Evoked potential correlates of information processing in psychiatric patients
Authors: Levit Robert A. , Sutton Samuel , Zubin Joseph 
Published: July 2009

SynopsisVisual and auditory evoked potentials were recorded from the scalp under conditions of uncertainty versus certainty, correctness versus incorrectness of pretrial guess, and shift versus repetition of the sensory modality of the stimulus. Schizophrenic patients, psychotic depressive patients, and normal controls were matched for age, sex, race, and socioeconomic status and educational level. The two patient groups were matched for medication (chlorpromazine) dosage level. Under all conditions normals exhibited the largest N1-P3 evoked potential amplitudes, while depressives exhibited the next largest and schizophrenics the smallest. All three groups had larger Ni-Pa amplitudes in the uncertain condition than in the certain condition. However, the effect of uncertainty was greatest in the normal group and least in the schizophrenic group. There were no significant interactions between group membership and guessing correctly and incorrectly. On the other hand, there was a significant interaction between group membership and modality shift. Depressives and normals tended to have larger N1-P3 amplitudes in the crossmodal condition, while schizophrenics tended to have larger amplitudes in the ipsimodal condition.
Aircraft noise and psychiatric morbidity
Authors: Gattoni F. , Tarnopolsky A. 
Published: July 2009

SynopsisAn earlier investigation which showed that admission rates to a psychiatric hospital were higher from the higher noise zones close to Heathrow Airport than from relatively quieter areas was repeated. The present paper could not confirm those results, although a trend in agreement with the original findings was found. The scope of the relationship between levels of aircraft noise and types of psychiatric morbidity is discussed.
Socio-cultural factors in the development of anorexia nervosa
Authors: Garner David M. , Garfinkel Paul E. 
Published: July 2009

SYNOPSISA population of professional dance (N= 183) and modelling (N= 56) students, who by career choice must focus increased attention and control over their body shapes, was studied. Height and weight data were obtained on all subjects. In addition, a questionnaire that is useful in assessing the symptoms of anorexia nervosa, the Eating Attitudes Test (EAT), was administered. Results of these tests were compared with those of normal female university students (N= 59), patients with anorexia nervosa (N= 68), and music students (N= 35).Anorexia nervosa and excessive dieting concerns were overrepresented in the dance and modelling students. Twelve cases (6·5%) of primary anexoria nervosa were detected in the dance group. All but one case developed the disorder while studying dance. Within the dance group those from the most competitive environments had the greatest frequency of anorexia nervosa. These data suggest that both pressures to be slim and achievement expectations are risk factors in the development of anorexia nervosa. The influence of socio-cultural determinants are discussed within the context of anorexia nervosa as a multidetermined disorder.
Aircraft noise and mental health: I. Prevalence of individual symptoms
Authors: Tarnopolsky Alex , Watkins Gareth , Hand David J. 
Published: July 2009

SYNOPSISA domiciliary survey (sample size circa 6000) was conducted in areas of different aircraft exposure affected by London (Heathrow) Airport. Respondents were urban dwellers age 16+. Since no differences were found in the prevalence of manifest psychiatric disorders, the frequency of 27 individual acute and chronic symptoms was investigated. Many acute symptoms showed an increase with noise, and this was particularly evident for waking at night, irritability, depression, difficulty in getting to sleep, swollen ankles, burns/cuts/minor accidents, and skin troubles. Two chronic symptoms, tinnitus and ear problems, showed evidence of an increase with noise, while most chronic symptoms were more common in low noise conditions. Results are controlled for the effects of age, sex and other standard epidemiological variables. Irrespective of their association with noise, most symptoms, chronic and acute, were more frequent among those respondents who also reported high annoyance. Suggestions for the analysis of surveys of health effects by noise are put forward.
Women whose mothers died in childhood: an outcome study
Authors: Birtchnell John 
Published: July 2009

