Abstract
INTRODUCTION Dopamine (DA) is likely to be involved in some depressive dimensions, such as anhedonia and amotivation, which account for a part of treatment-resistant forms. Monoamine oxidase inhibitors (MAOI) and direct D2 and D3 receptors agonists (D2/3r-dAG) are known to help, but we lack safety data about their combined usage. We report on safety and tolerance of the MAOI+D2r-dAG combination in a clinical series. METHOD All patients referred to our recourse center for depression between 2013 and 2021 were screened to select those who did receive the combo. Data were extracted from clinical files. RESULTS Sixteen patients of 60±17 years of age (8 women, 7 with age>65years, all suffered from treatment resistant depression, 7 with bipolar disorder) received the combo. There were no life-threatening adverse effects (AE). However, AE were reported by 14 patients (88%) most of which were mild and consisted of insomnia, nausea, nervousness, confusion, impulse control disorder and/or "sleep attacks". One patient presented a serious AE requiring a short hospitalization for confusion. Intolerance led to failure to introduce treatment in two patients (13%). The retrospective non-interventional design, the variety of molecules, and the modest sample size limited the scope of these results. CONCLUSION There was no life-threatening safety issue in combining MAOI and D2/3r-dAG, especially regarding cardiovascular side effects. The systematic screening of AE might account for their frequency, but these precluded the treatment in only two patients. Comparative studies are needed to assess the efficacy of this new combination.

Abstract
Searches for the lepton number violating K^{+}→π^{-}μ^{+}e^{+} decay and the lepton flavor violating K^{+}→π^{+}μ^{-}e^{+} and π^{0}→μ^{-}e^{+} decays are reported using data collected by the NA62 experiment at CERN in 2017-2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level: B(K^{+}→π^{-}μ^{+}e^{+})<4.2×10^{-11}, B(K^{+}→π^{+}μ^{-}e^{+})<6.6×10^{-11} and B(π^{0}→μ^{-}e^{+})<3.2×10^{-10}. These results improve by 1 order of magnitude over previous results for these decay modes.

Abstract
Background:Risperidone (RISP) may induce both elevated prolactin (PRL) levels and weight gain. the aim of this study was to evaluate body weight and mass index (BMI), and PRL modifications in schizophrenic patients treated for 1 year with long-acting risperidone (LAR).Methods:Body weight and BMI (calculated as weight in kilograms divide by height in meter squared) were determined at baseline and at endpoint in 19 schizophrenic patients (9 men and 10 women; mean[SEM] age 33.4[2.9] years). PRL levels were determined at baseline, after oral risperidone treatment (mean length of treatment: 79[30] days; mean dose: 5.8[0.5] mg daily) and during a 12 month treatment with LAR (mean dose: 50[10] mg every 2 weeks; PRL levels were measured before each injection).Results:At endpoint, a significant weight gain (Δweight: 8,1[1,4] kg) and BMI (ΔBMI: 2,9[0,5] kg/m²) was observed (both p< 0.0002). Compared with baseline, PRL levels were significantly increased (p< 0.0007; mean ΔPRL: 33[8] ng/ml). There was an association between ΔBMI>1,5 kg/m² and ΔPRL>40 ng/ ml (p< 0.04). Moreover ΔBMI was linked to the length of treatment (rho=0.47; n=19; p< 0.05).Conclusions:Our results suggest a link between weight gain and long term hyperprolactinemia in patients treated with LAR. It has been hypothesized that PRL may have a role in the regulation of food intake by increasing leptin synthesis and secretion.

Abstract
In this paper we present new results on upper limits for the search of Heavy Neutral Leptons (HNL) with data collected by NA48/2 (2003-2004), NA62-RK (2007) and NA62 (2015) CERN experiments. The data collected with different trigger configuration allow to search for both long and short living heavy neutrinos in the mass range below the kaon mass. In addition the status of the search for K+ → π+vv with the NA62 detector will be briefly presented.

