Peptic ulceration of the oesophagus in combination with partial thoracic stomach
The subject - "Peptic Ulceration of the Oesophagus
in combination with Partial Thoracic Stomach" - is one
which has been recognised only within the past few years.
It has been my fortune, as radiologist to a large teaching
hospital, to find over twenty cases during the past five
years. The thesis reviews the pathogenesis and clinical
features together with a description of diagnostic methods
and treatment. The appendix contains full clinical notes
of eighteen cases which have been under treatment and
observation for more than a year.
The clinical importance in recognising the condition
lies in the fact that the alternative diagnosis is cancer
of the lower end of the oesophagus. Peptic ulceration
is not uncommon and if erroneously treated by radiotherapy
the results might prove disastrous.
The academic interest of the subject centres round
the lower end of the oesophagus and the partial thoracic
stomach. The congenital and acquired types of gastric
herniation through the oesophageal hiatus are fully discussed
and the accepted anatomical site of the cardia is called
into question. As regurgitation into the oesophagus plays
a large part in the production of peptic ulceration this
point assumes considerable importance. The recognition of
the position of the cardia in relation to neighbouring structures
is most readily determined by radiology and stress is laid on
the distinguishing features

The dynamic nature of DNA-strand breaks present in differentiating muscle cells and quiescent lymphocytes
AbstractCellular differentiation in a number of eukaryotic systems is associated with changes in the number of DNA-strand breaks and involves the activity of adenosine diphosphoribosyl transferase (ADPRT). DNA-strand breaks are essential for activation of nuclear ADPRT, the activity of which is required for efficient religation of DNA-strand breaks. In this study we demonstrate the dynamic nature of DNA-strand breaks formed in the genome of differentiating avian skeletal muscle cells and quiescent human lymphocytes. Inhibition of ADPRT activity blocks DNA-strand ligation in both cell types and leads to the accumulation of a higher number of strand breaks.DNA-strand breakADP-ribosylationDifferentiationMitogen activatio

Response of the Agile Antechinus to Habitat Edge, Configuration and Condition in Fragmented Forest
Habitat fragmentation and degradation seriously threaten native animal communities. We studied the response of a small marsupial, the agile antechinus Antechinus agilis, to several environmental variables in anthropogenically fragmented Eucalyptus forest in south-east Australia. Agile antechinus were captured more in microhabitats dominated by woody debris than in other microhabitats. Relative abundances of both sexes were positively correlated with fragment core area. Male and female mass-size residuals were smaller in larger fragments. A health status indicator, haemoglobin-haematocrit residuals (HHR), did not vary as a function of any environmental variable in females, but male HHR indicated better health where sites' microhabitats were dominated by shrubs, woody debris and trees other than Eucalyptus. Females were trapped less often in edge than interior fragment habitat and their physiological stress level, indicated by the neutrophil/lymphocyte ratio in peripheral blood, was higher where fragments had a greater proportion of edge habitat. The latter trend was potentially due to lymphopoenia resulting from stress hormone-mediated leukocyte trafficking. Using multiple indicators of population condition and health status facilitates a comprehensive examination of the effects of anthropogenic disturbances, such as habitat fragmentation and degradation, on native vertebrates. Male agile antechinus' health responded negatively to habitat degradation, whilst females responded negatively to the proportion of edge habitat. The health and condition indicators used could be employed to identify conservation strategies that would make habitat fragments less stressful for this or similar native, small mammals
