    Krp1, also called sarcosin, is a cardiac and skeletal muscle kelch repeat protein hypothesized to promote the assembly of myofibrils, the contractile organelles of striated muscles, through interaction with N-RAP and actin. To elucidate its role, endogenous Krp1 was studied in primary embryonic mouse cardiomyocytes. While immunofluorescence showed punctate Krp1 distribution throughout the cell, detergent extraction revealed a significant pool of Krp1 associated with cytoskeletal elements. Reduction of Krp1 expression with siRNA resulted in specific inhibition of myofibril accumulation with no effect on cell spreading. Immunostaining analysis and electron microscopy revealed that cardiomyocytes lacking Krp1 contained sarcomeric proteins with longitudinal periodicities similar to mature myofibrils, but fibrils remained thin and separated. These thin myofibrils were degraded by a scission mechanism distinct from the myofibril disassembly pathway observed during cell division in the developing heart. The data are consistent with a model in which Krp1 promotes lateral fusion of adjacent thin fibrils into mature, wide myofibrils and contribute insight into mechanisms of myofibrillogenesis and disassembly.

    Kip-related proteins (KRPs) play a major role in the regulation of the plant cell cycle. We report the identification of five putative rice (Oryza sativa) proteins that share characteristic motifs with previously described plant KRPs. To investigate the function of KRPs in rice development, we generated transgenic plants overexpressing the Orysa;KRP1 gene. Phenotypic analysis revealed that overexpressed KRP1 reduced cell production during leaf development. The reduced cell production in the leaf meristem was partly compensated by an increased cell size, demonstrating the existence of a compensatory mechanism in monocot species by which growth rate is less reduced than cell production, through cell expansion. Furthermore, Orysa;KRP1 overexpression dramatically reduced seed filling. Sectioning through the overexpressed KRP1 seeds showed that KRP overproduction disturbed the production of endosperm cells. The decrease in the number of fully formed seeds was accompanied by a drop in the endoreduplication of endosperm cells, pointing toward a role of KRP1 in connecting endocycle with endosperm development. Also, spatial and temporal transcript detection in developing seeds suggests that Orysa;KRP1 plays an important role in the exit from the mitotic cell cycle during rice grain formation.

    The suppression of sprout growth is critical for the long-term storage of potato tubers. 1,4-Dimethylenapthlene (DMN) is a new class of sprout control agent but the metabolic mode of action for this compound has yet to be elucidated. Changes in transcriptional profiles of meristems isolated from potato tubers treated with the DMN were investigated using an Agilent 44 K 60-mer-oligo microarray. RNA was isolated from nondormant Russet Burbank meristems isolated from tubers treated with DMN for 3 days or activated charcoal as a control. RNA was used to develop probes that were hybridized against a microarray developed by the Potato Oligo Chip Initiative. Analysis of the array data was conducted in two stages: total array data was examined using a linear model and the software Limma and pathway analysis was conducted by linking the potato sequences to the Arabidopsis thaliana. DMN elicited a change in a number of transcripts associated with cold responses, water regulation, salt stress, and osmotic adjustment. DMN also resulted in a repression of cyclin or cyclin-like transcripts. DMN also resulted in a 50% decrease in thymidine incorporation suggesting a repression of the S phase of the cell cycle. Quantitative real-time polymerase chain reaction analysis demonstrated that DMN increased transcripts for the cell cycle inhibitors KRP1 and KRP2. We conclude the DMN results in alteration of genes associated with the maintenance of a G1/S phase block possibly through the induction of the cell cycle inhibitors KRP1 and KRP2.

    Single crystals of sarcosine phosphite (SarcH3PO3) have been grown. The amino acid sarcosine is an isomer of the protein amino acid alanine. Both amino acids are described by the same chemical formula but have different structures; or, more specifically, in contrast to the alanine molecule, the sarcosine molecule has a symmetric structure. It has been found that the sarcosine phosphite compound undergoes a structural phase transition at a temperature of approximately 200 K. This result has demonstrated that compounds of achiral amino acids are more susceptible to structural phase transitions.

    The title compound, C(10)H(6)O(8)·2C(3)H(7)NO(2), crystallizes as an adduct with the acid and amino acid mol-ecules in their neutral forms. The asymmetric unit contains one half of a centrosymmetric pyromellitic acid mol-ecule and one sarcosine mol-ecule. The sarcosine has the amine group protonated and the carboxyl group deprotonated, as is usual for amino acids (zwitterionic form). The pyromellitic acid mol-ecules retain the four carboxyl H atoms with the carboxyl groups rotated out of the ring plane [O-C-C-C torsion angles = 24.1 (3) and 61.6 (2)°]. There is a three-dimensional hydrogen-bond network linking the mol-ecules.

The irregular eight-coordinated K(+) polyhedra are connected into infinite chains along [001] via sarcosine molecules. This compound is the first sarcosine metal halogenide salt with a 4:1 ratio. A short overview of other sarcosine metal halogenide salts is presented and relationships to similar glycine salts are discussed.

    Since sarcosine and D,L-alanine co-elute on reversed-phase high-performance liquid chromatography (HPLC) columns and the tandem mass spectrometer cannot differentiate them due to equivalent parent and fragment ions, derivatization is often required for analysis of sarcosine in LC/MS systems. This study offers an alternative to derivatization by employing partial elimination of sarcosine by enzymatic oxidation. The decrease in apparent concentration from the traditionally merged sarcosine-alanine peak associated with the enzymatic elimination has been shown to be proportional to the total sarcosine present (R(2) = 0.9999), allowing for determinations of urinary sarcosine. Sarcosine oxidase was shown to eliminate only sarcosine in the presence of D,L-alanine, and was consequently used as the selective enzyme. This newly developed technique has a method detection limit of 1 μg/L (parts per billion) with a linear range of 3 ppb-1 mg/L (parts per million) in urine matrices. The method was further validated through spiked recoveries of real urine samples, as well as the analysis of 35 real urine samples. The average recoveries for low, middle, and high sarcosine concentration spikes were 111.7, 90.8, and 90.1 %, respectively. In conclusion, this simple enzymatic approach coupled with HPLC/MS/MS is able to resolve sarcosine from D,L-alanine leading to underivatized quantification of sarcosine.

  9. The glycine transport inhibitor sarcosine is an NMDA receptor co-agonist that differs from glycine

    Sarcosine is an amino acid involved in one-carbon metabolism and a promising therapy for schizophrenia because it enhances NMDA receptor (NMDAR) function by inhibiting glycine uptake. The structural similarity between sarcosine and glycine led us to hypothesize that sarcosine is also an agonist like glycine. We examined this possibility using whole-cell recordings from cultured embryonic mouse hippocampal neurons. We found that sarcosine is an NMDAR co-agonist at the glycine binding site. However, sarcosine differed from glycine because less NMDAR desensitization occurred with sarcosine than with glycine as the co-agonist. This finding led us to examine whether the physiological effects of NMDAR activation with these two co-agonists are the same. The difference in desensitization probably accounts for rises in intracellular Ca2+, as assessed by the fluorescent indicator fura-FF, being larger when NMDAR activation occurred with sarcosine than with glycine. In addition, Ca2+-activated K+ currents following NMDAR activation were larger with sarcosine than with glycine. Compared to glycine, NMDAR-mediated autaptic currents decayed faster with sarcosine suggesting that NMDAR deactivation also differs with these two co-agonists. Despite these differences, NMDAR-dependent neuronal death as assessed by propidium iodide was similar with both co-agonists. The same was true for neuronal bursting. Thus, sarcosine may enhance NMDAR function by more than one mechanism and may have different effects from other NMDAR co-agonists. PMID:19433577

  13. Interactions of aminomethylphosphonic acid and sarcosine with montmorillonite interlayer surfaces

    Rennig, Amanda; Slutter, Annette; Tribe, Lorena

    The smectite clay, montmorillonite, can be found in many soils throughout the world. In addition to its importance in agriculture and soil remediation, montmorillonite has extensive applications in industry both in its natural form and as a component of composite materials. The adsorptive properties of montmorillonite have been explored in relation to its interactions with the common herbicide glyphosate. This herbicide, when exposed to microorganisms in the soil is degraded, forming two products: aminomethylphosphonic acid (AMPA) and sarcosine. The atomic-level interactions of these compounds with the montmorillonite interlayer surfaces are studied here using molecular mechanics. The final outcomes of these calculations are analyzed in terms of the proximity of the montmorillonite surface to the moieties of the degradation products. The phosphonate moiety was found to be the most important source of interactions for AMPA, while for sarcosine there was an even distribution between the amino and carboxylic moieties, and Na+ ion mediated surface complexes.0

    In the system sarcosine + L-tartaric acid + H2O we identified several new phases in addition to the previously known species sarcosinium hydrogen L-tartrate (I). Two of them (phases (II) and (III)) were obtained in the form of single crystals. Their crystal and molecular structures were determined. Both phases (II) and (III) have 2:1 composition and contain a zwitter-ionic sarcosine, a sarcosinium cation, and a hydrogen L-tartrate anion in the asymmetric unit and crystallize in the orthorhombic system (space group P212121). In the structure of (II), the sarcosinium cation forms a strong Osbnd H⋯O hydrogen bond (O⋯O distance equals 2.4553(15) Å) with the carboxylate group of the hydrogen L-tartrate anion, while the carboxyl group of the hydrogen L-tartrate anion forms an Osbnd H⋯O hydrogen bond (O⋯O distance equals 2.5065(14) Å) with the carboxylate group of sarcosine zwitter-ion. In the structure of (III) there are dimeric sarcosine sarcosinium cations with an O⋯O distance equal to 2.512(3) Å, while the hydrogen L-tartrate anions form hydrogen bonded usual infinite chains with O⋯O distances equal to 2.510(2) Å between carboxyl and carboxylate groups. Vibrational spectra (infrared and Raman) of (I), (II), (III) are shown and discussed on the basis of their structures. In addition, one more phase (IV) was identified by its infrared spectrum without structure determination.

  15. The Glycine Transport Inhibitor Sarcosine Is an Inhibitory Glycine Receptor Agonist

    2009-01-01

    Summary Sarcosine is an endogenous amino acid that is a competitive inhibitor of the type I glycine transporter (GlyT1), an N-methyl-D-aspartate receptor (NMDAR) co-agonist, and an important intermediate in one-carbon metabolism. Its therapeutic potential for schizophrenia further underscores its clinical importance. The structural similarity between sarcosine and glycine and sarcosine's ability to serve as an NMDAR co-agonist led us to examine whether sarcosine is also an agonist at the inhibitory glycine receptor (GlyR). We examined this possibility using whole-cell recordings from cultured embryonic mouse hippocampal neurons and found that sarcosine evoked a dose-dependent, strychnine sensitive, Cl- current that cross-inhibited glycine currents. Sarcosine evoked this current with Li+ in the extracellular solution to block GlyT1, in neurons treated with the essentially irreversible GlyT1 inhibitor N[3-(4′-fluorophenyl)-3-(4′-phenylphenoxy)propyl]sarcosine (NFPS), and in neurons plated in the absence of glia. These results indicate that the sarcosine currents did not result from GlyT1 inhibition or heteroexchange. We conclude that sarcosine is a GlyR agonist. PMID:19619564

    The glutamatergic system is a key point in pathogenesis of schizophrenia. Sarcosine (N-methylglycine) is an exogenous amino acid that acts as a glycine transporter inhibitor. It modulates glutamatergic transmission by increasing glycine concentration around NMDA (N-methyl-d-aspartate) receptors. In patients with schizophrenia, the function of the glutamatergic system in the prefrontal cortex is impaired, which may promote negative and cognitive symptoms. Proton nuclear magnetic resonance (1H-NMR) spectroscopy is a non-invasive imaging method enabling the evaluation of brain metabolite concentration, which can be applied to assess pharmacologically induced changes. The aim of the study was to evaluate the influence of a six-month course of sarcosine therapy on the concentration of metabolites (NAA, N-acetylaspartate; Glx, complex of glutamate, glutamine and γ-aminobutyric acid (GABA); mI, myo-inositol; Cr, creatine; Cho, choline) in the left dorso-lateral prefrontal cortex (DLPFC) in patients with stable schizophrenia. Fifty patients with schizophrenia, treated with constant antipsychotics doses, in stable clinical condition were randomly assigned to administration of sarcosine (25 patients) or placebo (25 patients) for six months. Metabolite concentrations in DLPFC were assessed with 1.5 Tesla 1H-NMR spectroscopy. Clinical symptoms were evaluated with the Positive and Negative Syndrome Scale (PANSS). The first spectroscopy revealed no differences in metabolite concentrations between groups. After six months, NAA/Cho, mI/Cr and mI/Cho ratios in the left DLPFC were significantly higher in the sarcosine than the placebo group. In the sarcosine group, NAA/Cr, NAA/Cho, mI/Cr, mI/Cho ratios also significantly increased compared to baseline values. In the placebo group, only the NAA/Cr ratio increased. The addition of sarcosine to antipsychotic therapy for six months increased markers of neurons viability (NAA) and neurogilal activity (mI) with simultaneous improvement

    The effects of sarcosine on the processes driving prostate cancer (PCa) development remain still unclear. Herein, we show that a supplementation of metastatic PCa cells (androgen independent PC-3 and androgen dependent LNCaP) with sarcosine stimulates cells proliferation in vitro. Similar stimulatory effects were observed also in PCa murine xenografts, in which sarcosine treatment induced a tumor growth and significantly reduced weight of treated mice (p < 0.05). Determination of sarcosine metabolism-related amino acids and enzymes within tumor mass revealed significantly increased glycine, serine and sarcosine concentrations after treatment accompanied with the increased amount of sarcosine dehydrogenase. In both tumor types, dimethylglycine and glycine-N-methyltransferase were affected slightly, only. To identify the effects of sarcosine treatment on the expression of genes involved in any aspect of cancer development, we further investigated expression profiles of excised tumors using cDNA electrochemical microarray followed by validation using the semi-quantitative PCR. We found 25 differentially expressed genes in PC-3, 32 in LNCaP tumors and 18 overlapping genes. Bioinformatical processing revealed strong sarcosine-related induction of genes involved particularly in a cell cycle progression. Our exploratory study demonstrates that sarcosine stimulates PCa metastatic cells irrespectively of androgen dependence. Overall, the obtained data provides valuable information towards understanding the role of sarcosine in PCa progression and adds another piece of puzzle into a picture of sarcosine oncometabolic potential.

    A "sarcosine oxidase" was prepared from a creatinine-decomposing strain of Pseudomonas aeruginosa. The enzyme is inactivated by drying, lyophilization, and dialysis against distilled water. No dialyzable cofactor was found. Optimal activity of the enzyme is reached at pH 7.8. Enzyme activity is directly proportional to enzyme concentration and also to substrate concentration up to the point of saturation of enzyme with substrate molecules. One molecule of enzyme combines with one molecule of substrate. Data concerning the effect of temperature and of a variety of chemical compounds on the enzyme are presented. Its inactivation by heat follows the course of a first order reaction, and the critical thermal increment between 48° and 52°C. was calculated to be 103,000 calories per mol. The relationship of enzyme concentration to heat inactivation rates is illustrated. PMID:14778974

    Herein, we describe an ultrasensitive specific biosensing system for detection of sarcosine as a potential biomarker of prostate carcinoma based on Förster resonance energy transfer (FRET). The FRET biosensor employs anti-sarcosine antibodies immobilized on paramagnetic nanoparticles surface for specific antigen binding. Successful binding of sarcosine leads to assembly of a sandwich construct composed of anti-sarcosine antibodies keeping the Förster distance (Ro) of FRET pair in required proximity. The detection is based on spectral overlap between gold-functionalized green fluorescent protein and antibodies@quantum dots bioconjugate (λex 400 nm). The saturation curve of sarcosine based on FRET efficiency (F604/F510 ratio) was tested within linear dynamic range from 5 to 50 nM with detection limit down to 50 pM. Assembled biosensor was then successfully employed for sarcosine quantification in prostatic cell lines (PC3, 22Rv1, PNT1A), and urinary samples of prostate adenocarcinoma patients. PMID:25746688

    Rapid detection of sarcosine is a key requirement for both diagnosis and treatment of disease. We report here a simple yet sensitive colorimetric nanocomposite platform for rapid detection of sarcosine in alkaline media. The approach exploited the benefits of a rapid color-producing reaction between an organic indicator, 1,2-naphthoquinone-4-sulphonic acid sodium salt (NQS), and the analyte of sarcosine species as well as the good catalytic ability of graphene oxide (GO) to the formation of highly colored products due to its good water dispersibility, extremely large surface area and facile surface modification. As a result, a NQS functionalized GO nanocomposite through π-π stacking has been demonstrated to be useful as a highly efficient catalyst system for the selective and sensitive colorimetric determination of sarcosine by providing a nanocomposite-amplified colorimetric response. Meanwhile, the strategy offered excellent selectivity toward sarcosine species against other amino acids as well as a satisfying detection limit of 0.73 μM. More importantly, by using an electrochemical method, a credible sensing mechanism of GO nanocomposite-based colorimetric platform for a special analyte determination can be easily verified and elucidated, which also provides an attractive alternative to conventional characterization strategies.Rapid detection of sarcosine is a key requirement for both diagnosis and treatment of disease.

    Glutamate is the main excitatory neurotransmitter in the central nervous system. Dysfunction of the glutamatergic system plays an important and well-established role in the pathogenesis of schizophrenia. Agents with glutamatergic properties such as N-methyl-D-aspartate receptor coagonists (ie, glycine, D-cycloserine) and glycine transporter type 1 inhibitors (eg, sarcosine, bitopertin) are investigated in schizophrenia with special focus on negative and cognitive symptomatology. In this article, we describe a case of a 34-year-old woman with diagnosis of schizophrenia with persistent moderate negative and cognitive symptoms, a participant of the Polish Sarcosine Study (PULSAR) treated with olanzapine (25 mg per day) and venlafaxine (75 mg per day). During ten weeks of sarcosine administration (2 g per day) the patient’s activity and mood improved, but in the following 2 weeks, the patient reported decreased need for sleep, elevated mood, libido and general activity. We diagnosed drug-induced hypomania and recommended decreasing the daily dose of venlafaxine to 37.5 mg per day, which resulted in normalization of mood and activity in about 1 week. After this change, activity and mood remained stable and better than before adding sarcosine, and subsequent depressive symptoms were not noted. We describe here the second case report where sarcosine induced important affect changes when added to antidepressive and antipsychotic treatment, which supports the hypothesis of clinically important glutamate–serotonin interaction.

    Methylphenidate, a stimulant that activates dopaminergic and noradrenergic function, is an important agent in the treatment of attention deficit hyperactivity disorder (ADHD). Sarcosine, a glycine transporter-1 inhibitor, may also play a role in treating ADHD by modulating the glutamatergic neurotransmission system through activating N-methyl-D-aspartate type glutamate receptors. This study aimed to assess the efficacy of sarcosine in treating children with ADHD. We conducted a six-week, randomized, double-blind, placebo-controlled clinical trial. The primary outcome measures were those on the Inattention, Hyperactivity/impulsivity, and oppositional defiant disorder (ODD) subscales of the Swanson, Nolan, and Pelham, version IV scale. Efficacy and safety were measured bi-weekly. A total of 116 children with ADHD were enrolled. Among them, 48 (83%) of the 58 sarcosine recipients and 44 (76%) of the 58 placebo recipients returned for the first post-treatment visit. The missing data values were imputed by the last observation carry forward method. From a multiple linear regression analysis, using the generalized estimating equation approach, and an intention to treat analysis, the efficacy of sarcosine marginally surpassed that of placebo at weeks 2, 4, and 6, with p-values=0.01, 0.026, and 0.012, respectively, although only for ODD symptoms. Treatment of ADHD by sarcosine (0.03 g/kg/day) was well tolerated. Sarcosine could possibly be a novel agent for managing ODD symptoms in the context of ADHD. However, future larger-scale studies are warranted to optimize its dosage.

    The halophilic methanoarchaeon Methanohalophilus portucalensis FDF1T possesses the ability to synthesize the osmolyte betaine from its precursor, glycine, in response to extracellular salt stress through a three-step transmethylation process. Analysis of recombinant glycine sarcosine N-methyltransferase (rGSMT) and recombinant sarcosine dimethylglycine N-methyltransferase (rSDMT) from Escherichia coli indicated that betaine synthesis is rate-limited by rGSMT and is constitutively activated by rSDMT. Therefore, it is of interest to purify native GSMT from Methanohalophilus portucalensis to further compare its enzymatic characteristics and kinetics with rGSMT. In this study, native GSMT was purified through DEAE ion exchange and gel filtration chromatography with 95% purity. The enzymatic characteristics of GSMT and rGSMT showed similar trends of activities that were activated by high concentrations of monovalent cations. Both were feedback-inhibited by the end product, betaine, and competitively inhibited by S-adenosylhomocysteine (SAH). Native GSMT was 2-fold more sensitive to SAH than rGSMT. Notably, comparison of the kinetic parameters illustrated that the turnover rate of glycine methylation of GSMT was promoted by potassium ions, whereas rGSMT was activated by increasing protein-glycine binding affinity. These results suggest that GSMT and rGSMT may have different levels of post-translational modifications. Our preliminary mass spectrometry evidence indicated that there was no detectable phosphosite on GSMT after the complicated purification processes, whereas purified rGSMT still possessed 23.1% of its initial phosphorylation level. We believe that a phosphorylation-mediated modification may be involved in the regulation of this energy consuming betaine synthesis pathway during the stress response in halophilic methanoarchaea.

    Glutamate is the main excitatory neurotransmitter in the central nervous system. Dysfunction of the glutamatergic system plays an important role in the pathogenesis of schizophrenia. Therefore, glutamatergic agents such as N-methyl-D-aspartate receptor co-agonists (ie, glycine, D-cycloserine) and glycine transporter type 1 inhibitors (eg, sarcosine) are studied for their efficacy in ameliorating negative and cognitive symptomatology in patients with schizophrenia. We report the case of a 23-year-old schizophrenic patient treated with quetiapine and citalopram, who was offered concomitant sarcosine treatment. After obtaining an informed consent, we started administration of 2 g of sarcosine per day to treat persistent negative and cognitive symptoms. The patient’s activity and mood improved within 2 weeks, but in the following 2 weeks the patient reported increased drive, activity, libido, unpleasant inner tension, and irritability. We ruled out hypomania and decided to decrease the daily dose of sarcosine to 1 g, which resulted in reduction of drive and irritability. Activity and mood improved compared with his state before adding sarcosine. We suggest a sarcosine dose between 1 g and 2 g per day with an initial dose of 2 g, but if side effects occur, the dose should be decreased to 1 g per day. We would like to emphasize the clinically important glutamate-serotonin interaction during concomitant use of sarcosine, citalopram, and quetiapine in our patient, which may lead to serious discomfort.

    Toluene, a widely used and commonly abused organic solvent, produces various behavioral disturbances, including motor incoordination and cognitive impairment. Toluene alters the function of a large number of receptors and ion channels. Blockade of N-methyl-D-aspartate (NMDA) receptors has been suggested to play a critical role in toluene-induced behavioral manifestations. The present study determined the effects of various toluene doses on motor coordination, recognition memory, body temperature, and intracranial self-stimulation (ICSS) thresholds in mice. Additionally, the effects of sarcosine on the behavioral and physiological effects induced by toluene were evaluated. Sarcosine may reverse toluene-induced behavioral manifestations by acting as an NMDA receptor co-agonist and by inhibiting the effects of the type I glycine transporter (GlyT1). Mice were treated with toluene alone or combined with sarcosine pretreatment and assessed for rotarod performance, object recognition memory, rectal temperature, and ICSS thresholds. Toluene dose-dependently induced motor incoordination, recognition memory impairment, and hypothermia and lowered ICSS thresholds. Sarcosine pretreatment reversed toluene-induced changes in rotarod performance, novel object recognition, and rectal temperature but not ICSS thresholds. These findings suggest that the sarcosine-induced potentiation of NMDA receptors may reverse motor incoordination, memory impairment, and hypothermia but not the enhancement of brain stimulation reward function associated with toluene exposure. Sarcosine may be a promising compound to prevent acute toluene intoxications by occupational or intentional exposure. -- Highlights: ► Toluene induces impairments in Rotarod test and novel object recognition test. ► Toluene lowers rectal temperature and ICSS thresholds in mice. ► Sarcosine reverses toluene-induced changes in motor, memory and body temperature. ► Sarcosine pretreatment does not affect toluene

    Despite the obvious significance, the aqueous interactions of peptides remain incompletely understood. Their synthetic analogues called peptoids (poly-N-substituted glycines), have recently emerged as a promising biomimetic material, particularly due to their robust secondary structure and resistance to denaturation. We describe comparative near-edge x-ray absorption fine structure (NEXAFS) spectroscopy studies of aqueous sarcosine, the simplest peptoid, and alanine, its peptide isomer, interpreted by density functional theory calculations. The sarcosine nitrogen K-edge spectrum is blue-shifted with respect to that of alanine, in agreement with our calculations; we conclude that this shift results primarily from the methyl group substitution on the nitrogen of sarcosine. Our calculations indicate that the nitrogen K-edge spectrum of alanine differs significantly between dehydrated and hydrated scenarios, while that of the sarcosine zwitterion is less affected by hydration. In contrast, the computed sarcosine spectrum is greatly impacted by conformational variations, while the alanine spectrum is not. This relates to a predicted solvent dependence for alanine, as compared to sarcosine. Additionally, we show the theoretical nitrogen K-edge spectra to be sensitive to the degree of hydration, indicating that experimental X-ray spectroscopy may be able to distinguish between bulk and partial hydration, such as found in confined environments near proteins and in reverse micelles.

