Extracellular matrix (ECM) changes after myocardial infarction (MI) need precise regulation, and next-generation sequencing technologies provide omics data that can be used in this context. We performed a meta-analysis using RNA-sequencing transcriptomic datasets to identify genes involved in post-MI ECM turnover. Eight studies available in Gene Ex...
Macronutrients represent risk factors for hyperlipidemia or diabetes. Lipid alterations and type 2 diabetes mellitus are global health problems. Overexpression of sterol regulatory element-binding factor (Srebf2) in transgenic animals is linked to elevated cholesterol levels and diabetes development. We investigated the impact of increased Srebf2 l...
Resumen
El uraco es un grueso cordón fibroso que aparece a partir del quinto mes de gestación como consecuencia de la obliteración de la alantoides. Los quistes de origen uracal se producen como consecuencia de un defecto en la obliteración de dicho conducto, anomalía que se detecta principalmente en niños y raramente en adultos. Presentamos 3 caso...
The microvascular architecture of the spleen plays an important role in the immunological function of this organ. The different types of vessels are related to different reticular cells each with their own immunomodulatory functions.
The present study describes an immunohistochemical and morphometric analysis of the various types of vessels in 21 h...
Pancreatic specimens have always been a great challenge for surgical pathologists due to their anatomic complexity and the difficulty of becoming familiar with these specimens. However, pancreatic specimens are becoming more and more common in many hospitals because of the improvements in surgical techniques and perioperative care that have dramati...
Pancreatic cancer is a dismal disease with an increasing incidence. Despite the majority of patients are not candidates for curative surgery, a subgroup of patients classified as borderline resectable pancreatic cancer can be selected in whom a sequential strategy of neoadjuvant therapy followed by surgery can provide better outcomes. Multidiscipli...
Background
Pancreatic ductal adenocarcinoma (PDAC) is one of the most devastating malignancies in developed countries because of its very poor prognosis and high mortality rates. By the time PDAC is usually diagnosed only 20-25% of patients are candidates for surgery, and the rate of survival for this cancer is low even when a patient with PDAC doe...
Nonspecific interstitial pneumonia (NSIP) is a clinical - pathological entity difficult to diagnose where actually multidisciplinary collaboration seems needed. In clinical practice we handled this patients with a considerable uncertainty because in a percentage of them we can’t get a lung biopsy. In this study, we hypothesized that asymptomatic pa...
Measurement of collagen bundle orientation in histopathological samples is a widely used and useful technique in many research and clinical scenarios. Fourier analysis is the preferred method for performing this measurement, but the most appropriate staining and microscopy technique remains unclear. Some authors advocate the use of Haematoxylin-Eos...
Pancreatic cancer, with a 5% 5-year survival rate, is the fourth leading cause of cancer death in Western countries. Unfortunately, only 20% of all patients benefit from surgical treatment. The need to prolong survival has prompted pathologists to develop improved protocols to evaluate pancreatic specimens and their surgical margins. Hopefully, the...
We aimed to explore the expression pattern of p16(INK4alpha)/Ki-67 immunocytochemical dual-staining and to establish the potential clinical utility for early detection of cervical lesions. Liquid-based cytologies of cervical specimens of cervical cancer screening were processed for p16(INK4alpha)/Ki-67 immunocytochemical dual-staining using the CIN...
Combined hepatocellular-cholangiocarcinoma is a rare primary hepatic tumour, characterized by unmistakable, intimately mixed elements of both hepatocellular carcinoma and cholangiocarcinoma. We report 2 cases in which the preoperative diagnosis was cholangiocarcinoma (case 1) and hepatocellular carcinoma (case 2). However, the microscopy of the sur...
We present four cases of pulmonary actinomycosis in patients over 40 years of age, two of them with chronic obstructive pulmonary disease (COPD), showing an increase in productive cough, episodes of dyspnea, hemoptysis and long-term fever. Routine chest radiographs revealed segmental air-space consolidation, suggestive of unresolved pneumonia or ne...