Abstract
Les symptômes anhédoniques décrits dans la schizophrénie et dans la dépression pourraient être de nature différente [1]. Cette hypothèse a été explorée avec l’échelle EETP, différenciant l’anhédonie consommatoire (liée à l’éprouvé du plaisir) et l’anhédonie d’anticipation (liée à la motivation à rechercher le plaisir). Les patients souffrant de schizophrénie auraient un score plus bas à la composante anticipatoire [2]. Cette étude vise à évaluer les caractéristiques de l’anhédonie chez des patients dépressifs non psychotiques.MéthodeVingt-huit patients hospitalisés pour un épisode dépressif unipolaire ou bipolaire ont été inclus, (23 femmes, 5 hommes) âgés de 32 à 61 ans. Ils ont été évalués à l’aide de la MADRS et de l’EETP. Les corrélations entre les scores à la MADRS et ceux du plaisir anticipatoire et du plaisir consommatoire ont été analysées avec le test non paramétrique de Spearman.RésultatsLe score MADRS est inversement corrélé avec le score du plaisir consommatoire chez les patients avec un trouble dépressif unipolaire alors qu’il inversement corrélé avec le score du plaisir anticipatoire chez les patients bipolaires.ConclusionDans les dépressions bipolaires, l’anhédonie a une forme différente de celle rencontrée dans la dépression unipolaire. Cela pourrait signifier que la dépression bipolaire est plus en rapport avec un déficit motivationnel comme dans la schizophrénie. Cette étude montre aussi l’intérêt d’une utilisation plus systématique de l’échelle EETP dans les troubles thymiques. Cela pourrait aider à orienter l’action thérapeutique sur les mécanismes de l’éprouvé du plaisir ou sur ceux de la motivation.

Abstract
We demonstrate that abundant quantities of short-lived beta unstable ions can be trapped in a novel transparent Paul trap and that their decay products can directly be detected in coincidence. Low energy 6He+ (807 ms half-life) ions were extracted from the SPIRAL source at GANIL, then decelerated, cooled, and bunched by means of the buffer gas cooling technique. More than 10(8) ions have been stored over a measuring period of six days, and about 10(5) decay coincidences between the beta particles and the 6Li++ recoiling ions have been recorded. The technique can be extended to other short-lived species, opening new possibilities for trap assisted decay experiments.

Abstract
This study was aimed at investigating the relationships between sleep EEG abnormalities and hypothalamo pituitary adrenal (HPA) and hypothalamo pituitary thyroid (HPT) disturbances in major depressive disorder. Post dexamethasone (DXM) cortisol levels and the dual TSH response to 08:00 h and 23:00 h TRH administration were determined after a 2 weeks wash-out period in a group of 113 DSM-IV major depressed patients (72 females aged 44.3+/-13.0 and 41 males aged 45.7+/-11) who were consecutively admitted to undergo sleep EEG recordings. Post-DXM cortisolemia, 08:00 and 23:00 post-TRH TSH values, time spent in rapid eye movement sleep (REMS), in slow wave sleep (SWS), and in stage 2 as well as time awake after sleep onset were introduced in a principal component (PC) analysis. The four 3 PC scores explaining up to 74% of the data set were further calculated for each patients and used in a cluster analysis. A three-cluster solution was retained. Controlling for the effects of age and gender, patients belonging to these three clusters could clearly be differentiated on the basis of their neuroendocrine responses and on their sleep EEG profiles. Compared to the two other clusters, cluster I (n=26) patients showed the most severe sleep continuity disturbances. Post-DXM cortisol escape and sleep architecture disturbances (consisting of a shortening of REMS latency and a decreased SWS) identified patients belonging to cluster II (n=39). Patients in cluster III (n=48) had the lowest TSH response to TRH and the less marked sleep EEG alteration. Clinical or demographic variables were unable to differentiate the three clusters. Our results suggest that different biological dysfunctions could each underlie particular neuroendocrine and sleep EEG disturbances in major depression.

Abstract
There is evidence for inhibitory effects of adrenocorticosteroids on serotonergic (5-HT) activity. However, in depression the relationship between altered cortisol levels and brain 5-HT function remains to be clarified. The aim of this study was to investigate whether hypothalamic-pituitary-adrenal (HPA) axis hyperactivity is associated with 5-HT dysfunction in depressed patients, especially in those with suicidal behaviour. Cortisol levels following the dexamethasone suppression test (DST, 1 mg PO) and prolactin, corticotropin and cortisol responses to the d-fenfluramine test (d-FEN, 45 mg PO) - a specific 5-HT releaser/uptake inhibitor - were measured in 71 drug-free DSM-IV major depressed inpatients (40 with a history of suicide attempt, 31 without) and 34 hospitalized healthy control subjects. Depressed patients showed higher post-DST cortisol levels but similar responses to d-FEN compared with control subjects. Hormonal responses to d-FEN were not correlated with cortisol levels (basal or post-DST). Among the depressed patients, DST suppressors and DST nonsuppressors exhibited no significant difference in endocrine responses to d-FEN. However, patients with a history of suicide attempt, when compared with patients without such a history, showed lower hormonal responses to d-FEN but comparable basal and post-DST cortisol levels. Taken together these results suggest that, in depression, HPA axis hyperactivity is not responsible for the reduced 5-HT activity found in patients with a history of suicidal behavior.

