BACKGROUND: Vector-borne diseases of dogs in Australian Aboriginal communities are relatively unexplored. These dogs represent a unique group with variable ecto- and endo-parasitic burdens, nutritional stresses and a general lack of veterinary intervention. We investigated haemoprotozoal and bacterial pathogen prevalences in relation to erythrocyte and platelet numbers in dogs from North-West New South Wales (N-W NSW) and the Northern Territory (NT; Central Australia). METHODS: Real-time PCR (qPCR) amplification of Anaplasma platys, Babesia vogeli, Mycoplasma haemocanis, Candidatus Mycoplasma haematoparvum and Bartonella spp...

A general and facile methodology for temperature-dependent enantiodivergent and diastereodivergent synthesis of amino acids with one or multiple chiral centers was developed. Camphor-based tricyclic iminolactones attack electrophiles from the endo face at low temperature (-78 to -40 °C) and from the exo face at high temperature (-10 to 25 °C).

Prediction of follow-up shock is crucial to stratify patients with dilated cardiomyopathy (DCM) requiring implantable cardioverter defibrillator (ICD). The objective of the article is to assess the predictive value of endo-myocardial biopsy (EMB) towards ICD shock and follow-up mortality. A series of patients with DCM scheduled for ICD implantation underwent EMB to further determine the genesis of DCM. Presence of fibrosis and inflammation was documented and related to outcomes. A total of 240 patients were referred for ICD as primary (56%) and secondary (44%) prophylaxis...

The free-living ciliates of the order Metopida Jankowski, 1980 are pivotal players in the microbial food web of the sulfuretum, acting as hosts to prokaryotic endo- and ectosymbionts. They are also of interest in the study of the function and evolution of their mitochondrion-related organelle, the hydrogenosome. The taxonomy and phylogeny of this group remains confused, due, in large part, to the fact that most of its taxa have not been characterized by modern methods including molecular sequencing. In this report we provide morphologic and molecular characterization of seven taxa from the poorly-known resurrected genus Urostomides obtained in the course of broad geographic sampling...

Inefficient intracellular gene delivery is still a limitation for the clinical translation of gene therapy. Recently, photochemical internalization (PCI) has emerged with the opportunity to overcome endo-lysosomal sequestration in gene delivery, which utilizes photosensitizer (PS) plus light generating reactive oxygen species (ROS) at sub-lethal level to facilitate intracellularly targeted drug delivery. In this work, asymmetric polyplex-nanocapsules were prepared based on the triblock copolymers of PEG-PCL-PEI by using the simple solvent-injection method...

Targeted microbubbles has the potential to be used for ultrasound (US) therapy and diagnosis of various cancers. In the present study, US was irradiated to oral squamous cell carcinoma cells (HSC-2) in the presence of cetuximab coated albumin microbubbles (CCAM). Cell killing rate with ultrasound treatment at 0.9W/cm(2) and 1.0W/cm(2) in the presence of CCAM was greater compared to non-targeted albumin microbubbles (p < 0.05). On the other hand, selective cell killing was not observed in human myelomonocytic lymphoma cell line (U937) that had no affinity to cetuximab...

BACKGROUND: Multiple dissections rarely occur with ruptured vertebral artery dissecting aneurysms (VADAs). Here, we report three cases of ruptured VADA concurrent with spontaneous cervical internal carotid artery (ICA) dissection. CASE DESCRIPTION: None of the three patients had a history of vasculopathy or trauma. All ruptured VADAs were treated with internal coil trapping in the acute stage of subarachnoid hemorrhage (SAH). Rebleeding was not observed in any patients after the treatment...

BACKGROUND: Two-dimensional (2D) speckle tracking imaging (STI) is a non-invasive method used to assess subtle changes in left ventricular (LV) function such as strain and rotational dynamics. However, 2D methodology is complicated by issues such as the out-of-plane problem inherent in short-axis imaging. In addition, circumferential rotation contributes to three-dimensional (3D) wall deformations and affects tracking accuracy. By using 3D-STI technique, we evaluated LV global longitudinal strain (GLS) and apical rotation in severe aortic stenosis (AS) patients with preserved LV ejection fraction (EF)...

Endo-polygalacturonases (PGs) and xylanases have been shown to play an important role during pathogenesis of some fungal pathogens of dicot plants, whilst their role in monocot pathogens is less defined. Pg1 and xyr1 genes of the wheat pathogen Fusarium graminearum encode the main PG and the major regulator of xylanase production, respectively. Single and double disrupted mutants for these genes were obtained to assess their contribution to fungal infection. Compared to wild-type strain, the ∆pg mutant showed a nearly abolished PG activity, slight reduced virulence on soybean seedlings but no significant difference in disease symptoms on wheat spikes; the ∆xyr mutant was strongly reduced in xylanase activity and moderately reduced in cellulase activity but was as virulent as wild-type on both soybean and wheat plants...

