Screening for childhood anaemia using copper sulphate densitometry
… of this study was to evaluate copper sulphate densitometry as a screening method for anaemia in children. The accuracy of copper sulphate densitometry was also compared to clinical assessment for the presence of pallor and haemoglobin measurement with a BMS-haemoglobinometer. Different …

Measurement of Liquid Film in Annular Flow Using X-Ray Densitometry
… analysis codes. This thesis evaluates x-ray densitometry as a non-intrusive alternative that measures film thickness without flow disturbance. Film thickness measurements were obtained for two-phase annular flow in a 9.5 mm pipe across various superficial gas and liquid velocities and …

Type IV Pili-Dependent Secretion of Biofilm Matrix Material Proteins in Clostridium perfringens
… construct, it was concluded from immunoblot densitometry data that, except for the pilA1 deletion mutant, none of the 18 tested pilin mutants had a statistically significant difference from the wild type (WT) with regard to protein secretion. From slot blot densitometry assays, it was …

Women's Actions Related to Health Behaviors after Receiving Bone Mineral Density Results: An Exploratory Study
Bone densitometry is the only clinically acceptable and objective method for the accurate measurement of bone mineral density (BMD), bone mass, and the prediction of bone fracture risk. Dual energy X-ray absorptiometry (DXA) is the primary diagnostic bone densitometry tool used in clinical …

Effects of Ovariectomy and Anatomical Position on the Compact Bone As Seen in Three Month Summer Ovine Model
… osteons per field, and the mean osteon area. Densitometry analysis was also performed using the microradiographs using image analysis and the use of an aluminum step wedge on each microradiograph as a key. Once all of the data was collected a 2-way repeated measures ANOVA statistical analysis …

Dendroclimatology of Pinus sylvestris L. in the British Isles
… Ireland is described. The technique of x-ray densitometry is used to measure density. It is shown that it is possible to use x-ray densitometry on well preserved sub-fossil pine. Chronologies have been constructed for parameters of earlywood and latewood widths, ring-width, maximum and minimum …

Over-expression in Escherichia coli of the ToxA51 llama single domain antibody targeting Clostridium difficile enterotoxin A
… quantification was performed using SDS-PAGE densitometry while binding activity against TcdA was assessed via Biacore. Our studies also led to medium simplification for small-scale expression, shorter expression time and simpler purification process without impairing on the quality of the …

Material Differences in Equine Cortical and Trabecular Bone
… sections of the equine metacarpus, underwent densitometry analysis and were statistically analyzed. The majority of results suggest that the material is the same between varying densities of bone and thus the same between cortical and trabecular bone. These particular results are consistent …

Arachidonate 15-lipoxygenase and ubiquitin as potential fertility markers in boars
… western blotting with computerized densitometry using antibodies against 15-LOX and UBI. Fertility data including FR and TNB was collected from sows mated to the boars in the study. Correlation coefficient analysis found moderate, negative relationships between FRs and DCDs (-0.39, …

An Unprecedented Research Project into the Alcohol Retention Variation of Flavored Spirits
… on ABV were tested through distillation, densitometry, and nuclear magnetic resonance spectroscopy (NMR). Given the results based on NMR data and NaCl additions, intermolecular hydrogen bonding is not the direct cause of the ethanol retention. However, a direct correlation between …

Comparison of Pharmacologic Treatment on Bone Mineral Density in Patients with Osteopenia
… diagnosed as having osteopenia with bone mineral densitometry in the health promotion center of a hospital from January, 2002 to October, 2006. We compared bone density between 3 groups of no treatment, calcium and vitamin D supplement and bisphosphonate treatment before and after 1 year …

An analysis of the periodicity of the cell cycle and apoptotic regulatory proteins in prostate xenografts using anova and cosinor methods
… method, and the results were assessed by densitometry. Statistical analysis of the mice with the ANOVA and the COSiNOR methods showed that selenium treatment was most effective at HALO 13 at decreasing cell cycle and apoptosis-related proteins for ALVA-3 1. For PC-3 tumor lines, HALO 7 …

Effects of season and plane of nutrition upon serum lipids and protein of white-tailed deer
… lipid and protein fractions were determined by densitometry. Significant differences between seasons were found for fatty acids, lecithins, and alpha globulin in the wild deer. No tests for seasonal differences were made for captive deer. Three regression equations were developed to describe the …
