El microplancton presentó las mayores densidades seguido del nanoplancton. Protoperidinium obtusum, indicador de ACF estuvo costero desde Punta Falsa hasta San Juan; en Chicama, Pisco y entre Punta Mendieta-Punta Caballas se distribuyó hasta 40 mn. Ceratium praelongum, indicador de ASS presentó una distribución variada entre Paita y Matarani, alcanzó máximo acercamiento a la costa en Chala.

Treatment of acute uncomplicated falciparum malaria with artemether-lumefantrine in nonimmune populations: a safety, efficacy, and pharmacokinetic study.

The efficacy and safety of artemether-lumefantrine for the treatment of malaria in nonimmune populations are not well defined. In this study, 165 nonimmune patients from Europe and non-malarious areas of Colombia with acute, uncomplicated falciparum malaria or mixed infection including P. falciparum were treated with the six-dose regimen of artemether-lumefantrine. The parasitologic cure rate at 28 days was 96.0% for the per protocol population (119/124 patients). Median times to parasite clearance and fever clearance were 41.5 and 36.8 hours, respectively. No patient had gametocytes after Day 7. Treatment was well tolerated; most adverse events were mild to moderate and seemed to be related to malaria. There were few serious adverse events, none of which were considered to be drug-related. No significant effects on ECG or laboratory parameters were observed. In conclusion, the six-dose regimen of artemether-lumefantrine was effective and well tolerated in the treatment of acute uncomplicated falciparum malaria in nonimmune patients.

Evaluation of occupational exposure: comparison of biological and environmental variabilities using physiologically based toxicokinetic modeling

PURPOSE: Few studies compare the variabilities that characterize environmental (EM) and biological monitoring (BM) data. Indeed, comparing their respective variabilities can help to identify the best strategy for evaluating occupational exposure. The objective of this study is to quantify the biological variability associated with 18 bio-indicators currently used in work environments. METHOD: Intra-individual (BV(intra)), inter-individual (BV(inter)), and total biological variability (BV(total)) were quantified using validated physiologically based toxicokinetic (PBTK) models coupled with Monte Carlo simulations. Two environmental exposure profiles with different levels of variability were considered (GSD of 1.5 and 2.0). RESULTS: PBTK models coupled with Monte Carlo simulations were successfully used to predict the biological variability of biological exposure indicators. The predicted values follow a lognormal distribution, characterized by GSD ranging from 1.1 to 2.3. Our results show that there is a link between biological variability and the half-life of bio-indicators, since BV(intra) and BV(total) both decrease as the biological indicator half-lives increase. BV(intra) is always lower than the variability in the air concentrations. On an individual basis, this means that the variability associated with the measurement of biological indicators is always lower than the variability characterizing airborne levels of contaminants. For a group of workers, BM is less variable than EM for bio-indicators with half-lives longer than 10-15 h. CONCLUSION: The variability data obtained in the present study can be useful in the development of BM strategies for exposure assessment and can be used to calculate the number of samples required for guiding industrial hygienists or medical doctors in decision-making.

Prediction of 18-month survival in patients with primary myelodysplastic syndrome. A regression model and scoring system based on the combination of chromosome findings and the Bournemouth score.

