Vitamin D status and requirements during pregnancy and lactation
Vitamin D deficiency during pregnancy, lactation, and early infancy has been widely reported. Current understanding of vitamin D metabolism during pregnancy and lactation is incomplete, and to date, experimental data to support vitamin D requirements for these life stages are scarce. There is a …

Hypothalamic control of energy rheostasis during metabolic challenges, pregnancy, and lactation
… rely on the ability of their brain to detect and respond to energetic demands changes, yet the neural circuits that allow adaptation to energy imbalance are not fully understood. The melanocortin-3 receptor (MC3R) has been shown to play an important role in energy rheostasis, with global …

Autophagy: activation, function and regulation by a protein restricted diet during pregnancy and lactation
… numerous diseases including obesity, diabetes and cardiovascular disease, both in the mother and offspring. Recent intensive research efforts have focused on the mechanisms behind the effects of a maternal low protein diet on diseases in offspring. However, thus far, the mechanisms behind the …

Natural Health Products (NHPs) in Pregnancy and Lactation: A Review of the Landscape and Blueprint for Change
… Based on the perceived risk to newborns and pregnancy outcomes associated with certain drugs, women may be hesitant to prescribe and take drugs during pregnancy. In cases like these, pregnant women may seek treatment using natural health products (NHPs) as alternatives to drugs. …

Purification of Calmodulin and Quantification of Its Levels in Mammary Tissue and Isolated Cells During Pregnancy and Lactation (Acini, Secretory, Myoepithelial)
… Calmodulin was purified by heat treatment and sequential anion exchange and gel exclusion chromatographies. The molecular weight of the purified protein was estimated by gel electrophoresis to be 18,000 daltons. The purified protein produced a 10-fold stimulation of the activity of bovine …

Moralizing Substance Use In Maternal-Child Symbiosis: An Emergent Fit Dimensional Analysis
… However, they commonly moralize substance use and other similarly stigmatized actions during pregnancy and lactation. As a result, pregnant or lactating persons and their infants experience suboptimal health outcomes. Improving health outcomes in this population necessitates understanding how …

Investigation of the role of CUZD1-STAT5 signaling in mammary gland development and breast cancer
In the mammary gland, genetic circuits controlled by the hormones, estrogen, progesterone and prolactin (PRL), act in concert with pathways regulated by the epidermal growth factor (EGF) family to control the growth and morphogenesis of this tissue during puberty, pregnancy and lactation. However, …

Characterization of the IGF system in food-restricted pregnant and lactating rats: Role of IGF-I in nutrient partitioning
Metabolic and behavioral mechanisms have been implicated in the development of adaptive strategies to suboptimal nutrition. However, very little is known about the underlying endocrine mechanisms involved in this adaptation. To investigate the role of the IGF-I in adaptation to dietary restriction, …

Factors affecting the activity patterns of Myotis tricolor (Chiroptera: Vespertilionidae)
… during each reproductive period: early pregnancy, late pregnancy and lactation. Times at which bats entered and exited the cave were recorded, as was the temperature, moon-phase, cloud cover, wind speed, rainfall and insect abundance. These data were used to calculate emergence time, …

The Role of Prolactin in CCL28 Regulation
… that produce IgA enter the mammary tissue during lactation and secrete IgA into the milk. During pregnancy, the mammary tissue expresses high levels of chemokines, molecules that allow lymphocytes to selectively home to specific tissues. The chemokine CCL28 has been shown to be upregulated during …

Maternal High Fat Feeding: Impact of Female Offspring Body Composition and Bone Health
… consumption in rodents alters body composition and weakens bones. Whether female offspring of mothers consuming a HFD are similarly affected at weaning and early adulthood is unclear. This research determined whether maternal HFD contributes to long-lasting alterations in body composition and …

The Impact of Maternal Methyl-Donor Nutrient Supplementation on Vitamin D Status and Inflammation among Adult Offspring
Maternal overweight and obesity is associated with higher risks of childhood obesity. Low vitamin D (VD) status is often observed among overweight and obese (OWO) individuals, enhancing their risk for the development of secondary complications, such as inflammatory bowel diseases, cardiovascular …

Role of IGF-II, PRL, and FABPs in the Breast Cancer Disparity among AA Women
… with more advanced states of breast cancer and have lower survival rates than Caucasian-Americans (CA). Epidemiological data have shown that pregnancy and lactation at an early age in humans reduce the risk of breast cancer. Studies in mice and rats have shown that lactation stimulates the …

Molecular determinants of mammary differentiation and breast cancer progression
… of multiple cell lineages. Development and maintenance of this tissue are carefully orchestrated by balancing stem and progenitor cell self-renewal and differentiation. The mammary epithelium must also endure the successive regenerative cycles of pregnancy and lactation. Therefore, it is …

Seasonal variation in the natality, mortality, and nutrition of the pine vole in two orchard types
… were collected for one year in a maintained and an abandoned orchard. Higher densities of voles were indicated in the maintained orchard. Estimates of mortality were lower and reproduction was higher in the maintained orchard. Net reproductive rates indicated a stable or increasing population …

Perinatal essential fatty acid deficiency in mice: effects on metabolism and behaviour
Maternal nutritional status during pregnancy and lactation influences the health of the adult offspring and an adequate supply of essential fatty acids is important for foetal and postnatal growth and development. The overall aim of this thesis was to study short- and long-term effects of perinatal …

The Evolution of Extended Sexual Receptivity in Chimpanzees: Variation, Male-Female Associations, and Hormonal Correlates
<p>Sexual conflict occurs when female and male fitness interests diverge. In a social system characterized by aggressive sexual coercion and the risk of infanticide, female chimpanzees (Pan troglodytes) respond to this conflict by exhibiting an exaggerated sexual swelling that advertises sexual …

NADPH-d staining in the supraoptic and paraventricular nuclei increases in late pregnant and lactating rats and is influenced by ovarian steroids and central oxytocin levels
… synthase is increased in the supraoptic (SON) and paraventricular (PVN) nuclei in late pregnancy. This work was extended to investigate whether increases in staining were evident at other times during pregnancy and lactation. The number of cells in the SON and PVN that stained for NADPH-d in …
