Crocidura cossyrensis Contoli, 1989 (Mammalia, Soricidae): karyotype, biochemical genetics and hybridization experiments. - The shrew Crocidura cossyrensis Contoli, 1989 from Pantelleria (I), a Mediterranean island 100 km south of Sicily and 70 km west from Tunisia, was investigated in order to understand its origin and its relationship with C. russula from Tunisia, Morocco and Switzerland. With the exception of a single heterozygote centric fusion, C. cossyrensis had a karyotype identical with that of C russula from Tunisia (2N = 42, NF = 70 to 72), but it differed from C russula from Morocco and Switzerland (2N = 42, NF = 60). The former have 5-6 pairs of chromosomes with small arms that are acrocentric in the latter. Genetic comparisons with allozyme data revealed small genetic distance (0.04) between C cossyrensis and C russula from Tunisia. In contrast, this eastern clade (Tunisia and Pantelleria) is separated from the western clade (Switzerland and Morocco) by a genetic distance of 0.14. A hybridization experiment between shrews from Pantelleria and Switzerland lead rapidly to an F1 generation. From 12 F1 hybrids that were backcrossed, females reproduced normally, but none of the males did so. Concluding from the results, C. cossyrensis from Pantelleria and C. russula cf. agilis from Tunisia belong to the same taxon that may have reached the differentiation of a biological species within the C. russula group. More geographic samples are needed to determine the definitive taxonomic positions of these shrews.

How long induced moods last is a critical question for mood research but has been only poorly addressed. In particular, physiological parameters have been rarely included to assess the effectiveness of mood induction procedures. Adopting a dimensional model of mood, we investigated the persistence of four different moods (positive higharousal, positive low-arousal, negative high-arousal, negative lowarousal) induced by four film clips ("sport", "nature", "torture", "slum") during a 9-minute computer task. We measured subjective mood state (valence and arousal), respiration, skin conductance level (SCL), heart rate, and corrugator activity in 76 subjects. Viewing of the selected film clips induced the expected effects both subjectively and physiologically. Corrugator activity was higher at the end of the negative clips than the positive clips, and ventilation and SCL were higher for the arousing clips than for the less arousing clips. People who watched the negative clips still reported more negative valence after the computer task and also showed more facial frowning (cf. figure) and lower SCL during the task than people who watched the positive clips. No arousal effects persisted throughout the task. The results suggest that induced changes in the valence dimension of moods are maintained throughout an intervening task and are physiologically best reflected by corrugator activity and SCL, whereas induced changes in the arousal dimension dissipate quickly. The findings of this study enrich, first, our knowledge concerning the relationships between subjective feelings and their physiological substrate. Second, they inform us about the effectiveness of film clips as a mood induction instrument. Third and most important, they suggest that induced changes in valence last longer than induced changes in arousal. High-arousal moods can last for an extended period of time in daily life, but they seem to be short-lived when induced in the lab. An important methodological consequence is that investigating the effect of the arousal dimension of a person's mood induced in the lab may be only possible when the subsequent task is relatively short. Finally, the findings show which physiological measures may be useful in tracking mood states.

The book of Joshua is in the very center of the recent discussion about the existence of a coherent deuteronomistic redaction in Deut to 2 Kings during the exilic period. This article analyses the beginning (Josh 1.1-9) and the end (Josh 23 and 24) of Josh. Josh 1.1-2,5-7 and chapter 23 belong to the dtr edition. Josh 23 was followed by Judg 2.6ff. During the Persian period, Deuteronomists and priests intended to publish one Law for the whole community. There was probably a discussion whether the Torah should be a Penta- or a Hexateuch. This discussion may explain such a text as Josh 24 which clearly tries to construct an Hexateuch (cf. also Gen. 50.25: Exod 13.19; Josh 24.32). But since the Torah is about foundations, the main theological trends agreed to have its end with the death of Moses.

