Abstract
STUDY QUESTION What are the changes in serum concentration of total and cleaved anti-Muüllerian hormone (AMH) molecular forms and of androgens before and throughout pregnancy in women with and without polycystic ovary syndrome (PCOS) in a longitudinal follow-up investigation? SUMMARY ANSWER Serum levels of total and cleaved AMH are higher from preconception to the third trimester of pregnancy in women with PCOS as compared to controls, whereas testosterone and androstenedione levels are higher in women with PCOS than in control women before pregnancy and during the second and third trimester of pregnancy. WHAT IS KNOWN ALREADY Cross-sectional or partial longitudinal studies have shown higher AMH and androgen levels in pregnant women with PCOS as compared with non-PCOS women. To date, no complete longitudinal dynamic monitoring of the circulating forms of AMH and androgens from pre-conception to the third trimester of pregnancy have compared women with and without PCOS. STUDY DESIGN, SIZE, DURATION This systematic prospective quarterly longitudinal monocentric study was a comparative follow-up of 30 women with PCOS and 29 controls before and during pregnancy from April 2019 to July 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS Women aged 18-43 years with a pre-conception measurement of AMH were included during the first trimester of a singleton pregnancy. The PCOS group was defined according to the Rotterdam diagnostic criteria. The control group patients included in the study had normal ovarian reserves. Circulating total and cleaved AMH, and serum estradiol, LH, and androgen levels were measured during the first, second, and third trimester of pregnancy in all study participants. MAIN RESULTS AND THE ROLE OF CHANCE Before pregnancy, patients with PCOS had higher levels of AMH than controls. The total and cleaved AMH forms were significantly higher in women with PCOS than controls from pre-conception to the third trimester of pregnancy (all P < 0.001). Androgens (total testosterone and androstenedione) were higher in women with PCOS than controls from mid-pregnancy onwards. LIMITATIONS, REASONS FOR CAUTION Our control population was a population of infertile women with no ovarian problems but most of them had undergone ART treatments to achieve pregnancy. WIDER IMPLICATIONS OF THE FINDINGS These results strengthen the hypothesis that gestational hyperandrogenism as well as exposure to elevated AMH levels in utero could be driving forces predisposing female progeny to develop PCOS.

Abstract
Abstract
Study question
Are circulating levels of molecular forms of AMH throughout pregnancy still higher in women with PCOS than in controls?
Summary answer
AMH and its molecular forms decrease significantly throughout pregnancy, remaining higher in women with PCOS, without modification in the proportion of AMH molecular forms.
What is known already
AMH injection in late gestational mice causes a “PCOS” phenotype in the offspring’s, possibly via a gestational hyperandrogenism. AMH could therefore play a role in the heritability of PCOS in women. Circulating AMH exists in different molecular forms, cleaved (active) and uncleaved. In normal women, serum AMH decreases during pregnancy. In women with PCOS, cross-sectional or partial longitudinal studies have shown higher AMH levels in the second trimester of pregnancy and at the time of delivery in women with PCOS compared to controls. To date, no longitudinal dynamic monitoring of AMH throughout pregnancy in women with PCOS has been performed.
Study design, size, duration
Systematic prospective quarterly longitudinal monocentric comparative follow up of 30 women with PCOS and 29 controls before and during pregnancy from April 2019 to September 2021. To demonstrate a high effect size with 90% power and 5% first-species risk, it was necessary to include 23 subjects per arm. With a calculated loss of follow-up rate of 20%, 29 patients must be recruited per group.
Participants/materials, setting, methods
Women aged 18 to 43y, with a pre-conception dosage of AMH, were included during the first trimester of a singleton pregnancy. PCOS group was defined according to the modified Rotterdam criteria. In the control group, the patients had normal ovarian reserve. During the first, second and third trimester of pregnancy, all women were tested for serum AMH and its molecular forms with a Beckman automatic analyser, and for serum estradiol, LH and androgen levels.
Main results and the role of chance
Before pregnancy, patients with PCOS had higher levels of AMH (58.9 vs. 18.3pmol/L; p = <0.001), LH (5.9 vs. 3.3IU/L; p = 0.004) and total testosterone (TT) (0.35 vs. 0.29ng/ml; p = 0.019) than controls. Within each group, the levels of AMH and cleaved AMH were significantly lower in the third trimester than before pregnancy. The serum AMH level in the third trimester remained significantly higher in women with PCOS than in controls (18.4 vs. 6.5pmol/L; p = 0.002). At all times, the amount of cleaved AMH was higher in women with PCOS than in controls. The proportion of AMH molecular forms was not different between women with PCOS and controls and did not change throughout pregnancy. The LH level, mostly undetectable, was significantly lower in the third trimester than before pregnancy in both groups. In the first trimester, it remained higher in women with PCOS (0.6 vs 0.4IU/L; p = 0.018). In each group, the TT level was significantly higher in the third trimester than before pregnancy. TT level remained higher in women with PCOS than in control women in the first (0.76 vs 0.55ng/ml; p = 0.022) and second trimesters 0.82 vs. 0.61ng/ml; p = 0.013). In the third trimester, it was no longer significantly different (0.97 vs 0.64ng/ml; p = 0.069).
Limitations, reasons for caution
Only free testosterone is active, and only TT was measured. Additional SHBG and albumin measurements are needed. Our control population is a population of infertile women who have no ovarian problem but who have undergone, for most of them, ART treatments to obtain pregnancy with a possible impact on implantation.
Wider implications of the findings
Elevated serum AMH level could be instrumental in the modification of the in-utero androgenic environment that is believed to promote the transmission of the syndrome. The impact of AMH could be different depending on the clinical or metabolic phenotype of the patients and needs to be explored further.

