BACKGROUND Processed foods are major contributors to population dietary salt intake. Parts of the Australian food industry have started to decrease salt in a number of products. A definitive baseline assessment of current sodium concentrations in foods is key to targeting reformulation strategies and monitoring progress. OBJECTIVES Our objectives were to systematically collate data on the sod...
In order to determine the prevalence rate of Near-Death Experiences (NDEs) in south India, the author systematically surveyed four villages with a total population of 6430 persons. Eighteen persons were reported to have died (or nearly died) and revived. Thirteen (72%) of them reported having had NDEs which is about 2 cases per thousand of the population surveyed. Eleven features of the south I...
In traditional cancer diagnosis, pathologists examine biopsies to make diagnostic assessments largely based on cell morphology and tissue distribution. However, this is subjective and often leads to considerable variability. On the other hand, computational diagnostic tools enable objective judgments by making use of quantitative measures. This paper presents a systematic survey of the computat...
Mutations are the source of evolutionary variation. The interactions of multiple mutations can have important effects on fitness and evolutionary trajectories. We have recently described the distribution of fitness effects of all single mutations for a nine-amino-acid region of yeast Hsp90 (Hsp82) implicated in substrate binding. Here, we report and discuss the distribution of intragenic epista...
BACKGROUND Involving patients in health care is increasingly acknowledged as the best way to empower patients to manage their illness. Whilst the involvement of patients is laudable and widely recognised, how much they want to be involved needs to be ascertained. Research has shown that inappropriate provision of information to patients can increase their anxieties towards illness and alter per...
The production cross sections and the kinematical properties of primary residual nuclei have been studied in reactions 197Au + p, 208Pb + p,d, 238U + p,d, and 238U + 208Pb at energies around 1 A GeV. The measured kinematical properties of the residues were also used to disentangle the relevant reaction mechanisms, spallationevaporation and spallation-fission. The fragment separator FRS at GSI, ...
BACKGROUND Mini-proteins, defined as polypeptides containing no more than 100 amino acids, are ubiquitous in prokaryotes and eukaryotes. They play significant roles in various biological processes, and their regulatory functions gradually attract the attentions of scientists. However, the functions of the majority of mini-proteins are still largely unknown due to the constraints of experimental...
Time, effort and money involved in maintaining software has always been considered greater than its development time. Also, its vagueness in prediction at early stage of development makes the process more complex. Researchers and developers are working on devising various techniques/algorithms for better prediction. Present paper conducts a detailed survey on these techniques and identified sev...
Chaperonins are absolutely required for the folding of a subset of proteins in the cell. An earlier proteome-wide analysis of Escherichia coli chaperonin GroEL/GroES (GroE) interactors predicted obligate chaperonin substrates, which were termed Class III substrates. However, the requirement of chaperonins for in vivo folding has not been fully examined. Here, we comprehensively assessed the cha...
BACKGROUND Identification of MS registries and databases that are currently in use in Europe as well as a detailed knowledge of their content and structure is important in order to facilitate comprehensive analysis and comparison of data. METHODS National MS registries or databases were identified by literature search, from the results of the MS Barometer 2011 and by asking 33 national MS soc...
