Event-related potentials (ERPs) were recorded from 16 healthy young (mean age 21 years) and 16 healthy old subjects (mean age 64 years), and from 11 subjects with a diagnosis of Dementia of Alzheimer Type (DAT). The task requirement was to attend to a series of visually presented words so as to respond to occasional animal names. Non-animal names repeated(More)
To identify relevant relative cerebral blood volume biomarkers from T2* dynamic-susceptibility contrast magnetic resonance imaging to anticipate glioblastoma progression after chemoradiation. Twenty-five patients from a prospective study with glioblastoma, primarily treated by chemoradiation, were included. According to the last follow-up MRI confirmed(More)
7597 Background: T cell lymphomas (TCL) generally are more aggressive and have a poorer prognosis than the corresponding B cell lymphomas. A chemotherapeutic regimen that is effective in aggressive lymphoid malignancies is HCVAD alternating with methotrexate (MTX) and cytarabine (Ara-C). Pegylated liposomal doxorubicin (DOXIL) is associated with greater(More)
BACKGROUND The benefits of endovascular repair of ruptured abdominal aortic aneurysm remain controversial, without any strong evidence about advantages in specific subgroups. METHODS An individual-patient data meta-analysis of three recent randomized trials of endovascular versus open repair of abdominal aortic aneurysm was conducted according to a(More)
Owing to its single surgical intervention, immediate implant placement has the advantage of shortening treatment time, and thus positively affects patient morbidity. According to the bone resorption pattern after tooth extraction, bone loss should be anticipated if immediate implant placement is considered. The present case report aims to present a possible(More)
PURPOSE To evaluate technical complications and failures of zirconia-based fixed prostheses supported by implants. MATERIALS AND METHODS Consecutive patients received zirconia-based single crowns (SCs) and fixed dental prostheses (FDPs) on implants in a private clinical setting between 2005 and 2010. One dentist performed all surgical and prosthetic(More)
Tazarotene is an acetylenic retinoid which is metabolised to tazarotenic acid and which binds selectively to the retinoid receptors RARβ and RARγ. The safety, toxicity and pharmacokinetics of oral tazarotene were determined over 12 weeks of treatment in 34 patients with advanced cancer. Commonly seen toxicities were mucocutaneous symptoms, musculoskeletal(More)
2022 Background: AGN 195183 is a novel retinoid that trans-activates retinoic acid receptor-α (RAR-α). In preclinical models, AGN 195183 caused less skin toxicity compared to RAR interactive agents lacking RAR-α specificity and demonstrated anti-tumor activity in breast cancer and leukemia models. We initiated a clinical trial of AGN 195183 in advanced(More)
