Abstract
Following adoption of moderately hypofractionated radiotherapy as a standard for localised prostate cancer, ultrahypofractioned radiotherapy delivered in five to seven fractions is rapidly being embraced by clinical practice and international guidelines. However, the question remains: how low can we go? Can radiotherapy for prostate cancer be delivered in fewer than five fractions? The current review summarises the evidence that radiotherapy for localised prostate cancer can be safely and effectively delivered in fewer than five fractions using high dose rate brachytherapy or stereotactic body radiotherapy. We also discuss important lessons learned from the single-fraction high dose rate brachytherapy experience.

Abstract
Alteration of sperm parameters related to occupational exposures is the subject of several studies, often on a case-control approach. The study populations usually comprise men consulting in infertility clinics for couple infertility. The objective of this review is to identify, from these case-control studies, the main occupational factors that may be associated with altered sperm parameters. We selected 13 articles in the PubMed database. Participation in these studies varied from 61 to 2619 subjects, with great methodological heterogeneity, particularly in the characterization of exposure. The main occupations that appear significantly associated with a risk of altered sperm parameters are workmen, painters, farmers, welders, plumbers and technicians. When analysis focuses on occupational exposures, a significant result is reported for solvents, heavy metals, heat, vibrations and non-ionizing radiation. None of the selected studies has found a link with exposure to pesticides.

Abstract
BACKGROUND Epicardial adipose tissue (EAT) is in close contact with coronary vessels and therefore could alter coronary homeostasis. Glucocorticoids are pathophysiological mediators of visceral fat deposition and its associated atherogenic complications. AIM We investigated in EAT the expression of the glucocorticoid receptor (GR) and its various (A, B, C) promoters. MATERIALS AND METHODS Paired subcutaneous adipose tissue (SAT) and EAT biopsies were obtained from 15 patients with coronary artery disease (CAD) and 12 patients without CAD (NCAD). GR and 11β-hydroxysteroid dehydrogenase type 1 protein (11β-HSD-1, the enzyme which converts inactive cortisone into active cortisol) were studied by immunohistochemistry and GR and its various promoters were studied by mRNA quantitative RT-PCR. RESULTS GR and 11β-HSD-1 protein were expressed in adipocytes, stromal areas, isolated stromal cells close to adipocytes, and blood vessels. Total GR mRNA levels did not differ in SAT obtained from NCAD or CAD patients and were decreased in EAT, irrespectively of the coronary status, with parallel changes in promoter B- and C-, but not promoter A-associated transcripts. Total GR mRNA and adipocyte surface in EAT obtained from CAD patients were correlated negatively (p<0.035, r=0.39). CONCLUSIONS Our findings demonstrate that in EAT, GR gene promoters could play a role in tissue- specific GR expression levels. EAT may be less sensitive to glucocorticoids than SAT, preventing the EAT mass development in CAD patients and suggesting a protective role on coronary homeostasis.

Abstract
BACKGROUND Early life nutritional environment plays an important role in the development of visceral adipose tissue and interacts with nutritional regulations in adulthood, leading to metabolic dysregulations. AIM We hypothesized that the renin-angiotensin system may play a role in the programming-induced development of visceral adipose tissue. MATERIAL AND METHODS We studied, using a model of programming of overweight and glucose intolerance, obtained by post-natal overfeeding with consecutive highfat diet, the status of plasma renin activity and mesenteric adipose renin-angiotensin system, including the recently identified (pro)renin receptor, in adult rats. RESULTS Post-natal overfeeding or high-fat feeding lead to overweight with increased visceral fat mass and adipocytes surface. When both paradigms were associated, adipocytes surface showed a disproportionate increase. A strong immunoreactivity for (pro)renin receptor was found in stromal cells. Plasma renin activity increased in programmed animals whereas (pro)renin receptor expressing cells density was stimulated by high-fat diet. There was a positive, linear relationship between plasma renin activity and (pro)renin receptor expressing cells density and adipocytes surface. CONCLUSIONS Our experiments demonstrate that association of post-natal overfeeding and high-fat diet increased plasma renin activity and adipose (pro)renin receptor expression. Such phenomenon could explain, at least in part, the associated disproportionate adipocyte hypertrophy and its accompanying increased glucose intolerance.

