Prebiotics and calcium bioavailability. (2003)

A prebiotic substance has been defined as a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon. Therefore, compared to probiotics, which introduce exogenous bacteria into the colonic microflora, a prebiotic aims at stimulating the growth of one or a limited number of the potentially health-promoting indigenous micro-organisms, thus modulating the composition of the natural ecosystem. In recent years, increasing attention has been focussed on the possible beneficial effects of prebiotics, such as enhanced resistance to invading pathogens, improved bowel function, anti-colon cancer properties, lipid lowering action, improved calcium bioavailability, amongst others. The objective of this review is to critically assess the available data on the effects of prebiotics on calcium bioavailability, and place it in the context of human physiology and, when possible, explain the underlying cellular and molecular mechanisms. The review will also try to highlight future areas of research that may help in the evaluation of prebiotics as potential ingredients for functional foods aimed at enhancing calcium bioavailability and protecting against osteoporosis.
Effects of Sulindac and Ibuprofen in Patients with Chronic Glomerular Disease (1984)

We investigated whether the glomerular synthesis of prostacyclin modulates the renal blood flow and glomerular filtration rate in chronic glomerular disease. The urinary excretion of 6-keto-prostaglandin F1 alpha, a stable breakdown product of prostacyclin, was significantly (P less than 0.01) reduced in 20 women with chronic glomerular disease, as compared with 19 controls, whereas excretion of urinary prostaglandin E2 was unchanged. In 10 patients randomly assigned to one week of treatment with ibuprofen, excretion of urinary 6-keto-prostaglandin F1 alpha and prostaglandin E2 was reduced by 80 per cent, the level of serum creatinine was increased by 40 per cent, and creatinine and para-aminohippurate clearances were reduced by 28 and 35 per cent, respectively. The reduction of both clearances was inversely related (P less than 0.01) to the basal urinary excretion of 6-keto-prostaglandin F1 alpha but not of prostaglandin E2. No functional changes were detected in five healthy women, despite a similar suppression of renal prostacyclin synthesis by ibuprofen. In contrast, one week of treatment with sulindac did not affect renal prostacyclin synthesis or renal function in the other 10 patients, despite a marked inhibition of extrarenal cyclooxygenase activity. We conclude that in patients with mild impairment of renal function, the renal blood flow and glomerular filtration rate are critically dependent on prostacyclin production. In such patients sulindac may be a safe substitute for other nonsteroidal antiinflammatory drugs.
Block Copolymer Micelle Shuttles with Tunable Transfer Temperatures between Ionic Liquids and Aqueous Solutions (2008)

Four poly((1,2-butadiene)- block-ethylene oxide) (PB-PEO) diblock copolymers were shown to self-assemble into micelles with PB cores and PEO coronas (including spheres, cylinders, and vesicles) in the ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]). All four systems exhibited the "micelle shuttle" (He, Y.; Lodge, T. P. J. Am. Chem. Soc. 2006, 128, 12666-12667), whereby PB-PEO micelles transferred, reversibly and with preservation of micelle structure, from an aqueous phase at room temperature to a hydrophobic ionic liquid at high temperature. The micelle size (both mean and distribution) depends on whether it was initially dissolved in water or in the ionic liquid, but the initial micelle structures in the ionic liquid were shown by dynamic light scattering to be preserved during the transfer and persist essentially unchanged for months in both the ionic liquid and water. The transfer was shown to be driven by the deteriorating solvent quality of water for PEO at high temperature, while the ionic liquid remains a good solvent. The transfer temperature could be tuned by adding ionic or nonionic additives to the aqueous phase to change the solvent quality of water for PEO, and by using ionic liquids with different polarity.
Left Ventricular Assist Device–Associated Carbon Monoxide and Iron-Enhanced Hypercoagulation (2015)

Left ventricular assist device (LVAD) therapy is associated with thrombophilia despite anticoagulation. Of interest, LVAD patients have increased carboxyhemoglobin, a measure of upregulated heme oxygenase (Hmox) activity that releases carbon monoxide (CO) and iron. Given that CO and iron enhance plasmatic coagulation, we determined if LVAD patients had hypercoagulability and decreased fibrinolytic vulnerability with measurable CO and iron-mediated effects. Blood samples were obtained a month or more after implantation of the LVAD. Thrombelastographic methods to assess coagulation kinetics, fibrinolytic kinetics, formation of carboxyhemefibrinogen, and iron-mediated enhancement of clot growth were utilized. Coagulation and fibrinolytic parameter normal individual (n = 30) plasma values were determined. Sixteen LVAD patients were studied. CO and iron enhancement of coagulation were observed in the majority of LVAD patients, contributing to hypercoagulation. However, most patients demonstrated abnormally increased rates of clot lysis. Critically, hemolysis as assessed by circulating lactate dehydrogenase activity was small in this cohort, and only four patients without comorbid states (e.g., obesity, diabetes, sleep apnea) were hypercoagulable with evidence of Hmox upregulation. However, seven patients with comorbidities were hypercoagulable with Hmox upregulation. Future investigation of CO and iron-related thrombophilia and comorbid disease is warranted to define its role in LVAD-related thrombosis.

