cryptosporidiosis is a gastroenteric disease caused by the protozoan parasite cryptosporidium parvum. water–borne transmission of this organism has become more prevalent in recent years. current method for detection of c. parvum oocysts in water is immunofluoresence assay (ifa). the method is time consuming, laborious and particularly not–specific. it cannot determine the infectivity of detecte...

rust caused by phakopsora pachyrhizi syd. is a major constraint to soybean product in asia. early detection and possibilities of controlling plant diseases by the integration of several image processing methods has been the subject of extensive research. the main contribution of this paper is to present different methodologies for quantitatively detecting soybean rust at each stage of disease d...

DESIGN: Although the ThinPrep Pap Test is replacing conventional Pap smears in many clinical practices, experience with the identification of glandular lesions is limited. In this study, ThinPrep cytology of glandular lesions was evaluated in a large, inner city teaching hospital with high rates of glandular abnormality. STUDY DESIGN: Six months of ThinPrep diagnoses in 1998, following nearly 1...

colorectal cancer remains one of the major cancer- related deaths despite progress in the treatment during past decades. detection of disease at earlier stages reduces its mortality. the aim of current study was to investigate expression of cytokeratin 19 (ck19), cytokeratin 20 (ck20) and guanylyl cyclase c (gcc) mrna in peripheral blood of non- metastatic colorectal cancer patients which may r...

introduction breast cancer is one of the most life-threatening conditions among women. early detection of this disease is the only way to reduce the associated mortality rate. mammography is a standard method for the early detection of breast cancer. today, considering the importance of breast cancer detection, computer-aided detection techniques have been employed to increase the quality of ma...

automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...

this paper demonstrates design and fabrication o f a mechatronic system for human drowsiness detection. this system can be used in multiple places. for example, in factories, it is used on some dangerous machinery and in cars in order t o prevent the operator o r driver from falling asleep. this system is composed of three parts: (1) mechanical, (2) electrical and (3) image processing system. a...

The importance of nanotechnology in medical technologies, especially biomedical diagnostics, is indubitable. By taking advantages of nanomaterials, many medical diagnostics methods have been developed so far, including electrochemical nanobiosensors. They have been used for quantification of different clinical biomarkers for detecting, screening, or follow up a disease. microRNAs (miRNAs) are o...

conclusions development of novel drugs and diagnostic tests has allowed us to better manage vl. although leishmaniasis is one of the oldest known parasitic infectious diseases, increasing prevalence of vl among specific populations, recent reports of disease reactivation and flare-up in clinically asymptomatic patients after the onset of immunosuppressive therapy, the risk of disease acquisitio...
