Abstract
INTRODUCTION Digital screen time has been largely studied in children populations, but few have focused on children with neurodevelopmental disorders. Our main objective was to study the characteristics of use of recreational screens (television (TV) and video games), in children with neurodevelopmental disorders. SUBJECTS AND METHODS We conducted a case-control study in which children with neurodevelopmental disorders under the age of 6 were compared with controls of the same age range. We analysed TV and video game exposure through a designed questionnaire for parents that included daily time exposure, sociodemographic characteristics, home media environment, sociocultural habits, attitudes and beliefs about TV. RESULTS Sixty-one individuals with developmental and 153 controls were enrolled. Children with developmental problems spend more time watching TV than controls (124,4 ± 83,4 vs 71,5 ± 47,4 min / day p <0,001), while video game time was similar in both groups (37,6 ± 39, 6 vs 31,7 ± 32,6 min / day p = 0,138). Children with neurodevelopmental disorders began earlier to watch TV than controls. There were no relevant differences between groups in demographics, Sociocultural, environmental and attitudinal and belief variables. CONCLUSIONS Children with neurodevelopmental disorders start watching TV at an earlier age and consume more screen time than healthy children. Our findings indicate that Children with neurodevelopmental disorders are more vulnerable to screen abuse, and stress the importance to offer anticipatory guidance to their parents.

Abstract
We studied changes in chemical composition, somatic cell count, and immunoglobulin G (IgG) and M (IgM) content in red deer (Cervus elaphus) colostrum during the transition to milk at different times after parturition (<5 h, 24 h, 48 h, 2 wk, and 4 wk). The production level was higher at 2 and 4 wk of lactation than during the first day after parturition, with intermediate values at 48 h postpartum. Fat content did not vary during the study period. However, total protein and casein contents were particularly high in the initial 5 h after parturition, decreasing to approximately 50% after 24 h postpartum. Conversely, lactose concentration was low in the beginning (<5 h), increasing gradually throughout the study. Similarly, dry matter dropped during the first 24 h and then remained constant throughout the study. Urea content decreased during the study, showing a slight recovery at 4 wk. Somatic cell count was higher during the first hours after parturition and gradually decreased throughout the study period. The IgG content was higher before 5 h postpartum than at 24 h postpartum. After 5 h, the level of IgG decreased progressively until it reached 0.18 mg/mL at 4 wk of lactation. We observed a similar pattern for IgM content, but it decreased more quickly than IgG and was not detected after 2 wk. In the case of deer, milk should be considered transitional from 24 to 48 h after parturition, and samples collected after 2 wk can be considered mature milk.

Abstract
BACKGROUND Although both hospitalization and mortality due to heart failure (HF) have been widely studied, less is known about the impact of HF on disability and quality of life. AIM To assess the degree of disability and quality of life in HF patients attended at family medicine centres. DESIGN AND SETTING Cross-sectional study of a cohort of HF patients attended at family medicine centres. METHODS Disability was assessed with the WHODAS 2 questionnaire, which provides a global and six domain scores that is understanding and communication, getting around, self-care, getting along with people, life activities and participation in society. Quality of life was assessed with the Minnesota Living with Heart Failure Questionnaire, which furnishes a global and two domain scores, physical and emotional. RESULTS A breakdown of the results showed that 28% of patients had moderate disability and 16.7% had severe disability, with the most important areas affected being: life activities, 8.9% extreme disability and 30.3% severe disability; getting around, 34.6% severe disability and 2% extreme disability; and participation in society, 53.3% moderate-severe disability. Quality of life was mildly affected. New York Heart Association (NYHA) Functional Classification and sex were the major determinants of disability and quality of life. Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists were associated with better scores in the "getting around" and "life activity" domains. CONCLUSION HF patients in primary care show an important degree of disability and an acceptable quality of life.

Abstract
Background Heart failure (HF) is the leading cause of hospitalization in people over age 65. Predictive hospital admission models have been developed to help reduce the number of these patients. Aim To develop and internally validate a model to predict hospital admission in one-year for any non-programmed cause in heart failure patients receiving primary care treatment. Design and setting Cohort study, prospective. Patients treated in family medicine clinics. Methods Logistic regression analysis was used to estimate the association between the predictors and the outcome, i.e. unplanned hospitalization over a 12-month period. The predictive model was built in several steps. The initial examination included a set of 31 predictors. Bootstrapping was used for internal validation. Results The study included 251 patients, 64 (25.5%) of whom were admitted to hospital for some unplanned cause over the 12 months following their date of inclusion in the study. Four predictive variables of hospitalization were identified: NYHA class III-IV, OR (95% CI) 2.46 (1.23–4.91); diabetes OR (95% CI) 1.94 (1.05–3.58); COPD OR (95% CI) 3.17 (1.45–6.94); MLHFQ Emotional OR (95% CI) 1.07 (1.02–1.12). AUC 0.723; R2N 0.17; Hosmer-Lemeshow 0.815. Internal validation AUC 0.706.; R2N 0.134 Conclusion This is a simple model to predict hospitalization over a 12-month period based on four variables: NYHA functional class, diabetes, COPD and the emotional dimension of the MLHFQ scale. It has an acceptable discriminative capacity enabling the identification of patients at risk of hospitalization.

