This article describes the results of the WPA-WHO Global Survey of 4,887
psychiatrists in 44 countries regarding their use of diagnostic classification
systems in clinical practice, and the desirable characteristics of a classification
of mental disorders. The WHO will use these results to improve the clinical
utility of the ICD classification of mental disorders through the current
ICD-10 revision process. Participants indicated that the most important purposes
of a classification are to facilitate communication among clinicians and to
inform treatment and management. They overwhelmingly preferred a simpler system
with 100 or fewer categories, and over two-thirds preferred flexible guidance
to a strict criteria-based approach. Opinions were divided about how to incorporate
severity and functional status, while most respondents were receptive to a
system that incorporates a dimensional component. Significant minorities of
psychiatrists in Latin America and Asia reported problems with the cross-cultural
applicability of existing classifications. Overall, ratings of ease of use
and goodness of fit for specific ICD-10 categories were fairly high, but several
categories were described as having poor utility in clinical practice. This
represents an important focus for the ICD revision, as does ensuring that
the ICD-11 classification of mental disorders is acceptable to psychiatrists
throughout the world. 相似文献

The tumor suppressor, QM, has been cloned and characterized from various model organisms such as human, plant and invertebrates. Yet, it has not been seriously investigated for its role in conjunction with antiviral mechanisms involving innate insect immunity. From the expressed sequence tag (ESTs) project, conducted with larval cDNA library of cabbage butterfly, Pieris rapae, a partial fragment (718 bp) of QM homologue, termed PrQM containing 660 bp long open reading frame (ORF) encoding protein of 219 amino acids was identified. In silico analysis of PrQM ORF revealed the presence of ribosomal protein L10a/L10e type domain. Phylogenetic analysis of the P. rapae QM‐like protein showed high amino acid sequence similarity with other PrQM polypeptides identified from Heliothis virescenes (95%), Plutella rapae (92%), Bombyx mori (92%), Drosophila melanogaster (89%), and Polyrhachis vicina (85%). The butterfly QM has the closest phylogenetic relationship to a moth (Hv) QM homologue. Further investigations revealed the expression of PrQM at all developmental stages, with pronounced presence at the egg stage. In addition, spatial pattern analysis indicated its high expression in the head, salivary gland, integument and fat body with visible presence in Malpighian tubule and gut. Time course expression studies conducted after immune‐challenge with lipoteichoic acid (LTA) showed the induction of PrQM mRNA at 12 h and 24 h after challenge and also in response to granulovirus (GV). Results of this investigation therefore suggest possible role of QM‐like proteins from Pieris rapae to be involved in innate antiviral immune responses. Further elucidation on the precise function of PrQM during antiviral immune responses by using RNA interference remains a viable research front. 相似文献

During endocytosis, membrane components move to intraluminal vesicles of the endolysosomal compartment for digestion. At the late endosomes, cholesterol is sorted out mainly by two sterol-binding proteins, Niemann-Pick protein type C (NPC)1 and NPC2. To study the NPC2-mediated intervesicular cholesterol transfer, we developed a liposomal assay system. (Abdul-Hammed, M., B. Breiden, M. A. Adebayo, J. O. Babalola, G. Schwarzmann, and K. Sandhoff. 2010. Role of endosomal membrane lipids and NPC2 in cholesterol transfer and membrane fusion. J. Lipid Res. 51: 1747–1760.) Anionic lipids stimulate cholesterol transfer between liposomes while SM inhibits it, even in the presence of anionic bis(monoacylglycero)phosphate (BMP). Preincubation of vesicles containing SM with acid sphingomyelinase (ASM) (SM phosphodiesterase, EC 3.1.4.12) results in hydrolysis of SM to ceramide (Cer), which enhances cholesterol transfer. Besides SM, ASM also cleaves liposomal phosphatidylcholine. Anionic phospholipids derived from the plasma membrane (phosphatidylglycerol and phosphatidic acid) stimulate SM and phosphatidylcholine hydrolysis by ASM more effectively than BMP, which is generated during endocytosis. ASM-mediated hydrolysis of liposomal SM was also stimulated by incorporation of diacylglycerol (DAG), Cer, and free fatty acids into the liposomal membranes. Conversely, phosphatidylcholine hydrolysis was inhibited by incorporation of cholesterol, Cer, DAG, monoacylglycerol, and fatty acids. Our data suggest that SM degradation by ASM is required for physiological secretion of cholesterol from the late endosomal compartment, and is a key regulator of endolysosomal lipid digestion. 相似文献