    Aim: Find changes in matrix metallopeptidase-9 (MMP-9) levels during augmentation of antipsychotic treatment with sarcosine and a relationship between schizophrenia symptoms severity and initial level of MMP-9. Method: Fifty-eight patients with diagnosis of schizophrenia with predominant negative symptoms participated in a six-month prospective RCT (randomized controlled trial). The patients received two grams of sarcosine (n = 28) or placebo (n = 30) daily. At the beginning, after six weeks and after six months MMP-9 levels were measured. Severity of symptomatology was assessed with the Positive and Negative Syndrome Scale (PANSS) and Calgary Depression Scale for Schizophrenia (CDSS). Results: MMP-9 serum levels were stable after six weeks and six months in both groups. We noted improvement in negative symptoms, general psychopathology and total PANSS score in sarcosine group compared to placebo; however, there was no correlations between serum MMP-9 concentrations and PANSS scores in all assessments. Initial serum MMP-9 concentrations cannot be used as an improvement predictor acquired during sarcosine augmentation. Conclusions: Our results indicate that either MMP-9 is not involved in the N-methyl-d-aspartate (NMDA)-dependent mechanism of sarcosine action in terms of clinical parameters or sarcosine induced changes in peripheral MMP-9 concentrations cannot be detected in blood assessments.

    This study was undertaken with the purpose to determine if there are changes in metabolic parameters during 6-month add-on treatment with sarcosine in patients with schizophrenia. This was a randomized double blind, placebo-controlled and parallel group study. Eligible participants were randomly assigned to receive 2g of sarcosine (n=30) or placebo (n=29). Sarcosine was administered as supplementation to the ongoing antipsychotic treatment. Augmentation with sarcosine had no effect on any of the analyzed cardiometabolic parameters. Also, augmentation with sarcosine had no effect on any of the analyzed body composition parameters. This is the first randomized placebo-controlled study to examine the metabolic safety of sarcosine in patients with schizophrenia. Clinically, this observation is of high importance considering how prevalent are metabolic abnormalities in patients with schizophrenia.

  12. Sarcosine and betaine crystals upon cooling: structural motifs unstable at high pressure become stable at low temperatures.

    The crystal structures of N-methyl derivatives of the simplest amino acid glycine, namely sarcosine (C3H7NO2) and betaine (C5H11NO2), were studied upon cooling by single-crystal X-ray diffraction and single-crystal polarized Raman spectroscopy. The effects of decreasing temperature and increasing hydrostatic pressure on the crystal structures were compared. In particular, we have studied the behavior upon cooling of those structural motifs in the crystals, which are involved in structural rearrangement during pressure-induced phase transitions. In contrast to their high sensitivity to hydrostatic compression, the crystals of both sarcosine and betaine are stable to cooling down to 5 K. Similarly to most α-amino acids, the crystal structures of the two compounds are most rigid upon cooling in the direction of the main structural motif, namely head-to-tail chains (linked via the strongest N-H···O hydrogen bonds and dipole-dipole interactions in the case of sarcosine, or exclusively by dipole-dipole interactions in the case of betaine). The anisotropy of linear strain in betaine does not differ much upon cooling and on hydrostatic compression, whereas this is not the case for sarcosine. Although the interactions between certain structural motifs in sarcosine and betaine weaken as a result of phase transitions induced by pressure, the same interactions strengthen when volume reduction results from cooling.

    Aqueous sarcosine salts are fast carbon dioxide (CO(2)) absorbents suitable for use in postcombustion CO(2) capture in coal-fired power plants. We have developed a detailed reaction scheme including all the reactions in the sarcosine-CO(2)-water system. All unknown rate and equilibrium constants were obtained by global data fitting. We investigated the temperature-dependent rate and equilibrium constants of the reaction between aqueous CO(2) and sarcosine using stopped-flow spectrophotometry, by following the pH changes over the wavelength range 400-700 nm via coupling to pH indicators. The corresponding rate and equilibrium constants ranged from 15.0 to 45.0 °C and were analyzed in terms of Arrhenius, Eyring, and van't Hoff relationships. The rate constant for the reaction between CO(2) and sarcosine to form the carbamate at 25.0 °C is 18.6(6) × 10(3) M(-1) s(-1), which is very high for an acyclic amine; its activation enthalpy is 59(1) kJ mol(-1) and the entropy is 33(4) J mol(-1) K(-1). In addition, we investigated the slow reaction between bicarbonate and sarcosine using (1)H nuclear magnetic resonance spectroscopy and report the corresponding rate and equilibrium constants at 25.0 °C. This rate constant is 5.9 × 10(-3) M(-1) s(-1).

    Oxygen reduction and sarcosine oxidation in monomeric sarcosine oxidase (MSOX) occur at separate sites above the si- and re-faces, respectively, of the flavin ring. Mutagenesis studies implicate Lys265 as the oxygen activation site. Substitution of Lys265 with a neutral (Met, Gln, or Ala) or basic (Arg) residue results in an {approx}10{sup 4}- or 250-fold decrease, respectively, in the reaction rate. The overall structure of MSOX and residue conformation in the sarcosine binding cavity are unaffected by replacement of Lys265 with Met or Arg. The side chain of Met265 exhibits the same configuration in each molecule of Lys265Met crystals and is nearly congruent with Lys265 in wild-type MSOX. The side chain of Arg265 is, however, dramatically shifted (4-5 {angstrom}) compared with Lys265, points in the opposite direction, and exhibits significant conformational variability between molecules of the same crystal. The major species in solutions of Lys265Arg is likely to contain a 'flipped-out' Arg265 and exhibit negligible oxygen activation, similar to Lys265Met. The 400-fold higher oxygen reactivity observed with Lys265Arg is attributed to a minor (<1%) 'flipped-in' Arg265 conformer whose oxygen reactivity is similar to that of wild-type MSOX. A structural water (WAT1), found above the si-face of the flavin ring in all previously determined MSOX structures, is part of an apparent proton relay system that extends from FAD N(5) to bulk solvent. WAT1 is strikingly absent in Lys265Met and Lys265Arg, a feature that may account for the apparent kinetic stabilization of a reductive half-reaction intermediate that is detectable with the mutants but not wild-type MSOX.

    Tris-sarcosine calcium chloride [(TSCC), (CH3NHCH2COOH)3CaCl2] is a uniaxial ferroelectric (FE) with a displacive second-order phase transition near Tc=130 K. A continuous range of solid solutions can be made by substituting Br for Cl, which lowers Tc to 0 K at ˜72% Br. Such a quantum critical point differs from that in pseudocubic FEs, such as O-18 SrTiO3 or doped KTaO3. For many years, this system was thought to have only two phases, paraelectric and FE, at ambient pressure. However, we find from dielectric and resonant ultrasound spectroscopy that there are four phase transitions in TSCC and in TSCC:Br (for 0 < Br < 40%): Order-disorder of the sarcosine methyl group at 185 K; displacive FE transition at 130 K (in pure TSCC); a second FE transition [previously hypothesized to be antiferroelectric (AFE) but probably not] at 64 K; and a new anomaly at ˜45 K which might be due to a phase transition or to Debye-like freezing of orientational disorder of some part of the sarcosine molecule. The probable sequence of structures is (upon cooling): Pnma with Z=4(D2h16) ambient 500 K > T > 185 K, disordered; Pnma with Z=4(D2h16)185K>T>130K (ordered); Pn21a with Z=4(C2v9)130K>T>64K (FE); P21a (C2h5) with Z =4, 64 K > T > 45 K (not AFE); T < 45 K, unknown structure. A sixth hexagonal structure at high temperatures (>500 K) is hypothesized to be D6h3(P63/mcm) with Z =2, but the samples decompose first at 503 K (230 °C).

    The aim of this pilot study is to evaluate sarcosine, uracil, and kynurenic acid in urine as potential biomarkers in prostate cancer detection and progression monitoring. Sarcosine, uracil, and kynurenic acid were measured in urine samples of 32 prostate cancer patients prior to radical prostatectomy, 101 patients with increased prostate-specific antigen prior to ultrasonographically-guided prostatic biopsy collected before and after prostatic massage, and 15 healthy volunteers (controls). The results were related to histopathologic data, Gleason score, and PSA (Prostate Specific Antigen). Metabolites were measured after analysis of urine samples with Ultra-High Performance Liquid Chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) instrumentation. Multivariate, nonparametric statistical tests including receiver operating characteristics analyses, one-way analysis of variance (Kruskal–Wallis test), parametric statistical analysis, and Pearson correlation, were performed to evaluate diagnostic performance. Decreased median sarcosine and kynurenic acid and increased uracil concentrations were observed for patients with prostate cancer compared to participants without malignancy. Results showed that there was no correlation between the concentration of the studied metabolites and the cancer grade (Gleason score <7 vs. ≥7) and the age of the patients. Evaluation of biomarkers by ROC (Receiving Operating Characteristics) curve analysis showed that differentiation of prostate cancer patients from participants without malignancy was not enhanced by sarcosine or uracil levels in urine. In contrast to total PSA values, kynurenic acid was found a promising biomarker for the detection of prostate cancer particularly in cases where collection of urine samples was performed after prostatic massage. Sarcosine and uracil in urine samples of patients with prostate cancer were not found as significant biomarkers for the diagnosis of prostate cancer. None of the

    The determination of creatinine levels in biological fluids is an increasingly important clinical requirement. Amperometric biosensors have been developed based on a three-enzyme system which converts creatinine to amperometrically measurable hydrogen peroxide. The development of the amperometric creatinine biosensor has been slow due the complexity of the three-enzyme system. This paper, the first of three, discusses the chemical modification of sarcosine oxidase and the immobilization and stabilization of this enzyme using polyurethane prepolymers. Sarcosine oxidase was completely inactivated after modification using poly(ethylene glycol) activated with isocyanate. The addition of a competitive inhibitor during enzyme modification was effective in protecting the enzyme from inactivation. Computational analysis of the structure of sarcosine oxidase suggests that there is a lysine in the active site that may be hyper-reactive. The enzyme was irreversibly immobilized using polyurethane prepolymers and retained significant activity. The enzyme's half-life at 37 degrees C increased from seven days to more than 50 days after immobilization.

    Sarcosine has been identified as a potential prostate cancer marker. To provide determination of this compound, a number of methods are developing. In this study, we optimized a method for its separation by hydrophilic interaction LC with electrochemical detection (ED). Due to the fact that mobile phases commonly used for this type of separation altered the LODs measured by electrochemical detectors, we applied postcolumn dosing of buffer suitable for ED. The optimized conditions were mobile phase A acetonitrile, mobile phase B water in the ratio A/B 70:30, with postcolumn addition of mobile phase C (200 mM phosphate buffer pH 9). The optimal mixing ratio was A + B/C 1:1 with a flow rate of 0.80 mL/min (0.40 + 0.40 mL/min) and detection potential of 1000 mV. Due to the optimization of the parameters for effective separation, which had to meet the optimal parameters of ED, we reached a good resolution for separation also with a good LOD (100 nM). In addition, we successfully carried out sarcosine analysis bound on our modified paramagnetic microparticles with the ability to preconcentrate sarcosine isolated from artificial urine.

    Methyltransferases play crucial roles in many cellular processes, and various regulatory mechanisms have evolved to control their activities. For methyltransferases involved in biosynthetic pathways, regulation via feedback inhibition is a commonly employed strategy to prevent excessive accumulation of the pathways’ end products. To date, no biosynthetic methyltransferases have been characterized by X-ray crystallography in complex with their corresponding end product. Here, we report the crystal structures of the glycine sarcosine N-methyltransferase from the halophilic archaeon Methanohalophilus portucalensis (MpGSMT), which represents the first structural elucidation of the GSMT methyltransferase family. As the first enzyme in the biosynthetic pathway of the osmoprotectant betaine, MpGSMT catalyzes N-methylation of glycine and sarcosine, and its activity is feedback-inhibited by the end product betaine. A structural analysis revealed that, despite the simultaneous presence of both substrate (sarcosine) and cofactor (S-adenosyl-L-homocysteine; SAH), the enzyme was likely crystallized in an inactive conformation, as additional structural changes are required to complete the active site assembly. Consistent with this interpretation, the bound SAH can be replaced by the methyl donor S-adenosyl-L-methionine without triggering the methylation reaction. Furthermore, the observed conformational state was found to harbor a betaine-binding site, suggesting that betaine may inhibit MpGSMT activity by trapping the enzyme in an inactive form. This work implicates a structural basis by which feedback inhibition of biosynthetic methyltransferases may be achieved. PMID:27934872

    The effect of N-methylation on sequence scrambling in the fragmentation of b5 ions has been investigated by studying a variety of peptides containing sarcosine (N-methylglycine). The product ion mass spectra for the b5 ions derived from Sar-A-A-A-Y-A and Sar-A-A-Y-A-A show only minor signals for non-direct sequence ions the major fragmentation reactions occurring from the unrearranged structures. This is in contrast to the b5 ions where the Sar residue is replaced by Ala and sequence scrambling occurs. The b5 ion derived from Y-Sar-A-A-A-A shows a product ion mass spectrum essentially identical to the spectrum of the b5 ion derived from Sar-A-A-A-Y-A, indicating that in the former case macrocyclization has occurred but the macrocyclic form shows a strong preference to reopen to put the Sar residue in the N-terminal position. Similar results were obtained in the comparison of b5 ions derived from A-Sar-A-A-Y-A and Sar-A-A-Y-A-A. The product ion mass spectra of the MH(+) ions of Y-Sar-A-A-A-A and A-Sar-A-A-Y-A show substantial signals for non-direct sequence ions indicating that fragmentation of the MH(+) ions channels extensively through the respective b5 ions and further fragmentation of these species.

    Sarcosine is a competitive inhibitor of glycine type 1 transporter. We hypothesized that it may have analgesic and anti-neuropathic efficacy by a dual action: affecting neurotransmission in the prefrontal cortex as well as within the spinal cord. In rats with spared nerve injury (SNI) oral sarcosine reduced mechanical sensitivity for the injured limb (anti-neuropathy or anti-allodynia) as well as for the uninjured limb (analgesia), showing better dose efficacy for the injured limb. Intrathecal administration of sarcosine was more effective in reducing mechanical sensitivity for the uninjured paw. In contrast, prefrontal cortex infusions of sarcosine acutely reduced mechanical sensitivity for the injured paw. Repeated daily oral sarcosine induced anti-neuropathy, observed only after days of repeated treatment; this long term effect disappeared a few days after treatment cessation. The findings indicate that manipulating glycine T1 transporter at multiple central sites can induce acute analgesia, as well as acute and long-term reduction in neuropathic pain behavior. Analgesic effects seem primarily mediated through spinal cord circuitry while anti-neuropathic effects through prefrontal cortex circuitry, most likely through distinct molecular pathways. The results suggest that such an approach may provide a novel venue for treating clinical pain conditions. PMID:19577367

    Herein, we describe the preparation of liposomes with folate-targeting properties for the encapsulation of anti-sarcosine antibodies (antisarAbs@LIP) and sarcosine (sar@LIP). The competitive inhibitory effects of exogenously added folic acid supported the role of folate targeting in liposome internalization. We examined the effects of repeated administration on mice PC-3 xenografts. Sar@LIP treatment significantly increased tumor volume and weight compared to controls treated with empty liposomes. Moreover, antisarAbs@LIP administration exhibited a mild antitumor effect. We also identified differences in gene expression patterns post-treatment. Furthermore, Sar@LIP treatment resulted in decreased amounts of tumor zinc ions and total metallothioneins. Examination of the spatial distribution across the tumor sections revealed a sarcosine-related decline of the MT1X isoform within the marginal regions but an elevation after antisarAbs@LIP administration. Our exploratory results demonstrate the importance of sarcosine as an oncometabolite in PCa. Moreover, we have shown that sarcosine can be a potential target for anticancer strategies in management of PCa. PMID:27646588

    Peroxidase-catalysed reactions are used in a wide variety of analytical applications, most of them based on the final quantification of hydrogen peroxide. Clinical tests for glucose, cholesterol, creatine, creatinine or uric acid in blood or urine and enzyme-linked immunosorbent assays for pesticides, hepatitis or acquired immune deficiency syndrome are good examples of such applications. The most widely used and commercially available peroxidase for biotechnological processes and analytical applications is horseradish peroxidase followed, although in much lower proportion, by soybean peroxidase. The high commercial interest in peroxidases has led to the search for new sources of these enzymes. This work describes the analytical use of lentil plant peroxidase (LPP), which is a new peroxidase extracted from lentil plants (Lens culinaris Medikus); an abundant post-harvest agricultural waste in the area of Castilla y León (Spain). A procedure for the quantification of hydrogen peroxide in urine is first proposed using crude extract of lentil plant instead of the purified enzyme. This procedure is then applied to the determination of sarcosine; a natural amino acid that has attracted considerable interest in clinical diagnostics since urinary sarcosine was proposed and later questioned as a biomarker for prostate cancer. Under the action of sarcosine oxidase, sarcosine is oxidized by molecular oxygen to give glycine, formaldehyde and hydrogen peroxide that is quantified according to the previously proposed procedure. The limit of detection for both hydrogen peroxide and sarcosine is around 5 × 10(-7) M. In the determination of sarcosine, the high selectivity of the overall enzymatic reaction, the simple sample treatment and instrumentation, the high-sample throughput and the use of LPP in the plant extract instead of the purified enzyme provide a rapid and inexpensive procedure with characteristics very suitable for routine analysis in a clinical laboratory.

    The flavoenzyme monomeric sarcosine oxidase (MSOX) catalyzes a complex set of reactions currently lacking a consensus mechanism. A key question that arises in weighing competing mechanistic models of MSOX function is to what extent ingress of O2 from the solvent (and its egress after an unsuccessful oxidation attempt) limits the overall catalytic rate. To address this question, we have applied to the MSOX/O2 system the relatively new simulation method of Markovian milestoning molecular dynamics simulations, which, as we recently showed [ Yu et al. J. Am. Chem. Soc. 2015 , 137 , 3041 ], accurately predicted the entry and exit kinetics of CO in myoglobin. We show that the mechanism of O2 entry and exit, in terms of which possible solvent-to-active-site channels contribute to the flow of O2, is sensitive to the presence of the substrate-mimicking competitive inhibitor 2-furoate in the substrate site. The second-order O2 entry rate constants were computed to be 8.1 × 10(6) and 3.1 × 10(6) M(-1) s(-1) for bound and apo MSOX, respectively, both of which moderately exceed the experimentally determined second-order rate constant of (2.83 ± 0.07) × 10(5) M(-1) s(-1) for flavin oxidation by O2 in MSOX. This suggests that the rate of flavin oxidation by O2 is likely not strongly limited by diffusion from the solvent to the active site. The first-order exit rate constants were computed to be 10(7) s(-1) and 7.2 × 10(6) s(-1) for the apo and bound states, respectively. The predicted faster entry and slower exit of O2 for the bound state indicate a longer residence time within MSOX, increasing the likelihood of collisions with the flavin isoalloxazine ring, a step required for reduction of molecular O2 and subsequent reoxidation of the flavin. This is also indirectly supported by previous experimental evidence favoring the so-called modified ping-pong mechanism, the distinguishing feature of which is an intermediate complex involving O2, the flavin, and the oxidized

    Sarcosine, an endogenous amino acid, is a competitive inhibitor of the type I glycine transporter and an N-methyl-d-aspartate receptor (NMDAR) coagonist. Recently, we found that sarcosine, an NMDAR enhancer, can improve depression-related behaviors in rodents and humans. This result differs from previous studies, which have reported antidepressant effects of NMDAR antagonists. The mechanisms underlying the therapeutic response of sarcosine remain unknown. This study examines the role of mammalian target of rapamycin (mTOR) signaling and α-amino-3-hydroxy-5-methylisoxazole-4-propionate receptor (AMPAR) activation, which are involved in the antidepressant-like effects of several glutamatergic system modulators. The effects of sarcosine in a forced swim test (FST) and the expression levels of phosphorylated mTOR signaling proteins were examined in the absence or presence of mTOR and AMPAR inhibitors. In addition, the influence of sarcosine on AMPAR trafficking was determined by analyzing the phosphorylation of AMPAR subunit GluR1 at the PKA site (often considered an indicator for GluR1 membrane insertion in neurons). A single injection of sarcosine exhibited antidepressant-like effects in rats in the FST and rapidly activated the mTOR signaling pathway, which were significantly blocked by mTOR inhibitor rapamycin or the AMPAR inhibitor 2,3-dihydroxy-6-nitro-7-sulfamoyl-benzo(f)quinoxaline (NBQX) pretreatment. Moreover, NBQX pretreatment eliminated the ability of sarcosine to stimulate the phosphorylated mTOR signaling proteins. Furthermore, GluR1 phosphorylation at its PKA site was significantly increased after an acute in vivo sarcosine treatment. The results demonstrated that sarcosine exerts antidepressant-like effects by enhancing AMPAR-mTOR signaling pathway activity and facilitating AMPAR membrane insertion.

    The aim of this study is to investigate the expression of sarcosine metabolism related proteins according to androgen receptor (AR) and HER-2 status in estrogen receptor (ER) negative breast cancer and to analyze its clinical implications. Tissue microarray was constructed for a total of 334 cases of ER negative breast cancer. Immunohistochemical stain was conducted for sarcosine metabolism related proteins such as glycine N-methyltransferase (GNMT), sarcosine dehydrogenase (SARDH), and l-pipecolic acid oxidase (PIPOX). There were 131 AR positive, 205 AR negative cases and 143 HER-2 positive, 193 HER-2 negative cases. When subdividing into four groups according to AR and HER-2 status, there were 55 AR(+)/HER-2(-) cases, 76 AR(+)/HER-2(+) cases, 67 AR(-)/HER-2(+) cases and 138 AR(-)/HER-2(-) cases. GNMT and PIPOX expression was highest in the AR(+)/HER-2(-) group while expressed lowest in the AR(-)/HER-2(-) group (P<0.001). Stromal PIPOX expression was highest in the AR(-)/HER-2(+) group and lowest in the AR(-)/HER-2(-) group (P=0.010). GNMT and PIPOX expression was higher in the AR positive group compared with those of AR negative group (P=0.001, and P<0.001, respectively), while tumoral and stromal PIPOX expression showed a significant association with HER-2 positivity (P=0.006, and P=0.005, respectively). AR positive group had the highest ratio of low sarcosine type while the AR negative group had the highest ratio of null type (P<0.001). In conclusion, ER negative breast cancer showed different expression of sarcosine metabolism related proteins according to AR and HER-2 status. GNMT and PIPOX expression was high in the AR positive group while tumoral and stromal PIPOX expression was high in the HER-2 positive group. PMID:26339363

  8. The glutamatergic compounds sarcosine and N-acetylcysteine ameliorate prepulse inhibition deficits in metabotropic glutamate 5 receptor knockout mice

    Rationale Mice lacking metabotropic glutamate receptors 5 (mGluR5) exhibit reduced glutamatergic function and behavioral abnormalities, including deficits in prepulse inhibition (PPI) of the startle response that may be relevant to schizophrenia. Thus, these mice are an animal model that may be used for preclinical evaluation of potentially new classes of antipsychotic compounds. Recent clinical studies have suggested several compounds that modulate glutamatergic transmission through distinct mechanisms, such as potentiation of the N-methyl-d-aspartate (NMDA) receptor glycine site, activation of group II mGluR, and activation of glutamate-cysteine antiporters, as being efficacious in the treatment of schizophrenia. Objectives The aim of this work is to evaluate the effects of sarcosine (a selective inhibitor of the glycine transporter 1 [GlyT1]), LY379268 (a group II mGluR agonist), and N-acetylcysteine (a cysteine prodrug that indirectly activates cystine-glutamate antiporters to increase glutamate levels in the extrasynaptic space) on PPI deficits in mGluR5 knockout mice. Results Sarcosine and N-acetylcysteine, but not LY379268, ameliorated PPI deficits in mGluR5 knockout mice. The ability of N-acetylcysteine to restore PPI deficits was not blocked by the group II mGluR antagonist LY341495, indicating that the effects of N-acetylcysteine were not attributable to activation of group II mGluRs by glutamate. Conclusions These findings provide evidence that the interactions between mGluR5 and NMDA receptors are involved in the regulation of PPI and suggest that activation of glutamate receptors, other than group II receptors, by increased endogenous glutamate transmission, may ameliorate the behavioral abnormalities associated with mGluR5 deficiency.

    We have synthesized a novel series of N-substituted sarcosines, analogues of NFPS (N-[3-(biphenyl-4- yloxy)-3-(4-fluorophenyl)propyl]-N-methylglycine), as type-1 glycine transporter (GlyT-1) inhibitors. Several compounds incorporated a diazine ring inhibited recombinant hGlyT-1b expressed permanently in CHO cells and GlyT-1 in rat brain synaptosomal preparations. A structure-activity relationship for the newly synthesized compounds was obtained and discussed on the ground of their GlyT-1 inhibitory potencies. Replacement of the biphenyl-4-yloxy moiety in NFPS with a 5-pyridazinylphenoxy moiety (compounds 3, 4, 5, and 6) or a 2-phenyl-5- pyridazinyloxy moiety (compounds 10, 11, and 12) afforded compounds exhibiting potent inhibition on GlyT-1 activity. The GlyT-1 inhibitory properties of NFPS analogues, in which sarcosine was closed into a ring forming (methylamino)pyridazine-3-(2H)-one, were markedly reduced (compounds 13 and 14). The pyridazine-containing GlyT-1 inhibitors with in vitro GlyT-1 inhibitory potency also enhanced extracellular glycine concentrations in conscious rat striatum as was measured by microdialysis technique. In contrast to NFPS, sarcosine-based pyridazine containing GlyT-1 inhibitors failed to evoke compulsive running behavior whereas they inhibited phencyclidine- induced hypermotility in mice. It is believed that increase of extracellular concentrations of glycine by inhibition of its reuptake may probably influence positively glutamate N-methyl-D-aspartate (NMDA)-type ionotropic receptors in the central nervous system. This may have importance in the treatment of neuropsychiatric disorders associated with hypofunctional NMDA receptor-mediated glutamatergic neurochemical transmission. Thus, impaired NMDA receptor functions have been shown to be involved in the development of the negative symptoms and the cognitive deficit of schizophrenia and the treatment of these symptoms is the possible clinical indication of GlyT-1 inhibitors including

    Nosocomial wound infections by antibiotic-resistant Pseudomonas aeruginosa strains have increasing importance in hospitals. Outer membrane proteins of the bacterium have strong influence on its resistance to antibiotics. In the current study, a parallel proteomic approach was applied to analysis of sarcosine-insoluble outer membrane fraction of P. aeruginosa responding to ampicilin, kanamycin and tetracycline resistances. Eleven differential proteins with 15 spots were determined and then identified by MALDI-TOF/MS, in which four with increased OprF, MexA, OmpH, and decreased hypothetical protein (NCBI No. 15599856), six with increased OprF, OmpH, hypothetical protein (NCBI No. 15599183) and decreased OprG, MexA, conserved hypothetical protein (NCBI No. 15600371), and eight with increased OprF, MexA, OprL, probable Omp (NCBI No. 15599856), probable secretion protein (NCBI No. 15600167), OprD and decreased OprG, conserved hypothetical protein (NCBI No. 15600371) responded to ampicilin, kanamycin, and tetracycline resistances, respectively. With the exception of OprF, the other differential proteins did not show the same behaviors against the three antibiotic resistances. Compared with our previous report on E. coli Omps responding to ampicilin and tetracycline resistances, which was only a protein difference in quality between the two antibiotics, P. aeruginosa showed significant diversity against the three antibiotics. Our findings might provide valuable data for an understanding of antibiotic-resistant difference between different species of bacteria. Meanwhile, these proteins shared by different bacteria or a bacterium against different antibiotics may provide universal targets for the development of new drugs that control antibiotic-resistant bacteria.