Abstract
BACKGROUND Renal donation leads to a risk of developing chronic kidney disease, with an incidence of 0.47%. To evaluate for its presence, formulas based on serum creatinine are used, but up to 80% of these formulas underestimate the glomerular filtration rate (GFR) in donors. The aim of this work was to confirm the highest correlation of the GFR as measured with the use of DTPA-Tc99m with the GFR as estimated by means of the formula based on serum cystatin C (CKD-EPI creatinine-cystatin C) in healthy kidney donors. METHODS In this observational, analytic, cross-sectional study, the GFR of kidney donors was determined ≥1 year after donation by means of DTPA gammagram and estimation with the use of conventional formulations and with cystatin C. RESULTS Of 112 donors, 38 (34%) were included, 20 (60%) were female, with an overall average age of 40 years, 36.5 months after donation, and body mass index of 25.5 kg/m2. Correlation with the GFR as measured by means of DTPA gammagram was better with the use of CKD-EPI cystatin C (0.402; P = .020) and CKD-EPI creatinine-cystatin (0.549; P < .001) than the conventional formulas. Linear correlation with serum cystatin C was 0.825 (P < .001; 95% confidence interval, -105.3 to -63.2) for the CKD-EPI cystatin C formula, 0.77 (P < .001; -89.9 to -48.1) for the CKD-EPI creatinine-cystatin formula, and 0.525 (P = .002; -91.1 to -23.2) for DTPA-Tc99m scintigraphy. CONCLUSIONS There is a strong correlation between estimate the GFR by equations based on cystatin C and the measurement of the GFR by DTPA-Tc99m gammagram.

Abstract
AIMS The present study analyses molecular characteristics of the locus coeruleus (LC) and projections to the amygdala and hippocampus at asymptomatic early and middle Braak stages of neurofibrillary tangle (NFT) pathology. METHODS Immunohistochemistry, whole-transcriptome arrays and RT-qPCR in LC and western blotting in hippocampus and amygdala in a cohort of asymptomatic individuals at stages I-IV of NFT pathology were used. RESULTS NFTs in the LC increased in parallel with colocalized expression of tau kinases, increased neuroketal adducts and decreased superoxide dismutase 1 in neurons with hyperphosphorylated tau and decreased voltage-dependent anion channel in neurons containing truncated tau were found. These were accompanied by increased microglia and AIF1, CD68, PTGS2, IL1β, IL6 and TNF-α gene expression. Whole-transcriptome arrays revealed upregulation of genes coding for proteins associated with heat shock protein binding and genes associated with ATP metabolism and downregulation of genes coding for DNA-binding proteins and members of the small nucleolar RNAs family, at stage IV when compared with stage I. Tyrosine hydroxylase (TH) immunoreactivity was preserved in neurons of the LC, but decreased TH and increased α2A adrenergic receptor protein levels were found in the hippocampus and the amygdala. CONCLUSIONS Complex alteration of several metabolic pathways occurs in the LC accompanying NFT formation at early and middle asymptomatic stages of NFT pathology. Dopaminergic/noradrenergic denervation and increased expression of α2A adrenergic receptor in the hippocampus and amygdala occur at first stage of NFT pathology, suggesting compensatory activation in the face of decreased adrenergic input occurring before clinical evidence of cognitive impairment and depression.

Abstract
In the context of the long-term care for older adults, informal carers play a key role. Daily competing priorities or a care-skills deficit may lead them to stress, anxiety and/or depression. The iCarer project (AAL-2012-5-239) proposes the design and implementation of a cloud-inspired personalised and adaptive platform which will offer support to informal carers of older adults with cognitive impairment. By means of a holistic approach comprising technologies and services addressing the intelligent and interactive monitoring of activities, knowledge management for personalised guidance and orientation, virtual interaction, e-learning, care coordination facilities and social network services, iCarer aims to reduce the informal carer stress and to enhance the quality of care they provide, thus improving their quality of life. The iCarer platform will be evaluated through a multi-centre non-controlled study (4 months; 48 homes located in England and in Slovenia). Currently the iCarer project is completing the development work. The evaluation trial is expected to start in August 2015.