Abstract
Introduction First episode psychosis (FEP) programs target the first 3-5 years after the first manifestation of a psychotic episode. Although follow-up results after 10-15 years are mixed, reported results of the first 5-10 years are promising in improving relapse prevention, functional outcomes and reducing mental health care costs, compared to treatment as usual. Objectives Our objective was to develop the first complex FEP program in Hungary. Methods Male and female inpatients, (age:17-40years), hospitalized due to a first psychotic episode and consenting to participate, were included, since 2019 October. Drug induced psychosis and organic background in the etiology of the psychotic episode were excluded. Duration of the program is 2-3 years, based on the individual needs of the patients. The program provides detailed clinical and neuropsychological examinations, MRI, pharmacotherapy, various psychosocial interventions, and support group for relatives. Results Twenty-eight patients [15 male,13 female, mean age=22,4 (18-40)years] were included. The program has been repeatedly limited by COVID-19 pandemic. Psychiatric control, pharmacotherapy, psychoeducation and supportive therapy, however could be continously provided via telepsychiatry, even during the lockdown. During the first 2 years, 90% of the patients remained in treatment, showed good compliance with pharmacotherapy; 10% of the patients were rehospitalized due to relapse. In the presentation, besides clinical experiences, preliminary clinical outcome data will also be presented. Conclusions The first complex FEP program in Hungary, although limited repeatedly by the pandemic, show promising clinical results with low relapse rates and high level of adherence to therapy in the first 2 years after a first psychotic episode.

Abstract
Toxic effects of nanoparticles on female reproductive health have been documented but the underlying mechanisms still need to be clarified. Here, we investigated the effect of carbon black nanoparticles (CB NPs) on the pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are key regulators of gonadal gametogenesis and steroidogenesis. To that purpose, we subjected adult female mice to a weekly non-surgical intratracheal administration of CB NPs at an occupationally relevant dose over 4 weeks. We also analyzed the effects of CB NPs in vitro, using both primary cultures of pituitary cells and the LβT2 gonadotrope cell line. We report here that exposure to CB NPs does not disrupt estrous cyclicity but increases both circulating FSH levels and pituitary FSH β-subunit gene (Fshb) expression in female mice without altering circulating LH levels. Similarly, treatment of anterior pituitary or gonadotrope LβT2 cells with increasing concentrations of CB NPs dose-dependently up-regulates FSH but not LH gene expression or release. Moreover, CB NPs enhance the stimulatory effect of GnRH on Fshb expression in LβT2 cells without interfering with LH regulation. We provide evidence that CB NPs are internalized by LβT2 cells and rapidly activate the cAMP/PKA pathway. We further show that pharmacological inhibition of PKA significantly attenuates the stimulatory effect of CB NPs on Fshb expression. Altogether, our study demonstrates that exposure to CB NPs alters FSH but not LH expression and may thus lead to gonadotropin imbalance.