    Dark-induced growth (skotomorphogenesis) is primarily characterized by rapid elongation of the hypocotyl. We have studied the role of abscisic acid (ABA) during the development of young tomato (Solanum lycopersicum L.) seedlings. We observed that ABA deficiency caused a reduction in hypocotyl growth at the level of cell elongation and that the growth in ABA-deficient plants could be improved by treatment with exogenous ABA, through which the plants show a concentration dependent response. In addition, ABA accumulated in dark-grown tomato seedlings that grew rapidly, whereas seedlings grown under blue light exhibited low growth rates and accumulated less ABA. We demonstrated that ABA promotes DNA endoreduplication by enhancing the expression of the genes encoding inhibitors of cyclin-dependent kinases SlKRP1 and SlKRP3 and by reducing cytokinin levels. These data were supported by the expression analysis of the genes which encode enzymes involved in ABA and CK metabolism. Our results show that ABA is essential for the process of hypocotyl elongation and that appropriate control of the endogenous level of ABA is required in order to drive the growth of etiolated seedlings.

    Glutamatergic system, the main stimulating system of the brain, plays an important role in the pathogenesis of schizophrenia. Hippocampus, a structure crucial for memory and cognitive functions and rich in glutamatergic neurons, is a natural object of interest in studies on psychoses. Sarcosine, a glycine transporter (GlyT-1) inhibitor influences the function of NMDA receptor and glutamate-dependent transmission. The aim of the study was to assess the effects of sarcosine on metabolism parameters in the left hippocampus in patients with schizophrenia. Assessments were performed using proton nuclear magnetic resonance ((1)H NMR) spectroscopy (1.5T). Fifty patients diagnosed with schizophrenia (DSM-IV-TR), with dominant negative symptoms, in stable clinical condition and stable antipsychotics doses were treated either with sarcosine (n=25) or placebo (n=25). Spectroscopic parameters were evaluated within groups and between two groups before and after 6-month intervention. All patients were also assessed with the Positive and Negative Syndrome Scale (PANSS). In the sarcosine group, after 6-month treatment, we found significant decrease in hippocampal Glx/Cr (Glx-complex of glutamate, glutamine and GABA, Cr-creatine) and Glx/Cho (Cho-choline), while N-acetylaspartate (NAA), myo-inositol (mI), Cr and Cho parameters remained stable along the study and also did not differ significantly between both groups. This is the first study showing that a pharmacological intervention in schizophrenia, particularly augmentation of the antypsychotic treatment with sarcosine, may reverse the pathological increase in glutamatergic transmission in the hippocampus. The results confirm involvement of glutamatergic system in the pathogenesis of schizophrenia and demonstrate beneficial effects of GlyT-1 inhibitor on the metabolism in the hippocampus and symptoms of schizophrenia.

    Following incubation of methylglyoxal and creatine under physiological conditions, N-(4-methyl-5-oxo-1-imidazolin-2-yl)sarcosine (MG-HCr) was isolated and identified by NMR and mass spectrometry. Due to its rapid formation, MG-HCr represents a specific product following "scavenging" of methylglyoxal by creatine. Using hydrophilic interaction chromatography coupled to mass spectrometry, MG-HCr was analyzed in urine samples of healthy volunteers. Daily MG-HCr excretion of nonvegetarians ranged from 0.35 to 3.84 μmol/24 h urine (median: 0.90 μmol/24 h urine) and of vegetarians from 0.11 to 0.31 μmol/24 h urine (median: 0.19 μmol/24 h urine), indicating that formation of MG-HCr in vivo is influenced by the dietary intake of creatine. The trapping of methylglyoxal by creatine may delay the formation of advanced glycation compounds in vivo and, therefore, could be of special importance in situations in which the body has to deal with pathophysiologically increased amounts of dicarbonyl compounds ("carbonyl stress"), for instance in diabetic patients.

    The regulation of glycine concentrations within excitatory synapses is poorly understood and it has been proposed that the GLYT1 subtypes of glycine transporters play a critical role in determining resting concentrations of glycine. Selective GLYT1 inhibitors may provide pharmacological tools to probe the dynamics of synaptic glycine concentrations, which may influence the activation properties of NMDA receptor activity.We have characterized the selectivity and mechanism of action of the glycine transport inhibitor N[3-(4′-fluorophenyl)-3-(4′-phenylphenoxy)propyl]sarcosine (NFPS). The glycine transporters, GLYT1a, b and c and GLYT2a were expressed in Xenopus laevis oocytes and two electrode voltage clamp techniques and radiolabelled 3H-glycine flux measurements were used to characterize the effects of NFPS on glycine transport.NFPS inhibits glycine transport by the GLYT1a, b and c subtypes of glycine transporters, but has no effect on the GLYT2a subtype of transporter. We show that NFPS does not attain its specificity via an interaction with the Na+, Cl− or glycine site, nor does it act at an intracellular site. NFPS inhibition of glycine transport is time and concentration dependent and inhibition of transport by NFPS persists after washout of NFPS from the bath solution, which suggests that inhibition by NFPS is long lasting.

    Cd(II) complexes with glycine (gly) and sarcosine (sar) were studied by glass electrode potentiometry, direct current polarography, virtual potentiometry, and molecular modelling. The electrochemically reversible Cd(II)-glycine-OH labile system was best described by a model consisting of M(HL), ML, ML2, ML3, ML(OH) and ML2(OH) (M = Cd(II), L = gly) with the overall stability constants, as log beta, determined to be 10.30+/-0.05, 4.21+/-0.03, 7.30+/-0.05, 9.84+/-0.04, 8.9+/-0.1, and 10.75+/-0.10, respectively. In case of the electrochemically quasi-reversible Cd(II)-sarcosine-OH labile system, only ML, ML2 and ML3 (M = Cd(II), L = sar) were found and their stability constants, as log beta, were determined to be 3.80+/-0.03, 6.91+/-0.07, and 8.9+/-0.4, respectively. Stability constants for the ML complexes, the prime focus of this work, were thus established with an uncertainty smaller than 0.05 log units. The observed departure from electrochemical reversibility for the Cd-sarcosine-OH system was attributed mainly to the decrease in the transfer coefficient alpha. The MM2 force field, supplemented by additional parameters, reproduced the reported crystal structures of diaqua-bis(glycinato-O,N)nickel(II) and fac-tri(glycinato)-nickelate(II) very well. These parameters were used to predict structures of all possible isomers of (i) [Ni(H2O)4(gly)]+ and [Ni(H2O)4(sar)]+; and (ii) [Ni(H2O)3(IDA)] and [Ni(H2O)3(MIDA)] (IDA = iminodiacetic acid, MIDA = N-methyl iminodiacetic acid) by molecular mechanics/simulated annealing methods. The change in strain energy, deltaU(str), that accompanies the substitution of one ligand by another (ML + L' --> ML' + L), was computed and a strain energy deltaU(str) = +0.28 kcal mol(-1) for the reaction [Ni(H2O)4(gly)]+ + sar --> [Ni(H2O)4(sar)]+ + gly was found. This predicts the monoglycine complex to be marginally more stable. By contrast, for the reaction [Ni(H2O)3IDA] + MIDA --> [Ni(H2O)3MIDA] + IDA, deltaU(str) = -0.64 kcal mol(-1

    The recent identification of a novel binding site for angiotensin (Ang) II as the peptidase neurolysin (E.C. 3.4.24.16) has implications for the renin-angiotensin system (RAS). This report describes the distribution of specific binding of 125I-Sarcosine1, Isoleucine8 Ang II (125I-SI Ang II) in neurolysin knockout mouse brains compared to wild-type mouse brains using quantitative receptor autoradiography. In the presence of p-chloromercuribenzoic acid (PCMB), which unmasks the novel binding site, widespread distribution of specific (3 µM Ang II displaceable) 125I-SI Ang II binding in 32 mouse brain regions was observed. Highest levels of binding >700 fmol/g initial wet weight were seen in hypothalamic, thalamic and septal regions, while the lowest level of binding <300 fmol/g initial wet weight was in the mediolateral medulla. 125I-SI Ang II binding was substantially higher by an average of 85% in wild-type mouse brains compared to neurolysin knockout brains, suggesting the presence of an additional non-AT1, non-AT2, non-neurolysin Ang II binding site in the mouse brain. Binding of 125I-SI Ang II to neurolysin in the presence of PCMB was highest in hypothalamic and ventral cortical brain regions, but broadly distributed across all regions surveyed. Non-AT1, non-AT2, non-neurolysin binding was also highest in the hypothalamus but had a different distribution than neurolysin. There was a significant reduction in AT2 receptor binding in the neurolysin knockout brain and a trend towards decreased AT1 receptor binding. In the neurolysin knockout brains, the size of the lateral ventricles was increased by 56% and the size of the mid forebrain (−2.72 to +1.48 relative to Bregma) was increased by 12%. These results confirm the identity of neurolysin as a novel Ang II binding site, suggesting that neurolysin may play a significant role in opposing the pathophysiological actions of the brain RAS and influencing brain morphology.

    Objectives: The objectives of this study were to evaluate the capability of a research volunteer registry to retain community-dwelling African American older adults, and to explore demographic and health factors associated with retention. Method: A logistic regression model was used to determine the influence of demographics, health factors, and registry logic model activities on retention in a sample of 1,730 older African American adults. Results: Almost 80% of participants active in the volunteer research registry between January 2012 and June 2015 were retained. Employment, being referred to research studies, a higher number of medical conditions, and more follow-up contacts were associated with an increased likelihood of retention. Older age, more months in the registry, and more mobility problems decreased the likelihood of retention. Discussion: These results suggest the Michigan Center for Urban African American Aging Research logic model promotes retention through involving older African American adults in research through study referrals and intensive follow-up. The loss of participants due to age- and mobility-related issues indicate the registry may be losing its most vulnerable participants. PMID:28138501

    Buss, Paulo Marchiori; de Carvalho, Antonio Ivo

    2007-01-01

    The evolution of health promotion within the Brazilian health system is examined, including an assessment of the intersectoral and development policies that have influenced the process. Particular attention is paid to the legal characteristics of the Unified Health System. Human resources formation and research initiatives in health promotion are outlined, with a summary of the obstacles that need to be overcome in order to ensure the effective implementation of health promotion in the future. Up to the end of the 20th Century health promotion was not used as a term in the Brazilian public heath context. Health promoting activities were concentrated in the area of health education, although targeting the social determinants of health and the principle of intersectoral action were part of the rhetoric. The situation has changed during the last decade, with the publication of a national policy of health promotion, issued by the Ministry of Health and jointly implemented with the States and Municipals Health Secretaries. More recently there has been a re-emergence of the discourse on the social determinants of health and the formation of intersectoral public policies as the basis of a comprehensive health promotion. Health promotion infrastructure, particularly around human resources and financing, requires strengthening in order to ensure capacity and sustainability in health promotion practice.

    1979-01-01

    To reverse the current trend of a significant decline worldwide in breast feeding means reeducation of medical and health personnel as well as the general public. Programs to promote breast feeding require the commitment of governments, with support from various ministries including health, education, labor, community development and judiciary. Examples of what 3 developing countries--Jamaica, Colombia and Thailand--are doing to promote breast feeding are reported. A large scale breast feeding campaign was launched in Jamaica in October 1977. The 3 phases of the campaign were: 1) preliminary surveys and research and motivation of professional, voluntary and extension groups through training seminars, panel discussions, and meetings; 2) promotion of breast feeding via mass media and motivation of target groups by trained personnel; and 3) evaluation of the campaign. A survey undertaken in 1978 showed that the breast feeding messages had achieved the desired effect--more mothers practiced breast feeding. In Colombia the breast feeding campaign emphasized non-formal education through the use of games and pictures. A game is used which is usually initiated by a health worker in the waiting room of a health center and involves the mothers, the general public, and sometimes the professional personnel. Through reading and interpreting rhymed breast feeding messages, the participants exchange opinions and experiences. Before starting a campaign to encourage low-income urban and semi-urban mothers to breast feed, the National Food and Nutrition Committee of Thailand pretested slogans and posters designed for the promotion of breast feeding. Posters develpoed in accordance with the suggestions made by the women were tested among 126 pregnant and lactating women. The Committee decided which picture to print for low-income and rural audiences and which to print for middle-class audiences.

    Clearly, academic endeavour has to be the single most important criterion for appointment to an academic position and for subsequent promotion. It is rare for excellence either in teaching or clinical practice to offset a poor publication record. However, the pressure to publish and gain related grant income can lead to problems in the normal academic pursuits of a department or institution. These and other related issues will be explored in this editorial.

    The objective of this Bicycle Promotion Plan is to outline a set of recommendations and supporting strategies for implementation by the US DOE toward increased use of the bicycle for energy conservation. The recommendations are designed in such a way as to function in concert with: (1) bicycle programs administered by other Federal government agencies; and (2) related programs and activities already sponsored by DOE. The approach to preparation of the Plan involved a review of all current and planned bicycle promotion programs at the Federal level as well as a review of the array of lierature on the subject. The UniWorld project staff also interacted with several DOE program offices, in order to determine the extent to which they might appropriately contribute to the implementation of bicycle promotional efforts. A synthesis of all the information gathered was published in January of 1981 as a part of the project (The Bicycle Program Review). Based upon this information and an examination of the barriers to bicycle use identified by bicycle transportation specialists in the field, UniWorld developed a series of the most potentially effective recommendations and program strategies for implementation by DOE. The recommendations address activities that could be undertaken in conjunction with existing DOE programs, new developments that might be considered to fulfill critical needs in the field, and interagency efforts that DOE could play a role in.

  4. The dynamics of mobile promoters: Enhanced stability in promoter regions.

    PubMed

    Rabbani, Mahnaz; Wahl, Lindi M

    2016-10-21

    Mobile promoters are emerging as a new class of mobile genetic elements, first identified by examining prokaryote genome sequences, and more recently confirmed by experimental observations in bacteria. Recent datasets have identified over 40,000 putative mobile promoters in sequenced prokaryote genomes, however only one-third of these are in regions of the genome directly upstream from coding sequences, that is, in promoter regions. The presence of many promoter sequences in non-promoter regions is unexplained. Here we develop a general mathematical model for the dynamics of mobile promoters, extending previous work to capture the dynamics both within and outside promoter regions. From this general model, we apply rigorous model selection techniques to identify which parameters are statistically justified in describing the available mobile promoter data, and find best-fit values of these parameters. Our results suggest that high rates of horizontal gene transfer maintain the population of mobile promoters in promoter regions, and that once established at these sites, mobile promoters are rarely lost, but are commonly copied to other genomic regions. In contrast, mobile promoter copies in non-promoter regions are more numerous and more volatile, experiencing substantially higher rates of duplication, loss and diversification.

    Divergent transcription, in which reverse-oriented transcripts occur upstream of eukaryotic promoters in regions devoid of annotated genes, has been suggested to be a general property of active promoters. Here we show that the human basal RNA polymerase II transcriptional machinery and core promoter are inherently unidirectional, and that reverse-oriented transcripts originate from their own cognate reverse-directed core promoters. In vitro transcription analysis and mapping of nascent transcripts in cells revealed that sequences at reverse start sites are similar to those of their forward counterparts. The use of DNase I accessibility to define proximal promoter borders revealed that up to half of promoters are unidirectional and that unidirectional promoters are depleted at their upstream edges of reverse core promoter sequences and their associated chromatin features. Divergent transcription is thus not an inherent property of the transcription process, but rather the consequence of the presence of both forward- and reverse-directed core promoters. PMID:25639469

    2009-05-01

    We report on the development of a software tool (PROMOTIONS) to streamline the process of measuring proper motions of material in expanding nebulae. Our tool makes use of IDL's widget programming capabilities to design a unique GUI that is used to compare images of the objects from two epochs. The software allows us to first orient and register the images to a common frame of reference and pixel scale, using field stars in each of the images. We then cross-correlate specific morphological features in order to determine their proper motions, which consist of the proper motion of the nebula as a whole (PM-neb), and expansion motions of the features relative to the center. If the central star is not visible (quite common in bipolar nebulae with dense dusty waists), point-symmetric expansion is assumed and we use the average motion of high-quality symmetric pairs of features on opposite sides of the nebular center to compute PM-neb. This is then subtracted out to determine the individual movements of these and additional features relative to the nebular center. PROMOTIONS should find wide applicability in measuring proper motions in astrophysical objects such as the expanding outflows/jets commonly seen around young and dying stars. We present first results from using PROMOTIONS to successfully measure proper motions in several pre-planetary nebulae (transition objects between the red giant and planetary nebula phases), using images taken 7-10 years apart with the WFPC2 and ACS instruments on board HST. The authors are grateful to NASA's Undergradute Scholars Research Program (USRP) for supporting this research.

    Nurses are accustomed to helping others with their sleep problems and dealing with issues such as pain that may delay or interrupt sleep. However, they may be less familiar with what constitutes a healthy night's sleep. This article examines what is known about the process and purpose of sleep, and examines the ways in which factors that promote wakefulness and sleep combine to help establish a normal circadian rhythm. Theories relating to the function of sleep are discussed and research is considered that suggests that sleep deficit may lead to metabolic risks, including heart disease, obesity, type 2 diabetes mellitus and several types of cancer.

  8. Targeted manipulation of leaf form via local growth repression.

    PubMed

    Malinowski, Robert; Kasprzewska, Ania; Fleming, Andrew J

    2011-06-01

    A classical view is that leaf shape is the result of local promotion of growth linked to cell proliferation. However, an alternative hypothesis is that leaf form is the result of local repression of growth in an otherwise growing system. Here we show that leaf form can indeed be manipulated in a directed fashion by local repression of growth. We show that targeting expression of an inhibitor of a cyclin-dependent kinase (KRP1) to the sinus area of developing leaves of Arabidopsis leads to local growth repression and the formation of organs with extreme lobing, including generation of leaflet-like organs. Directing KRP1 expression to other regions of the leaf using an miRNA target sequence tagging approach also leads to predictable novel leaf forms, and repression of growth in the leaf margin blocks the outgrowth of lobes, leading to a smoother perimeter. In addition, we show that decreased growth around the perimeter and across the leaf abaxial surface leads to a change in 3D form, as predicted by mechanical models of leaf growth. Our analysis provides experimental evidence that local repression of growth influences leaf shape, suggesting that it could be part of the mechanism of morphogenesis in plants in the context of an otherwise growing system.

    Peritoneal dialysis (PD) is complicated by peritonitis episodes that cause loss of mesothelium and eventually sclerosing peritonitis. An improved understanding of the molecular contributors to peritoneal injury and defense may increase the therapeutic armamentarium to optimize peritoneal defenses while minimizing peritoneal injury. There is no information on the expression and function of the cytokine TWEAK and its receptor Fn14 during peritoneal injury. Fn14 expression and soluble TWEAK levels were measured in human PD peritoneal effluent cells or fluids with or without peritonitis. Fn14 expression was also analyzed in peritoneal biopsies from PD patients. Actions of intraperitoneal TWEAK were studied in mice in vivo. sTWEAK levels were increased in peritoneal effluent in PD peritonitis. Effluent sTWEAK levels correlated with the number of peritoneal macrophages (r = 0.491, p = 0.002). Potential TWEAK targets that express the receptor Fn14 include mesothelial cells and macrophages, as demonstrated by flow cytometry of peritoneal effluents and by analysis of peritoneal biopsies. Peritoneal biopsy Fn14 correlated with mesothelial injury, fibrosis and inflammation, suggesting a potential deleterious effect of TWEAK/Fn14. In this regard, intraperitoneal TWEAK administration to mice promoted peritoneal inflammation characterized by increased peritoneal effluent MCP-1, Fn14 and Gr1+ macrophages, increased mesothelial Fn14, MCP-1 and CCL21 expression and submesothelial tissue macrophage recruitment. Taken together these data suggest that the TWEAK/Fn14 system may promote inflammation and tissue injury during peritonitis and PD. PMID:24599047

  11. Leptin Promotes Glioblastoma

    PubMed Central

    Lawrence, Johnathan E.; Cook, Nicholas J.; Rovin, Richard A.; Winn, Robert J.

    2012-01-01

    The hormone leptin has a variety of functions. Originally known for its role in satiety and weight loss, leptin more recently has been shown to augment tumor growth in a variety of cancers. Within gliomas, there is a correlation between tumor grade and tumor expression of leptin and its receptor. This suggests that autocrine signaling within the tumor microenvironment may promote the growth of high-grade gliomas. Leptin does this through stimulation of cellular pathways that are also advantageous for tumor growth and recurrence: antiapoptosis, proliferation, angiogenesis, and migration. Conversely, a loss of leptin expression attenuates tumor growth. In animal models of colon cancer and melanoma, a decline in the expression and secretion of leptin resulted in a reduction of tumor growth. In these models, positive mental stimulation through environmental enrichment decreased leptin secretion and improved tumor outcome. This review explores the link between leptin and glioblastoma.

    PubMed

    Esch, Tobias; Stefano, George B

    2005-06-01

    Love has consequences for health and well-being. Engaging in joyful activities such as love may activate areas in the brain responsible for emotion, attention, motivation and memory (i.e., limbic structures), and it may further serve to control the autonomic nervous system, i.e., stress reduction. This specific CNS activity pattern appears to exert protective effects, even on the brain itself. Moreover, anxiolytic effects of pleasurable experiences may occur by promotion of an inhibitory tone in specific areas of the brain. Thus, love and pleasure clearly are capable of stimulating health, well-being and (re)productivity: This wonderful biological instrument makes procreation and maintenance of organisms and their species a deeply rewarding and pleasurable experience, thus ensuring survival, health, and perpetuation.

    Catalytic steam reforming of methane for hydrogen production proceeds even at 473 K over 1 wt% Pd/CeO2 catalyst in an electric field, thanks to the surface protonics. Kinetic analyses demonstrated the synergetic effect between catalytic reaction and electric field, revealing strengthened water pressure dependence of the reaction rate when applying an electric field, with one-third the apparent activation energy at the lower reaction temperature range. Operando–IR measurements revealed that proton conduction via adsorbed water on the catalyst surface occurred during electric field application. Methane was activated by proton collision at the Pd–CeO2 interface, based on the inverse kinetic isotope effect. Proton conduction on the catalyst surface plays an important role in methane activation at low temperature. This report is the first describing promotion of the catalytic reaction by surface protonics.

    PubMed

    Hawkes, Corinna

    2009-06-01

    Sales promotions are widely used to market food to adults, children, and youth. Yet, in contrast to advertising, practically no attention has been paid to their impacts on dietary behaviors, or to how they may be used more effectively to promote healthy eating. This review explores the available literature on the subject. The objective is to identify if and what literature exists, examine the nature of this literature, and analyze what can be learned from it about the effects of sales promotions on food consumption. The review finds that while sales promotions lead to significant sales increases over the short-term, this does not necessarily lead to changes in food-consumption patterns. Nevertheless, there is evidence from econometric modeling studies indicating that sales promotions can influence consumption patterns by influencing the purchasing choices of consumers and encouraging them to eat more. These effects depend on the characteristics of the food product, sales promotion, and consumer. The complexity of the effects means that sales promotions aiming to encourage consumption of nutritious foods need to be carefully designed. These conclusions are based on studies that use mainly sales data as a proxy for dietary intake. The nutrition (and economics) research communities should add to this existing body of research to provide evidence on the impact of sales promotions on dietary intake and related behaviors. This would help support the development of a sales promotion environment conducive to healthy eating.

    2005-01-01

    Schools provide an important setting for promoting health, as they reach over 1 billion children worldwide and, through them, the school staff, families and the community as a whole. Health promotion messages can be reinforced throughout the most influential stages of children's lives, enabling them to develop lifelong sustainable attitudes and skills. Poor oral health can have a detrimental effect on children's quality of life, their performance at school and their success in later life. This paper examines the global need for promoting oral health through schools. The WHO Global School Health Initiative and the potential for setting up oral health programmes in schools using the health-promoting school framework are discussed. The challenges faced in promoting oral health in schools in both developed and developing countries are highlighted. The importance of using a validated framework and appropriate methodologies for the evaluation of school oral health projects is emphasized. PMID:16211159

  9. Information technology in health promotion.

    PubMed

    Lintonen, T P; Konu, A I; Seedhouse, D

    2008-06-01

    eHealth, the use of information technology to improve or enable health and health care, has recently been high on the health care development agenda. Given the vivid interest in eHealth, little reference has been made to the use of these technologies in the promotion of health. The aim of this present study was to conduct a review on recent uses of information technology in health promotion through looking at research articles published in peer-reviewed journals. Fifteen relevant journals with issues published between 2003 and June 2005 yielded altogether 1352 articles, 56 of which contained content related to the use of information technology in the context of health promotion. As reflected by this rather small proportion, research on the role of information technology is only starting to emerge. Four broad thematic application areas within health promotion were identified: use of information technology as an intervention medium, use of information technology as a research focus, use of information technology as a research instrument and use of information technology for professional development. In line with this rather instrumental focus, the concepts 'ePromotion of Health' or 'Health ePromotion' would come close to describing the role of information technology in health promotion.

