The genus Baylisascaris (order Ascaridida) includes numerous relatively host-specific nematodes, which are common in intestines of wild mammals. Some of them may have impact on veterinary and public health, as their larvae have the potential to cause visceral, ocular, and/or neural larva migrans in a wide range of mammals, birds, and humans. Baylisascaris transfuga is a parasite occurring in a range of bear species throughout the world. We present the current data on B. transfuga occurrence in brown bears from a relatively restricted territory of the Poľana Protected Landscape Area in Central Slovakia, obtained by traditional methods (faecal examination, morphology)...

The emergence of queens and workers from solitary antecedents mark a major evolutionary transition in the history of life. The solitary progressive provisioning wasp Synagris cornuta, a member of the subfamily Eumeninae (basal to eusocial vespid wasps), alternates between behavioral states characterized as queenlike and worker-like. Akin to a queen in eusocial wasps, a S. cornuta female initiates construction of a cell into which she oviposits and then, similar to a worker, cares for the brood as it develops...

Long-term exposure to methyl-mercury has deleterious effects on avian reproduction. However, little is known about whether exposure to mercury solely during embryonic and juvenile development can have long-lasting effects on subsequent reproductive performance as adults. Birds that hatch on contaminated sites, but disperse elsewhere, will be exposed only during development. Hence, it is important to understand the reproductive consequences of avian exposure to methyl-mercury during early life. Accordingly, in this experiment, domesticated zebra finches (Taeniopygia guttata) were exposed to dietary methyl-mercury (1...

Chlamydia is considered as one of the most widely prevalent zoonotic pathogens. It can spread from infected birds to human beings through direct or indirect contact with fecal shedding of Chlamydia. However, data concerning prevalence and genotypes of Chlamydia in pigeons are limited. In the present study, a total of 963 serum samples was collected from Jilin Province, Liaoning Province, and Inner Mongolia Autonomous Region (IMAR) in China between August 2015 and December 2016 and the seroprevalence for Chlamydia was analyzed by indirect hemagglutination assay test...

Fish early life stage (FELS) tests (OECD test guideline 210) are widely conducted to estimate chronic fish toxicity. In these tests, fish are exposed from the embryonic to the juvenile life stage. In order to analyse whether certain modes of action are related to high toxic ratios (TR, i.e., ratios between experimental effect and baseline toxicity) and/or acute-to-chronic ratios (ACR) in the FELS test effect concentrations for 183 compounds were extracted from the US EPA ecotoxicity database. Analysis of effect concentration of narcotic compounds indicated that baseline toxicity could be observed in the FELS test at similar concentrations as in acute fish toxicity test...

This study evaluated efficacy and toxicity of the pyrazinoisoquinoline anthelmintic praziquantel (PZQ) in barbel infected with metacercariae of Diplostomum spathaceum and adult Pomphorhynchus laevis, and assessed antioxidant biomarkers and the lipid peroxidation response in juvenile barbel post-treatment. The estimated 96-hr LC50 of PZQ was 28.6 mg/L. For evaluation of efficacy, barbel naturally infected with D. spathaceum were exposed to a 10 and 20 mg/L PZQ 4-day bath treatment. Both concentrations were 100% effective against D...

Parkin for more than a decade has been portrayed as a neuroprotector gene is now increasingly emerging as a multifaceted gene that can exert entirely opposite effects i.e., both cell proliferation and apoptosis. Parkinson's disease, a neurological disease, progresses due to excess in cell death, while, in case of cancer, cell death normally fails to occur. Parkin, an E3 ubiquitin ligase, was first identified as a gene implicated in autosomal recessive juvenile Parkinsonism, but several evidences indicate that Parkin is a tumor suppressor gene, involved in a variety of cancers...

