Abstract: objective: detect of cardiac alterations in children with aids and compare their evolution with the administration of only one anti-retroviral and the recent cases who received drugs in combination. methods: we prospectively studied 47 children in 3 groups: group 1, 20 cases treated only with zidovudine; group 2, 10 patients treated initially with zidovudine and later with a combination of drugs and in group 3, 17 patients, who receiced two or three since the beginning. in all patients it was done chest x-ray, ekg and echocardiography every 6 months and after death complete pathological study. results: among the 45 patients cases 26 (57%) were index cases. malnutrition, diarrhea tachycardia, signs of congestive heart failure, pericardial effusion, abnormal ventricular repolarization and arrhythmias were more frequent in group 1. echocardiographic abnormalities were present in 10 (50%) children of group 1. they were less frequent in the others two groups. in regard to the outcome in group 1, two patients had worsening of sings of cardiomyopaty and 4 died. cardiac dysfunction in all cases of group 2 and 3 improved with the medication. conclusion:- the children who received combination and their cardiac alterations had more favorable outcome than those who received only one drug.
Trifuntional Oligoetherols and Polyurethane Foams with Carbazole Ring  [PDF]
Renata Lubczak
Open Journal of Organic Polymer Materials (OJOPM) , 2012, DOI: 10.4236/ojopm.2012.21001
Abstract: The method of synthesis of trifuntional oligoetherols with carbazole ring from 9-(2,3-epoxypropyl)carbazole and die- thanolamine and oxiranes like ethylene and propylene oxide was presented. Structure and some physicochemical prope- rties of the products were described. The oligoetherols were demonstrated as good substrates for synthesis of polyure- thane foams of enhanced thermal resistance. It has been found that the obtained foams are rigid at room temperature and their apparent density was 34 kg/m3- 44 kg/m3. The water uptake was low, maximum to 10.5 mass%. Dynamic thermal analysis of this foams showed that 5% mass loss starts at 200?C - 220?C, while temperature of 50% mass loss was 340?C - 370?C. Concomitantly the increase of compression strength was observed.
Lex Arbitri, Lex Curia and Lex Contractus in Brazilian Jurisdiction  [PDF]
Renata Thiebaut
Beijing Law Review (BLR) , 2016, DOI: 10.4236/blr.2016.72014
Abstract: International arbitration arose as a global phenomenon with the growth of transcontinental trade in a progressive smaller world. As its role and importance have become defined, the use of arbitration as an alternative dispute resolution has increased all around the world accordingly. However, even with unified international documents, such as the 1958 New York Convention, 1965 Washington Convention, 1985-2006 United Nations Commission on International Trade Law, or UNICITRAL Model Law, arbitration has been approached differently domestically, thus facing conflicts or controversies. This paper has as main objective to explain the key points concerning arbitration within the Brazilian legal system. The evolution of arbitration will be studied since the Iberian Union in the colonial era in order to bring about the formation of its legal characteristics. Besides, the current Brazilian Arbitration Act, promulgated in 1996, will be analyzed focusing on its provision gaps. The Sulamerica-Enesa arbitral award will be the case study of this paper, which will contribute to a better understanding of the increase in conflicts with the use of this method of dispute resolution. Last, an overview of the Brazilian arbitration legislation as well as its “gaps” will determine that in spite of arbitration being successfully implemented in Brazil, there is still an eminent need to improve legislation, which will be substantial to avoid further conflicts in lex arbitri, lex curia and lex contractus within arbitration itself.
Evaluation of phosphorus and nitrogen balances as an indicator for the impact of agriculture on environment: A comparison of a case study from Poland and Mississippi US  [PDF]
Renata Gaj, Nacer Bellaloui
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32036
Abstract: The objective of this research was to quantify the changes of nitrogen (N) and phosphorus (P) balances in Poland and Mississippi (MS), USA. Nutrient balances were calculated as difference between input and output in the agricultural system according to Organisation for Economic Cooperation and Development (OECD) methodology. A positive nutrient balance means that a potential environmental problem may result from that nutrient; a negative nutrient balance means there is a potential yield loss. The N and P soil surface balances for Poland and MS were calculated for the year 1998 through 2008. The results showed that both MS and Poland had positive N and P balances, indicating that there was a surplus of N and P. The average balance for N was 48 kg·ha-1 in Poland and 102 kg·ha-1 in MS. For P, it was 3 kg·ha-1 in Poland and 19 kg P kg·ha-1 in MS per cultivated area. This research demonstrated that the nutrient balance of N or P depended on the efficient use of each nutrient and type and source of fertilizer used. This research is significant for N and P fertilizer management and their impact on agriculture production and environment health.