  10. Health promotion: an ethical analysis.

    PubMed

    Carter, Stacy M

    2014-04-01

    Thinking and practising ethically requires reasoning systematically about the right thing to do. Health promotion ethics - a form of applied ethics - includes analysis of health promotion practice and how this can be ethically justified. Existing frameworks can assist in such evaluation. These acknowledge the moral value of delivering benefits. But benefits need to be weighed against burdens, harms or wrongs, and these should be minimised: they include invading privacy, breaking confidentiality, restraining liberty, undermining self-determination or people's own values, or perpetuating injustice. Thinking about the ethics of health promotion also means recognising health promotion as a normative ideal: a vision of the good society. This ideal society values health, sees citizens as active and includes them in decisions that affect them, and makes the state responsible for providing all of its citizens, no matter how advantaged or disadvantaged, with the conditions and resources they need to be healthy. Ethicists writing about health promotion have focused on this relationship between the citizen and the state. Comparing existing frameworks, theories and the expressed values of practitioners themselves, we can see common patterns. All oppose pursuing an instrumental, individualistic, health-at-all-costs vision of health promotion. And all defend the moral significance of just processes: those that engage with citizens in a transparent, inclusive and open way. In recent years, some Australian governments have sought to delegitimise health promotion, defining it as extraneous to the role of the state. Good evidence is not enough to counter this trend, because it is founded in competing visions of a good society. For this reason, the most pressing agenda for health promotion ethics is to engage with communities, in a procedurally just way, about the role and responsibilities of the citizen and the state in promoting and maintaining good health.

  12. Zoning should promote public health.

    PubMed

    Hirschhorn, Joel S

    2004-01-01

    Legally, governments use their police powers to protect public health, safety, and welfare through zoning. This paper presents a case for revisiting zoning on the basis of increasing evidence that certain types of community design promote public health, as opposed to the dominant pattern of sprawl development, which does not. Zoning, and the land use planning linked to it, that prohibits or disfavors health-promoting community designs contradicts the inherent public policy goal on which it is based. If there is a paradigm shift underway, from traditional sprawl to health-promoting community designs, then health professionals and others should understand why zoning must be reassessed.

    2017-02-17

    The World Health Organization states that health promotion is a key strategy to improve health, and it is conceived as a global process of enabling people to increase control over, and to improve, their health. Health promotion does not focus solely on empowering individuals dealing with their knowledge, attitudes and skills, but it also takes political, social, economic and environmental aspects influencing health and wellbeing into account. The complexity of applying these concepts is reflected in the five paradoxes in health promotion; these arise in between the rhetoric in health promotion and implementation. The detected paradoxes which are described herein involve the patient versus the person, the individual versus the group, disease professionals versus health professionals, disease indicators versus health indicators, and health as an expense versus health as an investment. Making these contradictions explicit can help determine why it is so complex to put the concepts related to health promotion into practice. It can also help to put forward aspects that need further work if health promotion is to put into practice.

  3. DNA signals at isoform promoters

    PubMed Central

    Dai, Zhiming; Xiong, Yuanyan; Dai, Xianhua

    2016-01-01

    Transcriptional heterogeneity is extensive in the genome, and most genes express variable transcript isoforms. However, whether variable transcript isoforms of one gene are regulated by common promoter elements remain to be elucidated. Here, we investigated whether isoform promoters of one gene have separated DNA signals for transcription and translation initiation. We found that TATA box and nucleosome-disfavored DNA sequences are prevalent in distinct transcript isoform promoters of one gene. These DNA signals are conserved among species. Transcript isoform has a RNA-determined unstructured region around its start site. We found that these DNA/RNA features facilitate isoform transcription and translation. These results suggest a DNA-encoded mechanism by which transcript isoform is generated. PMID:27353836

    Park, Jong Y.

    2011-01-01

    Background The prostate gland is the most common site of cancer and the second leading cause of cancer mortality in American men. It is well known that epigenetic alterations such as DNA methylation within the regulatory (promoter) regions of genes are associated with transcriptional silencing in cancer. Promoter hypermethylation of critical pathway genes could be potential biomarkers and therapeutic targets for prostate cancer. Methods This review discusses current information on methylated genes associated with prostate cancer development and progression. Results Over 30 genes have been investigated for promoter methylation in prostate cancer. These methylated genes are involved in critical pathways, such as DNA repair, metabolism, and invasion/metastasis. The role of hypermethylated genes in regulation of critical pathways in prostate cancer is reviewed. Conclusions These findings may provide new information of the pathogenesis of prostate cancer. Certain epigenetic alterations in prostate tumors are being translated into clinical practice for therapeutic use. PMID:20861812

  7. Promoting recovery from ischemic stroke.

    PubMed

    Schmidt, Antje; Minnerup, Jens

    2016-01-01

    Over recent decades, experimental and clinical stroke studies have identified a number of neurorestorative treatments that stimulate neural plasticity and promote functional recovery. In contrast to the acute stroke treatments thrombolysis and endovascular thrombectomy, neurorestorative treatments are still effective when initiated days after stroke onset, which makes them applicable to virtually all stroke patients. In this article, selected physical, pharmacological and cell-based neurorestorative therapies are discussed, with special emphasis on interventions that have already been transferred from the laboratory to the clinical setting. We explain molecular and structural processes that promote neural plasticity, discuss potential limitations of neurorestorative treatments, and offer a speculative viewpoint on how neurorestorative treatments will evolve.

  8. Synthetic Core Promoters for Pichia pastoris

    PubMed Central

    2013-01-01

    Synthetic promoters are commonly used tools for circuit design or high level protein production. Promoter engineering efforts in yeasts, such as Saccharomyces cerevisiae and Pichia pastoris have mostly been focused on altering upstream regulatory sequences such as transcription factor binding sites. In higher eukaryotes synthetic core promoters, directly needed for transcription initiation by RNA Polymerase II, have been successfully designed. Here we report the first synthetic yeast core promoter for P. pastoris, based on natural yeast core promoters. Furthermore we used this synthetic core promoter sequence to engineer the core promoter of the natural AOX1 promoter, thereby creating a set of core promoters providing a range of different expression levels. As opposed to engineering strategies of the significantly longer entire promoter, such short core promoters can directly be added on a PCR primer facilitating library generation and are sufficient to obtain variable expression yields.

    Hodges, Bonni C

    2017-03-01

    The arrival of a new summer collegiate baseball league franchise to a small central New York city was seen as an opportunity for health promotion. The initiative was set up to explore two overarching questions: (1) Are summer collegiate baseball events acceptable to local public health organizations as viable places for health promotion activities addressing local health issues? (2) Are summer collegiate baseball organizations amenable to health promotion activities built in to their fan and/or player experiences? Planning and implementation were guided by precede-proceed, social cognitive theory, social marketing, and diffusion of innovations constructs. Environmental changes were implemented to support healthy eating and nontobacco use by players and fans; four health awareness nights were implemented at home games corresponding to local public health priorities and included public service announcements, between inning quizzes, information dissemination at concession and team market locations, and special guests. Sales and fan feedback support mostly healthy concession offerings and a tobacco-free ballpark; postseason evaluations from team staff and public health partners support continuing the trials of this sports event as a venue for health promotion.

  6. Plant-growth-promoting rhizobacteria.

    PubMed

    Lugtenberg, Ben; Kamilova, Faina

    2009-01-01

    Several microbes promote plant growth, and many microbial products that stimulate plant growth have been marketed. In this review we restrict ourselves to bacteria that are derived from and exert this effect on the root. Such bacteria are generally designated as PGPR (plant-growth-promoting rhizobacteria). The beneficial effects of these rhizobacteria on plant growth can be direct or indirect. This review begins with describing the conditions under which bacteria live in the rhizosphere. To exert their beneficial effects, bacteria usually must colonize the root surface efficiently. Therefore, bacterial traits required for root colonization are subsequently described. Finally, several mechanisms by which microbes can act beneficially on plant growth are described. Examples of direct plant growth promotion that are discussed include (a) biofertilization, (b) stimulation of root growth, (c) rhizoremediation, and (d) plant stress control. Mechanisms of biological control by which rhizobacteria can promote plant growth indirectly, i.e., by reducing the level of disease, include antibiosis, induction of systemic resistance, and competition for nutrients and niches.

  2. Electrochemical promotion of catalytic reactions

    NASA Astrophysics Data System (ADS)

    Imbihl, R.

    2010-05-01

    The electrochemical promotion of heterogeneously catalyzed reactions (EPOC) became feasible through the use of porous metal electrodes interfaced to a solid electrolyte. With the O 2- conducting yttrium stabilized zirconia (YSZ), the Na + conducting β″-Al 2O 3 (β-alumina), and several other types of solid electrolytes the EPOC effect has been demonstrated for about 100 reaction systems in studies conducted mainly in the mbar range. Surface science investigations showed that the physical basis for the EPOC effect lies in the electrochemically induced spillover of oxygen and alkali metal, respectively, onto the surface of the metal electrodes. For the catalytic promotion effect general concepts and mechanistic schemes were proposed but these concepts and schemes are largely speculative. Applying surface analytical tools to EPOC systems the proposed mechanistic schemes can be verified or invalidated. This report summarizes the progress which has been achieved in the mechanistic understanding of the EPOC effect.

  3. [Empowerment and health promotion programming].

    PubMed

    Laverack, G

    2008-12-01

    Health promotion often presents a tension between "bottom up" and "top down" programming. "Bottom-up" is associated with community empowerment and begins on issues of concern to particular groups or individuals and regards an increase in overall control as an important element of the health outcome. "Top-down" is associated with disease prevention efforts and begins by seeking to involve beneficiaries on issues defined by health agencies. It regards improvements in health behaviours or bio-medical indicators as the important outcome and community empowerment is viewed simply as a means to the end of health behaviour change. The tension between these two approaches is not unresolvable, and this article presents a framework, the "parallel-track", intended to assist health promotion practitioners to systematically accommodate community empowerment goals within "top-down" health programming.

  4. Promoting the exotic pet practice.

    PubMed

    Harris, Don J

    2005-09-01

    The marketing and promotion of an exotic pet veterinary practice allows the use of strategies that are not necessarily available in other veterinary disciplines. The advantage that an exotics practice enjoys is that it is able to capitalize not only on the unique nature of the species being attended but also on the specialized features of the hospital itself that make it specifically appropriate in caring for exotic pets. Before marketing, however, comes the responsibility that the practice live up to the claims made in promotional materials. A practice cannot ethically be presented as an "exotics" practice if it is nothing more than a dog and cat facility that is willing to attend to exotic pets. It is the competence of the veterinary staff and the appropriateness of the facility that determines the suitability of the practice for exotics management.

  5. Drugs that promote dental caries.

    PubMed

    2015-02-01

    Dental caries result from erosion of tooth enamel or cementum by acidic substances produced by bacteria found in dental plaque. Caries can lead to pulp necrosis and tooth loss. Risk factors include certain dietary habits, poor oral hygiene, and dry mouth. Diabetes and Sjogren's syndrome can also promote dental caries. Psychotropic substances such as cocaine, methamphetamine, heroin and cannabis can promote dental caries. Many medicinal drugs facilitate the formation of dental caries, through various mechanisms; they include formulations with a high sugar content; drugs that cause dry mouth (especially antimuscarinics); drugs that lower the buccal pH (inhaled powders, etc.); and drugs that cause demineralisation (tetracyclines, etc.). In practice, patients (and parents) should be informed that some drugs can increase the risk of dental caries. They should be encouraged to adapt and reinforce dental hygiene, and advised to visit a dentist regularly.

  6. South Asia's health promotion kaleidoscope.

    PubMed

    Mukhopadhyay, Alok

    2007-01-01

    South Asia has 22 percent of the world's population but only 1.3 percent of the global income. Consequently 40 percent of the population is living in absolute poverty. However the health transition in some of its countries including India and Sri Lanka is a testimony to the fact that there are proven solutions to the problems of health and development within the region. The countries of the region have much in common, including a democratic political system, four major religions, a vibrant and living tradition of voluntarism and an extensive health infrastructure which is operating well below par. Despite the underlying unity, South Asia enjoys enormous cultural, linguistic and ethnic diversity. In this large, complex and vibrant region, health promotion is a challenging task, but it also holds the key to a dramatic change in the global health situation. Many of these solutions lie in wider areas of socio-political action. There are much needed shifts in the health promotion and development efforts, particularly in the area of poverty and social justice; gender inequity; population stabilisation; health and environment; control of communicable and non-communicable diseases; and urban health strategies. The principle of cooperation, partnership and intersectoral collaboration for health will be explored. Developing an appropriate, sustainable and people centred health and development strategy in the coming decades is an enormous challenge. There has been an attempt to focus on the emerging needs of the region, which call for health promotion, and involvement of civil society, private sector and the governments bestowed with the increased responsibility of ensuring health security for people. Strengthening the existing health systems, allocating adequate resources for health development and ensuring community participation are all prerequisites to the success of health promotion in the region.

  7. PARP promoter-mediated activation of a VSG expression site promoter in insect form Trypanosoma brucei.

    PubMed

    Urményi, T P; Van der Ploeg, L H

    1995-03-25

    In trypanosomes the rRNA, PARP and VSG gene promoters mediate alpha-amanitin-resistant transcription of protein coding genes, presumably by RNA polymerase (pol) I. We compared the activity of PARP and VSG promoters integrated at one of the alleles of the largest subunit of pol II genes in insect form trypanosomes. Even though both promoters are roughly equally active in transient transformation assays in insect form trypanosomes, only the PARP promoter functioned effectively when integrated at the pol II largest subunit or other loci. Promoter activity in transient transformation assays is therefore not necessarily predictive of transcriptional activity once integrated into the trypanosome genome. The integrated fully active PARP promoter could upregulate in cis an otherwise poorly active integrated VSG promoter. The PARP promoter nucleotide sequence elements responsible for VSG promoter activation coincided with most of the important PARP promoter elements mapped previously by linker scanning mutagenesis, indicating that it is not a single unique promoter element that was responsible for VSG promoter activation. The data suggest that PARP promoter-mediated activation of the VSG promoter does not result from complementation of the VSG promoter with a single insect form-specific transcription factor whose binding site is missing from the VSG promoter and present in the PARP promoter. We favor a model in which chromatin structure at the locus is altered by the PARP promoter, allowing VSG promoter activation in insect form trypanosomes. We discuss the significance of these observations for the control of VSG promoters in insect form trypanosomes.

  8. Physical characteristics in eucaryotic promoters.

    PubMed Central

    Bensimhon, M; Gabarro-Arpa, J; Ehrlich, R; Reiss, C

    1983-01-01

    For a series of wild type and mutated eucaryotic gene prelude sequences (mainly "promoters" of SV40 early gene (Benoist and Chambon, Nature 290, 304 (1981); Moreau et al., Nuc. Acids Res. 9, 6047 (1982)) and of Herpes Simplex Virus TK gene (McKnight and Kingsbury, Science 217, 316 (1982)), in vivo promoter activity and local stability (denaturability) have been correlated. In agreement with the conclusions drawn in these papers, the correlation points to three major eucaryotic promoter elements and loci: (i) enzyme enabling by an enhancer sequence; SV40 and Moloney Sarcoma Virus enhancers have a striking stability homology; (ii) enzyme activation, occurring 50-70 b.p. upstream the cap site in a high stability domain; the enzyme apparently deactivates exponentially upon moving away to trap site; (iii) enzyme positioning at trap site, 30 +/- 5 b.p. upstream the cap site. The trap site contains the TATA box, or, when absent, other low stability domains downstream the activator. The number and occupancy of cap sites may depend on the stability and size of the trap site-cap site couple and its distance from the activator. PMID:6306592

  9. Incentives to promote family planning

    PubMed Central

    Heil, Sarah H.; Gaalema, Diann E.; Herrmann, Evan S.

    2012-01-01

    Objective Over the past 60 years, population control has become an increasingly urgent issue worldwide as a growing population strains already limited resources. The use of financial incentives to promote family planning is an innovative approach that has potential to make a contribution to efforts to better manage population growth. This report reviews eight studies that examined the effect of incentives on family planning. Method Published studies that tested the impact of incentives to promote some aspect of family planning and included an appropriate control or comparison condition were reviewed. Results Incentives have been used to promote attendance at contraceptive education sessions, adoption and continuation of contraceptive methods, sterilization, and to limit family size. All but one of the eight studies reviewed reported positive outcomes, but weaknesses in study design and execution limit the strength of the conclusions that can be drawn. Conclusion Review of this literature suggests that family planning behaviors, like other behaviors, are sensitive to incentives. Given the tremendous need for efficacious interventions in global efforts to manage population growth, further research on this topic using more rigorous experimental methods is warranted.

  10. Programming gene expression with combinatorial promoters

    PubMed Central

    Cox, Robert Sidney; Surette, Michael G; Elowitz, Michael B

    2007-01-01

    Promoters control the expression of genes in response to one or more transcription factors (TFs). The architecture of a promoter is the arrangement and type of binding sites within it. To understand natural genetic circuits and to design promoters for synthetic biology, it is essential to understand the relationship between promoter function and architecture. We constructed a combinatorial library of random promoter architectures. We characterized 288 promoters in Escherichia coli, each containing up to three inputs from four different TFs. The library design allowed for multiple −10 and −35 boxes, and we observed varied promoter strength over five decades. To further analyze the functional repertoire, we defined a representation of promoter function in terms of regulatory range, logic type, and symmetry. Using these results, we identified heuristic rules for programming gene expression with combinatorial promoters. PMID:18004278

  11. Promotion to professor: a career development resource.

    PubMed

    Sanfey, Hilary

    2010-10-01

    By the time a faculty member is being considered for promotion to full professor, he/she will be about 10 years out of residency training and will almost certainly have prior experience with the academic promotion process. The preparation for promotion to full professor should begin soon after the promotion to associate professor. This is a time to reassess opportunities, resources, skills, and career goals. The timing of the promotion to full professor is usually less rigid than the timeframe for promotion at lower ranks, but schools vary in this regard.

  12. Natural selection promotes antigenic evolvability.

    PubMed

    Graves, Christopher J; Ros, Vera I D; Stevenson, Brian; Sniegowski, Paul D; Brisson, Dustin

    2013-01-01

    The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence. The antigenic variation mechanisms of microbial pathogens provide an experimentally tractable system to test whether natural selection has favored mechanisms that increase evolvability. Many antigenic variation systems consist of paralogous unexpressed 'cassettes' that recombine into an expression site to rapidly alter the expressed protein. Importantly, the magnitude of antigenic change is a function of the genetic diversity among the unexpressed cassettes. Thus, evidence that selection favors among-cassette diversity is direct evidence that natural selection promotes antigenic evolvability. We used the Lyme disease bacterium, Borrelia burgdorferi, as a model to test the prediction that natural selection favors amino acid diversity among unexpressed vls cassettes and thereby promotes evolvability in a primary surface antigen, VlsE. The hypothesis that diversity among vls cassettes is favored by natural selection was supported in each B. burgdorferi strain analyzed using both classical (dN/dS ratios) and Bayesian population genetic analyses of genetic sequence data. This hypothesis was also supported by the conservation of highly mutable tandem-repeat structures across B. burgdorferi strains despite a near complete absence of sequence conservation. Diversification among vls cassettes due to natural selection and mutable repeat structures promotes long-term antigenic evolvability of VlsE. These findings provide a direct demonstration that molecular mechanisms that enhance evolvability of surface antigens are an evolutionary adaptation. The molecular evolutionary processes identified here can serve as a model for the evolution of antigenic evolvability in many pathogens which utilize similar strategies to establish chronic infections.

  13. Immune cell promotion of metastasis

    PubMed Central

    Kitamura, Takanori; Qian, Bin-Zhi; Pollard, Jeffrey W.

    2015-01-01

    Metastatic disease is the major cause of death from cancer, and immunotherapy and chemotherapy have had limited success in reversing its progression. Data from mouse models suggest that the recruitment of immunosuppressive cells to tumours protects metastatic cancer cells from surveillance by killer cells, which nullifies the effects of immunotherapy and thus establishes metastasis. Furthermore, in most cases, tumour-infiltrating immune cells differentiate into cells that promote each step of the metastatic cascade and thus are novel targets for therapy. In this Review, we describe how tumour-infiltrating immune cells contribute to the metastatic cascade and we discuss potential therapeutic strategies to target these cells. PMID:25614318

    PubMed

    Tseng, Vivian; Chesir-Teran, Daniel; Becker-Klein, Rachel; Chan, May L; Duran, Valkiria; Roberts, Ann; Bardoliwalla, Nenshad

    2002-06-01

    This paper argues for the need to advance promotion efforts and proposes a conceptual framework for promotion of social change. A brief review is presented of traditional frameworks for the prevention of mental and social disorders and the promotion of wellness and social competencies, with attention to the ways in which promotion of social change extends and departs from these frameworks. In a framework for promoting social change, we advocate for promoting dynamic processes within systems, rather than outcomes within individuals. Systems are viewed as flexible and capable of facilitating multiple adaptive pathways for individuals and groups. Promoting social change also involves careful attention to critical analysis, values, language, and contextual processes. Examples are discussed throughout to illustrate how these principles have been used in the past and can be implemented in future efforts to promote social change.

  7. Disease Prevention and Health Promotion

    PubMed Central

    Ali, Ather; Katz, David L.

    2015-01-01

    As a discipline, preventive medicine has traditionally been described to encompass primary, secondary, and tertiary prevention. The fields of preventive medicine and public health share the objectives of promoting general health, preventing disease, and applying epidemiologic techniques to these goals. This paper discusses a conceptual approach between the overlap and potential synergies of integrative medicine principles and practices with preventive medicine in the context of these levels of prevention, acknowledging the relative deficiency of research on the effectiveness of practice-based integrative care. One goal of integrative medicine is to make the widest array of appropriate options available to patients, ultimately blurring the boundaries between conventional and complementary medicine. Both disciplines should be subject to rigorous scientific inquiry so that interventions that are efficacious and effective are systematically distinguished from those that are not. Furthermore, principles of preventive medicine can be infused into prevalent practices in complementary and integrative medicine, promoting public health in the context of more-responsible practices. The case is made that an integrative preventive approach involves the responsible use of science with responsiveness to the needs of patients that persist when conclusive data are exhausted, providing a framework to make clinical decisions among integrative therapies.

  8. Condom ads promote illicit sex.

    PubMed

    Kippley, J F

    1994-01-01

    Written in 1987, this opinion was republished in the wake of US President Bill Clinton's AIDS prevention media campaign promoting condom use which began January 1994, targeted at young adults aged 18-25. The author staunchly opposes condom use even though he admits that people do not consider abstinence from sex to be a serious option for the prevention of HIV/STD infection. He believes that there is no moral use of sex with a condom and that condoms have always been a sign of immorality, be it prostitution, adultery, fornication, or marital contraception. Likewise, the author laments the success enjoyed by Planned Parenthood in achieving the social acceptance of marital contraception and sex outside of marriage. The complete social acceptance of homosexual activity, however, remains to be achieved. Magazines, newspapers, and television receive income in exchange for publishing or airing advertisements. Finding offensive advertisements which promote the use of condoms against HIV infection, the author recommends writing letters of complaint to the responsible media sources. If the television stations or publications in question continue to advertise condoms to the public, stop watching them or end one's subscriptions to the particular printed media. Such action taken collectively among many individuals will reduce product sales and income, and potentially sway corporate policy against condom ads.

  9. Synthetic promoter design for new microbial chassis

    PubMed Central

    Gilman, James; Love, John

    2016-01-01

    The judicious choice of promoter to drive gene expression remains one of the most important considerations for synthetic biology applications. Constitutive promoter sequences isolated from nature are often used in laboratory settings or small-scale commercial production streams, but unconventional microbial chassis for new synthetic biology applications require well-characterized, robust and orthogonal promoters. This review provides an overview of the opportunities and challenges for synthetic promoter discovery and design, including molecular methodologies, such as saturation mutagenesis of flanking regions and mutagenesis by error-prone PCR, as well as the less familiar use of computational and statistical analyses for de novo promoter design.

  10. Towards a relational health promotion.

    PubMed

    Veenstra, Gerry; Burnett, Patrick John

    2016-03-01

    The Ottawa Charter for Health Promotion exhibits a substantialist approach to the agency-structure dichotomy. From a substantialist point of view, both individual agency and social structure come preformed and subsequently relate to and influence one another, starkly positioning the choices made by individuals against the structured sets of opportunities and constraints in reference to which choices are made. From a relational perspective, however, relations between elements, not the elements themselves, are the primary ontological focus. We advocate for a relational approach to the structure-agency dichotomy, one that locates both agency and structure in social relations and thereby dissolves the stark distinction between them, suggesting that relational theories can provide useful insights into how and why people 'choose' to engage in health-related behaviours. Pierre Bourdieu's theory of practice, predicated upon the notions of field, capital and habitus, is exemplary in this regard.

  11. Promoting Teen Mothers' Mental Health.

    PubMed

    Freed, Patricia; SmithBattle, Lee

    2016-01-01

    In this second article in a two-part series, we call for the integration of strengths-based and trauma-informed care into services for teen mothers. Nurses working with teen mothers in health clinics, schools and home visiting programs can play a pivotal role in promoting their mental health. Many teen mothers have high levels of psychological distress and histories of adverse experiences that cannot be ignored, and cannot solely be addressed by referral to mental health services. Nurses must be prepared to assess for trauma and be open to listening to teen mothers' experiences. Principles of strengths-based and trauma-informed care are complementary and can be integrated in clinical services so that teen mothers' distress is addressed and their strengths and aspirations are supported. Potential screening tools, interviewing skills and basic strategies to alleviate teen mothers' distress are discussed.

