Miopatia do multicore: Análise histoquímica de uma família

In this paper the authors describe three cases of multicore myopathy in the same family. Case J was a white 77-year-old patient with proximal muscular atrophy and weakness, global hypotonia and global hypoactive deep tendon reflexes. Motor and sensory conduction studies were normal in all limbs. EMG examination showed a myopathic pattern with frequent spontaneous activity consisting of fibrillations and positive sharp waves. Histochemical reactions showed typical oxidative alterations of multicore myopathy. Cases 2 and 3 were the son and the daughter of case 1 respectively. They were both non-symptomatic patients with minimal EMG and histochemical alterations. These three patients illustrated the great clinical variability of this condition.

Flutua_̧tiao populacional de formas aladas de Brevicoryne brassicae (L.) (Hemiptera: Aphididae)

Studies related with the flight activity of aphids captured with traps can be useful to predict the appearance of alate forms in the field. It is also useful to understand the population dynamics of those insects. This work was carried out at the Faculdade de Ciências Agrárias e Veterinárias, Universidade Estadual Paulista, Jaboticabal, State of São Paulo, during the period from July 1997 to December 1999, aiming to determine the population curve of alate Brevicoryne brassicae (L.) in the region of Jaboticabal and the influence meteorological factors plays on it. The population survey was carried out in four places, and the alate aphids were sampled by yellow water traps. The influence of air temperature, relative humidity, rainfall and sunshine brightness was verified using stepwise regression. The first captures of alate B. brassicae in the traps began at the end of June. In the region of Jaboticabal, the population curve of alate B. brassicae showed the highest frequency of flights during September. The appearance of alate forms in kale fields at initial stage of development was favored by maximum and minimum temperatures of 26.4°C and 13.5°C, respectively; relative humidity of 75.1%, and reduced rainfall.

A família do portador de sofrimento psíquico e os serviços de saúde mental: Estudo de caso

This qualitative research, case study type, aimed at presenting the understanding of psychic sufferers in search for mental health services during emergency situation, partial hospitalization or in ambulatory services. 12 family members were interviewed. They reported difficulties in the attendance in the emergency room when the patient is in crisis, as well as doctors considering merely the present symptomatology and undervaluing their own knowledge of the sickening process. The day-care hospital is conceived as a place to provide care, occupation and should teach as a school. The ambulatory service represents for the family the possibility of the patient being responsible for their attendance to the consultations and for the correct use of the medication.

Testes de biocompatibilidade in vitro de duas formas comerciais do agregado de trióxido mineral

Recently, regular and white mineral trioxide aggregate (MTA) are being used in Dentistry as retrofilling materials. Genotoxicity and cytotoxicity tests form an important part of cancer research and risk assessment of potential carcinogens. Thus, the goal of this study was to examine the genotoxicity and cytotoxicity of regular and white MTA in vitro by the single cell gel (comet) assay and trypan blue exclusion test, respectively. Mouse lymphoma cells were exposed to two presentation forms of MTA at final concentrations ranging from 1 to 1,000 μg/mL for 3 h at 37°C. The results showed that both compounds tested did not produce genotoxic effects at all concentrations evaluated. Likewise, no statistically significant differences (p > 0.05) were observed in cytotoxicity. Taken together, our results suggest that regular and white MTA are not genotoxins and are not able to interfere in cellular viability as assessed by single cell gel (comet) assay and trypan blue assay, respectively.

A família do paciente em situação crônica de vida: a visão de enfermeiros de um hospital de ensino

This exploratory descriptive study, of qualitative nature had the purpose to study how the nurses from a hospital school see the family as care participants. Six nurses from clinics of chronically ill patients were interviewed. The data analysis allowed to infer that the nurses had only little knowledge of the family's thematic during graduation, making the relationship with the accompanying families very difficult. Daily care during hospitalization period is marked by easy moments when members are willing to participate in the process, and by difficulties when they attempt to break institutional rules. It was suggested that new nurses have theoretical foundation to attend the family in several scenarios of care. It was considered the need of investments in professional training, and that the advance of humanization of services implies in exchange and integration of knowledge among patients, family members, health professionals, support staff and managers beyond the science field.

Analise da relação entre escorregamento e formas de vertentes no município de cubatão (SP) e seus arredores

The city of Cubatão is a densely populated area with high industrial activity. In the area there are also important linear works as roads, railways, pipelines, aqueducts and lines of transmission of energy. The geological and geomorphological features of the municipality, combined with the human activities, make the site an area heavily prone to the landslides, so a region at high risk. In this work, landslide scars were extracted in aerial photos from 1985 and 1994, years that recorded a high incidence of landslides. Quantitative analysis of the relationship between the occurrence of scars and the forms of tracks were conducted, based on an intensive survey of scars in the region, represented by 2595 extracted scars, with the aim of contributing to a better understanding of the slipping processes in the Serra do Mar paulista and thus to the reduction of risks in the region. Achievements have concluded that the greatest percentage of slides in the region is linked to the strands straitght, followed by convex, which confirms previous studies conducted in the region, in a qualitative way or with a much lower number of scars.