Abstract
1. The aim of this study was to investigate hypothalamo-pituitary-thyroid axis (HPTA) functioning and sleep EEG disturbances in major depressive disorder. 2. Thyroid function was evaluated by determination of TSH levels before and after 8 AM and 11 PM TRH administration on the same day in a sample of 113 consecutively-admitted DSM-IV major depressed inpatients (72 females aged 44.3 +/- 13.0 and 41 males aged 45.7 +/- 10.7) that underwent sleep EEG recordings. 3. A blunted TSH response occurred in 15.9% for 8 AM deltaTSH (maximum increment above baseline at the 8 AM TRH challenge), in 39.8% for 11 PM deltaTSH and in 77% for deltadeltaTSH (difference between 11 PM deltaTSH and 8 AM deltaTSH). A negative correlation between deltadeltaTSH and duration of awakenings after sleep onset, and a shorter sleep onset latency in patients with a blunted 11 PM deltaTSH were found, but these two significant relationships disappeared after controlling for the effects of gender and age. 4. The present findings do not support the hypothesis that, in major depression, HPTA dysfunctioning, as reflected in TSH response to TRH, may be related to sleep EEG disturbances.

Abstract
The purpose of this study was to investigate differences in outcome following treatment with two different antidepressants in depressed patients according to their pretreatment hormonal response to clonidine. In all, 62 drug-free DSM-IV recurrent major depressed patients and 20 normal controls were studied. Patients were subsequently treated for 4 weeks with fluoxetine (n=28), or amitriptyline (n=34), and were then classified as responders or nonresponders according to their final Hamilton depression scale score. Compared to controls, depressed patients showed lower GH response to CLO (DeltaGH) (P<0.0002). One control (5%) and 35 depressed patients (56%) had blunted DeltaGH values. The efficacy of the two antidepressants was not significantly different: 15 patients responded to AMI (44%), seven patients responded to FLUOX (25%) (P>0.15). However, in the subgroup of patients with blunted DeltaGH levels, the rate of responders was higher for AMI (11/21) compared to FLUOX (1/14) treated patients (P<0.01). These results suggest that in depressed patients a blunted GH response to CLO could predict antidepressant response.

Abstract
The neuroendocrine responses to the alpha(2)-adrenoreceptor agonist clonidine (CLO) (0.35 mg if body weight <65 kg or 0.375 mg if body weight> or =65 kg, PO) were studied in a large group of subjects: 134 drug-free inpatients--with either DSM-IV schizophrenia (SCZ, n=31), schizoaffective disorder (SAD, n=16), or major depressive episode (MDE, n=87) - and 22 hospitalized controls (HCs). Comparison with a previous placebo test performed in a subgroup of 92 subjects (46 MDEs, 20 SCZs, 8 SADs, and 18 HCs) showed that CLO induced a significant increase of growth hormone, prolactin (PRL) and thyrotropin (TSH) levels but no significant change in adrenocorticotropin and cortisol release. According to diagnostic categories, we found significantly lower GH stimulation in MDEs and in SADs compared to HCs or to SCZs. In addition, we found significantly lower CLO induced PRL and TSH stimulations in paranoid SCZ patients compared to controls and disorganized SCZ patients. Taken together, these results suggest a hyposensitivity of noradrenergic alpha(2)-receptors in patients with affective symptoms.

Abstract
The present study was conducted in order to investigate the relationships between central noradrenergic (NA) and serotonergic (5-HT) function and clinical characteristics of a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. We measured growth hormone response (ΔGH) to clonidine (CLO) (an α2 NA agonist), as an index of central NA function, and prolactin response (APRL) to d-fenfluramine (d-FEN) (a specific 5-HT releaser/uptake inhibitor), as an index of central 5-HT function, in 53 medication-free depressed inpatients. On the basis of their CLO and d-FEN test responses, patients were classified into 4 groups. Group 1 (blunted ΔPRLd-FEN alone [11 %]) was characterized by a recent violent suicide attempt, a high degree of medical damage, and mild anxiety. Group 2 (blunted ΔGHCLO alone [32%]) was characterized by an absence of a history of suicide attempt and by severe anxiety. Group 3 (combination of blunted ΔGHCLO and APRLd-FEN [18%]) was characterized by a history of suicide attempts, total duration of the illness of over W years, age over 40 years, and more than 3 previous hospitalizations. Group 4 (no abnormality [39%]) had no specific clinical profile. These results suggest that, in depression, specific psychopathological features may be linked to 5-HT and/or NA dysfunction. However, our results also suggest that NA and/or 5-HT dysfunction are less likely to be the primary cause of mood disorders but are more indicative of failure of compensatory mechanisms involved in affective homeostatic processes.