  12. Promoter usage and alternative splicing.

    PubMed

    Kornblihtt, Alberto R

    2005-06-01

    Recent findings justify a renewed interest in alternative splicing (AS): the process is more a rule than an exception as it affects the expression of 60% of human genes; it explains how a vast mammalian proteomic complexity is achieved with a limited number of genes; and mutations in AS regulatory sequences are a widespread source of human disease. AS regulation not only depends on the interaction of splicing factors with their target sequences in the pre-mRNA but is coupled to transcription. A clearer picture is emerging of the mechanisms by which transcription affects AS through promoter identity and occupation. These mechanisms involve the recruitment of factors with dual functions in transcription and splicing (i.e. that contain both functional domains and hence link the two processes) and the control of RNA polymerase II elongation.

    2001-01-01

    Despite the tobacco industry's claims that it has changed its practices, the toll of tobacco-related disease and death continues to grow worldwide, and the industry continues to use a vast array of strategies to promote its products and increase profits. This commentary discusses the ways the tobacco industry has created controversy about risk assessment and about the scientific evidence of the health hazards of secondhand smoke. The authors recommend that policymakers be more vigilant and that they demand transparency about affiliations and linkages between allegedly independent scientists and tobacco companies. They also urge policymakers to be prepared for new and continuing challenges posed by the tobacco industry, because, despite the industry's claims, there is little evidence of fundamental change in its objectives.

  14. Vessel Noise Promotes Hull Fouling.

    PubMed

    Stanley, Jenni A; Wilkens, Serena; McDonald, Justin I; Jeffs, Andrew G

    2016-01-01

    Fouling of submerged vessel hulls due to the rapid settlement of algae and invertebrates is a longstanding and costly problem. It is widely thought that the presence of extensive vacant surfaces on vessel hulls is responsible for the rapid attachment and growth of biofouling. We investigated whether noise from vessels in port could also be involved in promoting the settlement and growth of common biofouling organisms on vessel hulls. Three important biofouling species exhibited significantly faster development and settlement and better survival when exposed to vessel noise compared with control species. The extent of these responses appeared to vary in relation to the intensity of the vessel noise and may help to explain differences in biofouling observed on vessel hulls.

    Stress granules (SGs) harbour translationally stalled messenger ribonucleoproteins and play important roles in regulating gene expression and cell fate. Here we show that neddylation promotes SG assembly in response to arsenite-induced oxidative stress. Inhibition or depletion of key components of the neddylation machinery concomitantly inhibits stress-induced polysome disassembly and SG assembly. Affinity purification and subsequent mass-spectrometric analysis of Nedd8-conjugated proteins from translationally stalled ribosomal fractions identified ribosomal proteins, translation factors and RNA-binding proteins (RBPs), including SRSF3, a previously known SG regulator. We show that SRSF3 is selectively neddylated at Lys85 in response to arsenite. A non-neddylatable SRSF3 (K85R) mutant do not prevent arsenite-induced polysome disassembly, but fails to support the SG assembly, suggesting that the neddylation pathway plays an important role in SG assembly.

  16. Preconception care: promoting reproductive planning

    PubMed Central

    2014-01-01

    Introduction Preconception care recognizes that many adolescent girls and young women will be thrust into motherhood without the knowledge, skills or support they need. Sixty million adolescents give birth each year worldwide, even though pregnancy in adolescence has mortality rates at least twice as high as pregnancy in women aged 20-29 years. Reproductive planning and contraceptive use can prevent unintended pregnancies, unsafe abortions and sexually-transmitted infections in adolescent girls and women. Smaller families also mean better nutrition and development opportunities, yet 222 million couples continue to lack access to modern contraception. Method A systematic review and meta-analysis of the evidence was conducted to ascertain the possible impact of preconception care for adolescents, women and couples of reproductive age on MNCH outcomes. A comprehensive strategy was used to search electronic reference libraries, and both observational and clinical controlled trials were included. Cross-referencing and a separate search strategy for each preconception risk and intervention ensured wider study capture. Results Comprehensive interventions can prevent first pregnancy in adolescence by 15% and repeat adolescent pregnancy by 37%. Such interventions should address underlying social and community factors, include sexual and reproductive health services, contraceptive provision; personal development programs and emphasizes completion of education. Appropriate birth spacing (18-24 months from birth to next pregnancy compared to short intervals <6 months) can significantly lower maternal mortality, preterm births, stillbirths, low birth weight and early neonatal deaths. Conclusion Improving adolescent health and preventing adolescent pregnancy; and promotion of birth spacing through increasing correct and consistent use of effective contraception are fundamental to preconception care. Promoting reproductive planning on a wider scale is closely interlinked with the

    Memory is constructive in nature so that it may sometimes lead to the retrieval of distorted or illusory information. Sleep facilitates accurate declarative memory consolidation but might also promote such memory distortions. We examined the influence of sleep and lack of sleep on the cerebral correlates of accurate and false recollections using fMRI. After encoding lists of semantically related word associates, half of the participants were allowed to sleep, whereas the others were totally sleep deprived on the first postencoding night. During a subsequent retest fMRI session taking place 3 days later, participants made recognition memory judgments about the previously studied associates, critical theme words (which had not been previously presented during encoding), and new words unrelated to the studied items. Sleep, relative to sleep deprivation, enhanced accurate and false recollections. No significant difference was observed in brain responses to false or illusory recollection between sleep and sleep deprivation conditions. However, after sleep but not after sleep deprivation (exclusive masking), accurate and illusory recollections were both associated with responses in the hippocampus and retrosplenial cortex. The data suggest that sleep does not selectively enhance illusory memories but rather tends to promote systems-level consolidation in hippocampo-neocortical circuits of memories subsequently associated with both accurate and illusory recollections. We further observed that during encoding, hippocampal responses were selectively larger for items subsequently accurately retrieved than for material leading to illusory memories. The data indicate that the early organization of memory during encoding is a major factor influencing subsequent production of accurate or false memories.

  18. Pmp27 promotes peroxisomal proliferation

    PubMed Central

    1995-01-01

    Peroxisomes perform many essential functions in eukaryotic cells. The weight of evidence indicates that these organelles divide by budding from preexisting peroxisomes. This process is not understood at the molecular level. Peroxisomal proliferation can be induced in Saccharomyces cerevisiae by oleate. This growth substrate is metabolized by peroxisomal enzymes. We have identified a protein, Pmp27, that promotes peroxisomal proliferation. This protein, previously termed Pmp24, was purified from peroxisomal membranes, and the corresponding gene, PMP27, was isolated and sequenced. Pmp27 shares sequence similarity with the Pmp30 family in Candida boidinii. Pmp27 is a hydrophobic peroxisomal membrane protein but it can be extracted by high pH, suggesting that it does not fully span the bilayer. Its expression is regulated by oleate. The function of Pmp27 was probed by observing the phenotype of strains in which the protein was eliminated by gene disruption or overproduced by expression from a multicopy plasmid. The strain containing the disruption (3B) was able to grow on all carbon sources tested, including oleate, although growth on oleate, glycerol, and acetate was slower than wild type. Strain 3B contained peroxisomes with all of the enzymes of beta-oxidation. However, in addition to the presence of a few modestly sized peroxisomes seen in a typical thin section of a cell growing on oleate-containing medium, cells of strain 3B also contained one or two very large peroxisomes. In contrast, cells in a strain in which Pmp27 was overexpressed contained an increased number of normal-sized peroxisomes. We suggest that Pmp27 promotes peroxisomal proliferation by participating in peroxisomal elongation or fission. PMID:7721939

  19. Single promoters as regulatory network motifs

    NASA Astrophysics Data System (ADS)

    Zopf, Christopher; Maheshri, Narendra

    2012-02-01

    At eukaryotic promoters, chromatin can influence the relationship between a gene's expression and transcription factor (TF) activity. This additional complexity might allow single promoters to exhibit dynamical behavior commonly attributed to regulatory motifs involving multiple genes. We investigate the role of promoter chromatin architecture in the kinetics of gene activation using a previously described set of promoter variants based on the phosphate-regulated PHO5 promoter in S. cerevisiae. Accurate quantitative measurement of transcription activation kinetics is facilitated by a controllable and observable TF input to a promoter of interest leading to an observable expression output in single cells. We find the particular architecture of these promoters can result in a significant delay in activation, filtering of noisy TF signals, and a memory of previous activation -- dynamical behaviors reminiscent of a feed-forward loop but only requiring a single promoter. We suggest this is a consequence of chromatin transactions at the promoter, likely passing through a long-lived ``primed'' state between its inactive and competent states. Finally, we show our experimental setup can be generalized as a ``gene oscilloscope'' to probe the kinetics of heterologous promoter architectures.

  20. Insights into the control of geminiviral promoters.

    PubMed

    Borah, B K; Zarreen, F; Baruah, G; Dasgupta, I

    2016-08-01

    Geminiviruses constitute one of the largest groups of plant viruses, having characteristic twinned geminate particles encapsidating small circular single-stranded DNA molecules. Geminiviral promoters are generally located within the intergenic region, although promoters have also been detected within the genes. Similarly, the geminivirus-associated betasatellite also harbours a promoter element for driving the expression of its only ORF. These regulatory elements of geminiviral and satellite origins have been subject of great interest to develop heterologous gene expression modules. Geminiviral promoter and regulatory elements show a complex regulation that is mediated by several host as well as viral proteins. Here, the structural and functional features of geminiviral and satellite promoters are discussed along with their regulation by plant and viral proteins. Although generalization in many cases is difficult and demands further studies, a pattern is seen to emerge on the regulation of the promoters.

    2012-09-01

    A role for hypercholesterolemia in the development of osteoporosis has been suggested in published reports. However, few studies contain direct evidence of a role for maintenance of cholesterol homeostasis in bone health. Using isocaloric high-fat/high-cholesterol and low-fat/no-cholesterol diets in a 4-month feeding study combined with micro computed tomography analysis, we demonstrated in two different mouse strains that mice with hypercholesterolemia lose cortical and trabecular bone in the femurs and vertebrae (bone mineral density was decreased on average by ≈90 mg/mL in the cortical vertebrae in one strain) and cortical bone in the calvariae (bone mineral density was decreased on average by ≈60 mg/mL in one strain). Mechanical testing of the femurs demonstrated that loss of bone in the mice with hypercholesterolemia caused changes in the mechanical properties of the bone including loss of failure load (failure load was decreased by ≈10 N in one strain) and energy to failure. Serologic and histomorphologic analyses suggested that hypercholesterolemia promotes osteoclastogenesis. These studies support a role for hypercholesterolemia in the development of osteoporosis and provide a model with which to test intervention strategies to reduce the effects of hypercholesterolemia on bone health.

    Well-characterized promoters are essential tools for metabolic engineering and synthetic biology. In Streptomyces coelicolor, the native kasOp is a temporally expressed promoter strictly controlled by two regulators, ScbR and ScbR2. In this work, first, kasOp was engineered to remove a common binding site of ScbR and ScbR2 upstream of its core region, thus generating a stronger promoter, kasOp3. Second, another ScbR binding site internal to the kasOp3 core promoter region was abolished by random mutation and screening of the mutant library to obtain the strongest promoter, kasOp* (where the asterisk is used to distinguish the engineered promoter from the native promoter). The activities of kasOp* were compared with those of two known strong promoters, ermEp* and SF14p, in three Streptomyces species. kasOp* showed the highest activity at the transcription and protein levels in all three hosts. Furthermore, relative to ermEp* and SF14p, kasOp* was shown to confer the highest actinorhodin production level when used to drive the expression of actII-ORF4 in S. coelicolor. Therefore, kasOp* is a simple and well-defined strong promoter useful for gene overexpression in streptomycetes.

    Well-characterized promoters are essential tools for metabolic engineering and synthetic biology. In Streptomyces coelicolor, the native kasOp is a temporally expressed promoter strictly controlled by two regulators, ScbR and ScbR2. In this work, first, kasOp was engineered to remove a common binding site of ScbR and ScbR2 upstream of its core region, thus generating a stronger promoter, kasOp3. Second, another ScbR binding site internal to the kasOp3 core promoter region was abolished by random mutation and screening of the mutant library to obtain the strongest promoter, kasOp* (where the asterisk is used to distinguish the engineered promoter from the native promoter). The activities of kasOp* were compared with those of two known strong promoters, ermEp* and SF14p, in three Streptomyces species. kasOp* showed the highest activity at the transcription and protein levels in all three hosts. Furthermore, relative to ermEp* and SF14p, kasOp* was shown to confer the highest actinorhodin production level when used to drive the expression of actII-ORF4 in S. coelicolor. Therefore, kasOp* is a simple and well-defined strong promoter useful for gene overexpression in streptomycetes. PMID:23686264

    This will most likely be the first time through the promotion and tenure process for the faculty member. The faculty member is responsible for meeting with the department chair and/or division chief on a regular basis to determine if she is on the right time line to successfully achieve promotion to associate professor. A physician will begin seriously preparing her portfolio for promotion to associate professor about 5 to 6 years out of training, at which time she will have some considerable experience running a practice and managing her time. However, the planning process for promotion should begin immediately upon starting the first academic position.

  8. WHO Health Promotion Glossary: new terms.

    Smith, Ben J; Tang, Kwok Cho; Nutbeam, Don

    2006-12-01

    The WHO Health Promotion Glossary was written to facilitate understanding, communication and cooperation among those engaged in health promotion at the local, regional, national and global levels. Two editions of the Glossary have been released, the first in 1986 and the second in 1998, and continued revision of the document is necessary to promote consensus regarding meanings and to take account of developments in thinking and practice. In this update 10 new terms that are to be included in the Glossary are presented. Criteria for the inclusion of terms in the Glossary are that they differentiate health promotion from other health concepts, or have a specific application or meaning when used in relation to health promotion. The terms defined here are: burden of disease; capacity building; evidence-based health promotion; global health; health impact assessment; needs assessment; self-efficacy; social marketing; sustainable health promotion strategies, and; wellness. WHO will continue to periodically update the Health Promotion Glossary to ensure its relevance to the international health promotion community.

  10. Promoting Strong Written Communication Skills

    The reason that an improvement in the quality of technical writing is still needed in the classroom is due to the fact that universities are facing challenging problems not only on the technological front but also on the socio-economic front. The universities are actively responding to the changes that are taking place in the global consumer marketplace. Obviously, there are numerous benefits of promoting strong written communication skills. They can be summarized into the following six categories. First, and perhaps the most important: The University achieves learner satisfaction. The learner has documented verbally, that the necessary knowledge has been successfully acquired. This results in learner loyalty that in turn will attract more qualified learners.Second, quality communication lowers the cost per pupil, consequently resulting in increased productivity backed by a stronger economic structure and forecast. Third, quality communications help to improve the cash flow and cash reserves of the university. Fourth, having high quality communication enables the university to justify the need for high costs of tuition and fees. Fifth, better quality in written communication skills result in attracting top-quality learners. This will lead to happier and satisfied learners, not to mention greater prosperity for the university as a whole. Sixth, quality written communication skills result in reduced complaints, thus meaning fewer hours spent on answering or correcting the situation. The University faculty and staff are thus able to devote more time on scholarly activities, meaningful research and productive community service. References Boyer, Ernest L. (1990).

  13. Linking Core Promoter Classes to Circadian Transcription

    PubMed Central

    Westermark, Pål O.

    2016-01-01

    Circadian rhythms in transcription are generated by rhythmic abundances and DNA binding activities of transcription factors. Propagation of rhythms to transcriptional initiation involves the core promoter, its chromatin state, and the basal transcription machinery. Here, I characterize core promoters and chromatin states of genes transcribed in a circadian manner in mouse liver and in Drosophila. It is shown that the core promoter is a critical determinant of circadian mRNA expression in both species. A distinct core promoter class, strong circadian promoters (SCPs), is identified in mouse liver but not Drosophila. SCPs are defined by specific core promoter features, and are shown to drive circadian transcriptional activities with both high averages and high amplitudes. Data analysis and mathematical modeling further provided evidence for rhythmic regulation of both polymerase II recruitment and pause release at SCPs. The analysis provides a comprehensive and systematic view of core promoters and their link to circadian mRNA expression in mouse and Drosophila, and thus reveals a crucial role for the core promoter in regulated, dynamic transcription.

    2010-03-01

    Regulation of the sumoylation system at the level of gene expression has not yet been explored. To begin to define transcriptional regulatory features, the promoter region for the SUMO1 gene was cloned from human genomic DNA and characterized. Initially, a 532 base pair fragment upstream of and including the predicted SUMO1 transcription start site (TSS) was cloned and shown to possess promoter activity. Subsequent deletion analysis showed that a smaller fragment containing 158 bp upstream of the TSS region exhibited basal promoter activity in both human and rodent cell lines. Within this basal promoter fragment, there were predicted binding sites for numerous transcription factors, including the nude mouse gene product, Whn (FoxN1). Electrophoretic mobility shift assays showed that Whn could bind to an ACGC motif adjacent to the TSR, and in transfection studies Whn stimulated a 3-fold increase in transcription from this cloned promoter in keratinocytes (HaCaT cells). Mutation of the ACGC motif abrogated both Whn binding and transcriptional activation, indicating that the Whn effect is likely due to direct interaction with this promoter element. Consistent with these observations on the cloned promoter region, Whn also modestly stimulated transcription from the endogenous, genomic SUMO1 promoter in HaCaT cells, consistent with Whn potentially playing a regulatory role for SUMO1 transcription in keratinocytes.

    1998-01-01

    Promoting health underlines the right of each individual to the highest attainable standard of health. It stresses the importance of the participation of people and recognizes different sociocultural values and beliefs that are prevalent throughout the world. Working on health development has a sustainable effect only when done comprehensively: personal development, community development, organizational development, and political development. The international conferences that have marked the way of health promotion have been goal posts of an energetic movement to strengthen health worldwide. The Ottawa Charter on Health Promotion has been a worldwide source of guidance for health promotion through its five strategies: building health policy, creating supportive elements, strengthening community action, developing personal skills, and reorienting health services. Moreover, the Jakarta Declaration on "Leading Health Promotion into the 21st Century" identifies five priorities in the next millennium: 1) promote social responsibility for health; 2) increase investments for health development; 3) consolidate and expand partnerships for health; 4) increase community capacity and empower the individual in matters of health; and 5) secure an infrastructure for health promotion. Increasing the investment in health development calls for the need to find new mechanisms for funding as well as reorienting existing resources towards health promotion and health education.

  18. How should vasectomy be promoted in Guatemala?

    PubMed

    Piotrow, P T; Kincaid, D L

    1988-01-01

    In the article "Evaluation of a Communications Program to Increase Adoption of Vasectomy in Guatemala" by J.T. Bertrand et al (Stud Fam Plann 1987 Nov/Dec), the authors conclude that the use of a male promoter alone was 4 times more cost-effective in increasing the number of vasectomies than the use of radio alone because the costs of the radio program were 4 times higher. This conclusion is questionable for several reasons. 1) The district where the promoter was used alone was twice as large as the radio-only district. 2) In one of the promoter-only districts the same promoter worked throughout the program, but in the other, 3 different promoters had to be recruited and trained, due to high personnel turnover. 3) The initial costs of a radio program may be higher, but 1 program can be broadcast in all districts with little or no extra cost, whereas the costs of a promoter would have to be multiplied by the number of districts. 4) Although the promoter and the radio program produced approximately equal numbers of vasectomies, the radio messages reached over 70% of the people surveyed. Thus, on a national basis, radio broadcasts would be far more cost-effective than the use of salaried promoters in each district.

    Tumor promotion is defined as 1 step of carcinogenesis. Its intervention occurred when cell DNA was already damaged by a carcinogen and is the support of quiescent mutations. This leads to a complete malignant transformation of the cells by a non genotoxic mechanism. The presence of tumor promoters in our environment, although difficult to estimate, must be taken into account. This requires further research.

  14. Composing a Tumor Specific Bacterial Promoter

    PubMed Central

    Deyneko, Igor V.; Kasnitz, Nadine; Leschner, Sara; Weiss, Siegfried

    2016-01-01

    Systemically applied Salmonella enterica spp. have been shown to invade and colonize neoplastic tissues where it retards the growth of many tumors. This offers the possibility to use the bacteria as a vehicle for the tumor specific delivery of therapeutic molecules. Specificity of such delivery is solely depending on promoter sequences that control the production of a target molecule. We have established the functional structure of bacterial promoters that are transcriptionally active exclusively in tumor tissues after systemic application. We observed that the specific transcriptional activation is accomplished by a combination of a weak basal promoter and a strong FNR binding site. This represents a minimal set of control elements required for such activation. In natural promoters, additional DNA remodeling elements are found that alter the level of transcription quantitatively. Inefficiency of the basal promoter ensures the absence of transcription outside tumors. As a proof of concept, we compiled an artificial promoter sequence from individual motifs representing FNR and basal promoter and showed specific activation in a tumor microenvironment. Our results open possibilities for the generation of promoters with an adjusted level of expression of target proteins in particular for applications in bacterial tumor therapy. PMID:27171245

  16. The double jeopardy of sales promotions.

    PubMed

    Jones, J P

    1990-01-01

    The maturing of most consumer markets in the United States has put great pressure on manufacturers in their search for growth. They have concentrated on building sales and expanding share proportions in the stagnant markets with devices like niche products, product extensions, mergers, and international ventures. They have shifted emphasis to sales promotions at the expense of advertising. But promotions, when you come right down to it, mean price reductions. Trade promotions are almost always rebates, and consumer promotions are usually temporary price reductions or coupons. The cost in reduced profit, demonstrated mathematically through calculations of price elasticity, is severe. Besides, when the promotion is over, the manufacturer has not moved forward an inch in shoring up the brand franchise. Promotions bring volatile demand, whereas the producer seeks stable demand. By sustaining a brand image and building customer loyalty, on the other hand, theme advertising can stabilize demand. Moreover, this type of advertising is less likely than promotion is to invite destructive competitive retaliation. Calculation of the advertising elasticity of a brand indicates that sometimes even modest sales increases can produce healthy profit improvement. In a well-planned marketing campaign, there is often good reason to include trade or consumer promotion--to counter a leading competitor's moves, for example. But there is no point in carrying out wild swings at rivals in a struggle for market share. Mathematical techniques can aid the efficiency of marketing planning and put on a more rational basis the decision on where to put the dollars.

  3. Transcription Factor Binding Site Positioning in Yeast: Proximal Promoter Motifs Characterize TATA-Less Promoters

    PubMed Central

    Erb, Ionas; van Nimwegen, Erik

    2011-01-01

    The availability of sequence specificities for a substantial fraction of yeast's transcription factors and comparative genomic algorithms for binding site prediction has made it possible to comprehensively annotate transcription factor binding sites genome-wide. Here we use such a genome-wide annotation for comprehensively studying promoter architecture in yeast, focusing on the distribution of transcription factor binding sites relative to transcription start sites, and the architecture of TATA and TATA-less promoters. For most transcription factors, binding sites are positioned further upstream and vary over a wider range in TATA promoters than in TATA-less promoters. In contrast, a group of ‘proximal promoter motifs’ (GAT1/GLN3/DAL80, FKH1/2, PBF1/2, RPN4, NDT80, and ROX1) occur preferentially in TATA-less promoters and show a strong preference for binding close to the transcription start site in these promoters. We provide evidence that suggests that pre-initiation complexes are recruited at TATA sites in TATA promoters and at the sites of the other proximal promoter motifs in TATA-less promoters. TATA-less promoters can generally be classified by the proximal promoter motif they contain, with different classes of TATA-less promoters showing different patterns of transcription factor binding site positioning and nucleosome coverage. These observations suggest that different modes of regulation of transcription initiation may be operating in the different promoter classes. In addition we show that, across all promoter classes, there is a close match between nucleosome free regions and regions of highest transcription factor binding site density. This close agreement between transcription factor binding site density and nucleosome depletion suggests a direct and general competition between transcription factors and nucleosomes for binding to promoters.

    2012-01-01

    The sequencing of the human genome led to many insights into gene organization and structure. One interesting observation was the high frequency of bidirectional promoters characterized by two protein encoding genes whose promoters are arranged in a divergent or “head-to-head” configuration with less than 2000 base pairs of intervening sequence. Computational estimates published by various groups indicate that nearly 10% of the coding gene promoters are arranged in such a manner and the extent of this bias is a unique feature of mammalian genomes. Moreover, as a class, head-to-head promoters appear to be enriched in specific categories of gene function. Here we review the structure, composition, genomic properties and functional classifications of genes controlled by bidirectional promoters and explore the biological implication of these features.

    Bacterial endophytes ubiquitously colonize the internal tissues of plants, being found in nearly every plant worldwide. Some endophytes are able to promote the growth of plants. For those strains the mechanisms of plant growth-promotion known to be employed by bacterial endophytes are similar to the mechanisms used by rhizospheric bacteria, e.g., the acquisition of resources needed for plant growth and modulation of plant growth and development. Similar to rhizospheric plant growth-promoting bacteria, endophytic plant growth-promoting bacteria can act to facilitate plant growth in agriculture, horticulture and silviculture as well as in strategies for environmental cleanup (i.e., phytoremediation). Genome comparisons between bacterial endophytes and the genomes of rhizospheric plant growth-promoting bacteria are starting to unveil potential genetic factors involved in an endophytic lifestyle, which should facilitate a better understanding of the functioning of bacterial endophytes.

