Abstract
OBJECTIVE To investigate the accuracy of human listeners in identifying epileptic seizures and seizure lateralisation from audified EEG signals. METHODS EEG data from 17 temporal lobe epilepsy patients (9 male, 8 female; aged 23-55) was converted to audio format by 60× time compression. Using a subset of 19% of the data, five auditory participants (2 female, 3 male; aged 23-58) were trained to identify seizures and their lateralisation by listening to audified EEG signals from difference electrodes P3-T5 and P4-T6. Following training, seizure detection performance of the auditory participants was tested using the remaining data. RESULTS Allowing a 5s auditory time margin for successful detection, the mean sensitivity of the five auditory participants was 89.6% (SD 8.3%) with a false detection rate of only 0.0068/h (SD 0.0077/h). The mean accuracy of seizure lateralisation identification was 77.6% (SD 7.1%). CONCLUSIONS With a limited amount of training, humans can detect seizures and seizure lateralisation from audified EEG signals of electrodes P3-T5 and P4-T6 with accuracy comparable to visual assessment of full EEG traces (21 electrodes) by an expert encephalographer. SIGNIFICANCE A more efficient and accurate clinical tool for assessing EEG data based on audification may be developed, which will improve diagnosis and treatment of epilepsy.

Abstract
Celiac disease is an underdiagnosed condition in children with variable manifestations. Presenting symptoms in children are changing over time, are impacted by age and geography, and are distinct from those of adults with this disease. Prompt diagnosis of celiac disease in affected children may avoid growth and nutritional deficits in addition to preventing long term disease complications such as infertility and malignancy. Diagnosis and management of celiac disease in children requires expert medical and nutritional care to maximize positive outcomes.

Abstract
Stimulated by retinoic acid 8 (STRA8) is a protein that is required for meiotic initiation in both male and female gametes in vertebrates. It is also expressed in embryonic germ cells and neonatal male germ cells of mice. The utility of using the Stra8 promoter to recognise and isolate pre-meiotic male germ cells has been reported by others in the mouse. In order to mark germ cells in male pigs, we cloned 1.6 kb of the mouse Stra8 promoter and used it to develop a reporter plasmid using mitochondrial-localised enhanced yellow fluorescent protein (mEYFP). The Stra8-mEYFP transgenic male pigs were produced using somatic cell nuclear transfer. The mEYFP reporter was expressed and easily detectable in the live germ cells of the mature animals and could be observed during tissue culture. The mitochondrial-localised expression of the EYFP reporter was helpful in observing the size and stage of the germ cell. The mEYPF protein was found to be expressed only in the testis of the transgenic pigs using Western blot analysis, whereas endogenous STRA8 protein was also detected in the lung and brain. Fluorescent immunohistochemistry of testicular sections of the transgenic pigs indicated a similar expression pattern to that of the endogenous STRA8 protein. There was an overlap in the expression of the mEYFP and the endogenous STRA8 protein; however, it was observed that the mEYFP protein was present at an earlier stage of spermatogenesis than the STRA8 protein. Immunocytochemistry performed on plated tubules similarly showed varying intensity in expression between the mEYFP transgene and the endogenous STRA8. The difference in the timing of protein expression may be due to the model created or the use of the mouse Stra8 promoter for the expression of mEYFP. Alternatively, the lag in expression between that of the endogenous STRA8 and mEYFP protein may be due to attenuated translation of the Stra8 mRNA. This transgenic model should be useful for the study of reproduction, development, transplantation, biotechnology, and culture of the pig male germ line.

Abstract
The two hormones prolactin and growth hormone exhibit considerable structural homology as well as exerting similar biological effects, especially the primate hormones. One effect of prolactin that deserves greater attention is its action on the immune system including the stimulation of growth of experimental lymphomas, both in vivo and in vitro. One cultured lymphoma cell line has proved to be a very useful model system in which to examine prolactin receptor synthesis and turnover as well as post-receptor mechanisms of action. Prolactin and growth hormone receptors from rabbit mammary gland and liver respectively have been partially purified and characterized. Polyclonal antibodies to prolactin and growth hormone receptors have been generated. The antibodies have been shown to cross-react with prolactin or growth hormone receptors from a number of species, indicating structural homology among receptors as well as hormones. The polyclonal antisera inhibit the action of prolactin in vivo as well as in vitro. In addition, several of the same antisera also mimic the action of prolactin. As yet the presence of autoantibodies to prolactin or growth hormone receptors in human serum samples has not been recognized.

Abstract
The purpose of the current study was to evaluate the role of visible light during trophic transfer of the essential metalloid, selenium (Se) from sediments by way of the microalgae Phaeodactylum tricornutum to bivalves. Initial experiments compared uptake of Se with algal cell number after deposit-feeding (Tellina deltoidalis) and filter-feeding (Soletellina alba) bivalves were exposed for 12 days under 16:8 h light:dark and 24-hour dark regimes to sediments amended with Se (17 mg/kg dry weight). Comparisons of filter-feeding with deposit-feeding organisms indicated >2-fold higher body burdens in the deposit-feeding organisms after 12 days. Darkness failed to significantly and consistently diminish algal cell densities. However, general trends indicated a decrease of pelagic algal numbers in +Se/dark treatments during the 12-day exposure. To determine whether time-dependent patterns were present in the uptake of Se by the deposit-feeding species, a second experiment was conducted using Se-laden sediments under light and dark conditions. Algal cell counts were measured and Se concentrations determined in animals sampled at days 0, 3, 6, 9, and 12. Deposit-feeding animals maintained in the dark accumulated, Se more rapidly than animals on light to dark cycles until 12 days at which time no significant differences were observed between treatments. Concentrations of Se in tissues of deposit-feeding bivalves were not directly related to algal cell density in lighted or dark chambers. These results indicate that pelagic microalgae may only play a key role in Se uptake during early hours of exposure, and feeding behavior may be a more important factor in deposite-feeding bivalves.
