Vertical Scope, Turbulence, and the Benefits of Commitment and Flexibility
Authors: Claussen Jörg , Kretschmer Tobias , Stieglitz Nils
Published: August 2014

We address the contested state of theory and the mixed empirical evidence on the relationship between turbulence and vertical scope by studying how turbulence affects the benefits of commitment from integrated development of components and the benefits of flexibility from sourcing components externally. We show that increasing turbulence first increases but then decreases the relative value of vertical integration. Moderate turbulence reduces the value of flexibility by making supplier selection more difficult and increases the value of commitment by mitigating the status quo bias of integrated structures. Both effects improve the value of integration. Higher levels of turbulence undermine the adaptive benefits of commitment, but have a less adverse effect on flexibility, making nonintegration more attractive. We also show how complexity and uneven rates of turbulence moderate the nonmonotonic relationship between turbulence and integration.

Published: August 2014

It is indeed an honor to have been selected as the new editor-in-chief of Manufacturing & Service Operations Management. I look forward to my term of duty, and I am pleased to describe my plans for the journal.

However, before doing so, I would first like to personally thank founding and outgoing Editor-in-Chief Leroy B. Schwarz for the superb job he has done in launching this journal. In the last four years, M&SOM has blossomed from a nonentity into the leading specialized journal in the field of operations management (OM). This is largely due to Lee's efforts and vision. We all owe him a tremendous debt of gratitude for this accomplishment. As incoming editor, I am especially indebted to Lee for the excellent reputation and goodwill he has generated for the journal. His will certainly be a tough act to follow.

Like Lee, I truly believe the continued success of M&SOM is critical for our field. This is why I accepted the position of editor and why I am committed to making the journal an even greater success in the future. This task will no doubt require adjustments and revisions as time progresses. However, let me described my assessment of where the journal stands currently and my strategies and policies going forward.
The health care assistant: usurper of nursing?
Authors: Edwards Margaret
Published: August 2014

Concerns have been expressed that the nursing role is being usurped by health care assistants. However throughout history unqualified workers have made a sizable contribution to nursing care and particularly that of the elderly. It is argued that therapeutic care can only be delivered by qualified nurses who should in future be graduates. research however demonstrates that when unqualified nurses work with and are supervised by trained nurses who display the appropriate therapeutic approach they can deliver high quality care. The demographic and economic position suggest that there are never likely to be sufficient qualified nurses to meet the nursing needs of an increasingly ageing population. Patient need is most likely to met by nurses who are prepared to accept a supervisory training role. In the community this will involve demanding a role in the supervision of social service care assistants as well as those working in nursing teams.
Practical use of the Waterlow tool in the community
Authors: Waterlow Judy
Published: August 2014

In the first paper of this focus, Judy Waterlow discusses her views on community use of the Waterlow pressure sore risk tool (Waterlow 1988). The author suggests it is essential that pressure sore risk assessment systems are seen as tools to be used as part of the decision making process to identify people at risk of developing sores. They should not be seen as calculators, which can single handedly predict pressure sore development. Provided that assessors understand its function, the Waterlow pressure sore risk assessment tool may be used successfully in the community, despite being developed in a hospital environment.
What to expect when you're expecting? Representations of birth in British newspapers
Authors: Maclean Emily
Published: August 2014

Background: National newspapers are a powerful force in British society, often portraying childbirth as a moment of high drama. Yet no evidence to date has systematically collated the material on offer.

Objective: This descriptive study aimed to examine how childbirth is represented in British national newspapers.

Methods: Content analysis of women's first-person accounts of birth was carried out. Text was coded using material gleaned from a database search of 23 publications over 12 months (from 1 December 2011 to 30 November 2012). Publications included Daily Mail, Mirror, The Telegraph, The Guardian, The Sun and The Times.

Results: 61 codes emerged, including; fear, ordeal, pain, effective staff, malicious or poor care, intervention, humour, positive pain, relief, no choice, infection, no pain, mother's instinct.

