For 10-, 20-, and 50-year return periods, the drought risk values ranged from 0.41 to 0.53, 0.45 to 0.59, and 0.50 to 0.67, respectively. Therefore, when the return period increases, the drought risk increases.

    The purpose of this study was to identify factors affecting local control of stereotactic body radiotherapy (SBRT) for lung tumors including primary lung cancer and metastatic lung tumors. Between June 2006 and June 2009, 159 lung tumors in 144 patients (primary lung cancer, 128; metastatic lung tumor, 31) were treated with SBRT with 48-60 Gy (mean 50.1 Gy) in 4-5 fractions. Higher doses were given to larger tumors and metastatic tumors in principle. Assessed factors were age, gender, tumor origin (primary vs. metastatic), histological subtype, tumor size, tumor appearance (solid vs. ground glass opacity), maximum standardized uptake value of positron emission tomography using 18 F-fluoro-2-deoxy-D-glucose, and SBRT doses. Follow-up time was 1-60 months (median 18 months). The 1-, 2-, and 3-year local failure-free rates of all lesions were 90, 80, and 77%, respectively. On univariate analysis, metastatic tumors (p<0.0001), solid tumors (p=0.0246), and higher SBRT doses (p=0.0334) were the statistically significant unfavorable factors for local control. On multivariate analysis, only tumor origin was statistically significant (p=0.0027). The 2-year local failure-free rates of primary lung cancer and metastatic lung tumors were 87 and 50%, respectively. A metastatic tumor was the only independently significant unfavorable factor for local control after SBRT. (author)

    Genetic defects in protein O-mannosyltransferase 1 (POMT1) and POMT2 underlie severe muscular dystrophies. POMT genes are evolutionarily conserved in metazoan organisms. In Drosophila , both male and female POMT mutants show a clockwise rotation of adult abdominal segments, suggesting a chirality of underlying pathogenic mechanisms. Here we described and analyzed a similar phenotype in POMT mutant embryos that shows left-handed body torsion. Our experiments demonstrated that coordinated muscle contraction waves are associated with asymmetric embryo rolling, unveiling a new chirality marker in Drosophila development. Using genetic and live-imaging approaches, we revealed that the torsion phenotype results from differential rolling and aberrant patterning of peristaltic waves of muscle contractions. Our results demonstrated that peripheral sensory neurons are required for normal contractions that prevent the accumulation of torsion. We found that POMT mutants show abnormal axonal connections of sensory neurons. POMT transgenic expression limited to sensory neurons significantly rescued the torsion phenotype, axonal connectivity defects, and abnormal contractions in POMT mutant embryos. Together, our data suggested that protein O-mannosylation is required for normal sensory feedback to control coordinated muscle contractions and body posture. This mechanism may shed light on analogous functions of POMT genes in mammals and help to elucidate the etiology of neurological defects in muscular dystrophies. SIGNIFICANCE STATEMENT Protein O-mannosyltransferases (POMTs) are evolutionarily conserved in metazoans. Mutations in POMTs cause severe muscular dystrophies associated with pronounced neurological defects. However, neurological functions of POMTs remain poorly understood. We demonstrated that POMT mutations in Drosophila result in abnormal muscle contractions and cause embryo torsion. Our experiments uncovered a chirality of embryo movements and a unique POMT -dependent

    A transcriptomic approach was used to evaluate potential interactions between prepartum body condition score (BCS) and feeding management in the weeks before calving on hepatic metabolism during the periparturient period. Thirty-two mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to one of four treatment groups in a 2 × 2 factorial arrangement: two prepartum BCS categories [4.0 (thin, BCS4) and 5.0 (optimal, BCS5); based on a 10-point scale], and two levels of energy intake during the 3 weeks preceding calving (75 and 125 % of estimated requirements). Liver samples were obtained at -7, 7, and 28 d relative to parturition and subsequent RNA was hybridized to the Agilent 44 K Bovine (V2) Microarray chip. The Dynamic Impact Approach was used for pathway analysis, and Ingenuity Pathway Analysis was used for gene network analysis. The greater number of differentially expressed genes in BCS4 cows in response to prepartum feed allowance (1071 vs 310, over the entire transition period) indicates that these animals were more responsive to prepartum nutrition management than optimally-conditioned cows. However, independent of prepartum BCS, pathway analysis revealed that prepartal feeding level had a marked effect on carbohydrate, amino acid, lipid, and glycan metabolism. Altered carbohydrate and amino acid metabolism suggest a greater and more prolonged negative energy balance postpartum in BCS5 cows overfed prepartum. This is supported by opposite effects of prepartum feeding in BCS4 compared with BCS5 cows in pathways encompassing amino acid, vitamin, and co-factor metabolism. The prepartum feed restriction ameliorates the metabolic adaptation to the onset of lactation in BCS5 cows, while detrimentally affecting BCS4 cows, which seem to better adapt when overfed. Alterations in the glycosaminoglycans synthesis pathway support this idea, indicating better hepatic health status in feed-restricted BCS5 and overfed BCS4 cows

    Male body size can play an important role in the mating systems of anuran amphibians. We conducted laboratory-based trials with cane toads Rhinella (Bufo) marina from an invasive population in the wet-dry tropics of northern Australia, to clarify the effects of a male's body size on his reproductive success and behavior (mate choice). Males were stimulated with a synthetic hormone to induce reproductive readiness. Larger body size enhanced a male toad's ability to displace a smaller rival fro...

    Although self-harm has been observed among patients with eating disorders, the effects of such tendencies on treatment outcomes are unclear. The current study employed structural equation modeling to (a) evaluate the relationship between self-harm and changes in body dissatisfaction and drive for thinness in a large sample of patients (n = 2061) who underwent inpatient treatment, and (b) to examine whether the relationship between self-harm and changes in body dissatisfaction and drive for thinness during inpatient treatment remains significant when controlling for change in negative affect during treatment. Results revealed that patients with a history of self-harm reported significantly less reduction in body dissatisfaction and drive for thinness following treatment. Patients experiencing less change in negative affect also reported significantly less reduction in body dissatisfaction and drive for thinness after discharge from treatment. However, the association between history of self-harm and reduction in body dissatisfaction and drive for thinness after treatment became non-significant when controlling for change in negative affect. This pattern of findings was also replicated among patients with a primary diagnosis of anorexia nervosa (n = 845), bulimia nervosa (n = 565), and eating disorder not otherwise specified (n = 651). The implications of these findings for delineating the specific role of self-harm in the nature and treatment of eating disorders are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Viewing idealized images has been shown to reduce men's body satisfaction; however no research has examined the impact of music video clips. This was the first study to examine the effects of exposure to muscular images in music clips on men's body image, mood and cognitions. Ninety men viewed 5 min of clips containing scenery, muscular or average-looking singers, and completed pre- and posttest measures of mood and body image. Appearance schema activation was also measured. Men exposed to the muscular clips showed poorer posttest levels of anger, body and muscle tone satisfaction compared to men exposed to the scenery or average clips. No evidence of schema activation was found, although potential problems with the measure are noted. These preliminary findings suggest that even short term exposure to music clips can produce negative effects on men's body image and mood. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Although obesity is a well-studied risk factor for diabetes, there remains an interest in whether "increasing body mass index (BMI)," "high BMI per se," or both are the actual risk factors for diabetes. The present study aimed to retrospectively compare BMI trajectories of individuals with and without diabetes in a case-control design and to assess whether increasing BMI alone would be a risk factor. Using comprehensive health check-up data measured over ten years, we conducted a case-control study and graphically drew the trajectories of BMIs among diabetic patients and healthy subjects, based on coefficients in fitted linear mixed-effects models. Patient group was matched with healthy control group at the onset of diabetes with an optimal matching method in a 1:10 ratio. Simple fixed-effects models assessed the differences in increasing BMIs over 10 years between patient and control groups. At the time of matching, the mean ages in male patients and controls were 59.3 years [standard deviation (SD) = 9.2] and 57.7 years (SD = 11.2), whereas the mean BMIs were 25.0 kg/m(2) (SD = 3.1) and 25.2 kg/m(2) (SD = 2.9), respectively. In female patients and controls, the mean ages were 61.4 years (SD = 7.9) and 60.1 years (SD = 9.6), whereas the mean BMIs were 24.8 kg/m(2) (SD = 3.5) and 24.9 kg/m(2) (SD = 3.4), respectively. The simple fixed-effects models detected no statistical significance for the differences of increasing BMIs between patient and control groups in males (P = 0.19) and females (P = 0.67). Sudden increases in BMI were observed in both male and female patients when compared with BMIs 1 year prior to diabetes onset. The present study suggested that the pace of increasing BMIs is similar between Japanese diabetic patients and healthy individuals. The increasing BMI was not detected to independently affect the onset of type 2 diabetes.

    Calving body condition score (BCS) is an important determinant of early-lactation dry matter intake, milk yield, and disease incidence. The current study investigated the metabolic and molecular changes induced by the change in BCS. A group of cows of mixed age and breed were managed from the second half of the previous lactation to achieve mean group BCS (10-point scale) that were high (HBCS, 5.5; n=20), medium (MBCS, 4.5; n=18), or low (LBCS, 3.5; n=19). Blood was sampled at wk -4, -3, -2, 1, 3, 5, and 6 relative to parturition to measure biomarkers of energy balance, inflammation, and liver function. Liver was biopsied on wk 1, 3, and 5 relative to parturition, and 10 cows per BCS group were used for transcript profiling via quantitative PCR. Cows in HBCS and MBCS produced more milk and had greater concentrations of nonesterified fatty acids and β-hydroxybutyrate postpartum than LBCS. Peak concentrations of nonesterified fatty acids and β-hydroxybutyrate and greater hepatic triacylglycerol concentrations were recorded in HBCS at wk 3. Consistent with blood biomarkers, HBCS and MBCS had greater expression of genes associated with fatty acid oxidation (CPT1A, ACOX1), ketogenesis (HMGCS2), and hepatokines (FGF21, ANGPTL4), whereas HBCS had the lowest expression of APOB (lipoprotein transport). Greater expression during early lactation of BBOX1 in MBCS and LBCS suggested greater de novo carnitine synthesis. The greater BCS was associated with lower expression of growth hormone/insulin-like growth factor-1 signaling axis genes (GHR1A, IGF1, and IGFALS) and greater expression of gluconeogenic genes. These likely contributed to the higher milk production and greater gluconeogenesis. Despite greater serum haptoglobin around calving, cows in HBCS and MBCS had greater blood albumin. Cows in MBCS, however, had a higher albumin:globulin ratio, probably indicating a less pronounced inflammatory status and better liver function. The marked decrease in expression of NFKB1

    The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 African Black unsexed ostrich chicks were used in the present study in simple randomized design. The results of the present work indicated that initial and final live body weight, body weight gain, feed consumption, feed conversion of ostrich chicks were insignificantly affected by dietary protein level used. Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP. Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level. Body height and tibiotarsus length were not significantly different. In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%).

  4. The Arc from the Body to Culture: How Affect, Proprioception, Kinesthesia, and Perceptual Imagery Shape Cultural Knowledge (and vice versa

    2013-06-01

    Full Text Available This essay approaches the complex triadic relation between concepts, body, and culture from an angle rooted in the empirical cognitive research of the past three decades or so. Specifically, it reviews approaches to how the body shapes conceptualization, reasoning, and communication. One main section examines how the body contributes to cultural learning and another how abstract cultural concepts are grounded in sensorimotor experience, perception, and inner somatic states. Their purpose is to survey and briefly critique different theoretical frameworks, probe into their complementarity, and summarily evaluate to what extent higher cognition is embodied. The third main section outlines elements of an epistemological framework that connects culture, concepts, and the body in a sensible way. The paper closes with a discussion of how the embodied cognition paradigm advances a rapprochement of different areas both within cognitive research and beyond.

    Previous studies have already found a positive association between attachment and disordered eating attitudes and behaviors in children and adolescents. However, to our knowledge, no experimental studies have examined whether changes in negative and/or positive affect moderate the association between attachment anxiety and body dissatisfaction in children. A controlled laboratory setting was used to investigate whether changes in state negative and/or positive affect moderate the association between attachment anxiety and body satisfaction in a sample of 81 children (M age =11.74). The changes in state affect were caused by the exposure to a performance-related stressor using the Trier Social Stress Test for Children. Children with high levels of attachment anxiety reported a decrease in body satisfaction, but only if the TSST-C led to a decrease in their positive affect. Early detection and intervention programs may benefit from addressing insecure attachment and maladaptive emotion regulation in children. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Tropomyosin, one of major actin-filament binding proteins, regulates actin-myosin interaction and actin filament stability. Multicellular organisms express a number of tropomyosin isoforms, but understanding of isoform-specific tropomyosin functions is incomplete. The nematode Caenorhabditis elegans has a single tropomyosin gene, lev-11 , which has been reported to express four isoforms by using two separate promoters and alternative splicing. Here, we report a fifth tropomyosin isoform, LEV-11O, which is produced by alternative splicing which includes a newly identified seventh exon, exon 7a. By visualizing specific splicing events in vivo , we find that exon 7a is predominantly selected in a subset of the body wall muscles in the head, while exon 7b, which is alternative to exon 7a, is utilized in the rest of the body. Point mutations in exon 7a and exon 7b cause resistance to levamisole-induced muscle contraction specifically in the head and the main body, respectively. Overexpression of LEV-11O, but not LEV-11A, in the main body results in weak levamisole resistance. These results demonstrate that specific tropomyosin isoforms are expressed in the head and body regions of the muscles and differentially contribute to the regulation of muscle contractility. © 2018 by The American Society for Cell Biology.

    Green tea (GT) extract may play a role in body weight regulation. Suggested mechanisms are decreased fat absorption and increased energy expenditure. We examined whether GT supplementation for 12 wk has beneficial effects on weight control via a reduction in dietary lipid absorption as well as an increase in resting energy expenditure (REE). Sixty Caucasian men and women [BMI (in kg/m²): 18-25 or >25; age: 18-50 y] were included in a randomized placebo-controlled study in which fecal energy content (FEC), fecal fat content (FFC), resting energy expenditure, respiratory quotient (RQ), body composition, and physical activity were measured twice (baseline vs. week 12). For 12 wk, subjects consumed either GT (>0.56 g/d epigallocatechin gallate + 0.28-0.45 g/d caffeine) or placebo capsules. Before the measurements, subjects recorded energy intake for 4 consecutive days and collected feces for 3 consecutive days. No significant differences between groups and no significant changes over time were observed for the measured variables. Overall means ± SDs were 7.2 ± 3.8 g/d, 6.1 ± 1.2 MJ/d, 67.3 ± 14.3 kg, and 29.8 ± 8.6% for FFC, REE, body weight, and body fat percentage, respectively. GT supplementation for 12 wk in 60 men and women did not have a significant effect on FEC, FFC, REE, RQ, and body composition. © 2015 American Society for Nutrition.

    The objective of the present study is to investigate the relationships between body composition, nutritional profile, muscular fitness (MF) and bone health in a sample of children and adolescents from Colombia. Participants included 1118 children and adolescents (54.6% girls). Calcaneal broadband ultrasound attenuation (c-BUA) was obtained as a marker of bone health. Body composition (fat mass and lean mass) was assessed using bioelectrical impedance analysis. Furthermore height, weight, waist circumference and Tanner stage were measured and body mass index (BMI) was calculated. Standing long-jump (SLJ) and isometric handgrip dynamometry were used respectively as indicators of lower and upper body muscular fitness. A muscular index score was also computed by summing up the standardised values of both SLJ and handgrip strength. Dietary intake and degree of adherence to the Mediterranean diet were assessed by a 7-day recall questionnaire for food frequency and the Kidmed questionnaire. Poor bone health was considered using a z-score cut off of ≤−1.5 standard deviation. Once the results were adjusted for age and Tanner stage, the predisposing factors of having a c-BUA z-score ≤−1.5 standard deviation included being underweight or obese, having an unhealthy lean mass, having an unhealthy fat mass, SLJ performance, handgrip performance, and unhealthy muscular index score. In conclusion, body composition (fat mass and lean body mass) and MF both influenced bone health in a sample of children and adolescents from Colombia. Thus promoting strength adaptation and preservation in Colombian youth will help to improve bone health, an important protective factor against osteoporosis in later life. PMID:28165360

    An 8-week feeding trial was carried out with juvenile yellow catfish to study the effects of dietary available phosphorus (P) on growth performance, body composition, and hepatic antioxidant property. Six pellet diets were formulated to contain graded available P levels at 0.33, 0.56, 0.81, 1.15, 1.31, and 1.57% of dry matter, respectively. Triplicate tanks with each tank containing 60 juveniles (3.09 ± 0.03 g) were fed one of the six experimental diets for 8 weeks. Specific growth rate, feeding rate, and protein efficiency ratio were significantly higher at 0.81% dietary available P. Efficiency of P utilization distinctly decreased with increasing P level. Body lipid content significantly decreased while body ash and feces P content significantly increased with increasing P level. Quadratic regression analysis indicated that vertebrae P content was maximized at 1.21% dietary available P. Fish fed 1.57% dietary available P had highest activity of hepatic superoxide dismutase and catalase and malonaldehyde content. In conclusion, decreasing dietary available P increased P utilization efficiency and body lipid content while decreased vertebrae P content. Juvenile yellow catfish were subjected to oxidative damage under the condition of high dietary P content (1.57%), and the damage could not be eradicated by their own antioxidant defense system.

    Mosquitoes display biting preferences among different sites of the human body. In addition to height or convection currents, body odour may play a role in the selection of these biting sites. Previous studies have shown that skin emanations are important host-finding cues for mosquitoes. In this study, skin emanations were collected from armpits, hands and feet; the volatile profiles were analysed and tested for their attractiveness to the malaria mosquito Anopheles coluzzii. Skin emanations collected from armpits were less attractive to An. coluzzii compared to hands or/and feet. The difference may have been caused by deodorant residues, which were found in the armpit samples and not in those of hands and feet. In a subsequent experiment, volunteers were asked to avoid using skincare products for five days, and thereafter, no differences in attractiveness of the body parts to mosquitoes were found. The detected deodorant compound isopropyl tetradecanoate inhibited mosquito landings in a repellent bioassay. It is concluded that the volatiles emanated from different body parts induced comparable levels of attraction in mosquitoes, and that skincare products may reduce a person's attractiveness to mosquitoes.

    Rats place their tails underneath their body trunks when cold (tail-hiding behavior). The aim of the present study was to determine whether this behavior is necessary to maintain body temperature. Male Wistar rats were divided into 'fed' and '42-h fasting' groups. A one-piece tail holder (8.4 cm in length) that prevented the tail-hiding behavior or a three-piece tail holder (2.8 cm in length) that allowed for the tail-hiding behavior was attached to the tails of the rats. The rats were exposed to 27°C for 180 min or to 20°C for 90 min followed by 15°C for 90 min with continuous body temperature and oxygen consumption measurements. Body temperature decreased by -1.0 ± 0.1°C at 15°C only in the rats that prevented tail-hiding behavior of the 42-h fasting group, and oxygen consumption increased at 15°C in all animals. Oxygen consumption was not different between the rats that prevented tail-hiding behavior and the rats that allowed the behavior in the fed and 42-h fasting groups under ambient conditions. These results show that the tail-hiding behavior is involved in thermoregulation in the cold in fasting rats.

    Satisfaction with appearance is of central importance for psychological well-being and health. For individuals with an unusual appearance, such as congenital craniofacial anomalies (CFA), appearance evaluations could be especially important. However, few, if any papers have presented a comprehensive synthesis of the factors found to affect subjective satisfaction with appearance among children, adolescents, and adults born with a CFA. Further, only a handful of craniofacial studies have applied psychological theories or models to their findings, resulting in an overall lack of guidance for researchers in the field. This paper summarises the literature pertaining to satisfaction with appearance among those affected by CFAs, and examines the extent to which Cash's cognitive-behavioural model of body image development (2012) fits with this literature. Given the overlap between factors of interest in the field of CFAs, and in the area of body image more broadly, a closer collaboration between the two research fields is suggested.

    Variations in male body size are known to affect inter- and intrasexual selection outcomes in a wide range of animals. In mating systems involving sexual signaling before mating, body size often acts as a key factor affecting signal strength and mate choice. We evaluated the effect of male size on courtship displays and mating success of the olive fruit fly, Bactrocera oleae (Diptera: Tephritidae). Wing vibrations performed during successful and unsuccessful courtships by large and small males were recorded by high-speed videos and analyzed through frame-by-frame analysis. Mating success of large and small males was investigated. The effect of male-male competition on mating success was evaluated. Male body size affected both male courtship signals and mating outcomes. Successful males showed wing-borne signals with high frequencies and short interpulse intervals. Wing vibrations displayed by successful large males during copulation attempt had higher frequencies over smaller males and unsuccessful large males. In no-competition conditions, large males achieved higher mating success with respect to smaller ones. Allowing large and small males to compete for a female, large males achieve more mating success over smaller ones. Mate choice by females may be based on selection of the larger males, able to produce high-frequency wing vibrations. Such traits may be indicative of "good genes," which under sexual selection could means good social-interaction genes, or a good competitive manipulator of conspecifics. © 2015 Institute of Zoology, Chinese Academy of Sciences.

    Full Text Available Abstract Background The objective of the present study was to map candidate loci influencing naturally occurring variation in triacylglycerol (TAG storage using quantitative complementation procedures in Drosophila melanogaster. Based on our results from Drosophila, we performed a human population-based association study to investigate the effect of natural variation in LAMA5 gene on body composition in humans. Results We identified four candidate genes that contributed to differences in TAG storage between two strains of D. melanogaster, including Laminin A (LanA, which is a member of the α subfamily of laminin chains. We confirmed the effects of this gene using a viable LanA mutant and showed that female flies homozygous for the mutation had significantly lower TAG storage, body weight, and total protein content than control flies. Drosophila LanA is closely related to human LAMA5 gene, which maps to the well-replicated obesity-linkage region on chromosome 20q13.2-q13.3. We tested for association between three common single nucleotide polymorphisms (SNPs in the human LAMA5 gene and variation in body composition and lipid profile traits in a cohort of unrelated women of European American (EA and African American (AA descent. In both ethnic groups, we found that SNP rs659822 was associated with weight (EA: P = 0.008; AA: P = 0.05 and lean mass (EA: P= 0.003; AA: P = 0.03. We also found this SNP to be associated with height (P = 0.01, total fat mass (P = 0.01, and HDL-cholesterol (P = 0.003 but only in EA women. Finally, significant associations of SNP rs944895 with serum TAG levels (P = 0.02 and HDL-cholesterol (P = 0.03 were observed in AA women. Conclusion Our results suggest an evolutionarily conserved role of a member of the laminin gene family in contributing to variation in weight and body composition.

