Correlates of HIV testing among abused women in South Africa.

Gender-based violence increases a woman's risk for HIV but little is known about her decision to get tested. We interviewed 97 women seeking abuse-related services from a nongovernmental organization (NGO) in Johannesburg, South Africa. Forty-six women (47%) had been tested for HIV. Caring for children (odds ratio [OR] = 0.27, 95% confidence interval [CI] = [0.07, 1.00]) and conversing with partner about HIV (OR = 0.13, 95% CI = [0.02, 0.85]) decreased odds of testing. Stronger risk-reduction intentions (OR = 1.27, 95% CI = [1.01, 1.60]) and seeking help from police (OR = 5.51, 95% CI = [1.18, 25.76]) increased odds of testing. Providing safe access to integrated services and testing may increase testing in this population. Infection with HIV is highly prevalent in South Africa where an estimated 16.2% of adults between the ages of 15 and 49 have the virus. The necessary first step to stemming the spread of HIV and receiving life-saving treatment is learning one's HIV serostatus through testing. Many factors may contribute to someone's risk of HIV infection and many barriers may prevent testing. One factor that does both is gender-based violence.

Copper signaling axis as a target for prostate cancer therapeutics.

Previously published reports indicate that serum copper levels are elevated in patients with prostate cancer and that increased copper uptake can be used as a means to image prostate tumors. It is unclear, however, to what extent copper is required for prostate cancer cell function as we observed only modest effects of chelation strategies on the growth of these cells in vitro. With the goal of exploiting prostate cancer cell proclivity for copper uptake, we developed a "conditional lethal" screen to identify compounds whose cytotoxic actions were manifested in a copper-dependent manner. Emerging from this screen was a series of dithiocarbamates, which, when complexed with copper, induced reactive oxygen species-dependent apoptosis of malignant, but not normal, prostate cells. One of the dithiocarbamates identified, disulfiram (DSF), is an FDA-approved drug that has previously yielded disappointing results in clinical trials in patients with recurrent prostate cancer. Similarly, in our studies, DSF alone had a minimal effect on the growth of prostate cancer tumors when propagated as xenografts. However, when DSF was coadministered with copper, a very dramatic inhibition of tumor growth in models of hormone-sensitive and of castrate-resistant disease was observed. Furthermore, we determined that prostate cancer cells express high levels of CTR1, the primary copper transporter, and additional chaperones that are required to maintain intracellular copper homeostasis. The expression levels of most of these proteins are increased further upon treatment of androgen receptor (AR)-positive prostate cancer cell lines with androgens. Not surprisingly, robust CTR1-dependent uptake of copper into prostate cancer cells was observed, an activity that was accentuated by activation of AR. Given these data linking AR to intracellular copper uptake, we believe that dithiocarbamate/copper complexes are likely to be effective for the treatment of patients with prostate cancer whose disease is resistant to classical androgen ablation therapies.

Virgin Territory: Theology, Purity, and the Rise of the Global Sex Trade

Sex sells. A lot. But who exactly is on the market?

What kinds of bodies are calibrated for traffic and consumption, and how exactly do they get there? When it comes to “sex” trafficking—which comprises a minority percentage of human trafficking, yet dominates the moral imagination as an “especially heinous” crime—the rise in predominantly white, evangelical Christian American interest in the trafficked subject galvanizes an ethical outrage that rarely observes critiques of race, ethnicity, sexuality or class as conditions of possibility. Though a nuanced mandate to fight trafficking is all but cemented in the contemporary American political and moral conscience, Virgin Territory accounts for the ways Christian ideas of purity annex both gender and sexuality inside the legacies of racialized colonial encounter, and foreground the market expansion of the global sex trade as it exists today.

In Part I, I argue that the narratives of virginity tied to Mary’s body simultaneously foregrounded the gendered, sexed Other as sparked disdain for the religious Other, for the Jewish body and for Mary’s Jewish identity. Through this analysis I explore the connections of racial identity to the Christian theological elision of Jewish election. I demonstrate how the questions of sexual ethics materialized at the site of the Virgin Mary, and align the moral attachments of sex and purity in the production of whiteness. These machinations, tied to the emerging European identity of empire, irrupt horrifically into the narrative ontology of dark flesh in Africa, Asia, and the Americas.

In Part II, I highlight the function of these narratives inside of the moments of colonial encounter, demonstrating how the logics of purity and virginity were directly applied to manage dark female flesh. I map the visual iconography of the Black Madonna first through a Dutch painting entitled The Rape of the Negress. I read this image through the social theological imagination instantiating the idea of the reprobate body and white imperial gaze. This analysis foregrounds a theological reading of Sarah Baartman, the “Hottentot Venus,” as the center of a complex sex trafficking investigation, outlining the genealogy of race, as well as the ideologies of the racial, ethnic and national Other, as mitigating factors in the conditions of possibility of a global sex trade. By restoring these narratives and their theological undertones, I reiterate the ways Christian thought is imbricated in the global sex trade, and propose theological strategies for rethinking humanitarian responses to sex trafficking.
