Amyloodiniosis represents a major bottleneck for semi-intensive aquaculture production in Southern Europe, causing extremely high mortalities. Amyloodinium ocellatum is a parasitic dinoflagellate that can infest almost all fish, crustacean and bivalves that live within its ecological range. Fish mortalities are usually attributed to anoxia, associated with serious gill hyperplasia, inflammation, haemorrhage and necrosis in heavy infestations; or with osmoregulatory impairment and secondary microbial infections due to severe epithelial damage in mild infestation...

The field of firearms and toolmark analysis has encountered deep scrutiny of late, stemming from a handful of voices, primarily in the law and statistical communities. While strong scrutiny is a healthy and necessary part of any scientific endeavor, much of the current criticism leveled at firearm and toolmark analysis is, at best, misinformed and, at worst, punditry. One of the most persistent criticisms stems from the view that as the field lacks quantified random match probability data (or at least a firm statistical model) with which to calculate the probability of a false match, all expert testimony concerning firearm and toolmark identification or source attribution is unreliable and should be ruled inadmissible...

STUDY QUESTION: What are the chromosome segregation errors in human oocyte meiosis-I that may underlie oocyte aneuploidy? SUMMARY ANSWER: Multiple modes of chromosome segregation error were observed, including tri-directional anaphases, which we attribute to loss of bipolar spindle structure at anaphase-I. WHAT IS KNOWN ALREADY: Oocyte aneuploidy is common and associated with infertility, but mechanistic information on the chromosome segregation errors underlying these defects is scarce...

Gene codon optimization may be impaired by the misinterpretation of frequency and optimality of codons. Although recent studies have revealed the effects of codon usage bias (CUB) on protein biosynthesis, an integrated perspective of the biological role of individual codons remains unknown. Unlike other previous studies, we show, through an integrated framework that attributes of codons such as frequency, optimality and positional dependency should be combined to unveil individual codon contribution for protein biosynthesis...

This study evaluates the environmental impacts of biorefinery products using consequential (CLCA) and attributional (ALCA) life cycle assessment (LCA) approaches. Within ALCA, economic allocation method was used to distribute impacts among the main products and the coproducts, whereas within the CLCA system expansion was adopted to avoid allocation. The study seeks to answer the questions (i) what is the environmental impacts of process integration?, and (ii) do CLCA and ALCA lead to different conclusions when applied to biorefinery?...

All of these days, residues of herbicides such as glyphosate are widely distributed in the environment. The ubiquitous use of glyphosate has drawn extensive attention to its toxicity as an organic pollutant. In this study, we employed larval zebrafish as an animal model to evaluate the effect of different concentrations of glyphosate on early development via morphological, biomechanics, behavioral and physiological analyses. Morphological results showed that an obvious delay occurred in the epiboly process and body length, eye and head area were reduced at concentrations higher than 10 mg/L...

Using a rich Norwegian longitudinal data set, this study explores the effects of different social capital variables on the probability of cigarette smoking. There are four social capital variables available in two waves of our data set. Our results based on probit (and OLS) analyses (with municipality fixed-effects) show that the likelihood of smoking participation is negatively and significantly associated with social capital attributes, namely, community trust (-0.017), participation in organizational activities (-0...

BACKGROUND: Recent studies suggest that parents' awareness of their offspring's schizophrenia could influence their offspring's insight. Low patient insight is linked to impairment of specific cognitive abilities, and biological parents of schizophrenia patients have impaired capacities in these same domains. However, little is known about what specific socio-demographic, affective or cognitive factors may influence biological parents' awareness of their offspring's disease. METHOD: Data were drawn from 41 patient-parent dyads...

Petroleum refineries generate large amounts of wastewaters, which can have acute/chronic toxicity toward aquatic organisms. Previous studies have shown that many contaminants can be responsible for this toxicity, among them ammonia, sulfide, cyanide, phenols and hydrocarbons. In the study reported herein, the cause of the chronic toxicity of a biotreated petroleum refinery wastewater was investigated by applying the TIE methodology using the microcrustacean Ceriodaphnia dubia. Five samples were analyzed, and the results suggest that copper is the primary toxicant, showing a strong correlation with wastewater toxicity in Phase III...

Most information on seagrass carbon burial derives from point measurements, which are sometimes scaled by meadow area to estimate carbon stocks; however, sediment organic carbon (Corg) concentrations may vary with distance from the meadow edge, resulting in spatial gradients that affect the accuracy of stock estimates. We mapped sediment Corg concentrations throughout a large (6 km2) restored seagrass meadow to determine whether Corg distribution patterns exist at different spatial scales. The meadow originated from ≤1-acre plots seeded between 2001 and 2004, so we expected Corg to vary spatially according to the known meadow age at sample sites and with proximity to the meadow edge...

The definition of sepsis was updated to sepsis-3 in February 2016. However, the performance of the previous and new definition of sepsis remains unclear in China. This was a retrospective multicenter study in 6 ICUs from 5 university-affiliated hospitals to compare the performance between sepsis-1 and sepsis-3 in China. From May 1, 2016 to June 1, 2016, 496 patients were enrolled consecutively. Data were extracted from the electronic clinical records. We evaluated the performance of sepsis-1 and sepsis-3 by measuring the area under the receiver operating characteristic curves (AUROC) to predict 28-day mortality rates...

AIM: National and international healthcare agencies and organizations typically attribute slow or haphazard growth in hospice and palliative care in developing countries to various resource constraints. This study provides evidence of the substantial and widening gap between policy advocacy and individual decision-making concerning end-of-life care. It does so by establishing the incentives and risks that underlie choices of patients and providers against the relative scarcity of hospices in these countries...

OBJECTIVE: Despite advances in cervical cancer prevention and diagnosis, outcomes for patients given a diagnosis of advanced and recurrent disease are poor. In the GOG240 trial, the addition of bevacizumab to paclitaxel-topotecan or paclitaxel-cisplatin has been shown to prolong survival compared with paclitaxel-topotecan or paclitaxel-cisplatin in patients with persistent, recurrent, or metastatic disease. However, standards of care vary between regions and countries. The purpose of this systematic review and network meta-analysis was to enable a comparison between bevacizumab + chemotherapy with multiple monotherapy or combination chemotherapy regimens in the treatment for women with advanced, recurrent, or persistent cervical cancer...

Disordered eating is common among young women, but rates of help-seeking are remarkably low. Studies attempting to understand how disordered eating is perceived by young women have exposed participants to fictional vignettes that describe characters exhibiting eating pathologies, and assessed beliefs about the women's issues. These studies have informed our understanding of how young women perceive disordered eating in other women, but do not address the question of how disordered eating is perceived in oneself...

Structural identification of double-walled carbon nanotubes (DWNT) is presented through a robust procedure based on the latest generation of transmission electron microscope, making possible a statistical analysis based on numerous nano-objects. This approach reveals that inner and outer tubes of DWNTs are not randomly oriented, suggesting the existence of a mechanical coupling between the two concentric walls. With the support of atomic-scale modeling, we attribute it to the presence of incommensurate domains whose structures depend on the diameters and helicities of both tubes, and where inner tubes try to achieve a local stacking orientation to reduce strain effects...
