We examined the efficacy and safety of electroshock therapy (EST) under general anesthesia in 26 depressed patients (9 males, 17 females, age range 55-79). The scores of the Hamilton Psychiatric Rating Scale for depression were significantly decreased after EST and clinical symptoms such as depressive mood. psychomotor retardation, anxiety, agitation, suicidal tendencies, hypochondria and sleeplessness improved in all of the patients. Complications included amnesia (16/26), delirium (3/26) and transient arrhythmia (1/26) after EST, but neither lethal nor lasting complications were observed. In summary, EST was an effective and convenient method of treatment for senile depression.

A senile patient showed a dramatic recovery from medication-resistant depression after non-convulsive electroshock therapy (nc-EST), with a lasting change in response to trazodone, which mainly acts as a serotonin re-uptake inhibitor. This result suggests that a change in the serotonin reuptake mechanism may be involved in the effect of nc-EST on depression.

We describe the case of a patient with coronary artery disease who developed transient ST-segment depression, right bundle branch block (RBBB), left anterior hemiblock, ST-segment elevation +ST), and "giant" T-waves in her electrocardiogram (ECG), an assortment of ECG patterns heretofore unreported in conjunction with exercise stress testing (EST). The amplitude of the +ST was modulated by the superimposed RBBB, as was shown by its augmentation after the abrupt disappearance of RBBB. Following recession of the latter "giant" T-waves, which usually are encountered in the hyperacute phase of myocardial infarction, developed and persisted late in the recovery period. Cardiac enzymes after EST were negative, and arteriography revealed a stenotic left anterior descending coronary artery. The present case indicates that a variety of ECG expressions of severe transmural ischemia or myocardial infarction can also be manifest in the course of EST; this also suggests a common pathophysiological mechanism in severe EST-triggered ischemia and the early phase of myocardial infarction.

Nitroglycerine (NTG) is still the most important angina relief drug. The aim of the study was to evaluate clinical effects and tolerance of sublingually nitroglycerine sub form Nitromint-spray in patients with exercise induced angina pectoris (AP) using treadmill electrocardiography stress test (EST). The study group consisted of 40 adults patients (mean age 57.4 +/- 10.08 years) hospitalised in our clinic with AP confirmed by clinically and electrocardiographically positive EST. Tests were performed using treadmill Marquette-Centra equipment, according to the modified Bruce protocol after 3 days wash-out period. On the fourth day two ESTs were performed: EST-0 and 30 minutes later EST-NTG after sublingual administration 0.8 mg of NTG. Among measured parameters after NTG exercise induced ST segment depression decline from 2.3 +/- 1.0 to 1.5 +/- 0.8 (p < 0.0001). EST after NTG became electrocardiographically negative in 11 patients. NTG increased workload, and time to angina pain oneset (p < 0.0001). Nitromint-spray proved to be clinically effective, well tolerated and easy to use.

Alterations in transcription, RNA editing, translation, protein processing, and clearance are a consistent feature of Alzheimer's disease (AD) brain. To extend our initial study (Alzheimer Reports [2000] 3:161-167), RNA samples isolated from control and AD hippocampal cornu ammonis 1 (CA1) were analyzed for 12633 gene and expressed sequence tag (EST) expression levels using DNA microarrays (HG-U95Av2 Genechips; Affymetrix, Santa Clara, CA). Hippocampal CA1 tissues were carefully selected from several hundred potential specimens obtained from domestic and international brain banks. To minimize the effects of individual differences in gene expression, RNA of high spectral quality (A(260/280) > or= 1.9) was pooled from CA1 of six control or six AD subjects. Results were compared as a group; individual gene expression patterns for the most-changed RNA message levels were also profiled. There were no significant differences in age, postmortem interval (mean < or = 2.1 hr) nor tissue pH (range 6.6-6.9) between the two brain groups. AD tissues were derived from subjects clinically classified as CDR 2-3 (CERAD/NIA). Expression data were analyzed using GeneSpring (Silicon Genetics, Redwood City, CA) and Microarray Data Mining Tool (Affymetrix) software. Compared to controls and 354 background/alignment markers, AD brain showed a generalized depression in brain gene transcription, including decreases in RNA encoding transcription factors (TFs), neurotrophic factors, signaling elements involved in synaptic plasticity such as synaptophysin, metallothionein III, and metal regulatory factor-1. Three- or morefold increases in RNAs encoding DAXX, cPLA(2), CDP5, NF-kappaBp52/p100, FAS, betaAPP, DPP1, NFIL6, IL precursor, B94, HB15, COX-2, and CEX-1 signals were strikingly apparent. These data support the hypothesis of widespread transcriptional alterations, misregulation of RNAs involved in metal ion homeostasis, TF signaling deficits, decreases in neurotrophic support and activated apoptotic and neuroinflammatory signaling in moderately affected AD hippocampal CA1.

