The Arno River Basin(Central Italy)is affected by a considerable anthropogenic pressure due to the presence of large cities and widespread industrial and agricultural practices.In this work,26 water samples from the Arno River and its main tributaries were analyzed to assess the water pollution status.The geochemical composition of the Arno River changes from the source(dominated by a Ca-HCO_(3) facies)to the mouth(where a Na-Cl(SO4)chemistry prevails)with an increasing quality deterioration,as suggested by the Chemical Water Quality Index,due to anthropogenic contributions and seawater intrusion before flowing into the Ligurian Sea.The Ombrone and Usciana tributaries introduce anthropogenic pollutants into the Arno River,whilst Elsa tributary supplies significant contents of geogenic sulfate.The concentrations of dissolved nitrate and nitrite(up to 63 and 9 mg/L,respectively)and the respective isotopic values of𝛿15N and𝛿18O were also determined to understand origin and fate of the N-species in the Arno River Basin surface waters.The combined application of𝛿15N-NO_(3) and𝛿18O-NO_(3) and N-source apportionment modelling allowed the identification of soil organic nitrogen and sewage and domestic wastes as primary sources for dissolved NO_(3)-.The𝛿15N-NO_(2) and𝛿18O-NO_(2) values suggest that the nitrification process affects the ARB waters,thus controlling the abundances and proportion of the N-species.Our work indicates that additional efforts are needed to improve management strategies to reduce the release of nitrogenated species to the surface waters of the Arno River Basin,since little progress has been made from the early 2000s. 展开更多

Passive-roof duplexes accommodate shortening at the mountain front of many fold-and-thrust belts worldwide.These structures typically manifest at the surface by hinterland-verging backthrusts that decouple thin-skinned thrust sheets from underlying foreland-verging duplexes.Although the main fac-tors controlling the development of passive-roof duplexes have mostly been identified,some of their intrinsic characteristics are still poorly defined.These relate to their spatio-temporal relationships to thrust faults located further inland in orogens,and their ability to transport younger rocks over older ones.This study explores these issues in the Casentino-Romagna axial sector of the Northern Apennines,which expose regional forethrusts and backthrusts.Detailed field mapping and analysis of superposed tectonic structures were integrated with apatite fission-track dating for constraining the tim-ing of rock exhumation and correlated tectonic events.Collectively,the results have allowed us to inter-pret the evolution of the study area in terms of two main deformation stages.Specifically,a first,long phase(D_(1))progressed from NE-directed,in-sequence thrusting(∼18 to∼10-9 Ma)to late out-of-sequence thrusting(∼8-5 Ma).A successive deformation phase,that we refer to as D_(2)(∼4-2 Ma),con-sisted of backthrusts and associated folds that were ubiquitous and systematically overprinted onto the foreland-verging D_(1)structures.Such retrovergent structures identify a late deformation phase dom-inated by the development of passive-roof duplexes that propagated hinterlandward into the orogen up to beyond the primary watershed ridge.Orogen-scale processes controlled the evolution of forelandward D_(1)-phase thrusts,although late erosion could have played a major role by bringing the Apennine thrust wedge toward an undercritical state.The latter conditions could have contributed to keeping the out-of-sequence thrusts active,and eventually promoted the development of the D_(2)passive-roof duplexes. 展开更多

The relationship between murine IgE, IgG, and IgG1 level and birosarcoma induced by 3-Methyl-cholanthrene in NIH mice was studied. The results showed that IgE, IgG or IgGl had no significant effect on tumor incidence; the high IgE level could extend the survival time of 3-Methylcholanthrene injected mice (P<0.05) and survival time of tumor bearing mice (P<0.01), while IgG or IgGl could not. The data from this study did not show that IgE, IgG or IgGl had any significant effect on the tumor size and the tumor growth rate. The probable mechanism involved was discussed. 展开更多

The present paper reports on the experimental research done with this drug. It was found that PSP had the ability to recover hemolysin HC50, to increase the weight of the thymus, and increase the alexin of serum C3 and the IgG content of tumor bearing mice. FSP also significantly raised the pha-gocytic activity of macrophages in normal mice. PSP had a significant inhibitory effect on P38S and S180 cells. At the concentration of 1 mg/ml, PSP inhibited the proliferating activity of some human tumor call lines, such as SGC 7901, SPC, SLY and Mei. It had a direct toxic effect on SPC cells. PSP significantly inhibited the synthesis of nucleic acids of Ehrlich ascites carcinoma cells. In addition, PSP was antagonistic to the side effects of chemotherapy and radiotherapy. 展开更多

According to the Kiel classification, they were classified into 2 types. Eight patients had centroblastic/centrocytic <CB/CC) lymphomas while 2 patients and centrocytic (CC) lymphomas. After monoclonal antibody labelling, the results were consistent with those of the clinical and morphologic analyses. Of the 10 cases, 9 were B1 positive, 6 were K positive, and 4 were λ positive. In 8 cases labeled with immunoglobulin, 6 were IgGFab positive, 2 were IgM positive and 8 were IgA negative. Five cases (CB/CC 3, CC 2) were both Bl, K and IgG positive (γ K). Four cases CB/CC were both Bl and A positive. Only one case (CB/CC) was both K and IgM positive (μ K). Two cases (CB CC) were both A and IgG positive (γ λ). The results indicate that Bl, K and A are the most important markers to phenotype cutaneous B-cell lymphomas. Our findings also show a higher percentage of y K types in CGCCL as compared with Western countries. 展开更多

Studies were performed in 20 patients with breast cancer, who received 26 cycles of high-dose cisplatin (100 mg/m2, IV. drip). In twenty-five cycles of them urinary Alb, IgG and NAG showed abnormal values. The patients were divided into low-nephrotoxicity and high-nephrotoxicity groups by the degree of renal dysfunction. Thirty-five percent of the patients exhibited high-nephrotoxicity. These patients had significantly higher plasma and/ or urinary Pt peak levels during cisplatin (CP) infusion than did low-nephrotoxicity. 70 - 80% of the patients developed significant nephrotoxicity when urinary Pt peak level rose up to 40 fig/ml or plasma Pt peak level >4 μg/ml. It is quite important to reduce nephrotoxicity that urinary Pt level is controlled below 40 μg/ml and plasma Pt level <4 μg/ml. It is suggested that urine output should be maintained over 300 ml/hr during 2 hours before and after the end of infusion and >100 ml/hr during 3 days after the infusion. That may keep the nephrotoxicity of CP in less serious degree and easy to recover. 展开更多

Tunnelling with earth pressure balance-tunnel boring machine(EPB-TBM)in clayey soil requires a careful conditioning to reduce the effect of clogging and stickiness.In the last decade,many researches have been carried out to understand how to reduce these negative behaviors using conditioning agents,and different laboratory test procedures have been proposed using both powdered clay and clay chips to quantify and assess the effect of conditioning in terms of reduction of clogging and stickiness.In this paper a review of the various proposed tests is presented.Unfortunately,it can be seen that no unified assessment method on the soil conditioning is available and therefore the designers do not have consistent data on which their choices are based.The present research proposes a laboratory test methodology to study clay conditioning taking both the behavior of chips and powdered clay into account.The proposed procedure has been applied on two different clays,and the test results are presented and discussed to show how the proposed methodology could be applied. 展开更多
