Abstract
INTRODUCTION There is limited evidence on the outcomes of robotic partial nephrectomy (RPN) and open partial nephrectomy (OPN) in obese patients (BMI ≥ 30 kg/m2). In this study, we aimed to compare perioperative and oncological outcomes of RPN and OPN. METHODS We relied on data from patients who underwent PN from 2009 to 2017 at 16 departments of urology participating in the UroCCR network, which were collected prospectively. In an effort to adjust for potential confounders, a propensity-score matching was performed. Perioperative outcomes were compared between OPN and RPN patients. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS Overall, 1277 obese patients (932 robotic and 345 open were included. After propensity score matching, 166 OPN and 166 RPN individuals were considered for the study purposes; no statistically significant difference among baseline demographic or tumor-specific characteristics was present. A higher overall complication rate and major complications rate were recorded in the OPN group (37 vs. 25%, p = 0.01 and 21 vs. 10%, p = 0.007; respectively). The length of stay was also significantly longer in the OPN group, before and after propensity-score matching (p < 0.001). There were no significant differences in Warm ischemia time (p = 0.66), absolute change in eGFR (p = 0.45) and positive surgical margins (p = 0.12). At a median postoperative follow-up period of 24 (8-40) months, DFS and OS were similar in the two groups (all p > 0.05). CONCLUSIONS In this study, RPN was associated with better perioperative outcomes (improvement of major complications rate and LOS) than OPN. The oncological outcomes were found to be similar between the two approaches.

Abstract
Background There is no definitive evidence of the prognosis impact of histological variants (HVs) in patients who undergo surgical resection of a nonmetastatic renal cell carcinoma (nm-RCC) with venous tumor thrombus (TT). Objective To investigate the impact of HVs on the prognosis of patients with nm-RCC with TT after radical surgery. Design setting and participants Patients who underwent radical nephrectomy with the removal of the venous TT for an nm-RCC were included in a retrospective study. Outcome measurements and statistical analysis Three groups were identified: clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) RCC. The primary outcome measures (disease-free and overall survival [OS]) were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariate and multivariate Cox proportional hazard models were used to study the impact of HVs on survival. Results and limitations A total of 873 patients were included. The histological subtypes were distributed as follows: ccRCC in 780 cases, pRCC in 58 cases, and chRCC in 35 cases. At the time of data analysis, 612 patients were recurrence free and 228 had died. A survival analysis revealed significant differences in both OS and recurrence-free survival across histological subtypes, with the poorest outcomes observed in pRCC patients (p < 0.05). In a multivariable analysis, pRCC was independently associated with worse disease-free survival and OS (hazard ratio [HR]: 1.71; p = 0.01 and HR: 1.24; p = 0.04), while chRCC was associated with more favorable outcomes than ccRCC (HR: 0.05; p < 0.001 and HR: 0.02; p < 0.001). A limitation of the study is its retrospective nature. Conclusions In this multicentric series, HVs appeared to impact the medium-term oncological prognosis of kidney cancer with TT. Patient summary This study investigated the differences in oncological outcomes among histological variants (clear cell, papillary, and chromophobe) in a cohort of nonmetastatic renal cell carcinoma patients with venous tumor thrombus extension. We observed that these histological variants within this specific subgroup exhibit distinct outcomes, with papillary renal cell carcinoma being associated with the worst prognosis.

Abstract
PURPOSE The management of solitary kidney tumors is a surgical challenge, requiring irreproachable results on both oncological and functional outcomes. The goal of our study was to compare the perioperative results of robotic-assisted partial nephrectomy (RAPN) to open surgery in this indication. METHODS We led a multicentric study based on the prospectively maintained French national database UroCCR. Patients who underwent partial nephrectomy on a solitary kidney between 1988 and 2020 were included. Clinical and pathological data were retrospectively analyzed. The main outcome of the study was the analysis of the variation of the estimated glomerular filtration rate (eGFR) calculated according to MDRD at 3, 6, 12, and 24 months depending on the chosen surgical approach. The secondary outcomes were the comparison of Trifecta success, perioperative complications, and length of hospital stay. RESULTS In total, 150 patients were included; 68 (45%) in the RAPN group and 82 (55%) in the open surgery group. The two groups were comparable for all data. The variation of eGFR at 3, 6, 12, or 24 months was comparable without any significant difference between the 2 groups (p = 0.45). Trifecta was achieved in 40% of the patients in the RAPN group and 33% in the open group (p = 0.42). A significant difference was observed for the length of stay, 5 days for the robot group versus 9 days for the open surgery group (p < 0.0001). CONCLUSION In our study, the surgical approach did not modify functional results and we noted a significant decrease in hospital stay and complications in the RAPN group. RAPN is a safe and efficient method for management of kidney tumors in solitary kidneys.

Abstract
BACKGROUND Cool temperature egg storage prior to incubation is a common practice in the broiler industry; however, prolonged egg storage causes increased embryonic mortality and decreased hatchability and growth in surviving chicks. Exposing eggs to short periods of incubation during egg storage (SPIDES) reduces the adverse consequences of prolonged storage. SPIDES increases blastodermal cell viability by reducing apoptosis, though the counteracting mechanisms are unclear. To define the impact of prolonged storage and SPIDES, transcriptome analysis compared gene expression from blastoderms isolated from eggs exposed to the following treatments: control (CR, stored at 17 °C for 4 days), prolonged storage (NSR, stored at 17 °C for 21 days), SPIDES (SR, stored at 17 °C for 21 days with SPIDES), and incubated control (C2, stored at 17 °C for 4 days followed by incubation to HH (Hamburger-Hamilton) stage 2, used as the ideal standard development) (n = 3/group). Data analysis was performed using the CLC Genomics Workbench platform. Functional annotation was performed using DAVID and QIAGEN Ingenuity Pathway Analysis. RESULTS In total, 4726 DEGs (differentially expressed genes) were identified across all experimental group comparisons (q < 0.05, FPKM> 20, |fold change| > 1.5). DEGs common across experimental comparisons were involved in cellular homeostasis and cytoskeletal protein binding. The NSR group exhibited activation of ubiquitination, apoptotic, and cell senescence processes. The SR group showed activation of cell viability, division, and metabolic processes. Through comparison analysis, cellular respiration, tRNA charging, cell cycle control, and HMBG1 signaling pathways were significantly impacted by treatment and potential regulatory roles for ribosomal protein L23a (RPL23A) and MYC proto-oncogene, BHLH transcription factor (MYC) were identified. CONCLUSIONS Prolonged egg storage (NSR) resulted in enriched cell stress and death pathways; while SPIDES (SR) resulted in enriched basic cell and anti-apoptotic pathways. New insights into DNA repair mechanisms, RNA processing, shifts in metabolism, and chromatin dynamics in relation to egg storage treatment were obtained through this study. Although egg storage protocols have been examined through targeted gene expression approaches, this study provided a global view of the extensive molecular networks affected by prolonged storage and SPIDES and helped to identify potential upstream regulators for future experiments to optimize egg storage parameters.

