Currently, most clinical studies in metabolomics only consider a single type of sample such as urine, plasma, or feces and use analytical platform, either NMR MS. Although some have already investigated data from multiple fluids, the information is limited to unique platform. On other hand, investigating human metabolome that combine multi-analytical platforms focused on biofluid. Combining types for one patient using multimodal approach (NMR MS) should extend coverage. Pre-analytical phases...
Oviductal extracellular vesicles (oEVs) have been proposed as key modulators of gamete/embryo maternal interactions. The aim this study was to examine the metabolite content oEVs and its regulation across estrous cycle in cattle. EVs were isolated from bovine oviducts ipsilateral contralateral ovulation at four stages (post-ovulatory stage, early late luteal phases, pre-ovulatory stage). metabolomic profiling performed by proton nuclear magnetic resonance spectroscopy (NMR). NMR identified...
In the present study we tested whether regulation of metabolome in bovine oviductal fluid depended on stage oestrous cycle, side relative to ovulation and local concentrations steroid hormones. Luminal samples from both oviducts were collected preovulatory, postovulatory, mid- late luteal phases, cyclic cows at a abattoir (18–27 per side). The metabolomes assessed by proton nuclear magnetic resonance spectroscopy (H-NMR). all, 39 metabolites identified, among which amino acid glycine energy...
We investigated the effect of maternal sire on early pregnancy failure (between D0, day insemination and D90) in their progeny during first second lactations (n=3508) Holstein breed. The estimated breeding value (EBV) for cow fertility 12 bulls (reliability⩾0.95) was used to create following three groups: low, medium high EBV (EBV from -0.7 1 expressed as genetic standard deviation relative mean breed). In daughters (93 516 per bull), progesterone measurement carried out artificial (AI; D0)...
Metabolomics may identify biomarkers in blood that differentiate pregnant from open embryo recipients. Fresh and vitrified/warmed, vitro-produced embryos were transferred to Holstein recipients (discovery group). Recipient plasma collected on Day-0 (estrus) Day-7 (before transfer) analyzed by nuclear magnetic resonance (N = 36 metabolites quantified). Metabolites whose concentrations differed between [(P < 0.05); false discovery rate (FDR) (P 0.05)]. Biomarkers identified (receiver operator...
Contents Oestrous detection is crucial for successful dairy cow reproduction. Bulls identify cows in oestrus by oestrous‐specific odours especially urine and vaginal fluid. These have been used to train dogs detect heat. To improve simplify the dog training, a spray containing synthetic oestrous molecules was developed. The objective of this study test on similarities natural substance thus assess its suitability as training heat dogs. Ten privately owned various breeds were trained. Dogs...
Selection of competent recipients before embryo transfer (ET) is indispensable for improving pregnancy and birth rates in cattle. However, prediction can fail when the competence ignored. We hypothesized that potential biomarkers could improve with information on embryonic competence. In vitro-produced embryos cultured singly 24 h (from d 6 to 7) were transferred 7 synchronized as fresh or after freezing thawing. Recipient blood was collected 0 (estrus; n = 108) (4-6 ET; 107) plasma analyzed...
Abstract The maternal metabolic environment can be detrimental to the health of offspring. In a previous work, we showed that high-fat (HH) feeding in rabbit induced sex-dependent adaptation fetus and led syndrome adult As early development representing critical window susceptibility, present work aimed explore effects HH diet on oocyte, preimplantation embryo its microenvironment. oocytes from females diet, transcriptomic analysis revealed weak modification content transcripts mainly...
In cattle, lateral asymmetry affects ovarian function and embryonic sex, but the underlying molecular mechanisms remain unknown. The plasma metabolome of recipients serves to predict pregnancy after embryo transfer (ET). Thus, aim this study was investigate whether exhibits distinct patterns according sex fetus carried by recipient active ovary side (AOS), i.e., right (RO) or left (LO). We analyzed synchronized 1H+NMR on day 0 (estrus, n = 366) 7 (hours prior ET; 367). Thereafter, a subset...
Abstract The success of embryo development and implantation depends in part on the environment which evolves. However, composition uterine fluid surrounding peri-implantation period remains poorly studied. In this work, we aimed to develop a new strategy visualize, collect, analyze both blastocoelic liquid juxta-embryonic from vivo rabbit embryos. Using high-resolution ultrasound biomicroscopy, embryos were observed as fluid-filled anechoic vesicles, some surrounded by thin layer fluid....
Metabolomics has been increasingly used in animal and food sciences. Animal health is one of the most important factor that can also alter integrity welfare. Some studies have already investigated link between metabolic profile dairy animals. These metabolomics often consider a single type sample using analytical platform (nuclear magnetic resonance or mass spectrometry). Only few with multi-platform approaches are multi sample, but they mainly cows' metabolome although goats present similar...
