Radiation-induced bystander fibroblasts both reduce and amplify micronuclei induction through the reciprocal bystander effect and the secondary bystander effect
… of radiation through cells also induces the bystander effect, which is the biological response of unirradiated cells that are neighboring or sharing medium with the irradiated cells. Although the mechanisms through which irradiated cells send signals to the bystander cells are not well …

Through the Eyes of a Bystander: Understanding VR and Video Effectiveness on Bystander Empathy, Presence, Behavior, and Attitude in Bullying Situations
… in bullying prevention campaigns is to call on bystanders in bullying situations to take responsible action. While many different forms of campaigns, including print and media campaigns, have aimed at trying to reduce the presence of bullying in schools by informing bystanders, there is still a …

Initiating a Bystander Awareness Program at a State University
… and potential attacks. This project initiates a bystander awareness program at a local state university, teaching students how to be effective bystanders. The objectives of this project was to increase knowledge about bystander awareness on a university campus and help students realize that a …

Bystander Behavior: Understanding Undergraduate Male Involvement in Dangerous Drinking Situations
… explores to what extent male college student bystanders involved in dangerous drinking situations intervene and to what extent information and training in specific bystander skills improves their likelihood to be effective, engaged bystanders. Many germane themes emerge in this study, …

A Single Campus Study of the Green Dot Bystander Intervention Program
… violence and how to prevent it by increasing bystander intervention. The current study examined the effectiveness of Green Dot at a large southeastern university. The Theory of Planned Behavior (TPB) was used as the theoretical framework. TPB examines how efficacy, attitudes, and norms …

Investigating the Dynamics of Bystander Behavior in Child Sexual Abuse Incidents
… This exploratory research examines what bystanders choose to do once they recognize that a minor may be in sexual jeopardy. Using a mixed methods approach involving survey research and case study analyses, this study measures the characteristics of bystanders, their attitudes toward …

Bystander influence of nematode exposure on subsequent herpesvirus infections in vivo
… Studies have shown helminth infections have bystander influences on unrelated conditions such as allergy and autoimmunity. Additionally, helminth infections can alter susceptibility to other infections. In this thesis, we investigate the systemic influences of murine nematode Nippostrongylus …

Do heavy ions induce the bystander effect? : study to determine the induction of the bystander effect from Fe ion beam compared to X-rays in human keratinocytes
The bystander effect is the observation that non-irradiated cells near a cell traversed by radiation express biological responses such as micronuclei formation and genomic instability. Most published studies of the bystander effect have been conducted using alpha particles, a high LET radiation. A …

Bystander-Effekt des Peroxynitrit und der toxische Effekt von Cu(II)-SOD
… Die Apoptoseinduktion durch ?NO und der Bystandereffekt sind vollständig SOD-blockierbar. <br>Der nicht-selektive apoptoseinduzierende Reiz des Wasserstoffperoxids wird durch Myeloperoxidase in den für transformierte Zellen spezifischen und selektiven Apoptoseinduktor HOCl umgewandelt. …

Space radiation-induced bystander signaling in 2D and 3D skin tissue models
… characteristic of this field suggest that bystander effects, the phenomenon in which a greater number of cells exhibit damage than expected based on the number of cells traversed by radiation, could be significant contributors to overall cell damage. The purpose of this thesis was to …

LET dependence of radiation-induced bystander effects using human prostate tumor cells
… This phenomenon has been coined as the "bystander effect". The purpose of this study was to characterize the ability of irradiated tumor cells to induce bystander effects in co-cultured cells. Human DU-145 prostate carcinoma cells were grown on a 1.4 [mu]m-thick mylar membrane in …

The role of nucleotides and the P2X7 receptor in radiation induced bystander effect
… related to radiotherapy is known as the bystander effect, whereby cells that have been irradiated initiate the destruction of neighbouring cells that have not been irradiated directly. The exact mechanisms that result in the bystander effect have yet to be fully identified. Purinergic …

Bystander stress: The effect of organizational tolerance of sexual harassment on victims' coworkers
… of the harassment of one's co-workers, the Bystander Stress scale. Job-related and psychological outcomes were measured, including satisfaction with co-workers, satisfaction with supervision, work withdrawal, life satisfaction, mental health, and symptoms of post-traumatic stress disorder. …

Attitudes, Identification, Decisions to Report, and Bystander Factors Among College Freshman Regarding Sexual Assault
… likelihood that students would intervene as a bystander, and demographics related to student attitudes toward, identification of, and decisions to report sexual assaults. Participants in this study were 551 freshmen in their first-semester at Temple University, who were 18 or 19 years of age. …

The role of stress-derived vesicles in the bystander effect and cancer related cachexia
… of EVs appears to be the induction of the bystander effect. The bystander effect refers to the non-targeted effects of stress, whereby stressed cells induce damage in neighbouring cells. EVs released from cells following irradiation have previously been shown to induce the bystander effect. …
