The role of nuclear medicine and other imaging modalities in Article - 1

The role of nuclear medicine and other imaging modalities in hyperthyrodism - Article Example In clinical practice different hyperthyroid conditions such as Graves’ disease, hyperthyroid goiter, and other conditions such as toxic multinodular or nodular goitre need assessment of activity of the gland. In this review, contemporary literature has been reviewed to update current knowledge on this topic. This assignment reveals that radionuclide imaging is an important diagnostic modality in the workup of hyperthyroid disorders, but despite that, in some cases the diagnostic yield is better with ultrasonography or PET scanning. In some cases, combined use of these imaging investigations pinpoints the diagnosis in a more suitable manner. Review of these articles and the knowledge apparent may be used to frame a guideline of advice regarding imaging practice in this area. The thyroid gland produces two hormones, namely, thyroxin (T4) and triiodothyronine (T3). These are known to play important physiological roles in the human body. Anatomically, the thyroid gland is located in the neck, in front of the trachea. It comprises of two lobes, right and left, connected by a narrow bridge of thyroid tissue, known as isthmus. It is a very highly vascular organ. The normal adult thyroid gland consists of follicles lined by thyroid follicular cells that contain large amount of thyroglobulin. This serves as the protein precursor of the thyroid hormones (Broome, 2006). Endocrinologically, increased need for thyroid hormone leads to a signal pathway mediated by thyroid stimulating hormone (TSH) leading to release of active hormone from a bound state with thyroglobulin to a free state, eventually being secreted into the blood stream. When there is hypersecretion of thyroid hormones due to any cause, the condition is known as hyperthyroidism. Usually hyperthyroidis m is indicated by an elevated level of TSH. Therefore, in clinical practice the diagnosis of hyperthyroidism is made by finding an abnormally elevated TSH level which

Corporate Social Responsibility and Disclosure Essay

Corporate Social Responsibility and Disclosure - Essay Example The abstract summarises in a very few words the contents of the paper. It is well written and divulges important and necessary information that is important from a reader’s perspective to decide whether the paper is of his/her interest or not. In the introduction, the author does a good job introducing the research topic and the reason behind choosing this topic. The introduction clearly states the purpose of the research. The research topic chosen by the author is important, mainly because of the target country/sample – Companies in Saudi Arabia. Going forward Saudi Arabia will not only play an important role in Middle East economy but also in world economy. It is one of the most important emerging markets globally and hence, the author’s topic is justified and relevant. The literature review lacks depth as it only lists the studies/research conducted on the topic and its results but fails to discuss in depth the importance of the findings of those researches. T he author has just touched upon each variable wherein in-depth discussion could have been very effective. The sample chosen and the methodology have been designed carefully by the researcher taking into consideration various factors and the population of the research. The author has explained the reasons behind the chosen research strategy. The researcher finds through this research that firm size significantly positively affects the level of disclosure while the other variables are insignificant. The researcher could have again in detail discussed the reason behind the role of different variables but instead only briefly discusses them. This leaves an opportunity for further research, to understand how and why the variables affect disclosure in companies. Article 2 - Contexts and corporate social responsibility: The case of Saudi Arabia The article looks at the different kinds of the CSR (Corporate Social Responsibility) related activities in Saudi Arabia.

The key drivers of the CSR (Corporate Social Responsibility) have been mentioned, but the exhaustive definition of each of the levels has not been provided. The weak points of the stakeholder have been mentioned. The characterization of these points is missing. The explanation also seems very theoretical, failing to explain the mechanisms behind it. Overall, the paper has been very well written; but
