Most plant viruses rely on vector organisms for their plant-to-plant spread. Although there are many different natural vectors, few plant virus-vector systems have been well studied. This review describes our current understanding of virus transmission by aphids, thrips, whiteflies, leafhoppers, planthoppers, treehoppers, mites, nematodes, and zoosporic(More)
BACKGROUND The adoption of Quality Indicators (QIs) has prompted the development of tools to measure and evaluate the quality and effectiveness of laboratory testing, first in the hospital setting and subsequently in ambulatory and other care settings. While Laboratory Medicine has an important role in the delivery of high-quality care, no consensus exists(More)
UNLABELLED Patients with severe aplastic anemia (SAA; n = 46) were studied in long-term bone marrow culture (LTBMC) systems and compared with allogeneic marrow transplant (BMT) recipients (n = 16) (within 30 days following BMT) and normal control patients (n = 12). SAA patients were divided in two groups: transfusion-dependent (Tx-D) SAA patients (group A;(More)
Relationships of an Italian isolate of tomato yellow leaf curl geminivirus from Sardinia (TYLCV-S) with its whitefly vectorBemisia tabaci were studied by means of experimental transmissions from tomato to tomato plants. TYLCV-S was confirmed to be transmitted in a persistent, circulative manner. The minimum latent period in the vector was between 17 and 20(More)
STUDY DESIGN Five cases of epidural spinal cavernous hemangioma submitted to magnetic resonance imaging and surgery were reviewed. OBJECTIVE To correlate different magnetic resonance imaging appearances of epidural spinal cavernous hemangioma with histologic findings. SUMMARY OF BACKGROUND DATA Cavernous hemangioma is an uncommon vascular malformation(More)
In 1975, Flitter et al. proposed a Doppler technique for evaluating CSF shunt patency. Owing to the presence of many false positives, a new method of investigation is proposed in order to achieve more reliable results by using the Doppler technique after air has been injected into the shunt reservoir. Ninety patients with a CSF shunt were examined. Fifty(More)
PURPOSE A new radiotherapy schedule to treat glioblastoma multiforme after surgery, combining nicotinamide and carbogen. METHODS AND MATERIALS We analyzed 36 patients with glioblastoma multiforme treated after surgery with radiotherapy, Nicotinamide and Carbogen as follows: 7 patients were treated with accelerated fractionation: two fractions/day, 1.5(More)
BACKGROUND Women suffering from recurrent urinary tract infections (rUTIs) are routinely treated for asymptomatic bacteriuria (AB), but the consequences of this procedure on antibiotic resistance are not fully known. The aim of this study was to evaluate the impact of AB treatment on antibiotic resistance among women with rUTIs. METHODS The study(More)
The aim of the present study was to examine the efficiency of different decontamination-cleaning protocols on blood-soiled catheters used for interventional cardiology. Electrophysiology and cardiac ablation disposable devices were contaminated with bacteria-spiked human blood and underwent four different pre-sterilization protocols, including a(More)
Detection of antinuclear antibodies (ANA) is a fundamental laboratory test for diagnosing systemic autoimmune diseases. Currently, the method of choice is indirect immunofluorescence (IIF) on a HEp-2 cell substrate. The goal of this study was to evaluate the diagnostic accuracy of five commercially available enzyme immunoassay (EIA) kits for ANA detection(More)
