Coronary artery dissection. Follow-up by MDCT.
2009
and a feature consistent with a thrombus, probably located in the false lumen (Figure, D). Based on these findings, a new coronary angiography with possible surgical revascularization was planned, but 12 hours after the MDCT examination, the patient experienced an episode of chest pain with ST-segment elevation from V1 to V5, complicated by electromechanical dissociation, and culminating in death. A post-mortem study was not performed. This case illustrates the usefulness of MDCT for follow-up of coronary stents located in proximal segments, and for identifying specific complications: extension of a dissection and even visualization of a coronary thrombus.
Long-term outcome of patients with NSTEMI and nonobstructive coronary arteries by different angiographic subtypes
2021
Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes.We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortal…
Arte digitalizado y arte digital: las manifestaciones artísticas en la era digital
2003
Analizamos las potencialidades que el medio digital ofrece al campo de la creación, constatando la aparición de nuevas obras más interactivas, abiertas y dinámicas y de un nuevo tipo de espectador más activo. Destacamos las repercusiones que este medio está ejerciendo en el mundo de los museos y las galerías que están apostando, en algunos casos, por incorporar estas obras a sus espacios expositivos y al mercado del arte. Reseñamos la importancia de Internet y el surgimiento del net-art, así como de la Realidad Virtual y el Arte evolutivo. (A)

Presentation of an Immunodominant Immediate-Early CD8+ T Cell Epitope Resists Human Cytomegalovirus Immunoevasion.
2013
Control of human cytomegalovirus (HCMV) depends on CD8+ T cell responses that are shaped by an individual's repertoire of MHC molecules. MHC class I presentation is modulated by a set of HCMV-encoded proteins. Here we show that HCMV immunoevasins differentially impair T cell recognition of epitopes from the same viral antigen, immediate-early 1 (IE-1), that are presented by different MHC class I allotypes. In the presence of immunoevasins, HLA-A- and HLA-B-restricted T cell clones were ineffective, but HLA-C*0702-restricted T cell clones recognized and killed infected cells. Resistance of HLA-C*0702 to viral immunoevasins US2 and US11 was mediated by the alpha3 domain and C-terminal region …
Chemotherapy Sensitizes Colon Cancer Initiating Cells to Vγ9Vδ2 T Cell-Mediated Cytotoxicity
2013
Colon cancer comprises a small population of cancer initiating stem cells (CIC) that is responsible for tumor maintenance and resistance to anti-cancer therapies, possibly allowing for tumor recapitulation once treatment stops. Combinations of immune-based therapies with chemotherapy and other anti-tumor agents may be of significant clinical benefit in the treatment of colon cancer. However, cellular immune-based therapies have not been experimented yet in the population of colon CICs. Here, we demonstrate that treatment with low concentrations of commonly used chemotherapeutic agents, 5- fluorouracyl and doxorubicin, sensitize colon CICs to Vc9Vd2 T cell cytotoxicity. Vc9Vd2 T cell cytotox…
