Poerschke, Ronaldo André;Silveira, Daniela Augustin;Lodi, Peterson;Titton, Wagner;Marx, Guilherme;Lampert, Alexandre Soares;
Jornal Vascular Brasileiro , 2012, DOI: 10.1590/S1677-54492012000100006
Abstract: background: the authors idealized a temporary shunt between the femoral artery and the medullar canal on long bones to keep the viability of acutely ischemic limbs, while waiting for a definitive treatment. objective: to assess the flow on temporary shunts between the femoral artery and the marrow canal of the tibia during two hours in experimental dogs, which had the femoral artery interrupted. methods: two groups with three dogs on the control group and six on the intervention group were allocated at random. the controls had the right femoral common artery interrupted. the intervention group received a shunt between the iliac external artery and the medullar canal of the right tibia in addition. after two hours, the measure of the ph, blood coloration, blood flow in sonar doppler on the ischemic limbs were performed. the lungs were withdrawn in thoracic block for anatomic-pathologic analyses. results: the capillary blood ph average of the limb extremities in the control group was 6.97 (±0.39) and in the intervention group was 7.25 (±0.46), with p<0.001, and the blood coloration in the intervention group kept the bright aspect in all animals. the shunts needed in average three irrigations with saline heparin solution to be kept unobstructed. the macroscopic and microscopic evaluation of the pulmonary tissue did not evidence fat emboli. conclusion: the artery osseous or artery medullar (marrow) shunt showed to be feasible on the technical point of view in the laboratory.
Fatal cold agglutinin-induced haemolytic anaemia: a case report
Gianluca Lodi, Daniela Resca, Roberto Reverberi
Journal of Medical Case Reports , 2010, DOI: 10.1186/1752-1947-4-252
Abstract: A 48-year-old Caucasian man presented to our hospital with symptoms of extreme asthenia caused by severe anaemia. The transfusion of red blood cells (O Rh-positive), started as prescribed by the emergency guidelines in force without pre-transfusion tests, induced fatal haemolysis because of the presence of high levels of anti-H antibodies in his blood, that reacted with the large amount of H antigen in universal (0) red blood cells.Emergency transfusion of universal red blood cells (0 Rh-positive or negative) is usually accepted by the international guidelines in force in emergency departments. In this report we describe a rare complication caused by the very high concentration in the recipient of cold agglutinins and the activation of the complement system, responsible for red blood cell lysis and consequent fatal cardiovascular shock. We conclude that emergency transfusion of universal red blood cells (0 Rh-positive or negative) may be dangerous and its risk should be assessed against the risk of delaying transfusion until the pre-transfusion tests are completed.Cold agglutinins were first described by Landsteiner in 1903 [1]. Their pathological action against red blood cells (haemolytic anaemia) and blood vessels (Raynaud's syndrome) was described some years later by Clough and Iwai [2,3]. In 1953 Schubothe coined the term: Cold Agglutinin Disease (CAD) [4].CAD is characterized by an auto-antibody [5] which is able to agglutinate red blood cells (RBCs) at temperatures lower than that of the body, and subsequently to activate the complement system responsible for lysis of RBCs.Patients show haemolytic anaemia of varying degrees of severity, as well as episodes of hemoglobinuria and acrocyanosis, which arise or worsen upon exposure to low temperatures.Cold agglutinin antibodies are mainly specific for the I/i and H RBCs membrane systems [6], and their production can be stimulated by Mycoplasma pneumoniae or infection by the Epstein-Barr virus, as well as by lymphop

Abstract: The aim of this work was to study the chemical composition, antioxidant and antibacterial properties of Achillea distans Waldst. et Kit. subsp. distans and Achillea distans Waldst. et Kit. subsp. alpina Rochel, from the Rodna Mountains (Romania). The identification and quantification of major phenolic compounds was performed by a HPLC-MS method. The total polyphenolic and flavonoid content was determined spectrophotometrically. The antioxidant activity was evaluated using the DPPH bleaching method, trolox equivalent antioxidant capacity assay (TEAC), hemoglobin ascorbate peroxidase activity inhibition (HAPX) assay, and an Electron Paramagnetic Resonance (EPR) spectroscopy method. A data indicated that A. distans subsp. alpina extract has more antioxidant activity than A. distans subsp. distans extract. Luteolin, apigenin, quercetin, caffeic and chlorogenic acids were present in the two extracts of A. distans, but in different amounts. Three flavonoids were detected only in A. distans subsp. alpina. The polyphenol-richer A. distans subsp. alpina extract showed a higher antioxidant activity than A. distans subsp. distans extract. A. distans subsp. distans extract showed inhibitory activity for Gram-positive bacteria, as evaluated with four species. The quantitative and qualitative differences between the two subspecies of Achillea distans could be used as a potential taxonomic marker in order to distinguish the species.