    Introduced American Bullfrogs (Rana catesbeiana) have established breeding populations in several provinces in China since their introduction in 1959. Although Bullfrogs are viewed as a potentially important predator of Chinese native anurans, their impacts in the field are difficult to quantify. We used two experiments to examine factors likely to mediate Bullfrog predation on native anurans. First, we examined effects of Bullfrog size and sex on daily consumption of a common Chinese native (Rana limnocharis). Second, we examined whether Bullfrogs consumed similar proportions of four Chinese natives: Black-Spotted Pond Frog (Rana nigromaculata), Green Pond Frog (Rana plancyi plancyi), Rice Frog (R. limnocharis), and Zhoushan Toad (Bufo bufo gargarizans). We found that larger Rana catesbeiana consumed more R. limnocharis per day than did smaller R. catesbeiana, and that daily consumption of R. limnocharis was positively related to R. catesbeiana body size. When provided with adults of four anurans that differed significantly in body size, R. catesbeiana consumed more individuals of the smallest species (R. limnocharis). However, when provided with similarly sized juveniles of the same four species, R. catesbeiana did not consume any species more than expected by chance. Our results suggest that body size plays an important role in the predatory interactions between R. catesbeiana and Chinese native anurans and that, other things being equal, smaller species and individuals are at greater risk of predation by R. catesbeiana.

    Full Text Available Background: The toxicities of pharmaceuticals for chronic arthritis and osteoporosis should be of concern to consumers. This partially accounts for the popularity of consumption of the amino sugar glucosamine, in-spite of controversy about its efficacy. We chemically synthesized N-butyryl glucosamine (GlcNBu, which we discovered protected bone and cartilage in an inflammatory arthritis rat model when used as a feed supplement. GlcNBu can also be potentially synthesized biochemically, since we recently demonstrated that human acetyl-CoA: glucosamine-6-phosphate N-acetyltransferase 1 has a relaxed donor specificity and transfers acyl groups of up to four carbons in length, i.e. the butyryl moiety. Oral GlcNBu had no detectable toxicity and also protected against bone loss in ovariectomized (OVX rats as a model for osteoporosis. However, we demonstrated this only for bones excised at 6 months. Thus, the current study aims to determine when bone mineralization is maximized during daily GlcNBu supplementation, in both OVΧ and Sham-OVX rats, in addition to the relationship of bone mineralization to body composition. Methods: Female Sprague-Dawley rats were randomized into 4 groups, containing 8 rats each. The groups consisted of OVX or Sham-OVX rats whose diets were supplemented with either 200 mg/kg/day of GlcNBu or an equimolar amount of glucose. We performed sequential bone density and body composition measurements, by dual-energy X-ray absorptiometry in the live, anesthetised rats, over a 6-month experimental period, starting at the age of 8 weeks. Results were analyzed by descriptive statistics and 2-way ANOVA. Results: The major increases in the mineral content and density of the spine and the femur in GlcNBu-supplemented rats occurred early, from the baseline to week 8. Ovariectomy resulted in a number of significant differences in body composition, while feeding GlcNBu had no significant effects on body composition. The significant effects of

    Xiaoming Bian

    Full Text Available Artificial sweeteners have been widely used in the modern diet, and their observed effects on human health have been inconsistent, with both beneficial and adverse outcomes reported. Obesity and type 2 diabetes have dramatically increased in the U.S. and other countries over the last two decades. Numerous studies have indicated an important role of the gut microbiome in body weight control and glucose metabolism and regulation. Interestingly, the artificial sweetener saccharin could alter gut microbiota and induce glucose intolerance, raising questions about the contribution of artificial sweeteners to the global epidemic of obesity and diabetes. Acesulfame-potassium (Ace-K, a FDA-approved artificial sweetener, is commonly used, but its toxicity data reported to date are considered inadequate. In particular, the functional impact of Ace-K on the gut microbiome is largely unknown. In this study, we explored the effects of Ace-K on the gut microbiome and the changes in fecal metabolic profiles using 16S rRNA sequencing and gas chromatography-mass spectrometry (GC-MS metabolomics. We found that Ace-K consumption perturbed the gut microbiome of CD-1 mice after a 4-week treatment. The observed body weight gain, shifts in the gut bacterial community composition, enrichment of functional bacterial genes related to energy metabolism, and fecal metabolomic changes were highly gender-specific, with differential effects observed for males and females. In particular, ace-K increased body weight gain of male but not female mice. Collectively, our results may provide a novel understanding of the interaction between artificial sweeteners and the gut microbiome, as well as the potential role of this interaction in the development of obesity and the associated chronic inflammation.

    A self-touch paradigm is used to create the illusion that one is touching one's own left elbow when one is actually touching the examiner's arm. Our new self-touch illusion is sensitive to the anatomical structure of the body: you can touch your left elbow with your right index finger but not with your left index finger. Illusion onset was faster and illusion ratings were higher when participants administered touch using the plausible right index finger compared with the implausible left index finger.

  8. A disturbance in sensory processing on the affected side of the body increases limb pain in complex regional pain syndrome.

    Drummond, Peter D; Finch, Philip M

    2014-04-01

    The aim of this study was to determine whether a central disturbance in somatosensory processing contributes to limb pain in complex regional pain syndrome (CRPS). In 37 patients with CRPS, the effect of cooling the ipsilateral forehead on pain in the affected limb was compared with the effect of cooling the contralateral forehead. In addition, symptoms associated with cold-evoked limb pain were explored. Limb pain generally increased when the ipsilateral side of the forehead was cooled but did not change when the contralateral side of the forehead was cooled. Increases were greatest in patients with heightened sensitivity to cold, brushing, and pressure-pain in the ipsilateral forehead, in patients with heightened sensitivity to pressure-pain in the limbs, and in patients with chronic symptoms. In contrast, sensitivity to light touch was diminished in the CRPS-affected limb of patients whose limb pain remained unchanged or decreased during ipsilateral forehead cooling. These preliminary findings suggest that a central disturbance in sensory processing and pain modulation, which extends beyond the affected limb to the ipsilateral forehead, contributes to symptoms in a subgroup of patients with CRPS.

    Ratings of perceived exertion (RPE) are routinely used to monitor, assess, and prescribe aerobic exercise. Heart rate (HR) is another measure used to evaluate exercise intensity. Additionally, affective responses to aerobic exercise have been studied and seem to be influenced by the intensity of the exercise. The perceptual, HR, and affective responses to resistance exercise have not been effectively established. The purpose of this study was to examine whether differences in affect, RPE, and HR exist among college-aged women (n = 31) performing three different modes of resistance training: concentric (CE), eccentric (EE), and traditional concentric/eccentric (TE) performed at varying resistances. The women were asked to complete four sessions of resistance training on variable resistance machines: chest press, seated row, overhead press, and biceps curl. The first session was used to establish the 10-repetition maximum (RM) load for each station. Subsequent sessions involved the execution of training in one of the three test conditions: CE, EE, or TE. The participants performed three sets of each lift at 80% 10-RM, 100% 10-RM, and 120% 10-RM. The data revealed lower RPE during EE than the other test conditions. Similarly, EE elicited more mild HR response than either CE or TE. This finding is potentially important for the establishment of training programs, especially for those individuals recovering from an illness, who had been previously sedentary, and who are involved in rehabilitation of an injury.

    To explore the psychological impact of weight labels. A double-blind experiment that randomly informed participants that they were "normal weight" or "overweight." Public university in Honolulu, Hawai'i. Normal-weight and overweight female undergraduates (N = 113). The Body Image States Scale, Stunkard Rating Scale, Weight Bias Internalization Scale, Positive and Negative Affect Schedule, General Health question from the 12-item Short Form Health Survey, modified version of the Weight Loss Methods Scale, and a manipulation check. A 2 × 2 between-subjects analysis of variance explored the main effects of the assigned weight label and actual weight and interactions between assigned weight label and actual weight. Significant main effects of the assigned weight label emerged on measures of body dissatisfaction, F(1, 109) = 12.40, p = .001, [Formula: see text] = 0.10, internalized weight stigma, F(1, 108) = 4.35, p = .039, [Formula: see text] = .04, and negative affect, F(1, 108) = 9.22, p = .003, [Formula: see text] = .08. Significant assigned weight label × actual weight interactions were found on measures of perceived body image, F(1, 109) = 6.29, p = .014, [Formula: see text] = .06, and perceived health, F(1, 109) = 4.18, p = .043, [Formula: see text] = .04. A weight label of "overweight" may have negative psychological consequences, particularly for overweight women.

    To determine if central serotonin (5-HT)-induced satiety is altered in obesity. Obese and lean Zucker rats received infusion of 5-HT (5 microg/0.5 microl/h) or saline into the ventromedial nucleus of the hypothalamus (VMN) for 2 weeks. In lean rats, 5-HT decreased body weight (7%) and total food intake (15%) which was due to a decreased meal size during the dark phase. In obese rats, a decrease of food intake was also observed in the dark phase, but it was compensated by an increased food intake during the light phase, resulting in no significant changes of total food intake and body weight. In obese rats, meal number but not meal size was affected by 5-HT delivery. Body fat content was not affected by 5-HT in obese rats, while cessation of 5-HT delivery in lean rats resulted in 13% increase. Intra-VMN 5-HT in obese rats did not increase meal-associated satiety as it did in lean rats, but modulated hunger. These results show that the Zucker obese phenotype is characterized by VMN resistance to 5-HT, which may contribute to neurobiological mechanisms of increased meal size and food intake and may diminish anti-obesity effects of serotonergic anorexiants.

    Full Text Available Peak metabolic equivalent (MET is the most reliable indicator of cardiorespiratory fitness (CRF. The aim of this study was to examine the association between CRF indicated by peak MET and body mass index (BMI or fat mass index (FMI in Taiwanese children and adolescents (C-A. Data of 638 C-A aged 10–18 that received symptom-limited treadmill exercise testing was analyzed. Anthropometry-body composition was measured by vector bioelectrical impedance analysis. BMI was defined as body weight (kg/body height (m2 and FMI was defined as fat mass (kg/body height (m2. BMI was grouped by Taiwanese obesity cut-off points. FMI Class-I was categorized by percentage of body fat. FMI Class-II used the reference values from Korean C-A. Excess adiposity was defined as (1 “overweight” and “obesity” by BMI, (2 greater than the sex- and age-specific 75th percentile of whole subjects by FMI Class-I, and (3 greater than 95th percentiles of reference value by FMI Class-II. Boys had significantly higher fat mass and FMI, and had more excess adiposity than girls (all p < 0.05. Both boys and girls with excess adiposity (by any definition had lower MET at anaerobic threshold (AT MET and peak MET (all p < 0.001. BMI and FMI were significantly negatively associated with both AT MET and peak MET significantly (all p < 0.001. FMI (95% CI: −0.411~−0.548 correlated with peak MET more than BMI (95% CI: −0.134~ −0.372 did. Excess adiposity affected CRF negatively. It is concluded that weight management should start early in childhood.

    Dietary protein quality is considered to be dependent on the degree and velocity with which protein is digested, absorbed as amino acids, and retained in the gut as newly synthesized protein. Metabolic animal studies suggest that the quality of soy protein is inferior to that of casein protein, but confirmatory studies in humans are lacking. The study objective was to assess the quality of casein and soy protein by comparing their metabolic effects in healthy human subjects. Whole-body protein kinetics, splanchnic leucine extraction, and urea production rates were measured in the postabsorptive state and during 8-h enteral intakes of isonitrogenous [0.42 g protein/(kg body weight . 8 h)] protein-based test meals, which contained either casein (CAPM; n = 12) or soy protein (SOPM; n = 10) in 2 separate groups. Stable isotope techniques were used to study metabolic effects. With enteral food intake, protein metabolism changed from net protein breakdown to net protein synthesis. Net protein synthesis was greater in the CAPM group than in the SOPM group [52 +/- 14 and 17 +/- 14 nmol/(kg fat-free mass (FFM) . min), respectively; P CAPM (P = 0.07). Absolute splanchnic extraction of leucine was higher in the subjects that consumed CAPM [306 +/- 31 nmol/(kg FFM . min)] vs. those that consumed SOPM [235 +/- 29 nmol/(kg FFM . min); P < 0.01]. In conclusion, a significantly larger portion of soy protein is degraded to urea, whereas casein protein likely contributes to splanchnic utilization (probably protein synthesis) to a greater extent. The biological value of soy protein must be considered inferior to that of casein protein in humans.

    Increasing numbers of people are running with their dogs, particularly in harness through the sport canicross. Whilst canicross races are typically held in the winter months, some human centred events are encouraging running with dogs in summer months, potentially putting dogs at risk of heat related injuries, including heatstroke. The aim of this project was to investigate the effects of ambient conditions and running speed on post-race temperature of canicross dogs in the UK, and investigate the potential risk of heatstroke to canicross racing dogs. The effects of canine characteristics (e.g. gender, coat colour) were explored in order to identify factors that could increase the risk of exercise-induced hyperthermia (defined as body temperature exceeding the upper normal limit of 38.8°C).108 dogs were recruited from 10 race days, where ambient conditions ranged from - 5 to 11°C measured as universal thermal comfort index (UTCI). 281 post race tympanic membrane temperatures were recorded, ranging from 37.0-42.5°C. There was a weak correlation between speed and post-race temperature (r = 0.269, P coated dogs (χ(2) = 8.234, P = 0.014), were significantly more likely to finish the race with a temperature exceeding 40.6°C. Prolonged elevati°n of body temperature above this temperature is likely to cause heatstroke. At every race dogs exceeded this critical temperature, with 10.7% (n = 30) of the overall study population exceeding this temperature throughout the study period. The results suggest male dogs, dark coloured dogs, and increased speed of running all increase the risk of heatstroke in racing canicross dogs. Further research is required to investigate the impact of environmental conditions on post-race cooling, to better understand safe running conditions for dogs. Copyright © 2017 Elsevier Ltd.

    The use of surface electromyography (sEMG) to evaluate muscle activation when executing whole body vibration exercises (WBVE) in studies provide neuromuscular findings, in healthy and diseased populations. Perform a systematic review of the effects of WBVE by sEMG of lower limbs in non-healthy populations. The search using the defined keywords was performed in PubMed, PEDRo and EMBASE databases by three independent researchers. Applying the PRISMA statement several studies were selected according to eligibility criteria and organized for the review. Full papers were included if they described effects of WBVE for the treatment of illnesses, evaluated by sEMG of lower limbs independently on the year of the publication; in comparison or associated with other treatment and evaluation techniques. Seven publications were selected; two in spinal cord injury patients, one in Friedreich's ataxia patients, three in stroke patients and one study in breast cancer survivors. Reported effects of WBV in were muscle activation by sEMG and also on strength, blood flow and exercise resistance; even in paretic limbs. By the use of sEMG it was verified that WBVE elicits muscle activation in diseased population. These results may lead to the definition of exercise protocols to maintain or increase muscular activation. However, due to the heterogeneity of methods among studies, there is currently no consensus on the sEMG signal processing. These strategies might also induce effects on muscle strength, balance and flexibility in these and other illnesses.

    Background: Holder pasteurization (HP) destroys multiple bioactive factors in donor human milk (DM), and UV-C irradiation (UVC) is potentially a gentler method for pasteurizing DM for preterm infants. Objective: We investigated whether UVC-treated DM improves gut maturation and resistance toward bacterial infections relative to HP-treated DM. Methods: Bacteria, selected bioactive components, and markers of antioxidant capacity were measured in unpasteurized donor milk (UP), HP-treated milk, and UVC-treated milk (all from the same DM pool). Fifty-seven cesarean-delivered preterm pigs (91% gestation; ratio of males to females, 30:27) received decreasing volumes of parental nutrition (average 69 mL · kg -1 · d -1 ) and increasing volumes of the 3 DM diets ( n = 19 each, average 89 mL · kg -1 · d -1 ) for 8-9 d. Body growth, gut structure and function, and systemic bacterial infection were evaluated. Results: A high bacterial load in the UP (6×10 5 colony forming units/mL) was eliminated similarly by HP and UVC treatments. Relative to HP-treated milk, both UVC-treated milk and UP showed greater activities of lipase and alkaline phosphatase and concentrations of lactoferrin, secretory immunoglobulin A, xanthine dehydrogenase, and some antioxidant markers (all P bacterial cultures in the bone marrow (28%) than pigs fed HP-treated milk (68%) ( P resistance against bacterial infections as shown in preterm pigs as a model for DM-fed preterm infants. © 2017 American Society for Nutrition.

    Seasonal changes in temperature and photoperiod are important environmental cues used by small birds to adjust their body mass ( M b ) and thermogenesis. However, the relative importance of these cues with respect to seasonal adjustments in M b and thermogenesis is difficult to distinguish. In particular, the effects of temperature and photoperiod on energy metabolism and thermoregulation are not well known in many passerines. To address this problem, we measured the effects of temperature and photoperiod on M b , energy intake, resting metabolic rate (RMR), organ mass and physiological and biochemical markers of metabolic activity in the Chinese bulbul ( Pycnonotus sinensis ). Groups of Chinese bulbuls were acclimated in a laboratory to the following conditions: (1) warm and long photoperiod, (2) warm and short photoperiod, (3) cold and long photoperiod, and (4) cold and short photoperiod, for 4 weeks. The results indicate that Chinese bulbuls exhibit adaptive physiological regulation when exposed to different temperatures and photoperiods. M b , RMR, gross energy intake and digestible energy intake were higher in cold-acclimated than in warm-acclimated bulbuls, and in the short photoperiod than in the long photoperiod. The resultant flexibility in energy intake and RMR allows Chinese bulbuls exposed to different temperatures and photoperiods to adjust their energy balance and thermogenesis accordingly. Cold-acclimated birds had heightened state-4 respiration and cytochrome c oxidase activity in their liver and muscle tissue compared with warm-acclimated birds indicating the cellular mechanisms underlying their adaptive thermogenesis. Temperature appears to be a primary cue for adjusting energy budget and thermogenic ability in Chinese bulbuls; photoperiod appears to intensify temperature-induced changes in energy metabolism and thermoregulation. © 2017.

    Full Text Available Only few studies in the plant tissue culture literature have examined the impact of lanthanoids, or rare earth elements, on in vitro plant organogenesis. In this study, using a model plant, hybrid Cymbidium Twilight Moon ‘Day Light’, the impact of six lanthanoids (lanthanum (III nitrate hexahydrate (La(NO33 · 6H2O, cerium (III nitrate hexahydrate (Ce(NO33 · 6H2O, neodymium (III nitrate hexahydrate (Nd(NO33 · 6H2O, praseodymium (III nitrate hexahydrate (Pr(NO33 · 6H2O, samarium (III nitrate hexahydrate (Sm(NO33 · 6H2O, gadolinium (III nitrate hexahydrate (Gd(NO33 · 6H2O on new protocorm-like body (neo-PLB formation on Teixeira Cymbidium (TC medium was examined. 0 (control, 1, 2, 4 and 8 mg·dm-3 of each lanthanoid was tested. All lanthanoids could produce more neo-PLBs and neo-PLB fresh weight than TC medium lacking plant growth regulators (PGRs, suggesting some PGR-like ability of lanthanoids, although PLB-related traits (percentage of half-PLBs forming neo-PLBs; number of neo-PLBs formed per half-PLB; fresh weight of half-PLB + neo-PLBs was always significantly lower than TC medium containing PGRs. Except for Gd, all other lanthanoids had no negative impact on the number of new leaves from neo-PLB-derived shoots, but all lanthanoids showed a significantly lower plant height, shoot fresh weight and shoot dry weight and, in most cases, SPAD (chlorophyll content value. In addition, using the same concentration of the six lanthanoids, the ability to fortify root formation of neo-PLB-derived plantlets was also assessed. Except for Sm, all other lanthanoids significantly increased the number of roots, root fresh and dry weight.

    To analyze the transcriptomic profile of endometrial gene alterations during the window of implantation in infertile obese patients. Multicenter, prospective, case-control study. Three academic medical centers for reproductive medicine. Infertile patients, stratified into body mass index (BMI) categories according to the World Health Organization guidelines, were included in the study. Endometrial samples were obtained from women undergoing standardized estrogen and P replacement cycles after 5 days of vaginal P supplementation. To identify endometrial gene expression alterations that occur during the window of implantation in infertile obese patients as compared with infertile normal-weight controls using a microarray analysis. XCL1, XCL2, HMHA1, S100A1, KLRC1, COTL1, COL16A1, KRT7, and MFAP5 are significantly dysregulated during the window of implantation in the receptive endometrium of obese patients. COL16A1, COTL1, HMHA1, KRCL1, XCL1, and XCL2 were down-regulated and KRT7, MFAP5, and S100A1 were up-regulated in the endometrium of obese patients. These genes are mainly involved in chemokine, cytokine, and immune system activity and in the structural extracellular matrix and protein-binding molecular functions. Obesity is associated with significant endometrial transcriptomic differences as compared with non-obese subjects. Altered endometrial gene expression in obese patients may contribute to the lower implantation rates and increased miscarriage rates seen in obese infertile patients. NCT02205866.

