Sri Vidawati, Silvia Barbosa, Pablo Taboada, Eva Villar, Antonio Topete, Victor Mosquera
Advances in Biological Chemistry (ABC) , 2018, DOI: 10.4236/abc.2018.85008
Abstract: The Biodegradable nanoparticles from poly(lactic-co-glycolic acid) (PLGA) have been extensively investigated for sustained and targeted/localized delivery of different agents. Many parameters are required in the synthesis of a biodegradable polymeric nanoparticle. We report the synthesis of human serum albumin (HSA)-superparamagnetic iron oxide nanoparticles (SPIONs) loaded PLGA nanoparticles. All nanoparticles were characterized using a TEM image, UV-Vis spectroscopy measurements, Zeta Potential, and PPMS for magnetizations. This study described and investigated the interesting phenomenon in the synthesis development of HSA-SPIONs loaded PLGA nanoparticles. The result showed that the stability of HSA-SPIONs loaded PLGA nanoparticles for potential applications such as in protein delivery.

Abstract: Na última década multiplicaram-se as publica es e a utiliza o da cirurgia de controle de danos, resultando num número crescente de pacientes deixados com o abdome aberto (ou peritoneostomia). Uma das consequências nefastas do abdome aberto s o as hérnias ventrais gigantes que resultam da impossibilidade de se fechar o abdome durante a interna o hospitalar do paciente. Para minimizar esta sequela têm surgido na literatura diferentes tipos de abordagem. Para abordar este tópico, a reuni o de revista "Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE) optou por n o analisar sistemas comerciais de fechamento abdominal dinamico, com exce o da terapia de press o negativa ou vácuo. O grupo fez uma avalia o crítica dirigida de três artigos mais relevantes publicados recentemente sobre fechamento sequencial da parede abdominal (com tela ou sutura) mais vácuo. Nesta avalia o foram incluídos dois estudos retrospectivos mais um estudo prospectivo. Baseados na análise crítica desses 3 estudos mais a discuss o que contou com a participa o de representantes de 6 Universidades e realizada via telemedicina, s o feitas as seguintes recomenda es: (1) a associa o de terapia de press o negativa com tra o fascial constante mediada por tela ou sutura, ajustada periodicamente, parece ser uma ótima estratégia cirúrgica para o tratamento de peritoneostomias. (2) O fechamento abdominal primário dinamico com sutura e mediada por tela parece ser mais econ mico e eficiente do que deixar o paciente com uma hérnia gigante e planejar uma reconstru o complexa tardiamente. Novos estudos com grupos maiores de pacientes separados de acordo com as diferentes apresenta es e doen as s o necesários para definir qual o melhor método cirúrgico para o tratamento de peritoneostomias. The last decade was marked by a multiplication in the number of publications on (and usage of) the concept of damage control laparotomy, resulting in a growing number of patients left with an open abdomen (or peritoneostomy). Gigantic hernias are among the dreaded consequences of damage control and the impossibility of closing the abdomen during the initial hospital admission. To minimize this sequela, the literature has proposed many different strategies. In order to explore this topic, the "Evidence-based Telemedicine - Trauma & Acute Care Surgery" (EBT -TACS) conducted a literature review and critically appraised the most relevant articles on the topic. No commercially available systems for the closure of peritoneostomies were analyzed, except for negative pressure therapy. T

Abstract: the sowing direction influences soil surface roughness, which, combined with rainfall and other variables, e.g., canopy cover, affects soil water erosion. using a rotating-boom rainfall simulator, five tests of simulated rainfall were applied to black oat (avena strigosa), and vetch (vicia sativa), at a constant intensity of 64 mm h-1, between august and november 2006, to assess water and soil loss in the following treatment: mechanized seeding of oats in downslope rows; mechanized seeding of oats along contour lines; mechanized seeding of vetch in downslope rows, and mechanized seeding of vetch along contour lines. the experiment was conducted in two replications on an inceptisol, with a mean slope of 0.119 m m-1. the canopy cover was greater in oat than vetch until rainfall test 2 and higher in vetch in the tests 3 and 4, with no variation due to the sowing direction of the crops and increasing from the beginning to the end of the growth period. the time until the water started to run off was longer in the treatments with seeding along contour lines than downslope, in both crops; the maximum runoff rate along the contour lines was lower and the time until maximum runoff rate longer. the sediment concentration in runoff decreased over the rainfall tests; it was lower in oat than vetch, and 52 % lower in contour than downslope sowing. soil loss decreased over the rainfall tests; these losses were 12 % lower in oat and 56 % lower in vetch contour than downslope sowing; the water loss had the same performance as soil loss, although with lower magnitudes. the accumulated soil losses increased with accumulated rain volume (vr) and rain erosivity (ei30), between the first and fourth test, according to the equations: sl = 0.859 (1-e-0.0059vr) (r2 = 0.99) and sl = 0.832 (1-e-0.0004ei30) (r2 = 0.99).

Revista Latino-Americana de Enfermagem , 2007, DOI: 10.1590/S0104-11692007000600015
Abstract: this descriptive study aimed to evaluate the effectiveness of non-pharmacological strategies (nfs) on pain relief of parturients as part of a research instrument to be utilized in a doctoral dissertation. in order to evaluate the nfs, the analogous visual scale (avs) was used on 30 parturients attended at the humanized labor unit of a school-maternity hospital in natal, rn, brazil. of the six nfs (respiratory exercises, muscular relaxation, lumbossacral massage, shower washing, deambulation and pelvic swing), two were excluded post-test (deambulation and pelvic swing) for not being accepted by the parturients. the remaining nfs (respiratory exercises, muscular relaxation, lumbossacral massage, and shower washing) which reached satisfactory acceptation and applicability rates, were found to be effective in relieving pain of these parturients, and thus deemed adequate for use in the doctoral dissertation data collection process.