SYNOPSISThe incidence of psychiatric symptoms in a community sample of mother-bereaved women was not excessive. No differences emerged when a series of 160 female psychiatric patients whose mothers died before age 11 were compared with 80 female controls. Fifty bereaved women who had bad relationships with their mother replacements had specific clinical characteristics.
Measuring social relationships The Interview Schedule for Social Interaction
Authors: Henderson Scott , Duncan-Jones P. , Byrne D. G. , Scott Ruth 
Published: July 2009

SYNOPSISIt is generally recognized that social relationships occupy a central position in psychiatry. To examine the role of social relationships in the onset of minor psychiatric morbidity it is necessary to construct an instrument which will meet the need for a valid, reliable and comprehensive index of social relationships. Such an instrument has now been developed and used in a sample of the general population.The Interview Schedule for Social Interaction arose from a research need, and was constructed to assess the availability and perceived adequacy for any individual of a number of facets of social relationships. These consist both of persons and of the provisions obtained through them. Data from a general population sample suggest this instrument to be sufficiently valid and reliable, and also sensitive to predictable variations between sociodemographic groups, to justify its use in clinical and epidemiological studies, both in psychiatry and general medicine.
Who Collaborative Study: assessment of depressive disorders
Authors: Sartorius N. , Jablensky A. , Gulbinat W. , Ernberg G. 
Published: July 2009

SYNOPSISIn the context of an ongoing WHO research programme in depression, a total of 573 patients consulting psychiatrists in Canada, Iran, Japan and Switzerland were assessed with the WHO/SADD schedule which proved to be a simple and reliable instrument for standardized recording of clinical data. The results indicated that the ‘average’ depressive patients seeking care in culturally different settings have many clinical features in common. A screening instrument, developed in the same study, has been shown to be effective in selecting depressive patients among in- and out-patient populations.
Biological component of the NIMH Clinical Research Branch Collaborative Program on the psychobiology of depression: I. Background and theoretical considerations
Authors: Maas James W. , Koslow Stephen H. , Davis John M. , Katz Martin M. , Mendels Joseph , Robins Eli , Stokes Peter E. , Bowden Charles L. 
Published: July 2009

SYNOPSISThere are many reports which suggest that patients with affective illness (mania and/or depression) have abnormalities in the functioning of one or more neurobiological systems. At a conference convened by the Clinical Research Branch, Division of Extramural Research Programs, National Institute of Mental Health, these findings were reviewed and some of the factors impeding movement towards a more complete and integrated view of the functioning of neurobiological systems in patients with mania or depression were identified. As a result, a multi-research centre, collaborative approach to the study of the psychobiology of affective disorders was developed. In this collaborative programme, which has now been underway for several years, the focus has been upon: (a) the assessment of the functioning of several different types of biological systems in the same patient, both before and during treatment; (b) obtaining a reasonably large number of patients and comparison subjects; and (c) the use within and across centres of standardized diagnostic categories and behavioural rating methodologies. In this paper the history, background, and rationale for this collaborative effort are reviewed. Those biological systems chosen for study are noted, and issues such as reliability and validity of diagnoses, measurement of state variables, assessment of change with treatment, and logistical and coordinating problems are discussed.
Schizophrenia and religious affiliation in Northern Ireland
Authors: Murphy H. B. M. , Vega G. 
Published: July 2009

SYNOPSISFirst admissions for schizophrenia in Northern Ireland are significantly higher for the Roman Catholics than for the rest of the population, although not as high as in the Irish Republic. The excess of Catholic cases affects only the never-married, and derives much more from the rural west of the territory than from the industrial east. It does not appear to be accounted for by geographyper se, by the differential use of services, diagnostic bias, social class distribution, or mean age at marriage. There are indications that some conflict around sex and marriage and, more doubtfully, a sense of relative deprivation may be contributing factors.
How patients describe bulimia or binge eating
Authors: Abraham Suzanne F. , Beumont P. J. V. 
Published: July 2009

