Circulating Tumor Cells (CTCs): A Unique Model of Cancer Metastases and Non-invasive Biomarkers of Therapeutic Response

2021

Late-stage cancer metastasis remains incurable in the clinic and is the major cause death in patients. Circulating tumor cells (CTCs) are thought to be metastatic precursors shed from the primary tumor or metastatic deposits and circulate in the blood. The molecular network regulating CTC survival, extravasation, and colonization in distant metastatic sites is poorly defined, largely due to challenges in isolating rare CTCs. Recent advances in CTC isolation and ex vivo culture techniques facilitates single-cell omics and the development of related animal models to study CTC-mediated metastatic progression. With these powerful tools, CTCs can potentially be used as non-invasive biomarkers pr…

2023

Diseño, implantación y evaluación de la eficiencia de un modelo de gestión por procesos de la enfermedad litiásica urinaria en una unidad de litotricia. Introducción y Objetivo La enfermedad litiásica (EL) tiene un carácter crónico definido por distintos factores de riesgo que no se han ponderado ni relacionado entre sí, para poder establecer grupos de riesgo, ni establecido su seguimiento. El presente trabajo pretendió coordinar los distintos factores demográficos, metabólicos, anatómicos, etc. que influyen en la EL creando un nuevo modelo de gestión de la misma, basado en la pirámide poblacional de Kaiser-Permanente. Con ello se generó una clasificación de estos pacientes en distintos gru…

Apoptotic-like Leishmania exploit the host´s autophagy machinery to reduce T-cell-mediated parasite elimination

2015

Apoptosis is a well-defined cellular process in which a cell dies, characterized by cell shrinkage and DNA fragmentation. In parasites like Leishmania, the process of apoptosis-like cell death has been described. Moreover upon infection, the apoptotic-like population is essential for disease development, in part by silencing host phagocytes. Nevertheless, the exact mechanism of how apoptosis in unicellular organisms may support infectivity remains unclear. Therefore we investigated the fate of apoptotic-like Leishmania parasites in human host macrophages. Our data showed--in contrast to viable parasites--that apoptotic-like parasites enter an LC3(+), autophagy-like compartment. The compartm…

When the Grafting of Double Decker Phthalocyanines on Si(100)-2 × 1 Partly Affects the Molecular Electronic Structure

2016

International audience; A combined X-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and density functional theory (DFT) study has been performed to characterize the adsorbate interaction of lutetium biphthalocyanine (LuPc2) molecules on the Si(100)-2 × 1 surface. Large molecule–substrate adsorption energies are computed and are found to compete with the molecule–molecule interactions of the double decker molecules. A particularly good matching between STM images and computed ones confirms the deformation of the molecule upon the absorption process. The comparison between DFT calculations and XP spectra reveals that the electronic distribution in the two plateaus …

How cancer cells cross lymphatic endothelium?

2014

The lymphatic microcirculation is a key component of metastatic spread providing a pathway for cancer cell dissemination, and the endothelium seems to enhance or promote the invasiveness of certain cancer cells. Furthermore, some tumors secrete lymphangiogenic growth factors acting on the lymphatic vasculature to facilitate metastasis. This study, based on 875 ultrastructural serial sections and 9 three-dimensional reconstructions of 28 initial lymphatics, clarify the transmigration mechanism of cancer cells from the extravascular matrix to the lumen of initial lymphatics. The lymphatic identification and distribution were assessed by transmission electron microscopy and immunohistochemistr…

Metastatic neuroblastoma to the mandible in a 3-year-old boy : a case report

2007

Although neuroblastoma is a relatively common malignancy of childhood and its dissemination to distant organs is often seen, metastasis to the mandible is rare. A 3-year-old boy which a mandibular soft tissue mass was the initial presenting symptom of disseminated neuroblastoma is reported. The results of biopsy were inconclusive and the differential diagnosis from the imaging studies included lymphoma, soft tissue sarcoma, and osteosarcoma. A metastatic work-up disclosed neuroblastoma of the adrenal gland origin with osseous and bone marrow metastases. Urinary catecolamines were also increased. Regarding the widespread features of the tumor and lack of adequate treatment at this stage of d…

Masa intraoral de rápido crecimiento: a propósito de un caso

2005

La aparición de una masa intraoral supone un motivo de consulta frecuente en nuestra especialidad. La mayoría de los casos corresponden a lesiones benignas y, dentro de las malignas, a tumores primarios intraorales. Las metástasis suponen menos del 1 % de las lesiones malignas. Presentamos el caso de una mujer de 86 años de edad, sin antecedentes oncológicos, que acudió a nuestro servicio presentando una masa intraoral asintomática, de crecimiento rápido y volumen considerable, sin otros hallazgos de interés a la exploración. La lesión se acompañaba de erosión ósea subyacente. El resultado de la biopsia fue de adenocarcinoma metastático de probable origen abdominal, si bien el tumor primari…

A coupled discontinuous Galerkin-Finite Volume framework for solving gas dynamics over embedded geometries

2021

Author(s): Gulizzi, Vincenzo; Almgren, Ann S; Bell, John B | Abstract: We present a computational framework for solving the equations of inviscid gas dynamics using structured grids with embedded geometries. The novelty of the proposed approach is the use of high-order discontinuous Galerkin (dG) schemes and a shock-capturing Finite Volume (FV) scheme coupled via an $hp$ adaptive mesh refinement ($hp$-AMR) strategy that offers high-order accurate resolution of the embedded geometries. The $hp$-AMR strategy is based on a multi-level block-structured domain partition in which each level is represented by block-structured Cartesian grids and the embedded geometry is represented implicitly by a…

La atención a la salud materno-infantil en el área de salud de La Ribera (Valencia) desde la perspectiva de las gestantes y las matronas: aproximacio…

2020

Justificación e introducción La atención al parto experimentó profundos cambios durante la segunda mitad del siglo XX con la introducción del parto en el ámbito hospitalario. Como reacción a ello surge el movimiento del parto normal, que pretende humanizar la asistencia al parto que se presta dentro de los hospitales. En cada hospital este proceso se ha desarrollado en diferente tiempo y forma. En el caso del Hospital Universitario de La Ribera (Alzira, Valencia), la introducción de los protocolos de atención al parto normal se produce de forma progresiva entre los años 2011 y 2014. En ese momento, surge la necesidad de explorar la acogida de estos cambios entre las gestantes del área de sa…

El derecho a morir dignamente: una oportunidad para el impulso ético del Trabajo Social

2021

La creciente importancia de las enfermedades crónicas como causa de muerte y la atención que actualmente se presta al final de la vida han creado interés en el papel de las disciplinas sociosanitarias en el momento y el modo de muerte. En la actualidad, pocos países han legalizado o despenalizado la eutanasia y el suicidio asistido. Este artículo realiza una revisión narrativa con el objetivo de conocer los aspectos éticos y jurídicos que envuelven el derecho a morir dignamente, el suicidio asistido y la eutanasia en los países donde se han regulado estas prácticas, así como su vinculación con los principios éticos inherentes al Trabajo Social. Los resultados muestran que estas prácticas de…
