Abstract
Legumes maintain soil fertility thanks to their associated microbiota but are threatened by climate change that causes soil microbial community structural and functional modifications. The core microbiome associated with different chickpea and lentil genotypes was described after an unexpected climatic event. Results showed that chickpea and lentil bulk soil microbiomes varied significantly between two sampling time points, the first immediately after the rainfall and the second 2 weeks later. Rhizobia were associated with the soil of the more productive chickpea genotypes in terms of flower and fruit number. The root-associated bacteria and fungi were surveyed in lentil genotypes, considering that several parcels showed disease symptoms. The metabarcoding analysis revealed that reads related to fungal pathogens were significantly associated with one lentil genotype. A lentil core prokaryotic community common to all genotypes was identified as well as a genotype-specific one. A higher number of specific bacterial taxa and an enhanced tolerance to fungal diseases characterized a lentil landrace compared to the commercial varieties. This outcome supported the hypothesis that locally adapted landraces might have a high recruiting efficiency of beneficial soil microbes.

Abstract
Liquid hydrocarbon pipeline accidents, including leaks due to the illegal or unauthorized collection of petroleum from oil pipelines, are a widespread phenomenon that can lead to pollution that may negatively affect soil quality and plant growth. The aim of this study is to evaluate hydrocarbon uptake and accumulation in Zea mays plants grown on soil affected by spills of fossil fuels. The experiments were conducted in microcosm, mesocosm and field tests. The potential transfer of contaminants from soil to plant and their effects on plant growth were investigated. The results from both the laboratory and field experiments showed that the plants grew better in the uncontaminated soil than in the soil polluted by hydrocarbons. Despite their significantly lower aerial biomass, plants grown in contaminated soil did not show any significant differences in C > 12 concentration, either in shoots or roots, compared to the control plants. Thus, the decrease in plant yield might not be attributed to hydrocarbons accumulation in the plant tissues and may rather be due to a reduced soil fertility, which negatively affected plant growth. Under our experimental conditions, the hydrocarbons present in the contaminated soil were not absorbed by the plants and did not accumulate in plant tissue or in grains, thus avoiding the risk of them entering the food chain.

Abstract
Mercury-contaminated soils from a petrochemical plant in southern Italy were investigated to assess the phytoextraction efficiency of crop plants treated with the phytohormone, cytokinine (CK foliar treatment), and with the thioligand, ammonium thiosulfate (TS, soil application). Plant biomass, evapotranspiration, Hg uptake and distribution in plant tissues following treatment were compared. Results indicate the effectiveness of CK in increasing plant biomass and the evapotranspiration rate while TS treatment promoted soil Hg solubility and availability. The simultaneous addition of CK and TS treatments increased Hg uptake and translocation in both tested plants with up to 248 and 232% in Brassica juncea (Indian mustard) and Helianthus annuus (sunflower) respectively. B. juncea was more effective in Hg uptake, whereas H. annuus gave better response regarding plant biomass production. The effectiveness of the treatments was confirmed by the calculation of Hg phytoextraction and evaluation of labile-Hg residue in the soil after plant growth. In one growing cycle the plants subject to simultaneous CK and TS treatment significantly reduced labile-Hg pools that were characterized by the soil sequential extraction, but did not significantly affect the pseudototal metal content in the soil. Results support the use of plant growth regulators in the assisted phytoextraction process for Hg-contaminated soils.

Abstract
The influence of repeated applications of tartrate (TAR) and glutamate (GLU) at 50-mmol kg(-1) of soil on Cd, Cu, Pb, and Zn distribution between a contaminated soil and Paulownia tomentosa was investigated. TAR and GLU were applied by a single or a double dosage, the latter carried out with an interval between the two applications of thirty days. The comparison of the differences in mean amounts of metals accumulated in the whole plant at the end of single and double TAR and GLU application experiments indicated the positive effect of repeated GLU applications on the accumulation of Cu, Pb, and Zn by Paulownia tomentosa as compared to untreated controls. A similar effect was not observed for the TAR treatments. When soil treated with either TAR or GLU was compared with untreated controls, no significant effect on heavy-metal concentrations in the soil solution was observed 30 days after treatment, suggesting the absence of an increase of the long-term leaching risk of heavy metals in aquifers and surface waters due to the ligand application. A cost analysis of the treatment is also reported.

