Abstract
PURPOSE Urban cancer survivors have been shown to have better opportunities for recovery of health and wellbeing than their rural counterparts. Whilst there is a considerable body of evidence that explores urban people with cancers' experiences and outcomes, there is a dearth of research that explicitly explores 'urban cancer survivorship' in its own right. This study aimed to explore cancer survivorship in urban people living with cancer who have completed primary treatment. METHODS Secondary analysis of in-depth interview data (n = 18) with adults living with cancer who resided in urban parts of the UK. Data were drawn from a broader study on self-management of people living with cancer. An adapted version of Foster and Fenlon's recovery of health and wellbeing in cancer survivorship framework was used to inform the analysis of the data. RESULTS Recovery of health and wellbeing was impacted by a variety of contributory factors, which had a largely positive impact. Access to amenities, social support, travel, and healthcare factors were opportunities for urban cancer survivors, whilst pollution, traffic and a lack of green spaces acted as challenges for health management. CONCLUSION This study demonstrated how urban residency acted as both a barrier and a facilitator to recovery of health and wellbeing in urban cancer survivors following the completion of primary treatment. Area of residence should be taken into account by health providers and policymakers supporting cancer survivorship and the views of those with lived experiences should be included in informing future practice.

Abstract
Peanut allergy is on the rise in industrialized countries, affecting 1%–4.5% of children and generally persisting into adulthood. It is associated with a risk of severe anaphylaxis and is one of the major causes of food allergy-induced deaths. Health-related quality of life is significantly impaired for patients and affected families due to food restrictions attributable to omnipresent precautionary allergen labeling, constant risk of potentially life-threatening reactions, and limitation of social activities. Oral immunotherapy (OIT) has emerged as a valid treatment option for patients with IgE-mediated peanut allergy, with randomized controlled trials and real-life studies showing a high rate of desensitization and a favorable safety profile, especially in young children. Ultimately, the decision to initiate peanut OIT relies on a multidisciplinary shared decision-making process, involving open, personalized and evidence-based discussions with patients and their caregivers.

Abstract
Background The role and importance of skin barrier as an immunologic organ and as a potent way of sensitization is well known. However, antibiotics anaphylaxis following skin sensitization has not been reported. Case presentation We describe the first case of intravenous clindamycin anaphylaxis, with likely sensitization due to previous topical exposure to clindamycin gel for acne in a 14-year-old boy with history of atopy and mild atopic dermatitis. Conclusion This case highlights the potential sensitization to drug allergens, including antibiotics, via the skin.

Abstract
Egg is an ubiquitous allergen found in many food products. Current food allergy guidelines recognize the importance of consultation with a registered dietitian to ensure nutritional adequacy. However, there is a lack of evidence on its impact on the implementation of allergen avoidance strategies. Taking advantage of a well-characterized cohort of influenza vaccination in egg-allergic children (n=397), we tested the hypothesis that real-life professional dietary advice was associated with a decrease in accidental reactions to egg in allergic children with retrospective questionnaires. Lack of consultation with a dietitian was associated with a 1.89-fold increase in the risk of accidental reactions to egg (confidence interval: 1.47-2.42). The only other independent variable that predicted reactions was having had a history of acute reaction to egg prior diagnosis (relative risk=2.02; confidence interval: 1.64-3.00). These findings support the usefulness of referral to a food allergy-specialized dietitian at time of diagnosis in order to prevent future accidental reactions to egg.

Abstract
BACKGROUND The prevalence of peanut allergy in younger siblings of children with peanut allergy has been reported between 7% and 8.5%, but the anaphylactic risk at the time of introduction is currently unknown, which limits our ability to best counsel parents on this issue. OBJECTIVE To determine the risk of anaphylaxis and working parameters of allergy testing in this context. METHODS One hundred and fifty-four peanut-naïve younger siblings of peanut-allergic children underwent double-blinded skin testing, followed by parent-led peanut introduction. Questionnaires were dispensed to parents to investigate preferences with regard to peanut introduction in this subgroup. RESULTS Eight participants (5.2%) presented unequivocal IgE-mediated reactions to peanut upon introduction, including five anaphylaxes. These participants were significantly older compared to the rest of the cohort (median 4.0 vs 1.9 years, P = 0.04). The negative predictive value of skin prick test with peanut extract and peanut butter and of specific IgE was 99%, 100%, and 100%, respectively. Six peanut-tolerant participants had positive peanut allergy tests. The option of introducing at home without prior skin testing was associated with high levels of anxiety (median 8.4 on 10-point Likert scale) when compared to supervised introduction (median 3.8, P < 0.0001) or home introduction after negative skin test (median 4.3, P < 0.0001). CONCLUSIONS There is an increased risk of anaphylaxis upon peanut introduction in siblings of children with peanut allergy, and parents are reluctant to introduce at home without testing. Allergy testing prior to introduction is negative in over 90% of cases and carries a high negative predictive value.