Abstract
INTRODUCTION The objective of this narrative review was to report the most relevant data on the contemporary management of the main non-infectious emergencies of the lower urinary tract and genital organs. METHODS A narrative synthesis of the articles (French, English) available on the Pubmed database was carried out in June 2021. A request to the health surveillance network for emergencies and deaths (SurSaUD®, Santé Publique France) revealed original data on the epidemiology of non-infectious lower urinary tract and genital organs emergencies. RESULTS Non-infectious emergencies of the low urinary tract and genital organs represent a large panel of traumatic and non-traumatic situations, which constitute the 3rd reasons in urology for a consultation at the emergency department after, infectious disease (1st) and non-traumatic/non-infectious emergencies of the upper urinary tract (2nd). Hematuria is the 3rd urological reason for men for a consultation at the emergency department. Globally, pelvic trauma and genital traumatism mainly concern men. These emergencies rarely affect the prognosis but can be integrated into more complete situations which are likely to impact their treatment, particularly in multiple traumas. CONCLUSIONS In this article we report the epidemiology and the principles of management of non-infectious emergencies of the lower urinary tract and genital organs.

Abstract
OBJECTIVE To report the nature, diagnosis and therapeutic strategy of infectious emergencies in urology. MATERIAL AND METHODS Bibliographic research from Pubmed, Embase, and Google scholar in July 2021. A synthesis of the guidelines of national infectious diseases societies. RESULTS Urosepsis and complicated urinary tract infection have a standardized definition. Diagnosis and therapeutic strategy are presented for upper tract urinary infection, male urinary infection, healthcare associated urinary infection, symptomatic canduria and urinary infections of the elderly. Appropriate antibiotherapy should be tailored to the degree of severity, bacterial ecosystem, patient characteristics et localization of the infection. CONCLUSION Urinary infections can be critical and require immediate care. Knowledge of the guidelines and of appropriate diagnosis and therapeutics strategy improve care which should be rapidly applied, and collegial.

Abstract
OBJECTIVES Miniaturization of percutaneous nephrolithotomy techniques have led to their increased consideration for lower pole renal stones that can prove more challenging to reach using retrograde intrarenal surgery. The objectives of the present study were to evaluate and compare the outcomes of miniaturized percutaneous nephrolithotomy (miniPCNL) and retrograde intrarenal surgery (RIRS) for the treatment of lower pole renal stones. MATERIALS AND METHODS A retrospective study was performed in two academic urology departments between January 2016 and June 2019. Patients presenting with one or multiple stones of the lower calyx and/or renal pelvis, between 10 and 40mm based on CT-scan treated by miniPCNL or RIRS were included. RESULTS In all, 115 miniPCNL and 118 RIRS procedures were included. The rate of patients with no significant residual fragment (stone free rate) after the first procedure was higher in the miniPCNL group (69% vs. 52% P=0.01), especially for stones>20mm (63% vs. 24% respectively, P<0.001) and stones with a density≥1000HU (69% vs. 42% respectively, P=0.009). The higher stone free rate of miniPCNL was confirmed in multivariate analysis, adjusting for stone size and number of stones, OR 4.02 (95% CI 2.08-8.11, P<0.0001). The overall postoperative complication rate was higher in the miniPCNL group than in the RIRS group (23% vs. 11%, P=0.01). A second intervention for the treatment of residual fragments was necessary for 9.6% of patients in the miniPCNL group versus 30.5% of patients in the RIRS group (P<0.001). Pre-stenting rate and duration of ureteral drainage (2 [1-8] vs. 25 days [7-37], P<0.001) were lower in the miniPCNL group. CONCLUSIONS The stone free rate was higher after miniPCNL, especially for stones>20mm and with a density>1000 HU, but was associated with a higher risk of postoperative complications and a longer hospital stay. RIRS resulted in fewer complications at the cost of a higher retreatment rate and longer ureteral stenting. LEVEL OF EVIDENCE 3.

Abstract
Biobanking of turkey ovarian tissue appears to be the most cost-effective method for the long-term preservation of female genetics. However, to ensure the successful transplantation of biobanked ovarian tissue for breed or line revival, the transplantation and development of fresh ovarian tissue must be evaluated. To assess transplantability, ovaries from poults 1 to 15 days posthatch (dph) were cultured in ovo in chicken eggs for 6 d and compared with the equivalent fresh tissue. The viability of cultured ovarian tissue was evaluated visually, whereas the level of late-stage apoptosis was measured via the TUNEL assay. In addition, the diameter and density of prefollicular germ cells and follicles (primordial and primary) were measured to assess maturation. Results showed that all cultured grafts (74/74), on surviving chicken chorioallantoic membrane, were viable with low levels (0.8 ± 0.1%) of late-stage apoptosis. The diameter of prefollicular germ cells in cultured ovaries from poults at 5 and 7 dph were larger (P < 0.002) than that of their preculture counterparts but were not able to reach their in vivo size. No significant follicular growth was observed in ovaries cultured in ovo; however, prefollicular germ cell density was over 4-fold greater in ovaries cultured from 7 dph poults (81,030 ± 17,611/mm3) than in their in vivo counterpart (16,463 ± 6,805/mm3). Interestingly, cultured ovaries from all other ages displayed equal or lower (P ≤ 0.05) prefollicular germ cell densities than their in vivo counterparts. Cultured ovaries from poults at 5 and 7 dph also exhibited an increase (P ≤ 0.05) in follicle density compared with their preculture counterparts; whereas, cultured ovaries from 15 dph poults had decreased densities (P < 0.001) compared with their preculture counterparts. This study demonstrated that, although age of ovarian tissue cultured in ovo did not affect the overall viability, 7 dph ovaries appeared to have a better cellular morphology after culturing in ovo than other ages. In addition, we also demonstrated for the first time that avian follicles can form during tissue culturing in ovo.

