Biomechanical and neurophysiological investigation of insect tympanal organs
… sound via the structure of their auditory organs could inspire new, more sensitive, acoustic sensor systems to be developed, where the insect hearing organs that have previously been documented are believed to be more sensitive than any man-made devices that can currently be made. Firstly …

Imaging innate immune cell behaviour in lymphoid organs
… for antigen presentation. Secondary lymphoid organs, including lymph nodes (LNs) and Peyer’s patches, are ideal sites for innate-adaptive cellular interactions. Whilst neutrophils migrate to LNs following inflammation, whether this occurs in homeostasis is unclear. I demonstrated the presence …

Electromagnetic pump and hardware development for organs-on-chips
MicroPhysiological Systems (MPS), also called organs-on-chips, attempt to mimic the relevant human multi-organ physiology in-vitro. They have potential applications in drug development and personalized medicine by enabling more accurate testing of physiological drug response earlier in the …

Intracellular and extracellular promoters of metastasis to different organs
Metastasis is the cause of the vast majority of cancer-related deaths, yet much remains unknown about this complex process, from how tumor cells complete the many steps of the metastatic cascade to how they can adapt to survive in multiple, vastly different secondary sites. I have therefore …

Oxygen Deficient Metabolism in Organs: A Link to Combustion Science
… suggest -1/3<bk<0 where bk=0 for small organs following isometric law and -1/3 for large organs while COA models suggest -2/3<bk<0 under similar conditions. Most experimental data for vital organs yield -0.27<bk<0 which suggests better correlation with COS models. B) Measured …

Gravimetric studies of certain Amphibian Organs under normal and experimental conditions
A cycle of seasonal ovarian weight changes in Xenopus is described, similar in all respects to that described by other workers.

Histological and morphological studies of the endocrine organs of xenopus laevis
… on record specifically and constitution of these organs in physiological operations.

What are southern Cape renosterveld geophytes storing in their underground organs?
… Africa, because they possess underground storage organs adapted to unpredictable climates. This study analysed the storage reserves of geophyte species from the southern Cape renosterveld, to determine if reserve concentrations varied with storage organ size and if different storage organ types …

Ultrastructure and functional morphology of adhesive organs and anti-adhesive plant surfaces
… surface structures and properties of adhesive organs and of slippery plant surfaces. In the first part of this study the morphology and ultra-structural setup of two different adhesive organs and of an anti-adhesive surface were characterised by using various microscopic techniques. Both …

Salinity Responsiveness of Aquaporins in Osmoregulatory Organs of Larval Mosquito Aedes Aegypti
… environmental salinity within the osmoregulatory organs. An entomoglyceroporin, AaAQP5, is the most abundant AaAQP expressed in the osmoregulatory organs with the most AaAQPs expression found in the Malpighian tubules and anal papillae when compared to other osmoregulatory organs assessed in this …

Organs and bodies : the Jew's harp and the anthropology of musical instruments
The Jew’s harp is unique among instruments, and in its apparent simplicity it is deceptive. It has been adapted to a wide array of cultural contexts worldwide and a diverse range of playing techniques, which, upon closer examination, reveal much about the cultures that generate them. Drawing on …

Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs
… on sternotomy wounds and on the intrathoracic organs. An uninfected porcine sternotomy wound model was used in all studies. The studies showed that negative pressure is transmitted only to tissues that are in direct contact with the foam dressing and not to deeper parts of the wound or thoracic …

Ethical issues relating to the 'donation' of human and animal organs for transplantation
… proposed ways of increasing the supply of organs for transplantation purposes. It starts from a consideration of two sorts of donors which are already in use: humans declared dead according to brain-based criteria and nonhuman animals. In the first chapter I attempt to provide a theoretical …
