The main differences in the reproductive parameters were recorded between the beginning and the end of the reproductive season, probably because in these periods females exclusively use one of the breeding strategies. Finally, we determined that both factors, that is, female age and the periods of the short reproductive season, can modulate the reproductive performance of L. uruguayensis in temperate estuaries.AbstractFeeding larvae of echinoderms appear to differ in scope for adaptive developmental plasticity in response to food. Extension of the ciliary band on narrow arms supported by skeletal rods, as in echinoid and ophiuroid larvae, may enable a greater increase in maximum clearance rate per cell added, conferring greater advantages from developing longer ciliary bands when food is scarce. Formation of the juvenile mouth and water vascular system at a new site, as in echinoid and asteroid larvae, permits extensive growth of the juvenile rudiment during larval feeding, with advantages from earlier or more growth of the rudiment when food is abundant. In contrast, plasticity in storage of nutrients is unrelated to the form of the ciliary band or the site of formation of the juvenile's mouth. Feeding larvae (auriculariae) of holothuroids lack arms supported by skeletal rods and formation of the mouth at a new site but as a unique feature store nutrients in hyaline spheres. In this study, more food for auriculariae of Apostichopus californicus resulted in juveniles (pentactulae) with longer and wider bodies and larger hyaline spheres, but effects of food supply on the size of most body parts of auriculariae were small. Auriculariae with more food developed relatively larger stomachs and larger posterior hyaline spheres, indications of greater nutrient storage. Auriculariae with less food developed relatively wider mouths and differed in some exterior dimensions, which might enhance the capture of food. Plasticity is limited in rudiment development and perhaps in structures for feeding, but plasticity in nutrient storage can provide advantageous compromises between duration of growth as a feeding larva and the condition of juveniles formed at metamorphosis.AbstractWe tested the impact of temperature and symbiont state on calcification in corals, using the facultatively symbiotic coral Astrangia poculata as a model system. Symbiotic and aposymbiotic colonies of A. poculata were reared in 15, 20, and 27 °C conditions. We used scanning electron microscopy to quantify how these physiological and environmental conditions impact skeletal structure. Buoyant weight data over time revealed that temperature significantly affects calcification rates. Scanning electron microscopy of A. poculata skeletons showed that aposymbiotic colonies appear to have a lower density of calcium carbonate in actively growing septal spines. We describe a novel approach to analyze the roughness and texture of scanning electron microscopy images. Quantitative analysis of the roughness of septal spines revealed that aposymbiotic colonies have a rougher surface than symbiotic colonies in tropical conditions (27 °C). This trend reversed at 15 °C, a temperature at which the symbionts of A. poculata may exhibit parasitic properties. Analysis of surface texture patterns showed that temperature impacts the spatial variance of crystals on the spine surface. Few published studies have examined the skeleton of A. poculata by using scanning electron microscopy. Our approach provides a way to study detailed changes in skeletal microstructure in response to environmental parameters and can serve as a proxy for more expensive and time-consuming analyses. Utilizing a facultatively symbiotic coral that is native to both temperate and tropical regions provides new insights into the impact of both symbiosis and temperature on calcification in corals.

To analyze the visual and refractive results after secondary IOL implantation using different surgical techniques - iris-claw aphakic IOL through a corneal incision or scleral tunnel, and 3-piece IOL into the ciliary sulcus.

Retrospective study including patients that were submitted to secondary IOL implantation from January 2017 to December 2019 at the Department of Ophthalmology of Hospital de Braga, Portugal. We collected demographic data (age, surgical indication, comorbidities, surgical technique, IOL implanted, and intra and postoperative complications) and visual and refractive data [preoperative and 3-month, 6-month, and 12-month postoperative corrected-distance visual acuity (CDVA), spherical equivalent (SE), manifest cylinder, and intraocular pressure].

128 eyes from 123 patients were included. The most frequent surgical indications were IOL subluxation/luxation (62.5%) and intraoperative posterior capsular rupture (23.4%). XL092 cost CDVA improved from 1.26±0.51 to 0.47±0.49 logMar (p<.001). CDVA wasaw IOL group.Photovoice has gained acceptance as a viable visual method to engage community members as partners in research. However, as methods associated with photovoice have developed and evolved over time, concerns have also been raised with regard to how this impacts the methodological underpinnings on which photovoice rests. The aim of this article is to explore the meaning of dialogue and action as methodologically pivotal for the relevance of photovoice as community-based participatory research; further, using an empirical case and narrative theory, we attempt to contribute to an understanding of the processes that facilitate the viability and relevance of photovoice. By unpacking the contributions of dialogue and action towards a participatory methodology, in this case photovoice, the authors illustrate and argue for aspects critical in photovoice. Drawing on these aspects provides an arena for storytelling and story making, which have not previously had an explicit part in photovoice.

