AbstractMonitoring of therapeutic response in mucopolysaccharidosis (MPS) patients is problematic as most biomarkers are specific for either disease complications or specific organ system involvement. Recent studies have indicated that serum heparin‐cofactor II‐thrombin complex (HCII‐T) may serve as an important biomarker in the group of MPSs where dermatan sulphate is stored. This complex forms when blood coagulates in the presence of glycosaminoglycans (GAGs) where the ultimate amount of HCII‐T that forms reflects the concentration of circulating GAGs. We have studied serum HCII‐T levels in 9 MPS I and 11 MPS II treated patients and have compared values to studies of urinary GAGs. In severe MPS I patients treated with either transplantation or enzyme replacement therapy (ERT), serum HCII‐T levels never reach the range of normal despite normalization of uGAGs in some patients. Some attenuated MPS I patients have normalization of HCII‐T but require a protracted exposure time relative to the drop in urinary GAGs. Treated MPS II patients show a clear correlation of serum HCII‐T levels with the presence of antibodies to Idursulfase, with antibody positive patients showing an early drop in HCII‐T levels with eventual increases in levels often to levels above those seen at baseline. This is contrasted by a robust and persistent drop in uGAGs. Antibody negative MPS II patients show a drop in HCII‐T levels on treatment but levels never normalize despite normalization of uGAGs. This study highlights the utility and biologic relevance of serum HCII‐T levels in monitoring therapy in these disorders.
Self‐thinning lines of organs and aboveground parts based on allometric relationships in overcrowdedPinus densiflorastands
Authors: Xue Li , Hagihara Akio 
Published: July 2011

AbstractThe allometric relationships of mean tree heightand of organ mass densityto mean organ masswere studied in self‐thinningPinus densifloraSieb. et Zucc. stands. Tree height increased significantly with increasing mean mass of organs and aboveground parts on log–log coordinates. The value of the allometric constant θ ranged from 0.2878 to 0.3349. On the other hand, the constant value δ was not significantly different from zero, except for leaves. The value of the allometric constant δ ranged from −0.2926 to 0.0120. According to Weller's allometric model, the slope of the self‐thinning line was calculated from the allometric constantsθandδ. The thinning slope was estimated to be −1.51 in stem, −1.39 in branches, −1.00 in leaf and −1.41 in aboveground parts, respectively. Mass density was high in stem, medium in branches and low in leaves. Mean leaf mass density decreased significantly with decreasing stand density on log–log coordinates, which could be interpreted as indicating the importance of the constant final leaf biomass in overcrowdedP. densiflorastands. The self‐thinning exponents of branch, stem and aboveground parts were not significantly different from 3/2, which indicated that the 3/2 power law of self‐thinning holds for stem mass, branch mass and aboveground mass in overcrowdedP. densiflorastands.

Published: July 2011

AbstractOil of Gliricidia sepium with high contents of C18:2 (32.2 ± 0.3%) and C18:1 (23.8 ± 0.5%) fatty acids was used in the preparation of diethanolamide and epoxidised diethanolamide via transamidation. The epoxidised diethanolamide was synthesized by peroxyformic acid generated in situ by reacting formic acid and hydrogen peroxide with the oil of G. sepium, a renewable resource. The formation of the amide was monitored and confirmed using Fourier Transform Infrared Spectroscopy and Nuclear Magnetic Resonance. The epoxidised diethanolamide showed better surface‐active properties than the diethanolamide in terms of emulsion stability, wetting property and foaming power.
Radiology in paediatric non-traumatic thoracic emergencies
Authors: de Lange Charlotte 
Published: July 2011

Abstract
Non-traumatic thoracic emergencies in children are very frequent, and they usually present with breathing difficulties. Associated symptoms may be feeding or swallowing problems or less specific general symptoms such as fever, sepsis or chest pain. The emergencies always require a rapid diagnosis to establish a medical or surgical intervention plan, and radiological imaging often plays a key role. Correct interpretation of the radiological findings is of great importance in diagnosing and monitoring the illness and in avoiding serious complications. Plain radiography with fluoroscopy still remains the most important and frequently used tool to gain information on acute pulmonary problems. Ultrasound is the first choice for the detection and treatment of simple and complicated pleural effusions. Cross-sectional techniques such as multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are mainly used to study pulmonary/mediastinal masses and congenital abnormalities of the great vessels and the lungs. This article will discuss the choice of imaging technique, the urgency of radiological management and the imaging characteristics of acquired and congenital causes of non-traumatic thoracic emergencies. They represent common conditions involving the respiratory tract, chest wall and the oesophagus, as well as the less frequent causes such as tumours and manifestations of congenital malformations.
The Relationship History Calendar: Improving the Scope and Quality of Data on Youth Sexual Behavior