Conclusions: A discrepancy exists between newspaper messages and the majority of births. Uptake of normal birth pathways arguably depends on midwives addressing this potential source of anxiety. Distorted risk perceptions may also affect the behaviour of health practitioners, managers and commissioners.

Angiotensin receptor blockers as an alternative in heart failure
Authors: O'Donovan Kate
Published: August 2014

Angiotensin II plays a pivotal role as a compensatory mechanism in heart failure with reduced ejection fraction and in the development of symptoms such as fluid retention. Angiotensin II receptor blockers (ARBs) can be used as an alternative to angiotensin-converting enzyme (ACE) inhibitors in patients in whom a cough develops, as well as for additional therapy in patients who have symptoms that persist despite receiving optimal beta-blockade and ACE inhibition. Although clinical trials of ARBs have not demonstrated superiority over ACE inhibitors they are classified as second-line therapy in this patient population. Similar to ACE inhibitors, common adverse effects include hypotension, renal dysfunction and hyperkalaemia. Nursing care of patients prescribed ARBs involves cardiovascular assessment including volume status, improvement or deterioration in clinical symptoms and biochemical monitoring.
Intrabony Defects and Non-Surgical Treatment
Authors: Nibali Luigi
Published: August 2014

Periodontitis can lead to vertical bone loss with the creation of ‘intrabony defects’, associated with higher risk of progression if left untreated. Intrabony defects are considered candidates for periodontal surgical procedures, in order to arrest disease progression and achieve bone regeneration. This paper brings forward anecdotal and scientific evidence from the literature to describe how even non-surgical periodontal treatment can result in clinical and radiographic resolution of periodontal intrabony defects.

Authors: Tapilouw Abraham Mario , Chen Liang-Chia , Xuan-Loc Nguyen , Chen Jin-Liang
Published: August 2014

A Micro-electro-mechanical-system (MEMS) is a widely used component in many industries, including energy, biotechnology, medical, communications, and automotive industries. However, effective inspection systems are also needed to ensure the functional reliability of MEMS. This study developed a stroboscopic coherence scanning Interferometry (SCSI) technique for measuring key characteristics typically used as criteria in MEMS inspections. Surface profiles of MEMS both static and dynamic conditions were measured by means of coherence scanning Interferometry (CSI). Resonant frequencies of vibrating MEMS were measured by deformation of interferogram fringes for out-of-plane vibration and by image correlation for in-plane vibration. The measurement bandwidth of the developed system can be tuned up to three megahertz or higher for both in-plane and out-of-plane measurement of MEMS.

Published: August 2014

The XN-Series (Sysmex, Kobe, Japan) have been equipped with the automated digital cell imaging analyzer DI-60, which provides complete automation of the sample processing with automated complete blood counts (CBC), slide making/staining, and digital scanning with cell pre-classification. The aim of this study was to evaluate the efficacy of the XN-Series as an integrated blood cell analysis system.

White blood cell (WBC) morphological analysis by the DI-60 was evaluated using 232 blood samples from patients. Routine analysis of a total of 2000 blood samples has been performed to evaluate the processing ability of the XN-Series connected to the DI-60.

The overall analysis accuracy of pre-classification of WBC by the DI-60 was 88.4%. Good correlation was observed between final results of the DI-60 analysis and manual differentiation with high sensitivity and specificity for blasts and immature granulocytes. The sample processing time of the XN-Series, from automated CBC to cell pre-classification, was 38±1 min/single run and 165±12 min/500 CBC samples run (slide preparation rate 15.6%) with no sample hold-up at the DI-60.

The automated morphological analysis capability of the DI-60 has potential usefulness in the integrated automated hematology analysis system of XN-Series.
Diagnostic testing for a high-grade inflammation: parameter dynamics and novel markers
Authors: Hoffmann Christina , Hoffmann Peter , Zimmermann Mathias
Published: August 2014

The timely detection of severe inflammatory conditions is of great importance for early therapy initiation and the patient’s prognosis. The complex humoral and cellular processes involved in inflammation offer many opportunities for diagnostic testing, which are still unused in clinical practice. We investigated the dynamics of four established and two novel potential markers during the onset and resolution of a high-grade inflammation.

