Identifying and Preventing Arthropod Encounters in South-eastern USA Homes
Arthropods – which include insects, spiders, centipedes and woodlice – have inhabited this planet for millions of years. They are found in most habitats on Earth – including our gardens and homes. It is in these built environments that a small number are considered a nuisance. An even smaller number damage buildings or belongings, eat our food – even feed on us – so we label them… pests! Preventing pest infestations requires an understanding of their lifestyles and requirements for food, water, shelter, and favourable temperatures. This understanding is predicated on a proper identification.
Dr Catherine Richter | Exploring Enzymes in Fish to Accelerate Conservation
Thiamine – commonly known as Vitamin B1 – is required by almost all life on Earth. Humans and other animals need to consume sufficient amounts of this vitamin to support brain and heart health. Some organisms, including certain molluscs, fish and bacteria, contain thiamine-degrading enzymes known as thiaminases. As such, consuming these organisms can lead to thiamine-deficiency.
Dr Benjamin Scherlag | Could the Soul Be a Biophysical Reality?
Do human beings have a soul that leaves after they die? While all recognised religions suggest that they do, scientists have been unable to confirm this belief. The soul remains an elusive entity, which theoretically encompasses an individual’s personality and consciousness. Through scientific experiments, Benjamin Scherlag, Ronald Scherlag, Tarun Dasari and Sunny Po at the University of Oklahoma Health Science Centre recently investigated the soul. They carried out these experiments on a dwarf form of the organism Stentor coeruleus, which has regenerative abilities.
Dr David Ussery | Discovering New Groups of E. Coli Bacteria
Escherichia coli – more commonly known as E. coli – is a leading cause of diarrhoea-associated hospitalisation. However, E. coli does not always cause disease. Alongside thousands of other bacterial species, E. coli lives inside and on the surface of the human body. Numerous different strains of E. coli have been identified by analysing their genomes.
Dr Brian D. Tait | The Impact of Haplotyping on Disease Inheritance and Clinical Treatment
Humans inherit a version of each gene – an allele – from each parent. Through standard DNA analysis, it is not possible to know which allele of a given gene came from the mother and which came from the father. Understanding which allele came from which parent is known as ‘haplotyping’ or ‘genetic phasing’. This is particularly important when a gene has multiple changes in the gene sequence – called mutations.
Dr Youzhong Guo | Accelerating Our Understanding of Cell Membranes
Cell membranes are an essential constituent of all living organisms. They protect and organize cells, and perform a range of vital functions that ensure an organism’s survival. The two fundamental components of cell membranes are proteins and lipids, which form a diverse and complex system connecting the membrane to the wider cell. Interactions between cell-membrane proteins and between proteins and lipids play vital roles in myriad biological processes. Understanding these interactions is critical for identifying the mechanisms behind many medical disorders, in order to find ways of treating them. In-depth knowledge of these interactions is also crucial for drug design.
Professor Thomas Feuerstein | Using Mathematical Modelling to Understand Acute Heart Failure Treatment
Cardiovascular diseases are the most common cause of death around the globe. Heart failure is a particular type of cardiovascular disease, which occurs when the heart is not able to pump blood around the body as well as it should. Over 26 million people in the world are currently affected by heart failure and this number is increasing every year.
Dr Matthew Hoare | Understanding Gene Mutations in Chronic Liver Disease
The liver plays a vital role in keeping us healthy, by controlling levels of sugars and fats in our blood, as well as clearing the blood of toxins. Chronic liver disease affects around 25% of the population and is reported to be the third largest cause of premature death in the UK. Liver disease can occur as the result of long-term consumption of alcohol or viral hepatitis, but the fastest growing cause is non-alcoholic fatty liver disease, associated with obesity and type 2 diabetes.
Dr Peter Palese | Developing a Universal Flu Vaccine
The influenza virus – commonly known as flu – is a serious public health concern. There are an estimated 1 billion cases of influenza each year, causing approximately 650,000 deaths globally.
Dr John Fairbrother | Redefining High Risk Clones in Animal Populations
Antimicrobial drugs treat infections by killing or slowing the growth of the responsible pathogens. However, antimicrobial resistance occurs when the bacteria develop defence mechanisms against the very drugs intended to kill them. Infections due to resistant bacteria can be extremely difficult and even impossible to treat, meaning that antimicrobial resistance presents a major threat to animal, environmental and human health.
Taher Saif | Dr Andrew Holle – Mechanobiology – Exploring the Mechanics of Cell Behaviour
Extracellular biophysical cues have a profound influence on a wide range of cell behaviors, including growth, motility, differentiation, apoptosis, gene expression, adhesion, and signal transduction. Cells not only respond to definitively mechanical cues from the extracellular matrix (ECM) but can also sometimes alter the mechanical properties of the matrix and hence influence subsequent matrix-based cues in both physiological and pathological processes. Interactions between cells and materials in vitro can modify cell phenotype and ECM structure, whether intentionally or inadvertently. Interactions between cell and matrix mechanics in vivo are of particular importance in a wide variety of disorders, including cancer, central nervous system injury, fibrotic diseases, and myocardial infarction. Both the in vitro and in vivo effects of this coupling between mechanics and biology hold important implications for clinical applications.
Associate Professor Yukihiko Toquenaga | Sequencing the Genome: Two Heads are Better than One
The genome comprises the entire set of DNA instructions for each cell in all living things. DNA (deoxyribonucleic acid) is the hereditary material found in humans and other organisms. The genome contains all the information needed to build any individual living thing, and for it to grow and develop.
