Soccer is a high-level skill sport that requires aerobic and anaerobic strength, as well as physical skills related to speed, agility, strength, and power. To meet these physical needs of soccer players, coaches now offer a variety of aerobic exercises that essentially use the lower and upper extremities, as well as large muscle groups. Correct technical performance of exercises protects not only from various injuries but also saves unnecessary energy consumption. For this reason, the purpose of this research is to critically analyze research that has examined the importance of aerobic endurance in young soccer players. The following databases were searched: Pub Med, Scopus, Google Scholar, CrossRef, etc. to find all relevant publications. The following keywords were used in this search: "soccer", "young soccer players", "VO2 max", and "soccer performance", along with adjectives such as "effect", "change" and "impact". It was found that the aerobic demands of soccer players are crucial and strategic for the game.

Interpenetrating polymer network of blocked polyurethane and phenolic resin. II. Kinetic formation, swelling ratio, thermal properties, and flame retardance
Authors: Chen Chin‐Hsing 
Published: May 2011

AbstractBlocked polyurethane (BPU)/phenolic (PF) interpenetrating polymer network (IPN) were prepared from BPU prepolymer with m‐xylylenediamine (MXDA) as a chain extender and PF prepolymer using p‐toluene sulfonic acid (PTSA) as a catalyst. The kinetic aspects of the formation of a second network in the presence of the first have been studied in BPU/PF IPN. The effect on kinetics of parameters such as the BPU content and the reaction temperature has been examined. The studies of swelling ratio, thermal properties, and flame retardance of IPN are based on BPU content and filler content. Results showed that the swelling ratio of IPN increased with the increasing of BPU content, and decreased with the increasing of filler (kaolin) content. The IPN possesses good thermal properties of weight loss and thermal degraded temperature by thermogravimetric analysis (TGA) test when the IPN decreased the BPU content and increased the filler (kaolin) content. The IPN showed the excellent flame retardance when the IPN decreased the BPU content. POLYM. ENG. SCI., 2011. © 2011 Society of Plastics Engineers

Published: May 2011

AbstractA novel semi‐interpenetrating polymer networks (semi‐IPNs) porous salt‐resistant superabsorbent composite was prepared by copolymerization of partially neutralized acrylic acid and acrylamide using polyethylene glycol as semi‐IPNs composite, N,N′‐methylenebisacrylamide, triene propanol phosphate, and trihydroxymethyl propane glycidol ether as crosslinking agents, methanol, propanol, and butanol as foaming agents, and L‐ascorbic acid and peroxide hydrogen as initiators. To improve the properties of swollen hydrogel, such as strength, resilience, permeabilities, and dispersion, the copolymer was surface‐crosslinked, and then blended with aluminum sulfate, sodium carbonate, and sodium 1‐octadecanol phosphate in the course of post treatment. The influences of reaction conditions on properties of superabsorbent composite were investigated and optimized, and the water absorbency of superabsorbent composite prepared at optimal conditions in 0.9 wt% NaCl aqueous solution under atmospheric pressure and certain load (P ≈ 2 × 103 Pa) were 61 g g−1 and 16.7 g g−1, respectively. Moreover, the swelling rate reached 22.003 × 10−3 g (g s)−1. And the excellent hydrogel properties, such as hydrogel strength, resilience, permeabilities, and dispersion were also obtained. POLYM.

AbstractCurrent treatments of neuropathic pain arising from conditions such as nerve injury/compression are only partially effective, and limited in their use by side‐effects. p38 mitogen‐activated protein kinase (MAPK) is involved in the regulation and synthesis of inflammatory mediators, and is the target for a novel class of cytokine‐suppressive anti‐inflammatory drugs. p38 inhibitors may reduce neuronal sensitisation in preclinical models of neuropathic pain, particularly where there is a substantial inflammatory component. An exploratory, multicentre, double‐blind, placebo‐controlled, two‐period, cross‐over trial was undertaken to evaluate the effect of dilmapimod (SB‐681323), a selective p38 MAPK inhibitor, on neuropathic pain symptoms and signs. Fifty patients with nerve trauma, radiculopathy or carpal tunnel syndrome were randomised; 43 patients completed the study. Eligible patients received oral dilmapimod and placebo twice daily for 2 weeks, with an intervening washout period of 2–4 weeks. Subjects attended weekly for efficacy and safety assessments, which included evaluation of daily and current pain intensity using an 11‐point numerical rating scale (NRS), quantitative sensory testing, allodynia and global impression of change. There was a statistically significant reduction in the primary endpoint of average daily pain score during the second week of treatment among patients treated with dilmapimod (15 mg/day) compared to placebo using NRS [0.80; 95% CI (0.28, 1.33); p = 0.0034]. A similar trend for effect was seen in some secondary endpoints. Dilmapimod was well tolerated, with no clinically relevant safety findings. p38 MAPK inhibitors merit further evaluation for neuropathic pain in larger clinical trials, particularly for clinically meaningful analgesic effect size.
Social comparison performance standards, threat, and tolerance for experimentally‐induced pain
Authors: Jackson Todd , Phillips Heath 
Published: May 2011

