Psychometrics of the Dyadic Coping Inventory in three language groups

This article introduces the Dyadic Coping Inventory (DCI; Bodenmann, 2008) and aims (1) to investigate the reliability and aspects of the validity of the Italian and French versions of the DCI, and (2) to replicate its factor structure and reliabilities using a new Swiss German sample. Based on 216 German-, 378 Italian-, and 198 French-speaking participants, the factor structure of the original German inventory was able to be replicated by using principal components analysis in all three groups after excluding two items in the Italian and French versions. The latter were shown to be as reliable as the German version with the exception of the low reliabilities of negative dyadic coping in the French group. Confirmatory factor analyses provided additional support for delegated dyadic coping and evaluation of dyadic coping. Intercorrelations among scales were similar across all three languages groups with a few exceptions. Previous findings could be replicated in all three groups, showing that aspects of dyadic coping were more strongly related to marital quality than to dyadic communication. The use of the dyadic coping scales in the actor-partner interdependence model, the common fate model, and the mutual influence model is discussed.

A common biological basis of obesity and nicotine addiction.

Smoking influences body weight such that smokers weigh less than non-smokers and smoking cessation often leads to weight increase. The relationship between body weight and smoking is partly explained by the effect of nicotine on appetite and metabolism. However, the brain reward system is involved in the control of the intake of both food and tobacco. We evaluated the effect of single-nucleotide polymorphisms (SNPs) affecting body mass index (BMI) on smoking behavior, and tested the 32 SNPs identified in a meta-analysis for association with two smoking phenotypes, smoking initiation (SI) and the number of cigarettes smoked per day (CPD) in an Icelandic sample (N=34,216 smokers). Combined according to their effect on BMI, the SNPs correlate with both SI (r=0.019, P=0.00054) and CPD (r=0.032, P=8.0 × 10(-7)). These findings replicate in a second large data set (N=127,274, thereof 76,242 smokers) for both SI (P=1.2 × 10(-5)) and CPD (P=9.3 × 10(-5)). Notably, the variant most strongly associated with BMI (rs1558902-A in FTO) did not associate with smoking behavior. The association with smoking behavior is not due to the effect of the SNPs on BMI. Our results strongly point to a common biological basis of the regulation of our appetite for tobacco and food, and thus the vulnerability to nicotine addiction and obesity.

Kinase signaling cascades that modulate peroxisome proliferator-activated receptors.

Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors involved in lipid and glucose homeostasis, inflammation and wound healing. In addition to ligand binding, phosphorylation can also regulate PPARs; the biological effects of phosphorylation depend on the stimulus, the kinase, the PPAR isotype, the residue modified, the cell type and the promoter investigated. The study of this dual regulation mode, which allows PPARs to integrate signals conveyed by lipophilic ligands with those coming from the plasma membrane, may ultimately offer new therapeutic strategies.

Sargassum muticum (Yendo) Fensholt, nueva cita para la Peninsula Iberica

Sargassum muticum (Yendo) Fensholt, feofícea originaria de Japón (Pacífico Oeste), está extendiendo rápidamente su área de distribución, asociada a los transportes de ostras japonesas (CRITCHLEY, A. & R. DIJKEMA, Bot. Mar. 27:211-216,1984). Actualmente está citada en el Japón, en la costa Pacífica de América del Norte, en el Atlántico europeo de Inglaterra, Canal de la Mancha y Holanda y en el Mediterráneo francés (CRITCHLEY, A. J. Mar. Biol. Ass. U.K. 63: 617-625, 1983).

Randomized double-blind controlled Phase I/IIa trial to assess the efficacy of malaria vaccine PfCS102 to protect against challenge with P. falciparum.