Pathogen affects plant growth, host health and productivity. Endophytes, presumed to live inside the plant tissues, might be helpful in sustaining the future of agriculture. Although recent studies have proven that endophytes can be pathogenic, commensal, non-pathogenic, and/or beneficial, this review will focus on the beneficial category only. Beneficial endophytes produce a number of compounds which are useful for protecting plants from environmental conditions, enhancing plant growth and sustainability, while living conveniently inside the hosts. The population of endophytes is majorly controlled by location, and climatic conditions where the host plant grows. Often the most frequently isolated endophytes from the tissues of the plant are fungi, but sometimes greater numbers of bacteria are isolated. Beneficial endophytes stand a chance to replace the synthetic chemicals currently being used for plant growth promotion if carefully explored by researchers and embraced by policymakers. However, the roles of endophytes in plant growth improvement and their behavior in the host plant have not been fully understood. This review presents the current development of research into beneficial endophytes and their effect in improving plant growth. 相似文献

Insect c‐type lysozymes are antibacterial proteins that are synthesized in different organs with high activity against Gram‐positive bacteria. Because lysozymes possess muramidase activity, they also play an important role in the digestion of bacteria in Diptera. Triatomines express lysozyme‐encoding genes constitutively in the anterior region (cardia and stomach) of the midgut and the fat body after injection of bacteria into the haemocoel. The present study describes the overexpression of the Triatoma brasiliensis lysozyme 1 (lys1) in Escherichia coli. Recombinant T. brasiliensis Lys1 (TbLys1) is purified after solubilization of the inclusion bodies. The protein refolds successfully, showing muramidase activity against Micrococcus lysodeikticus lyophilized cells, after enterokinase cleavage of its thioredoxin fusion protein. In in‐gel zymograms and turbidimetric liquid assays TbLys1 is broadly active under alkaline and acid conditions, indicating a possible digestive function in the two physiologically different midgut regions of the bug: the stomach and small intestine. Muramidase activity is shown in the stomach and small intestine content of unfed bugs and bugs at different days after feeding, respectively. Western blot analysis identifies TbLys1 as lysozyme. 相似文献

The 14-3-3 proteins are known to play an important regulatory role in apoptosis, and various cell signaling cascades. However, no investigation on mosquito 14-3-3 has been reported. To investigate the role of 14-3-3 proteins in mosquito midgut cells undergoing apoptosis, we decided to take advantage of Anopheles gambiae genome data, and were able to find Ag14-3-3ζ cDNA and protein sequences from Ensembl ( http://www.ensembl.org ). Further in silico analysis using BLAST search revealed that Ag14-3-3ζ protein is a polypeptide of 248 amino acids, and shares high identity with 14-3-3ζ homologues from Aedes aegypti (100%), Drosophila melanogaster (96%) and Bombyx mori (93%). Due to the perfect match and high homology, we hypothesized that Ag14-3-3ζ peptide antibody may recognize 14-3-3ζ homologs from other anopheline mosquitoes and insects. We thus generated 14-3-3ζ polyclonal antibody against a unique region located in the C-terminal end of Ag14-3-3ζ after in silico epitope analysis. As expected, zoo-western blot analysis of 14-3-3 proteins revealed that a polyclonal antibody against Ag14-3-3ζ peptide recognizes 14-3-3 homologs from dipteran and lepidopteran insects. To our knowledge, this is the first report on polyclonal antibody production against mosquito 14-3-3ζ. The mosquito-based 14-3-3ζ antibody will be very useful for studying the functional characterization of 14-3-3ζ in the context of host–pathogen interactions in midgut and other immune cells. 相似文献

Rising atmospheric carbon dioxide (CO2) concentration is increasingly affecting food production but how plant diseases will influence production and quality of food under rising CO2 is not well understood. With increased plant biomass at high CO2 the stubble‐borne fungal pathogen Fusarium pseudograminearum causing crown rot (CR) of wheat may become more severe. We have studied inoculum production by Fusarium using fungal biomass per unit wheat stubble, stem browning from CR and the saprophytic fitness of Fusarium strains isolated from two wheat varieties grown in 2007 and 2008 at ambient and elevated CO2 in free‐air CO2 enrichment (FACE) with or without irrigation and once in a controlled environment. Fungal biomass, determined using primers for fungal ribosomal 18s and the TRI5 gene, increased significantly at elevated CO2 in two of the three studies. Stem browning increased significantly at elevated CO2 in the 2007 FACE study. At elevated CO2 increased stem browning was not influenced by irrigation in a susceptible variety but in a resistant variety stem browning increased by 68% without irrigation. Wheat variety was significant in regression models explaining stem browning and Fusarium biomass but pathogen biomass at the two CO2 levels was not significantly linked to stem browning. Fusarium isolates from ambient and elevated CO2 did not differ significantly in their saprophytic fitness measured by the rate of colonization of wheat straw. We show that under elevated CO2Fusarium inoculum in stubbles will be amplified from increased crop and pathogen biomass while unimpeded saprophytic fitness will retain its effectiveness. If resistant varieties cannot completely stop infection, Fusarium will rapidly colonize stubble to further increase inoculum once the crop is harvested. Research should move beyond documenting the influence of elevated CO2 to developing disease management strategies from improved knowledge of pathogen biology and host resistance under rising CO2. 相似文献
