INTRODUCTION: The Rhesus monkey (RM) is an excellent preclinical model in kidney, heart and islet transplantation that has provided the basis for new immunosuppressive protocols for clinical studies. However, there remain relatively few liver transplantation (LT) models in nonhuman primates. In this study, we analyzed the immune cell populations of PBMCs and secondary lymphoid organs along with livers of normal rhesus monkeys and compared them to those of rejecting liver transplanted recipient's following withdrawal of immunosuppression...

The Cohen-Mansfield Agitation Inventory was a tool originally developed for use in research to measure agitation and subsequently used in clinical settings. It was the primary outcome measure for a randomised controlled trial which evaluated the effects and feasibility of a physiotherapist-led physical exercise intervention on agitation and physical performance of individuals living with dementia in nursing homes. The study produced weak results in regards to the Cohen-Mansfield Agitation Inventory due to small sample size and perceived issues with the use of the Cohen-Mansfield Agitation Inventory...

OBJECTIVES: The side population (SP) contains cells with stem cell/progenitor properties. Previously, we observed that the mouse pancreas SP expanded after pancreatic injury. We aimed to characterize the SP in human pancreas as a potential source of stem cells. METHODS: Human organ donor pancreata were fractionated into islets and exocrine tissue, enriched by tissue culture and dispersed into single cells. Cells were phenotyped by flow cytometry, and the SP was defined by efflux of fluorescent dye Hoechst 33342 visualized by ultraviolet excitation...

Cardiac arrhythmias are major life-threatening conditions. The landmark discovery of induced pluripotent stem cells has provided a promising in vitro system for modeling hereditary cardiac arrhythmias as well as drug development and toxicity testing. Nowadays, nutraceuticals are frequently used as supplements for cardiovascular therapy. Here we studied the cardiac effects of hawthorn (Crataegus pentagyna) leaf extract using cardiomyocytes (CMs) differentiated from healthy human embryonic stem cells, long QT syndrome type 2 (LQTS2), and catecholaminergic polymorphic ventricular tachycardia type 1 (CPVT1) patient-specific induced pluripotent stem cells...

Phytochemical investigation on the seeds of hawthorn (Crataegus spp.) led to the isolation of a new compound, (7'R, 8'R, 8S)-isolariciresinol (1), along with six known compounds (2-7). The structures of all compounds were determined based on spectroscopic data interpretation. The Aβ1-42 inhibition activity of all isolated compounds was evaluated in vitro. As a result, compounds 5 and 6 showed stronger inhibition of Aβ1-42 aggregation than curcumin, with inhibition rates of 70.59 and 68.14% at 20 μM. The possible mechanism of interaction between Aβ1-42 and the active compounds 5 and 6 was also investigated by molecular docking...

In this paper, we propose a new type of rotational Doppler shift measurement based on the OAM of light which is capable of measuring the rotation of a point source in the plane orthogonal to the observer line of sight. By analysing the correlations between OAM states of light emitted by rotating sources, the rotational Doppler shift, and hence the rate of rotation, can be measured. We demonstrate that an OAM interferometer capable of extracting the rotational Doppler shift from OAM correlations can be constructed from a standard OAM modesorter combined with a phase filter...

The apple maggot fly, Rhagoletis pomonella Walsh (Diptera: Tephritidae), is a serious quarantine pest in the apple-growing regions of central Washington and Oregon. The fly is believed to have been introduced into the Pacific Northwest via the transport of larval-infested apples near Portland, Oregon, within the last 40 yr. However, R. pomonella also attacks native black hawthorn, Crataegus douglasii Lindley (Rosales: Rosaceae), and introduced ornamental hawthorn, Crataegus monogyna Jacquin, in the region. It is, therefore, possible that R...

Rhagoletis zephyria Snow and Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) are morphologically similar flies that attack white-colored snowberry fruit (Symphoricarpos spp.) and yellow/red or dark-colored apple/hawthorn fruit (Malus/Crataegus spp.), respectively. The two flies are caught together on traps in R. pomonella surveys in the western United States, increasing labor needed to process catches. Comparing responses of the two species with different traps could help identify best practices for reducing R...