Abstract
Previous studies of the prolactin response to D-fenfluramine in depressed patients have yielded inconsistent results. This may be because they did not address the question of suicidality. We carried out this study to test the hypothesis that lower prolactin response to D-fenfluramine is more closely associated with suicidal behavior than with depression itself. A D-fenfluramine test was performed in a sample of 18 healthy control subjects and in 85 drug-free inpatients with a DSM-III-R diagnosis of major depressive episode (49 with a history of suicide attempt, 36 without). Depressed inpatients with a history of suicide attempt showed a significantly lower prolactin response to D-fenfluramine compared to depressed inpatients without such a history and compared to control subjects. Healthy control subjects and depressed inpatients without a history of suicide attempt showed comparable levels of prolactin after D-fenfluramine. Time elapsed since suicide attempt did not influence prolactin level (baseline or post-stimulation). Results show that in our depressed drug-free inpatient sample, prolactin response to D-fenfluramine seems to be a marker of suicidality, but not of depression itself. We suggest that it is a trait marker of suicidality.

Abstract
1. It has been hypothesized that psychotic symptoms in depression may be due to increased dopamine activity secondary to hypothalamic-pituitary-adrenal (HPA) axis overactivity. 2. To test this hypothesis, the authors examined the cortisol response to dexamethasone suppression test (DST, 1 mg orally) and multihormonal responses to apomorphine (APO, 0.75 mg s.c.)--a dopamine agonist--in 150 drug-free hospitalized patients with DSM-IV major depressive episode with psychotic features (MDEP, n=35), major depressive episode without psychotic features (MDE, n=74), or schizophrenia paranoid type (SCZ, n=41), and 27 hospitalized healthy controls (HCs). 3. MDEPs showed increased activity of the HPA system (i.e. higher post-DST cortisol levels) than HCs, SCZs and MDEs. However, there were no differences in adrenocorticotropic hormone (ACTH), cortisol, prolactin and growth hormone (GH) responses to APO between MDEPs and MDEs and HCs. On the other hand, SCZs showed lower APO-induced ACTH stimulation and a higher rate of blunted GH than HCs, MDEs and MDEPs, suggesting a functional alteration of the hypothalamic dopamine receptors in SCZs. 4. In the total sample and in each diagnostic group, DST suppressors and non-suppressors showed no differences in hormonal responses to APO. 5. These results suggest a lack of causal link between HPA axis hyperactivity and dopamine dysregulation. In contrast to schizophrenia, psychotic symptoms in depression seem not to be related to dopamine function dysregulation.

Abstract
Recent studies in depression have reported alterations in both hypothalamic-pituitary-thyroid (HPT) axis activity and serotonin (5-HT) function; however, the functional relationships between the two systems have not been well defined in patients with major depressive episode. Thyrotropin (TSH) response to 0800 and 2300 h protirelin (TRH) challenges, and adrenocorticotropic hormone (ACTH), cortisol, and prolactin (PRL) responses to D-fenfluramine (D-FEN), a specific 5-HT releasing/uptake-inhibiting agent, were examined in 60 drug-free DSM-IV major depressed inpatients and 20 hospitalized controls. Compared with controls, patients showed lower basal serum 2300 h TSH, 2300 h maximum increment in serum TSH above baseline (delta TSH) and difference between 2300 h delta TSH and 0800 h delta TSH (delta delta TSH) levels. The hormonal responses to D-FEN (i.e. delta ACTH, delta cortisol and delta PRL) were interrelated. No significant difference in basal and post-D-FEN ACTH, cortisol or PRL values were found between controls and patients. A negative relationship between hormonal responses to D-FEN and 2300 h delta TSH and delta delta TSH values was observed in the depressed group. When patients were classified on the basis of their delta TSH test status, patients with reduced delta delta TSH values (i.e. with HPT axis abnormality) had hormonal D-FEN responses comparable to those of controls. Patients with normal delta delta TSH values (i.e. without HPT axis abnormality) showed lower ACTH, cortisol and PRL responses to D-FEN than controls and patients with abnormal delta delta TSH values. These results suggest that: (1) pathophysiological mechanisms other than 5-HT dysregulation may be involved in TSH blunting in major depressed patients; (2) 5-HT function is reduced in some depressed patients, especially those without HPT axis abnormality; and (3) HPT dysregulation may be regarded as a compensatory mechanism for diminished central 5-HT activity.

