Class III Treatment with Skeletal and Dental Anchorage: A Review of Comparative Effects.

Objectives: This review addresses the comparative effects of skeletal anchored maxillary protraction (MP) versus dental anchored MP.

Materials And Methods: The studies retrieved had to have both test and control groups treated by the use of a facemask with or without the use of skeletal anchorage though either (palatal/buccal) maxillary or mandibular miniscrews/miniplates, respectively.

Results: Nine articles were included.

Neurological soft signs and cerebral measurements investigated by means of MRI in schizophrenic patients.

Neurophysiologic research has shown a Neurological Soft Sign (NSS) characteristic prevalence in schizophrenic patients, and correlations between NSS and the most frequently cerebral alterations. The aim of this study was to investigate, by means of MRI, the quantitative alterations of cortical and subcortical structures and their correlation with NSS in a sample of schizophrenic patients. Linear measures of lateral ventricular (Evans ratio), third ventricular (Third Ventricular Width), hippocampal (Interuncal Index) and cerebellar (Verm Cerebellar Atrophy) atrophy were made on magnified MR images of 33 patients with a DSM IV diagnoses of chronic schizophrenia.

NMR-based metabolic profiling of human hepatoma cells in relation to cell growth by culture media analysis.

Metabolic profiling is a metabolomic approach that allows the characterization of metabolic phenotypes under specific set of conditions. In the present paper we investigated the metabolism of sparse and high density cultures in relation to different cell growth phases. Changes in the metabolome were evaluated by using 1H-NMR spectroscopy, correlation map and Multivariate Data Analysis on the net balances of metabolites in the medium.

Zebrafish embryo proteins induce apoptosis in human colon cancer cells (Caco2).

Previous studies have shown that proteins extracted from Zebrafish embryo share some cytostatic characteristics in cancer cells. Our study was conducted to ascertain the biological properties of this protein network. Cancer cell growth and apoptosis were studied in Caco2 cells treated with embryonic extracts.

Neurologic soft signs in schizophrenic patients treated with conventional and atypical antipsychotics.

Neurologic soft signs (NSS) are considered a somatic feature associated with schizophrenia (DSM-IV) that are present in neuroleptic-treated, as well as untreated or first-episode patients. The aim of this study was to determine the incidence and severity of NSS in groups of schizophrenic patients treated with either a conventional neuroleptic medication, haloperidol (n = 37), or atypical antipsychotic medications, risperidone (n = 19), clozapine (n = 34), and olanzapine (n = 18). NSS were assessed with the Neurological Evaluation Scale (NES), whereas extrapyramidal symptoms (EPS), which occur more commonly with conventional neuroleptic treatment, were evaluated using the Simpson-Angus Scale.

Deficit of executive functions in schizophrenia: relationship to neurological soft signs and psychopathology.

Cognitive deficits and neurological soft signs (NSS) have frequently been reported in schizophrenic patients and they both appear related to prominent negative symptoms. The aim of the present study was to examine the relationship between deficit of executive functioning, assessed by the Wisconsin Card Sorting Test (WCST), NSS and psychopathological dimensions of schizophrenia in order to address the issue of whether a typology of schizophrenic patients may be identifiable by clinical, neurological and neuropsychological features. A sample of 26 male schizophrenic patients was divided, on the basis of the performance on the WCST, into two subgroups ('good performers' and 'poor performers') that were compared for the prevalence and severity of NSS, assessed by the Neurological Evaluation Scale (NES), and for the psychopathological features, assessed using the Positive and Negative Syndrome Scale (PANSS).