Our ubiquitous multimodal multimedia (MM) computing system selects the appropriate media and modalities based on the user's context and user's profile. This paper demonstrates the design of a fault-tolerant ubiquitous MM computing system. The requirements analysis is undertaken by considering the quality attributes desired by different stakeholders. We use the attribute-driven design method in the requirement analysis and Architecture Tradeoffs Analysis Method in evaluating the system architecture. In this paper we conduct all tests and explain results through stochastic colored Petri Net specification, citing pre- and postcondition of each scenario.
02 - DEVELOPING A BIOPSYCHOSOCIAL PAIN AND OPIOID USE CURRICULUM FOR MEDICAL STUDENTS AT MAYO CLINIC (2019)

Background: There are 100 million people with chronic pain in Europe, but despite the large and increasing burden it has not received sufficient policy attention. To date there has been little research to identify critical areas of need in the policy environment, or what actions are required to support treatment and care for patients.Methods: A systematic literature review across 7 European countries was undertaken to populate a comprehensive framework comparing national government policies and non-governmental initiatives in chronic pain across four policy areas: awareness and recognition, coordination and diagnosis, access to treatment and ongoing support.Results: Chronic pain is not prioritized through coordinated national plans, although targeted policies and programs exist. Patient advocacy groups are key drivers for awareness-related policy change and implementation, however these often receive limited government support. While clinical guidelines on diagnosis, treatment and management have been established, application is often limited, and many countries report delays in diagnosis and suboptimal pain management. There are no provisions in value assessment and reimbursement processes applied to specialized pain treatments, and dedicated centres supporting patientsu2019 long-term care varies across regions and countries.Conclusions: Given the challenges facing patients, sharing best practices is vital. Governments should prioritize chronic pain; developing a clear policy agenda to address the lack of awareness amongst patients, healthcare professionals and payers. Policy should ensure patients play an important role in the assessment of treatments and that there are appropriate provisions in value assessment methodology in order to ensure appropriate access to treatment and care.

The document defines the terms most commonly encountered in the field of polymer reactions and functional polymers. The scope has been limited to terms that are specific to polymer systems. The document is organized into three sections. The first defines the terms relating to reactions of polymers. Names of individual chemical reactions are omitted from the document, even in cases where the reactions are important in the field of polymer reactions. The second section defines the terms relating to polymer reactants and reactive polymeric materials. The third section defines the terms describing functional polymeric materials.
A New Amperometric Biosensor for Diamine: Use of a Conducting Polymer Layer (2013)

Diamine oxidase (DAO) from Porcine kidney E.C. 1.4.3.6 is used for the amperometric detection of biogenic amines. Immobilization of enzyme is performed via entrapment in conducting poly (3,4-ethylenedioxythiophene) during electrochemical polymerization. The responses of the enzyme electrodes are measured via monitoring current at +0.7 V. In order to minimize the common interferences, an over oxidized film of polypyrrole is introduced to the electrode. Thickness of the film, kinetic parameters, substrate specificity, storage stability, pH were investigated. In spite of very low activity of the commercial DAO, the biosensor displayed high response in flow experiments, short response time, a good linear response and low detection limit and excellent anti-interference characteristics.
Neoadjuvant Doxil Chemotherapy Prior to Androgen Ablation Plus Radiotherapy for High-Risk Localized Prostate Cancer (2003)

Patients with clinical T3 or T4 prostate cancer or with elevated serum prostate-specific antigen (PSA) levels greater than 40 ng/ml are at high risk of failure with primary treatment. Chemotherapy administered at the time of diagnosis may decrease the risk of recurrence. Patients with high risk localized prostate cancer were treated with two cycles of liposomal doxorubicin (Doxil) at 50 mg/m2 every 28 days. Patients were assessed for response by digital rectal examination (DRE), PSA, and endorectal magnetic resonance imaging (MRI) (erMRI). Patients were then treated with androgen ablative therapy and prostate radiotherapy. Seven patients were treated. Three patients had T3 disease, and 4 patients had T2b disease with either PSA greater than 40 ng/ml or erMRI evidence of seminal vesicle involvement or extracapsular disease. Median PSA was 29.4 ng/ml. None of the seven patients experienced a significant response, as measured by changes in DRE, PSA, or erMRI. Toxicity was significant, with 4 of 7 patients developing skin toxicity. All seven patients responded to androgen ablative therapy and prostate irradiation. Neoadjuvant liposomal doxorubicin demonstrates no apparent activity and significant toxicity. New strategies are needed to improve outcomes in high-risk prostate cancer.
Genome‐wide profiling of oral squamous cell carcinoma (2004)

