An Account of the Anatomy and Physiology of Congenital Heart essays

An Account of the Anatomy and Physiology of Congenital Heart essays Congenital heart disease (or CHD) is a range of heart disorders, of varying degrees of severity, which are present at birth. CHD affects about eight in every one thousand live babies that are born and is caused by factors operating early in pregnancy. These factors include viral infections (e.g. Rubella), diabetes, maternal radiation and drugs (such as thalidomide, warfarin and phenytoin). CHD is also a feature of Downs syndrome (approximately 30% of sufferers have CHD) and other chromosomal defects. The diseases include the hole in the heart (septal defects), patent ductus arteriosus, pulmonary stenosis (valve narrowing), aortic stenosis and fallots tetralogy. In the developing embryo, two endothelial tubes run in the belly and fuse in the neck region to form the single heart tube. Venous inflow and arterial outflow are at the caudal (tail) and cephalic (head) ends of the heart tube, respectively. The tube is divided into five segments: sinus venosus, atrium, ventricular inlet component, ventricular outlet component and arterial segment. During the fourth week of gestation, complex looping of the heart tube provides the basis of adult cardiac structure, with the ventricle lying beneath the atrium. The four-chambered structure requires separation of the atrial and ventricular components (and also the division of the arterial segment into the aorta and pulmonary artery). These separations occur during the fifth and sixth weeks of gestation and it is this process which is most prone to erroneous development. By the end of the eighth week, cardiovascular development is complete and no further changes take place until birth. CHD offers many clinical manifestations, heart failure being the most obvious. If this occurs in the neonatal period/ first month of independent life, it presents a medical emergency and may be caused by almost any major cardiac defect. In the preterm baby, heart failure is usually the res...

Top university rankings

Top university rankings University Oxford Tops Top places institutions struggle to obtain the highest places in the world scale rankings, since having all possible awards and honors; they struggle for the world’s recognition. It is something like sport race in academic circles. Having established huge research base and lecturing staff these educational giants compete in the quantity of trans-border students, researches and international prospect. There are the queues of students, who want to enter universities with the position in the top possible ranking and only the best of the best achieve this. Lucky owners of diplomas from these universities have all doors to successful carrier open before them. For the last five years California Institute of Technology occupied the leading place in regard to Times Higher Education table of the best universities. This year Oxford took the first place and made California Technology Institute to be put to a lower position (2nd place). New view on the British education Since the European Union membership referendum of the United Kingdom of 2016 there appeared a threat that it would reflect the attitude of many countries in regard to many spheres of the UK. And this point also has to do with education, as now the treatment of the UK education and its institutions by the international students can greatly change. The referendum seemingly already disturbs some incertitude in this sector and new changes appear in it. For example, the ability for some researchers and lecturers to cooperate with other European scientists underwent some shifts. Now it is not so easy for them to lead the mutual work in many educational aspects and scientific researches. The possibility to carry out some international education conferences and symposiums between the British institutions and those, which are located in other states in Europe is significantly lower, that before. Of course, as of now, this point is not of a great concern, but nevertheless, it visibly brought new issues and troubles. This year the British are the best The results shown this year in regard to the best institutions board of the Times Higher Education of world-wide leaderboard of universities undoubtedly make the United Kingdom proud. Oxford University, the oldest in regard to the English speaking world, became the first in the world ranking, leaving behind other institutions, and in particular, California Institute of Technology, which was the 1st past year. It should be noted that this year’s rankings results also showed the streaming moving up of Asian universities, coming to 25 best in the world. This means that institutions of the US and those in Europe, which so long possessed the superiority in regard to education, gave way to Asian universities concerning some points. These shifts cannot leave indifferent even the biggest skeptics, which prove that new times sometimes bring unexpected and unpredictable things. Oxford is the leader University of Oxford is known to be the university with the richest far-back history in English speaking world that was founded in about 1096 and since then remained one of the best institutions worldwide in all times. Thousands of trans-border multicountry students come to it for one of the best possible educations on the globe each year. Placed always in the top 10 universities in the world scale, it proved to provide the front-rank education, study conditions, scientific researches etc. at any time. In 2017 Oxford is the first in line worldwide not only in the Times Higher Education World University Rankings, but also in the Forbes's World University Rankings. Oxford was also recognized as one of the world’s â€Å"six super brands† in regard to World Reputation Rankings. And concerning the World University Rankings (QS) in relation to Subject, Oxford University obtained the first position in the list in relation to the Humanities disciplines, such as English Language and Literature, History and Geography. It can be stated that, no matter what time is nearby and what attitudes the world’s society can have, the rooted traditions prove to be the best. This is what can be said of the University of Oxford – the one that was always the leader and remains the one, no matter what.