We retrospectively analyzed C-reactive protein and procalcitonin concentrations, leukocyte and thrombocyte counts, granularity index, and δ-hemoglobin measured in peripheral blood samples of patients undergoing inflammation diagnostics between September 2010 and November 2010. Data from a consecutive sample of 53,968 patients were available.

Trajectories for the parameters’ dynamics during the onset and resolution of a high-grade inflammation were calculated with a locally weighted scatter plot smoothing method. The leukocyte count trajectories did not exceed the reference range.

We were able to elucidate the parameter dynamics with time coordinates rounded to the nearest hour and a follow-up of 168 h.
Serological features of antibodies to protamine inducing thrombocytopenia and thrombosis
Authors: Panzer Simon , Schiferer Arno , Steinlechner Barbara , Drouet Ludovic , Amiral Jean
Published: August 2014

A significant proportion of patients undergoing cardiopulmonary bypass develop anti-protamine antibodies, with or without the association of thromboembolic events.

We extensively investigated the serological features of protamine antibodies, which developed in six patients who were clinically suspected to have heparin-induced thrombocytopenia (HIT). Three patients had thrombotic events. Sera were tested by four different commercially available immunoassays, a heparin-platelet aggregation test, and for their binding properties to heparin, platelet factor 4 (PF4), complex heparin-PF4, protamine, and protamine complex with heparin. Sera from four patients were also tested for the capability to induce platelet activation and the formation of platelet-monocyte heterotypic aggregates.

The ELISA assay Zymutest HIA was strongly positive in all cases, the HPIA Asserachrome was borderline, and the gel centrifugation test PaDGIA was positive in two tested patients. Platelet aggregation tests were negative. Using a variation of the Zymutest HIA we demonstrate that IgG antibodies bound only to protamine or protamine complex with heparin, but not to heparin or PF4 only. Sera-induced platelet P-selectin expression and the formation of platelet-monocyte aggregates. Blood samples from one patient proofed positive concomitantly with the thromboembolic event. However, serological characteristics did not differ between antibodies associated with thromboembolic events from those without.

These data show that protamine-induced antibodies are specific and may induce platelet activation, which explains their association with thromboembolic events.
Characterization of the Robin function by extremal problems
Authors: Dittmar Bodo
Published: August 2014

In [`Robin function and conformal welding – A new proof of the existence', submitted] a new proof of the existence of the Robin function is given using conformal welding. This proof is essentially based on the simply connected case and a conformal mapping which maps the domain onto a complement of a disk and a system of radial spires.
The aim of this note is to show that this proof also has a wider meaning, namely that this mapping is the unique solution of extremal problems, which minimizes the length or the diameter of a subset of the boundary curve. As a consequence we obtain sharp inequalities for the Robin capacity and the logarithmic capacity.
Analysis of cold temperature effect on stress wave velocity in green wood
Authors: Xu Huadong , Wang Lihai
Published: August 2014

The objective of this study was to investigate the effect of temperature on stress wave velocity (SWV) in green wood below zero degress centigrade (0°C). Both field and laboratory tests were conducted on standing Korean pine trees and small wood samples to study the effects of low temperature at various moisture content (MC) on SWV. As expected, SWV in wood increased with decreasing temperature. However, near 0°C, the SWV increment was not linear but showed disproportional high increments at MCs above 50%. To explain this phenomenon, differential scanning calorimeter (DSC) measurements were performed at various MCs and temperatures, i.e., the interrelation between the state of water aggregation and SWV was analyzed. The explanation of the irregular behavior of SWV as a function of temperature is straightforward: free water and a small portion of bound water in green wood are transformed from water to ice below zero degrees (0°C) centigrade. Thus the disproportional high SWV increment below 0°C reflects the aggregation change of water because the SWV in ice is higher than that in liquid water.

