Essay 1. Immune Systems

There are two major groups of foreign substances and microscopic organisms that the immune system of the body could distinguished. The first group are the antigens that are freely moving around the body which includes viruses and foreign cells. The second group are the cells displaying aberrant major histocompatibility complex (MHC) proteins (Brito & Hinton, 1993). These cells includes self-cells which are invaded by the tumor cells and pathogens. In general, humoral immune response recognizes the antigens that are freely circulating around the body while the cell-mediated response recognizes the cells displaying aberrant MHC proteins (Rosenberg & Gallin, 1999).
The humoral Continue reading...

Introduction

Experimental and epidemiological researches have pointed that diet and environmental factors significantly determines the likelihood of tumors or human cancer. Even though the genetic history of people may influence the chance of neoplastic disease, it is still not the prevailing value in the preponderance of circumstances. Awareness has to be agreed to daily diet with chemo-preventive actions to diminish the risk of cancer. Studies have shown that alcohol consumption is associated with death from cancer. The relation of the risk to mortality reduces for moderate drinkers in contrast to nondrinkers and then amplifies with elevated alcohol drinking.

Social support from acquaintances encourages the growth of social bonds, which constrain the individuals from committing crime. The social bond theory proposed by Travis Hirschi states that delinquency occurs due to a person’s weak or broken bonds with the society, thereby minimizing the personal stakes in compliance. Individuals maintain compliance not in the fear of facing punishments, but in the fear of losing relationships with their friends, family and other social acquaintances . The inner containment of an individual plays an important role in establishing the relationship between delinquency and social bonds. Hirschi rejects to view the society as Continue reading...

Abstract

Radiation cataractogenesis (RCG) is deterministic. It does not occur below a minimum threshold dose. RCG is generally believed as dose-related. Sliney (1986) believed that its severity is also dose-related. The severity increased and the latency decreased as radiation dose increased above that threshold. The lens of the eye is nonvascular and is known to experience no cell loss over its lifetime, indicating that any damage to its cells will not result to the removal of these cells for lack of existing mechanism. Three induction mechanisms were explored (direct, indirect, and oxidative, which separately creates oxidative stress inside the lens Continue reading...
