Abstract
Abstract
Background
Pediatric kidney transplant recipients (PKTR) are at risk of poor outcomes from COVID-19. Data on serologic responses to COVID-19 vaccines in PKTR remain sparse. We characterized the magnitude, breadth, and longevity of SARS-CoV-2 spike protein binding antibody responses in PKTR.
Methods
This single institution, prospective observational study enrolled PKTR presenting to a transplant clinic for routine care who had received or were eligible to receive a COVID-19 vaccine. Demographic data, history of prior COVID-19, and vaccination details were collected. Plasma samples obtained from standard-of-care residual specimens were analyzed for SARS-CoV-2 spike variant IgG using the MesoScale Discovery V-PLEX platform, which quantitatively measures antibodies to SARS-CoV-2 full-length spike wild-type (Wuhan-hu-1), Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1), and Omicron (B.1.1.529; BA.1) variants. Vaccine time points with > 5 samples available were analyzed. Geometric mean titers (GMTs) were calculated and log-transformed titers were compared using one-way ANOVA with Tukey’s post-hoc comparisons test.
Results
61 PKTR enrolled (Table1); 47 (77%) received at least 1 dose of COVID-19 vaccine in transplant clinic. 47 (77%) PKTR had at least one sample available for analysis, but serial specimens were lacking for many. By 6 months post-dose 2 of COVID-19 mRNA vaccination, spike (Wuhan-hu-1) IgG titers had waned to pre-vaccination levels (GMT 24 vs 47 binding antibody units (BAU)/mL, P=0.988). Administration of a 3rd dose of mRNA vaccine significantly boosted IgG antibodies (GMT 492 BAU/mL, P=0.007), and titers were maintained at 3 months (GMT 656 BAU/mL, P=0.001) but gradually waned by 6 months (GMT 223 BAU/mL, P=0.070). Administration of a 4th dose elicited a non-significant increase in titers (GMT 905 BAU/mL, P=0.870). Binding IgG antibodies to SARS-CoV-2 variant spike proteins post-vaccination were not significantly different from Wuhan spike.
Conclusion
In this cohort of PKTR, a 3rd dose of COVID-19 mRNA vaccine significantly boosted broadly cross-reactive binding IgG antibodies to SARS-CoV-2 spike variants, including Omicron. Decreasing titers at 6 months post-dose 3 raise concern for waning protective immunity and support 4th dose vaccination.

Abstract
STUDY QUESTION What is the scope of literature regarding women’s reproductive span in terms of definitions, trends and determinants? SUMMARY ANSWER The scoping review found a wide variation in definitions, trends and determinants of biological, social and effective women’s reproductive span. WHAT IS KNOWN ALREADY A woman’s reproductive span refers to her childbearing years. Its span influences a woman’s reproductive decisions. STUDY DESIGN, SIZE, DURATION A systematic scoping review was conducted. We searched MEDLINE, PubMed, JSTOR, CINAHL, Web of Science and Scopus electronic databases from inception to January 2021 without imposing language or date restrictions. We searched unpublished sources including the Global Burden of Disease, Demographic and Health Surveys, and National Health and Nutrition Examination Surveys. The list of relevant references was searched by hand. Sixty-seven reports on women’s reproductive span were included in this review. PARTICIPANTS/MATERIALS, SETTING, METHODS This scoping systematic review followed an established framework. The reporting of this scoping review followed the reporting requirements provided in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, Extension for Scoping Reviews. Identified records were independently screened and data were extracted. We performed conceptual synthesis by grouping the studies by available concepts of reproductive span and then summarized definitions, measures used, temporal trends, determinants, and broad findings of implications on population demographics and assisted reproduction. Structured tabulation and graphical synthesis were used to show patterns in the data and convey detailed information efficiently, along with a narrative commentary. MAIN RESULTS AND THE ROLE OF CHANCE A total of 67 relevant reports on women’s reproductive span were published between 1980 and 2020 from 74 countries. Most reports (42/67) were cross-sectional in design. Literature on reproductive span was conceptually grouped as biological (the interval between age at menarche and age at menopause), effective (when a woman is both fertile and engaging in sexual activity) and social (period of exposure to sexual activity). We summarized the working definitions, trends and determinants of each concept. Few articles addressed implications on demographics and assisted reproduction. LIMITATIONS, REASONS FOR CAUTION A formal assessment of methodological quality of the included studies was not performed because the aim of this review was to provide an overview of the existing evidence base regardless of quality. WIDER IMPLICATIONS OF THE FINDINGS The review produced a comprehensive set of possible definitions of women’s reproductive span, trends, and potential determinants. Further advancement of these findings will involve collaboration with relevant stakeholders to rate the importance of each definition in relation to demography and fertility care, outline a set of core definitions, identify implications for policy, practice or research and define future research opportunities to explore linkages between reproductive spans, their determinants, and the need for assisted reproduction. STUDY FUNDING/COMPETING INTEREST(S) This work received funding from the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), a cosponsored programme executed by the World Health Organization (WHO). The authors had no competing interests. STUDY REGISTRATION NUMBER N/A.

