The increased cardiovascular risk present in chronic kidney disease (CKD) is related to the development of endothelial dysfunction, whose mechanisms are still unclear. Accumulation toxins and proinflammatory cytokines may constitute danger-associated molecular patterns (DAMP) which cells continuously exposed. Potential involvement recognizing DAMP, such as TLR inflammasomes, has been explored.Endothelial culture were exposed sera samples collected from patients with CKD: (i) stages 4-5 not...
Trophoblast invasion is a temporally and locally restricted process, which regulates implantation oxygen arrival to the embryo through dialog with spiral artery endothelium. factors angiogenic potential are activated by hypoxia. Their capacities induce proliferation, migration, of trophoblastic cells have been investigated.The expression interleukin (IL)-6, CD126, CD130, vascular endothelial growth factor (VEGF), hypoxia inducible factor-1alpha (HIF-1alpha) has silenced in JEG-3...

Abstract Problem The aim of this study was to investigate the possible relationship between vaginal/rectal microbiome disbalances and miRNA expression with infertility. Method Observational, exploratory, preliminary study. A total 287 multiple IVF failure infertile patients were recruited. Twenty fertile women, not failure, recruited as control group. Swab samples collected from vagina rectum. Microbial composition by NGS real‐time PCR vaginal rectal measured. Immunometabolic markers blood...
In this study, we have evaluated the relationship between acrosome reaction-inducing activity of individual human follicular fluid samples and their steroid content. Eighteen were obtained during egg retrieval in six patients undergoing assisted fertilization. Motile spermatozoa incubated modified Tyrode's medium (26 mg/ml bovine serum albumin) for 20 h at 1 x 107 cells/ml. a single experiment, aliquots semen specimen simultaneously treated with an aliquot each sample. The percentage reacted...

Integrin mechanosensing plays an instrumental role in cell behavior, phenotype, and fate by transmitting mechanical signals that trigger downstream molecular cellular changes. For instance, force transfer along key amino acid residues can mediate adhesion. Disrupting binding sites within α5β1 integrin’s partner, fibronectin (FN) diminishes adhesive strength. While past studies have shown the importance of these adhesion, relationship between dynamics how integrin distributes across surface...
Problem Regulatory factors seem to be essential achieve transition from implantation window placental vascularization. A novel function of interleukin (IL)‐6 in the promotion Th2 differentiation and inhibition Th1 polarization has been demonstrated. Considering that response promotes antibody synthesis, we postulate IL‐6 could modulating quality this during pregnancy by increasing proportion blocking asymmetric antibodies. Method study We investigated expression blocking‐asymmetric‐IgG CBA/J...
Problem: CBA/J × DBA/2 abortion rate could be the consequence of a deficient local production T helper (Th2) cytokines, which cause fetal wastage via fgl2 prothrombinase. Heparin reduces significantly in mice and recurrent spontaneous (RSA) patients. We proposed to determine effect enoxaparin on levels interleukin (IL)‐6 during murine pregnancy. Method study: Recombinant human IL‐6 (rhIL‐6) or were inoculated pregnant days 6.5–12.5. sera as well culture supernatants day 9.5 fetoplacental...
The Spanish haematology external quality assessment scheme (EQAS), established in 1984, is run by the Haematology and Haemotherapy Association (AEHH) [Quality Assurance Health Care 3 (1991) 75] functions to evaluate reproducibility of diagnostic samples clinical laboratories.

Problem Several studies indicate that RANTES (regulated on activation, normal T cell expressed and secreted) is able to downregulate T‐cell responses which suggest it might be relevant for fetal tolerance induction. However, the role of in pregnancy had not been established. Here we investigate regulation during early potential failures leading losses pregnancies. Method study progesterone levels were determined sera feto‐placental units from high resorption rate CBA/J × DBA/2 pregnant...

Considering the potential adverse effects of anticoagulation in abortion treatment, we investigate whether antioxidants might exert same immunoprotection. Although fertility properties Vitamin E have been associated with its antioxidant capacity, effect on cytokine balance during pregnancy is still unknown.Pregnant females from CBA/J × DBA/2 model were orally supplemented or inoculated intraperitoneally enoxaparin. Foeto-placental units scored at 14.5 days pregnancy, and rate was calculated....
Blood smear analysis is a well-known technique in medical laboratories. The clinical relevance of this and its interpretation are very important. Consequently, monitoring laboratory performance by an external quality assessment scheme strongly recommended. This article represents practical guidance document for External Quality Assessment Scheme (EQAS) organizers setting up blood schemes. In the first part guidelines, Hematology Working Group European Committee Assurance Programmes...
Abstract Introduction The Spanish Haematology and Haemotherapy Society organizes peripheral blood smear review scheme , focused on the evaluation of diagnostic proficiency participants by cell morphology analysis. objective was to evaluate efficacy this as an educational tool improve participants.
