Influence du porte-greffe sur le comportement du cépage Gamaret dans le vignoble tessinois

Le Gamaret, un cepage rouge obtenu en 1970 au centre de recherche Pully d’Agroscope a partir d’un croisement entre Gamay et Reichensteiner, a commence a etre diffuse dans le vignoble suisse des 1990 (Spring et Maigre 1995; Spring 2004; Dupraz et Spring 2010). Son aptitude a fournir des vins de haute qualite, structures et riches en composes phenoliques ainsi que ses qualites culturales, comme son excellente resistance a la pourriture du raisin (Botrytis cinerea) (Pezet 1993), expliquent son rapide developpement dans le vignoble suisse (fig.1). Pendant une dizaine d’annees, le Gamaret a ete le cepage le plus plante en Suisse. En 2011, la surface des vignes de Gamaret en production avoisinait 400 ha, le placant ainsi au quatrieme rang des cepages rouges derriere le Pinot noir, le Gamay et le Merlot et devant le Garanoir (OFAG 2012). A la suite d’essais conduits dans le vignoble du Beaujolais, le Gamaret a egalement ete introduit dans le catalogue francais des cepages autorises en 2010. Dans notre pays, son extension s’est avant tout marquee en Suisse romande (VD, GE, VS). En raison de sa relative plasticite d’adaptation, il a aussi ete teste dans les domaines experimentaux Influence du porte-greffe sur le comportement du cepage Gamaret dans le vignoble tessinois
Delivery of hyper‐interleukin‐6 to the injured spinal cord increases neutrophil and macrophage infiltration and inhibits axonal growth

Cytokine growth factors of the interleukin (IL)–6 family have recently been shown to play an important role in central nervous system (CNS) development, repair, and inflammation. These cytokines, which interact via specific membrane receptors, share a signal‐transducing receptor subunit, glycoprotein 130 (gp130). Gp130 is expressed by motoneurons in the gray matter of the rat spinal cord and by several brainstem nuclei that project to the spinal cord including the red, reticular, and vestibular nuclei. In this study, we examined whether stimulation of gp130 signaling, with the use of grafts of fibroblasts genetically modified to deliver the fusion protein, hyper‐IL‐6 (H‐IL‐6), which consists of the cytokine growth factor, IL‐6, and its α receptor, would elicit growth of injured spinal cord axons. Particular emphasis was placed on examining the potentially competing effects of growth factor versus proinflammatory influences of H‐IL‐6 in the context of spinal cord injury. Our results demonstrated that grafts delivering H‐IL‐6 induce a sixfold increase in the number of neutrophils (P < 0.05) and a twofold increase in the areas of spinal tissue occupied by macrophages and activated microglia (P < 0.01) at the site of the spinal cord injury when compared with control grafts. Of note, this augmentation in inflammatory cell infiltration correlated with a significant twofold increase in lesion size (P < 0.05) and a fourfold reduction in axonal growth (P < 0.01) at the lesion site. Thus, potential neurotrophic properties of this cytokine family of growth factors must be balanced against their inflammatory properties when considering therapeutic application to CNS injury. J.

Health Promotion Outcomes of a Newly Developed Elastic Band Exercise Program for Older Adults in the Community: A Pilot Test

Background: Studies indicate that the incidence of disease, the mortality rate, and medical costs are significantly higher in people aged 65 years and over who do not engage in physical activities than in their peers who do engage in these activities. Therefore, promoting appropriate physical activity among older adults in the community is essential to delaying the health implications of aging. Purpose: This pilot test was developed to assess the effectiveness of a newly developed Senior Elastic Band (SEB) exercise program on the health of older adults in community care stations. Methods: A quasiexperimental design was used. A convenience sample of 20 participants from a community care station was recruited. The SEB intervention included three phases (warm-up, aerobic motion, and static stretching) and was conducted three times per week, 40 minutes per session for 1 month. Twelve health indicators in three categories (functional fitness, self-perceived health status, and sleep quality) were examined before and immediately after 1 month of SEB exercises. Results: Participants showed improved performance at the end of the 1-month study for the following indicators: lung capacity, cardiopulmonary fitness, upper and lower body flexibilities, upper limb muscle power, lower limb muscle endurance, and self-perceived physical health status (all ps < .05). No significant differences were identified for the other indicators. Conclusions/Implications for Practice: The SEB exercise program shows preliminary and promising effects on improving the health of older adults in a community care station. Healthcare professionals who work with older adults living in the community may consider the SEB exercise program as a health promotion modality to recommend and implement with this population. However, we recommend further testing the long-term effects of this program on a larger population.
Dietary Consumption Triggers in Interstitial Cystitis/Bladder Pain Syndrome Patients

