Rethinking special and differential treatment in the WTO

Special and differential treatment (S&D) allows differentiated treatment for developing countries within the WTO system by justifying a deviation from the most-favoured-nation obligation. Since it was incorporated into the GATT (the predecessor of the WTO) in the 1960s, S&D has played a significant role in promoting the integration of developing countries into the multilateral trading system. However, S&D is undergoing complicated and entangled discussion at the current multilateral trade negotiations, the Doha Development Agenda. There are a number of reasons to make opposing arguments in developed and developing countries, among which this paper focuses on two elements: diversification of developing countries and instability of preferential schemes. In order to overcome these problems and in order to make S&D more effective and operational, this paper considers the following alternative approaches: differentiation among developing countries applying the common but differentiated responsibility (CBDR) principle by analogy and codification of a preferential scheme as a multilateral agreement in the manner of North-South RTAs with flexibility.

Guidelines of natural zeolites characterization for acid mine drainage treatment. Case study Guayaquil, Ecuador

Zeolites constitute one of the less common groups of tectosilicates. Zeoli1es with pores between -2 to 10 A in their structures have strong sorption capacity and are widely used in industrial and municipal operations to eliminate toxic substances. One of the major environmental problems in the mining activity is the treating of acid mine drainage. In this context, it is very important to search alternatives to manage this challenge. One feasible alternative is using zeolitic tuffs. The results of the physical-chemical characterization of zeolitic tuffs are the c1ue lo continue or not with deeper analysis and tests 01 acid mine drainage treatments. The guidelines to reach this purpose are the main goal of this work. Zeolite 1uff samples (named as XB_01 and XB_02) studied in this work were laken rn the Late Cretaceous Coastal Cayo Arch Ecuador, specifically in the Guaraguao River, showing the most important characteristics of heulandite zeolitic tuffs. X-ray powder diffraction (XRD) tests were developed in order to confirm that the samples belong to the heulandite-type zeoli1ic tuffs. Additionally, Thermogravimetric analysis (TG), Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and X-ray fluorescence (XRF) of the samples was necessary in order to define the Si/Al ratio and the main mineralogical phases. The XB_01 sample shows a higher ratio Si/Al than XB_02 sample. The cation exchange capacity est was the fundamental step to define the potentiality of the zeolite to use in acid mine drainage treatment Three methodologies were employed to determine the cation exchange capacity. The Cuban standard 626 and the ammonium exchange methodologies reflect results more consistent with each other. This is the starting point to continue with deeper studies such as breakthrough curves for heavy metal ions found in acid mine waters.

Saline Stress Alters the Temporal Patterns of Xylem Differentiation and Alternative Oxidase Expression in Developing Soybean Roots1

We conducted a coordinated biochemical and morphometric analysis of the effect of saline conditions on the differentiation zone of developing soybean (Glycine max L.) roots. Between d 3 and d 14 for seedlings grown in control or NaCl-supplemented medium, we studied (a) the temporal evolution of the respiratory alternative oxidase (AOX) capacity in correlation with the expression and localization of AOX protein analyzed by tissue-print immunoblotting; (b) the temporal evolution and tissue localization of a peroxidase activity involved in lignification; and (c) the structural changes, visualized by light microscopy and quantified by image digitization. The results revealed that saline stress retards primary xylem differentiation. There is a corresponding delay in the temporal pattern of AOX expression, which is consistent with the xylem-specific localization of AOX protein and the idea that this enzyme is linked to xylem development. An NaCl-induced acceleration of the development of secondary xylem was also observed. However, the temporal pattern of a peroxidase activity localized in the primary and secondary xylem was unaltered by NaCl treatment. Thus, the NaCl-stressed root was specifically affected in the temporal patterns of AOX expression and xylem development.

B-cell activation by crosslinking of surface IgM or ligation of CD40 involves alternative signal pathways and results in different B-cell phenotypes.

Treatment of small resting B cells with soluble F(ab')2 fragments of anti-IgM, an analogue of T-independent type 2 antigens, induced activation characterized by proliferation and the expression of surface CD5. In contrast, B cells induced to proliferate in response to thymus-dependent inductive signals provided by either fixed activated T-helper 2 cells or soluble CD40 ligand-CD8 (CD40L) recombinant protein displayed elevated levels of CD23 (Fc epsilon II receptor) and no surface CD5. Treatment with anti-IgM and CD40L induced higher levels of proliferation and generated a single population of B cells coexpressing minimal amounts of CD5 and only a slight elevation of CD23. Anti-IgM- but not CD40L-mediated activation was highly sensitive to inhibition by cyclosporin A and FK520. Sp-cAMPS, an analogue of cAMP, augmented CD40L and suppressed surface IgM-mediated activation. Taken together these results are interpreted to mean that there is a single population of small resting B cells that can respond to either T-independent type 2 (surface IgM)- or T-dependent (CD40)-mediated activation. In response to different intracellular signals these cells are induced to enter alternative differentiation pathways.

