Oxidative stress (OS) may affect natural fertility and the results of assisted reproduction techniques (ARTs). Subfertility associated with polycystic ovary syndrome (PCOS) may be related to OS. This process may intensify during controlled ovarian stimulation (COS) for ARTs because of increased ovarian metabolic activity and hypoestrogenism with the use of gonadotropin-releasing hormone agonists (GnRHas). The objective of this study was to investigate the presence of systemic OS in non-stimulated cycles ...

Excavation counts (absolute density), burrow counts and surface active individuals visual counts in a Uca tangeri population were compared. Population density estimated from burrow counts was not significantly different from population density estimated by excavation, but the population density estimated with visual counts was significantly lower than the absolute density. Ovigerous females should be the main cause of these differences because they frequently remain underground, but other groups ...

Early endometriosis is associated with infertility, and oxidative stress may play a role in the pathogenesis of disease‐related infertility. This prospective case‐control study aimed to compare the presence of oxidative stress markers in the follicular microenvironment and systemic circulation of infertile women with minimal/mild endometriosis (EI/II) versus individuals undergoing controlled ovarian stimulation for intracytoplasmic sperm injection (ICSI). Seventy‐one blood samples (27 from infertile ...

The major claw of male fiddler crabs, reaching up to 40% of the individual's total body weight, may impose a cost on males when escaping from predators. To test this hypothesis, 38 males (18 without the major claw) and 19 females were randomly captured and placed, individually, in a straight track. After a five-minute adaptation period, an observer walked toward the crab and triggered its escape reaction. Each crab was subjected to 10 trials with 5-minute intervals between them. The central area ...

Abstract In many practical situations, internal nodes connect beams with unequal depth whenever the span lengths are not uniform. Following the methodology defined in EC 3‐1‐8, this paper presents a component model that is able to reproduce accurately the complex behavior of welded beam‐to‐column joints with beams of unequal height, which corresponds to a node configuration that is not yet covered in the EC 3 design rules. Based on an experimental program carried out at the University of Coimbra, ...

We investigated the visual ecology of the coloration of the eastern Atlantic fiddler crab, Uca tangeri, with particular attention to predator (e.g. avian) and conspecific vision. Spectral reflectance measurements were made on different body parts used in possible intraspecific communication as well as background habitats including crab-made materials (e.g. mudballs). Avian-based and crab-based visual models were used to obtain different estimates of crab conspicuousness to potential predators and ...

Fiddler crabs have compound eyes that are structurally fairly well understood. However, there has been much debate regarding their spectral sensitivity and capacity to enable colour discrimination. We examined the visual pigments of two North-American species (Uca pugnax and U. pugilator), one species from the Indo-West Pacific (U. vomeris) and the only Eastern-Atlantic species (U. tangeri) of fiddler crabs using in situ microspectrophotometry of frozen sections of dark-adapted eyes. Only one spectral ...

A 78-year-old woman was admitted to our hospital with a pancreatic tumor, incidentally discovered in an abdominal ultrasound exam. She was asymptomatic and without any previous personal pathological condition. The computed tomography (CT) and the magnetic resonance imaging (MRI) scan showed a mass lesion of 4 cm in diameter, located in the pancreatic body, conditioning the invasion of the splenic vein. The patient was admitted to surgery. During the laparotomy, we found a tumoral lesion highly suspicious ...

The objective of the current paper is to characterise the behaviour of internal asymmetric joints, which corresponds to a node configuration that is not yet covered in the EN 1993-1-8 design rules. For this purpose, a research programme was established that encompasses five different types of joints. Numerical models were prepared and calibrated with results from experimental tests on full scale models of the joints. The analyses of the results allowed the identification of the main features that ...

The last generation of high performance steels encompasses significant advantages in terms of economy, architectural possibilities and environmental sustainability, featuring remarkable technological items. In spite of that, the market share it holds does not yet reflect its competitiveness. One of the most important reasons for that has to do with the due update of regulation codes. In Europe, not long ago EC3 would still limit its scope to S460. EC3 Part 1-12 bridges that gap, extending its scope ...

We measured temporal and spatial components of the waving display in a Uca tangeri population to look for inter-individual differences in male waving structure that may convey information about individual identity. We found evidence that the spatial components of wave structure, especially “Maximum amplitude” are responsible for most of the between-male variation of the display. This variation could reflect differences in individuals’ condition and/or could be used by conspecifics to discriminate ...

Abstract The 'aggressive wandering' behaviour of male fiddler crabs is well documented in several species and is usually described as an apparently random movement through a population, punctuated by threats and combat directed at displaying males, and superficial burrow explorations. It has been suggested that wandering males are mainly low condition individuals with a regenerating major claw, unsuccessful at attracting mates, wandering through the population seeking surface copulations as an alternative ...

Rice irrigation by continuous flooding is highly water demanding in comparison with most methods applied in the irrigation of other crops, due to a significant deep percolation and surface drainage of paddies. The pollution of water resources and methane emissions are other environmental problems of rice agroecosystems, which require effective agronomic changes to safeguard its sustainable production. To contribute to this solution, an experimental study of alternate wetting and drying flooding ( ...

Abstract Male fiddler crabs have one of their feeding claws greatly enlarged, which may comprise up to 40% of their weight. In southern Portugal (Ria Formosa) the major claw of the fiddler crab Uca tangeri is a local delicacy. Fishermen break off the male major claw and throw the crab back into the mudflat to regenerate a new one. Approximately 38 % of the males sampled had a missing or a regenerating claw. Although individuals are not removed from the population the operational sex ratio is biased ...

Abstract In Europe, the mean incidence of urinary tract infections in intensive care units is 1.1 per 1000 patient‐days. Of these cases, catheter‐associated urinary tract infections (CAUTI) account for 98%. In total, CAUTI in hospitals is estimated to give additional health‐care costs of £1–2.5 billion in the United Kingdom alone. This is in sharp contrast to the low cost of urinary catheters and emphasizes the need for innovative products that reduce the incidence rate of CAUTI. Ureteral stents and ...

Dehydroepiandrosterone (DHEA) is an adrenal steroid hormone that is a precursor of sexual hormones. It is reduced during aging and is strongly associated with insulin resistance and obesity. There is evidence for beneficial effects of this steroid, in both human and animal models, during perimenopause. However, the impact of DHEA treatment during late postmenopause on glucose metabolism is not clearly documented. We tested the hypothesis that DHEA supplementation could improve insulin sensitivity ...