Marina Franco, Renata Jasionowska
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.43016

The paper deals with the development of a rapid and efficient Capillary Zone Electrophoresis (CZE) method for Quality Control analysis of pharmaceutical preparations containing antihistamines, decongestants, anticholinergic remedies and preservatives. Active ingredients of interest are: ChlorPheniramine Maleate (CPM), DiPhenhydramine Hydrochloride (DPH), Ephedrine hydrochloride (E), Isopropamide Iodide (II), Pheniramine Maleate (PM), Lidocaine hydrochloride (L), Tetracaine hydrochloride (T), Clopamide Hydrochloride (CH), DiHydroErgochristine (DHE), PhenylEphrine hydrochloride (PE) and Acetaminophen (A). Preservatives studied are: MethylParaben (MeP), EthylParaben (EtP), PropylParaben (PrP), ButylParaben (BuP), p-HydroxyBenzoic Acid (p-HBA). All these analytes were separated in a single run using 60 mM tetraborate buffer solution (TBS) pH = 9.2 as a BackGround Electrolyte (BGE) by using an uncoated fused silica capillary of I.D. = 50 mm and applying a voltage of 25 kV in the first part of the electropheretic run (up to 5.8 min) and 30 kV for the remaining time. The hydrodynamic pressurization of the inlet vial was 20 psi at 7.2 min. up to the end of analysis. Total separation time was of 7.5 min. The method was then successfully validated and applied to the simultaneous determination of active ingredients and preservatives. Good repeatability, linearity, and sensitivity were demonstrated. Precision of migration time (tm) was RSD% < 0.53% and of corrected peak area (Ac) was RSD% < 6.15%. The linearity evaluation gave 0.9928 < r2 < 1.000. LOD and LOQ, accuracy (recovery) and ruggedness were evaluated for each analyte demonstrating the good reliability of the method. Analyses of some pharmaceutical real samples were performed.

Revista de Nutri??o , 2008, DOI: 10.1590/S1415-52732008000700012
Abstract: objective: describe and evaluate daily food consumption among families experiencing food insecurity. methods: a population survey was conducted in campinas, s?o paulo, in 2003, with 456 families. one qualified member of each family was interviewed about their daily intake of 14 food groups. for the food insecurity classification, a scale divided into three categories was used: 1) food security; 2) mild food insecurity; 3) moderate or severe food insecurity. results: significant differences were found among the categories of food insecurity with respect to food consumption. the proportion of respondents from families experiencing moderate or severe food insecurity or mild food insecurity that did not consume dairy products, fruits, vegetables, meats, on a daily basis is significantly higher than respondents from families who are food-secure (p<0.001). among food-secure families, 73.7% consumed at least one fruit per day and 62.1% consumed dairy products every day. these percentages were 11.4% and 5.5%, respectively, in families with moderate or severe food insecurity. the majority of these families consumed only grains, oil, sugar, and dried beans on a daily basis, and they spend roughly 68% of their monthly income on food. there are significant differences in the frequency of the main daily meals among the food security categories, which is always less frequent among families with moderate or severe food insecurity. conclusion: families experiencing moderate or severe food insecurity have a boring diet, composed basically of energetic foods. even among food secure families, adequate diet quality was not always present. these results show that it is necessary to strengthen nutrition education efforts in public policies that aim to improve food security and promote healthy diets.
Rapid and Sensitive CZE Method for Quality Control Analysis of Pharmaceuticals Containing Pseudoephedrine, Triprolidine and Paracetamol  [PDF]
Sonia Di Berardino, Renata Jasionowska
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.59069
Abstract: A rapid and sensitive CZE (Capillary Zone Electrophoresis) method for pharmaceutical analysis was developed and fully validated. The active compounds: Pseudoephedrine hydrochloride (PSE), Triprolidine hydrochloride (TRI) and Paracetamol (PAR) were separated and quantitatively determined using the tris-borate 30 mM buffer at pH = 9.0 as a Background Electrolyte (BGE). The electrophoretic separation was carried out at 25 kV in an unmodified fused silica capillary of I.D. = 50 μm with a “bubble-cell” for UV detection at 210 nm and 25°C. The separation was reached in about 3 min. After calibration the method was applied for analysis of three commercially available pharmaceutical preparations. The repeatability (RSD%) of migration time (tm) was ranging between 0.47% and 0.90% and of peak areas (A) between 0.63% and 3.64%. The Limit of Detection (LOD) values was of 0.19 μg/mL, 0.31 μg/mL and 0.08 μg/mL for respectively PSE, TRI and PAR. The results obtained in this study showed that the proposed method was useful in routinely analysis of pharmaceuticals.
A medicaliza??o do sofrimento psíquico: considera??es sobre o discurso psiquiátrico e seus efeitos na Educa??o
Guarido, Renata;
Educa??o e Pesquisa , 2007, DOI: 10.1590/S1517-97022007000100010
Abstract: this study offers a critical analysis of the changes observed in the treatment of psychiatric suffering in recent history, noting the contribution from factors such as: the standardization of symptoms brought by the successive editions of the dsm series (diagnostic and statistical manual of mental disorders), the results of researches in neuroscience that attempt to establish the psychic functioning upon organic bases, and the huge development of psychopharmaceuticals as a result of massive financial investments. the combined action of this group of factors had as its effect the loss of the notion of sense/meaning of the symptoms and subjective sufferings, which belongs to classical psychiatry, and the growing medicalization of the individuals in contemporary society. the text seeks to outline a picture of how a new truth about the psychic sufferings was produced, and expands this analysis by showing that the medicalization procedures developed for the treatment of the adult population were extended also to children. it reviews the evolution of the treatment of children, marking the interaction between pedagogy and medicine in the constitution of child psychiatry. in addition to that, the text tries to reveal the effects of this truth upon the subjects, identifying the way in which the technical discourse (particularly influenced by the medical-psychological discourse) has been given a place in the contemporary world, and how its has influenced education. it underlines, as products of this process, the banalization of existence, the naturalization of suffering, and the blaming of individuals for the accidents of life, and argues that the psychologization of school may nowadays be replaced by the psychiatrization of school discourse. the articulation knowledge/truth/power is investigated here from the texts of michel foucault.