Enfermeiros e a família do portador de transtorno mental.

This qualitative study aimed at investigating how mental health nurses acquired knowledge about the theme family during their academic training, how they see families in their daily practice, and how should professional training be considering the presence of the family in the care setting. Data were collected using semistructured questionnaires. Six nurses were interviewed. Data analysis allowed the establishment of three theme categories: Academic and professional training absence of the family theme; the nurses' perception of the family with a mentally ill member; and a new vision of the family the role of teaching. During undergraduate education, nurses acquired little knowledge about the theme family; in the institutional routine, they praise the family as a participant of care; and indicate that the need for knowledge about families is based on the interdisciplinary character of education.

Família de retificadores multipulsos com topologias diferenciais de transformadores

Multipulse rectifier topologies based on auto-connections or differential connections, are more and more applied as interface stages between the mains and power converters. These topologies are becoming increasingly attractive not only for robustness, but to mitigate many low order current harmonics in the utility, reducing the total harmonic distortion of the line currents (THDi) and increasing the power factor requirements. Unlike isolated connections (delta-wye, zigzag, etc.), when the differential transformer is employed, most of the energy required by the load is directly conducted through the windings. Thus, only a small fraction of the kVA is processed by the magnetic core. This feature increases the power density of the converter. This paper presents a mathematical model based on phasor diagrams, which results in a single expression able to merge all differential connections (wye and delta), for both step-up and step-down rectifiers for 12 or 18 pulses. The proposed family of converters can be designed for any relationship between the line input voltage and the DC voltage, unlike the conventional phase-shift voltage connections. An immediate application would be the retrofit, i.e. to replace a conventional rectifier with poor quality of the processed energy by the 12 or 18-pulse rectifiers with Wye or Delta-differential connections, keeping the original values for the input and load voltages. The simple and fast design procedure is developed and tested for a prototype rating 6 kW and 400 V on DC load.

Saúde da Família: O desafio de uma atenção coletiva

The Family Health Strategies, incorporated by the Ministry of Health in 1994, has consolidated the national policy of health care that has as its main care focus the family. In this model, this institution constitutes the first object of attention, understood from its environment and interaction. In recent decades, the Brazilian family structure is suffering profound changes that directly affect the practices of health care. This study redeem the family concepts and ideas and their social representations and still prove and present the importance and the necessity of the use of these ample instruments of collective boarding in health area: the APGAR, the genogram and eco-map, using the environment observation and family history - crucial factors to the reality of the nuclear family diagnosis - for further planning of health action strategies. It was concluded that the current structure of the family require training from the health teams, for physical, cultural, biological and social points of the family context for the correct use of the instruments cited, important tools for collective approach in the public health area.

Formas de ureia e doses de nitrogênio em cobertura na qualidade fisiológica de sementes de trigo

Besides increasing productivity, nitrogen fertilization may have positives effects on seed physiological quality. The objective of this study was to evaluate the effect of different forms and levels of urea in top dressing fertilization on the physiological quality of wheat seed genotypes. Seeds of three wheat genotypes (BRS 208, BRS Pardela and IWT 04008) were evaluated for four levels of nitrogen fertilization (0, 40, 80 and 120 kg.ha-1) in three forms of urea (conventional urea, urea with urease inhibitor and protected urea). The nitrogen fertilization was applied during tillering, 20 days after emergence. The seed nitrogen content, 1000 seed mass, germination and vigor (germination first count, cold test, seedling emergence in the field, dry weight of seedlings, accelerated aging and electrical conductivity) were evaluated. The IWT 04008 line and the cultivar BRS Pardela had seeds with a higher physiological quality than those of the cultivar BRS 208. The forms of urea and levels of nitrogen in topdressing did not affect seed physiological quality of the different wheat genotypes.

Formas de fósforo no solo após o cultivo de braquiária e tremoço branco

Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ruziziensis) and white lupin (Lupinus albus L.). The study was carried out in a greenhouse at Botucatu, State of São Paulo, Brazil. Brachiaria and white lupin were grown in pots with soil fertilized with 0, 20, 40, 60 and 80mg dm-3 P. The plants were grown for 60 days, when they were harvested and the soil was sampled. Dry matter yields of both species were increased with P rates. Soil bioactive P is increased with P fertilization, but is not affected by the plant species. White lupin is more effective in taking up the organic soil P, but Brachiaria was more effective in reducing the soil maximum P adsorption capacity.
