An Enzymatic Cyclopentyl[b]indole Formation Involved in Scytonemin Biosynthesis

Previous studies of the biosynthetic enzymes involved in the assembly of scytonemin (1), a cyanobacterial sunscreen, have identified β-ketoacid 2 as an important intermediate that is produced by ThDP-dependent enzyme ScyA. We now report that ScyC, previously annotated as a hypothetical protein, catalyzes cyclization and decarboxylation of 2 to generate ketone 5. Assembly of the cyclopentyl[b]indole structure in this manner has little precedent in the chemical literature. Additional mechanistic experiments have revealed that cyclization likely precedes decarboxylation and that the latter event may provide a driving force for cyclopentane formation.Chemistry and Chemical Biolog

Stochastic domain decomposition for time dependent adaptive mesh generation

The efficient generation of meshes is an important component in the numerical solution of problems in physics and engineering. Of interest are situations where global mesh quality and a tight coupling to the solution of the physical partial differential equation (PDE) is important. We consider parabolic PDE mesh generation and present a method for the construction of adaptive meshes in two spatial dimensions using stochastic domain decomposition that is suitable for an implementation in a multi– or many–core environment. Methods for mesh generation on periodic domains are also provided. The mesh generator is coupled to a time dependent physical PDE and the system is evolved using an alternating solution procedure. The method uses the stochastic representation of the exact solution of a parabolic linear mesh generator to find the location of an adaptive mesh along the (artificial) subdomain interfaces. The deterministic evaluation of the mesh over each subdomain can then be obtained completely independently using the probabilistically computed solutions as boundary conditions. The parallel performance of this general stochastic domain decomposition approach has previously been shown. We demonstrate the approach numerically for the mesh generation context and compare the mesh obtained with the corresponding single domain mesh using a representative mesh quality measure

Validating a Definition of Relapse in Anorexia Nervosa

There is currently no consensus on the definition of “relapse” in anorexia nervosa (AN). This study sought to extend recent theoretical work exploring relapse in AN by comparing eighttheory-driven definitions of relapse constructs comprised of combinations of physical (i.e., weight status), cognitive (e.g., shape and weight concerns), and behavioral (e.g., bingeing and purging) symptoms, ranging from full-threshold DSM-5 AN to the presence of only disordered eating cognitions or only disordered eating behaviors in the absence of other symptoms. Among26 individuals with a lifetime history of AN who had reached recovery, five participants met criteria for relapse over the course of the study. We discuss patterns observed in these individuals compared to those who did not relapse. A small sample size limits the conclusions that can be drawn, though the authors encourage others to continue expanding upon this work with a larger sample size, ideally derived from multi-site studies.Master of Art

Adults’ Perceptions of Their Tinnitus and a Tinnitus Information Service

"Article Copyright 2010 The Authors." "Published edition Copyright 2010 Australian Academic Press. Published version of the paper reproduced here with permission from the publisher."The South Australian Government funds Tinnitus SA to provide advice and information to South Australians to assist in their understanding of tinni-tus and their decision making about tinnitus-related service provision. This qualitative study aimed to identify key motivations for adults seeking tinnitus advice, determine how those services are perceived, and provide insight into the help-seeking behaviour of those who experience tinni-tus. Participants in this study were recruited from Tinnitus SA’s attendance lists for their community information sessions held in 2008 and 2009. Of the 60 people contacted, 13 adults agreed to particpate in the semistructured interviews. Interviews, lasting approximately 45 minutes focused on interviewees’ perceptions of their tinnitus prior to attending the Tinnitus SA information session, their response to the information session itself, and their perceptions and actions following the information session. Grounded theory was used as the guiding method-ology for analysis of the transcribed interview data. The themes that emerged during analysis of the interviews fell into two broad descriptive categories: Empowerment through information and education; and If you can’t cure me I’ll cope. Together these categories led to the overarching theme of participants’ responses: ‘I don’t need help, but I’d like more information’. Further analy-sis revealed that the Tinnitus SA community sessions were the primary source of information for the majority of these participants and there was a high level of satisfaction with these sessions by contrast to other information sources
