Abstract
Study question
What is the impact of the cancer treatment received prior to TTF and the disease on spermatogonia quantity in testicular tissue from (pre)pubertal boys?
Summary answer
A decrease in spermatogonia number was observed in testicular tissue after cancer treatment when cyclophosphamide equivalente dose (CED) is above 4000 mg/m2.
What is known already
The improved survival rates associated with the development of sperm and testicular tissue freezing (TTF) renders difficult not to offer fertility preservation to children or adolescents before cancer. Several studies exploring cancer patients have examined the number of spermatogonia per seminiferous tubular cross-section (S/T) or tubular fertility index (TFI, percentage of tubular cross-sections containing spermatogonia) in testicular biopsies. All studies, demonstrated that the S/T and TFI always decreased after the introduction of chemotherapy and more specifically in case of highly gonadotoxic risk such as alkylating agents.
Study design, size, duration
Testicular tissue samples from 79 (pre)pubertal boys diagnosed with cancer (ranging from 6 month to 16 years of age) were cryopreserved between May 2009 and June 2014. Medical diagnosis and previous chemotherapy exposure were recorded. We examined histological sections of (pre)pubertal testicular tissue to elucidate whether chemotherapy, doses or primary diagnosis affects the quality of testicular tissue.
Participants/materials, setting, methods
(Pre)pubertal boys with cancer diagnosis who benefitted from TTF prior to conditioning treatment for hematopoietic stem cell transplantation. All the patients included had previously received chemotherapy with moderate risk for future fertility. We have selected patients for whom data on chemotherapy received were complete. The quantity of spermatogonia and quality of testicular tissue were assessed by both morphological and immunohistochemical analysis.
Main results and the role of chance
The main finding was a significant reduction in spermatogonial cell counts in boys treated with alkylating agents. The mean S/T values in boys exposed to alkylating agents was significantly lower than in a group exposed to non-alkylating agents (p = 0.018). In contrast, no difference was observed for patients treated with carboplatin as the only alkylating agent compared to the group of patients exposed to non-alkylating agents. We observed an increase of S/T with age in the group of patients who did not receive alkylating agents and a decrease of S/T with age when patients received alkylating agents included in the CED formula (r = 0.6166, p = 0.0434; r= -0.3759, p = 0.0036, respectively). The TFI and S/T were decreased in the group of patients who received vincristine (p = 0.0049; p < 0.0001, respectively), but the CED was also significantly increased (p < 0.0001). Multivariate analysis, adjusted for CED, showed the persistence of a decrease in TFI correlated with vincristine administration (-0.5 [-0.96; 0.09], p = 0.02).
Limitations, reasons for caution
This is a descriptive study of testicular tissues obtained from patients who were at risk of infertility. Spermatognia functionanlity could not be tested by transplantation due limited sample size.
Wider implications of the findings
This study summarizes spermatogonia quantity and quality of testicular tissue of (pre)pubertal boys after potentially sterilizing treatments. We confirmed a negative correlation between the cumulative exposure to alkylating agents and the spermatogonial quantity. For patients in whom fertility preservation is indicated, TTF should be performed before initiation of alkylating agents.

Abstract
After extensive studies of 1D and 2D skeletal carbo-mers based on C8 π-conjugating dialkynylbutatriene units (DABs: ∼C≡C-(R)C=C=C=C(R)-C≡C∼) bridging sp or sp2 centers in carbo-butene, carbo-xylylene or carbo-benzene derivatives, 3D versions are envisaged through carbo-barrelenes and partially reduced derivatives thereof where two or three DAB blades span a bridge between sp3 carbinol vertices or ether thereof. For R=Ph, stable representatives were synthesized through a pivotal [6]pericyclynedione, and extensively characterized by spectroscopic, electrochemical and crystallographic methods. Density functional theory calculations allow detailed analysis of structural and electronic features of the 7 Å high C26 barrel-shaped molecules, and show that they can behave as cages for ionic species. Beyond aesthetical concerns, the results could open prospects of applications in host-guest supramolecular chemistry and single molecule charge transport.

