background: leptospirosis is the most common zoonosis widespread in tropical and temperate countries with low social-economic status. we aimed to compare an elisa kit with an in-house elisa assay to test the serum samples of the patients who were suspicious of leptospirosis according to their clinical symptoms.   methods: a total of 282 serum samples of patients suspicious of leptospirosis admi...

Botulism is caused by the neurotoxins (BoNTs) produced from Clostridium botulinum. These neurotxins often lead to fatal neuroparalytic disease which is regarded a major threat to the public health. For this reason, rapid and reliable diagnosis of BoNTs in field settings and peripheral care centers is highly valuable. Here, we describe a multiplexed and sensitive optical immunoassay (OIA) for th...

in the first part of this paper, some theorems are given for a riemannian manifold with semi-symmetric metric connection. in the second part of it, some special vector fields, for example, torse-forming vector fields, recurrent vector fields and concurrent vector fields are examined in this manifold. we obtain some properties of this manifold having the vectors mentioned above.

The semi-micro method for interferon assay was based on quantitation of inhibition of cytopathic effects in 6-mm wells. Cultures were exposed to interferon dilutions, challenged with vesicular stomatitis virus, and stained with methylrosanaline chloride. The bound dye was then eluted and measured colorimetrically. The method was more sensitive than the plaque-inhibition method and was extremely...

Classifying large datasets without any a-priori information poses a problem especially in the field of bioinformatics. In this work, we explore the problem of classifying hundreds of thousands of cell assay images obtained by a highthroughput screening camera. The goal is to label a few selected examples by hand and to automatically label the rest of the images afterwards. We deal with three ma...
