Abstract: Using articles on psychotherapeutic management in Geltast Therapy published in Brazil between 2005 and 2015 as a basis, an academic literature search was performed from the Scielo data base in the Pesic site. We obtained a brief result containing 46 articles whose vast majority emphasized current clinical practices; even though, some articles indicate a propensity for rupture of this restricted tendency in favor of an integrating perspective, seeing the individual as a whole, in order to facilitate the autonomy expansion of public service users of clinical psychology. It was also observed that, for the past five years, there has been an increase in scientific production focused on clinical procedures that envisaged public policies which contributed for the renovation of the semantic field. We concluded by stressing the importance of development of research in the area of psychotherapeutic process, based on a more ecological dimension before the world.

Abstract: urea is the main nitrogen source used in flooded rice fields, but it is prone to ammonia volatilization losses. the use of n-(n-butyl) thiophosphoric triamide (nbpt) urease inhibitor, as urea additive, can reduce this inconvenient, inhibiting temporarily urea enzymatic degradation. an experiment was carried out on a planossolo háplico (albaqualf), from october 2004 to april 2005, in cap?o do le?o, rs, brazil, to evaluate the effect of nbpt inhibitor-treated urea on nitrogen losses by ammonia volatilization, rice grain yield, and rice nitrogen accumulation, in two soil moisture conditions. the treatments were arranged as a randomized complete block with two soil moisture conditions (moist and muddy), two nitrogen sources (non treated urea and urea treated with nbpt) and three time intervals between nitrogen application and flooding (1, 5, and 10 days) in a factorial design with four replications. nitrogen rate was 120kg n ha-1, applied at 4- to 5- leaf stage (90kg n ha-1) and at panicle differentiation (30kg n ha-1). volatilization losses as ammonia from the urea treatment varied from 15% (muddy soil) to 22% (moist soil) of the applied n, when the time interval between nitrogen application and flooding was 10 days. addition of nbpt reduced 83% and 88% ammonia volatilization losses in muddy soil and moist soil conditions, respectively. for the 10 days interval between nitrogen application and flooding, nbpt treated urea promoted greater rice yield and nitrogen accumulation, compared to non treated urea. the use of nbpt inhibitor makes possible applying urea up to ten days before flooding with no decrease on rice grain yield and nitrogen accumulation.

Abstract: Objectives: To describe the prevalence of intestinal parasitosis in patients who sought a Basic Health Unit and get to know the conditions and socio-environmental characteristics of a population of peri-urban area of Manaus - AM, Brazil. Methods: A study conducted by spontaneous demand of patients in a Basic Health Unit, Northern Zone of Manaus, Amazonas, between April and July 2007, conducting parasitological examination in 400 stool samples by Hoffmann-Pons-Janer’s method, and interviews. Results: From the total, 271/400 (67,8%) contained parasites; 181/268 (45,25%) samples were of females; 147/224 (36,7%) aged between 19 and 85 years; 119/170 (29,75%) with incomplete elementary school; 207/299 (51.75%) with a family income between one and three minimum wages; 220/316 (55%) were natural from Amazonas; 192/284 (48%) worked at home; 199/298 (49,7%) consumed water from artesian public well; 106/152 (26.5%) treated the water; 165/248 (66%) did not treat the consumed water. The most frequent helminthes found: Ascaris lumbricoides 48 (12%), Enterobius vermicularis 44 (11%), Ancilostomídeos 38 (9,5%). Protozoa: Entamoeba histolytica 83 (20,8%), Entamoeba coli and Endolimax nana, 79 (19,8%) e 79 (19,8%) respectively, Giardia lamblia 41 (10,3%) and Iodamoeba butschlii 17 (4,3%). It was observed monoparasitism for E. histolytica 83 (20,8%), biparasitism 104/271 (26%) E. histolytica and A. lumbricóides, E. histolytica and E. vermicularis, E. histolytica and G. lamblia. Conclusions: We recorded a high prevalence of parasites in young people with low income, low cultural level, predominantly women of the household. Among the environmental factors associated with these indexes are a deficiency in water services and sanitary sewer.