Abstract
In microcosm experiments, the use of inorganic and organic amendments has been studied as potential agents to reduce heavy metal bioavailability in an acidic soil highly contaminated by Cu, Zn and Ni, that has to be remediated by phytoremediation. The concentrations of heavy metals in the original soil (O-Soil) produced phytotoxic effects with a strong reduction in biomass yield that hinder the utilization of this technology. To overcome phytotoxicity the use of three immobilizing agents was evaluated. The results obtained showed that all the strategies decreased the mobile fractions of heavy metals in soil and increased the metal removal efficiency. In the case of Brassica juncea the best results for Zn and Ni were obtained after zeolites addition (Z-Soil) with an increase of about 6 times with respect to the value found in the O-Soil. In the case of Cu, the more efficient treatment was Ca(OH)(2) addition (Ca-Soil). The B. juncea plants accumulated Cu amounts 8 times greater than in the O-Soil. For this metal, relevant results were obtained also with compost, that increased the amount of Cu in the plants of 7 times with respect to the O-Soil. Similar results were obtained with Helianthus annuus the highest Zn and Ni accumulation was detected in the Z-Soil and compost-treated soils (C-Soil), with an increase of nearly 11 times with respect to the accumulation in the O-Soil. In the case of Cu the highest increase of total uptake was found in the C-Soil: 28 times higher than in the O-Soil. Total accumulation in Poa annua plants showed the highest removal efficiency in the Z-Soil for all metals. The values obtained increased of 4, 11 and 12 times for Cu, Zn and Ni, respectively.

Abstract
The distribution of Cd, Cu, Pb and Zn between a contaminated soil and the tree species Paulownia tomentosa was investigated in a pilot-scale assisted phytoremediation study. The influence of the addition of EDTA, tartrate and glutamate at 1, 5 and 10mM concentrations on metal accumulation by the plant and on metal mobilization in soil was evaluated. Root/shoot metal concentration ratios were in the range of 3-5 for Zn, 7-17 for Cu, 9-18 for Cd and 11-39 for Pb, depending on the type and concentration of complexing agent. A significant enhancement of metal uptake in response to complexing agent application was mainly obtained in roots for Pb (i.e. 359 mg kg(-1) for EDTA 10mM and 128 mg kg(-1) for the control), Cu (i.e. 594 mg kg(-1) for glutamate 10mM and 146 mg kg(-1) for the control) and, with the exception of glutamate, also for Zn (i.e. 670 mg kg(-1) for tartrate 10mM and 237 mg kg(-1) for the control). Despite its higher metal mobilization capacity, EDTA produced a metal accumulation in plants quite similar to those obtained with tartrate and glutamate. Consequently the concentration gradient between soil pore water and plant tissues does not seem to be the predominant mechanism for metal accumulation in Paulownia tomentosa and a role of the plant should be invoked in the selection of the chemical species taken up. Metal bioavailability in soil at the end of the experiment was higher in the trials treated with EDTA than in those treated with tartrate and glutamate, the latter not being significantly different from the control. These findings indicated the persistence of a leaching risk associated to the use of this chelator, while an increase of the environmental impact is not expected when glutamate and tartrate are applied.

Abstract
In the frame of the international SOILSAMP project, funded and coordinated by the National Environmental Protection Agency of Italy (APAT), uncertainties due to field soil sampling were assessed. Three different sampling devices were applied in an agricultural area using the same sampling protocol. Cr, Sc and Zn mass fractions in the collected soil samples were measured by k(0)-instrumental neutron activation analysis (k(0)-INAA). For each element-device combination the experimental variograms were calculated using geostatistical tools. The variogram parameters were used to estimate the standard uncertainty arising from sampling. The sampling component represents the dominant contribution of the measurement uncertainty with a sampling uncertainty to measurement uncertainty ratio ranging between 0.6 and 0.9. The approach based on the use of variogram parameters leads to uncertainty values of the sampling component in agreement with those estimated by replicate sampling approach.

