Gingivīta novērtēšana, izmantojot attālinātu fotopletismogrāfiju

2020

Pētījuma mērķis ir novērtēt smaganu perfūziju izmeklējamām personām izmantojot photopletizmogrāfijas metodi. Viens no pētījuma mērķiem bija reģistrēt kapsacīna izraisīto neiro-iekaisuma efektu. Metodoloģija Šķērsgriezuma pētījums, tika veikts iekļaujot nelielu izmeklējamo personu grupu , izmeklējamās personas pirms pētījuma veikšanas tika iepazīstinātas ar protokolu un rakstiski apstiprināja dalību pētījumā. Pētījuma gaitā smaganu perfūzijas tika reģistrēta miera apstākļos, un aplicējot uz smaganu virsmas kapsacīnu saturošu piparu ekstraktu, kas izraisīja pārejošu neirogēnu iekaisumu, ar tam raksturīgo hiperēmiju. Signāla reģistrācija tika veikta novietojot uz galvas izmeklējamai personai f…

Root hydraulic conductivity in three self-rooted and grafted table grape cultivars

2012

<p style="text-align: justify;"><strong>Aim</strong>: Root hydraulic conductivity is one of the main factors that control water flow in the soil-plant system and ultimately affect crop irrigation requirements. This work sets out to estimate root water conductivity for three self-rooted or grafted table grape cultivars.</p><p style="text-align: justify;"><strong>Methods and results</strong>: We evaluated root water conductivity of the cultivars ‘Black Magic’, ‘Matilde’ and ‘Victoria’ grafted onto 1103 Paulsen rootstock or self-rooted. Measurements were performed on two-year-old table grapes grown in pots filled with pumice. Root water conductivity wa…

Evidence of conservative treatment for overuse injuries analysis of systematic reviews

2011

Overuse injuries are common among top athletes and people who exercise regularly. Conservative, non-pharmacological methods are used widely to treat overuse injuries and there is a large body of literature, including multiple systematic reviews, evaluating different terms of treatment. This literature needs summarizing and critiquing. Objective of this study was to evaluate the effectiveness of different methods of conservative treatment on overuse injuries and to provide an analysis of systematic reviews. Published systematic reviews were identified by searching Medline, PEDro, Cochrane and Sportdiscus databases from the year 1996 to July 2010. Reference lists of identified studies were al…

Evolutionary advantage conferred by an eukaryote-to-eukaryote gene transfer event in wine yeasts

2015

Although an increasing number of horizontal gene transfers have been reported in eukaryotes, experimental evidence for their adaptive value is lacking. Here, we report the recent transfer of a 158-kb genomic region between Torulaspora microellipsoides and Saccharomyces cerevisiae wine yeasts or closely related strains. This genomic region has undergone several rearrangements in S. cerevisiae strains, including gene loss and gene conversion between two tandemly duplicated FOT genes encoding oligopeptide transporters. We show that FOT genes confer a strong competitive advantage during grape must fermentation by increasing the number and diversity of oligopeptides that yeast can utilize as a s…

Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.

2011

Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…

Endophytic Fungi in Asymptomatic Vitis vinifera L. and their Effects on Plasmopara viticola

2016

During a multi-year study on the life cycle of Plasmopara viticola to assess the typical epidemiology of downy mildew on grapevine (Vitis vinifera) in west Sicily (Italy), several leaves on which the downy mildew had collapsed were found and observed in a vineyard located in Marsala, in Trapani Province. An antagonistic fungus was isolated from these leaves and named A20; through its morphology, it was identified as a hyphomycete belonging to the genus Acremonium. The antagonism of A20 against the asexual and sexual spores of P. viticola, as well as endophytic nature of the genus Acremonium in V. vinifera were confirmed by further studies which have been carried out over the past decade. In…
