    Influence of food-derived advanced glycation end products on health
    (Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Galiniak, Sabina; Biesiadecki, Marek
    Introduction. Advanced glycation end products (AGEs) are compounds formed endogenously in the human body. Besides this source of AGEs, they also exist in food and can be generated during cooking. Enhanced endogenous generation and intake of dietary AGEs have physiological impact on human health and are associated with progression of many diseases, including diabetes and its complications. Aim. The purpose of this review is to the present the current state of knowledge about the various negative effects of advanced glycation end products on human health. Materials and methods. This study is based on analysis of literature reporting the content of AGEs in food and high or low AGEs dietary interventions in human and animal subjects. Results. Literature data present databases gathering description of AGEs determinations in various types of food. Conclusions. Excessive consumption of AGEs-rich products, especially abundant in protein and fat or cooked for a long time at high temperature, may contribute to the deterioration of human health, including development of hypertension, insulin resistance, and diabetic complications.

    Receiver operating characteristic analysis of the FeNO biomarker in the diagnosis of asthma
    (Wydawnictwo Uniwersytetu Rzeszowskiego, 2018) Biesiadecki, Marek; Galiniak, Sabina; Bartusik-Aebisher, Dorota; Aebisher, David
    Introduction. The fraction of exhaled nitric oxide (FeNO) is used as a non-invasive biomarker that reflects inflammation in the airways. It is so versatile that it used to control asthma severity as well as to monitor response to treatment. However, the exact cut-off point of the nitric oxide level which allows one to make a precise diagnosis of asthma is unclear. Aim. To examine the possibility of using advanced statistical methods such as receiver operating characteristic for the analysis of FeNO concentrations for improving the diagnosis of asthma. Materials and methods. Receiver operating characteristic (ROC) was used for analyzing results to determine levels of nitric oxide which may be a prognostic indicator of asthma. The studied group consisted of 111 children including 69 asthmatic patients, and 42 age- and sex-matched healthy subjects. Measurement of exhaled nitric oxide was conducted in all subjects included in this study. Results. FeNO level was higher in asthmatic patients. The analysis of results showed that the cut-off point for the FeNO concentration is 11.5 ppb. Sensitivity and specificity with the FeNO level allowed us to determine a value of the diagnostic variable of FeNO concentration of 14.0 ppb. A comparison of FeNO level and sex of the subjects showed there is no correlation between these parameters of patients. Conclusions. Currently, the FeNO measurement provides complementary data in the care of a patient suffering from asthma, however analysis of more studies on a larger group of patients is needed.
