Impact of shear stress on vascular adaptations in humans. Large arteries are important for the delivery of blood and oxygen to organs such as the heart and brain. A primary physiological stimulus which controls the size and function of these crucial arteries is the magnitude of flow or, more accurately, shear force that the inner wall of the artery is exposed to. We have developed novel software which enables non-invasive assessment of arterial wall velocity, diameter and blood flow. We will ass ....Impact of shear stress on vascular adaptations in humans. Large arteries are important for the delivery of blood and oxygen to organs such as the heart and brain. A primary physiological stimulus which controls the size and function of these crucial arteries is the magnitude of flow or, more accurately, shear force that the inner wall of the artery is exposed to. We have developed novel software which enables non-invasive assessment of arterial wall velocity, diameter and blood flow. We will assess the impact of acute and chronic changes in wall flow and shear on arterial size and function. We will also develop new software which measures other aspects of artery wall behaviour. These basic human physiology studies have direct implications for assessment of artery health in humans.Read moreRead less
Masterminding Reproduction: Kisspeptin and RFamide-Related Peptide. There are a number of concerning trends in reproductive health. Women are reporting difficulty conceiving and maintaining pregnancies; while sperm count and quality are declining in men. More concerning is the increase in reproductive cancers. Gonadotropin-releasing hormone (GnRH) antagonist and agonist have been used for decades to treat reproductive cancers (such as breast cancer and prostate cancer), infertility and precociou ....Masterminding Reproduction: Kisspeptin and RFamide-Related Peptide. There are a number of concerning trends in reproductive health. Women are reporting difficulty conceiving and maintaining pregnancies; while sperm count and quality are declining in men. More concerning is the increase in reproductive cancers. Gonadotropin-releasing hormone (GnRH) antagonist and agonist have been used for decades to treat reproductive cancers (such as breast cancer and prostate cancer), infertility and precocious puberty. Kisspeptin and RF-related peptide may offer more physiological alternatives to GnRH, without detrimental side effects. We will fully explore these two newly defined and major players in reproduction and provide a physiological framework for their progression to clinical use.Read moreRead less
