Antonovsky Bütünlük Duygusu Ölçeği ve Hemşirelik Araştırmalarında Kullanımının Sistematik İncelemesi: Ruh Sağlığı ve Psikiyatri Hemşireliği Açısından Anlamlar

Text in English and TurkishObjectives: Antonovsky’s salugenetic model focuses on factors that promote health and well-being. The objectives of this paper were to review the existing research literature related to Antonovsky’s Sense of Coherence Scale (SOC) and establish implications for psychiatric and mental health nurses. Methods: Electronic databases were searched with selected studies compared for sample, sample size, study designs and basic results. Cross-sectional studies were reviewed for correlations between personality traits, stress, burnout, disease-scales, job satisfaction and the SOC scale, with Intervention studies used to establish the impact of training on the SOC. Results: The review discovered serious methodological difficulties, including interpretations of Antonovsky’s philosophical values and the apparent use of the SOC scales as a measure of disease absence. Conclusion: The review was able to draw important conclusions for psychiatric and mental health nurses (PMHNs) related to stress, burnout, dealing with psychiatric emergencies and the selection of new recruits to the profession.peer-reviewe

EFFECT OF RISK PERSPECTIVE ON FERTILIZER CHOICE BY SHARECROPPERS

Peanut and corn are two major crops in the tri-state area of the Southeast US, an area encompassing North Florida, Southwest Georgia, and Southeast Alabama. Sharecroppers in this region apply higher amount of input in crop production than the average farmers. We analyzed the behavior of sharecroppers in this region with regard to their fertilizer application decisions. Two hypotheses were formulated and tested based on sharecroppers' fertilizer application decisions: one assuming that sharecroppers are risk averse farmers and the other assuming that sharecroppers are regret minimizers. Our results show that a sharecropper uses different fertilizer treatments when minimizing risk depending on risk perspective and desired income. Sharecroppers who apply more fertilizer to obtain a desired level of income are regret minimizers where as sharecroppers who apply relatively low fertilizer are risk minimizer. At the same desired level of income, a regret minimizer farmer would apply a higher amount of fertilizer than the risk averse farmers. Our analysis revealed that sharecroppers in the Southeast US are regret minimizers as they apply a higher amount of fertilizer than an average farmer on the major crops grown in the region. The result of this study also confirms the result of a previous study in the region which reported that sharecroppers in the region are over capitalized and apply more fertilizer than average farmers.Southeast U.S., Sharecroppers, Regret minimizer, Risk averse, Peanut-Corn rotation, Farm Management, Risk and Uncertainty,

Diversity and repertoire of IgW and IgM VH families in the newborn nurse shark

BACKGROUND: Adult cartilaginous fish express three immunoglobulin (Ig) isotypes, IgM, IgNAR and IgW. Newborn nurse sharks, Ginglymostoma cirratum, produce 19S (multimeric) IgM and monomeric/dimeric IgM(1gj), a germline-joined, IgM-related VH, and very low amounts of 7S (monomeric) IgM and IgNAR proteins. Newborn IgNAR VH mRNAs are diverse in the complementarity-determining region 3 (CDR3) with non-templated nucleotide (N-region) addition, which suggests that, unlike in many other vertebrates, terminal deoxynucleotidyl transferase (TdT) expressed at birth is functional. IgW is present in the lungfish, a bony fish sharing a common ancestor with sharks 460 million years ago, implying that the IgW VH family is as old as the IgM VH family. This nurse shark study examined the IgM and IgW VH repertoire from birth through adult life, and analyzed the phylogenetic relationships of these gene families. RESULTS: IgM and IgW VH cDNA clones isolated from newborn nurse shark primary and secondary lymphoid tissues had highly diverse and unique CDR3 with N-region addition and VDJ gene rearrangement, implicating functional TdT and RAG gene activity. Despite the clear presence of N-region additions, newborn CDR3 were significantly shorter than those of adults. The IgM clones are all included in a conventional VH family that can be classified into five discrete groups, none of which is orthologous to IgM VH genes in other elasmobranchs. In addition, a novel divergent VH family was orthologous to a published monotypic VH horn shark family. IgW VH genes have diverged sufficiently to form three families. IgM and IgW VH serine codons using the potential somatic hypermutation hotspot sequence occur mainly in VH framework 1 (FR1) and CDR1. Phylogenetic analysis of cartilaginous fish and lungfish IgM and IgW demonstrated they form two major ancient gene groups; furthermore, these VH genes generally diversify (duplicate and diverge) within a species. CONCLUSION: As in ratfish, sandbar and horn sharks, most nurse shark IgM VH genes are from one family with multiple, heterogeneous loci. Their IgW VH genes have diversified, forming at least three families. The neonatal shark Ig VH CDR3 repertoire, diversified via N-region addition, is shorter than the adult VDJ junction, suggesting one means of postnatal repertoire diversification is expression of longer CDR3 junctions

