Authors: Fernandes Mariana , Almeida Paz Filipe A. , de Zea Bermudez Verónica 
Published: April 2012

AbstractThe cover picture shows that the morphology of CaCO3 may be finely tailored through its precipitation in ethanol by using calcium chloride, ammonium carbonate and an ionic liquid (IL). Calcite nanocorn‐like objects were produced with a chloride‐based IL, whereas calcite and fluorite nanostructured calla‐lily‐like and ice‐cream‐ball‐like micro‐objects were obtained with a tetrafluoroborate‐based IL. Details are discussed in the article by V. de Zea Bermudez et al. on p. 2183 ff. magnified image
Synthesis of 2,6‐Disubstituted Imidazo[2,1‐b][1,3,4]thiadiazoles through Cyclization and Suzuki–Miyaura Cross‐Coupling Reactions
Authors: Copin Chloé , Henry Nicolas , Buron Frédéric , Routier Sylvain 
Published: April 2012

AbstractHighly substituted imidazo[2,1‐b][1,3,4]thiadiazole derivatives were synthesized through successive cyclization and Suzuki–Miyaura cross‐coupling reactions. The palladium‐catalyzed coupling reaction was optimized and a wide range of boronic acids was used to evaluate the scope and limitations of the methodology. The final compounds were obtained in fair to very good yields and high compatibility with various chemical functions or (hetero)cycles was observed.
In Situ Dearomatisation/Alkylation of Arylphosphane Derivatives (Eur. J. Org. Chem. 13/2012)
Authors: Stankevič Marek , Wójcik Karolina , Jaklińska Magdalena , Pietrusiewicz K. Michał 
Published: April 2012

AbstractThe cover picture shows the in situ dearomatisation/alkylation of the aryl substituent in aryldialkylphosphane–borane by a solution of alkali metal in liquid ammonia and alkyl halide. This leads to the formation of α‐substituted (1,4‐cyclohexadien‐3‐yl)phosphane–borane where the “unreactive” phenyl substituent is replaced by a cyclohexadienyl fragment possessing a functionality in the α‐position. This reaction sequence can be regarded as a versatile tool in the “activation” of the aryl substituent in organophosphorus compounds both through aromaticity breaking and introduction of new functionalities at the quaternary α‐carbon atom. Details are discussed in the article by M. Stankevič et al. on p. 2521 ff. The authors would like to express their gratitude to Katarzyna Jaklińska for her efforts during the preparation of the cover picture. magnified image
Tissue penetration of bipolar electrosurgical currents: Joule overheating beyond the surface layer
Authors: Habermann Walter , Müller Wolfram 
Published: April 2012

AbstractBackgroundThere is extensive evidence that electrosurgical current application increases hemorrhage when compared with “cold” dissection and hemostasis. The way that the “hot” technique is used may influence the outcome decisively.MethodsTemperature‐time functions were measured in distances of 3 to 12 mm underneath the surface at which bipolar electrosurgical current was applied. Measurements were made in human cadaver, excised pig tissues, and pig animal models.ResultsBipolar current causes Joule heating in distances of several millimeters. A single maximum power pulse of 1 second increased the temperature in the muscle in 3 and 6 mm distance to 90° and 65°C, respectively; similar accumulated thermal effects were detected for a series of low‐ and medium‐power pulses, too.ConclusionJoule heating is primarily responsible for unintended thermal damages. Severe damages can easily occur even in several millimeters distance from the forceps tips. Utmost caution is also advised at low power setting when current is applied repetitively. © 2012 Wiley Periodicals, Inc. Head Neck, 2013

AbstractBackgroundThe purpose of this study was to present our findings on the impact of the Blom tracheotomy tube with speech inner cannula on voice production abilities and speech intelligibility scores of ventilator‐dependent patients requiring a fully inflated tracheotomy tube cuff.MethodsProspective single group case‐series design permitted consecutive accrual of 23 adult inpatients from acute care and rehabilitation settings. Maximum ambient room noise, voice intensity, phonation duration of vowel /a/, and speech intelligibility scores were determined over 3 sessions.ResultsAll participants achieved audible voicing with the Blom tracheotomy tube. Voice intensity was significantly greater than ambient room noise by >10 dB SPL (p = .003). Speech intelligibility scores improved significantly from 80% to 85% (p = .03). Phonation duration averaged from 3.30 to 3.45 seconds. There were no significant changes in oxygen saturation (p > .05), and no significant complications occurred.ConclusionThe Blom tracheotomy tube with speech inner cannula permitted individuals requiring mechanical ventilation with a fully inflated tracheotomy tube cuff to produce excellent speech intelligibility for verbal communication. © 2012 Wiley Periodicals, Inc.