The aim of this Phase I/IIa double-blind controlled trial was to test the efficacy of the sporozoite-based malaria vaccine PfCS 282-383 (PfCS102) to protect against Plasmodium falciparum parasitaemia. 16 volunteers were randomized to receive twice 30 μg of PfCS102 formulated in Montanide ISA 720 or ISA 720 alone (control). Two weeks after 2nd immunization, volunteers were challenged using 5 infected mosquitoes. All vaccinees developed antibodies against PfCS102 versus none control. 8/8 vaccinees and 6/6 controls challenged developed malaria parasitaemia. The duration from infection to onset of patent parasitaemia was similar in both groups (214 h in vaccinees and 216 in controls). PfCS102 is safe and immunogenic but provides no protection against artificial challenge in its current formulation.

Morfologia e partição de assimilados na batateira em função de época de amostragem e de doses de potássio

Com o objetivo de avaliar o efeito de época de amostragem e da adubação potássica sobre a morfologia e partição de assimilados na batateira (Solanum tuberosum L.), foram realizados dois experimentos no campo: o primeiro para avaliar o efeito de doses da adubação potássica e o segundo para avaliação do seu efeito residual. Foram aplicadas seis doses de K no campo (0, 60, 120, 240, 480 e 960 kg de K2O ha-1) na forma de sulfato de potássio, em delineamento de blocos casualizados, com quatro repetições. Tubérculos da cultivar Baraka, uniformemente brotados, foram plantados em espaçamento 0,8 x 0,3 m. Amostraram-se plantas aos 20 e 48 dias após emergência (DAE) para avaliação de área foliar, comprimento de caule, números e produções de matéria fresca e seca de folha, caule e tubérculo e teores de matéria seca de folha e caule. Apenas o comprimento de caule aumentou com as doses de K, resultando em menor sombreamento da batateira. No primeiro experimento, aos 20 DAE, a batateira apresentava, em média, 42 folhas, três hastes, 5.389 cm² de área foliar, 157,1 e 216,4 g de matéria fresca de caule e de folha, respectivamente, e 6,2 e 9,2% de teor de matéria seca de caule e de folha, respectivamente.

Hypertension et grossesse [Hypertension in pregnancy]

Hypertension in pregnancy Hypertension in pregnancy, whether chronic or recently diagnosed, is always a matter of concern for the general practitioner or the obstetrician. Even if this situation often evolves favorably, and although a "wait and see" attitude may be preferred to an aggressive one in such cases, one should also be aware of how dramatic the outcome may also be. As a matter of fact, what is considered as one of the most frequent complications of pregnancy can run out of control, a possibility which shouldn't be dismissed. In this article, we shall discuss the various strategies for managing this disorder.

Efeitos de giberelina e ethephon na anatomia de plantas de cana-de-açúcar

O presente trabalho teve como finalidade analisar os efeitos da aplicação de giberelina (GA) e do ethephon (CEPA) na anatomia de plantas de cana-de-açúcar. Para o estudo da anatomia de caules e folhas foi realizada pulverização de plantas jovens a partir de sementes. Após 216 dias da semeadura, realizaram-se cortes das folhas +4, da região do nó +10 e dos entrenós +10 e montagem de lâminas permanentes. Observou-se que o tratamento com GA 50 mg L-1 manteve intensa atividade meristemática, havendo contínua formação de feixes vasculares com menor quantidade de fibras de esclerênquima. O GA 50 mg L-1 provocou diminuição em número e tamanho de células buliformes nas folhas +4. Verificou-se que CEPA 1.200 mg L-1, inibiu a atividade meristemática na região do nó +10, reduziu a quantidade de fibras de esclerênquima dos feixes vasculares e aumentou o número de células buliformes.

