The phylogeny of Phylloporus (Boletaceae) has not been well studied, and the taxonomic relationships of this genus have varied considerably among authors. The following study presents phylogenetic relationships of Phylloporus based on two nuclear ribosomal DNA regions, ITS and LSU. The ITS dataset includes 39 collections and the LSU dataset contains 50(More)
Plant pathogenic fungi are a large and diverse assemblage of eukaryotes with substantial impacts on natural ecosystems and human endeavours. These taxa often have complex and poorly understood life cycles, lack observable, discriminatory morphological characters, and may not be amenable to in vitro culturing. As a result, species identification is(More)
AIM Bacterial reduction in oval-shaped root canals by a single-instrument technique was compared ex vivo with a conventional nickel-titanium rotary technique. Data obtained from two quantification methods, quantitative real-time polymerase chain reaction (qPCR) and culture, were also compared. METHODOLOGY Oval-shaped canals of extracted teeth contaminated(More)
Bisphosphonates (BPs) are characterized by a P-C-P backbone structure and two phosphonic acid groups bonded to the same carbon, and are established as osteoclast-mediated bone resorption inhibitors. The nature of the groups attached to the central carbon atom are responsible in determining the potency of bisphosphonates as anti-resorption drugs. However, it(More)
A taxonomic treatment of vinaceous and reddish species of Tubaria (Agaricales) is presented based on morphology and nucleotide sequences. Accessions from western North America, Europe, Central America, the Caribbean and Australia are compared. Phylogenetic analysis of the 25S rRNA gene and internal transcribed spacer (ITS) regions demonstrates that Tubaria(More)
AIM To evaluate in vivo the antibacterial effectiveness of the self-adjusting file (SAF) using molecular methods. METHODOLOGY Root canals from single-rooted teeth with apical periodontitis were instrumented using the SAF system under continuous irrigation with 2.5% NaOCl. DNA extracts from samples taken before and after instrumentation were subjected to(More)
Seventeen out of the 24 taxa of Phylloporus (Boletaceae) known from the Neotropics are presented here. Complete descriptions, illustrations and a key to the 17 species are provided. Phylloporus alborufus is newly described, and an unnamed species is also described from Costa Rican oak forests. Phylloporus colligatus was recently described from a Dicymbe(More)
Targeted radiopharmaceuticals have been mostly developed to visualize and/or treat oncologic diseases. In targeted radiotherapy radionuclide selection is a key issue, because the radionuclide should provide the appropriate radiation absorbed dose, matching the desirable biologic effect, but at the same time it should preclude irradiation of surrounding(More)
A previous publication reported the uptake into the lymphatics of pulmonary administered lipid nanoparticles (LN), after aerosolization and inhalation. In the present study LN clearance from the lungs and lymphatic uptake were further evaluated after endotracheal administration. Nanoparticles prepared with gliceryl behenate were radiolabelled by association(More)
Over more than two decades the existence of an adaptive response (AR) has been reported in several cell types and extensively studied with low doses of radiation. Besides radiation, some chemicals [alkylating compounds, mitomycin C (MMC), bleomycin, hydrogen peroxide and metals] may also induce an adaptive response. We have recently reported that the food(More)