Abstract
We have genotyped unrelated French Alsatian schizophrenic and bipolar I disorder (BPD) patients and matched controls for the polymorphic CAG repeats within the genes for spinocerebellar ataxia type 1 (SCA1) and dentatorubral-pallidoluysian atrophy (B37), in order to test their possible involvement in these disorders. No alleles with abnormally expanded repeats were found in either gene in patients and controls. Differences in allele and genotype frequencies for the SCA1 CAG repeat between patients and controls were not significant, thus providing no support for its role as a possible positional candidate gene for schizophrenia and BPD in our patients. Chi square testing revealed a significant result (P = 0.019) for an association between the B37 CAG repeat on chromosome 12p and schizophrenia. This result was more significant when only schizophrenics with a positive family history were compared with controls (P = 0.0001). The frequencies of alleles with 14, 12, and 15 CAG repeats differed the most, respectively, between schizophrenics and controls. When choosing the median of the B37 allele distribution (15 CAG repeats) as a threshold, there were significantly more controls than schizophrenics in the group with longer alleles (15 or more repeats) and more schizophrenics with shorter alleles (P = 0.002 by Fisher exact test). No particular genotype was associated with schizophrenia. This result possibly indicates linkage disequilibrium with another locus on chromosome 12p and therefore deserves further attention. No association was found between the B37 CAG repeat and patients with BPD.

Abstract
Abnormality of the hypothalamic-pituitary-adrenal (HPA) axis has been one of the most consistently demonstrated biological markers of depressive disorder. It has also been proposed that abnormality of monoamine function plays a role in the pathogenesis of the disorder. In order to examine the interrelationships of the HPA axis with the dopaminergic, noradrenergic, and serotoninergic systems, we studied, in 52 medication-free inpatients with DSM-IV nonpsychotic major depressive disorder, the relationship between dexamethasone suppression test (DST) status and a series of multihormonal responses to apomorphine (APO), clonidine (CLO), and D-fenfluramine (FEN) tests. DST nonsuppressors did not present any difference compared with suppressors in growth hormone (GH) and cortisol stimulation by APO suggesting that a chronic elevation of cortisol did not lead to an alteration of dopaminergic activity in this population of nonpsychotic depressed inpatients. Cortisol and prolactin responses to FEN were comparable in nonsuppressors and in suppressors. In contrast, GH response to CLO was lower in DST nonsuppressors than in suppressors (p < .03), suggesting that the HPA abnormality indicated by a positive DST may be related to alpha 2-adrenoreceptor dysfunction.

Abstract
BACKGROUND This study sought to determine whether changes in thyroid function that may occur during antidepressant treatment are related to a direct effect of the drug on the thyroid axis or to a change in clinical state. METHODS Morning and evening thyroid function was evaluated in 30 euthyroid inpatients who met DSM-IV criteria for major depressive episode, by determination of free triiodothyronine, free thyroxine, and thyrotropin levels before and after 8 AM and 11 PM protirelin challenges (200 micrograms intravenously), on the same day. Results at baseline were compared with those after 1 month of antidepressant treatment with either amitriptyline hydrochloride, fluoxetine hydrochloride, or toloxatone. RESULTS Clinical efficacy and effects on thyroid function did not differ across the 3 antidepressant drugs. Compared with pretreatment values, significant reductions in basal serum 8 AM free thyroxine, 11 PM free thyroxine, and 8 AM free triiodothyronine levels and increases in 11 PM maximum increment in plasma thyrotropin level and the difference between 11 PM and 8 AM maximum increment in plasma thyrotropin values were observed in responders (n = 11) but not in partial responders (n = 6) or nonresponders (n = 13). Moreover, nonresponders exhibited lower pretreatment 11 PM thyrotropin values (basal and maximal increment above basal) than responders. CONCLUSIONS The results suggest that (1) changes in thyroid function are related to clinical recovery rather than to a direct effect of the antidepressant drug and (2) patients with the lowest pretreatment evening thyrotropin secretion have the lowest rate of antidepressant response, and this may contribute to treatment resistance.

Abstract
An implantable computerized electrical stimulation system designed to induce bladder evacuation in animal models (dogs) after spinal cord transection has been realized and evaluated. This fully programmable system is based on a handheld device and generates a wide range of stimuli through multichannel implantable miniaturized stimulator. Using the new bladder stimulator and inducing reversible fatigue to the external sphincter via the pudendal nerve enables us to reduce the bladder outlet resistance, resulting in the proper emptying of the bladder during stimulation without the need for sacral nerve rhizotomies and the pudendal nerve neurectomies. Four chronically affected dogs were studied to determine the optimal stimulation parameters for inducing a sphincter fatigue that would reliably empty the bladder for the duration of the experiment. These parameters were: maximum amplitude of 1.5 mA +/- 0.5 SD, stimuli composed of a high frequency signal of 200 Hz +/- 50 SD modulated by a low frequency signal of 10 Hz +/- 5 SD, pulse width controlled by a duty-cycle of 20% +/- 10 SD, sacral nerve stimulation of 50 s +/- 25 SD and fatiguing duration of 20 s +/- 5 SD.