    To our knowledge, there are nine previous reports of patients with congenital scrotal agenesis (CSA), seven of which were bilateral, and unilateral in two, also named as hemiscrotal agenesis (HSA). Here, we report a male infant with the previously undescribed co-occurrence of HSA with cutis marmorata telangiectatica congenita (CMTC), and hydronephrosis due to vesicoureteral reflux, all of them on the left side. CMTC is a segmental vascular malformation usually attributed to mosaicism of a postzygotic mutation, whereas the mechanisms in the CSA involve a failure on the labioscrotal fold (LSF) development due to a localized 5α-reductase deficiency and/or androgen insensitivity. Since the skin with HSA was affected also by CMTC and by the fact that it exhibited lack of response to the topical testosterone treatment, all this suggests to us an androgen insensitivity mosaicism in our patient restricted to the left LSF, because skin with intact androgen receptors normally shows some type of response. Since CSA and/or HSA have been also seen in patients with PHACES, popitleal pterygium syndrome, or as part of a recently proposed familial entity with CSA (or agenesis of labia majora as its female counterpart), developmental delay, visual impairment, and moderate hearing loss, further reports could confirm this manifest genetic heterogeneity, highly evocative of somatic mosaicism in our patient. © 2013 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The development of male- or female-specific phenotypes in squamates is typically controlled by either temperature-dependent sex determination (TSD or chromosome-based genetic sex determination (GSD. However, while sex determination is a major switch in individual phenotypic development, it is unknownhow evolutionary transitions between GSD and TSD might impact on the evolution of squamate phenotypes, particularly the fast-evolving and diverse genitalia. Here, we take the unique opportunity of studying the impact of both sex determination mechanisms on the embryological development of the central bearded dragon (Pogona vitticeps. This is possible because of the transitional sex determination system of this species, in which genetically male individuals reverse sex at high incubation temperatures. This can trigger the evolutionary transition of GSD to TSD in a single generation, making P. vitticeps an ideal model organism for comparing the effects of both sex determination processes in the same species. Results We conducted four incubation experiments on 265 P. vitticeps eggs, covering two temperature regimes (“normal” at 28 °C and “sex reversing” at 36 °C and the two maternal sexual genotypes (concordant ZW females or sex-reversed ZZ females. From this, we provide the first detailed staging system for the species, with a focus on genital and limb development. This was augmented by a new sex chromosome identification methodology for P. vitticeps that is non-destructive to the embryo. We found a strong correlation between embryo age and embryo stage. Aside from faster growth in 36 °C treatments, body and external genital development was entirely unperturbed by temperature, sex reversal or maternal sexual genotype. Unexpectedly, all females developed hemipenes (the genital phenotype of adult male P. vitticeps, which regress close to hatching. Conclusions The tight correlation between embryo age and embryo stage

    Due to the high cost of conducting field measurements, questionnaires are usually preferred for the assessment of physical workloads and musculoskeletal disorders (MSDs). This study compares the physical workloads of whole-body vibration (WBV) and awkward postures by direct field measurements and self-reported data of 45 occupational drivers. Manual materials handling (MMH) and MSDs were also investigated to analyse their effect on drivers' perception. Although the measured values for WBV exposure were very similarly distributed among the drivers, the subjects' perception differed significantly. Concerning posture, subjects seemed to estimate much better when the difference in exposure was significantly large. The percentage of measured awkward trunk and head inclination were significantly higher for WBV-overestimating subjects than non-overestimators; 77 and 80% vs. 36 and 33%. Health complaints in terms of thoracic spine, cervical spine and shoulder-arm were also significantly more reported by WBV-overestimating subjects (42, 67, 50% vs. 0, 25, 13%, respectively). Although more MMH was reported by WBV-overestimating subjects, there was no statistical significance in this study. Self-reported exposures of occupational drivers are affected by many other cofactors, and this can result in misinterpretations. A comparison between field measurement and questionnaire was used to highlight the factors affecting the perception of drivers for whole-body vibration (WBV) exposure. Posture and musculoskeletal disorders influenced the perception of the similarly WBV-exposed drivers significantly.

    Functional hypercortisolism (FH) is a condition which occurs in some clinical states, such as major depression, eating disorders, numerous psychiatric conditions, and diabetes mellitus (DM) and which exerts several negative systemic effects. No data exist on the potentially harmful role of FH on body composition. In this retrospective study, we evaluated the influence of hypothalamic-pituitary-adrenal (HPA) axis dysregulation on body composition in men affected by DM-associated late-onset hypogonadism (LOH). Fourteen subjects affected by FH (FH-LOH) and 18 subjects not affected (N-LOH) were studied. Clinical, hormonal, and body composition measures were considered. The 2 groups had comparable age and weight. FH-LOH patients had lower levels of total (2 ± 0.27 ng/mL versus 2.31 ± 0.26 ng/mL; P = .003) and free (39.5 ± 6.44 pg/mL versus 46.8 ± 7.23 pg/mL; P = .005) (median, 38.7 [interquartile range, 36.1 to 41.3] pg/mL versus median, 46.1 [interquartile range, 40.4 to 52.7] pg/mL) testosterone compared to N-LOH patients. Abdominal fat amount was greater in FH-LOH than in N-LOH patients, even after adjustment for total testosterone. None of the bivariate correlations between body composition measures and hormonal variables were significant in N-LOH. Conversely, in FH-LOH, cortisol area under the curve (AUC) was found to be positively and significantly correlated with trunk (r = 0.933; P<.001) and abdominal fat (r = 0.852; P<.001) and negatively with lean leg (r = -0.607; P = .021). All of these associations were further confirmed upon linear regression analysis in FH-LOH (respectively, unstandardized β = 10.988 [P<.001]; β = 1.156 [P<.001]; β = -7.675 [P = .021]). Multivariate regression analysis confirmed AUC cortisol as a predictor of trunk and abdominal fat in FH-LOH. Dysregulation of the HPA axis in LOH-associated DM seems to be involved in abdominal fat accumulation.

    Sarcopenic obesity (SO) is a geriatric syndrome characterized by the disproportion between the amount of lean mass and fat mass. Exercise decreases fat and maintains muscle mass; however, older people fail to exercise at doses sufficient to affect musculoskeletal and cardiometabolic risk factors. The aim of this study was to evaluate the effect of whole-body electromyostimulation (WB-EMS), a time-efficient, joint-friendly and highly individualized exercise technology, on sarcopenia and SO in older men. A total of 100 community-dwelling northern Bavarian men aged ≥70 years with sarcopenia and obesity were randomly (1-1-1) assigned to either 16 weeks of 1) WB-EMS and protein supplementation (WB-EMS&P), 2) isolated protein supplementation or 3) nonintervention control. WB-EMS consisted of 1.5×20 min (85 Hz, 350 µs, 4 s of strain to 4 s of rest) applied with moderate-to-high intensity while moving. We further generated a daily protein intake of 1.7-1.8 g/kg/body mass per day. The primary study end point was Sarcopenia Z-Score, and the secondary study end points were body fat rate (%), skeletal muscle mass index (SMI) and handgrip strength. Intention-to-treat analysis determined a significantly favorable effect of WB-EMS&P ( P men. However, the suboptimum effect on functional parameters should be addressed by increased voluntary activation during WB-EMS application.

    Little is known about the effect of androgen receptor (AR) gene CAG repeat polymorphism in conditioning body composition changes after testosterone replacement therapy (TRT). In this study, we aimed to clarify this aspect by focussing our attention on male post-surgical hypogonadotropic hypogonadism, a condition often associated with partial or total hypopituitarism. Fourteen men affected by post-surgical hypogonadotropic hypogonadism and undergoing several replacement hormone therapies were evaluated before and after TRT. Dual-energy X-ray absorptiometry (DEXA)-derived body composition measurements, pituitary-dependent hormones and AR gene CAG repeat polymorphism were considered. While testosterone and insulin-like growth factor-1 (IGF-1) levels increased after TRT, cortisol concentration decreased. No anthropometric or body composition parameters varied significantly, except for abdominal fat decrease. The number of CAG triplets was positively and significantly correlated with this abdominal fat decrease, while the opposite occurred between the latter and Δ-testosterone. No correlation of IGF-1 or cortisol variation (Δ-) with Δ-abdominal fat was found. At multiple linear regression, after correction for Δ-testosterone, the positive association between CAG triplet number and abdominal fat change was confirmed. In male post-surgical hypogonadotropic hypogonadism, shorter length of AR CAG repeat tract is independently associated with a more marked decrease of abdominal fat after TRT.

    Human sleeping quarters (domiciles) and chicken coops are key source habitats of Triatoma infestans-the principal vector of the infection that causes Chagas disease-in rural communities in northern Argentina. Here we investigated the links among individual bug bloodmeal contents (BMC, mg), female fecundity, body length (L, mm), host blood sources and habitats. We tested whether L, habitat and host blood conferred relative fitness advantages using generalized linear mixed-effects models and a multimodel inference approach with model averaging. The data analyzed include 769 late-stage triatomines collected in 120 sites from six habitats in 87 houses in Figueroa, Santiago del Estero, during austral spring. L correlated positively with other body-size surrogates and was modified by habitat type, bug stage and recent feeding. Bugs from chicken coops were significantly larger than pig-corral and kitchen bugs. The best-fitting model of log BMC included habitat, a recent feeding, bug stage, log Lc (mean-centered log L) and all two-way interactions including log Lc. Human- and chicken-fed bugs had significantly larger BMC than bugs fed on other hosts whereas goat-fed bugs ranked last, in consistency with average blood-feeding rates. Fecundity was maximal in chicken-fed bugs from chicken coops, submaximal in human- and pig-fed bugs, and minimal in goat-fed bugs. This study is the first to reveal the allometric effects of body-size surrogates on BMC and female fecundity in a large set of triatomine populations occupying multiple habitats, and discloses the links between body size, microsite temperatures and various fitness components that affect the risks of transmission of Trypanosoma cruzi.

    Adenosine-5'-triphosphate (ATP) is primarily known as a cellular source of energy. Increased ATP levels may have the potential to enhance body composition. A novel, proprietary blend of ancient peat and apple extracts has been reported to increase ATP levels, potentially by enhancing mitochondrial ATP production. Therefore, the purpose of this investigation was to determine the supplement's effects on body composition when consumed during 12 weeks of resistance training. Twenty-five healthy, resistance-trained, male subjects (age, 27.7 ± 4.8 years; height, 176.0 ± 6.5 cm; body mass, 83.2 ± 12.1 kg) completed this study. Subjects supplemented once daily with either 1 serving (150 mg) of a proprietary blend of ancient peat and apple extracts (TRT) or placebo (PLA). Supervised resistance training consisted of 8 weeks of daily undulating periodized training followed by a 2-week overreach and a 2-week taper phase. Body composition was assessed using dual-energy X-ray absorptiometry and ultrasound at weeks 0, 4, 8, 10, and 12. Vital signs and blood markers were assessed at weeks 0, 8, and 12. Significant group × time (p < 0.05) interactions were present for ultrasound-determined cross-sectional area, which increased in TRT (+0.91 cm(2)) versus PLA (-0.08 cm(2)), as well as muscle thickness (TRT: +0.46; PLA: +0.04 cm). A significant group × time (p < 0.05) interaction existed for creatinine (TRT: +0.06; PLA: +0.15 mg/dL), triglycerides (TRT: +24.1; PLA: -20.2 mg/dL), and very-low-density lipoprotein (TRT: +4.9; PLA: -3.9 mg/dL), which remained within clinical ranges. Supplementation with a proprietary blend of ancient peat and apple extracts may enhance resistance training-induced skeletal muscle hypertrophy without affecting fat mass or blood chemistry in healthy males.

    Guidelines for suggested intake of ω-3 polyunsaturated fatty acids (PUFAs) are limited in youth and rely primarily on age. However, body weight varies considerably within age classifications. The current analyses examined effects of body weight and body mass index (BMI) on fatty acid accumulation in 64 youth (7-14 years) with a diagnosed mood disorder in a double-blind randomized-controlled trial (2000mg ω-3 supplements or a control capsule) across 12 weeks. Weight and height were measured at the first study visit and EPA and DHA levels were determined using fasting blood samples obtained at both the first and end-of-study visits. In the ω-3 supplementation group, higher baseline body weight predicted less plasma accumulation of both EPA [B = -0.047, (95% CI = -0.077; -0.017), β = -0.54, p = 0.003] and DHA [B = -0.02, (95% CI = -0.034; -0.007), β = -0.52, p = 0.004]. Similarly, higher BMI percentile as well as BMI category (underweight, normal weight, overweight/obese) predicted less accumulation of EPA and DHA (ps≤0.01). Adherence to supplementation was negatively correlated with BMI percentile [B = -0.002 (95% CI = -0.004; 0.00), β = -0.44, p = 0.019], but did not meaningfully affect observed associations. As intended, the control supplement exerted no significant effect on plasma levels of relevant fatty acids regardless of youth body parameters. These data show strong linear relationships of both absolute body weight and BMI percentile with ω-3 PUFA accumulation in youth. A dose-response effect was observed across the BMI spectrum. Given increasing variability in weight within BMI percentile ranges as youth age, dosing based on absolute weight should be considered. Moreover, effects of weight should be incorporated into statistical models in studies examining clinical effects of ω-3 PUFAs in youth as well as adults, as weight-related differences in effects may contribute meaningfully to inconsistencies in the current literature.

    To examine the indirect effect of body mass index z-score (BMIz) on health-related quality of life (HRQOL) through disordered eating attitudes and behaviors in a community sample of preadolescent children, and the degree to which negative affect moderated the association between BMIz and disordered eating attitudes and behaviors. Participants included 165 children between 8 and 12 years of age (M = 9.41). HRQOL, disordered eating attitudes and behaviors, and negative affect were assessed using self-report measures. Height and weight were collected by research staff. Consistent with previous research in treatment-seeking and adolescent samples, the indirect effect of BMIz on HRQOL through disordered eating attitudes and behaviors was significant. Negative affect did not moderate the relationship between BMIz and disordered eating attitudes and behaviors. Intervening on disordered eating attitudes and behaviors in preadolescents with higher weight status is critical to prevent the risk for poor HRQOL. © The Author 2016.

    Some human diseases, including obesity, Type II diabetes, and numerous cancers, are thought to be influenced by environments experienced in early life, including in utero. Maternal diet during the perinatal period may be especially important for adult offspring energy balance, potentially affecting both body composition and physical activity. This effect may be mediated by the genetic background of individuals, including, for example, potential "protective" mechanisms for individuals with inherently high levels of physical activity or high basal metabolic rates. To examine some of the genetic and environmental factors that influence adult activity levels, we used an ongoing selection experiment with 4 replicate lines of mice bred for high voluntary wheel running (HR) and 4 replicate, non-selected control lines (C). Dams (half HR and half C) were fed a "Western" diet (WD, high in fat and sucrose) or a standard diet (SD) from 2weeks prior to mating until their pups could feed on solid food (14days of age). We analyzed dam and litter characteristics from birth to weaning, and offspring mass and physical activity into adulthood. One male offspring from each litter received additional metabolic and behavioral tests. Maternal WD caused pups to eat solid food significantly earlier for C litters, but not for HR litters (interaction of maternal environment and genotype). With dam mass as a covariate, mean pup mass was increased by maternal WD but litter size was unaffected. HR dams had larger litters and tended to have smaller pups than C dams. Home-cage activity of juvenile focal males was increased by maternal WD. Juvenile lean mass, fat mass, and fat percent were also increased by maternal WD, but food consumption (with body mass as a covariate) was unaffected (measured only for focal males). Behavior in an elevated plus maze, often used to indicate anxiety, was unaffected by maternal WD. Maximal aerobic capacity (VO 2 max) was also unaffected by maternal WD, but HR had

    The use and partition of feed energy are key elements in productive efficiency of pigs. This study aimed to determine whether dietary energy sources affect the partition of body lipids and tissue biochemical pathways of energy use between pigs differing in feed efficiency. Forty-eight barrows (pure Large White) from two divergent lines selected for residual feed intake (RFI), a measure of feed efficiency, were compared. From 74 d to 132 ± 0.5 d of age, pigs (n = 12 by line and by diet) were offered diets with equal protein and ME contents. A low fat, low fiber diet (LF) based on cereals and a high fat, high fiber diet (HF) where vegetal oils and wheat straw were used to partially substitute cereals, were compared. Irrespective of diet, gain to feed was 10% better (P Lipid contents in backfat and LM also declined (-5% and -19%, respectively; P lipid content was greater (P lipid and glucose storage in tissues.

    To examine whether a preoperative cognitive behavioural therapy (CBT) intervention exceeds usual care in the improvements of dysfunctional eating behaviours, mood, affective symptoms and body weight 1 year after bariatric surgery. This is a 1-year follow-up of a single centre parallel-group randomised controlled trial ( http://clinicaltrials.gov/ct2/show/NCT01403558). A total of 80 (55 females) patients mean (SD) age 44 (10) years were included. The intervention group received 10 weeks of CBT prior to bariatric surgery, and the control group received nutritional support and education. Both groups were assessed at baseline (T0), post CBT intervention/preoperatively (T1), and 1 year postoperatively (T2). Using a mixed modelling statistical approach, we examined if the CBT group improved more across time than the control group. Our hypothesis was not supported as both groups had comparable improvements in all outcomes except for anxiety symptoms. Body weight declined by 30.2 % (37.3 kg) in the CBT group and by 31.2 % (40.0 kg) in the control group from baseline to follow-up, p = 0.82. There were statistically significant reductions in anxiety and depression symptoms in the CBT group between T0 and T1 and between T1 and T2 for depression only. However, in the control group, the anxiety score did not change significantly. The CBT group showed an earlier onset of improvements in all eating behaviours and affective symptoms than the control group. The 10-week CBT intervention showed beneficial effects preoperatively, but the non-significant group differences postoperatively indicate a genuine effect of surgery.

    Full Text Available Dietary protein digestion and amino acid absorption kinetics determine the post-prandial muscle protein synthetic response. Body position may affect gastrointestinal function and modulate the post-prandial rise in plasma amino acid availability. We aimed to assess the impact of body position on gastric emptying rate and the post-prandial rise in plasma amino acid concentrations following ingestion of a single, meal-like amount of protein. In a randomized, cross-over design, eight healthy males (25 ± 2 years, 23.9 ± 0.8 kg·m−2 ingested 22 g protein and 1.5 g paracetamol (acetaminophen in an upright seated position (control and in a −20° head-down tilted position (inversion. Blood samples were collected during a 240-min post-prandial period and analyzed for paracetamol and plasma amino acid concentrations to assess gastric emptying rate and post-prandial amino acid availability, respectively. Peak plasma leucine concentrations were lower in the inversion compared with the control treatment (177 ± 15 vs. 236 ± 15 mmol·L−1, p < 0.05, which was accompanied by a lower plasma essential amino acid (EAA response over 240 min (31,956 ± 6441 vs. 50,351 ± 4015 AU; p < 0.05. Peak plasma paracetamol concentrations were lower in the inversion vs. control treatment (5.8 ± 1.1 vs. 10.0 ± 0.6 mg·L−1, p < 0.05. Gastric emptying rate and post-prandial plasma amino acid availability are significantly decreased after protein ingestion in a head-down tilted position. Therefore, upright body positioning should be considered when aiming to augment post-prandial muscle protein accretion in both health and disease.

    Leucine is suggested to act as nutrient signal of high-protein diets regulating pathways associated with an alleviation of metabolic syndrome parameters. However, the subject remains controversial. The aim of this study was to assess and to compare the effects of high-protein diets with dietary leucine supplementation in mice, particularly on energy homeostasis, body composition, and expression of uncoupling protein (UCP), which are suggested to decrease food energy efficiency. Male C57BL/6 mice were exposed for 14 weeks to semi-synthetic diets containing either 20% (adequate protein content, AP) or 50% whey protein (high-protein content, HP). A third group was fed the AP diet supplemented with L-leucine (AP + L) corresponding to the leucine content of the HP diet. The total fat content was 5% (w/w). Body weight gain, body composition, energy expenditure, and protein expression of UCP1 in brown adipose tissue, and UCP3 in skeletal muscle were not different between groups. In HP-fed mice, a stronger increase in blood glucose levels was detected during glucose tolerance tests compared to AP and AP + L, whereas plasma insulin was similar in all groups. Leucine supplementation did not affect glucose tolerance. Plasma cholesterol was significantly decreased in HP and AP + L when compared to AP. Plasma triglyceride concentrations were increased twofold in HP-fed mice when compared to AP + L and AP groups. Liver and skeletal muscle triglyceride and glycogen concentrations were similar in all groups. Postabsorptive plasma concentrations of branched-chain amino acids were not significantly increased after exposure to HP and AP + L diets, whereas those of lysine were decreased in HP and AP + L mice when compared to AP (P supplementation has no significant effect on energy homeostasis and UCP expression compared with AP diets when feeding a low-fat diet. The use of high-quality whey protein might at least in part explain the results obtained.

    Horse reproduction tends to be seasonal. The main adjusting factor in their original temperate ranges is photoperiod variation, although it is absent in equatorial areas where horses were introduced by European colonizers. Hence, dates of reproduction in these areas may be influenced by factors affecting mares' conditions and the success of foaling. Here we study reproductive timing in Creole horses in Ecuador reared in an extensive production system. We found that foaling peaked in August. Mares' conditions showed one peak in June-July, before the start of the breeding season, and another in December, and it was highly variable along the year. Mares' conditions increased after a period of vegetation growth and thus appeared negatively associated with the increment of grass greenness (normalized difference vegetation index data). Seasonal flooding of some pasturelands during March and April appeared to seriously impair mares' conditions and probably influenced the timing of foaling toward the dry season. Our results evidenced that horse breeding in these equatorial areas tended to be seasonal and point to some key factors that influence phenology by affecting body condition of mares, which may have implications for horse biology and management. © 2017 Japanese Society of Animal Science.

    Beef production from cull cows is an additional source of income for dairy farms and greatly contributes to red meat production, but the sources of variation of live animal characteristics and the carcass traits of cull cows have rarely been examined. This study investigated the effects of the farm type, breed, age at slaughter (AGE) and calving to culling interval (Calv_Cull) on the body traits and carcass characteristics of dairy and dual-purpose cull cows. Data from 555 cull cows from 182 herds belonging to five farm types, characterised by a combination of housing and feeding systems, were recorded and analysed. Dairy breeds, such as Holstein Friesian and Brown Swiss, and dual-purpose breeds (Simmental, Rendena) were included in the trait assessments. The day before slaughter, the cows were weighed and scored for body condition (BCS) and fleshiness, and then, their heart girth and wither height were measured. At the slaughterhouse, the carcass weight (CW), dressing percentage (DP), carcass conformation and fatness scores, carcass price per kg and carcass total value were obtained. On average, the cows were slaughtered at nearly 71±27 months of age, 285±187 days after the last calving; 615±95 kg BW; and provided a 257±51 kg CW. Nearly 50% of the cows fell within the BCS range of 2.75 to 3.50, and the carcasses were mostly graded in the lowest class of conformation and fatness scores. Cull cows from free-stall farms had a higher DP, carcass conformation score and price than those from traditional tie-stall farms. The breed influenced the AGE, live animal characteristics and carcass traits. Cows from dairy breeds were younger at slaughter, had a lower BCS and fleshiness, and greater body measurements, but a lower DP and carcass price than those from dual-purpose breeds, although differences between the breeds were found within both groups. The age of the cows at slaughter influenced the Calv_Cull and increased the BW, body measurements and CW, but not the

    Signaling peptides produced in peripheral tissues such as gut, adipose tissue, and pancreas communicate with brain centers, such as hypothalamus and hindbrain to manage energy homeostasis. These regulatory mechanisms of energy intake and storage have evolved during long periods of hunger in the evolution of man to protect the species from extinction. It is now clear that these circuitries are influenced by prenatal and postnatal environmental factors including endocrine disruptive chemicals. Hypothalamic appetite regulatory systems develop and mature in utero and early infancy, and involve signaling pathways that are important also for the regulation of puberty onset. Recent studies in humans and animals have shown that metabolic pathways involved in regulation of growth, body weight gain and sexual maturation are largely affected by epigenetic programming that can impact both current and future generations. In particular, intrauterine and early infantile developmental phases of high plasticity are susceptible to factors that affect metabolic programming that therefore, affect metabolic function throughout life. In children born small for gestational age, poor nutritional conditions during gestation can modify metabolic systems to adapt to expectations of chronic undernutrition. These children are potentially poorly equipped to cope with energy-dense diets and are possibly programmed to store as much energy as possible, leading to later obesity, metabolic syndrome, disturbed regulation of normal puberty and early onset of cardiovascular disease. Most cases of disturbed energy balance are likely a result of a combination of genetics, epigenetics and environment. This review will discuss potential mechanisms linking intrauterine growth retardation with changes in growth, energy homeostasis and sexual maturation.

