Homeostasis is the process that controls certain things in the body such as body temperature (37oC) and water levels in order to ensure they say the same. It can also be described as maintenance of a constant internal environment. (GCSE Bitesize, OCR 21C Additional Science (Pre-2011), Homeostasis)   As well as temperature, homeostasis helps to …

Cardiovascular disease (CVD) is a class of diseases that include the heart or blood vessels. Cardiovascular disease includes coronary artery disease (CAD) such as angina  and myocardial infarction (commonly known as a heart attack).1 Cardiovascular diseases account for more deaths worldwide than any other disease. Together they resulted in 17.9 million deaths (32.1%) in 2015, up from 12.3 million (25.8%) in 1990.2 Overweight and …

Journal Discussion 1 Sigmund Freud (1856-1939):  “Freud was the Founding father of the psychodynamic approach” (Laura A. King, 2015). The most amazing contribution he made was to deeply discover one person’s unconscious level of their behavior or performance. It could analysis back to one’s childhood memories, dreams, feelings, and experiences. For me, the most attractive theory …

Lipid bilayer in cell separates the intracellular and extracellular cytoplasmic matrix, maintaining the structural integrity of the cell. It plays a vital role in exchange of substances between the cells and its environment, providing energy for the physiological processes. The major component of living organisms including all vertebrates, invertebrates, unicellular organisms and plants is water. …

ABI3 (Abscisic acid insensitive 3), a homologue of maize viviparous 1 (VP1), was identified in mutant background insensitive to ABA hormone. Earlier designated as a seed specific transcription factor 1-3, ABI3 has now emerged as a general regulator in cellular maturation and plant developmental processes such as quiescence of shoot apex meristem, plastid differentiation, regulation …

Melatonin is a hormone produced by the pineal gland. It is released into the body to signal rest and get ready for sleep when the eyes sense indication of darkness. It plays a significant role in regulating circadian rhythms (Soriento, 2010).              Cajochen, Frey, Anders, Späti, Bues, Pross, Mager, Wirz-Justice and Stefani (2011) studied the …

In a study done by Kempczinski in 1986, the flow effects on prostacyclin production by cultured human endothelial cells was examined. Endothelial cells line blood vessels and form blood tissue barriers (Kempczinski 1986). Shear stress can cause morphologic and cytoskeletal changes to cultured endothelial cells (Kempczinski 1986). These cells were chosen for this experimental model …