Abstract
Background Data from interventional studies suggest that a peritoneal flap after pelvic lymph node dissection (LND) during laparoscopic, robotic-assisted radical prostatectomy (RARP) may reduce the rate of symptomatic lymphoceles in transperitoneal approach. However, most of these studies are not conducted in a randomized controlled fashion, thus limiting their scientific value. A recent prospective, randomized, controlled trial (RCT) did not show superiority of a peritoneal flap while further trials are lacking. Therefore, the aim of the presented RCT will be to show that creating a peritoneal flap decreases the rate of symptomatic lymphoceles compared to the current standard procedure without creation of a flap. Methods/design PELYCAN is a parallel-group, patient- and assessor-blinded, phase III, adaptive randomized controlled superiority trial. Men with histologically confirmed prostate cancer who undergo transperitoneal RARP with pelvic LND will be randomly assigned in a 1:1 ratio to two groups—either with creating a peritoneal flap (PELYCAN) or without creating a peritoneal flap (control). Sample size calculation yielded a sample size of 300 with a planned interim analysis after 120 patients, which will be performed by an independent statistician. This provides a possibility for early stopping or sample size recalculation. Patients will be stratified for contributing factors for the development of postoperative lymphoceles. The primary outcome measure will be the rate of symptomatic lymphoceles in both groups within 6 months postoperatively. Patients and assessors will be blinded for the intervention until the end of the follow-up period of 6 months. The surgeon will be informed about the randomization result after performance of vesicourethral anastomosis. Secondary outcome measures include asymptomatic lymphoceles at the time of discharge and within 6 months of follow-up, postoperative complications, mortality, re-admission rate, and quality of life assessed by the EORTC QLQ-C30 questionnaire. Discussion The PELYCAN study is designed to assess whether the application of a peritoneal flap during RARP reduces the rate of symptomatic lymphoceles, as compared with the standard operation technique. In case of superiority of the intervention, this peritoneal flap may be suggested as a new standard of care. Trial registration German Clinical Trials Register DRKS00016794.

Abstract
Foot pain is a frequent cause of lameness in horses and can involve multiple structures within the hoof. The T-ligament (an anatomical structure connecting the synovium of the distal interphalangeal joint, the digital flexor tendon sheath and the navicular bursa) is poorly described. Five pairs of equine cadaver distal forelimbs were collected from a slaughterhouse. Sagittal sections (medial, middle and lateral) were obtained and processed with Haematoxylin Eosin Safran, Unna's Orcein, and Picrosirius red stains. Histological assessment revealed that the T-ligament was covered by the surrounding synovia of the distal interphalangeal joint, the digital flexor tendon sheath and the navicular bursa. Its collagen content was lower (30.01%±10.15) than that of the collateral sesamoidean ligament (89.48%±5.8; P = .0008) and the middle phalanx (85.72%±3.67; P = .0008). Under polarized light microscopy, it showed a slight heterogeneous pattern of birefringence, with angle-related changes. Elastic fibres were more numerous (21.76%±8.72) than in the collateral sesamoidean ligament (0.28%±0.45), or deep digital flexor tendon (0.04%±0.02); and were more densely packed. Mean cell count was higher for the T-ligament than for other tissues (P = .0007). Blood vessels were identified in the T-ligament and were penetrating the deep digital flexor tendon (8/10 limbs, 5/5 horses). In conclusion, the T-ligament looked like a vinculum for the deep digital flexor tendon, with a central elastic core, surrounding loose connective tissue and blood vessels. It is not a ligament. Its clinical relevance still needs to be determined.