Palabras clave: pulmón, actinomicosis pulmonar, punción-aspiración con aguja fina (PAAF). Resumen. Se presentan 4 casos de actinomicosis pulmonar en pacientes mayores de 55 años, 2 de ellos con enfermedad pulmonar obstructiva crónica (EPOC), que mostraron un aumento de la tos productiva, episodios de disnea, hemoptisis y fiebre de larga evolución....
Foregut cystic malformations are common lesions in the mediastinum but are rarely found in subdiaphragmatic locations. Only a few cases have been described within the pancreas where they can easily be misdiagnosed as cystic neoplasms.
We herein present the case of a 37-year-old female with acute cholangitis in whom a diagnostic work-up revealed a 1...
Palabras clave: citología líquida, HPV, p16INK4a, anormalidades celulares, pato-logía cervical. Resumen. La citología del cuello uterino en base líquida mejora la cali-dad de la muestra y el material residual podría ser utilizado para realizar pruebas complementarias, como la detección del virus papiloma humano (HPV) y estudio inmunocitoquímico de...
The liquid-based cervical cytology improves the quality of the sample and the residual sample could be used efficiently to carry out complementary tests, such as the detection of HPV DNA and the immunocytochemical biomarkers study. The purpose of this study was to correlate the presence of HPV and immunoexpression of p16INK4a in liquid-based cervic...
Cancer of the pancreas is the fourth cause of death due to cancer in developed countries and surgeons and oncologists are showing an increasing interest in the improvement of survival. This has prompted pathologists to develop better, standardized protocols for the evaluation of surgical specimens from pancreatectomies.The different problems that t...
Se estudiaron 998 autopsias realizadas en el Servicio de Anatomía Patológica del Hospital Clínico Universitario de Valencia entre 1985 y 1992, introducidas y procesadas en el Sistema Automatizado de Registro y Control de Anatomía Patológica (SARCAP) en el Hospital «Hermanos Ameijeiras» de La Habana, Cuba. Los principales resultados fueron: predomin...
El tumor de Brenner es un tumor raro que representa aproximadamente el 1,5% de los tumores de ovario. Se define como un tumor de células transicionales compuesto por células uroteliales dispuestas en agregados sólidos o quísticos embebidos en un estroma fibroso. Se clasifica en tumor de Brenner benigno (95%), borderline (3-4%) y maligno (1%). Prese...
Brenner's tumor is a rare tumor that represents approximately 1.5% of the tumors of ovary. It is defined as a tumor of transitional cells composed by cells uroteliales arranged in solid or cystic acccumulations absorbed in a fibrous estroma. It qualifies in tumor of benign Brenner (95%), borderline (3-4%) and malignantly (1%). We present the clinic...
CD4+/CD56+ hematodermic neoplasm, formerly known as blastic NK cell lymphoma, is an aggressive and rare preculsor hematologic neoplasm recently recognized by the WHO-EORTC classification consensus for cutaneous lymphomas. The neoplasm tends to affect elderly patients, who usually present with skin lesions but often have a disseminated disease, incl...
We have performed immunocytochemical, immunoelectron microscopy, Western blot, and culture techniques using monoclonal antibodies against cytokeratin, vimentin, and desmin on 17 benign and 20 malignant effusions of pleural and ascitic origin. Triple coexpression of these three antigens was observed in benign reactive mesothelial cells as well as in...
A number of recent studies have suggested a relationship between Ewing's sarcoma (ES) and other small round cell tumours of childhood such as peripheral neuroepithelioma (PN). We report scanning electron microscopic studies on the character of induced neural differentiation in ES, neuroblastoma, PN, osteosarcoma and colon carcinoma. We found eviden...

Primary liver carcinoma (PLC) may express a certain number of markers. Here we communicate results of an analysis of five such markers (alpha-1-antitrypsin--AAT--, carcino-embryonic antigen --CEA--, alpha-fetoprotein --AFP--, and superficial --HBsAg-- and core --HBcAg-- antigens of hepatitis B virus) by means of PAP techniques in 130 cases of PLC,...