Abstract: where nutrients are lost by water erosion the eroded soil is impoverished and crop productivity is reduced, apart from the water contamination. soluble n in the runoff is biologically available and contributes to eutrophication of the water and, depending on the form and content in the water, may be toxic to aquatic organisms. in order to evaluate the n content in the form of ammonium and nitrate in the runoff water, an experiment was conducted with simulated rainfall from april to november 2006, on an inceptisol under conventional tillage. a combination of three factors was studied: crop type, sowing form and simulated rainfall test. the crops black oat (avena strigosa) and common vetch (vicia sativa) were studied, as well as the sowing forms: mechanical, along rows in slope direction; broadcast by hand; and mechanized along contour lines; and five simulated rainfall tests, at a constant and planned intensity of 64 mm h-1 and rainfall duration of 1 h. the first four rainfall tests were applied during the crop cycles and the fifth on the crop residues maintained on the soil surface. nitrogen application to oat as urea cover dressing, immediately before rainfall test 1, resulted in a higher n-nh4+ content in the runoff water from oat than from vetch, exceeding the acceptable level for the aquatic community. under rainfall on residues in decomposition on the soil surface, the content of soluble n-no3- in the runoff water was higher in the crops of contour sowing than of slope sowing. the contents of soluble n-nh4+ and n-no3- in the runoff water decreased from the beginning to the end of the crop cycles, but increased in the rainfall test on vetch mulch, to higher values than in the treatment with oat residue.

Abstract: soil tillage influences soil management and damages structure, reduces the porosity and water infiltration and increases surface runoff. a rotating-boom rainfall simulator was used to investigate the treatments: conventional tillage (ct), no-tillage in burn residue (nb), no-tillage in desiccated residue (nd), and traditional no-tillage in desiccated residue (nt), both cropped, as well as conventional tillage without crop (bare soil - bs), and native pasture treatment (np), in a typic hapludox soil, in the southern plateau of santa catarina state, brazil, from march, 2001 to february, 2004, with the objective of quantifying surface runoff. three simulated rainfall tests were applied in maize and bean crops and five in soybean crop. the surface runoff initial time (it) and surface runoff peak time (pt), the surface runoff constant rate (rr) and surface runoff volume (rv), and c coefficient of the rational equation were quantified. the it, pt, rr, rv and c coefficient changed with soil tillage treatments and with soil cultivation. the it and pt were smaller in the ct and bs treatments, while the rr, rv and rc were smaller in nd and nt treatments. the rr changed from 18 mm h-1 in nt to 44 mm h-1 in bs treatments, while the rc changed from 0.29 in nt to 0.71 in bs treatments. the ve varied from 106 m3 ha-1 in nd to 434 m3 ha-1 in bs treatments.
Exploring Coping Effectiveness and Optimism among Municipal Employees  [PDF]
Tuija Muhonen, Eva Torkelson
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.26090
Abstract: The aim of the study was to examine the relationship between coping, optimism, psychological and physical well-being. The effectiveness of the different coping strategies and the role of optimism were investigated by analyzing how they predicted psychological and physical well-being. Altogether 136 municipal employees participated in a questionnaire study. The results showed that the most adaptive or effective coping strategy concerning psychological and physical well-being was acceptance, which can be classified as engagement coping. Ineffective strategies regarding psychological well-being included disengagement coping strategies such as sub- stance use, behavioral disengagement and self-blame. An ineffective strategy regarding physiological well-being was denial, which can be classified as a disengagement strategy. Optimism correlated significantly with both psychological and physical well-being. However, when all the variables in the model were included in the regression analysis, optimism explained additional variance in physical well-being but not in psychological well-being.

Eva Hanuskova, Jana Plevkova
Open Journal of Molecular and Integrative Physiology (OJMIP) , 2013, DOI: 10.4236/ojmip.2013.31002
Abstract:

Histamine—the main product of mast cells plays critical role in the pathogenetic pathways of both allergic rhinitis and asthma. The novel concept of the unique airway diseases its only supported by the similarities within pathogenetic process. Antagonists of H1 and H2 receptors are quite effective in allergic rhinitis, but not effective enough in asthma. In an era of corticosteroids, leucotriene antagonists and Anti-IgE treatment, there is still a challenge to search for more effective, more acurate and more safe treatment option. Antagonists (inversive agonists) of histamine receptors H4 seems to be one of the promising targets in the allergic rhinitis and asthma treatment. The first H4 antagonist entered to clinics and the results from a proof-of-concept Phase II clinical study is expected to be disclosed soon. This review article summarizes current knowledge on H4R that have been collected in various studies sharing evidences about efficacy of H4R as a reasonable target for diseases with histamine involved pathogenetic pathways.

What Reasons Might the Other One Have?—Perspective Taking to Reduce Psychological Reactance in Individualists and Collectivists  [PDF]
Christina Steindl, Eva Jonas
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.312A170
Abstract:

Previous research has demonstrated a considerable amount of negative consequences resulting from psychological reactance. The purpose of this study was to explore opportunities to reduce the amount of reactance. Using the method of perspective taking as an intervention, the current study of 196 Austrians and 198 Filipinos examined whether reactance could be reduced and whether individualists and collectivists differ concerning reactance and their perspective taking abilities. Our results indicated that participants who took the perspective of the person who threatened them experienced less reactance than participants who did not take this approach. This was the case for people from both cultural backgrounds. Nevertheless, comparisons among the two cultural groups yielded different reactions to restrictions. This indicates that individualists are more sensitive to a self-experienced restriction than collectivists, but less sensitive to a restriction of another person. Consequently, we consider culture to be a crucial determinant in predicting the amount of reactance.
