With the advent of smart car and even driverless cars, the importance of intelligent driver’s system has been rapidly growing. Accordingly, driver’s vision has become one of the most popular issues and especially detecting some obstacles and pedestrians on the road are at the center of the vision problem in order to prevent accidents. Motivated by the importance of such topics, we implemented t...

From optimizing a car’s performance, encouraging safer driving to accurate insurance pricing, it is desirable to be able to identify a driver by his driving style. Using a car data supplied by MetroMile Inc., driving styles were analyzed and core features were extracted. Two learning models were investigated and evaluated:support vector machine (SVM) and multinomial logistic regression. High ac...

hepatitis b surface antigen is the first genetically engineered vaccine licensed for human use. various strategies have been proposed to obtain a vaccine that would bypass the need for injection. in this study, a non-toxic portion of heat-stable enterotoxin of escherichia coli that is capable of adhering to epithelial cells was inserted at amino acid position 112 of hepatitis surface antigen. t...

background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...

Different mutants of an infectious full-length clone (p35PPV-NAT) of Plum pox virus (PPV) were constructed: three mutants with mutations of the assembly motifs RQ and DF in the coat protein gene (CP) and two CP chimeras with exchanges in the CP core region of Zucchini yellow mosaic virus and Potato virus Y. The assembly mutants were restricted to single infected cells, whereas the PPV chimeras ...

Cassette vectors have been constructed for mammalian expression of complete immunoglobulin heavy and light chain genes whose variable regions are produced by the polymerase chain reaction (PCR). The light and heavy chain vectors have promoter, leader, partial intron, enhancer and constant region segments within modified pSV2-gpt and pSV2-neo plasmids, respectively. Variable (V) regions are obta...

Hantavirus glycoprotein Gc is one of the main components that contribute to the generation of humoral immune responses, while the nucleocapsid protein (NP) is involved in cellular immune responses through the induction of antibody-dependent cytotoxic T cells. In this study, a chimeric gene, GcS0.7, which encodes a fusion protein containing Gc and truncated NP, was constructed as a candidate for...

We have developed a universally applicable system for conditional gene expression in embryonic stem (ES) cells that relies on tamoxifen-dependent Cre recombinase-loxP site-mediated recombination and bicistronic gene-trap expression vectors that allow transgene expression from endogenous cellular promoters. Two vectors were introduced into the genome of recipient ES cells, successively: (i) a bi...

Mapping vectors containing antibiotic resistance markers inserted adjacent to or within different cloned genes from Streptococcus mutans were used to determine the relative positions of these genes on the chromosome. The gtfA, ftf, and scrB genes were inserted into streptococcal mapping vector pVA891 adjacent to an Emr gene, whereas the Emr marker was inserted directly into the gtfB gene. These...

Chimeric proteins resulting from characteristic chromosomal translocations are believed to play a key role in the development of neoplasia. The consistent chromosomal translocation t(12;22) found in Clear Cell sarcoma (CCS) fuses the genes for Ewing's sarcoma protein (EWS) and activating transcription factor 1 (ATF1). Contribution of the chimeric EWS/ATF1 protein to maintenance of the tumor phe...