SYNOPSISThirty-two patients who complained of episodes of ravenous overeating which they felt unable to control (bulimia) were asked to describe their behaviour and symptoms. There was considerable variation both between and within individuals, but a number of factors were defined which appeared to be common to all with the complaint. It is difficult to set up strict criteria for the recognition of bulimia, and those that have recently been proposed are criticized in the light of our present findings.
Dopamine metabolism in depressions, psychoses, and Parkinson's disease: the problem of the specificity of biological variables in behaviour disorders
Authors: Van Praag H. M. , Korf J. , Lakke J. P. W. F. , Schut T. 
Published: July 2009

SynopsisThe probenecid technique was used in a study of the central dopamine DA metabolism in patients with depressions, psychotic disorders, and Parkinson's disease. The disturbances found were neither nosologically nor syndromally specific, but appeared to be symptom-specific. Decreased DA turnover was associated with hypomotility, and increased DA turnover with hypermotility. Decreased DA turnover was probably related aetiologically to the hypomotility: the symptoms subsided after replenishment of the DA deficiency. The relation between increased DA turnover and hypermotility is still under investigation. In view of the findings obtained, a plea is made for the development of a functional psychopathology, in which psychiatric syndromes are ‘dissected’ into their constituent psychological dysfunctions. This development is expected to stimulate human brain and behaviour research. It can be achieved only by intensive collaboration between psychiatrists and experimental psychologists.
Activity in chronic schizophrenic patients: comparison of pimozide with fluphenazine in a double blind trial
Authors: Sims A. C. P. , Burnside I. G. 
Published: July 2009

SynopsisA double-blind crossover trial was carried out comparing pimozide with fluphenazine. The effects of the drugs on the activity of 20 chronic inert male schizophrenic patients were measured using nursing observations, psychiatric rating, and an operant conditioning method. When activity was assessed in these different ways, no significant difference was found between the two drugs on any of the measures. It is concluded that pimozide does not effectively increase the activity in such patients. It is considered that the free operant conditioning method used was shown to be a useful measure for comparing therapy in chronic schizophrenic patients.
Effect of depression on the speed of recall of pleasant and unpleasant experiences
Authors: Lloyd G. G. , Lishman W. A. 
Published: July 2009

SynopsisAn experiment is described in which depressed patients were asked to recall pleasant or unpleasant experiences from their past life in response to a standard series of stimulus words. The ratio between the time for recall of pleasant and unpleasant experiences was found to fall progressively with increasing severity of depression or of ‘neuroticism’ and to be significantly related to each. Among patients who scored relatively low on depression or neuroticism pleasant memories were recalled more speedily than unpleasant; among those who scored high this relationship was reversed. Possible mechanisms to account for these findings are discussed.
Survey of alcoholism and excessive drinking in a suburb of Buenos Aires
Authors: Tarnopolsky A. , del Olmo G. , Levav (Lubchansky) I. 
Published: July 2009

SynopsisA cross-sectional household survey of drinking patterns, categorized as alcoholism, excessive drinking, moderate drinking, and abstinence, was conducted in a middle and lower-class section of Greater Buenos Aires. Alcoholism and excessive drinking were present almost exclusively among males, and were more prevalent among the lower levels of education, occupation, or residential area, and also among migrants. Prevalence rates for males, aged 15 +, were: alcoholics 4.4% ±2.1 and excessive drinkers 12.2% ± 3.4. Details of the methods, the implication of the findings, and comparisons with other surveys are reported and discussed.

