We have investigated the pattern of glutamate-like immunoreactivity in the superficial layers of the rat superior colliculus by means of postembedding immunocytochemical methods for light and electron microscopy. At the light microscopic level, labelling was faintly to moderately intense in most perikarya of the stratum zonale, stratum griseum superficiale(More)
OBJECTIVE To study the effect of systemic hyperbaric oxygenation (HBO) therapy on the healing course of nonischemic chronic diabetic foot ulcers. RESEARCH DESIGN AND METHODS From 1999 to 2000, 28 patients (average age 60.2 +/- 9.7 years, diabetes duration 18.2 +/- 6.6 years), of whom 87% had type 2 diabetes, demonstrating chronic Wagner grades I-III foot(More)
In the present study, we analyzed the cell cycle distribution of bone marrow (BM) cells in 120 untreated multiple myeloma patients using a DNA/CD38 double-staining technique at flow cytometry in which plasma cells (PCs) can be clearly discriminated from residual BM cells based on their CD38 expression. This approach allows us to determine the proliferative(More)
The characteristics and distribution pattern of retinal afferent terminals making synaptic contacts on narrow field vertical neurons in the stratum griseum superficiale of the rabbit superior colliculus were studied using the Golgi-gold substitution technique in combination with either autoradiographic or degenerative methods. At the level of light(More)
BACKGROUND Melphalan and prednisone (MP) has been the standard treatment for multiple myeloma (MM) for the last 30 years. Combination chemotherapy at conventional doses has not shown a significant prolongation of survival when compared to MP. There are few data comparing conventional chemotherapy at standard doses with conventional treatment at higher(More)
BACKGROUND Circulating soluble transferrin receptor (sTfR) has been recently found to be associated negatively with insulin sensitivity. OBJECTIVE To evaluate circulating sTfR concentration after changing insulin sensitivity in obese individuals. DESIGN Circulating sTfR concentration was evaluated after diet-induced weight loss in obese women (diet (D)(More)
The Na(+)/H(+) exchanger has been the only unequivocally demonstrated H(+)-transport mechanism in the synaptosomal preparation. We had previously suggested that a Cl(-)-H(+) symporter (in its acidifying mode) is involved in cytosolic pH regulation in the synaptosomal preparation. Supporting this suggestion, we now show that: (1) when synaptosomes are(More)
Unilateral dilatation of the lateral ventricle is a rare condition. The most common causes are tumors of the lateral ventricles or in the area of the third ventricle, acute or chronic inflammatory gliosis, cysticercosis or congenital atresia of the foramen of Monro. We report a case of asymmetrical dilatation of the lateral ventricle in an adult patient(More)
A highly specific anti-glutamate monoclonal antibody, mAb2D7, was used together with light and electron microscopy to elucidate the role played by the amino acid glutamate in the projection from the olfactory bulb to the piriform cortex in the rat. By light microscopy, glutamate-like immunoreactivity was observed in neuronal cell bodies and in the neuropil(More)