    Glycine betaine (betaine) has the highest cellular osmoprotective efficiency which does not accumulate in most glycophytes. The biosynthetic pathway for betaine in higher plants is derived from the oxidation of low-accumulating metabolite choline that limiting the ability of most plants to produce betaine. Halophilic methanoarchaeon Methanohalophilus portucalensis FDF1(T) is a model anaerobic methanogen to study the acclimation of water-deficit stresses which de novo synthesize betaine by the stepwise methylation of glycine, catalyzed by glycine sarcosine N-methyltransferase (GSMT) and sarcosine dimethylglycine N-methyltransferase. In this report, genes encoding these betaine biosynthesizing enzymes, Mpgsmt and Mpsdmt, were introduced into Arabidopsis. The homozygous Mpgsmt (G), Mpsdmt (S), and their cross, Mpgsmt and Mpsdmt (G × S) plants showed increased accumulation of betaine. Water loss from detached leaves was slower in G, S, and G × S lines than wild-type (WT). Pot-grown transgenic plants showed better growth than WT after 9 days of withholding water or irrigating with 300 mM NaCl. G, S, G × S lines also maintained higher relative water content and photosystem II activity than WT under salt stress. This suggests heterologously expressed Mpgsmt and Mpsdmt could enhance tolerance to drought and salt stress in Arabidopsis. We also found a twofold increase in quaternary ammonium compounds in salt-stressed leaves of G lines, presumably due to the activation of GSMT activity by high salinity. This study demonstrates that introducing stress-activated enzymes is a way of avoiding the divergence of primary metabolites under normal growing conditions, while also providing protection in stressful environments.

    Background Little is known about the effectiveness of strategies to enable people to achieve and maintain recommended levels of physical activity. Objectives To assess the effectiveness of interventions designed to promote physical activity in adults aged 16 years and older, not living in an institution. Search methods We searched The Cochrane Library (issue 1 2005), MEDLINE, EMBASE, CINAHL, PsycLIT, BIDS ISI, SPORTDISCUS, SIGLE, SCISEARCH (from earliest dates available to December 2004). Reference lists of relevant articles were checked. No language restrictions were applied. Selection criteria Randomised controlled trials that compared different interventions to encourage sedentary adults not living in an institution to become physically active. Studies required a minimum of six months follow up from the start of the intervention to the collection of final data and either used an intention-to-treat analysis or, failing that, had no more than 20% loss to follow up. Data collection and analysis At least two reviewers independently assessed each study quality and extracted data. Study authors were contacted for additional information where necessary. Standardised mean differences and 95% confidence intervals were calculated for continuous measures of self-reported physical activity and cardio-respiratory fitness. For studies with dichotomous outcomes, odds ratios and 95% confidence intervals were calculated. Main results The effect of interventions on self-reported physical activity (19 studies; 7598 participants) was positive and moderate (pooled SMD random effects model 0.28 95% CI 0.15 to 0.41) as was the effect of interventions (11 studies; 2195 participants) on cardio-respiratory fitness (pooled SMD random effects model 0.52 95% CI 0.14 to 0.90). There was significant heterogeneity in the reported effects as well as heterogeneity in characteristics of the interventions. The heterogeneity in reported effects was reduced in higher quality studies, when physical

    The evolution of health promotion in Canada between 1986 and 2006 is characterized by three major eras: Health Promotion in the Limelight, 1986-1992, Health Promotion Behind the Scenes, 1993-2003, and Health Promotion Restaged, 2003-2006. These eras are illustrated using the Canadian Heart Health Initiative as an example. The first era, backed by strong federal government leadership and support, was a progressive time of developing concepts, collaborations and infrastructure for health promotion across the country. Despite significant progress, by the end of this era, health promotion was neither sufficiently developed nor funded to make it a cornerstone of the health system. In addition, the emphasis was heavily biased towards changing individual behaviour. In the second era, health promotion continued to develop in pockets across the country and debates within the field intensified. However, these events went largely unnoticed and massive overall cuts at federal and provincial levels of government made acute care a much higher priority than health promotion. The third era, mostly shaped by fears linked to public health threats, saw a restaging of health promotion through efforts to strengthen public health infrastructure. Nevertheless, at the end of this era, the necessary intersectoral partnerships (such as in health, housing, education, food, income) remained scarce, and little progress was made to decrease health inequalities. The Canadian Heart Health Initiative was implemented over the same time period as the three eras. Its legacy includes collegial relationships across various levels of government and with non-government organizations, a culture that values pan-Canadian initiatives, and support for integration of research, evaluation, surveillance, policy and practice. It remains to be seen how quickly it will be possible to advance the vision of health promotion conceived during the Limelight Era in Canada.

    The ability to modulate gene expression is an important genetic tool in systems biology and biotechnology. Here, we demonstrate that a previously published easy and fast PCR-based method for modulating gene expression in lactic acid bacteria is also applicable to Corynebacterium glutamicum. We constructed constitutive promoter libraries based on various combinations of a previously reported C. glutamicum -10 consensus sequence (gngnTA(c/t)aaTgg) and the Escherichia coli -35 consensus, either with or without an AT-rich region upstream. A promoter library based on consensus sequences frequently found in low-GC Gram-positive microorganisms was also included. The strongest promoters were found in the library with a -35 region and a C. glutamicum -10 consensus, and this library also represents the largest activity span. Using the alternative -10 consensus TATAAT, which can be found in many other prokaryotes, resulted in a weaker but still useful promoter library. The upstream AT-rich region did not appear to affect promoter strength in C. glutamicum. In addition to the constitutive promoters, a synthetic inducible promoter library, based on the E. coli lac-promoter, was constructed by randomizing the 17-bp spacer between -35 and -10 consensus sequences and the sequences surrounding these. The inducible promoter library was shown to result in β-galactosidase activities ranging from 284 to 1,665 Miller units when induced by IPTG, and the induction fold ranged from 7-59. We find that the synthetic promoter library (SPL) technology is convenient for modulating gene expression in C. glutamicum and should have many future applications, within basic research as well as for optimizing industrial production organisms.

    This data article tested whether polymorphisms within the dopamine D4 receptor (DRD4) gene promoter can lead to differences in the promoter activity. The variants, a 120-bp variable number tandem repeat (VNTR), -906 T/C, -809 G/A, -616G/C, and -521C/T, were introduced into the DRD4 promoter and the promoter activity was measured in a neural cell line using the luciferase assay. However, no differences were detected among the haplotypes investigated, and the in vitro data obtained from our protocol could not support the involvement of DRD4 promoter polymorphisms in heritable human traits.

  14. Overview of tumor promotion in animals

    1983-01-01

    Our present understanding of two-stage carcinogenesis encompasses almost four decades of research. Evidence for chemical promotion or cocarcinogenesis was first provided by Berenblum, who reported that a regimen of croton oil (weak or noncarcinogenic) applied alternately with small doses of benzo(a)pyrene (BP) to mouse skin induced a larger number of tumors than BP alone. Subsequently, Moltram found that a single subcarcinogenic dose of BP followed by multiple applications of croton oil could induce a large number of skin tumors. These investigations as well as a number of others, such as Boutwell, Van Duuren and Hecker, were responsible in defining many important aspects of the initiation and promotion of two-stage carcinogenesis. The initiation stage in mouse skin requires only a single application of either a direct-acting carcinogen or a procarcinogen and is essentially an irreversible step which as data suggests probably involves a somatic cell mutation. The promotion stage in mouse skin can be accomplished by a wide variety of weak or noncarcinogenic agents and is initially reversible later becoming irreversible. Current information suggests that skin tumor promoters are not mutagenic but bring about a number of important epigenetic changes, such as epidermal hyperplasia, and an increase in polyamines, prostaglandins and dark basal keratinocytes as well as other embryonic conditions. Recently, tumor promotion in mouse skin was shown to consist of at least two stages, in which each stage can be accomplished by either a known promoter or a weak or nonpromoting agent. Some of the important characteristics of the first stage of promotion are: (1) only one application of a first-stage promoter, such as phorbol ester tumor promoters, calcium ionophore A23187, hydrogen peroxide and wounding is needed; (2) the action is partially irreversible; (3) an increase in dark basal keratinocytes and prostaglandins is important; and (4) such an increase can be inhibited by

    In the last decade, a revolution has been occurring in the field of health promotion. Guided to a large extent by position papers disseminated by the World Health Organization (WHO) Europe Health Promotion Office, and furthered by the Ottawa Charter, the Epp Report in Canada, the Healthy Cities project, as well as by other efforts, this new health promotion movement has introduced new ideas, new language, and new concepts about what constitutes health and how health promotion efforts should be configured to achieve health. Punctuated by the terms like empowerment and community participation, this movement has generated a whole new discourse about the theory and practice of health promotion. This paper explores the multiple meanings that surround these terms, and the implications for practice, by addressing questions like: What does health mean in this new context? What is empowerment? What does participation look like? Has the tyranny of the professional been replaced by the tyranny of the community? Has anything changed about the practice of health promotion other than the language? Finally, it is argued that an acknowledgment of the multidimensionality of these concepts may facilitate their translation from rhetoric into health promotion practice.

    Summary Transcription initiation is the key step in gene expression in bacteria, and it is therefore studied for both theoretical and practical reasons. Promoters, the traffic lights of transcription initiation, are used as construction elements in biotechnological efforts to coordinate ‘green waves’ in the metabolic pathways leading to the desired metabolites. Detailed analyses of Corynebacterium glutamicum promoters have already provided large amounts of data on their structures, regulatory mechanisms and practical capabilities in metabolic engineering. In this minireview the main aspects of promoter studies, the methods developed for their analysis and their practical use in C. glutamicum are discussed. These include definitions of the consensus sequences of the distinct promoter classes, promoter localization and characterization, activity measurements, the functions of transcriptional regulators and examples of practical uses of constitutive, inducible and modified promoters in biotechnology. The implications of the introduction of novel techniques, such as in vitro transcription and RNA sequencing, to C. glutamicum promoter studies are outlined. PMID:23305350

    Much effort has been devoted to the metabolic engineering of Klebsiella pneumoniae; however, our knowledge of the actual expression level of promoters used in K. pneumoniae is limited. In this study, the expression levels of three promoters were compared systematically by using the lacZ reporter gene with different carbon sources in K. pneumoniae. The results showed that, although promoters PT5 and Ptac designed for Escherichia coli were functional, PT5 appeared more efficient and the induction/repression ratio of Ptac was decreased extremely in K. pneumoniae. The basal level of Ptac for lacZ expression reached 396.5 U/mg, which was 9.5-fold higher compared with PT5 in LB medium, indicating Ptac can be used as an efficient "constitutive" promoter as well as an efficient induced promoter in K. pneumoniae. In different carbon sources medium, a newly constructed endogenous constitutive Pbud proved to be a stable and weak promoter. On the basis of our data, a set of Pbud and Ptac promoters could meet the broad range (about 1,000 orders of magnitude) of gene expression needed for engineered K. pneumoniae in glycerol-based medium.

    Virophages have crucial roles in ecosystems and are the transport vectors of genetic materials. To shed light on regulation and control mechanisms in virophage--host systems as well as evolution between virophages and their hosts, the promoter motifs of virophages were predicted on the upstream regions of start codons using an analytical tool for prediction of promoter motifs: Multiple EM for Motif Elicitation. Seventeen potential promoter motifs were identified based on the E-value, location, number and length of promoters in genomes. Sputnik and zamilon motif 2 with AT-rich regions were distributed widely on genomes, suggesting that these motifs may be associated with regulation of the expression of various genes. Motifs containing the TCTA box were predicted to be late promoter motif in mavirus; motifs containing the ATCT box were the potential late promoter motif in the Ace Lake mavirus . AT-rich regions were identified on motif 2 in the Organic Lake virophage, motif 3 in Yellowstone Lake virophage (YSLV)1 and 2, motif 1 in YSLV3, and motif 1 and 2 in YSLV4, respectively. AT-rich regions were distributed widely on the genomes of virophages. All of these motifs may be promoter motifs of virophages. Our results provide insights into further exploration of temporal expression of genes in virophages as well as associations between virophages and giant viruses.

    We have developed a novel bi-directional promoter (FsFfCBD) by placing two heterogeneous core-promoters from the Figwort mosaic virus sub-genomic transcript promoter (FsCP, -69 to +31) and Cauliflower mosaic virus 35S promoter (CCP, -89 to +1) respectively on upstream (5') and downstream (3') ends of a tri-hybrid enhancer (FsEFfECE), in reverse orientation. The FsEFfECE domain encompasses three heterologous enhancer fragments from Figwort mosaic virus sub-genomic transcript promoter (FsE, 101 bp, -70 to -170), Figwort mosaic virus full-length transcript promoter (FfE, 196 bp, -249 to -54) and Cauliflower mosaic virus 35S promoter (CE, 254 bp, -343 to -90). The bi-directional nature of the FsFfCBD promoter (coupled to GFP and GUS) was established both in transient systems (onion epidermal cells and tobacco protoplasts) and transgenic plant (Nicotiana tabacum samsun NN) by monitoring the simultaneous expression of GFP and GUS employing fluorescence (for GFP) and biochemical (for GUS) based assays. In transgenic plants, the FsFfCBD promoter was found to be 6.8 and 2.5 times stronger than two parent promoters; Fs and FfC respectively. The bi-directional compound promoter FsFfCBD, composed of three heterologous enhancers with enhanced activity could become a valuable additional tool for efficient plant metabolic engineering and molecular pharming.

    This paper considers the promotion cost sharing decision between a supplier and a retailer. The customer demand is affected by both national and local promotional effects while the local promotional effect on a customer is dependent on the distance between the retailer and this customer. We propose a continuous approximation approach to modelling the sum of the customer demand in the whole market area served by the retailer. A model is provided to help managers decide on the retail price, the local advertising expenditure, the national advertising expenditure, and the supplier participation rate, with consideration of the influence of distance on the promotional effect. We also find that the supplier's promotion cost sharing rate increases as the market size increases or the influence of distance on the promotional effect decreases. A numerical example is given to show that the nature of distance-dependent promotional effect has a significant impact on the decisions and profits.

    Though not necessarily using the same terminology historically, people concerned with the public's health have long been addressing the social context of non-communicable diseases (NCDs) and the actions of promoting health. This commentary places the current interest in NCDs within that history and discusses the challenges that continue to face institutions in dealing with NCDs. It makes a particular plea for the role of health promotion as the area of public health that takes actions to address the global burden of NCDs. Without a health promotion focus, we will just continue to describe the NCD burden rather than reduce it.

    During T-lymphocyte development, the T-cell antigen receptor (TCR) gene expression is controlled by its promoter and enhancer elements and regulated in tissue- and development stage-specific manner. To uncover the promoter function and to define positive and negative regulatory elements in TCR gene promoters, the promoter activities from 13 human TCR Vbeta genes were determined by the transient transfection system and luciferase reporter assay. Although most of the TCR Vbeta gene promoters that we tested are inactive by themselves, some promoters were found to be constitutively strong. Among them, Vbeta6.7 is the strongest. 5'-Deletion and fragmentation experiments have narrowed the full promoter activity of Vbeta6.7 to a fragment of 147 base pairs immediately 5' to the transcription initiation site. A decanucleotide motif with the consensus sequence AGTGAYRTCA has been found to be conserved in most TCR Vbeta gene promoters. There are three such decamer motifs in the promoter region of Vbeta6.7, and the contribution of each such motif to the promoter activity has been examined. Further site-directed mutagenesis analyses showed that: 1) when two Ts in the decamer were mutated, the promoter activity was totally abolished; 2) when two additional nucleotides 3' to the end of decamer were mutated, the promoter activity was decreased to two-thirds of the full level; and 3) when the element with the sequence AGTGATGTCACT was inserted into other promoters, the original weak promoters become very strong. Taken together, our data suggest that the positive regulatory element in Vbeta6.7 should be considered a dodecamer rather than a decamer and that it confers strong basal transcriptional activity on TCR Vbeta genes.

METHODS A qualitative study with data obtained from in-depth analysis that included participant observation, interviews with managers, coordinators, professionals and participants from 29 practices reported as successful for promoting health in six municipalities of the metropolitan region of Belo Horizonte, MG, Southeastern Brazil, in 2011. The variables of the study were concept, dimension, dissemination and ease of access, identified in practices guided by content analysis. RESULTS The results indicate a conceptual and methodological uncertainty about health promotion as evidenced by conflicting objects and contradictory purposes. The practices differ in size, coverage and ease of access, determined by inter-sector coordination and political and financial investment.

    In order to maximize cost efficiency from scarce marketing resources, marketers are facing the problem of which group of consumers to target for promotions. We propose to use a decision theoretical approach to model this strategic situation. According to one promotion model that we develop, marketers balance between probabilities of successful persuasion and the expected profits on a diffusion scale, before making their decisions. In the other promotion model, the cost for identifying influence information is considered, and marketers are allowed to ignore individual heterogeneity. We apply the proposed approach to two threshold influence models, evaluate the utility of each promotion action, and provide discussions about the best strategy. Our results show that efforts for targeting influentials or easily influenced people might be redundant under some conditions.

    The purpose of this paper is to describe the multifaceted nature and benefits of worksite health promotion programs (WHPPs), with emphasis on the college setting. An assessment of the peer-reviewed literature was conducted of articles published since 2000. Several search engines were accessed and selected key words were used. Most studies examining WHPPs have focused on return on investment and productivity. Research that targets the softer side-benefits of health promotion programs in the workplace is less available. Although the college setting offers some advantages for implementing health promotion programs. They may also have unique challenges due to their large and diverse employee population. There is little research to show the effectiveness and unique challenges of college-based health promotion programs. PMID:25861657

Prior to this strategy, and subsequently, studies have explored the nature and extent of health promotion in nursing education. This article extensively reviews this body of literature. Overall, the literature, both included in this review and its supporting discussion, presents a picture suggesting that the call for effective inclusion of health promotion has in many cases gone unheeded. The literature also identifies that the educational delivery of broader elements of health promotion is muted in comparison to the 'traditional' constructs of health education. Considerations for wider reform, born out of the literature, are presented.

    The emphasis of Australian Government policy is on the promotion of good health in later life and positive experiences with ageing. Conceptually, a new gerontology framework has replaced the study of disease, decline, loss and disability. Within this framework, health promotion offers a mechanism by which individuals can be assisted to create environments that offer better opportunities for continued participation in society and improved quality of health and self-care. Oral health is instrumental to older people's health, life satisfaction, quality of life and perception of self. Australia is culturally diverse, composed of numerous ethno-cultural groups coexisting within a larger, predominant culture, creating a multicultural and multiracial society. However, despite this cultural diversity, the well documented ageing profile of the Australian population and repeated calls for comprehensive geriatric assessment, the oral health of older adults remains a challenge for oral health providers and for society. A major challenge will be to translate existing knowledge and experience of disease prevention and health promotion into appropriate programmes for older adults. Health promotion is the key to improving oral health in later life as it encourages older adults to be proactive in regard to their health. Therefore, increased efforts should be directed towards identifying opportunities for health promotion activities and the development of community based models that encourage older people to improve and maintain their oral health. Ignoring opportunities for health promotion may increase inequalities in oral health and may lead to even greater demands for curative and oral rehabilitative services from these groups This article firstly provides a brief rationale for oral health promotion. Its second part explores the influence of culture on health beliefs, behaviours and outcomes in older adults and how oral health can relate to cultural background. The last section

    Fermentation at higher temperatures can potentially reduce the cooling cost in large-scale fermentation and reduce the contamination risk. Thus, the thermotolerant yeast, Kluyveromyces marxianus, which can grow and ferment at elevated temperatures, is a promising biotechnological tool for future applications. However, the promoters used in K. marxianus are not well characterized, especially at elevated temperatures, which is important in efficient metabolic pathway construction. In this study, six constitutive promoters (P(TDH3), P(PGK), and P(ADH1) from both Saccharomyces cerevisiae and K. marxianus) were evaluated in K. marxianus through the heterologous expression of the KlLAC4, GUSA, and SH BLE genes at various temperatures, with various carbon sources and oxygen conditions. The expression was evaluated at the transcription and protein level using real-time PCR and protein activity determination to eliminate the effect of heterologous protein stability. While the transcription of all the promoters decreased at higher temperatures, the order of their promoting strength at various temperatures with glucose as the carbon source was P(KmPGK) > P(KmTDH3) > P(ScPGK) > P(ScTDH3) > P(KmADH1) > P(ScADH1). When glycerol or xylose was supplied as the carbon source at 42 °C, the order of promoter strength was P(KmPGK) > P(ScPGK) > P(KmADH1) > P(ScADH1) > P(ScTDH3) > P(KmTDH3). The promoter activity of P TDH3 decreased significantly, while the promoter activity of both of the P(ADH1) promoters increased. Oxygen conditions had non-significant effect. The results of this study provide important information for fine-tuned pathway construction for the metabolic engineering of K. marxianus.

    An increasing number of faculty members are choosing the nontenured path in academia. These faculty members bring expertise in teaching that must be recognized and valued. With the shortage of nurse educators, procedures to attract and retain these faculty members are needed. To address this problem, guidelines for promotion of nontenured faculty were developed. The authors describe the development process and the final criteria for promotion.

  1. Kinetic analysis of T7 RNA polymerase-promoter interactions with small synthetic promoters.

    PubMed

    Martin, C T; Coleman, J E

    1987-05-19

    Specific interactions between T7 RNA polymerase and its promoter have been studied by a simple steady-state kinetic assay using synthetic oligonucleotide promoters that produce a short five-base message. A series of promoters with upstream lengths extending to promoter positions -19, -17, -14, and -12 show that promoters extending to -19 and -17 produce very specific transcripts with initiation rate constant Kcat = 50 min-1 and a Michaelis constant Km = 0.02 microM, indicating that the consensus sequence to position -17 is sufficient for maximum promoter usage. Shortening the upstream region of the promoter to -14 substantially increases Km (0.3 microM) but does not significantly reduce the maximum velocity (kcat = 30 min-1). Finally, truncation of the promoter at position -12 results in extremely low levels of specific transcription. The coding and noncoding strands appear to make different contributions to promoter recognition. Although the double-stranded promoter of upstream length -12 is very poor as a transcription template, extension of only the noncoding strand to -17 very significantly improves both Kcat and Km. In contrast, extension of only the coding strand results in no significant improvement. Substitution of an AT base pair at position -10 by CG (as found in T3 RNA polymerase promoters) produces a 10-fold increase in Km, with little effect on Kcat. Comparison of two promoters containing a base pair mismatch at this site (AG or CT) demonstrates that promoter recognition is very sensitive to the nature of the base on the noncoding strand and is only slightly affected by the presence of a mismatch created by a wrong base in the coding strands.(ABSTRACT TRUNCATED AT 250 WORDS)

    Mexico is undergoing profound health reform, extending health insurance to previously uninsured populations and changing the way health care services are delivered. Legislation enacted in 2003 and implemented in 2004 mandated funding and infrastructure that will allow 52% of Mexico's population to access medical care at no cost by 2010. This ambitious social reform has not been without challenges, particularly financial sustainability. Health promotion, because of its potential to prevent or delay chronic diseases and injuries and their associated costs, is a key component of health care reform. In 2006, the Ministry of Health's General Directorate of Health Promotion developed the Health Promotion Operational Model. Based on Ottawa Charter functions, the model integrates health promotion activities within the overall health care system. The main goal of this model is to build strong human capital and to improve organizational capacity for health promotion starting at the local level by training health care personnel to implement health promotion activities. Organizational development workshops started in 2006, and implementation plans in all 32 Mexican states were in place by end of 2008.

    For many years, gene expression in the three cellular domains has been studied in an attempt to discover sequences associated with the regulation of the transcription process. Some specific transcriptional features were described in viruses, although few studies have been devoted to understanding the evolutionary aspects related to the spread of promoter motifs through related viral families. The discovery of giant viruses and the proposition of the new viral order Megavirales that comprise a monophyletic group, named nucleo-cytoplasmic large DNA viruses (NCLDV), raised new questions in the field. Some putative promoter sequences have already been described for some NCLDV members, bringing new insights into the evolutionary history of these complex microorganisms. In this review, we summarize the main aspects of the transcription regulation process in the three domains of life, followed by a systematic description of what is currently known about promoter regions in several NCLDVs. We also discuss how the analysis of the promoter sequences could bring new ideas about the giant viruses' evolution. Finally, considering a possible common ancestor for the NCLDV group, we discussed possible promoters' evolutionary scenarios and propose the term "MEGA-box" to designate an ancestor promoter motif ('TATATAAAATTGA') that could be evolved gradually by nucleotides' gain and loss and point mutations.

    A firefly luciferase (FLuc) counts among the most popular reporters of present-day molecular and cellular biology. In this study, we report a cryptic promoter activity in the luc+ gene, which is the most frequently used version of the firefly luciferase. The FLuc coding region displays cryptic promoter activity both in mammalian and yeast cells. In human CCL13 and Huh7 cells, cryptic transcription from the luc+ gene is 10–16 times weaker in comparison to the strong immediate-early cytomegalovirus promoter. Additionally, we discuss a possible impact of the FLuc gene cryptic promoter on experimental results especially in some fields of the RNA-oriented research, for example, in analysis of translation initiation or analysis of miRNA/siRNA function. Specifically, we propose how this newly described cryptic promoter activity within the FLuc gene might contribute to the previous determination of the strength of the cryptic promoter found in the cDNA corresponding to the hepatitis C virus internal ribosome entry site. Our findings should appeal to the researchers to be more careful when designing firefly luciferase-based assays as well as open the possibility of performing some experiments with the hepatitis C virus internal ribosome entry site, which could not be considered until now.

    Promoter shutoff is a general method for analyzing essential genes, but in the fungus Aspergillus oryzae, no tightly repressed promoters have been reported. To overcome the current limitations of conditional promoters, we examined sorbitol- and galactose-responsive genes using microarrays to identify regulatable genes with only minor physiological and genetic effects. We identified two sorbitol-induced genes (designated as sorA and sorB), cloned their promoters, and built a regulated egfp and brlA expression system. Growth medium-dependent enhanced green fluorescence protein (EGFP) fluorescence and conidiation were confirmed for egfp and brlA under the control of their respective promoters. We also used this shutoff system to regulate the essential rhoA, which demonstrated the expected growth inhibition under repressed growth conditions. Our new sorbitol promoter shutoff system developed can serve as a valuable new tool for essential gene analyses of filamentous fungi.

