Ovarian steroid cell tumours (not otherwise specified) are rare neoplasms of the ovary and are classified under lipid cell tumours. Their diagnosis can be considered as one of exclusion. Histopathologically, the tumour should carefully be evaluated for microscopic features of malignancy, but it is essential for the clinician and the pathologist to remember that in these tumours, pathologically ...

This paper proposes a framework for quantifying the macroscopic impacts of delivery goods made by double-parked vehicles in urban arterial using microscopic simulation. It is applied to a real urban corridor: the Lafayette Avenue in Lyon (France). The framework combines traffic states with stochastic and microscopic freight demand generation model, i.e. the delivery movements and the delivery d...

Congenital diaphragmatic hernia is a common congenital anomaly of uncertain etiology. Its association with multiple congenital anomalies in various organs is well recognized and antenatal radiological evidence of congenital diaphragmatic hernia warrants thorough evaluation to detect other anomalies, some of which can be life threatening. Rarely, heterotopic hepatic tissue is identified in the h...

A presentation of techniques for organ culture and an evaluation of the effects of organ culture on human and animal corneas is presented. The gross and microscopic appearance of cultured corneas, phase contrast microscopic study, and histopathology of organ-cultured corneas are discussed. These obseivations show that corneas can be stored in organ culture and that after prolonged in vitro pres...

Restrictive cardiomyopathies in the pediatric population have diverse etiologies, including storage diseases like hemosiderosis, glycogenoses and desmin with its associated proteins. Desmin-related myopathy is a rare familial disorder of the cardiac and skeletal muscle characterized by intrasarcoplasmic accumulation of desmin-reactive deposits in the muscle cells. The patients commonly present ...

Accurate analysis of cerebrospinal fluid (CSF) provides a wide range of information about the neurological health of the patient. CSF can be withdrawn from either of two cisterns in dogs and cats using relatively safe techniques. Once CSF has been collected it must be analysed immediately and methodically. Evaluation should consist of macroscopic, quantitative and microscopic analyses. As part ...

Microscopic models of the interaction between grain boundaries (GBs) and both dislocations and cracks are of importance in understanding the role of microstructure in altering the mechanical properties of a material. A recently developed mixed atomistic and continuum method is reformulated to allow for the examination of the interactions between GBs, dislocations, and cracks. These calculations...

An indirect hemagglutination test for the diagnosis of leptospirosis is described; the test uses a soluble antigen from serotype patoc to sensitize sheep erythrocytes which are then fixed with glutaraldehyde. Evaluation of this procedure indicates that it is more reliable than the conventional macroscopic agglutination test and, in contrast with both microscopic and macroscopic agglutination te...

biliary papillomatosis is a disorder characterized by numerous adenomatous polyps of variable distribution and extent in intrahepatic bile ducts. it should be considered as a premalignant condition because a high proportion of the lesions undergo malignant transformation. in this report, we present a patient with abdominal pain and jaundice. according to his presenting signs and symptoms, ercp ...

Asymptomatic microscopic hematuria is a common finding that demands urologic evaluation. Of the 236 patients over the age of 40, 6.8% were found to have a genitourinary cancer, while 27.5% had other significant urologic disease. However, 52.1% of the patients had unknown etiology of microscopic hematuria and 13.6% had insignificant urologic lesions. Of the 72 patients under the age of 40 a posi...
