Citation analysis of faculty publication: beyond Science Citation Index and Social Science Citation Index.

When evaluated for promotion or tenure, faculty members are increasingly judged more on the quality than on the quantity of their scholarly publications. As a result, they want help from librarians in locating all citations to their published works for documentation in their curriculum vitae. Citation analysis using Science Citation Index and Social Science Citation Index provides a logical starting point in measuring quality, but the limitations of these sources leave a void in coverage of citations to an author's work. This article discusses alternative and additional methods of locating citations to published works.

Alternative carbon metabolism: Virulence and regulation in Candida albicans

The interaction between C. albicans and innate immune cells is a key determinant to disease progression. Transcriptional profiling showed that C. albicans responds to macrophage phagocytosis by inducing pathways required for alternative carbon metabolism (beta-oxidation, the glyoxylate cycle, and gluconeogenesis), suggesting these pathways are important for virulence of C. albicans. ^ We have shown that deleting key genes (FOX2, FBP1) in these pathways results in virulence defects in an in vivo mouse model for systemic infection. Like icl1Δ/Δ mutants, fbp1Δ/Δ mutants are severely attenuated and fox2Δ/Δ mutants are mildly but significantly attenuated, indicating that carbon starvation is a relevant stress in vivo. ^ However, fox2Δ/Δ mutants also had unexpected phenotypes on certain carbon sources, unlike the case in Saccharomyces cerevisiae, suggesting these pathways are regulated differently in C. albicans. To test this, we identified the C. albicans regulators of these pathways based on those from S. cerevisiae and Aspergillus nidulans. ^ C. albicans has a partly conserved framework, but lacks two regulators (Oaf1p, Pip2p) controlling peroxisome biogenesis and beta-oxidation genes in yeast. Instead, C. albicans has a homolog, CTF1, of the A. nidulans fatty acid catabolism regulators FarA and FarB. We have shown that CTF1 is needed for growth on oleate (like FarA and FarB), expression of beta-oxidation and glyoxylate cycle genes, and full virulence. No function for CTF1 has previously been identified in C. albicans. Our data demonstrate a role for alternative carbon metabolism in the virulence of C. albicans and suggest that the regulation of these pathways is a mixture of the filamentous fungi and budding yeast systems. ^

Evaluating alternative therapies. Support/imagery and immune function in breast cancer: A pilot study

Cancer patients increasingly request alternative therapies such as imagery techniques and support groups. Although research suggests evidence of enhanced psychosocial functioning with supportive group therapy and enhanced immune function with imagery techniques, studies are anecdotal or limited to case studies or descriptive reports. The efficacy of these alternative therapies should be validated by randomized, controlled trials and the mechanisms of action mediating immune function and outcome examined.^ In a 12-month pilot study, we evaluate the feasibility of conducting a controlled study with clinical trial methodology to test the effects of imagery/relaxation and support on quality of life, emotional well-being, and immune function for women after breast cancer. Using a randomized pre-post test design with three intervention waves, we assigned women (n = 47) to either standard care (n = 15), standard care plus 6-weekly support sessions (n = 16) or imagery/relaxation sessions (n = 16).^ The primary aim of this pilot study is to determine the feasibility of conducting a clinical trial of alternative therapies in a clinical care setting. Secondary aims are to determine parameter estimates for the effects of the two treatment groups on quality of life, coping, social support, and immune function and describe methodology issues related to trials of alternative therapies.^ The research provides direction for future studies of alternative therapies by describing the recruitment, clinical trial experience, and related methodology issues. The study extends previous work by differentiating the effects of support group from mental imagery among outpatient groups who are homogeneous regarding cancer type and treatment stage. The study provides data for future longitudinal studies of disease progression by differentiating the effectiveness of interventions designed to enhance quality of life, coping, social support, and immune function and subsequently, alter the clinical course of disease. ^
