Infracommunity structure of parasites of Hemigymnus melapterus (Pisces : Labridae) from Lizard Island, Australia: The importance of habitat and parasite body size

This Study describes the community of all metazoan parasites from 14 individuals of thicklip wrasse, Hemigymnus melapterus, from Lizard Island, Australia. All fish were parasitized, and 4,649 parasite individuals were found. Twenty-six parasite species were identified although only 6 species were abundant and prevalent: gnathiid isopods, the copepod Hatschekia hemigymni, the digenean Callohelmis pichelinae, and 3 morphotypes of tetraphyllidean cestode larvae. We analyzed whether the body size and microhabitat of the parasites and size of the host affected understanding of the structure of the parasite community. We related the abundance, biovolume, and density of parasites with the host body size and analyzed the abundances and volumetric densities of some parasite species within microhabitats. Although the 2 most abundant species comprised 75% of all parasite individuals, 4 species, each in similar proportion, comprised 85% of the total biovolume. Although larger host individuals had higher richness, abundance, and biovolume of parasites than smaller individuals, overall parasite volumetric density actually decreased with the host body size. Moreover. parasites exhibited abundances and densities significantly different among microhabitats; some parasite species depended on the area available, whereas others selected a specific microhabitat. Parasite and habitat size exhibited interesting relationships that should be considered more frequently. Considerations of these parameters improve understanding of parasite community structure and how the parasites use their habitats.

Numerical evaluation of the fields induced by body motion in or near high-field MRI scanners

In modern magnetic resonance imaging, both patients and health care workers are exposed to strong. non-uniform static magnetic fields inside and outside of the scanner. In which body movement may be able to induce electric currents in tissues which could be potentially harmful. This paper presents theoretical investigations into the spatial distribution of induced E-fields in a tissue-equivalent human model when moving at various positions around the magnet. The numerical calculations are based on an efficient. quasi-static, finite-difference scheme. Three-dimensional field profiles from an actively shielded 4 T magnet system are used and the body model projected through the field profile with normalized velocity. The simulation shows that it is possible to induce E-fields/currents near the level of physiological significance under some circumstances and provides insight into the spatial characteristics of the induced fields. The methodology presented herein can be extrapolated to very high field strengths for the evaluation of the effects of motion at a variety of field strengths and velocities. (C) 2004 Elsevier Ltd.

Transmission ratio distortion in the human body louse, Pediculus humanus (Insecta : Phthiraptera)

We studied inheritance at three microsatellite loci in eight F-1 and two F-2 families of the body (clothes) louse of humans, Pediculus humanus. The alleles of heterozygous female-parents were always inherited in a Mendelian fashion in these families. Alleles from heterozygous male-parents, however, were inherited in two different ways: (i) in a Mendelian fashion and (ii) in a non-Mendelian fashion, where males passed to their offspring only one of their two alleles, that is, 100% nonrandom transmission. In male body lice, where there was non-Mendelian inheritance, the paternally inherited set of alleles was eliminated. We interpret this pattern of inheritance as evidence for extreme transmission ratio distortion of paternal alleles in this species.

The effect of whole body vibration on oxygen uptake and electromyographic signal of the rectus femoris muscle during static and dynamic squat

Whole Body Vibrations consist of a vibration stimulus mechanically transferred to the body. The impact of vibration treatment on specific muscular activity, neuromuscular, and postural control has been widely studied. We investigated whole body vibration (WBV) effect on oxygen uptake and electromyographic signal of the rectus femoris muscle during static and dynamic squat. Fourteen healthy subjects performed a static and dynamic squat with and without vibration. During the vibration exercises, a significant increase was found in oxygen uptake (P=0.05), which increased by 44% during the static squat and 29.4% during the dynamic squat. Vibration increased heart rate by 11.1 ± 9.1 beats.min-1 during the static squat and 7.9 ± 8.3 beats.min-1 during the dynamic squat. No significant changes were observed in rate of perceived exertion between the exercises with and without vibration. The results indicate that the static squat with WBV produced higher neuromuscular and cardiorespiratory system activation for exercise duration ?60 sec. Otherwise, if the single bout duration was higher than 60 sec, the greater cardiorespiratory system activation was achieved during the dynamic squat with WBV while higher neuromuscular activation was still obtained with the static exercise.