Determinants in Pay-What-You-Want Pricing Decisions—A Cross-Country Study  [PDF]
Tim Dorn, Augustin Suessmair
American Journal of Industrial and Business Management (AJIBM) , 2017, DOI: 10.4236/ajibm.2017.72010
Abstract: Pay-what-you-want (PWYW) pricing has attracted much attention recently. Current research focused on influencing factors and their power across social contexts and countries. This article empirically examines a comprehensive list of 10 empirically tested factors that influence individual price-setting but never have been investigated holistically. Results indicate: (1) some previously assumed influencing factors have stronger moderating effects than do others, and (2) these influences must be interpreted as influential clusters rather than individually, as not all constructs are of significantly differing influence on an individual’s pricing decision. Satisfaction (Cluster 1), price consciousness, and fairness (both Cluster 2) constitute the most crucial moderators, regardless of context. Four country contexts (i.e., Australia, Germany, Poland, United States) revealed further insights about the intercultural perspective of PWYW pricing: Whereas most of the influencing factors/clusters are of comparable importance across the tested countries, loyalty and reputation (Cluster 6) significantly differed in importance depending on country.

Nutrition Journal , 2006, DOI: 10.1186/1475-2891-5-3
Abstract: The objective of the study is to assess the impact of an elementary integrator composed of Spiruline (Spirulina platensis) and Misola (millet, soja, peanut) produced at the Centre Medical St Camille (CMSC) of Ouagadougou, Burkina Faso, on the nutritional status of undernourished children.550 undernourished children of less than 5 years old were enrolled in this study, 455 showed severe marasma, 57 marasma of medium severity and 38 kwashiorkor plus marasma. We divided the children randomly into four groups: 170 were given Misola (731 ± 7 kcal/day), 170 were given Spiruline plus traditional meals (748 ± 6 kcal/day), 170 were given Spiruline plus Misola (767 ± 5 kcal/day). Forty children received only traditional meals (722 ± 8 kcal/day) and functioned as the control group. The duration of this study was eight weeks.Anthropometrics and haematological parameters allowed us to appreciate both the nutritional and biological evolution of these children. The rehabilitation with Spiruline plus Misola (this association gave an energy intake of 767 ± 5 kcal/day with a protein assumption of 33.3 ± 1.2 g a day), both greater than Misola or Spiruline alone, seems to correct weight loss more quickly.Our results indicate that Misola, Spiruline plus traditional meals or Spiruline plus Misola are all a good food supplement for undernourished children, but the rehabilitation by Spiruline plus Misola seems synergically favour the nutrition rehabilitation better than the simple addition of protein and energy intake.Malnutrition constitutes a public health problem throughout the world and particularly in developing countries [1]. In Africa, more than 30% of the deaths of less than five year old children result directly or indirectly from malnutrition [2]. Since 1999, Burkina Faso has been confronted by protein-energy malnutrition with 13 % of the infant population affected by emaciation, 29% by growth retardation and 30% by insufficient weight [3]. The consequences of the protein-energy
The Effects of Social Interaction and Social Norm Compliance in Pay-What-You-Want Situations  [PDF]
Leon Paul Hilbert, Augustin Suessmair
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.58054
Abstract: Since Pay-What-You-Want is a relatively new field of study, the influence factors during the pricing process are not sufficiently explored. It was hypothesized that in a hypothetical Pay-What-You-Want situation, increased social interaction and social norm compliance would lead to a higher willingness to pay for a travel mug. In a laboratory experiment, 79 German students were randomly assigned to three groups which varied in the degree of social interaction. Social norm compliance was assessed with a questionnaire. A 3 × 3 between-group factorial ANOVA showed a significant main effect for social interaction (p = 0.025, η2 = 0.08), whilst social norm compliance was slightly not significant (p = 0.067, η2 = 0.03). Follow-up comparisons were calculated and the results discussed. The findings implicate that especially the degree of social interaction should be regarded, both by researchers and practitioners, as an important situational factor influencing the price in a Pay-What-You-Want situation.