Core-samples from wells and an outcrop located on the Voronesh Anticline in the southeastern part of the Russian Platform contain Late Cretaceous radiolaria. 83 species are described and illustrated (SEM and transmitted light images) from Santonian-early Campanian deposits, and two assemblages are distinguished. The older assemblage with Alievium gallowayi, Archaeospongoprunum bipartitum, Archaeospongoprunum. cf. A. salumi as well as other less age-diagnostic taxa, is interpreted as Santonian correlative with the Euchitonia santonica-Alievium gallowayi Assemblage Zone of the Moscow Basin (Vishnevskaya 1993). The younger assemblage, of Santonian - early Campanian age, contains Patulibracchium cf. P. davisi, Crucella irwini, Cryptamphorella sphaerica, Praeconocaryomma californiensis, Dictyomitra lamellicostata among other species and is correlative with the Orbiculiforma quadrata-Lithostrobus rostovtsevi Assemblage Zone of the Moscow Basin. In terms of inter-regional faunal comparisons, both of the Voronesh Anticline radiolarian assemblages demonstrate relatively close affinities to coeval rocks from the Volga River region, but less similarity to the assemblages from the Moscow Basin. Only a few of the common endemic species of Siberian assemblages occur in our samples. On an inter-regional level, the radiolarian assemblages described herein have similarities with assemblages reported from Japan and California. Index-species characteristic for the Santonian-Campanian radiolarian biozonations of the Atlantic and Pacific Oceans are not found in our collection. However, the presence of many cosmopolitan species known from the European Platform, Japan and California suggests a marine connection between the Voronesh Anticline region, the western Atlantic and eastern Tethys during Santonian-Early Campanian time.

BACKGROUND: Newborn screening (NBS) for Cystic Fibrosis (CF) has been introduced in many countries, but there is no ideal protocol suitable for all countries. This retrospective study was conducted to evaluate whether the planned two step CF NBS with immunoreactive trypsinogen (IRT) and 7 CFTR mutations would have detected all clinically diagnosed children with CF in Switzerland. METHODS: IRT was measured using AutoDELFIA Neonatal IRT-Kit in stored NBS cards. RESULTS: Between 2006 and 2009, 66 children with CF were reported, 4 of which were excluded for various reasons (born in another country, NBS at 6 months, no informed consent). 98% (61/62) had significantly higher IRT compared to matched control group. There was one false negative IRT result in an asymptomatic child with atypical CF (normal pancreatic function and sweat test). CONCLUSIONS: All children but one with atypical CF would have been detected with the planned two step protocol.

Cystic fibrosis (CF) patients often present with malnutrition which may partly be due to increased resting energy expenditure (REE) secondary to inflammation. Both REE and tumour necrosis factor-alpha (TNF-alpha), as other markers of inflammation, are elevated during respiratory exacerbations and decrease after antibiotic treatment. However, the effect of antibiotic therapy on REE and inflammation in patients without respiratory exacerbation is not known. The aim of our study was to determine the effect of such an elective antibiotic therapy on REE, TNF-alpha, and other serum markers of inflammation. Twelve CF patients 5F/7M, age 15.9 +/- 6.1 years, weight for height ratio 89 +/- 8% without clinically obvious exacerbation and treated by intravenous antibiotics were studied. Both before (D0) and after (D14) treatment, pulmonary function tests were performed. REE was measured by indirect calorimetry and blood taken to measure inflammation parameters. Body weight increased by 1.1 kg from D0 to D14 (P < 0.001), composed of 0.3 kg fat mass and 0.8 kg fat-free mass (FFM). The forced expiratory volume at 1 s increased from 43 +/- 15% of predicted at D0 to 51 +/- 15% of predicted at D14 (P < 0.01). Mean REE was 41.1 +/- 7.6 kcal/kg FFM per day at D0 and did not change significantly at D14 (40.6 +/- 8.5 kcal/kg FFM per day). Serum markers of inflammation decreased from D0 to D14: C-reactive protein 17 +/- 17 mg/l to 4 +/- 7 mg/l (P < 0.05), elastase 62 +/- 29 microg/l to 45 +/- 18 microg/l (P < 0.02), orosomucoid acid 1.25 +/- 0.11 g/l to 0.80 +/- 0.15 g/l (P < 0.001), and TNF-alpha 37 +/- 14 pg/ml to 29 +/- 6 pg/ml (P = 0.05). Individual values showed a correlation between changes in REE and in TNF-alpha (P < 0.02). The contribution of inflammation to energy expenditure is possible but appears to be minimal in cystic fibrosis patients treated by antibiotics on a regular basis in the absence of clinically obvious exacerbation.