Published: August 2014

We have raised monoclonal antibodies against KLK6 and constructed a ‘sandwich’ type immunoassay using 8A8G3 as capture and 3H3E9 as tracer antibodies. 8A8G3 bound to one side of KLK6, whereas 3H3E9 probably bound near its catalytic site. The assay did not detect complexed forms of KLK6, indicating that it quantifies only free KLK6 (fKLK6). fKLK6 was higher in serum of patients with ovarian cancer (11.34 μg/l±1.37) than in controls (3.39 μg/l±0.42). The cerebrospinal fluid contained high concentrations of fKLK6 (257–965 μg/l). This assay could facilitate the evaluation of fKLK6 in human diseases.

Published: August 2014

The prognosis of patients following surgery for gastric cancer is often poor and is estimated using traditional clinicopathological parameters, which can be inaccurate predictors of future survival. Kallikreins are a group of serine proteases, which are differentially expressed in many human tumors and are being investigated as potential cancer biomarkers. This study assessed the prognostic utility of human tissue kallikrein-like peptidases 6 and 10 (KLK6 and KLK10) and correlated their expression with histopathological and clinical parameters in gastric cancer. We constructed a gastric tumor tissue microarray from 113 gastrectomy specimens and quantified KLK6 and KLK10 expression using immunohistochemistry. To overcome the problem of inter-observer variability and subjectivity in immunohistochemistry interpretation, a whole-slide scanned image of the tissue microarray was analyzed using an automated algorithm to quantify staining intensity. KLK6 expression was positively correlated with nodal involvement (p=0.002) and was predictive of advanced-stage disease (p<0.05). Kaplan-Meier survival curves revealed that tumors expressing high levels of KLK6 were significantly associated with significantly lower overall survival (p=0.04). KLK10 overexpression was also a predictor of advanced-stage disease (p<0.01), but was not significantly correlated with lymph node involvement or survival period. Our results show the potential ability of KLK6 as a prognostic marker for gastric cancer.

Approximately Unbiased Estimator for Non-Normal Process Capability Index CNpk
Authors: Pearn W. L. , Tai Y. T. , Hsiao I. F. , Ao Y. P.
Published: August 2014

Process capability indices (PCIs) have been extensively used to evaluate and measure whether the process meets the specifications and they provide quality assurance and guide a principal for quality improvement. The index Cpk is the most popular index and is widely used in the manufacturing industry for manufacturing yield evaluation. However, typical evaluations of Cpk depend heavily on the assumption of normal variability. When the underlying distributions are non-normal, the capability evaluations are highly unreliable. In the paper, we apply four various bootstrap methods to construct lower confidence bounds of CNpk for non-normal processes. We also propose an approximately unbiased estimator of CNpk for the non-normal processes. Comparisons among the four bootstrap methods with different estimators are provided.
Epigenetic memory in plants
Authors: Iwasaki Mayumi , Paszkowski Jerzy
Published: August 2014

Epigenetics refers to heritable changes in patterns of gene expression that occur without alterations in DNA sequence. The epigenetic mechanisms involve covalent modifications of DNA and histones, which affect transcriptional activity of chromatin. Since chromatin states can be propagated through mitotic and meiotic divisions, epigenetic mechanisms are thought to provide heritable ‘cellular memory’. Here, we review selected examples of epigenetic memory in plants and briefly discuss underlying mechanisms.

Constantin Stanca (1889-1969) was the first director of the Institute for the Study and Prevention of Cancer from Cluj between 1929 and 1940 and the founder of the Gynecologic Oncology Surgery Department of this Institute. During his important career in gynecology and surgical oncology, which took place in Cluj and in Bucharest, he was also interested in medical sociology and in social medicine. Our paper presents some of Stanca’s objectives in these domains: to increase the health status of women, to prevent gynecological diseases and to improve women’s working conditions, especially in factories.
REGIME DE TRANSPORTE DE POLPA DE MOINHO ISAMILL EM ESCALA DE LABORATÓRIO
Authors: Mazzinghy Douglas Batista
Published: August 2014

