Abstract:
Perilla fruit oil (PFO) is rich in α-linolenic acid and phytochemicals that are beneficial for health. We aimed at preparation of PFO-supplemented soybean milk (PFO-SM) and assessment for health outcomes of PFO-SM drink in humans. PFO-SM was prepared by adding PFO in SM (1% v/v) along with other ingredients, pasteurized and determined nutritional facts using our established protocol. Healthy subjects were randomly divided into three groups (n = 48 each); deionized water (DI), SM and PFO-SM, and consumed the products after breakfast and dinner every day for 30 d. Health indices were recorded and blood were collected on days 0 and 30 for measuring levels of hematological, biochemical and oxidative stress parameters. Consumptions of PFO-SM and SM did not influence values of body weight, body mass index, blood pressure and complete blood counts.

Abstract:
Bacteriocin can be defined as ribosomal synthesized antimicrobial polypeptides or proteins secreted by bacteria chiefly by lactic acid bacteria. Natural food preservation is the method in which we use naturally produced antimicrobial compounds or normal-flora as a food preservative to prevent food spoilage microorganisms and to extend food shelf life. Currently, some ambitious rational motives like augmentative of consumers demand to get a new and fresh like foods, potential health hazards of artificial food preservative and accumulation of irrepressible food additive have to lead to the development of an alternative food preservation technology to maintain the freshness of food products. Therefore, bacteriocins are emerging as the very likely natural alternative preservative to chemical preservative and widely accepted as safe food preservative though out worldwide. Due to consumers’ demand and awareness on health effect and benefits of fermented foods and strict government legislation on foods , applications of bacteriocins novel natural food preservative initiates searching for the design of novel technologies used in the food industry. Therefore, the main objective of review paper is to explore the general background and application of bacteriocin as a novel and promising food preservative.

Abstract:
Bovine mastitis is the most common infectious disease in dairy cattle with major economic implications for the dairy industry worldwide. Continuous monitoring for the emergence of antimicrobial resistance (AMR) among bacterial isolates from dairy farms is vital not only for animal husbandry but also for public health. In this study, the prevalence of AMR in 113 Escherichia coli isolates from cases of bovine clinical mastitis in Canada was investigated. Kirby-Bauer disk diffusion test with 18 antibiotics and microdilution method with 3 heavy metals (copper, zinc, and silver) was performed to determine the antibiotic and heavy-metal susceptibility. Resistant strains were assessed for efflux and ß-lactamase activities besides assessing biofilm formation and hemolysis. Whole-genome sequences for each of the isolates were examined to detect the presence of genes corresponding to the observed AMR and virulence factors. Phenotypic analysis revealed that 32 isolates were resistant to one or more antibiotics and 107 showed resistance against at least one heavy metal. Quinolones and silver were the most efficient against the tested isolates. Among the AMR isolates, AcrAB-TolC efflux activity and ß-lactamase enzyme activities were detected in 13 and 14 isolates, respectively. All isolates produced biofilm but with different capacities, and 33 isolates showed α-hemolysin activity. A positive correlation (Pearson r = +0.89) between efflux pump activity and quantity of biofilm was observed. This investigation showed the prevalence of AMR in E. coli isolates from bovine clinical mastitis and suggest the inadequacy of antimicrobials with a single mode of action to curtail AMR bacteria with multiple mechanisms of resistance and virulence factors. Therefore, it calls for combinatorial therapy for the effective management of AMR infections in dairy farms and combats its potential transmission to the food supply chain through the milk and dairy products.

Title: Effect of Vitamin E (alfa-tocopherol) Supplementation on Hemato-biochemical Profile of Race Stallions Horses
Biography:
Nahla Mohamed Ahmed Ibrahim graduated with a Bsc degree First Class in Mathematics and Computer Science, Faculty of Mathematical Sciences, Khartoum University(Sudan) and a Postgraduate Diploma in Mathematics, African Institute for Mathematical Sciences (AIMS).
Abstract:
This study was conducted with the objective of determining the effect of vitamin E (α-tocopherol) supplementation on hemato-biochemical Parameters of stallion race horses in Khartoum State. The field study was carried out using 21 animals of gelding stallions race horses, thoroughbred, with average body weight 300 ± 60 kg and average age was 7 years. The horses were housed in three stables and all animals were fed green alfalfa and concentrates twice a day. The concentrate was supplemented with three levels of Vitamin E (0, 2000 IU, 3000 IU kg /feed) and 7animals were a assigned for each treatment. The experiment was carried out in two periods, the first during the period from November to December 2016 and the second from March to April 2017. Blood samples were collected from the jugular vein at the end experiments in both winter and summer season. Blood samples and serum were used to determine hemato-biochemical parameters.
