A Meta-Analysis of Transcriptomic Footprints Disclose Specificity of Research Paper

A Meta-Analysis of Transcriptomic Footprints Disclose Specificity of Reactive Oxygen Species Signaling in Arabidopsis Study - Research Paper Example These species also have a signaling role and are very important in carrying out this signaling function, which is evident during various developmental processes such as allelopathic plant-plant interactions, cell elongation, and division, programmed cell death. It may also be noted during environmental processes as well as biotic and abiotic stress responses. Since a major part of metabolic activities are highly oxidizing, or have very intensive rates of electron flow; as a result, they tend to produce high levels of ROS. The signaling role is important because it produces the control and regulation of various biological processes and the ROS appear to have a dual role for these ROS in plant biology; both as the toxic by-products of aerobic metabolism as well as regulators of the various cell-based processes associated with growth, development as well as patterns of defense. Hence, at the outset, the significance of this study lies in the fact that the importance of reactive oxygen species has been identified, i.e., as a toxic byproduct of the biological processes which tends to function as a signal to regulate the various cell processes. Moreover, another aspect that could also be deduced in relation to this study and the findings of other researchers was outlined in the study that the ROS activity can lead to the oxidative destruction of cells. This is important because it shows that in so far as the evolution of aerobic organisms is concerned, the development of efficient ROS scavenging mechanisms is likely to be a causal factor in such evolution. The oxidative destruction of cells is caused by the partially reduced or activated derivatives of oxygen such as hydrogen peroxide and hydroxyl radical. The genome-wide microarrays provide the means to access the changes in transcripts arising out of an alternation in specific types of ROS. For example, whe n light stress occurs, there is an expression of heat shock proteins, which can be controlled by systolic H2O2.  

BHE 415 - Community and Domestic Violence (Module 3-SLP) Essay

BHE 415 - Community and Domestic Violence (Module 3-SLP) - Essay Example In addition, it contains factors that affect violence against women and the characteristics of victims and committers of violence. The rationale for choosing the topic of violence against women is that the violence that is done against women is far more critical and harmful than violence against men. Men as physically more powerful exercise their power over women without considering the aftereffects that women have to face. They do violence against women because they think that women are inferior to them and they have full right of assault against them. Many researchers have worked on this issue and recommendations are also given for the improvement of resolution of this problem. The topic of violence against women needs to be looked at in depth in order to find whether any prospective steps are taken for its solution or not and also to analyze the problems faced by women because of being victimized. Macmillan and Kruttschnitt (2005) report in their study, â€Å"Patterns of Violence against Women: Risk Factors and Consequences† that National Violence against Women Survey (NVAWS) conducted a telephone survey from November 1995 to May 1996, which included 8000 women and 8005 men. The survey took women into much consideration because of their being much affected because of violence. According to the report, women face higher risk of violence from their partners as all the violence strategies such as stalking, sexual assault, kicking, choking, beating, slapping, pushing, hair pulling, hitting with objects and threatening by weapons, all were in higher ratios from the male partners (Macmillan and Kruttschnitt, 2005). Watts and Zimmerman (2002) inform that the ratio of women victimization has increased not lessened. From 1993 to 1999, 21 % women (Switzerland, 1994-1996), 29 % women (Canada, 1993), 16 % women (Cambodia, 1996), 34 % (Egypt, 1995-1996), 33 % (Zimbabwe, 1996), 40 % (India, 1999), 35 % (New