Therapeutic play within infant–parent psychotherapy and the treatment of infant feeding disorders
Authors: Jordan Brigid 
Published: April 2012

AbstractThis clinical article presents an infant mental health approach to the treatment of feeding disorders in infants and toddlers that involves the infant–parent psychotherapist directly working with the infant's representations within infant–parent psychotherapy sessions. The treatment is informed by an assessment of the infant's emotional development, subjective experience, and the dynamics of the infant–parent relationship. This model involves therapeutically using play and words with infants and draws upon concepts from D.W. Winnicott and attachment theory as well as principles from the psychodynamic treatment of posttraumatic stress disorder in infants. The model was developed from clinical work over 2 decades in a tertiary pediatric hospital with infants who presented with feeding disorders ranging from breast or bottle refusal, refusal to wean onto solids, feeding aversion, tube dependency, and failure to thrive.
The consultation relationship—From transactional to transformative: Hypothesizing about the nature of change
Authors: Johnston Kadija , Brinamen Charles F. 
Published: April 2012

AbstractIncreasing numbers of young children with significant social and emotional difficulties are being identified in childcare settings. Early Childhood Mental Health (ECMH) Consultation has been identified as a promising practice in stemming the tide of this troublesome trajectory. While ECMH Consultation is credited with promoting children's positive development, diminishing difficult behaviors, and reducing expulsion rates, the mechanisms of this transformative process are only beginning to be investigated. Recent research cites the salience of the relationship between a consultant and consultee as the central contributor to positive change in childcare‐center climate and child outcomes. This article delineates characteristics of a beneficial consultative relationship and postulates the clinical process by which change in childcare providers' behavior occurs as a result of having experienced such a relationship. Paralleling the traits of contingent caregiving, the consultative stance, a posture of mutuality, reciprocity, and positive regard creates an intersubjective space for reflection, repair, and, when necessary, adaptation. Based on perceptual shifts or expansions, the providers' attitude and approach toward children in their care is amended, in turn promoting positive change in the child and classroom atmosphere.
A multilevel analysis of consultant attributes that contribute to effective mental health consultation services
Authors: Allen Mary Dallas , Green Beth L. 
Published: April 2012

AbstractA positive relationship between the mental health consultant (MHC) and early care and education staff is considered important for achieving positive early childhood mental health consultation outcomes, but little is known about the attributes of MHCs that contribute to relationships with staff and to staff‐reported child outcomes. This study was a secondary analysis of 57 MHCs and 407 Head Start staff who responded to the Head Start Mental Health Services Survey. Hierarchical linear models examined the relationship between five attributes of MHCs and staff reports of improved child outcomes and a positive relationship with the MHC. The results suggest that MHC reports of positive relationships with staff, positive relationships with families, and high levels of supervision and support are positively associated with staff reports of positive relationships with the MHC (p < .05). None of the MHC‐reported attributes were associated with staff‐reported child outcomes.

Published: April 2012

AbstractThe aim of the current study was to examine the effects of early childhood mental health consultation (ECMHC) on teacher‐level and child‐level outcomes in the context of a partnership between community mental health centers in three regions of Arkansas and publically funded early education programs (14 intervention sites and 4 comparison sites). From 2005 to 2008, 193 teachers participated in the study, along with 1,448 children. Data‐collection activities included structured classroom observations, teacher ratings of children's strengths and behavior, and teacher surveys to assess satisfaction with ECMHC services. Results suggest that teachers were highly satisfied with the consultation services and that teachers receiving the intervention had lower levels of permissiveness and detachment, with a trend toward higher levels of sensitivity in interactions with children in their classroom. In terms of child outcomes, we found that by the third year of the project, children at intervention sites were rated by their teachers as having fewer behavior problems and more protective factors.

