Heterogeneous phenotype of human glioblastoma: in vitro study.

Glioblastomas (GBMs) are the most lethal primary brain tumours. Increasing evidence shows that brain tumours contain the population of stem cells, so-called cancer stem cells (CSCs). Stem cell marker CD133 was reported to identify CSC population in GBM.

Protective effects of polydeoxyribonucleotides on cartilage degradation in experimental cultures.

The capacity of cartilage self-regeneration is considered to be limited. Joint injuries often evolve in the development of chronic wounds on the cartilage surface. Such lesions are associated with articular cartilage degeneration and osteoarthritis.

Glioblastoma cancer stem cells: heterogeneity, microenvironment and related therapeutic strategies.

Glioblastoma Multiforme (GBM) is an incurable malignancy. GBM patients have a short life expectancy despite aggressive therapeutic approaches based on surgical resection followed by adjuvant radiotherapy and concomitant chemotherapy. Glioblastoma growth is characterized by a high motility of tumour cells, their resistance to both chemo/radio-therapy, apoptosis inhibition leading to failure of conventional therapy.

Expansive Masses Arising From The Clivus: The Role Of FDG-PET/CT In The Metabolic Assessment Of Skeletal Lesions.

A patient with neurological symptoms underwent CT scan that showed a sellar and suprasellar mass with bone erosions, involving especially the clivus and the right petrous apex. The first diagnostic hypothesis was chordoma in relation to the mass position. The MRI showed a solid well-enhancing mass; moreover another circumscribed lesion, with similar signal pattern, was found in the left mandibular condyle.