Phylogeny of Trematomus (Notothenioidei: Nototheniidae) inferred from mitochondrial and nuclear gene sequences
Authors: Kuhn Kristen L. , Near Thomas J. 
Published: July 2009

AbstractThe biota of Antarctica is amazingly rich and highly endemic. The phylogenetics of notothenioid fishes has been extensively investigated through analyses of morphological characters, DNA sequences from mitochondrial genes, and single copy nuclear genes. These phylogenetic analyses have produced reasonably similar phylogenetic trees of notothenioids, however a number of phylogenetic questions remain. The nototheniid clade Trematomus is an example of a group where phylogenetic relationships remain unresolved. In this paper we revisit the phylogenetic relationships of Trematomus using both increased taxon sampling and an expanded dataset which includes DNA sequences from two mitochondrial genes (ND2 and 16S rRNA) and one single-copy nuclear gene (RPS7). The Bayesian phylogeny resulting from the analysis of the combined mitochondrial and nuclear gene datasets was well resolved and contained more interspecific nodes supported with significant Bayesian posteriors than either the mitochondrial or nuclear gene phylogenies alone. This demonstrates that the addition of nuclear gene sequence data to mitochondrial data can enhance phylogenetic resolution and increase node support. Additionally, the results of the combined mitochondrial and nuclear Bayesian analyses provide further support for the inclusion of species previously classified as Pagothenia and Cryothenia in Trematomus.

Investigation of archaeal and bacterial diversity in fermented seafood using barcoded pyrosequencing
Authors: Roh Seong Woon , Kim Kyoung-Ho , Nam Young-Do , Chang Ho-Won , Park Eun-Jin , Bae Jin-Woo 
Published: July 2009

Abstract
Little is known about the archaeal diversity of fermented seafood; most of the earlier studies of fermented food have focused on lactic acid bacteria (LAB) in the fermentation process. In this study, the archaeal and bacterial diversity in seven kinds of fermented seafood were culture-independently examined using barcoded pyrosequencing and PCR–denaturing gradient gel electrophoresis (DGGE) methods. The multiplex barcoded pyrosequencing was performed in a single run, with multiple samples tagged uniquely by multiplex identifiers, using different primers for Archaea or Bacteria. Because PCR–DGGE analysis is a conventional molecular ecological approach, this analysis was also performed on the same samples and the results were compared with the results of the barcoded pyrosequencing analysis. A total of 13 372 sequences were retrieved from 15 898 pyrosequencing reads and were analyzed to evaluate the diversity of the archaeal and bacterial populations in seafood. The most predominant types of archaea and bacteria identified in the samples included extremely halophilic archaea related to the family Halobacteriaceae; various uncultured mesophilic Crenarchaeota, including Crenarchaeota Group I.1 (CG I.1a and CG I.1b), Marine Benthic Group B (MBG-B), and Miscellaneous Crenarchaeotic Group (MCG); and LAB affiliated with genus Lactobacillus and Weissella. Interestingly, numerous uncultured mesophilic Crenarchaeota groups were as ubiquitous in the fermented seafood as in terrestrial and aquatic niches; the existence of these Crenarchaeota groups has not been reported in any fermented food. These results indicate that the archaeal populations in the fermented seafood analyzed are diverse and include the halophilic and mesophilic groups, and that barcoded pyrosequencing is a promising and cost-effective method for analyzing microbial diversity compared with conventional approaches.
First Report of Goss's Bacterial Wilt and Leaf Blight on Corn Caused by Clavibacter michiganensis subsp. nebraskensis in Indiana
Authors: Ruhl G. , Wise K. , Creswell T. , Leonberger A. , Speers C. 
Published: July 2009