Abstract
AIM To audit the levels of oral disease in those children whose disability required general anaesthesia for comprehensive dental treatment. METHODS An audit was conducted of oral disease levels in a sample of 51 children attending for treatment. RESULTS The proportion of untreated decayed teeth was 72%, previously extracted 25% and restored 3%. Very high levels of debris and gingival bleeding indices were found. There were very low proportions of previous restorations and past treatment had comprised mainly extractions. CONCLUSIONS There was a low restorative care index in both the primary and permanent dentitions indicating that high needs continue to exist in terms of comprehensive dental care for these Irish children.

Abstract
Recently, using hybrid Ad5/12 E1A-transformed rat cells, we identified at least two regions of Ad12 E1A which influence tumorigenicity. In this report, again using the hybrid Ad5/12 E1A-transformants, we show that expression of these same two Ad12 E1A regions not only correlates with down-regulation of cell surface MHC class I expression, but coincides with the presence of an altered form of the E1A-associated cellular protein, p300, detected as a more slowly migrating species in SDS-polyacrylamide gels. The decreased electrophoretic mobility of p300 from hybrid Ad5/12 E1A- and Ad12 E1A-transformants can be abolished by protein phosphatase treatment suggesting that the change in mobility results from differential phosphorylation of p300. We suggest that differential phosphorylation of p300 may be functionally significant in the context of phenotypic differences between Ad5 E1- and Ad12 E1-transformed cells.

Abstract
Anti-tumor activity of a recombinant adenovirus expressing murine IL-4 (AdCAIL-4) was investigated in a murine model of mammary adenocarcinoma. Primary tumor cells derived from mammary adenocarcinomas induced in transgenic mice by the middle T antigen gene of polyomavirus were infected with AdCAIL-4 and injected into syngeneic non-tumor bearing recipients. Expression of IL-4 by AdCAIL-4 transduced tumor cells significantly prolonged survival of all animals and prevented tumor development in 61% of recipient mice. When tumor bearing animals were injected intra-tumorally with AdCAIL-4, all animals survived at least 8 to 10 weeks longer than controls, and 50% of treated animals underwent complete tumor regression. Both en: vivo and in vivo treatment with AdCAIL-4 resulted in infiltration by eosinophils in and around the tumor site. Animals which had undergone complete tumor regression were protected from a second challenge suggesting that immunotherapy with Ad vectors expressing cytokines may protect from metastatic disease.

Abstract
We have developed human adenovirus 5 (Ad5) vectors expressing the wild type human p53 protein or a mutant p53 form under the control of the human cytomegalovirus immediate early gene promoter. Human cells infected with these vectors expressed high levels of p53, accumulating 20-40 fold more protein than found in normal human fibroblasts. The ability of the vectors to affect proliferation of cells in culture was assessed by measuring cell DNA synthesis and colony forming ability after infection with viruses. When the p53 deficient ovarian carcinoma cell line, SKOV-3, was infected with Adp53wt expressing the wild type (wt) p53 protein, a significant inhibition of cellular DNA synthesis was observed, relative to cells infected with Adp53m expressing mutant p53, or a control virus, AdLacZ, expressing bacterial beta-galactosidase. Inhibition was dependent on multiplicity of infection, with no significant effect below 5 pfu/cell, and maximal effect between 25 and 100 PFU/cell which resulted in approximately 95% inhibition of SKOV-3 cell DNA synthesis relative to mock infected cells. Infection of normal human fibroblasts with Adp53wt also inhibited DNA synthesis but to a significantly lesser degree. SKOV-3 cell survival, assayed by ability to form colonies, was reduced at least 10 fold after infection with Adp53wt compared to colony forming ability of cells after infection with either AdLacZ or Adp53m. The results of these studies indicate that p53 expressed by Ad vectors can inhibit proliferation in culture of p53 negative cells by at least 95%, and suggest that such vectors might similarly inhibit the proliferation of tumor cells in vivo.