Abstract
This study determined, for the first time, the different subpopulations of germ cells and stereological changes within the cortex of the functional left ovary during germ cell nest breakdown, and formation of the primordial follicle pool in the domestic turkey. This was accomplished by measuring the size, density, and count of prefollicular germ cells and primordial follicles in turkey poults between 1 and 35 days posthatch (dph). The percent volume (PV) of germ cells and follicles within the cortex was also calculated as a means of validating the counting technique. The total percent volume of germ cells and primordial follicles within the cortex ranged between 42 and 84%, suggesting that the counting technique was valid. Our findings show that before germ cell nest breakdown (5 dph), there were roughly 1,000,000 prefollicular germ cells within the cortex of the left ovary and that germ cell nest breakdown initiated between 5 and 7 dph, characterized by a decrease (P ≤ 0.001) in prefollicular germ cell density and the subsequent appearance of primordial follicles. Nest breakdown is followed on day 9 by the first increase (P ≤ 0.05) in size of prefollicular germ cells. These cells continue to grow throughout nest breakdown. The majority (>90%) of germ cell nest breakdowns concluded by 15 dph; although, the primordial follicle pool was not fully established until 35 dph, as determined by a total lack of prefollicular germ cells. At this point, the pool was comprised of an estimated 60,000 primordial follicles and shows that during nest breakdown and follicle pool formation, ∼94% of germ cells were lost. This 94% decrease in the number of germ cells during nest breakdown in the turkey is comparable to the domestic chicken but is greater than the average two-thirds which are lost in mammalian species.

Abstract
Identification of plasma and/or serum markers at birth that will predict animal performance may be useful for identifying animals susceptible to poor growth. Metabolomic analysis of plasma from newborn swine was used to identified potential metabolite differences between 8 pairs of littermates with similar birth weights but whose ADG differed by >50 g/d so that, at weaning (21 d), littermates differed in BW by 1.62 kg (P < 0.01). Plasma analysis failed to identify metabolic pathways impacted by growth, most likely because of the small sample population. Interestingly, despite comparative analysis of 576 metabolites between these slow-growing and normal-growing littermates, the relative abundance of only 36 metabolites differed between the pairs. Most of these metabolites could be eliminated as potential markers because of the difficulty with the extraction and rapid measurement of their plasma/serum concentrations. Histamine differed from most of these potential metabolite markers in that commercial sandwich ELISAs are readily available. Using an ELISA, we verified the metabolomic data, demonstrating that plasma histamine concentrations were 150% higher in slow-growing than normal growing littermates of similar birth weight (P < 0.05). Subsequently, a separate data set was obtained using swine from a different geographical location and genetic background and also showed that elevated histamine (ng/mL) at birth is associated with increased preweaning growth rate (P = 0.009, r = 0.306, n = 9 litters). Together, the data indicate that perinatal histamine concentrations may serve as a tool to identify potentially slower growing pigs and as a serum biomarker for predicting litter growth rate.

Abstract
OBJECTIVES To evaluate the prognostic role of the Bosniak classification on the long-term oncological outcomes of cystic renal cell carcinomas. MATERIAL AND METHOD In a national multicentric retrospective study, we included patients treated surgically for localized cystic RCC from 2000 to 2010. Patients with a follow-up of less than 4 years, benign tumors, and ablative treatments were excluded. The primary outcome was disease-free survival. RESULTS 152 patients met the inclusion criteria: Bosniak II (6%), III (53%), IV (41%), with a median follow-up of 61 (12-179) months. Characteristics of the population and the tumors were [median, (min-max)] age 57 (25-84) years old, tumor size 43 mm (20-280), RENAL score 7 (4-12), PADUA score 8 (5-14). Treatments were 55% partial nephrectomy, 45% radical nephrectomy, 74% open surgery, and 26% laparoscopy. In pathological report, cystic RCC were mainly of low grade (1-2, 77%) and low stage (pT1, 81%). The two main histological subtypes were conventional (56%) and papillary (23%) RCC. Staging at presentation and histological characteristics were similar between Bosniak III and IV, except for high grade which was more common in Bosniak IV (12 vs 36%, p < 0.01). The Bosniak classification was not predictive of the recurrence, as 5- and 10-year disease-free survival were similar in Bosniak III and IV (92% vs 92% and 84% vs 83%, p = 0.60). CONCLUSION The Bosniak classification is predictive of the risk of malignancy but not of the oncological prognosis. Regardless of the initial Bosniak categories, almost all cystic RCCs were of low stage/grade and had low long-term recurrence rate.

Abstract
We report the case of a 51-year old woman presenting pyelovenous fistula revealed by recurrent and serious thromboembolic events after ureteral ligation during emergency peripartum hysterectomy. Imaging reported a complete left ureteral obstruction, a fistula between the upper calix and the left renal vein and a renal function preserved. Uretero-vesical reimplantation was performed. The patient was well doing after 12 months. The authors wonder if pyelovenous fistula is responsible for prothrombotic state and maintaining renal function.

Abstract
OBJECTIVE To evaluate impact of the use of haemostatic agent in partial nephrectomy on perioperative outcomes. MATERIAL AND METHODS We reviewed the files of patients candidates for partial nephrectomy in our center between 2005 and 2010. The use of haemostatic agent and surgical procedure data were noted. Perioperative outcomes in haemostatic agent group were compared with perioperative outcomes in conventional surgical haemostasis group. RESULTS Among the 131 patients included, haemostatic agent was used in 91 cases (69.5%). There was no statistically difference between the two groups on age, sex, BMI, ASA score, tumor size and RENAL score. The use of haemostatic agent was more frequent for patients operated with laparoscopy (10.7%, P=0.04). Concerning perioperative outcomes, there was no difference between the two groups on surgical complications, transfusions, conversion to radical nephrectomy and hospital stay. Median warm ischaemia time was comparable into the two groups. In multivariate analysis, haemorrhage, complications and transfusions were not predicted by the use of haemostatic agent. CONCLUSION Use of haemostatic agent in partial nephrectomy had no benefice on perioperative outcomes in our series. Rapport between utility and cost for these agents must be discussed in partial nephrectomy.

