To gain a better understanding of cold acclimation in rhododendron and in woody perennials in general, we used the 2D-DIGE technique to analyze the rhododendron proteome during the seasonal development of freezing tolerance. We selected two species varying in their cold acclimation ability as well as their thermonasty response (folding of leaves in response to low temperature). Proteins were extracted from leaves of non-acclimated (NA) and cold acclimated (CA) plants of the hardier thermonastic species, R. catawbiense (Cata...

Parkinson's disease (PD) is a progressive neurodegenerative disease that affects ∼5 million people around the world. PD etiopathogenesis is poorly understood and curative or disease modifying treatments are not available. Mechanistic studies have identified numerous pathogenic pathways that overlap with many other neurodegenerative diseases. Mutations in the protein optineurin (OPTN) have recently been identified as causative factors for glaucoma and amyotrophic lateral sclerosis. OPTN has multiple recognized roles in neurons, notably in mediating autophagic flux, which has been found to be disrupted in most neurodegenerative diseases...

Ants are known to be capable of homing to their nest after displacement to a novel location. This is widely assumed to involve some form of retinotopic matching between their current view and previously experienced views. One simple algorithm proposed to explain this behavior is continuous retinotopic alignment, in which the ant constantly adjusts its heading by rotating to minimize the pixel-wise difference of its current view from all views stored while facing the nest. However, ants with large prey items will often drag them home while facing backwards...

BACKGROUND: Choosing Wisely Canada is a campaign that fosters conversations between physicians and patients about high-value health care. However, little is known about physicians' readiness to have these conversations. Our objective was to determine how ready practising internists were to embrace and openly address high-value care during conversations with patients or their families. METHODS: Practising internists in hospitals affiliated with McMaster University, Hamilton, Ontario, were invited to complete an electronic survey with 3 clinical scenarios: each had 3 low-value interventions that had been requested by the patient or family member...

BACKGROUND: Individuals who adhere to reduced-sodium diets come to prefer less salt over time, but it is unclear whether sweet taste perception is modulated by reduced sugar intake. OBJECTIVE: The objective was to determine how a substantial reduction in dietary intake of simple sugars affects sweetness intensity and pleasantness of sweet foods and beverages. DESIGN: Healthy men and women aged 21-54 y participated for 5 mo. After the baseline month, 2 subject groups were matched for demographic characteristics, body mass index, and intake of simple sugars...

BACKGROUND: Patients' comments about doctors are increasingly available on the internet. The effects of these anecdotal accounts on consumers' engagement with reports on doctor quality, use of more statistically reliable performance measures, and ability to choose doctors wisely are unknown. OBJECTIVE: To examine the effects of providing patient comments along with standardized performance information in a web-based public report. DESIGN: Participants were randomly assigned to view 1 of 6 versions of a website presenting comparative performance information on fictitious primary care doctors...

Academic medical centers (AMCs)--which include teaching hospital(s) and additional care delivery entities--that form accountable care organizations (ACOs) must decide whether to partner with other provider entities, such as community practices. Indeed, 67% (33/49) of AMC ACOs through the Medicare Shared Savings Program through 2014 are believed to include an outside community practice. There are opportunities for both the AMC and the community partners in pursuing such relationships, including possible alignment around shared goals and adding ACO beneficiaries...

PURPOSE: The objective of this study is to develop an algorithm that accurately reconstructs a representative 4D-MRI from a multi-slice dynamic 2D-MRI scan. METHODS: Multi-slice dynamic 2D-MR images at sagittal view are acquired using a cyclic and interleaved protocol to avoid crosstalk between adjacent slices and capture temporal anatomical variations. We chose sagittal view as it captures both superior-inferior and anterior-posterior directions where the most dominant respiration-induced anatomical motion happens...

BACKGROUND: Lighthouse Trust operates two public HIV testing, treatment and care clinics in Lilongwe, Malawi, caring for over 26 000 people living with HIV, 23 000 of whom are on antiretroviral treatment (ART). In August 2010, Lighthouse Trust piloted a step-wise integration of sexual and reproductive health (SRH) services into routine HIV care at its Lighthouse clinic site. The objectives were to increase uptake of family planning (FP), promote long-term reversible contraceptive methods, and increase access, screening and treatment for cervical cancer using visual inspection with acetic acid...

The rapid rise in morbidity and mortality from drug-resistant pathogenic bacteria has generated elevated interest in combination therapy using antimicrobial agents. Antimicrobial peptides (AMPs) are a candidate drug class to advance the development of combination therapies. Although the literature is ambiguous, the generic membrane disrupting activity of AMPs could enable them to synergize with conventional small molecule antibiotics by increasing access to the cell and by triggering membrane damage mediators...

PURPOSE: To investigate atlas-based auto-segmentation methods to improve the quality of the delineation of low-risk clinical target volumes (CTVs) of unilateral tonsil cancers. METHOD AND MATERIALS: Sixteen patients received intensity modulated radiation therapy for left tonsil tumors. These patients were treated by a total of 8 oncologists, who delineated all contours manually on the planning CT image. We chose 6 of the patients as atlas cases and used atlas-based auto-segmentation to map each the atlas CTV to the other 10 patients (test patients)...

BACKGROUND: Structure and function of the human brain are subjected to dramatic changes during its development and aging. Studies have demonstrated that microRNAs (miRNAs) play an important role in the regulation of brain development and have a significant impact on brain aging and neurodegeneration. However, the underlining molecular mechanisms are not well understood. In general, development and aging are conventionally studied separately, which may not completely address the physiological mechanism over the entire lifespan...

The effects of caffeine are mediated through its non-selective antagonistic effects on adenosine A(1) and A(2A) adenosine receptors resulting in increased neuronal activity but also vasoconstriction in the brain. Caffeine, therefore, can modify BOLD FMRI signal responses through both its neural and its vascular effects depending on receptor distributions in different brain regions. In this study we aim to distinguish neural and vascular influences of a single dose of caffeine in measurements of task-related brain activity using simultaneous EEG-FMRI...

Molecular techniques that assess biodiversity through the analysis of a small segment of mitochondrial genome have been getting wide attention for inferring the mammalian diversity. Due to their highly conserved nature, specific mitochondrial genes offer a promising tool for phylogenetic analysis. However, there is no established criteria for selecting the typical mitochondrial DNA (mtDNA) segments to achieve a greater resolving power. We therefore chose the family Bovidae as a model and compared the tree-topologies resulting from the commonly used and phylogenetically-informative genes including 16S rRNA, 12S rRNA, COI, Cyt b and D-loop with respect to complete mitochondrial genome...

BACKGROUND: There is a paucity of literature comparing Bayesian analytic techniques with traditional approaches for analyzing clinical trials using real trial data. METHODS: We compared Bayesian and frequentist group sequential methods using data from two published clinical trials. We chose two widely accepted frequentist rules, O'Brien-Fleming and Lan-DeMets, and conjugate Bayesian priors. Using the nonparametric bootstrap, we estimated a sampling distribution of stopping times for each method...