Abstract
Currently, we are experiencing a true pandemic of a communicable disease by the virus SARS-CoV-2 holding the whole world firmly in its grasp. Amazingly and unfortunately, this virus uses a metabolic and endocrine pathway via ACE2 to enter our cells causing damage and disease. Our international research training programme funded by the German Research Foundation has a clear mission to train the best students wherever they may come from to learn to tackle the enormous challenges of diabetes and its complications for our society. A modern training programme in diabetes and metabolism does not only involve a thorough understanding of classical physiology, biology and clinical diabetology but has to bring together an interdisciplinary team. With the arrival of the coronavirus pandemic, this prestigious and unique metabolic training programme is facing new challenges but also new opportunities. The consortium of the training programme has recognized early on the need for a guidance and for practical recommendations to cope with the COVID-19 pandemic for the community of patients with metabolic disease, obesity and diabetes. This involves the optimal management from surgical obesity programmes to medications and insulin replacement. We also established a global registry analyzing the dimension and role of metabolic disease including new onset diabetes potentially triggered by the virus. We have involved experts of infectious disease and virology to our faculty with this metabolic training programme to offer the full breadth and scope of expertise needed to meet these scientific challenges. We have all learned that this pandemic does not respect or heed any national borders and that we have to work together as a global community. We believe that this transCampus metabolic training programme provides a prime example how an international team of established experts in the field of metabolism can work together with students from all over the world to address a new pandemic.

Abstract
Background High data quality is of crucial importance to the integrity of research projects. In the conduct of multi-center observational cohort studies with increasing types and quantities of data, maintaining data quality is challenging, with few published guidelines. Methods The Cure Glomerulonephropathy (CureGN) Network has established numerous quality control procedures to manage the 70 participating sites in the United States, Canada, and Europe. This effort is supported and guided by the activities of several committees, including Data Quality, Recruitment and Retention, and Central Review, that work in tandem with the Data Coordinating Center to monitor the study. We have implemented coordinator training and feedback channels, data queries of questionable or missing data, and developed performance metrics for recruitment, retention, visit completion, data entry, recording of patient-reported outcomes, collection, shipping and accessing of biological samples and pathology materials, and processing, cataloging and accessing genetic data and materials. Results We describe the development of data queries and site Report Cards, and their use in monitoring and encouraging excellence in site performance. We demonstrate improvements in data quality and completeness over 4 years after implementing these activities. We describe quality initiatives addressing specific challenges in collecting and cataloging whole slide images and other kidney pathology data, and novel methods of data quality assessment. Conclusions This paper reports the CureGN experience in optimizing data quality and underscores the importance of general and study-specific data quality initiatives to maintain excellence in the research measures of a multi-center observational study.

Abstract
BACKGROUND AND OBJECTIVES Hypertension is highly prevalent in pediatric kidney transplant recipients and contributes to cardiovascular death and graft loss. Improper blood pressure (BP) measurement limits the ability to control hypertension in this population. Here, we report multicenter efforts from the Improving Renal Outcomes Collaborative (IROC) to standardize and improve appropriate BP measurement in transplant patients. METHODS Seventeen centers participated in structured quality improvement activities facilitated by IROC, including formal training in quality improvement methods. The primary outcome measure was the proportion of transplant clinic visits with appropriate BP measurement according to published guidelines. Prospective data were analyzed over a 12-week pre-intervention period and a 20-week active intervention period for each center and then aggregated as of the program-specific start date. We used control charts to quantify improvements across IROC centers. We applied thematic analysis to identify patterns and common themes of successful interventions. RESULTS We analyzed data from 5392 clinic visits. At baseline, BP was measured and documented appropriately at 11% of visits. Center-specific interventions for improving BP measurement included educating clinic staff, assigning specific team member roles, and creating BP tracking tools and alerts. Appropriate BP measurement improved throughout the 20-week active intervention period to 78% of visits. CONCLUSIONS We standardized appropriate BP measurement across 17 pediatric transplant centers using the infrastructure of the IROC learning health system and substantially improved the rate of appropriate measurement over 20 weeks. Accurate BP assessment will allow further interventions to reduce complications of hypertension in pediatric kidney transplant recipients.

