The diagnosis of chronic endometritis in infertile asymptomatic women: a comparative study of histology, microbial cultures, hysteroscopy, and molecu…
2017
Background Chronic endometritis is a persistent inflammation of the endometrial mucosa caused by bacterial pathogens such as Enterobacteriaceae, Enterococcus, Streptococcus, Staphylococcus, Mycoplasma, and Ureaplasma. Although chronic endometritis can be asymptomatic, it is found in up to 40% of infertile patients and is responsible for repeated implantation failure and recurrent miscarriage. Diagnosis of chronic endometritis is based on hysteroscopy of the uterine cavity, endometrial biopsy with plasma cells being identified histologically, while specific treatment is determined based on microbial culture. However, not all microorganisms implicated are easily or readily culturable needing …
Análisis de resultados del Programa de Control de Calidad Externo SEIMC. Año 2018
2020
This article provides an analysis of the results obtained in 2018 by the participants inscribed in the External Quality Control Programme of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), which includes controls for bacteriology, serology, mycology, parasitology, mycobacteria, virology, molecular microbiology, and genotypic bacterial resistance. The results obtained in 2018 confirm the excellent skill and good technical standards found in the vast majority of Spanish clinical microbiology laboratories, as shown in previous editions. However, the programme again shows that erroneous results can be obtained in any laboratory and even in clinically relevant deter…
The sphingosine kinase 1 activator, K6PC-5, attenuates Ebola virus infection
2021
Summary Ebola virus (EBOV) is responsible for outbreaks with case fatality rates of up to 90% and for an epidemic in West Africa with more than ten thousand deaths. EBOV glycoprotein (EBOV-GP) is the only viral surface protein and is responsible for viral entry into cells. Here, by employing pseudotyped EBOV-GP viral particles, we uncover a critical role for sphingolipids in inhibiting viral entry. Sphingosine kinase 1 (SphK1) catalyzes the phosphorylation of sphingosine to sphingosine 1-phosphate (S1P). The administration of the SphK1 activator, K6PC-5, or S1P, or the overexpression of SphK1 consistently exhibited striking inhibitory effects in EBOV-GP-driven entry in diverse cell lines. F…