Abstract
BACKGROUND B-type natriuretic peptide (BNP) is widely accepted in the evaluation of left ventricular systolic dysfunction and heart failure. However, little is known of the implications of elevated BNP levels in individuals with preserved systolic function (PSF). AIMS To investigate the drivers and clinical implications of elevated BNP levels in asymptomatic individuals with established PSF. METHODS We enrolled 154 individuals who all underwent physical examination, BNP evaluation and Doppler-echocardiographic studies. They were divided into those above and below the median BNP level (50 pg/ml). RESULTS Independent predictors of higher BNP were older age, more severe left ventricular hypertrophy (LVH), reduced E/A ratio and ischaemic heart disease. Survival and multivariable analysis demonstrated more death and/or admission in those above the median BNP (HR: 4.79, p=0.007). CONCLUSIONS Elevated BNP is the strongest, independent predictor of serious adverse cardiovascular outcomes in this population and requires closer clinical follow-up.

Abstract
Almost one in three Irish general practitioners (GPs) are now women, a ratio that has doubled since the early 1990s. The increase in numbers of women entering general practice training looks likely to continue and will have a formative influence on the future of general practice. This study investigates the implications for Irish general practice of the increasing feminization of the workforce. Questionnaires were sent to all (200) Irish vocationally trained female General Practitioners qualifying between 1995 and 2001. Sixty eight percent of respondents were currently working in full-ltime general practice. A majority wish to remain in general practice (88%) and potentially up to 90% intend to work part-time in the future. The ideal future work practices of this cohort are part-time partnerships, and over 50% are not in a position to work out of hours. To facilitate the career and working intentions of female vocationally trained GPs and to retain their services, there needs to be increased flexibility of hours of work, increased part-time partnerships and an Irish retainer scheme that will accommodate female GPs who cannot work full-time because of family commitments.

Abstract
Mouse oncostatin M (MuOSM) regulates the production of acute-phase proteins by hepatocytes as well as tissue inhibitor of metalloproteinases-1 (TIMP-1) production by fibroblasts in vitro. We have generated an adenovirus (Ad) encoding MuOSM and tested the effects of administration of recombinant AdMuOSM to mice in vivo. On intramuscular injection, AdMuOSM (5 X 10(7) plaque-forming units, pfu) induced an increase in serum levels of interleukin-6 (IL-6) as well as the acute-phase proteins serum amyloid A (SAP) and alpha1-acid glycoprotein (AGP) at day 1. SAP and AGP concentrations were elevated to greater levels at day 3 and decreased to near control levels at day 7. Intratracheal treatment with AdMuOSM induced TIMP-1 mRNA levels (as assessed by Northern blots) that corresponded to the presence of transgene MuOSM mRNA levels. TIMP-1 was elevated at day 1 and day 3 and less consistently at day 7 after administration. Intraperitoneal treatment with AdMuOSM also resulted in elevation of TIMP-1 mRNA in lung tissue. These results show that AdMuOSM can induce both local and systemic effects and demonstrate in vivo effects of OSM that are consistent with in vitro studies on acute-phase protein and TIMP-1 expression.