Objectives: The aim of this study was to survey interstitial cystitis/bladder pain syndrome (IC/BPS) patients with a Web-based questionnaire to determine which consumables (foods, drinks, supplements/spices, and general food categories) truly exacerbate IC/BPS symptoms. Methods: The Interstitial Cystitis Association posted a Web link on its Web site offering its members participation in the Web-based questionnaire from April 2009 to February 2010. Members were asked questions on the effect of 344 different foods, drinks, supplements, condiments/spices, and general food categories on urinary frequency, urgency, and/or pelvic pain symptoms. Members were asked to score symptoms related to consumables on a symptom Likert scale of 0 to 5. Questions on ethnicity, education, symptom duration, seasonal allergies, irritable bowel syndrome, and specific diets were included. Results: There were 598 complete responses to the questionnaire, and 95.8% of the participants answered that certain foods and beverages affected their IC/BPS symptoms. Most items had no effect on symptoms. Items that made symptoms worse were citrus fruits, tomatoes, coffee, tea, carbonated and alcoholic beverages, spicy foods, artificial sweeteners, and vitamin C. Only calcium glycerophosphate (Prelief; AK Pharma, Inc, Pleasantville, NJ) and sodium bicarbonate (baking soda) had a trend toward improvement in symptoms. Conclusions: Interstitial cystitis diets do not have to be overly restrictive. It is recommended that patients with IC/BPS avoid citrus fruits, tomatoes, coffee, tea, carbonated and alcoholic beverages, spicy foods, artificial sweeteners, and vitamin C. The use of calcium glycerophosphate and/or sodium bicarbonate before consumption of these trigger consumables may also help reduce sensitivity.
A Double‐Blind, Multiple‐Dose, Placebo‐Controlled, Cross‐Over Study to Compare the Incidence of Gastrointestinal Complaints in Healthy Subjects Given Doryx R and Vibramycin R

Ninety‐eight healthy subjects completed a double‐blind, placebo‐controlled, multiple‐dose cross‐over study to compare the incidence of gastrointestinal side effects of Doryx (Parke‐Davis, Morris Plains, NJ) capsules (enteric‐coated doxycycline hyclate pellets) and Vibramycin (Pfizer, New York, NY) capsules (doxycycline hyclate powder). Doryx produced statistically significantly fewer episodes of nausea, vomiting, stomach of abdominal discomfort, and decreased appetite than did Vibramycin. For every symptom, Vibramycin produced statistically significantly more symptom reports than did placebo. Although Doryx produced significantly more reports of nausea than did placebo, there was no significant difference for the other symptoms. Based on these results, Doryx is superior to Vibramycin when considering the incidence of gastrointestinal side effects.
Prevalence of HSV-2 antibodies among STD clinic patients in Tanzania

Summary: Patients attending a referral sexually transmissible diseases clinic at Muhimbili Medical Centre in Dar-es-Salaam during the period 1989 to 1993 were examined for herpes simplex virus type 2 (HSV-2) antibodies. An ELISA technique, using glycoprotein G of HSV-2 as antigen, was used to test 294 patients' sera. Of these, 126 sera were HSV-2 positive, while 168 were negative, yielding an overall HSV-2 prevalence of 42.9%. Sixty-three per cent of the women and 35.5% of the men were HSV-2 positive. Seropositivity rose from 8.7% in the youngest men to 61.5% in the oldest male age group, while even the youngest women aged 20 or less had an HSV-2 prevalence of 55.6%. There was a significant positive association between HIV and HSV-2 seropositivity ( P =0.0006), most pronounced among the youngest women. There was no over-representation of HSV-2 positivity among patients with genital ulcer disease, indicating that other causes of this disease could be more common than HSV-2 in Tanzania.
Plasma immunoreactive neuropeptide Y in congestive heart failure at rest and during exercise.