Abstract
The role of hemopoietic stem cell transplantation (HSCT) is not well established in certain types of lymphoma, such as those with a high relapse risk or relapsing after initial therapy. New chemotherapeutic schemes and immunotherapy have improved survival of these patients. Nevertheless, there is not enough evidence regarding whether transplantation is the best therapeutic approach. Moreover, published data on long-term follow-up of high-risk lymphoma patients treated with HSCT are scarce. We analyzed 177 consecutive patients diagnosed with a high risk of relapse or with relapsed lymphoma who underwent HSCT after induction with standard chemotherapy in a tertiary academic center from 1989 to 2013. The median age was 40 years. Diagnoses were Hodgkin disease (n = 56), diffuse large B-cell lymphoma (n = 44), follicular lymphoma (n = 29), mantle cell lymphoma (n = 15), T-cell lymphoma (n = 18), and others (n = 15). Patients received either an autologous graft (n = 154) in first complete remission (1CR; n = 59) or more advanced stages (AS; n = 95), or an allogeneic graft (n = 23) in 1CR (n = 4) or AS (n = 19). In the autologous group, overall survival (OS) at 5 years was 57% and 75% in the periods 1989-2001 and 2002-2013, respectively (P = .05). Patients receiving an allogeneic graft presented an OS of 25% and 43% in the 2 periods. With a mean follow-up of 5 years (95% confidence interval 3.5-6.6), for patients receiving a transplant in 1CR, OS at 5 years was 80%, and for those receiving a transplant in AS it was 59% (P = .003). Nonrelapse mortality (NRM) at 5 years was 3.1% in the autologous group and 27.9% in the allogeneic group (P < .001). The main cause of NRM was infection (44%) in the whole cohort. All this leads to the conclusion that transplantation, as a therapeutic strategy, has shown a high long-term OS in this subgroup of patients with such a poor prognosis. OS improved over the years and reaching 1CR was a good prognostic feature. Infections were the main cause of NRM.

Abstract
Adding saffron to dairy products represents an innovative practice to introduce them to niche markets. This paper represents a contribution to this field, as few studies have evaluated the influence of this spice on general aspects and ripening parameters of cheese. In this work, pasteurized ewe milk pressed cheeses with saffron were made to study compositional, microbiological, color, textural, and sensory characteristics in relation to saffron concentration and ripening time. The main changes were observed on sensory characteristics and color. In addition, compositional, textural, and microbiological changes could be observed; among them, saffron cheeses were firmer and more elastic but less prone to fracture. A remarkable result that could lead to further studies is that saffron addition slightly slowed down growth of total and lactic acid bacteria. This resulted in a slightly lower rate of pH decrease during pressing and, as a consequence, lower salt and water content. Compositional differences were not evident by the end of the ripening period.

Abstract
Parkinson disease (PD) is a systemic disease with variegated non-motor deficits and neurological symptoms, including impaired olfaction, autonomic failure, cognitive impairment and psychiatric symptoms, in addition to the classical motor symptoms. Many non-motor symptoms appear before or in parallel with motor deficits and then worsen with disease progression. Although there is a relationship, albeit not causal, between motor symptoms and the presence of Lewy bodies (LBs) and neurites filled with abnormal α-synuclein, other neurological alterations are independent of the amount of α-synuclein inclusions in neurons and neurites, thereby indicating that different mechanisms probably converge in the degenerative process. This may apply to complex alterations interfering with olfactory and autonomic nervous systemfunctions, emotions, sleep regulation, and behavioral, cognitive and mental performance. Involvement of the cerebral cortex leading to impaired behavior and cognition is related to several convergent altered factors including: a. dopaminergic, noradrenergic, serotoninergic and cholinergic cortical innervation; b. synapses; c. cortical metabolism; d. mitochondrial function and energy production; e. oxidative damage; f. transcription; g. protein expression; h. lipid composition; and i. ubiquitin–proteasome system and autophagy, among others. This complex situation indicates that multiple subcellular failure in selected cell populations is difficult to reconcilewith a reductionistic scenario of a single causative cascade of events leading to non-motor symptoms in PD. Furthermore, these alterationsmay appear at early stages of the disease and may precede the appearance of substantial irreversible cell loss by years. These observations have important implications in the design of therapeutic approaches geared to prevention and treatment of PD.

