Implementationhiv -AIDS Prevention and Tretment Program in South Sumatera, Indonesia

Human immunodeficiency virus (HIV) and Acquired Immune Deficiency Syndrome(AIDS) are worldwide public health issues. The spread of HIV-AIDS in high-risk groupshas been very rapid. This paper reports on a small-scale project which investigated attitudes to prevent ion and treatment programs for HIV-AIDS in Indonesia. This is important as there is a dearth of information about the number, type and spread of programs inthe region. Whilst it is known that programs have been implemented in various healthsectors HIV-AIDS rates continue to increase in this area. This is adescriptive study gatheringexploratory information about the number and nature of implementation of programs for theprevention and treatment of HIV-AIDS in the South Sumatra province. The data consists ofqualitative interviews with six key informants and secondary health data from these agencies.Results indicate that more cases were found between 2005 and 2011 in Palembang city, SouthSumatera.The increase of cases was supported by many health resources and services of HIV-AIDSprevention and treatment programs Furthermore, more HIV-AIDS cases are detected when theagencies are able to gain adequate funding and also have opportunities to engage incollaborativeworking practices. Barriers apparent in this study to reducing the spread of HIV-AIDS in thisarea appear to be related to lack of funding and limited prevention programs

The unsound object and intimate space

This research proposes the unsound object and intimate space as new approaches to listening to, writing about and performing creative sound works. The writing and the practical works sketch new territory around these two terms to pluralise sound art histories, with the aim of opening up practical discourse between artistic fields. The research begins with musique concrète and Pierre Schaeffer’s sound object, but draws on Mladen Dolar’s voice object, Christof Migone’s unsound and Six Years, Lucy Lippard’s account of conceptual art, instead of a strict acousmatic music narrative. A deliberate ‘wandering across borders’ is maintained throughout, to unpick the unsound object and intimate space through live work and ‘writing through’ of texts. My practice shifts between object based sound works, live art performance presentations, and open-ended text works. It tilts at intimate space by operating from the tabletop, from just beyond the page; my practice is made more uncertain and less fixed by its investigation of the unsound object. The project offers this as a positive outcome. In this project, I draw connections between the art object and the sound object, between mesostics and live art practice, between writing and space. These are tentatively offered as overlapping histories, as overlapping methods. Not as fixed Venn diagrams, or word clouds, but part of a flickering, oscillating unmethod that allows for both abstract and concrete, for waves and particles. The unmethod proposed in this project uses words like unshackling, unfixing, unpicking, and untethering to unsettle my practice and writing. The project suggests that destabilising existing definitions offers the potential of sound in silent media, and music beyond sound

Canine genome assembly correction facilitates identification of a MAP9 deletion as a potential age of onset modifier for RPGRIP1-associated canine retinal degeneration.

Retinal degeneration (RD) in the Miniature Long Haired Dachshund (MLHD) is a cone-rod dystrophy resulting in eventual blindness in affected individuals. In a previous study, a 44-nucleotide insertion (ins44) in exon 2 of RPGRIP1 was associated with RD. However, results on an extended population of MLHD revealed a variable RD onset age for ins44 homozygous dogs. Further investigations using a genome-wide association study comparing early onset and late onset RD cases identified an age of onset modifying locus for RD, approximately 30 Mb upstream of RPGRIP1 on chr15. In this investigation, target enriched sequencing identified a MAP9 deletion spanning approximately 22 kb associated with early RD onset. Identification of the deletion required correction to the CanFam3.1 genome build as canine MAP9 is part of a historic tandem duplication, resulting in incomplete assembly of this genome region. The deletion breakpoints were identified in MAP9 intron 10 and in a downstream partial MAP9 pseudogene. The fusion of these two genes, which we have called MAP9 EORD (microtubule-associated protein, early onset retinal degeneration), is in frame and is expressed at the RNA level, with the 3' region containing several predicted deleterious variants. We speculate that MAP9 associates with α-tubulin in the basal body of the cilium. RPGRIP1 is also known to locate to the cilium, where it is closely associated with RPGR. RPGRIP1 mutations also cause redistribution of α-tubulin away from the ciliary region in photoreceptors. Hence, a MAP9 partial deficit is a particularly attractive candidate to synergise with a partial RPGRIP1 deficit to cause a more serious disease.This is the author accepted manuscript.

TransRate: reference-free quality assessment of de novo transcriptome assemblies.

TransRate is a tool for reference-free quality assessment of de novo transcriptome assemblies. Using only the sequenced reads and the assembly as input, we show that multiple common artifacts of de novo transcriptome assembly can be readily detected. These include chimeras, structural errors, incomplete assembly, and base errors. TransRate evaluates these errors to produce a diagnostic quality score for each contig, and these contig scores are integrated to evaluate whole assemblies. Thus, TransRate can be used for de novo assembly filtering and optimization as well as comparison of assemblies generated using different methods from the same input reads. Applying the method to a data set of 155 published de novo transcriptome assemblies, we deconstruct the contribution that assembly method, read length, read quantity, and read quality make to the accuracy of de novo transcriptome assemblies and reveal that variance in the quality of the input data explains 43% of the variance in the quality of published de novo transcriptome assemblies. Because TransRate is reference-free, it is suitable for assessment of assemblies of all types of RNA, including assemblies of long noncoding RNA, rRNA, mRNA, and mixed RNA samples

Detection and molecular characterization of infectious bronchitis virus isolated from recent outbreaks in broiler flocks in Thailand

