Il polimorfismo C4887A del gene CYP1A1 influenza il metabolismo estrogenico e la massa ossea
2004
Regulatory networks underlying mycorrhizal development delineated by genome-wide expression profiling and functional analysis of the transcription fa…
2017
Background: Ectomycorrhizal (ECM) fungi develop a mutualistic symbiotic interaction with the roots of their host plants. During this process, they undergo a series of developmental transitions from the running hyphae in the rhizosphere to the coenocytic hyphae forming finger-like structures within the root apoplastic space. These transitions, which involve profound, symbiosis-associated metabolic changes, also entail a substantial transcriptome reprogramming with coordinated waves of differentially expressed genes. To date, little is known about the key transcriptional regulators driving these changes, and the aim of the present study was to delineate and functionally characterize the trans…
Polypropeenin fysikaalisten ominaisuuksien muutokset ekstruusioprosessissa
2013
Changes in mechanical properties and reasons for twisting behaviour of thermoformed polypropylene lids is studied. The study is based on the investigation of changes in molecular weight distribution and crystallinity of isotactic polypropylene during extrusion process with different process parameters. Also the effect of additives and re-grinded material is studied. Gel permeation chromatography (GPC) was used in measurements of molecular weight distributions and crystallinities of polypropylene was measured with differential scanning calorimetry (DSC). Process parameters don't have any effect on mechanical properties of the lids but twisting behaviour diminish considerably by changing the …
Comparison of the Properties of Activated Carbons Produced in One-Stage and Two-Stage Processes
2018
Activated carbons (ACs) can be produced from biomass in a thermal process either in a direct carbonization-activation process or by first carbonizing the biomass and later activating the bio-chars into activated carbons. The properties of the ACs are dependent on the type of process used for production. In this study, the properties of activated carbons produced in one-stage and two-stage processes are considered. Activated carbons were produced by physical activation of two types of starting materials: bio chars produced from spruce and birch chips in a commercial carbonization plant and from the corresponding raw chips. The activated carbons produced were characterized regarding specific …
Étude d'inclusions végétales dans des tessons de poterie ou des matériaux de construction
2005
Vegetal inclusions embedded in clayey materials (cob, ceramic, mudbrick) are investigated by using impregnation of the porous material with a fluorescent polymer. The micro-casting of the porosity is exploited by following two ways. Sections of the treated samples are examined under UV-light, showing vegetal structures amenable to a botanical identification and quantification. Moreover, micro-casts embedded in the mineral matrix have been successfully sorted. This new application is a tool to study archaeological samples previously not amenable to the work of archaeobotanists and to expand their field of investigation.
Protein recovery as a resource from waste specifically via membrane technology : from waste to wonder
2021
Economic growth and the rapid increase in the world population has led to a greater need for natural resources, which in turn, has put pressure on said resources along with the environment. Water, food, and energy, among other resources, pose a huge challenge. Numerous essential resources, including organic substances and valuable nutrients, can be found in wastewater, and these could be recovered with efficient technologies. Protein recovery from waste streams can provide an alternative resource that could be utilized as animal feed. Membrane separation, adsorption, and microbe-assisted protein recovery have been proposed as technologies that could be used for the aforementioned protein re…
Il concetto di potestas nell'editto 'de noxalibus actionibus'. Per una ricostruzione della fase in iure del processo nossale classico
2017
Della fase in iure del processo nossale classico i testi raccolti nei titoli 2.9 e 9.4 dei Digesta Iustiniani, rubricati rispettivamente ‘Si ex noxali causa agatur, quemadmodum caveatur’ e ‘De noxalibus actionibus’, non ci tramandano una descrizione compiuta e lineare. L’abbozzo di una sintesi si può invero rinvenire in alcuni squarci della giurisprudenza severiana,1 ma non pochi passaggi restano nell’ombra, del tutto taciuti o non adeguatamente esplicitati. Spetta quindi all’interprete, come con i frammenti di un mosaico – un mosaico nella specie intricatissimo –, cercare di ordinare i vari ‘pezzi’, raccordarli logicamente fra loro e restituire, se possibile, un insieme coerente. Il compit…
Kakeksian mekanismit ja hoito
2022
Kakeksia on sairauden aiheuttama tila, jossa paino sekä luurankolihaksen ja rasvakudoksen määrä vähenevät ja toimintakyky heikkenee, eikä näitä oireita voida täysin kumota ravitsemuksen tuella. Kakeksiaa esiintyy erityisesti syöpäsairauksien yhteydessä. Se heikentää elämänlaatua, lisää kuolleisuutta ja hankaloittaa perustaudin hoitovasteen saavuttamista. Kakeksian patofysiologia tunnetaan vain osittain. Tärkeimpiä mekanismeja ovat yleistynyt tulehdusvaste, luurankolihaksen surkastuminen, rasvakudoksen aineenvaihdunnan muutokset ja hormonaalisen toiminnan häiriintyminen. Yksittäisiin tekijöihin vaikuttavat lääkitykset eivät tilan monitekijäisen patofysiologian vuoksi tehoa riittävästi, eikä …
Energie informatique et choix de matériel
1995
The choice of computers been made according to a minimax: one chooses the most powerful computer in the less powerful category. We show here that, in a simple case, if one takes into account the time of equipment utilization, this rule can be given in cause. We study then a case more complicated including some technical parameters like the case of multiprocessor machine and including other human parameters like the intensity of task submission.
DEVELOPMENT & QUALIFICATION OF BIOASSAYS FOR THE DETERMINATION OF THE BIOACTIVITY, PREDICTIVE PHARMACOKINETICS AND POTENTIAL IMMUNOGENICITY OF THERAP…
2021
The critical quality attributes of a given biotherapeutic monoclonal antibody (mAb), its molecular characterization, functional assessment and effector function analysis should be defined and profiled in detail during the life cycle of a biotherapeutic drug. In the past, this product characterization was simple and standardized. In today’s complex world of biologics, success demands a more thoughtful approach and drug developers are investing in advanced analytics much earlier in the development process. Indeed, investing in selected sophisticated and state of the art analytics in early developmental phases of a therapeutic monoclonal antibody may mitigate risks by confirming that the drug …