RATIONALE AND OBJECTIVES: The purpose of this study was the investigation of the impact of real-time adaptive motion correction on image quality in navigator-gated, free-breathing, double-oblique three-dimensional (3D) submillimeter right coronary magnetic resonance angiography (MRA). MATERIALS AND METHODS: Free-breathing 3D right coronary MRA with real-time navigator technology was performed in 10 healthy adult subjects with an in-plane spatial resolution of 700 x 700 microm. Identical double-oblique coronary MR-angiograms were performed with navigator gating alone and combined navigator gating and real-time adaptive motion correction. Quantitative objective parameters of contrast-to-noise ratio (CNR) and vessel sharpness and subjective image quality scores were compared. RESULTS: Superior vessel sharpness, increased CNR, and superior image quality scores were found with combined navigator gating and real-time adaptive motion correction (vs. navigator gating alone; P < 0.01 for all comparisons). CONCLUSION: Real-time adaptive motion correction objectively and subjectively improves image quality in 3D navigator-gated free-breathing double-oblique submillimeter right coronary MRA.

A utilização de resíduos orgânicos de origem animal na adubação das culturas demanda informações sobre a dinâmica de decomposição e mineralização de nutrientes neles contidos. Este trabalho objetivou avaliar a decomposição e a liberação de N, P e K dos resíduos orgânicos esterco bovino e cama de frango isolados ou misturados, em Argissolo Vermelho-Amarelo, da região de Tabuleiros Costeiros paraibanos. O experimento foi conduzido em delineamento experimental de blocos casualizados, utilizando-se o método das sacolas de decomposição (litterbag), com os tratamentos arranjados em esquema fatorial 3 × 2 × 6, referentes a três resíduos orgânicos: esterco bovino (EB), cama de frango (CF) e a mistura desses resíduos na proporção de 1:1, denominada de esterco misto (EM); duas camadas de incorporação (0-10 e 10-20 cm); e seis períodos de avaliação (0, 30, 90, 150, 210 e 270 dias após a aplicação - DAA) com três repetições. Os resultados revelaram que a profundidade de incorporação não influenciou a decomposição dos resíduos EB e EM, que essa foi mais rápida na CF (0,0035 g dia-1), mais lenta no EB (0,0010 g dia-1) e ocorreu numa velocidade intermediária no EM (0,0020 g dia-1). Houve liberação mais rápida de N no EM (0,0011 g dia-1), de P no EB (0,0040 g dia-1) e de K na CF (0,0025 g dia-1), com tendência de aumento na liberação de N na CF e de P em todos os resíduos com a incorporação desses na camada de 10-20 cm. Após 270 DAP, estimou-se que a liberação de nutrientes pelos resíduos EB, CF e EM, em relação ao teor inicial, foi de 5,0; 15,0; e 28,0 %, para N; 80,0; 68,0; e 47,0 %, para P; e 20,0; 53,0; e 32,0 %, para K. Em valores absolutos, esses percentuais representaram, respectivamente, 19,0; 103,5; e 149,5 kg ha-1 de N; 28,0; 18,0; e 15,0 kg ha-1 de P; e 75,0; 493,0; e 209,0 kg ha-1 de K. Os resíduos orgânicos se evidenciaram fontes inadequadas para suprir isoladamente a demanda nutricional de culturas de ciclo curto nesses solos.

Because of their role in limiting gene flow, geographical barriers like mountains or seas often coincide with intraspecific genetic discontinuities. Although the Strait of Gibraltar represents such a potential barrier for both plants and animals, few studies have been conducted on its impact on gene flow. Here we test this effect on a bat species (Myotis myotis) which is apparently distributed on both sides of the strait. Six colonies of 20 Myotis myotis each were sampled in southern Spain and northern Morocco along a linear transect of 1350 km. Results based on six nuclear microsatellite loci reveal no significant population structure within regions, but a complete isolation between bats sampled on each side of the strait. Variability at 600 bp of a mitochondrial gene (cytochrome b) confirms the existence of two genetically distinct and perfectly segregating clades, which diverged several million years ago. Despite the narrowness of the Gibraltar Strait (14 km), these molecular data suggest that neither males, nor females from either region have ever reproduced on the opposite side of the strait. Comparisons of molecular divergence with bats from a closely related species (M. blythii) suggest that the North African clade is possibly a distinct taxon warranting full species rank. We provisionally refer to it as Myotis cf punicus Felten 1977, but a definitive systematic understanding of the whole Mouse-eared bat species complex awaits further genetic sampling, especially in the Eastern Mediterranean areas.

