Toiseuden lumo : eksoottisuus ja eroottisuus revyyteatteri Punaisen Myllyn esityksissä
2014
Tutkin pro gradu -tutkielmassani millaista eksotisointia etnisyydestä ja naiseudesta luotiin suomalaisen revyyteatteri Punaisen Myllyn (1946-1967) ohjelmistossa esitysten visuaalisten yksityiskohtien (puvustus, lavastus, rekvisiitta, ruumiinkieli) avulla. Lähestyn tutkimusaihettani ensisijaisesti valokuva-aineiston pohjalta kiinnittäen huomiota siihen, kuinka puvustuksen, lavastuksen ja rekvisiitan avulla luotiin ja vahvistettiin eksoottista ja eroottista kuvastoa. Aihepiiristä (revyyteatteri, kabaree, burleski) on tehty viimeisten viiden vuoden aikana muutamia opinnäytetöitä, ja revyy- ja kabareemaailmasta, eksotismista ja visuaalisuudesta on yksittäin puolestaan kirjoitettu paljonkin.

Conductivity measurements of DNA TX tile and origami structures
2011
Tässä tutkielmassa on tutkittu kahden erilaisen itsejärjestyvän DNA-rakenteen sähkönjohtavuutta nanomittakaavassa. Ensimmäinen rakenteista on suorakaiteenmuotoinen kaksiulotteinen DNA-levy kooltaan noin 70×100 nm2 toisen ollessa selvästi kapeampi, noin 10×60 nm2. Suurin ero rakenteiden välillä on valmistusmenetelmä: isompi rakenne on valmistettu origamitekniikalla ja pienempi niin sanottua tiilimenetelmää käyttäen. Molekyylielektroniikan kannalta DNA:n sähkönjohtavuus on oleellinen asia, sillä DNA on itsejärjestäytymisominaisuuksiensa vuoksi osoittautunut hyvin lupaavaksi molekyyliksi: yksinkertaisten nanoskaalan laitteiden valmistus käyttäen DNA-pohjaisia menetelmiä on jo mahdollista.

Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Prod…
2012
Abstract: In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid b…
Systematic implementation of higher order Whitney forms in methods based on discrete exterior calculus
2022
AbstractWe present a systematic way to implement higher order Whitney forms in numerical methods based on discrete exterior calculus. Given a simplicial mesh, we first refine the mesh into smaller simplices which can be used to define higher order Whitney forms. Cochains on this refined mesh can then be interpolated using higher order Whitney forms. Hence, when the refined mesh is used with methods based on discrete exterior calculus, the solution can be expressed as a higher order Whitney form. We present algorithms for the three required steps: refining the mesh, solving the coefficients of the interpolant, and evaluating the interpolant at a given point. With our algorithms, the order of…
Merging Features from Green's Functions and Time Dependent Density Functional Theory: A Route to the Description of Correlated Materials out of Equil…
2016
We propose a description of nonequilibrium systems via a simple protocol that combines exchange-correlation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed to avoid double counting of interactions, is tested against exact results in Hubbard-type systems, with respect to interaction strength, perturbation speed and inhomogeneity, and system dimensionality and size. In many regimes, we find significant improvement over adiabatic time dependent density functional theory or second Born nonequilibrium Green's function approximations. We briefly discuss the reasons for the residual discrepancies, and directions for future work.
Spunti critici sull’aggiornamento della normativa europea in tema di qualità dell’aria
2022
This paper aims at presenting an argument in favour of the need for a prompt update of the European legislation on air quality, by taking its cue from the current situation in Italy. The paper starts by providing a definition of outdoor air pollution and by referring to the most influential Italian scientific studies on the main health risks connected. The perspective then shifts to the analysis of the relevant legislation at both European and national level in an attempt to systematically recompose the complex framework of plans and regulations adopted for the containment and prevention of outdoor pollution. In this framework, the analysis of the three infringement procedures opened agains…
Oxysterols Incorporate in Primary Porcine Retinal Pigment Epithelial Cells and Induce Inflammation and Oxidative Stress
2006
International audience; Purpose: : Aging is associated with an accumulation of cholesterol in the Bruch’s membrane. Cholesterol is prone to undergo oxidation and to generate oxysterols that have cytotoxic properties. The aim of this study was to evaluate the effects of oxysterols on cell viability, oxidative stress and inflammation and to measure oxysterol incorporation in primary porcine retinal pigment epithelial (RPE) cell cultures. Methods: : Porcine RPE cells were incubated with oxysterols (24S–hydroxycholesterol, 24OH ; 25–hydroxycholesterol, 25OH and 7–ketocholesterol, 7K) (100µg, 50µM) for 24 and 48h. Cell viability was evaluated by measuring mitochondrial succinate dehydrogenase (S…
Reactions of m-Terphenyl-Stabilized Germylene and Stannylene with Water and Methanol: Oxidative Addition versus Arene Elimination and Different React…
2015
Reactions of the divalent germylene Ge(ArMe6)2 (ArMe6 = C6H3-2,6-{C6H2-2,4,6-(CH3)3}2) with water or methanol gave the Ge(IV) insertion product (ArMe6)2Ge(H)OH (1) or (ArMe6)2Ge(H)OMe (2), respectively. In contrast, its stannylene congener Sn(ArMe6)2 reacted with water or methanol to produce the Sn(II) species {ArMe6Sn(μ-OH)}2 (3) or {ArMe6Sn(μ-OMe)}2 (4), respectively, with elimination of ArMe6H. Compounds 1–4 were characterized by IR and NMR spectroscopy as well as by X-ray crystallography. Density functional theory calculations yielded mechanistic insight into the formation of (ArMe6)2Ge(H)OH and {ArMe6Sn(μ-OH)}2. The insertion of an m-terphenyl-stabilized germylene into the O–H bond was…
UV filters: From sunscreens to human body and the environment
2007
Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…
Epigenetic siRNA and Chemical Screens Identify SETD8 Inhibition as a Therapeutic Strategy for p53 Activation in High-Risk Neuroblastoma
2017
Given the paucity of druggable mutations in high-risk neuroblastoma (NB), we undertook chromatin-focused small interfering RNA and chemical screens to uncover epigenetic regulators critical for the differentiation block in high-risk NB. High-content Opera imaging identified 53 genes whose loss of expression led to a decrease in NB cell proliferation and 16 also induced differentiation. From these, the secondary chemical screen identified SETD8, the H4K20me1 methyltransferase, as a druggable NB target. Functional studies revealed that SETD8 ablation rescued the pro-apoptotic and cell-cycle arrest functions of p53 by decreasing p53K382me1, leading to activation of the p53 canonical pathway. I…
