ECENTLY, a new system for performing blood counts has been introduced. This is stated to eliminate the major sources of error, i.e., those of drawing blood to a mark accurately, and making an accurate dilution.’3 The basis of this system is a self-filling, disposable glass mioropipette,#{176} combined with a plastic container, prefilled with a suitable diluent. From a single blood sample a hemo...

A radio assay employing 14C-uridine to measure the intracellular killing of Candida albicans by phagocytes is presented. The principle of this new method is that after killing of Candida albicans by phagocytes RNA synthesis stops and therefore uridine uptake is diminished whilst viable candida in cultures would take up uridine and as a result, high CPM counts can be obtained within 135 min...

background: although enteral feeding solutions are used to reduce the morbidity and mortality in many malnourished and hospitalized patients, microbial contamination of these products may lead to severe infections, especially in immune suppressed ones. the aim of this study was to evaluate the microbiological quality of commercial enteral feedings in two hospital settings in shiraz. methods: tw...

Snowshoe hare (Lepus americanus) pellet surveys are an efficient tool for monitoring population trends, but there is no standard methodology used to conduct surveys. To assist researchers in developing protocols, we evaluated pellet-decay rates and aging in 3 snowshoe hare habitat types in Alaska during the peak and decline of the hare population from 1999–2002. We found significant differences...

leucocytes in the Coulter counter. These procedures are J andglutamic performed separately and require two tubes and two eluates from diluting pipettes. The purpose of this paper is to describe a system which enables the haemoglobin estimation and leucocyte count to be made from the one diluted sample. The system dispenses with the need for pipettes and ,oncentration. diluting tubes and enables...

A new model for source counts from 8-1100 μm is presented, which agrees well with source-count data and the observed background spectrum. The model is similar to that of Rowan-Robinson (2001), but with different evolution for each of the four assumed infrared template types. The evolution is modified in two ways; (i) the exponential factor is modified so that it tends to a constant value at lat...

This paper proposes a new spatial multivariate count model to jointly analyze the traffic crashrelated counts of pedestrians and bicyclists by injury severity. The modeling framework is applied to predict injury counts at a Census tract level, based on crash data from Manhattan, New York. The results highlight the need to use a multivariate modeling system for the analysis of injury counts by r...

Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...

Magnetic resonance imaging (MRI) has been established as the most relevant paraclinical tool for diagnosing and monitoring multiple sclerosis (MS). In this context, counting the number of new enhancing lesions on monthly MRI scans is widely used as a surrogate marker of MS activity when evaluating the effect of treatments. In this study, we investigated whether parametric models based on mixed ...