Abstract
INTRODUCTION Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD. METHOD All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD. RESULTS A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up. CONCLUSION During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Abstract
AbstractBackgroundThe objective of the present study was to examine the association of insight into the illness with demographic variables and symptomatology in a sample of 1213 patients with schizophrenia.MethodData were collected with the Psychosis Evaluation tool for Common use by Caregivers (PECC), a semi-structured interview evaluating five symptom domains of schizophrenia and the insight items ‘awareness of having a mental disorder’ and ‘attributing symptoms to a mental disorder’.ResultsInsight was positively associated with educational level and inversely with overall symptom severity, and the positive, negative, excitatory and cognitive symptom domains. At symptom level, the items ‘delusions’, ‘grandiosity’, ‘poor rapport’, ‘social withdrawal’ and ‘guilt feelings’ showed the strongest associations with both insight items. Overall, correlations between insight and symptomatology were modest, explaining less than 30% of the variance in insight.ConclusionLack of insight in schizophrenia is partially explained by clinical symptoms and demographic measures.

Abstract
BACKGROUND Low-grade serous ovarian carcinoma (LGSOC) is a rare disease that accounts for 5% of all ovarian cancers and requires surgical complete debulking. To date, the prognostic value of pelvic and paraaortic lymphadenectomy remains unclear in this population. PATIENTS AND METHODS This retrospective cohort of patients with a diagnosis of LGSOC was registered in the Tumeurs Malignes Rares Gynécologiques national network, between January 2000 and July 2017, at 25 centers. All LGSOC were confirmed after pathological review and operated by primary debulking surgery (PDS) or interval debulking surgery after neoadjuvant chemotherapy (NACT-IDS). Primary endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS A total of 126 patients were included, 86.1% were stage III/IV, and 74.6% underwent lymph node dissection (LND). According to the Completeness of Cancer Resection (CCR) score, 83.7% had complete resection. Median OS was 130 months, and median PFS was 41 months. Pelvic and paraaortic LND had no significant impact on OS (p = 0.78) or DFS (p = 0.93), and this was confirmed in subgroups (advanced stages FIGO III/IV, CCR score 0/1 or 2/3, and timing of surgery PDS or NACT-IDS). Histological positive paraaortic lymph nodes had a significant negative impact on PFS in the whole population (HR 2.21, 1.18-4.39, p = 0.02) and in the CC0/CC1 population (HR, 2.28, 1.13-4.59, p = 0.02). CONCLUSIONS Systematic pelvic and paraaortic LND in patients with LGSOC improved neither overall nor PFS. A prospective trial would be necessary to validate these results but would be difficult to conduct due to the rarity of this disease.

Abstract
UNLABELLED We conducted a qualitative study with French men and women in order to provide insight into individuals' experiences, behaviors, and perceptions about osteoporosis (OP) and OP care. The data showed that both sexes, but especially men, were unfamiliar with OP, did not always feel concerned, and mistrusted pharmacological treatments. INTRODUCTION To engage actively in osteoporosis (OP) prevention, people need to have basic knowledge about the disease. The aim of this qualitative study was to explore knowledge and representations of OP care and prevention among both men and women. METHODS Focus groups were conducted in the Rhône-Alpes Region, France, with women aged 50-85 years and men aged 60-85 years, with or without a history of fragility fracture and/or an OP diagnosis (respectively referred to as "aware" or "unaware"). A total of 45 women (23 "aware" and 22 "unaware" in 5 and 4 focus groups, respectively) and 53 men (19 "aware" and 34 "unaware" in 3 and 4 focus groups, respectively) were included. A thematic analysis of transcripts was performed to explore knowledge and representations about OP, risk factors, prevention, and treatment. RESULTS The data showed that both sexes, but especially men, had limited knowledge of OP and considered it as a natural aging process not related to fragility fractures. They generally did not feel concerned by OP and no important difference was observed between "aware" and "unaware" patients. Women expressed their fear of the disease, associated with aging and the end of life, while men considered it to be a women's disease only. Both sexes were aware of OP risk factors, but were suspicious towards treatments because of the associated side effects. CONCLUSION Understanding people's representation of OP might help to provide patients with relevant information in order to optimize their preventive behavior and decrease the burden of the disease.

