A naturalistic investigation of former Olympic cyclists' cognitive strategies for coping with exertion pain during performance

In endurance sports, there is one element that all athletes who wish to excel must confront.exertion pain. The purpose of this study was to describe and explain the nature and effects of the cognitive strategies former Olympic cyclists used to cope with exertion pain during performance. Nine participants were asked to describe exertion pain and how they managed it. Two hundred twenty-two quotes formed the basis for the analysis. The quotes were coalesced to six higher-order themes. The following conclusions were extracted from the themes: (I) the degree of pain was purely a perception, (2) pain varied depending upon the satisfaction the athlete received from the experience when ail physiological variables were held constant, (3) cognitive skills such as goal setting, imagery, and positive self-talk were routinely used, (4) the mind and body were viewed as a dualism when performing, (5) pain was a positive experience and part of sport and an individual's identity, and (6) riding in a position of control tended to lessen the perception of pain. The results revealed that former Olympic cyclists used a myriad of cognitive strategies to cope with endurance pain while training and competing and that all of them attended to the pain rather than attempting to ignore it.
FOLFOX and FLOX Regimens for the Adjuvant Treatment of Resected Stage II and III Colon Cancer

The MOSAIC trial showed that the use of adjuvant oxaliplatin and an infusional regimen of 5-FU/LV in the treatment of stage II/III colon cancer improved disease-free survival (DFS). The NSABP's C-07 trial evaluated the addition of oxaliplatin to a weekly Roswell Park regimen of bolus 5-FU/LV and found a similar improvement in DFS. The benefit of oxaliplatin appears to be independent of the 5-FU/LV regimen used. This paper reviews the efficacy and toxicities of these two regimens and is meant to serve as a guide for clinical practice.
Effects of energy drinks on the cardiovascular system

Throughout the last decade, the use of energy drinks has been increasingly looked upon with caution as potentially dangerous due to their perceived strong concentration of caffeine aside from other substances such as taurine, guarana, and L-carnitine that are largely unknown to the general public. In addition, a large number of energy drink intoxications have been reported all over the world including cases of seizures and arrhythmias. In this paper, we focus on the effect of energy drinks on the cardiovascular system and whether the current ongoing call for the products’ sales and regulation of their contents should continue.
Effect of polyaspartic acid on pharmacokinetics of gentamicin after single intravenous dose in the dog

The effects of poly-L-aspartic acid on the pharmacokinetics of gentamicin were examined by using a randomized crossover trial design with the dog. When analyzed according to a three-compartment open model, poly-L-aspartic acid reduced some first-order rate equation constants (A3, lambda 1, and lambda 3), the deep peripheral compartment exit microconstant (k31), the elimination rate constant (k(el)), and the area under the concentration-time curve from 0 to 480 h (AUC0-480) (0.21-, 0.60-, 0.26-, 0.27-, 0.72-, and 0.76-fold, respectively; P < 0.05) but increased the volume of distribution at steady state (Vss), the volume of distribution calculated by the area method (V(area)), the apparent volume of the peripheral compartment (Vp), and all mean time parameters. These results suggested that poly-L-aspartic acid increased the distribution of gentamicin to or binding within the deep peripheral compartment and that poly-L-aspartic acid may have delayed gentamicin transit through the peripheral tissues. In contrast, poly-L-aspartic acid did not alter pharmacokinetic parameters relevant to the central or shallow peripheral compartments to a clinically significant extent. Although gentamicin's pharmacokinetic parameters of relevance to therapeutic drug monitoring were not directly altered, this study has provided pharmacokinetic evidence that poly-L-aspartic acid alters the peripheral distribution of gentamicin. This pharmacokinetic interaction occurred after a single intravenous dose of each drug. Therefore, this interaction should be investigated further, before polyaspartic acid can be considered for use as a clinical nephroprotectant.
The Tasmanian Devil Transcriptome Reveals Schwann Cell Origins of a Clonally Transmissible Cancer