Abstract
We report on the measurement of the γp→J/ψp cross section from E_{γ}=11.8 GeV down to the threshold at 8.2 GeV using a tagged photon beam with the GlueX experiment. We find that the total cross section falls toward the threshold less steeply than expected from two-gluon exchange models. The differential cross section dσ/dt has an exponential slope of 1.67±0.39 GeV^{-2} at 10.7 GeV average energy. The LHCb pentaquark candidates P_{c}^{+} can be produced in the s channel of this reaction. We see no evidence for them and set model-dependent upper limits on their branching fractions B(P_{c}^{+}→J/ψp) and cross sections σ(γp→P_{c}^{+})×B(P_{c}^{+}→J/ψp).

Abstract
BACKGROUND AND OBJECTIVES There is renewed interest in adrenocorticotropic hormone (ACTH) for the treatment of nephrotic syndrome. We evaluated the efficacy and safety of ACTH in children with frequently relapsing or steroid-dependent nephrotic syndrome in a randomized trial. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Participants aged 2-20 years old with frequently relapsing or steroid-dependent nephrotic syndrome were enrolled from 16 sites in the United States and randomized 1:1 to ACTH (repository corticotropin injection) or no relapse-preventing treatment. ACTH treatment regimen was 80 U/1.73 m2 administered twice weekly for 6 months, followed by 40 U/1.73 m2 administered twice weekly for 6 months. The primary outcome was disease relapse during the first 6 months. Participants in the control group were offered crossover to ACTH treatment if they relapsed within 6 months. Secondary outcomes were relapse after ACTH dose reduction and treatment side effects. RESULTS The trial was stopped at a preplanned interim analysis after enrollment of 31 participants because of a lack of discernible treatment efficacy. Fourteen out of 15 (93%) participants in the ACTH arm experienced disease relapse in the first 6 months, with a median time to first relapse of 23 days (interquartile range, 9-32), compared with 15 out of 16 (94%) participants and at a median of 21 days (interquartile range, 14-51) in the control group. There was no difference in the proportion of relapsed patients (odds ratio, 0.93; 95% confidence interval, 0.05 to 16.40; P>0.99) or time to first relapse (hazard ratio, 1.03; 95% confidence interval, 0.50 to 2.15; P=0.93). Thirteen out of 16 participants in the control group crossed over to ACTH treatment. Three out of 28 participants completed 12 months of ACTH treatment; the others exited the trial because of frequent relapses or side effects. There were no disease relapses after ACTH dose reduction among the three participants. Most side effects were mild and similar to side effects of corticosteroids. CONCLUSIONS ACTH at 80 U/1.73 m2 administered twice weekly was ineffective at preventing disease relapses in pediatric nephrotic syndrome.

Abstract
BACKGROUND Cardiometabolic risk (CMR) in young children has been measured using various approaches, including a continuous summary score that incorporates components such as adiposity, lipids, metabolic factors and blood pressure. OBJECTIVES The objective of this study was to comprehensively review definitions of continuous CMR scores in children <10 years of age. METHODS A scoping review was conducted using a systematic search of four scientific databases up to June 2016. Inclusion criteria were children <10 years of age and report of a continuous CMR score. RESULTS Ninety-one articles were included. Most studies were published from 2007 to 2016 (96%). Nearly all continuous CMR scores (90%) were calculated using the sum or the mean of z-scores, and many articles age-standardized and sex-standardized components within their own population. The mean number of variables included in the risk scores was 5 with a range of 3-11. The most commonly included score components were waist circumference (52%), triglycerides (87%), high-density lipoprotein cholesterol (67%), glucose (43%) and systolic blood pressure (52%). IMPORTANCE Continuous CMR scores are emerging frequently in the child health literature and are calculated using numerous methods with diverse components. This heterogeneity limits comparability across studies. A harmonized definition of CMR in childhood is needed.