O moinho IsaMill tem se mostrado eficiente em etapas de remoagem. Isso ocorre porque os moinhos deste tipo permitem a utilização de corpos moedores muito pequenos em relação a outros tipos de moinhos, notoriamente o moinho tubular de bolas e o VertiMill. Corpos moedores de pequeno diâmetro implicam em eficiência maior na moagem de partículas finas. Neste trabalho foram realizados quatro ensaios de moagem contínuos, em condições diversas, com duas amostras de minério de cobre com granulação distinta. A determinação da distribuição de tempos de residência da fase líquida realizou-se com um ácido como traçador e medidas de pH no produto do moinho de laboratório de um litro. Os resultados obtidos indicam que o moinho IsaMill de laboratório apresenta um padrão de distribuição de tempo de residência de fluxo pistão e deverá se comportar similarmente a um moinho de barras do ponto de vista de transporte.
AVALIAÇÃO DA CAPACIDADE ADSORTIVA DE CARVÃO ATIVADO PARA A REMOÇÃO DE MANGANÊS
Authors: Godoy Perilli Thomaz Antônio , Sicupira Dalila Chaves , Mansur Marcelo Borges , Queiroz Ladeira Ana Cláudia
Published: August 2014

A possibilidade de remoção de manganês contido em efluentes de mineração de elevada concentração, i.e., até 140mg/L, foi estudada através de adsorção em carvão ativado. Inicialmente, foi feito um tratamento térmico no carvão em duas temperaturas distintas, com o intuito de avaliar a importância dos sítios de adsorção no processo. Os ensaios de adsorção foram conduzidos em batelada, utilizando-se uma solução de laboratório para simular os altos níveis de manganês típicos de drenagem ácida de mina. Os resultados mostraram que os carvões tratados termicamente apresentaram queda de capacidade adsorvente. Análises da superfície específica dos materiais e do ponto de carga zero apontam para um mecanismo de quimiossorção, em acordo com o mecanismo de troca catiônica proposto em outros estudos. A decomposição de sítios ativos de adsorção durante o tratamento térmico pode explicar a redução na remoção do manganês entre os carvões tratados e o carvão in natura. Em nenhum dos casos testados a solução atingiu a concentração permitida pela legislação brasileira, de 1mg/L, sendo o melhor resultado 20mg/L.
PROJETO DE CORREIAS TRANSPORTADORAS: UM ESTUDO COMPUTACIONAL DE COMPARAÇÃO DOS MÉTODOS CEMA E PRÁTICO
Authors: Amâncio Malagoni Ricardo , Santos Dyrney Araújo dos
Published: August 2014

Para o projeto de correias transportadoras, são comumente empregados dois métodos: Método Prático e Método CEMA (Conveyor Equipment Manufacture Association). O Método Prático, mais simplificado, aplica-se a transportadores simples e de pequena capacidade. Neste, calcula-se primeiramente a potência necessária para o transporte e, a partir desta, as tensões na correia. O método CEMA, mais sofisticado, é aplicável a transportadores de vários lances, curtos ou longos, onde calcula-se inicialmente as tensões em cada lance da correia, e, após isto, calcula-se a potência de acionamento. Com isto, um dos objetivos do presente trabalho foi a criação de um programa computacional, o qual realiza o projeto de correias transportadoras através dos métodos Prático e CEMA. Por meio deste programa, foram realizadas simulações para os materiais: rocha fosfática e minério de ferro (itabiritos) para diferentes configurações de correias transportadoras. Como dados de saída do programa, tem-se as seguintes especificações de projeto: largura da correia, distância do material à borda da correia, capacidade mássica, velocidade da correia e potência do motor. Tanto o Método Prático quanto o Método CEMA se mostraram de suma importância para o projeto de correias transportadoras, sendo o primeiro de grande valia na estimativa inicial de um projeto, enquanto o outro, apesar da maior complexidade, é o mais recomendado para o projeto final de correias transportadoras.

