índices de sustentabilidade municipal: o desafio de mensurar
Tania Moreira Braga,Ana Paula Gonalves de Freitas,Gabriela de Souza Duarte,Júlio Carepa-Sousa
Nova Economia , 2004,
Abstract: This article presents methodology for the construction of indices of local sustainability, applied to the cities of the Piracicaba River Basin (Minas Gerais). The proposed methodology combines measures of quality of the microregional environmental system; the quality of life in urban areas; the pressure exerted by anthropic activities on reproduction bases in the area and on the microregional environmental system; political and institutional capacity for local intervention. The river and its water basin are used as the main parameters for spatialization, integration and compatibility of indicators constructed on the basis of distinct methodology and disciplinary viewpoints. Located in the mid Rio Doce river basin, the Piracicaba River basin is within the area of influence of the Rio Doce State Park. It comprises a significant assembly of economic activities (steel, cellulose, and iron ore mining) with a high degree of anthropic impact, considerable urban concentration, and massive reforestations through the monocultural plantation of eucalyptus trees (coal and cellulose).This article presents methodology for the construction of indices of local sustainability, applied to the cities of the Piracicaba River Basin (Minas Gerais).

Abstract: soybean hay (glycine max (l.) merril) and marmalade grass hay (brachiaria plantaginea (link) hitch) pure or mixed were evaluated through in vivo digestibility trials with sheep. the trial was conducted in a shed of metabolic studies in the department of animal science at ufsm. the soybean hay (100%)-t1, soybean hay (67%) + marmalade grass hay (33%)-t2, soybean hay (33%) + marmalade grass hay (67%)-t3 and marmalade grass hay (100%)- t4, were evaluated in a completely randonmized design, with four repetitions. the soybean was harvested during the r5 to r6 stages while marmalade grass was harvested in the maturation stage.the percentage of crude protein decreased from 10.44% to 4.14%, for treatments from t1 to t4, while the coefficients of in vivo dry matter digestibility and total digestible nutrients remained near to 47% for all treatments. in the regarding to crude matter intake, the digestibility of dry matter and the digestible protein contents decreased when the percentage of marmalade grass in the diet was increased. the hays studied were considered of poor quality because of both maturation stages and losses that happened during the curing and storage process.
Preventing misdiagnosis in amniotic band sequence: a case report
Cristiane Rúbia Ferreira,Cibelle Freitas Pinto Lima,Ana Maria Andrello Gonalves Pereira de Melo
Autopsy and Case Reports , 2013,
Abstract: Amniotic band sequence (ABS) is an uncommon and heterogeneous congenital disorder caused by entrapment of fetal parts by fibrous amniotic bands, causing distinctive structural abnormalities involving limbs, trunk, and craniofacial regions. The incidence ranges between 1/1200 and 1/15,000 live births, but is higher in stillbirths and previable fetuses. The intrinsic theory attributes the constriction band syndrome as an inherent development defect of embryogenesis while the extrinsic theory proposes that an early amnion rupture is responsible for the adherent bands. It is also suggested that amputations and constriction rings might be due to vascular disturbances. Anomalies resulting from amniotic bands are quite variable and sometimes may simulate chromosomal abnormalities. The authors report a case of a 36-week-gestation male neonate who lived for 29 hours after a vaginal delivery with an Apgar score of 8/9/9. The mother was primipara, and the prenatal was uneventful except for two episodes of urinary tract infections. The newborn examination depicted multiple anomalies characterized by exencephaly, bilateral labial cleft with distorted nostrils and palate cleft. There was also facial skin tag band, exophthalmos with hypoplasia of the eyelids. The limbs showed distal amputation of the fingers in both hands and feet, oligodactyly associated with syndactyly in the left foot, ring constriction in the right leg, the presence of right hyperextension, and clubfoot. The upper limbs showed length discrepancies. Karyotype analysis was normal at 46 XY. The authors conclude that the recognition of the malformations secondary to ABS is important in genetic counseling to prevent misdiagnosis between chromosomal and secondary disruption disorders.

Health (Health) , 2017, DOI: 10.4236/health.2017.96067
Abstract:
Pulmonary function studies in obese individuals have alerted the pathophysiological changes due to weight gain. However, these changes are not fully explained yet. Objective: To evaluate and analyze the pulmonary function of obese adults in the city of Manaus (AM, Brazil) and to correlate the parameters of spirometry with weight and BMI. Method: A descriptive cross-sectional study, in which pulmonary function of 22 adults with grade III obesity was evaluated pre and post bronchodilator administration, performed at the Adriano Jorge Hospital Foundation—FHAJ. Results: Of the 22 patients evaluated, 6 were male and 16 were female; mean age was 37.1 ± 7.4 years, with a weight of 134.2 ± 28.6 kg and a BMI of 51.1 ± 9.4 kg/m2, corresponding to grade III obesity. Spirometry showed a reduction in values obtained from Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1) and Peak Expiratory Flow (PEF) in relation to those predicted, with 23% of restrictive disorders. There were negative correlations between BMI and PEF, weight and FVC, weight and PEF. The P value for correlation of weight and FEV1 is not statistically significant. Conclusion: Restrictive and obstructive disorders are prevalent in the population with grade III obesity. Correlations between pulmonary function and BMI/weight were negative for this specific population.

