INTRODUCTION: Involvement of endogenous cannabinoids (eCBs) in obesity is well-characterized. However, information regarding eCB physiology in obesity associated with pregnancy is sparse. METHODS: From at least 9 months before conception, non-pregnant baboons (Papio spp.) were fed a diet of either 45% fat (HFD; n=11) or 12% fat or a control diet (CTR; n=11), and dietary intervention continued through pregnancy. Maternal and fetal venous plasma samples were evaluated using liquid chromatography-mass spectrometry to quantify anandamide (AEA) and 2-arachidonoyl glycerol (2-AG)...

BACKGROUND: Exposure to perfluoroalkyl substances (PFASs) may increase risk for metabolic diseases; however, epidemiologic evidence is lacking at the present time. Pregnancy is a period of enhanced tissue plasticity for the fetus and the mother and may be a critical window of PFAS exposure susceptibility. OBJECTIVE: We evaluated the associations between PFAS exposures and metabolic outcomes in pregnant women. METHODS: We analyzed 1,240 pregnant women from the Spanish INMA [Environment and Childhood Project (INfancia y Medio Ambiente)] birth cohort study (recruitment period: 2003-2008) with measured first pregnancy trimester plasma concentrations of four PFASs (in nanograms/milliliter)...

INTRODUCTION: Preeclampsia is characterized by reduced invasion capacity of trophoblasts involving lower matrix metalloproteinase (MMP) activity. Cell invasion is reduced by reversion-inducing-cysteine-rich protein with Kazal motifs (RECK), a plasma membrane protein that inhibits MMP in several cell types. However, it is unknown whether this mechanism happens in the human placenta from preeclampsia. The hypothesis of this study sustains that RECK expression is increased leading to reduced trophoblasts invasion in preeclampsia...

Short-chain fatty acids (SCFAs), the end products of dietary fiber, influence the immune system. Moreover, during pregnancy the maternal microbiome has a great impact on the development of the offspring's immune system. However, the exact mechanisms by which maternal SCFAs during pregnancy and lactation influence the immune system of offspring are not fully understood. We investigated the molecular mechanisms underlying regulatory T cell (Treg) differentiation in offspring regulated by a maternal high fiber diet (HFD)...

Background: The explosive spread of Zika virus (ZIKV) and associated microcephaly present an urgent need for sensitive and specific serodiagnostic tests, particularly for pregnant women in dengue virus (DENV)-endemic regions. Recent reports of enhanced ZIKV replication by dengue-immune sera have raised concerns about the role of previous DENV infection on the risk and severity of microcephaly and other ZIKV complications. Methods: Enzyme-linked immunosorbent assays (ELISAs) based on ZIKV and DENV non-structural protein 1 (NS1) were established to test acute, convalescent-phase and post-convalescent-phase serum/plasma samples from reverse-transcription polymerase-chain reaction-confirmed-cases including 20 primary ZIKV, 25 ZIKV with previous dengue, 58 secondary DENV, and 16 primary DENV1 infections...

Background: High pregnancy-associated plasma protein-A (PAPP-A) levels are linked to atherosclerosis and associate with increased mortality in prevalent dialysis patients. We investigated associations of PAPP-A, measured at dialysis initiation, with cardiovascular disease (CVD), CVD risk factors and mortality in incident dialysis patients, and explored if body composition and inflammation modulated these associations. Methods: Baseline plasma PAPP-A levels, inflammation biomarkers and body composition, using dual-energy X-ray absorptiometry, were measured in 286 incident dialysis patients...

Context: Short-term glucocorticoid exposure increases serum insulinlike growth factor I (IGF-I) concentrations but antagonizes IGF-I tissue signaling. The underlying mechanisms remain unknown. Objective: To identify at which levels glucocorticoid inhibits IGF-I signaling. Design and Methods: Nineteen healthy males received prednisolone (37.5 mg/d) and placebo for 5 days in a randomized, double-blinded, placebo-controlled crossover study. Serum was collected on days 1, 3, and 5, and abdominal skin suction blister fluid (SBF; ~interstitial fluid) was taken on day 5 (n = 9) together with muscle biopsy specimens (n = 19)...

Cystic ovarian disease (COD) is one of the main causes of infertility in dairy cattle. It has been postulated that the insulin-like growth factor (IGF) system may contribute to follicular persistence and development of COD. The initiation of the IGF response is a result of interactions between IGF-binding proteins (IGFBPs) and IGFBP proteases, mainly pregnancy-associated plasma protein A (PAPP-A). IGFBPs bind IGFs with high affinity and consequently regulate their access to IGF receptors (IGFRs). The aim of this research was to determine variations in components of the IGF system in the ovaries of cows with persistent follicles induced by long-term administration of progesterone...

Preeclampsia is a pregnancy disorder characterized by imbalance between pro- and anti-inflammatory cytokines associated with high plasma levels of uric acid and Interleukin-1 beta (IL-1β). The inflammasome is a protein complex that mediates innate immune responses via caspase-1 activation promoting secretion of IL-1β and IL-18 in their active forms, and also release of the high-mobility group box 1 protein (HMGB1). As the placenta seems to play an important role in the pathogenesis of PE, the present study investigated the expression of genes and proteins related to the inflammasome in placentas from pregnant women with severe preeclampsia...
