Review of the History and Current Status of Cell-Transplant Approaches for the Management of Neuropathic Pain

Treatment of sensory neuropathies, whether inherited or caused by trauma, the progress of diabetes, or other disease states, are among the most difficult problems in modern clinical practice. Cell therapy to release antinociceptive agents near the injured spinal cord would be the logical next step in the development of treatment modalities. But few clinical trials, especially for chronic pain, have tested the transplant of cells or a cell line to treat human disease. The history of the research and development of useful cell-transplant-based approaches offers an understanding of the advantages and problems associated with these technologies, but as an adjuvant or replacement for current pharmacological treatments, cell therapy is a likely near future clinical tool for improved health care.

PROTEOMIC ANALYSIS OF WOLBACHIA SYMBIOSIS WITHIN THE DROSOPHILA OVARY

Wolbachia pipientis are bacterial endosymbionts carried by millions of invertebrate species, including ~40% of insect species and some filarial nematodes. In insects, basic Wolbachia research has potential applications in controlling vector borne disease. Conversely, Wolbachia of filarial nematodes are causative agents of neglected tropical diseases such as lymphatic filariasis and African river blindness. However, remarkably little is known about how Wolbachia interact with their hosts at the molecular level. Understanding this is important to inform the basis for symbiosis and help prevent human disease. I used a high-throughput proteomics approach to study how Drosophila host cells are modified by Wolbachia infection. This analysis identified 23 Drosophila proteins that significantly changed in amount as a result of Wolbachia infection. A subset of differentially abundant host proteins were consistent with Wolbachia-associated phenotypes reported previously. This study also provides the first ever discovery-based evidence for a Wolbachia-associated change in maternal germline histone loads, which has possible implications in Rescue of a common Wolbachia-induced reproductive manipulation known as Cytoplasmic Incompatibility.

Genital human papillomavirus: Women's knowledge and attitudes of this sexually transmitted disease

The purpose of this study was to investigate women's knowledge and attitudes regarding genital human papillomavirus (n=100). Using a descriptive design, the Health Education Questionnaire was administered to 100 female patients (Mean Age = 33, SD = 7.17) at a physicians office in South Florida. The results indicated a lack of knowledge regarding genital human papillomavirus with 21 patients (21%) reported having knowledge and 79 (79%) having never heard of this disease. In addition, the group familiar with genital human papillomavirus also possessed a low level of knowledge with only 57% acknowledging an association of genital human papillomavirus and cervical cancer, 52% aware that a pap smear can detect the virus, 42% knowing that antibiotics can not treat the disease and 57% aware that it is not associated with a family history. An association was found between attitudes and health seeking behaviors. Subjects stating that they would take all measures to prevent genital human papillomavirus, were more likely to have a pap smear within the last year (Chi-square (1) = 4.33, p < .05). Higher levels of education and income were associated with increased knowledge regarding genital human papillomavirus when subjects were categorized according to sociodemographic characteristic (Chi-square (1) =9.45, p < .05; Chi-square (1) = 6.75, p < .05). There was no significant correlation between knowledge and ethnicity, marital status or age. Findings indicated the need for improved education and promotion of positive attitudes regarding human papillomaviurs in order to improve health seeking behaviors among women.
