Abstract
Disturbances in sexual function and depression are a common feature in women with chronic renal failure. Living-donor kidney transplantation seems to warrant better results than its cadaveric counterpart in many aspects but its impact on post-transplantation sexual function remains unknown. This study aimed to compare post-transplantation sexual function and depression in women receiving kidney grafts from living and deceased donors. From a single-center prospective database of 2016 renal transplantations between June 2011 and June 2013, we enrolled 50 sexually active women after kidney transplantation. Female sexual function was evaluated with the Female Sexual Function Index Questionnaire (FSFI) and depression was assessed using the Beck Depression Inventory-II (BDI-II) scale. Thirty-four patients referred the questionnaires. The sexual domains of satisfaction and desire were significantly better in living-donor receptors; in all other domains evaluated by FSFI no statistically significant difference was encountered between groups, although living-donor receptors tended to report better function. Total BDI-II was well correlated with total FSFI score in our study cohort (Spearman's rho = -0.80, P < .001). Only 34.6% of women referred to have discussed sexual issues with their physicians before transplantation, whereas 73.1% stated it would have been important. In conclusion, living-donor transplantation exerted a positive effect on women's sexual function.

Abstract
Erectile dysfunction is experienced by 50% of men with end-stage renal disease (ESRD) and uremia. The origin of this dysfunction is multifactorial. The aim of this study was to compare living donor versus cadaveric donor transplant recipients regarding male sexual function. Seventy-seven sexually active male kidney transplant recipients (44 from living donors; 33 from cadaveric donors) were randomly selected from our single-center prospective database of 2016 renal transplants. Epidemiological and clinical data were collected between June 2010 and June 2011. Male sexual function was evaluated with the International Index of Erectile Function questionnaire (IIEF-15). We assessed the prevalence of male sexual dysfunction according to established cutoff points for each of the IIEF-15 domains. Mann-Whitney and Pearson's chi- square statistical tests were used to compare continuous and categorical variables, respectively. The median age at the time of completion of the questionnaires was 43 and 51 years (P = .003) with median times from transplantation was of 36 and 42 months for living donor and cadaveric donor recipients, respectively (P = .31). Median durations of ESRD before surgery were 17.5 and 57 months for living donor and cadaveric donor recipients, respectively (P < .001). Living donor and cadaveric donor recipients had median creatinine clearance values of 55 and 57 mL/min, respectively (P = .44). Median time after renal transplantation for first sexual intercourse was 1 and 2 months for living donor and cadaveric donor recipients, respectively (P = .35). Median body mass indices for living donor and cadaveric donor recipients were 24.8 and 24, respectively (P = .31). Regarding sexual function domains, there were significant differences only for intercourse satisfaction. In our cohort, living donor recipients tended to be younger, have shorter time of ESRD, and less incidence of hypertension or diabetes mellitus but with greater tobacco use. In conclusion, living donor transplantation exerted a favorable impact on sexual function.

Abstract
OBJECTIVES To provide an up-to-date review of the available literature on laparoscopic cryotherapy for small renal masses (SRMs) including technique description, indications and outcomes. METHODS A systematic literature search was conducted in March 2012, using MEDLINE and EMBASE via Ovid databases, to identify studies on laparoscopic cryotherapy for SRMs published during the last 10 years. Only English-language and human-based full manuscripts reporting case series studies with >20 participants, patient characteristics, efficacy and safety data were included. RESULTS No randomised controlled trials (RCTs)were identified. In total, 27 full reports addressing laparoscopic cryoablation (LCA) for SRMs were selected. The number of patients per study ranged from 20 to 144. Mean age of treated patients across the series ranged from 62 to 73 years. Mean size of renal tumors ranged from 2.7 to 4 cm, being in most cases <3 cm. The number of cryoprobes used for cryoablation ranged from 1 to 6, and only 10 series described the use of 17-gauge (1.47 mm) third-generation needles. Overall, more than 55% of all ablated lesions were pathologically confirmed RCC. Mean follow-up ranged from 9 to 93 months. Only 7 series presented a long-term follow-up of more than 36 months. Most studies were limited by a relatively short follow-up. At least four urologic groups reported intermediate- and long-term outcomes. Persistence rates ranged from 0% to 17% and recurrence rates ranged from 0% to 14%. Overall complication rates ranged from 0% to 40%. CONCLUSIONS Retrospective observational data and a few prospective series on LCA of SRMs show acceptable oncological 3- to 5-year outcomes with a low recurrence rate. It has proven to be a safe procedure with an overall low complication rate. It is mainly indicated for SRMs in elderly patients affected by co-morbidity and high surgical risk bearing tumours in the anterior valve of the kidney or in contact with the ureter or neighbouring organs.