Be-Deviled Cancer Recently, a deadly transmissible cancer has emerged in Tasmanian devils, the largest existing marsupial carnivore. This disease, devil facial tumor disease (DFTD), leads to the growth of large facial tumors that frequently metastasize to internal organs. DFTD is thought to be transmitted by biting, and leads to death of affected animals within months, usually by obstructing the animals' ability to feed. Consequently, in the last 10 years Tasmanian devil numbers have dropped by about 60%. There are no genetic tests, vaccines, or treatments available for this disease, and without intervention, models predict that DFTD could cause extinction of Tasmanian devils in the wild within 50 years. Several lines of evidence suggest that DFTD is transmitted as a clonal allograft, whereby the cancer cells themselves are the agents of tumor transmission. Murchison et al. (p. 84) examined this hypothesis in detail by genotyping 25 tumor-host pairs from around Tasmania at 14 microsatellite loci and at a variable mitochondrial polymorphism. DFTD tumors were indeed found to be genetically distinct from their hosts and almost completely genetically identical to one another, supporting the idea of transmission by allograft. Sequencing the Tasmanian devil facial tumor disease provides a potential diagnostic marker. The Tasmanian devil, a marsupial carnivore, is endangered because of the emergence of a transmissible cancer known as devil facial tumor disease (DFTD). This fatal cancer is clonally derived and is an allograft transmitted between devils by biting. We performed a large-scale genetic analysis of DFTD with microsatellite genotyping, a mitochondrial genome analysis, and deep sequencing of the DFTD transcriptome and microRNAs. These studies confirm that DFTD is a monophyletic clonally transmissible tumor and suggest that the disease is of Schwann cell origin. On the basis of these results, we have generated a diagnostic marker for DFTD and identify a suite of genes relevant to DFTD pathology and transmission. We provide a genomic data set for the Tasmanian devil that is applicable to cancer diagnosis, disease evolution, and conservation biology.
Eulerian video magnification for revealing subtle changes in the world

Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames. The resulting signal is then amplified to reveal hidden information. Using our method, we are able to visualize the flow of blood as it fills the face and also to amplify and reveal small motions. Our technique can run in real time to show phenomena occurring at the temporal frequencies selected by the user.
Hyperglycemia Correlates with Outcomes in Patients Receiving Total Parenteral Nutrition

Background:Hyperglycemia is associated with higher mortality rates after myocardial infarction, stroke, and in critically ill patients. This study was made to determine the associations between hyperglycemia and adverse outcomes in patients receiving total parenteral nutrition (TPN). Methods:A retrospective cohort study included total 457 patients (age, 66.4 ± 16.3 years) receiving TPN in 2004. The patients were divided by mean glucose level into quartiles: quartile 1 (<114 mg/dL, Q1), quartile 2 (114 to 137 mg/dL, Q2), quartile 3 (137 to 180 mg/dL, Q3), and quartile 4 (>180 mg/dL, Q4). A logistic regression analysis was performed to determine whether the degree of hyperglycemia was associated with the adverse outcomes. Results:The odds ratio of death was significantly increased in quartile 2 (OR, 2.1 [95% CI: 1.1 to 4.0]) (P = 0.02), quartile 3 (OR, 2.3 [95% CI: 1.2 to 4.5]) (P = 0.01), and quartile 4 (OR, 5.0 [95% CI: 2.4 to 10.6]) (P < 0.01) as compared with quartile 1. Each 10-mg/dL increase in mean blood glucose level was associated with an increased risk factor of infection (OR, 1.09 [95% CI: 1.05 to 1.13]) (P < 0.01), cardiac complications (OR, 1.10 [95% CI: 1.03 to 1.17]) (P < 0.01), acute renal failure (OR, 1.07 [95% CI: 1.03 to 1.11]) (P < 0.01), and respiratory failure (OR, 1.08 [95% CI: 1.02 to 1.14]) (P < 0.01). The risk of adverse outcomes increased with hyperglycemia, independent of age, sex, body weight, prior diagnosis of diabetes, ICU stay, insulin therapy, blood sugar readings before TPN treatment, and frequency of blood sugar measurements. Conclusions:Hyperglycemia in patients receiving TPN correlates with morbidities and mortality. A prospective, randomized, controlled study instituting aggressive hyperglycemic control is required to determine whether the control of blood glucose can improve outcomes in patients receiving TPN.
Theta-Bearing and Complement-Receptor Lymphocytes Are Distinct Populations of Cells