Intra-Firm Inventory Management Model with Transshipments  [PDF]
Biri Anthony, Degbe Sewodo Augustin
American Journal of Industrial and Business Management (AJIBM) , 2017, DOI: 10.4236/ajibm.2017.71002
Abstract: This paper analyzes the implementation of transshipments among two independent locations which belong to one parent firm and the impact of transshipments, when implemented between these two locations. We examine how the possibility of such transshipments affects the optimal inventory orders at each location and find that, if each location aims to maximize its own profit, their inventory choices will not in general maximize joint profits. However, we find transshipment prices which if implemented by the parent firm as incentive design will make each location behave in order to optimize aggregate profit.
Aggregation modes of anionic oxacarbocyanines with polycations in solution and in ESAMs
Andrea Lodi,Glauco Ponterini
International Journal of Photoenergy , 2006, DOI: 10.1155/ijp/2006/72383
Abstract: Interaction of oxacarbocyanines D-G with three polycations in aqueous solutions results in the formation of two types of likely small, distorted aggregates rather than the classical J aggregates. On the contrary, the latter are extensively and almost exclusively obtained in electrostatically self-assembled multilayers (ESAMs) prepared by alternate polycation/dye adsorption on quartz substrates. The J-aggregate growth on supported polycations is qualitatively shared by the four cyanines, a fact that reveals the crucial role of the double anionic substitutions on the dyes. On the other hand, films with D and E, which are known to have a stronger tendency to give dimers in water, exhibit higher J-band intensities and stability upon drying relative to those with F and G. Based on these observations, we suggest that energetic factors associated with cofacial dye/dye van der Waals interactions, ultimately related with the degree of planarity of the conjugated chromophores, may still play a major role in controlling aggregation equilibria in these complex systems.
Plurilingüismo e surdez: uma leitura bakhtiniana da história da educa??o dos surdos
Lodi, Ana Claudia Balieiro;
Educa??o e Pesquisa , 2005, DOI: 10.1590/S1517-97022005000300006
Abstract: the history of the education of deaf people is marked by conflict and controversy. it is observed that although the discussions carried out in the last five centuries make reference to education, the questions related to the educational sphere itself have never been emphasized. in other words, the teaching methods and the practices were subjected to the linguistic factor and approached with the purpose of describing and sustaining the defense of the development of oral or sign language. in the present article discussions shall be made from the viewpoint of bakhtin's theory, considering the main facts occurred in the history of the education of deaf people throughout the centuries. the various ideologies that have permeated the discourses about deafness will be explained, as will the historical struggle between the brazilian sign language (libras) and the portuguese language, focusing on the processes determining the lack of incentive, for more than a century, to the use of libras in the educational processes of deaf people. the consequences of this history for our current reality will be pointed out. lastly, a brief exposition of a research carried out by the author will be made, pointing to processes that suggest that a transformation of the education of and by deaf people should be made, particularly with regard to the development of the subjects as readers, giving elements to the definition of new studies in the educational sphere.
A leitura em segunda língua: práticas de linguagem constitutivas da(s) subjetividade(s) de um grupo de surdos adultos
Lodi, Ana Claudia;
Cadernos CEDES , 2006, DOI: 10.1590/S0101-32622006000200005
Abstract: based on the realization of bilingual reading workshops, this work discusses some aspects that constitute the subjectivity(ies) of a group of adult deaf. grounded on discursive interactions in brazilian sign language (libras), such space allowed a transformation of the social places assumed by the subjects because it permitted the establishment of dialogs between life stories and the different social relationships constructed within and by the group. assuming that subjectivity is always relative, determined by the various looks of the others and constructed in distinct social-ideological places and times, and that it constitutes a plural event discursively marked, in which the self completes itself dialogically in its relationship(s) to the others, the discussions presented in this study highlight the need to rethink the educational spaces as loci of discursive interactions and thus of transformation and constitution of the subjects.