The purpose of the study described here was to study plasma immunoreactive Neuropeptide Y (NPY) at rest and during exercise in patients with congestive heart failure (CHF) and in healthy subjects. Thirty-five patients, mean age 64 years, with CHF in optimal treatment and with a mean ejection fraction of 32%, were studied at rest and during exercise. Twelve age and sex matched healthy subjects were compared for resting values. Another nine healthy subjects were studied at rest and during exercise at a constant low load of 75W and at a high load defined as 80% of their individual maximal capacity. In patients with congestive heart failure mean plasma immunoreactive NPY at rest was 10.3 pmol l-1 and was not significantly different from the control group. No differences between patients with slight and severe CHF were found and there was no correlation between plasma immunoreactive NPY and left ventricular ejection fraction. Mean maximal exercise time was on average 6.3 min. Only three patients exercised more than 10 min. At maximal exercise mean plasma immunoreactive NPY was 10.6 pmol l-1 the same as at rest. Plasma noradrenaline was increased in CHF patients compared to healthy subjects, and rose further during exercise. In healthy subjects plasma immunoreactive NPY rose significantly on both workloads, but more on the high load (p < 0.05), when the rise was first significant after 10 min. Plasma immunoreactive NPY at rest and during exercise was not increased in CHF patients in optimal medical treatment. Consequently plasma immunoreactive NPY is not a useful marker of the severity of CHF in these patients. (ABSTRACT TRUNCATED AT 250 WORDS)
Infections in children with nephrotic syndrome.

OBJECTIVE To determine the different types of infections in nephrotic children and their association with the activity of disease. DESIGN A descriptive study. PLACE AND DURATION OF STUDY It was carried out at National Institute of Child Health (NICH), Karachi from August 1995-July 1996. PATIENTS AND METHODS All children with nephrotic syndrome who had various infections during the study period were evaluated for the activity of disease and type of infections. RESULTS Out of 62 children with nephrotic syndrome having infections, 45 (72.58%) were boys and 17 (27.42%) girls in a ratio of 2.5:1. Out of them 53 (85.45%) were known nephrotics and 36 (58%) of them were on steroid therapy. Nine were new cases and had not received steroids. A total of 74 episodes of infections were observed in 62 children. Acute respiratory infections (ARI) and skin infections were the most common (29.27% and 27.02% respectively) followed by diarrhoea (13.51%), UTI (12.5%) and peritonitis (10.81%). Two patients had pulmonary tuberculosis and 3 patients had more than one infection (cellulitis, peritonitis and pneumonia). All children with cellulitis and peritonitis were in active disease, whereas more than 80% of patients with ARI, diarrhoea and UTI were having either relapse or had recent onset of disease. CONCLUSION The study showed that ARI, cellulitis and diarrhoea were most common infections followed by UTI and peritonitis. Majority of the infections (>78%) were associated with active disease
Sources of contamination by polycyclic aromatic hydrocarbons in Spanish virgin olive oils

The presence of polycyclic aromatic hydrocarbons (PAHs) in virgin olive oils results from contamination on olive skins and the oil itself during processing. Determination of nine PAHs was carried out by isolation of the hydrocarbon fraction and subsequent clean-up by solid phase extraction, followed by RP-HPLC analysis using a programmable fluorescence detector. Contamination of olive skins depends directly on environmental pollution levels and inversely on fruit size. In the oil mill, PAHs levels were increased by contamination from combustion fumes during the extraction process. Other procedures, such as washing or talc addition during extraction, did not affect PAHs levels. High concentrations of PAHs were only found as a consequence of accidental exposure to contamination, such as direct contact of olives with diesel exhaust and oil extraction in a polluted environment.
Expression of BCL-2 proto-oncogene in adult acute lymphoblastic leukemia.