Abstract
Several organic compounds of high molecular weight present in soil interact with selenium and may act as active binding agents affecting its availability in soil, and, consequently, selenium uptake by plants. This study is aimed at investigating the effects of polysaccharides on selenium speciation in soil and on selenium absorption by Lactuca sativa L. plants. Three-week-old seedlings were transplanted into pots filled with soil, and sodium selenite at rates of 1.5 and 5mgSekg(-1) of soil, or sodium selenate at a rate of 1.5mgSekg(-1) of soil were applied. Carboxymethylcellulose (CMC) was added to the soil at rates of 0, 3 and 30mgkg(-1) of soil. After 48 and 110d from transplanting plants were harvested, separated into root and shoot, and fresh and dry matter weights were recorded. Total selenium was determined in both soil and plant samples. A sequential extraction was used to investigate the different Se oxidation states and assess the availability of Se in soil after the final harvesting. Both selenite and selenate were absorbed by roots, but plants amended with Se(VI+) showed higher selenium concentration than plants amended with Se(IV+). Selenite appears to be less mobile than selenate both in soil and plants. The addition of carboxymethylcellulose to soil decreased the amount of selenium absorbed by plants. CMC interacted with Se, making it less mobile as evidenced by the increase in the insoluble fractions. The insoluble Se forms in soil may represent environmental Se sinks potentially available for plants if the substrate is re-used for subsequent growth cycles and selenium species are mobilized as a result of biological and chemical processes.

Abstract
15538 Background: Standard therapy for high risk SGC includes surgical resection with adjuvant RT, but a high risk of recurrence exists. The role of chemotherapy in this setting has not been fully defined. Methods: This limited institution pilot study evaluated the use of P/C with concurrent RT as adjuvant treatment of high risk SGC. The primary objective was to assess toxicity of this treatment in anticipation of a larger cooperative group phase II study. Eligible patients (pts.) had a Southwest Oncology Group (SWOG) performance status (PS) of 0–2 who after surgical resection of their SGC had high risk features including positive surgical margins, perineural invasion, multiple lymph node (LN) metastases, or extracapsular extension. Treatment included P = 40 mg/m2 intravenously followed by C = AUC of 2 concurrently on days 1, 8, 15, 22, 29, 36 of RT. RT consisted of a total dose of 60 Gy in 30 fractions to the primary and regional LN sites of disease. Results: Five pts. were enrolled 4 with adenoid cystic CA and 1 with high grade mucoepidermoid CA. Median age was 59 years (32–69), all with SWOG PS = 0. Four pts. completed the full 6 cycle P/C chemotherapy; all completed RT per protocol. Grade III/IV mucositis, the most common toxicity, occurred in 6 of 30 (20%) P/C cycles, leading to alteration of therapy in 1 pt. There was no reported neuropathy or significant laboratory abnormalities. Median follow up was 17.5 months (mos.); most were disease free at last follow up (13 to 37 mos.); 1 recurred at 14 mos.; this pt. accounts for the only death observed. One year survival was 100%. Conclusions: The regimen of P/C with concurrent RT, as defined, was tolerated well. Grade III/IV mucositis was the main toxicity. Based on the overall tolerability of this regimen, we believe that this postoperative combined modality therapy deserves further study in a larger cooperative group phase II trial to further define its toxicity and efficacy in high risk SGC. We thank Bristol Myers Squibb for support of this study. No significant financial relationships to disclose.

Abstract
A treatability test of phytostabilization was carried out on two soils sampled downstream a mining Italian area with Lolium italicum and Festuca arundinacea. Beside chemical content of Pb and Zn in aerial parts and in roots, also some physical parameters were determined at the end of the growth cycle of plants. Particle size distribution was analysed with a laser granulometer while cracking patterns and porosity were determined by means of image analysis. Compost, used at two rates (10%, and 30% v/v) in order to improve soil physical characteristics, always raised biomass with similar effects for both doses. The concentration of Pb and Zn in aerial parts and in roots of L. italicum and F. arundinacea decreased more than five times in presence of compost. A general lack of clear effects of both plants on soil physical parameters was noticed. Formation of more water stable aggregates, a rise of the area occupied by cracks, and new porosity formed by elongated and irregular pores were found in soil samples treated with compost.

Abstract
OBJECTIVE The purpose of this article is to review the clinicoradiographic features of lower cranial nerve sheath tumors and to outline surgical approaches that allow the safe and complete resection of these lesions. METHODS Thirteen patients with lower cranial nerve sheath tumors of the infratemporal fossa were surgically treated between 7/88 and 10/99. A retrospective chart analysis provided details pertaining to clinical manifestations, radiographic assessment, intraoperative findings, tumor histology, and postoperative results. RESULTS The most common presenting symptoms were neck pressure and voice change while submucosal palatal fullness and vocal cord paralysis were the most common presenting signs. All tumors were removed via lateral skull base approaches and the most common postoperative sequelae was dysphasia. CONCLUSION Lower cranial nerve sheath tumors of the infratemporal fossa usually reach considerable size before diagnosis because of a naturally slow growth rate in this relatively silent location. The safe surgical removal of these tumors, based on superior control of the internal carotid artery, can be achieved through the use of contemporary lateral skull base techniques.

