PMID: 22466631
Psychiatriki. 2007 Jul;18(3):273-6.

Neuroleptic malignant syndrome (NMS) constitutes the most serious adverse effect of antipsychotic medications. Although it was initially described as a complication of conventional neuroleptics, atypical antipsychotic agents are also capable of inducing the syndrome. It has been suggested that...

Detailed concentration-dependent measurements of sound absorption and velocity have been performed in dexamethasone sodium phosphate (DSP) aqueous solutions in the MHz frequency range. A single well-resolved relaxation process dominates the experimental acoustic spectra following a Debye-type distribution function. The...

Primary tumor-derived factors (TDFs) act upon normal cells to generate a pre-metastatic niche, which promotes colonization of target organs by disseminated malignant cells. Here we report that TDFs-induced activation of the p38α kinase in lung fibroblasts plays a critical...

Cancers (Basel). 2021 Apr 15;13(8). doi: 10.3390/cancers13081889.

Proton therapy (PRT) is an irradiation technique that aims at limiting normal tissue damage while maintaining the tumor response. To study its specificities, the ARRONAX cyclotron is currently developing a preclinical structure compatible with biological experiments. A prerequisite is...

PURPOSE: Radiation-induced cardiotoxicity is a significant concern in thoracic oncology patients. However, the basis for this disease pathology is not well characterized. We developed a novel mouse model of radiation-induced cardiotoxicity to investigate pathophysiologic mechanisms and identify clinically targetable...

Combination of vasculature targeting, hypofractionated radiotherapy, and immune checkpoint inhibitor elicits potent antitumor immune response and blocks tumor progression.

Journal for immunotherapy of cancer

Pierini S, Mishra A, Perales-Linares R, Uribe-Herranz M, Beghi S, Giglio A, Pustylnikov S, Costabile F, Rafail S, Amici A, Facciponte JG, Koumenis C, Facciabene A.
PMID: 33563772
J Immunother Cancer. 2021 Feb;9(2). doi: 10.1136/jitc-2020-001636.

BACKGROUND: Tumor endothelial marker 1 (TEM1) is a protein expressed in the tumor-associated endothelium and/or stroma of various types of cancer. We previously demonstrated that immunization with a plasmid-DNA vaccine targeting TEM1 reduced tumor progression in three murine cancer...

Prevalence of BRCA1 and BRCA2 mutations in unselected breast cancer patients from Greece.

Hereditary cancer in clinical practice

Koumpis C, Dimitrakakis C, Antsaklis A, Royer R, Zhang S, Narod SA, Kotsopoulos J.

Hered Cancer Clin Pract. 2011 Nov 15;9:10. doi: 10.1186/1897-4287-9-10.

BACKGROUND: Inheritance of a mutation in either BRCA1 or BRCA2 accounts for approximately 5% of all breast cancer cases, but varies by country. Investigations into the contribution of BRCA mutations to breast cancer incidence in Greece have been, for...
