Erythrocyte deformability profile evaluated by laser diffractometry in patients with multiple myeloma: Re-examination of our cases.

2023

Background: Multiple myeloma is a complex pathology which represents about 10 % of all hematological neo-plasms. It can often present changes in the hemorheological profile and, in relation to this last topic, our aim is to evaluate the hemorheological profile in a group of multiple myeloma patients, with reference to erythrocyte deformability. Methods: We have examined the profile of the erythrocyte deformability in multiple myeloma enrolling 29 pa-tients; this profile, expressed as elongation index at several shear stress, has been obtained using the diffracto-metric method. Results: By comparing normal controls and MM patients, a significant decrease in erythrocyte deformability, especia…

Mitochondrial simple sequenze repeats and 12s – rRNA gene reveal two distinct lineages of Crocidura russula (Mammalia, Sorcidae)

2004

A short segment (135 bp) of the control region and a partial sequence (394 bp) of the 12S-rRNA gene in the mitochondrial DNA of Crocidura russula were analyzed in order to test a previous hypothesis regarding the presence of a gene flow disruption in northern Africa. This breakpoint would have separated northeast-African C. russula populations from the European (plus the northwest-African) populations. The analysis was carried out on specimens from Tunisia (C. r. cf agilis), Sardinia (C. r. ichnusae), and Pantelleria (C. r. cossyrensis), and on C. r. russula from Spain and Belgium. Two C. russula lineages were identified; they both shared R2 tandem repeated motifs of the same length (12 bp)…

Microevolution in the sicilian shrew crocidura sicula (mammalia, soricidae) tested by rapd-pcr fingerprinting

1997

Genetic variation in samples of the endemic Crocidura sicula living in Sicily and in two surrounding small islands, Marettimo and Ustica, was analysed by Random Amplified Polymorphic DNA fingerprinting (RAPD) and compared to morphometrics and external phenotypes. Molecular variation in the random sample of 99 DNA fragments of the Ustica shrews, showing.a melanic fur and a size-shape variation in skull morphometrics, is of comparable size to that of the of northwestern and northeastern samples Sicily (Tufanio and Madonie). In the Marettimo shrews, bicoloured (grey and white) animals like those coming from Sicily and presenting a significant reduction in body-size and skull morphometrics, mol…

The Sicilian (Crocidura sicula) and the Canary (C. canariensis) shrew (Mammalia, Soricidae): Peripheral isolate formation and geographic variation

1995

Abstract The skull and mandible morphometrics of two insular and endemic taxa (C. sicula and C. canariensis) from the Sicilian and Canary archipelagos, both having exactly the same karyotype were analysed by principal component and canonical variate analyses and related multivariate techniques. Information available in the literature was also employed to obtain a better approach to the systematics relationships in this taxon. Specimens of C. suaveolens, C. leucodon, C. whitakeri and C. russula from the Mediterranean, and C. esuae from the Pleistocene of Spinagallo (Sicily) were used as references. The results of multivariate analyses of the metric and non‐metric characters of the skull and …

Microvascular angina in diabetic patients with uninjured coronary arteries

2012

Received 14 March 2012; Accepted 26 July 2012 Abstract: Aims: The study aims at the evaluation, of patients with chest pain and uninjured coronary arteries, and the impact of diabetes mellitus on coronary microcirculation. Moreover we want to verify whether a correlation between myocardial scintigraphy results and coronary angiography or not. Methods: The study population included 316 patients (173 males,143 females) with uninjured coronary arteries. Patients with chest pain (208) were divided into two populations: diabetics (72) and non-diabetics (136).We compared 66 patients with a myocardial scintigraphy with results of angiographic indexes. On angiographic images we evaluated, on the th…

Subplate Cells: Amplifiers of Neuronal Activity in the Developing Cerebral Cortex

2009

Due to their unique structural and functional properties, subplate cells are ideally suited to function as important amplifying units within the developing neocortical circuit. Subplate neurons have extensive dendritic and axonal ramifications and relatively mature functional properties, i.e. their action potential firing can exceed frequencies of 40 Hz. At earliest stages of corticogenesis subplate cells receive functional synaptic inputs from the thalamus and from other cortical and non-cortical sources. Glutamatergic and depolarizing GABAergic inputs arise from cortical neurons and neuromodulatory inputs arise from the basal forebrain and other sources. Activation of postsynaptic metabot…

Electroless synthesis of lepidocrocite (γ-FeOOH) nanotubes in ion track etched polycarbonate templates

2012

In this study, we describe the electroless synthesis of lepidocrocite (γ-FeOOH) nanotubes produced in ion track etched polycarbonate foils. The foils act as templates after they had been irradiated with heavy ions to produce latent tracks that were etched with a desired diameter. Templates are used to fabricate shape formed 1D nanostructures in general. The synthesis of lepidocrocite nanotubes was carried out in a simple two-step method: firstly, particles were formed by precipitation in aqueous solution; secondly, nanotubes were produced by the deposition of the particles inside the nanochannels of the polycarbonate template. Solvent effects were considered to achieve homogeneous growth re…

Blood flow and oxygenation status of human tumors. Clinical investigations.

1999

There is a large body of evidence suggesting that blood flow and oxygenation of human tumors are important research topics which may explain, in particular, resistance to radiation and to many antineoplastic drugs, which can limit the curability of solid tumors by radiotherapy and chemotherapy.This manuscript reviews the clinical investigations which have been performed regarding blood flow and oxygenation status of human tumors in radiation oncology.The possible uses and limitations of the prognostic significance and the changes under therapy measuring blood flow and oxygenation in human tumors were discussed. In addition, several approaches were summarized, which can improve the microvasc…
