Interregional mobility, socio-economic inequality and mortality among cancer patients

2020

This paper investigates 3-years mortality after discharge in patients residing in Sicily (Italy) diagnosed with cancer among: colon, stomach, liver, and lungs, between 1/1/2010 - 31/12/2011. The effect of mobility and socio-economic status on mortality is evaluated through survival analysis approach. Results shows that out-of-region hospitalization is associated with higher survival time; no association of mortality with socio-economic status appears. The extent of patients’ mobility, and its relation with mortality raises regional policy considerations

TRAIL acts synergistically with iron oxide nanocluster-mediated magneto- and photothermia

2019

International audience; Targeting TRAIL (Tumor necrosis factor (TNF)-Related Apoptosis-Inducing Ligand) receptors for cancer therapy remains challenging due to tumor cell resistance and poor preparations of TRAIL or its derivatives. Herein, to optimize its therapeutic use, TRAIL was grafted onto iron oxide nanoclusters (NCs) with the aim of increasing its pro-apoptotic potential through nanoparticle-mediated magnetic hyperthermia (MHT) or photothermia (PT). Methods: The nanovector, NC@TRAIL, was characterized in terms of size, grafting efficiency, and potential for MHT and PT. The therapeutic function was assessed on a TRAIL-resistant breast cancer cell line, MDA-MB-231, wild type (WT) or T…

Amphoteric, prevailingly cationic L-arginine polymers of poly(amidoamino acid) structure: Synthesis, acid/base properties and preliminary cytocompati…

2013

A linear amphoteric poly(amidoamino acid), L-ARGO7, is prepared by Michael-type polyaddition of L-arginine with N,N′-methylenebisacrylamide. Chain-extension of acrylamide end-capped L-ARGO7 oligomers with piperazine leads to high-molecular-weight copolymers in which L-arginine maintains its absolute configuration. Acid/base properties of L-ARGO7 polymers show isolectric points of ≈10 and positive net average charges per repeating unit at pH = 7.4 from 0.25 to 0.40. These arginine-rich synthetic polymers possibly share some of the unique biological properties of polyarginine cell-permeating peptides. In vitro tests with mouse embryo fibroblasts balb/3T3 clone A31 show that L-ARGO7 polymers a…

The temporal variation in Siberian flying squirrel (Pteromys volans) population size

2011

Human land use causes declines of natural populations, for example, by loss of habitat area. Additionally, habitat fragmentation can cause the population size to decline more than is expected based on the area lost. Some ecological processes, such as demographic stochasticity and Allee effect, can expose already small populations to further decline. The endangered Siberian flying squirrel (Pteromys volans) has suffered from intensive forestry in Finland. In this thesis I estimated the size and growth rate of a local flying squirrel population living in nest boxes in Alavus using 15-year mark-recapture data. I regressed the estimated population size against habitat availability to detect rel…

Regional Disparities and Spatial Dependence of Bankruptcy in Spain

2021

Firm survival, bankruptcy, and turnaround are of great interest nowadays. Bankruptcy is the ultimate resource for a company to survive when it is affected by a severe decline. Thus, determinants of firm turnaround and survival in the context of bankruptcy are of interest to researchers, managers, and policy-makers. Prior turnaround literature has broadly studied firm-specific factors for turnaround success. However, location-specific factors remain relatively unstudied despite their increasing relevance. Thus, this paper aims to evaluate the existence of spatial dependence on the outcome of the bankruptcy procedure. Economic geography and business literature suggest that location matters an…

Delivery of proteins into living cells by reversible membrane permeabilization with streptolysin-O

2001

The pore-forming toxin streptolysin O (SLO) can be used to reversibly permeabilize adherent and nonadherent cells, allowing delivery of molecules with up to 100 kDa mass to the cytosol. Using FITC-labeled albumin, 10 5 –10 6 molecules were estimated to be entrapped per cell. Repair of toxin lesions depended on Ca 2+ -calmodulin and on intact microtubules, but was not sensitive to actin disruption or to inhibition of protein synthesis. Resealed cells were viable for days and retained the capacity to endocytose and to proliferate. The active domains of large clostridial toxins were introduced into three different cell lines. The domains were derived from Clostridium difficile B-toxin and Clo…

MutSa expression predicts a lower disease-free survival in malignant salivary gland tumors:an immunohistochemical study

2021

Appropriate DNA replication is vital to maintain cell integrity at the genomic level. Malfunction on DNA repair mechanisms can have implications related to tumor behavior. Our aim was to evaluate the expression of key complexes of the DNA mismatch-repair system MutS? (hMSH2-hMSH6) and MutS? (hMSH2-hMSH3) in a panel comprising the most common benign and malignant salivary gland tumors (SGT), and to determine their association with disease-free survival. Ten cases of normal salivary gland (NSG) and 92 of SGT (54 benign and 38 malignant) were retrieved. Immunohistochemistry was performed for hMSH2, hMSH3, hMSH6. Scanned slides were digitally analyzed based on the percentage of positive cells w…

Meaningful life and survival in urban poverty : an ethnographic study on the dimensions of deprivation and anxiety and the coping strategies of a gro…

2014

Tähän etnografiseen tutkimukseen on haastateltu seitsemää pitopalveluosuuskunnan jäsentä Addis Abebassa, Etiopiassa. Tutkimuksessa tarkastellaan haastateltavien pääasiallisia puutteen ja huolen aiheita, ja heidän henkilökohtaisia selviytymisstrategioitaan urbaanissa köyhyydessä. Kuinka ihmiset määrittelevät ja kokevat erilaiset päivittäiset puutteen ja huolen aiheensa? Mitä voimavaroja haastateltavat voivat käyttää selviytyäkseen urbaanissa köyhyydessä? Olen kytkenyt haastateltavien narratiivit Etiopiassa ja Addis Abebassa parhaillaan käynnissä olevaan yhteiskunnalliseen muutokseen hyödyntäen sekä haastatteluaineistoa että kirjallisuutta liittyen muun muassa urbaanin köyhyyden diskurssin ke…
