Project Appraisal and Capital Investment Decision Making in the Scottish Water Industry

FINANCIAL ACCOUNTABILITY & MANAGEMENT, Issue 1 2000
Paul Coleshill
Restructuring the Scottish water industry has changed the way in which both project appraisal and capital investment decisions are performed. This article examines the project appraisal and subsequent capital investment decision in the case of a reed bed sewage treatment scheme which is compared with a more traditional scheme. Although the capital profiles of the schemes are similar there are major differences in the revenue costs. In addition, there are potential public benefits to the reed bed scheme. A comparison is made of management mechanisms in the pre-1996 water industry with that of restructured water authorities. In the pre-1996 water industry, local authorities had a broad remit which encouraged them to value these factors, in effect an implicit social account. The creation of water authorities with narrow remits and specific performance measures, constructed a framework that does not support the integration of social accounts into the decision making process. The paper demonstrates that investment appraisal is a product of the institutional framework in which the decisions are made. As that framework changes, mechanisms and measures of accountability shift in parallel. [source]


Resistant pityriasis lichenoides et varioliformis acuta in a 3-year-old boy

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2010
Successful treatment with methotrexate
Pityriasis lichenoides et varioliformis acuta (PLEVA) represents the acute clinical subtype of pityriasis lichenoides (PL) and its occurrence is relatively common during childhood. Diagnosis and treatment may sometimes pose certain difficulties. We present the recalcitrant case of a 3-year-old boy with an asymptomatic polymorphic eruption consisting of multiple, scattered, 0.5 cm, round to ovoid, erythematous papules covered in places with a fine scale, vesicles and superficial erosions with thick hemorrhagic crusts. The correlation of the clinical features with the lesional histopathology favored the diagnosis of PLEVA. No first-line treatment scheme succeeded in controlling the eruption of new lesions. The only therapeutic approach that eventually managed to cease the disease evolution was the combination of prednisolone and methotrexate. [source]

Abstract Aim:, To evaluate the overall effect of disease modifying anti-rheumatic drug (DMARD) combination therapy in daily practice. Methods:, In a retrospective study, 161 consecutive files of patients who attended regular follow-up sessions, seen from 1998, were analysed. Their data were extracted at baseline, 6 months, 1, 2, 3, 4 and 5 years. American College of Rheumatology ACR70 criteria was chosen for the evaluation of the global result. DMARD combination was methotrexate (7.5,15 mg weekly) and chloroquine (150 mg daily), with low-dose prednisolone (less than 10 mg daily). In cases of remission, methotrexate was gradually tapered, then prednisolone. Chloroquine was discontinued after 1 year if no recurrence occurred at low-dose (150 mg every other day). In cases of recurrence at any stage, the treatment scheme was stepped back. Results:, The data of 161 patients were analysed. One hundred and six were rheumatoid factor positive (RF+) (66%). ACR 70 for all patients at 6 months follow-up was 72.5% (95% CI = 7.0); at 1 year, 75.8% (95% CI = 6.7); at 2 years, 72.2% (95% CI = 7.2); at 3 years, 78.9% (95% CI = 6.6); at 4 years, 78.4% (95% CI = 6.9); and at 5 years, 70.6% (95% CI = 8.5). Conclusion:, The classical DMARD combination therapy, when used with adequate low-dose prednisolone, gave an ACR70 response from 71,79%. The efficacy of the treatment did not fade over time. RF, patients did better than RF+ patients, but the difference was not statistically significant. [source]

