Mediterranean spotted fever: clinical and laboratory characteristics of 415 Sicilian children

2006

Abstract Background Mediterranean spotted fever (MSF) is an acute febrile, zoonotic disease caused by Rickettsia conorii and transmitted to humans by the brown dogtick Rhipicephalus sanguineus. Nearly four hundred cases are reported every year (mainly from June to September) on the Italian island of Sicily. The aim of the study was to analyze the clinical and laboratory characteristics of patients with MSF and the efficacy of the drugs administered. Methods Our study was carried out on 415 children with MSF, during the period January 1997 – December 2004, at the "G. Di Cristina" Children's hospital in Palermo, Sicily, Italy. On admission patients' clinical history, physical and laboratory e…

Mycelium Growth and Biological Efficiency of Ganoderma lucidum on Substrate Supplemented with Different Organic Additives

2015

Ganoderma lucidum (W. Curt.: Fr) P. Karst. is a mushroom exhibiting various medicinal properties, popular particularly in Asia. It is grown on a substrate based on hardwood sawdust. Other organic materials, usually agricultural or industrial waste supplemented with various additives, are also used in the cultivation of this mushroom. Numerous studies have shown that the composition of the substrate has a significant effect on mycelium growth and biological efficiency of Reishi mushroom. The presented analysis determined the effect of different organic substances on mycelium growth and biological efficiency of several G. lucidum isolates (Gan 18, Gan Li 27/3, Gan 7, Gan 112) obtained from mu…

Mycoforestry in Sicily: a proposal to enhance the multifunctionality of forests

2017

Mycoforestry is forestry that aims to build on traditional rules to encourage forest ecosystem resilience while creating optimal conditions for fungal communities. Main goals of mycoforestry are: preservation of native forests, recovery and recycling of woodland debris, enhancement of replanted trees, strengthening sustainability of ecosystems, economic diversity. There is a large variety of fungi living in forests, each of which has a specific and complementary relationship to the diversity of native species, the ages of trees, the presence of dead trees or rich forest litter, etc. Fungi are the main responsible of wood decomposition and thus carbon and nutrient cycling, and they also form…

Ferdinanda Erdmaņa Štolla kāpu tintenes akvareļi

2020

1925. gada jūnijā Baltijas dabaspētnieks Ferdinads Erdmanis Štolls (1874 – 1966) Garciema smilšu kāpās atklāja jaunu sēņu sugu, kam tika dots nosaukums Coprinus dunarum F. E. Stoll, latviski – kāpu tintene. Zinātnieks sēnes fiksēja un detalizēti aprakstīja. Atraduma fotouzņēmumi un akvareļi ir iekļauti viņa vairāk kā 1000 vienību lielajā F. E. Štolla sēņu attēlu kolekcijā, kuru pamatā veido F. E. Štolla zīmētie akvareļi, kas glabājas Latvijas Universitātes muzeja Botānikas un mikoloģijas kolekcijās.

The occurrence of mycorrhizal fungi in Betula aetnensis Raf. roots: from ecological role to conservation strategies

2017

Betula aetnensis Raf. is an endemic tree species of particular conservation value. It only thrives in the north-eastern slopes of Mount Etna (Sicily), from 1200 to 2100 m a.s.l. This pioneer plant is able to begin primary succession on nutrient-poor and water-limited soils (C = 0.17%; N = 0.05 ‰; P2O5 = 4.1 ppm), where beneficial mycorrhizal fungi (MF) may play a crucial role. In order to investigate MF role in B. aetnensis, plant roots from natural sites and nursery grown specimens were analyzed for both ectomycorrhizal and endomycorrhizal structures. Typical structures of both symbiosis were detected by root staining and morphological observations. Ectomycorrhizae (EM) were more abundant …

Phylogenetic diversity and affiliation of tropical African ectomycorrhizal fungi

2022

Ectomycorrhizal fungi form a mutualistic symbiosis with plant roots, and are key for nutrient cycling in many ecosystems. Here we study the ectomycorrhizal fungal communities in the Oueme Superieur reserve forest in Benin (West Africa). We use phylogenetic methods to test if the species from the study site are closer to other tropical African species than to species from other regions. The Oueme Superieur community was represented by nine Operational Taxonomic Units in Amanitaceae, one in Boletaceae, one in Cantharellaceae, one in Cortinariaceae, two in Inocybaceae, fourteen in Russulaceae and three in Sclerodermataceae. Of these thirty-one Operational Taxonomic Units, twenty had no record …

Purīnu šķērsbarošanās mākslīgās maizes rauga Saccharomyces cerevisiae sabiedrībās

2020

Maizes raugs Saccharomyces cerevisiae ir vienkāršs eikariotisku šūnu modeļorganisms ar ko iespējams pētīt procesus gan molekulārā, gan populāciju līmenī. Izmantojot maizes raugu ir iespējams modelēt dažādu eikariotisku organismu populāciju konkurenci ierobežotu resursu apstākļos. Tas savukārt attiecas uz praktiskiem biotehnoloģiskiem pielietojumiem pārtikas rūpniecībā, medicīnā un ekoloģiskiem pētījumiem. Mikroorganismu kokultivācijā notiek divu vai vairāku organismu kultivēšana izolēta vidē. Tas ir metode bioloģiskas sabiedrības un organismu konkurences pētīšanai laboratorijas apstākļos. Izmantojot maizes raugu Saccharomyces cerevisiae kā modeļorganismu var pētīt atsevišķu organismu mutual…

Integración de la genómica en la modelización de los tumores neuroblásticos = Integration of genomics in neuroblastic tumors modeling

2015

*Introducción: El neuroblastoma es un tumor maligno embrionario del sistema nervioso simpático con una gran heterogeneidad en la presentación clínica, morfológica y genética y en otras características biológicas. La estratificación de grupos de riesgo pretratamiento se basa en los siguientes factores: edad, estadio, histopatológica del tumor, estado del oncogén MYCN, integridad del brazo cromosómico 11q y ploidía. Por otra parte, los cambios numéricos y estructurales detectados en el perfil genético se han incluido recientemente en la estratificación terapéutica de los pacientes con bajo riesgo a recaer o morir. El amplio espectro clínico de la enfermedad va desde pacientes con neuroblastom…