Abstract
INTRODUCTION Thanks to the technical progress in instrumentation, laparoscopic surgery has made considerable advances over the last decade. Various robotic systems have been introduced to assist laparoscopic procedures. A new prototype of miniaturized laparoscope-holder (called the Light Endoscope Robot [LER]) has been developed by the TIMC-IMAG-CNRS Laboratory in Grenoble, France and is now currently marketed by the French company Endocontrol™ (La Tronche, Grenoble). The aim of this pilot study was to assess the LER in clinical practice. SUBJECTS AND METHODS This was a prospective, single-center study. The LER had already been successfully validated on preclinical laboratory and cadaveric trials. The study was conducted at the Grenoble University Hospital during standardized laparoscopic rectopexies on adult patients. Demographic and operative data and qualitative results were collected prospectively and analyzed retrospectively. All patients provided written informed consent, and the study was approved by the Regional Committee for Medical and Health Research Ethics. RESULTS Between March 2008 and September 2010, 16 adult patients underwent laparoscopic rectopexy assisted by the LER. All the patients were women with an average age of 63.6 years and an average body mass index of 24 kg/m(2). The procedure was completed in 15 patients. No conversion to open surgery was required. The postoperative mortality rate was 0%, and a complication occurred in 1 patient. The surgeon graded ease of use as 7 ± 2, global comfort as 8 ± 2, and quality of vision as 8 ± 2. CONCLUSIONS This pilot study demonstrated the feasibility, safety, and comfort for the surgeon of the laparoscopic rectopexy assisted by the miniaturized light endoscope-holder LER.

Abstract
AIM The aim of this paper was to evaluate the pathologic concordance of bilateral renal masses and the influence of synchronous or asynchronous occurrence on patient long term survival. METHODS Thirty-one consecutive patients with bilateral synchronous (N.=17, 55.0%) or asynchronous (N.=14, 45.0%) renal masses were retrospectively reviewed from January 2000 to December 2010. We included all patients with confirmed diagnosis on pathologic examination of a specimen or a percutaneous biopsy and evidence of angiomyolipoma on CT. Survival was assessed using the Kaplan-Meier method. RESULTS. The first lesion was larger than the second (60 vs. 30 mm, P<0.001). Pathologic concordance rate between tumors was 87.1%. A clear cell carcinoma was associated with a papillary carcinoma in 3.2%, and an angiomyolipoma in 6.4%. Median time of occurrence of a metachronous lesion was 50 months (IQR: 24; 92). Disease-free survival at 5 and 10 years was 87.2% and 78.5%. No statistical difference in disease free survival was observed between synchronous and metachronous tumors. conclusion: Discordant pathology between bilateral renal masses is uncommon, with a slight probability of benign tumor. Occurrence of a metachronous tumor can exceed 10 years.

Abstract
INTRODUCTION The aim of this study is to assess perioperative outcomes in a large series of robotic partial nephrectomy. PATIENTS AND METHODS We performed a retrospective analysis of 413 patients undergoing a robotic partial nephrectomy in a single center between June 2006 and December 2011. We analyzed demographic characteristics, operative and postoperative outcomes. RESULTS Mean age was 58.6±11.9 years, body mass index was 30.5±7.1 kg/m2 and median ASA score 3. Mean tumor size was 3.2±1.66 cm and was divided in low, moderate and high RENAL nephrometry score respectively in 40%, 44% and 16%. Operative time and warm ischemia time were respectively 191 and 21min. Mean estimated blood loss was 200 mL and there were 4.3% major complications (Clavien-Dindo System). Mean length of stay was 3.6 days. The latest estimated glomerular filtration rate (eGFR) was 74.84 mL/min×1.73 m2 with a mean decrease of 8.6%. In multivariate analysis, Charlson comorbidity index (P=0.005), preoperative eGFR (P<0.001) and warm ischemia time (P=0.0025) were found to be independent predictors of latest postoperative renal function. CONCLUSION Robotic partial nephrectomy is feasible and safe in experienced hands. In our study preoperative renal function, Charlson comorbidity index and warm ischemia time were independent predictors of latest eGFR.

Abstract
Background: Owing to the scarcity of upper urinary tract urothelial carcinoma (UUT-UC) it is often necessary for investigators to pool data. A patient-specific survival nomogram based on such data is needed to predict cancer-specific survival (CSS) post nephroureterectomy (NU). Herein, we propose and validate a nomogram to predict CSS post NU. Patients and methods: Twenty-one French institutions contributed data on 1120 patients treated with NU for UUT-UC. A total of 667 had full data for nomogram development. Study population was divided into the nomogram development cohort (397) and external validation cohort (270). Cox proportional hazards regression models were used for univariate and multivariate analyses and to build a nomogram. A reduced model selection was performed using a backward step-down selection process, and Harrell's concordance index (c-index) was used for quantifying the nomogram accuracy. Internal validation was performed by bootstrapping and the reduced nomogram model was calibrated. Results: Of the 397 patients in the nomogram development cohort, 91 (22.9%) died during follow-up, of which 66 (72.5%) died as a consequence of UUT-UC. The actuarial CSS probability at 5 years was 0.76 (95% CI, 71.62-80.94). On multivariate analysis, T stage (P<0.0001), N status (P=0.014), grade (P=0.026), age (P=0.005) and location (P=0.022) were associated with CSS. The reduced nomogram model had an accuracy of 0.78. We propose a nomogram to predict 3 and 5-year CSS post NU for UUT-UC. Conclusion: We have devised and validated an accurate nomogram (78%), superior to any single clinical variable or current model, for predicting 5-year CSS post NU for UUT-UC.

