High cost of healthy foods could be a barrier to healthy eating. We aimed to examine the association between dietary cost and adherence to the Mediterranean diet in a non-Mediterranean country. We evaluated cross-sectional data from 12 417 adults in the UK Fenland Study. Responses to 130-item FFQ were used to calculate a Mediterranean diet score (MDS). Dietary cost was estimated by matching food consumption data with retail prices of five major supermarkets. Using multivariable-adjusted linear regression, we examined the association of MDS and individual foods with dietary cost in absolute and relative scales...

Nutritional deficit of n-3 polyunsaturated fatty acids (PUFAs) is closely related to cognitive impairment and depression in later life. Cognitive impairment and depression lead to comorbidities, such as metabolic syndrome, in elderly people. The aim of this study is to evaluate the effects of dietary n-3 PUFAs on cognition and depressive-like behavior in an accelerated senescence rat model with prediabetic status. Rats were cotreated with d-gal and sucrose solution for 7 months and then fed fish-oil- or flaxseed-oil-rich diets for 3 months...

It is generally accepted that climate change will stress coldwater species like Pacific salmon. However, it is unclear what aspect of altered thermal regimes (e.g., warmer winters, springs, summers, or increased variability) will have the greatest effect, and what role the spatial properties of river networks play. Thermally diverse habitats may afford protection from climate change by providing opportunities for aquatic organisms to find and use habitats with optimal conditions for growth. We hypothesized that climate-altered thermal regimes will change growth and timing of life history events such as emergence or migration but that changes will be moderated in topologically complex stream networks where opportunities to thermoregulate are more readily available to mobile animals...

The aim of this study was to examine the impact of regional diets on the health of the poor in mid-Victorian Britain. Contemporary surveys of regional diets and living condition were reviewed. This information was compared with mortality data from Britain over the same period. Although there was an overall improvement in life expectancy during the latter part of the 19th century, there were large regional differences in lifestyle, diet and mortality rates. Dietary surveys showed that the poor labouring population in isolated rural areas of England, in the mainland and islands of Scotland and in the west of Ireland enjoyed the most nutritious diets...

Long non-coding RNAs (lncRNAs) have been reported to be of great importance in the formation and progression of a wide range of human carcinomas including prostate cancer (PCa). Among them, PCAT3 and PCAT9 have been identified as two prostate tissue-specific lncRNAs and are up-regulated in PCa. However, their roles in the biological characteristics of PCa have not been fully elucidated. In the present study, our data revealed that knockdown of PCAT3 and PCAT9 suppressed cellular proliferation, invasion, migration, angiogenesis and stemness in androgen-dependent LNCaP and 22Rv1 cells...

Schizolecis is a monotypic genus of Siluriformes widely distributed throughout isolated coastal drainages of southeastern Brazil. Previous studies have shown that fish groups found in isolated river basins tend to differentiate over time in the absence of gene flow, resulting in allopatric speciation. In this study, we used partial sequences of the mitochondrial gene COI with the analysis of the General Mixed Yule Coalescent model (GMYC) and the Automatic Barcode Gap Discovery (ABGD) for single locus species delimitation, and a Principal Component Analysis (PCA) of external morphology to test the hypothesis that Schizolecis guntheri is a complex of species...

A new pycnodont fish from the early-mid Cenomanian, Late Cretaceous, of the 'Ein Yabrud quarry near the village of Beit Eil in Israel is the first pycnodont fish to be described from this locality. Due to the locality where it was found, Scalacurvithys naishi gen. et sp. nov. is considered an inhabitant of reefal waters interspersed with lagoons in the eastern Tethys Sea. Scalacurvichthys naishi is notable for its protruding, hook-shaped first dorsal ridge scale above a large triangular dermatocranium, a deeply sloped and antero-posteriorly shortened skull and bifurcated cloacal scales...

In mammals, beclin-1 is a key player that regulates autophagic activity. In fish, the immune function of beclin-1 is essentially unknown. In this study, we analyzed the involvement of tongue sole (Cynoglossus semilaevis) beclin-1 (named CsBECN1) in antibacterial immunity. CsBECN1 is composed of 451 amino acid residues and shares 84.5-95.1% overall sequence identities with other teleost beclin-1. CsBECN1 possesses a typical Bcl-2 homology domain 3 and an Atg6 domain. Expression of CsBECN1 occurred in multiple tissues and was upregulated during bacterial infection...

The Notacanthiformes is an ancient group of deep-sea ray-finned fishes comprising 27 species in two families; Halosauridae and Notacanthidae. Although many studies have tried to reconstruct the phylogenetic relationships among the major clades of Elopomorpha, little is known about the evolutionary history of notacanthiforms. Molecular and morphological data were used to test previous hypotheses regarding the phylogenetic relationships among notacanthiform taxa, and to unravel the origin and evolution of this group...