Abstract
Dendrogenin A (DDA) is a mammalian cholesterol metabolite that displays potent antitumor properties on acute myeloid leukemia (AML). DDA triggers lethal autophagy in cancer cells through a biased activation of the oxysterol receptor LXRβ, and the inhibition of a sterol isomerase. We hypothesize that DDA could potentiate the activity of an anticancer drug acting through a different molecular mechanism, and conducted in vitro and in vivo combination tests on AML cell lines and patient primary tumors. We report here results from tests combining DDA with antimetabolite cytarabine (Ara-C), one of the main drugs used for AML treatment worldwide. We demonstrated that DDA potentiated and sensitized AML cells, including primary patient samples, to Ara-C in vitro and in vivo. Mechanistic studies revealed that this sensitization was LXRβ-dependent and was due to the activation of lethal autophagy. This study demonstrates a positive in vitro and in vivo interaction between DDA and Ara-C, and supports the clinical evaluation of DDA in combination with Ara-C for the treatment of AML.

Abstract
BACKGROUND Infertility is an important side effect of treatments used for cancer and other non-malignant conditions in males. This may be due to the loss of spermatogonial stem cells (SSCs) and/or altered functionality of testicular somatic cells (e.g. Sertoli cells, Leydig cells). Whereas sperm cryopreservation is the first-line procedure to preserve fertility in post-pubertal males, this option does not exist for prepubertal boys. For patients unable to produce sperm and at high risk of losing their fertility, testicular tissue freezing is now proposed as an alternative experimental option to safeguard their fertility. OBJECTIVE AND RATIONALE With this review, we aim to provide an update on clinical practices and experimental methods, as well as to describe patient management inclusion strategies used to preserve and restore the fertility of prepubertal boys at high risk of fertility loss. SEARCH METHODS Based on the expertise of the participating centres and a literature search of the progress in clinical practices, patient management strategies and experimental methods used to preserve and restore the fertility of prepubertal boys at high risk of fertility loss were identified. In addition, a survey was conducted amongst European and North American centres/networks that have published papers on their testicular tissue banking activity. OUTCOMES Since the first publication on murine SSC transplantation in 1994, remarkable progress has been made towards clinical application: cryopreservation protocols for testicular tissue have been developed in animal models and are now offered to patients in clinics as a still experimental procedure. Transplantation methods have been adapted for human testis, and the efficiency and safety of the technique are being evaluated in mouse and primate models. However, important practical, medical and ethical issues must be resolved before fertility restoration can be applied in the clinic.Since the previous survey conducted in 2012, the implementation of testicular tissue cryopreservation as a means to preserve the fertility of prepubertal boys has increased. Data have been collected from 24 co-ordinating centres worldwide, which are actively offering testis tissue cryobanking to safeguard the future fertility of boys. More than 1033 young patients (age range 3 months to 18 years) have already undergone testicular tissue retrieval and storage for fertility preservation. LIMITATIONS REASONS FOR CAUTION The review does not include the data of all reproductive centres worldwide. Other centres might be offering testicular tissue cryopreservation. Therefore, the numbers might be not representative for the entire field in reproductive medicine and biology worldwide. The key ethical issue regarding fertility preservation in prepubertal boys remains the experimental nature of the intervention. WIDER IMPLICATIONS The revised procedures can be implemented by the multi-disciplinary teams offering and/or developing treatment strategies to preserve the fertility of prepubertal boys who have a high risk of fertility loss. STUDY FUNDING/COMPETING INTERESTS The work was funded by ESHRE. None of the authors has a conflict of interest.

Abstract
Dendrogenin A (DDA) is a newly-discovered steroidal alkaloid, which remains to date the first ever found in mammals. DDA is a cholesterol metabolites that induces cancer cell differentiation and death in vitro and in vivo, and thus behave like a tumor suppressor metabolite. Preliminary studies performed on 10 patients with estrogen receptor positive breast cancers (ER(+)BC) showed a strong decrease in DDA levels between normal matched tissue and tumors. This suggests that a deregulation on DDA metabolism is associated with breast carcinogenesis. To further investigate DDA metabolism on large cohorts of patients we have developed an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS) procedure for the quantification of DDA in liquid and in solid tissues. This method enabled the identification of DDA analogues such as its geometric isomer C17 and dendrogenin B (C26) in human samples showing that other 5,6α-epoxycholesterol conjugation products with biogenic amines exist as endogenous metabolites . We report here the first complete method of quantification of DDA in liquid and solid tissues using hydrophilic interaction liquid chromatography (HILIC). Two different methods of extraction using either a Bligh and Dyer organic extraction or protein precipitation were successfully applied to quantify DDA in solid and liquid tissues. The protein precipitation method was the fastest. The fact that this method is automatable opens up possibilities to study DDA metabolism in large cohorts of patients.