A Clinical Report on the Use of Closed-Tray, Hex-Lock-Friction-Fit Implant Impression Copings
Authors: Raviv Eli , Hanna Jan , Raviv Roy , Harel-Raviv Mili
Published: August 2014

The precision of an impression determines the subsequent accuracy and fit of the final restoration. Therefore, the ultimate search is for the most accurate impression material and the most efficient and least time consuming technique. One of the major debates in implant dentistry has focused on the advantages of the pick-up versus the transfer impression technique. The pick-up technique is widely accepted as the more accurate. However, the conventional transfer technique is simpler and less time consuming. The Hex-Lock-Friction-Fit impression coping (AB Dental Devices) combines the advantages of the transfer impression technique and the pick-up impression technique. In this article we will review the relevant literature, discuss the advantages of this unique implant impression technique, and present some related clinical cases.
Staged Ridge Splitting Technique for Horizontal Expansion in Mandible: A Case Report
Authors: Kheur Mohit , Gokhale Sneha , Sumanth Shivaswamy , Jambekar Shantanu
Published: August 2014

Ridge split procedures are commonly performed for horizontal augmentation of narrow ridges which would otherwise preclude implant placement. A 47-year-old patient with bilaterally edentulous posterior mandibular ridges was treated in the Department of Periodontology and Implantology, M.A. Rangoonwala College of Dental Sciences and Research Centre, employing a “staged ridge split” technique. In this technique, a simple corticotomy at the crestal, apical, and lateral aspects of the buccal cortical plate of the mandible was performed. Following this, a month later, the ridge was expanded and bone graft OssiFi containing biphasic beta-tricalcium phosphate and hydroxyappatite was placed to maintain the gap between the cortices. Thereafter, implants were placed 3 months later. A successful prosthetic rehabilitation was done following a healing phase of 3 months. This approach leads to restoration of function with a predictable outcome and minimal risk of cortical plate fracture during the ridge expansion process.
Platelet-Rich Preparations to Improve Healing. Part II: Platelet Activation and Enrichment, Leukocyte Inclusion, and Other Selection Criteria

Published: August 2014

Multiple platelet-rich preparations have been reported to improve wound and bone healing, such as platelet-rich plasma (PRP) and platelet rich fibrin (PRF). The different methods employed during their preparation are important, as they influence the quality of the product applied to a wound or surgical site. Besides the general protocol for preparing the platelet-rich product (discussed in Part 1 of this review), multiple choices need to be considered during its preparation. For example, activation of the platelets is required for the release and enmeshment of growth factors, but the method of activation may influence the resulting matrix, growth factor availability, and healing. Additionally, some methods enrich leukocytes as well as platelets, but others are designed to be leukocyte-poor. Leukocytes have many important roles in healing and their inclusion in PRP results in increased platelet concentrations. Platelet and growth factor enrichment reported for the different types of platelet-rich preparations are also compared. Generally, TGF-β1 and PDGF levels were higher in preparations that contain leukocytes compared to leukocyte-poor PRP. However, platelet concentration may be the most reliable criterion for comparing different preparations. These and other criteria are described to help guide dental and medical professionals, in large and small practices, in selecting the best procedures for their patients. The healing benefits of platelet-rich preparations along with the low risk and availability of simple preparation procedures should encourage more clinicians to incorporate platelet-rich products in their practice to accelerate healing, reduce adverse events, and improve patient outcomes.

This study aimed to assess and standardize the ELISA and modified ToBI test in vitro methods in order to verify the potency of epsilon toxicoid in comparison with the in vivo TCP method. The following epsilon toxoids were used: NIBSC standard from batches 375/07, 532/08, 551/08, 373/07 and 378/07. These were evaluated using a TCP test, ELISA and ToBI tests. The results indicate that the correlation ratio between the dilutions of standard NIBSC toxicoid and absorbance values of 89.44% obtained with the ELISA method support the use of the curve to evaluate epsilon toxoids. However, it was observed that the absorbance values were similar for all toxoids, thus presenting no significant difference between higher and lower concentration toxoids. For the ToBI test, the correlation ratio of 96.76, obtained in the curve pattern, demonstrates the effectiveness of the curve to be used in the epsilon toxoid evaluation. The correlation ratio between the titration degrees of toxoids obtained through TCP and ToBI tests was higher than 90%. It is concluded that the type of ELISA test used does present discriminative power for toxoids with different concentrations, which does not support the use of this technique for such a purpose.