Abstract
The sperm storage tubules (SST) of the turkey hen, which are located in the uterovaginal junction (UVJ) of the oviduct, maintain viable sperm for up to 10 wk after a single insemination. The mechanisms of this in vivo sperm storage are poorly understood. Our objective was to evaluate mRNA and protein expression of avidin and 2 avidin-associated factors, avidin-related protein-2 (AVR2) and progesterone receptor, in the oviducts of 2 different lines to determine the extent to which they were sperm responsive and tissue specific. At 38 wk of age, Hybrid Grade Maker and Converter turkey hens were artificially inseminated with diluted semen (AI) or were sham-inseminated with extender alone (SI). Forty-eight hours after insemination, total RNA was extracted from the UVJ epithelium (containing SST) and vaginal epithelium (VGE) of SI and AI hens. Real time-polymerase chain reaction data showed a clear tissue region-specific effect on gene expression in the turkey hen oviduct, with much greater (P < 0.0001) expression in the UVJ compared with VGE region for avidin and AVR2 mRNA in both lines and for progesterone receptor mRNA in the Converter line. In contrast to real-time PCR data, in situ hybridization of SI and AI tissues showed that the presence of sperm increased avidin mRNA in the SST and UVJ surface epithelium in the Converter hens. Immunohistochemistry confirmed the presence of avidin protein in the epithelium of the UVJ in both lines; however, whereas avidin protein was localized in the SST of SI-Grade Maker hens, this protein was not detected in the SST of Converter hens. The upregulation of avidin and AVR2 mRNA within the sperm storage region indicates the involvement of avidin, and perhaps avidin analogs, in the sustained storage of sperm in the SST, possibly through the binding of biotin to avidin. The absence of avidin protein in the SST and VGE of Converter hens in the presence of increased mRNA may indicate a rapid turnover of protein.

Abstract
Today's livestock diversity originated from the wild ancestor species and was subsequently shaped through the processes of mutation, genetic drift, and natural and human selection. Only a subset of the diversity present in the ancestral species survives in the domestic counterparts. A 2007 report released by UN Food and Agriculture Organization 'The State of the World's Animal Genetic Resources', compiled from surveys conducted in 169 countries, found that nearly 70% of the world's remaining livestock breeds live in developing countries. The UN report was presented to more than 300 policy makers, scientists, breeders, and livestock keepers at the First International Technical Conference on Animal Genetic Resources, held in September 2007 in Interlaken, Switzerland. The conference aims were to adopt a global plan of action for conserving animal genetic resources as its main outcome. In this paper, the current and potential contributions of reproductive and molecular biotechnology are considered as tools of conserving rare breeds of livestock.

Abstract
Flow cytometric assays of viable boar sperm were developed to measure reactive oxygen species (ROS) formation (oxidization of hydroethidine to ethidium), membrane lipid peroxidation (oxidation of lipophilic probe C(11)-BODIPY(581/591)), and mitochondrial inner transmembrane potential (DeltaPsi(m); aggregation of mitochondrial probe JC-1) during hypothermic liquid storage and freeze-thawing of boar semen and to investigate relationships among ROS, motility, DeltaPsi(m), and ATP production. Basal ROS formation and membrane lipid peroxidation were low in viable sperm of both fresh and frozen-thawed semen, affecting < or =4%. Sperm in fresh, liquid-stored and frozen-thawed semen appeared to be equally susceptible to the activity ROS generators xanthine/xanthine oxidase, FeSO(4)/ascorbate, and hydrogen peroxide (H(2)O(2)). Of the ROS generators tested, FeSO(4)/ascorbate was specific for membrane lipid peroxidation, whereas menadione, xanthine/xanthine oxidase, and H(2)O(2) were specific for oxidization of hydroethidine. Menadione (30microM) and H(2)O(2) (300microM) decreased (P<0.05) motility by 90% during 60min of incubation. Menadione decreased (P<0.05) the incidence of sperm with high DeltaPsi(m) by 95% during 60min of the incubation, although ATP content was not decreased (P>0.05) until 120min. In contrast, H(2)O(2) did not affect DeltaPsi(m) or ATP at any time. The formation of ROS was not associated with any change in viability (90%) for either menadione or H(2)O(2) through 120min. Overall, the inhibitory affects of ROS on motility point to a mitochondrial-independent mechanism. The reduction in motility may have been due to an ROS-induced lesion in ATP utilization or in the contractile apparatus of the flagellum.

Abstract
The objective was to determine the effects of osmolality on the energy status of testicular spermatozoa of striped bass incubated in a TRIS free base-NaCl medium (pH 8) adjusted to either 300 (T300) or 600 mOsm/kg (T600) with NaCl. High mitochondrial inner transmembrane potential (DeltaPsim) was assessed (flow cytometry) with the mitochondrial probe 5, 5', 6, 6'-tetrachloro-1, 1', 3, 3'-tetraethylbenzimidazolyl- carbocyanine iodide (JC-1) and ATP was measured with a luciferin-luciferase assay. Spermatozoa maintained on ice were equally viable (>95% for T300 and T600) for up to 80 min, whereas sperm viability in artificial fresh water (FW) at 27 mOsm/kg decreased (P<0.05) to 67% after 5 min, with only 3.5% viability at 25 min. After 20 min of staining, more spermatozoa (P<0.05) maintained a high DeltaPsim in T300 than in T600 (80 and 50%, respectively). Sperm JC-1 aggregate (Jagg) fluorescence intensity was also greater (P<0.05) in T300 than in T600 (10 and 5 channel number). The Jagg fluorescence was a function of oxidative phosphorylation; the percentage of cells containing Jagg fluorescence decreased to 3% in the presence of carbonyl cyanide 3-chlorophenylhydrazone (CCCP), an uncoupler of cell respiration and oxidative phosphorylation. After incubation for 30 min in the absence of CCCP, sperm ATP concentration was greater (P<0.05) in T300 than in T600 (2.0 vs. 0.2 pmol/10(6) cells), but was below detectability in the presence of CCCP in either medium. In conclusion, we developed a unique approach to assess the energetic status of striped bass spermatozoa during storage and after activation, and concluded that the effects of osmolality must be considered in the design of activating and storage extenders to maintain striped bass sperm motility, viability, and fertility in vitro.