In the mouse, most (or all) complement-receptor lymphocytes and theta-bearing lymphocytes are part of nonoverlapping populations of cells. This finding validates the use of these membrane markers to characterize populations of lymphocytes. In addition, it is probable that, although receptors for complement and membrane-bound immunoglobulins coexist on the same lymphoid cells, these markers are located at separate sites on the membrane.
Sexual and Reproductive Health Disparities in a National Sample of Hispanic and Non-Hispanic White U.S. College Students

Hispanic students are the fastest growing minority population on U.S. college campuses. The purpose of this study was to examine differences in the sexual and reproductive health behaviors and outcomes between Hispanic and nonHispanic White college students. Analyses utilized data from 15,518 nonmarried undergraduates (aged 18-24 years) responding to the Fall 2009 American College Health Association-National College Health Assessment II, a national sample of U.S. college students. Binary logistic regression analyses were used to examine disparities in sexual and reproductive health behaviors and outcomes, including sexual behavior, contraceptive and condom use, HIV testing, and STD and unintended pregnancy history, between Hispanic and non-Hispanic Whites. Hispanics had greater odds of reporting a past-year STD, although rates of reported sexual risk behaviors were no higher among Hispanics compared with non-Hispanic Whites. Compared to non-Hispanic Whites, fewer Hispanics reported using birth control pills. Hispanics were 2.5 times less likely to report using any method to prevent pregnancy, which may explain why Hispanics were more likely to report emergency contraceptive use in the past 12 months and a past-year unintended pregnancy. Important sexual health disparities exist among U.S. students, which have important
Ethnic Diversity within Australian Homes: Has Television Caught up to Social Reality?

Inter-ethnic intimacy is on the rise in Australia, bringing an unprecedented level of ethnic diversity into our homes. Yet analyses of media representations of ethnic diversity have concentrated on the community level, neglecting the intimate sphere of family life. This paper explores the possibilities and limits of love within and across ethnic boundaries on fictional Australian television programmes. The results of a nine-week content analysis reveal a mixed picture. Inter-ethnic intimacy was regularly portrayed; but committed, long-term relationships across ethnic boundaries (marriage and co-habitation) were scarce. And although Australian television producers did not shy away from portraying physical intimacy across ethnic boundaries, emotional intimacy was often absent. Overt stereotyping of ethnic minority characters involved in inter-ethnic relationships was rare – instead, ethnic differences were downplayed or erased. Storylines were underpinned by the assimilation of inter-ethnic couples – in all their diversity – into the (white) mainstream.
Long-term alterations of colonic nerve–mast cell interactions induced by neonatal maternal deprivation in rats

