Abstract
Few data exist on oral human papillomavirus (HPV) prevalence in female sex workers (FSWs). Information regarding oral sex practices of 185 Peruvian FSWs, 18-26 years of age, was obtained via survey and compared with HPV testing results of oral rinse samples. Oral HPV prevalence was 14/185 (7.6%); four (28.9%) HPV genotypes were carcinogenic. One hundred and eighty-two participants reported having had oral sex; 95% reported condom use during oral sex with clients and 9.5% with partners. Women who had oral sex more than three times with their partners in the past month were more likely to have oral HPV than women who had oral sex three times or less (P = 0.06). Ten (71.4%) women with oral HPV were HPV-positive at the cervix; conversely 8.3% of women with cervical HPV were HPV-positive in the oral cavity. The prevalence of oral HPV was relatively low, considering the high rates of oral sex practiced by these women.

Abstract
OBJECTIVES To investigate whether gene nutrient interactions influence the risk of cognitive dysfunction among older persons. DESIGN We performed a cross-sectional and longitudinal study of 499 adults aged 70-79 years from the Mac Arthur Study of Successful Aging to determine the effect of apolipoprotein E (APOE) in conjunction with plasma levels of homocysteine and of the related B vitamins on multiple domains of cognitive function and cognitive decline. RESULTS The APOE-ε4 allele, high homocysteine, low folate, and low vitamin B6 levels were each associated with worse baseline cognitive function, and all but B6 and B12 were associated with seven year cognitive decline. There was no interaction between APOE-ε4, and homocysteine, folate, B6, or B12 in predicting baseline cognitive function (p-values: 0.12-0.94) or longitudinal decline (p-values: 0.52-0.91). Of five cognitive subtests, there was a significant interaction between the ε4 allele, low B6, and decline in correct naming response items (p=0.04). CONCLUSION B vitamin status does not influence the risk of overall cognitive dysfunction in ε4 allele affected older adults.

Abstract
OBJECTIVES To implement and assess the effectiveness of a program to teach pharmacy students the importance of taking personal responsibility for their health. DESIGN The My First Patient Program was created and lectures were incorporated into an existing first-year course to introduce the concepts of health beliefs, behavior modification, stress management, substance abuse, and nutrition. Each student received a comprehensive health screening and health risk assessment which they used to develop a personal health portfolio and identify strategies to attain and/or maintain their personal health goals. ASSESSMENT Student learning was assessed through written assignments and student reflections, follow-up surveys, and course evaluations. Students' attainment of health goals and their ability to identify their personal health status illustrated the positive impact of the program. CONCLUSION This program serves as a model for colleges and schools of pharmacy and for other health professions in the instruction of health promotion, disease prevention, and behavior modification.

Abstract
OBJECTIVES A population-based sexual network study was used to identify sexual network structures associated with sexually transmitted infection (STI) risk, and to evaluate the degree to which the use of network-level data furthers the understanding of STI risk. METHODS Participants (n = 655) were from the baseline and 12-month follow-up waves of a 2001-2 population-based longitudinal study of sexual networks among urban African-American adolescents. Sexual network position was characterised as the interaction between degree (number of partners) and two-reach centrality (number of partners' partners), resulting in the following five positions: confirmed dyad, unconfirmed dyad, periphery of non-dyadic component, centre of star-like component and interior of non-star component. STI risk was measured as laboratory-confirmed infection with gonorrhoea and/or chlamydia. RESULTS Results of logistic regression models with generalised estimating equations showed that being in the centre of a sexual network component increased the odds of infection at least sixfold compared with being in a confirmed dyad. Individuals on the periphery of non-dyadic components were nearly five times more likely to be infected than individuals in confirmed dyads, despite having only one partner. Measuring network position using only individual-based information led to twofold underestimates of the associations between STI risk and network position. CONCLUSIONS These results demonstrate the importance of measuring sexual network structure using network data to fully capture the probability of exposure to an infected partner.

