The contemporary world has seen the exponential rise of cancer prevalence in the aging population to somewhat alarming levels. This segment consists of individuals aged 65 years and above and is the fastest growing age group in the United States not only as absolute numbers of persons in the general population but also as a proportion of the total population. (Ershler & Longo, 1997). Recent statistics indicate that one in every eight people in America aged 65 years, and above develops cancer, with women accounting for 58% of all cancer cases (Browner, 2015). Since cancer risk increases with advancing age, ...

Introduction

Genetically-Modified Organisms as used in agriculture refers to any animals or plants that have been produced using techniques which alter the genetic material in a manner that is outside of natural recombination. Although GMOs have been in existence for many decades, both scientists and the public hold different views concerning their adoption. Today, there are many forms of GMO food products. The majority have one of several of their genes altered while in some instances a new plant is created. For example, the triticale a new plant created by crossing wheat and rye. The biggest driver and what gives ...

Recent statistics indicate that one in every eight people in America aged 65 years, and above develops cancer, with women accounting for 58% of all cancer cases (Browner, n.d.). Since cancer risk increases with advancing age, the elderly account for 56% and 70% of all new cancer diagnoses and mortalities in the country (Browner, n.d.). The cancer burden in ...

Introduction

Liver is an important organ in the digestive system. The selected infection is hepatitis C. This viral infection affects the liver and then results in the liver enlargement. This form of hepatitis is one of the major challenges worldwide since its discovery and this could be attributed to the absence of a vaccine against the viral infection. Another important contributory factor is that of the prolong period of inactivity of the virus within the host before clinical manifestation. These all contribute to the level of destruction of the liver caused by the virus.

Etiology

The main aetiology is by the hepatitis ...

The World Health Organization defines genetically modified foods (GMO) as “organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally”. It involves technology often referred to as gene technology, modern biotechnology or genetic engineering. The process allows for selective transfer of genes from one organism to another. The transfer of genes can be done between organisms of the same species or of different species. Genetic engineering has been practiced for many years. We often hear of cases where a specific gene is selected from an animal or plant and introduced into a different organism ...

According to Typep-1 Siegenthaler & Aeschlimann, (2007) the neme diabetes wass derived from a greek word, diabeinein which implies “to siphon”. There are two main types id diabetes (type 1, type 2) even though some researchers often contend that there is a third type called gestational diabetes. Ideally,type 1 diabetes is autoimmune conditions that occurs when the beta cells of the pancreas have been spifflicated (Siegenthaler & Aeschlimann, 2007; News medical, 2013). The leads to loss of glucose that becomes visible in the urine if it is above the renal threshold that is 190 to 200 mg/dl on average. This condition of ...

Introduction. Night blindness is one of the early warning signs of a deficiency in Vitamin A. Each year, between 250,000 and 500,000 children lose their sight because they do not consume enough Vitamin A, and half of those will die within twelve months of losing their sight. Also, many pregnant women in developing countries suffer from night blindness as a symptom of Vitamin A deficiency, a problem compounded by mortality during pregnancy and childbirth, as well as difficulties in birth and in performing lactation (Rahi, et al., 1995, p. 332). In addition to night blindness, Vitamin A deficiency can impair ...
