We propose the following extension of Dirac's theorem: if G $G$ is a graph with n ≥ 3 $n\ge 3$ vertices and minimum degree δ ( ) ∕ 2 $\delta (G)\ge n\unicode{x02215}2$ , then in every orientation there Hamilton cycle at least (G)$ edges oriented same direction. prove an approximate version this conjecture, showing that + 8 k $\frac{n+8k}{2}$ guarantees $(n+k)\unicode{x02215}2$ also study analog...

UNLABELLED AUTHORS: Franchi L, Baccetti T. OBJECTIVES The aim of the present study is to evaluate the dentoskeletal features of subjects with either Class II or Class III malocclusions in the mixed dentition using both conventional cephalometric analysis and TPS morphometric analysis applied to posteroanterior (PA) cephalograms. DESIGN TPS analyses of PA cephalograms on 49 Cl-II, and 20 Cl-...

BACKGROUND Prolidase Deficiency (PD) is a rare hereditary disease consisting in developmental delay, mental retardation, facial dysmorphism, splenomegaly, recurrent pulmonary infections and skin lesions. CASE REPORT The present study reports a case of PD treated in the Paediatric Section of the Department of Dentistry and Surgery at the University of Bari. A special diagnostic and clinical ap...

Detection of ABO blood groups through agglutination is the basis of pre-transfusion testing. However, weak agglutination reactions may be obtained with reagent antibodies and are a result of weak expression of A and B antigens on red blood cell surface which may cause a discrepancy in blood group typing. Here, we report a donor which showed discrepancy between red blood cells (forward) and seru...
