Despite a substantial increase in our knowledge of the biodiversity and evolution of vertebrate RNA viruses, far less is known about the diversity, evolution and origin of RNA viruses across the diverse phylogenetic range of viruses, and particularly in healthy animals that are often only rarely utilized for virological sampling. Fortunately, recent advances in virus discovery using metagenomic approaches are beginning to reveal a multitude of RNA viruses in vertebrates other than birds and mammals. In particular, fish harbor a remarkable array of RNA viruses, including the relatives of important pathogens...

Midkine (Mdk)is a cytokine involved in controlling tissue repair and new tissue development, and regulating inflammation involved in several signaling pathway, such as the mitogen-activated protein kinase (MAPK) and phosphatidyl inositol 3-kinase (PI3K)/AKT pathways. But the role of Mdk in the development of Cynoglossus semilaevis is poorly understood. In this study, the Midkine of C. semilaevis (CsMdk) was cloned, and its spatiotemporal expression pattern and structural characteristics were analyzed. Furthermore, the essential genes related to nervous system development and germ layer formation marker gene were identified by qRT-PCR and in situ hybridization after overexpression the CsMdk via zebrafish model...

Fishes of the elasmobranch superorder Batoidea and the basal teleost superorder Elopomorpha were assessed for blood flukes (Digenea: Aporocotylidae) during a parasitological survey conducted in Moreton Bay, Queensland, Australia. A new blood fluke genus and species, Ogawaia glaucostegi n. gen., n. sp., is described from the Giant shovelnose ray, Glaucostegus typus (Anonymous [Bennett]) (Rhinopristiformes: Glaucostegidae). Ogawaia glaucostegi differs from species of all other aporocotylid genera in the combination of the absence of anterior caeca and oral sucker, having a pronounced distal oesophageal chamber, a strongly coiled testis and a common genital pore...

Lake whitefish (Coregonus clupeaformis) utilize overwintering embryonic development (up to 180 days), and such stenothermic, cold-water embryos may be particularly susceptible to thermal shifts. We incubated whitefish embryos in temperature treatments that were constant temperature (2.0 ± 0.1 °C, 5.0 ± 0.1 °C, and 8.0 ± 0.1 °C; mean ± SD) or variable temperature (VT, mean = 5.0 ± 0.3 °C). In the VT, a daily 2 °C temperature change followed a continuous pattern throughout development: 2-4-6-8-6-4-2 °C...

In this study, a long neuropeptide F receptor of the blood-feeding hemipteran, Rhodnius prolixus (RhoprNPFR) has been cloned and characterized. Approximately 70% of the RhoprNPFR deduced protein sequence is identical to that of other hemipteran NPFRs. RhoprNPFR has seven highly-conserved transmembrane domains, two cysteine residues in the 2nd and 3rd extracellular loops that likely form a disulfide bond integral for maintaining the structure of the receptor, and a conserved DRY motif after the third transmembrane domain...

In many fish species, sperm cryopreservation has deleterious effects and leads to a significant decrease in spermatozoa viability. However, the effect of cryopreservation on sperm cells that survive this process and are still viable is not fully understood. The objective of this study was to compare the viability and proteomes of fresh and cryopreserved sterlet (Acipenser ruthenus) sperm samples before and after live-dead cell separation using Percoll density gradient centrifugation. Both fresh and cryopreserved sperm samples were divided into two groups (with or without application of Percoll separation)...

It is well known that essential proteins play an extremely important role in controlling cellular activities in living organisms. Identifying essential proteins from protein protein interaction (PPI) networks is conducive to the understanding of cellular functions and molecular mechanisms. Hitherto, many essential proteins detection methods have been proposed. Nevertheless, those existing identification methods are not satisfactory because of low efficiency and low sensitivity to noisy data. This paper presents a novel computational approach based on artificial fish swarm optimization for essential proteins prediction in PPI networks (called AFSO_EP)...

Diet assimilation efficiencies (AEs) of polychlorinated biphenyls (PCBs) absorbed to microplastics and food were determined in goldfish (Carassius auratus). Microplastics were spiked with 14 environmentally rare PCBs and incorporated into fish pellets previously spiked with a technical PCB mixture (Aroclor 1254). Five diet treatments were created having microplastic contents of 0, 5, 10, 15, 20 and 25% and fed to fish within 24 h of the diet creation. Fish from each treatment were fed a microplastic amended food pellet and PCB AEs were determined by mass balance...

Background and Aims: Orchidaceae is a large plant family, and its extraordinary adaptations may have guaranteed its evolutionary success. Flavonoids are a group of secondary metabolites that mediate plant acclimation to challenge environments. Chalcone synthase (CHS) catalyses the initial step in the flavonoid biosynthetic pathway. This is the first chromosome-level investigation of the CHS gene family in Phalaenopsis aphrodite and was conducted to elucidate if divergence of this gene family is associated with chromosome evolution...

Primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT) and primary cutaneous follicle center lymphoma (PCFCL) are cutaneous B-cell lymphomas (CBCL) with different clinical characteristics and behavior. PCDLBCL-LT is the most aggressive CBCL with a relatively poor prognosis. In nodal diffuse large B-cell lymphoma (DLBCL), rearrangements of the MYC gene, especially in combination with a second hit in BCL2 and/or BCL6, and double protein expression of MYC and BCL2 (DE) are adverse prognostic factors...

Atypical RhoV GTPase (Chp/Wrch-2) is a member of the human Rho GTPase family, which belongs to the superfamily of Ras-related small GTPases. The biological functions of RhoV, regulation of its activity, and mechanisms of its action remain largely unexplored. Rho GTPases regulate a wide range of cellular processes by interacting with protein targets called effectors. Several putative RhoV effectors have been identified, including protein kinases of the Pak (p21-activated kinase) family: Pak1, Pak2, Pak4, and Pak6...

Concrete structures develop biofilms when exposed to various environments. At a certain stage, the microbial films destroy the concrete structures leading to significant deterioration. Culture-dependent techniques give an incomplete picture of the microbial communities on the concrete surface. Culture independent techniques or molecular biological tools pave a new way to analyze microbial communities involved in concrete biodeterioration. This study highlights the need to 'build' a database, for Microbiologically Influenced Concrete Corrosion (MICC) involving microbial groups that are being identified using culture dependent and independent techniques...

Juveniles of the cooperatively-breeding cichlid fish Neolamprologus pulcher either consistently provide help in form of alloparental egg care ('cleaners') or consistently abstain from helping ('non-cleaners'). These phenotypes are not based on heritable genetic differences. Instead they arise during ontogeny, which should lead to differences in brain structure or physiology, a currently untested prediction. We compared brain gene expression profiles of cleaners and non-cleaners in two experimental conditions, a helping opportunity and a control condition...