Abstract
Aims The aim of this study was to determine the possible usefulness of the assay of the aminoterminal propeptide of type III procollagen and fibronectin in detecting connective tissue changes associated with gynecologic malignancies. Study Design Serum aminoterminal propeptide of type III procollagen and plasma fibronectin were measured in 36 women with gynecologic malignancies, 20 women with benign gynecologic tumors and 10 healthy women serving as controls. Results A significant serum propeptide was significantly high In the group with gynecologic malignancies and normal in the benign tumor group. The serum propeptide levels were related to of disease stage and presence of ascites in patients with ovarian carcinoma but not in those with cervical or endometrial carcinoma. In the follow-up study, a favorable clinical response was associated with normalizing propeptide levels whereas in rapidly progressive disease the levels fell initially but rose again. In partial response with ultimate progression, the propeptide concentration decreased but remained clearly above the normal range. No difference in plasma fibronectin was found among the malignant tumor, benign tumor and control groups. Conclusions The present study indicates that the aminoterminal propeptide of type III procollagen could serve as an additional, non specific marker to follow the clinical behavior of gynecologic malignancies and consequently of connective tissue metabolism reflecting tumor matrix interaction.

Abstract
BACKGROUND Few data exist for the genetic variants underlying the risk for steroid-sensitive nephrotic syndrome (SSNS) in children. The objectives of this study were to evaluate HLA-DQA1 and APOL1 variants as risk factors for SSNS in African American children and use classic HLA antigen types and amino acid inference to refine the HLA-DQA1 association. STUDY DESIGN Case-control study. SETTING & PARTICIPANTS African American children with SSNS or steroid-resistant nephrotic syndrome (SRNS) were enrolled from Duke University and centers participating in the Midwest Pediatric Nephrology Consortium. FACTOR Genetic variants in HLA-DQA1 (C34Y [rs1129740]; F41S [rs1071630]) and APOL1 high-risk alleles. OUTCOMES SSNS and SRNS. MEASUREMENTS Direct sequencing for the HLA-DQA1 and APOL1 variants in 115 African American children (65 with SSNS and 50 with SRNS). Imputation of classic HLA alleles and amino acids was done in 363 South Asian children. RESULTS The 2 HLA-DQA1 variants were significantly associated with SSNS in African American children (C34Y: P=5.7 × 10-11; OR, 3.53; 95% CI, 2.33-5.42; F41S: P=1.2 × 10-13; OR, 4.08; 95% CI, 2.70-6.28), but not with SRNS (C34Y: P=0.6; F41S: P=0.2). APOL1 high-risk variants were not associated with SSNS (P=0.5) but showed significant associations with SRNS (P=1.04 × 10-7; OR, 4.17; 95% CI, 2.23-7.64). HLA-DQA1*0201, HLA-DQB1*0201, and HLA-DRB1*0701 were the classic HLA alleles with the most significant associations with SSNS risk. The most significantly associated amino acid positions were HLA-DQα1 56 and 76 (both P=2.8 × 10-7). Conditional analysis revealed that these variants most likely account for the observed association. LIMITATIONS Modest sample size and limited statistical power to detect small to moderate effect sizes. Children studied may not be representative of all African American children in the United States. CONCLUSIONS HLA-DQA1 is a risk locus for SSNS, but not SRNS, in African American children, consistent with its role in SSNS risk in children of European, Asian, and African ancestries. There is little evidence of a significant role for the APOL1 high-risk alleles in childhood SSNS in African American children. Refinement of the HLA-DQA1 association identified the critical classic HLA antigen types and amino acids of the HLA-DQ α1 molecule.

Abstract
Abstract
Flexural fatigue performance of newly developed step-wise functionally graded (FG) composites has been investigated experimentally. Two unidirectional glass fiber (UGF)/epoxy FG composites with overall fiber volume fraction of 39.9 ± 0.3% and thickness of 6.0 ± 0.1 mm were fabricated using hand lay-up technique. The fabrication proposed technique depends on the variation of the composite structure achieved by three different templates. A non-functionally graded (NFG) composite laminate with the same overall fiber volume fraction and thickness was also fabricated using a fourth template for comparison. Each of the FG and NFG composites is made of six plies. Each ply has a thickness of 1.0 mm. This occurs by controlling the amount of matrix in each ply (constant matrix amount for all plies). Fatigue tests were performed at zero mean stress. A 20% reduction of the initial flexural stiffness was taken as a failure criterion. The S–N curves for the fabricated FG and NFG composites have been constructed as design curves. For FG composites, the effects of the spatial gradient of fiber content and plies stacking sequence on both S–N relationships and the specimens’ surface temperature rise were studied. Two-parameter Weibull distribution function was used to statistically analyze the fatigue life results.