An un-mounted horse care group for children and youth with an Autism Spectrum Disorder: Recommendations for program development and treatment intervention

Equine Assisted Activities and Therapies (EAAT) including Therapeutic Horseback Riding (THR) and un-mounted equine assisted activities are interventions aimed at improving the daily functioning and success of individuals with disabilities, including those with an autism spectrum disorder (ASD). While THR is frequently utilized as a treatment intervention for children with ASD, there are many limitations (individual's weight, horse health, weather, physical limitations, health conditions, etc.) that prevent this population from participating in mounted programs. Un-mounted equine assisted activities are often utilized as an alternative, but they are not informed by empirical research or a standardized treatment model. This paper provides a comprehensive review of the literature for EAAT including un-mounted programs, examination of organizational guidelines as they apply to un-mounted programs, and consultation with program directors regarding current practices in the field, and finally it establishes recommendations for the development of a standard curriculum that would strengthen un-mounted horse care group programs serving children with ASD.

Cross-Disciplinary Collaboration Behavior of Practitioners in the Treatment of Anxiety Disorders

Current research on the collaborative behaviors of conventional and alternative health care providers for the treatment of anxiety is lacking. While there are multiple studies looking at alternative health care integration into primary care, none of them look at anxiety specifically. The purpose of this paper is to provide a preliminary exploration of possible barriers to collaboration between conventional and alternative health care providers for the treatment of anxiety. Quantitative data on collaboration behavior patterns were obtained with an anonymous survey. Data from the surveys were analyzed using a chi-square analysis. Along with these numerical data narrative data from the survey and interviews were collected in order to assess beliefs about the barriers to collaboration from different health care providers. The results indicate that conventional providers collaborate the least with alternative providers and alternative providers collaborate the least with conventional providers. The descriptive results regarding the barriers to collaboration from the study illustrated a common theme, specifically, the lack of education of conventional providers on alternative health care practices on anxiety. This is an exploratory study: therefore it would be beneficial for future researchers to look deeper into the beliefs of health care providers on the barriers to collaboration, possibly identifying the specific barriers to collaboration for each type of healthcare provider.

Botulinum Toxin as an Alternative to Treat the Spasm of the Near Reflex

We describe the case of an eight-year-old girl with complaints of headaches and blurred vision (uncorrected visual acuity: 0.1 decimal) that showed on examination miotic pupils, pseudomyopia, no ocular motility restrictions, and no associated neurological disease. After initial treatment with cyclopentolate for two months, pseudomyopia persisted with an intermittent and variable esotropia. Spectacles of +1 both eyes and atropine 1% one drop daily were then prescribed. The situation improved and remained stable for several weeks, with pseudomyopia and esotropia reappearing later. Finally, botulinum toxin (2.5 iu Botox®) was injected in the medial rectus muscle on two occasions and a visual therapy program based on the stimulation of fusional divergence, diplopia, and stereopsis consciousness was recommended. This prescription was combined with the use of atropine during the first few weeks. Orthotropia and corrected distance visual acuity of 1.0 were found three months after treatment. The evolution and clinical results of this case report suggest that botulinum toxin in combination with other therapeutic alternatives may be useful in the treatment of spasm of the near reflex.

Use of complementary and alternative medicine and quality of life: changes at the end of life

The purpose of this study was to compare the physical, psychological and social dimensions associated with quality-of-life outcomes over the last year of life, between advanced cancer users and nonusers of complementary and alternative medicine. One hundred and eleven patients were identified through Queensland Cancer Registry records, and followed up every four to six weeks until close to death using standardized protocols. Outcome measures were symptom burden, psychological distress, subjective wellbeing, satisfaction with conventional medicine and need for control over treatment decisions. At the initial interview, 36 (32%) participants had used complementary/ alternative medicine the previous week; mainly vitamins, minerals and tonics and herbal remedies. Among all participants, 53 (48%) used at least one form of complementary/ alternative medicine over the study period. Only six (11%) visited alternative practitioners on a regular basis. Overall, complementary/ alternative medicine users reported higher levels of anxiety and pain, less satisfaction with conventional medicine and lower need for control over treatment decisions compared with nonusers. These differences tend to change as death approaches. A more rigorous assessment of complementary/ alternative medicine use, psychological distress, pain and subjective wellbeing among patients with advanced cancer is needed in the clinical setting.