Abstract
We have developed a new helper adenovirus (Ad) based on serotype 2, Ad2LC8cCARP, for use in the Cre/loxP system (Parks et al. Proc Natl Acad Sci USA, 1996; 93: 13565-13570) to generate Ad vectors deleted of all protein coding sequences (helper-dependent Ad vectors (hdAd)). A comparison of Ad2LC8cCARP and our original helper virus (based on serotype 5, Ad5LC8cluc) showed that the two helper viruses amplified hdAd with a similar efficiency, and resulted in a similar yield and purity after large-scale preparation of vector. In vitro, the resulting hdAd2 had a similar transduction efficiency and expression kinetics of transgene (beta-gal) as the hdAd5. An important feature of the helper-dependent system is that all virion components, except the virion DNA, derive from the helper virus. Consequently, vectors produced with help from Ad2LC8cCARP were not neutralized by antibodies against Ad5, and vectors produced with Ad5 helper were resistant to neutralizing antibodies against Ad2. Analysis of transgene expression in mouse liver after intravenous injection of the Ad2-based hdAd showed that the vector could efficiently transduce the liver, and produce high levels of a foreign transgene, similar to those expressed by the hdAd generated with the Ad5 helper virus. Mice immunized with hdAd2 produced Ad2-neutralizing antibodies, which did not cross-react with hdAd5. To determine if successful repeat Ad vector administration could be achieved by sequential use of alternative Ad serotypes, we injected mice with hdAd2 (hSEAP) followed 3 months later by a lacZ-expressing hdAd of either the same or different serotype. Repeated administration of hdAd2 resulted in a 30- to 100-fold reduction in transgene expression compared with naive animals. In contrast, no decrease in transgene expression was observed when the second vector was of a different serotype. These results demonstrate that effective vector readministration can be achieved by the sequential use of hdAds based on alternative serotypes.

Abstract
CONTEXT The risk of acquiring babesiosis by blood transfusion is largely unknown since in areas where it is endemic it is often an asymptomatic infection. OBJECTIVE To investigate and treat a cluster of blood transfusion-associated babesiosis cases. DESIGN Case series and epidemiologic investigation. SETTING Urban inner-city hospital. PATIENTS Six persons who received Babesia microti-infected blood components from a donor. MAIN OUTCOME MEASURE Diagnosis and successful therapy of babesiosis following transfusion. RESULTS Six individuals (1 adult, 1 child, and 4 neonates) were exposed to products from a single blood donation by an asymptomatic Babesia-infected donor. Three of the 6 exposed patients became parasitemic. Polymerase chain reaction testing, animal inoculation studies, and indirect immunofluorescent antibody testing were used to confirm the presence of Babesia microti in the donor's blood and to establish the presence of infection in 3 of the 6 recipients. The 3 infected recipients and 1 additional recipient were treated without incident. CONCLUSION Physicians should consider babesiosis in the differential diagnosis of a febrile hemolytic disorder after blood transfusion. Prompt diagnosis is important since babesiosis is responsive to antibiotic therapy and, untreated, can be a fatal disease in certain risk groups.

Abstract
Evaluation of the potential role of dendritic cells (DCs) as adjuvants for tumor vaccination has focused primarily on techniques that load DCs with peptide tumor antigens. Our aim has been to optimize the induction of antitumor immunity by enhancing the ability of DCs to present tumor-associated antigens endogenously to the afferent lymphatic system in the appropriate major histocompatibility complex (MHC)-restricted context. We have used replication-defective adenovirus vectors (Ads) to transduce DCs with various genes, including tumor antigen genes. We found that 90% of murine bone marrow derived-DCs could be infected with an Ad vector expressing the beta-galactosidase gene and still retain their physiologic and phenotypic characteristics. Furthermore, we demonstrated that transgene expression was detectable in the spleen for at least 3 days following intravenous injection of Ad-transduced DCs. Using a polyoma middle T (PymT) transgenic murine mammary carcinoma model, we have shown that a single injection of 10(5)-4 x 10(6) DCs transduced with an Ad vector expressing PymT provided complete and specific protection against tumor cell challenge in 100% of vaccinated animals. Immunization against the PymT tumor by injection with the PymT expressing Ad vector alone resulted in varying degrees of effectiveness, was highly dependent upon the route of administration, and led to significant hepatic toxicity that was not seen in mice immunized with DC transduced with the Ad vector. Our results suggest that: (i) DCs can be very efficiently modified by ex vivo Ad transduction to express tumor-specific antigens, (ii) such modified DCs appear nontoxic and stimulate a potent antitumor response.

