Successful stepfamily development: Issues and implications for counselors

The traditional meaning of family as the biological unit of father, mother and child(ren) can no longer be assumed in today\u27s society. There are many other types of structures functioning in our society fulfilling all of the traditional family roles and responsibilities, and an increasingly prevalent one of these is the stepfamily . One definition of stepfamily in the literature was the complex description offered by Sager, Walker, Brown and Rodstein (1981) of one that is created by the marriage (or living together in one domicile) of two partners, one or both of whom have been married previously and was divorced or widowed, with or without children who visit or reside with them (p. 3). A more simplified explanation was given by Prosen and Farmer (1982), A stepfamily is any family in which at least one adult is a stepparent (p. 393). This latter definition is the one to be used as the operational definition for this paper

Effects of oxidized lipids (4,5 (E)-epoxy-2(E)-heptenal and 4,5 (E)-epoxy-2 (E) -decenal) and lysine reaction products on zinc and calcium utilization: assays in Caco-2 cells

The influence of the presence of brown products from the reaction between two oxidized lipids (4,5 (E)-epoxy-2(E)-heptenal, EH, and 4,5 (E)-epoxy-2 (E)-decenal, ED) and lysine (EH-L and ED-L) on zinc and calcium utilization was studied, and compared with a fructosyl-lysine mixture (F-L). Assays were carried out in Caco-2 cells grown in bicameral chambers. The Zn transported across the cell monolayer was significantly lower in the presence of the EH-L, ED-L and F-L samples, specially with EH-L. Significant decreases in Zn uptake were also observed, with no differences between samples. However, calcium transport was not modified. Thus, the assayed lipid-aminoacid brown products seem to have negative effects on Zn availability, whereas Ca availability appears to be unaffected.Se estudió la influencia de la presencia de productos obtenidos en la reacción de dos lípidos oxidados (4,5(E)-epoxy-2(E)- heptenal, EH, y 4,5(E)-epoxy-2(E)-decenal, ED) con el aminoácido lisina (EH-L y ED-L), sobre la absorción de zinc y calcio, comparándolos frente a una mezcla de fructosil-lisina (F-L). Los ensayos se realizaron con células Caco-2 sembradas en placas bicamerales. La adición de las muestras EH-L, ED-L y F-L al medio de cultivo supuso una reducción significativa en el Zn transportado a través de la monocapa de células, mucho más marcada ante la presencia de EH-L. También se redujo significativamente la captación celular de Zn, sin diferencias entre las distintas muestras ensayadas. Sin embargo, el transporte de Ca no se vio modificado. Por lo tanto, los productos pardos lípido-aminoacídicos ensayados parecen afectar negativamente la disponibilidad del Zn, sin tener efectos notables sobre la del Ca.Peer reviewe

Ganho ósseo apical a longo prazo após Instalação do implante combinado com elevação do seio maxilar sem enxerto.

Background: Assess changes in apical bone height / bone gain for up to 8 years after implant placement combined with simultaneous elevation of the internal sinus from the sinus floor (ISFE) without the use of a graft. Methods: 217 implants were placed in combination with ISFE without graft and successfully integrated into the posterior maxilla of 138 patients. Radiographs after surgery over an evaluation period of up to 8 years were analyzed. Changes in the apical and marginal bone height related to the implants were measured. Differences in bone height over the study period were assessed using the Wilcoxon test. To identify possible factors influencing apical bone gain and marginal bone loss, regressive linear regression selections and mixed linear regression models were performed. Results: In the apical aspects of the implants, significant mean vertical bone gain of 2.4 mm (mesial) and 2.6 mm (distal) was observed after 6 months (p <0.05). Radiographic analysis produced an additional bone gain of up to approximately 3.5 mm during the study period. The small initial bone height was crossed with a more pronounced apical bone gain (p <0.05). Conclusions: If the implants are placed in combination with the ISFE without a graft, a significant vertical bone gain can be expected, especially in the first postoperative year. Lower initial bone height is associated with a greater probability of greater bone gain.Fundo: Avaliar as alterações na altura óssea apical / ganho ósseo por até 8 anos após a colocação do implante combinada com elevação simultânea do seio interno do assoalho do seio (ISFE) sem o uso de enxerto. Métodos: 217 implantes foram colocados em combinação com ISFE sem enxerto e integrados com sucesso na maxila posterior de 138 pacientes. As radiografias após a cirurgia ao longo de um período de avaliação de até 8 anos foram analisadas. Alterações na altura óssea apical e marginal relacionadas aos implantes foram medidas. As diferenças na altura óssea ao longo do período do estudo foram avaliadas pelo teste de Wilcoxon. Para identificar possíveis fatores de influência no ganho ósseo apical e perda óssea marginal, foram realizadas seleções de regressão linear regressiva e modelos de regressão linear mista. Resultados: Nos aspectos apicais dos implantes, observou-se ganho ósseo vertical médio significativo de 2,4 mm (mesial) e 2,6 mm (distal) após 6 meses ( p  < 0,05). A análise radiográfica produziu ganho ósseo adicional de até aproximadamente 3,5 mm durante o período do estudo. A altura óssea inicial pequena foi cruzada com ganho ósseo apical mais pronunciado ( p  < 0,05). Conclusões: Se os implantes forem colocados combinados com o ISFE sem enxerto, pode-se esperar um ganho ósseo vertical significativo, especialmente no primeiro ano pós-operatório. Menor altura óssea inicial está associada a uma maior probabilidade de maior ganho ósseo
