Plant peroxisomes have the capacity to gen erate different reactive oxygen and nitrogen species(ROS and RNS),such as H2O2,superoxide radical(O2^·-),nitric oxide and peroxynitrite(ONOO^-).These organelles have an active nitrooxidative metabolism which can be exacerbated by adverse stress *** sulfide(H2S)is a new signaling gasotransmitter which can mediate the posttranslational modification(PTM)*** used Arabidopsis thaliana transgenic seedlings expressing cyan fluorescent protein(CFP)fused to a canonical peroxisome targeting signal 1(PTS1)to visualize peroxisomes in living cells,as well as a specific fluorescent probe which showed that peroxisomes contain H2S.H2S was also detected in chloroplasts under glyphosate-induced oxidative stress *** enzyme activities,including catalase,photorespiratory H2O2-generating glycolate oxidase(GOX)and hydroxypyruvate reductase(HPR),were assayed in vitro with a H2S *** line with the persulfidation of this enzyme,catalase activity declined significantly in the presence of the H2S *** corroborate the inhibitory effect of H2S on catalase activity,we also assayed pure catalase from bovine liver and pepper fruit-enriched samples,in which catalase activity was *** together,these data provide evidenee of the presence of H2S in plant peroxisomes which appears to regulate catalase activity and,consequently,the peroxisomal H2O2 metabolism.

Background: Influenza A (H1N1) is the most recent pandemic disease that has affected the human population. Objective: To evaluate knowledge and preventive measures related with this disease one year after the epidemic of Mexico- that took place in 2009. Material and methods: An epidemiologic survey regarding influenza A (H1N1) was conducted in June 2010 among 2541 students from the second grade of all public high schools in a borough in Mexico City. The questionnaire included items on the knowledge of the disease and practice of preventive measures. Results: Most students obtained the information from television, half of them from parents and only one fifth from teachers;72% of the participants had a favorable knowledge about the disease and the measures to avoid being infected. However, only 37% practiced such preventive measures. Conclusion: Knowledge has a positive influence on practices towards health. Parents and teachers have an important role in health education, thus efforts should be directed to involve them more intensely in health education.

Dental plaque in adult patients is well identified as a reservoir for Helicobacter pylori. This question still remains unclear in children. The aim of this study is to identify the presence of this bacterium in dental plaque of Mexican pediatric patients, using Real Time Polymerase Chain Reaction (qPCR). Forty patients from 2 to 11 years without dyspeptic symptoms were enrolled. Samples were collected from the subgingival space of the lingual side of the lower molars and cultured in selective medium. Therefore, qPCR analysis was conducted. According to the results obtained in this study, it was found that 35% of the pediatric population who participated tested qPCR positive for the presence of H. pylori in dental plaque samples. No significant associations were detected among isolation rate by gender or age. We found that dental plaque may be a reservoir for H. pylori. However, more research is needed to establish the way of the infection of pediatric population.

In the Mexican tropics the guava trees can grow and produce in any season, so they can be har-vested out of the period of high competition marketing (Summer). It?studied the growth kinetics of leaves and fruits of guava trees at the dry tropical conditions of the State of Guerrero, in guava trees of four years old and was evaluated a non-destructive method for measuring leaf area from November to May. 100 sheets of 10 randomly selected trees were cut. It was found that leaf length X the width X 0.72581647 (conversion factor) gave an estimated leaf area which?was significantly correlated with that obtained by the integrator of leaf area. Both in length and width the leaf growth kinetics were sigmoid with three growth stages: In Stage I (15 days) leaves grew 21.2% and 21.5%;in Stage II (26 days) grew 73.6% and 68%;and in Stage III (30 days). They Increased 5.2% and 10.5% in the primary and secondary sprouts. The fruit growth in its equatorial and polar diameters corresponded to a double sigmoid kinetics. In Stage I (61 days) it reached 1.9 and 2.3 cm;in Stage II (62 - 102 days) it reached 3.09 and 3.62 cm;and in Stage III (103 to 126 days) it reached 4.63 and 5.13 cm, as well the physiological maturity of fruit.

＂Avocado sadness＂ caused by the Oomycete Phytophthora cinnamomi Rands, is one of the main diseases affecting this fruit crop in Michoacan, M6xico, without having an efficient control strategy for that. In this research three Trichoderma isolates and Ridomil Gold 4E fungicide were tested in avocado trees infected with this pathogen using the growing and coloring vegetative flow growing. Results were analyzed with an experimental design completely random with four treatments and repetitions. Different responses were presented form avocado trees to each treatment. Trichoderma erinaceum Bissett, Kubicek ＆ Szackacs treatment was the best controlling disease in trees with grade II and III damage. Trichoderma aggressivum Samuels ＆ W. Gams controlled better in trees with grade III damage. At last, Trichoderma arundinaceum Zafari, Graef. and Samuels were the best controlling trees with the highest grade damage. Fungicide Ridomil Gold 4E controlled the disease in trees with the lowest grade damage （I and II）, their medias were similar to witness.