BACKGROUND: Biological agents (BA) have recently completed the treatment options in auto-inflammatory diseases (AID) in children with the aim to improve the outcome. TNF-α blocking agents have been the first BA successfully used in children. However, other biological agents targeting cytokines including IL-1 and IL-6 have been shown to be effective (anti-IL-1/6), especially in AID like systemiconset juvenile arthritis (SoJIA) or cryopyrine-associated periodic syndrome (CAPS). In Switzerland, Etanercept has been approved for the treatment of JIA since 2000 and Canakinumab for the treatment of paediatric CAPS since 2009.OBJECTIVES: Evaluation of the use of biological agents in AID in Western Switzerland.METHODS: We selected all patients with AID seen in the Réseau Romand de Rhumatologie Pédiatrique (Lausanne, Geneva, Aigle, Sion, and Neuchâtel) who were treated with the following BA: anti-TNF-α (Etanercept, Infliximab, Adalimumab) and Abatacept, and anti-IL-1/6 (Anakinra, Canakinumab, Tocilizumab). We looked at minor and major adverse events and the activity of the disease before and after treatment with BA and with special regards on anti-IL-1/6.RESULTS: Among 921 children and adolescents followed between 2004 and 2010, we selected 85 patients with AID (PFAPA: 40, FMF: 6, HyperIgD: 1, CAPS: 3, SoJIA: 34). Only patients with CAPS and SoJIA were treated with BA. They had a mean age of 9 years (3-22) and F: M ratio of 1.6:1. 7 patients were treated with one BA, 6 patients with 2 different BAs and 3 with 3 BAs. 3 patients with CAPS were treated with anti-IL-1 and responded very well. 13 SoJIA patients were treated with BA (anti-TNF-α: 8, Abatacept: 1, anti-IL-1/6: 8). 4 patients treated by anti-TNF-α were switched to anti-IL-1/6 because of lack of response to treatment (cf Table 1). We did not have any serious adverse events and no serious infections.CONCLUSIONS: Patients with SoJIA and CAPS clearly benefit from treatment with BA. General tolerance was good. In the CAPS group the response to IL-1 was excellent. In SoJIA, 3/4 patients, switched from anti-TNF-α to anti-IL-1/6 for lack of therapeutic response, did not respond well to the second medication. These patientsseem to represent a population relatively resistant to treatment with BA. Due to the low number of patients in our cohort, the response to BA in SoJIA patients non-responder to anti- TNF-α agents should be further studied.

The nutritional status of cystic fibrosis (CF) patients has to be regularly evaluated and alimentary support instituted when indicated. Bio-electrical impedance analysis (BIA) is a recent method for determining body composition. The present study evaluates its use in CF patients without any clinical sign of malnutrition. Thirty-nine patients with CF and 39 healthy subjects aged 6-24 years were studied. Body density and mid-arm muscle circumference were determined by anthropometry and skinfold measurements. Fat-free mass was calculated taking into account the body density. Muscle mass was obtained from the urinary creatinine excretion rate. The resistance index was calculated by dividing the square of the subject's height by the body impedance. We show that fat-free mass, mid-arm muscle circumference and muscle mass are each linearly correlated to the resistance index and that the regression equations are similar for both CF patients and healthy subjects.

Orientado pela teoria das relações de gênero, este artigo examina as principais leis, planos e programas federais que especificam as diretrizes nacionais das políticas públicas de educação no Brasil. Entre os documentos privilegiados para análise destacam-se a Constituição Federal (CF/1988), a nova Lei de Diretrizes e Bases da Educação (LDB/1996), o Plano Nacional de Educação (PNE/2001) e os Parâmetros Curriculares Nacionais do Ensino Fundamental (PCN/1997). Mostramos que adotar a ótica de gênero para a análise dessas políticas permite avaliar como elas podem facilitar ou dificultar a aquisição de padrões democráticos, uma vez que a política educacional não tem um papel neutro, dissociado de preconceitos, entre os quais destacamos o de gênero.
