Articles

The Mozambique Eyecare Project was an international partnership to implement and research eye health education in Mozambique and the Africa region. An optometry degree was developed at Universidade Lúrio, Mozambique. In addition, existing eye health workers were upskilled with training. Researchers from various disciplines evaluated the project and its potential for impact on eye health in the region. The body of evidence generated from the research provides useful lessons for development programmes in general, as well as specific lessons for delivering eye health education and service delivery models for low income settings.

The Relationship Between Maternal Plasma Homocysteine In Early Pregnancy And Birth Weight, Shona Cawley, Eimer O'Malley, Rachel Kennedy, Ciara Reynolds, Anne Molloy, Michael Turner

Articles

Background: There is limited evidence that plasma homocysteine (Hcy) is increased in women with adverse pregnancy outcomes, such as low birth weight (LBW).

Objective: We examined the relationship between maternal Hcy at the first prenatal visit and birth weight.

Study design: In a prospective observational study, women were recruited during their first prenatal visit after sonographic confirmation of gestational age. Along with the standard tests, blood was also taken for the measurement of maternal serum and red blood cell (RBC) folate, vitamin B12, and Hcy. In addition to collecting standard clinical and sociodemographic details, a detailed questionnaire on vitamin supplementation …

An Investigation Of Therapeutic Rapport Through Prosody In Brief Psychodynamic Psychotherapy, Carolina De Pasquale, Charlie Cullen, Brian Vaughan

Conference Papers

Therapeutic alliance, a concept closely related to rapport, is one of the most important variables in psychotherapy. High degrees of synchrony/coordination in the therapeutic session are considered to contribute to rapport, and have received attention in the psychotherapy literature. Coordinative behaviours are observable in speech, and they manifest in phenomena such as prosodic accommodation, a dynamic phenomenon closely related to conversational success. A preliminary investigation of interpersonal prosodic dynamics in psychotherapy was performed on a database obtained in collaboration with the University of Padua, consisting of 16 recordings making up the entire course of a brief psychodynamic psychotherapy intervention for …

Nanostructured Materials For Food Applications: Spectroscopy, Microscopy And Physical Properties, Shubham Sharma, Swana Jaiswal, Brendan Duffy, Amit Jaiswal

Articles

Nanotechnology deals with the matter of atomic or molecular scale. Other factors that define the character of a nanoparticle are its physical and chemical properties, such as surface area, surface charge, hydrophobicity of the surface, the thermal stability of the nanoparticle, and its antimicrobial activity. A nanoparticle is usually characterized by using microscopic and spectroscopic techniques. Microscopic techniques are used to characterize the size, shape, and location of the nanoparticle by producing an image of the individual nanoparticle. Several techniques, such as scanning electron microscopy (SEM), transmission electron microscopy/high resolution transmission electron microscopy (TEM/HRTEM), atomic force microscopy (AFM) and scanning …

Avoiding Maternal Vitamin D Deficiency May Lower Blood Glucose In Pregnancy, Méabh Walsh, Linnea Bärebring, Hanna Augustin

Articles

Background Vitamin D status is hypothesised to play a role in gestational glucose control. No studies to date have examined vitamin D in relation to changes in blood glucose in pregnancy. Thus, the aim was to examine if vitamin D in early pregnancy and vitamin D trajectory associate with blood glucose trajectory over pregnancy in a Swedish cohort. We also investigated the relation between maternal vitamin D status and excessive fetal growth.

Methods In 2013–2014, pregnant women were recruited to the GraviD cohort study when registering at the antenatal clinics in south-west Sweden. In the present analysis, 1928 women were …

Implementing A Two-Tiered Model Of Optometry Training In Mozambique As An Eye Health Development Strategy, Diane Van Staden, James Loughman, Kovin Naidoo

Articles

Background: The global burden of vision impairment has been acknowledged by the World Health Organisation as a public health challenge. In order to scale up the production of eye health personnel in developing countries, a tiered model of optometry training was explored in Mozambique.