Abstract
It has been hypothesized that sleep apnea syndrome (SAS) increases hypothalamic-pituitary-adrenal axis activity and, through increased cortisol levels, participates in the pathophysiology of metabolic and cardiovascular complications. We compared the circadian profiles of cortisol in obese men with [obSAS+; apnea-hypopnea index (AHI) >or= 20/h] and without SAS (obSAS-; AHI <or= 5/h). 1) Salivary cortisol (5 samples: before/30 min after dinner, 2100, upon/30 min after awakening) was measured in 15 obSAS+, 19 obSAS-, and 19 normal-weight controls (NWC). 2) Plasma cortisol (every 30 min for 24 h under highly controlled conditions and portable EEG device) was measured in 9 obSAS+, 8 obSAS-, and 10 NWC men. Visceral adipose tissue surface was measured by CT scan. In both studies, obSAS+ and obSAS- men were comparable for age, BMI, waist circumference, and waist-to-hip ratio. First, no difference was found, using ANOVA for repeated measures, between obSAS+ and obSAS- subjects for any salivary cortisol measurement. No correlation was found between salivary cortisol and AHI or nocturnal SaO(2). Similarly, obSAS+ and obSAS- men showed no difference in plasma cortisol rhythmicity: 24-h minimum, maximum, and mean, ANOVA for repeated measures, mathematical modeling of cortisol rhythm (COSINOR), and morning secretory peak. Conversely, ANOVA for repeated measures showed decreased cortisol levels in obese vs. NWC men during both the trough (2200-0130) and the peak (0600-0900) independently of SAS status. We show that SAS per se is not associated with any change of the level or of the features of salivary and plasma cortisol rhythmicity and confirm that men with visceral obesity display lower plasma cortisol levels than NWC men.

Abstract
OBJECTIVE Adrenomedullin (AM), a potent vasodilatator and antioxidative peptide, was shown recently to be expressed by adipose tissue. The aim of our study was to investigate the precise localization of AM within human adipose tissue, and to examine AM regulation in obesity. DESIGN Subcutaneous (SC) and omental (OM) adipose tissues from 9 lean and 13 obese women were profiled for AM expression changes. Preadipocytes from human adipose tissue were isolated and differentiated under defined adipogenic conditions. METHODS AM expression was analyzed by immunohistochemistry, in situ hybridization and quantitative RT-PCR. RESULTS A strong AM expression was observed in vessel walls, stromal cell clusters and isolated stromal cells, some of them being CD 68 positive, whereas mature adipocytes were not labeled. Calcitonin receptor-like receptor and receptor activity-modifying proteins (RAMP) 2 and RAMP 3 were expressed in vessel walls. In vitro, preadipocytes of early differentiation stages spontaneously secreted AM. No difference in AM localization was found between SC and OM adipose tissue. AM levels in SC tissue did not differ between lean and obese subjects. By contrast, AM levels in OM tissue were significantly higher in obese as compared with lean women. Moreover, we found a positive relationship between OM AM and tumor necrosis factor alpha mRNA levels and AM-immunoreactive area in OM tissue followed the features of the metabolic syndrome. CONCLUSION Stromal cells from human adipose tissue, including macrophages, produce AM. Its synthesis increased in the OM territory during obesity and paralleled the features of the metabolic syndrome. Therefore, AM should be considered as a new member of the adipokine family.

Abstract
OBJECTIVE Our aim was to analyse the results of a donor insemination program using ovarian stimulation, swim-up sperm preparation and intrauterine insemination proposed to women with a maximum age of 39. Incidence of several clinical and biological parameters on success rates was investigated. PATIENTS AND METHODS Retrospective analysis of the results of 249 cycles performed in 106 couples during a four-year period is reported. RESULTS Overall pregnancy rate of 28.1% and delivery rate of 22% per cycle were achieved, with a multiple pregnancy rate of 11.4%. Most of the pregnancies (84%) were obtained before the fourth insemination. Among the different parameters studied the total number of motile sperm inseminated was found to be the most important factor for success rate: pregnancy rate per cycle reached 40.4% if more than 1.5 million progressive sperm were inseminated vs. 24.7% if they were less than 1.5 million (P<0.05). DISCUSSION AND CONCLUSION In precise conditions, outcome of inseminations with donor semen can reach satisfying pregnancy rates, being a valuable help for couples suffering of long-time infertility.

Abstract
We report ICSI pregnancies in two couples with a history of long standing primary infertility in which the sperm of the male partner were either acephalic or had abnormal head-midpiece attachments. The two couples, in which the men are brothers, underwent ICSI. Sperm were analysed by transmission electron microscopy and immunocytochemistry with an anti-MPM2 monoclonal antibody. The first couple underwent two ICSI cycles, each consisting of the injection of two mature oocytes and the transfer of two embryos. A successful pregnancy occurred after the second transfer and led to the birth to a healthy girl. The second couple underwent three ICSI cycles, each consisting of the injection of 18 oocytes and the transfer of two embryos; the last of these led to a triple ongoing pregnancy which included two identical twins. Caesarean section led to the birth of three fetal-growth restricted children. This case report demonstrates that ongoing pregnancies can be achieved in cases of abnormal development of the head-neck attachment. The genetic origin of this syndrome is generally accepted, but the phenotypic heterogeneity observed by light and electron microscopy among published cases suggests that there are a variety of genetic causes of this syndrome.
