Transcriptomic Analysis of Peritoneal Cells in a Mouse Model of Sepsis: Confirmatory and Novel Results in Early and Late Sepsis.
Background
The events leading to sepsis start with an invasive infection of a primary organ of the body followed by an overwhelming systemic response. Intra-abdominal infections are the second most common cause of sepsis. Peritoneal fluid is the primary site of infection in these cases. A microarray-based approach was used to study the temporal changes in cells from the peritoneal cavity of septic mice and to identify potential biomarkers and therapeutic targets for this subset of sepsis patients. Results
We conducted microarray analysis of the peritoneal cells of mice infected with a non-pathogenic strain of Escherichia coli. Differentially expressed genes were identified at two early (1 h, 2 h) and one late time point (18 h). A multiplexed bead array analysis was used to confirm protein expression for several cytokines which showed differential expression at different time points based on the microarray data. Gene Ontology based hypothesis testing identified a positive bias of differentially expressed genes associated with cellular development and cell death at 2 h and 18 h respectively. Most differentially expressed genes common to all 3 time points had an immune response related function, consistent with the observation that a few bacteria are still present at 18 h. Conclusions
Transcriptional regulators like PLAGL2, EBF1, TCF7, KLF10 and SBNO2, previously not described in sepsis, are differentially expressed at early and late time points. Expression pattern for key biomarkers in this study is similar to that reported in human sepsis, indicating the suitability of this model for future studies of sepsis, and the observed differences in gene expression suggest species differences or differences in the response of blood leukocytes and peritoneal leukocytes
Enrichment of antioxidant capacity and vitamin E in pita made from barley
This study aimed to enhance total antioxidant and vitamin E content of pita bread, by replacing 50% of the standard baker's flour with flours milled from covered (WI2585 and Harrington) or hulless (Finniss) barley genotypes, previously shown to have high antioxidant and vitamin E levels at harvest. Pita breads were made from either 100% baker's flour (control) or 50% malt flour, whole-grain flour, or flour from barley grains pearled at 10%, 15%, and 20% grain weight. Antioxidant capacity and vitamin E content of flours and pitas were determined by their ability to scavenge 2,2-diphenyl-1-picrylhydrazyl radicals and high performance liquid chromatography, respectively. The physical and sensory properties of the pitas were also assessed. All pitas made from either whole grain or pearled barley flour had a higher antioxidant capacity and most also had higher vitamin E content than standard pita. The antioxidant and vitamin E levels were reduced in pearled compared to whole grains, however the extent of that reduction varied among genotypes. The greatest antioxidant and vitamin E levels were found in pita made from malt flour or Finniss whole grain flour. Furthermore, sensory analysis suggested these pitas were acceptable to consumers and retained similar physical and sensory properties to those in the control pita.Thi Thu Dung Do, Beverly Muhlhausler, Amanda Box and Amanda J.

Towards a greater dialogue on disability between Muslims and Christians
Attitudes to disability and disabled people by Muslims – focusing on attitudes in the Middle East and North Africa - and Christians – focusing on the West (here taken to mean Europe, North America and Australasia) - were examined through a grounded theory literature search, with the study being divided into three phases of reading and analysis. The aims of study were to develop a dialogue on disability between the two cultures, to inform an understanding of the attitudes to disability in the two cultures, and to inform cultural practice in promoting support and equality in both cultures. The study finds that Islam and Christianity have much in common and are a force for good in promoting and developing disability equality in both Muslim and Christian cultures
Imaging of Flames in Cement Kilns To Study the Influence of Different Fuel Types
The
cement industry aims to use an increased amount of alternative
fuels to reduce production costs and CO<sub>2</sub> emissions. In
this study three cement plants firing different kinds and percentages
of alternative fuel were studied. A specially developed camera setup
was used to monitor the flames in the three cement kilns and assess
the effect of alternative fuels on the flame. It was found that cofiring
with solid recovered fuel (SRF) would delay the ignition point by
about 2 m and lower the intensity and temperature of the kiln flame
compared to a fossil fuel flame. This is related to a larger particle
size and moisture content of the alternative fuels, which lowers the
conversion rate compared to fossil fuels. The consequences can be
a lower kiln temperature and cement quality. The longer conversion
time may also lead to the possibility of localized reducing conditions
in the cement kiln, which can have a negative impact on the clinker
quality and process stability. The burner design may alleviate some
of the issues encountered with SRF cofiring. At one of the test plants
the burner was changed from a design with an annular channel for axial
air to a jet design. This proved to be beneficial for an early ignition
and improved dispersion of the fuel and led to an increase in cement
quality and higher use of SRF

Impact of Dry Solids and Bile Acid Concentrations on Bile Acid Binding Capacity of Extruded Oat Cereals
An agricultural geography of some semi-arid parts of the Mediterranean region in relation to the agricultural problems of West Punjab
This study has been
divided into four principal parts. In the first part the physical
background has been described. The chapter on structure and relief
purports to give only an outline in the context of which the other
physical and cultural factors may be considered. Detailed descriptions
of areas studied closely in the field or from large-scale maps
has been given under agricultural regions. The account of climate,
hydrography, vegetation and soil similarly treats only of essentials
in relation to agriculture and its problems. The factor of variabil¬
ity of rainfall in Barbary has been given.special attention and
some correlations have been established, i.e. between autumn rainfall
and the total area sown and between spring rainfall and the yields.The second part treats of the cultural background. In this
section, two aspects have been studied in special detail. European
colonization in Barbary and its impact on the native cultivators
of Barbary has been discussed in relation to its history and development. The modes of life and settlement in Barbary have been described
regionally after a detailed examination of physical, cultural and
economic factors.In the third part a number of outstanding agricultural
problems have been examined in considerable detail with special
reference to recent developments. The account of irrigation
embraces the traditional and modern systems, their influence on
crops and on the cultivators. Settlement of newly irrigated regions
has also been examined in some detail. For Barbary the problem
has been documented by studies in the field. Thereafter, water¬
logging and saline soils, soil erosion and dry-farming are treated
rather generally mainly on the basis of documentary material.
Attention has however been drawn to the most pressing problems to
be faced today and the types of solutions that have been attempted.The final part includes first an account of land-use and
agricultural methods.followed by a brief description of the product¬
ion and distribution of principal crops. Then, in the chapters on
agricultural regions, all the factors described earlier have been
integrated. Most of the micro-geographical studies made in the
field and from 1:50,000 maps are incorporated into these chapters.
The division of Barbary into agricultural regions and their
detailed description with the help of sample regional and farm
studies thus constitutes the principal result of this study.A brief account of present attempts towards modernisation
is followed by the Conclusion in which several constructive
suggestions have been made in relation to the population problem
and the low standard of living.Throughout the study, the emphasis has been placed on
Barbary which was the region studied in the field and on which
a large proportion of documentary research war carried out.
West Punjab stands, as it were, in the background. A fuller
understanding of the agricultural landscape and of the problems
of agriculture which has followed the study of Barbary may
later lead on to an attempt at a closer survey of West Punjab
on the basis of field work