A prospective study of the use of alternative therapies by men with localized prostate cancer

Although the use of alternative therapies is highly prevalent amongst men with prostate cancer, research about the predictors of such use is limited. The current study aimed to describe prospectively the use of alternative therapies by men diagnosed with localized prostate cancer and identify predictors of alternative therapy use. In all, 111 men newly diagnosed with localized prostate cancer (93% response) were recruited to the study prior to treatment. Men's use of alternative therapies and psychological variables including: psychological distress, orientation to health care, decisional conflict, and health locus of control, were assessed at three time points-(1) before treatment; (2) 2 months after completion of treatment; and (3) 12 months after completion of treatment. Demographic information was also obtained. The percentage of men using alternative therapies was 25, 17 and 14% before treatment, 2 and 12 months after treatment, respectively. In general, the most commonly used therapies were dietary changes, vitamins and herbal and nutrient remedies. Alternative therapy use was not related to final treatment choices. Before treatment, men who used alternative therapies were more uncertain about prostate cancer compared to men who were not using these therapies. Men who were using alternative therapies 12 months after treatment were less psychologically distressed that men who were not using these therapies. Health locus of control and orientation to health care were not found to be related to men's use of alternative therapies. In conclusion, men's use of alternative therapies after localized prostate cancer varied across time in terms of the incidence of use, the types of therapies used, and the psychological correlates of therapy use. Informational support that targets uncertainty about prostate cancer may assist men at diagnosis who are considering alternative therapy use. The potential for alternative therapies to have a supportive function in patient care requires further investigation. (C) 2003 Elsevier Ireland Ltd. All rights reserved.

Efficacy of speech pathology management for chronic cough: a randomised placebo controlled trial of treatment efficacy

Background: Chronic cough that persists despite medical treatment may respond to speech pathology intervention, but the efficacy of such treatment has not been investigated in prospective randomised trials. The aim of this study was to determine the efficacy of a speech pathology intervention programme for chronic cough. Methods: A single blind, randomised, placebo controlled trial was conducted in 87 patients with chronic cough that persisted despite medical treatment. Patients were randomly allocated to receive either a specifically designed speech pathology intervention or a placebo intervention. Participants in both groups attended four intervention sessions with a qualified speech pathologist. Results: Participants in the treatment group had a significant reduction in cough (8.9 to 4.6, p, 0.001), breathing (7.9 to 4.7, p < 0.001), voice (7.3 to 4.6, p < 0.001) upper airway (8.9 to 5.9, p < 0.001) symptom scores and limitation (2.3 to 1.6, p < 0.001) ratings following intervention. There was also a significant reduction in breathing (6.8 to 5.6, p=0.047), cough (7.6 to 6.3, p=0.014), and limitation ( 2.3 to 2.0, p=0.038) scores in the placebo group, but the degree of improvement was significantly less than in the treatment group (p < 0.01). Clinical judgement of outcome indicated successful ratings in 88% of participants in the treatment group compared with 14% in the placebo group ( p, 0.001). Conclusion: Speech pathology is an effective management intervention for chronic cough which may be a viable alternative for patients who do not respond to medical treatment.

Treatment of falciparum malaria in the age of drug-resistance

The growing problem of drug resistance has greatly complicated the treatment for falciparum malaria. Whereaschloroquine and sulfadoxine/ pyrimethamine could once cure most infections, this is no longer true and requiresexamination of alternative regimens. Not all treatment failures are drug resistant and other issues such asexpired antimalarials and patient compliance need to be considered. Continuation of a failing treatment policyafter drug resistance is established suppresses infections rather than curing them, leading to increasedtransmission of malaria, promotion of epidemics and loss of public confidence in malaria control programs.Antifolate drug resistance (i.e. pyrimethamine) means that new combinations are urgently needed particularlybecause addition of a single drug to an already failing regimen is rarely effective for very long. Atovaquone/proguanil and mefloquine have been used against multiple drug resistant falciparum malaria with resistance toeach having been documented soon after drug introduction. Drug combinations delay further transmission ofresistant parasites by increasing cure rates and inhibiting formation of gametocytes. Most currentlyrecommended drug combinations for falciparum malaria are variants of artemisinin combination therapy wherea rapidly acting artemisinin compound is combined with a longer half-life drug of a different class. Artemisininsused include dihydroartemisinin, artesunate, artemether and companion drugs include mefloquine, amodiaquine,sulfadoxine/ pyrimethamine, lumefantrine, piperaquine, pyronaridine, chlorproguanil/dapsone. The standard ofcare must be to cure malaria by killing the last parasite. Combination antimalarial treatment is vital not only tothe successful treatment of individual patients but also for public health control of malaria.