Abstract
During the growing seasons of 2008 to 2009 and 2009 to 2010, severe outbreaks of soybean (Glycine max (L.) Merr.) frogeye leaf spot, a disease caused by Cercospora sojina Hara, occurred in several areas in Argentina (1). Two surveys were conducted in soybean fields, one in 2008 that included the provinces of Buenos Aires, Córdoba, and Santa Fe, and another that was performed in 2009 in the same provinces plus three others: Entre Ríos, Santiago del Estero, and Tucumán. In both surveys, plants presented circular lesions with reddish brown-to-gray spots and bordered by typical, narrow, reddish purple margins (3). To promote sporulation and to enable identification of the causal agent, leaves of diseased plants were collected and placed in a moist chamber for 24 h with a 12-h light cycle at 25°C. Conidia were plated on potato dextrose agar medium amended with streptomycin and were incubated at 25°C and 12 h of fluorescent light. Isolated cultures sporulated in 10 days and, on the basis of their morphology, were identified as C. sojina. A total of 147 isolates were deposited at the Culture Collection of CEREMIC (Centro de Referencia de Micología). They produced one- to nine-septate hyaline, elongate to fusiform conidia that measured 54.9 ± 16.2 × 5.7 ± 1.0 μm. Six isolates of C. sojina, each representing a province, were inoculated on a set of 12 differential soybean cultivars: Lee, Davis, Hood, Richland, Lincoln, Kent, Tracy, S 100, Palmetto, Peking, CNS, and Blackhawk (2). Fifteen plants of each differential were sprayed at V3 growth stage with a suspension of 6 × 104 conidia/ml. The test was conducted twice in a complete randomized design with three replicates. Control plants were sprayed with sterile distilled water. After inoculation, plants were placed in a greenhouse bench humidity chamber at 26 to 28°C for 72 h. Disease was rated 14 days after inoculation; plants with numerous lesions were considered susceptible and each of the 15 plants was given a score of 1. Plants with small or no lesions were classified as resistant and given a score of 0. Control plants remained healthy. The pathogen was reisolated from symptomatic plants and morphological characteristics were consistent with C. sojina. Based on the response of the differentials to each isolate and on the race designations, the isolates from Buenos Aires, Córdoba, Santa Fe, and Tucumán belong to race 11, while those from Santiago del Estero and Entre Ríos province to race 12. The finding of these two races threatening soybean cultivars in Argentina may be indicative of additional races. Thus, the incorporation of multiple resistance genes may reduce the impact of the disease on soybean. To our knowledge, this is the first report of the identification of races of C. sojina in Argentina. References: (1) M. A. Carmona et al. Plant Dis. 93:966, 2009. (2) M. A. R. Mian et al.

Abstract
In August 2010, lesions similar to those reported for target spot were observed on Nicotiana tabacum L. plants produced in float systems in Cerrillos, Salta, Argentina. Tobacco leaves with characteristic lesions were collected from different locations in Cerrillos, Salta. Symptoms ranged from small (2 to 3 mm), water-soaked spots to larger (2 to 3 cm), necrotic lesions that had a pattern of concentric rings, tears in the centers, and margins that often resulted in a shot-hole appearance. Isolation of the causal agent was made on potato dextrose agar (PDA) acidified to pH 5 with 10% lactic acid and incubated at 25 ± 2°C in darkness for 2 to 3 days. Hyphal tips were transferred to a new medium and the cultures were examined for morphological characters microscopically (3). Eight isolates were obtained. The rapid nuclear-staining procedure using acridine orange (3) was used to determine the number of nuclei in hyphal cells. Multinucleate hyphae were observed, with 4 to 9 nuclei per cell. Molecular characterization was conducted by examining the internal transcribed spacer (ITS) region from all of the isolates of the pathogen identified as Rhizoctonia solani based on morphological characteristics (1). Fragments amplified using primers ITS1 (5'TCCGTAGGTGAACCTGCGG3') and ITS4 (5'TCCTCCGCTTATTGATATGC3') (4) were sequenced and compared with R. solani anastomosis group (AG) sequences available in the NCBI GenBank database. Sequence comparison identified this new isolate as R. solani anastomosis group AG 2-1. Previous isolates of target spot were identified as AG 3 (2). The isolates that were studied were deposited in the "Laboratorio de Sanidad Vegetal" INTA-EEA-Salta Microbial Collection as Rs59c, Rs59b, Rs59, Rs66, Rs67, Rs68, Rs69, and Rs70. The ITS nucleotide sequence of isolate Rs59 has been assigned the GenBank Accession No. JF792354. Pathogenicity tests for each isolate were performed using tobacco plants grown for 8 weeks at 25 ± 2°C with a 12-h photoperiod. Ten plants were inoculated by depositing PDA plugs (0.2 cm) colonized with R. solani onto leaves; plants inoculated with the pure PDA plug without pathogen served as controls. The plants were placed in a 25 ± 2°C growth chamber and misted and covered with polyethylene bags that were removed after 2 days when plants were moved to a glasshouse. After 48 h, symptoms began as small (1 to 2 mm), circular, water-soaked spots, lesions enlarged rapidly, and often developed a pattern of concentric rings of 1 to 2 cm. After 8 days, all inoculated plants showed typical disease symptoms. Morphological characteristics of the pathogen reisolated from symptomatic plants were consistent with R. solani. Control plants remained healthy. These results correspond to the first reports of the disease in the country. Compared to other areas in the world, target spot symptoms were only observed in tobacco plants produced in float systems and were not observed in the field. The prevalence of the disease in Salta, Argentina was 7%. To our knowledge, this is the first report of R. solani AG2.1 causing target spot of tobacco. References: (1) M. Sharon et al.

