ABSTRACT

Fundamental accounts in the Australian medical research reveal that around 60 percent of general populations use medical prescriptions with the number increasing to about 87 percent. Data collection performed on various individuals aged 65 years and over and 83 percent population over 85 years using various medications simultaneously. According to the research performed by 11 American surgical and medical units in a period of six months, rates of adverse drug events were 6.5 per every 100 admissions. The current medical reports assert that between two and three percent of all hospital admission in Australia may be medication related.

Pros and Cons of Genetically Modified Food

Along with the unprecedented scientific progress the humankind has achieved, new unexplored territories have been uncovered by researchers. Genetically modified foods, produced from crops grown from seeds with genetically engineered DNA, have been a hot topic throughout the past few decades (Gaskell et al., 1998; Marchant, 2001). The holders of the genetic information in every live organism, the genes, which are small fragments of the DNA chain, are intentionally manipulated to enhance the manifestation of some desirable traits, or to suppress the expression of other, unwanted features (e.g., genetic diseases).

Marijuana is among the most popular leisure drug in the World. Many people have smoked marijuana, and they do so despite the harsh laws placed against its use. It is non-toxic and cannot cause death. Significantly, it has a wide range of clinical uses such as relieving pain and nausea. In addition, marijuana is the appetite stimulating agent and less dangerous compared to alcohol and tobacco. Certainly, public policies should reflect this reality and legalize it.

Cardiac fibers contract through the process of excitation-contraction coupling which involve the conversion of an electrical stimulus to a mechanical response. In essence, contraction and relaxation help to regulate the flow of blood in the arteries, as well as the flow of the air through the lungs. Contraction involves a precise interaction of contractile proteins, calcium ions, and energy phosphates. Besides, the cardiac fibers relax to return the heart muscles after contraction to the initial conditions. Throughout life, cardiac cycle is significant as it enables the heart to contract 70 times per minute hence supplying five liters of blood to the body.