    To correlate hemostatic parameters with clinical markers of fat distribution and laboratory variables in women with polycystic ovary syndrome (PCOS) compared with healthy control subjects. Cross-sectional study. Tertiary teaching hospital. Forty-five women with PCOS and 45 control women matched for age and body mass index (BMI). Clinical evaluation and venipuncture. Age, BMI, waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), Ferriman-Gallwey index, fasting glucose, fasting insulin, total testosterone, free testosterone (FT), thrombin-activatable fibrinolysis inhibitor (TAFI), D-dimer, plasminogen activator inhibitor (PAI) 1, and the parameters of thrombin generation test (TGT), including the lag time (Tlag), time to peak thrombin generation (Tmax), peak concentration (Cmax), and the area under the thrombin generation curve (TAUC). In the PCOS group, BMI and WC correlated positively with TAFI, D-dimer, PAI-1, Cmax, and TAUC; HC with D-dimer and PAI-1; WHR with TAFI, D-dimer, and PAI-1; glucose with TAFI; insulin and homeostasis-model assessment of insulin resistance with PAI-1; and FT with Cmax and TAUC. Age correlated positively with D-dimer and PAI-1, and negatively with Tlag and Tmax. In the control group, there were no correlations between clinical markers of fat distribution and hemostatic parameters, but age and fasting glucose correlated positively with PAI-1, and FT with Tmax and TAUC. In PCOS, android body fat distribution may directly affect hemostatic parameters, particularly in young and overweight women. Further studies are needed to establish a correlation between these results and an increase in thromboembolic risk. Copyright © 2015 American Society for Reproductive Medicine.

    Fillet yield (FY, %) is an economically-important trait in rainbow trout aquaculture that affects production efficiency. Despite that, FY has received little attention in breeding programs because it is difficult to measure on a large number of fish and cannot be directly measured on breeding candidates. The recent development of a high-density SNP array for rainbow trout has provided the needed tool for studying the underlying genetic architecture of this trait. A genome-wide association study (GWAS) was conducted for FY, body weight at 10 (BW10) and 13 (BW13) months post-hatching, head-off carcass weight (CAR), and fillet weight (FW) in a pedigreed rainbow trout population selectively bred for improved growth performance. The GWAS analysis was performed using the weighted single-step GBLUP method (wssGWAS). Phenotypic records of 1447 fish (1.5 kg at harvest) from 299 full-sib families in three successive generations, of which 875 fish from 196 full-sib families were genotyped, were used in the GWAS analysis. A total of 38,107 polymorphic SNPs were analyzed in a univariate model with hatch year and harvest group as fixed effects, harvest weight as a continuous covariate, and animal and common environment as random effects. A new linkage map was developed to create windows of 20 adjacent SNPs for use in the GWAS. The two windows with largest effect for FY and FW were located on chromosome Omy9 and explained only 1.0-1.5% of genetic variance, thus suggesting a polygenic architecture affected by multiple loci with small effects in this population. One window on Omy5 explained 1.4 and 1.0% of the genetic variance for BW10 and BW13, respectively. Three windows located on Omy27, Omy17, and Omy9 (same window detected for FY) explained 1.7, 1.7, and 1.0%, respectively, of genetic variance for CAR. Among the detected 100 SNPs, 55% were located directly in genes (intron and exons). Nucleotide sequences of intragenic SNPs were blasted to the Mus musculus genome to create a

    Few studies have evaluated the accuracy of ultrasonography in detecting steatosis in patients with chronic hepatitis C. We assessed its accuracy in detecting steatosis and factors that affect its diagnostic performance in consecutive patients with chronic hepatitis C virus genotype 1 infection. We analyzed data from 515 patients with chronic hepatitis C, confirmed by liver biopsy, assessing anthropometric, biochemical, metabolic, virologic, and ultrasonography features. Transient elastography was performed to measure liver stiffness. Steatosis was identified with ultrasonography based on detection of a bright liver echo pattern. Ultrasonography identified steatosis in 5% or more of parenchyma of the liver with 63.6% sensitivity, 90.4% specificity, an 87.5% positive predictive value (PPV), and a 70.3% negative predictive value (NPV). The higher the degree of steatosis (based on histology analysis), the higher the sensitivity values and NPVs (up to values of 75.3% and 93.8%, respectively, for steatosis in ≥30% of liver), and the lower the specificity values and PPVs (down to values of 69.8% and 31.7% for steatosis in ≥30% of liver, respectively). Body mass index of 30 kg/m(2) or greater (odds ratio, 2.761; 95% confidence interval, 1.156-6.595; P = .02) and liver stiffness measurements of 8.9 kPa or higher (odds ratio, 3.128; 95% confidence interval, 1.715-5.706; P ultrasonography when there was 5% or more steatosis, as well as when there was 10% or more, 20% or more, or 30% or more steatosis. Ultrasonography detects steatosis with low levels of accuracy in patients with chronic hepatitis C virus genotype 1 infection; it has low NPVs for amounts of steatosis of 5% or more and low PPVs for livers with moderate-severe amounts. Higher body mass indexes and liver stiffness measurements are associated with false-negative results in steatosis detection by ultrasonography. Copyright © 2014 AGA Institute.

    By reducing energy density, low-energy sweeteners (LES) might be expected to reduce energy intake (EI) and body weight (BW). To assess the totality of the evidence testing the null hypothesis that LES exposure (versus sugars or unsweetened alternatives) has no effect on EI or BW, we conducted a systematic review of relevant studies in animals and humans consuming LES with ad libitum access to food energy. In 62 of 90 animal studies exposure to LES did not affect or decreased BW. Of 28 reporting increased BW, 19 compared LES with glucose exposure using a specific 'learning' paradigm. Twelve prospective cohort studies in humans reported inconsistent associations between LES use and body mass index (-0.002 kg m(-)(2) per year, 95% confidence interval (CI) -0.009 to 0.005). Meta-analysis of short-term randomized controlled trials (129 comparisons) showed reduced total EI for LES versus sugar-sweetened food or beverage consumption before an ad libitum meal (-94 kcal, 95% CI -122 to -66), with no difference versus water (-2 kcal, 95% CI -30 to 26). This was consistent with EI results from sustained intervention randomized controlled trials (10 comparisons). Meta-analysis of sustained intervention randomized controlled trials (4 weeks to 40 months) showed that consumption of LES versus sugar led to relatively reduced BW (nine comparisons; -1.35 kg, 95% CI -2.28 to -0.42), and a similar relative reduction in BW versus water (three comparisons; -1.24 kg, 95% CI -2.22 to -0.26). Most animal studies did not mimic LES consumption by humans, and reverse causation may influence the results of prospective cohort studies. The preponderance of evidence from all human randomized controlled trials indicates that LES do not increase EI or BW, whether compared with caloric or non-caloric (for example, water) control conditions. Overall, the balance of evidence indicates that use of LES in place of sugar, in children and adults, leads to reduced EI and BW, and possibly also

    Some factors that may affect human perception thresholds of the vertical whole-body vibrations were investigated in two laboratory experiments with recumbent subjects. In the first experiment, the effects of gender and age of subjects on perception were investigated with three groups of 12 subjects, i.e., young males, young females and old males. For continuous sinusoidal vibrations at 2, 4, 8, 16, 31.5 and 63 Hz, there were no significant differences in the perception thresholds between male and female subjects, while the thresholds of young subjects tended to be significantly lower than the thresholds of old subjects. In the second experiment, the effect of vibration duration was investigated by using sinusoidal vibrations, at the same frequencies as above, modulated by the Hanning windows with different lengths (i.e., 0.5, 1.0, 2.0 and 4.0 s) for 12 subjects. It was found that the peak acceleration at the threshold tended to decrease with increasing duration of vibration. The perception thresholds were also evaluated by the running root-mean-square (rms) acceleration and the fourth power acceleration method defined in the current standards. The differences in the threshold of the transient vibrations for different durations were less with the fourth power acceleration method. Additionally, the effect of the integration time on the threshold was investigated for the running rms acceleration and the fourth power acceleration. It was found that the integration time that yielded less differences in the threshold of vibrations for different durations depended on the frequency of vibration.

    The dependence of tumor cells, particularly those originating in the brain, on glucose is the target of the ketogenic diet, which creates a plasma nutrient profile similar to fasting: increased levels of ketone bodies and reduced plasma glucose concentrations. The use of ketogenic diets has been of particular interest for therapy in brain tumors, which reportedly lack the ability to oxidize ketone bodies and therefore would be starved during ketosis. Because studies assessing the tumors' ability to oxidize ketone bodies are lacking, we investigated in vivo the extent of ketone body oxidation in 2 rodent glioma models. Ketone body oxidation was studied using (13)C MR spectroscopy in combination with infusion of a (13)C-labeled ketone body (beta-hydroxybutyrate) in RG2 and 9L glioma models. The level of ketone body oxidation was compared with nontumorous cortical brain tissue. The level of (13)C-beta-hydroxybutyrate oxidation in 2 rat glioma models was similar to that of contralateral brain. In addition, when glioma-bearing animals were fed a ketogenic diet, the ketone body monocarboxylate transporter was upregulated, facilitating uptake and oxidation of ketone bodies in the gliomas. These results demonstrate that rat gliomas can oxidize ketone bodies and indicate upregulation of ketone body transport when fed a ketogenic diet. Our findings contradict the hypothesis that brain tumors are metabolically inflexible and show the need for additional research on the use of ketogenic diets as therapy targeting brain tumor metabolism. © The Author(s) 2016.

    Objectives : The aim of this study was to assess whether the time of vitamin D supplementation after birth, season of birth and the type of feeding affected current body weight, body height and BMI among children aged 3-56 months from two cohorts. Additionally, it was analysed whether birth weight and birth length correlated with current BMI, body height and body weight in both cohorts of children. Methods : The study material included 1930 children from the two cohorts, measured in two following periods: 1993-1997 and 2004-2008. Finally 849 healthy individuals aged 3-56 months were included in the analysis. Multiple stepwise regression model was applied to find the group of the most important variables explaining current body weight, body height and BMI. Moreover generalized linear models for two way interactions were used. Results : The season of birth, time of supplementation of vitamin D, but also birth weight and length might affect current body weight. Individuals' height could be associated with birth length and the season of birth. BMI value was probably regulated by birth length and weight. Furthermore, interactions between the time of vitamin D supplementation and season of birth and also between the time of vitamin D supplementation and type of feeding resulting in variation of body weight and BMI in the first years of life were also observed. Conclusions : The study underlines the importance of a supplementation of vitamin D, season of birth and birth weight and length in current weight, height and body proportion in the first 3.5 years of life.

    Full Text Available Purpose: Mindfulness interventions have been shown to treat depressive symptoms and improve quality of life in patients with several chronic diseases, including multiple sclerosis, but to date most evaluation of the effectiveness of mindfulness interventions in multiple sclerosis have used patients receiving standard care as the control group. Hence we decided to evaluate the effectiveness of a group-based body-affective mindfulness intervention by comparing it with a psycho-educational intervention, by means of a randomized controlled clinical trial. The outcome variables (i.e., depression, anxiety, perceived stress, illness perception, fatigue and quality of life were evaluated at the end of the interventions (T1 and after a further 6 months (T2.Methods: Of 90 multiple sclerosis patients with depressive symptoms (Beck Depression Inventory-II score greater than 13 who were randomized, 71 completed the intervention (mindfulness group n = 36; psycho-educational group n = 35. The data were analyzed with GLM repeated-measures ANOVA followed by pairwise comparisons.Results: Per-protocol analysis revealed a time by group interaction on Beck Depression Inventory-II score, with the mindfulness intervention producing a greater reduction in score than the psycho-educational intervention, both at T1 and at T2. Furthermore, the mindfulness intervention improved patients’ quality of life and illness perception at T1 relative to the baseline and these improvements were maintained at the follow-up assessment (T2. Lastly, both interventions were similarly effective in reducing anxiety and perceived stress; these reductions were maintained at T2. A whole-sample intention-to-treat (ITT analysis broadly confirmed the effectiveness of the mindfulness intervention.Conclusion: In conclusion, these results provide methodologically robust evidence that in multiple sclerosis patients with depressive symptoms mindfulness interventions improve symptoms of depression

    Extensive measurements of calf body temperature are limited in the literature. In this study, body temperatures were collected by taping a data logger to the skin over the tail vein opposing the rectum of Holstein calves between 4 and 60d of age during 3 different periods of the summer and fall. The summer period was separated into moderate (21-33°C average low to high) and hot (25-37°C) periods, whereas the fall exhibited cool (11-19°C) ambient temperatures. Tail temperatures were compared in a mixed model ANOVA using ambient temperature, age of calf, and time of day (10-min increments) as fixed effects and calf as a random effect. Measures within calf were modeled as repeated effects of type autoregressive 1. Calf temperature increased 0.0325°C (±0.00035) per 1°C increase in ambient temperature. Body temperature varied in a distinct, diurnal pattern with time of day, with body temperatures being lowest around 0800h and highest between 1700 and 2200h. During periods of hot weather, the highest calf temperature was later in the day (~2200h). Calf minimum, maximum, and average body temperatures were all higher in hot than in moderate periods and higher in moderate than in cool periods. Copyright © 2016 American Dairy Science Association.

    People with multiple sclerosis (MS) frequently complain of chronic or fluctuating fatigue, sometimes accompanied by pain. From a phenomenological point of view, both fatigue and pain are seen as aspects of suffering which adversely affect the physical, psychological, social and even existential dimensions of the individual life. The present study discusses changes in identity and body awareness in people with MS who completed a 5-d trekking to Machu Picchu in Peru in 2012, after having completed a physical training schedule for several months. All nine participants took part in a focus group organized after the trip. The Interpretative Phenomenological Analysis (IPA) was used to gain insight in their experiences and to refine pre-existing theoretical understanding of body awareness and identity. Our phenomenological analysis clarified how aspects of the participants' identity and body experience before, during and after the journey influenced major daily themes as "body", "lived body", "behaviour" and "relationship" and how this contributed to a meaningful experience. When participants describe how they started looking at their own identity more consciously after being watched through the others' eyes, this resulted in a joyful transcending of their bodily power and endurance. In general, our data suggest that the more extreme, positive lived body experiences during the expedition were necessary for optimizing daily "routine" functioning. Participating in Machu Picchu expedition appeared to have a deep and profound effect on body awareness and identity. Participants experienced their body once again as theirs, owning it and above all, allowing it to be a source of strength, joy and meaningfulness. While MS determined their lives prior to the journey, they now could look at MS as a part of what they are, without totally being absorbed in it. So being a patient with MS before, resulted in merely having MS after the climb. Implications for Rehabilitation Patients

    Knowledge of factors influencing the timing of reproduction is important for animal conservation and management. Brown bears (Ursus arctos) are able to vary the birth date of their cubs in response to their fat stores, but little information is available about the timing of implantation and parturition in free-ranging brown bears. Body temperature and activity of pregnant brown bears is higher during the gestation period than during the rest of hibernation and drops at parturition. We compared mean daily body temperature and activity levels of pregnant and nonpregnant females during preimplantation, gestation, and lactation. Additionally we tested whether age, litter size, primiparity, environmental conditions, and the start of hibernation influence the timing of parturition. The mean date of implantation was 1 December (SD = 12), the mean date of parturition was 26 January (SD = 12), and the mean duration of the gestation period was 56 days (SD = 2). The body temperature of pregnant females was higher during the gestation and lactation periods than that of nonpregnant bears. The body temperature of pregnant females decreased during the gestation period. Activity recordings were also used to determine the date of parturition. The parturition dates calculated with activity and body temperature data did not differ significantly and were the same in 50% of the females. Older females started hibernation earlier. The start of hibernation was earlier during years with favorable environmental conditions. Dates of parturition were later during years with good environmental conditions which was unexpected. We suggest that free-ranging pregnant brown bears in areas with high levels of human activities at the beginning of the denning period, as in our study area, might prioritize investing energy in early denning than in early parturition during years with favorable environmental conditions, as a strategy to prevent disturbances caused by human.

    Tamoxifen is a selective estrogen receptor (ER) modulator which is widely used to generate inducible conditional transgenic mouse models. Activation of ER signaling plays an important role in the regulation of adipose tissue (AT) metabolism. We therefore tested the hypothesis that tamoxifen administration causes changes in AT biology in vivo. 12 weeks old male C57BL/6NTac mice were treated with either tamoxifen (n = 18) or vehicle (n = 18) for 5 consecutive days. Tamoxifen treatment effects on body composition, energy homeostasis, parameters of AT biology, glucose and lipid metabolism were investigated up to an age of 18 weeks. We found that tamoxifen treatment causes: I) significantly increased HbA 1c , triglyceride and free fatty acid serum concentrations (p < 0.01), II) browning of subcutaneous AT and increased UCP-1 expression, III) increased AT proliferation marker Ki67 mRNA expression, IV) changes in adipocyte size distribution, and V) transient body composition changes. Tamoxifen may induce changes in body composition, whole body glucose and lipid metabolism and has significant effects on AT biology, which need to be considered when using Tamoxifen as a tool to induce conditional transgenic mouse models. Our data further suggest that tamoxifen-treated wildtype mice should be characterized in parallel to experimental transgenic models to control for tamoxifen administration effects. - Highlights: • Tamoxifen treatment causes significantly increased HbA 1c , triglyceride and free fatty acid serum concentrations. • Tamoxifen induces browning of subcutaneous AT and increased UCP-1 expression. • Tamoxifen changes adipocyte size distribution, and transient body composition

    Genetic rearrangements are a hallmark of several forms of leukemia and can lead to oncogenic fusion proteins. One example of an affected chromosomal region is the gene coding for Nup214, a nucleoporin that localizes to the cytoplasmic side of the nuclear pore complex (NPC). We investigated two such fusion proteins, SET-Nup214 and SQSTM1 (sequestosome)-Nup214, both containing C-terminal portions of Nup214. SET-Nup214 nuclear bodies containing the nuclear export receptor CRM1 were observed in the leukemia cell lines LOUCY and MEGAL. Overexpression of SET-Nup214 in HeLa cells leads to the formation of similar nuclear bodies that recruit CRM1, export cargo proteins, and certain nucleoporins and concomitantly affect nuclear protein and poly(A) + RNA export. SQSTM1-Nup214, although mostly cytoplasmic, also forms nuclear bodies and inhibits nuclear protein but not poly(A) + RNA export. The interaction of the fusion proteins with CRM1 is RanGTP-dependent, as shown in co-immunoprecipitation experiments and binding assays. Further analysis revealed that the Nup214 parts mediate the inhibition of nuclear export, whereas the SET or SQSTM1 part determines the localization of the fusion protein and therefore the extent of the effect. SET-Nup214 nuclear bodies are highly mobile structures, which are in equilibrium with the nucleoplasm in interphase and disassemble during mitosis or upon treatment of cells with the CRM1-inhibitor leptomycin B. Strikingly, we found that nucleoporins can be released from nuclear bodies and reintegrated into existing NPC. Our results point to nuclear bodies as a means of preventing the formation of potentially insoluble and harmful protein aggregates that also may serve as storage compartments for nuclear transport factors. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    As public discourse surrounding obesity highlights the societal costs of obesity and individual's own responsibility for their weight, being overweight is often framed as immoral. Such 'moralizing' messages about being overweight may be a psychological threat for those with high body mass. Attempting to counter-moralise the public discourse (i.e. actively arguing that there is nothing 'immoral' about being overweight) may relieve this threat, inducing people, especially those with higher (perceived) weight, to engage in healthier behaviours. Two experiments were performed among Dutch and US participants. (Counter-)moralisation was manipulated. Body mass and weight-related self-perceptions were measured. The dependent variable was healthy vs. unhealthy snack choice. (Counter-)moralisation and (perceived) overweight jointly predicted snack choice: counter-moralising messages induced healthy snacking, but only among those who regarded themselves to have a high body mass. The effects of moralising vs. counter-moralising obesity depended on one's (perceived) overweight. This suggests that, for people with relatively high weight, the current moralising public discourse on obesity works in counterproductive ways. Campaigns that 'counter-moralize' obesity (i.e. that refute moralising messages) are more productive, although they should be tailored to those who see themselves as being overweight.

    Penguins naturally fast each year during breeding and again whilst moulting, and may lose more than 40% of body mass during a fast. Fasting in emperor (Aptenodytes forsteri) and king (Aptenodytes patagonicus) penguins has been divided into three phases, with phase III characterised by an increased rate of body mass loss, increased plasma corticosterone concentrations, and a change in behaviour leading to abandonment of the breeding attempt and return to sea to feed. Initial corticosterone concentrations and corticosterone responses to a handling stressor were measured in the current study to determine if they increase during phase III of fasting in Adelie penguins (Pygoscelis adeliae). The study was conducted in 2001 at the northern Cape Bird colony on Ross Island, Antarctica. Penguin breeding on Ross Island was disrupted in the 2001-2002 summer by a large iceberg (B15A) which stopped the normal movement of sea ice in the Ross Sea. Penguins departing from the Cape Bird colony were lighter than returning or incubating birds (3.39+/-0.10cf. 4.16+/-0.06 and 4.07+/-0.08kg). It is likely that the departing birds were males that had been lighter than normal when they arrived at the colony. Initial plasma corticosterone concentrations were higher in departing than returning or incubating penguins (6.89+/-1.69cf. 2.36+/-0.42 and 1.08+/-0.19ng/ml). Corticosterone responses to handling were also greater in departing penguins. Initial plasma corticosterone, concentrations at 30min and total and corrected integrated corticosterone responses were inversely related to body mass in departing penguins, whereas there were no relationships in arriving penguins. beta-hydroxybutyrate and uric acid concentrations were consistent with departing birds having entered phase III of fasting. The results indicate that corticosterone and corticosterone responses are elevated in phase III of fasting in the Adelie penguin.