Abstract:

The cultivation of the marine species of shrimp Litopenaeus vannamei has emerged as one of the segments that best develop in the Brazilian aquaculture, representing the agribusiness that grew the most in recent years. Regarding the economic importance of the farming of this species in Brazil, further studies on genetic improvement were conducted. A F2 segregating population consisting of 192 samples for each G1 and G2 families, from crossing inbred lines was used for the studies performed in the present work. The genetic linkage analysis was based on polymorphic markers derived from nine AFLP (Amplified Fragment Length Polymorphism) primers. Fourteen genetic linkage groups including 103 segregating polymorphic markers were constructed covering350 cMfor G1 and four genetic linkage groups including 59 markers were constructed covering300 cMfor G2. Simple marker analyses were performed among individuals evaluated phenotypically, finding markers linked to genes that may be potentially important and useful to assess characteristics of economic importance for traits related to weight and the disease IMN (idiopathic muscle necrosis). The statistical model including markers explained major proportion of phenotypic characteristic weight in relation to disease incidence IMN.

Abstract: Extraoral traction (EOT) by occipital headgear is a widely used anchorage and orthopedic approach for the control of maxillary growth. The aims of this study were: 1) to test the hypothesis that headgear use may increase the risk of apical root resorption, using cone beam computed tomography (CBCT) to detect root resorptions of maxillary fi rst molars, and 2) to assess which roots are more prone to resorption and to which extent. A total of 112 maxillary fi rst molars from 56 patients at 52 to 288 months after orthodontic treatment were evaluated to detect apical root resorption on CBCT images. Patients were divided into two groups: Group 1, patients who used EOT for up to six months; Group 2, patients who did not use EOT. The Levander and Malmgren scoring system was used to classify the root apices of maxillary fi rst molars. Signifi cance was set at 5%. Kappa statistics was used to assess agreement; scores were evaluated twice, according to the study methods. There were no differences in the frequency and severity of apical root resorption of maxillary fi rst permanent molars in the two groups as detected by CBCT. The use of EOT did not show association with frequency and severity of ARR considering a long time of follow up.

Abstract: The present investigation details a green synthesis of silver nanoparticles (AgNP) using the essential oil of Syzygium aromaticum L. (clove) as reducing agent, which is a matrix with a high content of eugenol, an important compound for the reducing action of silver nitrate. The synthesis of AgNP was performed at different pH conditions (pH 7, 8, 9 and 10), and was monitored by UV-Vis Spectroscopy, Dynamic Light Scattering (DLS) and Transmission Electron Microscopy. The synthesized nanoparticles presented characteristic Surface Plasmon Resonance bands with maximum absorbance between 405 and 460 nm. The DLS analysis revealed particle sizes from 31 to 72 nm and zeta potential between -30.1 and -50.8 mV indicating good stability against the agglomeration of the particles in solution. The micrographs obtained by TEM showed different particle shapes and a predominance of spherical-shaped nanoparticles, and average size ranging from 27 to 94 nm. The clove-based silver nanoparticles were efficient in controlling the growth of Escherichia coli and Staphylococcus aureus bacteria, and the minimum inhibitory concentration ranged from 60 to 100 μL/mL. This study highlights the feasibility of clove essential oil as an alternative for the synthesis of silver nanoparticles by a simple, inexpensive and eco-friendly method.
The Gestalt Approach to Social Network Used by Generation X Parents  [PDF]
Adelma do Socorro Gonalves Pimentel, Gabriela Moreira de Faria
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.612151
Abstract: Studies on processes of subjectivation have shown changes in the way of individuals’ interaction and interpersonal relations due to the use of new computer and communication technologies. Such attitudes demand abilities and competences that parents between age of 40 and 55, contrary to their children, do not always find it easy to learn; thereby, we aim to find how those parents understand the uses and meanings of the social networks. This is a qualitative research in psychology directed by a gestalt perspective, by Sander’s phenomenological method. The research was approved by the ethics committee of Federal University of Pará. Semi-structured interviews were carried out with 6 parents chosen by the snow ball method. The data analysis consisted of a dialogue with references on the subjective effects of use of technologies. It is observed, among the results, that parents have used the social network to relate with their children and to work. It is concluded that, even though they have a limited knowledge of the technology, the informants use the social networks as a tool to find friends, for social interaction and prevention against urban violence and personal safety.

Abstract: the extended clinical nutrition conception is a new theme for the field of nutrition, especially clinical nutrition. given the process of reformulation of the health practice scenarios within the unified healthcare system, this theme instigates a substantial interest in scientific production, in the formation and clinical practice of the dietician with the use of communication competencies and the magnification of the technical and nutritional look on the process health-disease-care, which may contribute to the reconfiguration of the relationship dietician-patient with the purpose of amplifying its humanization. this trial shows how the conception of an extended clinical nutrition can contribute for the reflection on broadening the humanization of the relationship dietician-patient in health services. the trial is designed in two parts: the starting point and the continuation point. at the starting point, official publications on the social, historical and political conformations of the biomedical model and its repercussion on the clinical practice are analyzed. at the continuation point, nutritional clinic is observed as a social practice and the extended clinical conception is used for discussing the possibilities of restructuring clinical nutrition and broadening its knowledge and techniques beyond a restricted and restrictive biomedical model. finally, extended clinical nutrition is discussed, with the possibility of rethinking the relationship dietician-patient and proposing, in this sense, its humanization, the incorporation of non-biomedical contents, valuing practical knowledge and listening skills, the organization of knowledge and exploration of dialogue in the current practice of clinical nutrition.
