Amostragem seqüential (presença-ausência) para Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) na cultura do milho

The sequential sampling of insect pests (presence-absence) has become important in the last years, specially when the insects are difficult to be quantified. To solve this problem in relation to Spodoptera frugiperda (J. E. Smith), a sequential sampling plan was developed. The sample unit was evaluated considering the presence or absence of the insect, independently of its total number. The experiment was conducted in Jaboticabal, São Paulo State, Brazil, in three fields of 0.5 ha divided in 100 plots of 50 m2 (5 × 10 m). Each plot was identified with a number from 1 to 100. A threshold level of 20% was assumed to set the sampling plan. The analyzed data allowed two lines to be generated: the superior one, representing the condition in chemical control is recommended (S1=1.7095+0.1452N); and the inferior one, when chemical control is not recommended (S0=-1.7095+0.1452N). The sequential sampling was efficient to indicate if control of S. frugiperda on corn crop was necessary or not.

Comparação, em mulheres inférteis, de teste de avaliação psicológica com a análise psicanalítica clássica

This study aims to compare a psychological evaluation test to classical psychoanalysis in infertile women. Two hundred women were submitted to the Psychological Evaluation Test (PET). The sum of the scores for the responses ranged from 15 to 60 points, with scores ≥ 30 points being defined as psycho-emotional maladjustment (cut-off point: median + 25%). For comparison, a psychologist submitted the patients to a psychological examination simultaneously, who was unaware of the PET results. From the 200 patients, 66 (33%) presented a test with ≥ 30 points (psycho-emotional maladjustment) and 134 (67%) a test with < 30 points (normal). Upon psychological examination, 105 (52.5%) presented an abnormal evaluation and 95 (47.5%) a normal evaluation. For the PET, statistical analysis showed 82% efficiency, 62% sensitivity, 98% positive predictive value, 99% specificity, 70% negative predictive value, likelihood ratio for a positive test result 62, and likelihood ratio for negative test result 0.38. The PET proved to be a useful clinical instrument, being of help for the selection of patients with psychological needs induced by infertility.

Desenvolvimento de alevinos de trairão (Hoplias lacerdae) na ausência de luz

Sixty-six trairão (Hoplias lacerdae) fingerlings (average weight of 2.0±0.5 g and total length of 5.8±0.2 cm), trained to accept dry rations, were allotted to six 15-L aquariums, with aeration and controlled temperature (24.0±0.5°C), in a density of 0.7 juveniles/L, aiming to evaluate the effects of darkness on fish productive performance. The treatments consisted of two photoperiods: 12 hours light: 12 hours dark (12L:12D) and 0 hour light: 24 hours dark (OL:24D), with three replicates. Fingerlings were fed ad libitum a commercial extruded diet (42% CP), twice a day. The aquariums were cleaned daily for excrement withdrawal through siphoning, exchanging 1/4 total volume. At the end of the experiment (30 days), weight gain, feed:gain ratio and survival and cannibalism rates were evaluated. The results showed that darkness did not affect the productive performance of trairão juveniles.

Subjetividade sujeitada e prática psicológica: Perspectivas do sujeito da ação

Research problematizes readings on the so-called subject or agent of action as associated to group constitution and analyzes the implications of such interpretations in psychological practice and in the constitution of subjectivity. The article is based on interdisciplinary readings and on different areas of knowledge so that identity references overlying the modern subject of action may be problematized. Critical emphasis is foregrounded on the classical logic, identity and subjected subjectivity as a-temporal and universal factors of action in the real world. The problematization of subjectivity's construction and its relationships with modes of knowledge will contribute towards the establishment of critical theoretic and strategic interventions.

Ausência de arteriosclerose na porção intramiocárdica das artérias coronárias: Um mistério a ser resolvido?

Several studies show that portions of intramyocardial coronary arteries are spared of arteriosclerosis, involving morphological, embryological, biochemical and pathophysiological aspects. Endothelial function is significantly affected in the segment of transition, as estimated by the vasoactive response to Ach. These findings suggest that myocardial bridge can provide protection against arteriosclerosis by counteracting the negative effects of endothelial dysfunction. The intramyocardial portion's protection phenomenon deserves further scientific research on all research fronts. Improved morphological, biomechanical and especially physiological and embryological knowledge may be the key to a future window of opportunity for chronic arterial disease therapy and prevention. In addition, this review discusses possible therapeutic approaches for symptomatic coronary ischemia caused by myocardial bridges.

Alterações da densidade mineral óssea em vértebras de ratos wistar submetidos à ausência de carga nos membros pélvicos

The suspension of rats by the tail model is used to investigate the behavior of bone in animals unable to move around. Bone is an adaptative tissue that develops in structure and function, among other factors, in response to mechanical forces applied to it and metabolic demands that it will suffer. The absence of mechanical forces and deformation of bone that occurs causes a decrease in calcium deposition in the absence of stimuli on osteoblasts and osteocytes, favoring the action of osteoclasts, making bones weak and brittle. Therefore, the mechanical action is necessary to stimulate local bone response and thus provide growth and remodeling. The aim of this study was to evaluable by radiographic densitometry, the tail suspension for 15 and 36 days alter the bone mineral density of cervical vertebrae (C3), thoracic (T6) and lumbar (L1 and L3) of Wistar rats. Thirty Rattus norvegicus albinus, adult, male, Wistar strain, average body mass ± 350g, were divided into 3 groups: control (n = 10) - not suspended; S15 (n = 10) - suspended for 15 days and S36 (n = 10) - suspended for 36 days. For densitometric analysis vertebrae were radiographed, scanned, digitized and analyzed by the computer program ImageJ®. There was a statistically significant increase in bone mineral density in group S15, probably by the restlessness of the animals to the suspension, with a decrease in group S36, and this hypothetically is linked to the accommodation of the rats, concluding that the tail suspension altered bone mineral density in first time with a decrease over time.
