CONTEXT Increased Anti-Mullerian Hormone in polycystic ovary syndrome, may be due to overactive follicles rather than reflect antral follicle count. OBJECTIVE Does Anti-Mullerian Hormone reflect antral follicle count similarly in women with or without polycystic ovary syndrome or polycystic ovarian morphology? DESIGN Cross-sectional, case-control. SETTING Women who delivered preterm in 19...
BACKGROUND Hypothesizing that redundant functional ovarian reserve (FOR) at young ages may clinically obfuscate prematurely diminished FOR (PDFOR), we investigated in young oocyte donors genotypes and sub-genotypes of the FMR1 gene, in prior studies associated with specific ovarian aging patterns, and determined whether they already at such young age were associated with variations in ovarian r...
A system of 16 non-linear, delay differential equations with 66 parameters is developed to model hormonal regulation of the menstrual cycle of a woman from age 20 to 51. This mechanistic model predicts changes in follicle numbers and reproductive hormones that naturally occur over that time span. In particular, the model illustrates the decline in the pool of primordial follicles from age 20 to...
Agents' behaviour is not only dictated by utility calculus, as has frequently been proposed. Even if we adopt a welfarist design, interests and not utilities seem to guide a very important part of agents' behaviour in Multi-Agent Systems (MAS). Agents have rights that protect their interests against additive utilities: Rights allow them enough freedom, but at the same time constrain them (prohi...
The aim of this paper is to provide non-specialist readers with an introduction to some current controversies surrounding the application of evolutionary theory to human behaviour at the intersection of biology, psychology and anthropology. We review the three major contemporary sub-fields; namely Human Behavioural Ecology, Evolutionary Psychology and Cultural Evolution, and we compare their vi...
In this report, which continues the work by the same authors presented in Report 94.1 of the School of Computer Studies, we explore the effectiveness of three new variants on the method of Parallel Multi-Dimensional Search (PMDS) due to Torczon (1989). Since PMDS is acknowledged to be very slow at low dimensions we propose geometrically based variants which prove to be very effective over a ran...
Chinese tongue sole is a marine fish with ZW sex determination. Genome sequencing suggested that the Z-linked dmrt1 is a putative male determination gene, but direct genetic evidence is still lacking. Here we show that TALEN of dmrt1 efficiently induced mutations of this gene. The ZZ dmrt1 mutant fish developed ovary-like testis, and the spermatogenesis was disrupted. The female-related genes f...
The concentration of circulating anti-Müllerian hormone (AMH) in cattle is a useful endocrine marker for ovarian response to superovulation. Although the AMH concentration undergoes little variation throughout the estrous cycle, its long-term changes remain incompletely understood. Here, we investigated the relationship between superovulation response and plasma AMH concentration in Japanese Bl...
BACKGROUND The implementation of the Performance Management and Development System (PMDS) is seen as being vital to the quality of care, resource management and inter-professional work. However, there is evidence that, at present, professional nurses lack the knowledge to implement such a system. OBJECTIVES The aim of this study was to explore and describe professional nurses' knowledge regar...
Anti-Müllerian hormone (AMH) is now accepted as an important clinical marker of ovarian reserve and is increasingly measured as an initial evaluation at infertility clinics. The aim of this study was to establish reference values for the revised second generation (Gen II) assay using population-based data. In this population-based cohort study, AMH data from unselected infertile women aged 25-4...
