متن کاملProduction and Characterization of Monoclonal Antibodies Recognizing a Common 57-kDa Antigen of Leishmania Species
Background: The therapy of leishmania infection is difficult and each year 1.5 million new cases of cutaneous leishmaniasis and 500,000 new cases of visceral leishmaniasis are estimated, therefore, there is a need for an effective vaccine. Monoclonal antibody (mAb) is one of the suitable methods for isolation and purification of leishmania antigens. In this report, we produced several mAb aga...
متن کاملMonoclonal antibody recognizing a species-specific protein from Streptococcus pneumoniae.
Monoclonal antibodies (MAbs) against a nonencapsulated strain (R36A) of Streptococcus pneumoniae were produced to aid in a search for antigens common to this species. By Western immunoblot analysis, a species-specific 37-kilodalton (kDa) protein was found in lysates of 24 different encapsulated strains of S. pneumoniae. Monoclonal antibodies against the 37-kDa antigen did not react with 55 hete...
متن کاملA Hierarchical Method of Recognizing Plant Species by Leaf Shapes
In order to recognize plant species from their shapes, shapes of contours of leaves can be used. However, contours of leaves are complicated and have variations. In order to deal with the complexities and variations of contours of leaves, a hierarchical representation of leaves is presented in this paper. First, global structures and shapes of leaves are represented by polygons whose vertices a...
متن کاملRecognizing Bird Species in Audio Files Using Transfer Learning
In this paper, a method to identify bird species in audio recordings is presented. For this purpose, a pre-trained Inception-v3 convolutional neural network was used. The network was fine-tuned on 36,492 audio recordings representing 1,500 bird species in the context of the BirdCLEF 2017 task. Audio records were transformed into spectrograms and further processed by applying bandpass filtering,...
