Crest cermony - Speech or Presentation Example day, I am a better person in claiming to be a stakeholder in the healthcare industry, thanks to the College of the North Atlantic – Qatar (CAN-Q) which helped me build the career and personality I most desired to have in life. It is for this reason that I find it a singular honour to be chosen to present this year’s CREST Ceremony to welcome you all into the institution. It is important that I first of all congratulate you for making it into CAN-Q and being accepted as students of the School of Health Science. Indeed your admission alone is an exemplification of your readiness to be part of a winning team, which CAN-Q has a trademark of being a champion in. There is a seed of championship in you all and so you should see yourselves as such. As the seed of championship has already been budded in you from the individual schools you are coming from, CAN-Q is going to serve as a very fertile farmland where the budded seed will be nurtured and fostered until it tussles, flowers and yields its fruits to be of profit to all humanity. This will be done with the help and assistance of the enabling learning environment which has been created in the institution for several years, making it part of the core traditions of CAN-Q. Please be assured that at CAN-Q, you will be offered student-centred and technology-rich teaching and learning experience. Indeed if I give all the pleasant comments and acknowledges about CAN-Q, I am not only doing so because protocol demands it. Rather, I am doing it because I am part of a living testimony of educational and professional transformation. I say so because when I first entered this institution, I had very little idea about how a single individual like me could transform the larger society. Little did I know that that potential was right inside me and that I only needed a little eye-opener from this prestige institution of which you have become part to make that ambition a reality. Today, I have a Bachelor with Honour in diagnostic

Roles of Estrogen in Development Essay Example | Topics and Well Written Essays - 1250 words

Roles of Estrogen in Development - Essay Example Most species with two sexes exhibit sexually dimorphic behavior and physical characteristics. New research suggests that the presence of estrogen, specifically estradiol, has an active role in sexual differentiation. Several sexual dimorphic structures in the brain have been observed in laboratory experiments. This study had been performed using male and female rats and had proved the differences in size of corpus callosum between two sexes had existed facilitated by estrogen. Estrogen plays an important role in male reproduction, critical for sustained fertility in some species. Reducing estrogen's interaction with its receptor(s) in monkey and mouse models is associated with reduced sperm motility and, in some cases, documented elimination of sperm fertilizing ability, suggesting that normal epididymal function may be estrogen dependent. The objective of the experiments was to evaluate the effects of reduced endogenous estrogen on development of epididymal function in the pig, a species in which males have very high levels of endogenous estrogen. Furthermore, reducing endogenous estrogen during postnatal development appears to have transient effects on porcine epididymal function. These transient effects suggest that the pig, with its high endogenous estrogen, may respond differently than other species to reduced estrogen synthesis (McCarthy, et al). This particular study provides a viable claim of estrogens importance on development of reproductive sys tem particularly in male specie. The development of the positive feedback of estrogen in normally fed animals and its possible alterations in animals subjected to restricted food intake has been the focus of another study and had indicated that the gonadotropin response to estrogen positive feedback develops gradually and quantitatively as the animal matures and undernutrition-induced delayed puberty is not caused by inability of the hypothalamic-pituitary unit to respond to positive estrogen feedback, but rather to ovarian failure to release estrogen in amounts sufficient to trigger a gonadotropin surge (Ronnekleiv, et al). Another study had determined whether endogenous estrogen, the levels of which increase with advancing pregnancy, regulates growth and development of the baboon fetal adrenal cortex. In the end it propose that estrogen acts directly on the fetal adrenal cortex to selectively repress the morphological and functional development of the fetal zone, potentially as a feedback system to maintain physio logical secretion of estrogen precursors and thus placental estrogen production to promote normal primate fetal and placental development (Albretch, et al). Despite the estrogens' significance on development, some studies apparently speak of its contribution to developmental errors. Evidences have accumulated that exposure to environmental components with estrogenic activity causes reproductive disorders in human populations. Studies conducted over the past 50 years have clearly shown a continual decline in semen quality accompanied by an increase in male reproductive disorders during this period in industrial countries. As healthy gametes are a prerequisite for healthy children, such disorders are a significant problem not only for the current society, but also for future generations. Epidemiological, clinical, and experimental studies have suggested that excessive exposure to estrogens and xenoestrogens during fetal and neonatal
