Cellular and Molecular Biology concepts Speech or Presentation

Cellular and Molecular Biology concepts - Speech or Presentation Example Nucleus is one of the organelles found in the cell that is enclosed with a membrane. It is found in eukaryotic cells (Cech, 2000). Most of the genetic material of the cell is in the nucleus and this genetic material is organized in the form of long linear DNA molecules which are present in multiple numbers. The genetic material are present in complex associations with various proteins, known as histones to form chromosomes. Genes which are present within the chromosomes form the nuclear genome of the cell (Lamond, 1998). The main function of the nucleus is to maintain the integrity of the genes present in the chromosomes and regulate their expression. Thus, it can be said that the organelle, nucleus, is the control center of any cell. The nucleus is covered with a nuclear envelope which is basically a double membrane. The membrane separates the nucleus from other contents present in the cytoplasm. It contains some pores which host channels to facilitate movement of molecules and ions between the nucleus and the cytoplasm. The movement of these molecules is controlled carefully. For the purpose of movement of larger molecules, carriers proteins are present for active transport. The nucleus has a nuclear lamina within itself that provides mechanical support to the various contents of the nucleus.

Orem - Essay Example He also reports a consistent cold on his feet and a sore on his foot that has refused to heel, factors that forces him to wear protective socks. He further reports occasional passing out but maintains that he is fine. Mr. Fred’s significant problem that calls for healthcare attention is the ‘non healing sore on his foot.’ This is because even though the patient acknowledges presence of the sores, and the fact that the sores do not indicate a possibility of healing, Fred is still not willing to seek medication. The wound is not healing because of the patient’s high blood sugar level that facilitates growth of bacteria and it is enhanced by poor circulation. The most applicable theory to the case is the ‘Orem Self Care Deficit,’ theory that integrates â€Å"theory of self care, self care deficit theory, and theory of nursing systems† and seeks to empower patients to meet their healthcare needs with little or no assistance from healthcare personnel (Zaccagnini and White, p. 19; Kumar, p. 104- 106). The Orem theory is applicable to the case that identifies Mr. Fred’s ‘self-care’ deficiency, a factors that prolongs the wound (Nlm, p. 1). I would apply the theory by bridging the care gap to identify practices that would enhance the wound’s healing. I would use my skills as an educator to convince Fred of the need for medication and specialists advice on how to manage the wound. These would facilitate ‘self-efficiency’ and ‘self-reliance’ in his care initiatives (Nlm, p. 1). Application of the theory to the case is supported by existing literature that identifies its ability to promote ‘self-care’ among patients. Easom’s exploration of efficiency and its associated barriers among adult’s ‘self-care’ efforts for example identifies the need to break the barriers and promote self reliance as provided for by the theory, an approach that Fred really needs.
