Genetically modified foods (GM foods) have revolutionized the agricultural industry towards more proficient farming in every geographical region of the world. The major tasks of this GM food technology could be summarized in four points including increase in food products, more convenient food processing, disease prevention and treatment and avoiding of using pesticides through the generation of pest-resistant crops. Although the GM foods technology had great advantages for human health, there are some concerns regarding biodiversity induced by modified plants, which can indirectly affect human being, as well. Further studies are warranted to define precisely the status of this technology in ecosystem in which human is living.

Novel concepts of smart/intelligent, active and eco-friendly food packaging systems, are getting much more attention these days. There have been new functionalities ascribed to the packaging, mostly derived from recent consumer's request for organic and clean-label –high-quality products. This paper throws light on the current advances in antimicrobial active packaging of fresh meat and meat-based products. Among the classes of antimicrobials proposed and tested with remarkable antimicrobial power against microorganisms involved in meat spoilage and meat-borne diseases, we focused on plant-derived essential oils (EOs) and nanoparticles (NPs) as they were attractive meat protecting agents according to the literature review, we have made. The various technologies and methods for incorporating antimicrobial compounds into the package including embedding for controlled release, immobilization, and layer-by-layer deposition, photographting and their feasible approach for active meat packaging are surveyed and scrutinized.

Abstract
The purpose of this study was to evaluate the validity of a BIA device, Xiaomi MI, against X-scan plus 970. A total of 30 university students and employees (18 women and 12 men) aged between 19 and 50 years were selected. Weight and body composition were measured using Xiaomi MI and X-scan plus 970. ...

The purpose of this study was to evaluate the validity of a BIA device, Xiaomi MI, against X-scan plus 970. A total of 30 university students and employees (18 women and 12 men) aged between 19 and 50 years were selected. Weight and body composition were measured using Xiaomi MI and X-scan plus 970. The mean age of subjects was 28.9±9.1 for men and 30.4±9.4 for women. There was a strong correlation between X-scan plus 970 and Xiaomi MI scale 2 results (p<0.000). Our results suggest that Xiaomi MI scale 2 is a valid device to measure body composition which makes it appropriate for clinical use.

In Gram-positive bacteria, the production of extracellular vesicles has been neglected to date due to the presence of a thick peptidoglycan cell wall. But in recent years more studies have been done on these nanoparticles. The purpose of this study is to show that Lactobacillus casei has the ability to produce extracellular vesicles. Since extracellular vesicles (EVs) are an important agent to mediate the expression of genes. In this scientific research, we have examined to find out the effect of EVs derived from L. casei on the expression of Toll-like receptor 2 gene. The EVs were purified from the conditioned medium of L. casei using ultracentrifugation and confirmed by scanning electron microscopy (SEM). The Caco2 cells were treated with different concentrations of purified extracellular vesicles. The electron microscopy showed spherical vesicles that had an average diameter of 200nm. The extracted protein content was 2.4 in the ultracentrifugation method. It was determined that the extracellular vesicles of this bacterium at concentrations of 150 μg/ml had no significant effect on the expression of Toll-like receptor-2 gene expression in comparison with the control (Sucrose), whereas the expression of this gene in the treatment of EVs at concentrations of 50 and 100 μg/ml decreased. Our result creates a paradigm for future studies of the functional component from gut microbiota as a new possible dietary supplement instead of probiotic.

Pediatric obesity is going to be one of the major risk factors in our era. It might have adverse effects on all aspects of child’s health. It could affect both physically and mentally and cause emotional suffering as well. It is shown that obesity could decrease cognition, but its relationship with emotional intelligence (EI) is unclear. In this cross-sectional study, the relationship between the child’s weight and level of EI has been investigated. Seventy-one children with average age 9.2±2.3 years old (32 girls and 39 boys) of volunteer parents who have come to counseling clinic were joined in this study. Anthropometrical information of children including BMI for age Z score was analyzed by using Anthro Plus software. Demographic information such as gender, year of birth, household income, and parental educational status were obtained by using common SES questionnaire. Emotional intelligence of children was obtained by using “Trait Emotional Intelligence Questionnaire – Child Short Form” (TEIQue-CSF). A significant negative correlation between BMI and EI score was seen in both genders (r2=0.33, p=0.001). A similar pattern was also noticed for both boys and girls. Despite the similarity of this pattern in both genders, to some extent boys showed a stronger negative relationship between their BMI and EI score (Girls: r2=0.293, p=0.001; Boys: r2=0.388, p=0.001). Based on the present study, overweight and obesity are associated with a higher EI score in both genders, which shows the importance of weight effect on EI.
