Síntesis de Protoberberinas y Ciclopentil-isoquinoleínas Dopaminérgicas, y Síntesis de Indenopiridinas Melatoninérgicas
2015
Resumen – Discusión de los resultados. En la presente Tesis Doctoral se han desarrollado diversas rutas de síntesis para la obtención de alcaloides isoquinoleínicos, con diferentes esqueletos, y de hexahidroindenopiridinas. Además se han realizado sus correspondientes ensayos farmacológicos, sobre distintas dianas biológicas basándonos en los resultados obtenidos previamente con este tipo de alcaloides de síntesis y/o aislados de la naturaleza, y de moléculas estructuralmente similares. Se ha observado, a lo largo de muchos años, que las IQ son uno de los metabolitos secundarios activos (MSA) más abundantes y de mayor interés farmacológico de los aislados en especies de la familia de las An…
Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its …
2019
One of the main factors affecting historical art crafts material is the biodeterioration performed by bacteria and fungi, in archives, museums or private collections. Several microorganisms cause degradation to the natural organic material such as fibers, woods, and dyes as well as to stone objects. These alterations produce deterioration of physical, chemical, mechanical and esthetic properties. Consequently, in this publication, we report the high antibacterial and antifungal activities of wild thyme essential oil, oil that can be used as an alternative natural tool in the fight against microorganisms affecting historical art crafts.Essential oil of the Thymus capitatus growing wild in no…
Chemical composition and antimicrobial activity of the essential oil from aerial parts of Micromeria fruticulosa (Bertol.) Grande (Lamiaceae) growing…
2007
The essential oil of aerial parts of Micromeria fruticulosa (Lamiaceae) growing wild in Southern Italy was obtained by hydrodistillation and analysed by GC and GC–MS. Sixty-one compounds, representing 91.3% of the oil, were identified. The major components were γ-terpinene (14.5%), β-caryophyllene (12.6%), p-cymene (8.9%), α-pinene (8.2%) and β-bisabolene (7.2%). The essential oil showed action mainly against Gram-positive bacteria. Copyright © 2007 John Wiley & Sons, Ltd.
Patversmes pacientu sadarbība ar māsu aprūpes nodrošināšanā
2021
Bakalaura darba temats: Patversmes pacientu sadarbība ar māsu aprūpes nodrošināšanā Temata aktualitāte saistīta ar apstākli, ka Rīgā patversmēs tiek nodrošinātas sociālās gultas pacientiem, kas paredz ilgtermiņa un paliatīvu aprūpi. Latvijā nav veikti pētījumi par patversmes pacientu aprūpi kā holistisku procesu. Pētījuma mērķis: pētīt patversmes pacientu sadarbību ar māsu aprūpes nodrošināšanā. Pētījuma uzdevumi: 6. Pētīt literatūru par patversmes pacientu aprūpes nodrošinājumu un vajadzībām; 7. Analizēt M. Levinas māszinību teorijas pielietojumu patversmes pacientu aprūpē; 8. Pētīt sadarbības lomu māsu darbā ar patversmes pacientiem; 9. Veikt māsu un patversmes pacientu intervijas par sad…
Privātais testaments: institūta pilnveide un attīstība.
2021
Testamenta mērķis ir nodrošināt, ka cilvēka vēlmes tiks izpildītas no brīža, kad viņš pats aizies mūžībā. Šāds mērķis ir kā privātam, tā publiskam testamentam, tomēr ne vienmēr testators, uzrakstot privātu testamentu, sasniegs to pašu rezultātu, ja savu gribu būtu ietērpis publiski. Privāts testaments apveltīts ar tādām īpašībām kā vienkāršība un ērta izstrāde, jo testators to raksta un paraksta pašrocīgi. Tomēr privātam testamentam piemīt arī risks tikt viltotam, iznīcinātam, pazust vai, ka tā tekstu labos kāda trešā persona pretrunā testatora gribai. Bakalaura darba mērķis ir izpētīt, vai mūsdienu sabiedrībā privāts testaments nodrošina testatora pēdējās gribas konstatēšanu un izpildi. Au…
Treating chronic hepatitis C in daily practice with PEG-IFN alfa2B and ribavirin. An Italian multicentre study
2004
Retreatment with pegylated interferon plus ribavirin of chronic hepatitis C non-responders to interferon plus ribavirin: A meta-analysis.
2009
BACKGROUND/AIMS: Efficacy of retreatment with pegylated interferon (PEG-IFN) plus ribavirin of non-responders to standard or pegylated IFN plus ribavirin has been assessed in various studies, but sustained virologic response (SVR) rates are variable and factors influencing efficacy and tolerability still remain incompletely defined. We aimed to focus on SVR rates and to identify factors influencing them in this meta-analysis. METHODS: MEDLINE as well as a manual search were used. Studies were included if they were controlled or uncontrolled trials, if they had been published as full-length papers and if they included non-responders to standard or pegylated IFN and ribavirin therapy. Fourtee…
Antibacterial Efficiency of Surface-Immobilized Flavobacterium-Infecting Bacteriophage
2019
Control of bacterial diseases by bacteriophages (phages) is gaining more interest due to increasing antibiotic resistance. This has led to technologies to attach phages on surfaces to form a biomaterial that can functionally display phages that interact with bacteria, to carry out successful infection cycles. Such a material could be applied in many environments, where the target pathogens are expected. Although this approach has been applied successfully in a few studies already, the basis of the antibacterial effect by the immobilized phages is unclear, and the interpretation of the results depends on the study. Here, we studied the phage attachment density, their detachment rate and infe…
Biocompatibility and Antibacterial Properties of ZnO-Incorporated Anodic Oxide Coatings on TiZrNb Alloy
2020
In a present paper, we demonstrate novel approach to form ceramic coatings with incorporated ZnO nanoparticles (NPs) on low modulus TiZrNb alloy with enhanced biocompatibility and antibacterial parameters. Plasma Electrolytic Oxidation (PEO) was used to integrate ZnO nanoparticles (average size 12&ndash
