BACKGROUND When breastfeeding is difficult or impossible during the neonatal period, an analysis of muscle activity can help determine the best method for substituting it to promote the child's development. The aim of this study was to analyze the electrical activity of the masseter muscle using surface electromyography during suction in term newborns by comparing breastfeeding, bottle and cup ...

Babies may need supplementation due to difficulty breastfeeding. Others must be fed by alternative feeding methods because they are separated from mothers who have returned to employment or school. Recognizing that mothers and caregivers are often not comfortable using other alternative feeding devices, the author endeavored to develop a method of bottle-feeding that would meet the needs of the...

A simple method is described for treating 250-ml glass Wheaton bottles with insecticide, and using them as test chambers for detecting insecticide resistance in mosquito and sandfly populations. The methods for treating bottles, obtaining baseline data, and applying this technique to insects from the field are described. Sample data are presented from tests run on different vector species using...

Although an important role for the amygdala in taste aversion learning has been suggested by work in a number of laboratories, results have been inconsistent and interpretations varied. The present series of studies reevaluated the role of the amygdala in taste aversion learning by examining the extent to which conditioning methods, testing methods and lesioning methods, influence whether amygd...

A multisurface glass roller bottle has been constructed for the growth of animal cells in culture. This bottle contains five concentrically placed glass cylinders that provide additional surfaces for the growth of animal cells. The bottle occupies the same space as a standard roller bottle, but it contains nine times the surface area of a standard bottle. L and HeLa cells can be grown in the bo...

The current BacT/Alert standard aerobic (VA) blood culture bottle was redesigned and designated a nonvented aerobic (NVA) culture bottle; this bottle does not require venting. A total of 3,873 sets of blood samples for culture were obtained from adult patients with suspected bacteremia or fungemia. The NVA bottle showed performance equivalent to that of the VA bottle for recovery and speed of d...

Development of a new perfusion culture system for the production of attenuated poliomyelitis virus in cultures of diploid cells is described. The growth characteristics of the diploid cells (MRC-5) were found to be normal in the perfused system. Procedures for the routine production of cell cultures at twice the cell density of stationary bottle cultures were established. The yield of virus (Ls...

BACKGROUND AND AIM: Sucking of some types of a pacifier may be a risk factor for mal-development of orofacial structures and malocclusion. This study assessed the prevalence of using of different types of pacifier and bottle nipple among 1-24 months old children in Kerman, Iran.METHODS: In this cross-sectional study, a total of 300 mothers interviewed at 20 specialized private pediatric offices...