Abstract
INTRODUCTION The Global Database on Donation and Transplantation is one of the main areas of the Global Observatory on Donation and Transplantation (GODT), which is the information platform designed to implement some of the requirements of the World Health Assembly Resolution WHA57.18. OBJECTIVES OF THE GLOBAL DATABASE: The objectives are to collect, analyze, and disseminate information on legislative and organizational frameworks and annual aggregated data on donation and transplantation activities of the World Health Organization (WHO) Member States. Another objective is to establish the transplantation network with the national health authorities. The database should provide a working tool that helps to exchange information and be a reference for professionals involved, promoting international cooperation through the website. METHODS The data collection for the Global Database is done through a specific questionnaire, including questions on legislation, organizational systems, and updated data on organs, tissues and cells donation, and transplantation from each country. For the statistical analysis of activity data, descriptive statistics have been used. RESULTS The Global Database has organizational and legislative pieces of information of 94 countries. In 2007 activity data of 97 countries have been analyzed. Reported to the database were 21,489 deceased donors. Currently around 100,000 solid organ transplantations are performed per year worldwide: 68,250 kidney, 19,850 liver, 5179 heart, 3245 lung, and 2797 pancreas transplantations. CONCLUSIONS This kind of tool is necessary to improve knowledge about the donation and transplantation activities over the world. Close collaboration with countries is crucial to obtain reliable data.

Abstract
The aroma of saffron has received much attention from scientists in recent years, not only for the compounds that make it up, but also for its glycosidic precursors. Despite it all, the volatile generation mechanisms of the spice are almost completely unknown. Only the generation of safranal, the major compound, from picrocrocin has been established. The great effort carried out to detect and identify the volatile compounds of saffron has not been enough to clarify which compounds are responsible for saffron aroma. In general, scientists has devoted little attention to the sample analyzed, taking for granted that all saffron is the same, something that makes it difficult to establish a comparison between the results obtained by the different authors, to the point that saffron aroma has not been defined yet. It must be clarified whether saffron aroma is what the consumer perceives via nasally when a container of the spice is uncovered, or whether on the contrary, it is the aroma conferred to food, normally after a thermal cooking process, and perceived retronasally. After an extensive bibliographic research, simple assays are suggested to understand what could be considered as saffron aroma, results that may help to delimit the research for future studies.

Abstract
BACKGROUND There is a lack of information on health expenses caused by readmissions among hematopoietic stem cell transplant (HSCT) recipients. We analyzed the rate, causes, and evolution of hospitalization after HSCT. METHODS We retrospectively studied 140 consecutive patients who received an autologous HSCT (n = 107; 76.4%) or an allogeneic HSCT (n = 33; 23.6%) in our institution from May 2001 through September 2004. RESULTS There were 45 readmissions in 28 patients (20%): three (10%) in the autologous and 25 (90%), in the allogeneic HSCT cohorts. The overall median age was 35.3 +/- 13.5 years and 54% were women. Hematologic diseases were: multiple myeloma (n = 1, 4%), myelodysplastic syndrome (n = 2, 7%), acute lymphoblastic leukemia (n = 2, 7%), aplastic anemia (n = 2, 7%), chronic myeloid leukemia (n = 3, 11%), non-Hodgkin's lymphoma (n = 4, 14%), Hodgkin's disease (n = 4, 14%) and acute nonlymphoblastic leukemia (n = 10, 38%). The length of stay for each readmission was 25 +/- 21 days. The median day of readmission was +62.5 (range = +19 to +987); however, 75% occurred between days +30 and +70. The causes of hospitalization were: infections (n = 24, 54%), due to the graft (n = 14, 31%), graft failure (n = 4, 9%), coagulation disorders (n = 2, 4%), and second neoplasm (n = 1, 2%). Mortality due to the transplant was 10 patients (14%) including: graft-versus-host disease (n = 3), sepsis (n = 3), thrombotic thrombocytopenic purpura (n = 1), and relapse (n = 3). CONCLUSIONS Although there was a frequent use of hospital resources (20%) after HSCT with patients hospitalized for a median of 25 days, it was beneficial since there were 86% survivors at 36 months follow-up.