O desempenho reprodutivo de exemplares selvagens de beijupirá capturados no litoral de Pernambuco e aclimatados ao cativeiro foi avaliado durante 10 meses. Um plantel composto por duas fêmeas (peso de 14 a 16kg) e quatro machos (cerca de 12kg) mantidos em um único tanque de 70t produziu 48,7 milhões de ovos no período de outubro a junho. As fêmeas foram capazes de desovar 21 vezes, com uma frequência média (±DP) de uma desova a cada 11,9 dias (±2,9). Em média, cada desova produziu 2,4 milhões de ovos, com fertilização de 52,4%, o que resultou em aproximadamente 1,0 milhão de larvas por desova. Os resultados demonstram a viabilidade da metodologia empregada na formação do plantel e no manejo de reprodutores e confirmam a relativa facilidade de obtenção de desovas espontâneas do beijupirá em cativeiro. Também foi confirmado que o período reprodutivo dessa espécie em cativeiro se estende além do observado na natureza. Este é o primeiro relato sobre o desempenho reprodutivo do beijupirá em cativeiro no Brasil.

Objetivou-se, neste trabalho, determinar a melhor relação entre proteína e carboidrato na dieta do híbrido carnívoro Pseudoplatystoma fasciatume Leiarius marmoratus. Utilizou-se um sistema fechado de recirculação de água, composto de 12 caixas de 500L e biofiltro. Foram utilizados 144 juvenis (12/caixa) com peso médio inicial de 12,63±2,52g e comprimento total de 12,34±2,06cm durante 50 dias. Os peixes receberam quatro dietas contendo diferentes relações proteína:carboidrato (1,24; 0,84; 0,56 e 0,33). A relação proteína:carboidrato influenciou o desempenho e os parâmetros metabólicos dos animais. A melhor relação proteína:carboidrato para o desempenho foi 0,84. Os resultados metabólicos demonstraram mobilização de nutrientes para manutenção de glicemia e do crescimento. A relação proteína:carboidrato de 0,84 foi a mais indicada para o híbrido.

The bromatological composition and in vitro dry matter digestibility of millet cultivars were assessed for different nitrogen doses and two sowing seasons in the Ceres municipality of Goiás state, Brazil. The treatments consisted of three millet cultivars (ADR-7010, ADR-500 and BRS-1501), four nitrogen (N) doses (0, 50, 100 and 200kg ha-1 of N) and two sowing seasons. Three replicates and a randomised block design with a 3 x 4 x 2 factorial scheme were used. Two cuttings were performed in each season when plants reached an average height of 0.70 cm. No significant interactions were observed between or among cultivars for N doses and dry matter (DM), crude protein (CP), neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents. The DM, CP, NDF and ADF contents were significantly different between N doses. The DM and CP contents increased as the N dose increased to 100kg ha-1. The maximum DM and CP contents were 11.14 and 22.53%, respectively. The NDF and ADF contents were higher in the control treatment (60.11 and 30.01%, respectively). In addition, the lowest ADF and NDF concentrations occurred at an N dose of 50kg ha-1(56.33 and 30.23%, respectively). The DM contents were higher for the February sowing, with an average of 10.59%. The highest CP and ADF contents were found for the December sowing (22.46 and 31.58%, respectively). No significant differences were found for millet cultivars, N doses or sowing seasons. A significant interaction was found between sowing season and millet cultivar. The BRS-1501 cultivar had a higher in vitro dry matter digestibility in the December/2010 sowing (73.88%).

