Exploring Race: The Collaborative Inquiry Experience of a Group of Black Social Work Faculty

Through a partnership presentation, presenters discussed the co-inquiry group process through which they explored their experiences as Black faculty who teach race based content in social work programs. They shared insights into what it means, what it takes, and what it costs to teach such content, and the benefits of the group process

Multipotency of Adult Hippocampal NSCs In Vivo Is Restricted by Drosha/NFIB

Adult neural stem cells (NSCs) are defined by their inherent capacity to self-renew and give rise to neurons, astrocytes, and oligodendrocytes. In vivo, however, hippocampal NSCs do not generate oligodendrocytes for reasons that have remained enigmatic. Here, we report that deletion of Drosha in adult dentate gyrus NSCs activates oligodendrogenesis and reduces neurogenesis at the expense of gliogenesis. We further find that Drosha directly targets NFIB to repress its expression independently of Dicer and microRNAs. Knockdown of NFIB in Drosha-deficient hippocampal NSCs restores neurogenesis, suggesting that the Drosha/NFIB mechanism robustly prevents oligodendrocyte fate acquisition in vivo. Taken together, our findings establish that adult hippocampal NSCs inherently possess multilineage potential but that Drosha functions as a molecular barrier preventing oligodendrogenesis

Jimmy Swaggart's Secular Confession

This is the author's accepted manuscript. The published version is available from http://dx.doi.org/10.1080/02773940902766748 .Following the exposure of televangelist Jimmy Swaggart’s illicit rendezvous with a New Orleans prostitute, the Assemblies of God simultaneously orchestrated a massive attempt to silence those who would discuss the tryst and arranged the most widely publicized confession in American history theretofore. The coincidence of a “silence campaign” with the vast distribution of a public confession invites us to reconsider the nature of the public confession. For what place has a public confession, the discourse of disclosure par excellence, in a silence campaign? This question is best answered, I argue, if we understand public confession not as a stable a-historical form, but as a practice that is informed by multiple, competing traditions. I argue that by situating Swaggart’s performance in a philosophically modern and secular tradition of public confession we can understand both its complicity in a silence campaign and, more generally, the political logic of the modern public confession

A randomized, double-blind, placebo-controlled trial of deprenyl and thioctic acid in human immunodeficiency virus-associated cognitive impairment

Cognitive impairment is a frequent manifestation of advanced human immunodeficiency virus (HIV) infection. The response to antiretroviral medication is often partial and poorly sustained. Recent studies suggest that free radical production within the CNS and neuronal apoptosis may play important roles in the pathogenesis of HIV dementia. We conducted a randomized double-blind, placebo-controlled trial using a parallel group, 2× 2 factorial design evaluating deprenyl, a monoamine oxidase B inhibitor and putative anti-apoptotic agent, and thioctic acid, an antioxidant, in 36 patients with HIV-associated cognitive impairment. Both deprenyl and thioctic acid were well tolerated with few adverse events. Deprenyl recipients showed significant improvement on tests of verbal memory compared with patients not taking deprenyl. Thioctic acid treatment did not improve cognitive function. These results suggest that deprenyl treatment is associated with cognitive improvement in subjects with mild HIV-associated cognitive impairment, whereas thioctic acid has no benefit. A larger efficacy trial is needed to assess the long-term effect of deprenyl on cognitive performance in patients with HIV infection. Human immunodeficiency virus type 1 (HIV-1)-associated dementia complex(HIV dementia) occurs in 15 to 20% of acquired immunodeficiency syndrome(AIDS) patients and is characterized by cognitive impairment, motor dysfunction, and behavioral changes.1-5 The cognitive impairment includes mental slowing, forgetfulness, and poor concentration. Motor symptoms include loss of fine motor control, clumsiness, unsteady gait, and tremor. Behavioral changes include apathy, lethargy, and depression.2,3,6 HIV dementia is usually a rapidly progressive disorder with a mean survival of about 6 months,2 although recently, patients with slower progression or a stable course have been identified.7 HIV-1-associated minor cognitive motor disorder, a milder syndrome, is estimated to occur in 25% of patients with symptomatic HIV infection.8 Few available antiretroviral agents have been studied for the treatment of HIV dementia. Open label studies with zidovudine (ZDV) in demented patients showed improvements in clinical functioning, neuropsychological performance, and neuroimaging studies.9 ZDV, in a placebo-controlled blinded study, also improved neuropsychological function in AIDS or AIDS-related complex patients without dementia.10 The only placebo-controlled trial of ZDV in HIV dementia demonstrated the greatest neurocognitive improvement only with very high dosages (i.e., 2,000 mg/day).11 Unfortunately, the response to ZDV treatment may be short-lived or associated with intolerable side effects and therefore often unsatisfactory. There is very limited information about the therapeutic effects of other antiretroviral medications (e.g., dideoxynucleosides)12 or protease inhibitors. Neurotoxins from HIV-infected activated macrophages or microglia interacting with astrocytes may play a central pathogenetic role in HIV dementia.13,14 Putative neurotoxins include cytokines (tumor necrosis factor alpha [TNF-α]) and oxygen radicals.2,15 Both TNF-α and hydroxyl free radicals may stimulate apoptosis (programmed cell death), and apoptotic neurons have been demonstrated in the cerebral cortex and basal ganglia of both children and adults with HIV encephalitis.16,17 We hypothesized that these indirect mechanisms of neuronal injury could be modified by deprenyl and thioctic acid to improve or even prevent HIV-associated cognitive impairment. Deprenyl, a selective monoamine oxidase type B inhibitor, at very low dosages in in vitro and in vivo systems has a trophic effect on injured neurons.18-21 Thioctic acid is a naturally occurring enzymatic cofactor for pyruvate dehydrogenase and alpha oxoglutarate dehydrogenase and scavenges harmful hydroxyl radicals and other reactive oxygen species.22,23 We conducted a randomized, double-blind, placebo-controlled clinical trial of deprenyl and thioctic acid to assess their safety and tolerability and to assess their impact on HIV-associated cognitive impairment in HIV seropositive (HIV+) patients

Clinical confirmation of the American Academy of Neurology algorithm for HIV-1-associated cognitive/motor disorder

Objective: Our goal was to put into operation the American Academy of Neurology (AAN) algorithm for the definition of minor cognitive/motor disorder and human immunodeficiency virus type 1 (HIV-1)-associated dementia complex (ADC) and examine the neuropsychological, neurologic, psychiatric, and functional deficits in affected subjects. Design: Two hundred seventy-one HIV-positive men and women with CD4 count of <200 or demonstrated cognitive impairment were recruited from three sites (Columbia University, The Johns Hopkins University, and the University of Rochester) and underwent standardized assessments. Results: Sixty-five subjects met criteria for ADC (cognitive, functional, and neurologic or behavioral), 56 met criteria for minor cognitive/motor disorder, and 150 met criteria for neither. Seventy-eight subjects met neuropsychological and neurologic/behavioral criteria but did not demonstrate functional impairment. Those with ADC performed significantly worse on speeded motor and verbal memory tests and demonstrated more extrapyramidal signs and behavioral symptoms than did the other two groups. Both ADC and minor cognitive/motor disorder were independently predictive of poor physical function, after adjustment for age, gender, years of education, log (CD4 count), hemoglobin, number of HIV diagnoses and medications, and depression. Conclusions: The operationalization of AAN criteria demonstrates that it is rare to have both cognitive and functional impairment without associated neurologic and/or behavioral deficits. Functional impairment in isolation is also rare. Dementia is an independent predictor of physical function. NEUROLOGY 1996;47: 1247-125
