OBJECTIVES To assess the practical use of SonoAVC in an IVF program, and to establish new criteria for hCG administration based on follicular volume. DESIGN Prospective clinical study. SETTING Private IVF Center. PATIENT(S) Fifty-eight women with infertility undergoing IVF. INTERVENTION(S) Two dimensional (2D) and three dimensional (3D) scanning on(More)
Ovarian aging is associated with gradual follicular loss by atresia/apoptosis. Increased production of toxic metabolites such as reactive oxygen species (ROS) and reactive nitrogen species as well as external oxidant agents plays an important role in the process of ovarian senescence and in the pathogenesis of ovarian pathologies such as endometriosis and(More)
OBJECTIVE To correlate angiotensin II (AngII) receptor expression by granulosa-lutein (GL) cells from gonadotropin-stimulated follicles with infertility diagnosis and IVF parameters. DESIGN The mRNA of angiotensin receptors type 1 (AT1) and type 2 (AT2) was studied in aspirated GL cells. SETTING University laboratory and private IVF center. PATIENT(S)(More)
The aim of this study was to investigate whether the automatic measurement of follicular volume by three-dimensional (3D) ultrasound can predict the number of mature oocytes retrieved. A prospective cohort study including 47 women undergoing in vitro fertilization was conducted in a private fertility center. Follicular growth was monitored both manually and(More)
OBJECTIVE To study the expression of mRNA for Kit ligand 1 (KL1), KL2, FSH receptor (FSHR), pregnancy-associated plasma protein (PAPP) and P450 in granulosa-lutein cells from IVF patients and its relationship with the infertility diagnosis and IVF outcome. DESIGN In vitro assays. SETTING University laboratory and private IVF center. PATIENT(S) A total(More)
OBJECTIVE To study the integrity of the FSH receptor (FSHR) signaling pathway in granulosa-lutein cells at the time of egg retrieval and its relationship with the infertility diagnosis. DESIGN In vitro assays. SETTING University laboratory and private IVF center. PATIENT(S) Patients undergoing IVF: 35 controls (no ovarian factor, NOF), 28 poor(More)
Oxidative stress (OS) plays an important role in all physiological processes. The effect of OS on cellular processes is modulated by the ability of the cell to express genes implicated in the reversal of lipid, protein, and DNA injury. Aldehyde dehydrogenase 3, member A2 (ALDH3A2) is a ubiquitous enzyme involved in lipid detoxification. The objective of(More)
The soil bacterium Bradyrhizobium (Chamaecytisus) strain BGA-1 produces an extracellular polymeric substance (EPS) that, in the presence of Fe3+, Al3+ or Th4+ solutions, forms a gel-like precipitate composed of polysaccharide, protein, lipopolysaccharide and the metal. Precipitation of the main component of the EPS, the extracellular polysaccharide, and(More)
The thorium effect on Bradyrhizobium growth was assayed in liquid media. Th4+ inhibited the growth of Bradyrhizobium (Chamaecytisus) BGA-1, but this effect decreased in the presence of suspensions of live or dead bacterial cells. Th4+ induced the formation of a gel-like precipitate when added to a dense suspension of B. (Chamaecytisus) BGA-1 cells. Viable(More)