    Cosmetic surgery is no longer just for females. More men are opting for cosmetic procedures, with marked increases seen in both minimally invasive and surgical options over the last decade. Compared to females, relatively little work has specifically focused on factors predicting males' attitudes toward cosmetic surgery. Therefore, we evaluated a number of variables that may predict some facet of men's attitudes toward cosmetic surgery according to evidence reported in the literature METHODS: A total of 151 male patients who applied for a surgical or minimally invasive cosmetic surgery procedure (patient group) and 151 healthy male volunteers who do not desire any type of cosmetic procedure (control group) were asked to fill out questionnaires about measures of body image, media exposure (television and magazine), social network site use, masculine gender role stress and religious attitudes. Our findings showed that lower ratings of body image satisfaction, increased time spent watching television, more frequent social network site use and higher degrees of masculine gender role stress were all significant predictors of attitudes toward cosmetic surgery among males. The current study confirmed the importance of body image dissatisfaction as a predictor of the choice to undergo cosmetic procedure. More importantly, a new predictor of cosmetic procedure attitudes was identified, namely masculine gender role stress. Finally, we demonstrated the effects television exposure and social network site use in promoting acceptance of surgical and nonsurgical routes to appearance enhancement.

    Evidence of probiotics effects on gut function, brain activity and emotional behaviour were provided. Probiotics can have dramatic effects on behaviour through the microbiome-gut-brain axis, through vagus nerve. We investigated whether chronic probiotic intake could modulate psychological state, eating behaviour and body composition of normal weight obese (NWO) and preobese-obese (PreOB/OB) compared to normal weight lean women (NWL). 60 women were enrolled. At baseline and after a 3-week probiotic oral suspension (POS) intake, all subjects underwent evaluation of body composition by anthropometry and dual X-ray absorptiometry, and psychological profile assessment by self-report questionnaires (i.e. EDI-2, SCL90R and BUT). Statistical analysis was carried out using paired t test or a non-parametric Wilcoxon test to evaluate differences between baseline and after POS intake, one-way ANOVA to compare all three groups and, where applicable, Chi square or t test were used to assess symptoms. Of the 48 women that concluded the study, 24% were NWO, 26% were NWL and 50% were PreOB/OB. Significant differences in body composition were highlighted among groups both at baseline and after a POS (p women. At baseline and after POS intake, all subjects tested were negative to SCL90R_GSI scale, but after treatment subjects positive to BUT_GSI scale were significantly reduced (8.33%) (p women. Further research is needed on a larger population and for a longer period of treatment before definitive conclusions can be made. Trial registration ClinicalTrials.gov Id: NCT01890070.

The procedure involves injection of bone cement into a fractured vertebra. In this study, we investigated whether the distribution of the cement in the vertebral body is related to the occurrence of recompression after surgery. Patients and methods: A total of 172 patients diagnosed with OVCF, from January 2008 to June 2013, were retrospectively reviewed. Fifty of these patients experienced recompression after surgery during the follow-up period (recompression group, and 122 patients had no recompression observed during the follow-up period (control group. Statistical analysis was performed to compare clinical and operative parameters between these two groups. Results: Differences were found in bone cement distribution between the recompression group and control group (P=0.001. Patients with bone cement distributed around both upper and lower endplates had a significantly less incidence of recompression (4/50 patients, when compared to other patterns of cement distribution (eg, below upper endplate, above lower endplate, and in the middle of vertebral body. The logistic multiple regression analysis also indicated that patients with bone cement distributed around both the upper and lower endplates had a lower risk of recompression when compared to patients with bone cement distributed in the middle of vertebral body (odds ratio =0.223, P=0.003. Conclusion: We herein suggest that the control of bone cement distribution during surgery provides beneficial effects on reducing the risks of recompression after PVP treatment in patients with OVCF.

    Secondary sex ratios of animals with genetically determined sex may considerably deviate from equality. These deviations may be attributed to several proximate and ultimate factors. Sex ratio theory explains some of them as strategic decisions of mothers improving their fitness by selective investment in sons or daughters, e.g. local resource competition hypothesis (LRC) suggests that philopatric females tend to produce litters with male-biased sex ratios to avoid future competition with their daughters. Until now, only little attention has been paid to examine predictions of sex ratio theory in snakes possessing genetic sex determination and exhibiting large variance in allocation of maternal investment. Cuban boa is an endemic viviparous snake producing large-bodied newborns (˜200 g). Extremely high maternal investment in each offspring increases importance of sex allocation. In a captive colony, we collected breeding records of 42 mothers, 62 litters and 306 newborns and examined secondary sex ratios (SR) and sexual size dimorphism (SSD) of newborns. None of the examined morphometric traits of neonates appeared sexually dimorphic. The sex ratio was slightly male biased (174 males versus 132 females) and litter sex ratio significantly decreased with female snout-vent length. We interpret this relationship as an additional support for LRC as competition between mothers and daughters increases with similarity of body sizes between competing snakes.

    Depression is linked with alexithymia, anxiety, high HbA1c concentrations, disturbances of cortisol secretion, increased prevalence of diabetes complications and all-cause mortality. The psycho-educational method 'affect school with script analysis' and the mind-body therapy 'basic body awareness treatment' will be trialled in patients with diabetes, high HbA1c concentrations and psychological symptoms. The primary outcome measure is change in symptoms of depression. Secondary outcome measures are changes in HbA1c concentrations, midnight salivary cortisol concentration, symptoms of alexithymia, anxiety, self-image measures, use of antidepressants, incidence of diabetes complications and mortality. Two studies will be performed. Study I is an open-labeled parallel-group study with a two-arm randomized controlled trial design. Patients are randomized to either affect school with script analysis or to basic body awareness treatment. According to power calculations, 64 persons are required in each intervention arm at the last follow-up session. Patients with type 1 or type 2 diabetes were recruited from one hospital diabetes outpatient clinic in 2009. The trial will be completed in 2016. Study II is a multicentre open-labeled parallel-group three-arm randomized controlled trial. Patients will be randomized to affect school with script analysis, to basic body awareness treatment, or to treatment as usual. Power calculations show that 70 persons are required in each arm at the last follow-up session. Patients with type 2 diabetes will be recruited from primary care. This study will start in 2016 and finish in 2023. For both studies, the inclusion criteria are: HbA1c concentration ≥62.5 mmol/mol; depression, alexithymia, anxiety or a negative self-image; age 18-59 years; and diabetes duration ≥1 year. The exclusion criteria are pregnancy, severe comorbidities, cognitive deficiencies or inadequate Swedish. Depression, anxiety, alexithymia and self-image are assessed

    Growth patterns in early life are associated with later health. The effect of nutrition during in utero development on later body composition is unclear. We evaluated whether prenatal early invitation to food and/or multiple micronutrient supplementation (MMS) in pregnancy has an effect on offspring body composition at 54 months of age. In Maternal and Infant Nutrition Interventions in Matlab trial (ISRCTN16581394) in Bangladesh, 4436 pregnant women were randomised into six equally sized groups: double-masked supplementation with capsules of either 30 mg Fe and 400 μg folic acid, or 60 mg Fe and 400 μg folic acid, or MMS (15 micronutrients), was combined with a randomised early invitation (around 9 weeks) or a usual invitation (around 20 weeks) to start food supplementation (608 kcal 6 days per week). At 54 months, the body composition of the offspring was assessed by leg-to-leg bioelectrical impedance analysis. Of the 3267 live singletons with birth anthropometry, 2290 children were measured at 54 months, representing 70% of the live births. There was no interaction between the food and micronutrient supplementation on body composition outcomes. There were no significant differences in a range of anthropometric and body composition measurements, including weight, height, mid-upper arm circumference, head circumference, skinfold thickness, and fat mass and fat-free mass between the different prenatal food and micronutrient groups using an intention-to-treat analysis. This analysis shows that early invitation to food supplementation and MMS provided to rural Bangladeshi women during pregnancy did not affect offspring body composition at 54 months of age. © 2012 Blackwell Publishing Ltd.

    Agavins act as a fermentable dietary fiber and have attracted attention due to their potential for reducing the risk of disease. Therefore, we evaluated the effect of supplementation using 10% agavins with a short-degree of polymerization (SDP) from Agave angustifolia Haw. (AASDP) or Agave potatorum Zucc. (APSDP) along with chicory fructans (RSE) as a reference for 5 weeks, on the energy intake, body weight gain, satiety-related hormones from the gut and blood (GLP-1 and ghrelin), blood glucose and lipids, and short-chain fatty acids (SCFAs) from the gut of ad libitum-fed mice. We evaluated the energy intake daily and weight gain every week. At the end of the experiment, portal vein blood samples as well as intestinal segments and the stomach were collected to measure glucagon-like peptide-1 (GLP-1) and ghrelin using RIA and ELISA kits, respectively. Colon SCFAs were measured using gas chromatography. The energy intake, body weight gain, and triglycerides were lower in the fructan-fed mice than in the STD-fed mice. The AASDP, APSDP, and RSE diets increased the serum levels of GLP-1 (40, 93, and 16%, respectively vs. STD) (P ≤ 0.05), whereas ghrelin was decreased (16, 38, and 42%, respectively) (P ≤ 0.05). Butyric acid increased significantly in the APSDP-fed mice (26.59 mmol g(-1), P ≤ 0.001) compared with that in the AASDP- and RSE-fed mice. We concluded that AASDP and APSDP are able to promote the secretion of the peptides involved in appetite regulation, which might help to control obesity and its associated metabolic disorder.

    The consumption of orange juice may lead to reduced oxidative stress and may enhance the antioxidant defense system. The aim was to evaluate the effects of the intake of orange juice containing either normal (NPJ) or high (HPJ) concentrations of polyphenols (299 and 745 mg/d, respectively) on the antioxidant defense system, oxidative stress biomarkers, and clinical signs of metabolic syndrome in 100 nonsmoking subjects who were either overweight or obese. A randomized, double-blind crossover study was conducted over two 12-wk periods with a 7-wk washout period. The effects on enzymatic and nonenzymatic blood antioxidant defense systems, urinary and plasma oxidative stress biomarkers, and clinical signs of metabolic syndrome were evaluated before and after an intervention with both of the orange juices. Paired t tests and linear mixed-effects models were used to evaluate the effects of juice, time, and interactions. The intake of either NPJ or HPJ led to a decrease in urinary 8-hydroxy-2'-deoxyguanosine (NPJ: 935 ± 134 to 298 ± 19 ng/mg creatinine; HPJ: 749 ± 84 to 285 ± 17 ng/mg creatinine), 8-iso-prostaglandin F2α (NPJ: 437 ± 68 to 156 ± 14 ng/mg creatinine; HPJ: 347 ± 43 to 154 ± 13 ng/mg creatinine), erythrocyte catalase, and glutathione reductase activities. A decrease was also observed in body mass index, waist circumference, and leptin (all P < 0.05). The NPJ intervention decreased systolic and diastolic blood pressures (systolic blood pressure: 128 ± 1 to 124 ± 2 mm Hg; diastolic blood pressure: 79 ± 1 to 76 ± 1 mm Hg), whereas the HPJ intervention increased erythrocyte superoxide dismutase (SOD) activity (17.7 ± 1.5 to 23.1 ± 1.7 U/mg hemoglobin). Our results show that the consumption of either NPJ or HPJ protected against DNA damage and lipid peroxidation, modified several antioxidant enzymes, and reduced body weight in overweight or obese nonsmoking adults. Only blood pressure and SOD activity were influenced differently by the different

    Although bi-directional relationships between high body mass index (BMI) and affective symptoms have been found, no study has investigated the relationships across the life course. There has also been little exploration of whether the fat mass and obesity-associated (FTO) rs9939609 single-nucleotide polymorphism (SNP) is associated with affective symptoms and/or modifies the relationship between BMI and affective symptoms. In the MRC National Survey of Health and Development (NSHD), 4556 participants had at least one measure of BMI and affective symptoms between ages 11 and 60-64 years. A structural equation modelling framework was used with the BMI trajectory fitted as latent variables representing BMI at 11, and adolescent (11-20 years), early adulthood (20-36 years) and midlife (36-53 years) change in BMI. Higher levels of adolescent emotional problems were associated with greater increases in adult BMI and greater increases in early adulthood BMI were associated with higher subsequent levels of affective symptoms in women. The rs9939609 risk variant (A allele) from 2469 participants with DNA genotyping at age 53 years showed mostly protective effect modification of these relationship. Increases in adolescent and early adulthood BMI were generally not associated with, or were associated with lower levels, of affective symptoms in the FTO risk homozygote (AA) group, but positive associations were seen in the TT group. These results suggest bi-directional relationships between higher BMI and affective symptoms across the life course in women, and that the relationship could be ameliorated by rs9939609 risk variant.

    Metabolic syndrome (MetS) leads to changes in enzymatic activities, oxidative and inflammatory parameters. Adenosine deaminase (ADA), dipeptidyl peptidase IV (DPP-IV), butyrylcholinesterase (BuChE) and γ-glutamyltransferase (γ-GT) activities, C-reactive protein (hsCRP) and nitric oxide levels (NOx), as well as oxidative stress markers were analyzed in 39 subjects with MetS and 48 controls. Also, the influence of body mass index (BMI) and anthropometric measurements were evaluated. Disturbances in antioxidant defenses and higher γ-GT and BuChE activities, NOx and hsCRP levels were observed in subjects with MetS. These findings remained associated with MetS after adjustment for BMI, except for hsCRP. ADA was correlated with age, insulin levels and HOMA-IR index in MetS. DPP-IV and total cholesterol (TC), BuChE activity and TC, and VIT C and hsCRP levels also were correlated. The analyzed parameters may reflect the inflammatory state of the MetS, and could contribute to prevention and control of various aspects of this syndrome.

    The primary purpose of this study was to examine, using meta-analytical measures, whether research into the performance of whole-body, psychomotor tasks following moderate and heavy exercise demonstrates an inverted-U effect. A secondary purpose was to compare the effects of acute exercise on tasks requiring static maintenance of posture versus dynamic, ballistic skills. Moderate intensity exercise was determined as being between 40% and 79% maximum power output (ẆMAX) or equivalent, while ≥80% ẆMAX was considered to be heavy. There was a significant difference (Zdiff=4.29, p=0.001, R(2)=0.42) between the mean effect size for moderate intensity exercise (g=0.15) and that for heavy exercise size (g=-0.86). These data suggest a catastrophe effect during heavy exercise. Mean effect size for static tasks (g=-1.24) was significantly different (Zdiff=3.24, p=0.001, R(2)=0.90) to those for dynamic/ballistic tasks (g=-0.30). The result for the static versus dynamic tasks moderating variables point to perception being more of an issue than peripheral fatigue for maintenance of static posture. The difference between this result and those found in meta-analyses examining the effects of acute exercise on cognition shows that, when perception and action are combined, the complexity of the interaction induces different effects to when cognition is detached from motor performance.

    Body weight (BW) cycling, the yo-yo effect, is generally thought to have adverse effects on human metabolic health. However, human and animal experiments are limited in number and do not provide clear answers, partly due to large variations in experimental design, parameters measured, and definitions of BW cycling. Here, we examined the effect of repetitive BW cycling versus single- and non-cycling control groups, without alterations in diet composition, on steady state BW and metabolic parameters. We induced well-defined BW cycles on a semi-purified high fat diet in C57BL/6J mice, a well-described animal model for diet-induced obesity, and measured energy expenditure and relevant metabolic parameters. Our setup indeed resulted in the intended BW changes and always reached a stage of energy balance. A history of weight cycling did not result in increased BW or fat mass compared with the control group, nor in deteriorated serum concentrations of glucose, adipokines and serum triglyceride and free fatty acid (FFA) concentrations. If anything, BW tended to be reduced, presumably because of a reduced overall energy intake in BW cycling animals. Repeated cycling in BW without changes in diet composition does not lead to impaired metabolic health nor increased BW (gain).

    This study compared productivity of dairy cows with different body weight (BW), but a constant ratio of maintenance to production requirements in their first lactation, in a pasture-based production system with spring calving. Two herds, Herd L (13 and 14 large cows in 2003 and 2004 respectively; average BW after calving, 721 kg) and Herd S (16 small cows in both years; 606 kg) [Correction added after online publication 14 January 2011: 16 small cows in both years; 621 kg was changed to 16 small cows in both years; 606 kg], all in their second or following lactations, were each allocated 6 ha of pasture and rotationally grazed on 10 parallel paddocks with equal herbage offer and nutritional values. Winter hay, harvested from the same pastures, was offered ad libitum in the indoor periods in a tied stall barn. Each herd received, per lactation and year, approximately 2000 kg dry matter (DM) of concentrates and of fodder beets, equally distributed to every individual. Indoors, the L-cows ingested more DM than the S-cows (18.7 vs. 16.3 kg DM/cow per day; p pasture (17.9 vs. 15.5 kg DM/cow per day; p pasture-based forage. © 2010 Blackwell Verlag GmbH.

    This paper reviews available studies on the relationship between acculturation and obesity among children of immigrants who have at least one foreign-born parent. A systematic review of relevant studies was undertaken using PubMed, Web of Science, and PsychInfo. The initial search identified 1317 potentially relevant publications, of which 21 were retained after three rounds of screening. Most studies were conducted in the U.S. The majority of studies used BMI or overweight/obesity prevalence as the outcome variable, while two studies used dietary intake. Three studies used standardized acculturation scales, while most of the studies used generation, duration of residency in host country, and language as proxy measures of acculturation. The relationship between acculturation and outcomes varied between the host countries and origin countries for children of immigrants. This study suggests children of immigrants with different cultural backgrounds may interact with host countries to varying degrees, ultimately influencing their diet behaviours and body weight status. Researchers are encouraged to adopt standardized acculturation scales to compare the results across countries and populations.

    Fat mobilization to meet energy requirements during early lactation is inevitable because of insufficient feed intake, but differs greatly among high-yielding dairy cows. Therefore, we studied milk production, feed intake, and body condition as well as metabolic and endocrine changes in high-yielding dairy cows to identify variable strategies in metabolic and endocrine adaptation to overcome postpartum metabolic load attributable to milk production. Cows used in this study varied in fat mobilization around calving, as classified by mean total liver fat concentrations (LFC) postpartum. German Holstein cows (n=27) were studied from dry off until d 63 postpartum in their third lactation. All cows were fed the same total mixed rations ad libitum during the dry period and lactation. Plasma concentrations of metabolites and hormones were measured in blood samples taken at d 56, 28, 15, and 5 before expected calving and at d 1 and once weekly up to d 63 postpartum. Liver biopsies were taken on d 56 and 15 before calving, and on d 1, 14, 28, and 49 postpartum to measure LFC and glycogen concentrations. Cows were grouped accordingly to mean total LFC on d 1, 14, and 28 in high, medium, and low fat-mobilizing cows. Mean LFC (±SEM) differed among groups and were 351±14, 250±10, and 159±9 mg/g of dry matter for high, medium, and low fat-mobilizing cows, respectively, whereas hepatic glycogen concentrations postpartum were the highest in low fat-mobilizing cows. Cows in the low group showed the highest dry matter intake and the least negative energy balance postpartum, but energy-corrected milk yield was similar among groups. The decrease in body weight postpartum was greatest in high fat-mobilizing cows, but the decrease in backfat thickness was greatest in medium fat-mobilizing cows. Plasma concentrations of nonesterified fatty acids and β-hydroxybutyrate were highest around calving in high fat-mobilizing cows. Plasma triglycerides were highest in the medium group and

    Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × 2 factorial arrangement: 2 prepartum BCS categories (4.0 and 5.0, based on a 10-point scale; BCS4, BCS5) obtained via differential feeding management during late-lactation, and 2 levels of energy intake during the 3 wk preceding calving (75 and 125% of estimated requirements). Subcutaneous adipose tissue was harvested via biopsy at -1, 1, and 4 wk relative to parturition. Quantitative polymerase chain reaction was used to measure mRNA and microRNA (miRNA) expression of targets related to fatty acid metabolism (lipogenesis, lipolysis), adipokine synthesis, and inflammation. Both prepartum BCS and feeding management had a significant effect on mRNA and miRNA expression throughout the peripartum period. Overfed BCS5 cows had the greatest prepartum expression of fatty acid synthase (FASN) and an overall greater expression of leptin (LEP); BCS5 was also associated with greater overall adiponectin (ADIPOQ) and peroxisome proliferator-activated receptor gamma (PPARG), whereas overfeeding upregulated expression of proadipogenic miRNA. Higher postpartum expression of chemokine ligand 5 (CCL5) and the cytokines interleukin 6 (IL6) and tumor necrosis factor (TNF) was detected in overfed BCS5 cows. Feed-restricted BCS4 cows had the highest overall interleukin 1 (IL1B) expression. Prepartum feed restriction

    BST-2/tetherin blocks the release of various enveloped viruses including HIV-1 with a "physical tethering" model. The detailed contribution of N-linked glycosylation to this model is controversial. Here, we confirmed that mutation of glycosylation sites exerted an effect of post-translational mis-trafficking, leading to an accumulation of BST-2 at intracellular CD63-positive vesicles. BST-2 with this phenotype potently inhibited the release of multivesicular body-targeted HIV-1 and hepatitis B virus, without affecting the co-localization of BST-2 with EEA1 and LAMP1. These results suggest that N-linked glycosylation of human BST-2 is dispensable for intracellular virion retention and imply that this recently discovered intracellular tethering function may be evolutionarily distinguished from the canonical antiviral function of BST-2 by tethering nascent virions at the cell surface.

