Context: To determine the prevalence of fathers' attendance at pretest cancer genetic counseling sessions with mothers undergoing BRCA1/2 genetic testing for hereditary breast/ovarian cancer (HBOC) risk, and to identify psychosocial and other correlates of fathers' attendance.", 'One hundred and twenty-one fathers of minor-age children who were spouses/partners of women (mothers) undergoing such counseling and testing were recruited, completed a behavioral self-report survey, and provided data about their sociodemographic backgrounds, father-child cancer communication histories, parenting relationship quality, and information-seeking and perceived knowledge.', 'A total of 27.3% of fathers attended pretest cancer genetic counseling with mothers. Compared to fathers who did not attend pretest cancer genetic counseling, those who did had stronger parenting alliances with mothers, were more likely to have sought out information about BRCA1/2 testing, and felt more informed about testing. In an adjusted logistic regression model of session attendance, the strength of the parenting alliance was associated with a 6% increase in the likelihood of attending genetic counseling (odds ratio [OR]=1.06, 95% confidence interval [CI]=1.01, 1.12, p<.05) and greater perceived knowledge about BRCA1/2 testing was associated with a four-fold increase in the likelihood of session attendance (OR=4.03, CI=1.77, 9.37, p<.001).
Answer: One in three fathers attend pretest cancer genetic counseling with mothers undergoing BRCA1/2 testing; those who do have closer parenting relationships and are more informed about BRCA1/2 testing.

Ex Output:
Does prevalence and correlate of mothers and fathers attending pretest cancer genetic counseling together?

Context: We hypothesized that atherosclerosis inhibits NO-mediated endothelium-dependent dilation of coronary arterioles through interaction of ox-LDL with its receptor, LOX-1, through the production of O2ÿ- in endothelial cells.', 'We assessed the role of ox-LDL in endothelial dysfunction in a murine model of atherosclerosis (ApoE KO mice). Coronary arterioles from WT control and ApoE KO mice were isolated and pressurized without flow. Although dilation of vessels to endothelium-independent vasodilator SNP was not altered between ApoE KO and WT mice, dilation to the endothelium-dependent agonist, ACh was reduced in ApoE KO versus WT mice. Impaired vasodilation to ACh in ApoE KO mice is partially restored by NAD(P)H oxidase inhibitor, apocynin or DPI. Messenger RNA expression for NAD(P)H oxidases was higher in ApoE KO mice than that in WT and anti-LOX-1 treated ApoE KO mice. Anti-LOX-1, given in vivo, restored NO-mediated coronary arteriolar dilation in ApoE KO mice, but did not affect the endothelium-dependent vasodilation in controls.
Answer: These results suggest that ox-LDL impairs endothelium-dependent NO-mediated dilation of coronary arterioles by activation of a signaling cascade involving LOX-1 and NAD(P)H oxidase expression.

Does anti-LOX-1 rescue endothelial function in coronary arterioles in atherosclerotic ApoE knockout mice?

Context: Electroporation has been shown to increase the efficacy of intramuscular injection of plasmid DNA, resulting in a higher level of foreign gene expression. Using this technique, we examined the effect of viral IL-10 gene transfer on the prevention of tracheal allograft stenosis in an animal model.', 'On the day of tracheal transplantation, recipient Lewis rats were intramuscularly injected with either plasmid pCAGGS-LacZ or plasmid pCAGGS-viral IL-10, followed immediately by electroporation. Tracheas from Brown Norway donors were transplanted into the backs of Lewis recipients, and the histology of the grafts were assessed 2 and 4 weeks after transplantation.', 'The serum level of IL-10 peaked at 2000 pg/ml one day after injection; the level then slowly decreased, but was maintained above 1000 pg/ml until 8 days after injection. At Day 28, the airway lumina of the tracheal allografts were almost completely obliterated by fibroproliferative tissue in the control pCAGGS-LacZ-treated rats. In rats injected once with pCAGGS-viral IL-10, luminal obliteration was significantly decreased compared with the control pCAGGS-LacZ-treated rats (mean luminal opening 46.8% vs 0% p<0.05). The loss of epithelial cells lining the airway was also decreased in the IL-10-treated group (mean epithelial coverage 42% vs 5% p<0.05). Multiple injections with pCAGGS-viral IL-10 did not further improve the histological changes.
Answer: IL-10 gene transfer by intramuscular injection using electroporation attenuated tracheal allograft stenosis associated with mild epithelial injury.
