The Canine Connection: an anthropologically grounded philosophical perspective on caring for dogs
Most philosophical discussions of moral consideration for animals focus on
animals as a single category, neglecting to differentiate them by type or role (such as
wild, domestic, laboratory, or companion). Moreover, the importance of the individual
animal in terms of relationship to humans is de-emphasised.
Animals should not be discussed as a monolithic group. In this thesis the dog is
utilized as the paradigmatic animal to demonstrate that philosophical discourse on the
ethics of consideration for animals must reflect the diversity present within the group
labeled "animals". The major philosophical theories advocating moral consideration of
animals are summarized, noting that all animals are discussed as one category.
Anthropological evidence is provided to demonstrate the historical nature of the human-dog
bond. The ethics of care provides the foundation for the claim that dogs have
relational value and thus persons have the moral obligation to care for them
Complexity of Fetal Movement Detection Using a Single Doppler Ultrasound Transducer
The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the gestation ages of31 to 41 weeks. Using a computer-controlled SVHS PC-VCR, the instrumental detection of fetal movements was time-linked with real-time video ultrasound. This allowed the fetal movements to be scored by expert examiners on a second-per-second basis. A total of 52,478 seconds of fetal movements was scored using this system. Neither system could accurately define the entire duration, velocity, or magnitude of the fetal movements as detected by real-time ultrasound. The complexity of detecting fetal movements using only one transducer has many shortcomings, such as: the amplitude of the returning Doppler signal, the small area of the fetus monitored by a single transducer, the position of the fetus, the type and variety of fetal movements, and material size and shape

Symmetric Skyrmions
We present candidates for the global minimum energy solitons of charge one to
nine in the Skyrme model, generated using sophisticated numerical algorithms.
Assuming the Skyrme model accurately represents the low energy limit of QCD,
these configurations correspond to the classical nuclear ground states of the
light elements. The solitons found are particularly symmetric, for example, the
charge seven skyrmion has icosahedral symmetry, and the shapes are shown to fit
a remarkable sequence defined by a geometric energy minimization (GEM) rule. We
also calculate the energies and sizes to within at least a few percent
accuracy. These calculations provide the basis for a future investigation of
the low energy vibrational modes of skyrmions and hence the possibility of
testing the Skyrme model against experiment.Comment: latex, 9 pages, 1 figure (fig1.gif
Health social movements and the hybridisation of ‘cause regimes’: an ethnography of a British childbirth organisation
This article reports on an ethnographic study of the UK’s largest health advocacy organisation dedicated to pregnancy, childbirth and parenting, the National Childbirth Trust or NCT. Working from interview data, textual materials and fieldnotes, we articulate three key phases in the NCT’s historically shifting relationships to feminism, medicine, the state and neoliberal capitalism. The concept of folded cause regimes is introduced as we examine how these phases represent the hybridisation of the organisation’s original cause. We argue that for the NCT the resulting multiplicity of cause regimes poses significant challenges, but also future opportunities. The apparent contradictions between cause regimes offer important insights into contemporary debates in the sociology of health and illness and raises critical questions about the hybrid state of health advocacy today. Focussing on cause allows for a deeper understanding of the intense pressures of diversification, marketisation and the professionalization of dissent faced by third sector organisations under current social and economic conditions
An LC-MS/MS-Based Method for the Quantification of Pyridox(am)ine 5'-Phosphate Oxidase Activity in Dried Blood Spots from Patients with Epilepsy
We report the development of a rapid, simple, and robust LC-MS/MS-based enzyme assay using dried blood spots (DBS) for the diagnosis of pyridox(am)ine 5'-phosphate oxidase (PNPO) deficiency (OMIM 610090). PNPO deficiency leads to potentially fatal early infantile epileptic encephalopathy, severe developmental delay, and other features of neurological dysfunction. However, upon prompt treatment with high doses of vitamin B6, affected patients can have a normal developmental outcome. Prognosis of these patients is therefore reliant upon a rapid diagnosis. PNPO activity was quantified by measuring pyridoxal 5'-phosphate (PLP) concentrations in a DBS before and after a 30 min incubation with pyridoxine 5'-phosphate (PNP). Samples from 18 PNPO deficient patients (1 day-25 years), 13 children with other seizure disorders receiving B6 supplementation (1 month-16 years), and 37 child hospital controls (5 days-15 years) were analyzed. DBS from the PNPO-deficient samples showed enzyme activity levels lower than all samples from these two other groups as well as seven adult controls; no false positives or negatives were identified. The method was fully validated and is suitable for translation into the clinical diagnostic arena
Oestradiol-17β plasma concentrations after intramuscular injection of oestradiol benzoate or oestradiol cypionate in llamas (Lama glama)
<p>Abstract</p> <p>Background</p> <p>Llamas (<it>Lama glama</it>) are induced ovulators and the process of ovulation depends on dominant follicular size. In addition, a close relationship between behavioural estrus and ovulation is not registered in llamas. Therefore, the exogenous control of follicular development with hormones aims to predict the optimal time to mate. Oestradiol-17β (E<sub>2</sub>) and its esters are currently used in domestic species, including camelids, in synchronization treatments. But, in llamas, there is no reports regarding the appropriate dosages to be used and most protocols have been designed by extrapolation from those recommended for other ruminants. The aim of the present study was to characterize plasma E<sub>2 </sub>concentrations in intact female llamas following a single intramuscular (i.m.) injection of two oestradiol esters: oestradiol benzoate (EB) and oestradiol cypionate (ECP).</p> <p>Methods</p> <p>Twelve non pregnant and non lactating sexually mature llamas were i.m. injected on day 0 with 2.5 mg of EB (EB group, n = 6) or ECP (ECP group, n = 6). Blood samples were collected immediately before injection, at 1, 6, 12, 24 h after treatment and then daily until day 14 post injection. Changes in hormone concentrations with time were analyzed in each group by analysis of variance (ANOVA) using a repeated measures (within-SS) design. Plasma E<sub>2 </sub>concentrations and area under the concentration-time curve (AUC) values were compared between groups by ANOVA. In all cases a Least-Significant Difference test (LSD) was used to determine differences between means. Hormonal and AUC data are expressed as mean ± S.E.M.</p> <p>Results</p> <p>Peak plasma E<sub>2 </sub>concentrations were achieved earlier and were higher in EB group than in ECP group. Thereafter, E<sub>2 </sub>returned to physiological concentrations earlier in EB group (day 5) than in ECP group (day 9). Although plasma E<sub>2 </sub>profiles differed over time among groups there were no differences between them on AUC values.</p> <p>Conclusions</p> <p>The i.m. injection of a single dose of both oestradiol esters resulted in plasma E<sub>2 </sub>concentrations exceeding physiological values for a variable period. Moreover, the plasma E<sub>2 </sub>profiles observed depended on the derivative of oestradiol administered. This basic information becomes relevant at defining treatment protocols including oestrogens in llamas.</p