Abstract
Abstract
A number of complex mechanisms regulate the size and cellularity of an Ag-dependent granulomatous reaction and their accompanying cytokine production profiles. In the present study, Th1 (purified protein derivative (PPD)) and Th2 (schistosome egg Ag)-type granulomas were established to examine the role of IL-4 in lesion development and procollagen type III expression. PPD-sensitized mice were transfected via the airway with an adenovirus construct containing an IL-4 cDNA cassette, and the lungs were embolized with sized Ag-coated Sepharose beads. Granuloma development in response to the PPD bead challenge in control mice primarily consisted of mononuclear cells. In contrast, the overexpression of IL-4 in the IL-4 adenovirus-transfected animals demonstrated a significant increase in cellularity, size, procollagen type III expression, and accumulation of eosinophils. Analysis of mRNA and protein within the lung demonstrated significant expression of IL-4 in only the IL-4 adenovirus-transfected animals. The granuloma lesion size was significantly increased in the IL-4 adenovirus-transfected animals on days 2 and 5, reaching an approximate 50% increase compared with the control groups. Furthermore, procollagen type III mRNA expression was increased in the IL-4 adenovirus-transfected, PPD bead-embolized lungs. In contrast, when IL-4 was neutralized during Th2-type schistosome egg Ag bead granulomas, a decrease in procollagen type III was observed. These data indicate that the progression of certain granulomas may be regulated by the production of IL-4, thus altering the cellularity, size, and matrix composition of the inflammatory response.

Abstract
Daily systemic administration of hematopoietic growth factors can be associated with dose-limiting systemic side effects. To overcome this, we have investigated hematopoietic cytokine gene transfer to the marrow cavity of dogs by direct intramarrow injection of adenoviral vectors. In marrow culture, replication-deficient (E1-deleted) adenoviral vectors were able to transduce marrow stromal cells, demonstrating 30-fold greater expression than from other marrow cell types. High-level (ng/ml) cytokine production from transduced stromal cells persisted for 14 days in culture. Because adenovectors could efficiently transduce marrow stromal cells in culture, we investigated if stromal cells could also be transduced in vivo following direct intramarrow vector injection. Adenovectors with genes for interleukin 6 (IL-6) and Lac Z (beta-galactosidase) were injected directly into the marrow cavity of dogs resulting in protein expression localized to within the treated marrow. To evaluate this approach further in dogs, we constructed a vector expressing biologically active canine granulocyte-macrophage colony stimulating factor (GM-CSF). 293 cells infected with ADGM-CSF demonstrated prevalent GM-CSF mRNA by Northern blot and 135 +/- 30 ng/ml of protein as measured by enzyme-linked immunosorbent assay (ELISA). In vitro bioactivity of protein expressed was confirmed by canine GM colony-forming assay (CFU-GM). In vivo high-level protein production was noted in supernatants of marrow aspirates 72 hr following direct intramarrow administration of ADGM-CSF (baseline mean +/- SEM, 27 +/- 22 ng/ml, 72-hr sample 921 +/- 461 ng/ml). A localized myeloid expansion of marrow and significant peripheral leukocytosis (neutrophilia) were noted in all ADGM-CSF-treated dogs. Peripheral blood changes lasted for up to 3 weeks in dogs following single intramarrow injection. Thus, adenoviral cytokine expression from the marrow of a single large bone (ilium) led to compartmentalized expression of growth factor and an increase of hematopoiesis sufficient to cause peripheral blood changes in a large animal model.

Abstract
In summary, we have been able to demonstrate that adenovirus vectors are valuable tools in examining the roles played by individual cytokines in lung responses and inflammation. These viral vectors have marked trophism for the epithelial cells of the lung and are highly efficient in transferring the genes into these lining cells. This results in significant expression of cytokines both within the lumen and the parenchyma of the lung. As a result of an individual cytokine being overexpressed, there are cytokine-specific changes seen-IL-6 resulting in lymphocytosis, MIP2 resulting in neutrophil accumulation, RANTES resulting in monocyte accumulation, TGF beta resulting in monocytosis but no fibrosis, and GM-CSF most surprisingly resulting in tissue eosinophilia, granuloma formation, and subsequently the onset of fibrosis. These vectors have helped pinpoint the role of a number of the cytokines in inducing chronic inflammatory changes to the lung and imply that a single cytokine may not be the only trigger resulting in chronic changes within the lung parenchyma.

