Effects of Purified Saccharomyces cerevisiae (1→3)-β-Glucan on Venous Ulcer Healing

Water-insoluble glucan was isolated from the baker’s yeast Saccharomyces cerevisiae. The yeast cells were treated with alkali and the residue then with acid. Chemical and NMR (1D and 2D) analyses showed that a linear (1→3)-β-glucan was purified that was not contaminated with other carbohydrates, proteins or phenolic compounds. The effects of the glucan on wound healing were assessed in human venous ulcers by histopathological analysis after 30 days of topical treatment. (1→3)-β-glucan enhanced ulcer healing and increased epithelial hyperplasia, as well as increased inflammatory cells, angiogenesis and fibroblast proliferation. In one patient who had an ulcer that would not heal for over 15 years, glucan treatment caused a 67.8% decrease in the area of the ulcer. This is the first study to investigate the effects of (1→3)-β-glucan on venous ulcer healing in humans; our findings suggest that this glucan is a potential natural biological response modifier in wound healing

Effects of the basic fibroblast growth factor and its anti-factor in the healing and collagen maturation of infected skin wound

PURPOSE: The infection is one of the main factors that affect the physiological evolution of the surgical wounds. The aim of this work is to evaluate the effects of fibroblast growth factor (FGFâ) and anti-FGFâ in the healing, synthesis and maturation of collagen when topically used on infected skin wounds of rats. METHODS: An experimental study was perfomed in 60 male Wistar rats. All animals were divided in two groups (A and B). Each group was divided in three subgroups A1, B1; A2, B2 and A3, B3. After anesthesia with pentobarbital, two open squared wounds (1cm2), 4cm distant to each other, were done in the dorsal skin of all the rats. In group A (n=30) the wounds were contaminated with multibacterial standard solution, and in group B(n=30) the wounds were maintained sterile. These wounds were named F1 (for inflammation analysis) and F2 (for collagen study). The open wounds of A1 and B1 rats were topically treated with saline solution, A2 and B2 were treated with FGFâ and subgroups A3 and B3 were treated with FGFâ and anti-FGFâ. The rats were observed until complete epitelization of F2 wounds for determination of healing time and the expression of types I and III collagen, using Picro Sirius Red staining. Inflammatory reaction in F1 wounds was studied using hematoxilineosin staining. The three variable was measured by the Image Pro-Plus Média Cybernetics software. The statistical analysis was performed by ANOVA and Tukey test, considering p<0.05 as significant. RESULTS: It was observed that infection retarded significantly (p<0.05) the time of wound scarring and the topical application of FCFb reverted the inhibition of healing caused by bacteria. The inflammatory reaction was greater in the subgroup B2 than in B1 and A3, and the difference was significant (p<0.05). It was observed greater expression of type I collagen in all the subgroups treated with FCFb, when compared with the untreated subgroups. Type III collagen was significantly decreased in wounds of B3 rats, comparing to the other subgroups. CONCLUSIONS: The FCFb accelerated the healing of open infected wounds and contributed with maturation of collagen, enhancing the type I collagen density. The anti-FCFb antibody was able to attenuate the production of both type I and III collagen

Spiritual reflections on the several chapters of Holy Scripture.

Spiritual guides: supporting adults who nurture the spirituality of children

This research considers the role of those who support voluntary youth leaders in their responsibility to nurture spiritual development in children and young people. It discusses particularly those who work in organisations with an ethos of supporting such spiritual development and at the same time of welcoming members of many faiths and encouraging their full participation in their various faith traditions. The specific context of the research is the work of the Guide Movement and, in particular, of Girlguiding in the United Kingdom. The research addresses the current challenges but also the enormous value of providing for young people a multi-faith space in which it is genuinely ‘OK to do God’. It discusses the issues which leaders are raising and some suggestions which trainers have made for addressing these.

Simvastatin improves the healing of infected skin wounds of rats

This study explores the potential of the simvastatin to ameliorate inflammation and infection in open infected skin wounds of rats. Methods: Fourteen Wistar rats weighing 285±12g were used. The study was done in a group whose open infected skin wounds were treated with topical application of sinvastatina microemulsion (SIM, n=7) and a second group with wounds treated with saline 0.9 % (SAL, n=7). A bacteriological exam of the wounds fluid for gram positive and gram negative bacteria, the tecidual expression of TNFá and IL-1â by imunohistochemical technique, and histological analysis by HE stain were performed. Results: The expression of TNFa could be clearly demonstrated in lower degree in skin wounds treated with simvastatin (668.6 ± 74.7 ìm2) than in saline (2120.0 ± 327.1 ìm2). In comparison, wound tissue from SIM group displayed leukocyte infiltration significantly lower than that observed in SAL group (p<0.05). Culture results of the samples taken from wound fluid on fourth post treatment day revealed wound infection in only one rat of group simvastatin (SIM), where Proteus mirabilis, Escherchia coli and Enterobacter sp were isolated. In the rats whose wounds were treated with saline (SAL), polymicrobial infection with more than 100,000 CFU/g was detected in all the wounds. Conclusion: In addition to its antiinflammatory properties, the protective effects of simvastatin in infected open skin wounds is able to reduce infection and probably has antibacterial action. The potential to treat these wounds with statins to ameliorate inflammation and infection is promising