Abstract
The problem of finding the relative position and orientation between the reference frames of a link-mounted sensor and the link has been formulated as a kinematic equation of the form H l H x = H x H c in terms of homogeneous transformation matrices by Shiu and Ahmad (1987). In this article, normal ized quaternions (Euler parameters) are used to transform the kinematic equation into two simple and structured linear systems with rank-deficient coefficient matrices. Closed-form solutions to these systems are derived using the generalized inverse method with singular-value decomposition analysis. To obtain a unique solution, two distinct robot movements are required. This leads to an overdetermined system of equations. A criterion for selecting the independent set of equations is developed. A set of closed-form formulae for the solution of these equations are derived. The selection crite rion and the solution formulae can be easily incorporated in application programs that require the calculation of the rela tive position and orientation of the sensor.

Abstract
Bovine tuberculosis (bTB), caused by Mycobacterium bovis (M. bovis), is a serious re-emerging disease in both animals and humans. The evolution of the Multi- and Extensively drug-resistant M. bovis strains (MDR-TB and XDR-TB) represents a global threat to public health. Worldwide, the disease is responsible for great economic losses in the veterinary field, serious threat to the ecosystem, and about 3.1% of human TB cases, up to 16% in Tanzania. Only thorough investigation to understand the pathogen's epidemiology can help in controlling the disease and minimizing its threat. For this purpose, various tools have been developed for use in advanced molecular epidemiological studies of bTB, either alone or in combination with standard conventional epidemiological approaches. These techniques enable the analysis of the intra- and inter-species transmission dynamics of bTB. The delivered data can reveal detailed insights into the source of infection, correlations among human and bovine isolates, strain diversity and evolution, spread, geographical localization, host preference, tracing of certain virulence factors such as antibiotic resistance genes, and finally the risk factors for the maintenance and spread of M. bovis. They also allow for the determination of epidemic and endemic strains. This, in turn, has a significant diagnostic impact and helps in vaccine development for bTB eradication programs. The present review discusses many topics including the aetiology, epidemiology and importance of M. bovis, the prevalence of bTB in humans and animals in various countries, the molecular epidemiology of M. bovis, and finally applied molecular epidemiological techniques.

Abstract
Multi-drug resistant (MDR) strains of Acinetobacter baumannii are responsible for an increasing number of opportunistic infections in hospitals. This study determined the prevalence of MDR A. baumannii isolates from intensive care units in a large tertiary-care hospital in Ismailia, Egypt, and the occurrence of different beta-lactamases in these isolates. Biotyping and antimicrobial susceptibility profile was done for isolated strains. Respiratory, urine, burn wound and blood specimens were collected from 350 patients admitted to different units; 10 strains (2.9%) of A. baumannii were isolated. All isolates showed resistance to more than 3 classes of antibiotics. Among the isolates, 6 isolates were carbapenemase producers, 2 were AmpC beta-lactamase producers and no isolates were metallo-beta-lactamase producers. Despite the low prevalence of A. baumannii infection in this hospital, the antibiotic resistance profile suggests that prevention of health-care-associated transmission of MDR Acinetobacter spp. infection is essential.

Abstract
Chronic hepatitis C virus (HCV) infection combined with occult hepatitis B virus (HBV) infection has been associated with increased risk of hepatitis, cirrhosis and hepatocellular carcinoma. This study aimed to determine the prevalence of occult HBV infection among Egyptian chronic HCV patients, the genotype and occurrence of surface gene mutations of HBV and the impact of co-infection on early response to treatment. The study enrolled 162 chronic HCV patients from Ismailia Fever Hospital, Egypt, who were HBV surface antigen-negative. All patients were given clinical assessment and biochemical, histological and virological examinations. HBV-DNA was detectable in sera from 3 patients out of the 40 patients who were positive for hepatitis B core antibody. These 3 patients were responsive to combination therapy at treatment week 12; only 1 of them had discontinued therapy by week 24. HBV genotype D was the only detectable genotype in those patients, with absence of "a" determinant mutations among those isolates.

Abstract
Tractability versus expressiveness is a problem underlying the current generation of problem solvers. It is desirable to specify the problem, along with knowledge required for its solution, in the most expressive means possible. However, from the perspective of the solver, the most efficient representation is the least expressive one. One solution to this problem is to devise a means of transforming an expressive problem description into an efficient problem solver. Knowledge compilation is the process of transforming a domain theory into a form specialized for the solution of a given problem set. This paper will present OPCOMP, a system devised to compile a first order quantifier free predicate calculus domain theory into a problem reduction solver.