Abstract
Agricultural animal research has been immensely successful over the past century in developing technology and methodologies that have dramatically enhanced production efficiency of the beef, dairy, swine, poultry, sheep, and aquaculture industries. In the past two decades, molecular biology has changed the face of agricultural animal research, primarily in the arena of genomics and the relatively new offshoot areas of functional genomics, proteomics, transcriptomics, metabolomics and metagenomics. Publication of genetic and physical genome maps in the past 15 years has given rise to the possibility of being able finally to understand the molecular nature of the genetic component of phenotypic variation. While quantitative geneticists have been remarkably successful in improving production traits, genomic technology holds potential for being able to lead to more accurate and rapid animal improvement, especially for phenotypic traits that are difficult to measure.Recently, the agricultural research community has been able to capitalize on the infrastructure built by the human genome project by sequencing two of the major livestock genomes (Gallus domesticus and Bos Taurus). The 2005 calendar year is truly unprecedented in the history of agricultural animal research since draft genome sequences were completed for chickens and cattle. In addition, sequencing the swine and equine genome was initiated in early 2006. We now have in place a powerful toolbox for understanding the genetic variation underlying economically important and complex phenotypes. Over the past few years, new challenges have emerged for animal agriculture. Enhancements in production efficiency have not come without some negative side effects on animal well-being and longevity in production environments, including losses in reproductive efficiency, increased stress susceptibility, increased animal waste issues, and increased susceptibility to animal metabolic and infectious diseases. When considered in concert with societal concerns in the areas of natural resource conservation and protection, animal welfare, and food safety, it is clear that publicly supported agricultural research must be focused on enhancing the functionality and well-being of livestock and poultry in environmentally neutral production systems in the future. Realizing the great potential for animal genomics to address these and other issues, a workshop was convened by the U. S. Department of Agriculture (USDA) in Washington, DC in September of 2004. The workshop was entitled "Charting the Road Map for Long Term USDA Efforts in Agricultural Animal Genomics". This paper summarizes the proceedings of the workshop and the resulting recommendations. The need for a cohesive, comprehensive long-term plan for all of USDA's research efforts in animal genomics was evident at the workshop, requiring further integration of the efforts of the USDA's Cooperative State Research, Education, and Extension Service (CSREES) and the USDA's Agricultural Research Service (ARS) to achieve the greatest return on investment.

Abstract
The value of the ability to cryopreserve and store germplasm has long been recognized for indefinite preservation of genetic material, especially for at-risk populations. In contrast to domestic livestock species, cryogenic storage of poultry semen is not reliable enough for germplasm preservation. The relatively low fertilizing ability of frozen/thawed poultry sperm most likely results from physiological sensitivity to the cryogenic process coupled with the requirement for prolonged sperm functionality in the hen reproductive tract; however, the concept of defining these physiological challenges has been underemphasized. For example, alterations in membrane carbohydrate content and diminished energy production in frozen/thawed sperm have important implications for successful gamete interaction. Recent data suggests that both glycoconjugate content and adenosine triphosphate (ATP) generation are affected by cryopreservation. Moreover, susceptibility to the cryogenic process seems to vary among lines and strains of birds, as illustrated by line-specific differences in ATP concentrations of frozen/thawed sperm from pedigreed commercial layers. Research based on biochemical and molecular comparisons of sperm among lines may lead to identification of factors that influence the freezability of poultry semen.

Abstract
Semen cryopreservation is necessary for banking germplasm from critical poultry stocks. To date, glycerol is the most effective cryoprotectant for poultry sperm; however, the contraceptive effects of glycerol require a significant reduction of the cryoprotectant from thawed semen before artificial insemination (AI). The effectiveness of glycerol reduction by dialysis, Percoll density gradient centrifugation, or washing through 12% (wt/vol) Accudenz was evaluated by fertility trials with highly inbred chicken research lines and commercial turkey lines. Semen was extended 1:1 and then diluted with glycerolized extender to yield a final 11% (vol/vol) glycerol concentration. Glycerolized rooster semen was aliquoted for control, Accudenz centrifugation, and dialysis treatments. A total of 90 pure line and 85 F1 hybrid chicken hens were each inseminated with 100 x 10(6) sperm at 7-d intervals for 4 to 6 wk. All eggs from the glycerolized control semen treatments were infertile, and fertility rates from dialyzed semen decreased steadily from 26.4 to 0% within the first 4 wk for the pure lines. In contrast, fertility rates for Accudenz-processed semen increased from 17.9 to 37.17% during the first 4 wk. Similar fertility rates occurred with the F1 hybrid cross lines. For turkey fertility trials, the dialysis treatment was not used; glycerolized turkey semen was processed by Accudenz or Percoll centrifugation to reduce glycerol. A total of 36 hens were inseminated with 150 x 10(6) sperm at 7-d intervals for 6 wk. Similar to the chicken trials, fertility rates of Accudenz-processed semen steadily increased to 49.4% by the sixth week of insemination. The average fertility of Percoll-processed semen was only 19.1%. These data demonstrate that Accudenz centrifugation is an acceptable glycerol reduction method for nonfrozen poultry semen.

Abstract
Turkey sperm plasma membranes contain high levels of polyunsaturated fatty acids that are susceptible to lipid peroxidation during in vitro storage at 4 degrees C. Herein we assessed the degree of lipid peroxidation and fertility potential of semen liquid-stored for 24 h with the antioxidant vitamin E. Semen was collected weekly from 44 males and pooled as pairs (total = 22); the individuals in paired samples exhibited similar semen quality parameters. After initial semen evaluation, pooled samples were extended with Beltsville Poultry Semen Extender containing no supplement (control) or 10 or 40 microg/mL vitamin E and then stored at 4 degrees C with constant aeration for 24 h. Lipid peroxidation was determined by measuring malonaldehyde (MDA) in aliquots (50 x 10(6) sperm) of fresh (0 h) and stored (24 h) semen. Sperm mobility was also evaluated. A total of 176 hens (8 hens/tom pair; 4 hens/0 h, 4 hens/24 h) were inseminated (150 x 10(6) sperm) weekly for 6 wk, and fertility was determined after 7 d of incubation. Initial MDA values of the 22 tom pairs ranged from 0.928 to 1.36 uM. Males varied in production of MDA during in vitro storage, with most pairs exhibiting a threefold increase. Results indicated that supplemental vitamin E did not reduce lipid peroxidation during liquid storage. Not surprisingly, artificial insemination with stored semen (with much higher MDA values) yielded lower fertility rates than control regardless of the presence of vitamin E. These results demonstrate that lipid peroxidation is a significant factor affecting the fertility of stored turkey sperm and that methods to prevent or reduce lipid peroxidation remain to be elucidated.

