A case of Fitz Hugh Curtis syndrome mimicking an acute abdomen
2021
Fitz Hugh Curtis syndrome, also known as acute perihepatitis, associates pelvic inflammatory disease with the presence of Chlamydia trachomatis or Neisseria gonorrhoeae as the main causative pathogens.
 Symptomatology is a nonspecific one. Right upper quadrant pain, fever, nausea and vomiting are the most commonly encountered symptoms.
 Imaging data are also nonspecific and often show intra-abdominal changes with no particularity.
 As it is difficult to suspect Fitz Hugh Curtis syndrome upon first impression, laparoscopy and direct visualization of the peritoneum and liver adhesions are needed in the diagnostic process. The specific aspect of the fibrinous strands can raise t…
Transdiferenciación de fibroblastos a hepatocitos mediante reprogramación celular : papel de Gata4 en el bloqueo de la reprogramación de células somá…
2013
En esta tesis doctoral se muestra la conversión directa de fibroblastos embrionarios de ratón a células con morfología y fenotipo similares al hepatocito mediante la expresión retroviral de seis factores de transcripción hepáticos, Hhex, Gata4, Foxa2, HNF4α HNF1α y HNF6. Los fibroblastos infectados mantenidos durante 3-4 semanas en cultivo adquieren una morfología epitelial y expresan genes típicamente hepáticos como Albumina, Cyp7a1, Tat o Slc10a1 a niveles próximos al hepatocito. Durante la manipulación de los fibroblastos mediante la expresión de los factores de transcripción ya mencionados, observamos que el factor de transcripción Gata4 es capaz de bloquear la reprogramación a células …
A robust reprogramming strategy for generating hepatocyte-like cells usable in pharmaco-toxicological studies.
2023
Abstract Background High-throughput pharmaco-toxicological testing frequently relies on the use of established liver-derived cell lines, such as HepG2 cells. However, these cells often display limited hepatic phenotype and features of neoplastic transformation that may bias the interpretation of the results. Alternate models based on primary cultures or differentiated pluripotent stem cells are costly to handle and difficult to implement in high-throughput screening platforms. Thus, cells without malignant traits, optimal differentiation pattern, producible in large and homogeneous amounts and with patient-specific phenotypes would be desirable. Methods We have designed and implemented a no…