    Conducting a health needs assessment is an important if not essential first step for health promotion planning. This paper explores how health needs assessments may be further strengthened for health promotion planning via an assessment of environmental assets rooted in the multiple environments (policy, information, social and physical environments) that shape health and behavior. Guided by a behavioral-ecological perspective- one that seeks to identify environmental assets that can influence health behavior, and an implementation science perspective- one that seeks to interweave health promotion strategies into existing environmental assets, we present a basic framework for assessing environmental assets and review examples from the literature to illustrate the incorporation of environmental assets into health program design. Health promotion practitioners and researchers implicitly identify and apply environmental assets in the design and implementation of health promotion interventions;this paper provides foundation for greater intentionality in assessing environmental assets for health promotion planning.

    Versican is a large chondroitin sulfate proteoglycan of the extracellular matrix that is involved in a variety of cellular processes. We showed previously that versican, which is overexpressed in cutaneous melanomas as well as in premalignant lesions, contributes to melanoma progression, favoring the detachment of cells and the metastatic dissemination. Here, we investigated the transcriptional regulation of the versican promoter in melanoma cell lines with different levels of biological aggressiveness and stages of differentiation. We show that versican promoter up-regulation accounts for the differential expression levels of mRNA and protein detected in the invasive SK-mel-131 human melanoma cells. The activity of the versican promoter increased 5-fold in these cells in comparison with that measured in non-invasive MeWo melanoma cells. Several transcriptional regulatory elements were identified in the proximal promoter, including AP-1, Sp1, AP-2, and two TCF-4 sites. We show that promoter activation is mediated by the ERK/MAPK and JNK signaling pathways acting on the AP-1 site, suggesting that BRAF mutation present in SK-mel-131 cells impinge upon the up-regulation of the versican gene through signaling elicited by the ERK/MAPK pathway. This is the first time the AP-1 transcription factor family has been shown to be related to the regulation of versican expression. Furthermore, deletion of the TCF-4 binding sites caused a 60% decrease in the promoter activity in SK-mel-131 cells. These results showing that AP-1 and TCF-4 binding sites are the main regulatory regions directing versican production provide new insights into versican promoter regulation during melanoma progression.

    Despite advances in targeted therapies, the treatment of advanced melanoma remains an exercise in disease management, hence a need for biomarkers for identification of at-risk primary melanoma patients. In this study, we aimed to assess the prognostic value of TERT promoter mutations in primary melanomas. Tumors from 300 patients with stage I/II melanoma were sequenced for TERT promoter and BRAF/NRAS mutations. Cumulative curves were drawn for patients with and without mutations with progression-free and melanoma-specific survival as outcomes. Cox proportional hazard regression models were used to determine the effect of the mutations on survivals. Individually, presence of TERT promoter and BRAF/NRAS mutations associated with poor disease-free and melanoma-specific survival with modification of the effect by the rs2853669 polymorphism within the TERT promoter. Hazard ratio (HR) for simultaneous occurrence of TERT promoter and BRAF/NRAS mutations for disease-free survival was 2.3 (95% CI 1.2-4.4) and for melanoma-specific survival 5.8 (95% CI 1.9-18.3). The effect of the mutations on melanoma-specific survival in noncarriers of variant allele of the polymorphism was significant (HR 4.5, 95% CI 1.4-15.2) but could not be calculated for the carriers due to low number of events. The variant allele per se showed association with increased survival (HR 0.3, 95% CI 0.1-0.9). The data in this study provide preliminary evidence that TERT promoter mutations in combination with BRAF/NRAS mutations can be used to identify patients at risk of aggressive disease and the possibility of refinement of the classification with inclusion of the rs2853669 polymorphism within TERT promoter.

  5. Reduced capacity of alternative σs to melt promoters ensures stringent promoter recognition

    2009-01-01

    In bacteria, multiple σs direct RNA polymerase to distinct sets of promoters. Housekeeping σs direct transcription from thousands of promoters, whereas most alternative σs are more selective, recognizing more highly conserved promoter motifs. For σ32 and σ28, two Escherichia coli Group 3 σs, altering a few residues in Region 2.3, the portion of σ implicated in promoter melting, to those universally conserved in housekeeping σs relaxed their stringent promoter requirements and significantly enhanced melting of suboptimal promoters. All Group 3 σs and the more divergent Group 4 σs have nonconserved amino acids at these positions and rarely transcribe >100 promoters. We suggest that the balance of “melting” and “recognition” functions of σs is critical to setting the stringency of promoter recognition. Divergent σs may generally use a nonoptimal Region 2.3 to increase promoter stringency, enabling them to mount a focused response to altered conditions. PMID:19833768

    Synthetic promoters can control a gene's timing, location, and expression level. The PromoterCAD web server ( http://promotercad.org ) allows the design of synthetic promoters to control plant gene expression, by novel arrangement of cis-regulatory elements. Recently, we have expanded PromoterCAD's scope with additional plant and animal data: (1) PLACE (Plant Cis-acting Regulatory DNA Elements), including various sized sequence motifs; (2) PEDB (Mammalian Promoter/Enhancer Database), including gene expression data for mammalian tissues. The plant PromoterCAD data now contains 22 000 Arabidopsis thaliana genes, 2 200 000 microarray measurements in 20 growth conditions and 79 tissue organs and developmental stages, while the new mammalian PromoterCAD data contains 679 Mus musculus genes and 65 000 microarray measurements in 96 tissue organs and cell types ( http://promotercad.org/mammal/ ). This work presents step-by-step instructions for adding both regulatory motif and gene expression data to PromoterCAD, to illustrate how users can expand PromoterCAD functionality for their own applications and organisms.

    In the present study, we developed a set of three chimeric/hybrid promoters namely FSgt-PFlt, PFlt-UAS-2X and MSgt-PFlt incorporating different important domains of Figwort Mosaic Virus sub-genomic transcript promoter (FSgt, -270 to -60), Mirabilis Mosaic Virus sub-genomic transcript promoter (MSgt, -306 to -125) and Peanut Chlorotic Streak Caulimovirus full-length transcript promoter (PFlt-, -353 to +24 and PFlt-UAS, -353 to -49). We demonstrated that these chimeric/hybrid promoters can drive the expression of reporter genes in different plant species including tobacco, Arabidopsis, petunia, tomato and spinach. FSgt-PFlt, PFlt-UAS-2X and MSgt-PFlt promoters showed 4.2, 1.5 and 1.2 times stronger GUS activities compared to the activity of the CaMV35S promoter, respectively, in tobacco protoplasts. Protoplast-derived recombinant promoter driven GFP showed enhanced accumulation compared to that obtained under the CaMV35S promoter. FSgt-PFlt, PFlt-UAS-2X and MSgt-PFlt promoters showed 3.0, 1.3 and 1.0 times stronger activities than the activity of the CaMV35S² (a modified version of the CaMV35S promoter with double enhancer domain) promoter, respectively, in tobacco (Nicotiana tabacum, var. Samsun NN). Alongside, we observed a fair correlation between recombinant promoter-driven GUS accumulation with the corresponding uidA-mRNA level in transgenic tobacco. Histochemical (X-gluc) staining of whole transgenic seedlings and fluorescence images of ImaGene Green™ treated floral parts expressing the GUS under the control of recombinant promoters also support above findings. Furthermore, we confirmed that these chimeric promoters are inducible in the presence of 150 μM salicylic acid (SA) and abscisic acid (ABA). Taken altogether, we propose that SA/ABA inducible chimeric/recombinant promoters could be used for strong expression of gene(s) of interest in crop plants.

    Most Arabidopsis long interspersed elements (LINEs, called ATLNs) have two open reading frames, orf1 and orf2. In the 5' untranslated regions (UTRs) located upstream of orf1, the most proximal segments of tens of base pairs long are not homologous even in two ATLN members with almost identical sequences. In this study, we first show that RT-PCR products from ATLN39, a member of ATLN, can be detected only in total RNA from the hypomethylation mutant ddm1 or from suspension-cultured cells treated with a DNA methylation inhibitor 5-azacytidine, indicating that the expression of ATLN39 is negatively regulated by DNA methylation. We then show that orf1 fused in frame with the luciferase (luc) gene is expressed in suspension-cultured cells of A. thaliana when the 5' UTR is present in the region upstream of orf1. Analysis of deletion in the 5' UTR revealed that the 5' UTR has two promoters, designated here as P1 and P2. Analysis of transcripts by 5' RACE showed that their 5' ends were located at sites immediately upstream of the P1 region or at sites downstream of the P2 region. This observation and the fact that the P1 region contains no TATA sequence indicate that P1 is an internal promoter that initiates transcription from sites upstream of the promoter. A sequence containing GGCGA with a CpG methylatable site is conserved in the P1 regions in members closely related to ATLN39. The P2 region, however, contains the TATA sequence as well as another sequence with a CpG site. The TATA sequence is conserved in members closely related to ATLN39 but not in the other ATLN members, suggesting that P2 is the promoter uniquely present in the ATLN39-related members. Transcripts from promoter P1 can be used as templates to give new copies proficient in retroposition, but those from promoter P2 cannot because of the lack of the proximal half region of the 5' UTR sequence. Transcripts from promoter P2, as well as those from promoter P1 can, however, be used for the production of a

    Mu promoters active during the lytic cycle were located by isolating RNA at various times after induction of Mu prophages, radiolabeling it by capping in vitro, and hybridizing it to Mu DNA fragments on Southern blots. Signals were detected from four new promoters in addition to the previously characterized P{sub e} (early), P{sub cM} (repressor), and P{sub mom} (late) promoters. A major signal upstream of C was first observed at 12 min and intensified thereafter with RNA from cts and C amber but not replication-defective prophages; these characteristics indicate that this signal arises from a middle promoter, which we designate P{sub m}. With 20- and 40-min RNA, four additional major signals originated in the C-lys, F-G-I, N-P, and com-mom regions. These signals were missing with RNA from C amber and replication-defective prophages and therefore reflected the activity of late promoters, one of which we presume was P{sub mom}. Uninduced lysogens showed weak signals from five regions, one from the early regulatory region, three between genes B and lys, and one near the late genes K, L, and M. The first of these probably resulted from P{sub cM} activity; the others remain to be identified.

  11. 'Settings' based health promotion: a review.

    2001-12-01

    Over the past 10 years, 'settings' based health promotion has become a central feature of efforts to promote health that recognize the significance of context. Emerging in part from a perception of an over-reliance on individualistic methods, the approach was built on a profound belief in its value and deployed a range of novel theoretical resources, mainly from organizational sociology and psychology. This initial enthusiasm has been maintained within policy directives, in the published literature and, from our own experience, amongst health promotion practitioners. At the same time, with the maturing of the approach, has come a healthy element of critical review. Drawing upon the literature and based upon our experiences within the Health Education Board for Scotland, this paper seeks to bring together a range of perspectives, casting a critical yet constructive eye on current settings theory and practice. The paper first reviews the nature of settings based work, highlighting the varied bases and expectations that underpin it. Similarly, the many factors that influence the ability of health promoters to deliver such activities are considered. In relation to the construction and delivery of such activity, the paper suggests that there needs to be an explicit and detailed assessment of the nature of the setting, the skills of the health promoter and the associated expectations.

    For many years, gene expression in the three cellular domains has been studied in an attempt to discover sequences associated with the regulation of the transcription process. Some specific transcriptional features were described in viruses, although few studies have been devoted to understanding the evolutionary aspects related to the spread of promoter motifs through related viral families. The discovery of giant viruses and the proposition of the new viral order Megavirales that comprise a monophyletic group, named nucleo-cytoplasmic large DNA viruses (NCLDV), raised new questions in the field. Some putative promoter sequences have already been described for some NCLDV members, bringing new insights into the evolutionary history of these complex microorganisms. In this review, we summarize the main aspects of the transcription regulation process in the three domains of life, followed by a systematic description of what is currently known about promoter regions in several NCLDVs. We also discuss how the analysis of the promoter sequences could bring new ideas about the giant viruses’ evolution. Finally, considering a possible common ancestor for the NCLDV group, we discussed possible promoters’ evolutionary scenarios and propose the term “MEGA-box” to designate an ancestor promoter motif (‘TATATAAAATTGA’) that could be evolved gradually by nucleotides’ gain and loss and point mutations.

    The Department of Health and Human Services initiated a pilot "microgrant" or small grants program in 2001 to promote Healthy People 2010 (HP 2010) implemented by the Yale-Griffin Prevention Research Center. This article describes the 103 agencies funded under this initiative and 67 control group agencies. It evaluates the HP 2010 focus areas targeted and the effectiveness of promoting HP 2010 objectives through microgrants. Forty-four percent of the grant recipients and 79% of the control group agencies indicated low levels of familiarity with HP 2010 goals. Changes in knowledge of HP 2010 goals for the microgrant group increased significantly from 5.24 +/- 3.67 to 7.83 +/- 1.86 (p < .05). The results suggest that microgrants can be a useful mechanism to plant the seeds for developing community and organizational capacity to define local health priorities, practice and test new initiatives or expand existing programs and promote knowledge about HP 2010.

    An artificial promoter system that can be fused upstream of any desired gene enabling reversible induction or repression of the expression of the gene at will in any suitable host cell or organisms by light is described. The design of the system is such that a molecule of the plant photoreceptor phytochrome is targeted to the specific DNA binding site in the promoter by a protein domain that is fused to the phytochrome and that specifically recognizes this binding site. This bound phytochrome, upon activation by light, recruits a second fusion protein consisting of a protein that binds to phytochrome only upon light activation and a transcriptional activation domain that activates expression of the gene downstream of the promoter.

    The objective of the study was to know how the Pankararu indigenous perceive their health situation and identify actions they prioritize as necessary to promote health in their community. Qualitative research, in which the declarations collected were subjected to the technique of analyzing the Collective Subject Discourse. It was identified that in the indigenous perception, as the health status of their community, there is a lack of general assistance, and a lack of professionals to assist them meeting their needs. In relation to actions that the Indigenous prioritize as necessary to promote the health of their community, it was highlighted provision of health unit with trained professionals and access to health education actions. It was, thus, proposed an overhaul of the organizations and establishments of the subsystems in promoting indigenous health.

    2013-09-01

    The development of an antimicrobial stewardship program (ASP) requires institutional support. However, obtaining sufficient institutional support is often a complex task that requires convincing the hospital's managers of the benefits of these programs. Additionally, in the design and implementation of an ASP, antimicrobial stewardship (AS) leaders need tools for diverse purposes, such as measuring antimicrobial consumption, education and training and designing protocols. In this review we provide useful information for AS promoters to facilitate the task of designing and implementing an ASP. First, we summarize information about various institutions that promote AS and include evidence that supports the need for and benefits of these programs. Then, several campaigns promoting AS are described. Finally, online resources for professionals dealing with AS are briefly summarized.

    The Peter principle has recently been investigated by means of an agent-based simulation, and its validity has been numerically corroborated. It has been confirmed that, within certain conditions, it can really influence in a negative way the efficiency of a pyramidal organization adopting meritocratic promotions. It was also found that, in order to bypass these effects, alternative promotion strategies should be adopted, as for example a random selection choice. In this paper, within the same line of research, we study promotion strategies in a more realistic hierarchical and modular organization, and we show the robustness of our previous results, extending their validity to a more general context. We also discuss why the adoption of these strategies could be useful for real organizations.

    2003-06-01

    We had previously described the use of relatively hydrophobic bile acids, notably UDCA (ursodeoxycholate) for the promotion of the apoptotic response to photodynamic therapy. Further study revealed that this effect occurred only when the target for photodamage was the anti-apoptotic protein Bcl-2. The efficacy of lysosomal photodamage, leading to a cleavage of the protein Bid, was not influenced by UDCA. Moreover, the apoptotic cell death resulting from treatment of cells with the non-peptidic Bcl-2 inhibitor HA 14-1 was also promoted by UDCA. These results are consistent with the proposal that the pro-apoptotic effects of UDCA are directed against Bcl-2, promoting inactivation by HA 14-1 or photodamage.

  19. TERT promoter mutations in thyroid cancer.

    PubMed

    Liu, Rengyun; Xing, Mingzhao

    2016-03-01

    The 2013 discovery of Telomerase reverse transcriptase (TERT) promoter mutations chr5, 1,295,228 C>T (C228T) and 1,295,250 C>T (C250T) in thyroid cancer represents an important event in the thyroid cancer field and much progress has occurred since then. This article provides a comprehensive review of this exciting new thyroid cancer field. The oncogenic role of TERT promoter mutations involves their creation of consensus binding sites for E-twenty-six transcriptional factors. TERT C228T is far more common than TERT C250T and their collective prevalence is, on average, 0, 11.3, 17.1, 43.2 and 40.1% in benign thyroid tumors, papillary thyroid cancer (PTC), follicular thyroid cancer, poorly differentiated thyroid cancer and anaplastic thyroid cancer, respectively, displaying an association with aggressive types of thyroid cancer. TERT promoter mutations are associated with aggressive thyroid tumor characteristics, tumor recurrence and patient mortality as well as BRAF V600E mutation. Coexisting BRAF V600E and TERT promoter mutations have a robust synergistic impact on the aggressiveness of PTC, including a sharply increased tumor recurrence and patient mortality, while either mutation alone has a modest impact. Thus, TERT with promoter mutations represents a prominent new oncogene in thyroid cancer and the mutations are promising new diagnostic and prognostic genetic markers for thyroid cancer, which, in combination with BRAF V600E mutation or other genetic markers (e.g. RAS mutations), are proving to be clinically useful for the management of thyroid cancer. Future studies will specifically define such clinical utilities, elucidate the biological mechanisms and explore the potential as therapeutic targets of TERT promoter mutations in thyroid cancer.

  20. Alternative promoters of gene MAGE4a

    SciTech Connect

    De Plaen, E.; Naerhuyzen, B.; De Smet, C.

    1997-03-01

    Gene MAGE-4 (HGMW-approved symbol MAGE4) is expressed in several types of tumors, but not in normal tissues, except testis and placenta. The 5{prime} end of this gene contains eight homologous exons spread over a 5.8-kb region. These exons are alternatively spliced to a unique second exon and a unique third exon, which encodes a protein of 317 amino acids. The analysis of transcripts found in testis, placenta, and a sarcoma cell line showed that each of the alternative first exons is used in at least one of these tissues. Various regions of the promoter of the fifth alternative exon (1.5) were cloned in a luciferase reporter plasmid, and the constructs were transfected in a sarcoma cell line that expresses MAGE-4. Two Ets motifs located between positions -70 and -29 relative to the transcription start site were found to drive 55% of the promoter activity. A region containing an Sp1 consensus binding site located upstream of the two Ets motifs was found to be responsible for 44% of the transcriptional activity. MAGE-4a promoters 1.4 and 1.6, which also contain the Sp1 and the two Ets binding motifs, supported a level of transcription comparable to that of promoter 1.5, whereas promoter 1.1, which contains only one Ets binding site, was sixfold less active. In line with observations made with gene MAGE-1 (HGMW-approved symbol MAGE1), we found that promoter 1.5 stimulated a high level of transcription in a melanoma cell line that does not express MAGE-4. This suggests that the tumor-specific expression of MAGE genes is not determined by the presence of specific transcription factors. 26 refs., 7 figs., 2 tabs.

    2016-01-01

    A critical component of the progression of a successful academic career is being promoted in rank. Early-career faculty are required to have an understanding of appointment, promotion, and tenure (APT) guidelines, but many factors often impede this understanding, thwarting a smooth and planned promotion pathway for professional advancement. This article outlines the steps taken by an APT committee to improve the promotion process from instructor to assistant professor. Six sigma's DMAIC improvement model was selected as the guiding operational framework to remove variation in the promotion process. After faculty handbook revisions were made, several checklists developed, and a process review rubric was implemented; recently promoted faculty were surveyed on satisfaction with the process. Faculty opinions captured in the survey suggest increased transparency in the process and perceived support offered by the APT committee. Positive outcomes include a strengthened faculty support framework, streamlined promotion processes, and improved faculty satisfaction. Changes to the APT processes resulted in an unambiguous and standardized pathway for successful promotion.

    The spirostanic steroidal side-chain of diosgenin and hecogenin was modified to produce 22-oxocholestane derivatives. This type of side-chain was obtained in good yields through a straightforward four-step pathway. These compounds show potent brassinosteroid-like growth promoting activity evaluated via the rice lamina joint inclination bioassay. This is the first report of steroidal skeletons bearing the 22-oxocholestane side-chain and preserving the basic structure (A-D rings) from their corresponding parent compounds acting as plant growth promoters.

    The following article shows the evolution of the schools contribution to the Health Education of children and young people. Moving on from the traditional concept of health, today, Health Education has a general and global meaning, which encompasses all of the physical, psychological and social aspects of health. These aspects define the characteristics of the "Healthy School". The need to broach the "transversal subject" offers schools the possibility of developing "transversality" in the Health Education. Finally, the concept of promoting health defines, together with the other subjects, that which we understand by "the heath promotion schools", which attempts to progress the full integration of schools in the society in which they are located.

  7. Discrete model for DNA-promoter dynamics

    NASA Astrophysics Data System (ADS)

    Salerno, Mario

    1991-10-01

    We introduce a discrete model for DNA that takes into account the information about specific base sequences along the double helix. We use this model to study nonlinear wave dynamics of the T7A1 DNA promoter. As results we show the existence in the promoter of a dynamically active region in which static solitons acquire finite velocities, which contrasts with regions where solitons simply remain static. Furthermore, when they pass through this region moving solitons are accelerated, decelerated, or reflected, depending on their initial velocities. The possibility that these dynamical effects play a role in the mechanism of genetic activation is suggested.

    This article is an overview of the promotion function as a part of the ATM's marketing mix. It approaches various promotion decision areas from a managerial perspective, focusing upon some key components of promotion planning. Rather than provide specific operational or implementation details (how to write a brochure) it is more conceptual in nature and offers a framework for promotion planners. The article addresses promotion management, promotion objectives, analysis for promotion planning, the promotion mix, and addresses the benefits and limitations of some specific promotion tools available to the ATM manager. It treats ATMs as a service and reveals specific implications for promotion strategy dictated by services. The article also reports promotion tools employed by Alabama ATMs citing data from the Alabama study.

    PubMed Central

    Hoffmann, D; Hecht, S S; Wynder, E L

    1983-01-01

    Cigarette smoke induces carcinoma of the larynx in Syrian golden hamsters and is active as a tumor promoter in hamsters pretreated with a low dose of a PAH, nitrosamine, or nitrosamide. These tumorigenic effects are only observed with total smoke, but not with the gas phase alone. This demonstrates that the tumorigenic agents reside primarily in the particulate phase. According to fractionation experiments, a number of four- and five-ring aromatic hydrocarbons serve as the major tumor initiators in tobacco smoke. Tumor promoters reside primarily in weakly polaric neutral subfractions and in the weakly acidic portion of the particulate matter and include certain unsaturated hydrocarbons and phenolic compounds. Cocarcinogenic activity is a characteristic feature of tobacco smoke and its particulates. Among the cocarcinogens formed during combustion are catechols and certain nontumorigenic aromatic hydrocarbons and terpenes. Nicotine may also serve as a cocarcinogen as is indicated by preliminary data. The action of tumor promoters and cocarcinogens in tobacco carcinogenesis, the precursors for tobacco smoke promoters and cocarcinogens, and methods for their reduction in smoke are discussed.

    Kolip, P

    2008-01-01

    Numerous gender differences in health-related behaviour are relevant in the planning of health promotion and prevention. More men than women consume amounts of alcohol that are a risk to their health. Tobacco consumption has fallen slightly among men but has risen among women. Women eat more healthy food. Man behave risky in leisure time and traffic, thus their mortality rates due to accidents are much higher, especially in young age groups. The epidemiological data lead to the conclusion that gender sensitive health promotion and prevention is necessary. Gender mainstreaming is declared as the main strategy to enhance gender equity in health. The paper focuses on the public health action cycle and demonstrates that at each step gender mainstreaming improves the quality of intervention. To implement gender mainstreaming in health promotion and prevention, a process of sensitization has to be initialized. An instrument is presented that supports this process at the foundation "Health Promotion Switzerland". A short description of some examples of gender adequate interventions is given at the end of the paper.

  16. Pleiotrophin promotes perineural invasion in pancreatic cancer.

    PubMed

    Yao, Jun; Hu, Xiu-Feng; Feng, Xiao-Shan; Gao, She-Gan

    2013-10-21

    Perineural invasion (PNI) in pancreatic cancer is an important cause of local recurrence, but little is known about its mechanism. Pleiotrophin (PTN) is an important neurotrophic factor. It is of interest that our recent experimental data showed its involvement in PNI of pancreatic cancer. PTN strongly presents in the cytoplasm of pancreatic cancer cells, and high expression of PTN and its receptor may contribute to the high PNI of pancreatic cancer. Correspondingly, PNI is prone to happen in PTN-positive tumors. We thus hypothesize that, as a neurite growth-promoting factor, PTN may promote PNI in pancreatic cancer. PTN is released at the time of tumor cell necrosis, and binds with its high-affinity receptor, N-syndecan on pancreatic nerves, to promote neural growth in pancreatic cancer. Furthermore, neural destruction leads to a distorted neural homeostasis. Neurons and Schwann cells produce more N-syndecan in an effort to repair the pancreatic nerves. However, the abundance of N-syndecan attracts further PTN-positive cancer cells to the site of injury, creating a vicious cycle. Ultimately, increased PTN and N-syndecan levels, due to the continuous nerve injury, may promote cancer invasion and propagation along the neural structures. Therefore, it is meaningful to discuss the relationship between PTN/N-syndecan signaling and PNI in pancreatic cancer, which may lead to a better understanding of the mechanism of PNI in pancreatic cancer.

