Potential miRNAs involved in molecular pathways mediating the anticancer effects of short term starvation in breast cancer cells treated with doxorub…
2017
Background: In recent years, increasing evidences showed that several types of dietary approaches restricting food intake, including Short Term Starvation (STS), may exert a protective role against aging and other age-related pathologies as well as cancer. Interestingly, the dietary restriction showed significant anticancer effects able to prevent cancer onset, slow its progression and improve therapy response. Since recent studies showed that miRNAs may modulate sensibility/resistance to antiblastic therapy, the aim of our study was to investigate the STS-induced molecular changes in breast cancer cells treated with doxorubicin, focusing our attention on miRNA expression profile.

Deconstructing Stereotypes Through Reading Children’s Literature as Intergenerational Play: The Case of the Stepmother
2021
One of the key roles within stepfamilies, the role of stepmother has been and still is stigmatized with an aura of wickedness, produced by folk and fairy tales as well as by the media. As a review of theoretical frameworks of children’s literature indicates, there is a shortage of methodological proposals for handling such controversial topics in literary education. Thus, the objective of this chapter is to present and test a methodology for analyzing the capacity of children’s literature to shape social understanding of such intergenerational topics. This study was based on the exploration of the picture book by Gonzalez and Alberdi entitled La novia de papa tambien me quiere (My Dad’s Gir…
Pyrrolo[2,3-h]quinolinones: synthesis and photochemotherapic activity.
2003
A series of derivatives of the new ring system pyrrolo[2,3-h]quinoline-2-one was synthesized and evaluated as photoreagents toward cultured human tumor cells. Remarkable phototoxycity resulted for some derivatives, especially those bearing the phenyl group at the 7-position.
Surgical treatment of solitary sternal metastasis from breast cancer Case report
2016
Bone metastasis is a frequent and early complication of breast cancer. This case report describes a technique for a partial exeresis of the sternum and the reconstruction of the pleura with autologous dermis from the lower abdomen and the loss of substance with a myocutaneous flap.We describe the case of a 50-year old woman with a sternal excavated lesion with pathologic fracture due to an invasive adenocarcinoma, treated with a partial exeresis of the sternum and the reconstruction with a myocutaneous flap.The patient doesn't show evidence of recurrent disease and the stability of her chest well preserved.Metastatic breast cancer to the sternum, if detected early and treated aggressively, …
Cancer patients participating in a lifestyle intervention during chemotherapy greatly over-report their physical activity level: a validation study
2015
Background The short form of the International Physical Activity Questionnaire (IPAQ-sf) is a validated questionnaire used to assess physical activity (PA) in healthy adults and commonly used in both apparently healthy adults and cancer patients. However, the IPAQ-sf has not been previously validated in cancer patients undergoing oncologic treatment. The objective of the present study was to compare IPAQ-sf with objective measures of physical activity (PA) in cancer patients undergoing chemotherapy. Methods The present study was part of a 12-month prospective individualized lifestyle intervention focusing on diet, PA, stress management and smoking cessation in 100 cancer patients undergoing…
Antineoplastic Drug-Induced Cardiotoxicity: A Redox Perspective
2018
Antineoplastic drugs can be associated with several side effects, including cardiovascular toxicity (CTX). Biochemical studies have identified multiple mechanisms of CTX. Chemoterapeutic agents can alter redox homeostasis by increasing the production of reactive oxygen species (ROS) and reactive nitrogen species RNS. Cellular sources of ROS/RNS are cardiomyocytes, endothelial cells, stromal and inflammatory cells in the heart. Mitochondria, peroxisomes and other subcellular components are central hubs that control redox homeostasis. Mitochondria are central targets for antineoplastic drug-induced CTX. Understanding the mechanisms of CTX is fundamental for effective cardioprotection, without…
18F-FDG PET imaging of breast cancer : evaluation of the metabolic behaviour of the different breast cancer subtypes and prediction of the tumor resp…
2015
Positron Emission Tomography (PET) with 18Fluoro-deoxyglucose (18F-FDG) is the reference imaging examination for in-vivo quantification of the glucidic metabolism of tumour cells. It allows for the monitoring of tumour metabolic changes during chemotherapy. Breast cancer comprises several distinct genomic entities with different biological characteristics and clinical behaviours, leading to different tailored treatments. The aim of this doctoral thesis was to evaluate the relationship between the different biological entities of breast cancer and the tumour metabolic behaviour during neoadjuvant chemotherapy. We have also retrieved, among the various metabolic parameters on PET images, the …
Effect of the host plant on the immunity of a phytophagous insect : influence of grape variety on the ability of the European grapevine moth to defen…
2013
In tritrophic interactions involving phytophagous insects, host plants and natural enemies, trophic levels are highly dependent on each other. Host plant may strongly affect directly phytophagous insect and indirectly natural enemies growing on these phytophagous insects. When a natural enemy attacks a phytophagous insect, the host immune system constitutes the last chance for the host to survive to an infection. A great variation of insect immune system is generally found in populations for susceptibility to pathogens, suggesting that variable selection pressures may have shaped and driven adaptation of immune traits. This project aims to determine the influence of both host plant and natu…
The “RENAISSANCE” Trial: Effect of chemotherapy alone vs. chemotherapy followed by surgical resection on survival and quality of life in patients wit…
2017
TPS4140 Background: Recent data indicates that surgical resection may bring a benefit for select patients with metastatic gastric / esophagogastric junction cancer. However, no data obtained in randomized trials is available up to now. The current RENAISSANCE trial investigates this long-lasting question about the role of surgical intervention in limited-metastatic gastric / esophagogastric junction cancer. Methods: This is a prospective, multicenter, randomized, investigator initiated phase III trial. In this study, previously untreated patients with limited metastatic stage (retroperitoneal lymph node metastases only or a maximum of one incurable organ site that is potentially resectable…
Low parasitism rates in parthenogenetic bagworm moths do not support the parasitoid hypothesis for sex
2012
The parasite hypothesis for sex is one of the many theories that have been suggested to solve the mystery of the widespread occurrence of sex despite its high short-term costs. It suggests that sexual lineages have an evolutionary advantage over parthenogens because they can frequently generate new genotypes that are temporarily less prone to coevolving parasites. In this study, we looked for further supporting evidence for the parasite hypothesis of sex in an attempt to understand the coexistence of sexual and parthenogenetic bagworm moths (Naryciinae). The bagworm moths and their parasitoids form one of the few natural host-parasite systems where sexual and parthenogenetic hosts are appar…