Abstract
Dendrogenin A (DDA) is a tumor suppressor mammalian cholesterol-derived metabolite and a new class of ligand of the Liver X receptor (LXR), which displays tumor cell differentiation. In human MCF7 breast adenocarcinoma cells, DDA-induced cell differentiation was associated with an increased accumulation of neutral lipids and proteins found in milk indicating that DDA re-activates some functions of lactating cells. Active iodide transport occurs in the normal lactating mammary cells through the sodium/iodide symporter (NIS) and iodide (I) is secreted into milk to be used by the nursing newborn for thyroid hormones biosynthesis. In the present study, we assessed whether DDA may induce other characteristic of lactating cells such as NIS expression and iodine uptake in MCF7 breast cancer cells and extended this study to the papillary B-CPAP and undifferentiated anaplastic 8505c thyroid cancer cells. Moreover, we evaluated DDA impact on the expression of thyroid specific proteins involved in thyroid hormone biogenesis. We report here that DDA induces NIS expression in MCF7 cells and significantly increases the uptake of 131-I by acting through the LXR. In addition, DDA induces phenotypic, molecular and functional characteristics of redifferentiation in the two human thyroid carcinoma cell lines and the uptake of 131-I in the undifferentiated 8505c cells was associated with a strong expression of all the specific proteins involved in thyroid hormone biosynthesis, TSH receptor, thyroperoxidase and thyroglobulin. 131-I incorporation in the 8505c cells was stimulated by DDA as well as by the synthetic LXR ligand, GW3965. Together these data show that the re-differentiation of breast and thyroid cancer cells by DDA, is associated with the recovery of functional NIS expression and involves an LXR-dependent mechanism. These results open new avenues of research for the diagnosis of thyroid cancers as well as the development of new therapeutic approaches for radioiodine refractory thyroid cancers.

Abstract
PURPOSE The impact of sperm DNA damage on intracytoplasmic sperm injection (ICSI) outcomes remains controversial. The purpose of the study was to evaluate the prognostic value of several types of sperm nuclear damage on ICSI clinical pregnancy. METHODS Our retrospective study included a total of 132 couples who consulted for male or mixed-factor infertility that benefited from ICSI cycles from January 2006 to December 2015. All infertile males presented at least one conventional semen parameter alteration. Sperm nuclear damage was assessed using the Motile Sperm Organelle Morphological Examination for sperm head relative vacuolar area (RVA), aniline blue staining for chromatin condensation, terminal deoxynucleotidyl transferase dUTP nick-end labeling for DNA fragmentation, and fluorescence in situ hybridization for aneuploidy. RESULTS Infertile males who achieved pregnancy after ICSI had fewer chromatin condensation defects than did males who did not achieve any pregnancy (15.8 ± 12.0% vs. 11.4 ± 7.9%, respectively, P = 0.0242), which remained significant in multivariate regression analysis (RR = 0.40 [0.18 to 0.86], P = 0.02). RVA, DNA fragmentation, and aneuploidy were not predictive factors of ICSI outcomes. The pregnancy rate was significantly decreased by number of progressive motile spermatozoa with normal morphology after migration (P = 0.04). In female partners, 17β estradiol of less than 2000 pg/mL on the day of ovulation induction significantly reduced the occurrence of clinical pregnancy (P = 0.04). CONCLUSION Sperm chromatin condensation defects were more frequently observed in couples with ICSI failure and should be considered a negative predictive factor for the occurrence of clinical pregnancy.

Abstract
Umbelliprenin has recently been shown to have great potential as a skin whitening agent. Wishing to investigate the same effect in plant species known to biosynthesize this coumarin, three plants belonging to the Apiaceae family, namely Anethum graveolens L. (dill), Pimpinella anisum L. (anise), and Ferulago campestris (Besser) Grecescu (field ferula) were screened by HPLC analysis for their respective content of umbelliprenin in extracts obtained with different solvent mixtures and by maceration and ultrasound-assisted processes. EtOH was shown to be the best solvent, providing umbelliprenin yields ranging from 1.7% to 14.4% (with respect to the total amount of extract obtained). Extracts with the highest content of this farnesyloxycoumarin were then assayed as modulators of melanogenesis in cultured murine Melan A cells employing the same umbelliprenin obtained by chemical synthesis as the reference. A parallelism between the content of the coumarin and the recorded depigmenting effect (60% for the EtOH extract of F. campestris as the best value) was revealed for all plants extracts when applied at a dose of 100 μg/mL. Our results demonstrate that the same potential of umbelliprenin can be ascribed also to umbelliprenin-enriched plant extracts which reinforces enforce the widespread use of phyto-preparations for cosmetic purposes (e.g., A. graveolens).

