Localized expression of Strim1, a novel member of the TRIM-containing family, guides the skeletal morphogenetic program of the sea urchin embryo
2011
The building of the skeleton in the indirect developing sea urchin embryo is a complex morphogenetic process that is executed by the Primary Mesenchyme Cells or PMCs (Ettensohn et al, 1997; Wilt 2002). It is well known that the PMCs acquire most of the positional and temporal information from the overlying ectoderm for skeletal initiation and growth (Armstrong 1993; Cavalieri et al, 2003; Röttinger et al, 2008). In this study, we analyze the function of a novel gene, encoding for a tripartite motif-containing (TRIM) protein denoted strim1, that adds up to the list of genes constituting the epithelial-mesenchymal signaling network. We show that strim1 is expressed in ectoderm regions adjacen…
Bean goose migration shows a long-term temporal shift to earlier spring, but not to later autumn migration in Finland
2023
Ilmastonmuutos vaatii eliöitä mukauttamaan perinnöllisiä tai opittuja käyttäytymismallejaan muuttuviin ympäristöolosuhteisiin. Erityisen alttiita muutoksille voi olla erilaisten habitaattien välillä muuttavat linnut, joiden selviytyminen on yhteydessä muuton onnistuneeseen ajoittamiseen. Tässä tutkimuksessa käytimme metsähanhesta (Anser fabalis) avoimeen lintutietopalveluun, Tiiraan (tiira.fi – BirdLife Suomi), kerättyjä havaintoja selvittääksemme, onko lajin muuton ajoituksessa tapahtunut muutosta viimeisten 40 vuoden aikana. Lisäksi selvitimme ajoituksen yhteyttä muuton aikaiseen suursäätilaan käyttämällä Pohjois-Atlantin suursäätilaa kuvaavaa NAO-indeksiä. Tutkitulla ajanjaksolla 1978–20…
The early careers of the second generations: a double ethnic penalty?
2016
International audience; Young people from North African origin have greater difficulty in finding employment than their counterparts of French origin. And once they do manage to find employment, their jobs tend to be of lower quality. Thus they appear to suffer from a double penalty linked to their origins which, aggravated by the crisis, does not seem to abate over time.
Age and Acculturation: The Host Language Proficiency of Immigrants in Finland
2010
Tämän proseminaarityön tarkoituksena oli tutkia, miten maahanmuuttajan akkulturaation taso ja maahanmuuton aikainen ikä vaikuttavat saavutettuun suomen kielen osaamistasoon. Lisäksi tutkimuksen avulla yritettiin löytää mahdollisia eroja pakolaisten ja vapaaehtoisten maahanmuuttajien suomen kielen oppimiseen vaikuttavien asioiden välillä. Tutkimuksen tarkoituksena oli täydentää aikaisempaa tutkimusta maahanmuuttajien isäntäkielen oppimisesta, koska aiempi tutkimus on keskittynyt lähes ainoastaan maihin, joiden pääkielenä käytetään englantia. Viitekehyksenä käytettiin lähinnä kahta eri tutkimusta, joista toisessa käytetty kyselylomake toimi myös tämän tutkimuksen kysymyslomakkeen pohjana. L…

‘‘This is my home, too’’: Migration, spectrality and hospitality inRoberta Torre’s Sud Side Stori (2000)
2011
The article explores Roberta Torre’s film Sud Side Stori (2000), an extravagant Italian re-vision of Romeo and Juliet set in the Sicilian city of Palermo which displays awareness of the global circulation of the story of the two ‘‘star-crossed lovers’’. In the film, which combines neo-realist cinematographic techniques with the artificial style of the musical, Shakespeare’s young lovers become Toni Giulietto, a lousy local rock singer, and Romea Wacoubo, a beautiful Nigerian prostitute who falls in love with him when she sees him standing on his balcony. Not unlike West Side Story, the inter-racial passion between Toni and Romea exacerbates pre-existing ethnic conflicts. It is opposed not o…
Mi chiamo Serban e non sono il romeno di nessuno, sono il romeno di me stesso. Pratiche di assoggettamento e soggettivazione tra pastori sardi e serv…

«I am Serban, a Romanian who does not belong to anybody, I belong to my- self». Subjugation and subjectification practices between Sardinian she- pherds and Romanian servant shepherds The article investigates the role of the Romanian paid worker in the Sardinian countryside that replaces the traditional figure of the local «servo pastore» (Sardinian servant shepherd). The focus is on the symbolic and relational ten- sion between Sardinian shepherds and Romanian salaried workers, starting from extensive ethnographic material based on participant observation and in-depth interviews. By analyzing their work practices and daily interactions as well as what the Sardinians said about the Romanian…

Skin Immunomodulation during Regeneration: Emerging New Targets
2021
Adipose-Derived Stem Cells (ADSC) are present within the hypodermis and are also expected to play a pivotal role in wound healing, immunomodulation, and rejuvenation activities. They orchestrate, through their exosome, the mechanisms associated to cell differentiation, proliferation, and cell migration by upregulating genes implicated in different functions including skin barrier, immunomodulation, cell proliferation, and epidermal regeneration. ADSCs directly interact with their microenvironment and specifically the immune cells, including macrophages and T and B cells, resulting in differential inflammatory and anti-inflammatory mechanisms impacting, in return, ADSCs microenvironment and …
Hopes and Limits of Adipose-Derived Stem Cells (ADSCs) and Mesenchymal Stem Cells (MSCs) in Wound Healing
2020
Adipose tissue derived stem cells (ADSCs) are mesenchymal stem cells identified within subcutaneous tissue at the base of the hair follicle (dermal papilla cells), in the dermal sheets (dermal sheet cells), in interfollicular dermis, and in the hypodermis tissue. These cells are expected to play a major role in regulating skin regeneration and aging-associated morphologic disgraces and structural deficits. ADSCs are known to proliferate and differentiate into skin cells to repair damaged or dead cells, but also act by an autocrine and paracrine pathway to activate cell regeneration and the healing process. During wound healing, ADSCs have a great ability in migration to be recruited rapidly…
