Tomato plants, Lycopersicon esculentum L. cv. Tmknvf 2 , and watermelon plants, Citrullus lanatus [Thomb.] Mansf. cv. Dulce maravilla, were grown for 30 days at different temperatures (15, 25 and 35°C). We analysed soluble phenolics, enzymatic activities (phenylalanine ammonia-lyase, polyphenol oxidase and peroxidase), and dry weight. The impact of the(More)
The understanding of the brain structure and function and its computational style is one of the biggest challenges both in Neuroscience and Neural Computation. In order to reach this and to test the predictions of neural network modeling, it is necessary to observe the activity of neural populations. In this paper we propose a hybrid modular computational(More)
The aim of the present work was to examine the relationship between proline metabolism and NAD kinase activity in greenbeans submitted to cold-shock. For this, 15-day-old greenbean plants were subjected to a temperature of 4 degrees C (cold shock) for 180 min. Our results indicate that the plants showed foliar accumulation of proline, with the enzymes(More)
The aim of this work was to analyse the dynamics of the nutritional state and biomass production in tobacco plants resulting from the application of various calcium levels (Ca1, 1.25 mol m À3 CaCl 2 ; Ca2, 2.50 mol m À3 CaCl 2 ; Ca3, 5 mol m À3 CaCl 2) in the culture medium. Tobacco plants were grown under controlled conditions and submitted to regular(More)
To understand the phytotoxic effects that certain bezimidazole fungicides exert on plant growth, the aim of the present study was to determine the effect of the fungicide carbendazim, on foliar biomass, pigment content, and nutrient levels in tobacco plants (Nicotiana tabacum L. cv. Tennessee 86). The fungicide applied was carbendazim with a purity of 100%,(More)
BACKGROUND Renal transplantation is the best treatment for end stage renal disease. Acute graft rejection is one of the main complications and may influence graft survival. OBJECTIVE To determine the incidence and features of acute cellular rejection (ACR) episodes confirmed by biopsy. METHODS We studied a cohort of 175 patients who underwent renal(More)
