Emotional dysregulation is a complex pattern of reactivity to reality stimuli that now can be empirically studied. The dysregulation of emotion rating scale (DERS, Gratz and Roamer, 2004 ) seems tobea good instrument to evaluate the components and the phases of the process of emotional dysregulation. In this presentation, the data from Italian clinical and non-clinical population will be discussed. Clinical subjects will be: borderline personality disorder BPD obesity with binge eating obesity without binge eating. Preliminary data concerning the process of emotional reactivity, after the presentation of emotionally significant video clips in borderline patients, will be presented, too. The main interest of this data is to compare different patterns of emotional dysregulation in different clinical populations.

Results of asymptotic stability and instability for nonautonomous differential systems with unbounded right hand side are obtained by using several auxiliary functions and topological properties of the @W-limit set of solutions. The theorem established is applied to prove the asymptotic stability of the stationary solution of the Lienard equation with unbounded dampings.

The β-hexosaminidase (EC 3.2.1.30)isoenzymes were separated on the basis of their carbohydrate moieties by an affinity chromatography using immobilized phenylboronate. Normal lymphocytes and granulocytes contain two major forms of β-hexosaminidase. acute lymphoblastic, acute myeloblastic, chronic lymphocytic and chronic myelocytic leukemic cells contain an extra, distinct isoenzyme of β-hexosaminidase. This extra isoenzyme may be a marker for the leukemic conversion of hematopoietic tissue.

β-N-Acetyl-d-glucosaminidase and its kinetic characteristics were determined in serum and skin from both diabetes mellitus and impaired glucose tolerance patients and controls. Mean total activity was reduced (p < 0.05) in the skin of both patient groups. β-N-Acetyl-d-glucosaminidase isoenzyme expression was investigated using chromatofocusing on PBE-94 coupled with automated enzyme assay. The isoenzyme profiles from serum showed two major forms (A and B) whose ratio varied from 2:1 in controls to 3:1 in diabetics. Moreover, diabetes mellitus and impaired glucose tolerance subjects displayed an intermediate (I) form. The A/B isoenzyme ratio was completely reversed in skin.
