Delay and failure in treatment seeking after first onset of mental disorders in the World Health Organization's World Mental Health Survey Initiative

Data are presented on patterns of failure and delay in making initial treatment contact after first onset of a mental disorder in 15 countries in the World Health Organization (WHO)''s World Mental Health (WMH) Surveys. Representative face-to-face household surveys were conducted among 76,012 respondents aged 18 and older in Belgium, Colombia, France, Germany, Israel, Italy, Japan, Lebanon, Mexico, the Netherlands, New Zealand, Nigeria, People''s Republic of China (Beijing and Shanghai), Spain, and the United States. The WHO Composite International Diagnostic Interview (CIDI) was used to assess lifetime DSM-IV anxiety, mood, and substance use disorders. Ages of onset for individual disorders and ages of first treatment contact for each disorder were used to calculate the extent of failure and delay in initial help seeking. The proportion of lifetime cases making treatment contact in the year of disorder onset ranged from 0.8 to 36.4% for anxiety disorders, from 6.0 to 52.1% for mood disorders, and from 0.9 to 18.6% for substance use disorders. By 50 years, the proportion of lifetime cases making treatment contact ranged from 15.2 to 95.0% for anxiety disorders, from 7.9 to 98.6% for mood disorders, and from 19.8 to 86.1% for substance use disorders. Median delays among cases eventually making contact ranged from 3.0 to 30.0 years for anxiety disorders, from 1.0 to 14.0 years for mood disorders, and from 6.0 to 18.0 years for substance use disorders. Failure and delays in treatment seeking were generally greater in developing countries, older cohorts, men, and cases with earlier ages of onset. These results show that failure and delays in initial help seeking are pervasive problems worldwide. Interventions to ensure prompt initial treatment contacts are needed to reduce the global burdens and hazards of untreated mental disorders.     

韩国与中国东北地区松鼠线粒体DNA控制区的序列变异

为了研究松鼠东北亚种(Sciurus vulgaris manchuricusThomas)不同种群的序列变异水平并进一步确定分类地位,我们分析了韩国5个地点和中国东北2个地点的松鼠标本的线粒体DNA控制区的全序列(1 058 bp)。39个韩国松鼠标本显示出21种单倍型,这些单倍型间的平均Tamura-Nei距离为1·0%; 24个中国松鼠标本显示21种单倍型,单倍型间的平均Tamura-Nei距离为1·4% (1 058 bp的全序列中发生变异的位点有119个,占11·2%)。韩国松鼠和中国松鼠间的平均距离为1·3%。并且韩国和中国松鼠的所有42个单倍型形成了一个单系分支,Fst值为0·04,表明在两个国家的松鼠间没有发生遗传分化。因此,序列分析的分子生物学的结果支持现行的分类,即来自韩国的朝鲜亚种(S·v·coreae)是中国北部地区松鼠东北亚种(S·v·manchuricus)的同物异名。这还需要进一步对北朝鲜和中国东北其它地区更多标本的分子和形态学分析来验证这一结论。     

First record of the family Embolemidae (Hymenoptera: Chrysidoidea) from Korea

The family Embolemidae Westwood, 1833 is recorded for the first time in Korea, based on a species Embolemus ruddii Westwood. A diagnosis of this species complemented by digital images are provided.     

Characterization of polymorphic tetranucleotide microsatellite loci from the Siberian weasel (Mustela sibirica)

Nine tetrarepeat microsatellite loci for Siberian weasel (Mustela sibirica) were characterized. By using 35 individuals of unknown relationship collected from Taiwan, we evaluated the polymorphism of these loci. The number of alleles for each locus ranged from five to 12 (mean = 8.78 alleles) and the observed heterozygosity from 0.429 to 0.962 (mean = 0.688) and all loci conformed to Hardy–Weinberg expectation.     

Development of compound microsatellite markers in the harmful dinoflagellate Cochlodinium polykrikoides (Dinophyceae)

We isolated 15 polymorphic microsatellites from Cochlodinium polykrikoides. These loci provide a class of highly variable genetic markers, as the number of alleles ranged from two to 15, and the estimate of gene diversity was from 0.083 to 0.880 across the 15 microsatellites. We consider that these loci have a potential to reveal the genetic structure and gene flow among C. polykrikoides populations.     