Oral squamous cell carcinoma (OSCC) is a common malignancy, the incidence of which is particularly high in some Asian countries due to the geographically linked areca quid (AQ) chewing habit. In this study, array-based comparative genomic hybridization was used to screen microdissected OSCCs for genome-wide alterations. The highest frequencies of gene gain were detected for TP63, Serpine1, FGF4/FGF3, c-Myc and DMD. The highest frequencies of deletion were detected for Caspase8 and MTAP. Gained genes, classified by hierarchical clustering, were mainly on 17q21-tel; 20q; 11q13; 3q27-29 and the X chromosome. Among these, gains of EGFR at 7p, FGF4/FGF3, CCND1 and EMS1 at 11q13, and AIB1 at 20q were significantly associated with lymph node metastasis. The genomic profiles of FHIT and EXT1 in AQ-associated and non-AQ-associated OSCCs exhibited the most prominent differences. RT-PCR confirmed the significant increase of TP63 and Serpine1 mRNA expression in OSCC relative to non-malignant matched tissue. A significant increase in Serpine1 immunoreactivity was observed from non-malignant matched tissue to OSCC. However, there was no correlation between the frequent genomic loss of Caspase 8 and a significant decrease in Caspase8 expression. These data demonstrate that genomic profiling can be useful in analysing pathogenetic events involved in the genesis or progression of OSCC.
Perception of dynamic facial expressions of emotion between dogs and humans (2020)

Facial expressions are a core component of the emotional response of social mammals. In contrast to Darwin's original proposition, expressive facial cues of emotion appear to have evolved to be species-specific. Faces trigger an automatic perceptual process, and so, inter-specific emotion perception is potentially a challenge; since observers should not try to "read" heterospecific facial expressions in the same way that they do conspecific ones. Using dynamic spontaneous facial expression stimuli, we report the first inter-species eye-tracking study on fully unrestrained participants and without pre-experiment training to maintain attention to stimuli, to compare how two different species living in the same ecological niche, humans and dogs, perceive each other's facial expressions of emotion. Humans and dogs showed different gaze distributions when viewing the same facial expressions of either humans or dogs. Humans modulated their gaze depending on the area of interest (AOI) being examined, emotion, and species observed, but dogs modulated their gaze depending on AOI only. We also analysed if the gaze distribution was random across AOIs in both species: in humans, eye movements were not correlated with the diagnostic facial movements occurring in the emotional expression, and in dogs, there was only a partial relationship. This suggests that the scanning of facial expressions is a relatively automatic process. Thus, to read other species' facial emotions successfully, individuals must overcome these automatic perceptual processes and employ learning strategies to appreciate the inter-species emotional repertoire.
Cell Fusion as a Cause of Prostate Cancer Metastases (2011)

Abstract : The main goal of the study funded by this grant was to test a hypothesis that cell fusion between tumor cells, or between tumor and normal cells, contributes to metastasis. This hypothesis suggests that cell fusion contributes to carcinogenesis through two mechanisms: by generating cells with diverse genetic and epigenetic properties and by providing tumor cells with qualities of normal cells that are required to travel throughout the body while remaining alive. This hypothesis can explain why tumor cells can grow at distant sites, why they express proteins that are normally expressed by cells of the metastasized tissue, and why only a minute fraction of cells released by primary tumors form metastases. The proposed research was designed to explain gene transfer between two lines of human prostate cancer cells PC3 in vivo and to determine whether this gene transfer is mediated by cell fusion and whether cell fusion affects metastatic potential of these cells. We found that gene transfer was mediated by a xenotropic mouse virus and developed approaches to generate cell hybrids for testing their metastic potential.
Four-dimensional x-ray phase tomography with Talbot interferometer and white synchrotron light (2010)

