To develop a technique suitable for measuring NaCl taste thresholds in genetic studies, we conducted a series of experiments with outbred CD-1 mice using conditioned taste aversion (CTA) and two-bottle preference tests. In Experiment 1, we compared conditioning procedures involving either oral self-administration of LiCl or pairing NaCl intake with LiCl injections and found that thresholds were...

OBJECTIVES Bottle-feeding has been suggested to increase the risk of pyloric stenosis (PS). However, large population-based studies are needed. We examined the effect of bottle-feeding during the first 4 months after birth, by using detailed data about the timing of first exposure to bottle-feeding and extensive confounder information. METHODS We performed a large population-based cohort stud...

Background: Olfaction is a highly salient sensory modality in early human life. Neonates show keen olfactory sensitivity and hedonic responsiveness. However, little is known about hedonic olfactory responsiveness between the neonatal period and 2 years of age. In an attempt to fill this gap, this longitudinal follow-up study aimed at investigating hedonic responses to food odours in infants dur...

Grantham-McGregor, S. M., and Back, E. H. (1970). Archives of Disease in Childhood, 45, 404. Breast feeding in Kingston, Jamaica. A longitudinal study was carried out on 300 Kingston infants born at the University Hospital of the West Indies. The method of milk feeding and the reasons given by the mothers for beginning bottle feeding were recorded. Other factors influencing the incidence of bre...

BACKGROUND The purpose of this study is to evaluate the number of eyedrops available per bottle of a variety of commonly prescribed glaucoma medications. METHODS Six bottles of each glaucoma medication were tested: three each in the vertical and horizontal orientations. Bottles were housed in a customized force gauge apparatus designed to mimic ballpoint fingertip contact with a bottle. At a ...

This paper proposes a method for interactive recognition of household objects by a robot using proprioceptive feedback. In our experiments, the robot observed the changes in its proprioceptive stream while performing five exploratory behaviors (lift, shake, drop, crush, and push) on 50 common household objects (e.g., bottles, cans, balls, toys, etc.). Specifically, the robot used its own joint ...

In a comparison of 1,368 positive blood cultures, a vented Roche Septi-Chek (V-RSC) blood culture bottle was superior to an unvented tryptic soy broth-containing bottle (Difco) for the recovery of all aerobic and facultatively anaerobic microorganisms. Anaerobic bacteria were recovered more frequently and earlier in the unvented tryptic soy broth-containing bottle. A separate comparison of 529 ...

dinoflagellates, which he sampled with a bottle of his design, closed by a messenger sent down the wire. The bottle was suspended from the end of the wire, so only a single sample could be obtained on each cast. The next sample bottle associated with Scripps was developed by Winfred E. Allen, a student of Kofoid’s and an assistant professor at Scripps from 1919–1943 (Figure 2). Allen gathered a...

introduction: severe early childhood caries is the presence of smooth-surface caries in children younger than three years of age. this rampant form of dental caries exerts a negative impact on the quality of life of both the child and the family .the purpose of this study was to investigate the risk factors for severe early childhood caries (s-ecc) among 2-3 year-old children in rasht. material...