Abstract
BACKGROUND Two-thirds of patients with squamous cell carcinomas of the head and neck (SCCHN) at diagnosis have advanced disease with projected 5-year survival rates of 30%. In those patients with distant metastatic or previously treated recurrent disease, response rate to the standard regimen of cisplatin and 5-fluorouracil is approximately 30%. The authors investigated the use of paclitaxel and carboplatin in a limited Phase II study in recurrent or metastatic SCCHN to evaluate tumor response, time to progression, survival, and toxicities of this regimen. METHODS Patients with recurrent or metastatic SCCHN not amenable to further surgical or radiation therapy were treated with 200 mg/m(2) by 3-hour infusion of paclitaxel followed by carboplatin at an area under the concentration time curve of 6 mg/mL/minute via a 20-30-minute infusion every 3 weeks. RESULTS Thirty-seven patients were enrolled. Ninety-five percent of patients had received prior surgery and postoperative radiotherapy. The overall response rate was 27% (95% confidence interval, 13-41%) with 1 complete and 9 PRs. Median survival of all patients was 4.9 months, and 1-year survival rate was 16%. There was a 43% response rate and 15.7-month median survival rate in patients with only distant metastatic disease and 38% response rate and a 4.5-month median survival in patients with locoregional and metastatic disease. The response rate for patients with only locoregional recurrence was 7% with a median survival of 4.8 months. Grade 3-4 myelotoxicity occurred in 24% of cycles administered. There were two treatment-related deaths due to neutropenic fever and one additional death on study may have been caused by treatment-induced thrombocytopenia. CONCLUSIONS The combination of paclitaxel and carboplatin is significantly myelotoxic and ineffective in patients with previously treated locoregionally recurrent SCCHN, whereas it deserves further evaluation in those patients with distant metastatic disease alone. In those patients with locoregional disease, other more innovative treatments are needed.

Abstract
A xenogeneic human head and neck squamous cell carcinoma (HNSCC) model in immunocompetent mice was evaluated for its requirement of cyclosporine for progressive tumor growth. Tumor growth and T cell functions were assessed in mice receiving cyclosporine treatment for various lengths of time. Tumor cells were injected s.c. on day 1 and cyclosporine was injected i.p. daily on days 1, 1-7, 1-14, 1-21, or for the entire 28 days of tumor growth. All mice developed tumors. These tumors were confirmed to be squamous carcinomas of human origin histologically and by positive staining for human MHC class I antigen expression. Tumors were largest in mice that received cyclosporine for days 1-21 or days 1-28. Increased tumor size was associated with increased serum levels of tumor-reactive antibodies, an increased intratumoral frequency of CD4+ and CD8+ cells, but a diminished production of interleukin-2 (IL-2) by the tumor infiltrate. Also correlating with increasing tumor size was splenomegaly, a decline in the frequency, but not the absolute levels, of splenic CD4+ and CD8+ cells, and a diminished capacity to proliferate in response to concanavalin A and to be stimulated to secrete IL-2. The HNSCC tumors contributed to the immune decline since T cell functions were more depressed in the tumor bearers than in control mice receiving only cyclosporine treatment. These results demonstrate that human HNSCC tumor xenografts can grow in mice even with limited cyclosporine treatment, and that the survival of these xenografts may, in part, be due to a tumor-induced decline in select T cell functions.

Abstract
Muscle-derived factors have shown neurotrophic effects in culture, but their possible effects on the maintenance of embryonic motoneurons have not been demonstrated in vivo. Soluble extracts derived from embryonic chick muscle, or medium conditioned by chick myoblasts, were instilled onto the chorioallantoic membrane (CAM) between the 5th and 11th days of incubation. Counts of the lumbar lateral motor column (LMC) at embryonic day 12 revealed modest but significant increases (12-15%) in motoneuron number for these experimental groups as compared with control treatments. The results suggest that sustaining effects of muscle-derived factors on motoneurons may be demonstrated on the developing LMC by the simple expedient delivery via the CAM, and that these factors can modify the normal program of cell death occurring during this critical period of development.
