New Fisheries-related data from the Mediterranean Sea (October 2015)

In this third Collective Article, with fisheries-related data from the Mediterranean Sea, we present the historical length distribution of Lophius budegassa in the catch of commercial trawlers in the Greek seas; length-weight and length-length relationships of five flatfish species (Lepidorhombus boscii, L. whiffiagonis, Platichthys flesus, Pegusa lascaris and Solea solea) from different coastal areas of Turkey (Black Sea and Eastern Mediterranean Sea); growth of settled Polyprion americanus and length-weight relationships of this species and of Deltentosteus quadrimaculatus, Capros aper and three commercially important groupers in the Eastern Mediterranean Sea; the age, growth and mortality of Zosterisessor ophiocephalus in the Eastern Adriatic Sea; the length-weight relationship and condition factor of Atherina boyeri in a Central Mediterranean semi-isolated lagoon, and also the length-weight and length-length relationships of three Alburnus species from different inland waters in Turkey

A modern network approach to revisiting the positive and negative affective schedule (PANAS) construct validity

Introduction: The factor structure of the Positive and Negative Affective Schedule (PANAS) is still a topic of debate. There are several reasons why using Exploratory Graph Analysis (EGA) for scale validation is advantageous and can help understand and resolve conflicting results in the factor analytic literature. Objective: The main objective of the present study was to advance the knowledge regarding the factor structure underlying the PANAS scores by utilizing the different functionalities of the EGA method. EGA was used to (1) estimate the dimensionality of the PANAS scores, (2) establish the stability of the dimensionality estimate and of the item assignments into the dimensions, and (3) assess the impact of potential redundancies across item pairs on the dimensionality and structure of the PANAS scores. Method: This assessment was carried out across two studies that included two large samples of participants. Results and Conclusion: In sum, the results are consistent with a two-factor oblique structure.Fil: Flores Kanter, Pablo Ezequiel. Universidad Empresarial Siglo XXI; Argentina.

Factor structure of the de Jong Gierveld loneliness scale in Spanish elderly adults

La soledad es un importante componente en la medición del bienestar subjetivo de las personas mayores. El instrumento más influyente en Europa es la escala de soledad de 11 ítems de De Jong Gierveld (DJGLS; de Jong Gierveld y Kamphuis, 1985). El objetivo de esta investigación era examinar la estructura interna de la versión española de la DJGLS. La muestra estaba compuesta por 328 personas mayores (M = 75.53, Rango = 60-99 años) no institucionalizadas. Los análisis factoriales mostraron que la escala era esencialmente unidimensional (RMR = .088, AGFI = .97). La fiabilidad fue de .91. No se encontraron razones sustantivas ni estadísticas para considerar la existencia de un segundo factor. Nuestros resultados revelaron algunos problemas de los ítems para medir los aspectos sociales y emocionales de la soledad como factores distintos. Se resalta la necesidad de mejorar la escala y de tener en cuenta las diferencias entre las culturas colectivistas e individualistas en el uso de los instrumentos que miden el bienestar.Loneliness is an important component in the measurement of subjective well-being of elderly adults.

The aim of this study was to examine, throughout factorial techniques, the internal structure the Spanish version of the DJGLS. Data were gathered from 328 community-dwelling elderly adults (M = 75.53, Range: 60-99 years). The factor analysis techniques revealed that the scale was essentially unidimensional (RMR = .088, AGFI = .970, NFI = .966). Reliability was .91. Neither substantive nor statistical reasons were found to consider the existence of a second factor. Our findings also revealed some psychometric problems in the measurement of the social and emotional aspects of loneliness. Emphasis is placed on the need to improve the scale and bear in mind the differences between collectivist and individualist cultures in the use of scales measuring well-being

Efficacy of glutathione mesotherapy in burns: an experimental study

Background: Thermal burns are the leading cause of trauma worldwide. Currently, no consensus on optimal treatment of deep partial-thickness (second-degree) burns has emerged, as reflected by the wide variability in available wound-care materials. The relative efficacies of products used for treatment of partial-thickness thermal burns remain unclear. Mesotherapy features intradermal administration of various agents, depending on burn location. In the present experimental study, we explored the efficacy of mesotherapy used to treat partial-thickness thermal burns in 50 male Wistar rats divided into five groups of equal number. No procedure was performed after infliction of thermal burns in control group (Group 1). Mesotherapy was applied with physiological saline in sham group (Group 2), glutathione, taurine, and l-carnitine were separately applied in Group 3, Group 4, and Group 5, respectively. Materials and methods: Mesotherapeutic agents were injected intradermally into the reticular layer of the dermis using the point technique. The first course of mesotherapy was given within the first 2 h after infliction of thermal burns, and therapy was continued to day 10. On day 22, unhealed thermal burn areas were measured prior to sacrifice, and biopsies covering the total areas of burns were performed to allow of pathological evaluation. Results: Group 3 (the glutathione group) showed the best extent of healing, followed by Group 4 (the taurine group) and Group 5 (the l-carnitine group). The healed thermal burn areas in these groups were significantly greater than those in the control and sham groups (P = 0.001). All of healing, acute and chronic inflammation, the amount of granulation tissue, the level of fibroblast maturation, the amount of collagen, the extent of re-epithelization and neovascularization, and ulcer depth were scored upon pathological examination of tissue cross-sections. The best outcomes were evident in the glutathione group, with statistical significance. Although wound healing in the l-carnitine and taurine groups was better than in the control and sham groups, the differences were not statistically significant. Conclusion: Thus, glutathione mesotherapy was effective when used to treat partial-thickness thermal burns and may be a useful treatment option for various human burns. © 2015, Springer-Verlag Berlin Heidelberg
