The BACTEC 16B resin medium was developed to detect bacteremia in patients receiving antimicrobial therapy. Over a 9-month period, we compared the efficacy of the BACTEC 16B bottle to the conventional aerobic BACTEC 6B bottle. Of a total of 1,524 sets of blood cultures, 79 yielded presumed pathogens. Of these 79 sets, 42 (53.2%) were positive in both the 16B and 6B bottles, 23 (29.1%) were posi...

The label on a bottle of pills says “Take one half pill daily.” A natural way to proceed is as follows: Every day, remove a pill from the bottle at random. If it is a whole pill, break it in half, take one half, and return the other half to the bottle; if it is a half pill, take it. We analyze the history of such a pill bottle.

BACKGROUND Few studies have provided evidence to verify that bottle-feeding has negative effects on breastfeeding. There is insufficient evidence to support the practice of cup-feeding to supplement breastfeeding. However, it has been applied as a substitute for bottle-feeding to promote breastfeeding. The aims of this study were to explore the differences in infant sucking competence, infant s...

Oxygen saturation is lower during bottle feeding than during breastfeeding in preterm infants. Our objective was to compare two different bottle systems in healthy preterm infants before discharge in terms of SpO(2) and oral feeding efficiency (rate of milk intake). Infants without supplement oxygen needs were evaluated twice on the same day during two consecutive feeds, by the same nurse. Infa...

A study comparing the recovery of microorganisms from a transiently vented biphasic brain heart infusion medium bottle and a vacuum bottle containing tryptic soy broth demonstrated that growth was initially detected on the slant of the biphasic bottle or on a routine subculture of either broth in nearly 50% of instances. All organisms were isolated equally well in both bottles, with the excepti...

BACKGROUND Childhood iron deficiency is associated with behavioral and cognitive delays. Few studies have explored the relationship between prolonged bottle-feeding and iron-deficiency anemia among toddlers. OBJECTIVE To examine the association between prolonged bottle-feeding and iron deficiency in a nationally representative sample of children ages 1 to 3 years. DESIGN AND METHODS The Nat...

The appearance of bottle cells at the dorsal vegetal/marginal boundary of Xenopus embryos marks the onset of blastopore formation. The conditions leading to this epithelial activity were investigated by inducing bottle cells ectopically in the animal region with VegT or different members of the transforming growth factor (TGF)-beta family. Morphological studies on the ectopic bottle cells indic...

BACKGROUND There is very little evidence of the similarity of the mechanics of maternal and bottle feeding. We assessed the mechanics of sucking in exclusive breastfeeding, exclusive bottle feeding, and mixed feeding. The hypothesis established was that physiological pattern for suckling movements differ depending on the type of feeding. According to this hypothesis, babies with breastfeeding h...

In 1981 Walter Rudin exhibited a totally real embedding of the Klein bottle into C2. We show that the polynomially convex hull of Rudin’s Klein bottle contains an open subset of C2. We also describe another totally real Klein bottle in C2 whose hull has topological dimension equal to three.
