Neurotrophin nerve growth factor (NGF) has been suggested to be involved in age-related neurodegenerative diseases, but no transgenic model is currently available to study this concept. We have obtained transgenic mice expressing a neutralizing anti-NGF recombinant antibody, in which the levels of antibodies are three orders of magnitude higher in adult(More)
We have identified a class of tau fragments inducing apoptosis in different cellular contexts, including a human teratocarcinoma-derived cell line (NT2 cells) representing committed human neuronal precursors. We have found a transition point inside the tau molecule beyond which the fragments lose their ability to induce apoptosis. This transition point is(More)
We examined the cellular distribution of mRNAs coding for the neurotrophin receptors TrkA, TrkB and p75 in the rat retina during early postnatal development. At P0 (postnatal day 0), mRNAs coding for each of the three receptors were detected in the ganglion cell layer (GCL) and in the inner plexiform layer (IPL), the latter structure essentially containing(More)
In some alcohol-related pathologies of chronic alcoholism women are more vulnerable than men. A consecutive sample of 62 chronic alcoholics was studied, 18 females and 44 males, aged between 28 and 69 years to assess the incidence and distribution of peripheral neuropathy with regard to gender. All patients underwent clinical and neurological observations,(More)
OBJECTIVE To study the relationship between lunar position and the day of delivery; to investigate the synodic distribution of spontaneous deliveries, especially in relation to the presence of a full moon. STUDY DESIGN Retrospective analysis of 1248 spontaneous full-term deliveries in three-year period (36 lunar months), setted at Department of Obstetrics(More)
Contrast enhanced ultrasound (CEUS) is an imaging technique which appeared on the market around the year 2000 and proposed for the detection of liver metastases in gastrointestinal cancer patients, a setting in which accurate staging plays a significant role in the choice of treatment. A total of 109 patients with colorectal (n = 92) or gastric cancer(More)
A consecutive sample of 76 chronic alcoholic patients was studied clinically, biochemically and electrophysiologically to assess clinical and/or subclinical signs of alcohol-related neuropathy as well as the most important and disputed risk factors for neuropathy such as age, parental history of alcoholism, nutritional status, alcoholic disease duration and(More)
AIM Analysing the effectiveness of a surgical procedure is mandatory in every modern health-care system. The aging of the population stresses the need for a good standard of care. This study tests the hypothesis that porthsmouth-physiologic operative severity score for enumeration of morbidity and mortality (P-POSSUM) and colorectal-POSSUM (CR-POSSUM) would(More)
OBJECTIVE To determine the predictive value of the "Timed Up & Go" (TUG), a validated assessment tool, on a prospective cohort study and to compare these findings to the ASA classification, an instrument commonly used for quantifying patients' physical status and anesthetic risk. BACKGROUND In the onco-geriatric surgical population it is important to(More)
Preoperative chemoradiotherapy has been widely adopted as the standard of care for stage II–III rectal cancers. However, patients with T3N0 lesions had been shown to have a better prognosis than other categories of locally advanced tumor. Thus, neoadjuvant chemoradiation is likely to be overtreatment in this subgroup of patients. Nevertheless, the low(More)
