Premature aging in Werner's syndrome spares the central nervous system

Werner's Syndrome is a rare genetic disease, characterized by premature aging of many tissues and organs. We studied the brain morphology and function in two patients with Werner's syndrome to assess the possible involvement of the central nervous system in this premature aging process. The two patients (brother and sister, respectively) were studied by magnetic resonance imaging (MRI) and angiography (MRA), single photon emission computed tomography (SPECT) with (99mTc)-d,l-hexamethyl propilene amine oxime (HMPAO), positron emission tomography (PET) with 2(18F)-Fluoro-2-deoxyglucose (FDG), electroencephalography (EEG), and electromyography (EMG). Some of these investigations were also repeated after 1 year. The results of all these studies were normal. The premature aging process in patients with Werner's syndrome, while affecting most tissues, seems to spare the central nervous syste

Detection of clustered circulating tumour cells in early breast cancer

Circulating tumour cell (CTC) clusters have been proposed to be major players in the metastatic spread of breast cancer, particularly during advanced disease stages. Yet, it is unclear whether or not they manifest in early breast cancer, as their occurrence in patients with metastasis-free primary disease has not been thoroughly evaluated. In this study, exploiting nanostructured titanium oxide-coated slides for shear-free CTC identification, we detect clustered CTCs in the curative setting of multiple patients with early breast cancer prior to surgical treatment, highlighting their presence already at early disease stages. These results spotlight an important aspect of metastasis biology and the possibility to intervene with anti-cluster therapeutics already during the early manifestation of breast cancer.ISSN:0007-0920ISSN:1532-182
