Association of Maternal Secretor Status and Human Milk Oligosaccharides With Milk Microbiota: An Observational Pilot Study

2019

Background and Objectives: Breast milk contains several bioactive factors including oligosaccharides (HMO) and microbes that shape the infant gut microbiota. HMO profile is determined by secretor status, however their influence on milk microbiota is still uncovered. This study is aimed to determine the impact of the FUT2 genotype on the milk microbiota during the first month of lactation and the association with HMO. Methods: Milk microbiota from 25 healthy lactating women was determined by quantitative PCR and 16S gene pyrosequencing. Secretor genotype was obtained by PCR-RFLPs and by HMO identification and quantification. Results: The most abundant bacteria were Staphylococcus and Strepto…

Relationships between dietary factors and milk urea nitrogen level in goats grazing herbaceous pasture

2008

This investigation aimed to individuate the dietary factors affecting the milk urea nitrogen (MUN) concentration in goats grazing herbaceous pasture and, particularly, to verify the relationship linking the diet crude protein (CP) content to MUN. A total of 205 individual observations regarding dietary and milk variables of 37 Girgentana goats involved in two experiments were used. Goats, averaging 154±14 days in milk and 38.1±5.4 kg of live weight, grazed on swards and received 500 g/d of barley meal. Sward biomass, herbage selected by goats and individual milk yield were measured and sampled weekly. The herbage intake and diet digestibility were estimated by the n-alkane met…

Effect of beta-lactoglobulin polymorphism on milk-related traits of dairy ewes analysed by a repeated measures design.

2000

Among specific genes that may affect economically important traits in sheep, the β-lactoglobulin (LGB) locus has been extensively studied. Polymorphism has been detected in several breeds, but studies of the effect of LGB alleles on milk production traits have given conflicting results. Some found that LGB polymorphism significantly affects milk yield (Bolla et al. 1989; Herget et al. 1995; Fraghì et al. 1996), fat and protein content (Garzon & Martínez 1992; Giaccone et al. 1997; Kukovics et al. 1998), only fat content (Pirisi et al. 1998) and cheese yield and composition (Di Stasio et al. 1997; Rampilli et al. 1997). However, other studies failed to detect any effect of the gene on mi…

La Balia (1999). Una visión de las nodrizas en los albores del Siglo XX

2012

[ES] La película La Balia (1999) nos permite reflexionar sobre la importancia histórica de la figura de las nodrizas en el período entre los siglos XIX y XX. Una figura normalizada en la época y que permitió por una parte a las mujeres donantes tener un papel fundamental en el mantenimiento de sus familias, y por la otra permitió la superviviencia de niños gracias a la alimentación con leche materna. [EN] The film La Balia/ The Nanny (1999) allows us to reflect on the historical significance of the figure of the wet nurses in the period between the nineteenth and twentieth centuries. A standardized set the time and allowed for some women donors have a key role in the maintenance of their fa…

Social Vision on Wet Nurses in the [Spanish] Newspaper “La Vanguardia” (1881-1908)

2017

Históricamente ha habido situaciones y momentos en que las madres han delegado el proceso de lactancia en nodrizas. En el siglo XIX las nodrizas fueron representadas en la prensa española reproduciendo los esquemas del modelo social androcéntrico imperante. Se pretende describir y categorizar la visión de la nodriza reflejada en la prensa española mediante el análisis de contenido de las fuentes periodísticas de este período. La conclusión alcanzada han sido que la prensa refleja la importancia social de la nodriza como un elemento normalizado en la sociedad con un papel fundamental en los aspectos demográficos de la sociedad, estableciendo una visión dual en función del grupo social al que…

Acute stress may induce ovulation in women

2010

Abstract Background This study aims to gather information either supporting or rejecting the hypothesis that acute stress may induce ovulation in women. The formulation of this hypothesis is based on 2 facts: 1) estrogen-primed postmenopausal or ovariectomized women display an adrenal-progesterone-induced ovulatory-like luteinizing hormone (LH) surge in response to exogenous adrenocorticotropic hormone (ACTH) administration; and 2) women display multiple follicular waves during an interovulatory interval, and likely during pregnancy and lactation. Thus, acute stress may induce ovulation in women displaying appropriate serum levels of estradiol and one or more follicles large enough to respo…

Lipid content and essential fatty acid (EFA) composition of mature Congolese breast milk are influenced by mothers' nutritional status: Impact on inf…

1998

To measure the lipid content and the fatty acid (FA) composition of breast milk as part of a nutritional survey of the essential fatty acid (EFA) status of 5 months old Congolese infants.Cross sectional nutrition survey.A suburban district of Brazzaville (capital of the Congo).A random sample of nursing mothers and their 5 months old infants (n = 102). Data collection procedures: The mothers were questioned on their socio-economic status, dietary habits, and their body mass index (BMI) was measured. Breast milk samples were collected from each mother. Milk lipid content and fatty acid composition were determined.Compared with milk from various countries, Congolese women's mature breast milk…

Corrigendum: Wired for motherhood: induction of maternal care but not maternal aggression in virgin female CD1 mice

2015

Virgin adult female mice display nearly spontaneous maternal care towards foster pups after a short period of sensitization. This indicates that maternal care is triggered by sensory stimulation provided by the pups and that its onset is largely independent on the physiological events related to gestation, parturition and lactation. Conversely, the factors influencing maternal aggression are poorly understood. In this study, we sought to characterize two models of maternal sensitization in the outbred CD1 strain. To do so, a group of virgin females (godmothers) were exposed to continuous cohabitation with a lactating dam and their pups from the moment of parturition, whereas a second group …

The development of oral feeding skills in infants.

2012

Appropriate nutritional intake is a major component of growth in infants. Interests in nutrition customarily have been centered on the types of nutrients and caloric intake offered, for example, the benefits of mother's milk over that of formula, presence/absence of growth factors, and potential advantages provided by probiotics early in life [1, 2]. An important component of infant nutrition that has been overlooked until recently is the ability of infants to take their nutrients by mouth safely and successfully. As the majority of healthy term newborns are readily taken to the breast or bottle soon after birth, the ability to feed by mouth generally does not raise concern. However, over t…
