GANANCIA GENÉTICA ESPERADA EN MELINA ( Gmelina arborea Roxb.) EN CÓRDOBA (COLOMBIA)1

RESUMEN El Departamento de Córdoba (Colombia) planea plantar 200000 ha para el 2025 yGmelina arborea es una de las opciones dada su alta producción de biomasa en turnos cortos. El objetivo del estudio fue estimar el potencial de mejoramiento genético basado en la selección fenotípica de árboles plus en Córdoba y Magdalena. La selección se basó en la evaluación y comparación de cada árbol candidato con sus cuatro mejores vecinos en un radio de 20m, con base en su DAP, altura comercial, volumen comercial y, calidad del fuste basada en la calificación de sus primeras cuatro trozas de 2,5 m de largo. Los árboles plus se clasificaron como A cuando superaron tanto en volumen como en calidad a todos sus vecinos y, como B cuando solamente superaron en volumen o en calidad a sus vecinos. La ganancia genética se estimó para cada caracter mediante el producto de su diferencial de selección por un valor de heredabilidad esperable para G. arborea según literatura, tanto si se clonan (H2), como si se toma su semilla para plantar (h2). Se construyó un índice de selección que integró el volumen (60%) con la calidad (40%). De 57 árboles seleccionados, 35 fueron clasificados como plus A, que si se clonaran se estima se obtendrían ganancias genéticas de 5, 15, 36 y 34%, para el diámetro, altura comercial, volumen comercial y calidad del fuste, respectivamente. Los resultados sugieren un progreso genético importante con G. arborea en Córdoba, Colombia. Es necesario ampliar la base genética y comprobar estas estimaciones mediante ensayos genéticos.

Seletividade do nicosulfuron em três estádios fenológicos de milho-pipoca

Objetivou-se com este trabalho avaliar a seletividade do herbicida nicosulfuron em três estádios fenológicos de milho-pipoca (híbrido White A 448). O experimento foi conduzido em campo, seguindo o delineamento de blocos casualizados, com quatro repetições. Os tratamentos obedeceram a um esquema fatorial 5 x 3, referente a cinco dosagens de nicosulfuron (0; 17,5; 35; 70; e 140 g ha-1) e três estádios fenológicos (V3, V5 e V7), totalizando 15 tratamentos. A resposta do milho-pipoca ao nicosulfuron foi verificada por meio de avaliações visuais de intoxicação e efeitos sobre a altura das plantas aos 7, 14 e 28 dias após a aplicação, componentes de produção (plantas m-2, espigas m-2, comprimento de espigas, massa de 100 grãos e número de grãos por espiga) e produtividade de grãos. De modo geral, o híbrido A 448 White evidenciou maior nível de tolerância aos tratamentos aplicados no estádio V3. A produtividade de grãos não sofreu interferência significativa do nicosulfuron nos estádios V3 e V5, mesmo na dosagem mais alta. Assim, dentro do intervalo de dosagens avaliado, o herbicida nicosulfuron pode ser aplicado em plantas de milho-pipoca nos estádios V3 e V5, sem riscos de redução de produtividade.

Frequency of Fanconi anemia in Brazil and efficacy of screening for the FANCA 3788-3790del mutation

Fanconi anemia (FA) is an autosomal recessive genetic disease characterized by progressive bone marrow failure, susceptibility to cancer and multiple congenital anomalies. There is important clinical variability among patients and the knowledge of factors which might predict outcome would greatly help the decision making regarding the choices of treatment and the appropriate time to start it. Future studies of the possible correlation between specific mutations with specific clinical presentations will provide the answer to one of these factors. At our Center we standardized a rapid and precise screening test using a mismatch PCR assay for a specific mutation (3788-3790del in exon 38 of gene FANCA) in Brazilian FA patients. We present the results obtained after screening 80 non-consanguineous FA patients referred from all regions of Brazil with a clinical diagnosis of FA supported by cellular hypersensitivity to diepoxybutane. We were able to detect the 3788-3790del allele in 24 of the 80 (30%) FA patients studied. Thirteen of the 80 (16.25%) were homozygotes and 11 of the 80 (13.75%) were compound heterozygotes, thus confirming the high frequency of the FANCA 3788-3790del mutation in Brazilian FA patients. The identification of patients with specific mutations in the FA genes may lead to a better clinical description of this condition, also providing data for genotype-phenotype correlations, to a better understanding of the interaction of this specific mutation with other mutations in compound heterozygote patients, and ultimately to the right choices of treatment for each patient with improvement of the prognosis on future studies.