Published: July 2011

Abstract
Most survey data on sexual activities are obtained via face-to-face interviews, which are prone to misreporting of socially unacceptable behaviors. Demographers have developed various private response methods to minimize social desirability bias and improve the quality of reporting; however, these methods often limit the complexity of information collected. We designed a life history calendar—the Relationship History Calendar (RHC)—to increase the scope of data collected on sexual relationships and behavior while enhancing their quality. The RHC records detailed, 10-year retrospective information on sexual relationship histories. The structure and interview procedure draw on qualitative techniques, which could reduce social desirability bias. We compare the quality of data collected with the RHC with a standard face-to-face survey instrument through a field experiment conducted among 1,275 youth in Kisumu, Kenya. The results suggest that the RHC reduces social desirability bias and improves reporting on multiple measures, including higher rates of abstinence among males and multiple recent sexual partnerships among females. The RHC fosters higher levels of rapport and respondent enjoyment, which appear to be the mechanisms through which social desirability bias is minimized. The RHC is an excellent alternative to private response methods and could potentially be adapted for large-scale surveys.

AbstractGrowing evidence demonstrates the link between the quality of care nurses provide, patient outcomes, and nurses' level of qualification and expertise. Little attention has been given to measuring the influence of experience and education on nurses' perceptions of their perioperative competence. To describe the influence of years of OR experience and specialty education on nurses' perioperative competence, we surveyed 345 perioperative nurses from two Australian hospitals. We developed the 98‐item survey to specifically measure perioperative competence across eight domains that reflect knowledge, skills, and attitudes. We used multiple regression to analyze the data. There were differences in nurses' perceived perioperative competence based on perioperative experience and education, with more experienced nurses and those with specialty education reporting higher competence scores. Multiple regression analysis showed that experience and specialty education contributed to 23.3% of the variance in nurses' perception of their perioperative competence. Education initiatives are commonly used to address knowledge and attitudinal deficits; however, the results of this study suggest that education may only partly address these shortfalls. Hospital education programs should include staff development strategies associated with succession planning. Strategies that build on perioperative nurses' clinical experience and expertise will provide them with opportunites to develop skills in coordination and clinical leadership. Importantly, education occurs in a context and thus is embedded in clinical practice.
Dysfunctional coping in headache: Avoidance and endurance is not associated with chronic forms of headache

AbstractIntroductionAbout 4% of the population suffer from daily or near daily headache, which in most cases evolved from an episodic type of headache. The impact of psychological factors on this process is unknown. It seems reasonable to assume, that besides somatic and social conditions psychological factors like pain‐related coping and cognition play an important role, as has been shown for other pain conditions.MethodsWe performed a cross sectional study on pain coping behaviour in 211 patients with migraine and tension type headache. Pain‐related cognition and coping was investigated using the Kiel Pain Inventory. Prevalence of depression, medication intake and headache characteristics were analysed in regard to chronicity of headache.ResultsOverall pain intensity was high in the patient sample. The level of depression increased with headache frequency. Dysfunctional coping, characterized by fear and avoidance is frequently used by headache patients. As in low back pain, also endurance is highly prevalent. Other features known to be associated with chronic headache, like depression and medication overuse, could be confirmed.DiscussionDysfunctional coping was seen with high prevalence in the entire patient sample (66%). Against our hypothesis, it was not confined to chronic forms of headache. In respect to our data, we discuss the role of avoidance and endurance coping in headache and its possible role in chronicity.
Power and consumer behavior: How power shapes who and what consumers value
Authors: Rucker Derek D. , Galinsky Adam D. , Dubois David 
Published: July 2011

AbstractThe current paper reviews the concept of power and offers a new architecture for understanding how power guides and shapes consumer behavior. Specifically, we propose that having and lacking power respectively foster agentic and communal orientations that have a transformative impact on perception, cognition, and behavior. These orientations shape both who and what consumers value. New empirical evidence is presented that synthesizes these findings into a parsimonious account of how power alters consumer behavior as a function of both product attributes and recipients. Finally, we discuss future directions to motivate and guide the study of power by consumer psychologists.
Psychische Erkrankungen im Kontext von Arbeit
Authors: Friedrich-Gärtner Lene 
Published: July 2011