Abstract: Endophytic bacteria may influence agricultural production in several ways, including promoting plant growth. Two experiments were conducted in order to evaluate the combination of endophytic bacteria from the Brazilian Northeast region aims at the commercial introduction of the inoculation of these bacteria in micropropagated sugarcane plants using a temporary immersion bioreactor. One experiment was done in tubes with sterile commercial substrate, and the other was done in pots with soil; both were installed in a greenhouse. A mixed inoculation was performed in six inoculated endophytic diazotrophic bacteria in micropropagated sugarcane plants, variety RB92579. In the experiment with soil, the mixed inoculation significantly increased the shoot dry matter of plants without the addition of nitrogen fertilizer. However, the accumulation of total-N in the tissues showed no significant differences between treatments with and without nitrogen fertilization. The evaluation of micropropagated seedlings showed no increases in the parameters tested. The results showed that the response of inoculation in temporary immersion bioreactor micropropagation is possible, and that the application of homologous strains may have contributed to a better response by the interaction of endophytic bacteria with sugarcane RB92579. Further studies should be conducted to improve the methodology, which indicates a great potential to optimize this process on a commercial scale.
Stress prevention by modulation of autonomic nervous system (heart rate variability): A preliminary study using transcranial direct current stimulation  [PDF]

Open Journal of Psychiatry (OJPsych) , 2012, DOI: 10.4236/ojpsych.2012.22016
Abstract: Introduction: Transcranial Direct Current Stimulation (tDCS) is a non-invasive, technique for brain stimulation. Anodal stimulation causes neuronal depolarisation and long-term potentiation, while cathodal stimulation causes hyperpolarisation and long-term depression. Stressors are associated with an increase in sympathetic cardiac control, a decrease in parasympathetic control, or both. Associated with these reactions is a frequently reported increase in Low Frequency (LF) Heart Rate Variability (HRV), a decrease in High Frequency (HF) power, and/or an increase in the LF/HF ratio. Objectives and aims: The present work aims to explore the tDCS potential in the modulation of the Autonomic Nervous System (ANS), through indirect stimulation of Anterior Cingulate Cortex (ACC). Methods: Two subjects, a 39 year old female and a 49 year old male, gave informed consent. Saline soaked synthetic sponges involving two, thick, metalic (stainless steel) rectangles, with an area of 25 cm2 each have been used as electrodes, connected to Iomed Phoresor II Auto device. It has been delivered a 2 mA current, for 20 minutes, over the left Dorsolateral Prefrontal Cortex (DLPFC) (Anode). Spectrum analysis (cStress software) of HRV has been performed before and after tDCS administration. Results: The female/male subject results of LF power, HF power and LF/HF ratio, before tDCS administration, were, respectively: 50.1 nu/60 nu, 46.1 nu/21.7 nu and 1.087/2.771; and, after tDCS administration, respectively: 33.5 nu/52.7 nu, 47.6 nu/ 22.8 nu and 0.704/2.312. Conclusions: tDCS over the left DLPFC (left ACC) increased parasympathetic activity and decreased sympathetic activity, suggesting the importance of tDCS in the management of stress-related disorders.

Abstract: the influence of parent material, varying from plio-pleistocene sediments and basic volcanics, and topographic position, to soil genesis, was studied in a topolitossequence typical of savanna at the cauamé river catchment, roraima. we aimed to describe the soil variability under savanna by means of chemical, physical and mineralogical attributes. fourteen soil profiles were described and samples, allowing the identification of the following classes: yellow latosol, red latosol, yellow and red-yellow argisols, plinthosols, gleisols, fluvic neosols and vertisols. the mineralogy was determined by drx. the pedogenetical processes and soil characteristics were closely related with topographical-hydrological variation and underlying lithology. soils derived from pre-weathered sediments of the boa vista formation are generally of low fertility, with high acidity and kaolinite mineralogy and low fe-oxides contents. soils developed from basalt or under the influence of alluvia with mafic contribution all showed high base saturation (eutric) and clay mineralogy with the presence of 2:1 clays, with varying amounts of kaolinite. the occurrence of vertisols, degraded carbonatic nodules and eutric soils under savanna indicate quaternary drier paleoclimates in this part of north amazonia, during which carbonates were formed in the lower horizons of vertisols, in closed depressions.