Abstract
Beyond demonstration of conceptual relevance and synthetic feasibility of aryl/alkyl-substituted representatives, carbo-benzene molecules started to gain prospects of broader impact through the emergence of alkynyl derivatives. This is first illustrated by examples of di- and hexaalkynyl-carbo-benzenes, a carbo-naphthalene, a carbo-biphenyl, and two carbo-terphenyls. A focus is then given to dialkynyl derivatives by reference to the peripherally C2-extruded parents. In the centrosymmetric quadrupolar series, the C2 expansion or ethynylogation effect is more particularly considered for 9H-fluoren-2-yl, tris(O-n-alkyl)pyrogallyl, indol-3-yl, 4-anilinyl, and tetraphenyl-carbo-phenyl substituents on the following respective properties: two-photon absorption, chemical stability, columnar mesogenicity, on-surface photoinduced charge separation vs single-molecule conductance, and reduction potential. Topical results and prospects of application are discussed on the basis of crystallographic, spectroscopic, and electrochemical analyses vs DFT-calculated nuclear and electronic structures. For the sake of the discussion consistency, complementary experimental and computational results are disclosed in the dianilinyl series. Overall, it is shown that combined advances in strategy, protocols, and substrate scope of acetylenic synthesis remain crucial for the development of yet poorly explored but promising types of molecular materials.1 Introduction2 Hexaalkynyl-carbo-benzene3 ortho-Dialkynyl-carbo-benzene4 para-Dialkynyl-carbo-benzenes4.1 Bistrimethylsilylethynyl-carbo-benzene4.2 Bisfluorenylethynyl-carbo-benzene4.3 Bistrialkoxyarylethynyl-carbo-benzenes4.4 Bisindolylethynyl-carbo-benzene4.5 Bisanilinylethynyl-carbo-benzene5 Carbo-oligo(phenyleneethynylene)s6 Conclusions

Abstract
Abstract
Dendrogenin A (DDA) is a tumor suppressor metabolite identified in human tissues that arises from the conjugation of 5,6α-epoxycholesterol (5,6α-EC) with histamine (HA) by a yet unidentified enzyme. DDA is present in the normal breast but its levels were found drastically decreased in breast tumors, showing that a deregulation of DDA metabolism occurred during breast carcinogenesis. It was shown that DDA displayed chemopreventive and anticancer properties (de Medina et al, Nat Commun, 2013; Voisin et al, PNAS, 2017; Segala et al, Nat Commun, in press). In addition, DDA blocks the biosynthesis of a newly identified cholesterol tumor promoter named 6-oxo-cholestan-3β,5α-diol (OCDO) (Voisin et al, PNAS, 2017). DDA and OCDO arise from 5,6-EC. We showed the existence of a metabolic balance between these two 5,6-EC derivatives in normal breast and BC that controls or stimulates BC progression (Silvente-Poirot & Poirot, Science, 2014, Voisin et al, PNAS, 2017). We addressed here the question of the identification and characterization of the DDA synthase (DDAS) and we determined whether its expression could reflect DDA levels in patient breast tumor and normal tissue. We report that the recombinant human glutathione transferase A1-1 (GST A1-1) produced DDA from 5,6α-EC and histamine (HA). The chemical characterization of the DDA product was performed by chromatography and mass spectrometry fragmentation. DDAS activity was found to be a new and important activity of GST A1-1 in addition to known glutathione transferase and steroid isomerase activities. The measured Michaelis constants of GST A1-1 for its new substrates were: Km5,6α-EC=0.27±0.05 µM and KmHA=0.35±0.3 µM, and the maximum velocity for the transformation of each substrates Vm5,6α-EC=0.81±0.2 µmol.min-1.mg and VmHA=0.66±0.2 µmol.min-1.mg. Interestingly, we showed that OCDO and other ring-B oxysterols, as well as several natural substrates and product of the GST A1-1, were potent inhibitors of DDAS activity while xenobiotics substrates of GST, and side chain oxysterols were not. Patient BC samples (n=50) showed significant decreased DDA levels and lower GST A1-1 protein expression compared to normal matched tissues, indicating that the decreased production of DDA in tumors is due to decreased expression of its enzyme. The analyses of two human BC mRNA databases from the Barts Cancer Institute (London, UK) and the Curie Institute (Paris, France) showed that the expression of GST A1-1 was lost in ER(+) BC tumors compared to normal breast tissue. Interestingly, DDAS was selectively expressed in the cytoplasm of epithelial cells from lactating ducts and lobular terminal units. Since these cells are the origin of most BC, the loss of DDAS expression and DDA biosynthesis combine to OCDO production, which controls DDAS activity, may constitute a major oncogenic process leading to BC development in human.

