＂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.

We previously showed that the increase in nitric oxide (NO) levels and NO synthase (NOS) expression correlate with the progression of reactive astrocytosis and demyelination in the brains of 6-month-old taiep rats. Increased levels of NO can result in high concentration of peroxynitrite and thus cause tissue damage, which consists of lipoperoxidation of the cytoplasmic membrane, such as the myelin, and of apoptotic and necrotic cell-death. On this basis, we studied whether the increased NO production is associated with lipoperoxidation and cell death in the cerebellum and brainstem over the age (1, 3, 6, and 8 months) of taiep rats. The results were compared with those obtained in matched Sprague-Dawley (SD) rats. We measured the levels of nitrites (NO production), malonyldialdehyde, and 4-hydroxyalkenal (lipoperoxidation) in brain tissue homogenates. The three NOS isoforms and cleaved caspase-3 were evaluated by using ELISA and immunostaining techniques. Our results showed that NO production and lipoperoxidation increased in the cerebellum and brainstem as the age of the taiep rats increased compared to SD rats. The overexpression of nNOS and iNOS were in the Purkinje cells, magnocellular neurons, and in oligodendrocytes, whereas the glial cells showed strong cleaved-caspase-3 immunoreactivity. In summary our results suggest that NO plays a role in the demyelination and cell death in the taiep rat.

Extensins （EXTs） are highly repetitive plant O-glycoproteins that require several post-translational modifi- cations （PTms） to become functional in plant cell walls. First, they are hydroxylated on contiguous proline residues; then they are O-glycosylated on hydroxyproline and serine. After secretion into the apoplast, O-glycosylated EXTs form a tridimensional network organized by inter- and intra-Tyr linkages. Recent studies have made significant progress in the identification of the enzymatic machinery required to process EXTs, which includes prolyl 4-hydroxylases, glycosyltransferases, papain-type cysteine endopeptidases, and peroxidases. EXTs are abundant in plant tissues and are particularly important in rapidly expanding root hairs and pollen tubes, which grow in a polar manner. Small changes in EXT PTms affect fastgrowing cells, although the molecular mechanisms underlying this regulation are unknown. In this review, we highlight recent advances in our understanding of EXT modifications throughout the secretory pathway, EXT assembly in cell walls, and possible sensing mechanisms involving the Catharanthus roseus cell surface sensor receptor-like kinases located at the interface between the apoplast and the cytoplasmic side of the plasma membrane.

This is a report of the validation process of two scales that measure the OIS-Garcia (optimist interactive style). An attempt was made to establish construct and convergent validity for these two scales. Towards this end, we relied on the Spanish version of the LOT-R (life orientation test-revised). Participants were 350 relatives of a cancer patient with a mean age of 39.87 years (SD = 14.88) and an age range going from 15 to 79 years. Each of the new versions of the OIS1-Garcia and OIS2-Garcia comprised 10 items. The Chronbach alpha internal consistency coefficients were 0.701 for the OIS1 and 0.633 for the OIS2. The Spearman correlation coefficient among these two tests was 0.438, the correlation among LOT-R and OIS1-Garcia was 0.382, and the correlation among LOT-R and OIS2-Garcia was 0.468. As a result, we were able to partially validate both versions of the OIS-Garcia test. These findings serve as encouragement to develop more culturally sensitive and appropriate measurement instruments for specific cultures or populations.