Abstract
In the yeast Xanthophyllomyces dendrorhous the genes idi, crtE, crtYB, crtl and ast are involved in the biosynthesis of astaxanthin from isopentenyl pyrophosphate. The carotenoid production and the kinetics of mRNA expression of structural genes controlling the carotenogenesis in a wild-type ATCC 24230 and in carotenoid overproducer deregulated atxS2 strains were studied. The biosynthesis of carotenoid was induced at the late exponential growth phase in both strains. However, the cellular carotenoid concentration was four times higher in atxS2 than in the wild-type strain in the exponential growth phase, suggesting that carotenogenesis was deregulated in atxS2 at the beginning of growth. In addition, the maximum expression of the carotenogenesis genes at the mRNA level was observed during the induction period of carotenoid biosynthesis in the wild-type strain. The mRNA level of the crtYB, crtl, ast genes and to a lesser extent the idi gene, decayed at the end of the exponential growth phase. The mRNA levels of the crtE gene remained high along the whole growth curve of the yeast. In the atxS2 strain the mRNA levels of crtE gene were about two times higher than the wild-type strain in the early phase of the growth cycle.

Abstract
Abnormal tau phosphorylation and deposition in neurones and glial cells is one of the major features in taupathies. The present study examines the involvement of the Ras/MEK/ERK pathway of tau phosphorylation in Alzheimer disease (AD), Pick's disease (PiD), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD), by Western blotting, single and double-labelling immunohistochemistry, and p21Ras activation assay. Since this pathway is also activated in several paradigms of cell death and cell survival, activated ERK expression is also analysed with double-labelling immunohistochemistry and in situ end-labelling of nuclear DNA fragmentation to visualise activated ERK in cells with increased nuclear DNA vulnerability. The MEK1 antibody recognises one band of 45 kD that identifies phosphorylation-independent MEK1, whose expression levels are not modified in diseased brains. The ERK antibody recognises one band of 42 kD corresponding to the molecular weight of phosphorylation-independent ERK2; the expression levels, as well as the immunoreactivity of ERK in individual cells, is not changed in AD, PiD, PSP and CBD. The antibody MAPK-P distinguishes two bands of 44 kD and 42 kD that detect phosphorylated ERK1 and ERK2. MAPK-P expression levels, as seen with Western blotting, are markedly increased in AD, PiD, PSP and CBD. Moreover, immunohistochemistry discloses granular precipitates in the cytoplasm of neurones in AD, mainly in a subpopulation of neurones exhibiting early tau deposition, whereas neurones with developed neurofibrillary tangles are less commonly immunostained. MAPK-P also decorates neurones with Pick bodies in PiD, early tau deposition in neurones in PSP and CBD, and cortical achromatic neurones in CBD. In addition, strong MAPK-P immunoreactivity is found in large numbers of tau-positive glial cells in PSP and CBD, as seen with double-labelling immunohistochemistry. Yet no co-localisation of enhanced phosphorylated ERK immunoreactivity and nuclear DNA fragmentation is found in AD, PiD, PSP and CBD. Finally, activated Ras expression levels are increased in AD cases when compared with controls. These results demonstrate increased phosphorylated (active) ERK expression in association with early tau deposition in neurones and glial cells in taupathies, and suggest activated Ras as the upstream activator of the MEK/ERK pathway of tau phosphorylation in AD.

Abstract
Tau phosphorylation was examined in argyrophilic grain disease (AGD) by using the phosphospecific tau antibodies Thr181, Ser202, Ser214, Ser 396 and Ser422, and antibodies to non-phosphorylated and phosphorylated mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases (ERK), stress-activated kinase (SAPK), c-Jun N-terminal kinase (JNK), p38 kinase (p-38), alpha-calcium/calmodulin-dependent kinase II (alphaCaM kinase II), and glycogen synthase kinase-3 (GSK-3), all of which regulate phosphorylation at specific sites of tau. This is the first study in which the role of protein kinases in tau phosphorylation has been examined in AGD. Hyperphosphorylated tau accumulated in grains and pre-tangles in the hippocampus, dentate gyrus, entorhinal and trans-entorhinal cortices, and amygdala in all cases. Ballooned neurons in the amygdala, entorhinal, insular and cingulate cortex, and claustrum contained alphaB-crystallyn and phosphorylated neurofilament epitopes. Some astrocytes and scattered oligodendrocytes containing coiled bodies were recognized with anti-tau antibodies. A few tangles were observed in the entorhinal cortex and hippocampus corresponding to Alzheimer's disease (AD) stages I-III of Braak and Braak. None of the present cases was associated with progressive supranuclear palsy or with alpha-synuclein pathology. Two bands of phospho-tau of 64 and 68 kDa were observed in Western blots of sarkosyl-insoluble fractions enriched with abnormal filaments in AGD, a pattern that contrasts with the 4-band pattern obtained in AD. No modifications in the expression of non-phosphorylated MEK-1, ERK2 and GSK-3alpha/beta, as revealed by immunohistochemistry, were seen in AGD, but sarkosyl-insoluble fractions were particularly enriched in JNK-1 and alphaCaM kinase II. Increased expression of the phosphorylated (P) forms of MAPK/ERK, SAPK/JNK, p38 and GSK-3beta was found in grains and tau-containing cells in AGD. MAPK/ERK-P immunoreactivity was observed in pre-tangles and, diffusely, in the cytoplasm of ballooned neurons, but not in grains. Strong SAPK/JNK-P and P38-P, and moderate GSK-3b-P immunoreactivities selectively occured in grains, in neurons with pre-tangles and in the peripheral region of the cytoplasm of ballooned neurons. MAPK/ERK-P, SAPK/JNK-P, p38-P and GSK-3beta-P were expressed in tau-containing astrocytes and in oligodendrocytes with coiled bodies. Western blots revealed kinase expression in sarkosyl-insoluble fractions but none of the phospho-kinase antibodies recognized hyper-phosphorylated tau protein. These findings indicate complex, specific profiles of tau phosphorylation and concomitant activation of precise kinases that have the capacity to phosphorylate tau at specific sites in AGD. These kinases co-localize abnormal tau in selected structures and cells, including neurons with pre-tangles, ballooned neurons, astrocytes and oligodendrocytes. Most of these kinases are involved in cell death and cell survival in certain experimental paradigms. However, double-labeling studies with the method of in situ end-labeling of nuclear DNA fragmentation and cleaved (active) caspase-3 immunohistochemistry show no expression of apoptosis and death markers in cells bearing phosphorylated kinases.