Abstract
Replication-defective adenoviral vectors are capable of localized transfer and expression of incorporated gene product in lung tissue. We have constructed an adenoviral vector that expresses rat macrophage inflammatory protein (MIP)-2, a C-X-C chemokine specifically chemotactic for neutrophils, Supernatants from 293 cells, infected with the adenoviral MIP-2 (ADMIP-2) construct, showed potent chemotactic activity and the ability of the ADMIP-2 vector to transcribe and make functional protein was confirmed. In vivo analysis of bronchoalveolar lavage fluid from rats after intratracheal instillation of ADMIP-2 (10(9) plaque-forming units) showed a 10-fold increase in the absolute number of neutrophils in bronchoalveolar lavage fluid as opposed to rats treated with an equal titer of an E1-disabled control virus expressing firefly luciferase (ADCA-18). Neutrophils constituted 65% of total BAL cells with alveolar macrophages being the other major cell type recovered. Rat MIP-2 protein was increased (nanograms per milliliter) in bronchoalveolar lavage fluid over a period of 7 days in ADMIP-2-treated animals. MIP-2 mRNA was demonstrated by Northern blot analysis in lung tissue, and histological analysis confirmed the presence of massive localized tissue neutrophilia. Evidence of chronic tissue injury and repair (ie, fibrosis) was not detected up to 2 weeks after the neutrophil infiltrate had resolved, subsequent to decreased chemokine presence. Adenoviral gene transfer proved an effective tool for the assessment of lung tissue expression of this chemokine in vivo and is useful in developing rodent models of tissue neutrophilia.

Abstract
The infection of epithelia] swine testicle and intestinal porcine epithelial (IPEC-1) cell lines by adenovirus type 5 (Ad5) has been studied in vitro by using an Ad5-luciferase recombinant containing the firefly luciferase gene as a reporter. Porcine cell lines supported Ad5 replication, showing virus titers, kinetics of virus production, and luciferase expression levels similar to those obtained in human 293 cells, which constitutively express the 5'-end 11% of the Ad5 genome. The tropism of Ad5-based vectors in swine and its ability to induce an efficient immune response against heterologous antigens expressed by foreign genes inserted in these vectors has been determined. Ad5 vectors replicate and express heterologous antigens in porcine lungs and mediastinal and mesenteric lymph nodes. Significant levels of heterologous antigen expression were also demonstrated in the small intestine (jejunum and ileum), but Ad5 replication in this organ was very poor, suggesting that Ad vectors undergo an abortive replication in the porcine small intestine. The tissues infected by Ad5 were dependent on the inoculation route. The oronasal route appeared to be best for inoculation of bronchus-associated lymphoid tissue infection, while the intraperitoneal route was best for gut-associated lymphoid tissue infection. Epithelial cells of bronchioles, macrophages, type II pneumocytes, and follicular dendritic cells were identified as targets for Ad5, while epithelial cells of the intestine were not infected by Ad5. Viruses with a deletion from 79.5 to 84.8 map units in the E3 region, with or without heterologous inserted genes, replicated to lower levels in porcine tissues than did wild-type Ad5. It was also shown that an Ad5 recombinant expressing the four antigenic sites (A, B, C, and D) of transmissible gastroenteritis coronavirus (TGEV) spike protein induced in swine immune responses which neutralized TGEV infectivity. In addition, porcine serum from Ad-TGEV-immune animals provide passive protection when mixed with fully virulent TGEV and orally administered to highly susceptible newborn piglets. These results taken together indicate that swine may be a good animal model for human Ad5 lung infection to aid in the evaluation of candidate adenovirus vaccines and that Ad5 may be suitable as a recombinant viral vaccine or for other applications in swine.