Taking advantage of the fact that an X-ray Talbot interferometer functions with X-rays of a broad energy bandwidth, high-speed X-ray phase tomography has been demonstrated by using white synchrotron light. Time resolution in addition to three-dimensional spatial resolution has been attained, and we report this achievement as the first four-dimensional (4D) X-ray phase tomography. Moire image movies of samples rotating at a speed of 1 or 2 rps generated by a Talbot interferometer were recorded at a frame rate of up to 1 kf/s, and differential phase image movies of the same frame rate were created by the Fourier-transform method. Consequently, a sub-second time resolution was achieved in the 4D phase tomography, while the spatial resolution was below 0.1 mm and 0.05 mm in axial and in-plane directions, respectively. An X-ray Talbot interferometer generates visibility images in addition to differential phase images, showing the distribution of microstructures, which cause ultra-small angle scattering but cannot be resolved individually with system spatial resolution. Tomographic image reconstruction from the visibility images was also demonstrated.
A Review of Molecular Contrasts Between Arresting and Viable Porcine Attachment Sites (2007)

Significant spontaneous fetal loss of unknown cause occurs in North American commercial swine. About 30% of conceptuses, thought to be genetically normal, are lost during the peri-attachment period. An additional 20% are lost at mid-pregnancy. Littermate endometrial and trophoblast biopsies were studied by quantitative real-time PCR for gene expression, and immunohistochemistry for protein expression at gestation day (gd)15-23 and 50. RNA analyses were also conducted on endometrial lymphocytes and arterial endothelial cells removed from biopsies by laser capture microdissection. Genes were selected for study from human literature and cloned as required. As in humans, angiogenic, cytokine, chemokine and chemokine decoy receptor gene expression occurs at the porcine maternal-fetal interface. In each tissue studied, distinct patterns of expression are found between early and mid-pregnancy, as well as between viable and arresting conceptus attachment sites. These changes involve both endometrial lymphocytes and dendritic cells. Restriction in endometrial angiogenesis, reduction in expression of the chemokine decoy receptor D6, and reduction in dendritic cell numbers contribute to fetal arrest. In peri-attachment loss, interferon-gamma is more abundantly transcribed than tumor necrosis factor-alpha, but this ratio is reversed during midgestation failure. Further characterization of spontaneous fetal loss in pigs will identify targets for modification by hog producers and may provide a model for identification of antecedents to fetal loss in humans.

Probing Pineal‐specific Gene Expression with Transgenic Zebrafish† (2008)

The pineal gland of zebrafish (Danio rerio) contains light-sensitive photoreceptor cells and plays an important role in the neuroendocrine system. The zebrafish exorhodopsin gene encodes a pineal-specific photoreceptive protein, whose promoter region harbors a cis-acting element, pineal expression-promoting element (PIPE), directing pineal-specific gene expression. For in vivo genetic studies on PIPE-binding proteins and their regulatory mechanisms, we generated a transgenic zebrafish line, Tg(P(20)-rh/P:gfp), that expresses green fluorescent protein (GFP) under the control of the zebrafish rhodopsin promoter fused with 20 PIPE repeats. In Tg(P(20)-rh/P:gfp) fish, PIPE-dependent gene expression is visualized by GFP fluorescence in the pineal gland along with PIPE-independent GFP signals in the retinal rod photoreceptors. The transgenic fish exhibit detectable and reproducible GFP fluorescence in the larval pineal gland by 5 days postfertilization. Antisense morpholino-mediated knock-down of a pineal transcription factor gene, otx5, suppresses pineal GFP expression in the transgenic line. In a pilot screen of N-ethyl-N-nitrosourea-treated fish of the GFP transgenic line, we isolated potential dominant mutations that cause attenuation of pineal GFP fluorescence with a marginal effect on the retinal GFP signal. The results suggest that the Tg(P(20)-rh/P:gfp) line will be useful for detecting deficits in PIPE-dependent gene expression in the pineal gland.
Computational Intelligence for the Smart Grid-History, Challenges, and Opportunities (2011)

This paper reviews the evolution of four generations of concepts of the “smart grid,” the role of computational intelligence in meeting their needs, and key examples of relevant research and tools. The first generation focused on traditional concepts like building more wires, automated meters, workforce development, and reducing blackouts, but it already had many uses for computational intelligence. The second generation, promulgated by Massoud Amin at EPRI, entailed greater use of global control systems and stability concepts, and coincided with new issues of market design and time of day pricing. New third generation and fourth generation concepts aim for a truly intelligent power grid, addressing new requirements for a sustainable global energy system, making full use of new methods for optimization across time, pluggable electric vehicles, renewable energy, storage, distributed intelligence and new neural networks for handling complexity and stochastic challenges. Important opportunities for society and new fundamental research challenges exist throughout.