Abstract
Umbelliprenin is a secondary plant metabolite that displays promising chemopreventive, anti-inflammatory, and antigenotoxic properties. It possesses potential for applications to human welfare notably to prevent the emergence of cancer. For this purpose, stability studies are needed to define proper storage conditions and adapted formulations for this drug candidate. The identification of degradative products is a major concern for the preclinical development of umbelliprenin, providing also interesting information related to potential original phytochemicals formed in plants exposed to stressors. The stability profile of umbelliprenin under various stress conditions including exposure to heat, light, oxidation, and hydrolytic medium was assessed via HPLC/UV data. The data support that umbelliprenin undergoes inter- and intramolecular [2+2] cycloaddition under light exposure, leading respectively to a cyclobutane-umbelliprenin dimer and a 16-membered macrocycle. Their structures were characterized via MS and NMR data. It was shown that UV-A filters prevent this process, whereas UV-B filters and antioxidants are not or weakly effective. The study provides useful information for the preclinical development of umbelliprenin as an original chemopreventive agent.

Solubilization of the C18 fundamental circuit of α-graphyne has been envisaged by decoration with aliphatic chains R = n-CnH2n+1. The synthesis and characterization of p-dialkyl-tetraphenyl-carbo-benzenes (n = 2, 8, 14, 20) are thus presented and compared to the monoalkyl series produced concomitantly. In both series, a dramatic enhancement of solubility in organic solvents (CH2Cl2, CHCl3) is observed for n ≥ 8, and in the dialkyl series, the melting-decomposition temperature of the solid products is shown to decrease linearly from 208 °C for n = 2 to 149 °C for n = 20. Fluoroalkyl analogues with R = n-C8H4F13 are also described. The products display classical UV-vis electronic spectra of carbo-benzenes in solution (λmax = 445.5 ± 1 nm, ε ≈ 200 000 L·mol-1·cm-1). They are also characterized by UV-vis absorption in the solid state, which is found to be correlated with the color and crystal packing. The methylene groups of R provide an experimental probe of the magnetic anisotropy and aromaticity of the C18 ring through the progressive NMR shielding of the 1H nuclei from ca. 4.70 to 1.25 ppm going away from the border of the ring (as far as 8 Å away). All alkyl-carbo-benzenes were also found to be highly crystalline. Seven of them have been characterized by X-ray diffraction analysis and the C18 columnar packing compared in a systematic manner. Crystals of the diethyl and bistetradecyl derivatives, containing no solvent molecule, provided the first examples of direct π-stacking of carbo-benzene rings, with inter-ring distances very close to calculated interlayer distances in AB and ABC α-graphityne (3.255 and 3.206 Å vs 3.266 and 3.201 Å, respectively).

Abstract
Ideally Cs-/C2v-symmetric chromophores, constituted by two electro-active groups conjugated through the carbo-mer of the cyclohexa-1,3-diene core, are selectively prepared by the SnCl2-mediated reduction of tailored hexaoxy-[6]pericyclynes: in the latter substrates, one of the 1,4-dioxybut-2-yne edges is "chemically locked" by two CF3 substituents preventing complete reduction to the corresponding aromatic carbo-benzenic core, which is expected to be more "π-insulating" between the electro-active ends. The bis-trifluoromethylated carbo-cyclohexadiene products are also shown to be significantly stabilized with respect to their bis-phenylated analogues. Their structural (crystal X-ray diffraction analyses), spectroscopical (NMR and UV-vis spectra), physio-optical (dichromism in solution) and electrochemical (cyclic voltammograms) properties are compared on the basis of the electron-donating/electron-withdrawing nature of the substituents. These properties are also compared with those of their aromatic carbo-benzene and flexible carbo-n-butadiene counterparts.

