Electrocoagulation of landfill leachate: Transforming a hazardous residue into a source of irrigation water.

Electrocoagulation of landfill leachate has been widely investigated, however, only few reports include the reuse of the treated water. In this work, treated leachate is evaluated as irrigation water. The main obstacle is the high Sodium Absorption Ratio (SAR=Na/(Ca+Mg)/2.

The Decline in HIV-1 Drug Resistance in Heavily Antiretroviral-Experienced Patients Is Associated with Optimized Prescriptions in a Treatment Roll-Out Program in Mexico.

A decrease in the rate of acquired antiretroviral (ARV) drug resistance (ADR) over time has been documented in high-income settings, but data on the determinants of this phenomenon are lacking. We tested the hypothesis that in heavily ARV-experienced patients in the Mexican ARV therapy (ART) roll-out program, the drop in ADR would be associated with changes in ARV drug usage. Genotypic resistance tests obtained from 974 HIV-infected patients with virological failure and at least 2 previously failed ARV regimens from throughout the country were analyzed for the presence of nucleos(t)ide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, and protease inhibitor (PI) resistance-associated mutations (RAMs).

A Hormonally Active Malignant Struma Ovarii.

Struma ovarii is a rare monodermal variant of ovarian teratoma that contains at least 50% thyroid tissue. Less than 8% of struma ovarii cases present with clinical and biochemical evidence of thyrotoxicosis due to ectopic production of thyroid hormone and only 5% undergo malignant transformation into a papillary thyroid carcinoma. Only isolated cases of hormonally active papillary thyroid carcinoma developing within a struma ovarii have been reported in the literature.

Words translated in sentence contexts produce repetition priming in visual word comprehension and spoken word production.

Previous research with words read in context at encoding showed little if any long-term repetition priming. In Experiment 1, 96 Spanish-English bilinguals translated words in isolation or in sentence contexts at encoding. At test, they translated words or named pictures corresponding to words produced at encoding and control words not previously presented.