Patterns of protein synthesis and accumulation during oogenesis in the polychaete,Pseudopotamilla occelata Moore

Summary

Proteins synthesized and accumulated during oogenesis or Pseudopotamilla occelata were analyzed by two-dimensional Polyacrylamide gel electrophoresis and fluorography. Significant changes in the patterns of synthesis and accumulation occur during oogenesis, paticularly between previtellogenic and vitellogenic stages, although many of the proteins are represented throughout the process. The changes may be generally dependent upon the variation in the gene expression affecting autosynthesis of proteins. However, appearance of proteins, which occur only at the vitellogenic stages but apparently not synthesized within the oocytes, indicates that heterosynthetic proteins are stage-specifically transported into oocytes.     

Eimeria ontarioensis n. sp., E. confusa Joseph, 1969 and Eimeria sp. (Protozoa: Eimeriidae) from the Ontario Gray Squirrel Sciurus carolinensis*

SYNOPSIS. Eimerians from 27 gray squirrels Sciurus carolinensis sampled in Waterloo County were studied. Two double-walled species, E. ontarioensis n. sp. which was piriform (36.8 × 23.5) and E. confusa Joseph which was subspherical (35.7 × 28.4), were described and compared with similar species from the genus Sciurus. Eimeria sp., ellipsoidal (24.9 × 14.4), from Ontario gray squirrels resembled E. ascotensis and E. neosciuri and was a new eimerian record from Ontario. The zoogeographic significance of E. ontarioensis n. sp. and E. sp. in North American gray squirrels is discussed.     

Spectrometric studies on stability of tenuazonic acid (TeA) solution in organic solvents

The stability of tenuazonic acid solution at different temperatures and storage times was studied using methanol, methanol-water (8:2 v/v), benzene and benzene-acetonitrile (98:2 v/v) as solvents. Solutions were analysed by a spectrometric method TeA U.V.-spectrum was recorded. Results indicated that the optimum temperature for long-time storage period of tenuazonic acid solution in any solvent assayed is -20°C. Benzene and benzene-acetonitrile (98:2 v/v) could be advised to make tenuazonic acid solution which will be stored less than 2 months at 4°C. Methanol and methanolwater (8:2 v/v) are not recommended because a low stability of TeA solution in this solvents.     

Black light trap collections in Wangging county and Yanji city,Jilin Province,China, August 2006–2007

Adult mosquito surveillance was conducted using black light traps in August of 2006 and 2007 at Wangging county and Yanji city, Jilin Province, China to identify the distribution of anopheline mosquitoes in northern China. A total of 2459 female mosquitoes comprising three genera and eight species including Anopheles (Anopheles) lesteri, An. (Ano.) kleini, An. (Ano.) pullus, Culex inatomii, Cx. orientalis, Cx. pipiens, Cx. bitaeniorhynchus and Aedes vexans nipponii were collected. The most commonly collected species was An. kleini which had not been previously reported from China. Anopheles sinensis sensu stricto is commonly collected throughout China, but was not collected from these areas.     

Systematics and phylogeography of the Taiwanese endemic minnow Candidia barbatus (Pisces: Cyprinidae) based on DNA sequence,allozymic, and morphological analyses

The phylogeographical patterns of the endemic minnow, Candidia barbatus, were examined using mitochondrial (mt) cytochrome b sequences, allozyme electrophoresis, and morphology. The 23 mtDNA haplotypes recovered were grouped into six lineages (A–F). According to a molecular clock of 1.7% per million years, we estimated that the colonization of C. barbatus to Taiwan took place three million years ago with several subsequent vicariance events. In the allozyme analysis, the Bayesian approach partitioned different populations into three clusters, with clusters I, II, and III mainly found in northern, central, and southern Taiwan, respectively. Morphologically, fish from north and south of the Tropic of Cancer had distinct numbers of lateral line scales and were separated into two morphs. The cohabitation of different mtDNA lineages with high allozymic and morphological similarities suggests that interbreeding amongst them is possible. Therefore, in spite of highly differentiated mtDNA, samples from different collecting sites should be considered a single species. Based on the current population distribution and levels of divergence, we propose that both orogenic activities and marine regression during glacial epoch were the two main forces shaping population differentiation of this species. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 161 , 613–632.