AbstractSocial modelling experiments have illustrated how upward social comparisons (i.e., observing pain tolerant role models) can facilitate tolerance relative to downward social comparison (i.e., observing pain intolerant alternatives). However, because clinical studies suggest that people prefer to make downward social comparisons with less fortunate others when they are threatened or overwhelmed with pain or illness, it seems plausible that upward social comparisons confer fewer benefits when pain is appraised as threatening. To address this issue, we assessed effects of verbally‐presented upward and downward social comparison standards on tolerance for cold pressor pain among 124 Australian adults (44 men, 80 women) primed with either more or less threatening orienting information about task‐related pain sensations. As predicted, participants exposed to the lower threat orienting prime and upward comparison performance standard were significantly more pain tolerant than peers in all other conditions. Conversely, the average tolerance time for participants presented with the higher threat orienting prime and upward comparison standard did not differ from that of either downward comparison group. The research highlighted powerful situational influences on tolerance for experimental pain and identified conditions under which verbally‐presented upward social comparison standards may facilitate and hinder the capacity to bear pain.

Published: May 2011

AbstractBackgroundThe communication between clinician and patient is the basis of psychiatric treatment. However, there has been little practical attention to training in it, and no specific theory of what constitutes good communication in psychiatry has been developed. This review aims to identify principles that guide good communication.MethodsA conceptual review of guiding principles for how clinicians should communicate with patients to achieve clinical objectives in psychiatry.ResultsFive guiding principles for clinicians were identified: a focus on the patient's concerns; positive regard and personal respect; appropriate involvement of patients in decision making; genuineness with a personal touch; and the use of a psychological treatment model.ConclusionsThe principles are mostly generic, but their implementation can be particularly challenging in psychiatry. They may guide further empirical research on effective communication in psychiatry and be utilised using different personal skills of clinicians.
Effects of altered glucose supply and adiposity on expression of hypothalamic energy balance regulatory genes in late gestation growth restricted ovine fetuses

AbstractIntra‐uterine growth restriction (IUGR) predisposes obesity in adulthood. This may be due to altered fetal nutrition causing sustained changes within the developing hypothalamic energy balance regulatory system. Using our established ovine model of IUGR, 130‐day singleton fetuses (term = 147 days) were obtained from growing adolescent mothers on control dietary intake (C), high intake (H) or H with growth hormone administration during either early (H + early GH) or late gestation (H + late GH) (n = 6/group). GH increased maternal glycemia for the duration of treatment. H and H + early GH fetuses showed IUGR compared with C fetuses; body weight was partially restored in H + late GH fetuses, with 40% increased adiposity. In the fetal hypothalamic arcuate nucleus (ARC), cocaine‐ and amphetamine‐regulated transcript mRNA (anorexigenic) was decreased in H fetuses and correlated across all groups with total fetal liver glycogen. Neuropeptide Y, agouti‐related peptide (orexigenic) and proopiomelanocortin (anorexigenic) mRNAs were not different between groups. Insulin receptor mRNA in the ARC was increased in H, H + early GH and H + late GH fetuses and correlated negatively with fetal plasma insulin. Leptin receptor mRNA in the ARC correlated positively with fetal plasma leptin concentration and fetal fat content. Therefore, in IUGR fetuses, a key anorexigenic neuropeptide is sensitive to altered glucose supply and the hypothalamic leptin‐signaling pathway is altered prenatally by increased adiposity and leptinemia. These changes could impact on postnatal energy balance regulation.

AbstractObjectiveTo achieve Millennium Development Goals 4 and 5 in Nigeria, a quality assurance project in obstetrics in 10 hospitals in northern Nigeria was established to improve maternal and fetal outcome.MethodsThe project commenced in January 2008 with assessment and improvement of the structure of the 10 hospitals. Continuous maternal and fetal data collection and analysis were conducted from 2008 to 2009 by means of a maternity record book and structured monthly summary form. The quality of hospital infrastructure and equipment was also assessed.ResultsThe mean maternal mortality ratio (MMR) was reduced from 1790 per 100 000 births in the first half of 2008 to 940 per 100 000 births in the second half of 2009. The average fetal mortality ratio (FMR) decreased slightly from 84.9 to 83.5 per 1000 births. There was an inversely proportional relationship between the total number of deliveries in a hospital and MMR and FMR. There was a close correlation between the MMR and the equipment status and hygiene conditions of the hospitals.ConclusionContinuous monitoring of quality assurance in maternity units raised the awareness of the quality of obstetric performance and improved the quality of care provided, thereby improving MMR.

