RESUMO

Roughly 2 billion ha of land are degraded and in need of ecological restoration worldwide. Active restoration frequently involves revegetation, which leads to the dilemma of whether to conduct direct seeding or to plant nursery-grown seedlings. The choice of revegetation method can regulate plant survival and performance, with economic implications that ultimately feed back to our capacity to conduct restoration. We followed a peer-reviewed protocol to develop a systematic map that collates, describes and catalogues the available studies on how seeding compares to planting in achieving restoration targets. We compiled a database with the characteristics of all retrieved studies, which can be searched to identify studies of particular locations and habitats, objectives of restoration, plant material, technical aspects, and outcomes measured. The search was made in eight languages and retrieved 3355 publications, of which 178 were retained. The systematic map identifies research gaps, such as a lack of studies in the global South, in tropical rainforests, and covering a long time period, which represent opportunities to expand field-based research. Additionally, many studies overlooked reporting on important technical aspects such as seed provenance and nursery cultivation methods, and others such as watering or seedling protection were more frequently applied for planting than for seeding, which limits our capacity to learn from past research. Most studies measured outcomes related to the target plants but avoided measuring general restoration outcomes or economic aspects. This represents a relevant gap in research, as the choice of revegetation method is greatly based on economic aspects and the achievement of restoration goals goes beyond the establishment of plants. Finally, we identified a substantial volume of studies conducted in temperate regions and over short periods (0-5 y). This research cluster calls for a future in-depth synthesis, potentially through meta-analysis, to reveal the overall balance between seeding and planting and assess whether the response to this question is mediated by species traits, environmental characteristics, or technical aspects. Besides identifying research clusters and gaps, the systematic map database allows managers to find the most relevant scientific literature on the appropriateness of seeding vs. planting for particular conditions, such as certain species or habitats.

RESUMO

A systematic analysis of both tumors and the surrounding urothelium to help identify what lies behind the mechanism of multifocal tumor development has not yet been performed. In this study we investigated chromosome 1, 7, 9, and 17 aneusomy in 25 superficial papillary carcinomas and in 51 tissue samples taken from sites of macroscopically uninvolved urothelium surrounding the tumors, using the fluorescence in situ hybridization method. Our data demonstrated a close genetic relationship between all examined tumors and normal-appearing mucosa. Numeric aberrations of chromosomes 1, 7, 9, and 17 were found to exhibit similar patterns in all analyzed specimens, although with different frequencies.

RESUMO

Here we describe how we detected the BCR/ABL fusion gene on the short arm of der(9) combining classical GTG banding and Fluorescence In Situ Hybridization (FISH) in a case of chronic myeloid leukemia (CML). To our knowledge, variant translocations involving the short arm of chromosome 9, in literature, are almost rare in chronic myeloid leukemia. It is not clear if this complex genetic translocation represents clonal evolution or a unique, initial presentation variant of the Philadelphia chromosome (Ph).

RESUMO

The main focus of the present study was to assess the efficacy of interphase cytogenetics using fluorescence in situ hybridization (FISH) as a valid alternative to immunohistochemistry (IHC) in paraffin-embedded tissue sections and/or the efficacy of the combination of the two methods, while, at the same time, aiming to provide additional information on the use of the two methods. For this study, selected breast cancer patients (n=66) were tested for HER-2 gene amplification by FISH. The probe contains DNA sequences specific for the HER-2 human gene locus and hybridizes to the 17q11.2 through q12 region of human chromosome 17. The same samples were tested previously for HER-2 overexpression by two monoclonal antibodies (300G9 and CB11), recognizing an extracellular and an internal domain of gp185(Her-2), respectively. HER-2 overexpression also was evaluated using the HerceptTest Kit (Dako, Milan, Italy). The HerceptTest was performed according to the manufacturer's standard procedures, and results were scored on a 0 to 3+ scale. A total of 34 (51%) of 66 breast tumors enrolled in this study were positive by FISH. Of the 34 cases amplified by FISH, 9 were negative by IHC using both monoclonal antibody (MoAb) 300G9 and MoAb CB11, with a concordance rate from 80.3% to 83.3%. A higher concordance was verified (92.4%) when we used the HerceptTest Kit. Of the 32 cases found negative with the HerceptTest, FISH analysis identified HER-2 gene amplification in more than 10%. Our results indicate that with the combined use of both methods, several amplified samples classified negative by IHC can be used thus improving therapeutic planning for specific therapy with the monoclonal antibody trastuzumab.

RESUMO

BACKGROUND: Neutropenia is a common toxicity in patients receiving myelosuppressive chemotherapy. In this prospective pilot study, we compared the efficacy and safety profiles of pegfilgrastim administered subcutaneously once per cycle and lenograstim administered subcutaneously daily six times per cycle, for primary neutropenia prophylaxis in women with breast cancer receiving adjuvant anthracycline-based chemotherapy. MATERIALS AND METHODS: Twenty women were enrolled. All patients received epirubicin 100 mg/m(2) with 5-fluorouracil 500 mg/m(2) and cyclophosphamide 500 mg/m(2) on day 1 and every 21 days thereafter, according to the FEC 100 chemotherapy regimen. Eight patients received a single dose of pegfilgrastim on day 2, while 12 patients were treated with daily administration of lenograstim from days five to ten. Absolute neutrophil count and duration of grade 3-4 neutropenia were monitored using seriated blood samples. The incidence of bone pain was evaluated using the visual analog scale (VAS). RESULTS: The incidence of grade 3-4 neutropenia was 75% in patients who received pegfilgrastim, and 25% in patients who received lenograstim. One case of febrile neutropenia was shown in pegfilgrastim patients. The mean duration of grade 3-4 neutropenia was 2 days in pegfilgrastim group versus 1.4 days in the lenograstim group. Bone pain was present in 37.5% of pegfilgrastim patients versus 58.3% of lenograstim patients. The mean duration of bone pain in the pegfilgrastim group was 4 days versus 6 days in the lenograstim group. CONCLUSION: In our experience, a single injection of pegfilgrastim was less effective for controlling neutropenia than six daily injections of lenograstim. The safety profiles of pegfilgrastim and lenograstim were similar with a lower incidence of bone pain in patients treated with pegfilgrastim.