Ferromagnetic and multiferroic interfaces in granular perovskite composite xLa0.5Sr0.5CoO3-(1-x)BiFeO3

of ferromagnetic La0.5Sr0.5CoO3 (LSCO) and multiferroic BiFeO3 (BFO) were synthesized by spray pyrolysis method. Different compositions of multiferroic xLSCO-(1-x)BFO composites were synthesized at 800 °C for 2 h. Scanning electron microscopy and energy dispersive spectroscopy elemental mapping were performed to study the morphology of composites. Ferri/ferromagnetic responses above TC (LSCO) are observed, which are associated with the interfaces LSCO/BFO. This interface presents a different behavior compared to the original perovskites, and the magnitude of the magnetization depends on x. Electrical DC conductivity as a function of temperature for LSCO nanopowder (x = 1) presents a different behavior than that reported in bulk material. For x = 1 and 0.9, the model by Glazman and Matveev [Zh. Eksp. Teor. Fiz. 94, 332 (1988)] is proposed to describe the electrical conductivity. On the other hand, x = 0, 0.1, and 0.5 present a variable range hopping behavior. Complex impedance spectroscopy as a function of frequency indicates a pure resistive behavior for x ≥ 0.5 compositions, while a complex resistive-capacitive behavior is observed for low x values (0, 0.1). In these samples, low values of magnetoelectric coupling were measured with an AC lock-in technique.Fil: Lohr, Javier Hernán. Comisión Nacional de Energía Atómica.

Behavioral strategies during incubation influence nest and female survival of Wild Turkeys

Females must balance physiological and behavioral demands of producing offspring with associated expenditures, such as resource acquisition and predator avoidance. Nest success is an important parameter underlying avian population dynamics. Galliforms are particularly susceptible to low nest success due to exposure of ground nests to multiple predator guilds, lengthy incubation periods, and substantive reliance on crypsis for survival. Hence, it is plausible that nesting individuals prioritize productivity and survival differently, resulting in a gradient of reproductive strategies. Fine-scale movement patterns during incubation are not well documented in ground-nesting birds, and the influence of reproductive movements on survival is largely unknown. Using GPS data collected from female wild turkeys (n = 278) across the southeastern United States, we evaluated the influence of incubation recess behaviors on trade-offs between nest and female survival. We quantified daily recess behaviors including recess duration, recess frequency, total distance traveled, and incubation range size for each nest attempt as well as covariates for nest concealment, nest attempt, and nest age. Of 374 nests, 91 (24%) hatched and 39 (14%) females were depredated during incubation. Average nest survival during the incubation period was 0.19, whereas average female survival was 0.78. On average, females took 1.6 daily unique recesses (SD = 1.2), spent 2.1 hr off the nest each day (SD = 1.8), and traveled 357.6 m during recesses (SD = 396.6). Average nest concealment was 92.5 cm (SD = 47). We found that females who took longer recess bouts had higher individual survival, but had increased nest loss. Females who recessed more frequently had lower individual survival. Our findings suggest behavioral decisions made during incubation represent life-history trade-offs between predation risk and reproductive success on an unpredictable landscape

Prototype chicken galectins revisited: characterization of a third protein with distinctive hydrodynamic behaviour and expression pattern in organs of adult animals

Prototype galectins are versatile modulators of cell adhesion and growth via their reactivity to certain carbohydrate and protein ligands. These functions and the galectins' marked developmental regulation explain their attractiveness as models to dissect divergent evolution after gene duplication. Only two members have so far been assumed to constitute this group in chicken, namely the embryonic muscle/liver form {C-16 or CLL-I [16 kDa; chicken lactose lectin, later named CG-16 (chicken galectin-16)]} and the embryonic skin/intestine form (CLL-II or C-14; later named CG-14). In the present study, we report on the cloning and expression of a third prototype CG. It has deceptively similar electrophoretic mobility compared with recombinant C-14, the protein first isolated from embryonic skin, and turned out to be identical with the intestinal protein. Hydrodynamic properties unusual for a homodimeric galectin and characteristic traits in the proximal promoter region set it apart from the two already known CGs. Their structural vicinity to galectin-1 prompts their classification as CG-1A (CG-16)/CG-1B (CG-14), whereas sequence similarity to mammalian galectin-2 gives reason to refer to the intestinal protein as CG-2. The expression profiling by immunohistochemistry with specific antibodies discerned non-overlapping expression patterns for the three CGs in several organs of adult animals. Overall, the results reveal a network of three prototype galectins in chicken. © The Authors

Toward Comprehensive Analysis of the Galectin Network in Chicken: Unique Diversity of Galectin-3 and Comparison of its Localization Profile in Organs of Adult Animals to the Other Four Members of this Lectin Family

