Ictal electroencephalography (EEG) parameters in electroconvulsive therapy (ECT) for depression reportedly correlate with therapeutic response and stimulus dosage, particularly right unilateral (RUL) ECT. The authors examined ictal EEG as predictors of effectiveness bilateral (BL) sine pulse wave A total 30 consecutive depressed inpatients who had not responded to standard pharmacotherapy were treated using BL ECT given either or mode. (e.g. regularity, postictal suppression) manually rated...

Abstract This study investigated longitudinal changes and predictive factors for psychological distress among 85 newly diagnosed advanced non‐small cell lung cancer (NSCLC) patients. Whereas tension‐anxiety after diagnosis ( T 1) was significantly reduced at two months 2) six 3) depression‐dejection 1 2, other forms of distress, including anger–hostility, vigor, fatigue, confusion, did not show significant changes. Total mood disturbance change. Only a higher total predictor 3. These...

Background: Substance P (SP) is a multifunctional neuropeptide that transmits pain signals, regulates the immune system, and may modulate emotional stress. SP stimulates bone resorption activity of osteoclasts, level in gingival crevicular fluid correlated with degree periodontal inflammation. However, exact roles metabolism diseases are poorly understood. To elucidate effect stress on metabolism, we investigated osteoblastic cell differentiation presence lipopolysaccharide from...

Several studies have noted modest interrater reliability of clinical electroencephalogram (EEG) interpretations. Moreover, no study to date has investigated a means improve the observed agreement. The purpose present was examine (i). EEG interpretations among three raters (two psychiatrists and one pediatrician); (ii). how by establishing consensus guideline for interpretation. Three raters, two pediatrician, interpreted 100 consecutive recorded at Tajimi General Hospital. After discussing...

Worldwide use of the Hamilton Rating Scale for Depression (HRSD) presupposes that depression symptomatology can be measured same way across countries but no empirical study has yet examined this issue. We therefore cross-cultural consistency factor structure HRSD.A 17-item HRSD data were sought 5,185 individuals diagnosed with major in Japan, Europe and North America. Candidate structures obtained simultaneous component analysis (SCA) three cultures. They then submitted to multiple-group...

Objective: Studies of the cognitive effects electroconvulsive therapy (ECT) have resulted in controversial findings up to now, partly because researchers and reviewers not always made a clear distinction among various aspects cognition there are many parameters involved administration ECT that potential impact on cognition. The present study focused sine pulse waveforms anterograde memory nonmemory functions. Methods: We assigned 18 patients with unipolar major depression or bipolar I II...

Boron neutron capture therapy (BNCT) is a promising modality for cancer treatment because of its minimal invasiveness. To maximize the therapeutic benefits BNCT, development efficient platforms delivery boron agents indispensable. Here, carborane-integrated immunoliposomes were prepared via an exchanging reaction to achieve HER-2-targeted BNCT. The conjugation anti-HER-2 antibody liposomes successfully endowed these with targeting properties toward HER-2-overexpressing human ovarian cells...