The biological basis for the therapeutic mechanisms of depression is still unknown. We have previously performed expressed-sequence tag (EST) analysis to identify some molecular machinery responsible for antidepressant effect. Then, we developed our original cDNA microarray, on which cDNA fragments identified as antidepressant-related genes/ESTs were spotted. In this study, with this microarray followed by Western blot analysis, we have demonstrated the induction of vesicle-associated membrane protein 2(VAMP2/synaptobrevin-2) in rat frontal cortex not only after chronic antidepressant treatment, but also after repeated electroconvulsive treatment. On the other hand, expression of SNAP-25 and syntaxin-1 was not changed by these treatments. These components make a soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptor complex with VAMP2 and mediate the synaptic vesicle docking/fusion machinery. In conclusion, it is suggested that VAMP2/synaptobrevin-2 plays important roles in the antidepressant effects. Our results may contribute to a novel model for the therapeutic mechanism of depression and new molecular targets for the development of therapeutic agents.

This study examined whether comorbid symptoms influence the attentional biases associated with social anxiety and dysphoria using the Emotional Stroop Task (EST). Participants were recruited into three groups: a Social Anxiety group, a Dysphoric group, and a Social Anxiety/Dysphoric group. Four types of stimulus words were used: social anxiety threat, depressive threat, neutral words, and positive words. It was hypothesized that the Social Anxiety group would display an attentional bias to emotionally threatening stimuli whereas neither the dysphoric nor the Social Anxiety/Dysphoric group would display an attentional bias. Results found that the Social Anxiety group took longer to color name social threat and depressive words, whereas neither the Dysphoric nor the Comorbid group displayed an attentional bias. These results are discussed in light of their implications for cognitive theories of social anxiety and depression.

Using expressed sequence tag (EST) analysis, we previously identified certain molecular machinery that mediates antidepressant effects. To date, several partial cDNA fragments, termed antidepressant-related genes (ADRGs), have been isolated as ESTs from rat brain. In the present study, we identified two of the ADRGs to be rat neuroserpin. Using real-time quantitative PCR, we demonstrated increased neuroserpin mRNA expression in rat frontal cortex after chronic treatment with several classes of antidepressants, including imipramine, fluoxetine, sertraline, and venlafaxine. Electroconvulsive treatment (ECT), another therapeutic treatment for depression, also increased neuroserpin expression in rat frontal cortex. Neuroserpin is a serine protease inhibitor that is implicated in the regulation of synaptic plasticity, neuronal migration, and axogenesis in the central nervous system. In conclusion, our results support the hypothesis that neuroserpin-mediated plastic changes in frontal cortex may underlie the therapeutic action of antidepressants and ECT.

A 52 year old gentleman presented with chest pain, after a long distance flight from India; he had made long haul flights every 2 weeks over the last 5 years as part of his job. His ECG revealed T wave inversion in leads V1-3. Cardiac biomarkers including troponin were negative; we proceeded to exercise stress testing (EST). This revealed 2 mm ST depression at 2 min of the standard Bruce protocol, associated with chest pain. He was taken immediately to the coronary catheterization laboratory; engagement of the left main caused pressure damping with 6 French, then 5 French diagnostic Judkins left 4 catheters. An ostial left main stenosis was seen; the right and left coronary trees otherwise had no significant stenoses. He had normal LV function. He underwent inpatient CABG 7 days later.

Type-1 phosphatase (PP-1) was assessed in foot muscle (FM) and hepatopancreas (HP) of estivating (EST) Otala lactea. Snail PP-1 displayed several conserved traits, including sensitivity to inhibitors, substrate affinity, and reduction in size to a 39 kDa catalytic subunit (PP-1c). During EST, PP-1 activity in FM and HP crude extracts was reduced, though kinetics and protein levels of purified PP-1c isoforms were not altered. PP-1c protein levels increased and decreased in nuclear and glycogen-associated fractions, respectively, during EST. Gel filtration determined that a 257 kDa low K(m) PP-1alpha complex decreased during estivation whereas a 76 kDa high K(m) complex increased in EST. Western blotting confirmed that the 76 kDa protein consisted of PP-1alpha and nuclear inhibitor of PP-1 (NIPP-1). A suppression of PP-1 activity factors in the overall metabolic rate depression in estivating snails and the mechanism is mediated through altered cellular localization and interaction with binding partners.