FANCD2 Western blot as a diagnostic tool for Brazilian patients with Fanconi anemia

Fanconi anemia is a rare hereditary disease showing genetic heterogeneity due to a variety of mutations in genes involved in DNA repair pathways, which may lead to different clinical manifestations. Phenotypic variability makes diagnosis difficult based only on clinical manifestations, therefore laboratory tests are necessary. New advances in molecular pathogenesis of this disease led researchers to develop a diagnostic test based on Western blot for FANCD2. The objective of the present study was to determine the efficacy of this method for the diagnosis of 84 Brazilian patients with Fanconi anemia, all of whom tested positive for the diepoxybutane test, and 98 healthy controls. The FANCD2 monoubiquitinated isoform (FANCDS+/FANCD2L-) was not detected in 77 patients (91.7%). In 2 patients (2.4%), there was an absence of both the monoubiquitinated and the non-ubiquitinated proteins (FANCD2S-/FANCD2L-) and 5 patients (5.9%) had both isoforms (FANCD2S+/FANCD2L+). This last phenotype suggests downstream subtypes or mosaicism. All controls were diepoxybutane negative and were also negative on the FANCD2 Western blot. The Western blot for FANCD2 presented a sensitivity of 94% (79/84) and specificity of 100% (98/98). This method was confirmed as an efficient approach to screen Brazilian patients with deleterious mutations on FANCD2 (FANCD2S-/FANCD2L-) or other upstream genes of the FA/BRCA pathway (FANCDS+/FANCD2L-), to confirm the chromosome breakage test and to classify patients according to the level of FA/BRCA pathway defects. However, patients showing both FANCD2 isoforms (FANCD2S+/FANCD2L+) require additional studies to confirm mutations on downstream Fanconi anemia genes or the presence of mosaicism.

Reduction of carcass weight loss in swines

The carcass fast freezing is one of the aspects of great prominence to the final quality of pork. In order to reduce weight loss, two experiments were performed, in which the carcasses were monitored during 20 hours to evaluate the main variables involved during two different freezing processes (standard and proposed) as follows: microbiological quality, storage temperature, relative humidity (RH) and air velocity. In experiment I, the carcasses were submitted to a system using heat shock (2 hours in static tunnel at - 25 °C) and subsequently sent to the equalization chamber. In experiment II, the carcasses were submitted to the heat shock and stored in a chamber with RH between 80-85%. The chambers used in both experiments showed no change in the variables studied (internal temperature of 5 °C and air velocity of approximately 0.3 m/s). However, the relative humidity in the three chambers was evaluated and significant differences were found; as a consequence, high levels of weight loss were observed in both chambers In experiment II there was an increase of RH, which reduced the weight loss of the carcasses.

Registered Nurses' Perceptions about Facilitators and Barriers to Maternal Skin to Skin Contact in the Operating Room

Abstract It is recommended that all new mothers experience skin-to-skin contact (SSC) with their newborns immediately after birth. However, SSC is not commonly practiced after cesarean deliveries. To understand facilitators and barriers regarding SSC in the operating room (OR), a descriptive online and paper survey was conducted with 68 Registered Nurses from four hospitals in Ontario. The theory of planned behavior framed the study. Nurses had positive attitudes, and believed most health care team members supported SSC in the OR, but were uncertain about their control over the behavior. Nurses who had practiced the behavior in the past had more positive attitudinal and normative beliefs, and perceived some barriers as less difficult. Attitude and past behavior were the only significant multivariate predictors of intention to practice SSC in the future. Results suggest that shifting attitude and supporting more experience with the practice may increase nurses’ implementation of SSC in the OR.