AbstractState‐ and local‐level mental health administrators and practitioners can work collaboratively to provide effective early childhood mental health consultation (ECMHC) services that address the growing need in communities to promote healthy socioemotional functioning in infants and young children and prevent longer term mental health challenges. This article describes one state's model of ECMHC, the Child Care Expulsion Prevention Program (CCEP), as well as preliminary evaluation findings on consultants' fidelity to the developed approach to service within 31 counties in Michigan. The CCEP approach is flexible, yet adheres to six cornerstones which are essential to effectively and consistently carrying out services across local projects, including the provision of relationship‐based programmatic and child/family‐centered consultation, hiring and supporting high‐quality consultants through professional development and reflective supervision, ongoing provision of state‐level technical assistance, use of evidence‐based practices, and collaboration with other early childhood service providers. In addition to the overview of CCEP's approach and effectiveness, lessons learned are provided to guide those engaged in policy development, practice, and applied research pertaining to ECMHC.Abstracts translated in Spanish, French, German, and Japanese can be found on the abstract page of each article on Wiley Online Library at http://wileyonlinelibrary.com/journal/imhj.
Assessing fidelity for early childhood mental health consultation: Lessons from the field and next steps
Authors: Kaufmann Roxane K. , Perry Deborah F. , Hepburn Kathy , Duran Frances 
Published: April 2012

AbstractEarly childhood mental health consultation (ECMHC) has become a common approach to delivering mental health services and supports for young children, their families, and the early care and education community. While many states and communities are implementing some form of ECMHC, the evidence base is still developing. One obstacle to building a rigorous evidence base has been a lack of focus on fidelity measurement, and one barrier to fidelity assessment has been a lack of a common framework for the essential components of effective ECMHC. This article briefly summarizes the development of a conceptual model for effective ECMHC based on a qualitative study of six ECMHC programs with positive outcomes (F. Duran et al., 2009). The common components and processes derived from those six programs are then used to articulate an approach for operationalizing fidelity. Specific examples of strategies used to support fidelity by three of the six programs are highlighted. We close with a discussion of the implications of these approaches and suggestions for next steps in defining a consensus‐based model for measuring fidelity to ECMHC services.Abstracts translated in Spanish, French, German, and Japanese can be found on the abstract page of each article on Wiley Online Library at http://wileyonlinelibrary.com/journal/imhj.
LOSS of Mrp1 alters detoxification enzyme expression in a tissue‐ and hormonal‐status‐specific manner
Authors: Sivils Jeffrey C. , Ancrum Tiffany M. , Bain Lisa J. 
Published: April 2012

ABSTRACTThe multidrug resistance‐associated protein1 (MRP1/ABCC1) is a member of the ABCC transporter subfamily that mediates the efflux of pharmaceuticals, xenobiotics and steroid hormones, typically as glutathione, glucuronide or sulfate conjugates. Since loss of one transporter can be compensated by increasing the expression of other transporters and conjugation enzymes, we sought to examine compensatory changes in phase I, II and III enzyme expression in extrahepatic tissues, including the kidney, lungs and small intestine of intact or castrated Mrp1−/− male mice. In the kidney, the expression of several P450s, sulfotransferase 1a1 (Sult), glucuronosyltransferases (Ugt) and Mrps2–4, were significantly changed owing to castration alone. The only time genotype mattered was between the castrated FVB and Mrp1 knockout mice. In contrast, expression of the Ugts, Sult 1a1 and Mrp3 in the lungs was significantly downregulated in the Mrp1 knockout mice, so based exclusively on genotype. In the small intestine, there were interactions between steroid hormone levels and genotype, as the expression differences were only found in mice lacking Mrp1, and were changed between intact and castrated animals. The mechanism behind this pattern of expression may be to due to Nrf2 regulation, as its expression mirrors that of the phase II and phase III enzymes. These results indicate that compensatory responses owing to the loss of Mrp1 vary dramatically, depending on the particular tissue. This information will aid in the understanding of how drug uptake, disposition and elimination can be influenced by both hormone status and the presence and magnitude of transporter expression.

Published: April 2012

AbstractThe past ten years have witnessed a remarkable transformation in the way companies and customers interact with one another. Almost every office and household has an Internet connection along with some type of wireless capability. But everything comes at a price, and we pay for our increased computer speed and efficiency with new opportunities for fraudsters.However, people conducting routine digital activities do leave an information trail. Under the right circumstances, this digital library of automatically generated data can be used to detect fraud or misuse of company resources. So, many companies are using Link Analysis (LA) as an effective tool for organizing this digital information when looking for fraud or employee misconduct.This article presents an overview of LA—and explains how your company can use it to detect possible fraud. © 2012 Wiley Periodicals, Inc.