Abstract
Limited data exist regarding patient-reported outcomes and quality of life (QOL) experienced by patients with Barrett's esophagus (BE) referred for endoscopic eradication therapy (EET). Specifically, the impact of grade of dysplasia has not been explored. The purpose of this study is to measure patient-reported symptoms and QOL and identify factors associated with poor QOL in BE patients referred for EET. This was a prospective multicenter study conducted from January 2015 to October 2017, which included patients with BE referred for EET. Participants completed a set of validated questionnaires to measure QOL, symptom severity, and psychosocial factors. The primary outcome was poor QOL defined by a PROMIS score >12. Multivariable logistic regression analysis was performed to identify factors associated with poor QOL. In total, 193 patients participated (mean age 64.6 years, BE length 5.5 cm, 82% males, 92% Caucasians) with poor QOL reported in 104 (53.9%) participants. On univariate analysis, patients with poor QOL had lower use of twice daily proton pump inhibitor use (61.5% vs. 86.5%, P = 0.03), shorter disease duration (4.9 vs. 5.9 years, P = 0.04) and progressive increase in grade of dysplasia (high-grade dysplasia: 68.8% vs. 31.3%, esophageal adenocarcinoma: 75.5% vs. 24.5%, P < 0.001). Multivariate analysis demonstrated that high-grade dysplasia was independently associated with poor QOL (OR: 5.57, 95% CI: 1.05, 29.5, P = 0.04). In summary, poor QOL is experienced by the majority of patients with BE referred for EET and the degree of dysplasia was independently associated with poor QOL, which emphasizes the need to incorporate patient-centered outcomes when studying treatment of BE-related dysplasia.

Abstract
Reproductive function is under the control of the neurohormone GnRH, which activates a G-protein-coupled receptor (GnRHR) expressed in pituitary gonadotrope cells. GnRHR activates a complex signaling network to regulate synthesis and secretion of the two gonadotropin hormones, luteinizing hormone and follicle-stimulating hormone, both regulating gametogenesis and steroidogenesis in gonads. Recently, in an attempt to identify the mechanisms underlying GnRHR signaling plasticity, we identified the first interacting partner of GnRHR, the proto-oncogene SET. We showed that SET binds to intracellular domains of GnRHR to enhance its coupling to cAMP pathway in αT3-1 gonadotrope cells. Here, we demonstrate that SET protein is rapidly regulated by GnRH, which increases SET phosphorylation state and decreases dose-dependently SET protein level. Our results highlight a post-translational regulation of SET protein involving the proteasome pathway. We determined that SET phosphorylation upon GnRH stimulation is mediated by PKC and that PKC mediates GnRH-induced SET down-regulation. Phosphorylation on serine 9 targets SET for degradation into the proteasome. Furthermore, a non-phosphorylatable SET mutant on serine 9 is resistant to GnRH-induced down-regulation. Altogether, these data suggest that GnRH-induced SET phosphorylation on serine 9 mediates SET protein down-regulation through the proteasome pathway. Noteworthy, SET down-regulation was also observed in response to pulsatile GnRH stimulation in LβT2 gonadotrope cells as well as in vivo in prepubertal female mice supporting its physiological relevance. In conclusion, this study highlights a regulation of SET protein by the neurohormone GnRH and identifies some of the mechanisms involved.

Abstract
OBJECTIVES Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period. METHODS Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification. RESULTS 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/105 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/105 (+126%; P<0.001) and for UC, from 1.6 to 4.1/105 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC. CONCLUSIONS In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Abstract
BACKGROUND AND AIMS Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome. METHODS Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected. RESULTS In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups. CONCLUSIONS Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