    To assess internal radiocontamination of patients with end-stage renal disease (ESRD) who were regularly taking haemodialysis (HD) and living in areas affected by the crippled Fukushima Daiichi nuclear plant after the Great East Japan earthquake on 11 March 2011. Internal radiocontamination in 111 patients with ESRD regularly taking HD at Jyoban Hospital in Iwaki city, Fukushima from July 2012 to November 2012 was assessed with a whole body counter (WBC). The maximum annual effective dose was calculated from the detected Cs-137 levels. Interviews concerning patient dietary preferences and outdoor activities were also conducted. Among the 111 patients tested, internal radiocontamination with Cs-137 was detected in two participants, but the levels were marginal and just exceeded the detection limit (250 Bq/body). The tentatively calculated maximum annual effective dose ranged from 0.008 to 0.009 mSv/year, which is far below the 1 mSv/year limit set by the government of Japan. Relative to 238 non-ESRD participants, patients with ERSD had significantly more opportunities to consume locally grown produce that was not distributed to the market (pnuclear plant. Although HD is suggested to promote Cs-137 excretion, continuous inspection of locally grown produce together with WBC screening for radiocontamination should be continued for patients with ESRD regularly taking HD.

Most existing studies use a wage equation to document dispersion in wages between normal- and overweight, however little is known about the reason for dispersion...... is used to examine the occupation and industry distribution. Most importantly, we find that wage differences between normal-weight and overweight or obese workers are explained by differential firm behavior, both with respect to the job offer arrival rate and to the probability of being promoted.

    Wnt signaling is an important regulator of bone homeostasis. The Wnt co-receptor, namely, low-density lipoprotein receptor-related protein 5 (LRP5), initiates Wnt signal transduction. Recently, we and several other groups have shown that there is a single nucleotide polymorphism (SNP) located in the exon 18 of the LRP5 gene that leads to an amino acid change (3989C > T, A1330V), and is associated with lumbar spine, femoral neck, and radial bone mineral density (BMD), and incidence of fracture. These data suggest that the A1330V variation in the LRP5 gene may affect the pathogenesis of osteoporosis. However, the functional basis of the A1330V variation remains unclear. In the present study, we analyzed the effect of the A1330V variation on Wnt activity. We also investigated the association between this LRP5 SNP and total body BMD using 739 postmenopausal women. LRP5 with the A1330V SNP were transiently coexpressed with Wnt3a in 293T cells and their activity was evaluated by the TCF-Lef reporter assay. In vitro, the TCF-Lef activity in presence of Wnt3a in cells expressing LRP5 and carrying the T allele (Valine at 1330 (V1330)) of exon 18 was significantly reduced as compared to the wild-type allele. The association between the A1330V SNP and total body BMD were replicated in 739 postmenopausal Japanese women (AA vs. VV; P = 0.0026). These data suggest that the V1330 variant in the LRP5 gene decreases Wnt activity, which in turn decreases the BMD.

    Psoriatic arthritis (PsA) is commonly comorbid with psoriasis; the extent of skin lesions is a major contributor to psoriatic disease severity/burden. We evaluated whether extent of skin involvement with psoriasis [body surface area (BSA) > 3% vs ≤ 3%] affects overall clinical and patient-reported outcomes (PRO) in patients with PsA. Using the Corrona PsA/Spondyloarthritis Registry, patient characteristics, disease activity, and PRO at registry enrollment were assessed for patients with PsA aged ≥ 18 years with BSA > 3% versus ≤ 3%. Regression models were used to evaluate associations of BSA level with outcome [modified minimal disease activity (MDA), Health Assessment Questionnaire (HAQ) score, patient-reported pain and fatigue, and the Work Productivity and Activity Impairment questionnaire score]. Adjustments were made for age, sex, race, body mass index, disease duration, and history of biologics, disease-modifying antirheumatic drug, and prednisone use. This analysis included 1240 patients with PsA with known BSA level (n = 451, BSA > 3%; n = 789, BSA ≤ 3%). After adjusting for potential confounding variables, patients with BSA > 3% versus ≤ 3% had greater patient-reported pain and fatigue and higher HAQ scores (p = 2.33 × 10 -8 , p = 0.002, and p = 1.21 × 10 -7 , respectively), were 1.7× more likely not to be in modified MDA (95% CI 1.21-2.41, p = 0.002), and were 2.1× more likely to have overall work impairment (1.37-3.21, p = 0.0001). These Corrona Registry data show that substantial skin involvement (BSA > 3%) is associated with greater PsA disease burden, underscoring the importance of assessing and effectively managing psoriasis in patients with PsA because this may be a contributing factor in PsA severity.

    Full Text Available Body dysmorphic disorder is a type of mental illness, wherein the affected person is concerned with body image, manifested as excessive concern about and preoccupation with a perceived defect of their physical features. Although it is a common disease and has been defined in the literature over a century, it is not a well known disease. Chronic, treatment resistant and sometimes delusional nature could result in severe functional impairment. The diagnosis and appropriate therapy of disorder are crucial because of increased suicidality and reduction in life quality. In this article the symptoms, etiology, clinical features and treatment of body dysmorphic disorder are briefly reviewed.

    This study explores the body disposal patterns in a sample of 54 Korean homicides that occurred between 2006 and 2012. Based on information collected by the police during their investigation, factors that could influence body disposal patterns were examined, such as homicide classification, intention, whether an accomplice was present, and offender mental disorder. Bivariate analyses showed that the majority of the victims who were disposed of were acquaintances of the offenders. Moreover, several offenders were more likely to dispose of the dead body "within hours" of killing the victim. Dead bodies were usually recovered in agricultural areas, forest/wooded areas, as well as residential areas. It was also noteworthy that, in 47 cases, the offender had knowledge of the geographic area where the body was dumped. In cases of "expressive" homicide, victims were more likely to be disposed of somewhere far away (e.g., over 40 km) from the crime scene, whereas "instrumental" homicide victims appeared to be disposed of somewhere closer (e.g., within 30 km) to the crime scene. Results are discussed in light of their practical implications for homicide investigations.

    The high-tech art of digital signal processing (DSP) was pioneered at NASA's Jet Propulsion Laboratory (JPL) in the mid-1960s for use in the Apollo Lunar Landing Program. Designed to computer enhance pictures of the Moon, this technology became the basis for the Landsat Earth resources satellites and subsequently has been incorporated into a broad range of Earthbound medical and diagnostic tools. DSP is employed in advanced body imaging techniques including Computer-Aided Tomography, also known as CT and CATScan, and Magnetic Resonance Imaging (MRI). CT images are collected by irradiating a thin slice of the body with a fan-shaped x-ray beam from a number of directions around the body's perimeter. A tomographic (slice-like) picture is reconstructed from these multiple views by a computer. MRI employs a magnetic field and radio waves, rather than x-rays, to create images.

    2009-06-01

    Males have been facing increasing pressure from the media to attain a lean, muscular physique, and are at risk for body dissatisfaction, disturbed eating and exercise behaviors, and abuse of appearance- and performance-enhancing drugs (APEDs). The aim of the current study was to examine the relationship between body checking and mood, symptoms of muscle dysmorphia, importance of shape and weight, and APED use in undergraduate males. Body checking in males was correlated with weight and shape concern, symptoms of muscle dysmorphia, depression, negative affect, and APED use. Body checking predicted APED use and uniquely accounted for the largest amount of variance in Muscle Dysmorphic Disorder Inventory (MDDI) scores (16%). Findings support the view that body checking is an important construct in male body image, muscle dysmorphia, and body change strategies and suggest a need for further research.

  2. The Body as a Pulse

    Full Text Available The body is the focus of many studies and interventions. Some paradigms conceptualize the body only in relation to its motor-sensory characteristics, while others prioritize its psychological dimensions. With the aim of contributing towards formulating other perspectives within this field, some aspects of Stanley Keleman and Regina Favre's conceptualization of the body are presented here. Starting from clinical situations during seminar groups, we can take the body to be a multifaceted multimedia pulse that is continually [de]constructed through encounters. Together with the author's clinical experiences as an occupational therapist and teacher or undergraduates, these conceptualizations serve as a guide to clinical practice that is thought out, constructed and balanced by the body, using body approaches to promote encounters molded by affections and events, in an attempt to create bodies capable of sustaining the lived intensity of experiences, and which enable self-observation, closeness to other people and production of singularities.

    Full Text Available Abstract Health Issue Body weight is of physical and psychological importance to Canadian women; it is associated with health status, physical activity, body image, and self-esteem. Although the problems associated with overweight and obesity are indeed serious, there are also problems connected to being underweight. Weight prejudice and the dieting industry intensify body image concerns for Canadian women and can have a major negative impact on self-esteem. Key Findings Women have lower BMIs than men, a lower incidence of being overweight and a higher incidence of being underweight. However, women across all weight categories are more dissatisfied with their bodies. Sixty percent of women are inactive, and women with a BMI of 27 or higher are more likely to be inactive than women with lower BMIs. The data show that women are aware of the health benefits of exercise, but there is a gap between knowledge and practice. When asked about barriers to health improvement, 39.7% of women cited lack of time and 39.2% lack of willpower. Data Gaps and Recommendations Weight prejudice must be made unacceptable and positive body image should be encouraged and diversity valued. Health policies should encourage healthy eating and healthy activity. Health curricula for young students should include information about healthy eating, active lifestyle, and self-esteem. Physical activities that mothers can participate in with their families should be encouraged. Research should be funded to elucidate the most effective methods of getting women to become and remain physically active without focusing on appearance.

    Studies assessing the effects of protein supplementation on changes in body composition (BC) and health rarely consider the impact of total protein intake (TPro) or the change in TPro (CTPro) from participants' usual diets. This secondary data analysis assessed the impact of TPro and CTPro on changes in BC and metabolic syndrome (MetS) indexes in overweight and obese middle-aged adults who participated in an exercise training program. Men and women [n = 117; age: 50 ± 0.7 y, body mass index (BMI; in kg/m(2)): 30.1 ± 0.3; means ± SEs] performed resistance exercise 2 d/wk and aerobic exercise 1 d/wk and consumed an unrestricted diet along with 200-kcal supplements (0, 10, 20, or 30 g whey protein) twice daily for 36 wk. Protein intake was assessed via 4-d food records. Multiple linear regression model and stratified analysis were applied for data analyses. Among all subjects, TPro and CTPro were inversely associated (P changes in body mass, fat mass (FM), and BMI. Changes in BC were different (P changes in FM, %FM, and %LM. The gain in LM was not different among groups. In addition, MetS indexes were not influenced by TPro and CTPro. In conjunction with exercise training, higher TPro promoted positive changes in BC but not in MetS indexes in overweight and obese middle-aged adults. Changes in TPro from before to during the intervention also influenced BC responses and should be considered in future research when different TPro is achieved via diet or supplements.

    2015-01-01

    During communication, we perceive and express emotional information through many different channels, including facial expressions, prosody, body motion, and posture. Although historically the human body has been perceived primarily as a tool for actions, there is now increased understanding that the body is also an important medium for emotional expression. Indeed, research on emotional body language is rapidly emerging as a new field in cognitive and affective neuroscience. This article reviews how whole-body signals are processed and understood, at the behavioral and neural levels, with specific reference to their role in emotional communication. The first part of this review outlines brain regions and spectrotemporal dynamics underlying perception of isolated neutral and affective bodies, the second part details the contextual effects on body emotion recognition, and final part discusses body processing on a subconscious level. More specifically, research has shown that body expressions as compared with neutral bodies draw upon a larger network of regions responsible for action observation and preparation, emotion processing, body processing, and integrative processes. Results from neurotypical populations and masking paradigms suggest that subconscious processing of affective bodies relies on a specific subset of these regions. Moreover, recent evidence has shown that emotional information from the face, voice, and body all interact, with body motion and posture often highlighting and intensifying the emotion expressed in the face and voice. © 2014 John Wiley & Sons, Ltd.

    Affective dependency is characterized by emotional distress (insecure attachment) and dependency to another person with a low self-esteem and reassurance need. The paper proposes a reflection on the definition of emotional dependency and the confusion caused by various denominations. Overprotective and authoritarian parenting, cultural and socio-environmental factors may contribute to the development of dependent personality. Psychological epigenetic factors, such as early socio-emotional trauma could on neuronal circuits in prefronto-limbic regions that are essential for emotional behaviour.We also focus on the interrelations between dependent personality, domestic violence and addictions. The objective for the clinician is to propose a restoration of self-esteem and therapeutic strategies focused on autonomy.

    The human body is the object upon which medicine is acting, but also lived reality, image, symbol, representation and the object of elaboration and theory. All these elements which constitute the body influence the way medicine is treating it. In this series of three articles, we address the human body from various perspectives: medical (1), phenomenological (2), psychosomatic and socio-anthropological (3). This first article discusses four distinct types of representation of the body within medicine, each related to a specific epistemology and shaping a distinct kind of clinical legitimacy: the body-object of anatomy, the body-machine of physiology, the cybernetic body of biology, the statistical body of epidemiology.

    Body shape (BSP) and body image (BI) are part of the external physical structure, then modifications in body shape necessarily affect body image; however, both combined have not been studied. The purpose of the study was to evaluate the statistical relationship between BSP and BI in university students. Two hundred and ninety-six participants (17-35 years) were included in this study. Different anthropometric measurements were used to define their somatotype (BSP), body mass index (BMI), waist to hip ratio (WHR) and waist circumference (WC). In addition, a questionnaire on body image perception was applied (McElhone et al.), regarding "how do I look?", "how do I think others see me?", "how do others see me?", and "how do I want to look like?". On average, men perceived themselves in normal weight; in contrast, women perceived themselves as overweight. Men were meso-endomorphic, while women were endo-mesomorphic as an average. Body shape measured as somatotype as well as WC and WHR were excellent determinants of body image. Participants who presented a higher endomorphy, WC and WHR and a lower ectomorphy had a higher appreciation of being overweight or obese and wish to become thinner.

    Touches on one hand or forearm can affect tactile sensitivity at contralateral locations on the opposite side of the body. These interactions suggest an intimate connection between the two sides of the body. Here, we explore the effect of masking not across the body but through the body by measuring the effect of a masking stimulus on the back on the tactile sensitivity of the corresponding point on the front. Tactile sensitivity was measured on each side of the stomach, while vibrotactile masking stimulation was applied to one side of the front and to points on the back including the point directly behind the test point on the front. Results were compared to sensitivity, while vibrotactile stimulation was applied to a control site on the shoulder. A reduction in sensitivity of about .8 dB was found that required the masking stimulus to be within about 2 cm of the corresponding point on the back.

Looking at new tendencies within interaction design and ubiquitous computing to see...... how these are to an increasing extent focusing on sociality, context-awareness, relations, affects, connectedness and collectivity, we will examine how these new technological movements can change our perception of embodiment towards a distributed and shared one. By examining interactive textiles...... as part of a future rising landscape of multi-sensory networks, we will exemplify how the new technologies can shutter dichotomies and challenge traditional notions of embodiment and the subject. Finally, we show how this 'new embodiment' manifests Deleuze's philosophy of the body as something unstable...

    Full Text Available Multisensory integration must stand out among the fields of research that have witnessed a most impressive explosion of interest this last decade. One of these new areas of multisensory research concerns emotion. Since our first exploration of this phenomenon (de Gelder et al., 1999 a number of studies have appeared and they have used a wide variety of behavioral, neuropsychological and neuroscientifc methods. The goal of this presentation is threefold. First, we review the research on audiovisual perception of emotional signals from the face and the voice followed by a report or more recent studies on integrating emotional information provided by the voice and whole body expressions. We will also include some recent work on multisensory music perception. In the next section we discuss some methodological and theoretical issues. Finally, we will discuss findings about abnormal affective audiovisual integration in schizophrenia and in autism.

  5. Factors Affecting Wound Healing

    2010-01-01

    Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. For a wound to heal successfully, all four phases must occur in the proper sequence and time frame. Many factors can interfere with one or more phases of this process, thus causing improper or impaired wound healing. This article reviews the recent literature on the most significant factors that affect cutaneous wound healing and the potential cellular and/or molecular mechanisms involved. The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds. PMID:20139336

    Full Text Available Eating disorders should be understood in a multidimensional perspective, emphasizing a biopsicossocial context. In these pathologies it`s the body, in the first instance, that reveals the disease, being in this way the target of the conflict, revealing a disturbed body experience and as a consequence a weak conception of their personal body image. The body image is conceptualised as a subjective image that the individuals form in their own mind, about their body, in relation with differ- ent contexts of life. The intent of the studies is to comprehend the level of body image disturbance, which have concluded that in the majority of the cases, significant changes on perceptive capacity of the patients do not exist. In this way it`s important to study in a more effective and qualitative way the affective and personal factors. The authors pretend with this bibliographic revision, make a research of body image assessment to the Eating Disorders (Anorexia Nervosa and Bulimia Nervosa, and to reflect which are the best ones to adapt for Portuguese reality.

    López-Ibor, Juan J; Ortiz, Tomás; López-Ibor, María I

    2011-12-01

    Physician has to know the patient in the disease and not only the disease in the patient, from the dual perspective of the body as object and the body as subject. This also affects the patient who has to cope with the reality of having a body that bursts into the subject's consciousness as a vital threat, as source of discomfort and inability and being a body (Marcel). The human body in its dual aspect has been and is a great unknown, if not a great outrage in spite of the fact that we are our body and our body is each of us. We sometimes do not feel as we are and thus a confrontation arises, sometimes more normal, others more morbid. This forces the physician to face complex ethics considerations and the scientist to accept a personal identity disorder. Dualism considers that there are two substances in us, one that distinguishes us from other beings and from the rest of the individuals of the human species, the soul, the psychic life, mind or consciousness, and another more insubstancial one, the body. The aim of the first substance is to dominate the body, to survive it after death when it is, already a corpse is meant to become putrefied, is buried, incinerated or thrown to the depth of the sea. This dualism aims to explain the origin of the evil and the attitude to defeat it and it does so efficiently. This anthropology has very ancient roots (the Upvanishads, in the orphic texts, in Plato), it is the core of Gnostic thought and the foundation of the modern science since Descartes. Some monist perspectives are a masked dualism or a mereologic fallacy, according to which, the brain is conscious, when that what is conscious is the subject, although the subject, with the brain could not be conscious. Therefore, a new perspective is proposed, chiasmatic or janicular monism, that considers the adaptive value of focusing on the reality from two perspectives, as physical universe and the world of interpersonal relationships.

    2016-10-01

    Dissatisfaction with physical appearance and body image is a common psychological phenomena in Western society. Body image dissatisfaction is frequently reported by those who have excess body weight, but also is seen in those of normal body weight. For both groups of individuals, this dissatisfaction impacts self-esteem and quality of life. Furthermore, it is believed to be the motivational catalyst to a range of appearance-enhancing behaviors, including weight loss efforts and physical activity. Body image dissatisfaction is also believed to play a role in the decision to seek the wide range of body contouring procedures offered by aesthetic physicians. Individuals who seek these procedures typically report increased body image dissatisfaction, focus on the feature they wish to alter with treatment, and often experience improvement in body image following treatment. At the same time, extreme body image dissatisfaction is a symptom of a number of recognized psychiatric disorders. These include anorexia nervosa, bulimia nervosa, and body dysmorphic disorder (BDD), all of which can contraindicate aesthetic treatment. This special topic review paper provides an overview of the relationship between body image dissatisfaction and aesthetic procedures designed to improve body contouring. The review specifically focuses on the relationship of body image and body weight, as well as the presentation of body image psychopathology that would contraindicate aesthetic surgery. The overall goal of the paper is to highlight the clinical implications of the existing research and provide suggestions for future research on the psychological aspects of body contouring procedures. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

These significant memories are expressed in affect and through our bodily movements and gestures. Such body memories are unconscious non-symbolized patterns of self-in-relationship. Several methods of a body centered psychotherapy are described and clinical case examples illustrate the use of expressive methods within a relational psychotherapy.

    The aim of this study was to examine the relationship of semen parameters, sexual function-related hormones and waist/hip ratio. Eighty-one selected patients presenting with infertility were examined. Weight, height, waist circumference and hip circumference were measured, and reproduction-related hormone levels were determined. Semen was analysed by conventional methods. Semen volume, sperm concentration, motility, total sperm count, total motile sperm cell number, rapid progressive motile sperm count and reproduction-related hormone levels [follicle-stimulating hormone, luteinizing hormone, prolactin, testosterone, 17beta-oestradiol and sexual hormone-binding globulin (SHBG)]. Significant correlations were found: (i) weight, waist circumference and hip circumference versus testosterone level, SHBG level, and testosterone/17beta-oestradiol ratio; (ii) hip circumference versus sperm concentration; (iii) waist circumference and hip circumference versus sperm count, total motile sperm cell number and rapid progressive motile sperm count; (iv) weight versus total sperm count and total motile sperm cell number; (v) waist circumference and hip circumference versus prolactin level (positively) and SHBG (negatively); (vi) waist circumference and waist/hip ratio versus semen volume. It can be concluded that the waist/hip ratio is correlated with the reproductive hormone levels. Although both the waist circumference and hip circumference correlated with the semen characteristics, the waist/hip ratio did not.

    Body dysmorphic disorder (BDD) is a relatively common disorder with a point prevalence of 0.7-2.4 %. BDD is characterized by the patient's excessive concern with an imagined or slight defect in physical appearance. BDD usually begins in adolescence. Comorbidity rates and also suicidality rates are high. The course of BDD tends to be chronic. According to the present state of knowledge, cognitive-behavioral therapy and pharmacotherapy with selective serotonin reuptake inhibitors are valuable options in the therapy of BDD. The case report describes a recent case of BDD with typical clinical and therapy-related characteristics. The aim of this work is to strengthen the awareness of BDD in clinical practice of child and adolescent psychiatry, facilitating an adequate diagnosis and treatment of the affected individuals.

  15. Barthes's Body of Knowledge

    Full Text Available Roland Barthes invites a reading of his own texts in terms of the same methodologies he employs in his criticism. The «Biographeme»—those few details, preferences, inflections—which Barthes identified in his favorite authors, may be sought in Barthes as well. Barthes's biographeme, for me, consists of a glutinous effect associated with the organs of the mouth and throat as presented in several images, some of which belong to his tutor texts (Poe and Réquichot. An analysis of this biographeme reveals Barthes's strategy for disseminating the subject of knowledge—the author's fantasmatic body—through the signifiers of writing, fusing the heterogeneous singularities of the knower and the object of study. The metaphorical discourse that results opposes normal academic preoccupations in favor of knowledge of/as desire. Knowledge itself in Barthes becomes a second order signifier caught up in a catachretic process for naming the real. Barthes's procedure for exploring the real affectively, in terms of the body as it is defined in psychoanalysis, imposes on the reader a similar obligation to bring his or her own body into play in the learning experience. Barthes offers a model for a new genre of academic writing, combining science with autobiography, that has important implications for teaching and research in the humanities and social sciences.