Abstract
BACKGROUND Transfection of the costimulatory molecule B7-1 into some murine tumors can increase antitumor immunity and eradicate tumor growth. The purpose of this work was to construct an adenovirus-B7 (Ad-B7) expression vector and study B7-1 gene transfer into human cancer cells. METHODS The human B7-1 cDNA was ligated into an expression cassette containing the human cytomegalovirus immediate early gene promoter and then inserted into the E1 region of the Ad5 genome by homologous recombination. The resulting Ad-B7 vector was used to infect established cancer cell lines and freshly resected cancers. Resected tumors were disaggregated into single cell suspensions by mechanical mincing and enzymatic digestion. Surface expression of B7-1 after infection was verified by flow cytometry. RESULTS Expression kinetics in three cell lines showed that infected cells began to express B7-1 within 24 h. The proportion of B7-1+ cells continued to increase during the next 48 h, after which expression remained relatively constant during the next 5 days (up to 98% B7-1+ cells). Fresh tumor cells from various cancers displayed similar kinetics, but with greater variability in the proportion of cells expressing B7-1 (13% to 95% B7-1+ cells). Cancers which were successfully infected included 3 colorectal adenocarcinomas, 2 leiomyosarcomas, 2 lung squamous cell carcinomas, and 1 renal cell carcinoma. CONCLUSIONS The Ad-B7 vector is a rapid and efficient means of gene transfer which does not require host cell proliferation. The ultimate objective is to engineer autologous tumors to express B7-1 and vaccinate cancer patients in an adjuvant or palliative setting.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a pleiotropic cytokine whose expression is increased in numerous respiratory diseases, particularly in asthma. However, the role of GM-CSF in the pathogenesis of these conditions in vivo remains unclear. Here, we report the functional activities of GM-CSF highly expressed in rat lung after intrapulmonary transfer of the gene coding for murine GM-CSF by using an adenoviral vector. This high, transient expression of GM-CSF led to the sustained but self-limiting accumulation of eosinophils and macrophages associated with tissue injury in the lung followed by varying degrees of irreversible fibrotic reactions observed in later stages. These results suggest that GM-CSF plays a previously unrealized role in the development of respiratory conditions characterized by eosinophilia, granuloma and/or fibrosis and provide the rationale for targeting this molecule in these diseases.

Abstract
Ten recombinant adenoviruses expressing either fragments of 1135, 1587, or 3329 nt or the full-length spike gene of transmissible gastroenteritis coronavirus (TGEV) have been constructed. These recombinants produce S polypeptides with apparent molecular masses of 68, 86, 135, and 200 kDa, respectively. Expression of the recombinant antigen driven by Ad5 promoters was inhibited by the insertion of an exogenous SV-40 promoter. Most of the recombinant antigens remain intracytoplasmic in infected cells. All the recombinant-directed expression products contain functional antigenic sites C and B (Gebauer et al., 1991, Virology 183, 225-238). The recombinant antigen of 135 kDa and that of 200 kDa, which represents the whole spike protein, also contain antigenic sites D and A, which have previously been shown to be the major inducers of TGEV-neutralizing antibodies. Interestingly, here we show that recombinant S protein fragments expressing only sites C and B also induced TGEV-neutralizing antibodies. The chimeric Ad5-TGEV recombinants elicited lactogenic immunity in hamsters, including the production of TGEV-neutralizing antibodies. The antisera induced in swine by the Ad5 recombinants expressing the amino-terminal 26% of the spike protein (containing sites C and B) or the full-length spike protein, when mixed with a lethal dose of virus prior to administration to susceptible piglets, delayed or completely prevented the induction of symptoms of disease, respectively.

Abstract
Recombinant Adenovirus type 5 constructs containing IL-6 cDNA can be used to infect cells in vitro and obtain a high level of IL-6 expression and secretion into culture media. Furthermore, Ad5-IL-6 viruses can also be used to infect Balb/c mice or Sprague-Dawley rats and obtain a high level of IL-6 expression that is sustained over a period of 3-5 days. Intratracheal infection was accompanied by dramatic increases in virus-encoded IL-6 mRNA levels in rat lung tissue, raised levels of IL-6 detected in bronchoalveolar lavage fluids and in serum, and IL-6-dependent sequelae such as liver acute phase responses. This occurs in a tissue-specific manner, depending on routes of infection by the virus. Rat lungs showed a prominent expansion (10 fold in numbers) of all classes of lymphocytes, including B cells, T helper cells (CD4+) and CTL (CD8+) at day 7 after infection which resolved significantly by day 12. Thus the associated biological effects of viral vector mediated IL-6 over-expression was also transient in nature. Other tissues can be infected with Ad5 and thus can also be induced to express selected genes in a transient fashion. We are currently examining the potential for Ad recombinant cytokine vectors in therapy for cancer and for bone marrow reconstitution after transplantation. Thus the use of recombinant Ad5 vectors may have a broad application in the study of cytokine function and possibly in future therapy as a transient gene transfer approach.

