| The molecular characterization of ten genotypes of the Coffea arabica plants and of seven genotypes of C. canephora having interesting features for coffee breeding programs was carried to select the parents for breeding. A total of 40 SSR and 29 ISSR primers were used. The primers generated a total of 331 (307 polymorphic and 24 monomorphic) bands. Analysis of genetic diversity presented dissimilarity intervals ranging from 0.22 to 0.44 between the Conilon genotypes, from 0.02 to 0.28 between the Arabica genotypes, and from 0.49 to 0.60 between the genotypes of the two species in the joint analysis. Four groups were formed: I = genotypes of C. arabica, II = four progenies of C. canephora, Conilon group, and one non defined C. canephora (Conilon or... |

| This study aimed to evaluate the effect of corn silage (CS) replacement by cassava's foliage silage (CFS) on the production and quality of milk. Twelve lactating dairy cows were used in a randomized block experimental design with four treatments and three repetitions per block. CS was replaced by CFS at the levels of 0, 20, 40, and 60%. The replacement of CS by different levels of CFS had very low effect on the variables studied. Milk density decreased when the replacement level was increased. Fatty acids 4:0 and 6:0 presented a quadratic behavior, while fat acids 8:0, 10:0, and 15:0 presented a linear behavior as their concentrations fell when CFS diet content was increased. The CS replacement by 20% until 60% CFS resulted a significant decrease in the... |

| The aim of this study was to identify plants of the IAPAR-59 and Tupi IAC 1669-33 coffee cultivars with less defeated resistance genes by the rust races present at IAPAR (Londrina, Paraná State, Brazil) using test-crosses. Eighteen test-crosses derived from hybridizations between 'IAPAR-59' or 'Tupi IAC 1669-33' with susceptible coffee to the rust disease were evaluated. Six hybrids were used as susceptible standards originated from hybridizations between two susceptible coffee plants. Many parental plants of the 'IAPAR-59' and 'Tupi IAC 1669-33' presented more defeated resistance genes against rust races present at IAPAR than others of these cultivars or the genes were in heterozygous, because of segregant susceptible plants observed in some test-crosses.... |

| Powdered tomato was produced by spray drying the tomato pulp. A full 2³ factorial design with the central point was used, varying the feed flow rate (127-276 g/min), air inlet temperature (200-220ºC) and the atomisation speed (25,000-35,000 rpm). The responses analysed were: moisture content, solubility, wettability consistency and colour, but the factors only significantly affected the colour parameter. All the samples became significantly darker and less red with an increase of the variables under study. A low atomisation speed (25,000 rpm) and lower inlet air temperature (220ºC) produced the powders with a higher colour index (a/b) and less darkening. |

| This work presents bibliographic data on the role and function of microbial diversity. The increasing use of probiotics and prebiotics foods has led to the studies on their actual functions in the human body. It is known that in the environment, microorganisms are extremely important in recycling of nutrients, balance of trophic chains, vital physiological activities in the plants and animals, as well as the conservation of natural habitats. In human food, these microscopic organisms contribute from flavoring products to the synthesis of antimicrobial substances and vitamins essential to living beings. |

| To determine the indices of prevalence of intestinal parasites and commensals in the residents of ecotourism region of Paraná State, a retrospective study was conducte, from January/2003 to December/2004 on 3,764 fecal parasitological examinations performed by a private laboratory of Ubiratã using the Baermann-Moraes, water-sedimentation and Willis methods. Among the individuals aged eight months to 89 years, 522 (13.9%) cases were positive. Giardia lamblia (175/522; 24.2%) was the most prevalent parasite (p<0.000). Entamoeba coli was the most common commensal, with 238/552 (32.9%) cases (p<0.000), being frequently associated with other species, either parasitic or commensal. The children of preschool age (2-6 years old) and school age (7-14 years)... |

| The tolerability of stevioside (2.75 mg/kg/day) obtained from leaves of Stevia rebaudiana (Bert) Bertoni (Compositae) was investigated in hyperlipidemic patients. For this purpose a placebo controlled double blind study was performed. The patients were randomized in two groups: the first group received capsules containing placebo and the second group received capsules containing stevioside (50 mg) during 90 days. All capsules were ingested twice daily, i.e., 2 capsules before lunch and 2 capsules before dinner. After the selection of the patients and each 30 days body mass index and laboratory tests (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, total cholesterol, high density lipoprotein, low density lipoprotein, very... |

| The author describes the first cases of spontaneous leishmaniasis in guinea-pigs, as verified for the first time, in Curitiba, at the Institute of Biology and Technological Research. Studying the inoculability of Paracoccidioide brasiliensis in guinea-pigs, he found animals which presented tumoral lesions in the ears and peritesticular skin. The examination of these tumors, mixed with a small drop of Giemsa's original solution, plus the exam of the rubbings of the same material, coloured by the May-Grunwald Giemsa after fixation by Heidenhein's solution and the histological exams of the cuts in the tumoral lesions revealed the presence of elements which possessed the same morphology and aspect of the LEISHMAN-DONOVANI corpuscles. In the meanwhile, a... |

| ABSTRACT Organophosphorous pesticides (OPs) posses a great potential of acute toxicity for exposed animals and men. To evaluate the toxic potential of the organophosphate diazinon on root meristematic cells of Allium cepa L., was created two groups: In group 1 (control group), was not given any chemical. In group 2 (diazinon-treatment group), different doses (10, 40, 80 and 160 ppm) and times periods (24, 48 and 72 h) were administered. After exposure, cell death, effective concentration (EC50), mitotic index, cellular /chromosome aberrations, DNA damage by comet assay and RAPD-PCR were assessed at exposure times. EC50 value of diazinon was detected approximately 80 ppm. Hyperchromasia, later segragation, micronucleus, pulverised nucleus, nuclear... |