Einleitung
In Deutschland leidet rund ein Drittel der erwachsenen Bevölkerung im Laufe eines Jahres an einer psychischen Störung. Die Ursachen für diese Störungen sind i.d.R. multifaktoriell - jedoch liegen viele Ursachen für die Entstehung von psychischen Erkrankungen im Bereich der Arbeitsbedingungen und -organisation, sodass einer betrieblichen Prävention wachsende Bedeutung zukommt. Jedoch die Diskrepanz zwischen den wissenschaftlichen Erkenntnissen und der Umsetzung in der Praxis so groß ist wie in keinem anderen Bereich von betrieblicher Prävention.

Published: July 2011

AbstractA 51‐year‐old man complained of oral roughness and pain. At the age of 49 years, he was admitted for 8 months for bipolar emotional disorder. Oral administration of lithium carbonate was started. Extensive, hemorrhagic, erythema‐mixed white lace‐like patches were noted on the lip, buccal mucosae, and lingual margins. On biopsy, all lesions were consistent with oral lichen planus. A drug lymphocyte stimulation test showed a positive reaction to lithium carbonate. Blood examination revealed marked increases in the peripheral blood levels of antinuclear antibodies. To relieve the symptoms, the systemic administration of prednisolone was performed while continuing the lithium carbonate.
MANAGEMENT OF MEALYBUG (RHIZOECUS AMORPHOPHALLI) IN ELEPHANT FOOT YAM (AMORPHOPHALLUS PAEONIIFOLIUS)

Published: July 2011

SUMMARYAmorphophallus paeoniifolius, popularly known as elephant foot yam, is an important tropical tuber crop in India. Its modified stem (corm) is consumed as a vegetable after boiling, baking or frying. Mealybug (Rhizoecus amorphophalli), a soft-bodied insect, infests the corms both in storage and in the field. Though pesticides are effective in controlling mealybugs, they can be hazardous to human health and the environment. Two experiments, one in storage followed by one in the field, were conducted during 2009 and 2010 at the Regional Centre of Central Tuber Crops Research Institute, Dumuduma, Bhubaneswar, India, to determine the effect of six low cost and environmentally safe management practices on mealybug. In the absence of mealybug control measures, mealybug numbers increased by 4–5 times during the storage period. The pest affected the quality of the corms and reduced subsequent field establishment and crop growth. Salt (NaCl) solution (1000 ppm), cow urine, cow dung slurry (2 kg of cow dung in 1 litre of water) and clay slurry (1 kg of clay in 1 litre of water) treatments were effective in reducing mealybug numbers and the associated corm damage. However, availability of cow urine, cow dung and clay slurry limit their usage. Common salt is cheap, widely available and easy to use in treating the corms prior to storage. Relative to untreated corms, those treated with salt solution recorded greater emergence when field planted as well as producing plants with more vigorous growth.

AbstractA survey of the gastrointestinal helminth communities of a population of Chalcides sexlineatus Steindachner, a small skink endemic to Gran Canaria island (Canary Archipelago, Spain), was conducted to determine the prevalence, abundance and species diversity of intestinal parasites in these reptiles. Only three parasite species were found, one cestode, Oochoristica agamae Baylis, 1919 and two nematodes, Parapharyngodon micipsae (Seurat, 1917) and Pharyngodonidae gen. sp. Helminth infracommunities of C. sexlineatus showed low values of abundance and species richness and diversity, being more similar to the helminth community of Tarentola boettgeri boettgeri (Steindachner) rather than those of Gallotia stehlini (Schenkel), both syntopic with the sampled host.
Correlation between speech-evoked auditory brainstem responses and transient evoked otoacoustic emissions
Authors: Rana B , Barman A 
Published: July 2011

AbstractObjective:To investigate the correlation between cochlear processing and brainstem processing.Method:Transient evoked otoacoustic emissions and speech-evoked auditory brainstem responses were recorded in 40 ears of normal-hearing individuals aged 18 to 23 years. Correlation analyses compared transient evoked otoacoustic emission parameters with speech-evoked auditory brainstem response parameters.Results:There was a significant correlation between speech-evoked auditory brainstem response wave V latency and transient evoked otoacoustic emission global emission strength; there were no other significant correlations between the two tests.Conclusion:Tests for transient evoked otoacoustic emissions and speech-evoked auditory brainstem responses provide unique and functionally independent information about the integrity and sensitivity of the auditory system. Therefore, combining both tests will provide a more sensitive clinical battery with which to identify the location of different disorders (e.g. language-based learning impairments and hearing impairments).