We constructed a model using a support vector machine to determine whether an inpatient will suffer a fall on a given day, depending on patient status on the previous day. Using fall report data from our own facility and intensity-of-nursing-care-needs data accumulated through hospital information systems, a dataset comprising approximately 1.2 million patient-days was created. Approximately 50% of the dataset was used as training and testing data. A multistep grid search was conducted using the semicomprehensive combination of three parameters...

The threading of mono-stoppered alkylbenzylammonium axles 7+ and 8+ with the calix[6]-wheel 3 can occurs by both the routes of entering of the macrocycle 3 in the cone conformation: through-the-exo-rim and the through-the-endo-rim passage. Thus, under thermodynamic conditions, with both the axles 7+ and 8+ the two possible oriented calix[2]pseudorotaxane, namely endo-benzyl and endo-alkyl, are formed with a stereoselectivity controlled by endo-alkyl rule. Interestingly, by 1H NMR monitoring of the threading process between 8+ and 3, we revealed two calix[2]pseudorotaxane isomers in which the calix-weel adopts a 1,2,3-alternate and cone conformations, respectively, the kinetic and thermodynamic species...

The thermal dependence of salinity-gradient-driven energy conversion by reverse electrodialysis using a mesoporous silica thin film with pores ca. 2-3 nm in diameter was studied in a temperature range of 293-333 K. As the temperature increases, the surface charge density of mesopores increases owing to an increase in the zeta potential of the pore walls, which in turn increases the concentration of counter-ions in the electrical double layer. The ion mobility also increases with increasing temperature owing to a decrease in the liquid viscosity...

The plant-based-sea water culture medium is introduced to in vitro cultivation and in situ recovery of the microbiome of halophytes. The ice plant (Mesembryanthemum crystallinum) was used, in the form of juice and/or dehydrated plant powder packed in teabags, to supplement the natural sea water. The resulting culture medium enjoys the combinations of plant materials as rich source of nutrients and sea water exercising the required salt stress. As such without any supplements, the culture medium was sufficient and efficient to support very good in vitro growth of halotolerant bacteria...

In neurodegenerative diseases, seeding is a process initiated by the internalization of exogenous protein aggregates. Multiple pathways for internalization of aggregates have been proposed, including direct membrane penetration and endocytosis. To decipher the seeding mechanisms of alpha-synuclein (αS) aggregates in human cells, we visualized αS aggregation, endo-lysosome distribution, and endo-lysosome rupture in real-time. Our data suggest that exogenous αS can seed endogenous cytoplasmic αS by either directly penetrating the plasma membrane or via endocytosis-mediated endo-lysosome rupture, leading to formation of endo-lysosome-free or endo-lysosome-associated αS aggregates, respectively...

In this study, a fast and easy-to-use capillary-type microdevice for competitive bioassay is proposed. The device is composed of polydimethylsiloxane (PDMS) microchannel arrays that separately immobilize polyethylene glycol (PEG) coating, which contained graphene oxide (GO)-analyte conjugates and fluorescently-labelled receptor proteins. The working principle of the device involved the spontaneous dissolution of the PEG coating, subsequent mixing and reaction with analyte to give fluorescence response, triggered by the capillary action-mediated introduction of a sample solution...

BACKGROUND: Chronic alcohol abuse, a major risk factor for such diseases as hepatitis and cirrhosis, impairs hepatic alcohol dehydrogenase (ADH, key ethanol metabolizing enzyme). Therefore, differentially altered hepatic and plasma proteomes were identified in chronic ethanol feeding model of hepatic ADH-deficient (ADH(-) ) deer mice to understand the metabolic basis of alcoholic liver disease (ALD). METHODS: ADH(-) deer mice were fed 3.5g% ethanol via Lieber-DeCarli liquid diet daily for three months, and histology of the liver assessed...

We disclosed the unique discrimination property of Endo IV toward stable single-base mismatches located at the second nucleotide 3' to the AP site. Coupled with thermodynamic differentiation and competitive blocker strands, a highly sensitive and specific detection system was established with discrimination factors of 510-1079 for G:X mismatches and LODs of 0.003-0.005% for KRAS G12A, KRAS G12V and KRAS G12S mutations.