Abstract
350 Background: We aim to illustrate the potential years of life lost (PYLL) and the average years of life lost (AYLL); secondary to genitourinary cancer in US during the period from 1972-2006 utilizing the Surveillance, Epidemiology and End Results (SEER) database, and illustrate the trends in the PYLL over this time period. Methods: PYLL were calculated to assess premature mortality trends in US for ureter, urinary bladder, kidney and renal pelvis, penis, testis, and prostate cancers. AYLL is the average of the differences between the actual ages at death and the expected remaining years of life for each person who died of cancer. Calculations were made based on the SEER cancer mortality data. Results: There were a total of 7,733,235 PYLL in both men and women secondary to urogenital cancer in US in the period from 1972-2006. In both males and females, the greatest PYLL were for kidney and renal pelvis cancer related mortality. In both sexes no improvement in PYLL secondary to ureteral and bladder cancer related mortality was observed. In males the greatest reduction in PYLL was in testicular cancer followed by prostate cancer. Conclusions: PYLL and AYLL are two powerful tools that reflect the impact of cancer related mortality on society. There has been an increasing trend in PYLL related to urogenital cancers over the last 35 years for both males and females. Kidney cancer had the highest increase in PYLL among both genders and more efforts are needed to address its progression. No significant financial relationships to disclose.

Abstract
This work aimed to assess seminal plasma heme oxygenase (HO) enzyme activity in oligoasthenoteratozoospermia (OAT) males with varicocele. Ninety-three men were divided according to their sperm count and clinical examination into: healthy fertile controls (n = 34), OAT without varicocele (n = 37) and OAT associated with varicocele (n = 22). They were subjected to semen analysis and estimation of seminal plasma HO enzyme activity in the form of bilirubin concentration. Seminal plasma HO enzyme activity decreased significantly in OAT cases compared with controls. Seminal plasma HO in OAT cases associated with varicocele decreased significantly compared with OAT cases without varicocele and healthy controls (mean +/- SD; 109.2 +/- 29.5, 283.6 +/- 88.4, 669.5 +/- 236.1 nMol bilirubin/mg ptn/min, P < 0.001). There was positive correlation between seminal plasma HO enzyme activity and sperm concentration, per cent of motile spermatozoa, number of motile spermatozoas ml(-1) and significant negative correlation with sperm abnormal forms per cent. It is concluded that varicocele has a negative impact on seminal HO enzyme activity. Therefore, improved seminal picture after correcting varicocele repair might be related, in part, to improved HO action(s).

Abstract
Symptomatic granular cell tumours of the neurohypophysis are rare sellar lesions. Preoperative prediction of the diagnosis on the basis of radiological appearance is useful as these tumours carry specific surgical difficulties. This is possible when the tumour arises from the pituitary stalk, rostral to a normal pituitary gland. This has not been emphasized previously.

Abstract
This work aimed to assess the efficacy of haeme oxygenase-1 (HO-1) cDNA-liposome complex transfer as a mediator of erectile signalling in aged rats. One hundred and fifty aged white albino rats were equally divided into five groups: controls, rats receiving lipofectamine, rats receiving intracorporeal HO-1 cDNA-lipsome complex, rats receiving HO-1 cDNA-liposome complex plus nitric oxide synthase (NOS) inhibitor, and rats receiving HO-1 cDNA-liposome complex plus HO inhibitor. Six rats were killed from each group after 12, 24 and 48 h, and after1 and 2 weeks. In dissected cavernous tissues, the following were assessed: HO-1 gene expression, Western blot for HO-1, HO enzyme activity, cGMP and histopathology. The results showed that HO-1 cDNA-liposome complex transfer led to a significant increase in cavernous tissue HO-1 protein, HO-1 gene expression, HO enzyme activity and cGMP up to 1 week. NOS inhibition exhibited no effect on HO-1 gene enhancement of cavernous tissue HO enzyme activity or cGMP, whereas inhibition of HO significantly decreased these parameters. Histopathology of cavernous tissue demonstrated a significant dilatation of helicine arteries in HO-1 cDNA-liposome complex treated group after 48 h compared with the controls. It is concluded that HO-1 cDNA-liposome complex transfer augments cavernous tissue cGMP with subsequent sinusoidal relaxation.
