Discussion In nature, there are a group of proteins which are known to produce a universal response that is the production of stress proteins namely heat shock proteins (Hsp70), expressed in response to external stimuli. They are expressed in normal state conditions hence aiding in the native polypeptides folding and its translocation to different cellular compartments (Feder and Hofmann, 1999; Hartl and Hartl-Meyer, 2002). Iwama et al. (2004) worked on whether Hsp70 are a molecular marker for indicating stressed states in fishes. Ammonia which is a common pollutant has been seen and known to interfere with cellular proteins and in turn interfere with amino acid homeostasis (Cooper and Plum, 1987). As a result of ammonia toxicity, Hsp70 protein gets enhanced and in turn helps in inducing proteotoxicity. Our observation proves that the ability of these fishes (M. cuchia) to tolerate such high concentration of NH4Cl is mainly due to the ability of Hsp70 to induce proteotoxicity, an ability to rep air partly denatured proteins caused due to ammonia toxicity. Similar observation of expression of Hsp70 was seen in brown trout (Salmo trutta f. fario) exposed to sub-lethal concentrations of ammonia (Luckenbach et al., 2003). Immunocytochemical analysis clearly demonstrated the localized expression of Hsp70 in liver, kidney and brain of M. cuchia during exposure to 50 mM NH4Cl for 7 days with a slight fall of expression in 14 days 50 mM NH4Cl tissues (Fig. X). Immunopositivity to Hsp70 antibody has been detected in control as well as in 7 and 14 days 50mM NH4Cl treated tissues. In the unstressed cells Hsp70 helps in maintaining cellular homeostasis (Fink and Goto, 1998). In liver, the expression of Hsp70 was more predominant in hepatic sin... ...l red skeletal muscle of paddleï ¬ sh. To add to our observation, Poltronieri et al. (2008) also found Hsp70 immunonegativity in control tissues of carp (Cyprinus carpio) and rainbow trout (Oncorhynchus mykiss) along with absence of immunopositivity in stressed states. The fall in immunoreactivity which was observed in 14 days of NH4Cl treated tissue might be mainly due to slight acclimatization at the end. Therefore, one needs to find out the possible implications of Hsp70 in this fish, M. cuchia, which is known to tolerate high ammonia concentrations. As Hsp70 is known to act as an important candidate for identification of stresses and also an important biomolecules acting as sentinels of contamination exposure, this stress proteins, Hsp70 might give a better understanding of how these fishes adapt themselves to such concentrations of environmental ammonia toxicity.

Essay on Homelessness A National Epidemic - 1305 Words
In our nation today, we the citizens of the United States of America have been pummeled with rising economic and social problems. Homelessness is one of the major issues that derived centuries ago, and is still in effect today.

Even though it is not required but there is no harm in doing something good for others. A large number of homeless people did not intentionally put themselves in the position that eventually led into homelessness; some were evicted from their homes, or they were mentally and physically sick and unable to hold employment to provide for themselves. In tThe article, â€Å"Homeless Research, Services and Social Policy†described many causes of how people become homeless. It states in the article that the common factors that lead to homelessness are health, social, economic, and housing issues (1). It also states that a vast number of homeless people are women and children (1). In other cases people who are homeless it is simply their own fault. They make an unwise decision which causes them to suffer the consequences of abandonment or end up in the penitentiary. These types of people are either strung out on drugs, addicted to alcohol, or simply just gave up on themselves. Another issue that leads people displaced is the overuse of drugs, and alcohol, and mental disorders (2).