Abstract
Extracellular and intracellular reactive oxygen species attack different targets and may, therefore, result in different forms of oxidative stress. To specifically study an oxidative stress induced by a regulated intracellular flux of a defined reactive oxygen species in endothelium, we used immunotargeting of the H(2)O(2)-generating enzyme glucose oxidase (GOX) conjugated with an antibody to platelet-endothelial cell adhesion molecule (PECAM)-1, an endothelial surface antigen. Anti-PECAM-(125)I-GOX conjugates specifically bind to both endothelial and PECAM-transfected cells. Approximately 70% of cell-bound anti-PECAM-(125)I-GOX was internalized. The cell-bound conjugate was enzymatically active and generated H(2)O(2) from glucose. Use of the fluorescent dye dihydrorhodamine 123 revealed that 70% of H(2)O(2) was generated intracellularly, whereas 30% of H(2)O(2) was detected in the cell medium. Catalase added to the cells eliminated H(2)O(2) in the medium but had little effect on the intracellular generation of H(2)O(2) by anti-PECAM-GOX. Both H(2)O(2) added exogenously to the cell medium (extracellular H(2)O(2)) and that generated by anti-PECAM-GOX caused oxidative stress manifested by time- and dose-dependent irreversible plasma membrane damage. Inactivation of cellular catalase by aminotriazole treatment augmented damage caused by either extracellular H(2)O(2) or anti-PECAM-GOX. Catalase added to the medium protected either normal or aminotriazole-treated cells against extracellular H(2)O(2), yet failed to protect cells against injury induced by anti-PECAM-GOX. Therefore, treatment of PECAM-positive cells with anti-PECAM-GOX leads to conjugate internalization, predominantly intracellular H(2)O(2) generation and intracellular oxidative stress. These results indicate that anti-PECAM-GOX 1) provides cell-specific intracellular delivery of an active enzyme and 2) causes intracellular oxidative stress in PECAM-positive cells.

Abstract
Experiments were undertaken to analyze proviral DNA in primary (wing web) and visceral sarcomas arising in FP chickens infected with BH-RSV(RAV-2). Using the degree of heterogeneity of BH-RSV proviral integration sites as a measure of the degree of polyclonality of sarcoma tissue, we observed that a high proportion of the visceral sarcomas examined comprised dominant clones, independently of whether these sarcomas were isolated from immune-suppressed or nonsuppressed infected chickens; by contrast, a marked heterogeneity of BH-RSV proviral integration sites was noted with primary sarcoma tissue. Several visceral sarcomas containing dominant clones were characterized by the integration of a deleted form of the BH-RSV provirus. In addition, all of the primary and visceral sarcomas exhibited sequences specific for the RAV-2 provirus, and both types of sarcoma tissue were competent for infectious sarcoma virus production.

Abstract
Sarcomas arising in FP chickens infected with subgroup B avian sarcoma virus at increasing times posthatch were compared for their capacity to mediate recruitment of new sarcoma cells by infectious virus production. This comparison was premised on the observation that primary sarcoma growth is much slower when older chickens are infected with avian sarcoma virus. As measured in a transplantation assay, no age-related diminution in the recruitment capacity of sarcoma tissue from virus-infected transplant donors was observed, despite the marked age-related differences in their patterns of primary sarcoma growth. These observations establish that a diminished recruitment capacity is not required for slow primary sarcoma growth. The capacity to induce the formation of sarcomas at sites distal to the primary sarcoma was correlated with a strong recruitment capacity.

Abstract
Between 1961 and 1976, 387 patients with Hodgkin disease were examined, evaluated, and treated at the Instituto Portugues de Oncologia de Francisco Gentil. After reviewing histological and clinical staging presentation, the authors retrospectively analyzed the results obtained with 303 patients classified in clinical stages I, II, and III (A, B) who were treated with or without chemotherapy in two time periods (before and after 1970) according to individual therapeutic modalities. The improvement of the 5-year survival rates in the last period was associated with the introduction of extended-field irradiation and multidrug chemotherapy (MOPP). However, the incidence of serious complications was higher in the group of patients subjected to combined field irradiation and MOPP. The authors suggest a stricter protocol based on the current recommendations for the treatment of Hodgkin disease in order to achieve better results with minimum possible hazards.