    "Body" is a basic concept of both the natural and human sciences. This extensive review of the literature explores the various philosophical approaches to the body, including empiricism, idealism, existentialism and phenomenology, as well as the relationship between body and mind. Embodiment and body image are the two main concepts of body addressed in this article. Merleau-Ponty's perspective on embodiment, an important new area of theory development, emphasizes that embodiment research must focus on life experiences, such as the study of body image. Using Schilder's framework of psychosocialology, this article provides a comprehensive understanding of the concept of body image and women's perspectives on the "body" in both Western culture and Eastern cultures. Body size and shape significantly influence the self-image of women. Body image is something that develops and changes throughout one's life span and is continually being constructed, destructed, and reconstructed. Personal body image has important psychological effects on the individual, especially women. This integrative review can make a significant contribution to knowledge in this area and, consequently, to related practice and research.

  2. How our body influences our perception of the world

    Laurence Roy Harris

    2015-06-01

    Full Text Available Incorporating the fact that the senses are embodied is necessary for an organism to interpret sensory information. Before a unified perception of the world can be formed, sensory signals must be processed with reference to body representation. The various attributes of the body such as shape, proportion, posture, and movement can be both derived from the various sensory systems and can affect perception of the world (including the body itself. In this review we examine the relationships between sensory and motor information, body representations, and perceptions of the world and the body. We provide several examples of how the body affects perception (including but not limited to body perception. First we show that body orientation effects visual distance perception and object orientation. Also, visual-auditory crossmodal-correspondences depend on the orientation of the body: audio high frequencies correspond to a visual up defined by both gravity and body coordinates. Next, we show that perceived locations of touch is affected by the orientation of the head and eyes on the body, suggesting a visual component to coding body locations. Additionally, the reference-frame used for coding touch locations seems to depend on whether gaze is static or moved relative to the body during the tactile task. The perceived attributes of the body such as body size, affect tactile perception even at the level of detection thresholds and two-point discrimination. Next, long-range tactile masking provides clues to the posture of the body in a canonical body schema. Finally, ownership of seen body parts depends on the orientation and perspective of the body part in view. Together, all of these findings demonstrate how sensory and motor information, body representations, and perceptions (of the body and the world are interdependent.

    Directory of Open Access Journals (Sweden)

    Dhafer Ben Arbia

    2017-07-01

    Full Text Available Wearable wireless networks (WWNs offer innovative ways to connect humans and/or objects anywhere, anytime, within an infinite variety of applications. WWNs include three levels of communications: on-body, body-to-body and off-body communication. Successful communication in on-body and body-to-body networks is often challenging due to ultra-low power consumption, processing and storage capabilities, which have a significant impact on the achievable throughput and packet reception ratio as well as latency. Consequently, all these factors make it difficult to opt for an appropriate technology to optimize communication performance, which predominantly depends on the given application. In particular, this work emphasizes the impact of coarse-grain factors (such as dynamic and diverse mobility, radio-link and signal propagation, interference management, data dissemination schemes, and routing approaches directly affecting the communication performance in WWNs. Experiments have been performed on a real testbed to investigate the connectivity behavior on two wireless communication levels: on-body and body-to-body. It is concluded that by considering the impact of above-mentioned factors, the general perception of using specific technologies may not be correct. Indeed, for on-body communication, by using the IEEE 802.15.6 standard (which is specifically designed for on-body communication, it is observed that while operating at low transmission power under realistic conditions, the connectivity can be significantly low, thus, the transmission power has to be tuned carefully. Similarly, for body-to-body communication in an indoor environment, WiFi IEEE 802.11n also has a high threshold of end-to-end disconnections beyond two hops (approximatively 25 m. Therefore, these facts promote the use of novel technologies such as 802.11ac, NarrowBand-IoT (NB-IoT etc. as possible candidates for body-to-body communications as a part of the Internet of humans concept.

    Giummarra, Melita J; Bradshaw, John L; Nicholls, Michael E R; Hilti, Leonie M; Brugger, Peter

    2011-12-01

    Body integrity identity disorder (BIID) is characterised by profound experience of incongruity between the biological and desired body structure. The condition manifests in "non-belonging" of body parts, and the subsequent desire to amputate, paralyse or disable a limb. Little is known about BIID; however, a neuropsychological model implicating right fronto-parietal and insular networks is emerging, with potential disruption to body representation. We argue that, as there is scant systematic research on BIID published to date and much of the research is methodologically weak, it is premature to assume that the only process underlying bodily experience that is compromised is body representation. The present review systematically investigates which aspects of neurological processing of the body, and sense of self, may be compromised in BIID. We argue that the disorder most likely reflects dysregulation in multiple levels of body processing. That is, the disunity between self and the body could arguably come about through congenital and/or developmental disruption of body representations, which, together with altered multisensory integration, may preclude the experience of self-attribution and embodiment of affected body parts. Ulimately, there is a need for official diagnostic criteria to facilitate epidemiological characterisation of BIID, and for further research to systematically investigate which aspects of body representation and processing are truly compromised in the disorder.

  12. The Naked Truth: The Face and Body Sensitive N170 Response Is Enhanced for Nude Bodies

    Science.gov (United States)

    Hietanen, Jari K.; Nummenmaa, Lauri

    2011-01-01

    Recent event-related potential studies have shown that the occipitotemporal N170 component - best known for its sensitivity to faces - is also sensitive to perception of human bodies. Considering that in the timescale of evolution clothing is a relatively new invention that hides the bodily features relevant for sexual selection and arousal, we investigated whether the early N170 brain response would be enhanced to nude over clothed bodies. In two experiments, we measured N170 responses to nude bodies, bodies wearing swimsuits, clothed bodies, faces, and control stimuli (cars). We found that the N170 amplitude was larger to opposite and same-sex nude vs. clothed bodies. Moreover, the N170 amplitude increased linearly as the amount of clothing decreased from full clothing via swimsuits to nude bodies. Strikingly, the N170 response to nude bodies was even greater than that to faces, and the N170 amplitude to bodies was independent of whether the face of the bodies was visible or not. All human stimuli evoked greater N170 responses than did the control stimulus. Autonomic measurements and self-evaluations showed that nude bodies were affectively more arousing compared to the other stimulus categories. We conclude that the early visual processing of human bodies is sensitive to the visibility of the sex-related features of human bodies and that the visual processing of other people's nude bodies is enhanced in the brain. This enhancement is likely to reflect affective arousal elicited by nude bodies. Such facilitated visual processing of other people's nude bodies is possibly beneficial in identifying potential mating partners and competitors, and for triggering sexual behavior. PMID:22110574

    Lombardi, Riccardo; Pola, Marisa

    2010-12-01

    This article explores aspects of the clinical development of a male 17 year-old patient who had four weekly sessions of psychoanalysis during an acute psychotic crisis. In the context of arrested adolescent development, a psychotic crisis can present an opportunity to set the process of maturation in motion again. Adolescent psychosis is examined in the light of Bion's theories of catastrophic change - in which the container/contained relationship becomes explosive and overwhelming - as well as of Ferrari's and Matte Blanco's hypotheses on the mind-body relationship. The authors emphasize the role of denial of the body and its changes in the genesis of adolescent psychotic conflict, and show how the analytic relationship can offer crucial reverie conditions for promoting recognition of the body, bodily sensations and affects, as a prerequisite for the activation of an autonomous mental system. This clinical approach entails recognizing the urgent need to make room for the elaboration of intrasubjective relationships and for mind-body dialogue, transference interpretations being postponed. Clinical material and fragments of analytic dialogue illustrate the authors' hypotheses and demonstrate the patient's development towards recognition of his body and an incipient capacity to think associated with the perception of the limits set by time and reality.

    Full Text Available bjectives: This article approaches the problem of body language, in the new context ofonline communication, trying to see how the latestdevelopment of technology influences it.PriorWork: The interest in body language has grown in the last decades, first because of the work ofscientists like Ekman, who studied micro-gestures and tried to give a universaldecoder,and secondbecause of the latest technological evolution in communication, that has stressed the importance ofnon-verbal cues.Approach: Using observation and the latest writing in the field, we will explain theconsequences that the use of avatars and online communication have on body language and itsinterpretation.Results:Excluding context, posture, micro-gestures, tone and so on, onlinecommunication does not only become stereotype, butalso affects real communication and especiallybody language. We can observe pragmatism of gestures, standardizations, lack of customizations,inability to read other’s body language etc.Implications:All of this shapes the Y-Generation, onethat not only fails to interpret other’s body language, but also is unable to express themselves in directcommunication.Value:This paper stresses out not only the consequencesof online communication,but also the importance of further technological development.

  15. What can bodies do? Bodies and caves in the Karst Neolithic

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available This paper discuses ways in which bodies – human and animal – were produced in the Neolithic of the Karst. Bodies are seen as cumulative processes shaped by forces of encounters with the material world, rather than as biological givens. Thus, the paper focuses on the process of embodiment mediated with other bodies and landscape, especially important places such as caves. It explores the unique ways in which caves affect bodies, and how these affected bodies created new societies. In the Neolithic Karst, everyday contacts and interactions between humans, animals, the landscape and caves and rock shelters profoundly changed all the participants. A new hybrid society emerged, consisting of human and non-human bodies.

    A lower core body temperature set point has been suggested to be a factor that could potentially predispose humans to develop obesity. We tested the hypothesis that obese individuals have lower core temperatures than those in normal-weight individuals. In study 1, nonobese [body mass index (BMI; in kg/m(2)) temperature-sensing capsules, and we measured core temperatures continuously for 24 h. In study 2, normal-weight (BMI of 18-25) and obese subjects swallowed temperature-sensing capsules to measure core temperatures continuously for ≥48 h and kept activity logs. We constructed daily, 24-h core temperature profiles for analysis. Mean (±SE) daily core body temperature did not differ significantly between the 35 nonobese and 46 obese subjects (36.92 ± 0.03°C compared with 36.89 ± 0.03°C; P = 0.44). Core temperature 24-h profiles did not differ significantly between 11 normal-weight and 19 obese subjects (P = 0.274). Women had a mean core body temperature ≈0.23°C greater than that of men (36.99 ± 0.03°C compared with 36.76 ± 0.03°C; P body temperature. It may be necessary to study individuals with function-altering mutations in core temperature-regulating genes to determine whether differences in the core body temperature set point affect the regulation of human body weight. These trials were registered at clinicaltrials.gov as NCT00428987 and NCT00266500.

  17. Innocent Body-Shadow Mimics Physical Body

    Directory of Open Access Journals (Sweden)

    Kenri Kodaka

    2017-04-01

    Full Text Available The paradigm of the rubber hand illusion was applied to a shadow to determine whether the body-shadow is a good candidate for the alternative belonging to our body. Three kinds of shadows, a physical hand, a hand-shaped cloth, and a rectangle cloth, were tested for this purpose. The questionnaire results showed that both anatomical similarity and visuo-proprioception correlation were effective in enhancing illusory ownership of the shadow. According to the proprioceptive drift measurement, whether the shadow purely originated from the physical body was a critical factor in yielding the significantly positive drift. Thus, results demonstrated that the shadow can distort illusory ownership with the rubber hand illusion paradigm, but the proprioception was clearly distorted only when the body-shadow was purely applied. This implies the presence of special cognitive processing to discriminate the self-body shadow from the others.

  2. Relationships amongst body dissatisfaction, internalisation of the media body ideal and perceived pressure from media in adolescent girls and boys.

    Knauss, Christine; Paxton, Susan J; Alsaker, Françoise D

    2007-12-01

    Sociocultural factors that underpin gender differences in body dissatisfaction have not frequently been explored. We examined the relative contribution of internalization of media body ideals and perceived pressure to achieve this ideal in explaining body dissatisfaction in adolescent boys and girls. A sample of 819 boys and 791 girls completed measures of internalization of body ideals, perceived pressure, body mass index (BMI) and body dissatisfaction. As expected, girls showed higher body dissatisfaction, internalization and pressure than boys. Internalization, pressure and BMI contributed to the prediction of body dissatisfaction in boys and in girls although these variables explained less variance in body dissatisfaction in boys. In addition, for girls the strongest predictor of body dissatisfaction was internalization, whilst for boys the strongest predictor was pressure. Differences in extent of internalization and pressure may contribute to higher body dissatisfaction in girls than boys. These sociocultural factors may affect girls and boys differently.

    It is well known that body composition can influence peripheral heat loss and skin temperature. That the distribution of body fat is affected by gender is well known; however, there is little information on how body composition and gender influences the measure of skin temperature. This study evaluated skin temperature distribution according to body fat percentage (BF%) and gender. A sample of 94 apparently healthy volunteers (47 women and 47 men) was assessed with Dual-Energy X-Ray Absorptiometry (DXA) and infrared thermography (mean, maximum and minimum temperatures - T Mean , T Max and T Min ). The sample was divided into groups, according to health risk classification, based on BF%, as proposed by the American College of Sports Medicine: Average (n = 58), Elevated (n = 16) or High (n = 20). Women had lower T Mean in most regions of interest (ROI). In both genders, group High had lower temperature values than Average and Elevated in the trunk, upper and lower limbs. In men, palms and posterior hands had a tendency (p temperature along with increased BF%. T Mean , T Max and T Min of trunk, upper and lower limbs were negatively correlated with BF% and the fat percentage of each segment (upper limbs, lower limbs and trunk). The highest correlations found in women were between posterior trunk and BF% (rho = -0.564, p temperature than men, which was related with higher BF%. Facial temperature seems not to be influenced by body fat. With the future collection of data on the relationship between BF% and skin temperature while taking into account factors such as body morphology, gender, and ethnicity, we conclude that measurement of BF may be reliably estimated with the use of thermal imaging technology.

  4. Body mass modulates huddling dynamics and body temperature profiles in rabbit pups.

    Bautista, Amando; Zepeda, José Alfredo; Reyes-Meza, Verónica; Féron, Christophe; Rödel, Heiko G; Hudson, Robyn

    Altricial mammals typically lack the physiological capacity to thermoregulate independently during the early postnatal period, and in litter-bearing species the young benefit strongly from huddling together with their litter siblings. Such litter huddles are highly dynamic systems, often characterized by competition for energetically favorable, central positions. In the present study, carried out in domestic rabbits Oryctolagus cuniculus, we asked whether individual differences in body mass affect changes in body temperature during changes in the position within the huddle. We predicted that pups with relatively lower body mass should be more affected by such changes arising from huddle dynamics in comparison to heavier ones. Changes in pups' maximum body surface temperature (determined by infrared thermography) were significantly affected by changes in the number of their neighbors in the litter huddle, and indeed these temperature changes largely depended on the pups' body mass relative to their litter siblings. Lighter pups showed significant increases in their maximum body surface temperature when their number of huddling partners increased by one or two siblings whereas pups with intermediate or heavier body mass did not show such significant increases in maximum body temperature when experiencing such changes. A similar pattern was found with respect to average body surface temperature. This strong link between changes in the number of huddling partners and body surface temperature in lighter pups might, on the one hand, arise from a higher vulnerability of such pups due to their less favorable body surface area-to-volume ratio. On the other hand, as lighter pups generally had fewer neighbors than heavier ones and thus typically a comparatively smaller body surface in contact with siblings, they potentially had more to gain from increasing their number of neighbors. The present findings might help to understand how individual differences in body mass within a

    Full Text Available Abstract: Despite the importance of body satisfaction on one’s self image and well-being, little has been written about body image or how it affects people in Iran. The aim of this study is to assess body dissatisfaction and its risk factors in the general Iranian population. The sample size for this cross-sectional study included approximately 1,200 participants (both male and female and was conducted in 2011. Body dissatisfaction (based on the Figure Rating Scale, demographic characteristics, socioeconomic status, body mass index (BMI and use of the media were recorded. Nearly two thirds of the participants were included in the middle age group and roughly half of them had a university education. Approximately two thirds of the participants were satisfied with their body. The mean score of body dissatisfaction in women was greater than men (p < 0.0001. Age, gender, marital status and BMI had a significant relationship with body dissatisfaction. The finding of this study demonstrates that in Iran, body dissatisfaction and it consequences must be addressed. While the prevalence and pattern of body dissatisfaction in Iran is as high as other Asian countries, considering cultural variation within Asian countries is also important.

  16. Illusory Changes in Body Size Modulate Body Satisfaction in a Way That Is Related to Non-Clinical Eating Disorder Psychopathology

    Science.gov (United States)

    Preston, Catherine; Ehrsson, H. Henrik

    2014-01-01

    Historically, body size overestimation has been linked to abnormal levels of body dissatisfaction found in eating disorders. However, recently this relationship has been called into question. Indeed, despite a link between how we perceive and how we feel about our body seeming intuitive, until now lack of an experimental method to manipulate body size has meant that a causal link, even in healthy participants, has remained elusive. Recent developments in body perception research demonstrate that the perceptual experience of the body can be readily manipulated using multisensory illusions. The current study exploits such illusions to modulate perceived body size in an attempt to influence body satisfaction. Participants were presented with stereoscopic video images of slimmer and wider mannequin bodies viewed through head-mounted displays from first person perspective. Illusory ownership was induced by synchronously stroking the seen mannequin body with the unseen real body. Pre and post-illusion affective and perceptual measures captured changes in perceived body size and body satisfaction. Illusory ownership of a slimmer body resulted in participants perceiving their actual body as slimmer and giving higher ratings of body satisfaction demonstrating a direct link between perceptual and affective body representations. Change in body satisfaction following illusory ownership of a wider body, however, was related to degree of (non-clinical) eating disorder psychopathology, which can be linked to fluctuating body representations found in clinical samples. The results suggest that body perception is linked to body satisfaction and may be of importance for eating disorder symptomology. PMID:24465698

    Full Text Available Patients with anorexia nervosa (AN have a persistent distorted experience of the size of their body. Previously we found that the Rubber Hand Illusion improves hand size estimation in this group. Here we investigated whether a Full Body Illusion (FBI affects body size estimation of body parts more emotionally salient than the hand. In the FBI, analogue to the RHI, participants experience ownership over an entire virtual body in VR after synchronous visuo-tactile stimulation of the actual and virtual body.We asked participants to estimate their body size (shoulders, abdomen, hips before the FBI was induced, directly after induction and at ~2 hour 45 minutes follow-up. The results showed that AN patients (N = 30 decrease the overestimation of their shoulders, abdomen and hips directly after the FBI was induced. This effect was strongest for estimates of circumference, and also observed in the asynchronous control condition of the illusion. Moreover, at follow-up, the improvements in body size estimation could still be observed in the AN group. Notably, the HC group (N = 29 also showed changes in body size estimation after the FBI, but the effect showed a different pattern than that of the AN group.The results lead us to conclude that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts. As such this study offers novel starting points from which new interventions for body image disturbance in AN can be developed.

    Full Text Available Today, the juxtaposition between physical bodies and the gameworld is ever more fluid. Virtual Reality headsets are available at game stores with more AAA games being created for the format. The release of the Nintendo Switch and its dynamic JoyCon controllers reintroduce haptic movement based controls.  Pokémon GO’s augmented reality took gamers outdoors and has encouraged the Harry Potter franchise to follow in its mobile footsteps. Each development encourages a step further into the digital world. At the same time, the movement of bodies always has political dimensions. We live in a world where walls seem like solutions to the movement of bodies, while the mere meeting of bodies elsewhere – for sex, marriage and other reasons – is still forbidden by many states’ rules. Games and game-like interfaces have shown the ability to bend those rules, and to sometimes project other worlds and rule systems over our world in order to make bodies move and meet. For this special issue on ‘Body Movements’, Press Start invited authors to focus on embodiment, body movements, political bodies, community bodies, virtual bodies, physical bodies, feminine, masculine, trans- bodies, agency or its lack, and anything else in between. The response to this invitation was variegated, and provocative, as outlined here.

    Repeated exposures to thin-idealized body shapes may alter women's perceptions of what normal (e.g., accepted) and ideal (e.g., desired) bodies in a cultural environment look like. The aim of the present study was to investigate whether exposure to thin and round body shapes may change the subsequent esthetic appreciation of others' bodies and the perceptual and cognitive-affective dimensions of self-body image in patients suffering from anorexia nervosa (AN). Thirteen AN patients and 13 matched healthy controls were exposed to pictures of either thin or round unfamiliar body models and, before and after exposure, they were required to either express liking judgments about round and slim figures of unfamiliar bodies (esthetic task) or to adjust distorted pictures of their own body to their perceptual (How do you see yourself?), affective (How do you feel yourself?), metacognitive (How do others see you?) and ideal (How would you like to look like?) body image (self-body adjustment task). Brief exposures to round models increased liking judgments of round figures in both groups. However, only in AN patients, exposure to round models induced an increase in thin figures liking, which positively correlated with their preoccupation with dieting. Furthermore, exposure to round bodies in AN patients, but not in controls, increased the distortion for the perceptual body image and decreased the size of the ideal one. No differences between the two groups were obtained after adaptation to thin models. Our results suggest that AN patients' perception of their own and others' body is more easily malleable by exposure to round figures as compared to controls. Crucially, this mechanism may strongly contribute to the development and maintenance of self-body image disturbances.

    Full Text Available Emotions are currently at the center of a lively international and interdisciplinary debate. The first sections of this essay present a synthetic overview of its key features. The main sections provide a re-examination of one of the most historically significant developments in the field of affective studies. René Descartes’ approach to the study of emotions implies a positive assessment of the role of the body and a remarkable attenuation of his classical dualism that allows an innovative perspective on the subject. He inaugurated a new scientific style of research, which is one of the original sources of some key concepts of the current research.

  13. Determinants of variation in adult body height.

    Science.gov (United States)

    Silventoinen, Karri

    2003-04-01

    Final body height is achieved as the result of a combination of genetic and environmental factors. The aim of this article is to review past studies on body height that have followed different scientific traditions. In modern Western societies, about 20% of variation in body height is due to environmental variation. In poorer environments, this proportion is probably larger, with lower heritability of body height as well as larger socioeconomic body height differences. The role of childhood environment is seen in the increase in body height during the 20th century simultaneously with the increase in the standard of living. The most important non-genetic factors affecting growth and adult body height are nutrition and diseases. Short stature is associated with poorer education and lower social position in adulthood. This is mainly due to family background, but other environmental factors in childhood also contribute to this association. Body height is a good indicator of childhood living conditions, not only in developing countries but also in modern Western societies. Future studies combining different scientific traditions in auxology are needed to create a more holistic view of body height.

