L'innovazione nelle tecnologie biomediche tra rischio, incertezza, precauzione e gestione
No full textMrakia fibulata sp. nov., a psychrotolerant yeast from temperate and cold habitats
No full textTree fluxes are sugar-rich, sometimes
ephemeral, substrates occurring on sites where tree
sap (xylem or phloem) is leaking through damages of
tree bark. Tree sap infested with microorganisms has
been the source of isolation of many species, including
the biotechnologically relevant carotenoid yeast Phaffia
rhodozyma. Tree fluxes recently sampled in
Germany yielded 19 species, including several psychrophilic
yeasts of the genus Mrakia. Four strains
from tree fluxes represented a potential novel Mrakia
species previously known from two isolates from
superficial glacial melting water of Calderone Glacier
(Italy). The Italian isolates, originally identified as
Mrakia aquatica, and two strains from Germany did
not show any sexual structures. But another culture
collected in Germany produced clamped hyphae with
teliospores. A detailed examination of the five isolates
(three from Germany and two from Italy) proved them
to be a novel yeast species, which is described in this
manuscript as Mrakia fibulata sp. nov. (MB 830398),
holotype DSM 103931 and isotype DBVPG 8059. In
contrast to other sexually reproducing Mrakia species,
M. fibulata produces true hyphae with clamp connections.
Also, this is the first psychrotolerant Mrakia
species which grows above 20 C. Spring tree fluxes
are widespread and can be recognized and sampled by
amateurs in a Citizen Science project. This substrate is
a prominent source of yeasts, and may harbor
unknown species, as demonstrated in the present
work. The description of Mrakia fibulata is dedicated
to our volunteer helpers and amateurs, like Anna
Yurkova (9-years-old daughter of Andrey Yurkov),
who collected the sample which yielded the type strain
of this species
Catalyst development for steam reforming of methane and model biogas at low temperature
No full textLow temperature steam reforming (400-550°C) for the production of hydrogen offers significant advantages compared to the conventional process. The milder operating conditions lead to lower operation costs and cost of construction materials. Additionally, no CO shift reactor is required due to favorable temperature for the WGS reaction. In this work, we report the catalytic performance of Ni and Rh catalysts supported on La2O3-ZrO2 and La2O3-CeO2-ZrO2 for their application in a multifuel membrane reformer operating at low temperature. The performance of the catalysts is assessed in different operating conditions in methane steam reforming (GHSV, temperature, H2O/CH4ratio) as well as in reforming of model biogas. Stability tests were conducted up to 90h on stream (1bar and 7bar) and the tendency toward carbon formation was investigated. All catalysts were active in the reforming reactions at 400-550°C and the catalysts supported on La2O3-CeO2-ZrO2 showed superiority in activity and stability probably due to the presence of ceria in the support which contributes to the reforming rate and the resistance to carbonaceous deposits. Ni(10)CeZrLa exhibited remarkably stable performance with minimum amount of carbon formed after 90h (ca. 0.05wt%). TPO and TPH analysis of the carbonaceous deposits showed that the dominating type of carbon is highly reactive and can be easily removed by oxidation or hydrogenation at 500°C. This fact makes the catalyst even more promising for the proposed low temperature process, since the catalyst can be hydrogenated by using part of the H2 production stream without further heating of the reactor. © 2015 Elsevier B.V.