Please cite this paper as: Di Filippo, Monopoli, Ongini, Perretti and D'Amico (2010). The Cardio-Protective Properties of Ncx-6550, a Nitric Oxide Donating Pravastatin, in the Mouse. Microcirculation17(6), 417,426. Abstract Objective:, Determine the cardio-protective properties of a nitric oxide-releasing pravastatin (Ncx-6550), in comparison to pravastatin. Methods:, A mouse model of myocardial infarct was used assessing tissue damage both at 2 and 24 hour post-reperfusion, administering compounds both prophylactically and therapeutically. Results:, Ncx-6550 induced a significant dose-dependent (2.24,22.4 ,mol/kg i.p.) cardioprotection in the two hour reperfusion protocol. In vehicle-treated mice, infarct size (expressed as fraction of area at risk; IS/AR) was 41.2 ± 1%, and it was reduced to 22.2 ± 0.9% and 32.6 ± 0.9% following 22.4 and 6.72 ,mol/kg Ncx-6550 (p < 0.05). 22.4 ,mol/kg Ncx-6550 also increased cardiac levels of the enzyme heme oxygenase-1. Treatment of mice with pravastatin induced significant reduction of myocardial injury only at 22.4 ,mol/kg (IS/AR value: 33.7 ± 0.9%). In a 24 hour reperfusion protocol, Ncx-6550 and pravastatin were tested only at 22.4 ,mol/kg i.p. being given either one hour prior to ischemia (prophylactic protocol) or one hour into reperfusion (therapeutic protocol). With either treatment scheme, Ncx-6550 produced higher cardioprotection compared to pravastatin, as reflected also by a reduction in the incidence of lethality as well as in circulating troponin I and interleukin-1, levels. Conclusions:, These results indicate Ncx-6550 as a novel therapeutic agent with a potential for the treatment of myocardial infarct. [source]


3143: Management of iris melanomas with 125 iodine plaque radiotherapy

ACTA OPHTHALMOLOGICA, Issue 2010
BF FERNANDES
Purpose The experience with 125Iodine (I125) plaque brachytherapy in the treatment of IM at the Princess Margaret Hospital/University Health Network is the subject of the report to follow. Methods All cases of IM submitted to I125 plaque radiotherapy were included. Patients' demographic, clinical, management, and follow-up data were reviewed. Outcome measures included rates of tumor control, eye preservation, systemic metastases, and brachytherapy-related complications. Results Fourteen IMs were included in the study. All patients had blue/green irises. Mean largest basal dimension and thickness were 7.1 +/- 2.1 mm (range, 4.0 to 11.5 mm) and 2.2 +/- 0.8 mm (range, 1.0 to 3.5 mm), respectively. Ten patients (71%) had seeding and 2 (14%) had glaucoma at presentation. Median follow-up was 26.6 +/- 19.5 months (range, 6 to 72 months). Tumor control was achieved in 100% of the cases and no eye was enucleated because of radiation-induced complications. At last visit, all patients were alive and free of metastasis. Final visual acuity was the same as or better than before treatment in 9 patients (75%). Cataract was the most common complication (8; 75%), followed by persistent glaucoma (2; 17%) and anterior uveitis (1; 8%). No other significant complication was seen during the follow-up period. Conclusion Plaque radiotherapy is a safe and effective conservative treatment option for IM, although cataract is a common, yet treatable, complication. This treatment scheme circumvents an intraocular procedure and may avoid the dissemination of malignant cells, and provides a margin of safety in the treatment of clinically undetectable disease.

Membrane bioreactors vs conventional biological treatment of landfill leachate: a brief review

JOURNAL OF CHEMICAL TECHNOLOGY & BIOTECHNOLOGY, Issue 10 2004
Héctor Alvarez-Vazquez
Abstract A review of quality and biological treatment of landfill leachate is presented. Conventional ex-situ treatment normally demands multistage process treatment schemes, which may encompass both aerobic and anaerobic technologies alongside chemical precipitation and/or oxidation. This is to be contrasted with the more recent membrane bioreactor technology, which generally demands much reduced pre- and post-treatment and has a much reduced footprint compared with conventional biotreatment. Results are summarised in terms of the key determinant of COD removal for waters characterised in terms of BOD/COD ratio and age. Process operation is characterised with respect to COD strength and loading rate, hydraulic retention time and number of individual unit operations.