Abstract
Formaldehyde oxime <--> nitrosomethane tautomerism, isomeric nitrone, and their common cations and anions are studied with Gaussian-2 theory using MP2(full)/6-31G geometries and with density functional theory using B3LYP/6-311+G**. Geometrical parameters, harmonic vibrational frequencies, relative stabilities, conformational stabilities, and ionization energies are compared with experimental gas-phase data when available. The formaldehyde oxime <--> nitrosomethane tautomerism is compared with the amide <--> imidol, imine <--> enamine, keto <--> enol, and nitro <--> aci-nitro tautomeric processes. Solvent effects are estimated by the self-consistent isodensity polarizable continuum model (SCIPCM). The influence of hydrogen bonding interactions with the solvent is addressed by including two water molecules. In the final evaluation, formaldehyde oxime is 15.8 kcal/mol more stable than nitrosomethane when the aqueous solvation correction of 3.8 kcal/mol is applied to the G2 energies. Unsolvated formaldehyde oxime is estimated to be 11.1 kcal/mol more stable than nitrone. The estimated gas-phase ionization energies (G2) are 362.5 kcal/mol for formaldehyde oxime, 350.6 kcal/mol for nitrosomethane, and 351.4 kcal/mol for nitrone.

Abstract
Limited reproductive data are available for any species of howler monkey, including those listed as threatened (Alouatta pigra) and endangered (A. palliata) by the Convention on International Trade in Endangered Species Status (CITES) report. The Southern black howler monkey (A. caraya) is being considered as a model species to develop assisted reproductive technology (ART) for vulnerable howler species. Specific objectives of this study were to evaluate the effect of 1) time of year on ejaculate quality and testosterone concentration, 2) age of male on ejaculate quality, and 3) seminal plasma on sperm longevity in vitro. Three adult (4.5 to 5 years) and 3 subadult (1.5 to 2.5 years) males were evaluated for a 1.5-year period. Semen samples were obtained by electroejaculation, and testosterone levels were monitored by fecal steroid metabolite radioimmunoassay. Males produced coagulum-free ejaculates throughout the year. Likewise, most (4/6) males exhibited constant testosterone levels (3.66 +/- 0.45 ng/g) during the year. Testosterone levels for the remaining 2 males, housed as a bachelor troop, were elevated (43 ng/g) during the months of May and June. Seminal characteristics were similar (P > .05) between age groups. Average semen volume was higher during the summer months (P < .05). Sperm concentrations were highly variable through the year and ranged from 7.0 x 10(6) sperm/mL to 583.0 x 10(6) sperm/mL. Percentages of motile sperm (73% +/- 2.3%) and forward progressive sperm motility (3.3 +/- 0.1), however, were consistent (P > .05) throughout the year. The average pH (8.9 +/- 0.1) and osmolality (356.7 +/- 26.1 mmol/kg) of raw semen also did not vary (P > .05) throughout the year. Ejaculates from subadult males, however, contained more (P < .05) morphologically abnormal spermatozoa than adult ejaculates. In addition, in vitro sperm longevity was poor (<2 hours) for subadult male samples, regardless of the presence or absence of seminal plasma (P > .05). For adult males, seminal plasma was detrimental to sperm longevity; however, spermatozoa survived more than 5 hours in vitro when seminal plasma was removed. Although subadult males produce semen, these ejaculates would not be ideal for further characterization of seminal traits or development of ART for other howler monkey species.

Abstract
The GnRH analogue deslorelin, in long-acting implants, was used in an attempt to temporarily control reproduction or aggression in wild carnivores in southern Africa and the USA. In the southern African study, 6 mg deslorelin was administered to cheetahs (eight females, four males), one female leopard and wild dogs (six females, one male) housed in groups, and 12 mg deslorelin was administered to two lionesses. None of the animals became pregnant after deslorelin administration apart from one wild dog that was mated at the initial treatment-induced oestrus. Two wild dogs and one lioness came into oestrus 12 and 18 months after deslorelin administration, respectively, thus demonstrating that the anti-fertility effects of deslorelin are reversible. Two lionesses and four cheetahs underwent oestrus without allowing mating 2-14 days after treatment. Simultaneous administration of progestins to three bitches and one lioness did not suppress oestrus. Male cheetahs had no spermatozoa on day 82 after treatment and did not impregnate two untreated females. Of three untreated female wild dogs housed with treated males, only the first female to enter oestrus (21 days after deslorelin administration) became pregnant. One month after treatment, plasma testosterone concentrations of male dogs were at basal values. In the USA study, three male sea otters that had been treated with 6 mg deslorelin ceased antagonistic behaviour and blood testosterone concentrations and size of the testes were still sharply reduced 24 months after treatment. Male red (n = 7) and grey (n = 5) wolves received 6 mg deslorelin in December 1998 but no effects on seasonal spermatogenesis and behaviour were observed. In a black-footed cat, sperm production, libido and aggressiveness decreased in response to treatment with 3 mg deslorelin and penile spines were not observed within 3 months after treatment, but were observed again 4-6 months later. Treatment of female red (n = 5) and grey (n = 5) wolves with deslorelin in December 1999 triggered preseason oestrus and mating, which were followed by one abortion and one successful pregnancy. Contraception was achieved in female Fennec foxes (n = 7) and two lionesses, which was observed in the foxes by an absence of increases in faecal progesterone concentrations. In two male bush dogs, administration of 3 mg deslorelin once or twice was insufficient to suppress reproductive function or behaviour.

Abstract
OBJECTIVE To investigate whether patient satisfaction with health is a distinct aspect of clinical or health status in a sample of patients with psoriatic arthritis (PsA). METHODS One hundred sixty-nine consecutive outpatients attending the University of Toronto PsA Clinic completed the Arthritis Impact Measurement Scales II (AIMS2), which includes both a global rating of patient satisfaction with health and a scale that assesses satisfaction with functioning in 12 health domains. Clinical, laboratory, and radiological assessments of function, pain, inflammation, and damage were also performed according to a standard protocol. RESULTS Logistic regression analysis indicated that the AIMS2 global ratings of patient satisfaction with health were not associated with traditional clinical measures of inflammation and damage, but were associated with American College of Rheumatology (ACR) functional class and number of fibromyalgia tender points. Patient satisfaction was also related to annual family income and use of retinoids or corticosteroids. Similarly, linear regression analysis showed that scores on the AIMS2 satisfaction scale were unrelated to traditional clinical measures of inflammation and damage, with the exception of total number of actively inflamed joints. ACR functional class, annual family income, and comorbidity were also related to scores on the satisfaction scale. CONCLUSION Patient satisfaction with health appears to be relatively independent of traditional clinical measures of physical functioning, pain, and disease status.

