1. Voluntary and automatic orienting of attention during childhood development
Selective attention directs cognitive resources to relevant objects or events through either voluntary (top-down) or automatic (bottom-up) control. This paper analyzes voluntary and automatic orienting of attention during childhood development. Seventy-four children (6 to 10 years old) were asked to press a key in response to a visual target presented in a p

2. A expressão deficiente das chaperonas GRP78 e GRP94 conecta a sinalização de TLR4 com o estresse de retículo endoplasmático / Chaperone insuficiency of GRP78 and GRP94 links TLR4 signaling to endoplasmic reticulum stress
TLR4 activation and the induction of endoplasmic reticulum stress (ERS) are two of the most important mechanisms connecting excessive fat with insulin resistance. Recently, it was shown that activation of TLR4 can, per se, induce ERS, suggesting that TLR4 is a primary event in the induction of the cellular stress that contributes to increased inflammatory ge

3. Estudo de efetividade de intervenção psicológica de apoio na prevenção de sintomas de transtorno de estresse pós-traumático em pacientes submetidos à sedação e internados em Unidade de Terapia Intensiva / Effectiveness study of support psychological intervention in the prevention of posttraumatic stress disorder in intensive care unit sedated patients.
Goal: To evaluate the effectiveness of support psychological intervention in the prevention of Posttraumatic Stress Disorder (PTSD) in intensive care unit (ICU) sedated patients. Method: Randomized controlled clinical trial (treatment group G1 and control group G2). Adult sedated patients in ICU for more than 24 hours and with a history of delusional memorie

4. Detection of of porcine parvovirus (PPV) in swine fetal tissues / Pesquisa da presença de parvovirus suino (PVS) em tecidos de fetos de suinos
Swine female reproductive quality is mainly measured by return to estrus, litter size, abortion, stillbirth and mummies. Porcine parvovirus (PPV) transplacental infection is associated to fetal death at different gestacional age, and mostly with fetal mummification due to abscence of fetal immunecompetence in early pregnancy. In late gestational age, immunec

5. Toxicological parameters in silver catfish (Rhamdia quelen) exposed to cadmium / Parâmetros toxicológicos em jundiás (Rhamdia quelen) expostos ao cádmio
The aquatic ecosystems may be constantly receiving metals from industrial discharges and agriculture generated by anthropogenic activities. Thus, the organisms in the aquatic environment may be the target of these contaminants. The aim of this study was verify cadmium effects on silver catfish (Rhamdia quelen) metabolism. First was verified the lethal concen

6. CONCEPÇÃO, CONSTRUÇÃO E AVALIAÇÃO DE FOTORREATORES CATALISADOS NA DEGRADAÇÃO DE CARGA POLUENTE E AMOXICILINA EM EFLUENTE HOSPITALAR
The focus of this study was the application of advanced oxidation photoprocesses, heterogeneous photocatalysis and photo-Fenton, in the degradation of pollutant load and amoxicillin in wastewater from the University Hospital of Santa Maria (HUSM), evaluating the photoreactors performance in the degradation efficiency. In the hospital wastewater there is a wi

7. Efeito do 1,8-cineol sobre os parâmetros eletrofisiológicos das células nervosas do gânglio cervical superior de ratos / Effect of 1,8-cineol on electrophysiological parameters of nerve cells in the rat superior cervical ganglion
1,8-cineol is a terpene that constitutes many essential oils from medicinal folk plants. This compound presents many pharmacological activities as anti-inflammatory, antitumoral and gastroprotective. However it is difficult to find studies that relate the effects of both essential oils and its compounds in nervous system tissues. Since many of these oils and

8. Efeitos inibitórios de uma pista visual em tarefas de tempo de reação. / Inhibitory effects of a visual cue in reaction time tasks.
In reaction time tasks, a visual cue can trigger several processes and each of these processes can have either a facilitatory or inhibitory influence on different stages of target processing. It has been suggested that task set might modulate cuing effects. In the present study, we investigated the possible causes of inhibitory cueing effects. In experiments

9. Inhibitory effect of a visual prime stimulus in simple reaction time task. / Efeito inibidor de um estímulo precedente visual em uma tarefa de tempo de reação simples.
Studies about attention orienting that use Posner?s procedure have demonstrated two effects: an initial facilitation of responsivit when the target stimulus appears in the same location as the prime stimulus and a subsequent inhibition of this responsvity. In a previous work we could not find the early facilitatory effect of attention orienting in a simple r

10. Inhibition of return, gap effect and saccadic reaction time to a visual target
Simple manual reaction time (MRT) to a visual target (S2) is shortened when a non-informative cue (S1) is flashed at the S2 location shortly before the onset of S2 (early facilitation). Afterwards, MRT to S2 appearing at the S1 location is lengthened (inhibition of return - IOR). Similar results have been obtained for saccadic reaction time (SRT). Moreover,

11. Sodium pumps in the Malpighian tubule of Rhodnius sp.
Malpighian tubule of Rhodnius sp. express two sodium pumps: the classical ouabain-sensitive (Na+ + K+)ATPase and an ouabain-insensitive, furosemide-sensitive Na+-ATPase. In insects, 5-hydroxitryptamine is a diuretic hormone released during meals. It inhibits the (Na+ + K+)ATPase and Na+ -ATPase activities indicating that these enzymes are involved in fluid s

12. Reversal of cell determination in yeast meiosis: postcommitment arrest allows return to mitotic growth.
When yeast from the early stages of meiosis are transferred from sporulation to growth medium, they can reenter the mitotic cell cycle directly. In contrast, cells from later stages of meiosis (after the initiation of the first nuclear division) will complete meiosis and sporulation despite the shift to growth medium, a phenomenon known as "commitment to mei
