Measurement response of thermoluminescent dosimeter, TLD, used by workers or placed at positions where gamma radiation field could be in action affecting biological tissues, should be completely characterized, in order to achieve the radiation quantity with precision and confidence. Among the evaluations concerned to its characterization, the detector reproductibility is of fundamental importance, because detectors present inside the TLD will be used many times in routine. Reproductibility is studied by repeated exposure to the same radiation field. The minimum detection limit is another important characteristics of a TLD. In this work evaluations of reproductibility and minimum detection are presented, for dosimeters produced at IPEN. |

To investigate the exposure of the Newcastle disease virus (NDV), infectious bursal disease virus (IBDV) and avian poxvirus (APV) in Magellanic penguins found on the beaches in Southern regions of Brazil, the frequency of serum antibodies was estimated in 89 samples taken during 2005 and 2006. All the penguins were negative for the presence of antibodies against NDV by hemagglutination inhibition test and to APV by indirect ELISA. The reactivity was similar to the positives controls using ELISA kit for the IBDV made in the chickens in 50 samples. This reactivity also was demonstrated in 42 samples using agar gel immunodiffusion. No clinical signs related to IBDV infection were observed. The results indicated the absence of infection by NDV and APV but... |

The present research had as objective to study the effects of moisture and extrusion temperatures on the oxidative stability of oat fine (< 532 µm) milling products. The oat caryopsis were ground in a Brabender mill and separated in two fractions, coarse over 532 µm and fine less than 532 µm. The fine fraction, with higher amount of starch and low amount of crude protein, lipids and dietary fiber content when compared to oat coarse milling products was conditioned to moisture levels (15.5-25.5 %) and extruded in a simple one-screw Brabender laboratory extruder (C/D= 20:1). The conditions of extrusion were compression ratio 3:1, screw speed of 100 rpm, a die of 6 mm in diameter and temperatures between 77.6 and 162.4 ºC in the 2nd and 3rd zones while the... |

ABSTRACT The presence of geneticdiversity is of great importance in improving wheat traits and developing strategies for optimal conservation of germplasm. Genetic diversity was assessed among common wheat cultivars using RAPD (Random Amplified Polymorphic DNA) markers at the Center of Agriculture, Biochemistry and Biotechnology (CABB), University of Agriculture, Faisalabad. RAPD primers were used among 14 Pakistani wheat cultivars, to screen the progenies and for the identification of the genes of interest. The polymorphic information content (PIC), was measured as the percentage of polymorphic fragments for all primers. A total of 583 bands(84% polymorphic) in all 14 wheat cultivars was amplified and discriminated all the wheat genotypes. The number of... |

The aim of the present study was to investigate the in vivo anti-metastatic activity of the red pigments of red yolk eggs laid by the ducks dieting on Potamogeton cripus L on the mammary carcinoma (4T1). The pigments were extracted with petroleum ether and acetone (2:1, v/v). BALB/c mice were divided into three groups (n=6), fed with the extracts at 150 mg/kg body weight (BW)/day (DEYE-H) or at 50 mg/kg BW/day (DEYE-L) and identical buffer without the extract (control group). The extracts were administered for 34 days. The treatment significantly inhibited the growth of orthotopical 4T1 tumour (DEYE-H vs control, 1:2; DEYE-L vs control, 2:3) and reduced the metastasis of tumour in the lungs (DEYE-H vs control, 4:7; DEYE-L vs control, 5:7), without... |

Abstract The present study aims to evaluate the influence of extraction methods on the quality of bioactive compounds and antioxidant capacity in Pterodon emarginatusVogel (sucupira) oils. The oils were extracted from the sucupira seeds by Soxhlet and by the extraction system of Bligh & Dyer. The oils were analyzed as to fatty acid profile, tocopherols, phytosterols, carotenoids, total phenolics, and total antioxidant capacity. The extraction by Soxhlet showed better yield of total lipids and was more efficient to extract tocopherols, phytosterols, and carotenoids, besides presenting better antioxidant activity by DPPH•. However, this method showed insufficient capacity to extract the polar lipid components of the sample, as evidenced by the low... |

The purpose of this study was to determine the susceptibilities of food-borne Aeromonas to carbapenems, as well as to investigate the presence of a metallo carbapenemase-encoding gene, named cphA. Minimum Inhibitory Concentration (MIC) was determined following NCCLS standards. All the tested microorganisms were susceptible to imipenem, meropenem and biapenem. However, a strong inoculum size effect on carbapenem MICs was observed for most of the strains. Six strains, out of seven, showed the presence of metallo--beta-lactamases but cphA gene was detected in only two strains of A. veronii bv. sobria. |

ABSTRACT Corn husks are the major wastes of corn industries with meagre economic significance. The present study was planned for value addition of corn husk through extraction of xylan, followed by its enzymatic hydrolysis into xylooligosaccharides, a pentose based prebiotic. Compositional analysis of corn husks revealed neutral detergent fibre 68.87%, acid detergent fibre 31.48%, hemicelluloses 37.39%, cellulose 29.07% and crude protein 2.68%. Irrespective of the extraction conditions, sodium hydroxide was found to be more effective in maximizing the yield of xylan from corn husks than potassium hydroxide (84% vs. 66%). Application of xylanase over the xylan of corn husks resulted into production of xylooligosaccharides with different degree of... |

During the assessments carried out by the authors at the diverse laboratories pertaining to the network of accredited laboratories - known as the Brazilian Calibration Network (RBC) - the authors verified the difficulties that these laboratories had in meeting the requirements of NBR ISO/IEC 17025:2001 (Standard), related to the maintenance of documents in the electronic media. More and more laboratories are substituting traditional control with electronic document control, which allows for more agility in the recovery of information. These laboratories implement policies and procedures; however, they still feel insecure, in some way, as to how to meet all of these requirements, thereby giving rise to difficulties in the implementation of such. The aim of... |
