As bystander approaches become increasingly prevalent elements of sexual and domestic violence prevention efforts, it is necessary to better understand the factors that support or impede individuals in taking positive action in the face of aggressive or disrespectful behavior from others. This study presents descriptive findings about the bystander experiences of 27 men who recently became invo...

In this study, Chinese hamster ovary (CHO) cells were cultured in custom-made petri dishes with thin PADC films as substrates. Alpha particles with energies of 5 MeV were then irradiated from the bottom of PADC films. The DNA strand breaks in the bystander cells induced by irradiation were quantified with the use of terminal dUTP transferase-mediated nick end-labeling (TUNEL) assay. To study th...

Bystander intervention is a potentially potent tool in the primary prevention of sexual assault but more information is needed to guide prevention programs (Banyard 2008). Undergraduates (378 women and 210 men, primarily White) at a central coast California university completed an anonymous questionnaire measuring five barriers identified by the situational model of bystander intervention (Lata...

Gene directed enzyme prodrug therapy (GDEPT) of cancer aims to improve the selectivity of chemotherapy by gene transfer, thus enabling target cells to convert nontoxic prodrugs to cytotoxic drugs. A zone of cell kill around gene-modified cells due to transfer of toxic metabolites, known as the bystander effect, leads to tumour regression. Here we discuss the implications of either striving for ...

A SOCIAL COGNITIVE MODEL OF BYSTANDER BEHAVIOR AND THE MEDIATING ROLE OF SELF-EFFICACY ON BULLYING VICTIMIZATION by Samuel Yi Kim This dissertation introduces a social cognitive model of bystander behavior and examines the mediating role of self-efficacy on the relationship between bullying victimization and negative outcomes. Based on Bandura’s (1986; 2001) social cognitive theory, this model ...

OBJECTIVE Radiation effects induced in non-irradiated cells are termed radiation-induced bystander effects (RIBE). The present study intends to examine the RIBE response of QU-DB bystander cells to first, second and third radiation fractions and compare their cumulative outcome with an equal, single acute dose. MATERIALS AND METHODS This experimental study irradiated three groups of target ce...

Allergen Immunotherapy (AIT) is able to restore a physiological Th1 response and Tregs function. This effect is allergen-specific, even though it has been reported that it may also be non-specific, such as also extended to allergens not used in AIT. This immunological phenomenon may also be of clinical nature. This case report shows that a poly-allergic patient, successfully treated with Pariet...

We recently showed, using a parental double B16 melanoma tumor model that, in the presence of CENU-treated primary tumors, untreated secondary tumors exhibited growth inhibition. This response was shown to be related to CENU-induced bystander effects. To see whether CENU-induced bystander effects were still effective on non-parental syngeneic secondary tumors, Lewis lung (3LL) secondary tumors ...