Abstract
The degradation of p-Coumaric acid present in olive oil mill wastewater was investigated as a pretreatment stage to obtain more easily biodegradable molecules, with lower toxicity that facilitates subsequent anaerobic digestion. Thus, photo-Fenton-assisted ozonation has been studied and compared with ozonation at alkaline pH and conventional single ultraviolet (UV) and acid ozonation treatments. In the combined process, the overall kinetic rate constant was split into various components: direct oxidation by UV light, direct oxidation by ozone and oxidation by hydroxyl radicals. Molecular and/or radical ozone reaction was studied by conducting the reaction in the presence and absence of tert-butylalcohol at pHs 2, 7 and 9. Ozone oxidation rate increases with pH or by the addition of Fenton reagent and/or UV radiation due to generation of hydroxyl radicals, *OH. Hydrogen peroxide and ferrous ion play a double role during oxidation since at low concentrations they act as initiators of hydroxyl radicals but at high concentrations they act as radical scavengers. Finally, the additional levels of degradation by formation of hydroxyl radicals have been quantified in comparison to the conventional single processes and an equation is proposed for the reaction rate as a function of studied operating variables.

Abstract
A screening method for the detection of artificial colours (naphthol yellow, tartrazine, quinoline yellow, Sunset yellow, Allura red, amaranth, azorubine, Ponceau 4R and Red 2G) in saffron is described. The method involves removal of crocins by precipitation of crocetin (pH 0.1, 90 degrees C) before adsorption of the artificial colours on polyamide SPE cartridges (pH 2). After washing with methanol, acetone and methanol, elution was done with a methanol:ammonia solution (95:5 v/v), and detection was performed by derivative spectrometry. Sample pretreatment changes the UV-Vis saffron extract profile in such a way that second derivative spectra can be used to identify the presence of added colours. Erythrosine, which was found to be pH dependent, could not be detected under the above conditions. The lowest detectable amount for each colour was strongly dependent on chemical structure. The recovery of carminic acid was very low possibly due to irreversible retention on the polyamide. This procedure can replace the current ISO TLC method (2003) and be used alternatively or in combination with HPLC procedures adopted in the same standard.

Abstract
Myofibrillar myopathies (MM) are characterized morphologically by the presence of non-hyaline structures corresponding to foci of dissolution of myofibrils, and hyaline lesions composed of aggregates of compacted and degraded myofibrillar elements. Inclusion body myositis (IBM) is characterized by the presence of rimmed vacuoles, eosinophilic inclusions in the cytoplasm, rare intranuclear inclusions, and by the accumulation of several abnormal proteins. Recent studies have demonstrated impaired proteasomal expression and activity in MM and IBM, thus accounting, in part, for the abnormal protein accumulation in these diseases. The present study examines other factors involved in protein aggregation in MM and IBM. Clusterin is a multiple-function protein which participates in Abeta-amyloid, PrP(res) and a-synuclein aggregation in Alzheimer disease, prionopathies and a-synucleinopathies, respectively. gamma-Tubulin is present in the centrosome and is an intracellular marker of the aggresome. Moderate or strong clusterin immunoreactivity has been found in association with abnormal protein deposits, as revealed by immunohistochemistry, single and double-labeling immunofluorescence and confocal microscopy, in MM and IBM, and in target structures in denervation atrophy. Gamma-Tubulin has also been observed in association with abnormal protein deposits in MM, IBM, and in target fibers in denervation atrophy. These morphological findings are accompanied by increased expression of clusterin and gamma-tubulin in muscle homogenates of MM and IBM cases, as revealed by gel electrophoresis and Western blots. Together, these observations demonstrate involvement of clusterin in protein aggregates, and increased expression of aggresome markers in association with abnormal protein inclusions in MM and IBM and in targets, as crucial events related to the pathogenesis of abnormal protein accumulation and degradation in these muscular diseases.