The availability of non-invasive means to evaluate and monitor tendon-bone healing processes

is limited. Micro Positron-Emission-Tomography (µPET) using

F-Fluoride is a minimally invasive imaging modality, with which osteoblast activity and bone turnover can be assessed. The aim of this study was to investigate the use of serial

µPET/CT scans to evaluate bone turnover along the graft-tunnel interface in a rat ACL (anterior cruciate ligament) reconstruction model.

Unilateral autograft ACL reconstruction was performed in six rats. µPET/CT-scans using

F-Fluoride were performed 7, 14, 21, and 28days postoperatively. Standard uptake values (SUV) were calculated for three tunnel regions (intraarticular aperture (IAA), mid-tunnel, and extraarticular aperture (EAA)) of the proximal tibia. Animals were sacrificed at 28 days and evaluated with µCT and histological analysis.

SUVs in both bone tunnels showed an increased

F-Fluoride uptake at 7days when compared to 14, 21, and 28days. SUVs showed a gradient on the tibial side, with most bone turnover in the IAA and least in the EAA. At 7, 14, 21, and 28days, there were significantly higher SUV values in the IAA compared to the EAA (

= .01, < .01, < .01, < .01). SUVs positively correlated with new bone volumetric density obtained with μCT (r = 0.449,

= .013). Volumetric density of newly formed bone detected on μCT correlated with osteoblast numbers observed along the tunnels in histological sections (r = 0.452,

< .016).

Serial

µPET/CT-scanning has the potential to provide insight into bone turnover and therefore osteoblastic activity during the healing process. As a result, it allows us to directly measure the effect of interventional strategies in tendon-bone healing.

We have examined the history of the development of his protocols for mapping dermatomes by analyzing his lectures and publications from 1908 to 1939, focusing on his Schorstein Memorial Lecture in 1932 and his use of the isolation (Sherrington) method, in which a single dorsal root is spared in a sequence of resections (dorsal rhizotomies). Because of the absence of medical records for Foerster's patients, we also review eyewitness accounts of his operating technique, his occasional comments on patients, and the issue of consent. There appears to be no medical justification-at that time or currently-for Foerster's use of the Sherrington method to map dermatomes L1, L5, S1, and S2, and in our view, these results were obtained unethically. Hence, clinicians and researchers who use his maps should acknowledge those whom Foerster exploited in order to produce them.This paper reviews recent contributions from a Bayesian-oriented perspective, after the ASA statement on p-values (2016). We classify proposals that (i) supplement the p-value; (ii) modify the p-value itself. In the first group, we review the Bayes factor, the False Positive risk, the rejection odds and the analysis of credibility from both Matthews' and Held's point of view. We also put forth and discuss a new index of credibility, about which we conduct a delimited simulation study. In the second group, we discuss Gannon's modification of the p-value based on the Bayes factor and the second-generation p-value. The theory is illustrated with two case studies on pharmacotherapy in infectious diseases. Contemporary authors still refer to the p-value as a statistical indicator but have abandoned the perspective of evaluating p-values with fixed thresholds. Statistical societies worldwide should target new strategies to disseminate the debate on p-values in all applied fields of knowledge, as well as they may promote the use of different statistical procedures to supplement p-values.Anatomical and physiological specializations for plant adaptation to harsh climates result from molecular mechanisms that can be encoded in the nucleus or organelle. In this study, the complete plastomes of an arctic species, Oxytropis arctobia Bunge (Fabaceae), and a closely related temperate species, O. splendens Douglas ex Hook., were assembled, annotated, and analyzed to identify differences that might help explain their adaptation to different environments. This is consistent with the previously sequenced O. bicolor DC. and O. glabra plastomes, O. arctobia and O. splendens plastomes both have the common features of the inverted repeat-lacking clade (IRLC), as well as atpF intron loss, which is unique to the genus. However, significant differences were observed between the plastomes of O. arctobia and O. splendens and other closely related species (Oxytropis spp. and Astragalus spp.), including a 3 kb inversion, two large insertions (>1 kb), significant modifications of the accD gene, and an overall larger size.SignificanceTourism accounts for roughly 10% of global gross domestic product, with nature-based tourism its fastest-growing sector in the past 10 years. Nature-based tourism can theoretically contribute to local and sustainable development by creating attractive livelihoods that support biodiversity conservation, but whether tourists prefer to visit more biodiverse destinations is poorly understood. We examine this question in Costa Rica and find that more biodiverse places tend indeed to attract more tourists, especially where there is infrastructure that makes these places more accessible. Safeguarding terrestrial biodiversity is critical to preserving the substantial economic benefits that countries derive from tourism. Investments in both biodiversity conservation and infrastructure are needed to allow biodiverse countries to rely on tourism for their sustainable development.