In August of 2008, leaves of hybrid corn (Zea mays L.) and popcorn from Pulaski and Jasper counties in northwest Indiana were submitted to the Purdue Plant and Pest Diagnostic Lab with symptoms characteristic of a bacterial disease. Symptomatic leaves had large, tan-to-gray necrotic lesions with dark freckling present within the lesions. Shiny bacterial exudate was present on the surface of many of the lesions. Microscopic observation revealed no fungal structures within the lesions, and bacterial streaming was observed from the cut edge of symptomatic tissue under ×100 magnification with phase contrast. A commercially available ELISA test (Agdia Inc., Elkhart, IN) determined that samples were negative for Pantoea stewartii, the causal agent of Stewart's bacterial leaf blight and wilt. A bacterial suspension was prepared from symptomatic tissue and streaked onto King's B medium and subcultured on semiselective CNS medium (1,2). Axenic, peach-colored colonies present on the CNS medium tested gram positive with a KOH test. Analysis of fatty acid methyl esters (MIDI Inc, Newark, DE) indicated that the strain was very similar (0.611) to Clavibacter michiganensis. Amplification of the 500-bp 16S rRNA region of the bacterial gene and subsequent BLAST alignments of the resulting sequence indicated a 99% match for C. michiganensis subsp. nebraskensis (GenBank Accession Nos. AM410697 and U09763; D16S2 gene bacterial library, version 2.10; MIDI Inc,). Koch's postulates were used to confirm pathogenicity of the isolated bacteria on corn inbred B73. Eighteen plants were mechanically inoculated at growth stage V1 to V2 with a bacterial suspension of approximately 1 × 108 CFU/ml prepared from cultures grown on CNS for 10 days at 28°C (2). Inoculum was rubbed onto leaves dusted with Carborundum and 0.1 ml of the bacterial suspension was injected into stems with a hypodermic needle. Nine control plants were inoculated with sterile water. Plants were kept at greenhouse conditions (24°C) with supplemental 400W high-pressure sodium light. Within 5 to 8 days, leaves and stems of all 18 inoculated plants developed water-soaked, necrotic lesions. No symptoms were observed in control plants. Bacteria were reisolated from symptomatic plants on CNS medium as described above, and gram-positive colonies were obtained. Reisolated strains were identical to C. michiganensis subsp. nebraskensis by D16S2 DNA sequence analysis, confirming the causal agent of the disease. Disease incidence in affected fields ranged from 20 to 60% and significant yield loss was reported. This confirmation is of regulatory importance because of potential export restrictions of Indiana-grown seed corn and popcorn to select countries. To our knowledge, this is the first report of Goss's bacterial wilt and leaf blight on corn in Indiana. References: (1) D. C. Gross and A. K. Vidaver. Phytopathology 69:82, 1979. (2) L. M. Shepherd.

Overexpressing AtPAP15 Enhances Phosphorus Efficiency in Soybean
Authors: Wang Xiurong , Wang Yingxiang , Tian Jiang , Lim Boon Leong , Yan Xiaolong , Liao Hong 
Published: July 2009

Abstract
Low phosphorus (P) availability is a major constraint to crop growth and production, including soybean (Glycine max), on a global scale. However, 50% to 80% of the total P in agricultural soils exists as organic phosphate, which is unavailable to plants unless hydrolyzed to release inorganic phosphate. One strategy for improving crop P nutrition is the enhanced activity of acid phosphatases (APases) to obtain or remobilize inorganic phosphate from organic P sources. In this study, we overexpressed an Arabidopsis (Arabidopsis thaliana) purple APase gene (AtPAP15) containing a carrot (Daucus carota) extracellular targeting peptide in soybean hairy roots and found that the APase activity was increased by 1.5-fold in transgenic hairy roots. We subsequently transformed soybean plants with AtPAP15 and studied three homozygous overexpression lines of AtPAP15. The three transgenic lines exhibited significantly improved P efficiency with 117.8%, 56.5%, and 57.8% increases in plant dry weight, and 90.1%, 18.2%, and 62.6% increases in plant P content, respectively, as compared with wild-type plants grown on sand culture containing phytate as the sole P source. The transgenic soybean lines also exhibited a significant level of APase and phytase activity in leaves and root exudates, respectively. Furthermore, the transgenic lines exhibited improved yields when grown on acid soils, with 35.9%, 41.0%, and 59.0% increases in pod number per plant, and 46.0%, 48.3%, and 66.7% increases in seed number per plant. Taken together, to our knowledge, our study is the first report on the improvement of P efficiency in soybean through constitutive expression of a plant APase gene. These findings could have significant implications for improving crop yield on soils low in available P, which is a serious agricultural limitation worldwide.
