We report the measure of prostate-specific antigen (PSA) from extracts of blood dried on filter paper. Five 3-mm (diameter) paper discs containing approximately 25 microL of dried whole blood were punched from the filter paper and extracted with 500 microL of buffer. Recovery of PSA was > 92%. Imprecision of the filter paper procedure was <10% when corresponding whole-blood concentrations were ...
BACKGROUND Although studies have provided estimates of premature deaths attributable to either heat or cold in selected countries, none has so far offered a systematic assessment across the whole temperature range in populations exposed to different climates. We aimed to quantify the total mortality burden attributable to non-optimum ambient temperature, and the relative contributions from heat...
Occupational health is particularly affected by high heat exposures in workplaces, which will be an increasing problem as climate change progresses. People working in jobs of moderate or heavy work intensity in hot environments are at particular risk, owing to exposure to high environmental heat and internal heat production. This heat needs to be released to protect health, and such release is ...
Abstract: Vitamin D deficiency is widespread in Saudi Arabia. The aim of this study was to explore participants' knowledge about vitamin D and attitudes toward sun exposure. The study also aimed to explore the social and cultural factors that might potentially contribute to vitamin D deficiency in Saudi Arabia. Face-to-face interviews were carried out in the cities of Jeddah and Makkah between ...
I . The dietary intake, and urinary, cutaneous and faecal loss of water, sodium, potassium and iron have been studied in young men living and performing moderate work in a hot climate. The dietary intakes of K and Fe were lowered during part of the study. 2. The subjects were already somewhat acclimatized to heat; further acclimatization was achieved when they were performing work, and this was...
We compared diurnal patterns of vaginal temperature in lactating cows under grazing conditions to evaluate genotype effects on body temperature regulation. Genotypes evaluated were Holstein, Jersey, Jersey x Holstein and Swedish Red x Holstein. The comparison of Holstein and Jersey versus Jersey x Holstein provided a test of whether heterosis effects body temperature regulation. Cows were fitte...
Food sustainability is a significant global concern with drastic change required to mitigate complex social, environmental and economic issues like climate change and food security for an ever increasing population. In this paper, we investigate the roles that digital interactions might play in bringing about more sustainable food consumption practices. To inform this exercise, we set out to un...
Although now over 100 years old, the classification of climate originally formulated by Wladimir Köppen and modified by his collaborators and successors, is still in widespread use. It is widely used in teaching school and undergraduate courses on climate. It is also still in regular use by researchers across a range of disciplines as a basis for climatic regionalisation of variables and for as...
Residential buildings are the main consumer of materials in construction industry. Selection of appropriate materialled to a great impact on quality of architecture in many aspects. Considering the extent of construction in the residential sector, study on this context seems necessary. Therefore the aim of this study is to represent a “materials selection model” for residential building facade ...
While in the historic urban fabric of Iran's cities, there are numerous traditional buildings that have stood up for more than one hundred years, today's buildings, in spite of advanced construction technologies, are not comparable with those traditional ones in terms of resiliency and durability. The sustainable vernacular strategies in design and construction of these traditional houses are t...