18 pags, 11 figs, 2 tabs. -- Additional Supporting Information may be found in the online version of this articleCharacterization of all members of a gene family established by gene divergence is essential to delineate distinct or overlapping expression profiles and functionalities. Their activity as potent modulators of diverse physiological processes directs interest to galectins (endogenous lectins with β-sandwich fold binding β-galactosides and peptide motifs), warranting their study with the long-term aim of a comprehensive analysis. The comparatively low level of complexity of the galectin network in chicken with five members explains the choice of this organism as model. Previously, the three proto-type chicken galectins CG-1A, CG-1B, and CG-2 as well as the tandem-repeat-type CG-8 had been analyzed. Our study fills the remaining gap to determine gene structure, protein characteristics and expression profile of the fifth protein, that is, chimera-type chicken galectin-3 (CG-3). Its gene has a unique potential to generate variants: mRNA production stems from two promoters, alternative splicing of the form from the second transcription start point (tsp) can generate three mRNAs. The protein with functional phosphorylation sites in the N-terminus generated by transcription from the first tsp (tsp1CG-3) is the predominant CG-3 type present in adult tissues. Binding assays with neoglycoproteins and cultured cells disclose marked similarity to properties of human galectin-3. The expression and localization profiles as well as proximal promoter regions have characteristic features distinct from the other four CGs. This information on CG-3 completes the description of the panel of CGs, hereby setting the stage for detailed comparative analysis of the entire CG family, e.g., in embryogenesis. © 2011 Wiley-Liss, Inc.Spanish Ministry of Science and Innovation Grant number: BFU2009-10052; Grant sponsor: CIBER of Respiratory Diseases (CIBERES) (ISCII

大脳由来と小脳由来の初代培養アストロサイトは、アポトーシスに関連する細胞外ナトリウム感受性が異なる

Central pontine myelinolysis is one of the idiopathic or iatrogenic brain dysfunction, and the most common cause is excessively rapid correction of chronic hyponatraemia. While myelin disruption is the main pathology, as the diagnostic name indicates, a previous study has reported that astrocyte death precedes the destruction of the myelin sheath after the rapid correction of chronic low Na+ levels, and interestingly, certain brain regions (cerebral cortex, hippocampus, etc.) are specifically damaged but not cerebellum. Here, using primary astrocyte cultures derived from rat cerebral cortex and cerebellum, we examined how extracellular Na+ alterations affect astrocyte death and whether the response is different between the two populations of astrocytes. Twice the amount of extracellular [Na+] and voltage-gated Na+ channel opening induced substantial apoptosis in both populations of astrocytes, while, in contrast, one half [Na+] prevented apoptosis in cerebellar astrocytes, in which the Na+–Ca2+ exchanger, NCX2, was highly expressed but not in cerebral astrocytes. Strikingly, the rapid correction of chronic one half [Na+] exposure significantly increased apoptosis in cerebellar astrocytes but not in cerebral astrocytes. These results indicate that extracellular [Na+] affects astrocyte apoptosis, and the response to alterations in [Na+] is dependent on the brain region from which the astrocyte is derived.博士（医学）・乙第1346号・平成26年12月3日Copyright © 2014 John Wiley & Sons, Ltd

On the performances of different IMRT treatment planning systems for selected paediatric cases

BACKGROUND: To evaluate the performance of seven different TPS (Treatment Planning Systems: Corvus, Eclipse, Hyperion, KonRad, Oncentra Masterplan, Pinnacle and PrecisePLAN) when intensity modulated (IMRT) plans are designed for paediatric tumours. METHODS: Datasets (CT images and volumes of interest) of four patients were used to design IMRT plans. The tumour types were: one extraosseous, intrathoracic Ewing Sarcoma; one mediastinal Rhabdomyosarcoma; one metastatic Rhabdomyosarcoma of the anus; one Wilm's tumour of the left kidney with multiple liver metastases. Prescribed doses ranged from 18 to 54.4 Gy. To minimise variability, the same beam geometry and clinical goals were imposed on all systems for every patient. Results were analysed in terms of dose distributions and dose volume histograms. RESULTS: For all patients, IMRT plans lead to acceptable treatments in terms of conformal avoidance since most of the dose objectives for Organs At Risk (OARs) were met, and the Conformity Index (averaged over all TPS and patients) ranged from 1.14 to 1.58 on primary target volumes and from 1.07 to 1.37 on boost volumes. The healthy tissue involvement was measured in terms of several parameters, and the average mean dose ranged from 4.6 to 13.7 Gy. A global scoring method was developed to evaluate plans according to their degree of success in meeting dose objectives (lower scores are better than higher ones). For OARs the range of scores was between 0.75 ± 0.15 (Eclipse) to 0.92 ± 0.18 (Pinnacle(3 )with physical optimisation). For target volumes, the score ranged from 0.05 ± 0.05 (Pinnacle(3 )with physical optimisation) to 0.16 ± 0.07 (Corvus). CONCLUSION: A set of complex paediatric cases presented a variety of individual treatment planning challenges. Despite the large spread of results, inverse planning systems offer promising results for IMRT delivery, hence widening the treatment strategies for this very sensitive class of patients