  8. Health promotion and health for all.

    PubMed

    Samiel, S

    2000-01-01

    The recognition that health is intimately related to economic status, education, physical living conditions, culture, history, issues of gender and human rights, the level of peace and safety, and the life people live, is not entirely new. The health sector has been making its way towards this position for a very long time. The literature describes recognition of the connection between living conditions and health status from the early 19th century. To ensure that people live in societies that create health, there is a need to first recognize the following: that there are multiple and diverse forces within society which create or undermine health; and that most of the factors which are essential for a healthy community reside outside the formal health sector. Action to create healthy societies with healthy people then must tap multiple power sources and involve broad collaboration and alliances. The health promotion strategies of the Caribbean Health Promotion Charter and the Ottawa Charter are outlined. Some of these strategies include the establishment of public policies on health, creation of supportive environments, empowerment of communities through community action, promotion of personal health skills, reorientation of health services, and the need to create alliances. The health promotion is an approach, which respects people's rights to healthy living and is based on the recognition that health is the result of an interconnection between all aspects of life. The strategy can best be achieved through full participation of the various sectors, interest groups and communities in a society.

    Harry Misuriello; DOE Project Officer - Keith Bennett

    2006-01-25

    The Department of Energy funded the Alliance to Save Energy to promote the efficient use of energy under a multiyear cooperative agreement. This funding allowed the Alliance to be innovative and flexible in its program development, and to initiate and enhance projects it would otherwise not have been able to pursue. The program period was 1999 through 2004. The mission of the Alliance to Save Energy is to promote energy efficiency domestically and worldwide. The Alliance followed this mission by working closely with consumers, government, policy makers, and energy efficient product and service providers. The projects that were initiated by the Alliance included communication and consumer education, policy analysis and research, the promotion of interaction among the energy efficiency industry, and international energy efficiency programs. The funding from the Department of Energy allowed the Alliance to study new issues in energy efficiency, draw public attention to those issues, and create targeted programs, such as the Efficient Windows Collaborative or the Green Schools program, which now function on their own to promote energy efficiency in important areas.

  6. Pertussis toxin promoter sequences involved in modulation.

    PubMed Central

    Gross, R; Rappuoli, R

    1989-01-01

    Previous analysis of the pertussis toxin (PT) promoter has shown that expression of PT requires a trans-activating factor encoded by the vir locus and a 170-base-pair DNA sequence upstream from the transcription start site containing a 21-base-pair direct repeat sequence crucial trans-activation (R. Gross and R. Rappuoli, Proc. Natl. Acad. Sci. USA 85:3913-3917, 1988). In this paper we extend the analysis to the modulative response to environmental stimuli. We show that modulation acts at the transcriptional level and occurs only in phase I bacteria. Modulation also requires a functional vir locus and the same promoter region of 170 base pairs. We show that, in addition to the previously identified direct repeat, even the sequences downstream from position -117 are required for trans-activation and modulation and that the deletion of four cytosine residues at position -31 causes the inactivation of the promoter. The kinetics of the change in transcription show that the PT promoter can be shut off very rapidly by adding 50 mM MgSO4 to the medium, whereas resumption of transcription after removal of the modulative agents from the medium is slow.

    Enterprises have put more and more emphasis on data analysis so as to obtain effective management advices. Managers and researchers are trying to dig out the major factors that lead to employees' promotion and resignation. Most previous analyses are based on questionnaire survey, which usually consists of a small fraction of samples and contains biases caused by psychological defense. In this paper, we successfully collect a data set consisting of all the employees' work-related interactions (action network, AN for short) and online social connections (social network, SN for short) of a company, which inspires us to reveal the correlations between structural features and employees' career development, namely promotion and resignation. Through statistical analysis, we show that the structural features of both AN and SN are correlated and predictive to employees' promotion and resignation, and the AN has higher correlation and predictability. More specifically, the in-degree in AN is the most relevant indicator for promotion, while the k-shell index in AN and in-degree in SN are both very predictive to resignation. Our results provide a novel and actionable understanding of enterprise management and suggest that to enhance the interplays among employees, no matter work-related or social interplays, can be helpful to reduce staffs' turnover risk.

    Extracellular histones promote platelet aggregation and thrombosis; this is followed by induction of coagulation disorder, which results in exhaustion of coagulation factors. Complement component 5 (C5) is known to be associated with platelet aggregation and coagulation system activation. To date, the pathological mechanism underlying liver injury has remained unclear. Here, we investigated whether C5 promotes liver injury associated with histone-induced lethal thrombosis. C5-sufficient and C5-deficient mice received single tail vein injections of purified, unfractionated histones obtained from calf thymus (45–75 μg/g). Subsequently, the mice were monitored for survival for up to 72 h. Based on the survival data, the 45 μg/g dose was used for analysis of blood cell count, liver function, blood coagulation ability, and promotion of platelet aggregation and platelet/leukocyte aggregate (PLA) production by extracellular histones. C5-deficient mice were protected from lethal thrombosis and had milder thrombocytopenia, consumptive coagulopathy, and liver injury with embolism and lower PLA production than C5-sufficient mice. These results indicate that C5 is associated with coagulation disorders, PLA production, and embolism-induced liver injury. In conclusion, C5 promotes liver injury associated with histone-induced lethal thrombosis. PMID:28205538

    1983-01-01

    A survey of California employers with more than 100 employees at one or more sites was undertaken to determine: 1) the nature and extent of health promotion activities; 2) plans for continuation and/or expansion of these activities; 3) plans for initiation of new activities; and 4) the relationship between reported health promotion activities and other characteristics of employers. Of 511 employers with whom interviews were attempted, 49 possible respondents could not be reached and 38 respondents refused to be interviewed, leaving 424 or 83 per cent. Almost one-half of the sites where interviews were conducted had fewer than 200 employees. A total of 332 (78.3 per cent) of employers offered one or more health promotion activities. The most frequent activities provided were accident prevention (64.9 per cent) and CPR (52.8 per cent) with other frequent programs including alcohol/drug abuse (18.6 per cent), mental health counseling (18.4 per cent), stress management (13.0 per cent), fitness (11.6 per cent), hypertension screening (10.1 per cent), and smoking cessation (8.3 per cent). Employers with at least one activity averaged 2.8 activities. The likelihood of having health promotion activities increased with company size. Establishment of new programs appeared to accelerate rapidly in recent years. PMID:6837818

  6. Characteristics of a strong promoter from figwort mosaic virus: comparison with the analogous 35S promoter from cauliflower mosaic virus and the regulated mannopine synthase promoter.

    PubMed

    Sanger, M; Daubert, S; Goodman, R M

    1990-03-01

    A segment of DNA from the genome of figwort mosaic virus (FMV) strain M3 possesses promoter activity when tested in electroporated protoplasts from, and transgenic plants of, Nicotiana tabacum cv. Xanthi nc. The 1.1 kb DNA segment, designated the '34S' promoter, is derived from a position on the FMV genome comparable to the position on the cauliflower mosaic virus (CaMV) genome containing the 35S promoter. The 34S and 35S promoters show approximately 63% nucleotide homology in the TATA, CCACT, and -18 to +1 domains, but in sequences further upstream the homology drops below 50%. Promoter activities were estimated using beta-glucuronidase and neomycin phosphotransferase II reporter gene systems. The activity of the 34S promoter segment approximates that of the 35S promoter in both protoplast transient expression assays and in stably transformed tobacco plants. Truncation of 5' sequences from the 34S promoter indicates that promoter strength depends upon DNA sequences located several hundred nucleotides upstream from the TATA box. In leaf tissue the 34S promoter is 20-fold more active than the mannopine synthase (MAS) promoter from Agrobacterium tumefaciens T-DNA. The 34S promoter lacks the root-specific and wound-stimulated expression of the MAS promoter, showing relatively uniform root, stem, leaf, and floral activities.

    2016-03-01

    Since 1990, the WHO Health Promoting Hospital (HPH) movement has tried to facilitate and support hospitals to assume a core responsibility in health promotion. The Taiwan HPH Network was established in December 2006, and became the largest HPH network in the world in 2013. Compared to Europe where the HPH has been more established, the pace of HPH development has been much more rapid. This rapid development provides an inspiring example for research and health promotion practice. Systematic data and empirical information have been collected about HPH in Taiwan, allowing for research to be published about the achievements of the HPH movement. This paper provides an overview of the existing literature on current progress of the HPH project according to the four main perspectives of the WHO-HPH movement: promoting the health of patients, promoting the health of staff, changing the organization to a health-promoting setting, and promoting the health of the community in the catchment area of the hospital. The assessment can serve as a stepping stone in understanding current HPH development in Taiwan and as a reference for future research.

    Attention must be redirected toward health promotion as nursing evaluates the goal of health for all. Confusion regarding health promotion behavior is illustrated by terms with diverse meanings and uses. In a process of critical analysis, five multidisciplinary experts in health promotion responded to a survey targeting the distinction of health promotion, health promotion behavior, health protection behavior, disease prevention behavior, preventive health behavior, health behavior, and healthy lifestyle. Descriptors of health promotion were derived from a multidimensional conception of well-being. Disagreement existed concerning health protection and health behavior. Nursing interventions are linked to reflective discourse regarding health promotion behavior.

  15. In trans promoter activation by enhancers in transient transfection.

    PubMed

    Smirnov, N A; Akopov, S B; Didych, D A; Nikolaev, L G

    2017-03-01

    Earlier, it was reported that the strong cytomegalovirus enhancer can activate the cytomegalovirus promoter in trans, i.e. as a separate plasmid co-transfected with a promoter-reporter gene construct. Here we demonstrate that the ability of enhancers to activate promoters in trans in transient transfection experiments is a property of not only viral regulatory elements but also of various genomic enhancers and promoters. Enhancer-promoter activation in trans is promoter- and cell type-specific, and accompanied by physical interaction between promoter and enhancer as revealed by chromosome conformation capture assays. Thus, promoter activation in transient co-transfection of promoters and enhancers shares a number of important traits with long-distance promoter activation by enhancers in living cells and may therefore serve as a model of this fundamental cellular process.

    PubMed Central

    Slaga, T. J.; Fischer, S. M.; Nelson, K.; Gleason, G. L.

    1980-01-01

    The effects of nonpromoting and weakly promoting diterpenes on skin tumor promotion by 12-O-tetradecanoylphorbol 13-acetate (TPA) were investigated. When phorbol and phorbol 12,13-diacetate (both nonpromoting) were given simultaneously with TPA after 7,12-dimethylbenz[a]-anthracene (DMBA) initiation in female mice, they had no effect on TPA promotion. However, the nonpromoter 4-O-methyl-TPA and the weak promoter mezerein were found to inhibit TPA promotion in a dose-dependent manner when given simultaneously with TPA. Because mezerein was found to be an effective inhibitor of TPA promotion when given simultaneously and because it induces many biological responses similar to those to TPA, the capacity of mezerein to act as an incomplete promoter in a two-stage promotion protocol was also investigated. Twice-weekly applications of 1,2, or 5 μg of TPA for 2 weeks after DMBA initiation produced 0, 0, and 0.5 papilloma per mouse, respectively, at 20 weeks. When the twice-weekly applications of TPA for 2 weeks were followed by twice-weekly treatments with 2 μg of mezerein for 18 weeks, the number of papillomas per mouse was 2.2, 3.5, and 9.0, respectively. Twice-weekly applications of 2 μg of TPA for 2 weeks followed by twice-weekly treatments with 1, 2, or 4 μg of mezerein for 18 weeks produced 2.1, 3.5, and 6.8 papillomas per mouse, respectively, in DMBA-treated mice. Twice-weekly doses as high as 40 μg of 4-O-methyl-TPA were not effective in producing tumors when given after a limited treatment with TPA; however, 4-O-methyl-TPA had weak activity as a first-stage promoter. The results suggest that although mezerein by itself is a weak promoter and mimics TPA in many biochemical and morphological effects it is a potent second-stage promoter in a two-stage promotion regimen.

    Background Diarrhoea accounts for 1.8 million deaths in children in low- and middle-income countries (LMICs). One of the identified strategies to prevent diarrhoea is hand washing. Objectives To assess the effects of hand washing promotion interventions on diarrhoeal episodes in children and adults. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register (27 May 2015); CENTRAL (published in the Cochrane Library 2015, Issue 5); MEDLINE (1966 to 27 May 2015); EMBASE (1974 to 27 May 2015); LILACS (1982 to 27 May 2015); PsycINFO (1967 to 27 May 2015); Science Citation Index and Social Science Citation Index (1981 to 27 May 2015); ERIC (1966 to 27 May 2015); SPECTR (2000 to 27 May 2015); Bibliomap (1990 to 27 May 2015); RoRe, The Grey Literature (2002 to 27 May 2015); World Health Organization (WHO) International Clinical Trial Registry Platform (ICTRP), metaRegister of Controlled Trials (mRCT), and reference lists of articles up to 27 May 2015. We also contacted researchers and organizations in the field. Selection criteria Individually randomized controlled trials (RCTs) and cluster-RCTs that compared the effects of hand washing interventions on diarrhoea episodes in children and adults with no intervention. Data collection and analysis Three review authors independently assessed trial eligibility, extracted data, and assessed risk of bias. We stratified the analyses for child day-care centres or schools, community, and hospital-based settings. Where appropriate, incidence rate ratios (IRR) were pooled using the generic inverse variance method and random-effects model with 95% confidence intervals (CIs). We used the GRADE approach to assess the quality of evidence. Main results We included 22 RCTs: 12 trials from child day-care centres or schools in mainly high-income countries (54,006 participants), nine community-based trials in LMICs (15,303 participants), and one hospital-based trial among people with acquired immune deficiency

    1996-06-01

    A marine cyanobacterial promoter was cloned to allow efficient foreign gene expression. This was carried out using chloramphenicol acetyl transferase (CAT) as a marker protein. For rapid and simple measurement of CAT activity, a method based on a fluorescently labeled substrate was improved by utilizing HPLC equipped with a flow-through fluorescent spectrophotometer. This method was used in conjunction with a newly constructed promoter probe vector. Cyanobacterial transformants, harboring plasmid containing a cloned 2-kbp marine cyanobacterial genomic fragment, showed a 10-fold higher CAT activity, compared with that achieved using the kanamycin-resistant gene promoter. From the sequence analysis of the cloned fragment, a putative promoter region was found. 20 refs., 7 figs., 2 tabs.

    2006-01-01

    The energy of interaction between DNA strands in promoters is of great functional importance. Visualization of the energy of DNA strands distribution in promoter sequences was achieved. The separation of promoters in groups by their energetic properties enables evaluation of the dependence of promoter strength on the energetic properties. The analysis of groups (clusters) of promoters distributed by the energy of DNA strands interaction in −55, −35, −10 and +6 sequences indicates their connection with the transcriptional activity.

    1991-10-01

    Praziquantel, the widely used anti-helminthic agent, was investigated for hepatocarcinogenesis-promoting potential using a medium-term liver bioassay system for carcinogens. F344 male rats were given a single intraperitoneal injection of diethylnitrosamine (DEN, 200 mg/kg) and then starting 2 weeks later, received praziquantel in the diet at concentrations of 1.5 or 0.5%, or intragastrically at a dose of 1,500 mg/kg once a week for 6 weeks. Control groups received DEN or praziquantel alone. All rats were subjected to two-thirds partial hepatectomy at week 3 and killed at week 8. Development of glutathione S-transferase placental form-positive foci in the liver was significantly increased in terms of both number and area with the 1.5% dose, while only area was affected by the 0.5% dose. The results thus indicate that praziquantel at high dose has promoting potential in rat hepatocytic tumorigenesis.

    2015-01-01

    Summary Apoptosis is typically considered an anti-oncogenic process since caspase activation can promote the elimination of genetically unstable or damaged cells. We report that a central effector of apoptosis, caspase 3, facilitates, rather than suppresses, chemical and radiation-induced genetic instability and carcinogenesis. We found that a significant fraction of mammalian cells treated with ionizing radiation can survive, despite caspase 3 activation. Moreover, this sublethal activation of caspase 3 promoted persistent DNA damage and oncogenic transformation. In addition, chemically-induced skin carcinogenesis was significantly reduced in mice genetically deficient in caspase 3. Furthermore, attenuation of Endo G activity significantly reduced radiation-induced DNA damage and oncogenic transformation, identifying Endo G as a downstream effector of caspase 3 in this pathway. Our findings suggest that rather than acting as a broad inhibitor of carcinogenesis, caspase 3 activation may contribute to genome instability and play a pivotal role in tumor formation following damage.

    2016-01-01

    Despite evidence that physical activity reduces the risk of falls and other causes of disability and death, the majority of older adults do not engage in physical activity on a regular basis. Mobile technology applications have emerged as potential resources for promoting physical activity behavior. This article describes features of a new application, Ready~Steady, highlighting approaches used in its design and development, and implications for clinical practice. Iterative processes enabled the design, development, implementation, and evaluation of the application consistent with the wellness motivation theory, as well as established user-specific strategies and theoretical design principles. Implications in terms of potential benefits and constraints are discussed. Integrating technology that promotes health and wellness in the form of mobile computer applications is a promising adjunct to nursing practice. PMID:23463915

  6. Food for creativity: tyrosine promotes deep thinking.

    PubMed

    Colzato, Lorenza S; de Haan, Annelies M; Hommel, Bernhard

    2015-09-01

    Anecdotal evidence suggests that creative people sometimes use food to overcome mental blocks and lack of inspiration, but empirical support for this possibility is still lacking. In this study, we investigated whether creativity in convergent- and divergent-thinking tasks is promoted by the food supplement L-Tyrosine (TYR)-a biochemical precursor of dopamine, which is assumed to drive cognitive control and creativity. We found no evidence for an impact of TYR on divergent thinking ("brainstorming") but it did promote convergent ("deep") thinking. As convergent thinking arguably requires more cognitive top-down control, this finding suggests that TYR can facilitate control-hungry creative operations. Hence, the food we eat may affect the way we think.

    Differentiation of myoblasts is essential in the development and regeneration of skeletal muscles to form multinucleated, contractile muscle fibers. However, the process of myoblast differentiation in mammals is complicated and requires to be further investigated. In this study, we found Palmdelphin (Palmd), a cytosolic protein, promotes myoblast differentiation. Palmd is predominantly expressed in the cytosol of myoblasts and is gradually up-regulated after differentiation. Knockdown of Palmd by small interfering RNA (siRNA) in C2C12 markedly inhibits myogenic differentiation, suggesting a specific role of Palmd in the morphological changes of myoblast differentiation program. Overexpression of Palmd in C2C12 enhances myogenic differentiation. Remarkably, inhibition of Palmd results in impaired myotube formation during muscle regeneration after injury. These findings reveal a new cytosolic protein that promotes mammalian myoblast differentiation and provide new insights into the molecular regulation of muscle formation. PMID:28148961

    The aim of this study was to analyze national and international scientific literature on nursing care for lesbian women. An integrative approach was adopted to review studies from MEDLINE, LILACS, BDENF and SCOPUS databases and SciELO and Cochrane libraries using the keywords: female homosexuality, nursing care, health promotion and women's health. Studies published between 1990 and 2013 in English, Portuguese or Spanish were considered for analysis. After analyzing data, four international studies were selected, being that three were from the United States and one was from Canada. This study revealed a scarcity of Brazilian and international studies and the importance of increasing scientific literature on this topic. Descriptors: Homosexuality, female. Nursing care. Health promotion. Women's health.

  9. National news. Indonesia. Promoting ARH awareness.

    Limited availability of IEC materials is hindering efforts to promote adolescent reproductive health in Indonesia. This, in turn, reflects a lack of awareness on the part of policy makers and community leaders about the importance of interventions directed at young people. Two ongoing United Nations Population Fund projects seek to promote awareness of adolescent reproductive health needs in Jakarta, Yogyakarta, West Java, Bali, Lampung, and Riau. A coalition of governmental and nongovernmental agencies has been established to implement the project. By project end in 1999, government agencies and nongovernmental organizations are expected to have incorporated youth-oriented activities into their overall programming and formulated relevant policy guidelines. Another project (Strengthening Strategies to Improve Adolescent Reproductive Health through Materials Development), implemented by the Indonesian Planned Parenthood Association, is focusing on the development and distribution of reproductive health materials for specific target audiences.

  10. Health promotion by social cognitive means.

    PubMed

    Bandura, Albert

    2004-04-01

    This article examines health promotion and disease prevention from the perspective of social cognitive theory. This theory posits a multifaceted causal structure in which self-efficacy beliefs operate together with goals, outcome expectations, and perceived environmental impediments and facilitators in the regulation of human motivation, behavior, and well-being. Belief in one's efficacy to exercise control is a common pathway through which psychosocial influences affect health functioning. This core belief affects each of the basic processes of personal change--whether people even consider changing their health habits, whether they mobilize the motivation and perseverance needed to succeed should they do so, their ability to recover from setbacks and relapses, and how well they maintain the habit changes they have achieved. Human health is a social matter, not just an individual one. A comprehensive approach to health promotion also requires changing the practices of social systems that have widespread effects on human health.

    Studies on the relation between health and work tend to highlight the negative and pathological aspects, as if work produces only sickness and alienation. On the contrary, our proposal is to stress how work can also produce health. Based on Canguillem's concept of health, and from the contributions of the so-called "work clinics", we intend to analyze the purpose of work as a promoter of health. Canguilhem affirms that health is not adaptive, as such it does not involve adapting well to the world, but to the creation of tenets of life. For their part, the work clinics provide tools to approximate us to the know-how-to-do produced by workers in their daily work, namely not only how workers adapt to work, but how they create and recreate it permanently Thus, we can think work as a promoter of health where there is room for collective and personal creation, as well as recognition of workers in their activity.

    Promoted combustion testing of metallic materials has been performed by NASA since the mid-1980s to determine the burn resistance of materials in oxygen-enriched environments. As the technolo gy has advanced, the method of interpreting, presenting, and applying the promoted combustion data has advanced as well. Recently NASA changed the bum criterion from 15 cm (6 in.) to 3 cm (1.2 in.). This new burn criterion was adopted for ASTM G 124, Standard Test Method for Determining the Combustion Behavior- of Metallic Materials in Oxygen-Enriched Atmospheres. Its effect on the test data and the latest method to display the test data will be discussed. Two specific examples that illustrate how this new criterion affects the burn/no-bum thresholds of metal alloys will also be presented.

  13. Promoting proximal formative assessment with relational discourse

    The practice of proximal formative assessment - the continual, responsive attention to students' developing understanding as it is expressed in real time - depends on students' sharing their ideas with instructors and on teachers' attending to them. Rogerian psychology presents an account of the conditions under which proximal formative assessment may be promoted or inhibited: (1) Normal classroom conditions, characterized by evaluation and attention to learning targets, may present threats to students' sense of their own competence and value, causing them to conceal their ideas and reducing the potential for proximal formative assessment. (2) In contrast, discourse patterns characterized by positive anticipation and attention to learner ideas increase the potential for proximal formative assessment and promote self-directed learning. We present an analysis methodology based on these principles and demonstrate its utility for understanding episodes of university physics instruction.

    Despite evidence that physical activity reduces the risk of falls and other causes of disability and death, the majority of older adults do not engage in physical activity on a regular basis. Mobile technology applications have emerged as potential resources for promoting physical activity behavior. This article describes features of a new application, Ready∼Steady, highlighting approaches used in its design and development, and implications for clinical practice. Iterative processes enabled the design, development, implementation, and evaluation of the application consistent with the wellness motivation theory, as well as established user-specific strategies and theoretical design principles. Implications in terms of potential benefits and constraints are discussed. Integrating technology that promotes health and wellness in the form of mobile computer applications is a promising adjunct to nursing practice.

    This commentary discusses pertinent issues from Hyosun Kim’s paper on online prescription drug promotion. The study is well-designed and the findings highlight some of the consequences of the Food and Drug Administration’s (FDA’s) decision to deregulate online advertising of prescription drugs. While Kim’s findings confirm some of the early concerns, they also provide a perspective of implementation challenges in the ever-changing technological environment. PMID:27285519

    In promoting greater public awareness of nurse practitioners' contributions to health care, two major strategies may be used. Creating broad-based visibility through the use of the basic media and marketing strategies, and utilizing individual client encounters to educate clients about the NP role are both effective. NPs should assume the initiative in seeking out opportunities to create positive images for the nurse practitioner.

    Why are there national differences in the propensity to bribe? To investigate this question, we conducted a correlational study with cross-national data and a laboratory experiment. We found a significant effect of the degree of collectivism versus individualism present in a national culture on the propensity to offer bribes to international business partners. Furthermore, the effect was mediated by individuals' sense of responsibility for their actions. Together, these results suggest that collectivism promotes bribery through lower perceived responsibility for one's actions.

    The National Science Foundation and others conclude that institutional transformation is required to ensure equal opportunities for the participation and advancement of men and women in academic science, technology, engineering, mathematics, and medicine (STEMM). Such transformation requires changing the habitual attitudes and behaviors of faculty. Approaching implicit bias as a remediable habit, we present the theoretical basis and conceptual model underpinning an educational intervention to promote bias literacy among university faculty as a step toward institutional transformation regarding gender equity. We describe the development and implementation of a Bias Literacy Workshop in detail so others can replicate or adapt it to their setting. Of the 220 (167 faculty and 53 nonfaculty) attendees from the initial 17 departments/divisions offered this workshop, all 180 who completed a written evaluation found the workshop at least "somewhat useful" and 74% found it "very useful." Over 68% indicated increased knowledge of the workshop material. Of the 186 participants who wrote a commitment to engage in new activities to promote gender equity, 87% incorporated specific workshop content. Twenty-four participants were interviewed 4-6 months after attending the workshop; 75% of these not only demonstrated increased bias awareness, but described plans to change-or had actually changed-behaviors because of the workshop. Based on our sample of faculty from a Midwestern university, we conclude that at least one third of STEMM faculty who are invited will attend a 2.5-hr Bias Literacy Workshop, that nearly all will find it useful, and that most will complete a written commitment to promoting gender equity. These findings suggest that this educational intervention may effectively promote institutional change regarding gender equity.
