Duas estratégias e desafios comuns: a reabilitação psicossocial e a saúde da família

Este artigo tem por finalidade refletir sobre as Estratégias de Saúde da Família e de Reabilitação Psicossocial, no momento em que a atenção psiquiátrica e a atenção básica se colocam em estreita vinculação. Parte-se da experiência e da revisão de referenciais que abordam tais temas, identificando interfaces e desafios a serem superados para a transformação desses contextos sociais em espaços de trocas afetivas e materiais, de saberes e práticas mais criativas e flexíveis.

Reabilitação neuropsicológica pediátrica

A neuropsicologia investiga a expressão comportamental das disfunções cerebrais, isto é, a interação entre estruturas cerebrais preservadas e prejudicadas e as funções cognitivas, tais como linguagem, memória, atenção e outras. A neuropsicologia pediátrica possui especificidades: maturação, estratégias cognitivas, ensino formal e cultura, e características intrínsecas à reorganização cerebral. O objetivo da reabilitação neuropsicológica é estabelecer estratégias para adaptação de funções cognitivas afetadas em relação às demandas do ambiente da criança. A reabilitação cognitiva pediátrica auxilia crianças com deficiência mental, epilepsia, traumatismo craniencefálico, síndromes autísticas, tumores cerebrais, paralisia cerebral, etc. Programas de reabilitação neuropsicológica podem ser voltados para dificuldades acadêmicas ou para funções cognitivas. A investigação da efetividade de programas de reabilitação depende de diversos fatores. O neuropsicólogo deve contribuir para o desenvolvimento de novas estratégias de reabilitação cognitiva, ser qualificado para o uso das mesmas e partilhar, com a equipe interdisciplinar, as técnicas e experiências efetivas.

Extinction of a conditioned response in rainbow trout selected for high or low responsiveness to stress

Two lines of rainbow trout (Oncorhynchus mykiss) that exhibit divergent endocrine responsiveness to stressors also display disparate behavioral traits. To investigate whether the high-responding (HR) and low-responding (LR) fish also differ in cognitive function, the rate of extinction of a conditioned response was compared between the two lines. Groups of HR and LR fish were exposed to a paired conditioned stimulus (CS- water off) and unconditioned stimulus (US; confinement stressor). After exposure to 18 CS-US pairings, at least 70% of individuals of both lines acquired a conditioned response (CR) manifested as an elevation of blood cortisol levels on presentation of the CS only. Post-conditioning, the fish were tested by presentation of the CS at weekly intervals, for 4 weeks, with no further reinforcement, and the extinction of the CR in the two lines was compared. The decline in mean plasma cortisol levels after exposure to the CS over successive tests suggested that the CR was retained for a shorter period among the HR (<14 days) than LR fish (<21 days). The frequency of individuals within each line whose plasma cortisol levels indicated a stress response when exposed to the CS was significantly greater among the LR than HR fish at 14 and 21 days with no HR fish falling into this category at 21 days. At 28 days post-conditioning, there were no HR fish and only three LR fish were categorized as stressed. These results suggest that there are differences in cognitive function between the two lines. Possible mechanisms underlying these differences are discussed. (C) 2004 Elsevier B.V. All rights reserved.

Genetic structure of populations of Rhizoctonia solani AG-3 on potato in eastern North Carolina

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was developed to identify and differentiate genotypes of Rhizoctonia solani anastomosis group 3 subgroup PT (AG-3 PT), a fungal pathogen of potato. Polymorphic co-dominant single-locus PCR-RFLP markers were identified after sequencing of clones from a genomic library and digestion with restriction enzymes. Multilocus genotypes were determined by a combination of PCR product and digestion with a specific restriction enzyme for each of seven loci. A sample of 104 isolates from one commercial field in each of five counties in eastern North Carolina was analyzed, and evidence for high levels of gene flow between populations was revealed. When data were clone-corrected and samples pooled into one single North Carolina population, random associations of alleles were found for all loci or pairs of loci, indicating random mating. However, when all genotypes were analyzed, the observed genotypic diversity deviated from panmixia and alleles within and between loci were not randomly associated. These findings support a model of population structure for R. solani AG-3 PT on potato that includes both recombination and clonality.