Estimation of the temperature of a radiating body by measuring the stationary temperatures of a thermometer placed at different distances

This paper presents a novel method for determining the temperature of a radiating body. The experimental method requires only very common instrumentation. It is based on the measurement of the stationary temperature of an object placed at different distances from the body and on the application of the energy balance equation in a stationary state. The method allows one to obtain the temperature of an inaccessible radiating body when radiation measurements are not available. The method has been applied to the determination of the filament temperature of incandescent lamps of different powers.

“My people seem to be falling to bits”: impotence, memory, and the co-possibility of body and mind in Samuel Beckett’s works

The present thesis examines the representation of the impotent body and mind in a selection of Samuel Beckett’s dramatic and prose works. Aiming to show that the body-mind relation is represented as one of co-implication and co-constitution, this thesis also takes the representation of memory in Beckett’s work as a key site for examining this relation. The thesis seeks to address the centrality of the body and embodied subjectivity in the experience of memory and indeed in signification and experience more generally. In these terms, Chapter 1 analyzes the representation of the figure of the couple in Beckett’s drama of the 1950s – as a metaphor of the body-mind relation – and, in light of Jacques Derrida’s theory of the supplement and Bernard Stiegler’s theory of technics, it discusses how the relationship between physical body and mind is defined by an essential supplementarity that is revealed even (or especially) in their apparent separation. Furthermore, the impotence that marks both elements in Beckett’s writings, when it is seen to lay bare this intrication, can be viewed, in important respects, as enabling rather than merely privative. Chapter 2 discusses the somatic structure of memory as represented in four of Beckett’s later dramatic works composed in the 1970s and 1980s. Similarly to Chapter 1, the second chapter focuses on the more “extreme” representation of bodily impotence in Beckett and demonstrates that rather than a merely “mental” recollection, memory in the work of Beckett is presented as necessarily experienced through, and shaped by, the body itself. In this light, then, it is shown that despite the impotence that marks the body in Beckett’s work of the 1970s and 1980s, the body is a necessary site of memory and retains or discovers a kind of activity in this impotence. Finally, Chapter 3 shifts its attention to Beckett’s prose works in order to explore how such works, reliant on language rather than the physical performance of actors onstage, sustain questions of embodied subjectivity at their heart. Specifically, the chapter argues that, on closer inspection, Beckett’s “literature of the unword” is not an abstention from meaning and its materialization, but one that paradoxically foregrounds that “something” which remains an essential part of it, that is, an embodied subjectivity.

Real, rubber or virtual: The vision of “one’s own” body as a means for pain modulation. A narrative review

In the last few years a branch of pain research has been focussing on the modulatory effects of the vision of the body on pain perception. So, for instance, the vision of one’s own real body has been proven to induce analgesic effects. On the other hand, bodily illusions such as the rubber hand illusion have provided new tools for the study of perceptual processes during altered body ownership states. Recently, new paradigms of body ownership made use of a technology that is going places both in clinical and in experimental settings, i.e. virtual reality. While the vision of one’s own real body has been proven to yield compelling analgesic effects, slightly more controversial are those attributed to the vision of “owned” dummy bodies. This review will discuss the studies that examined the effects on pain perception of the vision of the own body, with or without body ownership illusions.

Body image dissatisfaction and low self-esteem due to physical appeareance in students of the faculty of medicine at the university of los andes (mérida, venezuela)