Comparative study between the effects of hyaluronic acid and acid galactan purified from eggs of the mollusk Pomacea sp in wound healing

To compare the effect of hyaluronic acid (HA) and of AG on the healing of intestine wounds. Methods: The semi-purified extract of the eggs of the mollusc was obtained by fractionation with ammonium sulfate and purification for ion-exchange chromatography. The obtained galactans were eluted in water (neutral galactan) and in 0.1 and 0.2M NaCl (acidic galactans). The in vivo study was performed with 45 “Wistar” rats, separated in three groups (n=15). Solutions containing HA 1%, GA 1% or saline solution 0,9%, was placed topically on the sutures of wounds in the small intestine of the rats. After 05, 10 and 21 days the animals were sacrificed and biopsy of the healing tissue was done. Results: The hystologic grading was more significant for HA and AG groups when compared to the group C. AG stimulated the appearance of macrophages, giant cells and increase in the concentration of collagen in the area of the wound when compared to HA. Conclusion: The topical use of GA in intestinal wounds promoted the anticipation of events that are important in the wound healing

MAXIMIZING LANDSCAPE PERFORMANCE AT ADVENTIST HOSPITAL: HEALING THE PEOPLE, HEALING SLIGO CREEK

This paper answers the question of whether a design intervention on Washington Adventist Hospital’s Takoma Park campus can combine stormwater Best Management Practices with outdoor healing spaces, to improve the health of the local creek (Sligo Creek) while creating a restorative environment for the hospital community. To improve the health of Sligo Creek, a campus-wide stormwater analysis was undertaken, in addition to an intervention-site-specific stormwater analysis, and a literature review of stormwater best management practices. To create a restorative environment, a literature review of healing gardens was undertaken, in addition to a campus-wide site analysis, to uncover the most ideally suited site to create a restorative environment.

Effect of Melatonin and Analogues on Corneal Wound Healing: Involvement of Mt2 Melatonin Receptor

Purpose: We have investigated the effect of melatonin and its analogues on rabbit corneal epithelial wound healing. Methods: New Zealand rabbits were anaesthetised and wounds were made by placing Whatman paper discs soaked in n-heptanol on the cornea. Melatonin and analogues (all 10 nmol) were instilled. Wound diameter was measured every 2 hours by means of fluorescein application with a Topcon SL-8Z slit lamp. Melatonin antagonists (all 10 nmol) were applied 2 hours before the application of the n-heptanol-soaked disc and then every 6 hours together with melatonin. To confirm the presence of MT2 receptors in corneal epithelial cells immunohistochemistry, Western blot and RT-PCR assays in native tissue and in rabbit corneal epithelial cells were performed. The tear components were extracted then processed by HPLC to quantify melatonin in tears. Results: Migration assays revealed that melatonin and particularly the treatment with the MT2 agonist IIK7, accelerated the rate of healing (p < 0.001). The application of the non-selective melatonin receptor antagonist luzindole and the MT2 antagonist DH97 (but not prazosin), prevented the effect of melatonin on wound healing (both p < 0.001). Immunohistochemistry, Western blot and RT-PCR assays showed the presence of MT2 melatonin receptor in corneal epithelial cells. In addition, we have identified melatonin in tears and determined its daily variations. Conclusions: These data suggest that MT2 receptors are implicated in the effect of melatonin on corneal wound healing regulating migration rate. This suggests the potential use of melatonin and its analogues to enhance epithelial wound healing in ocular surface disease.

Sauvegarde et valorisation du patrimoine culturel immatériel du Sénègal: projet de création d'un écomusée des pratiques divinatoires et curatives

