Topical Anti-Inflammatory Lignans from Haplophyllum hispanicum Haplophyllum hispanicum
1996
The present paper reports the results of the methanol extract of Haplophyllum hispanicum Spach on single or repeated local 12-O-tetradecanoylphorbol acetate (TPA) administration and in the oxazolone-induced contact-delayed hypersensitivity mouse ear edemas. Two topical anti-inflammatory aryl naphthalide lignans were isolated from the active fractions of the methanol extract. They were identified by spectroscopic methods, including 13C NMR and heteronuclear multiple bond correlation (HMBC), as diphyllin acetyl apioside and tuberculatin. The former was the most active on acute TPA edema with a ID50 of 0.27 μmol/ear
Ionic Liquids on Demand in Continuous Flow
2009
We report on the development of an alternative protocol for the facile, solvent-free synthesis of various novel imidazolium-based ionic liquids (ILs) that affords highly pure products without the necessity of subsequent purification steps. The continuous approach is based on the combination of HPLC pumps with a micromixer and a capillary residence tube. Our system provides a high degree of control over the alkylation reactions due to a high surface-to-volume ratio and superior heat and mass transport. Within the scope of our studies, we focused on ionic liquids containing differently substituted phenyl rings and characterized these compounds with respect to further use for direct applicatio…
Comparison of the Effects of Indole-3-Acetic Acid and Kinetin on the Photosynthetic Apparatus and on the Cell Metabolism
1984
External and internal factors can exert a regulatory influence on growth and differentiation within a reaction norm determined by the genetic material. As to the internal factors, the phytohormones intervene in the most development processes in a regulatory manner. In a number of publications it was pointed out that there is a far-reaching accordance between the effects caused by I.4A and the effects induced by red light and low light conditions (Zerbe, Wild, 1980 a; Holzapfel et al., 1982 a). Plants of Sinapis alba grown under low light conditions but additionally treated with kinetin show changes in their metabolism that are characteristic of plants grown at higher light intensities (Zerb…
The chemical composition of essential oil from Seseli bocconei (Apiaceae) aerial parts growing in Sicily (Italy)
2022
Seseli is a large genus of aromatic and economically important herbs of the Apiaceae family that includes eighty-seven taxa, mainly distributed in Europe and Asia. Several species of this genus are extensively used in various popular medicines and based on their traditional uses, much research concerning biological activities have been carried out. In the present study, the chemical composition of the essential oil from aerial parts of Seseli bocconei Guss., a rare plant endemic of Sicily, was analysed by GC-MS. No one report has been previously published on the essential oil of this species. The result showed the presence of large quantity of monoterpene and sesquiterpene hydrocarbons wher…
The chemical composition of essential oil from Seseli tortuosum subsp. tortuosum and S. tortuosum subsp. maritimum (Apiaceae) aerial parts growing in…
2022
Seseli L. genus, belonging to the Apiaceae family, includes more than eighty taxa, mainly growing in Europe and Asia. Due to the several biological properties, species of this genus have been largely investigated, showing to be a rich source of coumarins, as well as, of essential oils with anti-inflammatory, antiviral, antifungal, cytotoxic, etc. properties. In the present study, the chemical composition of the essential oils from aerial parts of Sicilian accessions of Seseli tortuosum subsp. tortuosum and S. tortuosum subsp. maritimum were analysed by GC-MS. No one report has been previously published on the subsp. maritimum. The results showed the presence, in both oils, of large quantity…
Flogosi post-trapianto di cornea
2013
Il Trapianto di Cornea, o Cheratoplastica, che prevede la sostituzione sub-totale della cornea mediante un innesto circolare di tessuto omologo (lembo), rappresenta la procedura d’elezione per il trattamento di diverse patologie corneali congenite o acquisite. Se ne discutono tutti i determinanti e le prospettive.
Pathways between Social Capital and Oral Health from Childhood to Adolescence
2022
Author's accepted manuscript This study aimed to evaluate the theoretical pathways by which social capital can influence dental caries and oral health–related quality of life (OHRQoL) of children over time. This 10-y prospective cohort started in 2010 with a sample of 639 preschoolers aged 1 to 5 y from the southern Brazil. Community and individual social capital were assessed at baseline through the presence of formal institutions in the neighborhood and social networks, respectively. In the 10-y follow-up, the individual social capital was evaluated by social trust and social networks. Dental caries was measured by the International Caries Detection and Assessment System (ICDAS), and the …
Distraction as a technique to control pain in pediatric patients during venipuncture. A narrative review of literature
2015
Introduzione: La distrazione è un intervento non farmacologico in grado di ridurre l’intensità del dolore procedurale nei bambini. Tra le procedure maggiormente diffuse, la venipuntura è una di quelle maggiormente applicate in area pediatrica, per scopi diagnostici e terapeutici. L’analgesia durante la venipuntura può essere efficacemente raggiunta con tecniche di distrazione. Obiettivo: descrivere l’efficacia delle tecniche di distrazione attiva e passiva per la riduzione del dolore, nei bambini sottoposti a venipuntura. Metodi: è stata realizzata una revisione della letteratura consultando i database CINHAL, PubMed, ILISI e Cochrane. Sono stati inclusi tutti studi primari e secondari pubb…
The influence of short term, intensive hippotherapy on gait in children with cerebral palsy
2010
The purpose of this study was to investigate the effects of short term hippotherapy on functional gait changes in children with cerebral palsy (CP). Participants were two boys (ages 12 and 13) with spastic diplegia and a girl (14 yrs) with athetoid CP. Single-subject (ABA) design was used to determine quantitative changes in functional gait parameters (velocity, stride length, and cadence) following three weeks of hippotherapy. The two boys demonstrated improvement in stride length and gait velocity without sustained improvement in cadence. There was increase in stride length and cadence, but most noticeable improvements in velocity for the girl. The results indicated that it is possible th…