    Body image” is more than the visual perception of size and it is probably multidimensional. It is known to influence eating behaviors and self-esteem of adolescents. Although widely studied in developed countries, it has been studied little in Sri Lanka. This study was designed to translate and culturally adapt a tool to assess dimensions of body image in Sri Lankan adolescents. The study was carried out in the Anuradhapura District on school going children in grades nine to eleven. A multidimensional body image questionnaire was translated to Sinhalese language using the nominal group consensus method. The translated version was administered to 278 (114 boys) students after content validation and pre-testing. To assess test-retest reliability, the same questionnaire was administered to the same sample after two weeks. Psychometric properties were assessed using exploratory factor analysis. Three-factor model emerged when dimensions in body image were analysed. Both boys and girls had almost identical factor structure. The three dimensions identified were “affective body image”, “body perception” and “orientation on body size”. All factors had good internal consistency with Cronbach’s alpha > 0.76 and explained more than 56% of the total variance in both sexes. The translated body image questionnaire was a valid and reliable tool which can be used in Sri Lankan adolescents. Both genders had a similar, multidimensional body image construct.

  15. The Athletic Body.

    Science.gov (United States)

    Edgar, Andrew

    2016-09-10

    This paper seeks to explore the attraction and the beauty of the contemporary athletic body. It will be suggested that a body shaped through muscular bulk and definition has come to be seen as aesthetically normative. This body differs from the body of athletes from the early and mid-twentieth century. It will be argued that the contemporary body is not merely the result of advances in sports science, but rather that it is expressive of certain meanings and values. The visual similarity of the contemporary athletic body and that of the comic book superhero suggests that both bodies carry a similar potential for narrative story-telling, and that their attraction is bound up with this narrative potential. The superhero and athlete live meaningful lives, pursuing clear and morally unambiguous goals. The aesthetic attraction of the body lies in its capacity to facilitate the articulation of a story of a meaningful life, and to do so in the face of the growing anomie and thus meaninglessness of life as experienced in contemporary society. Athleticism offers an illusion of meaning, serving to reproduce dominant justificatory narratives and social stereotypes. Yet, as an illusion of meaning, it may be challenged and negotiated, not least with respect to its bias towards a certain form of the male body. The female athletic body disrupts the illusion, opening up new existential possibilities, new ways of living and being, and thus new, and potentially disruptive, narratives.

  17. Rubber hand illusion affects joint angle perception.

    Directory of Open Access Journals (Sweden)

    Martin V Butz

    Full Text Available The Rubber Hand Illusion (RHI is a well-established experimental paradigm. It has been shown that the RHI can affect hand location estimates, arm and hand motion towards goals, the subjective visual appearance of the own hand, and the feeling of body ownership. Several studies also indicate that the peri-hand space is partially remapped around the rubber hand. Nonetheless, the question remains if and to what extent the RHI can affect the perception of other body parts. In this study we ask if the RHI can alter the perception of the elbow joint. Participants had to adjust an angular representation on a screen according to their proprioceptive perception of their own elbow joint angle. The results show that the RHI does indeed alter the elbow joint estimation, increasing the agreement with the position and orientation of the artificial hand. Thus, the results show that the brain does not only adjust the perception of the hand in body-relative space, but it also modifies the perception of other body parts. In conclusion, we propose that the brain continuously strives to maintain a consistent internal body image and that this image can be influenced by the available sensory information sources, which are mediated and mapped onto each other by means of a postural, kinematic body model.

  1. Does body image influence the relationship between body weight and breastfeeding maintenance in new mothers?

    Swanson, Vivien; Keely, Alice; Denison, Fiona C

    2017-09-01

    Obese women have lower breastfeeding initiation and maintenance rates than healthy weight women. Research generally focuses on biomedical explanations for this. Psychosocial factors including body image and well-being after childbirth are less well understood as predictors of breastfeeding. In obese and healthy weight women, we investigated changes in body image between 72 hrs post-delivery and 6-8 weeks post-natal, studying how women's body image related to breastfeeding initiation and maintenance. We also investigated how psychological distress was related to body image. Longitudinal semi-structured questionnaire survey. Body image and psychological distress were assessed within 72 hrs of birth and by postal questionnaire at 6-8 weeks, for 70 obese and 70 healthy weight women initiating exclusive (breastmilk only) breastfeeding or mixed feeding (with formula milk) in hospital. Breastfeeding was re-assessed at 6-8 weeks. Obese women were less likely to exclusively breastfeed in hospital and maintain breastfeeding to 6-8 weeks. Better body image was related to maintaining breastfeeding and to lower post-natal psychological distress for all women, but education level was the most significant predictor of maintenance in multivariate regression including body image and weight status. Body image mediated, but did not moderate the relationship between weight and breastfeeding maintenance. Body image was lower overall in obese women, but all women had low body image satisfaction around childbirth, reducing further at 6-8 weeks. Health professionals should consider women's body image when discussing breastfeeding. A focus on breast function over form may support breastfeeding for all women. Statement of contribution What is already known on this subject? Obesity can negatively affect breastfeeding initiation and maintenance, but there is little information about how psychosocial factors affect this relationship. Body image may be an important factor, but has not

  2. No Effect of Featural Attention on Body Size Aftereffects

    Directory of Open Access Journals (Sweden)

    Ian David Stephen

    2016-08-01

    Full Text Available Prolonged exposure to images of narrow bodies has been shown to induce a perceptual aftereffect, such that observers’ point of subjective normality (PSN for bodies shifts towards narrower bodies. The converse effect is shown for adaptation to wide bodies. In low-level stimuli, object attention (attention directed to the object and spatial attention (attention directed to the location of the object have been shown to increase the magnitude of visual aftereffects, while object-based attention enhances the adaptation effect in faces. It is not known whether featural attention (attention directed to a specific aspect of the object affects the magnitude of adaptation effects in body stimuli. Here, we manipulate the attention of Caucasian observers to different featural information in body images, by asking them to rate the fatness or sex typicality of male and female bodies manipulated to appear fatter or thinner than average. PSNs for body fatness were taken at baseline and after adaptation, and a change in PSN (ΔPSN was calculated. A body size adaptation effect was found, with observers who viewed fat bodies showing an increased PSN, and those exposed to thin bodies showing a reduced PSN. However, manipulations of featural attention to body fatness or sex typicality produced equivalent results, suggesting that featural attention may not affect the strength of the body size aftereffect.

    Full Text Available Purpose. The aim of the study was to evaluate walking economy and physiological responses at two walking speeds in males with similar absolute body mass but different body composition. Methods. The study involved 22 young men with similar absolute body mass, BMI, aerobic performance, calf and thigh circumference. The participants differed in body composition: body fat (HBF group and lean body mass (HLBM group. In the graded test, maximal oxygen uptake (VO2max and maximal heart rate were measured. Walking economy was evaluated during two walks performed at two different speeds (4.8 and 6.0 km ‧ h-1. Results. The VO2max was similar in both groups, as were the physiological responses during slow walking. The absolute oxygen uptake or oxygen uptake relative to body mass did not significantly differentiate the studied groups. The only indicator significantly differentiating the two groups was oxygen uptake relative to LBM. Conclusions. Body composition does not significantly affect walking economy at low speed, while during brisk walking, the economy is better in the HLBM vs. HBF group, provided that walking economy is presented as oxygen uptake relative to LBM. For this reason, we recommend this manner of oxygen uptake normalization in the evaluation of walking economy.

    Psycharakis, Stelios G; Sanders, Ross H

    2010-02-01

    In this article, we present a critical review of the swimming literature on body roll, for the purposes of summarizing and highlighting existing knowledge, identifying the gaps and limitations, and stimulating further research. The main research findings can be summarized as follows: swimmers roll their shoulders significantly more than their hips; swimmers increase hip roll but maintain shoulder roll when fatigued; faster swimmers roll their shoulders less than slower swimmers during a 200-m swim; roll asymmetries, temporal differences in shoulder roll and hip roll, and shoulder roll side dominance exist in front crawl swimming, but there is no evidence to suggest that they affect swimming performance; and buoyancy contributes strongly to generating body roll in front crawl swimming. Based on and stimulated by current knowledge, future research should focus on the following areas: calculation of body roll for female swimmers and for backstroke swimming; differences in body roll between breathing and non-breathing cycles; causes of body roll asymmetries and their relation to motor laterality; body roll analysis across a wide range of velocities and swimming distances; exploration of the association between body roll and the magnitude and direction of propulsive/resistive forces developed during the stroke cycle; and the influence of kicking actions on the generation of body roll.

    2014-01-01

    There is a growing body of research indicating that bodily sensation and behavior strongly influences one's emotional reaction toward certain situations or objects. On this background, a framework model of embodied affectivity is suggested: we regard emotions as resulting from the circular interaction between affective qualities or affordances in the environment and the subject's bodily resonance, be it in the form of sensations, postures, expressive movements or movement tendencies. Motion and emotion are thus intrinsically connected: one is moved by movement (perception; impression; affection) and moved to move (action; expression; e-motion). Through its resonance, the body functions as a medium of emotional perception: it colors or charges self-experience and the environment with affective valences while it remains itself in the background of one's own awareness. This model is then applied to emotional social understanding or interaffectivity which is regarded as an intertwinement of two cycles of embodied affectivity, thus continuously modifying each partner's affective affordances and bodily resonance. We conclude with considerations of how embodied affectivity is altered in psychopathology and can be addressed in psychotherapy of the embodied self.

  8. Emotions, affects and the production of social life.

    Science.gov (United States)

    Fox, Nick J

    2015-06-01

    While many aspects of social life possess an emotional component, sociology needs to explore explicitly the part emotions play in producing the social world and human history. This paper turns away from individualistic and anthropocentric emphases upon the experience of feelings and emotions, attending instead to an exploration of flows of 'affect' (meaning simply a capacity to affect or be affected) between bodies, things, social institutions and abstractions. It establishes a materialist sociology of affects that acknowledges emotions as a part, but only a part, of a more generalized affective flow that produces bodies and the social world. From this perspective, emotions are not a peculiarly remarkable outcome of the confluence of biology and culture, but part of a continuum of affectivity that links human bodies to their physical and social environment. This enhances sociological understanding of the part emotions play in shaping actions and capacities in many settings of sociological concern. © London School of Economics and Political Science 2015.

    Bergsholm, P; Martinsen, E W; Holsten, F; Neckelmann, D; Aarre, T F

    1992-08-30

    Inadequate treatment of mood (affective) disorders is related to the mind/body dualism, desinformation about methods of treatment, the stigma of psychiatry, low funding of psychiatric research, low educational priority, and slow acquisition of new knowledge of psychiatry. The "respectable minority rule" has often been accepted without regard to the international expertise, and the consequences of undertreatment have not been weighed against the benefits of optimal treatment. The risk of chronicity increases with delayed treatment, and inadequately treated affective disorders are a leading cause of suicide. During the past 20 years the increase in suicide mortality in Norway has been the second largest in the world. Severe mood disorders are often misclassified as schizophrenia or other non-affective psychoses. Atypical mood disorders, notably rapid cycling and bipolar mixed states, are often diagnosed as personality, adjustment, conduct, attention deficit, or anxiety disorders, and even mental retardation. Neuroleptic drugs may suppress the most disturbing features of mood disorders, a fact often misinterpreted as supporting the diagnosis of a schizophrenia-like disorder. Treatment with neuroleptics is not sufficient, however, and serious side effects may often occur. The consequences are too often social break-down and post-depression syndrome.

    This study examines sociocultural influences affecting both body image and body change methods in adolescent boys. Twenty boys in grade 7 (aged 12-13) and twenty boys in grade 9 (aged 14-15) were individually interviewed. The influence of parents, siblings, friends and the media on both body image and body change methods was evaluated. For approximately a third of the boys, parents, siblings, friends and the media were perceived to have at least some influence over boys' feelings about their bodies and body change methods. In particular, feedback from mothers and female friends were viewed as having a positive impact on boys' body image whereas feed-back from fathers and male friends was viewed as more important in influencing body change methods. The media was also viewed as contributing to boys' body satisfaction but it was seen to encourage greater exercise to alter body size and shape. The differences and similarities between the sociocultural messages received by males and females are discussed. The implication of these findings in fostering better health among adolescent males are explored.

  20. Disorders of body temperature.

    Science.gov (United States)

    Gomez, Camilo R

    2014-01-01

    The human body generates heat capable of raising body temperature by approximately 1°C per hour. Normally, this heat is dissipated by means of a thermoregulatory system. Disorders resulting from abnormally high or low body temperature result in neurologic dysfunction and pose a threat to life. In response to thermal stress, maintenance of normal body temperature is primarily maintained by convection and evaporation. Hyperthermia results from abnormal temperature regulation, leading to extremely elevated body temperature while fever results from a normal thermoregulatory mechanism operating at a higher set point. The former leads to specific clinical syndromes with inability of the thermoregulatory mechanism to maintain a constant body temperature. Heat related illness encompasses heat rash, heat cramps, heat exhaustion and heat stroke, in order of severity. In addition, drugs can induce hyperthermia and produce one of several specific clinical syndromes. Hypothermia is the reduction of body temperature to levels below 35°C from environmental exposure, metabolic disorders, or therapeutic intervention. Management of disorders of body temperature should be carried out decisively and expeditiously, in order to avoid secondary neurologic injury. © 2014 Elsevier B.V. All rights reserved.

    A case of a 41-year-old patient presenting late post-trauma with out any major signs or symptoms is presented herewith. On radiological investigation, a peculiar foreign body was identified in the orbital floor. To our surprise the point of entry of the foreign body was not proportionate with the size of it. Moreover, the trajectory and final location of foreign body did not concur with the symptom less presentation of patient. After what was thought to be adequate investigation, the patient was taken under general anaesthesia to reveal an additional foreign body that put most of the preoperative queries to rest. This case in retrospect emphasises the need for ruling out foreign body in the case of any penetrating injury of orbit with the help of not just radiographs and CT scans but also ultrasonography and MRI.

    Full Text Available Orbital pseudotumor is a benign disease involving the orbital structures. Pseudotumor of the ciliary body is rare. We present a case of a 27-year-old male who presented with gradual visual loss, pain, and redness in his left eye. On examination he was found to have a yellowish white mass at the periphery of anterior chamber in his left eye and ultrasound biomicroscopy (UBM revealed a ciliary body mass in the same eye. He was treated with systemic steroids, which was tapered over a period of 8 weeks. His symptoms improved and the ciliary body mass disappeared with no recurrence over the next 6 months. UBM is an important diagnostic tool for diagnosing ciliary body mass. Early diagnosis and prompt treatment with systemic steroids may help resolve pseudotumor of the ciliary body.

    Nowadays, in developed countries there are standards of beauty based on pro-thin models, which are internalized by adolescents and young people especially in the case of women, assuming it as risk factor for developing changes in body image and perception. To analyze the current state of research in relation to body image, the sociodemographic variables that influence it, the relationship between body composition, conducting diets, eating disorders, sports and intervention programs and prevention, and the body image. It was searched in Medline, Isi Web of knowledge and Dialnet as well as a manual search among the references of selected studies and in different libraries. A increased socio-cultural influence is associated with a greater perception of body fat, greater body image dissatisfaction and lower self assessment of overall fitness. This leads to a lot of teenagers and young adults to abuse to the restrictive diets and to suffer eating disorders. Numerous studies have analyzed the relationship between sports practice with body image disturbance; there are conflictive results. Moreover it is necessary to design objective tools to detect changes and enhance the design of prevention and intervention programs in order to avoid distortion of body image, especially in those age ranges where the population is more vulnerable to this phenomenon. The excessive current preoccupation about body image has resulted in the realization of diets and changes as eating disorders. There are other factors that influence body image and perception as the realization of physical exercise, although the results about the relationship between these factors are contradictory. Therefore, further work is needed on the issue by creating tools to detect changes and enhance the design of prevention and intervention programs. Copyright © AULA MEDICA EDICIONES 2013.

  8. The body as art.

    2002-07-01

    For millennia people have altered the appearance of their bodies with cosmetics, jewellery, tattoos, piercings, and other surgical procedures. It would appear that they wish to conform to a perceived 'ideal body', although the actual appearance of such a body is subject to temporal, cultural and geographical change. In contemporary society the media are largely responsible for providing the yardsticks against which individual body shape is measured. Today the desired form is generally young, slim, tanned and blemish-free. Sadly, dissatisfaction with body image can be the source of great unhappiness and may even lead to suicide. Interested scholars have debated the meaning of beauty for centuries but it seems that every human society has its own standards. At the simplest it would appear that youth and symmetry are the most highly prized ingredients. There is no doubt that those who fit the conventional standards of attractiveness are treated better by society. Individuals have an inalienable right to their own body appearance, and to alter it as they see fit, however such modifications may not always be in their own best interests. Practitioners of cosmetic procedures must be alert to clients with histories of weight fluctuation, unrealistic body image, or low self-esteem. Psychological disorders may present with dysmorphophobic symptoms. Doctors providing cosmetic services need to be adept at diagnosing psychological illness.

    Full Text Available In the Fall of 2013 we team-taught a disability studies course for a small group of first-year students. The course, Minding the Body, integrated scholarship from disability studies, feminist/queer studies, psychology, and Russian Studies. Originally envisioned and taught independently in the Fall of 2012 by Joan Ostrove and focused entirely on the U.S., Anastasia Kayiatos's arrival in the Department of German and Russian Studies at Macalester College afforded us an opportunity for collaboration and co-instruction that we found invigorating, compelling, and transformative. Grounded from the outset in disability studies, the course asked students to interrogate such questions as: What is a "normal" body? A "beautiful" body? Why do we feel the way we do about our bodies? How are bodies objectified, exploited, and regulated? How and why do we discriminate against people with non-normative bodies? How do people represent the experience of having a disabled body? How can we think critically about the various ways in which people change, regulate, and enhance their bodies? How do sexism, racism, classism, colonialism, homophobia, transphobia and other forms of oppression influence how different bodies are viewed, treated, educated, and experienced? The integration of Russian Studies importantly allowed us to ask how these questions and ideas change when we travel across time and geographical space. In our paper we will reflect on our experience of co-authoring the syllabus (we will include both the solo-taught and co-taught versions of the syllabus in an appendix; outline some of our techniques for team-teaching; and analyze an exemplary assignment and class meeting. We will conclude with a final word about the unique forms of teaching and learning that happened in our class as a consequence of its collaborative and interdisciplinary approach, which opened up new perspectives in disability studies not only for our students but also for us.

    We report the case of FP affected by personal and extrapersonal neglect and a body representation deficit characterized by delusional ideas. When FP performed the human figure, he placed body parts to the left, despite his extrapersonal neglect. Differently, when he performed the car figure, he placed all parts to the right, in line with his deficit. Comparing FP with a small patient group with the same clinical features without delusional ideas about body emerged that he was the only one to suffer from a specific body representation deficit characterized by a lack of body ownership sense.

    Voelker, Dana K; Reel, Justine J; Greenleaf, Christy

    2015-01-01

    Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

    Conspicuous deficits in face recognition characterize prosopagnosia. Information on whether agnosic deficits may extend to non-facial body parts is lacking. Here we report the neuropsychological description of FM, a patient affected by a complete deficit in face recognition in the presence of mild clinical signs of visual object agnosia. His deficit involves both overt and covert recognition of faces (i.e. recognition of familiar faces, but also categorization of faces for gender or age) as well as the visual mental imagery of faces. By means of a series of matching-to-sample tasks we investigated: (i) a possible association between prosopagnosia and disorders in visual body perception; (ii) the effect of the emotional content of stimuli on the visual discrimination of faces, bodies and objects; (iii) the existence of a dissociation between identity recognition and the emotional discrimination of faces and bodies. Our results document, for the first time, the co-occurrence of body agnosia, i.e. the visual inability to discriminate body forms and body actions, and prosopagnosia. Moreover, the results show better performance in the discrimination of emotional face and body expressions with respect to body identity and neutral actions. Since FM's lesions involve bilateral fusiform areas, it is unlikely that the amygdala-temporal projections explain the relative sparing of emotion discrimination performance. Indeed, the emotional content of the stimuli did not improve the discrimination of their identity. The results hint at the existence of two segregated brain networks involved in identity and emotional discrimination that are at least partially shared by face and body processing.

    Multisensory integration is a powerful mechanism for constructing body awareness and key for the sense of selfhood. Recent evidence has shown that the specialised C tactile modality that gives rise to feelings of pleasant, affective touch, can enhance the experience of body ownership during multisensory integration. Nevertheless, no study has examined whether affective touch can also modulate psychological identification with our face, the hallmark of our identity. The current study used the ...

    When suggesting for discussion a possible role and the utility of an international body for an internationally monitored retrievable storage system (IMRSS), it appears useful to consider its possible advantages and disadvantages to also assess the potential of successfully implementing such a body in the medium or long term. To stimulate such discussion is the purpose of the remainder of this paper. Moreover, the question needs to be discussed whether there could be a unique format for an IMRSS governing body or various degrees of decentralization oriented, for example, at the physical locations of relevant IMRSS facilities. The main difficulties with solutions that include responsibilities of an international IMRSS body for property, right of use, safeguards, or other issues of a more legal and/or administrative nature are discussed

  9. Unusual orbital foreign bodies

    Directory of Open Access Journals (Sweden)

    Agarwal P

    1993-01-01

    Full Text Available Retained intraorbital organic foreign bodies, particularly wooden, are commonly encountered in ophthalmologic practice. We treated two children who had sustained such injury while playing. They presented to us with non-healing sinus with purulent discharge. In one of the patients, X-rays and CT scan helped to clinch the diagnosis, whereas in the other patient diagnosis was possible by correlating history with clinical findings. Surgical exploration in both patients helped us to remove the foreign bodies. Surprisingly, both the foreign bodies were 7 cm long wooden pieces. We, however, caution that management of such cases should be conservative and that surgical exploration be done only in case of complication. From our experience, we recommend proper localisation by all possible means, blunt dissection, careful haemostasis coupled with excellent lighting and exposure in the atraumatic removal of intraorbital foreign bodies.
