The present work proposes a unified model to explain two previously reported properties of the Mach band illusion. The first is the frequently referenced fact that Mach bands are prominently visible at ramps, but practically vanish at intensity steps. The second property, less studied, on the other hand may also be related to the first. It concerns the fact(More)
Recently, we have demonstrated, immunization of adult female mice with outer membrane vesicles (OMVs) of Shigella boydii type 4 protected their offspring passively from shigellosis. In our present study, we have advanced our research by formulating multi-serotype outer membrane vesicles (MOMVs), mixing the OMVs of Shigella dysenteriae 1 Δstx, Shigella(More)
Like most other Gram-negative bacteria, Shigella releases outer membrane vesicles (OMVs) into the surrounding environment during growth. In this study, we have exploited OMVs of Shigella as a protective immunogen in a mice model against Shigellosis. Distinctive vesicle secretion was noticed from different Shigella strains. Among them, Shigella boydii type 4(More)
Recently we have shown the homologous protective efficacy of heat killed multi-serotype Shigella (HKMS) immunogens in a guinea pig colitis model. In our present study, we have advanced our research by immunizing rabbits with a reduced number of oral doses and evaluating the host's adaptive immune responses. The duration of immunogenicity and subsequently(More)
This paper shows how the most important features can be selected from the face so that the performance of any face recognition engine can be improved by matching only the maximally distinguishable features. Creating an automated face recognition system that can duplicate human performance in recognizing a face is one of the key goal of computer vision(More)
Recently, we demonstrated oral immunizations with single serotype outer membrane vesicles of Vibrio cholerae induced serogroup specific protective immunity in the RITARD model. In our present study, we advanced our research by formulating multi-serotype outer membrane vesicles, mixing the OMVs of five virulent V. cholerae strains. Four doses of oral(More)
In this study, the extract of a green leafy vegetable Oxalis corniculata (Oxalidaceae) was evaluated for its in vitro antibacterial and in vivo anti colonizing effect against common intestinal pathogenic bacteria. Methanolic extract (80%) of Oxalis corniculata (Oxalidaceae) leaf contained a polyphenol content of 910 mg gallic acid equivalent per gram of dry(More)