The purpose of this investigation was to evaluate body image dissatisfaction in relation to low self-esteem due to physical appearance in students of the Faculty of Medicine at the University of Los Andes in Mérida, Venezuela.  It was a non-experimental and correlational study.  The sample included 189 students (27% male and 73% female) with an average age of 19.58 ± 1.57 (men: 19.81 years of age ± 1.74 and women: 20.24 years of age ± 1.76).  Participants were intentionally selected from first-year courses of the Medicine, Nursing and Nutrition programs.  The Body Shape Questionnaire (BSQ) (Cooper and Taylor, 1987) was the instrument used to measure body image dissatisfaction and Graffar’s modified method (Méndez and De Méndez, 1994) was applied to determine the participants’ socioeconomic status.  A descriptive analysis (frequency, percentages, mean) and an inferential analysis (one-way ANOVA) were applied to the data using SPSS (Statistical Package for Social Sciences) version 9.0.  One of the most important findings in this study was the determination of a statistically significant relationship between dissatisfaction and body image and between low self-esteem and gender χ2 (2, N= 189) = 9.686, p=0.008.  Using ANOVA also helped determine that differences in the mean for dissatisfaction and low self-esteem levels with body image and gender are statistically significant, F= 11.236; p=0.008, F=10.23; p=0.002, respectively.  Conclusions: results obtained suggest a relationship between dissatisfaction and low self-esteem due to physical appearance. Consequently, subjects reject their body image because of a distorted or undistorted perception of their physical appearance, which can possibly affect self-esteem.  Moreover, it is observed that the students’ psychological health is more related to their satisfaction with their body-image than to the way their body image is perceived. Consequently, this group of participants must be analyzed regarding their self-esteem due to body image, as an expression in the institutional environment.  It is also important to emphasize that gender may be a risk factor concerning eating disorders.  We believe the foregoing because women showed higher dissatisfaction levels because of their physical appearance being conditioned by a higher dissatisfaction with their perceived body image, which is characterized by an overestimation of the physical dimension of their body image.

Protect your body, your temple : Know the Facts About Arthritis

These bookmarks state: Arthritis is the most common chronic illness and is the leading cause of disability in the U.S. It is a term used to refer to more than 100 different joint diseases. The severity of the diseases range from relatively mild forms such as tendinitis and bursitis to crippling forms such as lupus, rheumatoid arthritis, fibromyalgia and other disorders that affect every part of the body. It affects an estimated 52 million (1 in 5) adults in the U.S. and is expected to affect approximately 67 million by 2030. S.C. has the 6th highest rate of arthritis in the nation. An estimated one million, or 28 percent, of South Carolinians 19 or older report having arthritis.

Cafuza, Mulata, Negra: body and memory in the discourse of brazilian beers

This article aims to undertake a discursive analysis of the label and advertising material of three beers sold in Brazil: the Cafuza beer, the Mulata beer and Devassa Negra beer. Starting from the regularity that binds and weaves the statements in question - the reference to the African-Brazilian woman - the objective is to present an analysis that considers the semiotic nature of these statements, and bring out their enunciation margins and its historical dimension. The purpose is to analyze the discursive thread that provides conditions of emergence, providing visibility to the scenario of enslavement still perdurable here as historical a priori, in a game of memories that echo through time. What we will see is the body of the black woman (also mulatto and black-indian woman) caught by a discourse that comes from the image of the female sexual slavery and reaches today its exacerbation, especially if we think of the (con)fusion established between the brand names of those beers and the women printed on their labels: products to be consumed? As a theoretical and methodological framework, this article will have as a starting point the discussions made within the French Discourse Analysis in the course of the 1980s. We will bring forward a discussion, although in general, on how emerges, in that decade, the concerns about a semiotic materiality of discourse, beyond the linguistic materiality. Anchored by this panorama, our goal is to work out new perspectives through its analytical application. It is the attempt to take the statement considering the different languages that comprise it, as well as to provide it with the historical density intrinsic to it, making it appear, in the light of the day, what was not visible immediately.

High body mass index is not a barrier to physical activity: Analysis of international rugby players' anthropometric data

Recent data indicate that levels of overweight and obesity are increasing at an alarming rate throughout the world. At a population level (and commonly to assess individual health risk), the prevalence of overweight and obesity is calculated using cut-offs of the Body Mass Index (BMI) derived from height and weight. Similarly, the BMI is also used to classify individuals and to provide a notional indication of potential health risk. It is likely that epidemiologic surveys that are reliant on BMI as a measure of adiposity will overestimate the number of individuals in the overweight (and slightly obese) categories. This tendency to misclassify individuals may be more pronounced in athletic populations or groups in which the proportion of more active individuals is higher. This differential is most pronounced in sports where it is advantageous to have a high BMI (but not necessarily high fatness). To illustrate this point we calculated the BMIs of international professional rugby players from the four teams involved in the semi-finals of the 2003 Rugby Union World Cup. According to the World Health Organisation (WHO) cut-offs for BMI, approximately 65% of the players were classified as overweight and approximately 25% as obese. These findings demonstrate that a high BMI is commonplace (and a potentially desirable attribute for sport performance) in professional rugby players. An unanswered question is what proportion of the wider population, classified as overweight (or obese) according to the BMI, is misclassified according to both fatness and health risk? It is evident that being overweight should not be an obstacle to a physically active lifestyle. Similarly, a reliance on BMI alone may misclassify a number of individuals who might otherwise have been automatically considered fat and/or unfit.

