Waste electrical and electronic equipment (WEEE) has brought negative effects to the environment produced by the materials that compose them. The proper implementation of management plans of WEEE should integrate measures to prevent, mitigate and correct these affectations. As an initial step, it is necessary to make a diagnosis of the current situation of WEEE management which is the objective of this work. The studied zone was composed by the municipalities of Tampico, Ciudad Madero and Altamira located in southeast Tamaulipas, Mexico. The descriptive analysis of technical and regulatory aspects of the current management system in the study area was developed, including generation rates and analysis of waste streams. Among the main results, the generation of WEEE was estimated in 2040.38 tons/year for 2013, distributed in the municipalities of Tampico with 830.93 tons/year, Altamira with 650.18 tons/year, and Ciudad Madero with 559.27 tons/year. This calculation was estimated using Mexico’s WEEE generation indicators. The analysis of waste streams includes five categories of WEEE, Televisions with 61% of the total generation, followed by sound devices with 18%, personal computers with 17%;mobile phones with 2% as well as fixed phones with 1%. In the study area, reports of Tampico’s municipality indicated that 96 tons of WEEE was collected in the city of Tampico in 2013. In México, the national legislation considers WEEE in the category of waste requiring special handling (WRSH), however, it exists an inadequacy in the environmental laws about the specific classification of this kind of debris that makes their effective management more difficult. No companies who provide a management or treatment operations for WEEE are reported in Tampico, or in the near region. In addition, despite an initial interest for the municipality to attend the WEEE problematic, it exists a lack of sensibility of the population in the absence of environmental education programs.

The objective of this work was to evaluate the effect of Beauveria bassiana(Bb 1205)on controlling Fusarium oxysporum ***(Fol 17108)in tomato plants in greenhouse *** of Bb 1205 was the most promising among the agronomic variables and expression of the activity of the enzymesβ-1,3-glucanases and *** of Bb 1205 occurred at a concentration of 1×108 conidia·mL−1,which was administered onto the leaves,directly into the soil and via *** with Fol 17108 occurred with 1×106 spores·mL−1,which were added directly to the *** was used for measuring agronomic parameters,namely activity of chitinases andβ-1,3-glucanases in foliage and *** Bb 1205 was added to the soil,the chlorophyll index and aerial part length showed significant *** addition,it was determined that root length,fresh weight of foliage,flower,and fruit count increased 82 days after inoculation(dai).Chitinase activity induced by Bb 1205 in leaves and roots of tomato plants infected with Fol 17108 was observed when injected into the stem at 32 dai(41.8 and 11.6-fold,respectively).Inoculation on the foliage showed a 10-fold increase ofβ-1,3-glucanases in the roots after 82 *** for leaves,a 3.8-fold increase was found when the stem was *** the different in vivo applications,Bb 1205 activated its defenses by expressing the chitinase enzymes andβ-1,3-glucanase,thus reducing the damage caused by Fol 17108,demonstrating increase plant growth thereafter.

AIM:To evaluate the impact of metadoxine(MTD) on the 3- and 6-mo survival of patients with severe alcoholic hepatitis(AH).METHODS:This study was an open-label clinical trial,performed at the"Hospital General de México,*** Liceaga".We randomized 135 patients who met the criteria for severe AH into the following groups:35 patients received prednisone(PDN)40 mg/d,35patients received PDN+MTD 500 mg three times daily,33 patients received pentoxifylline(PTX)400 mg three times daily,and 32 patients received PTX+MTD 500 mg three times *** duration of the treatment for all of the groups was 30 ***:In the groups treated with the MTD,thesurvival rate was higher at 3 mo(PTX+MTD 59.4%vs PTX 33.3%,P=0.04;PDN+MTD 68.6%vs PDN20%,P=0.0001)and at 6 mo(PTX+MTD 50%vs PTX18.2%,P=0.01;PDN+MTD 48.6%vs PDN 20%,P=0.003)than in the groups not treated with MTD.A relapse in alcohol intake was the primary independent factor predicting mortality at 6 *** patients receiving MTD maintained greater abstinence than those who did not receive it(74.5%vs 59.4%,P=0.02).CONCLUSION:MTD improves the 3-and 6-mo survival rates in patients with severe *** abstinence is a key factor for survival in these *** patients who received the combination therapy with MTD were more likely to maintain abstinence than those who received monotherapy with either PDN or PTX.

Background: This document includes recommendations and guidelines issued by a group of Mexican researchers and specialists gathered in the First National Colloquium for the Diagnosis and Management of Chronic Myeloid Leukaemia (CML) by initiative of Instituto Nacional de Cancerología and with the support of the Leukaemia Department of the MD Anderson Cancer Center. Mexico lacks of updated information taken from its own reality on the diagnosis and treatment of CML and other haematological disorders;besides, there are no national guidelines. Aim: To publish a consensus document with guidelines for the management of CML adjusted to the national environment and overall characteristics. Method: The participants answered a DELPHI questionnaire about the overall aspects of the disease, aiming to target controversial topics, discuss them in the colloquium, and to agree on the best ones. After those meetings, a final document was drawn up. Results: The group presents recommendations for definition, diagnosis, prognosis, monitoring, and treatment of CML in Mexico. Conclusions: Having consensus guidelines for the clinical management of CML in our country will enable the consensual practice of Mexican specialists regarding the clinical approach to CML, as well as optimize the resources which allow the rational planning of the medical care strategies.
