Measurement of the pressure applied to the anterior region of the palate and incisor region of the mandible during thumb-sucking was carried out 3 female children. A polyethylene bag embedded with a high-sensitivity small pressure sensor was fixed on the ventral side of the thumb so that the baroreceptor could be interposed between the thumb and palate during thumb-sucking. The children were al...

The pioneering work of Simon Maddrell established that the rapid postprandial diuresis of the haematophagous insect Rhodnius prolixus is controlled by a diuretic hormone and demonstrated the role of the Malpighian tubules in meeting the volumic, osmotic and ionic challenges posed by an enormous blood meal. A number of diuretic and antidiuretic hormones that control secretion of primary urine by...

AIMS To assess the effect of the type of feeding and non-nutritive sucking activity on occlusion in deciduous dentition. METHODS Retrospective study of 1130 preschool children (3-5 years of age) who had detailed infant feeding and non-nutritive sucking activity history collected by a structured questionnaire. They all had an oral examination by a dentist, blinded to different variables evalua...

This study assessed the effect of an oral stimulation program on the maturation of sucking skills of preterm infants. Thirty-two preterm infants (13 males, 19 females), appropriate size for gestational age (gestational age at birth 28 wks, SD 1.2wks; birthweight 1002g, SD 251g), were randomly placed into experimental and control groups. The experimental group received a daily 15-minute oral sti...

This article describes an innovative method for regulating populations of blood-sucking Diptera that parasitize cows. relates to the field agriculture, namely means protecting farm animals from insect bites, and can be used protect ectoparasites during period their grazing. To produce these products, polymer was treated with impregnating solution containing pyrethroid (2-26% by weight untreated...