Existential experience : the unfolding

This paper reports on a project concerned with the relationship between person and space in the context of achieving a contemplative state. The need for such a study originated with the desire to contribute to the design of multicultural spaces which could be used for a range of activities including prayer and meditation. Given that the words ‘prayer’ and ‘meditation’ are highly value-laden and potentially alienating for some people, it was decided to use the more accessible term ‘contemplative’. While the project is still underway,several findings have emerged that can be reported on and are of relevance to the conference both methodologically and substantively. Informed by phenomenological methodology, data were collected from a diverse group of people using photo-elicitation and interviewing. The technique of photo-elicitation proved to be highly effective in helping people to reveal their everyday lived experience of contemplative spaces. This methodological aspect of the project is described more fully in the paper. The initial stage of analysis produced two categories of data: varying conceptions of contemplation and contemplative space; and, common understandings of contemplation and contemplative space. From this it was found that achieving a state of contemplation involves both the person and the environment in a dialectic process of unfolding. The unfolding has various physical, psycho-social, and existential dimensions or qualities which operate sequentially and simultaneously. In the paper, these are labelled:the unfolding of the core; distinction; manifestation; cleansing; creation; and sharing, and have parallels with Mircea Eliade’s 1959 definition of sacred as 'something that manifests itself, shows itself, as something wholly different from the profane’. It also connects with the views of Nishida Kitaro from the Kyoto School of Philosophy on the theme of ‘absolute nothingness’: ‘the body-mind is dropped off and we are united with the consciousness of absolute nothingness’ (Kitaro in Heisig, 2001, p. 169). According to Marion (2005), ‘nothingness’ is defined by givenness. In the paper, this fold of givenness is interpreted in the context of the qualities of the environment that accomplish the act of coming forward into visibility through the dialectic relationship with a person.

Increased body temperature following subarachnoid haemorrhage : a retrospective correlational study

Introduction: Nursing clinicians are primarily responsible for the monitoring and treatment of increased body temperature. The body temperature of patients during their acute care hospital stay is measured at regular repeated intervals. In the event a patient is assessed with an elevated temperature, a multitude of decisions are required. The action of instigating temperature reducing strategies is based upon the assumption that elevated temperature is harmful and that the strategy employed will have some beneficial effect. Background and Significance: The potential harmful effects of increased body temperature (fever, hyperthermia) following neurological insult are well recognised. Although few studies have investigated this phenomenon in the diagnostic population of non-traumatic subarachnoid haemorrhage, it has been demonstrated that increased body temperature occurs in 41 to 72% of patients with poor clinical outcome. However, in the Australian context the frequency, or other characteristics of increased body temperature, as well as the association between increased body temperature with poor clinical outcome has not been established. Design: This study used a correlational study design to: describe the frequency, duration and timing of increased body temperature; determine the association between increased body temperature and clinical outcome; and describe the clinical interventions used to manage increased body temperature in patients with non-traumatic subarachnoid haemorrhage. A retrospective clinical chart audit was conducted on 43 patients who met the inclusion criteria. Findings: The major findings of this study were: increased body temperature occurred frequently; persisted for a long time; and onset did not occur until 20 hours after primary insult; increased body temperature was associated with death or dependent outcome; and no intervention was recorded in many instances. Conclusion: This study has quantified in a non-traumatic subarachnoid haemorrhage patient population the characteristics of increased body temperature, established an association between increased body temperature with death or dependent outcome and described the current management of elevated temperatures in the Australian context to improve nursing practice, education and research.