Acidentes por escorpião constituem problema de saúde pública em Belo Horizonte. Realizou-se um estudo epidemiológico observacional retrospectivo para analisar a frequência e distribuição espacial dos acidentes escorpiônicos em Belo Horizonte, entre 2005 e 2009, e associá-las às categorias de risco classificadas pelo Índice de Vulnerabilidade à Saúde (IVS), um índice socioeconômico regional composto. Foram utilizados dados de notificação do Sistema Nacional de Agravos de Notificação (SINAN) e Sistema de Vigilância Epidemiológica (SISVE), referentes aos anos de 2008 e 2009. Para o período de 2005 a 2007, foi necessário o resgate de dados das fichas clínicas do Hospital João XXIII (HPSJXXIII) correspondentes às variáveis encontradas no SINAN e SISVE, uma vez que os mesmos não estavam digitalizados nos referidos sistemas de informação. Para georreferenciamento e análise espacial, foi utilizada a base geográfica EndGeo, o aplicativo de mapeamento MapInfo versão 10.0 e os programas Hotspot Detective e SatScan. Entre 2005 e 2009, ocorreram em Belo Horizonte 2.769 casos de acidentes por escorpião, o que representa uma incidência média de 22,4 casos por 100.000 habitantes. Do total de casos, 1.924 (69,5%) foram georreferenciados e houve predomínio de incidência em dois Distritos Sanitários (DS), com grande concentração de casos nas regiões de cemitérios do município. Foram detectados dois "clusters" no período, sendo um em 2005, nos DS Noroeste e Oeste, e outro entre 2006 e 2007, nos DS Noroeste e Nordeste. Não houve associação entre as áreas de maior incidência de escorpionismo e as áreas de maior risco à saúde classificadas pelo IVS. Com base nos resultados, conclui-se que há necessidade de melhorias no processo de notificação do agravo e que o mapeamento dos casos é uma ferramenta relevante capaz de embasar o direcionamento das ações educativas de controle para as áreas prioritárias de Belo Horizonte.

Objetivo caracterizar e comparar a audição de funcionários de um hospital público expostos a níveis de ruído ocupacional máximos superiores e inferiores a 85dB(A). Métodos trata-se de um estudo clínico, com 39 funcionários de um hospital público, divididos de acordo com o nível de exposição ao ruído: 20 indivíduos sob exposição máxima superior a 85dB(A) (Grupo 1) e 19 indivíduos sob exposição máxima inferior a 85dB(A) (Grupo 2). Foi realizada avaliação audiológica básica e emissões otoacústicas evocadas por estímulo transiente e produto de distorção. Resultados ambos os grupos apresentaram limiares de audibilidade normais. Contudo, observou-se ausência de respostas em 87,5% no Grupo 1 e 60,5% no Grupo 2 no teste de emissões otoacústicas evocadas por estímulo transiente, com diferença estatística. O Grupo 1 mostrou menor amplitude de respostas também às emissões otoacústicas produto de distorção, sendo a frequência de 6kHz a única alterada em ambos os grupos. Conclusão os níveis de pressão sonora e o tempo de exposição não influenciam os limiares auditivos tonais. As emissões otoacústicas mostraram-se mais alteradas quanto maior o nível de pressão sonora e tempo de exposição.

Objetivo verificar o comportamento auditivo de resolução temporal em mulheres com Migrânea Menstrual. Métodos participaram 40 mulheres, na faixa etária de 18 a 31 anos, das quais 20 apresentaram migrânea menstrual (grupo estudo) e 20 não apresentaram (grupo controle). Todas foram submetidas a procedimentos que fazem parte da rotina audiológica para caracterizar a audição periférica e excluir pessoas com perdas auditivas. Ainda, foram submetidas a um questionário elaborado pela pesquisadora e a uma aplicação do teste Gap in noise. Os procedimentos foram realizados na fase subfolicular precoce e na subfase lútea tardia para voluntárias que não faziam uso de anticoncepcional, uma vez que nestas fases a taxa de hormônios femininos esta mais elevada e semelhante daquelas que faziam uso de anticoncepcional. Resultados os valores dos limiares de gap e porcentagem de acertos da orelha esquerda, no grupo de estudo foram significantemente e estatisticamente diferentes em relação ao grupo controle. Em relação à orelha direita, os achados foram similares entre os grupos. Conclusão a resolução temporal em mulheres com migrânea menstrual, medida a um segmento de ruído, na orelha direita foi semelhante à das mulheres sem essa queixa, já na orelha esquerda os grupos se diferenciaram e os com migrânea obtiveram os piores limiares.