Background: Neonatal maternal deprivation induces colonic alterations in adult rats, such as hypersensitivity to distension or an increase in paracellular permeability, characteristics of irritable bowel syndrome (IBS) patients. Recent studies described neuroimmune alterations in the colonic mucosa of IBS patients. Methods: Male Wistar rats were submitted to maternal deprivation for 3 h daily during postnatal days 2–14, and were sacrificed at 4 or 12 weeks of age. Control pups were left undisturbed with their dam. Results: Colonic mast cell hyperplasia was observed at 4 and 12 weeks in maternally deprived rats, and was associated with an increase in protease content. Mucosal nerve fibre density assessed by protein gene product (PGP) 9.5 immunoreactivity was increased at 12 weeks but not at 4 weeks, while calcitonin gene-related protein (CGRP)-immunoreactive fibres remain constant. Synaptogenesis assessed by synaptophysin immunostaining was increased at 4 weeks but not at 12 weeks. The number of mast cells in close proximity to PGP 9.5- or CGRP-immunoreactive fibres was greater at both 4 and 12 weeks. Expression of neurokinin NK1 receptors in the spinal cord was enhanced at 12 weeks. No significant change in total mast cell number, PGP 9.5 immunoreactivity and mast cells associated with PGP 9.5-immunoreactive fibres was observed in the jejunum. Treatment of pups with anti-nerve growth factor (NGF) antibodies abolished the increases in synaptogenesis and in the number of mast cells in close proximity to nerve fibres observed 4 weeks after maternal deprivation. Conclusions: Neonatal maternal deprivation induces closer association of colonic mast cells with nerves, which is similar to that seen in IBS patients. NGF is a possible mediator of this effect.
The future of hydrology: An evolving science for a changing world

Human activities exert global‐scale impacts on our environment with significant implications for freshwater‐driven services and hazards for humans and nature. Our approach to the science of hydrology needs to significantly change so that we can understand and predict these implications. Such an adjustment is a necessary prerequisite for the development of sustainable water resource management strategies and to achieve long‐term water security for people and the environment. Hydrology requires a paradigm shift in which predictions of system behavior that are beyond the range of previously observed variability or that result from significant alterations of physical (structural) system characteristics become the new norm. To achieve this shift, hydrologists must become both synthesists, observing and analyzing the system as a holistic entity, and analysts, understanding the functioning of individual system components, while operating firmly within a well‐designed hypothesis testing framework. Cross‐disciplinary integration must become a primary characteristic of hydrologic research, catalyzing new research and nurturing new educational models. The test of our quantitative understanding across atmosphere, hydrosphere, lithosphere, biosphere, and anthroposphere will necessarily lie in new approaches to benchmark our ability to predict the regional hydrologic and connected implications of environmental change. To address these challenges and to serve as a catalyst to bring about the necessary changes to hydrologic science, we call for a long‐term initiative to address the regional implications of environmental change.
Effect of gelatinisation of starch with casein proteins on incretin hormones and glucose transporters in vitro

Foods that have a low glycaemic index or foods that contain slowly digestible starch are beneficial in controlling fluctuations in blood glucose and insulin levels. The study hypothesis is that gelatinisation of starch in structured casein networks provides a method for decreasing the digestion rate of the starch and, hence, minimising postprandial glucose fluctuations. This study examined the effect of starch gelatinisation with or without casein on (1) gene expression and peptide secretion levels of the incretin hormones glucagon-like peptide 1 and glucose-independent insulinotropic polypeptide and (2) gene expression of the sodium–glucose cotransporter and GLUT-2 in intestinal cell culture systems. The intestinal epithelial cell line, STC-1, and the enteroendocrine colonic cell line, Caco-2, were exposed to in vitro digested foods (starch gelatinised with α-casein, starch gelatinised with β-casein and gelatinised starch alone). The encapsulation of starch with casein before in vitro digestion lowers levels of incretin hormone secretion. Digestion of starch gelatinised with casein also releases less glucose than starch alone as indicated by significantly (P < 0·05) lower levels of glucose transporter mRNA transcripts. Some subtle cellular response differences were observed following exposure to starch gelatinised with α- compared to β-casein. Fractionation of α-casein and β-casein by reverse-phase HPLC identified that fractions that differed in hydrophobicity differed significantly (P < 0·05) in their ability to promote secretion of the incretin hormones. Evidence suggests that gelatinisation of starch with casein may be a functional food ingredient that minimises blood glucose fluctuations.
Inter-individual Relationships between Sympathetic Arterial Baroreflex Function and Cerebral Perfusion Control in Healthy Males