Abstract
The dexamethasone suppression test (DST) and the clonidine stimulation test (CST) were studied in 47 depressed patients. Issues addressed included (1) the usefulness of both tests as markers of major depression; (2) the relationship between the two tests and the pathophysiology underlying this relationship; and (3) the psychopathological correlates of both tests. The widely reported link between abnormal DST results and melancholic depression was confirmed. The DST and the CST showed extensive overlap, suggesting a relationship in major depression between the biological abnormalities indexed by each test (i.e., hypothalamic-pituitary-adrenal axis and noradrenergic system). Finally, the psychopathological correlates of various subgroups categorized on the basis of test responses (e.g., normal test results, blunted CST results, and both abnormal DST and CST results) confirmed significant differences between groups on two items of the Hamilton Rating Scale for Depression: psychic anxiety and somatic anxiety. The results suggest that particular patterns of neuroendocrine abnormalities may be associated with particular profiles of depressive symptomatology.

Abstract
DNA fragments from a genomic library were used to establish the partial structure of the human dopamine D3 receptor gene (DRD3). Its coding sequence contains 6 exons and stretches over 40,000 base pairs. The complete DRD3 transcript and three shorter variants, in which the second and/or third exon are deleted, were detected in similar proportions in brains from four controls and three psychiatric patients. The Msp I polymorphism was localized in the fifth intron of the gene, 40,000 base pairs downstream the Bal I polymorphism and a PCR-based method was developed for genotyping this polymorphism. The distribution of the Msp I and Bal I genotypes were not independent in 297 individuals (chi 2 = 10.5, df = 4, P = 0.03), but only a weak association was found between allele 1 of the Bal I polymorphism and allele 2 of the Msp I polymorphism (chi 2 = 3.99, df = 1, P = 0.04). The previously reported association between homozygosity at both alleles of the Bal I polymorphism and schizophrenia was presently maintained in an extended sample, comprising 119 DSM-III-R chronic schizophrenics and 85 controls (chi 2 = 5.3, df = 1, P = 0.02) and found more important in mal than in females. The presence of the Bal I allele 2 is associated with an early age at onset, particularly in males (df = 35, t value = 2.6, P = 0.014). In the same sample, allelic frequencies, genotype counts, and proportion of homozygotes for the Msp I polymorphism did not differ between schizophrenics and controls (chi 2 = 0.06, df = 1, P = 0.80, chi 2 = 0.22, df = 1, P = 0.90 and chi 2 = 0.16, df = 1, P = 0.69, respectively). The large distance of the Msp I polymorphism from the Bal I polymorphism and its localization in the 3' part of the gene may explain the discrepant results obtained with the two polymorphisms.

Abstract
Commercially available stimulators lack several features, including multiple channel capability and flexible stimulation parameters. These factors limit clinical application. A new computerized electrical stimulator system was developed by our team and evaluated for its efficacy in bladder evacuation in an animal model after spinal cord transection. The system can generate a wide range of stimulation characteristics and has the feature of being a programmable multichannel pacemaker. It has enabled us to induce a reversible fatigue to the external sphincter that results in proper bladder emptying on stimulation. Using this new bladder pacemaker, 8 dogs were studied. We applied the concept of fatiguing of the external sphincter via the pudendal nerve to avoid rhizotomy. We determined the optimal stimulation parameters that can reliably empty the dog's bladder for the duration of the experiment, which lasted for 8 months. The new computerized electrical stimulation system achieved the objective of reducing bladder outlet resistance without the need for sacral rhizotomy.

The neuroendocrine responses to subcutaneous (SC) administration of the dopamine (DA) agonist apomorphine (APO) hydrochloride (0.75 mg) were studied in a large group of subjects: 110 drug-free inpatients with either DSM-III-R schizophrenia (SCZ, n = 46), schizoaffective disorder (SAD, n = 14), or major depressive episode (MDE, n = 50), plus 18 hospitalized controls. Compared to a saline test, APO induced a significant increase of growth hormone (GH), adrenocorticotropin (ACTH), and cortisol (COR) release and a decrease in prolactin (PRL) secretion. No change in thyrotropin (TSH) levels was observed. In the total sample the extents of ACTH, COR and GH responses were correlated, but in the group of 88 subjects who exhibit a normal GH stimulation this correlation disappeared. This discrepancy suggests that APO-induced ACTH and COR stimulation may be mediated by pathways different from those mediating GH stimulation. According to diagnostical categories, we found significant lower ACTH and COR stimulation in the schizophrenic group and in patients with SAD, compared with that among controls or depressed patients. We found also a significant difference between subgroups of schizophrenic patients. These results agree with the hypothesis that different aspects of psychosis might involve different subtypes of DA-receptors with different localizations and sensitivities.

