As a model system to study the elasticity of bottle-brush polymers, we here introduce self-assembled DNA bottle brushes, consisting of a DNA main chain that can be very long and still of precisely defined length, and precisely monodisperse polypeptide side chains that are physically bound to the DNA main chains. Polypeptide side chains have a diblock architecture, where one block is a small arc...

This study is concerned with differences between breast-fed and bottle-fed infants in plasma and red blood cell (RBC)-levels and pattern of tocopherol analogues. Tocopherol levels were determined by High-Performance Liquid Chromatography (HPLC). The results were as follows: 1. In breast-fed infants the plasma contained larger amounts of the alpha and smaller amounts of the gamma form of tocophe...

A N intelligent, primiparous woman, who was confined in hospital, delivered herself of a healthy male infant weighing 8k lb. at birth. The mother's nipples were inverted and for this reason her lactation was suppressed at the outset, the baby being fed on reconstituted, half-cream, dried milk from an upright feeding bottle. They were discharged home on the tenth day, the infant having regained ...

This study evaluated the effect of breast- and bottle-feeding duration on the age of pacifier use persistence. Questionnaires (n = 723) with information on nutritive and nonnutritive sucking habits of children aged 3-6 years were assessed. The sample was divided according to breastfeeding duration: G1 - non-breastfed, G2 - up to 3 months, G3 - discontinued between 4 and 6 months, G4 - discontin...

OBJECTIVE To better understand the mechanisms behind breastfeeding and childhood obesity, we assessed the association of weight gain with the mode of milk delivery aside from the type of milk given to infants. DESIGN A longitudinal study of infants followed up from birth to age 1 year. Multilevel analyses were conducted to estimate infant weight gain by type of milk and feeding mode. SETTIN...

Recycling used plastic bottles is a significant step towards environmental protection and land pollution. Lifestyle changes in developing countries such as South Korea have substantially impacted the increase use rate of waste year by year. Plastic various types usually varied recycling values. In most countries, human labor to manually categorize handle recyclable waste. This study aims provid...

BACKGROUND Behavioral mechanisms that contribute to the association between breastfeeding and reduced obesity risk are poorly understood. The purpose of this study was to evaluate the hypothesis that feeding human milk from the breast (direct breastfeeding) has a more optimal association with subsequent child appetite regulation behaviors and growth, when compared to bottle-feeding. METHODS C...

If a fullerene is defined as a finite trivalent graph made up solely of pentagons and hexagons, embedding in only four surfaces is possible: the sphere, torus, Klein bottle, and projective (elliptic) plane. The usual spherical fullerenes have 12 pentagons; elliptic fullerenes, 6; and toroidal and Klein-bottle fullerenes, none. Klein-bottle and elliptic fullerenes are the antipodal quotients of ...