The products of the BCL-2 gene prolong survival of lymphohematopoietic cells by inhibition of programmed cell death. We studied bcl-2 protein expression in a series of 43 adult acute lymphoblastic leukemia (ALL) at diagnosis, using a specific monoclonal antibody and flow cytometry. All samples expressed bcl-2 with a mean percentage of positive cells of 77.9. The level of bcl-2 in positive cells expressed as mean equivalent of soluble fluorescence (MESF) was highly variable ranging from 5 x 10(3) to 552 x 10(3) (mean +/- s.d.: 96.5 +/- 109 x 10(3)). Neither the percentage of positive cells nor bcl-2 MESF levels were correlated with initial characteristics including blood counts, immunological phenotype, or cytogenetics. The survival of leukemic cells maintained in cytokine-free liquid culture was not correlated with bcl-2 expression. However, cells from ALL with higher white blood cell (WBC) counts, with t(9;22) translocation, or expressing myeloid surface antigens exhibited significantly longer survival in this culture system. The outcome after intensive chemotherapy did not differ according to bcl-2 expression. Factors associated with poor outcome included WBC counts, presence of t(9;22) translocation, presence of myeloid antigens and prolonged survival of cultured cells. These results indicate that high levels of bcl-2 are not associated with distinct clinical or biological characteristics in ALL.
The Ubiquitin E3 Ligase LOSS OF GDU2 Is Required for GLUTAMINE DUMPER1-Induced Amino Acid Secretion in Arabidopsis1[C][W][OA]

Amino acids serve as transport forms for organic nitrogen in the plant, and multiple transport steps are involved in cellular import and export. While the nature of the export mechanism is unknown, overexpression of GLUTAMINE DUMPER1 (GDU1) in Arabidopsis (Arabidopsis thaliana) led to increased amino acid export. To gain insight into GDU1’s role, we searched for ethyl-methanesulfonate suppressor mutants and performed yeast-two-hybrid screens. Both methods uncovered the same gene, LOSS OF GDU2 (LOG2), which encodes a RING-type E3 ubiquitin ligase. The interaction between LOG2 and GDU1 was confirmed by glutathione S-transferase pull-down, in vitro ubiquitination, and in planta coimmunoprecipitation experiments. Confocal microscopy and subcellular fractionation indicated that LOG2 and GDU1 both localized to membranes and were enriched at the plasma membrane. LOG2 expression overlapped with GDU1 in the xylem and phloem tissues of Arabidopsis. The GDU1 protein encoded by the previously characterized intragenic suppressor mutant log1-1, with an arginine in place of a conserved glycine, failed to interact in the multiple assays, suggesting that the Gdu1D phenotype requires the interaction of GDU1 with LOG2. This hypothesis was supported by suppression of the Gdu1D phenotype after reduction of LOG2 expression using either artificial microRNAs or a LOG2 T-DNA insertion. Altogether, in accordance with the emerging bulk of data showing membrane protein regulation via ubiquitination, these data suggest that the interaction of GDU1 and the ubiquitin ligase LOG2 plays a significant role in the regulation of amino acid export from plant cells.
An outbreak of avian malaria in captive yellowheads/mohua (Mohoua ochrocephala)

