The aim of the present study was to investigate whether Jerusalem artichoke powder produced by a simple drying method is suitable for replacing inulin as a dietary fibre in bread. Baking probe was performed using 0, 5, and 10% Jerusalem artichoke (JA) powder and 2.5 and 5% inulin (IN) on wheat flour weight basis. Functional properties of bread loafs were tested by Stable Micro System TA TX2i Texture Analyser (SMS) after 0, 24, 48, and 72 h storage. It was concluded that using inulin as a dietary fibre did not deteriorate the baking quality of bread, however, shelflife slightly decreased. Jerusalem artichoke powder compared to inulin had similar effect on the baking properties of bread. Based on our results, JA powder proved to be a promising alternative for fibre enhancement in bread.
An important obstacle to achieve optimal glycaemic control in diabetics on intensive insulin therapy is the frequent occurrence of insulin induced hypoglycaemic events. In healthy subjects and in diabetics without autonomic neuropathy hypoglycaemia activates the sympathetic nervous system, resulting in epinephrine and glucagon release. Both hormones increase hepatic glucose production and this counterregulatory response is of key importance of glucose homeostasis. Recent research shed light on the fact that antecedent hypoglycaemic episodes play pivotal role in hypoglycaemia associated autonomic failure (HAAF). In this condition the sympatho-adrenal response to decreased blood glucose level is blunted. The existence of HAAF clearly indicates that the nervous system contributes to glucose homeostasis in a substantial manner. This review outlines the mechanisms of both peripheral and central neuronal glucose sensing and of neural pathways involved in the counterregulatory response.
The first version of the map of the Hungarian vegetation-based landscape regions were prepared at the scale of 1: 200,000 (1 km or higher resolution). The primary goal of the map was to provide an exact background for the presentation and evaluation of the data of the MÉTA database. Secondly, we intended to give an up-to-date and detailed vegetation-based division of Hungary with a comprehensive nomenclature of the regions. Regions were primarily defined on the basis of their present zonal vegetation, or their dominant extrazonal or edaphic vegetation. Where this was not possible, abiotic factors that influence the potential vegetation, the flora were taken into consideration, thus, political and economical factors were ignored. All region borders were defined by local expert botanists, mainly based on their field knowledge. The map differs in many features from the currently used, country-wide, flora-or geography-based divisions in many features. We consider our map to be temporary (i.e. a work map), and we plan to refine and improve it after 5 years of testing.
