Maternal Haemoglobin and outcome of pregnancy
Background: The association between maternal haemoglobin concentration and the outcome of pregnancy has been a source of continual controversy. Preterm delivery and low birth weight are major causes of stillbirths and early neonatal deaths. Pre-eclampsia is a major complication which occurs during …

Studies on the degradation of haemoglobin
The chemical relationship which exists between haemoglobin and bile pigments was first established in 1933, when, after monumental studies covering a period of 24 years, Hans Fischer and his colleagues succeeded in synthesizing bile pigments and protoporphyrin. He thereby demonstrated the …

Preterm intraventricular haemorrhage - Effects of extracellular haemoglobin
… of red blood cells causes release of cell-free haemoglobin (Hb), which will with time further degrade releasing the toxic substances hemin, free iron, and various ROS (reactive oxygen species). Metabolites of cell-free Hb have been identified as an initiator of inflammation in the context of …

Genetic basis of hereditary persistence of fetal haemoglobin
… underlie the variations observed in fetal haemoglobin (HbF) levels. This is important as it is known that an elevated HbF level can ameliorate the symptoms of many of the haemoglobinopathies. The frequency and range of hereditary persistence of fetal haemoglobin (HPFH) in the UK population …

Effect of iron and haemoglobin on Staphylococcus aureus biofilms
… as an important signal for biofilm induction. Haemoglobin is the most abundant iron source in the host and S. aureus has the appropriate uptake system to acquire it, hence, this thesis questions the role of haemoglobin in biofilm formation. In this study, it was used a physiological medium …

The non-invasive quantification of cutaneous haemoglobin and its oxygenation by reflectance spectrophotometry
… between the absorbances of oxy and reduced haemoglobin, two indices were defined for quantifying the amount of haemoglobin, the "haemoglobin index", and oxygen saturation, the "oxygenation index", in a blood containing sample. The haemoglobin index is derived from the spectrum of haemoglobin …

Characterisation of two genetic loci involved in fetal haemoglobin production: BCLIIA and HBSIL-MYB intergenic region
The continuous production of fetal haemoglobin (HbF, a2Ya) into adulthood is an ameliorating factor in sickle cell disease and B-thalassemia. We have previously mapped two quantitative trait loci (QTLs) controlling HbF levels, one in intron 2 of BCL11A gene, and the other, an intergenic region on …

The relationship between faecal haemoglobin concentration and risk of significant colorectal neoplasia in screening and symptomatic populations.
Faecal immunochemical tests for haemoglobin (FIT) are replacing traditional guaiac-based faecal occult blood (gFOBT) tests in bowel screening programmes due to their many advantages. An evaluation of using quantitative FIT within the Scottish Bowel Screening Programme (SBSP) has taken place with …

Habits, hassle, and health: how do blood donors respond to a temporary deferral due to low haemoglobin?
… month deferral from giving blood due to a low haemoglobin (Hb) concentration. The aims were two-fold: first, to quantify the effect of a temporary deferral on donation patterns once eligible to return, and second, to identify the processes contributing to the effect. The mixed methods design …

Development and optimisation of pre-treatment procedures to enhance total haemoglobin for carboxyhaemoglobin analysis in diluted blood samples
… taste and odour. When CO is inhaled, it binds to haemoglobin in red blood cells and forms carboxyhaemoglobin (COHb). Used as a biomarker to investigate CO exposure, COHb can be determined in blood using a spectrophotometry-based technique called CO-oximetry. One of the challenges with certain …

Studies into solid core drug delivery system using haemoglobin as a model drug and supercritical fluid processing for encapsulation
… of proteins using silica as core material, haemoglobin as model drug and supercritical fluid processing as encapsulation technique. Silica particles of different morphology were used as a carrier material for protein immobilisation and fatty acids coating was performed using supercritical …