Abstract
While a series of carbo-mers of 1,3-cyclohexadienes was reported through the use of a specifically developed synthetic strategy, no example of their 1,4-regioisomers was known. Inspired by the methodology elaborated for the preparation of the 1,3-isomers, the synthesis of the first example of carbo-mer of 1,4-cyclohexadiene is presented. Comparison of physico-chemical properties of this first representative with those of the recently described 1,4-regioisomer, especially UV-vis absorption properties, is also addressed.

Abstract
The macro-aromatic carbo-benzene core para-disubstituted by 4-anilinyl groups is known to be an efficient single-molecule conductor, exhibiting a conductance of 106 nS measured by the scanning tunneling microscopy-break junction technique. The linear carbo-butadiene analogue bearing the same anilinyl substituents was found to be less efficient, with a conductance of 2.7 nS. The reason of this difference could be elucidated through the study of the charge transport properties of a cyclically locked carbo-butadiene core in a carbo-cyclohexadiene derivative. In this paper, advances in the synthesis of this challenging dianilinyl-substituted carbo-cyclohexadiene are presented.

Abstract
A straightforward access to pyrrolidine-based analogues of jaspine B was developed. Five stereoisomers were prepared including the all-cis derivatives presenting the configuration of the natural anhydrophytosphingosine. The synthesis of the latter relied on an original Staudinger-type cyclization process. The compounds were evaluated regarding their ability to alter tumor cells' viability and to interfere with the metabolism of sphingolipids.

Abstract
Three groups of Sprague-Dawley CD rats (males and females) were initially administered p.o. with ebrotidine, a novel H2-receptor antagonist, mixed with the diet, at 50, 200, and 500 mg/kg/d, respectively. Two concurrent control groups of animals were used. After 13 months, initial 200 mg/kg was lowered to 150 mg/kg, and a new group was administered with 300 mg/kg, due to the body weight reduction observed in the top dose group. After 24 months, survivors were killed and necropsied, and a histopathological study was performed. The frequencies of the different tumour types that were found were not raised due to the treatment. Lower frequencies of some types of pituitary and mammary gland tumours, in the groups treated with the higher doses, were the only statistically significant changes. Among the non-neoplastic effects, a lower body weight increment and food consumption (500 and 300 mg/kg, both sexes), lower survival (500 mg/kg, males), presence of lipoid pneumonia (500 mg/kg, only in males, and 300 mg/kg, both sexes), and lithiasis in urinary system (500 mg/kg) were observed. No changes in gastric mucosa (the main target organ) were attributable to ebrotidine. Regarding the non-neoplastic effects, 150 mg/kg was the no observed adverse effect level. According to the previous results of the carcinogenicity study in mice, conjointly with those of the study in rats reported here, there is no evidence of carcinogenic risk either in males or in females in these species.

Abstract
The results from two carcinogenicity studies on ebrotidine (N-[2-(E)-[[2-[[[2-[(diaminomethylene)amino]-4-thiazolyl] methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfonamide, CAS 100981-43-9, FI-3542) conducted in mice and rats are reported. Oral doses of 50, 200 and 500 mg/kg were administered to mice for 18 months and 50, 200 (150), 300 and 500 mg/kg were administered to rats for 24 months. The study design was prepared according to EEC guidelines, and the recommendations by the International Agency for Research on Cancer were used for the statistical analysis of data. Weekly palpations were made along the course of studies and general parameters were monitored. The only effects attributed to ebrotidine administration were a slight decrease in the survival rate of female mice given the 500 mg/kg dose and a lower weight gain in rats of both sexes. The histopathological data revealed that lipoid pneumonia and kidney calculi are more frequent in rats treated with doses of 500 and 300 mg/kg. No increment in the spontaneous occurrence of tumours or significant presence of tumours in treated animals differing from that in control animals was observed, and a decrease in the time required for their onset that could be related to ebrotidine was not observed either. There were no differences in hyperplastic and/or dysplastic changes between treated and control animals. Therefore, it is deduced that ebrotidine does not induce neoplastic or preneoplastic effects in rats or mice even at doses of 500 mg/kg, at which some general toxicity effects are seen.

Abstract
The spread of Vesical Neoplasia occurs frequently through local or regional extension. Its systemic dissemination happens frequently in advanced phases but it is exceptional as initial manifestation. The case of an undifferentiated vesical carcinoma is described, its presentation was as a big size osteolytic lesion on the sacrum. Local manifestations of the tumor appeared later. The study performed both in bones as well as in the vesical mucosa showed an undifferentiated adenocarcinoma. The great resemblance and histological and immunohistochemical concordances of both biopsies confirmed that it was a primary vesical neoplasia with a metastasis in sacrum. The specific clinical evolution of this tumor is discussed which is probably related with the fact that it is an undifferentiated carcinoma.