Exploring Subcellular Responses Of Prostate Cancer Cells To X-Ray Exposure By Raman Mapping, Maciej Roman, Agnieszka Panek, Hugh Byrne, Tomasz P Wrobel, Esen Efeoglu, Czeslawa Paluszkiewicz, Wojciech Maria Kwiatek

Articles

Understanding the response of cancer cells to ionising radiation is a crucial step in modern radiotherapy. Raman microspectroscopy, together with Partial Least Squares Regression (PLSR) analysis has been shown to be a powerful tool for monitoring biochemical changes of irradiated cells on the subcellular level. However, to date, the majority of Raman studies have been performed using a single spectrum per cell, giving a limited view of the total biochemical response of the cell. In the current study, Raman mapping of the whole cell area was undertaken to ensure a more comprehensive understanding of the changes induced by X-ray radiation. …

Multivariate Statistical Methodologies Used In In-Vitro Raman Spectroscopy: Simulations And Applications For Drug And Nanoparticle Interactions, Mark Edward Keating

Doctoral

Raman spectroscopy is a growing technology in the fields of in-vitro drug and nanoparticle screening. The label free capability provided by vibrational spectroscopy, as well as the ability of the technique to probe the chemical nature of samples, makes it a good candidate for use in these fields. Crucial to the progress of these methods is the development and validation of robust and accurate multivariate statistical analysis protocols. In this thesis, both established and novel methods are examined using both real and simulated datasets. In particular, simulated datasets are used to validate and assess the accuracy of these methods in …

Mutation Status In Myeloid Malignancies Informs Clinical Insight, Karl Haslam

Doctoral

The last decade has seen significant development in understanding the genetic basis of myeloproliferative neoplasms (MPN), with the underlying somatic mutational landscape revealed by genome and targeted exome sequencing. The aim of this research was to conduct a series of original investigations to develop insight into the utility and clinical application of these disease markers. Initially, three recently identified disease-specific molecular markers (mutations in JAK2, CALR and CSF3R) were utilised to measure the burden of disease post allogeneic transplantation using methods based on quantitative PCR, capillary electrophoresis and Sanger sequencing. The measured variant allelic frequency of the disease was compared …

The Use Of Fluid Haemodynamics In The Diagnosis Of Cardiovascular Disease, Andrew Malone

Doctoral

Currently the diagnostic methods used to detect cardiovascular disease largely rely on the inference of the presence of arterial stenosis. There is a clinical interest in the development of a diagnostic screening technique which can indicate the risk of developing cardiovascular disease at an early stage so that non-surgical treatments can be applied. The goal of this work was to develop and validate a diagnostic screening technique for cardiovascular disease using the mechanical biomarker wall shear stress. Improvements in wall shear stress measurements were made by using a 2D Fourier transform to extract additional spectral information from the ultrasound pulse …

Targeting Lipoprotein Biogenesis: Considerations Towards Antimicrobials, Toufic El Arnaout, Tewfic Soulimane

Articles

Decades have passed without approval of a new antibiotic class. Several companies have recently halted related discovery efforts because of multiple obstacles. One promising route under research is to target the lipoprotein maturation pathway in light of major recent findings and the virulence roles of lipoproteins. To support the future design of selective drugs, considerations and priority-setting are established for the main lipoprotein processing enzymes (Lgt, LspA, and Lnt) based on microbiology, biochemistry, structural biology, chemical design, and pharmacology. Although not all bacterial species will be similarly impacted by drug candidates, several advantages make LspA a top target to pursue …

Laser-Induced Breakdown Spectroscopy For Food Authentication, Maria Markiewicz-Keszycka, Raquel Cama-Moncunill, Maria Piedad Casado-Gavalda, Carl Sullivan, P. J. Cullen

Articles

With the globalisation of food markets, food authentication has become a significant concern worldwide to ensure food safety and to avoid origin and quality fraud. A multi-elemental fingerprint is a powerful tool for detection of adulterants and geographical origin of foods. Laser-induced breakdown spectroscopy (LIBS) is a promising technique that can provide a mineral fingerprint of food products. LIBS allows a rapid, high-throughput, micro-destructive and multi-elemental analysis of a wide range of samples type. It has already been demonstrated by several authors that LIBS can be successfully used for food authentication. Although LIBS shows excellent potential for at-line or portable …