Abstract
Secretion of 17-β-estradiol (E2) by human granulosa cells can be disrupted by various environmental toxicants. In the current study, we investigated whether carbon black nanoparticles (CB NPs) affect the steroidogenic activity of cultured human granulosa cells. The human granulosa cell line KGN and granulosa cells from patients undergoing in vitro fertilization were treated with increasing concentrations of CB NPs (1 to 100 µg/mL) together or not with follicle-stimulating hormone (FSH). We observed that CB NPs are internalized in KGN cells without affecting cell viability. CB NPs could be localized in the cytoplasm, within mitochondria and in association with the outer face of the endoplasmic reticulum membrane. In both cell types, CB NPs reduced in a dose-dependent manner the activity of aromatase enzyme, as reflected by a decrease in E2 secretion. A significant decrease was observed in response to CB NPs concentrations from 25 and 50 µg/mL in KGN cell line and primary cultures, respectively. Furthermore, CB NPs decreased aromatase protein levels in both cells and reduced aromatase transcript levels in KGN cells. CB NPs rapidly activated extracellular signal-regulated kinase 1 and 2 in KGN cells and pharmacological inhibition of this signaling pathway using PD 98059 significantly attenuated the inhibitory effects of CB NPs on CYP19A1 gene expression and aromatase activity. CB NPs also inhibited the stimulatory effect of FSH on aromatase expression and activity. Altogether, our study on cultured ovarian granulosa cells reveals that CB NPs decrease estrogens production and highlights possible detrimental effect of these common NPs on female reproductive health.

Abstract
AIM The purpose of this study was to investigate intraoperative iris behavior during some phacoemulsification maneuvers in rabbits treated with tamsulosin or finasteride. MATERIAL AND METHOD An experimental study was conducted on 26 Metis male rabbits aged 1.5 - 2 years, body weight between 3.4 and 5.6 kg, divided into three groups: Group 1 - Control, 6 rabbits; Group 2 - tamsulosin, 10 rabbits; Group 3 - finasteride, 10 rabbits. Dose calculation was performed according to body surface area ratio man/rabbit, taking into account the median lethal dose LD50. Surgery study in rabbits was done over two days by the same specialist using an adapted protocol. He was not informed before or during surgeries which group the animal belonged to, the order being random with a quasi-uniform distribution. Valid results for a modified iris behavior were obtained from two steps of the procedure (cannula irrigation maneuver and irrigation-aspiration). The iris billowing was graded from 0 to 3, according to severity. RESULTS The risk of intraoperative iris billowing was higher in rabbits included in tamsulosin group [OR=8.33 (CI 95% 0.63-110.09)], but insignificant statistically compare with control group (p= 0.13). In rabbits treated with finasteride the risk of intraoperative iris billowing is increased compared with those without treatment [OR=11.6 (CI 95% 0.92-147.6)], but insignificant statistically (p= 0.11). CONCLUSION In our research, we showed an increased risk of intraoperative iris billowing in rabbits treated with finasteride, almost similar with those obtained in rabbits treated with tamsulosin. Further experimental or clinical studies to confirm the role of finasteride in the etiology of intraoperative floppy iris syndrome in humans are needed. Hippokratia 2015, 19 (1): 20-24.

Abstract
Reactor design considerations are crucial aspects of dark fermentative hydrogen production. During the last decades, many types of reactors have been developed and used in order to drive biohydrogen technology towards practicality and economical-feasibility. In general, the ultimate aim is to improve the key features of the process, namely the H2 yields and generation rates. Among the various configurations, the traditional, completely stirred tank reactors (CSTRs) are still the most routinely employed ones. However, due to their limitations, there is a progress to develop more reliable alternatives. One of the research directions points to systems combining membranes, which are called as anaerobic membrane bioreactors (AnMBRs). The aim of this paper is to summarize and highlight the recent biohydrogen related work done on AnMBRs and moreover to evaluate their performances and potentials in comparison with their conventional CSTR counterparts.

Abstract
Reproductive function is highly dependent on nutritional input. We recently provided evidence that the unsaturated ω6 fatty acid (FA), linoleic acid (linoleic), interferes with transcription and secretion of the gonadotropin LH, highlighting the existence of a lipid sensing in pituitary gonadotropes. Here, we show, using a combination of in vivo and in vitro models, that linoleic differentially regulates Lhb and Fshb expression. Central exposure of rats to linoleic over 7 days was associated with increase of Lhb but not Fshb transcript levels. Consistently, exposure of rat pituitary cells or LβT2 cells to linoleic increased Lhb, whereas it dramatically decreased Fshb transcript levels without affecting its stability. This effect was also induced by ω9 and ω3-polyunsaturated FA but not by saturated palmitic acid. Analysis of the underlying mechanisms in LβT2 cells using small interfering RNA revealed that early growth response protein 1 mediates linoleic stimulation of Lhb expression. Furthermore, we demonstrated that linoleic counteracts activin and bone morphogenetic protein-2 stimulation of Fshb expression. Using Western blotting and Smad-responsive reporter gene assays, linoleic was shown to decrease basal Smad2/3 phosphorylation levels as well as activin- and bone morphogenetic protein-2-dependent activation of Smad, uncovering a new FA-sensitive signaling cascade. Finally, the protein phosphatase magnesium-dependent 1A was shown to mediate linoleic inhibition of basal Smad phosphorylation and Fshb expression, identifying protein phosphatase magnesium-dependent 1A as a new target of FA in gonadotropes. Altogether, this study provides a novel mechanism by which FAs target gene expression and underlines the relevant role of pituitary gonadotropes in mediating the effects of nutritional FA on reproductive function.

