1. Effect of the 5-HT4 receptor and serotonin transporter on visceral hypersensitivity in rats
Visceral hypersensitivity plays an important role in motor and sensory abnormalities associated with irritable bowel syndrome, but the underlying mechanisms are not fully understood. The present study was designed to evaluate the expression of the 5-HT4 receptor and the serotonin transporter (SERT) as well as their roles in chronic visceral hypersensitivity

2. Efeitos de arqueamento em aterros sobre solo estaqueado / Soil arching effects due to earth fills supported by piled foundations
Na atualidade, a construção de obras sobre solos de baixa capacidade de suporte é um problema que os engenheiros devem enfrentar cada vez com mais freqüência, e tentar encontrar soluções viáveis e seguras. Em Brasília fez-se necessária a elaboração de um projeto de melhoramento da interseção sobre a DF-003, resultando na execução de um viadut

3. Estudo do fluxo de material fragmentado na mineração subterrânea, com o uso de modelos físicos
The main objective of this work was the study of gravity flow in excavations, mainly ore passes, in underground mining, by use of physical models. At review of literature it is presented terminology, flow properties of bulk materials, laws of gravity flow, flow design, flow patterns, flow phenomena, such as arching and rat holing, issues of security at work

4. Physical modeling of buried pipes subjected to localized loss of support or elevation / Modelagem física de condutos enterrados sujeitos a perda de apoio ou elevação localizada
Este trabalho apresenta um estudo experimental sobre o comportamento de dutos enterrados sofrendo perda de apoio ou elevação em uma determinada região ao longo do comprimento. Foram realizados ensaios com modelos físicos compostos por um maciço de areia pura contendo um tubo repousando sobre um alçapão localizado no centro do vão. A pesquisa envolveu

5. Arched gonadal arteries in the South African negro.
The frequency with which the gonadal arteries follow a recurrent course, upwards and arching over the renal veins before descending to the gonads, is recorded for the South African Negro. The gonadal arteries follow such a course on the left side in 17, 2% and on the right side in 22% of cases. This incidence for arched left sided arteries is comparable to t

6. Persistence of third aortic arch with fourth aortic arch agenesis.
This report describes a case in which a persistent third aortic arch connection partly palliated interruption of the aortic arch. The malformation occurred without other cardiovascular abnormality in a newborn infant in whom the principal diagnostic clinical finding was the absence of all peripheral pulses except for those of the right brachial and carotid a

7. Echocardiographic identification of aorta and main pulmonary artery in complete transposition.
No completely reliable echocardiographic technique has been described for the separate identification of the aorta and main pulmonary artery in complete transposition of the great arteries. A mechanical wide-angle (60 degrees) sector scanner has been applied to this problem in 17 infants and young children, including 8 newborns before angiocardiography. In a

8. Abnormal gait sequence in locomotion after atropine treatment of catecholamine-deficient akinetic rats.
Excessive, abnormal locomotion occurs after a high dose (25-50 mg/kg) of atropine sulfate to rats already akinetic due to catecholamine deficiency from intraventricular administration of 6-hydroxydopamine. This abnormal locomotion involves an abnormal gait sequence [right (R) hindleg (H), left (L) foreleg (F), LH, RF] instead of the normal gait sequence (RH,

9. Cor triatriatum sinistrum. Diagnostic features on cross sectional echocardiography.
M mode and cross sectional echocardiography was carried out in three cases of cor triatriatum sinistrum (two infants and one adult). In two cases a peculiar double arch appearance, not previously reported, was found. All three cases were referred for surgery without cardiac catheterisation, and the diagnosis proved to be correct. The characteristic echocardi
