Über den Allantoinstoffwechsel des Laubmooskallus und seine Beeinflussung durch Licht

1972

Summary 1. The amount of allantoin and allantoate was determined in moss callus grown under various light conditions. It can reach 26,5 % of the plant nitrogen content. The accumulation is influenced by light intensity and colour. 2. Red-light (660 nm) causes a greater allantoin level in the cells than blue light and white light illumination. Red-light favours the formation of young setae from the moss callus. We could detect a relation between the intensity of seta-development and the amount of allantoin. The accumulation is increasing with the growth of the setae. 3. Blue-light (440 nm) enhances the chlorophyll synthesis and promotes chloroplast develop ment. This effect is correlated wit…

Blood flow shapes intravascular pillar geometry in the chick chorioallantoic membrane.

2010

The relative contribution of blood flow to vessel structure remains a fundamental question in biology. To define the influence of intravascular flow fields, we studied tissue islands--here defined as intravascular pillars--in the chick chorioallantoic membrane. Pillars comprised 0.02 to 0.5% of the vascular system in 2-dimensional projection and were predominantly observed at vessel bifurcations. The bifurcation angle was generally inversely related to the length of the pillar (R = -0.47, P .05). 3-dimensional computational flow simulations indicated that the intravascular pillars were located in regions of low shear stress. Both wide-angle and acute-angle models mapped the pillars to regio…

Non-Steroidal Anti-Inflammatory Agents, Part 20[1] Method for Testing Non-Steroidal Anti-Inflammatories: The Modified Hen's Egg Chorioallantoic Membr…

1996

The delay of onset of irritation phenomena at the chorioallantoic membrane of incubated hen's eggs, a parameter for anti-inflammatory activity, was determined for the pharmaceutical substances diclofenac, flufenamic acid, ibuprofen, indomethacin, ketoprofen, piroxicam, phenylbutazone, salicylic acid, and sodium salicylate. Alongside questions relating to the dose-effect ratio, metabolisation, recovery, and diffusion of the substances to their site of action were investigated. The reproducibility of the procedure and its selectivity with regard to substances with a different mechanism of action is proven. The method allows classification of the substances according to their anti-inflammatory…

Efficacy of a topical gel containing chitosan, chlorhexidine, allantoin and dexpanthenol for pain and inflammation control after third molar surgery …

2020

BACKGROUND: The aim of this study was to evaluate and compare the postoperative effect of a topic gel containing chlorhexidine, chitosan, allantoine and dexpanthenol versus a placebo for pain and inflammation control after third molar surgery. MATERIAL AND METHODS: A gel combining 0.2% chlorhexdine, 0.5% chitosan, 5% dexpanthenol, 0.15% allantoin and 0.01% sodium saccharin was selected for this split mouth randomized controlled and double-blind trial including 36 patients with bilaterally and symmetrically impacted lower third molars. The teeth (n=72) were randomly divided into two groups before surgical removal: control group (CG; in which a placebo was given) and experimental group (EG). …

The effects of a topical gel containing chitosan, 0,2% chlorhexidine, allantoin and despanthenol on the wound healing process subsequent to impacted …

2016

Background Despite efforts to prevent postoperative discomfort, there are still many immediate side effects associated with the surgical extraction of impacted lower third molars. Cicatrization is a physiological process through which the loss of integrity of oral mucosa is recovered and damaged tissues are repaired. Bexident Post (ISDIN, Spain) is a topical gel that contains chitosan, 0.2% chlorhexidine, allantoin and dexpanthenol. While this gel has many clinical indications, there are no published clinical trials evaluating its use in impacted mandibular third molar surgery. This study aims to clinically evaluate the efficacy of a gel containing chitosan, 0.2% chlorhexidine, allantoin an…

Photocleavable core cross-linked polymeric micelles of polypept(o)ides and ruthenium(II) complexes

2021

Core cross-linking of polymeric micelles has been demonstrated to contribute to enhanced stability that can improve the therapeutic efficacy. Photochemistry has the potential to provide spatial resolution and on-demand drug release. In this study, light-sensitive polypyridyl-ruthenium(II) complexes were combined with polypept(o)ides for photocleavable core cross-linked polymeric micelles. Block copolymers of polysarcosine-block-poly(glutamic acid) were synthesized by ring-opening N-carboxyanhydride polymerization and modified with aromatic nitrile-groups on the glutamic acid side chain. The modified copolymers self-assembled into micelles and were cross-linked by cis-diaquabis(2,2'-bipyridi…

Maria Magdalena dins l'univers barroc: entre el plor i l'èxtasi

2008

Una de las imágenes más características de Maria Magdalena, en los albores del Barroco, es la que la representa en la soledad de su vida retirada del mundo, con los cabellos al viento, jugando a cubrir sensual-mente su cuerpo desnudo y en el instante en que el acto de penitencia, asociado frecuentemente a su llanto, se convierte en espasmo extático. El pequeño trabajo que proponemos pretende tratar la evolución hacia esta representación del personaje, su contenido dramático generador de catarsis y construir a la vez un itinerario a través de sus identidades y de la leyenda que la ha dotado de peripecia y caracteres.

Tears evoke the intention to offer social support: A systematic investigation of the interpersonal effects of emotional crying across 41 countries

2021

Tearful crying is a ubiquitous and likely uniquely human phenomenon. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by evoking social support intentions. Initial experimental studies supported this proposition across several methodologies, but these were conducted almost exclusively on participants from North America and Europe, resulting in limited generalizability. This project examined the tears-social support intentions effect and possible mediating and moderating variables in a fully pre-registered study across 7007 participants (24,886 ratings) and 41 countries spanning all populated continents. Participants were prese…

Ferrocenyl-Coupled N-Heterocyclic Carbene Complexes of Gold(I)

2016

Four gold(I) carbene complexes featuring 4-ferro-cenyl-substituted imidazol-2-ylidene ligands were investigated for antiproliferative and antivascular properties. They were active against a panel of seven cancer cell lines, including multidrug-resistant ones, with low micromolar or nanomolar IC50 (72 h) values, according to their lipophilicity and cellular uptake. The delocalized lipophilic cationic complexes 8 and 10 acted by increasing the reactive oxygen species in two ways: through a genuine ferrocene effect and by inhibiting the thioredoxin reductase. Both complexes gave rise to a reorganization of the F-actin cytoskeleton in endothelial and melanoma cells, associated with a G1 phase c…