The use of commercial pesticides combinations increases the risk of intoxication in non-target aquatic organisms. Here, we investigate the potential of a commercial pesticide formulation containing (CYP) plus chlopyrifos (CPF) to induce oxidative damage on two fish species (common carp and zebrafish). Carp and zebrafish were exposed for 96 h under laboratory conditions. Fish were divided in three different groups: CTL, 0.3 μg L-1 or 0.6 μg L-1 of CYP and 0.5 or 1 μg L-1 of CPF in commercial formulation...

Determining the biotransformation potential of commercial chemicals is critical for estimating their persistence in the aquatic environment. In vitro systems are becoming increasingly important as screening methods for assessing the potential for chemical metabolism. Depletion rate constants (kd ) for several organic chemicals with high octanol-water partition coefficient (Kow ) values (9-methylanthracene, benzo(a)pyrene, chrysene, and PCB-153) in rainbow trout hepatocytes were determined to estimate biotransformation rate constants (kMET ) that were used in fish bioconcentration factor (BCF) models...

Acute promyelocytic leukaemia with PML-RARA fusion is usually associated with the t(15;17)(q24.1;q21.1) translocation but may also arise from complex or cryptic rearrangements. The fusion usually resides on chromosome 15 but occasionally on others. We describe a cryptic PML-RARA fusion within a novel chromosome 17 rearrangement. We performed interphase fluorescence in situ hybridisation (FISH) using a dual-fusion PML-RARA probe, followed by reverse transcriptase-polymerase chain reaction (RT-PCR) for PML-RARA, karyotyping, and metaphase FISH using RARA break-apart, locus-specific, and subtelomere probes for chromosome 17...

We report here a 74-year-old male who was seen for recurrent respiratory infections, fatigue, and weight loss in November 2016. Bone marrow biopsy showed 90% involvement by plasma cell myeloma (PCM) [90% plasma cells, 40% cellular bone marrow]. Cytogenetic analysis of the bone marrow showed a complex karyotype described as: 53,Y,add(X)(p22.1),del(1)(p13p22),+3,add(3)(p13),add(4)(p12),+6,del(6)(q13q25),t(8;22)(q24.1;q11.2),+9,+11,+15,+15,+21[7]/46,XY[13]. This particular pattern with deletion 1p, deletion 6q, and a t(8;22)(q24;q11...

Selenium (Se) is considered an essential trace element, involved in important physiological and metabolic functions for all vertebrate species. Fish require dietary concentrations of 0.1-0.5 μg Se/g dry mass (d.m.) to maintain normal physiological and selenoprotein function, however concentrations exceeding 3 μg/g d.m. have been shown to cause toxicity. As Se is reported to have a narrow margin between essentiality and toxicity, there is growing concern surrounding the adverse effects of elevated Se exposure caused by anthropogenic activities...

Zoonotic fish-borne nematodes are a significant and growing global health concern. However, in Australia their occurrence and geographical distribution are not well known. Moreton Bay in Queensland, Australia, is a popular tourist destination for domestic and international visitors where seafood is a popular food item. The aim of this study was to determine the occurrence of zoonotic nematodes within four commercially significant teleost fish species from Moreton Bay; Surf Bream, Sea Mullet, Yellow-Fin Tripod fish and Gold-Lined Sea Bream...

Marine plastic pollution is present in all oceans, including remote oceanic islands. Despite the increasing number of articles on plastic pollution in the last years, there is still a lack of studies in islands, that are biodiversity hotspots when compared to the surrounding ocean, and even other recognized highly biodiverse marine environments. Articles published in the peer reviewed literature (N = 20) were analysed according to the presence of macro (>5 mm) and microplastics (<5 mm) on beaches and the marine habitats immediately adjacent to 31 islands of the Atlantic Ocean and Caribbean Sea...

The present study aimed to evaluate the individual and combined effects of Lactobacillus rhamnosus (LR) JCM1136 and Lactococcus lactis subsp. lactis (LL) JCM5805 on the growth, intestinal microbiota, intestinal morphology, immune response and disease resistance of juvenile Nile tilapia (Oreochromis niloticus). A total of 720 apparently healthy juvenile Nile tilapia (0.20 ± 0.05 g) were randomly divided into four equal groups. Fish were fed with a basal diet (CK) supplemented with JCM1136 (LR), JCM5805 (LL), and JCM1136 + JCM5805 (LR+LL) at 1 × 108  CFU/g basal diet for 6 weeks, followed by a basal diet for 1 week...

The mammalian sterile 20-like (MST) family, which belongs to the serine/threonine protein kinase superfamily, has five members that can be found in mammals: STK3 (also called MST2), STK4 (MST1), STK24 (MST3), STK25 (YSK1 or SOK1), and STK26 (MST4). The MST kinases have key roles in apoptosis, immune regulation, inflammatory responses, cancer, and cell proliferation in mammals, whereas the roles and transcriptional regulatory mechanism of these kinases in teleost fish are still unclear. In this study, four STK genes (CiSTK3, CiSTK24, CiSTK25, and CiSTK26) were cloned and analyzed in grass carp (Ctenopharyngodon idella)...
