Associations between Non-Essential Trace Elements in Women’s Biofluids and IVF Outcomes in Euploid Single-Embryo Transfer Cycles

Roberto González-Martín, Andrea Palomar, Silvia Pérez-Debén, Stefania Salsano et autres

Previous studies have found inconsistent associations between heavy metals and metalloids (cadmium, lead, mercury, and arsenic), and reproductive outcomes. The biofluid concentrations of ten non-essential trace elements (Hg, Pb, As, Ba, Sr, Rb, Cs, Sn, Ni, and Co) were evaluated in 51 …

Carbon-based thin films as a suitable alternative to metallized films for the preparation of radioactive sources

Rodolfo Fernández-Martínez, Ma Isabel Rodríguez-Tapiador, Miguel Roteta, María Pérez‐Cadenas et autres

A new method for radionuclide labeling by the use of graphene thin films was previously presented. In this work, a comparison among low energy radioactive sources supported on carbonaceous thin films on polyvinyl chloride-polyvinyl acetate copolymer (VYNS), based on the use of …

Higher Concentrations of Essential Trace Elements in Women Undergoing IVF May Be Associated with Poor Reproductive Outcomes Following Single Euploid Embryo Transfer

Roberto González-Martín, Andrea Palomar, Silvia Pérez-Debén, Stefania Salsano et autres

Essential trace elements are micronutrients whose deficiency has been associated with altered fertility and/or adverse pregnancy outcomes, while surplus may be toxic. The concentrations of eight essential trace elements were measured using inductively coupled mass spectrometry (ICP-MS) and assessed with respect to …

Assessment of the ecological risk and mobility of arsenic and heavy metals in soils and mine tailings from the Carmina mine site (Asturias, NW Spain)

Rodolfo Fernández-Martínez, Noelia Corrochano, Jéssica Álvarez-Quintana, Almudena Ordóñez et autres

An evaluation of the pollution, distribution, and mobility of arsenic and heavy metals in spoil heaps and soils surrounding the abandoned Carmina lead-zinc mine (Asturias, northern Spain) was carried out. Fractionation of arsenic was performed by an arsenic-specific sequential extraction method; while, …

Bioaccumulation of Non-Essential Trace Elements Detected in Women’s Follicular Fluid, Urine, and Plasma Is Associated with Poor Reproductive Outcomes following Single Euploid Embryo Transfer: A Pilot Study

Andrea Palomar, Roberto González-Martín, Alicia Quiñonero, Nuria Pellicer et autres

This study aims to determine the association of non-essential trace elements present in follicular fluid, plasma, and urine with reproductive outcomes of women undergoing intracytoplasmic sperm injection (ICSI), preimplantation genetic testing for aneuploidies (PGT-A) and single frozen euploid embryo transfer (SET/FET). This …
