The morphological features of a retroperitoneal teratoma in a 10-month-old girl are reported. Unlike the usual pattern of the teratoma, this tumor was composed predominantly of nephroblastomatous tissue. Histologically, glomeruloid and tubular structures were identified in nests of undifferentiated blastemal elements. Hyaline cartilage, adipose tissue, glial tissue and glands lined by mucin-sec...

Pulmonary edema is a common problem in dogs and cats in both the emergency room and the intensive care unit. A good understanding of the physiology of fluid flow through the lungs is of paramount importance for developing techniques for rational patient management. The normal lung consists of a network of capillaries lined with endothelial cells, surrounding airspaces lined with alveolar epithe...

The present lesion was the first reported case of a benign intracystic phyllodes tumor in the inguinal region. We report the case of a 51-year-old female patient who presented with an inguinal mass. A clinical diagnosis of malignant lymphoma was considered in this case. The resected tumor was well-circumscribed and showed numerous papillary nodular protrusions into a central cystic cavity (3.5×...

Stomach is considered the “gold standard” as an esophageal substitute after esophagectomy. Reflux disease is considered an unavoidable consequence of esophageal resection followed gastric interposition. Reflux esophagitis shows a progression from inflammation to erosions and to the development of columnar lined metaplasia. With the use of a gastric interposition, the most popular option to reco...

The study of detached eclipsing binaries is one of the most powerful ways to investigate the properties of individual stars and stellar systems. We present preliminary masses, radii and effective temperatures for the eclipsing binary WWAurigae, which is composed of two metallic-lined A-type stars. We also reanalyse the data on HD23642, an A-type eclipsing binary member of the Pleiades open clus...

High-precision radial-velocity techniques, which enabled the detection of extrasolar planets are now sensitive to relativistic effects in the data of spectroscopic binary stars (SBs). We show how these effects can be used to derive the absolute masses of the components of eclipsing single-lined SBs and double-lined SBs from Doppler measurements alone. High-precision stellar spectroscopy can thu...