Published: July 2011

AbstractObjective:To identify those patients most at risk of developing a compressive post-operative haematoma following thyroid surgery.Method:Retrospective analysis of patients undergoing thyroid surgery. Factors associated with the group of patients who developed a post-operative haematoma were examined using a matched pairs, case–control design.Results:Following 355 thyroid operations, seven patients developed a post-operative haematoma requiring return to the operating theatre for bleeding control. A post-operative systolic blood pressure of greater than 150 mmHg, in the post-anaesthetic care unit, was the major significant factor identified by regression analysis (p = 0.002). Current smoking status was also a significant factor (p = 0.04).Conclusion:In our facility, a post-anaesthetic systolic blood pressure in excess of 150 mmHg was associated with an increased risk of haemorrhage following thyroid surgery.
Continuum simulations of biomembrane dynamics and the importance of hydrodynamic effects
Authors: Brown Frank L. H. 
Published: July 2011

AbstractTraditional particle-based simulation strategies are impractical for the study of lipid bilayers and biological membranes over the longest length and time scales (microns, seconds and longer) relevant to cellular biology. Continuum-based models developed within the frameworks of elasticity theory, fluid dynamics and statistical mechanics provide a framework for studying membrane biophysics over a range of mesoscopic to macroscopic length and time regimes, but the application of such ideas to simulation studies has occurred only relatively recently. We review some of our efforts in this direction with emphasis on the dynamics in model membrane systems. Several examples are presented that highlight the prominent role of hydrodynamics in membrane dynamics and we argue that careful consideration of fluid dynamics is key to understanding membrane biophysics at the cellular scale.
The Value and Valuation of Maritime Cultural Heritage
Authors: Claesson Stefan 
Published: July 2011

AbstractMaritime cultural heritage is made up of finite and nonrenewable cultural resources including coastal or submerged prehistoric and indigenous archaeological sites and landscapes, historic waterfront structures, the remnants of seagoing vessels, and the maritime traditions and lifeways of the past and present. To date, evaluative tools used to assess the social and economic “value” of this heritage are extremely limited, the lack of which often results in the loss of maritime cultural resources and unrealized socioeconomic opportunities. Market and nonmarket valuations, derived from ecological economics and ecosystem assessments, are viable techniques that may be integrated into existing U.S. environmental and historic preservation regulatory procedures to support resource significance determinations. In doing so, decision-making regarding maritime cultural heritage can include assessments of the short- and long-term trade-offs of human actions, and can examine the socioeconomic costs and benefits of heritage conservation projects.
Anatomic biventricular repair by intraatrial and intraventricular re-routing in patients with left isomerism
Authors: Uemura Hideki , Yagihara Toshikatsu , Kawahira Youichi , Yoshikawa Yoshiro 
Published: July 2011

AbstractObjective: To determine the efficacy of anatomic biventricular repair by a combination of intraatrial and intraventricular re-routing in patients with isomerism of the left atrial appendages.Methods: Anatomic biventricular repair by means of combined intraratrial and intraventricular re-routing was achieved in 5 of the 63 patients with left isomerism in whom we attempted a definitive surgical procedure. The inferior caval vein was interrupted in 3. The Mustard procedure was chosen for intraatrial redirection of blood in 4, and the Senning procedure in the other. Intraventricular re-routing was carried out via a right ventriculotomy in all patients, using an external conduit to reconstruct the morphologically right ventricular outflow tract.Results: One patient died one month after the procedure because of low cardiac output and bronchial bleeding. Obstruction across the superior caval venous channel occurred after the Senning procedure in this particular patient, related to the interrupted inferior caval vein draining via the azygous vein. The other 4 patients are currently doing well. Postoperative catheterization showed excellent cardiac performance, with no obstruction across the venous channels or the ventricular outflow tracts in these 4. No episode of significant archythmia has been noted, all patients having a regular atrial rhythm, although the P wave vector was unusual in each patient. Reoperation has been needed thus far in one patient, 128 months after the initial repair, because of obstruction of the external conduit.Conclusion: With precise recognition of the morphologic features, a combination of intraatrial and intraventricular re-routing can successfully be established in patients with isomeric left atrial appendages, with functional results in the intermediate term being reasonable.
