DB Cox, Auteur ; RA Owens, Auteur ; Pe Hartmann, Auteur |In women, the concentration of prolactin in the plasma increases in response to nipple stimulation. This response has led to the assumption that prolactin influences the rate of milk synthesis. To investigate this hypothesis we have measured 24 [...]Article : texte imprimé
Pe Hartmann, Auteur ; RA Owens, Auteur ; JC Kent, Auteur |We have developed a computerized breast measurement system that can quantitate both long-term (lactation cycle) and short-term (between breastfeedings) changes in breast volume. The increase in breast volume during pregnancy was not related to m[...]Article : texte imprimé
DB Cox, Auteur ; JC Kent, Auteur ; Pe Hartmann ; RA Owens, Auteur |Breast volume and morphology of eight subjects were measured before conception and at intervals throughout pregnancy until 1 month of lactation. Breast volume before conception ranged from 293 to 964 ml. At the end of pregnancy the volume of bre[...]Article : texte imprimé
JC Kent, Auteur ; L Mitoulas, Auteur ; Pe Hartmann, Auteur |Quantitative measurements were made of relative breast volume and milk production from 1 month of lactation until 3 months after weaning, and the storage capacity of the breasts was calculated. The increase in breast tissue volume from before co[...]Article : texte imprimé
SE Daly, Auteur ; JC Kent, Auteur ; Pe Hartmann, Auteur |The effect of the temporal spacing and degree of milk removal by either expression or breastfeed on short-term (hour to hour) rates of milk synthesis was investigated. For four expressing mothers (three of whom had given birth prematurely), the [...]Article : texte imprimé
Pe Hartmann, Auteur ; JL Sherriff, Auteur |Apart from the metabolic differences between species (ruminant vs. nonruminant), there are other important physiologic differences in both the energy requirements for lactation and in the control of milk production between dairy cows and women. [...]Article : document cartographique imprimé
DT Ramsay, Auteur ; JC Kent ; L Mitoulas, Auteur ; DA Doherty ; Pe Hartmann ; MD Cregan, Auteur |Currently there is no simple method available to assess milk ejection and breast milk flow in lactating women in both the clinical and research setting. The authors hypothesize that changes in milk flow rate are associated with milk ejection and[...]document électronique
DB Cox, Auteur ; RA Owens, Auteur ; Pe Hartmann, Auteur | 1998This paper describes the conception of the volume measurement system and its evolution. We highlight the principle findings from studies using the CBM system, and explain how they relate to the understanding of breast physiology.Article : texte imprimé
SE Daly, Auteur ; JC Kent, Auteur ; Pe Hartmann, Auteur |The feasibility of using sequential breast volume measurements as a method of studying short-term rates of milk synthesis in women has been established. We have developed a rapid Computerized Breast Measurement system for the determination of br[...]Article : texte imprimé
SE Daly, Auteur ; RA Owens, Auteur ; Pe Hartmann, Auteur |We studied how short-term milk synthesis responds to milk removal by observing breast volume before and after each breastfeed over 24 h periods within the homes of seven lactating mothers, using the Computerized Breast Measurement system. Short-[...]Article : texte imprimé
DT Ramsay, Auteur ; JC Kent, Auteur ; Pe Hartmann, Auteur |OBJECTIVE: Currently, the methods for assessing milk ejection in women include serial sampling of plasma oxytocin and measurement of intraductal pressure, both of which are invasive and may induce stress. We hypothesized that milk ejection would[...]
