With the spreading of intelligent machines, man-machine communication has become an important research area. Today, intelligent robots co-operating with humans usually have to be able to store, retrieve, and update information about their environment, interpret and execute commands, offer existing and gain/learn new services. In these processes, the efficient knowledge representation and storage are of key importance. In this paper, a new graph based modular knowledge storage and representation form is presented which is able to handle inaccurate and ambiguous information, to store, retrieve, modify, and extend theoretical and practical knowledge, to interpret commands, and to learn new cognitions. © 2014 Springer International Publishing Switzerland.

The objective of this study was to investigate the effect of seven days of feed restriction (between days 42 and 49) on the morphology of the small intestine in experimental rabbit models. Sixty weaned Hyplus rabbits (35 days old) were included in the experiment and split into three groups of 20 rabbits. The first control group (n=20) received feed ad libitum (ADL group), the second (R1) experimental group (n=20) was fed 50 g feed per rabbit per day and the third (R2) experimental group (n=20) received 65 g feed per rabbit per day. Duodenal samples were collected when the rabbits were aged 49, 56, 63 and 70 days. The mean villus height, crypt depth and small intestine length were measured. Significant interactions (P<0.001) between group and age were identified in the villi height and crypt depths. The maximum mean villus height was found in the R2 group in 56‑day‑old rabbits (643.14 µm), while the minimum was found in the ADL group in 49‑day‑old rabbits (460.29 µm). The longest (P<0.001) small intestine was measured in the R1 group in 63‑day‑old rabbits (347.60 cm), while the shortest was measured in the ADL group in 49‑day‑old rabbits (263.60 cm). The models show that villus height, crypt depth and the length of the small intestine change with the intensity of feed restriction and age. © 2014, Spandidos Publications. All rights reserved.

The present study aims to report on the correlation between the degree of negativity of anti-endomysial antibodies and anti-tissue transglutaminase antibodies in the IgA and IgG classes with regard to histological grade, in 44 newly diagnosed children with celiac disease (CD). Samples with negative antibodies, but a positive histology from a 5-year program searching for CD in the pediatric population were collected. A total of 4247 biopsy samples were used in this study. We documented that certain pediatric patients are seronegative, while the disease is active and the incidence of CD is higher than expected in the pediatric population. This is an important finding, which demonstrates the lack of association between autoantibodies and lesions, and justifies the use of biopsies for an accurate CD diagnosis and the importance of revising the diagnostic criteria in a clinical, endoscopic and serological context. We recommend a more active search for incidences of the disease in the pediatric population. Serological markers are not the main method for the diagnosis of CD as they are considered to only have a supporting role clinically. Biopsies of the small intestine are always necessary for the diagnosis of CD in these patients. Source

The aim of this paper is to investigate the zeros of polynomials Pn,k(x) = Kk-1xn + Kkxn-1 +...+ Kn+k-2 x + Kn+k-1, where the coefficients Ki's are terms of a linear recursive sequence of k-order (k ≥ 2). Source
