The purpose of this study was to evaluate the prophylactic effects of quercetin (QUE) against oxidative damages and histological changes induced by 1, 2, 3, 4-tetrachlorodibenzo-p-dioxin (TCDD) in rat heart. For this purpose, 20 adult male Wistar rats were divided into four groups as fellow control group, TCDD group (10µg/kg BW/day by gavage daily for 60 consecutive days), QUE group (30 mg/kg BW/day) and TCDD + QUEgroup. The oxidative biomarkers of heart tissue and the levels of cTnI and lipid profile in serum were measured. Our results showed that the cTnI serum level and the heart lipid peroxidation significantly increased and the heart level of antioxidant profile significantly decreased in the TCDD group compared to control and QUEgroups. While pretreatment with QUEcould significantly improved these factors in serum and heart tissue in animals that consumed TCDD. It can be concluded that QUEat doses of 30 mg/kg/day could alleviate heart oxidative damage and histological changes induced by TCDD.Bifidobacterium selectively colonizes the infants' intestinal tract, and the relevant coliform bacteria in adults are particularly beneficial because of their enhanced capability to prevent pathogens of gastro intestine by direct antimicrobial action and relieve infection, which led to their intensification, the antibacterial activities of titanium nanoparticles producing by some bacteria, makes them attractive as a new agent against pathogenic bacteria. check details In our present study, we used a probiotic bacteria Bifidobacterium bifidum which was isolated from the commercial market capsule to produce TiO2 nanoparticles and study the biologically characterized nanoparticle using various techniques like Scanning Electron Microscopic (SEM), atomic force microscopy (AFM), and study its antimicrobial activity against a bacteria isolated from the stool of patients suffering from acute diarrhea. The results showed that the morphological characteristics of nanoparticles were found to have a spherical shape and mean size of 81 nm by AFM while scanning electron microscope viewed as an oval shape with anatase form synthesized by B. bifidum. TiO2-NP synthesized by B. bifidum had an inhibitory effect against P. aeruginosa, A. baumanii, K. pneumonia at a concentration 16 mg/ml and 32 mg/ml towards E. coli and S. typhi, the minimum inhibitory concentration (MIC) against pathogenic bacteria isolated from acute diarrhea included Pseudomonas aeruginosa, Acinetobacter baumanii, Klebsiella pneumonia, E.coli and salmonella typhi was utilized to determine the antibacterial impact of the synthesized TIO2 nanoparticles. Our biologically synthesized titanium nanoparticles were effective against all the tested pathogenic bacteria at various degrees and had a probable role in significantly greater antimicrobial efficacy against all isolates under study. This trial may have considerable significance for the prevention of antibiotic resistance associated diarrhea in hospitals.In view of the shortcomings of the current abnormal data detection system of the protein gene library, such as low detection rate and high error detection rate, the abnormal data detection system of the protein gene library based on data mining technology is designed. The protein gene enters the firewall module of the system, and enters the immune module when it does not match the firewall rules; the memory detector in the immune module presents the protein gene, if the memory detector does not match the protein gene, the mature detector presents the protein gene, if the mature detector does not match the protein gene, it is determined as the normal protein gene data package, if it matches, it is considered that The abnormal data of protein gene was processed by the collaborative stimulation module, and the control module controlled by C8051F060 chip to detect the abnormal data of protein gene library. The immune module generates new protein gene sequences through an immature detec