Efeitos de sistemas de preparo do solo no uso da água e na produtividade do feijoeiro

Este trabalho teve por objetivo comparar o plantio direto, em duas densidades de palhada, com outros sistemas de preparo do solo, quanto à eficiência do uso da água e à produtividade de duas cultivares de feijoeiro com diferentes arquiteturas de planta. O experimento foi conduzido por quatro anos em um Latossolo Vermelho-Escuro, em Santo Antônio de Goiás, GO, utilizando o delineamento em faixas, com parcela subdividida, com quatro repetições. As faixas A, paralelas a uma linha central de aspersores, consistiram de cinco lâminas de irrigação. Considerando a média dos quatro anos, as quantidades de água aplicadas em cada faixa foram de 399,8; 307,0; 216,8; 128,0 e 54,0 mm. As faixas B, transversais à linha central de aspersores, consistiram de cinco sistemas de preparo do solo: plantio direto, plantio direto mais cobertura morta, grade aradora, arado de aiveca e arado escarificador. Nas subparcelas foram plantadas as cultivares de feijão Aporé e Safira. A magnitude da resposta da produtividade do feijoeiro à lâmina de água aplicada variou com a cultivar e com o sistema de preparo do solo. O sistema de plantio direto, com adequada cobertura morta, propiciou maior economia de água em comparação aos demais sistemas de preparo do solo.

HDR brachytherapy boost and external radiotherapy for unfavorable prostate cancer patients

Purpose/Objective: To evaluate the outcome of prostate cancer patients treated with a combination of HDR Brachytherapy boost (HDR-BT) and 3D conformal external pelvic radiotherapy (EBRT) in a dose escalation study. Materials and Methods: 162 patients were followed between November 2004 and December 2010 . Two different dose escalation groups were done: group 1 (n= 92), 1 fraction HDR boost (9-10 Gy ) followed by EBRT (60 Gy in 6 weeks) - BED: 203-216 Gy and group 2 (n=70): 2 fraction HDR boost (18-19 Gy), 6 hours interval between fractions, followed by EBRT (46 Gy in 4.5 weeks) - BED: 233.3 -247 Gy; 116 pts (71.6%) received concomitant androgen deprivation. Patients were classified according to the MSKCC criteria into high (N=137) and intermediate (N=25) risk. Phoenix biochemical failure definition was used. Toxicity was scored by Radiation Morbidity Scoring Criteria (RTOG) Results: The mean follow-up was 41 (range 7-84) months. The 7- years cancer-specific and overall survival was 100% an 92%, respectively. The 7 years actuarial biochemical control rate was 89% and 100% for group 1 and 2, respectively. One patient from group 1 and two patients from group 2 never reached a low nadir. Two patients developed distant metastases 12 and 16 months after the treatment. In a multivariate Cox-regression analysis neither treatment nor risk group (intermediate vs. high risk) were associated with increased risk for biochemical failure. The RTOG grade 3 genitourinary early toxicity was 1.0% and 8.5% while gastrointestinal/genitourinary late toxicity was 7.6% and 1.4% for group 1 and 2, respectively Conclusions: HDR BT boost followed by EBRT appears to be a safe, feasible and effective treatment for patients with unfavorable localized prostate cancer. This study shows a beneficial effect on biochemical control in group 2 pts, however without statistical significance. Higher radiation doses (BED 233.3-247 Gy) do not seem to carry extra toxicity.

Rapid, simple and high yield production of recombinant proteins in mammalian cells using a versatile episomal system.

Many research projects in life sciences require purified biologically active recombinant protein. In addition, different formats of a given protein may be needed at different steps of experimental studies. Thus, the number of protein variants to be expressed and purified in short periods of time can expand very quickly. We have therefore developed a rapid and flexible expression system based on described episomal vector replication to generate semi-stable cell pools that secrete recombinant proteins. We cultured these pools in serum-containing medium to avoid time-consuming adaptation of cells to serum-free conditions, maintain cell viability and reuse the cultures for multiple rounds of protein production. As such, an efficient single step affinity process to purify recombinant proteins from serum-containing medium was optimized. Furthermore, a series of multi-cistronic vectors were designed to enable simultaneous expression of proteins and their biotinylation in vivo as well as fast selection of protein-expressing cell pools. Combining these improved procedures and innovative steps, exemplified with seven cytokines and cytokine receptors, we were able to produce biologically active recombinant endotoxin free protein at the milligram scale in 4-6weeks from molecular cloning to protein purification.
