Study of Electrochemical Processes with Coupled Homogeneous Chemical Reaction in Differential Pulse Voltammetry at Spherical Electrodes and Microhemispheres

ELECTROANALYSIS, Issue 16 2010
Eduardo Laborda
Abstract Homogeneous chemical reactions coupled to oxidation-reduction processes at electrode surfaces are very common in electrochemistry. In this paper we cope with the application of Differential Pulse Voltammetry at spherical electrodes and microhemispheres for the study of this kind of systems. Analytical expressions are deduced from which the influence of the different experimental variables is examined. Several diagnostic criteria for elucidation of the reaction mechanism from DPV peak parameters are given, as well as working curves for extraction of the kinetic rate constants of the chemical reaction.

Withdrawal behavior and depression in infancy

INFANT MENTAL HEALTH JOURNAL, Issue 4 2007
Antoine Guedeney
This paper describes the history of the concept of infant depression, which has been at the beginning of the discipline of infant mental health, and reviews classification and diagnosis issues, along with some animal models. Several diagnostic criteria have yielded different prevalence rates, and some being unrealistic, but we still do not know when infant depression begins, what its outcome is, and what are its different aspects. It is suggested that infant depression needs a certain amount of emotional and cognitive development to unfold, and that it might not exist before 18,24 months of age, a crossover during which major autoreflexive, cognitive, and emotional abilities emerge. Depression could be an outcome of attachment disorganization in infancy, as depression and disorganization seem to share the same learned helpnessness psychopathological process. Developmental psychopathology considers trouble more from a dimensional point of view rather than from a categorical one, and more as the result of several factors with a sequential action rather than the effect of a genetic disorder with direct expression. Before the limit of 18,24 months, the concept of relational withdrawal seems more applicable and useful. [source]

Validation of diagnostic criteria for sleep bruxism

JOURNAL OF ORAL REHABILITATION, Issue 9 2002
K. BABA
Several diagnostic criteria for bruxism can be taken from the literature; however, most of them have never been validated. This study examined whether predictor variables taken from physical examinations and questionnaires were related to the actual bruxism levels. Fifty dental students agreed to participate in this study and eight examination variables and seven questionnaire variables were collected from them. The subjects measured their nocturnal EMG activity from the right masseter muscle for six consecutive nights in their home by means of a portable EMG device. Off-line analysis was performed on data from second to sixth nights. By using a custom made software, all EMG activity elevations above a minimum threshold of 50% of each subject's individually established maximum voluntary contraction (MVC) level were quantified with regard to the duration and number of elevations and then three outcome variables, which were event number per hour (number/h), event duration per hour (duration h,1), and duration per event (duration/event), were calculated. A multiple stepwise regression (MSR) analysis was conducted to assess the 15 predictor variables and the three outcome variables. These MSR analyses revealed that the joint sound score remained in the regression equation as a predictor (n=50, P < 0·05) of the likelihood that a subject would exhibit longer bruxism events (duration h,1and number h,1). It must be noted that the self-awareness and tooth attrition status were found not to be strong predictors and even for the above variable where significant association was found, the likelihood ratio between the variable and predicted outcomes was not robust.

European Federation of Neurological Societies/Peripheral Nerve Society Guideline, on management of multifocal motor neuropathy.

JOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 1 2006
Report of a joint task force of the European Federation of Neurological Societies, the Peripheral Nerve Society
Abstract Background: Several diagnostic criteria for multifocal motor neuropathy (MMN) have been proposed in recent years, and a beneficial effect of intravenous immunoglobulin (IVIg) and various other immunomodulatory drugs has been suggested in several trials and uncontrolled studies. Objectives: The aim of this guideline was to prepare consensus guidelines on the definition, investigation, and treatment of MMN. Methods: Disease experts and a representative of patients considered references retrieved from MEDLINE and the Cochrane Library in July 2004 and prepared statements that were agreed in an iterative fashion. Recommendations: The Task Force agreed on good practice points to define clinical and electrophysiological diagnostic criteria for MMN and investigations to be considered. The principal recommendations and good practice points were as follows: (1) IVIg (2 g/kg given over 2,5 days) should be considered as the first line of treatment (level A recommendation) when disability is sufficiently severe to warrant treatment; (2) corticosteroids are not recommended (good practice point); (3) if initial treatment with IVIg is effective, repeated IVIg treatment should be considered (level C recommendation). The frequency of IVIg maintenance therapy should be guided by the individual response (good practice point). Typical treatment regimens are 1 g/kg every 2,4 weeks or 2 g/kg every 4,8 weeks (good practice point); (4) if IVIg is not (or not sufficiently) effective, then immunosuppressive treatment may be considered. Cyclophosphamide, cyclosporine, azathioprine, interferon-,1a, or rituximab are possible agents (good practice point); and (5) toxicity makes cyclophosphamide a less desirable option (good practice point).