Abstract
Alpha-1-antitrypsin is a relatively common genetic deficiency that results in early emphysema. The liver as the natural source of most alpha-1-antitrypsin synthesis was the target organ selected for gene replacement therapy studies. Previous work used recombinant retroviral vectors that encode the human alpha-1-antitrypsin cDNA for ex vivo and direct in vivo transduction of hepatocytes in dogs and rodents. This approach led to low levels of human protein in the serum of recipients. In this study, recombinant adenoviral vectors that express the human alpha-1-antitrypsin cDNA under the transcriptional control of the phosphoglycerate kinase (PGK) or RSV-LTR promoters have been constructed and used for the direct transduction of mouse hepatocytes in vivo. The animals transduced with the recombinant adenoviral vectors had therapeutic serum levels of human alpha-1-antitrypsin of up to 700 micrograms/mL. Thus, adenovirus-mediated gene transfer of the hAAT cDNA into the liver was able to produce therapeutic serum concentrations of protein.

Abstract
An anonymous questionnaire was circulated to parents of young children to survey exposure to publicity about and attitudes to sperm donation (n = 192 couples; 50% response rate). Of those surveyed, 55% of men and women had seen or heard of the need for sperm donors; for 26% of couples, one or both partners had considered donation, and among half of those (13% of total) no objections to donating were raised. However, only two men had approached the clinic as donors. Objections to donation centred mainly on discomfort at having children outside their family, worry about future contact with donor insemination children, and worry about incest. Women were three times as likely to raise these objections as men. Of all respondents, 20% thought a donor should be used for only one recipient couple, while 50% suggested three or fewer families. Overall, 41% rated having non-identifying information about the recipient couple(s) as an important aspect of sperm donation, although only 9% of men and 17% of women considered personal contact important. While many people are aware of and receptive to the idea of being donors, very few act. Many would prefer that their spermatozoa were used for only one or a few couples about whom they had some information.

Abstract
The genome of adenoviruses is a double-stranded linear DNA molecule with inverted terminal repeats about 100 base pairs (bp) in length and a terminal protein covalently linked to the 5' nucleotide of each strand. Both of these features permit the formation of DNA circles, the inverted repeats allowing the circularization of single-stranded DNA and the terminal protein the joining of one or more molecules to yield double-stranded circles or concatemers. However, although the existence of covalently closed circles has been postulated, double-stranded viral DNA purified from virions or infected cells by conventional methods (that is, using proteases and phenol or chloroform) has always been obtained in a linear form. Here, we present evidence for the existence in adenovirus 5 (Ad5) infected cells of novel structures resulting from covalent head-to-tail joining of viral DNA molecules and show that these structures are due at least in part to the formation of covalently closed circles.

Abstract
The effect of cooling rate, warming rate, and duration of phase transition upon survival of frozen canine kidneys was investigated. In the present study, 11 kidneys out of 14 rapidly cooled (2--4degreesC/min) to --22degreesC and thawed (70--110degreesC/min) were viable following contralateral nephrectomy. The serum creatinine and BUN levels rose to a maximum of 8.4 and 30 mg%, respectively, on the eighth day post-contralateral nephrectomy. Average survival time was 10 days; however, two of the dogs in this group were allowed to survive, one for 3 months and one for over 2 years. Eight kidneys out of 16 slowly cooled (0.25-1.0degreesC/min) and either rapidly or slowly warmed (20-30degreesC/min) had function to produce small amounts of urine; however, they did not survive more than 5 days after contralateral nephrectomy. Cooling rates of 0.1 and 10degreesC/min were too harmful to the kidney to have renal function after reimplantation. The minimum renal cell damage as assessed by LDH and GOT in the post-freeze perfusate was found in the 2-4degreesC/min cooling rate following rapid warming (70degrees-110degreesC/min). Correlation of the duration of phase transition time to renal cell damage was linear for LDH and GOT (r=0.93). This result suggests that the duration of phase transition time also is an important factor during the freezing process, affecting post-thaw survival of canine kidneys.