Outcomes of support groups for carriers of BRCA 1/2 pathogenic variants and their relatives: a systematic review
No full textPeople tested positive for BRCA1/2 face an increased risk of cancer; to help them cope with the genetic information received, support to BRCA1/2 families should be continued after testing. Nonetheless how such support should be provided has not been established yet. As a potentially valuable option is represented by support groups, the aim of this systematic review was to assess studies exploring the outcomes of support groups for BRCA1/2 carriers. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42021238416). Peer-reviewed papers published between January 1995 and February 2021 were searched for, using four databases. Among 1586 records identified, 34 papers were reviewed in full-text and eleven were included in the qualitative synthesis of the results. Three themes emerged as major focuses of support groups: risk management decisions, family dynamics and risk communication, and psychosocial functioning. Our findings show that support groups proved helpful in supporting women’s decision-making on risk-reducing options. Moreover, during those interventions, BRCA1/2 carriers had the opportunity to share thoughts and feelings, and felt that mutual support through interacting with other mutation carriers help them release the emotional pressure. However, no significant impact was reported in improving family communication. Overall, a high level of satisfaction and perceived helpfulness was reported for support group. The findings suggest that support groups represent a valuable tool for improving BRCA1/2 families care
Rare and undersampled dimorphic basidiomycetes
No full textThe diversity of yeasts has grown rapidly as the discovery of new species has benefited from intensified sampling and largely improved identification techniques. An environmental study typically reports the isolation of yeast species, some of which are new to science. Rare species represented by a few isolates often do not result in a taxonomic description. Nucleic acid sequences from these undescribed yeasts remain in public sequence databases, often without a proper taxonomic placement. This study presents a constrained phylogenetic analysis for many rare yeasts from unpublished but publicly available DNA sequences and from studies previously conducted by the authors of this work. We demonstrate that single isolates are an important source of taxonomic findings such as including new genera and species. Independent surveys performed during the last 20 years on a large geographic scale yielded a number of single strains, which were proved to be conspecific in the phylogenetic analyses presented here. The following new species were resolved and described: Vustinia terrea Kachalkin, Turchetti & Yurkov gen. nov. et sp. nov.; Udeniomyces caspiensis Kachalkin sp. nov.; Udeniomyces orazovii Kachalkin sp. nov.; Tausonia rosea Kachalkin sp. nov.; Itersonilia diksonensis Kachalkin sp. nov.; Krasilnikovozyma fibulata Glushakova & Kachalkin, Kwoniella fici Turchetti sp. nov.; Heterocephalacria fruticeti f.a. Carvalho, Roehl, Yurkov & Sampaio sp. nov.; Heterocephalacria gelida f.a. Turchetti & Kachalkin sp. nov.; Heterocephalacria hypogea f.a. Carvalho, Roehl, Yurkov & Sampaio sp. nov.; Heterocephalacria lusitanica f.a. Inacio, Carvalho, Roehl, Yurkov & Sampaio sp. nov.; Piskurozyma arborea Yurkov, Kachalkin, Mašínová & Baldrian sp. nov.; Piskurozyma silvicultrix Turchetti, Mašínová, Baldrian & Yurkov sp. nov.; Piskurozyma stramentorum Yurkov, Mašínová & Baldrian sp. nov.; Naganishia nivalis Turchetti sp. nov.; and Yurkovia nerthusi Yurkov & Begerow, sp. nov. In addition, two new combinations were proposed Krasilnikovozyma curviuscula (Babeva, Lisichkina, Reshetova & Danilevich) Yurkov, Kachalkin & Sampaio comb. nov. and Hannaella taiwanensis (F.L. Lee & C.H. Huang) Yurkov comb. nov. The order Cyphobasidiales T. Spribille & H. Mayrhofer is rejected in favor of the older name Erythrobasidiales R. Bauer, Begerow, J.P. Sampaio, M. Weiss & Oberwinkler. Other potential novel species identified in this paper await future description. Phylogenetic placement of yet unpublished sequences is believed to facilitate species descriptions and improve classification of yeasts from environmental sequence libraries
Dynamics and thermodynamics of a gas automata
No full textWe consider a system of point charges interacting within a cone of vision and confined by an external potential, as a simple model of individuals provided with vision. The non Newtonian nature of the interaction introduces dissipative effects which are balanced by a memory mechanism. The two-body system is amenable to quadrature, whereas the body system exhibits crystal-like and disordered states with a non-trivial phase diagram if the interaction range and memory persistence are chosen as control parameters
