Abstract:
Despite an increase of circulatory volume and of renin-angiotensin-aldosterone system (RAAS) activity, pregnancy is paradoxically accompanied by a decrease in blood pressure. We have reported that the decrease in blood pressure was maintained in pregnant rats despite overactivation of RAAS following reduction in sodium intake. The purpose of this study was to evaluate the impact of the opposite condition, e.g., decreased activation of RAAS during pregnancy in the rat. To do so, 0.9% or 1.8% NaCl in drinking water was given to nonpregnant and pregnant Sprague-Dawley rats for 7 days (last week o

Abstract:
The (pro)renin receptor (PRR) is a new component of the renin-angiotensin-aldosterone system (RAAS) and regulates renin activity. The objective of the present study was to test potential roles of the renal PRR and intrarenal RAAS in the physiological status of late pregnancy. Late pregnant Sprague-Dawley rats were studied 19–21 days after sperm was observed in vaginal smears. Experiments were performed using age-matched virgin rats and late pregnant rats treated with the specific PRR inhibitor PRO20 (700 μg·kg−1·day−1 sc for 14 days, 3 times/day for every 8 h) or vehicle.

Abstract Leptin concentrations increase during pregnancy, but this does not prevent the pregnancy-induced increase in food intake, suggesting a state of leptin resistance. This study investigated the response to intracerebroventricular leptin administration in pregnant rats. After fasting, nonpregnant, d-7 and d-14 pregnant rats received leptin (4 μg) or vehicle, then food intake was measured. Serial blood samples were collected in another group of rats to determine plasma leptin concentrations. Further groups of d-14 pregnant and nonpregnant rats were killed after leptin or vehicle treatment,

Abstract:
Lowering and increasing sodium intake in pregnant rats evoke opposite changes in renin–angiotensin–aldosterone system (RAAS) activity and are associated with alterations of blood volume expansion. As augmented uterine blood flow during gestation is linked to increased circulatory volume, we wanted to determine if low- and high-sodium intakes affect the mechanical properties and angiotensin II (AngII) responses of the uterine vasculature. Non-pregnant and pregnant rats received a normal sodium (0.22% Na+) diet. On the 15th day of gestation some animals were moved to a low-sodium (0.03%) diet, w

Endogenous opioid regulation of neurohypophysial and hypothalamo-pituitary-adrenal (HPA) axis hormone secretion in response to forced swimming (90 s in deep water at 19 degrees C) was investigated in virgin and 21-day-pregnant rats. There was no difference in basal plasma oxytocin concentrations between pregnant and virgin rats, but the opioid antagonist, naloxone, increased basal oxytocin secretion in the pregnant rats. Forced swimming increased oxytocin secretion similarly in pregnant and virgin rats, and this response was enhanced by naloxone. In pregnant rats naloxone had a greater effect

During pregnancy, there is a marked plasma volume expansion due to renal sodium retention. Pregnant rats exhibit a blunted response to natriuretic stimuli that signal via cGMP, and expression and activity of the cGMP phosphodiesterase PDE-5 are upregulated in the inner medullary collecting duct during pregnancy. Here, we tested the hypothesis that the natriuretic response to a cAMP agonist, dopamine, is maintained during pregnancy.

Abstract:
During normal pregnancy, a gradual plasma volume expansion (VE) occurs and reaches a maximum level at late term. Pressure natriuresis and renal interstitial hydrostatic pressure (RIHP) responses are attenuated in pregnant rats. Also, basal RIHP is lower in pregnant rats, suggesting an increase in renal interstitial compliance during pregnancy. This adaptation may contribute to the increase in plasma volume that is required for a normal pregnancy, because increases in RIHP have been consistently shown to produce natriuresis and diuresis.

