The advantage of CT scans and 3D visualizations in the analysis of three child mummies from the Graeco-Roman Period.

Three child mummies from the Graeco-Roman Period (332 BCE - c. 395 CE) were examined using CT scans and 3D visualizations generated with Vitrea 2 and MIMICS graphic workstations with the aim of comparing the results with previous X-ray examinations performed by Dawson and Gray in 1968. Although the previous analyses reported that the children had been excerebrated and eviscerated, no evidence of incisions or breaches of the cranial cavity were found; 3D visualizations were generated showing the brain and the internal organs to be in situ.

Aberrant synaptic integration in adult lamina I projection neurons following neonatal tissue damage.

Mounting evidence suggests that neonatal tissue damage evokes alterations in spinal pain reflexes which persist into adulthood. However, less is known about potential concomitant effects on the transmission of nociceptive information to the brain, as the degree to which early injury modulates synaptic integration and membrane excitability in mature spinal projection neurons remains unclear. Here we demonstrate that neonatal surgical injury leads to a significant shift in the balance between synaptic excitation and inhibition onto identified lamina I projection neurons of the adult mouse spinal cord.

Independent evaluation of a canine Echinococcosis Control Programme in Hobukesar County, Xinjiang, China.

The Xinjiang Uyghur Autonomous Region in northwest China is one of the world's most important foci for cystic echinococcosis. Domestic dogs are the main source for human infection, and previous studies in Xinjiang have found a canine Echinococcus spp. coproELISA prevalence of between 36% and 41%.

Annotation of proteins of unknown function: initial enzyme results.

Working with a combination of ProMOL (a plugin for PyMOL that searches a library of enzymatic motifs for local structural homologs), BLAST and Pfam (servers that identify global sequence homologs), and Dali (a server that identifies global structural homologs), we have begun the process of assigning functional annotations to the approximately 3,500 structures in the Protein Data Bank that are currently classified as having "unknown function". Using a limited template library of 388 motifs, over 500 promising in silico matches have been identified by ProMOL, among which 65 exceptionally good matches have been identified. The characteristics of the exceptionally good matches are discussed.

Role of balloon-assisted cholangioscopy in a multiethnic cohort to assess complex biliary disease (with videos).

Background: Cholangioscopy is used to diagnose and treat various biliary lesions. Balloon-assisted cholangioscopy (BAC) has mostly been reported in Asian patients with large bile ducts.

Objective: To assess the feasibility and accuracy of performing BAC in complex biliary diseases in Australian patients.

Echinococcus equinus and Echinococcus granulosus sensu stricto from the United Kingdom: genetic diversity and haplotypic variation.

Cystic echinococcosis is endemic in Europe including the United Kingdom. However, information on the molecular epidemiology of Echinococcus spp. from the United Kingdom is limited.

Prevalence of Toxoplasma gondii in localized populations of Apodemus sylvaticus is linked to population genotype not to population location.

Toxoplasma gondii is a globally distributed parasite infecting humans and warm-blooded animals. Although many surveys have been conducted for T. gondii infection in mammals, little is known about the detailed distribution in localized natural populations.

A random forest approach for predicting the presence of intermediate host . presence in relation to landscape characteristics in western China.

Understanding distribution patterns of hosts implicated in the transmission of zoonotic disease remains a key goal of parasitology. Here, random forests are employed to model spatial patterns of the presence of the plateau pika (.) small mammal intermediate host for the parasitic tapeworm which is responsible for a significant burden of human zoonoses in western China.

Post-encystment/established immunity in cystic echinococcosis: is it really that simple?

In 1982, Rickard & Williams stated that immunity to larval taeniid cestodes could be divided into two different phases: the establishment phase, operating against oncospheres, and the established phase, operating against established metacestodes in the tissues. These concepts were largely based on experimental and veterinary data. As a result of subsequent research combined with clinical data, we can consider that, for metacestodes of Echinococcus spp, a single established phase is probably too simple a concept.

Genetic variability and haplotypes of Echinococcus isolates from Tunisia.

Background: The species/genotypes of Echinococcus infecting a range of intermediate, canid and human hosts were examined as well as the intraspecific variation and population structure of Echinococcus granulosus sensu lato (s.l.) within these hosts.

Evaluating the Health "Hubs and Spokes" interprofessional placements in rural New South Wales, Australia.

Unlabelled: Australia has been relatively slow in adopting interprofessional learning (IPL) to prepare health professional students for future collaborative professional practice. A collaborative project between two universities placed senior health professional students in IPL teams in rural southeast New South Wales, Australia, to work on small, locally relevant projects with guidance from locally appointed IPL facilitators. This paper reports on the initial stages of an evaluation of this rural-based IPL intervention using the modified Freeth/Kirkpatrick's 4-level evaluation model.

Prevalence and risk factors for echinococcal infection in a rural area of northern Chile: a household-based cross-sectional study.