Abstract
Stem cell transplantation (SCT) is an effective treatment for life-threatening hematologic and nonhematologic pediatric diseases. Reducing transplant-related mortality (TRM), a major complication of SCT, to improve long-term survival, therefore, is one of the main objectives of transplantation teams. We analyzed TRM and overall survival (OS) over the years in children undergoing SCT in our center. From June 1998 to October 2002, 156 consecutive children, 105 boys and 51 girls, median age 10 years (range, 2-18), with different diagnoses underwent SCT (100 autologous and 56 allogeneic). OS and TRM were analyzed in 2 different periods (June 1989-December 1998 and January 1999-October 2002) and grouped according to the different SCT modalities. The median follow-up was 18 months (range, 1-160). Autologous TRM showed a statistically significant improvement within 1999-2002 (0%) compared with 1989-1998 (12.2%) (P < .05). There were no statistical differences for allogeneic SCT. OS was 34% in the first period and 80.4% in the second period (P < .01), the improvement being for both autologous and allogeneic SCT. In our study, TRM decreased significantly for those children receiving autologous SCT in recent years. OS was significantly better in the latter period (1999-2002), both globally and for each SCT modality.

Abstract
Modelling of soot and SOF emissions from a typical European turbocharged diesel engine has been made. The model consists of a detailed kinetic mechanism with 472 reactions (120 chemical species) and data from the thermodynamic diagnostic procedure of the combustion process of the engine. The forward kinetic constants were obtained from literature and the background constants from a self-developed non-linear fitting routine based on the Marquardt algorithm. The dilution and mixing processes inside the engine are represented by a simple Wiebe function. The system of ordinary differential equations is solved with the Rosenbrock method for rigid systems and using the interpolating Lagrange polynomials to calculate the heat capacity of each species at the corresponding temperature. The kinetic model has been implemented in Digital Visual Fortran 6.0. The model has been executed for five different fuels and three mixtures of biodiesel and reference diesel operating under three diverse conditions from the European transient urban/extraurban Certification Cycle and the results of soot and SOF predicted are compared with experimental data.

Abstract
Doppel (Dpl) is a prion-like protein encoded by the gene PRND, which has been found downstream of the prion gene PRNP in several species. The present study examines by immunohistochemistry Dpl expression in brain samples from 10 patients with Alzheimer's disease (AD), three patients with Pick's disease, four patients with Parkinson's disease, eight patients with diffuse Lewy body disease (DLBD), six patients with sporadic Creutzfeldt-Jakob disease (CJD) methionine/methionine at the codon 129, two patients with sporadic CJD methionine/valine at the codon 129 and numerous kuru plaques in the cerebellum, one patient with fatal familial insomnia (FFI), and 10 age-matched controls. In the adult human brain, Dpl immunoreactivity was restricted to scattered granule cells of the cerebellum and scattered small granules in the cerebral cortex. Dpl immunoreactivity was seen around betaA4 amyloid deposits in neuritic plaques, but not in diffuse plaques, AD and the common form of DLBD. Neurofibrillary tangles, Pick bodies and Lewy bodies were not stained with anti-Dpl antibodies. No modifications in Dpl immunoreactivity were observed in CJD excepting those associated with accompanying senile plaques. No Dpl-positive deposits were seen in FFI. Whether Dpl in neuritic plaques may attenuate amyloid-induced oxidative stress and participate in the glial response around amyloid cores is discussed in light of the few available data on Dpl functions.

Abstract
NO(x), nitrate and sulphate emissions from a typical European passenger car diesel engine have been measured testing eight different fuels under five steady operating conditions (reproducing modes of the European transient urban/extraurban certification cycle). It is confirmed that nitrogen species compete with sulphur compounds to be adsorbed by diesel particulate matter (DPM) before being emitted into the atmosphere. This competition is found to increase with engine load, and is explained on the basis of the different specific surface and adsorption capacity of soot particles under different operating modes. When a high specific surface is available, as occurs in low load modes, both nitrates and sulphates are adsorbed by soot particles. On the contrary when a small surface is accessible, like in high load modes, sulphates are selectively adsorbed. This is specially important since sulphates are responsible for hydrocarbon retention in DPM due to the scrubbing effect.