Thirteen field isolates of infectious bronchitis virus (IBV) were isolated from broiler flocks in Thailand between January and June 2008. The 878-bp of the S1 gene covering a hypervariable region was amplified and sequenced. Phylogenetic analysis based on that region revealed that these viruses were separated into two groups (I and II). IBV isolates in group I were not related to other IBV strains published in the GenBank database. Group 1 nucleotide sequence identities were less than 85% and amino acid sequence identities less than 84% in common with IBVs published in the GenBank database. This group likely represents the strains indigenous to Thailand. The isolates in group II showed a close relationship with Chinese IBVs. They had nucleotide sequence identities of 97-98% and amino acid sequence identities 96-98% in common with Chinese IBVs (strain A2, SH and QXIBV). This finding indicated that the recent Thai IBVs evolved separately and at least two groups of viruses are circulating in Thailand

The Replicase Gene of Avian Coronavirus Infectious Bronchitis Virus Is a Determinant of Pathogenicity

We have previously demonstrated that the replacement of the S gene from an avirulent strain (Beaudette) of infectious bronchitis virus (IBV) with an S gene from a virulent strain (M41) resulted in a recombinant virus (BeauR-M41(S)) with the in vitro cell tropism of the virulent virus but that was still avirulent. In order to investigate whether any of the other structural or accessory genes played a role in pathogenicity we have now replaced these from the Beaudette strain with those from M41. The recombinant IBV was in effect a chimaeric virus with the replicase gene derived from Beaudette and the rest of the genome from M41. This demonstrated that it is possible to exchange a large region of the IBV genome, approximately 8.4 kb, using our transient dominant selection method. Recovery of a viable recombinant IBV also demonstrated that it is possible to interchange a complete replicase gene as we had in effect replaced the M41 replicase gene with the Beaudette derived gene. Analysis of the chimaeric virus showed that it was avirulent indicating that none of the structural or accessory genes derived from a virulent isolate of IBV were able to restore virulence and that therefore, the loss of virulence associated with the Beaudette strain resides in the replicase gene

A LINE-1 insertion situated in the promoter of IMPG2 is associated with autosomal recessive progressive retinal atrophy in Lhasa Apso dogs

Funder: Lhasa Apso Breed CouncilFunder: Kennel Club Charitable Trust UKAbstract: Background: Canine progressive retinal atrophies are a group of hereditary retinal degenerations in dogs characterised by depletion of photoreceptor cells in the retina, which ultimately leads to blindness. PRA in the Lhasa Apso (LA) dog has not previously been clinically characterised or described in the literature, but owners in the UK are advised to have their dog examined through the British Veterinary Association/ Kennel Club/ International Sheep Dog Society (BVA/KC/ISDS) eye scheme annually, and similar schemes that are in operation in other countries. After the exclusion of 25 previously reported canine retinal mutations in LA PRA-affected dogs, we sought to identify the genetic cause of PRA in this breed. Results: Analysis of whole-exome sequencing data of three PRA-affected LA and three LA without signs of PRA did not identify any exonic or splice site variants, suggesting the causal variant was non-exonic. We subsequently undertook a genome-wide association study (GWAS), which identified a 1.3 Mb disease-associated region on canine chromosome 33, followed by whole-genome sequencing analysis that revealed a long interspersed element-1 (LINE-1) insertion upstream of the IMPG2 gene. IMPG2 has previously been implicated in human retinal disease; however, until now no canine PRAs have been associated with this gene. The identification of this PRA-associated variant has enabled the development of a DNA test for this form of PRA in the breed, here termed PRA4 to distinguish it from other forms of PRA described in other breeds. This test has been used to determine the genotypes of over 900 LA dogs. A large cohort of genotyped dogs was used to estimate the allele frequency as between 0.07–0.1 in the UK LA population. Conclusions: Through the use of GWAS and subsequent sequencing of a PRA case, we have identified a LINE-1 insertion in the retinal candidate gene IMPG2 that is associated with a form of PRA in the LA dog. Validation of this variant in 447 dogs of 123 breeds determined it was private to LA dogs. We envisage that, over time, the developed DNA test will offer breeders the opportunity to avoid producing dogs affected with this form of PRA

Defining the ABC of gene essentiality in streptococci

Background Utilising next generation sequencing to interrogate saturated bacterial mutant libraries provides unprecedented information for the assignment of genome-wide gene essentiality. Exposure of saturated mutant libraries to specific conditions and subsequent sequencing can be exploited to uncover gene essentiality relevant to the condition. Here we present a barcoded transposon directed insertion-site sequencing (TraDIS) system to define an essential gene list for Streptococcus equi subsp. equi, the causative agent of strangles in horses, for the first time. The gene essentiality data for this group C Streptococcus was compared to that of group A and B streptococci. Results Six barcoded variants of pGh9:ISS1 were designed and used to generate mutant libraries containing between 33,000-66,000 unique mutants. TraDIS was performed on DNA extracted from each library and data were analysed separately and as a combined master pool. Gene essentiality determined that 19.5% of the S. equi genome was essential. Gene essentialities were compared to those of group A and group B streptococci, identifying concordances of 90.2% and 89.4%, respectively and an overall concordance of 83.7% between the three species. Conclusions The use of barcoded pGh9:ISS1 to generate mutant libraries provides a highly useful tool for the assignment of gene function in S. equi and other streptococci. The shared essential gene set of group A, B and C streptococci provides further evidence of the close genetic relationships between these important pathogenic bacteria. Therefore, the ABC of gene essentiality reported here provides a solid foundation towards reporting the functional genome of streptococci