Background: Hydatidosis is a zoonotic disease of worldwide distribution caused by Echinococcus granulosus. Our study aimed to determine the prevalence of human and canine echinococcosis as well as the associated risk factors in a rural area of the Limarí province in northern Chile.

Methodology/principal Findings: A cross-sectional study was conducted between August and November 2009 using a stratified sampling design in each of the five districts of the province.

Helminth parasites in the endangered Ethiopian wolf, Canis simensis.

Ethiopian wolves, Canis simensis, are an endangered carnivore endemic to the Ethiopian highlands. Although previous studies have focused on aspects of Ethiopian wolf biology, including diet, territoriality, reproduction and infectious diseases such as rabies, little is known of their helminth parasites. In the current study, faecal samples were collected from 94 wild Ethiopian wolves in the Bale Mountains of southern Ethiopia, between August 2008 and February 2010, and were screened for the presence of helminth eggs using a semi-quantitative volumetric dilution method with microscopy.

Modelling the transmission dynamics of cystic echinococcosis in donkeys of different ages from Tunisia.

During the period from March 2006 to July 2009 a total of 2040 slaughtered donkeys were examined for cystic echinococcosis (CE). CE prevalence in donkeys was 8.48% and the infection pressure (0.

Taenia saginata taeniosis: copro-antigen time-course in a voluntary self-infection.

Human taeniosis due to Taenia saginata is cosmopolitan where beef is consumed; however, there is little or no information on the symptomatology over the early time-course of human infection. Copro-antigen detection is very useful in community screening for human taeniosis, particularly for T. solium, but there are no data on copro-antigen detection in pre-patent infection.

Naturally occurring Toll-like receptor 11 (TLR11) and Toll-like receptor 12 (TLR12) polymorphisms are not associated with Toxoplasma gondii infection in wild wood mice.

Toxoplasma gondii is a highly successful parasite with a worldwide prevalence. Small rodents are the main intermediate hosts, and there is growing evidence that T. gondii modifies their behaviour.

Profiling hepatic microRNAs in zebrafish: fluoxetine exposure mimics a fasting response that targets AMP-activated protein kinase (AMPK).

This study examined the similarities in microRNA profiles between fasted and fluoxetine (FLX) exposed zebrafish and downstream target transcripts and biological pathways. Using a custom designed microarray targeting 270 zebrafish miRNAs, we identified 9 differentially expressed miRNAs targeting transcripts in biological pathways associated with anabolic metabolism, such as adipogenesis, cholesterol biosynthesis, triacylglycerol synthesis, and insulin signaling. Exposure of female zebrafish to 540 ng/L FLX, an environmentally relevant concentration and a known metabolic repressor, increased specific miRNAs indicating greater inhibition of these pathways in spite of continued feeding.

Myopericytoma of the parotid region treated by extracapsular dissection.

Myopericytoma (MPC) is a vascular neoplasm exhibiting differentiation towards perivascular cells. Variable cytoarchitechtural features are visible within MPC, and there is much overlap between MPC, myofibroma and glomus tumours. MPC have a local recurrence rate of 10-20% and malignancy has been described in a few published cases.

Estimation of protein function using template-based alignment of enzyme active sites.

Background: The accumulation of protein structural data occurs more rapidly than it can be characterized by traditional laboratory means. This has motivated widespread efforts to predict enzyme function computationally. The most useful/accurate strategies employed to date are based on the detection of motifs in novel structures that correspond to a specific function.

Divergent hypoxia tolerance in adult males and females of the plainfin midshipman (Porichthys notatus).

In the summer, the plainfin midshipman (Poricththys notatus) migrates to reproduce in the nearshore environment, where oxygen levels are influenced by the tidal cycles. Parental males establish nests under rocks in the intertidal zone, where they reside until the eggs they guard are fully developed. In contrast, females and sneaker males leave the nests shortly after spawning.

MaTSE: the gene expression time-series explorer.

Background: High throughput gene expression time-course experiments provide a perspective on biological functioning recognized as having huge value for the diagnosis, treatment, and prevention of diseases. There are however significant challenges to properly exploiting this data due to its massive scale and complexity. In particular, existing techniques are found to be ill suited to finding patterns of changing activity over a limited interval of an experiments time frame.

Acute embryonic exposure to nanosilver or silver ion does not disrupt the stress response in zebrafish (Danio rerio) larvae and adults.

The antibacterial properties of silver nanoparticles (AgNPs) are widely exploited in a variety of medical and consumer products. AgNPs in these products can be released into the aquatic environment, however, the potential toxicity of AgNPs to organisms, including fish, is yet to be fully understood. The present study aimed to investigate the effects of the early life exposure to AgNPs on the hypothalamic-pituitary-interrenal (HPI) axis-mediated stress response in zebrafish (Danio rerio) larvae and adults.