MTA-induced neutrophil recruitment: a mechanism dependent on IL-1β, MIP-2, and LTB4

Objective: The objective of this study was to investigate the mediators and the resident peritoneal cells involved in the neutrophil migration (NM) induced by mineral trioxide aggregate (MTA) in mice. Study design: MTA (25 mg/cavity) was injected into normal and pretreated peritoneal cavities (PC) with indomethacin (IND), dexamethasone (DEX), BWA4C, U75302, antimacrophage inflammatory protein-2 (MIP-2), and anti-interleukin-1β (IL-1β) antibodies and the NM was determined. The role of macrophage (MO) and mast cells (MAST) was determined by administration of thioglycollate 3% or 48/80 compound, respectively. The concentration of IL-1β and MIP-2 exudates was measured by ELISA. Results: MTA induced dose- and time-dependent NM into mice PC, with the participation of MO and MAST. NM was inhibited by DEX, BWA4C, and U75302, as well as anti-MIP-2 and anti-IL-1β antibodies. In the exudates, IL-1β and MIP-2 were detected. Conclusions: This study suggests that MTA induces NM via a mechanism dependent on MAST and MO mediated by IL-1β, MIP-2, and LTB4. © 2008 Mosby, Inc. All rights reserved.

Cyclodextrin glycosyltransferase production by the Bacillus sp., subgroup alcalophilus using a central composite design

Cyclodextrin glycosyltransferase (CGTase) activity was produced by the Bacillus sp., subgroup alcalophilus in a culture medium containing cassava starch. A central composite design and response surface methodology were used to study the influence of carbon source (cassava starch), nitrogen sources (yeast extract and tryptone) and sodium carbonate in the production medium. Assays were performed in 300 mL Erlenmeyer flasks containing 100 mL of production medium maintained in a shaker at 150 rpm at 35±1°C for 72 h of fermentation. The independent variables [0.75% cassava starch, nitrogen sources (0.375% yeast extract and 0.375% tryptone) and 1% Na2CO3] produced an enzyme activity of 96.07 U mL-1.© Academic Journals Inc.

Optimal moment to change pressure regulator and sprayer kit on center pivot irrigation machines: application to a study case

A theoretical model developed by the authors for determining the optimal moment to substitute sprayer and pressure regulator kit on a center pivot irrigating potatoes and beans has been applied. The methodology compares the sum of the costs due to additional consumption of water and energy, maintenance and labor, as well as yield losses associated to areas with deficit or over irrigation to the costs due to buy and install a new sprinkling set on the pivot. The results showed that for a reduction of 3.07% of the Hermann and Hein’s Uniformity Coefficient (UCh), the substitution of the sprinkling module on the pivot is justified when potatoes and beans are cultivated.

Efeitos da terapia manual de Maitland em pacientes com lombalgia crônica

Introduction: The low back pain are a problema of health. Objective: to evaluate the effects of the Maitland´s manipulation in pain, fl exibility, functional capacity and quality of life of the patients with chronic low back pain. Method: Sxteen subjects, of both genders, with the age from 23-68 years old (48.69,± 11.61 years old) were evaluated by test sit and reach (TSA), Visual Analogue Scale (VAS) and answered the questionnaires of the quality of life Medical Outcomes Study 36- Item Short-Form Health Survey (SF-36) and the Roland-Morris Disability functional incapacity (RMDQ). The treatment was carried out twice a week, totaling 10 sessions. Each session lasted 30 minutes and consisted by Maitland´s techniques, applied as the symptoms evaluated at the beginning of each session. After 10 session, the subjects were re-evaluated. The data obtained in the assessments concerning the TSA and VAS were analyzed by Student t test, the data relating to the questionnaire were analyzed using the Wilcoxon non-parametric statistics test. For the interpretation was used signifi cance level of 5% (p≤0,05). Results: A signifi cant improvement was in the intensity of pain, disability, fl exibility and quality of life. Conclusion: The Maitland´s therapy showed effective, which suggests be an appropriate strategy for intervention for patients with chronic low back pain.

A Solid Film Electrode of Intermetallic Ag 2 Hg 3.02 for the Direct Determination of Folic Acid in Fresh and Processed Fruit Juices

AgSIE was used for the direct analysis of folic acid (FA), with a detection limit and lower level of quantitation of 6.8 x10-10 mol L-1 and 2.3 x 10 8 mol L-1. The analysis in fresh and processed fruits was done without any sample pretreatment. In strawberry and acerola juices, FA concentration level values were below the method detection limit. FA was detectable in peach (77.7 0.4 mg L-1 and 64.4 0.5 mgL-1), Persian lime (45.4 0.7 mg L-1), pineapple Hawaii (66.2 0.4 mgL-1), pear pineapple (35.3 0.6 mgL-1), cashew (54.4 0.5 mgL-1) , passion fruit (73.2 0.3 mgL-1), and apple (84.4 0.5 mg L-1 ).
