Although melatonin supplementation is known to influence numerous physiological functions, little is however known of its effects on pregnancy outcome. This study investigated the effects of melatonin supplementation on pregnancy outcome in Wistar-Kyoto (WKY) and Sprague-Dawley (SD) rats aged 12-13 weeks. Upon confirmation of proestrus, each female rat was housed ...

BACKGROUND/OBJECTIVES:Animal models have demonstrated that maternal overnutrition during pregnancy influences offspring adiposity. Few human studies of normal pregnancy have replicated these findings. We examined the association between child body mass index at age 5 years and maternal nutrient intake during pregnancy and 5 years postpartum.SUBJECTS/METHODS:Five-year-old children (n=585) and their mothers ...

Maternal plasma contains circulating cell-free (ccf) DNA fragments originating from both the mother and the placenta. The proportion derived from the placenta is known as the fetal fraction. When measured between 10 and 20 gestational weeks, the average fetal fraction in maternal plasma is 10 to 15%, but can range ...

Human and guinea pig fetuses are completely dependent on an adequate maternal vitamin C (vitC) intake. Shortage of micronutrients can have negative implications for fetal health and pregnancy outcome; however, knowledge of maternal vitC deficiency's impact on fetal development is sparse and reports of pregnancy outcome have been divergent. The ...

AIM: The aim of this study was to investigate whether full-term neonatal birthweight is decreasing or not. MATERIAL AND METHODS: Subjects were selected from the registration database of full-term singletons from a single local practitioner at two time-points, 1991 (n = 750) and 2011 (n = 442). Maternal age, parity, and smoking habits were ...

The transcription factor STAT5A is essential for two processes during mammary gland development. First, it controls the development of luminal progenitor cells from stem cells(1) and second, it has a role during pregnancy where it is required for alveologenesis(2) (,) (3) the production of clusters of luminal cells that synthesize ...

Maternal blood leptin levels are positively associated with adiposity. Recent studies suggest that leptin is also abundantly produced by the placenta and may function as a regulator of foetal growth. Our goal was to examine mid-pregnancy levels of leptin in maternal blood in relation to birthweight for gestational age (BW/GA) ...

Street drug use during pregnancy is detrimental to fetal development. Although the prevalence of wheeze is high in offspring of substance-abusing mothers, nothing is known about the role of street drug use during pregnancy in its development. We investigated the impact of maternal street drug use and distress during pregnancy ...

The relationship between maternal intrinsic factors and placental traits was investigated on three Southern Mediterranean breed of sheep; Cukurova Assaf (CA), Cukurova (C) and Cukurova Meat Sheep (CMS). The effect of parity and birth type were also considered in the study as a potential influencing factor. Our hypothesis was to ...

Pregnancy invokes a doubling of intestinal calcium absorption while lactation programs skeletal resorption to provide calcium to milk. Post-weaning bone formation restores the skeleton's bone mineral content (BMC), but the factors that regulate this are not established. We used Pth null mice to test whether parathyroid hormone (PTH) is required ...

Studies of treatment of postpartum endometritis in dairy cows indicate that prostaglandin (PGF2α) might result in similar outcomes as intrauterine antibiotics, but the effect might depend on the presence of a CL. The objective was to compare reproductive performance in cows with purulent vaginal discharge treated on the basis of ...

This study assessed the effect of feeding level on progesterone concentration in the caudal vena cava during early pregnancy in gilts. Twenty-four Landrace gilts were allocated to either a high (2.8±0.02) or a low (1.5±0.01kg day) feeding level at Day 0 of pregnancy. Serial blood samples were collected every 15min ...

A 37-yr-old Asian elephant (Elephas maximus) started parturition after 640 days of pregnancy but no fetal parts entered the birth canal. Despite veterinary intervention, the calf was not delivered. After 13 mo calving resumed and a full-term dead calf advanced into and lodged within the vagina. With standing xylazine tranquilization, ...

Reproductive management programs that synchronize ovulation can ovulate a smaller than normal follicle, potentially resulting in inadequate progesterone (P4) concentrations after artificial insemination (AI). Ovulation of the dominant follicle of the first follicular wave with human chorionic gonadotropin (hCG) treatment can produce an accessory corpus luteum and increase circulating P4 ...

Background/Objectives:Maternal fish consumption during pregnancy might influence the fetal immune system through anti-inflammatory effects of omega-3 fatty acids, and might affect the risks of childhood asthma and atopy. In Generation R, a prospective cohort study in the Netherlands, we examined the associations of first trimester fish consumption with childhood wheezing ...

Objectives were to compare circulating progesterone (P4) profile and pregnancies per AI (P/AI) of two commercial intravaginal P4 devices (PRID-Delta(®) vs CIDR(®)). In Experiment 1, ovariectomized dairy cows (PRID-Delta, n=6 vs CIDR, n=6) were sampled throughout 7 days to measure circulating P4. In Experiment 2 (PRID-Delta, n=399 vs CIDR, n=375), ...

The objectives of this study were to investigate heterogeneity in the variance of and the association between milk yield (MY) and pregnancy outcome (PO) in dairy cows, formally separating the within-herd (i.e., cow-level residual effects) from the between-herd (i.e., herd-level random effects) components. Based on a recently developed extension to ...

During pregnancy, changes occur in the maternal calcium homeostasis to fulfill fetal demand. We hypothesized that the fibroblast growth factor 23 (FGF23) system and Wnt signaling pathway are important for normal skeletal development in the offspring. Circulating α-klotho, FGF23, sclerostin, and 25-hydroxyvitamin D (25(OH)D) at the fetal and maternal sides ...

Recent recognition of the early onset and high prevalence of wasting (30%) and stunting (20%) among infants 0-5 months in India draws attention to the need to understand the causes and develop prevention strategies. Such growth failure has dire consequences in the short (increased mortality) and long-term (loss of human ...

One of the causes of poor fertility in high producing dairy cows is inadequate progesterone. Therefore, we determined the efficacy of an intravaginal insert containing 1.55 g of progesterone (PRID) given before and/or after timed AI (TAI) on ovarian response, plasma progesterone concentrations, pregnancy per AI (P/AI) and pregnancy losses. ...

Carcass and meat quality traits of 16 pregnant and 5 non-pregnant cows fed at 1.2 times maintenance and 16 pregnant and 6 non-pregnant fed ad libitum were evaluated. Pregnancy did not affect final body weight (FBW; P=0.0923), cold carcass yield (CCY; P=0.0513), longissimus muscle area (LMA; P=0.8260), rib fat thickness ...

Autism is a complex neuropsychiatric syndrome with a largely unknown etiology. Inflammation during pregnancy may represent a common pathway by which infections and other insults increase risk for the disorder. Hence, we investigated the association between early gestational C-reactive protein (CRP), an established inflammatory biomarker, prospectively assayed in maternal sera, ...

Abstract Measurement of amniotic fluid (AF) lactate concentration in complicated pregnancies may provide information on the extent of fetal acidemia. However, normalisation for AF volume may be necessary by calculating the lactate:creatinine (L:C) ratio. We measured these AF parameters and compared them to arterial cord blood lactate in 28 term ...

INTRODUCTION: The weight of the placenta is a crude but useful proxy for its function in vivo. Accordingly extremes of placental weight are associated with adverse pregnancy outcomes while even normal variations in placental size may impact lifelong health. Centile charts of placental weight for gestational age and gender are used ...