Abstract
The serum levels of thyroid hormones and thyrotropin (TSH) were evaluated before and after 8 PM and 11 PM thyrotropin-releasing hormone (TRH) challenges, on the same day, in 41 drug-free DSM-III-R euthyroid major depressed inpatients and 16 hospitalized controls. Depressed patients exhibited elevated circulating concentrations of thyroid hormones, which were associated with and may have contributed to the blunted TSH response to TRH. This was confirmed by: (a) higher basal levels (albeit not always statistically significant) of free triiodothyronine (FT3B) and free thyroxine (FT4B) at 8 AM and 11 PM in the depressed patient population compared with the controls; (b) lower basal levels of TSH in the depressed subjects (even though this was only statistically significant at the 11 PM sampling) compared with the controls; (c) blunted TSH response to TRH (delta TSH) in the depressed group (although this was only statistically significant at 11 PM) and blunted delta delta TSH values (differences between 11 PM-delta TSH and 8 AM-delta TSH).

Abstract
Fluconazole is a new antifungal drug which is now very often used for the treatment of yeasts infections: mucocutaneous candidosis, systemic candidosis and cryptococcosis. Some resistance seems to occur in clinical practice. It turns out now that it must be necessary to test the drug susceptibility in vitro of the yeast strains isolated from patients. Unfortunately, a current laboratory technique to test this agent doesn't exist. In this work a useful method for Minimal inhibitory concentration (MIC) evaluation in a commercial available broth medium, and a technique for testing fluconazole disks on an agar medium are studied. 150 strains of different yeasts species are tested. A regression curve is performed to correlate the two methods.

Abstract
A new urinary-tract stimulator that is intended to restore normal bladder function to patients who have spinal-cord injuries is described. The system is composed of two principal parts. The first, which is external, consists of a hand-held device based on an inductive-coupling technique. This controller incorporates all the circuitry necessary to transmit data transdermally. The second, a fully programmable implantable device, includes a complementary metal oxide semiconductor gate-array integrated circuit controlling eight monopolar (or four bipolar) stimulation channels. To protect the tissues and the device, three different biocompatible polymers encapsulate the implant. In the experimental phase, the authors investigated the effect of early electrical stimulation of the bladder during the spinal-shock phase in paraplegic dogs. In addition, using the stimulator, they localized the parameters of stimulation that give the best results in terms of effective bladder pressure and voiding a high volume of urine.

Abstract
We describe a computerized experimental system to investigate the effect of early electrical stimulation of the bladder during the spinal shock phase in paraplegic dogs. This system is composed of two main devices; an external part (or controller) based on a portable microcomputer, and a versatile implant (internal) based on a multichannel CMOS microstimulator. Using a new operative technique, this system enabled us to obtain many favorable results.

Abstract
The aim of this study was to evaluate the effect on the activity of the hypothalamic-pituitary dopaminergic system of two new atypical antipsychotic drugs: the ergoline derivative SDZ HDC-912, which is a dopamine (DA) D2 receptor partial agonist; and the quinolinone derivative OPC-4392, which acts as an agonist at presynaptic DA autoreceptors and as an antagonist at post-synaptic D2 receptors. The effects of both compounds were compared to the effects of the benzamide derivative amisulpride. Prolactin (PRL) and growth hormone (GH) levels before and after challenge with apomorphine (Apo), a dopaminergic agonist, were determined after at least 2 weeks washout and again after 1 month of treatment in DSM-III-R schizophrenic inpatients. SDZ HDC-912 significantly decreased Apo-induced PRL inhibition, and tended to decrease PRL secretion and Apo-induced GH stimulation. OPC-4392 induced a significant decrease in baseline PRL and in Apo-induced PRL suppression, and a non-significant decrease in Apo-induced GH stimulation. The neuroendocrine profiles of these two compounds agree with their dopaminergic properties; however, the decrease in PRL basal level differentiates the two drugs from neuroleptic agents.

Abstract
The period of spinal shock which frequently follows spinal cord injury is associated with bladder areflexia and urinary retention. We studied the effect of early bladder electric stimulation on detrusor activity during the spinal shock phase in the dog. The animals had a spinal cord section at T10 vertebra, and their bladder management was assigned to one of the three following groups: intermittent catheterization, indwelling catheterization, and electric bladder stimulation. The parameters for evaluating each treatment included: blood chemistry, and radiographic and urodynamic tests. The most important finding was the early return of detrusor activity in the group of animals treated by early electric stimulation of the bladder.