The predictive potential of six selected factors was assessed in 72 patients with primary myelodysplastic syndrome using univariate and multivariate logistic regression analysis of survival at 18 months. Factors were age (above median of 69 years), dysplastic features in the three myeloid bone marrow cell lineages, presence of chromosome defects, all metaphases abnormal, double or complex chromosome defects (C23), and a Bournemouth score of 2, 3, or 4 (B234). In the multivariate approach, B234 and C23 proved to be significantly associated with a reduction in the survival probability. The similarity of the regression coefficients associated with these two factors means that they have about the same weight. Consequently, the model was simplified by counting the number of factors (0, 1, or 2) present in each patient, thus generating a scoring system called the Lausanne-Bournemouth score (LB score). The LB score combines the well-recognized and easy-to-use Bournemouth score (B score) with the chromosome defect complexity, C23 constituting an additional indicator of patient outcome. The predicted risk of death within 18 months calculated from the model is as follows: 7.1% (confidence interval: 1.7-24.8) for patients with an LB score of 0, 60.1% (44.7-73.8) for an LB score of 1, and 96.8% (84.5-99.4) for an LB score of 2. The scoring system presented here has several interesting features. The LB score may improve the predictive value of the B score, as it is able to recognize two prognostic groups in the intermediate risk category of patients with B scores of 2 or 3. It has also the ability to identify two distinct prognostic subclasses among RAEB and possibly CMML patients. In addition to its above-described usefulness in the prognostic evaluation, the LB score may bring new insights into the understanding of evolution patterns in MDS. We used the combination of the B score and chromosome complexity to define four classes which may be considered four possible states of myelodysplasia and which describe two distinct evolutional pathways.

Identification and removal of low-complexity sites in allele-specific analysis of ChIP-seq data.

MOTIVATION: High-throughput sequencing technologies enable the genome-wide analysis of the impact of genetic variation on molecular phenotypes at unprecedented resolution. However, although powerful, these technologies can also introduce unexpected artifacts. Results: We investigated the impact of library amplification bias on the identification of allele-specific (AS) molecular events from high-throughput sequencing data derived from chromatin immunoprecipitation assays (ChIP-seq). Putative AS DNA binding activity for RNA polymerase II was determined using ChIP-seq data derived from lymphoblastoid cell lines of two parent-daughter trios. We found that, at high-sequencing depth, many significant AS binding sites suffered from an amplification bias, as evidenced by a larger number of clonal reads representing one of the two alleles. To alleviate this bias, we devised an amplification bias detection strategy, which filters out sites with low read complexity and sites featuring a significant excess of clonal reads. This method will be useful for AS analyses involving ChIP-seq and other functional sequencing assays.

Mudanças da fertilidade do solo e crescimento de um povoamento de Eucalyptus grandis fertilizado com biossólido

Antes da recomendação em larga escala de biossólido em plantações florestais, é preciso compreender seus efeitos no solo e na planta. Assim, a fertilidade do solo, o estado nutricional e o crescimento de um povoamento de Eucalyptus grandis fertilizado com biossólido foram avaliados em um experimento na Estação Experimental de Ciências Florestais de Itatinga (SP), ESALQ/USP. O delineamento experimental foi o de blocos casualizados, com quatro blocos e nove tratamentos: (1) Testemunha; (2) Adubação mineral; (3) 5 t ha-1 de bios. + K; (4) 10 t ha-1 de bios. + K; (5) 10 t ha-1 de bios.; (6) 10 t ha-1 de bios. + K + P; (7) 15 t ha-1 de bios. + K; (8) 20 t ha-1 de bios. + K, e (9) 40 t ha-1 de bios. + K. Foram analisadas quimicamente amostras de solo (camadas de 0-5, 5-10 e 10-20 cm) e de folhas. A produção de madeira foi avaliada por meio da colheita e pesagem de árvores. Até 32 meses após a aplicação do biossólido, 36 meses pós-plantio, constataram-se aumentos do pH, dos teores de C orgânico, de P-resina e de Ca trocável nas três camadas, diretamente associados às doses de biossólido aplicadas. Os teores de S-SO4(2-) e K trocável diminuíram 13 meses após a aplicação do biossólido e, 19 meses depois, os teores estavam aumentados. O Al trocável diminuiu com o aumento das doses de biossólido, nas três camadas amostradas. A aplicação de biossólido influiu positivamente na nutrição das plantas, proporcionando uma produção de madeira igual à obtida no tratamento que só recebeu adubação mineral (1,5 t ha-1 de calcário dolomítico e, em kg ha-1, 98 de N, 79,5 de P2O5, 165 de K2O, 1,3 de B e 1,2 de Zn), quando a dose de biossólido foi equivalente a 12 t ha-1.