Abstract
To perform whole genome scanning for complex trait analysis, we isolated and characterized a total of 21 novel genomic-SSRs and EST-SSRs for yellow perch (Perca flavescens), using the methods of construction of SSR-enrichment libraries and EST database mining of a related species P. fluviatilis. Of 16 genomic-SSR primer pairs examined, eight successfully amplified scorable products. The number of alleles at these informative loci varied from 3 – 14 with an average of 8.5 alleles per locus. When tested on wild perch from a population in Pennsylvania, observed and expected heterozygosities ranged from 0.07 – 0.81 and from 0.37 – 0.95, respectively. Of 2,226 EST sequences examined, only 110 (4.93%) contained microsatellites and for those, 13 markers were tested, 12 of which exhibited polymorphism. Compared with genomic-SSRs, EST-SSRs exhibited a lower level of genetic variability with the number of alleles of averaging only 2.6 alleles per locus. Cross-species utility indicated that three of the genomic-SSRs and eight of the EST-SSRs successfully cross-amplified in a related species, the walleye (Sander vitreus).

Abstract
11q13 amplification is a late-stage event in several cancers that is often associated with poor prognosis. Among 11q13-amplified genes, the actin assembly protein cortactin/CTTN is considered a likely candidate for direct involvement in tumor progression, because of its cell motility-enhancing functions. We modulated cortactin expression in head and neck squamous cell carcinoma (HNSCC) lines. Cortactin expression levels directly correlated with tumor size, vascularization, and cell proliferation in an orthotopic HNSCC in vivo model. In contrast, under normal in vitro culture conditions, cortactin expression levels had no effect on cell proliferation. However, cell lines in which cortactin expression was reduced by knockdown (KD) grew poorly in vitro under harsh conditions of growth-factor deprivation, anchorage independence, and space constraint. Conversely, overexpression of cortactin enhanced in vitro growth under the same harsh conditions. Surprisingly, defects in growth factor-independent proliferation of cortactin-KD cells were rescued by co-culture with cortactin-expressing cells. Since the co-cultured cells are separated by permeable filters, cortactin-expressing cells must secrete growth-supporting autocrine factors to rescue the cortactin-KD cells. Overall, cortactin expression modulates multiple cellular traits that may allow survival in a tumor environment, suggesting that the frequent overexpression of cortactin in tumors is not an epiphenomenon but rather promotes tumor aggressiveness.

Abstract
Steps taken to establish an environmental quality standard (EQS) for aluminium are described. The range of water types in England and Wales and the concentrations of low molecular weight (active) forms of aluminium have been assessed in order to evaluate the risk posed by aluminium in surface waters. Levels of low molecular weight forms of aluminium are mainly in the range 0-25 microg l(-1). Data suggest that dissolved aluminium might form the basis of a reasonably useful prediction of active aluminium leading to a simplified approach to compliance monitoring of an EQS set in terms of active aluminium.

Abstract
Large cell calcifying Sertoli cell tumor of the testicle is a rare, hormonally active sex cord-stromal tumor seen in patients with Carney complex. When such tumors occur bilaterally, treatment options for preserving fertility and addressing the secondary effects of excess hormone production must be considered. The availability of specific antiestrogen drugs means that bilateral orchiectomy for this benign tumor may no longer be warranted. Testicular-sparing surgery and advances in reproductive technology may also improve the overall prognosis for fertility. Gynecomastia in prepubescent boys can be emotionally very distressing. Approximately two thirds of teenaged boys will develop some degree of breast enlargement that spontaneously regresses as testosterone levels rise (Ill Med J 1938;73:113). In all cases, a thorough history and physical examination are required to exclude nonphysiologic causes such as drugs, pulmonary disease, chronic liver disease, exogenous estrogens, and estrogen-producing tumors (Seashore J. Disorders of the breast. In: Rowe MI, O'Neill JA, Grosfeld JL et al, editors. Pediatric surgery, 5th ed. St Louis (MO): Mosby Year Book, 1998). We report on a child who presented with a 2-year history of gynecomastia with associated bilateral testicular swellings and discuss a novel treatment strategy for managing bilateral testicular tumors in the context of the Carney complex.
