New Tools for Embryo Selection: Comprehensive Chromosome Screening by Array Comparative Genomic Hybridization
2014
The objective of this study was to evaluate the usefulness of comprehensive chromosome screening (CCS) using array comparative genomic hybridization (aCGH). The study included 1420 CCS cycles for recurrent miscarriage (n=203); repetitive implantation failure (n=188); severe male factor (n=116); previous trisomic pregnancy (n=33); and advanced maternal age (n=880). CCS was performed in cycles with fresh oocytes and embryos (n=774); mixed cycles with fresh and vitrified oocytes (n=320); mixed cycles with fresh and vitrified day-2 embryos (n=235); and mixed cycles with fresh and vitrified day-3 embryos (n=91). Day-3 embryo biopsy was performed and analyzed by aCGH followed by day-5 embryo tran…
The role of thrombophilia and thyroid autoimmunity in unexplained infertility, implantation failure and recurrent spontaneous abortion.
2007
The role of thrombophilia and thyroid autoimmunity in unexplained infertility (UI), implantation failure (IF) and recurrent spontaneous abortion (RSA) is controversial and poorly understood.From March, 2004 to January, 2007, 119 women were prospectively included: 32 oocyte donors, 31 patients with UI, 26 with IF and 30 with RSA. The IF and RSA groups presented normal preimplantation genetic screening. Protein C, protein S, antithrombin III, lupus anticoagulant, activated protein C resistance (APCR), immunoglobulin M and G anticardiolipin antibodies, homocystine, Factor V Leiden, prothrombin G20210A mutation, methylentetrahydrofolate reductase C677T mutation, thyroid-stimulating hormone (TSH…
Randomized study of subcutaneous low molecular weight heparin plus aspirin versus intravenous immunoglobulin in the treatment of recurrent fetal loss…
2003
Objective To compare the 2 most efficacious therapeutic regimens, intravenous immunoglobulin (IVIG) and anticoagulation with low molecular weight (LMW) heparin plus low-dose aspirin, in women with recurrent pregnancy loss associated with antiphospholipid antibodies (aPL). Methods We examined 40 women with recurrent abortion (at least 3 occurrences) and repeatedly positive test results for anticardiolipin or lupus anticoagulant. The subjects were randomly assigned to treatment with IVIG or LMW heparin plus low-dose aspirin. Both therapies were started when the women were pregnant as documented by a positive urine test. IVIG was stopped at the thirty-first week of gestation, aspirin at the th…
Antiphospholipid syndrome in obstetrics.
2003
Antiphospholipid syndrome (APLS) in pregnancy is characterized by the presence of autoantibodies in association with recurrent fetal loss and severe complications such as preeclampsia, fetal growth retardation, or placental insufficiency. The most clinically important serologic markers are lupus anticoagulant, anticardiolipin antibodies, and recently anti-beta-2-glycoprotein 1 antibodies. At present, standardization does not exist and a definitive association between specific clinical manifestation and antibody level is not yet known. Experimental data gave evidence that passive transfer of antiphospholipid antibodies result in clinical manifestation of APLS, that is, fetal loss and thromb…
Understanding of Mendelian Inheritance Model after conventional teaching methods in Secondary Education students
2015
Mostrar que una nueva propuesta de enseñanza produce mejores actitudes y aprendizajes en los alumnos requiere disponer de un análisis de lo que se hace y se consigue con la enseñanza habitual. Para realizar dicho análisis se ha efectuado un estudio histórico y epistemológico de la evolución de las ideas en genética clásica, identificando los problemas que están en su origen, las ideas que permitieron avanzar y los obstáculos que hubo que superar. Como resultado de dicho estudio se han seleccionado un conjunto de indicadores de aprendizaje que deberían manifestarse en aquellas personas que hubieran comprendido los aspectos esenciales del modelo de herencia mendeliana, que se imparte en 4º de…
Who turns to entrepreneurship later in life? - Push and pull in Finnish rural and urban areas
2014
Age is an important factor in entrepreneurship. The paths into entrepreneurship at a later age may be varied. Self-employment in later life may be either a form of partial retirement or a career option. Older individuals may also be pushed into self-employment. The focus of this paper is on the career choices of older individuals and their background motivations in Finland. The purpose is to analyse the factors and motives in terms of the push and pull dichotomy that lead individuals to enter self-employment at older ages in different types of labour markets in Finland, viz., rural and urban areas. Although some studies have focused on transitions to self-employment among older workers, que…
Y salieron ilesos del fuego: Dn 3 en la obra de Romano Melodo
2020
El uso de relatos bíblicos constituye un recurso habitual dentro de la técnica compositiva del himnógrafo bizantino Romano Melodo. Por ello, en este artículo se pretende analizar la acomodación de un episodio concreto del Antiguo Testamento (Dn 3) a lo largo del corpus atribuido Romano y se cotejan los diferentes textos que pudieron ser tenidos en cuenta como fuentes.
Diferencias en la eficacia del tratamiento y en la calidad de vida de pacientes con acné moderado y severo comparando distintas dosis de isotretinoína
2021
El acné es una enfermedad inflamatoria multifactorial de la unidad pilosebácea, con un impacto importante en la calidad de vida de las personas que lo padecen. Entre las distintas opciones terapéuticas disponibles para el manejo de las formas moderadas y severas de acné, la más resolutiva es la isotretinoína oral. Habitualmente se manejan dosis de isotretinoína superiores a 0,5 mg/kg/día, pero en los últimos años se están valorando nuevos esquemas terapéuticos utilizando como alternativa las dosis bajas de isotretinoína, para reducir el riesgo de los efectos secundarios asociados a los retinoides orales. Objetivos: El objetivo de este estudio es evaluar si existen diferencias en relación a …

IVIG in APS pregnancy
2004
For more than two decades, the intravenous administration of high doses of IgG pooled from the plasma of healthy donors (immune globulin therapy, also known as ‘IVIG’) has benefited patients with a variety of autoimmune disorders. A potential therapeutic role of IVIG in the prevention of thrombosis and of miscarriages in antiphospholipid syndrome (APS) has been postulated. Multicenter randomized controlled trials attempted to define the role of IVIG in preventing pregnancy complications in APS indicate that simple anticoagulation could not be completely satisfactory, and certain patient subgroups might take advantage of IVIG therapy alone or in combination with heparin.