Maintenance of adequate cerebral perfusion during normal physiological challenges requires integration between cerebral blood flow (CBF) and systemic blood pressure control mechanisms. Previous studies have shown that cardiac baroreflex sensitivity (BRS) is inversely related to some measures of cerebral autoregulation. However, interactions between the sympathetic arterial baroreflex and cerebral perfusion control mechanisms have not been explored. To determine the nature and magnitude of these interactions we measured R–R interval, blood pressure, CBF velocity, and muscle sympathetic nerve activity (MSNA) in 11 healthy young males. Sympathetic BRS was estimated using modified Oxford method as the relationship between beat-to-beat diastolic blood pressure (DBP) and MSNA. Integrated control of CBF was quantified using transfer function analysis (TFA) metrics derived during rest and Tieck's autoregulatory index following bilateral thigh cuff deflation. Sympathetic BRS during modified Oxford trials was significantly related to autoregulatory index (r = 0.64, p = 0.03). Sympathetic BRS during spontaneous baseline was significantly related to transfer function gain (r = −0.74, p = 0.01). A more negative value for sympathetic BRS indicates more effective arterial baroreflex regulation, and a lower transfer function gain reflects greater cerebral autoregulation. Therefore, these findings indicate that males with attenuated CBF regulation have greater sympathetic BRS (and vice versa), consistent with compensatory interactions between blood pressure and cerebral perfusion control mechanisms.
Qualification methodology for sub-micron ICs at the Low Noise Underground Laboratory of Rustrel

The chosen methodology associates the use of real time testing in altitude and underground environments. Experiments are performed on Xilinx FPGAs. Goals, experiment design, statistical confidence, initial results are analyzed and discussed.
Casposon integration shows strong target site preference and recapitulates protospacer integration by CRISPR-Cas systems

Casposons are a recently discovered group of large DNA transposons present in diverse bacterial and archaeal genomes. For integration into the host chromosome, casposons employ an endonuclease that is homologous to the Cas1 protein involved in protospacer integration by the CRISPR-Cas adaptive immune system. Here we describe the site-preference of integration by the Cas1 integrase (casposase) encoded by the casposon of the archaeon Aciduliprofundum boonei. Oligonucleotide duplexes derived from the terminal inverted repeats (TIR) of the A. boonei casposon as well as mini-casposons flanked by the TIR inserted preferentially at a site reconstituting the original A. boonei target site. As in the A. boonei genome, the insertion was accompanied by a 15-bp direct target site duplication (TSD). The minimal functional target consisted of the 15-bp TSD segment and the adjacent 18-bp sequence which comprises the 3′ end of the tRNA-Pro gene corresponding to the TΨC loop. The functional casposase target site bears clear resemblance to the leader sequence-repeat junction which is the target for protospacer integration catalyzed by the Cas1–Cas2 adaptation module of CRISPR-Cas. These findings reinforce the mechanistic similarities and evolutionary connection between the casposons and the adaptation module of the prokaryotic adaptive immunity systems.
Neural Correlates of Forward Planning in a Spatial Decision Task in Humans

Although reinforcement learning (RL) theories have been influential in characterizing the mechanisms for reward-guided choice in the brain, the predominant temporal difference (TD) algorithm cannot explain many flexible or goal-directed actions that have been demonstrated behaviorally. We investigate such actions by contrasting an RL algorithm that is model based, in that it relies on learning a map or model of the task and planning within it, to traditional model-free TD learning. To distinguish these approaches in humans, we used functional magnetic resonance imaging in a continuous spatial navigation task, in which frequent changes to the layout of the maze forced subjects continually to relearn their favored routes, thereby exposing the RL mechanisms used. We sought evidence for the neural substrates of such mechanisms by comparing choice behavior and blood oxygen level-dependent (BOLD) signals to decision variables extracted from simulations of either algorithm. Both choices and value-related BOLD signals in striatum, although most often associated with TD learning, were better explained by the model-based theory. Furthermore, predecessor quantities for the model-based value computation were correlated with BOLD signals in the medial temporal lobe and frontal cortex. These results point to a significant extension of both the computational and anatomical substrates for RL in the brain.
