The Byzantine Church of the Nutrition in Nazareth rediscovered

Although Nazareth has usually been seen by scholars as a relatively minor Byzantine pilgrimage centre, it contained perhaps the most important ‘lost��� Byzantine church in the Holy Land, the Church of the Nutrition ‐ according to De Locis Sanctis built over the house where it was believed that Jesus Christ had been a child. This article, part of a series of final interim reports of the PEF-funded ‘Nazareth Archaeological Project’, presents evidence that this church has been discovered at the present Sisters of Nazareth convent in central Nazareth. The scale of the church and its surrounding structures suggests that Nazareth was a much larger, and more important, centre for Byzantine-period pilgrimage than previously supposed. The church was used in the Crusader period, after a phase of desertion, prior to destruction by fire, probably in the 13th century.

Children of the golden minster: St. Oswald's Priory and the impact of industrialisation on child health.

This study explores the disease experience of children buried within the cemetery of St. Oswald’s Priory, Gloucester from AD1153 to 1857. Evidence for ages-at-death, infant mortality, and the prevalence of stress indicators, trauma, and pathology were compared between the early and postmedieval periods. The skeletal remains of these children provide evidence for child health spanning the economic expansion of Gloucester at St. Oswald’s, from a mostly rural parish to a graveyard catering for families from the poorer northern part of the town and the workhouse. Results showed that the children from the postmedieval period in Gloucester suffered higher rates of dental caries (38%) and congenital conditions (17.3%) than their counterparts from the early and later medieval period. This paper serves to highlight the value of nonadult skeletal material in the interpretation of past human health in transitional societies and illustrates the wide variety of pathological conditions that can be observed in nonadult skeletons.

Response of the lower St. Lawrence Estuary to external forcing in winter

Mostly because of a lack of observations, fundamental aspects of the St. Lawrence Estuary's wintertime response to forcing remain poorly understood. The results of a field campaign over the winter of 2002/03 in the estuary are presented. The response of the system to tidal forcing is assessed through the use of harmonic analyses of temperature, salinity, sea level, and current observations. The analyses confirm previous evidence for the presence of semidiurnal internal tides, albeit at greater depths than previously observed for ice-free months. The low-frequency tidal streams were found to be mostly baroclinic in character and to produce an important neap tide intensification of the estuarine circulation. Despite stronger atmospheric momentum forcing in winter, the response is found to be less coherent with the winds than seen in previous studies of ice-free months. The tidal residuals show the cold intermediate layer in the estuary is renewed rapidly ( 14 days) in late March by the advection of a wedge of near-freezing waters from the Gulf of St. Lawrence. In situ processes appeared to play a lesser role in the renewal of this layer. In particular, significant wintertime deepening of the estuarine surface mixed layer was prevented by surface stability, which remained high throughout the winter. The observations also suggest that the bottom circulation was intensified during winter, with the intrusion in the deep layer of relatively warm Atlantic waters, such that the 3 C isotherm rose from below 150 m to near 60 m.

The significance of "nonsignificance" in randomized controlled studies: a discussion inspired by a double-blinded study on St. John's Wort (Hypericum perforatum L.) for premenstrual symptoms

Objectives: This study aimed to investigate the efficacy of St. John's wort extract (SJW) as a treatment for premenstrual symptoms. Design: The study was a randomized, double-blinded, placebo-controlled trial, with two parallel treatment groups. After a no-treatment baseline cycle, volunteers were randomized to either SJW or placebo for a further two menstrual cycles. Settings/location: A postal trial conducted from The University of Reading, Berkshire, England. Subjects: One hundred and sixty-nine (169) normally menstruating women who experienced recurrent premenstrual symptoms were recruited onto the study. One hundred and twenty-five (125) completed the protocol and were included in the analysis. Interventions: Six hundred milligrams (600) mg of SJW (standardized to contain 1800 mug of hypericin) or placebo (containing lactose and cellulose). Outcome measure: A menstrual diary was used to assess changes in premenstrual symptoms. The anxiety-related subgroup of symptoms of this instrument was used as the primary outcome measure. Results: After averaging the effects of treatment over both treatment cycles it was found that there was a trend for SJW to be superior to placebo. However, this finding was not statistically significant. Conclusion: The possibility that this nonsignificant finding resulted from insufficient statistical power in the study, rather than a lack of efficacy of SJW, is discussed. Following this discussion the recommendation is made that, in future, similar studies should be powered to detect a minimum clinically relevant difference between treatments.