Despite the growth in knowledge about the effects of a warming Arctic on its cold-adapted species, the mechanisms by which these changes affect animal populations remain poorly understood. Increasing temperatures, declining sea ice and altered wind and precipitation patterns all may affect the fitness and abundance of species through multiple direct and indirect pathways. Here we demonstrate previously unknown effects of rain-on-snow (ROS) events, winter precipitation, and ice tidal surges on the Arctic's largest land mammal...

OBJECTIVES: Depending on patient age at onset, absence epilepsy is subdivided into childhood and juvenile forms. Absence seizures can occur several times per day (pyknoleptic course) or less frequently than daily (non-pyknoleptic course). Seizures typically terminate before adulthood, but a quarter of patients need ongoing treatment beyond adolescence. Little is known about their long-term seizure and psychosocial outcome. METHODS: Files of 135 outpatients with absence epilepsy (76 females; 123 had additional generalised tonic-clonic seizures) were retrospectively analysed after a median follow-up of 45...

BACKGROUND: For many fish species, retinal function changes between life history stages as part of an encoded developmental program. Retinal change is also known to exhibit plasticity because retinal form and function can be influenced by light exposure over the course of development. Aside from studies of gene expression, it remains largely unknown whether retinal plasticity can provide functional responses to short-term changes in environmental light quality. The aim of this study was to determine whether the structure and function of the fish retina can change in response to altered light intensity and spectrum-not over the course of a developmental regime, but over shorter time periods relevant to marine habitat disturbance...

BACKGROUND: Schistosomiasis caused by Schistosoma japonicum is among the most serious endemic zoonoses in China. To study interactions between schistosomula, the pre-adult juvenile stage, and hosts, it is important to study the functions of key genes involved in schistosomula growth and development. Programmed cell death protein 10 (pcdp10) is an important apoptosis-related gene with various biological functions. This study described the molecular characterization of S. japonicum PCDP10 (SjPCDP10) and evaluated its functions in schistosomula...

Argentina has two endemic areas of paracoccidioidomycosis (PCM). Bordering Paraguay and Brazil, Northeast Argentina (NEA) comprises the area with the highest incidence where the chronic adult clinical form has historically been reported. Juvenile form in children and adolescents is rare in this area since only one case was reported in the last 10 years. Despite this, between 2010 and 2012, several cases of acute/subacute clinical forms in children aged 10 to 16 (median 12) were detected. In the last decade, the NEA region has been exposed to ecological variations as consequences of certain climatic and anthropogenic changes, including El Niño-Southern Oscillation phenomenon during 2009, and deforestation...

miR-9 is an evolutionarily conserved miRNA that is abundantly expressed in Area X, a basal ganglia nucleus required for vocal learning in songbirds. Here, we report that overexpression of miR-9 in Area X of juvenile zebra finches impairs developmental vocal learning, resulting in a song with syllable omission, reduced similarity to the tutor song, and altered acoustic features. miR-9 overexpression in juveniles also leads to more variable song performance in adulthood, and abolishes social context-dependent modulation of song variability...

Systemic juvenile idiopathic arthritis (SJIA) is a severe childhood arthropathy with features of autoinflammation. Monocytes and macrophages in SJIA have a complex phenotype with both pro- and anti-inflammatory properties that combine features of several well characterized in vitro conditions used to activate macrophages. An important anti-inflammatory phenotype is expression of CD163, a scavenger receptor that sequesters toxic pro-inflammatory complexes that is highly expressed in both active SJIA and macrophage activation syndrome (MAS)...

Plate tectonics and associated subduction are unique to the Earth. Studies of Archean rocks show significant changes in composition and structural style around 3.0 to 2.5 Ga that are related to changing tectonic regime, possibly associated with the onset of subduction. Whole rock Hf isotope systematics of black shales from the Australian Pilbara craton, selected to exclude detrital zircon components, are employed to evaluate the evolution of the Archean crust. This approach avoids limitations of Hf-in-zircon analyses, which only provide input from rocks of sufficient Zr-concentration, and therefore usually represent domains that already underwent a degree of differentiation...