Abstract
B. bovis, an intraerythrocytic protozoal parasite, establishes chronic infections in cattle in part through rapid variation of the polymorphic, heterodimeric VESA1 protein on the infected erythrocyte surface and sequestration of mature parasites. We describe the characterization of the ves1 alpha gene encoding the VESA1a subunit, thus providing a description of a gene whose product is involved in rapid antigenic variation in a babesial parasite. This three-exon gene, a member of a multigene family (ves), encodes a polypeptide with no cleavable signal sequence, a single predicted transmembrane segment, and a cysteine/lysine-rich domain. Variation appears to involve creation and modification or loss of a novel, transcribed copy of the gene.

Abstract
Babesia bovis, an intraerythrocytic parasite of cattle, is sequestered in the host microvasculature, a behavior associated with cerebral and vascular complications of this disease. Despite the importance of this behavior to disease etiology, the underlying mechanisms have not yet been investigated. To study the components involved in sequestration, B. bovis parasites that induce adhesion of the infected erythrocytes (IRBCs) to bovine brain capillary endothelial cells (BBEC) in vitro were isolated. Two clonal lines, CD7(A+I+) and CE11(A+I-), were derived from a cytoadherent, monoclonal antibody 4D9.1G1-reactive parasite population. This antibody recognizes a variant, surface-exposed epitope of the variant erythrocyte surface antigen 1 (VESA1) of B. bovis IRBCs. Both clonal lines were cytoadhesive to BBEC and two other bovine endothelial cell lines but not to COS7 cells, FBK-4 cells, C32 melanoma cells, or bovine brain pericytes. By transmission electron microscopy, IRBCs were observed to bind to BBEC via the knobby protrusions on the IRBC surface, indicating involvement of components associated with these structures. Inhibition of protein export in intact, trypsinized IRBCs ablated both erythrocyte surface reexpression of parasite protein and cytoadhesion. IRBCs allowed to recover surface antigen expression regained the ability to bind endothelial cells, demonstrating that parasite protein export is required for cytoadhesion. We propose the use of this assay as an in vitro model to study the components involved in B. bovis cytoadherence and sequestration.

Abstract
Protein tyrosine phosphorylation is associated with sperm capacitation and the acrosome reaction in several mammalian species. Changes in phosphorylation of a 95-kDa protein in human, mouse, and domestic cat spermatozoa are known to be influenced by capacitation and exposure to zona pellucida (ZP) proteins. We previously reported diminished phosphorylation of 95- and 160-kDa proteins in spermatozoa from teratospermic cats, compared with normospermic domestic cats. To determine if these proteins and mechanisms are present in other species in the phenotypically diverse Felidae family, we examined the relationship between tyrosine-phosphorylated sperm proteins and sperm morphology in the leopard cat (approximately 65% normal sperm/ejaculate), tiger (approximately 65%), clouded leopard (approximately 15%), and cheetah (approximately 30%). Furthermore, we investigated the involvement of cyclic adenosine monophosphate (cAMP) in the regulation of sperm protein tyrosine phosphorylation. Specifically, we assessed the following: 1) presence of tyrosine-phosphorylated proteins in sperm extracts; 2) changes in protein tyrosine phosphorylation after sperm capacitation and swim-up separation; 3) impact of tyrosine kinase inhibition on leopard cat sperm protein phosphorylation and ZP penetration; and 4) involvement of a cAMP-dependent pathway in the regulation of protein tyrosine phosphorylation. Immunoblotting analysis with anti-phosphotyrosine antibody (PY20) indicated that a 95-kDa protein was present in all four species. Additional phosphorylated proteins were detected in the leopard cat (145- and 175-kDa proteins), tiger (185-kDa protein), clouded leopard (160- and 190-kDa proteins), and cheetah (115- and 155-kDa proteins). Sperm capacitation in vitro increased phosphorylation of one or more proteins in the leopard cat, tiger and clouded leopard, but not in the cheetah. Although swim-up separation increased the proportion of morphologically normal spermatozoa in the clouded leopard and cheetah, no changes were observed in phosphorylation of the 95-kDa sperm protein. Thus, phosphorylation of the 95-kDa protein appeared to be related to the condition of teratospermia. Exposing leopard cat spermatozoa to the tyrosine kinase inhibitor, tyrphostin, reduced (P < 0.05) phosphorylation of the 95- and 145-kDa proteins, as well as ZP penetration, without affecting sperm motility. Similarly, when spermatozoa were incubated in the presence of cAMP analogs or active and inactive stereoisomers of cAMP, phosphorylation of sperm proteins was either stimulated or inhibited. Together, these data suggest that protein tyrosine kinase mechanisms appear conserved within the family Felidae and are regulated by a cAMP/protein kinase A pathway.

Abstract
The apical portion of the Arabidopsis globular stage embryo gives rise to the cotyledons and the shoot apical meristem (SAM). The SHOOT MERISTEMLESS (STM) gene is required for SAM formation during embryogenesis and for SAM function throughout the lifetime of the plant. To more precisely define the development of molecular pattern in the apical portion of the embryo, and the role of the STM gene in the development of this pattern, we have examined AINTEGUMENTA (ANT), UNUSUAL FLORAL ORGANS (UFO) and CLAVATA1 (CLV1) expression in wild-type and stm mutant embryos. The transcripts of these genes mark subdomains within the apical portion of the embryo. Our results indicate that: (1) the molecular organization characteristic of the vegetative SAM is not present in the globular embryo but instead develops gradually during embryogenesis; (2) radial pattern exists in the apical portion of the embryo prior to and independent of STM with STM expression itself responding to radial information; (3) the embryonic SAM consists of central and peripheral subdomains that express different combinations of molecular markers and differ in their ultimate fates; and (4) STM activity is required for UFO expression, STM is required for maintenance but not onset of CLV1 expression and the pattern of ANT expression is independent of STM.