Abstract
A 24-year-old man developed progressive dementia in seven years. The patient suffered a severe bronchopneumonia and eventually died few days later. Brain coronal sections showed a soft gray-brownish discoloration of white matter of centrum ovale but the subcortical arcuate fibers and the interne capsule were preserved. Microscopically, the white matter showed marked loss of myelin and oligodendrocytes, abundant hypertrophic astrocytes and numerous "globoid cells". The latter showed strong positivity in immunostains for a mouse monoclonal antigalactocerebroside antibody. The presence of these cells in the brain white matter might be the morphological basis to classify the present case as one of Krabbe's Leukodystrophy.

Abstract
Several authors have suggested that the risk of developing aminoglycoside nephrotoxicity is greater in cirrhotic patients than in the noncirrhotic population. However, this has not been confirmed by other investigators. To compare the intensity and characteristics of aminoglycoside nephrotoxicity in cirrhotic and normal rats, 31 rats with carbon tetrachloride-induced cirrhosis with ascites and 35 control rats were treated with gentamicin. Each group of rats was divided into two subgroups in order to receive 10 or 40 mg per kg per day of gentamicin, and different subsets of animals were killed on Days 4, 8 and 12 of treatment for renal histological examination and determination of renal tissue gentamicin concentration. Urine volume, osmolality, sodium excretion and N-acetyl-beta-D-glucosaminidase activity were measured daily throughout the study. Creatinine clearance and trough plasma concentration of gentamicin were determined in each animal immediately before killing. There were no significant differences between cirrhotic and control rats in relation to the magnitude of changes in urine volume, osmolality, sodium excretion and N-acetyl-beta-D-glucosaminidase activity and creatinine clearance during gentamicin administration. The values of a histopathological score semiquantitatively assessing the renal morphological changes observed by light microscopy were not significantly different in cirrhotic and control rats. In addition, similar trough plasma and renal cortical tissue concentrations of gentamicin were observed in both groups of animals. These results suggest that, in this experimental model, cirrhosis does not increase the risk for aminoglycoside nephrotoxicity.

Abstract
A two-generation reproduction-fertility study of cyanamide in the rat has been carried out. After oral administration of 2, 7 and 25 mg/kg/day of the drug, relevant changes have been noted at the highest dose level. Decrease in dam weight gain, in number of corpora lutea, in number of implantations and in number of neonates have been observed in rats of the Fo generation after treatment with 25 mg/kg/day. This group showed a reduced fertility rate and decreases in the weight of several reproductive organs male rats. In contrast to the findings noted in the Fo generation, changes related to cyanamide treatment have not been observed in the F1 generation. Histopathology of these organs has disclosed a low incidence of bilateral testicular atrophy. Decreased fertility rate due to non-specific toxicity associated with a diminished food intake cannot be discarded.

Abstract
Investigations were carried out in 122 patients in order to identify features of Sjögren's syndrome (keratoconjunctivitis sicca and xerostomia). There were 78 patients with autoimmune diseases (rheumatoid arthritis 21, scleroderma 16, sicca syndrome 16, primary biliary cirrhosis 14, and other autoimmune disorders 11), 11 patients with chronic liver disease other than primary biliary cirrhosis, and 33 patients with a variety of non-autoimmune conditions or no obvious disease. Keratoconjunctivitis sicca was diagnosed by Schirmer's test and rose bengal staining. The oral component was diagnosed by labial biopsy and salivary scintigraphy. Forty nine patients had a definite Sjögren's syndrome, and 77 patients had the syndrome definitely or probably. Definite Sjögren's syndrome occurred in 62% of patients with rheumatoid arthritis, in 69% of patients with scleroderma, and in 71% of patients with primary biliary cirrhosis. Sjögren's syndrome was not present in any of the patients with non-autoimmune conditions. These results show that in an unselected group of patients with Sjögren's syndrome the prevalence of rheumatoid arthritis (26%), scleroderma (22%), sicca syndrome (22%), and primary biliary cirrhosis (20%) is similar. Also the occurrence of Sjögren's syndrome in primary biliary cirrhosis is even higher than that in rheumatoid arthritis.