Abstract
The stimulation of the sacral nerves to induce voiding is often associated with simultaneous contraction of the striated sphincter rendering micturition difficult or impossible. Rhizotomy of some sacral nerves was found to be necessary to facilitate voiding with stimulation. An main objective in the present experiment was to evaluate the feasibility of achieving the same result using electrical stimulation to fatigue the sphincter. In order to compare the effect of rhizotomy and fatiguing striated sphincter, the bladder outlet resistance was measured. S2 nerves were stimulated with 3 V, 35 Hz and 100 microseconds duration for 5 to 10 sec. Following S2 nerves stimulation the pudendal nerve was stimulated till we obtained sphincteric fatigue. The optimal parameter to induce sphincter fatigue were 3 V, 100-500 Hz and 100 microseconds. for 15-20 sec. The combined pressure-flow studies showed that fatiguing the sphincter via the pudendal nerve using these parameters was as good as cutting it in achieving bladder emptying with stimulation.

Abstract
In the present paper we describe a personal computer interface of a multichannel implantable urinary prosthesis. This system is composed of two main parts: the first one is internal and consists of an implant using a 4-microns CMOS gate array chip controlling a wide variety of waveforms via eight monopolar channels. The second, an external controller featuring a versatile software, a PCB card plugged in a portable microcomputer, and a radiofrequency-coupled technique. This device is used to transmit the power, the data and the synchronization clock to the implant by a simple binary signal modulating a 20 MHz carrier. We also report the features of implant encapsulation and electrode design and fabrication. In the experimental phase, we studied the effect of early electric stimulation of the bladder during the spinal shock phase in the dog. We present the operative techniques that enabled us to perform chronic electrostimulation of the sacral roots and discuss the results.

Abstract
Neural stimulation is potentially a valuable therapeutic tool in the treatment of neurogenic bladder with detrusor areflexia. We studied 20 dogs in different groups, up to eight months, and compared the effect of electric stimulation with intermittent catheterization, specially during spinal shock phase. We found that early stimulation hastened the return of detrusor activity. When stimulation was delayed, the bladder could still regain its activity, and when the pace-maker was turned off, the detrusor activity was gradually decreased. Neurostimulation can completely empty bladder up to eight months. The lowest A.Ch. content in detrusor muscle was found in intermittent catheterization group and in this group the detrusor strips showed marked supersensitivity to urecholine stimulation than the bladders managed by electric stimulation. Also, we found that electric stimulation reduced the complications caused by intermittent catheterization and protected kidney function.

Abstract
The latest classifications of mood disorders, such as DSM III and ICD 10, differ from previous ones by emphasizing the bipolar-unipolar distinction. This fairly recent distinction now enjoys a wide consensus. It is supported mainly by family studies. The first works originated from the school of Kleist and Leonhard and were quickly followed by reports by Perris and Angst (1966). Studies that followed the publication of DSM III confirm that the prevalence of bipolar mood disorders is twice as high among first-degree relatives of bipolar probands when compared with those of unipolar probands. Family studies suggest that unipolar and bipolar disorders are distinct but still share some degree of genetic overlap. Other genetic approaches such as twin and adoption studies are less conclusive. Recent linkage studies with genomic markers (RFLPs) cannot directly support the validity of the bipolar-unipolar distinction. They suggest the role of a major gene locus, notably in the Xq27-Xq28 region, only in a limited number of bipolar pedigrees. Most mood disorders might involve a polygenic environment; in this context, a more limited number of factors could be associated with the polarity of the disorder.

Abstract
A concerted study of the clinical and electrophysiologic effects of tianeptine was conducted in alcoholic patients hospitalized for 5 weeks for alcohol withdrawal cures and subsequent depression. Because of the well known manifestations of infraclinical cognition impairment, sleep disorders and greater susceptibility to undesirable effects of psychotropic drugs, which hinder health care in this type of patient, the authors investigated changes in cognitive functions and the effect of tianeptine on sleep organization and daytime vigilance. Results after 4 weeks treatment (3 times 12.5 mg/day) included: besides its antidepressant effect, tianeptine reduces the manifestations of anxiety, without sedation effects, either clinical or electrophysiologic; tianeptine has no deleterious effect on cognitive functions, on the contrary, it appears to favour recovery when they are impaired; tianeptine does not modify sleep structure, notably in paradoxal sleep; tianeptine is an antidepressant which has a good acceptability, even for a population at "risk".

Abstract
Controls (N = 45), schizophrenics (N = 20) and alcoholics (N = 23) were asked to choose at random a number between 1 and 10, 100 times. The correlation matrices of five different randomization indices were used to study within group variation; these matrices were similar for the normal and alcoholic groups, but very different for the schizophrenic group. The differences between the three groups were studied by canonical analysis and, in terms of the canonical variables, the mean performance of the normal group is clearly discriminated from that of the alcoholic and schizophrenic subjects.