7 RESUME/ABSTRACT Au Sénégal, il existe des pratiques culturelles et cultuelles, séculaires que l’on retrouve au niveau de toutes les composantes ethnolinguistiques. Une donnée qui nous interpelle, chacun en ce qui nous concerne, et nous invite à repenser le devenir de nos spécificités et particularités culturelles face aux assauts répétés et multiformes de la modernité. La caractéristique qui entoure les rites et rituels est le plus souvent sujette à plusieurs formes d’interprétations fantaisistes et parfois dévalorisantes. Force est de reconnaître que le recours à la médecine moderne ne saurait pleinement répondre à ce besoin de tranquillité et de sérénité mystique qui habite chaque africain en général et chaque sénégalais en particulier. Il s’agit ici, pour l’africain et en ce qui nous concerne le sénégalais, de trouver une tranquillité psychologique et une assurance symbolique propres à créer les conditions d’une guérison physique et/ou morale. En ce sens que l’emprise du modernise ne peut aucunement influer totalement sur cette croyance ancestrale que bon nombre de sénégalais, et pas des moindres, ont en l’endroit de ces pratiques. Une prédisposition culturelle sous-tendue par des préoccupations cultuelles qui font l’objet d’une communion agissante entre les différents membres des communautés. Une prise de conscience qui se manifeste à travers des cérémonies ponctuellement organisées et présidées par des prêtres et prêtresses. Notre présente étude participe de la recherche d’un juste équilibre spirituel et temporel apte à offrir une possibilité de concilier les aspects traditionnels des spécificités culturelles de nos composantes ethnolinguistiques avec ce qui constitue les contraintes et exigences de la modernité. Il reste certes évident que cette opposition a généré une sorte de fracture culturelle en véhiculant une autre manière de voir, mais surtout de percevoir nos traditions et coutumes. Cependant à l’heure d’un redimensionnement et d’une adaptation contextuelle de ce qui constitue nos valeurs identitaires, il nous revient de procéder à une démarche de sensibilisation et d’explication pour conférer plus de lisibilité à nos expressions culturelles. La mise en place d’un écomusée des pratiques divinatoires et curatives, est un moyen moderne et pratique de sauvegarde et de valorisation des savoirs et connaissances thérapeutiques endogènes. Outre la création d’emplois et de revenus, cette infrastructure sera une vitrine du patrimoine local qui favorisera le développement d’un tourisme culturel source de devises et vecteur de développement local; ABSTRACT: In Senegal, there are cultural and religious practices, ancient that we find in all the ethno-linguistic components. A given that challenges us, each in our case, and invites us to rethink the future of our cultural specificities and characteristics and multifaceted face of repeated assaults of modernity. The characteristic surrounding the rites and rituals is usually subject to various forms of demeaning and sometimes fanciful interpretations. We must recognize that the use of modern medicine can not fully meet this need of tranquility and mystical serenity that inhabits every African in general and Senegal in particular each. This is, for Africa and for us Senegalese, find a psychological tranquility and symbolic own insurance to create conditions for physical healing and / or legal. In that the grip of modernizing can in no way affect totally on this ancient belief that many Senegalese, not least, have the place of such practices. A cultural predisposition underpinned by cultic concerns that are the subject of an active communion between the community members. An awareness that manifests itself through occasionally organized ceremonies presided over by priests and priestesses. Our present study involved the search for a fair balance spiritual and temporal able to offer an opportunity to reconcile the traditional aspects of the cultural specificities of our ethno-linguistic components with which constitutes the constraints and demands of modernity. While it remains clear that this opposition has generated a kind of cultural divide by conveying a different way of seeing, but above all to collect our traditions and customs. However at the time resizing and contextual adaptation of what constitutes our identity values, it is our responsibility to conduct an outreach approach and explanation to give greater clarity to our cultural expressions. The establishment of a museum of divination and healing practices, is a modern and convenient way to backup and recovery of therapeutic knowledge and endogenous knowledge. In addition to creating jobs and income, this infrastructure will be a showcase of local heritage that promote the development of cultural tourism source of foreign exchange and local development vector.

Intrusion Detection Systems in SDN-based Self-Healing PMU Networks

Nowadays, Power grids are critical infrastructures on which everything else relies, and their correct behavior is of the highest priority. New smart devices are being deployed to be able to manage and control power grids more efficiently and avoid instability. However, the deployment of such smart devices like Phasor Measurement Units (PMU) and Phasor Data Concentrators (PDC), open new opportunities for cyber attackers to exploit network vulnerabilities. If a PDC is compromised, all data coming from PMUs to that PDC is lost, reducing network observability. Our approach to solve this problem is to develop an Intrusion detection System (IDS) in a Software-defined network (SDN). allowing the IDS system to detect compromised devices and use that information as an input for a self-healing SDN controller, which redirects the data of the PMUs to a new, uncompromised PDC, maintaining the maximum possible network observability at every moment. During this research, we have successfully implemented Self-healing in an example network with an SDN controller based on Ryu controller. We have also assessed intrinsic vulnerabilities of Wide Area Management Systems (WAMS) and SCADA networks, and developed some rules for the Intrusion Detection system which specifically protect vulnerabilities of these networks. The integration of the IDS and the SDN controller was also successful. \\To achieve this goal, the first steps will be to implement an existing Self-healing SDN controller and assess intrinsic vulnerabilities of Wide Area Measurement Systems (WAMS) and SCADA networks. After that, we will integrate the Ryu controller with Snort, and create the Snort rules that are specific for SCADA or WAMS systems and protocols.
