Does relaying on rats testing proofs that the chemical BPA can cause human effect if yes or no how - Research Paper Example s who believe that rats do not share enough similarities with humans to provide proof of the effects that chemicals such as BPA will have on the human body. The following annotated bibliography explores the use of rats in testing with the endocrine disrupter BPA to show that rat testing can be useful in ascertaining the effects of chemicals on the human body. Ashby, J, and H Tinwell. ‘Uterotrophic Activity of Bisphenol A in the Immature Rat.’ Environmental Health Perspectives 106.11 (1998): 719–720. Print. This original research article explores the effects of BPA on the immature rat uterus. This study has been mentioned within a lot of the secondary sources within this bibliography, and therefore should be included. It was featured in a peer-reviewed journal, which means the results are reliable. It provides the evidence that BPA has a toxic effect on rats, although it does not illustrate whether this is useful when considering the human effect. Diel, Patrick et al. ‘Ability of Xeno- and Phytoestrogens to Modulate Expression of Estrogen-sensitive Genes in Rat Uterus: Estrogenicity Profiles and Uterotropic Activity’. The Journal of Steroid Biochemistry and Molecular Biology 73.1–2 (2000): 1–10. Web. 23 Feb. 2012. This original research article explores the effect of BPA and other xenoestrogens on the rat uterus. Like many of the other studies, it does not provide data from human studies for direct comparison, but conclusions are drawn, which suggests that the results are reliable enough for this journal. Many of the studies focus on the uterine effects, although there are effects on males as well as other physiological effects. Gupta, Ramesh C. Reproductive and Developmental Toxicology. Academic Press, 2011. Print. One of the most prominent effects that have been suggested by animal and human studies are developmental and reproductive. This book is an exploration of the toxic effects of many compounds on the reproductive and early developmental

Qualitative Article Critique - Essay Example In these cases asking patients about their symptoms is important, and the nurses must know what to ask for. This leads to both the problem and purpose of this study, where the nurses' perceptions about their abilities to assess and advise these patients are not known and hence need to be studied. This is a suffieciently narrow yet sigbificant problem in palliative care nursing where the disease needing palliative care has many problems per se, and depression is a common occurrence as an association that may be neglected easily. The population is thus about to die due to any cause where treatment fails, settiing become palliative care, and the variables become the nurses' perceptions about their knowledge and confidence about depression in these patients, and depressive symptoms. This also clarifoes the aim of the study which is to gather information about these variables. As evident, this problem is relevant to nursing care, since if they are proved to be having string perceptions ab out the depression and its effect on these patients, they can engage these patients into discussion about their depression, and that can be additional responsibility of these nurses while delivering palliative care. This study was very feasible in terms of money commitment and with certainty of availability of subjects in the palliatice care settings. This would not add to the extra cost since existing facilities and services would be used, and no extra equipment would be necessary. Ethically this was a sound hypothesis, and there are no reasons for it to be not ethically cleared by the appropriate authority. The authors are qualified and they are, although not categorically mentioned it seems, professors of university nursing schools. Literature Review 1.