Published: May 2011

The increasing interest in studying the interactions between cells and the extracellular matrix (ECM) has created a need for high throughput low-cost three-dimensional (3D) culture systems. The recent development of tubeless microfluidics via passive pumping provides a high throughput microchannel culture platform compatible with existing high throughput infrastructures (e.g., automated liquid handlers). Here, we build on a previously reported high throughput two-dimensional system to create a robust automated system for 3D culture. Operational controls including temperature and sample handling have been characterized and automated. Human mammary fibroblasts (HMFs) suspended in type I collagen are loaded and cultured in microchannel arrays and used to optimize the system operational parameters. A Peltier cooler maintains the collagen as a liquid at 4 °C during cell seeding, followed by polymerization at 37 °C. Optimization of this platform is discussed (e.g., controlling collagen contraction, increasing cell viability, preventing the removal of microchannel contents), and 3D distribution of HMFs is examined by fluorescent microscopy. Finally, we validate the platform by automating a previously developed 3D breast carcinoma coculture assay. The platform allows more efficient 3D culture experiments and lays the foundation for high throughput studies of cell—ECM interactions.
Can including pros and cons increase the helpfulness and persuasiveness of online reviews? The interactive effects of ratings and arguments
Authors: Schlosser Ann E. 
Published: May 2011

AbstractOne guideline given to online reviewers is to acknowledge a product's pros and cons. Yet, I argue that presenting two sides is not always more helpful and can even be less persuasive than presenting one side. Specifically, the effects of two‐ versus one‐sided arguments depend on the perceived consistency between a reviewer's arguments and rating. Across a content analysis and three experiments that vary the information provided in the online review and whether the ratings are positive or negative, the results support these predictions. Furthermore, beliefs that the reviewer is able (vs. willing) to tell the truth mediated the effects.
The course of motivation
Authors: Touré‐Tillery Maferima , Fishbach Ayelet 
Published: May 2011

AbstractThis article explores the course of motivation in pursuing various goals. We distinguish between two dimensions of motivation: the motivation to attain a focal goal (outcome‐focused dimension) and the motivation to “do things right” in the process of reaching that goal (means‐focused dimension). We identify the conditions under which the motivation to reach a focal goal increases versus decreases over the course of goal pursuit. We then propose that the motivation to “do things right” follows a u‐shaped pattern, such that it is higher at the beginning and end of goal pursuit than in the middle.
Late Quaternary chronology of major dune ridge development in the northeast Rub' al-Khali, United Arab Emirates

Published: May 2011

AbstractThe northeastern sector of the Rub' al-Khali desert in the eastern United Arab Emirates (UAE) is dominated by large NE–SW trending dune ridges orientated perpendicular to the currently prevailing northwesterly wind regime. In this study, extensive use has been made of artificially exposed sections through these major dune ridges that reveal internal sedimentary structures and allow an intensive, high-resolution sampling programme to be carried out. Here, we present the optical dating results for samples from 7 sections. The results indicate that dune activity and preservation occurred within the periods 7–3 ka, 16–10 ka and 22–20 ka with evidence of earlier preservation during marine oxygen isotope stages MIS 3 and 5, with net accumulation rates in the range 2.2–25 m.ka− 1. In several instances, hiatuses in the preserved record of dune accumulation coincide with stratigraphic bounding surfaces visible in the exposed section profiles with associated truncation of internal sedimentary structures. Caution must be exercised when interpreting such gaps in the recorded accumulation chronologies of these dunes since these may simply constitute phases of low preservation potential rather than phases of low aeolian activity. Other factors such as sediment supply and availability in relation to sea-level dynamics may be significant and are also considered.

AimsLoop diuretics are essential for the treatment of chronic heart failure (CHF) but short‐acting diuretics are reported to induce sympathetic nervous system (SNS) activation. This study was performed to compare therapeutic effects of two loop diuretics, long‐acting azosemide and short‐acting furosemide, using 123I‐metaiodobenzylguanidine (123I‐MIBG) scintigraphy.Methods and resultsTwenty‐two patients with New York Heart Association class II–III heart failure and left ventricular dysfunction, who required treatment with a loop diuretic, were included. In this crossover study, 11 patients were randomized to azosemide treatment first and the remaining 11 patients to furosemide. Treatments were administered for 6 months and then patients were crossed over to the second treatment. 123I‐MIBG scintigraphy was performed before and 6 months after the start of treatment with each loop diuretic. Early and delayed images were obtained 20 min and 4 h after administration of 123I‐MIBG, respectively; and the heart/mediastinum (H/M) ratio and washout rate (WR) were measured. In addition, left ventricular ejection fraction (LVEF), levels of brain natriuretic peptide (BNP), and norepinephrine were measured before and 6 months after the start of treatment. No differences were observed between the two groups in terms of concomitant medication, cause of heart failure, H/M ratio, WR, BNP, norepinephrine, or LVEF. The azosemide group exhibited a significant increase in delayed image H/M ratio, and a significant decrease in WR and norepinephrine after the final administration compared with the furosemide group.ConclusionThis study indicates that azosemide suppresses SNS activation compared with furosemide in patients with CHF, suggesting that long‐acting loop diuretics may have more beneficial effects on the prognosis of CHF.