AbstractIdentifying and recovering vendor credits is a much bigger problem than you might imagine. Most JCAF readers are well versed in accounting issues, and probably believe they are recovering all the vendor credits their company or their clients are entitled to. Unfortunately, says the author of this article, the data shows something entirely different. Vendor credits are evaporating at an alarming rate, and their rightful owners are not even aware of it.What can you do to audit and recover these credits? The author has some answers. © 2012 Mary S.

Published: April 2012

AbstractEthics training and education usually assume that people recognize when they encounter ethical situations—and that a better understanding of ethics results in better ethical decisions. But these assumptions are false! Instead, the authors suggest other approaches to improve ethical decision making by auditors. And although this article focuses on auditing, it also applies to other business and nonbusiness situations. © 2012 Wiley Periodicals, Inc.

Published: April 2012

AbstractBACKGROUND: Immobilized cultivation of microorganisms is gaining interest in the microalgae industry. In this study, a novel microalgae polymeric carrier, sodium cellulose sulphate/poly‐dimethyl‐diallyl‐ammonium chloride (NaCS‐PDMDAAC) capsule system, was employed to immobilize Chlorella sp. Microalgae cultivation was performed under immobilized and suspended conditions, and the resulting cells were characterized biochemically and physically.RESULTS: Experimental results indicated that microalgae cells cultivated under NaCS‐PDMDAAC immobilized conditions have a robust morphology, a smaller average cell size of 2.92 µm and a higher Zeta potential of − 17.10 mV than the suspended cells with a cell size of 6.81 µm and Zeta potential of − 32.90 mV. The immobilized microalgae cells displayed a total lipid content of 14.85%, and a chlorophyll content of 3.36%, slightly higher than those obtained from the suspended cells.CONCLUSION: These differences are critical to further explore the impact of immobilized microalgae cultivation systems for specific biotechnological applications. © 2012 Society of Chemical Industry

AbstractThe myotendinous junction (MTJ) is a major area for transmitting force from the skeletal muscle system and acts in joint position and stabilization. This study aimed to use transmission electron microscopy to describe the ultrastructural features of the MTJ of the sternomastoid muscle in Wistar rats from newborn to formation during adulthood and possible changes with aging. Ultrastructural features of the MTJ from the newborn group revealed pattern during development with interactions between muscle cells and extracellular matrix elements with thin folds in the sarcolemma and high cellular activity evidenced through numerous oval mitochondria groupings. The adult group had classical morphological features of the MTJ, with folds in the sarcolemma forming long projections called “finger‐like processes” and sarcoplasmic invaginations. Sarcomeres were aligned in series, showing mitochondria near the Z line in groupings between collagen fiber bundles. The old group had altered “finger‐like processes,” thickened in both levels of sarcoplasmic invaginations and in central connections with the lateral junctions. We conclude that the MTJ undergoes intense activity from newborn to its formation during adulthood. With increasing age, changes to the MTJ were observed in the shapes of the invaginations and “finger‐like processes” due to hypoactivity, potentially compromising force transmission and joint stability.

Morphology of immature stages of Megaselia spiracularis Schmitz (Diptera: Phoridae)
Authors: Dian‐Xing Feng , Guang‐Chun Liu 
Published: April 2012

AbstractIn addition to causing myiasis in humans, Megaselia spiracularis Schmitz has also been reported as a forensically important fly. In this study, we presented the morphology of all larval instars and puparium of M. spiracularis using scanning electron microscopy. The first instar larva was composed of 12 segments. Antennae and maxillary palp complex were visible. Two spiracular slits could be seen at the posterior spiracle. The branch of posterior spiracular hairs was approximately equal to the palm‐formed base in length. Second and third larval instars were very similar to first instar, except for the presence of anterior spiracle. The labium of the second instar larva was triangular and ventrally curved, whereas it was a bilobed structure and the tip forked in the first instar. The bubble membrance comprised of ≈40 globules presented at the third instar larvae. Puparia showed a retracted cephalic region and a pair of pupal respiratory horns on the dorsum. A comparison of the morphological features between immature stages of M. spiracularis and M. scalaris, a forensically important fly indoors in Germany, Malaysia, and China, was discussed. Microsc.