Abstract
Polycyclic aromatic hydrocarbon (PAH) concentrations and N, C stable isotope signatures were determined in mosses Hypnum cupressiforme Hedw. from 61 sites of 3 European regions: Île-de-France (France); Navarra (Spain); the Swiss Plateau and Basel area (Switzerland). Total PAH concentrations of 100-700 ng g(-1), as well as δ(13)C values of -32 to -29‰ and δ(15)N values of -11 to -3‰ were measured. Pearson correlation tests revealed opposite trends between high molecular weight PAH (4-6 aromatic rings) content and δ(13)C values. Partial Least Square regressions explained the very significant correlations (r > 0.91, p < 0.001) between high molecular weight PAH concentrations by local urban land use (<10 km) and environmental factors such as elevation and pluviometry. Finally, specific correlations between heavy metal and PAH concentrations were attributed to industrial emissions in Switzerland and road traffic emissions in Spain.

Abstract
Polymorphism in the plant eukaryotic translation initiation factor 4E (eIF4E) and potyvirus genome-linked protein (VPg) determine, in many cases, the outcome of the confrontation between these two organisms: compatibility (i.e. infection of the plant by the virus) or incompatibility (i.e. resistance of the plant to the virus). The two interacting proteins eIF4E and VPg show strikingly similar evolution patterns. Most codon positions in their coding sequences are highly constrained for nonsynonymous substitutions but a small number shows evidence for positive selection. Several of these latter positions were shown to be functionally important, conferring resistance to the host or pathogenicity to the virus. Determining the mutational pathways involved in pepper eIF4E diversification revealed a link between an increase of the pepper resistance spectrum towards a panel of potyvirus species and an increase of durability of the resistance towards Potato virus Y. This relationship questions the interest of using more generally the spectrum of action of a plant resistance gene as a predictor of its durability potential.

Abstract
In mammals, the receptor of the neuropeptide gonadotropin-releasing hormone (GnRHR) is unique among the G protein-coupled receptor (GPCR) family because it lacks the carboxyl-terminal tail involved in GPCR desensitization. Therefore, mechanisms involved in the regulation of GnRHR signaling are currently poorly known. Here, using immunoprecipitation and GST pull-down experiments, we demonstrated that SET interacts with GnRHR and targets the first and third intracellular loops. We delineated, by site-directed mutagenesis, SET binding sites to the basic amino acids (66)KRKK(69) and (246)RK(247), located next to sequences required for receptor signaling. The impact of SET on GnRHR signaling was assessed by decreasing endogenous expression of SET with siRNA in gonadotrope cells. Using cAMP and calcium biosensors in gonadotrope living cells, we showed that SET knockdown specifically decreases GnRHR-mediated mobilization of intracellular cAMP, whereas it increases its intracellular calcium signaling. This suggests that SET influences signal transfer between GnRHR and G proteins to enhance GnRHR signaling to cAMP. Accordingly, complexing endogenous SET by introduction of the first intracellular loop of GnRHR in αT3-1 cells significantly reduced GnRHR activation of the cAMP pathway. Furthermore, decreasing SET expression prevented cAMP-mediated GnRH stimulation of Gnrhr promoter activity, highlighting a role of SET in gonadotropin-releasing hormone regulation of gene expression. In conclusion, we identified SET as the first direct interacting partner of mammalian GnRHR and showed that SET contributes to a switch of GnRHR signaling toward the cAMP pathway.