Abstract CASE HISTORY: Eight mohua, or yellowheads (Mohoua ochrocephala), were held in a large open aviary over the summer months of 2003–2004, following their capture for captivebreeding purposes. Two birds died of transportation trauma shortly after arrival, one became ill and died a month later, and another four died within a 2-week period in February 2004. The eighth bird also became ill at this time but survived for a year following treatment with chloroquine and doxycycline. CLINICAL AND PATHOLOGICAL FINDINGS: The affected birds were depressed, lethargic and dyspnoeic. Necropsy of three birds showed a slightly pale and swollen liver and spleen. Impression smears of the liver of one bird revealed schizonts resembling Plasmodium spp. within the cytoplasm of many hepatocytes, which was confirmed histopathologically. Similar protozoal organisms were seen within splenic histiocytes and pulmonary endothelial cells of 5/6 birds. Electron microscopy identified these as protozoal schizonts containing merozoites of similar size and structure to those of Plasmodium spp. DIAGNOSIS: The birds were infected with a protozoal haemoparasite resembling Plasmodium spp. ; asexual stages within hepatocytes and endothelial cells of the lung and spleen were typical of this organism. CONCLUSIONS AND CLINICAL RELEVANCE: The mohua captured from west Otago were highly susceptible to avian malaria as they came from an isolated population that was likely to be naïve and have had no previous contact with this organism. The birds were probably infected by bites from mosquitoes feeding off local populations of blackbirds subsequently found to be infected with Plasmodium spp.
Area per molecule and distribution of water in fully hydrated dilauroylphosphatidylethanolamine bilayers.

The area per lipid molecule for fully hydrated dilauroylphosphatidylethanolamine (DLPE) has been obtained in both the gel and liquid-crystalline states by combining wide-angle X-ray diffraction, electron density profiles, and previously published dilatometry results [Wilkinson, D. A. , & Nagle, J. F. (1981) Biochemistry 20, 187-192]. The molecular area increases from 41.0 +/- 0.2 to 49.1 +/- 1.2 A2 upon melting from the gel to liquid-crystalline phase. The thickness of the bilayer, as measured from the electron density profiles, decreases about 4 A upon melting, from 45.2 +/- 0.3 to 41.0 +/- 0.6 A. A somewhat unexpected result is that the fluid layer between fully hydrated bilayers is the same in both gel and liquid-crystalline phases and is only about 5 A thick. From these data, plus the volume of the anhydrous DLPE molecule, it is possible to determine the number of water molecules per lipid and their approximate distribution relative to the lipid molecule. Our analysis shows that there are about 7 and 9 waters per DLPE molecule in the gel and liquid-crystalline phases, respectively. About half of the water is located in the fluid space between adjacent bilayers, and the remaining waters are intercalated into the bilayer, presumably in the head group region. There are significantly fewer water molecules in the fluid spaces between DLPE bilayers than in the fluid spaces in gel- or liquid-crystalline-phase phosphatidylcholine bilayers. This small fluid space in PE bilayers could arise from interbilayer hydrogen bond formation through the water molecules or electrostatic interactions between the amine and phosphate groups on apposing bilayers.
Newer Insights into the Pathogenesis of Experimental Autoimmune Thyroiditis

Experimental autoimmune thyroiditis (EAT), produced in the mouse by immunization with murine thyroglobulin plus complete Freund's adjuvant, represents a valuable model for studying the pathogenesis of human chronic (Hashimoto's) thyroiditis. A major issue requiring clarification is the difference between benign autoimmunity, characterized solely by production of autoantibodies to thyroglobulin, and pathogenic autoimmunity where injury occurs to the thyroid cells. In this article, we describe the role of two key cytokines, IL12 and IFNγ, in modifying the pathogenic immune response. EAT, defined by cellular infiltration of the thyroid and the development of thyroglobulin-specific autoantibodies, is a dynamic process. Consequently, a cytokine may exert a different effect at different times during the disease process. For purposes of discussion, we propose that there are three stages in the development of EAT: priming; initiation; and progression. Administration of anti-IL12 during the priming stage and initiation dramatically decreases disease and lowers autoantibody levels. In contrast, injection of recombinant IL12 after disease was established significantly decreases the severity of disease and reduces autoantibody levels. Unlike IL-12, IFNγ was not essential for the priming of EAT. However, the severity of disease in the anti-IFNγ-treated initiation-and progression-treated animals was higher than in controls, implying a regulatory role for IFNγ. These findings emphasize that EAT involves a complex array of pathogenic mechanisms. The balance of cytokines produced during the early phase of the autoimmune reaction probably determines the progression from a harmless autoimmune response to autoimmune disease.