Old and emerging therapies in chronic hepatitis C: an update

JOURNAL OF VIRAL HEPATITIS, Issue 1 2008
M. Deutsch
Summary., The main goal of therapy in hepatitis C virus (HCV) infection is to achieve a sustained virological response currently defined as undetectable HCV-RNA in peripheral blood determined with the most sensitive polymerase chain reaction technique 24 weeks after the end of treatment. This goal is practically equivalent with eradication of HCV infection and cure of the underlying HCV-induced liver disease. The current standard in hepatitis C treatment consists in combination regimens of pegylated interferon-, (Peg-INF-,) with Ribavirin (RBV). Such treatment schemes are quite successful in patients with HCV genotypes 2 and 3 infections achieving HCV eradication rates of 75,90%. However, they are much less effective in patients with genotypes 1 and 4 infections with eradication rates ranging between 45% and 52%. Moreover, they have several, and sometimes severe, adverse effects and contraindications, further limiting their efficacy and applicability in an appreciable number of patients with chronic HCV-induced liver disease. Therefore, the need for improvement of existing therapies and for development of new effective, safe and tolerable drugs is a matter of great clinical relevance and importance. In this article, recent improvements in the current standard of therapy with IFN-, and RBV in various subsets of patients with chronic hepatitis C and in the clinical development of new emerging drugs, particularly small molecules, will be reviewed and commented. The article is divided in two main parts: (i) improvements in the standard combination therapies and schemes of approved Peg-INF-, with RBV and expectations from new interferons, interferon inducers and alternatives to RBV; (ii) new drugs for HCV in clinical development focusing mostly on specific inhibitors of HCV and less so on other drugs including immune therapies.

RF sputtered HgCdTe films for tandem cell applications

PHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 4 2004
S. L. Wang
Abstract Polycrystalline Hg1,xCdxTe films were investigated for their potential as bottom cells of a CdTe-based tandem solar cell. The films were deposited by RF sputtering from a cold pressed target containing 30% HgTe + 70% CdTe. The as-deposited films were highly resistive with (111) preferred orientation and a bandgap of ,1.0 eV. Various thermal treatment schemes were investigated under different conditions of ambient and temperature to reduce the resistivity. The film properties were analyzed using infrared transmission spectra, energy dispersive X-ray spectra and X-ray diffraction. N doped p-HgCdTe films were also prepared by reactive sputtering in a N2/Ar ambient. P-n junction solar cells were fabricated with CdS films as the heterojunction partner.

Update on the impact of Chlamydia trachomatis infection on male fertility

ANDROLOGIA, Issue 1 2004
G. F. Gonzales
Summary. With approximately 90 million cases annually, infection with Chlamydia trachomatis is the most prevalent sexually transmitted bacterial disease in the world. Considering that these infections are often asymptomatic and cause major complications like acute pelvic inflammatory disease, ectopic pregnancy, infertility or infant pneumonia, the estimated costs for diagnosis and treatment in the USA amounts to 2.2 million US dollars for each 500 cases. Therefore, there is a high need for correct, quick and cost-effective diagnosis and treatment of this urogenital tract infection. New innovative therapies provide good results with regard to efficacy and patients' compliance. The success rates of treatments are at least 95%. However, the occurrence of antibiotic resistance should not be ignored and new treatment schemes must be developed. The state-of-the-art of diagnosis and treatment of chlamydial infections as well as the pathophysiology is discussed in this review. In conclusion, infections with C. trachomatis is an important public health problem, especially in third world and developing countries, and more socio-economic studies linking secondary prevention of chlamydial infections, infertility and adverse pregnancy outcome are needed to understand more of its aetiology. In addition, diagnosis and treatment should be improved. Data in men revealed that past infections but not present infections are more related to male infertility. There is still controversial results. In future studies, function of the seminal vesicles and evaluation of the antioxidant capacity should be taken into account when role of C. trachomatis infection on male fertility is assessed.

Expression of HSP72 after ELF-EMF exposure in three cell lines,

BIOELECTROMAGNETICS, Issue 7 2007
Eric Gottwald
Abstract It has been reported that magnetic fields with flux densities ranging from µT to mT are able to induce heat shock factor, HSP72 mRNA or heat shock proteins in various cells. In this study we investigated changes in the HSP72 mRNA transcription level in three cell lines (HL-60, H9c2, and Girardi heart cells) and in the intracellular HSP72 protein content in two cell lines (HL-60 and Girardi heart cells) after treatment schemes using electromagnetic fields with a flux density of 2 µT to 4 mT, a frequency of 50 Hz and exposure times from 15 to 30 min. None of the treatments or modalities showed any significant effect on the HSP72 protein level, although HSP72 mRNA could be induced, at least to some extent, with one of the parameter combinations in all cell lines tested. Obviously, HSP72 mRNA transcription and translation are not necessarily coupled in certain cells. This leads to the conclusion that electromagnetic field effects on HSP72 mRNA levels are not indicative for downstream effects unless increased mRNA levels can be correlated with increased HSP72 protein levels as well.