Abstract:
Under normal circumstances, prolactin regulates its own release via a short-loop negative feedback mechanism in which prolactin, secreted from lactotrophs situated within the anterior pituitary gland, stimulates dopaminergic neurons in the hypothalamus to release dopamine into portal blood circulation. Dopamine, in turn, inhibits lactotroph activity. A change in this regulation of prolactin secretion is seen during late pregnancy where tuberoinfundibular dopaminergic (TIDA) neurons no longer respond to elevated levels of placental lactogen (PL), a lactogen structurally and functionally similar

Abstract:
Hypertension and pregnancy are both accompanied by increases in sympathetic nerve activity. This has been attributed in part, to changes in the neurochemistry of the hypothalamic paraventricular nucleus (PVN). In hypertension, physiological studies have revealed that decreases in GABAergic inhibition and increases in glutamatergic excitation within the PVN contribute to this sympathoexcitation. In late-term pregnancy however, the sympathoexcitation appears to be mediated by decreases in GABAergic inhibition, with no glutamatergic contribution.

Cardiovascular system (CVS) adaptation during pregnancy involves numerous hemodynamic changes and remodeling of peripheral and central regulatory mechanisms. A decrease in blood pressure (BP) during pregnancy activates the baroreflex, leading to an increase in sympathetic tone and the synthesis and secretion of vasopressin (VP). It is well-established that VP plays a critical role in the adaptation to normotensive pregnancy, as well as in the development of primary hypertension.

Abstract:
This study evaluates the receipt of influenza and pertussis vaccines among pregnant women from 2012-2018 in the U.S. using data from the Pregnancy Risk Assessment Monitoring System. The data showed the percentage of influenza vaccination among rural pregnant women was lower than their urban counterparts with significant differences in certain subgroups. The data, however, for pertussis vaccination in pregnant women across the urban-rural continuum showed similar percentages overall but with some differences observed in subgroups. This study suggests important gains have been made in maternal v

Abstract:
INTRODUCTION: Given the increased risk for infections among pregnant patients and newborns, vaccination against influenza (&gt;50,000,000 annual US cases affecting all ages) and pertussis (&gt;15,000 annual US cases disproportionately affecting newborns) are recommended among pregnant patients in order to protect them and their babies via passive immunity to cover a newborn’s window of vaccine ineligibility. Though flu and Tdap vaccination rates among pregnant patients have been trending upwards nationally, there is still room for improvement to achieve optimal rates. OBJECTIVES: The primary o

Abstract:
Various unicellular algae produce omega-3 (w3) very-long-chain polyunsaturated fatty acids (VLC-PUFA), which are rarely found in higher plants. In this research and other studies from our laboratories, it has been demonstrated that the marine unicellular alga Nannochloropsis (Eustigmatophyceae) can be used as a reliable and high quality source for the w3 VLC-PUFA eicosapentaenoic acid (EPA). This alga is widely used in mariculture systems as the primary component of the artificial food chain in fish larvae production, mainly due to its high EPA content. Furthermore, w3 fatty acids are essentia

Abstract:
This report describes an updated methodology to estimate overall and unintended pregnancy rates for the United States from 2010–2019, and examines differences by demographic factors. Machine learning models were used to impute missing information on induced abortions, and data integration methods were used to combine estimates of abortions, live births, and pregnancy losses to produce estimates of the total numbers of pregnancies occurring from 2010–2019 and corresponding pregnancy rates, along with outcomes related to unintended pregnancy.

Abstract:
The overall objective of the current proposal is to develop procedures to improve the pregnancy rate achieved following transfer of fresh or cryopreserved embryos produced in the laboratory into heat-stress recipients. The overall hypothesis is that pregnancy rate in heat-stressed lactating cows can be improved by use of embryo transfer and that additional gains in pregnancy rate can be achieved through development of procedures to cryopreserve embryos, select embryos most likely to establish and maintain pregnancy after transfer, and to enhance embryo competence for post-transfer survival thr

Review question / Objective: The objective of this study was to investigate the natural pregnancy outcomes(IUP,REP) of ectopic pregnancy patients by comparing MTX versus surgery, MTX versus salpingostomy, MTX versus salpingectomy, salpingostomy versus salpingectomy, MTX versus expectant treatment. Condition being studied: Ectopic pregnancy(EP) remains one of the most common gynecological emergencies and a leading cause of maternal death in early pregnancy, Increase infertility and repeat ectopic pregnancy. Surgical treatment is considered the gold standard treatment, but with advances in early
