The endangered freshwater pearl mussel Margaritifera margaritifera shows adaptation to a local salmonid host in Finland
2022
1. The freshwater pearl mussel Margaritifera margaritifera (FPM) is an endangered unionid which has a glochidium larva that attaches to the gills of Atlantic salmon Salmo salar or brown trout S. trutta, although some FPM populations have been shown to exclusively attach to only one of these species. The origin of host fish populations may be crucial for conservation actions for this mussel species, but the relative suitability of local (sympatric) and non- local (allopatric) salmonid populations as the hosts for FPM has been studied only rarely. We hypothesised that FPM glochidia would show adaptation to local salmonid strains and, there-fore, that they would be more successful (abundant, l…
Peritoneaalidialyysipotilaiden elämänlaatu sekä ikääntymisen yhteys hoitojen sujuvuuteen, potilaana selviytymiseen ja elämänlaatuun
2015
Suomalaisen väestön yleisimpiä pitkäaikaissairauksia ovat perinteisesti olleet erilaiset sydän- ja verisuonisairaudet. Diabeteksen esiintyvyys on voimakkaassa kasvussa, jonka vuoksi siitä on tullut myös yksi maamme yleisimmistä pitkäaikaissairauksista. Yhdessä nämä sairaudet ovat edesauttaneet erilaisten munuaissairauksien yleistymistä. Myös ikääntymisen on nähty olevan yhteydessä munuaissairauksien lisääntymiseen. Tässä pro gradu- tutkielmassa mielenkiinto kohdistettiin kroonista munuaisten vajaatoimintaa sairastaviin yksilöihin. Tutkimuksessa tarkoituksena oli tutkia peritoneaalidialyysipotilaiden elämänlaatua sekä ikääntymisen yhteyttä hoitojen sujuvuuteen, potilaana selviytymiseen ja el…

Focusing on Ciona intestinalis (Tunicata) innate immune system. Evolutionary implications
2009
Phylogenetic analyses based on molecular data provide compelling evidence that ascidians are of critical importance for studying chordate immune system evolution. The Ciona intestinalis draft genome sequence allows searches for phylogenetic relationships, gene cloning and expression of immunorelevant molecules. Acidians lack of the pivotal components of the vertebrate recombinatory adaptive immunity, i.e., MHC, TCRs and dimeric immunoglobulins. However, bioinformatic sequence analyses recognized genic elements indicating the essential features of the Ig superfamily and ancestor proto-MHC genes, suggesting a primitive pre-duplication and pre-recombination status. C. intestinalis genes for in…
Live imaging of developmental processes in a living meristem of Davidia involucrata (Nyssaceae).
2014
Morphogenesis in plants is usually reconstructed by scanning electron microscopy and histology of meristematic structures. These techniques are destructive and require many samples to obtain a consecutive series of states. Unfortunately, using this methodology the absolute timing of growth and complete relative initiation of organs remain obscure. To overcome this limitation, an in vivo observational method based on Epi-Illumination Light Microscopy (ELM) was developed and tested with a male inflorescence meristem (floral unit) of the handkerchief tree Davidia involucrata Baill. (Nyssaceae). We asked whether the most basal flowers of this floral unit arise in a basipetal sequence or, altern…
Hybrid evolutionary multi-objective optimization with enhanced convergence and diversity

Opportunità attive: Palermo mia
2014
Le questioni poste nel saggio portano a considerare la dinamica contemporanea come il luogo d’elaborazione di un concetto interpretativo dell’architettura, intesa come servizio/funzione nei confronti delle mutevoli necessità dell’utenza, elemento di indirizzo strategico nella individuazione di proposte anche sostenibili. Un pretesto, questo, per parlare del progetto e spingersi oltre, anche solo di poco nel luogo ‘rassicurante’ depositario dell’identità, delle abitudini e delle emozioni negli “Interni” del nostro quotidiano.
Glochidia Infection of Endemic Fishes from Lake Prespa, N. Macedonia
2022
Large freshwater mussels (Unionida) are long-lived, have large bodies, and produce thousands to millions of larvae (glochidia) that usually must attach to host fish tissue to complete their life cycle. This is an obligate parasitic stage of mussel larvae. However, less than one in onemillion find a suitable host and survive. The degree of host specificity varies among unionid species, from specialists that can successfully parasitize only one or a few closely related fish species to generalists that can complete development on a taxonomically broad range of fish species. In addition, freshwater mussels are among the most threatened groups of animals. This is due to habitat destruction, the …
Järjestetty avioliitto – monta tapaa avioitua
2020
Järjestettyjen avioliittojen monimuotoisuus on ollut varsin vähän esillä suomalaisessa mediassa ja julkisessa keskustelussa. Keskustelu niistä on ylipäätään ollut suppeaa, ja keskittynyt lähinnä pakkoavioliittoihin. Vaikka muissa Pohjoismaissa julkinen keskustelu on ollut vilkkaampaa kuin Suomessa, käsitys järjestetyistä avioliitoista on pysynyt melko yksiulotteisena. Järjestettyä avioliittoa ja pakkoavioliittoa on esimerkiksi käytetty toisilleen rinnasteisina ja keskenään vaihtokelpoisina käsitteinä. Rinnastus on ongelmallinen, sillä se voi johtaa kaikkien järjestetyiksi luokiteltavien avioliittojen stigmatisointiin. Rinnastuksessa ei myöskään tunnisteta järjestettyjen avioliittojen sisäis…
The transcriptome analysis of Strongyloides stercoralis L3i larvae reveals targets for intervention in a neglected disease.
2012
Background: Strongyloidiasis is one of the most neglected diseases distributed worldwide with endemic areas in developed countries, where chronic infections are life threatening. Despite its impact, very little is known about the molecular biology of the parasite involved and its interplay with its hosts. Next generation sequencing technologies now provide unique opportunities to rapidly address these questions. Principal Findings: Here we present the first transcriptome of the third larval stage of S. stercoralis using 454 sequencing coupled with semi-automated bioinformatic analyses. 253,266 raw sequence reads were assembled into 11,250 contiguous sequences, most of which were novel. 8037…
