VIDEOLAPAROSCOPYC OVUM PICK-UP COMPARATIVE IN DORPER AND SANTA INES EWES

Ciência Animal Brasileira, 2016
This study aimed to compare the number of aspirated follicles, recovered oocytes, oocyte quality and viability between Dorper and Santa Inês ewes submitted to the videolaparoscopic ovum pick-up.

Bovine Follicular Dynamics, Oocyte Recovery,and Development of Oocytes Microinjected with a Green Fluorescent Protein Construct [PDF]

, 1999
The present study was carried out to 1) evaluate the viability of in vitro fertilized zygotes after microinjection of DNA, 2) assess the influence of oocyte quality upon the development rate of embryos when injected with DNA, and 3) determine the ...

Parallel Analysis of Acidic and Basic Proteoforms in Cell Lysates via Native Cation and Anion Exchange Chromatography—Native Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Comprehensive characterization of proteoforms in complex biological systems remains a significant challenge. While native ion‐exchange chromatography (IEC) hyphenated with native mass spectrometry (nMS) is a powerful tool for resolving proteoforms, three critical limitations persist: restricted volatile buffers causing nonlinear pH gradients ...

Physiological and behavioral parameters of pain and stress in mares during and after transvaginal ultrasound-guided follicular aspiration

Frontiers in Veterinary Science
IntroductionThe use of transvaginal ultrasound-guided follicle aspiration (TVA) for oocyte collection has become a widely used procedure in horses for in vitro embryo production (IVEP).

Delayed intra-abdominal bleeding following trans-vaginal ultrasonography guided oocyte retrieval for in vitro fertilization in patients at risk for thrombo-embolic events under anticoagulant therapy [v1; ref status: indexed, http://f1000r.es/1uf]

F1000Research, 2013
We report herein, two cases of massive delayed (2 and 4 days) intra abdominal hemorrhage following ovum pick-up (OPU), in patients at risk for thrombo-embolic events, who concomitantly used therapeutic doses of low molecular weight heparin (LMWH).

First Birth of Cheetah Cubs from In Vitro Fertilization and Embryo Transfer

Animals, 2020
Approximately 30% of the Association of Zoos and Aquariums cheetah population (~350 total animals) is unlikely to breed naturally due to advanced age, health, or behavioral issues.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Nutrition-induced advanced puberty in dairy heifers does not affect ovarian response or oocyte in vitro competence despite reduced oocyte mitochondrial transcripts

Animal
While inducing early puberty in dairy heifers may seem a straightforward strategy to reduce rearing costs, it also raises concerns about potential adverse effects on reproductive function.

Beyond Substitution—An Antipositionalist's Guide to Subtraction—

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

Identification of potential biomarkers in donor cows for in vitro embryo production by granulosa cell transcriptomics [PDF]

, 2017
The Ovum Pick Up-In vitro Production (OPU-IVP) of embryos is an advanced reproductive technology used in cattle production but the complex biological mechanisms behind IVP outcomes are not fully understood.
