The p63 protein, a member of the p53 family of nuclear transcription factors, is characterized by different capabilities of transactivating reporter genes, inducing apoptosis, and functioning as dominant-negative agent. This study evaluated the prevalence and prognostic implications of p63 immunoreactivity in 221 patients with stage I non-small cell lung carcinoma (NSCLC) and in 57 patients with stage I-IV neuroendocrine tumours (NET). The results were correlated with the tumour proliferative fraction, the accumulation of p53 protein, and with patient survival.

Improvements in small cell lung cancer (SCLC) therapy with conventional doses of drugs with or without radiotherapy have been poor, and the 5-year survival is discouraging. Since SCLC is highly sensitive to radiotherapy and chemotherapy, some studies have tried to improve survival by increasing the dose of the drugs. Within conventional ranges, dose intensity can be increased with the support of hematopoietic growth factors (G/GM-CSF) and/or shortening treatment intervals (e.

Synthesis and characterization of new thiosemicarbazones derived from natural aldehydes (1-9) have been investigated in order to develop a research program aimed at the development of compounds with antiviral, antibacterial, and antitumor properties. These substances contain both a chain with N and S nucleophilic centers with tuberculostatic activity, and an alkyl or terpenic moiety. In addition, a few nickel(II) and copper(II) complexes (10-18), derived also from the previously studied ligands, were synthesized and characterized by means of NMR and IR techniques.

Meningothelioid nodules (MNs) are not uncommon lesions of the pulmonary interstitium composed of monomorphic round to spindle cells, likely reactive in nature. Their origin is unsettled, though a derivation from arachnoid-like cells in conditions of perturbed perfusion of the pulmonary tissue has been proposed. Here we confirm the consistent occurrence of intense progesterone-receptor immunoreactivity in MNs fortuitously detected in surgical specimens of lung carcinomas.

Epithelial-myoepithelial tumors of the lung are rare neoplasms whose biological behavior and clinical course still remain to be defined. A case of epithelial-myoepithelial tumor of the lung arising from bronchial mucosa-submucosa and occurring as a polypoid lesion of the upper left bronchus in a 47-year-old man is reported. The tumor did not infiltrate the cartilaginous wall of the bronchus and showed a biphasic histological appearance with a double layering of epithelial and myoepithelial cells.

Within the context of a hospital-based newborn hearing screening program, we have studied the application of two OAE protocols (TEOAE and DPOAE) on a group of 250 well babies. The main goal of this study was to evaluate the performance of DPOAE protocol in a relatively large population sample. using a preset number of five tested frequencies, in comparison with a default TEOAE screening protocol.

Background And Purpose: Thrombosis on atherosclerotic lesions in the large extracranial arteries is the main cause of embolization in the distal cerebral circulation and thus is involved in the pathogenesis of ischemic stroke. The assessment of biological characteristics of lesions that are predictive of thrombotic complications might help in stratification of the risk for stroke but is currently imperfect.

Methods: We compared the performance of (111)In-platelet scintigraphy with blood pool subtraction, ultrasound-based tissue texture analyses, and transcranial Doppler techniques in their ability to predict the occurrence of superficial thrombosis or the presence of a lipid pool in carotid artery plaque specimens removed at the time of carotid endarterectomy in 22 patients with unilateral carotid artery stenosis of >70%.

Three new complexes of transition metals as copper, nickel and cobalt with 5-formyluracil thiosemicarbazone (H3ut) have been synthesised and characterised by single-crystal X-ray diffraction. In all compounds the ligand behaves as SNO terdentate. In the copper complex the coordination geometry is square pyramidal with the ligand lying on the basal plane and two water molecules that complete the metal environment, the nickel compound is surrounded by six donor atoms (three of the ligand, two water oxygen atoms and a chlorine atom) in an octahedral fashion, and cobalt also shows an octahedral geometry but determined only by two terdentate ligand molecules.

In view of the great psychological effect deafness has on one's social life, the scientific community has long sought the best way to define the hearing function. The development of new technologies in this field has set "early intervention" as the primary target for screening. For this reason, within the contest of a program of audiological newborn hearing screening, the Authors have used data from a selected group of 1250 newborns to (a) compare the clinical feasibility and performance of three different DPOAE protocols and (b) establish the scoring criteria defining "pass" or "fail" responses.

Thyroid transcription factor-1 (TTF-1) is a nuclear protein regulating the transcriptional activity of lung-specific genes in the normal and neoplastic bronchioloalveolar cells. It has been implicated in the normal growth and development of the lung, and the disruption of the TTF-1 locus leads to neonatal death with pulmonary hypoplasia. We evaluated retrospectively the prevalence and clinical significance of TTF-1 immunoreactivity in 222 patients with stage I non-small cell lung carcinoma (NSCLC) with a follow-up time of at least 5 years, and we investigated its relationship with other markers of tumor growth, namely cell proliferation and angiogenesis.
