PURPOSE To describe ocular manifestations in patients with microscopic polyangiitis. METHODS Two patients with microscopic polyangiitis complained of ocular symptoms and underwent ophthalmologic examinations. RESULTS An 83-year-old woman (Case 1) was diagnosed with microscopic polyangiitis, according to the general clinical findings and the presence of perinuclear pattern of antineutrophil ...

Growth patterns generated by filamentous organisms (e.g. actinomycetes and fungi) involve spatial and temporal dynamics at different length scales. Several mathematical models have been proposed in the last thirty years to address these specific dynamics. Phenomenological macroscopic models are able to reproduce the temporal dynamics of colony-related quantities (e.g. colony growth rate) but do...

-Evidence is presented that microscopic tumours (of a transplantable murine mammary carcinoma, M8013X) grow faster than larger, palpable, tumours. Microscopic tumours are also more radiosensitive than larger tumours. The decrease in radiosensitivity in larger tumours is prevented to a large extent by misonidazole, which has no significant effect on the radiosensitivity of microscopic tumours. T...

Growth and pattern formation occur simultaneously in many epimorphic fields and it has been suggested that specification of positional information is somehow linked to cell division. It is possible, therefore, that boundary regions responsible for the specification of positional information produce cell growth factors. In this paper I review the properties of some known growth factors, describe...

Hercep Test (DAKO) is an immunohistological screening kit to select cases of advanced breast cancer with indication for treatment with a humanized mouse monoclonal antibody to human epidermal growth factor receptor-2, trasthzumab (Herceptin). We report a case of an 84-year-old female with invasive ductal carcinoma of the right breast, whose neoplastic cells showed a unique staining pattern in H...

Texture classification can be concluded as the problem of classifying images according to textural cues, that is, categorizing a texture image obtained under certain illumination and viewpoint condition as belonging to one of the pre-learned texture classes. Therefore, it would mainly pass through two steps: image representation or description and classification. In this paper, we focus on the ...

The micro- and macroscopic fatigue crack growth (FCG) rates of a wide class structural materials were analyzed it was concluded that both coincide either during high-temperature tests or at high stress intensity factor (SIF) values. Their coincidence requires level cyclic deformation the metal along entire front as necessary condition for formation striations (FS). Based on analysis digital fra...

background and objectives: leptospirosis is considered to be the most widespread zoonotic disease in the world and can infect a wide range of animals. although the prevalence of clinical leptospirosis in cats is low, they are probably exposed to leptospires excreted by wild life, rodents etc. this study was performed to determine the serologic reaction of cats to leptospires and their importanc...

background: leptospirosis is a worldwide zoonosis causedby leptospira interrogans. leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. objectives:the aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...
